Installation on FP5 - stuck at flashing both on Win11 and Ubuntu

[aibd]

Thank you for the detailed outputs.

@nickd

I’ve been using ./ before the commands btw

Ok, firstly, perhaps you have no platform-tools system installed …
… but I still don’t know for certain if Edit you and the script have access to two different versions of fastboot

@nickd

Nick@NDLenovo MINGW64 /c/platform-tools

So here you are in platform-tools

whereas

@nickd

./flash_FP5_factory.sh

will run the fastboot parts of script out of /your/path/to/IMG-e-2.5-t-20241108446629-official-FP5/bin-linux-x86.

Personally I would really want to resolve this, maybe you feel you have, but of course I cannot see what you can see.

The start of the script tries to ensure nothing is wrong with the environment … to sidestep the script one would have to be really confident in the manual steps.

@nickd

Where can I find a guide to, “the traditional fastboot method” ?

If you take some time to read [HOW-TO] Flash /e/-OS on Fairphone 3 using Debian based GNU/Linux Note it is FP3, you will see towards the end of the OP, just after the short paragraph starting Update May 2023

@Chimpthepimp

From terminal application on PC, navigate to file path where you have downloaded the /e/-OS image, for example like cd /path/to/your/extracted/files/ on some machines a right click in the folder allows to open it directly in a terminal. Execute the following commands to install /e/-OS:
fastboot flash system system.img
It will result in the following output on PC:
… {continues}

Back to your FP5

Compare the above with the contents of your unzipped folder

I found this

$ cd test-fp5/
~/test-fp5$ cd IMG-e-2.5-t-20241108446629-official-FP5/

~/test-fp5/IMG-e-2.5-t-20241108446629-official-FP5$ ls
abl.img        devcfg.img            keymaster.img    uefisecapp.img
aop.img        dsp.img               modem.img        vbmeta.img
bin-linux-x86  dtbo.img              multiimgoem.img  vbmeta_system.img
bin-msys       featenabler.img       qupfw.img        vendor_boot.img
bluetooth.img  flash_FP5_factory.sh  shrm.img         xbl_config.img
boot.img       hyp.img               super.img        xbl.img
cpucp.img      imagefv.img           tz.img

If you felt confident enough you could deconstruct the script and take just the install lines from line 114 - 148 as guidance and flash each of the .img files to the relevant partition.

Late edit Inspired by this in the script:

    echo "ERROR: Could not flash the ${2} partition on device ${1}."
    echo ""
    echo "ERROR: Please unplug the phone, take the battery out, boot the device into"
    echo "ERROR: fastboot mode, and start this script again."

You might consider, with the phone unlocked, and briefly checking that the existing OS seems to run correctly, shutdown and removal of the battery – before a fresh start.
