CM7 installation question

---

Hey everyone! I have a question that I couldn't find the answer to in the General or Dev forums.

My brother asked me if I could root his phone. I have experience with rooting, CWM, etc on my phone (Atrix), so I told him that I could, but I'd have to do some research first.

He did install the 2.3.3 update, so I understand permanent root is not possible yet. So here's my question-
Is there anything that would stop me from executing the following sequence and successfully getting CM7 onto the phone?

Gain Temp root
Rename install_recovery.sh to something else
Install ROM manager
Install CWM Recovery
Have ROM manager download CM7
Flash CM7
Done


Thank you in advance!

Will not work, the bootloader is locked so flashing roms isn't gonna happen.

I dont think that would work... The shift is as locked down as the atrix was. I am pretty sure the partitions would still be write protected with only temp root...

I didn't even think about the bootloader possibly being locked. I always thought HTC had unlocked bootloaders until very recently (Evo 3D) when they released locked bootloaders, then announced that they would allow you to unlock them.

According to this page:
http://wiki.cyanogenmod.com/wiki/HTC...ineering_HBoot

Flashing that will unlock the boot loader. So I should be able to change my steps to:
[Edit: That site is basically instructions on how to install CM7 onto the Shift, and those steps only require temporary root to execute.]

Gain Temp root
Flash HBoot
Rename install_recovery.sh to something else
Install ROM manager
Install CWM Recovery
Have ROM manager download CM7
Flash CM7
Done

Is there anything else that would stop my process above from working?

EDIT - MY Atrix had a new bootloader installed when I did the OTA to Gingerbread several months ago. If the Evo Shift also got a new bootloader with their GB update, three is a chance that flashing HBoot could brick the phone. I'm going to start looking into this now, however if someone knows the answer to this I'd appreciate an answer

Wont work... We have an emmc partitioned phone just like the evo 3d. The o.t.a. to 2.3.3 included a new locked/encrypted bootloader. The partitions are write protected and encrypted. Flashing the eng hboot with a locked/encrypted recovery partition could equal brick...

Thanks for that info, I couldn't find confirmation either way on the bootloader. I was going to check check MD5Sums before flashing the HBoot just in case.

So can I restore back to Froyo and the old bootloader? On the Atrix you could do this (as long as you didn't unlock your bootloader) by using RSD Lite and flashing the stock SBF file. A quick search on the Evo Shift implies that I can do something similar with the Evo Shift - RUU back to stock Froyo? I admit I know nothing about how that works, I'll start searching now, and any additional info would be great!

Edit: Looks like there is no way to do that either, there doesn't seem to be a way to go back. Interesting that the phone got a new bootloader with the OTA update. My Atrix got a new bootloader with its 2.3 update too, but that was because the new bootloader allowed the users to unlock it. I also see that HTC's online unlocker doesn't list the Evo Shift. So it looks like my brother installing the OTA screwed himself out of getting to run any custom ROMs.

You got it man... Sorry to be the bearer of bad news... Htc went all moto on us... They even used the same style of 256 bit encryption... Effing ****ty!
