Last night I updated my Vodafone Huawei Ascend G300 8815 from (I think) B892 through B895 to (I think) B936 over the air. The update to ICS seemed successful. It worked OK for a few hours while I
- restored my backup made using the Huawei app,
- rooted the phone & unlocked the bootloader
- uninstalled the Vodafone crapware using ROM Toolbox Lite
- fixed the language bug, etc.
Now when I turn it on, after a couple of seconds of the Huawei logo I get a black screen with a yellow triangle with an exclamation mark. Below this is "Image Signature Verify Fail!" in red, then the following in white:
"Your appboot image may have an incorrect signature.
Please update your image to a signature official one.
You can remove battery for power down."
No change after several battery pulls, and removing the SD card.
I can get to the pink screen using vol+ vol- and powering on but although I have installed the drivers no partitions appear in Windows.
I am not running CWM, Titanium or anything like that.
I have no DLOAD folder on the SD card as one of the post-update suggestions was to delete it as its presence supposedly interfered with mounting the SD card properly, so I can't reflash from the pink screen which I've seen suggested elsewhere.
What do I do next? I'd be quite happy to forego the ICS update just to get my phone working again!
Another thing, does anyone know if the phone will charge the battery while the pink screen is showing? It was down to 49% before this happened and I'd hate to flatten the battery while I muck around with it.
Thanks in advance for any help.
