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.

Stuck on MyTouch4G logo screen and can't restore nandroid - please help!

So I followed the guide to root with s=off and it seemed to work fine and I installed clockworkmod v3.0.0.5 through ROM Manager and had made 2 nandroid backups and everything seemed to be working great.
Then I tried to install CM7 RC1 through ROM Manager, thinking if anything went wrong I'd be able to restore the nandroid backups.
Something went wrong and I ended up stuck with the CM7 skateboarder animation infinitely repeating. So after pulling the battery I was able to boot into recovery. It looked like the stock recovery, but after selecting factory reset it went into Clockworkmod. From there I restored my backup, and everything seemed to work fine.
But when I reboot it just gets stuck forever at the MyTouch4G logo (the first one that comes up immediately on power up, not the second, round logo.
I've tried to restore both backups but always get stuck at the same screen.
Right now I need to get the phone working as fast as possible, hopefully to one of my backups (but if I can get it working I've also got MyBackup Pro and Titanium backups of my data and apps).
Can someone tell me what's the best way to get this working again and hopefully if it's possible to successfully restore my nandroid backup?
Thanks!!

Current:
Rom Manger (v3.0.1.0)
Recovery (v3.0.0.5)
When you go in Recovery from bootloader what color is the text green (2.x) or orange (3.x)? Keep in mind if your using 3.0.0.5 which has Recovery 2.5.1.2 then you can't flash CM7 as you need to use 2.5.1.4(Recovery) or 3.0.0.5(Recovery).
If you meet the basic requirement as you still have the rom on your SDCard. I want you to go in Recovery via bootloader. Then go in format and wipe /system, /data. Then go back in advance wipe dalvik and from main screen wipe cache, then do full factory wipe it will remount all. Once this is done select Install zip files> Choose zip files> Find and run the rom> select yes.
When you load for the first time give it some time as it will take few min but if it takes more than 5min than ya its in bootloop. If you get to the part here then it should be working but if you get stuck in mytouch 4g logo then it won't load. Now if you have green(2.x) text then what you need to do is install the Recovery 3.0.0.6.zip though Recovery as you won't be able to access Rom Manager and then try to flash CM7RC1. Let me know if you have any problem or its hard to understand. I know people always get Rom Manager and Recovery version number confused and the whole problem get started.

It says "ClockworkMod Recovery v3.0.0.5" at the top and bottom and has orange text on a black background (highlight line is white text on orange background).
This morning I managed to get it to boot by flashing PD15IMG.zip from HBOOT (took me a while to figure out I have to keep holding both down and power to get to HBOOT, just holding down and releasing power took me to ClockworkMod which wouldn't install the file).
Then I set up my account and downloaded MyBackup Pro which I used to restore visionary+ and rom manager to re-root and re-install clockworkmod then I rebooted into recovery and tried to restore my nandroid backup.
Same problem, stuck in the boot logo. So seems like these nandroid backups are useless.
Is there any way I can recover the backups? At this point I don't have much time to play with CM7 so I'd rather just get my phone back to where it was and play with CM7 a bit later when I have more time. If necessary I'll just go back to PD15IMG and manually restore using MyBackup Pro, but that backup isn't quite as fresh and it's a pain to restore the widgets, etc.
I'll try doing the wipes you suggested and see if that will bring back my backup...
Thanks!

To be clear:
ClockworkMod Recovery 3.0.0.5 -- the orange text version -- CANNOT be used with Stock ROMs, or any other Froyo-based ROM. Not backup, not restore, and not install. It is only for Gingerbread-based ROMs, like CM7.
Froyo and Gingerbread versions of Android use different filesystem structures. CWMR 3.0.0.5 is for EXT4 filesystems, which the Froyo kernel cannot mount.
At boot up, the Froyo kernel tries to mount /system, and fails, because /system is in EXT4 format that it doesn't understand. So the Froyo kernel crashes, reboots .... and fails again. And again.

That explains it. Thanks.

So I installed ClockWorkMod 3.0.0.6 and used that to restore my last nandroid backup (even though it was made in 3.0.0.5) and that seems to have worked!
CM7 does look quite nice. I look forward to playing with it when I have more time.
Thanks for your help!

[Q] So..I have a problem with going back to my factory rom

I need to make a warranty exchange, but if I send my phone in, and they see its rooted, Im going to get an out of warranty fee.
Its not letting me recover to my back up. Im completely lost as to what to do. I need to make it look like Ive never rooted my phone at all

You don't really expect to get much help with so little information, do you? What recovery and ROM do you have installed? How are you trying to go back to stock, a nandroid backup?

Sorry. Guess thats kind of important. lol
Recovery: 3.0.0.5
themed ice glacier 1.1.4
And form what the person who rooted my phone told me, that I now cant get a hold of, I just install from backup that he had originally made, when he flashed the rom. Sorry. I know Im a noob. Been extremely busy to actually learn. Go figure the guy whos been helping me, hasnt been answering his phone

CWM 3.0.0.5 can only flash Gingerbread ROMs, and the stock image you're trying to restore is a Froyo ROM. All you need to do is switch to CWM 3.0.0.6 and you can successfully revert back to stock.

1. Go here to install this CWM version, which will allow you to flash 3.0.0.6 and older CWM, which you need to go back to stock nandroid restore (http://forum.xda-developers.com/showthread.php?t=944681).
2. Go here for how to restore stock nandroid (http://forum.xda-developers.com/showthread.php?t=845756). Make sure you flash older CWM recovery when restoring stock nandroid. After restoring, you can follow thread and instructions to turn S-on again.

You do not need to use any recovery other than 3.0.0.6 to restore the stock nandroid image.

Awesome. Thanks man. Time to go bleed magenta. Hahaha

[Q] Question about root and recovery

I've searched the forums without any luck. Anyways, I have a question about root and recovery. Yesterday I rooted my phone using a guide from the unlockr. All went well and my phone is now rooted. I want to install a new ROM on my phone and I keep reading about installing "recovery" before the ROM and I'm not sure if I've done that? Is there a way to know if I have installed the recovery or not?
Oh wow I'm stupid. On the guide it says I now have root access and a recovery image. My bad. But now I have another question; If I don't happen to like the new ROM is it easy to just go back to normal, like factory settings?

First Question
It's quiet easy.
- If you have rom manager installed, you have clockworkmod recovery installed.
- If not, try to power on your tattoo with the touches "home" + "power" until you go on the recovery. If you go on the recovery, you got it! ;-)
Second question
Before flashing a rom, do a Nandroid backup in the recovery so you can restore to your current rom with all yours data.

I have the clockwordmod recovery v3.0.0.5 and I started the phone by pressing home+power and I hit the "Backup and restore" option but there's no "Nandroid backup" thingy, all I see is "backup" or "restore", is that the same thing?
I'm running a backup right as we speak.

Yes! the backup & restore menu are the nandroid backup & restore...

Okay, thanks! The backup is done and I'm now copying the clockworkmod folder to my computer, and soon I'm gonna try flash the nFinityGB rom
cross your fingers! lol

Well, I copied the nFinityGB.zip-file and put it on the SD crad, but when i try to start it in recovery mode it gets stuck on "Tattoo" on the screen. What am I doing wrong? lol

to install the rom, you have to go in the recovery. did you push home + power buttons as well during the boot?

Yeah I did, I fixed it though by doing the root thing again, dunno why I couldn't start the phone in recovery mode. I have the nFinityGB rom now though, looks pretty awesome
Thanks for your help btw!

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?
