Restoring the stock firmware. - Sony Xperia M

Ok, this might be a dumb one, but not necessarily.
So I've unlocked my BL, and being the stupid twat I am did NOT backup the drm keys. Flashed custom kernel and Cyanogenmod 11.
Now, I'll probably give the phone to my mom and buy me a new one. And she needs it stable. So what are the steps to safely restore the original 4.1.2 firmware?

Just flash the 4.1.2 ftf through flashtool

Yes flash ftf file

But a nandroid backup would contain personal (and sensible) information... that's not good to share...

nandroid backups of the stock ICS firmware 4.0.4

do I need root to slash stock rom?

Do I need to root my phone to flash Stock roms via Odin? I want to flash the Stock rom and I wonder if it gonna lose the IMEI? thanks guys
Nope. But you do need root to install a custom recovery like TWRP or CWM. There may be another method but im not familiar with it at the moment.
Anyway you can easily dl one of the stock firmwares from samfirmware.com and install using odin. Provided you just want pure stock.
And you shouldn't have to worry about losing your imei flashing stock with odin. I dont recall that ever hapoening. Besides, imei issues have been solved. Just check the dev section for info.

thanks for your reply
btw, I'm on stock with latest Tmo update now. Let say I want to flash stock without that update (stock before the update). how does it change my stock recovery? is the recovery still the stock with latest Tmo update?
I dont really understand how the stock recovery works. after I apply the update, is the update applied to the stock recovery too?
As far as I am aware it will rewrite your stock recovery back to whatever version you are installing as well. So long as you use odin and a full firmware file from Samsung.

ROM flashing

Hello experts ! i the unlocked version of the note 2 n7100 and running android 4.1.2 stock rooted with CWM recovery i downloaded pheonix 15 custom rom did a full wipe and flashed the rom but the phone gets stuck on samsung galaxy note 2 screen then reboots directy into recovery! what am i doing wrong ? should i flash MJ5 bootloader in odin before ?? and when i restored my nandroid backup the cellular didnt work until i flash ariza patch to get my imei back ! plz help and thx in advance
Yes, flash the MJ5 bootloader to avoid any problems. And make sure that you have the latest CWM version. I personally recommend TWRP, latest version also. You should be set with that.

Yes.
You may even take a backup in CWM before flashing CM 11 and then restore it so no need to flash through flash tool
Does the backup store in the SD card?

Half yes. Half no.
If you take cwm backup then you can simply restore it back to get your settings and apps back. Then if you want stock kernel flash kernel only through flash tool. So you have a stock ROM along with your saved settings.
When you want complete stock same as when You first started it then you need to Flash full stock ROM, wipe data and cache and relock bootloader.

[Q] Question about Recovery

I'm on stock 4.3 rom & recovery + rooted. I want to flash ND3 kitkat rom over Mobile Odin.(to avoid flashing kitkat bootloader)
So ,my question is - Is it necessary to flash custom recovery(like philz) before flashing Stock rom from mobile odin?
Or it is not necessary?
Any Suggestions....

If your on stock 4.3 then flashing a custom recovery will trip knox as you will have a bootloader mk4 or newer (I would guess mk9) so if your attempting to keep knox at 0 then you would have to flash a Stock rom with odin, why don't you want the kk bootloader?

My knox bit is already voided 0×1
My bootloader is ML4.
& I heard somewhere wifi/battery performance degrade due to kitkat bootloader.
If I'm satisfied with 4.3 bootloader then why should go for kitkat bootloader.(offline charging is not deal breaker though ).
Btw,Anyone knows there, is it necessary to flash custom recovery before flashing Stock rom via Mobile Odin?

How about you install a custom recovery and flash dr ketan's pre rooted dedoxed deknoxed ND3 rom ,it's same as stock without bootloader and no mods.As far as flashing any stock rom one doesn't need to have custom recovery that's the whole point of stock rom you can flash it whenever you like irrespective of being rooted or not and can be done via pc odin or mobile odin.(mobile odin doesn't flash the bootloader).You only need custom recovery when you're flashing any ROM as a zip file. (as the case would be in dr ketan's rom or any other custom rom)
Solved,
