But if I send for warranty, I have no phone to use..such a new and expensive phone..very sakit hati if have to send in service
If send in, how long it take to repair?
Normally what kind of situation they will replace a new 1?

btw, what is your radio version? perhaps upgrade to latest radio rom will increase the reception.

ROM version : 1.18.707.3 (23358) WWE
Radio version : 1.09.25.14

Where to check for latest radio version? How can i upgrade?
confusing flash ROM and radio

Latest radio for HD : 1.17.25.0.9 = refer to http://forum.xda-developers.com/showthread.php?t=466274 . The radio is for your call/data reception. Installing new radio WILL NOT erase your data But you still need to HSPL your device in order to do it

Flash ROM will change your whole unit operating system - all your data and installed 3rd party programs will be erased

I suggest you test your sim with another basic phone first when you detect call/sms issues to discount is hardware problem. IF you have bought from SIS , normally within 7 days you get unit back. If AP possibly up to 2 weeks or more. Replacement FOC that is exchange normally within 7 days purchase

any other chinese input other than A4? Coz A4 will screw up the message recipient number (the auto completion).

Ok..by the way, upgrade radio will void the warranty? any disadvantage?
And is it necessary to flash ROM if we flash radio? if only flash radio, won't have any problem right?
Why we need to flash cooked ROM?

Any change in radio or ROM will void the warranty unless it is an official updates from HTC website.

You can flash only the Radio without flashing the ROM
Cooked ROM are usually faster than shipped ROM and also remove some bugs. Some have better UI.

Oh..ok..

Ic..but it will void the warranty..the guy from pda shop advice me don't flash ROM because my phone still under warranty and still new

anyway, any keyboard input recommend? I like the default keyboard, but it's too small..Full QWERTY got some bug with it..

You can always flash back the original ROM before sending it back for warranty claim. Use HSPL method and it will be untraceable..

As what Superman7 said "Flash Radio or ROM will void warranty". If you flashed radio or cook ROM, you can always flash it back to the stock version if you want to claim warranty. Cook ROM is always better than stock ROM. Stick to WM6.1 ROM.

TouchPal is a good Soft Input Panel but it is a $$ware.

I know..but I don't know how to HSPL..I'm reading xda forum quite few times..but still can't get it..
There is no way I will flash wrong?? I just scare that HD can't on..
1 more thing, When I call/wifi/GPS, the bottom part of the back is hot, is this normal?

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"

i like the quote " rom freak" "rom addict"

Wow! You took such effort and time to clarify this issue. Great work.

TIME is what a retiree old man like me have loh !

Happy Posting!

nice explanation.. probably no one would ever ask what is the advantages of cooked ROM again..

can i know if i want to change my hardware,roughly nid howmuch $$??
