Hello,
I have a strange behavior from my OP 7T pro.
Since the upgrade to OOS 11 final, (with latest magisk canary, no TWRP). I have a random detection of SIM cards in the phone. (the power off step do not help anymore)
I tried to wipe cache, then factory reset phone, but it doesn't help...
From time to time it is working, it drives me crazy because I do not know what to change to get it to work more reliably.
I looked for this topic with google but it looks like there is no "solution" to cure this topic.
Can you give me an advice ?

After reading similar experiences. I am tempted to try :
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
Any shared experiences would be good !
Happy Easter !
I found a fix on OnePlus forums:
switch off, remove the sim card tray, switch on, again switch off and insert the sim card tray with sim's of course, switch on, check for the same also in settings>>sim cards
This fixed it ! And sum cards are normally detected 100% upon reboot.
Try switching sim card positions, clean cards and the Insert the cards go in. Inspect for any damage. I had this problem on my op6tpro. They would get dirty from time to time. Don't think it is oos11.

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...!?
Hi everyone,
I have a moto E 1st gen with OS 5.1, suddenly one day it decided to not recognize the sim card and won't connect to Wifi either.
I took me some time but i could solve the problem, I did factory reset, I wiped the cache; it didn't work. I took it to service to get the simflex replaced, it didnt work, they checked other hardware parts, they couldn't solve it.
I did another factory reset in the meanwhile the phone began behaving weird;it would restart a lot and all apps began to crash.
I decided to go the hard way and flashed 4.4 through the computer.
Good news: SIM card and WIFI working again, yeiiiii!
bad news: OS boot, ask me for the language and a wifi and all the initial stuff; apps keeps on crashing a lot until the device reboots a minute after; and it ask me for the initial configurations again. and it does this again and again and again....
I checked on internet and all pages says that the app-crashing problem is usually a cache issue, the solutions are wiping cache or doing a factory reset; but I already had, several times.
someone told me the rebooting could be a power button issue, since the device had been opened a few times maybe the button got damage; but It won't explain why apps crash like crazy.
I'm out of ideas now, if you have an idea what could it be, comment below please and thanks.
Flash all partitions of your device with the factory images of your device, then wipe userdata partition and cache partition, dont forget that you need flash the 3 partitions of system sparce chunk, and erase the modemst1 and modemst2
I flashed manually; didnt use a flashfirmware.bat that I downloaded somewhere; and the phone is like new. thanks
At 40% battery or below I suddenly lose signal. Doesn't come back on even when toggling airplane mode. Only comes back after a reboot.
Don't know if it's firmware or ROM related. I've tried 7.3.2 - 7.4.6 firmware, still happens. Happens on all the Nougat(haven't tried any other versions not even Miui) ROMs I've tried(NOS, AOSiP, Pure Nexus)

1) Full wipe system, data, cache, dalvik, internal storage and format with must use type "yes".
2) install firmware and ROM.

I always do that when flashing(I get OCD even though I know some parts aren't necessary sometimes). But problem still exist. Don't know if it's because of auto select network or something. I think there's only 1 time when signal isn't lost for 1 day. I just have to live with one reboot a day.
I'm also facing this issue. This happens every time to me no matter what my battery percentage is, i also flashed all kinds of miui roms even the oldest lollipop roms, but the issue still persist. Rebooting the phone only brings back network for sometime ( 10 minutes approx.). I also tried the same sim card on different phones, and it worked good. Also i have a second 3G sim which works nice, i think the problem is with 4G sims only.
If anyone has any fix please share.. :crying:
I was facing this issue few days back, now it's showing no sim card.
Only way I find to solve this issue is removing sim card, restore miui from fastboot, clean flash rom and insert sim again after first wizard setting
I have infocus epic 1 device and its standby is terrible from the day of purchase(>2.5%/*h).It stays awake 100% of time.I rooted the phone on sole purpose of fixing it.after doing some research now i am sure it's something related to radio layer interface because when i don't install sim card mobile goes deep sleep 98% of time.better battrey stat show's kernel wakelock ttyC0 as main culprit.i think com.android.phone is the reason behind it.i have found one tedious solution to fix it.first i ve to freeze the package com.android.phone pluck the sim out restart the phone put sim back in and defreeze the package.but rebooting the phone again starts the problem.but i want to completely fix it without need to do so.also it would be hepful if i can some how block mandatory restart after inserting sim in the sim slot so i dont have to freeze and defreeze the package com.android.phone
I think you should try a (few) different SIM card(s). It may be the card itself that causes problems.
Then, I’d reboot the phone, after entering the PIN, wait a minute of so for everything to initialize, and then check dmesg (aka the kernel/driver log), or even logcat for that time period.
Also, if you can, try making a complete backup image of your system (all partitions), and
1. try a factory reset of your phone (ideally flashing the original system on there after the factory reset), or even
2. flash an older Android (6? 4.4?),
and see if the problem exists there too.
You should be able to find the newest/best case where it works, vs the oldest/worst case where it doesn't, and then look at what’s different between the two (with some graphical diff tool, using dmesg and logcat output among other things, for example) , especially with regard to your problem, to find the answer.
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
