Hi if anyone wants to VCDS in Polish please contact me and I will with which it operates cable. I greet

[piotrekwoj1]

Friends do you have any idea what could be wrong?????

sorry for my English but if you have a problem with the VCDs, I, I can help you

In the first, cease to load identical photos, or reduce their size.
In the second, compare the diagram of your cable with datasheet a cable.
Of the third be convinced that you didn't make errors when "tuning" cable.
In the fourth, give a cable for repair to experts. It is very difficult to repair a cable if it is impossible to take it in hands.

Try to replace the GAL chip with jumpers. Replace ?tmega. Check soldered details.
I don't see in your photos, three jumpers which are necessary that the cable earned.

Sorry about uploading similar pics. But I try to be as helpful as posible for the kind people here that ask me for info about helping me out with my VagCom cable issues. I know that many people don't read the whole thread. In the future will be useful to post just the link with the previously posted pics. I also can use small sizes of it.
I was looking for a diagram too but inclusive some found here and other that KenshimPT share here have some differences with the board in the cable that I have.
After that as I said I bought that cable and I was been using during more than a year without any issue, without any mod, using the software that it comes with and without either open the interface. That is the reason than I am frustrated, without notice, without reason and in a moment when I urgently needed it, it doesn't work again.
I know about your replace comments of GAL, ATMega, etc.... that something is not working properly, but about your "three jumpers" comment sorry about my ignorance can you explain it a little more.

I know this could be expensive, and this post won't help you with your problem... but if you want to keep things easy with VCDS, buy a cable with BL chip.
Why? Because you don't need a loader and BL dumps works on any BL cables...
Regarding your problem, I am also without ideas... So do what Magadan wrote
Good luck

KenshinPT thanks a lot for following my post and helping me during this process. I know that you and magadan are right about my interface, something is defective and a new one with BL chip will be better, more stable and reliable, but my big question is: how do I know which cable uses the BL chip? which vendors do you know sells it?

What do you suggest piotrekwoj1?

[bibkare]

You must ask seller before ordering which type do they offer, ask them to show you picture of interface pcb and tell them that you will return it if they were wrong. All selleres have both types of interface even 3 or 4 different types

Read attentively previous pages.
"liviudiaconu" gave you the help twice.
Here the photo, on it it is possible not to do only darkly dark blue lines.

Also read all topic. Then will understand more.

OK thanks a lot magadan!!!!!. About interconnections in the PCB do you mean doing only light blue color lines?? right??
Of course before I need to follow liviudiaconu advice in his post: http://www.digital-kaos.co.uk/forums...ml#post1544532.

Then if I understood in general my cable is blocked now and I need to reprogram it.

[magadan]

That is the reason than I am frustrated, without notice, without reason and in a moment when I urgently needed it, it doesn't work again.

If you want to try to recover as was earlier, it is possible to make so.

...compare the diagram of your cable with datasheet a cable...
...Check soldered details...
...give a cable for repair to experts...

OR.
Replace atmega.
Make cable alteration as a liviudiaconu spoke. Check a cable.
If the cable didn't earn, replace the GAL with jumpers.
If the cable doesn't earn, return old atmega into place. Recover remote details. Try to replace the FT232R.
And if again won't earn, nevertheless to give to experts.

...do you mean doing only light blue color lines?? ...

And red lines. Read that told liviudiaconu.

and I need to reprogram it.

Yes.

[eliotroyano]

But Magadan according to your experience and the hardware issues that I am having with cable (in the case that cable is blocked only -led flashing red all time-), what will the best route? do I try to recover it? or do I make the cable alteration?

In your case there are two assumptions.
The LED blinks red if the switch of signals (GAL no test) is damaged, or flash checksum the wrong is incorrect.
Therefore I offered a method with changeover atmega.

But don't forget about bad soldered details. It is the most frequent failure in the Chinese cables.

.

Then at first the 7805 get very hot and LED turns off, I resolder ATMega pins and LED starts blinking red all time, my last status. Firmware/Hardware error.

Therefore I offered a method with changeover atmega.

Put jumpers to whole GAL16V8.

But don't forget about bad soldered details. It is the most frequent failure in the Chinese cables.

Well first I will try resolder all ICs in the PCB to know if it solve it. If not next step is modify it. My big doubt is why are 7805 getting very HOT and ATMega & GAL hot!!!!!

[mattydr67]

I suppose that you have to do what my frined liviudiaconu said.
And try to reflash your tool first.
(It is my opinion not a thereal solution becasue I'm not a medium)
Good luck

You already reprogrammed atmega in this cable?
If response "yes". That now it is necessary to delete details and to seal three jumpers.
And also these details can be heated if are faulty the GAL or atmega. Or the flash inside atmega is damaged.
Do any operation, I can't foresee all chances. Results of checks are necessary to me that I offered.

Cable is unmodded. I haven't reprogrammed ATMega. It is as it comes from the vendor.
