7941G stuck in firmware upgrade loop

I have a brand new 7941G phone that we attempted to change from SCCP to SIP for testing. We placed the contents of the firmware zip file into a tftp directory and pointed DHCP option 66 to that tftp server and started the upgrade process. The phone grabbed the term41.default.loads file serveral times over several reboots but now it appears to be stuck in a loop. It no longer tries to pull any files from the tftp server, it just sits with the upgrading screen and then occasionally reboots itself. It is getting an IP address, so that we know is working.
Any ideas?
Thanks

Alistair-
Thanks for the help. We managed to get the phone back on it's feet and loaded with a SIP image. I removed the 8.5.3 images fromt the tftp server and placed the 8.5.2SR1 and 8.5.2 images on the server instead.
However, when I power cylced the phone it still did not pull the new image (or any files for that matter). A previous poster said to take the phone off the voice vlan. I tried this thinking I was maybe handing some bad information on my voice vlan DHCP settings. The phone started to pull the new firmware once I moved it from the voice vlan.
I went back and checked my dhcp settings on the voice vlan and everything looked good. The phones must have some kinda feature or bug in the bootloader that if it gets the same IP address from a DHCP server it eventually stops trying to pull and image. Once the ip address changes, it tries again for some reason.

E90 stuck in firmware upgrade

Hi,
I am in the process of upgrading the firmware on an E90.
It seemed to be nearly complete, then it announced that it could not find the phone (it is still connected through a USB cable).
Now it has been on a screen "Updating the software" with 1 second remaining for the past hour. The E90 shows "400.34.93 Test Mode" on a white background.
It tells me I should not disconnect or close the updating software.
Any suggestions on what to do next.
Many thanks
Roger
Solved!
Go to Solution.

Hi rogernye, I have experienced a similar situation in the past, during upgrade of latest firmware the PC suddenly indicates my E90 is disconnected, it puts me in a dilemma whether to abort & disconnect.
But I also have to heed the warning of the consequences of damaging my handset, I can't recall the exact steps taken but for sure it was disconnected or aborted & I tried again, fortunately the phone didn't suffer any damages.
If indeed your phone is damaged after disconnection your alternative to take it to the Nokia care point to have it upgraded there, good luck

My Verizon Stuck in unending Upgrade loop

I just purchased a Droid Incredible 2. When I tried to use the My Mobile Verizon Widget (preloaded), it said I needed and upgrade and sent me to the App Store where my only choice was to update the My Verizon App. Once the update is installed, trying to open the app just pops up a message that says an update is available and sends me back to the App Store. Clicking on the install again, I get an error message:
"Sorry! The application My Verizon Mobile (process com.vzw.hss.myverizon) has stopped unexpectedly. Please try again."
This error message will appear each time the phone wakes up which is annoying and can be bypassed by a forced stop and uninstall of the upgrades.
If I uninstall the update it still prompts me that I need an update. It won't ever open the actual app. In the app store there are endless 1 star ratings with exactly the same issue. Will Verizon ever fix their own app?
I've read all the previous forum posts about this and have done all the things they suggested - soft reboot, hard reboot (battery out and back in), reset of the apps. Nothing works. I can always log into the actual site instead of using the app but it seems like the app would be so much more simple and you would think that, if nothing else, a Verizon app on a Verizon phone should work!

I've been having this problem too. I just tried what was suggested (clearing the data and cache) but that didn't seem to work. I opened the app again, and I still get this message: "A new version of My Verizon Mobile is available. Please access the marketplace to download the latest version." I can click either "upgrade" or "cancel." Clicking cancel exits the app and I get a text message from Verizon that says to restart the phone after upgrading to prevent further upgrade prompts. But if I try to download an upgrade, I run into the same problem mentioned before.

Iomega Storcenter ix4-300d stuck at 95% after firmware upgrade

Hi,
I upgraded my device after I got an email that there is a new firmware:
An update to version 3.2.10.30101 of the Iomega StorCenter ix4-200d software is now available
I installed the update but now it is stuck at 95% after rebooting.
Never had any problem before the firmware upgrade.
Any advice?

Hello BelgianTomas
I recommend that you first power down the unit if the unit has not completed the boot process. Then re-seat all disks and try booting the unit again. Please do not try to access the web interface until the power led is solid white.
Next would be to try moving the internal disks to different bays to see if a different drive order wil allow the unit to boot.
If that does not help, LenovoEMC suppor should be contacted for more advanced options.

6220 Classic Firmware upgrade - stuck / any ideas ...

Am trying to use Nokia Software Updates to do a firmware upgrade to my 6220 Classic from v 03.06 to v 03.46.
All going smoothly until the stage when the updater tells me : Updating the Software, please wait... Estimated time left : 15 mins.
This has now been reading like this for about half an hour - clearly it's stuck.
Any ideas ? Lots of grim warning about "Don't disconnect etc etc".
Thanks.

I ended up solving this myself simply through persisting. Dull and clunky process, but I ended up ignoring the "do not disconnect..." warnings. disconnecting it, and starting all over again.
Strangely, and I hope it's different for you, I now have a phone that confirms that it has the new firmware loaded up, but I see no discernible difference in performance, battery life etc etc. Close to a waste of time, if Nokia cares (which I don't think it does).

SG300-28 switch in boot loop after firmware upgrade

After performing a firmware upgrade on an SG300-20 switch from ver 1.1.0.73 to 1.2.5.70 the switch now boots up with the following error and resets:
30-Aug-2011 10:47:33 %L1Mngr-F-PARAMTOOLONG: csco-sb parameter %s is too long.
The attached file contains a full output of the console boot process.
I have tried loading different versions from the console, but all produce the same error.
Has any one any idea how to resolve this issue?
Thanks
Des

Hello Tom, Thanks for your reply,
I had done the process before with the 3 firmwares offered in the cisco website. I did it again, and i get a boot loop again, with following error:
%L1Mngr-F-PARAMTOOLONG: csco-sb parameter serialNo is too long.
Any ideas?
Thank you,
Nico

Firmware upgrade stuck

My router says there is still a firmware upgrade in progress. I have flashed and reflashed (using UI and tftp util) multiple times, and this will not go away.
This is all on top of erratic behavior, dropping the connection, periods of no connectivity, periods of degraded performance, etc.
I've tried a factory reset, and holding the button in for 30 seconds. Nothing will get this perpetual firmware upgrade to go away.

Anytime a firmware upgrade is interrupted (for whatever reason) before it completes, there is a serious risk that your router will die. However, there is always some hope. Please try the following:
You need to try again to reset the router to factory defaults.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
If you cannot get "Reply from ..." in step 9 above, your router is dead.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you.

Help..I updated my iphone4 to iOS to 7.1.1 from 6.1.3 at last stage of firmware upgrading throwing an error 16 and stuck in recovery mode.

HIAll
I waited so long not to update of my iphone4 to 7.x.x because of bugs and not much stable for iPhone4 and many reviews from friends saying phone is very slow and many bugs but after release of iOS 7.1.1 of many improvements for iphone4. I tried to update my iphone4 to 7.1.1 through iTunes at last stage of firmware upgrading its showing an error occurred error (16). I checked in internet error16 is purely hardware issue before my phone is very good condition in iOS6.1.3 no problem with my phone, But after upgrading to how it will be hardware issues. why Apple engineers are not testing properly their software’s before releasing great updates to customers now my phone is out of warranty and I can’t use it anymore just showing iTunes symbol and charger on the screen while on/off showing apple logo. From the past September there is no proper solution for error 16. Don’t know what these people are doing about that error why apple is crashing customer phones by releasing useless update to phones what is the point of buying such a expensive phones don't know what to do with this phone. Tried many possible ways
Tried: presing home+power button at 95% of firmware update
          Disconnected battery and restored
          used DrPhone to restart
          tried to restore old version 7.x.x
          no luck.
          used new original cables
          restored with Macbook
          tried to restore in 3 Different computers and so many times but no luck

Hi, to get your iPhone 4 back to normal, here're two ways for you.
1. Use Dr.Fone for iOS. The free trial version can fix iPhone screen of death. The free trial version can do that, you don't have to pay.
Just download and install this software on your computer and connect your iPhone 4 to computer with a USB cable. When it detects your iPhone 4 is abnormal, click Restart the device to get your iPhone 4 to be normal.
2. Use iTunes to fix it.
Step 1. Make sure that the latest iTunes is installed on your computer.
Step 2. Plug into a USB cable to connect your iPhone4 to computer.
Step 3. Press and hold the Home button and the Sleep/Wake button at the same time for about 10s.
Step 4. 10 seconds later, release the sleep/wake button. But continue to hold the home button until a message comes out, saying "iTunes has discovered an iPhone 4 in recovery mode, you must restore this iPhone before it can be used with iTunes".
Step 5. Click your iPhone 4 in the left sidebar to show the device control panel on the right. Then, click Summary.
Step 6. Go to Backups section and click Restore Backup.... In the drop-down list, choose a backup file and restore to your iPhone 4

How do I get around this. I upgraded to WRT54Gv5v6_1.02.5.002_fw.bin and now when I reboot this is all I get. If I try to go to another version I don't get connectivity. I only have connectivity for this part then I lose it.
Every time I type in 192.168.1.1 I always get this display....
I've tried to hold the reset up for 30sec the first time then 1min.......then unplug for 10 to 20 seconds, (still holding down the reset button) and reconnect. Letting go of the reset button once it's connected.
Is the router gone? Will I have to get another one? Would like to get your input.
Thanks

Download firmware file again. And browse for it, and upgrade it. Reboot router, it might work.

ZenV Plus STILL stuck in recovery mode after firmware upgrade

=Hi there,
My ZenV plus opened in recovery mode for no apparent reason... I have tried every option to try to fix it, including downloading and installing the firmware upgrade - this generated a message saying the upgrade was successful but the player will still only start in Recovery Mode after trying to reboot it. So what do I do next? Thanks in advance for any and all helpful suggestions.

AHi,
Can you please try resetting the ZEN V Plus to see if it helps?
To reset the player, use a pin to press the reset button.
Did this happen out of the blue?
Do you have any contents in the player? If you do, please remove them to see if the player is booting up properly.

Winxp keeps rebooting - can't finish the firmware upgrade

The firmware upgrade was almost done. Itunes told me to not disconnect the phone until it re-appears in i-tunes. Then never happened - Windows said "USB device detected - digital still camera" and then my computer rebooted (after briefly showing me the blue screen). It keeps happening - I'm stuck in a loop Ideas?

2.I updated the webcam drivers
3.I disabled the device in Device Manager
4.I disconnected the webcam
5.I connecedt the iphone
Things worked this time.

Firmware Upgrade and Battery Life?

Since the firmware upgrade on my Macbook in early February the fan appears to be running at full speed all the time and battery life is crap! Has anyone else noticed this? Is there a fix/workaround available please?

Sounds more like an app stuck processing that shouldn't be....does happen from time to time. Behing hot means it is constantly processing.
To fix:
Try a reboot (described below).
Think of it this way, the iPhone is more of a computer than a phone. It suffers from being a new OS and nobody can deny there are not bugs and memory leaks. The longer left running, the more things start to fail or slow down (I have had the iPhone since day one of original phone and I am just speaking from my experience). Thus I equate it to like when Windows95 came out...not sure of your age or if you remember those days...but back then it was a running joke of how many days you can keep Windows 95 running before you had to reboot. I am sorry to say but the iPhone is the same way right now (but getting better with a few hiccups back during the 2.0 release). So for me, I reboot daily when I leave in the morning and take it off the charger. By doing so I rarely see any lag or problems.
A reset/reboot is:
Go to Home Screen
Press and Hold Home Button
Keep holding and press and hold Lock Button
Keep holding Both
You will see Slide to Turn Off (Don't let go to slide, just keep holding)
The phone will turn off (in time, but screen will look like it has some white lines)
Keep Holding
When you see the Apple Logo, you can let go.
Turning off via the Slide to Turn off while good and fine to turn off, is more like the Sleep Mode on a computer. Thus any locked up issues in memory remain when you turn back on. A reboot as described is like doing a real Turn off and Turn On on a computer.
You may also wish to read this tread about reboots and odd application behavior.
http://discussions.apple.com/message.jspa?messageID=5851978#5851978
For me, 2.1 works great.

Firmware Upgrade causes severe slowness and Hangs

Has anyone else encountered this problem? I did do the firmware upgrade, and that caused slowness in responsiveness (followed immediately by that spinning wheel). In some cases, it completely hangs. At this time, I also tried to VNC into it, and it wasn't listening. It looks like GUI and network connectivity got hosed. This happens at least 10 times today.
Any suggestions?

spingineer,
I haven't seen the firmware update (done 2x) alone cause the problems that you're mentioning. In fact, I didn't notice a thing after running it. I DID notice issues when I ran all the updates (machine fresh out of the box and then everything at once). You machine shouldn't be any slower. Make sure you have enough free space on your drive.
The obvious, and often underused, diagnostic tool is to create a new user account and see if the issues persist there. If not, then look to what's running in your login items and your applications. You may just need to repair permissions, but sometimes it helps to verify or repair the disk.
As to the network connectivity. I'd say it's basically a given that a lot of minis aren't good citizens.
What I see is contention. It's like the machine thinks 'oh, someone else is using the connection so I'll back off a bit then try again', even if nothing else is on at all. It could be partially hardware, there are changes in the machines; but it might be something that can be solved w/ modifications to the stack. It's almost like a feedback loop. The more you use the connection the more it thinks it is competing w/ other machines for access and the slower it becomes. Try the usual, zap the pram, repair permissions, etc. There's a good link if you use search to a tutorial that may help you w/ some network connectivity issues on the mini. (moving out system configuration, promoting your primary connection to the top, using the assistant, rebooting and zapping the pram).
As easy as it seems to look at the firmware as the source of the problems, I haven't seen that as the foundation issue for either of the difficulties you are experiencing with your machine.
Hopefully a few simple resets and permission repairs etc will remedy the issue.
Good Luck,
-j
