[FIX] & [DOWNGRADE HBOOT] - Stupid Bootloop with HBOOT 1.58 EVO 3D - UPDATED 1-7-13

My friend's phone had the annoying bootloop problem. I'm posting this because after a lot of searching, I found nothing to fix the bootloop, just people asking about it. Here's a simply fix.

BOOTLOOP FIX:

If you already tried unlocking/ and you're still S-On, then set everything back to stock:

Flash the attached stock recovery,

fastboot oem lock to be locked again.

Use the latest RUU to update the phone.

At this point the stock, locked phone should function normally.

I have busted this phone a ton of times trying to get different recoveries and roms to work, and this method has always fixed the bootloop.

At this point you can try whatever tutorial you like to downgrade or customize the phone...and if it breaks, hopefully this method will still work for you. If it doesn't work the first time, try running the RUU a second time. Or third. :)

CUSTOM RECOVERY:

If you want to unlock and install custom stuff:

Use the HTC Dev unlock method.

Fastboot install CWM Recovery v5.8.0.1 from their website -

The ONLY recovery that I've found to be compatible with HBOOT 1.58 is CWM v5.8.0.1. Everything else leaves the phone in an infinite bootloop. Maybe others have had different experiences.

To fastboot install the CWM recovery, rename the file to recovery.img (for simplicity) and type in a command prompt (same directory as fastboot and recovery.img):

fastboot flash recovery recovery.img

Then, to enter into recovery, either pull the battery and enter recovery through the bootloader menu, or type in:

fastboot boot recovery.img

This should get you into the working CWM recovery. If it doesn't, it's because HTC hates people that buy their phones.

If you feel like giving up and running stock, all you need to do is reflash the stock recovery, and relock the phone using fastboot oem lock - and now it should run the stock rom...and if it doesn't, then rerun the RUU. Tedious.

HBOOT Downgrade & S-Off:

If you have: Stock 2.89 RUU / Locked / S-On

Unlocked with HTC Dev method

Flash CWM 5.8.0.1 from the CWM website:

fastboot flash recovery recovery.img - then

fastboot boot recovery.img (to enter recovery)

Flash the SetMainVersionLOW.zip file attached (thanks ramjet73)

Relock the phone with: fastboot oem lock

Use the Unknownforce/closeone hboot downgrade with live CD using the 2.89 RUU's rom.zip (from windows temp folder) renamed to PG86IMG.zip - go to the Unknownforce/closeone thread for this part: http://xdaforums.com/showthread.php?t=1563342

Then flash the standard 1.13 RUU on your windows system (may also work with the PG86IMG.zip method, have not tested)

Then use revolutionary 0.4pre4 to S-Off

Finally, you need to flash a custom recovery which you can do from revolutionary, or from fastboot as listed above. Once the recovery is installed, you should be able to install a compatible custom rom and kernel.

You bootloader screen should now say REVOLUTIONARY on top instead of UNLOCKED or RELOCKED etc... and show HBOOT 1.40.1100.

Thanks to Unkownforce, closeone, and ramjet73 for making this possible.

PS. Screw up your phone at your own risk. :)
