I have a Technosat decoder T-888. I changed the password and forgot (the password) what do I do? Please help. This is one question straight from my facebook page. This was my reply
The Technosat T-888 decoder does not have a limit on the number of times you can enter the password. So this is the solution, start from 0000 till you reach 9999. It will be tiresome but will definitely work. But I will be soon posting a mathematical solution that will be much easier and faster to follow.
The other easiest solution is to load the decoder software in a computer and connect the computer to the decoder with an RS232 cable and load the fresh software copy which will have no password. Also the default passwords of any satellite or terrestrial decoders are usually 0000. So try this first.
Now this is the proper planning and mathematical solution. It’s derived from the topic of Probability and will surely provide a solution that is much faster than entering the password from 0000 to 9999. Although you will still have to manually enter the passwords manually with your remote control. I had seen a solution in a local forum where one member suggested getting popcorn, putting your legs on the coffee table and start from 0000 to 9999. This might be comfortable and refreshing but it’s still a lot of work.
It takes an average of about 5 seconds to enter the 4 digits and press enter. At least this is my speed. If you input the password in 10 seconds it will take you (10,000 attempts multiplied by 10 sec divided by 60 sec) 16667 minutes to complete the job. This is about 28 hours going nonstop. That is a whole day plus an extra 4 hours.
This is the mathematical bit, the probability of guessing the correct password is 1/10,000. But let us split that high probability in ten . This will give us a probability of 1/1000 for every thousand count. Now the probability that the correct password is in the correct thousand group is 1/10. Are you following? Maybe this table can help. You can print it, no problem. The following tables will be best viewed from a desktop or laptop computer and not a mobile browser. Here is a Word Document version of the Two Tables below. You can easily print it from there (and fill out the remaining missing digits).How to enter lost or forgotten decoder password mathematical solution
Thousand group Probability (The probability that the password is in any of the groups below is 1/10)
|Thousand group||Most common passwords||Chances you will get it right|
|0000 – 0999||0000||1000||1/1000|
|1000 – 1999||1111||1234||1/1000|
|2000 – 2999||2222||2345||1/1000|
|3000 – 3999||3333||3456||1/1000|
|4000 – 4999||4444||4567||1/1000|
|5000 – 5999||5555||5678||1/1000|
|6000 – 6999||6666||6789||1/1000|
|7000 – 7999||7777||7890||1/1000|
|8000 – 8999||8888||1/1000|
|9000 – 9999||9999||1/1000|
The aim of breaking up the group is to increase the chances of getting it right faster than starting from 0000 to 9999 in a go.
First of all start entering the passwords you see in the table above. These are the most common weak passwords people choose. If you input a password, you can highlight it by shading it like I have shaded the 0000 box. Start from 0000, 0999, 0123 then jump to another line for example 4000, 4999, 4444, 4567. Enter the passwords in this random manner until you finish the entire table by shading it.
If unsuccessful then continue. Print the following table, notice that the values have decreased, the probability of getting it right now is1/ 9963. (This is because the passwords above are 37 in number)
|0001 – 0998||0001 – 0100||0101- 0200||0201 – 0300||0301 – 0400||0401 – 0500||0501 – 0600||0601 -0700||0701 – 0800||0801 – 0900||0901 –end|
|09011001 – 1998||1001 – 1100||1101-1200|
|2001 – 2998||2001 – 2100||2101 – 2200|
|3001 – 3998||3001 – 3100||3101 – 3200|
|4001 – 4998||4001 – 4100||4101 – 4200||4501 – 4600|
|5001 – 5998||5001 – 5100||5101 – 5200|
|6001 – 6998||6001 – 6100||6101 – 6200|
|7001 – 7998||7001 – 7100||7101 – 7200|
|8001 – 8998||8001 – 8100||8101 – 8200|
|9001 – 9998||9001 -8100||9101 – 9200||9901 – 9998|
The purpose of this table is to further divide the thousand group table into 10 segments of 100 each.
This will further reduce the probability of each single hundred group by 1/100 which is doable. Pick any box, for example 0301 – 0400 (or any other randomly) and fill the decoder with the passwords in that range. If not successful, then shade the box and pick another random box for example 8201 – 8300.
At the end of it all you will have the password without necessarily filling the nature boxes.
You can choose 3 or 4 boxes an hour, 8 boxes a weekend and within no time you will have your password.
