DISCLAIMER

I will not take any responsibility for any damages caused directly or indirectly from using the software-package or the instructions. Read the instructions thoroughly and proceed carefully!

Hi,
some people have a problem with checksum error while upgrading bootloader.
After this error ,you can flash wp7rom but windows will not start.
And you can go back to wm6.5
I had this problem too. Problem was solved by flashing all files: ENPRG8650.hex, NPRG8650.hex, amss.mbn, apps.mbn, appsboot.mbn, dbl.mbn, dsp1.mbn, fsbl.mbn, osbl.mbn, partition.mbn and chosen flash.bin.

In your tutorial there are only 3 files flash.bin, NPRG8650.hex, partition.mbn.
All needed files can be downloaded here:

You could add this exception in your tutorial.

You can also add warning that sd card will be formated and encrypted. This is important information for noobies like me, because you lose all data from card and there is a problem to use this card outside the phone and wp7.
And there is no easy way to remove encryption. For example you can format such a card in nokia with symbian:

Another useful information is how to Use Your Windows Phone 7 Device as a Portable USB Drive. So you could also add link to this small tutorial:

At last but not least thanks to all people that enabled wp7 for tg01

I will complain it about 5th time...

You cut USB cable, any type, unisolate red and black wires and put red to + and black to - in battery, wait about a minute holding it like this and check, if fails, repeat this cycle until you get battery working.
You can also check battery voltage with voltagemeter, 4.20 is 100%, 3.7 is about 60% and 3.0 is critical state assuming you damaged your cells.
Any overcharging or undercharging (more than 4.20 or less than 3.0) would make your battery funking explode...
