Well whenever you want to downgrade you have the guide that i made for it. :)
[G3 Q&A, Help & Troubleshooting] qazihamayun:
Yes, I tried kingroot and kingoroot, so there is no luck to root v30b(failed again and again tried 100s of time), I tried on last week. Yes I was downloaded D858HK - v30b from lg-firmware site. and then install it, after installation tried to root but no luck. can you tell me that how to root v30b? what you have tried ?
[G3 Q&A, Help & Troubleshooting] Sotiris02:
Look up i made a guide to downgrade at v30a it will mostly be rootable now.

I have D855,but i just really like to help others with their problems and help them find a solution. :)

As i staded if you look a bit up you will see a guide that i made for downgrading.It's easy but you should be careful.

:)
[G3 Q&A, Help & Troubleshooting] qazihamayun:
Dear Thanks for Guideline, If you start reading this thread from starting point, I already shared the method to root V30a... I already know that how to downgrade and root v30a, Yes, V30a is root-able and I already downgraded and using v30a... Lets find the way for v30b... :p
[G3 Q&A, Help & Troubleshooting] Sotiris02:
For D855 v30b is rootable :p
[G3 Q&A, Help & Troubleshooting] qazihamayun:
Dear, Have you seen the Title ?? D858HK is already mentioned there, So Telling for D855 doesnot make any sense :cowboy:
[G3 Q&A, Help & Troubleshooting] Sotiris02:
I just said for D855 v30b is rootable.

And i meant that in no time it will be rootable and for D858HK. :)
[G3 Q&A, Help & Troubleshooting] ivomin:
I'm sure qazihamayun didn't meant any hard feelings... it's just it has been several weeks since 30b came out... i think it is almost two months and still not root available.....

By the way I think D855 30b is the same as D858HK 30a and different from D858HK 30b

yes ive tried kingroot.It does work temporarily and hence,for a permanent root, i ran the autorec app for lollipop (took the risk) and guess what,my phone got HARD BRICKED!!!..It died..luckily was under a warranty and got it replaced..Hope they release autorec for marshmallow soon:cowboy:

[/COLOR]Guys, it's a pain to be able to get root for D858hk running android 6.0 and even if rooting is successful, getting a custom recovery is just WAYYYYYYY tooo risky and painful.. easiest is to downgrade to kitkat or lollipop and then root it and flash twrp...you can then flash a pre-rooted v30a (marshmallow) via the recovery..Anyways,that's up to you..For now, just follow this guide for the downgrade process using LGUP tool..I did mine today and loving the rooted kitkat ;) ...

[G3 Q&A, Help & Troubleshooting] Soundboy:
Thanks for that... But I don't think it would work because the phone won't boot, screen blank, blue/red led continuously flashing, and neither of my 2 PC doesn't recognise phone when plugged into USB ports - so to do a recovery. I took the phone to a repairer, and I was told; phone can't be recovered/repair because an IC is blown, and it was caused by me mistakenly using lollipop app (D858HK)LG G3 AutoRec-Lollipop Lollipop APK) to root on marshmallow 6.0 OP (already on phone). Therefore, I need to buy a new motherboard, which is as expensive as the whole phone. So, I just bought a cheap OUKITEL K6000 Pro instead (no comparison to LG d858hk, though). I'm never gonna attempt to mess with any phone again - too risky... £350 paid for my LG d858hk just went in a flash after owning it for just a year!
[G3 Q&A, Help & Troubleshooting] ramprashant66:
bro,you don't need to buy a motherboard..Your device is just hard bricked..i fell in the same situation with my lg g3 d858hk..flashed autorec lollipop on marshmallow.Just open the phone up and short circuit the pins to get it into fastboot mode and then flash the separate files from your .kdz firmeware..it'll be then be able to bootup but it'll still be messed up so you have to enter again into the fastboot mode and then flash your whole stock .kdz firmware..

All set and done! Phone recovered!..there are alot of youtube videos available..do follow them..CHEERS!

I did short circuit the pins...

Did you have a black/blank screen on your phone when you had your problem? If it wasn't for blank screen I'm sure I would have sorted it, because one needs to see what going on on screen to be able to do anything. Plus, PC has to recognise phone too. And again, the phone repairer couldn't repair phone after leaving it with him for 3 days.

'How to Root LG G3 D858HK Marshmallow (6.0 V30a)

The answer was to wrong thread.
[G3 Q&A, Help & Troubleshooting] rk2612:
What version are you really on and where do you want to end up? And are you on fully stock or currently rooted with custom recovery installed?
[G3 Q&A, Help & Troubleshooting] Soundboy:
Done all that you suggested...; but PC doesn't recognise phone when plugged into USB port/s; and, the phone screen is black/blank. PC recognised phone before it was hard bricked. Therefore, because phone screen is black/blank, I couldn't see anything on screen to carry out procedures.

I'd already rooted the phone with Marshmallow and was trying to flash TWRP with https://play.google.com/store/apps/details?id=b007.autorecd858hk when it hard bricked my phone.
[G3 Q&A, Help & Troubleshooting] ivomin:
How are you trying to go into download mode (exact procedure). Apart from that, basicly all you need is to flash one of the original roms ( check https://lg-firmwares.com/) using LG Flash Tool....

Now the last resort is actually going into QCOM mode where you have direct access to the memory using the qcom tools. You can search how to go into that mode and what to do from there. I have never needed to go into it regardless how much I was playing with the memory and all.

For download mode - hold vol up button and at the same time insert the usb cable. Wait for windows to recognize it and install the drivers(10 minutes). Then remove battery from phone and do the same procedure.

I have tested it on windows 10 and 8 and had a lot of issues so i suggest using windows 7 for that procedure.

Don't panic... you phone is not that different from your PC and once you understand that you'll see it is not that hard. It's just a matter of writing the right thing on right places in the memory (as long as you don't have hardware problem).

For rooting 30a the best method is actually using kingroot. After that (as it installs some bloat) install twrp and then some custom rom (fulmics if you want lg interface based on 6.0.1, or some of the android 7 roms (mokee, crdroid, lineageos-unofficial.... pure aosp based))....
[G3 Q&A, Help & Troubleshooting] Soundboy:
I had rooted phone with 30a to begin with and it was ok until I tried flashing TWRP by using the wrong "Lollipop app" https://play.google.com/store/apps/details?id=b007.autorecd858hk (that was meant for Lollipop d858hk phone, and not Marshmellow 6 d858hk phone). After that, I reboot phone; but after waiting for ages for something to appear on screen - nothing. Then I realised something was wrong. So then after a few days, I googled...and read up about download mode, etc and shorting pins. So, I tried download still black/blank screen and PC doesn't recognise phone in USB. Then I also used QCOM mode - no success either. Then I short pins - no success there either.

I think there may be conflict issue between Marshmallow 6 & lollipop (https://play.google.com/store/apps/details?id=b007.autorecd858hk0) so causing boot looping, hence the blue/red LED continuously flashing and black/blank screen. The fact that I can't see anything on screen and PC doesn't recognise phone, trying to repair the phone would be impossible. If only I can see what comes up on screen (if there is anything at all), then I would have repaired the phone already. I even took it to a repairer and he couldn't repair it. He said, and IC have blown, therefore I need a new motherboard. But I didn't believe him; because I'm sure he didn't even look at the phone. Moreover, how can OS software (Marshmellow and Lollipop) damage hardware (IC)? Can that really happen?
[G3 Q&A, Help & Troubleshooting] ivomin:
I think you got some of the concepts mixed up.

1) QCOM mode is actually accessed through shorting the pins and thus gives you direct access to the memory using your PC. Your phone screen mostly likely be black/blank in that mode. Then using the QCOM tools on your PC you'll basically remap the whole memory - "copy" the needed data (ROM) in phone memory. In some cases this is exactly what is done at the factory. For QCOM you'll need to download the usb drivers and tools from QCOM.

The repairer usually does not have the software skills to do that and it is a lot more easy(and profitable) for them to just replace the whole motherboard with the factory memory....

2) blue/red LED flashing usually means that the bootloader ****ed up. Since the bootloader is hardware locked on that phone(and you can't mess with it) it happens that the next step of the boot can be messed up and should be ... well basically cracked if you want custom roms and stuff. If it's not cracked then you get security error(sometimes you don't even get that) for a few seconds then blank screen and just flashing of the led in blue/red.

3) Software can damage hardware by abusing it - upping the voltage on the processor, memory and so on.....

4) I don't think you have HW problem as usually if you have some HW problems you'll get blue screen (in case of processor or mem fail), bootloops, self rebooting, turning off by itself, software stalling, no life of it at all.......

5) Just let us know the exact procedure you have tried to restore it. What tools did you use, how you tried to enter download mode. What windows you are using.... just tell us as much as possible. Did you have taken out the battery... how long have you waited.....

6) I had the exact same phone and I have played with it for over an year... even managed to run pure console linux. I had to recreate partitions and reformat them many times..... unfortunately at the end it gave up with one last fall from my car holder to the ground (processor unsoldered - for my model(2014) it is known that it has a two stage soldering on processor and memory, one being soldered on colder temperature and when it goes to regular heating(processor heat) this solder get weaker and then one day you'll begin to have HW problems (blue screens, lockups....)).

7) Yes it has issues between the different versions. You can't use files from android 5 on android 6 or the other way around. Autorec is ****ed up tool for android 6. So I suggest once you manage to recover to original rom go with 30a... then root with kingroot, then use flashify and flash the correct twrp v3 (the img file) for that phone and then you'll be good to go with custom roms.

I do have all the tools you need(except for QCOM tools) but they are on my laptop (which I'm going to get back near the end of this month (october)) and you are going to need 32 bit windows 7.

Hi Ivomin

Answers to your questions at 5)

Using LGFlashTool2014 then gets to about 60% and a message saying; "the USB cable is connected to more than 2 phones. Connect the cable to 1 phone and press the 'retry' button." But I only have the (1) D858HK phone connected. Then I followed and tried https://xdaforums.com/lg-g3/general/unbricking-g3-d-858hk-t3365980 and by using (willcracker Board Diag) with 30a, then I see 45 rows of numbers/texts/symbols, after about 1 min. Then a pop-up/message saying; "Out of memory." Then I noticed 7 MBN files extracted to extract folder. My OP is windows 10 (64 bit).

I spent hours...turned into days...turned into months...trying to unbrick this phone; followed all instructions thoroughly but nothing works, while others with same model phone (even with black/blank screen) got their's working. Therefore, this is why I ended up taking it to the repairer in the end, but even he couldn't fix it (that was if he'd look at it).
[G3 Q&A, Help & Troubleshooting] ivomin:
As far as I understand you fail at step 7 where you used 30a TOT file. I think you should use KK TOT file or if you find other ways to extract it and use the already extracted files. I definitely think you should go from the base... go on KitKat and after you managed to end up as a stock then build up to 30a.
[G3 Q&A, Help & Troubleshooting] Soundboy:
Hi Ivomin

I can't find KitKat tot file. However, I also tried > 20d nor 30b but doesn't say whether KitKat tot files.

So far, 30a - 7 mbn files were extracted (win 10 64 bit) "run out of memory"; 20d - 7 mbn files were extracted (win 7 32 bit) "run out of memory"; and 30b - 10 mbn files were extracted (win 7 32 bit) "run out of memory". So, I got 3 more mbn files extracted with 30b than it is with 30a and 20d.

[G3 Q&A, Help & Troubleshooting] Soundboy:
Hi Ivomin! I tried the tools you sent me (by trial and error) as there were no instructions to show me how to repair my D858HK phone. When I tried to use LG Flash Tool 2014, the USB port detects 2 phones plugged in, then tells me to unplug one of them (when there is only one phone plugged in). I think I know the reason for this; it's because there are Lolipop and Marshmallow corruption on the same phone - so it's boot looping, why there is a black/blank screen and blue/red LED keeps flashing when the phone is switched on. It doesn't do so in download mode.

I managed to extract the 35 bin, 2 dll and D858HK10f00.dz files using WindowsLGFirmwareExtraxt, but I don't know what to do with them, because as mentioned...no instructions. I think maybe it's time to dump the phone because I'm sure it can't be repaired.

Also for custom roms I would suggest you mokee rom or crdroid or fulmics rom (updated stock 6). Those 3 are the best. Fulmics rom is actually original g4, so all lg tweaks are there (like double tap to wake, high quality camera and a ton of goody things)

Ivomin, you tried to help me in the past...; and I used all your tools in the folder and did as you suggested...but nothing works.

[G3 Q&A, Help & Troubleshooting] ivomin:
Ah yeah.... did you tried to use the qualcomm tools to access the memory itself. I have never done that but as far as i know it is through usb but you have to short a jumper on the motherboard....

https://android.stackexchange.com/q...uck-in-fastboot-using-qualcomm-unbrick-method
[G3 Q&A, Help & Troubleshooting] Soundboy:
Yes, I tried all that...including shorting the jumper. I think the phone may be booting in download mode using Qualcomm tool, but because the phone is blank/black, nothing can be seen on phone screen to carry out the rest of the tasks...
[G3 Q&A, Help & Troubleshooting] ivomin:
Ahh sorry to hear it then.... still i'm not really sure the screen should actually work in qualcomm mode.

Also almost an year ago I was looking for motherboard (as on mine the SoC unsoldered) and i decided that it didn't worth the risk and the money to invest in it since it was still possible that it would not work....
[G3 Q&A, Help & Troubleshooting] Soundboy:
After carrying out all the tasks... in download mode, using qualcomm tool, a message pops up on PC's screen informing me task... (on phone) has completed and I should reboot the phone. But as I mentioned; I can't see anything on the phone's screen to know whether the phone is rebooting or not. I believe the whole problem is the phone's blank/black screen, where I can't see anything that is happening...

I won't buy a motherboard anyway, as I understand it; it's just as expensive as the whole phone. And buying a used motherboard will be too risky...
[G3 Q&A, Help & Troubleshooting] ivomin:
Hm... If the flashing was ok I think then the problem may come from the display and not the motherboard.... there are some tools (but usb debugging should be enabled and i think it can be done through ADB..... actually no as you still have to have usb debugging enabled to execute adb command) that can share the phones screen through usb cable on a PC.... if you have time it may be worth exploring... you can also try inserting sim without pin code and try call it. If it rings then probably it's a display problem only.....

Motherboards go from around 50$ up (I think for a new once but it wasn't from the OEM itself...so....) and still it may **** up on trying to change the old one (which is quite hard as for some models the plastic sockets on the case are quite narrow and could damage some of the motherboard outer layers and additional devices (like the proximity sensor) - happened to me but SoC was already wasted so didn't cared much.

Still I keep the phone as I want to revive it sometime... it has sentimental value to me.... so if you stumble upon some cheap working motherboards(dual sim with 32GB memory and 3GB RAM )PM me ... next beer will be from me :P ;)
[G3 Q&A, Help & Troubleshooting] Soundboy:
OK; thanks for that... I'm not sure how to share the phone's screen through usb cable on the PC, since usb port doesn't recognise the phone using the phone's driver. As far as the motherboard is concerned...I'm based in the UK... But if I do decide to go for one, it may have to be from eBay UK.
