I'm pretty sure it is but personally I wouldn't try it.

If I remember correctly you can't. You need to be fully rooted meaning s-off. Basically s-off means radio sercurity off,among other things turned off. If you try to flash anything through clocklworkmod recovery without s-off,either nothing will happen or your phone will be bricked an you will have to buy a complete new phone. Best thing to do is fully root(s-off). If you need help rooting your phone,send me a pm,an ill help you out.

You're right that you must be rooted to flash in recovery, but you do not flash radios in recovery. They are flashed in the bootloader, and I'm not sure root access is required to flash a PD15IMG.zip file in the bootloader. I'm leaning towards root not being required, but I don't know for sure. Might as well go ahead and try it. The worst that could happen is you get the "access denied" message and the installation aborts.

I was thinking that about the radio, I just flashed my first one. After having my phone rooted for 6months. Only reason why I said root the phone. Is to make sure he has full control over the phone. An it takes some risks out,some but not all.

Yea, I was about to say you don't use cwm to flash a new radio but you got it. : P lol

Radios can be flashed in bootloader - otherwise stock firmware updates wouldn't be able to upgrade radios - but they most probably need to be signed to be flashed by S-ON bootloader. In that case, the answer to the OP would be "no".

Unrooting from.....

I just traded some one an HD7 for this MyTouch 4G.... Yayyy, back to Android ! Well, they already have it rooted and everything, but I like to start from scratch when I am modding my phones. I am coming from a Cliq so I'm not familiar with HTC. How should I go about unrooting the phone? And where should I start in the forum while trying to get familiar with modding this phone?
If it's already rooted, why unroot it? I would just make sure the latest recovery is installed, wipe it, and flash whatever ROM you want.
I'd you are looking to mod it... then you want to keep it rooted.
Its a good thing. You can even run the stock rom and make backups of all your apps and settings.
Root is good!

Correct. I would like to start from root and unroot it and know what the whole entire process is for this phone.

Look in the development section... there are many threads with step by step instructions. Search is your friend.

search PD15IMG. Sets you back to stock and unroot.

+1....As Rockstarar said, the pd15img makes you go back to being unrooted. The pd15img is the stock OS image and the thread will on that will explain how to flash it.
After that I'd say check out the "Guide to permaroot" thread, that will explain the process in getting rooted permanently. Next you should check out the thread for clockworkmod Recovery 3.0.0.6, thats a version that enables us to flash both 2.2 and 2.3 base roms. Alot of ppl miss that thread and end up using the wrong recovery to flash roms and as a result they get boot loops.
After that you're good to go! Got alot of options in the development section to choose from, so pick ur poison
I remember when I jus started this thing I had no clue where to start so that should give you a nice guideline on how to get going
Thanks!! I can't wait to get started =P.
Good luck!

(Q) I want to root my mom's phone...

I am very experienced in rooting Samsung phones. I would like to root my mom's phone, which, right now is on bone stock, without erasing any data. I need some help (I also want to keep her on stock, the only reason for this is to install RTL languages on her phone).

Okay, and if I flash the eng hboot, can I just flash a stock RUU to get back to stock and S-On for warrenty?
EDIT: If anyone here is familiar with Odin, what is a similar program to unbrick this phone?

Wait, you bricked this phone? But how? And yeah, you could have done a "permanent root" then RUU'd back to stock/S-ON

About the only way your going to brick this phone is if you flash a corrupt radio or something not intended for the Shift. In a worst case scenario the phone can almost always be recovered by using the the RUU or the One zip back to stock.
Thank you.

No. With temp root changes will be reverted after a reboot.

You have to have the engineering boot loader in order for any /system changes to stick (including the su binary necessary for root access)

You can't flash a PD15IMG.zip RUU in recovery. It's only flashable in the bootloader.

Either way, neither of you have answered the question, so I don't care. You could've kept that comment to yourself and so could he cause he obviously doesn't know a thing about what I'm talking about.
To others who view this, please don't post unless you know the answer. Thanks.

It wasn't a random "comment". XDA is a database like all forums, so even if you already knew the answer yourself, it's important to correct misinformation for anyone who may come across this thread in the future.
Not cool of you to get mad at him when he's just trying to help you.
That kind of an attitude will just deter people away from even wanting to help you out.
Just sayin'.
To answer your OP, why not use the Froyo PD15IMG.zip? Are you trying to unroot your phone?
Using the GB PD15IMG.zip probably wouldn't be the best idea even if it worked. Because if it worked then you're stuck at GB which can't be rooted ATM.

I want the update though. And last time I did the froyo zip while perm rooted with gfree and stock hboot, it bricked the phone. I'm trying to collect all the info first cause apparently I want supposed to do that unless I have eng hboot.

Then why not just flash the update? There's like 3 flashable versions out there in the developmental section.
I flashed it last night, not that great. Don't know how you could choose that over Virtual Unity's Sense 3.0, but I guess to each their own.

I have the 'bad' chip and I'm trying to lose root just in case something happens, I also want the update cause froyo was glitchy and I'm starting to have tiny but irritating issues with unity, like wifi calling and my home screen disappearing.

[Q] returning to stock, is pd15img enough?

hello guys, i searched around on the procedure needed to be done to return a phone to stock for warranty exchange. I read the ultimate s-on guide sticky, but its quoted that if you used the visionary method, that the pd15img flashing may not be enough. thats about all is said on the subject though. if anyone could help me out i would greatly appreciate it. Thanks!!

if you used the visionary root.sh method, then you got nothing to worry about. just flash stock PD15IMG.zip. when reboot, it should show S-On.
ok thank you so much for you help!!
So if I flashed a stock rom via a pd15img.zip that wasn't rooted and includes an hboot, would it still be carrier unlocked ? I have one that I use on at&t and I don't want to lose the unlock and start all over from scratch.

I don't think so. I believe once carrier unlock is there, it's there forever, no matter what you do. Don't quote me on this, as I could be wrong and you could lose the unlock!

If you used gfree to sim unlock it then flashing PD15IMG.zip will leave sim unlock and S-OFF.

[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?

Visionary only roots the ROM. If you're still S-Off you have the ability to write to the partitions through adb or recovery.

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.
