Default Evo V 4G rebooting after failed ROM flash

I recently installed rooted and flashed my Evo V 4G.

Everything seemed to be working well and I managed to flash the ODEX ROM mentioned in the guide, making a recovery and everything. After I did that, I attempted to flash the CM10.1 Android 4.2.2 ROM for Sprint Evo 3D (to my understanding this should work with the Virgin Mobile version as well?). After flashing, the CyanogenMod logo popped up and a screen stating that it was initialing and updating all the apps came up. Once that finished, however, the phone began to constantly reboot itself without me ever actually getting to use the ROM itself. It simply displays the HTC logo for a bit and then the CyanogenMod logo before rebooting again.

Since I still have access to TWRP (removing the battery, then pushing down the volume button plus the power button), I attempted to load the backup that I had saved prior. However, after a long time (1066 seconds), it loaded only to suffer the same rebooting fate (although it no longer says Cyanogen Mod since the backup was saved with the ODEX ROM). Is there any way I can simply access my phone normally again (I don't care if I have to return it to stock conditions in order to do so). Thanks.

You must be S-OFF and using a different HBOOT than the one you've got to flash that ROM. Also, you either have to have taken the OTA update or have performed the "fix everything" steps.

I'd also recommend flashing 4ext recovery instead of TWRP.

Seems a few people's issues would have been resolved by following my guide today... just sayin :P

Yes, I did wipe everything and made a recovery before originally flashing ODEX (that went without a hitch). I'm on HBOOT 1.57.0000, S-BOOT is on, and I followed this guide:

Complete Newbie's Guide to rooting and flashing Evo V 4G ROMs/Kernels using fastboot

Would you guys hapen to know why I have the same rebooting problem with the ODEX ROM then? I've flashed it once already so I know it's capable of working. Also, I will use 4ext in the future, but is there any way to recover my phone for now?

My recommendation is to pull the battery out of the phone, then replace it.

Hold the volume down button, and press the power button. Your phone will reboot into the HBOOT.

Once in the HBOOT, select bootloader, then recovery. Wipe your phone and restore your backup. If that doesn't work, flash 4ext using fastboot (I will provide the file if you need it -- I haven't uploaded just that file yet, it's in a package).

I think I tried that already but I will do it again. Also, I'm not sure if this is of any importance, but when I enter HBOOT, I see a bunch of lines that say "no image". In addition, can you explain how you would flash 4ext? I'm new to all this stuff as you can probably tell. Thanks again!

Those "no image" lines strike me as odd. Any chance you can take a picture of that screen and upload it to imgur or another image host? OH!! Any chance you have a PG86IMG.zip (or another similarly-named zip file) on the root of your SD card? If so, that has to be deleted.

At this point I'm thinking that running the RUU would be a good option.

To flash 4ext, download this file and place it in the same folder that you will be running fastboot from. After that, run the following command:
[HIGH]fastboot flash recovery recovery.img[/HIGH]

You should be in the bootloader (HBOOT) before running the command.

Also note after flashing 4ext you cannot restore your backup made with TWRP, so you'll be starting from scratch with a ROM.

Should the recovey file be placed in the sdk-tools folder on my desktop? Also, after flashing 4ext, should I just try to flash the ODEX ROM? Thank you so much for all the help.

Yes sir, put it in your sdk-tools folder and it should flash without issue from the bootloader. I would try the ODEX rom first, since that's the one you've got. If it doesn't work, there's a couple other steps that will most likely fix your issue.

Once you have 4ext flashed, you can select "bootloader" from your HBOOT, then recovery.

Once inside 4ext, select wipe | format. The second-to-last option is format all partitions (except sdcard). Tap on this and confirm your selection.

Once that's done, flash the ODEX ROM.

You're in the HBOOT? Sounds like you have a driver problem -- uninstall HTC Sync if it's installed, then install this driver package.

Once you've got that installed (may require a reboot), issue "fastboot devices" when it's in HBOOT, and you should get a return of a serial number.

I tried to flash the 4ext recovery file and got this:

C:\sdk-tools>fastboot flash recovery recovery.img
sending 'recovery' (5132 KB)... OKAY [ 1.540s]
writing 'recovery'... OKAY [ 1.883s]
finished. total time: 3.424s

However, once I select recovery, I still see the TWRP recovery. Did I not flash it correctly?

Seems like the recovery image you flashed wasn't 4ext. Delete the one in that folder and replace it with the one linked above. There may be a slight difference in size because I'm on Linux, but for me it's a 6914 KB file.

Oh wow yeah I had an extra folder similarly named no my desktop and put the new recovery file there instead :P 4ext is working now, and I'm in the process of flashing ODEX. Crossing my fingers!

Awesome, as long as you did a full wipe you should be good to go after that.

If you still want CM10.1 after this, I've got a guide that can help you get there with S-OFF.

It finished flashing but it still goes through the same constant rebooting process as before Maybe the ROM is bad?

That's odd.

Just to confirm, did you do the full wipe from 4ext?

Only thing I can think to do is to relock your bootloader and run the RUU.

Go into your bootloader again, and do this:
[HIGH]fastboot oem lock[/HIGH]Download this RUU, and run it from your computer.

Yes I did do the full wipe in 4ext. Right now I'm running the program. Hopefully this works or I don't know what else to do.

It didn't work. At the end it said:

ERROR{140}:BOOTLOADER VERSION ERROR

Also, when it detected my ROM and showed the one it was replacing, it showed that I had 1.14 and was replacing it with 1.13 (not sure if going backwards is a problem). The program suggests that I get the proper RUU (also, the phone in the RUU does not seem to be an Evo V 4G, not sure if that matters or not).

So you are S-ON, correct? I think performing S-OFF and flashing a new bootloader may work for you.

Yeah I am S-ON. Another thing, I noticed that the RUU you linked says Radio-1.06 while the bootloader menu on the phone says 1.09. Also, running that code locked the recovery option, and I can't access it anymore.

All you've got to do is unlock the bootloader again.

Also the reason for the different radio is because you've taken the OTA (that's a good thing), not a problem. The RUU is designed to turn your phone back to completely stock, but it was expecting 1.57.5757 HBOOT, which was my mistake -- I thought it would be successful on the 1.57.0000 HBOOT as well.

I just did some research and found that people have had success with S-OFF on the 1.57.0000 HBOOT, which will allow you to fix your problem most definitely.

I have a guide that will walk you through the process.

You'll need a wire (a paperclip with electrical tape around the middle works best), and to take the back cover off of your phone. It basically consists of running a program and touching wires to specific points on your phone... the guide is here. Just start with Step One.

If you get stuck along the way, just ask. Also, I can help you with TeamViewer if it's overwhelming. Just PM me if you want to go that route.

Yeah, that will work -- in the meantime maybe someone else has some other ideas, but I'm at a loss for what to do other than to S-OFF and get you onto an HBOOT that will flash what you're wanting.

Your main version (mainver) needs to be downleveled in order to flash the RUU. The reason why and what you need to do are in the S-ON section of this post.

You will need to have the bootloader unlocked to flash the zip file, then lock it again before flashing the RUU.

Very nice, glad that worked for you! Now if you want CM10 you're free to do the S-OFF steps required for changing your HBOOT. After working through all of the above I'm sure that S-OFF will be a breeze for you.

My guide here will take you through. Since you've just done the RUU you're good to go starting from step one. Just ignore the part about installing drivers since you've already done that. Unlock your bootloader and you can skip that section too. Any questions about it, please just ask in there and I'll help you out!
