I have Samsung Galaxy s4
Model is i9500
But when I go to download mode, I see modem number to sch-i545, which is from Verizon. I want to root my phone and also want to download stock rom or flash custom rom but I don't know which rom to download because I'm confused of which model is correct. My phone has 4G LTE and CDMA. I know i9500 does not support 4G LTE but the model number is i9500 and baseband I9500UBUHOE1. Hope someone cam help me out. Thank you
The correct model # can be found in download mode; therefore, your phone is a Verizon phone with a locked bootloader.

How can I unlock?
Can't be unlocked as far as I know.
Here's a thread about unlocking: http://forum.xda-developers.com/showthread.php?t=2500826
I want to root and install custom rom, you have thread for that?
You may be able to root but no custom Roms based on cm or aosp.
More information about your device is at http://forum.xda-developers.com/galaxy-s4-verizon . In short, unless your device has an early bootloader that would allow modification, there is no way to unlock the bootloader, no way to install a custom ROM, and no way to even root the device.
Return this device and get something else.
could this phone have a locked bootloader AND still have other firmware trying to disguise it at the same time ?
No. It's likely his bootloader is unlocked, but he needs to head to the Verizon S4 forums to be sure. But when it comes to frankenphones, my instant response is to return the phone if possible. Frankenphones are a PITA to deal with.

But my baseband and bootloader version are i337 anf rest of all are i9505xxugne8 :/ and on back side of phone its i9505 printed
It's a Frankenstein. An AT&T I337 with the IMEI of an I9505. Someone changed the IMEI before selling it, likely because the original IMEI was blacklisted.
its basically a korean convert your phone might be i337 but the best way is to go to download mode and check it there. model number on download mode is always real.

If it's an AT&T device then you can install an AT&T ROM on it. However, doing so nets you a locked bootloader for your trouble. Install a custom ROM if you can, and don't look back.

of course you can install official sgh i337 firmware. just find official firmware from sam mobile or samsung updates and download them to your phone via odin. it will fresh start your phone on atnt official firmware but i suggest you to do some research over it before attempting any thing. in your case i see that your phone came with pre rooted firmware to change build.prop to make it look like 9505. i am in pakistan and this is very common here i was fooled for 9500 but it was sph l720 sprint model. best of luck with your update

you mean that I should keep using custom roms and no matter whether baseband is of i337 ....If I want to download a 5.0.1 then I will download any rom and flash through odin using pda file just....it will not chnge my baseband..
Finally I got it....its i337...I checked imei on imei.info it says it is i337 and also checked for blacklist its all clean....and I opened back cover and see it and its written "MADE BY SAMAUNG" ...spelling of samsung is wrong ...it means sticker and software are of 9505 and hardware are i337 at & t usa carrier....I think its changed in korea...phone is converted....now planning to download stock firmware of i337 lollipop and install through odin....
if anyone have link to i337 lolipop plz share
If you install a stock ROM via Odin, the bootloader will be changed, but as long as it's not an AT&T or Verizon ROM you won't suffer any ill effects. If you install an AT&T ROM there's no going back. Unlike every other country on the planet, here in the US AT&T and Verizon encrypt the device's bootloader, because they don't want you rooting the device and bypassing their bloatware and their restrictions. So, since you happen to be in a position where you have an AT&T S4 that doesn't have a locked bootloader, you want to install a custom ROM.
If you have ignored my advice and installed a stock AT&T ROM, you'll need to head over to http://forum.xda-developers.com/galaxy-s4-att and use the information there to root. Honestly, now that you know your S4 is an AT&T model, you should head over there anyway.

..i installed stock 4.4.4 ATT software but i want to install back i9505 software becoz att is not running well in my country...it lags in sending msgs and making calls and also hotspot nd other probs....can u guide me to get back 9505 software
I tried warning you but you plowed ahead anyway. The stock ROM you put on the phone is basically untouchable, because of the locked bootloader, so you now have two options: use the phone as is, or use the information in the AT&T S4 forums to install SafeStrap recovery and from there flash a custom ROM.

Hmm yeah but i think it will work fine ...only problem is of signal network....can you guide me how to flash 9505 modem on i337 ?
No, because it won't work. I tried flashing an AT&T modem to my I9505 when trying to add LTE frequencies to my device. The phone rejected the modem, but it didn't harm my I9505 either.

It could be because I didn't use Odin when trying to flash in that instance. Under ordinary circumstances you shouldn't be able to flash I9505 firmware on an I337. Regardless, you can try to flash the I9505 modem using Odin, but the results at best will be unpredictable. It certainly won't change the LTE bands on the phone as those can apparently only be changed with tools we don't have.

Hello all. I just got a new Galaxy S4 (i337m) and I hate the stock firmware on it. I want to install something custom, however the custom roms require a certain bootloader that I do not have. I have searched for if / how I can change my bootloader but none of the forum posts I have found seem to be related to my specific phone so I'm posting this to find out about my specific phone. I believe it is a locked Fido phone. I used the ADB shell to check the bootloader version and it is not the UCUAMDB or UCUAMDL bootloader I need to have for the roms Im interested in. Mine was something like CUVL. I can verify later when I get home. However, can I change my bootloader? If so, are there any instructions for this specific phone? My goal for this phone is a light weight / vanilla version of 5.1.1 Lollipop, rooted. Thanks.
If it's an actual i337m the bootloader is already unlocked... I'm a bit rusty though. I've moved on to a G4, and dumped most of my S4 knowledge with it.

How can I tell if it is unlocked? If it is unlocked, does that mean I can install a different bootloader?

@werty733: You have a frankenphone. In this case, a US Sprint phone that has had its IMEI replaced with one from an I9505. The only stock ROMs you can use are ones available from Sprint. The good news however is that your bootloader is NOT locked. That means you can install a custom ROM without too much difficulty.
Nevertheless, I would recommend returning this device and getting a different one. Frankenphones are more trouble than they are worth.

Ah, my bad.
Sent from my GT-I9500
No worries. As you likely have guessed, frankenphones are a rather common occurrence. Hopefully the OP heeds my advice and returns the phone. He's unlikely to ever get high speed data with the device, due to it looking for North American frequencies not used elsewhere in the world.

Thank you for your valuable reply,
So that means my phone has Sprint hardware, if I want to root the this phone do I have to use cf root file of SPH-l720T not the I9505?
Even the custom ROM i have to use SPH-l720T ones right not the I9505.
I actually want to root and install a custom ROM to my phone
I wouldn't even bother. Return this phone, because you're unlikely to ever get LTE service with it. Sprint doubly so, as they primarily use their own high speed network instead of LTE.
In general, I don't support these phones. However, if you choose to press on, you will need CF-Autoroot for Sprint, TWRP for Sprint, and a custom ROM for Sprint. All of which can be found at http://forum.xda-developers.com/galaxy-s4-sprint .

Hi, in an attempt to unlock Wifi Tethering capability on my phone, I installed [G900F]CyanogenMod 14.0-20161020-UNOFFICIAL-klte, and now I'm unable to make phone calls or use SMS/MMS.
Is there anything I can try to get service back?
I've tried installing a new modem with no success, using Odin, FlashFire, Terminal Server. I'm not confident I was doing it correctly though, or even if I was using the correct modem files.
I was able to root the phone with Stock firmware, but Mobile Hotspot/Wifi Tether wasn't built-in, and I had no success with any of the apps... FoxFi, Wifi Tether Router, Barnacle Wifi.
Some more information on the phone:
It's the StraightTalk variant made for TotalWireless MVNO. The phone's Stock firmware said it was the S902L Samsung S5 variant, but under the battery FCC ID of the device is actually just a G900V. I took it to the Verizon MVNO PagePlus and they were able to activate the phone, and everything was working perfect, until installing CM14.0.
A roadblock I found out, that might be the root of some of the problems, is the phone may not have the ability to unlock the bootloader, possibly limiting some modding methods. When looking at /sys/block/mmcblk0/device/cid, it starts with 11, designating a Toshiba eMMC chip.
I'll take any suggestions, or alternatives... I don't mind using the stock firmware or any other Roms. The main feature I'd like to have is the ability to use Wifi Tether and the basics, make calls, send sms.
Thank you.
I know this is off topic, but how in the world did you get CM14 running on G900V-CID11?

I'm not entirely sure, but someone had an idea they mentioned to me, that it might've been possible to get CM installed from a very outdated Android version, from before CID 11 was locked. The previous stock Android version the phone came installed with was 4.4.2. It was the StraightTalk variant made for TotalWireless MVNO. The phone's Stock firmware said it was the S902L Samsung S5 variant, but under the battery FCC ID of the device is actually just a G900V.
You will not be able to run any version of Cyanogen on your Toshiba S5 properly. Your best course would be to install FlashFire from the play store and use it to install a TouchWiz ROM such as Moar (5.0) or Phoenix (6.0).

no, no, no. don't listen to any of these other people. if your phone boots CM14 then your bootloader is unlocked. this has nothing to do with bootloaders. you installed the wrong ROM for your phone. CM14-kltevzw is the correct variant for your phone, not CM14-klte.

generally correct. best way to know would be to take a cid 11 based device, and flash twrp same way you would cid 15.
as far as i know though, most straight talk phones i see at work that i've repaired software wise have had unlocked bootloaders... which makes recovering/backing up files a breeze lol

I think that is correct. Here's the final solution I came up with and everything's working perfectly now.
I flashed the kltevzw 14 version with TWRP and had no luck getting service, then I tried flashing the kitkat factory ROM with ODIN to see if that would fix it, but ODIN failed after many attempts. Finally I flashed with the lower but stable release kltevzw CM13, instead of the nightly, and everything worked again. I'm thinking I must be extremely lucky to have gotten a Straight Talk S5 variant with an unlocked bootloader, but it's interesting that even though my CID definitely starts with 11, the bootloader is unlocked. Not all hope is lost on CID 11 S5's.

Are you able to dump your boot and bootloader partitions somehow? The "dd" command from adb shell somehow?
Couldnt we just use a diff program to compare yours with one of the Locked 11's?

No, all hope IS lost on CID 11's. You have a different phone provided by a different company. It is loaded with a different software and hardware configuration. There is no bootloader signature verification. Yes, the configuration is very similar to that of a G900V, but the bootloader comes unlocked. This is phone specific. This has no value for an actual G900V.

well if that's correct, then why does the dev edition bootloader work on the non-dev edition? Sure, its still a g900v, but never hurts to find a way and try

I say this because I have tried it and I know how it works. A bootloader needs to have the right signature that is recognized by the hardware. The reason the dev edition bootloader works on non dev edition is because they are the same phone, but with different bootloaders installed. The signature of the straight talk bootloader will not be recognized by the G900V hardware. Again, I have confirmed this personally. The straight talk is almost the same hardware as the verizon G900V, but it does not have bootloader signature verification enabled (and the bootloader that comes installed is unsecured).

because you don't have a clue about how the CID exploit works
the reason you can flash the dev aboot on a CID15 is because you can change the CID to match that of a dev edtion aboot checks the CID to see if a device as a dev edtion or not
the CID is a sort of serial number for the flash-chip and normally its write once and then read only value ,but because samsung was sloppy we can use some custom Samsung NAND vendor commands to change it so secure-boot thinks you have a dev editon and permits the flashing of a unsigned image
this is flat not possible on CID11 devices(toshiba NAND) there is no hope for cid11 devices with this method the commands needed simply do not exist PERIOD

I understand plenty enough to know the difference in the flash chips cid's with such like that... The fact of the matter i was trying to get at is that most Straight Talk phones are unlocked entirely without a care in the world, regardless of their CID/branding. Without the proper commands and 3rd party support, I get that there won't be a way. That's why I check my CID's first before buying S5's or Note 4's
Hello guys, I'm posting this for first time.
My girlfriend is having a Samsung S5 from AT&T and I want to root it as she told me system apps from AT&T are taking too much space on her phone and so I was thinking can I flash any custom rom on it?
As I see the AT&T thread separate, I want to ask some things
Does Network provider has to do something with it ?
I can flash custom rom on her phone or not?
And same odin thing works ? Like unlocking bootloader and fishing custom recovery
I have never rooted any Samsung phone ever
I'm having a oneplus and HTC.
If anyone can tell me what all do I need to do, I would appreciate it a lot .
Att version has locked bootloader .... Root is possible and there a few roms but they are all based off the stock rom just tweaked a bit ...

You should consider two things:
1. ATT phone may be sim-locked (locked to their network), but it has nothing to do with custom firmware. This problem may be solved more or less easily.
2. ATT phone (SM-G900A) does have a locked bootloader. This is a real problem.
That's why you're limited to touchwiz-based ROMs and stock kernels.
This means, in it's turn, that you cannot have root on 6.0 and above, you cannot have custom recovery, LOS, etc.
If it was my device and I was going to use it as a smartphone (to communicate with others) on a GSM network, I'd install this ROM in unrooted variant and the latest firmware (boot, modem, kernel).

It's been over 2 years for her phone, unlocking bootloader won't be an issue ( we can unlock it right?) . And she will be using AT&T only because she is using family plan.
If you dare saying the real problem is locked bootloader then we can just unlock it , or I understood it wrong
