I’ve just got my new FP4. As I was under FPOS on my old FP2 I really wanted to install something like IodéOS. But I’m a big newbie in all sort of code and stuff. I progressed slowly, read all the tutorials and help topics and reddit messages I couls for days but I can’t solve my problems. Here they are
I unlocked bootloader via the instruction on the fp page, multiple times, but everytime I reboot to bootloader it stays to “DEVICE STATE - locked”.
Even if the device is rightly recognized to use the adb command, it is not anymore as soon as it comes to the “fastboot” steps. The command get stuck on “waiting for any device” while one second earlier it was well detected. Basically I didn’t manage anything fastboot / flashing related.
When I got to the adb sideload step, it did work until 47% of the transfer, where each time I got : “E:footer is wrong
Updage package verification took 0.0 s
E:Signature verification failed
I saw many subject on this on the internet but can’t fix it anyway.
I’m loosing my mind on this but really don’t want to go back to google Can somebody help ?
I hope i’m understandable, I really don’t know the right words and the pro vocabulary
With the instructions on the FP page you only create the possibility to unlock the bootloader: " Enable OEM unlock".
Unlocking the bootloader itself is done in bootmode with the command: “fastboot flashing unlock”.
Only then the bootloader is displayed as unlocked.
