K810i Debranding Help

I have a Sony Ericsson K810i with the current Software information:

R8BA024
prgCXC1250902_ORANGE_SM R8BA024
EROM: R3A022
prgCXC1250616_EROM_DB2020_HB106GENERIC_FOTA_SIMLOC K_FLAFLA_SIBLEY_SEMCUSB

Customization:

CDA102779/54 R5A cxc1250813 R8BA024 ORANGE_GEN

It is already unlocked, but it is still branded on Orange Romania.

I wish to debrand it using:

XS++ 3.1
Flash drivers: SE-lifestyle USB Flash Drivers
K810_R8BA024_FS_CENT_EUROPE_RED52.fbn
K810_R8BA024_MAIN_GENERIC_SM_RED52.mbn
HB1-06_Gen_CDA102568_2_R8A_GENERIC_CENT_EUROPE

My XS++ told me that I have:

DB2020 CID52

and the log:

Questions:

1. Is it safe to use these firmwares?
2. Must I use the customization or can I just do it without using it?
3. Using this will I have romanian and english languages?
4. Are the firmwares that I chose, the best for my phone, or are there any better ones and which are these?

If you have some download links it would be very helpfull.

Thank you very much for your help.

your files are safe, it will work, about the language you will have english, Czech, hungarian, polish, slovakian
if you want Romanian and English use the following files
K810_R8BA024_MAIN_GENERIC_SM_RED52
K810_R8BA024_FS_MEDITERR_RED52
HB1-06_Gen_CDA102568_4_R8A_GENERIC_MEDITERR
you wil find it in the download section

After I will do this debranding, will I be able to use SEUS in case a new firmware is out for my phone?
Will there be any trouble or things I have to look out for, like getting it locked again or getting it branded again?

Thank you very much for your info, you have been the most helpful person yet.

yes it may get sim locked again and rebranded and then if u use seus it will have a cid 53 which mean u will have to use jd flasher :( just stick with what u have got for now and try to avoid seus

i have a k810i with CID53, also branded in orange romania...tried to flash it with mediterr in JDflasher but it didnt debrandit, and cid is still 53...anyone know how i can downgrade the CID back to 52?

use this but u have to pay there is no free way to debrand unless u have a se tool box then u can test point it Top Sony - Buy Ultimate Unlocker LOGs
