Fairphone 3 (FP3)

@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 just an updated camera module in it, no?
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.
-
@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...
-
@Luksus my Android is 10.
why shall i downgrade to android 9 ? i use TWRP

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+.
-
@007fred50 because the port and GSI is based on Halium 9, which requires Android 9.
-
@Luksus how can i downgrade my OS ?
-
@007fred50 I assume you just need to flash a stock rom:
https://forum.fairphone.com/t/twrp-installable-stock-firmware-packages-for-fairphone-3/57219download (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).
-
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. -
@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?
-
@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.
-
@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)
-
@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.0111But, 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". -
@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)
-
Please just save this script in the folder, where the unzipped images are.
Then boot the phone into fastboot mode.
Then execute this scriptsh 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. -
@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

Yes. "Just" follow this guide: https://support.fairphone.com/hc/en-us/articles/360048050332
Just to be sure.

Yes
- Install GSI / follow that guide here https://forum.fairphone.com/t/how-to-flash-a-custom-rom-on-fp3-with-gsi/57074
No. After you have a working Android 9 follow my guide:
Flash
- Boot the phone into bootloader/fastboot by pressing power + volume-down buttons until it reboots. Or just reboot and click a volume button within 5 seconds and select the bootloader.
- Flash halium-boot image: $ fastboot flash boot halium-boot.img
- Boot your downloaded TWRP image temporarly:
$ fastboot boot [twrp-image.img] - In TWRP, wipe data only
- In TWRP go to ADVANCED and Select "ADB Sideload". Activate sideload.
- in Terminal:
$ adb sideload [ubports_gsi.zip] - Wait until it finished, then reboot system.
-
@Luksus the link you gave me with Android 9..
it is android 10 (Fairphone_FP3_FP3_9_8901.2.A.0111.20200131_01311418_user_release-keys.zip)
-
@007fred50 is it? ok, then just use the other zip 0110.
