Weird D855 Bootloop - G3 Q&A, Help & Troubleshooting

As weird as it sound my D855 bootloops when any SIM card is inserted .. I've been running cm13 for a very long time and this happened yesterday out of a sudden.
I tried clean flashing but i didn't fix it.
Then I tried flashing another rom, I tried fulmics 4 (since the file was already in my sd card), The phone booted with the SIM card but there was no signal ( no bars ).
Anyone can help ? thanks

[q] sim card error

Hello. I've a new problem with my phone and thenSim Card. In the day, i have suddenly an error message saying that my sim card is missing. The phone reboot and after it can be good all the day or i can have the same message few minutes later, and same reboot. I've tried this sim card in another phone without problem.
An idea ?
I've made a recovery and i had sill the same problem
my Firmware is 10D
Thanks
Maybe it's hardware error?restore your phone to it's original state and send it to warranty.
Have you swapped the sim while it was on?the g don't support hot swap,you need to turn off the phone before changing sims.

Mine just started doing that around the same time yours did... odd. What ROM are you using? What LGOG variant?

LG G3 strange problem

hello everyone, my D855 have been running cm13 fo a couple of months now. I usually update nightlies every couple of weeks or so.
Today, my phone just rebooted ( which happens sometimes) but this time it's stuck in the LG logo..
So, I went to recovery ( 2.8.6.0) and wiped everything except SD card, then when I tried to flash the rom the phone just rebooted as soon as the installation began... I tried again with different roms (I even tried fulmics) but the same problem persists; the phone reboots as soon as the flashing process begins ( exactly after the line "patching system image unconditionnaly" )
I even tried updating recovery to 3.0.0.2 and again the same problem.
Here is what strange, I tried to move the rom zip from the SD card to internal storage with the twrp file manager , but as soon as the copy starts the phone reboots and hang in the LG logo...
I was thinking maybe my internal storage is damaged ( is that a thing on smartphones ? )
will installing the v30B kdz solve the problem ?
Please I need an answer. THANKS
note : recovery and download mode are accessible
D855 16GB
You may try flashing a KDZ or TOT.
If it doesn't work it may be that your phone is damaged.
