Kernel crash : modem crash - LG V20 Questions & Answers

Hi all
I had already successfully flashed lineage OS 15.1 and 14.1, but since I had a problem with my IMEI, a kernel crash occurs 3 seconds after booting: Modem crash.
The thing is I have to stay on Lineage OS 15 if I want to keep my imei because if I go on stock-based ROMs, my IMEI becomes 0 and these ROMs do not accept xposed... In addition, I already tried to flash another modem. img or a custom kernel...
Any ideas ?

wow, so apparently i'm not alone.
H910 here, exact same crashing seconds after booting almost everytime. if im lucky i'll able to pass the unlock screen and my phone is working just fine. but most of the time the phone just won't let me
i dunno how to grab a proper kernel dump, but here's a pic of the kernel crash if that helps https://imgur.com/a/5Zy7tZN
oh, it crashes with LOS 14 / 15.1 builds only, works fine on stock.

You guys need to take this to the lineage threads to get assistance

Random reboots on every custom rom

Hello!
Every custom rom I try to use in my redmi 2 pro 2014819 (prime in USA, pro in Brazil) shows random restarts, usually when the screen is off.
I have tried to use different bootloaders (miui KK and miui LP), different versions of TWRP (2.8.7.2 and 3.0.2.0), remove the sd card, different ways to flash, change the Linux from permissive to enforcing, disable the kernel panic , Different roms (the only one that did not restart in 4 days was CrDroid 4.4.4); And all led to random restarts.
I have already tested RR mm, RR N, Cyanogenmod, LineageOS, TeslaN, Tesla MM, AOSP Extended, Dirty Unicorns, AOSIP, Mokee 6, Mokee 7.1, among others, and unfortunately all presented the same problem.
I would be very grateful if anyone could help me; I believe that the problem is not in the process of flashing, but everything is possible.
Thanks in advance!

I tried to flash, but reboots continued to occur; The only change that occurred was that I could not get into twrp anymore, I will restore via fastboot and reinstall. Not put in the roms thread as it happens with all, and I believe it to be some problem on the device chip, twrp or something.
You should try the Jerrica Cosmos Kernel on RR or Mokee Rom.

S3 Neo (I9300I) Bootloops randomly

Hi guys! my s3 neo started randomly bootlooping after 1 year, I had RR 5.5.9 on it. I noticed that if I press button_vol_up when bootlooping the phone starts to access recovery, but suddenly continue rebooting so I tried to wipe ALL in the s3 neo from TWRP and with Odin I reflashed a new version of TWRP. After that, I clean installed the RR 5.5.9 and for a few days started working good.
Yesterday night the problem seems reappeared and then I soldered a new power button thinking it was the problem ( even if it's a random problem, it seems) but without fixing this problem. So I decided to desolder the power_button and starting using without it, and the phone was working very good, after 6 hours booom! the bootlooping is still here.
Can anyone help me? Thanks in Advance
When your RR is based on CM12.1 then the bootloop occurs when you install some new updated apps. You have 3 choices.
1) avoid these apps
2) Inform the developer of the apps, that with the new update your cm12.1 version gets a bootloop. The bootloop occurs, when the updated Version of the app was build with the new android build tools. The Solution is to use aapt instead of aapt2
3) upgrade to cm13 or cm14.1 . Theres also a RR based on 14.1. I didn't try this version, but i think with this rom you will not have the bootloop
same problem.
I have tried to flash it with many firmware without any success.
any help

What exactly is your problem?
Meanwhile there are quite stable Custom Roms that would be there:
- CM 12.1 from December 2017 (no more bootloops!)
- LOS 14.1 from August or also December 2018
- crDroid from November 2018

It it solved my voLTE works now
Having a serious problem.....I'm running pixel experience ROM now but I have a tried nitrogen OS, ressurection remix ROM, Lineage OS 15.1, Viper OS (nougat), Lineage OS 14.1 and many other ROMs. Volte was working fine few days ago but for the past 3-4 days it was not working. I thought it was a problem with the ROM so I changed the ROM but still got the issue. And today I came to know that my device is showing IMS registration: unavailable
Voice-over LTE: not available and some other things
I tried messing with APNs and flashed some volte patches but still got no luck. Then I tried searching on XDA forum and know what I tried every possible method in almost all the threads and still not able to get volte. Tried searching YouTube for IMS registration and tried googling it also but still the problem is there.
Help me out plzzzz....

Maybe you need to write IMEI number again?
Does it show there when pressing *#06#* ?
U may try going back to MIUI 9
And then back to your favorite ROM
I did every single step mentioned above. Even my IMEI number is all good. But VOLTE problem reamins the same.
During the first boot...VOLTE was there, and it was working. Even when I Rebooted, it was again there and still working. But when I Power Off the device and then powered it on, VOLTE was gone and I was unable to call.

I did that too and thrice bt the problem remained unsolved. As I mentioned, it worked during the initial boot of any custom rom, even after rebooting it. Bt when I powered it off and then booted it up, VOLTE was gone.

Yeah happens with me to but now m using Xiaomi.eu miui 9 ROM bro use it for some days and flash another ROM voLTE will work fine as it creates a strong bond between firmware and ROM that miui 9 official doesn't and it has more features than it miui 9. So give it a try

Will Jio work?
Use this trick:-
Flash any miui rom v8 or v9 & boot into system..
Now go to recovery wipe all except storage.
Now flash any custom rom i suggest lineage 14.1 & boot into system..
Now again go to recovery go to wipe , advance wipe & wipe only system
Now flash any MIUI rom then wipe cache & dalvik
Now reboot...
Volla your volte now works...
I tried 2 times & all time it works....
If it works for u hit thanks..

Bugs Lineage 18.1.

[email protected] all
I have a Samsung G900F
I had an old lineage version (don't know which). Now I flashed the latest TWRP and Lineage 18.1.
But it doesn't look at all how it should look. There is some very strong flickering and also some other weird stuff going on
I flashed the stock rom and then flashed lineage again, but it's still the same.
Can someone tell me what to do next?
thanks <3
edit: I think it could be the app 'flip flap'. I read in another forum about it.
there are more then 1000 notifications in a few minutes, I think it's not normal. But when I try to deactivate it it doesn't work.
