Rebuild a file J TAG

[JunioR27]

Good morning:-)
There are some pious soul, that I will give a minimum smattering on how to rebuild a file JTAG?
I explain my misadventure.
A short time ago while rimappavo my clio rs 197cv I accidentally slipped into writing a mod file, but that was not my car:(
Result? The machine part,
After various information requested here' and' I' was recommended to buy a device that was able to connect JTAG.
Someone Can explain me how to rewrite the file ori on the eprom using the JTag connection?
I have been told that rebuilt the file, but I don't know' by ch start:(
Thanks.

Hello Junior writing done via the serial port(obd) ??
the jtag method, and a method of reading the writing of the ecu directly on your pcb cio? with the ecu open to tour e xxx on special predispositions more some wires soldered with various resistances at various points on the motherboard(pcb) depending on the ecu...
according to me you do not have to rebuild any file jtag because precisely the jtag and only a protocol of reading...
to the maximum you need a full backup of your ecu with the same numbers on the sw and hw and restores your ecu always in the jtag obvious...
you what tools do you have??

[JunioR27]

On the rules it says not to advertise tools pirate:-)
For writing, I used a cock v51 and Jtag a Ktag,
How do I find a backup file?

[sportknight]

you can not connect jtag and rewrite the original file?

sorry,but how did you read and write? and why? now you can not do what you have already? done?

[JunioR27]

I had read and written in the obd, the ecu is a sagem s3000

Sorry let me explain better,
I had read in the obd, and I wrote the wrong file in the obd, now in the obd, I can no longer even read,
With the jtag instead, I can't write the file ori because I read it in the obd and ' 64kb against the 298 or more of the jtag, now a guy that I know is giving me a hand:-)

[sportknight]

great mange,you need to connect the jtag renesas to the ecu open as a document of the ktag or gallov53

you should read what you to be in the jtag and we should try to reconstruct the two files starting from the serial reading and reading jtag

[ugoboss]

have you tried the chicken in the mode recoveri to shoot him in his file ori? i.e. you select the car just select the file ori and do write without data, many times, the rewrites, maybe not immediately, but the rewrites.

[JunioR27]

No, I tried but after I corrupted the ecu eobd it was as if there was:(

[legendaryslave]

mail reading obd + jtag

[JunioR27]

here are the files that I've read=)
the only good is that the 64 kb read serially(good, so to say, seeing that had been remapped by a dog here in my part),
if anyone could riportarmelo the original I would be grateful to life=)

[JunioR27]

Aiutooooo:(

Riesumo the post because I wanted to ask someone what the programmer over the ktag could write to tour this sagem clio rs 197cv ?

[sportknight]

should make it even v53

[dvdtuning]

I have read that even the piasini the ago, the door to the bench.

Hello
Good reading in this ecu sagem 3000 (micro SH7055), are of 512kb.
Read only micro SH7055 (maps), the k-tag you have to leere 512kb.
Reading those posted to have a file backup (286kb) not serves to rebuilt the file.
Will I rebuild without problem, but I need to read 512kb.
