Probably you can’t edit posts older than a certain age. I’ve edited it for you, if you aren’t happy with it feel free to reply here or by PM.

Unfortunately there is no edit-icon under the post

Can something be done about this?

[paulakreuzer]

I made it into a wiki.

@k4y0z if that is not the ideal solution (others can edit now too) I can undo it when you’re done editing and re-wikify again if you need to edit again.

[k4y0z]

Thank you @paulakreuzer and @AlbertJP
I guess a wiki works for now, if I see any problems with it, I’ll contact you again.

Although generally it would be nice not to have a time-limit on editing normal posts (or at least increase the time, if that’s possible).

I just joined the forum and wanted to send a big Thank You for creating the TWRP version for FP3! I got my Fairphone in February and was able to run Resurrection Remix thanks to your work. Great to see your stuff got merged into upstream and also that it enabled other people to create more custom ROMs for the FP3 (I’m now running LineageOS ).

I can’t get to twrp on my phone. Maybe a stupid question, but do you get into twrp in the same way as in the PF2?

‘2. Start TWRP by keeping volume up and power pressed for 10s or so during power on. If you boot it for the first time, it asks to enable write permission for the system partition, which is not needed for updating TWRP.’

Porting TWRP recovery

As mentioned, I think the wiki post should be restructured to serve as reference documentation. I’ve put a proposal for this below, unless anyone objects (@Max_S or @z3ntu in particular), I’ll go ahead and apply this proposal. I moved the historical porting notes down, and marked them as such. I rewrote the top of the post, to help new users find out what TWRP is and how things work. I rewrote the upgrading instructions a bit, so they should apply for FP Open OS too. I added a section on Upgra…

And if so, does this mean that twrp is not permantly installed on my phone?

tnx!

Used to the Fairphone 2? Don't do these Fairphone 2 things on the Fairphone 3!

It’s not uncommon that users switch over from the Fairphone 2 to the Fairphone 3. The Fairphone 3 got some things which resemble things many users know how to deal with on the Fairphone 2, examples: TWRP is available. Installing a stock version of Fairphone OS is possible (Fairphone way / community way). Custom ROMs are available, e.g. /e/, LineageOS or GSIs. The Fairphone 3 is different from the Fairphone 2, however, and so not every prior knowledge carries over well to the new device. He…

I had the same error-code as Stefan
(FP3,root,TWRP3.4) I choose every partition to be backedup except “SD-EXT”

I:Find_File: Error opening ‘/sys/class/backlight’

Backup Failed. Cleaning Backup Folder.

I checked and the filesystem on the SD-Card is exFAT, and there is enough free space.
Any idea what’s wrong?

For comparison I tried a backup without the Partition “Data (excl. storage)” which got through without an error.

[k4y0z]

It looks like your data wasn’t decrypted properly and can therefore not be backed up.
Did you decrypt successfully?
Are you using multiple user-profiles or apps, that would create a separate user-profile?

[grumpy]

That indeed looks like the problem I had here: TWRP for Fairphone 3

[k4y0z]

TWRP 3.4.0 should support multi-user decryption, although I haven’t tested it myself.
AFAIK you need to decrypt additional profiles separately via the menu.
If you want to give that another go, and let us know if that works.

Yes, that was the issue, when I tried another time, TWRP opened a prompt for the pw, decrypted the int. storage and the backup went smoothly.

[biafra]

Can I use this TWRP for the FP3+?

[StevenHachel]

yes, you can.

[elossa]

Is there a more user-friendly way to backup my FP3 before installing /e/?

[Alex.A]

I invite you to read the #dic:backup manual on the forum. You could use Titanium Backup (Play Store) or OAndBackupX (F-Droid). But myself I have tried neither.

Hello,

That’s a great news, but how?

I used adb reboot fastboot then
fastboot --set-active=a fastboot boot twrp-3.4.0-0-FP3.img

but the result is:

creating boot image...
creating boot image - 10240 bytes
Sending 'boot.img' (10 KB)                         OKAY [  0.028s]
Booting                                            FAILED (remote: 'dtb not found')
fastboot: error: Command failed

Think I need some help.

Thanks for any advice.
Thanks for all the great job the community accomplished.

Hi,

“fastboot boot twrp.img” works for me.

Steven

[jfoucry]

Well not for me, but I succeeded to root my FP3+. I am writing a tutorial right now.

Thanks.

This looks like your boot.img is not the correct file: creating boot image usually appears when the file does not have the correct header. Also 10KB is way to small for the boot image.

I get:

fastboot boot twrp-3.4.0-0-FP3.img 
Downloading 'boot.img'
