Adb in normal startups and fastboot in bootloader mode ( after pressing power + volume down ) are not working
Could anyone tell me how to solve this Thanks in advance
Have you enabled USB Debugging?
I don't think there's an option to enable USB Debugging in the original system before getting into fastboot and rooting the device.
Are you able to boot into the ROM? You just can't use adb & fastboot?
Yes I can boot into the ROM. It's the original ROM. And I can't use adb or fastboot.
You have a start button? Try start + power to boot into fastboot mode.
Thanks for your reply&time.
I believe that power + volume down is the way to boot into fastboot now, and after booting into fastboot and connecting the USB line, (fastboot devices) command in the computer (tried Mac OS X 10.8, Windows XP virtual machine and Windows 7) shows no device connected. When using start+power, my device boots normally into the original rom.
All right. I think I just got rid of the fastboot issue. There's something missing with the driver. I'll post my solution after I verify it and flash DPRom successfully.
The problem is acutually pretty silly. A proper adb driver is required for fastboot.
I installed tineprogramming's adb driver to fix it.

Hi FriendsIn this post i will tell how you can open recovery mode in all 10.or Devices. I have 2 methods to do this.
So Let's get start
Method 1 - Using Pc
Requirements - 1 Usb Cable and PC
First You Need To Install Adb Drivers On your PC and Download Platform Tools zip file for Windows PC by Clicking This Linkhttps://developer.android.com/studio/releases/platform-tools.html. Now Extract File and Open platform tools Folder and Press Shift Key then Right Click. Now You Will See Open PowerShell window here, Click It.
Open Your Phones settings and go to about Phone. Click Build Number 7 and more Times it will Open Developer Option. Now open Developer Option And turn On Usb Debugging.
After Opening enabling Debugging Connect your Phone Using Usb Cable.
Now Run Commands
"Adb Devices"
Your Device Prompt For Debugging. Grant It.
If Your Device Appear In PC Run Next Command
"Adb reboot recovery"
Now your phone automatically boot into recovery mode.
Method 2 - Without PC
Requirements - Only Your Device
Simply Turn Off Your Device. After Turn Off your device Press Volume Up key Then Power On Key. After Vibration release all keys.
It will boot Recovery Mode
Now You Can Wipe, Install Update, and Unlock Bootloader of your 10.or Devices.
This Is A Hint To Increase Development Support For This Devices. So Developers Try To Unlock Bootloader And Start Making Roms and recovery etc. After Any Rom or recovery Roll Out for this device I will Root My Device and Just Install It on my device.
Thanks

Tenor e no command error
Hello everyone, myself ramchandra, I have tenor e phone and when I m trying to open its recovery mode then it is showing me no command screen.
Will some pls help me for this.
Thanks
Ramchandra.
Press power key for 2 to 3 seconds then press volume up key along with it this will let you in recovery mode.
My phone. - Galaxy A51, One UI Version is 4.1, Android version is 12, Product Name – SM-A515F.
Stock ROM up to date.
I can boot into download mode, +/- volume, connect to pc. Works just fine.
But + volume & power boots into safe mode; - volume & power boots into safe mode; +/- volume & power boots into safe mode; +/- volume only boots into safe mode. I have ran out of button sequences to try.
What is wrong with my phone, is it impossoble to boot into recovery mode on my model of phone. This is why I cannot install TWRP as when I install via Odin, it will not boot into recovery post installation.
I am stumped.
Hello!
What is about phone: is it bootlooping or is it in downloading mode?
Other question: from what source did you download the twrp.tar file?
You should be able to force a reboot to recovery using ADB. Enable developer options, then enable USB Debugging. Download the SDK Platform Tools and open a command line in the platform tools directory (where you find the fastboot, adb, etc programs)
First, type adb devices. ADB will then start the ADB daemon.
Next, connect your device via USB cable while unlocked. You should get a prompt on the device screen requesting USB debugging authorization. Go ahead and grant it.
Then, type adb devices again. If you authorized USB debugging correctly, you should see your device listed.
Now, type adb reboot recovery. Your device should reboot into TWRP.

Guy, to complete the TWRP installation, it is needed to flash Disable_Dm-Verity_ForceEncrypt from TWRP, otherwise the device will not boot properly

It's in Stock now. But it was stuck in a bootloop, but could boot into download mode. These are the recovery's which all installed but I could not boot into. I cannot boot into recovery now I am in Stock. It's as if there is no recovery option for my A51.

I was stuck in a bootloop and could not boot into TWRP..
Unless there is a way to flash Disable_Dm-Verity_ForceEncrypt in downlad mode using Odin?

Hi I am back in stock now, so no TWRP installed. Would this method boot you into Stock recovery?
Do I need to be in download mode or just normal mode when connecting the phone to the pc?
Hello, can you say what version of Android your phone on?
If it is on 12th, then I would say, that the problem is, that this version may not fully supported for TWRP working
Because as I tried, there was a fail in the procces.
Sorry, i did not see that you have already written about it
Yep, think I will have to download Android 10 stock rom; and hopefully be able to install 10 via Odin from 12 back to 10.

ADB commands must be issued in system. The alternative would be from fastboot but it doesn't seem you can access that.
Try flashing TWRP again, but immediately hold Volume Up during boot to force booting into TWRP. Newer Samsung firmware does seem to have some sort of security measure that will replace a custom recovery, so you'll have to flash the Multidisabler to disable stock recovery auto-restoration.

I do not want to mislead you, but you will not be able to roll back from Android 12 to Android 10, because the current binary version of your phone (5) cannot be changed to lower one (4).
Maximum as you can do, is to downgrade to the 11th version and there, as I think and tried, the Twrp+vbmeta_A11.tar recovery file will be flashed sucessfuly and you will be able to enter TWRP without issues like bootloop.
Other problems are, as I think, that you may forgot to enable USB Debugging on your phone and authorize it with your computer, you may forgot to set the default USB Configuration as data transfer (MTP), or even you may not unlocked the bootloader.
I think they are the reasons because of which you could not enter TWRP, because, as I have tried to flash One UI 4.1 Android 12 according to this thread recently: https://forum.xda-developers.com/t/...ecovery-project-v3-6-2-android-11-12.4400869/
everything has been sucessful, both flashing and entering and following rebooting to Stock system.
Or you may even not removed the check mark from the parameter "Auto Reboot" in Odin

Cheers for that, just downloaded Android 10, took me twelve hours to download, so its no use to me. I need to download Android 11.

Yep did that.
I have access to fastboot and EDL mode. Does this mean that I can also access the mode that will show the phone after the adb devices command?
If device gets booted into FASTBOOT or EDL mode then it can't additionally get accessed via ADB: this can only get achieved when device got booted into RECOVERY mode.
To clarify:
ADB ( short for Android Debug Bridge ) deals - as its name implies - with a device's Android OS.
FASTBOOT deals - as its name implies - with device's bootloader, if that isn't bricked.
EDL ( short for Emergency Download Mode ) - specific to devices with a Qualcomm Snapdragon chipset - deals with the device itself, is used if bootloader is bricked.
Thank you for your quick help. Is it possible to access adb during bootloop?
I entered something called recovery mode, but the computer doesn't recognize that any device has been connected - adb devices doesn't see anything either.
On one of the pages I read this information:

Unfortunately, there really is no “recovery” per set, yet. There is a mode where one can factory reset the phone which can be reached using the hardware buttons. However, from there, you cannot do anything other than reboot to a simpler form of phone. There are no options to go into bootloader or Fastboot mode. ADB won’t get you there. Sometimes, using ADB, you can boot into a simple android recovery with no command! There you remain until hard booting back it back into full functionality. Developer is apparently working on it

Hi Ed Reynolds,
Thanks for sharing your knowledge. We appreciate your efforts. Yes, stock recovery doesn’t offer many options. One has to install a custom recovery like TWRP to get over this problem and to maximize productivity.

That is correct. but, in order to install a custom recovery, one must be able to get into bootloader, in some way. Either through physical buttons or through the ADB tool. forget about using the physical buttons – they get you to the recovery that you mention, but cannot get you into Fastboot (bootloader) mode. If you use the ADB tools while in this particular recovery mode, and try to reboot into bootloader mode from there, it boots back into the system. So, using that route, you cannot ever get to a place where you can install TWRP or anything else, for that matter – including applying an unlocking code if one were available. Next, if you try to get into recovery mode using the ADB tools (not the physical buttons, you do arrive at a more “conventional” recovery — with the picture of the little Android symbol, etc. However, there are no commands to use to get into Fastboot or bootloader mode. I have had this problem before and sometimes, using the physical buttons, you can reveal commands at this stage. However, even here, no combination of physical buttons reveals any commands. Then, as a last ditch effort, you use the ADB tools to boot into bootloader mode, you return to the system! The result is, again, you cannot install any sort of custom recovery because there is no internal or external way to flash it. If you have overcome this problem, please share! It is very frustrating! Thanks. Ed
Does this mean that I will need to flash custom recovery to gain access via adb during bootloop?
Android's Recovery is nothing else than a minimalistic working Android OS, comparable to Windows Recovery Environment ( WinRE ), so it's accessible via ADB.
A Custom Recovery ( like TWRP ) isn't needed at all, because such a only is an UI version operable by touches.
So if Windows don't see device when is in recovery mode (but recognize correctly when is in fastboot mode), there is a problem with drivers?
I want to access to adb pull for backup. Device is rooted with unlocked bootloader and allowed USB debugging and no PIN password, but bootlooped after trying to restart after uninstalling YouTube app
OMG
when in Recovery mode then you've to connect device via USB-cable with computer and you can launch adb pull command on computer.
When I in recevery mode, computer not recognize it - adb commands not working, device manager don't see any device. When I on fastboot or EDL, computer recognize phone, commands working and device manager shows device on list
Then obviously USB Debugging didn't get enabled in Android's Developer Options.

As the other user said, USB Debugging is not enabled or proper drivers are not installed. The drivers for fastboot and adb are different. Search for correct drivers, disable driver signing in Windows and install the drivers.
