Hello dear /e/ friends,
I saw some Q&A about flashing recovery in this Unlocking Bootloader topic.
My bootloader is unlocked.
But I experienced issues on flashing recovery. I attempted to flash the TWRP img . I can’t start it.
$ fastboot flash recovery twrp-3.3.1-z3c-20200212.img
target didn't report max-download-size
sending 'recovery' (13268 KB)...
OKAY [ 0.447s]
writing 'recovery'...
OKAY [ 0.887s]
finished. total time: 1.334s
$ fastboot boot twrp-3.3.1-z3c-20200212.img
downloading 'boot.img'...
OKAY [ 0.460s]
booting...
FAILED (remote: dtb not found)
finished. total time: 0.531s
As you can see, the target didn’t report max-download-size message looks suspicious.
I tried this command
$ fastboot flash -S512M recovery twrp-3.3.1-z3c-20200212.img
I tried working out what it means but as far as I can tell the -S512M part seems to be relevent to the size of the partition or data its sending.
If anyone know what the function of -S and 512M is exactly it would be nice to know.
Anyway, it doesn’t work. I can’t start recovery.
I also tried several e-recoveries… No more success
$ fastboot flash recovery recovery-e-0.17-q-20210530117214-dev-z3c.img

Statring the powered off z3c device with volume up button is inefective.
Statring the powered off z3c device with volume down button starts android.
adb reboot recovery
