Hello,
My phone is Prestigio PAP5450Duo

I need your help. I used ROM Toolbox to try to change battery icon. On reboot there was a message "System UIDs inconsistent" and no Wallpaper or Statusbar. I don't have SystemUI.apk backup but I tried to restore the backup from ROM Toolbox, it didn't work. And to prove I am a true idiot I accidentally deleted the SystemUI.apk from /system/app. :crying:
Would finding another 5450 phone and copying SystemUI.apk work?

Thanks in advance!
