Please forgive me if this is already answered, but I searched around and couldn't quite find the answer for the Asus Transformer Tf101. When I try to boot into recovery mode (via power and volume down buttons), it's not working. I'm getting a screen with the little green android guy and a triangle above his head with an exclamation in it. Any help?
That's your "stock" recovery.
What are you trying to do? The stock reocvery doesn't do anything except look for an "update" file to apply. If it doesn't detect one you get the Android with !.

I have been searching and can find no conclusive answer. I have tried to boot into recovery and when the screen comes up I select Recovery and it just takes me to the dreaded Triangle with red exclamation point. I have tried this time after time and even temp rooted and installed Rom Manager and selected flash Clockworkmod recovery and I received a selection for the MT4G and it then said Clockworkmod Recovery flashed. However when I try to do a back up it just goes to screen with device and triangle. After powering off, When I hold down the power button and volume down button I get the screen with different selections including recovery. When I select recovery it just goes to the screen with the device and the triangle. I only have 3 days left on buyers remorse and I will not keep a device that is this difficult or impossible to boot into recovery. As I am sure it is obvious that I am quite a nubie but I am trying to learn and increase my abilities. I have a Vibrant that I have rooted and flashed numerous roms on and while not an expert I am gaining confidence in working with the device.l Not so with the MT4G lease any and all help will be greatly appreciated. I am looking for positive signs to keep this phone and not send it back.

At the screen with the red triangle press VOL UP and POWER.
I had the same problem with my phone. I am guessing this you are rooted and S =off. Now when u flashed the clockwork recovery first time, it probally did not stick. So u need to go back into rom manager again and click on flash clockwork recovery. hopefully this time it will stick. This is what i had to do and it worked for me. Then bootup back into recovery and see if it works.

thanks so much for your kind reply. I did this and it did offer me another menu which included apply udate ziip wipe data wipe cache, factory reset and reboot now. At the bottom of the screen there was the following message:
E:cannot open /cache/recovery/command
I have never seen that error message before. I am not rooted and have only used temp root with Visionary. I used the reboot now and it worked. I was hoping to find a backuip and restore choice. But it is not there.A little afraid to try any of the other choices. On the second try i t took me about 3 minutes of playing around with volume up and power to get the screen again. Is this normal for this device? If so then I am quite sure I am going to return it on Friday. This phone has a lot of wonderful features and is a great solid all around phone but I am looking for something I can play around with and learn without a huge chance of major problems.Perhaps this phone is more for more experienced and knowledgeable and courageous users. I have a Nexus one that I have flashed roms using update.zip method that I am comfortable with and I am fairly familiar with Odin on my Vibrant and have flashed numerous roms with it but have never used adb although I have it set up on my computer. Both other phones are rooted using the one click root. Any further info is certainly warmly appreciated.
Hi
Someone asked me to look at their acer a500 tablet for them, when it boots as soon as it gets to the desktop, before the DE fully loads even, it comes up with a power off/shutting down message
And it shuts down
Tried the hold the volume up while powereing on and toggling the lock button factory reset 'fix' that seems to be posted everywhere but it didn't work, did once or twice get the android holding an exclamation sign thing once or twice but it did nothing from there
As far as I'm aware it's not been rooted so my question is, anyone know whether I can fix it by downloading a particular rom and trying to get that rom installed with a boot into recovery mode type thing?
Any suggestions I might try welcome
Fixed it now, found an update.zip file, applied that and it's back up and running
Thanks for looking to those that did
Hi, I have acquired an Acer Iconia A500 that was previously rooted(Or so I was told) and ran fine for months until recently. Now it only boots to the Acer Screen. Ill list what I have done so far to try to remedy this problem.
Reset
1. I hold Volume Up, Turn on the power, and switch the Rotational lock on and off until "Erasing Userdata and UserCache (I think, I see those two lines but don't really remember exactly what they were)
2. The device resets and gets stuck at the Acer boot menu.
Load an Update.zip from my sdcard.
1. This method just gets me to the Android guy with his chest open and a red exclamation point above his chest.
I apologize if threads like this already exist I have been searching for hours on how to fix this problem. If anyone is able to help that would be great!
Hello all,
Any help with this would be seriously appreciated. I rooted my Nexus 10 a while back, maybe two years ago. I'm not very proficient with this stuff. Anyhow I decided to do the OTA upgrade to 5.0...I was concerned something would go wrong unless I went to stock first, but I read that the only thing that would happen is root would be removed.
Anyhow, the tablet appears stuck while booting. I see the Google screen first with the unlocked indicator on the bottom. A few seconds later is the Android logo on its back, a red triangle over it with an exclamation point and "no command" written below". It stays that way for a minute or so, tries to reboot and goes back to the no command screen. I can't even power off, when I try to do so it just powers back on by itself and ends up at the no command screen again.
I tried booting into recovery (power, volume up, volume down). My options from here are either Start, Restart Bootloader, Recovery Mode or Power Off. Every option I choose leads to the No Command Screen (except power off, which powers off). No idea what to do from here.
Any help at all would be appreciated. As you can probably tell I don't have much experience with this and just wanted to go back to unrooted stock. If you have advice, please be clear. I can follow directions well enough, just don't have much experience here. Thanks in advance.
Same here, bootloop.
Same thing here. A seemingly short download of Lollipop (even though I have 50Mbs internet). Installation, reboot, and now it loops endlessly. I can get to the bootloader or into Download mode, but that's all. Recovery mode just reboots. I was rooted and had TWRP installed. Other than that, I was running stock 4.4.4.
I've rooted all my devices, and installed various ROM's on several devices. I have the full ADB installation. I have the Nexus Root Toolkit installed. The problem is, the device will not show up under "Devices" on the computer itself. I've installed every USB driver there is (and uninstalled each one after it does not work, so no I do not have several USB drivers installed). Of course nothing shows up using "adb devices" either. Nexus Root Toolkit also cannot find any devices. I've read everything on this subject I can find, and there are no answers out there. Anyone have ANY ideas??
Thanks
Guys, if your device is connected in fastboot (try "fastboot devices") then you can flash roms or recovery (and then flash rom) from there. There are multiple threads with the same problems out there which were fixed. E.g: http://forum.xda-developers.com/nexus-10/help/bricked-t2948546
In my example, I flashed TWRP recovery from fastboot, then installed custom ROM from recovery (official ROM failed to install for some reason). Try this, it might help.

Go to Fastboot mode (pwr+both volumes), Than select recovery after a while an android with Exclamation mark appears which is a stock recovery screen. To access the stock recovery menu press and hold power than press one of the volume keys so the menu will appear. Than do a factory reset and clear caches. You can than reboot and wait for boot animation to finish (it wont take long this time) and you will boot.
If this doesnt work you can flash a stock factory image easily from fastboot again.

I also had the same problem... I followed these instructions and now my Nexus 10 can boot normally (it took a long time to boot).
Only problem is all my data was deleted.... stup*d f*cking sh*t!!!!!!!
hello, I recieved an acer a500 from a friend, because he couldnt make it boot.
I looked around these forums, looking for an answer but nothing seems to work.
First of all, this is an european acer A500 tablet,
when I power it up, it comes the ACER logo, with a red writing in the left corner > Boot verified failed
so I tried all the factory resets possible combos, power and volume up, but nothing works.
I downloaded from this site various update.zip files, put them one by one in the SD, and tried loading them with the power and volume button, but what happens is, first it comes the ANDROID logo loading, then on the ANDROID logo comes a RED triangle, and nothing happens.
I dont know what O.S was installed here.
I also managed to get to another screen while pressing the reset buttons,
thats a black screen, with this writing in the corner > Bootloader v0.03.12-ICS: Starting Fastboot USB download protocol
That-s all I managed to do, but nothing works for me, so could someone point me out a working update.zip file, or something, to unbrick this A500 please
if needed, i managed to get the UID code with ubuntu, and the SBK key
i-m still trying all the update.zip i can find on these forums, and so far, only one managed to get me a loading bar under the Green Robot, instead of giving the RED TRIANGLE error, but after 1hour, the loading bar is stuck on like 25%
help me pls
Either babsector.rar file and flash a custom ics rom. Or the tdv4 file, which will flash an HC Rom for you.
You will need a pc, the drivers and cpuid, instructions and downloads in the root guide in my sig
