[Completed] T-Mobile lg v20 becomes un-visible when put into bootloader mode. - XDA Assist

I can't add any comments on XDA forum where this wuestion belongs because I don't have 10 or more comments posted instructions other than programming and ROMs. however I did post it on the XDA assist forum but i was sent to check out a forum that had nothing to do with my problem. I have the correct drivers I have everything I need to have and as soon as I put my phone into the bootloader mode for some reason the computer cannot recognize it anymore. on the command prompt I type in ADB devices and nothing shows up however, before I put my phone into bootloader mode when I type in ADB devices my phone shows up. apparently this is a phenomenon that only happens to 3% of the people that try to flash this device. I'm not the only one apparently.

[Completed] [Q] Fastboot doesn't recognize moto g 4g on linux

I have a Moto G 4g. ADB recognizes the cell and I can restart it in fastboot mode, but when I check in the terminal with:
Code:
fastboot devices
Nothing appears, and if I go on with
Code:
fastboot oem get_unlock_data
It gets stuck at
Code:
< waiting for device >
I tried as a user and as root on an Archlinux machine with android-udev rules as shown in the Archlinux wiki (sorry, i can't put the link). AP Fastboot fast boot menu shows that the cell is locked.
Hi,
You can try a different cable, or USB port on the pc...or even a different pc. Until fastboot devices detects your device, there's nothing you can do.
Reinstall drivers...and you are on the bootloader mode right?
If none of that helps, you can ask in your device section for help....

Good luck!

[Completed] fastboot will not recognise device (HTC One M7)

I've been trying to solve this for a while now and cant seem to get it to work.
I have adb and fastboot installed on the computer.
When I run the cmd window, I can get a recognition from adb when I'm in recovery mode, but as soon as I run <adb reboot bootloader> the phone goes into bootloader, disconnects temporarily from the computer and reconnects.
When I go into devices on the computer I can see that the computer see's it. It recognizes it as my HTC although it shouldn't right?
When I come back to my cmd window I try to run fastboot commands with no success. <fastboot devices> gives me a blank line and its ready for the next command.
I looked around and saw that a lot of people dint have the right cables, drivers for the phone or dint restart they're computer.
I have done it all. I re-downloaded the drivers I think 10 times in vane.
Any help would be appreciated thx
OS on phone is no longer there I lost it. dont know how.
OS on computer is windows 10 64 bit

[Completed] How to unbrick Xperia S lt26i [not a noob]

I have a Xperia S running cm 12.1 with unlocked bootloaders TWRP installed and i tried to partition my SD card [http://forum.xda-developers.com/showthread.php?t=2584759] but clearly something went wrong and now the phone wont boot. I made a lot of research and tried everything but all the guides require to be able to boot into flashmode . My phone is dead the only sign of life is a red led when its charging which after some hours of charge will shut off. When the light is off and the phone connected on PC, the PC can recognize the device on unspecified devices (QHSUSB_DLOAD). i have installed all the needed drivers from Sony, google drivers from sdk, and adb drivers(adb wont see the device and i tried everything to do so, but nothing seem to work). I got a market for android on my pc called mobogenie that when i connect the phone it detects that a phone is connected but wont see what phone.The hardware reset buttons work but its useless in the current position. Concluding, the phone is bricked and wont open in fastboot-flashboot-bootloader-TWRP, its recognized as a device but not as "Xperia s" i got all the drivers and i want to flash the original firmware (already downloaded) to fix it. A possible problem is that the partition table is destroyed and after the flash it will hopefully be restored. The problem is not on the hardware but on software. I tried to trigger the download mode with the Samsung way (USB jig, 300k ohm ) but nothing happened as expected. Every solution i found required flash mode which is not accessible at the moment and i tried lots of things to go into fastboot(ever the rubber band trick,remove the battery etc). PLEASE help i dont know what to do, please help me flash it (i already got flashtool, Emma) or anohter solution. Thanks for the help in advance. (its my first thread in the forum, i hope to post it on the right section, i posted it here because i need the assistance of the developers i guess)

[Completed] Oneplus One bootloop with Linux

Apologies if something similar has already been posted on here already. I have had a look, but can't seem to find anything.
I was trying to root my oneplus one this evening, and was following a very useful link here....
https://forums.oneplus.net/threads/like-a-boss-how-to-root-your-oneplus-one.58493/
....and got to the bit that says "sudo fastboot oem unlock" - waited a minute, and the phone rebooted showing the android and 1+ logo. But before anything else happens it turns itself off, then back on again. And continues to do this indefinitely. I can get it into fastboot mode, but not recovery. When it is in fastboot mode the pc doesn't recognise it. Something obviously isn't right, but I'm not sure what. I'm guessing something is possibly corrupt.
What I think I need to do is firstly, get the pc to recognise the phone somehow. Secondly, install a recovery on to it and thirdly, flash a rom. I've been scratching my head all night trying to work out how to get the phone recognised, and Googling like a teenager who's just discovered porn is available on the Internet.
Is there anybody out there who is familiar with Linux who can possibly walk me through what I need to get my phone working again?
Thanks for taking the time to read this, and for any help that may be offered.

i will ask here too
is there any way to rescue my phone from this?
my phone jsut starts into fastboot as soon as it turns on, even when i plug in the charging cable, it goes into fastboot in a second
i tried the adb method, instaleld it all, used the fastboot tools for "fastboot reboot", nothing
i used fastboot continue, nothing
i tried fastboot oem unlock, not recognised
the recovery mode for factory reset is working, but since i have seen in a german forum that this is not helping and i rather not loose my data because of the 2fa apps, i wont do that just now
i tried it all now but absolutely nothing works
i didnt enable the developer options in the 4 years i have that phone now, and i cant unlock it, even tho i got the unlock.bin from LG and everything
is there any solution? or is this phone now bricked and i can throw it against a wall out of frustration?
I have same problem, any someone can help me???
