Disassembly of the fake mini VCI cable 

beachbummm69 UPDATE.. WARNING. the software is counterfeit and full of viruses. I just spent 5 hours formatting my laptop after AVG found the viruses but could not remove it all...god knows what its doing to the computer in the cars...I got mine off amazon but they sell this on all auction websites

what country did it ship from and what version of tis ? how did you program a used key ? as mine keeps rejecting me. I either need a pin code and reset ecu method or add individually but it won't allow me on on a used fob. fcc Id matching

Do realize these Chinese knock cables can really fuck up and brick the ECU and computer control modules. They are usually of lower quality. You get what you pay for, when it comes to pirated junk. I advise to purchase the real thing from Drew Technologies. Its only $495 compared to the full kit that will run you about $5,799 that comes with the toughbook laptop from techinfo.toyota.com.

Also you can't program immobilizers as you have to be a registered member of NASTF (National Automotive Security Task Force). Its only available for Locksmith or qualify service technician professionals with security credentials. www.nastf.org

Is this because AVG was picking up teamviewer or something?

Is there a way to test the cables? With some software and a DMM or oscilloscope? Or whatever is needed...

The difference is the chip package. FT232RL uses a surface mount L-shaped 28-pin SSOP chip package. FT232RQ uses a 32-pin QFN pin package. Both chips do the same thing.

With a proper cable, I don't see that there would be much risk with corrupting or damaging the ECU. Be careful with the customisation options, as they don't always work and may only work on specific ECU types. I don't think there is a log file kept.

Thanks for your comments. I lost one of my car keys a few days ago, and since have been surfing the internet looking for info about Mini-VCI cables and the TechStream software. I have worked with electronic circuits since 50 years and with machine language computer programs during 30 years, so I should be able to relate to the inherent risks of something going wrong, either with the software or the hardware. Given that the world is full of high and low cost products that plug into the car's OBD2 socket, I conclude that the chances of a genuine, but faulty XHorse cable frying the car's electronics are very low. So that leaves the TechStream software as a potential source of harm. Clearly TechStream is a package developed by Toyota to sell under license to auto technicians around the world. It is not surprising that the price tag would be in the thousands of dollars and not surprising that someone could get their hands on an original copy and find a way to circumvent the requirement to purchase an activation key by patching the program code before offering it in a bundle with the cable What is hard to measure is the probability that the pirated TechStream software would contain additional toxic code introduced to achieve some undeserved financial or ideological gain (identity theft / ransomware / botnet). While it is easy to backup or clone one's hard drive in order to restore to one's standalone computer if ever needed, there does not seem to be an easy way to backup/restore the car's ECU data using a trusted tool before allowing pirated software to take control of the bus. Unless one would use this cable often or with many cars, for me it is hard to justify the purchase of this cable and bundled software for a once in a lifetime use in order to save $50 at the locksmith if the purchase comes with a minuscule, but not zero, risk of causing hundreds of dollars of damage to the ECU. Nevertheless, the teckie in me would love nothing more than to buy the cable and plug it in and see what happens.

no it doesnt, the fakes are stuck in initialization mode which works fine for MOST techstream functions until you have to actually write to the ECU such as a TPMS reprogramming

The Mini VCI" cable was developed by a company called Xhorse. This is a copy cable which uses a leaked alpha fimware version. It works, but is very buggy, and cannot be updated to the official firmware because the CPU doesn't have enough flash memory for the real firmware. The sales of the fake cables so far out numbered sales of the "real" cable, that xhorse had to abandon all support for the mini-vci, because they were flooded with technical support calls from people who had bought fakes.

+ChumpusRex lol shouldn't take that opportunity to sell them the real off directly after brief explanation?

does this cable support latest i-hds software,and olso is it posible to erase fault codes with it

@@besmirmeta3742 yes this cable called Mvci by xhorse this is working with most of them ids hds tis tip vida also I use with sdd and lrh and if you need more help let me Know

This cable support j2534 hds honda?

I bet you can't clearly see through mine.And read numbers on the chips lol :)

So what microcontroller is needed to make it work?

have you tried this ?
