SD Card and No Carrier // Solution - HTC 10 Questions & Answers

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

[Q] Mobile ID problem [sPIN]

Hello,
I have special SIM card issued by my operator which enables mobile ID use (with sPIN authentication) for connecting to bank or e-government. Works like this:
1. The user clicks the "Log in with mobile ID" option on a supported website
2. The phone displays a screen indicating that a connection is being made
3. The user is prompted to enter a mobile ID sPIN code into the phone
4. The screen on the phone disappears and the website is automatically reloaded with a logged in screen
It worked fine with stock firmware, but after I've rooted my HOX I'm not getting sPIN request screen anymore (step 3).
Have tried several custom AOSP or AOKP ROMs without luck, but found some of them partly working.
One I'm using right now is [ROM][4.2.2] Slim Bean - Endeavoru [STABLE][Build 7]. Mobile ID worked for first days after flashing it but later I was only able to use it for a few random times (after restarts). Then it works till next restart...
I was first thinking its an issue of incompatible apps I've installed or system settings I've mixed up, but somehow it works sometimes after restart (with very low success rate though). Also tried to restart into safe mode - it worked for the first time, but no luck for the next ~20 safe mode restarts after that.
I've also found hints it could be stk (SIM Application Toolkit) related problem. I can see SIM toolkit in my app list, though it doesnt' show up on running processes on developer tools.
If you're still reading this and have any ideas, please make some comments, maybe it would help me to get back on the right track, thanks!

Debricked, P2 sees SIM, asks for PIN, but does not register on network, SIM disabled?

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.

One M9 - Turning the Radio back on......

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.

OnePlus 3 not starting anymore

Hi,
I'm running a current Stock-ROM on my OP3, as provided by OnePlus OTA, never flashed something else. Just using the phone out of the box.
Yesterday, I deleted some cache data to free some space on my 99% filled up phone. Then I opened the gallery but not all thumbnails appeared and then it stucked completely. I holded the power button and it switched off. Now when turning the phone on a message appeared saying:
"The dm-verity is not started in enforcing mode"
After a few seconds it changes to the 3 animated points and this never ends. All I can do is switching it off, starting recovery mode or fast mode again with the same behaviour. I tried to connect it with my PC (W10) but it is not showing up.
How can I fix this problem without loosing my data especially my pictures and personal folders. How can I backup my data? I can still see them in recovery mode but how to access them and copy them? I could live with resetting the phone losing all settings and apps, but not my files.
What is your suggestion? Thanks in advance.
Ok, I just tapped on "Reset system setting", lost all apps and settings but it starts again and all my files are still there. Problem solved.

After battery replacement HTC one M8, Reboots to t-mob , until battery is exhausted.

After replacement of Battery, HTC one M8 cycles through Reboots to T mobile splash page, until battery is exhausted. I reinstalled the old battery and now I have the same problem with the old battery.
Now The only way to power down
• Disconnect the battery or
• Pressing –volume at reboot to show bootloader and select power down
I have TWRP 3.1.1-0 and a working backup file on the SD card, in my phone. I tried a “Restore”
The restore starts, but upon restoring Data, After the Progress: of 67MBof 13221MB,0%, I get the following red error message. “ExtractTarFork()process ended with error:255”.
Upon “copy Log” (in TWRP ) after a while the phone reverts back into the continuous reboot and no log file is copied to the SD card.
I hope it is not a hardware issue. The Htc case is open and on/off switch is not stuck.
Who wants to help me with this challenge?
