Lumia 620 touch screen probleme when updating

Hi
i have a Lumia 620, once i have changed the touch screen (old one is crashed)
it was working fine, but when i try to update, the update finished fine no problems
except the Touch screen, it stops working :'(
i tried all firmwares available (on mrcrab website) no one works with my touch screen
i think that because Driver files are missing
except one with the product code 059P927

but it has no updates at all (no Amber, no Black, no Cyan)
--------
can anyone help me to get the updates for my phone ?
or is there a way to edit flash file image (.ffu)
and copy the necessary driver files ?

Re: Lumia 620 touch screen probleme when updating

Seems to be a common problem when updating to Cyan with a replacement touchscreen. I have a similar problem with my L820 but my screen works a bit. Was your touchscreen working on Lumia Black? I haven''t had the time yet but you could download nokia care suite and navifirm+. Make a donation to navifirm and get the Black or Amber firmware

Thank you brother for your answer

I tried to flash it many times with navifirm and nokia care center same problem when using newer firmware

i hope that there is a way to edit flash files to add the missing driver files
