[Q] Can't update from HC to ICS

[mikajo]

Hi guys!

I have a problem updating my Sony Tablet S from (rooted) HC to ICS. I always get the message Could update, errorcode seven. Now I have read a lot and I think it is because I have the wrong region. I have the german tablet with 3G.
I remember, that I along time ago changed to (I think) US (I don't remember why I did this). Now I wanted to changed back, so I changed to German region with 3g. However, Update failed. So I read, that I can press number 0, so I change back to original region. However, it failed again.
So now: I don't know what I can do... Do you have an idea for me?
My model is: SGPT114DE/S

Hoping, someone can help me

Thank you!!!

Have you tried factory reset?

Have you tried factory reset?

Thanks for your respond! I would do that, but I don't know how to backup all my apps and reinstall them when I am on ICS. I could use Titanium Backup, but if I don't get ICS rooted, I couldn't install the backup (I think...). Am I correct? Do you maybe have another idea?

Thank you very much!

You can 100% root ics! New method works on any ics todate
