This is exactly what @Roboe meant I think! (It also makes sense, despite that info :wink: )
I hope this can be fixed soon :slight_smile:
I will stay close to the Porting threads of the forum^^

Hey Lazalatin,

you’re not alone. I just received my FP2 yesterday, also a delayed delivery. Software version was FP2-gms-17.07.6.1 Today I tried to flash a recent TWRP (3.1.1-0) from the official TWRP site. When trying to enter the recovery mode with this, I get a blue screen too. Also, as you mentioned, the TWRP included in the fp2-sibon release works on my phone. After reading this thread I tried the newest available LineageOS build (lineage-14.1-20170808-UNOFFICIAL-FP2.zip) with the same result: a blue screen.
So I guess we have to wait for the new LCD driver to be integrated into TWRP and LineageOS.

So we’ll have to summon @z3ntu here too, he’s the maintainer of the FP2 TWRP-Port. :wink:

Great!
Thank you @z3ntu :slight_smile:

I merged in the new changes for the kernel. It would be good to give it a new try. There’s also a new panel support or something like that. @z3ntu you should also do new twrp then :slight_smile:

I tried basing TWRP on the omnirom 7.1 branch (with modified lineage device and kernel) but the resulting recovery.img doesn’t boot at all…

31

Can you please flash the recovery.img from https://private.z3ntu.xyz/fairphone/TWRP_3.1.1-0-new-kernel/ to your recovery partition and report back if it’s working? Thanks.

Kudos to you, it works!
My hopes and dreams have been heard and fulfilled! :heart:
Much love to you all :slight_smile

EDIT: Is this new version still backwards compatible for all FP2?

Yes, it works on my phone too :slight_smile:

I installed this new image, and TWRP still works (with encryption, too).

Since the TWRP version number is still the same … In TWRP terminal uname -a is giving “Linux localhost 3.4.0-gea459bc #1 SMP PREEMPT Sat Aug 12 23:00:45 UTC 2017 armv7l GNU/Linux”

I’m not too involved with Linux yet, but the date in there sounds like it really is the new kernel, right?

35

Yes. I built the kernel yesterday. You can even see the hostname if my computer when running cat /proc/version in TWRP. :wink:

36

Just tried, works like a charm. Thanks for your effort.

37

Does this build work for both hardware? If yes: then I’ll update the instructions for OTA.

38

I think it is:

So it seems to work for both hardware revisions indeed :slight_smile:

So next step, flashing LOS succesfully. @z3ntu started a build with the new kernel included. Can somebody with the new, and somebody with the old hardware test this release?
https://fp2.joutubes.nl/builds/full/testbuild.zip

If this release works for both I’ll make this a OTA release.

Just successfully flashed the current test build (12th August) on my (1 year old) and on my wife’s (1 day old) FP2 :smile:
Thanks a lot @z3ntu @snevas

Thank you! Just to be sure, your wife’s phone had the blue-screen issues before?
