THINGS TO TRY:

This post will cover what you can consider trying to help alleviate your issues.

NOTICE: WHAT I COVER BELOW IS YOUR RESPONSIBILITY, NOT MINE:

I will try my hardest to give you clear, concise instructions on what to do, but you are responsible for carrying them out, if your phone bricks, makes funny noise, catches on fire, kicks your dog, or even joins ISIS, it isn't my responsibility, so if you brick your device, don't blame me.

● First up, because I feel it is one of the safest methods to try is NYiCoN's method.

This is his method, not mine, I am only paraphrasing it here because I want to keep the post continuous.

● He provides the files you need to download at this Google Drive link here.

● You need to download all the files from that link and hold onto them.

● After downloading files, proceed to put the phone into Download Mode.

● Open the ODIN binary provided in the Google Drive and connect the phone to your PC.

● Click on the CP button to choose the "N910TTMB1COD6_Modem_CP.tar" file.

● Proceed to click on the AP button and choose the "N910TUVU2EPE3_N910TTMB2EPE3_N910TUVU2EPE3_HOME_AP.tar" file.

● Go ahead and click the Start button to begin flashing.

● Once flashing is complete, pull the battery on the phone and immediately go back into Download Mode.

● Click on the CP button and choose the "N910TUVU2EPE3_CP.tar" file.

● Click the start button to begin flashing.

● Once ODIN is finished, pull battery and open Samsung Kies.

● Proceed to perform an Emergency Upgrade in Kies to force phone to EPG2 Stock firmware.

● Once Kies is done, let your phone start up as normal and play around, see if this helped.

● Second thing to try is justforgot's method which involves wiping all the partitions in TWRP each in a row before flashing a rom.

● The only thing I will mention is the eMMC tends to run smoother when all partitions are wiped before flashing, but this also tends to wear out chip worse. I only recommend this if you don't care about life span of phone, or you aren't worried. If you need the phone to last, be weary as this can speed up deterioration of the memory provided the eMMC chip is the problem.

● Last method for right now is something I thought up with the help of maxrfon's logcat output which involved /efs write errors.

● I should point out that this method also adds to deterioration on the storage chip, albeit to a lesser extent, a risk still exists. Also, this only works on TouchWiz roms as on CM roms, TWRP won't let you backup the EFS partition.

● It simply involves backing up /efs at least once and then restoring about 7-10 times, around 2-3 time, it will take up to 2 entire minutes to write 14 megabytes, afterwards restore should be quick again. That should help a little, but it isn't to as great an extent as the upper methods do.

● BONUS!!! World War 3 Atom Bomb method. This was something I mismashed with other methods along with my own knowledge of ODIN. This method will wipe your chip as clean as you can possibly get it without brick. This also has the highest rate of deterioration, be careful, this method is a doozy.

● First, get ahold of PIT files for your device, I won't post links because malhandling these files can be bad. You can get bricked if you aren't careful. SamMobile is a pretty good place to find PIT files.

● Second, get ahold of a stock firmware you want to use, or you can tie this in with NYiCoN's method above for extra chance of a good flash.

● Open ODIN and connect the phone to the PC in Download Mode

● Click the Pit button and chose the PIT file you downloaded.

● Proceed with NYiCoN's Method except checking re-partition and Nand Erase All, during the first flash session.

● Once you are ready to boot, you will be taken to recovery to flash the system image, but after that, you are stuck at the bootloader screen forever. You need to go back into recovery, wait for Installing System Update to pass, then do a factory reset because the Nand Erase removes the data partition. A factory reset recreates this data partition, reboot and you are golden.

Last post will be what you can do to help diagnose the issue further. If you so please.
