[Q} Bootloader - EVO 4G Q&A, Help & Troubleshooting

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.

Use unrevoked forever then go to hboot.. phone off power + volume down button till hboot is up. Check on top left to see s-on or s-off. Itlf it says s-off you are good to go and nand unlocked..

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.
RMarkwald: yeah

[Q]S-OFF Hboot 2.18

okay i had a whole bunch of problems with my evo 4g, so i cleaned everything up and restored it back to stock so that i can root and start over again....well in the process i did all the updates required, and i also did the OTA update to 2.3.5 with hboot 2.18, i DID NOT KNOW that we were not supposed to do this until now when i find that i cannot root it..how do i down grade or what do i have to do to root this damn thing now?
Someone show me how to downgrade my 2.3.5 back to froyo using Odin?
Can't downgrade. Only way to semi unlock the bootloader is using HTCdev

Unless your s-off with hboot 2.18 your SOL sorry. When you said you reverted to stock did you switch back to s-on also or just leave s-off?

Its not on the list but its supported since the bootloader says locked they just haven't updated it yet

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

The 6.16 hboot is the one revolutionary sets it to. No it doesn't make any difference. And there's no need to put it back youre all good

Yea there's a whole bunch of different hboot versions. I don't know of any reason to change it, the end user doesn't use it for anything.
Keep it, change it. What ever...lol

It can and has been done, but it's kind of messy. You would need to download and flash about 4 files to get that to work, and flashing Hboots is always dangerous, especially if you are not experienced at it. There are also several commands that you can run from that Revolutionary Hboot, like re-flashing the Recovery, in case your phone soft bricks that you cannot run with that 2.15 (or 2.16) Hboot.
