Maybe its a problem with the UK sourced Vodafone branded ones???

I am running stock 9.0.3 ROM rooted with magisk and bootloader unlocked. Since i don't use root functionality that much so i have decided to unroot and relock bootloader.

Do i still need to flash stock ROM again? Or just uninstalling magisk will be enough? Any guide about this?

Thanks
[OnePlus 6 Questions & Answers] Chinaroad:
Relocking the bootloader means you're going to wipe everything, so flashing oos is not your biggest problem, so wipe everything, flash oos(i guess you'll get the stock recovery back too), and then lock your bootloader again

[Android Head-Units] iulian_cosmin:
Looking to buy a new android head unit, after some research , most likely I would go for one of the 2 below:

Dasaita Android 9.0 Car Radio 2 Din GPS- 2018 PX6 Built-in DSP IPS Screen 4Gb+64Gb 6-Core RDS WIFI Bluetooth

Joying New 10.1" 1 Din TDA7851 Android 8.1 Car Radio Player Multimedia GPS Navigation Audio Stereo DSP

Dasaita is a 6 cores - 2 cores running at 1.8Ghz, 4 at 1.5 Ghz, the benchmarks shows this unit performing better on the single core test, Joying is winning the multi-core. Not sure how much of a difference is going to be in a real life normal usage. Both units should perform nice. Joying unit comes with the new 8 core Intel SC9853I with 1.8Ghz per core, from what I read on this forum, looks like this product doesn't feel as solid as the Dasaita unit, still things that are being fixed through monthly updates from the manufacturer. Joying has SPDIF Coaxial digital audio output, Dasaita has HDMI out for video as distinctive features for these two units. One big concern would be regarding the Joying unit that it might get hotter than the Dasaita unit plus the not so polished software. Not sure which one to go for, I would appreciate your take on this, if you own any of these 2 units. PX6 RK3399 or Intel Airmont SC9853i ?
[Android Head-Units] julien_blanche:
Hi, as being switched from px5 to the joying intel sc9853i head unit, i would definetly choose the dasaita px6 for below reasons;

1- Cpu power does not means everything and intel cpu gets very very hot 80~100 C during summers, of course this could be avoided by adding extra fan along with a heat sink but small one hence there is not much space inside the cage

2-PX6 is most known platform and lots of flexibility cos its a well known product unlike the joying intel head unit

3- Software of the joying is terrible, there are a lot of bugs and those will be affecting your daily driving experience and they will make you crazy after a while believe me

4- There is a joying support only allegedly, most of the time they can not be able the solve the problem and that garbage intel head unit has a lots of way to go to become a normal daily usage head unit

5- SPDIF is not a game changer option by itself, i have done side by side rca-spdif outputs and there is a very tiny difference in terms of audio quality

6- There is no xposed framework support which is tremendous effect on head unit ( I am putting this as a standalone remark hence this could fix the some of the bugs)

I hope these are the answers which you looking for..

cheers..
[Android Head-Units] surfer63:
The PX6 can also become very hot. Same issue with all the faster CPUs.

Another point is rooting/Xposed/custom roms: I'm sure that Malyask has a PX6 custom ready in the near future. He already made one for the PX30 (don't buy a PX30).

And HAL9K most probably will have a PX6 custom rom pretty soon as well as he is "sponsored" by some Australian vendor of those units.

Due to the new flashing technique used on the 9853i (compared to the Joying Sofia and PX5), it is now also possible to make a custom rom for the 9853i. (but as long as my PX5 is working properly I will not switch to a 9853i and maybe never).
[Android Head-Units] SunDevil84:
I have same dilemma as you. I tried to list out pros and cons for each in my opinion.

Above all else, I just want it to sound really good.

Dasaita px6 dsp pros:

Android 9 vs 8.1

Rockchip platform seems to have more longevity / development vs intel ?

Mali 864 vs Mali 820 (not a huge deal)

Faster single core performance

HDMI out (nice to have)

2 camera inputs

3 1.5 amp usb outputs

Cons:

Need to purchase android auto / carplay dongles separately (100+ for both)

No spdif out

Screen not easily / quickly removable

Unsure if canbus adapter for chevy cruze is compatible

Joying 8.1 intel DSP pros:

spdif out

android auto / apple carplay support built in via zlink

Easy to remove screen

Seem to have good technical / customer support?

Joying makes a direct 7 inch oem style replacement for my 2011 silverado vehicle, which makes getting harness / canbus adapter easy....

Faster multi core performance from CPU

Cons:

No video out

Android 8.1

usb / bluetooth limitations?

overheating issues potentially (live in phoenix lol)
[Android Head-Units] BlinkyTrojan:
I personally still using the 3 years old PX3 from Joying.. had twice the screen replaced for free due to cabling fault

and by looking at some reviews for the new units and build quality, I'd say they are quite good. They even produce variants screens like the 8" one that looked pretty solid.

The only downside I may think of is only the Android/software support for the Intel units. You are pretty much only relying on 1 single seller/manufacturer for the updates, unlike MTCx units.
[Android Head-Units] ozzyboy:
WOW! Also I'm in big dilema ...which HU i'll have to choose: joying, xtons, witson, eonon, daisata, so many brands .... I was determinated on Joying with Intel SC9853i, because at this moment they offer HU with best hardware specs on the market, but after I read this thread and this one I have big reservations.... For me and my car best fit is a HU with buttons, not only touch. I prefer this ones because they looks closer to the original media player.

So, after 1 week of searches, digging, I have to face it with this conclusions:

-Joying have best hw specs on market, 8Cores Intel SC9853i, built in DSP, responsive support, but many bugs;

-Xtorns have a good build quality on their HU, maybe the best, sadly NO built in DSP, more expensive than competition, they have 6Cores PX6 on their lastest HU, not so much info on this forum about xtrons and their rom stabiltiy or support;

-Witson, I'm witson old HU owner, quad core, 1GB ram, and the experience was average, because the lack of ram memory, but after 2 years it still working. Now they offer 8Cores Px5 with a fair price, NO DSP, also not much info about support

--about other brands I have no knowledge, so no opinion!

After this conclusion, now I'm aimed on Xtrons, but in no hurry! I think if they had DSP on their unit, it was a 1st choise for me...so I have to find more info about user experience with this brand. Maybe someone share his experience/opinions about xtrons , and why not, about anyother brands to complete this thread!

THX!! :cowboy:
[Android Head-Units] yurtesen:
Very hot is a relative subject. The question is does it become as hot as Intel and throttle? I think in the past also Intel units had more heat related issues than other units. But more importantly, you never know when Intel will stop supporting the platform. It is new and risky.

That said, Joying Intel units have 2s boot. I haven't seen any PX6 unit which claims to support this. I wonder why? as PX5 units had this feature???
[Android Head-Units] surfer63:
Of course heat is relative. But the PX5 definitely got hot and started throttling down. Cooling it was one of the first things I had to do. I was not able to find the specs back, but the px6 iss comparable to the PX5.

Lots of home media units contain PX5s and cetainly need a big heatsink. Based on same spec measurements I guess it is the sam for the PX6 (but I can't prove, as I can't find back these measurements :()

the 2seconds startup has nothing to do with the CPU, but with the additional hardware: the MCU and MCU firmware. Only the FYT based MCU types can do this.
[Android Head-Units] yurtesen:
[MENTION=2550900]surfer63[/MENTION] it is interesting information about 2-3s boot. But why FYT does not have PX6 units? To be honest, right now I am not able to find any PX5 units with fast boot even.
[Android Head-Units] surfer63:
I don't know whether they have or have not PX6 models. Joying only has the 9853i models from Fyt. There are however more FYT resellers than Joying.

Why do you want to have a PX6? You want a good functioning unit with as few bugs as possible. Performance wise it doesn't make a big difference, if any.
[Android Head-Units] ikerg:
The downside for Intel socs is the precious trial with Intel Sofia units.

Manufacturers bet for Intel two-three years ago and moved fast again to rockchip platforms leaving Intel Sofia's with no support

In my opinion dont let be tempted by hardware specs...here the key is the software.

These units have hardware enough for the extrnse use for the car environment....if software is not stable....then your headunit is useless manufacturers don't give you the correct support (the most often case) then you have to move to any developer support....

Today the MTCD/MTCE based mcu units are the best developing supported (thanks to malaysk and hal9k) both are moving to px6 now.

With respect to which brand....in my opinion...many manufacturers claim warranties but no answer when troubles appear. I can recommend Dasaita (you can read many posts in which dasaita has been made the correct support for customers)

[Android Head-Units] MIndrunner:
I followed Intel path for 2 important features that matters for me:

1. Fast boot. My unit is up less then 1 second and this aspect is very important.

2. DSP that gives a much better sound quality and settings compared with any PX solution I've tested.

And another big factor that made me decide was that HU i bought looks 100% like OEM unit including UI menu and is plug & play for all car features. Is not Joying brand but is based on same FYT solution. Now i am looking to find a way to root this device.
[Android Head-Units] Kingjewlz559:
How bout the nee Belsee 9.0 units? How do they compare? They have a plug and play for the 9th gen accord. Cant find any info on Belsee
[Android Head-Units] ricanxd:
So is that fast boot a hardware thing or software based?
[Android Head-Units] surfer63:
Both. It is done by the MCU hardware and MCU firmware from FYT. It is not in the android layer. That is only reacting on it.
[Android Head-Units] ikerg:
Px units have a sleep mode and waking up from sleep is instantaneous.

During sleep just few mah are consumed.. so no worries on draining battery

Px u mints have also dsp...did you tried a px with dsp before to be compared with your fyt with dsp?

Enviado desde mi SM-G950F mediante Tapatalk
[Android Head-Units] surfer63:
The non-FYT PX units have a sleep mode of 5 minutes to something like 2 hours. Within this time frame they wake up instantanious. After max. 2 hours (or so), they switch off completely and cold-boot again needing 25-45 seconds to get to live again.

The FYT-units, both Intel and PX units, have deep-sleep and a 2-4 seconds wake up (the extra 2-3 seconds due to the MCU). Also after 4-5 days this wake-up is still 2-4 seconds!! And it does not drain your battery. The current is so low that a normal car battery can at least last for 30+ days before reaching 50% load, necessary to be still able to start the car.

That is a huge difference between the FYT units and the non-FYT units.
[Android Head-Units] ikerg:
That is not true.

Px units (like mtcd) have a unlimited time sleep mode.

Just when detects low voltage of battery they shut down.

I had my px5 5 days on sleep mode without issues and waking up instantaneously

Enviado desde mi SM-G950F mediante Tapatalk
[Android Head-Units] surfer63:
That is really great to hear. Until now I was really under the impression that only the Joyings did that.

You mention the PX5 (mtcd). Was that also true for the PX3 (mtcb)? I have seen many videos/images where they showed in the Settings this "switch off after xx minutes" (or whatever it was exactly called).

For me that was the only reason to choose a Joying. Cadillac Mike did quite some reviews where he also discussed the mtcd units and the Joying. He specifically mentioned the quick-start of the Joying. Unfortunately he removed all non-Seicane videos from Youtube and now seems to be paid by Seicane (and changed to 5after12 as user name).

And as all mtcd units are compatible: does that mean that what you say is valid for all px5 units?
[Android Head-Units] ikerg:
On my px5 still the Menu allows you to choose between some.time to shut down or auto sleep....if you choose auto sleep...it lasts for days prioritizing the battery of the car as now it has a voltage meter to achieve this

I received my Dasaita Android 9 4/64Gb RK3399-PX6 today and it's been rather a mixed bag. It's easy to assemble and the screen looks lovely, but I'm having a bunch of problems with it, and I'd be interested in knowing if other people have seen them too.

Firstly, settings confirms that it's a PX6 with 64GB flash, but it only has 2GB memory rather than the advertised 4GB:

Model & hardware

PX6(1024x600)

Android version

9

Build number

rk3399-userdebug 9 PQ2A.190305.002 20190611.144108 test-keys

Kernel version

4.4.167

#320 Thu Jun 6 17:27:26 CST 2019

MCU version

MTCE_HA_V3.14_1

Jun 3 2019 17:09:27

CPU

Dual-core Cortex-A72 @ 1.8G

Quad-core Cortex-A53 @ 1.5G

Memory

1959 MB

Serial number

<redacted>

Also, I can't get the advertised 1s wake to work, it always boots from scratch, taking around 26s. I've tried setting it to "auto sleep" rather than "shutdown after 30s" as I had to do with my old (Pumpkin) px3 head unit, but the Dasaita always does a full boot.

It comes with a single USB cable and a dual USB cable. If I use the dual USB cable, all is well. If I use the single USB cable (even if nothing is plugged into it) then there's a 3 to 1 chance of it preventing the unit booting. The touch keys flash briefly, go dark and then it just sits there, refusing to boot.

Finally, when you give it some welly, the sound is great, but with quiet music the hiss and noise is much worse than my old Pumpkin.

Apart from these rather glaring problems, I'm impressed with the performance. The px6 board is obviously a lot faster than the px3.
[Android Head-Units] BlinkyTrojan:
You should check with Dasaita and crosscheck your order if you have purchased the correct unit with 4GB RAM or they indeed sent the wrong unit. IIRC 64GB unit always pair with 4GB RAM but i might be wrong.

I just got my MTCE/PX6 unit but not Dasaita. However, everything works just fine, including the 1s boot even after sleep for a day with "Auto sleep" option. Is your unit shows "Android is shutting down..." after key ignition is off? Or else, you might need to check ACC / BATT connection.

The single USB might be considered USB-OTG (to boot from USB recovery), or in other case, for Android Auto or Carplay.
[Android Head-Units] motecbb:
I'm considering buying this unit from Dasaita, what do you suggest? I haven't found extensive info here on the pros an cons of the unit.

Please update us on your usage experience.

Thanx
[Android Head-Units] markbanang:
I've started to talk with Dasaita via Ali Express messaging, so hopefully we'll be able to sort something out. I'd be happy for them to send out a replacement PX6 board rather than a whole unit, but we'll see how it goes.

It does show "shutting down", yes. I was looking into the ACC/B+ things last night, and I think the cables are swapped on the ISO harness, which would explain the behaviour I'm seeing.

That's possible. I'll try plugging a USB stick into each of the USB ports and see which are enabled for OTG.

---------- Post added at 09:07 AM ---------- Previous post was at 09:03 AM ----------

It's very early days for me, and PX6 head units in general, so you might want to go for a PX8 based unit if you don't want to be at the bleeding edge.

If you don't mind coping with teething problems though, the PX6 is substantially faster, smoother experience than my old px3, which often couldn't even finish updating even a single app in Google Play during the 20 minute drive to work.
[Android Head-Units] markbanang:
I've just sent the seller a picture via Alibaba message centre and they've suggested sending me out a replacement core-board, which should be fine.

Yes, it does. I've had a play with this on my desk with a controllable power supply and I found the following:

Disconnecting ACC, leaving B+ & GND connected results in "Power off - shutting down" and a fast boot, as expected.

Disconnecting B+, leaving ACC & GND connected results in and immediate power off and full boot, as expected.

So neither matches up with the car, where Turning off the ignition results in a "Power off - shutting down" but then the head unit requires a full boot.

The next step is to get the multi-meter on the car ISO connector, and make sure it's wired correctly.

Another thread suggested the head unit might power off completely if battery voltage drops below a certain level, but I wasn't able to get that to happen on the desk. I went as far as 10v, but as long as I only disconnected ACC, it went to sleep and woke up quickly.
[Android Head-Units] surfer63:
Do you have a Volkswagen/Skoda/Audi/Seat?

In that case your Dasaita iso connector is good. VAG messed with the wiring.

Their units use a CAN-bus signal to switch off, so VAG doesn't care whether the wiring is correct. Mostly both cables are 12V continuous (in my skoda) or both are 12V ACC, instead of 12V CONT and 12V ACC.

If so, you can use my workaround. It is of course for a Joying, but if you are even a little bit technical it should be easily "translatable" for your Dasaita.
​

otherwise I don't know.
[Android Head-Units] yurtesen:
The question is how much current in mA does unit use when sleeping in this mode?

I mean, is it the same type of sleep like other units use when time is used? Like 300mA-500mA power?
[Android Head-Units] rigattoni:
The power consumption in sleep mode is reduced to keep the volatile memory. That means you can expect not more than 0,5mAh in sleep mode.

This I measured in my PX5 and in the SC9853i.

Additionally:

If the unit is not able (due to software issue) to reach the sleep mode, the unit switches off completely after 20minutes.

This has been tested on my SC9853i.

In PX5 you see the shut down to sleep, because the shutdown is visible. I think there is no difference between PX5 and PX6.

In SC9853i, the screen light is switched off, but the unit keeps alive for ~30sec during shut down. This is only visible in special light conditions like sun light from the back.
[Android Head-Units] riosra:
Dasaita and SYGAV (Android 9) are MTCE head units?

These specs you posted look real familiar. In late June I ordered the SYGAV Android 9 head unit with the following specs:

Model: PX6 (1024x600)

Build: rk3399-userdebug 9 PQ2A.190305.002 20190611.144108 test-keys

Kernel: 4.4.167

#320 THu Jun 6 17:27:26 CST 2019

I didn't bother scrolling further, but it seems that the SYGAV head units are unbranded Dasaitas; in this case an MTCE.

There's mention of development by "hal9K" and others for these units. Where can I find information on this?

Newbie here, but quick study.

Thanks in advance!

[Android Head-Units] thierry34:
i up this thread to ask one thing. you told unit keeps alive 30s .. and turn off completely after 20 mns.

for mine unit, when i turn off my car and remove the ignition key, the screen turns off after 2 or 3 seconds , remote (for power dsp,amplifier and multimeter screen) about 5 minutes. (i timed) . after that, do you mean unit turn off completely after 20 minutes too ?

have you ever had a problem with battery which runs out after 2 or 3 days ?
[Android Head-Units] rigattoni:
No please read again...

The 20min shut down is only triggered if the unit has no clamp15 power and the unit is not able to get into the deep sleep mode. In this case the unit makes a hard switch off. After this happened the unit will clean turn on with ignition. Until then the unit s completely off with no power consumption.

I never had issues with my car battery even if the car is not moved for 10 days. (This is until now the longest time the car was parked at the airport). After returning to the car, the unit wake up from deep sleep as normal.

The 5 min delay seems to be too long. I measured a delay of 30 sec. until USB is switched off and at the same time all other connections are terminated.
