Revert Back To Stock On MT4G - myTouch 4G Q&A, Help & Troubleshooting

Hi i bought a mytouch 4g wanted to know if theres a way to return back to stock would i download the rom from tmobile and boot into boot loader...screen???thnx in advance

I just answered this for someone else in this thread, specifically this post.
Good luck

i see the thread but my question is how do i know which root i have so i can unroot

All rooting methods accomplish the same thing: setting S-OFF, (usually) flashing the engineering hboot, and installing a su binary to give you root permissions in the OS.
As to "how" your phone was rooted, with gfree or visionary/rage, only you (or whoever you bought it from) would know that.

Unroot Unrevoked after the OTA?!?!?!?

Seriously? I can not find anything for the life of me!!! Has ANYONE found a way to unroot Unrevoked 3.21 if rooted AFTER accepting the OTA (3.29)??? If unrevoked puts out a root exploit without telling anyone how they obtain root, why wont they provide anyone with how to unroot it? Seriously make me so irritated because I see a bunch of people who rooted with UR3 and now need to unroot for various reasons; however, it seems almost impossible at this point...
I know there are a lot of people against unrevoked but nonetheless this is still a PROBLEM the needs to be RESOLVED.
Anybody have any answers or solutions?

From what has been said in recent posts the RUU does not work nor does the pc36img that was posted in the 2 step unrooting guide in the devolopment section.
From my experience in doing this, you need the Unrevoked S-ON tool, which you can find here.
I have found that downloading the RUU and running it twice tends to solve the problems.
I think it might not connect to the bootloader on the first time, just run the RUU again and it should work it's magic. I would recommend a full wipe of system/cache/dalvik-cache after applying the S-ON tool and then running the RUU.
EDIT: This will revert your entire phone to stock, so don't do it without knowing that it will cause you to lose root and possibly not gain it again.
Whoops... posted in the wrong spot.

I used the above guide to restore mine back to factory BUT the guide is mistaken on steps.
You WILL need to preform all steps regardless of the style of root. At least thats what it took for me to get back to stock.
Forget the red text and start at #1 and work to #15 for success.
Once unrooted you will be at the version prior to 3.70 and then you will get the OTA update to bring you current.

What is the end result you are trying to get to?
If you are wanting S=off so you can flash custom ROMs.
http://theunlockr.com/2010/12/10/how-to-temporarily-root-the-t-mobile-mytouch-4g-htc-glacier/; do that and it will lead you to perma root the easy way.
if you are wanting s=off so you can have complete control over your phone, which will enable the possibility of a brick. including SuperCID, ./gfree and some other goodies...... But this will give you the option to severally screw up your phone including up to a 500.00 paper weight.

If you haven't screwed up the HBoot and the bootloader you can use this to get back to a factory spec.
http://forum.xda-developers.com/showthread.php?t=863899&highlight=level
But if this is your first android, and your first time rooting i would HIGHLY suggest doing alot of reading before you jump in head first. There are alot of people who have tried to do and get stuck. This phone is confusing once rooted with 2.2 ROMs and 2.3 ROMs and different recovery images you need to read and make sure you understand everything before jumping in feet first.
Temp root with visionary is the easiest and safest way, but gfree is pretty simple as well. The hardest bit is getting the drivers and ADB to work, and thats not overly difficult. (remember to use the command "ADB devices" to know if the drives are working) It just matters what you plan on doing, stock root or custom ROM.
There is really only two points that risk a hard brick, flashing the radio or hboot.
The gfree method does not require either, but you can flash the engineering hboot as optional.
The biggest thing with recoveries and ROMs is know that gingerbread based ROMs (like CM7) use ext4 file system and froyo ROMs use ext3. So it is important to use the right version of Clockwork recovery. Use v2.5.1.2 for froyo ROMs and v3.0 for gingerbread ROMs. Soon clockwork mod will support both on the same version.
Just read the instructions well and have all files downloaded and ready to go.
If you want to use gfree and a custom ROM, there is no need to get perm root on the stock ROM first. After the steps that get s=off, just run visionary as temp root with system r/w access and install ROM manager from the market, then use ROM manager to flash a new recovery. Reboot into recovery backup your stock ROM then flash a new ROM.
If you never touch the hboot or radio firmware, then at worse you can bootloop or soft brick the device. That can be fixed with varying amounts of work, depending on the exact issue.
Read and learn how the different parts work, learn how to use ADB and you will be better prepared.
newbie here
This is my first post. I would really appreciate anybody helping me out here. I can't seem to get any straight answers, or answers I can understand, anyway, so here goes.
I have an HTC Mytouch 4g. I did a temporary root (using the method at theunlockr.com) and uninstalled the monopoly app. I was going to uninstall a bunch of other stuff but I got nervous and did a factory data reset (in the SD & phone storage area). All of my marketplace apps reinstalled, which I thought wasn't supposed to happen, but anyway.... I did the volume down/power on and see now that my phone is GLACIER PVT SHIP S-ON. So my question is how to interpret the state that my phone is now in. Is it factory? Is it rooted? Will the T-Mobile OTA updates work? Why is the monopoly app still gone? Is my warranty voided?

Temp root is just that, temporary. It creates a copy of the essential files in the system partition that it runs from rather than the actual system partition. If you allow it r/w access, (an option you can choose when using visionary) it can uninstall apps that normally can not be. (and more, but causing big changes would require more work on your part)
Because it is temporary, there is no need to get nervous. Unless you are doing some major changes, ones that need a root explorer app or terminal emulator, then you can't really hurt the phone. Download terminal emulator from market and run it, then type in the super user command "su" (no quotes) then hit enter, if the cursor changes to a # symbol then you have root. (you may get a popup asking for root permission, choose to allow) If it works after a fresh reboot, you either ran perm root in visionary, or you have the option checked to temp root every reboot.
S-ON means that the bootloader security is still in place. You need it off to install custom software. While you can root the stock software with S-ON you can not install any software that has potential to brick your phone, so no need to worry at all. If you are really that worried, keep a copy of the stock software on your SD card. Make sure it is named PD15IMG and at any time you get nervous, you can boot into hboot (the bootloader) and it will run automatically. It will wipe your phone and return it to complete stock. The irony is, that flashing this stock image file does things that can brick a phone if it goes wrong. It flashes more than just the OS, it also flashes hboot and recovery as well, and if the process is messed up in anyway like loosing power at the wrong time, it can brick the phone.
Really as long as you make sure you have the phone charged and you follow instructions you should be fine. The only times you can brick a phone to the point it can not be brought back is when flashing hboot and the radio firmware. Both of which you would rarely flash. Hboot only needs flashed to the engineering version once (OEM testing/DEV version) and only if you choose to, as it is not required. The radio will only need flashed if an update for it comes out, and that isn't often, and it is rarely mandatory.
The chance of truly bricking your phone is not very high, unless you just can't follow the directions. Now you can put it into a bootloop or soft brick it. (bootup stuck on mytouch screen) But if you can boot the phone into hboot (vol down + power on) then you can fix it. Even if you can not boot into recovery (an option in the hboot menu) you can even fix that with a good hboot.
theres a video on youtube by mackster its awesome and it gives you all the links very easy to use.
it wont let me post the link but just search root mytouch 4g on youtube and it should be the first or second one.
Thanks Marine and Tommy.
So with temporary root, as soon as I turned off and then back on the phone, it was back to its unrooted, original state, minus the T-Mobile application? Will I now get T-Mobile's Over the Air (OTA, right?) updates and not have a problem if I need warranty work?

Uninstalling an app will not hurt anything. OTA updates will still work fine. You can temp root and then perm root the stock ROM and revert easily. Heck, even perm rooting stock doesn't break OTA I believe.
Voiding the warranty is one of those grey areas. As long as you can revert to stock, then they will never know. Temp root does not void warranty at all, because you do not alter the system files. (unless you want to, and enable the ability to read/write system) Just uninstall terminal emulator and super user apps and there is no evidence.
The only time you might get caught, is if say the screen stops working, and you can not see to revert back. Though even then, just putting the stock OTA image on the sd card then booting up the phone in hboot will restore without needing to actually see anything. It does ask for confirmation to restore, just wait several minutes then hit the power button and it would do it on its own.
The set of circumstances needed to prevent you from restoring to stock, are rare. Basically a borked hboot or radio firmware, and you never need to touch those to get full root and custom ROMs. If you never touch them, the chance of issue is almost zero.
I just got my mt4g and I am looking to root my phone for the following reasons:
apps2sd
remove bloatware (I want the app to be disabled and I don't want the icon in my app drawer)
use adfree
I don't want any custom roms and I'd like to keep sense ui.
Can anyone tell me if this is at all possible? I've read around and I know it's possible but I don't know about rom flashing and I'm confused as to whether or not I need to flash a custom rom? What's the point of a custom rom anyways?

You dont need apps2sd, as the mytouch 4g has Froyo installed, and you can move some apps to the SD card. Just go into settings-Applications-chose the applicaiton you want on your SD card, and look for "move to SD". If it's grayed out, then you cant move it.
Also download appfreezer from the market, and just "freeze" the bloatware. That's what I do, and it gets rid of those annoying looking apps they installed.
Question about clockworkmod
OK i just rooted my phone, flashed the rom, and installed all the goods... it works perfectly and looks great.
Ty for all the guides/ instructions.
My only question is about the clockworkmod. When I turn off my phone and plug it in to charge the recovery screen always appears when off and connected. Is this suppose to happen? Or is there a solution to this?
If there is a solution can some one post a link or provide instructions so it doesn't constantly boot to clockworkmod recovery.
Thanks.

[Q] MT4G Stuck with "su: unknown user root" Message

I have a myTouch 4G for T-Mobile that I previously permrooted through VISONary r14 and got S-off and am currently trying to install Cyanogenmod7 on.
At some point in time and for a reason I no longer remember, I did a hard factory reset on the phone. Since then, the phone has maintained its "S-off" status, but is no longer able to do anything that requires Superuser.
My main question is on how permroot and S-off work. I am under the impression that to achieve S-off, one must have a rooted phone. However, goes the phone need to stay rooted to keep S-off or will S-off remain, even if the phone is unrooted? It seems like right now, my phone is S-off AND unrooted, with no means of getting back to a temp/permroot status.
I have tried both the VISIONary and gfree methods. The VISIONary method leaves me with the message "su: unknown user root" after I supposedly successfully temproot the phone (and the temproot process either lasts a few seconds, or doesn't complete, even after 5-10 minutes have passes). The gfree method does not allow me to adb push the su and Superuser.apk files, making me unable to proceed after retrieving md5#1.
Use of ROM Manager leaves me unable to flash Clockworkmod Recovery nor download the rom through the app.
I'm unsure as to how I should proceed. I've looked through numerous threads, tried many different methods of permrooting, including VISIONary, gfree, and one click roots, all of which, yield the "su: unknown user root" message.
Any help would be greatly appreciated.
I suppose you didn't even try to boot to whatever recovery you had installed? Try it. If you see stock recovery - it means you did hard reset by flashing stock PD15IMG, most likely 2.3.4 - thus you can't run Visionary app for temp-root, it won't work.
Read the thread "Root for S-OFF users". Find it in Development section.
Download PD15IMG from this thread, with only the recovery on it, put it on your SD card per instructions in this thread, turn off your phone, boot with VolDown pressed to HBOOT, answer "Yes" when asked.
That's it, you have Clockworkmod. Boot to OS, remove the file from SD card, reboot to recovery. Do whatever you want from there - root, flash, anything.
You've been reading, which is good.
You failed to read the obvious, and used very outdated info, which is bad.
I know exactly what you are talking about. The same thing happened to me. What you should do is follow the guide that that the other guys told you to go to. However all i want you to do is push the fre3vo files to gain "temproot". This got me permroot and i didnt really have to even downgrade.
Sent from my HTC Glacier using XDA
No need to downgrade or anything of the sort. PD15IMG in the "root for S-OFF" thread contains recovery and engineering bootloader ONLY, nothing else. Once he gets it, he can flash SU on his current build, should he want to.
This might end up sounding dumb, but absolutely cannot find what thread you're referring to. Closest I can find is this:
http://forum.xda-developers.com/showthread.php?t=834225&highlight=root+for+s-off+users
Can you confirm with a link to the thread you're referring to? I went to the MyTouch4G Android Development forum and "searched this forum" with the term "Root for S-OFF users" and couldn't find anything that seemed to match. It certainly seems like I'm missing something apparently basic to everyone else, but you might have to literally point me there, because I've read through a ton of threads and haven't found something that's actually worked.
Thanks for your help.

Help With my Rooting

I am having a mytouch 4g now running stock rom 2.1. The phone came with S-Off. So if i download the 2.3 update, would it turn my phone back to S-on???
Also does the S-Off mean that if i want to root the phone, i would just need to flash the superuser.zip? or what???
Or Where will i continue from in case i want to root the phone. Also my device is "M4G2DE".
THANKS
I would just grab one of the rooted, debloated stock ROMs from the dev section. The answer to your question about retaining S-Off depends on the method used to achieve S-Off. If root.sh was used, then no. If gfree was used you will keep S-Off.
If you have S-Off then, yes, you can just flash superuser or supersu and the binary.
Edit: Here is Stock 2.3.4 rooted and debloated. http://forum.xda-developers.com/showthread.php?t=1438395

Thanks but when i got the phone, it already had S-Off. So i cant tell how it was done. Or can u help me with how i can detect how S-off was done on my device????
I have temprooted it with visionary and also have superuser and terminal emulator installed.
And when i boot into bootloader mode then to recovery, all i see is a phone with with a triangle and an exclamation mark. Does that mean i dont have a recovery???
Thanks

Most likely it means someone rooted with gfree and flashed the froyo PD15IMG.zip before selling it. The triangle with an exclamation mark is the stock recovery.
Use the permanent root option in visionary to get root. If it doesn't work the first time, reboot and try again. Then use the sticky in the dev section to flash cwm in Terminal Emulator. Alternatively, you can use ROM Manager to flash it.
I would like to recommend 4EXT Recovery Touch. It's amazing. There is a free app to install it online, but the paid app is better. Check Google Play.

No. Getting S-On is a lot more complicated than all that. Just use the method I told you. It'll work. I have rooted 3 mytouch 4G's that way. S-Off is the hard part. You have it already. Just use visionary to get perm root, then flash a recovery.
Also, if you're in a browser, the "Thanks" button is in the lower left hand corner of a post.

Root Question

Okay so I just have a few questions about rooting my phone before I do it, since I saw the root here that works for the most recent OTA update.
1) If someone happens with my phone (either bricking it from rooting or something inconsequential) will they not replace my phone due to it being rooted?
2) If they won't replace it due to being rooted (if it wasn't bricking), is there an easy way to unroot the phone?
3) I can't tell from the instructions, but I'm pretty sure some others have said that it might require you to restore factory settings, does this one require that?
4) The thread says that it is now impossible to unlock the bootloader, does this also mean that you can't use a custom ROM? How exactly do you add a ROM?
Sorry for all the questions, I've never rooted an android device before, and I don't have the time or energy to go running around Google/forums trying to find these answers.
Thanks in advance!
EDIT: yes I know i've already asked 2 of these questions, but I'm a stupid poop who needs validation.

first, rooting your voids the warranty, so technically, they (either VZW or Motorola) are not obligated to replace it. that being said, you can always play dumb and say that you accepted some OTA install, and now the phone won't boot up. usually, VZW will try to restore the phone, and if not, they'll replace it - no worries.
2.) I believe there is an unroot method, but I have not explored this. try doing a search on this forum for "unroot razr m"
3.) restore factory settings could unroot - check the threads
4.) you can still install a custom ROM, but you'll need to install Safestrap first. however, the custom ROMs available for SS are out-dated, and I don't think that any devs will be providing any going forward. however, I would not be too discouraged by this, as the phone is very solid stock. so rooting is the key to remove the bloatware to help increase battery life, increase performance, and reduce excess data usage.
hope this helps.
