I tried to uninstall system apps. after an unsuccessful experiment, the phone went into the bootloop. Stock recovery was a possible only with data reset. I wanted to restore system with fastboot but it was not available. Just a hard reset. but is no longer relevant. went to the hardreset. ))

Oppo phones have it's bootloader locked, there used to be method to break it but they fixed it in 2020 security update. So ig there is no way to unlock it.

adb reboot fastboot, in the exact same time that the command ends its process, disconnect USB from device, just 2 seconds, and reconnect again, it will show a fastbootd screen with the exact same menu that recovery.
Pressing and tapping on the recovery version also leads to download mode, specially useful for Qualcomm models.
This works for many Realme devices. Anyway, in a locked device, there’s no much to do through.

[Q] How to get into recovery mode without volume buttons?

How can I get into recovery mode on a device that doesn't boot AND has broken volume buttons?
I have a Galaxy Nexus that isn't booting (boot loop) and I can't manually start recovery mode, because my volume buttons are broken.
Is there anything I can do?

You need to get ADB working. You should be able to restore the device that way without having to touch the buttons.
Visit this link for tutorial recovery using ADB.

Unfortunately, adb recognizes my device as "unauthenticated" and I can't send any commands to it.

Hello bro
If you have rooted device.. You can find this app "Android Tuner"
Install this and grant root permissions... And in this tool go to menu and select reboot with full choices
And select recovery

Yep. The only way is to get it repair. Sigh.

boot stuck at "fastboot menu" and "This build is for development purposes only."

boot stuck at "fastboot menu" and "This build is for development purposes only."
After flashing recovery , whatever how many time reboot it ,my phone stuck at "fastboot" menu.
When I click "recovery", Red information "This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission." was flashing then back to menu again.
Any advise?
Thanks~~

Never mind it looks like it is already unlocked based off of the picture. Have you flashed/reflashed TWRP or CWM?

Sorry someone more experienced will probably have to help you. I did loose recovery once i had to flash a couple of different times. I tried locking and unlocking boot loader then it eventually worked. What command are you using to flash TWRP/CWM fastboot flash recovery (Name).img?

No problem. Which one are you flashing twrp or cwm? Maybe changing the recovery/ version of recovery may help. I'm not sure but perhaps certain versions are not compatible with your phone maybe try googling it.

Need Help, tablet in boot loop with Asus logo after flashing stock. Can't access fastboot.

Hello,
I was given this TF300T to check if I can fix it (it was really bad soft brick with data partition not being mounted by TWRP and giving on boot that it is encrypted).
I tried flashing stock and after stock ROM was flashed (followed the guide I found here) rebooted as per the guide.
Since then the tablet is in a boot loop, I can't turn in off completely and upon trying to restart it while holding volume down I still get into the boot loop. With volume up, it vibrates one and then "connects" to my computer as an unknown device.
If anyone has any idea on how to fix it, please respond. All help is welcomed.

if if vibrates, it's not a TF300T... because the TF300 doesn't have vibration...

Well, based on the kernel, and what it did say in the TWRP recovery before I tried flashing stock it is TF300T. And after checking online, the model for Bulgaria does have a vibration motor.
How the question is how can I force it to boot into fastboot mode.

Before the bootloop starts again hold "Volume" down and you will get into fastboot mode.
After that you may do a Buster99: (1) Unrecoverable bootloader error but not Bricked! | XDA Developers Forums (xda-developers.com)
BTW, if you cannot get into fastboot mode, please, dowload "Minimal ADB and Fastboot" and try ADB.

So I tried that, but it still doesn't get me into fastboot mode. I also tried it with the reset switch and it still gets into the bootloop and nothing connects to the pc. However is I hold the volume up button, the display goes black and it does connect, but my pc doesn't recognize the device and can't find drivers. When I do the volume up it connects as an "APX Device"

In this mode it is still not seen either from ADB or Fastboot (tied both with Google Platform Tools ADB and Fastboot and with minimal ADB and Fastboot).
Seems there is a driver problem. Hopefully you will get it. So you may try the attached driver.

That was helpful, the tablet is now connected in APX mode. I tried finding the NVFlash tool for the TF300T, but it is dead and APX mode itself doesn't let you use adb or fastboot commands

what is your question you need to be more specific than this
just hold power button for more than 10 seconds
or go into recovery mode by pressing power button, and from there shutdown or restart it

Not working need to unlock bootloader

QUALCOMM Crashdump Mode on boot even after using MSM tool

So long story short: I was on Flamingo OS A13, got a crashdump mode all of the sudden, I tried flashing again without success. Then I used MSM tool to go back to OOS 11 and after completing, the device just shows the OnePlus logo, screen gets distorted (see image below) and goes off. I try turning it off and on using all the buttons, and I can access Fastboot mode and Recovery only without any problem. But when I try to boot normally, it crashes on the OP logo again and goes into crashdump mode. I tried every latest MSM tool (OOS9, OOS10, OOS11).
Not sure what else to do.

for some reason I always get the same error after using msm tool.
try to boot to twrp recovery using all in one tool or any other way. then flash OOS 11 on both slots (don't forget to format data).
you should be fine. tell us if you managed to fix it by any way

Thanks for your reply. Unfortunately I can't boot to twrp since MSM locks the bootloader and I can't unlock it unless I boot the device first, which is the problem.

Unfortunately, no. After researching about the issue, I found that it's a hardware problem where the RAM or motherboard needs to be replaced. I ended up buying another OP7Pro and decided to get my hardbricked one fixed sometime later.
