[Galaxy Note II Q&A, Help & Troubleshooting] fightcookie:
Hi,

when I started using my Note 2 LTE with an LTE sim card (tested LTE long ago without problems), running CM11 nightly from approx. 1 month ago, it started to reboot randomly. But it also happened with the other sim card without LTE, that worked fine before.

Updating CM didn't change anything.

Then I flashed the newest DBT stock ROM for the N7105 (N7105XXUFNE3_N7105DBTFNE1_DBT) (without knowing about the KNOX bootloader...). The behavior was the same with any of the SIM's inserted, but without SIM, it took hours compared to minutes or seconds for it to reboot.

Then I tried to flash the N7105XXDMB2-XEF-Service-Firmware (at this moment, I remember it was warranty void 0 and showed sw rev invalid magic string, EDIT2: perhaps did'nt want to downgrade the bootloader to a non knox version? but without also flashing bootloader it now doesn't flash, trying another old 4.3 formware which is without bootloader perhaps, but didn't work, can I remove it somewhere and how?... /EDIT2) with separated CSC, Bootloader, PDA, Modem and PIT. I also ticked repartiton.

Here the log output:

"<OSM> Enter CS for MD5..

<OSM> Check MD5.. Do not unplug the cable..

<OSM> Please wait..

<OSM> FULL_MODEM_N7105XXDMB2.tar.md5 is valid.

It said "set partition" in the box where "PASS" also appears for more than 10 hours, then I unplugged it.

After unplugging:

"<ID:0/008> There is no PIT partition.

<OSM> All threads completed. (succeed 0 / failed 1)

<ID:0/008> Removed!!"

It didn't change anything, but when making a factory reset it even rebooted instantly.

I also flashed the pit file with repartition alone. but same behavior.

But after all of this, it was repartitioned.

I successfully flashed philz touch cwm, didn't change anything.

Now I flashed the newest DBT (N7105XXUFNE3_N7105DBTFNE1_DBT) again. No restart without SIM, but didn't test it for hours. With SIM, instant restart after entering PIN. And what's really strange... now it has an instant bootloop without SIM, too. Factory reset made it boot successfully again.

Is something wrong with my radio unit or what else could I try?

EDIT2:

I now flashed philz recovery to gain root access, made that in the recovery, then I installed adbd Insecure v2.00 to have root adb when booting up. Without Sim card it was again fine for a long time and then i put my sim card in and logged proc/kmsg and logcat to files on my device via an adb command.

Here they are, I really hope some can have a look at it and perhaps find anything that helps!

/EDIT

EDIT3:

Here's the last_kmsg log from the same crash:

From another crash: pastebin.com/q7fj4byt

And the 3rd crash: pastebin.com/AV7RPquK

/EDIT

EDIT4:

I managed to get kernel logs even after adb disconnects! There's also one last_kmsg now that shows some logs before the restart, that looks promising!

/EDIT

Any help is much appreciated!

Thanks in advance.
