Sorry if someone have posted something about it but I havent found it on the forum.
Someone might ask "what is the point of backing up when all is patched and working?". This is exactly the point - if am satisfied with the results with what I have done - I would like to preserve it so I can restore this succesfull configuration for future if later decide to patch something more anf f*ck it up. :)

In last week I have killed my W810 4 times patching about 20 to 25 vkp files. Discarding some of them now have about 12 to 15 vkp working on my phone and am satisfied (more or less). :)
It appears that some patches are conflicting with others and the result is phone that will not power up. Flashing initial MAIN and FS R4EA031 I have managed to "revive" it 4 times but it is far better if it is possible to make a new MAIN an FS (with working patches included) and have less things to patch when I kill it next time :)
