Yeah :),and I will not have problems changing the current rom you recommend me?
As you are apparently under Product Code Engineering, I do not know if it will work...
If you try it, so to "recap":
- If you want for your country, use 059T9S1 RM-892 VAR LTA CL ENTEL PCS SL BLACK
- If you want a naked/unbranded rom, use 059T5T0 RM-892 VAR LTA BR CV BLACK

And use http://xdaforums.com/showthread.php?t=2515453 tutorial.

Thanks a lot,but honestly, do you think it works? You've seen other cases?
If the material is no different and that there is no particular constraint, I see no problem. To tell you, if I have a nokia engineering, I would try the flash. But me it's me. You it is you. So do as you feel.

Such as your nokia is a engineering/development phone (even the firmware is not available on the Nokia servers), you can not flash.
See http://forum.gsmhosting.com/vbb/f609/how-connect-lumia-820-under-winxp-1745996/

This is developement phone. You cannot flash this with regular non development firmware.
Return to Customer.
