Question about unrooting and restore stock - myTouch 4G Q&A, Help & Troubleshooting

Im currently running Iced Glacier 1.1.6 with CWM recovery 3.0.0.5
In order to fully restore the phone to stock, meaning stock recovery, bootloader S-OFF and stock rom, dom I first restore the stock recovery or does the fastboot image loader restore eveyrthing to stock (as described in this method http://theunlockr.com/2010/12/16/how-to-unroot-the-t-mobile-mytouch-4g/)
I need to know because I might have to send in my phone for some repairs and want everything to be stock so they dont say anything about warranty voids.

there is a thread in the development section with the PD15IMG.zip file...
http://www.filedropper.com/pd15imgglaciertmous1175312radio1228b60140e26030226mrelease155771signed is a link to it...rename it to PD15IMG.zip and place it on the root of your SD card...power off the phone...turn it on by holding the vol down and power button...let it do its thing

Rooting 32B Magic 'Perfect' SPL, whilst ensuring it can be returned to stock

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.

can someone post a link to where i can get the 2.3.1 update?

after the i got the 2.3.2 update, the phone just sucks. it's annoying the hell out of me. is it possible to manually reload the previous update if i have a stock phone. i'm assuming i just need to put it on the internal memory and restart the phone holding the volume up and power button, right?
In the development section there's a Nandriod backup of 2.3.1
You just need to install clockwork recovery. Copy the backup to the SD card and restore via clockwork. The restore will also flash back to stock recovery.
Follow the guide, also in the development section, on how to root without unlocking bootloader. Use the method described in there to run clockwork.

[Q] Help Please recovery problems rooted stock rom

Okay, so where to start...
I have a MT4G (of course) i love it dont get me wrongand wanted to mess around with it. i permarooted it via VISONary + and everything was working fine. i wanted to flash a different kernal and wanted to do a nandoird backup before i did anything else. but i needed clockwork to do this (correct me please if im wrong) so i downloaded rom manager flashed it. and went to boot into recovery and it does this icon with a phone and a "!" on the screen...it cant boot into recovery. and i dont know why, and now i just want to go back to my stock recovery but i cant cause i dont know how. ive tried terminal commands... and i tried to learn adb and fastboot but am very lost. basically i want a nandroid of my rooted stock ROM... any help would be much appreciated
The reason is because you need to turn s=off for any of those to work.

Read the guides.
1. The phone with the red triangle icon is from the stock Recovery program. Stock recovery does nothing except show you that screen, unless a special file is found on the SD card, used for a complete system restore. Your flash of ClockworkMod Recovery was unsuccessful.
2. When you do go get past the S=Off phase, and are ready to once again attempt to install CWM Recovery, be sure you install the CORRECT version. CWMR 3.0.0.5 is for Gingerbread (Android 2.3) based ROMs only! Don't install 3.0.0.5 expecting it to function properly for the Stock ROM, for Iced Glacier, or any other Froyo (Android 2.2) based ROMs. Those all require CWMR 2.x. A higher version number does not mean better. For example, if you are planning to install CM7, back up with CWMR 2.x, then flash CWMR 3.x before installing CM7.
(There is a special, unique to MT4G version of CWMR that handles both Froyo and Gingerbread ROMs, called "3.0.0.6". You can find threads on it in the Development subforum.)

[Q] Do I have a brick?

I was running CM7 RC3 fine on my phone, then I decided to switch back to my nandroid backup to stock ( I have done this wil ICed glacier/CM7 RC2/RC1/Royal Ginger etc with no problems). And I have been stuck on the boot splash screen the "Tmobile Mytouch 4g" screen for 20 minutes now without any action... is this a brick? I know I should not worry, but I tried wiping the dalvik cache the acahe and reset to factory setting.... still nothing
How do I go about getting the phone to work?
Thanks
are you running recovery 3.0.0.6? have you tried a battery pull?
Yes, a battery pull was tried, and I am running 3.0.0.5... any help is really appreciated
How do I possibly install 3.0.0.6 now? is it possible?
Thanks
need 3.0.0.6 to run stock or royal glacier. or 2.5.1.2. need to reinstall cm7 and use rom manager to flash recovery. or at least its the eaisest way for me.
follow drews guide and let us know how it goes. http://forum.xda-developers.com/showthread.php?t=944681
unfortunately, I am not being able to go back to royal ginger (its on the toyal ginger splash screen now) I am downloading CM7 RC3 again, but have no way to put it on the sdcard coz I do not have a card reader at this point....... so frustrated.
you can use recovery to mount usb and it will mount the sd card and can tranfer files from computer to card. if you can get to recovery its not bricked. make sure you format boot sys data and cache in mount screen before trying reflash.
Push the cwm 3.0.0.6 recovery image to your phone via adb

Google easy way to get 3.0.0.6 and it should be a zip file u flash in recovery called clockwork_recoveries.zip or something like that. You go into rom manager pick all recoveries and flash 3.0.0.5 and reboot into recovery and it should say 3.0.0.6 now u can flash any rom and restore without getting stuck

Your phone is not bricked. As others have stated, you need to re-flash a gingerbread ROM (like CM7) in order for it to boot.
Best thing to do is install ClockworkMod Recovery version 3.0.0.6 because it can flash both gingerbread and froyo ROMs. You can do this in two ways:
1. Re-flash a Gingerbread ROM. Download TrueBlue_Drew's .zip file from his thread in Development and follow his instructions to be able to flash the included recovery images from ROM Manager.
2. If you have the engineering bootloader (0.85.2007, also some people call it ENG SPL), and if you've set up ADB on your computer, then you can use the fastboot utility to flash recovery images directly to the device. I personally prefer this method. If you can't find instructions to do this, PM me.

[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
