Does it work on 2.8.7 too ? 'cause the Radio App layout in 2.8.6 .... :eek:
[Android Head-Units] cool_head:
Yes, working. I've tested in 2.8.7.. That radio app in 2.8.6 really s*cks.... Hey btw when you come to Portugal i'll buy you a beer ok? :good:
[Android Head-Units] kaween:
Heh. Be careful what you wish for, I might hold you to it one day. :) But for now, I'm already glad you're glad.

Or something. :D

I suppose the 2.8.7 is the "WinCa" layout ? I might go for that one.

Any issues ? UI warning messages and stuff ?

Any luck with the Huifei DVD player ?

Also, please test TT's behavior in terms of audio please. Does it "fade and return" correctly to and from the active audiosource when giving voice guidance ?
[Android Head-Units] cool_head:
The 2.8.7 have the same layout than 2.8.3.. It has UI red warning too but it seems stable. TT works great. Even the audio fades.

The DVD player works great in this unit, but it will stay in the Huifei HU. I just tested to confirm the other drive's death.. Maybe one day I'll try to flash something in it.. heheh

Oops. Missed that question :

Igo : use any file explorer type program to go to your storage location. The Igo directory still should be present. Simply launch the Igo apk again from there and it will install Igo back.
[Android Head-Units] blaaaah:
I'm currently on system version 2.7.28 an my MCU is still the original 4.0.6-1-10-0101 (I have never updated it).

I'm experiencing problems with my audio and some apps have recently started to not open correctly (e.g. Sygic). Audio problems include third party applications not having any audio, unless I firstly start the stock Music app and put it to pause. This seems to "unmute" something and I can hear sound from e.g. Spotify.

I was thinking to update my unit to 2.8.7 and also updete to MCU to more recent one. Any suggestions? After the update I'm going to make a factory reset also.

If the 2.8.7 has the UI red warning, how can I get rid of it?
[Android Head-Units] foggydew88:
I agree, and for the 1st time I don't have problems with Buetooth/phones connection.

I can say that for my unit (8-10-E501) the association between MCU 4.3.5 and OS 2.8.7 is the state of the art.... at the moment :cool:

Slán!
[Android Head-Units] kaween:
.... Which makes the UI warning even more annoying. ;)

Crossing fingers and hoping for a fix in the not-too-distant future.
[Android Head-Units] foggydew88:
Just root and use the com.tw.service_a5a4.apk from the 2.7.39, it's a 5 minutes job :fingers-crossed:

According to what I've been told by people here, that trick does not work with 2.8.x .

Screenshots of 2.8.7

Hi,

I just finished upgrading the bluetooth module to a BC6 (see the hardware thread for more info), and during this task I upgraded to 2.8.7 and MCU 4.3.10-1-10-210101.

Here's some screenshots of it:

Also:

MCU upgrade fixed my radio EQ reset problem.

Still able to root with Baidu, but also still not persistant during reboots

Did you try cool_head's method from post 5360? Worked for me on 2.8.6.
[Android Head-Units] shadowmike:
So I updated and now the the touch display is off, and I can't properly navigate the radio.

Edit after a bit of stupidity, 600x400 is the firmware I want....

I've installed 2.8.7 , but cannot get root. :what:

Everything else seams to work with no mcg update so far. But this red text will aggravate the he'll out of me.
[Android Head-Units] foggydew88:

[Android Head-Units] shadowmike:
I've tried that, the Russian version.

I think my problem was and is, I'm attempting to install superuser , it says it installs. But I still have no root.

After further checking the baidy app, looses root after leaving the application.. so I actually never get root even though it goes through its root process
[Android Head-Units] foggydew88:
Inside the RAR packet there are all the files that you need:

- The 4 system files to aplly with the system update menu procedure AFTER the 2.8.7 upgrade

- Chinese Baiduroot

- CWM Superuser apk

- Instruction.txt

Internet could be necessary only for the su binary update after the CWM Superuser apk installation.

Slán!
[Android Head-Units] shadowmike:
One moment.

After I update the 4 files my touch screen is virtually unresponsive, touches are no where near where I'm touching. So there's no way of using the head unit.

Edit after replacing the 8d8d1b1a-ea4a-11e2-a661-000c29ba27c0 file from the 2.8.7 update in the root files I have a responsive touch screen.

Attempting root.
[Android Head-Units] foggydew88:
These 4 files simply reset most of the custom unit configurations without touch the data partition.

AFAIK no one of them erase the screen calibration.

Try to make a factory reset and/or reinstall system and correct MCU for your unit with the startup procedure.

P.S. I read some of the past threads, what kind is youir unit?

[Android Head-Units] foggydew88:
What's your MCU ?
[Android Head-Units] shadowmike:
Mcu 4.3.4-7-10.6501
[Android Head-Units] foggydew88:
Decoding your MCU sign, yes it results to be a VW model (10.XXXX)

but the 65 (hex) means binary

1

1000101

and the bit7 is "1" that AFAIK means NODVD unit, and in the pic that you posted I see that it has the DVD drive.

Are you sure about your MCU model?
[Android Head-Units] foggydew88:
Good lesson Miwer :good:

and at the same way it's recommend to not apply any update that's not provided by the official reseller, everything is made with experimantal intention and has a part of risk, up to the possibilty to "brick" our unit, and it must be clear at the biggining.

hands-free produces echoes and Navigon crashes

Hi everybody,

I´ve read here a lot and got some good hints for our device. There are only two problems left to solve.

1: My hands-free doesn´t work properly. The person I talk to always hears the own voice when I´m driving or when the speakers are a bit louder. This is really annoying and not really good to use. I have the version with integrated micro and the possibility to use an external micro on the backside. Therfore I´ve taken a 3,5mm extension but have not connected a micro yet. So I need some help to get this double sound eliminated. Any hints?

2. Navigon crashes regularly and starts again. I´m using a Class 10 MicroSD and I also tried to move the folder to the internal storage. I also want to try another MicroSD and USB-Stick. Does anyone know how to fix this problem? Another info is that the voice is sometimes not fluently. Maybe there is a performance or speed problem?

By the way I tried Sygic also and I´ve got the same problem here. So it seems to be an internal error or not?

Thanks for any hints.

Sinner

PS: Does anyone know if it is possible to run Navigon Selct on this device when a 3G Dongle (and so the imei of the dongle) is connected?
[Android Head-Units] wanxu:
There's an option under Settings/Extra settings about SD Speed. You can set it to Full speed in order to avoid these kind of failures. However, I would install on the internal memory (or internal SD) the navigator, rather than external device.
[Android Head-Units] Sinner75:
Hi Wanxu,

thanks for you reply. I´ve tried the internal storage but got the same crash of the navigator. I had a look at extra settings but there is no option for setting the SD speed.

My Device

Android Version 4.1.1

MCU 4.6.6.1-7-10-6501

System Version 2.6.70

DVD Version 2.13.12.2-860mc

In my menu I have to select Settings then general and the extra settings with the code 123456 or do you mean another extra settings?
[Android Head-Units] foggydew88:
My unit had the embedded mic too, but as you can hear it's useless, I made by my own the hardware modification and now I use this external mic that's working very well.

I don't know about the double sound issue (I never got it), but with the external mic is another story.

[Android Head-Units] Sinner75:
Hi Slán,

thanks for your reply. Do you have an external connector for micro also? Or did you just disable the internal micro to connect the external to those wires?
[Android Head-Units] foggydew88:
I didn't got an adapter for the external mic in my unit, I opened my unit (saying hallo to my warranty), desolded end removed the crappy 2mm mic cell from the board, resolded 2 wires and fixed a 3,5mm mono jack at the back panel.

Slán!

^^^^

it's godbye in Irish not my nick ;)
[Android Head-Units] Sinner75:
Ah, okay. ;)

So foggydew88, thanks again. I think at first I will try the external connector with a new micro and if this will not work I will try to disable the internal micro. My warranty might be gone also because the seal broke when I inserted the device to the frame. Really annoying that they use such a seal which will be damaged so qickly. But that´s not the point. ;)
[Android Head-Units] foggydew88:
I think that if you plug the external mic it will disable automatically the internal one, hoping that the 3,5 mm female jack on the unit has the switch. :fingers-crossed:

Hey guys I've made a firmware package (2.8.7 system image + 2.7.37 boot image) that doesn't need to flash the 4 files that I've posted before. You just need to install this firmware like usual (System update), install BaiduRoot and then CWM Superuser.

YOU WILL NOT

loose root in every restart. So, you can forget the other package that I've shared with you.

[Android Head-Units] Miwer:
Hi cool_head,

That's nice and all, but I think it's worth mentioning, that this is a mix of update files from different versions - the system image is from 2.8.7, but the boot image is an older one from 2.7.37 (this one) - so this is not technically a "patched firmware". This is certainly not an official firmware, and it

cannot be stressed enough, that unforeseen problems COULD arise from using this.

I still think we should be working towards a solution, where we can root the official firmwares.

I have created an issue at Superusers github tracker, hoping that someone can help us.

Cheers,

/Miwer
[Android Head-Units] shadowmike:
I'm positive that's my mcu, lol. This isn't my first an21u I had the same radio 6 months ago. 4.1 was a lot easier to root than this new firmware

I'll try to get some decent pics up , but this xda app sucks
[Android Head-Units] kaween:
Do not cry my dear. Help is underway.

It's just a setting, nothing else.

Settings -> general -> extra settings code 123456 -> "brake setting". Will probably show OPEN now. Change to Close. (Or the other way round, don't know 100% sure as this old one's memory isn't what it used to be. Should solve your issue)

After installing the 4 files my touchscreen acted as if it where a different resolution, bottom touches would effect the middle of the screen.

Replaced that one file and the touchscreen was perfect.

Where did you get you decoding info from, it's intriguingly accurate and flawed.
[Android Head-Units] cool_head:
Indeed. But really? this is the easyest way to root the 2.8.7.. we only play with what we have. Don't forget that these files are all encrypted ok? Anyone flash these files in their own responsibility.

[MENTION=822076]shadowmike[/MENTION]

You mean the structure of the MCU number and the bit assignments ?

The're multiple threads about them here. None of them are "written in stone" but so far they turn out to be fairly accurate.

To do a fast check, the mcu decoder http://an21u.coldzone.ru/ does a pretty good job.

And cool_head is 100% right. NOTHING we're doing here is "absolutly safe or recommended" or whatever. Heck, I even ruined my unit for a couple of months after an official update from my seller. I'm sure everyone should have enough common sense to realise that there's always a possibility your unit goes belly-up or develops undesired behavior when meddling with non-disclosed, non-supported and non-documented features. :)

I'm glad the're enough nice people risking their units in their search to give us what the manufacturer does not. (Support). Do not take it for granted. Do not blindly follow it. Take it or leave it, criticize it when need be, but do not condemn it. I'm sure we all can agree.

Or as my wife says : in their research labs, there's a large banner hanging on the wall stating, "If we knew what we were doing, it wouldn't be called research ":laugh:

This was all guess work in this thread 7 months ago. My last radio was stolen. I had a lot of discussion in this thread. As I said I'm not new to this radio just the new system. 4.2.2

I do not use a computer, ONLY MY HTC one m8 do do all of my searching, downloading, unpacking, transferring. Etc. I have not owned a computer in over 4 years, so some of the research is a bit difficult at times.
[Android Head-Units] kaween:
I know you're one of the early adopters of this unit, Shadowmike. I used to lurk this forum when I was still trying to make peace with my S150 so I do remeber you. :)

Didn't know about the theft though. Sorry to hear that, and I hope none of us ever have to face something like that (...again, in your case).

And unless I'm badly mistaken, none of this is "true 4.2". It's all 4.1 disguised under a 4.2.2 banner and ultimately _false advertising_. :) as you're undoubtably aware of.
[Android Head-Units] shadowmike:
I've also read about the 4.2.2 fake banner. But it's a Chinese patch job, they have iPhones with better features than a iPhone....

Btw my model choice has bc6 ... That from what I understand is the better bluetuth that can do odb ?

any better instructions to installing 2.8.7? I know we update like older version but these new version look great but that ui warning is a killer.

Can I then install those APK from your folder, ex. car radio. will my car radio be upgraded to the 2.8.6 car radio style?

I really want to root to get my obd2 Bluetooth to work.

last anyone one have a guide to get the OBD2 to work on these radio.
