First of all, I don’t use Firefox on Android.
and secondly, he asked for a privacy friendly one. 
Private. Right.
What’s annoying with Graphene’s reader is that it has no search function.
I only answered one question.
we shouldn’t be using pete’s channel for anything like this.

I sucessfully dirty flashed IodeOS 5.10 today to my device. Thanks to @petefoth for providing it. 
It is running smooth.
Is there anything known whether at some point Android 15/IodeOS 6 will be ported to the Yoshino Platform devices or is this not possible anymore?
Someone is working on it: see this comment in GitHub and downloads in Sourceforge. I won’t be making Iodé6 or los4microg 22.1builds for this devices (and the other devices in the Yoshino-platform family) until this work is more stable. From what I’ve read on XDA Forums ( see latest posts in this thread), it’s pretty good but not really ready for use as daily driver

Hi there.
I just want to update here with a short report about loosing randomly the IMEI on my XZ1 Compact using the IodeOS 5.10 ROM and successfully restoring it via TWRP recovery.
I switched off my phone normally yesterday and when I booted it this morning, I had lost the IMEI again (for the second time, last time this happened in august last year) The symptoms are:
- the SIM card was not detected
- Settings → About Phone → IMEI showed no IMEI anymore
I used the method to fix IMEI again via TWRP recovery as described here.
- Reboot into recovery (If you do not know how to do this, an easy way is: Settings → System → Buttons → Power Menu → Activate Advanced Restart. You can then select reboot into recovery when you open the Power Menu by pressing the power button.
- Advanced → Terminal
- Type two commands:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
There was some error message about full memory (see attached screenshot) but I rebooted anyway.
The fix worked. I had cell phone connection again and the IMEI is showing up in settings again. So this works even if you lose your IMEI on a trip and you have no access to a PC to fix it.
Maybe this post can help some people having similar issue.

I can second this. I had the same problem (again) just recently and your described method using TWRP worked perfect. I had the same error message in the TWRP terminal window as you.

@IamJoosy but also other users with this error:
I posted the same post on the XDA thread for the XZ1C ROMs for Android 14 and one user there gave very detailed technical information what is the background of this error. You find it here.
Indeed, that’s a good explanation about what happens behind the scenes. What this post doesn’t explain though, is what might cause the EFS to become corrupted in the first place.
I’ve updated to 5.11
Everything seems to work !
Thanks a lot

Thanks very much for writing this (and supplying that link as well). This actually just happened to me and the commands worked for me (run via ADB since the LineageOS recovery I’m running offers no terminal).

Hi all. I noticed today that my IMS Features (VoLTE / VoWIFI) stopped working. I was on IodeOS 5.10
I was supposing that this might be connected that I recently fixed my corrupted EFS config (no cell phone connection, noIMEI showing up etc) via TWRP Recovery and terminal command (see here )
I now did two things trying to fix it as described this post on XDA developers.
- I tried to re-flash two files from the latest Android 9 SONY stock rom via newflasher (amss_fs_1_X-FLASH-ALL-C93B.sin and amss_fs_2_X-FLASH-ALL-C93B.sin). Unfortunately, IMS features did still not work and I also did not see the list of available modems in Settings → Xperia Parts → Modem Switcher Activity
- I then upgraded to the latest IodeOS 5.11 with dirty flashing (Using TWRP recovery, wiping Dalvik Cache and Cache and then using ADB Sideload)
- I then played around with Settings → Xperia Parts → Modem Switcher Activity: first I deactivated IMS Features, rebooted and then I activated it again and the phone said it will reboot to set the IMS Features for my carrier
IMS features now work again: I can do VoLTE / VoWIFI calls and I see the list of available modems in Settings → Xperia Parts → Modem Switcher Activity.
I do not know whether both steps were necessary to fix it again or whether IMS features were simply broken at the IodeOS 5.10 release. But maybe my post helps someone.
I also had this problem and appear to have solved at least the missing-modem-config part. After doing that, though, I still don’t have access to the VoLTE/VoWIFI options I used to. Could you attach screenshots showing where you have access to these?
(I see VoLTE and “WiFi Calling” in the Settings search results, but tapping either leads to the settings for my network provider and these settings are just not shown there.)
Hm, now I see that the MBN for my provider doesn’t appear to enable IMS.
This is how it looks for me. Settings → Xperia Parts → Status
VoLTE/VoWIFI is working.
Before I made the fix, there was only the default modem active and I also could not see others modems to switch to in “Modem Switcher Activity”. I noticed it was not working properly, because the phone always fell back to 2G for calls.
I’ve updated to 5.12 yesterday, everything seems to work well. Thanks a lot

Where you found that? I checked two links but ROMs are no longer there.
IodéOS builds for this device can be found at https://download.lineage.microg.org/IodeOS/lilac/
