[Q] Sim-unlock, root and Knox GT-I9500

Hi, i have some questions about my I9500, currently running stock Android 4.2.2 with the possibility of upgrading it to 4.3 via OTA. No Root.
1) I would like to sim unlock it, so i read lots of threads and i am really confused right now. If I try the method in this thread, http://forum.xda-developers.com/showthread.php?t=2282683 i get the following error, 'MENU NOT EXIST Current Command is 111'. I think that thats because i have an upgraded version of the modem so what should i do?
2)I am planning to root my phone but i would like to upgrade my phone to 4.3, so what about Knox and root counters and all that stuff? Every thread about this is related to the I9505 variant.
I am really a noob
Thank you!!

Anyone???

Any Luck
I have the same problem Gt-9500 region locked and UMTS Limited so apparently service model unlock method doesn't work for me, the phone is korea manufactured bought in Colombia, any luck with rooting the phone and using the region unlock apk?? Help needed desperately

Having the same problem with I9500 from Argentina. I was able to root, install TWRP, remove Knox, but not sim unlock.
Probably using a custom rom will unlock the sim. I've done this in the past with Movistar Samsung Tab2 GT-5100 and GT-3100. But for my s4 I prefer keeping default rom (for the moment).

[Q] Unlocked Metro PCs Galaxy S5 on AT&T Network

Hey guys,
Quick overview: 2 Questions: How to update to lollipop and benefits of KNOX.
I just got a new Metro PCs Galaxy S5 unlocked and am using it on the AT&T network as the title suggests. I was looking around to try and find an answer but was unsuccessful. My question is how do I update this phone since it's a Metro PCs phone (which is apparently same as T-Mobile) to lollipop and i'm on AT&T? Since I'm on the AT&T network, there is no update for lollipop yet, but from what I've read the phone itself should be compatible and ready for the T-Mobile lollipop update...AT&T is the only carrier that hasn't released lollipop update AFAIK. Here's the current information on the device:
Model: SM-G900T1
Android: 4.4.2
Baseband: G900T1UVU1ANK1
Kernel: 3.4.0-1616453
Build: KOT49H.G900T1UVU1ANK1
If I try to do the OTA Software update from the "About Device" settings screen, it says up to date. Is my only option to root it and do a custom ROM (or wait for AT&T to come out with the lollipop update...which may not be very soon)? Though if i root it I'll trigger the KNOX stuff i've been reading about. I don't think the KNOX stuff has anything useful to me from what I read, because it seems to be for business stuff only, whereas i'd only be using this phone for personal use. Which brings me to my second question: Is there any reason for me to care about keeping KNOX 0x0? Seems like it will void any software warranty if i trigger it and I'd lose any OTA updates? That's the only fall back? Because if it isn't a big issue then I can just root and custom rom my phone (recommendations on ROMs? looking for mostly performance and battery life). Lemme know if you have other questions for me or if i need to provide more info. Thanks for any help!

Im only seeing KitKat ROMs on Sammobile and Samsung Updates, for the SM-G900T1, and they generally have all ROMs available for each device
Looks like a Custom ROM might be your only way if there is no official Lollipop update for you, but Custom ROM = Custom Recovery = KNOX tripped

Yah, I was really confused by this as well. I checked Sammobile and they didn't even have the T-Mobile version which seems odd to me?

Can you send me a link to where you see those updates? I couldn't find it myself for my model (SM-G900T1).
Also, would i be able to update my phone with the latest T-Mobile Variant? I was thinking that since (from what i've been reading) it sounds like the T-Mobile phone and the Metro PCS phones are supposedly the exact same phone (T-Mobile = SM-G900T, Metro PCS = SM-G900T1) and my phone is unlocked, that perhaps I can update my phone to the latest Samsung signed T-Mobile update with lollipop and not trip Knox. Any ideas / thoughts on this?

You should be able to flash any ROM for your exact model phone
Links to sammobile are banned on XDA, just go to sammobile dot com - enter your model number into the firmware section
Need a free account to download
KNOX will not be tripped flashing stock ROMs with ODIN

thx, i was dumb and kept searching with "samsung galaxy" instead of the exact model number so couldn't find it there at first :silly:
I get that i can flash any ROM for my exact model, but was hoping to find out if i can install the SM-G900T (T-Mobile) update on the SM-G900T1 (Metro PCS)? From what I'm reading they appear to be the exact same phone, but i haven't seen any hard evidence of that fact...like i've read in other threads and other sites that people have put t-mobile roms/etc on a metro-pcs galaxy s5, and that essentially they're the exact same phone, but just nothing i've seen/read that makes it definitively so...unless that in and of itself proves their statement that they installed the TM roms on the MPCS phone. I'm cautious cause i keep reading about being careful because of all the different variants and the possibility of bricking. i guess in the meantime i'll look around more then to see if i can install the t-mobile one on my metropcs.

Ive no idea, I wouldn't want to advise flashing a ROM for a different model phone - best wait to hear if anyone else has the same phone and done the same thing
Someone here saying they are exactly the same phone

yah, i've seen that thread and it's what i meant by "i've heard things", but not really "confirmed things" hahaha
I searched a bit more and found this thread, and it looks like might be possible because someone did it on an older firmware from TM -> MPCS
http://forum.xda-developers.com/showthread.php?t=2733529
I may look a little more, but i think i'll try it and see what happens. when/if i do, i'll post back with results.

...although, would that nullify my unlock? Phone is like I said, MPCS and unlocked, running on AT&T. Switching to the T-Mobile firmware shouldn't have any affect on the unlock right?

No it won't make any changes to your SIM/carrier unlock status. Once you permanently SIM unlock your phone, that is it.

[Q] How To: Root Verizon s4 SCH-i545 version 5.0.1

I have searched and tried but i cant find any info on my specific phone . I have rooted other phones and this one seems to be the most difficult! Any help would be highly appreciated... heres my info.
VERIZON GALAXY S4
SCH-1545
5.0.1
I545VRUGOC1
KERNEL VERSION 3.4.0
BUILD # LRX22C.I545VRUGOC1
SECURITY SOFTWARE VERSION MDF V1.0 RELEASE 4 VPN V1.4 RELEASE 4
thank you

http://forum.xda-developers.com/galaxy-s4-verizon is where you want to go. This is the international S4 forum.
In short, your difficulties in rooting come from Verizon locking the bootloader.

WIsh i had found this thread yesterday since i have spent all day trying to figure out how the root this phone.... now i know why i cant.

bootloader locked
After reading your reply, I understand that there is no workaround for unlocking the bootloader. I was under the impression that this kernal SCH-I545_MD2_423399_Kernel.tar.md5 was for that. Of course it didn't work using Odin_v3.07.zip it kept failing.

The kernel and the bootloader are two different things. The bootloader is low-level firmware designed specifically to prepare the device to run the kernel. The kernel is the heart of Android. It provides the interface for the rest of Android to communicate with the hardware.
In devices not sold by AT&T or Verizon, the bootloader usually only checks to see if a kernel is present. If a kernel is present the bootloader hands off control to the kernel, which starts the operating system. In the case of AT&T and Verizon, and I am only speculating here because I have neither AT&T nor Verizon devices, the bootloader checks the kernel to ensure the kernel is not only AT&T or Verizon-approved, but the same age or newer than the bootloader, before allowing the system to boot. To prevent people from replacing this bootloader, AT&T and Verizon encrypt it so the bootloader's code cannot be manipulated to bypass the checks.
With an encrypted bootloader, rooting and custom ROMs are virtually impossible. Your attempt to install the kernel failed because the kernel was older than the bootloader. This is why, if you live in the US, you do NOT purchase a phone from AT&T or Verizon and instead, you do one of the following.
Purchase a device from T-Mobile, either outright or through installment plan. T-Mobile does not lock its bootloaders. You could also purchase a device from Sprint, but their service is the worst of the four major US carriers.
Purchase a device directly from Google (i.e. Nexus) or from device manufacturers like Motorola.
Purchase an international device and have it imported, keeping in mind that LTE may not function due to frequency differences.

Auto root i9506 locked bootloader

Hey guys, I have had limited experience with rooting. I have been looking for a way to root my i9506 without flashing it. I came across chain fires auto root. The only problem with this is that it says it can brick devices that are have a locked bootloader . I've tried to do some research on that but have yet to find a way that tells me if my i9506 is locked. Is anyone able to provide some extra info on how I check it?

It's not locked. Just go ahead and flash it.

OK thanks for the info, but how do you tell?

The only way to tell would be when you attempted to replace the bootloader, as the device would throw up a warning about tampering. However, unless you live in the United States and have a device from AT&T or Verizon, you have nothing to worry about. It's only the United States that has to worry about locked bootloaders and anti-competitive practices from the carriers who lock them.

Is there no way i could root my Galaxy note edge At&t model????

I've been waiting for a long time for someone to make it possible to root Note edge at&t model i can't find any way to root or unlock bootloader there's no custom rom for it i'd really appreciate if someone comes out with a way

if you find a way, let us know
KingoRoot can root a SM-N915A running Kitkat but nothing higher than that (and may add ads and spyware to your phone -- there is another app called KingRoot which seems nefarious, KingoRoot does not generate as much negative posts). The newest stock ROM available is 6.0.1 (have never found a compatible custom ROM).
You would think that AT&T would allow us to unlock the bootloader since they are no longer supporting the phone but apparently they just don't care, especially for those of us who have them unlocked from the network and running on other networks (mine is T-mobile).
If you find a solution, let the rest of us know. I am seriously considering swapping out the motherboard from my old cracked screen SM-N915O that is rooted with the motherboard of my SM-N915A but I am not sure if they are completely compatible and I am not sure where the lock for the bootloader resides, so not sure if that would actually help. Still, it is clear Marshmallow does not work with some updated apps so I may need to try something soon.
