How to install a Custom ROM on a SONY ERICSSON or SONY mobiles !!WORKING METHOD!!

I know you people might be concerned with your Sony mobiles since Sony stopped providing us updates and we feel abandoned  so here's a simple way how to use a custom ROM on your Sony device. I installed a custom ROM in my Sony Ericsson WT19i and it works perfectly here's all the information about how i did it and its pretty easy too.

So before beginning i want you people to download some of the stuffs like:
1. SDK manager 
2. Fastboot drivers and device drivers for sony
3. Eroot
4. Flashtool(Search it on Google you will find it if you didn't and need it so badly comment about it i'll upload it )

NOTE:So what you are going to do is on you are own and we are not responsible for any damage caused and this will TERMINATE YOUR WARRANTY so proceed on your own risk.

 You need to install SDK manager and install Google USB drivers after you do so make sure you copy and paste the Fastboot driver and your device driver into the Google USB driver folder it will be somewhere in C://.... sdk/tools/usb/ somewhat similar to that if you do not install these drivers it is gonna cause you a lot of trouble

First step:
You need to root your device this is required for the software to manuplate with your device and its completely safe and easy. So How to do it? Before you start you need to make sure that the USB debugging is ON else you wont be able to do any of the stuffs. So All you have to do is open Eroot software and just click on root it will root your device in few seconds

Second step:
After you root your cell phone you need to unlock your bootloader if you dont then there is a risk that you might brick your cell phone don't worry its just a soft-brick and it can be solved easily. To unlock your bootloader you need to install the flashtool (developed by Doomlord A very big thanks to them) after you do so go to the drivers folder of flashtool directory (C://....flashtool/driver) install the flash tool drivers again just to make sure everything goes fine. After you do install it open the software  click on unlock bootloader now you need to connect your device in flashmode to do so you need to turn off your cell phone and hold your physical back button and connect your USB cable a green light should blink ,Ola its done (Note If you do not have a physical back bottom try  *FOR 2011 models Volume down button
*FOR other devices Volume up button if this doesn't work search on Google)
Now please Copy the PIN and IMEI number somewhere safe you might need it in future

Third step And Final step:
After you do all the above stuffs you need to find your self a ROM for your device just search it in XDA developers you will have a plenty of ROM's after you download your ROM (you need to copy a zip file in your SD card That's if anything goes wrong to recover). Now unzip the file you will have something like BOOT.img just copy it to your desktop just to make it easy to locate the file. So now open the Flashtool again select flash in fastboot mode and connect your device now click on Reboot into fastboot mode(via fastboot) your device will go into fastboot mode now click on select kernel to flash under it now locate your Boot.img file. it will take a bit of a moment BOOM!

NOW you have successfully install a custom ROM into your device. thank your for taking a moment and reading this and if you have any doubts or trouble with the process feel free to comment I will be there to answer it
