Official T-Mobile MT3G Roms??

Is there such a thing? Say, if I wanted to revert back to t-mobile's stock.
Is there a 1.6 rom/update? OR a 1.5 that can update to 1.6?
I lost my MT3G's stock nandroid backup (Face-Palm!) and now I don't know what to do...

You would flash the RC29 for stock then wait for tmo to update your phone with 1.6.

Thanks so much for the reply!
I searched the forum and Google, do you or anyone know where I can get the MT3G RC29 build?

Follow the to unroot MT3G.

Hey, you can flash this sappimg.nbh forum.xda-developers.com/showthread.php?t=547133 to get back to stock 1.6. Then update to 1.6 by going into recovery mode by holding home +power when the icon comes up hit home + power again to get to the options. I'll post a link to the 1.6 update in a second.

Alright, cool. One last noob question. Will this wipe and restore everything (data, recovery img, etc)?

Okay, thanks for the help. I'll post how it goes when i do it.

unroot using only sd card?

Ok so My phone is not recognized by a computer, i have tried different drivers, cords, ROMs, no matter what I do my phone is not recognized. I took it to the sprint store and the tech there who also has a rooted hero couldn't get it to mount either, the phone just doesn't bring up any mount notification at the top. I have a nandroid backup with stock ROM but even when I do that it is still rooted, they will not give me a new one until it is unrooted. My only other option is to make an insurance claim since I cannot flash it back to stock.
My Question: Is there any way to flash to stock and get unrooted using only my SD card (I can plug it into my card reader and it works fine). Thank you for any help you can give.

Sorry to report, the only option of unrooting is RUU, and this requires HTC Synch and a definate recognition on your PCs part.
Suggestions, anyone?

What version of Windows are you running? I have had issues with Windows 7 in the past. As weird as it sounds once I loaded PDAnet from the market on to my phone and the PDAnet client onto my computer. My phone was recognized. Is your computer charging the phone when plugged in?

its possible.. but you'd need Flashrec, an unrooted original 1.5 rom, and the original recovery image..
ie: use the custom recovery to flash the unrooted rom, then flashrec to flash the original recovery image.. then remove flashrec..
just an idea!

This brings up another question....
What does Sprint actually check?
Do you really have to get back to 100% stock, or would putting the original recovery image on get you through?
Any current or former Sprint techs willing to chime in? Just how perfect do we have to get it?

Actually, that just might work! Great idea chavo, very intuitive thinking!

I take back my last statement. I read somewhere flashrec doesnt work after youv flashed your imahe....google the unlockrs method on flashing a new recovery once already rooted; i think it involves some adb though :-(
Idk, thats as much as i know

I know it works.. but I have an unrooted rom in a nandroid backup from when rooting the Sprint Hero first started.. lol not many people have those laying around, as most used the Asroot2 method of rooting and not Flashrec to flash the recovery.

Your nandroid wont work on another phone, and if it did, it would synch your contacts to their phones, passwords, apps, the whole shindig. Bad idea
We'll have to beg a dev for a stock 1.5 rom

you can use a nandroid from another Sprint Hero.. done that too when i got my replacement phone! If anyones willing..
RUU, don't sign into google. Download and install Flashrec and flash the recovery through that and create a nandroid backup.. it will be clean

Once again, very intuitive thinking! I thought maybe nandroid was device specific.
Sorry, no way in hell im RUU'ing after all the bricks. Ill stick with dcv2, its stock enough for me

Nandroid is device specific to a point.. If you go in to the nandroid folder on the SD card you will see a folder labled HT********** that is specific to your phone, however you can take a nandroid from another phone and place it in that folder and backup from that.
i'd do the RUU but i'm using the updated radio.

I use a mac, but if indeed it isn't the windows driver, and you have tried other roms, then it only leaves the kernel (and the usb cable and phone usb hwd ).
So use what ever methods you used for the rom flashing, and flash a kernel.
Some ideas : http://forum.xda-developers.com/showthread.php?t=625940&page=1
( start at page 1 )
Just a thought.

isn't the nandroid image made right AFTER you root?
so then, that wouldn't be what you want.
Extract the stock rom from the RUU

ok.. here's an unrooted 1.5 Nandroid back up.
http://www.4shared.com/file/250722598/a6eddc31/NoRootNandroid.html
Download the zip, extract.. and place the folder NoRootNand on the SD card in SDCARD/nandroid/HT**********/
Boot into recovery, select restore as you would if you were restoring a backup you made -->Nand Restore-->HT**********--> and choose to restore NoRootNand
I'm using the RA-heroc-v1.6.2 recovery, so I am unable to verify if this is will work with an older recovery image.
if you have any questions feel free to ask.

Wow thank you everyone for all of the advice, i had all but given up hope since I had been all over google looking for an answer for about 2 weeks. I will try the nandroid backup above and report back. thank you everyone again, you may have just saved me an insurance claim.

Wow, glad I found this thread. I'm downloading that nandroid image right now because I'm going to probably end up taking my Hero in to get the dust cleaned out later this week. I think another option would be to extract the RUU and get the ROM.zip out of it, and then just flash that.

Ok I tried this and I am still rooted afterwards. I think that if you go to the sprint store and they can hit volume down and power, and get to the recovery menu then they will not take it back, no matter if the rom u are running is stock or not. any other ideas?

Slide stock nandroid backup

In case you need to revert for warranty service or just for fun.
Taken from a never before booted unmodified unit. Enjoy!
http://www.4shared.com/file/T0ekY2XN/mytouch_slide_factory_nandroid.html
Note: These instructions assume a certain level of technical skill considering if you have the need to revert you have already rooted and flashed your devices at least once. Ensure you have flashed the factory version of the radio and splash1 partition prior to returning to this image for everything to be factory (note: splash1 can currently be nothing other than factory as there is not an SPL with security off at this time).
1) Unpack these files to your phones sdcard in to a directory named: clockworkmod/backup/factory
2) Boot in a ClockworkMod Recovery
3) Select wipe data/factory reset
4) Select nandroid; restore; select the directory named factory ; wait for restore to complete
5) Reboot

thanks for this. but noob question here: if i ever root & go flashin roms all willy-nilly, how would i apply this?

Nice. Thanks.

Thanks man, I'm gonna keep this saved on me PC for that "just in case" moment you might need it haha. Appeciate it.

Curious if anyone has performed a nandroid restore with the Slide via the stock/clockwork recovery method. My thinking here is if a nandroid restore is possible, with this backup we can return the phone to an absolute un-rooted stock state. Is that correct? Any insight is appreciated.

If you flashed the engineering rom make sure you apply the Newest_Slide_Radio.zip that ChiefzReloaded posted, that is the stock radio. The nandroid backup does not contain the radio.

Interesting, 3 posts asking for clarification and the OP provides unsolicited clarification for someone simply posting a thanks.
Thanks for posting the Nandroid files.

Im going to try and do a nandroid backup using this, but not until tuesday of this coming week (when i will be returning the phone to Best Buy ;-) )

Update.zip?
How do i restore this backup, rename it to update and flash from the normal recovery, i have a mix of the original rom and the engineering rom preventing root (lost clockwork by not installing the SU.apk during the Eng flash). i need to take it back, anyone out there???

You need to get in to clockwork recovery, which is currently loaded by the update.zip you use to root your phone. Once you are in there you select nandroid and restore, then flash these backup images to your phone.
If you get to the point you need to do it I would be happy to provide more detailed instructions!

You need to get in to the Clockwork Recovery to restore this. Follow the directions in the root how-to, when you apply that provided update.zip that is what gets you in to clockwork recovery.
Copy these files on to your sdcard (first, before anything else), get in to Clockwork Recovery, select nandroid, select restore, and point it to these images.

ok this sounds totally noob but I'm not sure what you mean by "point it to these images"

[Q] How can I backup oficial Desire Z rom etc.?

I am going to have my new Desire Z in a few days and I want to root it. I have a question, how can I backup all of oficial rom, kernel, radio ets.?

Well you're going to have to downgrade in order to get root, which will wipe the device as far as I know.
After you've downgraded and rooted, you can then use ROM manger to make a 'nandroid' backup of the device. It effectively makes a perfect copy of the entire device, and saves it to your SD card. After you flash a new ROM or anything, you can always go back and restore that nandroid backup, putting you exactly where you were when you made the backup.
It should be noted that when you send it into HTC for repair, you'll want to unroot it anyways, which will wipe the device again and return to stock w/ S-ON (you dont want to send it to HTC with your info on it anyways), so keeping the stock rooted ROM isn't completely necessary (although it is a good idea to have around for troubleshooting reasons).

3) I need to S-ON my device again when sending to HTC.
4) The mst important is saving nandroid backup will save my device
Are these true or will i have to study more?
By the way, I want to try sense 3.0 but i am not sure to have virtuous rom. do you recommend to get it? Which is best; to have a gingerbread rom w/ sense 2.1 or froyo rom w/ sense 3.0? As i know, virtuous rom doesn't have gingerbread now but it might have soon...

Yep you got it. After downgrade/rooting (follow Wiki guide), use ROM manager (download in the market) to flash ClockWorkMod Recovery. Then use that to make a backup. It saves the file to your SD card. Copy that file to your computer for safe keeping (good to have it in 2 places if you really wanna make sure you keep it).
To get S-ON later if you need to send in for repair, follow the Wiki to unroot and that'll be done. It should be noted that unrooting the phone will flash it back to completely stock setup, so the stock nandroid backup isn't necessary to keep in order to send back to HTC. The only real reason to keep that rooted stock backup around is for troubleshooting problems, etc. you can always go back to the stock ROM to try things.
As far as running Virtuous for Sense 3.0 or 2.1, that's all personal preference. I advise just trying different ROMs and seeing which you like. Everyone likes something different. Just remember to nandroid the one you're on before switching so you can go back if need be.

I was just going to make a post about the same subject until I saw this. I also too want to back up my G2 stock rom. I'm currently returing my old G2 inplace of a replacement G2. I want to know how I can back up the stock rom without rooting? I downloaded rom manager but need root to continue. My old phone was rooted and had all my backups that way. I wanna try out the new 2.3.4 from OTA when I get the notification to do so, but just incase I don't like it I wanna go back to stock then root. So how can I do a full backup without root or doing a factory data reset? Thanks

The only way to do a full backup is to root and use ROM manager to make a nandroid backup. Like I said before, backing up the stock ROM is nice for troubleshooting etc. but in order to un-root you'll have to completely wipe the device and will install the stock ROM again.
If you want to try out 2.3 you can use CM7 (which is stock 2.3 w/ some improvements), or wait for the official OTA to be pre-rooted then you can flash it after you've rooted.

Yea sorry for the confusion if I made it sound that way. The action of un-rooting the device will put it back to stock, you don't have to save the stock ROM. The only reason to do so is if you like to have the stock rooted ROM around just in case you want to try something on it.

[Q] Unrooting for 2.3.4 update, but first....

Ok, so I want to get the update for my MT4G, but I'm currently permrooted with s=off (used visionary), and I used gfree to get the universal CID and unlocked SIM. Then, I installed one of faux123's Sense kernel's for some performance boost.
I've done a nandroid backup of my current phone, synced my contacts to google, written down all my apps and backed up most of them to my SD card.
SO, now I want to go all the way back so that I can take my phone into the store and have them install android 2.3.4, and that is where you all come in:
Q1: What exactly is my first step? Get back to a stock kernel? Or just go straight for unrooting?
Q2: Do I need to flash a stock kernel back onto my device? I have a nandroid backup from before I flashed faux123's kernel, if I restore it, will that take care of it?
Q3: If I nandroid restore a completely stock backup (this one http://forum.xda-developers.com/showthread.php?t=845756), will that take care of the universal CID, unlocked SIM, and engineering bootloader (basically, is it a one-step solution)?
Q4: I have 2 unroot guides, and I want to make sure that I'm doing the right thing. Assuming I can get back to a stock kernel (see Q2), will this guide (http://forum.xda-developers.com/showthread.php?t=924923) suffice to undo everything I did? Or do I need to use a more technical method (like this http://forum.xda-developers.com/showthread.php?t=863899)?

If you go to the tmo store they use an sdcard with the update on it and if you update you will lose your root. Right now there is no way to root 2.3.4, that been said the update that is on that card has been uploaded and posted on here http://forum.xda-developers.com/showthread.php?t=1217237 and you can download it and install it yourself with s-off. I am running it right now with s-off

If all you want is the update, but wish to keeprl root and cid unlocked then just flash the the leaked ROM and you will have the 2.3.4 ROM and kernel all in one easy process... Now, I know you said that you backed up your apps and such on the sdcard, but when changing ROM bases it is not wise to restore system app data. Just a thought... If you wish to lose root and retain sin unlock then take the phone as is to the store and let them flash the ROM for you... It is an ruu file so it will replace the the bootloader, radio, ROM and kernel... The don't care if you are rooted as you will lose root after the flash your phone.

I didn't know that, so it's better to delete all the apps and system data from the SD, then re-download each app and reconfigure manually?

It's better to back up only user apps and PIM data, reconfigure the system from scratch, and reinstall user apps with data and PIM data back.
