[Q] Question about Mytouch 4g that lost root - myTouch 4G Q&A, Help & Troubleshooting

A month ago I rooted my Mytouch 4g and flashed Toasted Marshmellow with no problems. I wanted to go to Synthetic Nightmare's ICS rom since JB seemed a little too glitchy and used ROM Manager to do the flashing for me. However,when my phone booted back up, the white H-boot screen popped up instead of CWM. Instead of pulling the battery out, I accepted the update which brought my phone back to stock froyo. I still have s-off and my phone is no longer rooted. I tried to permroot and flashanother rom again today only for my phone to be stuck ont the Mytouch 4g screen.
I don't know if I should go back to s-on and try the process of s-off and permroot again?
Thoughts!

Have you tried pushing recovery back to your phone with adb? Or if u r stuck on the white logo screen u will have to use adb to communicate with your phone, to regain root? Someone? Possibly if u tried to reflash a rom then your boot.img may be different than the rom since you weren't rooted? I don't know, I'm just thinking out loud..brainstorming

Ok, push the pd15img.zip into bootloader and reset back to stock if you haven't already done so. Then do the gfree rooting method to gain Perma root.

I'm able to push the pd15.img with no problems and was able to successfully root through visionary, but now it seems I can't flash any roms. I've tried numerous times only to get either stuck at the mytouch 4g screen and once it got an error and the installations was aborted. Everytime this happens, I have to repush pd15.img and re-root. It's been going on since yesterday and am so frustrated to the point I'm ready to give up.
I love having custom roms, but this is stupid!

Also, try using 4ext recovery instead of CWM. Maybe you will not get an error. Wipe data, cache & dalvik, the format everything except sdcard. Then install zip from sd (rom of your choice)

Yup that's why I recommend it its the best. Also take any pd15img.zip files on the root of your SD card and either move it into another folder or delete it completely to avoid any similar problems from happening.

Any error in installing a rom I have ever heard of, 99% of the time has been from cwm recovery. I've used both, but I'd never use anything but 4ext now. Glad you're up & going again...

Permaroot Issue

Hello everyone,
I've followed the directions for the s-off and permaroot to the "T". I have s-off in stock recovery, but when I reboot I don't get superuser permissions automatically in terminal, or any other root app.
I temp rooted again with visionary 14, went back into terminal and sync. Waited again for 2 minutes, rebooted and still, no root at boot. Any suggestions?
P.S. sorry if this is a repost, I've searched for this in many threads, but no luck. Disregard with a link if so. Thank you in advanced.
If you have s off then use visionary to attempt perm root. That's what I did and I now have s off and root permissions.

He's hitting the buttons right, it's just that he's got the stock recovery installed.
Flash clockworkmod again, then try rebooting into recovery mode using rom manager.
Sent from my T-Mobile G2 running Cyanogenmod.
If you're still getting red triangle after flashing cwr, check the option "erase stock recovery" or something like that in settings. That worked for me.
Yeah that's what I did. I checked it, reflashed clockwork, fixed permissions and problem solved. Now the big cm6.1 or baconbits decision..
Thanks for all the help guys

Ruined my boss's HTC MyTouch 4G

I have an Epic myself and the security of this new HTC phone threw me for a loop. Anyway , I was trying to put CM7 on his phone , starting from stock. I managed to get CWM 3.0.0.5 on it and then flashed the CM7 from here. Now it is stuck on the white Tmobile screen , Ive let it sit therefor an hour and nothing. But the real problem is that I cant find a way to restore to stock and start over. With the Epic we use a windows program called ODIN in case something like this happens. Ive tried using ADB but the phone is showing offline so I cant push any commands to it. Is there an app like ODIN that will let me factory reset this phone and try this again? Thanks
Sent from my SPH-D700 using Tapatalk
Sounds like you rooted and flashed CM7 onto it without having s-off. If I'm not mistaking there is another thread similar to this one somewhere. Also you need cclockwork 3.0.0.6 to flash back and fourth from stock and other roms.
you need pd15img.zip on your SD
pd15img.zip reboot into hboot with that file and the part7-0000000000.bin file on your sd and it will load and ask you to push volume up to confirm then wait, it will restore the phone i know i did it, took me 3 damn days to figure out you need that part7.bin file on your sd with that pd15img.zip file...or its a no go, trust me this WILL def work...its a life saver, i did the same thing you did...had clockwork and no s=off...now i successfully restored it and sent it back to tmobile because before i solved it i panic and called for a replacement, told em it wont turn on, they sent the new one, and about 20 mins ago i flashed cm7 after folling this guide http://forum.xda-developers.com/showthread.php?t=858996 to turn s=off...works great good luck
Where do i get the part7 file and the other one? Thank you

It was creates with you permanent rooted it.. should be on your SD card. In the rooting instructions it tells you to keep that file around.
Sent from my HTC Glacier using XDA App
Just make sure that u dnt keep tryin to flash the rom cause u gonna end up gettin the cant mount cache & data errors,which once that happens nothin can b done with the mt4g.. So if u used the gfree method to root the phone u should have the part7-xxxxxxxx.bin file,stick that to the root of the sd card & put the pd15 file to the root of the sd card,powerdwn or battery pull,reboot into recovery & let the phne do its thing..
I don't think he has that part7-xx......bin file for his mt4g phone since he did not run gfree patch. You can't do stock nandroid restore also because that requires CWM 2.5.1.4 but you can always give it a shot.
Good luck with your boss, hope you don't get fired.

I didn't use the gfree method for getting perm root.
So i never got that part7 file that you speak of....
I have found them online to download but even using someone elses i still doesnt load the .zip from hboot :{
I downloaded the glacier file , like 350 MB or something , renamed it to PD15IMG.ZIP (had to leave the .zip out because windows). Then I found the part7.bin file from another thread. Put both on sd card. Vol down and power, it found the pd15img file and started restoring the image. 15 minutes later the phone boots up just like brand new! Thank you to everybody who helped with this! Sometimes I dont know what i'd do without this place!
P.s.- he still wants gingerbread any suggestions as to best rom?
Thanks again everyone

I think you made a fine choice with CM7. Just make sure you are rooted and have flashed the latest clockworkmod through ROM manager (3.0.2.4 I believe) and it should flash without issue.

Bought Evo on eBay... has s-off but recovery goes to red triangle

Ok bought an evo on eBay, after getting rid of my evo for a blackberry and realizing I made a huge mistake. It's used but like new.
I go to the boot screen and it says s-off. Then I select recovery but it goes to an evo with a red triangle.
What can I do?
Thanks

If you can acess the bootloader, I would recommend searching in the rooting wiki and look for a PCIMG file place that in the root of the sd card(hopefully your comp has a media reader) and insert the sd card with that file and the bootloader should detect when you select recovery.
What that file does is resets everything on the phone to stock. if you could find a RUU that might work but if your comp cant see the phone its useless i hope this helps

If you're s off, your rooted. The triangle means you have no recovery. All you need to do is flash a PC36IMG of recovery, using the bootloader. Once you do that, you'll have recovery, and can flash a rom of your choice. That's it. No need to re root or ruu or anything like that. Just recovery, that's it.

This would probably be the easiest thing. DL clockwork from the market and install the recovery I prefer amon_ra it will be at the bottom under alternate recoveries. Also do a nand backup as soon as you have a recovery.
I agree with above, just get rom manager from the market and flash a recovery...simple
We're comin from a pure power source.

SUre, give me one sec to upload a file for you. And as the other guys suggested, flashing a recovery using ROM manager would be your easiest bet. HOWEVER, if you dont have the SUPER USER app, (which i bet you do not), rom manager wont work. t herefore you cant flash anything with it.
So give me one sec, and i'll upload what you need to flash, with instructions for ya
EDIT: I attatched a recovery for you. It's Amon Ra V2.3. Download the PC36IMG, and leave it named exactly as it is. Place the file on the main directory (root) of your sd card. Power your phone off completely. Then boot to the bootloader by holding the power and volume down buttons simultaneously. When it gets to the bootloader, after a sec it will scan for files, and find the PC36IMG. It will then ask you if you want to update, so select yes (volume UP). Once it's done flashing, it'll ask you to reboot. Select no. Then choose the 'recovery' option from the bootloader menu. You should now successfully boot into Amon Ra V2.3 recovery. From that point, you can create a backup of your current setup. Then you can perform a full wipe, and then flash the rom of your choice.
And what ever you do DON'T restore a nandroid from your old phone. You will wipe out your 4g if the wimax partition is included in the nandroid.

Ok that worked. I now have Amon ra recovery
But, lol, one more question. Amon ra has changed since I've had an evo.. now when I select backup, it has a list of things I want to back up with "[x]" next to them. Which items should I select? It didn't have that feature in the past so I'm a little lost.

Right, that feature was added after version 1.8.0 (which I still use). I believe you want to check all of the boxes, for your first backup. (I'm not sure if you need to have everything checked after that, but I'm sure it couldn't hurt). I've seen people say that you only need to back up your wimax one time, then keep the file in a safe place (it's your RSA keys), however I just can't see what the problem is with backing it up each time. I kind of like the simplicity of 1.8.0, just hit backup and let it do it's thing. Whatever the heck 1.8.0 automatically backs up on its own, works perfectly fine for me, lol.
So I would just check everything off, and then let it perform the backup.
EDIT: and sorry I don't have more info on that for ya. I'm sure someone else who regulrarly uses ar 2.3 will chime in, and give you a more solid answer. I just simply don't use that recovery, as I never saw a need to 'upgrade' from 1.8.0, because it has always worked flawlessly for me. If it ain't broke, don't fix it. I'd say you could use 1.8.0 if you wanted to, but I believe it won't work on the 004 hardware phones with the 0040000 size erase block.
Ok cool.
Thanks again
And yes i remember the simple way, things are supposed to get easier as time goes on, not more complicated, haha!

Perm Root not working

I followed multiple steps for installing perm root on a friends Mytouch and for some reason we could not get the s-off feature to work. I noticed too we do have SU access via adb or terminal but I still never could get s-off. After we got root we used rom manager to install clockwork and after the fact it installed 3.0.2 i believe it completely borked the recovery. I stepped it down to 3.0.0 and still had the same issue. The main reason i wanted to get s-off was to adb flash the recovery but I got a signature fail. Any ideas or suggestions to get this working correctly? Rom Manager will not let me install 2x cwm basically stating it can not install it period. I also tried the batch file root method same issue. Thanks for your help in advance.
Please look at the "True permaroot and S-OFF" thread in Development section, and execute step-by-step.
If your friend's MT4G is running Gingerbread (Android 2.3.3), you'll need to use Gingerbreak instead of Visionary+ to get root access.
Its on froyo and i followed that guide i have perm root but we can not get s off. I can use root access for any programs

If you are following the ./gfree method step by step it will root your phone.
If you are using the root.sh script and it's not working chances are you may have a bad eMMC chipset and it will not root properly.
I know HTC said they would be pushing a update to close the exploit hole that is used to root our phones but i don't think it's been pushed yet.
Im not sure but it said something about not being able to back up partition or something but either way nice HTC is becoming a motorola nice

HTC isn't "becoming a Motorola". HTC, is completely different. We do have a locked bootloader. But it's easily unlock-able whereas Moto's aren't.

I don't know what to tell you. There are several threads out there regarding how to root your phone. Both in a .gfree form and a root.sh form. One of those 2 work for 99.9% of EVERYONE.
You might try finding someone who put together a .zip that can be flashed through the android recovery(white screen with boot options, etc.). Otherwise you can get the RUU and return to stock. After that follow the directions step by step and DO NOT mix methods. This should result in an S-OFF root, if you did your homework correctly.

As someone already explained before, when the security is on, no matter the amount of flashing you're going to try - it won't get you anywhere, since it won't be written to the actual ROM, and will be gone on restart.
Unless you pick a guide, follow it exactly, and post here everything that doesn't look proper - I don't think the forum can help you much.
Here's one:

Sent from my SGH-T959V using XDA App
What does your bootloader show when you boot into it?
For the root to stick after boot, you had to have S-OFF, otherwise the eMMC wouldn't have been written to.
Having no info from you, as I said, it's impossible to help. If all this thread is just a complaint - by all means, but in that case there's no point in helping you. If you want help - you need to provide enough details for people to help you. Obviously, nobody can figure out anything from "I can't get s-off".
I do a adb reboot bootloader and i get us fast boot up top it says s-on but if i reboot to the os i still have root access for instance in titanium backup or Rom manager of that helps any

[Q] Bootloader?

Hey Guys,
So im in a bit of a peculiar situation here, I downgraded my device from Gingerbread to 2.2.1 following the wiki (kudos to whoever did that, thanks a lot!). However, when I got to 2.2.1, it now only mounts my SD card as read only? I have ordered another one to see whether i just got a crappy sd card (Tmo refused to replace it under warranty)... However, I have pushed Visionary and Gfree, in preparation to root this sucker, and have my way with it...but heres the caveat, is that now, when I try to boot into recovery, I get that stinking little phone with a red triangle on it...what does this mean?
Regards
Trevor
That means you don't have a custom recovery installed
Download Rom manager from the market and install the clockworkmod recovery
Edit: until you root the phone my post is useless the custom recovery is for after you root the phone
If you need help rooting the phone mackster248 has a great 2 part video showing you how to root the MT4G on YouTube

right, so if i am still able to root my thing using gfree then flash custom recovery? So...im not hosed yet?

PS, is there an way to reformat an sd card through ADB, i think it may be read only because of some corrupt sectors, and would like to try to reformat it...does the fdisk utility do this?
