Hi guys,
I had bootloop issues so tried couple of methods to solve it but could not.
I was able to connect it to my PC and in command window i tried fastboot erase recovery, fastboot erase system, fastboot erase cache. but this did not work and now after i press power button and volume button and select recovery mode, it gets stuck there itself. Also i cannot find my device when i type adb devices in command window.
Please help me :crying:

Try typing fastboot devices instead and in bootloader mode try flashing the stock angler images such as system, boot, etc.

I followed official Ubuntu Touch instructions for installing/uninstalling Ubuntu.
Installation went without any problems, but after returning back Android, the device is stuck on the "X" animation and cannot proceed.
I tried the following:
Going into recovering mode
Flashing the device to stock version of Android (v4.2)
Flashing the device to previous installed Android (v4.3)
The flash-all.sh command is executed successfully every time, but boot gets stuck at "X" animation no matter what I do.
What can I do to fix this issue? Any ideas?
Thanks!

try to format cache via fastboot.
fastboot erase cache and fastboot format cache and reboot!
if it happens the same try to enter in the stock recovery! attention just stock recovery and press and follow this:
---> Note that some users indicate that they can't get past the X on boot. If this happens to you, reboot into the bootloader and select recovery. Then, when you see the Android with the red exclamation mark, hold power and press volume up to take you to the menu. Wipe cache. If that still doesn't work, boot back into recovery and do a factory reset (this will obviously delete all your data & files in /sdcard...).
and if not boots dont worry try to flash everything again manually dont press the button flash all , just follow the point D
D. Type in the commands into the command prompt
1) Make sure your computer recognizes your device by typing: fastboot devices
2) Unlock your bootloader (if you have not already done so): fastboot oem unlock
3) You will see a prompt on your device. This will wipe your entire device (including the /sdcard folder). Accept. Note: you use the volume keys to change the option and the power button to accept. You cannot use the touch screen.
4) Reboot by typing: fastboot reboot-bootloader
5) Flash the bootloader: fastboot flash bootloader bootloader-mako-makoz10o.img (or whatever the name of the bootloader image that you downloaded).
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.48.img (or whatever the name is of the radio image that you downloaded).
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system system.img
10) Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
11) Flash the kernel/ramdisk: fastboot flash boot boot.img
12) Flash the recovery partition: fastboot flash recovery recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== the second option seems to work better for most people. Thanks joostburg.
14) Reboot: fastboot reboot
15) Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the Dalvik cache.
it should works!!
Thanks a lot for your answer Alvin - the issue was related to caches. I managed to fix the situation by doing the following:
Going into the bootloader mode and selecting "Recovery"
Holding volume up and power button until a new screen is opened
Do a factory reset
Wipe out partition cache
Do a factory reset again
Everything seems to be working properly now.
I have the wt86047(HM2014813,HM2XTDPro) and I have dead emmc on my phone. The internal /data /system and /cache partitions are unmountable. So I decided that I try to boot from sdcard.
I have used this tutorial Dual boot to partition my sdcard and modify the recovery and the rom(Lineage 14.1) to look for the system, data and cache partitions on sdcard.
But when I try to boot up the phone is stuck at the MI logo and I see my device in fastboot. To be able to boot to my device I need in fastboot to execute fastboot boot modifiedboot.img. This is not too much convenient as I need pc to turn my phone on. I also can only boot recovery and not to get to the recovery mode. I can however flash the image to the /recovery partition. I suspect that my /boot partition is also corrupted. I tried to manualy flash boot also with no succes. Any ideas how to boot the phone without need to use fastboot?
I have the exact same issue with the same phone.
You have modified only the fstab file ?

In boot.img yes(fstab.qcom), in TWRP the etc/recovery.fstab and in the updater script any mention of /system and /data.
The phone boots with the fastboot boot, but it is quite slow as I have quite cheap sd card in it. I would buy a better one If I would be able to boot the phone without computer.
EDIT: Camera is also not working for some reason
Try folding the fastboot ROM.
Same thing happened to me. I tried and flashed the fastboot image. It worked. This happened to me a long time ago. Don't worry about bootloader if you can see the fastboot screen with the mi man on your phone .

This won't help. This is the hardware issue. The storage chip on the motherboard is dead. You can not write anything to it. It is possible to replace that chip but it is a quite difficult operation.

I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)
Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

Yeah, so I wanted to flash TWRP but it doesen't seem to work i did what was said in many guides but maybe if you tell me how to do it, it will work =) Thanks
So i tried to flash TWRP with the TOOL ALL IN ONE, everything was okey but then error happened called "Unknown device"
First of all, which version of G6 do you have? The US997 one, or the H870?

H870
For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.
The screen on my Stock unrooted & locked Nexus 6P is completely non-functional (shattered, not displaying anything, likely not responding to touch) and I'd like to wipe it before disposing of it.
I'm able to blindly navigate to the bootloader but I'm having trouble unlocking for the purposes of
Code:
fastboot erase system -w
.
Process
Boot into bootloader then issue the unlock command:
Code:
fastboot flashing unlock
Because I can't see the screen, I'm assuming pressing up or down will select 'Yes' and power will confirm it.
Either way (up+pwr or down+pwr or just pwr) the phone restarts and I let it sit for a while.
I reboot into the bootloader but the unlocked variable returns no.
I figured the closest analog would be to reflash via
Code:
fastboot -w update "image.zip"
, which will wipe userdata and cache - is that sufficient?
Don't worry....just download and install Nexus toolkit or do it manually by downloading Adb fastboot minimal <10mb size.
First, install driver for flashing firmware.
Reboot to bootloader,
Connect to pc,it will make sound if connected.
Now,put system.img to adb minial folder.
Right click and open cmd in adb minimal folder.
Type adb fastboot flash system system.img
Then,in the middle disconnect from pc.since,it will corrupt your system file.Do this for 2-3 times,that is flashing system.img and disconnecting in the middle to insure that system file have corrupted.
Then,at last flash system.img till end to complete.
Voila...you will have a factory reset phone.
I did this trick before selling my galaxy s5 broken display phone.
When buyer put display in front of me,it was factory reset.

Excellent excellent excellent advice - much appreciated.
You need to have USB debugging enabled btw to unlock your phone and issue those fastboot commands.
Last week i received a notification the 8.1 Oreo update was available for my Moto g4 Plus.
Downloaded the package and hit the install button. My moto restarted in order to perform the installation.
However, since i had TWRP installed and thus bootloader unlocked, the phone restarted in recovery mode.
Downloaded a TWRP 8.1 rom and installed it without a problem.
Unfotunately everytime I restart my Moto it starts up in fastboot mode.
Bootloader log shows: Fastboot Reason: reboot mode set to fastboot
From bootloader I can start the Android OS, but i wan't to get rid of this reboot mode
I tried tools like "Android Multi Tool" and "Free ReiBoot for Android" but this reboot mode can not be cleared.
Anyone encountered this problem and how did you fix it.
Thanks in advance
Try this:
Reboot your device to the bootloader.
Connect your device to your computer and open an ADB terminal on your computer.
In the ADB terminal, type 'fastboot devices' without quotes. Press Enter - your device should respond with its serial number.
If so, then type 'fastboot oem fb_mode_clear' without quotes. Press Enter, then reboot your device.
That fb_mode_clear command seems to clear a flag that keeps your device booting into fastboot (usually for OTA updates).
I have Tried that option as i found it as one of the possible solutions for this issue.
the clear_fb unfortunately does not remove the fastboot mode on my moto.
