Originally I had to follow this https://forum.xda-developers.com/s7-active/how-to/guide-samsung-galaxy-s7-active-g891a-t3755939 tutorial to get back into the phone after not knowing the password of the google account that was previously setup. But whenever the phone turned off for whatever reason it would get stuck in a (unsuccessful) recovery loop. Also, when the phone was on it would tell you to restart to undo security changes or something similar. I was never able to flash the stock firmware because anytime I try to flash anything in Bl it fails with a write error. So I tried flashing many, many different stock firmwares just AP or AP,CP, and CSC but nothing can fix this security error. This actually fixed recovery mode but now the phone cannot boot successfully. Smart Switch doesn't work. There has to be something I can do if I can still boot into download and recovery mode surely?

I have an i747 and after a week of research and trail and error I was able to get back to a factory working phone. I wanted to share my findings so that the next person may get up and running a bit quicker. First off, my phone was never rooted. I was getting it ready to sell and was going to factory reset it when I realized I forgot the system password. So I installed Kies and proceeded to factor rest it there. For whatever reason the reset did not take and after several failed attempts with kies the phone began to boot in ODIN mode. I built a USB jig and was able to get back into download mode but nothing would bring it back to life. Downloading the official rom from sammobile and flashing with ODIN3.07 would fail every time. Emergency recovery in kies also failed. So here was my final approach that worked. Maybe the wrong way to do this, maybe the long way to do it.. IDK.. but it worked for me..
1) get the official Samsung files from kies (google -"does kies store firmware")
2) boot do download mode
3) flash CSC file with auto reboot and F. reset time checked
4) boot do download mode
5) flash PDA file with auto reboot and F. reset time checked
6) boot do download mode
7) flash Modem file with auto reboot and F. reset time checked
* I closed ODIN between each step, might be overkill.
** I did not flash the bootloader file
I have read that it takes a long time the first boot, and I have been waiting 15 minutes at the SAMSUNG screen but it is still pulsing so i think it is still processing. If it is still at this screen in the morning, I will let you all know but this is further than I have been in over a week.
On a side note, when it crashed I took this into AT&T they told me over the past month or so they have seen numerous people with the same issue. All from doing a factor rest in Kies. My phone was out of warranty and they barely looked at it before asking me to upgrade. I took it to BestBuy and they fixed it from booting to ODIN mode but it still locked up on the AT&T logo, so I was back to square one.
Food for thought. How about waiting to see if your instructions actually work on your phone before posting them here for people with similar issues to use. Kind of useless if it doesn't end up working, huh?

Seems a pretty long route to take. If you are on an Odin flashable firmware version (e.g. 4.1.1), you only need to flash one partition - PDA. This updates all partitions to stock including bootloader, modem, recovery, kernel. The newer firmware versions - 4.1.2 & 4.3 are, however, not Odin flashable. Also, if you couldn't do a factory reset from settings because of password issues, you could have booted into recovery mode and done a factory reset there. This wouldn't require a password and would still have the same effect of wiping data and returning to factory settings.
If your phone is stuck at the Samsung screen for 15 minutes, then it's stuck. Reboot into recovery mode and try a reset there. If this doesn't work, then it means you have a soft brick you need to restore your firmware via custom recovery. Your phone is never hard bricked when you can get to download and recovery modes. Flash custom recovery via Odin in download mode. Reboot to custom recovery and flash a clean, complete stock image for 4.3. That's your best option now since you are selling

So like the true repository of knowledge we have here, Larry you are correct.. After about 30 minutes I decided it was really stuck.. So this time I watched the process I described above a bit more closely and as you stated the PDA file is all i needed.. but I had tried several from different sources including the office from sammobile and they always crashed. So what eventually worked for me was after being stuck at the samsung logo...
I booted into recovery mode
wiped the cache
factory reset it
then flashed with the Kies PDA file that I obtained in Kies in emergency recover mode.
This finally worked.
and as stated was a shorter route to take. The PDA that i used had 4.1.1 on it.
Thanks for the clarification in the fact that flashing with the PDA takes care of the bootloader, cache, file system, etc.

excitement over came me.
Still having issues
Ok, keepers of knowledge.. I have a phone that will boot up but I have no baseband version. It shows unknown.. I have tried just flashing the modem file but i still do not get it back.. if I try to flash anything other than the official files from kies, ODIN fails. My phone is now at 4.1.1, build JR003L.I747UCDLK3.
If I try to update via wifi with the software updater, it says I am up to date. If I try to update with Kies, it fails..
I am at a loss...
Please help..
Thanks in advance..
Hi,
Hi I was given an s3 sprint. It doesn't get past the sprint screen, but when plugged in it goes all the way until played with then it'll reboot. It does however go into download and recovery mode which leads me to believe its a software problem. The phone is not rooted/ fully stock. Could someone walk me through rooting, installing custom recovery and ROM via Odin? Also there seems to be no water damage. Per download mode:: binary-samsung official
System satus-official
Qualcomm secure boot enable
Warranty-0
Bootloader ap swaev-2
PS I already tried Odin but failed at aboot mbn. Now upon booting it reads ... firmware upgrade encountered an issue. Please select recovery mode in Kies and try again?
Pleas ask in here instead. Also first get the phone working by either flashing it using kies 2.6, or by using odin and flashing this image. Be sure to unzip it first.
So guys, bought this phone used 3 days ago. The phone was rooted and the fingerprint scanner was not working giving some error. So I decided to get the phone returned back to stock.
I flashed the G925TUVU3DOJ7_G925TTMB3DOJ7_G925TUVU3DOJ7_HOME.tar file via odin 3.10.6. All files were successfully flashed with pass message but now i am stuck on the boot screen at s6 edge logo. I did a factory reset and wiped the cache but no luck.
The recovery shows an error of dm-verity verification failed... as well in the bottom. I can get the phone in download mode. The current binary is samsung official but in system status it still says Custom. I tried flashing G925TUVU2COF6_G925TTMB2COF6_G925TUVU2COF6_HOME.tar but it doesn't let me flash it as I read i cannot downgrade.
I have tried searching at different places but couldn't seem to find any appropriate solution as most of them are for cof6 or cof8 firmware. I would appreciate a lot if someone could guide me step-by-step procedure to get my phone working back.
Note: I think that the phone IMEI was also repaired as the IMEI on back glass and in the system does not match.
I also cannot get any assistance from t-mobile as I live in Pakistan. I could not attach shots as i have less than 10 posts so writing the status:
In download mode:
PRODUCT NAME: SM-G925T
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: OFF
Secure Download: Enabled
KNOX WARRANTY VOID: 1 (0x0301)
AP SWREV: B:3 K:2 S:2
Recovery error at the bottom:
dm-verity verification failed. . .
Need to check DRK first. . .
It sounds like there may be an issue with your IMEI. I think you should try and use Smart Switch on your PC to do an emergency recovery. It will completely wipe the phone and reset everything to how it should be.
Emergency recovery requires the serial number in order to proceed. You can get that by going into Download mode but before you hit Vol Up to continue hit Home instead. It will show IMEI and Serial Number (the bottom number).
Samsung Smart Switch for PC can be downloaded from Here. Install Smart Switch. Start up Smart Switch and click more in upper right corner. If you don't have the Samsung drivers installed you can install them from here. Or if you would like to reinstall them.
After you are done with drivers connect your phone to the PC and click more and click "Emergency software recovery and initialization" (the first option). It should ask for your serial number. enter it and it should start doing it's thing.
Hopefully this works for you and good luck.
Thanks for the fast reply. I flashed it using the smart switch software. The program completed successfully but still the same result. Stuck at boot logo and same dm-verity error in recovery
DM Verity Verification failed

Hello , if you still facing this issue after flash full stock
try to write unikernel v8-002 (remember FRP LOCK = OFF )
It must work ,
i am sure after flash Unikernel is will work
post result if not work
Thanks alot @jayshaa. Finally booted up... Hats off to you man...!! :good:
Sorry to disturb again... Today when I restart the phone, I couldn't pass the boot screen as I gave me the error Custom Binary blocked by FRP Lock. Frp lock turned on automatically and now I am again stuck at the boot screen. I again flashed the stock rom but the frp lock is still on. I couldn't flash the kernal as well because of this lock.
Someone please guide me to turn this frp lock off and get my phone working again.
Need to check DRK first. .
This error means at some point your efs probably was wiped meaning the drk was wiped... unless this is fixed the phone will boot loop everytime you update unless you flash a modified kernel...
So how do I fix that or turn frp lock off?
Anyone???

That can only be turned off via Developer Options in Settings. If you flashed a custom kernel then you cannot turn it off because you will boot loop. You must flash stock kernel. Or just reflash the stock firmware package.
After you get back to stock. get to developer options and turn off the FRP lock. Then you can flash away.
hi all
im experiencing some weird situations on my razer phone.
flash magisk via recovery works how ever if i try to do a factory reset or backup my phone via recovery or even restore from that backup the phone refuses to boot, it gets stuck on the razer screen for about 2 mins before rebooting into download mode.
manually changing the active partition doesn't help and the only way to fix it is to re-flash the stock firmware.
bootloader is unlocked and i have ran the "fastboot unlock-critical" command as well
has anyone had the same or similar issue
Try to follow the root instructions again, making sure you flash stock multiple times in the process like it says to. Otherwise I don't know what happened.
I was using Magisk canary build, on update something went wrong and the phone would just hang indefinitely at load screen. I had the latest firmware from updating just last week, so I unpacked it, flashed a new boot.img, and then tried running a fresh root from magisk. On trying to flash that boot image it still would hang at load screen. I then tried switching to stable build but same problem, at this point it started getting wonkyer and I shoulda stopped 2 steps ago. It hung and wouldnt boot even with fresh boot.img from firmware, so I tried switching active partitions, it said I couldnt do it cause "slot change not allowed in lock state" but then shows me as on b whereas I was on a, and now I cant get out of the bootloader, can only push the images that dont require fastbootd (I can push boot.img and like some of the random small ones, I havent tried too many as I am unsure of correct order, but CANNOT push system or recovery, system says to be in fastbootd, recovery says "flashing non-hlos image is not allowed in lock state") my phone says I am not allowed to unlock flashing, I tried running fastboot update and passing in the full firmware download as the update, but it says it is missing the "android-info.txt". So if anyone has any ideas it would be greatly appreciated.
