- First download the pseudo flashing tool: HTC_T328w_1.56.1402.6_BackToOriginal_modified.rar. 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.
- Once downloaded unzip the file, it should contain several files including a ROM.ZIP.
- Next reboot the phone into the “BOOTLOADER” by restarting (or switch on) the phone and pressing “POWER” and “VOLUME DOWN” at the same time. Then go into “FASTBOOT”.
- Then connect the T328W to PC via USB cable. The phone should now display “FASTBOOT USB”.
- 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
- In all these, we will use only S and F.
- 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.
- 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.
- When it is done, reboot. The phone will be flashed with the pseudo official ROM.
- Actually, 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.
- Unzip two files from official RUU Taiwan version (PL11IMG_PRIMO_DS_ICS_40A_hTC_Asia_TW_1.59.709.3_R adio_1.05.34D.29_126.96.36.199U_release_264969_signe d): BOOT_SIGNED.IMG and SYSTEM.IMG.
- Open the ROM zip using WINRAR as it is, do not extract or unpack.
- Select the Boot.img and System.img and click “Delete” on Winrar.
- 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
- Replace the ROM.ZIP from step 2 with the ROM.ZIP from step 12.
- Repeat Step 3 to step 8. If you want to install Taiwan ROM then download it from here. After you downloaded this go to step 13.
