The wife got me a shield for Christmas 2014. Had it for a couple months, then it started not responding or shutting down randomly. RMAed it. 3-4 months later the new tablet was recalled. Got a New one.... The new one never acted right studdered constantly. At that point I gave up, I used the tablet. But never really set it up, I just put games that I could save to the cloud with. And now it has started shutting down like the first one. So another RMA.
Am I the only one?

The K1 is my first tablet. I'm gonna go out on a limb here and say its probably the worst tablet for $200. I've only had mine for a month. Already returned one cuz the OTA broke WiFi. WiFi sucks hard, constantly getting slow connection warnings on my favorite game (blame it on MM go ahead but my Nexus on MM doesn't have any issues), the reason I bought the tablet was to play it. Screen becomes unresponsive all the time, like 10x a day, sometimes I have to wait up to 5minutes just to open the app drawer, I've resorted to putting all my apps on my HS just to try to avoid this, doesn't help. Battery is horrid, stand by time is garbage, I have to turn it off just to have power when I want to use it again, Misc bug is not fixed. Charging is super slow, charge for hours only gains 20-30%. Support from Nvidia is non existent, posted on the support forums, not one response from anyone except users making excuses for this garbage.
I'm not rooted, completely stock, but maybe I should root to see if I can fix the issues myself but from what I read on multiple sites nothing helps. Will never buy a product from this company again. It's not just u
Yeah the software is buggy. Both Google and NV are to blame here. I've rolled back to Lollipop and Kitkat. Part of the problem is newer versions of Android tend to break apps that aren't updated anymore.
Don't expect companies to respond on forums. NV generally uses them only passively. Forums are a gas can of drama and lynch mobs waiting to explode. You can definitely contact them by other means.

i was contemplating about getting it becuase i need one, but it seems that unfortunately is down to the iPad or a Galaxy Tab S. As much as i dislike Sammy's SW update practice and Apple's lack of features, they are rock solid (i have both ipad air and tab s for my kids). Never had issues with them, but is time i stop hijacking my kid's galaxy tablet
I don't think the Shield is by any means a disaster. If you buy one, stay on the original Lollipop release until NV and Google get Marshmallow more refined. A lot of issues were cleared up with a recent update but it introduced wifi problems for a subset of users so they ceased distribution of it for the moment.
Shield is a neat tablet that is great for games and media. Fast for general apps too and just a great value for its price. Fun optional accessories and console mode capabilities too.

I totally understand about forums but if its an official NV support forum on their site I expect something from them. At least a mod response.
BTW lost 5% battery just typing this ????
I feel like the phrase "it's a good value for the price" is a weak point. It doesn't work.... If it's a good value it works.
Also not on 6.0. I really think its bad hardware and poor QC. I really don't think NVIDIA would have responded to anything.
I was looking at the Galaxy Tab A with Spen but..... The screen sucks. I like the Tab S but I wanted a pen. And there's the Zentab S... I am also playing with the wife's Surface 3 and Android emulators like Blue Stacks.
I've been using the K1 for a bit more than a month. I really haven't had much trouble with it. I've run their 4.4.2, 5.0.1, 5.1.1, and 6.0 releases on it. The problems I've had are primarily with apps not working on all OS versions and this is not really a NV specific problem.
The initial 6.0 had some quirks like the touchpad on their controller was non-functional. Yeah I have the controller. It's interesting and works well, including the gamepad mapper. There is also the apparent problem with the logd daemon hitting the CPU too much and wasting battery. I have not tried the newest 6.0 release. I'm waiting on NV to put it into the OTA system again. I'm not much impressed with 6.0 though because it's a lot like 5.x but adopted storage is not so hot and I preferred the old "move to SD" function (which is gone).
I own/have owned a bunch of different tablets and am used to fighting with Android quirks. I tend to go for fun projects like the old Nook tablets, some Chinese tablets, and Windows tablets. At the moment I have an Onda V919 Dual OS, Tegra Note 7, Venue 8 Pro, and the Shield K1. Samsung might be the way to go if you want the most solid experience. I would read the forums first on that though to be sure you aren't dreaming.
I think I might see if the replacement works. If not I'll sell it and move one.
Of course its not the best, but what do you expect for 200 bucks. That being said my only problem is the build quality, everything else works like it should. Im now since a week or so on 6.0 and everything works, its smooth and fast, no wifi issues. Performance wise its still one of the best Android devices till now, although its about 2 years old.
Here all fine...the only think i can't have working is the stylus only mode and lazo capture...back on MM update but even if I mod the build.prob nothing happen.
Waiting for 1.1 OTA
Where is the source code?
A: It is not released, nor will it be released as it was with mtcB. WTF!
Do the MTCD boards have proprietary hardware and/or software? Besides the MCU
A: Yes. Custom digitizer means you have to buy screen from them. LCD is generic so its replaceable but I have found a reputable dealer. Heres website
http://cowinlcd.com/html/en/index.php?ac=article&at=read&did=113
What are the LCD and digitizer model numbers?
A:depends on the head unit model
10.1 inch version: Cowin and goodix
7 inch versions: ?
Where can I find rk3188 2gb boards to replace the 1gb board?
A:JOYING-There are none. They keep claiming 2gb is coming, but if they knew MTCB boards were slow with 1gb, why are they selling it again.
A:Xtrons-
How are they loading the software onto the board? (Jtag etc)
A: from Rockchips site,
"Support system code download by the following interface: USB OTG interface. | UART2Interface "

Then I'm assuming(NOT TESTED) we can use rktool and flash the update img. Tearing apart the img shows partion paths. This might be the method for user recovery on hard brick units.
Has anyone found any suspicious activity/service/app running on these units?
A: Not yet but since source is being withheld BE CAREFUL of your privacy.
Has anyone used any after market shark fins with these units?
A: Only Radio fins was tested. GPS fins unknown. LTE fins known.
A guy pm'd me an app that sets Poweramp as the primary music player and adds it to steering wheel controls, however the app is specifically for poweramp unfortunately. However, if someone has managed to make it work with power amp, i cant see a reason why it couldnt be re-worked for Google Music?
A: Joying and other brands dont care or have much knowledge. The lack of source code is sad. Its left up to the users which begs the question:
Why is this product so expensive if it runs extremely slow and we have to do all the work?
A:
Is there any way to pull an image of the full MCU/stock software for recovery purposes, or is this one of those things that is really available only from manufacturer?
A: Yes . Online Nandroid on play store. or RKtools.
Where can I get drivers and other useful tools?
A:Rockchips site
If anyone else has questions that get answered here Ill update first post to reflect it.

android system/bootloader/kernel How are they loading onto the nand storage. With certain phones and tablets you can jtag. Others require certain hardware or software to load it onto the board. This is to try to come up with a user method of recovering hard bricks.
Can anyone with experience of MTCB units and MTCD units post some sort of comparison of the two types ?
We can see what the differences are but it would be useful if someone with experience of both types ( @Marius B or @doctorman maybe) could post some comments explaining the hands on advantages or disadvantages compared to the "B" units.
Maybe even open a new thread on the subject of the differences and whether its worth upgrading to the "D" types.
I have seen a question about malicious apps/activity a few times on the MTCD board. Was that a problem on the MTCB units or another? Or are you all just doing due diligence?

what kind of detail do you need.
there are reviews around the net on both..
to my experience right now the mtcD ROM needs major polishing , it is nothing close to mtcB. it is sluggish.
I am so sure that I noticed one boot at 10 seconds but could not replicate it, I am getting 23 seconds boot time on mtcD with latest Joying ROM.
motherboardis rearranged,
it has now 3 UPS plugs on the mother board, only 2 used.
2 wifi antennas but wifi is still 2.4 GHz
GPS antenna is soldered to the coreboard instead of motherboard.
the screen ribbon cable in mtcD is narrower and does not fit the old mtcB connection
touch screens are not interchangeable even though the cable is the same
BT is built in to the motherboard now
I would give the mtcD 6 months to mature up like mtcB units
we now have many developers working on head units and they are joining mtcD as well and bring their work over to these so it will hopefully go faster.

Thanks Doctorman, I think its pretty obvious that MTCD will replace MTCB, a shame in some ways cos of all the work done on MTCB units over the years, it would have been nice to be able to just upgrade the SoM as we did from MTCB RK3066 to MTCB RK3188, on the other hand the MTCD MCU seems to be better then the MTCB MCU and lots of the MTCBs bugs seem to have gone with the MTCD units, its just a case of allowing them to mature lke you say.
I need the steps in order to root my device

Does anyone have an MCTD device that has working bluetooth settings? Can you add and remove devices freely without issues?
The rom that came on my device can't add/remove bluetooth devices from the head unit bluetooth settings page. Selecting a device does nothing. It's as if you don't pair a device once initially prompted, it won't let you change things.
I do, but only phones and OBD2 dongles pair so far. Also most apps other than Torque that would use the BT obd2 dongle think that BT is off in the system.
I bought a Huifei unit for my VW Crafter (I can't post links yet due to my post count, but if you search for Crafter quad core android something like it comes up). Since it is essentially the same as the Mercedes Sprinter, it fits both cars. However, on the VW the dash lights are red and on the MB they are orange. Apparantly when switching to 5.1.1 they also made some hardware modifications. One of them being that the button lights aren't RGB anymore, but only orange. I've already tried to resolve this through the seller by obtaining a new button pcb with red leds, but that seems like a track that doesn't really lead anywhere.
Since I see many people doing hardware mods on these units also, I was wondering whether this is a mod that a local electronic repair shop could do. I've contacted one of them, but they didn't want to do it because they feared the SMD-technique.
I hope you guys can confirm that this is possible to do by a professional repair shop.
BTW, I know I'm to late to the show to sponsor the new unit for the 5.1.1 development. But I would like to show my gratitude to this person anyway, since I'm really hoping the software side of things gets improved soon also and I'm very happy that he is willing to take on this task. How can I still donate to him?

Just make use of the "phone" app, you can delete paired devices there!

There is already an deprecated app for this.
Maybe the developer can help us with this?

No, your head unit is NOT made by Erisin, Erisin are a seller.
Go to settings/about device and see what 2 or 3 letters appear after "MTCD" in the MCU field to find who your manufacturer is.

Can LM Boards be used with some other manufactors roms likely "rebranding"? (or will this cause a soft/hardbrick?)
I flashed on my KGL Unit a Joying Rom. Just the Rom, not the MCU!!
Works without problems.
Can anyone tell me if the modded apps like Bluetooth and Radio for the MTCB units work on MTCD units??
I bought this factory refurbished head unit from Crutchfield. It works, but the user interface is complete garbage, and the functionality is humorous at best.
This device has so much potential and so many features that it SHOULD be an amazing head unit, but I feel like maybe the team that developed the firmware dropped the ball bigtime when it comes to Android phone support. It strikes me as funny that an android-based device would have so much trouble integrating with android devices.
Long story short, I have a copy of their latest firmware, but hacking these sorts of things is a bit new to me. I'd really like to pick this ROM apart and try to improve it, but don't know where to begin.
I am able to extract the system image and manipulate whatever is in it. See attached. If there are any other developers out there with an interest in these head units I'd love to hear some feedback on where to start and what can be done. Kenwood does not seem apt to improve upon this unit (as is evident by the consistently horrible product reviews on any site that contains reviews).

Hello friend, I'm looking into modifying Android head units myself and just found your post. You may want to ask the same question over here....
https://forum.xda-developers.com/android-auto
Hi all!
I just bought an Eonon GA8153A for my Seat Leon. Spec is as follows :
Designed for Volkswagen/SEAT/SKODA
Allwinner T8 Processor
Android 7.1 Nougat
2GB Ram
32GM Rom
Having been involved with tinkering in Android previously. I decided to look if a custom rom was available for it, I can't seem to find anything but I see lots of devices seem to all be the same ones just badged up differently. does anybody know if this unit will be compatible with any existing Roms?
Thanks in advance for any information anybody can offer!

So it's arrived today and I've installed it in my car, operation seems Smooth but seemingly simple feature of iPod connection is missing! I didn't expect that one to be missing. I knew Apple CarPlay was going to be a long shot but I did expect it to still have standard iPod connectivity via the usb cable!
I see there are CarPlay adapters so I'm contemplating ordering one of those for it. Both myself and my wife have Apple devices so would make sense to have the function really.
Before I spend even more money trying to get the head unit to do what I thought wore be basic functionality, am I missing the blatantly obvious to get iPod connection to work?
Hi there,
Recently I bought a PX4 to replace my PX5 radio in my car, a Fiat Punto Evo. The PX5 did work as it should, but I was looking for something new and fresh. Since the PX4 is based on newer technology, and Android 11, I thought this was a step forward. This is an Isudar unit by the way.
However. I noticed the headunit isn't that great. I usually use 2-3 apps (Spotify, Google Maps/Waze and Flitsmeister, a navigational tool for speedtraps and so on) and the radio doesn't perform well when I have these apps opened. Google Maps crashes a lot of times, Flitsmeister freezes and when I want to go back to the homescreen, the screen flickers a few times back and forth. Also, it does reboot all of a sudden.
There is not a possibility to flash or update it since there is zero to little knowledge of the PX4. I'm thinking of the following options:
- Buy a PX6 board and swap it in
- Buy a PX6 headunit
- Maybe there is an alternative
What is a reliable brand in this sector? I see a lot of brands but I don't see the difference...
Cheers,
Jacco
There is no px4 and you don't say if it really is an MTCD type because you haven't posted enough information such as MCU type.
Brands mean little to nothing as the all sell from various factories and are no real "brands" for these Chinese units, only factories.
You want a 7862UIS FYT (4gb+) unit such as what mekede / navifly sell (type 116) These are much less buggy than mtcd type units and you don't need hacky modded firmware to make them work.
Well, there is, it's a RK3566 based one, MTCH_GS_V3.80_3.

Just for clarity, there is no PX4. The unit linked clearly lists PX6.
I no longer recommend the MTCx platform.

Well, actually the details list two options, a PX4 one and a PX6...
But @marchnz is correct in both accounts
1) PX4 is something this guys invented, and is not widely used/accepted (yet). Regarding the CPU they are using, seems to be a slightly improvement/update to the PX5... but very slight improvement (newer tech, more speed per CPU, but less CPUs overall)
2) Even if you go to PX6, those CPUs are old compared to 7862UIS... so buying today a PX6 would be a bad investment. If you really want to reuse the unit and only invest on a CPU board, the only option will be to wait for those manufacturers to adopt the latest chip RK3588 (which has a version RK3588S that looks a lot like a car-oriented chip, even with a CAN bus interface). Of course, you might wait for months and there is no assurance that your MTC-H mainboard will be compatible with it.
By the way, PX5 and PX30 were real Rockchip car-oriented official products. I have never seen any Rockchip original document referring to RK3399 as PX6. I only see this nomenclature on the Android-Auto chinese sites. So, don't kill us if in a few weeks every chinese vendor starts to call RK3566 as PX4
Indeed, I thought the PX4 would be a slight improvement because of the newer technology, but the opposite is true, it's horrendous.
No, a PX6 would be a bad choice. the 7862UIS option would be great but I see nothing which would fit in my car, and waiting for the RK3588 could last a while with the current chip troubles.
I'm not going to kill anybody, no troubles

So, if not reusing the MCU is not a problem for you...what about looking for a 7862UIS with a screen that has the same physical size as your current unit?
All the plastic fascias/stereo-fronts are made (most probably) by the same factory, and then distributed to different radio-manufacturers. Its a very low margin manufacturing business that only works if you do runs with thousands of units produced... is not a business large enough to have multiple providers. So, most probably you will be able to take the fascia of your PX4 and adapt it to any unit (MTC or FYT) as far as the screens are the same size
