Fingerprint issue on A12 - LG G8X ThinQ Questions & Answers

I was originally on 850UM A10 sprint(network unlocked), I've crossflashed it to open_ca, everything works fine, except for the fingerprint, I do have my bootloader locked, it is not rooted,etc.. Do i have to downgrade it to A10 again to get the fingerprint working again? As far as I know, sprint doesn't push updates through OTA anymore, so no chance upgrading it to A11 nor A12. Anyone had similar problem as mine?

MOTO Z Network issue even after flashing Stock Firmware

hi,
I dont know why i having this network issue.
I flashed lineage os8.1 on my phone and my sim isn't getting any signals. Yep o tried to wait for more than 2 hours, yep i tried different locations, yep my sim is working on other devices, yep i tried to put a different sim but all that didn't work. Mind you my wifi, gps, Bluetooth etc all are working. I tried to flash modem 1 and 2 with non-hlos etc but that didn't work either. So decided to flash stock firmware. Mind you i was on December security patch 2017, meaning having bootloader version 91.08. But since indian firmware flash file is 6.0.1, it won't be compatible, as the bootloader version cant be downgraded. So to get stock firmware back and running i decided to flash RETUS retail version. That firmware did have bootloader v91.08. But unfortunately, I'm getting bootloader remote failure errors, and phone gets into a bootloop. Then i decided to flash RETCN firmware. That did work, my phone is up and running but then again that my sim isn't showing ant signals. I tried with different sims. and dont know what to do.
Oh and one more thing, my imei is visible.
Please help me with this weird sim signal issue.

Definitely you have flashed other region firmware with its own NON-HLOS.bi. so the solution is this that you have to flashed your own region firmware according to your bootloader version.

Yes my brother I also having the same problem. My device is also retin and I also had flash the same retus firmware in my device. Because there is no firmware available for India. The thing is go to the authorised Moto service centre and asked them to update your phone. Do not say about baseband ,even if you say they are going to do but they don't know what is baseband, so they will deny that bootloader is unlocked. Or wait for the Oreo update. It will fix up everything because it comes with everything updated. Only and only if you have retin software channel. But by the way can you tell me your baseband version."it is important to know for me and for you". You can check it out by seeing in about phone.

The only thing which will work here is FLASH ANY CUSTOM ROM because no one can fix your problem. Not even Motorola.
And you will be surprised that I am the only one who solved this problem with stock rom. And dude it took a whole month.

Question about firmware update on rebranded phone

So I've successfully rebranded a Chinese Honor9 (STF-AL10) to the European branding (STF-L09C432). Next step is install a L09 firmware. But there are 2 problems on the phone, which I believe are very common:
1 - no capacitive buttons
2 - camera flash/torch not consistently working
Is there a known firmware that I can flash to fix these problems (especially the camera flash problem) ? I read the B120 firmware is the way to go, but I haven't seen any download links (including pro-teammt.ru) that work. I know that flashing the lastest ROM will make downgrades brick the phone (this has already happened to me, but I was lucky enough to get another replace AL10).
Thanks.

Hello, I have also already rebranded Honor 9 from stf-al10 to European L09. I know the best way to rebrand it. You are supposed to unlock the bootloader at first and then root it whith open kirin twrp. After that you should change the oeminfo to L09, its really important. In that way, you can rebrand to L09 without problem. Do not forget to save the stock al10 oeminfo.

[SOLVED] In need of help with RMX1921EX_11_C.02 version bugs

Hey guys, i've come across some bugs while installing the RMX1921EX_11_C.02 version from the Indian site to my phone and i would like some clarifications or help if someone faced those and overcame them.
- To begin with let me start by saying that I bought a global Realme XT with the firmware being RMX1921EX_11_A.05.
- I then managed to brick cyclops the device by trying to install RMX1921EX_11_A.10. Phone wouldn't boot, stuck on the Realme black/white logo.
- I managed to install RMX1921EX_11_A.06 through recovery and sd card.
- Then I downloaded from the Indian support site and installed through file manager the version RMX1921EX_11_C.02.
Now, on this version everything seems to work ok minus some bugs:
- Phone gets a bit laggy sometimes
- Brightness in automatic mode is not working
- Software update through settings won't work. Crashes a while after opening
- Battery life seems affected, won't last anyway near to what it was on RMX1921EX_11_A.05
So my question is, has anyone experienced any of those and found a solution to the bugs?
Also, is there anyway to obtain and roll back to the original stock rom RMX1921EX_11_A.05 from the beginning and then wait for the official OTA update?
Thank you in advance
Are you sure your phone firmware is RMX1921EX_11_A.05. (India version) not RMX1921EUEX (global version)?
If your firmware is India version, you should be able to unlock the bootloader and install twrp.

Yes, absolutely sure but im confused as RMX1921EX_11_A.05. is supposed to India version which my phone had but then the place i bought it was advertised as the global version and also i didn't receive the official ota update through the phone's update settings (and supposedly having the indian version). Seriously, realme's firmware naming and distribution is so confusing and impractical. but let's say i indee have the indian version, what does unlocking the bootloader and installing twrp mean? how will that help me and are there any cons into doing that? Thanks man
unlock the bootloader you can root the phone
https://forum.xda-developers.com/re...ecovery-unofficial-twrp-realme-5-pro-t3985459
My XT is was some as the global version. But from what I'm reading this says I'm using the Indian version? But I have NFC. This is so confusing. Bought this phone thinking I could unlock and root.
This confusing but normal. I bought two EU phones with NFC. One for me and one for my girlfriend. She is still on RMX1921EX_11_A.05.
I updatet my Phone to A.06 and when i look in phonedetails is called RMX1921EX_11_A.06.
I read that A.05 can be unlocked in the other thread. I would test this by myself, but yeah i don't want drama with my girlsfriends phone.
So i don't touch it

India version comes with no NFC. You can try Depth test apk , it won't hurt your phone even you pass it. Let us know if your global version can pass it or not.

Flashing went smooth , phone booted up everything was working fine except there was no network. Now can anyone help me with a guide how to solve this issue if there is a solution?

General Convert Moto x40 (CN) to Motorola Edge 40 Pro (EU)

Hi,
after question on lenovo forum, here is my installation guide.
Warning:
I dont know what happen if you relock the bootloader after flashing, so dont relock it.
There will be no OTA updates, software update chanel is still retcn.
Every part of this instruction is done at your own risk!
Pro:
5G is now working for me in Germany
Multi-language
Requirements:
Unlocked Bootloader
PC with ADB and Fastboot Tool and Motorola ADB Driver
Download ROM: https://androidfilehost.com/?fid=4279422670115730514
Download flashfile (you can skip this and do it manuelly): https://1fichier.com/?zd9n4g4vj0gf59577w64
Install:
Download ROM and flashfile and extract both in one folder
Unlock Bootloader
Boot phone in Bootloader (power off phone and start with power on + volume down)
run flashfile.bat
Any cons? Any bugs you're experiencing?
Also are you able to pass safety net with magisk? How can you later update the software if ota is not possible?
Much appreciate the description
You can change retcn to reteu
command there: fastboot oem config carrier reteu
After relocking the bootloader the safety net will pass?? Could please send a snapshot of the safety net status after flashing?

Have you sold already the X40? If 5G works on X40 , which one do you recommend? Oneplus11 or Motor x40? I have a same concern to loosing the safety net pass, and far as I know, the Edge 40 pro has 1-NanoSIM and 1-eSIM I am afraid to loosing the second SIM...

In my opinion Moto edge 40 pro is far better than op11 which I have now. But unfortunately I only paid 600£ for the global op11 and Moto is 800£, as the don't give any discounts. X40 is on AliExpress tho for 480£ so I might sell my op 11 and buy x40 and install global Rom, if there aren't any issues

Currently I am using X40. I am little bit afraid to unlock the bootloader but I will do it soon because I need 5G but also need bank apps to be running. I will let you know about the results. Based on another forums feedback with the relocked bootloader will solve safety net issue.. let's try

I use it in UK and Poland. Bank apps work fine in both countries.
I didn't test 5g. Living in small village. x40 Chinese room.
great was thinking of getting the Moto x40 from AliExpress as it's far much cheaper than the global Edge 40 Pro
Does anyone know the difference between T1TR33.43-20-5 and T1TR33.43-20-15 firmware? A security patch maybe? I have now installed version .43-20-5 on my X40. Rooted with Magisk and safetynet passed. Can I just flash the newer version .43-20-15 via fastboot without losing data? Thank you for the effort.

Few questions after flashing EU FW and with bootloader unlocked:
Is fingerprint scanner working?
Is gps working?
Is wifi working?
OTA Updates are working with unlocked bootloader?
Does something change after bootloader re-lock?

Everything is working fine. OTA updates haven't arrived yet so I can't say if it's working.

Even after relocking bootloader it is not working.
Do you know when/how I can enable OEM unlocking? Now it is grayed out (after relocking).

Hey fellas,
I successfully flashed from CN to EU and locked the bootloader after. Safetynet is failed and i want to return to the stock ROM but the OEM unlock is greyed out for me. Do I have to wait till i can activate it again?

you might need to use the moto rescue and smart assistant toll to go back to original firmware
The flashing went well. At first there seemed to be no problems for me. Wifi, GPS, fingerprint etc all are working. But in the night the phone soft reboots every ~30min, which leads to 40-50% battery drop during the night.
Clean install doesn't help.
Waking the device every 15min seems to prevent reboots. First such test consumed 30% of battery during the night but I have to test it a bit more.
I tried flashing back the CN rom (2 releases), but now locksreen pattern/pin/password can't be set (the app freezes and then crashes).
Also the phone is not on the list of rescue software.
