[Q] Recovery Mode and Download Mode not working

Hello,
I have Samsung Galaxy S4 Mini (9192) rooted with Kingo. I tried to entered Recovery Mode (Power+VolumeUp+Home), a black screen with Kingo watermark appeared and then phone stuck at a brown screen. Now, If I am trying to enter download mode, Odin doesn't recognise my device (however, usb other functionalities are quite okay, can copy paste, view data on phone). I unrooted the phone but still can not go into recovery mode, neither doest odin recognise phone. I also tried reseting phone from settings, it didn't work. How can I get back stock recovery?
Thanks in advance. Apologies for poor terminology.

lenovo a916 only enters meta mode can't access recovery

I failed flash rom and can't enter system or enter downloading mode, pls help!

I want to my current rom G9650ZHU3ARK1 flash into G9650ZCU3ARK1 , lots of tutorials in the internet said that I don't have to turn off the OEM lock. I think that is because I didn't turn off it. I use odin 1.13.1 and ADB is installed, and after odin started progress, it shows me failed .
Then I have to reboot my phone, but there's a warning "An error has occurred while updating the device software. Use the Emergency recover function in the Smart Switch PC software."
I tried Smart Switch but no device shows in the emergency software recovery option .
And now my phone can't even shutdown, or can't enter downloading mode anymore. or recovery mode ( volume up + bixby + power ) , the only thing that it can do is reboot into error interface.
I don't know how to recover my phone, anyone can help me? please.
hey, same issue here, do u fix it?

Samsung Galaxy Tab 3 recovery mode and boot loop

Hi Guys,
I hope someone can help, I’ve watched countless videos and tutorials and not one has fixed the issue I have with my tablet.
Initially I had a boot loop problem and purchased a new battery. Now when I try to enter recovery mode I don’t see a list of commands. When it does enter a mode it only gives me an option to download a custom OS or to restart (which throws it back into the startup loop). If I select the download option the android icon appears with “Downloading”. But in the top left hand corner it says
Odin Mode
Product Name: GT-P5210
Current Binary: Samsung Official
System Status: Official
The tablet doesn’t appear to be doing anything?
Do I need to connect it to a PC and do something else? In the recovery videos online it shows options to clear cache etc but I cannot access any menus? It only will go into the above download mode?
Please can someone advise me
Thanks
Did you solve this problem?
Downloading just means it's waiting to get anything from Odin.
Has to be connected to a PC of course.

Help needed with Samsung A50

So here's what happened.
Yesterday I got a update, so I downloaded the update and postponed the update thinking I'll update it later. While I was browsing Chrome suddenly my phone rebooted and now its stuck in the Samsung screen.
I tried entering into Recovery Mode by pressing power + volume up but it doesn't seem to work.
I tried download mode but seems my OEM is locked. I believe my developer mode is unlocked since I used to install apps from PC.
Is there anyway to fix it? My warranty is out back in March.
