[Q] Possible to flash CMW after OTA GB update? - myTouch 4G Q&A, Help & Troubleshooting

Is it possible to flash Clockwork Mod Recovery after applying the 2.3.4 update?

Yes if you have s-off

How about for us people with s-off and stock 2.3.4? Are we stuck on this ROM until someone gets root?

no if you have s-off you can flash Clockwork Mod Recovery or you can downgrade

I believe that they are working on a way to break 2.3.4 still. I haven't noticed any post confirming a successful root of the OTA update.
There has been some talk about gingerbreak doing something but it was experimental and I didn't do a whole lot of digging so I wouldn't recommend even trying.

Follow the instructions on this thread and you should be able to downgrade then root.

Does anyone know if there's an updated guide to downgrading? I think the links (like to download the JAVA JDK) needs to be updated. I've spent hours reading and trying to find exactly what I need to download. I've tried installing 3 different JDK and none of them will let me install the Android SDK.
Edit: I found a fix to my problem. The Android SDK wasn't detecting JDK, all I had to do was click back then next, WTF...

Find the above file, have it saved to root of sdcard, boot into bootloader, bootloader will find the file on the card and prompt to install the stock image... follow prompts and done.
Nandroid first but really is easy.

I first flashed the 2.2.1 OTA. Then I flashed the stock recovery. Afterwards, flashed the stock radio. That's what I did. All are available in the Development section.

You could have used pd15img.zip to do all of that in one flash via hboot.
It's safer to flash back to the stock radio first to avoid getting stuck in a limbo situation in which attempting to flash back to stock results in "Main version older" with radio s-on rather than do it all in one step.

This guide should solve your problem. It involves hex editing the misc.img among other things to allow you to successfully flash back to stock.

If you used the gfree method of rooting, the following guide is pretty good:

Rooting 2.3.4

No root for the OTA yet, but downloading to 2.2.1 and rooting that will net you the same result as rooting the update. Are you just worried about downgrading? I think i have seen you ask this before.
I just got a device with the ota. I just don't know how to do it there's no guides.

I also can confirm that the downgrade works. Just make sure you download the usb drivers for the MT4G and read about ADB it's very easy if you follow the instructions.
I was concerned about bricking my phone also but it does work.
Good Luck.

[Q] rooting mytouch4g 2.3.4 gingerbread

is there any way to root mytouch 4g 2.3.4
would i have to downgrade to 2.2.1?
yes, downgrade to 2.2.1, root, flash the rom of your choice
you have to downgrade at the moment.If you to to the development section for our phone, then look for resource Bible. In the guide section, there's 2 threads on how to downgrade your phone to 2.2.1 . Once that is done you can either root with gfree or root.sh.
From my fist to your face, enjoy.
You can do the above mentioned.. or just wait. There are ppl working on a straight method.

If you have s=off already all you need to do is flash a recovery image, then backup/wipe/flash the ROM of your choice.

You must downgrade to 2.2.1 before attaining S-Off.
No one here recommends HTC Dev.

ok thank you
I incorrectly assumed you had S-On.
Do you have a custom recovery? If so, there is a rooted 2.3.4 in the dev section you can flash.

You bet. As long as it's for the myTouch 4G.
On our phone, S-Off is the most important thing. Flash away. Just make sure you wipe data, cache, dalvik and system at minimum. I would recommend you look into 4EXT recovery if you don't have it.

[Q] Lost Root.. can't regain... HELP

Ok, so my wife's phone has to go back to TMOBILE by Friday Sept 21st, I have Virtuous Affinity on it and I Unrooted with VISIONary not thinking that i should have flashed something stock first. I now cannot regain root for some reason using VISIONary or even flashing a PD15IMG through bootloader,,, I'm not comfortable at all with ADB, please help if there is another way. Anyone?

Is your phone still s-off?
Sent from my Toasted Marshmallow using Tapatalk 2
Visionary only roots the ROM. If you're still S-Off you have the ability to write to the partitions through adb or recovery.
Tell us what happens when you try to flash PD15IMG.zip

Still s-off... Flashing the P15IMG shows the progress bar on the right, then either reboots in its own or I reboot it... Still goes back to custom Rom.

I downloaded multiple versions including the 2.2.1, 2.3.4, and 2.34 (new) version... all those did similiar things, still not getting me back to stock. Does it make a difference that I have a custom rom with 2.3.5 on it?
Any other thoughts?

Why would it make a difference? Also, if it did, I would have asked you about it.
The only reason a good download will not install, usually, is if either you're on an unlocked bootloader from htc-dev, or something is wrong with either your bootloader or phone.
