Root HTC EVO V 4G Boot Loop

Hello! I'm a complete noob to this, but I'd appreciate any help that's noob friendly and stuff, thanks :).
Here's my story. About 3 months ago, I rooted my HTC EVO V 4G Virgin Mobile phone. Everything was fine, I did not get S-OFF, but I got TWRP recovery. Recently, I installed another recovery, something weird 4EXT somethin... and I used that to flash a rom. (I had flashed roms before with TWRP and everything was fine). After flashing, my phone started bootlooping. So I figured it was just the rom, and booted into recovery and flashed my old rom back on. It started boot looping as well. Not really knowing what the problem was, I got on my PC and flashed the TWRP recovery back on my phone, and tried to reflash the rom. It's still bootlooping. Could someone guide me back to fixing this? D:

Thanks so much in advance.

It sounds like you probably flashed an incompatible rom. Without being s-off, you are very limited on choice of roms to flash.

Do you have a card reader? Try browsing your sd card and find your backup and copy/paste the boot.img from that backup into the folder on your PC that has adb/fastboot. (Same place you put the recovery.img when rooting)

Then get into fastboot usb mode and use fastboot command:
fastboot flash boot boot.img


 
Thanks for your reply! This rom, *(midnight rom)* I've previously flashed and was perfectly fine. It's just bootlooping now, after I reflashed the same rom, and I'm not sure why.

Basically being s-on, you can't flash the kernel with the rom except for two exceptions.
I think I know the likely reason it worked for you before. First I will explain the three possible ways for s-on users to flash roms briefly:

1.) (Most difficult way) Enter recovery, flash rom. Take boot.img from rom and flash it through command prompt: fastboot flash boot boot.img
Rom should boot after that. This method is very unnecessary and a waste of time because of method 2.

2.) (Likely the method you used the first time flashing that rom. Probably after rooting)
Temporarily boot the recovery into the phones memory using fastboot boot recovery.img
After booting your recovery that way, you can select the rom and flash it in your recovery. This will allow you to flash the boot.img with the rom thus eliminating the need for the extra step in method 1.

3.) (Simplest method. No PC Required) Use 4ext recovery with "Smart Flash" enabled. This will allow you to just boot into recovery from the phone and flash a rom. The smart flash feature is made for s-on users to flash the boot.img and avoid the extra steps or having to use fastboot commands.

I'm guessing you flashed that rom after rooting and used the fastboot boot recovery.img method and didn't realize that it makes a difference. Second time I'm guessing you just got into your recovery and flashed. Try using fastboot boot recovery.img then once in recovery wipe all and restore your backup to get booted back up again.

P.S. Get s-off.. Will save you so many flashing headaches. You don't have to jump through hoops anymore once s-off :)
 
Thank you so much for explaining! I'm going to try your method right now!! If for some reason that it fails to work, there's still hope right? I'm kind of freaking out right now :(

Okay thanks a bunch! I'll update you once I'm done. I'm afraid of S-OFF because of the thing that involves using a wire and stuff. I was scared enough when rooting haha. Okay be back soon~
 
Oh no!! It's still not working !!! I'm really nervous. There's hope right?
The HTC logo pops up, then the start of the midnight rom boot animation,... then a dark screen. That's it. If I manually power it back on, it boot loops.

PS I did this "2.) (Likely the method you used the first time flashing that rom. Probably after rooting)
Temporarily boot the recovery into the phones memory using fastboot boot recovery.img
After booting your recovery that way, you can select the rom and flash it in your recovery. This will allow you to flash the boot.img with the rom thus eliminating the need for the extra step in method 1."
I wiped all, installed the rom. Rebooting results in what I just described.
 
As long as your hboot works, you're fine. Can you get into recovery? If so you're fine.
I can't help you fix it, but a brian/ramjet tag team can get anyone up and running as long as you can boot to the hboot.

Holding volume - and power is how I normally get to the hboot bootloader. If you can get there...you're fine. No need to panic.:)
 
Oh thanks so much. I was just freaking out. I figured I can get into recovery and fastboot. And that white screen is hboot? Yeah I think so. Thanks I can stop freaking out now. I just don't know why I can't get this rom working D: haha
 
The bootloader is the screen you get to by doing a battery pull, and then holding volume down+power. It displays your hboot version etc...

If you rooted before and never took the March update, as a last resort, you should be able to run the RUU to get out of anything if the situation gets too desperate. If you did take the update, no RUU until you're s-off... Kinda scary, as sometimes you do hit a situation where it's necessary.

Okay, how about a fresh install of the rom?

So you have no problems getting into fastboot usb mode and issuing the fastboot boot recovery.img command right? Do that, and then format all partitions (except sd card) and try to flash the rom again. Remember it's important to enter recovery with that command and not just selecting recovery from your bootloader screen.
 
Hey thanks! I have no clue what RUU is, or the March update. I'm unaware if I've taken the update, how do I check? Also, should I try a different rom? I've already entered recovery through CMD~
 
Nice. That means you didn't take the March ota. So you still have the ruu available. It returns the phone to factory stock. Unroots everything. Sometimes it can fix certain issues.

Ok, that means your phone is fine. Well, it's not bricked at least ;)
You'll be without a phone until you get it fixed, but you don't need a new phone. You just need to follow the Guide's directions exactly, and report back what you see. I capitalized guide because i am referring to a person with the "Guide" title, not a step by step guide. Brian is already in this thread, so pm him if he hasn't replied after awhile.

Edit:
Ok, so I type slowly on my phone while watching tv. Brian has already responded.
 
Moved to Evo V 4G - All Things Root for easier location should this issue be experienced by others in the future.
 
I just did the same thing ERG. And it played the obnoxious boot noise, and shutdown. WHAT IS WRONG????


EDIT: Sorry I just put this in the wrong forum I dunno how to delete.
EDIT: No I didn't nevermind.
 
It appears the same thing is happening each time. The rom starts, shows the start of the boot animation, and powers off. I lied about the boot loop, it only does that if I try to restart the phone. Anyways, I'm able to access that hboot thing, recovery, fastboot, and my phone is unlocked. D; Are there other possible solutions ? All of this weirdness started happening when I flashed a different recovery. It was so I could have this fancy "Smart Flash" thing. Everything just goes downhill from there.

oh just noticed that big red button. is that what ruu is? that big factory reset button O_O

At this point it may be best just to run the Ruu and start over :/ I'm not sure what's going on. Usually in these situations a flash of the boot.img will fix it. Let me get some links and stuff for you. I'm not on the pc now so I'll be a little slower with detailed instructions. You may want to consider s-off as well... It will save you so much headache.

For now go to this guide and download the two files from the preliminary steps:
http://androidforums.com/evo-v-4g-all-things-root/695161-s-off-root-fix-everything-all-in-one.html

The rom update utility (ruu) will take awhile.

After you have those we will continue. But honestly I would follow that guide and do it all including s-off... If you follow its start to finish and don't skip steps you will be golden!
