Any help with working dump for CarlinKit 5.0 [CPC200-2air / U2AC]

[Debugx00]

Hi, my CPC200-2 air is not fully working, only the web interface, the red interface with the phone selection for carplay does not appear. The indicator lights up pink all the time, even when I try to flash it via usb using the update *.img file for U2AC (I've tried many flash drives). The firmware is updated via the web interface, but this does not help, the red interface still does not appear, although the phone can be connected (flashing blue)

I also attach screenshots from the web interface and a dump of my MX25L12835F chip.

Added V5 Stock Flash Dump ;)

[Debugx00]

Tried stock V5 dump, no boot, no led :D
Tried stock V4 dump, boot, led yellow, no wifi/bt ahahah, wtf :D
My dump all ok, but not working red ui

[ludwig-v]

Just had the same issue playing with it, change the settings to set "Carplay" instead of "Automatic" for HULink Type ;)

[Debugx00]

I did this, it didn't help. 😁

[ludwig-v]

I have a new unit coming tomorrow to make a new dump, they changed the direction of the chip the chip on V5 (I fried my Wifi chip putting it the same way as before)
Backup must be done off-board it seems, made my backup on-board (Didn't have any problem on V1 > V4)

[Debugx00]

I made a copy using asprogrammer without connecting carlinkit to the power supply. Then I flashed it back and everything is ok. But the binary copy made by neoprogrammer didn't work for some reason.

I'll be waiting for a new dump.

[ludwig-v]

Could you try "MX25L12835F_CFW_20210830_LGX4358_BROADCOM_SSH.BIN" I just uploaded, I think your Wifi chip is the Broadcom one
(You will be stuck at activation but you can play with SSH)

[Debugx00]

Tested...no boot, no led(carlinkit), red led(boot)

Uploaded the new dump from the new unit, off-board to avoid any corruption ;)

[Debugx00]

As before, nothing new, the boot LED (small red and green diodes) flashes green once and no longer glows. Carlinkit LED does not light up.

It looks like I have one of the initial versions of V5 (CPC200-2Air), something between V4 and V5 heh :D

[ludwig-v]

I uploaded another .img found on their server, try it

[Debugx00]

I tried to upload the img to a flash drive, and again, the flash drive is not recognized by the unit.

I have even tried changing the partition table on the flash drive (MBR/GPT), based on the experience of detecting flash drives in Audi, the MHI2Q head unit, it detects only MBR/FAT32

[Debugx00]

Anyway, thanks for the help. Now I will try to communicate with the guys from carlinkit on aliexpress and send them tons of feedback from the web interface xD

[ludwig-v]

If you don't care about V5 you just have to reupload V4 dump, and reflash it via USB to fix Wifi connection ;)

[Debugx00]

I tried, it didn't work, my unit doesn't want to accept flash drives at all 😂

I also want to say that the firmware 2024.10.31.1827 is a beta firmware 🫡

[Debugx00]

@ludwig-v

They released another firmware for me, as usual it didn't help, but you can add it to the firmware list for U2AC (V5)

[ludwig-v]

Hi ! You can root your device by following: https://github.com/ludwig-v/wireless-carplay-dongle-reverse-engineering/tree/master/Flash_Dump/Tools
Maybe it will help digging yourself checking internal logs and also check if your USB drive is correctly detected and mounted inside /mnt/UPAN, Carlinkit is useless :)

[Debugx00]

Thanks, I'll try. They also sent me a new full firmware and again in the hwfs format, they said that not the img format is ok. xD

U2AC_AUTOKIT_Update.hwfs

[Debugx00]

@ludwig-v

Another of the latest firmware updates from support, also beta. As always, it didn't help, so they said there's nothing more we can do, you can try to return it to production so they can look at it.

As I wrote above, I tried to make rootFS for the u2w script to work, but nothing new, the flash drive is not recognized. I also tried to flash the dump from v4+u2w, and nothing either, the flash drive is not recognized, apparently this is a problem in the hardware part. Thank you for your help and such a lot of work in the research.
