[Q] G2 D801, PC can't see my phone (I'll you buy beer if you help me) - T-Mobile LG G2

Hello, thanks for reading.
I want to start by saying I'm not asking how to fix my phone. All I need to know is how to make my computer recognize my phone so I can give it commands via adb/fastboot. And if you can help me I'd be happy to buy you a beer!
After that I think I can figure out the rest. I've been searching threads and trying things for weeks with no avail. My problem is similar to many, but slightly different so I really do need help. My LG G2 D801 is stuck in Fastboot Mode.
But my primary problem is that my computer doesn't recognize my phone in fastboot or adb, even with Official LG G2 D801 drivers.
I'll try to briefly and clearly describe my situation and what I've tried.
Long Story Short:
1. I rooted using TowelRoot method.
2. I broke my Recovery by trying to flash TWRP using an app called Flashify.
3. I attempted OTA update in spite of my broken Recovery and bricked my phone.
4. Now my phone only shows LG logo, then goes to Fastboot. (XXX = numbers change each time)
Fastboot Screen:
"[XXX] fastboot mode started
[XXX] udc_start ()"
5. Won't boot into Recovery or Download Mode.
6. So on my PC (Windows 8.1) I first cleared all Android drivers, then installed the official LG G2 D801 drivers, and Android Studio with ADB.exe and Fastboot.exe. I also tried different usb ports and cords.
7. But my PC doesn't recognize my phone, so when I run the command "list adb devices", my phone does not appear (However, my Brother's Kindle Fire, Galaxy Note 3, and Galaxy Note 2 show so it's just me). Perhaps this means I never checked USB debugging?
8. If someone can help me I'd be happy to buy them a beer:highfive:. Thanks for reading and I appreciate any help!
9. I should also mention that I also have access to a Linux computer running Ubuntu, although I'm not very familiar with that OS.
My Device's Information:
LG-D801 running LG's stock 4.2.2.
Software version D801V11b
Build Number JDQ39B
Kernel Version 3.4.0

I think I had your similar situation. Go here: http://www.koushikdutta.com/post/universal-adb-driver
Download and install that msi, it will install a universal driver that helped my PC see my phone when no other drivers could.

[Q] Mount USB storage under ClockWorkmod Recovery 6.0.1.0

Hello,
My phone had been experiencing a host of problems, so I formatted all partitions. (/sdcard, /system, /cache, /data, /boot)
I planned on using the "mount USB storage" to transfer a copy of CM10 to the sdcard and flash that from recovery,
but the device does not appear in my computer or device manager in windows, and Linux doesn't see it either.
In it's current state, it's soft bricked, is there anything I can do to fix it?
It now says "fastboot mode - no boot or recovery IMG", and I have no drivers to communicate with it under adb or fastboot.
Thanks,
-Max
Use this guide to recover your device.
Thanks, but my issue is that I can't install the drivers, could it be a windows 8 thing?
Everything seems to require that I enter USB debugging first, which is impossible for me now.
I think the ADB driver is impossible to install, unless I can do it over CWM, and every fastboot driver I've tried has failed too.
How did you erase everything? Was it through fastboot or CWM?
I did it through CWM. I had just recently installed Windows 8, and hadn't connected it since then so no drivers are installed.

In my opinion, its safer to erase everything from fastboot.
If fastboot recognizes your phone, then you can erase or install whatever you want.
If fastboot does not recognize your phone, then you can't erase it. You then need to find out why. Bad drivers, wrong folders, bad usb cable...In the meantime you phone will still work.
On my windows 7 box, under the administrator account, it took a while to set up the drivers, don't know why, but windows would not take it at first.
Maybe you can mail the phone to a xda member to get it going again...

I am sorry to hear about your phone. You are not alone I did the exact same thing a few days ago. Don't beat yourself up I have done that enough for both of us. Through my research into this i found there a few things that you might try (I don't own a PC so I haven't yet)
To get the drivers, I read a couple people had success downloading PDANet and installing them that way. I think they are located in "legacy drivers"
From the original "root, un-root" thread for your model download the stock boot img and try to flash that using ADB
follow the instructions to un-root and start over with rooting.
I also was going to look into Wug's toolkit (in the dev section) it looks like that may be an easy option to flash a working boot and recovery img.
I hope this helps please let me know.
I gave up to quick and ordered a GNex but I'm not touching that until I get my NS4G sorted out (my faith in my abilities is shaken and I could not handle bricking a brand new phone). I will be going to a friends house tonight to use their PC and try to get my NS running. I will be back to let you known what works and what doesn't. If you try or find anything would you please post? Two heads working on this issue are better then one. Thanks and good luck.

*** success ***
The solution was an easy one thanks to our developers, the hard part was finding the answer and of course, beating myself up for making the mistake in the first place. Here's what you do...
Leave your phone with the battery out for a while. Download "Wug's Nexus Toolkit" In found it in the NS4G dev section but I believe it covers all variants (not sure which you have) at the select your model and custom JB ROM download the drivers (from the actual toolkit) turn on, plug in and select flash stock img, relock boot loader, pick the stock ROM you want and press go and your phone will be flashed and reboot in under a minute. Sign in on your phone (the toolkit should auto populate your new ROM and then just follow the steps to unlock, flash and install a custom recovery then pick any ROM you want and start over.
I really hope this helps you as I'm sure you find the whole situation as stomach-churning as I did. Please PM me and let me know.
If it does work please leave a thank you or donation to the dev for creating such an awesome tool. Again, good luck hope you get your nex back online.

The Nexus Toolkit was actually my first option, it's helped me out before. I went back and tried installing the drivers using the 3 options it gives. # 3 & #2, RAW and Samsung signed drivers don't work. Option #1, the PDAnet drivers didn't work last time I tried it (all 3 options require USB debugging enabled). However, I just tried #1 again by turning on the device in CWM and that seemed to work, but I'm not sure (installation went according to the guide). However, once I tried to flash stock img, it gave me errors about not being able to reach the device in fastboot. Can you elaborate on those two steps, driver installation and flashing? As soon as I can get fastboot to recognize my device I can pretty much take it from there. BTW, I've got a i9020A and using NRT 1.6.1; and what's the significance of leaving the phone with the battery out for a while?
Mine was in the box with the battery out overnight. When I had access to a PC and plugged it in it said something at the bottom of the fastboot screen in grey that it did not before and I actually think that was the trick (System normal or system OK or something like that and when replugged to the USB the message just repeated and stacked up on the lower left of the fastboot screen). Try letting the phone sit for a while. All driver options failed for me except the tool kit.

Tried your fix, but the phone remains unable to have it's drivers installed. It's always giving "USB device not recognized" errors no matter what I do. I'm just going to shelf it and accept my loss. Thanks for the help though!
edit: Tried using some Linux tools, much greater success! This guide finally got my device listed under fastboot: http://forum.xda-developers.com/showthread.php?t=1447040
edit2: Up and running again with the android-tools-fastboot package for Linux and a standard stock image flash: http://forum.xda-developers.com/showthread.php?t=1572307
I am so glad to hear it! I stayed subscribed to the nexus s forum just to keep up on your progress and to try and help. Good for you.

[Q] LG-P506 Fastboot Can See My Device But Won't Show The Serial Number

So I have a LG p506 and I recently installed cyanogen-mod 10.1 on it. I had to use the November release as the newest one wouldn't load past the cyanogen logo(i let it run for a couple hours). Everything seemed to work great after that. So I put the phone in my backpack for a later date.
When i finally pull it back out the battery was completely dead, and plugging the phone into usb would not charge it. I used an external device to charge it.
Basically the only thing the phone can do now is load the lg logo, go into emergency mode, and fastboot. I can erase and flash images, I have tried system boot and recovery multiple times with different files.
However I get the same two things every time i try something:
1. when I plug the phone into usb, the phone will do its thing then give a STALL GET_DESCRIPTOR error
2. fastboot devices shows something but I get a "?" where the serial number should be.
I am not proficient enough with fastboot to try other commands. Any one have some advice?
Also, I've tried every usb port I have, theres only one that works with the phone. One of the usb ports shows up normally on the phone but fastboot won't show any devices. I am running windows 7 ultimate x64.
The one thing i haven't tried is reinstalling windows 8 on one of my hdd's and seeing if it isn't a win7 issue. Ive used it with win 8 before and it didn't give the error message.

fastboot doesn't show a serial number for that device. At least never has for me. If 'fastboot devices' lists something like
Code:
List of devices attached
???????? fastboot
then you're good to go.
damn that was my only thing to go on lol. nothing will get this phone to boot into recovery. im about to get a sd card reader for my pc to test and see if its bad.

You can use fastboot to flash another recovery. Rashed should have a link in the OP for the 4.1.2 ROM you said you were using. You can continue to use the command-line if you like, but I did write a Windows app for flashing recoveries. Links in my signature.

ill give it a try, but i have tried just about every recovery file i can get my hands on and no luck, also looks like winds 8 doesn't want to acknowledge my phones existence. I downloaded and installed the driver from LG but still no luck, windows 8 is giving me a failed descriptor error as well.
ok so i have been stumbling around for a bit and noticed something possible wrong.
Windows 7 device manager shows my device, installed correctly, but listed as USB Modem Phone ADB Port.
Shouldn't this be a fastboot port? Since ADB is only available via the android operating system, and i can't get into my operating system, all i have is fastboot.
I have ran thru quite a few fast boot recovery pages, and I don't know what im missing here.

I'd say that was/is the correct port name. I don't have that device anymore so I cannot say for sure.

ok, so this is a follow up on some things i have tried recently.
Since my last post i have:
1. put the sdcard into my tablet, and formatted it/ ran an error scan on it via windows.
2. i then flashed a recovery file via my phones fastboot, i pulled that card put it back in tablet to see what files it installed.
3. according to windows, flash recovery installed a .LOST folder with nothing in it, which is the same thing my tablet has on its internal memory, so i don't think there's anything wrong there.
4. phone still cant boot past LG logo(or recovery), or charge the battery when plugged in.
5. I still get a stall get_descriptor error when connected via usb, and commands such as fastboot reboot don't work, tho the phone will say its rebooting (it says its rebooting then just sits there and does nothing, command prompt will say action completed).
6. one thing i have tried as well, is telling windows not to automatically install drivers, then uninstalling my phone from device manager.
Whats interesting about this was that windows was installing its own ADB modem driver from it's own library every time i plugged in the phone. After disabling auto drivers, and reinstalling my LG drivers, the phone simply remains an unknown device.
Some things I have tried include pointing windows to the driver folder, both the downloaded folder and the folder windows installed it to. Neither worked.
The next thing I tried is the have disc option on both. Although there are setup information files in the install folder (about 50 of em), pointing the phone to each file one at a time did not work.
What did work, interesting enough was pointing the phone to a set of Naked Drivers I downloaded, although none of those drivers are specifically for my phone, and they only gave me the same problem I had when i had windows auto installing its own driver.

[Help] Google Nexus 5 might be bricked

Heya. First things first:
My Google Nexus 5 is quite... Well bricked.
I've updated CarbonROM a couple of hours ago and since then the phone's been stuck on the Google Logo, as well as starting automatically after shutting it down.
Here's some specifications:
Recovery: ClockworkMod Recovery v6.0.4.5
ROM: Carbon. The version I updated to was CARBON-KK-NIGHTLY-20140706-0428-hammerhead (Edit: For a strange reason, it didn't update to the latest version available.)
I've tried performing:
Reinstall of the same Rom
Factory reset
Following the many unbricking tutorials that require the computer to actually recognize the phone yet no "Nexus 5" appears... Actually nothing appears in devices other than my regular devices.
Phone has been already rooted (obviously) using tutorials here on XDA.
Please help :3

if no new devices appear in your device manager we cant yet do much for you. Get the phone recognised in fastboot or in recovery on any pc then restore stock rom or sideload new rom

Do you think I should get a new phone or maybe take it to a professional? I just can't get the pc to recognize it even though I have the drivers installed. (Although even if the drivers weren't installed it would still recognize it...)

The main problem in all these solutions is that the phone isn't even recognized by the computer. I'm pretty sure it's the computer's problem but you may never know. Tomorrow I'm retrieving my main rig and I'll post if that rig discovers my phone. If it does, it will make me happier than Columbus discovering America. It not, it will make my wallet really sad as I will be obliged to buy a new one.

Yup if the pc is not detecting the phone best is to try wid another usb cable and a different pc... let us knw tomorrow
Did you install those libraries properly?

This universal ADB driver + this ADB and Fastboot pack always does the trick for me.

Oneplus 6 unable to be unbricked

Hi everyone,
A couple of days ago I rooted my Op6 and then decide to flash No limits rom via recovery (blu spark), as I was used to do with my last android phone, the Samsung Galaxy Note II.
Unfortunately I missed something and now it is stuck in the bootloader screen. Nothing works from the phone and I couldn’t revive it. I use a Mac but I tried all tools that are adviced here on XDA with my friend’s Sony Vaio but without success.
I managed to update drivers but I cannot run a flash-all.bat and I cannot use MSMdownload tool.
How can I do? Thanks to anyone who will manage to help me!!
EDIT: Sorry, just noticed you say you cant use the MSM tool. This one worked for me.
You could try this
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3903272
Worked for me.
Check the guide about unbricking and if You are unable to use flash-all.bat so you Have to flash commands One by One. It's worked for me a few of months ago.
It doesn’t work either that way. I updated my drivers, but no computer is recognizing the phone.
I tried from changing usb cable or port to changing computer, to change methods.
I didn’t found any solution here on XDA, I tried everything!!
Make sure u use the cable included with the phone. Some cables doesn't work
Neither. I tried with the original and two others that I have.
if possible do you have windows? the flash-all.bat works for windows and is better to use(i was unable to use it normally in linux). What happens when you show flash.bat?
I tried Mac and Windows. On Windows it always shows in terminal "waiting for any device", even if I uploaded the drivers and made everything possible.
Did you put your OP6 into fastboot mode in correct way? I mean you might be doing the wrong procedure when entering fastboot mode.
It happened to me for the first time, I came from Samsung and I thought the phone needs to be stayed on the fastboot menu screen just like Samsung but no.
You need to turn it off and reboot it while pressing home and vol down button simultaneously until the PC recognize.
Good luck unbricking~
I always powered it on via power+volume up before connecting to the usb cable, because connecting it while powered off always resulted to power it on automatically on bootloader screen

Stuck on drivers

Hey so like i have a problem. It\s seems to be to simply impossible to get any drivers to work, i tried everything google drivers, sdk ,drivers that come on phone and drivers from some random websites. Nothing works, tried both w10 and linux ubuntu. On my older pc i had 0 issueas other than simply doing something dumb.
Im out of ideas, help? Also tried with sony z5 premium instead of my nokia 7 plus but same thing -_-
Sidenote:fastboot device from phone drivers kinda works(?) But still im not able to do anything because im stuck on waitig on devices when i want to flash
To manage an Android phone from PC you at least need
1. ADB - provided by Google
2. FastBoot - provided by Google
3. Android-USB-driver provided by OEM/Carrier matching your phone
and nothing else.
Have all of those and im stuck on waiting on devices after i reboot to bootloader. Seriously annoying maybe i will try on other pc and see what happens but its not really a solution
If your phone supports Fastboot - take note that not all phones do - then when Fastboot returns "Waiting for device" it's a driver problem: Install correct driver.
True but as i wrote official drivers don't work it's on the phone after all. Rest doesn't work too then . Heh
