Forgive me for my newbie questions and the possibility that there is a condensed thread somewhere that gives me a step by step guide. I searched, but failed to find one... :)

I just bought this unit:

Pumpkin Quad Core 7-inch 1024*600 Digital Touchscreen Double Din UNIVERSAL Android 4.4 Head Unit Support GPS Navigation/Radio FM/AM/Bluetooth/Subwoofer/EQ/1080P Display/AUX/3G/WIFI/Reverse Camera/OBD2/Steering Wheel Control (Car Stereo with GPS)

After using it for a few weeks there are some REALLY annoying things bout it that need addressing.

BT music player is terrible. No track info and only basic navigation tools from on screen.

Radio screen is horrible too. The station name is tiny and the ability to store your favourite stations on the buttons you choose is missing.

Music player is nasty to look at, especially if you have 80Gb of tunes to plough through.

So, it looks like I need to change the software. But HOW? I need a simple step by guide to help me out. I don't want to brick the thing! Specs are:

UNIVERSAL head unit.

OS: Android 4.4 Kit Kat,

CPU: RK3188 Cortex A9 Quad Core,

RAM: DDR3 1GB Nand Memory: 16GB,

Screen Resolution: 1024*600,

Can someone help me please? :good:
[Android Head-Units] RS-TLS:
Bricked it. Damn it all.
[Android Head-Units] ROCNDAV:
I use Rocket Player on my phone (Galaxy S6) and on my Car Stereo (AN-21U). It's much better than the default player.

The FM tuner I have sucks. I can program the radio stations by holding down the preset that you want for a few seconds.

The catch is, timing the display correctly. If the station ID is being scrolled, it will store that, if it is the song title, it will store that. stupid!

I hate the scrolling radio station / Song ID.

Some stations (93.1 Jack FM, here in Los Angeles) , actually display both, in one line in white text below the scrolling text.

I don't know why they don't use that souce, or better yet, just display the station and song correctly.

Open Play Store ... download new music player? I use BlackPlayer in the car right now. The radio I stole from another ROM but it still sucks, just not as bad (rooted mine). Mine is the Lollipop version though, so dont know if my ROM would brick yours. In fact, the radio might be the same as the old 4.4 based unit!
[Android Head-Units] uudruid74:
Not all bricks are equal. Were you able to get to recovery before you bricked it? Can you now?

In the future, you need to remove the part that updates the recovery image before flashing so that it never overwrites your only means of fixing the problem :) Its also safer to take a factory image for your device and modify it than to trust some image made for some random unit.
[Android Head-Units] RS-TLS:
I was able to get to recovery before flashing bricked it. No, no way I tried could get it past the bootloader, and I tried every way known to this community.

"In the future, you need to remove the part that updates the recovery image before flashing so that it never overwrites your only means of fixing the problem". Hmm, was not aware of this, or how to actually make it happen...

" Its also safer to take a factory image for your device and modify it than to trust some image made for some random unit."

Sadly, my lack of skills in this area prevented that, which was why I used an image I thought was trusted and safe. Needless to say, I have not attempted to flash the replacement unit even though it has features that boil my piss each time I use it. ;)
[Android Head-Units] CadillacMike:
I just use Google Play Music now, but when I did try other players, BlackPlayer was by far my favorite
[Android Head-Units] uudruid74:
The updates are in Rockchip update format. XDA has a tool floating around for Linux (imgrepackerrk) that can open the file. A tool for Windows is on the Rockchip website. Inside you'll see an update script. Note the lines I commented out:

# <C9><FD><BC><B6>recovery

#write_image PACKAGE:recovery RECOVERY:

#check_image PACKAGE:recovery RECOVERY:

# <C9><FD><BC><B6>system

write_image PACKAGE:system SYSTEM:

check_image PACKAGE:system SYSTEM:

# <C9><FD><BC><B6>backup

write_image PACKAGE:backup BACKUP:

check_image PACKAGE:backup BACKUP:

You'll also see a system.img, which is a raw ext4 file system image that is easily mountable on any Linux system. There are some Windows tools to deal with it too. You open the system.img, tinker, then repack it. You basically can't hurt the system if you only play with the system.img since you can always reflash the factory one. Everything else stays the same and recovery is never touched.

Hopefully this info will be useful to the next person [emoji2]

The power button works occasionally.

When I turn off the LG G3 D852 phone it won't turn on unless I pull and replace the battery and press the power button again.

I have tried changing custom ROMS (Carbon 4.4 and and Res Remix 6.0.1), changing batteries (original battery and brand new Anker).

I thought it was a hardware problem but why would the power button work after pulling the battery?

I know I can leave it on all the time, but it bothers me.

Would appreciate any help and thanks in advance.

issues after mm upgrade

Here's what I experienced after update...

Once you upgrade you can't flash back to stock. LG flash tool fails because it couldn't detect the model. After setting up McAfee it disables root and usb debugging. You have to go into McAfee and turn those options off. So it seems like once you go to mm you can't get back to lollipop. I'm also having proximity sensor issues also with the screen going black during a call. I guess once we can get root I'll be able to install another rom.
[AT&T LG G3] vishnugs:
Hi, I got the notification and I was not in WiFi network so decided to cancel it and check it again once I got to wifi zone. But when I checked next time, I just get a message, your phone is uptodate. I tried rolling date forward to circumvent the 24 hour check, but no luck. Any ideas to get the update notification back ?
[AT&T LG G3] cobyn:

Update

I had the same thing happen to me so what I did to make the phone think I haven't checked for an update and avoid the 24 hour wait I did a hard reset. I want to point out that I didn't care much about all my apps being deleted and you might want to back them up. Note: I was on stock lollipop

Please let us know if you get it accomplished.
[AT&T LG G3] hyelton:
Not sure if there is an "anti roll back" But You cannot use flashtools once updating to Lollipop you must use LGUP.
[AT&T LG G3] louvass:
Where do I get a KDS for the 850 along with the LGUP, seems everything points to the 855? thanks. I can't seem to root after the upgrade to 6.
[AT&T LG G3] hyelton:
Its KDZ. the D850 is TOT method only.

But remember its your own risk, not sure if downgrading will brick or not yet from MM on the AT&T Model.

FWIW, if you're experiencing DND issues after the 6.0 update check settings > dnd > advanced > schedule. kept noticing on my moto360 it was switching to dnd for no reason. turns out some scheduling magically appeared. been running 6.0 without a hitch since last night. had to manually disable at&t video calling and a few other things but im happy with it thus far.

I tried doing a factory reset after spending a lot of time to back up data. But after fresh restore, I'm getting the message that your phone is uptodate. I m cursing myself why I dismissed the prompt yesterday. Any other solutions to force update ?
[AT&T LG G3] louvass:
Thanks yes I know how to use the flash tool...my problem is it fails every timeI try going back to stock lollipop.
[AT&T LG G3] cjoeone:
You have to do a hard reset through stock recovery. Don't do it if you are using a custom rom. If you are not experienced I recommend you wait to see if you get another update notification
[AT&T LG G3] hyelton:
That is because flashtool you cannot use if your on MM you use LGUP with the TOT file.
[AT&T LG G3] louvass:
Can you send me a link for it thanks man..i got it thanks
[AT&T LG G3] hyelton:
It's in the 2nd post of my guide in the link I posted earlier ^^ :) but just remember at your own risk as I haven't seen anyone try yet. Example like the G4 after a certain point people bricked there AT&T model from downgrading. But if you do risk it and everything went smoothly let us all know!
[AT&T LG G3] vishnugs:
No luck, tried hard reset through recovery twice and before that general reset several times. I'm not getting the notification for the second time :(

Any other ways to force update ?
[AT&T LG G3] louvass:
Thanks

Thanks it worked well, I just wasn't sure with the file names 855... didnt want to brick. I took a shot, got back to stock LL thanks. So with being back to lollipop can I use the original tot and dll from the 850 using the LGUP instead of the flash tool. Thanks again

I quit rooting some time ago. Initially rooted and used Roms because they performed so much better than stock, but these days disabling apps and using a different launcher alleviates that issue for me. What's the current benefit of rooting/roming?

Still waiting on mine, but I may not get it OTA because the SIM, though installed, isn't active (the one on my 6SPlus is).
[AT&T LG G3] aybarrap1:
For some of us rooting still has benefits. I for one stick with stock ROM, but disable the bloat. There are some apps and services that come preloaded by both the manufacturer and the carrier that can't be disabled unless you are rooted. Not too mention the expandable abilities of Xposed and Tasker so I have more control over how my phone operates.
[AT&T LG G3] thatkindaguy:
Hey guys, for those of you who are having trouble updating because of the 24 hour limit or whatever, you can try factory resetting, then try the software update. Worked for me :)

Phone is stuck

I got the update and tried to do it but (i forget what it told me exactly) but I HAD rooted my phone in the past but I thought I'd unrooted it fully. Went through the processes and deleted all files and downloads for any root apps or root things on my phone and it wouldnt let me update. So i found out to flash my phone back to stock 4.2.2 and (I forgot itd wipe ALL my data. ...) anyways, NOW either through PC Suite or wifi or data with or without the SIM card I cannot update my phone and its stuck. I was on the latest Lollipop version but i cant even get back to that now. I think i might have an international version flashed to my phone but im in USA with the AT&T d850 model. Can anyone help? Been searching for the past few days now..
[AT&T LG G3] hyelton:
Its always stated that it will wipe all data.. What do you mean you think an international version flashed to your phone? You cannnot do that, if you flashed a D850 TOT then you have D850 AT&T firmware.

So your using the phone on AT&T? If your not using it on AT&T you cannnot get OTA updates. If you are on AT&T make sure you've performed a few factory resets.
[AT&T LG G3] fortunateson97:
BY International i mean i think that. Not for sure. May just have read something wrong. My software version is D85010d(idk if international or not) and i AM on AT&T. And as for Factory Resets, Back up ALL Data(that ive been able to recover so far anyways) and THEN fact reset? Should work? (PS I knew it wiped data but had forgotten since i hadnt done anything that technical in a long time.) Thank you for the reply btw.
[AT&T LG G3] hyelton:
The D850 is AT&T USA only. There's no non Att D850. Try doing a few factory resets ota with LG phones and AT&T models are terrible.

Problems with update

I don't know if anyone else is having this problem.... I unrooted my phone and tried to download the 6.0 update. The update starts, but runs REALLY slow, and then I get a message "unable to complete download". The most I've ever gotten is about 15% of the download. I've tried to d/l the update using LG PC Suite, but it shows that I am up to date.

Any suggestions? I know my Wi-Fi connection is reasonably fast... could the problem be that I did root the phone and that's causing problems?

Thanks!

Unrooting is not enough. You have to flash back to stock.

Getting MM 6.0 for non-US users

Hello people! I've been following MM threads for the D850 for a while and lately been considering moving from my currently debloated stock LP to Fulmics or Blacksoulxxx's custom ROMS, but I definitely prefer stock ones. The thing is I live outside the US, so no OTA for me. I have 2 questions!

1) Is there a way to get the KDZ/TOT/whathever of this new MM release? Do you know if its available for download somewhere?

2) Is there a known way to force the FOTA upgrade with a mod or so?

Thank you!!

if you let google backup your apps/contacts/photos when you reboot from a factory reset and login it should start repopulating all your stuff.

[AT&T LG G3] mrhaley30705:
I just had an epiphany concerning root. All it may take (may, not will, but may) is using twrp to flash SuperSU. Maybe. It's really a big guess on my part, using an 855 mm Rom as my basis. Blacksouls modded 855 stock Rom originally had to be rooted after you flashed it. All you had to do was flash SuperSU 2.52 and you had root.
[AT&T LG G3] ASwagBoy:
Yep, but you need the TWRP recovery and a flashable zip of the MM update for the D850, so... if someone is able to go back to lollipop and catch the OTA and upload it then someone can make a flashable zip then in the recovery you would just need to flash the zip and SuperSU and you will have MM with root
[AT&T LG G3] mrhaley30705:
Yeah, I didn't say it was a perfect plan ;)

May be wrong here, but I believe you have to have a recovery installed that allows a nandroid image to be captured which requires root. As of now there is no known root method for the D850 with MM.

I've provided the ingredients to the proper kitchens. Xpirt has a test ZIP to flash on top of a current Fulmics installation and Blacksoulxxx has updated his TekCafe ROM to include the updates.

If you just want the modem, grab it from xpirit's update ZIP, it's only 43 MB. No guarantees it will work by itself with your current ROM. Here's an untested flashable ZIP: D85030k flashable modem

As of yet, there's no way to install a custom recovery on stock 30k. I've also provided the necessary files for bender_007 to create an updated AutoRec version, so keep an eye out for that. Please don't ask him for an ETA.
