I've clearly done something stupid and desperately need your help!

I have a brand new OnePlus 3T that I've managed to get stuck in a bootloop. I can access fastboot but no recovery or system. OEM is unlocked.

Things I have done:

  1. Tried to install TWRP recovery. Fastboot says this was successful, but I haven't been able to boot into it.
  2. Tried booting directly to TWRP recovery img. This freezes the phone and it says FAILED (too many links) in fastboot
  3. Tried installing stock OP3 recovery. Same problem as before.
  4. Tried hard brick recovery tool. Everything lights up green with installed:ok but still I'm stuck in this bloody bootloop.
  5. Tried installing ColorOS through the Chinese install tool. Comes up Failed every time.

I am at my absolute wits end trying to sort this out and I literally have no idea what to do. I have been Googling this all morning to no avail.

Any help anyone can give whatsoever would be really, really appreciated.

EDIT: Some additional info from fastboot screen -

PRODUCT_NAME - msm8996
SERIAL NUMBER - b2411609
SECURE BOOT - enabled
DEVICE STATE - unlocked

EDIT 2: more weirdness. I changed the USB cable from a micro USB with USB-C adapter to the proper USB-C that came in the box, and the phone booted into the OS. I tried to download the latest Oxygen update via the software update tool but that just boots me back into fastboot.

EDIT 3: I think it's just my recovery partition that's busted. Tried reinstalling stock recovery and that didn't work, so currently I have fastboot and OS but with no recovery - given that this is a separate issue I'll do some research before asking further questions.

@EHH - thanks for helping me figure this out. Really appreciate your time :)

  • Woow!! you managed to corrupt all bootloader modes ;) You didn't explain how you ended up in such situation. – EHH Jan 9 '17 at 13:47
  • How are you attempting to reboot? fastboot reboot recovery? Please explain exactly how and how it fails, not just that it does. – Matthew Read Jan 9 '17 at 13:50

    @MatthewRead Thanks for replying :) I have tried 'fastboot reboot recovery' as you suggest and also holding power + volume down, each time I just get punted back to fastboot – rozzlemcfrozzle Jan 9 '17 at 13:54
  • also worth noting that I've tried powering on the phone normally and selecting 'recovery' from the boot manager menu, this flashes up the 1+ logo for a sec and then back to fastboot – rozzlemcfrozzle Jan 9 '17 at 13:55
  • @EHH believe me when I say my stupidity knows no bounds. I accidentally ran a script meant for the OP2 and I think this might have been what messed it up. All I was trying to do was install TWRP and CM13!! I feel like an absolute moron lol – rozzlemcfrozzle Jan 9 '17 at 13:56

Boot loop was resolved by using the USB-C cable provided by OP, however the recovery partition seems to be corrupted. Phone works though so nbd, recovery can be sorted out later on.
