MT6235 (M008) IMEI problem - 15th figure

Hello infinity, first I have to say thanks for this great box, it helps a lot :) But to the problem:

What is the deal about that last (15th) figure of IMEI number?

Problem is that I have formated ffs (safe method) on few MT6235 WiFi M008 phones, so I have to write back two original IMEI numbers.
But when I fill out those 14 figures in service tab (CM v3.10 btw), the last figure fills out automatically, but does not match the number on the phone's sticker (and "inside" phone, I did "read general information" before formatting).

When I try to write both IMEI with mode-1, it works, but that 15th figure is written automatically, even if I rewrite it.

Example:

Code:

Original IMEI #1: ...12401

Original IMEI #2: ...18601
 
 Auto-filled IMEI #1 in CM: ...12403

Auto-filled IMEI #2 in CM: ...18608
 

formating ffs..

writing IMEI #1 and #2 (filled ...12401 and ...18601)..
 

result:
 phone IMEI #1: ...12403

phone IMEI #2: ...18608

But even more, when I write one of IMEIs with mode-2, it automatically fills out the other IMEI somehow:

Code:



write IMEI #1 ...12401
 
 result:
 phone IMEI #1: ...12401
  phone IMEI #2: ...20265
 
 

Or even:
 

write IMEI #2 ...18601
 
 result:
 phone IMEI #1: ...18601
  phone IMEI #2: ...18608

I would not like to leave those phones with another IMEIs than original ones. Please, any solution?

P.S.: mode-3: "method is not supported yet"

MISTAKE: does not matter #2 IMEI in that example, i took another phone in that part..

So to set this right, the IMEI #1 can be written OK with mode-2, but when I try to write second IMEI with mode-2, it results as I have already written:

Code:

write IMEI #2: ...18601
 

result:

phone IMEI #1: ...18601

phone IMEI #2: ...18608

And if I write any IMEI with mode-1, it always results with wrong 15th figure. Sorry for making mess a bit..

hello!

situation is following. Last digit is not random, just any which you wish.
it must be calculated by spcial algo called "Luhn algo"
here you can find information about it:
Luhn algorithm - Wikipedia, the free encyclopedia
this is why our software calculate it itself

last IMEI digit in your examples is not correct, probably chinese guys do not pay much attention to this
more about correct IMEI structure you can read here:
International Mobile Equipment Identity - Wikipedia, the free encyclopedia

I thought it is something like that, thanks for explanation. China guys obviously don't care about it, but I do and now I'm confused of how to solve this..

hello!

i would advice to leave last digit as our program set it.
some network may refuse phone to work if last digit is incorrect
