my device axon7 2017G.

If you never connected the A7 to your computer and sent the fastboot command "fastboot oem unlock" to your device, it's still locked.
Additionally, when you reboot into bootloader, it'll display the lock status on the screen.

Hello i rooted My device with the axon7 root tutorial, ADB reboot edl and axon7root.exe and so on.
After that method is the bootloader locked or unlocked?
If i reboot in fastboot modus, there is only a zte Android sign, nothing lock status in screen.

Rooting with axon7root.exe does not unlock your bootloader. If you never followed this guide (http://forum.xda-developers.com/axon-7/how-to/guide-how-to-unlock-bootloader-stay-t3461165) or never sent the fastboot command "fastboot oem unlock" to your device, you're still locked.

Root, Downgrade and install TWRP

For the last week I have been trying to root and install TWRP on my Huawei p8 Lite ALE21. Sofar every attempt has failed.
Steps taken:
Get Bootloader Code
Unlock bootloader with "fastboot oem unlock"
Flash TWRP with "fastboot flash recovery recovery.img"
Result:
When booting into recovery the default "Huawei eRecovery" opens, not TWRP
No app can detect root
Additional info:
TWRP form here: http://forum.xda-developers.com/p8lite/development/testing-twrp-2-8-7-x-huawei-p8lite-qcom-t3187758
Trying to debug the problem, I entered
Code:
fastboot getvar all
this returned
Code:
getvar:all FAILED (remote: Command not allowed)
Additional I have tried to downgrade to android 5.0 again, but after copying the Firmware to the "dload" folder and holding the Volume-Up and Down and Power buttons, the phone wouldn't do anything but show the huawei logo and turn off.
Any help would be very appreciated!
Thank you in advance,
Oisin

The phone reboots, shows the HUAWEI logo and then turn off again.

Sorry, i didn't read the post linked.
You need twrp 3.0.2 for B5xx, i was thinking you had the right one (2.8.7 works on kk and maybe lollipop), so here you are: http://forum.xda-developers.com/p8lite/general/twrp-3-0-0-0-p8-lite-kirin-t3343320

Motorola g5 plus xt1680 has dead

hello friends I have the motorola g5 plus xt1680 by telcel. I have the bootloader blocked and I also have many files in memory that I do not want to lose.
I got a security patch which I downloaded and installed correctly, after updating my mistake I let the cell phone completely discharge, reaching the battery at 0%, after this I can not turn on the device stays in the motorola logo.
I have already tried to flash firmwares using adb but I can not mark me error, errors similar to this one:
fastboot flash partition gpt.bin
target reported max download size of 534773760 bytes
sending 'partition' (45 KB)...
OKAY [ -0.000s]
writing 'partition'...
(bootloader) Validating 'gpt.default.xml'
(bootloader) Security version downgrade
(bootloader) Image primary_gpt failed validation
(bootloader) Preflash validation failed
(bootloader) Cancelling
gpt.default.xml
FAILED (remote failure)
finished. total time: 0.066s
for more than download firmware images, all of them make me the same error and I can not find the solution on the internet.
I have been several days and can not find a solution, it is very important not to lose my files that I have on my cell phone.
Would any of you help me please?

Have u tried using the Moto Smart Assist to reflash the phone? It should automatically detect the correct firmware for you.
But if you want to flash one of the firmwares you have, leave out the "fastboot flash partition gpt.bin" and "fastboot flash bootloader bootloader.img" commands and the flash should work fine. Apparently the update you took updated the partition tables on your device so you either have to flash without downgrading or flash using the exact firmware that the gpt.bin file is using.
If you need to get your files off first, download TWRP here, and then copy it into the directory where you have fastboot and run
"fastboot flash recovery twrp-3.2.3-1-potter.img" and then scroll down with the vol keys until you get reboot to recovery. (If it doesn't flash correctly you may have to push vol key down to reboot bootloader and try flash again) After inside TWRP, you should be able to use your password to decrypt your data and then use a USB cable to get your things off the phone or take a TWRP backup of your data / internal storage partitions and restore those after a fresh flash.

thanks, I had already tried to revive my phone with moto smart assist but the software tells me that my phone is not compatible.
I can install twrp if I have the bootloader blocked or I need to open the bootloader to use twrp? but when I open the bootloader my phone restarts from the factory that will erase all my files
I think I've already got the most recent security patch that is updated, apparently this is:
https://mega.nz/#!jxUEXazJ!TVU8n458ZZwd5TfP12I_uEvslYgGc5vakyUaOeSqMOs
can I install that version on my cellphone without any risk ?
then I can flash it without losing my data by omitting the command fastboot erase userdata or is it more advisable to use the ocpion of twrp to recover my data as you explain my friend?
Thank you very much for the help

Well, if the bootloader is locked, then you can't flash TWRP until you unlock it, which you can't do because you can't get into the system to enable OEM unlocking from developer options. So you're pretty limited to what you can do...
I believe fastboot flashing everything using the exact same firmware as your most recent update, but omitting the gpt.bin, bootloader, and userdata commands would work.

I tried to flash the last ota for the motorola g5 plus and now I can install almost everything but when it comes time to flash the following commands it marks me error:

Why don't use ADB pull command to pull the data from device and run the all command of flashing except bootloader and gpt.

I think the problem is he can't get past bootloader so no ADB commands for him to have access to, and his bootloader is locked and since his system won't boot he can't turn on OEM unlocking to unlock it to flash TWRP or something similar to give him ADB commands.

Your problems are not related to the errors for "customize" and "clogo". These entries are for customazions made by Moto Maker and it's normal that they fail if you don't have any of these.
If your device doesn't boot you may have downgraded your bootloader in the past.

I have already tried to omit the bootloader and gpt commands, and I still have the same problems only in that part of the code, having the bootloader blocked limits me a lot, I do not know if I have to wait for the firmware of my phone company Telcel to flash it by adb and see if only so I retrieve the phone.
I do not know what else to try if there is any other solution

If you have the most recent firmware you don't need to omit the bootloader and gpt commands, and the clogo and customize commands almost always fail, you don't even really need them.
If it's still not booting I'm not sure what else to tell you to try. Someone in another one of my posts suggested trying to boot with "fastboot boot boot.img" and then possibly you could switch on OEM unlocking from the developer options, then reboot, unlock bootloader, and flash again or flash TWRP and use recovery to recover from there.
But I'm not guaranteeing that will do anything other than be stuck at boot logo.

[SOLVED]Stuck in Fastboot

I was on MIUI Global 12.0.2 Stable. I tried to flash Pig's latest Lineage (2020.07.21) from TWRP. The flash failed with an "Error 7". When I tried to reboot, the device went to "fastboot" mode.
After that, every attempt of a reboot ended in fastboot mode. So I tried to flash TWRP.img. Flashing went OK. But "fastboot boot twrp.img" gave the error "FAILED (remote: Failed to load/authenticate boot image: Load Error)". The result was same with "fastboot oem reboot-recovery" command.
So I was stuck in fastboot mode with the risk of battery depletion. Below is the commands I ran to flash the TWRP.
C:\adb>fastboot flash recovery twrp.img

SOLUTION: One needs to flash the fastboot ROM in MiFlash.
My situation had an extra issue as there were no fastboot ROM for MIUI Global 12.0.2. So, I downloaded MIUI 11.0.5 Global Fastboot ROM and flashed it. One needs to keep in mind about the "Anti-Rollback Protection" (https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/) and take necessary steps to avoid an anti-rollback brick.
If anti-rollback compatible ROM not available, then just delete first lines in all .bat files (.bat for Windows; .sh for Linux) up to the first line that starts with "fastboot %* getvar product..." of the available fastboot ROM. Those lines are the anti-rollback check. After than you can flash it via MiFlash.

There is a Fastboot command to reboot to recovery (TWRP if you previously flashed it):
>> fastboot oem reboot-recovery

Thanks for the reply. I tried that command too, but ended with the same error.
Now, downloading the 11.0.5 Global Fastboot ROM since no 12.0.2 Fastboot available. My plan is to just delete first lines in .bat files of the ROM to avoid 'rollback protection' and flash via MiFlash before the battery goes zero. According to google, it seems flashing the full Fastboot ROM is the only solution

SOLVED
Solved. Edited the OP.

Wow, thank you so much for pointing this out!
I just had a close to two hour journey through all emotions after trying to restart my phone and suddenly ending up in a seemingly inescapable fastboot hell...
I've tried booting different recoveries, all failing with
Code:
FAILED (remote: Failed to load/authenticate boot image: Load Error)
and was already at the point of giving up getting my system back, just trying to save my data if possible. Flashing seemed to work, but
Code:
fastboot reboot recovery
just threw me back into fastboot, which I assumed to be due to the phone rejecting the flashed recoveries just as it was rejecting them when I tried to boot them directly.
When I saw this comment I wondered whether Xiaomi implemented rebooting directly to the recovery differently (as it turns out, it doesn't seem to be standardized) and
Code:
fastboot oem reboot-recovery
worked perfectly! After reflashing my ROM from TWRP I was booted back up into my system with everything intact, as if nothing has happened.

LG h918 in bootloop with only fastboot available. Help!

Hi All,
I just followed the instructions to root my h918 and then successfully updated to h91820h. I then used the TWRP app to flash twrp, and the Magisk app to update Magisk. After that I rebooted from the Magisk app, and now my phone is stuck in a bootloop. I cannot get into download mode, or recovery mode, or the system. I can get into fastboot mode by trying to go into download mode (holding the volume down and plugginto a USB port ot the laptop.
It seems that T-mobile removed any commands from fastboot that will help me. If I try to "fastboot reboot emergency", it just bootloops. If I try fastboot boot a twrp image, I get:
Code:
fastboot boot twrp-3.4.0-1-h918.img
downloading 'boot.img'...
OKAY [ 0.667s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.686s
The command "fastboot reboot bootloader" boots to fastboot. The bootloader is indeed unlocked, but it looks like I'm stuck, because the LG fastboot doesn't allow anything to fix the brick.
Code:
$ fastboot getvar unlocked
unlocked: yes
finished. total time: 0.020s
I'm not finding any hope or help on Google. It seems if I can't boot into twrp or download mode, I'm toast, and I can't figure out how to boot into anything but the bootloader.
Does anyone have any suggestions on how to bring this phone back from the dead?
Thanks,
Rob

How are you trying to boot into download mode, are you trying to do it via fastboot or the hardware buttons?

im having the same problem, i dont have download more or twrp now, all i have is fastboot

i am going to assume going into download mode through fastboot is the only option for the two people posting for help here. from what i see from the posts, both hardware buttons sequence , or the plug in & down volume are the ONLY way to get to fast boot.
and fast boot is the only thing available on the phone.
i have labeled that a soft brick .
i asume one of the two help seekers have used the magisk 20.2 trap?
the release proved to be a problem , there is a tutorial on how to fix it.
i will go look for that and try to edit it into my responce later.
for now, are the two seekers already acomplished in this procedure?

ok i found a way to get into twrp (if ever installed)
1- turn off your phone
2- hold Volume Down + Power button until you see the LG logo
3- When you see the Logo release the power button while still holding the volume down and immediately after release press power button 3 times.
4- you will see a factory reset screen, press yes twice and it will go to twrp.
