unlocked P768 bootloader before ?!

Hi all,
I did upgrade the 768 to official jellybean (mexico) and has been since trying to unlock bootloader and root but in vain!
all tools or command I use just restart my phone instead of prompting me to press VOL_UP to unlock. I have read about putting phone on (LG mobile/ charge only) and leaving phone running vid on wifi for 30min, but still I get the same result.
So I am here asking if anyone unlocked the 768 before? What exact steps did u do?
Before anyone asks: yes USB debugging is enabled and drivers are installed.
I hope you can help me! thanks!

Telce Mexico LGP768G V20A kdz isn't unlockable. Try Vietnam LGP768 V20A kdz , you definitely should be able to unlock your bootloader on it.

if you wish to root , you do not require unlocked bootloader.

Look amigo, from what i understand you require to unlock the bootloader only if you want to install custom Roms on your phone and as far as I know there are no such custom Roms for our model p768 because of the 8mp camera, además you dont need to unlock the bootloader to succeed rooting your phone.
I have rooted my phone and did not unlocked bootloader, what i done was reading a lot this 2 guides:
http://forum.xda-developers.com/showthread.php?t=2173465 with this one start following instructions from step 0)
http://www.htcmania.com/showthread.php?t=537162 but since your native language is spanish I recomend this one guide better!
Anyhow here is my email [email protected] and if you like you can add me on skype with this email [email protected] I am Mexican and be more than glad to help rooting your phone.

Correct you are amigo, but what i have read is that if you install a custom Rom for p760 on our devices p768 the camera will stop working, so many have tried and cuz of that they went back to stock Rom, do you know if that issue has been solved. ?

Guys, do you anyone that has succeded?, have you read about our devices p768!?, the question remains, what is the point of unlocking bootloader if there are no custom Roms for our devices!!??, I havent read or heard from anyone that they have succeded installing a custom rom witho loosing the camera of the phone, are you willing to sacrifice the camera of your devices!?, there is a way to unlock the booloader of our devices ny the way, it involves going to a stock Rom version that allows BL unlocking and then back the the proper version or the custom Rom , but again and again "8 mp" camera will not work, at least thats what i have read here and there.

I had the same problem. I never could find any update. I don't know what is responsible for it but you should simply use unofficial ways of update like offline update with KDZ.

Xperia M4 Aqua Stock Flash and Recovery

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

Locked Bootloader SOV36

Hey Guys,
I don't speak really good English but I will try my best to describe my problem because I really need your help.
I bought a XZ1 with Version SOV36. The bootloader is locked. Also if I look in the Service Info via "*#*#7378423#*#*" it's written "Bootloader unlock allowed: No". I activated the OEM Bootloader unlock in the developer options but I don't think that this will have any impact.
I need to install any standard Rom without the massive bloatware i got on this phone. A lot of it is not deactivateable. I tried to install a custom kernel but i can't get into the bootloader. So I also can't install twrp or magisk or root or anything else. I found the device via "adb devices" but if I run "adb reboot bootloader" the phone reboots with black screen and a blue LED. No further commands are working or getting any connection via adb after this happens. I tried a lot of ways written down in this forum how to get it done but none of them worked.
The Build-Number is:
47.2.C.1.126
Kernel Version:
4.4.148-pref+
#1 Tue Sep 17 10:47:56 2019
Security patch:
1. October 2019
Thanks a lot for your help!
As it is the "odd ball" version of the XZ1 and the Service Menu says no to the bootloader being unlocked but maybe some one will pop in with a bit more info..
But in the meantime have a read over here.. https://www.liberamenteweb.it/en/gu...ed-apps-from-android-9-sony-xperia-xz-premium , it will help you with your bloat ware issue...
and have a look here.. https://forum.xda-developers.com/xp...devonly-exploits-temp-root-to-backup-t3795510
For others which may have the same problem:
https://king.mineo.jp/my/kangetsu/reviews/item/35887
Here you could find a list of packages you need to uninstall if you want to completely remove the AU-Bloatware.
I'm still looking forward to a solution which could help to unlock the bootloader but didn't find one yet.

I got a unit too recently. My tethering and volte is disable outside Japan. I wondered if it is an au kddi problem or my network. I have not installed bootloader on any unit for some time. It is possible with this model?

I have SOV36 with bootloader unlocked. You have to check if bootloader is unlockable. I hope this helps.

Try downgrading to first version of Pie for SOV36. I unlocked on when it was on first version of Pie. Give that a try.
