I own a star n3+ and I was trying to install the latest official rom from Needrom. I've done this a couple of times both using the flashtool and later using CWM. This time I tried installing from sdcard, so I deleted my data, but after cwm says "installing update" it directly says "installation aborted". Then I tried using the flashtool, but I gave me pmt changed error. Then I thought maybe the rom is not good, so I tried the 4.4 update. Both flashtool en CWM gave me the same error they did before. I tried re-installing the driver it didn't help. I tried getting back to my original rom, but cwm still keeps giving the same error. I am at a point where I don't know what to do. Now, somehow the drivers won't reinstall again so using flashtool is not possible, until I can fix that. What can I do ??
