Cụ Meta đây biết làm vì đã làm rồi.
Trước tiên bạn phải downgrade ROM xuống ở phiên bản cơ sở (gọi là button ROM), unlock CID rồi upgrade lên Windows Mobile 5. Khi WM 5 đã chạy, lúc này nó đã giải khóa (unlocked), bạn có thể upgrade lên WM 6.
Well after getting my Wizard a few months ago I looked into unlocking it. The tutorials I found weren't the best because of how many threads they linked to you too which contained more reading to find a simple link. Well I've hosted all the apps you'll need to get your G3 Wizard unlocked with a step by step instructions.
1.Find out if you have a unlockable Wizard meaning G3, if you have a G4 this isn't the thread for you.
you'll see these numbers when you turn on your device
G3 DEVICE: IPL/SPL: 1.XX or 2.XX or 2.XX.00X (only two zeros)
G4 DEVICE: IPL/SPL: 2.XX.000X(three zeros)
2. Okay now your ready to load the Button Rom which you can download here, just connect your phone and open up this exe and fallow the steps the exe gives you.
3. Once your phone turns back on after loading that rom, you'll see a Beer glass as the first picture confirming you've properly got the Button Rom, Once your phones on DO NOT sync your phone just cancel the Active Sync set up.
4. Now download this Lokiwiz.rar, Unrar it and send the cab to your device install it and restart it. Again DO NOT sync your device with Active sync.
5. Now you'll have a Bat in the folder you unrared. Open that you'll see
C. CID Unlock(super CID)
6. if you want to unlock your phone to all carriers hit "u" for sim unlock let it restart and if you want to unlock your CID hit "c" let your phone restart and remember DO NOT SYNC with Active Sync between unlocks
7. Now your Wizards unlocked, Heres the T-Mobile Rom to upgrade your IPL/SPL, Download Here. Enjoy your unlocked HTC Wizard and go flash some new WM6 Roms.
