Default [Q] Problem to Update to Android 4.4.4 (14.4.A.0.108) on rooted phone

Hi,

PC companion doesn't want to update my rooted Z1 compact.
After PC software preparation and after I accept the "information" my connected phone powers off (step which I think is normal) and then I get the following message:

"The phone contains modified software that cannot be updated"
"Sony update Engine failure (error 2003)"

Can someone help ?

Bought my phone in March, works well, runs 4.4.2 and was rooted.

Tks in advance
Eric

Default ftf?

Hi Lasantha,

Tks for your reply.
It looks quite easy but could you please be more explicit. This would help greatly. I'm a idealist rooted (I think we should be able to do what we want with our phone) not I don't have a lot of tweaking knowledge.

1 flash ftf using flash tool (what is ftf ? and which flash tool would you use?)
2 then root again (was thinking to root again with towelroot
3 remember to untick data wipe if you want to keep data (where should I untick this ?)

Many tks in advance

Just use the SEUS update, via computer. Not PC Companion, but SEUS. It worked for me...
