How to flash stock rom when my phone is stuck in flashboot mode, like I can't even open TWRP in cmd prompt as an img file. How to flash other that that?
Typically one presses the power button continuously for at least fifteen seconds. The device will vibrate once and restart in normal mode.
If this doesn't fix the issue, then, if you can access the phone by means of Fastboot executable, you can try to exit Fastboot mode running this command sequence
Code:
fastboot devices
fastboot reboot
Fixed?

Hello.
Earlier today I wanted to try a new JB rom to replace ICS so I transfered it into SD card and tried to reboot into recovery.
Instead of getting to recovery, I got stuck in fastboot mode, so I'm assuming recovery has been damaged.
After a whole afternoon of researching this forum I tried for several times this tutorial in order to install a recovery and afterwards a ROM (http://forum.xda-developers.com/showthread.php?t=1088046) and similar ones in both Mac OS X and Windows 7 (tried both USB 2.0 and USB 3.0 so its not a problem from USB) and I didn't succeed at all.
When I am using Windows 7, when I use "fastboot erase recovery", I keep receiving this message "waiting device". If I write "fastboot devices", I don't get results.
When using Mac OS X, I can get via command line to the folder "platform-tools" where fastboot is located but if I write "fastboot erase recovery" or something, it says "command not found". I've read it could be because I have to set fastboot as an environmental variable, but I having trouble setting it (Mac OS Lion).
Thank you so much for reading. Please help me!!! Any clues would be really appreciated!

UPDATE: I finally managed to communicate with the device.
I used the following commands from this tutorial http://androidforums.com/optimus-m-all-things-root/382525-guide-get-out-fastboot-mode-2.html
fastboot erase boot
fastboot erase recovery
fastboot erase system
fastboot flash recovery
The problem is, now I'm stuck at LG Logo, can't access fastboot... Please help, I think it's even worse now.
boot rom, pull out battery and boot normal, it does or not? if it does use terminal emulator or adb push to install custom recovery, adb will work in fastboot if you had checked android debugging

I don't understand what you mean by boot rom. Every time I turn on the phone, (normal or as POWER+HOME+VOL DOWN) it goes into fastboot. When I pull out the battery, and power again it goes again into fastboot...

ok, read here http://forum.xda-developers.com/showthread.php?t=1088046 do exactly what says in this thread
Hey folks,
i have a problem with my shieldtablet. The fastboot doesn't work properly. I cannot load anything via "fastboot flash blablabla.img". Minimal ADB and Fastboot just shows "waiting for device" and if i check the devices via "fastboot devices" is just shows nothing but the normal command prompt.
Then i did a mistake and flashed the twrp 3 version with an older one, so i am unable to enter the recovery-mode. If i chose Recovery Mode via bootloader (or if i restart the tablet into recovery mode) it has a short bootloop and then after some trials it starts normal into Blisspop.
How could i flash this without the fastboot? Is there any trick i could use?
The tablet is unlocked. I had several custom-roms installed. Currently Blisspop 6.4 without playstore.
That looks like your PC is not seeing your tablet. Boot into fastboot mode, connect it to your PC and look in Windows device manager for the device.
Thanks a lot! ADB worked fine on Win10. Last time I flashed the recovery was on my old Win7-System. It seems, that the Upgrade deleted just the fastboot drivers.
One last question: is it normal, that if i chose the fastboot protocoll entry on the bootloader, that it restarts the bootloader?
Yes, that's normal. The menu entry is redundant because when you see it you are in fastboot mode already.
hi my oneplus 7 pro 1910 stuck at bootloader and when i press start or recovery it gets back to the bootloader screen i cant even turn off the phone
i accidentally wiped all partitions in twrp and made a format .
anyhelp ? ive tried to do the fastboot rom flash but my pc doesnt detect my phone
i tried almost every solution i found but nothing works
Your bootloader needs to be unlocked to use a fastboot ROM.
Is it unlocked?

Yes it’s unlocked , any help
Search on the fast boot rom thread for the fast boot rom version you were last on, i have used this many times and it worked.
One thing to note, after it flashed everything , I ended up in crash dump error. I went into stock recovery and wiped/formatted my device and it boot up great.
https://forum.xda-developers.com/t/msm-tool-guac-for-all.3934691/ - just follow this guide
One thing that worked for me is when your phone is plugged into your pc open a command prompt and type fastboot boot twrp-*.img (make sure it is the .img not .zip), and from there download the twrp installer .zip and flash that, reboot to recovery, and install the OTA for your device (OTAs can be found at this thread).
If it fails to boot and gives you an error, try fastboot getvar all to see which slot is currently active then do fastboot --set-active=*inactive slot letter* then fastboot --set-active=*original active slot letter* then try to boot to the twrp .img from fastboot again. If fastboot doesn't detect your device at all, try seeing if adb devices outputs anything, and if it does type adb reboot bootloader
Good morning!
While attempting to flash a stock MIUI 10 ROM into my Xiaomi Redmi Note 7, to downgrade back to Android 9.0 due to some app compatilibty issue, I messed up big time and my phone is now stuck in a loop where the screen turns on, nothing shows up, then it restarts, going off for a few seconds and turning on again.
Power Button + Volume UP successfully brings me to the stock recovery 3.0 from xiaomi.
Power Button + Volume DOWN fails to bring me to the fastboot mode.
If I select the Connect with MIAssistant in the recovery the phone will show up as "sideloaded" after using the command adb devices, but the MIPCSuite app does not see it and the command adb restart bootloader also fails to bring up the fastboot mode, it just gets stuck in the loop again.
More context on what went wrong and caused this: I followed an online tutorial to flash a rom using the MIFlash app, so I unlocked the bootloader and tried to flash the rom usin xiaomi's tool. I got a failed to check sparse crc error code and it went downhill from there when I tried to fix things reading multiple threads on the issue. I tried deleting some lines from the flash_all.bat file and tried to flash it again but then the flashing process went seemingly forever so I aborted the operation and now this loop happens. I tried a few more times but with no success.
The first time I tried to use the tool I used the clean all and lock option so I'm not certain if the miflash tool locked the bootloader regardless of the outcome of the flashing attempt.
Is there hope? Can I fix this phone if I only have access to stock recovery and nothing else (although it shows up in adb devices but can't get into fastbootmode) ?
Thanks a lot to anyone who took the time to read and possibly help.
Both ADB and Fastboot are Android-side launched by device's bootloader. If you can't enter Fastboot mode then my guess is there is something is wrong with curently installed Android.
BTW: If you lock device's bootloader then bootloader attempts to load device's Stock ROM.

I see.
What can I do to try to fix this issue?
I finally managed to fix it through the Emergency Download Mode (EDL). It requires Xiaomi Authentication which I bypassed using this guide: https://www.droidwin.com/fix-mi-account-authorization-unbrick-xiaomi-edl-mode/
With that setup I flashed a stock rom using the MiFlash tool.
I am using Poco X3 Pro. Global version. I think I flashed the ROM incorrectly. Resulted in my phone forever in fastboot. Can be detected by PC in the platform-tools CMD, by typing fastboot devices.
However I cannot get into recovery mode by pressing vol up and power buttons. I tried ”fastboot reboot recovery”, my phone reboot into fastboot again.
What should I do now?
Is there a proper guide step by step?
I unlock bootloader and want to install magisk to root my phone as I require root access. However it seemed difficult to me to root the phone.
