Galaxy note 3 t mobile n900t

Hi, I bought an unlocked the mobile note 3, rooted with the 4.4.2 and I want to get lollipop. So I downloaded the latest release for n900t from sammobile to install with Odin but I have a question. If I upgrade in this way I'll lost the free sim unlocked? Sorry if is it a stupid question

When unlocking a phone, there are usually two separate things this can mean; either an unlocked bootloader or an unlocked SIM. Both are unlocked (via software/code) on a hardware level, if I'm not mistaken, as I've heard of folks unlocking their SIMs and flashing all sorts of ROMs with no issues. If it's all the same, unless you're flashing to a firmware that's not downgrade-able, you can also make a full backup, in case it turns out that the flash *does* re-lock it; That way, you can always revert back to your backup.

S5 G900F/900V Help needed VERY HARD CASE

When I purchased this phone, I initially thought it was a G900F, because of the IMEI and sticker on the back, but my phone differs so, so one day while rooting I magically soft bricked it, in panic I install a VZW stock rom and BAM its normal, but before I installed VZW I think it was an international 5.0 rom, so is there a way I can go international S5, as I'm selling it and it is a better option to make it INT version,
I'm on PG2 Bootloader and stuff, please help me make it INT version, it says G900F and the IMEI matches with it

I have devised a plan, I will use Flashfire to install the G900F Rom, I'm currently running PD1 bootloader with 6.0 PF4 rom, any opinions will this workout?

Flash G900I Stock Rom to G900T S5

My mum went to the US and Mexico from Australia last year for my brother's wedding and a holiday. She bought an unlocked T-Mobile Galaxy S5 and prepaid T-Mobile SIM to use over there.
However now she's back in Australia there are a few issues with the phone such as the T-Mobile bloatware and US defaults on the phone.
I thought it might be possible to flash an Australian variant of the stock firmware from the SM-G900I and searched for instructions and thought I'd figured out how to do it with Odin only to get a Secure Check Fail: aboot error message.
Some research I've done suggests the problem is with the baseband of the firmware I found:
G900IDVU1CQB1_G900IXSA1CQB1_G900IDVU1CQB1_HOME.tar.md5
Apparently the baseband of my mum's phone is: G900TUVU1GQC2
I was hoping to flash an alternative stock rom without rooting the phone and tripping Knox since it's still within warranty.
Any help/tips much appreciated.

First of all you should never flash different software on to phones they don't belong to it would more likely brick it bt if your phone is TMobile you can easily not root it by going into the developer setting and hitting oem unlock so that unlocks the bootloaders​ from there you can you can use odin to flash TWRP (a custom recovery) and then easily root it and then flash debloat scripts made from devs on this website to get rid of bloatware

new kernel and new security patch:

I am tired of dealing with SGH-I467's (AT&T only) locked bootloader. It makes installing custom ROM impossible. Now I'm thinking of buying and swapping in a mainboard from SGH-I467M (the Canadian version is bootloader UNLOCKED) or GT-N5120 (international version).
1. will this give me an unlocked bootloader without any other hardware change? I know I probably have to swap in a new modem code, but with an unlocked bootloader, any software change is possible
2. will the mainboard from GT-N5120 work in a SGH-I467? I know SGH-I467M's mainboard will for sure work in SGH-I467 because the only difference is the latter has a locked bootloader. Unfortunately, SGH-I467M's mainboard is hard to come by, but GT-N5120's is still available. Although the LTE bands in N5120 are overseas and SGH-I467 has AT&T bands, are they really different hardware, or same hardware with different software?
[Updated Feb 9th, 2018] Now I don't think it is doable at all to download SGH-I467 or SGH-I467M's modem code to a GT-N5120 hardware even if the bootloader is unlocked. I have a Canadian Galaxy S4, SGH-I337M (bootloader unlocked, unlike the AT&T version). Since my carrier is U.S. T-Mobile, I tried to download T-Mobile's modem to my S4 thinking it may give me better data rate. Odin prompted Fail! (Auth) and S4 showed Secure Check Fail! After some googling, I realize regardless of unlocked bootloader, these phones/tablets are engineered to check if authorized modem codes are being flashed. I know for sure my S4's bootloader is unlocked because I have installed TWRP for recovery.
Since GT-N5120 has international frequency bands, turning it into a North American tablet is DOA if another carrier's modem code cannot be installed. If anyone questions why a custom ROM can be flashed to a phone/tablet with unlocked bootloader, it is because a custom ROM seldom comes with the modem code!

That firmware is almost year old now..
I have no issues with my at&t i467, it runs and does everything my modded Note 8.0 does. Except a lack of custom recovery, and kernel. All you need is to learn a bit on simple file managment and permissions, while plugging away with dropping in system files and libs. I guess I will be the only one here with a modded out yank i467 that works on EU wifi channels.
I had a few threads on libs and apps, along with settings config files to customise on your own. But everybody acts like it's complex trig. Heck i hardly knew much about android when I bought my tablets, and in a years time peeps think i am a god. WTFF!

Great idea! Thank you. Says who one has to do all mods during the Odin time and get rejected by this locked bootloader? I will definitely look up your threads on how to swap out these files post boot.

I tried to look up these posts, but you have a lot of them! If you don't mind, can you suggest the key words needed to filter them out? Thank you

Firmware from SM-T377P on AT&T SM-T377A Tab E?

I was just curious if it was at all possible to flash the firmware from the T377P model to the AT&T model (T377A) because it seems like most of the development is for the T377P. Has anyone achieved this yet or attempted flashing any other model's firmware to the T377A?

Flashing SM-T377P firmware on a SM-T377A wouldnt work, because the T377P uses a Snapdragon 410, not an Exynos 3475 like the T377A uses. Flashing SM-T377T (T-Mobile) firmware might work, since it uses the same Exynos CPU as the T377A

I'm just curious what the best alternative firmware would be to flash (if possible at all) on this tablet because there's absolutely zero development on the AT&T variant (T377A) of the Tab E. Preferably a firmware that's been successfully rooted, etc.

Unfortunately nothing can be developed for the T377A because the bootloader on that variant is locked, so that means we can't do anything to the device, even with Odin. If there was a way to convert a T377A to a T377T, or if there is engineering firmware for the T377A, then maybe development is possible.
On another note, I found somebody's backup of the Nougat firmware for the T377A: https://mega.nz/#!eHJSUCoZ!54BXNlvrL6RJfEHzS4qNOj3eqwCpxSrzrI2l_IqHe84
Contains the AP, BL, CP and CSC files.

Can you please describe what you did to unlock it? I've tried 1000 things and nothing seems to work

You have to request the unlock code from AT&T, there's a slight difference between doing it for phones from your own plan or someone else's phone (you received as a gift or purchased second hand). They walk you through the process for each type of equipment so it's relatively smooth.. I just want to remove the bloatware and have a security update more recent than tree years old. This is my main gripe with AT&T, stuck with questionable bloatware and a vulnerable version of Android (and it's locked down so tight no one can fix it on their own).

So you were able to unlock the bootloader by following an AT&T tech over the phone?

More details would be nice. A lot of us have been desperate to do something with this tablet.

it be nice i i could just downgrade from 7.1.1 to 6.0.1 or maybe 5.1.1. but i havent been able to even when using combination file via odin
