Help CAN'T FLASH FIRMWARE! Android keeps rebooting!

[m_kurti]

Hello everyone,

I have a problem with my Samsung Galaxy J4+ (Android 9). I was flashing a firmware with Odin3, when the electricity went out, and the flashing stopped. I got out DOWNLOAD MODE, and it showed me a screen: "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". When the power came back, I reconnected the phone to PC and it started a reboot loop only in this screen.
I tried to enter the DOWNLOAD MODE again by pressing VOLUME UP + DOWN when the phone started. It asked me to continue or cancel, so I thought it worked, but after I continued (VOLUME UP), it rebooted again, in a infinite loop.

I tried to be fast in flashing the firmware, but it stays in DOWNLOAD MODE only for a couple seconds, and there is not enough time for ODIN to finish it.

I really need some help! If someone know any way to solve this, I would be really grateful if you could help me!

Thank you!

Post a picture of the screen. Or let the battery die, plug the phone into the PC via a USB cable and try download mode.

I have the same problem as this guy describe: https://forum.xda-developers.com/ga...y-bootloop-t3996925/post80803883#post80803883

I tried the solution they provides, but they don's seem to work.
