Hey guys,,
i have a problem. i wanna root my phone via unrevoked and tried to install the HBOOT drivers. but when i plug in my phone the device manager doesn't name it as "Android 1.0" like it's shown in the tutorial, it is named "ADB". furthermore i can't install the hboot driver. any solutions?
The hboot drivers are installed when in hboot on the phone
so power down, power up holding the volume down and power.
Then device should show up as android device
ADB is when the phone is in debugging mode.
If you install "PdaNetA245_intl" this will install the ADB driver and you can cancel installation before installing the full application.
Unrevoked should then work

Thing is, i can't select "HBOOT" in this fastbootmenu
Turn the phone on holding the volume down button. This will boot you into HBOOT

ok I'll try.. just a moment
So now I am in this HBOOT-mode, where I have the options "Fastboot, recovery, clear storage, simlock".
but now my PC can't identify anymore. it seems... when I plug in my device , where HBOOT stands normally, turns into "HBOOT USB PLUG" but that returns to HBOOT very fast...
it worked after plugging it in for about the 10th time!!!
sooo.... now I rebooted the phone activated debugging and plugged it back in.. now it recognizes it again as ADB and wants to install a new driver and unrevoked can't find it... how to go on?!

Read my first reply. i have answered your previous question and this question, however it seems that you have just disregarded it.
ok rooting seemed to work now... but i tried to get a new rom on it.. so i followed the tutorial but couldn't find the ROM on my zip and when I want to reboot the phone it seemes to freeze @ the HTC bootscreen... i also tried with a wipe and booting again but it seems to totally freeze since i let it load for ~5 minutes now.

Did you perform a wipe? Wipes are vital to maintaining a functional ROM. Time could also depend on the size of the ROM you flash, so it could take a while. If you have been waiting for +20 min, try to go old fashioned and push a stock onto your sd. Or you could go even more old fashioned and take out the sdcard and put the ROM onto it. Make sure the ROM is not corrupt
Sorry to bring an old thread back up guys.
I'm having the exact same problem helping a friend root, could you provide a link for the program you did in your first post please as googling it returns those crappy host file sites that never work..
I presume that step is necessary?

I really hate to join under such a condition (it's an amazing site which I thought I would join for better reasons when time permitted), but my new Galaxy Nexus just went to hell on me after flashing the (apparently) popular Jelly Belly mod.
I started with a rooted 4.1.1 Jelly Bean OS with ClockworkMod Recovery, and now it looks like disaster after using that to flash Jelly Belly - what happens now is my phone boots up to the point where it flashes that colored Google "X", but it never proceeds beyond this point. I cannot put a different mod on my phone because there is no connection with my computer, and I can't stop my device from thrashing without a battery-pull. Is there any way save this phone and put plain Jelly Bean back on it?

When I do, I have that "Downloading..do not turn off the target!" message. Why this - I did remove the supersu file, although I think I left my clockworkmod file on the root because now you have to re-flash that every time you use it. Now I have no option other than "Start" - any chance of breaking through now?

thats not fastboot, thats odin mode. use vol up and down and power button to get to fastboot mode
the entire reason your phone is behaving the way it did is because you didnt wipe data/cache before flashing the rom.
you really need to do some reading before you start modifying your phone

Do you mean that I need to continually rock the Volume key up and down while holding the Power button? Volume Up with Power put it in boot mode, and when I tried rocking it a couple of times I got the same result. It I understand you correctly, the idea sounds tricky. Is this supposed to work on a Galaxy Nexus?
press and hold both ends of the volume button and the power button... its really not that hard.

What I really should have done was slow down, or quit while I was ahead to get some rest last night! I had researched the root process for my phone ad nauseum, which I know is why I succeeded at getting ClockworkMod safely installed. By the time that was done I was tired, but I counldn't stand the thought of living without my files loaded on my phone - I was in the bad state of needing too much to complete what I had intended to do. I see I had the wrong impression that ClockworkMod would take care of the whole process once I had that working, guess it didn't. When you've been through the process of installing a hundred versions of Windows and Linux on a PC, which never needs to be pre-wiped (the new OS does that), who would have thunk it's that much different with a phone computer?
Did you get this solved? Just reboot into recovery (hold down power, volume-up, and volume-down simultaneously to get into bootloader, choose recovery using volume buttons, select using power button), full wipe (system, data, cache), and reflash your ROM.

This is another thing I never would have guessed without being told specifically, that it's even possible to hold down both ends of a rocker switch and have it do a different function - I tried this, and now it works! I had used my PC to root my phone last night, and right now I'm at work, where there will be time to go through this in a couple of hours. I took a brief look at the tutorial recommended by Zepius, and am wondering if I am set to proceed. I plan on using my work PC, not the one at home with the drivers I used to root my phone. Nobody else uses it and I have never used it for anything phone-related. Can I presume any drivers which I'm warned should be uninstalled would be on the PC which is used, and not the phone?

Sorry, I had to work, but now there's time and I thought I would try my work PC, which is virgin (so to speak) of mobile devices and drivers. It's a Windows XP system, and right now it's not looking good because when my phone is plugged in, there isn't a "Portable Devices" or "Mobile" category under Device Manager. Do I have a better chance of this working on my home Windows 7 system?

I guess that's a never-mind, I should have had my phone on! It's in Fastboot mode now, but I still don't know if what I see in Device Manager is good for what I'm trying to do. No portable device, phone, nor galaxy nexus, but what did change is I have "Broadcom Nextreme 57xx Gigabit Controller" appearing under "Network Adapters". Is this a problem to be dealt with differently when your phone is bricked?

1) your phone is not bricked. dont call it that
2) best way to check if your drivers are installed correctly
open a command prompt in the folder where your fastboot.exe is and type: fastboot devices
if you get a device ID, your drivers are setup properly for fastboot
3) at this point, just return to stock: http://forum.xda-developers.com/showthread.php?t=1626895

I got a device ID (long string of characters) on that fastboot command, but I'm still concerned that my phone won't talk to Device Manager at all. Windows 7 doesn't pop up a connection window when it's plugged in, should that be expected?
What I mean by "not talking to Device Manager" is that the only item under Portable devices is just E:\ - no device listed here! The tutorial in your signature hinges on there being a device listed "without thde yellow exclamation point", for the installation of new drivers, therefore I don't know how to follow it from here. The adk drivers which were used to root my phone (they were good, the problem began when I tried to flash a rom and missed a step or three) are stil there, but I'll replace them if I can find a process which can talk to my phone in it's present state.
On a side note (and only because it held me up in responding tonight from my Windows system), is this site partial to Firefox? I am able for the first time to login, and I wonder if it isn't because I quit trying to through my Windows 7 system. It has only Windows IE, and Chrome (which couldn't even browse this site). I am currently on my Ubuntu system with Firefox.
good lord... you have a device ID so just use the fastboot commands... start at part D

I said much the same myself.
For the fastboot devices test, I have a string of characters, but no device name, only "fastboot" on the single output line with those characters. Is this a valid device ID?
"...just use fastboot" Ok, but how? Should (can I) even do this use fastboot to transfer files to my phone under it's somewhat anonymous status with Windows? Since last night's fiasco nothing was named under "Portable Devices", only "E:\" was displayed. I have no graphical display in the file manager, so how am I supposed to transfer the necessary files to the root of my phone? I don't even see a way of addressing it to install drivers now.
I will need drivers because I attempted to follow this tutorial (which doesn't account for what I am (not) seeing on my system. I got as far as uninstalling the good drivers which I used last night in favor of what was offered for use with the tutorial, and now Device Manager doesn't even have a Portable Devices category. The "Universal Naked Driver" was to replace my uninstalled drivers, and interestingly the contents of it's expanded folders don't even contain fastboot (the adb package which I used last night did). In light of this, how am I supposed to have even fastboot?
I hate to be a PIA about this, but I guess I'm more a n00b than was presumed in this tutorial - it's either that or my situation really is too different that I can use it as is. Could I please get a few clues in light of what the tutorial doesn't address? Do I have any means of installing anything and transferring files with my device-PC communications as they are, and if so how can I do it? I'll give it a run if I understand how.
Thanks.

I see now that Part D calls for flashing JO03C from my PC, not the device root, ok.
Also, after rebooting my laptop, the E:\ is back under Portable Devices in Device Manager. When I double-click this I get the statement
Device: Portable Devices
Manufacturer: Generic-
Location: on UMBus Enumerator
I don't think this looks better than the Microsoft default, but is it good enough for what I need to do?
I still have the driver package android-sdk-windows, which contains adb and fastboot, so perhaps I should just use this according to Part D and see what happens?

Good god, I never should have read Zepius's tutorial - I didn't need my PC at all! If I understood what bananagranola had said, I could have saved a lot of time!
Oh, no, now I can't connect with the server!
Could I have possibly lost my radio from what I did earlier? I was able to boot up, and I was upgraded to 4.2.1 when I did the data wipe. Starting over, I should have had a prompt to connect with gmail and download my contacts, but this didn't happen. My People app is unpopulated, so I chose to connect to "sign into an account". While I am sure of my login input, it didn't recognize this, and then the process ended with a "couldn't finish - couldn't open connection with the server" error. Any clue where to go from here?
Some standard apps are missing too, including the Play Store app!
Hi guys, I'm trying to install RomAur onto my device http://forum.xda-developers.com/showthread.php?t=2641067.
1st step is to root the device ON LOCKED BOOTLOADER which leads me to http://forum.xda-developers.com/showthread.php?t=2634196.
And from that thread I've followed the instructions, placed my 2 .ftf files in the firmwares folder within Flashtool.
At which point I've run into 2 problems. 1st, the Z1c isn't recognised by the tool. So I tried to tell the program that it's just a Z1.
Next problem occurs when I try to flash the device, my specific firmware doesn't show up in the Firmware Selector. The only thing showing is X10 V1 BLRelock, which was already there by default.
Could someone give more detailed instructions as to how to flash using Flashtool please.
If you want to unlock the bootloader make sure to back up TA partition!
Check out my guide, it's more detailed: http://forum.xda-developers.com/showthread.php?p=50176658 (rooting is the same process as Darkimmortal's guide)
See step 8, you probably didn't put the ftf file in the correct folder.

Thanks for replying.
I can't seem to manually update the z1c drivers, device manager keeps telling me i have the latest driver. So I skip that step and carry on.
Stuck at 8. I've tried putting the ftf in /firmware as well as other locations and changing the directory that flashtool will search.
Something else is wrong, any other suggestions?

You can see the source folder in the top of the Firmware Selector. Default is "C:\Flashtool\firmwares". Make sure your file is inside there and ends with ftf.
Also check if the file has the correct hash:

Make sure your phone is off (hold volume up and power button 5seconds, if the phone was on it will vibrate 3times and shut down).
Then power on your phone normally (hold power button until there is a slight vibrate). The screen will stay black, this is normal.
Plug in the USB cable to your pc and continue with step 13.
If it still says 'Waiting for device' you either:
a) don't have the drivers installed (check in device manager if something shows up when the phone is connected)
b) didn't correctly execute step 10
c) selected some wrong options in step 11
If it's b) or c), best solution is to start from scratch.

Ok so I managed to sort it out by starting from scratch.
I think it would be helpful to mention in your guide that the phone is blank from steps 13 through to 15. Thanks for the help, appreciate it.
Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2
I am not experience in rooting Android machine, this was my first time and unsuccessful. My device is now could not be started up.
The following is all information I summarized for this exercise, and would like to seek all advice on the followings.
--1 Is my device "recoverable" if yes, how and what do I need to do please?
--2/ or is it definitely "bricked" so I have no chance to recover it at all.
I am totally in-familiar with rooting machine and I have no access to Linux machine.
Any advice is welcome.
Thx in advance.

2/ Click "Unlock", pressed "Y" to proceed. - Device went into a screen asking me to select and confirm, I used the "Vol +" to select "yes" and pressed "power" to confirm, but nothing happened on both computer and device after the "power" switch was pressed. Instead, it freeze the device. nothing is responding even after 10 minutes.
3/ I have pressed the "power button again for 5 sec. and device shutdown to black screen.
4/ Since then, every time I try to start the device, the machine first show a "Google" , then a "rotating flower pattern" and won't started. i.e. - "the flower pattern" keeps looping.
5/ on the computer side, no matter what command is given in Nexus Root Toolkit, a notification of ADB device was not found error comes up.
Consequence
A) Device can be switched on and off by pressing "power" button. when switch on, it display "Google" , then a rotating flower pattern, and never end.
Switch the power button for 5 sec again, device switch off.
B) When device is off, press 'power' and "vol -" will switch on the device to a menu with a robot lay down, options "Restart bootloader", "Recovery mode", "Power off" and "Start" can be selected.
C) For "restart bootloader" the screen goes black for 2 sec, then the menu appear again with "Start" option. i.e.- no error no message
D) For "Start " - the device just just act like normal start, end up in a looping rotating flower pattern.
E) For " Recovery mode" - device screen goes black for 3 sec. show "Google" then show a dead robot with an exclamation mark on it, message " No command" is showing. - After awhile, device restarted and end up in the rotating flower pattern.
F) When plugged in, Window 7 can detect the device, when teh device is in the menu, "Android Bootloader Interface" is shown in Windows Device manager, when the device is starting, " Nexus 7" is detected in Windows Device manager but not both.Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2

Step 1 to Step 4, install the drivers on the computer. and "Full Driver Test" passed
2/ Click "Unlock", pressed "Y" to proceed. - Device went into a screen asking me to select and confirm, I used the "Vol +" to select "yes" and pressed "power" to confirm, but nothing happened on both computer and device after the "power" switch was pressed. Instead, it freeze the device. nothing is responding even after 10 minutes.
3/ I have pressed the "power button again for 5 sec. and device shutdown to black screen.
4/ Since then, every time I try to start the device, the machine first show a "Google" , then a "rotating flower pattern" and won't started. i.e. - "the flower pattern" keeps looping.
5/ on the computer side, no matter what command is given in Nexus Root Toolkit, a notification of ADB device was not found error comes up.
Consequence
A) Device can be switched on and off by pressing "power" button. when switch on, it display "Google" , then a rotating flower pattern, and never end.
Switch the power button for 5 sec again, device switch off.
B) When device is off, press 'power' and "vol -" will switch on the device to a menu with a robot lay down, options "Restart bootloader", "Recovery mode", "Power off" and "Start" can be selected.
C) For "restart bootloader" the screen goes black for 2 sec, then the menu appear again with "Start" option. i.e.- no error no message
D) For "Start " - the device just just act like normal start, end up in a looping rotating flower pattern.
E) For " Recovery mode" - device screen goes black for 3 sec. show "Google" then show a dead robot with an exclamation mark on it, message " No command" is showing. - After awhile, device restarted and end up in the rotating flower pattern.
F) When plugged in, Window 7 can detect the device, when teh device is in the menu, "Android Bootloader Interface" is shown in Windows Device manager, when the device is starting, " Nexus 7" is detected in Windows Device manager but not both.Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2
I am not experience in rooting Android machine, this was my first time and unsuccessful. My device is now could not be started up.
The following is all information I summarized for this exercise, and would like to seek all advice on the followings.
--1 Is my device "recoverable" if yes, how and what do I need to do please?
--2/ or is it definitely "bricked" so I have no chance to recover it at all.
I am totally in-familiar with rooting machine and I have no access to Linux machine.
Any advice is welcome.
Thx in advance.

I'll take up the task to help you. You are not bricked. You are stuck in something called a bootloop, which is basically when the device enters the boot sequence, but never finishes. The flower pattern that you are looking at us called the boot animation. The computer never recoginizes the tablet through ADB because the tablet never gets to that point.
The screen with the Android laying on his back is actually the bootloader itself. That's why restarting the bootloader brings you to the same screen. I actually want you to be in the bootloader screen. You already have the Nexus 7.2 drivers, so you're ahead of the game.
You also need to visit here to download TWRP 2.7. You also need to put the file in the same directory as the fastboot and adb files.
You need to boot into the bootloader, and run the command:
fastboot flash recovery <recoveryname>.img
This should get TWRP onto your device. You can then download a rom of your choice to put on the tablet. Since you will not have access to place files on the device through USB, you will have to sideload it. First, let's get recovery working, then come back to me if you need help sideloading the rom through ADB while in recovery.
Dear aarsyl,
Thx for your help and it is much better to know my device is not "bricked". Thx again!
Thx for your detailed explaination and I feel much better by knowing a little bit more on what is going on.
>>>>You also need to visit here to download TWRP 2.7. You also need to put the file in the same directory as the fastboot and adb files.
[I also found it in my computer already .\WugFresh Development\data\Recovery_Custom\TWRP
but I downlaod it again from your link and put this file in the same directory where I find the fastboot.exe and adb.exe, which in my case is .\WugFresh Development\data\ ------ done.]
>>>>You need to boot into the bootloader, and run the command:
[- I supose you refer to my Nexus 7, so I will switch it on with the "power button + vol -" button. and get it into the bootloader.]
>>>>fastboot flash recovery <recoveryname>.img
[Here I got an query, what image file I need to use? is it the <openrecovery-twrp-2.7.0.0-flo> ? Do I neeed to run it as an adminstartor in Window 7?
so, do u mean I need to type: fastboot flash recovery openrecovery-twrp-2.7.0.0-flo.img ?
is it right?--(A)
if not, then I am not sure what recovery file to be used!
I do not have any other img file in package I downloaded previously

Not quite understand it this bit, but as you say. it can wait later.
So assume I do the "fastboot flash recovery <recoveryname>.img and get the TWRP on the Nexus 7.
What do I expect to see from the nexus screen. Does it have any note saying completed, or shuold I expect a reboot of the Nexus.
I think one of the problem dealing with these kind of thing is lack of acknowledgment fromt eh machine so we do not know if the operation is successful or not.

I decided to have a go with the downloaded twrp img file.
I launched the command " fastboot flash recovery openrecovery-twrp-2.7.0.0-flo.img" from a command window as an adminstrator.
The command failed with an error saying (remote: Bootloader is locked)
And when I check the Nexus 7 screen, it does said "Locked Status - locked" in the last line.
photo showing both the computer and teh Nexus 7 screen.
Oh, I hadn't realized that you were still locked. No wonder you're not getting anywhere.
Reboot into the bootloader, and run:
fastboot oem unlock
Follow the screen instructions to unlock the bootloader, then run the command to flash the recovery. I advise changing the recovery name to something shorter and simpler, like twrp27flo.img, for example.

Hi, Nice to have reply from you again.
Ammm. I switch on the device to the bootloader alright. run teh command "fastboot oem unlock"
On teh command window, it said" < waiting for device>
and there is no visible change on the device screen.
It already last for 10 minutes now.
I do noted that both windows are freezed and do not respond to key press and button press respectively. No responds on both the device and computer.
How lond does this process take to show the mentioned "screen instruction"? I don't see one!

wow.. it is unlocked now!
Should I continue to use the "fastboot recover command with TWRP file" as per your advise or should I continue to use the "Root" command in NexusRoot Toolkit ??
It is very happy to see there is progress.. Thx...
please keep coming...
I would go with using fastboot to install TWRP. In truth, to truly "root" your device, you actually need a working rom on the device. Otherwise, rooting will be in vain. Unlocking the device was the most important.

Hi again,
Yes. my device is now boot up as brand new.
One side observation though, every time I issue command through window 7 in a command window, everything will freeze up, (not remember if I unplugged the device) until I press the power button to restart the Nexus 7. Same for the last time when i did the unlock and this time recovery.
The hesitation was how do I know when to do this, was worrying there is still some communication between the two machines if I unplug or interfer, may just disturb the communication and corrupt files. -- I normally give it some 10 minutes before I do the unplug and restart. any comment or advice?
Anyway, the device is now up and running. What is the status now? is it with the original version of software? or TWRP version or what?
The device is now remain "unlocked" - is it ok or I need to lock it again?
You have mentioned to download a "Rom", what about it, it is only need if i want to continue to "root " the device?
Sorry for so much question.
I am so happy to see it comes alive again but really would like to understand the current status of it.
Thank again. aarsyl
To be honest, I'm not entirely sure what the status of your device is right now. I was under the implication that you had no Rom on the device. Since you are trying to root for the first time, then yes, you are on the stock software that comes with the device. If you search your app drawer and find the SuperSU app, then you are already rooted, my friend. If it is not there, then search for SuperSU 1.94 in Google, and download the zip file. Then reboot into recovery and flash it.
In other news, I am happy that you got your device working, and I am more than happy to help. The only thing that I don't do is recommend roms. I encourage users to explore different roms for themelves.

I'm sorry for the long delay. I got locked out trying to log in after I changed my username twice, and it just got messy for me. At any rate....the SuperSU zip file is to be flashed through recovery. When you boot into recovery, select Install, then navigate through the device to find the folder that the file is located. Follow the screen directions to flash items.
USB Debugging needs to be checked for ADB to work, so.....yeah....leave it on.
You don't have to relock your device unless you have to bring it back to the store for repairs. It only stops you from making changes in the bootloader, such as flashing new recoveries, and I think that most fastboot commands might be blocked. I have never tried to use fastboot on a locked device, so I really don't know. Leaving the device unlocked doesn't make it vulnerable or anything, at least to my knowledge.

Thx for your advices AarSyl,
I have successfully root the device and get the Super user app running by following one of tutorial video.
For the first time, when I start at teh bootloader and conduct a "Recovery", it shows a dead robot again but without "no command". I have to redo the fastboot command in the command window with the TWRP recovery file once again. (but this time is very smooth no need to unplug cable that sorts of thing) then I get into the TWRP menu after "Recovery".

Great. I'm happy that it is working for you. A little tip...download Quick Boot from the Play Store. With one touch, you can power off, boot into the bootloader, boot into recovery, or reboot Android.
After downloading the new AT&T update yesterday my phone (No root) went thru the update process and completed and then restarted itself and ever since then has been stuck in a boot loop on the LG logo screen. Was going to do the flashing procedure but when I try to boot the phone in download mode the little box appears saying "download mode" but instead of the "firmware update" screen appearing shortly after that my screen just goes black again. Have tried every port using the stock chord on my computer (Windows 8.1, USB 3.0) and have tried every port on another computer (Windows 7, USB 2.0) and still the same thing every time. Have installed the proper LG drivers on both computers but still fails to recognize the phone correctly under device manager as well.
ANY HELP IS MUCH APPRECIATED!
Update to lollipop? Wow sorry to hear that OP. Did you pull out the battery? Sometimes that helps strangely.

Update to lolipop went fine it was this update that enables VoLTE that screwed it up. I cant post link because I am a new member but google it and you will find it.
But yes pulled the battery out first to end the boot loop and thats where the original post picks up from.
Sometimes to get into Download Mode:
Remove Battery.
Press Volume Up.
While still pressing Volume Up, replace Battery.
Still pressing Volume Up, connect to p.c. by USB Cable. Phone should now enter Download Mode......

Before I even start just gonna let you know you have to flash the phone back to the stock firmware meaning you will lose anything saved on your phone but this is the only way to get it back functional.
Pre-requirements
1. Stock LG cord that came with phone
2. Desktop computer with USB 2.0 ports (3.0 wouldnt work for me)
3. Disable driver signature enforcement (Depends on OS as to how to do this so just google it. Takes just a few minutes)
*UNPLUG PHONE BEFORE STARTING*
1. Download and install the QDLoader HS-USB Driver here: http://www.androidbrick.com/download/qdloader-hs-usb-driver/
2. Plug your phone in while holding volume up to initiate "Download Mode" and it should now show up under "Ports" as "Qualcomm HS-USB QDLoader 9008"
3. Download and extract this: https://www.drive.google.com/file/d/0B_Hol5T47S-bYjNETmVPZkdWUms/view
4. Now download the stock fimware files (the .zip and .dll files) here: http://downloadandroidfiles.org/directory-php/?Directory=/LG%20G3/Stock%20Files/ATT%20D850
5. Extract the .tot file out of the .zip file and place it and your .dll file on your desktop.
6. Now open (be sure to right click and run as administrator!) BoardDiag which is located in the BoardDiag_V2_9 folder you downloaded in step 3.
7. If you need pictures to follow along with the next few steps go here: http://forum.xda-developers.com/lg-g2/general/tool-unbrick-lg-g2-qualcomm-9008-board-t3072073 and see the Attached Thumbnails at the bottom of the first post.
7. At the bottom under "Image Extraction" place the .tot file in the BIN field and make the DIR wherever you wish the files to be extracted to and then hit "Extract" and wait for process to finish.
8. Now under "Board Diag Test" check the boxes beside "AP check" and "EMMC TEST"
9. In the right column make sure "B2 (MSM8974AC)" is selected in dropdown "AP Chipset"
10. On the "Com Port" dropdown select the COM number your device shows up with in Device Manager.
11. In the "Target Dir" type the destination where you extracted the .tot file to in Step 7.
12. Click "START" and wait for process to finish. If the test passes the AP check and the EMMC TEST then you're good to go. If not then im afraid you have a hard brick and I cant help you there.
13. Uncheck "EMMC TEST" and check "RESTORE BOOT IMG" under "Restore Device"
14. In the dropdown beside "RESTORE BOOT IMG" choose the following in the order typed and hit "START" after choosing each file letting it flash the stock file to your phone: aboot--Backupgpt--boot--dbi--laf--Primarygpt--recovery--rpm--tz--sbl1
15. Your phone should now have the LG logo and underneath that say "Security Error".
16. Unplug your phone and pop your battery out and back in. Now plug your phone in while holding volume up for "Download Mode" and this time it should display the "Firmware Update" screen after a few seconds.
17. Now that you have the Firmware screen this guide will help you get your phone software back up and going (THIS IS WHERE YOU NEED A USB 2.0 PORT): http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html
Good Luck!!
Imporatant: If the OTA update boot looped your phone like mine DO NOT apply any OTA updates your phone tells you to apply because the same thing will happen again (Trust me I tried it)
craincrizzy, much thanks. Well written. I finally got the phone up. Good to be back in business. Thank you a million times again!
Good to hear. Glad I could help.
