Edit: Counterfeit Rii i8 Keyboard touchpad...

Since I didn't find "Stick computer Mini-keyboard/mice" section in these forums I assume this is the best place for this... and since only certain dongles with with these TV sticks this is assumed in the correct section.
Okay I really like my MK808B, but got a... what seems to be called i8 Keyboard:
http://www.ebay.com/itm/400426715732
Keyboard SUCKS, touchpad SUCKS. When ~3ft it works... let's just say barely functional. Double-types characters, misses characters typed, touchpad barely functions. It is like the connection has no ACK, with a double-type here and there.
I am looking for a device that is rock solid that types when I type, and doesn't double key a single character, so am I limited to Bluetooth for something with an active connection (like TCP vs UPD)?!?!?!
I really want something like a presenter mouse with cursor keys, these would be required "up, down, left, right, back, home" for rock-solid: press it and it take the button.
I just don't want to keep buying trash hardware keyboards w/touchpad if someone knows one that works well.
I need like 10ft range, but bluetooth's 30" would be a better option.
Any input would be helpful, as I am at a loss, but I need something that works with these stick computers specifically, as kernels for these sticks do not work with all dongles...

What wireless k/b and pointing devices are you guys and gals using?

It looks like I MAY have a counterfeit/fake i8 keyboard, and this is the issue.
I bought a Bluetooth touchpad/keyboard combo, so we shall see...

Yeah I just got an i8 myself and it works fine at about 25ft. I also noticed there was some kind of anti counterfeit sticker/ serial number with scratch portion on the box when it arrived was there one on yours?

Nope!
I did see that sticker on some listings, so now I know what to look for, and the legit ones state "Genuine" or "All sellers should be authorized by Rii company. Dear customer, please ask seller to provide Rii authorization. If they can't provide, what's they sell is fake. "
I have been burned on razors (Gilette Fusion's are usually 30-50% cheaper on eBay), and people tried to burn me again, but I knew to include "genuine" in my search terms for those but after the 1st time, I knew what to look for on counterfeits of those. I thought these were just cheap k/boards, but I didn't know that there were good makes of them, with frauds out there.
The "Design" of the thing was so great, and the form looked so functional, I went ahead and bought a Legit one, just today... we shall see!

Crap, I bought another that states "Rii i8" in the description, title, and some of the images and sent a message when paying from paypal something along the lines of "If this isn't a legit Rii i8 go ahead and refund, but do not ship..." My eBay inbox had a message stating that it wasn't legit, and asked if I wanted them to ship anyway... COUNTERFEITING-WHORES-EVERYWHERE! I reported the listing as fraudulent! This is ridiculous!
If someone wants a LEGIT Rii* i8 Keyboard that functions, it appears that a good search on eBay appears to be 'Rii i8 "is fake"' without the single-quotes, but include the double-quotes as such:
Rii i8 "is fake"
"is fake" includes part of the description stating "All sellers should be authorized by Rii company. Dear customer, please ask seller to provide Rii authorization. If they can't provide, what's they sell is fake." and appears to work wonders. "is fake" would probably be a bad thing on illegitimate device descriptions, as it might make people google their issue, and end up here.
That seems to get a search for legit i8's done, and with only good results. eBay says that it has "0 results" but then appears to list what you are looking for...
What you are looking for is the COA in one of their pictures:

The counterfeits are even displaying legit images of legit products on their listing, here is an example of the second fake I bought, thinking it was a Rii i8:
I hope this helps someone that could be getting screwed, like I WAS...

On yours does it double-type characters all the time?
I just got a bluetooth keyboard and it too is double-typing characters, and ofter repeating characters more than 10 times with I hit a character once.

I just received the 'Rii mini One' keyboard. I had heard about the clones and what to look for in that particular keyboard to determine authenticity. I also made sure that the site I purchased from showed pictures of only the authentic Rii. It did me absolutely no good! Got the keyboard yesterday. The picture on the box was of the real thing, it had the authentication sticker on the box like you guys talk about, - at this point I'm one happy camper because ALL I've been getting from Amazon lately is either a clone or a not very well repackaged defective returned item that's supposed to be new! And then I opened the box and found a clone inside,... indicator lights in the wrong spot, no ' ® ' symbol by the Rii trademark, and headphone jack is faulty among other things. So, the point is that you can't go by the box, you have to examine the keyboard. I believe the box is original because it even has the large picture on the front of the real item with the LED indicator lights in the proper place.

hi, i have a wireless 2.4 ghz mini keyboard mouse that works fine. it's called H9, have shoulder buttons for touchpad, i got it from aliexpress for 9 bucks. no double input and it has backlight.http://www.aliexpress.com/item/Backlight-Keyboard-Rii-i8-2-4Ghz-Wireless-Qwerty-English-Keyboard-with-Touchpad-for-Mini-PC-Smart/32710810761.html?spm=2114.13010608.0.87.2rUwMg
don't trust the description !!! it's not RII I8plus like stated.

I5 Plus Smart Watch wristband, unboxing and review

Hi, I have xiaomi Mi Band 10 months and i´m looking for new wristband, working and cheap.
I decided to buy cheap wristband with OLED display, 7 days long working time and clever idea for charging.

Here is my unboxing and review....
https://www.youtube.com/watch?v=pa-oeHvBSzA

Thanks for the review, it's actually the first and only one I found in the whole web.
I got a question to ask though, what brand is it? It was mainly hard for me to find a review of this product also because it has no brand name but just a generic "i5 plus".

Hi, I think it's really only one review on the web - this.
Here I found a similar wristband, this one has a button, mine not. But manufacturer is probably the same, either app in her phone is zeroner too.
https://youtu.be/ykQUPBS3fSc

I found that video too but the brand name leads me to nowhere. However after further research I found out that the brand behind all these "i5" watches is "Iwown". Can you confirm me that (maybe by checking out your product box)? Thanks.

Hi, there is no manufacturer on the box, no brand name, only "smart bracelet".

Hi matey,
Does it display the contact name when someone is calling you in real time ?

Yes, but in my case it show only first 6-7 letters, no full name.

I'm gonna buy one, but have few more questions, how long does the battery last ? And how is the visibility in outdoor ?

5 days (5-7 days are declared), then I plug it to my USB 3port on notebook. After 25 minutes it was fully charged.
Visibility in outdoor is good, but strong direct sun could be problem - I can see time, but sometimes I need make shade by hand.

Thanks man for your feedback

I found another video on YT: https://www.youtube.com/watch?v=gX-RjWVrCvo
It's the same as yours but it has Iwown logo on the back, maybe yours is a replica of the replica of the Vidonn X5? Lol.

haha, it´s the same wristband
lwown has logo, but if you click to link under the video "where to buy", you will be redirect to the same page like "my" wristaband, gearbest - there is my text review too either app zeroner is the same.
vidonn 5 is similar wristband, but has a button and app is different.
here is review for vidonn x5 http://forum.xda-developers.com/general/accessories/review-vidonn-x5-smart-activity-tracker-t2814725
i dont like it, it lasts only 4 days and for time you must touch button, no gesture control...so i prefer cheaper "lwown" wristband

Good one, I didn't notice that it redirects to the same page.
I don't get, though, why one has logo and the other doesn't, but either way I trust in what you said and decided to order some, let's hope they will arrive soon and safe!

I hope that you will be satisfied, on the gearbest page were added other positive review.

Kernel sources for the Eonon GA1312

So, typos1 said I could get the kernel sources for the Eonon GA1312 if I asked in here. So I am doing just that.

Click to expand...
Click to collapse
As I ve said, theres no such thing as a "GA1312" - you have a Klyde MTCB/C unit, therefore you require the kernel sources for a Klyde unit, there are 4 types of MTCB/C unit - RK3066 high res, screen, RK3066 low res, RK3188 high res and RK3188 low res, it doesnt matter what your unit looks like on the outside or what seller you got it from. So using the seller's made up number when asking for help will get you few responses. And further to that, these units are made by at least 10 factories with only very very minor differences to some hardware and some software, to the extent that ROMs are interchangeable and even though the MCU firmware is not the same, the differences in MCU firmware are minimal. To all intents and purposes all versions from all manufacturers are virtually identical. Please read the wiki in my signature so you fully understand all about your head unit. To be certain what unit type you have please look in settings/about device.
You ll get more help if you simply rename your thread to "Kernel sources needed", because youre in the MTCB section, people will know youre talking about MTCB/C head unit kernel sources.
As far as I know the source has not been released, but I could be wrong there.
I take it youre intending on using a BT dongle ? Because you wont be able to do anything with the BT card on the unit which is entirely separate form Android.

You pestered me for one full page about asking for help (I never did). So now I created this post, just to show you - there is no way to fix this problem. The problem is unfixable.
I've used linux since 1998, I started compiling kernels in 1999. I started compiling my own kernels on my android-phones once I started using them (xperia mini pro).
I know there is no fix for my problem.
Now, stop pestering me and don't make assumptions. If I need help - I will make a clear and obvious cry for it. If I don't, then don't come running telling me to ask for help.
Now, kindly bug off.

I ve never "pestered" you, I simply tried to explain several times how things are with these units and yet youve completely ignored me and clearly STILL dont understand as can be seen by the use of "GA1312" in your thread title.
A fix may be possible if you can get a BT dongle working, I really cant remember whether someone has tried in the 3 years that these units have been out.
Youve already made a " a clear and obvious cry for" help by opening this thread, weeks after we last interacted, but it seems youre not really interested in getting help at all and your "clear and obvious cry for help" is actually crying wolf. Please stop wasting my time and your own.
Youve also broken forum rules by being abusive.

I cant see that anywhere in previous post where @typos1 suggests as such. I can see you stating problems with your "Eonon GA1312" which is correctly an MTCB unit; have you thought about listing the issues so others may help?

Take this bickering to private message please. This has no place in public forum.

Where to buy (just) the module like PX30, PX5 or PX6?

Hi all,
I'm currently trying to build a Rockchip based head unit from spare parts I got from other units and only missing the System On Module piece like a PX30, PX5 or PX6 board (see pic). Looked everywhere but cannot seem find them, only already mounted on motherboards or aren't for Android Head units. Checked the normal places like Amazon, eBay, AliExpress and Alibaba.
Any help would be greatly appreciated.

That's extremely expensive

You mean an MTCx module. They're readily available, just expensive.
Also, none of these Chinese units are Android auto. They're a hacked Chinese Android.

They are not Android auto. See/google certified units. These are a modified Android.
Android auto is basically screen mirroring, is that what you want.

Ah I see, this is what I suspected you'd say but was hoping for finding out something I didn't know. I have to politely disagree with you however. The purpose of pure Android head unit is to have a separate car computer rather than extension of a mobile phone. There are so many limitations with Android Auto unless of course you are prepared to pay big big money. The big upside with these Chinese units is that they offer a good base for modders like me to make vast improvements (hardware- and software-wise) at a very low cost, making these units outperform anything out there in the market in price ranges up to $2,000 I would say, especially when it comes to sound quality as there is nothing in this price range that even comes close to Viper4Android as an example. The value is even higher if you get one of those 8227L units as they are considerably cheaper than Rockchip-based ones.
The only reason I would choose Android Auto instead of real Android unit is if I run true surround sound in my car (Dolby, DRS etc) rather than stereo or extended stereo. Mainly because I think there are limitations that are beyond modding or at least on a fairly intermediate level.

Just clarifying, these units are NOT Android auto. They might come with a number of screen mirror apps such as zlink but are not Android Auto.
Yes you can install the Android auto app on your head unit, but that's still not Android Auto. Refer google for Android Auto info.
Seems pointless wanting to screen mirror to a device that directly runs an app from the playstore....
[Android Auto is a mobile app developed by Google to mirror features from an Android device, such as a smartphone, to a car's compatible in-dash information and entertainment head unit. Once an Android device is paired with the head unit, the system mirrors qualified apps from the device to the vehicle's display, with a simple, driver-friendly user interface. ]

Yeah okay I see what you're saying. I actually never used Android Auto app myself but I understand the value. And no, I don't understand either why anyone would be interested in mirror linking their phone to an Android Head unit.
I'm actually looking at buying another car and of course sound is one of the major areas that I look at, i.e how much I can improve, aftermarket options etc. Android Auto is supported by some newer car brands (I'm looking at BMW X6 or Mercedes AMG GLE 63 S) but normally is an upgrade option, quite an expensive one..

Curious if this is a decent head unit that I can use a custom rom with.

I purchased this unit and it will arrive tomorrow. I am familiar with android phone roms and custom recoveries but the head unit aspect seems a little different in a lot of regards.
Is this a decent unit for putting a custom rom on to enable viper4android, root apps, etc?

I got it installed and am checking out the MCU version and it says it is an MTCH. I haven't read anything about the H version, only MTCB and D. I know on Android phones the version numbers can cause a brick if they aren't for the same model. Is it the same in this case? Probably would help if I knew what an MCU was to begin with, or what MTCB, D, H, E, and H were even referring to....

MCU-MTCH has started to be used on the new boards, I've looked at 4pda and MTCH-HT there is no newer or older update yet. You probably have current. I do not recommend using an update other than MTCH-HT as you write you could get a brick. Try to write to the seller, maybe he will give you an update. And don't forget to share it with us. Why do you want to update the MCU, something is working wrong? If everything works for you, don't do the updates, usually no miracles will happen.

No I'm not actually interested in updating the MCU, I'm trying to figure out what custom rom would be compatible with my unit. On a typical android device if something is of a different version than what the device supports for that version of Android than you can get bricks, boot loops, or specific things that will no longer work, such as your radio unit for phones, Bluetooth, wifi, sensors, etc.. so I assumed that the MCU is the same? It has to match the specific hardware? I actually don't know what the MCU even is. I'm just going on an assumption and don't want to risk bricking my unit, or at the very least losing functionality. I even looked into rooting the PX6 series units but im not even sure how to go about that. Some say there is software for it, others say adb, and others say apps like KingRoot but I have never liked those apps as they tend to install crap you don't need or brick units.

The online costum-ROMs for our HU are these from the users Hal9k and malaysk.
You can also install the stock-ROMs from the yandex-folder I Linked above.
Your mcu is up to date and does not require an update

It is recommended that you run the stock ROM that comes on the head unit for a few weeks to make sure there are no issues with your new head unit. Plus you might find that the unit does everything you want it to do with the stock ROM. Installing a custom ROM just to "to have a custom ROM" is not recommended. May want to consider your reason(s) for installing the custom ROM.

You don't need custom ROMs - there are no true custom roms for these, they are modified base roms of one manufacturer
these basically mask/ workaround problems and may not be suitable for you headunit

Ahhh ok thank you. That actually help a lot. I was debating just spending a couple hundred more dollars and getting something like the Pioneer AVH-2400NEX. The display on this is a little washed out for my taste, and the actual unit itself is a couple millimeters to big to fit a standard double din dash kit. Apparently that's a typical thing with the Chinese head units that I didn't know about. The measurements tend to be off on them and are either to big or to small to fit correctly. I was thinking the Pioneer would be a bit snappier and have a much better screen. This Venku isn't bad by any means, it's pretty snappy and stuff, but its not quite what I was hoping for. Anybody happen to have one that can tell me what they think if the unit?

I have the same HU as you and I don't like the launcher that is installed. Looks like the HT-ROM.
So I can understand and understand if you want to change the ROM. In the yandex folder there are some stok ROMs from other manufacturers.

There are a lot of good alternative launcher apps available on Google Play and can be installed without changing ROMs. I use Car Launcher Pro (there is a free version too).
