Hello everyone, i have a Iconia Tab A501 and i can't get it to work.
When i power it up it just hangs on the Acer logo. I can enter in recovery, but any rom (i tried 3 of them) that i try to flash doesn't work. The green android with the rotating 3d-thing is there but after a few seconds it's gone and at his place there is another android with the open belly and the red warning symbol.
I can't flash it because i don't have the cpuid. The bootloader is locked. What can i do?

Sorry if this is a bit late. I'm not sure if this will work for a Iconia A501(I have A500), but you can try a hard reset.
To do this, power off, hold down volume UP(not down like to enter recovery), power up, then toggle the screen lock switch back and forth (I believe you can release the power button while doing this, just keep holding to volume control) This should equate to a factory reset(I've never done it, so I'm not sure). If it doesn't work try it again(apparently it takes a few tries)
Hope this helps!

It doesn't work. It turns on showing the acer logo and hangs.
It's probably done the same as mine, died permanently. Nothing you can do about it. It's most likely that the mmc is broken or has become unsoldered. Sorry but I suspect it's toast.

How long did you wait? It takes some time to boot up first time. If you still have issues you can try force it into APX mode and flash the bootloader and recovery again, then reflash the stock ROM in recovery. http://forum.xda-developers.com/showthread.php?t=1619913
Or it could be completely dead like zardoz99 says. That would seriously suck.
EDIT:
Read again. Y U HAVE NO CPUID!?

I waited all the night.
The tablet isn't mine so i don't have the CPUID. However, it enters in APX mode and in recovery.

Sorry, being even in APX mode you can't do anything without your CPUID. Sorry, but the only thing I can think of now is to send it in to Acer to repair.

You can get the CPUID in APX mode, see [GUIDE] Recovering Recovery/Obtaining SKB.

so. i want to reflash to build 7 and update to build 8. can i fix this or my viewpad 10s become a toilet paper now ?
To enter in recovery mode, use RomManager.

can't use ROM Manager to recovery too. WiFi can't connect and when it appear allow a superuser. a program become idle and didn't do anything
Sounds like a bad flash. I'd reflash modded stock v2, then boot to recovery and wipe user data/cache/dalvik and then reflash the full 8.1 ROM. This should make sure you have a working CWM and probably fix your wifi issue too.

NO! If you are using VC 3.2 you should avoid using the ROM manager provided recovery as it is for the wrong tablet (g tablet i think) and it WILL soft-brick your Vega.
I've soft bricked my vega using this exact method!
How do I unbrick please?

When you say "soft bricked", what exactly does the tab do when you turn it on??
Best way to recover is to power down tab, attach tab to computer with usb cable. Make sure tab is charged, or plugged in at the time. hold down the back button (top of tab, next to power button), then press and hold the power button for 2 seconds, then release it while you continue to hold the back button another 2 seconds, then release back button. Your screen should flash once quickly, then stay off.
Now, if everything worked, click on the Mod Stock icon on your computer. and after a little time it will start writing files to the tab. If it says device cant be found, you are not in recovery mode, try again the power/back button instructions, it may take a few times before you get tab into recovery.
There are more precise booting into recovery instructions if needed, just Google "rooting Advent tablet"
I'm assuming you already have the usb drivers, and the roms on your computer, and know how to use them.

I have exactly the same issue! I have Vegacomb and wanted to go to HoneyIce as my son can't get skype to work BUT i can't get into Recovery in order to update. Rom Manager just reboots and all i see is the 'Warning about free software' then it just boots into VegaRom.
Would love someone to help if possible?
Thanks in advance
Well I am pretty sure I brick my asus transformer, my tablet is stuck in a boot loop all i see is the asus screen and all it does is keep refreshing that screen(boot loop). I am unable to get to clockwork or bootloader when i try to make it go into bootloader or clockwork(power Plus up button) it will freeze on the part where you have to hit up to continue. So i am thinking clock work was erased and maybe bootloader Boot loop started after wife hit the over the air update is there anything I can do to get my tablet back to working or is it just a paper weight?
Thanks for help if anyone still reads this forum
to get into recovery is
Vol down plus power
When you see words at top left corner Vol up within 5 sec.
(not Vol up + power button, that put you in APX mode)
I think I try that do you think APX mode will work for me and maybe i can push a rom that way? I will check again when i get home about recovery mode.
Thanks for the answer

If you have a B60 or prior (some B70) you can use nvflash (in APX mode) to restore a ROM.
I have a B50 so it should work but when i went to the link in android development forums it won't let me Download but I will keep trying thanks again for the help I hope this works

If your light is on, and the display is black, you are probably stuck in APX mode. Long press the power button and it should go off.
I would also plug into a charger if I were you, before doing anything else.
You will probably need to NVFlash the bootloader and recovery. If it didn't work well the first time, then you should probably be checking drivers. With the tablet in APX mode (hold pinhole button, press and hold PWR, count to 3 seconds, release PWR, then 1 more second and release pin hole.). Tablet should have black display with lit pwr button.
Plug into USB, and make sure windows recognizes it as a Recovery Device. If not, load the right drivers (I use Google USB Android drivers). Might have to load them manually.
Now, I know you wrote down your UID number somewhere, as you will need it.
I uploaded an old ver3 NVFlash package;
http://www.4shared.com/zip/Lgp9DhiH/NVFLASH_Blackthund3r_3bootload.html
Open a CMD window in the directory you extracted, and type run_all
Make sure you get your tab in APX mode, and windows recognizes it. Then follow the prompts. At the end, if good, it should say "Pass"
It doesn't require USB Debugging. If you can get into APX mode, it may work for you. If not, you might post in the bootloader threads.
Link to converting your UID to SBK is found in the guide you posted earlier.
Good Luck!

download at the top afterota and there should be a get out of apx mode, but in apx mode you hold down the power and the light will go of then you hold it again and it will boot

IF yr recovery drivers have loaded when you are in apx and yr cpuid is correct
then u may have a tab that has issues with the "bct"... the devs are working on a fix for this....
most of us with this issue rolled back to HC using timmydeans EUU then reflashed the bootloader from there with no probs...go figure???
EDIT: the EUU is for a500 you will not have 3g but its just to get back to HC with - when it comes to flashing the bootloader again be sure to
flash yr chosen ics rom first...
as far as more info take a look at civs b/l or F/R extreme rom threads (last 5-6 pages) - the flash itself should take no more than a minute
or two, i use nvflash as it provides a bit of feedback to you if things aren't quite right
you will need td's EUU link in my sig
and jazzyjames tutorial on how to rollback to HC
you will lose ALL your data not only b/c the EUU wipes it but also
ics system apps dont take kindly to being dragged back to HC so make sure you do a full wipe and format any chance you can
for running a glitch-free ICS

Heck, I e-mailed it to you also earlier.
Well, Dibb's is pretty good on this stuff, so I'll pass it to him. Try his steps. He's pretty good on unbricks also.
For me, it's a bit late. Work tomorrow mate.
Also, make sure you are using a good USB cable. You can't always use phone cables. The newer HTC USB cables work for me. This has been known to make things go wonky.

"skrilax_cz's bootloader v8"
"booting primary kernel image"
volume up+power gets me into bootmenu mode
I have a a501, it was on alexandria III and it was taking forever to boot so I figured i'd update the firmware with ICS out.
I installed http://forum.xda-developers.com/showthread.php?t=1619913 via CWM/recovery menu ver 5.5 or so and rebooted, power + volume up didn't give me a menu so I tried to reinstall the ICS bootloader, it installed like the time before except I got messages from my recovery menu like it couldn't write logs to disk (thought that was fine - thought it was being overwrote) so restarted my tablet and... nothing was unresponsive (black screen no blacklight) so I held the power button down until it shut down.
I've tried power/volume up, tried using the reset button to get into APX mode - didn't see the tablet on my computer(But I may have been impatient), tried power/volume down repeatedly, unplugged the battery and rebooted - nothing.
After I shut it down it's responsive like it's functioning somewhat, it'll turn on and off but no blacklight and nothing on the screen or vibrations.
USB debugging is on, I don't know my id
Anyone with similar problem? How did you fix it? :\

Patience and following instructions to the letter!!! You must use nvFlash to fix this - I have given you enough info for you to recover your tab BUT you cannot do anything without your cpuid - so I suggest you begin by reading the cpuid guide thoroughly first - everything you need is in there...
As Dibbs informed, when you update your bootloader to V8, you can only do this via NVFlash.
For those of us who installed all Skirlax_CZ bootloaders, the CWM function did not arrive till Version 4 of the bootloader. Only then could you CWM the bootloaders. But..... you had to be on a version 4 bootloader "First", before you could CWM the subsequent versions of the bootloader.
If you are just starting out, then you must use NVFlash to initially install any version of the bootloader.
