nothin
 

dont have any info about it ?

Hi,
Is it was any errors during unlock process ?

hi
 

no , at all the phone became dead after remove the solder point of pcb of n1 ball

its not the first time i have just unlocked this phone by removing n1 solder point of pcb i always remove this track , but this time the pcb are completely diferent and the old n1 point posision its not the same i think cpu is diferent in this type of pcb`s

and... just and idea

the leds of infinity box blink rx & tx as the old c139 , in my experience the old tp phones by cuting track when i try to read with infinity box , the box boot the phone as usual, i can see rx & tx leds blinking but

in boot erased phones when i try to read the phone just one led is blinking.

in the case of this phone i think is not boot erased because when i try to read with inifity box i can see the 2 led blinking just like the old rev of pcb with non boot ereased

sorry if my explanation its not good because really i dont know nothing about programming but i see this diferences betwen

thanks for response
