Simple solution to that DONT turn the OEM unlocking OFF

This toggle unlocks the bootloader for use with custom binarys and recoveries such as TWRP toggling the OEM unlocking off will stop any custom recovery from being flashed with odin and will also not allow the custom recovery on it to be booted for security reasons related to the FRP lock

The OEM lock is linked to the FRP lock both are run through the same toggle you would have noticed when you enabled it that a warning message appeared about the device losing all FRP security measures when enabled if you switch this toggle back to off your FRP lock re activates and the custom recovery that is already installed will now be blocked from being used and the system will render it a security issue and will not allow your system to boot,

So again to save you all this trouble in the future DO NOT tuurn off your oem unlock while you have a custom binary installed,

Yes your devices security is gone but this is the cost you pay when you decided you wanted to root your device,

There is an alternative though if you know what your doing enable oem unlock flash TWRP flash your root and what not then when finished if you know how to pull the recovery from stock firmware and make it into a flashable file with odin you can have root and what not and also keep your oem unlock switched to off bu ti strongly suggest do your reaearch if you choose to take this path.

Hope this helps guys

thanks Matty! now that I think about it I might have turned OEM unlock off because some bank app suddenly stopped working and I was trying to guess what went wrong.
[Samsung Galaxy S8+ Questions & Answers] corvasce03:
hi i need your help, i have a samsung galaxy s7 and it's locked by frp (sorry for my english but i'm italian), i try to install official firmware by odin but it say an error sboot.bin fail! (with bt file) and say recovery.img fail! (with ap file), now i understand that my bootloader il blocked by oem block, there is a way to unlock by odin mode or others? i can't have access to recovery or phone.

please help me i'm desperate!
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
You need to flash the correct bootloader version to your device IE check the binary number on the firmware file and compare to what is listed on download mode

File binarys have the letter U? example is

G930FXXU2ARA1 or G930FXXU3ARA1

Take note of the number

Now in download mode on the device

Find AP SWREV B: ? An example is

AP SWREV B:2 K:0 S:0

The 2 signifies it's a bit 2 bootloader so the firmware package needed for this device would be for example G930FXX"U2"ABCD

all you have to do is match them up,

AP SWREV B1 = U1 or S1

AP SWREV B2 = U2 or S2

AP SWREV B3 = U3 or S3

As for the flash error message " custom binary blocked by frp lock" means someone has tampered with the firmware, I'd assume you didnt get it from sammobile ? or it's not made for model number check the backing to your S7 model number is located at the bottom in small writing

Will be G930"F" for example also compare the letter to the binary file to make sure your flashing the correct model,

Also what version of odin3 are you using to flash as 6.0 to 7.0 binaries can be flashed with V3.12 as the binary files don't use .lz4 compression however 8.0 binaries do use .lz4 compression this is a new type of compression so requires Odin3 3.13.1 as this odin3 has the capabilities to read and flash the .lz4 binaries to the device

And I'm not sure if your aware but the factory binaries dont have OEM unlock in them to remove the FRP however there is a way that I know how to do it on this particular model but it will vary the B:? In download mode and to if a combination rom is available for your binary number COLOR="Silver"]

All good mate :), yeah once that OEM unlock is turned back off all security features are re activated that was your problem :) did you manage to fix it yet if not all you gotta do is flash the stock recovery and you shouldn't lose your data
[Samsung Galaxy S8+ Questions & Answers] snooyy:
thanks mate:) yes I got my data back, but re-root it would mean loosing them so I'm running without the root now. good thing is Netflix, prime vedio, bank stuff are all working, bad thing is no titanium:((
[Samsung Galaxy S8+ Questions & Answers] corvasce03:
thanks for answer, in odin mode it say rp swrev b3 k1 s2, where can i find the frmware with my binary number?
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
No worries so you have a bit 3 bootloader what does the model number say also in download mode ?

I'll provide you the link to the correct firmware to download that will be 100% official
[Samsung Galaxy S8+ Questions & Answers] corvasce03:
all it say

odin mode

download speed: Fast

product name: Sm-g930f

current binary: Samsung official

system status: Custom

frp lock: On

secure download: Enabled

warranty void: 1 (0x030c)

rp swrev: B3 k1 s2
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Yep sweet also what region are you in also so I can make sure the firmwares modem is also region appropriate as they all run on different frequencies other than that that's all the info I need my friend product name is model number you have the same model as me I have G930F also give me two seconds and I'll get the link for you for the correct firmware, as for frp lock your very much quite lucky the warranty void is only "warranty void 1 (0×030c)

If it were : 1 (0×500b) youd be royally screwed :p for some reason combination roms will not boot on any Knox tripped S7 with : 1 (0×500b) but will boot on any Knox tripped device with : 1 (0×030c) I know this as I have a variety of S7 as I run a phone repair shop and have tested on tripped devices with Knox tripped as both

---------- Post added at 05:34 PM ---------- Previous post was at 05:27 PM ----------

Not sure what region you are but here the link to the S7 G930F pages just scroll down select your country and the select the first available firmware that appears with a U3 or S3 when you have selected your region,

[Samsung Galaxy S8+ Questions & Answers] corvasce03:
ok thanks i try to download it and update you if it go or not
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Hey mate no it will 100% work just select your country all firmware from sammobile is guaranteed to be 100% official I use them myself, the only thing however is you need to make an account but the good news its 100% free to make an account but then there another little downfall download speeds are a little slow in free subscription but well worth the wait as I guarantee it will work :)
[Samsung Galaxy S8+ Questions & Answers] corvasce03:

[Samsung Galaxy S8+ Questions & Answers] jfoley420:
OK someone please help. I'm having this same issue, except I got a galaxy s6, however when I boot into download mode and plug cable up it recognizes the driver as a modem or sometimes I get it to show up in ports but its named USB serial device, so I'm unable to flash anything through odin. I tried plugging my wife's galaxy s7 up to PC through download mode and her phone doesn't even show up as a USB diagnostic port....I'm seriously stumped on this and having a hell of a time trying to find any info on this :( My dumbass had stay awake checked at the time and when I went to turn it off I must have accidently unchecked the OEM unlock option resulting in.....a good headache lol....thanks for ur time guys.
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
No problem mate glad I could help :)

---------- Post added at 01:56 AM ---------- Previous post was at 01:49 AM ----------

Hey mate i run a phone repair shop it's got nothing to do with the phones it's the computer or drivers

#1 What version of Odin are you using, you should be using the latest I use 3.13.1 as it supports new .lz4 compression for 8.0 oreo firmware,

#2 did you install the latest Samsung drivers.exe because if you didnt the information is not on your computer to read samsungs devices all the information to communicate to the device is stored in these drivers,

If you havent this is your problem, go to Google type in "latest Samsung USB driver.exe download" or check the forums here for it also, download it and simply open the exe and install the drivers,

Reboot and now try, if you still have the same issue what USB cord are you using, try an original Samsung USB cable or decent branded one,

If there error still persists what version of windows are you using,

Thanks
[Samsung Galaxy S8+ Questions & Answers] corvasce03:
Isn't this the problem.

Go ti ordino mode on tour device and say that you see (es.odin mode device name ecc.) Say all!
[Samsung Galaxy S8+ Questions & Answers] jfoley420:
Thank you so much for the fast reply...Im not sure what the problem was but I borrowed my friends laptop and installed the usb drivers on that and then downloaded the odin version you mentioned...I think I was trying with 1.10 ...but thank you and the lord, the phone is fixed!!!!! It was either something wrong with my pc or the odin version I was trying with. Man these phones can get technical with the repairs lol. If it wasint for xda I would never figure this stuff out....then again...if it wasint for xda I proabably wouldnt mess my phone up in the first place ;p haha.....good day to you guys!
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Not a problem at all mate :),

From what you have just described it would have been the Odin version only if USB drivers were installed on both, 1.10 is a very very old version and doesn't support the compression system used to compress the firmware file you were trying to install, it does get very very technical sometimes and I even struggle myself sometimes Haha all part of the experience :) glad it's fixed and enjoy your day to mate.

Thanks

I have rooted my wife's phone about a year ago. Debloated, instaled TWRP, everythings fine.

Today, some problem on the headphone connector make me reset the phone, and now come out on bootloop with this 'nice' :( message. I don't know what happened, OEM probably still on.

F&#$%^&# FRP, Samsung and Google.
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Hey mate,

Yep so you will have turned OEM unlock back to off,

What you need to do is put the phone into download mode,

And check the top left corner & last line of writing is AP SWREV B:? Whats the number,

That is your binary number take note of it will be a number ranging from 1-5,

Go to sammobile.com or look here for a firmware that matches your model and also your binary number as you will need to reflash the phone with new software to correct the bootloop issue and re flash TWRP & root again

Sorry for the late reply i run a phone shop so am quite busy alot of the time

FAP lock ?

Hello Matty 1993.
[Samsung Galaxy S8+ Questions & Answers] digdug23:
S9+ stuck in 'Custom Binary blocked by FRP Lock'

Hi Matty1993 - can you help?

Woke up on Monday to 'Custom Binary blocked by FRP lock'. I have not rooted my phone, and have only had stock OTA updates from Samsung. I have Galaxy S9+ (G965). I suspect an OTA update failed overnight.

I have tried loading various firmware onto the phone with Odin c3.13. I have used Frija to download the firmware. I believe my CSC region is NEE (I am in Norway).

My phone in Odin mode says:

Product Name: SM-G965F

Current binary: Custom

FRP lock ON

OEM lock ON

CCIC MAX77705 hw: 3 main : 30

Warranty Void: 0 (0x0000)

AP SWREV: B: 7 K: 7 S:7

DID = 2009740d8fea0011

Frija has downloaded firmware SM-G965F_1_20191125155454_bahhyu94wc_fac.zip.enc4 which includes

BL_G965FXXS7CSK4

AP_G965FXXS7CSK4

CP_G965FXXS7CSJ3

CSC_OMC_OXM_G965FOXM7CSJ1

I have tried flashing both CSC and HOME_CSC.

Whatever I do, the Custom Binary blocked by FRP Lock keeps appearing.

I also tried booting the phone with VolUp+Bixby+Power but again just gives the Custom binary blocked.

Can you or anyone else here help? Desperate!
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Yeah your ota would of triggered the bootloader to be locked again and if you have twrp installed you wont be able to boot back to it as oem unlock wont be on anymore

Youve got rhe correct bootloader version and whatnot for your device and both are the F european/australian variant so everything looks good from information but if its not flashing via odin and is stating Custom binary blocked by frp lock then one of the images has been tampered and does not contain a samsung signature and hence forth will trigger that error message,

Download your stock firmware from sammobile.com slowish downloads but free and gauranteed to be 100% Full stock firmware files, all you need to do is make an account to download which is free aswell to do,

Just select your country and then your latest version available for download, also make sure you are using the latest version of odin to flash after downloading it especially from S8 versions up with all the updates samsung keeps pushing it is always good to keep it updated,

Anyhow flash only the recovery first then boot to it and allow the ota to finish via the blue android screen once thats complete make a full firmware flash and should be back to normal again for you to sign in see how you go and get back to me with results :) sorry for late reply also

Galaxy S7 SM-G930F File Combination

Hi, my galaxy s7 has been updated by OTA and now continuous bootloop, blue screen and yellow triangle "No Command" and then continuous restart, I downloaded files from sammobile, flash with odin is ok pass no error but unfortunately the phone does not work. I wanted to know if there is a file combination for this new bootloader "AP SWREV B6 K4 S5" thank you very much in advance
[Samsung Galaxy S8+ Questions & Answers] paljamp:
For ZeroXO Hi, thanks for your interest, I tried to write you PM but it is not allowed, unfortunately I think I did more damage, I flashed the latest BTU firmware, now in download mode I see this "AP SWREV B7 K5 S6" do you think you can do something?
[Samsung Galaxy S8+ Questions & Answers] Abdulrehman130:
Hi Matty 1993!

Can you please give me the correct download link of (S7 edge) latest firmware.

It is locked my custom binary.

I also took this phone to customer care centre of Samsung but they said they cant fix it.

I accidentally turned off oem lock:((

Here are details of download mode.

Product name : SM-935F

Current binary : Samsung Official

System status : Custom

FAP LOCK : ON

Secure Download : Enabled

Warranty VOID : 1 (0X0303)

AP SWREV : B:5 K:3 S:4

Another senior member of XDA also tried to help me.

He gave me a Firmware and said that it would 100% repaired your phone but after I flash that firmware my phone problem remained the same.

It stuck on boot logo and says (installing system update) then pop up this error (No command).

Please someone reply :)
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Hey mate sorry working on android pie for mt6580,

Okay so i take it your not to tech savvy then,

Good for posting the info up ill find your correct firmware from sammobile.com and post the link here for you to download

You can never be to sure if the images have been tampered with or not when gettimg them through other people always best to stick with confirmed stock images as with Samsung for example say it a boot or recovery img is modified then it must be resigned or the device wont boot on unsigned images, protection they call it haha

Samsung wont touch it either as its

Warranty VOID : 1 (0X0303)

They will only repair if is

Warranty VOID : 0 (0X0000)

Anyhow as youve already flashed it the blue android screen is the recovery applying the flash update so thats ok i suppose means flash was ok the no command error with triangle is also normal atter its been applied however it should take you to recovery mode within 20 seconds from showing it so thats a bit odd

Before i fetch the link though have you tried forcing a soft reboot via the hard keys and sending it straight to recovery mode without giving it a chance to try and boot to see if recovery wont load to make a clean wipe of security partitions etc etc ?

If not with it on logo hold both power and volume down buttons together with the home key all at once as soon as you see the screen go black switch the hard key combo to volume up, power and home key, let me know how that goes first if you can get into recovery make a factory reset then reboot else ill get the link for proper genuine software for you as mentioned

Oh your info you posted on your device statee also

your device is the Samsung G935F European Exynos 8890 variant as its F model a couple of other variants use Exynos8890 aswell but alot of them use Snapdragons which are Qualcomm based processing units these are generally USA based G935T/U/S variant frok what i remember variants such as G935P and V use the 8890 dont quote me on that though havent worked on samsung in a while now so could be other way round but anyway yeah your variant is the euro model F variant

And your running a version 5 secure bootloader and looks like youve at some stage had a version 4 factory service binary on it as its showing S:4 (eg; S=service : 4=binary) K: is of no importance to getting it to boot again so i wont go into detail about that but you may want to write your model number and bootloader versions etc down for future references :)

Hi Matty1993,

I have problem with my Galaxy A40 (SM-A405FN) from Polish distribution T-Mobile.

I stuck on first logo Samsung Galaxy A40. I can off my phone only pluging usb cable and push power key+volume down. I've tried many ROMs from sammobile and different sites from Polish but still stuck on this screen.

In my download mode screen is:

PRODUCT NAME: SM-A405FN

CURRENT BINARY: Samsung Official

FRP LOCK: ON

OEM LOCK: ON(L)

Secure Download: Enabled

Carrier_ID: TPL

WARRANTY VOID:0 (0x0000)

RP SWREV B:3 K:3 S:3

Lately I uploaded version "U3".

Generally the update is successful in Odin, but after that phone is restarting and appears blue screen with android icon and says "Installing system update" but disappears in two second (no progress bar). This is end, still start's with first logo samsung galaxy A40.

Can you help me please ? What else can I do ?

Lukas
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Generally it should stay on the blue screen for a while then come up with an error screen then boot to recovery mode after or reboot as per normal,

Everything looks good from the info you listed,

Did you use known OFFICIAL samsung firmware or are you not sure if its genuine, that may be a reason if its been edited is some way the signatures will be diff,

Other than that if its still not booting id say maybe the eMMC has died on it, wouldnt be surprised if thats the case happens quite frequently on exynos especially, which it looks like you have from the info from download mode.

Hopefully thats not the case
[Samsung Galaxy S8+ Questions & Answers] Lukas345:
I thought the sammobile.pl is official SAMSUNG site. I downloaded software from this site. Maybe I'm wrong ?

Today I'll try upload another firmware using SamFirm_v0.5.0 and the name of the files is "SM-A405FN_A405FNXXS3ATB1_Pie(Android 9)_TPL_Factory Rom (5 File)_20200228"

Do you thing is this firware is no edited ?

EDIT:

I uploaded this firmware but unfortunately have the same situation. How can I chceck my eMMC is still live or died ?
[Samsung Galaxy S8+ Questions & Answers] Matty1993:
Hmmm strange very strange that should be downloading official software from what you provided so thats not the problem, id say maybe somethings corrupt somewhere regarding /boot or dm-verity which is tied to /persistent security features in some ways.

The way i could always tell if a samsung eMMC is bad was by looking for the known signs of it as i used to run phone repair shop

1. If device has random common reboots even after new soft flash the emmc flash is starting to die or just about to

2. If the device freezes and will not reboot unless when using the hard key combo even sometimes then wont work the flash is already gone,

3. If the device powers off whilst in flash mode or during a flashing process from odin with a battery level of more than 20% the flash is faulty

If you have had any of the above symptoms then that will be your problem,

I did see you were S:3 in download mode which states its had a factory service binary of U3 so im assuming you know what a factory binary is and how it all works yes ?

Flash it back and see if it boots the device if so,

Make a reset from the recovery mode then reboot it and make factory reset from settings to wipe the devices userdata partitions and what not,

Then use odin to send the package and see if it will boot, make sure to use the CSC and not HOME_CSC file also, speaking of odin aswell are you copping any flash errors or anything ? Or does it make a complete PASS in odin ?

Sorry for the late reply forgot to mark the thread so i get comments

Cheers
[Samsung Galaxy S8+ Questions & Answers] Lukas345:
Not exactly know how it works ;)

Should I send the whole package or only CSC file ?

I don't have any errors when I flashing phone. Everything is fine, ending complete PASS with green box.

In friday I had in my hand another same model A40 (new, branding the same network) and I was check software version - It was A405FNXXS2ASI2. I try to uploaded the same S2 and I'll try with it. But now I have S3 version and I think it won't work. I also noticed that in my phone in recovery mode the beam (marker) has blue color, and in the another A40 was green.

EDIT:

I forget wrote but once I used Lacking storage booting. I don't know is this had meaning.
