Samsung Galaxy A8 (A-800I) Stuck on Logo Screen with red Custom Binary blocked by FRP

Hello all!
First of all i want to thank this site (and the people behind it) that makes everything android possible.
I feel privileged to be a member of this forum specially on rough times like what i am facing right now.
I rooted my Galaxy A8-A800i the other day and everything went great. I followed the instructions that i found here. Unfortunately, yesterday i turned off the OEM Unlock on my phone. Now, as the thread title says it. it is stuck on the Logo Screen with the annoying " Custom Binary blocked by FRP Lock ". i read a guide that ashyx made and i felt stupid. I didn't know that turning the OEM Unlock will do that to my Phone.
Right now, I am digging deep on this forums to try and revive my phone that is currently in Brick state.
i am downloading a firmware from sammobile for my phone, the problem i have is... i don't know how to use it. I don't know much about my phone but I do want to learn a lot and i know that this is the right place. I would like to ask assistance on how to use the firmware that I am downloading right now, and also, can i make the Knox Counter go "0" again?
Thanks for everything guys. I highly appreciate everything i've learned here so far.

Thank you!... i downloaded the stock firmware from sammobile. but whenever i extract it there's a rar message saying it is corrupted so i DLed a new one, it has the same result. I haven't tried using it to fix my phone but i will try right now. Ill give an update on how it goes.

Tried flashing the new firmware but Odin can't detect my phone. i have the latest Driver for SAMSUNG and i have the latest Odin. I tried restarting my phone and my computer several times but it still fails. i am really frustrated and our of options right now. Even if Odin detects my phone there's no guarantee that the stock firmware will be installed properly since it always shows corrupt when i extract it from zip

Install the Samsung drivers first, reboot your pc.
Start odin in Admin mode then put your device in download mode, plug in the usb cable. Your device should be detected.
Don't try flashing a corrupt firmware, it will be rejected anyway as it will fail the md5 check.
I suggest you use a different browser to download.

@ashyx hey! thanks for all your help. my internet went offline while i was trying to respond to the other thread. my phone is now fixed with your help. Thank you so much! only took 3 mins for the while Odin flashing to complete

This issue is now FIXED

Grand Prime SM-530AZ (Cricket Variant) Bricked

Hello I was recently trying to flash twrp and I somehow bricked my phone and I've tried some things but I cannot seem to get it unbricked so I'm coming here for help thanks.
Edit: Correction SM-G530AZ
(I tried doing this half asleep)

The problem is that the 530AZ has a locked bootloader so your failing the secure checks. You need to download KIES 3 from samsung and put the device in download mode, connect it to your pc with usb open kies 3 and at the top click tools then firmware upgrade and initialisation. It will pop up and ask you to enter the model name enter SM-G530AZ and click ok, now it will as you for the S/N which is under the battery so have that ready before obviously then press ok and follow the prompts it will reflash the stock firmware. I had same prob. You are getting the error screen telling you that you have flashed unauthorized software correct?

Thanks for helping toxinburn. Could you possibly help me install a few things I fear I might brick my device again.

Just let me know what your trying to do and ill see if i can help

Could we pull up some live chat somewhere?

At work right now im in usa central timezone but ya later

Send a PM when available please.

Is there a way to unlock the bootloader on this varient? I recently rooted my Grand Prime SM-530AZ, got Xposed and the Frameworks installed! Then I got a little overzealous and tried flashing TWRP fr the 530H. That was unsuccessful and I had to restore to factory recovery. I am now back to bein rooted with SuperSU installed and Up to date. I am trying to remember how I got the framework to work on my Grand Prime SM-530AZ. But what I really really want is a custom recovery. And in order to do so I am assuming I need to unlock the bootloader, correct? I (think) I used to have an option in my settings that said something like OEM-Unlock and I had it checked (I believe) but now I can not find this setting anywhere. Toxinburn I know you are a very busy guy and you do a lot for the community and it is greatly appreciated. But I was wondering if there was anyway you would be able to help me out with these few things? I would even donate to you for your time because like I said I am very grateful for you and your help!

I believe xposed wont work since we cant flash TWRP.

Correct. I will follow your instructions and see what happens. Thank you!!

Bricked my Galaxy S7 Edge: Odin stuck at initialization, Odin protocol version error.

Hello everyone, hope all is well.
I was trying to install a factory ROM for my Galaxy S7 Edge and during the process, I believe I went and flashed a wrong ROM file (I think it was Galaxy S6 Edge's).
Anyways, due to that, my phone is completely bricked (softbricked? because I can turn it on?).
The problem I'm having is that when I turn on the device normally, it will show the GALAXY S7 EDGE logo but then it'd go straight into recovery mode.
In the recovery mode, it'd say "dm-verity verification failed.. " , "E: failed to mount /system (Invalid argument)". Then when I press Apply update from ADB/SD Card, it gives an error saying "Update from external storage is disabled".
I am able to get into the download mode also and downloaded correct factory ROM and flashed it but it gives me an error saying "Odin protocol version error" in the phone, and in Odin, it stops at "Initializing..." and the program crashes after 5 minutes or so.
I there anything I can do to unbrick this dude? I've been searching all over the place yesterday and could't find a right solution for me so I decided to write one myself.
Thanks in advance and I'll appreciate any help.

First of all why were you trying to flash a stock Rom? Next its a piece of cake take it to your local warranty store and ask them to flash your stock ROM as long as you didn't try to root it they should fash it for you. I've done it many times. Just tell them you were charging it overnight and had it turned off and when you booted up the next morning it was going crazy.
As I said if you weren't trying to root they should do it for you.

That sounds like a clever idea but if there's any way I could try to do it by myself before I take it to them, I wanted to try.

Well now I couldn't flash any of the firmwares out there that I found. I kept on getting the same error stated above. It is usa at&t model.
Perhaps, is there a custom ROM and/or other steps you'd recommend me to try?
Thanks for your replies though, I appreciate it very much.

I will try what you have suggested. But isn't twrp only install-able when the phone is actually turned on to OS? As far as I've researched, I saw that it needs to have developer mode on.

i am not a dev mate just learn from observation lol but from other devices i have seen them bricked if thats not been allowed in dev options but i am not 100% sure on this one service center is probs you best bet as some one said earlier as am sure if thats not checked nothing can be flashed as that command allows it its like the bootloader is still locked kind of thing

I would take it a service repair center before messing it up anymore, just to be on the safe side, you never know with these things, yeah it might be fixable but if knox isn't voided then you can just have it repaired properly for free.

first of all, i need your firmware, your root method you tried. If you bootloop your phone you must flash the stock firmware through odin .. and then root with a legit way.

i am little bit confused, help me to help you ! Well , now your phone is bootlooped or no? If it is not , what rom do you have? stock one ?
You can try this method as well, because the method you tried needs to flash a custom rom . i do not like that kind of root method . For me first you flash twrp through odin, flash root, better magisk, and then flash your rom .

alright you are gonna need to flash stock rom from sammobile look the link bellow, but first create an account on sammobile . the process will take like 3 hours . after that you flash the stock rom, and boot your phone normally, enable dev option by tapping 7 times on build number on software information, then go to developer options and enable Usb debugging, get your phone on download mode by turning off your phone and pressing the power button, bixby button, and volume up to flash root . i think you know the process . i will be waiting for you reply.
search for your country and csc first. unless if you already have the firmware on you pc.

ok, get the firmware for your phone from sammobile.com but use samfirm or frija to download it, flash the firmware in Odin 9 time. yes, 9 times. try booting between flashes and itll go away by the 9th time. Not even kidding

9 time flashing. No chance. FRP lock is almost there.
Installed is G935FXXS6ESI4
What can i do ? Any Idea = Combination Firmware ?

not anymore. there was a patch that fixed the bug that allowed this to occur. Sammy is always right on our tails. now you need the combination firmware, which you flash in Odin as well then follow it up with the stock firmware from sammobile since the combination FW isnt really bootable (it is, but its weird lol)

I flashed the combination firmware. After that I flashed my stock firmware but now I get stuck on recovery screen. First it says "Erasing" and then the dead Android mascot shows up. Can't boot into system. Any suggestions? FRP Lock is still on and I can't flash TWRP, custom binary is locked by frp.

possible solution
Hi, how are you? I'm sorry for my english, I'm from Brazil and I'm using the ksks translator so with my j5 i used the frp hijacker (just put it on google) there you choose the phone model, put it in download mode, install the program on the computer, choose the model, check remove frp and a hijack it! and ready frp unlocked

tried it on another computer? Ive had that issue with my desktop/laptop(s). I never dug into what caused it to fail on the desktop vs working on a few laptops. Literally everything else works exactly as it should on the desktop so i just let it be an unresolved oddity. Likely not worth the time it would take to resolve. Anywho, try a different computer and/or diff cable. I just ordered an Anker cable from amazon and its thicker and more sturdy than the micro usb cable ive been hanging on to from my old blackberry tour. Cables are stupid cheap online these days, even for the very very good ones. Perhaps worth a shot, but i cant suggest that you spend money on anything. I can say that its what I would do.
