How-to Fastboot on S7 Tablet - Ideos S7 General

Alright, fastboot is useful for development but I am posting it here because it is a general topic and won't be discussing developing.
fastboot is useful because you can test kernel builds without having to worry about it not booting, if it doesn't you just remove battery and it boots normal.
While device is off, hold both volume keys(up and down) and power, keep it held until the device goes black but lit screen. This is the bootloader screen and lets you run fastboot commands.
Another way is to have a rooted S7 and in terminal do the following:
su
reboot recovery (you could do adb reboot recovery from your pc without using terminal on device)

I think razor knows because he mentioned this elsewhere, but in case anyone sees this and tries reboot recovery...
Fastboot is actually
adb reboot bootloader
reboot recovery enters recovery and results in a factory reset

Please tell me more about

Trouble flashing 5.0.0! Help needed!!!

Need help here!
My Nexus 10 was with stock 4.4.4, rooted with TWRP. I decided to flash the factory image files by removing the -w in flash-all.sh. However it ended up with being stuck with the rotating balls. After about 45 minutes, I decided to go to the fastboot mode (pwr+both volumes), then select recovery (I planned to do factory reset and clear cache). After trying to reboot into recovery mode (pwr + one volume button), it now shows an open bootloader with following message below the bootloader (the bootloader seems still unlocked):
Dowloading...
Do not turn off target!!
What does it mean? What is it exactly downloading? And what should I do? Should I lock the bootloader? Also it does not respond now if I push the volume buttons. It's not recognized on my Mac with the with the following command:
fastboot devices
I also notice the following line:
Reboot Mode Flag: NONE
Now I just booted into recovery, but it shows the bootloader with the exclamation mark! After a few minutes, it automatically switched to the never-ending rotating balls. What can I do?
When you get the Downloading...message you're in the Recovery screen. Don't worry about the message. Press vol up and power to get into the recovery menu - there you can wipe cache and system. As you're in recovery, Fastboot devices will not recognise your tablet, only adb commands.
If I was you and this didn't work, I'd just reboot into fastboot and flash the image files manually. You'll lose root, data and twrp but these can easily be gotten back through fastboot.

Non-rooted OP2 turns on by itself and stuck in recovery mode

Hello all,
Just a heads up that I have little to no knowledge of modding/rooting phones whatsoever.
My phone decided to reboot by itself earlier today and was stuck in a boot loop for around 30 minutes before I managed to get into recovery mode. At this point it is still boot looping. Afterwards it just stop the boot loop and now stuck on recovery mode. Powering it off from recovery mode or by holding power button for 10s will only results in the phone rebooting itself into recovery mode again. I can get into Fastboot mode, however. Wiping cache and rebooting does not seem to do the trick as it would only go back to recovery screen after the OnePlus logo again.
Please advise on this matter
install drivers. connect to fastboot. Type "fastboot continue", this should turn on your phone but it's a temporary fix. Once it's on copy your data & perform a factory reset. - found it on oneplus forums (haven't tested by me)

Thanks for your reply, where exactly do i type "fastboot continue" ?
> First you need to install ADB & Fastboot to your Computer (Use This guide)
> Then Install Oneplus 2 Drivers (Use This Guide)
> Connect phone via Fastboot mode (Turn off the phone. Hold Volume Up + Power to enter fastboot mode. Connect phone to pc)
On the first guide (ADB & Fastboot) you'll find how to open a Command Window to issue fastboot commands. That's where you need to type "fastboot continue"

[SOLVED] Xiaomi Redmi 4 Prime cannot boot to TWRP

I have a Xiaomi Redmi 4 Prime/Pro and my problem is that I cannot boot into recovery using the Power+Volume Up method. When I do so, my phone gets stuck at the Mi boot logo. However, I can boot into recovery when I hold Power+Volume Down (I enter fastboot mode), then I connect my phone to my PC and I use the commands:
Code:
fastboot flash recovery twrp.img
fastboot boot twrp.img
I don't know if it's normal that my phone restarts automatically and boots into recovery when I hit enter with the last command.
I want to be able to get into recovery using the Power+Volume Up technique. Also, I heard that if I hold the Volume Up key when I reboot from fastboot will open a window with an option to disable stock recovery replacement. This also doesn't work and gets me to the stuck screen with the Mi boot logo.
Is there anything I can do to open TWRP using the Power+Volume Up method?

Switch off the phone and wait for 10sec. After that hold together Volume Up + Volume Down + Power and wait (i guess 5-15sec) until you see recovery.

Thank you so much! It actually works! I don't know how, because usually it worked with the Power+Volume Up method.. Anyway, thanks!

Hello,
thanks for your response. I don't know if you actually read my post, but my phone reboots after the command
Code:
fastboot boot twrp.img
and then it directly boots into TWRP. So getting into TWRP isn't that much of a problem here. I wanted to get into recovery without a PC and without using any of these commands.
Also, please try to describe the procedure more precisely next time because typing out just one command that isn't even surrounded in

Thank you.

Hello,
thank you for your answer. One thing I forgot to mention is that I use a custom OS too (MoKee ROM) with Android 6.0.1. Although this has an option for 'Advanced reboot' where you can reboot to recovery, this option always got me to the Mi boot logo and stays stuck there.
Also, I already fixed this problem by holding Power+Volume Up+Volume Down at the same time.
Best regards,
DJsushi

Problems booting into recovery

Okay, to start with, I've read the other threads about this. I understand the process that *should* work:
1. Power off.
2. Then, press and hold both all Volume Down + Power buttons at the same time until the LG Logo is being displayed on your LG V20.
3. Now, release the keys and press the above combination again however, this time you should wait until recovery mode menu is displayed.
...and I've tried the version where you keep holding the Volume Down button the entire time.
So, yes, I've reached the white screen where it asks you if you want to do a factory reset. I've hit "Yes" to both questions. The problem is that it really does a factory reset then.
---
After unlocking the bootloader, I installed TWRP via fastboot:
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
...everything went fine.
But I can't get into recovery. And since I'm waiting to have TWRP working so that I can flash root, I can't boot into recovery via an app.
What did I do wrong?
EDIT:
Okay, it looks like TWRP isn't working properly. I tried "adb reboot recovery" and that got me to a dead Android icon and a "No command" message. I have no idea why TWRP isn't working.

to confirm, have you verified you are using the correct TWRP version for your V20?
in this step "fastboot flash recovery twrp.img" is your twrp image that you saved, named twrp.img? If its not, that command won't work correctly.
usually after I flash recovery, when still in the recovery menu, i choose reboot recovery just to make sure it did stick. If it reboots back to itself, then try rebooting the device, and again confirm with manually entering recovery. Maybe overkill but it works for me LOL.
Good luck!
I am in need of big help! I made a critical error after days of trying to navigate the minefields of rooting my device. I have a LG V20 h910 and it is no one-click wonder root. It made me work for it and I finally got it. I loaded LineageOS 14.1 and all was good until the USB OTG cable from my PS4 controller did not register anymore. Damn, that was a let down, and probably led to my careless move of needing to downgrade my TWRP, saw the version I needed, forgot these are device specific, and now I'm stuck in a hard place.
Perhaps the fix is easy, but I have not found the answer after many, many searches...
I had TWRP 3.2.1-2 and needed to downgrade to 3.2.1-0 to try SuperRom (hoping it would have OTG ability). I hastily grabbed the first TWRP 3.2.1-0, threw it on the SD card, wiped everything except internal storage, and flashed the img, and did a reboot. Road block went up.
I tried getting back into recovery, did the PWR and DOWN pressing combo and got the Factory Reset screen, but after clicking "Yes" to both, instead of getting the TWRP screen, I got this error screen (attached).
I tried another idea - hooked it up USB to my PC and tried accessing it via adb/fastboot. I tried multiple drivers for my device, but no adb and no fastboot devices were ever found. The only thing that almost worked was booting phone into FASTBOOT mode by holding DOWN btn and plugging in a USB cable attached to PC. Once in FASTBOOT mode, My PC at least saw the ID for fastboot device. I tried to flash TWRP via fastboot, and it looked like it would happen, but in the end there was no phone screen response to my attempt, and the cmd window on my PC would get stuck and just hang.
Can someone please advise me on how I can fix this problem?

Can't flash TWRP on my Redmi Note 7

I'm quite unexperienced to these topics, however I followed every guide I found online and in this forum, but I never seem to succesfully flash the unnoficial TWRP for my Redmi Note 7. Every time that I finish the process by entering the comand fastboot flash recovery twrp.img and then holding vol+ and power, It takes me back to the original fastboot mode of my device. I already have my bootloader unlocked and the ADB drivers installed on my PC and tried almost every tutorial I found (inclouding this one: https://forum.xda-developers.com/redmi-note-7/how-to/one-redmi-note-7-unlock-bootloader-t3890751).
I don't know what to do. If any one can give me a hand on this I would be very grateful. Thanks!

Once you've installed the twrp in fastboot mode you must reboot the device by holding vol+ and power until the twrp boot up and NOT with the fastboot command.

Yes, I do that, but instead of taking me to the TWRP how it should be, it takes me back to the fastboot screen
You're sure to hold volume up and power and not volume down and power? Try to disconnect the device from the pc before reboot.
