I do not know how it is with other users, but for me this update 20230508 unfortunately began to break after a few days of use. At first everything was fine, but now the device reboots itself from time to time. Does anyone also have the same problem?

i use a newest software almost week, and just today it crashed and rebooted once. it it happened again i'll back to 0414.
i notice also two things. First, cold start always make weird sound change, for me the low and hi freq are boosted. You have to go to dsp eq and there move any bar, and all goes back to normal with sound. Weird.
Seccond thing. it is just a very small bug. If you set to display a outsite temp (taken from car via canbus), it appear near the home button in status bar, and the font is always white, in opposit to the rest of the status bar, which change font colour (white, gray, black) depending on a background of full screen app

And yes, all new what i notice in this version is the beep...beep sound when making a call. And if i have seted in a phone "play a tone when making a call" the HU also play this tone first.

Has anyone experienced that when you have enabled sleep mode lets say for 1 day, sometimes it sleeps but sometimes it shuts down. Even though the 1 day period has not passed. This bug is very annoying.

Yes, this happens to me too - i just set the device to sleep for 7 days instead. not having reverse camera until the device has booted is annoying, but something i can live with.

The rear cam (AHD 1080P) worked immediately if I engaged reverse as soon as I turned on the HU, if it was 100% off, with cold start (same thing if it was in sleep mode).
However, the dynamic steering lines may not work with a cold start.
At least with my S8 radio, rear cam via canbus, it's like this.

For those using Toppal AI (Standard or Pro version):

I noticed that with firmware 0414 (I still don't use 0523 firmware) Toppal has difficulty managing the command "Call (any name loaded in the address book of radio)".

Toppal "wakes up" correctly with the "Hei Top" command, but when I say exactly name as in the address book
"Call (name xxxxxxxx) it ignores everything, and after a short time Toppal screen closes, without making the call.

Everything is ok instead if you pronounce "Call (desired number)"...
Anyone encounter this?

Thanks a lot for the replies. It is so sad to have to wait for the bootup even thought you set the sleep at 7 days. They should fix this!

You should NOT have updated QF03 with files for QF01...QF03 is still new hardware, and no firmware and MCU files for update are available (at the moment).
The only solution now is to ask your vendor if he provides you with the QF03 files to restore with downgrade.

I flashed the qf03 to qf01, by inputting code 774411 before flashing, and nothing happened, I cant see any difference.

    File's title in chinese means " for a louder sound " . Not sure if it's a good idea for my poor speakers 😂
    Click to expand...
    Click to collapse
    This one actually solves the problem of overly loud speakers for some people. I used to set the gain to -15db， and all esp to -12db, then i can a suitable loudness. with this, esp can go to 0 and gain is still -15db, and loudnesses are the same.

    So in theory, the gain is -27db now, compared to the old MCU.


    Really recommand.

    AFAIK 0819 is the latest firmware available, never heard of 0824 untill now.. If someone have it or even an eventually September update, it would be nice to share it.
    Click to expand...
    Click to collapse

    I'd like to do some development on this system, so I'm looking for the newest available. But even if it is older than what I have, I'll take it. I'll take a backup of my current image via adb, but I'm not sure I can restore a dd dump back to the system (my thought is to try to extract the relevant images from the dump and merge them with an existing pac, but I've not seen anyone try that so far). Anyhow, I'd like a safe backup just in case.

    It is said to be better. sound and other features

    Click to collapse
    I don't think it will get better and I think I'm not the only one who thinks so. Only the volume scale was probably better scaled, but the quality was the same. But my device was rebooting itself several times a day and applications were crashing. But if you really want to, use the code 774411 in "factory settings"
