[Q]3G wifi card replacement. Hardware modification? - G Tablet General

did anybody replace the wifi card with 3G or even 3G+GPS model? please post the guide.

WiFi for the gTablet is a chip soldered to the mainboard, not a plug-in card, therefore not easily replaced.

But you can add a 3G card (mini PCI-E) if you add a connector (and maybe some other stuff). There is a thread on "hardware replacement (with pics)" that talks more about this.

thank you for your reply. i just read that thread and realize there is no connector on our board. it is too hard to solder that connector on.

Solder connector is actually easy, what is not easy it is to add all other necessary components for connector to work....

you don't need to add all components. go get a 3g network card from http://cgi.ebay.com/Ericsson-F3307-...ultDomain_0&hash=item230b570b8d#ht_3087wt_905 and ask pershoot to compile a 3g support kernel for you.

Where would one plug such a card into the gTablet?

How about a USB 3g

Not working yet on G-Tab, IIRC.

Maybe somebody did take a driver for the modem 3g-of ZT-180 for our g-tablet? (sorry my english)

I don't think its as simple as that. In addition to compiling new kernel support, you would need to solder a mini pci-express connector onto the system board, and then find some way to connect a sim card reader to it. The *easiest* way to get 3G support is through a usb modem, but I don't think anyone has found one that works yet (probably because of lack of support within the kernel).

[Q] UART Access

[Posting in correct forum]
I was wondering if I can use the same headphone hack on the G2X to access UART as was published for the Atrix?
Furthermore, is it the same USB pinout to access NVFlash?
Thanks!

For your first question, no way to know but to try I don't see that it SHOULD cause any harm (but it's still at your own risk ).
For the second question, I don't see that it's relevant. We have a working NVFlash utility. Am I missing something else that you're wanting?

I actually don't have a G2X right now. I am looking to buy one, but only if I can get early UART messages since I plan on heavily modifying the kernel to the point where it will fail early in the beginning. Is there any other way to get early kernel messages from the device other than UART?
So NVFlash will work with just a regular micro USB cable? If that's the case, I'm happy
You can find the P999 (G2x) Service Manual at this thread:
http://forum.xda-developers.com/showthread.php?t=1037120
There is a system block diagram on page 37 that shows UART at the USB. It appears that the UART goes to the Qualcomm chip and not directly to the CPU, but I don't know if that's fine or not.
Page 257 tells us the MicroUSB IC is:
MAX14526DEEWP MUIC , ; , IC, Analog Multiplexer CSP
R/TP 20P MAXIM INTEGRATED PRODUCTS INC.

So if you can find information on that chip you can get to its UART.

For that I would ask faux123, morfic, or krylon. They probably have the most kernel development experience for the G2x right now (aside from TeamDouche anyway )
Edit: Missed the second half. Yup, nvflash works with stock USB cables. It's used commonly to directly flash the custom CWM recovery bootloader rather than use the update.zip method.

I looked through the service manual, thanks for the pointer! I couldn't find a datasheet for the MAX14526DEEWP, but I found the driver code in the kernel source published by LG.
It looks like writing '6' to /proc/driver/hmuic will turn on UART debugging through the USB port on the device. I'm still not sure what the pinout is for RX/TX, that'll require some further digging. Reference: kernel/drivers/star/star_muic.c:585
There's one more piece that I'm unsure of. It's the DP3T switch listed on page 181 of the service manual. I think MDM_UART_SW needs to be 0 and AP20_UART_SW needs to be 1 to pass the UART data from the processor to the MUIC. The AP20 GPIO is exposed in the code as STAR_AP20_UART_SW in kernel/arch/arm/mach-tegra/include/star_pinmux_definition.h
So, in theory, if I initialize the AP20_UART_SW GPIO correctly, and initialize the MUIC driver to "developer" mode early enough, I should get serial output directly from the Tegra
It appears, based on the news in this thread, that the headphone jack also does have some sort of data connection happening.

Hmm, yes it does. I'm guessing it's not UART, but rather some protocol they've defined and are using the mic input to transmit data to their app.

[Q] usb memory card reader ?

Hi!
i'm a photographer and would be please to directly read my photos on the touchpad with and usb memory card reader ... any project seen on that ?
Fred
I would also like to know about this.
SENT FROM MY DINC2 RUNNING CM7 overclocked to 1.6ghz
I'm also a photographer so this would be very useful for me. It'd be great to be able to backup an SD to the Touchopad when on location.
The other option I'm considering is an Eye-Fi SD card or two so I can wirelessly transfer images. It should work.

It's definitely possible, people are doing it.
It just requires several cables (one an OTG), an AC-powered USB hub and your time. I'd rather be able to just plug in one cable/device.
We have the port, just need the OS to use it correctly. As I understand it, USB is USB - data-wise. Maybe one of the talented PreWare devs can write a patch we can load eventually.

I'm assuming you want to connect something to the Xoom and have the Xoom in usb host mode.
Is your new cable a usbOTG cable? If so we can probably get it to work. If it is just a regular usb female to micro male cable it won't work, because OTG has a different pin configuration.

As I understood, I can't get it work, is there any other rom that I can get it work with?
If not, can u give me amazon link for one of the cable you have?
Otg has different pin, but I remember one guy made it work with making an installation file for motorola milestone which I have (with froyo), is there anyway like this to get it work? Or fake the pin ?

The link avobe is for a cable sold on ebay. You have to be a bit careful because some say OTG but they aren't. The official Motorola Camera Connection Kit is a small cable that is a proven OTG.
If you are rooted the Tiamat Hammerhead Rom or the Tachi kernel give USBOTG support.
There are also some free apps that help to mount//unmount the drive.

[Q] 3G dongle (e160e) Xoom Wifi ICS4.0.3

Hi
I've had a single sitting around for awhile and I've learnt that you can get a xoom to use this via a USB cable, I've found support for it on honeycomb but nothing about ics yet, is it too early.
Anyone know of any topics for this.
Thanks

I've never played with one, so I'm only going off what Ive read. Should be the same as the Ethernet dongles. Create the interface, register with dhcp if need be, etc. However, there is user-space work that needs to be done for all of these interface mods. Most people report limited functionality as many apps don't "see" the interface. So I believe there are some extra unknown steps. I'm gonna start a fresh thread on this topic because it seems to be a popular concept. I'll holla

Yeah- 'cause as we've discussed in private, what I'd like to be able to do is replace my internal LTE Mini-PCI modem with one of the HSDPA+ Mini-PCI modems I've got lying around, so when I travel overseas I can use my Xoom with native GSM 3G data.

LG has resolved the power issue, so it should. Recall that the N4 was released as USB OTG, but had to be backtracked when it was discovered there was no power. Fortunately,,cable and kernel tweaks by devs worked around the issue.

YAAAAY!!!
Looks like it should from the various log file leaks etc. My main reservation will be the ability to get ethernet working OTG like with the N7. Got this working with my Note2 after building the kernel modules myself - hopefully the N5 will be precompiled, or easy to create too.
Most Android phones at the moment support it so it would be weird if the N5 didn't support it

maybe for making it cheap xD
If the service manual that was leaked is accurate, the hardware will support USB OTG. There are a bunch of references in the manual (the Qualcomm power management IC has a VOUT_5VS_OTG output, a block diagram for the charging/USB area shows +5V0_OTG_OVP (over voltage protection), and there is a OTG enable line listed (OTG_EN)).
I didn't realize the N4 didn't support OTG (without a bit of a work around) until I came across this thread and did some reading about it.

That is a nifty device. I was going to sell my 64GB uSD card with my Note2 after I get the Nexus 5, but maybe I will hang on to it and get one those uSD adapters. It would be much easier to carry that uSD adapter with a 64GB card inside instead of an OTG cable and a thumb drive.

If the N5 is even loosely based on the LG G2 it will have USB OTG host. My G2 natively mounts mass storage devices via USB OTG.
Does any one have a link to a mirror of the N5 service manual?
