I asked the other day about using the G920I modem on my G920F as to improve the poor reception on my phone. The next question I hope anyone can answer is would just converting the whole phone to a G920I using stock rom. The hardware in each phone is exactly the same especially the modem which is a samsung shannon. The only difference is the couple of different basebands but these are present in both varients of the modem just software locked. I cant see any reason as to why I could not do this but would like to hear if you have a take on this. Thanks. I have found threads with other people that seem to have managed it but everytime I flash the stock G920I rom it fails. Just wondering what Im missing.

G920I Firmwares SUCKS, i am stuck in 5.1.1 and its a horrible experience, i miss 5.0.2 :crying:
Im on G920F 5.1.1 custom rom and its excellent. I need the modem from the G920i as it addressed the poor reception issue. No such modem has been released yet for the G920F hence I want to change. Once on G920I i will install a custom rom anyway so all will be good.

Have you tried to flash the 920I modem? I think it may be possible to do so as they have the same baseband chip.
But I am not sure whether we can get back the original modem if the flashing failed. I used to have a Nexus 4. Even when I flashed a wrong radio, I can always get back by flashing the right one. It is just a partition with constant data on the device. But I don't know whether samsung is the same.
Flashing a complete stock rom maybe impossible. I think Odin checks the model name, and prevent the flashing if they don't match (Just guess).

Yeah I tried flashing the modem only but when odit checks the PIT it fails straight away. Did try flashing the full stock package but again no joy. Its annoying as people with G920i dont seem to be suffering the issues that the G920F has with poor cell signal. Its definately a phone issue as I am on my third one lol. Have flashed the brand new modem package that was released a couple of days ago but has mad no difference at all surprise surprise. I think your correct though as odin must check the model number before flashing. Hopefully a dev could come up with a way to bypass the check as like you say the modems and hardware are identical on both models. The only difference is a couple of basebands which from my research are only software locked anyway.
You cannot flash G920I modem to a G920F and vice-versa. They are not compatible.

So I guess g920i and f have different partitions. their partition for radio may have different sizes As I found the modem.bin of these two models are In different sizes.
Can any one provide me with a Three (UK) S6 Serial number so that I can download the full official stock firmware via KEIS/Smart Switch? EDIT: I now have one from a display model PM me if you need the firmware
I need to change my unbranded (BTU) phone to The official Three firmware (H3G) (for 4G voice calling)
I bought an S6 from Amazon which came unlocked with AUT region software. I've managed to find and Flash an official BTU firmware via ODIN, however I cannot find a full OI9 H3G stock firmware.
FYI for BTU, the ones from the firmware page do not work for me (even with a PIT), I kept getting the Sw rev check fail device 3 binary 2 error. However a full official flash i.e. with the AP, BL, CP, CSC file did work. Which is why I need the serial number, or alternatively a full copy of the Firmware. I also do not wish to root/flash another recovery as I need KNOX.
Please PM me if you don't want to post on the live forum
Thanks!
I doubt someone would give their serial number, but I would suggest trying a PIT file, it may/may not trigger knox status but I did it to get EE Branded firmware for wifi calling and it worked.
Where did you get the fimware to flash to the BTU?

Already tried a PIT, didn't work... thats why I want the full firmware. I will just go and grab the serial from a display phone at a Three shop, thought XDA might be quicker tho.

As I said in your thread, I got the firmware from this thread... http://forum.xda-developers.com/galaxy-s6/general/guide-android-6-0-marshmallow-beta-how-t3277533 Its a full firmware download rather than the partials that are posted on the firmware page.
looks like @abdussamad tried it out and it solved his flashing problem as well

You have to use a custom PIT file in order for the hidden part to have enough storage so the Three firmware can work.
when i insert sim its show ctivating device and stuck on their i wait 24 hour but still on activation device when i remove sim phone works fine wifi and playing games all fine when i use custom firmware it will be ok but i want offical firmware thnx any solution plz share
are you flashing the official firmware from sammobile? are you doing so in Odin? if so, its likely a radio issue that can be solved by Odin flashing a good copy of the firmware. Ive been getting my tar.md5s from idoneapps.com for a few mos now. Theyre always solid and fast. Go grab the OK4 tarball and flash it in odin, i bet youll be good to go.
Hi there XDA,
First of all, I don't claim to be a developer nor I am here to plagiarize/steal/uncredit those developers and providers.

users running the T-MOBILE variant (SM-G935T)
There were many comments on threads as to when the firmware would update, and finally is here!
Note: I DO NOT TAKE CREDIT FOR THIS, I DID NOT CREATE THIS OR STOLE FROM ANYBODY. THE INFORMATION PROVIDED LINKS DIRECTLY TO SAMSUNG's OFFICIAL FIRMWARE WEBSITE "SAMMOBILE".
Note to the Community: This latest version is confirmed to have ISSUES with ROOT. After successful root and/or XPOSED, Wi-Fi connection, overall lag, and heating issues are present. So it is up to you if you decide to root or not.
Note to Admin/Moderators: IF YOU FEEL THIS THREAD IS NOT APPROPIATE OR IF YOU WANT TO ELIMINATE THIS THREAD, FEEL FREE TO DO IT. My intention is just to provide the community with this update for the SM-G935U (T-MOBILE) Firmware as quick as possible for those in need and for those pioneering fellas.
As soon as I am done setting up, I will surely provide you with any insight/features added to this update.
Happy developing...
RECENT UPDATES ON ROOT PERFORMANCE/STABILITY [Jan.30.2017]: This 4APL4 Variant INDEED works with the root method by @Mastajeff, I can't find any issues at all. I personally believe that this Firmware version without root works even better for whatever your needs.
*** BASED ON PERSONAL USE AND RECENT DOWNGRADE TO STOCK G935U###4API3, I ENDED UP HAVING BETTER PERFORMANCE, BATTERY LIFE, AND STABILITY WITHOUT ROOT. I JUST WENT ON TO DISABLE COUPLE SYSTEM APPS WITH EZ DISABLER. I NOTICED BETTER RESULTS, PERFORMANCE, AND STABILITY USING ROOT ON THE PREVIOUS #4API3 FIRMWARE VERSION. (THIS IS JUST MY OPINION BASED ON RECENT UPDATE I DID, BUT IT IS ALWAYS YOUR CHOICE TO WORK ON)

I am on previous U firmware API3. Is there a way to upgrade to this without losing data?
Thanks,
Hello my friend, of course you can upgrade without losing data.
But I have a quick note for you, if you have a micro sd card will make everything better.
But if you don't, just upgrade using latest Odin version v3.12 by flashing THE BL, AP, CP......AND MOST IMPORTANT THE CSC FILE....Don't flash the HOME_CSC. You won't lose anything at all my friend.

Can anyone who's flashed this confirm if the modem works with band 12, or if we still need to use the TMO apk3 modem?

As a matter of fact, T-Mobile's SM-G935T also released an APL4 Firmware update.
So we are better off flashing the latest CP File from SM-G935T into the G935U APL4 Firmware.
*will provide links to all downloads*

Hello there pal,
I've sucessfully flashed this update and the VERY FIRST THING I NOTICED is a SMOOTHER UI. During the setup I noticed an increase in speed and touch response.
Samsung Pay comes in by default and it can't be disabled by default. Other than that, the ONLY down I noticed....AND I MIGHT BE WRONG GUYS BUT....I am actually surprised to notice significant battery drain
Have you personally went on to flash this update??
APL4

I was on API3 I went to setting and clicked on system update and it updated to APL4. If you are using G935T CP modem you might to flash the API3 modem in CP to get the update. and you should not loose any data.

Perhaps quarkw something was not or was checked that caused the pit to partition your puppy with Odin. When you flash via Odin from one one rom to another there is always a chance of losing data.
Once you wipe cache in the recovery step (if you did this step) there were some other options that may have wipe the phone or your MicroSD card.
The files may actually be present and you may have lost root, if you had it. There are so many variables that could have happened.
It sucks to loose data, it does.
But look at it as a learning experience and make the time to perform the following steps next time.
If I were you, get root then get TI backup over at google play (get the paid version) to backup everything to your MicroSD that way you can always flash without losing data.
TIP: save your present contacts with their phone numbers, email address & address to Google Contacts, so whenever you flash and format, your contacts will be there automatically with you once you sign into your Google Account.
Perhaps I may write a tutorial on how to flash / backup rom & data APKs and such. It took me a while to learn the ropes too.
I'm pretty sure you flash the HOME CSC file if you DON'T want to lose all your data, thats what I've read else where here on xda

Yes if you were using the G935T CP modem you do have to flash the API3 modem in the CP section of Odin to get the OTA update for APL4. I didn't lose any data doing this.
Also I could have sworn I could still use Wifi Calling on the API3 firmware. But I definitely can't on APL4. Can anyone confirm if you do have wifi calling with the API3 firmware with the US unlocked modem or API3 firmware with the T-Mobile APK1 CP modem?

Where is wifi calling located in the settings?
Is there a battery drain?
I have a Verizon S8+ that I'm selling to a friend on AT&T. From what I've been reading it'll work on AT&T just fine but he is asking about the VVM, VoLTE, and wifi calling . I know how to use Odin from my GS5 and Note 2 days, so I assume just download the AT&T Odin firmware and prince's odin and flash everything (AP, BL, CP, CSC, userdata) will give him access to those things? Also, which CSC do I flash? If there's a better firmware/software version to use that'll let all the AT&T specific stuff work I'm open for suggestions. Any helpful links also appreciated.
Thanks in advance, I'll be back in a few hours to follow up on any replies.
