daml: you inspired me to order the same monitor as you after i did some research on lcd resolution in Android and then actually found the answer in the G-Tab forum.

http://xdaforums.com/showthread.php?t=864338&highlight=lcd+density

The first comment is wrong in the above thread, if you set lcd density lower you actually get a higher resolution images. I downloaded "LCD Density Changer" from market (from my nexus one since the paid version wasn't on my g-tab market and the paid version makes the change permanent - the free version works on the g-tab as well but with the wake-up from sleep slowdown a permanent solution is needed, and installing the paid version on the g-tab worked). On the current screen changing density from the stock 160 to 130 makes the image look 10 times better and even improves the viewing angle a bit. The quadrant scores were virtually the same ~2400 with higher rez. You can make the rez even higher, my guess is that with the LP101WH1-tlb1 you need to set it closer to 110 or 100 given that you got a stretched image.

p.s. i tested with TNT lite 3.1.0

if you are interested here is the developers description:

http://developer.android.com/guide/practices/screens_support.html

"The platform assumes that default resources are designed for proper display at the baseline screen density of "medium" (160)"

The g-tab is default set at 160 which means they didn't try to optimize. My nexus one and acer liquid are set at 240 which is pretty much optimum for the amount of pixels on those small screens (i reset nexus one to 230 and it looks a bit sharper).

The first pic (from nexus one sorry for slight blur) where everything is smaller is with density set at 130, the second is standard 160 density. The best focus is on the notification bar at top and you can see the icons look sharper at 130 (on the second picture the widget says 130 but that is the permanent setting, the temporary was set back to 160 on the second pic).

Has anyone noticed some flex on the back of the device? Around the top of the Viewsonic logo. Depending on the way I hold it I can hear creaks in the plastic...

Hi all,

I live a few towns over from Bliss Computing and pass the area everyday to and from work. Pending on how the roads/traffic look from all the snow we've gotten in the past few days, I may stop in tomorrow or Wednesday.

They have the LP101WH1-TLB1 in stock that daml used so may try this first. Are there any other's I should look into as well?

My biggest concern still is the 5+mm depth. I popped open the case tonight to see how everything fits, and there doesn't look like there's much buffer space as mentioned in this thread. It would be pretty easy to raise the LCD tray about 2mm (which sort of clamps it to the clear screen/front case) to accommodate the required thickness (may need some longer screws), but this would then raise the battery/boards and more than likely that back cover about 2mm. Then some fill trim would be needed to fill the gap around the edges as daml mentions as well which might not be all that bad. One concern with this is besides for the 4 corners screws, the covers clip to each other in several locations making the case nice and stiff, so I'd effectively be getting rid of these and relying only on the screws on the corners. Maybe I'll have the seal the edges with some carbon vinyl I should have left over to help make them stiff again...

Might not be all that bad, just trying to figure out if its worth it, and will the res/apps actually get cranked up with it(need to read up on that density app)?!?

I emailed Bliss Computers a few days ago about the availability of the LG panel, and they replied to me this morning saying they don't have that specific model.

I'm still awaiting replies from several other e-tailers and ebay sellers, but the general consensus seems that anyone that's selling this LG panel for less than $60 USD, is actually just selling a compatible/inferior panel.

I just want to confirm that this is true. I placed some wooden shims (those paint stirring sticks found at HomeDepot/Lowes) on top of the stock LCD to emulate a panel with ~5.6mm thickness. And there's no way the stock casing and stock screws have enough clearance to accommodate the thicker panel.
[G Tablet General] rothnic:
This doesn't change the output of the resolution, only the scaling of the interface components.

One thing to consider with the gap are the buttons. They rely on the closed case to keep them in place.
[G Tablet General] ray78:
That's funny, they emailed me back on Monday saying it was in stock so maybe someone ordered it. I didn't have the chance to go over today so hopefully will do so tomorrow.

I think we're on the same page about the case, but maybe I wasn't clear in my ramblings :)

I was going to put approx 2mm shims between the LCD tray and the front cover to raise it, which is the same effect as using those paint stirrers as a ~5.6mm thickness screen. Will probably need longer screws now to hold the LCD tray down.

Now the rear cover has risers where the 4 corner screws go that sit on the LCD tray. So if you raise the LCD tray, you automatically raise the rear cover the same distance, leaving that size crack around the unit, which disables the use of all of cover clips. Those 4 corners screws probably need to be longer now as well, and of course, that crack filled in some how.

If you cut those 4 rear cover risers down, assuming there is an extra ~2mm clearance in there where the batter and main boards are, which there doesn't look to be, then you'll disable the use of the corner screws without coming up with something else!

What about longer screws + black rubber gasket to fill the gap?
[G Tablet General] moli13:
Any update on your results? Have you taken video/pictures showing the viewing angles of the new screen?

thanks
[G Tablet General] floatpoo:
Have you looked at the high res breakdown pictures? (found here: link). I placed a ruler next to all the scans, so that should give you a frame of reference for determining the length of things.

There is an unsoldered "ANT2" connector next to the GPS socket. Maybe if someone could solder a connector similar to ANT1 (which is used for the wifi antenna), you would be able to get an active GPS antenna working?

As mentioned before, check out the high res breakdown pics. Hopefully there's enough for you to go by to answer this question. If there isn't, let me know and I can take pics of the questionable area you need.

I was poking around in the kernel source code, and there are definitely attributes in it that enable / disable external functionality like GPS (currently all disabled, obviously). So theoretically, if these attributes were enabled, then maybe the rest of the power pins will become enabled. I'm not an expert in Tegra architecture, but maybe some of the genuises in the VS Kernel Source thread could shed some light.

BGA soldering (especially for home DIYers) is extremely daunting. Barring experience or specialized equipment like you seem to have, I don't think the Average Joe can do it :(

Doesn't seem like you've been getting much interest in your endeavors, but if you can figure things out like true GPS functionality, you'd atleast make me a super happy camper :) Keep up the good work.
[G Tablet General] argentumomaha:
Does anybody have a chance to see a Malata SMB-A1002 with the optional GPS/3G module installed? It seems to be identical to the GTab so if we get a photo of the internals we will know for sure what module works 100% in the GTab.

w w w .malata.com/en/product_detail.aspx?classid=661&id=92

(BTW... I am new to Android, tablets, etc. and I've just had to return my GTab due to a defective MicroSD port (card pops out randomly). I've already ordered a new GTab that should arrive next week. )
[G Tablet General] duchski:
I am also very interested in GPS and 3G GSM unit. I suspect the Chinese 3G card would be CDMA but there has to be a compatible GSM unit out there as well... I am going to search FCC website which proved to be na an invaluable source of commercial espionage before. Hopefully Malatas unit makers applied for FCC ID for their device....

You should look at the nook color. Pretty capable little device with good devs behind it. A little smaller package with a really nice screen.

it might be a decent reader, but its single core 800MHz won't even handle Flash.
[G Tablet General] rcgabriel:
Hey daml, just wanted to touch base and see if you wanted to hack on this a bit more. I know how to change the resolution of the framebuffer device now that I've been kernel hacking and building boot images for a few days.

As far as I can figure, there are two things that need to be done. First, the framebuffer resolution which needs to be set, either in the kernel (hardcoded - see .width and .height in tegra-fb.c in drivers/video/tegra in the kernel source, this is bad but simple if you've got a working kernel build environment) or via bootargs in the boot image.

To do it by bootargs, you just need a breakdown of a working boot image for your ROM and then to repack it with a command roughly like this:

mkbootimg --cmdline 'bootargs' --kernel zImage --ramdisk boot.img-ramdisk.cpio.gz -o boot-highres.img

The issue is I can't figure out what the bootargs are supposed to be to control the framebuffer height and width.

I'm sure a more experienced kernel hacker than me will be able to trace through what goes on in arch/arm/mach-tegra/nvos/nvos.c with NvOsBootArgGet and explain what the exact bootarg arguments for the framebuffer width and height is supposed to be.

The last step (possibly) is the touchscreen driver. This may require some source code modifications. In arch/arm/mach-tegra/odm_kit/platform/touch/at168, there are several references to XMaxPosition=1024 and YMaxPosition=600. I'm guessing all those need to be changed to your appropriate resolution to make things work properly. A less hacky thing would be to make the touchscreen driver read boot args like the framebuffer driver so they could both be controlled the proper way.

Just my thoughts... I'd love to get a nice LCD in my G Tablet if you get this working well. :)

I have a zpad with 3G module and it is just a standard Sony-Ericsson WWAN module as used in laptops (did not write down the number though)
[G Tablet General] teknikk7:
That's because it's running 2.1 with the Nook software as overhead running in the background.

Once a vanilla 2.2 ROM comes out, flash will run fine. It has the same GPU as the Droid X.

Is it possible to obtain a replacement charging port? My tab was plugged in when my dog ran strait into the cord and the sudden pull was hard enough to loosen the port and then it completely broke off. Now I have a useless $400.00 POS!
[G Tablet General] tyy10002:
Just a thought,have youtried to charge it through a charging pad,i saw a demo in bestbuy that you can place your phone, camera on top of it and they will be charged without plugin. It costs around $30 dollars.
[G Tablet General] jfholijr:
hmm, I'll consider that. Thanks.
[G Tablet General] pmcnano:
I would love internal pics of your device! IF possible, thanks man!
[G Tablet General] jmdearras:
charging pads require special batteries or circuitry on the device to work. I do not think the G-Pad has any support for them.
[G Tablet General] mystkrh:
I second that! Love to see what we need to do. I'm sure some compoments are missing on the main board. As far as the ram it looks like i'll be able to do it I'm gonna order the correct fitting for our rework station at work and get some ram chips.
[G Tablet General] mystkrh:
Ya looks like it will fit just fine.

Correct I have the correct connectors and coaxial cable looking into what GPS antenna would be best.

Its more of i need to open mine up and probe around. Also need some software help from people to make sure these items are "turned on"

ya same as above I need help with the software >.< before i pull it apart and probe around while its on.

Ya my first few attempts on a practice broad with the right equipment didn't go so well lol...

I know I thought more people would be interested in adding GPS or the PCI-E slot but i guess not. I think the wife is going to let me keep it so I'm gonna open her up as soon as i figure out what to buy her for an ereader, she wants something lighter but i cant seem to pull the trigger on anything that doesn't have the tegra 2 in it.
[G Tablet General] theindependent:
I'm greatly interested in this, especially when it comes to the GPS. Perhaps not enough people are aware that this is being considered; I can't imagine there wouldn't be a lot of people interested in it.
[G Tablet General] anlog:
You can get a bluetooth gps receiver on ebay for under $40. It works perfectly, and there is no risk of damaging your motherboard like with the internal option. I think most people are going the external route.
[G Tablet General] theindependent:
I'm pretty fearless about doing hardware mods (primarily in game consoles and smaller electronics) as long as I have instructions and part lists in front of me. I'm just not the type to be the first one to do it. ;)
[G Tablet General] floatpoo:
Could you link me a specific model that's known to work?

I would still prefer an internal solution though. As its one less thing to carry around, and probably less power consumption since bluetooth is a power hog.
[G Tablet General] rosco_pc:
I had it open to repair/re-assemble the charger connector, which broke when it fell while charging. It is working again, but I'm not that happy with it and I'm looking for a new connector. When I find it I will have it open again and I can make pictures. Not sure though when that will happen, as I'm living in China and my knowledge of the language is limited, while my normal translators' knowledge of electronics is limited :p. So it might take a while to find the connector.

(What I remember though comparing the motherboard with the pictures in the first post is that the layout has been changed: at least the mini PCI-E port is now rotated 90 degrees)
[G Tablet General] rosco_pc:
I had a similar problem when my Zpad fell while charging. If the connector just came off, it is very easy to re-solder it: first clean the pads with some solder wick, apply new solder and put it back. There is very little solder on the original board that's why it is coming off soo easy.

Mine completely dis-integrated and I used some '10 second' glue to get it back together before I soldered it back on. It works, but I would sleep better if I found a new connector. I'm looking into this and will post my findings (but I'm living in China while not mastering the language so it might take awhile)
[G Tablet General] lifeisfun:
I would love to find internal GPS as well but not sure where to start. I'm not afraid to solder since I soldered couple years ago with great success mini PCI card connector to my Vaio laptop to be able install internal WIFI card :)
[G Tablet General] MikeM:
Hi, just wondering which bluetooth GPS has been found to work the best? I was interested in what app (google maps?) is being used with the GPS and does it need to be tethered to your phone for this to function?

I think we were talking about it in this thread so I will say it here. Has anyone tought of trying to put the 10.1 inch LED screen of the new Acer Aspire One net books?
[G Tablet General] anlog:
I use an external GPS receiver made by Holux. They charge via USB and have a small battery in them. You pair them like a normal Bluetooth device, then you install bluegps4droid and enable the translation layer with the app. Then, apps like Maps work fine (just make sure you enable the GPS option in system settings).

I run Vegan beta 5.1, so I'm not sure if this works the same on any of the tnt builds.
[G Tablet General] mystkrh:
What model do you have, is it the 1GB? Also where did you buy it? I'm gonna open mine up in a bit. I'll let you know what it looks like, but the model number is UPC300-2.2 what is your?

floatpoo what model # is yours you took pics of?
[G Tablet General] yzf600:
I use a Qstarz BT-1000 with the bluegps4droid app. Works quite well. I even accidentally washed the bt-1000 once and it still works perfectly.

Without looking into chip data sheets, I would think that bluetooth radio won't drain the battery any faster than an internal GPS module.
[G Tablet General] jfholijr:
One connector snapped in half so there is no way to solder it back together. The other 4 look possible to reconnect. Thanks!
[G Tablet General] rosco_pc:
The connector looks a bit like this:

1 2
(plug insert, front of motherboard)
3 4 5

3 is the tip and connected to the 12V power rail

1, 2, 4 and 5 are all connected connected together to GND (2 and 5 are a metal band over the actual connector which is mainly used to keep if firmly in place).

As long as the tip connection (3) is not broken off you should still be good to go. It is possible to solder a small wire to the tip as the metal is exposed on the back side, but this is not that easy.
[G Tablet General] jfholijr:
Ok this gives me some hope. From your description the #2 is snapped clean. The other ones still have enough likely to connect with. Thanks!!!

I am using APNdroid app for switching data connection from WIFI to 3G. However, I need to restart the phone every time to make it work.

Is this normal ? or Is there anyway we can fix it? I have searched through all the threads but didn't get much info.

Your help is much appreciated.
[Galaxy S I9000 General] Frostshock:
Not the answer to your question, but if you turn off 3G *only* when you turn on Wi-Fi, you don't have to do anything. While connected to Wi-Fi the data connection isn't on.
[Galaxy S I9000 General] Mortify1:
If you leave 3G on, Wifi (when enabled and connected) will disable 3G. Also superpower (in the app store) will turn off wifi and 3g when the screen is off. I also recommend Power Control Plus which provides a widget in which you can customize each button and toggle 3G and Wifi on the fly.
[Galaxy S I9000 General] netags:
Thanks for the replies guys...To be more specific on the problem , I don't have any issue while I am on wifi its only when I switch to 3G...i tried beautiful widgets also ...looks like the problem is with phone rather than app

Have anyone compiled psfreedom for new 2.6.32 kernel? Cant upgrade to 2.2 because of it. I would try it myself, but i newbie and need step by step manual;p
[Legend Android Development] gwon:
This is a development community. Try not to fly off the rails when someone asks about PSFreedom. In it's base form it's not a piracy application. No more so than rooting an Android device is. Sure it can be used for nefarious purposes, but why assume everyone on a developers forum who's interested in PSFreedom is a pirate?
[Legend Android Development] TheGrammarFreak:
Language like that is not appreciated, nor is it allowed
[Legend Android Development] Bravounet:
It is actually a good question regarding a new PSFreedom, an updated one for the new Kernel?

Maybe even as for the PsfMod, directly from the Recovery?

[Legend Android Development] warpout:
Well if i understood your question correct, you need rooted phone.

Easyest way to manage roms and update zips is clockword mod. Search Clockwork rom manger in market and install. Copy your update zip to sdcard, lreboot to recovery via rom manager, make nandroid backup then install zip and test. You can revert all changes.

Is your psfmod for 2.2?
[Legend Android Development] Bravounet:
Guys!! Two weeks I've been trying to create my own psfMod for HTC Legend, with the Klutsh's Howto ... And I am still nowhere!! :( TWO WEEKS!! lol!

Did any of you create a working img file succesfully?

I received some help from Klutsh and some other guys on his blog, unfortunately I am such a noob that I can't manage to do it right yet...

Any chance to get some help from here?

[Legend Android Development] gwon:
I plan on working on this. I've been holding off for Cyanogen to release stable for the Legend, so I have an easy starting off point for a guide - and I'll be doing less flashing/messing with nightlies.

I've still go an old TouchPro I'm using just for psf at the moment.

So the sooner we see CM6 stable, the sooner I'll get cracking on this.

What's going on with this? Where's the hold up? What has already been done?
[Legend Android Development] Bravounet:
BlaY0, actually, it was done, yes...

However ,there were not updates of it.

No possibility to use last payloads and other possibilities.

As per Klutsh's psfMod, it is possible to get the PSFreedom directly from the recovery, and then you can use the bin you want (put in your SD Card) : you just have to reboot then and can use your phone as usual.

So far, we lost Wifi and SD card access, we had to restore boot etc... Quite "restrictive" (compared to what is developed for Desire, Hero, and many other devices...)
[Legend Android Development] BlaY0:
No, I mean what has been done in terms of compiling module for new kernel?
[Legend Android Development] Bravounet:
Ho sorry! lol!

Then I am not sure I understand your question: What have I done so far that is not working, or in general? (English not native language, plus noob regarding kernels, compile, linux, development, ... Everything lol! Well you understand, right?)
[Legend Android Development] BlaY0:
Actually I'm referring my question to the subject (psfreedom+new kernel). I know that it is working with old kernel so it is working from recovery mode too. But I need to know what has been done concerning new kernel. Where's the problem? I'm asking coz I don't want to reinvent the wheel.
