kess v2 checksum error writing buffer. any solutions?
hi, i have a problem with kess v2 master edition 5017. i get error, checksum error writing buffer. there seems to be quite a bit of people who also get this error, just didnt manage to get a working solution. it all happened when writing a file with wrong checksums, it was 2 checksums if im not mistaken. kess did not handle that, and now car accepts only that file, no other, tryng to flash ori, or other modified tested working file, gives the error in the title, car wont start etc. tried putting diferent spare, but good ecu in the car, it did the same with other ecu too, so it seems like its a kess issue? i tried reinstaling ksuite, drivers. i did try flashing file with corrected checksums, still doing the same. its an bmw e46 me9.2.
can my kess sd card contents be corupted? or its all just an user error?
adding the file that started it all, with not yet corrected cheksums.
and as i heard originals do have same problem, from time to time.
regards

I have uploaded for you the KSuite 2.23 with checksum correction disabled. Try this with your own cks calculated.

Помогите разобраться в чем дело. Есть авто SEAT Altea 1.9 tdi BXE с блоком EDC16 которое уже когда-то чиповалось.
Слил прошивку и при попытке записать её же ksuite материться что неверные контрольные суммы.
Пробовал пересчитывать контрольки winols такая же беда.
-
#2
что значит матерится? где прошивка? может просит оригинальный файл? скрин давай матерков. А самое главное в этом деле это задать вопрос и свалить с форума

не в контрольках дело.
vcredist под свою разрядность винды установите.
Если не поможет, переустановите ПО для кесса.
Если не поможет, установите другую версию ПО для кесса.
Если не поможет — замена виндовс и снова по кругу все, что написано выше.

Извините, пока на работе не могу в телефон залипать.
Ошибка «checksum error writing buffer»
Скрин не делал нашел в интернете картинку такую же.
Ksuite и Винду менял, на ХР и 7ке одно и тоже.
С vcredist на днях попробую поиграться

Понял. Согласен.
-
#11
Наверняка когда машина первый раз чиповалась, прошивка записывалась не кессом, а каким то другим прибором.
В таком случае считаная прошивка, для кесса, будет с неверной контролькой.
-
#12
Тут как раз скорее всего проблема с ksuite так как kess по данному блоку edc16 (62/64 протокол) умеет сам считать контрольку.

#13
прошивка записывалась не кессом
Я конечно не помню на 100% но прибор был очень похож на кесс.

checksum buffer error
checksum buffer error
Hello, I have a skoda octavia 2.0 TDI BKD, EDC16U1, I read the the ori file with kess v2 2.53, I modded it via winols and I wanted to write it to the car, kess gave me error (checksum error writing buffer) I mention that i corrected the checksum in winols. When I try to write the file read by odb, It gives me RSA error. What should be the problem ? And how to solve this?
I will attach the files.
And can someone correct it for me ? or teach me how to make it work ?

Try with a real tool, your fake tool has checksum fault….

I’ve already corrected his checksum, his Ori is only bad because his tool scrambled his checksum on reading

no, it cant be fixed checksums, kess and ktag (even genuine) are kinda stupid tools and they will refuse to write, you have to restore checks to ori not fix them

I used an original to restore the checksums, then corrected his mod file…
He’s using a fake tool and it’s suffering from the common Checksum problem…
If he writes my file with good tool it will be ok…

Если верить форумам, как нашим так и буржуйским, у многих сохранение стока кессом на блоках Magnetti Marelli 7GV и в частности 03C906014xx, заканчивается ошибкой «Checksum Error»:
Полный размер
KESS v.2 5.017 Checksum Error
И далее: «ATTENTION: unrecoverable error — program must be restarted»:
KESS v.2 5.017 ATTENTION: unrecoverable error — program must be restarted
После чего приложение K-Suite закрывается.
Производитель)))) клона, рекомендует переустановить библиотеки C++.
Блогеры ютуба, советуют разную хню, которую не стоит вспоминать и из разумного, переустановить библиотеки из оригинального инсталлера. Кому интересно попробовать, оригинальный инсталлер <<здесь>>
Также, на форумах рекомендуют использовать K-Suite 2.10, либо 2.47.
2.10 найти не удалось, а 2.47 желающие могут попробовать. Лежит <<здесь>>.
Мне все эти способы не помогли. Забегая вперёд скажу, что сохранить сток так и не удалось.
НО, что удалось выяснить:
— kess без проблем читает и сохраняет прошивку, которая была залита в блок на заводе. Т.е. если версия ПО на наклейке совпадает с ПО внутри.
— если ПО было обновлено через VAS-PC, при сохранении kess вылетает с ошибкой.
К сожалению, проверить что он там сохраняет возможности нет, т.к. бинарник 03C906014AJ_9970 найти не удаётся. Имеется только *.sgo. Если у кого есть бинарник, откликнитесь пожалуйста — сравним хеш.
В блоках MM 7GV Kess пишет фуллфлеш, а не только калибры (странно, но многие акуетькакиегордыечиптюнеры и ни хрена не шиномонтажники, об этом не знают и с пеной у рта доказывают обратное… Ну, да ладно. Они же всё знают и консервы не шьют и вообще у них всё круто и дорого)).
Благодаря тому, что шьётся фулл, прошивки взамозаменяемы, что вверх, что вниз. Шьётся долго. Порядка 20 минут. Причём, в начале прошивки пишет вообще 50 минут.
Таким образом, имея в блоке 9970 мы можем без проблем залить сток или тюн версии 8591, например:
Я для себя сделал вывод, что Checksum Error при сохранении стока на 7GV бояться не стоит.
А вообще, конечно, как обычно, всё на свой страх и риск.
