[Q] Changing Region or CSC code and baseband, possible?

Hi, I'm from Asia bought a export set of the note2 n7100. I just got to know that this unit is a Middle East unit with Egypt, United Arab Emirates, Iraq etc... is it ever possible to change the baseband and the CSC code to Asia?
I also noticed that the 4.1.2 software is not out for my unit, therefore I was wondering if I can change to CSC code to an Asia CSC code.
Please advise.
Thanks in advance.
try this: open phone dialer, dial: *#272* your phone Imei number and finish with #
Now you should see many CSC codes for different countries
choose one that you want and save
remember, once you press "save" device will factory reset. So back up your data.
There is also app in the market for this, but it pretty much does what I just explained above.
Back up your data first!!!

I tried *#272*imei# but doesn't seem to have any reaction. I downloaded the CSC Select but I can only choose the middle east countries...
This code won't work on note2
Why you not downloading full rom from region you like and flash using odin

hi, thanks for ur reply. flashing it with odin did came across my mind. but I was just wondering if the baseband will cause any problems. I also did wonder if I were to update using odin to another firmware, say I choose malaysia. nrxt time must I do the update via odin again? or can I use OTA?
thanks for ur advise
there won't be any issue using other country ROM.
If you flash malaysia ROM, you will get update OTA when there is update for malaysia.

cool!
do I need to backup my baseband imei etc?
I recommend only EFS backup and keep on ext Sd as well a copy on PC too
if you want to backup everything ROM including baseband you can make nandroid backup.

Hi Dr Ketan,
My phone is unrooted, can you advise what is the most safest way to backup the phone? Nandroid backup seem to require root access.
without root you won't have much option to backup
still you can use 'My backup Non root' or other similar to backup
-Contact (stock appl itself have option to backup, as well google sync)
-SMS
-Applications (without data, like credential,game level etc, you can just backup apk)

Thanks for your prompt reply.
I'm more concern about EFS backup. I've rooted my HTC HD2 before and restoring the phone was simple. But for n7100, I am afraid it's not as simple as it is.
you needs root to backup EFS
root is just 10 min procedure, and there is no risk if you follow instruction to ther letter

Hi, If I use titanium backup will it be enough?
I would presume that if I would to do nandroid backup I will need to use the "Root with ExynosAbuse apk" ?
At the moment I'm running JB 4.1.1 but I wish to update it to another countries ROM.
Thanks in advance for your advice.
Titanium can't backup efs, it can just backup applications with data
For nandroid backup you need cwm (method 2in my guide)

EFS messed up problem of LG optimus G F180
Can any body held me . I have lost my cell fone service after installing kitkat zip rom V20A of vodafone in my LG optimus f180L. After that I flashed European KDZ back which I was uning previously V10h but after installing baseband I lost signals on my device. no data ne any service . and after inserting sim card my IMEI number shows unknown.. Please held me how can i get out of this problem..
^ you better have EFS backup, because you'll need it to restore your network signal. Each IMEI is unique, located in EFS partitions, so you need a backup of your own partition..You could have done that with FreeGee. NEVER flash any ROM without performing an EFS and modem backup first. I read that you can restore IMEI with a specific software, if you don't have EFS backup, you could give it a try.

If you used new cwm and somehow formated firmware don't worry. Flash your stock ROM back.
Also please double check if you have e975 or f180 or some other variant before doing any more of your stuff.

Dont have
Any other way?
do you have your IMEI? Press *#06#
If IMEI is ok, then try to flash KDZ of respective version F180L through Flash tool 2014. after Flashing , root the phone, make EFS BAckup, then flash " e975 germany kk kdz"... then restore efs.
