Downgrade to 4.4.2 and keep straight talk - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

I bought a att n3 set up for straight talk and I want to downgrade to 4.4.2 so I can root and flash a rom.
I'm unfamiliar with the locked bootloader as I've been using sprint for a long time, when I downgrade is there any chance I'll lose the Sim unlock?
Any other issues I need to look out for?
Thanks in advance

This subforum is close to dead or people just ignore you at times. You can odin back to 4.4.2 NC2 and don't worry about sim unlock. No need to unlock it cause straight talk runs on att network, just change apn settings to straighttalk's.

[Q] Changing providers and unlocking phone

I might need to change service providers soon because Koodo is just sucking right now. As such, my phone needs to be unlocked. I would be paying Koodo for the service so that I don't have to run the risk of bricking my S5830D (can you brick your phone attempting to unlock it?). However, my little Ace is running CM9.1 RC4.1 by Wayland_ACE.
I don't know the SIM unlocking procedure and I was wondering if I would need to flash back Koodo's Stock ROM (where can I get that by the way?) and unroot it to have it unlocked.
I also heard of unlock codes around these forums and was wondering what they were, does Koodo just give me a code that I enter somewhere to SIM unlock? Please give me any information that you can on this matter.
Koodo charges $50 to unlock the SIM. Is there a safe and simpler less expensive method to unlock the SIM?
Thanks in advance.

Haha ok. I borrowed the gf's sim when i did mine. It feels good to have the freedom to use any network, especially when you own the phone. :sly:

[Q] AT&T OTA 4.3 Update with T-mobile One

I have an unlocked T-mobile One (stock) using AT&T Service. I want the new 4.3 update but I'm assuming that the OTA update is for the AT&T version of the HTC one. What would happen if I got that update? How would get the t-mobile update? Should I just root? Thanks for any help.
You'll get the update whenever your carrier wants to give it to you. If you want it now you'll need to unlock the bootloader and flash a 4.3 ROM.
So is there no way to just download the 4.3 update from tmobile on a pc and just side load it?

Of course there is. Just search for the OTA zip here. Or, if you dont mind wiping your data, you can use the RUU from htcdev,

You mean if you upgrade?
If you have an unlocked bootloader, yes, you can root and disable write protection no matter what ROM is on your X.
If you can't unlock your bootloader, then you are safe to install 4.2.2 with camera fix update, or 4.4 update. You can continue to use SlapMyMoto to root, and MotoWPNoMo to disable write protection.
BUT DO NOT install 4.4.2. If you have rooted with SlapMyMoto/MotoWpNoMo and take the 4.4.2 OTA, you might keep root, but will lose the important Write Protection Disabled that MotoWpNoMo gave you, with no way to get it back. When Write Protection is enabled (the phone's default state with locked bootloader, or the state you are in after you take the 4.4.2 OTA), any changes made to /system, or the like, (including, but not limited to, App installs, file modifications, deletions, renames, etc) are not permanent and are lost at power off/on.
SlapMyMoto doesn't work on 4.4.2, and at this time, no new working root exploit and process has been released. And part of the 4.4.2 update patches the exploit that MotoWpNoMo used, so it wont work.
The 4.4.2 update also updates the bootloader which will prevent safely being able to downgrade the ROM version on your phone. If you try to flash 4.4. or lower, you will either brick your phone, or get it in a state where you will brick when taking an update.
So then I could still take the camera update as long as I don't go to 4.4?

You can still root 4.4 as well. Its 4.4.2 that You can't, and you'd want to stay away from if you have a locked bootloader.

You should check the stickies on that. The rooting methods have been updated a lot since pre camera 4.2.2 which is what you're on. Please read the stickies and Jcase's root threads as those are going to give you the best info.
Oh ok thank you both!

[Q] Return to Fresh ouf of the Box!! aka stock!

I need to return my phone to out of the box fresh. I've been reading and searching and I'm finding info about Odin and MJ5, but I'm not sure which I need to do. The only thing I've done to my phone is root it (then unroot it) with Kingo. I unrooted it, so I could apply the stock 4.4.2 upgrade, but it fails. So now I want to return it to its original state so I can try the upgrade again. I want to keep it close to stock, because I need to use phone encryption so I can use it for work as well. I really need someone to point me in the right direction.

Thanks!! It's really involved, but I completed and it and now my phone is running 4.4. If anyone else tries it, makes sure you follow every step.
This my sound like a dumb question, but I am going to as any way. I bought a used note 3 and the previous owner had rooted it and installed saftystrap and installed a rom to the stock slot but made no back up. I searched but could not find stock 4.2.2 firmware. Any one know where I could find it. My phone is working great but would still like the option of having the stock files just incase. thanks in advance for the help.

SM-G870A with SM-G870F ROM

Hi everyone,
is it possible to put stock rom from european version of S5 Active to AT&T S5 Active? Do I have to change kernell as well, or just simply flash stock rom from G870F? Thanks

you cant flash stock G870F to your device, the bootloader is locked (research goes along way towards answering your question) the only way you would get the 870F is via a custom rom based on that device, and you cant flash any kernels no matter what.
so in short NO you cant do whatyou want,
you need to root your device, install safestrap and flash a custom rom if you want anything outside of stock.

NO YOU DID NOT UNLOCK THE BOOTLOADER, you only SIM unlocked the device for use on other carriers, you still cannot flash the stock G870F odin firmware to your device.
I'm not sure if that is 100% true. I think you can flash another but only if it is the same kernell. So if you are on 4.4.4 you can flash the same but you can't upgrade from there since the bootloader is locked. You can only upgrade an AT&T stock Rom.
Thanks for your reply. .....But i unlocked my bootloader with App called EZ-UNLOCK, is there any possibility that I still have locked bootloader....my android is 4.4.2.....Both G870A and G870F are similar in every Headwear. ....... do i need to flash kernel first......
Thanks

THANKS FOR YOUR REPLY, EZ-UNLOCK app for locking/unlocking the bootloader and it said I did it successfully,
(1). My device is rooted.
(2). 4.4.2 Stock.
(3). No AT&T firmware Support
(4). Bootloader is unlocked. (if EZ-UNLOCK did it)
So what I need to do to flash G870F stock Firmware and Kernell or official 5.1 lollipop to my S5 ACTIVE G870A At&t, plz tell me Which KERNELL do i need and where can i download it.

If you truly have a SM-G870A then I highly doubt the app worked or we would all be using it. You can flash with Odin to any G870 with 4.4.2 or upgrade to 4.4.4 and flash that equivalent. But I wouldn't mess with it if you don't know what you are doing. 5 will be out soon. AT&T is just taking it's time and we are being very impatient.
I did a quick search of that app youve used there and it says IN THE TITLE its for the verizon S3, not only that the thread for this app says its not only not been updated since 2012 but will hardbrick your device if you use it on the later firmwares. That app is most likely lying about the bootloader being unlocked. At the end of the day it is locked and we just have to deal with it and work around it.

I assume you mean flashfire, as mobile odin does not work on our device. If you didnt, look in to flashfire, it will do what you need.
