my device got broken but i am still able to connect usb in the stock recovery mode.
if i try to start a shell via adb while the device is in recovery mode, i fail. my terminal echos the line: "error: "Closed".
i think, because this device isnt rooted/cfw, the official firmware blocks the shell access in recovery. but there must be a way to connect.
what could i do to open a shell on this device?
just reinstalling another OS through sideload isnt a option, the only way to access data is through adb
-there is a option in the recovery: "update via adb/sideload". when i choose this mode i can execute via adb a sideload update. the device recognizes the file and executes it. - if try this with the same setup but another rooted device, i success.
fastboot boot twrp.img
. Btw: you can check withfastboot devices
resp.adb devices
whether a device is visible to the corresponding tool.
