I have a OnePlus 5 and it won't boot. The phone is stuck on a black screen and blue LED (can't boot) since 20 days ago, and I tried everything I saw on the web to make it boot again.
I tried :
- to flash the recovery with the original one
- to flash the Oxygen OS and the Hydrogen OS via fastboot (authorized even with a locked bootloader)
- to use MSMDownloadTool (a tool I found on the web, used by the support of OnePlus to reinstall bricked phones.
...but nothing helped.
I'm now with my OP5 soft-bricked, but since I used MSMDownloadTool, it locked itself (the tool locked the bootloader) and I can't flash again with fastboot (except the official ROM but still won't boot) nor adb. I tried fastboot oem unlock
but I got an error (because I can't go on the developer's options due to the phone not loading): FAILED (remote: Flashing Unlock is not allowed)
If it gets you some info, I did fastboot oem device-info
and got this result:
(bootloader) Verity mode: enforcing
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
(bootloader) enable_dm_verity: true
(bootloader) have_console: false
(bootloader) selinux_type: SELINUX_TYPE_INVALID
(bootloader) boot_mode: NORMAL_MODE
(bootloader) kmemleak_detect: false
(bootloader) force_training: 0
(bootloader) mount_tempfs: 0
OKAY [ 0.001s]
Finished. Total time: 0.002s
Is there any solution to be sure to write again everything on the OP5? (it seems that the MSMDownloadTool and fastboot won't erase everything as the OP5 finishes properly new installation but boot loop every time).
The present state of the OP5: bootloader locked, official recovery working, official ROM installed but won't boot.
I'm on Mac and Windows btw.
