This is for the Galaxy S20+ Exynos. I tried restoring from backups in TWRP. The phone is stuck in a boot loop. I tried pressing the volume up/power button to get into recovery but nothing happens. At what exact point should I do it? I also tried pressing the volume down/power button to get it to shut off but it didn't work. I tried connecting it to my computer and running adb. ADB devices lists it, but I can't run any other commands as it says it's unauthorized.
Got into TWRP The button combination didn't work at first, but if I had the USB cable plugged into the phone and computer then it could restart to recovery.
Once in TWRP do a factory reset by wiping data, cache and dalvik.
Out of curiosity does anyone know why Samsung phones sometimes can't get into certain modes without things plugged into its USB?

stuck on t-mobile logo
I can neither get into recovery or boot the LG D851.
I can get into download mode by connecting to computer and pressing power up button. however ADB cannot detect the device even-tough device manager shows it with error code 10.
My phone was working fine on rooted lollipop except that i had problem with deleting files so i went into recovery and deleted some files related to Logitech harmony app that wasn't working. In also fixed permissions.
Now the phone seems soft bricked and stuck on t-mobile screen all time. I can get to hard reset screen but i dont want to do that
any suggestions?
solved
did Master reset with hardware keys. https://support.t-mobile.com/docs/DOC-11920
Press and hold the Power and Volume down keys on the back of the device.
When the LG logo appears, release and then re-hold the Power key while continuing to hold the Volume down key.
The Factory data reset screen appears. do the factory reset ant it takes you to the TWRP recovery.
i connected to PC and copied the data from phone to PC
then restored the previous backed up image from TWRP
and the phone is working again
**the phone was stuck in the bootloop because of fix permissions done from TWRP***
This morning I was experiencing an issue called "MTP host has stopped" while playing a heavy duty game in my Galaxy Note 2. I thought doing a reset would fix the issue. So I reset my phone then it rebooted in TWRP recovery mode. I then did a clean wipe selecting all the boxes as in data, system, delvik, cache, Sd etc. and rebooted my phone. The phone rebooted fine but it now stuck in Samsung logo screen as I have wiped out my OS.
The worst part is, My power button is already broken. Which means I can't enter into recovery mode by pressing Vol up + Home + Power.
I read other forum topics on whether there's any solution on how I can still enter to download mode. All I found is that I either need a working power button or I need to create or purchase a USB Jig that will help me force my phone into Download mode.
But I would like to avoid using USB jig. Is there a way?? Please Help!! :crying:

Hi,
After wiping /system on my Razer Phone, I tried to sideload an image, and the recovery crashed and the phone rebooted. Since, it has been restarting indefinitely, being on the Razer logo and the "Your device is insecure" message.
I have tried to hard shutdown the phone with power+volume up, then holding volume down and plugging the phone, but I was unable to get download mode working...
Volume up then plugging in the phone to my computer did not help either. Both volumes either.
If someone has an idea on how to get it into download mode, I'd really be grateful. Thanks.
Try power and up for nearly a min sounds stupid I know but forces a full full power down. Otherwise wait a few days for the battery to die then plug into pc with vol down held.
Tried both. I even opened the phone, unplugged the battery, then plugged it again to force a shutdown. It never got into download mode
What type of USB cable are you using?
Hi everybody, yesterday I was playing with my old Galaxy A50 trying to install a custom rom unsuccessfully.
I repeated the procedure three times installing TWRP and then Havoc OS but every time I tried to reboot from TWRP to OS I was stuck at the warning screen saying that the phone bootloader was unlocked and booting into download mode to reflash TWRP was blocked as it showed "only official binaries can be installed" (yes I installed Samsung disabler but still).
Still I was able to get the phone into download mode and reinstall the stock firmware as it seemed to be the only way to install and boot TWRP.
But at 4th time repeating the process I got frustrated, shut down the computer and left the phone on the warning screen still connected to computer usb cable.
Then I got back and noticed the phone was off as the battery died.
Indeed the battery died, so I put the phone in charging and after it reached 100% I tried to boot into download mode again to reflash stock firmware.
But here's the strange thing, I cannot boot into download mode anymore as pressing vol up+vol down while connecting usb cable, shows the lightning charge logo for 5 secs and then reboots infinitely with the same pattern.
If I force reboot by pressing vol down+power it shows the Samsung logo with the warning below it, then skips to another screen with another warning suggesting to press power button to continue (which does nothing) and after a while reboots to samsung logo.
So it doesn't seem it is bricked, it looks more like a battery controller fault, so I tried to detach the battery flex from the board, hoping it would reset the controller but it's still the same.
Also I tried with the flex detached and still no download mode is possible.
Was the download mode somehow erased? (if it's even possible considering it's the motherboard firmware)
If you need photos, videos or even a call on zoom, Skype, webex I would be glad to show you
same i got the same problem i can't find nothing for this when i press volume up and down and put the otg cable its simply charges but it gets stuck on the logo image there's no way to fix this but the only way is to open the phone,change the emmc and put one from samsung,close the phone flash a custom rom and you are done.
If you can enter recovery, do it. As soon as your phone gets into it, select the power off variant and then try to enter the download mode.
It seems like you did not unlock the bootloader, did you?
The bootloader Is unlocked i can't enter in the recovery because the phone locks on charging logo and its fully charged but when i try without charger It doesn't start.
Hello,
my wife got a S21 FE (SM-G990B/DS VD2). Yesterday it started to reboot over and over out of a sudden, showing the samsung logo first, followed by the knox logo, then shutting off and on again. Tried several guides to enter Recovery or Download Mode. The only thing that worked was entering download mode by pressing Vol up, down and power while a USB-Cable is plugged in, but as soon as i press the vol up button to pass the "warning screen", it shows some phone specs for a couple of seconds, shuts off and starts bootlooping again. After some hours, the phone once entered recovery mode when it lied next to me for about an hour. Tried to wipe cache, but just got an error I can't remember right now. Hoped it fixed itself when it made it to recovery and just rebooted to see if it works again, but then it just keept bootlooping again.
Since then I couldn't figure out why it once booted to recovery on it's own nor why I can't force it to enter recovery by pressing vol up + on.
Still hope it's just a faulty update or bug, but feels very much like it's a hardware related issue. Replacing the phone won't be an issue, but I'd really want to save data on the phone as my wife didn't make any backups and really wants to keep the photos.
As I just found guides that included recovery or DL-Mode, which are both no valid options for my case, I'd be thankful for any ideas to fix the phone or at least gain access to files before replacing it.
So.. did anyone come across similar issues and found a solution to revive the phone or are there any "unpopular" ways to recover samsung phones out of this state?
Edit:
Turned off completely overnight, booted once to system, looped again and now it's working like nothing ever happened. Got no clue what caused it or why it is working again. Saved everything for the case it happens again.
Wouldn't trust that device anymore, but my wife wants to keep it.
¯\_(ツ)_/¯
I would just like to reply here and add my own potential fix and also would like confirmation that it would work.
So I have a SM-G996B in a boot loop which returns a 'fs_mgr_mount_all' error. Possible to reboot into recovery mode, cleared cache and restarted bootloader etc with the same boot loop. Powered off and connected to PC for Download mode for ODIN recovery but upon pressing volume up, it then restarts again so Download mode recovery is impossible.
I know however that Developer options and USB debugging was enabled on the device as well as unlocked boot loader. I was able to download the correct original stock OS based on the PDA , CSC and Android version.
I have then installed the latest ADB software on my PC and Samsung USB drivers.
By then rebooting into recovery mode, I have the option of 'Apply update from ADB'. I have then confirmed the device connects using the ADB devices command.
I would like to clarify one thing however. I want to keep the user data at all costs. By using the stock firmware and renaming as update.zip, will it use the HOME_CSC and not the CSC file? If not would it work if I open the zip and remove the CSC before re-zipping to make sure?
Thanks

Similar issue with same phone. In a bootloop after trying to root. None of the button combinations have worked for me, for the past several days.
Tried powering the phone off for the whole night.
When connected to the PC shows phone is in recovery mode via adb (blank screen though).
Want to know how to get into DL-mode, guaranteed.
Got to DL mode by pressing vol up + down + power + usb cable connected in PC and phone. However, couldn't do anything there, but maybe you can
Also, phone is still working and I still have no clue what was the problem and what fixed it.
