How to re-flash a bricked WRT310N back to the correct firmware version

I accidently flashed my WRT310N version 1.0 with version 2.0 firmware. After which the router was dead as a doornail.
After a frustrating 3 hours of reading forums, following over 11 tutorials, and being 1 second away from throwing my WRT310N at the wall, I finally fixed it.
I performed this fix on a Windows 7 32-bit PC. My provider is Comcast.
STEP 1:
Visit http://homesupport.cisco.com/en-us/wireless/lbc/WRT310N and click on the DOWNLOADS tab.
Select Version 1.0 firmware from the drop-down menu.
Download the appropriate firmware. At this time this was posted, the version is 1.0.10 build 2.
SAVE the firmware to your desktop.
Download TFTP2.exe and SAVE it to your desktop.
Firmware
09/09/2010
Ver.1.0.10 build 2
Download 3.08 MB
STEP 2:
Open up a command prompt by going to the start menu, type "cmd" and hit enter.
You should see C:\Users\abc> (where "abc" is your username).
Type in ping -t 192.168.1.1 -w 10 but DON'T HIT ENTER yet. Just have it ready so you can press enter later.
STEP 3:
Launch TFTP2.exe located on your desktop.
In the "server" field type: 192.168.1.1
Leave the "password" field blank.
In the "file" field, browse to the firmware file you previously saved to your desktop.
Set the "program retry" to 10 times. (any number above 10 is fine)
DON'T HIT UPGRADE YET. Just have it ready so you can press upgrade later.
STEP 4:
Go to your Control Panel > Network and Internet > Network Connections.
Right-click on your active "Local Area Connection" and go to "Properties"
Highlight the "Internet Protocol Version 4 (TCP/IPv4)" item and then click "Properties"
Change the automatic settings and set a static IP of 192.168.1.2. Hit OK and back out of the network settings.
STEP 5:
If your router is farther away from your computer, try to pull it within reach of the mouse and keyboard. You will need to multi-task once pinging/flashing begins.
Make sure you only have one ethernet cable connected from your PC to the router. The cable should be connected to any one of the 4 blue ports. I connected mine to port 1. DO NOT CONNECT IT TO THE YELLOW INTERNET PORT on the router.
With the router in your hand, hold down the reset button for 30 seconds until the port 1 light goes out then immediately disconnect the power while still holding down the reset button. DO NOT LET GO OF THE RESET BUTTON!
WAIT 30 more seconds with the power disconnected. (Do not let go of the reset button)
PLUG the power back in and WAIT another 30 seconds. After that, let go of the reset button. You should have held the reset button for a total of 90 seconds. This will wipe the router's nvram.
STEP 6:
PREPARE FOR FLASHING!
Bring up the command prompt window that you prepared earlier. You should still see the ping command that you entered in Step 2. Now, hit ENTER to start pinging the router continuously. You will probably see a bunch of "request timed out" responses.
Bring up the TFT2.exe window that you prepared in step 2. Press UPGRADE so it can begin communicating with the router. Make sure you set at least 10 retries.
As quickly as possible, go back to your router and HOLD the reset button and disconnect the power. You don't need to wait 30 seconds...5 seconds is enough. While stil holding the reset button down, plug the power back into the router and keep an eye on the command prompt and TFT2.exe windows.
If the command prompt has successfully pinged the router, TFT2.exe will begin to flash it and very soon it will show a success message below the progress bar. If you still can't successfully ping the router, close and restart TFT2.exe using the same settings and try disconnecting/reconnecting the router's power again as mentioned in the paragraph above. You may want to try holding the reset button down longer than 5 seconds. I was able to get this to work on the FIRST TRY. Hopefully it works for you.
WHAT TO DO AFTER SUCCESSFULLY RE-FLASHING YOUR ROUTER
Now that your router is has the proper firmware, go back to your adapter's settings (mentioned in step 4), delete the static IP and set it back to the default automatic settings.
Plug your cables back in and don't forget to plug the ethernet cable from your modem to the yellow internet port on your WRT310N.
Just to be safe, you should probably do these three things:
"Recycle" the power to your cable modem by holding down the reset for 60 seconds or disconnect it from the power outlet for 60 seconds.
Reset your router by holding the reset button for 30 seconds. (No need to disconnect the power while holding it.)
Restart your computer.
SUCCESS!! Good luck.

I recently rebuilt my iphoto 09 library and now all the pics are in one folder instead of events. How do I get 20,000 pics back into the correct events?

I recently rebuilt my iphoto 09 library and now all the pics are in one folder instead of events. How do I get 20,000 pics back into the correct events?
I have a macbook pro Version 8.1.2 and I am using Iphoto 09
I rebuilt library because many pics were black and now they are in one folder labeled "Recovered"

Do you have the original iPhoto Library (before you rebuilt it)?
If so, I suggest you rebuild it using iPhoto Library Manager, a program you can download. It does a better job of rebuilding. It also leaves your original intact and makes the rebuilt Library a new file (package).
If you don't have the original (say, from a backup), then you should probably first back up the library that you have before trying anything.
After making a backup of it, look along the left side, you will see Events and Photos. Is there anything in either of those areas?
If not, it sounds like all your photos were recovered and put in Recovered during the rebuild. iPhoto Library Manager might do a better job with this. In any case, if there are no photos in Events or in Photos, try selecting ~ 5 photos in Recovered and drag them to Photos. Do they then show up there with the correct dates? Do they also show up in Events after doing that? I am suggesting just a few photos before you try it with 20,000.
If the photos inside your "recovered" area are also in Photos, then don't do the above steps. I'm not sure I can help you if your 20,000 photos are in Photos but not Events. I'd try iPhoto Library Manager instead with its better rebuild.
If the 5 photos experiment works, then I would try it with ~ 200 photos at a time, going through your entire collection. You'll need to do this about 10 times if you really have 20,000 photos. Remember, don't do this if the "recovered" photos are already in "Photos."

My iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat, every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats??

hello my name is kirstie, i updated to firmware 4.2.1 .....my iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat, every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats the same problem??

I have reset the phone, full firmware restore, even downgraded back from firmware 4.2.1 to .3.1.3 official by using dfu mode and still doesnt fix.
(i correctly got out of dfu mode after the downgrade)
i can enter dfu mode and recovery, and update through itunes with no problem, but it doesnt fix the problem,

Anyone have any suggestions? or is everyone else just as clueless as me !

There is nothing wrong with your Dell, it will work fine with any MacbookPro. I have been using Dell displays for over 12 years with many different Mac models. I have two 21" Ultra Sharp displays working side by side to design a Keynote presentation right now.
The issue your having is with the way Keynote takes control of the video output to both displays, it sends the presentation signal to one and the presenter display to the other, this is set up in;
Keynote preferences > Presenter display.
If you want to show a wesite or another app on either display, use application switcher:
press the the command key on the keyboard, then the tab key; a row of applications will show what applications are running, choose which one you want to show. Use command > tab to return to Keynote.

I updated to new ios and now it is not syncing properly. How can i revert back to the previous installed version?

I updated to new ios and now it is not syncing properly. New songs are not showing up on the ipod display but when I view the device on my computer, they are in the playlist but there is a dashed circle beside the missing songs. It previously synced perfectly before the IOS update. How can i revert back to the previous installed version?

Downgrading the iOS is not supported by Apple.
Try:

Dotted circles next to songs, won't sync, red circle with square?

My ipod is somehow synced to another library, because I plugged the charger to a wall. How can I sync my ipod shuffle back to the original Itunes library without erasing my current data in the Ipod shuffle?

",the owner sold the ipod without clearing the songs and since the songs were not puchased from the itunes store then i believe i now own the songs"
Not true at all.
It does not matter where the songs came from, they are not yours and the previous owner does not own the right to distribute them to others.
The law is the same with downloads and cds and any other medium.

Place the device in DFU mode (google it) and restore as new.

I use my iPad to get the address book backed up by iCloud from my iPhone. However, I cannot see the recent new contacts from my iPad. Is there anyway to check the iCloud server to see if my address book backup from my iPhone is still there?

When i try to restore my Back up using Itunes this is the message i get - "Unable to restore backup as the software is old - Please setup as a new device and then try to restore your backup" - Please advise. If i do so are there any chances of loosing my data. At this point in time i would be happy if i could just retreive my contacts list. Any suggestions would be greatly appreciated.

Nope - you cannot restore a backup from a newer iOS version on to a device running an older iOS version. The reverse works, but in your case to use your backup, you must update to iOS 7.0.3 - no other option if you want to use that backup.

Firefox 6 forces you to log into e-mail again & again, since you can't view an e-mail & simply close that tab.. I want to close the tab, not exit the function I am in. How do I uninstall Firefox 6 & go back to the previous version?

With Firefox 6, you can't close the tab you are in and remain in the program; opting to close one e-mail means you are forced to exit the (e-mail) program completely and then go back into it...this is ridiculous if you are trying to read all your e-mails...not have this issue. How do I uninstall Firefox 6 & go back to the previous version?

I am unwilling to attempt navigation away from these sites. The pop-ups that occur on the attempt to leave a site or to close the browser are exit traps offering incentive to stay.
Once upon a time, when the internet was less dangerous, I would be willing to close the exit pop-ups. Now, after twice being infected with malware trying to close the pop-ups, I now force close whichever browser I am using.
Recently, I clicked on the red X to close one pop-up, and it installed a trojan that I had to pay to be removed. When I clicked on 'Leave' in another exit pop, it didn't exit and it turned out I was giving permission to run a script file. Now that criminals have learned these exit pop-ups can be used to force a click action, the sites using them have become dangerous.
If I force the browser to close using Task manager, Please tell me how to stop FireFox from sending me directly back to the same site because it mistakenly believes it crashed when it did not. I forced it to close because I was on a site that had taken control of my browser and was not allowing me to leave the site.
No other browser sends me back to the potentially dangerous sites. I prefer Firefox, but the new version must have a setting that allows me to get safely away from a problem site?

I delete an individual message but the time I received the message is still showing next to the persons name in my inbox instead of going back into the correct date/time order. Anyone know how to fix this?

SOLUTION
Open "terminal" on your mac and type the following:
defaults write com.apple.mail IgnoreSortOrderWhenSelectingAfterDelete 1
(copy and past the whole line)
This will stop that behaviour in mail.
It works on most opperating systems.
mine is.
