go back to 5.1 - G4 Q&A, Help & Troubleshooting

Hi guys,
I need help for go back to 5.1 stock rom.
Im installed MM 6.0 on my LG G4 with flashfire app. (Phone is locked bootloader and no root)
There is any way to go back 5.1 without unlocking bootloader?
Thanks for help.

with kdz and flasthool no . but maybe with flashfire and 5.1 room

I can't use flashfire app because i can't root 6.0 rom with lbl.

for now nothing to do
flashtool not supporting flashing MM or getting back to 5.1
lets wait for devs to find us a way

alright,thanks for answer

root (stump) , re-root (IOROOT), BUMP, TRWP,
Rooted with STUMP initially just fine. Then had to factory reset due to a malfunctioning app.
Stump does not (yet) support re-root after reset unless you flash back to stock. http://forum.xda-developers.com/lg-g3/orig-development/root-stump-root-lg-g3-sprint-verizon-t2850906
Thanks for all the helpful posts in several threads. I Rooted using IOROOT, using ADB no problem. http://forum.xda-developers.com/showthread.php?t=2776198
Now running BUMP TRWP recovery too. http://forum.xda-developers.com/ver...pment/bump-unlock-lg-g3-twrp-verizon-t2900590
BUT, since i'm somewhat of a n00b, i used Flashify from the Google Play store to flash the image. Worked flawlessly. http://www.droidforums.net/threads/...ock-and-install-recovery-on-any-lg-g3.275056/
(in flashify, pick 'choose file' and navigate to the .IMG file)
Thanks!!

My phone does NOT work so I'm not sure why the change log states 12B.
What was upgraded, fixed, etc from 10B to 12B? Not really a fan of downgrading.

Help, I rooted my phone and I get a warning everytime i open it

Hello
So after foolishly updating to Marshmellow and discovering that all my apps no longer update in the background, i flashed my device to the LG G4 V10D-226-01 software version, the 10D Europe Open from the LG g4 "Go back to stock rom" thread.
Problem is, everytime i open my phone i get "Warning: Current version is not available for user. Cant find matched cust for Nt-code mcc/mnc[22601],subset[ff]. I have looked both on google and here and everything i found was for the G3 model and it involved using a "custom restore" image. but no explanation on how to use it, its not a KDZ so i cant flash it.
I'm pretty new to all this and everything i wanted was to go back to my Lollipop variant after seeing how Marshmellow behaved on my phone. (not auto updating my background apps).
I appreciate any help you guys provide.
Thanks
u cant downgrade once u go to Marshmallow. Its a security thing tht was updated in the latest firmware b4 Marshmallow came out. Ur gona hav to start all over again wth the latest KDZ b4 Marshmallow
I reformated into a Lollipop KDZ by flashing my ROM from the "Go back to stock" thread. Problem has appeared after i did that. I am currently on Lolipop v10D
nobody has any idea on how i can solve this issue?

download the kdz file for your device from here and flash it using LG UP here. all will be fine. i downgraded from MM to LP after MM had big battery drain. many people have downgraded using this method.

I'm also interested in this answer. The only reason I haven't updated to (any ART) rom is because I'm unsure if I can just restore a Dalvik backup without issues. The only way I would attempt is with TWRP.
i tried doing by Flash tool and it gives error like 0000008
bring up the post!
Curious as well. I'd like to get root.
Windows user not sure how to do it on Mac/Linux
by MM to KK I assume you want to take the LG G3 D851 from android 6.x down to 4.x
here goes...
----
http://lgg3root.com/lg-g3-stock-factory-firmware/
http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
use the LG Flash tool plus the two files, follow instructions on that second link step by step.
LGD851_20140611_LGFLASHv160.dll
LGD851AT-01-V10c-310-260-JUN-20-2014+0.tot
That takes you back to the 4.x kitkat stock ROM, not rooted or anything.
----------------
To go north from there back towards Lollipop or MM you can at this point use
http://www.download3k.com/Install-LG-Mobile-Support-Tool.html
B2CAppSetup.exe
Install it, will put an icon on your desktop, plug in your phone, open the app.
It's pretty much automatic, it updates the ROM from KK to Lolli, then if you hit "OK" it will update from Lolli to MM
- I just got both of these steps to work in the last 24 hours.
I'm still trying to find a valid "Root" method that doesn't ask me to install a funky ROM.
I went from a KK stock-rooted(TWRP 3.0) rom to the MM 6.0 Rom, realized I didn't really want to set everything up again, restored my KK backup. Only problem was I had to reflash the modem. That was a couple of days ago and the modem was the only issue.
I'm unsure about flashing a new/clean KK rom over a MM rom though.

I think I missed a step, in KitKat this phone needs a special command thrown at it so the memory cards will be read/write.
On the play store SDFix: KitKat Writeable MicroSD
I think that might be what I was missing last weekend. My phone is currently on MM but I can't root it with any method other than Kingroot and Kingroot is Bad News.
Yes. It's possible!.

Go back to LP from MM or root MM?? Possible?

So I got my phone back from LG, the repaired it, it had the bootloop.. they updated it to MM So... we can't root MM can we? And I guess I'd have to use the LGUP app to go back to LP? But I have the ATT version so I don't have any KDZ, I just have TOT, will that work? I really just want to enable hotspot mostly more than anything else. Sorry, I'm sure all this must be answered somewhere but I gotta jet to go get the kiddos ....
NVM, just flashed it to latest 5.1 and rooted that.

Get from Rooted Lollipop 13b to Stock Marshmallow

I'm tired of the problems and struggle I've had attempting to use my rooted G4. I'm currently on 13b rooted and it's been giving me problems. It randomly reboots and doesn't start up at times. And it's so sluggish. I've gotten a replacement because I flashed the wrong kdz. I just want my phone to work without all these problems. I just want to get to the stock Verizon MM for my G4. Is this possible?
You should be able to flash the MM kdz - they can be found here in the general section. Be sure to verify it is the correct kdz.
Keep in mind once you go to MM you won't be able to achieve root without downgrading back to LP. I think there is a downgrade thread here in general as well if you need it.

Thank you I just downloaded the KDZ and flashed via LG UP. It installed without any problems. I'm aware that you can't root on MM, I'm ok with that. I need a break from rooting after all of this. Thank you I appreciate it!
Glad to see someone here not happy with rooting the G4. I don't find it worth the risk or the benefits worth it without the ability to flash custom roms. I've never rooted a phone without there being a way to install a custom recovery.
For anyone interested, The Android Central podcast discussed the topic of rooting and flashing roms a bit on their most recent episode. Most of them agreed that there isn't as much of a need anymore to root and flash roms and that it's kind of died down a bit. Features that people used to have to root their phones for are now available on most stock roms.

how to install LGUP tool
https://www.youtube.com/watch?v=igB5rnLRXSc&spfreload=10
i know at the end of the video it says close the app, but dont, just start it and you be upgraded to MM in no time just make sure upgrade is checked
if you want to start fresh, then you can just do what my video says to get refurbished checked
if you upgrade with a rooted rom you have to factory reset your phone inorder for MM to boot
