Black screen after Model logo - Samsung Galaxy A30s Questions & Answers

Hi guys, I hope that somebody can help me I'm experiencing a black screen after the model logo. I think that the mobile still works (I can connect with Smart Switch, the alarms ring, the touch is working).
It has happened after the mobile has freezed and I've forced the shut down. Now I'm able to use the recovery and I've tried to wipe the cache, do a factory reset and flash an original firmware with Odin.
Do you have any other ideas? The mobile has the developer option not enabled and it's not rooted. Thank you

I'd like to try to flash a new kernel. Do you have any ideas how to enable the OEM unlock option? I could use a keyboard to navigate in the menus but I have no other mobile to check the steps.
If it helps, I've changed the screen because it was cracked, I've used it a bit and then the mobile has freezed trying to open an app. I had to force the shut reboot with the screen still working and after it I've started experiencing this problem.

[Q] [GT-i9020T] Upgrade to CM7.1.0 RC1 Failed. Desperately need help

Hello, I went through Rom Manager to upgrade to the latest CM, I opted to clear the dalvik-cache, and clear data but didn't back up (I have other backups). It started going through the process, then the phone seemed to reset as if it was done installing and rebooted, It hung there for a long time (15+minutes), then the screen went blank, no lights/no response. I tried to restart the phone, it now stays at the google screen, so I tried going into recovery to flash a previous back up, IT WONT LET ME, the screen just goes blank and the lights at the bottom go on. When I go into fastboot mode it tells me my phone is locked again! And when I try and access fastboot through my pc it wont even read the device..Please help me..factory reset, I don't care..someone please help, what can I do?
Did you have fastboot working on that PC before? I.e. are you sure you have sdk/drivers correctly installed?

[Q] [i9023] Stuck in desk cradle and landscape mode

Starting this morning, my Nexus S is stuck in landscape mode.
When I fist boot up the phone, it seems to launch directly to the desk cradle mode, but it has never been connected to one.
Everything is landscape even the launcher. I can't use the phone because I can't reach the OK button for the SIM card PIN enter screen.
Factory reset didn't help. The inital setup is portrait, but after that it reverts to landscape.
Any ideas? Might this be a hardware problem?
EDIT: Android 4.0.3
EDIT2: I applied the VQ8PQk_V.zip OTA update manually to my stock 2.3.6 version. After a factory reset, the phone works as normal until the first reboot. The accelerometer is still working, i tested it after a factory reset before rebooting the phone.

Sorry me for waking up this thread from his graveyard after 3 month.
I have an i9023 with the same issue of Tocharius:
my device is stucked in landscape mode and when i try to turn on it I cannot enter PIN code because OK button is outside the screen. The only way I have to make it works is to wipe data partition and everything works fine until first reboot.
In addition to this problem fastboot has stopped recognizing my phone, while ADB still recognise it.
When the issue firstly appears I was under CyanogenMod 9 v6.0 (Kalimocho).
I tried to flash other ROMs, but nothing has changed.
I tried to revert to stock, but nothing has changed.
I tried to open the phone, clean every connector i found, but nothing has changed.
Someone can help me?
I got this problem too. Lately I installed CodeNameAndroid 2.0 http://forum.xda-developers.com/showthread.php?p=25941996#post25941996 and after reboot my phone got stuck in landscape mode. I tried to reflash the rom and everything was fine until a reboot. Wiping data and resetting factory helps until reboot. I flashed another rom http://forum.xda-developers.com/showthread.php?t=1588799 and again the phone was stuck in landscape after reboot. I tried all rotation settings but nothing changes.
I was browsing settings searching for something that could fix it and turned adb debugging off and on and now it is stuck in portrait mode.

[Q] Lock Screen not working on Android 5.0 with Root

Hi,
I'm using an unlocked Nexus 5, and flashed as soon as the factory image was released. I used CF-Autoroot to gain root access.
The problem that I'm having is that the lock screen does not work. This means that when I lock the phone (power button), it just fades to black, but when I hit the button again (either immediately, or after a wait), I go straight to where I was, the lock screen does not activate no matter what I do. I've tried letting it time out, still no luck.
When I restart the phone, it shows the lock screen, but sounds like something is trying to unlock the phone, and the phone then unlocks and doesn't lock again. I've tried disabling all Device Administrators, with no luck. I tried a factory reset and then a re-flash followed by another factory reset, and the problem still persists. I've also tried toggling Smart Lock on and off, still no change.
If I go to the security settings and re-select a Screen Lock mode, then the lock screen shows up again, but after I unlock, it goes away never to return.
This has been extremely frustrating, since Smart Lock was one of the features I was most looking forward to. Does anyone know what could be causing this?
The current Root apps that I use are:
1. SuperSU (obviously) 2.23 BETA
2. BusyBox Free
3. AutomateIt Pro
4. Greenify
5. Power Toggles
6. AdAway
7. Titanium Backup
Another note: After the factory-reset, wipe, flash, factory-reset that I did, I restored all non-system Apps and data with Titanium Backup. Just putting this here in case you guys know of any app that causes this problem.

(Help) note 10 plus bootloop issue....

Hello. my phone was bricked yesterday after a month of installing one ui 3.0, this issue also happened also in one ui 2.0, and a month before.
My phone boots up normally just fine but after i enter my passcode in the lockscreen the android is starting popup opens and after that it just freezes and just boos again and repeats the same thing over and over.
I did booted up into recovery mode and wiped my phone's cache and repair apps, but there was no menu for the factory data reset. i don't have any clue this is an software issue or an hardware, i want to recover my phone with ODIN but i don't have my computer here right now.
so in conclusion the problem with my phone is that i can boot it normally but if i type in my passcode and the android is starting.... appears and it just freezes and boots up again.
and i don't know why it doesn't have the factory data reset menu on the recovery mode.
please help.
