Busted Standby button

hi everyone
ive seen quite a few busted/malfunctioning standby button posts but none have had any proper answer other than to open the device and clear the dust.
ive done exactly that- opened up the device, blew off all the dust. but no help.
on closer inspection i realised that the legs of the standby button had actually come OFF the circuit board.
now..i could probably take it into a mobile shop and have it fixed. but i wonder if there is any software out there that could possibly simulate a Standby Button press?
this would be especially useful for flashing ROMs..

i am sorry but i can't figure out, how it should work. if it was some sort of cab and you "pressed standby" once, how would you wake up the device, you can test that with pshutxp. plus, the program would of course not be accessable when turned of or for reset. when reflashing the device, the prog would be gone anyway. if there was a remote program to control via pc, same thing, when your device is in standby, there is no pc connection, and again, no way to do it, while not being sync with AS. so the only actual access to that function is the hardware button itself, so instead of trying to substitute it, you should probably go get it fixed or order spare parts, or an entirely new device, which is probably the cheapest.

thanks for the reply
well i just need to press it once :S
to flash a new ROM
after that i can then reinstall the app (if it exists) to do any hard resets thereafter i guess......

zes, and that is the problem, in that situation, trying to start the bootloader, and also after flashing for the hard reset, you don't have any external access to the functions or to any programs on your device (since at that moment there are none, quite redundant). the one and only option to give the device the power buttons impulse, is the power button.
also i guess you're aware of the fact that upgrading your rom does not solve nor avoid your problem, you will still have no key lock, drain incredibly much standby time and once the device shuts off, you need to soft reset it to restart. if the button in physically broken, it needs to be physically repaired or your problem will not be solved.
http://mikechannon.net/PDF Manuals/HTC Blue Angel Service Manual.pdf
that is the ba's service manual, in which you can find the exact process on how to change the power button, and if you don't have spare parts, you could get inspired on how to substitute one...
also, maybe posting a photo of the damage to your button could make people who went through the same be able to advise you exactly, since all my experience in the hardware section of the ba is purely theretical.

hi tony
thanks.
after the flash i can still access the clear reg hive thing by holding record and cam button..
that should be all i need.
as for waking the phone, i can set it not to disable other buttons while on standby, so i can wake it with Call/End buttons.
and then with that, i can use s2cu to software lock the device to avoid accidental presses.
but you're right, nothing better than getting it fixed physically.
i GUESS itll just require resoldering the little switch back on, as the damage is that 2 of its pins have left the circuitboard. i dont have the tools to do a small and precise soldering job so..
ill try to take a pic too and post one later

well i dug deeper...
seems that there is a 'Enterbl.exe' thats supposed to be related to enterin the bootloader without having to do all the hardware keypresses.
I've not yet had luck with this...dont know which 'version' i need..
so perhaps to rephrase my question:
is there an alternative way to enter the bootloader mode on the blue angel?
similar to the Wizard Service Tool (which i also tried out of desperation, though all it does is blink the BA's screen)

Volume button + WiFi Problems + Touchscreen no reaction + Board computer problems

I have some questions. (Copy from the old thread)
1. I mean that i read it here, but I'm not sure. At the moment I have very often the bug, that the volume button not works. Mute works, but louder and quieter not. I don't know when it doesn't work, but after a while no function.
2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?
3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction. After a minuten the radio shows the bootlogo and have a loop. So i have start the radio new with reset or power off from the car.
4. Since a few days if i turn off the key normally all lights form the radio and display shut down. Additionally board computer shut down too after a few seconds. Now the light from the dvd tray is on and board computer too (after a lock from the car too). I dont know why but I don't know if that is so good (Battery).
All this errors are since a few days. I tried to do any settings but the problem is always here. Does anyone no about that? I think it's an app, but I don't know which one. The last chance (if I get no solutions) is to install another rom? That is really crazy, because it's only since a few days. The days before it works perfect.
I have JY 2.73 with the Malaysk Rom from September (1024).
Thanks

Update: Now i installed 2.59 JY and tried again. WiFi will always gone with no bars. So i turn off and turn on again. At the most cases it works. But the problem is here again. The same with the touchscreen crash. 3G doesn't work. always no bars.
So the previous MCU doesn't work again. Maybe a software error.

Could you please try to measure the voltage alignedto the HU while you encounter those problems? I rellay mean at the radio side (so not at the battery poles).
Such issues could be lack of voltage. If not and flashing does not solve it could be a defective unit.
Just to ensure: You flashed Firmware AND MCU? AM I right wit this assumption?
If not: Try to flash a new ROM first (probably try Malaysk ROM)
Btw: Moved to Q&A

Thx for answer. How can i measure that? Do you know which cable it is? And if the cable shows not the 12V? What can i do to fix the problem?
Sure. I have Malaysk Rom and the MCU JY 2.59.

you would have to get amulti- or vooltmeter and attach that between plus and ground pins at your HU.
If you don't know how you should eigther try to follow another way first if possible or ask someone to do it for you (it's electrics)

Thanks. I ordered a multilmeter. Maybe it's the battery. At the moment the car works really hard if I start it. The radio takes so much battery but the radio is off. So that can be the problem.

low voltage can cause many weird problems but you have to know a new battery might not solve your problem!
If you have low voltag while the engine is ruunning then you have a different problem. eighter there is a connection issue somewhere on the path the energy takes from battery and generator to the HU or your generator might have a problem. But that is open to check when we know if it really is a voltage issue.

Hi,
i'd like to give you an update for my problems. Since the last days I have the problems, that my car didn't start. Now we see, that the battery is nine years old. Now I charged the battery (tomorrow I'll get a new battery) and the first test shows WiFi works for 3 minutes. I know - that's not a lot, but I only can try if I have the new battery. 3G doesn't work - always the same. But that's not so important for now.
At the moment I don't have the volume error. I will test it, If i have a longer car drive.
The problem with the touchscreen is actually. Since a few time, after few minutes the touchscreen is bricked and I see the points that i touch it, but I can't click anything. If I touch ten times, twenty times or often then radio shut down and shows the boot logo... forever... it doesn't boot again. So I have to make a hard reset.
And the last point with the light board computer and the light dvd slot after plug off the key is actually too. It don't shutdown the lights on the standby time from 10 minutes (set it to 10 minutes). I know now, that I can shutdown it completely if I press the volume button for 3 seconds. Than it's turn off. So it's a setting problem from the firmware?
Today I plug in the key - nothing. Radio doesn't start. So I looked behind the radio and saw, that one thin cable is not in the wiring harness and I can see the wires on the cable. So I tried to put it in the wiring harness again. I hope it works longer now. I wrote carjoying and ask for a new wiring harness. Maybe all problems will be fixed, If i have a new.

Hello again,
now I've got a solution for the wifi problem. I've tried to connected wifi - i Known that doesn't work only few seconds and after a few seconds it shows 0 bars on wifi... now I disconnected my 3g stick and LOOK it works... full bars, no losing connection. I connect 3g again and the same problem after a few seconds.
So th3 3g stick (E1750 from Huawei) makes some problem OR the usb cable?

Huawei E355 also not working. Same connection problems with malaysk rom MTCD
Any suggestions?

Going crazy! No way to put Malaysk ROM on head unit!

Ive tried everything I can think of and it wont work. I have two head units. My older GA5153 was almost too easy. I inserted the SD card into the GPS slot and the unit recognized it and suggested an update. A few minutes late...it was done! My new unit is a Witson that I found on AliExpress. I love the 9 inch screen and the fact that its a quad core, but the UI just isn't doing it. It remembers most things but there's little settings that revert every time you restart the unit. I want the new ROM on there but its just not happening.
The issues Im running in to currently:
Theres no Physical buttons on the unit. I should be able to use the reset as a select button but I haven't got that far yet. The problem there is every time I boot into recovery mode its just the android on his back and it says "No Command".
The unit doesn't do any type of auto update like the GA5153 did.
It almost seems as if the UI was designed to try to prevent people from upgrading. Any and all help is appreciated as Ive been at this for hours and hours with no success. Thanks guys!

Can't you use a USB keyboard?

As bad as it sounds, I didn't even think of that. One of the wiring harnesses in the back has a usb port on it. Ill have to see if itll read it when I plug it in.

The unit recognized the keyboard and it was functional while the unit was on, but it wouldn't work in the recovery menu. I'm not sure what to do anymore. All the ROM installer apps Ive tried have failed to recognize the ROM on the SD card. Its very frustrating but I will make this work.

What Witson model do you own?
Are you sure it's a MTCB HU?
Have you tried to contact the manufacturer?

I dont think your Witson unit is an MTCB HU.

PX5 stuck showing warning image, buttons unresponsive.

I just bought a PX5 unit, which seemed to be working perfectly until I finished installing it into my car and now it has become unresponsive with a black screen and a yellow rhombus with an exclamation point in the middle (unable to upload image as new user).
If I turn off the ignition, it will turn the stereo off and the android screen briefly shows before going into sleep. None of the buttons are allowing me to get past the screen and in to android. The reset button seems to do nothing, android is definitely running in the background, just unsure as to why this screen will not close. Any ideas?

Hi, I think I saw a yellow rhombus with an exclamation point when I was installing my radio and rear view camera was not connected to the radio. I think that it is a warning about missing video signal when radio is displaying live feed from a rear view camera.
So, one explanation for your issue could be that the radio thinks you are reversing, and the rear view camera is not connected to the radio. If I understand it right, radio can switch to rear view camera display mode based on two conditions 1) canbus information 2) +12v trigger signal.
For the condition 2), you could check that nothing is unintentional connected to reverse detect wire. If that does not help, then you could perhaps try to disable reverse view feature in the configuration menu before installing the radio to the car and/or find a working canbus configuration settings.
Please notice that I'm a beginner with Android head units and your problem might well be something totally different!!

Thanks for your reply. Some of your post seems to relate to my issue definitely, I think it is linked to the rear view camera which is currently disconnected. However I am unable to get into any configuration options. None of the buttons/resets I try get me past the exclamation screen, I can only see android once I turn off my ignition when it tells me it is closing down. None of the various reset button combinations seem to do anything with my head unit either, can't seem to reset it properly. Its strange, I will reattach the camera tomorrow and see if that brings any joy. I don't know anything about this stuff myself but I am wondering if I did something to the head unit to brick the non-android side somehow.
Edit: Unfortunately reattaching the camera did not change anything.

Update. I have managed to find a way in to the Android side if I connect my phone via bluetooth to the stereo, it then lets me use the split screen function via the top bar menu to put the warning screen other screen to the side, however whenever I touch the screen or attempt to use the android interface, my stereo goes back to the warning screen, none of my inputs via the stereo buttons or the touch screen seem to be registering with the Android side? Very confused. I have also tried as many button combination resets I can find and I have not been able to successfully get into the recovery menu, or any change except rebooting.

Was your unit professionally installed?
Also, what did the re-seller suggest when you contacted them for support?

No the unit was not professionally installed. I am not sure how I've become stuck with the problem. I made some minor changes in factory settings but nothing I thought would of caused this. The seller is yet to respond and its been a couple of days, but I have requested the hardware reset methods for this unit or any other solutions.

Check the reverse wire on the back of the unit...if necessary disconnect it to ensure no reverse signal is received.
If your unit can boot into android normally then you will have to figure out why the reverse wire is receiving signal .
Check your connectors to avoid any of them to be loose.

Everything has been disconnected from the unit except the power cable to car and and canbus, from what I can tell nothing is loose. Unit will not boot without the canbus box whatsoever, not sure if that is meant to happen.

Yes, canbus decoder need to be connected for power up the HU. If you dont need the decoder box you need rewire the harness.

I think I am going to have to request a refund and return it. Still no reply from the reseller and I am not sure what else I can try, everything that is not needed to power it has now been removed. I can't send links or else I would update the thread with a video of the touch/physical buttons being completely unresponsive even when I manage to get to Android. The unit has definitely developed a fault and I am unable to reset it. Admittedly it could be my fault somehow as it was working for the first few boots, but unless they give me something to try I am just going to have to send it back.

Quick bump. Has anyone got any further ideas? I bought off Aliexpress so contact with the seller is slow and painful, they do not seem to understand the issue and just keep telling me to disconnect all wires and reconnect. Which has been done many times. If anyone wants to post a link to the video for me I would be happy to send them it privately.

I would start a dispute with them. I had a device that they sent with similar problems and plenty of issues, which they would not help with or would not understand. Best option is to dispute to get a new device or a full refund. Could you send the video?

Yeh I have a dispute open currently, just was hoping it would inspire the seller to actually offer up a working way of resetting the device. Had to add link below seperately as needed to be ten or most posts.

https://www.youtube.com/watch?v=ujHacKESAT8&feature=youtu.be
The stereo defaults as the warning image black screen and I can only get android up using the multiwindow button with a long press. Then the android side will not register any input and will keep trying to put the black screen to the front.

Update: I have been told by Aliexpress I can have a partial refund and keep the unit, or a full refund if I return to China. Anyone have any ideas how I would go about resetting the unit if I took the partial refund? To be honest I think my only option is to return it and get the full amount back but any ideas would be welcome! Shipping to China and awaiting a refund is going to take weeks, would rather just get it working if possible.

deano35: any progres? I have the same problem as you. This is my post from PX5 MTCD/E Head Unit Discussion Thread
" Hi , I have https://s.click.aliexpress.com/e/DtwdJIt its px5, Mtce_gs_v2.90c. Now I have a little problem with rear camera. I bought reverse camera and tried to connect it into front camera input(I was curious how it would look like) and since then its stuck on camera view. Even after disconnecting camera. Only solution was disable "prohibit reverse" in factory settings menu, but with "prohibit reverse" disabled is obviously not showing reverse camera when I gear the reverse down. Everything is shown in this video. https://photos.app.goo.gl/XbYUHApzT8qTezkq6 Thanks for any advice. "
Take a look on the video, its similar as yours.

Problem with Hizpo radio

Good morning!
I have bought a Hizpo Android radio for my Mercedes Benz Vito w639 (2012). This car haven't got steering wheel or controller for the radio, so I installed it without canbus (as the seller told me) and connecting Illumination and ACC directly to the car, bypassing the canbus.
The thing is that It started working perfectly the first day, but after some time the radio started to do really weird things, like resetting alone or getting looped on the startup showing a black screen with backlight on. Sometimes it works again for 1 day and after that starts again to fail. Anyone knows what is happening? I tried to access the recovery mode for trying a wipe, but I don't know the proper combination of buttons (this radio doesn't have physical buttons, only a reset button).
I don't know if in this forum is allowed to post the link of the website where I bought the radio, but if it's possible just tell me and I paste it.
I have a video of what happens when the radio starts to fail, but I cannot link it already to the post cuz I have less than 10 posts :crying: If you need them for helping me just tell me and I will send you a PM!
Thx for your help!! :laugh:
