My phone is caught in bootloop. TWRP says no os installed.
Plug into computer and device not recognized even after hours of installing/reinstalling/uninstalling drivers/programs and reseting PC.
Cant ADB push rom over to device because neither my desktop, or any of the 3 other laptops in my house will recognize it.
Cant get into download mode to LGNPST because my volume down wont work...
what are my options? I sat in irc for over 4 hours and got 1 response from a guy to ADB push and it was no help cause apperently i am too stupid to install the correct ADB drivers or something, always says is not a correct internal or external command.

This happened to me a few days ago as well I know how you feel... You can try taking apart your Optimus following a tutorial on YouTube and pressing volume down to download mode on the actual contact rather than the button if the contact still works.
I believe LGNPST is your only option at this point, as ADB sideload in TWRP needs a Jellybean rom installed.
sounds like you need some lgnpst in your life
Use the LGNPST auto installer, it'll get the right usb drivers installed. You can then usb adb in recovery. Another option is to use QPST to have it reboot your phone into download mode, after you get lgnpst up and running.
So this morning i thought it would be a great idea to revert back to stock.
i was following the KDZ lg flash tool however while it was flashing (got to about 2%) i stupidly knocked the phone and the usb cable came out....
so now when i turn my phone on it goes to a black screen with
Fastboot mode started
---reset---
---port charge--
i have tried going into download mode again but it still goes into this fastboot mode.
i found a lot of threads on this such as
http://forum.xda-developers.com/lg-g3/help/tutorial-fixing-fastboot-mode-started-t2995854
this got me to install adb/fastboot which i did via
http://forum.xda-developers.com/showthread.php?t=2588979
however when i try and run through fastboot it just comes up as waiting for device
i have attempted to install lg drivers for this but still nothing.
inside device manager it comes up as
other devices - android?
so clearly the computer is recongnising it, i just need a better driver.
I have the ldf ready to go, if only i could get it to recognise the fastboot command...
anyone able to help, i realise there is a lot of information on the web for this, after extensive research everyone seems to suddenly get into download mode each time. which is something i cannot go. and no recovery doesnt work either.
other things to note, just to save questions..
i am running LG D855 16gb.
when i attempt to go into recovery it comes up with the option to wipe device, but when i follow through menu comes back to fastboot mode started.
i attempted to install lg pc suite in hope that it would suddenly pick up the device and go through the fix upgrade errors (to no luck)
so to clarify, i cannot get into recovery, or download mode. my screen is sat on fastboot mode started.
i am running windows 8.1 although i have attempted to plug into a laptop with ubuntu but same story.
any suggestions? i have also seen a through about jtag...but i dont have any screwdrivers at this point so trying to avoid that.
thank you for reading, kind regards
Anyone out there that has any idea on how to fix?
im convinced i just need to turn the "other device - android" into something that can be recognised by adb, but other then the stock lg drivers i dont have anything else.
help?
FIXED - figured it out, i plugged it into ubuntu again and noticed that when it was connected it came up under fastboot with "accepting commands"
i then put my laf.img file into my home folder and
opened terminal
sudo su <enter>
fastboot boot laf.img
phone then went into download mode
as i didnt have any tools installed on ubuntu i then unplugged and plugged into my windows laptop and ran LG Flash tool 2014 and flashed my kdz.
hope this helps anyone who has the problem in future
Hi all, so this is my first post and a last resort attempt at recovering my phone, after hours of googling and downloading everything suggested by various forums, and still being stuck... Sorry for the long post, just trying to list all my attempts to fix it.
So, I've been on stock 5.0 Lollipop (v20n) for a long time, with the only issue being that android OS suddenly will decide for no good reason to make my phone super hot and drain my whole battery in 2 hours flat... Nothing that worked for other people worked for me, so yesterday I decided f*ck it, i'm gonna root and flash Fulmics 5.0, using this: http://forum.xda-developers.com/lg-g3/general/guide-root-method-lg-devices-t3129197 (tried the classic method).
Everything went as per instructions, until I went "Send_Command.exe \\.\COM12 < reboot" and the phone got stuck in a bootloop...
So in other words, my phone is not rooted yet (thus nandroid/titanium backup was not made), TWRP was not installed (so i cant reflash stock kitkat). Latest LG drivers are installed (v4.1.1.0 from http://lgusbdriver.com/windows/lg-usb-driver-v4-1-1-0). Adb and fastboot are installed (http://forum.xda-developers.com/showthread.php?p=48915118#post48915118).
I can boot into download mode (Volume up + plugging in my usb cable), but i cant get adb or fastboot to see my device, when i try to flash twrp.img though command prompt! Downloaded the LG Flash tool 2014 to try and reflash stock kitkat 4.4.2 v10E, but it also can't see my device!! LG PC Suite can't see my phone when trying to connect...
I have removed the LG drivers from device manager and reinstalled the 4.1.1.0 drivers several times, but everytime i plug in my cable Windows (7 ultimate) tries (and fails) to install some drivers for it, even though i installed them already.
I tried to do a factory reset (holding volume - and power button, releasing and pressing them again when i see the LG logo), it gives me the option of doing a reset, but it goes back to the bootloop.
I have installed the Android SDK files (https://developer.android.com/studio/index.html), not the whole 1187mb SDK bundle, just the 144mb installer_r24.4.1-windows.exe. But i cant get my pc to see my device!
Went to a friends house and installed the LG drivers on his pc, installed adb and fastboot (as above), opened a command prompt in the folder where the adb and fastboot dll's are, and neither "adb devices" nor "fastboot devices" lists my phone.
What am i doing wrong???
TL;DR LG G3 d855 stuck in bootloop, but can boot into download mode, no root, twrp recovery not installed, LG drivers and adb fastboot installed on pc, adb refuses to see my device but windows tries (and fails) to install some drivers when i plug the cable in. Factory reset didn't work. Need help please!
Greetings every one ..
I have a half dead Oneplus 3 Unlocked + Rooted
here is my problem
there is no OS in it and i flash TWRP many times via ADB and wont boot to it
and i tried to flash the stock recovery V2.0 and done successfully
the sideload mode Recognize my OP3 but when i try to flash the Oxygen Rom it Gives me cannot read
also i tried the Unbrick Tool when the device is connect it showing me Qualcomm hs-usb qdloader 9008
but when i power up the tool as administrator it showing me (no device)
see here : https://www.youtube.com/watch?v=BIbagVAXJJk
Thanks .
on the unbrick guide try method 2 but completley power off the device and count to 10 when holding the vol up button THEN plug the device in. i had that issue also. if you get errors or for some reason it dosnt show up again try on a diffrent pc it will work
Try method 2. BTW "cannot read" error has to do with faulty ADB drivers, get the platform ones
I did instal the right ADB drivers in fact
still no luck
The ones from platform tools? Since that "cannot read" error has nothing to do with your device. Have you tried renaming it? Rebooting your PC? Last one did wonders for me for some stupid reason.
Hi,
I also had this message of "can not read" in sideload mode, this problem often happens with Windows 10, so I used Windows 7 on another pc and it was OK.
I tried Windows 10 & 8.1 & 7 & XP
still The same problem
What if you flash Twrp and boot into it? Then u can adb push the filemm
I tried via fastboot and its done right
but when i reboot into the new TWRP recovery its stuck in the boot oneplus as same like the Video shown up
book an appointment with oneplus live chat so a service tec can fix it and if they ask if it was rooted say no
Hi,
If you access TWRP, install the Official Oneplus Recovery 4.0.2
In TWRP click "intaller" then choose "install image" and select the file you will have to copy to the phone in recovery mode.
Then restart in recovery mode, choose english, then "adb sideload mode"
From there you should be able to flash your phone with an official Nougat zip.
Do the under windows 7.
It is necessary to install the Oneplus USB drivers and ADB tool on your PC before any manipulation.
Finally I solved the problem
like i said B4 my phone wont boot into TWRP by any chance
i traid all the Officials TWRP one and they stuck on the boot image or power the phone off
i flashed a modified twrp (blu_spark 3.0.3-x) thanks for this beautiful smart man eng.stk if im not wrong
and thank you all for the help
i had similar issue...with several phones.. download Malwarebytes trial version and run it...i had a few stealth root tool kit viruses.causing my system to have a hiccup....
Hello,
today I have a problem with my g4. When I first got this phone 2 years ago I instantly unlocked bootloader, installed supersu, xposed etc and I had no problems at all with this.
But couple weeks ago somethings happened to my snapchat so today I tried to unroot to login to my account on sc. Then i checked that I have to uninstall xposed framework too, but to do this from xposed installer app, root is needed. I thought "no problem, I will install root briefly, uninstall xposed, unroot and login to snapchat". Then I met first obstacle. I don't have recovery mode in phone. when I connect g4 by usb to pc and use adb (by typing adb reboot recovery) my phone reboots and shows green dead android with red triangle. I have to remove the battery to get phone back to life. I remembered that i always used fastboot commands to boot into custom recovery instead of installing TWRP, because flashing it never worked. But now when I try to execute any fastboot command, it only shows me "waiting for any device" in cmd. what do I have to do now? all essential drivers are installed on my pc. phone is showed as "LGE Mobile adb interface" in device manager. when I enter "adb reboot fastboot" it only reboots my phone and nothing else. Does anybody know a solution? I wouldn't like to wipe my g4 from all data. I have read many pages on google and nothing helps. I've tried fastboot on 2 different computers, one with usb 3.0 and one with 2.0 and results are the same. If someone could help me, thanks in advance.

Try another Cable. Even my original LG cable isnt working with fastboot/adb.
have you tried: https://forum.xda-developers.com/g4/general/guide-how-to-enter-fastboot-mode-t3239537
some more Information about Your Phone. usu´d or nornmally unlooked. Stock rom?

Tried with another cable and nothing changes.
I tried to do this method you sent. So when I enter download mode it goes into "firmware update" after couple of seconds, my phone isn't detected on pc and the first command in console "Send_Command.exe \\.\COMx" returns "FAIL".
My G4 (H815) is stock rom, bootloader unlocked normally, didn't do any usu or anything like this. I have only rooted it with supersu 2 times (one time maybe a 1,5year ago i log out from snapchat and had to unroot and root again), installed xposed framework and did nothing else. I don't know how is it possible that I used fastboot on this phone then and now I can't do it. Half a year ago I've installed custom rom on friend's G2 and installed some programs etc. on my pc (because installing this rom didn't went that well and I had to flash stock .kdz or something like that through LGUP/LG bridge/lg flash tool, I don't remember) and I thought that it did some mess but when I tried to use fastboot on another PC, where I've installed drivers freshly, the result was the same.
So what is about "firmware update"? It is obviously stuck on 0% and I have to remove the battery to leave this mode.

Try installing "adb universal drivers".
Also in your computer device manager, with the phone connected, uninstall the device, adb device, modem everything related with the phone. Reinstall and try it after install the universal drivers.
Hope it works, good luck!

Uninstalled everything lg-related from device manager, uninstalled everything lg/android-related through revo uninstaller, installed adb universal drivers, lg usb drivers, everything seems fine, when I type "adb devices" in cmd it shows my phone but, again, when I enter something related to fastboot, it only shows <waiting for any device>.
Is it even possible?? I have not seen any cases like mine in internet - somebody's phone every time was else bricked or somebody would try to flash something and errors like that happened, but I have used fastboot many times on G4 and G2, didn't reinstall windows and everything worked! Why I can't access recovery mode (dead android with red triangle) or enter fastboot or do something in download mode? What could happened?! Is it possible to fix this without wiping data from my G4? I haven't done factory reset for very long time and copying tens of thousands of photos and videos, quickmemo notes, music, voice recordings, chrome bookmarks and everything else to my PC would be a big pain for me.
After all, thanks for replies, and I hope that we will find solution for this.

<waiting for any device> because if windows don't recognizes the device as it should adb will never "see" it.
While on the process, pay attention to the device manager. When you get the message in cmd of <waiting for any device>, uninstall your device and make device manager search for devices.
If still shows you as the same device and adb still waiting, you might have to uninstall the device and install it manually choosing from a list. Now I don't remember how it is suppose to be detected...
During install and uninstall don't disconnect the device from the computer, and remember, use a USB2 port.
I already got that several time. Took me time but that's how I managed to fix it.
okay, guys, it is a shame for me... but I worked out what is wrong with my phone.. maybe not with my phone, but what is wrong with me.
all I needed to do to launch a fastboot was type "adb reboot bootloader" and everything is fine now.
Sorry that you had to give me so much tips and this problem turned to be my stupid mistake, but I'm glad that i won't have to install linux and play with virtual machines to repair my phone
Anyway, thanks for your kindness and will to help, greetings for everyone!
@edit: Turns out that i have one more question. I want to uninstall xposed framework. But there are many versions of uninstaller on their site. Is there any risk that i will "break" my G4 if I use the newest one? I have xposed version 87 and I don't want to do something stupid. thanks in advance.
somebody knows? if I can use the newest version of uninstaller no matter which version of xposed framework im using?
