Do you have time to try stripping it now? I have tried several images so far, and ended up moslo telling me he is unable to repartition and that I may be in trouble I'll try reflashing again but this time with erase option which takes time, but should be better for the phone.

Which image do you recommend flashing, anyway?

It depends what you want to do? Do you want to update to using the normal (6 bootable-OS version) of ubiboot from your current sailfish-only ubiboot?

In that case, you need not flash the ubiboot kernel, since the kernel is same on both versions. Instead, you need to replace your ubiboot-02.035_SF_v1.cpio with the CPIO file for normal ubiboot, and also edit your ubiboot.conf accordingly.

What ? ..how to edit the ubiboot.conf .. And what to edit in it can't I just replace it with anothet one !

I fon't understand in these stuff

How to uninstall/remove ubiboot .. ?? And re-install it ... is it easier ??

If flashing with "--no-preserve" does not cure it, then it is very problematic
