RESOLVED: use the exact version of platform tools - see answer below
Hi,
I got a new Gigaset GS290 with Android 10. All steps in the documentation for installing /e/ went as expected until the start of the final section “Install /e/”:
I just did “fastboot flashing unlock”, confirmed on the phone with volume up, got confirmation of success on terminal command line.
Next I wanted to “adb reboot bootloader” as described in the doc,
BUT now adb says that there are no devices.
On the phone screen I see in tiny font in about the middle of the screen the Select Boot mode choices and in the last line it says “=> FASTBOOT mode …” but nothing else happens from here.
All buttons seem to be dead. As a final option, I tried to reconnect USB cable, but neither effect.
I have no clue how to revive the device from here and make it visible again to adb?
News->
“fastboot reboot” helped me boot the device from there. I’ll see where I can continue.
Suggestions still welcome, not sure what I did wrong, according to the instructions.
Second try - moved through steps again. Now here:
$fastboot flashing unlock
(bootloader) Start unlock flow
OKAY [ 26.417s]
Finished. Total time: 26.417s
$ fastboot flash --disable-verity --disable-verification boot boot.img
terminating with uncaught exception of type std::out_of_range: basic_string
Abgebrochen (Speicherabzug geschrieben)
translated: canceled (wrote memory dump)
So this time I went right to the next step which fails, but the file boot.img IS in the current directory.
Any idea?
BTW fastboot version 31.0.2-7242960 - i.e. newer than in your documentation.
A problem? I downloaded as described. I am on ubuntu
Thanks, Marcel
