@007fred50
wait, what is that? step6: install image inside ubports_GSI_installer_v10.zip->data->system.img

You just should install the whole zip over the sideload function.

007fred50

@Luksus so i dont need step6? and what is (sideload function.) ?

007fred50

@Luksus but are you sure it will work on (fairphone 3 plus) ???

Luksus

@007fred50 did you read the "Flash" section in the first post?
You just need to follow it.

I have no reason, to believe, that it would not work on FP3+.
It's just an updated camera module in it, no?

007fred50

@Luksus i buy the phone as (Fairphone 3 +) no upgrade

i just flash boot first. then twrp with ubports_GSI_installer_v10.zip

@Luksus said in Fairphone 3 (FP3):

It's also a new audio module. And IIRC from the live event Q&A session of the FP3+ launch there's probably also "some" change in the core module (because they said upgrading the audio module wouldn't have an effect on the FP3).

But then, the hardware related changes should be in the vendor partition. So if I understood the concept of GSI correctly, the GSI system is supposed to work.

Luksus

@Ingo I can't find any information about core-module differences, only something about improved "audio performance". This could just mean the 2db more output on the sound-module or something different...

@007fred50 it comes to my mind, that the FP3+ is shipped with Android 10. Is that the case, in your case? If so, you would need to downgrade to Android 9, before trying to get the GSI running...

007fred50

@Luksus my Android is 10.

why shall i downgrade to android 9 ? i use TWRP

@Ingo I can't find any information about core-module differences

I'm not aware of any written information about it, either. They ran two Q&A live video sessions (IIRC on youtube and facebook). It must be somewhere in those streams.

About downgrading: the new modules are not supported with Android 9. Several people learned that the hard way when they installed the /e/ version for FP3 based on Android 9 on their FP3+.

Luksus

@007fred50 because the port and GSI is based on Halium 9, which requires Android 9.

007fred50

@Luksus how can i downgrade my OS ?

Luksus

@007fred50 I assume you just need to flash a stock rom:
https://forum.fairphone.com/t/twrp-installable-stock-firmware-packages-for-fairphone-3/57219

download (I would take the second one), unpack, boot phone into fastboot, execute flash_stock.sh, reboot to fastboot, flash_stock.sh again (to flash a- and b-partitions).

Ingo

Found something about the core module: https://forum.fairphone.com/t/speaker-module-from-fp3/64728

~~At the moment the Fairphone Forum is down for maintenance, though.~~

007fred50

@Luksus I have downloadeed the file (Fairphone_FP3_8901.2.A.0110.20200109_01092024_user_release-keys.zip)

How can i install it on my phone? does i need TWRP or software / how?

Luksus

@007fred50 No, nothing with twrp, please read my instructions carefully:

download (I would take the second one), unpack, boot phone into fastboot, execute flash_stock.sh, reboot to fastboot, flash_stock.sh again (to flash a- and b-partitions).

As List:

Download
Unpack/Unzip
Boot phone to fastboot mode
execute flash_stock.sh from the unzipped download
wait until it is finished
reboot phone to fastboot mode
execute flash_stock.sh again
reboot
(9. wipe data partition, when you are asked for)
If it boots successfully into android, just reboot and follow the steps for installing GSI again.

007fred50

@Luksus there are no flash_stock.sh inside the file / Zip

wrong file/Zip downlaoded? (Fairphone_FP3_8901.2.A.0110.20200109_01092024_user_release-keys.zip)

Luksus

@007fred50 sorry I forgot, how the things work together:

In this github-repository there is the script to flash the files contained in the zip. There is also the stock-rom version linked, which I used:
A.0111

But, I also read, that it should be possible to flash the zip with twrp.
Please try to follow these instructions: https://forum.fairphone.com/t/how-to-flash-a-custom-rom-on-fp3-with-gsi/57074 in the first post at "Flash back stock ROM".

007fred50

@Luksus can't get it to work here is my steps:

cd Fairphone_FP3_FP3_9_8901.2.A.0111.20200131_01311418_user_release-keys/
fastboot flash system system.img
fastboot boot twrp-3.4.0-0-FP3.img
adb disable-verity
fastboot -w
fastboot reboot
fastboot flash boot halium-boot.img

I can't get thiss to work:

adb shell mount /system_root
adb push treble-overlay-fairphone-fp3.apk /system/overlay/

It stuck on boot up logo (Fairphone 3+ Logo)

Luksus

@007fred50

Please just save this script in the folder, where the unzipped images are.
Then boot the phone into fastboot mode.
Then execute this script sh flash.sh
If it succeeds, boot the phone into fastboot mode again.
Execute the script again.

Do not use twrp or flash any GSI, before you have a working android again.
Please refer to Fairphone Forum, if you have issues, to get a working android again.

007fred50

@Luksus but that will replease all files inside (Zip).

Can i go back to Farphone OS again? (Android 10)

Just to be sure.

install Fairphone OS / Android 9
Install GSI / follow that guide here https://forum.fairphone.com/t/how-to-flash-a-custom-rom-on-fp3-with-gsi/57074
