I am trying to flash TWRP into my Samsung Galaxy A8 (2018) based on official instructions from: https://forum.xda-developers.com/galaxy-a8-2018/samsung-galaxy-a8-2018-roms-kernels-recoveries--other-development/recovery-twrp-3-2-2-0-galaxy-a8-2018-t3818201
I have followed the instructions carefully and repeated several times. I initially tried things on linux with adb and heimdall, however heimdall was failing to flash, so I returned back to the exact Windows instructions using Odin3 v3.13.1. When I try to flash twrp-3.4.0-0-jackpotlte.img.tar into my Samsung Galaxy A8 (2018) aka SM-A530F, Odin fails consistently with this log:
<ID:0/006> Added!! <ID:0/006> Odin engine v(ID:3.1301).. <ID:0/006> File analysis.. <ID:0/006> Total Binary size: 35 M <ID:0/006> SetupConnection.. <ID:0/006> Initialzation.. <ID:0/006> Get PIT for mapping.. <ID:0/006> Firmware update start.. <ID:0/006> NAND Write Start!! <ID:0/006> SingleDownload. <ID:0/006> recovery.img <ID:0/006> RQT_CLOSE !! <ID:0/006> <ID:0/006> Complete(Write) operation failed. <OSM> All threads completed.

I believe my phone is not RMM locked because I see Developer Options in my settings. I tried the process with OEM unlocking enabled and disabled in my phone Dev Options. No success yet. I googled the issue for a few hours, however people mostly report seeing RQT_CLOSE when phone is RMM locked, which I believe is not my case. Maybe this is related to the recent Android update I installed yesterday.

What does RQT_CLOSE actually mean? Could you please help investigate?
