Hello I have an error with a SAMSUNG A53 5G recovery flash:
After a successful “adb reboot bootloader” and “heimdall print-pit” at the attempt to flash the TWRP recovery image " heimdall flash --RECOVERY twrp-3.7.1_12-0-a53x.img --no-reboot " I encounter the error “ ERROR: Failed to receive session end confirmation! “
Here below is the full log of what’s on the screen:
Heimdall v2.1.0

Thanks for the quick reply, No I do not really want the phone online while unlock, but I’ve read that it is advised in 2 post on this forum. But I will try offline first.
Yes this was the screen-copy 7 days ago, the screen-copy from today is the second picture with just the message: No signinfo (RECOVERY) “secure check fail” (RECOVERY)
Ok I will check that, my Desktop is a Linux Debian 13 with:
adb --version
Android Debug Bridge version 1.0.41
Version 34.0.5-debian
Installed as /usr/lib/android-sdk/platform-tools/adb
Running on Linux 6.12.74+deb13+1-amd64 (x86_64)
heimdall version
v2.1.0
and I am following the installation method from the link below but it is maybe not accurate for this phone, I will continue to search for the proper way to install it. I have time to explore, and test various options. And maybe one day the A53 5G will be a supported device. Thanks for your help.
but I missed the point “You are therefore strongly advised to first root your device with Magisk” also I will retry after the root with Magisk. And also a method the flash from SDcard is described on this page.
