Official LineageOS 20 FP4

What key combination can be used to do hardware tests on Lineage OS? In Fairphone OS it goes yes with: * # * # 2 8 8 6 # * # *

There is no such code in LineageOS.

Yep, happens to me twice a day since latest update.
Very hard to purposely reproduce though.
Thanks for reporting it!

I am not sure if this is true. Yes, there is a ( obviously malfunctioning) rollback protection that can brick your device. BUT: I think what is important is the monthly Android security patches and not the main Android version in general. So I think you might be able to revert to the default OS if you have, say, LOS 20 (Android 13) March security patches installed. And there is a FPOS (Android 12) version with April security patches available…

Yes it’s right. It’s the security patch which is important. I have contacted the support of Fairphone and they have confirmed that. The security patch of FPOS need to be equal or higher of the security patch onf LineageOS to roll back and relock the bootloader.

I have tried on a second device to roll back from lineageos (Android 13) with security patch of March 2023 to FPOS (Android 12) with security patch of March 2023, and then relocked the bootloader and all was OK.

I hope that it can help to have this issue solved.

If someone understand how to reproduce it, please share it to add the information to the ticked

Not worked for me. Was running A13 iode with security updates of March updated to FPOS12 with March security and cannot lock. So someone at FP needs to get things straight. My only other thought is the custom key that gets added by iode at the beginning. If FPOS doesn’t delete this then I’ll delete and see what happens!!

[yvmuell]

You have to delete the Iode custom keys before manually installing FPOS again, at least it was the case in the past.

Fairphone stuck in fastboot mode - bootloader unlocked

@LoupStyle If you’re going to install FPOS as a clean install and you are running in the same problems then me, do two things: before you begin with the FP script in bootloader fastboot erase avb_custom_key fastboot --disable-verity --disable-verification Then modify the flash_fp4_factory.command script: # Toggles AUTO_REBOOT="true" # Control reboot behavior. Default is "true" DATA_WIPE="true" # User data wipe. Default is "true" DRY_RUN="false" …

[srdempster]

Thanks for your quick reply. My plan is to revert fully to stock and relock. Was impatient for A12 so played around with LOS 20 and then flitted between Calyx and iode. I just want to reset to stock and lock now, so hopefully the steps you’ve given me will now successfully do this

[srdempster]

Doesn’t work and the 2nd command that disables verity needed an extra command on the end which was flash vbmeta vbmeta.img It seems that Calyx and iode know how to be able to lock the bootloader it’s just a pity that FP don’t.

Hi folks!

Has anyone successfully used the new Android 12 binaries to build LineageOS?
As far as I understand, there are some files missing that were present in Android 11.

Cheers,
Alex

Hi y’all,

I am running LOS and I noticed that the call volume is always very high. The volume control does not seem to have any effect and it appears to be always at maximum volume. Do more people experience this? And where would I report such an issue?

[2allseew]

I’ve noticed the same thing with my volume. If you want to report it, you probably need to open a bug report with Lineage.

https://wiki.lineageos.org/how-to/bugreport

[lriesebos]

See FP4: cannot change call volume (#5763) · Issues · LineageOS / issues / android · GitLab

I noticed that the Messages app that comes with LOS 20 does not include a feature to search through messages. What other apps are people using for SMS/MMS on LOS20 that support searching? (And will handle unencrypted sms/mms – I’ve read that support for unencrypted sms/mms has at least been deprecated from Signal if it is not already removed)

You could give QKSMS a try:

Hello there,
I just bought a FP4 and I’m thinking about installing https://lineage.microg.org/

I’ve done it a few times on FP2 without any issues, but still I like to read forums before jumping. And I see many people have bricked their FP4 at the step where they re-lock the bootloader after installing a custom ROM.

So I thought I’d ask a few questions before trying my luck as I really can’t afford bricking my phone. And if there’s not a zero risk path then I might simply not follow through.

• How important is it to lock the bootloader?
• At the moment, I’m on Android 11 with latest security patch from Jan. 5th 2023. Is is safe to use the image here which looks from Apr. 10th?
• Should I use the recovery from available in that same repo or something else?

Thanks for your dear help

[hirnsushi]

If you plan on installing LOS and want to lock your bootloader you’ll have to build your own images, that’s not supported by default.

@ImaCrea

How important is it to lock the bootloader?

Large parts of the Android security model rely on a locked bootloader and there are apps that won’t run if it’s unlocked.

There are several other ROMs (/e/OS, DivestOS, CalyxOS, iodéOS) that will let you lock your bootloader, but whatever you do check that fastboot flashing get_unlock_ability returns 1 right before you lock it!

Oh and welcome to the community BTW

[B_Jay]

Did anyone experience Dual SIM issues or (dual) WLAN Call issues?
Specially Telekom.

Have problems with that and hope LOS could be a solution.

@rca Just installed the most recent Lineage for Microg. Happy to report that I seem to no longer have the issue with needing to toggle the speaker phone button after a reboot in order for people to hear me on a call.

[rca]

@2allseew Thanks for the update - that is fantastic to hear! I will try to install the update this coming weekend.

At the moment, I’m on Android 11 with latest security patch from Jan. 5th 2023. Is is safe to use the image here which looks from Apr. 10th?

Yes, you should be safe regarding the security-patch-downgrade issue if you go with e.g. lineage-20.0-20230604-microG-FP4 - but still: always check fastboot flashing get_unlock_ability as mentioned by @hirnsushi
If you are interrested in some advanced features as e.g. an system-integrated adblocker then take a look at iodéOS. It’s basically LineageOS+microG+Adblocker and some other cool features, advanced privacy (german article) and so on

@ImaCrea

Should I use the recovery from available in that same repo or something else?

Always go with the recovery provided by the OS devs (LOS4microG, iodéOS…)
