Is it possible to downgrade to different region and older firmware? - Galaxy S6 Q&A, Help & Troubleshooting

Hello, I currently have SM-G9208 S6 on 6.0.1 which is Taiwan model.
The problem is I live in Australia and with Vodafone and their current firmware for SM-G925I is 5.1.1.
The reason I want to use older firmware for Vodafone is to be able to use voLTE.
Currently I don't have voLTE option on my phone.
So can anyone help me out? Also if possible to I need to wipe everything out as well?
Thanks

Is Firmware Region important?

Hi,
I wanted to know if flashing a firmware from another similar region was possible?
For instance I have the g920I from Australia and I noticed that the New Zealand version has been updated today.
It seems that if you your phone is unlocked to any provider you can then flash any firmware but I would like to confirm please?
Cheers

No it doesn't make any difference. I flashed the New Zealand on my G920I and it actually fixed some issues I was having. So it is safe.
If you flash the wrong firmware, you and your phone might start speaking with an accent. I'd recommend just flashing firmware from your region.

Needed 5.1.1 lollipop firmware compatible with a G920IDVU1AOC6 s6 phone.

Hi guys
Can anyone share a 5.1.1 firmware compatible with a G920IDVU1AOC6 s6 phone. Not to concerned with the country or network. Just really need to get lollipop 5.1.1 on my device. Can't find it anywhere and really need the update. (already tried some brazilian and New Zealand 5.1.1. firmware but nothing worked so far as they had other g920i build versions. Needs to work with G920IDVU1AOC6.
Please let me know.
Thanks.

Hi
thanks for getting in touch. I've tried all types of g920i for lollipop 5.1.1 but it seems none of them actually works for my build model. I've only get access to 5.0.2 because the firmwares are exactly the same as my model (g920idvu1aoc6).
f anyone has a solution for me to install lollipop 5.1.1 on my model, it would be highly appreciated. Previously tried some g920f firmware as well, but after going all well on odin, I only get the samsung logo on screen and nothing else. (even deleting the bin files on the original stock firmware). Any ideas? Cheers

G920i running Tmobile firmware?

Can the G920i run the firmware for tmobile? Is it possible for me to get updates from tmobile as well using the international variant? I want to utilize their VoLTE and their wifi calling, I just happened to buy the G920i... was wondering if the firmware for a different model will work
No it can't.

Can I run a stock G920F rom on a G920i?

Hey,
So I've recently gotten an Australian S6 G920i and was wondering if I would be able to flash a G920F rom to it. As far as I know the phones are practically identical so I cannot see why it wouldn't be possible, I just don't want to have to wait for the Australian carriers to update the firmware, plus the bloatware is gross (bootscreen, apps, etc.). Tried to look for a similar thread but couldn't find anything, help would greatly be appreciated
Thanks!
Hi soymllk,
What carrier are you using?
I assume you are on 5.1.1 firmware.
Just took a quick look at sammobile and found Vodafone firmware from 01/14/2016.

You can flash an unbranded firmware on your G920I. Running a 920F firmware isn't possible on your phone.
The only difference in the 920I and 920F are the LTE bands. The 920I has the same FDD-LTE bands as a a 920F, however it also carries additional TDD-LTE bands for Australia, India, Singapore and a few other countries.

Hey guys, thanks for your help! Before I saw any of this I went to SamMobile and flashed the Vodafone ROM (knowing that Vodafone don't customize phones at all, unlike Optus...) so all the bloatware crap is gone now Thanks!
(BTW I'm with Vodafone but the phone was originally an Optus phone so it had all their stuff on it, including a lovely "Hellooooooooo" welcome and "cya ya!!" shut down screen-_-)

Flash Non carrier OS on G920I (Currently Claro Carrier)

I Have a G920I which is branded by an international carrier called Claro, Is there a way for me to flash just the non carrier version of the OS thru kies? I don't have root just want it debloated and Ive already disabled apps but don't want claro showing up upon startup also.
If this is possible, will OTA still work?
Hi,
I think it's safe to install a different country 920i firmware using Odin. I used to have Indian firmware on my Brazilian 920i and it still receives OTA without problems, since the device is still stock.
All the best,
~Lord
