I have my SM-G611F's KG state set to "Prenormal". OEM unlocking is enabled. But how can I bypass or get rid of KG Prenormal without being able to boot to the OS? Because I want to flash TWRP to make progress but KG stops me. I can boot to recovery, but trying to boot to OS, it reboots automatically.
Is your bootloader unlocked? Like you went and got to the bootloader r unlock screen and it made you factory reset? If not, do that. If so, you have to setup your device (only add wifi, do not do anything else), and then go to settings, and enable dev options. The checked that Orem unlocking si enable. Only then can you flash firmware.

I said I cannot boot to the OS. And yes, I do indeed have OEM unlocking enabled but my KG is set to Prenormal and that prevents me from flashing anything that's not official.

Yea, flash stock AND UNLCOK BOOTLOADER. Enabling Oem unlock is not enoug. The setting simply lets you unlock the bootloader. Afterwards, after the reset, connect your device to wifi and enable dev settings to make sure Oem in on and grayed out.

I wouldn't be here if it was just simple enough as flashing stock. I did it many times, with different countries with U3. Doesn't work.

Yes, with various csces. I tried NAND Erase, Re-partition and various other things but it won't boot to the OS no matter what I do. I was able to boot when I had root, the problem is I don't have TWRP so I cannot root.

did you correctly reparation after nand erase?
I think you screwed up so bad you can’t recover. With a locked bl, ur prob screwed.
At this point, you prob need edl and firehose to recover
At this point it is as bad as a hard brick from what I can tell

I think you didn't notice my reply, so I will ask again. What is EDL or Firehose?
You are right, I did not notice. EDL has little documentation, but ti is pretty much a mode where you can fully reflash your device, including bootloader, into a factory state. It ignores your bootloader being locked, because it operates from a higher level. You can flash a stock firehose file through edl (that’s how you operate it(. Samsung usually does not give away their firehose files, so you can do your best unless you want to send it in.

Well I'm having a strange issue.
I've unlocked bootloader then flashed twrp. It didn't work then. When i boot my phone to recovery, a screen appears with a security warning and nothing happens. Then somehow my frp is triggered. Now i can't flash anything and my recovery is messed up . My phone boots normally though.
Is there any way to unlock the FRP? :/
Anyone? ?

In developer options is OEM setting which need be enabled for FRP unlocked. Probably with unlocked bootloader u cant change this option, so need relock bootloader and enable OEM and again unlock bl

I know that brother. I've tried dload method for full firmware restore. Sadly after 5% it shows error . Now I'm left with no options at all.
I already unlocked the bootloader, happens anything if I turn off oem unlock in developer settings or will the bootloader relock?

Turned it off once by accident but turned on again.. Nothing changed
I don't think anything changes unless u relock it via fastboot, which at that point as long as u can boot back into the OS, u can always unlock it again, relocking bootloader will format ur data and u will no long be rooted or have twrp installed
locking your bootloader with root etc installed can cause major problems so before doing that you should flash a stock firmware otherwise you will be locked out
Why would you want to do this? There is no benefit to it if you plan to stay rooted.
Need to find something to do. You bored

Just turning off Developer Options won't relock your bootloader. You can only do that manually in fastboot. But you'll also lose USB debugging, which means adb won't work anymore in case something goes wrong. (But leaving USB debugging on all the time isn't the best idea anyway.)
Hello everyone
I think I did that mistake
I have twrp installed on my phone Samsung SM-G532F . my phone was working just fine but I have locked the oem for no reason .
now when I turn off the device and tried to turn it on it shows { Custom binary blocked by FRP. (boot. img) }
and when I open recovery mode it shows { Custom binary blocked by FRP. (recovery. img) }
the download mode is working and shows that the FRP lock is on .
I tried to flash the stock recovery with odin but since the FRP is locked it failed .
the adb is not working because the device cannot boot , even the battery symbol when I plug my phone with a charger is not displayed and shows the error { Custom binary blocked by FRP. (boot. img) }
any ideas will help a lot .

You cannot boot with a custom recovery and a locked bootloader. As to how to fix this, you need to ask in the Samsung forums. This is for OnePlus 6.
If you have a oneplus look in the forum for msmdownloadtool and follow the steps, you can revive your phone.
If your phone its a samsung, search in samsung forums for a tool to unbrick your phone.

I downloaded and flashed the official firmware with odin and it worked . thanks for the reply
I did this once on my OnePlus X, disabled oem unlocking in developer options. phone and recovery worked fine. I did a backup. Flashed a new rom to test it. The rom had AOSP recovery in the zip, overwriting twrp (opx has separate recovery partition). I flashed gapps affter the rom and the setup wizard was crashing so I could not boot in the home screen. Tried TWRP, its gone. Tried to boot to twrp via fastboot, oem locked. Had to do hard brick reset. Backup and data, gone.
TLDR, you should leave it on, unless you are on stock firmware.
After flash a rom you must flash twrp recovery again, restart in recovery and flash gapps and magisk
First of all you have to flash combination file associated with your device model through ap slot of odin.
Then your phone will turn on and you can access settings through which you can turn on oem unlock.
Then you can install your desired rom into your device

I also accidentally turned off oem in rooted phone , Does my bootloader locked or I can safely reboot
I restored the stock firmware using Odin, but now I see that the bootloader is still unlocked.
When try to lock it again the system says: "If OEM unlock is turned off, your phone will be reset to factory default settings after restart. This will erase all of your data... " etc.
My question is: will the firmware be still in place? I don't mind everything being wiped, because most of it will be restored anyway when I login to Google and Samsung again.

Did you turn on OEM unlock?
Best method these days is to flash TWRP and then flash Magisk.

Yes i turned it on. u mean debug Mode usb?
Not USB debug, under develop options is a setting called 'OEM Unlocking'. You can't make modifications to your boot partition unless that's enabled, which means you can't root without it.

Are you able to communicate with the device using fastboot?
Try flashing the stock images via fastboot
You won't need an unlocked bootloader for this

whatever command i use it says OEM unlock is not allowed.
Just throwing out ideas that you may have already tried. If I understand right you cannot get into recovery which eliminates trying to sideload the stock image. Your bootloader is locked and it will not let you unlock so booting into TWRP is out of the question. Are you just wanting your phone operational again? Have you tried wiping/factory resetting with fastboot commands? i.e. fastboot erase userdata or fastboot format userdata.

error message " Please unlock the device to activate this command"
anyone else can help ?
I would contact Google customer support. Even though my phone was out of warranty and I was not the original buyer (bought in eBay), they were willing to make a one-time exception for an RMA. I didn't use it because my phone is rooted and I was afraid of being charged for any repairs. As long as your phone is stock and unrooted, you have a chance. Just say that you think you have a hardware failure and while you understand that they are in no obligation to help, you would appreciate anything they can do.

Hey what's up.
Having issues and want to start from scratch but the MSM download tool isn't working for me due to driver issues I can't seem to resolve.
I'm unlocked and rooted with a custom kernel but otherwise totally stock.
Would I be able to just fastboot flash the stock boot.img and relock the bootloader for a total data wipe? Would that be enough to start fresh?
Go into magisk. Click uninstall. Click restore images. Your images should have been backup by the app. Reboot and reset from reset option in phone. No need to relock.
Thanks. Is that as good as the MSM tool as data wipes go? Want to get as fresh as I possibly can without MSM...

what is the best way to relock the bootloader from Rooted( Magisk) and unlocked bootloader ? I did fastboot lock last time, I guess it locked successfully but refused to boot. Had to use msm to unbrick. Could you suggest best practice for Locking the bootloader again from rooted stock ?

You can't lock the bootloader while rooted. Your patched boot fails startup checks. The only phone i remember that you could root and relock was the oneplus one. There was a software hack to do a soft bootloader lock/unlock without wiping the data.
To expand on that, if you modified any locked partitions and try to relock the bootloader, you'll essentially soft brick. The only thing you can modify is I believe is userdata. If you are unsure, why take the chance, especially since your MSM isn't working.
Just do a factory reset from recovery lol or use fastboot
