no error since you haven't change flashchip, and writting only gdfs. Normal behaviour

Same problem here trying to repair IMEI, what can we do?

OTP: LOCKED:1 One time programmable

352208012382654 is a correct imei for k790a

to change it
1 check your country laws
2 use the gdfs solution (unlock +imei change)

* select k610
* mark only SIGN MODE ( 1.01 version already gdfs repair free)
* press RECOVERY
* connect phone with usb or com port
* you get brown 49 K610 after successful RECOVERY
* switch to empty board tab
* select K610
* add K610_GDFS_SSW.ssw
* add DB2020EROM_CNV_RED52_BROWN_CID49_DB2020.ssw
* click flash
* now u get red 52 K610
* flash with red 52 firmware check on settings signed mode "customize phone after flash"
* DONE.http://forum.gsmhosting.com/ubb/smile.gifhttp://forum.gsmhosting.com/ubb/smile.gif
