Help!!! Combination File for S9+ SM-G695 -- FRP Google Accnt Lockout - Samsung Galaxy S9+ Questions & Answers

Please help me to resolve the FRP for my google account on my Samsung S9+ which I've encountered.
I have A Canadian S9+ model SM-G965W and downloaded the following Combination Files including the the American version which i read on a forum would work for the Canadian version so that I can get into the phone to gain develop access, factor reset and flash with original ROM. I have downloaded the following combination files: Combination_FAC_FA80_G965U1QU1ARBA.ZIP, Combination file G965WVLU1ARBG_G965WOYV1ARBG_GLW and file Combination_OXM_FA80_G965FXXU1ARB7_OXMFAC_CL13084894_QB17151834_REV01_user...rar which I downloaded off the web. Just to note I used 7 Zip software to unpack these zip files into .tar format for odin3. The firmware/bootloader i downloaded from Sammobile was G965WVLU1ARBG. When I try to flash any of these Combination files above with ODIN3 V3.13.1 it gives an error code after a few minutes of doing nothing. I have downloaded the samsung driver for mobile phones.
The error code in Odin3 is "Can't open the serior(COM) port. Please help me why i can't flash the combination to access my phone? What is going on with this error is it because I'm using the wrong combination file for S9+ Canadian verison?
Please help me resolve my problems to fix my phone so i can gain access to it. I'm new to the community and the whole process of flashing/routing phones.
thanks

Make sure you installed the samsung USB driver and have the phone in download mode.
Also USB debugging needs to be enabled. If you can enable developer options under settings and toggle USB debugging there. Otherwise unless you have somehow or another fudged it good just boot the phone normally and obtain the Google account information to access the phone. Then when you gain access be sure to factory reset it normally as to remove that lock.
There are videos and etc. on YouTube which discuss using some sort of automation application to enable USB debugging... I dont kmow if that is safe or if it works. Personally I would just get the person who had the Google account to disable the FRP lock, factory reset it.
Otherwise there are 3rd party pay for services that help with the FRP lock.

[J5108/J7108][GUIDE]how to root the Galaxy J5/J7 2016 models J5108/J7108

Hi Evryone.
Because I didn't found CWM or TWRP Recovery or any root method for the galaxy J5 J5108 and the J7 J7108, I made a pre-rooted firmwares for those models.
This firmware base on the hong kong firmware which include the Google apps, this a full firmware exactly like the original, except the root.
After flash you will see the SuperSU app in the app drawer.
Also, this firmware contains the bootloader from the china firmware which doesn't have frp lock.
The root include the binary files in the system, and a pathed boot. (from Android 6.0 or samsung 5.1.1 pathing the boot is necessary for the root work properly)
Flashing this firmware will not wipe data automaticly. you should not lose anything.
This file will work on any firmware/baseband/csc. you can always flash it like a stock firmware.
J5 - base on - J5108ZHU1APD2.
Android version: 5.1.1
J7 - base on - J7108ZHU1APD1.
Android version: 5.1.1

Installation instructions
Before flashing check the CROM Service status in Download mode, if it locked you will need to unlock the bootloader first with the app attached.
Install samsung usb drivers from here.
Download the self extracting 7z file above and extract it (just double tap) to some folder, you should receive a tar.md5 file.
Open odin 3 (attached in the zip)
Put the tar.md5 file in AP.
Put the device in download mode. (vol down + home + power button, and then click on vol up)
Connect your phone to usb and wait for odin detect the device.
Click start.
After it finish choose reboot system now in recovery.
Enjoy.

Thanks a lot avicohh. This was simple and painless. I now have google services on my mainland China phone. And root too! And like you said - I did not loose anything.
well now i am stuck. I enabled my google account, installed and updated my apps through google play, shutdown and now I can't boot. The message in red on the top of the boot screen is:
"KERNEL IS NOT SEANDROID ENFORCING
Custom Binary blocked by FRP lock."
I also cannot reflash the same HK rooted firmware using Odin
apparently I should have enabled developer options then enabled OEM unlocking before rebooting. But I didn't know that so for now I am bricked
Also apparently, the fix for it is to reflash the original firmware using Odin. I am now downloading the firmware from http://updato.com/firmware-archive-select-model?record=1F170CA05E5611E6B055FA163EE8F90B but it is still another 2-3 hours to complete the download (yes, poor internet connection here.)... So I'll see how that goes...
OK, that didn't work. Now the message on the download mode screen says:
SW REV. Invalid type.
FRP is enabled, not allow download non FRP bootloader binary
Well..
I just recently had the same problem in another device.
I don't think the "Oem unlock" has nothing to do with this. the problem is that when you're adding Google account the frp (factroy reset protection) is automaticly enabled, and then it blocks the pathed boot.
The reason reflash the original firmware didn't work for you is because you tried to flash the china version, that doesn't have google service and also doesn't have frp in the bootloader. (apparently once frp is enabled this kind of operation is not allowed because you are actually trying to remove the frp lock by flashing bootloader..)
I think the solution will be to flash the original hong kong firmware with the frp bootloader and original boot. (or just the original boot)
http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B
Then, try to enable the "Oem unlock" option and finally flash the rooted firmware again.
maybe it will work, I'm not sure about it but I would like to know.
If this won't work, I'll try to combine the rooted hong kong firmware with the non-frp bootloader from the china firmware.
Thanks so much for replying avicohh

This makes sense. I was actually suspecting this and was considering trying the 6.01 HK version since that is the only one I could find: http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B
Now that you've posted a link to your original 5.1 HK firmware I'll try what you suggest. I'll wait to get home before I start the download.
But I still wonder if the 6.01 would work on my phone?
It's a mistake.
This link above is 5.1.1, not 6.0.1.
There is no 6.0.1 fro this model for now.
yes, I see, the website says its 6.01, but its actually 5.1.1. How do I know? BECAUSE IT WORKED!!! It took 7 hours to download but when I got up this morning it was done, I flashed and it worked!!!
I'm going to read up some more on this FRP business before flashing the rooted version again. My old phone (very old) had no such thing. I'd never heard of it till this unpleasant way of learning about it.

Hi guys.
Thanks for your replies.
I've just checked it now on another device.
As it turn out after a several tests, this "custom binary blocked by frp lock" problem occurs only if the oem unlock option is disabled.
Here is what I did, step by step:
First, I enabled the oem unlock option and then I added Google account - nothing happened. frp lock in Download mode is still off and everything working fine.
I removed the google account, turned off the oem unlock option and finally added the google account again - frp lock in download mode immediately switch to on, and when I tried to restart, the device has stuck on the boot. (custom binary..)
I flashed stock firmware (from the link above), the device now bootup normally but the frp lock in download mode is still on. (I didn't remove the google account yet)
Final check - I enabled the oem unlock again, and the frp lock in download mode switch to off.
So..
I can safely say that all you need to do is just enable oem unlock in developer options, and then flash the rooted firmware.
Anyway, to be even more sure, I made a new firmware with the china bootloader, frp now is not even exist in download mode.
You can download the new firmware from here

Hey, How do I enable OEM unlock when I can't even boot my device. it simply refuses to boot.
Hi
First flash the original HK firmware from here. the device should boot up normally.
http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B
Then, enable oem unlock.
Thanks for making the root version of mainland firmware. I'm going to stick with the HK version as I want to have google services. and thanks for testing the oem unlock
I informed myself some more about FRP and OEM unlock and I am now feel safe to use the rooted HK firmware. Except, I came across one note for which I want further clarification before proceeding. The note is from http://www.androidcentral.com/factory-reset-protection-what-you-need-know and it says:
"A couple notes need added here. This doesn't undo Samsung's (or anyone else's) version of Reactivation Lock. If you've enabled data reset protection through your Samsung account, you'll need to turn that off in your Security settings. You can find the switch under the "Find My Mobile" section."
So, I want to be sure I don't have this samsung Reactivation Lock enabled. and that I am in no danger of it auto-enabling. I believe I am safe but I would like to know if anyone has more clear information.
What I do know is before I flashed to HK ROM, when I went into download mode, there displayed a setting:
"REACTIVATION LOCK: OFF"
now, using the HK ROM, it is gone, but in that exact same location is the setting:
"FRP LOCK: OFF"
I think, that means the mainland version of the FRP lock (Samsung Reactivation Lock), is now replaced with the google FRP lock and as I don't have to worry about the samsung reactivation lock anymore. Is that so?
even so, as the article says, I look in "Settings" >> "Lock screen and security" >> "Find my mobile" >> log into Samsung Account when prompted, then it does not display the "Reactivation Lock" option that is shown in at least one guide that I found. I really think this is further proof I don't have to worry about Samsung Reactivation Lock. Can anyone confirm?
Yes I can confirm.
But pay attention that because of the FRP, is not possible to make a pre-rooted firmware for Android 6.0 and above or 5.1.1 Samsung devices, from firmware contains FRP protection like the HK one.
From those android versions (and above), a pre-rooted firmware (or any root method) must include a patched kernel.
Due to the FRP protection, once it turn on, it detect the custom kernel (boot) and not allow the device to boot. (custom binary blocked by FRP lock)
That's the reason I had to replace the HK bootloader which contain FRP protection, with the China bootloader which contain the Samsung reactivation lock. (instead of FRP, because china firmwares doesn't include any google services)
I don't know what the policy of the Samsung reactivation lock, about custom kernels.
And also I don't know if the Samsung reactivation lock turns on automaticly if you are adding Samsung account. (Like the FRP lock)
And one more thing, I beleive most people don't use Samsung account at all.
So after all this,
If it come to decision what to use, the FRP lock or the Samsung one (depends only in the bootloader), I'm pretty sure that in this case (custom boot), the best is to use the Samsung lock, and just dont add Samsung account, or add Samsung account if needed but turn off the Reactivation lock in the Find my mobile settings.
I hope it help you a bit.
Good luck.
btw, If you can check the Samsung lock after root and report here, it would be great.

Oh, at first I thought you meant you rooted the mainland firmware. Now, based on your later post, I believe what you did was to put the mainland bootloader in the rooted HK firmware. Is this the case? If so, that means I can still have google services, and root, and no possibility of FRP issues because its a mainland bootloader. OK, I will try tonight. The Samsung reactivation lock is off by default. Even adding a Samsung account does not turn it on, you have to go into "find my phone" to turn it on. So it should be safe. I will confirm tonight after I download your new firmware.
Yes, this is exactly what i did.
Thanks for testing the samsung account. so it is pretty safe.
yes, this new version with mainland bootloader is good. It seems almost impossible to lock.
Now when I go to download mode, there is no more "FRP LOCK: OFF". in its place is "REACTIVATION LOCK: OFF".
Just for fun I tested by going inter developer options and turned off OEM unlock - then I tried to reboot = success. Enter download mode = still "REACTIVATION LOCK: OFF". Of course I turned it back on again after the test.
and in settings, find my mobile, there is still not a setting for "REACTIVATION LOCK". I have seen an example on the web that this reactivation lock setting should be at the bottom of the options under find my mobile. So, actually now I cannot find any way to turn on the reactivation lock - this is good, its what we want.
Of course to even enter the "find my mobile" section I can do nothing at all (in fact it does not even show me what the options are) untill I give my samsung account credentials. Once I give credentials I can see the options but there is no option to turn on reactivation lock. There is just one thing, maybe, is that in "find my mobile", there a place that says: for more information go to findmymobile.samsung.com. When I go there I have 2 options:
-1) FIND - Find, Lock, Wipe my device
-2) PREPARE - Ready device for Find my Mobile
this "prepare" option I am afraid to try, I am afraid it may be the one to enable reactivation lock. Clearly it is not required to actually find my mobile because I just click the "Find" button and it it finds it for me. So, what would be the use of "prepare"?
At any rate, we know that just creating a samsung account does not activate the lock. I never had a Samsung account before. When I set up this new phone I never did enter developer mode to turn on oem unlock but i did create the samsung account. It was after that I flashed version 1 of avicohh's rooted firmware and when I went into download mode, it said REACTIVATION LOCK: OFF, so creating the Samsung account does not turn it on.

The 101 thousand thread with issue with S7 unable to unlock FRP despite various FLASH

Hi Guys and Gals,
Sorry if this is one of hundreds similar questions regarding the S7 FRP but I believe I have exhausted methods listed on advice posts, this is kinda last resort.
Sadly, my Grandfather recently passed away and he left my mum his S7 G930... my mother then had a friend do a factor reset on the phone but was unable to login into the phone once it was reset as it was asking for previous owner. Yep, they didn't remove his account before doing so, nor did they enable USB debug and I am unsure if OEM lock is disabled or enabled.
Following the advice of the post on here labeled: [GUIDE]All-In-One(stock FW/CSC/ROOT/TWRP recovery/FRP unlock/PIT/unbrick/bootloader)
1. [ODIN FAIL] I tried to flash using CF-Auto-Root (cfar_samsung_sm-g930f_heroltexx_nrd90m.g930fxxu1dqg1_t0) but get the issue custom binary is blocked due to FRP lock.
2. [ODIN PASS but...] Then I followed the advice of downloading the stock firmware G930FXXU1DQG1_G930FOXA1DQG1_BTU and flash just the BL (bootloader) and CP (Modem), sadly... after resetting the device it boots up still asking for the previous owner details which obviously we don't have.
3. [ODIN PASS but...] In the same post it says if the above fails simply FULL STOCK flash which using G930FXXU1DQG1_G930FOXA1DQG1_BTU. I select BL, AP, CP and CSC and ODIN passes without fail but rebooting the default it starts to setup the install and applications, then get the Google previous owner message.
4. [Smart Switch FAIL] Reports USB file transfer is not allowed.
I did read somewhere that you can pair a Bluetooth device after hanging up on emergency services, I'd rather not even attempt this method is unethical.
Is this phone a bin job? or is there anything else I can try? would be nice if my Mum could have a upgrade and something that was his.

[HELP] Locked out of encrypted J5 and unable to flash due to PIN required at startup

Hi
Phone = Samsung J5 (SM-J530F)
We distribute Android phones to members of staff at our company.
As part of security remediation, the phones have been encrypted (using the in-built encryption) and added to an MDM solution.
As part of the MDM solution the phones are as above encrypted and blocked from carrying out factory reset. If you try to do a factory reset it says this is blocked by your MDM.
The issue we are now facing is that we have had a member of staff leave and the phone has run out of battery.
Upon turning on the phone we are presented with the 'require pin at startup' screen.
Unfortunately we do not know the PIN and are therfore unable to power the phone up. As a first point of call I thought I could flash the phone using Odin.
It has come to light that in order to get Odin to work, you need to boot the phone into 'download / Odin mode'. In order to do this, the PIN is required as well.
I have read numerous forums of people suggesting to use the platform tools (ie. fastboot). Upon reading instructions on how to do this, they have said to put the phone into download mode again as per above which requires the PIN again.
Is anyone able to suggest a solution to get into an encrypted Android phone that has require PIN at startup enabled and has factory reset disabled.
Are there any tools that will just completely wipe the storage and re-flash with a firmware without needing to get into the Android system?
The phone in question is a Samsung J5 (SM-J530F)
Thank you in advance

Tab S6: Factory Reset with Stock ROM and still getting "protected by Knox Cloud Service"

Recently purchased a used Galaxy Tab S6. I was warned it had a warning about the bootloader being unlocked. No big deal. The seller couldn't remember his Samsung account credentials so we couldn't factory reset at time of purchase via Settings. No big deal. I went into Download Mode and relocked the bootloader. I went into Recovery Mode and Factory Reset.
Then I ran into "This tablet is protected by Know Cloud Service. To continue setup, connect to a wi-fi or mobile network." I've done that (since I can't skip the step) and get the dreaded "Can't create work profile" error and that's as far as the set up will go.
So I used Odin to flash the latest stock ROM and factory reset again and wiped the cache and I'm still having that problem.
In download mode, I've confirmed that Knox has been tripped.
I've googled like mad and I'm not finding a solution. Can anyone help me out? I'd prefer to stay on Stock ROM so there are no hardware issues (particularly with the SPen) as I'm planning to use this device extensively for note-taking (with OneNote). However, I'm open to custom ROM if that's my best/easiest/simplest route.
Thanks in advance!
If you're able, unlock the bootloader again. When you flashed with Odin, did you use the CSC or HOME_CSC file?

I used CSC. As I understand it, that is the "deeper" reset option.

Correct, that wipes user data.
Unlock the bootloader again, which will wipe the device (again), and see if it's removed the FRP. If not, you should be able to flash TWRP, from which you should be able to flash this to disable the FRP.
I can't access the developer options because I can't get through the setup wizard. So I can't flip the OEM Unlocking so the download mode doesn't give me the option to unlock. I can connect to ADB via the Recovery Mode but Fastboot doesn't see it so I can't do "oem unlock." Are there any other methods to unlock it? My friend Google hasn't found any yet.
Seller was able to login to both his Google and Samsung accounts and remove the device from them. That got me through the 100% Know Enrollment Service before it hung up in the "update" portion again. He was also able to send a message to the tablet from the Samsung account to try and release it further but, of course, since I've wiped it, that message can't get through.
I'm getting desperate. I might have bought a paperweight! Any once else have a suggestion?
Checked with the seller. He bought it from Kijiji as well from the original owner. It's always been a personal device, never an institutional one.
Last night's searching of the internet determined that the device is in "prenormal" status so I'm just going to wait 7 days and reboot. That might be sufficient. Nothing to lose at this point.

Question Sm-t227u mdm lock/rooting help

Hello! So I am on a journey to attempt to root a Samsung tab a7 lite sm-t227u. So I want to be extremely transparent as to my reason for rooting:
I was given this tablet by my father whom got it from a previous job. When he left the job they never asked for it back, a long with a good bit of supplies he had that he got to keep.
So, I have this tablet, I can get into it as it doesn't have a passcode. I have wiped it by factory reset as well. However, it has IBM's MAAS360 installed and after factory reset AND a firmware flash using odin I still cannot get rid of this maas360 mdm. It is not Knox locked. I can activate developer mode and change all those settings, but I cannot download any apps through the app store at all or enable unknown source app install as those are under an IT block. I also do not have the OEM unlock option in dev options. I've tried the whole changing the date and connecting to wifi, with and without sim card but I cannot get this option to show, nor can I unlock the bootload through fastboot.
I have read that most of the new samsung phones do not have a bootloader unlock option, but from what I can tell that is specific to the snapdragon phones, and this tablet is running a mediatek chip.
Now, if I can remove mdm restrictions without rooting that's great, but I have a feeling that is the only way to properly flash this thing to completely remove the mdm.
I have tried the recovery tar that is posted in this forum but I cannot get it to flash, likely because I still don't have an unlocked bootloader
Have any of you all faced something similar or know of a solution? I may call the company the mdm is managed by and just see if they will remove it from their system, but I find it highly unlikely.
SM-T227U is an American model wich doesn't have the OEM unlocking option, you could unlock using unofficial ways but those are not pretty "stable".

Hey man! Still got your tab 7? I also have a SM-T227U and have oem unlocked! After doing the usual stuff, you will want to turn off automatically update in developer settings. After that, go to settings>General management>Date and time and select manual time and date, and set it for exactly 10 days before the day you attempt this. OEM unlock will appear in dev settings!!!
Then turn off device and while holding power up + power down, plug into PC. It will show the pre-download mode screen where it asks if you want to continue. Just follow the on screen instructions to unlock bootloader!
*note that the bootloader unlocking results in an unavoidable factory reset**

Sweet! I will absolutely try this when I get home this afternoon, will report back with results!
But just for clarity. Let's say I start with a freshly wiped tablet. Go through set up and connect to wifi, do I need to add a Google and Samsung account? Then in dev settings, enable USB debugging, also enable wifi debugging? Then change the date. Is there any step I am missing?

Hello! So I am on a journey to attempt to root a Samsung tab a7 lite sm-t227u. So I want to be extremely transparent as to my reason for rooting:
I was given this tablet by my father whom got it from a previous job. When he left the job they never asked for it back, a long with a good bit of supplies he had that he got to keep.
So, I have this tablet, I can get into it as it doesn't have a passcode. I have wiped it by factory reset as well. However, it has IBM's MAAS360 installed and after factory reset AND a firmware flash using odin I still cannot get rid of this maas360 mdm. It is not Knox locked. I can activate developer mode and change all those settings, but I cannot download any apps through the app store at all or enable unknown source app install as those are under an IT block. I also do not have the OEM unlock option in dev options. I've tried the whole changing the date and connecting to wifi, with and without sim card but I cannot get this option to show, nor can I unlock the bootload through fastboot.
I have read that most of the new samsung phones do not have a bootloader unlock option, but from what I can tell that is specific to the snapdragon phones, and this tablet is running a mediatek chip.
Now, if I can remove mdm restrictions without rooting that's great, but I have a feeling that is the only way to properly flash this thing to completely remove the mdm.
I have tried the recovery tar that is posted in this forum but I cannot get it to flash, likely because I still don't have an unlocked bootloader
Have any of you all faced something similar or know of a solution? I may call the company the mdm is managed by and just see if they will remove it from their system, but I find it highly unlikely.

If it has Mediatek chipset then you can use SP flash tool to format the tablet firmware and reflash it.
I would strongly recommend you to backup the NV DATA and NVRAM files before you format the tablet.

You can follow this guide actually! ( https://forum.xda-developers.com/t/...220-t225-install-lsposed-magisk-mods.4406933/) it recommends just skipping the setup junk
I have found that many times, rooting methods work across different models of the same device unless there are some sort of major differences in chipsets or some sort of random change lol
The only thing that doesn't seem to work for our model is section V of the guide which is for the removal of the "bootloader is unlocked" screen at startup. so you will still need to press the power button on that screen to boot up. It's a tiny hassle, but otherwise no big deal in my personal opinion
Make sure to read all the way to the end of the root section (section 4) and especially remember step 7. I retried probably 4 times and even patched the entire AP file of the firmware for use in odin (doing this gives a second warning on Knox screen that it isn't samsung official fw then boots normally into the bootlogo screen) before realizing everything was going fine.. I recommend just using the patched Magisk boot.img first just because I find it unsightly
Just flash the boot.tar in the AP slot. Don't download any of the boot imgs from the guide because they are for the t220's and t225's. I'll link the one I made according to the guide below. It'll save you some time and you won't need to install zarchiver and Magick just to have it factory reset again lol. Just download the latest Magisk apk (26.1) from the official github (https://github.com/topjohnwu/Magisk/releases) and install it when you have completed the 2nd factory reset/the patched boot img install.
