Member: 238127 Status: Offline Sonork: 100.1574867 Thanks Meter: 3,528 | how to calculate nck for zte phones such as x760. This is based on the whole theory by elcapitel, i have only realized of one little step but most of the work was done by elcapitel, we must thank him for this wonderful research. Let's begin explaining how it is done, but if you have read this whole thread you should know most of what i am going to explain here. let's take the following imei (only important 12 digits are used) 000002 243814 our first step will be to sum all digits: 0+0+0+0+0+2+2+4+3+8+1+4=24 then we will calculate a line which is the result of our sum 24 by each digit of imei. 0x24=0 0x24=0 0x24=0 0x24=0 0x24=0 2x24=48 2x24=48 4x24=96 3x24=72 8x24=192 1x24=24 4x24=48 this way we have: 000008 862246 now the second step is based on this chart: Code: 1 ............... 8 2 ............... 6 3 ............... 4 4 ............... 2 5 ............... 0 6 ............... 8 7 ............... 6 8 ............... 4 9 ............... 2 0 ............... 0 000002 243814 and now based on the chart we have two make another line based on the digits in the chart which corresponds to the digits on the imei, and inverse the order. it sounds a little confusing but i know you will understand. so for our imei 000002 243814 we have: 284426 600000 pay attention to halves colors so you can understand it better. you can see, for instance, that for the number 2 you get number 6 and so on. now third step is to use the following line: 688950 000000 which is the magic line you get when you calculate the nck with all 0 in imei. if we put all three lines in order we get: 000008 862246 284426 600000 688950 000000 we can easily sum digit by digit, and in this case we get this: 862374 462246 which for our surprise will be the nck for the given imei. so for imei 000002 243814 we get nck 862374 462246 i have tried we a couple of examples and the result is the same, don't have delphi here with me now but sure someone can code this algo and make more tests to see if everything is correct. this is another test i did: 000012 243814 --> imei sum: 1+2+2+4+3+8+1+4=25 000050 005050 --> firs line 284426 680000 --> second line 688950 000000 --> third line 862326 685050 --> nck once again thanks for all interested and specially to elcapitel for his hours dedicated to understand this. luck; |

Member: 238127 Status: Offline Sonork: 100.1574867 Thanks Meter: 3,528 | in the second step i just explained things harder i realized now it is simpler just follow the chart digit by digit until you get full line, then reverse the whole line to sum it with the others two and thats it, luck ps: and please this is all for educational purposes only i know that many like myself included are more than happy to know how a code is calculated but we must remember we eat from this business |

Member: 166270 Status: Offline Sonork: 100.1579747 Thanks Meter: 12,673 | yeah my great friend @y3kt. This is for @ALL and especially for those people who thought I could not find the algorithm. Here an example that I have discovered the precise algorithm for calculating the NCK in zte as the x760. It is also a proof that if you show real interest the you can achieve anything. :-p Now, the program will not be posted at least by me at any time for free. I will not kill the market. It was never my intention. br elcapitel Quote:
