[Q] Thanks! (and HELP!)

Just joined to say thanks to Roebeet and everyone who is active in this forum. Because of the obvious potential of the gtablet being explored here, and discussed on phandroid.com I decided to take the plunge and purchased one tonight. I might have passed this tab by, and waited months for something else...
--and here's where I cry for help!
I carefully followed a series of step-by-step instructions I found thru google, to install the latest tnt lite found here on XDA. Everything seemed to work without a hitch, and was prouder than a pappa to have completed my first root and mod ,ever!
BUT right after I DL'ed and installed the flash 10.1 apk things went south. The browser constantly crashed to the home screen, and the market and email apps were crashing also. I rebooted and now I am greeted by the tnt setup screen that is covered in an endless wave of crash warning dialogs! I can't tap them away fast enough to see the desktop.
I've tried to do a recover, but I can't get thru the setup (that keeps crashing to the first screen also) to use the USB to mount the internal mem to my Mac.
I am insanely happy about the potential of this hardware, but I've painted myself into a corner. ANY help would be greatly appreciated.
And yes, I do look very handsome in my profile pic.

From bad to WORSE!
I discovered the dcom222 thread that describes my problem and details a solution. I followed it to the letter, changing the command and using my microSD as a secondary boot to reinstall the vanilla tnt ROM.
But then it just stuck on the tnt logo, faded in and out 3-4 times, and went dark! The device won't turn on or off (had a full charge when I pulled it from the wall socket a few moments ago)
Please tell me I haven't bricked this thing!

still no luck...
I was able to power the unit back up, but I've tried to recover and flash all three setup files I have (vanilla tnt, ota update tnt and tnt lite 2) but nothing works!
All of them create a loop of some sort, whether it's the viewsonic screen, gtablet screen loop, or the tnt logo screen blinking on and off, NOTHING boots to the desktop.
Going to bed before I drive my self insane. Hopefully someone in the know will reply by the time I check this at work.
thanks in advance

You have not bricked it, don't worry. This device is very hard to truly brick. If all else fails there is nvflash or the apx mode fallback. But I don't think you need that if you are still able to boot to clockwork recovery.
In clockwork go to advanced - mounts and try mounting and unmounting your partitions. I suspect your user partition may be screwed. This seems to happen fairly frequently especially the first time you flash a ROM. It happenend on my first flash and not again since. Clockwork lets you repartition though. Search the forum for partition fix, its not too big a deal.
If that fails try roebeet's thread on nvflash recovery for TNT lite. If that fails, search for APX mode.
As far as I know there are zero bricks from ROM flashing so far.

feeling better
Thanks for the assurances that I didn't wreck the device, and pointing me to some solutions. I have a few questions:
what is clockwork mod? If I am able to recovery boot from my micro SD card, do I already have it? (I downloaded a bunch of recovery images to start, per instructions)
If it's something I still need to download, is it a PC application? How am I supposed to change settings in it (manage partitions, etc) if I can't get the tablet to boot?
-- stuck at work and dying to get home to fix this thing...

Ok, more detailed instructions:
If you press and hold down Volume + when you are pressing the Power button to boot up, and keep holding the Volume + key until you see a message that says "Detect a Recovery Key Pressed", that should get you to a text menu from which you can navigate using the volume +/- keys and the Home soft button to flash ZIP files and do other things. That menu is ClockworkMod Recovery. Since you remember installing a recovery.img, it sounds like you probably (hopefully) have ClockworkMod Recovery on there.
If you get to ClockwordMod Recovery, you can go down to the Mounts and Storage option, then you will find the "Mount USB storage" option at the end of that list. That lets you plug in and mount your internal memory area as a standard USB drive to your Windows or Mac computer to copy over new ZIP files and the like to your G Tablet.
You can also check that partitions are all mounting and unmounting successfully in that menu. If you go instead into the Advanced menu, you will see Partition SD Card, which I believe is what you might need to do at this point.
If booting with the Volume + button held down doesn't get you anywhere and you see nothing about Recovery Key Detected and don't see any text menu, then you don't seem to have a working recovery. At that point you'll have to do what phfaty suggested, read the post he referenced, and follow the link therein to the tegratab forum post to get the NVidia Tegra SDK installed on your Windows desktop and use the NVFlash tool and APK mode (where you hold the Volume - key down while booting instead of the Volume + key) to reflash your tablet.

still not working...
The good news:
I do have clockwork mod installed. Must have been in 1 of those zips or rars I ran in the very beginning.
The bad news:
it's still caught in a boot loop. I've mounted it as an external drive 3 times now from clockwork, and tried all 3 versions of the operating system (vanilla, vanilla with the ota and tntlite 2) and NOTHING makes a difference.

1)Boot into clockwork.
2)Navigate to Advanced menu
3)Choose partition sdcard
4)Choose data partition desired size(1024=1GB)
5)Choose 0GB for the next selection(swap not used)
6)Do a factory reset from main menu
7)Reboot
8)If that doesn't work, then reinstall ROM, then reboot

UPDATE
partitioning the drive and wiping the user data did the trick. I'm up and running again. thanks to all who chimed in to help.

[Q] Touchscreen not touching

Hey was looking for a little help or guidance.
The touchscreen on my HTC Sensation 4g stopped working. Everything else works, volume rockers, power button. Even on the home screen it shows the volume increase/decrease but none of the apps are touchable and the lockscreen won't unlock either.
I used to be on Cyanogen Alpha8 when this happened before. I flashed to alpha9 and it fixed the issue. This time nothing is helping. I wiped the phone a couple times now, including wiping the sd card even and have deleted/installed Cyanogen 7.1 alpha10 and Android Revolution HD a couple of time seeing if that could fix the issue. Apparently it's not the rom as neither worked.
Recovery and everything works fine, but even when I did a backup restore it didn't fix the issue. Is this hardware?
TLDR- Touchscreen and lower 4 android buttons do not respond. Physical buttons all still respond.
Is there some screen lock key that I enabled and don't even know about or something?
First it happened when phone was 10 days old, now it happened again 10 days later.
Thank you for any help.

If you remove your cover, you can se a "polished" square on the right side. Make sure that it has good contact with the small metal "plate" on the right side of your phone. It's the touch ground, and I've seen people resolve their issues by checking that.
There is a thread about this, I can't find it now though. Using my mobile. Search for "sensation touchscreen issues" or something like that.
Sent from my Sensation using xda premium

Yeah I've tried extracting it a bit to get better contact. It's not that the touchscreen stutters in working, it doesn't work at all. When I'm on the lockscreen and pull the ring on Android HD rom it doesn't budge even the slightest. No notion that it is recognizing any kind of touch input. Thanks for the suggestion, I'll post back if it fixes the issue somehow later but currently contacting that small little square better hasn't helped.
I've read up on a few touchscreen issues like that but couldn't find anything so thought to post on here. Thanks again for the tip but touchscreen still not working.

Try doing the procedure from my sig. I'd suggest to discharge first, leave overnight with no battery, and charge with no touching... It's all in that thread.
But... I still haven’t heard of a case when the screen didn't work AT ALL. Perhaps your issue is a bit more drastic and can’t be fixed so easily :\

Tried it. Didn't work. Put in foil as well, that also didn't work.
Thank you for the suggestion though.
Touchscreen still does not function AT ALL, with or without the back cover on so it's not the usual grounding pin issue I think. Could a cable pop out somewhere inside the phone to disconnect touch feedback without disabling the actual screen? Anyone have any hypotheses?
I would like to exhaust all methods before cracking open the phone and voiding the little warranty seal just in case.
Very annoyed at this phone/htc. Thank you for all the help on here guys and gals.

If you already tried clearing all the cashes, flashing several roms and different kernels, than it's hardware. Take it to a service center... :/

same problem
hey, any luck on solving your problem? i have precisely the same problem with my htc sensation as well. was working perfectly but now it wouldnt respond to any thing at all. it wouldnt even let me use ruu to restore it back to the original firmware. i really dont want to crack it open. i have ordered a new battery touse to test it. will kep you posted. did you manage to solve yours?

fix for none working screen
Hi there " dude that started this thread V*****"
i have managed to fix my screen issue. it involves having to take the phone apart VERY CAREFULLY. The flex behind the screen sometimes comes loose. all you need do is just fit it back in. You have to be careful though as there is a possibility you might damage the phone. oh, doing this will VOID your warranty. look on youtube for how to take the phone apart. i just bought another one on eBay and am going to fix it. best of luck and let me know how you get on.

So I have this issue as well. Can you tell me what exactly you did to fix it? What flex came loose? And what did you buy on Ebay to fix?
Thanks

I did this last night and managed to fix the touch screen. The flex is located on the underside of the top PCB, the one that has the little chip on the cable. Mine looked ok but I pushed it in gently and did a quick test just by booting the phone before putting it all back together.
If your screen looks fine but doesn't respond to touch at all then I suspect this is also your problem. Worked for me :thumbup:

I know this thread has been inactive for a while but just thought I'd mention I just had this problem of dead touchscreen and fixed it simple by squeezing my phone! I took the battery out and pressed all over in the hope of pushing in any loose cable and it is perfectly back to normal just thought I'd mention this to save any potential future sufferers from taking their phone to pieces!

I have had this issue twice! I have a Motorola droid 4, and the touchscreen simply goes dead. First time it happened, I had just hung up with Verizon Customer Service. I fixed it by changing the slider/touchscreen assembly off of a different D4. Now it's happened to that assembly too. I"m starting to think it's a software issue. I will try this fix however. Dry heat was suggested as a fix on a different forum. Hope this helps someone.

The only working solution i find that works perfectly for touchscreen problems
I have tried every single solution for touchscreen issues on this site. I have found one that is basically guaranteed to work here it is:
INSTRUCTIONS: (YOUR PHONE WILL NEED TO BE ALREADY S-OFF AND UNLOCKED FOR THIS TO WORK WHICH YOU CAN DO THEN RETURN TO THIS TUTORIAL)
YOU WILL NEED TO DOWNLOAD THEESE 2 FILES
Recalibration tool - http://www.mediafire.com/?akul70qy128lo3u
Revolutionary hboot - http://www.mediafire.com/?1ed2y87pld66638
1. Take the NBH file from the provided link, and place it on root of your SD Card.
2. Boot into bootloader, by turning off your phone and then while its off hold the volume down button and then hold down the power button until the bootloader comes on then release bot of the buttons.
3. Once you’ve booted into the bootloader wait a second and you will notice that it searches for and finds the nbh file that you put on your sd card, It will then proceed to flash it. Some instructions will appear on the screen very quickly for about 2 seconds asking you to hold the phone horizontally while it calibrates it. Do this quickly and follow the rest of the instructions.
4. You will now see a screen appear giving you 2 options. Run the first option by selecting using the volume button if its not already selected and press power to run the process then run the second one once it is complete. Then simply remove the battery from your phone to turn it off.
5. Once again using the button combination, boot into the bootloader and select recovery. Once recovery boots into clockwork mod, do a factory reset and wipe data as well as the dalvik cache. Then reboot your phone.
Your touchscreen should now be calibrated and working perfectly.
Do not forget to delete the nbh file from your sd card once you’re done so it does not auto flash next time you go into your bootloader.
IMPORTANT!!!!!
If the process of flashing the nbh file does not work and gives you an error like this
“Security fail! Update fail! Press <POWER> to reboot.”
This is because the firmware is not the right one needed to flash the file and this can be corrected by flashing the Revolutionary hboot v 1.27.0000 following these instructions:
1. First make sure that you deleted the nbh file from the sd card root.
2. Place the file named “PG58IMG.zip” at the root of your sd card.
3. Power off your phone and use the button combination to boot into the bootloader.
4. The file will be detected and automatically start to flash, follow any onscreen instructions if necessary until this process completes.
5. Once this completes your phone should boot so that you can delete the zip file from your sd. If the phone is taking too long to boot you will need to remove the battery then the sd card. VERY IMPORTANT “With the sd card out of the phone” you will need to boot into the bootloader once more and enter recovery and factory reset the phone as well as wipe the data and dalvic cache.
6. Now the phone should be powered down and the turned back on. After the phone is finished booting up you should then replace the sd card and use whatever file explorer you have to delete the zip file from the root of the folder so that it does not autoboot the next time you enter the bootloader.(or you can do this whole step by deleting the zip file using a card reader and your computer)
7. You have now successfully flashed the correct firmware/hboot which is the revolutionary hboot required for the recalibration tool to work. Now you can try to reflash the calibration tool following the instructions at the very top of this tutorial again with the nbh file and it should work since I had to go through all this for mine to work and now my phone touchscreen work like a charm and is in perfect working order.
8. Thanks. I do not take credit for this fix, I have simply made a detailed explanation of how to get it to work as intended by this user on XDA http://forum.xda-developers.com/showthread.php?t=2437293

I tried this on my droid 4. I followed the directions for the .nbh file, and when i got into the bootloader, nothing happened. it ended up booting normally. so I tried the .zip file. same thing, I got into the bootloader, nothing happened, it timed out and booted normally. I am at a loss as to what I did wrong. any suggestions?

I should have mentioned that this method only works on the HTC bootloader as it is very different from other bootloaders.

Bricked MTCD KGL unit with Malaysk soft

Hello,
I downloaded the latest Malaysk software from the repository, tried installing it with the second method (from "System update") along with wiping flash.
Now this KGL MTCD unit is bricked, there is no response from it, aside from the buttons lighting up.
How to unbrick it?

can you get in to the Recovery?
Never change a running system if you are not knowing what you do

Yes, if you can get into recovery you can just flash. In the thread it clearly says that you have to get into recovery BEFORE flashing (because you have to flash twice due to partitioning).
Ask your vendor how you can get into recovery if the usual way (pressing power + reset at the same time, then releasing reset and pressing power a single time again) wont work.

Just get in recovery and use the Wipe data / reset cache option, then flash it again from recovery.
Reboot and enjoy

If I could get into recovery I wouldn't be posting this topic.
Recovery doesn't work.
What now?

TO get into recovery,
when it should boot up, press and hold power.
THen it will force shutdown. Next boot brings up recovery for me!

same here bro
the unit is totaly dead, cant go to recovery...

Oh well, I'll just replace the motherboard.

for all of you with bricks. lets do some experiments
Can you guys hook it up to a computer and see if the computer can read it. If you can you should be able to adb the rom back.
http://www.rockchip.nl/downloads/
Make sure you have the drivers. If you can successfully read it then you can use RKTools or adb.

But I suppose that you loaded on RK batch tool the factory Mcu and firmware right?
Because in my case I can't find factory mcu and seller doesn't know to provide me the factory software.
So with batchtool what can I do?

Factory firmware failed checksum. So, I used Malaysk ROM. The latest version failed to erase screen, but, the previous one booted successfully. Initially I tries to use recovery and ended up in brick device. Only rear camera was working. The devices stacked to Malaysk ROM screen and no stand by if ACC OFF.

Hi there,
Trying to install Malaysk ROM on an MTCD-KGL unit, I managed to get it bricked. As in... no screen, no sound, no Recovery, nothing! Couldn't link it to PC, nothing. The reset + volume button combination did not work for me to enter Recovery. My screen was all dead.
So... After some research, I used "Rockchip Upgrade Disk Tool" v1.4 and the unit booted from the sd card inserted in the GPS slot (Guide here: http://wiki.radxa.com/Rock/SD_upgrading ).
In theory, the unit should have started automatically upgrade from the SD but in my case it presented an error requesting me to remove the sd card. After removal, the unit went to Recovery boot menu. Still a success.
When the Recovery menu appeared, I inserted an sd card with dupdate.img on it in the GPS slot and selected install from menu. Unfortunately, the unit kept saying that it does not find the sd card. Tried the other sd slot but same error.
Success came from USB port. One of the two from the back of the unit, not the one in front. I put the dupdate.img and dmcu.img on an usb stick and inserted in one of the usb ports from the back. The unit recognized the stick and started the update process.
Now the unit is working.
If someone is interested, I can provide MCU and ROM (version from October 2016).
Hope this helps someone.

Hi,
Before you saved your unit, did button light light up or not? I have same issues like you had, but unfortunatelly I can't debrick my unit. Could you provide me all files (links), which helped you to brought it alive, please? Thanks.

Hello! At my unit, yes the buttons light was on. There is a link in my post and also you can read here: http://forum.xda-developers.com/showpost.php?p=68717214&postcount=877

Stuck at Android logo

After receiving my UL28N2 Joying head unit i managed to get root on the device according to this tutorial: http://forum.xda-developers.com/showpost.php?p=69648860&postcount=84
I bought this unit to be able to use Tom Tom on it. After first trying to install it failed and it says it was not able to get any connection to the Tom Tom service.
After that i found this tutorial to change the serial number and run Tom Tom: http://forum.xda-developers.com/and...lmight-tomtom-problem-solved-fw-mtcd-t3471075
It failed to install xposed framework. As last i wanted to installt he newest version of xposed found here: http://forum.xda-developers.com/showthread.php?t=3034811
I installed the xposed version and gave it root access to install the latest framework. From there it went wrong.
The device restarted and i saw the android logo (the green doll) after that the device rebooted again and now i am stuck at the android logo (white one).
I am able to get into recovery, used this tutorial for it: http://forum.xda-developers.com/showpost.php?p=69936773&postcount=4
Am i able to recovery it and how can i do this? I tried to copy the latest update from Joying to an usb stick and put the stick in when i am into recovery but nothing happens.
Hopefully one of you guys can help me with this.

Afaik there was no xposed available for the Intel units.
Try on the sdcard1 or the usb1. System should detect a new update

What exactly do you mean?
I tried to put the latest update on a usb stick and stick it in the device, boot into recovery but it does nothing.
Trying to start android with the usb stick attached does neither work.

I meant that ROm updates usually work only over sdcard1 or usb1...but if you tried....
Once booted into recovery can you select the option to restore/update from file?
Which options do you have?
Are you expecting that update file to be detected and installed automatically or did you try to navigate through the recovery options to update?

I do not see any options to select
Tried to follow this tutorial: http://forum.xda-developers.com/showpost.php?p=69936773&postcount=4
I made some pictures of what i see when i follow the tutorial.
First i see the android doll with some Chinese text without! and after a second i get another message with ! at the end.
I can press the home button and i get some red text with Error, wait here... or something like that.
I want to remove the xposed framework, after that android will run again.

I got a solution. Download the latest update from the joying website: https://www.carjoying.com/Joying-blog/59.html
Copy it to a usb stick that has been formatted as FAT32 and put it in the usb outlet that comes at the same side as the wifi antenna goes out.
Apply power and press the reset button. The device will so the same routine as updating. Wait for 20 minutes and it works again.
Perhaps this can help us further, if you don't damage the boot image you can always flash a new ROM with that usb port.

I had tried this same thing on Intel unit, let xposed framework pick which version, it got stuck on white android logo forever. I found putting my sdcard with the update files would work also without a keyboard. If I cut power to it and it failed to boot 3 times , on the fourth try it would show my car logo and in red letters underneath something like "failed to boot systemui after many attempts!" At that point it automatically searches sdcard or usb for the factory image to flash.
I too tried everything for tomtom go, but no success

My head unit that I buy is made in China. The hardware is like joying. I updated the android version 6.0 of joying, now my head has a "UI does not match" error, overlay screen and wrong resolution. Functions like radio, music ... working normally Can you downgrade to stock android 5.1.1? Can you please fix this bug or downgrade?

i have an erisin device, but when i was stuck on android logo, i had to reboot device and pull out both SD CARDs!
Afterwards it could boot into the system

Chinese screen after botched update. HELP!!!

I tried updating my PX5 (3188/32rom/2gbram) FUSE rom to a later version and now when the headunit reboots I get a black screen. If I insert the SD card I get a chinese screen with GPS. Backup camera still works. Also, can't boot into recovery. Is my unit bricked? Pic attached.

Is it an MTCD/E. What recovery options have you considered from the forums if MTCD/E

I had a recovery option (v8.0.5) but when the update botched I can't boot into recovery. MTCD unit. Haven't messed around with roms, recovery, etc since 2016 so forgive me for being rusty.

You have to pull out the sd card.

Yeah I figured that much out and when I do and th e unit boots up to a black screen and I get a message flash in the bottom left hand corner of head unit but can't read it as it isn't up for long. I left it be the other night, got in my truck the next morning and recovery was up but couldn't get it to recognize update.img from sd card. Now I can't get it back into recovery. Can anybody hep?

Take a look at my OTG thread. I've had 100% success via this method.
For users that aren't comfortable with this OTG method, I have received SOMs from around the world - all I ask for is return freight.
Some options.
