Bootlooping with FRP - T-Mobile Samsung Galaxy S7 Questions & Answers

My now ex girlfriend returned me the phone I bought her and had FRP enabled since she reset it with hardware keys. I tried a few things, and now it is bootlooping, so the normal FRP bypass options I'm aware of won't work. However, I still have access to Download Mode and the Stock Recovery. Is there anything I can do to get this thing back to it's bootable state, even with FRP enabled?

I have the same situation, have you ever tried this method?

S7 stuck with EFS lock and FRP lock

Hi Guys,
My relative has a stock Australian S7 SM-G930F which has an issue trying to boot, it was running standard optus firmware and just stopped working one day, stuck at samsung screen.
So I tried to perform a factory reset from recovery and still same issue it cannot access the EFS partition.
So I go to try to load a stock firmware and same issue.
I found this article which looks like it should restore access to the EFS partition https://forum.xda-developers.com/galaxy-s3/general/how-to-fix-efailed-to-mount-efs-invalid-t2858056 but whenever I try to load a custom recovery I get FRP lock so it looks like from my reading I am stuck and my relative now has a flashy brick?
Cannot seem to get ADB to work I assume because it has never had USB debugging enabled.
It has never been rooted, custom firmware or anything.
The only thing that works is download mode with ODIN. But since EFS is corrupted/inaccessible and FRP is locked I don't see a solution.
Anyone come across this issue before and how to solve?
It is not under warranty and is slightly damaged so not worth sending back for repair.
Same case
Exactly the same case with me. My device stuck on "Galaxy S7 logo", when I tried to enter recovery mode , got message failed to mount /efs, already tried to flashing with original rom, but still the same.
Then I tried to install twrp,but I got FRP locked.
If anyone can help us maybe there's some steps that I've missed

FRP Locked, Bricked Honor 8 FRD-L14

Hello Guys,
I'm back again (I posted about this issue about 6-9 months ago, a couple users tried their best to help me with it, since than I haven't had any time to fix this issue).
History:
1. Brand new FRD-L14, bought the phone, used it for 1/2 day, fell, cracked screen, replaced it.
2. The phone worked there after, but the OS read "NRM-Test Keys", anyways since I had TWRP installed at that time, tried several different roll backs and such to install a full OS, never worked
3. I did encounter a problem where the fastboot screen would read "PHone Unlocked", but "FRP Locked", at which time I was unable to install anything the error when going through Adb/Fastboot would be "Error: Command No Allowed", a experienced user here did fix it remotely for me, no idea how, but anyways it worked, so back to #2
4. Now the phone has FRP Locked again. So I can get into fastboot, and stock recovery (which doesn't work, states device is unsupported), cannot instal TWRP as FRP is locked
What I need help with is to get rid of this dam FRP Locked issue. I don't understand why it keeps coming back despite me not logging in/putting in credentials when I install the OS.
As I am in the US, Huawei has no authorized repair centers. What a waste!
Any help or suggestions are welcome. Thanks.

Can you get to download mode for the sd card firmware update?

S8+ no download mode

Hello,
I know this has been covered briefly before but I'm trying to look for a solution to a problem.
My friend has been given an ex display s8+ to use, as the company he works for normally just throws them away.
It is on oreo, and as with all Samsung display models, it's locked down with Knox and custom locker. I can't restore the phone (even the lock screen method doesn't work), I can't install play store, I can't root it with adb, and I can't access download mode. I can access recovery, but again factory reset is blocked due to mdm protection.
I feel I have exhausted all areas, so I'm reaching out to see if anyone else has any ideas?
Thank you in advance.
phone turn off volume down + power+ touch bixby not work end for live
Bootloader only flash started good way
my phone g955w with locked bootloader and i can flash all, only boot.img oero and pie not flash
no bootloader, phone locked forever.

Question Does OEM unlock also remove the FRP for factory reset?

Whenever I factory reset my phone reasons maybe because of root or going back to stock I notice that the FRP is now disabled and I can skip past the google account with the skip button. Does the OEM unlock have to do with this? My phone is a factory unlocked model of the Pixel 7 pro.
I'm a bit confused with your question... If you initiate a factory reset from the settings menu, you effectively remove the FRP link to your account. FRP is designed to prevent other methods of factory reset (like from the recovery or bootloader) when an account has already been added to the device.

Yes FRP is disabled when OEM unlocking is enabled.

Question Unable to unlock the phone, data recovery options?

Hello, my wifes stock S21+ crashed and rebooted. It now boots up, accepts SIM card pin code but UI crashes to black screen and reloads when you enter the pattern to unlock the phone. Phone is still locked and it asks for the pattern again. I can't activate developer mode/USB debugging because of this. I can call the phone and answer the call so the phone works, it just doesn't want to unlock.
Is there any way to get the data out? We do have backups but unfortunately yesterdays sons christmas event didn't get yet uploaded to the cloud. The phone has warranty but support said they will wipe the phone. I don't care about keeping phone under warranty, all I want is yesterdays data.
Safe mode has the same problem. I already tried flashing current and older stock firmware with Odin but same problem persists. Is there any other thing I could try?
