I read a couple of threads before trying my first backup (Solved - 3.1 Update & OTA Full Package) Seemed simple enough. My tab is a July build with Acer_A500_4.010.07_Com_Gen2 purchased in the US. I checked the OTA full package thread and that ROM wasn't available, so I thought I'd back up the stock ROM and see if it was useful to anyone.
I Downloaded and installed:
Iconiaroot 1.3
Root Checker
Acer Recovery
File Manager HD
Did the backup according to the thread.
Rebooted. At that time I decided address the update the system was prompting me was available. I tried to unroot as was advised in some posts and got the message: "Something went wrong you are still rooted.
Tried to root again and the program hung on "Extracting"
Shut down, removed the SD card and restarted.
Checked with root checker and it said I was not rooted.
Tried update several times and it failed about 1/4 through the process each time, so I just reset the tab.
The update still fails.
Do I have a problem or is this just typical of the update service?
Thanks

Did you install the recovery clockwork? If so then install the stock recovery back on the tablet use acer recovery for that.

Thanks a lot. That worked perfectly. I don't know how I failed to pick that up, I read so many threads my head was about to explode.
Any ideas on threads you might have read that explain where the recovery files are stored, how to identify stock, what they actually contain and the recovery process in general?
Thanks again.
I flashed Taboonay 2.1 to my Icona Tab A500 last night. Everything was great. I retrieved all my usual apps and previously purchased apps back down from the market, network was working fine. Turned on tab this morning and it is unable to connect to wifi. Keeps trying several times and then says the attempt has been disabled. It sees the Motorola Surfboard but can't connect. I thought I would try to re-flash since the .zip was still on my external SD. I attempted to boot into CWM but it won't come up. It just says loading image and never goes into CWM, that's it. So, I have no ability to connect by Wifi and am unable to download Acer Recovery Installer in order to re-install CWM. Apparently the CWM image is corrupt. The CWM ROM Manager Premium is still on my desktop but it can't do any sort of recovery because if I bring it up and choose "_install .zip from SDCard" it reboots into recovery mode and can't load the recovery image either. Does anyone have any ideas? Taboonay 2.1 is Android 3.2 it has the xda ad hoc wifi patch in it (which has never been quite right) in my opinion. So I found a copy of the 3.1 wpa_supplicant file and installed it into the /system/bin folder using root explorer to set the permission correctly after renaming the one installed by Taboonay to wpa_supplicant.old and re-enabled Wifi. Still it would not connect. The only difference I could see was that it no longer could see ad hoc wifi networks but still would not connect to my infrastructure wifi although it could see it. This particular wpa_supplicant file that I went back to came from Acer 3.1 stock ROM and worked perfectly under 3.1. I'm basically out of business at this point with no network and no way to flash a new ROM or restore a backup. Does anyone have any idea what to do next. Has anyone else had wifi issues with Taboonay 2.1? I did see an update 2.1b for Taboonay 2.1, but I can't get into CWM to apply it. I might as well be totally bricked. I can connect to the tablet and have full access to the 2 SD cards via Windows and a USB cable, but I can't download Acer's Installation Recovery from the market from a Windows browser. I'm sure its not the router because 3 Windows 7 SP2 Computers can connect to it and so can my wireless HP printer. Everything seems to be a Catch 22. Help! Anyone had trouble with Wifi on Taboonay? Does anyone have any ideas or how to get out of this situation? Any suggestion would be appreciated.
Hey gradyzero sorry to see the trouble buddy but the tabooney 2.1b update is made for wifi updates issues and SU perm, im currently running tabooney 2.1b and full with new market and i have no issues. As far as the recovery have you tried new THORS 1.5 cwm can you try using adb to push recovery.img to the tablet, or maybe using terminal emulator theres a new 1.5 cwm update you can try doing that. just extract recovery img to internal sd and go into thors website "google it" and follow every step except for #3
good luck buddy if not hit me up side PM ill see what i can do atleast to try to get recovery back
I don't think I had restored the terminal program back yet let me check. The apk is something I haven't tried. Thanks for the suggestion. I have thor's 1.5 update on my SD card but not quite sure what use it can be until I can get the ability to connect to boot up in recovery. I'll go to his web site and read the instructions there again, overlooking step 3. I have read them once before but didn't have this problem so I just grabbed the download and planned to update it after the Taboonay flash. Figured it would just have to be redone after the flash anyway. Thank for you idea. I should be able get an .apk onto the SD from Windows and should be able to install it. Again, thanks much buddy. I'll post back to this thread what the outcome is.
Restoration of boot image doesn't resolve the problem.
Okay Crashpsycho I download an Acer Install Recovery apk and CWM Launcher 1.0.0.0 apk. Both appeared to install correctly. Acer Install Recovery came up and I was able to choose to install CWM 1.3.4 image. However, when I reboot into recovery I still stop at "Booting recovery kernel image". So reinstalleing the CWM 1.3.4 image that the Acer Install Recovery show as an option didn't fix anything. Any ideas about why recovery might stop when loading the kernel image? When it says "the Kernel Image" is it talking about the base Linux kernel? I seem to recall reading somewhere that Taboonay replaced the Linux kernel with its own version. Is that true? I thought maybe the recovery image was corrupt but assuming the Acer Install Recovery really did reinstall the recovery CWM 1.3.4 image as it said, then something else is wrong. I did manage to get a terminal program installed so I'll try your second suggestion to force the CWM 1.5 image using adb. If Taboonay really did replace the stock Linux kernel, I have no idea how to recover from that. I'm not quit sure exactly where a recovery image goes and so I suspect that adb will ask for the destination. Maybe I'm wrong but do you know? Does adb know automatically where to install a recovery image? If the Linux kernel has to be replaced then I could get bricked if Tabtoonay won't boot up because a different Linux kernel is installed. What is your thinking about all of this? This is getting heavy. Thanks again for your help. Anyone else that has any fresh ideas is encouraged to jump in here and post to this thread. I'll post back here with the results once I try to force the CWM 1.5 image.
Installing other kernel solved issues for me, using thor kernel 3.5
installing 1.5 use terminal emu, extract the recovery.img from zip folder and place on root of sd go to thors website tegraowners and follow all steps except #3 and that will force 1.5 to tablet. have you tried installing stock recovery image using the acer recovery app
So Sector51 are you telling me you had the same issue. Where booting into recovery locked at loading kernel image? I'll try your suggestion. If it doesn't require you to be able to boot into recovery which I can't. Thanks for the tip.
Crashpsycho, I just completed the terminal method you suggested and followed all the instructions except #3 wihch was a mount, if I remember correctly. I extracted the image file from Thor's 1.5 put it on my external SD by copying it from Windows and then went through Thor's instructions step by step. Recovery boot still hangs at loading kernel image. Thor actually says to install itsmagic into /data/local directory both in his adb push and in his terminal emu methodology. There is no copy of itsmagic in his distribution and I can't find such a file on my tablet. BTW, I also tried the adb push from Windows but the recovery image is pushed to the SDCard so I assume he intents for me to then boot into recovery and to install it. So that's not going to work unless I have itsmagic. The Windows adb method also pushes itsmagic out to the /data/local folder but I can't complete that part and I think it is critical to both methods. Any idea where I get this file? Google search returns nothing except that one entry has been removed due to copyright issues. I think that it is the key to installing from the SDcard. I remember seeing that file on my rooted 3.1 but apparently Taboonay removed it. Can you enlighten me on itsmagic? What is it? Where do I get it? I have currently installed the Stock USA 1.31.06_COM_GEN1 recovery in Acer Recovery but reboot into recovery still hangs at loading kernel image.
This is another side issue but do you know if it would be possible to install the Taboonay 2.1b manually. Is it an update zip or a ROM flash? I'm beginning to think that if I could get back my Wifi back I would just forget the recovery reboot as a last resort. I'm going to investigate what is involved in the kernel update suggested by Sector51. But basically I'm not doing anything else until I can fully complete thor's 1.5 update. Man, I've spent 3 entire days trying to resolve this. I'm going bonkers. It certainly gives me a bad taste for Taboonay that probably isn't deserved because I don't see other post about this particular issue. So please educated me on itsmagic and we'll go from there. Thanks dude for all you help.
I found a copy of itsmagic here on xda. Downloaded it and completly went through the terminal emu process exactly as posted on Thoor's Website for 1.5. Everything seemed to work this time including the execution of itsmagic which spit out a nasty message to Acer something about Its Magic. Acer why did you say the bootloader is locked when it isn't? So this tells me that everything should now be good. I rebooted into recovery and this time it acted a bit different. It still said loading boot kernel but then in about 30 seconds rebooted back to Taboonay automatically. So I'm stumped. Does anyone have and new ideas? BTW, the 1.5 recovery image has a date of 29 Feb 2008. Is that right?
Finally suceeded with 1.5 Recovery, Thanks
This message is specifically addressed to Crashpsycho and Sector51. After four attempts I was finally successful at getting Thor's 1.5 recovery booted. I immediately backed up the current version of Taboonay 2.1 and then applied the 2.1b update. Everything in term of recovery is now good. One problem, the update did not fix the the WiFi problem as I am still unable to connect via WiFi. But that's a totally different issue, which I can deal with. Meantime thank to both of you for generously taking you time to help me resolve this recovery boot problem. I would still like to know what I did wrong during the original ROM flash to Taboonay 2.1 to destroy itsmagic. As well as what I did wrong in my first 4 attempts at repairing the recovery. However, I won't dwell on that as I need to proceed on with working on the WiFi issue. Thanks a million to both of you for all your help and suggestions. You are both what makes xda a truly wonderful and unique place for lovers of mobile devices. I am a programer and web developer and I hope I can contribute eventually to the growing Android mania. I personally think it will eventually dominate the table and phone market, if it already hasn't done so retail wise. I'll return to lurker stats for a while and learn more about the SDK while I try to resolve the WiFi issue. One side note, I recently flashed my HTC HD2 phone from Window mobile 6.5 to Widows mobile 7.5. That involved the flashing of 3 ROMs and then upgrading the OS. It runs beautifully and was much more complicated than what should have been a relatively simple task of upgrading to Taboonay 2.1. I'm sure I missed some small detail that caused the problem with the Icona Tab. You guys helped me greatly and I hope to be able to return the favor at some point. So I consider this issue closed and the moderator should feel free to consider it resolve. xda is power to the people.
Final Note: The adb push from Windows was the last attempt and was apparently the one that successfully fixed everything. As a certified Unix Engineer and somewhat of a Linux expert I opted to use the terminal emulator technique since I knew the commands and what they were doing, but typing in a long stream of commands is always more prone to user error. My advice to anyone else with this problem is to install the Windows Android SDK and use adb push to update as it appears the most recent version takes care of most all the permission issues and is almost fool proof. Again thanks to you guys. The Problem is resolved. Mister Moderator consider this thread closed and resolved.
great job man atleast you got the recovery to work. i cant say much for the wifi issue or what happen to recovery i would say if anything the issue must have came from the wifi ad hoc patch/change but im not fully technically skilled to say that it really was but great job hope you get it back up and going
I am enbrased to admit this but I feel it only fair since so many people attempted to help me. I've search around and apparenty no one has run into this here yet, but it needs to be posted for future reference. Most all of my boot recovery issues took place while the tablet was docked in the Acer A500 docking station. When I have trouble in recovery mode, with the image loading message just hanging up, 100% of the time removing the tablet from the docking station resoves the problem. Just thought I should pass this on. I know it is stupid that I didn't realize this before now. If you are docked, don't boot into recovery' not even with1.5 installed. I have no idea why this is true, but it is. If you have the Acer docking station DO NOT BOOT IN TO RECOVERY WHILE DOCKED!
Open up Rom Manager and click "Fix Permissions" let it do its thing then restart. That worked for me.
[K1] "Unsupported menu option selected" error & where to get TimmyDean rooted 13-13?
I just got a brand new K1. Fresh out of the box with 3-3 pre-installed, I downloaded and used TimmyDean's permanent root tool, flashing a rooted 2-2 firmware. I then enabled the backdoor and ran all the OTA updates up to 14-14. This took several hours in all. I then ran the BusyBox and SU Tools install script. Everything was looking okay. I selected the choice to exit the script with reboot. The K1 turned off and came back on with the Lenovo logo, but, at the top of the screen was red writing:
Unsupported menu option selected: 1
Unrecoverable bootloader error (0x00000002).
It stops there and goes no further. No bootup.
Attempting to research the error, it seems this is not an error too many people encounter or know about, so my guess is that my only way of fixing this problem is to flash the whole thing over again from the beginning. (Unless someone here knows something about this problem. That would be tremendously helpful.)
Having already experienced what it took to go from 2-2 to 14-14 the first time with the permanent root package, I'd certainly like to shortcut it however possible. In this thread, http://forum.xda-developers.com/showthread.php?t=1404351 , TimmyDean posted a rooted 13-13 that we can start from. However, the link to the download file for it is Multiupload.com, and Multiupload.com does not seem to be up for me. Does anyone know where else I can go to try and download a copy?
I'd have posted directly in that Development thread, but, since I am an XDA noob, the forum system only allows me to post in this General section.
After experimenting with the "permanent root" package several times now, each time ending up with the "Unsupported menu option selected: 1" error after any OTA update, I have to believe there is an incompatibility between the K1 I have and the bootloader files in the "permanent root" package. I do not know if my K1 is recently manufactured and they are now doing something different with them that causes this incompatibility or what, but I felt I should warn you all that flashing the "permanent root" package could cause your K1 to not take official updates or to otherwise brick it with the "unsupported menu option" error. Perhaps the 13-13 package, which I don't have and can't test, didn't have this problem.
My serial number is CB1245XXXX. Manufacture date is "11/11/27."
I have now given up on getting root on my K1 and would just be happy to get it back to a working condition that can take Lenovo's OTA updates without bricking. I am currently trying these instructions and will update as to whether or not that resolves the problem: rootzwiki.com/topic/13877-guide-ideapad-k1-restore-to-mostly-stock-with-ota-updates/ (The forum software will not allow me to post hot links, so copy and paste that to browser.)
The rootzwiki procedure did not work to correct the problem. After any update, the tablet is bricked with the error. There are a few threads on the Lenovo support forum on this issue now, and there is no solution.
forums.lenovo.com/t5/IdeaPad-Slate-Tablets/K1-not-booting-after-update/td-p/548285
forums.lenovo.com/t5/IdeaPad-Slate-Tablets/Unrecoverable-Boot-Loader-Error/td-p/683633
I believe these old bootloader files will not work and will brick newer K1's, so my warning is:
DO NOT ATTEMPT TO ROOT YOUR K1'S. DO NOT CHANGE THE EXISTING BOOTLOADER IN ANY WAY WITH NVFLASH. SOMETHING HAS CHANGED.
This might only apply to more recently manufactured K1's, but, since we do not know when this problem begins, it is not possible to know beforehand whether or not you will brick yours.
To be on the safe side, DO NOT ATTEMPT TO ROOT YOUR K1'S. DO NOT CHANGE THE EXISTING BOOTLOADER IN ANY WAY WITH NVFLASH. SOMETHING HAS CHANGED.
Unfortunately, there was no backup option in the rooting packages, so I could not get a copy of the stock bootloader or any other files, if they are indeed of a different and newer variety. If someone has a recently manufactured K1, perhaps you can get those files and share them, because a lot of people are starting to see this problem now.
I have one with sn#1250xxxx, mfg dt 11/11/29. I wasn't even trying to root the thing. I happened during an OTA update. I tried probably all the recovery/rooting option out there. None of them worked. I have the tablet booting at lenovo screen. But I think you are right about the bootloader. If we can get the correct bootloader, we might be able to the the tablet back to life.
fix?
Has anyone come out with the fix for your issue.. I have the same issue . Used TImmy Dean's method.. and anything updating past the 02_02 (loaded from the tool I get the error... Anyone here have access to contact JimmyDean to ask him for help?
I see that he updated the tool to K1_A301_13_13_111209_US and maybe K1_A301_14_14_111209_US but all the links are dead.. anyone have a good place to download the files?
Try out the downloads on the following Lenovo's link -
download.lenovo.com/slates/k1/OTA
those are just OTs.. not image files.. If you don't have a compatable boot loader, you can't load those files.. We don't have a compatable bootloader.. so this is why we need ver 13 of timmy dean..

Can someone who's getting this bootloader error send me a pm. I put together a stock 120109 update that may work around the issue and I need someone to test.
Was this issue ever resolved, I didnt attempt to root mine, only attempted to wipe it clean and got this..
No, no real resolution. What I ended up doing was NVFlashing one of khanning's ROMs, like this one: http://forum.xda-developers.com/showthread.php?t=1560441
I don't know what's going to happen when I have to update again, such as the upcoming Ice Cream Sandwich update promised by Lenovo.
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?

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.
I have an Acer 500a I just bought off carigslist. Initially I thought it would be fine but then I realized I was inheriting someone elses problems. I hope someone may be able to help.
Within the first few hours I was noticing google Play crashed a number of times and struggled to update from Market. Somehow the update went through but now there is a system update that won't go through. I'm able to down load it and when i restart the computer to complete installation the screen goes black and says: booting recovery kernel in the corner. I then see a picture of an android and a load bar which after 2-4 seconds the android is on his back and an exclaimation mark is coming out of his belly.
My android version is 3.2
Kernel version
2.6.36.3+
Build number
Acer_a500_7.006.01_COM_GEN2
I'm pretty sure its rooted and i think that might be why its not playing nice with google market and system updates. I called the old owner and explained the problem and he just said he had it rooted and he thought he unrooted it. There is an ap called superuser in aps. (although if it were rooted would'nt I be able to uninstal some of thecrap software it comes with like GOLF HD? -- it won't let me).
The system update is for Acer_a500_7.014.01_COM_GEN2 8.88mb
My problem is all of the force closes I'm getting and the inability to update the system. Any thoughts? I don't have a usb cord to connect it to a desktop either =(
I am a bit out of practice, but...
Should be pretty simple to fix. From what I am seeing, you are running a stock rom. Just because the superuser.apk is installed on the system does not mean it is rooted, but it probably is.
Hit the market, grab "Root Checker" - simple tiny program to let you know for sure if your tab is rooted or not.
https://play.google.com/store/apps/details?id=burrows.apps.rootchecker&hl=en
From what I understand - automatic system updates will fail when trying to apply them to a rooted or modded system. Probably why you cannot auto-update.
My advice at this point would be to:
1) Since you just bought it, just do a factory wipe on it. That will remove all the stuff the prior owner had running on it and will result in a unrooted tab that should be able to get auto updates without a problem.
2) Un-Root it. Once the tablet is unrooted, the system should update without any issue.
As for your Play Store issues - I have never heard of or personally seen any issues caused with installing apps from the store on a rooted device. I have seen a few apps that will refuse to run on a rooted device - but that does not sound like your problem.
I would go with option 1 - just factory wipe the thing. Prior owner may have made tons of changes to the OS that we will never know about, and may have handed you a unstable system. Start fresh. Wipe it out.
Hope this helps you out! Let me know if I can answer any questions.
k thank you so much for the quick reply! I downloaded the root checker and it Is rooted. I did a factory wipe as found in the settings privacy tab when I bought it. That factory reset did not unroot and only cleaned out some of the aps on the device. Is there a better or more surefire way to unroot it? If I reset with the volume down key will it hard reset it?
Thank you for you help!
Draight
Okay.
I am about a year out of practice with my a500 - but from what I am think, if a factory reset still results in a rooted device - the prior user installed a stock ROM that comes pre-rooted.
I highly doubt being rooted is causing the issues you are running into.
At this point if you just want to get back to stock you can probably just install the Acer Recovery Manager from the market and use it to reflash a stock unrooted ROM. Or I see a few guides about how to manually restore back to stock over in the dev section for the a500.
Others will correct me if I am wrong, but I think Acer Recovery Manager should take care of your problem.
Hope this helps!
(Edit: Or you can just download the official stock 4.x rom (ICS) from the dev section and flash that. 3.2 is pretty slow and wonky in my experience, you should be able to just download a 4.x ROM and flash, since you are rooted. Again, I am way out of practice. Don't do anything before reading up!)
(Edit again: I think I was making this harder then needs be. Just flash any stock 3.2 unrooted ROM, done. After you do that the automatic on the air update should kick in for you and update you to ICS)
Thanks for taking the time to work with me on this. I downloaded the program you suggested and tried to use a stock rom. When i went to reboot I had a picture of an android looking up at an exclaimation mark. It was froze like that until I restarted it. Now its back to the way it was, rooted and unupdatable.
I'm probably going to try to just wipe it all over but do i need to plug it into my computer somehow? I dont have a usb connector for the tablet, just the wall charger plugin. can i just download a rom and use the utility to try install it? when I reboot it am I supposed to be pressing the volume button?
I've read a few other forums but usually they sound pretty intense...

Hmmm..
Try the thread I linked two in my second edit of my last post. You just need to grab the stock and unrooted 3.2 - put it on a MicroSD card as update.zip - then reboot with vol rocker and power switch to get the system to flash the update.
That *should* work just fine.
(Edit: Forgot the link! http://forum.xda-developers.com/showthread.php?t=1839313 - there you go)
Thankw, I am going to try it after readingna bit more. Do I need to have clockworkmod installed for all of this?

Nope. Just snag the stock unrooted 3.2 ROM - place it in the root of the MicroSD card as update.zip
Power down.
Power up with VOL + and POWER key held at the same time (you can let the vol rocker go when you see text appear in the upper left corner)
Should be all you need to do. Worst case; it does not work and returns you back to where you are now. Worth a shot.
If that does not work, let me know so I can do a few mins of homework and help you further. Been a long time since I have changed ROMS or had any issues with my a500.
I have bricked it twice by not following directions all the way or just making simple mistakes, but from what I have found there is always a way to recover.
Just tried it. I copied the boot zip to sd card and renamed update.zip and reset..It looked like it was going to download after showing some text in the corner and then an exclamation mark appeared above the androids head... I left it and after a few.min it rebooted back

Like I said, I am rather out of practice.
Someone more experienced them me: please help me point Draight in the right direction here?
Thanks for trying to help. =(
I wish that my tablet wasn't having such issues. I;m going to try to scramble around the forums and see if I can find some advice...If anyone has a suggestion please let me know.
Thanks again entropy,

Update:
So I've been tinkering around with it a bit more and I found a usb cord that plugs it into my computer. I keep finding boken links on this site so Im struggling to find an update I can use to flash to. I downloaded a different super user program which allowed me to temporarily unroot my device. I then restarted it and no root checker says its no rooted and I cannot find the superuser program. I think I have somewhat unrooted it -- but I think the real issue now is the recovery tool. I keep reseting it - hard reset, or factory reset and it wipes everything away but when i try to update it gets about 1/3 of the way up the bar then it stops with an '!' Mark above the droid. Im kind of annoyed at this point and hoping for some new links or some ideas on how to repair the recovery piece.

Go to the Dev section, and grad a couple of the ICS Update roms. You will see them listed for the a500. Make sure they are the FULL update roms. Should be about 3-400mb. These contain a FULL ICS Update Rom, and not a patch file.
http://forum.xda-developers.com/showthread.php?t=1816560
Then, go to the Themes and apps forum. You'll see a sticky that has the Acer Update Decrypter.
http://forum.xda-developers.com/showthread.php?t=1869505
Now, unpack the decrypter, and select one of the ICS Updates. Then hit Start. Take a couple minutes, but you will have a duplicate file with the word "decrypted" added to it.
Wait, you are not done yet.
Using a program like 7zip, or even Winzip, open the decrypted file. DO NOT EXTRACT, just open it and pull the update.zip to your PC's desktop.
Copy that update.zip file to your Ext SD Card of the tablet. Don't be putting it in any folder, just copy it to the root of the card.
Now, you still ain't done.
With the tablet off. Press and hold Vol+ and then PWR. Hold them both untill you start to see text about installing blah blah blah, then release the buttons.
If it completes, and you can reboot into ICS, then you are good to go.
If something fails during installation, then decrypt the other update Rom file you downloaded, and do the same procedure. Usually one of the 2 or three should work for you.
Note these are for the a500, and not the a501.
One more thing. It's advisable you get your UID number before doing these things. You probably won't need it, but it's nice to have written down in case you need it in the future. Inf to get it is at;

Thanks! I am downloading a few of the FULL ICS roms:
*Acer_A500_1.031.00_WW_GEN1 : http://d-h.st/uAy

The I downloaded the ones ending with Gen1. Once they are downloaded I will continue with the instructions. Thank you so much for your help! I will post how it goes later tonight.

I just decrypted both:
*Acer_AV041_1.054.00_WW_GEN1:
*Acer_A500_1.031.00_WW_GEN1
Both get get to the third bullet quickly and the bottom says DONE! It takes like 4 seconds. I don't think the Decryption key of $12 is working
[*] Opening file: Acer_A500_1.031.00_WW_GEN1.zip
[*] Decrypting using key $12
[*] Writing decrypted file: Acer_A500_1.031.00_WW_GEN1_decrypted.zip
I try to extract something from the decrypted file and it says the file was not downloaded properly and I should try redownload it...it says its not a proper archive
wahoo!
So that worked! I down loaded the file Acer_AV041_A500_1.033.00_PA_CUS1 and extracted the update. I palced the update on the sd card and booted with the power and sound volume pressed down. it went through the installation procedure and restarted twice before saying it was upgrading my aps and BOOM its got ICS and everything looks great. Thank you so much for your help and I hope that this paper trail is able to help someone in the future
My problem is that I'm on ICS and I'm rooted, but I just can't download a custom recovery. I've tried, and I haven't gotten anywhere
