I have tried flashing a couple of official huawei ROMs (b175 & b182) using the dload folder update.app method but without success. When the volume+/volume- button is pressed with power button the phone enters the huawei forced update function and shows a simple pink progress bar (no text) which stops after around 1/3rd progress.
The phone also refuses to boot into stock recovery via the volume+ & power button.
Maybe it needs the bootloader unlock key from huawei before I can move further? I have tried requesting it by email from huawei, but they directed me to ask for it via their bootloader unlock request webpage. That's fine but obviously I can't get the 8 digit product ID from the phone which is required on their webpage. It won't let you submit a request without this 8 digit product ID. The ID must be unique to each phone because the one from my working Y300 isn't accepted by the page.
Any ideas anyone?
