I'm trying to restore my Acer Iconia A500 back to the stock/ original ROM so that I can grab the official update in July. Is there any way to do that? I really like the custom ROMS, I just want to revert to see what it was like.

And, of course you made a backup via clockworkmod???? eh?
Why are so many not making backups of their tabs before installing unknown software?
There's lots of threads about this in the forums with instructions already. And this belongs in the General forum, not development.
Yes I'd also be interested in this. I have the droid x so when ever I want to revert to factory settings theirs a program on the computer (rsd lite) I use to revert it. So I almost never backup my roms. Now on my iconia they don't have such program. At least that I know of. So I flashed a rom on my iconia and didn't make a backup of my current one. I tried fixing it by flashing stock_acer a500.zip I thing by dexter don't quote me on that one. But it was the emea version so now its stock european and I live in america. Help is apreciated.
I'm a flashing person that has flashed many times on my phones. I forgot to make a nandroid backup of my original rom myself...so I'm not judging. I would say, flash honeyvillian, as its the closest thing to stock I've seen.
But, if your already flashing, I wouldn't want to grab the official anything...someone will post it once it comes out.

I want to flash it to the latest stock. So when ota 3.1 is released, I could rest assure knowing that my device would get updates ota.

because we are impatient and stupid
I am running to get someone with a tablet of my country to get back the STOCK ROM in case of... I am going to see if I can deal with the shop to root and recovery on SD Card the stock rom so I will be able to have the stock rom...
For USA version 1.104.02, Check out this post.. You'll probably want to skip flashing the stock recovery until you know the system will boot normally.. So from this post, run itsmagic, flash boot, flexrom and system, in that order. Preferable from an adb connection. The tablet will freeze while flashing system. Give at least 5 mintues to make sure it's complete.
You may need to do a data wipe if it bootloops (that's why you should skip flashing recovery). Once it's booting normally, you can flash the stock recovery if you want.
Alternatively, you should be able to replace the files in dexter's stock update zip with these files. But I haven't looked at that zip, so I don't know if system is an image file or a archive file.
Thanks for the replies quick question though. How do in run its magic is their a command for ADB or do I acess it via clockwork recovery?

You download it from the itsmagic thread in the development form and follow the directions in that thread.

I too would like to restore to the 3.0.1 stock rom, however my backup of the stock rom got corrupted somehow. I know it had to be something I done, but know not what it was I did. Any help would be much appreciated. Or would it be a better idea to flash the 3.1 leak?
So first of all my tablet is brand new and not rooted and I don't want to root it.
When I got it I could update it instantly from 3.0.whateverwastheversionatthetime to android 3.2 (build 7.006.01_COM_GEN1) but it won't go from there to 3.2.1 which I hear is available for my location (France) The update tool tells me that my firmware is up to date.
I've tried a factory reset as advised by Acer customer care services but it wouldn't change. Also no matter what I do (empty cache etc.) the market won't update to Google Play Store and I think the two issues are related.
So I have two (or rather 3) questions:
1) Does anyone know a way around to force the update? (I doubt it's possible but hey "l'espoir fait vivre")
2) If not can I install a stock ROM without root and NOT compromise the warranty?
3) Where can I get such a ROM? I have searched here and here but 3.2.1 is not on the first thread and the links on the second thread are broken, plus I want to make sure that the ROM is the proper one for my region and that comes the ICS OTA update I will have no troubles doing the update.
Thanks in advance to those who will answer.

1) No you cannot force an OTA
2) It depends - others have reported returning there acer with no probs -, i think someone has even returned it rooted and been ok. These things are fairly bulletproof, and really hard to 'brick'. As long as you can read, follow a few steps you shouldnt have any probs. The worse thing you can do is try 2 or 3 different methods all at once because something isnt working right. You're best to pick one and stick with it, if you have probs ask for help in the thread you got the rom from or start your own like you have here
3) The update.zip method from the first link you posted "should" work. Did you "decrypt" the file you downloaded before extracting the update.zip??
You could try timmyDeans v4 method- it will install a stock 3.2.1, it is rooted but you can remove root using the tools he provides. Beware though this will wipe all data so backup anything essential.
The update.zip method will leave your data and settings intact
As always the choice is yours, there are some really excellent custom roms out there - I enjoy the best of both worlds with a backup of my trusty stock 3.2.1, I flash to my hearts content knowing I can always go back to it when the OTA update is out!!! Oh the joys of root priveleges
Thanks for your input, I'll make sure to try all this when I get back from work. I've a few additional questions:
1) If I install a custom rom, will the OTA work from this ROM or, comes the OTA, will I have to restore my actual Stock rom and then proceed with the OTA?
2) I haven't tried the rom on the first link I gave because it is modified and I was searching for the original, pristine, untouched stock ROM for 3.2.1
I've seen such roms around here on xda for 3.2 but none for 3.2.1, if anyone stumbles upon one please let me know.
3) Since I'm still looking for a pristine ROM before trying anything else, I have a friend whose tablet (same brand and model) safely updated to 3.2.1, is there a way to make a rom from is gear? If yes, how to?
4) (related to 3) how can I backup my actual ROM, do I have to be a root user to do so?
THX again!

1. Typically, most people do not take OTA's when running a custom rom, as basically the OTA installs a totally fresh factory Rom. This is true with the 3.2.1 update, which contains a new bootloader. Usually, this means you lose root, and Recovery, then stuck with downgrading to get these things back.
Timmy Deans root tool supposedly maintains a back door method, which s supposed to protect root, in case of an OTA. No, I haven't used this method, as I run my own 501 roms.
2. Vache has a thread "full package and updates" in the 500 Dev forum. There are several factory Roms and Updates. You'll have to look. Chances are, he may not have the specific Com Gen version you want, but probably one close enough.
3. If your friend can get adb running, you can pull a "system dump", which will dump all files/folders in the system folder. The boot.img would be nice to get, but you can probably use the current one you have. Unfortunately, he already rebooted, so you probably can't get the original full update file. If he's rooted, you can use an app called Rom Factory, to get most of what you need. It's always a good time to become familiar with ADB.
4. Well, you can back it up internally, but it's sort of useless if you can't get into your OS You will need to Root, and install a custom recovery to keep your backup externally.

ok, as Moscow has pointed out, in vaches thread not all roms are listed. My stock roms (1.016.01 and 1.139.04) for instance weren't - so I spent the last hour or two trying the "EUU gen1" listed at the bottom of the page. Well, it actually worked!! It gave me an OTA to 1.139.04 straight away. After that installed i got the 4.010.40 to 3.2 and then the next 2 for 3.2.1 - 7.006.03 and 7.014.15. So its given me the correct updates for my country AND kept my data and settings too.
SO, since you're on a Gen1 Rom this should work for you too, but still no gaurantee you will get the OTA to 3.2.1, no harm in trying though
btw timmydeans method is a gen2 rom so you can rule that out...
---------- Post added at 11:25 PM ---------- Previous post was at 11:16 PM ----------
just came across this link for an update to stock 3.2.1 build 7.014.14 here - orignal thread here but you need cwm to install it....
unless you can make it into an update.zip???
but thats way outta my league,
moscow may be able to suggest something though
Thank you very much, your answers help a lot! Just a few precisions and I'll stop being a pain in the ass!

==> @ Moscow, when you say "lose recovery" does it mean I lose the green thingy with gears when I start with volume down and power pressed/ and when I reset to factory settings?
==> @dibb_nz your method is the closest to what I'm looking for, I also hope it will give me the correct updates for my country and since Vache is a fellow countryman it might just be ok.
Anyways thanks again, I'll give a thorough look to all of your solutions and try and do a few things tomorrow afternoon. I'll keep you posted in case this thread interests anyone else.

No, what I meant to say, is when you run a rooted "custom" Rom, and use a "custom" recovery such as RA Recovery or CWM, getting an OTA update, usually wipes that out, and installs the factory bootloader. Your factory recovery....cough cough.... will still be there.
If you are only concerned about stock factory, then don't worry about it. You;re ok. Your factory/stock recovery will be just fine
The reason we root and install custom recoveries, is so we can do 3 primary things.
1. Flash a custom rom
2. Create a complete system backup to our external SD card.
3. Get rid of pre-installed useless apps.
There are other things we can do with it, but these are the primary reasons.
When you have a default factory stock system, the only protection you have, is a factory reset (hope it works), and a couple other methods which require a touch more knowledge.
Anyhow, don't worry about your factory recovery. It's just fine.
1) Just for the sake of knowledge what's the difference between GEN_1 and GEN_2? (and GEN3 and CUS7 and EMEA_TMLP)?
2) @Dibb_nz when you tried with the stock rom from Vache, was it because you encountered the same no FOTA update problem as I did? Or just to try...?
3) Something's still unclear to me after browsing through the forums: If I get an unmodified stock ROM can I flash it with the stock recovery? (so without rooting) Or do I need CWM (so root is needed)
4) What's EUU? (on Vache's thread some roms are listed as EUU)

1. The Gen's usually signify regional based roms. More specifically language support, sometimes a wifi tweak, and maybe a couple other things. Mostly though, ComGen1's are for the US and probably canada, and offer about 12 different languages. TMPL is for East Europe mostly, with polish as the default language. All roms contain the english language as far as I know.
3. You basically can't install a full rom on an unrooted tablet without CWM or RA Recovery. You will have to run the update (decrypt the file, remove the update.zip)
4. EUU is a pc based install. Plug in the USB, set your tab to APX mode and run the EUU.
If you did the root, and install a custom recovery, then you could run just about all the full roms. Your custom recovery would be overwritten, and you would lose root access. You would have a stock tablet with the version rom you selected.
You can always wait a week or so. Am sure if the update has been pushed to your country, it's just a matter of time till you get it. It's common for the update process for specific roms, to get fully done in 2-3 weeks. It took well over a week just for users in california to mostly start getting updates.
Well the official release date for the ICS FOTA in France is May 3rd, so I'll wait until then but having other options and the know-how to take actions is always a good basis. (plus I'm really not the patient type ^^)
Stupid question but I'm guessing EUU needs root too?
and also APX means rebooting while holding power and volume - right?

I tried the EUU just to see if it would keep me on my regions OTA upgrade path.
Sometimes you can have probs OTA'ing if you aren't using the rom from your region.
But in this case it gave me the correct OTA's.
APX is Acer Download mode, where the OTA upgrades are flashed - this EUU will do it via your PC. Button push method (power/reset button) not required.
No, the EUU does not need root which is why I tried it out for you
You will need to be on 3.2.1 before you will receive the ICS update
I used this EUU from vaches thread -
EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
late for work will check back later
That's really helpful thanks I'm downloading the same EUU you used and will try it today or tomorrow depending on how much time I have, will keep you posted!
Ok so I did the EUU install and it worked fine, the tablet then allowed me to upgrade to 3.01 and then 3.1 then 3.2 via FOTA without any problem. But once I reached 3.2, the update tool informs me that there's no update available and my gear is up to date
So my guess is Acer France are not pushing the 3.2.1 FOTA update anymore...
Any other explanation?

Glad to hear u got thru the EUU process OK, not so great u still can't ota to 3.2.1
Others have reported similar issues not sure if/how they were ever resolved. As moscow posted earlier,ota,s are not made available to all users in all regions, all at once, so it may be just a matter of waiting for the next "push cycle" to roll round.
At least you know you can always get back to stock if you ever decide to root and go custom There no direct root method for 3.2, just use that same euu to get back to 3.1 and use iconia root and Acer recovery installer from the market and you're ready to flash your rom of choice
Pls post back if u do get the ota - best of luck
rgds Donna
Yeah I was just browsing the XDA forums, contemplating the idea to rollback and root and then installing this
I wonder if it's worth waiting for the OTA... as for what you said about waiting for the next "push cycle" I've been waiting since I got the tablet and the update hasn't come yet, which is strange because the ICS update is due on May 3rd in France and I'd guess they'd have everyone up to date and ready for the update by now!
Rooting seems pretty straightforward and much easier than what it was on my Samsung Galaxy Spica: I found this
, a file called iconiaroot.apk on the sdcard aswell, rebooting your tablet while pushing the volume down button so its starts flashing the buggy honeycomb version.
Then start up the tablet again, rush to the market, download some file manager, with that filemanager explore your sdcard, and install the iconiaroot.apk file, once thats done, rush back to the market and download and install acer recovery installer. At that point you will have CWM (clockworkmod) installed.

is that all there is to it?
In any case I'll keep you posted just so it can help anyone with the same issue!
alsoe FYI and just for the anecdote: the reason I'm so cautious about everything and scared ****less of rooting is that the tablet is a present from my girlfriend for my 30th birthday, and she'll hang me with my guts if I brick it.
Ok I rooted and flashed the above-mentioned rom and it works! I'm now under 3.2.1!
Thanks to everyone who helped me! When the ICS update comes I will post here to signal how the FOTA went.
Thanks again!
Lol, good onya for taking the plunge! Yeh acer recovery installer is brilliant, along with iconia root, makes the whole process stress free.
Will be interesting to see if you get a notification for ICS OTA with that rom.
Can always flash one of the leaks if u get impatient??
Glad everything's worked out and yr g/f still talking 2 u
rgds Donna
thx! I will post here when/if I get the OTA. and my love life is safe thanksnto iconia root
okay so the ota has been rolling for over a week and a half now and still nothing for me

Oh that would be awesome! Are you rooted? Let me find the commands in the meantime, I read somewhere it's a simple one command in terminal to extract the recovery partition into a file on sd card...
WHAT AN ORDEAL !!!!
But in the end: SUCCESS!
I managed to get my tab updated with the Verizon OTA update.
The problem is definitely CWM !!! A rude awakening is in store for everyone with the P6800 CWM installed, because it a) fails to verify the checksum of OTA files correctly on the i815, b) it thinks the tablet is a P6800, so the OTA file fails to run if it assert checks for "SCH-i815" hardware AND lastly c) modem updates don't work because the device /dev/cdma_update doesn't exist, so the modem.bin firmware_update call fails !!!
In short, I had to fumble the OTA file apart and do the update manually in two runs:
First file, kick the checksum, hardware check and modem update out, then manually run the ZIP through CWM. The zip subsequently (LUCKILY) updated the stock recovery and overwrote CWM with a new fresh stock recovery.
Second file had everything kicked out BUT the modem udpate and LTE patch, so with the STOCK recovery this file ran through just fine, updated the modem and then applied the LTE delta patch.
Phew!!!
Of course I had to manually restore root after the update, had backed up with voodoo, auto restore failed, so terminal and hacking it was...
Now I have the tab running on clean stock FD01, baseband and LTE FD01, rooted and stock recovery.
No more CWM, no more "hacking" with the ROM until some dev finally releases a "correct" CWM and at least ANY factory ODIN image is available to bring the tab back to stock if needed!!!
Kinda sick of the non-support for this tab. So much going on for the Galaxy Note and pretty much every other device. I'm starting to regret having bought this "special" Verizon version
Awesome find and great to know for whenever ics does come out. Could you please post the recovery img you got?

OK after getting so many responses I decided to just post everything here in hopes that it will help others, too:
All files are here:
http://www.mywo.org:88/XDA/sch-i815/index.php
Step by step procedure to update the Verizon Tab from ..FA02 to ..FD01 build IF YOU ARE stuck with CWM installed on your tab and the original OTA fails with errors:
Upload the SCH-I815_FA02c_To_FD01.1.zip to the INTERNAL(!) SD card. This is important because CWM contains a bug that will only allow you to install from ZIPs stored on the INTERNAL SD storage.
Upload the SCH-I815_FA02c_To_FD01.2.zip to the EXTERNAL(!) (micro SD) card. This is important, because after the factory recovery is restored, it will correctly (and only) look for ZIPs on the EXTERNAL card.
Best way just copy both files to both locations
Fire up CWM and do "install from ZIP" and select SCH-I815_FA02c_To_FD01.1.zip
It should run (takes a while) and eventually tell you all is done. BOOT the tab. It should boot fine but in system it will show the new Android build FD01 but the baseband (radio) will still be the "old" one.
Now press and hold power and vol up again until you see the default Samsung recovery menu. Choose install from ZIP and select SCH-I815_FA02c_To_FD01.2.zip. This will now upgrade the baseband only. When done, reboot and enjoy being back on the "factory upgrade path" with the tab.
I hope someone more savvy than me can "fix" CWM to work properly with VZW tabs (accept the checksum, not fail the check for "SCH-i815" and provide the correct /dev file links for radio upgrades). Until then, I recommend just leaving the tab as-is and not tinkering with the ROM. Not that there is any custom ROM available anyway :-(
I also pulled the NEW factory recovery image FD01_recovery.img with the following command:
dd if=/dev/block/mmcblk0p6 of=/sdcard/FD01_recovery.img bs=4096
So in case anyone with a botched recovery wants to restore factory (Samsung 3e) recovery. This was actually the reason I had to go through all this... There is NO factory recovery image ANYWHERE to be found. I can't believe that I should be the first one ever to post one?? Anyway, hope it will help
I'm still quite new here, so I do really appreciate every click on that "thanks" button
P.S. for tinkerers and devs I also uploaded the original, untouched OTA file (0559c0e4e08e.update_SCH-I815_FA02c_To_FD01.bin) as it came from Samsung or Verizon or whatever and ended up in the /cache partition.
THANK YOU!
Electron,
You sir, are a BOSS! Thank you so very much for doing the work, and sharing it. You just made things one hell of a lot easier on me, and anyone else that follows.
Regards,
-Rob
Also want to say thanks. You rock, dude. I wouldn't have known how to revert **** on my own.
Also, I feel like we need a sticky or something for sch-i815 owners to go to for device specific stuffs, especially since there is little knowledge/info out for this device.

You're in luck! You don't need to go through the whole ordeal because you do NOT have CWM! You can just update the regular intended way. Go into settings, about phone and then click check for system updates. If it presents you the OTA update, just do it the regular way.
My complicated "hack" is only necessary if you DO HAVE CWM installed.
Im sorry I did not explain well what my issue is.
I do not have CWM installed, however i did delete a few appilcations using titanium backup. This causes updates to not take. I would really like to just take it back to factory and start over (this time with less stupidity on my part)
I of course would assume that once its at factory i can then install updates again.
Right now when i try i get the "!" droid sign and a reboot

Hey
OK unless someone can tell us how to "make" an ODIN flashable ROM for you, here is what I would do (and please don't get scared because it sounds a bit convoluted).
First, you need to be rooted. This is obviously the case.
IMPORTANT since you don't have CWM installed yet, SAVE your factory restore.img before proceeding, this saves you a lot of hassle later!
Open the android terminal, type su (accept the prompt) and then type (or copy/paste)
dd if=/dev/block/mmcblk0p6 of=/mnt/sdcard/factory_recovery.img bs=4096
Check that you have a "factory_recovery.img" file on your sd card now it should be about 8M big.
Now you're safe to install CWM from the forum, look for the other thread(s) where this is being discussed and follow the instructions for the P6800 "international" version with 3G. CWM Thread here:
http://forum.xda-developers.com/showthread.php?t=1613638&highlight=cwm&page=3
Then (thanks to nicduim!) there is a full factory (rooted) CWM image floating around on the forums here:
http://forum.xda-developers.com/showthread.php?t=1613638&page=6
Which I used to restore my tab to "almost factory" with the missing bloat apps back in place.
I have a copy on my server here: http://ww.mywo.org:88/XDA/sch-i815/ it's the "2012-05-06.22.48.58.ZIP"
unzip that and put the contents on your INTERNAL SD card in the folder clockwordmod. So on your internal SD you should have /clockworkmod/2012-05-06.22.48.58 and inside there the files boot.img, recovery.img etc.
Use CWM recovery to restore this backup. If you never used CWM before. Press power button and volume up and hold both until you see the menu screen with text. You can go up/down with the volume buttons (go slow, it's very laggy) and with the power button you "select" an option. Select the "restore from backup" option and point it to the only folder being offered, the 2012-05-06.22.48.58.
The restore takes a while, then reboot the tab. Now you're back to stock! Last thing you need to do is get rid of CWM again because in the end it's still a bit buggy and will prevent the OTA update from running properly.
Since you luckily have a backup of the factory recovery in form of that factory_recovery.img file, just install and open terminal again, type su and then type (or copy)
dd if=/mnt/sdcard/factory_recovery.img of=/dev/block/mmcblk0p6 bs=4096
This overwrites CWM with your original Samsung Android recovery.
Now you just reboot as usual, connect to the internet and wait until the popup message shows up that a system update is ready, accept it and enjoy
If you don't want to wait for the automatic OTA, you can also stop before killing CWM and use my convoluted 2-step manual update which will get you to the exact same condition as the official OTA.
Hope all this makes sense
I was already on stock FD01 when I tried installing CWM for the P6800 that's floating around here somewhere. Odin said it was a success, but it looks like it didn't take. I've done it a few times, but still ended up w/ the stock recovery. However, after reading through your thread, I do not see a /dev/cdma_update in my I815 either. Is it possible that my attempt to install CWM (although unsuccessful) wiped out this file, among others?
Right now, I'm still at stock FD01 (rooted) and everything seems to be working. When I tried doing an OTA update, it just tells me that I have the latest update and no newer update is available.
One other thing, if I have to, I only have the stock recovery right now since CWM didn't take, can I simply flash both zip's using the Samsung stock recovery to put everything back in stock?

Oh wait, so you are saying that in "About device" your Android is 3.2
Baseband i815.04 V.FD01 I815FD01
and your Build number is already at HTJ85B.I815FD01.SCH-I815.I815FD01 ?
That would mean you are already updated. In this case, it should be pretty easy to fix your problem. Which apps did you delete with Titanium? I can back them up from my system and make them available for you. All you'd need to do is drop the backup files into your Titanium backups folder and then fire up titanium and restore them!
The /dev/cdma_update node is only required WITHIN CWM recovery, so that is nothing for you to worry about. The zip files above won't help you because they are incremental updates requiring your system to be at FA02, not FD01 !
Yes... I'm already in the latest update. I already backed up the bloatware using Titanium Backup before uninstalling. So I just need to restore them back in order to receive and apply OTA updates in the future?

Hi. I'm rooted and removed all sorts of bloatware with Titanium. I did this a long time ago and did not back anything up because I'm used to running hardware with custom ROMs available, and not relying on OTA updates.
Since there aren't any custom ROMs for the i815, I'd like to get ready for the upcoming ICS update. To do so, I want to get FD01 loaded onto my device, but I can't update because I've apparently removed too much of the required bloatware.
Does anyone know WHAT pieces of bloatware I'd need to reinstall in order for the OTA update to apply? I'd assume I can restore them and then apply the update and re-root.
If anyone can help pinpoint what missing APKs might help, I'll give them a shot. And, to the extent I figure anything out, I'll repost here in the hopes that it helps someone else.
electron,
Your instructions worked ... thank you so much
@jkrell... the failed attempt at installing the update should return an error message(s). You just have to read through them until you find the culprit(s). Apparently I uninstalled a few odexed files that were needed. I couldn't update until i hunted them down and restored them.
I guess we all jumped at the opportunity to install the cwm recovery image, that we didn't even think about cmda updates....ooops. So far i had to do a complete factory restore after the update. I was getting soft bricked to the point where I had no choice. Good thing I sent all titanium backups to actual sd card, i was able to salvage 97% f my data..... with the exception of a few downloads i forgot to move.
Gamecih doesn't work anymore (either version). No more automative data hacks I'm not sure what's going on. I uninstalled adfree..used titanium backup to uninstall both versions and reinstalled both several times. Oh well.
It really sucks not having nandroid backups but it's not worth the trouble of having to do this everytime an OTA modem update gets pushed to my tab. Needless to say, I won't be odining the cwm based recovery image again.
I'm with the O.P. I wish i hadn't wasted my money on this tab. No true cwm for this tab, so no dev will ever waste thier time with this tab. The sch i815 will soon be forgotten about and some other tablet will be all the hype before summer ends....that's just how it is. 21 months left on my contract.... [email protected]#k my life. Lol
Thanks Smitty.
When I try to update, I just see the "!" logo and then the device reboots. Is there a log file somewhere I can look at to see what the errors are?
I hear ya on the gloom and doom, but this device has only been out for just over 3 months now. I'd expect a recovery and some custom ROMs to come eventually. I doubt I'll go the custom ROM route unless CyanogenMod is supported, because I have no complaints about the tablet's performance thus far. It's speedy, smooth and the battery lasts forever.
In my book, this is a great tablet and I'm satisfied with the purchase.
Hi All,
I'm in a bit of a unique pickle. I have a Lenovo ThinkPad Tablet 1838-CTO, it is a US 32GB wifi-only tablet with all stock hardware (with disconnected keyboard folio).
I am running build number ThinkPadTablet_A310_02_0037_0075_US
It is not liking to play more than 5 minutes of a video before saying video cannot be played, video it played fine before. Tried all the standard steps, recopying, rebooting, etc etc. The device also sporadically reboots 20-30 minutes into use, sometimes. I have root, rootprotector, and I have CWR. I have not used my tablet since about a week after the first update from my current version above: my device went loopy, THEN the update failed, and I stuck it in a closet, $%^@%$*&@ed off at it for not working.
I want to either (depending on difficulty, and recommendations here) update my device to the latest Lenovo ICS *OR* Run a custom JB ROM (perhaps http://forum.xda-developers.com/showthread.php?t=1778375 though it is for ROW not US, unsure if that matters). Priority on maintaining root access, could care less about what recovery is used, etc.
OTA updates are failing since I had to get CWR , and I am not sure how to use CWR to manually patch/update.
As for the glitching and all that, I am fairly certain it has something to do with when I rooted it, I was a very early adopter of the first permaroot (I place no blame except myself for any and all issues, and muchly appreciate the efforts of others in allowing me to root my device, whether it bricks it or makes it 10x better). I just want to update my device to ICS and start using it again. I have done some searching but am finding that almost everyone is using 0089 or later with the same issue I have, trying to get back to stock bootloader. Honestly I would like to get it on Lenovo ICS, maintain root, and go from there.
I appreciate any and all advice, it's a personal device so I am fairly lenient on what I am willing to try.
Update: I would most appreciate a stock Lenovo ICS dump flashable from CWR if someone knows where to get one, again though any help at all is appreciated.
Update 2: CWM 5.5.0.4 unable to mount the SD card (/sdcard - not even sure if it is trying to mount internal or external, I have ALWAYS had nothing but issues with the external ALWAYS being write-protected no matter the position of the physical slider switch, though it always reads fine - Sandisk 32GB micro-SDHC with Sandisk MicroSD to SD adaptor), so flashing anything from CWM is a no-go. I want to take this thing and send it on a flying ride out the window, the only thing stopping me is it would probably survive just fine to spite and mock me. Sorry about being long winded, rather give you guys as much as possible info.
Is rooting the tablet all you've done? Did you remove any stock apps? I had the same problem with my TPT when I tried upgrading to ICS(from build 0089_US on wifi only 16GB)but only because I had a corrupt busybox file or something. Try going back to complete stock(NO recovery no root) and try to do an automatic OTA 2, then OTA 3. It should work.
How do I go back to stock recovery/bootloader? I rooted back when you had to swap in ClockworkMod Recovery, so my updates fail consistently when I have to reboot to apply, my guess is that the updater tries to pass calls to the lenovo bootloader that do not exist with CWR.
If there is a way to restore my bootloader then I should be all set, otherwise I think I need to find a good cooked rom
Get Some ICS

I posted an ICS Nandroid from a US 32GB TPT, exactly what you are looking for, here:
http://forum.xda-developers.com/showpost.php?p=28240019&postcount=14
It will return you to stock Restore, losing CWM, but you can reinstall a proper CWM for ICS afterwards. See the Development Forum for the updated CWM version that works in ICS/OTA3.
You will have root, but you must download and use OTA Rootkeeper to bring Superuser back (don't forget to download and open SuperUser from Play store).
Good luck!

Going to try it tonight/tomorrow. Updating my Vivid to a non-corrupt CWR then flashing HolICS 1.3 from 0.9b tonight. Oh the adventures I get myself into... XD
Thanks for the upload, I'll let you know if(when) it works, either way I appreciate the effort!

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?
Thanks a lot. Desperately need some help as I'm password locked out!

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!!
