[Q] Constant FC over com.android.phone after CM6 or MIUI

Hello,
I need some help with my Milestone ( Cellcom Israel ).
After installing any custom ROM on milestone: CM6 (before the 6.1 & 6.1), MIUI or the FroyoMod whenever the phone stats it will:
FC every 2-5 seconds over com.android.phone (each time changing the signal to an bar + X on top of it ) and have no Signal (no network found).
I cannot go into mobile networks options (as each FC closes it automatically).
G.O.T 2.2.1 is running perfectly fine with no changes after install (installed the Italy Wind Rom).
Tried to change the Band from the OR to both the italy one + cellcom's (ISRAEL, which is my provided) but nothing helped.
I did manage to get it to work once (after removing the SIM, choosing Italy band, restarting and... i think thats it) but after another restart it got broken again.
I found a topic on this, stating that it might be a SIM problem and that replacing it will fix it, but its not much of an option (as there is nothing wrong with it to the provided).
Does anyone has a clue?
Thank you for your help,
Alon

My device has problems just like your MS, I asked this issue throughout the topic, but still do not have the correct answers.
someone said that the error was due to sim, change the sim will solve the problem but I think something was at fault in the development process. eg FroyoModv1. EclairMod, Ho! No! Froyomod, there are not errors. But MIUI, CM6.0, Sense .. phone.apk crash again.
hope someone will find out this error and help us.

try to do a full whipe clear everything and go back to your stock ROM, flash your version/region SBF with RSDlite from http://and-developers.com/sbf
and replace Simcard as stated

Well, i will try replacing the SIM, but im not sure that the provider will just approve of that.
I mean come'on, i can't tell them it doesnt work on CM6
as for the whole wipe, ammm, maybe ill try it later on today, in order to install CM6, i must install the GOT2.2.1 first ?

haha, just tell your provider that your sim has been lost and get another one.
I will do it in spare time .

Well this is weird.
Reinstalled MIUI, same problem
turned on and off airplane mode 10 times (while trying to fix), moved to 2g and other **** in the mobile network options, NADA.
Restarted, reinstalled ITALY BAND.
restart, everything ok.
had my fun with MIUI.
restart, bad again.
repeating the process of installing the italy band doesn't help anymore.

if you want totry, I'll tell you my experiences.
flash rom and switch on airplane mode, then restart. when the operating system booted, turn off airplane mode and everything is back to normal until you restart it again.

Click to expand...
Click to collapse
hmmm, that makes sense.
I probably left it on when I was experimenting with the airplane mode I'll give it a try later on ,damn this is annoying!
So this is probably a rom issue... I wonder why the sim card change fixes it.

No SIM signal or wi-fi after update

Hi everyone,
I have a big issue with the xiaomi.eu Miui 12 20.7.2 and other after this...
After install in my phone (Mi 8) I dont have access sim card. Is like that I dont have any sim card. And no wifi to.
I've done first a dirty install and after a clean install but the problem continued.
After I was rollback to the 20.6.18 version where all works fine! if I upgrade again the problem still the same...
What can I do?
Thanks

Same issue
Hi, I have the same issue, in my case that issue started once I installed Miui 12 20.07.16. I tried installing other ROMs without fix this problem, I will wait until they deliver a new version waiting they solve this problem.

Which TWRP did you use to flash the rom?

I don't think it is a software problem if you have the following symptoms, No WiFi but Bluetooth, no service but detect SIM card, random reboots out of nowhere or when trying to turn on WiFi, unknown baseband and it gets hot, apparently it is a processor SoC solder problem

Sim not activating

Hi guys! Randomly my mi 9 stopped recognizing the sim card. When the sim card is inserted there is also no wifi, when you remove it the wifi can be turned on. Have tried everything, hard reset and then Android setup not working also!!! After rebooting several times, sim in , out, in and out, different sims, rewiping data, nothing seems to work. Back to stock MIUI 11 not working. Updating to the latest 12.0.4 also not. Any ideas? Living in the US with zero support, so any help would be great. Thank s in advance!

APN type correct?
Try the following
default,supl,dun

Question Brand New Redmi note 10 Pro keeps on rebooting

I just bought a brand new redmi note 10 pro 6gb 128gb and on the day of delivery the device keeps on rebooting. There was an update pending and updated to the latest miui version and the problem still persists. It was booting randomly before updating but after updating it just keeps on rebooting. Is there any fix to this or do I need to return this?

Maybe there was something wrong with the update, try factory reset from recovery, or if that doesnt help try flashing latest firmware via fastboot.

So I found a recent development in this. Apparently it only reboots when either the wifi or the mobile network is on.
So I have airplane mode turned off n I have removed the sim card as well and now the phone is not rebooting. But as soon as I click on wifi, it reboots.
I can't factory reset it because I activated Duo mobile in it n to reactivate I need to contact my company. It's a hassle

GOOD DAY NEED HELP PLEASE

Good Day and Peace and Blessings to everyone here.
My problem is that my daughter's phone (Redmi Note 9) has been giving trouble with recognising the dual sim and memory card tray, this happened some time after purchase and it's first update to MIUI 12. Normally this would happen when the phone was restarted, the tray would have to be popped out and re-inserted and then the tray would become functional.
Recently when it updated to MIUI Version 13.0.2.0 Global Stable (SJOMIXM) it has completely stopped recognising the Sim and memory card Tray, you could see it appear and disappear as if trying to work before there's n error message about the .com.phone something not functioning and then it would shutdown and restart in the recovery mode.
Nothing seems to fix this issue so I'm stuck with a phone that I cannot use, I would like to know if there's a way to troubleshoot this issue or if there's a way to install another rom for this phone to function.
I'm familiar with troubleshooting phones but this one has been challenging me for some time now. I've read that there has been an issue with the sims not being recognised and that this new update was supposed to fix it, unfortunately it hasn't.
So far the best I can tell or think is that some of the firmware was corrupted, so I'm wondering if there's a way to completely wipe the phone and reinstall all software to somehow get rid of the problem.
Any assistance would be greatly appreciated

Make sure the bootloader is unlocked and USB debugging enabled. Download the Mi Flash tool and an older MIUI from Xiaomi's website or from https://xiaomifirmwareupdater.com/archive/miui/merlin/. I'm not an expert in firmware and ROMs. I just flashed my RN9 with a well-maintained ROM and just never looked back at MIUI. Also, try testing out the earpiece and the proximity sensor if the screen turns off once you cover the top. It could be that the IMEI numbers got lost. Try opening the dialer and enter *#06#, you should see a popup showing your S/N and IMEI numbers.
