serial console pins discovered for debugging startup phase - Nvidia Shield TV & Shield TV Pro (2019) Questions

I found the RX+TX pins for serial-console on Nvidia Shield TV 2017+2019pro.
Using TTL-Level-UART-to-USB and hterm-application I could already see a lot of log-messages printed out in the starting phase of uboot and android.

Rx work?

Yes, it definitely does!
The regular shield software is not expecting incoming commands.
I am making some research with L4T and I am able to send linux command using this Rx.

I tried it, rx only works with an unlocked bootloader, and when the system boots up, it doesn’t stop on the fly, so this is also possible with a simple adb terminalom

How can I have same debug printings using "simple adb terminal"? Explain more...

look in the usb debug settings at the very bottom

Now it really seems to be gone. It would be great if someone could add a copy.

standard android settings! generic bluetooth audio is working!!! thank you scottsdca!

FRIGGIN CHAMPION GENIUS IDEA of scottsdca
get Settings.apk from here:
http://www.glassxe.com/2013/05/23/s...-from-the-hacking-glass-session-at-google-io/
UPDATE: original article is gone. check archive.org if you want to read it. but you can still get the Settings.apk here
don't bother with the Launcher2, all it does is crash immediately. although if you have a thing for apps that crash immediately, well then there you go. could be it's a year old and maybe we need to try a 4.2 launcher.
like the article mentions, nearly all of the Settings stuff just crashes (plus, some of it I'd be scared to mess with anyway for fear of messing up spamazon settings)
I don't have any 4.2 devices (aside from ~ firetv obvs), but if anyone else does (like standard-ish non-weird device... e.g. generic tablet or phone?) - would you mind pulling settings and launcher apks please? they might be more suitable and less crashy...
I haven't done much but so far I have a bluetooth speaker paired, connected, and WORKING - sound is coming out the BT speaker and not my TV.
even fired up PrimeTV and sound was as normal, only it was the BT speaker.
xbmc? darn right the sound is coming perfectly out of the BT speaker.
now I turned off the BT speaker, and sound is coming out the TV again. seamless as it should be.
turned the speaker back on, and it autoconnected, all fireTV audio is back on the BT speaker again.
no luck with BT keyboard just yet, and have other settings to still mess with...
(also: the spamazon settings are all still there and all still work as before)
slightly more useless info:
it seems like anything that needs a PIN code still doesn't work.
which is hilarious for 2 reasons:
- the PS3/BD remote does not use a PIN. but so far every android device I have, asks for a PIN for it. the workaround app for anything up to android 4.1.x (i.e. bluez) is great. but firetv is 4.2 and that app doesn't work with the new bluedroid.
- my BT speaker that is currently working (BEM Cube), also does not use any PIN. but it is different somehow, in that android understands in this case, and pairs without asking for any PIN.
Settings shows the BEM Cube's profile as media audio, as expected.
if I try to pair my BT keyboard, the firetv BT settings gives me a PIN to type on the kbd. but the firetv pairing dialog sits there waiting forever no matter how many times I type ####+Enter on the kbd.
if I try to pair my phone, both the phone and the firetv pop up a dialog with matching numbers, but after I press OK on both dialogs, nothing happens. (sometimes the phone says incorrect / missing PIN, afterward. but not always)
if I try to pair my Supertooth Disco speaker, the firetv asks me for a PIN. in this case the PIN is most definitely 0000. but after entering that, nothing happens. not even any error message.
so it seems to be a generic passcode issue? I haven't looked at logcat yet...
I really wanted to try the Disco because it has some extra controls on it. the BEM Cube only has Play/Pause - which does work correctly in both xbmc and PrimeTV.
addition: I found my crappy old Arctic P311 headset (audio has 0.5s lag on every single desktop, laptop, console, phone, etc. I ever tried it on, that's how cheap+awful it is.) - it also happens to be PIN-less (in the good way like the BEM, not the bad way like the BD remote. whatever the hell that means.), and it paired right away with firetv. and then connected with no problem. it has a play/pause button, and also ff + rewind buttons. all the buttons worked as expected in PrimeTV and xbmc. whee.
also, the P311 shows up in Settings with both a media audio profile, and a phone audio profile. nice.
///
after a ton of times connecting/disconnecting the Cube (only because it was stupid fun and made me smile for some reason), started to get a few sound artifacts, some out of sync a/v, and eventually no sound at all on BT (but still perfectly normal sound on HDMI). probably also worth a look at logcat. I also wonder if all the messing around with the other BT devices that all failed, caused any instability.
restarting BT seemed to clean up the audio weirdnesses -
the settings app WILL let you turn BT off and on, just be careful lol. it scared the heck out of me the first time.
- turn BT off. BT goes off. settings app crashes. uh oh! wtf am I gonna do?
- run settings app again. toggle BT on. settings app crashes. oh no! am I seriously screwed now?!
- run settings app again. BT button is blue/on! waow! Thank Crom!

'developer options' was the very first thing I tried - sorry, no dice (
it, and most of the other settings items, only crash the app.
the only things that work (or semi-work), are:
bluetooth
sound (changing the ringtones is ok, but trying the volume setting crashes)
display (didn't try any of these)
battery (uh huh)
location services (uh huh)
security (but no way am I touching any of those)
dock (yeah, no...)
date&time (it's right, why mess with it)
about phone (tells us stuff we already know)
I haven't really tried to change anything in any of those (except bluetooth obvs) - nothing terribly useful to change, so, to me, nothing else there worth the risk of breaking anything.
the unknown sources box is usually found under security not developer options, but that may crash too

duh me, ugh. yeah you are totally right.
ok, so it is there on the security subsection if I scroll to the bottom.
but, yep, it crashes back to the main settings page. that's unfortunate.

no worries it was definitely worth a try.
ok.

I just had a really stupid idea.
even worse, it actually works. but not sure it's worth making a separate post about.
1. turn on adb wifi debugging
2. sideload your favorite terminal, e.g.
http://jackpal.github.com/Android-Terminal-Emulator/downloads/Term.apk
3. fire up said terminal
4. adb connect localhost
(LOL!)
5. profit? profit!
$ adb -s localhost:5555 install foobarbaz.apk
$ adb -s localhost:5555 shell
...
not as quick or classy as unknown sources, but you can do it all within the firetv and don't need an extra phone or computer. so... kinda not too bad?
///
edit:
the reason I use "-s localhost:5555" is that in some cases the firetv already had an existing device listed, "emulator-5554". which may have been the result of not disconnecting adb from my laptop, or just the fooling around I was doing running adbd and adb on the same device, or...?
once you are in the terminal app, run "adb devices" first. if it already shows emulator-5554, then you don't need to connect a second time and can just use adb normally. if it does not show any existing device, then you do need to "adb connect localhost" but then in that case you should not need to specify "-s whatever" and also just use adb normally.

sorry brother, no dice I tried 4.1 and 4.2 versions too, but not really surprised it didn't do much

I tried pairing a keyboard and got a PIN dialog on the FireTV, but entering the PIN on the keyboard failed. adb logcat showed that the pairing request had been cancelled immediately after the dialog appeared. Perhaps some Amazon modification to the low-level Bluetooth stuff? Interestingly, despite being 4.2 based, Amazon are still using the BlueZ stack rather than Google's own implementation.

It is my understanding that Android now tries to auto guess the PIN to make pairing simpler. Perhaps the pin on your cube is 0000 or 1234, the standard pins, hence the non need to pin pair it.

Hi,
Every one the settings apk does work and you can check the unknown sources box to allow installation of any apk without sideloading!!
You need the settings.apk and you have to tweak a system app. Cant give out all my secrets but it works I can install apks from any market, drop box or even when downloading from a web browser.
Fire TV is the stuff!!! Hope fire tv 2.0 offers HD audio and 4k compatibility and of course more memory :good:

Hello all,
The market helper does allow for any installation of any Google Play Store app however does not allow installation from "unknown sources".

Might be a weird question but: how do I tell which Shield TV I have?

So, I bought a used-but-like-new Shield TV. I want to root it. I posted a while back asking about wired mouses, but when I finally got around to trying to do the OEM unlock stage, I found that the mouse wasn't working in fastboot mode to allow me to click "continue". So, apparently I need a keyboard too? Or am I just following the wrong set of instructions? My Shield TV came with a remote that has no port for charging, because it has normal replaceable batteries. Do I need a usb keyboard? Was I incorrectly following the 2017 root instruction when I should have been following the 2015 version? I am so thoroughly confused and frustrated, man. I honestly just wish I'd bought a crappy Mi Box at this point.
Which instructions did you follow and sounds like you have the 2017 16gb

I was going by this: https://www.youtube.com/watch?v=gqJCjN9twrU&
But, like I said, when I tried to do "oem unlock" through ADB, I couldn't click continue, even though I had a usb mouse connected to the Shield. So, do I need a keyboard instead??

I believe you have to be in the usb closest to the ethernet port and if that mouse is not working try a different one. The shield can be finicky all usb cords do not work with it

So, thanks for your repeated help, I actually just tried the mouse without starting the root process, and on the home screen I can use it just fine, opening apps and whatnot. So, apparently there's an issue in fastboot mode? Any idea what the issue is? I don't want to spend the money on another mouse if the issue is just that NO mouse will work except on the home screen.

Enable USB Debugging on S7 Edge (SM-G935F)??

Hi,
My brothers phone screen is basically unusable.
When I connect the phone to the PC it recognises it in Windows but the phone contains no folders. At first I assumed it was because his screen was locked so I connected a OTG and keyboard and using commands managed to get his phone "unlocked" to the home screen.
However this didnt fix the issue.
Reading around it seems I may need USB Debugging enabled (if he hasn't already) but due to not being able to use the screen how would I do that?
Do I need a MICRO USB to HDMI & USB adapter to use a mouse and TV output?
Or is there a way I can fix this through windows using ADB?
At this point we are willing to try anything as all we are looking for is some family photos off of it then binning the phone and I don't want to put £100-200 into the screen replacement just to attempt this data recovery.
All help is greatly appreciated,
Cheers
ADB is the door to any Android device. As long as ADB has not been activated on the device - and the related RSA keys got created - you have no chance to pull out data from device, IMO.
Ok,
Well see the fact when I connect it to windows it shows the phone but not the folders inside, and I can only assume there will be a popup on the screen mentioning to ALLOW/DECLINE transfer etc..
If I use the OTG adapter I can plug my keyboard in and use the sequence SPACE, SPACE, BKSPACE, BKSPACE, then my PIN and ENTER and it unlocks to the home screen.
But because I would need the phone connected by both PC and KEYBOARD at the same time is it possible to get a splitter on the OTG adapter and this would hopefully let me press RIGHT and ENTER to accept the message?
If not then can the phone be connected via HDMI to see if any message is infact popping up??

OK, new to this. To get usb debugging on, click system. About phone, Software information, build number. Click that several times. (AT least 10). You will see a message that you are in developer mode. Go back to home screen. Click settings icon. Scroll to bottom you should now see { } Developers optiions. Click that. Find the section for ADB, enable ADB. Once ADB is up and running you should be able to pull the files. The screen for an android is the desktop, mouse, and keyboard. (PC analogy). You need something to see your icons, something to click, and a keyboard. If OTG acts as a mouse, and you can see the basic display, and have an external keyboard. I think you can do this. I am not sure what OTG is .

1. I cant follow that process as the screen is completely destroyed (no display/no touch), thats why I have been blindly using a keyboard to try and find the setting
2. OTG is ON THE GO , its a small adapter that lets you connect USB devices to your phone.
Sorry about that. I think you are stuck. without some visual clues I think you can not put the phone in developer mode. Did you try just a plugin (via usb) into windows and seeing if there is a pictures folder?
It find the phone in Windows, but wont display the folders.
The OTG splitter I purchased to be able to connect it to the PC and KEYBOARD at same time didnt work as it doesnt supply power (should have checked reviews).
Any other solutions? Or is this a new screen for £200 just to get data?
I purchased another OTG splitter that has a OTG/CHARGE switch so this should let me connect it to the PC and KEYBOARD.
Can anyone give me shortcut keys or step by step on how many times I need to press certain buttons to get down to the USB DEBUGGING section please?

Recovering data with no screen?

Hello.
I've got my mother's Samsung A20. And i need to recover data, but the screen doesn't work.
When power button is pressed, display flashes the lock screen (wallpaper, current time and so on). And then it turns black (backlight stays on for 30 seconds, and then turns off). Pressing the button doesn't guarantee flashing the display, sometimes it goes black immediately. Touch screen gives no input as far as i know (can't hear anything when trying to type pin). Problem still occurs during and after reboots.
I managed to connect a mouse and keyboard with USB OTG, and i was able to unlock. But the phone has no MHL support, so i can't get any image through USB. I'd try pressing the power button repeatedly to get some image and inch my way through the interface, but the lockscreen interferes.
The USB port is set to Charging Only mode, so i can't copy files to my computer. USB Debugging is disabled, bootloader is locked.
Does anybody have a clue, how to get image? Some way to get data? Maybe some keyboard shortcuts, so i can disable lockscreen and make my way easier? And maybe disable 20 alarms in the morning?

I like to be helpful so I'll try to give you some suggestions but I hope others pitch in who know far more than I do.
I never use the USB cable anymore to operate my phone from my PC (but my screen isn't broken so your situation will be much harder).
I connect to my phone from Windows over Wi-Fi without USB all the time, and I can unlock my screen from the PC, and I can mount my entire Android device as a drive letter on Windows over Wi-Fi, etc., so "maybe" (just maybe though), you can consider using either a WebDav server on Android to access your files and/or adb to bring up and manipulate activities on Android....

However, I don't know if adb will work for you if you can't turn on USB debugging in the first place... but as of Android 12, adb now works completely over Wi-Fi (see screenshots below) without needing the USB cable to establish the initial connection like it used to be prior to Android 12.

If the screen problem is "just" hardware and not software, and if you can turn on Wireless Debugging, you might be able to display your phone over scrcpy or vysor (both of which use adb over Wi-Fi) as shown in the screenshots below on my phone - which never needs the USB cable connection.
Hope this helps, but you seem to need folks who know more than I do as adb/vysor/scrcpy all work for me because I can set up USB Debugging & Wireless Debugging as shown below.
Note that you might have an FTP server or a WebDav Server on your Android phone, and if you do, you might be able to at least transfer important files since they each can mount your entire Android phone as a drive letter on Windows over Wi-Fi (without needing the USB cable).

A20 can have only Android 9, 10 or 11, but thanks for ideas anyway.
I didn't even know adb can work over WiFi, I'll look into it. Hopefully this version can do it too.

Ooops. My bad. I apologize. You'll need the USB cable in Android 11 for a moment to establish the connection first. Then you can switch over to Wi-Fi after that (or you can stay on USB).

I tried one from Amazon but it only works through apple carplay so it only shows on 2/3 of the display.

Hey, this is kind of a stupid question but.....along similar kinda thought, when I connect my phone via USB to my car, is there a way I could see and change the stock parameters in the sound system to something more like my liking. I use wavelet with my phone and when I plug in with USB in the car to drive even the car is effected. Without the wavelet it doesn't sound the same. I'm wanting to see if I can somehow do that so I don't gotta plug my phone in with wavelet. Cause sometimes wavelet acts funny.

What is your car? Do you mean like a equalizer?

I am using the M-Stick MG-S01 off Amazon.
It don't show the whole screen but most. It's also not the greatest, but it works for the most part. Which one are you using?
I was able to get ADB to recognize this system. However I get the error from android ADB tools "The Secure ADB mode is enabled. Please use the GM Secure ADB Client tool to authenticate first." I am looking for a way around this. Any ideas?
Also note I have firefox and airscreen(airplay mirroring) working in the GM emulator so if only ADB worked we could be having so much fun.

I also have a refresh Silverado and just tried a CarPlay box, how did you get it to go almost full screen? Mine still shows the side scroll menu with the clock and media player
I'm assuming you know how to activate developer mode by going
Touch "Settings"->"About"->"Build number"->then tap the white file name several times and it will count down how many taps it takes to enable it.
Still trying to figure out how to sideload apps if anyone has made any progress.
