chismay · Apr 28, 2012

ok so rooted and loaded the 1.031.00_ww_gen1 for my tab.

installed everything cool nice looking no screen or wifi probs at all.

ive since decided i would like to try flexreaper as ive heard it has the ring and faceunlock working,

so i check my recovery is working so i can flash a new update.zip

when i try to enter recovery i get this message:

rasing cache before SD update
SD update cmd: recovery
--update_Package=SDCARD:update.zip
Booting recovery kernel image
(IN RED) Recovery verified failed

if gone to acer recovery installer and tried installing the cwm1.3.4 and 1.7 both by thro2002ro but to no avail still the same error,

i also installed clockworkmod and tried installing the recovery there and rebooting .....to the same error ....can anyone help?

For those who need the solution :
I presume this should work to downgrade from any ICS builds as well .

just fixed that problem been at it for almost 10 hours to find a correct solution

get your correct UID . In my case there some weird problem UID wasnt diplaying it all (insted i was seeing serial number even with adb devices..) ... use backup_tool to get UID works greats hands down !
get it from this link
Click to download

if that doesntt work look across the forum on how to find your UID

once you have that get EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
get it from this link Click to Download

dont plug in iconia tab let it search for firmware about 5 min eventually it will ask you if you want to restore it say yes and input your CPUID (same as UID) Then put the TAB Into APX MODE

Hold power +reset button for 3 sec then let it power go one sec later let reset go you can use board pin

and plug in your usb cable .

This process may take upto 10 mins ... or less
sit back it will be restored back to stock ! HC 3.01

thats it

nvflash utility did not work for me !

Read , read, if you installed the leak or received the OTA from Acer to ICS you need to unlock your boot loader and install custom recovery.
There are at least 2 threads in dev section about it.

The problem is all xda developers are working under M$ Windows programs. Where are the MacOsX dev?
I'm waiting for a good soul to develop a MicroSD or Mac ICS bootloader unlocker...

Hi all,

Booting recovery kernel image

Nothing important on my a500, i would like to reinit the system and install FLEXREAPER-R14-1.033.00_1.031.00-ICS.

Thank you for your help

Gill

Hmm nothing has worked for me. Have tried several things. Sometimes the Acer Utility says bad cpu id, then it says its trying to install. Tried ApX Flash but my tab does nothing. I get a power light and that is it. Well maybe another day or two I will figure it out.

Not sure what u mean by Acer utility, but the first thing u need is ya cpuid - the flash wont work without it....

I get a power light and that is it. Well maybe another day or two I will figure it out.

the 2nd thing you'll need is the Acer drivers, run the setup.exe. turnntab off and get into apx with button press, then check device manager
that u got acer boot recovery drivers installed under USB controllers, if they not there then check adb interface for apx drivers, as long as
u have one or other u shud be all good

blueis300 · May 8, 2012

I tried the PBJ upgrade and my CPUID said it was fine but sat at install and never did anything. Tried the APX FLASH and it says complete but still cant do anything.
Says all drivers are installed. It lists apx mode but when I do ADB it doesnt list any devices. Also never lists anything in device manager.

with the euu . did u keep tab disconnected till u got the 'cant detect yr iconia tab screen" then button combo into apex mode?

tawhid111 · Jun 14, 2012

There seem to be some problem with (64 bit os) try using 32 bit windows....
-Tested over windows 7 32 bit no problem
-Tested over windows 7 64 bit no problem

Double check your cpuid in the folder the file called CPUID.txt inside EUUs_SBK_Acer_A500_1.016.05_COM_GEN1 folder
make sure it match or else youll get invalid cpuid error

make sure your cpuid in in cpuid.txt is written like this 0x0YOUROWNCPUIDGOES HERE example 0x037c624942c11318

and also when entering it in PBJ20upgrade add a 0
example 037c624942c11318

if you need more help pm me

have you tried the new apx flash updater and a500 manager from blackthunder? it lets you go into recovery from your pc and you can flash a new recovery and bootloader ...very easily i think your on the locked bootloader thats why you cant get into recovery like i was,. i installed a PATCHED UNLOCKED bootloader and now everything is cool

its in civato's guide page you can use this guide to flash a unlocked one, (v4+)
http://xdaforums.com/showthread.php?t=1622425

make sure u have a backup and your cpuid!!!!

Optional A500MANAGER
What does it do :
· One-click APX Mode entry
· One-click Recovery Mode entry
· One-click fastboot entry for patched bootloaders
· Instant logcat viewer
· Instant dmesg Viewer
· Function which dumps the dmesg to a text file on the desktop
· Serial number extraction to make SBK calculation exponentially easier
· Links to ICS Root, A500 APX Flash Tool and two download links (Acer and my mirror) for USB Drivers
· Shows what mode the tablet is in at the bottom

Spaces?

Does the SBK extracted from the CPUID need to be entered without spaces?

so with V3-APX-PACKAGES

*******************
What he implies is:
1. He used the Manual Modem to Goto APX First Black screen. [ instructions can be got from: blackthund3r_A500_APX_Flash_Tool_v0.3-V3BL-CWM tool under Manual Mode]
2. Then he Used/Resumed with the blackthund3r_A500_APX_Flash_Tool_v0.3-V3BL-CWM, tool under the Automatic Enter APX Mode, till he got APX logo.

3. Went to Bundles and selected recovery_thor There is Option 17. This is First Step when RUNNING blackthund3r_A500_APX_Flash_Tool_v0.3-V3BL-CWM.

4. Then finally Recovery is flashed Perfectly. So u can install any custom ROM.
