Hello,
I have a Galaxy S20 FE model SM-G780G.
I made a mistake while rooting it and I reactivated the bootloader lock.
The phone is now stuck in download mode at startup.
Is it possible to unlock the bootloader from the download mode? (odin gives me an error RQT_close)
Thanks
(all data can be delete)
A few details:
* adb does not recognize the phone (adb devices does not return anything)
* I can't put back a stock rom from odin (message auth failed)
* the download screen doesn't offer the option to unlock the bootloader, just the option to reboot the phone
Solved using latest stock rom version and flashing with odin.

This turns off reactivation lock for when it is stuck on by flashing lowest firmware for your device with Odin and it stays off through mm
This only is confirmed to work on Verizon s5
Doesn't work on g900p
but should work for a lot of s5 models
the worst that can happen is Odin will give you an authentication/authorization error then you just pull battery and reboot and everything will still be there nothing will be lost.
If you somehow manage to get the flash failed error. Where you are stuck in Odin just flash the firmware tar file you were on in Odin before you flashed the oldest firmware for your device in Odin no data will be lost.
Download Odin to your Pc Google it
Then go to Samsung website and download your phones drivers to your computer
Download Samsung Smart switch to your computer and make a backup of your phone with smartsswitch
you may need to use Samsung kies 3 if smart witch doesn't work
Go to sammobile. Com download the firmware you are currently on to your computer
Then download the oldest firmware for your device to your computer from sammobile. Com
This turns off reactivation lock for when it is stuck on by flashing lowest firmware for your device with Odin and it stays off through mm
This probably doesn't work on at&t models or other security restrictive phone carrier models
How to turn off reactivation lock when it is stuck on for other s5 models
First backup using samsung smart switch or Samsung kies 3 then backup other files you want to keep to somewhere you can retrieve it
after the backup remove SD card sometimes it gets corrupted during flashing roms
Download oldest firmware for your device from sammobile.com
Try to flash it in Odin if it succeeds wait for it to boot if it doesn't flash you can't use this method please tell me what models do and don't work I will update this post
If it flashes completely but doesn't boot then boot to recovery and wipe data factory and cache then reboot
if it gets stuck at Samsung screen flash the boot.img or kernel tar file for the oldest firmware for your device that you downloaded from sammobile. Com
Once it boots go through the setup wizard without signing in to any accounts
Then go directly to settings security and turn off reactivation lock at this step sign into Samsung account
If you dont want root or bootloader unlock then you are done
If you want root or bootloader unlock continue
*Some devices may not be able to get root or get bootloader unlock*
Then root using towelroot or cf auto root whichever applies to you
check xda and cf auto root website for your phone model
After you get root check if your boot loader is unlocked by trying to flash in Odin twrp for your device download from team windows recovery project TWRP website
If it succeeds boot into recovery
And flash away
if it fails with authorization error your boot loader is locked so look up how to unlock boot loader for your phone model on XDA developers
Once the boot loader is unlocked Then flash twrp for your device using Odin and boot into recovery then flash away
Thank you Geohot for towelroot KK
Thank You Hashcode and Jrkruse for safestrap
if flashing oldest firmware using Odin doesn't work you can't use this method please tell me what models do and don't work and I will update this post
doesnt work on g900p sprint version
Thanks

@op does it removed the reactivation lock on G900V permanently or temporarily.....?
The g900v model has a seperate thread it is only a full bypass at the moment it makes it possible to use the phone without bypassing setup wizard at every boot thread is here Reactivation lock can be turned off finally for those stuck on reactivation lock

Hi
The device is Samsung Galaxy Tab S2 8.0 SM-T713.
Following is what happened:
1. Installed TWRP and then Installed Lightning ROM v1.0.
2. Restarted the tablet without turning on OEM Unlock.
3. Did not boot by giving error "custom binary blocked by frp lock"
4. Tried installing stock firmware with odin. Firmware installs successfully but when the tablet reboots, it keep showing the glowing samsung logo.
5. Tried multiple different firmwares and eventually tried the latest firmware for the XAR region. Now only that firmware can be installed and all other older firmwares fail in the installation step giving the error "sw rev check fail aboot fused 2 binary 1"
Would really appreciate if anyone could help.
I assume that flashing pit file with the latest XAR region firmware will help boot the tablet but i cannot find the pit file to use.
Please HELP!
I think your problem is the result of flashing TWRP prior to flashing the stock ROM via Odin. Try this. Do a full wipe via TWRP. Then instead of booting into TWRP and then selecting "download" to use Odin, boot directly into download mode by holding Home, Vol down and power. Then flash the stock ROM. This should not only allow you to boot, but should also replace TWRP with the stock recovery. If it still doesn't boot, you should be able to use the stock recovery to perform a full wipe and again try Odin to install stock. But until you get the stock ROM to boot, trying any other ROM is useless.

The problem is that the TWRP recovery is long gone. Its not on the tablet anymore. I cannot flash TWRP because of FRP lock. I can access stock recovery but it also does not allow me to wipe data and factory reset due to FRP lock.
Any other suggestions.
I was able to finally restore the device using the method described in a sammobile forum.
Look at the second post on the thread titled " SmartSwitch: Install & update or replace firmware".
It is a tutorial to reinitialize the device to factory settings using Samsung Smart Switch software.

I can't find that thread in the Sammobile forum but just googling "FRP lock" brings up a bunch of You Tube videos on how to remove the lock. Personally, I've never run into the problem.
I didn't realize from the OP that getting the stock ROM back was due to the lock but rather that the tablet was stuck at the Samsung logo rather that where you are asked for the Google login info.
Just so I've got it right and others understand, before you attempted to install a new ROM, was there an option in settings that would have allowed you to turn off using the lock and thereby have avoided the problem?

All the problems started when i restarted the tablet running a custom rom without enabling the OEM Unlock option in Developer Options in settings.
The lesson i learned the hard way is that you should always keep the OEM Unlock enabled
Hello together,
i bricked my device. Unfortunately now i have bootloader unlock and frp locked !
i cannot install twrp anymore.
can anybody help me with a solution `?
please
Flash stock firmware, once you boot stock, go developers options and enable oem unlock
cannot go back to stock rom... phone locked frp locked, not possible via fastboot to unlock device anymore.
booting into phone is also not possible. and firmware downloading via erecovery failed.
please need help !!!
You could up grade your Phone vía dload o sdcard, when you put the firmware in the sd or internal, it auto flashes, Just flash the signed firmware for your device

If you can not into download mode and have an unlocked bootloader, you can flash stock Samsung firmware with Odin.
