1.6.8 works with papatitas tool.
if you dont have any connection / range issues, leave it as is
elswhere: force downgrade to 1.5.7 :
2 methods:
method 1)
remote and copter battery must be at least 50% full
format sd card with dji go
fresh downloaded P3C_FW_V01.05.0070.bin (if old one is corrupted)
via pc on sd card,
remote and copter off, hold link button on copter, switch copter on
(leave remote off) still hold link button! when gimbal starts to beep
and gimbal led alternates red/green, release link button and wait approx 20 minutes
until gimbal led is solid green,
powercycle remote and copter,
if necessary link remote to copter
method 2)
remote and copter battery must be at least 50% full
format sd card with dji go
fresh downloaded P3C_FW_V01.05.0070.bin (if old one is corrupted)
via pc on sd card,
remote and copter off, switch on remote, wait a few seconds,
switch on copter, start dji go, wait for connection, open camera view but dont do anything else, put sd card in copter,
gimbal beeps and gimbal led should start alternating red/green, wait approx 20 minutes until gimbal led is solid green.
powercycle remote and copter,
if necessary link remote to copter
if both methods dont work or remote wont bind:
if it doesnt do anything, post the generated logfile
(its on the sd card)
if the update starts, but is cancelled ( one looong beep)
just try it again a few times
it it still doesnt work:
remote and copter battery must be at least 50% full
switch on remote, wait a few seconds,
switch on copter, start dji go, wait for connection,
start upgrade via dji go (internet required):
not in camera view but in opening screen press the hat symbol in the right upper corner for about 10 seconds, then select a firmware upgrade (1.6.8)
it will update only the parts that arent this version, especially the remote itself.
wait until its downloaded
and do the upgrade (dont interrupt)
after that you can try to downgrade to 1.5.7. with method 1 oder 2 from above.
if necessary link remote to copter
if it doesnt work, post the log.
it it works, dont forget to check the settings in the app and calibrate remote, gimbal, IMU, compass.
Did all of them. Still no luck.. log says Downgrade is not availible. stays on 1.6.8 Now i need a tester that has no problem patching on 1.6.8 cos this thing can not be downgraded anyhow. Tested on 5 other copters and all work fine on downgrade. But this one Updated again/tryed 3 sd's/ method 1-2-3 nothing works. Also i see a strange thing about this quad, the battery lights blink so slowly. even i tryed to update the (battery only) on my p3pro, it says updated, but still blinks slowly
