Help!! just got an Xda IIs - seems locked up

Hi all, I have just got a Blue Angel Xda which is in mint condition but when powered up hangs with an unlit screen showing the O2 logo and some faint red writing near the bottom right of the screen which I cant read. It does nothing from this point.
I have tried pressing the key combination to enter bootloader mode and this appears to work with a blank white screen saying 'serial' and a version number - but what to do from there?
Can I reflash the software? does this problem sound easy to fix or is it destined for the bin? I have the docking cradle and some software with it - I would like to unlock it if possible but since I cannot access the PDA I cannot copy the unlock file to it.
Any help would be very appreciated - what software do I need to get it working again if I can?
Thanks in advance.

oh dear I was hoping I would be told it was simple matter by now - anyway in the mean time I have tried to get the phone to connect to active sync but it will not. I have put it in boot loader mode and it says serial on the screen which changes to USB when put in the cradle - still will not connect to active sync. I can in fact read the red writing on the screen which I said I couldn't above - it seems to be various version numbers of something.
I am using XP with the latest version of active sync for XP downloaded from MS yesterday.
All I want to do is reflash this XDA - I was told it was a simple thing but so far have had no luck even connecting to it.

Hi.
Try to do a hard reset first. You can learn how by reading the following:
http://wiki.xda-developers.com/index.php?pagename=BlueAngel_WM5_For_Beginners

No luck
Thanks for that but I never see the coloured stripes - maybe its not WM5? I can clearly enter boot mode according to that guide but otherwise just have a stuck unlit O2 loading screen. The soft reset only seems to cause a momentary blanking of the screen and then back to the same O2 logo. I have tried pressing the camera and record buttons a thousand times whilst pressing soft reset but nothing different ever happens.
isn't there a way to just reflash the rom?

Yes...of course you can reflash.
Download the rom from the following thread:
http://forum.xda-developers.com/showthread.php?t=382909
Enter bootloader mode, connect your Blue Angel to the cradle and run MaUpgradeUt_noID.exe.
When the flashing is complete...hard reset your device.

Wow - thanks so much you are a genius - I followed the instructions with relative ease and my Xda lives again - I need to play on a bit with it now to learn how to use it but thanks a million.

Everything seems to be OK - WiFi seems a bit flakey with connecting but once connected behaves well - biggest annoyance by far is the fact that there is no sound at all, no matter what the format and volume the xda is mute!

Heh..you're welcome.
The 'no sound' issue could be a hardware problem. If you are sure that the software is ok and you should hear sound then the best scenario would be a replacement speaker.
I have just replaced my speaker with a spare from a qtek s200 and it's great.
BA is a great device

I am not sure the software is OK - the PDA is in mint condition it seems highly unlikely that the sound is faulty - its totally silent - wma makes no sound at all.
I wonder if there is a factory rom I could try just to be sure if its the software or hardware - I have followed links to various 'ship' roms and they seem to be dead now.
I plugged headphones in and they too are dead so it it probably isn't the speaker?
Also the camera button starts media player not the camera and I dont appear to have any access to camera functions - I think this could be a software thing perhaps a less ambitious version of WM.
As a beginner in this forum its really hard to find any actual files - there is much talk about this rom and that but where are they kept?
surely there is a stock rom that can try to be sure the hardware is ok?

Hmm..
Try this wm2003 rom(run MaUpgradeUt_noID.exe):
http://rapidshare.com/files/111121136/BA_O2UK_14000_237_11200_ShipXdaIIs.rar
Are you sure that there's a camera on your BA? Because some BA come without a camera.

Thing is when I try the stock rom I end up exactly where I started with it frozen on the boot screen - it just wont seem to allow me to do a hard reset - I reflashed the 6.11 and works fine but again no sound and the camera says it cant initialise the hardware (definately has one)
I even flashed a T Mobile stock rom and it froze exaclt y the same as the O2 rom on the boot screen and wont respond to the hard reset buttons.
When i flash the WM6.11 the hard reset works just as it should so I conclude from this that the buttons are OK
I am at a loss as to what is going on - right now I am back to 6.11 but no sound and no camera again but I cant see me living with it like this

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?

Black screen and unresponsive unit, but radio is playing

Hi,
I recently updated my rk3188 MTCB-YM from 4.4.4 to dsa’s 5.1.1 ROM. All went well with the update. After a couple of weeks, I found the ROM was starting to run quite slow and was almost unusable - except if you kept the unit on for a long time. It was like it was loading a lot of things for a long time and once that was done, it became responsive immediately instead of being delayed to button presses etc.
So I decided to boot into recovery and do a wipe all/factory reset. My unit does not have physical buttons or a gps sd card slot. None of the usual boot into recovery options work so I use an app to reboot into recovery. I started this app and chose the correct option. At the time I did this, the radio was playing. The screen went black and the stayed like that with the radio still playing. The lights on the unit are still on but nothing works - no response at all. I have turned the car off and left it off overnight. When I turn the car back on, the radio starts playing again immediately. (This would normally take a little time while it boots up, so the unit is obviously stuck). As I cannot do any of the reset/recovery options - is there anything I can do? I haven’t removed the unit to see if it is possible to short the pins as I don’t have access to a bench power supply and have limited skills. But I will try this if there are no other options. I also haven’t removed the battery terminal to cut power yet. That was going to be my next test. But wanted to see if there was any advice before I do this.
EDIT: I took the plunge and disconnected the battery, and the unit started back up again.

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:
