Some time ago, I managed to unlock the boot loader on my Verizon Note 3, then flashed a newer TWRP recovery, and Temasek's Android 5.x ROM. Like others, I lost GPS at that point, and some other functionality. I shelved the phone for a while, recently pulled it back out, and updated it to Temasek's 12.3 ROM based on CM13. I still don't have GPS, and have been trying to roll it back to a prior version of something to get the GPS working again (like the guides I've found here on how to fix the GPS issue), but it seems like anything except the 2 Temasek ROMs I have fail out on install now.
The extra hard part for me is that since it was so long ago that I was messing with this phone, I'm not even sure what I did back then as far as what specifically I did to unlock the bootloader, and what recoveries I was using, so I'm not even sure what to search for now to figure out how to roll this back. I was fine even on KitKat, and only tried to get it running a newer ROM for one nav app that required Android 6.0, but if I don't have GPS, a nav app is pretty pointless, lol.
This is the wrong forum if you have Verizon model.

Flash odin to stock. I've heard that's is the easiest and fastest way to recover GPS capabilities.

Hi there,
Happy owner of a Nexus 4 runing stock ROM with Android ver. 4.4.4, I rooted it few days ago with Towelroot app and unlocked the bootloader (with BootUnlock app) in order to enable the LTE fonction. I dit it with LTE Nexus 4 Modem Flasher app and it works well (my mobile carrier uses AWE for 4G). The custom recovery TWRP has been installed by the app prior to allow the flash of the modem driver/firmware. Now I am wondering about the coming update Lollipop which I really want to get.
As I could read in the forum, even if the system offers me the OTA update option, I should decline it since my custom recovery has been changed. Am I right? I have a doubt because I also read that people successfully updated OTA their rooted Nexus 4 even before Towelroot was existing and I guess this imply that they necessary changed their revovery...
As you may understand, I'm a bit newbie, I just rooted my phone and unlocked the bootloader without using the toolkit, and ideally I would avoid to do so.
My main concern is the following: updating to Android 5 (stock ROM either fron OTA or the tool kit), will I lose the benefit of LTE, or in other words, will the update change the modem firmware/driver?
Nota Bene: I don't really care about loosing the root privilege but I want to keep the LTE capability.
Thanks,
Guillaume.

I honestly can't speak for OTAs, as I've never done one on my Nexus 4. When I got mine, it already had 4.4.4, and I've been using custom ROMs since, and never back to stock.
But I can tell you that the radio survives ROM flashes, so I suspect it'll survive flashing the official 5.0 Lollypop ROM. You don't need to do an OTA to upgrade stock ROMs, you can flash them from recovery. You just have to wait until Google makes it publicly available and someone makes the flashable zip, or you can do it with your computer and ADB. I won't go through the steps here, since we haven't gotten there yet.
Regardless, even if it's not immediately, you will be able to update to 5.0 and have LTE, but wait on accepting an OTA or flashing until it's clear exactly how it'll all work.

It occurs to me that people have been using the ported L preview on their Nexus 4s for a few months now. I haven't tried it, but maybe one that has could help you better. I'd search, but the L preview thread has 16000+ posts in it, and I'm just not that interested enough to try (I'm probably sticking with KK if/when Xposed works with ART).
OTA's often replace the modems, and since it can replace the entire /system directory it could potentially disable LTE enabler as well. And flashing stock images will replace your modems, and everything else in the phone like recovery, with the stock ones.
If LTE is really important to you, stay with what your using and do not OTA... wait until the new Lollipop radios are modified as a hybrid, then flash the stock Lollipop ROM, flash the radios and enabler, and you should be good to go. This is assuming they don't do something to break the OS so that hybrid radios are not possible.
Also, since you are on custom recovery, NEVER take an OTA... EVER... it will soft brick your device (it will be recoverable, just takes some work).
Personally, I was LTE for a while, and it was very hit and miss... would often drop to 3G and not go back to LTE unless I toggled in/out of airplane mode, and it destroyed my battery, cut my screen time in half. When I was on LTE my average screen time was 1.5-2.0 hours and I could not make it through a 16 hour day on a single charge, now that I removed them and want back to the stock 3G 1.03 radios, I get 3.0-3.5 hours screen time over 16 hours and it makes it though a full day, usually without a bump charge.
I ordered the AT&T unlocked S5 Active off Swappa from a seller that resells phones from corporate usage. It came with 4.4.2 and some modifications that lead me to believe the company does did not permit upgrades. That said, it was hell to get MTP working on it and it did not read any microSD cards (yes I troubleshot plenty). They offered to replace it and so I have a Verizon S5 (not Active) on the way instead, as I'm hoping for more official upgrade support (Marshmallow this month??).
Aaanyway, regarding root, updates, tips/tricks, etc, any suggestions?
I'm coming from the AT&T Moto X 2013 but have a good deal of experience with roots, mods, etc.

Honestly, it's a very easy procedure I was hunting and hunting when I got mine (about a month ago) so I've done plenty of research.
Mine had 4.4.2 on it as well. There is a downgrade process which is fairly simple and straightforward. It requires using Odin. I also followed a thread here http://forum.xda-developers.com/galaxy-s5/general/tut-root-tripping-knox-t2803951 which helped me a lot. I also read that towelroot isn't working, so I found one set of tools which has towelroot plus v2 and v3. v3 worked for me the second time. Try googling some stuff, there is tons of information, I'm looking for a good ROM or at least a pre-rooted updated stock ROM. I have version 0A8, which is the first OTA lollipop update. I'm looking for a ROM based off of lollipop there are tons based on kitkat kernel thou. CM is working on I think 12.1 So I may downgrade again because the downside to having Verizon lollipop installed, TWRP will no longer work. Stay with kitkat, install TWRP, and go from there, think I'm going back to kitkat to find a decent ROM, I like having recovery. Hope I helped a bit

Helped a ton I was thinking of sticking with the Active so I wouldn't need a case, but with all the development here, I'm glad I switched. And the Verizon model seems to be doing better than the AT&T one in terms of OTAs.
I was on a 4.4.4 for a long time as OTAs lock bootloaders.
I am happily rooted on 5.0 running a TW stock rooted ROM.
Beware of OTAs..... they can kill you. LP is Def better!

Sry about the terrible shorthand. Finally broke down and factory reset my verizon gs5. Before setting up i decided to roll it back, root it, and get a debloated PB1 rom from here:
https://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370
So, if like me, and you have the nov/dec VZW OTA update on your phone PJ2 if i recall, this link got me rolled back and rooted. This method added busybox which i didn't really understand, safestrap which i actually kinda liked, and initially kingroot then the flash went to superSU.
I kinda liked the marshmallow os a touch better with the google now launcher and everything verizon as removed as possible vs 5.x.x. Basically the verizon OTA update to marshmallow essentially bricked my phone (not enough space after like 3 years of never re-formatting). I love my tablet that essentially runs just a bare bones no BS google android marshmallow software similar to what a pixel has or nexus had.
Doin more reading looking for such a rom i found this link:
https://forum.xda-developers.com/ve...t/rd-unlocking-galaxys-s5-bootloader-t3337909
This successfully unlocked the bootloader. They omit that you should make sure you have the rom on he phone or sd card before starting. So before using odin make sure the rom is on the phone and matched the bootloader unlocker you wish to use. This method of flashing used TWRP recovery which i found to be...different than safestrap but functional all the same.
QUESTION 1
Is there a rom for the SM-G900V that is similar or identical to a non branded google device like how the pixel comes stock?
I haven't messed around with the phone since unlocking the bootloader and flashing it to the VZW_BPB1_ODEX_DEODEX_V9 using the TWRP Recovery. Basically if my best bet is a debloated stock but rooted vzw rom that is 6.x.x and then manually removing/deactivating the garbage from vzw apps i'll do it. But figured this was the place to ask if there was already a rom out there that works on the SM-G900V. Because i can easily put a rom that does the job instead of tinkering more than i have too.
QUESTION 2
Now that i used the SafeStrap_PB1_Bootloader_Unlock_AIO.zip and flashed VZW_BPB1_ODEX_DEODEX_V9.zip using the method from the second link. It APPEARS i can just load a 6.x.x rom and use TWRP Recovery to flash that. Am i mistaken? Will i need to do the unlock bootloader process over for the PD1 PF4 or whatever boatloader unlocker corresponds with the rom. OR...now that the bootloader is no longer verizon'ed can i basically swap roms to my hearts content as long as they do not also try to install a new bootlaoder??
I have no idea how to "tag" either poster from the links i mentioned but i'm certain many here as well as they could answer both questions easily.
Hey I haven't been rooting in awhile because I just been to busy to really rest new features and whatnot I've just been using my device as your average consumer. But I just got a note 4 for a very sweet deal and want to get back into rooting. My phone is unlocked on metropcs it is a tmobile model that's fully updated with the latest firmware and stuff. I just would like to get a decent bloat free touchwiz rom because I would like yo use the fingerprint feature but every touchwiz rom I try flashing doesn't work. I haven't tried cm 12 yet. Can someone point to the right direction please just want a simple rom with touchwiz main features not even all of them lol
What recovery do you have? You should be on last TWRP 3.0.2 and also check your Bootloader and Modem if you need to update them with ODIN.
I've grown tired of the increasing instability of this rom and the myriad data/voice issues with crazy outdated prl. I was going to flash the latest stock oreo from sprint/samsung but when cruising around I noted a post talking about flashing back to stock from root and it not working properly because of the 'verity bit' depending on the rooting method. I went thru the instructions post for my current rom and can't discern if that would be an issue for me. I've only got a couple months left with the phone before upgrading and just would like to be able to have everything work consistently.
suggestions about how to proceed? i had tried to use the samsung smart switch just to see what it would say, it recognized my phone as a g930u not p (obviously)
