HuiFei - 2 DIN Pure Android 4.2.2/4.4.2/4.4.4 RK3066/RK3188 CarStereo Radio H...

I am using Terminal Emulator and not well versed here, I must be doing it wrong.

When I type in the command "du foldername" I get a response "no such file or directory.

If I type in "foldername" I get the the response "/system/bin/sh: foldername: not found"

If I just type in "du", I get a long list of responses such as "./proc/3239/task...."

I also have a diskinfo app which shows mount points if that is helpful.

Using Root explorer, I find the same big data at two locations. (/data/data/com.slacker.radio/) and also (/data/user/0/com.slacker.radio/)

The slacker app is uninstalled at the moment but here is how Root explorers sees these two directories.

For the new location I would like to use, as long as it is on either the internal Sd (12gb in my case, or my second external SD, I will be happy.

So it could either be (/mnt/internal_sd/cache/) or (/mnt/external_sd2/cache/)

If you can straighten me out on how to use the terminal emulator, I will get the path information from there.

Here is my current attempt showing no results

I tried every option including an absolute path as well

Hey all,

I am using Malaysk's latest ROM which is working beautifully. The only small hiccup I have is with the steering wheel controls and Poweramp. I have one of my keys mapped to Play/Pause and another mapped to Next (advance to the next track). These keys work perfectly with the stock Music and Ipod apps. With PowerAmp though with each key I get 2 presses. With Malaysk previous ROM I did not have this problem and it only happens with Poweramp. I know KeiserSozeyFr's headunit app can filter out double taps but didn't want to run it because I also have the Microntek service and ExposedMTC running. What do you guys think?

Interesting that you mention this.

I've never had a problem with my GPS until the last week or two where I noticed I was getting constant "GPS Signal Invalid" warnings from Sygic. Although mine isn't a KGL like yours (I have a JY) I did install the one modified by darkleo a few weeks back which might explain why I'm having GPS issues too.

The GPS settings applet is showing lots of satellites but just not locking onto them (or maintaining a lock if it gets one).

I've just gone and reflashed the stock JY 2.59 and will keep an eye on things. I do see the same number of satellites in the GPS settings and it's locked on nicely. Could be way off though, it may be that the MCU doesn't have any affect whatsoever on the GPS.

Thanks for bringing this up. :)

EDIT: Nope, just went for a drive and lost GPS again. Time to tear the dash apart in case I loosened the GPS antenna last time I was poking about.

[MTCB Android Head Units Q&A] fareed_xtreme:
A few questions:

[Q1] I would like to know if there is a way to add boot audio? Like, I have a 15 second audio I would like it to play as the device boots up.

[Q2] Is there a way to stop device from autoplaying?

I did a quick search but the search parameters used didn't return the right results. Any suggestions?
[MTCB Android Head Units Q&A] i.draskovic:
You do not have to do that. I have already did that. Answer from Sygic was that Sygic does not support rooted devices. My device was not rooted and I have figured out that Support does not know what problem is. But problem is in our devices. No one device has hardware id (IMEI code). Ok, all of them has one, but it is same for all of devices 01234567890123, and if you pay your software and try to install it on this device, you can not do that, because 10.000 or more users can install it and use for free. That means that universal IMEI code is blocked on Sygic server, but support does not know anything about this problem.

I'm running into an issue where some apps won't see and use the microSD card because the path is not a known/standard one. Is there a trick or fix for this issue?
[MTCB Android Head Units Q&A] markcm:
I believe this is the same issue I am working on.

If you search this thread for lsd you will find about 6-10 very informative posts that explain how to bind/mount external directories to you internal directory. Although I’m having an issue getting this to work, if you search my recent posts you will find the responses form member DSA and a few others to be very informative.

A short summary of how this works (in my non-expertise terminology…)

The shell script /etc/install-recovery.sh can be edited to create a binding mount between a directory on your internal memory where you app natively wants to store files, with an external directory such as your external SD card.

Again, I’m no pro at this but I think this is what you want to achieve and is fairly common recently.
[MTCB Android Head Units Q&A] Blackwaterification:
Do you have the BN unit? If so, then you're probably out of luck. I'm trying to find a way to make ethernet work on malaysk rom and will of course report back if I find a way.
[MTCB Android Head Units Q&A] echudoba:
It looks like I have the latter case as ps | -i returns different. How would I use poweramp style?

Is there a simpler code to start dailyroads like (am start com.dailyroads.v/.????????????) or startservice. DailyRoads will start on its own, record, and go into background mode with it's own settings. Using the above code I find if I stop recording it will restart by your script. If I quit the program it restarts. There may be a time I don't want it to run.

I really like the way your dimming code works. Could you steer me where to add a line to turn on and off screenfilter and what that line would be. I may have to ask agentdr8 for the script code. Sometimes dim isn't dim enough.

FYI I am still using your install-recovery.sh from July 14. before loop optimizing and lsd wild card mods.
[MTCB Android Head Units Q&A] markcm:
Thanks DSA, I will have to try that this evening when I get home.

You are correct, the big data directory is actually about 5 directories below the (/com.slacker.radio/) so I presume I will include of the sub directories in the lsd() upto the final big data directory? Assuming the actual big data directory is called "offline" with several (let's say 3 for this example) intermediate sub directories, my lsd would look like:

lsd /data/data/com.slacker.radio/sub/sub/sub offline /mnt/internal_sd/cache/offline

No double quotes? I presume unless there are spaces or special characters I won't need the double quotes? And do I need the / at the end of (/mnt/internal_sd/cache/offline) in the lsd()

And I will make sure I have a directory created on the internal_sd as (/mnt/internal_sd/cache/offline/bar)

I'm a bit perplexed why I cant even seem to get a binding on my (.../test) directories to work; hopefully once I get past my hang up it will be clear as day.

When I finally get this right, I'm still not sure what to expect to see from a Root Explorer perspective to know that it is working? Please validate my assumptions:

When browsing to: (/data/data/com.slacker.radio/sub/sub/sub/offline), although the data actually should reside on the internal_sd, what should I see at this location? Will it appear as if the big data is really here, or will I be redirected to (/mnt/internal_sd/cache/offline/)

Since I will be setting this up before installing slacker, I presume that if it works, when I browse to (/mnt/internal_sd/cache/offline/) it should only have a single directly of (.../bar) until I install and then I should see the big data written here once I install and download music for offline playback?

On million thanks for you patience helping, I really do appreciate it and hope that eventually others will be able to make use of Slacker Radio too.

I'm thinking more of storage, where the app doesn't list the microSD as a storage option in their settings (namely Nokia HERE and doubletwist). I've noticed my phone does list its microSD as a storage option in those apps and it's path to the microSD card is /storage/external_SD... should I simply bind /storage/external_SD (a known working path) to /mnt/external_sd (head unit's path to microSD) using the lsd command?

Screen Filter is used in XposedMTC by agentdr8 to provide even a dimmer screen. He has the option in his code to use it in addition to the dimmer. link to screen filter: http://repo.xposed.info/module/com.tonymanou.screenfilter

I wasn't asking you to add it to your code but tell me where to place it in your code to come on and off with the dimmer. I still need to find out what the command is. I have screen filter running on mine now and can manual turn it on and off.
[MTCB Android Head Units Q&A] Blackwaterification:
Honestly where do people buy unlocked modems? I need one that can work as either 3g for the unit or rather as ethernet if possible. I can only find sim locked ones with their firmware that makes them impossible to unlock and use with another sim. I currently have a E392 from huawei which refuses to work due to the sim being from another vendor. I live in Denmark and it seems to be the same for Germany and the UK as well where they're locked to vodaphone, 3 and so on. The modems on here are no longer sold by the companies that offer mobile broadbands which makes it even harder to figure out.

Does anybody know if the Huawei E-3276 or Huawei E-3531 work with these? They're probably simlocked, but from the company I currently have a sim from hence the only ones I might be able to acquire. It'd be the only way for me to begin using internet on my unit as the WiFi works a maximum of 5% of the time.
[MTCB Android Head Units Q&A] markcm:
Others may comment, I'm definitely not an authority on this topic but I suspect you are on the right path. I also suspect you might want to narrow the scope rather than binding a complete SD card to your internal memory.

Generally speaking, each app which stores large amounts of data, the directory with the large amount can be found. This would be the specific directory you would want to bind. You would also likely want to create a directory on the external SD rather than just trying to use the root of the SD.

There are quite a few posts on this in the past week, DSA3810 has provided some very clear guidelines in the past week.

Depending on your MCU and/or ROM, you may need to update. Also, the install-recovery.sh file needs to be current (DSA3810 has been updating the file). The current technique to avoid loosing root when editing install-recovery.sh is a call in install-recovery.sh to a file called install-recovery-2.sh. This is built into Malaysk's latest ROM's if your unit is compatible with them.

[MTCB Android Head Units Q&A] markcm:
DSA,

How do I confirm that my /etc/install-recovery-2.sh/ is executable? Maybe that is the issue, I don't even know if this is being run. I did check etc/install-recovery.sh and I see a lot of commented out text and at the bottom a line that appears to call the /install-recovery-2.sh file. But ultimately, how do I now for sure it is getting executed?
[MTCB Android Head Units Q&A] jperezch:
That´s because coudus rom is old and doesn´t include an option to activate sleep mode.

You should upgrade to a newer rom version.

Not booting...

So, I had a unit working perfectly fine for a couple of weeks and and... it just stopped working. Turned on the car on a really hot day and .. nothing. Does not boot anymore. I press power button - nothing. The unit is dark and silent. No response.

So, I pressed Power+reset and it pops-up the recovery screen. Rebooting does nothing. Just goes back to black screen.

Then I re-installed Malaysk ROM and an MCU (both worked previously just fine) from an SD. The installation looked OK. The last i saw was "rebooting" and ... nothing again after that.

Any ideas as to what else I could try?

Please help a newbie with GPS installation

Hello dsa8310,

I have searched and searched this thread, and I can not find a complete How-to instruction for installing iGo Primo and/or TomTom. Everything I search is scattered all over this huge thread, and is not complete. Instead the info is partial (probably because it "assumes" you have done everything else already).

I just want to know how and where to install it on my KLD unit (RK3066 / 6.2 inch screen / 800x480 resolution / KK 4.4.4_02022015). I just want it to work properly on the dedicated GPS sd slot (without bricking my unit).

-Where do I locate all the needed files (app, maps, poi, any needed mods)?

-Do I need to root first?

-What setting and/or modifications are needed?

I'm not a complete newbie, I have rooted and installed several modification on android phones. However, these Android car units are a different animal.

Can you please, please, please help me. Or point me to the right location, where I can find the info/how-to. I can take it from there.

I have googled, youtubed, facebooked, and xda'd trying to find this info.

Maybe this specific GPS function should be a separate sticky or pinned thread (or sticky within a stick - if you know what I mean).

Any help will be greatly appreciated. I just want the complete info (no skipping or gaps in instructions). This way I can do it myself without bricking my unit.

I don't think I need to be spoon fed on this, as I can't imagine it is that difficult (in my opinion - but maybe I'm wrong..., who knows).

Thanks,

Hello,

The first page of this thread explains most of what you are asking.

There are two main components of these headunits, the MCU which is the microprocessor, and the ROM which is the android operating system.

There are several main suppliers of these headunits, yours is from KDL. Your MCU firmware is currently version 2.55 which is fairly recent. If you want to upgrade the MCU, you will need a firmware which starts with "KDL2".

You will find many of the files posted on Google drive

here

If you want a newer ROM (aka: Android operating system), there are several members who have been creating these and sharing them with the community for free; if you use one, be sure to thank the author for their contributions... The ROM's depend on two main criteria which are: Processor (which are currently either RK3066, or RK 3188), and your screen resolution which is currently either 800x480 or 1028x 600. The most current and popular ROM on this forum right now is written by member Malaysk, see his contributions for RK3188 processors at this post #12067

Hello, Huawei E3276 works with Malaysk's rom.

I have a Huawei E3276s-150. First I'd accidentally updated it with the HiLink firmware (22.470.13.00.00), but I've found a post where people said if I navigate to 192.168.1.1/html/switchProjectMode.html I can switch it back to normal mode. (You may have to try the URL a few times, if it doesn't work for the first attempt.) In normal mode I was able to flash the 21.491.03.00.00 firmware. I think it might be a solution for people with E3276 HiLink modems. Then I'd set modem only mode with AT commands, using Tera Term. (Check this out for modem only: http://superuser.com/questions/586049/how-to-force-a-huawei-e3276-lte-modem-to-only-mount-as-a-modem)

Hello and thanks for reply markcm, but I stay more confused now.

My MCU is MTCB-KLD2-V2.51, and you're saying that I can put KDL2?

I can just load the ROM pre rooted without flash the MCU, or it is better to update both?

I just want the android rooted to be able to use other OBD2 standard, and of course have android rooted.

You can tell me the best ROM for my radio to be able to have Android rooted?
