Hi, so my dad has a T-Mobile S3, and in 2012 i flashed it 4.1.2 AOKP rom, and now i want to update it to the latest touchwiz or something. However i seen some rom threads saying you need a 4.3 bootloader and this and that. How would i go about updating this phone? I'm not a noob at flashing or anything lol. Just dont have much experience with this device and rather not have it be a paperweight. Just need simple directions.
If you want the latest stock touchwiz, just flash the NC2 firmware via Odin. There are tons of instructions on how to do this so I don't think there's a need to rewrite them again. Everything you need is in my firmware thread and sig.

Okay! So I updated my Device (SGH-T999L) to android Jelly Bean 4.3 via OTA. Is the rooting method still the same on DocHoliday77 thread or is there some kind of complication now? And will i also be able to flash roms normally as well? Also, will it be safe for my device to Odin back to 4.1.2 ? Much question, very confuse, such complication, wow. But i do appreciate having these questions answered if possible THANKS!
Everything about 4.3 is already out there. I know its a lot but you should really read as much as you can about it.
No you can never odin flash older firmware again.
Best root option is eitther my rom (or any others) or the root66 firmware.

Okaaay! I'm going to attempt the root66 later today. Also, are there any complications with flashing roms, kernels, and all that gewd stuff??
Hi, sorry this is probably a noob question but I've been reading through the forums and got confused how to update my rooted s4. Normally I would just install the custom rom with the update but it seems like this isnt the case right now.
I'm currently on 4.2.2, rooted, and have wicked as my rom. How would I update to 4.4.4? From what I understand there is a new modem and firmware... something to do with NH7? Can someone explain to me what NH7 does. Thanks for all your help!
NH7 is the newest firmware based on 4.4.4 and it is recommended if you plan of using 4.4.4 tw roms. To update it just download the NH7 firmware from general thread and flash it with Odin, after that you can use cf-auto root to root, or if you're just planning to flash a ROM then just flash recovery and then flash ROM.. If you care about tripping your Knox counter then just know that flashing recovery or rooting will trip it

You mention that you want to update and that under normal circumstances you would simply flash the an updated custom ROM... yet you say you've read it isn't that simple, right?
You are correct, it isn't THAT simple, but it is ALMOST that simple. Being as that you are still on the old 4.2.2 pre-KNOX bootloader and all, you can flash and flash and flash all day long and a single use of Triangle Away is all you'd need to still be able to revert your device back to 100% stock, both firmware AND flash counters if you ever needed to for some reason. If you use Odin, Kies, or take an OTA update you will lose that ability. Anything you flash once you go through official channels to update will trip your KNOX counter... and that cannot be reset. The problems you've read about simply flashing an updated custom ROM is that you will have problems with data.
The data drops can be avoided by flashing the newest modem, which would be NH7. Understand though, that method only updates your GSM modem; your LTE modem would be unaffected. This would only be a problem though if you are having trouble receiving LTE where others with the same carrier can get it with no problem. If you aren't having any problems with LTE, then I would recommend to simply update your GSM modem and use the custom recovery of your choice (ClockWorkMod, Philz Touch, or TWRP) to flash any of the ROMs in the T-Mobile GS4 Android Development section.
To update your GSM modem, follow the instructions in this thread. That thread is for updating to the 4.4.2 NB4 modem, which that modem would actually be all you need; but if you wish to have the NH7 modem, just use the modem.bin ONLY file from this post instead of the modem package included in the tutorial thread. After that little bit of work, you can flash any Android version you want; from 4.2.2 all the way up to 4.4.4... AOSP, TouchWiz, or the Google Play Edition ROMs.
So from what I understand...
1. Update the modem not firmware
2. Flash ROM
So I don't need to re-root?
You are correct.
No need to re-root.
I have a Sprint L720 running a odexed stock MK2 rom from circa 2013. I followed all the steps back then flashed a custom recovery and the rom for the hotspot capability and am still extremely happy with how it turned out but... I want all those fancy new features lol. I don't really need anyone to hold my hand through the whole process but I did reformat a few times since then and have a couple questions before I start paperweightin' this.
Everything on here is MK2. Software, Baseband & Build. If i wished to flash a newer lolipop rom to my L720 would I need to apply any updates first? Can I flash the new rom from the custom recovery? I attempted to upgrade the firmware through Kies but keep running into a device not recognized error that I suspect is because I'm rooted. Anyway thanks in advance for your time!
(Mod can you please move this to the correct board, I can't find the option to delete this.)
I'm currently running CM12.1 on my phone. I love it, but I want to return to stock and give my phone an "out of the box" feel, and return it to the way Samsung made it to be.
I follow the typical instructions found here, but I always get an error (no screenshot available. Sorry!). I'm running Windows 10 and I have the proper drivers installed. Is there something I'm missing?
If the phone is running a 4.3 or newer bootloader, you cannot flash back to stock using a stock rom from sammobile.
Before flashing anything, I recommend verifying the bootloader and modem before flashing anything else. An improper bootloader and modem combination could brick the phone.

Alright. Thanks. A bit disappointed, but thanks anyway. Besides, CyanogenMod isn't bad.
I was just running CM 12.1 / 13 and I was able to revert back to Roger's Stock ROM Android 4.4.2
Try Odin3 and installing the stock rom. But you should always verify the bootloader.

If the OP is running the i747, it is the the AT&T version of the s3. AT&T never released a full firmware release for use in Odin after 4.1.1. AT&T only released OTA updates that upgraded the phones from 4.1.1 to 4.4.2. In order to flash a stock AT&T 4.4.2 ROM, it needs to be done from TWRP.

hello all, i have a fresh out of the box T999, firmware ver 4.1.2, kernel ver ends w/ MD5. i need to upgrade the firmware on this phone to 4.4.x so i can run the Amazon Flex Delivery app on it, and am kinda confused as to what the proper route is to get there from stock 4.1.2... im reading about 4.3 adding Knox, tripping 'Modified' switches, etc and really just need to know what the upgrade path is and proper order. im familiar w/ using Odin and custom recoveries, but also read that just installing a custom recovery on this phone will trigger it into modified mode in a permanent way. dont care about being rooted, i dont even think the Amazon Delivery app will run on a rooted device.
any advice or info would be greatly appreciated, thx in advance all..
The last official update to the T-Mobile Galaxy S3 was Android 4.3. If you want 4.4 or higher, then you're going to have to flash a custom ROM. If you aren't comfortable flashing ROMs, then you'll need a newer phone.
I suggest using Odin to flash the latest ROM to your phone, install the app, and see if it runs.
