I am trying to get my bricked A500 into APX mode. From what I understand you use a paper clip/pin or other object to push and hold the reset button and then power up. Holding the power button for approx. 3 seconds after power up and reset button approx. 1 more second. Tablet screen will go blank, power button will be lit and tablet is in APX mode. On my tablet I don't "feel" anything when I try to push the reset button. The pin goes in and just stops without any feeling of any button being pushed. I cannot get the tablet into APX mode. It just boots to the Acer screen. I do not have my CPUID and from what I understand, APX mode is my ONLY option to get it back. Has anyone had problems with their reset button? If so was there a resolution? Do I have any other options to get my CPUID and flash something to get my tablet running again? Thanks in advance for any help.
Search for Ubuntu recovery cpuid in this forum. Make you you get a 64bit live CD and follow the instructions on how to get your cpuid to get your sbk. It took me a few days to figure it out but it worked.

Thanks for the reply, but that requires me to be able to get my tablet into APX mode. That is the issue. The reset button does not seem to work. The Ubuntu method is what I was pursuing until I realized that my tablet will not go into APX mode. I either need a way to get my tablet into APX mode or another solution to the CPUID problem.
When u push the reset button correctly, u will definitely feel it click...don't use something with a point on it, a paperclip works best but anything with a flat end to it, an earring/nose or tongue stud will do if you're 'pierced up' lol...
Once u 'get the click' press and hold the power button UNTIL the power lite comes on AND THEN start your 3 second count...release the power button and after a second release the reset.
For cpuid, as daroota said, Linux is the only way if you do not have a nandroid backup...if you've previously had your tab connected to your pc, u can use the 'usbdeview' tool...all info and links in the cpuid guide in my sig.

How to do I put my vega in nvflash mode? I have a custom rom now and I did that before but I forget how. Everywhere where I read I get steps to get into ClockworkRecovery Mod but I need to get into nvflash. I want to instal a new rom but I stuck on this little thing
Hi there
This has been covered before, lots of times. Please use the search function before starting a new thread. It just adds clutter to a great forum.
Here: http://forum.xda-developers.com/showthread.php?t=1179538 i answered in post 7.

Take it easy
I read that and I tried that. What I get is that power off screen with, power off, restart, recover options and when I push power button slighty less my screen shuts down but nvflash doesn't apear in device manager, nothing happens
Nothing appears on the screen until you start the rom install. Check its in the right recovery in your device manager on the pc. Nvidia recovery should appear in the usb section. If not reinstall the usb drivers from the advent website.
Good luck.
Rememeber that the vega must be plugged.
I finally did it, thanks a lot! The problem was what you don't need to push buttons for 2 seconds each, just 1 second hold did the trick

Actually it is easy to put your Vega type tablet into nvflash mode without a power cable attached -
1 Press Poer button to start boot.
2 As soon as the screen lights up, press and hold down the POwer button until the boot is aborted and the tablet goes back to being pwered down.
3) Immediately start the Back Button, Power buttin, Back button routine and the tablet will now successfully go into nvflash mode.
Enjoy.

hm, i have to hold the back button for at least 3 seconds on my surfer MN10U, only then it responds to debug mode by clicking power. i even dint get a feedback from windows. i only see it when obening hardware manager and see a "nvidia debug device" under usb devices.
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

Hey MD,
I didn't get that file from you still, but i got my tablet to shwo the logo and the white text again by running the a500apflashtool\nvflash.exe but still not luck with passing Flashing Bootloader (EBT) stage one - formatting partition...
I would love to get more info on how to get pass this.

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.

I have spent all night researching this forum, and have had no luck finding a solution to my problem. My tablet is stuck at either the lock screen (15% battery, no touch controls) or "shutting down" loop, all depending on how I power it up. Most of the methods listed on the forum either involve flashing updates via SD card (none have worked so far) or require me to load a bootloader via PC connection (which I cannot do since I cannot access tablet settings). Does anyone know how I can get this thing working again? I assume that an OTA update was mishandled by the previous owner, and this is the cause of the brick. Any help would be greatly appreciated.
Thanks in advance!
You do not need access to the power settings to be able to boot into APX Mode. If I remember correctly you do the following:
Press and Hold Power Button
Press and Hold RESET Button (Using paperclip or pin) for 3 seconds
Release RESET Button
Release Power Button
It will appear that the tablet doesn't boot, but if you then plug it in to you PC with a usb cord to the miniUSB port it should recognize it as an APX Device in the Device Manager. This should let you do the BlackThund3r's recovery method, or any other method using APX.
I have done all of the BT, TD and babsector stuff with no luck. APX mode is easy enough, but it doesnt help so far.

Hi there,
I have an A500 Iconia Tab that's been stuck in APX mode for a while now. I've tried to retrieve my info with blackthund3r's tool but nothing worked. If anyone could provide a step-by-step for me, it'd be greatly appreciated.
I've also tried resetting my tab by holding down the vol- and power button, that didn't work either.
Thanks,
Rich
You need the cpuid b4 you can do anything, that's yr first priority. See the cpuid guide in my Sig.
To get out of apx mode, just rebo or....hold the power button until the white power led goes out, then power on again - hold pwr button in 5 secs till led comes on. Now, wot do u see??
If you've bricked it or it won't boot to the OS run the babsector file in the root guide in my Sig.
Make sure you have Acer and sdk drivers installed. If yr pc is 64bit or win 8 you'll have a mission on yr hands. I think someone has posted a workaround in last couple of days but don't quote me on that

Hey Dibb,
I've already tried everything in your sig to get the CPUID:
(1) From a PC using Blackthund3rs A500 manager - start --> opening server ---> stalls ---> closing server
(2) From your device using Terminal Emulator App --> Can't access tablet
(3) From USBDeview must have previously used the Tab under HC with the PC you're using --> Tried, not located
(4) From a uid.txt in any Honeycomb-cwm backup in external_sd/clockworkmod/backup/"your_HC_backup" folder --> no backups available
(5) From adb devices if you're running honeycomb --> N/A
(6) From cwm 1.7.2 via on screen display and a text file - great if you are on ICS already --> Can't access tablet
(7) From a working system in /sys/firmware/fuse/acer_cpuid --> Can't access tablet
(8) Gersma's OTA Tool --> turned off UAC and tried but tool claimed to have problems accessing tablet even though Device Manager had tablet as "acer-recovery"
Toggling the power button does nothing - it's white when the tab is powered "on" and dark when the tab is powered "off".
I have never seen the ACER logo that others have seen. My screen has always been black.
I definitely have the Acer driver installed but which SDK drivers are you referring to? I've tried installing the Google and Naked drivers found on this site but they didn't help.
I think I tried babsector as well but I don't recall what happened, but since my tablet is still non-functional, I'm going to say it didn't work ha.
Any other ideas?
Linux is the only other way, srbeens method.
If u think u have the drivers installed correctly the only other thing I can suggest is to power off. Then put yr tab in apx mode via the buttons. Getting the reset button in can be 'awkward' but timing is not so crucial. As long as there's a delay between the holding in of the reset and pushing the pwr btn in - then a delay between releasing the pwr button then the reset. Don't use a pin or anything sharp to push the reset pin in, they can slip off easily, use a paperclip, an earring stud...anything with a squarish, flat bottom.
Then run babsector or any other EUU based Rom. Leave the auto tools alone for the meantime they're no use to atm.
Good luck!
