Hi,

Thank you for your thread.

I am assuming this tutorial won't apply if I already erased my modemst without taking a backup? Because if I were to backup anything now it would just be an empty file?
[OnePlus 2 Q&A, Help & Troubleshooting] Tunatje:
So sorry to hear that. Indeed, you will have a empty file.. You never made a Nandroid backup? If not, this is a hard lesson you have learned to read always the threads about flashing stuff for the first time. It's always mentioned that you have to make sure you have a full Nandroid backup.

Hi,

You can't edit a IMEI. At least, not that I'm aware of. I've read that people used a HEX editor but not sure how that works or how much time that costs.

My thread is only for people with a modemst1.bin/modemst2.bin backup made through terminal..

However, there is a new guide for people without a backup, but think it's applicable if you haven't used the "erase" command.

[MTCD  Android Head Units Q&A] mddsd:
Hello,

I recently got a Android Head Unit for my Citroen C4 2012 and it's a MTCD_MX.

I have some issues with date/time always resetting to 01-01-2012 00:00 after turning off the car and waiting a few minutes.

If I start car the within e.g. a minute or so both date and time are intact and correct, but if I wait more than minute to start the car, it reset to 01-01-2012 00:00...

Also I've tried to change the date and time settings in system settings by turning off the automatic date and time and automatic time zone.

But it makes no difference. I should say that if I keep the automatic settings as ON, the Head unit will retrieve time and date a lot quicker from the wifi-network in my car...

Also on another note I'm not able to save any radio stations, they are also being reset to default, and same above, if I start the car within a minute or so they are intact...

Is this something anyone can relate to and perhaps have suggestions on how fix this...?

I got a firmware update from the buyer but as many others here I'm not seeing it being applied.

I put the two firmware files on a sd card and the Head restarts by applying the update, but all dates and version numbers are the as before the update.

Perhaps I need to change the of the two files... Anyways any help regarding issues with date/time and radio stations are very much appreciated.

Here's my version info:

[MTCD  Android Head Units Q&A] kufu:
Hello,

From what I can tell, you have a problem with the wire connection. There is an always on wire and a wire that is working only when contact on. Check the connection plug. Better go to a specialized service.

Good luck!
[MTCD  Android Head Units Q&A] mddsd:
Hi Kufu,

many thanks for the info. :)

My guess is that perhaps the two connectors from the main cable is in the wrong place in the head unit (see image below with number 1 and 2).

Perhaps I should try and switch places with these two connectors, what do you think?

Are there any chance of me short circuiting the head unit by doing this?

Below is a picture of the backend of the head unit with two connectors marked 1 and 2.

[IMG="Backend of the head unit"]http://www.dsd.se/BackEndMainUnitDescription.jpg[/IMG]

Also there are no wheelkeys available in the settings menu but some of them work anyways, perhaps this could be related to the same issue?

Besides the two connectors from the main cable, there aren't a lot of cables I can connect wrong...

Many thanks.
[MTCD  Android Head Units Q&A] kufu:
Hello,

DO NOT switch those two connectors as you shown in the picture. One connector is for power supply, illumination, etc. and the other one is for the speakers. You should have a diagram on the unit. Again, DO NOT try to switch those two connector, you CAN damage the unit. One connector is power input, the other one is speaker output.

As I said before, on the POWER connector, there are 2 cables with (+) from the battery. One that is always on, the other only when contact is on. Sometimes those two wires must be switched in the connector. If you do not know how to identify them, go to a specialist. Is not big deal but if done wrong you can damage the unit.

Best Regards,

Kufu
[MTCD  Android Head Units Q&A] mddsd:
Thanks Kufu :)

I've asked the seller about the "always on power", if this could be the issue.

The head unit should be for my make and model, which is Citroen C4 2012, it feels a bit strange to switch the wires in the connector.

I really do not think I should have to do this...

I'll keep you posted about the development.
[MTCD  Android Head Units Q&A] metinb:
Hi,

I have the same exact problem, according to picture I have the same unit as yours. The only difference is the car model mine is Peugeot 508 2012.

I have been in contact with my local dealer since the first day about this. They've replaced the unit, replaced CANBUS, replaced connections so far nothing. Yest he erday, my dealer replace the unit and the canbus,. Same again, does not save time or the radio presets. Now I have another issue, I lost the front parking sensors as well.

I wanted to flash the ROM with one of the custom ROMs but in my case, it's not an option because it's an in dash without panel. There is no way to get in or control recovery menu.

Did you find any solution?

Thanks
[MTCD  Android Head Units Q&A] mddsd:
Hi,

according to the company I purchased the unit from, the solution according to them is to connect a second power connector that gives the unit low power and this should keep date/time and the saved radio stations...

I'm not buying this since the unit is sold as 100% supported by my make and model and all other connectors are 100% compatible. My own solution to the date/time issue was to use a 3G USB dongle that was fast enough to connect to the Internet and the date/time settings are set to get date/time from the network. This now works great since the unit has working Internet before bootup...

But the unit is not without issues, it seems that the manufacturer Witson (in my case) have left a few software issues that really need to be corrected. So I've sent a few emails to the manufacturer (with the permission of the official reseller). I'm waiting to hear back from Witson.
[MTCD  Android Head Units Q&A] metinb:
Hi,

Finally, I sorted the loosing radio preset issue. It turns out there are two power cables on the car's original connector. Both of them are alive when the main switch is off. However, one of them cuts off when car goes into economy mode. That' was the one android head units was connected to. All I need to do is to switch the power cable on the supplied connector. which came with the head unit. Now, I do not loose any radio presets and GPS stays connected - No waiting time to connect after each boot. :).

Hope this would be the same case for your make.

However I still have issues with the CanBus decoder.

So far, I tried two.

1) Bagoo (PSA) > all parking sensors are working. buttons on dashboard are well configured but cannot say the same for SW. Cannot answer the phone, and all right side buttons are operating to switch between open apps or change source). There is no door open warning and On dashboard monochrome screen radio displays as off so there is no feedback from CanBUS to car.

2) Simple (PSA 408) > Only rear parking sensors are working. all most all dashboard buttons does the same operation and it's not possible to turn off the radio. On the other hand displays if door(s) is open, can see the radio status on dashboard monochrome screen but only source type. Does not display any info about playing radio station or track number. It's also possible to configure Car configuration and memorized speeds for cruise control.

I decided to keep Bagoo because did not want to loose front parking sensors and more comfortable with all dashboard buttons. But it still annoys me I have to answer the phone only from screen or phone itself.

Which canbus are you using?

Thanks

Metin
[MTCD  Android Head Units Q&A] mddsd:
That's good news :)

Not being able to save the radio stations are annoying.

The GPS takes a while to get a position so if that will speed things up as well, that's great.

I'm bit confused as to which cables I need to switch?

Are they on the connectors that came with the head unit, if so which ones?

I currently using PSA Bagoo, I've tried quite a few different Canbus settings but this is the best one I could find, although it's far from complete and working...

A handful of buttons are working, although all buttons for the climate control are working, it's just that the onscreen information shows the wrong temperature, it's off by 4 degrees Celsius (both on left and right side). And there is no warning or information regarding open doors etc.
[MTCD  Android Head Units Q&A] metinb:
Yes, you need to do the switch power cable on the connector came with unit. (on big black side connected to car's original).

1) With a tester you need to find out the second power source on the original car's connector.

a) First turn on the switch to make sure the car is not in the economy mode then switch off and pull out the key.

b) With the tester you need to find the location of the power cables. (you should have two)

2) Determine which of the power cable goes to unit. > Only one of the power is going to unit through big black connector. The other power cable goes to empty leg.

3) disconnected big black connector.

4) On the big black connector (came with the unit) switch the power to the place where the other power comes in.

[IMG="this is connector, you need to do the switch on"]http://image4.pushauction.com/0/0/3164140b-ba78-4efa-90be-074831d0902c/349105f4-07cb-4041-923c-520401cdec7f.jpg[/IMG]

I've been waiting to find out if LG would enable bootloader unlocking on any of the V20 models before buying one. And now they allow the US996 to bootloader unlock.

Unfortunately, the US996 is missing a bunch of bands that are available on the H990. Specifically, I'm interested in LTE bands 1, 28 and 40.

So now I'm wondering if anyone has tried unlocking bands.
