Hello
I'im from France with a SGP311 XTZ. I bought a used one with Cyanogen mod already installed. I'd like to back in stock version but i dont where to start. Is it possible ? Do i need a specific french SGP311 firmware ? Is there DRM problem with bootloader ?
Thx for your help
Since you bought it with bootloader unlocked already, you probably don't have your DRM anymore. However, to go back to stock, just flash any SGP311 fw with Flashtools, any version you want.
Ok thx. What is the matter with having no DRM ? I can't relock bootloader and avoid my warrantly?
You can relock and have your warranty back, but DRM were lost once you unlock your bootloader. You can't restore it from another device, because if you do you will end with a huge paperweight

Hi all, coming from IOS I find all this rooting / bootloader unlocking etc quite confusing as apparently there are some restrictions when wanting to go back to the stock (non-rooted) rom.
So here is my question:
I know relocking the bootloader is quite a specific job, I won't touch that.
As far as I know, if you only want to root the stock rom, you don't need to unlock that bootloader. Is that right?
As I'm on .62 with my mini pro, I need to downgrade to an older version, root it and then do an OTA upgrade to .62 again. I will keep my root then.
My question is: can I revert to a non-rooted version easily?
I still want to be able to test the upcoming ICS version.
I don't want to loose DRM etc, but as I understood this has nothing to do with rooting your device, only with unlocking the bootloader. Right?
Can this be confirmed?

No, you dont need to unlock yout bootloader yo get root. Rooting your device will have to affect with the bootloader and DRM is only removed from unlocking the bootloader. You can easily un-root your phone if you use Doom Lord's root method as he gives a file to unroot.
Thx for the info!
Or you can flash .58 firmware again and root will be gone,
Hello, I want to know how I can unroot my cell phone but I don´t understand when you say something about "Doom Lord's root method". I couldn´t find this in the forum. Can you tell me something about this method? Or can you explain me about how to unroot my Xperia Mini Pro.
PD: I am from Argentina and I have a SK17a.

i'm just posting to say that i'm hoping somebody answers you, because i hate the upgrade as well. it's not an upgrade. sony took their nice, well thought out UI enhancements (pretty much a first for an OEM in the post-gingerbread world), got rid of half of them, then ruined the others.
i am seriously disappointed in the hack job they did. sony did such a nice job with their skin on 4.1.2, why on earth did they need to ruin it? Their notification center was better than googles new one, especially for a tablet!
ugh.

1 - They should both work, I flashed mine with an older version without issues.
2 - Flashing your device with an FTF will NOT affect your bootloader status, in other words...No your bootloader will remain locked.
3 - Flashing an FTF is a Sony original firmware so no your warranty will not be voided, although I wouldn't declare that you flashed it with Flashtool. Unlocking your bootloader will void your warranty. There are ways to relock it but I don't know if they will be able to tell.
4 - No, downgrading doesn't break anything. Unlocking your bootloader will break Bravia engine so in order to restore Bravia you need to backup your TA before unlocking it.
5 - I was using build 370 so as long as you use the one for your device, you will be fine. (SGP312, WiFi Only)
6 - From what I know, the WiFi model only had build 370 on 4.1.2 and now build 136 for 4.2.2
7 - Yes, that is a good tutorial for using Flashtool, they are using it to flash an Xperia phone but the same applies for the tablet, just select the appropriate file when flashing obviously.
Good Luck! :highfive:

Why do you want to relock? Why don't you just leave it like that and use DRM restoration fix for kitkat?
BTW There is official Lollipop and you still use kitkat..I don't understand.

Hi everyone,
I want to buy an Xperia X. The version I would buy (F5121) is branded by an Italian carrier (TIM). Could I install an unbranded stock rom on it ? Do I need do unlock the bootloader or something, voiding the warranty? I'm asking because I would like to receive software updates as soon as possible.
Thanks everyone.
You can use flashtool to flash any stock rom you want. No need to unlock bootloader so you wont void warranty

In case of problems in the future, could I bring the device directly to sony with the unbranded firmware (FULL STOCK, NO ROOT AND LOCKED BOOTLOADER) or do I have to revert it to the original stock branded firmware? I'm afraid that thay could maybe refuse my warranty.
Thanks

the last time I returned a sony phone I relocked the bootloader and flashed a stock ftf. It was no problem. Dont think it matters if its branded or not
Hello guys!
I have a Sony Xperia M4 Aqua E2303 from Orange with their custom firmware.(Their Apps and start-up logo, etc.)
It is possible to flash the sony stock firmware(marshmallow) to get rid of this custom firmware ?
Also after flashing the stock it is possible to install a custom recovery like TWRP?
If is possible to do those operations ,is there a way to back up the actual firmware in case of possible problems?
Im kinda new to this forum but i want to thanks in advance for your help and advices .
Thanks again and have a good one !
If you bought it from Orange, check that your booloader is unlockable (to do this, type this in the call menu: *#*#7378423#*#* then in Services info, rooting status you can see it)
If it's unlockable, you can flash recovery and root it after you unlock the bootloader (You will lose your DRM keys)
Here is a guide about rooting and unlocking.
With root, you can also remove those apps that you want.
(the guide is made for E2353, idk if the files will work for you...)
Also, here you can find the stock roms.

Thanks for your help buddy.
Unfortunately the bootloader is not unlockable.
But i took the risk and i flashed a stock firmware (E2303,Central Europe 1, 6.0.1) via Flashtool and XperiFirm. I got rid of all orange apps except one which is good ,my free space is around 4gb from those 8gb. Also the phone is more faster in menus and some apps.
I saw a thread here on xda , about rooting and flashing recovery with locked bootloader but need to downgrade to lollipop Here. I do not not know if it is worth the while.
Is there any way to unlock the bootloader even if it says that it can not ? Maybe Sony Support?
Thanks again ! Good Day !
Your welcome, also i sad to hear, that you can't unlock your bootloader Have a nice day
