[Q] Bootloader? - myTouch 4G Q&A, Help & Troubleshooting

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?
trev

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?

[Q] Bricked HTC Mytouch 4G?

First off let me start by saying I now know what i did wrong. Next is there anyway i can fix it?
I didn't backup anything and then managed to erase everything... I have CM 6 but as of now all i can get is the boot screen. I tried recovery but that won't work becasue there is no backup. also Before I erased everything i managed to turn s on so now i have no way to turn that off correct? Im basicly looking for a way to restore my phone but if it cant be done then i understand. Right now I am using a samsung vibrant with Nero v3 voodo and understand how to install custom roms now
i have almost the same problem as you I don't know what to do I've looked everywhere.

What do you mean... erase everything? How?
Possible steps:
1. factory reset from H-Boot, see if it boots up normally, then re-root.
2. Install PD15IMG from development section, look it up.
Good luck.
Man, do I feel like an idiot...

Which recovery did you have installed and which h-boot
Did you try seeing if you could s-off through adb? Im not sure if this will work but Download the files you need to get s-off from ur computer and put it on ur SD card via a card reader or some sort, after you get the necessary files put the SD card back into ur phone. Hook it up to ur computer and maybe you can s-off through adb if you can get ur computer to recognize ur phone. Then IF it works, download a rom via computer to it SD card and boot into recovery and flash. Let me know what happens if it works or not

Should have taken my advice from this thread.
I just went thru the same thing and couldn't restore any of the backups it just kept getting stuck on the flash screen. I downloaded the ice glacier rom on to a spare sd card and flashed it thru hboot recovery and it looks like that did the trick.
hi guys if you still cant get your phones working try mobiletechvideos.com, they fixed my phone , my phone wouldn`t do anything .good reliable service, yes its in texas.
Although you didnt create any backups, is it possible that someone can create a backup of a fresh ROM and send that to you?
youshoe said:
Just take the SD card and put a new ROM on it. Then go to recovery, wipe data, wipe cache, wipe dalkik cache.
Then install zip from sd card and find it.
I like using Royal Panache 1.3.
I think it's stock Mobilicity ROM but no stock software from carrier. Good stuff.
MIUI and Cyanogenmod 7.1 are also good candidates.
I'm currently testing out ICS and you can test it out as well (but in your case, probably try a working one first =P) http://forum.xda-developers.com/showthread.php?t=1383629&page=1

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.

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:
http://forum.xda-developers.com/showthread.php?t=858996
Follow it and post anything that doesn't look good. Including your bootloader version.
The root is sticking on reboots but still no soff that's what i have been saying and i followed the guides to a t its not my first picnic rooting or roming a phone this one just has me stumped
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

Problem rooting mt4g 2.2.1

So I've rooted my phone twice following the instructions on theunlockr.com without any problems. Tonight I tried rooting my dads phone and I got temp root using visionary and then was able to get S OFF but now once I rebooted and tried temp rooting it again I can't get it to work. Most of the apps just force close as well. The only thing I can think of is to factory restore by flashing the PD15IMG and then starting completely over. Anyone know why this is happening and what to do?

Try ./gfree. Never fails. This is happening because your dad probably has the bad emmc chip

People tend to assume stuff without even thinking.
What happened to you, happened because of data corruption. Doesn't say anything about "good" or "bad" eMMC, definitely doesn't suggest that your phone is dead and needs replacement. But this thread suggests that reading, searching and thinking will get you better results than listening to people.
You already got S-OFF.
Most probably the only thing you need to do now is to get into bootloader, factory reset the phone, boot into the OS fresh (which will almost surely eliminate all the FCs you're seeing), install Visionary again, temp-root, and install custom recovery.
If you rooted with root.sh method (means, you have engineering bootloader installed) - you don't need even that. Get your fastboot operational, boot into bootloader, go to "fastboot" menu, connect the phone, download any CWM recovery image from the net, and "fastboot flash recovery your_downloaded_recovery_image.img".
And you might get it even simpler than both of the methods above:
Look in the Development forum for instructions on gaining root when already S-OFF. It's as simple as flashing PD15IMG with only a custom recovery image inside it. Since you're S-OFF, the image will be flashed by the bootloader without questions, and you'll get a custom recovery. The PD15IMG will be found in the right thread.
From there just boot into recovery and install a custom ROM of your choice.
Good luck.
Search before asking next time.

[Q] Question about Mytouch 4g that lost root

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

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...
