Hey guys, so I know that there was a lot of false speculation about the possibility of altering the internal storage capacity of the G.
That was false, as the internal storage is actually an eMMC chip.
However, I bought a XT1032 model, with 16GB of internal storage, and, being a ruthlessly enthusiastic electronic engineer, I decided to take the matter of SD card support into my own hands.
I noticed, shortly after getting it, that my phone, being the single SIM variant, has an unused slot in the side, and, upon closer inspection, no important components around that area.
So it began; turning the unused SIM slot into a microSD slot.
I first went to PC World, and bought this tiny USB card reader:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I then stripped away all of the plastic, and all of the metal USB connector. I was left with this:
I then took the microSD slot from an old phone:
The above image shows two contacts in the top right corner which are pressed closed only when the microSD is present.
This is crucial to the operation of this mod, because it enables me to distinguish whether the SD is present or not (more on this later).
I then glued the card holder to the reader circuit board:
I used pliers and a scalpel to remove the unused SIM holder, and scrape an indent in the phone's pcb, to give more space to the reader circuit:
Finally, I soldered (VERY carefully) the relevant connections to the inside of the phone's connector, used a scalpel to cut away any obstructive plastic, and cut a copper sheet to fit over the SoC, RAM, eMMC, etc.:
And then put it all back together. I powered the phone up, and used a charger and a 2GB microSD to test everything, and hey presto, IT WORKS!
This mod takes advantage of the USB OTG function of the Moto G. My modifications, while extensive, are essentially an "Internal, Switch-able, OTG microSD Card Reader".
This is where the card holder contacts I mentioned earlier become important. The phone uses pin 4 of the USB connector to detect what is connected. A certain value of resistance between pin 4 and GND tell the phone what a connected device is. For charging the phone, or connecting it to a computer, pin 4 needs to be dealt with by the computer or charger. We cannot interfere with pin 4 in these two situations.
If we kept pin 4 low, the phone would try to constantly power the SD card reader, and so would not accept a charge, and would soon run out of battery. The solution is to only enable OTG when the microSD is present. This means that for charging, I take the SD out, the switch on the connector opens, letting pin 4 be controlled by the charger/computer. The phone can charge up, and when it's finished, I put the SD card back in, and OTG takes over again.
Neat huh?
Many thanks, and I hope you enjoyed reading!
to charge the device we could use a very little switch that short pin 4 to 5 (but needs to remember to uninstall SD in software first)

Thanks! I honestly hadn't seen your post, but my apologies for lack of originality.
I presume you soldered the microUSB connector internally then? That's what I'm going to do - very carefully!
Thanks to everyone else for their nice comments. More pictures of the finished project, and hopefully a video, will be up soon.

A quick question, does anyone know why USB OTG prevents deep sleep (More to the point, how I could disable this)?
It means that the battery usage when the screen is on is pretty much the same as usual, but when the screen is off, the battery usage is massive, as deep sleep isn't occurring.

Probably this is related to supplying power by phone to otg device. It would be really good improvement in next kernels to stop giving power to otg device when it is idle.
Currently, when u r copying some files, playing music from e.g. otg drive, when phone would go into deep sleep, transfer would be stopped because phone goes into deep sleep, so this also wouldn't be good approach...

Unfortunately, at the moment, a kernel module called 'msm_otg' is stopping the device from sleeping while the SD is inserted.
This means that I have to take the SD out when I'm not using the phone.
To solve this, I need to modify the kernel to allow deep sleep to occur. I'll post an update when I've solved this problem.
P.S; My username is actually Latin. It means: "The cunning of that which is hidden". It's about people's use of technology that they don't understand.

I'm wondering, if i use a ROM that has a Wakelock Blocker, like PAC-MAN, and use that feature to stop that OTG wakelock, will the OTG still work or not?
Sent from me using my tablet using an app.
The problem is that otg is not recognised as a system app or process, as it's controlled by the kernel, which is firmware.

Has anyone taken their Omnnia 7 apart yet to see if you can replace the microSD card with a higher capacity one?
It's been done on the HD7 so we need a brave volunteer to try the same on the Omnia.
This is really intriguing to me... if anyone does it please take lots of pics!
You're on the OMNIA 7 has a MicroSD slot?

No, not a normal slot.
In some mobile phones with windows 7, the MicroSD is hidden inside.
You cannot access without unscrewing, and it voids the warranty.
The phone must be taken apart into pieces to find the MicroSD, it is not one you just change for different music all the time!
We need a person to volunteer to take apart their phone!

exFAT disk format maybe?
I have an Omnia 7 testing device and I am willing to disassemble it. But I really don't know where to start with this. Seems that the phone can be disassembled only with special tools that I don't have...
Omnia must have a slot like the HD7?
Got this from a link (I am a new user: so can't post links yet: here's a goo.gl/Vi0e)
While the Omnia 7 has an microSD slot, it isn’t your run of the mill one. The microSD card that comes with the device is essentially locked to the device. If you remove the card, it will make the phone inoperable. I did read a tip that this may change later on, or if you swap cards and reformat then you have to suffer with losing your data, but that hasn’t been officially verified yet. Also someone will probably figure out a hack or way to copy the formatting scheme over to a new card to avoid losing your data, so don’t fret too much about this.
Just got delivery of Samsung Omnia 7.
I'm trying to open it up but I can only get access to 1 screw..the other ones are partially or fully obstructed!
@karthikraman - there is no card locking going on and upgrading memory is fully supported by MS. It just has its own special procedure and consequences. Too many tech writers have been reporting this as if it's some kind of hardware hack special to the HD7. Nonsense, as I said it's supported and designed to work that way.
Manufacturers have decided to hide the cards inside. Maybe they thought that was safer so that people didn’t swap in new cards and complain their phones had stopped working or, if they did the hard reset, that they had lost all their data.
Anyway, all we need to know is whether we can get to the SD card in the Omnia 7 or not. If we can the upgrade ought to work.

Well, I can post some pictures later, but generally, as hboos mentioned, the screwes under the battery cover are partially obstructed with the rest of the phones casing... Which means that before unscrewing these, the casing has to be somehow removed. There are no other screws on the phones body, so I guess the plastic top and bottom part of the phone has to be "unclicked" somehow. Or maybe we have to begin from the display, like with iPhone 3G for example...
OK, I have got it apart, but haven't found the SD card yet.
Where the slider is for the USB charger, use a small screwdriver & gently prise the plasic up (with the slider open), gently work your way around to get the complete cover off.
There you will find three screws, once these are rmoved the end will come off, after which you can slide the metal case off. You can then access all the screws.

Thanks Vince!
Taking it apart just now!
Just for clarity...to take the first bit off, open the usb slider and put a screw driver in to take off the plastic from the END of the phone... then everything is easy from there.
is it possible for the microsd card to be underneath the sim card slot or inside the area with the antennae?
Update:
I've pretty much dismantled the whole thing...just need to get the screen off and I can't seem to locate teh sd card.....it might be underneath the samsung sticker?
I have two photos but don\t knoiw hwo to put them up...they are 1.5 mb in size
Right guys,
After faffing around with this...the microSD card must be located just beneath the screen..unfortunately, I am unable to check for sure because the board has connections glued on to the sides for the power, camera and volume buttons..
what a downer

HTC, and maybe Motorola, is known to use microSD card for internal storage in various phones. Samsung, on the other hand, doesn't do that normally. All the Galaxy S phones have flash chips mounted directly on the circuit board. Samsung makes those flash chips, so it makes no sense for Samsung to use someone else's microSD cards.
Nice try and thanks for giving it a go.
Here's more info on the official position from MS:
http://windowsphonesecrets.com/2010/10/29/microsoft-speaks-on-micro-sd-and-windows-phone-storage-expansion/
I said on an HD7 thread that I think they are just being really careful and making sure they minimise potential problems - they don't need the launch to collapse with any Apple-antenna type bad press.
I think I've decided to go for an HD7 and will probably upgrade the memory once I've used up the 16GB.

Well on the bright side at least we wont have the memory failures prominent in SD-cards Charlie Kindel spoke about.
Okay. It seems that Blu Products isn't going to explain anything about the dock port on their Studio 5.3, so I am embarking on a project to reverse engineer it. I'll update my progress here.
Pictures of the dock port:

Pictures of the plug that fits it. It's the same 30-pin plug as found on the iPod and a bunch of other devices.
(Last 3 images from https://www.sparkfun.com/products/8295)
What I just ordered to work on this project:
(Again from https://www.sparkfun.com/products/8295)
Here's what I've figured out so far.
The cable from my iPod Nano 6th gen has pins 1, 15, 16, 23, 25 and 27. All others are missing. I haven't had time to analyze it all yet, but according to allpinouts.org, 1 is a ground, 15 and 16 are grounds and are tied together (internally on the iPod motherboard), 23 is USB +5v, and 25/27 are USB Data+/- OR, alternately, they are resistor-to-ground value-based signals.
My theory so far is that there is some internal resistance between the pins in this cable and other pins or ground; because plugging just the cable in--with it not being plugged into the USB port--disables the Blu's touchscreen and automatic screen rotation features and locks the screen in whatever position it's in when you plug in the cable. (Although interestingly, if you plug it in in landscape mode, you can use the screen rotation lock hardware button to put it back to portrait mode.) Plugging the other end of the cable into a USB port brings up the Recent Apps display (the thing that comes up when you hold the touchscreen home button down) and the phone says it's charging, but the touchscreen is still disabled. Not sure if it's actually charging or not; I'm gonna leave it plugged in for awhile and see. The phone does not show up as a new USB device when this (iPod) cable is plugged into the dock port.
Once I get the breakout board I'm gonna take the phone apart and see if I can trace where the pins in this dock port go. I'm also going to wire up a USB cable to the breakout board and see if I can get the phone to enumerate.
Hopefully I never toast my phone.
Edit for more pics from teardown:
Notice that this ribbon cable is 3 layers; those are little pieces of a paperclip holding them apart to show the layers.
It really looks like PDMI connector
If it IS a PDMI connector, would getting a usb-to-pdmi cable work to connect to the phone? I've never used pdmi. I know the Dell Streak has a pdmi port though.
You should open it to see what chips are used in that thing. That will help you a LOT to figure out what is going on...

Click to expand...
Click to collapse
I have both Dell Streak 5 and Blu Studio 5.3 and I can comfirm that the pdmi cable for the Streak does not fit in the Studio 5.3.
The ports on both are the same width and same number of pins but the Streak's pins are arranged on 2 wedges, for lack of a better term, whereas the Studio and ipods are 2 rows of pins on both sides of a single wedge. It's like the Streak has a female type port and the Studio/ipods have male type ports.
This could be some kind of dock connector that Blu has not released for our version. I've been doing some research on this phone to find the original recovery firmware and found that this exact phone is being sold under the following names:
Blu Studio 5.3
Texet TM-5200
Umeox X-Land / X-5
Pearl Simvalley SPX-5
On every "rebranded" listing I found they all had this port so it isn't just unique to the Blu. Also might try seeing if anything can be found for the MTK6573 chipset that would include this port. More info on this chipset here mediatek.com /en/Products/ featured_content.php?sn=2 {will have to copy / paste too new to post links yet}.
I've also found other indications through russian and chinese sites that this thing is being pushed in some countries as an iPhone knockoff with a custom "iOS" skin / launcher. Hard to tell for sure due to some things being lost in translation.
So to wrap it all up I would almost go for a crazy guess that this might be used on some of the "iPhone" knockoffs to fake as a 30-pin connector that may or may not actually work or only work for charging.
Its seems like its a docking port for a keyboard. I found this for Pearl Simvalley SPX-5 site found at http://www.pearl.de/a-PX3502-4072.shtml.
Now we know. I think I may import one of these to see if it works on the Blu as well. Might be disabled in the firmware though....
Just got the PodBreakout board. To the soldering station I go. Send good karma my way.
I took the entire thing apart. Everything is under full-board metal shields as can be seen from the recent post-op pic. (You can also see the breakout board.) My phone still works, so I'm not prepared to go pulling the shields off just to see what's under them. I think that the only things would be the MediaTek CPU and some RAM and Flash chips anyway. Everything else is pretty tightly integrated.
Puppeto if you get ahold of one of those keyboards please keep us updated.
Behold the wonders of voiding your warranty:
Ok here's what I've figured out so far.
1. Make sure if you take your phone apart that you reconnect all the connectors inside the phone, or else you'll spend an hour trying to figure out why the dock port won't work at all before realizing what you did.
2. Onward to real research, here's what's been found so far.
Connecting pin 15 to 16 disables the touchscreen, but there is a threshold that must be met that I haven't found yet. If the 2 pins are directly tied together the touchscreen is disabled, and if there's a 3k resistor between them it is, too. But if there's a 100k resistor inline it doesn't disable the touchscreen.
Pin 1 appears to be a ground pin.
Pin 16 is USB ground
Pin 23 is USB +5 volts
It DOES charge when just Pins 16 and 23 are connected. My next step is to find which pins are the USB Data +/-. As can be seen below, it's non-standard.
Connecting Pin 27 to ground presses the hardware multifunction button (bottom middle of the front panel)
Pin 6 to ground presses hardware power key
Pin 29 to ground presses hardware volume down key
Pin 28 to ground is an oddball. Connecting it to ground through a 10k resistor seems to start the music player AND press the hardware volume up key
Connecting pin 9 to ground with a resistor less than 4k causes a white screen followed by a black screen and the phone freezing until the battery is removed.
Audio
Pin 3 - Audio Ground
Pin 4 - Audio Right
Pin 5 - Audio Left
The audio pins appear to be connected to the same lines as the headphone jack, only they don't have the hardware external speaker disable (or if they do I haven't found it yet). Apparently, the headphone hardware triggers a software signal of some kind that disables the external speaker. I confirmed that this is the case by plugging in a set of headphones, in which case these lines still give the audio output but the external speaker is disabled. Apparently this is something that can be controlled from within Android, because there were some bug reports awhile back about the external speaker not disabling when headphones were plugged in. So we need to find (or maybe someone can write?) an app that does nothing but disable the external speaker while leaving the headphone line active.
No luck yet on getting USB working. Still hoping someone here can help me out with knowing how to monitor what's going on by using adb?
Puppeto any luck on that keyboard?
FYI received the keyboard, plugged it in, and YES it works. Didn't receive a prompt or anything when I plugged it in. I opened up a notepad app and just started typing away.
I do forewarn you though it is very cheaply made. Not something I would recommend anyone wasting their time or money on. I found it faster to just type on the screen.
Puppeto would you mind taking the keyboard apart and taking some high-res pictures of it? It would be very very helpful I think because it will have the data lines and possibly some other stuff
Please guys, is there no one trying to get flash working on this phone?
Adobe flash player worked great, however it need some mod
First install MX player then it will ask for special codec, so install them as recommended.
then you need to install UC browser ( try latest version )
Finally install flash 10.3.185.360_armv6.apk from xda

Its not the rom. If you are willing to try some other roms for this device (i cant find a blu rom either), search for either the umeox x3 original rom or the texet tm-5200 original rom. the umeox is in chinese and the texet is in russian but change the language in the options and change the launcher and everything should be fine. I have found the texet to be a little lighter and faster, however, i couldnt get any of the drivers to work for it. umeox uses the spx-5 drivers which windows is able to find easily. Im looking for a rom for the pearl simvalley spx-5 phone which is another clone and uses the same hardware, but i havent any luck yet. right now, though im using the umeox which also was able to be rooted with SOC and its working fine so far.. hope i could help

Ok, so i'm ordering a replacement digitizer and I figure this would be a good time to try this out.
As you all know, we Kindle Fire owners have neither expandable storage or bluetooth. Hashcode's new 3.0 kernel has the proper kernel modules/support for USB hosting. Instead of having to plug things in every time I need/want extra storage I figure that i'll try and hook up the stuff inside.
So here's what I figure i'll do when I get all the materials:
I already have a mini bluetooth USB dongle that i've disassembled.

}
And i'll be getting a mini USB microsd adapter that I can tear apart down to the same type of thing as the bluetooth dongle.
Now, the easy part is finding space to put them, there are a few gaps/spaces that I found for the bluetooth dongle, and placing the microsd adapter should be just as easy.
The hard part is getting the wiring all wired up on the inside, and this is where I need advice/input. Trying to solder the wires to the pins on the charge/USB port would be too hard and risky since they're so close.
I took apart one of my extra mini-b USB cables to use the pins to try and hook them up like that some way, but I don't have everything I need yet, so it's just a thought.
Ideas, advice, thoughts and/or comments?
Also, I will be documenting what i'm doing so that I can post a tutorial if I succeed.
I've also posted this in the Hardware Hacking subsection of the General board to see if they can give me any insight. http://forum.xda-developers.com/showthread.php?p=25212394
Many microSD slots have something like a contact that closes only if the microSD is inserted in, activating the reader. You can check this or buy a microSD slot that have this switch built in.

Are you referring on what the poster said in the other thread I made about the reader needing to be plugged in after the sd is inserted?
If so i'm not 100% sure that will be an issue. The sd will already be in when the Kindle starts up. If it is an issue I might use a small switch of some sort, but i'm hoping for a more elegant solution if the problem arises.
If u do this and open ur kindle than it will look scratched from sides

That's the issue i'm trying to solve. The charge port fits snuggly in a little slot. To solve that i'll probably have to grind that part back some to make a little space for the wires. I will probably use the pins from a USB cable and put some solder on the tip of each one to get them to stay. Then i'll connect some thin wires to the pins, and to the adapter.
I ordered them, but I don't have any more spare USB cables or the sd adapter yet, so I can't do a ton as of this moment.
I'm about to do a little experimenting, if I find a solution i'll take a pic to post.
Which why I'm thinking giving my kindle to my wife and buy a full pack tablet., although might be interesting to see if it work, or just buy those cheap made table with lower specs and which those micro SD card slot etc,... old smart phone would be a nice to get all your parts needed...anyway good luck to your project..
Hey, I'm tring to do this to my Galaxy Nexus as well, minus the bluetooth dongle. If you were able to solder the wires to the usb port, do you think you would be able to get the kindle to see the micro sd?
Are you not concerned that this will affect charging?

Charging wouldn't bother me too much as I can easily pick up another battery with an external charger. Now for the kindle, that might be a different story...
from my experience if you tap onto those pins and short 4&5 together, it would indeed mount on reboot!
but have you thought that if the usb port is in permanent otg mode how will you charge/use adb/and mount usb to pc?
for that i think you will need a switch to separate the otg short.
also at the minute i don't know if there would be enough power to be able to operate the flash drive tapping onto the out pins is the same as plugging in a otg cable/adaptor and as of yet most (if not all) flashdrives need additional power source.
that being said someone mentioned that linux double the safety limit for the max power draw, so i think that maybe some dev-god (hash) would need to alter something in the kernel to lower the safety threshold.
as you pointed out in previous post where to put all those wires
and switch?
not sure but the bluetooth could work but probably with the same issues as above .
hope this helps (i'm not trying to burst your bubble as i like a little hardware Modding myself) but i think you should put your efforts & skills into a slim useable adaptor or something, which pack's all those goodies but 1.can be removable and 2. if you f$+k up your soldering as i have lots on my otg adaptors then its not good bye mr kindle

I've got the wires soldered onto the pins no problem, I just can't get USB host to work at all, I haven't tested since build #6(I think)(I used some modules someone posted that they compiled) of Hashcode's kernel though. I know I didn't mess up soldering cause USB still works as well as charging, and I get a reading on a multimeter when I test the + & - leads.
I've thought of a solution for turning off USB host easily, all it requires is a magnet and a reed switch/s. Read below.
Also, my main goal is to get storage working, after that I might try bluetooth and/or gps over UART(read below)I've ordered about 10 different microsd adapters, some of which claim to need no power(confused me at first lol, I think they meant no external power), anyways, my point is microsd cards require very little power to run, so I think they'll work. If power is an issue I can just take a couple of resistors and such and power the adapter straight from the battery.
Other thread was created here, just want to keep all the threads up to date: http://forum.xda-developers.com/showthread.php?t=1632277

The UART modules are only an idea, the main problem with going that direction instead of USB host is the drivers the modules would need(They all usually come with generic ones, but they would need to be customized for Android). I have very limited code/coding knowledge so I would need alot of help or soeone to do that part completely. I was going to pm Hashcode for help if I decided to try out the UART modules. Also, i'm unsure if more than one module can be used at the same time.
Like I just posted in the thread i'm still waiting on some stuff to arrive to actually get started on the USB host attempt. I have the wires soldered to the USB/Charge port pins, but since I don't have the microsd adapter or any more spare cords to rip apart I can't go further. I ordered about 10 different mini microsd adapters to take apart and see which works out the best.
Other people have USB host working, so shouldn't be difficult. I've just never used USB host before so i'm not real sure of what to expect.
The only downside is that there needs to be a switch of some sort somewhere to disable USB host so that adb/storage will work. I'm trying to think of something a little more elegant that having a huge hole in the case with a switch protruding out of the side. I'm going to go searching for some solutions and a super small switch.
All the UART GPS modules I found when searching "uart gps module" on Google are mostly from India and are between $30-50ish, the receivers look to be about the size of a quarter.

I decided to look on Sparkfun and adafruit and i'm glad I did, it looks like they both have some modules, but I haven't looked around and dug through them yet.

All the optimism aside i'm not all too sure that we could get the GPS UART module to work. From what I see (First picture: http://forum.xda-developers.com/showthread.php?t=1471813) the UART output that Hashcode put into use only has two GNDs a TX and RX. The modules that I found all look like they need 8 connections. Adafruit has a nice pic of the connections labeled here: http://www.adafruit.com/products/746
If you're talking about microsd UART modules, as mentioned in the thread I created, someone made the point that it wouldn't make much sense because speeds would be way too low.

You have to remove the chip from your sim card and place it on your SD Card
Has anybody ever tried this method? As I think doing this could possibly damage your SIM card.
i tried to create this "sandwich" too, but if i had compared my first product with the very tiny slot, i have stopped development until now. A sandwich like this isn’t so necessary for me.
This is not my post, but you can see there some pics about the way you have to go then:

I suppose anything not strong enough will avoid the correct contact from the card reader. From my small experience (only made it twice) the SIM position is crucial and a slight misalignment is enough for malfunction.
So:
1 - You have to make the SIM really thin to fit the SIM tray with the microSD, thus "destroying" it for future reapplications.
2 - The microSD is easily reused, just by gently and patiently removing the SIM and glue remains. Also, no metal part from the microSD is harmed.
You can always ask for a SIM replacement or a twin card. I have 2 with the same number and I can do all there is to do with either one.
I don't care about destryoing my sim card it can be easly replaced, worry about microsdcard if I glue a sim card to it how can I remove it in future ? Supeglue is kinda strong
Has anyone had an real success with this? I've separated the SIM contact from the plastic backing and removed any excess. I've trimmed all excess from the SIM contact (so no overlap with the tray) and have temporally stuck the SIM contact to MicroSD card with double-sided stick tape but no matter what I do I cannot get the SIM tray to slide back into the phone because the combo of the MicoSD + SIM contact is too thick. I even tried it without double side tape to see if if would go in but still no joy. Anyone got any ideas because there's seemingly nothing left to remove from the SIM contact or MicorSD. BTW, I'm using Vodafone UK SIM and 64GB Samsung MicroSD.
yes it's working for 5 month now. it's really Hard to get the sandwich into the Phone but it works and can be removed. if anything except the sim chip is removed You have to glue it on the sd. all other isn't strong enough and is too fat. Small drop off glue is enough and the sim can be removed from sd with cutter knife. tested it and sim and sd still working fine... Bend the edges from the sim a little down before gluing it so they don't jam up in the Phone

OK, now I have a big problem. I glued the SIM to the MicroSD using a tiny bit of thinly spread glue and the SIM stuck fine. I then tried to install the MicroSD/SIM hybrid into the phone and it was very tight. I g and jiggled and it JUST went it in with a firm press. The phone recognises the SIM but can't see the MicroSD so I've come take it out and try again but the SIM tray is stuck inside the phone and will not come out. I thought about removing the rear casing to help with this but the screw holding the case is behind the lip of the SIM tray. I have no idea what to do next!!
Would really appreciate some help on this.

I actually managed to release the tray with pliers and a strong thin nail pushed very hard into the release hole. It came free by a fraction of a mm, just enough to get a modelling knife edge into it to prise it open.
I've measured a few other MicroSD's and there are differences in thickness by +/- 0.1mm, which may well be enough to stop the hybrid card going in altogether. My Vodafone UK SIM was also very very slightly domed, not absolutely 100% flat.
The upshot of this is that it's imperative to check that the combined thickness of your SIM plate and MicroSD card will go in happily. I actually tried them together into the tray without any adhesive whatsoever and even this felt a very tight fit. I figured I'd stick them together and see if I could waggle them in - no I couldn't, of course it was even tighter.
This is a precautionary heads-up for anyone who thinks this is a simple and easy solution. In principle it is, in reality it can be a huge pain in the ass. Lesson learned.
Just a place holder for now. I rec'd my test/sample unit today. I took it out of the box just long enough to snap a photo or 2 to send to a friend. Nothing detailed worth posting here yet. I'll try to take better photos this evening, and might even try to get wired into the truck.
Of note: It looks just like the NU/NR3001. Same screen size, same buttons. It also came with a dash cam with a dedicated harness/plug. I haven't investigated the underlying connection type (USB, Composite, etc).
Will post more details and clean up this OP as I do.
Thanks two-head/three-arms. Looking forward to it!
First look. I have a few software/language issues to solve before I put this in my truck, but here's a quick runthrough:
I can't watch properly at work but those Bonovo apps look very familiar.

Hey. It is not clear, and where a slot for a SIM card. Look on their website in China http://www.newsmy-car.com/product/showproduct.php?lang=cn&id=75
Thanks for posting. I am wondering if they packaged the main board in an NR housing as the new one is not yet ready, and this is a sample. Just a guess as the one on the web page looks a little different and it definitely needs a slot for a sim card. Seems like they made very little change to the MCU portion if the same code runs on it; stating that based on version number. Dash camera specific slot is of course new but all other cables are identical to the ones I received with my NR. If you get a chance please test USB behavior on shutdown. Thanks!

There is indeed a SIM slot inside. You have to void warranty to get to it though? I'm now starting to also wonder if this isn't the final chassis.
I'm also very frustrated in that the only USB Connection is on one of the small harnesses and it's USB-Female A. Which means I need an Male A to Male cable to connect to my computer. Since that is technically against USB Spec, I didn't have one of those. Started to cut a few cords apart and make one, but decided to just order one from Amazon instead. Will be here in a couple of days. Hopefully I can sideload Play services and get some real apps on here, check out ADB, etc.
I can't put this in my truck until I am able to load G-maps and/or Waze and G-play Music or Power amp, etc.

Definitely looks hacked together. The main board is much smaller than the NR one. I think they would take advantage by packaging in a smaller chassis. No heatsink on the one you have; the NR one is not adequate as is if you run all four channels at moderate to high volumes.
Does it really only have 1 GB RAM, as listed on the webpage?
Be careful with the USB you order. Several people have had issues with cables longer than 3ft. You should have gotten a second USB cable with it and too bad they did not give you the 5.1 cable (sticker shows it has the output).
hello, I am also curious. the Carpad 4 has really only 1 GB of RAM and 16 GB of internal space ?? For me to have 1 GB would be a total regression.

What I saw is a failure . The device really is not ready at all. And what they want from you? What is the test? Here it is necessary to refine the mind is still lots and lots. 1GB of RAM is not serious at all. My NU 1GB of memory and I want to buy a new unit with 2GB of RAM, 1GB is not too much and not enough.

Where do you think the SOC is? I think it must be on the same board as the sim (underneath the MCU board or on the underside) as the SOC they are using has built in 4g/Bluetooth/wifi and all the antennae are all originating off that board. I am guessing that black overhang off the back are the external 4g antennae?
This is my Carpad 4 . It has simcard slot in the unit. We need to open cover to insert simcard - this is so fun! And we have somethings more:
1- This unit haven't Chplay to install app from market; may be in final version they will update this. I have only head unit for tester
2 - xposed additions (one of the most interesting module for exposed framework on our car) will not work at all. So we can't use this exposed addition module to do something as carpad 3. We will ask Newsmy do keyeditor can function as addition xposed.
3 - Ram 1Gb - this is downgrade product from carpad 3
The good new is Camera has got verry good quantily (HD camera 720p or 1080P)

The 1GB seems to be the only real downside so far. But, that may or may not affect real world performance. I'm still trying to sort out a few things before I put it in the truck full time. Then I can see if the RAM degrades performance.
The camera additions are pretty neat, and I'm waiting to see how this 'New Yan' remote app works (I can't get logged in).
I cut their rear camera harness and tried to wire in my existing OEM rear cam (I REALLY don't want to run their camera to the back of my truck!), but that didn't work on my initial test. The front/DVR cam is pretty neat. I was able to sideload Waze, and will make another stab at sideloading Google Play services this weekend.
I'll take some more pics/videos when done.
I know some are dismissing this device due to the 1GB, but I'd suggest holding off on judgement. What myself and @ngochoangimsat have is an early engineering build. If we give them good feedback, the final product might be well worth having.

That's what I'm hoping. I still think the NR is a pretty great device with xdAuto on it (with the stock ROM I could never get it to stop reporting "Main activity has stopped".
Unrelated I am curious about the relationship between Bonovo and Newsmy. Is Bonovo a supplier to Newsmy. The MCU board on the 4 actually says Bonovo, not Newsmy!
Another test video:
I also came up with a really crazy idea. I was working on a friends NR5002 getting ready for his install next week. Realize that all the Nu/NR and Carpad4 chassis and screens, etc. should be interchangeable. I have an NU5002 with no android box to power it... and of course I prefer the 8" screen to the 7" universal so ......
Tearing them all down now.... Could be able to make a Carpad4 version of my NU5002
Well, crap. I broke it.
The 8" screen from NU5002 does work. The chassis parts are not quite as interchangeable as I had hoped. I could force it to work, but still had a few too many issues to solve, so I went to put it back together in original form. Unfortunately, the LCD ribbon connector is in a vary precarious spot and it evidently lifted away from the board at some point during my trials. I tried to superglue it back to the board, and can get video to display if I put just the right amount of pressure on the cable, but as soon as I let go, it quits.
Back to square one.

Very interesting, I too have a NU5002 and would love an 8" version. Is it still mostly empty with circuit boards on the bottom? This would help me as I need to modify the case and maybe remove the screen from the rest to make it fit in my car.
Software wise, is it lollipop with a kit kat base like I've seen other manufacturers do?
Syncing text from phone to head unit seems like a neat feature. Any idea of back porting it to previous units? Honestly that should already be implemented in Android natively.
