[Q] Touchscreen not working!! - G Tablet General

Last night my touchscreen went down and since I am a noob I have no idea what to do. Went through some threads briefly, but need to head out for work and was wondering if anyone here knows what I can do. The touchscreen and the frame buttons are all down.
Does anyone have any ideas?
Also, this gtab has not been modded in any way.

You may have to remove the bottom and press the soft reset button.

How do you take the bottom off? Will that void the warranty?
Talked to Viewsonic and they said if the screen is not working then there is basically nothing they can do. Returning it is really the only option, be it to the store or them.
Asked about a reset and they said I could take the back off and the battery, but that it would void the warranty.
Any more ideas?

99 % sure this will fix your problem
Here is a link to a post that I think will solve your problem.
Viewsonic told me there was no fix for the screen problem but this process fixed
the same problem on my G Tablet. Viewsonic told me to send in for repair.
This fixed my screen and I did not have to open the tablet.
Let me know if you have questions about this.
When you boot this up to do the calibration, place the G Tablet flat on a table and once you turn it on, don't touch the Tablet or the Screen until after it boots.
Go back and remove the file once you have completed calibration.
You may need to have or go buy a micro SD card if you do this from sd2. Mine cost about $12.00 at Office Max.
Read this thread: http://forum.xda-developers.com/showthread.php?t=882577

Try This
This is a cut and paste from page 7 of the link I gave you in my message above.
Here is another way to do this.
1. put microsd card in Gtab
2. open ES File Manager
3. open your sdcard2 folder
4. hit menu button on tablet
5. select add new from menu option
6. select new file
7. type in "calibration.ini" with out quotes in file name.
8. reboot and enjoy new touchscreen sensitivity.
Or if your screen won't respond at all (like mine was), put your Micro SD card in its carrier and put it in an SD card reader port on your PC.
Use notepad to create an empty file called calibration.ini (make sure Windows does not add the .txt extension to your file) and save it to the root directory of the SD card.
Power down and pop the SD card into SD card2 slot on the G Tablet (behind the door on the side).
Power up the G Tablet and don't touch the Tablet or Screen again until after it boots. Power back down and pop the SD card out and remove the file or rename it.
Your screen (and almost everyone else with the same problem) should now work.
If the G Tablet finds an empty calibration.ini file in the root directory of the SD2 card, it automatically runs its calibration. Once you run the calibration you need to delete the file or rename it so it does not run again.
You do not want it to recalibrate everytime you turn on the G Tablet because as you handle the screen during boot up it could mess up your screen calibration. That is why you must not touch the screen while doing this calibration.
Good Luck, I hope this solves your problem. Also, thanks to everyone who helped me when mine did this same thing.

Did you ever get the touch screen working?
Just curious, did you ever get your touch screen working?

[Q] Black screen with led lights lit

hello guys. usually when phone's plugged in to my computer for file transfer or after that, i cant use the phone. when i press the power button, the screen stays black and i cant touch anything, while the 4 touch buttons are lit up. its very annoying as i have to do the battery-yank thing and turn the phone on again. any solutions?
Yeah. Same think happened to me when my SD Card had bad sectors. Just buy a cardreader and scan and attempt to repair'em. If that doesn't help, just make a back up on your PC, format your SD Card and backed it up.
Hope it works for you too...
P.S. When I was using with my phone during file transfer and my phone freezes, it doesn't go black but stays with the current "frame" and just the LED lights. I don't know what's in your case.
Check this thread out. It is pretty much the same thing.

Also you can use Androidini Open Recovery to check your sectors on the SD card. Works for me.

[Help] Money reward guaranted. No fisical buttoms

Guys, I have a problem that is driving me mad. I have a Huawei u8100. I recently installed a custom rom that might not be adecuate for my mobile. (http://forum.xda-developers.com/showthread.php?t=1295844)
First, the ubication of the backward arrow doesn't fit with the "touchable zone". I have to press it a few cm left to make that butom work. Well, I try to recalibrate a few times and now I have a phone with no one of the buttoms working
The buttoms are not phisical at all, I mean, they are touchable but they are at the end of the screen. Well, the problem is that if I touch the buttoms, the phone thinks i want to touch the end of the screen (for example my launcher dock).
I wipe all things , and installed many rooms and try with thousand of backups, but nothing worked. And obviously i can't fix this with the calibration app.
I'm desperate, I need something to help me. I promise I will give you all the money that I have in my paypal account (Around 2 dollars, it's not much, i'm not gonna lie). Please, help me. Sorry for my english.

Happened to me twice before, it is a pain in the rear. To fix you need to change your lcd density. Many apps from the market can do this. Find out what your screen density is supposed to be. Now here is the tricky part. When it happened to me none of my buttons would work on the touchscreen because they where all out of frame. I managed to remember how to scroll down to change the screen density and I use my trackpad to scroll down and change the screen density. Now what you can do is download a rom that has the screen density setting for your device, do a hard reset and flash that rom. Or, if memory serves me correctly, you can use the update file for your firmware version. Create a folder called dload on your sd card, through using 91pcsuite and connecting phone to pc via usb, go into recovery mode and mount sd card to inable the cre3ation of this file on the root of your sd card. Next you must find the UPDATA.APP file with your phones original firmware. Place that inside the dload folder you just created on your phones sd card. Now, switch your device off. Now press end call button, volume up and power on key. Keep holding all these down until your screen says, Installing firmware update. Once that is done the phone will switch off. Switch your device back on and give it time to load. Everything should now be just as if you had recently bought your phone. Anyways, hope you come right dont worry about the money, Merry Christmas, and let me know if you still struggling. If this doesn't work then you better hope someone is going to buy you a new phone for Christmas. It took me 5 hours to get mine going again. Never play with screen density settings and whach what roms you flash as some have some hidden B.S. Good luck and God Bless.

if you want to change your density you need to change ro.sf.lcd_density=
in the build.prop in your system files. (to maybe 160 or something)
Men, you are a genious. I managed to install the app, but i'm too scaried about changing this because i don't know what numbers i have to put. Can you please tell me that?

Man i tried to reduce the lcd densivity and the screen looked smaller, but i wasn't succed in reached a good calibration, the screen automatly goes hiper messed up and i spent a lot of time to reach the calibration acceptable like it was but with no buttoms ( and using zmooth lite app). I'm too terrified to touch something again, so i will wait for you to help me .
And the i didn't understand too much about the second method. Tawahaha told me to do something like that

Hey bro, if you have downloaded a custom rom.zip, open that zip file in windows with unzip etc. You will see a file called Build.prop, open that file in your windows with notepad etc, Now only go and change the part that says some thing like ro.ril.desity=250, This is just an example I am giving you so do not use these exact numbers. Once you find out the density for your phone screen then you can add your density into that line(i.e.=250). Once you have changed that, save the file and put it back into your rom.zip. Windows will ask you if you want to replace the existing file in build.prop, and you must say yes. Once that is waxed, wipe your phone clean, sd-card,battery stats, rotate settings, everything. Then plug ya phone up to pc via usb, open 91pcsuite and transfer your edited rom.zip file onto your sd card. Flash that to ya phone and reboot, bang, after waiting to reboot you should have the correct screen lcd density size etc. Follow these steps to the letter and make sure you have a rom.zip that relates to your phone. Otherwise, download original firmware for your device, put it on your sd card in a folder called dload. Then pull out battery and turn on by holding endcall(red button), volume up and power on. Hold these keys down in order and keep each one pressed while pressing the other. You will see your phone saying"installing and unpacking firmware update", once this is done reboot ya phone. Either of these methods will work for you and dont be scared to try these things out. Your phone is basically useless now so anything you do can only improve the situation, so go wild and have a ball. This is the only way we learn, do not stress, sooner or later you will wax it. Especially if you follow directions well and can do google searches well. Anyways bro God Bless, hope you wax it.

What has most likely happened is you used an app like advanced settings/ toolbox pro, and you changed your lcd settings, which is what I did twice. It then tells you to reboot and then your screen is screwed. Now, what you have to remember is somewhere on your phone, these stupid settings have been stuck/glued in place, because it seems that you are unable to rectify by wiping. Make sure you install the correct recovery, try huwei ideos 3.0.0.5, this works well. Then try wiping again before installing/flashing a new rom. If you can wipe everything correctly then these settings will dissappear and installing a new rom will fix the lcd density prob. Wipe, wipe,wipe.

Oh,and make sure you get the exact density for your screen, not smaller, not bigger, exact. Otherwise you sill not have the correct aspect ratio no matter what you do. Exact, exact, exact.

Mmmm. I opened all the roms that i' ve found for my phone and all says density=120 (included the wrong rom). And that's my actually rom density (and that's the correct density for my ´phone i guess, because it's the only one that gets the screen looks good and not strange)
And, I have never play with any other app apart from the calibration app (a very ****ing idiot app, because it only ask for two "press" and then it calibrates, diferrently from the calb ap from the stock room that ask for 4 points { and i hve problem with the ones in the bottom of the screen, near the real buttoms]
I have done the dload method, (with tawahahas help) like i said before and nothing happened.
I will try now to erase everything with clockwork (i can't install 3.05 beacuse i can only find the bat file for 3.04 , and i don't know how to intalled it with a different method) like you said, but I have done this before with amonra (which has more wipes options than the clockwork) and nothing happened. I don't know :S PLeeeeeeeeeease help. Thank you so much!.

Please help me reconcile some issues with rooting

So I took the plunge and tried to root a Nook 8GB today. So far I have done the following: (1) created the CWM microsd card; (2) copied the latest CM10 and Gapps roms to another microsd card.
I used thes Ray Waldo instructions for creating the cwm card:
root-nook-tablet-with-cwm-sdcard
So, I am having a problem with getting the Nook to load the CWM microsd card. It just won't start when the microsd card is in. As soon as I pull out the microsd, it starts without any problems.
I tried formatting the CWM microsd card and copying CWM again, but it hasn't changed anything.
I have a Nook 16GB. Should I try the card out on that Nook?
A couple of issues that I noticed through the process:
(1) CWM file is supposed to contain 4 files? However, part C., step 7 says "Copy all 5 items in the “CWM” folder (from item B.3 above) to the window of the new SDCard" Is this just a typo? Or is there a missing file?
(2) In Part C, step 4, after the flags have been selected, there is supposed to be a green checkmark. I see a check mark grayed out. It never goes green. (Click on the green checkmark (in the upper section of the GParted window) to execute & allow GParted to complete the action)
(3) Its not really clear to me how I am supposed to boot the nook so that it will boot off the microsd card. I understand that I am not supposed to insert the card while the nook is on because the nook will mount and write data. I have seen a couple of different versions for booting: (1) just insert the card, press power, and let it boot; or (2) hold down the power button and the N button, let go when the N on the screen goes away, and then let it boot

Step 4 reads: Turn your NOOK Tablet on. Put in the ROOT microSD card you created in Step 3 into the NOOK Tablet. Turn the Tablet off. When it’s completely off, hold the power button and the N button at the same time. Keep holding it. This is the N button: You should see the usual NOOK boot screen with the grey N in the middle of the screen. Keep holding the power and N button. When that grey N flashes off the screen you can let go. The NOOK Tablet should be off again because you were holding the power button. Turn the NOOK Tablet on. After a moment you should see a white screen with a cardboard box on it. When it finishes you’ll see a screen that says CWM-based Recovery.
Not having gotten any feedback, I decided to go for it and tried it on my 16GB nook tablet. Worked like a charm. Not a single speedbump. Maybe there is something wrong with the 8GB nook. I tried different sd cards, etc. No luck on the 8GB device.

Encrypt Galaxy Tab 2 7", ICS 4.0.3, CF-Auto-Root?

One of the first things I did on buying my new Galaxy Tab 2 7" (GT-P3100, Wi-Fi and 3G; Spanish market "PHE" identifier, came with ICS 4.0.3, no updates available either through Kies nor OTA) was to encrypt the Device. It worked.
Then I rooted the device with CF-Auto-Root, which had the side effect of performing a factory reset, and as I understand it from a brief conversation with the author of (the excellent!) CF-Auto-Root this was an expected side-effect of the device having been encrypted at the time of applying CF-Auto-Root.
So, the Tab 2 is back to un-encrypted.
Here are the details:
Android 4.0.3
Baseband version 3.0.8-CL448962-user [email protected] #1
Build number IML74K.P3100XWALD2
But now I'm trying to encrypt again (either/both the SD Card and the Device itself) and I'm having no success at all.
On trying to encrypt the SD card, each time it always returns "SD Card Encryption Error" within a few seconds. (And indeed thereafter I always get a Notification about "SD card encryption error" any time the SD card is mounted by the device). If I go back to Settings -> Security -> Encrypt SD card and select to decrypt the card (even though it's not really encrypted), then I can access the SD Card again - no damage was done (and no encryption either).
If I try to encrypt the Device, I get the black background with the large green outline android, and ... nothing. The green android on the black background just stays there. After the normal screen timeout, the screen goes completely blank; I tap the power button, get the usual unlock screen, unlock it, see the green android again ... and, nothing. If I rotate the tablet, the android rotates. If I tap the power switch, I get the silent/ flightmode/ reboot/ turnoff menu. But nothing will get me back to the normal user interface, and it never finishes encrypting (I really think it never starts).
Eventually (after more than a couple of hours) I give up, tap the power switch and select to reboot, and it comes back up fine, but not encrypted.
One of my main reasons for getting the newer device was to have encryption :-/
Is Encryption (Device, and SD Card) supported/ functional when CF-Auto-Root is in use on a Samsung Galaxy Tab 2 (Android 4.0.3)?
How do I get encryption to work, for both the Device and the SD Card?
Is there a way to get more detailed logging (the Tab is rooted, and I have command line access) and/or to command the encryption from the command line, to see what's really happening?
Thanks!
Hm, I tried encrypting only NEW files on the SD Card now, and that seems to work.
I stored a new file on the SD Card, unmounted the card from the Tab, put the card in a card reader on a desktop computer, and indeed the contents of that file are just "data", not readable. Back in the Tab, the contents are the picture which I'd saved to the card.
But still attempting to encrypt the existing files on the SD Card fails. And still attempting to encrypt the device does nothing (green android appears, but no % complete ever displays, etc, just as I posted before).
One step further with the external SD Card; I copied off all of the data, formatted the card, and then was able to fully encrypt it (and copy back my data).
But the Device itself, I still can't encrypt at all - just the same as before.
No ideas? None? Nobody? Please....?
Thanks,
-Jay
Bump?
sigh
Try the same thing with the device itself.
Do a factory reset.
Not once,twice.
I know u lose all data.
But try it.
And do this without android to start.
Keep press power+vol up.
Get into menu and do factory reset,wipe dalwik...all.
Hope this help.

This was over a year ago, and I don't even use the device anymore. Sorry, can't help.
I've since then tried a ZTE "Skate Pro" (the Movistar Spain branding of the "Blade III"). Piece of Sh*t phone. Support encryption natively under Android 4.0.4, but if you do encrypt the phone, the performance of the touch screen becomes unreliable, frequently so bad that swiping (including Swyping) actions don't work right, and you end up less moving things on the screen and more, effectively, tapping things you absolutely did not intended to tap. I discarded the ZTE Skate Pro/ Blade III.
Then I tried a Haier W708, dirt cheap; not a powerhouse, but satisfatory.
And a Nexus 5 which kicks *ss all over the place.
I can't help any more with this thread, and any results in this thread would not longer help me, so I'm dropping off the thread now.
Best of luck to all.

Phone restored to factory settings by itself while charging!? Can I retrieve my data?

Hello everyone!
Yesterday I powered off my Moto G3 and plugged it in to charge. After a few minutes I heard a short vibration, which normally means that the phone powered on by itself and is booting. I then checked the screen; I had to put in the PIN for my SIM card, but afterwards there was no pattern I had to draw in order to unlock the phone (I had one set up before!). After unlocking the screen I can see a blue screen with "Welcome" at the top, a choice of language and a yellow arrow ("next") button in the middle and "Emergency" call button at the bottom. And in the top right hand corner are the usual signal strength and battery icons.
When I press the yellow button, I'm asked to connect to a Wi-Fi network. I haven't proceeded beyond that point, as I don't want to mess up my phone even further. Basically it looks like my Moto G3 returned to factory settings and wants me to set it up for first use.
I then tried to reboot the phone a few times. I always get the standard Motorola "stitching" animation and get booted into the described screen. I also went into recovery mode, but almost every single option booted me into the blue screen and one time I got the "No command" screen. But maybe I did something wrong; I'm certainly no expert when it comes to using the bootloader.
Having described all of that, my questions are: is it possible for the phone to have reverted itself to factory settings? If yes - why and how? I have an SD card with a lot of photos, documents and application data that is very important to me. Is it still possible to retrieve the data that was saved on the device?
I would very much appreciate any help with this problem!
Thank you,
Meletel
You can copy the contents of the SDCARD while in TWRP.
1. Put MicroSD card and copy the contents of Internal Storage to microsd though TWRP File manager
2. Connect your phone to your computer by USB Cable while in TWRP and you can access your phone through MTP
