Hi everyone,
I own an HTC One M8 which went on bootloop a week ago. The bootloader was unlocked before that happened. I tried everything to solve the problem, even a factory reset, but didn't work.
So I tried Lineage OS. First I install the latest TWRP recovery available, then the last nightly that came out for M8, in the end the Gapps package. Finally the bootloop was over.
Now the problem is that my sim card is not recognized. No data, no calls. I tried different Lineage OS nightlies, different ROMs with Nougat, I tried to power off completely, the airplane mode, to put some tape on the back of the sim, nothing worked.
Before the bootloop, the sim was detected even if sometimes the signal come and go.
However, everytime I flash a new ROM, at the initial setting stage they recognize that my sim card is italian (which is correct).
Can anyone help?
Thanks and cheers

After a normal reboot of my phone, it suddenly doesn't read my sim card anymore. When I turn it on, I'm not asked to enter the pin code and the phone doesn't connect to the network.
If I go into settings and change the pin code, or turn it off, I'm asked to enter the original pin code, so in that way there's still a connection to the sim card.
When I've done any of the above, the sim card seems to been "activated", and the phone connects to the network, and everything is as it should be until the next reboot. Then I manually have to "activate" the sim card again.
The phone has worked without any problems for a long time with the current CyanogenMod 9 custom rom and my current provider, and I haven't changed anything that suddenly can cause this.
Some suggestions to what can be wrong?
Does the sim work with other phones ? If so, it probably isn't a problem with the sim. In that case, try a factory reset in the first instance.
If that fails to work, try a fresh/clean install of CM9. If that doesn't work, reflash a Gingerbread stock rom & see if the problem persists. If the problem persists with a GB rom, then it's likely to be a sim/hardware issue.
The other thing that comes to mind is have you flashed a recent CM9 nightly ? This might explain it working OK previously with CM9 & not working now. Obviously CM9 is beta, and something funky might be going on with a more recent build/nightly.
I've now finally managed to find another phone and another sim-card.
My own sim-card works fine in the other phone - and when I put the other sim-card in my own phone it doesn't ask of the pin-code and it doesn't connect to the network.
So I believe my phone needs a complete reset - when I've got the time to do it...
One strange thing is, that at one reset earlier this week my own phone asked for the pin-code - but only once...??
I think I've found the problem. Either it's caused by Avast Anti-Theft alone or it's a combination of Avast Anti-Theft and CyanogenMod 9.
I believe it's the last one, because everything worked fine during the first time I switched from stock ROM to CM9, but then suddenly the error with the pin-code occured, and I could be caused by an update in the CM9 version.
But when I restored factory settings on my phone and started again from zero, everything was okay, and I was promted to enter my pin-code. It was the same when I restored my apps and data with Titanium Backup, but then when I installed Avast Anti-Theft the error occured again.
Actually I restored my phone once again just to make sure, and it was the same - when I installed Avast Anti-Theft, I was no more asked to enter the pin-code and the phone did not connect to the network.
So now I know what's wrong and maybe also why - but I don't know how to solve it...!?
Hello,
From 2 days till i gave up, i was trying to put @Psycho CM mod alpha 4 release. Well i Almost did it but have some Bootloop problems.
'When the sim card is out, well everything starts normally. When i put it in, the phone stucks in the booting logo, and after 10 seconds it restarts, and its the same, bootlooping. i tried everything, wipe data / factory reset, but nothing seems to fix this bug. Without SIM is ok, but i need my SIM card in, and I need my phone in CM7 Alpha 4 working. Please help.
Hello everybody!
I was on ultimate v8 when my phone started rebooting in recovery without any reason, and entering recovery.if i restarted the phone i didn't had signal.
the phone worked properly without the sim card (tried two cards, it had this problem with both of them)
i thought it was a rom issue, so i flashed the stock rom, relocked the bootloader and used sony update service to repair my phone.
i didn't install any applications, and for a couple of hours it worked normally. afterwards though it lost signal again and started rebooting.
did a clean install again with no results.
any ideas what how should i procceed? is there any way to fix it or shoud i visit a service point?
ps sometimes it seems that sim cards are not properly recognised. it's not that it has the sign, that shows that there is no sim card, however sometimes i restart the phone and it doesn't ask for the pin code

hmm...do a factory reset using cwm then flash stock ICS .54 rom & see it works or not.
i've wiped data, cleaned cache, dalvik cache etc many times while i was on ultimate. i've also flashed the stock and did factory reset via the menu in the phone as well via sony update service... i was thinking of flashing radio, but couldn't find the file...
I wiped my LG G2 (vs980...unfortunately) on Monday from an old custom ROM and installed a new CM mod (13). Since then, the phone won't recognize any SIM inserted. I wiped all again, and installed CM 12.1. Same deal. Went back to CM 13 and nothing. Now upgraded to RR 5.8.2 (latest they have for the vs980 model) and still nothing. Everything else works great (apps, wifi, bluetooth, etc), but it still does not see any SIM. I also noticed that when I go into settings and select Cellular Networks, I get a "com.android.phone" error (Not that annoying "Unfortunately..." mess people used to get and it asks if I want to close the app. I have tried clearing all the caches and app data, going into test mode and turning off the radio (several times) for up to an hour, powering fully off, removing the SIM, leaving out for an hour before reinserting and powering back up, and even changing the IMEI number and nothing has worked. By the way, using TWRP 2.8.6.0 to flash my drive.
Oh, and I used 3 different SIM chips and they all work fine in a PUK.
Someone please help. I can't afford a new phone right now.
Thank you for reading my question, really appreciate if someone can solve my problem.:angel:
I have a LeEco le 2 x526, in which i removed the stock EUI rom and booted a Custom Rom Lineage OS, everything was well and fine for about 2 months then one day suddenly the phone froze and switched off.
I tried factory resetting my phone, re-flashing the phone but nothing helped it still does the same thing, i have to hard restart my phone by pressing and holding power button, when the android boots all the time and dates are messed up after getting the signal everything is back to normal.
I tried restoring my phone to stock Rom by recovering from backup image before installing custom Rom but after installing, but the phone is stuck at first boot screen, even tried downloading stock Rom and tried that same result. I waited about two and half hours before giving up. If i try to install again Lineage Os it boots correctly with no problem. But can't restore it to stock Rom.
One thing i suspect when the problem started was that i change my sim card to a new one, before i was using Jio 4GLTE sim card in the phone & then i switched the sim card to Airtel 4GLTE. Is this due to the sim card or signal or my phone is having issue. The Airtel was alwasys my secondary sim in my phone but never used it for data Jio was my data sim card, now i am using Airtel as my data sim card.
Hello, do you find any solution??
