Hi all,
I recently purchased a second hand z1 c6903 (telstra branded), and decided I would start off by loading the iHackers custom rom on. (based off instruction in http://forum.xda-developers.com/show....php?t=2439328 and http://forum.xda-developers.com/show....php?t=2716182). Now I didn't use it a whole heap before doing this but I didn't notice any issues with the display before starting.

After the first step of downgrading to the Firmware 14.1.G.1.534 the display started going nuts. I suspected something may have gone wrong and started from scratch on another computer and re-flashed the firmware. Problem persisted but everything other than the display seemed to work so I continued rooting the phone, backing up the TA, unlocking the bootload and installing the rom. It all seemed to go fine.

Its hard to describe the issue with the display, its flickering and distorted (tried to make a vid sorry about the quality though https://youtu.be/nyD1o28ipdY)
If you can see in the video it does not do it really in some apps like the calendar and clock, others it does at first then stabilises, doesn't seem to do it at all in the drag down notification menu. Even though its difficult to see the icons, if you know where they are, they seem to respond fine like nothings wrong.

I searched everywhere but couldn't find anyone with a similar issue (May be out there but because the z1 has had such widespread issues with the touch screen thats all I could seem to find).

Was hoping someone with more experience or that has dealt with a similar issue could help in diagnosing the problem or provide a solution?

Thanks in advance

Dean
