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...
If this is some sort of duplicate post, please delete it, but I could not find something like this anywhere. I want to share my method for gaining root access + installing CWM recovery on the Rogers Galaxy Tab 10.1. This should work on other variants, those who can confirm please comment and I'll update the post.
Update:
Now confirmed on WiFi model AND Verizon Model (thanks Rockaholic94 and badogg for testing).
Rooting:
1. Download this file and rename it as "update.zip"
2. Put the update.zip file on the root of your tab's SD card
3. While your tab is powered on or off (doesn't matter), hold the volume down (volume up on VZW Model) + power key to bring up the option to select recovery mode or download mode.
4. Choose the recovery mode option (box picture) by hitting the volume down key then selecting with the volume up key.
5. Now that you're in the factory android recovery menu, choose "Install update from SD card".
6. Highlight the update.zip file using the volume buttons and the power button to select.
7. Confirm Superuser is in your list of apps
Let it do its thing and it is now rooted.
Installing Clockworkmod:
1. After confirming the Superuser app is installed and you in fact have root access, download ROM Manager from the Play Store.
2. Open ROM Manager and choose "Install Clockworkmod Recovery"
3. Select "Samsung Galaxy Tab 10.1" to make sure the right recovery is installed, and wait a minute or so as it installs.
4. Towards the end, ROM Manager will prompt you for root access to complete the install.
Congrats, you now have root access and CWM Recovery.
This was tested on my 3G device running 3.2 for the record, but it should work on 3.1 also. Please let me know what devices you've been successful using this method for, and remember the "thanks" button too .
Guide was written by myself, but I grabbed the root file from this post on Android Authority. Props to whoever the original owner of that file is... Also, not responsible for bricking devices etc etc etc.
For which versions of the 10.1 will this method work?
It works 100% on the Rogers GSM 3G model, so it should work on any 3G variant. The tabs are branded as "4G" here in Canada but this method has not been tested on an actual 4G (Verizon) device, or the Wifi only model.
I did it on my Wifi only 10.1 tab and it worked perfectly.
Awesome! Great to hear.
Great! I don't like using Odin (once had a semi-brick when flashing with Odin, probably due to a bad cable connection), so I like this Odin-free approach
I'm not a huge ODIN fan myself. I only have experience with ODIN from my 7" Galaxy Tab but I like simple methods that don't require a computer. I completed this method by simply using Dropbox to transfer the root file to my device, the built-in file manager to rename the file, stock recovery to flash it, then CWM via ROM Manager from the Play Store......... NO WIRES
unroot?
Many thanks for this!!
I also don't like ODIN, not to mention that I only have Mac thus booting into Windows everytime I want to use it.
This "no wire" method really is better and way easier, do you thing unroot method can also be made that way?
Bye, Dejan.
I'll look into the un-root method and update the post accordingly.
worked on my 4g rogers model.
Thx!
The zip only adds superuser app & su binary, so I would suspect that simply removing these 2 files would be enough to unroot.

Few newbie questions regarding flashing.
If I flash this AOKP am I able to uprage it to ICS when it is released?
Or am I forced to flash back to stock rom?
You'll need to either revert back to stock to get the official OTA or just wait on a flashable custom version you can flash via ClockworkMod.
I'm personally just going to flash a new version of AOKP once it is updated with the camera drivers (since none of the ICS ROMS currently have working cameras). The cameras aren't something I use on my tablet so I'm currently living without them.

I tend to use the camera, so I'm waiting for that to finally get updated. I'm hopeful it comes soon, with the alleged 'soon' release.
I did get CM9 nightly up and it looks good, but I'm going back to Honeycomb stock. (having difficulty going back, but that's for another thread)
The only reason I really don't like the stock ROM is the lag, not to mention they're pretty slow to update this particular device. ASUS seems to be on top of keeping their devices updated, but they don't offer any 3G/4G tablets here in Canada.
After seeing ICS reviewed on the new 10.1 tab, it's sad to still see lag on a revised version of the device. I'm not overly confident that the ICS update being pushed here in June will be much better than 3.2, for me it's going to provide camera drivers and that's all it will be good for.
So..if I root using this method, how do I unroot in case I need to?
Thanks for help
As of right now you will need to use ODIN to unroot and revert to stock unless someone finds a flashable .zip method or something (which will only unroot, won't restore stock recovery). I've been busy lately so I haven't really looked into any unroot methods yet. As far as I know there is this method for restoring a WiFi only Tab to stock, which does wipe your device keep in mind:
http://forum.xda-developers.com/showthread.php?t=1474971
The only reason you'd really need to unroot would be for warranty reasons I suppose, but it would be nice to have a quick and easy method.
galaxy 10.1 tab model gt-p7500 how to root? root.zip does not work
Hi :
I have a galaxy tab 10.1 GT-P7500 model and trying to root it.
tested root.zip and does not work
any other alternative method?
I would like to confirm that this method works on the VZW tab. Only trick is that you must press volume up instead of volume down to enter recovery.
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!

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

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;

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

I have experience rooting a Xoom, an Atrix, and an S3, but at the same time I usually just follow instructions to the bullet point while only vaguely understanding what I'm doing.
I got my cracked screen replaced at a non-samsung outlet yesterday which I'm pretty sure voids my warranty, and if so, I want to take advantage of that by rooting. But a lot has changed since the last time I rooted a phone - they're talking about "systemless root" and flashing an SELinux Permissive Kernel and then "Oh no wait you don't have to flash such a kernel in this new version" and I have no idea what any of that is referring to, all that stuff is new to me.
I have a Canadian Note 4 SM-N910W8 running the latest COK3 OTA update on 5.1.1. I found this rooted ROM which I'm pretty sure is the one I want, but then, it's the only one I found, if there are more or better rooted ROMs please let me know:
http://forum.xda-developers.com/note-4/snapdragon-dev/trltecan-n910w8-aoa1-stock-rooted-t3025538
The instructions for how to install it keep changing for every version though. It also says I need to start by flashing TWRP via ODIN - Okay, I've done that before, but I want to make sure I get the right one. I found a couple of sources:
http://forum.xda-developers.com/note-4/general/ref-stock-firmware-kernel-modem-recovery-t2920452 - twrp-2.8.7.0-trltecan.img.tar
and:
http://galaxynote4root.com/cwmtwrp-recovery/ - openrecovery-twrp-2.8.1.0-trltecan.img.tar
Not sure which one I should use.
All I want is to be able to edit the keyconfig files to get my USB controller working, to be able to edit system files to change the Touchwiz aggressive background app closing and allow apps to remain in memory for much longer to make it more like Windows memory management, and to be able to install Xposed modules like statusbar volume.
But I want to make sure that I'm doing everything *exactly* right, and that's why I like to ask real human beings to confirm my plan before starting. So I download one of those TWRP files, download ODIN, plug my phone into my PC, use ODIN to flash TWRP, boot into TWRP, use TWRP to wipe data, cache, dalvik, and system, and then install the rooted ROM I linked above. Have I got all that right? What's all this SELinux and systemless root stuff I keep hearing about, and why don't I need to do that anymore with the latest version of this rooted rom? Will this break any key features on my Note 4 like my spen or my external USB or my blood oxygen meter or all the cool novelty **** that Samsung Note 4 comes with?
Right here goes the rom u have is the right one for ur phone. There will be others around byt u can try that ome to start with. The twrp recovery u need is the 6th one on the list down the model numner is at the end of the file name, its the .tar file u want zip can be used also but thats using recovery to flash the rom. Using odin 3.09 latest one i think. U need to hold down volume down, home and the power to boot into download mode open idon with kies closed and end task with task manager in window.
Now whem oden starts u need to select the phone tab and choose the twrp recovery and flash that leaving everything unchecked apart from restart and reset time all others should be blank, i flashed with erase nand and nearly bricked my phone, thats one to leave for the experts lol.
Once u flashed recovery i think u need to root even though the rom is rooted rom i think it needs to be rooted before u flash the rom, not sure but its what was on the instructions i followed. If u try find a root file off here for ur phone u do same as u did flashing the recovery file and tjats it wait for phone to restart and reboot fully after flashing each recovery and root, i always do from knowimg its best ti imstall wimdows apps ome at a ti, e and reboot between the installs as less syste, errors can happen that way , well not system errors but linked dll files not been copied right and the like.
Thanks

Still need help them post back and will do my nest nut i a newb, i have an understandimg of how things work but by no means am i an expert i do what u do, i follow imstructions and learn as i go along what thimgs are and what they do, best way then u kmow what ur messing or dealing with.
U also, well i did for my 910f need to use a specific twrp or at least the latest release.
The walk throughs on most sites are all the right way to do it, just others are explained better than others and imclude other stuff if it goes wrong which believe me it can go wrong, easy as not seeimg a check box tocked or not ticked and boom paper weight lol

Okay but what about the other site I found, the XDA forum with TWRP recovery files? They seem like newer versions, but then that left me wondering if the reason the other site has older versions is because it's just outdated, or because only the older versions will work.
Thanks for all your help btw!
Your welcom, the rom you want is fine, u want to go for either of the roms version 3.21 de bloated or regula,, de bloated is where they take slot of apps by google and also carrier apps that sometimes come installed.
