I have tried so many methods that I fell so confused and thinking this the end of my phone.
The stock ruu.exe method gives me error 155.
flashing ruu.zip gives me error:
(bootloader) Read zipped android_info fail
FAILED (status read failed (Too many links))
finished. total time: 149.356s.

And i dont know how to select the correct Firmware, kernel ETC.. Please help
