I did the KDZ method for 20B. How can I absolutely make sure that the phone isn't rooted? I might need to send it back or at least bring it to a TMO store and try a new SIM. I know with Verizon versions, there's a setting in software that says Software Status: Official. Is there a setting like that on this phone or is there a different way to find out?
[T-Mobile LG G3] hyelton:
If you flashed a kdz there's no way your phone can be rooted anymore.
[T-Mobile LG G3] sefirosu0522:
Thanks! I appreciate it.

Help

can someone please help me i have an lg g3 d851 (tmobile). i just got this phone like 3 weeks ago and rooted it..i think i used lg one click root . about a week ago i started having problems with my wifi where some apps would connect and work fine but other apps would not connect. i decided to factory reset (since i didn't have anything on the phone anyway) and when it booted back up i went through the setup process and at the last screen it fails and says "Unfortunately LGsetupwizard has stopped working." and it takes me back to the first screen. I have no idea what to do should i take it to tmobile will they fix it or should i try one of the methods above? if so which method should i do?
[T-Mobile LG G3] ThePagel:
Read the directions and pick which one is best for you, since You didn't know what twrp was when you pm'd me don't even bother reading it. Use the tot or kdz, the end of the tot is different than what is described but if you read the on screen prompt you'll figure it out.
[T-Mobile LG G3] matty1323:
It's weird because I must have gotten lucky when I went through this process before and had no issues, went to return to stock a 2nd time as i'm going to trade in my phone with my carrier and need to un-root it and it would fail on the 6% saying "Can't change to download mode" as well. I found out it is in fact due to the USB 3.0 port i'm using on my laptop vs the usb 2.0 hub I used before and tried again today and it worked fine. It doesn't look like usb 3.0 ports will allow this process to complete successfully. Everything looks fine until you start the process through the flash tool, Good to know!! I was really frustrated for a minute there.
[T-Mobile LG G3] hyelton:
Yeah you MUST use a usb2.0 port.

I am stock rooted on lollipop . need to send phone as JUMP. which method should i use ?
[T-Mobile LG G3] vel0city:
Well if you have TWRP installed use that method to flash back to stock. If not use the KDZ method which is just as easy.
[T-Mobile LG G3] hodgestl:
cant't downgrade

So I have a D851 that was upgraded to 20b. Are you saying that even if I do the KDZ for 10r back to pure stock without root or recovery, I will still have connection problems since I have in fact had LP 20b on my phone? Boy I hope not. That would be horrible. Thank you in advance for any advice.
[T-Mobile LG G3] msarnowski:
So I'm having a bit of trouble. Basically the tool stalls at 60% (I tried both methods of flash). The driver package you posted doesn't seem to work on my computer but I found another 3.11.3 to download. The thing is that when I download the file lgunitedmobiledriver_S50...3.11.3.exe it will show up as lgunitedmobiledriverS51...3.12.3. But when I go to device manager I have multiple things pop up and all the versions are 3.11.0. Also, my LGE android MTP device driver seems to fail to load, which seems to be stalling the flashtool.

Please help! Can someone verify the drivers posted are working/post another link if not

---------- Post added at 04:49 PM ---------- Previous post was at 04:13 PM ----------

So I confirmed from LG that the 3.12.3 drivers are the newest for this phone. The problem I have is that LGE Android MTP Device driver is failing to load. All other drivers load when phone is plugged in except this (btw it says I'm on usb seial port COM4, I thought I read somewhere it should be COM41?? Not sure if this is an issue)

The Flashtool will recognize my device but as soon as the S/W download starts the MTP driver fails and everything stops. I can't find a MTP driver to download.
[T-Mobile LG G3] ThePagel:
What version of windows are you on? This will not work on xp or older. If you are on vists or later try to download microsoft c++ runtimes and try again. Ill make sure I post the runtimes installer in the op tonight.

You might need to try it on a different pc or fresh install of windows. Or make sure there are no non windows processes running before you start the flash tool.
[T-Mobile LG G3] msarnowski:
Win 7 64bit. I got it to work but by using a different TOT method

http://xdaforums.com/showthread.php?t=2432476

For some reason my comp didn't want to play nice with the drivers. With the alternative TOT method I was able to work around this issue. Your write up is very nice and I prefer your level of clarity in your tutorial.
[T-Mobile LG G3] dems86:
Edit. Just checked....

It is currently rooted with the full purpledrake method (i just used the bnr recovery method before widows script was out, this time boot.img was flashed) and it was definitely tripped before I flashed to stock yesterday.
[T-Mobile LG G3] ThePagel:
Happy to hear you have it working and thank you for the compliment:)
[T-Mobile LG G3] saco274:
What do you mean when you say uncompress the KDZ file?
[T-Mobile LG G3] ThePagel:
Its compressed in 7z ill make that more clear in the op.
[T-Mobile LG G3] saco274:
You do mean extract correct? Also I'm not sure if I'm doing this correctly but I'm trying to get into download mode and I think I'm in but the screen says "Firmware Update" and it's on 0%. On the bottom of the screen it says user B99 but its doing nothing. Plugged in for a few minutes now and nothing. Am i missing something?

On windows 8.1
[T-Mobile LG G3] ThePagel:
That all sounds right to me. I'm not trying to be a **** but it does say extract in the op.
[T-Mobile LG G3] saco274:
Sorry I must have missed it. I'm coming from the Note 3 so it's a little different. I'll try again.
[T-Mobile LG G3] ThePagel:
I hear you Odin is much easier. This program works one moment then seems to be broken the next. The other day I I used this and the program was saying there was errors but the phone % continued to increase and had a successful flash.
[T-Mobile LG G3] PlatinumNick:
Recovery

Does this firmware include the stock recovery on there? I have twrp recovery and im wondering if i flash this would it remove it or keep it on there?

Thanks
[T-Mobile LG G3] Mikey:
(Back to original untouched stock)

Last time i checked, custom recoveries are not to be considered to be STOCK ;)
[T-Mobile LG G3] mcme21:
Awesome Post

Thanks to all the devs around XDA. Always got the most useful info. Long time stalker around here and just got my G3, looking forward to what is in store.
[T-Mobile LG G3] mr pnut:
The way i go back to stock is using lgmobile support tool no kdz files needed :) if you have lg mobile support tools on your pc just open that up then plug in your phone not in dl mode one its plugged in choose option from the support tools and choose update recovery that's it let it do its job. After that your phone would be back to bone stock.
[T-Mobile LG G3] ThePagel:
You can't edit your build number or recover from a near brick experience with that can you?

I noticed that my Windows 8.1 PC would give me an error saying that it failed to enter download mode. I attempted to use usb 2.0 slots but to no avail.

Only after moving to a windows 7 PC did I successfully flash to stock. It's worth noting just in case people get errors I think.
[T-Mobile LG G3] vel0city:
Pretty much man, only way to go back to KK and have stable connection is having that efs backup from the beginning, but even then that is not a 100 percent guaranteed sometimes for a solid stable connection.
[T-Mobile LG G3] ThePagel:
Yeah, the only way to have good connection on anything other than lollipop now is to kdz back to kit kat and restore a kitkat EFS backup. If you don't have that EFS backup from before the update you won't be able to properly down grade.

Oops didn't see that you already got the answer
[T-Mobile LG G3] hodgestl:
:(

Thanks for the reply. Boy that is bad news. I have just had the D851 for about 3 weeks but it already had LP 20b on it when I got it. I need wifi calling to be stable, and its not on LP 20b. So that is why I was trying to downgrade. I guess I am stuck till T-Mo comes out with their fix. Thank you very much.

Any way to get a copy of that EFS file? or create it?
[T-Mobile LG G3] ThePagel:
No because it has the imei inside. I'm not saying it's impossible but it would require you to change the imei in the efs to your number, that's walking a line xda doesn't want you to be even close to.
[T-Mobile LG G3] hodgestl:
Hey I have done a little digging. I just got my G3 D851 phone on May 8, but 20b had come out back in April. I bought the phone on Swappa from the original owner. He upgraded to LP 20b. Anyway, I have found 2 files on my phone that are dated March 4 of this year. One file is /system/bin/efsks and is 11.83 kb in size. The other file is /system/etc/init.qcom.efs.sync.sh and that file is 1.68 kb. Is there any chance that either of these files is or contains the EFS info that I need to downgrade back to KK? Just wondering? Thank you
[T-Mobile LG G3] Kaflex:
Thanks OP!!!!!!!!! I needed to get my phone back to stock to send back and this is the only thing that worked, I tried other guides and nothing worked. :highfive::highfive:
[T-Mobile LG G3] Zaiaku:
Got a new LG G3. It had LP on it. Don't get me wrong LP is nice but too many problems for me since I use XPosed Framework. After installing TWRP, I flash stocc KK rom (debloated & rooted) and had serious connectivity problems. then I saw this thread and was heart broken. I decided to go ahead and use the LG Flash tool to flash Stocc KK from a TOT file. Everything running fine now and I'm back on KK. This may help someone in the future.
[T-Mobile LG G3] bertcarv:
So there is no way to get this phone to work again? I also mistakenly downgraded and now have connection problems. Any help is appreciated. If not I'll be stuck with a paperweight here. Thanks again..

Bert
[T-Mobile LG G3] ThePagel:
Go back to L and do a factory reset after. Your network connection should be fine after that and Tmobile has to be close to fixing the few problems with the rerelease of L.
[T-Mobile LG G3] bertcarv:
Thank you Sir. Will try this right away. Sure hope it works, this Iphone 6 Plus is KILLING me!..lol Thanks

Bert
[T-Mobile LG G3] bertcarv:
Okay so I followed what you mentioned above. I'm able to place a phone call just can"t get data to work. Any ideas? Maybe flash a modem? I can make calls but have no mobile data working.

Thanks.

Okay an update... I see 4G when receiving a call but not LTE. I set up the apn for LTE though. Any help is much appreciated.

I'm even able to send texts. But when I go to set up an email account is says I dont have a data connection?

Thanks again.

Bert
[T-Mobile LG G3] bertcarv:
Would you be able to provide the needed files or point the way to whee theyre at please? I downgraded and now when I came back to LP I can't get data connection or the LTE signal to stick. The only time I get 4G LTE showing is when I get a phone call. Then afterwards it goes away again.

Thanks.

Bert
[T-Mobile LG G3] bertcarv:
Okay so I went to the OP and downloaded the twrp file lp 20b untouched. I followed the directions exactly. Now when phone boot up I'm inundated with force closes, ui crashes etc... Very frustrating to say the least. I'm trying to get my data connection to stick and my 4g LTE to stick as well. Anyone able to lend a hand or suggest something different? I appreciate the help.

Thank you,

Okay so I wiped all caches oncenagain and got it to boot. No force closes but lost my navigation buttons? Crazy stuff man.

Bert
[T-Mobile LG G3] vel0city:
Factory reset from TWRP and that fixes the no Navigation buttons. For LTE sticking here is the fix, just follow my instructions and you should be set.

Bert
[T-Mobile LG G3] vel0city:
Factory reset should fix that issue, if not restore back to stock via KDZ.
[T-Mobile LG G3] bertcarv:
I still can't seem to get mobile data for some reason. LTE setting is sticking in mobile setup but it doesn't show until someone actually calls me and then when the call is ended it disappears again.

Okay so here's an update in case it works it may help someone else. Not sure how to explain other than I called my number from another phone. I stayed on the line for over 5 minutes and while I was on the line the 4G LTE symbol appeared and I went ahead and checked data connection. Everything showed fine. I surfed the net and after five minutes I hung up and the connection is still there. I havent wanted to reboot for fear id lose it but I know Ill have to at some point to check. I'll continue to update you. Thanks again.

Bert
[T-Mobile LG G3] ThePagel:
It's awesome you have data again. This problem is a good example why I am not going to be buying another lg phone. No reason why a update should have such different results for so many people also no reason why downgrading the firmware on a unlocked bootloader shouldn't work like it did before the update. Some night blame tmobile but its lg that makes the firmware.
[T-Mobile LG G3] bertcarv:
Yes, and as a follow up the data and LTE appear to be fine overnight and into this morning. Now, I haven't turned the phone off or turned data off and on again. I'll wait until I'm home later this evening just in case. But hopefully it stays put. It was a close one for sure. I thought I'd have to "deep six" the phone yesterday!..lol

Thanks again for all your help.

Hey, I need help please! I flashed the D85110R using TWRP. Everything went fine but now I don't get service. My phone says I have an "Invalid SIM" and I don't receive any upgrade, I'm stuck on 4.4.2. I want to upgrade my phone(I don't use JUMP). Will it be fine to upgrade my phone like this? I'd still like help fixing this problem please. And do you receive a new SIM when you upgrade? Thanks in advanced.
[T-Mobile LG G3] ThePagel:
I see you already got your answer in another thread, it's important to read everything in original posts and research if people are having problems before you attempt to do anything. A handfull of people including myself didnt have problems on 5.0 but it seems the majority of people do. I stated in the op if you upgrade to 5.0 you will not be able to properly downgrade.

*Edit* oh and your not getting upgrade notifications because tmobile has suspended the 5.0 rollout until bugs are worked out. Even when they do start rolling out again you may not get the notification because your efs has been changed by the L upgrade. Chances are you will need to manually flash 20B v2 (probably won't be 20b it will be 20c or something) when it comes out, after that ota's should work again.
[T-Mobile LG G3] Tech_Savvy:
i was wondering what the difference is if i use kdz to return to stock to prepare for a warrenty return...doesn't kdz return phone to 100% stock? i have the kdz file downloaded as the reason why i, asking if it's good enough...thank you
[T-Mobile LG G3] ThePagel:
Yeah it's good enough if the kdz program works for you. But it will not revert the changes in the efs file.

i tried to downgrade my phone from D85120B to D85110R using TWRP and zip files in first post. however the phone is now stuck in a boot loop , it cannot go into download or recovery mode.

all it does is show LG logo > blue light > t-mobile logo -> blank screen in continuous loop.

what are my options here. I have backups on my phone.

**solved***

Finally got into Hard reset mode and did a hard reset., lost all data but the phone is working again
[T-Mobile LG G3] ThePagel:
Yeah sadly 90% of the time you need to do a full wipe on downgrades. How is your cell connection after the downgrade? Did you have a old efs backup?

[T-Mobile LG G3] ThePagel:
No, personally I wouldn't even flash the bootloader unless you are noticing problems. I have the updated rpm in these zips but if you want the rest of the boot chain you can do it before or after.
[T-Mobile LG G3] ThePagel:
Added: D85120E-Untouched_Stock_Restore.zip to the TWRP section

Added: D85120E_00.7z to the kdz section

Note: If you want the latest boot chain you can grab it from autoprime BUT I would

recommend

not doing that unless you are noticing problems. In my

personal opinion

the rpm is the only truly important part of the boot chain to update and all of my twrp files update the rpm.

flash superuser and then twrp

If you have xposed you should do a system and data wipe before flashing just to ensure no problems. Make sure you backup your files and put the Zips on your external.

LTE won't stick

I updated using KDZ and the D85120E_00.7z file and now my LTE won't stick. I will set the phone to GSM/WCDMA/LTE auto and after a few hours or a connection loss or if airplane mode wifi etc is activated it reverts back to GSM/WCDMA auto which means I can't get LTE unless I go back into the settings and change it again. It will always boot up on GSM/WCDMA auto as well. Does anyone know how to fix this? :crying:

I tried rooting it but when I run the command to flash superuser the script runs and I reboot and nothing has changed

[T-Mobile LG G3] hodgestl:
So one last question before I pull the trigger and upgrade this. I am already on the old LP 20b with root and TWRP. So can I just flash the new 20e zip file and Super SU and still have the TWRP that I have now? I don't know if re-flashing TWRP, since I already have it, might screw something up. I certainly would not want to do anything that would prevent me being able to restore a Nandroid backup. Thanks again to any and all who help. You guys are amazing.
