Follow the Order Carefully:-
1>remove "preview for Developer " and "windows Insider" apps if you already installed and restart the phone
2>Open the Storage Sence ,Go to "Store new apps on my" option and select 'SD card '.
3>go to store and install " metro commander(free)" ,"preview for Developer " and "windows Insider" app.no need to login in preview app
4>Deploy "CustomPFD_0003.xap" and "WPSystem_Folder_Unlocker_Release_ARM.xap" by using sdk app deployer.
5>make sure all above apps are in sdcard by going Storage Sence. if not move from phone tosd, close all apps in phone, then go offline mode.
6>>open " WPSystem_Folder_Unlocker app" click on "unlock WpSystem Folder" option,you will see success popup and close it

read 5th step twice and understand the proceess, all other manual swap method leads to errors.use metro commander(free) only

5>open metro commander on left side select 'add shortcut ' select sd card and open WPSystem rename "Apps" to "Appx"
in renamed Appx Folder go to {178ac8a1-6519-4a0b-960c-038393741e96} folder you should delete folders one by one by holding it,
press back button then go to {27d6a090-50d2-4337-88cb-41d97597757a} do not do any thing now
all the above process on leftside only on right side you still have "add Shortcut" Option
now Right side select 'add shortcut ' select sd card and open 'WPSystem folder' and go to {178ac8a1-6519-4a0b-960c-038393741e96} which will be empty now
now select leftside click on middle button which is 'sellectall ' icon
it will select all folders at menu 'copy button 'appear then select it
wow all files will start coping from left to right now,wait untill 100%
final step rename back "Appx" to "Apps" and close app
"all process at 5th stage should done at a time without leaving app"
"preview for developer " patched Successfully you will notice icon change
Finally:--
open "preview for developer
goto HKLM -> SYSTEM -> Platform ->"phoneManufacturerModelName" then type "RM-978_1046" click 'write' and
goto HKLM -> SYSTEM -> Platform -> "PhoneMobileOperatorName" then type "000-IN" click 'write'
above values for all indian lumia phones .
close the app and open windows insider go online
wow now you can get " insider fast/slow" option click it, finish it and press phone update through wifi.
