I own a Huawei Ascend Y300 which I rooted, unlocked bootloader and flashed custom rom with cwm.
I wanted to go to complete stock (because my varranty is void if rooted etc.) so I found a guide on modaco that required twrp instead of cwm to get to stock. Then I found a different guide that said to do " su dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4 " in terminal emulator. Now this is where the problem begins. I'm not sure if I clicked restart or shutdown after writing that code in terminal, the phone wouldn't turn on for like 5 minutes so I pulled out the battery and now I cant boot into anything. I can't get into phone, recovery, fastboot or anything.
Have I bricked my phone, please help?
