[Q] How to Lollipop -> KitKat root, EFS etc? - G3 Q&A, Help & Troubleshooting

I am on stock Lollipop and plan to revert back to KitKat. I understand that it needs to be using Flash Tool. However, I have following questions:
1) How do I take backup of EFS? I am on stock non-rooted lollipop.
2) From where to download rooted KitKat KDZ?
Thanks

1) You can't do it without root. No, lolipop is not rootable.
2) You can't. KDZ can't be "prerooted".
You can download any 4.4.2 kdz, install it, root using purpledrake, install twrp, make a efs backup, install prerooted 5.0 rom...

yes, I understand that. But how to preserve EFS/modem while reverting back from lolipop to kitkat? I was reading that it's required, please correct me.

yes, but I need to go back to kk first. I was on v10J-SEA-XX before Iollipop was installed and so was looking for that kdz. Are you suggesting any kdz will do? Also, how do I safely go back to lollipop from KK without losing EFS/Modem.

1) No way. You -can't- backup efs without root. And you can't obtain it without downgrading to 4.4.2.
2) Just flash any 4.4.2 kdz. You won't lose efs, that partition is not being written to in update process.

I am having the same problem and strongly advice to hang on with lollipop till a valid tutorial is available for safe downgrade.
Till now I have tried flashing Kitkat over 10 times and every time I get an unknown baseband, null imei problem. I have also tried backing up EFS from lollipop and restoring on Kitkat but that doesnt work, maybe if you have EFS backup of your Kitkat version you can safely downgrade but otherwise it is not possible.
I believe the Samsung Lollipop update came with an EFS update which makes Kitkat unable to read Lollipop EFS, and without EFS you won't be able to use the phone properly.
Hope my experience helps.

Re-flash stock recovery. GET RID OF TWRP

Hello, everybuddy, i recently installed twrp via flashify on my g3. Now that i see android L is being released, i would like to get the OTA for that so i have to get back to stock recovery. Can i just flash it via flashify? and if i can what do i flash? and will it be the same as it was before so i can get OTA? im also rooted, will i get eh OTA if i have root? i know it will kill it but i dont care about that, i just want to make sure ill get the OTA
Your best bet will probably be to follow this guide here:
http://forum.xda-developers.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667
This will take you back to stock. Getting rid of TWRP is not enough to get OTA to successfully install. You also need to unroot and restore any apps that you may have frozen or removed such as CarrierIQ. Additionally remove xposed if running. Again, instead of going through that trouble, it would be easier to get restore to stock since it's a quick flash.
Note: I would not necessarily be in a hurry to take the OTA. It's possible that it may not be easy to obtain root. Thus I would suggest waiting till one of the devs has had the opportunity to review and confirm that root can still be obtained.

You still running pac rom? If so OTA will not work. However if you already flashed back to stock and are just rooted, then yes you can unroot and flash back the stock recovery. I believe the stock recovery can be found somewhere here. If I find a link I will post.

Hi, I am looking for flashing stock recovery on my LG G3 Sprint LS990. I believe the same method will work. I am currently running on stock ZVB ROM rooted and TWRP installed as recovery. In the download folder for LS990-ZVB http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVB, there is no recovery image file, but in ZVA folder there is. I am just wondering if I can flash ZVA folder's recovery image using Flashify to my ZVB ROM LS990 and if that will work.
My LS990 is rooted and currently have TWRP. i get secure boot error when the phone reboots after accepting Android updates installation that come automatically. I believe installing stock recovery will resolve this issue and allow to install Android updates I do not want to going back to stock completely, that will unroot my phone and again I have do all these staffs.
Anyone can help to advise, will be appreciated. Thanks.

LG G4 problem with stock reset

Hello,
Everyone I have a problem with my LG G4. I rooted it a few months ago and now I ran into a problem so I decided to do a factory reset in hopes to get a clean stock version. After the phone was cleaned off I noticed that Super SU was still installed which I thought was weird so I checked the rooted status and it was still rooted. I have no idea how it could still be rooted after a factory reset. I want to do all the updates for the phone and re-root it again but it is stuck being root at the moment.
So I found this guide --> [Guide] LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method.
I couldn't get this flash kit to work on my G4. I have tried it on a Windows 10 laptop and windows 7 laptop to see if there was a difference and still no luck.
Does anyone have any other methods of resetting an LG G4?
Thanks everyone
Just download the kdz you need and flash it using this tool. Works 100%. Cheers

Does it matter that it is a verizon with vs98611a?
If you still have the backed up system.img (before rooted), you can flash it back like you did to root. Please read in the low effort root thread how to backup system.img (before root) and to restore it. I also ran into this problem, supersu couldnt be full unroot and I had to restore the backed up system.img (since I didnt have the kdz).

Unrooting help URGENT

Hi I want to unroot my G3 so I can get marshmallow without the fuss and stuff. The thing is flashing a stock lollipop will delete my data, which to me is very important. So I really have no idea of how to backup fully(except rom) other than taking a nandroid. Are there any other ways of unrooting which will undo my mods and stuff, keeping in mind I'm on a stock rom which is rooted, or any simple way to do a backup and restore from a rooted rom to a stock rom.

If I'm not wrong, when you flash the .KDZ it will un-root automatically your device. But just download Titanium Backup and backup all your apps, then install the bumped version of the MM (if you don't have TWRP installed, it is very easy to do it in LL).
I don't remember if Titanium can install all your apps back with theirs respectives datas without root, but you can root the device again if you install the .zip via the custom recovery. You can do it as well if you flash the KDZ, but as I have installed the bumped Marshmallow, I'll let someone else explain it to you.
Of course, if you still want to unroot, as you are in lollipop you probably used Kingroot or some app like that. Just open the app and try to find an option to unroot, most of them have it right when you open it.
Sorry for any typo or broken english, I'm in kind of a hurry

You can always root it again and restore your data using Titanium =P. The recovery is only needed to flash custom roms ou .zip files, like Viper4Android (although you can download the non-official one from Play Store), mods and etc.
I know there are some apps that don't need neither root nor custom recoverys, but I haven't used any of them, so I will let someone with more experience in that area explain it to you.
Just one more thing: I saw that there are ways of downgrading back to lollipop if you flash the official KDZ, but they're a little bit tricky, so I still recommend you to flash the .zip through TWRP (upgrade it to the 2.8.7.1 version if you haven't done it already). If you need more help, or if I wasn't clear enough, just mention or quote me and I'll se if I can help

There are 2 ways to get stock marshmallow running on d855s now:
1. Flash via TWRP 2.8.7.0 by following instructions from here.
2. Downloading KDZ file from here and flashing using LG Flash Tool 2014 or LGUP tool.
I would recommend that you use method 1 since you are rooted. You can use TiBackup to backup your apps+data and after flashing you will still have root and you can restore apps+data using TiBackup.
Also, method 1 is better than method 2 because if you use method 2, you will lock your bootloader and lose root. You MAY not be able to downgrade to Lollipop, and I don't think there's a reliable way to root stock marshmallow just yet.

I think you're misunderstanding me, I'd like to go back to an unrooted version of lollipop and eventually get the official marshmallow update. I don't want to get involved in flashing and stuff, it's just time consuming. So to sum it up - go to unrooted lollipop with all my data(no root mods) and wait for official update.

He wants to unroot the phone and keep all his data, so the only way he could flash the LL kdz and keep his apps would be rooting again and installing the backup using Titanium.
@OP, what root metod did you use? Helium propably will work, but I haven't used it yet. Try opening your SuperSU app and selecting the option to unroot in the settings. Most of 'em have it.

If you flash the KDZ using the CSE_Flash option, yes, it will unroot the phone. If you just dirty flash it, I don't know, maybe.
If you unroot by using the option in SuperSU, you'll be able to update using OTA, you will only have some issues (aka bootloops) if you have a custom recovery installed. If you have, don't EVER try to install ANY OTA.

By repairing, you mean just unroot and install the stock recovery back? I don't think so, the .KDZ file is a full OS. If you flash it you will have your stock recovery and will unroot, but your phone will be factory reseted

I don't think there is any option besides restoring the stock recovery. I've seen a way of doing in somewhere in a Brazilian forum, but you would have to have a backup of it, which I don't think you do. Anyway, your best chance is to use titanium backup to backup your data (and move your photos and videos to the sd card), restore the system by flashing it using the flash tool, root it again, restore everything using titanium, and unroot. But I highly recommend you to keep your device the way it is, and update just when there is a deodexed Rom or a custom stock Rom available. After you get used to having root and a custom recovery, there is no turning back.

i think you can try rooting with kingroot, then flashing twrp, then flash cm13. Though I have not tried this method before. From what I read kingroot only gives temporary root which lasts a reboot so you gotta download everything, root, install autorec from play store, then reboot into twrp and flash.
Don't try Autorec method on Marsmallow rom. It will hard brick your phone (it's hard to repair it for inexperienced user).
What I recommended is tot method for retrieving stock lollipop. Then you can try root and Autorec.

G3 root problem [Help/urgent]

My phone is LG G3 D855 international model and I recently have upgraded it to android 6.0. However I am quite disappointed with the performance to its performance and would like to downgrade it to the older version like android 4.4 so as for easy root of the phone and flash fulmics rom. And a problem comes out- I cant downgrade it officially ! No matter I am flashing in tot files or kdz files, I can't downgrade. So I tried to root it directly and no matter what method suggested in the net , I failed to root my phone. Errors,errors, and errors...I am enough with errors and would like to ask for help in order to solve my problem. I genuinely want to flash the fulmic rom into my phone! My phone lags so much!!!!

My phone is LG G3 D855 international model and I recently have upgraded it to android 6.0. However I am quite disappointed with the performance to its performance and would like to downgrade it to the older version like android 4.4 so as for easy root of the phone and flash fulmics rom. And a problem comes out- I cant downgrade it officially ! No matter I am flashing in tot files or kdz files, I can't downgrade. So I tried to root it directly and no matter what method suggested in the net , I failed to root my phone. Errors,errors, and errors...I am enough with errors and would like to ask for help in order to solve my problem. I genuinely want to flash the fulmic rom into my phone! My phone lags so much!!!!

I successfully rooted now but I failed to flash in Fulmics 3.5 rom as the system said 'set_metadata_recursive:some changes failed'
What should I do?
I don't want to loss my phone !

Do you want to make a clean downgrade to Android Kitkat from Marshmallow? From what I see, you're root. If you do not have recovery installed, you can install the official app of TWRP which does install the recovery. After that, download Kitkat official rom in format zip (look in xda threads) and formats your rom from the recovery. For example, the name of the rom for my variant (Lg g3 D851) is D85120G-Rom_Untouched_Stock_Restore.zip
