Huawei D2 bricked
Hello everybody! Hope I've chosen right forum for this thread.
I've got problem with Huawei Ascend D2 - something wrong has happend with stock firmware (when the phone starts, the logo screen freezes), now I can load it only in recovery mode. The recovery is stock. I've downloaded stock firmware (update.app), so now I have to put it at sdcard/dload/ folder and then choose it in recovery mode. The phone is availble in ADB, I can see it and connect to it. But when I want to push update.app to this folder I got "Permission denied". I understand that I have to root the phone, but I don't know how to do it in ADB. Every solution that I've found required working firmware.
