Hi, Sorry for the late response. I did step by step as described. About Error, I've had it three times (Access Key should be: 20103 or empty (try both ways)), and in the third time, I saw ID. Yes, in russian forum, it was explained why SET ATST command to "16" is important. It's about reading speed. If reading too fast, he misses some digits or something else (not professional)

Here is my experience: https://www.briskoda.net/forums/topic/521024-kamiq-my20-mib3-update/page/5/#findComment-5933471 of course should read also original post: https://www.briskoda.net/forums/topic/521024-kamiq-my20-mib3-update/#findComment-5827723 Everything was going smoothly

Check in your system your software version, go to the Min-helper com, are that page found your software version. If yes, will show have you any new update. If, yes, than visit page Mibsolution.one, download one by one necessary version. I think it doesnt matter the car, because everything what you should looking for is Software (firmware) version

Hi, not sure what is correct one. Wasnt looking for that info. I had 088. But OCU update takes only 4-6min.. Do the update to 088 and then to 143. But OCU update i did only at the end. Some descriptions said that neceasary before etc..

Read an update from my side on April 2025. I have found an easier way, without OBD eleven, Excel, ODIS, etc... just an OBD adapter and carscanner. All necessary remarks were to follow, I placed. Costs and time saving way

I have updated to the 143... here it is the > LINK No need for EXCEL or for OBDeleven or USB cable or ODIS, etc just phone + Carscanner (paid plan, but max 8€ instead 60€) + ODB Bluetooth adapter, PC/notebook to copy files on USB or SD card. Read my post about that. There is all that you need to know.

My experience in one month with the updates: Have buyed only CarScanner (forever licence 8€) iOS instead, cable for ODIS or ODIS services, or OBDEleven for ~60Є. I had a 5-year-old Vgate OBD Bluetooth adapter Have Skoda Scala with MIB3 (Amundsen) 0156 factory (USB-C port) Of course, thank you all who did the primary job and created different ways to update yourself! 1. I did nothing else, just all firmware update 0156 > 0238 > 0268 > 0278 > 0306 or 0308 (not remember which) > 0330 > 0332 (newest) 2. The last step, 75 and 5F errors. It means OCU update to the 143 and 00071C00 (enable navigation) 3. For error 75, use the instruction from user r0bb10 > 5WA035284OCU143.zip instruction 4. interesting part and total could take only 15min (phone with Carscanner + notebook to edit file and upload on USB the files) > enable FEC 00071C00 5. Connected the OBD adapter to the car, opened Carscanner on the phone: 5.a. Carscanner > Settings > Adapter > Advanced settings> SET ATST command to "16" and "Use software flow control during coding operations" and "when reading data" (2 parameters): UNCHECKED both 5.b. I went to Coding and service > Long coding > block 5F > Access Key should be: 20103 or empty (try both ways)> checked the box "USE Custom ID" and in the field that appeared entered 3C0A, then clicked "APPLY". 5.c. For sure message ERROR will appear, but you will see a new field DATA: E0 A5 F3 2C 1E (it's my code, but you will have yours. Total 10 simbols) it's VCRN ID number and is necessary to activate 00071C00 5.d. Save that number, you will need it. 6. From MIB solution page, download the file "MOI3preh Solution - BEWARE wait for feedback on mibwiki" 6.c. Download to PC software via Google "010 HEX editor" and open the program > open MOI3preh file "full.bin" 6.d. Use FIND function and search for "564320524E" > use REPLACE ALL function and add your number, for example, my "E0A5F32C1E". 6.e. all number "564320524E" will be replaced with "E0A5F32C1E"> SAVE the file > copy two folders and two files on USB flash 7. Just do a regular update as you did with other files At the end, experience with CarScanner. Yes, maybe it doesn't have a nice UI like OBDeleven, but it can do a lot with it. Even changed some Themes on Copilot, etc. At the end easy to use and find what you need. I hope that someone will help and not purchase for some items more than 20€
