Downgrade bootloader - Samsung Galaxy A8 (2018) Questions & Answers

Hello community,
I have a A8 SM-A530F in boot loop, and I'm not able to flash the ITV no brand firmware with odin:
Code:
<ID:0/006> Odin engine v(ID:3.1401)..
<ID:0/006> File analysis..
<ID:0/006> Total Binary size: 5308 M
<ID:0/006> SetupConnection..
<ID:0/006> Initialzation..
<ID:0/006> Set PIT file..
<ID:0/006> DO NOT TURN OFF TARGET!!
<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> sboot.bin
<ID:0/006> param.bin
<ID:0/006> FAIL!
<ID:0/006>
<ID:0/006> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
On mobile (download mode) I can see:
sw rev. check fail (bootloader) device 9 binary 8
Then also:
AP SWREV: B:9 K:8 S:8
So it seems for some reason, there is boot loader V9 but latest ITV firmware from sammobile is v8.... Really I don't know how the v9 is there (the phone isn't mine). So the question is, is there any way to downgrade bootloader (even with root)??
Thank you
Lucas

upload the latest version of the software then it will start

samsung galaxy s5 ROM update problem

Hello,
I tried to root my phone samsung galaxy s5 model SM-G900F, then I tried to flash twrp.
My phone here stop working and on the screen it's written Firmware upgrade encounter and issue. Please select recovery mode in kies. Try more then 10 times and it fails I search on google they are saying that kies is buggy and it better to do it using odin. I downloaded the stock ROM from here sammobile . com/firmwares/database/SM-G900F/ with region United Arab Emirates.
It fails the log is

<OSM> All threads completed. (succeed 0 / failed 1)
can you please advise me what should I do ?
Edit one:
After read the screen it was saying the the size is wrong and image is wrong. I read in google that I need pit file for my model but couldn't find anyone for XSG.
I forgot to mention that I used an sd card in adaptive mode using adt command. Maybe that reason for pit file thing. Now I am trying to recover it using kies on mac.
but in worst case if it didn't work and I couldn't find pit file that mean the phone will not run again ?
Solution: I downloaded android 5 ROM but not for my region then flash it. The phone worked then I updated the phone using system update in the phone it self

Stuck in Download mode

Dear friends!
I myself use and flash a Xiaomi device, easy peazy. a friend of mine kinda softbricked her S10e Exynos and asked me for help, so I try to fix her issue but I am not succeeding. So I am not the most expierenced with Samsung devices.
She flashed a Lineage rom and corresponding TWRP, OEM is unlocked. Now Download mode opens automatically after bootloader warning. So I thought Odin or heimdall should be a piece of cake. But Odin always ends with failed write process and when I flash a recovery with heimdall I cannot reach recovery mode, it is always D/L mode. Cable is fine, tried every USB port on two Notebooks
Original Firmware is downloaded by SamFirm.
Can anyone give me advise how to go on??
Thanks

How do I root my A8?

Yes I know, its a very basic question but I need some help. I was following this https://www.thecustomdroid.com/root-samsung-galaxy-a8-a8-plus-2018-guide/ guide but Odin didnt flash the phone for some reason (I sadly dont have the logs, sorry). The phone ended up getting in some emergency mode and all I had to do was reflash. I still want to root my A8 but I dont really want to follow their guide anymore.
See the Magisk installation instructions.
Please note that since TWRP is available for this device, you don't necessarily have to patch the AP file in Magisk. Just install TWRP, and flash Magisk in TWRP.

Screenshot of Odin please
I figured it out. I used Heimdall with the command
Code:
heimdall flash --RECOVERY twrp-3.7.0_9-0-jackpotlte.img --no-reboot
