Marshmallow of GS4 GPE, IS IT SAFE? - Upgrading, Modifying and Unlocking

Hi guys. I found this ROM but it doens't give any detail of the GS4 models that are compatible to flash it. Here is the link so you can verify by your selves http://best-tech-reviews.com/jflte-gpe-android-6-0-marshmallow-rom-for-galaxy-s4-9531/
I have a GS4 SGH-I337M which is known as Canadian Model (I bought it on Mexico). Now the device is rooted and running @devth GPE 5.1 Lollipop ROM JFLTECAN with almost no problem, except that the dev has no time by now to keep updating the ROM (he even make his own OTA app that was amazing when it was working).
As I don't know any person who has flashed a Mashmallow ROM on a GS4 I really want to learn about any risks or specifically: which devices are compatible with the ROM menctioned at the provided link.
Excuse my english and please, have a nice week! :highfive:

4.4.2 International Roms

Will I be able to flash 4.4.2 international roms on my phone, I can flash the 4.3 with no problem, but I'm not sure if the 4.4.2 will work on my phone. I would like to try this one out. http://forum.xda-developers.com/showthread.php?t=2472301
Thanks, any comment is appreciated.
From what I've read recently we need a kernel before our phones will run 4.4.2. I can always be wrong since things change daily

Do not flash anything with a bootloader! You will be stuck.
I wouldn't try any of the 4.4.2 TW builds from any other device at this time. Wait for someone to Port and have a good working kernel for our phones.
It's so difficult to see kitkat roms for many other devices and nothing for us. We have to wait till there is an official or leak of T-Mobile version of kitkat to have anything started. Just hold back guys. This is not going to be late...

Yeah, its really annoying that that even AT&T has a leaked version and we still cant use that. There arent even any devs working on a kernel, seems like everyone is just waiting for samsung.

[Q] [q] Bell OTA + Lollipop + Custom Roms

Hey! I've been spending hours reverting my rom to stock and doing my OTAs to get to lollipop.
My phone is a Bell M8 with S-ON. I am currently up to 4.4.4 and about to do the Lollipop update. I am aware I should do sunshine on 4.4.3 but am broke right now so was just thinking of waiting until it works on Lollipop.
That being said, the current Bell OTA for Lollipop is version 4.20.666.1 (awesome numbers btw) and most roms say I need firmware 4.16.x.x.
My question is, will those roms work properly on this firmware? Or should I go back to 4.4.3 and use sunshine (I am impatient and want lollipop now, but stock roms suck.)
Thanks for the help!
edit: I found this advice in a rom thread
In future Rom releases, you may stick with your region’s firmware as long as that firmware is from the current released base, such as 5.0.1, 5.0.2, etc.
Firmware flashing is not required for every Rom update. Most of the time it is best to remain on your phone’s native firmware for best signal reception, battery life, and overall performance.

So does that mean as long as the rom is the same version 5.0.x that I should be fine?
Ya you should be fine tuning that firmware with the Rom... Can I ask you to also please upload the ota for us ...I've been looking for it all around

Where do I find it I haven't update yet.. I'd you can tell me where it is located I can extract and upload it.
I have a TWRP backup of it. Would that work or probably not since the firmware isn't there.

[Q] Sprint G2 ROMs HELP!

Hey Guys,
Hope you guys and gals are doing well. I wanted to know if there is rom for LG G2 (LS980) the latest build without the sprint bloatware? The current rom installed is "ZVD" but the knock code doesn't work and the software update option is missing. I got this from a friend and I am guessing he didn't flash it properly.
so I want to know the following things:
1. Can someone or has someone worked on the ZVE rom and removed the Sprint bloatware, If yes can someone please share it?
2. Is it possible to flash a D802 rom over LS980? I know noob question but still
3. I am not in USA so if I flash the rom to ZVC will I have carrier restriction? and would I be able to update it OTA to ZVD ? even if I am not in USA?
and lastly
4. Could you guys recommend a good rom which is less bloated with custom stuff and nearer to the stock international version of the phone providing the G2 experience as it should be?
Thanks.
Try cloudyfa's ROM. It will keep you with everything you need. Do not flash a d802 ROM. You will destroy your device. You can unlock it to work. Cloudyfa's ROM will allow you to use it international as you are.
...or you can just root with StumpRoot, install Titanium Backup and debloat (frost/defrost) yourself. I've always been of the opinion that the best ROM is always a stock rooted ROM. That's just my opinion/experience, no offense to any of the custom ROMs out there.
My G2 LS980 is on ZVE, i rooted with StumpRoot and froze what i considered unnecessary with Titanium Backup. Works for me just fine.
Nice to see you still around lord lugard.
Always be careful so as to not stop something that might be necessary as you can break yourself.
So very true.

[Q] Can custom rom's firmware base be different then what my phone came with?

Hi everyone, enjoying my awesome M9 like everyone else =D
and its time to move on to the custom rom goodness.
I can't seem to find an answer to the question. (maybe its too obvious? coming from s3)
Mine is a M9 (hong kong), with 1.32.708.15 (s-On) and all the custom roms are 1.32.401.17 based.
Is it safe to Flash it?
This is the only info i managed to find at the ARHD 5.0 OP with regards to the question.
"- If your current firmware version doesn't match ROM firmware version, wiping data inside AROMA is highly recommended!"
Would be nice if I can get some confirmation from you guys.
Yes it is fine right now since it is the same base. Get soff while you can so flashing firmware in the future is easy. Remember always backup first. Use twrp 2864

I did this on the M8 before, I had problems with the wifi and it took ages to boot until I found out that my firmware is old and different from the rom.
Anyway, I did what you are trying to do yesterday, (firmware 15/ rom 17) for a couple of minutes, didnt find any problems.
Before you flash any ROM, BACKUP your system and move it to your PC and use the latest TWRP
Thats good to hear! I'm gonna give it a try once i'm back in town! Thx!
Please Help me!

ONLY. use firmware for your phone. if you flash a gsm firmware on a cdma phone you are asking for trouble, big time.

Can anyone enlighten my view on this phone?

Hello, name's Mike, have been in the android side for a while and it's my first time actually owning an US version of a phone, the N900T (T-Mobile Note 3) running 5.0 stock TW. (I don't live in the US)
So please, enlighten me!
ROOT AND RECOVERY
I have tried to root it and did it successfully, however when I tried to get a custom recovery on it, I only got boot loops so far, tried various tutorials, none of them have yet worked out for me.
CUSTOM ROMS
Are there any current custom rom development for this phone? I've seen lots of KK roms but I was looking to get a stable lollipop AOSP like rom like CM12 but without crashes or battery drain. Does anyone know any good roms that are stable?
PORTING
Also! How do you port a N9005 rom to a 900T? I've seen some methods by flashing a BT+Wifi fix or something like that but it seems outdated and I don't want to brick my phone just yet.
Please, please help me out, I am really out of it. Used to Custom rom on a Huawei U8650, Galaxy S2 and on my G2, but this is harder due to it being a carrier phone.
Thanks for your comprehension.
Did you download the right TWRP? Get the tar file and odin it.

Did you check the N900T development forum? There is quite a few to select from. I.E. Slim
