[Q] Which modem / bootloader?

Hi Guys. I recently sold my HTC One M7 for an LG G2 and never looked back, so I'm hoping some of you guys/gals could help ease the transition. I got this phone already rooted and since then have installed the latest build of CM12 Lollipop. I want to flash a new kernel but have read that certain kernels have to have certain modems and/or bootloaders. So my questions are :
How do I find out which bootloader i'm running
Which modem should I be running with CM12
Which bootloader do I need
To fill in the rest of the blanks, I'm running an AT&T D800 and would like to flash the Render Kernel onto CM12 Lollipop. I'm also currently running a KK Modem, is this correct? Lastly, I do not know the method the original owner used to root. Thanks in advance!!

need modded xt905 Aussie NON-HLOS for xt907 kk

i need to unlock lte 1800 band (as available in xt905), so i need modded xt905 Aussie NON-HLOS to flash on my xt907 (cm11 kk bootloader)
can any one please share it... existing dropbox and google drive links are not working...

I wouldn't try this as it will brick the phone. Reason: different Trustzone signatures. There are / were peoples attempting to flash different NON-HLOS modem BIOS for the particular RAZR M (for example, XT907 NON-HLOS onto XT901. The result is pretty obvious: dead as a doornail). I am researching on RAZR M unbricking and I can pretty much tell you mucking around with the BIOS (bootloader) is a big NO-NO.

I guess you can flash the complete XT905 firmware on the XT907. It did work for me and even the modem does work for GSM (no idea about LTE or CDMA though). It's just, that there is still no KitKat available, so a CM jbbl version would be needed.

I suppose you can - just have to have some confirmation so you can be sure you won't brick the phone you spent the hard-earned money on.

thanks alot,
is this the version that i should flash? and since im currently running cm 11 on kitkatbootloader does it support downgrade to this stock?
9.8.2Q_SMUIRD-7_SEMEAUnlk_USAXT90501TLSTRAE1019.0R_SMJBLTEAURETAIL_P008_A014_1FF_fb.xml

I don't know about the version number. I was on the first VZW KitKat (*.10) and flashed the latest available Aussie firmware which still is 98.21.7 (Build 9.8.2Q_SMUIRD-7) dated Jan 9, 2013.
As long as you have an unlocked bootloader, you can downgrade to JB. There are just some lines in the XML that have to be removed (GPT, TZ, and maybe something else if it fails - the usual procedure for downgrading).
Here are the official CM11 builds for JB bootloader, most likely there won't be any for CM12.
Edit: I was wrong about CM12 for JBBL. Obviously there will be builds for this older bootloader too.

OK2, Android 5.0.1--what are my options?

I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!

There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.

Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.

Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.

The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.

Upgrading lp to mm, now I can't install custom roms

Don't Know what I am doing wrong. This is my forth phone I've rooted and installed custom roms. I just upgraded from lollypop to Marshmellow, I was running moar rom on lollypop, no problems.
After I upgraded I lost root access so I re-rooted. But now I can not seem to have success on installing a new rom, I've tried two different roms. I follow the instructions and it begins to load and just sits there, even after a good 20 minutes or so. I'm figuring I'm missing something here, please help. My stasts: ,Sprint carreir, model sm-G900P, build MMB29M.G900PVPU3CPCA

You can't flash lp roms anymore since you have mm bootloader and modem

Duh! That's why i said he can't flash lp rom with mm bootloader and modem.

Ok, sorry for being such a dumb ass, but can someone walk me through this. I only know enough to be a total danger to myself and don't want to really f something up that I can't fix.

Seeking KitKat SBF for XT905 (preferably Australian / Telstra)

Hi All,
I am looking for a KitKat based SBF for an Australian (Telstra) XT905.
If anybody is in a position to upload / share such an SBF that would be awesome!
Alternatively would it be possible to use an SBF from a different carrier, e.g.: Verizon, and then downgrade to the JB SBF that is already available.
My kernel is stuck at KK, but everything else is JB > this occurred because I used OTA updates (to KK) before 'zigging instead of zagging', long story short I just need to install some form of KK onto my XT905 (even if that means downgrading later!).
Any help here would be greatly appreciated.
Kind Regards,
Davo
