F2 button not booting PC into recovery mode and Multimedia Controller error in device manager.
Hello everyone,
I updated my lenovo ideacentre b540p from windows 7 home premium to windows 8.1 pro. I have two issues that came up after the upgrade.
1. I can no longer access the Lenovo rescue system 3.0 by pressing the F2 button during startup to boot into recovery mode which was possible when I was using windows 7 and because of this I am unable to install the software and drivers that came with the PC.
2. In device manager the multimedia controller driver is not installed. It shows a yellow sign in the other devices group. I have tried different version from the lenovo support site but none of them work. The PC was shipped without a CD containing the drivers but if I can access the rescue system, I believe I will find the driver I need for the multimedia controller.
Solved!

Hi RR7,
You might have a look at this page: http://forums.lenovo.com/t5/IdeaCentre-Desktops-Home-Servers/Windows-8-Recovery-partition-not-recogn...
It's Windows 8 related, but you'll better understand what may happen when your cloned HD has not the same size as the original one.
interesting post, thanks. sadly i'm not sure this really helps. i didnt find what i expected.
the reagent.xml only has two references to offset, and they both refer to the partition that contains windows 7. i have changed this offset on the cloned disk to match the actual partition offset but it makes no difference.
i don't see any reference to the hidden lenovo partition or its offset in the windows recovery.
i also cant see any reference to it in the BCD on either the source or clonded disk.
all i see if pressing F2 on the source OEM when powering on loads a special lenovo recovery environment, and doing the same thing on the clonded disk just shows the windows 7 boot loader option for choosing to boot windows or do a memory test.
my question still remains, what is the magic thats happening when i press F2?

I went into recovery mode - and keep receiving error 4005 - tried different usb, computers, did all updates possible nothing helps, my iphone screen shows apple logo and constant waiting circle
Same here. I tried to update my iPhone 5S and iPad 4 to 7.1 but iTunes wiped out them. This thing already happened for iOS 7.0.6 update. What happened to Apple? I am really curious whether Apple is aware of this problem.

Hi there could someone out there please help i've got a Iphone 4 running on IOS 5 and it will not come out of recovery mode> It comes up with the error code -1 which i've looked everywhere on the web but no one seams to have the same issue.
This is a reconditioned replacement phone from the apple genius guys which i paid £130 for and only got 3 months warranty with and as soon as the warranty run out it crashed on me and never been able to get it back out of recovery mode. I've been back to the apple genius guys and they have told me there's nothing they can do other than charge me £130 to take the phone off me and give me another reconditioned phone with a 3 month warranty. Which as you can properly tell i dont want to.
PLEASE PLEASE HELP ME thanks for your timeThis is a bad hardware error, Baseband Error. Some have reported getting through this error by Restoring iPhone with the SIM Card removed. Try that. Try restoring with different computer. Search Web some more for other thoughts.

IPhone 4, Home button not working, stuck in recovery mode and boots straight into voice control.
After trying everything and failing I still cant work out why this is happening.
I cant restore my phone in itunes, just get an error. My phone boots into voice control for no reason and to top it off the home button stopped working along with all these errors. It cant be a hardware issue. I sent it in and got told I had water damage which is impossible as I treated the phone like gold.
Does anyone have a reasonable explaination as why this is happening and maybe even a solution?
Thanks!try to put your phone in recovery mode. plug into itunes and hold down the home button and top button until apple logo appears and then let go of the top button only. the phone should display plug into itunes.let go of the home button when this happens. disconnect iphone and plug it back in itunes should recognize it is in recovery mode. hit the restore button on summary page.

Booting into recovery mode and Web service in 10.7 server
I have two servers: Server A is running 10.6 server and server B is running 10.7 server. Both are on the same LAN at a data center. My questions are as follows:
1 - is there a way to restart server B into recovery mode remotely? (and not using a KVM)
2 - if server B was booted successfully into recovery mode is there a way to screen share with it from server A? If so how would this be done?
3 - can Apple Remote Desktop reboot a 10.7 machine into recovery mode and still continue to see its screen?
4 - in the Server app of 10.7 server there is a default website setup in the Web service. it doesn't seem possible to edit any of the information for this default website, is this true?
5 - is there any way to get the Web service in the 10.7 Server Admin tools? it is missing among many other services.
ThanksProbability is very high that you have a hardware failure. You should get an external bootable drive (or startup with a bootable DVD if you can) JUST to prove that it's not the motherboard, but probably the hard drive that's failed.

My son let one of his friends use his ipad. The next time he tired to use it he could not get it unlocked, I tired to unlock it but it kept telling me that I had the wrong pass code.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.

Try it and good luck. You have nothing more to lose if it doesn't work for you.

My iPhone 4s randomly went into recovery mode and iTunes can't get it to restore.
Last night my iPhone randomly went into recovery mode on me. Just before I went to sleep a bunch of static lines appeared across the screen. The screen went dark and a few seconds later the Apple logo appeared. A few seconds later is disappeared. A few seconds later it came back. So on and so forth. I thought I had turned it off and was going to deal with it in the morning, but when I woke up the iPhone still just had the Apple logo going on and off again.
I've tried everything today. All the different button hold methods out there. I've tried to sync it to iTunes but the same **** keeps happening over and over again.
A message pops up saying "iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes." So I press OK. Then I press the "Restore iPhone..." button on iTunes. It asks me if I'm sure I want to "restore it to the factory settings" and I click "Restore and Update". It then says that its "extracting software", "preparing the iphone to restore", "waiting for the iphone", then "verifying iphone restore with Apple". As this is going on the "connect to iTunes" sign is shown on the screen of the iPhone. When the "waiting for the iPhone" part starts, my screen goes black, then the apple logo pops up. The "verifying iphone restore with apple" comes on the iTunes and the status bar appears underneath the Apple logo on my phone's screen. It sits there for a couple of seconds with no progress and then the screen goes black. Then iTunes has the same **** message saying "The iPhone 'iPhone' could not be resotred. An unknown error occured (9)."
I've gone through this process countless times in the past few hours and have done everything that apple support has told me. The windows system is fully updated. So is the iTunes. I've restarted the computer. I have no idea whats wrong and its making my blood boil.
A couple of notes about the phone:
It's over a year old. It's never had water damage. It was nearing the max capacity of its internal storage. This has never happened before. I keep it in an Otter Box. I had very little problems with the phone. Lately a couple of apps like snapchat and the barstool sports app were taking a little longer to open up or would randomly close out and sometimes my camera would take a while to get going. But this problem is just ridiculous and completely rendered the phone useless.Hello Sean,
It sounds like you are constantly needing to restore your phone because it keeps going into recovery mode. Usually putting a device into recovery mode and restoring it can help isolate an issue to your iPhone hardware if an issue persists afterwards. I would try manually putting it into recovery mode and restoring it 1 more time:
If you can't update or restore your iOS device

If that does not resolve it the symptoms indicate to me that it is a hardware issue causing this to happen and would seek service for it:

i was in the process of jailbreaking and updating my ipod and when i was updating it,it went into recovery mode and now i cant get it out of recovery mode so what can i do??
Go elsewhere:
Jailbreaking voids the Apple warranty and also means that you will not get any support from Apple, including from this Apple forum. Jailbreaking can't be discussed in this Apple forum.

My ipod touch wouln't turn on because I dropped it, so I plugged it into the computer. It went into recovery mode and is now stuck on a waiting for ipod screen. The ipod shows the apple logo and and an empty loading bar. Please help. Thank you.
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
