Black screen - but phone working - Samsung Galaxy Note 9 Questions & Answers

Hello guys, i have a problem with my Note 9. sudnley my phone coudnt turn on the screen. THe sound of unlock screen is working. If i try to hard reset, is working. everything is working, until i unlock my phone. if i unlock my phone, the screen whouldn turn on. only if i have alwasy on display i can switch on.
I had wipe / factory reset. nothing working. if i enter in download mode, still black screen....

I would try connecting your device to a computer with Smartswitch installed and perform a Emergency Recovery on it. If that doesn't work then you need to take it to a Samsung Service Center and let the take a look at it.

I have made with odin, new firmware.. same ****... only when is unlock is making like this. For sure is software glitch. Because when is on screen, workinf all function.

reflash the firmware with the HOME_CSC so it doesnt factory reset. Sounds like a kernel issue to me. In the end, you might need to factory reset anyways, but id avoid it at all costs if you have stuff on your phone you want to keep

When i enter in download mod, all screen is black. I can not see nothing. But if i press volume up, i can see in odin "added". So i flash new firmware, i wipe allready everything. Still same problem.

[Q] cannot start galaxy s after update.zip

Hello
I am in a great panic mode.
I applied this lagfix : forum.xda-developers.com/showpost.php?p=7587405&postcount=417 and since I did it I cannot use my phone.
I am not able to start my phone. It shows me Galaxy S logo, and after that I hear the start up music but nothing on the screen (no animation). Pressing hardkeys does not do anything either.
Above all I cannot even enter my recovery mode. When I press volumedown+poweron button, the screen keeps showing me Galaxy S logo and it does not go any further.
Please help me if you know how to getaround.
Were you rooted when yoou applied update.zip?
Anyway,did you try to shutdown the phone removing battery,and then try entering recovery?
the fix did not mention I had to root my phone, it said it would self install.
Yes I did shut down after removing the battery, and then I am trying to get into recovery using volumedown+poweron button but I am not able to get into it. All I see is Galaxy logo and hear start up music after that with nothing on screen.
OK, I am able to get into recovery mode.. I was trying wrong combinations
Now what should I select I get these options:
1. reboot system now
2. apply sdcard:update.zip (will never do this again)
3. wipe data/factory reset (should I do this)
4. wipe cache partition
yes.. you should do 3.) wipe data. If that doesnt solve your problem, you need to flash firmware agian

Why did you choose to install something not on main page, something obviosuly not very tested and something 2 month old (god knows there are close to ten newer or more tested fixes).
If you can access download mode, than reflash. If not... Well, try the exotic methods (dont know them, as I have working 3 butons)
Hey, for a second I thought it did noy fix my problem as I did not get my animation screen and ony heard music.. But then suddenly it starts up
I think I lost my animation on start up though
I still see that MCR Scripts icon on app loader screen, How could I know if its enabled or disabled?
Thanks a lot guys.. XDA rocks .

I regret doing something like that.. But it was really confusing as there are so many topics on the forum and I was really tempted to solve the lag issue I started facing recently (I installed too many apps).
hey i have the same problem.. my phone goes up into the Samsung logo and hangs there forever, occasionally blinking and making a weird vibration. i've tried factory reset but that doesn't help..
How do i flash firmware again?

[Q] Unroot and Reset without Screen? Pls help

Hi,
ma phone ist broken: the whole screen is just white and has stripes of dead pixels across it:crying:
I would like to reset the whole phone to factory settings, as well as remove all apps and the root access, so I can send it back to LG an try to claim warranty.
I have not found anything on how to unroot the phone.
I can propably reset via the Boot menu (pressing down power button and volume down when booting). But then i still need to know how many times i have to press the down button to select reset, since i can not see anything on the screen.
Any suggestion on how to unroot?
My Phone does have the original LG Rom, however it is rooted an i removed some of the original Apps.
Will they come back to the phone when i do a factory reset?
Or will I have to flash the whole phone again with some stock Rom in these forums?
If i do flash, will these also remove root?
Thanks for any answeres!

No i have the problem, that i am not able to see where to change the connection type when plugged in to the pc.
could you send me a creen shot of the screen, where you choose the connection-type?
I know i can get there by tapping on the notification bar when it is plugged in.
Or do you have an better idea how to resolve this?
Edit:
I have managed to change the connection settings by just tapping on the blind screen.
The LG Support Tool, which I got from the LG Website, tells me that my device is on the newest software, therefore I can not do an upgrade.
How do I solve this.
Secondly, on behalf of the first answere: How do I know if I unlocked the bootloader? I installed CWM, does that mean the bootloader is unlocked?
Thirdly, assume I somehow get to reset the phone and change everything back to factory settings and Apps, how do I know it worked without looking at the screen?
Man this thing is really tricky.

You can force an upgrade using the LGmobile Support Tool. This can be found under options>update recovery in the upper right corner. I suggest you put your phone into s/w update mode before doing this though. To do this, hold the VOLUME DOWN button while plugging in the USB cable and keep holding it until you 'see' the s/w screen (not sure if this is an option for you, haha. Just make sure you hold the V- button for a bunch of seconds). As always, make sure you have all the drivers.

Usually the answer is if you don't know if you onlocked it, you didn't unlock it. But you need to have an unlocked bootloader in order to get CWM, so I guess you do have it unlocked. You can check in the secret menu. I believe the bootloader status is also shown in the upper left corner while in s/w update mode. But since your screen is dead, it's kinda hard to check.

Not sure if that's possible for you.. Perhaps someone else knows a solution for that..
Flashing the kdz will automatically format your system and data partitions
In case you aren't sure from adb shell you can run format system and format data commands or you can use fastboot erase <partition>
Always from adb you can enter the shell and use ls command to list contents of the phon and check if it was wiped

Possible brick after build.prop edit. Verizon LG G2

Hello,
I've been rooted for a few months now and have never had any problems. I wanted to use that Milk Music app from Samsung so I followed the instructions and was able to get it working on my phone and have been for awhile. I recently decided it would be a good idea to change the build.prop file back to its original state, so I copied and pasted it in using Root Browser. (I had made a backup file stored elsewhere). Once I did that I rebooted my phone for the changes to take effect. After I did that I cannot get my phone to turn back on. It displays the LG animated logo screen and then goes completely black. The light on top of the phone radiates blue/green. I've read through several forums about this issue and have tried everything in order to get it to work and for some reason, using my computer and ADB always gives me an error: device not found. I have installed the drivers and everything. Anyone else run in to this problem before? I would really appreciate it.
If you are on stock rom, just rooted. I would think you should be able to factory reset through stock recovery.
Confirm the process but i think you power completely off. Then hold volume down and power at the same time when you see the lg logo release both buttons then press both buttons and hold them.
Should take you to factory reset.
Not 100% certain but this will probably be your next step if you can't get a computer to see it.
Good luck

The factory data reset didn't really change anything. For some reason I cannot boot into recovery mode either. I can put it in download mode though, but my computer still has a problem recognizing it.

If you can get into dl mode then you should be able to return it to stock which should reset everything. Returning to stock has its own downside but at least you'll be up and running again.

[Q] Problems with my S4 ACTIVE

I have a problem with my Samsung I9295... After a change of the Charge/USB Pin conector, I broke mine, the phone started to fail... I turned on the phone and in 5 min or so of it being turned on the screen turn off, sort of, you are only able to see the battery bar.... The after a while even the keyboard and some apps stop working... I did a Factory Reset via recovery and try to do a Wipe Cache, the Wipe Cache FAILED... The Phone still with the same problem.... So I did flash a new firmware downloaded from Sammobile... Everything good, except for other problems similar to the one I had before... Laggy phone, no way to turn off the phone via the software, and when I turn off the display you can see the samsung logo faded, and no way yo turn it back, I had to turn off the phone and it takes forever to restart, sometimes turning on the phone it get stuck in the lock screen and then it restart alone and get stuck in samsung logo, I have to turn it off and then On and the it works....
I also try to flash a 4.2.2 official firmware and everytime with every firmware I downloaded ODIN gives me a Failed Messages...
Any idea on why its doing this?
Thanks for your help...

Stuck on Welcome screen after factory reset

Hello there,
I've just found my old GT-S5300 from back in the day, and I tried turning it on to eventually use it again.
The issue is that when turning on, I get the usual "Welcome to GT-S5300" screen, and it tells me to "Touch the Android to begin"; when trying to do so, my phone doesn't let me go to the next screen to connect to Google and all the miscellaneous steps that come later. The touch screen does react, I can change the language/type a number in emergency call, the Android flashes when I touch it but it doesn't let me go to the next step.
I have tried factory resetting/wiping cache & data but nothing does it, I keep getting stuck on the same screen.
I even tried flashing a custom ROM and the stock ROM, but it seems my phone can't read the SD card I insert in it, I don't know why (32GB, works on other devices).
I have CWM Recovery installed so whenever I go to Recovery mode I have the CWM Recovery menu which appears.
Before burying it in my closet, my phone was indeed rooted.
Do you have any idea if there is a way to use this phone again? Thank you!
