Thanks. So, does it mean that it would be possible to root MM?
[G4 Q&A, Help & Troubleshooting] xDreDz:
so i tried to downgrade from MM to LP...

It was good till my battery went out.

I recharged my phone for 30 mins then went back for the flash.

It immediately finished. In just under 5 mins.

My phone kept booting. rebooting. now its dead and it wont even open...

Now what? damn it that MM upgrade destroyed my phone!!!!!

I tried to have it fixed because of the " hardware fault " but they didnt want to fix it.

LG shoult atleast replace my phone or give a refund
[G4 Q&A, Help & Troubleshooting] shadavis08:
You have to have a full battery whenever you flash your phone. Or this kind of stuff happens. Try flashing it again. Or try booting into recovery by powering on the phone holding down power and volume down button at the same time and then factory reset.

[G4 Q&A, Help & Troubleshooting] divineBliss:
Do you have the correct KDZ for your phone model? Could the KDZ file be corrupt? Maybe download it again or confirm the checksum is good :confused: or does LGUP prevent all those type of errors?
[G4 Q&A, Help & Troubleshooting] xDreDz:
Slapped my phone then i went for another flash. it was 100% on LGUP and no errors.. But still. my phone wont boot.

I redownloaded another kdz file. the proper one and it is what i used..

and still.. nothing. im still under warranty.. but. i dont know if theyll still accept this
[G4 Q&A, Help & Troubleshooting] shadavis08:
They should accept it it won't even boot up.

---------- Post added at 08:35 PM ---------- Previous post was at 08:32 PM ----------

your battery dieing in the process of flashing is what messed everything up. So maybe someone else I the forums has had the same issue maybe start a new thread asking if someone knows a fix for this situation.
[G4 Q&A, Help & Troubleshooting] xDreDz:
They got it. But this woman keeps on arguing with me that its because of the battery. and she used other batteries from other phones without me knowing it. luckily my gf saw everything..

ro.lge.swversion=some info

ro.lge.swversion_short=some info

change to

Code:

ro.lge.swversion=H81510c

ro.lge.swversion_short=V10c

but nothing when I want to save, a message says: error in save process, the file will not be saved!

LGUP or gives me "unknown device" or find "H525n" but then when I click "Select" appears "LGUP can't load the model C:\.....\LGUP\8916dll....

Hi guys,

I've recently had my H815T repaired and it's come back to me with v10B-OPT1-YT. The hardware info still shows H815T.

I had updated via LG Bridge to v20C, after completion the software shows v20C-OPT1-YT, I was hoping it would show v20C-HKG-TT. The hardware info still shows H815T.

Getting further annoyed at this, I decided to use LG UP and 'refurbish' my phone back to V10B-HKG-TT .KDZ for the H815T using the methods provided however in doing so, it still shows v10B-OPT1-YT

BUT

now the hardware info shows LG-H815 WITHOUT the T! Does this mean I have disabled Band 40 due to the model number change? Have I just monumentally f**ked it up somehow?

To add more to the problem, LG Bridge still indicates my phone is ready for an update for H815T v20C (04.02.2016) but I had already updated to that version...

Any developers able to assist? My OCD is going ballistic lol, I wouldn't have paid extra for the T model if I didn't intend on using B40!!

Hello, VS98624C.kdz (Refurbished option) not working, "USB port is not opened" help please.
[G4 Q&A, Help & Troubleshooting] SirDarknight:
My LG G4 H818P came with Marshmallow 6.0 installed. It had bugs, unrootable and bad battery life. So, after a week or so, I used LGUP to flash a stock Lollipop kdz and then rooted it. Both of the procedures went just fine.

But the battery life has worsened drastically, let alone improve. For instance, I checked the battery at 92% before going to sleep and woke up in the morning with 71% but the whole time the screen was turned off and nothing was going on background. The battery doesn't even last 1.5 hours when I'm watching a movie or browsing the internet.

Just clarifying a few things seeing as I had an issue with my S5 and went this route and ended up hard bricking it... (It was randomly restarting after a factory update)...

1) This will work for my verizon G4 VS986 on the VS98625A software version?

2) I install the DLL file before the Install file correct?

3) Is editing that code you posted normal because I dont want to screw that up.. Or was that an isolated case?

4) Lastly, you reccommend 13b correct?

Also, what is TWRP.

Thanks

Marshmallow is destroying my battery life and I recently had my first G4 just stop turning on and they sent me a new one that has MM on it -_-"

Hi all,

I created the following thread

http://xdaforums.com/g4/help/marshmallow-update-lg-g4-lmy47d-t3390418#post67133480

I am looking to install MM on my LG G4 which is running stock LP and when I load up the LGUP application my device is recognised and shows the model as being:

H815X10c

The details of the device are:

Kernel: 3.10.49

Build Number: LMY47D

Software Version: VX10c-EUR-XX

I understand the process of using LGUP however I am not sure which version of MM I should download, I don't get which H81520 ROM I should download and install, do I need C, B, D etc? As my current device is VX10c does that mean I should install H81520C? What is the difference between each of the different versions of the v20 ROM.

I just wanted to make sure before I go ahead and try this.
