[Q] Downgrading 3.1 to 3.0.1 - Acer Iconia A500

i wanted to know if i can downgrade from 3.1 stock to 3.0.1 using acer recovery tool. I want to downgrade because some of the apps that i would like to use keep force crashing on 3.1. i have tried reinstalling the apps and nothing works.

If you made a nandroid backup using clockworkmod (you should have), just do a full restore. ba-da-bing.
The acer recovery tool you mention is just for installing clockworkmod, it won't install a rom itself. clockwork mod does that.

i didn't create a backup so i guess i'm out of luck.

Maybe you are not... Dexter provided a stock rom on his first post here:
http://forum.xda-developers.com/showthread.php?t=1121790

Check this post. flashing those 4 files (don't forget itsmagic), will put you at version 1.104.02_GEN1_COM (U.S. Stock).
Skip flashing the recovery if you don't want to lose ClockworkMod.
http://forum.xda-developers.com/showpost.php?p=14967064&postcount=206
If you want a specific version, ask someone to uplaod a ClockworkMod backup of boot, system and flexrom and use ClockworkMod to restore it.

thanks euclid. I might try this later but i can't figure out itsmagic. I installed the clockworkmod recovery with acer recovery installer. Can i just boot into recovery after that and have itsmagic work?
edit: i got its magic running then did the steps in the post minus the recovery. when it was done the device rebooted and got stuck on the acer logo. after that i booted into clockwork and installed the 3.1 update.zip and now my tablet is working fine again.

I *CANNOT* boot into ClockWork recovery!

I am on a rooted Samsung Vibrant running Froyo and CWM 2.5.1.2. I cannot boot into CWM's recovery. I tried flashing CWM again and again, but I didn't work. I tried reinstalling packages at least 5 times and nothing. I just boot into the normal recovery. It worked the very first time I tried it, right after I rooted it and I installed CWM for the first time, then I had to reinstall packages twice. I used super-one-click to root my phone. I am using the latest version of busybox. I have given ROM Manager superuser access. I reinstalled ROM Managed. I deleted the clockworkmod folder and update.zip and installed CWM again. I have tried re-rooting twice with no success. What's the problem? It worked the very first time I rooted. But why not now?
I have this happen from time to time with ROM Manager....I just go clear down to the bottom and install an older version...say 2.5.1.1, hit reboot into recovery and it does, and then I update back to 2.5.1.2 and it will work after that on the newer version

Sorry, that didn't work.
Opps didnt see the Froyo..you need a modded 3e recovery here http://forum.xda-developers.com/showthread.php?t=833423
Yea you have to use the "froyo" version, but you will also need to delete slacker radio from your phone via titanium first. That is the only way it would work for me.

Sorry, that didn't work either. Should I just restore to the stock 2.2 on my Vibrant? If so, where would I get the Stock 2.2 Vibrant files?
How do you feel abt voodoo?? You can install one of Supercurios kernels with voodoo and it will give you CWM recovery and root

Damn...Im still half asleep.....I re-read your post...the update.zip has to stay on your internal sd... I saw you deleted it which is why CWM isn't working. ROM Manager adds to that file when installing CWM Recovery.

It is in my internal SD. It's at /update.zip It added that every time I downloaded CWM. Should I Odin back to the stock 2.2?
You can.. that way you start out fresh and eliminate the chances for errors

Sorry, I'm a noob to the Android scene, How would I restore to Stock 2.2 for Vibrant? Is there a guide or tutorial?

When you ran the script to get the recovery to 2e, did you put the phone into shell root first using super one click?

I am having the EXACT SAME PROBLEM AS THIS GUY. And it's really frustrating, I have been working at getting this ****ing phone updated to some version of 2.2 for about 5 hours now.
Just had to say that.
you on 2.1?
UPDATE:
I flashed 2.1.1.0 clockwork... whichever one was at the bottom of the list. AND I uninstalled Slacker Radio (dont know if that helped it for sure)
But After reinstalling the packages, then booting to recovery with the volume buttons down, I reinstalled package AGAIN and then CLOCKWORK INSTALLED OR WHATEVER! So now I'm flashing a new rom from it! thanks!

I ve had to downgrade ROM manager before also...so you might be ok to move back to 2.5.1.1 after your flash
Also, earlier today I did this: http://forum.xda-developers.com/showthread.php?t=804305
So that may be part of his issue.
Clockwork seems to be hanging on installing my ROM right now...
is it normal for the progress bar to not move once it hits "Formatting DATA:..." ?
yea as long as it keeps saying Formatting, Copying, deleting...it will move if it flashes good..

When you did this where you on 2.2 (kA6) or 2.1 (JI6)?
im asking because im on 2.2 but for the life of me i havent been able to get clockwork to run. ive done almost every single step there is out there and have had no luck, but im thinking that my phone is HW locked so that may be my problem.
i can flash any stock rom through odin (JFD) (JI6)
and (KA6) through kies mini
but i cant get into clockwork recovery in any of those rom's.

[Q] Stock ROM->Cyanogen Via Androot and RomManager?

Is it possible to go from Stock ROM to CyanogenMod via this path:
1. Using Universial Androot to root
2. Install RomManager from the market
3. Install Clockworkmod recovery 3.0.6 from Rom Manager
4. Install CyanogenMod from RomManager
That would be very easy compared to using adb. And it does not require a PC like the various one click root methods.
It should work?
I am asking because these optiions are already in the cyanogenmod wiki (some of them put there by me)
And if it works without problems, it should probably be the recommended update path.
I might try it out myself, but it requires me to go back to stock rom, which I haven't done before. If I understand correctly, it is not possible to flash a 1.6 ROM from a new Clockworkmod recovery, I would have to go back to maverick or amon ra recevery?
I am running Cyanogenmod nb 12, and clockworkmod recovery 3.0.6 at the moment.
to get back to stock rom, you just have to connect your phone to the PC, and double click the .exe of the ROM
I am not using windows, and do not have a rom exe file. I rooted and flashed my phone via adb on linux. I do have a nandroid backup of my stock room after it was rooted though.
Then flash back the old amonra recovery, before restoring your backup because it won t work with the latest clockworkmod

Ok thanks, I just heard from some one at cyanogen that using RomManager to flash the recorvery on a rooted stock rom won't work. So I guess the update path in the first post is not valid...

Uhm... I think not: is missing the "insmod tattoo-hack.ko" and it will fail the "remount" operation (and then the flash).
IMHO.

Yes, I think you are right. Stock rom needs the tattohack loaded before flashing a recovery.

Well, i had a CyanogenMod "installed" on my tatto, and i flashed it back to the stock 1.6 rom without installing anything, without problem.
i guess that's the question, isn't it?
I used the method you're saying, Androot+Flash Recovery from Rom Manager to the latest ClockworkMod and unfortunately it's not working.
I don't know if it is because the new clockworkmod but my advice is don't use this method. I posted some questions in other threads but nobody could help me.
I reflashed Clockwork several times even to 3.0.6, but the startup recovery menu still the same.

brick Nexus S

Hello. i am new to the android family
i have a nexus s GT-9020T
i have rooted my phone but without setting the clockworkmod reovery.
today i was playing with the rom manager and downloaded one of the rom from the list. after installation i was unable to start the phone only seeing the google logo with the unlock logo.
i went back into the recovery by typing flash recovery recovery.img etc.
run a restore and restart the phone but still not work
my nexus s is 2.3.4 by the way.
please assist
What "restore" did you run?
Go here: http://forum.xda-developers.com/showthread.php?t=1056062
And download the full rom:
Model: i9020T
Full Rom: GRJ22, KD1
That'll revert your Nexus S to the latest completely stock 2.3.4
Then you can flash recovery again and go back to clockwork mod and go flash another rom or whatever.
Remember when you're flashing a new rom you need to wipe data and cache and dalvik cache.
i run an restore from the backup that i made before installing the new rom using clockwork mod recovery, its part of the option when installing the rom using the rom manager * click box - backup * etc something like that

Next time don't use Rom Manager to make backups or flash roms. It's stupid and can get you issues like you're having.
Anyways, try wiping data and cache then restoring the backup, do it in Clockwork Recovery.
Let it boot, first boot always takes a while, 5-10 minutes. If you see the boot animation freeze, stop and restart, then yeah it's screwed up, otherwise, just let it is.
If still not working from your backup, do what I said in previous reply, just restore to stock 2.3.4 then re flash clockwork mod and start over with the rom you want to flash.
thank your nxt. i have found the real problem. it was not my backup problem or the rom that u provided. it was the version of my clockwork mod recovery. i was using an 2.x.x.x to restore the phone which is why it doesn't work. everything work fine now after i flashed with an 3.x.x.x and restore the phone. one question thou, where can i always find the newest clockwork mod recovery release ? thank you very much

Or just use ROM Manager to get the latest.
That's the only thing I use ROM Manager for... getting the latest Recovery.
thanks again nxt. if you don't mind really ...i have one more question. i know the phone intend to uninstall clockwork mod recovery once its restarted. i know there is command type into the cmd to avoid the phone uninstall the clockworkmod reovery and make it permanent in another word. I didn't run those command when i root my phone because i don't know if its good to make it permanent like.... hmmm like if there will be a 2.3.5 coming next month..just saying ok... with a permanent unofficial recovery will cause a problem?

Are you running custom ROM? If you are, it's already made to not revert back to stock recovery. If you leave it stock recovery you'll get notifications for firmware updates by Google, but remember that applying those to a rooted phone might screw things up too.
the blue one is stock recovery right?

Don't remember. It should only have like 3-4 options.
thanks again nxt. no i am not running an custom rom. i mean not yet. i planed to try one from the rom manager download section then my phone couldn't start after installation and now i have restored my phone from my backup using the clockwork mod recovery 3.x.x.x.

prep for OTA

hi guys. I was running us update 1.147.07 before installing cwr and then switched to 3.1 leaked. When I ran my restore it took me back to 1.147.04? I then used Acer recovery tool to install stock recovery 1.147.07 . But system build still sits at 1.147.04. Tried a factory reset and still at 1.147.04? Will I get the OTA too 3.1? I'm worried I need to somehow reinstall the 1.147.07 that was pushed to the tablet but can't pull from settings. Any help?
Any suggestions? I can restore to 3.1 leak rooted cwr or my stock 1.147.04
Sounds like a mismatched flexrom to me. Did you backup the flexrom partition?
Sent from my A500 using Tapatalk
You seems trying to use Acer recovery tool to return to 1.147.07 but it should be impossible! Acer recovery tool can help you to restore the stock RECOVERY but not your system so you can't go back to 1.147.07. You will need to find a 1.147.07 package(>300MB) and flash it. Hope this help you!
Let me know what you need to check my flexrom version. i wanna get this straightnend out

I used acer recovery to flash CWR. i then used CWR to flash 3.1 leak. I used CWR to then recover the stock backup I had. and then used acer recover to reflash stock recovery
Those interested in getting back their OTA, properly backing up their original ROMS or restoring them, please follow the tutorials in this thread:
Going back to stock TUTORIAL
Be helpful and provide your firmware if you have a backup so we can build a database for those who don't.
Be sure to report what is working and what is not working for you once you've tried the tutorials!
Unlike the 14 threads on these matter I take the responsibility as OP to upgrade my original post as firmwares and new info becomes available.

CWM recovery not working on HC 3.2.1

After the OTA 3.2.1 update, CWM Recovery would just not install. After flashing the CWM recovery image on stock 3.2.1 and rebooting into recovery, I get the android guy with the exclamation mark. I saw another person in the CWM thread having the same issue.
I did flash CWM before on HC 3.2 successfully, but for some reason it is not working after the last OTA update.
Any thoughts ?
Any luck on this? I'm trying to root my Xoom 3.2.1 and have no idea what to do and looks like the one click tool has been removed...any direction is better than no direction ;-)
Thanks!!

I had this same issue yesterday.
Use adb and fastboot to manually install clockwork again...and then if you need to root you can use one click root.
I would give you the code for fastboot command but I'm not home.

well, it seems that you need to immediately boot up into CWM recovery after flashing it without letting your device boot up completely, then you need to root it from there to retain the CWM recovery. This worked for me.

Can you expand on this a little bit? I am on stock rom, rooted and unlocked, and running 2.6.36Tiamat_Xoom kernel and build HTJ85B.
IF i do the new update what do I need to do to keep root? Will I have to wipe everything?

Yes. What I did is backup everything, flash back to stock, wait for my device to download and install the 3.2.1 update, and finally flash the recovery, root my device, and install the tachi kernel. Restored all my applications after making sure that everything is fine.
I know it looks like a long a process but google market applications restore saved me a lot of time.

To save even more time and get back your app data, first back up aps and data in Titanium Backup and make sure the backup is on your external sdcard, just to be safe. Then, after wiping, and once you have rebooted, reinstall TB and then run a batch restore of missing apps and data. It is much faster and better than letting google restore the apps.

Yesterday just rooted my xoom but now i have a problem when i try to flash something or do something in recovery doesnt work it say cant open sd or cant mount sd any help

Even simpler... fastboot flash just boot, system, and recovery stock images. Leave userdata alone. Allow the update. Don't worry about letting it fully boot.. let it.. no harm.. but no root.
Then flash CWM (using fastboot).. boot to recovery.. CWM univ root. Good to go. Or CWM a different kernel
