System Preferences crash

Hi !, I'm running Malaysk latest 1024x800 DualCore ROM (24th August) and everything is fine but when I try to enter into System Preferences I get a crash. Any help?

Thanks in advance.
[MTCB Android Head Units Q&A] mrbean2k:
Not sure about built-in option in the HU, however If you are using android to sync with the unit you can try to use an app called Bluetooth phonebook ,

It fixed my synchronisation problems and you have extra options like special characters and switching first and last names .

Hey everyone! First off, im new to the HU part of android but im skilled with Android itself. Now that being said, i've caught up with the MCU & ANDROID part of a HU so im not completely going at this blind.

I recently bought a HU with android 4.4, a RK3066 board, and a 1024X600 display that is found online as a Hotaudio HU (http://xdaforums.com/android-auto/android-head-units/hotaudio-model-2100-2din-7-1024x600-t3188081) <-- thread i found with the same HU.

Point is, it was working perfectly for a month without a single hicup, until today.. THE DAMN THING WON'T BOOT!! It shows the Android boot screen, then goes into the car logo... The logo shines like normal but it just stays there forever! I've hit the little reset pin a 100 times but nothing. Tried combinations of reset and power, reset and back, reset and vol-down/up. But nothing. I loaded up the proper update.img in a FAT32 formated sdcard and turned on the HU but nothing different happens. Just forever stays on the car logo.

Any help would be appreciated as I am now driving my 97 Toyota Supra with a Toyota logo for a radio.

Do you have the automatic screen dimming activated? I had a problem a long time ago where it had turned off the backlight all the way. If you shine a flashlight real close to the screen, you can see the menu and change the brightness.
[MTCB Android Head Units Q&A] ImitableBeatle:
Like I said, it clearly shows the Toyota logo after the initial Android 4.4 kitkat screen and then just gets stuck in the shining Toyota logo.
[MTCB Android Head Units Q&A] SkyBehind:
You probably already tried but for me it's reset and power at the same time, the let off reset and keep power pressed.

You can also disconnect the battery and wait a min or two before plugging it back in.

Frozen KGL-753

Hi all,

I bought a KGL-753 from Kai Ge Le through their Ebay shop about a year ago after being in contact with Keylo Lou and Dana Tong.

It was working fine for 10 months, but recently it always freeze on boot up. I first see the Android logo when I power on, then come to the "BMW logo" screen and it freezes.

It's unresponsive and I can't switch it off.

I can reset with paper clip, but it will just reboot and freeze at the same screen.

I also tried disconnecting the power, but it still freezes.

Does anyone have troubleshooting tips?

Thanks!

Need your help

Good Day Gents (Ladies?),

I messed up... Bricked my system - black screen, no recovery boot. My system is a hui fei/KGL. I know what original mcu and android image i had, I have downloaded them.

My unit does not have the OTG USB in the front like most of your units seem to. I have tried getting into bootloader mode using the rear USB ports (I thought maybe since there is no front, they used OTG nest for rear) - no luck. I would try the shorting of pins on the chip but is there any point of it without being able to connect to it via USB?

Has anyone run into this with a unit similar to mine? I can post pictures of the unit if anyone cares/for anyone that may come across this in future.

As you can see it has buttons on the front (reset button is behind the GPS SD Card cover), but no USB.

I have taken it all apart to see if maybe there is a mini USB port somewhere on the inside they used for programming but did not find it. I did find a connector for a ribbon cable that wasn't used which had "24P-USB" written next to it with lines pointing to two of the pins (I can attach a picture if anyone cares). Is there a way I could rig a usb module to the pcb myself?

Any help is much appreciated!:)

[MTCB Android Head Units Q&A] Pyotr_Bagration:
Yes, I tried putting MCU and Update on GPS Card, tried restarting it a few times, in the different ways I read about. I gave it about 10 minutes before trying something new - should be enough time for it to update right?

I do not get ANY image on the screen. just black. If I hold power and/or reset for duration of time it flickers, that is the most response I get from the unit. The hard buttons do not get backlight, the rear USB has no power.
[MTCB Android Head Units Q&A] TiBiSMART:
you have to use the front USB for recovery.

Thank you for reply, I have looked through that already. Issue is I have no front USB.

It's possible the KYD base didn't include Superuser, or they disabled the functionality (but left the password).

[MTCB Android Head Units Q&A] ImitableBeatle:
I've tried that 101 times. Doesn't do anything differently it just keeps getting stuck on the car logo. Doesn't freeze it just keeps shining.
[MTCB Android Head Units Q&A] vdubskey:
I have this same unit, well had, I sent it back and currently waiting for the new unit to get here. I also had problems with my unit. It would randomly shut off. This unit is very similar to the Joying units that also have Capacitive buttons and no USB port. Hardware and software wise.

You can try to get it into recovery by using just the reset button. There is a video on YouTube of the process on an 8" Joying model with no USB port or physical buttons. You press the reset button to get the unit to reboot and immediately press again and hold it until the button's flash. Release the reset button. Single press moves through the menus and long press to select. I was able to get into the OS to update so I haven't tested this method personally but seems like its your best bet.
[MTCB Android Head Units Q&A] ImitableBeatle:
Holding the reset button just keeps it powered off. I tried but didn't work. I've tried the reset and held each button individually and still nothing.
[MTCB Android Head Units Q&A] OneCheekyDevil:
I have the exact same unit and it's how i get myself into recovery when i boot-loop (which is what you're suffering atm).

The only other thing i can think of is maybe cutting the power to the HU (hopefully via a fuse) for a few minutes and then returning power to the HU. I'm hoping it'll take you to recovery first (if my memory serves me well of when i first installed the HU in my car).
[MTCB Android Head Units Q&A] jrgalang:
Experiencing the following issues and hope to get guidance from the people here:

1) Radio signal is weak - I've already opened up the unit and checked the grounding of the antenna wire. Solder and copper wire is connected and intact, but as shared through the links in the first post, I went ahead and taped it anyway for good measure. This improved reception a bit but there's still too much static going on and I'm still not getting the same radio reception as I have had on my WinCE HU. I feel as if my Android unit is still not giving power to my antenna which is boosted stock. So... given such and without replacing the IC - is it safe and worth re-wiring the antenna's positive terminal to my ACC line? The reason I'd like to test the theory is because even if the antenna is connected, if simply nudge or reposition the angle of the HU while the car is stationary, the FM signal also gets affected.. BUT I'd prefer getting some sense of assurance at least before disassembling the unit again from the vehicle

2) Touch panel issues - after I inspected the radio and re-assembled the HU plus a couple of drives out of thought, my display suddenly experienced ghost touches at the bottom-left side of the screen on my last drive. I have had to restart the unit several times before the ghost touches stopped, and when it did stop, I encountered a new issue: I'm finding it difficult to accurately press any letter in the middle row of the keyboard / screen. Say I want to key in the letter "a", it keys in either Q, SHIFT, or Z instead. I've been Googling but haven't found any app that may help me solve the issue... so if someone can recommend a software-approach to resolve, please advise as I'd really prefer that route versus hardware replacement. IF, however, there's no amount of software fixing that can help resolve this - can anyone recommend a good store for purchasing replacement parts? I'm wondering if the touch panel / digitizer is universal across models, or at least universal across KGL4 MCU's.

3) Bluetooth keyboard pairing - is this possible? With the issue above I tried to pair my mobile Bluetooth keyboard, but nothing happens after I click on the device name in the Bluetooth menu and click [Yes] on the connect prompt.

4) RK3066 to RK3188. I checked the link from the first post but it simply shared that someone's going to upgrade their CPU. I haven't found the link to a supplier that actually sells the upgrade piece though. Can anyone share a link to this too?

Minor Issues

I haven't seen this one come up.

Just installed a wireless reverse camera on my unit. I Seem to get signal during boot (before Android has a chance to boot) and camera shows up. But as soon as I get into Android and try to put my car into reverse again I get a red "no Signal!".

This seems kind of odd as I can see that the wireless receiver is on. Same with the transmitter. Could this be MCU related?

I might try to run a long RCA cable to the back of the car to see if that makes any difference.

Any body tried installing one of their unit as well?

I'm Running Malay's Latest ROM RK3188 800*600 ROM btw.

Another Issue that I am experiencing is that MTCservice no longer controls spotify nor any other 3rd party app. It was working really well before so I don't know what caused it to stop. All the other settings are working fine (Auto volume, Auto startup music player etc....).

Let me know if theres a fix for this =) Thanks.

[MTCB Android Head Units Q&A] agentdr8:
Which brightness control app/method are you using? There's at least 3 or 4 different ones that come with Malaysk roms, not including apps on the Play store.

Did you try messing with the volume setting in Poweramp's screen full of knobs? Do you get sound from other Android apps?

You can't normally take a decompiled app, add a few lines of code, and recompile it. Having the reversed java code gives you insight into how the app was originally designed.

If you want to write straight java mods or patches for an app, you can use DexPatcher. You could also achieve the same with an Xposed module.

Hi Nixfu

I have a Joying 16gb quadcore 1024 x 600 and I have no issues with the Malaysk ROMs, the only issue I have had is with the modded MTC Bluetooth APK not working, modded radio and music are not a problem. If you want to add the bluetooth just save a copy of the original somewhere so that you can revert back if you have any issues.

[MTCB Android Head Units Q&A] ImitableBeatle:
Alright so after some testing I was able to find a way to get into the recovery for the HotAudio 2100 unit.

1. Take off the top of the HU.

2. Look for the little C17 connector in the upper middle of the board. (Picture attached below)

3. With metal tweezers, short circuit the connector from both sides until it restarts completely then let go.

4. Once in recovery, to move down the list make a quick short circuit on the C17 connector. To select, short circuit it for about 2 seconds. **Not too long or you'll restart the HU**

Using this method I installed the latest ROM from Malaysk and fixed my HU! :D

***This should be posted somewhere for future reference.
[MTCB Android Head Units Q&A] sabruri1:
Thank you so much!
[MTCB Android Head Units Q&A] agentdr8:
That is good info to have. Might make sense while you have it open to add a momentary push button to those C17 pads in case you need to get into recovery at a future date. This might also be the same info that others here had discovered when trying to add a physical power button to units that have none.

I'd go through Poweramp settings then. See if enabling/disabling some of the sound options makes a difference.
