Stock from Future 3.0 and Drake v1 or CrossDL error topic

Here is some guide as i faced problem to go back once from future 3.0 and the other time i installed drake v1 and it changed to d838 so when i tried to install tot it gave me error like crossDL so i figured it out after alot of search how to go back to my stock and now want to share with you people. It my own effort so if you find out helpful then plz appreciate.. thanks.

Steps to follow:
1. Download Winhex software: https://mega.co.nz/#!IUFnRRBb!JlQpWk...-slT0A3W7ARpMc

2. Extract it and open it and there will be folder inside winhex. its pre-installed app so you don't need to install it just open folder and run the application and it give some message that you can save larger file with evaluation version.. just open and click on help and then register option then a dialogue box will be opened and past the key you will find in the main folder text file named with "key". it will be registered version now you can open your tot file and edit it.

3. Open your tot file and click on edit and then on find then search for word "F350" and you will be there. Just change the last word with "L" if you want to go back from future 3.0 rom and change whole letter with "D838" and remove last digit by putting 00 on left column. you can see the pics for guide.

4. Now save the file and with this file flash your lg g pro 2 and for that i m sure you guys already have guide to flash tot file otherwise you can search for it..
