I have a Point of View PROTAB 3XXL. I am trying to flash a boot.img, without reason 'cause I just want to experiment with my tablet. But the problem is that I can;t get in bootloader/fastboot mode! I can get into recovery by using vol +/power. But I just can't manage to get it in bootloader.
I tried this:
vol -/power : just boots device
vol -&+/power : doesn't boot it at all
adb reboot bootloader : same as above; nothing at all. First have to reset before I can turn it on.
adb reboot-bootloader : "" ""
Quickboot Bootloader option : "" ""
I dont have any options left :'( so does anyone have an option or solution?? Is it possible that my POV just doesn't have a bootloader.
T.I.A.!!!

Hi, I cannot change the bootloader of the huawei u8230 android 2.1 A1 branded, carrier lock unlocked.
I was able to install z4root.apk and was able to get temporary root with the following command
Adb shell
Su
#
Then I tried to install recovery-clockwork-3.1.0.1-u8220.img
with install-recovery-windows.bat
and with fastboot command Fastboot flash recovery recovery-clockwork-3.1.0.1-u8220.img
but both did not work, the bootloader is still the original.
What can I do to change the bootloader?
Do I need permanent root? How to I get permanent root?
Please help
Thanks
wrong combination of keys

that worked.
call end + vol- + power is fastboot
call end + menu + power is bootloader:laugh:
I am very new to this, I rooted my Moto G4 and now I need to download SUHide in order to play Pokemon Go. When I try to enter recovery via my fastboot/abd folder I get a < waiting for any device > message. When I hold down the power + volume down button my phone just turns on as normal without entering bootloader even though my bootloader is unlocked. I tried downloading an app that loads recovery for me but when I tried that I got a "no command" screen with a little green robot.
From what I've read, it's possible I didn't flash my trwp properly? I don't know how this is possible since I just rooted my phone. I would appreciate some help, I'm afraid to take any random guesses at the risk of ruining my phone. Sorry if I'm missing something obvious or not giving enough info, I'm not very tech savvy.

Try power plus volume up button to go to fastboot mode.
If it not working then connect your android to pc and enable adb. Type "adb devices" enter then type "adb reboot bootloader" and enter. It boots your android in fastboot mode.
If adb commands not working then install adb and fastboot drivers and try again.

In most devices, volume up + power boots up the recovery options, volume down + power boots the device into fastboot mode (volume buttons first plus power, pressing power button first would boot the device normally).

How did you install the custom recovery? Try flashing the recovery.img again (I'm guessing, since you have root, that you did not "flash" (fastboot flash recovery recovery.img) TWRP but just "boot" (fastboot boot recovery.img) it and installed SuperSU).

Okay, so that did work, and I was able to enter fastboot mode. However, once I scrolled down to "recovery mode" and tried to enter, I got the same "no command" screen.

I used the official moto g4 root guide on this website to root my phone and I'm pretty sure I booted, not flashed, the recovery img (mine is named twrp-3.0.2-0-athene). So, I tried using the command you provided to flash the recovery img and I got a < waiting for any device > message in the command prompt. My phone is plugged in and my recovery img is in the adb / fastboot folder. Any idea what this means? Thank you for the help guys
edit: If it helps to know this, my phone has usb debugging enabled and it is recognized by my pc. I type adb devices and my moto g4 serial number does indeed show up.

If you are trying to flash twrp recovery on your android then rename your twrp to recovery.
Boot your android in fastboot mode,
Navigate to folder that you have recovery. Press shift and right click and click on open command here and type "fastboot devices" and enter
"fastboot flash recovery recovery.img
It flash your recovery to your android.

Did all that, getting:
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
(bootloader) has-slot:recovery: not found
error: cannot load 'recovery.img'
Also, per the suggestion of other users on these forums, I tried to hold down power and press volume up during the "no command" screen after attempting to enter recovery. That sent me into Android Recovery but it's not the twrp platform I used when originally rooting my phone.
How did you unlock the bootloader? have you tried: fastboot oem unlock?
You need to "allow oem unlocking" on developer options (which I guess you already did). Then reboot in bootloader: (a) adb reboot bootloader. In fastboot, you need to unlock the bootloader first: (b) fastboot oem unlock (or unlock-go). Then you can try to flash that recovery.img: (c) fastboot flash recovery "name of the file.img"
edit: fastboot oem unlock restores the device to factory settings. You need to configure and enable again "usb debugging" and "oem unlocking" (which are disabled by default). You can then proceed to fastboot flash
For the life of me I can not get my wife's phone into bootloader mode. I have read tons of threads that all say to either hold down power and vol down OR plug in the usb cord (connected to computer) while holding the vol down button.
The power+vol down results in the recovery mode and the other causes a vibration then goes to the %charging screen.
I have adb working cause it returns the device number and also reboots... BUT neither <adb reboot recovery> OR <adb reboot-bootloader> does anything but reboot normally.
Here's the deal, I am trying to get her stock phone to run Android Pay but it fails the safety net. There is a chance that I unlocked the bootloader but without having access to fastboot I can't run <fastboot getvar unlocked> to check.
So my questions are:
Is there some way to get into fastboot that I am missing?
Is there a way to know if the bootloader is unlocked besides fastboot command?
Any thoughts on reasons a stock phone would fail safety net besides the unlocked bootloader is welcome also.
Thanks.
PS. This V-10 in nothing like ny Nexus phones. LOL
I had my OPX running nicely with TWRP bootloader and AOSIP 8.1 rom, and then I went and relocked the bootloader with "fastboot oem lock" command. Now it just vibrates and flashes up the OP logo and "powered by Android" screen, and continuously reboots. Only thing I can do is hold the power button till it turns off. Holding the vol down button and power buttons aren't getting it back into fastboot state. What's the best way to recover from this state? Kind of hoping it's as simple as getting back in somehow and "fastboot oem unlock"?
OK, managed to recover it by getting into fastboot and unlocking the bootloader again. Bit of a relief. "Fastboot oem device-info" is now reporting device tampered as true, it was previously saying false. Is this different to being rooted? When I run a root check app it says the device isn't rooted. Everything is working fine apart from the Barclays banking app, which it seems is very fussy about non standard firmware, unlocked bootloaders, and having TWRP installed. Is there any way to make it happy? Kind of frustrating to loose that, all my other online banking apps work.
Did you tried with Magisk activating the Hide option for the Barclay's app?

No, not yet. I've been reading about it on XDA, but seems a bit hit and miss whether it Magisk can fool the latest Barclays app?
I also have another OPX (my current main phone) running stock Oxygen 2.2.3/Android 5.1.1. Bootloader is locked and it's not been rooted. I would really like to transfer all my saved wifi network passwords over to another device. They don't seem to go into google backup from the OPX, and I'm struggling to find another way to get them off without rooting. Obviously, I can't unlock the bootloader because it'll wipe everything off the phone. I did try Kingroot out of desperation (seems to be the only way to root with bootloader still locked?), but even that wouldn't install. So I'm stuck on that as well.

Noob Guide:
1. Download latest TWRP on computer.
https://dl.twrp.me/onyx/twrp-3.2.3-0-onyx.img.html
2. Download minimal adb tools and install it (Folder installed at C:\ProgramFiles\Minimal ADB and Fastboot)
https://forum.xda-developers.com/showthread.php?t=2317790
3. Transfer Twrp file to 'minimal adb and fastboot' folder.
4. Switch to fastboot in mobile by pressing "vol up + power"
5. Connect to PC using usb cable
6. Press "Shift" and right click in 'minimal adb and fastboot' folder, click on "open powershell(cmd) window here"
7. Type " ./fastboot devices "( it should show you fastboot serial number)
8. If bootloader is locked, unlock it by typing " ./fastboot oem unlock "
9. Install twrp by typing " ./fastboot flash recovery twrp-3.2.3-0-onyx.img "
10. Boot into twrp by typing " ./fastboot boot twrp-3.2.3-0-onyx.img "
11. If TWRP shows up,
Download your favorite desired Custom ROM (my fav any Oreo ROM) on computer and transfer it onto your mobile.
Download Gapps(any package nano,stock etc..) and transfer it to mobile.
12. In TWRP goto
Wipe >> swipe to factory reset
Advanced wipe >> select "System,Cache,Dalvik Cache" and wipe it
13. In TWRP goto
Install >>select ROM,gapps>>flash it.
14. Reboot
That's it.:laugh:

I installed the android 10 update bit suddently when i rebooted it got on bootloop. I tried to go recovery and format it but it dodnt worked. Tried using mi flash but nothing happens. There is any way that i can unlock bootloader? (Cant boot and unlock oem)
Use the following codes on the adb after entering fastboot mode
First enter fastboot mode by pressing power and volume down until fastboot mode starts(about 10 sec)
Then enter the code
1) fastboot flashing unlock ( press enter)
2)fastboot --set-active=a (press enter)
Then run mi flash tool. Your phone should start.
Doesn´t work because the phone is locked and i can´t unlock it because don´t boot. That´s the problem.

Since your bootloader is locked and this loop occurred while officially updating you could claim the warranty and they will fix your phone for you.
