Root [CDMA] help! rooted evo 3d stuck on boot loop

joekargl · Jan 31, 2012

i tried flashing a rom on my phone and now it is stuck on a boot loop. i can get on the bootloader, but i cannot go into recovery mode. i cant even do a factory reset, it goes back into a boot loop. it wont show up as a drive on my pc, and the command prompt cant find it either. it always says waiting for device. please help im kind of lost.
Hboot 1.5 S-ON

Turn off your phone. Hold Vol down + power. You should now be in your bootloader. If you're connected with fastboot, you can use your command prompt now. If not, go into recovery and flash a new ROM. Remember to wipe dalvik and cache partition. If you don't have a new ROM to flash on your SD card, you can go into advanced (may be called Mount) and mount the SD card to USB and put a ROM on it.

i cant go into recovery mode, it tries to boot up normally when i do that and then it boot loops again

Sounds like your recovery got wiped. You may have cd wrong when you were flashing. So you can't get into recovery what about bootloader? Does adb work?
Also try another usb cord. You never know.

joekargl · Jan 31, 2012

yes i have tried adb and whenever i try anything it always says "device not found" or "waiting for device..."

Are you able to get into bootloader?

It just sounds like he is not putting it in fastboot mode and only trying adb commands. That's just my thought.

,Boot phone to bootloader highlight fastboot hit power button then plug in usb it should then say fastboot usb once you have done that make sure you extracte
d boot.img from the ROM your gonna flash and put it in your platform tools folder(or wherever you have fastboot and adb.) Also make sure your recovery img is in that folder if you didn't download the disk image go ahead and do that now and put it in your tools folder and rename it recovery to make the command easier. Once you have that in your tools and phone in fastboot type fastboot flash recovery recovery img. Then type fasboot flash boot boot.img now type fastboot boot recovery.img make sure you command into recovery .in recovery wipe dalvic then go to mounts and format system cache and data . now flash the zip for the ROM your gonna use. Then reboot.I suggest just trying A stock deodex till you get this worked out.

If your phone is connected to computer, it will automatically go to fastboot from the bootloader

The device not found sounds like htc sync is not installed or jdk\jre is not installed

Mine will say the same thing when i have it in bootloader but once i select fastboot it will run the command.

joekargl · Feb 1, 2012

so how would i get htc sync back on?

The setup.exe should still be on your pc try reinatalling it will tell you whether or not its installed right now.

DonB · Feb 2, 2012

I agree with Wake, sounds like HTC sync is missing or Java

Please help, I recently rooted my Evo3D using the HTC unlock method. Everything was working great. I tried to install a different kernel and now my phone is stuck in bootloop. I followed your instructions, i'm still stuck in Bootloop but now I can't even get into recovery. When I boot into bootloader it seems to try to load an img file in directory PG86DIAG.zip,.nbh but NO IMAGE!!! Also PG86IMG.zip,.nbh,.tar,.aes,.enc and also NO IMAGE!!! Thanks in advance. I would really appreciate the help.

This happened to me.. It ended up being the rom i was using... i just restarted my phone went into bootloader. Did a restore and i was fine. If you cant get itno recovery from loader open cmd prompt

cd c:\(file your ads and fastboot are in) mine is rootevo3dnew.

then you should see

c:\(location)

then type: fastboot boot cwm-4.0.1.4-shooter.img

that should get you into recovery. good luck

Ok so I have a problem with a htc evo 3d, it's stuck in bootloop too but I have managed to work around it a bit. I extracted the boot.img form a rom I was trying to use and fastbooted it onto the phone, this does temporarily fix the the loop, it will then boot up fine but when rebooting then we have an issue, it then gets stuck in the bootloop again. How can I make the boot image stick so it doesn't get stuck in a loop, anyone?

Brian706 · Oct 15, 2013

What fastboot command are you using?

fastboot flash boot boot.img

Is that the one? Also are you using the boot.img from the rom you're currently using? If you're s-on, people flash the boot.img separately after a rom flash but never heard of anyone having to do it after each reboot.

Orang3Mango · Oct 15, 2013

Thank you Brian706!!!! So what I was doing was "/fastboot boot boot.img" I needed the flash to get it to stick, I'm still very new to flashing roms over to androids and this was my first attempt, I took on fixing a friends phone and over the last week I've been trying to fix it and now I have a custom rom for it for sprint for him. Again this fixed it for me so thank you!!!

Brian706 · Oct 16, 2013

Awesome! I'm glad it's working.

I was wondering if you were possibly booting it rather than flashing. As you discovered, booting it temporarily boots it into the phones memory for one boot where as flashing it makes it permanent.

Same call be done with a custom recovery.

Bonus tip. If you use fastboot boot recovery.img to temporarily boot the recovery, it will save you from having to flash the kernel (boot.img) separately after a rom flash.

So if you use that method to get into recovery and flash a rom, you will not have to then flash the boot.img afterward.
