There are
millions of China Mobile users (Sansung, Nokla, Gionee, Gnine etc..), but most
common users don’t know what are the codes including default security code.
Most people know 1235 is the default Security Code for Nokia mobiles, similarly
China Mobile has the codes. Since most of the manuals come with the Mobile box
is written in Chinese or Asian language, we can’t understand what are the basic
things that we need to know, and so we just follow operating the handsets in
the same way we operate other handets (eg. Nokia, Motorola, Samsung, etc.). I
would just like to present some important China Mobile Codes so that we may not
be facing trouble while using these handsets.The default Security Code is 1122,
this works with most of the handsets but there are some more, here they are
3344, 1234, 5678. All these are default security codes.Now let me just brief: *#110*01# :
Engineer mode *#987# : Factory

-Device-Set UART-PS Config-UART1/115200:Enable COM port *#987*99# :

: Unlock Note “code” = Your security code These codes are not for a particular model, but as
general, some will work with yours and some of them will not, and vise versa.If
anyone knows more codes, please add as comment so that we can help each other
in a better way. Good luck to you all.
I'd recommend reflashing your K810i via the Wotan website. You can browse & find a Dutch language version. It's all explained online. Cost is 1.99 Euro for five flashes.
This service doesn't unlock your phone (it's unlocked anyway) but it will remove carrier branding on either a locked or unlocked handset. Sony Ericsson K810 Firmware Flashing
Yes, it's fine. Even though you have to select which phone you have, it will detect the current software version you have before updating and advise you whether there is an update available. This holds true for all SE phones with the "i" suffix.
