No this wont work on the S18 tab. But yes if you replace the wireless realtek module and for example connect a hub to those pins and if android has the firmware you could connect more devices to the hub. Not sure if this will work through.

But really nice let me know some progress it indeed makes a huge different in use usability, i also replaced the battery with a 1800mah ion battery from a dead tom tom system(broken display), that had the same voltage(3.7) but the battery was dead so i had to put back the default one since i didn't had anything else that did fit in this tiny little tab haha.

Sorry for the quite slow response.

So is it possible to connect a game controller through the OTG + Power cable?
[Hardware Hacking General] NiTrOwow:
Please see the image of the soc. It does not have OTG on default. You have to got the datasheet and solder a OTG port on the soc itself.

That's actually the only thing that sucks about this device. No OTG, out of the box and no soc datasheet. Limilted support to all of the internal stuff itself. Is what makes it less fun for most of us. We are no pro's or people who are really good in reserving without a little bit of documentation or help. I would be glad if JXD would release more stuff about this device so more people can take a look at it and have fun with it in a diffrent way because the device itself it pretty useless out of the box in my opinion.
[Hardware Hacking General] Bizen-Ya:
As i already said Otg is working fine on mine ....

I have sucessfully used my s18 with a USB GPS + powered USB otg cable and usbgps4 droid :)
[Hardware Hacking General] NiTrOwow:
So you're saying that otg worked on your S18-03-XXXX device?

Strange i still did not had time to check it yet. And is also is strange because manufacturer does not say it had any. The soc is capable of 3 otg devices on the host but those aren't connected following all the technical details i read on their website and other re-seller's website. If you pull the device brand new out of the box and connect a otg device it should not work according to the manuals and details on their website, or they changed the pcb design and newer version has this feature enabled.. Can you post your model number?
[Hardware Hacking General] Frank Blah:
Otg works with external power

I hope this is no considered spamming, as I posted same info on other thread.

I have s18-03-201305-4GB-01748.

I guess they are not listing device as otg capable because device is not delivering any power to otg devices, so you need always power injecting cable. Otherwise device is not anyway restricted. Actually firmware has quite extensive hardware support as you can see by browsing driver folders on device.

I registered just to tell you that otg works perfectly with power injecting cable. Tested 2 TB NTFS drive and apple usb - Ethernet dongle. Both work well. Also you can use this device as WiFi ap with Ethernet dongle. I am planning to use this as portable server. I just hope somebody gets interested making updated firmware.

I may be repeating but I say once more. There is no need to do any hardware hacking to get otg working. Just get power injecting USB cable. You might have to put WiFi off and back on to get your USB device connected. I think this triggers device initialization.
[Hardware Hacking General] Lemzy:
Thanks Frank and Nitrow.
[Hardware Hacking General] Renate:
Yes, don't give up too quickly when testing Host mode on USB ports.

They might have no charge pump, an inadequate charge pump or inadequate capacitance for inrush current.

You usually will need an OTG adapter to ground the ID pin.

A power splitter cord will work, but you can't usually find one locally.

I use a "back-powering" hub.

That's a cheapy hub that has the protection diode bypassed.

Some really cheap hubs already have it shorted.

See: http://xdaforums.com/showpost.php?p=25639514&postcount=8

Try a keyboard first because they draw minimal current and they have a simple driver.

Some flash drives and GPS units are real current hogs.
[Hardware Hacking General] NiTrOwow:
Yes but i wanted to make a dedicated otg connected hard-wired to the print. but those connections (pins) on the board are too small and i can still not find a soc datasheet for the rockchip. I searched on the entire internet. It still isn't there...
[Hardware Hacking General] Renate:
Step one is to get USB host mode working any way you can.

Then you can discuss hacking it internally.

The other USB ports may be internally hubbed and not do host mode.

They may not have Id connections and you'd have to hack the driver/issue device commands.
[Hardware Hacking General] NiTrOwow:
That's not the problem since it is already reported to work on never soc, i only need datasheet and chip pin-out.

[Hardware Hacking General] ebsbow:
Did any of you try to run this without an battery in the unit. So only on adapter?

I am thinking of using one as an dedicated clock.

I also want to point out that there are two versions of this device for those that don't know this.
[Hardware Hacking General] NiTrOwow:
Not sure but i can try it for you, i am not making use of the device anyway.

I'll update this or pm you the results.

the device does not work without battery but my device is showing strange things. I have dropped my old and crumpy htc sensation battery in it now. And removed the speaker and added a SWITCH between the battery.

The protection ic was burned because there was a little bit of soldering oil on the pcb and it did not went good. Now its cracky but still works. However on battery it shows like its charging on AC adapter. Fail. Total fail. Anyway i will drop it in my router usb and switch off the internal battery. So i know for sure that it will not burn down my house.

Btw if you ever need more battery power, here is a simple but good working way

Its 40 pin 16:9 480x272

ZBH043GT-10

http://detail.1688.com/offer/1202016142.html

Model NO.:

Those are universal i think it doesn't really matter as long as they have 40 pins and the same size. You can contact the seller. And ask him. In theory they should all fit actually the only problem is idk what has changed in the older and newer batches.

Btw if you maybe wait a little bit you can maybe buy my screen(ZBH043GT-12 V1). My S18 is bricked so....

I finally got mine from Ebay after being lost in the postal system for quite a while.

Have done some software testing on it and it works with the Crestron software as needed.

I just tried it without battery connected and it works fine without. Next step is drawing a new chassis for it and print it out so it can be usen in place of a light switch and powered over ethernet.

I wonder if I can swap out the internal wifi with a usb cable driven ethernet board instead.
[Hardware Hacking General] NiTrOwow:
That's odd. What model/version do you have? Mine doesn't work without battery and keeps in the battery charging animation :(

This is the reason why i made this topic. But nobody can help, maybe its just the firmware or rom that has been changed, i would appreciate it if you could post more info about your device.

And yes you can replace the wifi module what is usb connected with another module that is android compatible and usb. That's most likely possible according to the rockchip specifications.

Btw this is fun to try out on your device.

[Hardware Hacking General] ebsbow:
I fear if you leave it running without battery it will burnout eventually. I tried it myself with an

other device I turned into an dedicated clock and the components are not made to withstand an

direct current for an long time. Couple of months tops.

You will need to put some kind of resister in between or keep the battery and use a timer to interrupt the current.
[Hardware Hacking General] NiTrOwow:
Indeed. They run at lower current and if you supply the board with just what it needs it will eventually end up dead. I believe if you have a good protection ic and place it between the board and the current that comes from a decent adapter feeding it that it will run much longer without dying so quickly. And im not sure what power ratings the device uses. But i guess its under 3vdc and a few mAh..

[Galaxy Note 10.1 Q&A, Help & Troubleshooting] PremiumMediocre:
I've noticed something strange. I suspect it is a software issue but I'd like to know if anyone else experiences it. When I make the s-pen approach the screen, the moment the tablet displays the gray "hovering" dot, it sometimes also makes a phantom tap.

Here is a video showing the problem: https://dl.dropboxusercontent.com/u/21246716/2013-04-28 00.27.41.mp4

In the video I'm hovering the pen in the app "Papyrus" with the eraser selected. Notice that no phantom taps are occurring if I move the pen even closer. It's "Pen too far away to register" ---"phantom taps" ---"Normal hovering" ---"real tap"

I'm using Android Revolution HD 6.0 on a n8010, with no special kernel.

Anyone else? I thought the pen could only "tap" when something touched the tip.

EDITED: Added video and removed the erroneous conclusion that it was only GUI related.
[Galaxy Note 10.1 Q&A, Help & Troubleshooting] PremiumMediocre:
After a bit more experimentation, I now see it is not gui specific. The touch is just so slight I couldn't see the resulting little lines. The strange behavior has the following characteristics:

It only happens in some areas, mostly I notice it in the corners.

It only happens when the tablet first detects the spen. When you move the pen even closer, no phantoms taps will register. This is what makes me think it is software related. I could be wrong.

You might just be in a refarm area without LTE.
[One (M7) Q&A, Help & Troubleshooting] Prod1702:
It most likely means you are not in a LTE area. 3G is UMTS and H HSPA+. I am sure if it was LTE you would see LTE or 4G on the screen. Run speed test and go to the settings menu and see what connection you are getting. It will tell you if it is one of the top 3. I do not think LTE is in Chicago yet for T-Mo. Also T-Mo changes the 3G/H with a 4G logo to make you think the phone is 100% of the time in 4G mode, it isn't. during sleep/deep sleep the phone goes into 3G (UMTS) to save battery.

Tmobile's LTE is Band IV 1700, no?

The unlocked developer's edition DOES NOT support that signal.

Am I mistaken?

Furthermore, if I'm not mistaken about this too, I believe the dev edition only supports Tmobile's HSPA 21 MB/s. It doesn't even support HSPA+ 42 MB/s.

Please correct me if I'm wrong? What will the refarming do?
[One (M7) Q&A, Help & Troubleshooting] Fromako:
It seems to be true that the dev edition will only do 21Mb/s and only where 1900 has been refarmed in regards to HSPA. It DOES support T-Mobile LTE though which is listed as AWS (1700/2100 bands) in the tech specs.
[One (M7) Q&A, Help & Troubleshooting] onthecouchagain:
I thought Tmobile LTE is only 1700, which isn't listed from HTC's website of the Dev edition:

Compatible on these frequencies:

HSPA/WCDMA: 850/1900/2100 MHz

GSM/GPRS/EDGE: 850/900/1800/1900 MHz

LTE: 700/850/AWS/1900 MHz (US)

But you also said 2100 which is listed. Is 2100 also LTE? I thought 2100 was only HSPA+? If it is LTE, why isn't it in the LTE category from the website?

All genuine questions. I'm confused.
[One (M7) Q&A, Help & Troubleshooting] Fromako:
I won't claim to be an expert on radio frequencies but it I would propose that there's nothing stopping a radio from being capable of picking up two different formats at the same frequency (at separate times). It just depends which format is broadcast at a given frequency in the area.
[One (M7) Q&A, Help & Troubleshooting] GuestK00156:
AWS is 1700/2100. TMO uses 1700 for up or down ( i can remember which) and 2100 for the other. 3G and HSPA wont work unless you are in a refarmed area on the dev edition. As someone said previously, "H" should be LTE since Chicago and suburbs have both LTE and have been refarmed. I have a dev edition and will be switching to TMO next month, and I live in Chicago as well. Im hoping that someone will get AWS frequencies unlocked on the dev edition. In the mean time:

OP try the following-

Flash a tmo stock rom and see what it gives you for signal. It should show LTE instead of H, but no difference in speed.

I'm considering this too. Are you doing it for the LTE support?

I would much rather keep my dev edition, but if it's not going to get LTE, that may sway me toward the Tmobile version also. Is that why you're doing it?

[One (M7) Q&A, Help & Troubleshooting] thewhitedemon:
onthecouchagain, you gotta actually read man. AWS IS T-Mobile LTE. AWS 1900 doesn't mean anything. Go back and read the specs for the developer edition, it says LTE support bands are 700/850/AWS/1900. See how the third item there is AWS. AWS is the band (or more specifically set of bands) that run T-Mobile LTE. And as numerous people on this thread have already reported, the developer edition works on T-Mobile LTE. The only thing the developer edition doesn't support is UTMS 1700, which means if you don't live in a refarmed 1900 MHZ area OR you don't live in an area where T-Mobile has LTE live, then you'll only get edge speeds and won't pick up HSPA+ on the 1700 mhz band.

I am anxiously awaiting the release of the black at&t htc one. I love the phone in black, but not so much in white/silver. Usually, I would just be patient and wait for it to be released, but I've applied for the trade in offer and qualified for $100 off, which I don't really want to miss out on just because of the color. The offer requires you to buy the phone before April 30th, in just 3 days.

I know it's coming at some point, but none of the At&t stores can tell me when. Sprint already has it (as far as I can tell), and I'm honestly a bit mad at At&t and HTC for not getting their act together. I don't want to buy the white one now and regret it later when the black one comes out, but I don't want to miss out on the offer and let $100 fly...

Can anyone help me figure out what to do?

I purchased my silver One at Best Buy. They have a 15 day return and exchange period. If the black version gets released within 15 days, you could exchange it. Also, if you have a Reward Zone card with them, you have 60 days to exchange it. That's what I'm doing. Bought the silver version to hold me over until they get the black One in. As far as the $100 credit, this wouldn't help. However, Walmart has the One for $149. Best Buy price matches phone's on a case-by-case basis so you could at least get $50 off. Just my 2 cents. Good luck.
