So, my friend directed me to this site to receive assistance, I'll keep things short and simple. I have a Samsung Galaxy Grand Prime
Model: SM-G530AZ
Bought it from "Cricket Wireless"
So a few months ago, I lost some data (pictures/videos) and I was trying to recover them with software I found online "Kingoroot" so now my phone is rooted, and I'm trying to unroot it so that I can once again receive OTA updates.
I've tried factory resetting but that did not solve my issue, as during boot up, the phone still has some customer lockpad that's unlocked image, and when I click system software update in my settings, I get an error message stating "device was modified in an unauthorized manner"
During the rooting process , /system is mounted RW .
If you boot to download mode , you'll see that your system status is Custom ...
This is why you can't get official update . ?
need urgent help really.
my phone has been rooted and has twrp installed for months now with no issues, all of a sudden my phone rebooted to the samsung logo screen with the mentioned error message. i have no idea how and why this error has occured but my phone wont boot to system. i really dont want flash stock firmware as i havent backed things up, is there a way to fix this issue with out doing a full wipe?
you might have accidentally disable oem unlock. so phone is bricked , and you need to flash stock firmware with odin , no other choices . and as you know knox counter will stay 0x1 , root or no root, once you break knox its permanent as knox is hardware, once you root it break an electronic fuse so once you flash stock firmware I really suggest you to install custom rom and twrp again as many things will be blocked if you stay on stock firmware as your device will stay marked as " rooted "

Yeah I had to do firmware install in the end. It's just crazy though. I very rarely go into dev options, I had noto kernel installed and everything on stock aqh3, rooted with magisk and everything worked great, so annoying as this happened at 3am and I have slow internet connection and took me 2 hours to download the 3.5gb firmware file. Urgh o was on the verge of installing a custom rom too, ah well good job I had a lot of stuff saved in Samsung cloud.

yes hopefully cloud is our new god ^^ yes its annoying I agree but its also a great feeling to begin with a clean phone like new after a reset , and I have also a crappy download speed so yes its a pain to download 4gb , and even better when its corrupted and need to download agin good luck with your device
Hey guys I need help.

Can someone help??
I got the "FRP lock" on my Samsung S8 (Exynos) and tried to flash Stock Oreo but Odin fails and the device shows "KERNEL REV. CHECK FAIL. DEVICE:3 BINARY:2".
This stock Samsung Rom worked earlier today so it should be the right Rom for my phone.
Also tried to flash TWRP recovery via AP in Odin which failed with "RFP lock" message showing on the device..
I tried to add a snapshot here but couldn't.
Anyone please, I'm helpless..

Your issue is trying to flash older firmware than what is on your phone. You will need to download firmware with bootloader ver. 3 or higher ( bl ver no. is 5th number from right of firmware name )
Flashing twrp failed because of locked bootloader.

It's just because of the wrong firmware you're using. Because when you upgraded to Android 7, baseband version was also updated due to which you're unable to downgrade your mobile.
hello,
i managed to get the phone back to get in download mode. stock everything, no root whatsoever. my goal is to root my phone and i have experience doing so but i guess i was just unlucky this time.
i tried searching allover the internet for a fix, searching xda etc.
first off: my device is running oreo 8.0 and it's type is G950FX.
I want to downgrade to 7.0 because FRP lock is on, i did turn on oem lock before starting however i am unable to log in to my old google account connected to my phone.
when i try to flash any bootloader i get SW REV CHECK FAIL DEVICE 2, BINARY 1. i tried almost any trick in the book like downloading 7.0 from sammobile, flashing using odin.
the things i run into when flashing are:
1.can't flash the bootloader, probably because of frp lock.
2. when i don't flash the bootloader for 7.0 i get dm-verity error 0x2.
3. when i only flash 8.0 oreo pda & csc and then flash 7.0 pda on top i do get to boot but i get encryption interrupted error.
4. i am able to boot in 8.0 but can't get past the frp.
i'm out of answers, i really hope anyone can help me out of this situation as i want to use my phone.
Help is much appreciated!
edit: i tried flashing multiple versions of android 7.0 but i keep getting sw rev check fail bootloader device 2 binary 1
i basicly want to do this, a downgrade: https://forums.androidcentral.com/s...s8-plus/878062-how-downgrade-oreo-nougat.html
the problem is i didn't sign out of google or samsung accounts before resetting to factory
You can't. You have a new bootloader v2.
A simple search gives you this answer, if you have u2 and CRED bootloader installed you are stuck. No way to go back anymore.
i'm on u2 and CRED bootloader. i did search for this indeed but i didn't want to give up.
do you think there will be ever be a way to get back into my phone again?
If you have FRP lock good luck. I haven't seen a way yet.
I know it's been 5 months and you've probably either gotten rid of the phone or it's sitting in a dusty bin somewhere, but have you tried Galaxy Reaper? It's a pretty legit FRP bypass tool.
Edit: Scratch that. It's apparently been patched since I last knew it to work. Just wanted to double check, and sure enough..
Samsung S8-SM-G950F custom binary blocked by FRP locked, i saw so many theards about this and i read them, and i still don't know what to do, so my question is if i download firmware with "SamFirm" and then use oddin will i get my phone unlocked from that ? As i had custom rom for year and half and today i got that error for the 1st time , also if the "SamFirm" is not good for that can someone give me link for firmware for my phone as updato and all other sites download soo slow at 15 kb/s and i can't use them it will take 20hours to download that (
Similar situation, I broke my S8 screen, so never got it fixed, and was recently without a laptop, so thought id use the S8 thru Dex, it all worked no probs, however, I used to unlock bootloaders to install custom firmware and os's but didnt think id done it on my S8 as it was still under warranty, so upon looking in the developer options, i saw that OEM Unlock was on, so i switched it off, not remembering rooting the phone, now i get same error it bootloops and says custom binary frp lock. Did u ever get yours sorted? I know my google account to login 2 it if i ever get the official rom back working, but trying odin and smartswitch restore im still stuck, just keeps failing, saying frp lock. Cant even get into recovefry mode to factory reset, didnt thiunk i had TWRP installed on it, but i must have. Anyway, if anyone can pls help me pls contact me here or at dcillusionz at proton dot me. Thanks.
PS - I tried downloading from SamFW and using Odin, but FAILED. Hoping u had some luck?
