Hi I have read posts about backup using Nandroid on 32a for system and data. so how about if i want to backup the original recovery img before flashing it to cyanogen's or RA's?
Thanks in adv.
Bump
anyone?
thx in adv
if im understanding correctly all you want is the original recovery, you can download it as the .img file then just save it to your computer and install it like ra/cyan if you ever want to go back to it
you wouldn't necessarily need to make a backup of it just like you don't need a backup of the original android software you can download the ota releases and install them like a rom
the reason it has the back up is to keep your last working rom in case you install one with problems
I hope that helped I tried to answer the question a few different ways for you
One-Click-Root method.
The application, "Recovery Flasher" can do exactly what you desire. Although, if you're currently operating on the 1.6 firmware; you'll need to "back track" to 1.5 and go about the rooting process normally.

First, thanks for taking the time to read this. I appreciate that these forums get a lot of frustrating posts with people asking questions that have already been answered, and it is not my intention to do that. I have been lurking on these forums for a while, and have read around quite a bit of information. However, I cannot find the exact answers I am after.
To start, I am now on my 2nd HTC Magic 32B (Voda UK), after I sent my initial phone off for repair. I was running Cyanogen Mod on this phone, and flashed this rom by fastbooting in to Cyanogen's Recovery and going from there.
I was careful to take a nandroid backup before I flashed, and as such, when the time came to said the phone off for repair, I was able to restore the backup and send it off with the stock firmware running.
Unfortunately, the phone I have now received has a 'perfect' SPL, HBOOT-1.33.0007, so I cannot flash a rom using the same method.
My primary concern through all of this, is finding a way to flash roms such that I can revert everything back to normal if the need arises.
I have read around 1-click rooting, so, my proposed method at the moment would be:
1) use Flashrec to boot into Cyanogen Recovery
2) Backup using nandroid
3) using adb shell to flash Cyanogen Recovery
4) use Cyanogen Recovery to flash rom
I should now be in a position where I can a) flash back to the original recovery if needed, using the backup from nandroid, and b) flash back to the original rom if needed, using the backup from nandroid.
Would this work as I hope?
I have read about having to 'downgrade' the SPL when wishing to restore a nandroid backup, but I did not need to previously. What are the circumstances where you do need to? - I would not want to do this, since I have no way of flashing the original SPL back. I presume there is no way to backup my SPL? so I could return to it if need be?
Thanks for taking the time to read this, and I appreciate any help you may be able to give me.
Cheers.
I have a Rogers 32A that had a Perfect SPL (1.33.0010) on it and I got a rooted recovery ROM by using One Click Root. The Perfect SPL wasn't allowing me to fastboot at all (giving me a "no access" error or something). So instead I booted running the stock software, and used the one click root program to backup my ROM and then flash a recovery ROM (used the default Cyanogen Recovery 1.4). Then when I rebooted while holding down Power + Home, I came right into my rooted recovery ROM where I could install whatever .zip ROM I wanted (AFTER I BACKED UP WITH NANDROID, of course).
I didn't need to use ADB for anything, and I still ended up with root. So I guess I'm confused when you say you're going to use flashrec to boot into cyanogen recovery and then use adb shell to flash cyanogen recovery. I was under the impresion that flashrec FLASHES cyanogen recovery for you, eliminating the need to use ADB/Fastboot. Assumed "flashrec" stood for "Flash Recovery ROM".
My steps were:
1) Install/run flashrec
2) In FlashRec: Backup your current ROM
3) In FlashRec: Select a new recovery ROM to Flash (has Cyanogen's by default, can change to something on your SD Card)
4) In FlashRec: Flash the Recovery ROM
5) Exit FlashRec and reboot into Recovery Mode (Hold Home and Power)
6) You're done, you have a rooted phone. Go ahead and Nandroid a backup, wipe your data, and install a new ROM.
Thanks for your reply.
It is my understanding that flashrec does not flash the recovery rom, but just allows you to boot to it. (Similar to the fastboot boot filename.img command). I would guess that if you reboot your phone using home + power now, that it would boot to the standard recovery.
If it is the case that flashrec does flash the recovery image, then that would be handy, and presumably the backup could be restored using either nandroid or adb.
Thanks, this clarifies that my rooting procedure is along the right lines, however I am still concerned whether flashing everything back to normal will go as I expect.
Just booted into recovery, and its still CyanogenMod v1.4 + JF.
I'm trying to think if I did anything special during my rooting efforts. I don't think I did. I know that I flashrec'd twice. the First was with Amon_Ra's recovery console, and then I did it again a bit later with Cyanogen's. But I'm positive I was never able to successfully use adb's fastboot command due to my perfected SPL.
And you're right, I didn't address your concerns about unrooting at a later date. I assume that is what you're doing when you use flashrec to create a backup of the stock Recovery ROM, but i'm not positive.

EVERY TIME YOU REBOOT YOUR PHONE INTO NORMAL ANDROID IT UNDOES WHAT YOU JUST DID. Every time android boots, it reflashes the recovery partition with the default one from a file stored in your phone. For safety reasons, we are not replacing this file – just flashing the partition directly. So if you boot to recovery mode, then boot back into your normal mode, and then boot back into recovery mode – you will see a triangle with an exclamation point and only 3 options.

So I'm not sure what's going on.
Thanks for your input. I think I'm nearing enough confidence to go ahead and give this a try. Probably tomorrow.
Hi ParanoiaPersonified - can you post an update when you flash? I also have a new Voda Magic with the same SPL as yourself.....I got the OTA upgrade to Donut yesterday which I may have been silly about accepting.
I wasn't too impressed with the speed improvements in Donut and now want to flash something built by one of the XDA chefs, but am having problems rooting with the traditional methods - even 1 click doesn't seem to work....
Cheers.
It is my understanding that one-click-root only works on 1.5, and the exploit that it uses is patched in 1.6. I think you may need to use the 'gold card' method, radita.
I've realised that my handset has a fault (the scrollwheel does not work when scrolling to the right), so I will be unfortunately waiting for a replacement handset before taking any of the steps mentioned above.
Hopefully the replacement does come with 1.6 pre-installed!
"Gold card" method looks a little more involved....guess I don't have a choice though.
Thanks.
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.
I'm just starting to read up on how to root and flash my phone and also how to go back to stock if necessary. If you haven't rooted your phone yet, is there any method to fully backup the phone so that returning to stock is easier?
Thanks!
Use the backup function in the recovery or use an app like MyBackUpPro full version.
Questions should go in the questions section.
Backup option in recovery for sure. This backs up your whole phone state. Apps, settings, icons...everything. For an extra safety measure you can use something like Titanium Backup to backup apps and system settings. This is good for switching roms.
you can use the backup from ROM Manager and if you really need to you can always follow the unroot procedure and that gets you back to the out of the box feel
Thank guys. Sorry for posting in the wrong forum, I thought ROM/flashing questions belonged here...
To backup from recovery or ROM manager you need to first flash over the stock recovery image with ClockworkMod Recovery, correct? I was wondering if there's any full backup that will also backup the recovery image prior to doing this, for an easy return to fully stock phone. I'm guessing the answer is no. Correct?
Thanks!

Once you have rooted the phone, and turned s=off you can flash Clockwork Recovery image to do back ups.
IF you are needed to go to a 100% stock fashion for what ever reason. you can do that. All you need to do is download the PD15IMG which can be found in the development section. Store it to the SDcard and boot the phone into boot-loader. That will replace EVERYTHING and put it back to a 100% factory spec. and no they cannot tell it's been rooted once the PD15IMG has been flashed.
Thanks for the info. That about covers it.
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.
Hy,
I have two i9505, I read a lot and installed CWM using Heimdall, I flashed SuperSU to gain root, and made a backup. It labeled the backup with an outdated 1970 name...
I took the SD card out to copy the SD backup, but could find it even when searching for hidden folder.
I put back the SD card in my device, and booted to CWM, the backup was available for a restore process. So before trying any flash I tried out a restore process, but ended up with a stuck in boot. Boot to CWM and bootloader being still available, I managed to flash a workable ROM, but I can't restore to my initial ROM.
Now, I'd like to be able to restore my device to it's initial ROM.
I believe that somehow, the backup I made is corrupted.
As I have another identical i9505 I haven't tempered with yet, I guess I could install CWM (or other custom recovery) to make a backup of the ROM, extract the backup of the ROM from the SD and use it to 'clone' my second device ROM to this one.
But I don't wan't to make any mistake here, so I'd apreciate some help, first to understand where CWM put the backup .tar.
Another solution is to get some stock ROM I can flash. As anyway I don't have any warranty on the device I don't care to restore to exact initial state, I just want to be able to get back to some stock ROM.
sammobile.com/firmwares is the place to go if you want a stock ROM. Download whichever ROM you want, then use Heimdall to flash it, and you should then be returned to stock. For best results, the ROM you download should have no carrier branding, but any of them should work.
I though I would have to do something like that from reading the unroot guide. Also, as I use Heimdall to flash (I have a linuxBox), I will use this guide in french as a guideline.
I noticed that the command line they recommend don't flash sbl1. I don't know if it is required.
Thank you anyway for confirming that.
