I have been working on this for the past few days and for the life of me cannot figure out the problem. I'll start by just laying out a sequence of events.
Bought A500 about a month ago. OTA'd to HC 3.1 4.010.13_com_gen2
Decided not to wait for OTA 3.2 and rooted with iconiabreak.
Did not do a backup (like an idiot, i know)
Flashed Taboonay 2.0 with Thor's 2.1 kernal.
Saw awesome post to get rid of cell standby by deleting phone.apk and telephony.apk....do i did that.
Realize i am an idiot and then run a Nandroid backup.
Was happy for a few weeks when i see that Vache had updated taboonay to 2.1b and decided i wanted to do that.
Downloaded the files and started to flash with CWM. Factory, cache, dalvik wipe. Run Taboonay zip.
Get stuck in bootloop at Taboonay boot screen. $#!t......
Think "it's ok, ill just do an update.zip and go back to 3.1"
Try almost all the files on Vache's full package and update thread.
I put each one on an ext sd card and throw it into recovery boot. The Android guy with gears shows up and it looks like it is going to work.
The progress bar gets about 90-95% of the way when everything just stops. Gears animation, progress, everything.
It then reboots and gets stuck in a bootloop at the android screen. Load a different update.zip and same thing happens each time.
I try to just do a normal recovery boot, but CWM isnt there anymore and i get the ! android.
Normal reboot gives me a bootloop.
So i am stuck and asking if it is the phone and telephony apks that caused everything? if that were the case, how would i be able to load them back up since im totally locked out. I havent tried adb since im out of town for a few days. Thanks for any help that anyone can lend me. Ill try to answer any questions for any information that might be needed.
bumping for great justice~
I've tried decrypting update.zip files and vice versa.
still no luck..
try the fall back to 3.0.1
Check under development section for iconia a500. You'll see a thread for going from 3.2 to 3.0.1.
As i readd about this rom, it seems it's used in difficult cases (it removes the locks created by 3.2 stock), so it could be worth giving it a try.

Thanks for the reply.
I don't think that will be a viable option for me since i'm not able to get my UID. i've plugged my tablet into the computer and gotten the "hardware found" bubble. It prompts me to look for drivers (which i havent be able to find) and, i assume because it's in a bootloop, wont show up on the computer.
Does anyone know why the update.zip files would fail at 90%? I think that's really the thing that boggles my mind and is most frustrating.
Did you at all have your A500 connected to your computer prior to this happening? If so then you can get the UID from by way of the Windows registry. Then you should contact SC2K and get him your UID he should be able to help you get your A500 back from the dead.

Unfortunately, no I never plugged my A500 into my computer.
quick update:
I was able to use a different computer and found something interesting.
While trying to transfer or open a decrypted update.zip file, i get an error message saying, "Please insert the last disk of the Multi-Volume set and click OK to continue". Clicking OK just brings it back and i am forced to click cancel.
Anyone have any idea what that would mean??? It doesnt happen when I open or transfer the non-decrypted file. Only the decrypted file using Thor's Acer Update Decrypter application on HC 3.1 and 3.2 files.
While loading the decrypted update.zip on the A500, it almost instantly shows the ! android guy, while the non-decrypted files go 90-95% and then reboot into bootloop.
Any help would be greatly appreciated!
first off if you can get into recovery to flash anything.You are not bricked.
Take your SD card put in a android phone format it.
Put the card in your computer.copy a full update.zip file from dev section.likes on a post by Thor.put card.back in tab and flash.
If it stall fails repeat with a different SD card.seems smaller ones do best.
Good luck.

Thanks for your reply, first off.
I'm sorry I didn't make it clear that I had done all of those things during the events of the first post EXCEPT try a different sd card.
So I went out today and bought a PNY 2GB sd card as opposed to the SanDisk 4GB i was using. I formatted it in my Atrix 4G and threw a full update.zip file in there. The first file I tried (from Vache's http://forum.xda-developers.com/showthread.php?t=1113878 thread) was Acer_A500_4.010.38_COM_GEN1 (HC 3.1). Since I was able to open the .zip without decrypting it I loaded it only the sd card. It did the same thing as before (loaded to about 90% then freeze, reboot) except this time I got a "Boot verification failed..." message in bright red letters up at the top left of the Acer screen. Since it didn't work, I loaded Acer_A500_7.006.03_COM_GEN2 (HC 3.2) onto the sd card. Again, since I was able to open the .zip file, I assumed that there was no need to decrypt it. Loaded the sd card and put the tablet into default recovery (not CWM recovery which I no longer have). The same problem keeps happening: it loads to 90%, freezes then reboots. This time, however, it went into a bootloop at the "android" screen.
I've tried decrypted versions of those files, but I always get an error message while trying to open them and when trying to flash them in default recovery, it almost instantly goes to the ! android guy since I'm assuming those files are already decrypted and decrypting them again is bad.
Hopefully if I try enough files, I'll find the one that works...
Until then, if anyone has any ideas as to what I might be doing wrong or should be doing differently, please let me know!
Thanks.
there is a thread that has instructions on going from the OTA 3.2 to downgrade. To 3.1.look for that tthread and windows software. On that thread it talks about that error your getting.
Since I have not had this issue .can't say for sure if it will help.
Good luck sorry I can not do more to hhelp
Just a dingy blonde here.

Thanks for your suggestion.
I was able to find my UID from an old CWM backup file and tried this method. I attempted it last night with no success. I was actually in the middle of making a reply saying how heartbroken I was and that I was basically giving up. I decided to try it one more time and made a slight adjustment from my method last night. In the UID file, I had my UID in there as 0x0blahblahblah and kept getting the incorrect UID error in the program. When I tried taking out the first 0x in the program, it gave me an incorrect format error. That is where I was messing up.
Instead of 0x0, all i needed was 0blahblahblah in the UID file.
Attempted the upgrade utility again, and viola! It worked like a champ.
So thanks again to all that helped out and offered suggestions and to all the Devs for their outstanding work. I've definitely learned a lot from this experience.
OK, I've come into a roadblock and have searched the forums and google... But to no avail.
I bought a refurbed Nook, and it came with V1.2 firmware.
I ended up downgrading to 1.0.1 (by accident, I had meant to downgrade to 1.1) and then ran the auto nooter (for 1.1). Some reason, it worked. I then installed CM7. It seems to have installed a seperate Bootloader or Recover (im not sure maybe both). Problem is, I dont have root (or at least, I dont have SU permissions. not matter wether I run CM7 (WHEN it actually boots) from the NC itself, OR when in Honeycomb via booting it from the SD card.
I have searched and searched how to get the NC back to stock to try to start over, but I cant seem to do anything right on this machine.
When I boot into CWM (From SD Card) to try and format system/data, it locks up and seems to not have been successful... When I try to reinstall CM7, it boots with the big android (like a rooted stock FW). When I try to install CWM from a honeycomb run from the SD card, it kicks back with no superuser permission to run the install (Rom Manager loads correctly, but doesnt get SU perms).
When I try to boot into CM7 then reboot into recover, it locks up on "Booting into recovery"
can SOMEONE help out?
Found V1.2 firmware:
http://www.mediafire.com/?a1lg5w8thbbkp9t#1
(Wanted to do a strikethrough on previous note, but unsure how...
Figured it out...
Had an old version of CWM (I was on 3.0.0.5, needed 3.2.0.1)...
Rebuilt NC by formatting Data/System folders, then incrementally updating from 1.0.1 to 1.1 to 1.2 to 1.3.. Had to piece together a bunch of different tutorials and forum posts.
Looks like the problem I encountered was starting with a newer version of CWM to try to root, then switching to an older version which was causing me to be unable to properly format my /DATA folder which kept carrying bad info from one install to the next... SO FAR, SO GOOD...
HOPEFULLY, my mistakes will help someone in the future.. I'm going to go back and look for links to all the stuff (or maybe I'll just post dropbox links and host the items myself)
Hi,
I try to downgrade my current A500 on HC 3.2 to 3.01 with any success.
I follow to tutorial based on "Vache" tips available at http://forum.xda-developers.com/showthread.php?t=1276227
I have done all the step, but when i launch PBJ20upgrade.exe as administrator, it ask me to plug again my iconia, it display the current installed version and version who will be replace, click on "Next" button and... progress bar doesn't move.. the iconia switch off (black screen). I have try many times and always the same result.
My current configuration is :
Kernel : 2.6.36.3+ - build : Acer_A500_7.006.01_COM_GEN1
My computer is on Windows 7 64bits.
Any ideas ?
Have a nice XDA Christmas.
Method 1 can take up to 10 minutes or longer to get action. Perhaps you didn't wait long enough.
Try Method 2. It's even easier.
Not sure if it matters, but set your USB Debugging to on. Settings/Applications/development
USB Debugging is set to on.
When you said "Method 1 can take up to 10 minutes or longer to get action." it's mean before seing the progress bar moving ?
In any case i will check method 2 but just a little bit afraid with the " gives errors and crashes but you only need it to root and install CWM"
One small question, with STEP 2, it will replace the current HC 3.2.1 by an unstable 3.01.
Let imagine after the procedure (root + CWM) i would like to put a ROM STOCK as my iconia was delivered, i think it's possible no (and where to find it because i have no img of my current version because not rooted).
And if i do it (install rom stock) it will be updated to HC 3.2.1 with OTA no ? Root and CWM will be lost again in this case ?
Thx for reply.

No Problem. Remember, sometime, systems will reboot. And sometimes, you have to wait. I cannot tell you that this is happening with your case. But, it is best to wait some time.
Both methods, I believe, will give you an unstable version of 3.0
Yes, both methods, will replace the current operating system. But, between errors, it will allow you to run the iconia root, and run the acer recovery. I don't think anybody has failed to do this, except for idiots who can't follow instructions.
I would suggest you download these, and put them to SD before starting the procedure. It saves having to get them from the net. Also, go ahead and download a rom you want to try. Might as well do all things at the same time.
True, basically, you will be without a stable recovery. Which is why, after you install Acer recovery, and install the recovery part, it is necessary to make a backup of the current system. Better an unstable one, than no system at all
Then, do your boot to recovery, system off, hold vol- and pwr till you see the text in the top left corner, then release.
Nav is by the vol - and +. Pwr to select an option.
Wipe;
1. User data
2. Cache Partition
3. Go to Advanced, wipe delvak cache
Go back to previous screen, and select Install From Zip, choose zip to install, and select your rom
Wait 10 minutes or so.
Now, when the rom boots, and it will, if you get several error mesages, then, you should reboot to recovery, only this time, goto mounts, and format the partitions. Usually, you don't have to do this. But, sometimes, traces of the opld rom remain behind. But, I think you will be ok with the previous procedures.
And, you're a good boy, as you ask questions before you do things

Hi again,
Sorry but i have a stupid question. Based on solution 2 for downgrading (by using a SD card) if it's so simple why we don't use it to flash any ROM like Thor or Tabonnay ? just by placing the "update.zip" file on the SD card and boot on recovery stock ROM.
I understand that "rooting" a tablets allow to have full access on it (all partition) but why it's necessary to replace recovery tools by CWM ?
Sorry for this stupid questions but i love to understand what i'am doing.
Hi again, so i have done the downgrade with step 2 but have some issue.
V 3.0.1 is installed and iconia root 1.3 too
concerning "itsmagic" where to get it (when i should put adb push itsmagic /data/local)
Second, for the second part of tutorial http://forum.xda-developers.com/showthread.php?t=1126364, i need to type some bash command on the tablets, but how to ?

Easier to download Acer Recovery from the http Market, and install it on your tab. Then flash the Thor Recovery.

To make a long story short, it won't work.
Basically, the OTA updates have a special script to run, also, they update the bootloader of the tab, which of course is more or less off limits to use poor people Not to mention the updates are "officially signed" by acer, to allow this method. And I am just guessing on this, but probably pretty close.
Anybody else have anything to add?
I suppose, a lot of time could be invested in creating a custom rom using this method, but it seems more simple to use the "recovery" method.
So it's mean that i don't need CWM and itsmagic but just "Acer recovery" ? i can cancel this part on STEP 2 ? :
5. then install CWM from thor's site (there you can find the latest version) or use Acer Recovery Installer from the Market, or look at the original thread here
6. Boot into CWM and flash whatever ROM you like!
The main problem with the market, i can connect but each time i use the tab keyboard i get an error message as describe on the unstable HC 3.01, is there a way to have an APK version (i can upload it on my microSD card).
Thx a lot.

Yeah, that keyboard is a killer and causes a lot of issues. I heard where if you mess around with the keyboard settings (a lot), it will actually settle down and work with few errors (but looks bad)
Yes, skip the adb stuff
Use your computer to access the android market web site. Search for acer recovery
Download, put it on your sd for your tab, and install it using any file manager app. Then start the app, and install the Thor Recovery. You can get Thors recent recovery later, so it's not necessary right now.
Acer recovery is a tool that makes it easy for people who do not know how to use adb.
If you can't get it done that way, then you'll have to use adb.
The directories specified in the commands, are the locations they will push the files to. The img to the sd, and the it's magic to /data/local
Never used it myself, so I am not so sure where you are supposed to place the files to begin with. I would guess in the same directory as adb.
Thx for help, when you said "Then start the app, and install the Thor Recovery", Thor Recovery is included on the A.R.I apk file if i understand well but not the last version.
2) I donwload a ROM like TABOONAY or THOR on my microSD card
3) Just after, i reboot on recovery mode by using A.R.I
4) From CWM i select the image located on my microSD card to flash my tablet
right ?

Ok, AFTER, you run the acer recovery, install, start app, and install the recovery. Should be the only choice you have
After it does it's thing. Then power off. Then, hold Vol - then PWR button, until you see text in the upper left corner of the tab, then release both buttons.
It will boot to the recovery menu.
Now, it's ok to copy the rom you want to use to the sd before doing all this. No problem.
With Taboonay, I would look at the procedure, as I believe you have to have 2.1 installed first, before upgrading to 2.2. (not sure why he decided to do it that way. Seems like a pain in the neck. I used to run 2.0 for awhile.
Harkon, is also a nice smooth rom.
Thor's V14 is also good (a500 only)
Then, very important. When you boot to recovery, go ahead and make a recovery image of your current rom (yeah, so it's unstable). Always most important to do this, as sometimes, a flash can go bad. Not often, but, better to have a recovery image to go back to, even if it's unstable.
Next, do your 3 wipes. No, not the toilet
1. User data
2. Cach partition
3. Go to Advanced, then dalvek cache.
After it's done, then, you can go back to the main menu, and select Install zip from SD
Then select your rom.
It takes awhile, so have a beer
And ... MAKE SURE you have at least 60% charge on your tablet!!! Before doing things.
People forget, and,,,, it ain't pretty...when your tab shuts down in the middle of a flash.
Nice, totaly clear for me right now. Many thx to you
And to finish, 3 last question (next beer will be paid by me of course )
1) If right now, at my current step (only donwgrade done to 3.0.1 at this moment) i do a factory reset on me main menu of my tablet, what version i will have ? Current unstable version or my previous HC 3.2.1 ?
2) When you said "Ok, AFTER, you run the acer recovery, install, start app, and install the recovery." by install the recovery you mean CWM provide on the A.R.I, there is a special menu on ARI to install it or it will be installed automatically during ARI APK installation ?
3) When you speak about "and select Install zip from SD" the ROM should be on the internal memory of the tablet or on the external (microSD card) ?
One thing that i don't understand yet is the internal structure of the partition on the tablet. As i understand, for the moment i just made a downgrade from HC 3.2.1 to 3.0.1, but we have the possibility to do a factory reset, so i think when we do that, the iconia will restore an img file or iso file from a specific partition.
So if i understand, on my current state, if i do a factory reset as usually, the HC 3.2.1 will be replaced no ?
In any case, thx a lot for time spend by you to explain me all this... this is the Russian POWER

1. Do not do a factory reset. Honestly, I do not know what will happen at this point.
2. The Acer recovery, comes with Thor's recovery program. I think, that is the only one that comes with it. Technically, you can use it to flash roms, but, I advise using the recovery built into the tab afterwards. Usually, this program will go away after flashing a rom.
3. Always in the "root" of the SD (the first file you see when you look at your sd with a file manager).
4. If you're in Moscow, I will take that free beer
Not sure exactly what will happen when you do a "factory reset" I would suspect, the same OS your device came with, but I really don't know. Never had to do it. And, I see a lot of issues when other people try it.
so, today i have installed Rom Stock, Thor and Taboonay... all those has been tested and at the end Taboonay has win (Thor is pretty good but the fact that tab is detected as ASUS is not so good for me).
Many many many thanks to you Moscow Desire for you help concerning this, all is ok for me right now and more clear.
last question, if i want to update current version of CWM (provided by ARI) how to do it ?
I have download "update-recovery-thor2002ro-rev1.3.4.zip" i think i should use CWM itself (on recovery mode) to update it ? right ?
Have a nice christmas !!!!!
Good work. Glad things worked out for you!
I've been lazy, and haven't upgraded my recovery, but I believe you just place the Thorupdate.zip on the SD like you did with Taboonay, and boot to recovery, and flash just like your rom. But really, I haven't done this yet. Maybe this weekend.
Shouldn't be any need to do wipes.
Also, if you want to run a different Kernel on Taboonay, Then you need only to wipe Delvik cache before flashing it.
Merry X-Mas to you as well, but here, we celebrate New Years.
I know it for christman, i work sometime in Russia (near Moscow). Normally for you it's hollydays since yesterday, very lucky people in Russia.
Happy new year to all XDA members !!!!
FYI - if you do a Factory Reset with the unstable 3.01 rom installed, it puts the CURRENT OS back on, this being unstable 3.01. You have COMPLETELY replaced the other OS. This will happen whether you are running a custom OS, or official OS.
You can only have one OS on your tab at a time, unless you do the dual boot but that opens up a whhole new can of worms...
I need help! I need a stock, unmodified recovery partition image.
Anyone here with a vzw tab who DOES NOT yet have CWM installed?.
PLEASE contact me.
Thanks!

I have one that hasn't been moded but have no idea how to get you what you want. PM me if you know how to download and send to you and I'll do my best to help.
I'll check my laptop at home tonight. I believe I kept my heimdall backup before flashing cwm

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?

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 everyone.
Just repeating again - the model I have is A501 on stock 3.2.1 Honeycomb - a more USEFUL tablet with 3G and WIFI capabilities...One would think it would be a much more popular model, but the A501 doesn't have its own board on XDA; its merged with this board for the less practical A500. Basically, I have created this thread as I don't want to take any 'extra' risks in successfully installing ROOT with the CORRECT ROM with the most updated version of Android available for this tab, for example Jellybean...
Another A501 user, beny9 posted:

Following TimmyDean's method (thank you) I have now managed to install 3.2 Honeycomb A500 ROM with success after completing steps 1-15 inclusive from his README file. As you will know, I don't have 3G or GPS functionality, so I need a stock A501 ROM to install.

Your best bet is to install a good 501 HC 3.2 and get on HC for your 501.
The files are available. What you'll probably want is a full HC Update rom for the 501. Note that some of these Acer roms are encrypted, so you'll need to decrypt it first. You can find the decrypting tool in the Themes and Apps forum, as a "Sticky". After decrypting, you can pull the update.zip out of it, and copy to Ext SD (do not extract, just pull the update file out). Boot the tab holding Vol- and PWR I believe. Might be Vol+ but I can't remember. This should force the tab to look for update.zip on your SD and install it.
I would use this one;
Acer_A501_1.309.02_4.031.24_COM_GEN1
After it installs, and you get it set up, you need to get Acer Update Enhancer from the Play Store. This will allow your tab to get the ICS OTA.
Keep in mind, there is only 1 official ICS OTA update for the 501, so don't expect more. It may do it in 2 steps though.
If you want root on ICS, there is really only 1 way to get true root and adb system remounts. And that's to flash the V8 unlocked ICS Bootloader, and flash an insecure boot.image. There's currently a small package that'll give you somewhat root, but it's a pain and really doesn't do a good job. So it's better to get the V8 and unsecure boot image. Might be a good idea to also install CWM Recovery at the same time.
Get the correct rom installed first, then check back if you need help.
Oh yeah, one more thing. When you are on HC 3.2, get your UID number and write it down somewhere. You need this as a safety precaution. There's a good sticky thread on how to do it. Pretty simple really.

Ugh. I have a pain in the A$$ version of AVG...even under advanced settings there was no disable options. Managed to figure it out to run the Acer Decrypter EXE and fix the image you have advised I should download and flash. Will give that a go now...
Thanks again!
Just to fill you in, this issue is solved.
1. Used TimmyDeans rollback V4 tool to a 500 rom
2. SD card was not recognized in CWM or Stock recovery. Was however recognized in the HC OS.
3. Formatted SD Card using Mini Tool formatting app. Format primary partition only to fat32 (defaults)
4. Decrypted and pulled update.zip from this 501 HC full update rom
Acer_A501_1.309.02_4.031.24_COM_GEN1
http://forum.xda-developers.com/showthread.php?t=1816560
5. Did OTA update to 3.2.1
6. No more OTA available, even after installing Acer Update Enhancment tool.
7. Downloaded and used Blackthund3rs Bootloader management app
http://forum.xda-developers.com/showthread.php?t=1622425
8.Downloaded V8 and CWM package, unzipped to the same folder as the tool
9. Ran the 500NVFlashapx app.
10. After completion, booted to CWM recovery, wiped and formatted, and install Moscow Desire's RaptorX almost stock ICS rom.

Hi MD,
I have Acer Iconia A501 tablet. My tablet suddenly showed andriod logo with exclamation mark when it was being used. Upon looking at your posts, I found the resolution which I tried. I am not expert in this all, but I tried running your ROM "41-124-01-A500-update" from one of your posts which was actually meant for A500. This resolved the issue successfully and tablet was up and running.
Then further I found full ROM for A501 as mentioned below and thought that I should try the ROM meant for the model of my tablet.
I successfully decrypted the ROM that you mentioned "Acer_A501_1.309.02_4.031.24_COM_GEN1"
When I tried to update it with the mentioned ROM update.zip, it did updated it from SD card and passed android symbol with those gears running. However, when it restarted the tablet by itself, it showed ACER logo and then it showed "ANDROID" (spelling in blue color) which kept on flikering slowly for long long time....for more than 30 minutes and did not moved further. Can you please let me know whats could be wrong?
I also tried ICS ROM, but that didn't worked (it failed). So after couple of trail and error, I moved back to A500 ROM update.zip which I knew that is installing successfully.
Can you please let me know what shall be done in case I want update.zip for A501? It will be highly appreciated if you can upload update.zip directly that I can use and that gets installed successfully.

Muk

Hey Muk, I can probably guess the ROM you installed doesn't do data wipes and such, so it caused an animation loop.
Try this one. It's an SD ROM, so it "should" wipe your Data, along with installing the ROM.
https://mega.co.nz/#!NZBlBSLQ!mOHICp7gbinkYeHCvrEz7aKXsWQjjquAWq_XC_lSQzk
As you probably discovered, Acer has pretty much removed almost all tablet ROMs. I snagged a few the other day, then checked yesterday, and they removed all from their support site.
I would guess they are getting out of the tablet business.
Also, they shut down their OTA Update servers for a few months now.

Hi MD,
Thanks for your super fast response. I am downloading the ROM for A501 from the link provided by me. I will update you if it works in my tab.
I forgot to mention you about one message that I received once tablet is restarted. So, once ROM for A501 from SD card has performed its job successfully....that is that android symbol with gears in its tummy is successfully finished and tablet restarts. It shows "Acer" (spelling logo) and then after it gets stuck at "android" (spelling logo). Between these two, it displays two lines messages on top left corner for 2-3 seconds that the "blob is illegal - abort" and then gets stuck at "android" (spelling logo). I think this might be useful for you to identify something.
Another thing about wiping out the data, in starting when we press volume down and power button, it does display message about SD card (still not not sure about whether it might be wiping out the data or not....I believe you might be correct that it might not be wiping out the data).
Another thing, that I found in my backup is that when I purchased this tab (A501), I downloaded HoneyComb 3.2 Kernel Source Code from the Acer support site. Is this something that you can do magic with and provide me with update.zip? Please let me know....if you can do magic with this, then let me know how shall I share it with you.

Trouble installing ROM for A501
Hi MD,
Thanks for your super fast response.
I tried downloading the ROM for A501 from the link provided by you. It downloaded it from the cloud, but at the very end it displayed message "Decryption Error". Still I tried extracting "update.zip" from the zip file, but it displayed message that the archive is corrupt and file is corrupt. Can you please check at your end and provide me with fresh link or directly with update.zip? For your reference I have attached screenshots of errors.
I forgot to mention you about one message that I received once tablet is restarted. So, once ROM for A501 from SD card has performed its job successfully....that is that android symbol with gears in its tummy is successfully finished and tablet restarts. It shows "Acer" (spelling logo) and then after it gets stuck at "android" (spelling logo). Between these two, it displays two lines messages on top left corner for 2-3 seconds that the "blob is illegal - abort" and then gets stuck at "android" (spelling logo). I think this might be useful for you to identify something.

Trouble installing ROM for A501
Hi MD,
Please read my earlier message and then read this one.
Thanks a lot....your answer about my first problem resolved everything.... (your answer was "that the ROM that I am trying to install is not clearing the data"...I verified that the ROM is clearing the cache, but not the user data. I can confidently say that you correctly identified the issue as when the ROM installation was stuck at "android"....I switched off my tablet and tried installing again the old ROM for A500 which I knew that it is working and instead of asking me to configure the tablet (i.e. time zone, date & time setup, etc.) after installation, it simply logged in and started my tablet as usual....that means that when I was trying to install ROM for A501, it was not clearing user data and was then hanging).
Now coming back to the link that you sent me in previous message, I was able to download the zip file successfully in the second attempt. I extracted the update.zip and it did not work. It showed the similar problem of getting stuck at "android". However, with your great answer that you gave me, I cleared the user data and cache manually by pressing vol up + power buttons simultaneously and then when "acer" symbol displays, releasing only power button and turning on and off the lock button. This cleared user data and cache. After that, since update.zip (that you provided) was already in my SD card, it installed the ROM and tablet works perfectly. Thanks a lot....:good:
One question, when it asked me about the zone, it had only few countries like US, UK, etc. I couldn't find Australia...is it because this ROM not for Australia? I understand that this is not an issue, but if you find anything for Australia, do send me.
Another thing, is this HoneyComb 3.2? Will 3G and GPS work in this one?
Do let me know if you can do some magic with HoneyComb 3.2 kernel source code that I have as mentioned earlier.

Muk

I'm mobile right now, so can't go into big detail.
In your settings, about tablet, you can always find info on which specific OS you have. If you indeed have an A501 and the settings tells you that your tablet is a 501, then your 3g and GPS should function.
The only 2 differences between an A500 and an A501 is of course 3g. Also, they use different GPS radios. So you can install 500 Roms on a 501 and vice versa. Just the above 2 items won't work. Also, I believe I gave you a 3.2.x ROM. Getting it to ICS 4.0.4 may be a problem.
I revived my own 501 last night by putting the motherboard in the oven, but now it doesn't read my ext SD card, so I may be stuck on 3.2. Eh, no problem.

Hi MD,
Apologies for very long replies. Wanted to convey the message in detail how I did it so that it might help someone else like me.
Thanks for your response. I have tested it, 3G and GPS is working fine. I believe, before my tab encountered this problem, it was having version 4 which should be ICS. At that stage I didn't had any problem with my tab...I believe it was there for long time.
If you have good known ROM for ICS, please forward me I can try on my tab. If it doesn't work, then will re-install the Honeycomb that you sent earlier.
One more question....when I try to update the system from "About Tablet" in Settings, why it displays message the the "network is poor" and advices to move to better coverage? Though, I am just besides my WiFi modem and coverage is almost 100%.
And @jonnybrave: If you are referring to the ROM that I successfully installed which was sent by MD earlier, then it does not need any decryption. So you can use the link sent by MD earlier in this post. And if you are referring to the KernelSourceCode that I mentioned earleir, then it needs some kind of processing in Linux machine and then you can create some image.....this is was I know about it....sorry not an andrion guru. Please let me know what you are referring to.

Mukesh

You get the message as do all 500/501 owners (it can change depending on version of Rom).
Acer no longer gives updates to any of their devices (regardless of age). These are otherwise known as OTA Updates. So they have closed their update servers, so now we get some "message" that absolutely means nothing.
I suppose Acer is getting out of the Android business and no longer supports anything. Nice job Acer.
As for updating to ICS (or any other version), I have a few update files. Generally though, the update files must be matched to the current version of your tablet. Sometimes you can run a "full update" and it will work.
The problem, is these tablets are getting old, and the nand memory can go bad. Running an update can cause a variety of problems such as "Stuck in APX" mode, stuck at bootloader, stuck at boot animation. Then we have to go back to the EUUS file, or an old SD ROM file. So you run the risk of doing things all over again, and the risk that it just won't work again. (I spent a couple hours last night, and was almost ready to throw it in the garbage)
For example, I'm pretty much stuck at 3.0.x or 3.2.x. I've already disassembled the tablet and put the mainboard in the oven, just to get it back to life! And after numerous attempts to get ICS on it, I've pretty much given up before it hard bricks again. In fact, I can't get a 3.2.x EUUS to work on it, so it is stuck at the 3.0.x ATT EUUS. Eh, it's my little girls tab, so as long as it gets You Tube and browser, it's pretty much ok.
Trouble installing A501 ROM
Hi MD,
I am in the same boat as you...lol...This tablet is mostly used by my daughter and as long as it is solving my daughter's purpose, we are happy
I was just curious about that message as to why that is happenning, but after your clarification, it is clear to me as to why it is happenning.
My tablet is working as normal and everything is working fine...so we are happy with what we have.
Thanks a lot!

Muk
