i allready told the problem in the german section, but as we found no solution to this special problem i would like to post it here in detail for the whole comunity again.
I recently got the new FP3+ and i would like to put /e/OS on it. I successful unlocked the bootloader following the instructions from the faiphone homepage.
I can use “adb reboot” to enter the fastboot mode. Then i´m stuck.
With the command “fastboot devices” the FP3+ is not found and i also can´t use “fastboot flashing unlock”.
I tried the easy installer and via adb with fastboot but the problem seems to be the conection fastboot ↔ FP3+
I think I have to correct this (from the input of the earlier attempt in a German topic). What you did successfully is allowing to unlock the bootloader by entering the unlock code in the developer option on the stock ROM. That is not yet the actual unlocking.
Wow thanks andrelam. That was the problem.
Now fastboot is working. I havent continued yet but i hope now it should work.
Also thanks Ingo for the clarification with the bootloader.
The easy installer wasn´t working because the device had some issues with adb while running on android. But with the now really unlocked bootloader and working fastboot i flashed /e/OS. It is running now smoothly. Thanks again for your help.
I have the same problem on a new FP3+. The device is found on adb devices if its on, but not in the bootloader. Andrelam’s solution did not work for. I see the yellow triangle, but when I let Windows search for the driver in platform-tools it cannot be found.
To avoid the popular adb/fastboot confusion … Please confirm fastboot devices doesn’t work for you with the phone in bootloader/Fastboot Mode.
(The adb command doesn’t work in Fastboot Mode by design, only the fastboot command does.)
I see that I read Andrelam’s guide wrong. I didnt use the option “Let me pick from a list of available drivers on my computer” but instead let Windows search for it in the “platform-tools” folders. I tried it again and now its working, even with the Easy Installer.
When I do that, I cannot find the “Android Device” on the list. Neither a “SAMSUNG Android Phone” like it’s said here… I tried with “Mobile devices” but then I cannot find any ADB driver.
I did install the universal driver for Win10.
By any chance, would you have an idea ? It’s blocking my easy-install ^^’
EDIT : problem solved, the solution is here (TL;DR : FP on Fastboot, Windows update, optional updates, drivers updates, Android Composite ADB Interface)
