quastion about international ROM's and G 1337

Dear all
i'm not expert in AT&T stuff because i'm using the international version of the galaxy s4 , but my friend asked me to Flash the international
ROM his his G 1337 , i thought this will not possible and wouldn't try until i ask the experts here
he wants the international because its with out all the stuff that AT&t put into the phone "all software bloatware"
so what is the best scenario :
1. flashing international ROM
2. flashing custom ROM, " AT&t stuff free"
3. rooting the device and uninstall or Freeze the AT&t software "that he dose not even use any"
Thank you all

http://forum.xda-developers.com/showthread.php?t=2616221 -- has a huge list of ROMs (including international) that can be flashed on I337.

depending on his build will dictate exactly how to proceed
if mdl he doesn't need safestrap, but may need to flash his carriers kernel and the loki exploit
if higher than mdl there are different scenarios on how to proceed depending on the build. it is still all there in the link. but determine build first.
and if above mdl get familiar with hashcodes safestrap in dev section :good:

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.

I checked in dwld mode its sgh i337....can I install back stock firmware ...see this sitehttp://www.att.com/esupport/softwareUpdateArticle.jsp?sid=KB419415&cv=820

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.

i tried using odin it fails ...with some logs like receive response from bootloader fail.... :/ im getting maximum of 3/5 signals on att baseband in my country ...

Quite confused for the consideration needed before flashing any Rom and Recovery!!

I am beginner in this rooting field.. And with less knowledge I now am attracted towards flashing different rom on my phone since I am influenced by others discussion in #XDA. But when I came to meet some people in social chats, when I asked them for the, what are the requisites to be fulfilled while flashing #safe_rom without any brick.. Some says search rom on Google of your phone model i·e (gt-I9505) when I searched it there again appeared the case of #baseband version,there "google" when I got the other rom of my phone below it was written only for baseband "XXUHOJ2" and it didn't matched with mine.. In some post rom for jflte, jfltexx, sprint, .... And m confused all... And my question is.. Should all of those match to flash custom rom?? Isn't gt-I9505 all same??? Why should we consider #baseband for flashing rom or latest firmware?? Why?? Why?? Plz help me!!
-Thank you!

No baseband update
Hello and thank you for using Q/A,
you don't need to update or flash a baseband, if you want to install a custom ROM or stock ROM.
Kind regards
Trafalgar Square

And what about jfltexx,jflte, sprint.. Some post says rom for jfltexx, some says for this baseband only,, what to do in this situtation??? Is there any #compulshory to match baseband in order to flash custom rom??

Hi,
I've an I9500 who has Indonesian base, and I've flashed many ROMs designed for my device and I never had any problem. Baseband doesn't matter, however, an EFS backup should be made to be safe, so you can restore it later if you miss your IMEI after doing flash a certain ROM.
Because you've an I9505, any jfltexx ROMs should fit on your phone. You'll have no problems as long as you follow instructions provided by the developer.
I9505 doesn't stand itself. Some variants are released by certain operators in certain regions, like SPH-L720, SGH-I337, SGH-I337m, SCH-R970, etc. All variants who are on I9505 family are able to install jfltexx ROMs, but with some notes that might be available for certain devices.
Sent from my GT-I9500

You should only care about the baseband if you have a phone from Verizon or T-Mobile, as they generally have locked bootloaders.
Basebands are updated almost monthly. There is no way to have them matched.
You only need to care about your phone model.

Yes, mostly.

Got A S4 AT&T model for cheap. questions a plenty!

Since I just got A S4 I have some questions. I mainly am used to nexus/moto devices in terms of roms/etc, and I know the process is entirely different with the S4.
The model is a AT&T S4. Updated to 5.0.1
I know I won't be able to unlock the bootloader, which is okay as long as I CAN have some hopes of running another firmware on it.
All I require is Root/Xposed, and maybe CM13..or any other android 6.0 based ROM. How feasible are my options? I won't know until I physically have it, but what should I look out for in terms of firmware/bootloader codes?

You cannot run any custom ROM unless the rom is based on a Samsung kernel which means no cm or aosp ROMs.

that sucks. Guess I will sell it for a bit higher than I bought it and grab something else. Thank you.

I have an s4 (Canadian version, i337m) which doesn't have a locked bootloader and I find the phone okay with stock unrooted LP. I used to based my phone decisions on whether there was an XDA forum but my flashaholic days are behind me

G900F Rom Recommendation

Hi,
I have a G900F I got in the UK and I've just moved to Canada with. Problem is it doesn't support some of the bands here so I find I often have a poor signal. I'm happy with the stock ROM but I believe if I am to open it up for all bands I need a custom ROM.
I don't need anything too flashy, but I'd like everything to work and be responsive.
In terms of the most complete ROMs it seems LineageOS Official and Resurrection Remixed are the most popular. Can anyone comment? How about Android 6 vs 7?
Thanks

Used to use resurrection but now that I've moved to lineage os I can say that its better and getting improved every update it gets

g900f is almost identical if not the exact same as the canadian s5 g900w8.
you would need to use correct freq for your carrier, search will provide a howto. worse case scenario is to flash a canadian 6.0.1 modem from any canadian 6.0.1 stock fw

if trying to figure out connectivity, stay w/stock first as modems are from stock fw.
imo try superlite 6.0.1, it stock based and only takes a few minutes to install that way you can test out your carrier connectivity issues
https://forum.xda-developers.com/ga...-superlite-mini-mm-v1-0-361mb-g900w8-t3497158

So I can keep my stock firmware and just replace the G900F baseband (G900FXXS1CQAV) with the Bell Canada SM-G900W8 Modem and everything will be the same except the phone will work on the Bell Canada frequencies?
I had been planning to follow this guide: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 to enable the 1700MHz band which is disabled on the G900F, but if flashing a Canadian modem will enable this band that sounds easiest.
Do I need to download the full 1.5GB firmware and extract the modem from it?
Thanks

ive never tried flashing a mdm from another model as ive never needed to for the s5.
ive not read enough to know if its possible or if it has any neg consequences.
easiest would be to change freq w/current mdm, search for samsung secret service codes to view and maybe change current freq
good place to start is here https://forum.xda-developers.com/showthread.php?t=2729694

I've done a lot of research on this forum. Most people say that installing G900W8 firmware on G900F isn't possible. Also it seems that it is the NVRAM which stores what bands are allowed on what model, so simply flashing a different modem won't make a difference.
Some people are saying that the hardware is different and this is what limits the bands, but I don't believe so, the radio/modem chip is the same version between models.
Trying to follow the link I posted earlier to change the NVRAM values after installing a custom ROM appears to be the only way. Some people say it works, and others say it only appears to work. The original thread was closed years ago so I guess I'll just need to try it and see.
Alternatively I could buy 2 phones, one W8 to use in Canada and a F to use in Europe, this seems silly though.
