How-to Fastboot on S7 Tablet

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

Hi brother, i have one s7 here model s7-202u and i try to flash and cant boot...
Always appear on screen about fastboot mode...
And i cant boot this tablet.

Can't boot or flash to TWRP or CMW

Today I tried booting up to recovery (power+vol down), after choosing Recovery Mode from the menu and hitting Power button, it gets to a screen with the green Android guy with a red triangle and just stays there.
So I rebooted the phone. Launch Nexus Root Toolkit, I tried to install CWM or TWRP, neither works. It gets to the same recovery mode and gets stuck there, only this time, it gets stuck on the Google logo instead of the Android guy with red triangle. I even try to flash stock recovery, and it also doesn't work.
Why can't I get into CWM or TWRP nor can I flash them?
Thanks for any help.

Be sure u are bootloader unlocked.
Android guy is normal... Is a safety step before entering on stock recovery, to pass that: hold power and hit once volume +
Probably u cant flash images cuz fastboot isnt working(old fastboot.exe file), wrong recovery file,...

Bootloader was unlocked. I launched the CMD Prompt from Nexus Root Toolkit and ran the fastboot command to manually flash the downloaded CWM and it worked.
Code:
adb reboot bootloader
fastboot flash recovery recovery-clockwork-x.x.x.x-mako.img
So maybe something's odd about the simple one-click utilities in Nexus Root Toolkit that is not working.
Thanks for the help nonetheless. :good:

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.

[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
Code:

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

but can u tell me how to reboot straight to recovery while finish flash recovery in fastboot mode, i can't find way do this.
I have unlock the bootloader so each time i boot up the phone, first there is a lg logo displaying for about 2 second and then a warning msg will appear on the screen. this warning message will display on the screen for about ten second and then a lg logo appear again then boot the android system. i don't know how to interrupt the normal boot process and get into recovery manual.
when i use adb to reboot to recovery, lg recovery will appear after the warning message screen off. i turnoff the phone and press power+down button together to try to get into recovery manually, but after the lg logo appear the second time, there is no way to start recovery. the phone will boot to android directly.

Also having this problem, however when I hold the POWER+VOLUME DOWN buttons to try to boot into recovery after shutdown/battery removal - the system STILL loads.
I get the warning saying the bootloader is unlocked though. After that the phone just starts up as normal, even though I'm holding the buttons

here is the step i find finally
1. re-boot into fastboot mode
2. flash twrp use fastboot command.
3. power-off the phone
4. power-on with power and volume down button holding
5. while lg log appears, release power button immediately for 1 second and then hold again
6. when recovery selection screen appears, select 'yes' both two times.
now phone boot to twrp recovery.
REMEMBER: WHEN YOU BOOT INTO LG'S SYSTEM AGAIN, YOU WILL LOST TWRP. IF U WANT TO USE TWRP AGAIN, U MUST RE-FLASH TWRP AND REPEAT THE STEPS ABOVE. THIS WILL LOST ALL DATA(PHONE WILL GET FACTORY RECOVERED)!!
I hope this can help you, good luck.

You need to delete the file recovery-from-boot.p in /system
Each time you boot, that file gets executed and restores the stock recovery from recoverybak. Alternatively, you can flash TWRP to both recovery and recoverybak.
