try this.
It works 100% all the time..
actually I just flash Xannytech ROM Grid Evo Turbo 1.6 yesterday and it's working fine.

Bottom part of the back is hot when you're on call or wifi or GPS or basically any process hogging application. It is normal.

We flash cooked rom because we like to "play" with our phones and maximise its potential. Microsoft firmware is "safe" and developed for the masses to ensure no major complaints that it is unuseable or hanging issues.

It is analogous to why people esp guys spend Rm 20000 - RM 50000 just to upgrade their car sound system or similar amount to modified their car's engine/transmission or bodykit. Sometimes these costs is similar to car value or even exceed the car's value. For example I have a very old Cefiro ( bought it new and use it 19 years  )  - one  guy bought it from me and spend 3 times the car value to modify it just for drifting purposes. A more common comparison is most people will spend a fortune renovating their houses whose costs usually is 50 % to 100 % the house value
In all these cases why do people do it ?? :  to be different ? to have a better enjoyment of their asset ? to maximise the potential and value of their asset ? or too much money dunno where to spend on ?

Off digressing, we flash cooked roms because we want to maximise and "push" our units to perform beyond what Microsoft intended;. Some of the advantages of cooked roms are:

1. Better memory utilization : MS roms memory built up very fast and if you browse a lot and multitasking,  you find out of memory issues fast.  Cooked roms nowadays by default increased memory by 10-20 % ( depending on which cook )

2. MS roms builtin a lot of stuffs which majority don't used; so in most cooked roms these are removed as you cannot uninstalled it in the original unit

3. Some cooks offered CLEAN or LEAN rom which left a basic functioning unit  ( my favourite) : I then install in what I like and I save at least up to 20MB of storage memory from MS rom

4. Some cooks build into their roms a wide range of useful utilities for those who are too "lazy" to find/research/or install such utilities

5. Some guys change their roms because they preferred the new icons setup and icons layout ( these if you put in some effort you can easily do yourself ). For example I like CellPro lite roms but I hate his color scheme /icons - so after flashing I change all the icons/folders/layout according to my own taste. I like his rom because it is really lean compared to others and offer fantastic low memory utilizations

6. Microsoft is continually upgrading their builds and all these cooks capitalize on it and built it in theoir roms ; for example the HD the manila build has progresed to 21885 and at WM 6.5.3 while the original HD firmware till now has remain unchange.

Now you can run WM6.5 ( so many versions available, at last count at least 15 )  on the HD.

You can also now run Manila 2.5 with some bugs on the HD ( which was developed for the HD2 ) or run another version of WM6.5 ( build 280@@@ onwards ) where is more finger friendly and obvious start menu relocated to bottom. The variety of cooked roms is fascinating

So guys who do not like to see the same "dashboard when driving" every day change their "dashboard" often . In our case of roms,  this do not incurred any cost just time to install/test/evaluate - so much so if you look thro the XDA forums you find many regulars ( including me) who just cannot stay long with just the same rom and continually changing to find their "ultimate solution "  - we are what every one calls "Rom freaks or rom addicts"

So as long as the cooked ROM is for Touch HD, there is impossible got problem??
Wow..you writing essay? haha..anyway, thanks for your long explanation..really appreciate..

1 question..what is the difference between USPL and HSPL? which 1 able to flash back original ROM? which 1 more safety?

It is better for you to use a USPL. It is easier to use and less problem.

Then after that how can I restore back to original ROM?

Just repeat what you have done but with the Stock ROM. Stock ROM is available here.

Ok..thanks..will do it when i free 
So I must use Windows XP to do flashing? Currently I'm using Windows 7..

Use WIN XP to avoid any hanging issues and subsequent "bricking" your phone. Don't even consider Win 7 and Vista : there are already so many cases of failures.

new hd user here.currently on the journey of searching the fastest and stable rom! any suggestion?

i tried dutty's holy grail, miri v31 premuim and currently on xgrid leo 2.4b!

wow..can I use virtual machine to do it?? 

Avoid using VM to flash, unless you really have to try.
