I seriously need help with this

Okay, so my Android 4.3 AT&T Galaxy S4 is rooted (through Kingo) and the only reason I did it in the first place was to flash CyanogenMod or some stock Android variant. Now I'm being told I can't install a custom recovery on my phone for two reasons. 1) AT&T locked the bootloader 2) I'm running Android 4.3.
Now, I'm considering unrooting my phone but even that's unclear and confusing, and it's hard to find people on these forums who are willing to help with these relatively simple (to the non-newbs, of course) things.
Can I flash a custom recovery? Can I run CyanogenMod or any good ROM? If no, will I be able to, ever? If no, how do I unroot? Would it be wise to just wait for the next update from Samsung or AT&T and install it so I automatically unroot?
Much appreciated.

im not confirm with it but i read theres a tool called "loki" with it you can unlock your bootloader and run custom firmware. but the rom must provisioned with loki.
search for it and read you in.
hope i could help you a little.

Root it, are you planning on installing a custom rom? If so then you won't have to worry about it auto updating but if not remove two files. Fwupgrade.apk and sdm.apk

Yes i will probably do a custom rom i havnt looked into them but im thinking it might help towards getting 4g with straight talk. Do you happen to know if they will need the phone active to do the jtag or if i can transfer my number to have a phone while its out

I doubt the phone will need to be active to perform the jtag service, I don't see why you can't transfer your number to another phone. I've done it in the past and it was quite easy

Ok thanks again im gonna send my phone out fri and found a guide to root it once i get it back. can you or anyone recommend a good custom rom with a guide to install and ive been having trouble with finding a i535vrbmf1 baseband download and how to install that also i wont need for about 2 3 weeks and will continue to look around myself

[Q] Few questions regarding upgrade/root from 4.1.2 to 4.4.2.

Hello.
I have Samsung Galaxy S3 SCH-I535 Verizon.
Android version 4.1.2 with MF1 baseband.
I have rooted my device + have TWRP more than a year ago.
However, I was away for more than year, and I am really lost on how to upgrade my stuffs to 4.4.2.
My OTA upgrade is not working, it just goes back to TWRP screen on reboot and I cannot proceed from there(maybe I don't know what to do).
Can anyone please give me detailed information on how to upgrade my s3 to 4.4.2?
+ How do I check if my bootloader is locked or unlocked?
Thank you so much in advance.

You have to do a factory reset in order to upgrade to 4.4.2, on 4.4.2 it's a locked bootloader with no custom recovery FYI

Sorry to step into your thread, but factory reset then take OTA Shapes? That's it?? That's too easy. Don't have to Odin or anything?? Thanks

I used the following thread to move from Jelly Beans to Kitkat.

And then used towelroot to root.
Then followed this thread for custom ROM.

And now your bootloader is locked down. No more custom roms other than the BL roms available. Only TW roms and that's it

Alright. Here's the thread, be advised the bootloader will be even more locked down. With TW 4.3 there is more options for roms. With the 4.4 update your stuck with 3 options

I know it can be done on my GS3 SCH-I535

Hello everyone. This is my first post and I am quite new to the world of smartphone modding. Literally, I have only been learning about this for a few hours. In those few hours I have been able to root my SCH-I535 4.4.2, soft brick it and reflash the stock ROM using odin. So I learn fairly quick and can follow basic instructions. Anyways, thats my intro.
So here is my goal:
1) Update my GS3 SCH-I535 FROM 4.4.2 TO Marshmallow 6.0.x.
So here is what I think I know:
1) The SCH-I535 has a locked bootloader which cannot be unlocked and therefore recovery programs such as TWRP or Clockwork will not work which means I cannot install any ROMS via that method. Correct? This is how I bricked my phone using TWRP.
2) There is a recovery program called Safestrap which CAN be used to install ROMS but these ROMS have to be specifically written to work with Safestrap? Correct?
So here are my questions:
1) Can anybody point me to a tutorial or help me achieve my goal?
2) Where can I find these Safestrap specific ROMS? I have read there is a version of Cyanogen13 for Safestarp. Is this correct?
Thanks in advance.

Correct, your device will never be able to use custom recovery or custom CM/AOSP based ROMs, you're stuck with Safestrap Recovery, modified stock ROMs and Xposed framework if you want to use it in addition to a ROM for more customization.
The safestrap compatible ROMs are stock based and there are no 6.0+ or 5.0+ versions for Verizon S3 that I know of unless I'm missing something.
If you want Lollipop or Marshmallow you'll have to port a stock firmware from one of the other S3 variants or other Samsung devices with similar hardware that has 5.0+ or 6.0+ stock firmware available for it.
Porting is done to convert the firmware from the device it is made for to the device you want to use it on, you'll need a copy of Verizon stock firmware and a copy of the firmware you want to port, then you extract them both and switch the vital stuff from the Verizon firmware over to the firmware you want to port. It's probably too complicated for someone with just a few hours of experience though.

Not to mention there's also no 6.0 stock roms available on any S3 variant.
Additionally OP, it's more than being compatible with safestrap, the roms have to be compatible with the stock kernel because you are unable to change that.
Only way you can get a 6.0 rom is to compile your own AOSP rom, delete the AOSP kernel, and configure that rom to run off of the Samsung kernel. It would be a difficult task, but it has been done before. Nobody has done it yet for this device. And I wouldn't have the slightest idea where to find the information to do that.

Well thanks for the replies. I guess those videos I watched are fake or maybe I just didnt understand them properly. I guess my wife will have to be happy with kitkat..
Now I just need to figure out how to root my SG5 sm-900v. Can someone point me in the right direction? I tried using a guide I found here on XDA but just ended up softbricking my phone. I reflashed the stock though.
Thanks

It depends on which stock firmware version the S5 has, typically it involves flashing a kernel then using Towelroot to root then install SuperSU then disable Knox then flash a second kernel as mentioned a few posts down in the thread linked below, it has two links you'll need to follow, a few posts below the post with the links mentions the order that you do it in.
androidforums.com/threads/verizon-rooting-samsung-galaxy-s5-sm-g900v.908621
But I think in your case your firmware might be too new and is probably locked down. It's another device that can only use Safestrap and stock based ROMs. That's pretty much what you'll get with any Verizon Samsung device these days, they're all locked from 4.3 and up, its possible to root but no true custom recovery or custom ROMs.

There is a thread linked below that is a discussion of a service provided by a company called MobileTechVideos .com to unlock bootloader for you or unbrick a locked device that has been bricked by flashing TWRP. I don't know if they still offer the service though. They may even do it for the S5, who knows.

Thanks for that post. I checked the links and it requires me to downgrage to 4.4 which I don't want to do. I am on 5.0 and I just want to root it. At this point I dont want to install custom roms or modified stock roms. I'll keep checking for a tutorial for an S5 5.0 root. I tried one here on XDA but I softbricked so I had to reflash the stock.

There isn't a working root for Verizon S5 on 5.0+ that I know of, Samsungs usually require flashing TWRP or CF Auto root but those can't be flashed on locked bootloader devices, only results in softbrick/bootloop or bricked.
