Update to latest ADB and Fastboot from here:
https://developer.android.com/studio#command-tools
The ones that come with Minimal ADB and Fastboot are incompatible/obsolete.

[Completed] Moto G2 UTAG Flashfail Configured As Fastboot

Hi
I tried to root my Moto G2 running android 5.0.2 following a tutorial I found on technoprotocol.com (can't post link as I am new to forum.)
I booted into fastboot mode as per the instructions (after enabling usb debugging) and tried to root. Unfortunately I got an error (I didn't catch what it said) and now my phone only boots into fastboot and I can't go into any of the sub-menus ("recovery", "factory" etc.)
I downloaded minimal adb and fastboot and tried the command:
Code:
fastboot oem fb_mode_clear
However it still boots into fastboot and wont let me go into submenus or boot into android.
Any help wold be greatly appreciated.
It now seems to be working after I ran these commands through ADB FastBoot.
Code:
fastboot erase userdata
and
Code:
fastboot reboot

idol 3 twrp question

ok reading other threads i see others having issues with flashing twrp also.
i followed the unlock procedure and it was a sucess.
procedure:
in command prompt with files in directory
1: adb reboot-bootloader
2: fastboot -i 0x1bbb oem unlock
3: fastboot -i 0x1bbb oem device-info (bootloader confirmed unlocked)
4: fastboot -i 0x1bbb reboot
5: let deviice reboot
6: adb reboot-bootloader
7: got files from here http://forum.xda-developers.com/idol-3/general/twrp-custom-recovery-idol3-6045-t3162608
8: fastboot -i 0x1bbb flash recovery twrp-2.8.7.0-idol3.img
10: rebooted
11: scratched head as default recovery booted.
so i am assuming i need to apply root before flashing custom recovery?
thanks in advance for any help provided.
I'm not sure there is any difference between the 5.5" & the 4.7" in term of the procedure but here's what I did on my 5.5"
1. Get ADB SDK application installed on PC
2. Download and install the correct USB driver for the phone. Assume you already downloaded the custom TWRP recovery image
3. Enable USB debugging mode on the phone
4. Plugin the phone to the PC, open Command Prompt
a. adb devices // to make sure the phone is recognized and listed
b. adb reboot bootloader
c. fastboot -i 0x1bbb flash recovery twrp-2.8.7.0-idol3.img // browse to where the .img is located first
Should be it!
You can root it AFTER install the custom recovery.
Hope that help!

I had to use Flashify to get it to stick on my 60450. Otherwise, I would have to use commands to get it to boot into TWRP rather than stock.
5.5" cricket here.
it boots into twrp till it loads the os wich seems to repair the recovery.
be annoying if it is self repaiiring.
ok root applied.
how do i flashify twrp.

OEM unlock not appearing in developer options.

I cant seem to find the unlock OEM option at all in the developer options. I tried to add images to show my problems but was not allowed to....sigh. Either way I cannot see the OEM option in my phone.

This is what I get after flashing TWRP with no issues and trying to reboot into recovery.

Yes I did. I can't seem to figure out what to do next. It shows to me that the twrp recovery has been installed but when i go to it it comes up with the recovery from the huawei. So i can't flash anything.
So if it doesn't have the OEM option to unlock can I not install recovery or root the handset?
Without the phone plugged,hold volume up and power till u see the logo, release power while keeping volume up pressed.
try this
shut down phone
press vol up + power
when saw the huawei logo
release all buttons
wait
done
u r in twrp

fastboot boot is not supported. try the keys combination
Fastboot boot twrp.img would not flash twrp, what it tries is downloading twrp.img then boot it without flashing.
I'm not sure how it is for the Chinese Mate 9s, but you'd want 'fastboot flash recovery twrp.img', that flashes twrp (if your twrp is named twrp.img).
If it says it flashed twrp, try 'adb reboot recovery'.
Never flash recovery to boot partition.
For recovery : "fastboot flash recovery twrp.img"

Are you using "fastboot flash recovery twrp.img" or "fastboot boot twrp.img"? The boot command is not allowed.

I'm still trying to unlock the bootloader using the command prompt and ADB and Fastboot, after I got the Huawei code:
Step-1: Open the command prompt and enter the following command.
Adb reboot bootloader
Step-2: Your phone will reboot and enter into bootloader mode.
Step-3: Now enter the following command to finally unlock the bootloader.
Fastboot oem unlock xxxxxxxxxxxxxxxxxxxx
And it always fails.
I do not know how to use "fastboot flash recovery twrp.img" or "fastboot boot twrp.img".
Do you have a guide how should I do it?

But he says it fails every time.
@tigrelouco
Open a terminal or adb shell and enter these commands:
getprop sys.oem_unlock_allowed
getprop ro.oem_unlock_supported
And post results.
Found this in another thread:
tohc1 said:
To answer my own problem/ for anyone else having problems it is necessary to remove the factory reset protection (frp) to do this you need to remove all pin/password/fingerprint locks, then remove all google accounts and finally do a factory reset.
Then the usual adb/fastboot commands work fine.
As linux33it says the bootloader can be unlocked without the option in the developer options.

Download Terminal emulator from the playstore or use adb from command prompt.
By the way, you dont happen to use Linux?

[RECOVERY][TWRP][Unofficial][Port][ROOT] Ulefone T1

This is a ported TWRP that I put together from another MTK6757 recovery that was twrp ready. I have only used it so far to root my device. I am not responsible for any harm to your device.
1) Backup your phone.
2) Unlock Bootloader (!! YOU ARE WIPING EVERYTHING ON YOUR PHONE !!)
3) fastboot boot recovery-20170912-t1-twrp
4) Swipe modify system partition
5) Install desired root method (I installed Magisk here.)
6) You phone will be back to factory, with root installed.
Enjoy!
Succeeded
Thank you ^ ^
Open CMD (command prompt) and type the next command :
adb reboot bootloader (and press enter)
Now type the next command :
fastboot boot c:\adb\recovery.img (and press enter)
**I installed Magisk but magisk hide not wroking!!! **Why??

I only just got my T1 and this is my first time using it but under "Developer options" in settings of the device there is an option for "OEM unlocking". Googling that the first result says "OEM Unlock is a protective in Android Lollipop and later that is usually a step that users need to enable in order to officially unlock the bootloader of their device." Hopefully that helped.

Hello, I installed magisk and It works... But with this method "fastboot boot c:\adb\recovery.img (and press enter)" recovery is on PC and If I try "adb reboot recovery" the phone reboot on a black display and after I reboot in normal mode !!!.
And of course, the power+ vol up doesn't work.
Wonder when they will actually create a thread for this phone.

Did this work for you and have you had any issues with your device at all? This is my first MTK device so I want to make sure it's all good. Seems almost too easy compared to rooting and unlocking my Xiaomi devices
When I enter the cmd fastboot reboot bootloader, all I get when the phone reboots is "bootloader mode...." in the lower left corner. When I type fastboot oem unlock all I get it "waiting for device"
