Exactly the same problem here. Bricked my Y300-0100 by using v10 of this tool. Only working thing is the Vol +- method to flash an update.app, but they all fail at ~1/4th. Hope a solution will be found! For other Y300-0100 users, don't use v10 of this tool!!! I've seen multiple ppl brick their device.
Updated to the latest version few days ago. I've experienced two issues since: - My phone won't unlock anymore. The touchscreen is not responive on the lockscreen. Hardwarebuttons do respond though. Solved after wiping cache yesterday, but issue popped up again today. - Last night 'android operating system' consumed 488MB, emptying my entire account (I pay per MB). Any suggestions fixing either of these problems? Thanks!
