[Q] My OPO is not allowing fastboot - ONE Q&A, Help & Troubleshooting

Hi,
My OPO has been booted with TWRP before but is not rooted at the moment. I have unlocked the bootloader a month ago to flash the 5.0 lollipop update this was fine and everything worked. But now i am not able to boot into fastboot mode again as it reboots when I plug in a USB. I have no idea what may have caused this.
Thanks

How do you mean that you're not able to boot into fastboot mode again when you plug in a USB cable?
The way you boot into fastboot is with the device shutdown and that you hold Vol Down + Power,

Fastboot not responding at all.

Firstly, the power button has gone faulty on my Nexus S and I am due to send it back to Samsung for repairs, so I want to get it back to factory image 4.0.4 IMM76D using the Google image and to relock the bootloader. However, when I reboot into fastboot all the keys stop working and I presume it has stopped responding and the only way to reboot is to do a battery pull. Just wondering if anyone has had this experience before and knows a solution.
By keys you mean volume and power right?
Does a computer recognize it with fastboot. Example . Fastboot devices / fastboot reboot etc?

Volume and power keys don't work while in fastboot and it isn't recognised by that. And when it powers on regularly it say No boot or recovery img. Nope, doesn't get recognised by PC and just says No devices found...
Did it work before in the same system?
Only other thing I could think of to try is download mode/Odin
It was working fine that day. I even flashed CWM on it after trying TWRP. But then suddenly the power button broke, and when I used the key combo to get into fastboot mode using the plug in to charger method it loaded fastboot and just wouldn't respond

Honor 6 H60-L02 impossible to charge the phone

Hi Guys,
1. I have upgraded my phone to OTA-EMUI 4.0_H60-L02-L12_6.2.1_6.3.1 which runs properly.
2. Afterwards, I wanted to root this phone again, which doesn't work neither with multi-tool nor TRWM.
3. After reboot the phone was going into animated Honor logo, but nothing more.
4. I tried to reinstall the original firmware using adb shell and dd. Same situation
Unluckily the phone doesn't boot normally after the reboot.
5. Pressing the power button for a while lets the phone vibrate ones and appear logo but nothing else happens.
Pressing 3 buttons lets the phone come up with the honor-logo, but nothing more.
Pressing power + vol- and connected usb cable lets the phone come up with fastboot.
When the phone is in fastboot mode my computer recognizes it as "Android Phone - Android Sooner Single ADB Interface",
but ADB doesn't show any devices. Fastboot works fine and is Unlocked. Hisuite doesn`t recognize device...search drivers but
nothing happens.
6. Unbricking the phone using fastboot (flash boot, cust, recovery and system) doesn't change anything.
Flashing the stock recovery, using a sd-card with dload folder and firmware and booting the phone with any button
combination doesn't change anything (no installer, no recovery). Flashing CWM and booting the phone with any button
combination doesn't change anything (no recovery). ADB doesn't show a device at any other point of booting.
7. Now the accu from my phone is empty and I can't charge it again, neither with USB-cable plugged to Computer nor with
standard cable plugged into a switch. I need help before playing tennis with this phoe!! :crying:
Any idea or solution how to fix all my problem?

L02/L12 - How to go back from EMUI 4.0 to EMUI 3.1
I flashed with fastboot:
fastboot devices
fastboot flash recovery RECOVERY.img
fastboot flash boot BOOT.img
fastboot flash fastboot FASTBOOT.img
from OTA-EMUI 4.0_H60-L02-L12_6.2.1_6.3.1
Afterwards the phone began to charge again.
I copied the update.app from H60_EMUI3.1_Android5.1_6.1.1 to the folder DLOAD, inserted the SD -Card,
disconnected the USB cable from your PC, pressed 3btn till the Honor logo appears
continued to press 3btn for 8 -10 seconds and the recovery process began.
Thank a lot to panamera2011
Thanks Sam Cro!
I think your answer is underrated.
Most of my bricks on the Honor 6 (H60-L12) could be restored thanks to your help!

Lenovo tab 2 A10-70 Boot looped , Unable to get into bootloader or recovery

*accidently put this in the wrong thread, if a mod could move it. thanks*
So I wanted to get rid of the chinese recovery that was on my lenova tablet and messed up along the way.
I first enabled debbuging USB on my tablet and used adb on my pc to boot my tablet into fastboot (I am unable to enter fastboot any other way).
I ran this line: "fastboot oem unlock" and then "fastboot flash recovery twrp.zip".
The TWRP version i flashed onto the recovery was a wrong version causing my tablet to go into a bootloop on restart.
I get no response from vol up+power, vol down + power, vol up+vol down+power.
I had to let my tablet battery run out since the back battery is unremovable.
The tablet shows the splash screen when it boots and restarts after about 5 seconds.
I have no idea on what to do so i turn for help here

Unlock the bootloader and reflash the latest stock ROM.

You need to get into fastboot mode to unlock the bootloader and flash a stock ROM.

my phone bootloader already is unlocked. the problem is i can't get into fastboot mode.
Have you tried powering off the phone, hold volume down, and connect the USB cable?

I have this same problem, I am a pretty technical guy. I can get into fastboot, but the flashing always fails. Having the same problem bootlooping at the android loading animation. (Not the common power button issue)
edit: I have unlocked the boot-loader as well

Bricked Huawei P9 Lite - Stuck in Boot Screen

Hello,
as the title says... I bricked my phone. In the past, I successfully installed LineageOS on my old Galaxy S3. I got a used Huawei P9 Lite recently and wanted to install a custom ROM. Here's what happened:
1. Unlocked the phone
2. Accessed Fastboot mode
3. Installed TWRP* via fastboot flash recovery file.img
4. This didn't work and I read on the web, I could try to flash revocery2 with fastboot flash recovery2 file.img
5. This didn't help either, so I decided to cancel my plan and use the manufactorer's system since the system still booted (of course, I didn't install any custom OS).
6. The phone told me on each startup it's unlocked. I didn't need the unlock anymore, so I accessed the Fastboot mode again.
7. I re-locked the system by using fastboot oem relock password.
8. The phone asked me to do confirm this action and do a factory reset
9. After this, I'm stuck at the Huawei logo and can't access Fastboot mode anymore!
When I shut down the phone, it immediately restarts itself. No chance to get into Fastboot mode again, which I did through pressing Vol- and plugging in an USB cable.
*I tried several versions, 3.0.1 and 3.2.1 since no version worked
This may be a beginner's fault, my last phone was already unlocked and I had not a single problem back then. But this time... I hope you can help me.
What would happen if I let drain the battery down to 0% - the phone wouldn't restart of course. If I press Vol- and plug it in, would I come back to Fastboot mode or would it stay in this loop?
Any help is appreciated!
