[Q] recovery install problems lg g2 - G2 Q&A, Help & Troubleshooting

First time posting,
I must preface this by stating I have spent several hours reading xda forums and other online forums for help. I haven't seen this exact scenario mentioned so here goes...
I had lots of problems trying to root my phone. (lg g2 verizon 12b). I followed all instructions as best I could. Problem is in terminal. Running Terminal shows my phone connected but also emulator 5554. I think this is what is causing my terminal to close. Finally after several hours on my pc, I decided to try on my friends Mac. This was "tricky" (I am no mac expert) but I was able to achieve root! YAY!
Now problem is this: I am trying to install recovery so I can a rom installed. (tried on Mac but cannot figure it out) So here I am again attempting on pc, but still I have problem with "2 devices connected" (phone and emulator).
What can you guys suggest so I can "disable" emulator, fyi the emulator loads automatically.
I am using the original usb cable, I have windows 7.
I hope I have explained myself well. And I hope you can help.

Root intercept on froyo????

My friend has the samsung intercept and I was going to help him root it. I have tried Z4root and gingerbreak but they didn't work.
Does anyone have a site on how to root? Or instructions?
I am a very experienced android user and I am very comfortable with ADB if it is needed.
Anybody know?
Let's try again. Does anyone here know?
S.D.X. Everything you need to know for the intercept
Yes I found that method as well. We tried that about twenty times along with another 1 click at xda, z4, and gingerbreak. Is there an Adb method? Also, would rageagainstthecage work?

S.D.X. is a website S.D.X. developers They have several guides to rooting.I rooted mine with a programed called sw updater with my pc but now ther are easier ways.
Ok thank you I will check it out
You're going to need to run one (or several) of the root exploits (until they 'take') and then edit some files manually via adb to make it permanent. See the SDX Developers website as previously noted.
It won't let me post a link but Google this...
how-to-install-custom-kernelrom-on-your-intercept-using-cm01-recovery
I did it with SWUpgrade Tool, but...
1) Even though I could connect and swap files between my phone and my computer over USB, SWUpgrade for some reason would not recognize my USB connection on Windows XP SP 3. This page along with the Samsung driver link on the same page saved my ass...
Google this - Troubleshoot driver error June Fabrics android
2) With the SWUpgrade you have to be really quick and unplug the USB and take out the battery when he says to, or you will not get the custom recovery installed. It took me about 4 tries before I was able to get the custom recovery in my phone.
I previously did the rageagainstthecage method, and while it worked, at one point I stupidly took out the battery when it froze before I had put in a custom recovery and done a backup and I very nearly bricked my phone. It would not bootup after that no matter what. Fortunately I was able to boot into the Virgin Mobile recovery and start from scratch wiping and resetting my phone, but I had to re-download all my apps from the Market all over again which fortunately the Market kept a record of.
I used the first link for the kernel and I am very happy. Just take it slow, be careful, and follow the instructions exactly.

Ok guys thanks for the advice however I have been having one problem:
I cannot seem to get the drivers installed successfully on my computer. It is windows vista x86. I have tried the easytether drivers and the samsung drivers but for some reason they don't work. Any ideas?

[Q] TMOB Brick after CM10.2 flash

After 4 hours of searching for solutions on my own, I am hoping someone might have a solution.
Rooted and installed latest TWRP no problem.
Flashed the CM 10.2 (official release), and phone rebooted and hung on a fastboot screen (last line [1170] fastboot: processing commands)
I've come to find out that I flashed the 802 version of CM 10.2 and not the 801.
Now, no drivers allow my phone to be seen by adb, nor my pc. I've tried many (800, 801, etc.) , including the LG firmware update tool mechanism for the same.
Nothing.
I can boot into TWRP, but have no backup file on my sd to flash back to normal.
I can boot into download mode, but the phone still will not be recognized.
No I am trying the R&D test tool method, but I have a feeling that this won't work either.
Any words of wisdom, other than I'm an idiot for flashing the wrong rom?
Do you have a microusb drive? Or a USB otg cable? Load a proper ROM and see if it helps

Just made an account so I could reply that I am having exactly the same issue and cannot figure out what to do. I've tried every different guide I could get my hands on and none of them seem to work.
Had same issue, i used R&D method and, it worked.
Guys, thanks for replying. I've tried the R&D method, but it sticks at 49%. Have not tried a pc with XP yet. I'm pretty sure there is a solution, but you have to wade through all the posts and decipher best you can. I can't say enough how important it is to read the entire thread before doing anything. Anyway, I'm still working on it. In the meantime I bought another G2. :

[Q] Trouble Installing Drivers

Anyone out there able to help me out? Having the worst time trying to install the drivers for the G2. I had accidentally accepted an update from Verizon, and now I am stuck in a recovery loop. No matter what I try to do, I cant get my Windows 7 machine to install the driver for it.
I am trying to follow this post (http://forum.xda-developers.com/showthread.php?t=2432476) in order to restore my phone to stock, but I cant get any where without the driver installed. I have downloaded the one from the post, the one directly off of the LG site, as well as a few others I have found around the net. My computer at first thought it was a galaxy nexus lol.
Any help is really appreciated.
Used terminal in TWRP to get the system back, but I will want to return to stock.

[Q] Tmobile D801 will not boot FIXED

Just switched over to Tmobile from Sprint and before even signing into google i went ahead and tried to root my phone. Rooting was a success. Used Flashify to flash twrp recovery. Downloaded rooted stock D80110G rom and began debloating it (like I did with the Sprint version) and then booted to recovery, wiped twice, flashed and reboot. Well, now it will just keep rebooting back to recovery and thats it!
I still have access to download mode
still have access to custom recovery
Did not do a nand backup unfortunately
cant mount in twrp because computer no longer recognizes phone!
shows up under unknown devices as LG D801
Tried the stock recovery using LG Flash tool posted in generals but ran into the "can not update because of your device policy" or something like that. Reinstalled and tried it again many times, even switching languages and countries (the last step)
Tried using the ubuntu method posted by partager.info but even ubuntu does not recognize the device. Matter of fact nothing even happens when i plug the phone in.
Tried reinstalling drivers, tried on 2 different laptops (one windows 8.1, one windows 7, and an ubuntu usb boot) and my desktop computer (windows 8.1) and am just unable to mount using twrp because none of them recognizes it!
tried using the adb sideload but twrp just stays trying to load adb sideload forever and adb terminal cant even find the connected usb device.
Tried factory reset but that just takes me to twrp.
I've redownloaded the rooted stock rom and left everything as is. I'm assuming I just need to get it onto the phone somehow so I can flash it.
I have an otg cable but not quite sure how to work it wit twrp or if that's even an option; I've just purchased it.
I feel like I've exhausted my options. Anything else I can try?
Thanks in advance.
EDIT: Should've just used Titanium to debloat instead of trying to do a fresh install! I know I know
Figured it out! not sure how to delete this thread now

Hey sorry, I haven't been on the site for a couple days.
I used the flashtool to go back to stock. Had to enter download mode and work from there. The big issue I was having was a driver issue. Uninstalled every driver related to android and then reinstalled after a restart and that did the trick. For some reason android phones are giving me a lot of driver issues on windows 8.1
follow these steps here but make sure you read a chunk of the thread as the steps in the main post are not complete

friend accepted sprints new OTA. Phone wont boot past TWRP

So, I rooted my coworkers Sprint G2 or LG LS980 using IoRoot a month ago and had TWRP installed on it. prior to doing this I had looked into what it would take to revert it to factory unrooted unmolested state. didnt seem to hard with the lgFlash tool and what not....
Well two days ago he accepted and tried to install the new OTA. he was on ZVA firmware, and I believe the new OTA was for 4.4... well the install of the OTA failed im pretty sure do to TWRP being installed instead of stock recovery. instead of stopping there and calling me he tried to fix it himself... I believe one of the things he did was to wipe the device. as in advanced wipe, select EVERYTING including system....
He gave it to me today rather pissed and asked me to fix it.
Ok, I have bee through MANY threads about reverting back to stock, and it seems I am having a serious driver issue... In my laptops device manager I can see the LS980, but it has no driver installed. I have downloaded many different versions of the LG drivers from various tutorials here and on other websites. I even tried to find them on LG.com, but no luck there.
I can get it into download mode, holding vol+ and plug in USB, but once I try to connect to it via LGMobile Support tool or LGFlash tool, they do not detect it. it tries to load three different modems, and the center one always fails. is there anyplace I can get JUST the driver, not the entire self extracting EXE files?
I was just going to copy a ROM onto the internal storage, but even using the mount tab in TWRP it will not connect to my computer.
PLease for the love of all that is sacred to XDA help me!!! I sadly do not know much about ADB... I have never really used it. at this time it is not installed and I wouldnt know what to install and how to ADB Push a rom onto the phone...
Edit, here is ONE of the tutorials I tried, but since I cannot get the proper drivers installed this hangs when I click the yellow arrow to start it....

okay so have you tried the following from this thread-
If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.

Yea, I have been trying that method... my issue now seems to be that one of the drivers is not installing correctly. So I cannot change the device to port 41. And the app will not see my phone. When I get off work tonight and can use my laptop again I will try downloading advanced and setting that up and see if I can make it work that way. I also read the other thread that was linked last night looking for the two terminal commands to try, both the fota, and the miscellaneous command... found the commands, typed them in, and now my phone boots to the LG logo and my notification light starts scrolling through different colors. I can still get to both recovery and download mode though, so I am not giving up.
Also in that thread someone mentioned koush's generic adb drivers... I downloaded those and will try that as well.
Basically if I can just get my darn laptop to connect to this phone I think I might still have a shot at reviving it.
Multi color led makes me think, wing kernel. Like installing zvc kernel over zva system modem.
You may have to uninstall all lg drivers, and reinstall
Sent from my Nexus 7 using Tapatalk
Well it was running fine until he tapped accept on the ota so I dont know how he would have gotten the wrong kernel.... I have uninstalled the drivers a few times and reinstalled different versions. There is always one that fails when I plug in the phone. Plus I get a message on the device about mediadata unknown, or not found.... something like that. I know before he called me he tried the wipe option in twrp. I know on my galaxy s4 we were not to use the wipe data command in there, I'm thinking he did...
But I can still get to download mode so if I can get my laptop to recognise it I have faith I can lgflash tool it back to life... if I can get the drivers to cooperate...
Quick update on this... I found a tutorial on using adb and managed to sideload a rom, derp milestone 1 I believe it was, and after it completed the phone booted up just fine. My friend wanted it to be reverted back to its stock unrooted state, so I tried LG mobile something or other on my laptop... you all know, the one where you hit options then upgrade recovery and it should download and flash stick software? Well it saw the phone, and said there was no upgradeable software on it... mind you the phone still has a working twrp 2.6.3.3 on it... I don't know... I tried LG flash tool, but i can't get it to be port 41 for that to work... but at least the phone boots and runs fine now.
Still having my driver issue though. When I plug in the phone windows installs 3 drivers. One is CDC driver which always fails. No clue why.
Any ideas?
