I couldn’t quite follow you there, but broken Wifi, usually coupled with no sound and a hot phone, is usually due to running an outdated kernel. The current software version is A.116 but as of now FP only provides the A.107 kernel for manual download.
You should not manually flash a kernel, but use Magisk to patch the currently running kernel from within Android
You shouldn’t flash a A.107boot.img to a device running A.116, next time just follow these simpler steps to perform the OTA update:
I have already uploaded a patched boot.img for the latest release here:
If you need a stock boot.img from A.0116 I can upload that as well.
As a general rule, don’t flash any boot.img if you don’t have to, just follow the original root guide, it’s still valid.
@anon9989719 nice thought , but that’s only the ota.zip file. There is a boot.img“hidden” in there but it’s unnecessarily hard to get it out, copying one from a already updated system is way easier
Thank you @hirnsushi. I have restored images with Magisk, then tried to update as you wrote, without reboot FP4. Here is logcat.txt : logcat.txt - pCloud

This could mean that the delta update payload was targeted for another version, or that the source partition was modified after it was installed, for example, by mounting a filesystem.

You need to flash a matching dsp.img, not sure I have that one backed up, I’ll have a look
If anyone reading this didn’t upgrade to the newest release already, now would be a great time to dump some partitions
Normally I’d say wait for someone to dump a partition with the correct hash, but I’ve checked every dsp partition / dsp.img I have and all of them, every single one, including the factory images have the SHA256 hash 8b52788ea43f580b6641b78170df42908b5c39b8c23d54b0d749ed37f5931a73.
So either you were on an ancient build before (for which I deleted my backups) or something else is going on here
Whatever it is, it’s not directly related to Magisk, that only touches boot.
What Magisk modules did you install, did you run any other scripts with root privileges that could have altered your system?
This is my second FP4 and I didn’t brick it like I did with the first one. I just rooted it following your instructions and I applied the OTA until now, but following @rar0 instructions in this topic. Present build number is: FP4.FP3W.A.128.20220516
LSPosed might play a role here, not sure why it would touch dspI don’t see any audio module here.
Did you install any additional LSPosed modules?
In any case, I’d first try a reboot to get rid of all the “systemless” changes that might still hang around and start the update again after that.
That also means you’ll have to reroot manually again once (if) that’s successful.
We could try to figure out what happened on the 25th of June…
07-12 10:16:52.117 1493 1493 W update_engine: [WARNING:mount_history.cc(66)] Device was remounted R/W 1 times. Last remount happened on 2022-06-25 04:31:39.000 UTC.
…when the dsp partition got mounted R/W for some reason, but honestly I’d nuke and pave at this point.
Who knows what else got changed on your system, better to start fresh from a clean slate.
This might be fixable or we might chase one edge case after the other, but without a matching dsp.img there’s no use in trying to figure out what caused it.
I’d say perform a fresh install and if you run into that same problem again down the road we’ll have to seriously look at possible causes.
I’ll upload a Magisk patched boot.img in the meantime so you can at least get rerooted faster Edit:FPOS-A.142_magisk_boot.img
I’ve uploaded you a patched A.128 one here, there’s a folder with all my previous patched boot.imgs as well and you can always get specific stock kernels on Fairphones kernel page and patch them yourself if necessary.
