Indeed a decrypt issue.

Since you are using TWRP, did you upgrade your TWRP to one that can decrypt A12? Are you using DFE decryption? Many things can go qrong here.

Indeed the addon.d issue is telling... Can you see your files on internal memory from twrp? I would upgrade TWRP or use LineageOS recovery and then try flash again.

You might be out of luck anyway and need a full clean flash at this point.

But indeed upgrade to latest available TWRP or use Lineage recovery.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] poltak11:
Thanks for your reply! I'm using TWRP 3.5.0 by mahajant99, which claims description works, though unclear whether it supports A12 or whether I'm using DFE decryption. I haven't done much android device tinkering in years. Files in /sdcard are definitely encrypted in TWRP - names are all obfuscated.

Let me know if I'm using a recovery that doesn't support LOS. Else I'll try Lineage recovery or, if I've messed something up earlier with the decryption, I'll do a clean flash.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Get this twrp Here

I guess at this point you must cleab flash. Dont use dfe anymore.

twrp you have is ancient at this time, update, and Its clearly the cause of your issues.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] helcaraxë:
@gardiol I have a problem (bug?) with the notification sound level.

I have the ringtone volume at 0 (3rd setting in "audio"), and when my phone starts, the notification volume level (5th setting) is always 0. If I change it, it reverts to 0 when I go back to the settings page or reboot the phone.

If however I set the ringtone volume to any value > 0 then it lets me change the notification volume.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Maybe you linked them. Check in settings
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] helcaraxë:
They're not linked. Can somebody try to set their volume level for "ringtones and notifications" to 0 and then try to change the notification level below?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] poltak11:
Thanks for your help. I've done a clean flash of LOS with that recovery and things seem to be better now. Now, each time I reboot into recovery, I get prompted for my unlock code and it successfully decrypts /sdcard.

As a casual phone tinkerer, I didn't realize my TWRP was so old. It was the main one that had its own thread here on XDA. Maybe it would be good to link the newer TWRP required for LOS in the OP here?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
TWRP is not recomended, i only recomend LineageOS recovery and i don't whish to link to unofficial builds from Telegram too much, so i will not link it to OP.

Unfortunately XDA is pretty much dead for Surya, and it has been for quite a long time. Everything goes on on Telegram and that sucks. I try to keep this thread alive as much as i can because i am an old-timer and i think that XDA, while far from perfect, is better than a "chat" app for these things. But indeed its a fact that most stuff only goes on there and only there you can find updated stuff.

On the TG support group there is a lot of daily traffic, while here maybe one or two posts per day, but less than a dozen every two weeks. Also most of the other threads suffer the same faith. I do my best to reply here, but the limit to post TG links and the difficulty in uploading files directly (and i don't like to add another different external storage for the same files) makes difficult sometimes.

What would be needed is a safe long-time storage for files and builds linked with a good XDA style forums board website. Sadly, both XDA and TG lacks either one of them.

Is it just me or is there a general issue with the dial tone? Whenever I dial a number it just says "dialing" after hitting the call button. There is no dial tone any more (used to be there on Android 11).

As soon as the other end picks up the phone the sound is working properly, so this is just a minor bug. It's still a bug I think or are dial tones working for you guys?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Never had any such issue
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] _geoZ_:
I had the same issue. Turning off 4G calls fixed it.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Vavun:
Hi.

Are there any plans to make experimental builds of LineageOS 20 for those who want to help with testing?

To be sure that the device tree will be ready for the official LineageOS 20 official release.

I,m not asking for ETA, just curious.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Yes. But wont do anything until los 20 is at least semi-stable.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] daniperez_97:
¿Is this worth it and stable enough to change from arrowos A11?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
I have no idea how to reply to this.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Stable yes -- running it rn, coming straight from A10 (RROS). Worth it? YMMV...

PS: just be sure to flash an alternative kernel -- like the latest SiLonT or StormBreaker.

Talking of which, anyone tried TheStretchh's QuickSilver kernel yet?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:
I suppose this is done via recovery? Is it possible with original LOS recovery?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Flixnet:
That worked for me for some weeks only. Now it's too "unsafe" again to pay with.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] daniperez_97:
When trying to install the OTA update, it brings me to recovery, but it doesn't ask me for password and the data is encrypted

Pm me on telegram
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] _exian_:
Same here. I also "fixed" it by setting the ringtone volume to a non-zero value, even though I'd rather have the vibration only.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Yes and, while I assume it's possible, I have no idea (never tried...).
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] sturges:
Yes, just flash the kernels zip in LOS recovery. I tried Stormbreaker which had worse battery so went back to default. I've heard with SiLonT the phone is a bit hotter (couple degrees) but should work better.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:
Thanks, just flashed SilonT via recovery, no issues so far. I'd always prefer stock kernel aswell but it gave me too much freezes.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Pan_Nekdo:
The freezes are really annoying so I'd try this kernel as well but I've never flashed kernel, so any instructions?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Just flash kernel zip from recovery.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Klaerchen:
What freezes? I did not observe any so far.

At what incidents?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
It really depends on hardware. Somebody has Somebody dont. Installing a custom kernel fixes it Anyway
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] jackho2020:
I've the same issue. There is no dial tone after hitting the dial button. No idea how I can fix it.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] jackho2020:
My phone freezes several times a day. Will try other kernels to see if it can be fixed.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] sturges:
Never had this issue with any LOS version. Are you sure you're using the correct firmware?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] jackho2020:
After trial and error, I found that disabling volte solves the issue. However, I need volte to improve call quality.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:
Mine is running rock solid now with SilonT kernel. Really an awesome phone now, thanks to everybody who helped bringing Lineage to this device!
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Klaerchen:
What's the difference between the standard kernel and SilonT's?

Wouldn't it make sense, to have the relevant modifications also in the official kernel, to make it likewise freeze-free?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Pan_Nekdo:
I had the same problems as you have and flashing new kernel has fixed it (not a single freeze since then). I just dirty-flashed the newest SiLonT kernel (Richelieu) and that's all.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] minax007:
I have the same issue with this ROM on one of my devices and would like to fix it.

Where did you get the newest SiLonT kernel (Richelieu) from?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] minax007:
Hi @gardiol

do you know the root cause of the freezes?

I saw that you wrote that it is hardware related.

But isn't it possible to fix this issue via software?

How likely is it to get the freeze issue in a later release fixed without having the need of flashing a third party kernel?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Pan_Nekdo:

[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] minax007:

The freezing issue seems to be resolved in the latest LOS update.

Sounds promising, I'll give it a try.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:
Still crashes on me unfortunately. Back to SilonT...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:
Similar crash with SilonT kernel today. So maybe it's not really a kernel issue? Now trying 26-09 nightly with LOS kernel...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:

yeah, its running very well
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] haupauge:
mine has also no dial tone on outgoing calls. i tried to disable LTE but with no luck. could somebody give me an advice?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Nexonian:
What exactly did you disable? You need to disable phone calls via LTE (VoltE), not LTE in general. This can be found in the SIM card settings.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Mobe1969:
I'm struggling to get gcam to work. In the instructions it tells you to copy the XML file somewhere, but it is unclear. Eg "under some folder like "gcam/config7". And it says "double-tap on the black area on the bottom of the screen." Is this in some app? Somewhere in the launch bar? I personally don't have some black area at the bottom of my screen. I mean I thought it was referring to gcam itself, but when I open gcam it just crashes. No mater what build I download form that gdrive folder

Can anyone help? I don't use gapps - I suspect this might be related.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] RobSouthern:
October 10 update has almost completely fixed freezing for me. I get occasional pauses for 10 seconds, but they are very rare, nothing like before (total freeze and hard reset required)
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
GCams don't work without gapps i am afraid.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:

I have gcam working with microg installed - GCam_7.3.018_Urnyx05-v2.2-fix. Config can only be loaded within gcam and double tap on the black areas near the shutter button is what you need to do to load.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Mobe1969:
OK so it needs other stuff to work, it won't work with straight lineage
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] gardiol:
Either gapps or microg is required.

After having last checked in August, I'm now just about to convert the first of our POCO X3 NFC (surya) from ArrowOS 11 to LOS for microG 19.1, so what's up with

Firmware: The instructions say "12.5.7.0 (anything newer will work)" and the latest stable for Europe is V13.0.2.0.SJGEUXM. So can that one be used or is another version recommended?

Kernel: In August it was all about the StormBreaker kernel. What's the recommendation now? Still StormBreaker, SiLonT (though the latest release for these two is from July), QuickSilveR (latest release from 1st October) or stock?

Recovery: LOS Recovery still good enough or any TWRP recommendation?

GCam: Recommendation for which version and config from the provided link?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] LOLcorpse:
use 12.5.8 MI FW

Kernel Quicksilver or DEXK - based on QS (SB and silont has bad battery backup and worse than stock los kernel imho)

TWRP 3.7.0 FBE v2 by Brigudav

Gcam LMC is best
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] sturges:
Depends on whether you need the extra features in twrp or not. LOS recovery works without a hitch for me (btw I use stock kernel and don't have any issue)
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Master One:
Two annoyances/bugs connected to dual-SIM use so far:

Aeroplane mode makes phone forget SIM configuration, so every time (and I use Aeroplane mode several times a day) I switch off Aeroplane mode the pop-up "Select a SIM for data" comes up and the settings for "Calls and SMS" are gone (reverts to "Ask every time" for both).

There is no possibility to configure two different ringtones for the two SIMs.

Nobody else here using two SIM cards?
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
I am. Didn't observe any of this. Which build are you on? I'm on 20220905 (tried 20221017 briefly but had to revert back due to lack of SIM connection)...
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Master One:
I tried with

LOS 19.1 for microG 20221014

LOS 19.1 20221017

but the same problem with both of them (fresh installations after factory reset with nothing else configured or installed).

I can easily reproduce that problem, because it comes up every time:

Boot a fresh new installation.

Go through the install wizard and configure WiFi.

At the end WiFi and both SIMs are active.

SIM1 configured for data and default for SMS.

Activate Airplane mode, wait a little, disabling Airplane mode.

The "Select a SIM for data" pop-up comes up and the configuration for default SIM for SMS reverted to "Ask every time".

This is cumbersome to deal with, because as said, I'm using Airplane mode several times a day. Not sure what to do now.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] Yoda007:
This happens to me as well in the latest build (previous builds were OK). Sometimes i get the PIN message, and the SIMS were changed message without turning on the Airplane mode. Hope this is fixed soon since i allways put the phone in airplane mode every night before i go to sleep.
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] pnin:
Just re-tested: can do Airplane Mode fine, phone is a little sluggish coming out of it -- had to re-enable WiFi manually -- otherwise everything looks OK...

FYI, LOS 20220905 as stated before with DEKX 4.14.295 (released 20221003).
[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] krzysiekx:
Dear all,

tl;dr

Should I sideload adb or zip flash TWRP in order to install lineageos on Surya with unlocked bootloader? Do I need one zip only, no vendor or stuff?

Could you give me a little hand as to how I should go about installing LOS and TWRP for the first time?

I just managed to unlock bootloader on my Surya device.

So after installing twrp.img via 'fastboot flash recovery' and 'fastboot boot recovery', is it enough just to install the lineage-19.1-20221024-nightly-surya-signed.zip zip?

I am asking, because on the official LOS website it says something like this (here's a part of the official guide):

'Installing LineageOS from recovery

Download the LineageOS installation package that you would like to install or build the package yourself.

(Optionally): If you want to install an application package add-on such as Google Apps (use the arm64 architecture), please read and follow the instructions on Google Apps page

If you are not in recovery, reboot into recovery:

With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.

Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).

Return to the main menu.

Sideload the LineageOS .zip package:

On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.

On the host machine, sideload the package using: adb sideload filename.zip.'

So after I manage to put TWRP (version 3.5 from xda, I believe) on my phone, will it be enough just to wipe and install from zip instead of sideloading mentioned In the guide before?

Asking, because last time I did it Flashing a zip was enough.

Also, i have miui 13 android 12 stable Eea ROM and unlocked bootloader.

[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] kradNZ:
Wifes phone has been running Lineage for some time now without incident. Tonight with battery <10% screen turned off randomly. No powering off screen, just suddenly died.

When attempting to reboot ph gets stuck on the 'Poco' screen.

Entering recovery mode (twrp 3.5.x) just hangs too. It remains stuck on the twrp splash screen.

I've tried newer versions of twrp (twrp-3.7.0_12-0-surya-29.09-fbev2.img) and it too gets stuck on the twrp splash screen.

Anyone run into this before? Its weird. Possibly hardware failure or am I getting ahead of myself? Don't really want to have to reset etc.

I tried clearing dalvik cache via fastboot erase cache, but it still won't boot lineage.

Edit: Also tried lineage recovery.

I assume fastboot boot twrp-xxx.img is valid and I don't have to flash it directly?

Freezes are gone from official builds. On Telegram i am also sharing LOS 20 test builds, which are damn pretty stable so far. Anyway, freezes where caused by LMKD which _requires_ zram to be enabled to properly work fine. So i have enabled zarm back in stock kernel and all is fine.

Other kernels did work because they included an "old" LMK implementation which takes priority on LMKD and works without zram. But since LMK is pdeprecated and LMKD is the future anyway, zram is back and we are all the better.

Hi everyone,

Hopefully someone can help me. It's been a while since I flashed custom roms, but got my x3 nfc stolen during vacation and now bought a used one back that has fresh install of Lineage 19.1 (19-20221031-NIGHTLY-surya) on it.

Thing is, it doesn't offer me the typical Google restore data/settings/apps option when setting it up.

I tried a factory reset, but that rebooted into recovery -> Mount -> Decrypt Data and asked me for a password i'm not aware of (TRWP 3.6.2_11-0-surya).

The recovery has so many options and settings I'd rather not mess about with it.

Any tips on getting a google backup installed on this phone? Or (re-)flashing the rom if need be? The stock MiUI rom would be acceptable for me as well if thats easier to accomplish.

Tia,

Marc
