RCD310 Decoding tutorial..

[mesterel87]

Is there any RCD310 tutorial on how to get the code from MCU+EEPROM dumps?
All I found is the first two digits code.
I read the EEPROM and the MCU with a CH341A programmer ($3 only china manufactured)
I can upload some schematic if needed is a very sample procedure.
I need to know how do I calculate the full 4 digit code from the dumps.

Regards

Use the search button, there are many threads explaining how to read your NEC dump,
once you have your files post them here and someone will decode them for you...

I already read the dumps and got the code I asked how you can get the last two digits from the NEC dump..

This information is not for sharing, but many here will post your code if you post dumps...

I see. No problem if the info is not for share
The code for the dumps is: 0272

Thanks anyway.

There are 100's of examples like this here, it still won't help as the solution is very encrypted and took years to solve...
which is why people here won't just give it away for free... you have to earn it not expect it ;)

I don't want to earn money I just want to understand how the last two digits can be done by reading the NEC MCU. If I want to earn I can buy a MARTECH and the tool can do this job in minutes.
There is nothing to hide unlocking that RCD 310 actually this radio is about 30$ second hand. How much do you think you can earn by unlocking RCD's radio :)

If you just want to leach off others here then you'll get nothing,
your lack of respect to those who spend years solving these is amazing.
They are NOT just going to tell you just because you demand it,
it's not about cost, it's about knowledge and time spent solving problems.
We see people like you every day, not willing to do any work or make any
effort to solve codes, then expect everyone just to tell them everything
just because you demand it...

I don't disrespect people's on here just telling that if you have the two digits of the code by resolve the russian algorithm you can get the last two in 10 mins by entering 00 to 99 combination without reading the TMS I don't see this information too precious everyone can unlock this radio reading the EEPROM only. Just telling the time is same even if you read the EEPROM and trying the combination's for the last two digit's or reading the TMS post the dumps on the forum and wait for someone to respond with the full code. Tell me if I'm wrong.

You'll have to post and wait like everyone else,
and what you call the "Russian" algo has been known by many long before the Russians ;)

I don't need to post and wait. I can get the code myself! I just described how can be collected the full code just asking for myself what is the algo for the last two digits on the TMS it's all about my and others knowledge we don't earn anything if someone give that info to public I told you already it takes 10 min to try 00 - 99 combination. Is more fastest trying the combination as reading the MCU!

If you can get the code yourself you do not need anything else... Solved!

[mesterel87]

You are right! Just telling others there is no need to read the TMS after finding the first two digits it takes minutes to find the last two manually no need thanks giving to you and wait for the full code calculated by your magic mind.
By the way how did you found the algo? Searching on google or asking a friend :)

First of all the RCD310 does not have a TMS, it has an NEC, not the same...
and secondly it took me over 3 years to solve it by my own, noone here told me.
Others have solved it in much quicker time and deserve praise for doing it.
Suggesting I either Googled it or asked a friend is insulting...
Your attitude needs adjusting, terms like "Magic Mind" will not help you here!

Knowledge is more expensive or invaluable. You don't want to think for yourself so decode these radio in the way you choose

[mesterel87]

You are right there is a NEC not a TMS is not a same chip but the difference between that chips are not too big. Three years? Really? You spent three years to find the difference between two bin files and calculating two digits even you know the first two digits of four and have the possibility entering 100 combinations to fit the last two of four? I think this is a crazy job and a long time spent without any satisfaction you just looking for thanks packets on the forum thinking all people over there are retarded or something like that and you are a "Magic minded" or something like that. Anyway I understand the situation and your frustration too so this topic aren't depending your reply. Just let the balls how them has rolled.

Have a great day/night.

You are right I've spent a day reading the MCU i'm not an electronic expert after that I've looked at the two bin's extracted from the chips looking for the mathematics difference I'm not a smart guy like everyone else on this forum that's why I asked for a professional response on there. As I see there is no chance finding a response for my question on this forum so I'm not looking to find the answer for my question on there anymore.
Just respect your decision, telling you and everyone on there have a great day.

It seems you are only angry because we will NOT tell you... it is obvious now...

The way to crack this algo is to first learn the basic Blaupunkt RCD algo which is very easy and has been in use since 1997. Learn it fully and understand why 8 = 9 and vice versa, and how the counter values work. The same algo is also used in Opel CD30 radios but with a fixed offset.

Once the old algo is fully understood, apply the same thinking to this RCD*10 algo and you will make progress.

As Shooting and Raimax have mentioned, there are alot of lads on here who have spent endless hours cracking algorithms. These same lads will give you codes for your dumps all day long without wanting any £$ for it. But if you want to learn the algo for yourself, nobody will discourage you from doing that and you will certainly be pointed in the right direction. But allow ALOT of time.

Either that or wait until somebody (who did not crack the algo themselves) gets hold of the formula and publishes it free for all. Happens to all algos eventually...............
