motorola cracker security bit

[rimodar]

I've searched the forum for some answers regarding this question but i wasn't able to find any answers.I'm new in this kind of work -not a professional and i'm not planning to be one.I own some old programmmers for chips,and in some dil 8 eprom situations was able to decode some radios from various cars succesfully using software from this sight.The posible problem that i might have is when i decide to try to read motorola mc68****(05,08,705,11ak4,etc) chips with MC v6.2 or 7.0 to extract the eprom and read codes for some radios without deletind the MCU values.I didn't try this yet,but i want to, and i need some advice how to bypass security without deleting the information in MCU.Is this 100% possible by adding something to the circuit that i would be able to ONLY READ information without deleting it for every model for car radios up to say 2005?As i said,a don't own dump database to be possible to repair damage if something goes wrong,i want to do it one time and one time only without any mistake....Someone mentioned to add 150ohms from reset to 5V to prevent erasing,others read MCU,get FF-s and write new dump to MCU(i dont wan't this solution).I understand that security works by setting registar values for security,that after first unauthorised reading with this programer comand DELETE executes,and wipes everything.Is there a way,a modified schematics or maybe some trick to modify Mot.cracker to skip possible deleting of stored information in MCU.Is something like this -modifications possible for more types of MCU in a circuit that covers almost all types mentioned above?This question is only conected to MC not other more sofisticated programmers.Thanks in advance for all help.
PS: for some reason the downloaded stuff is remembered as downloaded and counted but the thanked button didn't generate any count number although i DID press the thank button.

There its ben many years since we bother with this old way programming motorolla MCU -s .I suggest you to buy one UPA programmer and sleep without problems.

The easiest way is to buy something that someone else chewed up and presented as final product.Even newer programmer products have problems when something new comes up,a new series of chips that the older program doesn't support,all sorts of clones,and you are in a need of buying new stuff again.I want to learn the old way,a when i finish this learning,i want to be prepared to change things myself without the need to buy new things again and again.This maybe old theme,but the way new things are made is the same as they were in the old days.Instead od max232 you have uart protocol,with the altered way of reading (USB instead of LPT)and more faster.The principal is the same.That principal of manipulating with security bit is my sphere of interest.....How do you bypass this in the new programmers,so i may use the idea for the old stuff?

What is the motorola MCU that you plan to work with. I've used the motocrack several times and it works in 05, 705 and some 08 without security bits. What is your problem?
If you only want to learn start with the datasheet of the MCU. Here's something. Good luck.

The one WITH SECURITY BITS.Just finished making MC 6.2 and read succesfully hc6811eo9 from beta4 radio,(plan to work with every model on MC software list),without security bit.Is there a way if the MCU is locked to bypass SEC.BIT with MCracker,without deleting eeprom?That is my question!No need to read datasheet,when every conection of the MCU's is on the net.But what isn't is the way how more sofisticating programmers solve sec.bit on new hardware and software?I want to use this idea with MC for now.That explanation might be usefull to me.How to UNWRITE SECURITY BIT ON A LOCKED MCU,and keep the information intact,or how to bypass reading locked mcu without deleting mcu if such thing is possible?Thanks for replying so far....

Motorola cracker can not read Locked mcu.You need special programmer example Orange5,Xprog-M

[rimodar]

I know that,i'm interested in THE WAY HOW for example Xprog reads locked chip.Does this have to do with the way the software reading of the xprog (the program itself has that possibility),or is this solved in the hardware way,say xprog has something in its configuration that allows him to read locks on the mcu and modify it without deleting?I've seen the schematics with PIC microcontroller,exept the PIC itself the rest of the hardware is more less the same as other programmers-inputs and outputs.How does the PIC while starting to read bypass the security???If it is a software solution on the PIC chip itself,can it be modified in a hardware way to be used with MC???That is my question from the beginning,something to add,modify to simulate the reading without interfering with the delete command on the MCU.....What terms must be sattisfied with the locked mcu at start,what needs to be set prior to start reading,that the say xprog programmer has and is able to read what MC can't...what makes xprog that much supperior?

Interface end soft moto V7.0

[rimodar]

RadioChip said that Motorola cracker can`t read locked Mcu(it can lock it,but can`t unlock it???),i have a schematics with i think 74hc245 combined with max232 as a MC ver7.0,for which is said that it is a worse version than 6.2.I didn`t try this schematics,but why is it (if it is) superior to other two versions?Can it read locked mcu?Thanks for the schematics,but i need diy version with working software to unlock mcu without deleting.....

Motorola cracker is my software but 7.0 is fake. Last release was 6.5 And doesn't support security skip.

Hi
Nice to have you around.

This is a latest release v6.5motocrack.jpg

Hi

I don't think that the programmers for the Motorola chips bypass the security.

There is a software on the site here which if i am not mistaken will give you the security bytes for Motorola chips.

[lkavan]

If you know how to skip Motorola secbits, maybe, I can try to add this feature to Motorola cracker. But I think, you cannot use well-known interface only :-(

Hi
What have you been using as equipment to read the chips?
