HTC M8 Hong Kong Help (No version_main)

Hi everyone!
I recently unlocked my bootloader and rooted my m8.
I tried using firewater to "s-off" my phone and unfortunately, it did not work out. The way I understand it, I cannot install stock ROMs (such as the 5.0.1 GPE) without "s-off." Now, I want to unroot my phone and stick to waiting for the OTAs to roll out instead.
I followed the instructions in the "returning to stock" thread and noticed that I have no version main (see attached image). I looked around the forums and saw that the advice was to flash the latest TWRP version. Since I'm stuck with a phone that I cannot update, I'm trying to be careful now. Can anyone please confirm if flashing the latest TWRP will bring my version main back?
The noob in me also has a few questions/requests as well:
1. Since my phone is rooted, I cannot receive OTA updates and upgrade to lollipop once these updates roll out?
2. Please tell me which files to download to return to stock. Just trying to be really careful this time around.
3. Lastly, is it also true that I can only install custom ROMs once have rooted? As to stock ROMs, I can't install them until I get "s-off"?
Thanks a lot, everyone! Cheers!

Do I have to flash the latest TWRP version before proceeding?

Need General GS3 Help and Info

Hello folks.
I am new here and am not sure how it all works so please forgive me if I have posted in the wrong spot or am asking something that has been beaten to death already.
I have a AT&T GS3 I747 . I received the OTA 4.4.2 update for it and used it just fine. One day i got a bug in me to root and flash it. I rooted it, installed CWM 6.0.47 or something like that and installed Gummy Rom running kitKat 4.4.4.
I would love to return my phone to 4.4.2 with or without root. Is this possible? I have read and read to NOT take these backwards after JB 4.3
I have looked until I was blue in the face for a rom to use and am drawing blanks. I probably found one once and didnt know it. I can flash and all that and do it regularly, I just don't understand all the fancy lingo so I probably overlooked what I am looking for.
So bottom line, is it poissible for me to go back to stock 4.4.2? I would love a stock rom minus all the at&t bloatware since I will be unlocking it to straight talk.
Thanks for your time and once again, my apologies for dragging this all up again if it has been covered already.

First thing to do is update that custom recovery, or at least confirm you're on the latest version. I think that version you quoted is a little dated, and that has potential to cause you some problems flashing ROMs. An easy way to get and install the latest recovery is an app called Flashify.
Next have a look around the development section: http://forum.xda-developers.com/galaxy-s3-att/development
You'll find some debloated TW ROMs for that stock feel without the AT&T & Samsung junk along with plenty of other good ROMs to choose from.

It's wise of you to be cautious @DjPorkchop.
You are correct, you should never again downgrade your bootloader and modem, also called firmware and baseband. The very latest AT&T OTA updated bootloader and modem to NJ1, it is part of the 4.4.2 stock install. The OTA before that loaded NE4 bootloader and modem, they were also in a 4.4.2 stock rom, but you can not downgrade to them if you are on NJ1. AT&T has not issued an newer bootloader and modem than NJ1.
The good news is that the custom ROMs do not flash bootloaders and modems. You are safe to install even a 4.4.2 custom ROM on NJ1 firmware for this reason. There are stock system dumps available, with these you have to use caution because the bootloader and modem may be present, not always however. Talkingmonkeys has a TouchWiz based 4.4.2 ROM, TMS3KK, that is available in two versions, the second is heavily debloated. I am using the 4.3 Android version and will be soon updating to the heavily debloated 4.4.2 version. (He's still doing some minor theme tweaking on the newer version.)

How do I tell if I am on NJ1 or NE4? As I recall, I got the 4.4.2 update and all but immidiatly after had my phone shut off. I don't recall ever getting a 2nd update to 4.4.2 as long as my phone was active. I have been known to be wrong before though.
And I thank you much for the info. I will go check that thread out as soon as possible.

There is a "Samsung Info" app in the PlayStore that will give you the info.
Or, in a terminal emulator you could enter:
Code:
getprop ro. bootloader
and
Code:
getprop | grep version.baseband

Thanks for letting me in on that app. It shows me on NE4.
So off I go to figure out what I am going to do to this phone. I am going to visit that thread you mentioned to me and see if I can make heads or tails of it and get a rom for this phone. I ike Gummy rom but it is a bit to much for me. I really want to get back to as close to stock as I can get safely without bricking my phone.

Ok so I revisited that page again and I can't make heads or tails of what to do. I know for certain I am on NE4. That is all I know. Any suggestions from that page to get me as close to stock as I can? I see there is a stock theme revert as well on that page.
Sorry to be such a pain. I am one of those guys that figured out how to root and flash and never should have.

Have a look here to return to stock: http://forum.xda-developers.com/galaxy-s3-att/general/ucuemjb-to-ucufne4-firmware-update-t2808654

That room comes with a dark theme. The revert is not needed unless you want the lighter colored stock theme. I use the dark because, supposedly, a dark setup is a little easier on battery drain compared to light or white themes. I didn't install the extra battery mod, he had enough options built into the rom to suit me.

Downgrade M8 back to Lollipop to KitKat

I've searched the forum and havent found a specific answer to my question. I am currently running 5.0 with the viper rom and its pretty damn sweet. my problem is a lot of my apps and some of the xposed modules wont work on lollipop but are compatible with KitKat. so obviously i want to go back.
is there any way to go back to kitkat without having to plug my M8 into a computer?? i would basically like to do it remotely and on demand, you know flash OS back and forth like you can do with a rom. can somebody help me out with the process if it is at all possible.

You should be able to run a KK version of Viper (or other ROM) with Lollipop firmware, as least from what I've read from reports by others. While old firmware causes problems with current ROMs; the opposite has been found to be a a different matter: firmware has been found to usually be backwards compatible.
You can always make a TWRP backup of your current setup. Then try a KK ROM, and if you have issues, just restore back to LP.
If you do run into issues, then you probably do need to downgrade your firmware to KK (need s-off to downgrade firmware; and not sure if there is a computer-free way to flash back to KK firmware).

[Q] Best way to upgrade US i-467 (AT&T) to 4.4.2

Sorry for the post, but I've looked elsewhere and searched can't seem to find the best, fastest, and easiest way to accomplish this.
1. I have an AT&T GN8.0 (SGH-i467) on 4.1.2. Build CAMF2. I'd like to upgrade to 4.4.2 The device is rooted, with locked bootloader and stock recovery. I also have an AT&T Pay-as-you-go SIM installed.
2. I'd like to end up on 4.4.2 rooted. I have never been offered the 4.4.2 upgrade on my device and I'm not sure if it's because I have a PAYG sim or it's cause I'm rooted.
3. I'm not afraid of Odin, download mode, etc., so if anyone can help me figure out the best way to get myself upgraded, I'd appreciate it. If you want to point out some posts, threads, etc., that can help, that would be great too, but I've scanned all of those and it all just gels together to where I'm not sure what's what anymore.
Thanks.

Don't try to update via OTA with a rooted ROM as it may cause a softbrick. I recommend unrooting and trying to update or flashing a stock ROM from sammobile.com and then try to update to KK.

Thanks, that make sense.
Going back to stock shouldn't be a problem, but any thought to if I can update to 4.4.2 with a PAYG SIM? If not, is there a flashable file and method that you can point me to?

It has been my experience with various phones that OTA updates should work regardless of whether a sim is or is not inserted.

Get from Rooted Lollipop 13b to Stock Marshmallow

I'm tired of the problems and struggle I've had attempting to use my rooted G4. I'm currently on 13b rooted and it's been giving me problems. It randomly reboots and doesn't start up at times. And it's so sluggish. I've gotten a replacement because I flashed the wrong kdz. I just want my phone to work without all these problems. I just want to get to the stock Verizon MM for my G4. Is this possible?

You should be able to flash the MM kdz - they can be found here in the general section. Be sure to verify it is the correct kdz.
Keep in mind once you go to MM you won't be able to achieve root without downgrading back to LP. I think there is a downgrade thread here in general as well if you need it.

Thank you I just downloaded the KDZ and flashed via LG UP. It installed without any problems. I'm aware that you can't root on MM, I'm ok with that. I need a break from rooting after all of this. Thank you I appreciate it!

Glad to see someone here not happy with rooting the G4. I don't find it worth the risk or the benefits worth it without the ability to flash custom roms. I've never rooted a phone without there being a way to install a custom recovery.
For anyone interested, The Android Central podcast discussed the topic of rooting and flashing roms a bit on their most recent episode. Most of them agreed that there isn't as much of a need anymore to root and flash roms and that it's kind of died down a bit. Features that people used to have to root their phones for are now available on most stock roms.

i know at the end of the video it says close the app, but dont, just start it and you be upgraded to MM in no time just make sure upgrade is checked
if you want to start fresh, then you can just do what my video says to get refurbished checked
if you upgrade with a rooted rom you have to factory reset your phone inorder for MM to boot
