I have a HCT-PX5-Rev16(LPDDR) coreboard that came out of a Witson PX5 RVT Android 10 series radio. I tried to install the android 10 version of Hal9K on it and now the unit/radio wont boot up. I get the Hal9k logo, then an animated android logo and then it just stays there (animation keeps going so its not crashing).
I've been trying to use the otg cable method. Cut a USB cable, soldered the resistors and got the cable to work. Windows is seeing the board no problem.
Trouble starts when i try to use Androidtool V2.84 to flash the board. Androidtool gives me the "found one LOADER device" message at the bottom so it does see the board, however everything i try results in an error message. After selecting a new firmware the "EraseFlash" function under the upgrade firmware tab gives me "Test Device Fail" for example. Everything under Advanced functions gives me error messages. I'm hitting a wall and i cant seem to find a way around it. Any suggestions?
Edit1: This also happens in Maskrom.
Edit2: I found a .IMG file called PX5_A10_IGV.img . I'm able to flash that to the board and after that the board actually gives me no information using RKdevtool 2.84. When i plug the board back in to the radio the screen flashes white a couple of times and then goes black. I've flashed the coreboard with the android 10 image

Hi. I have a problem. px5 only starts in bootloader mode. and i can't find any information about that px5 EMCP v7.2.
As you can understand i am a little confused about the updates.
I haven t tried yed.I want to know if it's ok to do this without any problem.Thanks
Good day I have had my Pumpkin Auto Head unit now since 2018 with a few headaches over the years that I can't ignore any longer. Mainly it freezes and crashes only option is to to a reset by powering off and back on and reconnect it to wifi and start my navigation again. Spotify and other apps just crash and shutdown along with a few other things like wifi not connecting sometimes and bluetooth working when it feels like it. I have contacted the manufacturer but all they do is recycle they're solutions by copying and pasting them to us customers. They ignore us current customers and just push newer models in frustrating, No new updates, no firmware update no Os updates. I was wondering if someone here can help me get something done as in updating this head unit so I can get a year or two more out of it as I will be purchasing a new car in that time. Until then id like to maximize the life if this head unit till then if possible. Thank you members in advance.

Device is not an MTCD or even a PX5 CPU device, so wrong forum. Try Android Head units forum.
Suggest discarding your device and buying a genuine Android Auto device or an FYT based UIS7862 device (FYT forums)
Hello marchnz,
I have a PX5 4G+64G head unit, MCU version MTCH_MX2_V3.84_1 jan 14 2022, after an update by mistake, the radio is dead, then I followed your guide to the letter, built a usb-otg cable, the windows 10 pc show rockchip in device manager, now I can flash in maskrom and now i can see recovery mode, but when i try to update with update.zip i always get the same error. What more can I do? Any reply is greatly appreciated, thanks

All answered in this and main OTG thread:
Thanks for the reply, I did that too, now I'm stuck on this error in the picture

Flash a full firmware and not just a recovery.
First - with full firmware loaded in android tool, ERASE FLASH first.
Past that, read, try, read. If unable to resolve - you're welcome to send SOM to me in NZ.

12This Post details how OTG/LOADER can be achieved to recover a corrupt PX5 or PX3 - any RockChip MTCx SOM
Update 2/2018 - anyone can make a gig without modifying their main board. BUT FIRST try a USB port, some have OTG out of the box.
From the work I've now done, Ive realised you don't need to hack your mainboard. You could temporarily solder connections to SOM or make JIG from header pins or make a simple cable from an old USB cable and two resistors: see: https://xdaforums.com/android-auto/...px3-5-headunit-mod-recover-flash-som-t3766892
Making a jig is necessary , as MCU cuts power to SOM after a few minutes during OTG.( Theory is the MCU watchdog senses an unknown condition in SOM, so resets by power off.) This can be bypassed by another mod to board, but much easier to just make a simple jig.
Need:
Remove SOM from mainboard.
Header pins to fit SOM (or solder temporarily to SOM PCB header)
USB male cable, cut one end off for wires to attach to SOM.
5v and 3.3v power supply.
1. Using schematic as guide. Connect earth and +5v pins. Connect 3.3v to [rtc_3.3]
2. Connect USB wires to SOM [USB-OTG] connections
3. Connect wire to SOM [ctl_recovery] and wire that to 3.3v.
Colour codes & Notes:
GREEN = PSU Earth [0v/(-)]
RED = +5v to PSU
BLUE = USB
YELLOW = +3.3 Via 3.3v supply OR use two resistors as a voltage divider 10K to 5v (R1 in image), 15k to earth (R2 in image), center = 3.3v
NOTE: SINK [CTL_WAKEUP) to GROUND (0v) if unit does not power ON
+5v = 1,2,3
0v = 4,5,6,71,72,73 and SOM Mounts
+3.3 = 20,28 (and possibly 9 & 15 - see note re. 15.)
With USB connected, power on. Use tools/load driver as described in recovery thread.
Q/Why hardware mods?
A/Mods were necessary because out-of-the-box (default) both my GS and JY boards would not enter USB OTG/Loader mode to connect it to a PC for recovery. We now know that a "jig" can be made without sacrificing your mainboard and simply wiring to header pins or buying a SOM header from say Digi-Key.
- Your MTCD may be different -so test first!
Q/My SOM won't appear in device manager or Rockchip Android tool
A/ If all connections are correct and power is Ok, force MASKROM as detailed here:

***Updated 08/Dec/2017 - Attach image showing USB Male cable connections to mainboard***
** Note - SD recovery boot card did not work for me on PX5 - probably due to version of [rockchip sdcard image create tool] - if anyone has a version that works, please post here.
Updated Feb 2018 - Android 6 SDCARD create tool is now available. Recommend SDCARD method and then OTG if SDCard method fails
Synopsis
My corrupt NAND was successfully reflashed using OTG "LOADER" mode as follows. It became corrupt , stuck in a bootloop and unable to enter recover following flashing a custom (bad) firmware image file.
- Using an MTCD GS board - which I have as a spare part - no display, only board.
+ Windows 10 x86 notebook with rockchip batchtools v1.8, rkimagerepack tool, latest PX5 image.
+ USB stick formatted fat32 with latest PX5 image
Do not do the below mainboard mods, this is completely unnecessary and posted for background on the journey to find a simple way of getting OTG.
1. Modified the board as follows:
A. Desolder and lift pins 27 & 28 of USB hub GL850 (thanks to xda user @ikerg and 4pda - for the lead)
B. Solder Male USB a cable to GS board USB 1 connections (See below attached image showing where USB male plug wires were soldered)
C. Remove pin to RK PX5 SOM [ctl_recovery]
D. Solder a wire directly on PX5 SOM header on [ctl_recovery]. This wire is used to trigger recovery.
Process
Initial recovery image: Because the PX5 firmware (OTG) "LOADER" process timeout appears to be approx 1 minute, it was necessary to create a recovery only image, as the 1.2gb PX5 firmware file exceeds the timeout, aborting the flash.
Using RKIMAGEREPACK, I created a image with a dummy zero byte system.img. This resulted in a 200mb image file.
- Loaded [rockchip batch tools] on notebook.
- Installed rockchip drivers
- connected USB cable to notebook
- held [ctl_recovery] wire to [mcu 3.3v test pad]
- Powered headunit on
- Notebook 'USB chime' was heard and board became connected, as indicated as highlighted '1' in rkbatchtools
- wiped flash
- selected firmware image without system created above and flashed to PX5
- powered off, removed PX5 SOM and refitted to JY headunit board
- On JY headunit, powered on, entered recovery via [holding powerbutton for approx 15sec - wait for 3 flashes of led] press once more.
Successful boot into recovery - started booting recovery and warned that system image was not valid. PX5 self-formatted system and awaited image.
- inserted USB stick with latest PX5 image and upgraded.
First boot waited for 5 minutes. Pressed reset and rebooted - successful recovery!
The warning here is that the PX3 SDCARD image create tool does not work for PX5 - even when using a PX5 image.
Why did I post this? Original Post:
I have a (JY) MTCD with HA 2..56 MCU PX5 stuck in a boot loop - "starting apps" appeared and then it reboots, looping. I was unable to access recovery via any of the standard recovery processes (e.g.holding the power button or boot into recovery via bootable SDCARD.
========================================
On SDCard boot - works OK on PX3 but on PX5, only a black screen is displayed without any text.
SDCard and button holding recovery methods worked OK on PX3 board, but not the PX5 Module when the SOM NAND was corrupt.4PX5 SOM rev4.0 MaskROM
Tracking the MaskROM pads on the rev8.0 SOM I found that exposing the tracks between the PX5 processor and the eMMC is not necessarily needed for the rev4.0 SOM. Take a look at the attached pictures.3PX5 SOM rev8.0 MaskROM
I have the confirmation that those round pads near the tracks between PX5 processor and the eMMC are for entering MaskROM!3Klyde OTG
Good news, bad news.
Bad news first:
- My PX5 2GB RAM is still bricked (or fried), can't access it via OTG.
- New PX5 4GB RAM has arrived, all good but no WiFi (refuses to turn on, still looking for the reason).
Good news (at least for the Klyde users):
No hardware modification needed for OTG/ADB access on the MTCD units!
Just need to adapt an USB male cable to fit the highlighted port on the back of the unit like in the attached picture.2Ok thanks. I first try it. If its not working I must wait if you guys can help with the maskrom mode right? Thank you guys for youre help
Edit: Just tried the OTG Method but also not working for me. Windows not reconizing my device. @marchnz Can you please show us in this Picture what to do to get it working on our px5 device?
Your connections look OK, but missing OTG_DET pin 28, which has +1.8v on it when connected to USB. (Detects when OTG USB is connected.)
As I have a jig made from a working motherboard, I am awaiting a header to mock up like you guys. I'll try making one out of wires like you have over the weekend and let you know.
I'm very keen to see more people get OTG so there's more people capable of helping out others that are that are stuck - others that are unable to make a jig might then have someone located closer and save on freight or having to replace their SOM
