[Q] Just got dock. Keyboard not working at all

Only the keyboard is not working. No keys function at all. Only thing it will do is wake up the TF if I press any key. Touchpad works fine, as well as charging. Haven't tried any usb or sd cards yet.
It says it's docked and hardware keyboard is selected. Tried rebooting with an without the dock, and removed and reinserted the tab many times.
I'm rooted and running the stock ICS ROM and did the US Update to get it to be recognizd by my pc, applied through CWM.
I've tried wiping all data through CWM, wiping from the power+vol down method, and cold restart.
I also get a notification that there is a firmware update available if I check, but when I try to apply it just gives me the exclamation point and I have to restart the TF.
So I'm thinking the KB needs a firmware update? It says EP101-2013 right now. But how can I update the firmware while being rooted?
Any help would be appreciated.

Well I tried flashing the Revolver ICS rom with no change to the keyboard dock.
So I guess I'll head to a Best Buy tomorrow cause I think they still have TF101's on display. Will see if their display unit works with my dock or if it has the same problem.

Do you use asus keyboard in the input settings?

Yes it was set on Asus kb initially.
I've tried changing from Asus to Android, switching languages, turning off/on all the kb settings and toggling hardware kb on/off to no avail.
Also I tried the usb ports and SD reader and they work, so my dock is 100% functional besides the actual keyboard

You may want to try updating the firmware for the KB. I know I had to do that before mine worked correctly.

How do you update the kb firmware?

Well just got back from Best Buy. They had two TF101's on display, an open item running honeycomb, and another running the latest ICS firmware.
My dock keyboard worked with both of them perfectly....
So guess I shall now try unrooting and going back to a honeycomb version, then maybe try an OTA ICS update or something. Probably won't work, but I need to unroot if I send it in for warranty anyway.
Anyone link a good way of returning to unrooted honeycomb?

Damn. Flashed a stock honeycomb rom, flashed stock recovery and did an ICS update removing root, still no change .
So guess it is warranty time unfortunately.
Quick question before I send it in though: Now when I start up the TF while holding vol dwn+power, it asks me like usual about pressing up to enter Recovery. When I do this though it just goes to an android with red exclamation.
Is this normal or not?

Update:
Received tablet and dock back from Asus Service center on April 5.
Good news - Keyboard was working with dock!
Bad news - lower right quadrant of dock touchpad is now completely dead. Was not like that when I sent it in. Other portions of touchpad act erratic, as though your're tapping to click on something when you're just trying to move the cursor.
That part may just be due to when your finger transitions from the dead quarter to the good parts.
Sent dock in for RMA again yesterday.
Really bad news - Had not really played with my tablet until yesterday, and not at all with the dock disconnected.
Now with the dock gone and when the tablet is not charging, it just constantly reboots, or sometimes shuts down as soon as it goes into deep sleep, I believe. About 1 minute turning off the screen.
It's just in a constant loop right now. Turns on, screen goes off due to inactivity, goes to sleep and reboots instantly. I've wiped it like 8 times, cold reboots, disabled everything/changed options, skipped all steps in the setup and didn't even enable wifi and it still does it.
Called and got RMA number just now. I'd try rooting it again, but I'm not 100% sure the issue with the touchpad is from the dock, so I may have to send them back again if they come back not working together once I get them back.
FML.

[Q] Everything on my note 10.1 screen looks like a film negative

My 2 1/2 year old son was playing with my Galaxy Note 10.1 tablet and seems that he change some settings on the tablet because everything (wallpaper to widgets to apps) all look like film negatives. Even Youtube videos have that effect. How do I get it back to the regular look? Do I just do a factory reset or is there other steps that I can go through without having to do the factory reset?
Thanks in advance for the help!

Go to Settings > Accessability and uncheck Negative colours.

Thank you so much. I am still trying to learn all the functions of the note 10.1. Now I can go to bed :laugh:.

No problem, glad to have helped

If you like to use it often, for any reason, there is a widget "negative colors", it's one click instead of going through settings.

Possible issues causing color inversion.
I see that this thread is almost 3 years old, but I wanted to offer some possible explanations and solutions to this issue.
There are 4 problems that can cause the colors on the Galaxy note 10.1 to become inverted or distorted. Settings, LCD flex cable, Display drivers, and the LCD itself.
First check settings (Settings>Accessibility>Negative Colors) and ensure that this is disabled (box unchecked).
If this hasn't solved the issue, then carefully open the back panel of the device, and ensure the the LCD flex cable is connected properly. YouTube has several instructional videos available.
If the issue persists, then perform a back-up and restore to factory settings. This will reinstall the display drivers.
Lastly, if all the above has not solved the issue, then replace the LCD or contact your local repair facility.
Anything beyond these would indicate a problem on the mother board.
I hopes this helps someone out there save time and money.

I'd like to thank you for this post. I was having issues with the color calibration and artifacting on my note that started one day for no reason. I followed the troubleshoot order you have posted here and found out the LCD connector had worked its way loose. So I split the case and re-sat the connector and now everything works great. Thanks for saving the $100 screen replacement cost.
Most Sincerely,
A poor college student

color issue after screen off
My Note 10.1 2014 (P605) is ruining smoothly for 3.5+ years without much trouble. Now, it's screen is giving some color issue. Tab boots fine and colours shown correctly. Once screen is off, it start to invert (not sure whether the correct word) colours. Later I observed screen not switching on but accepting touch commands.
I tried color invert setting, it seems not effective. Flex cable was not loose but sometimes reconnecting resolved temporally. Re-flashed the OS but issue came up after few days. This may seems like screen fault, but screen working fine at boot till screen off.
Does anyone have similar experience or advice to help me out.

I have the same problem but I don’t have the solution. The color is ok when I turn it on after the tablet power off but the second on the colors turn To light red

Nexus 5 freezing, screen acting up, camera unresponsive, WiFi stuck on 'turning on'?

Hi all, new member here, so apologies for any mistakes I make.
A friend of mine has passed on to me his Nexus 5 (2013), stating that there were a number of issues he was having with it. After using the device myself for a couple days I can confirm that the following issues are present:
- The screen will sporadically freeze and become unresponsive to any touch input, and the only way to solve this is to lock the device and unlock it again. The time between instances of this is random.
- The screen will occasionally cut to black, but the display is still active (i.e. you can only see the backlight). This happens for a number of seconds before returning to normal on it's own.
- The camera is completely unresponsive/broken (See picture 1 below). Possible loose connection?
- The WiFi is stuck on 'turning WiFi on' in the settings, and stuck at searching for networks in the notification bar(See pictures 2 & 3 below).
The device was dropped at some point in the past, but the damage is typical (See picture 4 below) and I see no immediate reason why this damage should cause these issues in particular, but I'm by no means an expert, hence why I'm here. =) The device has only been dropped one time, and has not suffered any other damage, including water damage.
My first instinct was to boot into recovery mode (where it should be noted that the freezing and display issues I mentioned above didn't occur, leading me to believe it is more of a software issue?) and clear the cache partition, which did not solve the issue, and neither did a full factory reset.
So, with all that being said, what would you guys suggest? Should I try flashing the factory image to see if that works? Rooting? Flashing a custom ROM? Any suggestions would be most appreciated!
If you require any additional information let me know and I'll happily oblige.
Thanks in advance guys!

It could be the motherboard or screen. You won't know for sure until you replace one or the other.
The wifi chips do fail on the Nexus 5. I a motherboard that also tries to turn on wifi but turns itself off after a few minutes.

My first thought was that it was a hardware issue to begin with, but due to the sporadic nature of the issues (excluding the camera obviously), and the fact that it didn't happen whilst in the recovery menu, I'm more inclined to believe it to be a software issue? I could be wrong of course, I'm just wondering if it's worth flashing the factory image on to see if that solves the issue?

You may as well flash the stock image and see what happens.
The lines showing on the screen does not look like a software issue to me.

Those lines are what appear when I open the camera, they're not there otherwise. THAT is almost definitely a hardware issue, granted.

I have a Nexus 5 that has the wifi issue. I flashed a bunch of different Android versions (like Android 7 and 6.0) which none have worked. At one point I opened my Nexus 5 and left it like that for about a month, then afterwards I assembled it back together and the wifi worked for a little bit and then went back to its broken state. I've concluded that it is a hardware issue since data was working fine and was the only way I could get internet on my phone.

Hmm. I have to be be honest after looking online it appears that wifi failure is a somewhat common issue on the Nexus 5 devices. It has to be a hardware based problem it would seem.
Thanks for letting me know, I appreciate your input. =)

Note 10 Lite's screen stops working after some time

I've had a Galaxy Note 10 Lite for some time now and it started displaying this behaviour where the screen stops working after some time of the phone being on.
There's no apparent connection to how hot the phone is.
I've also re-sat all the straps and cables and cleaned them with isopropyl alcohol.
Sometimes during use, I'll see some quick greenish/purple-ish glitches on the screen. But, apart from that, it'll look amazing the whole time.
Also, sometimes, as I use it, the screen will freeze during whatever is happening on the screen and the image will refresh if I press it down on the 2/4 area from the top down.
Then, if I leave the phone for a few minutes with the screen either on or off, I could come back to it being unresponsive. At first, I thought it was turning off. But if I press the screenshot buttons, it'll vibrate and save the screenshot that I'll be able to see after I soft reset the phone back to life (it'll reboot by itself from time to time, though).
The time it takes for it to "die" varies from seconds to minutes to hours. But it's become unreliable and had to buy a new phone.
I thought about replacing the screen, but it costs as much as a new phone here in Brazil.
What I'm thinking is maybe there's some cable or something I could access on the screen to inhibit this behaviour.
Can anyone help me out with insights?
Cheers,
Uriel

Try in safe mode.
Clear system cache.
Try a hard reboot.
Any uncased drops or water exposure?

Just tried safe mode and the screen started all messed up, with elements that should be organised scattered all over it.
Now... I'm soft rebooting it and it goes straight to a dark screen after showing the Samsung logo.
I was going to try clearing the cache next, but now I need to get access back to the system.
I've done a hard reboot to no avail.
It was exposed to water years ago, which resulted on a screen issue that was fixed by Samsung by replacing it.

Ok. I got safe mode successfully activated now. I'll give it time but I don't feel too optimistic about it.

May have water damaged ribbon cable contacts, or water damage on the mobo is now showing up; corrosion never sleeps. Maybe another display failure. Maybe a loose cable; carefully inspect all display cables on both ends and their sockets. A failed ribbon cable.
Finally a corrupted rom or user data partition.
These phones are relatively inexpensive now, even new ones can still be had. The N10+ be an upgrade if you like it. If repair doesn't work you have other options.
The newer Samsung's suck. This generation of Notes was the zenith for Samsung and the Note... in my opinion. I have two N10+'s and they run like bats out of hell. Solid, well built, work horses that just keep running. This one in my hand has over 8k hours on it, looks, feels and runs like it's new with one battery replacement. Zero display flaws, current load is over 2 yo, still fast and stable with minimal maintenance. That's what these phones are capable of.

Never know, could be a 3rd party app.

So, this happened. And it rebooted right after I stopped recording.

Yeah looks like the display but you won't know what it is without opening it up.
Don't think a factory reset or reflash will help... I could be wrong.

Yep. I'm pretty sure it's a hardware issue.
I don't know how to get access to the other end of the ribbons that go into the screen, though. I'll see what I can do.
Cheers!

Watch some tear down vids. Have the right tools and take your time. With used ones going for a couple hundred that's another option.
I'm surprised how well my N10+ has held up, it's always cased. Water exposure is a killer. Even if it's IP68 rated, keep it away from water, especially salt water.

I hope is the backlight issue on the logic board

Huge battery drain problem on stock device

Hello there!
I'm having problems with this device, the Mi 10 Lite 5G (Monet) in particular.
Out of nowhere it started having an insane battery drain. To the point that if i unplug it from the charger before i go to sleep so the phone starts at 100% battery, when I wake up between 6 and 8 hours later, I find it at 30 to 50%, at an average of 7-8%/h.
I'm on all stock: latest MIUI, no bootlocker unlocked, no root, ironically I chose this device 'cause i didn't want any headaches.
Remembering my olden modding days, I remembered about the wakelock hunts, so that's the first thing i thought about. I tried multiple apps to do so and even the Battery Historian tool via a bugreport. Everything points to some kernel wakelocks that pretty consistently activate, not letting my CPU sleep at all, which makes sense as to why It would drain battery like that. The problem is I can't figure out what causes it. There's no app that does it, it seems to be all kernel stuff, I even factory reset and tested without installing anything. Either it's something with the system itself, that I can't quite pinpoint, or i'm starting to think it might be hardware. I don't wanna sway anyone, but my best bet is it could be a faulty usb-c charging port. Although I don't know how it could make it this bad, and I'm obviously not sure it even is it. Would suck to change it, spend money on it, and still have the problem.
Aside from the wakelocks, there's also another bit of info that makes me think that: when off, if i plug the usb cable in to charge it, the phone doesn't get to the battery charging animation, but it keeps showing me the Xiaomi logo screen, over and over. I haven't tested if it actually charges in the background or not, for fear of making things worse.
I even checked if there was something weird in the hidden battery stats by dialing the code *#*#6485#*#*, but aside from the phone going into "sink attached" mode at random intervals, which apparently means it's trying to provide charge to something else through the port or wireless charge (that this phone doesn't even have)...? I can't tell if there's anything weird with it or not.
I know my way around android a little bit, but I'm a little bit lacking when it comes to intricate information like this, and I couldn't find any information about this (these) particular wakelock(s) and everything else around 'em.
I'd really appreciate it if someone who knows this kind of stuff better than me could help me out with it. Even just to know what the problem is and there's no real solution.
I'll attach a couple screenshots from Battery Historian (my phone's been factory reset, so I have no apps on it, and don't plan on putting any on aside from the ones I absolutely need, in case I have to send in in for repairs, or root/mod it to try and mitigate or solve this) and alsothe bugreport itself, in case someone needs to look at it in detail to try and sniff out the problem.
Also, if this wan't the right place to post this, let me know. I went for the device, but maybe there's a better section to more in general help with these types of issues, but if there is i couldn't find it.

Thanks in advance to anyone who even only just thinks about helping me out!
EDIT: For anyone reading this, the problem was indeed a broken usb-c port/module. I bought a replacement and swapped it out myself and my battery is back to being perfect. Well, almost perfect... This quickly discharging business has lowered its health obviously.
I suspect some sort of short would make my phone believe something was continously being inserted and removed into the usb port, so the CPU would keep being woken up, and kept consuming extra power to try and read something off of it.
I hope this helps someone!

From what I can tell there is no problem. The battery is being consumed at a normal rate by the cpu, wifi and Bluetooth. If you're not using them just deactivate them.
Check the USB port for fluff etc stuffed deep down by repetitive compacting. Use something pin like but not metallic to scrape any foreign objects out.

While it does appear that it is being used normally, that graph stays the same if i turn everything off, either through airplane mode or by manually disabling wi-fi, bluetooth, GPS, or anything else. I can't turn off the CPU, so there must be something that keeps it up and running for no reason while it should instead be sleeping, and I can't for the life of me figure out what it is. Which is why i think it might be hardware.
I will do the deeper cleaning operation as soon as I can get my hands on a pin-like object small enough that's not metal. Everything i have is either slightly too big to reach more than just the surface of the port, or thin enough but metallic.
