Stuck at LG screen, won't boot

I am stuck at the original LG loading screen. I followed the instructions step by step and all seemed well and the device rebooted. I'm using Verizon G4 version 11a. But it never got past the original LG loading screen. I waited for a solid 10 minutes and still nothing.

I then tried to go back into the "Firmware Update" screen and resend the command but when I typed in "id", I'm greeted with "EXEC W ║º║╝#". I know I'm using the correct port so I'm not sure what to do now. Did I brick my phone? Should I try loading the stock firmware using the KDZ or TOT method? Any help would be appreciated. Thanks.

Sooooo... V10b-EUR-xx on my international H815 (norwegian, telenor)with no other ota available means that i can proceed with following the main thread, using the proper image from the op? Or does it mean i have to update using the flashtool before proceeding? I'm utterly confused...

edit: i found v10c in the build.prop and will root once i decided to actually keep the phone.
[G4 Q&A, Help & Troubleshooting] Deanos1:
Found a possible solution to my issue. I updated to version 2.20 verizon driver and changed COM settings to as directed in "TOT flash" instructions. This allowed me to run the LG mobile update program and gain communication through COM41 with the phone. The "unable to connect to server" error still displays in foreground, but the software update still loads in background as well as on the phone.

Unfortunately this flash has not fixed my original issue. I need to delete the Google Account information that was stored when the phone was originally purchased.

Phone is currently running VS986 11a
[G4 Q&A, Help & Troubleshooting] AvocadoBaby:
so did you flash in the end? Did the "adb.exe devices" command list your device as offline?
[G4 Q&A, Help & Troubleshooting] Deanos1:
I was able to flash with stock firmware, but it did not accomplish the goal I had. I am not using any ADB. The phone is not able to be put into a developer mode nor am I able to unlock the bootloader since I cannot access the settings menu.

Once there is a BL unlock, you will need to enable that to let adb access the bootloader.

Stuck on Step 6/7 (T-Mobile Variant)

Everything goes smoothly up until I get to 'download mode'. I'm noting this is a brand new LG G4 from T-Mobile with the right build number. I am attempting to root on the Windows 10 Operating System (if that makes a difference).

I get to download mode and it shows me the desired screen in step 7, but it stays at 0% for an indefinite time. I attempted to leave it on all night and when I awoke it was still at 0%.

My questions are:

Does the SIM card have to be present in the phone being rooted?

Does the computer doing the rooting need to be connected to Internet? I have hotspot but not an actual ISP.

If someone could help shed some light on this I'd greatly appreciate it. I would like to see my G4 rooted and using the apps I used on my G3. When I first looked for a method I was told the one I found was unstable and to wait for a solid one. I was told this one was. Thank you for reading and giving time to input.

Marmalade Shaws
[G4 Q&A, Help & Troubleshooting] Knowbody42:
It's not supposed to move from 0%.

What you're actually supposed to do is use the download mode to send commands to the phone, telling it to write a pre-rooted image (which you already copied to the phone) to the system partition, because those commands aren't going to work if it's booted into the full android OS (for a number of reasons).

No, and no.
[G4 Q&A, Help & Troubleshooting] Marmalade_Shaws:
Thanks, that worked. Though now I've messed up a bit and want to start the rooting process from scratch. I don't know how to get rid of the root; I've tried factory resets, uninstalling SU (which never uninstalls it just keeps saying 'please wait while it uninstalls' but it's like that for hours, and flashing the stock ROM onto the device. SuperUser is still there and root checker says my device is rooted.

The only reason I want to start from scratch with an unrooted device is because SuperUser keeps bugging me with something called "com.tmobile.pr.adapt" and I'm not sure what it is. After some digging it says it is a way for T-Mobile to tell if my phone is rooted along with a whole bunch of other info. I'd be content blocking it but rooting my LG G3 never presented this issue before. So I feel I've done something to warrant a redo. Unless you guys think otherwise could you point me to a successful unroot method? I've tired this one (http://xdaforums.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848) but I get stuck when it asks me to launch the tool and choose an appropriate dll file, both of which says they're wrong and no other dll files came with the download links in his instructions.

Do you guys know what to do?

Just deny/block that app and you shouldn't have any problems.

I've been getting stuck trying to root my Verizon G4 with 11a software. Everything appears to be running correctly when go follow the guides word for word however when I actually send the rooted system image (from vs96811a.tar.gz file) it takes maybe 2 minutes max. When I type LEAVE my phone gets stuck at the Verizon screen, the last time I left it there for about 20 minutes before giving up and flashing back to stock.

I've been using WinZip to extract the IMG file and the file I put on my phone (system.rooted.vs98611a.img) is only around 650 mb. Am I using the correct file? Could WinZip be causing the trouble? The only other thing I could think of is that it's an issue with the drivers on my desktop (Win7) but I tested on a different computer that I used to root my Razr Maxx with flawlessly and put fresh drivers there and ran into similar problems.

I've looked throughout the forum and couldn't find anything that directly related to my issue, if there is an answer already posted please point me in that direction. Otherwise I appreciate any assistance you guys can provide.

Thanks!

EDIT: NVM. Found the thread. lolll
[G4 Q&A, Help & Troubleshooting] RenaKunisaki:
Unfortunately there's no way to see the error messages in this shell.

The dd command should take a few minutes. It won't say or show anything, only return to the # prompt after.

If it returns to # instantly then probably you typed the wrong path for the img file, or possibly you have a bad cable. Make sure you used the right name in both the dd and adb commands.

The system.img file after unzipping should be just over 4GB. If you have a smaller file, probably the download got interrupted.
[G4 Q&A, Help & Troubleshooting] camatkāra:
Thanks for the reply. Yeah, it returns instantly to the # prompt. I just copied and pasted the commands, so that's not it. The uncompressed file is over 4.5G and I've downloaded several instances of it, so I'm pretty sure it's not the problem. The cable is new (came with the phone) and works to transfer files, etc., so that seems unlikely. Stumped right now. I'll try again tonight. All other ideas welcome! Thanks.

I rooted my at&t 10e and all was good until I decided to do a factory reset. Now when I go through the setup wizard it crashes at the very end then stars over again. Apps have been loaded because at one point SuperSU popped up for better battery stats. I had kept the rooted system on my phone but when I try to run the command to flash rooted image it just goes directly to the #. Any help would be appreciated.

Edit: when i flashed the rooted image I was on windows 8.1. Now I am on windows 10. Is this the reason that it goes instantly to the #? Or when I factory reset did my rooted image get erased. I didn't choose the option to erase media on SD card when I factory reset.

Edit edit: also I saw that this happened to a couple of other user. But both threads didn't give a definite answer to the problem. I am really hoping not to have to flash the 810pr kdz unless that is the only way. Is there a way to skip setup wizard? Can I push rooted image file to the phone since my previous rooted image file doesn't seem to be there?

Another note. I have factory reset using button combination multiple times. And I have tried the send command to flash the rooted system multiple times still nothing.
[G4 Q&A, Help & Troubleshooting] RenaKunisaki:
Just to be sure: you copied the correct commands? The img file is in the right place on the phone's internal storage (NOT your microSD card) and didn't somehow get corrupted there? When you enter id you get a response?
[G4 Q&A, Help & Troubleshooting] larrydp:
Is there a more preferred place to try downloading? I tried the links from the post, but I'll give it a shot again. Thanks for all the help!
[G4 Q&A, Help & Troubleshooting] camatkāra:
Thanks for the troubleshooting, but yeah, the commands were correct and the file was in the right folder. I doubt it got corrupted there because I went through all the steps several times, with about 3 or 4 different instances of that file. I can imagine one or two bad downloads/unzips/moves, but not 3 or 4. "id" returned the correct response. I'll run through it all again with a fresh instance of the file and post a screenshot.

[G4 Q&A, Help & Troubleshooting] camatkāra:
So running through the routine, again I get the same result, but now see that I can't post a screenshot as a new member. Oh well, the only unexpected output seems to be that the "id" command gives the right root ids but then ends with "context=u:r:recovery:s0". Since the instructions say that the output should "begin" with those root ids, I didn't think this was the problem (though I did google it without success). Is that the issue? Not sure what else to try at this point....

edit: After more digging around these forums, that "id" output is not the issue, either. Many people get it and still get root.

edit: thanks for your help, but I gave up and went with [MENTION=2522637]MicroMod777[/MENTION] 's One Click TWRP, which then gave me SuperSu root in a flash. Like many in that thread, I did however run into driver issues and I can't help but think that they were behind my issues here as well.

Yes you can delete once rooted.
[G4 Q&A, Help & Troubleshooting] Mohamadorabi:
So would it take 4Gb even after deleting it? Bcz the system size is 9gb... Will it become 13Gb at tgr end of thr process
[G4 Q&A, Help & Troubleshooting] RenaKunisaki:
No, rooting doesn't take up any extra space. You only need that 4GB file during the process; you can delete it after. It replaces the existing system partition, so no extra space used there.

However I do suggest to keep it as a backup if you plan to tweak things afterwards. If you delete some of the bundled bloatware, it will give a security error on boot, and you can restore from that copy to fix it.

---------- Post added at 14:58 ---------- Previous post was at 14:53 ----------

It's whatever the img file is named. If you downloaded it, use whatever name it came with. If you're rooting your own, use whatever name you want, just make sure it's the same both times and the path is correct.

Did you back it up to internal storage or external SD card? Most SD cards are formatted with FAT32 which has a 4GB maximum file size. Unfortunately there's no way to see the error messages from the download mode shell, so it won't give any indication if that happens.

Also check that you didn't run out of space and that you entered the command correctly.

It should be the same size as the one you flash, so something isn't right.

You should update to the latest version using a kdz file first, then root.

But as I just told someone else, personally I think you should be running the system that is meant for your specific version of G4.

There are more than one update paths. My Taiwan device is on 10C, which is the latest. Euro devices are up to 10F. But both these builds are the same as far as Android is concerned. They just have different carrier updates. So you should really use the one intended for your device.

10F and 10C are "the same" but for different versions of G4.
