Which stock firmware should i flash? - Xperia Arc Q&A, Help & Troubleshooting

I am using LT18i (arc s) with
SI:1261-6337
Phone soft version: 1253-8238 Generic-user
File system: World .62
Cust. ver: 1254-2261
bought from Bulgaria but not branded. When I checked i saw that these numbers are Generic Trade Switzerland but on my box is written FR, DE, IT, but SI numbers for Central Europe are different. So if want to flash a firmware which one should I use - Generic World, Switzerland, Central Europe or? Is there any difference at all and which is best option for saving the warranty?

Either central europe or generic world... either way you can always go back to your original FW if something goes wrong

Go for world generic!
Most probably all the versions just include some bloatware and additional languages!

Ok then, but if I have to repair the phone in a service they will notice that I have changed the firmware. I want to root it but I have to flash .42 firm and then .62 again but how can I go back to may original firmware without recovery? I will be able to make a copy after rooting but then firmware won't be my original.

[Q]SamFirmware Download ROM advise?

Hi,
so my local is UAE, when I went to download the firmwares (For removing the "modified" thing), I found two versions, LYS and XSG. both of them have a PDA number different than the other, so I didn't know what to get, then I checked my phone and found this:
Baseband version:
N7100XXDMF1
BUILD NUMBER:
JZO54K.N7100XXDME6
Then I checked the LYS and XSG and all of them end with DMC/DMB
Then I checked the United Kingdom BTU, and I found the same as LYS and XSG, with the addition of DME6 (my mobile). Which I found weird cuz I bought my phone from the UAE, and it was an international version.
What I wanna do is roll back to a previous update, run Triangle Away, reset my status to Official, then update again.
How come I have the UK's update (I updated IN THE UAE), if my phone is from the UAE? or does the Build number don't matter which country I'm in?
One more question, If I flash the ROM via Odin, what am I risking? (phone brick, app loosing, data loose...etc)
thanks

any reasons?
XSG is country code for UAE
Another way to move back to original stat
-Open kies - tool - firmware initialization - follow wizard
But this way you lose data.

but how come I have the BTU update? also LYS is also UAE, Du maybe?
If your device have BTU rom then you will get updates from btu only. Probably when you have purchased rom you may have btu version installed instead of UAE.
What you are getting by dialing *#1234#

if u don't have EFS backup u will end up with fake imei if u go back to DMC3 from MF1 so maybe the network wont work

Your device country code is written next to the serial number on the Retail Box.
I would suggest that you stick to the rom which belongs to your country code to avoid any problem that may be caused by loosing your EFS data.
If your are not under warranty, it does not matter which country code you are using any way.

First, on the Box I found samsung.com/fr , which means the Mobile is French. So I went to sammobile, searched France (XEF) and found the CSC and PDA, and when I run in my phone *#1234#, I get the CSC and PDA which are the exact same as the French XEF 4.1.2 update.
So that means my phone is french and I should install French Versions...Guess this is why I got the 4.1.2 update not available in the uae.
That i already said, if your device have other country rom, you can update from any place when installed country version have updates. Match all three,
Ap, cp and csc
Sammobile zip file have only pda and csc mentioned but when you extract it, tar file will have all three.
Just download. 1-2mb and explore it with unzip to find full name.

Rom Flashes but won't change Help pls

Problems changing Rom
Hi guys I seem to be hitting a problem. I have a d855 uk version of he g3 branded to Vodafone uk.
No matter which rom I install it will always stay the same branded version. For example if i flash euro 10A it will become a Vodafone version of 10A not the generic euro version. I have tried uK specific kdz and euro ones, even tot files the same thing happens it will downgrade to the version of my carrier specific rom.
I don't know what else to do it flashes ok just never makes it stock with no carrier branding. Any ideas. Thanks guys.
Tried flashing some prerooted stock rom through recovery?

[Q] [SM-T800]Can I flash stock firmware via odin form diffrent country?

Can I flash stock firmware via odin form diffrent country?
I have bought tablet in US. Now i want to gift this tablet to my brother, but he only speak in polish language
So I have SM-T800 with T800XXU1BOE2 firmware. XAR region.
I want to flash T800XXU1ANEB_T800XEO1ANE2_XEO via odin.
The reason for this change is lack of polish language in my current firmware.
Thanks in advance
Yes as long as the bootloader isn't locked and the roms use the same platform, ie exynos or Qualcomm.
However there may be issues with mobile data.
This is Wi-FI version, so this problem doesnt concern me. i think bootloader will not be a problem to unlock.
How can i check platform in firmware i have downloaded? (from sammobile.com for sm-t800 model, there was 3 diffrent i have picked the one with kies icon enabled).

You wont be able to unlock the bootloader, but no worries you have the exynos wifi version so you dont have a locked bootloader anyway.
No Point
Just flash the U.S. one and change the language to Polish

O2 branded SM-G960F to vodafone

I've got an O2 Galaxy S9 and I'd like to use it with a Vodafone SIM in UK.
Is it just the firmware that would need changing or would the ROM need to be changed too?

the firmware contains the ROM, but the ROM wouldnt have been what prevented you from using this to its full potential. Technically, all youd really need to do is flash your carriers CSC and even maybe the HOME_CSC. If youre unfamiliar with those terms and/or processes, just flash the Vodafone firmware with the CSC (which will factory reset it) and call it a day

Hi Youdoofus,
Thanks for your help.
Can I just run this past you then.
The phone came brand new from O2 and is not locked to the network.
I'm using a Vodafone SIM in the phone and I have trouble receiving SMS, making 4G calls, etc.
I understand what it is to flash the phone with new firmware although I've never done it before.
If I flash the phone with the latest Vodafone firmware and Vodafone or generic CSC that should be enough to get the phone working ok with the Vodafone SIM?
Sorry if the question seems basic. This is obviously not my area of expertise.

no worries mate. nobody is innately knowledgeable about this stuff, even the seasoned linux vets can stumble about a bit.
but yes, all you really need to do is flash the Vodafone or generic/multi csc and youll probably be good to go. the reason your sms isnt working is likely due to your APN settings and voLTE wont work without your carriers own CSC installed tho. That being said, many of the multi CSC firmware packs will do the job quite nicely as they will likely have Vodafones CSC in their list of available CSCs. It would be different if you used a fly by night carrier
I flashed mine with unbranded generic UK firmware BTU-G960FXXU7CSK1-20191121174240.zip.
Got it here, took forever: https://samfrew.com/download/Galaxy__S9__/5vgs/BTU/G960FXXU7CSK1/G960FOXM7CSJ5/

Big fan of this Lineage 17 10 rom by Abtekk if you fancy something custom:

Currently running that with White Wolf kernel & Zoran's GCam, good luck!

Question about flashing a stock KDZ rom from a different region

Hi all, I currently have a G7+ with the model number LM-G710EAW. From this site, there's a few EAW's that get the android 10 update, that is the HK, KR, and SEA. To this day, my phone is still on Android 8. Since that the only way to check the phone region via IMEI is now gone, I have to assume that my phone's region is IDN (I bought it in one of Indonesia's domestic store). With that, I have a few questions
1. Is it safe to flash a SEA KDZ to a IDN phone? Is there any possibility of bricking it?
2. What about the baseband compatibility? Can I still use the cellular network?
3. Is there another way to check an LG phone's region?
Thanks in advance!
