OEM Locked whilst with custom rom - Samsung Galaxy S9 Questions & Answers

OK I have officially screwed up...
So it was all going smoothly flashing a tweaked custom rom and twrp successfully and then I decided to back to stock...
I accidentally (ok maybe not so accidentally) flipped the OEM unlock switch and now I am locked out of my phone since I still had the custom binary on the phone.
I tried to flash the latest stock firmware for the s9 BTU found from samfirm but odin seemed to have not liked the firmware or something and it gave me an a red message on the odin mode screen.
When I try to flash everything at once I get "REV Failed Check (Bootloader)"
When I try to flash just AP I get "REV Failed Check (Kernel)"
At the moment when I boot up I get the message telling me to use emergency software recovery but Smart Switch does not seem to recognise the device either in the emergency recovery page however it does try to connect on the home page.
I'm not too sure what to do, any help would be nice?
Thank you

You cannot downgrade the bootloader, check which version your phone has in Download mode (BL: xx) and check which version the firmware you are flashing has G960FXXU1BRF8

OK I think I have found the BL version from the line that says...
"RP SWREV B:2 K:2 S:2"
But what firmware has the BL Version 2? They all seem to have a BL version of 1 from what you've said?
If there are no firmware which match this, what do I do? Is my phone redundant?

OK
I saw on another thread that was replied to about the Hong Kong version having been already upgraded to BL 2 so I am going to give flashing that a go and I will report back.

Yea you'll either have to do something like that, or wait for your region firmware to have it's BL updated

Tried it out with a BL2 BTU firmware from SamMobile and the flash went smoothly however now I'm stuck in a bootloop when I'm trying to boot up.
I know this could be anything but I can't get any form of logs as the only mode I have is Odin mode available to me...
The way I flashed it was by doing BL first followed by AP, CP then CSC separately with auto reboot and one other one checked that was instructed by SamMobile. I tried to do them together but I keep getting an error of not being able to read a line.
What should my next step be?
What could be the reason for this bootloop as according to Odin the flash went well?
Thanks in advance

You might need to check "Repartition" in ODIN only, flash all 4 parts at the same time, use CSC and not HOME_CSC
Make sure you are using ODIN 3.13.1

Oh yea forgot the update...
I got it working, I think I unchecked repartition and auto reboot whilst flashing all of them together to get it working
So yea this is now solved

I do not understand what is the difference of the files that I flash with factory oxa the samsung firmware.
I understand that the firmware in samfirmware there is only one file within a zip to put in pda only and oxa factory has 5 it is mentioned in the first post to leave the factory.
or you mean that first flash of a file and then the oxa factory?

Welcome to the forum! Your phone's hardly bricked if you can get to download and recovery modes. Flashing the correct (stock) firmware should get you back to working conditions. What Android version were you on prior to it being stuck and what were you trying to upgrade to?

i747M is for the Canadian and Mexican variants. If you were on stock 4.1.2, you should be able to Odin back to stock 4.1.1 or upgrade to 4.3 via custom recovery. You can go to the thread below to check the correct stock image for your phone based on carrier. Make sure you use the correct image as flashing the wrong version could hard brick your phone. Download to your PC and then flash. If you select the 4.3 version, you would need to flash custom recovery to your phone via Odin, save the file to a (micro) SD card and then flash via custom recovery.

If we are going to flash a stock ROM, we would need to flash the correct version as there is risk of a worse brick if we flash the wrong one. When the phone was working normally, the old network would probably be showing during booting. If you got it from abroad, please check if you can get the information from the previous owner. If there is no way of telling the correct firmware, then you can flash custom recovery to the phone and try flashing a custom ROM via recovery. It's always tidier flashing a custom ROM to a device functioning normally but, unless we can be sure of the correct stock firmware to flash, your options may be limited.

I've seen this particular problem reported several times and it's always been a problem with the pit file. Flashing a complete stock system should fix all partition problems though. If the stock file you are using is an Odin flashable file, you may try using Odin 3.09. Otherwise, I'd suggest you find a recovery flashable image and flash via (custom) recovery.

Completely bricked S6 Edge G925T - any help?

I can't boot up, can't get into recovery. I can only get into download mode. No matter what TWRP I flash, it says "Custom Binary(BOOT) Block By FRP Lock" on the Downloading screen.
I tried flashing stock 5.1.1 odin, 5.1.1 bootloader/modem, etc. Can't get past this to get into recovery or boot the device. Any suggestions??
EDIT: Good news! Flashing the stock 5.1.1 odin image worked . (link: http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841)
It even preserved my data and everything (I guess b/c I was on the leaked 5.1.1). I'll probably just back up some things and start fresh on the stock software, but I'm just glad to have it working.

I was running the G925T (edge) leaked 5.1.1 rom ([5.1.1][ROM][TW][OE6] Blck/TW), which worked well for the month that I used it. I had TWRP from that thread installed as well (I think it was 2.8.6.x). Everything was good at this point.
Where I am now:
When I power the device on, it says:
KERNEL IS NOT SEANDROID ENFORCING
Custom binary blocked by FRP Lock.
When I try to enter Recovery, it says:
RECOVERY IS NOT SEANDROID ENFORCING
Custom binary blocked by FRP Lock.
What I did to get here:
SHORT VERSION - flashed latest modem and bootloader for G925T (edge) via Odin.
LONG VERSION
Last night I attempted to flash (via ODIN) the G925T bootloader, modem, and TWRP for this ROM: http://forum.xda-developers.com/gal...-xtrestolite-pure-edition-1-0-beta-1-t3082467
G92xF(D)/T Galaxy S6 Universal Odexed Pure edition ROM
Based on the latest Samsung Stock G925F XXU2BOFJ Lollipop 5.1.1 firmware (Base build date: 20-JUN-2015)
NOTE: I didn't ever get to flash the ROM because the trouble started when trying to flash the bootloader/modem via ODIN.
- Odexed Pure Edition: Odexed & 100% original/Stock files!
Steps followed:
Do exactly step-by-step the following things:
- Unplug your Phone (IMPORTANT!)
- Turn your Phone completely off (This is IMPORTANT)
- Start your Phone in download mode on this way: Press Vol down + Home + Power buttons till the screen turns on, press Vol Up to continue (Only enter download mode on this way, otherwise it won't work!!)[/B]
- Open Odin 3.10.6 on your PC (Make sure you're using this version of Odin, other versions won't work correctly maybe!)
- Click on the 'BL' button, and load in your BOOTLOADER tar.md5 file for your model
- Click on the 'CP' button, and load in your MODEM tar.md5 file for your model
- DON'T TOUCH ANYTHING ELSE (you can brick your phone if you choose other settings in Odin)
- Now Connect your phone to your computer (DO NOT connect your phone before this step, otherwise it won't work!)
- Click on the Start button
- Wait till it finish flashing.
- Your phone reboots automatically after flashing. <--- device never rebooted because ODIN said Failed instead of Successful.
I then tried to flash TWRP 2.8.7.1 (link below) since maybe that had to be flashed before the bootloader/modem, but it failed too.
Links:
Odin 3.10.6
DOWNLOAD - https://www.androidfilehost.com/?fid=95916177934555153
[G925T] Odin Bootloader/Modem Packages:
5.1.1 Bootloader: G925T-UVU2COF6

5.1.1 Modem: G925T-UVU2COF6
DOWNLOAD - https://www.androidfilehost.com/?fid=24052804347766211
You also have to update your TWRP to the latest version (2.8.7.1 or newer) when flashing this.

Is there a file I can Odin flash to disable FRP Lock? I can't boot up to turn it off.
If not, what are my options from here? Any way to preserve SDCARD or even /Data?
If all else fails, what Odin file should I flash to get back to stock?
EDIT: Regardless of what I try to flash in Odin (recovery, kernel, TWRP, modem), it begins the process but then fails because the phone states "_______ is not SEANDROID enforcing" and states FRP lock is on.

SmartSwitch isn't detecting my phone (although Odin does). What mode should it be in? I can get into Download Mode, but that's about it!
Your biggest problem right now is getting past FRP / factory reset protection, the only way to avoid this would have been to turn on bootloader unlock in "developer options"
OEM unlocking.
The security system is protecting your phone from you.
You need to be able to smartswitch back to stock but since your device status was not official, custom after running odin, root or anything else you may have done with root, smartswitch won't recognize your phone.
Without "OEM unlocking" on, the phone will turn on you.
The purpose of this security is to prevent your lost or stolen phone from been modified in any way and activated with another carrier.
Maybe tmobile has a procedure for returning phone back to normal.

Guys at the store couldn't do anything unfortunately. I guess it's just a brick now?
EDIT: The leaked 5.1.1 didn't have that option in dev options either. I guess running the leaked 5.1.1 is where I screwed up, even though it worked great while actually using it. I didn't have root, but I had TWRP recovery.
Would flashing the stock image work since it's not a custom one? I'm downloading it now from here: http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841
I'm guessing it won't work or else you would have suggested it. If anyone has a suggestion, I'm open to it!
It seems like there must be a way to disable FRP with an Odin flash, but maybe not.

After looking over article I give it a thumbs up, it may work for you.
Thats the problem with leaked updates or firmware, sometimes devs take shortcuts in order to package it for flashing and security stuff gets left out.
The ota 5.1.1, shows the option to turn on unlock bootloader .
Keep us posted, good luck.

Thanks for replying, by the way. I got locked when i am still on 5.0.2 and i flash the bootloader and the modem. It was the modem of 5.1.1 didn't go through.
Will it be flashed through the 5.1.1 firmware, if not, any other options can solve the frp locked? Thanks
You need to flash 5.0.2 stock firmware with Odin, then maybe.
You can't flash anything that's 5.1.1 on your phone.

tried, still failed in odin. I think is may be because my bootloader is actually 5.1.1's.
However, I saw above said flash 5.1.1 odin image ? what is that? Thanks.
solve it by flash 5.1.1 tar via odin as above said. thanks.

Updated Bootloader: Bootloop, cannot access recovery, can access download mode !

After updating my bootloader to NE2 using odin, by phone just keeps and booting up to the Samsung Galaxy logo and restarting. The logo appears for a second or so before restarting. I can access download mode, but receive the following:
ODIN MODE
PRODUCT NAME: GT-N7100
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
KNOX WARRANTY VOID: 1
AP SWREV: A2
RPMB: INVALID RPMB DATA
( the last three lines have appeared, and were not there previously before updating the bootloader). The phone was working fine with stock 4.4.2, before installing the bootloader. I cannot access recovery mode, and have flashed TWRP with odin (reported success in odin), but cannot access the TWRP recovery menu on my phone. I have tried to flash stock 4.4.2 again with odin, I do not receive any errors and receive a success 1 in odin where a blue bar is visible (when flashing) on the screen of my phone. But after the phone restarts, i experience the same bootloop problem. Help would be greatly appreciated.
Open Odin, uncheck everything, flash latest stock ROM from sammobile (https://www.sammobile.com/firmwares/database/GT-N7100/), you'll see the word "reset" in the status window, remove USB cable from the phone, remove battery, replace battery, boot into recovery using volume up+power+home, factory wipe, reboot.

Before proceeding, I'd like to ask:
1 - I have a motherboard that I've obtained from China. Would it be ok for me to flash as you've recommended with this motherboard, taking into account the "RPMB: INVALID RPMB DATA" message that appears in download mode ?
2 - Can I install any of the latest firmwares available on sammobile for my galaxy note 2 ?
3 - Would I be able to install TWRP and custom roms after ?
Thanks
1) The important thing is to match the model # to the firmware. If you try to flash firmware from sammobile and it is not the correct firmware, Odin will stop the flash process. As of right now, this seems to be the safest method to get the phone working.
2) See my response to question 1.
3) Yes, you can install TWRP and custom ROMs either before or after flashing a stock ROM. I recommend getting the phone to work with a stcok ROM before trying custom ROMs.

After flashing the N7100XXUFOC2 firmware with all boxes unchecked in odin, i still receive a bootloop, and the phone is not entering recovery :-/. The messages that appear in download mode have remained unchanged.
It's flashing properly with no error? When you try to enter recovery, what shows on screen? Did you try any other firmware? I see there is PE2 firmware too.

Yes it flashes with no errors. When turning the phone on, the samsung galaxy note 2 logo appears for just under a second, and the phone restarts and repeats until i remove the battery. Nothing happens when I try to enter the recovery menu, the same behaviour is observed (phone restarting constantly after showing SGnote2 logo). I have been reading around, and i suspect (just a guess, not sure) that the "RPMB: INVALID RPMB DATA" message that I observe in download mode may have something to do with this.
You may have to have it fixed at a cell repair shop. They may be able to fix it via jtag cable or maybe with an Octopus box.

Is there anything else that i could try ? I used an app to check the bootloader version when it was working on stock 4.4.2, and it stated that it was at LJ7. After updating the bootloader to NE1, I've experienced this problem. Would it be possible to revert back to the previous bootloader ( and would this help ?). I've flashed custom roms with no problems, beforehand using TWRP.
How did you update the bootloader? Did you update the bootlaoder without updating anything else?

I downloaded the NE1 bootloader from a user here who has a list of bootloaders on his profile (user: Androidwizzard), and flashed it using Odin v3.09 with the default boxes checked. I did not update anything else ( just clicked the "BL" field and selected the bootloader, then flashed).
Are you sure the bootloader was for your phone? I know that updating the bootloader without updating anything else on the Samsung s3 can cause the phone to hard or soft brick.

Yeah. Would it be possible to revert the bootloader back to what it was previously ? Also, is there anything else that you may suggest that i could do ? I'm still not sure what is causing this issue exactly. It seems strange that I can flash all files with no errors using Odin. By flashing a later firmware, is the bootloader automatically updated ? ( if yes, then I'm not sure why the app stated that my bootloader version was at LJ7, given that I've flashed stock 4.4.2 with odin beforehand.)
Do you have a link for the bootloader?
Did the phone work properly before flashing the new NE1 bootloader?
Did you try flashing the latest ROM, regardless of the country from sammobile? Something newer than ne1?

I have not tried flashing the latest rom ( I could try, if that may help). I can not provide the direct link to the bootloader, since i will have to produce 10 posts ( new user here lol ). You can find the bootloader by searching google: [bootloader/modem/rom][tw kitkat][4.4.2][pf1 + pc1 + oe1 + od4 + nl1 +], then going to Androidwizzard second post.
The phone was working great before flashing the NE1 bootloader. As mentioned previously, I've flashed the N7100XXUFOC2 firmware resulting in no change.
Try flashing the latest ROM PF1 ROM as that may help.
I think updating the bootloader without updating other parts of the ROM may have caused the problem but I don't know for sure.
If flashing the latest ROM does not work, try flashing the latest ROM with a pit file. If that still doesn't work, you may have to have it force flashed at a cell shop.

I will give it a go right now. Would you be able to guide me to where I could obtain the appropriate pit file for the phone ? The firmwares with PF1 have (orange) carrier. Would this affect things ?
Is your phone a 16 GB or 32 GB model?
It should not matter at this point because you want to get the phone booted. Once booted, you should be able to change the carrier later.

16 GB model. Alright, I'll try to flash the latest rom.

SM-A720F (A7 2017) Flashing INS firmware over XSG - Odin Error

I have a Samsung A7 2017 (SM-A720F) brought from UAE having latest Oreo update. While I tried to flash an INS version over this Odin detects the phone. But after hitting start it takes some time and gives error like failed. I also tried to root it with CF-AutoRoot file. Those also have the same error. Developer mode, USB debugging and OEM unlock are ON. Trying with windows 10 + Odin 3.13 (latest). Any solution ?
Combination file successfully flashed. But, still not able to flash another country File. Can I proceed with original country file (i.e XSG stock firmware) ?
Please help me

Root with twrp and magisk, cfautoroot is OG in my opinion . Try flashing just CSC_home or whatever it is called in Odin.

I'm able to flash Combination file, original country (XSG) file and also flashes TWRP. But, I can't get access to TWRP after flashing it. Always it replaced by Stock recovery. And apart these 3 files nothing flashes, including CSC file alone...

When you flash twrp, untick auto reboot in odin. Boot straight into twrp without booting system.

It won't help change the csc. But hadesrom oneui has a huge selection of csc's you can select when flashing it.

If I flashed HadesROM OneUI with 'INS' CSC can I able to downgrade it with INS Stock firmware in future ?
Is the binary thing really need to consider while flashing that ?
PS : I looked on HadesROM. It is temptating. But, the real problem is with VoLTE which affects the network badly here... The VoLTE only network is a large mess here... And thanks for your unconditional Help & Support :fingers-crossed:

It should work to change csc with Hades and then flash stock. Just make sure you don't reflash csc then because it could change.
