Hello all, I have a Total Wireless aka Verizon TracFone branded S5, so it's model s902l but it's g900v hardware with unlocked bootloader. Of course they never released any updates so I'm wondering if some will share a twrp backup of the newest, or if you believe another is better, their modem and bootloader for me I'd like to try it, worse case I restore my backup if it doesn't take.
Thanks

As far as the Bootloader... you will need to be careful when it comes to that because you can permanently lock it up and, possibly, brick it too.
I'm not sure where any of the separate Stock Bootloader files are on the forum since those who, typically, need it installed back on the device normally just flashes the Stock Firmware via Odin.
I've got a feeling that you might possibly be referring to the Stock Recovery and not the Bootloader.

There's a handful of TWRP flashable ones in the OP of that thread.
The only reason that the thread title states "Odin" is because most of them are Odin flashable ones.
I'm one of the threads Developers and u planned on creating the additional Recovery flashable ones soon but, am just delayed a bit.
The Odin flashable ones are actually the preferred method for most members anyway because of the additional safety checks by Odin.

I'll look again but read on one of the posts that they weren't TWRP flashable? I don't have a computer to use Odin right now and last time I tried those very safety checks you mention prevented me from flashing 900v files to my 902l branded phone. Ended up with a read only modem for a bit for trying. Of course the only factory firmware available anywhere is older than what came on mine and what sounds like everyone else's branded phone so have to be careful. That's why I was hoping for a backup to try rather than flashing something, maybe I don't fully understand the process but thought it'd be a safer route?
Am I supposed to use one of the SS/FF zips?
Last time I was attempting to upgrade my bootloader and modem I was following a thread that was supposed to both upgrade those and unlock the bootloader of actual 900v phones. According to that thread SS/FF zips aren't compatible with TWRP because they work differently?
Well I tried the newest available zip, it took about 15 minutes to flash and said successful but baseband still s902ludu3aog2 so that didn't work... Still hoping to get ahold of a backup I can just restore it at least try, unless someone has another suggestion on how to get newer 900v modem and possibly bootloader on my 902l model 900v hardware?
So nobody is willing to share a backup of their modem and bootloader?!?!

I think, flashing a bootloader from another S5 variant is a bad idea, most likely you'll brick the phone. Prepare an unbrick microsd at least to be ready, but nothing is guaranteed.
I don't think you'll manage to flash modem and bootloader from TWRP because TWRP means Samsung's binary state: custom and these partitions are protected in custom state.
I think, your best bet is to revert to factory recovery, get Samsung binary: official, root the phone and use SS or FF.
Not possible, factory firmware doesn't seem to exist, only 1 does and it's older than what it came with from the factory. Also it's Verizon hardware, same FCC id, but different model and comes with unlocked bootloader. I don't want to flash anything, I just want to restore a backup.
I appreciate your advice but I already been thru all of this...
Flashing is simply not going to work unless there's a way to change my device model maybe?
All I really want is somebody with a modem and bootloader newer than KitKat to please back them up in TW RP and share them please.

If the hardware is physically identical I don't understand why running a bootloader meant to run on this exact Hardware would cause a problem?
But I'm primarily interested in an updated modem. Neither will Flash since there are no updated modems for this MNVO branded Verizon phone.

I'm trying not to clutter up the forum with questions, but I'm not having any luck fixing my issue, so I'm just weighing my options... I've backed up my aboot for my dev edition G900V... because it seems I'm going to have to flash stock firmware/tar in order to see if my LTE hardware is jacked up, since NOTHING I do has restored my access to LTE. I had access when I was on stock rooted NCG, but lost it since I backed up my aboot and flashed NI2 firmware after deleting aboot.mbn from the NI2 firmware. So, my question is, if i flash stock NCG firmware with an NCG based ROM, how to I restore my unlocked bootloader from my original backed up aboot file?
Yes, I'm in over my head, but don't have much of a choice at this point. Thanks for any help!
I believe you can do a factory reset on the Dev Edition
Without fear of locking your bootloader. It should return to it's original factory TW state, with unlocked bootloader, as new. You would obviously lose any personal files/apps not backed up on a card or other device that are not stock. Good luck.
Do a search for backing up the aboot and pm or ask in the thread to the specific users that were dealing with that. You may only have one shot at getting this right...

That's why I'm worried... I actually did PM the OP of that tutorial, but I have yet to hear back from him. I was hoping some other dev might have some insight on how to restore that backup , but no one has replied yet. Thanks for the input though!
All i get now is a bootloop. I have tried flashing back to the nk2 firmware via odin but then it kicks me straight to recovery. It isnt the custom recovery though, so i think i may have locked my bootloader. Is there anything to be done from this? I usually can find my way out of this stuff but I feel like a just wrecked my galaxy s5.
You flashed a retail firmware which locked the bootloader. I'm pretty sure you made a $600 paperweight. Sorry I'm not much help.
Did you backup your developer edition aboot?
I've gotten no help at all with this. Very unlike this forum. My phone is a kltevew, which is straight talks version of a g900v. I need help, there are lots of great looking Roms that require you to have mm firmware I'd like to try!
Not sure why I'm getting g no responses on this. Surely someone must know something... The only response I got was not only not helpful but jerky and obnoxious. Doesn't anyone know how to upgrade the firmware on my phone? (And no, google has no answers for me on this.. I look everyday)

Download it with samfirm http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 (Model= SM-G900V Region= VZW) or from sammobile http://www.sammobile.com/firmwares/database/SM-G900V/ , do you know how to flash firmware with odin?
I do. Thanks so much for responding. Every time I try with Odin, a few different releases, it always gives me the error message fail. Can it be done with flashfire?
What stands in the log of odin when the flash completes?
Ill have to do it again to see... Be back in a bit!
I think it says FAIL! modem but I'll have to run it again... Brb
Last night I used flash fire to install firmware. That didn't get past the red Verizon logo, so I put twrp on it with Odin. Twrp showed it as dpd1, but it just wouldn't boot. So I wiped it once and flashed a ROM that requires mm firmware. Same thing, justbootloop. So I put stock back on it, then mokee 6.0.1. which works, I'm just not on mm firmware and all the great new roms are still unavailable to me.

Have you enabled the option to flash bootloader on flashfire setting?
What? No, I haven't... but do do right now. Thanks for the tip! Actually, where would I find it?
So would I do it in this order? Flash the dpd1 bootloader, then modem, them rom, then jrkruse patch? All in flash fire?

It's in setting of flashfire...but only do it if odin doesn't work because do it from flashfire is more riskiy...
1)do a backup
2)check the bootloader flash option
3)install the firmware with all the wipe except internal storage(it mean that flashfire delete /data excluding /data/media/0 (sdcard) but include it in your backup copy because you never know )
4)wait till reboot skip setup wizard "spamming" the next button then install the rom with flashfire or twrp
On the flashfire site i found this:
Flash bootloaders
"This setting controls if FlashFire will attempt to flash bootloader partitions. By default, bootloader partitions are only read and never written. Even when enabled, flashing bootloader partitions may not succeed - many devices have protections in place against the bootloaders being overwritten.
Please note that flashing bootloaders is extremely dangerous. Any bug, error, or failure may result in an unrecoverable hard-brick. Do not use this feature unless you know exactly what you are doing.
Due to the danger of this feature, it is automatically turned off every time FlashFire starts. You have to manually re-enable it every time you want to use it.
If you must flash bootloaders, it is advised to use a bootloader-based flashing tool such as fastboot or ODIN to do it, as these are the safest methods. OTAs may also update bootloaders, and though slightly less safe than fastboot/ODIN, it is still much safer than having FlashFire flash bootloader partitions directly."
So i suggest to try to flash the firmware directly from odin first

Redownload the firmware extract it again,factory reset your phone,and try to install the firmware,maybe it's a bad download
Should I be flashing a kernel too? Will it even start/boot without the right kernel?
find out if you phone is refurbished. to install stock ROM you would need the main board and boot to be the same model.
if it's not, then you just need to install bootloader/modem without full ROM. look around in xda for bootloader/modem.
I just upgraded to the latest G935FXXU1BPH6 using Odin (v3.12.3). With past firmware releases, I was able to load TWRP twrp-3.0.2-2-hero2lte.img.tar using Odin and then proceed to root the phone.
However, with BPH6, TWRP refuses to boot. I try the volume-up+home+power sequence but TWRP recovery never starts. The phone just sits there on the boot screen.
I'm able to recover by re-flashing the BPH6 firmware but this leaves me thinking that the bootloader has changed in BPH6 and twrp 3.0.2-2 is no longer compatible.
1) Anyone else having this issue?
2) Any solutions or workarounds?
3) Do people think it would be safe to dowgrade the bootloader or entire firmware? I'm willing to try it but I'm a little concerned about bricking the phone.

In Odin flash an older firmware then reroot and wait for a root update from Chainfire and the TWRP team
I know a couple people that have done that.
"And on that bombshell!"
Sent from my Echoe powered AEL Driven G935F
When I first upgraded to the new firmware, I found the same thing that you did - I wanted to be able to flash custom roms and didn't know when or if TWRP and ROOT was going to be possible with this new firmware - so I used odin and reflashed July's Firmware and I was able to do so without any Issues - so then I decided to try to upgrade the AP/CSC/CP files from the latest update and replaced the bootloader with the bootloader from july's update and it worked.
Good luck - frankly I am Concerned. It appears that the latest bootloader from Samsung is LOCKED - I only hope someone is able to get root and twrp working - and I hope this is not an indication of future issues for rooting samsung phones....

No it isn't. Korean models had already been incompatible with official TWRP since firmware APG7 and I confirmed it working again when I replaced the kernel inside TWRP with one built from the latest source released by Samsung. So, someone needs to build a new TWRP recovery with BPH6 kernel source and everything will become fine again.
I didnt know that but it is very good news as far as I am concerned.
I have alwasy been fearful that Samsung was going to eventually lock down their international phones like they did to the US Variants - and when this originally happened to me, I started thinking that maybe my worst fears had come true. Thanks for the information....

When flashing bootloader in Odin there is an options tab, there are checkboxes - Auto Reboot which is checked - Re-Partiion which is unchecked - and - F.Reset Time which is checked, I flashed new bootlaoder and modem and now my phone will not restart no matter the key combination I press. So Are those checkboxes suppose to be checked off or unchecked
I have a Galaxy S5 (Verizon) SM-G900V that's running stock rooted Lollipop. Safestrap is on here, but yes, the bootloader is locked. Other than going to Marshmallow (and losing root), are there any custom ROMs (I'm looking for speed and stability) that this phone can take? Or am I stuck with stock, which means I'm stuck with Lollipop if I want to stay rooted?
My choice is this one without root for CID11 or full-featured systemless devbase for CID15.
Thank you. I assume I use safestrap to install on my rooted stock CID 11, but on this new one without root won't be able to restore apps from Titanium. Are there any other alternatives an 11 can use and keep root, and if I try one can but change my mind can I restore a backup in safestrap to get back to rooted stock?

3) if I have a SS backup of my stock lollipop and don't like phoenix (which seems to be MM) can I restore from safestrap back to my stock LL? Or could I just re-install the stock LL image?
4) can I/should I update the modem in this process, or does the locked bootloader prevent that?

You'd better use a single thread for similar questions. There's a nice SM-G900V section too.
1. Yes.
2. You're limited to a stock signed Verizon-Samsung kernel, not to a stock ROM. You can (in theory) install any ROM that can use a stock signed Verizon-Samsung kernel but even a kernel from SM-G900F will not work.
LOS uses it's own kernel.
TWRP uses it's own kernel.
RR uses it's own kernel.
Root on 6.0.1 and above needs kernel modification.
These won't work.
If Phoenix can use a stock kernel (I don't know), it will work.
3. You may want to have a look at this thread: https://forum.xda-developers.com/verizon-galaxy-s5/help/getting-safestrap-loop-t3601977
I don't usually do it myself but it should be possible.
It's not an easy way and there are some logical traps on it.
So think it over before the action.
4. Locked bootloader does not prevent modem updating. It's definitely possible. You can simply flash a modem part of stock firmware in Odin.
Thanks. I've tried casting a broader net, unsure if my problem was Verizon-specific or not. Turns out, it's even more specific than that, as at least some 900Vs have unlocked bootloaders and some (mine) don't.
As I look back over my journey, you were there from the beginning when I was trying to upgrade from 4.4.2 to my current Lollipop and keeping root. Following the steps of the amazing @jrkruse led to different problems, which still persist. There seems no way to fix that, from which I conclude the jrkruse stock ROM and this phone don't get along. Hence, the idea to try a different ROM other than this LL. It seems that my locked bootloader has me on stuck on this particular stock ROM if I want to keep root. There is no list of other ROMs I can put on this CID11, and I'm not sophisticated enough to know which I can try and Safestrap back safely if things aren't wonderful. This has me doing a hot reboot every day or two when I see wifi can't get DNS, but I don't see any other option other than buying a newer Galaxy with a microSD card and an unlocked bootloader (maybe the S8?). Regardless, this sums up my journey, I've learned a lot along the way, and both you and @KazuDante were extremely helpful and earned my Thanks button many many times. Thanks again.

ps: I read the first ten pages of this thread about modems, but the first post strongly implies that they're not flashable with all the crossouts, which leaves with Odin, but if I'm reading it right one needs TWRP, which I don't have, only safestrap.

androidman807, which firmware (modem, kernel, bootloader) do you have and which do you want to have?
P.S. "Odin: (necessary for those with TWRP recovery)" means that a phone with TWRP has "Binary status: Custom" and there's no other way to update modem except Odin.
Baseband : PB1
Build : PB1
Kernel : 3.4.0
At this point I'll take any rooted firmware that is stable and not sluggish with this phone, with ability to at least get back to this if it's a step backwards.

I think, if you have network problems with this phone, it will be the best to backup your data and try a factory firmware with full factory reset.
If you're currently on BPB1 you can try any firmware above (and including) BOK3 and return back to BPB1 if you don't like it.
Firmwares BOK3 and BPB1 (your current) can be rooted after installation.
If I remember correctly, you need root to use Titanium backup app.
But you may want first try if the network problems persist on different stock firmwares.
I'd begin with the latest - DQI2.
Titanium is a big reason why I want to keep root. So BOK3 and DQI2 are ones I can root and still return to PB1. Thanks, I'll start looking for them and their rooting procedures.

You can flash modems using odin even if you dont have twrp , they made it that way for those who are not on stock firmwareand that have twrp for example those who are on nougat , instead of flashing back stock and redoo the whole thing all over again , so in the vzw section there is a thread that has all the latest modems ( i think qh2) , just download qh2 ( i used the non-hlos for 4g) and in odin use ap and select the downloaded tar(modem) and flash , phone has to be in download mode.
Thank you. I was hot on the modem idea when I was going to switch to Lineage or something else as a natural step. But since it's tied to 4G and cell service and not my sporadic DNS-on-wifi issue, I'm not sure I see the benefit, but then I could be wrong. I figure a different ROM will have different drivers for the wifi radio and solve things. At least that's been my hope all along.

Thanks again - I flashed with Odin the DQI2 I found but didn't know how to root it (Safestrap erased and no TWRP). Maybe the answer is the same as the other post I just replied to. That's obviously a blind spot I have that has me stuck on PB1 - I don't know how to root anything else on this CID 11.
