Upgrade 10% hang problem!

[Guest ruibo]

My SPV E200 is from Orange, the original ROM version is 1.9.12.4, the bootloader is 1.05

The UK 2.7.1.1 upgrade is not OK. If I use the original VoUpgradeUt.exe, error 117 appears. So I searched Modaco and downloaded a fixed one, which can avoid 10% hang problem. The upgrade process can start normally, but the damn 10% hang problem is still exist.

Why? What can I do now?

Problem solved!

The reason is that my phone is locked. The original software is cracked so I can use other network's SIM card. I've unlocked my E200 with imei-check.co.uk, too expensive I think.

After the unlocking, the upgrade process is fast and smooth. If you want to downgrade the ROM version or change to other vendor's ROM, you should use the fixed upgrade.exe
