Need help :)

Hello everybody,

I'm french so forgive me if I'll do any mistake.

I've followed the tutorial in the first page in order to root my head unit. Everything was fine until the moment that I need to enter the commands. Because in the video the man is using cmd on his computer, and in the tutorial is written that we should use Android terminal Emulator.

So, the problem is that my command was refused and now I have a black screen on my Head Unit. I can choose an app in the black screen but it's really disturbing.

I don't know if I was clear in my explaination but I hope that you can help me.

I can't add pictures yet cause I'm new user but I can write it.

Ok this is what I have on the screen :

@android:/ $ su

1|@android:/ $ rm /data/local.prop

Unknown id: /data/local.prop

These are my head unit informations :

CPU = Cortex-A9 dual core

RAM = DDR3 1GB

Android Version = 4.2.2

MCU = 4.3.11-7-10-650201

System = 2.9.4_20150316

Thank you.

I figured out my problem. Left front speaker clip broke from speaker, so the wires were grounding out. Also found out my right front speaker is dead so I will update the entire factory speakers with something better. thanks.

Hi all,

I have the unit on the pictures below. You can also see the current version that I am running on it. I would like to update it to the latest version that exists for this unit. What is the latest MCU/firmware that exists and works fine with this unit?

Until now, I have tried to update the unit with few different firmware versions and I managed to flash the unit but after the boot I got the following problems:

1) Red note - "UI unauthorized ...."

2) Radio buttons on the screen not working correctly and stations not being saved as presets

3) Hardware buttons on the unit not working OK

I understood that the solution to the 1st problem is replacing the com.tw.service_a5a4 file and I have managed to do it and the message disappeared. I didn't manage to solve the 2nd problem with the radio buttons so in the end I just reverted back to the original firmware (I saved the original firmware from /cache directory).

The versions that I have tried to install are:

1. 2.7.26 from the link http://xdaforums.com/showthread.php?t=2528349. I have tried all 3 "4.2.2" versions. I am getting the red message after the installation and radio buttons not working correctly.

2. Kaiser firmwares - 2.9.5 and 2.8.7. I managed to solve the red message problem but the radio is not working OK.

3. Redmod + IQ Navi 0.2.73 version - radio was not working OK.

I tried to do MCU update and when I confirmed it - nothing happened.

Thanks,

Predrag

Do not update MCU

Why shouldn't I update the MCU? Is the MCU version that I have at the moment the last for the hardware that I have or there is some other reason?

You can find the latest version on the dev's website: http://firmware-an21.wix.com/iqnavi
[Android Head-Units] lankri:
Hi,

I know this link but at this link you are not able to download the firmware.

Thanks for your help
[Android Head-Units] StuBFrost:
You need to go to http://red-mod.ru/forum
[Android Head-Units] dragoescu:
You need to help the developer via donation. After that you will receive the download link.

Wrong thread!
[Android Head-Units] Manu Berlin:
Has anyone experience/advise to increase the shutdown delay to more than 2 hours? My system is currently running on the latest RedMod/IQ Navi. But it seems like the the MCU is responsible for the shutdown delay.

Any help would be appreciated.
[Android Head-Units] Manu Berlin:
Okay, it seems like that I'm in the wrong thread. Is it might be possible to direct me in the right forum where I can find developer just for MCUs?
[Android Head-Units] Jimmy 75:
Hi everyone

After reading a lot of pages Iam not very sure wich version of Red Mod can i install in my head unit.

Currently is running Red Mod 0.1.98 and i think it works well except Bluetooth that stops after 25 minutes working...

But i would like to install another version.

My device:

Android 4.1.1

MCU 4.3.11-22-13-E50201

Kernel 3.4.5

DVD 2.13.13-1200xh

RAM DDR3 1GB

Please tellme which one stable and without bugs i can install in my HU.

Thank you in advance
[Android Head-Units] dragoescu:
I'm running the last one 0.2.94 without any issues.

Maybe you have mcu problems if bluetooth stops.
[Android Head-Units] Jimmy 75:
Thanks Dragoescu!

But i'm trying to find the version 0.2.9.4 that you recommend me and i don't know where is it.

In the fist page (File Repository, Firmware Updates,....) it is not there. I have googled "4pda.ru redmod 0.2.9.4) and obviously in russian language i'm not sure where look for it.

Please would you mind to tell me where i can download it?

Thank so much and excuse me for my inability...
[Android Head-Units] dragoescu:
I mentioned before...you have to donate to the developer and he will send you the link with the firmware.
[Android Head-Units] Manu Berlin:
You have to pay 25 USD via paypal. As soon he got it you will get the permission to open a new download area in that forum where you can access the Firmware.
[Android Head-Units] dragoescu:
25USD? I thinks this is 2 much
[Android Head-Units] Jimmy 75:
Then it is a purchase....not a donate.

I think is too much without having technical information or to the contrary it exists?...where can i watch a video or features about it?....at least to know how it works.
[Android Head-Units] petarta:
I have a device Audiosources d90-9001.

How do you install Igo nextgen ? Device ask for password for install from unknown sources! I tried 123456 and 7890 but these are not good passwords.

Do you have a solution?
[Android Head-Units] PsychoMcSatan:
Sorry, haven't contributed to this forum in a couple years, but my unit was running with no issues all this time until just recently it started displaying Chinese erotic ads and it's constantly trying to install something called "SystemUpgrate". In any case, it seems it's time to wipe the system and reinstall, but I couldn't find my old source files.

I'm a little shocked to see an image is being sold for $25!

Is there any place I can get a stable (free) image? Rooted would be nice, but not if it exposes me to these Chinese ads again. It doesn't have to be the most recent, just something stable. I think I had been running an image from a couple years ago.

Thanks!
[Android Head-Units] StuBFrost:
If you mean red mod then it is $16 for the dual core image and well worth it in my opinion.
[Android Head-Units] PsychoMcSatan:
So where does one "purchase" this firmware?

And what are its advantages? Is there a review or screenshots somewhere?

Thanks!

PS And what are current options for rooting? It appears that Baidu Root may be out of date now.
[Android Head-Units] StuBFrost:
If you go to red-mod.ru/forum (which is in Russian but chrome will make a good effort to translate it) then you can install an older version for free. Then if you like it, you can pay and get access to the latest version. That's what I did.

I think the RedMod firmware is already rooted but I'm not totally certain on that.
[Android Head-Units] Jyrgencz:
Try this (working on D90-810 device)

install from unknown sources - 61808683

Factory Reset / Developer Options password? - 7890

Extra Settings password? - 123456

USB Debugging password? - john@tw-desktop
[Android Head-Units] djblaze852002:
This is correct. I went ahead and purchased it a long time ago because it has fixed so many issues (specifically google play music). I thought it was like $17 though. But either way it worth it and good to support the developer. He is also making a firmware for the quad core head unit that I plan on upgrading to in the future. The free version you can download has just about all the new features. Just a few new things in the new version which I haven't even taken advantage of.

System hanging at boot

Hi all

Have a problem. My AN21U head unit (Silver Edition) is hanging on Android logo at startup. Can someone please give me the links to the latest firmware and full format files so I can do a full system recovery on my head unit? Also if anyone knows how to work out what MCU file I need to download for my head unit can you let me know the link? could do with a complete update on my system.

Hoping I won't have to ditch this one and buy a new one just yet.

Need Identification For an Android Stereo

hi

a friend of mine got an android head unit which i can't identify and i'm thinking of switching my unit with his so please any help identifying this unit would be very much appreciated

Android Version : 4.4

Build Number : Wing_KL70_TL.xxxx (so much numbers)

I attached 2 images with the detailed info
[Android Head-Units] ozmcy:
Inverted touch screen

the mcu version I installed for it to work was : 4.3.2-1-10-2101

in reminder that this is the 6.2" screen with dvd (malfunction after the flash repair) dual core,

you can see the information in the video + download link of the mcu + the firmware :

" youtube . com/watch?v=1VC1o_KocII&feature=youtu.be "

after the flash , in my case, I needed to change the vehicle in the settings (I think I chosed the 3 on the list)

the Bluetooth and the dvd are not working (for me),

but the aux is working, usb seems working, all speakers are working.

so this is the last resort !
[Android Head-Units] drlifewhy:
I've tried your method but my MCU is different so many buttons stopped working so i went back to my MCU but i noticed that every time i switched MCU a Calibration Screen is shown but it doesn't really Calibrate anything so o'm still stuck with my inverted touch screen
[Android Head-Units] ozmcy:
This is pretty weird, on my machine I searched desperately for the calibration screen, and I never found it,

(I still did not found the calibration touch screen) maybe your machine is a little newer than mine,

do you have the 6.2" screen dual core with dvd and a resolution of 800 x 480 ?

if this is the precise unit then I think it should work,

maybe I am mistaken here, and somebody with more knowledge can bright things up.

I can't download tour files

[Android Head-Units] Dukenukemx:
Can anyone explain this RedMod rom and how to install it? Also I don't have a AN21 stereo but a TD730a. I was told my stereo is similar but I have video inputs and outputs as well as well as a DVD player. Would this RedMoD allow those features to function?

I'm interested cause my stereo's GPS has gotten bad and takes like 15-20 minutes to get a lock. Resetting the device hasn't fixed it.
[Android Head-Units] Dukenukemx:
Can anyone help guide me on what upgrades there is for my unit? I have a problem with my GPS where sometimes it takes a long time to connect. Sometimes it never connects. Sometimes it takes 5 minutes or 15 minutes. I'm watching GPS Test and it sometimes doesn't see anything in view.
[Android Head-Units] wanxu:
Our unit is Android 4.1, not 4.4, so this is another unit.

Check out RedMod's website. Maybe your unit is the 4Core one: http://firmware-an21.wixsite.com/iqnavi
[Android Head-Units] gangaskan:
ok, i'm trying to figure out how to donate to this guy and i'm confiused.

he says $$ + % commission what does that mean? what is the commission for anyone that has donated to get the firmware?
[Android Head-Units] Charm1418:
While the an21u is stuck at 4.1 some manufacturers modified the menu to falsely claim they run 4.4 when it was still on 4.1. His MCU model number leads me to believe this is a an21u. He could install CPU-Z to see if it is a MST786 dual core cpu for more verification or try to get into the developer menu using these passwords, http://xdaforums.com/wiki/Tonghai_Create_AN-21_U#FAQs.

Probably what the redmod guy means is that you pay the set price and whatever paypal fees associated. Should be a selectable option when you go to pay.
[Android Head-Units] StuBFrost:
Just pay PayPal gift so that you pay the fees and he gets the full amount.
[Android Head-Units] Dukenukemx:
So far everything that works for the AN21u also works for my unit. I'll run CPU-Z and check back. BTW, thank you.

cool, got it. and i just put the files on a SD then boot the device right? its been a while since i updated this thing lol .
[Android Head-Units] StuBFrost:
I put the files on the sd and booted and the unit saw the files and updated. Took a few minutes.
[Android Head-Units] gangaskan:
one thing i noticed is i'm running out of app storage, is there a way to change that? i do think at one point i could move them to SD, but i dont think that option is there.
[Android Head-Units] HellStorm666:
How can I be sure that the firmware will work on my unit?

Is there some app that I can install to verify what unit I have?

Will there, or is there, an update to a newer android version?

(from settings->about device)

CPU is a Cortex-A9 dual-core

DDR3 1GB RAM

Android 4.2.2

MCU 4.3.10.1-1-10-610101

System 2.8.8

DVD 2.12.11-hd860mc

This is the unit in my car: https://www.youtube.com/watch?v=UVcwysXrbJg
[Android Head-Units] wanxu:
When you install an app from APK you can select to install in the internal memory or the external one (the internal 5GB partition). Also I think in the device menu there's an option for switching memories I think. If not, if you are root you can install some app to share memory with the SD (sd card or usb in this case). App2SD or this kind of app.

By the way, I need a 3G Dongle, do you know a cheap one that works for this kind of unit? Or if I need to look for a particular chipset or something like that.

Edit: there was an old message talking about compatible 3G dongles, I managed to get a ZTE MF668A for 5€. I'll let you know if it works when it arrives.
[Android Head-Units] Shadow128:
Hi there,

after long time I'm back with a problem/question on this device :)

I use the android car radio with the "original" 2.9.5 firmware with almost no problems. For navigation I use TomTom, which also works for 99%.

In summer sometimes it needs a little bit longer to find gps signal, but it worked. But now with colder temperature it has more and more problems to find the gps signal.

Don't if its really related to the temperature, but it is very strange. Sometimes it works, often in that case, I don't need it.

And if I need the navigation, it's searching and searching. Curious.

Anyway...

Is there a possibility to use a external gps device on bluetooth? Or maybay a serial gps device?
[Android Head-Units] gustavocwb:
I would really want to know this too!

My GPS isn't working for a while and I don't wanna buy another unit, my chances is that I could use a external GPS by bluetooth or something, just to get my GPS back.

Regards
[Android Head-Units] wanxu:
Hi guys, actually RedMod firmware has added to settings an option to use external GPS drive. I don't know if it works with bluetooth GPS, but at least wired GPS should work.

By the way, ZTE MF668A usb 3g works but I am not able to select network manually.
[Android Head-Units] Shadow128:
Mmh, ok. Means new installation of firmware and apps, but ok ;)

Do you've any experience with RedMod and external GPS? Its working good or does it have also sometimes problems with the signal?
[Android Head-Units] wanxu:
You don't have to reinstall anything. Just do a system update and everything will be there. Actually you can go back to 2.9.5 without losing anything if you don't like it.

I'm using the original GPS, sorry. In the description it says it has improved GPS signal.
[Android Head-Units] Shadow128:
Ah ok. Only system update is good :)

Maybe some can tell more about bluetooth connection to the gps receiver. Is there a english-speaking forum for the RedMod-Firmware?
[Android Head-Units] wanxu:
Check the forum: http://red-mod.ru/forum/ I think everything is in russian, though. Maybe with the translator you can get what you need.
[Android Head-Units] Shadow128:
OK, I looked onto the red-mod Forum, but I'm wondering about the price for the firmware?

I can download it and use it 100% for free, and the $16 are as donate for the developer? Or are there any benefits if I pay for it?

And are there any other advantages with the RedMod firmware?

For the GPS receiver I searched on Banggood and found these two gps receiver:

Has anyone a working mirror link solution with the AN21-U (mirror phone to headunit with touch controls). I tried a couple of the EasyConnected apks, but none of them worked. Any ideas?
[Android Head-Units] legrimov:
Could you say me the SOLUTION FOR THESE PROBLEMS (Please answers me):

- Noise when Play music or use Bluetooth. (Noise Backgroud, I change the mic and try without it, but nothing)

-Internal Memory is on READ ONLY mode, and before was in READ AND WRITE Mode. I dont do anything to put this Mode. So how It is on READ ONLY mode I cant download archives from web but for another way I can download apk from Play Store.

(I tried a reset factory, but nothing.)

-Sometimes it has problems with Play Store and I have to down it to the factory Play Store apk and finish the process, for a solution by a time.

Have you got any of these problems? If you have please say me which solution have you got.

I think the problem maybe is a corrupt backup factory, so I want to try to install the last firmware. Do you think so? Have I to install the last MCU too or it is not necessary?

Very Thanks!!!!!!!

I have some doubts:

Last Official firmware and RedMod 0.3.1 is for the same things? I don´t know what is Redmod.

Have i to install new MCU for the last official firmware or it is not necessary? Because i read that is very dangerous install MCU.

In the official version 2.9.5 does not appear that belongs to the resolution 1024x600 as if it does in version 2.9.3

Did you taste this?

Because there are two files? How is it installed? Is it put directly into the SD and is it already? I thought only one file would be necessary.

All of these firmwares are in Spansh?

The problem i want to resolve is Internal Memory is fix ONLY READ and not READ AND WRITE so i cant download from web.
