[Q] G2 not being seen by PC

Hey guys,
I tried getting some help for this over at the Nook Color threads because it all started *after* i rooted my NC, but no one's been able to explain to me what Ive done wrong or whats happened...
So here's the sitch.
o I have ADB installed, but it only activates in device manager when the nook is plugged in, not the G2
o When the NC get usb'd to the PC, it fully registers and gives me access to the SD card on it
o .... where as the G2 just sits there and says "yay im getting power!"
o ,,,, BUT if i plug it into a HUB rather than directly into a usb port on the mobo or front, the PC (win7 x64 ult) seems to see it but doesnt know how to properly assign a driver to it and gives it UNKNOWN
o also i checked the usb-adb ini file, and it lists all my other devices in the hardware cues BUT the G2, which means it hasnt properly registered since then or never had a proper profile to begin with in the PC. It even has my older mt3G listed which I havent plugged in since all this started.
Ive tried multiple driver types, but literately, NOTHING has worked. Its like the G2 isnt even properly registering in the computer when connected. I tried a factory reset, but still no luck. Is there anything beyond a soft fact reset for an unrooted phone? I mean, i need COLD AS STONE back to day 1 reset.
Please help, I really want to root this :'<
and no, the only way now to access my sd card is to turn the thing off and use a reader. Like i said, it literately is NOT seeing it :<

Wrong section. Ask in the Q&A, not the DEV section.

Try installing HTC Sync, even though it doesnt work with the G2 because its sense based, it will install the proper drivers for you. This worked for me.
Heres the link:

Another method would be install pdanet on you phone fron the Market, then install pdanet for your computer from here and it should install the drivers when you plug your phone in with pdanet app running:
http://www.junefabrics.com/android/

I tried the Sense link, but I couldnt find the download option for it.... anyways, heres a more precise description of the issue
When I go and install PDA Net, it loads up the drivers, but the computer literately is not even registering that a DEVICE has been plugged in via USB. I dont even get the USB connect prompt on the phone!
That's what Im saying, something is up. I need to take the cable with me and try this on another computer now that I think about it to rule out that something isnt damaged on the phone...

What ROM are you using? Gingerbread ROM's act like the (for now), at least from what I understand. I tried CM7 and sure enough - it acted just like what you're describing.

But thats the whole thing, im not using a ROM, its just the stock OS build. if i was using a ROM, id have tried removing it and reloading it, but this is on a phone that isnt even rooted yet... actually... should I try going temp root again and see if that fixes anything?
Whats the best way to do that now since I keep reading Vision got pulled away because it was damaging phones or something?

Okay, so i tried plugging it into a diff computer.... same result... so whatever it is, its the phone.
Any ideas XDA pplz?

Has it seen the g2 before? if so, get usbdeview, find the drivers in there that would be used for the g2, delete those. Snag PDANet and download that, plug the phone back in and see what ya get. You will get the pop ups again about the new software being loaded since it will have to find and reload drivers for the phone and PDANet will have the drivers you need.

Like the guy above me said, DL or re-DL the drivers (though none should be needed if you're using it as a storage drive, the comp sees it as a usb drive). Is it charging your phone when you plug it in? It's rare, but the USB cable may be bad.
The only other thing I can think of is that something went wrong and the phone isn't releasing the mount to the sdcard, in which case you should try rooting and using a different ROM or a stock rom and it should help.

Well thats the whole thing, the computer doesnt even see the USB part of it. Thats been my whole issue. The computer doesnt see the phone or the usb drive part. It straight does not see the phone at *all*! Doesnt even show up in Dev Manager, but yet it gets power. I even went and got a new micro USB cable, fresh, and still nothing.
im getting to 86 the os and reload Win7, im like super uber pissed over all this because i cant figure it out. I dont even know whats wrong >_<!

Just for kicks (because I had this exact thing happen to another phone of mine - the slide) you're rooted, which means you have clockwork right?
Reboot into recovery and go to the 'mounts' part and select 'mount usb'. Do that with it plugged into your computer and let me know if the phone shows up then. That's the only way I could put it in mass storage mode. I flashed something other than cyanogen's rom and BAM, it worked like it was supposed to (Linux did mount cyanogen though - weird).
If you want to go back to 0 day with your G2, search 'PC10img' and download it. DO NOT FLASH IT YET, you could really screw up your phone since you have s-off. Go to the wiki and scroll to the bottom, it tells you how to get s-on. Once you can verify that you have s-on, proceed to flashing the pc10img.
Wiki

Okay, so, Im way better now. Apparently I managed to get s-off and root ability via
http://forum.xda-developers.com/showthread.php?t=837315
when i reloaded and got rooting ability, somehow, I now have a detectable sd card again.
I dont know how, I dont know why, I just know that Im going to throw CM6.1.1 onto this thing and be rocking it hard
Thanks again for all your help guys, it was awesome to know XDA really helps out its followers
EDIT:
Okay... so now Im mixed. I have a rooted phone, with CM6.1.1, but still doesnt properly recognize when plugged into the PC.
oh well, I already called TMobile and their sending me a new phone under warranty. Its gotta just be a busted port in some way for detection. I dunno. >_<
But still, thanks a lot guys. Means a lot

[Q] Please help a Noob

OK. I think I've done my due diligence. I've scrubbed the forums for 2 days, I've googled it and I still can't figure out what I'm doing wrong.
Friend gives me this rooted LG OGP. Awsome! Works great! Then AT&T or LG sends an OTA update that bricks it :crying:. Read Aryan1312's sticky thread in this forum and get all pieces together. By now I have the 3.8.1 drivers AND the newest 3.10.1 drivers, LGFlashTool 1.8.1.1023, along with the newest 10P TOT file. I got the Flashtool to stop asking for PW and I think I'm ready to go.
But then . . . Plug my phone in and Device Management doesn't know what to do with phone. Reinstall drivers pack from LG website. Still no dice. Hmm. Phone is in Team Win Recovery Project v2.6.3.0 recovery screen (I guess that's what it's called) and computer doesn't know what to make of it. Hmm.
Maybe I can put it onto a microSD card and copy stuff over to phone? Maybe flash a different ROM through TWRP? Let's try that. I copy files over to the external SD card, put it into the phone, restart phone, hello TWRP, Advanced-File Manager option, WHY CAN'T YOU SEE THE EXTERNAL SDCARD??? Isn't it supposed to be there under /extSD?? It's time to ask for help.
Question: How do I get my Win7 PC to see the phone as a removable drive/external drive/whatever you call it so that I can get this info over?
I know that I have to change Port #'s after Win7 sees the phone. I just can't get there . . . yet.
- What I've tried:
Reinstalled drivers (both versions) and restarted between trying to plug phone in.
Tried installing phone drivers manually. Still doesn't mount as external HD as far as Win7 is concerned.
Called friend to ask his opinion. He doesn't remember and tries to tell me this is why Apple is "better".
Scoured the web to see what to do. Found articles about this same thing happening and all point to Stickied Post on this XDA forum
I did RTFM and am still lost.
---- Sorry for the long post, I just thought that people who wouldn't mind helping would appreciate the extra info.

1. Is the first pic with the phone connected to the pc?
2. If yes, have you tried to manually update drivers, while in device manager
3. I know that this is going to sound funny but have you tried a different USB port. The reason I ask is I had the same problem LG Optimus M and the phone was down for a couple of days. I tried everything and was about to call it quits but for some reason when I changed USB port the computer saw the phone and I was back in business. I am not saying that will 100% work but it is worth a try.

Yes I have. I think I did figure it out though. I put the device into "download mode" and my computer could see, and communicate, the phone.
To put my phone into "download mode" I did the following:
I connected the phone to the computer physically with USB cable
I turned phone off.
I pressed BOTH volume buttons and held the power button while phone was attached to computer.
With BOTH volume buttons still pressed, I released the power button.
The phone screen was black with a little dialog box in the middle saying "download mode"
I could then use LGFlash Tools to flash Stock AT&T TOT file back into phone. Took 519 seconds to complete the stock flash.
New problem arises, After flash, I do NOT have any 3G/4G signal. I can use the phone to make and receive phone calls and text messages, but I CANNOT use mobile internet unless I have it connected via wifi.
I installed the Debloated ROM and "tried" to flash 980 Baseband.zip but when I tried to install baseband, CWM gave me a permission error and said install failed. I haven't been able to use mobile internet since. Any help???
-- Again, sorry for the lengthy post. I figured that I might not be the only person who has gone through this. I see a lot of viewers to the thread so I think other people might be having same troubles as me.

It sound like you need to manually set the APN. Do a Search for your provider.. ie AT&T T-Mobile the setting is under Network/Tethering & Networks/ Mobile networks/ Access point name/ Hit Menu Button and New APN

You are the MAN / WOMAN!! Thanks for the help. That fixed it.
For posterity and to help another "noob" stuck in my case later (maybe months down the line)
This is what I've done up until now in plain text:
Used LGFlashtool to flash AT&T stock "10k" build
Went into Settings Icon>General>Developer Options>check off "USB Debugging"
Used "E980 Universal Root" from forums to gain Root access (verified with "Root Checker" from Playstore)
Used FreeGee to get TWRP recovery installed (rebooted into recovery with "QuickReboot" from Playstore).
Used TWRP recovery to install "E980 Baseband.zip" from forums
Factory Reset
Setup new phone and input APN settings (located in Settings Icon>Networks>Tethering & Networks>Mobile networks>Access point names>Menu button "New APN"/input carrier values/Menu button "Save")
Now that I know how to get back here, I'm going to scrap the stock ROM and try to do this whole process with a custom ROM. . . and another flash-a-holic is born. The learning journey continues.

Welcome:beer:
*KCCO*2SHAYNEZ*E980*

That is what this forum is for.
I have been helped out a lot from the group and I just thought it was time to pay it back. It is good to hear that you got it up and running. But one last word of advise BACK UP, BACK UP, BACK UP, and when that is done, back up the back up to the computer.

Putting a 100$ bounty for someone to fix my phone (SGH-i317M)

I am at my wits end to try to repair my phone. It is softbricked and responds to download mode only.
I've had chat with xda members and read threads on it:
http://forum.xda-developers.com/chef-central/android/nand-write-start-fail-odin-soluction-t2851096
http://forum.xda-developers.com/galaxy-note-10-1/help/help-help-unbricking-galaxy-note-10-1-t2872125
and many others. in the end, my phone is still stuck with the NAND Write Start error with odin.
I know it happened after i tried creating a backup of my phone in recovery mode (phone was rooted with cf auto root and had a version of CWM on it). CWM gave me a warning about possibly bricking the phone, i agreed to the warning beacuse it always worked in the past, but when i rebooted, it was bricked this time.
this phone is not dead but samsung won't fix it beacuse it is rooted. I refuse to throw it away. I have read many people have it this error since kitkat 4.4 so surely there is a fix somewhere. I am hoping somebody will be more resourceful/experienced than i am.
I have tried changing to several different USB ports, without a hub, using original cables (bunch of different ones too) in many many different order and fashion. I tried enough variation to be convinced it is statistically impossible that all my hardware that was previously working for flashing has stopped working all at once. aka - it is not a usb port or data cable problem
may be related to data charging port on the phone though I highly suspect it given how it started.
I tried different roms, different versions of odin, i tried depackaging and repackaging roms, i simply do not know what to do anymore.
i tried reflashing with kies but kies just dies on me.
i tried flashing it with adb but adb won't even connect. when i plug the phone windows recognizes it and usb driver seems to work ok (not getting an error)
I have uninstalled and reinstalled drivers several times, rebooting in between installs. no difference.
i tried flashing different bootloaders as well as entire roms, no difference
I tried changing the pit file but that failed as well (odin couldn't even write the pit so my phone is not dead even if i failed pitting it)
i have access to both windows and ubuntu linux if it makes a difference.
Here are the terms of the bounty:
Price : 100$ (payable by paypal from eniac0 @ "some google mail domain starting with gm"
goal : find a fix that works on the latest firmware for SGH-i317M (Rogers, Canada)
how : i don't know but i need to be able to reproduce it. I am not new to flashing but anything advanced will need to be explained clearly.
I don't really know how this sorts of request usually turns out but i am serious. you even got my google mail address to bill me up if i fail to pay.

have you given a look at this thread? http://forum.xda-developers.com/showthread.php?t=2711825 it might give you some ideas to help you out. also did you try flashing a new recovery to see if you could at least get it to boot to that?
dont care about the bounty just trying to toss something out there that may help you

Did you ever try flashing the stock recovery - JUST the stock recovery - through Odin?
If not, grab the recovery.img and make your own tarball for Odin in Linux.
Hopefully that will flash and get you closer.

Since you mentioned Ubuntu, you can also try using heimdall instead of odin... http://glassechidna.com.au/heimdall/ . Unfortunately, I think it may be a hardware problem?
Since you are willing to pay to have it fixed, if all else fails, you can always send it off to http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-note-jtag-brick-repair/. It will actually be cheaper than what you are offering to pay ~$40 + shipping
good luck

Thanks all for your help, I've messed around and gotten no closer. I'm beginning to lean on a hardware failure, perhaps from the usb data port either that or the way bootloaders are packaged in kitkat 4.4 is different. which is why initially this thread gave me hope: http://forum.xda-developers.com/chef-central/android/nand-write-start-fail-odin-soluction-t2851096 but i tried far too many times now to believe I'm going to succeed. In fact, I've gotten confused as to what i tried, in which order, with which rom. I'm basically trying anything and that's a recipe for bricking the phone for good. so i've stopped.
I'll also thank kozmo21 for the link to the repair shop. i was unaware this existed, as a last resort I'll be sending them my phone. If it turns out they are able to repair it, I'll honor my word and give you something for having been part of the solution.

Have you tried going to sammobile and download the newest firmware and only flashing that in odin?

Use CF auto root. Put the phone in download mode and flash it in Odin. I soft bricked my phone and it fixed it.
Also this guy had great walk through videos on how to do everything you need.

If it works to fix your phone. Keep your money. I'll take the karma points for putting you on the correct path.

More than likely its a bootloader issue my phone did that and all i did was flash the bootloader then it worked again but hes done so much idk what he needs now that's y i said to try a firmware to see if that helps

Download toolkit and select option to push file into phone.
Download a ROM of your choosing, push it into your phone, restart in recovery mode and select file.

Update?
Did you get it fixed? Just my two cents, in case you didnt, I had a similar problem and alll I did to fix it was flash the JediMasterX2 ROM with CWM and everything worked out.

[Q] [x-post from LG G3] D851 unroot / restore to stock

I recently picked up a D851 (TMobile). I rooted it, but did not replace the ROM or install a custom bootloader.
Last weekend, the phone started randomly rebooting. Watching logcat via adb showed me several random apps throwing sig11s, after which the phone would give up and reboot. Cycle repeats.
This looks like a hardware issue, as the apps that crash change on each boot cycle.
I arranged with TMobile to swap the device, but they cautioned me that the phone must be returned to an unrooted state.
I've had a hell of a time with it from here. My first try was to install the LG drivers and the PC Suite under a Windows VM, as I do not run Windows at home. Enabling USB passthrough for the phone to the VM let Windows see the phone, but the LG drivers would invariably fail with 'Device cannot start. Code 10.'. Likewise, the PC Suite couldn't find the phone.
Next step was to throw together some spare hw and install Windows 7 on that (a desparate move, to be certain. ). The LG drivers can now recognize the phone, so that's a definite plus. The LG PC Suite, though, claimed that my phone could not be upgraded. Wonderful.
Next step was to try this tutorial: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html . I was able to get further with this method, but as it begins to flash SYSTEM, it pauses, and then dies with 'We can't communicate with Phone'. End result - I now have a soft bricked phone. On the phone, I see the port - COM41 - appear, and the usb animation starts to spin ... and after a few seconds, stops. It's at this point that Flashtool throws the Can't Connect error.
I next tried following this tutorial: http://forum.xda-developers.com/showthread.php?t=2785089 to flash a KDZ. The newer LG Flash tool used here can't create a connection to my phone for flashing.
I've run into a wall here. Any ideas on where to go next? I need to reset this phone back to a working stock state so that I can send it back.

Also - as silly as it sounds, make certain you're using the USB cable that came with the phone. This has solved problems for a lot of people when trying to revert to stock.

I wasn't initially, but I did switch to it last night. Still no go.
I suspect it's either the phone itself (see above: re suspected hw failure), or the PC in question (nVidia chipset on this old motherboard, and I've had more than a few problems with adb talking to phones on nVidia motherboards). I'm going to try Bacardilimon's suggestion tonight, on a PC that has *nothing* nVidia-related in it, before I throw in the towel. As it is, the failing phone needs to be back to TMO by the middle of next week, so I'm all but out of time to resolve this.

There is a link in the general thread on how to return to stock including a method using twrp. It's a sticky thread at the top I've never done the twrp method myself but it can more than likely be done without a computer. Twrp can be installed via Playstore if you don't already have it

Anyone who puts each and every download link for software referenced by a howto behind separate timed appearance links that you have to ALSO enter an annoying captcha to enable should be shot out of a cannon - or, at the very least, have their howto ignored by the rest of the world.
Suffice it to say, the quality of that page doesn't give me much confidence that this will work any better than what I've tried already. Since I've already wasted a crapload of time on this project, and more on following those damned links, I'll give it a try tonight, but I'm not going to hold my breath.
Is the author of that page an XDA member? If so, please let me know who he is, so I can berate him personally. Thanks.

There is a link in the general thread on how to return to stock including a method using twrp. It's a sticky thread at the top I've never done the twrp method myself but it can more than likely be done without a computer. Twrp can be installed via Playstore if you don't already have it

I'd consider doing that, except as I mentioned, the G3 in question disconnected during a run of Flashtool, rendering it without a working OS to boot to. The phone now boots straight to download mode. The good news is, it's now officially unrooted. The bad news is, it's also officially bricked until I can get an OS flash to work.

OK I gonna keep it real with you. You can either enter the captcha and fix the issue or throw the phone away. Yes he is a member and for every phone that is out their he has its own page doing this for us. If you can't fix your phone with his method then it not the method but you. I have used this for many bricks. It works and it works great. Sorry if he making you do a little typing but like I said u can use his method or keep trying the other methods. Good luck

After going through the painful process of clicking his links, I found that everything I downloaded is the same thing I already had, except for Flashtool - lgg3root's is actually older. Even the TMO firmware for my phone and the dll are both exactly the same, and I checked by running md5sum on them.
But hey, it must be me. There's clearly no other technology-related cause for this issue. I obviously don't know how to follow a howto, right?
Thanks for 'keeping it real'.

Not likely.
In any case, it failed again. The video he did gave me the exact same steps I followed elsewhere, and unsurprisingly, it failed with 'We can't communicate with Phone', after beginning the flash process. There is something else wrong here, though I'm not certain if the failing phone is at fault or the PC in question is causing the issue. To be crystal clear, the flash process starts, and then, at a random point during the flash, it completely stops, and Flashtool eventually gives up and throws the aforementioned error.
Any other ideas? If not, I'm going to have to try another PC to rule that out as the culprit. Sigh.

Mine gave the same error as well as couldn't communicate with server but the flash process continued running and the phone rebooted took about 3 minutes u learned not to touch any of the popups on the screen during flash and sorry I missed the part about no OS I thought you were booting to recovery... Driving while reading not the best idea

Nope, the phone is definitely not doing anything - the usb animation on the G3 completely stops before Flashtool throws the error.
And damnit, quit reading while driving. You can do that later.

Moved the hdd Windows is installed on to another PC with a different chipset. After it updated drivers, I tried again. Flash proceeded partway, then died. Reset phone, Flashtool reststarted flash from scratch, flash died at 15%.
15% is interesting. While I've seen the flash die at various points, 15% is the one that was most often repeated. This tells me the failure follows the phone, not the PC - which makes sense, as the phone has a suspected RAM failure.
At this point, it appears that flashing this phone is impossible due to faulty hw. Hopefully TMO (and eventually, LG) will accept the faulty phone back with no OS, because there's no way an OS is being written to this device ever again.

Thank you for answering

No problem. There's nothing I hate more than stumbling across a thread where the OP has the same problem I have, only to find it was never updated with the solution.

Good luck man let us know what tmobile says

No USB connectivity at ALL

So I bought a refurb Tmobile S4 from Ting. From day one, when you try to connect to a PC via USB, the computer does not even recognize the phone is plugged in. I have tried 5 different cords on every USB port of 4 different computers on Winblows 7, 8.1 & 10. Thats all 5 cords on all the ports of ALL the computers. I have tried with and without USB drivers, KIES is no go. So brilliant me thinks, "Hey, maybe update the OS". Noooooooooo, says I have an unauthorized modification. So I tried a hard restore.... same thing. I can't root the phone with the MULTIPLE apps, and without USB...
Its a decent phone, I bought a bloody Otter Box for it, I really don't want to get rid of it. Help??
Oh and I'm a noob, techie but I'm more of a PC guy than a phone guy. I'm not just off the turnip truck noob, but don't ask me to make a souffle with the turnips, get what I mean??

You probably already thought of this, but did you try towelroot? It's free, and really worth a try!

Bad USB port on the phone is a bummer! Another thought, have you tried cleaning the USB port with some isopropyl alcohol? Some swabs (don't dunk it, just dab/rub it) might help too.

Actually I hadn't tried. Just installed it. Says my device is not supported. *sigh* I've read something about unlocking the bootstrapper (izzat right? ) but it didn't go into explination as it is a part of rooting so why do that manually. There is just info overload and in having trouble picking it the bits I need. Thx tho Akaska

So I got it rooted!! iRoot had an update earlier and it just worked! Now I just gotta learn how to force the stock OS back in! Yeaaa!

Great! I am glad you were able to get it rooted! There is a TWRP installer app in the play store that will require root and flash TWRP to your phone. Once you do that, you can download ROMs and flash them in recovery mode.

I was wondering if they tried to dial *#0808#, and make sure USB is on AP, and settings is MTP+ADB

What is the model number in download mode?
