I don't have this device and I do understand your question. This is a little challenging to answer and I'll do my best to explain it as simple as possible but, I'll begin with stating that you should STOP in trying to force downgrade the Stock Firmware via Odin or else you can potentially trip Knox that can result in a Soft Bricked, or worse, a Hard Bricked device.
In general, downgrading any Samsung device cannot be done unless you have the bootloader unlocked with a Custom Recovery (ie... TWRP) installed.
The reason is because Samsung places safety measures, like Knox, on devices with locked bootloaders. The Samsung developers have placed these security measures, they feel, can harm your device by downloading (though I don't agree with this personally).
The good news is that there appears to be a few threads (as follows) that can help you out with Unlocking the Bootloader for the A720F. Don't be afraid to ask for some member guidance within one of them if you need to.

Hi,
I am using samsung galaxy S5 SM-G900R7, i am able to root this phone then started trying flashing of custom boot.img contating custom zImage. ODIN is showing successful flashing , but when i am restarting its always going in download mode with error message "couldn't do normal boot" . In download mode there is a line "QUALOCM SECUREBOOT : ENABLE". I doubt this is beacuse of locked bootloader.
I want to know is it really beacuse of locked bootloader?
I downloaded kernel for my phone model from samsung official website mentioned below and built in same way they have given instruction, so i ahve less doubt on custom zImage.
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=900r7
if yes then i have second question is it unlockable or not, i am not getting any unlocking method for samsung galaxy S5. whatever info i am getting regarding unlocking is upto galaxy S3 but not helpful for galaxy S5. PLease help me to come to a final conclusion on flashing custom zImage to phone.

As far as I'm aware most Samsung devices if not all have unlocked bootloaders, as for a soloution I haven't seen anything really but some say you need to re-flash stock then try from scrath or make a backup after reflashing stock and a custom recovery then format and restore to get it working.

Thanks a lot for your reply,
I searched regarding this and i found latest samsungs are coming with KNOX security in which SECUREBOOT is there, which doesn't allow phone to boot with any boot image if chacksum value doesn't match. so i feel even if bootloader is not locked here but same thng KNOX security is doing. Help me if you have any idea how to disable it in samsung galaxy S5. Getting way how to disable in previous series but not finding method how to do for galaxy S5.

Hi,
Yesterday night you posted a link, that link was good but still my requirement is different.Yesterday i was not able to go through whole link you provided to me, today i was reading the whole article. its looks like they are trying to save warrany of phone even after flashing custom ROM. They are deleting bootloader contents of flashing ROM, even i will flash custom ROM with deleted bootloader contents, In phone bootloader will remain same with KNOX SECUREBOOT feature. My target is to flash with KNOX disabled bootloader so it will not stop booting with custom zImage.

Actaully that link was removing KNOX from firmware which you are going to flash not from phone if you have already KNOX is there. That is for if your mobile is not having KNOX and you dont want KNOX when you are going to flash with recent updated firmware so you can delete KNOX contents from firmware and can flash.

Hmm, it appears it not possible due to it having a locked bootloader/KNOX not being removable

I recently rooted my Galaxy S7 T-Mobile Variant (SM-G930T) and I did not trip Knox at all (there was no custom recovery). After a little while, I decided I wanted to unroot my device to have access to Samsung Pay, Updates, etc., and also because and because of an issue with a Xposed Module. To do so, I simply factory reset my device from recovery, thinking everything would go back to normal. However, I noticed that Samsung pay would still not work after the reset, as it still believed it was rooted. I checked my information in Odin/Download mode and saw that Know was still not tripped, and the current binary was still at "Samsung Official". The problem, though, was that the system status was at "Custom" rather than official. My presumed solution to this was to completely reset the phone to the stock firmware. I originally tried to use Samsungs programs, (Smart Switch and Kies) but they didn't work as I kept getting the error saying the model 'SM-G930T' was not supported. I know I can reset the firmware using Odin but I am Hesitant. I don't know if flashing the stock firmware with Odin will trip Knox, and I am also unsure of where to find the latest firmware for my device. To recap, I basically want to return the status to official and also be able to use Samsung Pay/ receive OTA official updates without tripping Knox.

Thank you for this. However, I don not believe this is the most recent firmware and I am also still unsure if Knox will trip as a result from this.

I've figured it out. I downloaded the latest firmware for my device off of sammobile.com then flashed the files using Odin. It did not trip Knox and i was able to use Samsung pay again. If anyone wants to do this or has any questions you can private message me or reply in this thread.
Glad you found you way.

I have spent the last two hours doing web searches to get this answer, and I deeply apologize if my search efforts have just been ineffective. That being said, I am looking for a way to root this device, temporarily, in order to execute a system installation of an application. Afterward, I intend to unroot the device. My goal is to keep Knox intact, if possible (in 2016 it was not), but if a Knox trip is unavoidable, I would prefer to have some way to be able to have fully functional S Health and Samsung Pay.
I saw there was some mention of the latter being possible through an upgrade from Marshmellow, but I didn't completely understand it, and the statement was vague.
Where are we on March 26th of 2017 on this issue?
And again, apologies if I missed a thread on this exact issue.
73 views and no one knows?
Don't believe what you're specifically looking for is possible. The only root I'm aware of is to flash via ODIN an engineering kernel. Doing so I guess you can then unroot, but you're stuck with the engineering kernel, which many complain about (lag, etc). This method won't trip knox, from what I read. Pay won't work. Closest match for root, check: https://forum.xda-developers.com/tm...eres-how-rooted-nougat-s7-edge-g935t-t3567502

I don't have this device but, the following area of the forum is specific to your device.
https://forum.xda-developers.com/galaxy-j5
With that stated...
This is not an easy question to answer because there's a handful of Custom Firmware releases that's specific to your J5 (2015) variant device.
The following is the area where you can locate many of the Custom Firmwares and don't be afraid to ask for some member guidance within the one you choose to install. Just be sure to read that threads OP (OP = Original Post, which means Post #1) first to prevent from asking a question already answered in it.
https://forum.xda-developers.com/galaxy-j5/development
There's other Custom Firmware released in other areas but, that one is, typically, where they all should be for this variant.
I wish you the best of luck!

Nice.
Can you please share the exact method you carried on?
Follow the guide here to install TWRP and disable force encryption: https://forum.xda-developers.com/t/recovery-official-twrp-3-7-for-galaxy-a52-4g-and-a72-4g.4405751/
After that just flash Magisk.
Greetings to the XDA Team and all the other good people,
I want to root my Samsung Galaxy A52 4G, and just wanted to ask where should I start so I do it successfully, without upside-down moments. I already updated my phone to the latest, so now the phone is running Android 13.
I am a beginner in this, I educated myself from some videos online and on the XDA forum and saw that I can make my device more secure with root, I can disable system and apps trackers.
So my first question is, do I need to downgrade to Android 12 so the success rate becomes higher or I can stick with Android 13 and still get success for the end goal?
My second question is if what I wrote above this is a truth.
The third question is, how do I get my device running again if rooting fails?
The forth question is, can I unroot my device if I want it at some moment?
My fifth and last question is, is rooting worthy and needed so I can achieve my goals?
I still think I know nothing and want to expand my knowledge, so I ask people who are masters in this field to help me out with this, so I can become happier.
Thanks for considering my request.

You can do root your phone. But you should not be panic. carefully read instructions and do it with patient without skipping none of the steps.
I'm also not an expert. but i have done rooting of more than 10 phones without failing.
you have to unlock your boot loader before rooting.
I doubt about your statement about device becomes more secure with root. it depends on what you do alter followed by root. yes you can improve privacy.
also your banking apps may stop work after rooting. so you have to apply necessary modules (security fixes) before get them start working again.
if rooting failed provided phone is not hard bricked, you can flash your original firmware to restore the phone. what i always do is keeping all the original firmware ready with me before doing any rooting.
yes. you can unroot by flashing original firmware.
last question is difficult to answer. majority of people use their phones without rooting. if you want to be different, it's up to you.
