[GUIDE] How to rollback from ICS leak. - Acer Iconia A500

How to rollback from ICS leak
***THIS WILL WIPE YOUR DATA***
What you need:
EUU from Timmydean of 3.2.1 V4
http://forum.xda-developers.com/showthread.php?t=1307539
Your CPUID
Your CPUID was probably changed when you flashed the ICS leak.
How you can find it in the ICS leak
Download and install a terminal emulator from the market and enter in the following.
dmesg > /mnt/sdcard/dmesg.txt
Copy that file to your computer and open it or open it in a text editor on your A500
Look for androidboot.serialno= and the number is listed is your CPUID.
***DO NOT PLUG TABLET INTO COMPUTER UNTIL STEP ******
1. Download and extract root-3.2.1-V4
2. Run PBJ20upgrade.exe (right click and run as administrator).
3. Click Ok on Make sure your ICONIA TAB is not connected to a computer. If a "New Hardware Wizard" window appears, click "Cancel".
4. Click Next
5. Let it install the USB drivers
6. Click Next on Go to Settings/Applications/Development to enable "USB debugging" (see the picture)
7. It will try and scan for the current image version and new image version, this will take about 5 minutes.
8.
Follow the steps to get your A500 into APX mode.
1. Turn off the ICONIA TAB by long pressing the power button for 5 seconds.
2. Use a paperclip to push the reset button, don't release it.
3. Press the power button for 3 seconds.
4. Release the power button
5. Wait for 1 sec and take out the paperclip.
6. Use the USB cable to connect ICONIA TAB and PC
7. Click Yes
THIS WILL WIPE YOUR DATA.
8. Type in your CPUID, click next.
This will reset your tablet to a Rooted 3.2.1. Once it boots up you can install Acer Recovery installer from the market and install CWM recovery and restore your ROM or flash a new one.

Thanks for writing this up.

Thanks, i did this last night. There is another way with CWM directly installed, so you can do a CWM nand restore immediately after the process. I'll post that later today. Currently at the swimmingpool for my son's swimming lessons.

On a501
this should work on a501 too right? coz i dont see any androidboot.serialno in my dmesg.txt
edit :- it works. dmesg > /mnt/sdcard/dmesg.txt has to be issued in terminal within few seconds after we reboot the system.

THANKS!

Did you paste your cpuid with the 0x in front? if so remove them. add only 16 digits.

no i removed the 0x before pasting it and if i enter it a 2nd time it accepts it but progress bar looks and stays like this forever
[|||||||_________________________]
never moves passed that also the tab wont enter recovery says the recovery.img is incorrect or something to that effect.

Dunno why but it says please download the newer image for the upgrade... then just an exit button... does nothin?
EDIT: Never mind... I re-read the post... but I accidentally pulled the USB while it was 'upgrading' is that a problem as now it doesn't work any more?
EDIT2: Oh thank god! It tells you when it works because it says enter Acer Download Mode in the top left in small writing. Seems pretty fool-proof and robust to me, thank you JazzyJames.
EDIT3: Oh crap it failed again... now it wants me to restart it.. :'(
EDIT4: All good 3.2 booted! Thanks again.
(I put all this up for the people like me so they don't have multiple heart attacks either.)

Worked perfectly first try. Thank you!

That's more like your PC not recognizing your tablet in apx mode then. Make sure the driver is installed. If you go to device manager you will be able to check if the driver is installed or not.

i must be screwing up something simple, because when i try and get into apx mode the tablet vibrates, shows the black acer screen and instantly shuts down. i can power on just fine without holding reset but cant figure out apx mode.
a couple times i managed to get it to boot into the lock screen, says "Charging, 0%" with my wifi connecting but no screen response. works fine after a 5-second power button shut off and rebooting. cant figure out apx mode at all for some reason.

The best way to know if your in APX mode is when the screen is off and your power button is white. You don't need to be EXACT on the times of holding down power and reset, the main thing is.
Hold Reset atleast 3 seconds
Continue to hold reset and add power button.
Release power after about 3 seconds.
Then release reset, screen will be blank and power button is white, I myself noticed it works best if the tablet is not fully charged and not plugged into charge.

You should have posted a freaking warning that this deleted EVERYTHING off of our tablets. I lost pictures of my daughter that I'll never get back because of this method and there was no warning what so ever. Generally wiping data means wiping data, not /mnt/sdcard.

Just a question before jumping on this: I have installed the leaked stock 4.0.3, so I lost everything with regards to rooting. Also I can not use Busybox, SuperUser, CWM et all on my Iconia.
With this method I can fallback to 3.2.1 even though I have the stock leaked 4.0.3 installed?
Also the CPUID is not the original one from before flashing the stock 4.0.3, but the CPUID I got from flashing with 4.0.3. Is this a problem?

I am sure there are recovery tools - surely for Windows - who can help you get your "lost" pictures back.

No issues. get the cpuid of from your current rom and follow this method to downgrade. It will work.

What have we learned?
Back-up files that are important to you.
Take the time to learn about what these tools do before using them.
That being said, the OP should include that ALL data on the tablet will be wiped.
PS: /mnt/sdcard is actually in the data partition (/data/media). Custom recoveries skip over the /media directory when doing a data wipe, by default.

Hit quote instead of edit. My apologies.

Did a restore and it worked flawlesly. Thanks for the clear instructions!

Jesus..i spent so many hours trying to get the computer to see the tablet in apx mode and it just won't..any ideas on how to get the drivers installed correctly? Adb is installed and i have rooted quite a number of phones so i know its not Adb
Edit: Got it! I had to manually add the damn drivers through device manager.. thank you everyone for the help!!

[GUIDE] How to Root the Samsung Galaxy Tab 10.1 [Video Walkthrough]

A big thanks to RoboBear, tphillips, Lorddeff07, and anyone else that has helped make this happen.
I try to make my guides simple and straightforward so that the average user can root their device. I show every detail and walk you through the process. This guide is a complete video walkthrough on how to root the Galaxy Tab 10.1 WiFi with edits based on the issues that some may run into with previous guides. Without further ado, let's get started!
LINK TO MOD EDITutdated links
◄●REQUIRED DOWNLOADS●►
Just download, do not install or run anything yet.
◄●Instructions●►
This method is done on Windows. I recommend this way as its the easiest. If you don't have Windows, borrow from a friend.
◄●Downloading Files and Installing Drivers●►
Download the I have linked.
Extract the zip file by right clicking and selecting "Extract All," or by using an extracting program of your choice.
Open the folder and double click the driver file labeled "GT-p7510_USB_Driver_v1_3_2360_0-Escape.exe"
Install the driver. Its pretty much just Next, Next, Install, and Exit when its done.
◄●Connecting the Device●►
Turn on USB Debugging by going to Settings>Applications>Development and checking USB debugging. Click Okay to confirm
Power off the device by holding the power button and selecting Power off
Put the device into Downloading mode
Hold the Vol Down button (the left Volume button) and then hold the Power button as well.
Keep holding until you see two icons. First you'll see the Samsung Galaxy Tab 10.1 logo and then the icons will show up. Let go.
Press the Vol Up button (the right Volume button) to select Downloading mode.
Connect the device to your computer with the USB cable.

Select PDA
Double click the clockworkmod recovery file labeled "recovery-cwm_4.0.0.4-sam-tab-10.1.tar.md5" to select it.
Click Start
Once it is complete, you can close the program
◄●Completing the Root●►
Disconnect your USB cable
On your device, turn off USB Debugging by going to Settings>Applications>Development and unchecking USB debugging
Plug your USB cable back in
On your computer, go to the same root folder as before and transfer the zip file labeled "Samsung_Galaxy_Tab_10.1_root.zip" to your device. Don't put it inside any folder.
Confirm that it was transferred by clicking inside the device folder
Power off the device by holding the power button and selecting Power off
Put the device into Recovery mode
Hold the Vol Down button (the left Volume button) and then hold the Power button as well.
Keep holding until you see two icons. First you'll see the Samsung Galaxy Tab 10.1 logo and then the icons will show up. Let go.
Press the Vol Down button (the left Volume button) to highlight the left icon.
Press the Vol Up button (the right Volume button) to select Recovery mode.
You should see that you are in ClockworkMod Recovery. If not, start over
Use the volume buttons to highlight "Install zip from SD card" and hit the Power button to select it.
Use the volume buttons to highlight "Choose zip from SD card" and hit the Power button to select it.
Use the volume buttons to highlight "Samsung_Galaxy_Tab_10.1_root.zip" and hit the Power button to select it.
Use the volume buttons to highlight "Yes - Install..." and hit the Power button to select it.

Hit the Power button to select "reboot system now"
Your device will reboot
You're now rooted!
Excellent Guide.
Thank you.
This one is Noob-Safe
I love how you have proper grammar and punctuation skills. Spacing is good, fonts are bold where they need to be, this is how a guide should look!
All guides should be written like this, can u offer classes for the uneducated?

Would there be a higher demand for that than my guides? lol. But thanks a lot, I appreciate it Just trying to make it easy for everyone.
Wow. A guide that is easy to follow, in plain and understandable English, and thorough!
Thanks a lot! I'll be following this when I get my Tab this week.
perfect instructions! Thanks!
just rooted this way. It was the easiest root I have ever done!
I have rooted two different androids and the rooted process took really long on my other phones. This took me the same amount of time as your video.
Very good guide.
1,000,000 points for not hosting your files on one of the uber-annoying file hosting sites. I used your video to root my EVO phone as well, have been waiting for your guide for the 10.1. great job....
All done, started after posting my thanks and now I am all rooted..(sp?) Just need an Easy Button boot screen after the root.
Perfect guide
Does this work with 16GB WIFI UEKME 3.1 tab?

Thanks for the detail root instruction, it is very clear easy to understand (I have clicked the thank button).
Question: Just want to confirm whether this root method only applied to wifi only tab or applied to all wifi and 3G tab and with different version.

Unfortunately this is just for the Wifi only version. I could probably make a written guide for the others, but I don't have the devices to support that. Sorry dude.

Boot loop and no recovery mode ability
Sorry in advance for the long thread.
Great documentation. I hope you can help me. I posted the below at the stickied root thread but I haven't received any responses. It seems I blew away recovery mode. My tablet consistently boot loops. I have the option to choose recovery but when selected the screen goes blank for several seconds then reboots. I can get into download mode but my PC doesn't recognize the hardware and will not install the proper Samsung drivers. After reading your thread I'm wondering if this is because I didn't set debugging mode properly.
"Hi all I need some help. Verizon LTE 10.1 tab is boot looping after attempting bone head maneuver. Attempted root per Lorddeff07's method. Installed recovery file, system rebooted. Installed kernel file, system rebooted. Installed clockwork mod premium from market. Installed clockwork mod recovery for galaxy tab. Initiated backup via cwm, system rebooted and started boot looping. I can get into downloading mode but when I try to access recovery mode the tablet starts to boot loop.
I tried odin but the USB drivers are not installing properly. If I force the driver to install as Samsung ADB the tablet will display "start odin" when in downloading mode. However the odin app does not recognize the tablet. I'm running W7 pro Sp1 x64.
I also tried to use nvflash per shep211's tutorial but that didn't work. I get to section 2 step 17 when the command fails and the tablet will disconnect from the PC.
I know there has to be a way to fix my fUP. can anyone asist?"
FIXED: Removed the Verizon SIM card. Booted into download mode. Manually added the unrecognized driver as Samsung Mobile USB Serial Port. Opened odin flashed the ltecwm.tar.md5 file. Rebooted. All is good. Rebooted into recovery and installed root using Samsung_Galaxy_Tab_10.1_root.zip. Everything is up and running.
Thank you so much nice eay guide just rooted my tab thanks to you!!1 I pass you a beer sir

[Q] Can't reboot into recovery in VegaComb 3.2 Build 7

i have some issues with a vegacomb 3.2 in a booting into recovery. my device is Viewsonic Viewpad 10s. in first i'm update to bluetooth fixed problem. everything work fine untill i update and get some issues
1.WiFi can't connect at all , all of it. no secure , WPS , PEAP , WPA WPA2
2.can't recovery with CWM or power button
i can't do anything with that all so i try to factory reset and i get it ****ed up .. OTZ
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.

Would love someone to help if possible?

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!
MD
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

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!

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.

[Q] Bricked?

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? :\
edit: apx mode is indeed working

"This bootloader can only be flashed using nvflash. You can use the guide here http://forum.xda-developers.com/show....php?t=1622425"
This is from the OP of the thread you linked to...and is the reason you have ended up "bricked?" If you had followed the guide you would have saved yourself alot of grief....You cannot, I repeat, cannot flash the bootloader or an ICS rom via cwm
I've tried power/volume up,

This is "fastboot mode" only available on the unlocked bootloader
tried using the reset button to get into APX mode
Click to expand...
Click to collapse
to get into APX MODE use a paper clip to press and hold the reset button,
then press and hold the power button for 3 secs and release it - after another second release the reset button.
Your tab screen will be black and the power light will be on
- didn't see the tablet on my computer(But I may have been impatient),

yeah, impatience can cause alot of problems - to fix this you must have the acer drivers installed and the USB drivers from the android sdk

you must get this to have any hope of recovering your tab - go to the cpuid link in my sig - theres a guide there by "srbeen" on how to retrieve your cpuid with linux - the only other way i know for someone in your position is "usbdeview" - that is in the same post,
Anyone with similar problem?

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.

[Q] Another A500 Stuck in APX Mode

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!
dibb
