[STOCK][M] NEW! H815 20G Images + KDZ + Flashable Zips (system+boot+modem+bootloader)

[autoprime]

These are for the H815 variant only. Files are from software version 20G (Android 6.0 Marshmallow)... more specifically from the 20G Poland carrier-free version. Included below: TWRP-flashable stock rom, boot, modem and bootloader zips. KDZ and individual images are also included.​

20G NOTES...
Improved stability for apps.
Phone usability and functionality has been further improved.
Android Security Patch = 2016-07-01
*There is NO anti-rollback qfuse used in this update*

Requirements:
You must have TWRP 2.8.7+ installed to use these zip files. Thanks to Dees_Troy as always for that. And, of course, you must have your bootloader unlocked for TWRP to work. Currently only H815 EU and (some) SEA variants have official unlock through LG's unlock page HERE. Please do not ask if "model x" is supported... did you unlock via LG's official unlock tool? Yes? then you can use the zip. No?.. then you should skip the zips and just flash the KDZ instead.

If you have a locked bootloader and want to upgrade... just use LGUP and flash the KDZ. Don't risk it with FlashFire.

Install Directions:
These directions should be used by everyone who wants a rooted 20G system.
Don't want root? Then it's probably easiest to just flash the stock KDZ using LGUP HERE... or just skip the SuperSu steps.

1. Download LG-H81520G-Flashable.COMPLETE.zip listed under the download section and place it on internal or external sdcard.
2. Also download the latest SuperSu zip (2.67+) from HERE [Thanks to Chainfire for his auto-patching boot.img version!]
3. (re)Boot into TWRP if not there already.
4.* Backup current partitions: boot, system, data, efs (backing up anything is optional but suggested)
5.* Up to you if you want to wipe data (TWRP > Wipe > Swipe slider) but not needed if coming from a stock rom.
6. Install LG-H81520G-Flashable.COMPLETE.zip (Install > select zip > swipe to confirm/flash)
7. Install SuperSu zip (Install > select zip > swipe to confirm/flash)
8. After zips finish flashing you can reboot! (if TWRP asks if you want to install SU, HIT NO!!!)

Please do not mirror my files!

Downgrade:
To downgrade you can use TWRP to restore your backups... and then just flash the matching bootloader zip and modem zip from my previous threads... or just check the CODEFIRE DIRECTORY link for previous stock files.

OR

Use LGUP HERE to flash a previous KDZ version. KDZ will remove TWRP but easy enough to reinstall that.

Unofficial Bootloader Unlock:
Don't have official bootloader unlock? This guy claims to have a working method HERE...

Awesome! If I'm already running Imperium 5.0 and just want the updated bootloader and modem (currently using the 20d variants), I'm guessing I can just backup and flash the modem and bootloader zips in TWRP? No need to completely return to stock/install the full zip?

Potentially silly question, but I'd rather ask than end up doing irreparable damage.

correct.. there is no need to flash full unless u want stock(or stock rooted) lg. an updated modem/bootloader may or may not agree with the system/rom you're using though... sometimes things change where the "rom-base" must be updated to work with the new modem or bootloader. but worst case you just flash the old modem/bootloader back. If I had to guess though I think it should work for ya.

Great, thank you.

 

[heino69]

is it also valid to use newer versions of SU and TWRP as listed in the OT?
In detail I have
twrp-3.0.2-0-h815.img
and
UPDATE-SuperSU-v2.76-20160630161323.zip
I just want to verify, because in a german forum is an ongoing discussion if the 20g version can be rooted or not (or only till 20d)...

Thanks!

no mobile data on LTE

 

[kaitwo]

no mobile data on LTE

H815 EU version.
Mobile data properly working.

 

[colemarc]

Well, about 5 hours to download H81520G-Flashable.COMPLETE.zip
I bet the download is going to stall...
It seems downloads.codefi.re is really slow, and no download manager supported.

 

[fbr79]

After days of use, I can confirm that the version 20g greatly improves the stability and lifetime of the battery. also reduces the heat.
Using 20g kdz ITA on H815 no brand EU serial 601.

 

[Hudt]

Is this kdz working fine in brand phone? If do not show a message about software incompatibilities

 

[android404]

Does xposed work on this version? There was a time when xposed didn't work on stock marshmallow rom without them being deodexed. Is that time over?

Edit: yes, those times are over.

 

[alejobog]

Please...mirror KDZ, thanks

What is the baseband version of the modem?

 

[android404]

What is the baseband version of the modem?

Here

 

[Klussenpunt]

Hm. Baseband version is the same as in latest CM13...

Cm13 does not bring its own baseband, i dont remember what bootloader/modem i flashed last to my device as it was a while back, i think it was v20d, but i have same baseband as well, so i guess they dont do a lot of changes.

There's a lot of trouble with mobile data on CM13 nightly. Toggle on/off air plane mode is necessary to get your mobile data. After I made an issue in JIRA one of the ideas was that it was an outdated modem. In the mean time I've installed the Omni Rom (same baseband as in this thread) and there are no problems with mobile data. So it's a CM13 problem. The Jira issue is assigned to a developer, but it's silent for quite a while.

I run the same modem firmware and have to toggle airplane mode verry verry rarely, maybe once a month or so when turning off wifi. This may be some heißenbug hidden in the ril but in my case i dont care a lot obviously.

Which dev is assigmed to the issue you filed? Is it daniel hillebrand (codeworkx)?

[Klussenpunt]

Yes it's Daniel.

 

[FadeFx]

Yes it's Daniel.

He is quite bussy with real life atm afaik, so probably didnt even look into it. Maybe you should also send a link to the bug to erwan @genesixxbf3
