ok I have been searching im lost in a sea of forum topics that dont seem to either work or relate to my GTAB . I have an original Verizon 3g 7inch Galaxy tab I would like to try a rom on it but it seems that my root method no longer works. but i cant seem to weed through the forums to find info on rooting it since its running the updated gb 2.3.6 is there a post out there in this vast sea of a forum that can help me ???? anybody ????
I wanna root so i can load cwm and install AOKP rom
I answered this question earlyer toady. http://forum.xda-developers.com/showpost.php?p=24634979&postcount=2
Thank you but i still am having issues with cwm installing.
Can someone please explain to me this problem and how i can fix it ?

First you need to do some recommended reading to understand how this awkward system of flashing from heimdall and the various recoveries.
This explains what can happen to your tab should you mess up.
http://forum.xda-developers.com/showthread.php?t=1133590
This explains how to revive your tab from that mess if it is possible. Also shows you how heimdall works.
http://forum.xda-developers.com/showthread.php?t=967175
Finally, this shows you how ClockworkMod Recovery works. To get to CWM Recovery on the galaxy tab hold volume up and the power button.
http://www.addictivetips.com/mobile...-and-how-to-use-it-on-android-complete-guide/
This should give you an idea of what can go wrong and how to fix it. Read carefully because you can disable your device to a point where you can't fix it and will have to send it to somebody who can.
Now there are two ways you can proceed from where you are at:
Flash a rom that doesn't have assert problems in the version of ClockworkMod Recovery that you have installed.
or
Directly flash a recovery and kernel from heimdall.
The easier and safer route is to just flash one of the roms that can be flashed from your CWM Recovery. This one will give you a working MIUI rom and CWM Recovery 5. Just follow the instructions from the CWM Recovery tutorial I posted and the instructions from this link.
http://forum.xda-developers.com/showthread.php?t=1365089
The second route will give you experience on heimdall. Recoveries can be flashed using a recovery.bin and a ZImage file in heimdall. This will let you put CWM Recovery 5 on your tab no matter what rom is installed on it. Unfortunately the zImage kernel is not compatible with the stock rom so once you install this you will only be able to start the device into CWM Recovery.
http://cl.ly/AGBB - CWM Recovery 5 recovery.bin & zImage
To install fire up heimdall after reviewing the directions from the return to stock/heimdall tutorial and put recovery.bin in the recovery slot and zImage in the kernel slot.
Ok update thanks for helping everybody i have aokp working now but it doesnt seem to have any hardware accelaration its running slower than dirt
Ya I bricked it its done for good now can't get it to even turn I have no clue what I did.
guess I'm done unless there is a miracle cure out there
I'm 50/50 for rooting and flashing devices this is the 2nd device (first was an og Droid never bricked it) I attempted to play with in this fashion and its done as far as I can tell.......
Thanks

Hi guys welcome to the weird and wonderful world of the acer tab!!!!
Things are very different with this device, whats 'normal' for other android devices is not 'normal' for our tab!!!!
So first of all, dont try installing cwm or a rom the 'normal-this-is-the-way-I-did--it-on-myphone', you will end up with a brick!!!
2nd, you both have working systems at present, so we'll try to keep it that way.
Open up a file explorer and navigate to this:
/sys/firmware/fuse/acer_cpuid
One of the first things that are different is this: acer_cpuid
It should look something like this:
288424344009597 - now u need to add a 'zero' to the front:
0288424344009597 - this is your cpuid, back it up in multiple places if need be, just dont ever lose it - IF anything 'goes wrong' at any time you will NEED this number to save your tab from eternal brickdom!!
3rd once you do get your 'cpuid' go to the 'sbk generator' here.
This generates your 'sbk' or secure boot key and will give you something like this:
0x93588800 0x33CE8901 0x0BED6D03 0x30737899.....
OK then, now you have your cpuid/sbk you can start thinkning about what rom you want to install on your tab.......
Read the OP(Original Post) of your desired rom. This will tell you EVERYTHING you need in order to flash it - remembering always that 'Acer' does not do things the 'normal' way!!!!!!
Most of the custom ICS/JB roms on here all require the 'patched / unlocked bootloader'... In fact, even installing a custom recovery, cwm, twrp or public recovery, for the first time....will require the BL to be 'patched' first....and yes, even flashing this is not done the 'normal' way....tho the process can be complicated there are PLENTY of guides and auto tools to make it easier for you....
The 'patched bootloader flash' will also include a 'custom recovery' too, and you can choose from 3-4 options....amazing but i'd advise to use cwm 1.7.3, until u get up and running, after that you can go crazy flashing anything you like!!
So basically there are 5 main steps to getting a custom rom installed.
1. Install the Acer Drivers and the android_sdk drivers
2. Get your cpuid and generate your 'sbk'
3. Your desired rom is on your external sd card
4. Put your tab in 'apx mode' which allows u access to download mode
5. Install the patched v8 bootloader/recovery - either manually using nvFlash or using the auto tools.
Personally I prefer the manual nvFlash method, if you get an error it will at least give you an error message...the auto tools will just get 'stuck'
Check the 'bootloader' thread OP for a guide to manual nvFlash and the patched bootloader package here
There is also a step-by-step in my sig!!!
If you want to use the auto tools then apxFlash tool, or afterOTA tool you can find both in the 'bootloader' thread. And a step by step for apxflash tool also in my sig....or this excellent one here by user jdgM3NT4L here...
please be sure to read these posts very carefully and if there is something you do not understand then please dont hesitate to ask , there are plenty on here who will help you thru the process....AND its easier to offer help at this point rather than trying to do so when you've bricked it.....
As far as roms are concerned, you cant go past 'civato's FLEX roms' very stable and no issues i'm on cm10 and havent had a problem with it.....Of course it depends on what you require but I'd start with one of the flex ones.
Most peeps here have no trouble with this process, those that do, usually try things the 'normal' way, then find out they need their cpuid/sbk to get out of trouble and of course they dont have it....this makes things most difficult.... there are a few tabs with motherboard issues that have needed to be sent to acer....other than that, he only other issue you may have are driver related, check out the cpuid thread for anything driver related and lots of other background info too....theres also a zip file there that has a mini-sdk kit, to save u downloading the full android-sdk....
i think thats all i can think of at the moment, sorry for the long post and all the caps and bold text - just trying to save you alot of unnecessary grief...
Good luck with it all and remember....in this forum things are not 'normal' :laugh::laugh:
Wow, a lot of stuff to do just to flash a from huh. Lol
Sent from my A500 using xda app-developers app
Lol, as always preparation determines the success of the final outcome....and yeah with the tab 95% of yr time and energy is spent preparing!!! The actual flashing process takes only a few minutes...
Of course u could revert to hc 3.1 where everything is 'normal' i.e. one click root, flash cwm, flash rom, done....
Gosh, even hc 3.2 was locked down and unrootable....
So in the grand scheme for us to even be able to have stable ICS roms, let alone cm10 on the a50x.is.purely down to those wonderfully clever devs we have here..who were never gonna let a.locked bl, get in their way..
OK its complex I'll admit, but stock ICS is c**p and the lives of our tabs extended past wot Acer ever thought....and guys like gersma and.blackthund3r have built auto tools to make things easier
Anyways, its.well worth the
effort and is actually alot simpler to do than it is to describe how to do it...think of.trying to explain how to ride a bike and writing all those steps out....much easier to help them thru it by just getting them on the darn thing and doing it....dontcha think??

Oh, one other thing, you'll wanna back up all yr personal stuff, music, photo's and wot not especially going from one build to another, and most of the custom ROMs require a complete wipe and format of yr data partition too before install, just so u know!!

wow dibb, thank you so much for a helpful response!! Really enlightened me about how far off I was about the update process (compared to updating phones) and yet close enough to what I had to go thru for the Viewsonic GTab.
I'm currently on stock 4.0.3 rooted for A500. I have obtained my cpuid and SBK. When I go to recovery mode, I see a droid with triangle and exclamation mark. I tried flashing twrp but I still saw the same droid. I now know that I need to flash a different bootloader with recovery included.
My question is that if I flash the new bootloader which will allow me to put a custom recovery, during that process will my current ROM be removed or wiped out? If so, what do you recommend for backing up the app in the current stock ROM? Titanium Backup? BTW, I don't have an external SD card; all I'm using is the internal 8GB
Thank you for your help!!
def need external SD , it will help out alot

Yes u need the v8 bootloader to get a recovery installed...
Always check the original post of the rom you install for special instructions regarding bootloaders.....this applies to all custom Roms even stock pre rooted ones.
Yup TB to back up yr apps and data - dont restore immediately...make sure everything is stable first.
If u dont have an ext. SD card, the EUU method doesn't require one, and as slayinu said, it would make it easier if u had one especially for the update.zip methid
Im sorry...

Seems weird afterota "doesn't do anything"...did you install the drivers?? Did it give u yr cpuid/sbk you cannot do anything without this AND if u muck things up its the only thing that will get u unbricked? Are u using a micro USB cable? Do u have USB debug enabled?
If u go to the root guide in my sig you'll find d.load links and all the guides to help u install the v8....take special note of the boot.p file u need to rename or delete in /system....
For more info on getting yr cpuid/sbk see the cpuid guide in my SIG or the sticky in dev forum...

obviously..
I'm too dumb to figure this out...idk how to get my cpuid none of the ways in your "where's my cpuid"guide worked.I don't want to stay stuck on ota 4.0.3 but apparently I have to..thanks for your time and your advice,unfortunately I wasn't able to use it properly.
Well, it seems it's not just you being dumb ...
I tried the same - original OTA 4.0.3 and rooted my A500. Now tried to use the 'AfterOTA'-Tools, but getting stuck in step 3 of 4 (maybe i just need to insert a SD-Card in the Tab?).
Just got no idea, what to do now - the only thing i know is: before flashing, i need a open bootloader, but i've got no idea how to do that. The Guide linked in this posts: http://forum.xda-developers.com/showthread.php?t=1622425 is just confusing me more and more
After a reading a few times, it seems to me, that MY next step should be:
"Automated flashing tool" (STEP 5= Going into APX mode see Q&A or use A500 manager)
-1-Reboot your tablet and make sure on your tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch on.

-It will ask if you are ready (click yes if you are)

Hi voodoo, no, neither of you are being dumb!!! It CAN be a complicated procedure, we try to make our guides 'simple' but theres ALOT that can go wrong
Yes the last link you posted will flash the patched bootloader!!!
- but basically this is what SHOULD happen
Note: The only way to get a custom ICS rom on your tab is with the v8 bootloader by skrilx_cz. This must be flashed via nvFlash/apx mode.
Note:The only way to install a custom recovery like cwm or twrp etc is with v8 bootloader.
Note: You cannot use Acer Recovery Installer unless you have the v8 installed.
Note: Rom Manager does not support our Acer Tabs...please don't use it to flash 'anything'!!
OK heres an overall view of the process:
1. Install Acer and adb/fastboot drivers
2. Retrieve your CPUID...
3. ...and use it to generate your SBK
4. Download your ICS or JB rom and copy to your sd card (internal or external)
5. Enter apx mode to begin the flash!!! or use apxFlash tool
5. Use balckthund3rs apxFlash tool and follow the instructions: hint: dump and save your bct!!!
5. If using civato's manual nvFlash method - Put your tab in apx mode and run the .bat file
5. AfterOTA Tool is only for those tabs which have OTA'ed to ICS!!!
The main issues you will have with the actual flashing process itself is a partitioning error or a bct error - and both of these are easily fixed...UNLESS your tab in one of the few with a hardware fault which only a new motherboard can remedy
Once you get the big white "PASS" on your tab, boot straight to your new custom recovery, do the FULL WIPES and flash your new rom....DONE!!!
Well ... i now used AfterOTA - but not in a virtual machine - now just natively installed on my macbook via bootcamp (windows). Worked. I now have a V8-Bootloader (the tab shows me this when iam booting it up).
Whats the next step to flash a new ROM? Iam ready to do that? Or is there any other step needed by now?
Regards, Tom
Edit:
I now just tried flashing a custom rom - so i copied the *.zip to my USB-Stick (FAT32) - because i read, i can use an USB-Stick as an micro-sd card.
Tried booting into recovery-kernel - worked for me, but the only thing i can see: a lying android with an red sign ("!").
Did i something wrong?
Oh dear....if u had a stock rom on there then its overwritten
your newly flashed recovery....you need to delete or rename
the "boot.p file" in /system..then reflash the v8...
The very next step should be to enter recovery and flash your
desired rom....
So, it now just works everything.
Used Acer Recovery-Manager to re-flash the recovery - worked fine for me.
But: i tried several 4.1 and 4.2-ROMS ... is it correct, that there's no Google Marketplace anymore on 4.1 and 4.2?
My colleague brought his stock A500 to me in a bricked condition last week.
I need a way to restore it. If I try to do a wipe it will say bootloader error if i try the recovery the droid falls down with the red sign with the exclamation mark.
This tablet has never been rooted, my colleague is not in to such things, it's lived its life with ordinary acer otas and the occational very young human (5 year old) trial wich it has survived.
He has installed all the OTAs he ever got on the tablet and this is in Sweden so it would probably be a 4.0.3 acer stock on it now.
I'm guessing it has died during a OTA or something. if i turn it on it will sit at the acer logo indefinitly.
I Bricked my A500 during a rooting atempt resulting in me needed to flash a stock rom to get it working again, but i cant find the thread i read to un-brick my A500.
Please Help!

Well that thread seems to hold all i need, although i can't do a full wipe. when i do the flipswitch wipe procedure it halts with bootloader error
Im hoping to just be able to flash the stock rom from the link you gave me. Is it entirely necessary to do the wipe prior to flash? can i wipe it afterwards?

we're assuming the tab is full stock and currently on ICS...
and we're assuming he never tried to 'fix' his tab by flashing one thing or another...
the bootloader error worries me...what exactly does it say...
Yes the wipes are really important!! and not being able to use the button method to do so is concerning...
what happens with the Over The Air (OTA) updates is its just that...an update...it leaves all your settings/data intact. When you OTA from one build to another, like Gingerbread 3.0 to Honeycomb 3.1/2 and then to ICS 4.0 - you drag all your apps and settings with you and of course some things that work with 3.2 will not work under ICS....fjor instance, lots of folk had trouble with wifi disconnects, once they got to ICS - or they had apps force closing and other 'glitches'. This is why everyone tells you to do the wipes - as this fixes these things! In the case of stock ICS my gmail would f/c all the time no matter how many times I wiped/formatted....So for a smooth running tab - flash a custom rom!!!!!!
But getting back to you...
From that link i gave you...download the 3.1_Full.zip....its decrypted so just extract it and get the "update.zip" from it..
This "update.zip" is not an incremental "update" but the full stock rom....
once installed you'll be on GB you will need to root it with iconia root and then use acer recovery installer to flash cwm....(get these from the playstore)
do a backup or adb devices so you can get your CPUID....this is important...if anything goes wrong at any stage this is the only thing that will get you unbricked....see the cpuid link in my sig for more on this, please take the time to read it, even if it doesnt make much sense to you, read it anyway....
AFTER you have retrieved your cpuid, you can nvflash the patched bootloader/recovery pkg which means you are able to flash ICS/JB custom roms
they cannot be flashed via cwm like normal...you must use nvFlash to do it....
OR
take the OTA route to ICS...this takes a bit of time...I did it last week and it was a good 6-7 hours to go from GB to ICS
there are pre-rooted stock roms if you wanna stay stock see civato's stock rom thread for that here http://forum.xda-developers.com/showthread.php?t=1633907

I am in a similar situation. Push the power button and it goes to a screen with white acer on black and stays there. Totally stock ICS, no root. I tried the update.zip thing and after automatically rebooting it says "Boot verified failed...". I don't have my cpuid, or have installed previously CWM or anything like that. I can get into APX mode. This guy here: http://forum.xda-developers.com/showthread.php?t=1751978 could only get into APX with no cpuid as well, but i don't understand all of the ubuntuu and command line stuff. I would love for someone to be able to walk a dummy like me through this mess. Thanks for any help.
if u got boot verified fail error you need nvFlash to repair that....as u know, with nvflash you need yr cpuid....wot about usbdeview? if you've never plugged yr tab into yr PC - then it won't work and the ONLY other way is Linux....
might be best to start yr own thread with a descriptive title, not just a help I'm bricked no uid, thread there are hundreds of those....the more effort u put into the title the more likely you will attract the attention of someone who can actually help...and remember you just don't need a bit of help but a blow by blow description of what to do and how....this will be very time consuming....at the very least get ubuntu installed, maybe just try a few things, anything to show you are capable of at least giving it a go yourself..
there are others who would like 2 know how to do this as well...having a specific thread of its own would be great
good luck

Actually, I have connected it to my PC before. Only for transferring media though. If I've done that, is the some way to retrieve my cpuid from the PC?
yup...usbdeview.zip see the bottom of the OP in the cpuid guide in my sig
Thanks alot for your help. I used usbdeview and got my cpuid. Now I should use nvflash? Know where a good step by step is for that one?
you could try the one in my sig??

Right. Sorry, I didn't notice that before. Thanks again for your direction.
"To install one of these roms you will need a custom recovery and to get that you must flash the patched bootloader FIRSt - once its patched you can install a recovery any old way you like"
Looking at that guide, would you please tell me what a custom recovery is and how to get one? Btw, I don't plan to do a custom ROM yet, I just want to get the damn thing working first. Was thinking of using the HC EUUs from the firmware files list. However there are two files, a .rar and a .exe listed. Which do i use?

The .rar EUU is for an A500, the .exe is for the A501, which do you have?
I've got the a500. However, I decided to go with a custom ICS rom after all. I managed to put a new bootloader and custom recovery on using the a500apx flash tool. That part went fine. I flashed this rom:
Acer_AV041_A500_1.054.00_WW_GEN1-FULL-ROOT (original odex)
and that appeared to go well according to twrp, but after rebooting, it just shows the bootloader again and stops there. Not sure what i did wrong.
I renamed the rom update.zip. Should i not have done that?
well congrats for getting thru the flash process with no probs!!!
as far as renaming to update.zip that was not such a good move...hopefully things havent been screwed up too much
just go back into recovery and do a FULL wipe/format
then to flash use the option "install from zip file" not sure where that is in TWRP but it will have one
Okay. I will reflash the rom after completely wiping again. Thanks.
On a different note, why do roms require particular bootloaders?
Also different, how do you like your SGS3? If i can manage to fix this thing, perhaps I'll root my phone...

The stock ICS BL is encrypted - more or less - the only way to 'flash' a recovery or rom is to have the "key" that "unlocks" - it more or less - if you dont use the right key then the OS will not boot - the 'key' is based on your cpuid which is why everyone is forever telling you to save it somewhere safe....
Also different, how do you like your SGS3? If i can manage to fix this thing, perhaps I'll root my phone...

I enjoy the big screen, took awhile to get used to it in my hand, kept dropping it....then I ran it over with my 44tonne truck after 3 days and munted it!!!!
I have a case for it now, and its gr8 - I havent installed a rom on it yet...the forums over there are jampacked and I have no idea what I'm doing, lol - its the first android device I've had that I've left stock for so long...but it does what I want...the camera is awesome -burst mode is the bomb - BUT do I think it was worth the money???? Still on the fence about that one.....
Ouch. Sorry to read about running over your phone. That would kill me. I really like my SGS3. I think I'll look into rooting it just to be able to back it up and get rid of the bloatware. I did that on my Captivate and prior to today, thats all I've ever done modding wise to an android device.
So, I managed to get my tab up and running again. Yay! I reflashed the rom w/out changing the name and worked like a charm. Now If only I knew why this happened in the first place... Thanks for all your help.

yeh sometimes happens with the tab for some reason - thank your lucky stars it didn't get stuck in apx mode...if that happens its normally a hardware fault so theres not alot u can do...I'm just pleased you got sorted without too much drama and it was as easy as reflashing the zip....so now you have the v8 BL - you're gold!!!

we're assuming the tab is full stock and currently on ICS...
and we're assuming he never tried to 'fix' his tab by flashing one thing or another...
the bootloader error worries me...what exactly does it say...
Yes the wipes are really important!! and not being able to use the button method to do so is concerning...
what happens with the Over The Air (OTA) updates is its just that...an update...it leaves all your settings/data intact. When you OTA from one build to another, like Gingerbread 3.0 to Honeycomb 3.1/2 and then to ICS 4.0 - you drag all your apps and settings with you and of course some things that work with 3.2 will not work under ICS....fjor instance, lots of folk had trouble with wifi disconnects, once they got to ICS - or they had apps force closing and other 'glitches'. This is why everyone tells you to do the wipes - as this fixes these things! In the case of stock ICS my gmail would f/c all the time no matter how many times I wiped/formatted....So for a smooth running tab - flash a custom rom!!!!!!
But getting back to you...
From that link i gave you...download the 3.1_Full.zip....its decrypted so just extract it and get the "update.zip" from it..
This "update.zip" is not an incremental "update" but the full stock rom....
once installed you'll be on GB you will need to root it with iconia root and then use acer recovery installer to flash cwm....(get these from the playstore)
do a backup or adb devices so you can get your CPUID....this is important...if anything goes wrong at any stage this is the only thing that will get you unbricked....see the cpuid link in my sig for more on this, please take the time to read it, even if it doesnt make much sense to you, read it anyway....
AFTER you have retrieved your cpuid, you can nvflash the patched bootloader/recovery pkg which means you are able to flash ICS/JB custom roms
they cannot be flashed via cwm like normal...you must use nvFlash to do it....
OR
take the OTA route to ICS...this takes a bit of time...I did it last week and it was a good 6-7 hours to go from GB to ICS
there are pre-rooted stock roms if you wanna stay stock see civato's stock rom thread for that here http://forum.xda-developers.com/showthread.php?t=1633907

I googled your error - the consensus from what I read is a corrupt OS due to running OTA updates...
Some had luck with rebooting. Others had to send it to Acer.
Did you run the update.zip? so what happens when you run the update.zip
Are you able to get into "apx mode"? If you can, hook up to your PC and see if your tab is recognised as an "apx device" - check "Hardware, Printers in win7"
Thats all I can suggest atm - if your tab does get into apx mode OK then you can find your cpuid by running Linux -
Maybe ask the guy if he's ever had the tab hooked up to his PC like to transfer files and stuff - get him to download "USBdeview" to his PC -
this will show every single device thats ever been connected to the PC and it will show the "cpuid"...
Even if we do get the uid theres no guarantee it will fix the bootloader error - but we may as well explore all the options we can....
dibb_nz said:
USBDeview will only work when you have previously plugged your tab into the PC WHILE you were running HC Rom and BL
1. If you haven't plugged your tab into this pc before, do so now, before you run the program. HC ROM/BL ONLY
1a. Run the exe and you will be presented with a window of all the USB devices you have ever plugged into your computer.
2. Click on "VendorID" column along the top to sort them
3. Look for the number "0502" under Vendor ID AND "3325" Product ID
4. In the serial number column will be a 15-digit number this is your device ID.
5. Write the number down and put a 0 in front of it and now you have your CPU ID!!!

Ok, here is what i have , I have a IConia a500 rooted with, link for forum and files, using ICS Root
(came with 3.1, ran all the iconia updates, to 4.0)
everything went fine, now... i am familiar with flashing roms, i have had a few android phones and have rooted them, and flashed custom roms on them. that is what i want to do with this, after doing over 4 hrs of reading, I have confused the crap out of myself. there is a lot of talk about things that i dont know much about..
-CPUID's
-ICS recoverys (bootloaders?)
Basically, all i want to do is add the CM Jelly time mod, but im not 100% on how i go abouts that? what do i need? i have the files and gapps, etc., i know i need a full wipe, but what recovery do i use? CWM? do i temp flash it or, pernament? after watching a few videos, i still dont think im ready, i diont want to brick this thing. i just want it to work with that rom. thanks any help and clarity is severly appriciated!
j
1. get yr cpuid and save it multiple places open a file explorer and go to /sys/firmware/fuse/acer_cpuid
2. then go to /system and rename/delete recovery-from-boot.p file - this will prevent your custom recovery being overwritten with the stock recovery.
3. have your custom rom on yr ext SD card, ready to flash ONCE you've flashed the unlocked bootloader
4.To flash the v8 bootloader you need to use nvFlash and there are a couple ways if going about that...
a) manually by using the guide in the OP of civato's BL thread
b) using one of the auto tools like afterOTA or apxFlash - links also in that same post...
c) you'll also get to pick a custom recovery and it will be flashed at the same time - cwm 1.7.3 is recommended until you're running stable
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
5) once flashed, boot straight to recovery
6) Do a nandroid backup then the wipes
7) Flash the rom
8) Reboot to recovery and wipe again
9) Job Done!
notes:
Everything you need to do this is in civato's BL OP - sorry can't post the link but its stickied in the Dev Forum
the afterOTA tool,
- saves all yr uid details etc in a txt file
- flashes v3 bootloader -
- it also installs the needed drivers too
- its pretty good at what it does...
seems some are having wifi issues with jellytime but the dev is working on this
you've done the right thing by asking questions before attempting anything, wish everyone was like you...if my post isn't clear then please let me know....for those of us used to the way things work with our Acer, its hard to remember how difficult it seemed when we were new!!
good luck

ok, thanks !
i have used the afterOTA and it would let me select the recovery i wanted to boot, is this permanent or temp? right now on my phone its the cwm, but i remember on my Nexus S, they recomended just pushing it, that way it was super hard to brick.. basically i just need to know if i need to run the afterOTA tool everytime i wanna boot into recovery? thats why i like my CM 10 for my Galaxy Nexus, i can choose to boot into it,
I think the hardest part of these simple tasks, is that there a 20 steps to something totally new, I used to unlock iphones for a living, I never knew what i was doing exactly, i had a rough idea, but i did know how to cut and paste. even going from my NS to GN its always been a few hrs to root/unlock, Being familiar with a lot of the steps, theres more with this tablet! EI, CPUID, APX? tons of warnings! the other things are the abriviations, they can be confusing.. soo
this is the only thing i didnt understand, does the OP dumb it down, or can you??
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
what is sbk, and why do i need it?
thanks again, i really appriciate it!
also, what is a LEAK? leaked rom?

no m8, once you've 'flashed' via the tools its permanent -
there are flashable zips around (for recovery) but again, you need the unlocked bootloader first....once you have it then you can flash anything, anyhow you like. Even Acer Recovery Installer will work fine and you can flash a rom from there too, though that may require the paid version from memory.
the only time you will 'lose' the unlocked bootloader/recovery is if you need to rollback to HC - specifically 3.2 -

yeh I'm hearing you - this thread is a perfect example!!! I'd love to be able to say...root it, then flash cwm and the unlocked bootloader IF you want it, lol

sbk = secure boot key....as you've discovered 'root' just isnt enough to flash anything...to flash anything you need nvididas nvFlash program PLUS the key to unlock the encryption which is hardwired into the ROM of the memory chip itself -(haahhhaa I think thats right) - The CPUID is unique to every tab (and this too may be hardwired into the chip as well) the sbk is a hex number based on the uid. there are a couple of generators around to do this for you, blackthund3er has one and so does vache....you've used afterOTA so this does the genration for you automatically - you can see it in the text file you saved
thanks again, i really appriciate it!

yeh back in the day before acer released ics, 'someone' got hold of a leaked ics version, and this is where alot of the work was done on unlocking the bootloader...by the time acer got round to releasing ics - we had a more stable version than they ever had
So now you're unlocked and rooted, have all your ID's backed up and done a nandroid you can quite happily flash to your hearts content!!!!:good::good::good:

standard tab choose first option...keep an eye on the status bar while its flashing..should not take longer than 10mins.
You must then boot straight to recovery and flash yr rom from yr USB key
don't have to worry bout apx mode but yr tab should display.either Acer apx mode.or Acer download.mode at stage 3 of 4 in tool status bar.
if u.muck.up you'll learn all u ever wanted.to know about apx.mode

DON'T FLASH THE FIRST ONE!!!!!!!

Looking to do a stock install of 3.2 on A501
blackthund3r said:
LIST OF FILES
Please note that none of these files are rooted and/or tweaked! They are stock Android ROMs from Acer and designed for stock recovery!
Flashing them will remove custom recovery and/or custom bootloader! You will be fully stock! Update zips may not install if you have modified your device in any way. If unsure use a full package! You need an EUU package only if your device is bricked as it will be completely wiped clean in the process!

I am looking for the 3G version the 3.2 stock ROM to do a fresh install on my A501
The link from Vache seems dead.. can anyone please help to provide that particular ROM?

Best to just get stock ICS. Why are you password locked? Is the device stolen? I can easily help you get past it but I'm not sure whether I should.

Thanks blackthunder. It's our personal device, my wife set the password some time back and is sure she hasn't forgotten but for some reason it's not being accepted. We can't figure out why! I have the original receipt and box etc in case anyone's interested!
I tried the stock ICS Rom by naming it update.zip and rebooting into recovery, but that gets stuck at the Android guy logo immediately. Also tried 3.2 before that via a link from this page, and that seems to work until the progress bar hits about 80%. Then it just reboots back to the dreaded locked screen. From what I understand I can only do a reinstall of the same ROM version that's currently installed? We have a password lock on it, and not pattern. Would highly appreciate any help. . Really want this thing to start working again. It's practically new [emoji20]
Guys any idea? Really desperate here. Thanks in advance!!

Your beat bet is using an EUUs package to wipe the tablet and reset back to 3.0.1 then use Flash Tool to get CWM or TWRP + a decent ROM

To install EUUs, is it the same process; rebooting with power+volume and flashing via SD card? What version EUUs do you think I need, currently I have 3.2 installed. Is there a guide for above?... will be a lot of help. Many thanks

Actually, even easier.....use the APX Flash Tool to get yourself a CWM Image (you'll need your SBK....there's a fair few guides on obtaining this) then do a wipe data/factory reset within CWM.
From there it's fairly easy to side load the latest Acer ROM.
Thanks. I'll try it out over the weekend! Appreciate your help!
God morning! For the apx tool, I'm not sure if USB debugging option is selected, never ticked that myself consciously. Is it OK to go ahead?
Tried using the apx tool after downloading the Acer USB drivers and in short no luck.
Had to go the manual route for flashing since I don't have USB debugging enabled.
Tried two packages, one honeycomb bundle 6 and then also tried a later one for ICS.
It goes thru the motions enters APX mode with confirmation as well on the tab screen, without any hiccups right to the end. But then reboots to the old dastardly lock screen asking for password!
Any ideas? Already backed up using mobo app so am OK to wipe clean and start anew.

Options for upgrading an Acer A500: Acer_A500_4.010.15_COM_GEN1
OK, heres a totally noob question. I have an Acer A500 I bought used. It has been rooted apparently. Has the ClockWorkMod bootloader installed, v5.0.
My question is, what are my options to upgrade this tablet and is there a thread with instructions on which firmware files to use, how far can I go with upgrading the A500 (ICS?). Not really looking to trick it out and go the whole mod route, would be happy with stock firmware, just looking to make it a little more up to date and, above all _stable_! The main issue I have with it now is the wifi craps out every month or so and I have to do a refresh and wipe all info and start over.
I used to get prompted to install a system update, and every time, it would fail with the dead Android dude on his back....so sad. Now, it just tells me, "Network Coverage is poor, please move to a location with better coverage". I am sitting right beside my router...
Here are the relevant specs:
Model number: A500
Build number: Acer_A500_4.010.15_COM_GEN1
Kernel version: 2.6.36.3
If you need any other info in order to help, just let me know.
Thank you very much in advance for any advice!!
