[Android Head-Units] Need4Camaro:
Thank you, I understand now. So the data is stored on the internal cache and thats the actual app itself. Normally it cannot be moved to external storage asside from a feature called APPS2SD which only some Androids have (and Im assuming these are the ones that you see 16GB / 32GB storage and cannot see the internal cache). Now when you swap the SDCard with external2internal it is swapping the external SD with the internal SD, which is basically not storing the app but the cache and user data of the app.

Now I have a new question. When you partition the external SD for apps2SD you have to make a ext2, ext3 or ext4 partition, and a FAT32 partition. From my understanding the ext# partition holds everything the data folder holds., the FAT32 partition holds all of the app's user files.. so for example tomtom maps, the apk itself would be installed on the ext# partition, and the actual map files would be installed on the FAT32 partition. I noticed there was another partition called swap, is that necessary in any way? Also the mount structure for our units is different than a standard phone because our External SD is stored in the mnt/storage/extsd1 << or something like that. I

So with App2SD ... I would have to first make the ext# partition to install apps on, simulating the cache storage so Android can read it. Then I would have to find where the remaining storage for my FAT32 partition is being stored and swap it with external2internal so I would get this storage instead of my internal SD...

What if I just formatted the entire SD as ext# - I would lose capability of adding files to it with Windows but will it still beable to hold documents, photos, ecton the INTERNAL memory? or will that just go to my internal SD automatically?

Hey, do you know if there's a way to set the battery default level to something different than 0%? Some apps (Igo Nextgen for example) check the battery and throw some alarms because of the "0%"battery they are detecting.
[Android Head-Units] perieanuo:
Hello Sir,

The right way to handle Igo is to search in the ini file for a line that disable battery checking.back in the old days when I did gps instalations Found that Igo have a lot of parametrable options,I'm sure you can dig for this on google.

Odd thing,I had Igo at begining,it didn't say anything about battery,maybe you'll have to declare the device in igo ini file not as phone

Good luck

Sys.txt is the ini file for igo i hope it is correct

You're not going to believe this but my head unit completely died. I went out to begin downloading apps and noticed only two of my buttons were working. The CD ejection key made the volume go down, and the menu button made it go up. No other buttons worked or did anything. I decided to try to update the MCU so when I put it on my flash drive and came back to my car, the HU would not boot at all. Infact all the button illuminators were dead like it wasnt even receiving power. I pulled it out and rotated it and noticed once in awhile I could get the buttons to illuminate but not long enough to power it on, I messed with the ribbon cables, made sure they were tight, touching them had no effect on the unit. Made sure it was plugged into power, disconnected it from power and reconnected it, nothing. I gave up and put the unit back in. Now the unit's buttons illuminate for 8 seconds, flash off for 1 second, then illuminate for 8 seconds, flash off for 1 second, and repeats...Im thinking its dead....

:(

Try to put original firmware on sdcard and use the upgrade procedure(press reset and poweron). What did you do to the unit? Did you played with android partitions? Please bot that these are Chinese "quality" units.
[Android Head-Units] Need4Camaro:
No. did not get that far this time I'm afraid I simply went to turn it on and then that's what happen

[MENTION=6863837]Need4Camaro[/MENTION] can you try to open the unit, check and move/fix all the cables: from front fascia module to mainboard and from dvd to mainboard. The symptoms you described may be related to bad connectivity.

Hi, lets start by saying that im very noob with all of this stuff, just a couple of rooted phones and so on behind me..

But I REALLY need some help here, been stuck with this for 24 hours now.

Anyway, I got one of these bad boys, an YHT-271 from aliexpress (cant post a link because under 10 posts..).

I tried rooting it, without success and now im stuck with the guide from this particular thread of rooting, the part where you click Step2, reboot and rm /data/local.prop. But the file is not found in my device. Because the rooting software was not for my device?

So, now the icons are all dark, except when you visit the AUX app, after that you can see stuff but the machine is really slow.

adb connection wirelessly works, but boot and recovery commands dont do a thing.

If i try to reset factory settings, it just runs endlessly and does not do a thing.

Tried to get a new firmware from the seller, with no luck (damn chinese.. :) )

Nevermind the rooting part, how can i get my machine usable again? Again, please help.
[Android Head-Units] dragoescu:
Ola,

If you are sure that is an AN-21 unit, flash a new firmware.

Problem solved!

I googled the system version and stumbled upon this:

xdaforums.com/android-auto/android-head-units/21-unbranded-6-2-2-din-4-4-2-car-tried-t3173762

Where i found this:

4pda.ru/forum/lofiversion/index.php?t522762.html

Google translated russian to english, found the 2.9.5 version firmware, copied to an empty micro sd -> Update system from the menu and it took forever, even after the update, the first boot was very long with a total black screen waiting at the end.

Then the radio noise came, still a black screen, but after awhile pushing some buttons i could get to the home screen, but it was the same as before: All laggy, black icons and ****.

But this time, the reset to factory settings worked and everythings fine now! :good:
[Android Head-Units] Need4Camaro:
I dont know how or why but somehow it started working again like nothing ever happened to it and is continuing to work.

I decided to play with app2sd. It seems as if apps2sd doesnt see my external SD card unless I swap the internal and external SD with internal2external... If I swap it though, then that will cause issues during boot because I dont think anything will beable to mount before external2internal swaps the internal and external SD.
[Android Head-Units] dragoescu:
That could be the problem with apps2sd. Related to the hw, maybe when use the unit kore and the inside temperature is going up sone of the cables are more flexible and it can move. So an imperfect contact can be the problem.
[Android Head-Units] Need4Camaro:
Meh. Just dont get it easy.

I decided to play around with it some more.

There are two options in settings > General > Extra Settings to switch SD 1 and

One says switch SDcard1 and 2

the other says switch SDcard

I set them both to open, and can't see my SD card, now unlike before, my USB still mounts just fine.

So I set them both back to close.. ..but neither my internal or external SD card will mount. ES File explorer says my sd card is empty or unmounted

I performed factory reset, no effect.

I attempted to reload the firmware, but it just gives me:

"System Update Begin

System Update End"

and then I attempted to load the full format onto the SDcard and still get:

"System Update Begin

System Update End"

Im completely reformating the SD on a slow format right now hoping this helps.. Odd thing is, unlike before, my USB still mounts no issue.

GPS Question

I am having trouble with my GPS and am seeking some general, maybe specific if available, information about how it works and what I might need to do to determine if it is a hardware or configuration issue. I recently upgraded my firmware to the latest version of RedMod and my GPS worked but it was very slow to lock so I tried to make it better by doing a factory reset- and that was apparently a mistake :crying: After the reset I lost all my preinstalled software, of which i have no copy, and the GPS never even tries to search indicated by a none flashing GPS icon. I have tried using GPS Test and it says GPS On but the icon never flashes on and off as if it is not even being initialized. Hopefully someone can help me determine if the failure is hardware or configuration related. I can send any info you may need to help if you ask. I would be very thankful for any help.. :o

I got it to work again, it seems as if anytime you use apps2sd you must fully format the external sdcard as in a slow (not quick) format before the headunit will recognize it. I managed to move all my apps to the SD card and have all the storage I need now.

Do you know of any good backup programs for my Android? I dont want it to completely reinstall it apk by apk but to fully restore like a restore point in Windows with the apps I have and their current states installed in such way.

Hi guys I bought an Chinese AN21 (Mstar) and I am experience 2 issues.

RedMod 0.2 http://youtu.be/xfuJ3VkiR7M
[Android Head-Units] shock132:
Hi guys,

Is there a way to install Red Mod or another firmware without updating your MCU? My MCU is 4.3.11-1-03 and after hearing about people losing some functionality I am considering not updating my unit. Can't you just take the MCU file out of the zip and then update it? Or is it not that simple?

Thanks!
[Android Head-Units] dragoescu:
Hello,

Some of the firmwares does not have MCU. RedMod 0.1.98 is a MOD collected from firmware 2.9.5 + MCU 4.3.13.

If you have root you can check /system/etc/mcu/ (or /etc/mcu) folder. If you are lucky the MCU firmware is there. Just copy it to a backup location, perform firmware upgrade and if there are problems with the new MCU just flash the old one (from the backup).
[Android Head-Units] shock132:
So if I install RedMod, it won't mess with my DVD player or anything? And if it does, I can just flash the old MCU and return the DVD functionality back to normal, right? Will I keep RedMod if I flash my old MCU?
[Android Head-Units] dragoescu:
"RedMod 0.1.98 is a MOD collected from firmware 2.9.5 + MCU 4.3.13." - where am I saying that "if I install RedMod, it won't mess with my DVD player or anything"?

"I can just flash the old MCU and return the DVD functionality back to normal, right?" - Yes, if you have the old MCU firmware.

Maybe you can start by telling us what is MCU and firmware version.
[Android Head-Units] shock132:
My current firmware is 2.9.5 and my MCU version is 4.3.11. If I'm understanding you correctly though, RedMod is just a modification of the 2.9.5 firmware and not an entirely new firmware version. I only said about the DVD player because I've read other posts about people flashing new firmware and it corrupted the DVD players firmware in the process. I take it they installed another firmware and not a mod and that's what corrupted the DVD player.
[Android Head-Units] dragoescu:
I know that using "full format" corrupted DVD firmware, not flashing RedMod.

Boot Animation app

Does anyone know how the stock "Boot Animation" app (Kaier) is supposed to work in regards to adding new boot animations? I would need to use this on an unrooted device to replace the boot animation with my own animation.

There is an option to "Import from external storage" which opens a dialog box. But I did not manage to enter something here which is recognized to import my boot animation. I tried with "/mnt/storgage/extsd1/myaninmation.zip" and "/extsd1/myanimation.zip" (having the file myanimation.zip in the root of extsd1. I also tried to put the animation file onto sdcard - same result.

The AS button is the “Auto Store" The radio scan for the strongest frequencies and then store them. I don’t need it. I would like only to search for the next station. All radio has the search button if you press it once change the frequency; on long press it goes to the next station. Does this function exist?

[Android Head-Units] m00n61:
I recommend using the modified radio app that you can find here

Details here

It's way more powerful that the default radio app - and with many customizations. My favorite is the displaying (for a few seconds) of the radio station info when changing the stations on top of the active app.
[Android Head-Units] wanxu:
There's a folder in /System/, I think, where the animation files are. You have to put your animation there (needs root to do that), and then the app can access it. Be careful with the animations, a bad formed animation file can crash the system!

Hi everyone! This is my first post here, I am hoping someone can help me out a bit. I have had one of these android double dins in my car for a little over a year now, but there is some things I really could use some help with. I can't get steering wheel controls to work. I ordered mine from asia somewhere on eBay, the seller said they would work because it is a custom fitted model to my car. Also, literally the first day I got it the DVD drive broke. I took out the two screws like it instructed but when I put a cd in it made a click and now doesn't even sound like it is spinning. not a huge deal as I mostly run everything off of a micro sd card, but can the drive be fixed? I am also wondering how I can go about installing an app that comes up in the play store as not supported by my device. Its requirements are android 4.3 or higher. I have rooted the device with baidu root and tried market helper as well as editing the build.prop but I am having no luck. Any help with any of these issues would be really appreciated!
