Hi, I'm pretty new to this scene and was hoping for some support and guidance from the community. I have recently purchased a 2nd hand car which had a PX5 head unit. I will post the device details below, but I was hoping you could point me in the right direction to download a newer and compatible firmware/mcu for my unit. I'm used to flash custom rom/firmwares on android mobile phones so I do understand the process itself quite well, it's just the firmware/mcu compatibility with this device that I'm unsure of. Thank you in advance for the support.

Hi friends, maybe someone has encountered something similar and can help me. I have a PX5 android 9 radio with DSP. Sometimes the sound completely disappears from me. There is no regularity, but I noticed that when I have no sound - the equalizer becomes simple, when there is sound - there are a lot of different settings in the equalizer. A couple of times I just updated the MCU and it seemed to help, although it was probably just a coincidence. Sometimes it is necessary to restart the radio very many times and the sound appears

MCU
MCU type discussed here is MTCD or MTCE (if your unit has not MTCD/MTCE type MCU this thread is not for your unit)
MTCE is a software upgrade for MTCD, so they are identical in terms of hardware
Manufacturers.
The Manufacturer is identified by the XXX when consulting the MCU information under "device information" [MTCE_XXX_Version]. Take into accout that you should always refer the MANUFACTURER name (not the seller) on the forums for help/assistance. Giving the name for the Seller does not give any information but confusion.
e.g: MTCD_HA_1.93_1 (MTCD Unit with MCU for HotAudio under 1.93_1 version)
e.g: MTCE_GS_2.75 (MTCE Unit with MCU for GESHI manufacturer under 2.75 version)

ANDROID 6.0 -> ANDROID 8 UPGRADE WARNING
Due to change in partition system and upgrade in recovery system, update can't be performed using the OTA Android 8 files over Android 6.0 as usual method (direct or Recovery) as it will result in an error (or could get a bricked device...)
The only available methods are:
1) Upgrade by using SDCARD slot:
2) Upgrade by extracting the SOM and connecting a homemade OTG USB cable:
Instructions for making the OTG cable:
https://forum.xda-developers.com/an...px3-5-headunit-mod-recover-flash-som-t3766892
For upgrading via OTG cable it is recommended to use Rockchip Tools for the Android 6 to 8 upgrade from a PC (to put the unit into "loader Mode" and then flash the supplied firmware)
Custom Oreo Firmwares:
@Malaysk has been released a prerooted Android 8 image with several improvements and modifications:
