[Q] Please HELP no idea what to do - Sprint LG Optimus G

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.

[Q] Use computer to turn phone on?

So short story, my galaxy nexus's power button doesnt work anymore. It stopped working for no reason yesterday, yet when I plug it into the charger the charging screen comese on. I want to be able to power my phone on so that I can get all the information onto my computer so that I can easily transfer stuff to my new phone (replacement gnex coming tomorrow) Is there a way I can turn on my phone without using the power button? Any help would be much appreciated.
If you've got the SDK or just ADB available, you should be able to use the command of "adb reboot" to get the device to boot up. Could be wrong.
Can someone guide me in the direction I need so I can do this adb reboot?

Download the ADB file (usually bundled with Fastboot) from any one of these guides that requires it. Or just Google for it.
Unzip all of that, use command line to get into it's directory, hook your phone up over USB, and type:
Code:
adb reboot
Again, not sure if this will work when the phone is off. If it will work, I think you had to have USB debugging turned on. Its not working for me currently on OSX. So I don't think it will. Maybe there's a different ADB command that can help you.
Its a long shot. There are probably better options.
I'd agree with adb reboot if your computer will recognize it from this mode...
Use the guide linked in my sig to set up ADB if you need.
I'm a newbie to all this, but I don't think anyone here mentioned the necessary step of downloading and installing your phone's specific ADB drivers to your computer.
So, to recap:
Download your phone's ADB drivers on to your computer and install them.
Plug your phone in.
Go to your command prompt and type 'adb reboot'.
I think. I'm new, as you can see by my post count and thanks meter.
I tried to adb reboot. Unfortunately the galaxy nexus cant be recognized when the phone is off. Disappointing but not the end of the world. Thanks for everyones help.
If adb works in download mode you could make a jig to get you there.

ADB device offline - after upgrading TWRP and 4.2 ?

So I have had my Galaxy Nexus since the day it came out, I rooted it before I even activated it.
Like many, I have used all sorts of different ROMs over the year period.
I have never had any problems with adb or anything. I have pushed and pulled files and all of that numerous times.
Until yesterday, I finally upgraded my recovery from an really old (first touch based recovery) to the newest TWRP. It worked fine. I put my phone into fastboot mode, and was able to flash the new recovery through the command prompt (adb/fastboot) on my PC. Then I switched to a new 4.2 rom (Paranoid android 2.99)
So today, I wanted to try some editing on some system files, so I went to go pull some files off of the phone (using adb of course), but now it just tells me that my device is offline.
I tried
"adb kill-server"
"adb start-server"
"adb devices"
It lists my device number, but just says "offline"
I tried to update everything. (Samsung main Drivers - Google's USB SDK drivers - and the newest version of android-sdk)
Also made sure that my USB-debugging was set on my phone.
Even if I put my phone in fastboot mode, it doesn't recognize it anymore. Which is weird because just last night it worked perfectly fine when I upgraded my recovery. I am frustrated to no end...... Can anyone else tell me what I might be missing here?
Nobody?

only thing i can think of right now, before suggesting omap flash or odin, would be try a different usb port, another computer, another OS!
try installing the latest CWM recovery and see if it helps.

Try going to settings and look for something related to Root Access and it would have three options:
1. Apps only
2. ADB only
3. Apps & ADB
Choose the 3rd.
You might have to hunt the exact location under Settings where this option will be available as I don't remember them exactly.
Hit Thanks, if this helps...
I looked, but I don't see those settings anywhere.
I tried multiple USB port's. Switching from my USB 3.0 ports to my 2.0 ports. nothing. I can still access the phone storage. So I know it is still connecting to the PC. I could try to boot up linux, but I don't have any of the driver's and sdk tools on my linux drive, and from what I heard it was hard to get it all running in linux.
I guess I could try to change recoveries from TWRP to the newest CWMR,
but last time I turned my phone off, put it in fastboot mode, adb didn't recognize it. So im assuming it won't let me flash anything. Unless fastboot sees it but adb doesn't?
I mean my phone is working perfectly fine, running the new recovery and rom. But I have to be able to connect to adb. Not only for modding but in case of an emergency where I would need to flash.

I understand your situation... Since you were not able to locate the option suggested, a little Googling answered it's location, check for same and confirm:
Settings > developer options > root access > apps and adb
This should hopefully help resolve the issue.
Hit Thanks, if it helps.

hi. i try all this ways. i know that my usb debuging have problem, in development option i'll checked this, and it says enable. but infact it's not enable and still i got device offline error.
also i use z4root app and when i touch on root, it says that rooting need usb debuging enable (please enable it)!!
then move me to development setting to enable that, but this was checked and enable.
is any way that we make device online from my phone? for example using terminal emulator to turn on usb debuging or turn it off. this way is only my way! any one know some trying this?
i also use usb debugger app, but it move me in settings too! LOL
i need enable my device to root that.
thanks every one
I know this is an old topic, but if somebody else googles it, I had that offline issue, the solution was to upgrade adb : http://stackoverflow.com/questions/10680417/error-device-offline
You simply need to upgrade to the latest version of adb. Went thru this a few weeks ago.

[Q] Help with unlock/root, ADB driver fail

I'm having issues with unlocking/rooting my nexus 7 2013.
I downloaded and installed the nexus root toolkit at wugfresh.com
I've followed all the instructions precisely. However, I always failt the ADB Driver test.
Here are the things I've found while trying to troubleshoot my problem:
1. When I enable usb debugging mode and plug in the nexus 7, I NEVER received the RSA Fingerprint authorization screen.
2. I've installed all the drivers and when it's plugged into the PC, it is recognized as a "google nexus ADB Interface": i.imgur.WHAT/f5Rk5qg.png
3. Inside of USBDeview it is recognized as mass storage device (color purple instead of green): i.imgur.WHAT/r4SwmVM.png
4. Under My Computer I am unable to reach the harddrive anymore.
I believe this is what is preventing me from moving forward. I know this because I've plugged this into my co-workers PC (he already had NRT installed to root his 2012 Nexus 7 awhile ago) and unlocking it on his PC works fine.
5. After uninstalling the drivers installed with NRT and uninstalling the NRT, I still can't access the drive as I could before.
Any help would be appreciated.
This is my first post so I cannot post links to the image... On #2 and #3 replace the i.imgur.WHAT with i.imgur.com
I had the same issue with Wug's toolkit. I finally went the google route using the SDK and usb drivers and it worked like a charm. I would try that method if you feel comfortable enough. Here's a guide to help with that: http://forum.xda-developers.com/showthread.php?t=2382051

I think my issue isn't with the toolkit but with the drivers on my computer right now. I'm not sure how to fix the driver issue i'm having. The link you provided only links to drivers I've already tried.

This is usually because you are not running the latest adb version 1.0.31, but might be for other reasons like the adb that is running in the background is the older version and you need to adb kill-server then adb devices to restart it
Don't underestimate the power of reboot. Sometimes things get in a weird state and even though you have it set up properly, the changes won't really kick in until a reboot.

I didn't see mass storage device where you highlighted in red.
You shouldn't see USB mass storage device with this device. It doesn't support it. Only MTP mode. If you are seeing mass storage device, then probably some drivers are out of whack and you should use usbdeview to remove them.

There could be many explanations for this. The simplest one is you have USB debugging enabled. Try disabling USB debugging. If that doesn't work, try PTP mode settings->storage->3baroptions If you see PTP mode, but not MTP, then it is a USB ID problem. If you don't see PTP mode either, you probably need to remove some drivers, reboot, and reinstall the drivers.
msellsio completely
Well... my work day ended and I figured I would simply try to do it at home.
I got the drivers to work at home. The nexus was already unlocked so I click on the root button.
After clicking on root, it looks like my tablet got stuck in Bootloader mode, IE in the videos I saw people doing it, it would restart and go into bootload and do something then restart again, mine restarted and just stayed on the bootload screen until I pushed the on/off button (for yes to start).
Now it loads into the tablet and I get about 17 error messages of
"Unfortunately, Google Play Services has stopped" and
"Unfortunately, the process com.google.process.gapps has stopped".
So now I have no idea what to do, I can't even use the damn thing anymore.

Do a factory reset
settings->backup&reset->factory data reset
If you can't get into that, power down
then press Power+VolUp until you see Google, then let go.
You'll see fallen android.
Press and Hold Power, then press/release VolUp, then release Power
Use VolDown to highlight wipe data factory reset, then Power to select.

Thanks for this.
I FINALLY got everything to work.
1. I did a factory reset (the 1 thing i was trying to avoid). This fixed the issues with the error messages.
2. I figured out what went wrong with the root toolkit. I decided to try and do the rooting manually, while trying to flash the recovery file, it was getting an unknown error. So the toolkit was basically getting stuck there. It took me 2 hours to figure out that this was happening simply because I was using my front USB3.0 ports. I switch to the back USB2.0 ports and the flashing worked fine.
3. Since I had already managed to flash teh recovery file, I deleted the universal adb drivers and let windows handle it, it installed the regular drivers and I finally managed to access the drive. I was able to upload the supersu file thus completing the root.
I still don't know why the ADB drivers won't let me access the drive though. Guess this mystery will have to be solved anytime.

If you can access the Nexus 7 over MTP (ie as a drive) while USB debugging is disabled but not when it is enabled, that is a known issue and here is a fix.
http://forum.xda-developers.com/showthread.php?t=2391236
If you can't access MTP at all, I would also look at that link to d/l Nirsoft USBDeview and remove all the drivers for the nexus 7 (sort by date and select all the nexus 7 entries) Let the drivers reinstall from scratch.

Hard Bricked LG E980 USB device not recognised

My LG E980 is bricked. I can access download mode and that is it! I am unable to boot into recovery,
and the hard reset screen simply sits there forever. My computer only recognizes my device as an "unknown usb device."
I'm unsure what can be done about this, but I feel like this is better than the infamous QHSUB icon displayed when the device cannot be recovered.
Does anyone have a remedy for this problem?? I have GOT to fix this phone and can't afford to Jtag the device, but I'm losing hope that this is possible, PLEASE help. :crying:
Have you installed the LG drivers for your pc and tried the unbrick method?
Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660
There is never a time when this device cant be recovered. even the qhusb is a fairly simple fix. ill go ahead and make a sdcard boot image tonight. do you have a 32gb sdcard? (or larger) and an sdcard reader, if you have those two things i can make an unbrick.img that you flash toi the sdcard and put in the non-booting phone and it will get you to download mode/recovery mode. ill have to check out what partitions are where as i dont wish to include my efs along with it all .

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned. I really just want to get back to stock, but I can't manage to get both the windows 8 computers I've tried to detect the phone in download mode. Ever since I switched to the Candykat rom 4.4 the computer wasn't able to recognize the phone, even when the phone was fully functional inside the rom.
I have tried it on my dads windows 7 laptop as well with no dice. Instaled LG drivers, uninstalled LG Drivers, uninstalled device from the Device Manager. I've done everything I could think of. I previously was in a Philz touch recovery, but every rom I tried to flash wouldn't work. I tried to flash another recovery from inside it and then the device bricked like it is now. What a head ache. If you think this method would work, I am more than willing to try it, just unfamiliar with what I need to do on my end.
Okay

I will give your method a shot, but I have done this a lot already. The only thing I can think of is I usually unplug the phone from the computer right after deleting the drivers and uninstalling in device manager. Maybe I should just leave the phone plugged in and see if the computer automatically downloads the drivers, but I don't think it will because I've tried to update the drivers before. It gives me an error code "10" and says the device has malfunction or stopped working This phone has been undetectable via USB since flashing the candykat 4.4 rom. Every computer I've tried (3) and every USB cable (3 again) has displayed it as an "unknown device"

I dont know lg's download mode, kdz, tot etc all that well. im more of a samsung guy. however qualcomm since the s4 chipset has allowed for sdcards that are properly formatted to boot the os instead of the internal emmc. here is a decent guide, just need to make teh image for this device. this will let your device boot no matter how bad it gets you are welcome to try with 16gb, the rule of thumb i know of is as big as teh emmc is use that same size or larger sdcard, however some people have had sucess withs maller, just not many that i know of. http://forum.xda-developers.com/showthread.php?t=2439367
however afaik the only way to reflash teh bootloader partitions is via kdz/download mode so perhaps the sdcard will let you get into that mode and then you can flash, so long as you keep your sdcard like that it will boot fully, but in order ot get your sdcard back you need to repair teh files on your phone .

Wow, that sounds awesome. I followed most of that. I access download mode on the device by pressing vol up and down simultaneously and plugging in the usb cable. I am more willing to try this, and if it works I will pay you from my paypal. I guess all I need now are those files to run to the sd card. I read the tutorial you posted for the samsung and downloaded the windows disk manager. I am eager to try this method, though it is admittedly very new to me.. If you can post those files, I will follow the instructions you give and pay you a little bit of money for your help!
I am a broke college student so it won't be much, but I really appreciate your response and information on this method with the qualcomm s4.
Here is the unbrick image. follow the guide for your platform (gunna guess windows) and write this to your sdcard after backing it up. from there you need to restore your partitions by flashing them .

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.
Just want to say thanks for walking me through it this far, I feel like I'm close hopefully but unsure what to do next.

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.

you wrote the image to the sdcard? i wonder if its because you still have the low level bootloaders that it may not be booting from the sdcard, normally this is done to fix qhusb errored devices. as for restoring the partitions all you would need to do is one its booted up push the unbrick image to the phone and use rooted adb shell to write it back onto your phone.
Possible hope??

I meant I used the windows tool to write the debrick.img to the sd card. But no dice, the device isn't recognised.
However! I installed a driver clean up tool and now if I plug in the device it is recognized as Android Original ADB Interface.
The LG Flashtools even says the port is ready! But I get the error code "10" "device cannot start, A request for the USB device descriptor failed."
So now I am stuck on that instead lol. This just sucks.
that sucks about the sdcard, it must be because you arent "truly" bricked. sorry i thought it would help ya :/.
What is the driver repair tool you used? I know this thread is old but I'm having the same problem. I was trying to root my E980 and now my computer wont recognize my device. The phone works perfect, its just when I plug it in to the computer it isnt recognized. How can I fix this?

Just wondering if anyone's come across a solution to this besides a sledge hammer... been having the same "Code 10: Device failed to start" when in Download Mode, though Windows finds a driver fine when the phone is stuck on the LG screen... doesn't help much, though, 'cause it won't receive adb commands. I manually installed the LG USB Composite Device driver, which added a modem and a COM port, both of which Windows recognized to be active, but the LG FlashTool USB Viewer showed no open pipes. I'm a relative noob, so please feel free to point out the obvious, like an alternative to adb that the phone can always receive or a way to brick it the rest of the way so the MicroSD trick will work.
I came across this problem like the OP and just wanna let everyone know that you have to use computer with USB 2.0 port then the driver issue would be fixed.

Fastboot mode Started - help

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
