The only way is to root with revolutionary and then flash a 2.2 rom.

You have to be s-off to even attempt a downgrade, First things first. Second, you will probably brick your phone. Do as previous post suggests if u need to that bad.

What are you using to root, Unrevoked?
Is it possible to update your hboot without being rooted? I'd think not but I don't really know.

I don't think so due to S-ON.
HBOOT may have been updated when the official 2.2 Froyo came out via the OTA, but since I was running 2.2 before that and updated HBOOT also, I am not 100% sure with that.

Swapping Evos

Ok I have a rooted EVO with the 2.10 hboot. I'm considering trading with my friend who has an EVO with the for now, unrootable 2.16 hboot.....If we were to swap phones, SD cards, numbers, the whole nine.... Would my phone lose root?? Thx in advance!

since your swapping for the unrooted Evo with hboot 2.16, then yes....you will lose root. hboot 2.16 is still locked and there is no way to root it as of yet. be patient tho....there will be a rooting method out soon...you just have to give it time

No it won't unless you accept an ota etc or unroot it yourself.

correct...that will keep root...as long as your friend doesnt update with OTA
If youre on an AOSP ROM flash a Sense ROM to provision the phone (don't know about about all AOSP ROMs by Cyanogen wont let you put in ## codes or update profile to program), and flash back to whatever you want afterwards. Just don't accept the update.

[Q} Bootloader

What is the stock bootloader version for non rooted Evos? I need to take mine in and I got S-On but it won't let me flash the PC36img and it is stuck in a bootloop now.
2.15 I believe
And I believe s off is needed if you wish to flash.

It is fine to take in with 2.10 Hboot as long as you are running Froyo - just use an RUU PC36IMG file with 2.10 Hboot and you will be fine.

Help please

Sounds like you need to root you phone first. I would use revolutionary to do so. Its easy and quick did it last week when i got my sprint replacement phone.

Wait what ??? My phone is rooted I'm using the express ROM ...
I been rooted for like 2 years now I just didn't notice that I neeeded S-off to flash hboots or radios. Which is weird because I used to flash radios and flash a new hboot with S-on . But now i can't update the bootanimation the PC36IMG.zip file or update the hboot.

This is no problem. I assume you changed your HBOOT to use the Anthrax kernel? Well, you should've downgraded your radio first, and then this would've been a LOT easier. But, since you're stuck at S-ON, now, you'll need to follow these instructions to fix it.

Hey captain I'm guessing you want me to do this? ?
It'll be okay . Boot into recovery and nandroid. You'll need it once you're done.
Just download this: PC36IMG_SuperSonic_S_Sprint_WWE_3.70.651.1_Ra dio_2 .15.00.11.19_NV_1.90_release_161482_signed.zip
Rename to PC36IMG.zip and put it on the root of your SD Card. Boot into Bootloader, and let it update your device.
Then, once it boots up, got into settings and enable USB Debugging, and go to unrevoked.com and select unrevoked3 to root & NAND unlock your device.
Then, you can switch your recovery to Amon RA, full wipe, and restore your nandroid.

If I do this can I still be able to flash the express rom and the anthrax kernel. Or I have to flash another hboot and then do this process again?..

To do this what rom can I use? ??

You won't have to do anything with your HBOOT anymore after this. This will get you back to S-OFF, and at the end, you'll just restore whatever you're running now (unless you just want to flash something else).
You can flash the Express ROM, the Anthrax kernel, the updated radios, and you'll still be S-OFF.
Trust me, just follow the instructions. it's easy. You have to download and install the Froyo ROM so you can re-root with unrevoked. After that, you're just installing a custom recovery and restoring your nandroid.
Okay I got it but you lost me in the last part. Okay so I need to install a froyo rom right now then update the PC36IMG.zip and then let it boot. Go to settings and use the USB debugging and go to the website install the exe. Root the phone and nandroid it? .....

Unrevoked3 didnt work for me. wasted 6 hours

I used captain throwbacks method and down graded my hboot now im at the unrevoked process, I downloaded unrevoked3 ran it and it looked like everything was going great but when it rebooted my phone the unrevoked3 program gave me error message "communications with phone unexpectedly interrupted. Try again." Can somebody please tell me what I did wrong?

rowity and
I'm currently using hboot 2.10.0001 with radio 2.15.00.11.19, I was using hboot hboot 2.18.0001 I read that I could downgrade my hboot to 2.10.0001 that way I can use unrevoked3 to root the phone. I followed all the instructions and used the boot unlocker from htcdev.com to unlock the bootloader and use captain throwbacks method. When I installed the pc36img.img from captain throwbacks guide it seemed to mess everything up. I don't have a custom recovery but I should have one at this point right? I am so confused. I have s-off but it says I don't have root. I did have HTC sync installed when I tried to root it the first time and it failed so I had to uninstall HTC sync.
I can't remember but shouldn't it be "PC36IMG.zip"..? Been a while since I rooted my phone.

Your radio is too new for unrevoked u need to bump your hboot up to 2.16 and use revolutionary.io I don't know any way to downgrade the radio with s-on so u can use unrevoked
