Stuck in reboot loop and random restarts. Px3 MTCD Dasaita. - MTCD Android Head Units Q&A

Problem: The HU restarts randomly and continuously. Sometimes screen goes blank and then reboots after 2 or 3 mins.
No specific app. Happens randomly in Radio, USB, Bluetooth or even when nothing is playing. Maximum paying time is 3 to 4 mins. But mostly goes in a reboot loop from the beginning. I tried searching online but couldn't get any solution.
@hotaudio Can you please help ? Please see the video to get a better idea about the problem.

Device:
MTCD Px3 Dasaita HotAudio
MCU is HA 1.6xx (couldn't get the rest)
Unable to get other details as the HU restarts before i can get to the menu.
UPDATE: Tried to enter recovery. Was able to boot to recovery after a few attempts. Even in recovery the HU restarted while selecting a factory reset. Before i could do anything the HU just restarts.
Unable to identify the issue.

Bump
@hotaudio Please help me identify the problem
@marchnz Can you please help me with this ?

Same issue with my Dasaita px5. Appreciate any suggestions.

Same here with px5. Some times it happens randomly but most of the time after 1 hours trip with navigator

Sounds like a hardware or powersupply issue.

[Q] Pioneer R1 Tablet not rooted and wont load past the animated logo

Hello,
My Pioneer R1 tablet the other night decided to do an automatic upgrade when booting up and hung for hours on 14 of 18 files updated. I rebooted the tablet for it to get to the home screen but come up with the error android phone services not initinalized and then froze. so rebooted and it got to the animated pioneer logo and just sits there never loading fully. Pioneer customer support sucks with helping and the tablet has a reset button on the back in a pin hole. I pressed that the tablet turns off. The tablet still stuck on animated logo.The tablet was running stock jellybean 4.2. The Pioneer people didnt want to do any troubleshooting. told me to send it to them to fix and that if they found anything wrong other than hardware issue i am liable for the charges on to of the shipping cost. I dont have money to just hand out to people who dont have a system setup for troubleshooting. Sorry for a long story but my question is is there anyone who can help me fix this issue.
Unfortunately I'm stuck with the same issue, tablet was running slow so I rebooted it, got hit with their "system breaking update"
Spent a better part of the day trying to find a way to reboot it into recovery mode and wipe user data/reinstall but so far no luck.
Fired off a email to support, tried calling but the wait time was 54mins last time I called.
Also there is a automated announcement while waiting for call time informing everyone that they "are aware of a problem with the tablet"
If I manage to get it into recovery and fix this I will let you know how
so after further testing :
holding reset for 30 seconds: fail
holding power for 10 seconds: fail
holding power for 1 min: fail
holding reset and then power:fail
power then reset:fail
opening case to disconnect battery; FAIL soldered to the board/battery wtf ?
pinhole on bottom of case between usb and power port doesnt sync up with a reboot option

ok well this was an counterproductive day
called Cs @ 1-800-421-1404
waited 45mins on a "20min" wait
talked to someone who informed me this was the wrong number to call for help with the tablet
called Cs @ 1-888-999-0987
"we are experiencing a high call volume at this time, leave your name # and model number and we will return your call before the end of the business day"
waited until 3pm and called again finally got to talk to someone and it was horrible
I was initially told to press the reset button on the back, when I informed them that was not the issue. I was told to email [email protected] and detail my problem, after around 10mins of this, I was put on hold where 3 different ppl picked up and re-asked my problem. Finally when I asked to speak with a supervisor I was told he wasn't there.
When I explained that this is not uncommon in tablet from time to time, ppl forget what they used as a lock code, or one of their children played with it and put a passcode on the device. I was informed that they cant give me any further information because pioneer hired them to field tech support questions and they aren't part of pioneer. The whole reason they cant just tell me how to boot the device into recovery is they dont know, you see pioneer failed to give them that crucial piece of information.
supervisor is supposed to be calling me back tomorrow so lets see what kind of bs this is.
more then likely I will be de-soldering the battery leads from the board to force it into recovery tomorrow afternoon/
only thing I've found out so far thru trial and error is :
power on ,hold power till first logo, press reset and hold. 3-5 seconds later screen flashes white once (either turning on or off)
tablet off, insert usb connected to pc, rapidly tap power and it will stay on the charging screen , pc then recognizes device as libusb-win32 device "Worldcup device"
still no recovery mode
ESI is actually responsible for the tablet as pioneer leased out their logo for the tablet.
This is why there is a ridiculous run around trying to get help from pioneer's cs reps,ESI got my problem sorted.
look for a stock rom dump soon.
so what files would be needed exactly....
so far I have :
aml_logo.img
boot.img
bootloader.img
cache.ext4.tar
data.ext4.tar
logo.img
recovery.img
and still have to copy over system.ext4.tar
packaged rom file!
ok so after following this thread :http://forum.xda-developers.com/showthread.php?t=2195858
I ended up with this Pioneer r1 stock rom , anyone who has a stuck pioneer want to try ?

I've been doing some searching myself, since I've got a soft-bricked R1 (Father-in-Law didn't want it any more), and from the looks of it, reflashing AML8726-based tablets is done via a rescue-SD card, or using a manufacturer produced USB burning tool:
http://www.slatedroid.com/topic/41478-how-to-unbrick-your-amlogic-aml8726-mx-series-tablet-v20/
So it appears that the tools are out there, but I haven't had any luck finding the device-specific files that will help.
I don't suppose you manged to find a way to contact ESI's technicians without going through the support number?
There is a recovery mode i unbricked mine just a few day ago need help finishing it it's very unstable
Sent from my SM-N900T using XDA Free mobile app
Could sort of get mine to boot...
My r1 crashed while watching a video and when I tried to restart it was stuck on this pioneer loading screen. I noticed if i let the battery run all the way out I could then get it to load up... but was greeted with dozens of error messages. This program has stopped this program has stopped. Every two seconds another error so trying to get on to google play for a scandisk app was pointless. I chose to restart and... back to Pioneer loading screen :/
Anyone ever locate a stock recovery flash for this tablet? TBT-7R1-P can be flashed via adb and ImageBurnTool. I have 2 tablets that 1, I do have CWM installed but need to connect a mouse to navigate (using a usb mouse plugged inthru an OTC cable) and nothing to restore since I'd wiped it.

Hizpo Headunit with inverted screen

Hello everyone. I’ve got a hizpo stereo that a friend of mine give me a few weeks back. The numbers on the side of the radio is ADY17009. It’s running Android 7.1.2. The problem I’m having with it is the screen is inverted. I’ve tried the reset button tried erasing everything no luck. I tried accessing developer mode pressing build number 7 times and it didn’t let me access it. Anyone know where I can get a copy of the stock firmware and operating system on this thing or can I upgrade it to the latest and hopefully it will fix the issue. I can’t sign up on hizpo website. Every time I try to I get a connection timed out error.
Anyone?

Cold boot problem

hi guys,
i recently upgraded my mcu to the sound patched version. sound is much better, but now the dam head unit cold starts every time. when before it almost never did. any ideas? i have already, factory reset, wiped cache, loaded my old mcu settings(like recommended saving them before the mcu update.) but still the same..... i have tried 3 or 4 different MCU's all with the same result. i read there is an option in extra settings, but mine doesnt have any option there except "play music for usb/sd card on start" or something along those lines.
Any ideias? its really anoying, as backup camera only works 30-40 second after cold start....
ps: my first mcu was mtcd_gs_v2_23_1, its a px5 unit. running stock rom, android 6.0. xtrons for the bmw e90
any help greatly appreciated.
anyone?

Pumpkin brand PX30 MTCE HT - seeking MCU update

Hi,
I have a PX30 head unit with Pumpkin branding.
I've updated the ROM to Hal9k which is great but the unit often fails to boot sitting on a black screen. Repeated attempts to reset the unit, and it eventually turns on.
Auto sleep is not working either so its always cold boot, even if the unit has only been turned off a few seconds.
I would like to try updating the MCU software but cannot find a file.
The version info is: MTCE_HT_V3.60_1, Aug 14 2020 10:19:07
I have tried to register for manufacturer forum to ask there but didn't get a response for account approval.
If there is a newer version that would be great, equally the same version or an older version that is known to be stable could also help me.
Thanks!
Looks like I managed to answer my own question, I found version 3.71 on a German forum, here is a link to it.
210.4 KB file on MEGA

Still don't have the sleep working, if I change it to delay shutdown or sleep it makes no difference and its a cold boot every time. I've checked my wiring and I'm sure the unit is still getting +12v from the car when ignition is switched off.
Anything else I can try or check?
Hello, try if you don't have Default power status - OFF: Factory settings/126/Other/Default power status - set ON or if the radio does not remember saved stations, then set: remember last state.

Hi, I tried this, the power settings don't make any difference.
If the unit is only off for less than say 1 hour, it will boot up again OK. It's not instant on like some youtube videos, maybe 10-20 seconds. I guess this is still standby mode?
If the vehicle is parked overnight, unit will not boot, just get a black screen. It takes several (usually 10+) attempts to reset it before it eventually boots.
This is really annoying, is there anything else I can check? The only thing I didn't change yet is the "customer type" number, would this make any difference?
Changing the customer version is not recommended, serious control errors and sometimes a black screen may occur, but it is up to you if you take that risk. Sometimes a new MCU update will make this change. The last number after the underscore indicates the customer version, MTCE_HT_V3.60_1, the last one is 1 so the customer version will be 1. If you have updated the MCU this may have changed. It is best if you have saved the factory settings in the dmcu.cfg file, with this file the MCU will be updated and all settings will be returned to the original settings. Factory settings - EXPORT button and save the dmcu.cfg file to external storage, if you do not specify a path, it is saved to the root directory by default. If the error was caused by the update to Hal9k, then the problem may be with this update, try to update again with wipe data or reinstall the original ROM. If that doesn't solve the problem, try a different car type in the canbus factory settings. Or the canbus adapter may be faulty.
Thank you, that is helpful. The unit was already doing this before any updates, I was hoping that updating the ROM and MCU would help but it seems to have made no difference.
I don't have a canbus adaptor.
