Fairphone 3 (FP3)

007fred50 · 3 Nov 2020, 16:29

@Luksus i downloaded the file and

fastboot flash boot halium-boot.img
but still stuck in boot logo (fairphone 3+)

Luksus · 3 Nov 2020, 16:36

@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 · 3 Nov 2020, 16:37

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

007fred50 · 3 Nov 2020, 16:40

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

Luksus · 3 Nov 2020, 16:41

@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 · 3 Nov 2020, 16:45

@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 · 3 Nov 2020, 19:03

@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 · 3 Nov 2020, 19:45

@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+.

Luksus · 3 Nov 2020, 19:55

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

007fred50 · 3 Nov 2020, 19:58

@Luksus how can i downgrade my OS ?

Luksus · 3 Nov 2020, 20:10

@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 · 4 Nov 2020, 08:30

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 · 4 Nov 2020, 08:57

@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 · 4 Nov 2020, 10:18

@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 · 4 Nov 2020, 12:01

@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 · 4 Nov 2020, 12:41

@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 · 4 Nov 2020, 13:37

@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 · 4 Nov 2020, 16:37

@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.
