[Xperia Arc Q&A, Help & Troubleshooting] Wirrus:
I cannot use flashtools in my phone, i installed drivers several times and i can use smoothly fastboot but i cant flash any files to my phone

There is no problem to getting into flash mode, sometimes when i trying to flash it quits from flash mode and starting to charging but it happens rarely

I am using nokia's data cable not the original se's cable

I cant find any solutions in forums also
