Probably a dumb noob question but will simply flashing 900T firmware onto a 900V turn it into a 900T? Or is the hardware different or somehow permanently branded? Thx.

I have a rooted an unlocked i337m. It has an imei of 0 and I have no idea what to do since any Sim card I put in it says unregistered Sim.
1. Can anyone please point me Ina direction of a DIY fix?
2. I was going to try and flash back to stock via Odin since I'm only on 4.2.2 rooted but the phone was rooted when I bought it and bloatware removed.so I have no idea what carrier it's on. Any ideas on how to find that out do I can know which stock firmware to flash? Thanks for any help
If no custom rom or buildprop modified, you should be able to check buildprop for original carrier afaik
Hi guys i have an M919V s4 and my question is can i flash a different variants say for example 1337M modem file to mine, im trying to flash an old modem so that i can unlock my phone using the *#0011# method. I am rooted and running a custom rom so what do you guys think is it possible? Could i flash another variants modem unlock my phone then flash my carriers rom and keep the unlock?

I doubt it. It's not made for your model so chances are it won't flash or won't work. Try using RegionLock Away or finding your phone's older firmware on sammobile and extracting the modem with 7zip and ext2explore.
Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before. And is it possible to use custom Roms from At&t in other countries thanks in advance [emoji2]

The Sgh-i337 is basically the same as the gt-i9505 EXCEPT for ATT locking the bootloader on that model.
You CAN Sim unlock it so you can insert your Sim into it. You will have to reach it a bit though. It helps if you know what firmware is installed on the phone. If it is MDB, MDL, or MF3 it would be easier to do I believe. Either way look for the threads about unlocking.
If you have NEWER firmware then there are separate threads for it, and it will more than likely need to be rooted, flash a older modem, then perform the Sim unlock from the menu. If you cannot find the correct post I can help look for it later.
Just reply back with WHAT firmware and Baseband you have installed on the phone and we should be able to help you further.
If you do have MDB or MDL firmware do NOF update it...

Thanks for reply ,I have NC1 firmware and I used Method 3 on this guide http://forum.xda-developers.com/showthread.php?t=2595457 .SUCCESS!
Could you recommend a modem I could try other than MF3 as the signal isn't that great ?

Not sure which would work best for your area. You can download and try any/all of them until you find one that works best. You can switch back and forth with no issues without worries
Hi,
I had bought a Canadian s4 on ebay with version 4.4.2, I had root it for unlock the Italian language, and worked fine for two years but without ever receiving the H + and H bands, he was always on LTE or 4G...
A month ago I decided to do an upgrade it and factory reset because te phone had become very slow, so after total wipe I downloaded the stock Lollipop I337MUMUGOH3 Trinidad & Tobago (because unlocked and more native language) and flash it with Odin, but after the softkeys have not worked ... I tried some other stock rom without succes, with I337MUMUFNE2_I337MUUBFNE2_TTT 4.4.2 the touch is coming back to work even if typing * # 2663 # the phone shows fw version is 0x10 and the part's fw version is 0x1a and can't get touch fw update (IC's F/W is higher than Bin's F/W), but I lost LTE bands, now working bands are always H and H+ and never LTE or 4G ....
I tried to install different modems taken from other stock rom, but without success ...and QPST show me all bands enabled...
Maybe i must change the baseband ??? Witch baseband? And how can i do it??
How can I get back the lte without losing softkey? And how can update the softkey fw?
I do not know what else to try :crying::crying::crying:
Thanks in advance..
I recommend not trying to flash the AT&T s4 sgh-i337 firmware to the Canadian s4 sgh-i337m. If you are able to flash the stock AT&T firmware onto the Canadian s4, you will have a locked bootloader.
Did you change your cell provider? Does the sim card get LTE in another phone?
You can flash the stock Canadian LP ROM from sammobile.com to see if the buttons work properly.
I recommend not upgrading the touch firmware at all as there is a chance it will disable all touch functions.
But my model phone is SGH-I337M!!

The sgh-i337m does not have a locked bootloader. The AT&T s4 has a locked bootloader so flashing at&t firmware to your Canadian s4 could result in a locked bootloader or a bricked phone.
There are no stock ROMs for the at&t s4 above 4.1.2 from sammobile.com like there is with the Canadian version.
It's up to you If you want to flash AT&T firmware to the Canadian s4.

I'm confused, I need some advice how to restore lte bands on my phone without broke the softkey, I did not say want to flash the ATT firmware....
Some ideas?
I apologize for referencing the AT&T firmware. I misread your original post.
Have you tried flashing firmware for a Canada. It doesn't matter whether your flash firmware for Rogers, Telus, or Bell as long as it is at least version OH3.

But the Canadian firmware not work properly in Italy, I used it for 2 years without H bands, the TTT firmware is for the same phone but is open, maybe I must change the csc?
I suggested flashing the Canadian firmware to see if the firmware fixes the problem with soft keys. Once that is fixed, you can try other fixes to get lte.
You can flash the stock Canadian lollipop ROM and change the csc by dialing *#272*imei#.
I didn't know what I was doing.
I have an international S4 GT-i9500 and it had an unlocked bootloader. I wanted to try out Lollipop and installed a firmware image which turned out to be a Verizon firmware for the I545-VZW. I'm now running Lollipop, but the bootloader is now a dreaded locked Verizon loader (OF1, I believe). I've already accepted that I'm screwed, but I'm holding out hope because the phone is not an I545-VZW. The labeling and physical characteristics of the phone indicate that I have a GT-i9500, but software info tools now report that I have an I545. Has anyone else dealt with this kind of firmware mismatch and can I flash a more recent international (non-Verizon) firmware and bootloader? Perhaps the GT-i9500 does not include the same hardware features (eFuses?) which allow the I545 Verizon phones to remained permanently locked? Or are they really the same phone but with different software?
I just need someone to confirm that I'm screwed and recommend the best firmware version for my situation and point me in the direction of at least getting root and SafeStrap or whatever and a TouchWiz rom without all the vendor bloat-crap.
Thanks in advance!
Erik
