[Q] [PROB] my i9500 shows up as i337 in download mode

this is driving me bunkers. so i buy an unlocked i9500 in eBay from hongkong and everywhere on the box and on the phone itself it says i9500
but in download mode it shows up as SGH-i337 and also upon using the phone (stock) it randomly asks me to sync my AT&T contacts.
the SIM card that i used is not even AT&T. and also my attempt to install CWM via odin failed.

I guess your phone is not genuine.
it might have been packed in different package.
maybe.

you mean its not samsung made? as in its a chinese fake? lol i dont think so. it just looks too normal for that

You have an i337. It's simple as that. You have probably a rom installed that's based on a i9500 rom. So nothing to worry, you just need to look in the i337 section.

i did just now, it says its a i9500

ok this is just bizzare. so installing PHONE INFO SAMSUNG i get these:
phone model: i9500
device type: jflteatt
product name: jflteuc
boot loader version: i337ucuemk2
pda version: i9500xxuemj9

once you are sure (check also what FW version you have) you can flash I9500 cwm with odin.
Odin has nothing to do with what is already installed. (expected your drivers are well installed). CWM can be pushed in.

If download mode says that you have an i337 then you have an i337.

It seems you have a true I337 because of the bootloader infos but all the rest is messed up with tricks done by former owners.
So you must reflash a stock I337 fw to refresh everything. get it from sammobile site.
edit :
ro.product.model=SAMSUNG-SGH-I337
ro.product.brand=samsung
ro.product.name=jflteuc
ro.product.device=jflteatt
These are correct infos telling that your phone is a good I337 model.

I too face the same issue...did you find any solution. Can you please share it ?

hi same problem
hi i have same poblem here and i can't use download mode to instal lolipop official or any ohter rom any solution u get there

As mentioned upthread, if the model number posted in Download Mode is SGH-I337, you have an AT&T Galaxy S4. Because of this, you will want to look in the AT&T Galaxy S4 forums for ROMs regarding your device. Unless you have no other alternative, I do not recommend installing AT&T firmware on the phone. If you do install AT&T firmware, it will work, but it will also update the bootloader to a version that disallows rooting and custom ROMs.
Ideally, you want to get your money back from whomever sold you the phone. Frankenphones are nothing but trouble.

that actually wont work. you cant flash a stock rom on these . i tried the appropriate hong kong firmware and an i337 firmware. they just fail.

^ exactly
my friend had a phone like this. bootloader was t mobile, but wouldnt install rom using odin
I flashed cm11 for GPE and and baseband modem from m919 using cwm and it finally worked
I think these phones are made using working parts from different phones

[Q] Just bought i9505 from China with i337 bootloader

Hi community I got my SGs4 from China and it is i9505 but came with i337 bootloader and Baseband,TW 4.3MK2
I got this from the phoen info app:
GENERAL INFO
Phone model:GT-i9505
Device type:jflteatt
Product Name:jflteuc
FIRMWARE INFO
Bootloader version: I337UCUEMK2
Baseban version: I337UCUEMK2
PDA version: I9505ZHUEMK2/i337UCUEMJ6
CSC version: i9500ZSUEMJ6
OS INFO
Build number: JSS15J.I9505ZHUEMK2(I337UCUEMJ6)
I want to know what firmware can I flash( because I want to update to 4.4.2 but dont know the right firmware),is my bootloader locked,can TWRP be install or do i need SS? and anything you can add will be appreciated
Well I think this info is important if you need more just ask me,if you need my build.prop I´ll upload ,looks like a hybrid firmware between I9505&i337

This seems like a definite Frankenstein. AT&T bootloader and device type, I9505 PDA and phone model, and I9500 CSC.
Your first task will be to download the AT&T firmware and install it. Then you need to borrow a friend's AT&T SIM and test to see if you're getting LTE. If you get LTE, then you have an AT&T phone, regardless of what anything else says. Unfortunately, that will mean you have to use Safestrap.
How much did you spend on the phone?

Right Now I'm on mexico with Telcel, my friends are on USA T-mobile,Verizon, Try to use Telcel LTE data and it connect to 4G, LTE logo dont appears.
I went to sammobile and download the 4.4.2 from hong kong, I'll flash trough odin to see what happens
I Got it on ebay for 255 dlls when it arrive home the phone was sealed

The fact it was sealed doesn't mean much. You're the second or third person I've seen on the forum asking about this, and in the case of the first user he was able to get his device working perfectly using the AT&T firmware. Regardless, the fact you weren't able to pick up LTE is a clue. It leads me to believe that in this case the phone may be correct but the firmware wrong. Here's why.
If you had an AT&T phone, as I suspected, your phone should have picked up LTE if it was unlocked for use on any carrier, as both Telcel and Nextel use band 4, while Movistar supposedly uses band 2, bands which an AT&T phone supports (bands 1, 2, 4, 5, 7, and 17). Check Telcel's coverage map to be certain you have LTE coverage in your area.
Neither an I9500 nor an I9505 would pick up those LTE bands. The I9500 doesn't have LTE at all, and the I9505 has LTE bands 1, 3, 5, 7, 8, and 20. Neither phone will get LTE in North America (including Mexico). The best those phones will do is HSPA+, which on the AT&T firmware would be labeled as 4G.
Try the firmware you downloaded, but I suspect you're going to want to return the phone if you want LTE service.

this phone.....

This is the scenario with my *chinese* version of the i9505.
I downloaded CPU-Z and it shows hardware: i9505, however, kernel build is a AT&T one.
I am REALLY SKEPTICAL to flash CM11 on it because I am very afraid to brick this phone. paid 300$ for it.
The funny thing is, I have the EXACT same phone as OP.
Anything I could try? please note AT&T doesn't work in Canada, nor I can borrow someone's AT&T sim card.
HOWEVER, I do have experience with a previous confirmed i337, and with bell it picked up LTE waves.
However this one doesn't.
Probably safe to flash?

I think my pat response to anyone purchasing these phones from now on will be to return them and purchase one through a Samsung-authorized retailer if Swappa isn't an option. For example, as of the time and date I write this, on Swappa there are currently 32 of the AT&T Galaxy S4 available, with prices ranging from $184 to $500US. The T-Mobile version, which doesn't have the locked bootloader of the AT&T model, has 8 devices available with prices ranging from $255-$310US. That doesn't include the Active variants or the MVNO-branded phones.
Purchasing a cell phone through eBay is, to be blunt, dangerous. You have no guarantee that the phone will be clean for activation, no guarantee that you won't have to do additional work to get the phone working, and no guarantee that the phone is even legitimate. Couple that with the buyers not doing their homework before purchasing and you get a clusterf**k of major proportions.
So, return the phone. If the seller doesn't accept returns, do a chargeback on your credit card. Or else put it up for sale as a parts phone.

Albie, can you please let me know when you get home if the phone picks up AT&T LTE waves? I am convinced this is the i9505 due to the baseband and specific board details (which correspond to the i9505 model rather than the i337, but not GPE)

I did some more snooping around desperately trying to find out more information about this phone and the last thing I remember reading about before going to bed was:
No matter what we try, this phone is with a locked bootloader after the knox 4.3 update.
Unofficial firmware can and will brick this phone resulting either in a soft-brick OR, for the more unlucky ones, even a hard brick.
BUT, I also found other contradictory posts claiming that regardless the presence of the knox update, the bootloader IS infact unlocked.
It's hard to take a side due to the lack of tools to verify if the bootloader is in fact locked.
Could you please do me a HUGE favor?
if yes:
Go to your download mode and if possibly post a snapshot of the screen. I've included mine.
For some stupid reason, even though it's a i9505, it is recognized as AT&Ts SGH-I337.
Since I don't have my camera lying around, I'll write word for word what's on my screen:
ODIN MODE
PRODUCT NAME: SGH-I337
CURRENT BINARY: Samsung Official
System Status: Official
Knox Level Lock: 0x0
Knox Warranty Void: 0x0
CSB-Config-LSB: 0x30
Write Protection Enable
eMMC Brust Mode: Enabled

If this flash works for you, please let me know.
If the BL is unlocked in the Firmware you're trying to flash to it, Please let me know.
I want to go out of this nightmare and continue with my work.
and if you could share links in a PM to me or here, that would be simply perfect.
Cheers and thanks for everything

Anxiously waiting your progress!

It's simple.
You got an SGH-I337.
You probably got a rom installed that is ported from I9505 and they didn't edit the build.prop.

I'd crack open the phone and look for the model number on the motherboard. That would eliminate any and all confusion.

MK2 & NB2 for i9505 HKong version give "secure check Fail:system" cant find answer for that......with the 4.42 firmware it gave me "secure check fail:aboot"

You have a Frankenphone, which in this case is a Sprint phone modified to look like an I9505. The proof is in Download Mode. While these repair artists can modify the software simply by editing the build.prop file, they can't change the model number in Download Mode. Therefore, whatever model number is displayed in Download Mode is the model number of your phone. In this case, Sprint.
While some of the custom ROMs here may function on your device, stock ROMs, bootloaders, and modems need to be downloaded from the Sprint S4 forums.

That's right. You cannot flash a stock I9505 ROM on your device because it's not an I9505. You've already been given directions in this thread on where to go for firmware for your device. Honestly, if it's not too late I'd go and get my money back for this device and buy one that hasn't been modified.

can u guide me for wifi and bluetooth fix also

Go to the Sprint S4 forums here on XDA and look for the fixes you need.

Help PLEASE!

Hello,
I bought a Samsung Galaxy S4 with 4G (used) and was everything working perfectly. However, to be used, restored factory settings to start used the S4. With that, my SIM card (however recognize other carriers) and did not recognize it, I tried to make the unlock / change firmware / ...
When trying to install a ROM of Brazil, Odin error, coincidentally checked on the mobile screen that had written SGH-I337, logo is a US S4, with I9500XXUGNG3 firmware (4.4.2 Russian). With that, I thought the ROM was blocking my SIN, it tried to install an original ROM that SGH-I337 model and upgrading to Android 5.0.1 Lollipop ... ROM came full of AT & T apps, and left me quite disappointed.
In short, I am with a horrible ROM and without using my SIM card (I'm thinking it's physical problem).
Can anyone help me restore / install a factory ROM, if possible, Lollipop? I'm trying to do one week and could not.
Already, thanks!
Sorry for the English, I'm using a translator.

I had already reported it, but has to take this question .
It is a SGH- I337 . So I can only install roms the i337 AT & T ? Is there any clean rom ?
I already concludes the problem of my SIN card, is that the device 4g band is different from 4g Brazil , therefore, it does not recognize . But he recognizes the other SIN Card 3g Brazil . Will I have to buy a SIN Card 3g or if there is a possibility to change the band that s4 find my SIN card would be even better.
Remembering my S4 had a rom i9500

Before flashing anything else, install the Samsung phone info app to confirm the bootloader version in the phone.
If the bootloader is 4.3 or newer, the bootloader is locked and you cannot install twrp or cwm. You can install safestrap and flash custom Roms based on stock Samsung Roms.

Nope, i337 and 9505 are slightly different as they support different frequencies and the bootloader on the 337 is locked.

The cool thing is that the i337 was this I9500XXUGNG3 firmware that had the ability to use Portuguese Brazil , I would like to return to this firmware. How I do? I tried by Odin but always of it :
<ID : 0/011 > sboot.bin
<ID : 0/011 > NAND Write Start!
<ID : 0/011 > FAIL !
do you have any idea?

The bootloader is locked so you can't install 9505 firmware on the i337.

which leaves me with great doubt is that it was with this I9500XXUGNG3 firmware stating it was a i9500 .
with this I tried to install android 5.0 thinking that manages to come unlock my SIM CARD and still not resolved . I think a matter of size or shape of the SIM card , seila . I have a lot of headache to solve this.

Do you flashed back to stock i337 firmware and it won't accept your SIM card unless you enter a network unlock code?

I am currently using with another SIM CARD and runs regular without typing unlock code and whatever be 4.4.x as 5.0.
However the rom one that I managed to install this was " http://forum.xda-developers.com/showthread.php?t=2674223 " with root.
So I would like to set up a Stock ROM that was clean , without anything of AT & T , which before I had with I9500XXUGNG3 firmware (including Portuguese Brazil )

Did you put a pin on your sim? Did you enter the sim code too many times and the phone locked the sim?

no ...
Forget History sim card hahaha xD
Can you help me one installing a rom for this i337 without the AT & T ? Preferably a clean like that had previously , as i9500 .

The bootloader is locked on the i337 so you only flash ROMs using safestrap.
If you want to remove ATT apps, you'll have to root and use root explorer to delete them. You could also try Titanium Backup to remove apps.

Need advice please help and be kind. Flashing questions

I picked up a used S4 on Tmobile the SGH-M919 on 4.4.4.
I was having terrible battery issues. I replaced the battery with no success, then the MicroUSB port failed. I replaced it and the phone would charge but it would not be detected by my computer. I tried mutiple cables and there was no change. What I wanted to do was flash to an image that was stripped of the Tmobile apps and see if that helped.
Since I couldn't do that I bought another used S4. It's an AT&T phone SGH-l337 on Android 5.0.1. The phone physically works fine but it has the AT&T branding and I would like to get the Tmobile branding on it so I can use Wifi Calling.
I've read competing threads about how it can be done and others saying how it can't be done. I need to know if the chance can be done by someone who can read and follow instructions but can't find solutions on his own and work on them.

The AT&T s4 forum is here: http://forum.xda-developers.com/galaxy-s4-att
The T-Mobile s4 forum is here: http://forum.xda-developers.com/galaxy-s4-tmobile
Put the AT&T s4 into download mode and look for the term "warranty bit". If you see that, the phone has a locked bootloader and cannot be flashed with any ROM other than a ROM that can be flashed using safestrap or flashfire and it must be based off a stock s4 AT&T ROM.

I see the following
ODIN MODE
Then in white it says what I have as green
PRODUCT NAME: SGH-I337
CURRENT BINARY:Samsung Official
System Status: Official
KNOX KERNEL LOCK 0x0
KNOX WARRANTY VOID: 0x0
CSB-CONFIG-LSB 0X30
SECURE DOWNLOAD : ENABLE
WRITE PROTECTION : Enable
eMMC BURST MODE enabled
I don't see anything that says Warranty Bit however.

I should have made reference to the word "Knox" in my post as well. Since it's present in download mode, the phone must be running a 4.3 or newer bootloader which means the bootloader is locked.
Which rom is on the att s4?

I see a build number and SE for Android Status and Baseband

What are the last 3 characters of baseband?

0C3 or OC3
It's I337UCUG03

Looks like the phone is running android 5.01 which definitely means it has a locked bootloader and you can't flash non-stock based ROMs to the phone.
I'm not sure if you can get T-Mobile wi-fi calling enabled but this may help: https://forum.xda-developers.com/galaxy-s4-att/general/convert-i337-to-m919-wifi-caling-t2896719

Thanks, I guess I will have to decide between Wifi-Calling or being able to attach the phone to my PC

The usb flex cable from the i337 will fit in the m919.

If by usb flex cable you mean something like https://smile.amazon.com/gp/product/B06Y5QTX68/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 it will fit but not function except to charge. I made the mistake of ordering this part for the T-Mobile one.

I recall using a T-Mobile s4 motherboard in an i337 with charging and data transfers.
Sure the USB cable isn't defective?
