[Desire General] kingcedz:
Steps to Flash Taiwanese or European ROM on Mainland Chinese T328W

Disclaimer: I m not claiming any credit for the tools. The tools are developed by other smart guys (some based in mainland China), and all the credit goes to them. I am merely collating and translating information here for the benefit of t328w users outside China.

And flashing ROM is a risky process as always. Use it at your own risk and have fun! 

This is a general approach, and should work with ROMs or Official RUU from different regional replease or different version. In particular, this method should install the 100% stock version of Taiwanese or European ROM to your phone, without running into the CID unmatched problem. It does not change or upgrade Radio in the process.

REQUIREMENT:

unlocked bootloader

custom recovery

STEPS:

1)	Download the pseudo flashing tool: HTC_T328w_1.56.1402.6_BackToOriginal_modified.rar

The download link: http://d-h.st/Hq2

This is a pseudo flashing tool that pretends to behave like the official flashing tool, and thus enable any unlocked phone to flash back a modified version (Slim down and rooted) of the OTA 1.56.1402.6 stock ROM. Don’t worry too much about this ROM as it is only needed as an intermediary process.

2)	Unzip the file in a convenient location (e.g. desktop), it should contain several files including a ROM.ZIP.

3)	Reboot the phone into “BOOTLOADER” by restarting (or switch on) the phone and pressing “POWER” and “VOLUME DOWN” at the same time. Then go into “FASTBOOT”.

4)	Connect the t328w to PC via USB cable. The phone should now display “FASTBOOT USB”

5)	Open the file HTC pseudo flashing tool.exe from step 2. Half the interface is in Chinese but don’t worry! It’s straightforward enough. The functions are as follow:

B – Enter Bootloader;

S – go into Flashing Mode

F – Flash the pseudo official ROM

Q – Reboot from Flashing Mode

I – developer’s information

what we need to use are S and F.

6)	Press S and ENTER, then Y and ENTER to confirm. This will bring your phone into Flashing Mode. The screen will be displaying a big HTC logo in the middle of it and nothing else.

7)	Press F and ENTER, then Y and ENTER to confirm. This will start the pseudo flashing process to flash the content of the ROM.ZIP into your phone.

8)	When its done, reboot. The phone will be flashed with the pseudo official ROM.

NOW, THE INTERESTING STEPS:

The tool is created in such a way that you can flash a great variety of different custom ROM as if they are official ROM files. All that needed to be done is change what’s inside of the ROM.ZIP file.

9)	Unzip two files from official RUU Taiwan version (PL11IMG_PRIMO_DS_ICS_40A_hTC_Asia_TW_1.59.709.3_Radio_1.05.34D.29_20.21.30.23U_release_264969_signed): BOOT_SIGNED.IMG and SYSTEM.IMG

see here for the Taiwan RUU url:

10)	Open the ROM.ZIP using WINRAR as it is, do not extract or unpack.

11)	Select the BOOT.IMG and SYSTEM.IMG, and click “Delete” on WINRAR.

12)	Click “ADD” on WINRAR, and add the two files (“BOOT_SIGNED.IMG “ and “SYSTEM.IMG”) from the official Taiwanese ROM RUU from step 9. (DO NOT RENAME THE BOOT FILES! Leave it as BOOT_SIGNED.IMG). Save it as ROM.ZIP

13)	Replace the ROM.ZIP from step 2 with the ROM.ZIP from step 12.

14)	Repeat step 3 to step 8.

Alternatively, I have created a ROM_Taiwan.ZIP that was based off step 9-12.

You can download this file and go straight to step 13.

JOB DONE!

RADIO:

This method works on all radio version. There are mainly two radios version at the moment for the Chinese mainland t328w:

the original t328w is on 1.04.34D.11_20.11.30.11U

the OTA upgraded t328w is on 1.06.34D.05_20.22.30.23U

The 1.06.34D.05_20.22.30.23U is a different radio compared with the Taiwanese or European release. But it is a great bug fixing radio and massively improves the performance of t328w. I am using it in U.K. with no signal problem at all with this radio.

This method will NOT update Radio as the phone itself is S-ON. I am not aware of S-OFF method for this phone at this stage.

To update radio, you need to restore phone to stock Chinese status, do an OTA, and repeat the steps above.

ROOT:

Depends on if you have the OTA or not, the root methods can be different. Several root method that worked on the initial stock version will not work after OTA. See other thread for root methods.
