FIND YOUR SPECIFIC GUID HERE!!!
[HKEY_CURRENT_USERSoftwareBlueStacks]
“USER_GUID”=”SOME-NUMBERS-HERE”

Example of a GUID:
“USER_GUID”=”8dfcb602-4b7d-11e1-9dc9-f3dea6cb4293”

Example of a modified “BootParameters” with correct GUID and changes made to mount /system:

ENTER-YOUR-GUID-HERE must be changed in 2(two) places in BlueRegistryMOD.reg

THIS IS THE PROCESS:
Make sure to exit BlueStacks before proceeding1. Paying attention to the guidelines above, place the following files in their correct location – this includes initrd-betahack.img, ramdisk.img, and system.img.
2. After finding your GUID and making the appropriate changes to BlueRegistryMOD.reg in 2(two) places, run the registry file.
3. Start/restart BlueStacks – go to the Start menu>type Start Bluestacks
4. Start adb on your computer

To start adb download the ADB zip file and extract it to your desktop. Then open the folder you have just extracted and then Hold SHIFT and then RIGHT CLICK mouse button or press APPLICATION KEY. Then click 'Open Command Window Here'. After that type these commands one at a time and press enter for example

Type adb connect 127.0.0.1:5555 and then press ENTER, then the next one followed by ENTER and so on.
----------------------------------------------------------------------------------------------------------------------------------

adb connect 127.0.0.1:5555
adb root
***You should get message: “adbd is already running as root”***
adb remount
adb shell rm /system/xbin/su
adb push su.x86 /system/xbin/su
***su.x86 must be copied in the ADB folder you have downloaded and extracted above. ***
adb shell chmod 6711 /system/xbin/su
adb shell mount -o ro,remount t-ext4 /dev/sdb1 /system

----------------------------------------------------------------------------------------------------------------------------------

Exit adb by closing the command window
Restart BlueStacks – go to the Start menu>type Start BlueStacks

At this point you should have root and read/write access.
Verify root using a tool like Root Check. I suggest Root Check Pro because it will point you to what the problem is if you do NOT have root.
Verify read/write access using a tool like Root Explorer.
Enjoy.
