Is there anyway to get an unlocked bootloader? I am still running stock nougat with bootloader v4. Can I flash G930U and unlock bootloader that way? I really just want to install custom ROMS. I have no need for regular root.

Does the bootloader update when you install a new version of a stock rom such as 2.3.4 or how do you update it?
No, once you unlock it, it's going to stay unlocked unless you do a fastboot oem lock
There is no such thing as updating the bootloader
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 ?
Hey guys i was just wondering if there was any way to flash back to stock without loosing my bootloader unlock?
the only way to re-lock the bootloader is by using the fastboot command for it.
This is an interesting question.
I am currently on the latest 4.4.4 and now I would like to try CM 12.x (5.1.).
In case I do not like 5.1, how do I get back to stock without losing the unlocked bootloader?
flashing back to stock will not relock your bootloader. the only way is by fastboot command. so if you an unlocked bootloader there is no need to worry about losing that. you will however lose root which is easy to get back.
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.
I'm trying to flash a stock rom on my phone, but it doesn't work. I unlocked OEM unlocking and don't understand why it's not working.
