Hello
I know it's a long post, I'd be grateful if you read it to the end.

i used esys 3.30 and 4.38 psdz to update my bmw f10. i went according to the tutorial. i flashed zgw. while updating the other units by adding battery to my car, it gave an error towards the end. The car did not start, the doors did not lock, nothing worked. ista was not loaded on my laptop. i reached a person, he connected remotely. He did something from his own device, he said he would try ista, then he said he would try aicoder. He told me to start the car. everything seemed normal. according to what he told me, the psdz files were faulty. the istep version of the car still looked the same. however, the ista my mechanicman used showed the i-step version as old and said all modules were up to date. i installed ista 4.39 today. i also used 4.45 psdzdata. There were no units that could be updated in the update section. i clicked on the advanced section. i programmed the RDC module for testing purposes. it gave many error warnings on the screen. then it went away. I didn't do any encoding after programming because I was scared, the i-step version was up to date on all units after this process. But I didn't program the other units. I think my Ista is not licensed, it's the free version. I don't know what to do, I don't know how the guy fixed my car. Maybe it wasn't fully updated and stock. I'm very worried. I have esys 3.30 and other versions, ista 4.49 and 4.50 psdz. If esys and ista support it, I can use 4.50. Please, I am an industrial engineer in turkey. Repairs are very expensive here. I drive my car very scared. I used to be able to use eco pro sailing mode, now it doesn't work. Please help me by connecting remotely, please leave me a contact number. After these, when I connect to ista, I get the engine tuning detected error, I don't understand why my car is stock. Please help me by connecting remotely. I'm worried I'll break something.

I'm new to the forum, sorry if I violated any rules.
