How To: Load a Custom ROM on the T-Mobile G2 / HTC Vision

I. Before You Begin

1. This method is for flashing a custom recovery image and custom ROM.

2. You MUST have done our How To Temp Root and the How To Perm Root / S-OFF procedures for the G2 BEFORE coming to this procedure.

II. Flash a Custom Recovery Image

1. Once you have done the above to procedures, open the Market on your phone and search for ROM Manager (Free).

2. Install it.

3. Open the ROM Manager app and click Menu, then Settings and turn ON Delete Recovery.

4. Click Back and then select Flash Recovery.

5. Choose your phone model and then let it flash the recovery.

6. Click Reboot Recovery and you should be put into the custom recovery image screen. If so, you are all set.

*If you get a phone with a red ! symbol when you reboot into recovery that means it didn’t stick. So just take out the battery and put it back in then turn the phone on and repeat steps 3-6 over and over until you get a black screen with green writing on it instead of the ! screen.

III. Flash a Custom ROM

1. Head to our ROMs section and choose your specific phone. Then click on one of the ROMs and select which one you want. Download it and save it to your computer.

2. Once it is saved, plug in your phone via USB cable and mount the SD card so we can save files to the sd card.

3. Copy the ROM’s .zip file over to the root of the sd card (NOT in any folders on the sd card, just on the root of the card) (do NOT extract it, leave it as a .zip).

4. In the custom recovery screen, select Nandroid then Backup and backup your current ROM.

5. Then select Wipe Data.

6. Then select Apply .zip from sd card and choose the ROM you downloaded earlier.

7. Once it is done flashing, click reboot system. Once it reboots, you are all set. Enjoy!

  • Wendy

    i tried to flash clockworkmod recovery> and it flashed it in like two seconds. then when it tries to reboot i get nothing but a white htc screen. I left it on and it doesn’t do anything unless i take out the battery. what do i do to make this right? anyone? and please hurry!

    • http://TheUnlockr.com TheUnlockr

      Make sure you did the How To Temp Root procedure and then the How To Perm Root procedure. Then come to this one. If you have an issue getting the recovery to stick just read the * section under Section II.

    My phone doesnt have android market or any stock apps anymore, what have i possibly done wrong? I dont have gmail and i reseted my phone and still dont have anything. some one help

    • http://TheUnlockr.com David Cogen

      You probably load a Cyanogen ROM. Simply go to where you downloaded the ROM and look for a “Google Apps” or “Gapps” .zip file, you need to flash that separately in recovery after flashing the ROM. If that doesn’t work, just flash a different ROM.
