How to install Mango (beta) in your WM7 phone (ver 7712)

Finally, I did it. I installed mango beta in my HTC HD7. No doubt this is a great great leap forward for microsoft. But still we need much much more... 


How to install it? I will explain the process. but - I won’t be responsible if you end up damaging your device. Make sure to follow the steps without fail. Because i was able to install mango beta without any issues by following these steps. 


Let me thank windowsphonehacker.com and addictivetips.com for this. 

Requirements:

1. 1. You must have at least 60% battery remaining in your phone. I completed the entire process by having less than 50% - but its recommended to have 60% or full battery.
2. 2. Remember that the minimum hardware requirements for Mango beta are the same as Nodo (the last official update to microsoft - which gave you cut-paste option). If your device only supports pre-Nodo versions of WP7, then this procedure is not for you.
3. 3. Go to this page, and download the file.

Instructions:

1. 1. If you have a 32-bit system, go to this link, while for 64-bit, here. Download the tool suite provided on the respective links.
2. 2. Install the developer tools you just downloaded and then exit setup.
3. 3. Now we turn our attention to the “Mango For All” tool downloaded in step 3 of our requirements. Unzip the file if not a zipped, just copy the four contents), and save the unzipped contents to your system drive (c drive).
4. 4. Using your phone’s USB cable, connect to your PC. This will automatically open up Zune. If not do nothing. 
5. 5. If Zune opens up, Exit Zune without doing anything.
6. 6. From the “Mango for all” folder, run “update.bat” file. This will open up a series of option screens, follow the instructions that do the following for you:
   Create a backup of your phone
   Provide your with enough rights to update to Mango
   Save your backup copy in the “Mango for all” folder (will take approx 600 secs)
7. 7. This will open Zune all by itself, and you will get an update notification. That’s the Mango beta. After you apply it (update - 1), and reopen Zune, you will see again an update visible there (update - 2). This is the sought-after Mango beta 2. Install this and you now have Mango beta 2 on your WP7 Nodo device! (approx 20 - 30 mins) 

Important:

You must restore to NoDo before the Mango update is released, according to Microsoft. This applies to everyone, including registered developers.


Restore NoDo
To restore NoDo, run the Restore.bat file, or follow the instructions in Readme.txt.


Do not, at any cost, delete the premangostate folder in your C Drive. This is required to restore the Nodo version - once mango is officially out. 


Update: Your Zune will not detect the new mango OS. You have to download and install New Zune for Mango form here. Both old Zune and New Zune can be installed side by side. No problem.
