Ahhaa .. Okay.
Here is what cLK has over MAGLDR:
1- Android Native functions (fastboot, adb, reboot into .... )
2- No "GO GO GO" screen, from your splash1 directly to android's splash2 (makes it look more official
But MAGLDR has the following (not all features, only that would be useful to you):
1- Can boot Windows Phone7.
2- Supports RMNET data connection. (Simply, in cLK your data may drop and you need to airplane mode to get it working again, in MAGLDR this won't happen, although I've never faced not even one data drop in the past 6 months)
Anyway .. here are the procedures to install cLK if you wanted to try it out:
1- Make sure you have google drivers installed.
2- Juice up your phone to above 60 percent battery, then connect your phone in bootloader mode. (VOL DOWN + BOOT)
3- Download HD2 NAND Toolkit.
4- Open it & from bottom panel choose "Task29" and go through the process.
5- your phone will reboot, hold volume button to go to bootloader again.
6- now from top panel choose "cLK repartition" and from right panel choose desired system & cache partition then hit "Repartition" from bottom panel.
7- after going through the process, your phone will reboot, don't hold anything, let it boot normally.
8- you'll be welcomed with a little texted screen on your phone, on your toolkit choose from top panel "cLK install Recovery" and then hit install from bottom panel.
9- Now, if you have google drivers the cmd will guide you through the process. IF you dont have google drivers installed, cmd will stick to "<waiting for device>".
10- After the cmd has rebooted your phone, hold the "HOME" button, this will always take you to recovery (when u hold home
11- Now put your ROM and flash from recovery.
*If you lost data (which I highly doubt, simply activate then deactivate airplane mode, data will work again.
*If you want to install a different ROM, repeat the same tut but with changing the system and cache partitions size in step 6.
