Bootlooping logo and restarting - Samsung Galaxy A50 Questions & Answers

Hi I used adbappcontroll and uninstalled some system apps now I'm enjoying my time looking at Samsung logo
I have usb debugging enabled but it is not set to always remember this device aaaaaaand i don't have bootloader unlocked my phone is not rooted either
my device is sm-a505f/ds and it was updated to the latest software and I'm looking for a way to either a) ideally use the phone normally
or b) backing up as much data as possible
system / mount seems to have no effect and update from adb can only sideload (idk much about last one)

[Q] gnex dying... (usb and nand chip)

Hi...
My Gnex began to reboot randomly after a long rock solid life (always stock rom with ota upgrades + cwm), so I decided was the time to refresh it installing cm11-m5. During adb shell access to cwm I was warned by several buffer io error on /sdcard but was luckily able to pull my existing files and push the cm11 image, and a new cwm (required by cm11) and finally I was able to flash and boot.
Then my intent was to hack a bit with cwm to do an fsck on /sdcard and eventually some check for badblock, mkfs. etc. etc. but the devices is no more recognized in adb (if full booted with usb debug enabled or in cwm). The devices does not charge anymore but... it charges when powered off and it is recognized in fastboot!
I flashed several versions of stock images thinking it was due to the cm/cwm kernel but the problem is still there.
Usb ports and cable on my several linux boxes works fine (as i see another android phone without problems in mtp/adb/fastboot etc.).
Any help will be apreciated.

[Q] lost usb debug

I broke my phone that i had rooted quite a while ago. I had to get a replacement phone. I have enabled usb debugging but, when i attach my phone to the pc the only connection i can get is "connected as a media device". i just want to root so i can make a back up to put on my new phone.
I also should mention that i uninstalled and reinstalled the samsung drivers to no avail
i think this has worked. http://docwiki.embarcadero.com/RADStudio/XE6/en/Enabling_USB_Debugging_on_an_Android_Device
I still get a shield in the notification bar but, seems to be working so far
So you want to access the /data partition correct? If you had an insecure kernel you should be able to use ADB to pull anything you want off of it.

Trying to get TWRP Recovery and ADB USB Detection

Hi. I currently have root access and had attempted TWRP tethered recovery while on a stock ROM. I can get to the part with the open Android and can select Recovery Mode, but that brings up nothing.
A stupid decision to integrate dalvik with ROM had messed up my system that led me to do a factory reset. That sort of works, though Asus Dialer is sporadic now. I'd ideally want Cyanogenmod 12.1 on it, but at the moment, plugging via USB to multiple systems (Linux and Windows 8) only results in charging (USB debugging is enabled). What options do I have in reflashing either stock or Cyanogenmod, and what apps with easily available apks can I get?
Thank you in advance, I hope not to need a used Moto E as a backup.

T807t broken screen- debugging not selected - need firmware info

After having the tmobile variant of this tablet for 3+ years the screen is officially broken.
With adb debug not turned on I can't access info about the tablet.
I need to find out what rom I flashed on this for the replacement I bought - without the use of the screen, with adb debug mode off.
Is it possible to get the rom fw version without adb debug and no screen access?
P. S. The one good thing - if it is good, is that windows is allowing me access to the internal storage. + it's backed up to my Google account.
Why do you need to find out what rom you had? What are you exactly replacing?
Your device supports MHL.

Unable to see device in bootloader mode.

Hi XDA,
I have a problem where I'm able to see the device when turned on, but when I enter the bootloader through ADB, suddenly the device is not seen anymore. Therefore, I cannot continue to install TWRP (and a custom ROM after).
- I think this has to do with the weird USB driver that appears to be installed when entering the bootloader, it is called "Samsung Mobile USB Modem". In the device manager, it is also in the modem category, which is very odd.
- When the tablet is active regularly, the APK Installer tells me that the Device status is OK, which doesn't appear to be the case in the bootloader...
- When I uninstall the Samsung Mobile USB Modem when in the bootloader, it just reinstalls again if I reconnect the tablet to the PC.
What do I need to do to make sure I can also see the device in the bootloader? I really want to get rid of the Samsung ROM
Thanks in advance,
Reinier
