[Q] Possible Hardware Brick Issue - G Tablet Q&A, Help & Troubleshooting

My tablet will not boot any farther than the Viewsonic Birds screen. At first I thought this has to be a software-related issue. That being said, I've tried every single possible combination using nvflash to no avail. Today i decided to take a closer look into my tab and noticed on the docking station connector connecting to the system board, one of the wires were clipped. Now because of its position (fifth wire from the left) I at first assumed it came that way (not sure why I thought that but yeah...). Once I found a high-def picture of the tab's system board untouched I realized this was not the case and I somehow clipped it upon taking the tablet apart. I attached a picture of the one I found with a red arrow pointing to the wire in question here.

Does anyone know what exactly this wire is responsible for?
Is it possible that this wire being cut is causing my tablet to get stuck at "The Birds" screen?
Also, has anyone had any luck with getting their hands on any schematics or wiring diagrams of the gtab?
Has anyone done something similar to this, and how were you able to rejoin the cut wires (with them being such a small gauge)?
If this wire is the culprit (which I'm praying is the case, so I atleast know the problem), my best guess is because upon boot-up the OS goes through its checklist and once reaching the docking station connection, this wire being cut halts the boot-up process hindering me to go any further. That sound like an accurate assessment? I'm just trying to understand the issue as best I can.
Any insight would be greatly appreciated, Thanks!

I really don't see that as being an issue.
When did you open the tab up? Before or after boot issues?
Have you hit the internal reset button?
Have you double checked your nvflash files and stock image to make sure they are correct for your system/Gtablet?

Both, first time I opened it everything went smooth and started right up after back together. Second time was so I could put a dab of MX4 thermal compound on the tegra2 chipset, and ONLY on the chip; none on the board. After back together, it turns on but freezes at 'the birds'. During this whole thing, I had BoS 5.2a loaded.

Since this started, only every time Ive tried anything related to formatting (format all.zip), or nvflashing.

I have tried flashing back to bekit's stock (pre 4349, how mine came) and stock 4349 1.2 (since I was on a 1.2 BL at the time). Between every flash, I've hit the hard reset, ran the FORMAT ALL.zip, then preceded to nvflash.
Its also hard for me to believe this is somehow a hardware issue. Seems to me if it was, the tablet simply wouldnt turn on or I atleast wouldnt get a picture. One interesting thing roebeet brought to my attention was that eventhough it freezes at the birds screen, the little black bar along the bottom still pops up meaning the kernel is even being recognized, then it freezes. It would be nice if I could know the order precedence when this tablet is turned, as in the checklist the soft/hardware go through. Maybe that could help with narrowing this problem.
Anything else you can think of, please let me know cuz I'm almost at wits end.

Actually, weird things tend to happen in regard to hardware issues.
I had a laptop that I dropped from 3 foot up. Drag and drop function stopped working. Half my keyboard stopped working, but only for certain programs. Some boots resulted in the taskbar not registering until I control alt delete to bring up the task manager window. At first, I really thought these were all software issues. But after reinstalling windows for 3 times the same damn things kept happening.
So, yeah, hardware issues do result in weird software issues. It's like hitting yourself on the head with a hammer. It's a hardware issue, but you might end up a little cukoo afterwards.

Yeah, hardware issues like that I'm accustomed to having 15+ years experienced working on/building oem/aftermarket systems and being a pc technician by day. But this issue is getting harder to believe it is hardware since A)The wire accidently cut belongs to the docking port and B)The symptoms its exhibiting are the exact same symptoms I've experienced with my tab in the past before opening it at all. But with that being said, I dont know what else I can try on a software level.
One thing I thought of last night that I'll try sometime today is just trying to install bekit's stock 1.1 ROM from my external sd. Read somewhere that the internal sd has gone bad on some gtabs. Dont know if this will work since nvflash seems to flash properly, it just doesnt reboot and I dont know what else to do at this point. Thanks for your input though.

[Q] Screen turn blank White) ob G tablet

I had my Gtablet for a week and after the update, it works fine. Today, when I power up the tablet, the screen just went blank (white screen). I am a novice thus I did not mod the tablet. What happens? I hate to return the tablet since I was starting to enjoy it. PLease advise.
You might try to reload a working firmware. If you have clockworkmod, and a saved image, restore it and see what happens, perhaps a driver got corrupt somehow. If that does not work, it may very well be hardware failure. Take it back to Sears a white screen is just that. Not useable.
Thanks. Guess I need to run over to sears again for another exchange.......This was my second one. The first one just doesn't boot up and this one was working fine until now.
I am having this white screen of death issue. I'm hoping that getting the battery completely drained will reset something and allow me to see the birds again...never thought I'd be wanting to see those birds, but here I am.
Has anyone ever had the blank white screen of death and gotten their gtab to work again?
damn it, same thing just happened to me. I left it unused for 2 weeks, now I turn it on and white screen! not nice
Bump for the sake of my gtab? anyone??

White screen follow-up
I believe that this "white screen" is the equivalent of when you see a "No Signal" notification on your HDTV. I'm pretty sure that the tablet is running fine, it's just not outputting video to the LCD. I didn't have a dock to do video out to verify this, but I am fairly certain that's what was happening here.
I had to RMA mine. If anyone has other results/info, please let me know.
The first gtab I bought when it started had a white screen that you could hardly see anything and it blinked. I took it back to office depot and got a new one.
Follow-up White Screen (more info), using HDMI output
Have the same problem with my second GTablet. However, I bought an external dock that has an HDMI output for the GTablet. With the working GTablet, when I plug it into my television, the television mirrors the output of the screen perfectly. With the white-screen tablet, only the television shows something. As I am a basic hardware guy, I guess there are two reasons for this:
1. The flex cable between the display and the computer is loose/broken.
2. Something in the electronics is wrong.
I have received an RMA number for this problem from Viewsonic, although they may just look at it and send it back to me. Any other experiments that people want me to try while I can still see on the external?
Otherwise, I'm just gonna send it to Viewsonic in a couple of days and wait 15-20 business days.
G Tablet White Screen
I have had this lately too. Once in a while when i turn my Gtab on the screen is white. When it first happened, i assumed it was bricked. I tried doing a update.zip back to stock...nothing...just white screen. Then when i was in the process of doing the update.zip flash again, i bumped the bottom, right corner of the tab on my desk and the screen all of a sudden when back to normal, showing the home screen. Now, if it does this white screen business, a simple tap on the right side usually brings it back to normal. I would also assume this is a loose connection of some sort. Anyone cracked the gtab open and been able to find where the screen connection is located? I bought my gtab Jan 14 2011 so it is out of the return window to Sears, and i haven't called Viewsonic for assistance yet as i fear i won't get very far with them. Any help is greatly appreciated!
Triple Love Tap Fix on Bottom Right Corner for White Screen Fix ... Back to Normal
After reading the last post, I tried a triple love tap on the bottom right corner on a white-screened g-Tablet, and voila. It's working again. The Internet is a grand thing. This love-tap thing is clearly undocumented Viewsonic security feature.
As for reference, I did break it open and tried to figure out where the flex cable went, but it's a pretty tight SoC design and when I removed the cover, the connection seemed to be sandwiched between the motherboard and the touchscreen itself. Not wanting to remove the 5 various cables and 3-4 various buttons floating around, I gave up at this point.
If I have to periodically do a love-tap, well so be it. At least, I'm not spending $600 for Motorola Xoom. Thus is the fate of cheap bastards like myself who like to play Fruit Ninja on the cheap.
I can't believe this worked!! "Love Tap" to the right corner brought my white screen back as well.
Bump really works, thanx!
i can't believe the bump worked. I took it apart and looked inside at every connection. I was about to throw it away and then i found this post. I did the bump and it's back to normal.
Another "love bump" success!
Just had it happen to mine this morning -- blank white screen. I did a love bump as suggested, and the screen is back! Definitely sounds like a connection issue, but I don't recall bumping it before it blanked out. I'll just keep fingers crossed that it doesn't happen again.
BTW, for anyone else who needs to do this -- it's definitely a "bump" compared to a "tap". I had to give it enough oomph that I could have craked a walnut with my palm under the same force. Not a "whack" but a "bump" compared to "tap"
WTF WITH VIEWSONIC/USMERCHANTS! I Live in Mexico, I sent (paid..) my tablet to the US for warranty (white screen, the tapping doesnt seem to work with me..) they recieved it, send it back to a friend in the US and he sent it back to mexico (PAID AGAIN).
Just recieved my gtablet, turn on, white screen, nice they didnt even touch the friggin thing!
WHAT THE F...
Ok, bumping this thread again, and letting you know.
Since I was pissed, I opened up my gtablet! Well to letting you know, the CONNECTOR that goes FROM the motherboard to the LCD...was completely loose and not completely connected. This has to be a factory fault, since well, its almost impossible for it to disconnect! Anyway, My tablet is working just fine now, (after 4 months ¬¬)....I will try to get my shipping money back from US Merchants, bastards.
RAWR!
[REQUEST] A permanent solution than periodic love "tap/bumps"
Can you post a picture of the connector? I broke open my tablet before, but I was unable to locate this loose connection. Although I find the current solution very amusing/charming , I would like to have a permanent solution on this thread.
For long term care of the tablet, I've had to do this solution about once every 2-3 months on my 6 year old son's tablet. He had the tablet with the original problem and he may occasionally drop/jostle the thing more than I. So, for the lifetime of this product, the love tap/bump may be an acceptable solution. However, it is clearly a loose connection problem, and more information on your solution would be very helpful to the community.

I draw a Red Square in the "affected part".
In the top of the square is one end of the cable, in my case this was correct. The other end is underneath the motherboard, so you have to take out all the screws for the motherboard to check the other end, this was completely off.
I dont know if this will help everybody, because I gotta say for myself, the bumping in the bottom right didnt worked for me, not even once and I SMASHED the thing really hard!

edit:
BTW, US MERCHANTS warranty told me someone screwed up on their side, I should have gotten a new tablet ¬¬. Anyways, I'm trying to make a deal with them, since I paid like 50 dls for shipment (I live in Mexico..) and they didnt do anything. Will let you know maybe I get a free dock!!!

[Q] Car Mode?

For the past day or two my phone has been enabling car mode.
I haven't made any major updates in a while either. What is really pissing me off is that it's disabling any sound coming from the phone and it is closing some apps instantly. It is happening whether my phone is plugged in or not, and if i want to use the phone for storage over usb and car mode decides to activate the computer claims it has been disconnected though the phone says it's still charging.
Is there any way to get rid of it? I don't have a car, or any sort of dock for the phone. I really have no use for whatever it was meant to do and I'd really like it gone...
Any ideas/suggestions?
I never had a problem with car mode activating at random, however I hate car mode and the Google car app with a burning passion, so what I did is...
- Uninstalled the Google Car Home app via Titanium Backup
- Downloaded (and subsequently purchased) the app NoDock. NoDock prevents your phone from going into car mode altogether, and its saved me a lot of frustration. I think its $1.99, but don't quote me. There's a trial you can get first for 7 days, I'd recommend that.
That;s obviously a road requiring you pay to fix the problem (and it might not even...) However, if your phone is acting abnormal for no reason, ie you haven't neglected it or played soccer with it, then vzw should replace it... But I have no experience with that, so that's all I've got for ya, sorry! Best of luck.
I looked for the trial version ad it doesn't seem to be out there anymore... The full version still advertises it as to use the trial before buying, but I can't seem to find it...
At this point the phone isn't making any progress charging and it is continuously connecting/disconnecting from the computer...
If it doesn't start working might have to un-root and bring it in >.>
my tbolt lately as well activates car mode when i am in the car but i hate it and want it dead... it happened after installing gingeritis.... but it also did it on das bamf gb... i refuse to give up my gb so i will execute the app!!

Well, deleting Google's Car Home app will prevent that from launching, however, the Thunderbolt itself has a "car mode" that it will enable when the dock trigger is activated. So, unfortunately, simply deleting the Car Home app might not solve your entire problem, but its worth a shot nonetheless. Also, I'm not sure that NoDock will work with a GB-based ROM, but that, too, is worth giving a try!

In all honesty, if its not even charging anymore, un-root, wipe, and nand that puppy and send 'er in. I know that the TB is unique in that it doesn't use a magnet to activate Car Mode like previous HTC phones, but instead it uses (to my knowledge) a short in the USB slot to decide whether the phone is docked or not. So problems with USB mounting, charging, docking when not docked, etc. would seem to indicate that you have some sort of problem with the port itself. That's just a shot in the dark, but man, I'd have sent that in yesterday
And as for NoDock, I just looked, and I can't find the trial either
To some extent it is still working. It isn't getting any charge, but if I unplug the phone it turns off almost instantly. Seems like it will be hell to move the stock stuff over to the phone to flash it, but looks like that's what its come to... Guess I'm bringing it in tomorrow...

If you have a friend with a smartphone or even any kind of bluetooth-capable storage device, you could send the files to yourself via BT... It may not be the fastest, but it might save you some major frustration. But yeah dude, that sounds straight messed up. Best of luck.
I just put the sd card into my laptop to transfer. Back on stock (feels soo different...) No more car mode... But the phone still isn't charging... Until I can bring it in I guess I'll make the phone look like it isn't brand new again...

Either way, as far as I know, VZW checks for two things:
1) Obvious evidence of negligence and/or intentional damage
2) Something I don't remember that has nothing to do with root
So you should be in the clear, if anything just say you did a factory reset yourself to try to fix the problem
Well as it did when I rooted it, it recovered all of my apps w/o me having to do anything. So the phone already looks the way it did before excluding homescreen stuff and an empty inbox/contacts atm. And the most damage there is, is a small scratch where there was already an air bubble on my screen protector. If they would have ever made a case that fit the extended battery that probably wouldn't even be there =o

Haha yeah I feel you on that one. I think the type of negligence they look for is more like a mangled looking device with the customer claiming innocence. You should be fine in my opinion.
hmm... just woke up, about to bring in the phone, which did manage to charge overnight. noticed i still have a rotating rosie and it looks like i'm still undervolted as my kernel was doing earlier. well neither highly noticable as bad things... and car mode did come back today so, i'll be bringing it in now...
Go for it bro, I really doubt they'll check for little stuff like that, especially considering the bigger issue of car mode and your charging problems. Good luck though!

Unable to get out today, so I've been looking into other options for now.
This seems to be what it's used for though I've never been given these options when the phone goes into car mode. The icon shows up in the notification bar identical to the picture.

On the VZW site these are their solutions. (none worked for me being there is no water damage and the port looks fine from what i can see, still gonna have to bring it in...)
Maybe this can help someoneelse if anyone runs into this problem or bring more options to try to help me fix it.
From what I can see, the first picture is of HTC's car home application, as opposed to Google's. When your phone enters car mode, the default action is to launch one if those applications, unless you've manually removed them. The fact that your phone enters car mode but launches nothing is abnormal in and of itself, not to mention the fact that it shouldn't be activating car mode in the first place.

I did manage to make it to the vzw store and they were surprised to see car mode on the phone at all. The lady at the store took out the battery, restarted the phone and concluded that I would get a replacement after the bill that was just paid like yesterday clears with them.
Good! Hopefully all goes well and you'll have a functional device soon

Touchscreen Calibration Issues (You Might Have This Issue As Well) [Updated 1/4/2012]

Original Post:
Just discovered that my prime is almost an index finger off in accuracy around the inner 1" edge of the screen. Causes me to keep missing the search button in the browser, it registers me clicking the bookmark button instead.

What the problem is:
The touch screen's calibration is off while the device is plugged in and charging using the provided stock ASUS charger. (No other chargers have been tested so far)

Test Protocol By N11:
Navigate to Settings/About Tablet/System Firmware Update
Try to tap "Check Update" while charging and while unplugged
Report any differences. Also report your version information.
Test Protocol 2:
Download "Touch Test" or "Multi-Touch Benchmark"
Report any differences while charging and while unplugged. Also report your version information.
Edit 1: I have discovered that this only occurs when the device is charging... Weird. Can anybody else try this? Download "Touch Test" and play around with in while charging and unplugged.
While Charging/Plugged In:

Same thing is happening with mine, but I cant hit the refresh button on the tabs in the browser (instead it keeps clicking the close button). I even tried my targus stylus and it still doesn't work.
I had a very similar problem with mine only it went much further than just what you guys are experiencing. In addition to what you stated, mine wouldn't even register anything at random intervals and in random spots on the touch screen. Here's a little video of just some of it http://www.youtube.com/watch?v=oywWUxPMeX8
I feel for you guys. I had to send my back. Currently awaiting a replacement.

has something to do with the voltage of the charger my epic 4g touch did the same thing with the wall adapter it came with started using a different charger from my old phone and problem went away...... I would be curious if all stock wall chargers for the prime do it or just some?
This is interesting. I had a Dell laptop with a defective charger and the touchpad would throw the mouse all over the place while it was charging.

Guess this is going back to best buy...
I think it has something to do with the backplate tingling/improper grounding,
throwing some static at the touchscreen grid making it think its being touched elsewhere.
See howfar off the touch dot is at various places on your screen.
You should be able to figure out a trajectory to where it is making "contact".

Exactly, try turning around your charger (so turn it by 180°)
I had something similar happen on my DInc when I plugged it into the wall and car inverter using my brothers Motorola cable and charger. The phone will just go wonky with the touchscreen. As soon as I unplug it everything would be copacetic. Try another charger and or cable.
So i wonder if its more likely that my prime isnt the problem and my charger or home wiring is wonky
I noticed this yesterday where I could not close browser tabs. Eventually I got the tab to close, and thought this was just some dust on the screen or something.
I have not had any issues before and use it a lot while charging (its technically my wife's so she gets to run the battery down and I get it after since I sit close to a outlet), and I was not having issues at all until the last firmware update (not that it is necessarily related).
I will try and run some more tests this evening and see if I can produce. I would think if this was a hardware issue I would have run into it sooner.
Did anyone have this issue prior to any of the latest firmware updates?

I'm honestly not sure. Prior to my device arriving yesterday, I found out about the newly released root method for the latest OTA so I upgraded as soon as I turned on the device. I do not have a benchmark for comparison.
I will be trying to invert my charger and I will also be trying a different location across town to see if maybe my electrical wiring in my home is causing voltage noise/grounding issues.
I have a solution:
Code:
if (Device.isCharging) { Screen.Touch.setOffset(-5,-10) }

Touchscreen Issues

My Atrix seems to have a significant problem hopefully someone can help with. I dropped my phone and my screen had some issues when touching certain areas (ie. It wouldn't register as a touch during any app in certain parts of the screen)...so I replaced my LCD and Digitizer, and no luck, similar issues. So today I replaced the ribbon cable with a new one(with power button, front facing camera etc) ,and STILL the same issue.
I've tried new Roms, and done fresh/clean installs of everything but I've no idea what else I can now do, please help?

Although it doesn't make much sense, you may need to try the PDS partition fix. You'll need to google that and find the files and tutorial for fixing it.

Here's the pds thread. Maybe it'll help. http://forum.xda-developers.com/showthread.php?t=1131649
Update
Hey really appreciate your quick response to the issues I'm having.
I have tried PDS Partition Fix and unfortunately this hasnt helped ... both methods were followed to the letter and nothing the same issue applies.
Dont suppose there are any other suggestions that anybody can come up with?
I am thoroughly grateful for all your help!!

Only other thing I can suggest is warranty.
when you replaced the lcd and digitizer did you clean it very well between them? I have seen the slightest amount of dust disturb the digitizer, also when holding the phone upright is it the "e" "s" "d" "x" area of the keyboard that is acting up?
Moreover
Unfortunately, the warranty is now void since unlocking the bootloader, which I knew was a risk. I cancelled my insurance too since the policy excess was ridiculous.
When replacing the digitizer I cleaned the connectors using a microfibre cloth, the ribbon cable connecting the digitizer to the board was also replaced, so potential board connector issue?
Its random, what works...if the screen was in quarters from top to bottom then quarter 1 and 3 do NOT work...so i cannot pull down notification bar unless I rotate screen, and use a working area of the touchscreen. But thanks to Go Launcher I have set up a swipe gesture for notifications. And thanks to perfect keyboard I can change the height of the keys so I can at least send a message. But this isnt ideal, since the keys are so small.
Any other thoughts on how to clean the connector properly or anyone experienced the same?
the digitizer connects to the speaker ribbon cable and then goes to the board, but that ribbon cable usually doesn't get damaged.
you can reflash a vanilla 4.5.91 and possibly not brick and if it comes back it wont show the unlocked text I don't recommend this due to some people experiencing hard bricks doing it. But then you might be able to return it.
you say its random, so does the entire screen work sometime? or is it always quarters 1 and 3? if its not changing I would say its a bad digitizer.
Well I've tried 3 different digitizers so I know this is not the issue.the change of ribbon cable was merely a stab in the dark. Its random the places that doesn't work, but ALWAYS the same places work/don't work...so quarter 1 and 3 DON'T, but 2 and 4 ALWAYS do.
How might a reflash work? I'm 99% certain this is now software related...my only other theory is the mainboard may be damaged in some way.
Reflashing may be an option, this is my current set up...I've upgraded the radio so whether this will cause issues I've no idea ...

it won't fix the problem but it is a way to remove the "unlocked" text from when you start up the phone, or are you completely out of warranty / no chance to return ?

[Q] Scrambled Screen/display

I've been facing scrambled screen/display off late. Occurred thrice past week when I was browsing in chrome and while watching videos on YouTube. It just occured after 10~15minutes of use. Never occurred while I was gaming. (Only play FIFA15 occasionally). I'm much worried as this may brick my device. No sure if my GPU is the real culprit. I'm running lollipopalooza 5.1.1 with no extra kernel. Have this issue only after I installed lollipopalooza. Should I flash stock and check the issue with google service center. Kindly help!

Your nexus is defective, just return it to stock if you can & get another one. No point in trying temp fixes for a hardware defect, besides it's under warranty so HTC won't give you trouble. Another user had this problem & I think they returned theirs for another.

Mine was doing this last week, reflashed factory image, did a factory reset as well and not done it since. Not convinced it's a hardware fault unless it starts doing it again after the wipe. Been 4 days without any issues, wouldn't go more than a few hours without getting it before.

Hate to say it, but im convinced it is a hardware problem/failure. My N9 started doing it 6 months after I bought it.. N9 would freeze even with fully stock(factory reset) kernel/ROM, and even happens with tablet in safe mode.. The freeze/crash prerequisite conditions are:
1. Battery less than ~20-30%
2. Connect charger(may or may not cause/create the condition)
3. Browse the web on Chrome (or do some cpu /GPU intensive task to heat up the device)
I'm not 100% sure these will make your tablet freeze, but my tablet became progressively worse within a month of it beginning to happen, and freezes began after I started testing kernels and ROMs for a month or 2 (I ran the tablet stock for first 4 months without any issues)
HTC rma'd my device.. Claimed they changed the mainboard.. Been using for a month now, on custom kernel/rom, and device hasnt had a scrambled screen crash/freeze [knock on wood] !!!!

oh joy, this looks identical to the "nvidia defect" (look it up) my new 2000$ laptop had several years ago that they refused to fix, where the gfx chip would literally fall off the board if it got too hot because they used tainted soldier and junk cooling setup. oh please I hope this is not the case again.

Just unplugged the power cord from the main board and plugged it back.
This is the exact guide and steps I followed https://www.ifixit.com/Guide/Nexus+9+Rear+Facing+Camera+Replacement/36892 (except step 3 and 5 which I skipped completely)
I have fixed 2 tablets.

Looking for this exact issue with screen scramble and thankfully found this post despite age of the thread... So when you say you unpligged power coard from the main board, which steps do you mean in that ifixit guide? and you have any idea why this solved it?
I'm about to throw mine away. Google and HTC wouldn't fix mine being like 15 months old last time I checked. Got it at launch. I got sick of playing phone tag and complaining. It was a good tablet for the first year before it started overheating instantly at every use.

Yeah. This problem happened to my first N9, luckily I got a replacement from HTC. Now the screen in the replacement is going bad (discoloration, really bad light bleed). I was thinking of buying the HTC manufactured Pixel to replace my aging LGG2, but if the N9 is indicative of HTC build quality when working with/for Google, no thanks.

Just wanted to say I had the exact same problem. Tried factory resets and everything I could think of and none of it worked. Gave this a try, popped the back off the nexus, disconnected and reconnected the battery cord and now everything appears to be fine. I've been taxing my battery, playing videos and games and ran it down to 40% with no crashes. Thanks! I never would've thought to try this and am still not sure what it fixed, but I'll take it!

I did as what you've said and it worked. Thanks a lot. But today, which is 20 days later, this **** happen again. So I just repeat. Damn it, this is the reason why I don't give a **** on HTC-Made Pixels.
Figured i post here to say i had similar issue for a while now
Bought this tablet when it first came out... Wasn't too impressed but i already promised my n7 to a family member... Eventually got a shield tablet but never got rid of this one but use them both a fair amount
About a year ago the tablet really started to slow down a bunch, and i don't keep much on here, mostly just use it for netflix and YouTube
Occasionally a rom/kernel change or full wipe would fix it, but it always slowed down faster than anything else
Around 6 months ago (maybe don't remember when) i occasionally got a pure white screen or the scrambled screen and would have to hard reset
About a month or so ago i researched it, found out about the battery trick and did this, hasn't happened since. Not only this but tablet has become far more responsive (never been buttery smooth as one would think it should) like day one and has stayed this way
Even doing full wipes and new rom/kernel wouldn't make it as snappy
Also i noticed that one of the wires going into the harness was a bit loose so i snugged it in tight
TL;DR:
For those with the scrambled screen and those with slow response tablet - open up your tab and remove battery terminal, check the wires and contact points, reassemble
Now you should be golden
Disconnecting and reconnecting the battery worked for me.
Watching “How to Replace Your Google Nexus 9 Battery” on YouTube helped a lot.
Didn’t have a spudger. I tried a guitar pick, but my plastic putty knife came in most handy.
I agree with LC that it is probably a battery issue as the same thing happened to me a couple years ago. Reconnecting the battery was a temp fix but replacing the battery solved it.
Good luck finding a new battery as supply had dried up.
