Samsung Galaxy J1 (SM-J100F) PUK Unlock issue

Hi, I have got an issue with my Samsung Galaxy J1 (SM-J100F) KSA version. I got the PIN wrong 3 times and the phone started asking for the PUK. I tried with the PUK given by the Network provider and it doesn't work. Removed the SIM and tried with a new SIM still not asking for PUK and hence no access to SIM Network. Then I tried to flash the ROM using Odin Downloader. Odin status shows "PASS" but the Phone is not booting up. I tried a few times but result was the same. Later used Kies3 "Firmware Re-Initialization" to restore the ROM. Now the phone boots up but asking for PUK. Someone please suggest me a solution. Thanks

[New D802] Problems: doesn't recognize SIM card after update and more crazy ****

Hello,
I bought a new LG G2 D802 32GB it was working fine with factory settings and 4.2.2 it did accept the SIM card without problems but after updating the OS to 5.0.2 I only get a "x" and the phone doesn't even ask for the Pin of the SIM card.
What I have done until now:
1. Tried to use the factory reset option but it didn't even start after the warning that the phone would reboot twice.
2. PC Sync did also not recognice the phone.
3. Did a hard reset but it did not help it stil did not recognice my SIM card.
4. Back to stock with the following method: http://forum.xda-developers.com/showthread.php?t=2432476​a. tried: Germany OPEN KitKat D80220D_00.kdz
=> Worked but I couldn't press most of the buttons for example I could choose a language but not press the shutdown button. It feels like the buttons are displaced.
b. tried: Germany D80220H_00.kdz
=> The same problem as I had with the last version.​
I really don't know what else to try so I would appreciate some help.
Thanks

try to download '' QuickShortCut Maker '' from playstore or the .apk from web pull it into your phone. and than install it.
at last open it and u have to try with the voice '' network'' or '' phone network '' and play a little until you find the connection type... (ps. the the sim card must be inside phone)
i've had the same issue with an F320 model after i flash a new rom and i find this solution playing with this program (quickshortcut maker)
if the problem remain. try to flash the .TOT firmware with this guide. http://forum.xda-developers.com/lg-g2/general/guide-vdo-flashing-kdz-tot-firmware-t3289950
pull out the SIM card anyway before u flash.

a3 2016 overheating warning when SIM installed

hi,
overheating warning appears on the screen although the phone is not hot. the phone doesn't charge the battery... this situation only happens when the memory card and the SIM inserted in the phone. no cards installed, no warning; everything is OK, the phone is charging, all functions are working without a problem..
i try different stock roms on Marshmallow and Nougat, it did not help.
any idea? thanks..

SIM cards not recognized

I have Android 8. Blokada & Magisk(with Mi A1 Camera Lag Fix Oreo module) are installed. And after rebooting my phone I get often a notification that my SIM cards were not recognized. I must reboot the phone again and then it works properly. Any idea what's wrong?
