Right now I have the 4.0.4 Android( stock version) of the xperia j with locked bootloader and I've rooted-it and I've also installed the CWM.
I would like to install Cyanogen Mod 10.1 but since I have the 11.0.A.7.5 firmware I have locked bootloader and I can not flash it.
My question is if I can flash an older stock firmware and by doing so will I be able to unlock my bootloader?
From what I understand right now since I have a locked bootloader I can only flash stock ROMs so if that is correct than can I just flash an older stock ROM, one that will allow me to unlock my bootloader and than flash CM 10.1 on my Xperia J?
And another question- I know that by unlocking the bootloader I will also loose my warranty but from searching the XDA forums I saw that I can make a backup copy of my stock ROM and flash it to relock the bootloader again. Is that accurate ?
Thanks in advance for your help!
First is your bootloader unlockable. Then you can unlock on any firmware via sonys website. I dont think there's a cm10.1 released for j. If you unlock your bootloader you will loose DRM keys forever even if you relock they will still be gone that's how Sony will know your bootloader was unlocked.
It is not unlockable, that is why I wanted to flash another version of a stock ICS.
Won't that allow me to unlock the bootloader ?
From what I understood right now I can only flash stock Roms with the locked bootloader, is it correct or since I have the "NO" status at the bootloader I can't even do any of that ?

Hi, I have the tipe (ST21i) but with the locked bootloader, and I saw that in a post commenting that can install the CM10 flashed the boot.img.
I be able to do it on my phone using flashtool?
no first you have to unlock bootloader from sony website!
complete guide is provided here on the forum!
then only you can flash boot.img and cm10 rom.
Thanks, but the bootloader can not be unlocked, there is another method to unlock it?
if ur bootloader unlock allowed status is no, then presently there is no way to unlock as far i know. developers are looking for a solution to that!
I have updated Xperia J from ICS to JB. Its bootloader unlock allowed says YES but its not unlocked. The phone is in warrenty. I want to go back to ICS 11.0.A.7.5 as rooting is hard in JB.
I have some questions:
1. If I flash with flashtools, is it necessary to unlock the BootLoader?
2.After flashing ICS, in future If I want to flash JB with Flashtools, will then I have to unlock the BootLoader?
I dont want to unlock BL as the phone is under warrenty.
Thanks....
As far as I know Flashing ftf file using flashtool doesn't require boatloader unlock bro. And it won't unlock your bootlader. So if you flash ics, the boatloader will still be locked. And you can use flashtool at any time to flash jb ftf.
Hit the thanks button instead of telling it....
thank you

Hello, I want to flash my xperia e3 using flashtool to the latest firmware (4.4.4), but all how-to's i read say i have to unlock my bootloader. Must I unlock the bootloader if I plan to flash all generic sony firmware on my phone? My bootloader unlock status says "no."

if you wan,t to flash stock firmware then no need to unlock bootloader.
cause you flash firmware (*.FTF) using flash mode not fastboot(bootloader).
so you don,t have to worry of unlocking bootloader.
ok, thank you for your reply!
So...apparently I can't unlock my bootloader. I've seen that you can root even if you have your bootloader locked, but what about flashing a rom?
Is there any chance to flash a custom rom with your bootloader locked? Not stock pre-rooted rom..
Can´t say if you can unlock bootloader based on what model you have.
Yes you can flash any custom ROM based on Stock ROM on locked bootloader, but you can not flash AOSP roms on Locked BL. For those you need to unlock it.
Hey guys! I unlocked my bootloader keeping my DRM Keys by using this http://forum.xda-developers.com/showthread.php?t=2292598
Now I'm on ZyxxOS ROM and I would like to return to stock ROM, make root and relock the bootloader.
The problem is that I don't know how I can root the phone after flashing the ftf of the stock ROM, can someone tell me how o provide me a link to a tutorial? I've searched and didn't see any around the forum

Flash an insecure kernel. Its the easiest way to root. But in the OP you said you wanted to re-lock the bootloader, then you cannot boot an insecure kernel.
Please let me know if you will have a locked or unlocked bootloader.

Why? You will lose root when you re-lock
Just go back to stock and re-lock then use the massive thread in the general section to root.
Also, that rooting method works on unlocked bootloaders as well. Anything that works on a locked bootloader works on an unlocked bootloader as well.
