Going to stock Dual Sim Rom from a carrier

Hi folks, greetz from PT,

I know another thread with this is a bit pointless but the other thread is a mess and could use some cleaning up.

Anyway, breaking down,

Going from b133 VDF to b052 Euro unbranded with unlocked bootloader only:

Downloaded the full "update" to 052
Had the update.app in the dload folder and flashed it
rebooted by itself and kept all settings (odd), let it sit and update some apps
Balong "bug" - Flashed step2 with vendor cleared as sugested in a weird confusing way here on XDA
Flashed step2 - it rebooted again but made a factory reset by itself, the way I was expecting on the full
package (odd)... (do not sign in to google)

Downloaded B136 from OTA and flashed the update (354 Mb)

Did a small update and indexing and nothing else.

The question is this...

WIFI - It goes like stink
Bluetooth - Works fine
double writing on text - Never saw it, works great...
Double tap to wake - Works since 052

I could post links to files, not sure if it's allowed anymore, this comunity seems to be winding down, mostly due to bickering... that's sad :(

Don't agree with some rules but ... oh well.

Anyone had any problems with the updates lately ? I found it odd they worked all on first try with so many bugs reported... ?
