Hi All,

used my OP7T for a week before deciding to unlock. That went fine, but when I tried to flash a GSI (no custom ROMs available yet), it says partition not found?? Tried system and system_a.

Code:
[email protected]:~/Downloads/Android$ fastboot flash system system-quack-arm64-ab-vanilla.img 
Sending sparse 'system' 1/3 (786428 KB)            OKAY [ 24.933s]
Writing sparse 'system' 1/3                        FAILED (remote: 'Partition not found')
Finished. Total time: 24.950s
[email protected]:~/Downloads/Android$ fastboot flash system_a Havoc-OS-3.0_ARM64-AB.img 
Sending sparse 'system_a' 1/3 (786428 KB)          OKAY [ 24.953s]
Writing sparse 'system_a' 1/3                      FAILED (remote: 'Partition not found')
Finished. Total time: 24.965s
[email protected]:~/Downloads/Android$

You don't say :D

In the meantime I found the actual solution, here it is for the record : reboot from fastboot to fastbootd using "fastboot reboot fastboot"

And then the commands will work

Got: "fastboot: usage: unknown reboot target fastboot"
been messing all night with fastboot trying to get it to boot to fastbootd
i keep getting this same error and so my phone is currently bricked as i cannot install the
system.img or anything that follows. also tried booting to fastbootd by doing
fastboot reboot recovery but it cannot find reboot target recovery either.

i had the same problem. solved it by flashing msm extended recovery to both slots. that recovery has option to enter fastbootd
 
For my 600th post on XDA, I offer this info in hopes it will help.

This one is T-mobile. Don't know if it will help ort harm but it works for me.

I don't have both hands right now; yoiu'll have to search for yourself on how to enter "EDL" mode and possibly an MSM (or is it MDM?) version of stock flashable file for your model and carrier, else maybe try the T-Mobile one at your own risk: Unbrick Tool for T-Mobile

GOOD LUCK
