My experience using KulanKendi:
- get at least 70 percent battery life. Take out SIM card and M2.
- buy a credit via paypal
- download KK SE Client, save it in D drive, and run KK SE Client
- press get login button, fill in the form to get password
- enter login and password, check account.
- click download. Pick up R1EA031 K850 CHINA MAIN CID 52.min and R1EA031 APAC ANZ.fsm. Download them, wait until transfer completed.
- go to DB3150 or A2 tab. Tick Finalisation, clear user code, reset call timer and change CDA to 1201-8437. This CDA is for Customised Indonesia which is SEUS-Friendly.
- open file MAIN and FS. They are located in FlashFiles folder in D drive, the same folder you place your KK SE Client.
- instal USB Flash Driver for K850i. You should get it automatically by running SEUS until the step when you hold C and release C.
- go back to KK SE Client. Click Flash Phone, hold C , plug in DCU-65 and wait until KK reads your phone identity, release C, and....let KK do its job. Do not interrupt the process.
At least 12 minutes afterwards it's all done. KK SE client will display 'all is done'
- unplug DCU-65
- take out battery, reinsert, turn on phone, wait until you see insert SIM Card or view demo.
- run SEUS, update to R1EA037.
- good luck.
