Hello. Hope this is the right place to ask this.
I changed a setting under "factory setting" and now the HU wont boot up. The setting was "Default power status" changed it from on to off. I also turned of the canbus under factory setting and when i wanted to exit i needed to reboot and then it never booted up again. It might boot up but there isnt comming anything on the screen.
I really hope that someone call help me fix this.
My unit it this on. Bought on iceboxauto http://www.iceboxauto.com/opel-astra-j-2010-2012-android-60-b5754

In my px3 i set default Power status in "off" and i have no problem.
Did you try to hold Power button (about 15 sec. till blinking led lights) for resetting HU?
Sorry for my bad english

There are no fysical buttons on the unit. I have tried to hold the power button on my dash board but stil nothing happen
You can try:
1) reset button (if there is It, you can check under gps slot)
2) unplug the connector or turn off the fuse box to reset the hu

Press reset until you see light blinking (15-20sec). Release and press again reset until marshmallow logo appears...release and you will enter into recovery menu

1) There is no reset button. Under the GPS slot there is a very small hole but nothing behinde the hole )
2) I have unlug the connector to the HU and tried to have it off power for an hour or two and then try to start but still the same. Nothing show on the screen. Not even to android logo. What you mean with fusebox i dont know

I talked to the seller today and he told me to press the reset button next to the gps slot. When i told him there isnt anything behind the hole he didnt know what to do. Great :silly:
I got my unit up running again. Because i dont have any fysical buttons on my unit and i ****ed up the canbus setting the only way to wake the HU up again is to disassemble the screen and on the board there are some connection where you can solder wires to. One of them is "key1" and when i put i wire from that to GND the screen turned on. There is also a "key_rst" thats for resetting the HU. There isnt any wires on those so later i will make it on my own so i dont have to disassemble the screen if i **** something up
Hey , I did the same mistake with "default power status". I can get into recovery menu, is it enough to wipe the firmware(not MCU) of the device?
Thanks
Made the same mistake with this setting.
If I press and hold power button after about 15 seconds button lights come on and then flash. Keeping hold of button and lights stays on but screen is doing nothing.
Reset button causes lights to flash but then go out. Again nothing on screen.
Mtcd px5 unit.
Seems like something is going on because a message of 'other' appears on car standard fit display next to clock which is what generally appears when head unit was working.
Maybe there is combination of power an reset needed.
Eventually into recovery press and hold power button until lights flash then let go and press again. Took a few goes to get timing right. Then key was that I had an exported MCU conf file so I reflashed MCU with this so default power setting was back to being OK.

I have the exact same problem, I changed the "Default power status" in factory settings to off and after the reboot the system would not come back up. Odd part is if I wait a few minutes my phone will still connect to the radio via bluetooth. Seems almost like only the LCD is not powering on. Since I can still get to recovery would it be possible to get a copy of your MCU conf file so I can try and reflash? My unit is a KGL and I currently have the 7th Floor mod MCU installed on the radio. Any help anyone can provided would be much appreciated.

Never mind I was able to grab the modified DMCU.IMG KGL file from here, and then add the DMCU.CFG file from here, then throw them on the root of my GPS SD card, then boot into recovery and flashed the MCU. After the reboot the screen came right on. I just had to go into factory settings and make the needed changes for my radio.
I was stupid enough to did this same to my HU.
All because it draw 0.25A when in slip mode (ACC OFF).
I try to different options to drop power consumption and change this option in process.
Off course I have brick my unit. Any way to recovery it??
Dont have any hardware buttons no GPS slot. How to reset this unit??
Any ideas??

Suggest having a read through links in my signature. If your unit, which you havent said what type it is - is drawing 0.25A in sleep, then that's a problem.

My Unit is MTCE GS PX5.
It was unit with out radio module (xtrons for Freelander2) so i solder one on board. In process have to change MCU from GS to KDL to get it work. Then when unplug ACC cable from 12V radio going to sleep and after few seconds will constant draw 0.25A around 3W. I cant remember how it was before but previews owner sold to me because of battery draining issue. I believe its bit much as will drain car battery quite fast. So i try to find a way to eliminate this flaw. In order i change option "Default power status" to off and since that my screen is blank. Looks like radio is working as Bluetooth is broadcasting. I try to fiddling with it for bit more if not probably only option is to program STM32 with ST-Link STLink V2 Programmer. Maybe any ideas how to reset this settings.
BTW bit stupid to put option that can brick you radio in easy accessible place.

Just little update. I already order ST programmer and now wait for delivery.
When i have close look (and from different angle) on radio screen I can see that radio boot to OS and first page pop out. Just screen back light not working and touch as well.
Also Usb is switch off so no keyboard can be connected. Only option is to reset this setting but dont know how or programming MCU.

Job Done.
Radio back to live by programmed MCU using ST link.
Still problem with drainage but already order new MCU and will try to replace it as at the moment STM32 is very warm when on STBY (ACC OFF) so probably there is a problem.

Hey everyone,
I need a little bit of help. My Nexus is having a bit of an issue. I've looked around but can't seem to find anything similar.
The phone boots completely, shows the boot animation, shows the lockscreen with notifications. I can drag down the notification bar, turn on WiFi etc with no issue. As soon as I either unlock it or click on settings, the screen goes completely blank. Safe Mode does not seem to make any difference.
I've done a Factory Reset using Recovery mode and now after booting it shows the Language options for setup and the screen once again turn off. Pressing the power button after that gives a clicking sound but no picture. I've uploaded a video here https://gfycat.com/PoliteCommonAmmonite
Any clue what I am supposed to do?
Thanks for your help!

maybe hardware issue

I have similar problem.. turn on n5 and when not moving it works fine, I can get the phone on,
The screen flickers and goes dark or touch won't work are some occurrences. Phone still works ie gets sms and etc. With research for a few weeks. Seems that it's not software related but hardware related. I am hoping it is a flex cable problem or a loose cable problem which is cheapest. If a screen replacement is needed then it's not worth the work. Just buy a new phone. I got mine secondhand at a way cheaper price. Too bad cuz I like it it's nice enough for me.

I'm fairly certain this is software related as :
1. The screen plays the turn off animation (a-la old CRT TV) when it turns off
2. The screen turns off at the same time everytime it is rebooted (and before the reset would stay on until the screen was unlocked)
3. The power button still works to reboot the phone.
Hardware or software

To make sure it is not indeed a hardware problem we should perform a sort of "hard reset" (not to be confused with button combinations to reset the devices software) . Turn off the device if it is on. Take off the back cover, remove the six silver screws holding the plate over the motherboard. Once that is off you should firstly lift the battery flex cable up gently. (see sample pic) With doing this we ensure that all power is gone and no other components will be shorted. The idea here is lifting and reconnecting the the flex cables and wires to make sure everything is really how it should be. (resetting them all) Basically tearing it down. I would just unplug the battery and then unscrew the four screws at the bottom to access the LCD flex cable underneath the speaker. Lift and re seat the LCD connector and reassemble the phone (battery being last thing re seated)
It doesn't hurt to try this method to rule out the hardware side. If you don't know how or need help PLEASE contact me first for advice so you don't end up with a broken Nexus 5.
What will Hard reset rule out?

Two things.
1. question if done this process and the problem still comes back what does that rule out? If the problem does not come back then the problem was hardware?
2. I did reseating but did not reseat one cable or maybe all of the flex able connectors and the battery was still in place. and it was not connected last, rather it was first i just took connectors on and off and did not want to mess with the black wire as it was very thin and small.
Result of #2 was that the problem went away for a while, seemed to "help" but did not fix it completely.
unlock ur bootloader ! flash a rom and install any kernel which supports colour profiles like Elementalx flash then open kerrnel manager and change the colour profile to vomer_amoled if u like it! or back to stock!
Alright so I've done so far :
Reinstalled stock from scratch (Still the same issue)
Unlocked bootloader
Installed TWRP ( I can play around in TWRP with no issue whatsoever, screen doesn't go off)
Sideloaded Pure Nexus, GApps and blu_spark91 kernel
Tried scraping all of that and going with CWM and CM, still no dice (although the sound is different!)
STILL THE SAME #!&%$ ISSUE. But now I can select the language. When I click the yellow arrow, I get that same issue where I can't turn the screen back on. The power button still plays the lock/unlock sound through the speaker.
I should also mention the power button works perfectly when using TWRP or CWM.
I have no clue what the hell I am supposed to do now..... Please help. I've never opened the phone myself.
Hello, I would like to suggest a hardware cleaning of the power button. It may or may not help, but I assume you would like to try something different to remedy the issue.
https://www.youtube.com/watch?v=doPuXkQTGbc
The video shows how to remove the motherboard in order to clean the power button.
I had done this on another Nexus 5 that turned off randomly. I didn't want to replace the power button but cleaning it removed the problem for me.
So I started my CX-5 about an hour ago to be greeted by a black screen full of flowers. Literally. No idea why. This happened one other time, and it seems as though once it powered completely down, it comes back up fine. I have the timeout at 2hrs, so I have to wait quite a while to see if it's going to be ok.
I tried to reboot the unit by holding the reset button down, but all it does is put it to sleep. Actually, a short press caused it to mute (literally displays 'mute' on the display), and a long press puts it to sleep. Tried the press it till it goes off then release, then press again -- doesn't do anything but wake the unit up again.
The steering wheel controls all work fine. When I parked it last night I had the radio playing, and it was still playing when it started with the black screen. Volume and fwd-rev buttons on the SWC work fine. None of the capacitive buttons on the LCD do anything except home and power. Power puts it to sleep. Home displays the launcher screen (Car Launcher Pro).
If I press any of the app buttons in car launcher, they send me back to the black screen. Pressing the speed in the launcher switches to the trip display like it should.
Anyone ever seen this?
Anyone know how to actually reboot the thing short of pulling the fuse (if that would even work)?
The car has resistive steering wheel controls and *also* has a canbus decoder to tell the Bose amp what to go do with itself. I didn't actually have to use the KEY1 or KEY2 - I assume that the Mazda ISO adapter that they sent has this built in but I dunno.

That's happened to my MTCD a couple of times and seems to be when Android's user interface hasn't loaded properly for some reason.
Pushing a paperclip into the reset hole until it reboots normally fixes it for me.

Reboot with a paperclip as other guy pointed.
Your can bus not only plays with Bose amp....it gives you the reverse signal for the Camera as it is coded by can bus.
You have nothing to do with cables as they are properly wired for your installation

I have tried the paperclip method. All it does is put the thing to sleep. Doesn't matter if I hold it for 5 seconds or a full minute the result is the same.
the flowers thing is one of the default wallpapers
Hi !, try this......

I got the same screen in my HU but only when car launcher is installed. If you remove the launcher that screen will not show again. Maybe is an issue with the car launcher with the units. I am using an MX (witson) version 1.93
I thought it might be car launcher. I haven't had any issues in quite a while though.
Do you know how can I enter recovery / reinstall firmware on a Winston PX3 without any buttons? just reset.
The unit is made of Opel Insignia and uses the car button. The power power button only switches the screen on / off and nothing more.
Is stuck at the lollipop logo without anything else.
I tried all the method here... reset, keyboard without any luck
RK tools not working since is not seen by the laptop
Bootable SD, same... no luck.
Thanks in advance
I also want to know that, never find solutions at this time.
I have same car with same head unit, do you have a good radio reception?
Read here and tell us if it works ... on my witson px3 android 5.1.1 works this procedure to enter in recovery... good lock

Solved after taking out the unit.
The trick with power button does not work since on Insignia access to the power radio buttons is via canbus interface. Power button only switches screen on and off when not in Android... nothing more.
So solution:
Is easier if the unit is not mounted in the car, I have not tried to enter recovery after a reset, but maybe I will try sometime.
1. Disconnected all power from the unit... ACC & BAT disconnected
2. Prepared 12V power supply with on negative and two positive connectors
3. Connected negative to GND & one positive to BAT
4. Connected USB keyboard
5. Press right ALT (ALT GR on some keyboards) and PrintScreen
6. Connected the other positive lead to ACC (unit does not work if both BAT and ACC are not connected)
6a. Start pressing repeatedly on E (not holding E pressed, but press...release... press... release..... rapidly)
7. The boot logo shows (Lollipop...etc) and after a few seconds the unit reboots itself
8. Release right CTRL & PrintScreen and continue to repeatedly press on E.
9. The Recovery shows on screen.
Sweet success at last.
I put a USB stick with Hal9k room and selected install from USB and clean... waited for 15-20 minutes and everything fine.
Mounted the unit in the car after switching to MicroG and configuring apps.
Hope this helps others who have problems getting into recovery.

Hi,
Found solution, described in the previous post.
Reception is good. I had also a power amplifier mounted but did not improve reception futher so got rid of it.
Hal9k ROM with MicroG is much faster than stock one.
Have a new China headunit with android 7.1.2 and first there was no FM radio. Searched XDA and with password m123456 got into factory settings and there the radio stood OFF?? Changed it to ON and after restart it was there. But there's no signal, no sound, nothing. Anyone ideas?
Also, this is a monitor with no buttons. How do you get in recoverymode when there's no on/off button? I only have the reset possibility (little hole on the side of the monitor).

Did you select your country as well ?
If you mean the region for the radio in factory settings, I did.
If you mean region in Android, like date and clock? Somehow I only can set it manually. If I choose automatic date/time it stays on Chinatime?
And do you have your radio antenna Installed?
For going into recovery:
Press reseat button until you see flashing the button lights..(approx 25sec)
Release and press again until see your nougat logo.
Release and wait for recovery menu

Radio antenna, isn't that the microphone? There's no separate antenna plug? See https://www.seicane.com/android-hd-...hd-1080p-video-steering-wheel-control-s018848
Recovery; press reset button until you see flashing the button lights.. (approx 25sec) >> what button lights flash? There are no buttons
WOW would you look at that unit !! Does it drive the car for you too !!?? lol Judging by the pictures it must be on the box somewhere but when zooming in I cant see if/where it would say ANT..
Yes, looks impressive, car almost drives itself . Works very well, nice touchscreen, only no radio signal. Also the steering wheel buttons can't be changed. But they work well, although would be nice if I could customize them.
Sorry to say, but there's nothing on the box for a Antenna. The only thing saying something about an Antenna is on the big plug/connector witch connects to the original radio. On the attached picture there are 2 pins ANT. Does it use the original car antenna through the connector of the original radio?
It says that it syncs with the cars bluetooth have you been able to get and kind of sound with it ?
Your new unit don't have radio, the radio is from stock unit, you must have to connect your new unit in conjunction with the stock unit. And there is a "app icon" that switch to original menu and there's your radio.
You just change the stock screen for the new one and connect the original cable of the stock screen to the connection labeled car lvds
Cid6.7: yes, bluetooth works fine and the sound is good!
Hugovw1976: I did not know there wouldn't be a radio in Andorid. I can switch between stock and Android. But, when I go to Android the stockradio stops. The only way to go from stockradio to Android is when I push long the GPS button on the steeringwheel. Stockradio keeps playing and GPS (IGO) starts on the screen. I can go back to the radio but then the GPS stops.
Are you saying there isn't even a FM receiver in the central box?
Oh, and thanks for the replies, now we are getting somewhere.

I install a similar unit (the central box is the same) on a Audi Q3 an there's no radio.
Thanks, that makes everything clear. Do you have experience with the steering wheel settings? When I turn it on in the factorysettings and restart the system it comes up in Android settingsmenu. When I start it up I get a black screen?
When in recovery mode how to scroll in the menu?
Or does the touchscreen work in recovery mode?

Usually with the same reset button...

Sorry I can't help
Learned from another topic when you have Canbus you can't set the steering wheel keys

And do you have your radio antenna Installed?
For going into recovery:
Press reseat button until you see flashing the button lights..(approx 25sec)
Release and press again until see your nougat logo.
Release and wait for recovery menu

Hi, can't get into recovery.
Do I have to press reset button when unit is off or on?
Took power cable off, pressed reset button, put power cable on and followed your instructions. Did not work.
Please advise.
Solved:
First in the systemmenu there was no way to activate developer settings in the normal way. Solved this with Total Commander.
Bought a USB cable, in my case A to A. Couldn't get in because USB standard is set on 'Host' and it is not possible to connect with a OTG cable.
In factorysettings wrote 'abdon' and immediately the headunit came up on the with USB connected Windows PC .
On PC choose to see the files. It works!
Downloaded latest SDK. Opened commandprompt and changed dir to the SDK directory.
Put in command: 'adb devices' (without the quotes) and there it was!!
The command that worked for me to get into recovery is: 'adb reboot recovery'
Only problem left: fastboot is not working in recovery mode. I think the problem is that the USBconnection goes back in Hostmode when booting into recovery. Anyone now how to solve this?
Hi guys, first post here.
I recently purchased a Witson V5754 unit for my Astra J which is an Android 8.0 PX5 unit with no external buttons. Everything is controlled by touchscreen or the factory panel buttons and steering wheel controls.
The unit was working perfectly but froze up and couldn't get any response from it. When I switched off the ignition, and then switched it back on again, it came back with the same frozen screen. So, I pulled the radio fuse to cut the power to the unit. On re-inserting the fuse, the unit powers on with the initial multi-media nav splash screen, then followed by a black screen for about 5 seconds before going into a recovery screen saying that it can't load android and my data might be corrupt.
This screen gives me 2 options - try again or factory data reset. The problem is, with no external buttons, I can't move the highlight to choose anything on that screen!
Any ideas, guys and gals?
PS - I would upload a pic of exactly what it says on the screen but due to forum restrictions in my first posts, it won't allow me to attach the pic

If you have a reset button (a small hole that could.be pressed helped by a needle) use it for moving between options (short press = move. Long press = accept the chosen option)

Hi, have you solved the problem? I have a similar problem with my full touch px5 and I have not found any reset buttons from the unit or the screen.. So now I can't get out from recovery mode. Reversing camera works tho.

That Unit (Witson V5754 unit for my Astra J) has no hardware reset button !!!
The hole right next to the SD slot is fake.
Only solution is to open the display part and solder a button to key2 + gnd.
I know, because I have that unit myself and tried all the buttons + combinations, no sauce.
EDIT: Search in my posts or in the hardware section for more info
Thanks, will try it soon. I have Witson V5637, but I think the HW is the same.

I have the exact same board under the screen, but I couldn't get it to work. Tried with key2, key1 and rst, all with ground. The idea is to get the key2 to ground with the button? When I powered the unit the key2 didn't got any voltages so if it is activated with ground, it is not obviously working.

Please find my posts about it.
You need to wire LED1 or 2 .. cant recall, because it functions as indicator.
What the key on single press does is MUTE
Long press powers off the screen and keeping pressed the HU goes to sleep or even longer pressed, reboots.
The indicator starts lighting up when pressed long enough for reboot and start flickering after, where you start to release-push until you are in recovery.
-> Since the mid-long press shuts off the screen, it could happen, that your screen stays black -> press again to power on the screen.
EDIT: Yes, key+gnd does it.
You can even map this new keys in the keystudy app now, because they're resistive.

Didn't work with this wiring: key 2 (or key 1 or rst, tried them all) -> switch pin 1, gnd -> switch pin 2. So when the switch is pressed, the key is directed straight to gnd. Should I do something differently? I don't need any indicators, just need to get out of recovery mode.
I have checked the posts in different thread you mentioned, but they are as jibberish as other answers
Most ppl try to even enter recovery for that, the indicator helps a lot.
If you are in recovery already and need to get out, key2 long press should activate the highlighted entry. This is also mentioned in the top lines in recovery.
key2 pulled to gnd will do. Assuming you use the gnd provided by that connector.
Yes, the gnd was from the same flex connector slot. Checked with a multimeter that it is also a shared ground and the switch was properly wired. Still not working with the switch.
Lyckily I got an usb keyboard. I plugged it directly to usb1-port at the back of the HU while powered up -> didn't work. Then I left it plugged and powered the unit completely off (not even power to memory) and on again -> the keyboard starts to work and arrows/enter key did the trick!
Thanks for your support although it didn't solve my case (which is strange because of the same HW).
is there any way to use the recovery without rst button?
At the outset, I'm sorry for digging up the old topic, but I can't cope with my device at all. After connecting to the power, the device displays the Android 10 logo for a second and then the screen is black. I need to enter recovery mode, but like the user above, my device does not have a reset button or any other physical buttons. After disassembling the device on the board, behind the display, I found pins as in the picture, ie RST, RST1, GND1, GND2. After shorting the RST and GND1 pins, you can see that the device is restarting, which I suspect is like a reset button (?). I will be grateful for any help on how to enter this recovery mode.

For MTCD/E, I've posted some hardware methods for entering recovery.
