[Q] My tablet bricked need help - G Tablet Q&A, Help & Troubleshooting

USB port not working, so I cannot connect to the computer to do nvflash or adb.
Getting android.process.acore has stopped message after start. I have the stock update.zip in the internal sd card because of which every time i do a recovery it trys to install the stock update and throws teh FC error. Not able to get past the FC error. Tried putting the clock work recovery in the external sd card but because of existing update.zip in the internal sdcard, external is not read.
I am not able to get past this. Any help is appreciated.

What makes you think your USB ports are not work...maybe you haven't downloaded the correct stuff and configured it correctly (adb & apx drivers).
Go here http://viewsonic-gtablet-for-dummies.webs.com/ and follow code red. Follow the instructions step by step & download everything from the links on the site. If you still have a problem, post a message on that sites forum.

Don't take this wrong...just asking questions to try & help out. You would only see an unknown device if you had not installed the drivers (apx and/or adb). Once you have installed the adb & apx drivers for one gtab it will not be unknown. Are you sure you are entering apex mode correctly...hold power+volume - ? Screen will display 3 birds then go black!

Yes. I went to the apx mode correctly. Still did not see my device recognized.
I am looking for a solution for bypassing the FC temporarily or to clean the internal sdcard. once the internal sdcard is cleaned, i can use the external sdcard to do the clock works mod and go further

Take a look at this thread & see if it helps http://forum.xda-developers.com/showthread.php?t=853537&highlight=android.process.acore

I am not able to get past the android.process.acore error. I think i will be able to fix it only if the usb drive works, i am going to call viewsonic and see if they will take it in for warranty repair.

[Q] Help - USB question under Cyanogen 7

I am a complete noob when it comes to Android, having first got my G-Tab yesterday. I'll give some background before I get to my question.
Yesterday, I sideloaded a couple of apps by essentially copyng them over to the root directory on the G Tab. But, like most others, I found the stock OS very slow and unresponsive. So I installed CyanogenMod 7 as per some simplified directions that I found. Everything went fine. That's not the problem.
My problem is that I cannot sideload anymore. When I plug in my G-Tab through the USB, I hear the Windows two thumps, and nothing happens. I look to see if my tablet is showing up in the Winders Explorer, and it just shows a bunch of memory sticks that when I click on them, I can't access. Also, nothing is showing up on the tablet either (no dialog boxes like under the stock OS, nothing). This is a big problem for me since I don't have access to WIFI at the moment.
Does anyone know how I can make my computer and tablet see each other? If you tell me to do something, please tell me where to find it. For example, on another thread, someone advised someone else to turn on USB debugging for something, but I can't find any option for USB debugging in Cyanogenmod 7 under settings. Thanks in advance for any help you can provide.
Additional info:
Computer: Laptop running Windows Vista
Did you try swiping on the notification area and enabling USB transfer on the tablet?
If you don't do this, your computer will see the USB device but not as mass storage.

Here is where this is....
Menu >>Settings >> Applications >> Development. 1st choice, USB Debugging.
Thanks. I did swipe in the notification area, and the only notification there was that USB debugging was activated. But still the G Tablet and computer cannot see each other.
Double check in your device manager (PC) to make sure there are no issues with the drivers.
Thanks. I found it and also found out that it is turned on by default. So I guess that doesn't help.

Does Cyanogenmod 7 require special drivers? The drivers worked fine on the stock build, and nothing changed since then. Everything looks ok.
I plugged my Gtablet (CM7.02 with Pershoots 4/30/11 kernel) in to my computer just now to test. I haven't used it on this computer since installing CM7. I did just work on my boss's Gtablet the other day running both stock TapnTap and VEGAn 5.1.1 and it worked fine on his.
I plugged in the tablet, Windows 7 (32bit) said it was installing drivers, driver install completed successfully.
On my tablet I then swiped up the notification bar and tapped on the selection that said "tap here to mount USB to share files with your computer" (or something like that). The Android mascot screen popped up and I tapped "Turn on USB".
New drive opened up on my computer that was the gtablets /sdcard.
So it works and used the same driver as before.
No special drivers for CM7.
One nice thing about CM7 (or maybe Ginger) is that now when plugging in you get access to both the internal and external SD cards from PC.

My computer Vista (32 bit) at no point said it was installing drivers after I upgraded to Cyanogenmod 7.
When I swipe the notification area (and I assume that the notification area is the area at the top of the tablet's screen), I get a menu that tells me that USB debugging is activated and that's all. No option to mount USB. And no screens popped up to ask to turn on USB. None of this.
And when I plug in the USB, as I mentioned, I get the two tones from Windows, and 3 new removable disk drives appear. But when I click on each, I get am asked to insert a new disk.
That's all the info I have at the moment.
At this point, I'm so sick of it. I think that probably somewhere a switch is not flipped or a box is not checked, but I have no idea where that could be. I'm seriously considering using ClockWork mod to restore the system. But I'm loathed to do this since I spent 2 hrs. downloading Cyanogen Mod last night (I have a slow internet connection).
I would suggest that you turn off "USB debugging". That setting exists to activate adbd on the tablet, and normal users, usually, never need it. Enable "USB debugging" only if you need to use adb.
After disabling USB debugging, reboot the tablet, and then connect the USB cable to the mini-USB slot on the gTablet. As soon as you do that, on CM7, a USB Mass Storage screen with a green Android will pop-up with a message saying "USB connected" and button to "Turn on USB Storage".
Click the button and a warning that "If you turn on USB storage, some application you are using will stop and may be unavailable until you turn off USB storage.", will appear. Select OK. The green Android will now turn orange and the screen will say "USB storage in use".
Use the "Turn off USB storage" when you're ready to wrap up.
Ok. I think I might have solved the problem, but some intervening events makes me not sure. Basically, I restored to factory and then put in a different ROM, VEGan7. However, while doing this, I think I might have found the solution to my original problem.
It turns out that it does seem to be a problem with Windows, or at least with Vista. I had the same problem with VEGan7. But this time, I right-clicked on the "removeable disk" that appeared under "Computer" (where you see all your drives) when I hooked up the G TAB via USB. After I right-clicked, I selected properties and then clicked on the "Hardware" tab. You will see a list of all possible storage devices to associate with that icon. I chose the one containing the string "Tegra2" and I was off to the races. I was then able to perform the actions mentioned above about activating the USB on the G Tab.
I suspect I could have used this technique with Cyanogen 7. The only thing that I question is that I saw 3 removeable disk drives appear and not just one. I hope this helps someone else who might run into the same problem.

Did you by any chance have an external micro SD card on the tablet?
If so, I'm thinking that you saw the 2 SD cards + the APX debug mode device.
flash this zip (in post #3) to mount the internal storage as an SDcard instead of EMMC. If you run that then you should be able to mount the storage when running CM7
http://forum.cyanogenmod.com/topic/20913-cyanogen-7-viewsonic-g-tab-usb-connection/
also your other option is to boot into Clockwork recovery then go to mounts/storage and mount usb
you should then be able to transfer files back and forth

No, just got the tablet. Didn't have time to fool with external Micro SDs.

Thanks, I'll give it a try. What are the ramifications of mounting the internal storage as an SD card instead of EMMC? Do I lose performance? I mean, there must be a reason that the default is EMMC.
I wouldn't want to boot into Clockwork every time I want to transfer something, apps or even music and videos. That would be a real pain. Actually, I was surprised at how long this tablet takes to boot up after a complete shut down.

From what I have read that's the way that Gingerbread does it. Some programs actually have problems with that configuration, that's why people do this.

Do you think you might post the file here. When I go to that link I'm not allowed to download it. The irony is that that link says it came from here but I've used the search and I can't find it here. Maybe it is just day after Cinco de Mayo problems I'm having?

[Q] Help - GS2 connection to PC

All,
I've tried everything and I cannot get my PC's to recognise my GS2.
It's not even constant, sometimes I connect it via USB to the PC and it comes up as unrecongised device, other times it will detect as a camera as GT-i9100 (regardless of it I select MTP)... I've reinstalled Kiers I don't know how many times and have even manually installed the drivers but still no luck.
So I gave up with that as I only want to connect to Odin to get rid of this crap software. So I downloaded the CWM root package onto my SD Card and booted into recovery, went to apply the zip and it says it cannot mount /sdcard as not such directory exists?!?! Now I don't have an external SD Card but the .zip file is located on the internal storage in /sdcard/Downloads.
I have a Mac at home that allowed a connection into Kiers first time to update to stock ICS - should I just abandon this trying to connect to Windows and try and find an alternative to Odin for Mac?
Thanks for any help at all.
Dan.
but the .zip file is located on the internal storage in /sdcard/Downloads.
NO try copy pasting update zip file on root of SD card then try....
Edit : this rooting methed you can only try on ICS vesrions
Thanks ZACQ8.
I just thought I'd try another USB cable as a last shot, and OMG it started installing the drivers Still failed to install the Mobile MTP Device but it's getting there...
You have to use the same USB port when you connect your SGSII.
I noticed that if I plugged it into another port the phone would come up as unrecognised - this was all tested on a few PCs when the phone was on GB and connecting as an external hard drive.
I haven't tested if the problem still exists with ICS, as it do 'external hard drive'.
Seems like it was the cable all along...
Phone now recognised in Odin and Device Manager.
Pile of crap.

Problem when plugging my S3 with USB to PC

When plugging my S3 with USB it only says its a portable mediaplayer and does not show whats on my SD-card, Please help!
the fact that it shows as a portable media player is normal: that's what it shows for me when it's either rooted or stock. you should be able to click on it and see 2 storage options your internal storage and the SD card.

do you have an SD card installed? maybe it's the drivers not working. try on another PC and see if it'll read.
Drivers Problem
This frequently happens to my computer so I know how you feel.
To solve this problem,
1. Go to devices and printers.
2. Click on your S3 device, it should be there.
3. Look at the bottom of the window
4. If it says that the device needs troubleshooting, right click the device and select troubleshoot.
5. Wait for troubleshooting to complete
6. Your SD Card and Phone memory should now pop up on your computer.
Unfortunately i have not been able to find a permanent workaround for this problem. So this solution has to be applied everytime you connect your phone to the pc.
Hit thanks if i helped you!
thanks guys! i got it working!
Did you use my solution to get it working?
I found when I use stock firmware that changing from connect to MTP to PTP and back again, my computer finds the phone, eventually but running an AOSP or Cyanogen the computer finds it without any problem

NT/USB CONNECT: MTP then USB COMPOSITE then NT but no joy!!

I've had this problem for a while (not being able to connect my NT to my computer) and can't seem to resolve it. I happened to have to upgrade my hard drive and hoped the clean install of XP would fix it but it didn't!
When I connect my NT to the computer via USB (running Paranoid Android 3.01 off 32GB class 4 Sandisk SD card, and yes, I have USB Debugging enabled) I get the following:
The NT is recognized as the following devices, in this order:
MTP
Composite USB
Nook Tablet
The hardware installer opens after each "device" is recognized. Finally I get to Nook Tablet after cancelling the two previous hardware install requests but a third pops up and then I get a message that there was a problem with the installation!
I had been able to fix this problem previously by running usbdview and uninstalling each device, then deleting the device drive letter assignment, and finally running my Norton 360 Registry Cleanup Utility. But, now, that just isn't working!
I surmised that I was having a problem with the drivers. So, I surfed the web and found the USB Driver Zip file from Indirect's OP on rooting and installed them on my computer again. No luck.
I managed to get into a log file (don't ask me what it was called, I forgot) that was in the WINDOWS/DRIVERS/i386 folder. It mentioned a paging error occurred during the process of attempting to connect the NT to the computer. Does this mean my SD card is bad? I have had no problems using it to run the PA ROM on my NT, at all. From what I read however, that I could try to understand, a paging error has something to do with a problem with the SD card? Certainly I can just reinstall the ROM, in another card if necessary, or load a new one. However, I'd like to be able to get my content off the card without having to drop box all the files to myself (a decent but slow workaround).
I know I could try to use ADB over my wireless connection somehow to achieve this as well, but that is over my head right now.
Any suggestions regarding what is going on here would be greatly appreciated!
Thanks

It's not clear from your post if you're merely try to connect the NT to your PC via USB for media content transfer, or for ADB access.
If the latter, http://forum.xda-developers.com/showpost.php?p=35971559&postcount=13 might be of help.
Oops, sorry. Just for content access/transfer.
Actually tonight my device seemed to reboot while I was in the middle of composing a document (data viz word). It's never done THAT before. Interestingly, it seemed to skip cyanoboot and go right to the SD ROM. The WiFi needed to be manually connected thereafter (usually auto connects). The reason I think it rebooted and it wasn't the screen flaking out as a problem is it went black and then right to the first animation for PA 3.01. But this seems to make no sense!
Maybe the SD card IS failing?
Yes, I am trying to avoid having to learn ADB access. Too tired (you know why Digi.) If I must, I will shell out for a new card and maybe try one of your newer ROMS......it's probably time for that anyway. But the card is only 6 months old
I will test out trying to access the NT on the computer via USB without the SD card mounted. Maybe that will shed some light.
Thanks as always.

Noob mistake. Wiped data in TWRP - Including the OS

My G3 is a blank slate right now.
I put the SD card into my PC and downloaded the CM12 file and the Gapps file. Now with it back in the phone I can't find them. I click install > External Sd > nothing there.
Under "mount" it wont let me click the SD card.
Where do I start?
I would plug the phone in and reflash back stock and start over. But u could try mounting the the phone as usb storage and dl the files directly to it thn search for them on the internal storage since it wont connect to the sd.

Plug it into where and reflash it how? You have to ELI5. I'm reformatting my SD card now to see if it will recognize it.
Wow. I really had to go through some trial and error there. I spend the last few hours trying to get the ADB side loading to work. Trying ever driver known to man. I kept getting the no devices message. There was a specific order that it had to be done in order for it to be recognizing the device at the time of loading. Enable mtp > adp > plug in > side load.
I'm up and running CM12 now. And I'm ready for bed!
Since you have twrp installed, why not just get an SD card and put a ROM on it and flash? Seems like the easy way to me.
For future reference, was the phone recognized by adb when in TWRP? If so, did you try to push any files to the internal storage?
I did that once I just flashed a tot file then just rerooted I couldn't connect phone back with adb or anything
