Weird Problem with I9505

Hello all, I need some help in regards to my Samsung GS4 I9505. Sorry for the long post!
I bought this phone off eBay about a month ago and only did a quick test to make sure it was working. It is a used phone but in excellent condition to replace my old 9505.
Now 2 days ago I had some free time and wanted to check the phone more thoroughly before I transfer my data from my iPhone to the new to me 9505.
The phone had the stock ROM from Hong Kong (TGY). I9505ZHUFNL1 I think if I’m not mistaken.
I realized a few weird things in this phone.
1. First it had the AT&T ringtones installed, and 2 AT&T bloatware apps installed. I thought maybe the seller put them their thinking that I had AT&T.
2. Second, in the ABOUT PHONE, Model # shows as I9505 but the build number shows as I337UCUFNB1
Now I wanted to install a new stock ROM and root, process has failed in ODIN. (PS) I have flashed and customized my old 9505 a lot and have some idea on what I'm doing. I am still a newb though!
Currently I can get into Recovery and Download Mode but my S4 does not boot up. It gets stuck on the logo “SAMSUNG GALAXY S4” As you can see from the pictures below it shows PRODUCT NAME as I337 in DOWNLOAD MODE and shows kot49h.i337ucufnb1 in Recovery.
I am trying to flash stock ROM but ODIN has failed. Tried TGY, DBT and even AT&T ROMs and nothing is working. Tried to use KIES and nothing, went into recovery and deleted everything. Still the phone is not working.
I also got this AT&T message about “System software not authorized by AT&T” but that message is gone now after I flashed AT&T I337 Stock Recovery.
I have searched all over the net and these forums to try to get the phone back up, so far nothing is working on my phone.
Attached are pictures showing model #s and an error I got while trying to flash stock ROM.
Any ideas or suggestions on what to do next? Thanks in advance

I think is a refurbished device. But try to download, unrar and flash this firmware via ODIN: HERE. This is the STOCK firmware for your i337 (in theory). Tell me how it went and good luck .

Thank you. Downloading it right now. Which Android version is this?

It's android 4.4.2. We gona confirm that you have a refurbished device or no. Tell me too what errors appears in ODIN in case you have them. Dial *#1234# when the process of installation finish and tell me if all go ok.

Thank you soo much!
Some good news. I flashed the file and now device is up and running with the AT&T ROM. No errors.

CSC: I337ATTFNB1
Even phone model shows as I337

Be relaxed then. You own a SGH-i337, no a GT-i9505. The previous owner was flashing wrong firmware for sure. Enjoy your "machine" and Merry Xmas. :highfive:

Thanks mans for your help and Merry Christmas. Well I am not relaxed since I need a I9505 not AT&T. I'll be moving to the Middle East soon and so the AT&T will work there but I cannot use 4G LTE.
So he most likely even replaced the sticker under the battery to show I9505. I checked the IMEI under the cover and using *#06# and it matched. I checked IMEI online and it shows the model as I9505.
What the heck did the seller do to this phone? Salvaged some parts from AT&T model and installed it?
Just to do a small experiment, I'll get my friend's AT&T SIM card which have LTE and tested it on this phone to see if I get LTE or not.

1. I was telling you before is a refurbished device. They mix parts of differents models for create one new monster, like Frankestein .
2. I checked the original SGH-i337 and it has LTE. Take a look for yourself: HERE

I'm such an idiot! I missed the part about you saying it is a refurbished model. Well this is first for me knowing that they can build Frankenstein S4s! This particular phone is quite misleading.
Also yes you are right SGH-I337 has LTE but will not work in Middle East since we use different LTE frequencies there.
I'll get back to you after I do this small test just so I can feel a little better!

Joku1981,
I just used my friend's ATT SIM card and it connected to ATT's LTE network. Pic attached.
Thanks for your help. I'll contact the eBay seller and see what he can do. Worst case scenario I'll try to sell it on eBay.
and Merry Christmas!

How much did you purchase it for off eBay?

Bought it for $250. came with 9505 box, original charger, usb cable(looks non-oem), manual and headphones. It is also unlocked. Tried a SIM from T-Mobile and it worked.

[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 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'm not a AT&T user my apologies, I used to be Cleartalk wireless user(took my verizon SGS4-i545 and flashed with them) but I drop the contract sell my phone to buy this SGS4-i9505, I'll be hard to get a AT&T sim, I download from Sammobile the i9505 4.4.2-NK2 firmware from hongkong and then try to flash through Odin,because 4.3 has a poor battery life in my case,but before I flash it I'm making a Flashable Zip for safestrap to extrac the "build.prop" and see what is in there, because may be this update fix some problems :fingers-crossed:

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

We have the same download mode screen -_- u.u ,I try to flash the NK2 and it fail than t means we have a locked bootloader :'( ,couple of minutes ago I dowload the mk2 & NB2 for i9505 from Hongkong I would flash them at 10 pm pacific time I will keep you updated my last resource will be to flash mk2 for the AT&T variant in my case I can live with that if root is available ooo! just found a threat to get 4.4.2 NB1 but it is for the i337 anyway Let me see what happens with the 2 Downloaded firmwares

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"

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.

But previously i am running baseband of 9505 on i337

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.

After that some of the apps stay in english and others change their language into chinese( i'm not sure if its chinese but it looks like it). phone runs on android 4.4.2. i tried to uptade it to android 5.0.1 with odin but everytime i try it fails either in re-partition or nand write start. Enyone can help? I tried using differnt cables, usb ports and even diferent computers, always switch off antivirus and kill kies, and start odin as administrator.

Enter download mode and tell us the model number displayed there. That way we can rule out a Frankenstein phone and help you better.

it's not a S4 I9500 , it's a SHV-E330S with diffrent hardware processor 2.3GHz LTE advanced , dont try to upgrade with I9500 Firmware you gonne brick your phone , take look here and try one of this firmwares http://www.sammobile.com/firmwares/database/SHV-E330S/

I didnt know that. I only checked in settings and model number displayed there is gt-i9500 but im pretty new to samsungs so i'll try with that. Thankfully nothing bad happened.
One more question, can i use only firmware for shv-e330s witch is for south korea or can i also use firmware for gt-i9506 witch has csc dedicated for my country. As i checked it shv-e330s and gt-i9506 are the same.

You can only use firmware for the E330S. Odin will reject attempts to install the I9506 firmware on the device. If there are custom ROMs available for your device, I would use one of them.

Thank you, dear sir. I'll certainly do this.

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.

a question, i337 = i9505 ?

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.

and 9500?

9500 does not use a Qualcomm processor.

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.
