Hey guys. I know for sure there is another thread about a similar problem but the biggest problem I'm having is figuring out what to do next, or better yet, what did I even mess up?
I made a thread a couple days ago here asking about the LTE option on my phone and how there was none. It's an Intl' phone and therefore I guess doesn't work on Canadian LTE networks.
Before we start, I'm using TWRP 2.7.0.0 . My phone is the UAE version of the D802, which is the D80220C. My current custom rom is Liquidsmooth MS3.2 .
So I found a list of modems and flashed the one for Bell. It was for the D803, but the thread I was looking at said it was cross-compatible so I assumed that meant it's okay for me to flash it on my phone.
Even so, I backed up my EFS partitions just to be 100% sure. I even used the .zip file that automatically backs up the current modem files. So I thought there was definitely a way out if it didn't work.
I will give you the full story of what was done and maybe I can get some guidance on maybe something I did wrong.
1) I flashed the D803 Bell modem.
2) Reboot to system, LS3.2 hangs on start up. Tried a hard restart to see if it wasn't a fluke. Nothing. Still hanging.
3) Figured the EFS files were toast, so I ran the restore .zip for my EFS. Reboot, and still hanging.
4) Said WTF? and restored my first stable rooted stock rom. It booted into the rom fine, but when it got to the lock screen I saw the "Service Disabled" and the phone quickly crashed.
5) Didn't even attempt to restart on that rom. So I tried a couple terminal commands to copy the modems1.img and modemst2.img files to corresponding partitions. Copied both just fine, but no change. Still screwing up.
So, this is where I am so far. I am in the process of downloading the D80220C UAE .kdz file so I can try to flash that one first. If that doesn't work, I'm really at a loss.
When I read into this some more, all I see is people who have totally wiped their EFS files and having to spend a whole bunch of time using a bunch of different programs to get in an recover the IMEI number.
What do you guys think?
Some good news right off the bat. I found a KK baseband for D802 and flashed it. So now I was able to restore my LS3.2 rom and boot into it fine. I see my IMEI and MAC address and can get WiFi at last!

[H918] Successful root/fastboot unlock from 10J -> No roms are flashed successfully
Hi folks, wanted to share my current state of affairs with trying (and failing) to install a new rom on my LG V2O. Here's the order of events
Received brand new sealed-in-box LG V20 from T-Mobile from a third party seller that came in firmware 10J
Followed all directions to successfully perform dirtycow unlock
Installed TWRP (3.0.2-1)
Backed up, but mistakenly deleted the backup after trying to install Megarom in an attempt to do a clean flash
.zip flashed correctly, but hits boot loop upon reaching LG screen (even after waiting 20+ minutes on first boot). T-mobile screen never pops up
Can access TWRP still and ADB commands
Basically now, I've tried looking at as many H918 rom threads as I could but every single rom I try either: never completes flashing OR if it does complete flashing, the device never boots (either bootloop or stuck on the LG screen). I've never seen the device get past the LG screen for any reason. I am desperate for help on this matter as I have royally screwed up trying to provide a nice gift for my partner but was apparently way in over my head with trying to get a fresh rom on this thing.
Can anyone provide assistance as to how I can roll back to a stock rom? I'd be willing to give up root/recovery. All of this was spawned from wanting to be able to unlock the carrier but I have decided I'll just pay for the sim-unlock service if I can get this back to stock. Would be willing to provide some PayPal cash for someone who can help me out with this matter.
Flash to 10j kdz firmware located in the thread with all the firmwares. You`ll need lgup to flash it.

I have a Verizon GS5 that has been towelrooted on 4.4.4 for close to 2 years. It's worked ok, but I've started seeing various issues that required a factory reset. Since I'm back to no settings, I was thinking updating the OS would be a good idea. I would like to move to either Lollipop or Mashmallow but it looks like the latter may be a problem with my phone (CID 11 and Verizon) while keeping Knox 0x0.
I'm having a problem following the guide that I've found here:
https://www.androidinfotech.com/2016/07/root-samsung-galaxy-s5-sm-g900v-verizon.html
The issue is that I can't get the phone to connect to my PC for Kies or ODIN. It fails to load the MTP driver for my GS5 but works fine with my wife's GS5. Hers is stock Lollipop or Marshmallow and mine is still on JB but is rooted.
I guess what I'm wondering is what my options are. Should I remove root so that I can hopefully connect to the PC to transfer the files over and updating? Or, is there something else I should try first? I haven't worked on many phones and I'm a little nervous about doing something irreversible at this point. I don't know that I need Knox at 0x0, but since I can't get back if I trip it, I'd rather not trip it.

Try to dial *#0808# in the stock phone application.
You should see a menu with several options.
Select "MTP+ADB" under USB settings and press "OK".
Then you'll be able to connect your phone via MTP or ADB to your PC.
If there's no menu, then (assuming you're rooted) open a good file browser (ES, Root Explorer or something) and open the file /efs/carrier/HiddenMenu (it's a simple text file) and replace OFF with ON there.
Save the changes and reboot the phone.
Now the menu should be operational.
Unfortunately, I already tried to update to 6.0.1 so this very helpful info is a little to late.
I followed all directions on the linked page above but didn't get things working. I repeated 2 or 3 times now and I'm clearly missing something. I can get through installing busybox, but then when I reset, it hangs at the samsung screen and just vibrates 3 times repeatedly. I'm going to have to figure this out tonight as I don't really have a backup phone.

Currently root is impossible for MM on G900V CID11.
Impossible means you cannot gain it now, most likely it's forever.
There's no internet site which can help.
You must choose: root on LP or unrooted MM.
You must decide if you want a stock ROM or something (TW-based) else too.
It's a good idea to flash and use a stock firmware for the time while you're thinking.
Interesting... I guess I must have been reading things wrong because I thought I could go to MM with root. I'll try going to Lollipop then but first I'm going to just flash back to JB 4.4.4.
I downloaded 4.4.4 from Samsung and was going to write it with Odin, but it says FAIL when I try to flash. I suspect I just tripped Knox...
SW REV CHECK FAIL : [aboot]Fused 2 > Binary 1
I'll look around to find a guide, but if you have a suggestion, I'd certainly listen!

This means that you've upgraded your phone's firmware while experimenting.
Now you cannot directly flash 4.4.4 with Odin, you're limited to 5.0 (BOK3) and above.
Ok. I'll read the guides on the head of this list and see if I can find the right information.
FWIW, I was following the same how-to that most of the stickies point to and say is safe. I wonder how I got to a position that I'm in now when I did the same as recommended. Painiac's thread points to the same thing I did:
https://forum.xda-developers.com/ve...al/guide-painiacs-essential-guide-to-t3319848
I think I may have tried to flash a MM stock rom though when it got into a boot loop. I suspect that would be the issue.
Bootloop is not a problem in this case.
Just reboot to the recovery and perform a factory reset from there.
The phone will boot but the first boot will take 10-15 min.

Marshmallow can not be rooted on CID 11 devices. The Samsung drivers are found here: https://www.samsung.com/us/support/owners/product/galaxy-s5-verizon You can follow the 5.0 root guide here: https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529 to downgrade to 5.0. If you want to downgrade past that to a version lower than 5.0, you will still have to follow that guide then follow the instructions here (I recommend you to follow the root guide for 5.0 above then skip steps 1 and 2 on this page): https://forum.xda-developers.com/ve.../guide-downgrade-to-kk-nk2-ncg-mm-lp-t3686858 . You can find stock firmwares here: https://forum.xda-developers.com/showthread.php?t=2784880 (stock firmware, kernel, and modem files) and if you get bootlooped or bricked, just reflash the combination file from the root guide. If you want to root 4.4.4, follow the downgrade method using all of the NK2 files but the flash the NGC kernel, run through the setup, then use towelroot and flash the NK2 kernel after that. If you ever get stuck on the red Verizon screen, just pop the battery out and reboot.
That's about all anyone can do and a run down of everything.
Thank you for posting specific guides. I'll go back to step 1 and try again. The primary issue I have at this point isn't reading the guide and following directions, its finding the right guide to reduce the number of images I need to download. I'm on 1.5mbps DSL so d/l a 2GB file takes most of a day. I have several that don't appear useful at this point which means I've lost several days.

Understandable, I can't believe it is 2018 and we still haven't invented a way to compress 1.7GB into 1.7MB archives to make life easy on low connections. How is battery life on 4.4.4 and which update of 4.4.4 are you on? I've been having an issue with my phone dropping a percent every 2 minutes on 5.0/6.0. It would be nice find a version to root along with excellent battery life.
The reason I was looking at updating was due to battery issues. I had the phone for around a week before I rooted it (a couple years ago). After rooting, I started seeing immediate battery issues. My wife has the same unrooted phone (currently on MM) and has never had the type of issues I have. I figured the issue was likely a bad kernel and was thinking I'd just update to something newer (LL or MM) to help. I assume a new battery would help since mine is 1-2 years old, but I swapped with my wife's phone and she still gets lots better performance. Once I get this back up, I'll probably buy a new battery for each phone.
So it appears that I must have upgraded the bootloader to a point where towelroot no longer works as was previously suggested. I believe then that I need to follow the second guide to be able to downgrade to a rootable Lollipop version:
https://forum.xda-developers.com/ve.../guide-downgrade-to-kk-nk2-ncg-mm-lp-t3686858
I am downloading the PB1 rom and lolliroot and need to also get a system restore, kernel, and modem. As I said, my connection is terrible so it would be great if someone could suggest which version of restore I should go with. I was going to install Lollipop in the end (that was the original goal). I figured I'd just get OC4 since it's likely to have the least bugs and best performance. If that is a mistake and I should go with an earlier version of LL PLEASE throw it out there!
Ok, I tethered to my wife's phone and am burning her data (shhhh, don't tell her).
I grabbed all of the OC4 files, the PB1 rom, and lolliroot. I think I have everything I need so long as OC4 is a good place to end up.

Here are some files (that I been hunting for about an hour for). Just gonna reference this for future use and anyone who comes across this thread. http://rootjunkysdl.com/files/?dir=Galaxy S5
Nice find!
I have the phone up and running on stock PB1 currently. I'm going to let it sit to see what the battery is like prior to rooting. While I haven't gotten it hooked back up to my account yet nor do I have it rooted, I feel pretty confident now that I'm on the right track. Thanks!
Just to finish out this topic, I have not successfully completed attaining root on 5.0. I flashed PB1 to the phone and then followed this guide for installing KingRoot:
https://androidforums.com/threads/root-question.1120150/
I got the lolliroot files from here:
https://www.androidfilehost.com/?fid=312968873555011514
Thanks to all who offered help!
Qyuck question... I've got my phone working well bow, but there's one issue with apps I'm not sure how to address. I want to use Verizon Visual Voicemail but I can't find it on the Play store. I disabled updates so I wouldn't get the marshmallow update and break root. but, with updates turned off, VVM won't get pushed. Any suggestions?
Hopefully somebody can help me. I have an LG v20 h910 (att) that unfortunately was updated to most recent security patch. However I THINK I managed to downgrade with a h996 image following a guide here on xda. After that I followed dirtysanta unlock guide and instead of twrp I used the lineage recovery for the version I downloaded. Everything seemed to go fine but after the lineage boot screen it crashes. Something about the modem maybe. It's taken me all day just to get to this point and my phone is unusable so I'm really hoping someone can help. Please tell me what info you need sorry if I'm forgetting something my brain is fried right now...
EDIT: After a night of sleep I realize I didn't provide a lot of helpful information. I am getting a Kernel Crash (related to the modem I believe) when booting up the new lineage 18.1 image for my h910. I have seen other people mention these sorts of issues but no real resolutions. I am trying some things currently but if anyone has more knowledge I'd love to chat directly so I can get this figured out. I am new to this lower level android fiddling but I am a professional IT person and linux user so I should be able to figure things out with some basic instructions.
nevermind was able to fix by flashing the modem file suggested here https://forum.xda-developers.com/t/...ea-with-no-signal-alternative-kernel.3839170/
