It´s not recommend to downgrade MCU from QF03 to QF01 because you can brick your unit.

i cant see any setting with the name sidebar new. can you make me an screenshot?
ok thanks i think tomorrow i will downgrad it back. thanks a lot!
I‘m tomorrow in the car.. whats the second setting in factory or system setting with the pin 8888 … it must be panel key study or something else…
yey is it panel key study. but i think there i can only study the buttuns on the steering wheel, istnt it?
No… same problem after mcu update or firmware update… I search the same solution… at First I have think is setting 3 but it was 2… read it here in forum and works
German: NEIN nicht die MCU downgraden, du könntest das Radio beschädigen und dann geht nix mehr. Nur die Firmware kannst du ohne Probleme up oder downgraden!
As i say´d don´t downgrade the MCU. Only the Firmware you can down or upgrade without any problems.
Setting 2 Panel key study.. press on screen home icon then the button home on left panel and do the same with other buttons save and it works… if not reboot and it works
ok i will try it tomorrow! thanks! and le_mi, i dont change the mcu, i think its better.
for all: when here is someone in south germany and want to help me, is drive everywhere, to get fixed my problem. i am from munich.
Gibt kein Problem was nicht so schnell gelöst werden kann musst du nicht den Tank für verfahren da kriegst du schon ein neues Radio für sonst . Du kannst das Radio auch zuhause anschließen mit Netzteil und da alles konfigurieren und einstellen bis es läuft.
If there's no problem that can't be solved so quickly, you don't have to move the tank for that, you'll get a new radio for that. You can also connect the radio at home with the power supply and configure and adjust everything there until it works.
i will try i tomorrow. and tomorrow i make a short video or screenshot, ok? from the panel key lern thing
oh thats interessting. is it maybe the best idea first at all a factroy reset to do? and than qf001 to download and den mcu to download? thanks for your answer, i think that is a interesting fact. and what is the correct mcu with die qf001?
If it's true that recent HU with slightly different mainborad must use QF03 mcu (but we don't know for sure this yet..) I think it's not advisable to install QF03 mcu on HU born for QF01 mcu.
MCU file is related to the PHYSICAL hardware of the mainboard...

Doch die Firmware ist kompatibel, hab ich getestet. Nur bei der MCU bin ich mir nicht sicher und das werde ich bestimmt auch nicht versuchen, sonst hab ich n brick.
For sure the firmware is compatible, tested by myself. But I'm not sure about the mcu and I will do not test it, because of the possibility of a brick.
Take a look to androidhilfe.de. In your threat there are enough tips and all information you have to know.
Can anybody dump the QF003 MCU Firmware of a S6 Unit (BU32107 and TDA7708) by using factory code 45645600 and upload it?
I am facing screen flicker issues as well as inverted colors or simply a black screen while driving (Only when CAN Decoder is connected). To me it sounds like a faulty MCU Firmware although I never touched it.

IF it is still with mcu file stock and you have NEVER done any updates, probably the HU is defective, and I think it is better to notify the seller FIRST, without doing any tampering, so you can return it under warranty.
That is correct. I already contacted the seller
. As usual they are trying to play the stupid game. But I have eBay on my side so I will get a replacement soonish (hopefully). Nonetheless it would be still interestingSimilar threads

4I am writing an answer to my question dedicated to specialists of this topic who do not know how the device works, but only write their guesses, and they confidently think that everyone is stupid!
Changing the MCU version QF01 to the QF03 version is possible and very easy! Changing the version did not negatively affect my system in any way! The screen did not turn on from time to time and the seller himself told me to change the MCU, sent this version and told me how.
To change the version of QF01 to QF03, you need to enter the code 774411 in the factory settings and then download a new MCU. The board version has nothing to do with the MCU ! As I understand it, there will be no more MCU 01 version2Hi,
Really sorry for the trouble you are facing.

It's for Bd37534 tsc4745
Qf0031
Is it fixed the problem that cant independently change volume for navigation and music? Even though i have other volume for calls, music and navigation all have the same volume and it is very annoying especially when using google maps and hearing music at the same time.1
You can check if there is an app called "Carletter" after the system upgrade, which has the same functionality as zlink. If the app is not there, you can make it appear by changing it in the settings (where you choose zlink or carletter)I've got this update-file from the distributor for my device and after install zLink is missing
Any idea what to do? -

7The purpose of this thread is to consolidate links to firmware updates for these devices. Please do not use this thread for discussion. Go to the General Discussion thread for that. If you have a comment regarding one of the posts here please quote it and make your comment on the General Discussion thread.
In this thread post new links to update and MCU files with a brief description, the version, and in the case of MCU files post the devices it is for (S1-S4 or S5-S8). If you have a picture of the System Information screen that would be great too. Also if you have change logs you can post them here as well.7New february firmware from Hizpo seller . I have S8 HU
