samsung a20s bootloop crash - General Questions and Answers

hi
i'am able to go to download mode using volume up+volume down
but it immediately restarts and beeps with nothing shown

have you tried wipe data/factory reset via recovery mode?

first time when the battery had charge recovery screen showed for a second and restarted repeatedly,
i tried to discharge the battery to zero because it couldn't go to download mode,
and then when the battery out of charge when plug it to computer or charger nothing is shown but hearing some beeps similar of the first time, this time i'am able to go download mode but restarting after some seconds

sorry for the necroposting, but did any of you @eng.saad and @cjay da boss manage to solve the problem on a20s? Mine started to boot loop and I can't even get into recovery mode, it restarts almost all the time and all that appears is a screen with the name of Samsung and the cell phone model

ty for reply! I opened the back to get access to the battery, but I couldn't. It has a thin metal plate that doesn't come off, even if you remove all the screws.

[LG P-350] Get stuck on LG logo

Yesterday I run out of battery for 2 hours, when I put some i got stuck on the LG logo, and the touchable keys start to blink.
As normal I tried to log in in Recovery via AmonRa 2.2.1 but it makes me log on Emergency Mode. I tried KDZ Update but when it reebot after flash the new rom I get stuck on the same problem. What can I do?
That's the error that appear to me when I try to update bu KDZ:

Some additional information:
I tried to use the fastboot too, but it dont work as well...
Do not appear the message that makes me able to install a recovery for exemple. I looked on my ADB Interface driver and it says that it didn't reconize my device.
So... I can't fastboot too..
Is this a hardware problem?

shutdown and press the button combo you use to get into custom recovery for P350 (like in my P500 case, its POWER + VOL DOWN + HOME)
This will hard reset your phone, as after every KDZ flashing, you must hard reset your phone or it will bootloop, as in your case it is
I hope you get it.

[Q] I need help with my OnePlus after double root (i assume)

I did flash the lollipop alpha. Realizing that there's nothing much I can do I decided to go back for CM11S. During the process I re root the phone try to flash the CM11S. And after finished flashing the phone won't boot up (even with any combination of buttons). My computer didn't pick up the phone as well. Does this mean that my One+ is bricked? Is there any solution?
Please help
My OnePlus screen never turn on after this happen to me. All the response from the phone was vibrates. Vol up/ down + power, I tried everything, but only vibrate and nothing happen after that.
If there's any help I would appreciate!!!!
Have you tried this? https://forums.oneplus.net/threads/...-solution-to-all-kinds-of-soft-bricks.142870/
Also, when you try to boot into fastboot, it does vibrate, right? Your computer should acknowledge the device is connected if that's the case.

I have the same exact problem. My computer is acknowledged that the phone is being connected, it makes a classic windows sound of connected device into USB. But visual notification is not there as well as there is no new device displayed in the system. This just happens when I try to fastboot (power on + up button).

You should still be able to push to the phone even if nothing is on the screen.
Even if it doesnt pick up the device on the computer or in cmd?

stuck with the warning triangle say an error has occurred while updating the device software. use the emergency recovery function in the smart switch pc software.
Try these steps.
1. Press and hold both volume down + power buttons at the same time until the phone LCD shuts off.
2. Once LCD powers down press and hold volume down + home button + power button to get to download mode.
3. Reflash stock 5.1.1 ROM via odin.
4. If it does no work bring your S6 back to Samsung for warranty repair.

This happened to me yesterday. Just hold the power button for a while and it should go forward. You might have to make sure you're not plugged into the charger also, but I can't remember if I did or not.
Doesn't work for me. Tried holding the power for a loooong time, does nothing. Tried vol down + power, does nothing. Tried vol up + power, device restarts, but comes back to that error screen. Mine is IN2019 (Verizon).

To remove your device from the boot sequence error
Spoiler: OnePlus Fastboot Mode Using Physical Buttons
Press and hold the Volume Up’, ‘Volume Down’, and ‘Power’ keys together until the device vibrates > release buttons > enter Fastboot Mode

More details would be a minimum.
so my firmware is 11.0.3 stable indonesia (did not update it at all since i first used the phone). I was charging the phone, unplugged it at 80%, then the poco launcher became unresponsive, i couldn't operate the screen so i had it restart by pressing power button. after reboot it just won't go past the 5G logo. i
