Need Patch For My W850i...

Good day to you all.
This is my first post in this great forum and I believe I will get the required information from you guys.

Here is the log of my [hw]W850i[/hw]

16:46:27| EROM Color: Red
16:46:27| IMEI: 3xxxxxxxxxxxxx
16:46:27| Phone ID: [hw]W850[/hw]
16:46:27| Region: M_EAST_N_AFR
16:46:27| CDA: CDA102568/109 R5A
16:46:27| Firmware Version: R1ED001
16:46:27| EROM: R3A016
16:46:27| Ready for operation!

First of all, I am happy with my [hw]W850i[/hw], and nothing wrong with it regarding its operation. I don't have enough background about the firmwares, custom packs, EROM, etc and all the things related to firmware patching, but I am reading through the forum and I am learning.

What I want to get is to set a password on Messaging folder for privacy.

When I connected to XS++ v3.1 it asked to update the CID to 52 and I didn't apply it, because I am not sure what will happen next,

1. Am I going to lose my phone languages, which are
M EAST N AFR (English - Arabic - Persian-Farsi - French), please advice.

2. In case of any problem and I wanted to flash the firmware am I able to flash the following firmwares with RED49
W850_R1ED001_FS_M_EAST_N_AFR_RED49
W850_R1ED001_MAIN_GENERIC_CY_RED49
because I couldn't find RED52 for M_EAST region only I found the Main
W850_R1ED001_MAIN_GENERIC_CY_RED52
then if it's not possible to flash with RED49, and I have to stick to RED52 for flashing and FS is not available for M_EAST, then which FS should I use and how can I bring back the Languages specified above?
FYI, I could get the Custom Pack for my region
HB1-06_Gen_CDA102568_109_R5A_GENERIC_M_EAST_N_AFR

I suggest you to update to CID52, then to flash with:
W850_R1KG001_MAIN_GENERIC_CY_RED52
W850_R1KG001_FS_M_EAST_N_AFR_RED52 and customize with
HB1-06_Gen_CDA102568_6_R5A_GENERIC_M_EAST_N_AFR, because you'll find the patch you're looking for W850_R1KG001_enable_password_protection,among many others.

I've flashed my W850i to R1KG001 successfuly, great great the phone is working just excellent.

Thank you this was really fast.
