[Q] been a couple years so forgive me - G2 Q&A, Help & Troubleshooting

Hey guys... it's been a while since I've been on XDA.. I can't say I'm much of a developer anymore so bear with me as I work 2 jobs and don't have a computer anymore to do ultra fast searching..
So I'm looking to root my VZW LG G2 on 4.4.2 but I'm running tmobile.. I'm not looking to run AOSP, if I was I'd already know the answer to these questions... I'm looking to flash a G3 port, any reccomendations? And on these stock roms what do I have to do to get my baseband working for tmobile? I read that optimusg3 would work on the vzw variant with the vzw baseband flashed, but is that necessary with me using tmobile? Would it be better to just flash a tmobile baseband? I'm not used to these multi-carrier phones... BACK IN MY DAY SONNY WE HAD DIFFERENT MODELS FOR DIFFERENT CARRIERS LOL.
Final annoyance if someone wouldn't mind making my life easier and provide a link for a tutorial of rooting with kit Kat that way when I'm in front of a computer I'll be able to get right to work without going search crazy..
Thanks all!!
I'm glad to be back!!!!!

You can root and install safestrap, which is based on TWRP. The bootloader is locked so non-stock ROMs like CM11 or anything Lollipop based is out of the question. There are some good stock based ROMs though.

[Q] Help regarding SM-G900P

Hey everyone, I been looking around the forums here and other sites and have learned a lot of info in pieces but I really need help with a particular issue. A friend of mine gave me a Sprint Galaxy SM-G900P (Galaxy S5) which is (of course) CDMA with GSM compatibility. Im unsure at the moment what service he was wanting to use but I know it is a GSM carrier (US) because he has a SIM he wanted to use. I owe him a favor so I told him I would try. Besides going the route of purchasing a unlock box and unlocking the phone with that, I discovered the SSU apk which SIM-Unlocks the phone. I downgraded the phone from Lollipop 5.0 stock to Android 4.4.2 KitKat (G900PVPU1ANE5) with ODIN. (FYI, i was stuck in download mode with no recovery mode for a week before finally getting one to work, and so happen to be that version that went through)..... I downloaded SSU and it unlocked the phone and I switched mobile network mode from CDMA to GSM Units. (NOTE: it says 4.4.2 and up will not work with USA carrier SIM cards without downgrading the Modem but I have not tried just yet) Im about to Root the phone but here is where my question comes in. I have read of people flashing roms to get their phones to work with certain carriers and other functions. Will rooting help me out at all? I guess IM asking if there is a ROM that I can flash onto the phone to enable the use of whatever carrier he is wanting to use with it. I know thats most likely useful in the situation, but Im awaiting that answer as we type. ANY help would be greatly appreciated ))) Thank you all.
Anyone? :/

Have an Unlocked Model Using it on T-mobile Network Was Said To Ask Here

Well first of all i have an SGH-I337 Sim Unlocked and am using it on the T-Mobile Network. Now I have been told something about a locked boot loader and other things but in all was told to ask my questions here. I am posting this because I want is to root this phone and use touhwiz roms. So to Make this Short as possible. Can anyone link me to any threads (as i know this has been talked about) and tell me what they are for and how to root and rom this phone. I only have experience with the TGS3 on the tmobile network never have i used a phone unlocked from another network and I would love to update this little guy as its an upgrade for me from a gs3 and right now the software are both kitkat.
The phone is An ATT SGH I337 unlocked on the T-Mobile Network
Its running NJ4 Stock
Any questions i will surely answer I hope to figure this out and pimp my phone, jk just make it an upgrade from my sg3 with kitkat so looking for lolipop. I have been told this model has some issue with asop roms but i dont care personally i like touchwiz cause most aosp software seams to be missing something IMO and takes at least a year to be stable i dont care if people say its a touchwiz clone I appreciate new features that work.
TYIA
Read this first: [GUIDE]Odin to Stock, Updating, Rooting, and Installing Safestrap
Then read: Everything you need to know about custom roms.
Then if you have questions, ask.
Thank you i truly appreciate you giving me where to start thank you for the quick answer and hopefully i wont have any problems!!

CM13 on Cricket (post AT&T merger)?

Hi all -
I posted this question on CM forums - they suggest I also try here - I have a Cricket Galaxy S4 - post AT&T buyout. It is a GSM/LTE phone using CM11 and a Cricket SIM card. I was wondering if I am limited to CM11, or if I wanted to upgrade to CM13, would I just use the current jlfteatt builds? Anyone out there in a similar situation?
Thanks!

What's the exact phone model?
Since it already has CM11 you should also be able to get CM13 on it.
Both the "about phone" and sticker behind the battery say SGH-I337. Sorry for being noobish about it, but is that what you are referring to? I know the S4s cell in different flavors, but otherwise I just think it is the garden variety S4. I guess my main concern is all the talk about the basebsnd versions. Mine doesn't match exactly, but not sure if that is just about rooting the phone. I am of the same mindset that it should work if I have 11, but I can't afford to brick my phone just from a time perspective (never mind money as well ) but I want the shiny upgrade sooooo badly....?
Thanks!

There's nothing you can do about the basebands and bootloader. If you update them your device might get locked and no custom roms or root can flashed anymore.
Sincthe the phone already has CM11 I assume it isn't locked. So just flash a newer recovery (TWRP) and flash CM13.

Google Android 9 Rom to ATT Android 10 Stock Rom

So back when I got my phone in Feb 2020, I did what most people do when they have a new device, update it. After some googling, I found plenty of threads about how great the google version of Android 9 is for the v35. Removing the ATT bloatware was my main reason for flashing to it.
I've read on a few different websites that if you flashed to the stock google android 9 rom, that there is no way to flash back to the ATT roms, or upgrade to the current android 10 att rom. My phone is unlocked and is of course, the ATT version.
Model: LM-V350AWM (doesn't show that it's google I guess)
Hardware: Rev 1.0
I have not bought an ATT sim card or gotten there service to upgrade because of what I read. Is it possible to flash back to stock ATT ROMs or to OTA with an ATT sim if I flashed to the google version? Anyway to go back (stock 8.0 even)? I really don't want to switch to a new phone since I got this baby for 190$ and finding something equally good or better in this price range is not happening. I'd appreciate any information you guys have on this.
Thanks!
It isn't clear from your note what you want to do. If your objective is to get to A10, I highly recommend following cloud's guide to localize the Korean A10 rom. That would require unlocking the bootloader. Everything on that rom works at least for me and my use cases. Browse around here in the v35 forums and you'll find the threads you need.
If your aim is simply stock A10 with ATT, there is one option. Someone posted a partition dump. You could try writing partitions one-by-one usind qfil. I haven't seem any reports of anyone doing that....
Okay. So is it confirmed that if you flashed the stock Google Fi Android 9 onto your att phone that you can't flash back to atts? Different partition sizes end up bricking the phone? I can't find any att kdz anyway. Not even the older android 8. I know att $oesnt release theirs but plenty of folks normally upload their stock kdz for the community.
Really confused with how dead the LG V30/35 community has been since day 1. I remember when I was learning how to root my viewsonic g tablet and galaxy 3 (2011-12) the forums were bursting with people and stock kdz loaded everywhere. And 30 different roms were being worked on for one device. I think the galaxy S5 community is still more active than this one. Smh
Thank you for the reply. I'll look for the post you mentioned. I haven't worked or played around with modifying android in 10 years. Only thing I've done is a quick flash of googlefi kdz back in 2020 which was brainless. Just looking at the tutorials to root this phone seems daunting now lol.

AT&T does not release kdz. Don't know why you think that needs to be confirmed. Partitions for AT&T A10 have been dumped. You can write them one by one by qfil.
As to why V30/V35 development is dead, a huge factor is that lg exited the mobile phone market. LG, despite making good hardware, was also not developer friendly. The V35 is 4 years old.
As for rooting a V35, just follow the instructions if that's what you want or move to newer models with 5G, more memory, and greater battery capacity.
I am still rocking my V35 Fi phone happily.

I thought people who were more tech savvy than me could pull a stock KDZ off their own ATT phone. That's what people did in the past anyway (I believe).
The phone is still great and I'm glad you are happy with it. I just wanted android 10 on my phone. Stock. English. I might try the Korean route since I'm less likely to brick my phone. Who knows, we'll find out. Thanks for the replys.
The localized A10 Korean rom has been fantastic for me. Everything works.
Make sure you backup ftm and efs partitions before starting. You will lose the S/N but it is easily restored. If you are in US, I suggest you flash the localized OP partition. Links are in the localization thread started by cloud.
