I'm on, could root, successful, but now when I run SuperSU it just says that "binary is occupied"

i find another user with same problem but no solution

I can successfully install root via app manager not over the file manager!

FYI - 4Gb RK3368/PX5 MTCD units have started appearing on ebay . . .
[MTCD Android Head Units General] Bose321:
Interesting. I can't imagine you would benefit from more RAM with normal/simple usage though? Would be great if they fixed their existing problems instead of slapping on more RAM. :p
[MTCD Android Head Units General] typos1:
The extra RAM helps future proof the units - if the KK and L units had 2Gb they wouldnt have the lag problems with the standard ROM, if later versions of Android require more RAM then the octacore SoMs should still be ok.

Plus I was never impressed with only 2Gb RAM on the octacore units - I expect at least 3Gb on octacore devices.
[MTCD Android Head Units General] :
I found my mistakes:

1. Kingoroot can not install > in warning screen open message and force to install (thanks @ ikerg)

2. supersu install not successful "binary is occupied" > see here on youtube or use attachment. After install you can update in playstore with no error!
[MTCD Android Head Units General] :
has you a link?
[MTCD Android Head Units General] echudoba:
There's a way to un-install su in its menu. I can't remember what it is called. It will remove the binary thinking it is its own. Then re-install su and it will work. Also remove Kingoroot and superuser.
[MTCD Android Head Units General] :
Superuser is not insall with Kingoroot here

It works fine and i'm happy

Can i male a backup image and install to another radio?

ist ja auch nur für den fall das etwas schief geht.

Hello to all,

sorry for my English. I want to ask if you can tell me where to retrieve the latest MCU update for my car radio (Xtrons TA701PL with PX3-GS) and Firmware Android 7.1 stock.

After a change I put more firmware but I want to go back to stock.

Hello everyone !!

Quick question: is there a way to avoid "loosing audio" when the rearview camera gets activated? I know rearview camera is activated at MCU level so this will require some trick there (to ask MCU to use video from rearview camera but audio from PX5)

Thanks !!

Max
[MTCD Android Head Units General] echudoba:
There is a place in settings to control the rear camera, audio, lines, mirror, etc. I don't know the name as I am not in front of a hu. It IS NOT factory settings, above that.

http://r.ebay.com/bWPpWZ

I installed mine today and drove it for 3 hours. Key observations are it did not stutter at all, and the screen is good but maybe not as good as a 10" Joying in bright light. I run several big apps so 4gb is useful to me. The SOM is rev. 8 compared to rev. 4 on the 2gb units I've seen.
[MTCD Android Head Units General] typos1:
Youve taken it apart already ? Lol
[MTCD Android Head Units General] marchnz:
Would you consider dismantling and posting pics here. Suspicious that these units contain 4gb of RAM, very easy to make and these would be one of the only units with 4gb SOMs.
[MTCD Android Head Units General] typos1:
No reason to doubt him - [MENTION=744370]ikerg[/MENTION] has contacts with Hot Audio and they said that 4Gb RAM versions would be out soon, then a few months later (a few weeks ago) they started appearing on ebay.

The RK3368 can take up to 4Gb RAM, it makes perfect sense that they have versions with 4Gb RAM, pity they took 3 years to give the RK3188 its maximum of 2Gb RAM.

I ll be getting a 4Gb one soon . . .
[MTCD Android Head Units General] Sylvan151:
Oh sorry. Been a while since i updated my HU.

Question. Can my RK3188 PX3 update to RK3368 PX5?
[MTCD Android Head Units General] typos1:
If you have an MTCD/E unit you can upgrade the SoM to octacore, yes.
[MTCD Android Head Units General] Sylvan151:
I just updated from MTCD HA 2.51 to MTCE HA 2.71

Is this suffice?
[MTCD Android Head Units General] typos1:
It is good to do, but it wont make your unit any faster.

I have a Dasaita 4GB PX5 V600 unit for my 2011 Toyota Camry in transit from China. UPS tracking says it should deliver this Friday. Contacted Quick Yuan directly before purchasing on eBay.

Have still not reopened the device hence no pictures. I will mention however the som is stamped "LPDDR3" which is a clue for anyone interested.
[MTCD Android Head Units General] doener:
I received my Dasiya V600 a few days ago, and installed it in my car today. But I see that when I turn up the Volume > 20. That the HU restarts. Has someone equal issues? Is my device faulty, can I fix that somehow?
[MTCD Android Head Units General] Dyna-Tac:
I did my first update of the MCU on a hot audio unit (v600-ha2151) to 2.71 but now I can't update the system. The progress bar gets to about 25% and then it just stops and 10 mins later it goes into recovery mode.

Why is it doing this?
[MTCD Android Head Units General] typos1:
What MCU did you update to and where did you get it from ?
[MTCD Android Head Units General] Dyna-Tac:
All updates I got from this thread:

I updated to this:

V2.71 (I can't post link due to post count)

Which was successful.

Then I've tried this:

PX5 6.0 UPDATE HA (20171023)

Which I can't get to work, Hot Audio also sent me the above link in a email as well.

I've even tried Malaysk 6.2 firmware and the same thing happens.
[MTCD Android Head Units General] typos1:
OK, what unit do you have ?
[MTCD Android Head Units General] Dyna-Tac:
Hot audio 2151-v600, px5, 2gb, octa core, etc......
[MTCD Android Head Units General] aryanitinkumar:
Hi Dyna-Tac! MCU2.71 is for MTCE devices V600-ha2151 is MTCD hence you should be using MCU2.59.

I think that is the issue.

Hope this Helps :good:
[MTCD Android Head Units General] Dyna-Tac:
I thought MTCE was just a follow on from MTCD. 2.71 does work though!

The unit came with 2.59 installed but now it's gone back to some horrid version.

Anyone got a link to 2.59 as the link doesn't work in post 1.
[MTCD Android Head Units General] typos1:
No, I mean the proper version type like "MTCD HA 2.60-1" or something.

No, you are wrong - ALL MTCD devices can be updated to MTCE - MTCE is simply a software update to MTCD.

Yes, ignore him you are right about MTCE.

What do you mean by "some horrid version" ?
[MTCD Android Head Units General] Dyna-Tac:
right so I used the sd card that came with the unit just in case something wasn't right with the spare one i've been using so far and it worked!

Because I wasn't sure about mtcd/mtce I've gone back to v2.58, good news is I've been able to load PX5 6.0 UPDATE HA (20171023).

In the morning I'll load v2.71 again and all should be good.

Well it went into recovery mode and gave me a list of options I think I must have picked factory reset or something because the unit was awful.

Bluetooth didn't work, dab+ app disappeared and the radio stations were in a mixture of languages.

Hi,

I have a Dasaita HA5404-V600. (Octacore, 2GB, 32GB)

Yesterday i installed MCU v2.59 and ROM PX5 6.0 UPDATE HA (20171023).

First ROM update and after that the MCU update, It works nicely and has nice new features. (for example fuel usage in decimal numbers)

But i have some questions..

1) Does somebody has a link to the changelog?

2) What is the difference between MCU and MTCE? (i read on other part of XDA that MTCE is just a follow up from MCU)

I saw mine was MCU 2.22 so i just updated it till the last of MCU version.

2.5) Or could i update mine to MTCE v2.71?

3) And can i install HCT2_rk3188_7.1(20170511) or HCT2_px3_7.1(20171027) ROM on my device to upgrade to Android 7?

I read many forum post with this same question and someone said yes and others say no.

Many thanks!

Also to [MENTION=6942549]hotaudio[/MENTION] to make this possible.
[MTCD Android Head Units General] typos1:

Then it loops back to bootlogo and start over with optimize apps.

Can someone help? [MENTION=456516]typos1[/MENTION] ??
[MTCD Android Head Units General] ikerg:

An MCU shouldnt cause a boot loop, I dont think its even possible.
[MTCD Android Head Units General] ExoRRSmits:
No rom file was on the usb.

How can i go to recovery menu.

Maybe i have to clear cache or data partition.

I have try to reset the device by powercable and reset button.

Normal i have optimize 63 apps, but after reset 19 or 32 or 25 (it's different everytime)

It bootloops and i have to optimize 63 again.
[MTCD Android Head Units General] typos1:
Yes, you should clear data/cache.

Hold reset for 10 secs, release, then the LEDs will blink quickly press reset again and you should boot into recovery.
[MTCD Android Head Units General] ExoRRSmits:
I'm sorry this doesn't work at all. I can cry! ??
[MTCD Android Head Units General] marchnz:
What else have you thought about trying? Considered reverting to installing factory installed version?
[MTCD Android Head Units General] ExoRRSmits:
Yes, i could..

But i could only if i have access to the recovery menu.

I can't do nothing now.

I was in recovery menu now, i wiped the data and cache partition.

[MTCD Android Head Units General] kennethlee:
Im sorry I did not read all 70 page all the way through. I've searched the forum a bit also without the complete answer. When being a first timer at rooting some of the language is just a step or two ahead, so sometimes it helps just to ask straight up ;)

I was hoping to be able to update my 6.0.1 Android on my GS unit to a newer version, but it seems that my android version i stuck then and the only way to get "updated" is to root a rom that fits MTCE, correct me if im not correct?
[MTCD Android Head Units General] typos1:
XDA rules say youre supposed to read threads first not ust ask questions without reading everything, language isnt an excuse cos you can read it through a translation programme like Google Translate/Yandex Translate etc.

No its not correct, the only way to get an updated ROM (Android) is to wait, you can update the MCU anytime.
[MTCD Android Head Units General] kennethlee:
with the language its not the english which is an issue but the way some things are writen - meaning programming terms etc in some posts - therefore i've read a couple hours on the forum and my questions were not answered by it - therefore the questions. Ill leave it at that :)

Second - Yeah but it seems there are some custom Rooted rooms which might give the unit another feel to it - correct? or what even the use of it
