Can you reverse flashing a recovery image?

Hi Guys,
I'm a little new to all this so please bear with me..
Just rooted my MT4g and want to make a nandroid backup before i do anything. However i see that i need to use CWM to flash a custom recovery image in order to make the backup.
Is there anyway to reverse that recovery image back to stock? Incase i need to revert the phone completely back to stock...
Thanks.

Sorry, i think i found it!
I'm guessing this is it: http://forum.xda-developers.com/showthread.php?t=843289
Please close this thread if that's it.. sorry for spamming.

If you completed the root process then you already have CwM recovery. Just use Rom Manager to make a backup. If you have to revert back to stock the process will reinstall the stock recovery img for you.

Hmm okay. I did successfully root the device and I was following this write up to backup the phone using nandroid which says i need to flash a custom recovery ROM.
I just tried to backup current ROM and it gives me a message saying i must flash CwM recovery first and gives me an option to install it. But i'm guessing it's possible to restore that from the link in my second post?

You can use clockwork to restore your factory rom, but if you want to revert your recovery back to stock you will need to fastboot flash the stock recovery back on. This is assuming you have first flashed the stock rom which will leave you without clockwork rom manager installed. There's a few unroot guides that will help you if you need to send your phone back to tmo. I would suggest becoming familiar with ADB and Fastboot. That knowledge will give you more options in a pinch.
Swyped on my rooted MyTouch4G

Thanks much!
Yes i am doing a lot of reading right now, but wanted to make sure all the files i needed were out there for the MT4G already. Looks like the factory recovery is out there and it can be flashed back so i'm not to worried.

Yes all the files are out there that you would need to pretty much do whatever needed. Check out the links in my sig for some good things.

[Q] Acer Recovery Installer

Acer Recovery Installer from the app store says it is a brainless install of CWM for our device. Has anyone had any luck using it to install Primee or any other ROM?

Dunno if right forum but works great, I myself installed newest Clockworkmod from sdcard using this. I suggest you download newest version from here. And name it as recovery.img on you sdcard then install that one using Acer Recovery Installer
EDIT: Have tested PRIMEE and PICASSO both working great. Ask if you need more help.

Thanks for the feedback! i am blown away that now with 2 apps, you can have a rooted custom rom on the a500. go devs!
(I was unsure if it went here or apps, mods feel free to move it or kill it entirely.)

Yes it does work!!! Perfectly!!
I used the Acer Recovery Installer and it was SOOO EASY!!! I was able to flash PRIMEE AND the PICASSO ROM's so they do work.
Just FYI though, if your RECOVERY is not able to MOUNT THE SD CARD then try to use another one because it is very touchy... Not even re-formatting makes it recognize it... I dont know if its a limit to the size but I used an 8gb sandisk and it did not recognize, but my 1gb sandisk ran just fine with it... jejeje
Just my 2 cents... jejeje

I also have used this to install the PICASSA rom. Very easy! No hassle whatsoever

I just want to make sure how to get back to stock if I need to send it to repair center. If I backup the old recovery using the recovery install app, and do a full backup using CWM recovery, can I return to stock simply by restore the full backup and the old recovery? Thanks!

lol what is so brainless about it, i have used adb to install through command and used the recovery installer, only difference i seen was the recovery installer was much faster no need to type commands to flash. and the installer makes it simple to roll back if needed

Even I would like to know the same. I am now on the Prime ROM and have taken the full backup of the existing stock ROM.
Thanks

Absolutely correct. Do full cwm restore, to get back to stock rom. Then use this app to restore your stock recovery that you backed up. On a side note, if /system/install-recovery.sh in your stock rom is still executable (enabled), then stock recovery will be restored automatically.

Sorry for the noob question but there are two 1.3.4 archive files: update-recovery-thor2002ro-rev1.3.4.zip and recovery-thor2002ro-rev1.3.4.rar. I downloaded and opened both and while they both contain recovery.img the zip file has the image in a CWM folder.
Does it matter which one I use and do I need to extract recovery.img or simply rename the entire archive to recovery.img?
Thanks for the help...

I'm pretty sure the image in both are the same (correct me if I'm mistaken). The zip is packaged to be run as an update from within clockworkmod. Whereas the rar file just as the image for you to flash manually (or with Acer Recovery Installer), which now has 1.3.4 built-in.

It looks like images contained in the files are the same (same file size anyway). Moot point now since as you pointed out the new version has 1.3.4 built in - but thanks for taking the time to respond.

Are you backing up to the micro sd or the usb? I was getting an error backing up data to usb. Not sure why it would have a problem, but I was only able to do a backup to micro sd.

Use With "Official 3.1"
The Market installs version 1.5. As I updated to the "Official 3.1" , can I assume that Recovery Installer 1.5 will install CWM on my Iconia and then I can install other ROM's? If so, any special precautions (aside from backup)?

It will install CWM just fine, as long as you tell it to do that. If you don't, it won't.
As for precautions. Yes, absolutely yes, back up your current ROM from within CWM before flashing a new one. There have been WAY too many complete planks begging for help in restoring to stock lately because they either can't read, or think they know best, and didn't bother backing up.

I didn't make a backup because my Acer had German only language and I wanted to flash Official English rom in any case.
But could someone tell me what was the rom version that cam with Acer in the UK?
Was it COM_GEN1 or something else. I doubt that I'll return to stock (ever) but it would be nice to know.

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?

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!!
Faslane

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?
Thanks

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

You need to have an exernal sdcard for the recovery images to work.

Hmm that's weird, have you tried re flashing your recovery maybe something is broken there? have you tried other roms? If using TWRP try to update it or change to CWM or vice versa

Yea I updated to 2.6.3.4 which as of my knowledge is the latest
Sorry for my noobness :/ it is really bugging me as I think it has something to do with having cyanogen installed before but then again after pursuing the flash tool and restoring back to stock I can't think what is wrong

Double Flash seemed to fix it
I flashed the ROM after returning to stock again and before flashing it wiped all partitions and it still stuck on boot so i went straight back into recovery and flash again this time without wiping anything as i was only writing over the StockMOD install and it seems to work
So the solution for me seemed to me to flash it twice wiping before the first and after it fails to boot just flash it again without wiping.
I now have it up and running and I'm very happy with it
Thanks for those who tried to help me much appreciated
