I flashed latest KGL 2.83 but encountered problem: sometimes on first boot in the morning, touchscreen is not responding. Also, once there was mess with boot logo changed to generic Android and I was not able to enter factory settings as password was not recognised.
These problems occurring occasionally, not on every boot.
On the other side, it looks like radio reception / station finding is improved.
I wonder if anyone else tryed upgrade of KGL to 2.83? Do I have to change something in Factory settings (I don't understand Malaysk post on MCU list page)? Anyone expired similar issues?
Where did you get v2.83 from?
edit; sorry, noticed MTCB unit not MTCD...
Hi there, i am also planing to upgrade from MCU KGL 2.80 to 2.83. Main reason ist a very poor radio signal. So, may i ask how things went on your side?

Well, I stick with 2.83. occasionally it still freezes touch screen on boot. But I discovered that pressing button to turn off and then turn on the screen resolves issue ( I have he button for that)
I think radio reception is bit better with this than 2.80 though.
Hello all,
I hope you can help me with an issue I have with my PX5 MTCE head unit for a Toyota Corolla E12.
MCU: MTCW-XRC_V2.79k_1
ROM: Stock px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20180126.092422 test-keys (this was installed after Malaysk Rom did not work as expected for me)
So here comes the problem:
I have installed an after market backup camera. It gets +12V and GND from the reverse light. I used a wired setup and also a wireless transmitter with a reverse trigger line to test were the problem is. The reverse trigger line from the wireless receiver or the reverse trigger line (which was connected to the +12V from the backup light) is connected to the reverse line of the head unit. At first it works very well and the HU switch to backup camera when the reverse gear is in. But after a couple of tries the picture of the camera freezes. The HU will switch off the picture when another gear is chosen but when the reverse gear is again selected the same frozen picture is shown. After a couple of tries the HU will start to not even switch to the backup camera even if the reverse gear is selected. It only works again if the HU will be disconnected from the car power supply. Then the whole problem starts again.
What is here the problem? Is it a hardware issue?
Kind regards,

Hello Volcano, try to use a 12v filter or change the 12v input.
I have this exact same issue with my Eonon PX5 in a Toyota FJ Cruiser using the stock reverse camera. No idea what is causing it, but will see if I can find some sort of filter for the reverse input. Anyone else experienced this one?
Hey not sure if this applies to everyone but for me, I had this same issue and it seemed to go away after I noticed my unit wasn't grounded very securely with the cars ground.
I just connected a wire to the metal case of the unit and ran it to an unpainted metal part of my car and I haven't had this issue since.
There's probably other reasons why this issue could happen though.
Good luck!
Have the same problem with my px5 MTCE head unit (MCU KLD v2. 87) with installed hal9k rom. When I put my car into reverse before the android system is started completely. My whole unit sometimes freezes in boot logo. When I switch to reverse and back to forward and back again to reverse to quickly my reverse camera freezes with the last picture seen. I read in another post that it could be fixed by updating the MCU version but I first have to try this myself.

You might be onto something there! Last night I upgraded my MCU from WWW v2.88 to KLD v2.94 and i haven't had the problem reoccur. Granted I haven't driven much since last night but I will keep you all informed!
So I installed a new MCU version on my px5 MTCE head unit. I used the BD375xx Sound Processor Mod from Wadzio, MCU: MTCE_KLD_294bd.zip and as far as I can tell the problem with the reverse camera freezing is now gone. Thanks to the MCU mod my sound is now also way better than before so If someone has the same problem you should try a newer MCU version and maybe even use the modded version to get better Sound.
Great! Mine is going fine now too, so I think we have this one solved!
Thanks everyone!
I have had this problem reoccur once since updating the MCU. I'm pretty sure it is due to interference. While I was reversing, my partner turned off the climate control fan and at that exact moment the reverse display froze again. I had to reset the unit and it has been fine ever since.
i can confirm i upgraded the MCU from MTCE_LM_v2.88_1 to MTCE_HA_v2.99 and initial indications are, my problems is gone.
Problems;
- putting in reverse the camera worked for between 30s - 2min during daytime before screen went blank
- putting in reverse the camera worked for up to 30s at night time when infrared was used before going blank.
Will do further testing, but so far so good, seems to hold the reverse pic for extended periods. (picture flickers more than on previous wince unit thought)
Can confirm, i was getting the same issue, reverse camera image getting frozen, i updated my stock MCU from MTCE_HA_2.75 to the the latest 2.99 i could find, the problem seems to be happen less frequently but still does from time to time, usually when i turn it on first in the morning. Any further help would be appreciated.
I have se same problem, sudendly the screen frozen on reverse. on V2.99
Updated to 3.06 MCU, and turn off the parking lines on de PX5. Problem seems solved.
Seems that in this 3.06 MCU version, the reverse camera try to delay the reverse image signal, but no problems till now.

Parking lines were already off, gonna try and update to 3.06 later today, will post any findings, thanks for the help.
After some days of testing i can confirm that the problem still persists even after i upgraded to MCU 3.06, i wonder if my rom version could have something to do with it, currently using
ROM: Stock px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20180809.101522 test-keys, maybe try hal9k or malaysk.
Can anyone that has solved the issue by upgrading the MCU, tell me your ROM version?
Thanks.

Did you try 20181210 using a full wipe info. on the update?
This is my case, first used 2.99 and de november update, then installer de wadzio mod 2.99 and all were fine,
Then installer the 20181210 version and the freeze problems starts.
Now updated to 3.06 and seems solved. but is has a 5 seg delay from parking to reverse, and passing from drive to reverse has no delay.
Yea sadly upgrading to 20181210 with v3.06 didnt fix the issue. Running out of ideas.

Try this version - it's solved my issue completely (root required)
1) Browse to directory /system/app/MTCBackView/
2) Rename MTCBackView.apk to MTCBackView.apk.old
2) Rename oat directory to oat.old
3) Copy the attached apk to /system/app/MTCBackView/
4) Rename the new APK to MTCBackView.apk
5) Set permission on new apk to 644 (rw-r--r--) or 666 (rw-rw-rw-)
6) Put car into reverse and check that the app loads correctly.
With this apk and MCU KLD v2.94 I haven't had a single freeze for 2 weeks. I got it from a ROM image that Eonon sent me to attempt to fix this issue. They stated " our technician replied that there is the system error or conflict"

Hi guys,
I bought andoid car system Wondefoo with PX5 (octacore) + 4GB/32GB with DSP chip for Ford.
I have serious trouble with this car system - after switch-off car radio went sleep, but sometime when I switch-on car and radio wake-up, system beeps are working, but player, or FM radio cannot work - I have to push reset button and after reset it works until radio going to sleep and wake-up.
Did anyone simillar problem with PX5 radio??
Hi, I have similar no sound problem with Wondefoo PX5 4GB/32GB DSP unit (for VAG). This problem happens only when system wakes up from sleep, never after a cold boot. In my case, system beeps are working but otherwise there is only increased amount of white noise from the speakers. I haven't found a solution, except for disabling sleep to force a cold boot every time.
Another annoying problem with my unit is that Wifi and Bluetooth are often unavailable after a cold boot. Wifi adapter MAC address is set to value 02:00:00:00:00:00 when this problem happens. Rebooting fixes also this problem, and after a successful boot Wifi and Bluetooth work fine unit next shutdown. So , I think it could be a software bug in initializing the radio chip. Have you seen this issue with your unit?
What is the software version on your unit? My radio has MTCE_XRC_V2.89_2 and px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20180706.161540 test-keys.
have either of you guys found resolution to this problem? I don't have an issue with the audio, but after waking up from sleep my Wi-Fi and Bluetooth no longer are available. My unit is a seicane model, but it has exactly the same build number and MCU version. Their support or telling me that I should replace my Wi-Fi module, but seeing as others are having the same issue I would think this is a software problem. I have about 10 days remaining on my ability to return it to Amazon. And I'm leaning heavily towards doing that. Unfortunately I really like their custom faceplate match to my vehicle.

I haven't found a solution to the Wifi+BT problem. I tried upgrading system software to the newer version that is made available in this post but it did not fix it.
I have started thinking that perhaps the Wifi+BT issue could be related to bad electrical connection between the motherboard and the radio chip. Now that the weather is colder, Wifi and BT never work when starting the car in the morning. Anyways, this is pure speculation. If I have time, I will open the radio and have a look.
That's a very interesting observation. I live in Middle Tennessee and it's recently started getting colder, and I've noticed that I have to do a restart twice sometimes. there have been enough random post about Wi-Fi and Bluetooth not working after waking up on various threads at different forms that I thought for sure this was a software issue. The manufacturer has offered to send me a new Wi-Fi module, and I declined mainly because it wouldn't arrive before my return window closes
Did you have any issues with being able to sideload apks? I can't do that. No errors it just blinks and goes back to the directory screen. I also don't have contacts or calendars listed as sinkable items in my account sync settings. Each of these individual issues aren't enough for me to return the device, but when taken as a whole it's a bit too frustrating.

I can't speak for the original two posters, but that doesn't address the problem after sleep. The max time is 1 hour, but obviously by morning, it's been longer than that, and the problem arises again.
FWIW, I just initiated a return of my Siecane unit (thanks Amazon) and have ordered a replacement. If it's a hardware issue, this should put it to bed. If the problems remain, it's going back and I'm trying Joying or Pumpkin (or anything other than Siecane). Thank God I bought this on Amazon and not through AliExpress. Certainly worth the higher retail price to have that protection.
Have the exact same issue with my BT an WLAN and also the no sound Problem. Annoying. First few months the unit works great without the problem with WiFi and BT. Now the whole radio sucks like hell without any Connection. I will try order a new BT WiFi Module for a few bucks from AliExpress. Search WLAN px5 there.
I have the issue with white noise after wake-up from sleep mode on my Eonon unit PX5, Android 8. No sounds, just white noise and beeps when I touch the screen.
I installed Malaysk ROM but the problem persists. On cold starts, the sound is normal.
I'm having the exact same issues as described by you guys. PX5. Android 8. Hal9k Mod v3.1. Newest MCU flashed.
No sound after fast boot no matter what. Sound works perfectly after a cold boot. I will donate $10 to the whoever can fix this issue or find a good workaround via paypal.

Hello All
Here is the solution
I had the same problem since the beggining. The only solution was that i put the settings at SETTINGS > CAR > EXTRA SETTINGS > 30 sec
It did do the job but as you guys mentionned the radio was always starting after deep cold instead of sleep. It was still pretty fast but hey who doesn't want the screen to appear right away.
Like the last post, I did update to Hal9k Mod 3.0 . I did try again, same issue.
I was told to update the mcu. So I did to the mtce_gs_v1.94
And here is when everything was possible .
I know that the issue we have is because of the Amp of the bose system that for some reason is not starting after or something like that (don't remember exactly since i read that months ago)
So by updating the MCU, after restarting I had no sound but white noise (like when you listen to radio but there is no channel)
This is when you have to go to Hal9k mod settings.
then in manage applications. then you gotp applications that do not close when sleep and you choose ''amplifier''
and voila
hope it helps. I did try 6-7 times now and no problems anymore.
So have fun and thank you for the donations
Let me know if need some pictures
What you're saying makes sense to me but I don't have an "Amplifier" app to chose. I've even selected every possible app from the dropdown list and still nothing.
It might be because I have the MTCE patch form here https://forum.xda-developers.com/android-auto/mtcd-software-development/mod-cs-x-mod-mtcd-e-mcu-firmware-t3816042
I'll try with another firmware to see if it works. I have the XRC system btw.
Just in case those of you that are on this thread haven't found the solution to the wifi/bt when cold, look here: https://forum.xda-developers.com/an...o-wifi-bluetooth-waking-t3852206/post78313081
It's a long thread, and the solution appears around page 7-10. It is a hardware issue - an incompatible IC that needs to be replaced (or main board needs to be swapped). Resellers have fixed this for some that are still under their year warranty.

Hi, try putting the ACC shutdown timer on 30 minutes. see if it helps.
the setting is located in Settings > car > extra settings>
Hello,
I bought a Wondefoo Android head unit for my BMW E46 from AliExpress.
The problem it has; it does not save time when going into sleep mode. For example: When I come home from work at like 1800hrs and turn the ignition off, the radio goes to sleep. The next morning when I start my car at 0800hrs, the clock still says it is 1800hr. So it looks like it just pauses the time..
The funny thing is, when I go to the "Shutdown delay when ACC OFF" option and change the value to 1 hour, it saves the time. I don't really like this option because of the long boot time.
I contacted the seller, but I guess he is feeding me bull****. He sends me dmcu.img (226kb) files to update the MCU. When I follow his instructions, the head unit just says: "Not find mcu file!".
Since it does work when the head unit is shut down completely I assume this is a software issue, which might be fixed with an update, but I can't find any. Here are some other things I tried in order to fix this issue:
- I tried to use the GPS time (doesn't work)
- I tried to use the network time (doesn't work)
- I installed the Google Clock app (doesn't work)
- I gave the clock app permission to use everything
These are the specs of my head unit:
Model and hardware: rk3368 (1024x600)
Android version: 9
Build-number: rk3368-userdebug 9 PQ2A.190205.00. eng.hct.20190409.160431 test-keys
Kernel version: 4.4.167
MCU version: MTCE_CZ_V3.10_2
CPU: Octa-core Cortex-A53 @ 1.5G
Does anyone has a solution for this?
Thanks in advance!
Probably missed because you've posted in the MTCB instead of the MTCD/E forums. This is a known issue resolved by Android update. See MTCD forums.

Hello Marchnz,
Thank you for your reply. I am new to the forum and I posted into the wrong section indeed, my bad.
I am looking at this thread at the moment; PX5 MTCD/E Head Unit Discussion Thread [Rockchip PX5 A53 | Android 9.0 | 2/4GB RAM]
Guess I will have to update / flash my ROM. I will let you know if that worked out for me
Hi all,
A couple of months ago I bought a second hand car with a Android head unit. It's a pretty old rk3188, MTCD_MX_V2.59, Android 5.1.1. 1024MB. I have been reading quite a lot on this forum to get introduced into the magical world of MCUs and ROMs
The unit was full of apps and very slow. My goal is just to use it for radio and Android Auto. So I did a factory reset of the unit, and bought an Android Auto USB dongle. I am satisfied with the boot time and with Android Auto.
There is just one thing that is quite bothersome. If I set radio channels in the standard Radio app (find a frequency, and then hold a pre-set button until it displays the current frequency) this works fine for the rest of the drive. However, this configuration sometimes becomes lost. I think after the unit has been powered off for a full day or something. Mostly if I shut down the car, and start it again within an hour, the radio channels are still there. If the configuration is lost, it is lost forever, and I have to manually set the pre-set buttons again.
Does this issue sound familiar to anyone? Thanks a lot for you help!
edit: oops, I should have posted this in the MTCD section..
