Thanks for the reply. I think I did not express myself clearly enough. ;)

I meant : What was the latest version PRIOR 2.7.28, which has the Button type UI and not the 4 widget type.

2.7.28 version and prior does not give me the "unauthorized UI" message AND I can not root my T7019a (encrypted)

cheers

From what I recall we have not found a firmware with the launcher without the widgets that hasn't had to be rooted to clear the ui message as of yet.
[Android Head-Units] Cebulon48:
Hmmm, not sure anymore.

Can you recall which versions were the ones without the widgets, prior

. 28.

I'll try and see ;)

audio quality depends on MCU version, not android version, right?

because my unit comes 4.3.1 and android 2,7,22. i get it rooted and for me works fine.

but of course every improvement in sound quality are welcome.
[Android Head-Units] gamewarden3006:
I have .11 on mine and it does not give the UI message and it has the new style launcher. (without the 4 big icons)

I am not rooted either
[Android Head-Units] Cebulon48:
Hi,

I am now on dot11. No UI message.

Thanks for the help. Almost a happy camper now.

Now, which MCU version is known to support "good sound" which one's buggy?

Especially 2101 series.

Android 4.4 in the works or not?

Hi there

I have a Cusptech unit and the AN-21 U without the knobs or DVD drive.

Does anyone know if there is any plans for Android 4.4 on the AN-21 U, because I have just installed the Android 4.4 version on Cusptech unit and I have to say I am very impressed.

Any more information re Android 4.4?
[Android Head-Units] Miwer:
The list is already in my post - you need to hit the "Click to show content" button...

Please note (disclaimer!):

This is not a tutorial or a guide - it's information on what I did to completely get rid of Baidu.

This may or may not work on your device, so use of this information is at your own risk.

Before I deleted any files, I made sure to install ClockworkMod Superuser (also available at F-Droid) and used it to install a new su binary.

Baidu installs its own su binary, that doesn't work with Superuser, so I had to replace it with the one included in Superuser. First time, I did not do this, and I lost root access, and had to use Baidu to root again.

These are the files I manually deleted to cleanup after Baidu Root:

/system/bin/us

/system/usr/.uv

/system/app/BaiduRoot.apk

/system/lib/librootjni.so

/system/etc/resolv.conf

Directories I deleted:

/data/data/com.baidu.easyroot

/sdcard/baidu

I don't know if Baidu is consistent in the naming of the files, or if it would create other files, that it did not create on my unit. The list may or may not be complete.

Xtrons unit

Hi, what do you think is this the same unit?

w w w.ebay.de/itm/Android-4-1-1-Kapazitiv-Screen-Doppel-2-Din-Autoradio-NAVI-DVD-RDS-GPS-BT-WiFi-/281404411275?pt=CE_Auto_Hi_Fi_Autoradios&hash=item4185028d8b#ht_5699wt_12806

Specifications seems to be the same to me with a different faceplate. They run under the brand Xtrons so manufacturer maybe different.

I've read some bad reviews about this unit mentioning bad radio reception and bad general build quality, reliability. I'm wondering are these problems the same with the AN-21 U unit?

Does it come with ISO connectors? Ebay pictures show different connectors for that one.

Thanks
[Android Head-Units] Merlins-XDA:
It looks just like my unit that I bought from AliExpress (search for Universal-Android-Car-PC but its also one of the first links to dealers on this post) and it did not come with ISO-connectors. I bought some cables and attached to the cables that came with the unit. I see that the same dealer I bought from now have a new 6.95" unit still with DVD/CD-player. I am happy with the unit and it was not that hard to figure out the cables but I did switch place on ACC and B+ because of the color of the cables. After I corrected that the unit started with no problems.

Edit: Looked at the on on Ebay and the cables looks to be tha same but I did not get the ISO Kabelsatz oder ISO Anchluss. I had to buy the ISO Kabelsatz and add it to the "ISO Kabeln". I have also ordered th ISO C-block to connect CANBUS/Steering wheel connector.
[Android Head-Units] P.A.W.S.:
Hey guys, just joined because after many hours over a few weeks searching nothing has come up or been answered about the issues I'm having with my unit. Have a td630a which appears to be the same as an21u. Unit was running system version 2.7.4 and mcu 4.2.13-1-10-2101 as stock. Have updated to sys 2.7.28.

Problems I'm encountering are; failure to resume last function (always boots up in radio app which I understand is normal? But mine doesn't go to the last preset station it was on), clock resets to 10:30 everytime it starts, Google play says can't connect to server when trying to add account.

Had anyone had and found a resolution to these issues?
[Android Head-Units] booba5185:
It sounds like you might have it wired incorrectly, and the entire head unit loses power when you shut the car off. Makes sure that you have the 2 +12v wires run correctly. IIRC, red goes to ACC and Yellow goes to the constant +12v. The behavior you are having has both wires run to ACC.
[Android Head-Units] csabee69:
Are you satisfied overall with the unit? Same question to P.A.W.S. also because we are talking about the same Xtrons TD630A unit.

No radio problems or any other issues (I saw the resume function failure but that is something which can be solved probably)?

Skipping Firmware Updates

I notice some updates have less files than others in their archive.

I want to update my Head Unit to 2.7.35. There are TWO files in the archive.

Some of the updates that precede this one have more than two files in their archive.

I'm currently on 2.7.28 and would like to skip over .29 .31 & .32

Some updates have as many as 6 files (like 2.6.77)

Can I miss something, or even worse break something by skipping over the sequence of updates?

Thanks
[Android Head-Units] jpapadami:
I don't think it's a problem. I have skipped updates, reverted back to previous ones from the so called "fake" firmwares with no issues. My only concerns are

1. Why would someone go through the trouble to change the version on the firmwares from 4.1 to 4.2?

2. There is no change log. I am updating to the latest firmware without any indication of what has changed or any visible difference from the previous version.

It seems that we're updating just so that we know we are using the latest version, but without knowing what are the improvements (if there are any).
[Android Head-Units] MFKinSINY:
yeah, that #2 is a real bummer. we just assume latest = greatest. thank jpapadami

Hello!

I have pretty much Problems with Poweramp.

Very often Poweramp loses Sound and only a push on the Reset Button helps to solve this Problem.

With the build in Audio App the Unit words great.

So now i have the Idea to change the Stock Audio App with Poweramp by renaming the Poweramp.apk into the Name of the Original Audio apk.

Does someone try that already or is it to risky?

Regards

No Audio Music Apps.

Hi,

I have a strange error problem on my unit. No audio from Music players like PowerAMP or VLC but I get audio on the default MP3 player.

Tried reinstalling PowerAMP, clearing data and cache but does not fix the issue. Only the default MP3 player works with songs on my memory stick.

I had this issue previously and after upgrading the unit it was fixed, however it keeps happening from time to time.

Anyone had a similar issue?

Please help :good: thanks
[Android Head-Units] guano30:
Welcome to the Club!

Same Error here and i hate those stock Audio APP!

I guess i will give it a try tomorrow to change the Stock App with Poweramp by renaming it......

Problem is the MCU

Coz if you hit Reset ( small hole right over the fake SD Card slot ) the Unit reboots and Poweramp works again some time......
[Android Head-Units] kaween:
Hmm. I've had a similar issue with Rocketplayer : no sound in Rocketplayer, sound in Stockplayer.

Changing the "Sound priority" somewhere in the Unit's settings to .... "3th party" I think (not able to check this at the moment) solved this issue. Haven't tried it with Poweramp yet, call me odd but I always liked Rocketplayer more. I found no adverse effect by changing this setting : audio switch from Radio to mediaplayer to TV and the Audio-Mix in the Navi software kept working too after changing this setting.
[Android Head-Units] guano30:
Well......its not i didnt try all those settings in Tone Menu with Priority...

To me all not worked.....

Maybe i give Rocket Player a try.

Does Rocket Player resume from the Postion you switch off Car?
[Android Head-Units] kaween:
No. You have to relaunch the app. As far as play position goes, it will remember the last track that was active, but it doesn't seamlessly continu like the stock player does.
[Android Head-Units] Merlins-XDA:
I have no power antenna and the blue cable he is holding have I connected to ground on the car (not radio). I am satisfied with units. My kids didn't want to ride in the car before but now they want us to go or stay in the car even then we stopped at the beach... The radio reception is not 100% but it's better than my original Kia Cee'd radio.
[Android Head-Units] guano30:
Well i dont think its in the 3rd Party App why there are that Issues..... If its Poweramp or Rocket Player dont matter i think.

The Problem is in the MCU

Can anybody tell me whats the Name of the Stock Player in the System Directory?

I have my Car outside and its already Midnight here.

---------- Post added at 12:34 AM ---------- Previous post was at 12:19 AM ----------

Is there a Car Skin for Rocket Player available? What you use?

The Gui of Poweramp is better as far i tested Rocket Player.

You cant switch between Currten and next Album by swiping up and down.

Also no direct Way to come in the Album List, only with the back Button?

How to Root with Baidu Root

I've read every post on this thread.

Everyone claims Baidu Root is easy (one-click???)

It's in Chinese & I cannot figure this out.

The original root process no longer works & that sucks because I was comfortable with that method.

My unit is in slow mode, just updated to 2.7.35 and I have the red text "UI ....."

I NEED TO ROOT. The apk says its ENG in the file name. another LIE like the 4.2.2 ****!

Can anyone help me, I'm extremely irritated right now!!!

Thanks!
[Android Head-Units] Merlins-XDA:
I first had problem with Baidu because I pressed and installed the lower apps then all I needed was to press the large upper half to root the device. I have yet not installed Clockworkmod Superuser and removed Baidu but will do it soon. I only uninstall the apps I accidentally installed while trying to root.
[Android Head-Units] kaween:
Afaik, the stock player's called com.tw.music_....something.apk or something similar (of the top of my head).

I'm not arguing that Poweramp has more possibilities, but I just never could "connect" to the program. I found it too cumbersome and at times even puzzling to use, but that's pure personal preference. I don't even need album support, as I use a "Smart list" on my Mac to compile a random list of music based upon "last time played" and I rebuild that list once a month or so. :o

Renaming your player to that name and changing the original to "old blablabla" may well be the solution for the autoresume at reboot, haven't tested that myself yet.
[Android Head-Units] guano30:
Hi!

Yes in your suggestions of Poweramp you are right!

Many issues with that Player.

Till today they are unable to make a Skin that readable in a Car. Still that small Fonts but a superbig Cover.

Many People in at the apps Homepage asked about that feature already Years abo but nothing happend.

The only Thing i like at Poweramp is the Gui. Swipe left got get Previous and right to next Song.

Up previous Album Down next Album. Touch on the Song Title and you back in Album / Song List.

Rocket Player looks good for using it in the Car, but the Gui would need some aprovements....

Maybe that Devs listen more to their Customers, i will give it a try.

The Stock Audio App isnt that bad okay, but you only can Skip etc. by using the Softkeys. They are very small and while you drive not easy to hit. Also the Font is too small in my Opinion.

But the most worse Part is the Album / File Selction. We have a 7" big Screen and they use maybe 15% of it for Title / Album.

But Cover is 85% *lol

Anyway some later i try to replace the Stock App with Rocket Player.

I think there's a version of Baidu Root that is in English. I think it might be the one post on the first page of this thread.

Just checked and BaiduRoot_2001_EN.apk appears that it's likely english. In the root section of the first post.

And as for .35, can you check if it has an MCU that ends in 7-10-2501? I guess you need root first.
[Android Head-Units] MFKinSINY:
Thanks PsychoMcSatan, but thats where i got it from. From the repository linked to on page 1 of this thread.

It's not in english as one might expect it to be from the filename.

Audio Problem

Hello everyone,

I recently bought my player with android version 4.2.2, MCU v4.1.1-6-10-4501 and system version 2.7.29. Everything works well except the MP3 audio is not balanced on both channel. Left channel is so weak. Strangely Radio, CD Player and AUX are not having this problem. Anyone having this problem?

Thanks.
[Android Head-Units] P.A.W.S.:
Ok, I was pretty sure I had it wired the right way (not my first time at the rodeo) but I have just double checked and everything is fine with the wiring. On my unit, red is permanent power and has the inline fuse coming off the head unit pigtail, yellow is the ACC switched 12v. This setup makes sense in my head and is also the way that the wiring diagram label stuck to the top of the unit suggests. Cheers for the idea booba, was worth checking to be sure.

I am thinking it could be an mcu problem? Wondering if like in a system version update there are some things that aren't re-written in the file and they just carry over through versions untouched. Therefore, if the unit was never installed with a version of the mcu (or system for that fact) that tells it to behave in a certain way or that it has a certain ability, it doesn't know it's meant to do these things and the current/stock "version" glosses over the instruction as "assumed prior knowledge". (I hope that makes sense and everyone can follow it?). So, if I backdate the mcu version and it picks up the "knowledge" from an earlier version and then update back to the new or current stuff everything should work properly. Does this sound right to those that understand more about these units and programming than I do?

[Android Head-Units] Zaphod-Beeblebrox:
I don't know where you got this, or what device it is for (I HOPE its' for AN-21U). But it's not a flashable update.

I've just started looking through the files, but this looks to be an unencrypted version of the system/update.

***Update

Yes, it has unencrypted versions of the various system images. However, a quick search on sion electronics shows that these may not be the same devices/firmware we have in the AN-21U. Also, unless we can figure out how to encrypt/compress these images and make them flashable and/or use the recovery.img in this file to replace our recovery, it may be of limited use.

It's certainly worth exploring more, but I don't have a lot of time to dedicate to it at the moment. Maybe someone can figure out how to use the recovery img in here on our systems.

MCU version for No DVD Unit

For those who have this No DVD Android 4.1 car stereo, can you please tell me what MCU you are using or what MCU it came with? Mine came with x.x.x-1-10-2101.

I'm having some Torque Pro problems where the app spontaneously refreshes and all the gauges freeze up. Sometimes they freeze up after 15 minutes of using the Torque Pro, sometimes after 1 minute. It's getting aggravating as I have to always close the app and open it back up to get the gauges to work. I believe that after the refresh the app looses connection with my OBDLink SX adapter which I'm thinking might be a MCU issue/mismatch. Thanks in advance.

System version .35 okay?

Getting ready to go for a camping trip, but I've been noticing apps hanging or crashing (Waze especially) so I was going to upgrade to the latest and greatest to see if things improve. Currently on .29 I believe.

Has anyone put .35 through its paces? Does it have the red UI message, and if so, is there an updated APK to fix it?

If there are no responses, I'll likely install tomorrow, but if it does have issues, please let me know.

Thanks!
[Android Head-Units] MFKinSINY:
I did the .35 update (from .11) it has the red text indeed. but i havent tested it yet. i tried to use RootMyAN21 and it didnt work, left me in slow mode, also my screen is black with hollow icons. I have to open aux app and close it for screen to be normal. tried BaiduRoot but it did not take, may likely need to reflash .35 and try Baidu again but havent had the time. been running .35 for a few days now, but in crippled mode.

[Android Head-Units] m00n13:
Baidu works with 29 and 31 for sure. Haven't tried 32 but I believe the only difference between 31 and 32 is the launcher - 31 has the ugly 4 large widgets launcher. Both 31 and 32 are fake 4.2 versions.

[Android Head-Units] clipcarl:
I wouldn't bother. It just says it's 4.2.2 but it isn't really and with that version you need to deal with getting rid of the red "unauthorized" text. There is supposedly a method for getting rid of it by installing an APK in /system/app but when I tried it-- while it did remove the red text-- some other things in the radio didn't work right.

I'd just stick with 27.28 and save yourself a headache.
