SIM cards not recognized - Xiaomi Mi A1 Questions & Answers

I have Android 8. Blokada & Magisk(with Mi A1 Camera Lag Fix Oreo module) are installed. And after rebooting my phone I get often a notification that my SIM cards were not recognized. I must reboot the phone again and then it works properly. Any idea what's wrong?

Sudden WLAN failure

Hi,
Phone was doing great and overall it was really awesome experience. Suddenly I noticed I cannot turn wifi on. After restart phone started to bootloop, reflashed system, restored twrp 4 days old backup - nothing worked. I wiped everything even sd card, still bootloop. Sim cards seems to work but only in 2g.
Board check says SD and WLAN fail, device status says WIFI mac address is unavailable.
Guys, any ideas how to fix it or is it hardware issue?

Use aosp extended, best rom for yu users.
Get it from official site. Try to get root access from developer options. If not working any method then use another file manager ( Asus file manager).

Try another method to connect in fastboot mode.
Remove battery
Connect data cable with PC
Now press and hold volume + key
Connect data cable with phone
When phone go-to fastboot
Immediately remove finger from volume key
You can do it be positive and try again and again.
When connected then find right firmware for your phone on www.androidfilehost.com or Google it

Big Issue with lenovo K6 note

hello everybody there,
well i'm facing a very big issue with my Lenovo k6 note (k53a48), for example, when i try to make updates to my apps or install new ones via play store, i starts the download normally, but when screen is off, it doesn't install the app that was downloading and also doesn't go to download next app in queue untill i go again to play store. also messages apps like what's up and viber messages don't show when screen is off until i go to the app and open it,
i tried a multiple Stock ROMs, i have that problem in marshmallow and nougat also, i did factory reset, the same issue persists
checked also options like : apps always on in background is checked for all the apps, also wifi always on. also phone is not in battery economy mode.
so i don't know from where it comes this problem, please help me

backup all of your data,format data,system,cache and dalvik, i think it is encryption problem. How did you install the stock roms? Via QFIL or...?

Install ADB & required drivers on your pc.
Turn on usb debugging from developer options on your K6 note.
Connect your phone to pc and open ADB.
Type the following commands-
fastboot reboot

fastboot erase cache
fastboot reboot

I don't know which ROM you are trying to flash but if nothing is wrong with ROM itself then you can try using Qfil to flash ROM on your K6 note.
(I personally used Qfil for flashing ROM on my K53a48)

are you sure this will solve the problem. im facing the problem for one year.. now I'm using a single sim for ignoring the problem.
I've flashed a number custom roms and stock roms after that my device doesn't recognise dual sim.. if i insert two sim card at same time..then the device will choose one sim card . only that one will work.. my two slots are working because i checked inserting a single sim card at each sim slots. but if i insert two sim cards either of one will work.. so i goto lenovos service centre but they cant fix the problem. so i started to use single sim card.
my device is also k53a48
if i use the above command is it will cause further error..??
are u sure that this will solve the problem

Yes, it should definitely work.
Even I had the same issue few months ago and searched a lot for solution. Finally on Lenovo's official website a person posted this solution.
I have flashed ROM multiple times on my device and faced this sim issue almost all the times.
I actually discovered this solution while I was searching for "Network band switched to US" issue. Used it when I personally faced this dual SIM card issue and it worked.
Reply if this helps you too

a3 2016 overheating warning when SIM installed

hi,
overheating warning appears on the screen although the phone is not hot. the phone doesn't charge the battery... this situation only happens when the memory card and the SIM inserted in the phone. no cards installed, no warning; everything is OK, the phone is charging, all functions are working without a problem..
i try different stock roms on Marshmallow and Nougat, it did not help.
any idea? thanks..
