Hi, below is a problem I experienced yesterday when i installed a new SD card on my device. I am also offering a solution which worked for me.
I installed a new SD card on my HTC10 yesterday. Following the installation I lost all carrier related services including phone and network. I noticed that although Airplane Mode is turned off on there was a contradictory message under settings. I received the following message "Airplane Mode is turning off"
This is what worked for me after many hard resets and disappointing trial and errors
Solution: Restart your device under "Safe Mode" by pressing "Power Off" a few seconds when you click the power button
So... I stared into the abyss, but I came back from the brink - unlocked bootloader, and the modem/calibration stuff got wiped during what should have been a routine TWRP flash from fastboot, and left me with no radios whatsoever. After flashing S048, and applying all the known OTAs up till S251, I got my wifi & bluetooth radios back, but it didn't seem to recognise my SIM (tried both slots).
After trying for almost a week, I also finally got the diagnostics mode going and was able to put a working QCN backup in place (thank you XDA and uploader).
So I flashed the LineageOS 15.1 20180413, and lo and behold, it sees the SIM and asks for a PIN to unlock it. So far, so good. Then (first time) Android says 'switching to mobile data, might take a while' but nothing really happens (I am on wireless; if I turn off wifi that doesn't make any difference though).
Under 'Network', 'Automatically select network' is enabled but 'Network' (right below) is greyed out. When I untick 'Automatically select network', it says 'Error while searching for networks'. When I re-tick it again, it says 'Registered on network', although nothing really happens.
Under SIM cards, it says slot 1 is populated, but says 'Mobile Vikings is disabled' (Mobile Vikings being my provider). The button to enable it is greyed out. Switching to airplane mode doesn't force anything either.
I've had a logcat instance open when toggling 'Automatically select network', but nothing related seems to show up. Any hints on what I could try/check? Or is this a coaster?
I believe that once you erase the modem stuff you'll always have serious problems restoring it. It seems like most people have to send the device in for service.
I've still no solution for an old P2 of mine and in that case I even had a TWRP backup.
Lenovo should really allow for us to flash stock images . An unlocked bootloader with LESS privileges makes no sense.
Wipe everything in twrp & flash twrp full backup which included efs & modem shared on our p2 forum. then flash Fastboot s48 only systemchuncks 0-14, boot & recovery then do 4-5 OTAs updates till latest one s251, you'll get you mobile network & calls back.
@eried1 Yeah looks like it
@amansehdav I have turned the P2 subforum upside down and I already tried this - restore a working S233 TWRP backup, flash S048 through fastboot, and upgrade with the OTAs till S251. No dice. Wifi and Bluetooth came back with that process, but the stock firmware would not see the SIM.
Hi,
I have a stock M9 that I've had from new.
Over the last couple of weeks, I have been trying to find a solution to my problem but without success.
The phone is stuck in airplane mode - when I look at the settings screen, I see that Airplane mode is greyed out with the status of "turning off..."
*#*#4386#*#* - phone info shows the GSM status as Radio off. When I select 'TURN ON RADIO' nothing happens.
I have factory reset, reloaded the stock image from SD card and tried various combinations of reboot with airplane mode off and on. The SIM card is fine - it works in another device. The M9 recognises the SIM is present and showd the IMEI and correct phone number from the SIM in the *#*#4386#*#* menu.
I have seen this in several other places on this forum; has anyone managed to fix it?
Thanks in advance for any help.
Hardware failure. Return to manufacturer.
Hello,
LOS 17.1 2020-12-15 on a Moto G7 plus.
Installation went thru with no error messages.
NFC,Wifi works. But no cellular/mobile networking, no telephony, "no service" message at the top bar.
When trying to dail a number, I get the message "please disable flight mode", flight mode actually is disabled.
In the settings the SIM is detected, IMEI is detected.
Chosing different network types, like LTE,GSM did not help.
Is this a known bug in 17.1, or is this a device specific bug? Any hint what I could do? Downgrade to previous LOS version?
I read somewhere someone suggested to use
fastboot erase modemst1 +2
But that made things even worse (lost IMEI, SIM not detected at all)
