I have recently updated to a 4.4.2 firmware from BTU region with baseband I9195XXUCOD3. I now want to install a firmware from ROM region but the latest baseband available with firmwares for this region is I9195XXUCNK1.
So when I flash the ROM firmware, the baseband does not get downgraded and this breaks the Wi-Fi. I guess the slightly older firmware cannot use the latest baseband version.
So is there any way to downgrade the baseband?
Thanks
Turns out that the good old method of flashing the Brazilian (ZTO region) 4.2.2 firmware I9195UBUBNE2 works even to downgrade this baseband!
So I successfully downgraded to 4.2.2 and then flashed the ROM region firmware which now works like a charm.

Hello guys. I am currently running android 5.0 (V20A). Can I downgrade back to android 4.4.2 and if yes can I do it by just installing a 4.4.2 firmware ?
Yes.
Just flash stock firmware for your variant.
My baseband version is currently I747MVLUFNK2 is this the lastest modem? If not, where could I get just the modem or do I need to flash the stock rom to update the modem?

The latest I have seen mentioned is OB1. I have not seen any files posted here for the modem or modem/bootloader combination. Unless you can find such a flashable you will probably need to flash the stock rom. I have seen the OB1 rom available for the i747M posted to sammobile.
Samsung noob here.
Bought a used Galaxy S Tab 10.5 a month ago. For some reason it's still on KitKat 4.4.2 and never got the update to Lollipop.
Any idea why?
Model: SM-T805W
Build #: KOT49H.T805WVLU0ANF5 (I search all around but couldn't find any info on T805WXXU0ANF5)
Carrier: Bell Canada (Although I don't use mobile data and only have an expired T-Mobile SIM in it to get rid of the "No SIM" message. I only use WiFi.)
Probably because there is no marshmallow rom at the moment.
Latest is 5.0.2 and can be downloaded from SamMobile.

Oh snap I meant Lollipop. Fixed OP
According to sammobile.com this is the latest firmware for T805W model:
Date: 2015-09-01
Version: Android 5.0.2
PDA: T805WVLU1BOD7
CSC: T805WOYA1BOD7
Are you non-rooted stock? As far as I know, one reason when OTA updates are not offered is when ROM status is not official or if the system is rooted (maybe when it is stock rooted, OTA is offered but cannot be installed).
Anyway, you can download the original firmware from sammobile.com as ashyx suggested and flash it using Odin. There are plenty of manuals how to do that here on xda.

Good Evening, Everyone,
I just bought a used SGH-i747M 4.4.2 i747MVLUFOB3 3.4.0-1784548 [email protected]" BUILD KOT49H.I747MVLUFOB
Seller said It was on Koodo.
Might I ask you a few questions ?
1) Are there advantages to flash Rogers radio as I'm on Rogers ?
2) What is the newest Rom (Lollipop ? Marshmallow ?) that you have been using Without-Losing the Stock driver to enable the use of a MHL Cable (I have one) ? MHL means: USB->HDMI .
3) Any steps you feel I should know before ? Ok, immediately flash TWRP, then Full backup with TWRP.
Any signed TWRP flashable with stock recovery ?
4) Flashing this will Unlock the Provider ? Rogers' modem: https://forum.xda-developers.com/galaxy-s3-att/general/modem-4-4-2-modems-i747-i747m-t2856577
Thank you All.
Flash the latest stock ROM from Sam mobile which can be found here: https://www.sammobile.com/firmwares/database/SGH-I747M/RWC/
Rogers, bell, and telus all use the same bootloader and modem. The only difference between the carrier firmware is some app customisation included with each ROM.
Kit kat is the last official ROM.
Once the phone is running the latest bootloader and modem, you can flash twrp to install a custom ROM.
Hi! how can I check my firmware version? I want to know if im in the lastest firmware.
and if i flash the same firmware version can I brick my phone? (anti rollback)
Thanks!
