rooting and TWRP update problem

[shaul123]

hello all.
im using a G2 D800 AT&T, and since i have a tethering problem which i was assured would be fixed if i installed a new ROM.
so i went ahead with a guide for cloudyg3 rom, rooted using towelroot and verified with root checker, all is well.
installed TWRP with freegee- the TWRP version was 2.6.3.3 and i was told i needed to upgrade it to at least 2.7.1.. thats where problems started.
i couldnt for the life of me upgrade it to any version, 2.7.1 or higher, and TWRP showed a loki.sh problem. thought maybe unrooting and starting the process all over would fix it so i deleted all my apps, then unrooted with supersu.
tried to root with towelroot and no go. immediately after trying to root, root chekcer gave me a "device is not rooted" answer (before there was no problem), and the device reboots just after im trying to remove towelroot from the task manager (center button).
did i mess up my phone so it cant root? is there a way to check that\ other root methods?
please help

I can't give you links (I don't know the G2, but the G2 forums at XDA probably have loads of links), but reflash the stock ROM and recovery. Once you can do that (it's scary the first time, you're a little nervous the second time - by the fifth time you're bored, angry that you had to do it again, but not worried), you can try things - like flash the latest TWRP first (if you do that, immediately make a backup of the ROM and copy it to a computer, so if it happens again, you just install TWRP and restore the backup), or install a different ROM or anything. (Make a TWRP backup of any ROM that works, even if tethering doesn't. There may be something in that ROM you like, and if you have a backup you can always restore it, use it for a while, then restore a different ROM.)

Check that the phone actually supports TWRP later than 2.6.3.3 (it probably does - it's just something I'd do to be sure). See if there are other ROMs that support tethering on your carrier. Just ask before doing if you have any questions. (If it's about something you saw on XDA, ask on XDA - the person who write it is there. Maybe here also, but definitely there.)

dont think i quite got you-
right now the problem is that my device is unrooted and when im trying to root it with towelroot the device reboots and the root doesnt go through.
so i think i need to find a solution to that before i flash, which can be done only if the device is rooted?

so i i got the device rooted and all, installed TWRP through freegee and downloaded newer version (2.7.1),
and when i booted the device into TWRP mode and tried updating to 2.7.1. , THE SAME THING HAPPEND AS BEFORE-
i just cant update the twrp to more than 2.6.3.3., no matter what version i try (2.7.1 or higher).
getting error message of: assert failed: run_program (temp\loki.sh)
error executing updater binary in zip \sdcard
error flasing zip \sdcard\download\...
updating partition details.
and getting two options: wipe chache\ dalvik, and reboot system.
this happend to me with EVERY TWRP UPDATE I TRY...
and from my understanding i must update twrp to more than 2.6.3.3 before trying to flash new roms.

thats the problem i had before as well, device simply wouldnt update to more than 2.6.3.3

thanks...
