I’ve got adb in my home directory.
typing adb brings up a host of commands.
Plugged the phone in and typed
phone switches on.
It says ODIN MODE on the top of the screen. There is a host of other information and the wee green Android man in the middle of the screen. It says ‘Downloading…Do Not Turn of Target’.
There is no prompt for USB debugging. This has been previously selected.
then, ‘fastboot oem unlock’ < waiting for device >
nada so …‘fastboot oem unlock-go’
That means you haven’t unlocked the bootloader yet ?
Ok, that’s really worst, because that’s the really first step.
I don’t know how the unlock should work on your device. So iy.s the best you will first search xda or the web for the unlock procedure. And when your bootloader is open, you can start as i have written before
I’m old schooled guy and i’m using since Android Froyo flashing via custom recovery. In early times it was cmw recovery and today it.s twrp.
I prefer twrp because for me flashing via fastboot is much easier
Okay @gbar, to install ADB & Fastboot on Ubuntu systems is not difficult, because as the packages are available with the default Ubuntu repositories. To install both the ADB & Fastboot, execute the following command from the terminal:
@harvey186, a few months ago I had no idea about flashing an Android Custom ROM. It gives me pleasure to deal with this topic. Inevitably I have read many experience reports and instructions and then tried out.
In the meantime I flashed four different (hated by you) Samsung and two LG devices on LOS, LineageOS-for-mircoG and /e/ OS. I didn’t follow the flash instructions of LineageOS and /e/ (both are the same like an egg).
Heimdall and also Linux have left quite fast behind. I’m an old Windows(ianer). Samsung’s ODIN has always led me to install TWRP on a Windows PC.
With LG I learned how to use ADB and Fastboot - and also used them successfully with Samsung devices, e.g. to delete pre-installed /e/ apps on unrooted devices.
I appreciate the tips of other users. But I learn the most when I do it myself. At the moment I get along well and like to share my experiences. It is in the nature of things that other users have made different experiences.
