I'm looking forward to your findings.
Hopefully it will work in different situations, only had the chance of testing and debugging it on my tablet.
will this work on my PB Liberty Tab (G100W) running HC 3.0.1?
my android version is 3.0.1
and build Number is PB_G100_1.013.02_EMEA_GENS
great share!

If this a500 version works fine for everybody, i intend to make a a501 version of it. I advice not to use it on A501 because on ics it seems that the a501 has different bootloaders.
I want actually to install ICS Custom/stock rom with ICS bootloader,
Could you tell me the steps to follow,
Once I install ICS bootloader while I am on HC stock, then I cant boot, so should I flash a ICS rom from CWM immedietly after installing ICS bootloader? or I have to install ICS stock Rom first then ICS bootloader??

1) best to put the ota update zip on the root of your sdcard
2) boot your tablet with vol min pressed until you see recovery image loading
3) then you will end up or in the actual recovery you installed or it will begin flashing the ota ics
4) when you are on ics and you have enabled usb debugging, you can then flash the matching kernel for the ota you had installed (eg version 1.031)
(without the correct kernel on ics, certain recoveries wont work)
5) after reboot, flash recovery and bootloader again
6) remove the sdcard from your tablet, remove the update.zip and put for example flexreaper or any other cwm rom on it. put sdcard back in your tablet.
7) reboot your tablet into the recovery and flash your custom rom you put on your sdcard in the previous step, and your good to go.
you should have done the update.zip method in the first place, or go to ics through the official update system.
Many thanks for the Guide,
I will try as guided...
for Packard bell, official ICS updates are not rolled out yet...
only one doubt in the item 1 you mentioned is internal SD or external SD??
thanks again
Ok I tested it , my conclusions:
-Tablet info section= 10/10
Very easy getting your cpuid and SBK , one click , nice.
-Back to stock= 8/10
I get it but I do hope the new users get how it works so maybe more info with link to full packets thread and link to decrypter thread .
-HC= 9/10
In browse , I would remove the custom bootloader , for HC you only got the A501 and A500 bootloader , for some it would seem that they can flash a custom HC bootloader like on ICS. (My opinion , thinking on newbies)
-ICS=10/10
Everyhting what you need is there.
-Kernel and root = 7/10
Tricky stuff here , maybe better to provide the full stock kernels also (no sys rw hack)
Also I would make clear that only installing the root doesn't give you system/rw acces without installing the hacked kernels.
And make clear that these are not tweaked or OC kernels.
(you are free to add kernels from my thread and if you need a combination just pm me)
-extra stuff =10/10
Overall 9/10 , I flashed a few recovery's and bootloaders using the pre build in packages and using browse and picking my own stuff , really nice and easy !
Maybe a idea for later and do the same as my m8 blackthun3der and allow prebuild packages (.a500apx).
For the A501 , if you download the flash tool from my guide you will find the bootloaders for the A501 in there , if you can't find them let me know !
edit
One question , did you use the correct bootloader to go into apx because for ICS V6 it is a different one then to use when you install HC bootloader. (reason)
Download my tool package from the guide and look for
dlmodeblhc.bin = for a500 getting into apx when installing HC bootloader
dlmodeblhc501.bin = for A501 getting into apx when installing HC bootloader
dlmodeblics.bin = for a500 getting into apx when installing V6
dlmodeblics501.bin = for a501 getting into apx when installing V6
and then you got the HC bootloaders
hcbootloadera500.bin
hcbootloadera501.bin
And ICS bootloaders
ics_boot_unlk_V6_500.bin
ics_boot_unlk_V6_501.bin
Works perfect for me! Thanks! Makes things a lot easier

i meant external sd
I just went back to full stock hc 3.01 on my g100w, stock bootloader and stock recovery, through the update zip method. (one ive downloaded from vache's romlist), i enabled usb debugging on that system and imediatly flashed ics bootloader 3.14.6 + thor recovery v1.72 from the "ics" tab on my program.
Rebooted the tablet afterwords and i could not boot into honeycomb like you say. Then i removed the external SD card from the tablet and put ota ics version 1.031 on it, put it back in the tablet and rebooted the tablet with vol min pressed.
Thors recovery came up, and i did :
1) "choose zip from SD card"
2) in the next menu i choose "update.zip"
3) in the next menu i choose "yes install update.zip"
4) it starts flashing the official ota ics
5) after flashing go to "wipe menu" and do : "wipe data" , "wipe cache" and "wipe dalvik"
6) after that go to "power menu" and reboot your tablet
7) go through the initial android setup (choose wife, choose language etc)
8) enable usb debugging in your android settings (its in the "options for devellopers" section, just above "about tablet"
9) fire up afterota v1.00
10) go to the "kernels and root" tab
11) if you installed ota ics v1.031 then install the corresponding patched kernel, in case of v1.033 choose the other one etc. and start flashing the kernel.
12) if kernel flash is done, shutdown and reboot your tablet into android
13) once you see the android lockscreen press "reconnect tablet" on Afterota (on "tablet info" tab)
14) go to the "kernels and root" tab in After ota and press the "copy" button to copy the cwm root package to the internal sdcard of your tablet. If its done your tablet will automaticly reboot. If you see the android lockscreen proceed to the next step
15) press reconnect tablet in Afterota, if connected proceed to next step
16) go to the "ics" tab in Afterota and flash your recovery of choice again, the only difference between "install a500" and "install g100w" buttons is the bootloader logo, so its not a desaster if you think you've hit the wrong button. If see pass on the screen of your tablet proceed to next step.
17) shutdown and powerup your tablet holding the vol min button pressed to get to the recovery, go to "install from zip file", "choose zip from internal storage", choose "cwm_hc_ics_root.zip", choose "yes install ..", go back, "power menu", "reboot" and let the tablet boot until you see android lockscreen.
18) now in Afterota, reconnect tablet, go to the "extras" tab, and "remove recovery killer script"
Tadaaaaaaa : fully rooted ics + custom bootload + recovery

You have some really good tips here, i'll try to import them into the program in the next release. Thank you very much for reviewing the program !
Many thanks again mate,
You have already typed a lot for me, sorry to bother again,
OTA HC 3.0.1 was rooted before you flash ICS bootloader from your program??
If I need only a working ICS rom on my Tab, not rooted no CWM, can I stop at the instruction no.6
A500 / A501 bootloaders have tiny difference (aside from the bootlogo, which I changed back to "green Acer"). I shall probably make V7 universal.
However, can you update the tool packages not to flash V3 - it doesn't allow custom BL updates via. CWM (full support for that is in V5 via both CWM and fastboot).
I was just wondering if someone could point me to what I need to go back to stock and get OTA updates, I live in the US and would like to know which file to download, or does it matter? Do I need the full package? and which honeycomb version should I do? and which file under the version of Honeycomb should I get? or does it matter? Sorry about being n00bish I just would like to get back to stock so I can start over with this thing and get the info down about it.
Hi,
I've been using AfterOTA to go back to stock. It's very easy. I used version 1.01 which isn't available now but 1.07 should still be able to do the same thing.
Which file you use is important as they are geared for different regions of the world. A lot of the files from the Full Package thread aren't there anymore so your choices are limited. It needs to be a full package though, it should be over 300MB. An update won't work.
Basically, you use AfterOTA to install the bootloader and recovery from it's stock tab. Have the update.zip file on the root of your SD card (some of them need to be decrypted). After the tool installs the stock recovery boot by holding down the left or top volume key. That will automatically install whatever update is on the card. Version 1.01 had separate ICS and HC bootloaders I'm not sure how 1.07 is set up. Then just let the update process happen.
I doubt that you'll find anything earlier than HC 3.2 for your (our) region. If you just want a stock ICS tab you could just use that update.zip and skip HC entirely.
Good Luck
Can you point me to the stock ICS zip we would use for our US tabets? I found a page on here http://forum.xda-developers.com/showthread.php?t=1113878 but they dont have an ICS Full Package and I don't know which HC 3.2 one to use. it says to look at my current version but I am on a flexreaper ROM. I want to remove the recovery and bootloader and go completely stock and upgrade to OTA ICS so I can then run After OTA to get a fresh new recovery and ICS bootloader. thanks for your help.
My stock 1.104.02_COM_GEN1 OTA'd to 1.033.00_PA_CUS1.
From Vache's thread the Acer_A500_7.006.01_COM_GEN2 file will update to 1.033.00_PA_CUS1. I don't think this file needs to be decrypted.
1. Download that file. Put the update.zip file on the root of your SD card.
2. In AfterOTA on the stock tab choose A50x. This should install the HC bootloader and standard recovery.
3. Disconnect the tablet. Power down the tablet. Reboot by holding the left or top volume key while pushing the power button. This should start installing the update.zip on the card. If you wind up in CWM then AfterOTA didn't work and you'll need to downgrade.
4. Try to boot after the update. It will probably get stuck at the logo. If it does you'll need to hard reset (bottom volume key + power + slide rotation locker). It takes a while for the first boot and it might crash once while setting everything up.
5. You should be in HC 3.2 from here you can OTA all the way to ICS. You'll need to install the ACER update enhancer from the market b4 it will see the ICS update.
I hope this works for you.
CWM Recovery booted, instead of flashing the update.zip, How do I do it now?
I don't know why AfterOTA isn't working for you. I really thought it would. Oh well, Gersma says it's only for OTA. There are other people who probably know better, but I think you're going to have to get a stock bootloader on there before you can use any of those files. My guess its that you'll need to follow the downgrade guide. Search on "rollback".
I hope you find a better solution, but the rollback isn't that hard.
Good luck.
what if I apply the update.zip from CWM using the "apply update from sd card"? would that just force the up date and wipe everything with the stock bootloader and ROM that is in the update.zip?
I don't think that file will work from CWM. Maybe one of the stock ICS leaks would work. If you can load one from CWM it can load the BL and it will replace the recovery when it reboots. Then you should be able to use AfterOTA to return to stock and upgrade through the OTA's.
Hello,
I have an A500 with 8GB, bought in USA nov 2011.
it is currently running Thor/TegraOwners ICS ROM v164 (with CWM recovery)
my back-facing camera stopped working and I would like to go back to stock to send the tablet in for repairs.
I got the full stock firmware from here: http://forum.xda-developers.com/showthread.php?t=1113878 (Acer_A500_0.000.00_4.010.10_COM_GEN2_1310535068614_9b84abb1)
unfortunately, I'm not having much luck flashing this :| ... I decrypted the zip and extract the update.zip and put it on the sdcard.
-tried applying update.zip through CWM ... no luck (it extracts but nothing happens)
-tried installing stock recovery using 'acer recovery installer' ... no luck (i get the android with exclamation mark when i try to go into recovery)
acer recovery installer shows bootloader version 3.01
any ideas ?
thanks

First off, get your UID number just in case you need it. You can get it in the Dev forum (sticky). Always have your UID written down somewhere.
Then go to the "all files" Sticky thread in the Dev forum. Where they have all the Acer roms and updates.
Download 2 or 3 of the a500 ICS Update files. These are full update files.
Decrypt them if needed, then pull the update.zip out. Copy to EXT SD Card, and boot holding Vol+ and PWR till you see the text about installing, then release.
Might have to try more than one, but eventually one should install. These are full update roms, not patches.
Should give you a stock ICS. Hey, check your camera, might start working again

Hello Everyone
Thanks for the XDA to help me bring my Dead A500 back to life
after getting my uid in ubuntu and obtaining skb and formatting the whole Device and partitioning it, i am finally on stock 3.1
But I cant find an Official OTA that could get me to stock 3.2.1, and in xda site, i searched and i found the only OTA stock 4.0.3 , when i try to flash the ota stock 4.0.3 using stock recovery ie (volume down + power + update.zip in SD) After flash, i end up with a dead tablet.
tried some other ICS rooted roms and all the same, they get me to a dead tablet.
only 3.x versions will boot after flashing.
My a500 is a 16gb Gen1 , it was on the Official stock 4.0.3 , it suddely bricked for NO reason, after using V8 i got nvflash error and pointed to Root 3.2.1 ,, 3.2.1 gave me several unsuccessful tries, but suddenly one of that tries worked, successfully installed root 3.2.1 but thought i could go for ICS, after flashing ICS , i ended up with a bricked tablet.
So I again flashed stock 3.1 and luckily my tablet boots into the OS . Acer A500 4.010.40.com.gen1
What should i do. what rom should i use to go to stock 3.2.1 (or what should i do to go to stock 4.0.3 or non-stock 4.0.3)
only these two roms work for me after Stock recovery flashing:
Here are two Gen 1 roms provided by dibb_nz . Please say thanks to her.

Hope this helps
hi everyone
i'm explaining the problem that's getting me crazy!
I've got an a500 tab. it was HoneyComb 3.1 at first, I downloaded ICS 4.0.3 Stock Rom and installed it via SD Card, Power + Vol- button.
i've been using it a few monthes now i want to use a custom rom like tegraowners JB.
my current version of rom (ICS 4.03) can't be rooted with ICS Root for a500 because it's version is'nt supported.
so i decided to install a 3.1 HC Stock rom, root it and use custom roms.
i downloaded 3.1 stock rom, named it update.zip and copied it on a sd card.
inserted SD card in tab and turned it on with Power + Vol-. here is the problem!
first i see recovery mode loading then an android logo with a (!) sign on it.
cdn.gooyait.com/uploads/android-recovery-mode-600x276.jpg
and tab get's restarted...
any idea?
I don't know maybe i've downloaded the wrong rom.
if yes please link to the correct rom for thei version:
Kernel Version:
2.6.39.4+
Image Version:
Acer_AV041_A500_RV21RB01_WW_GEN1

Stock recovery probably isn't designed to flash anything other than ICS. (Or it can't go backwards?). As for rooting, the blackthud3r ICS root tool oughta get ya done. (There are 2 methods, search and find one. For your case I recommend number 2)
[Anyway, don't worry about rooting the stock ROM, on an A500 this doesn't help you get jellybean.]<- MAY BE WRONG. In order to install a custom ROM, you must install a custom bootloader and recovery. Here is a guidehttp://forum.xda-developers.com/showthread.php?t=1622425 Once you've gotten through that(and assuming you haven't died of heart attack), you can install a custom ROM. Just follow the instructions on said ROM's thread. My favorite(albeit, a bit buggy) one is here :http://forum.xda-developers.com/showthread.php?t=2239476&highlight=jellybean+rom&nocache=1. Good luck!:good:
EDIT:
You need a CPUID to flash your bootloader. I don't know if you need root to get that.
Install a custom bootloader
You shold read about custom bootloader, it isnt that difficult, you get root of your iconia, download a flex software it automaticly downloads the latest recovery I recommend TWRP, and from ther you could touch the option install and select you zip file
