Please can I know something. Have you done something with your SP? If you have, please tell me what you have currently done. If you don't, tell me that you haven't done anything.

So you have unlocked a bootloader. Could you please tell me what method did you used to unlocked your bootloader? Did you use FlashTool or the "fastboot" command in adb?
And based on your first post, I have to say that you have lost your DRM keys. Without DRM keys Bravia Engine won't work.

it was some cmd method i used to unlock my phone, can u plz help getting through 4.1 or flashing my phone to cyanogenmod 11 bcoz after 4.3 update phone is too damn slow , and said me completly new so plz step by step guide is expected :angel: save my butt bro, btw after unlocking is working as it was before slow draining battery as usual

Okay I get you and I have the prerequisites beforehand. Now please confirm your intention. Do you want to use 4.1 or Cyanogenmod?

I can't really give a suggestion. "Best ROM" depends on personal preferences. Since I am currently using CM11, I must say it works really great on my device. However, some people face problem with it such as being it laggy and everything. I hope you won't face the same thing.
Actually I have a guide that will solve your problem.
BUT BEFORE THAT please read everything there. Please follow the requirements. You may ignore any bootloader-related points. Since your bootloader is unlocked, you can skip guide number 1, and directly proceed to the section "Fastbooting DoomLord's kernel" in guide number 2. Then proceed normally afterwards. Get a CM M10 snapshot here. Psst, M11 is getting near!
Now you may go to the guide: http://forum.xda-developers.com/xperia-sp/general/guide-flashing-custom-roms-ultimate-xsp-t2888579

in order to downgrade , should i just follow 1b ??

Yes if you want to downgrade you may just and only follow 1b. However needless to say, if your bootloader is unlocked, there's no more need to backup your TA partition

thank u dude ... i flash my phone to cyanogenmod 11 m10:victory:

Next time, don't ask In general section
There's a section just for questions

Your problem might have be something to do with APN. Just contact your service provider, and get an internet configuration. That will work for you
In Stock SONY, there is an-already method that will fetch internet config. Sadly there's no such thing in custom ROMs.
Or to make matters difficult, you can find someone with the same service provider like you, open their phone's settings, find "APN" in Mobile Networks, and copy all settings hand-by-hand to your phone.

To be able to install CM10.l1 u need to upgrade ur phone to jellybean via LG mobile support tool or LG PC suit , then u need to root it , unlock it and install CWM v 6.0.3.1 then flash CM10.1 zip file .

1. try going into recovery and do a factory reset.
2. if that doesn't help, reflash and all your problems are solved.
do a clockwork mod backup before messing around next time

Use LG mobile support tool, also its "stuck" not "stock"
What are you on? He needs to reflash the rom as he changed the fonts and some may be missing, happens to loads of people, no need for a factory reset, just restore the fonts folder or reflash the rom, if you don't have an unlocked bootloader, bite the bullet, unlock ya bootloader and come over to AOSP in which i would recommend a 4.2.2 ROM.. or do the long winded way of flashing the stock Rom, your all giving some real extreme methods, it doesn't have to be this complicated..

As you followed a guide that just ripped DooMLoRD's work from XDA, you most probably flashed the wrong kernel for your firmware, which is the cause of your problem.
Get the correct kernel from here, which is the source of the guide and files that website is using.
thanks for reply plz stick with me for a sec plz

[Q] Official rom : updates seem to be blocked

Hello, I'm trying to update a Sony Xperia Z (from the phone's menu), but for some reason, the updates don't work, as if they were blocked. From what I've been told, someone tried to root the phone using some random tutorial on the internet, ended up in a bootloop (at the SONY logo), then flashed an official rom (4.1.2 IIRC) via flashtools or a similar software to solve the bootloop. I've checked the bootloader status dialing [*#*#7378423#*#*], and it's still locked .
I don't want to risk bricking it since it's not mine, but the person who owns it really wants to be able to update it normally via the phone (very casual user, no flashing knowledge or anything), so I would be happy if someone could help me ! So, teach me Masters, what should I do ? Thanks in advance !
P.S. : if there's already a post/tutorial about that, I'm sorry but didn't find it =)

As far as I know OTA doesn't work with unlocked bootloader (correct me, If I'm wrong).
Sony PC Companion won't work either, because your friend/you had unlocked your bootloader.
You can relock it, but it won't work either way, if you don't have TA-Backup with your DRM keys, I think

Hello, and thanks for your answer ! I just talked with the person who tried to modify the phone, and actually, he didn't install a custom rom, he just tried to root the phone following some random tutorial, then ended up in a bootloop. He doesn't know if he unlocked the bootloader or not, but to solve the bootloop, he flashed an official rom via his pc (flashtools or something similar), as I said in the previous post... does that change anything ? Anyway, I'm gonna edit the OP to make things more clear.
EDIT : just checked the bootloader status by typing [*#*#7378423#*#*] in the dialer, it's NOT unlocked. =)

Well, that explains everything.
Firstly, you've to download Flashtool (I suggest you to read carefully the information provided in the link) and install its drivers. If you've already done it, you can proceed futher.
♦ I suggest you to go straight to the newest version (4.4.4) Generic. Here is .FTF file, which needs to be put in flashtool /firmware(s) folder (your friend should know it): Generic 4.4.4 FTF HERE
Before start, make sure you know what are you doing and it is only your responsibility.
By flashing .ftf you won't brick your device unless you'll try to flash custom kernel on locked bootloader or something like this.
If you need a tutorial which describes how to flash .ftf, then quote this message and I'll try sort this thing out with you

Awesome ! Yes, indeed, if you could tell me how to do it or link me to a tutorial, that would be very appreciated ! I already have flashtools installed, but don't know the commands, or the right steps to flash something without using a recovery. Anyway, thanks for your time ^^
EDIT : I forgot to indicate that I'm running flashtools on linux, so no interface, everything has to be done with commands lines... so the tutorial in the link in your previous post can't be used with my os, I think !

how should i back to stock ?

hello everyone
i have a rooted n960f device with the alexndr ROM , since iwant to sell the device i want to unroot it and back to stock .
unfortunately when i trying to flash the stock with ODIN my device boot up without IMEI.
in order to fix that i need to ROOT the device again install TWRP and than install te ALEXNDR rom again.
these is the only way to get the Signal again .
do you have any idea how i can back my device to stock ?
thanks
guys ?
any idea?
please
You most likely just need to flash the correct firmware for your device and you do know there is no way to make the device stock again after rooting, right?

It's not a matter of you don't tell me, i don't know.!
It's a "matter" that before you root your device, to familiarize yourself, regarding the pro's and cons
of rooting.
To do research and then if you don't understand or want guidance regarding a particular issue /
"problem" then ask.!
Bottom line is....
no use asking afterwards if you didn't do your "homework" before.!
Good luck.
