That unbrick guide worked for me on a D850 a few months back.

It's not easy to follow, beacuse the 2 pins are very small, and you need to plug the usb while holding them both.

Or try the method that was posted by BlackSoulxxx (http://xdaforums.com/showpost.php?p=64985005&postcount=967)

If you guys don't have access to Download Mode, you can't flash anything.

You have 2 possibilities:

- send the phone to LG for assistance

- try to follow a unbrick guide (like this: http://xdaforums.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359). But once you open the phone your warranty is gone.
[G3 Android Development] noidman123:
I'm shorting the pins guys. My phone is now recognized as Qualcomm HS-USB QLoader 9008 (COM3)
[G3 Android Development] noidman123:
Sooo I used the short pins method and i'm not having any luck so far. I'm sure it's cause i have a d851 because i saw a few posts mentioning it doesn't work with ours. basically the error i'm getting now is this (see attachment)

i'm sure if i can somehow get past this i can unbrick. i searched around the unbrick thread and there are no concrete answers, only to try shorting the pins for longer, restart the program/disconnect phone, uninstall/reinstall drivers, etc
[G3 Android Development] BlackSoulxxx:
No ETA pls.....
[G3 Android Development] vineet381:
I'm on Fulmics 2.7 and my device is F400K. Is it okay to do a clean install of this ROM, I understand apart from BT everything should suppose to work. Thanks!
[G3 Android Development] BlackSoulxxx:
I advised you to KDZ you device with LGE Official V30d for stable....

Ofcourse, if you like D855 international ROM and no Korea bloatware, then return to KK base, flash L baseband and flash the rom
[G3 Android Development] vineet381:
Thanks, I prefer the 2nd option. Dumb question, how do I return to KK base, flash any KK ROM I suppose?
[G3 Android Development] thatkindaguy:
Bro chill. It's ready when it's ready. It's disrespectful to ask for ETA's as it makes the dev feel under pressure. We lost the best dev for our G3 because of similar reasons.
[G3 Android Development] nhokcodon26:
Bluetooth fixed tomorrow
[G3 Android Development] BlackSoulxxx:
Sorry, but who are you anyway?

Great if you can fix bluetooth problems.....:good:
[G3 Android Development] Eagle-no1:
Did I understand correctly, this will be yet D855 version?

I'm just Finnish and slow to understand. :cyclops::p
[G3 Android Development] toanlaptop:
May he come from Tek Cafe
[G3 Android Development] BlackSoulxxx:
No, this is D855 ROM ported to other G3 version. Like switching an engine from 1 car to another car, same model but has different specs.....
[G3 Android Development] Eagle-no1:
Ok. Thanks :)
[G3 Android Development] vineet381:
Can anybody point me where I can return to KK base, flash L baseband before flashing this? I am on F400K.
[G3 Android Development] ramnoob:
Alright i am sorry its just i am excited for MM as Lp i buggy. Btw what does ETA mean? And which dev did we lose? Sorry to hear
[G3 Android Development] vineet381:
ETA = estimated time of arrival
[G3 Android Development] thatkindaguy:
ETA means estimated time of arrival. And we lost Cloudyfa.

com10

Did u change to com10? I see on your last post It was COM3
[G3 Android Development] noidman123:
yeah i changed to com 10, i saw a user recommend that there. still no luck

it's the no response error that's getting me. if i can get past that maybe there's hope

edit: and the device still shows the no battery sign if i don't short the pins so it's not completely unresponsive
[G3 Android Development] pacods61:
Maybe try com41

Try 41

---------- Post added at 04:56 PM ---------- Previous post was at 04:53 PM ----------

Do u have the qualcomm drivers installed?
[G3 Android Development] noidman123:
Still no luck on com41, same error. And yeah i have the drivers installed and to be safe i uninstalled, reinstalled then rebooted
[G3 Android Development] galaxyhero:
I need help with root. I tryed flashing supersu 2.52 and also latest and then it reboots but root doest stick. I am using ls990 variant. Other than that everything works fine for me.

i'm not sure if this would help anyone help me but i found a tool named lg smartbootdiag which created a log. maybe someone could take a look?

Bluetooth Issue
[G3 Android Development] JackSlaterIV:
The port number must be the same that your phone shows you in the devices manager.

Are you following this? http://xdaforums.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
[G3 Android Development] noidman123:
Yeah that's what i'm following. The thing is that by default it was on COM3 which didn't work. Then a post in that thread suggested COM10 which also didn't work. A few others suggested 41, which didn't work either. Sometimes when starting over it defaults to different ports. So far it's defaulted to 3, 5 and 8, but all of them give that error
[G3 Android Development] DARKCHYLDX101:
Stock Mm with Solid kernel running fine on my d850. Everything seems to be working. Haven't rooted yet. Liking the performance and new animations. Looks smooth. Battery life took a slight hit but not by much. Still last long enough for my needs. :)
[G3 Android Development] JackSlaterIV:
No, the guide is clear, you must use the same port. You have to find the cause that is giving you that error.

Read the thread more than once. Takes some time, I know.

The port 41 is used only to get Flashtool to work. Nothing more.
[G3 Android Development] Esevw:
Small update i have been running this on my D850 and everything is working good. Bluetooth connects to my wireless headphones no problem.

For people having data issues go check your apn settings. I had to a an apn for metropcs since i dont have att or tmobile.

Only problem I encountered was the grey virtical lines on the screen that a few people have mentioned, which i had to do a battery pull. Battery lasted about 12 hrs or so with 2 hrs or so of SOT. [/IMG]
[G3 Android Development] JackSlaterIV:
Thanks, can you let us know if you are able to go back to (restore) your previous rom without any problem? I didn't read any D850 experience about this. Thanks in advance.
[G3 Android Development] Subsonic44:
I've nandroided back to Fulmics 2.7 a couple of times without issue. Marshmallow working well so far!
[G3 Android Development] noidman123:
Hmm what i'm saying is that it defaulted to 3, 5 and 8 in device manager by itself, and i selected those in the tool and it didn't work. When i changed it to 10 & 41 both in device manager and the tool manually, it still didn't work. I'm trying to narrow it down but it doesn't say anything but no response from device
[G3 Android Development] JackSlaterIV:
The reason I asked is because I saw that the partitions included in this D850 rom are different from the stock ones (different md5).

---------- Post added at 20:07 ---------- Previous post was at 20:01 ----------

Try not using usb 3.0 ports, use the original usb cable, try using Windows 7. I remember these suggestions.

If you read the thread you'll see a lot of things that can go wrong. If you ask there you may get more help.

[MENTION=5733862]BlackSoulxxx[/MENTION] Thanks for reuploading VS985 v2 for us.
[G3 Android Development] zohaibkhan143:
There is an another board diag software which named as smart board diag and it contains all G3 variants for pass the chipset tests and I missed that software on my laptop. I found it on gsmhosting forum maybe that one helps u. If u found kindly post link here and try with that software. If that one will be fail then go for JTAG usb boot repair, Today I took my phone to the service shop for jtag he told me I will do it and he is charging 1500PKR which is 15$. I will got my G3 tomorrow and it will be fix hopfuly :)
[G3 Android Development] rippedwarrior69:
Please don't clutter up this thread with bricking issues. There are already threads about that. This thread is for this rom only.
[G3 Android Development] noidman123:
I have that software too, unfortunately all it does for me is create a log then disconnect my phone instead of fixing it. I'm gonna try and find a jtag repair service near me and if i can't i'll just have to suck it up and upgrade
[G3 Android Development] zohaibkhan143:
The bricking is caused by this thread so we will discuss here. If u don't have d851 then u r so lucky to having this rom on your device so plz stop making us more disappoint
[G3 Android Development] noidman123:
If OP doesn't want us discussing bricking issues he would say so, and I'd gladly stop. However the thing is that there's quite a few d851 users who have been affected by this, and getting the info out where others can easily see it helps prevent anyone else from making the same mistakes.
[G3 Android Development] TheLoonyRebel:
Quick question here.... when flashing the modem with Flashify do i use boot image or recovery image?
[G3 Android Development] noidman123:
neither, don't flash modems via flashify, as it'll try to flash to either recovery or boot, both of which might brick you
[G3 Android Development] rippedwarrior69:
Not trying to make anyone mad. I am using vs985. Just figure maybe this rom needs a q and a thread.
[G3 Android Development] rippedwarrior69:
Well i managed to get the 4g lte icon but data still says disconnected. I can send text and call fine. Still working on it lol.

In build.propt the line ro.build.version.incremental= just shows random numbers and not the actually modem name. Could the be a reason data not connecting? I have flased the mm modem and the lollipop bootstacks. Neither one change that line.
[G3 Android Development] TheLoonyRebel:
What should I do to flash the modem then?
[G3 Android Development] rippedwarrior69:
Use this http://xdaforums.com/showthread.php?p=56100153
[G3 Android Development] noidman123:
if it's a zip file you can just flash it via twrp. but ensure that it's a proper modem from one of the modem threads, and make a backup just in case
[G3 Android Development] louvass:
Do they have root for MM I'm on an 850

---------- Post added at 04:13 PM ---------- Previous post was at 04:11 PM ----------

I was able to as long as you have TWRP installed.
[G3 Android Development] TheLoonyRebel:
The modem is the VS985 one that is in the main post of this thread. I used the method posted but no go getting data on my VS985. :(
[G3 Android Development] BlackSoulxxx:
Try 35B modem instead.....
[G3 Android Development] rippedwarrior69:
I can get the 4g lte icon but data won't connect. The system select won't stick for me. If I change apn then data signal has x and have to reflash rom. Just flash 35b bootstack does help after that.
[G3 Android Development] megawayne:
Im using 21R modem for the D850. Should I be using something else? I have seen no issues and a better signal than the previous. Regards.
[G3 Android Development] yochananmarqos:
Would you share the 21r modem? I've only got 21q since I can't get OTA's on T-Mobile.
[G3 Android Development] megawayne:
21q and 21r are the same. I am simply quoting Yoshi_guy. I didnt extract it myself. Link to original thread below. He deserves the thanks if you use his files. Regards.

Didn't get data on 35B as well. Hopefully if a proper MM modem can be extracted from the beta MM VS985 release then that could help get this port working better.
[G3 Android Development] nickitnite:
So I installed did all the steps as in

http://xdaforums.com/showpost.php?p=64953015&postcount=782

Booted fine and had it working installing files SWEET MM here I come.

Next thing I knew it rebooted and now it is saying

"secure boot error!

Cause:Boot Certification verify"

I was going to try and go back o stock using the flash tool but that is not working because it says BIN Model is different.

Any ideas would be wonderful?
[G3 Android Development] BlackSoulxxx:
Use Bump-compatible bootstack and make sure that you flash in right order (Full wipe->ROM->Temp kernel->Solid->SuperSU(optional)->Xposed patch (Optional)->Xposed zip(Optional)
[G3 Android Development] Visionikz03:
LS990 here. Installation was a breeze and everything is up and running but I have no data at all (3G, 4G). Only Wifi. Option for Mobile Data under settings says "Not Allowed" and the switch is greyed out. Did I miss something somewhere? Even changed network mode to "LTE/CDMA" and still nothing.
[G3 Android Development] nickitnite:
I would try and re-flash it but I can't even get into recovery. I am able to get into Download mode and if I try and return to stock though LGFLash Tool it thinks it is a 855 when I try and push the 850 tot file. thought I could try and push the 855 tot but that prob would land m then I am now. Unless someone knows that the stock 855 tot I don't want to try it but

If I don't get it working in a couple days I may just try the 855 tot see what happens :silly:
[G3 Android Development] BlackSoulxxx:
1.Put the phone in Download mode and plug it into PC.

2. Use LGUp tool to flash TOT

3. Get d850 TOT, use Winhex to edit the first line of TOT file from D850 to D855 and flash it using LGUp
[G3 Android Development] galaxyhero:
I'm having the same issue as you and I can't get SuperSU installed either....tried flashing SuperSU in recovery several times but it doesn't work. I had to revert back to other rom since I must have data working because I drive and use Google maps all day.. SuperSU is less of a problem I really need data.
[G3 Android Development] nickitnite:
Going for it... I feel like such a noob but I've been useing computers for 28 years :p
[G3 Android Development] BlackSoulxxx:
Workarounds​

Kudos to all users who found this :o

Use 3rd-party apps to send SMS/MMS. Stock app is malfunctioned.

+Fix data on LS990: Long-press Data in quick settings, then choose Global - repeat on reboot. The 'Mobile Data' toggle in settings is grayed out.

+Fix adb not working: Use PTP mode, not MTP.

+Fix data on VS985: Set APNs then enable Roaming to get data.
[G3 Android Development] IamFlynn:

[G3 Android Development] nickitnite:
So LGUP only see's it as "Unknown" and won't let me go past model list. I used HxD and am not sure where you want me to change D850 to D855 or if I am even looking at the right thing.

Did you install all driver and also LGUp installed properly?
[G3 Android Development] TheLoonyRebel:
Fantastic. I'll hold off on any further work on data on VS985 until V3 comes out. Thank you everyone for all the hard work that's gone into this amazing ROM. From the time I played with it data issues aside it's very solid and smooth. I might jump ship to LG Marshmallow after having run CM13 and the like for awhile now I'm pretty impressed with this.
[G3 Android Development] auriculogenesis:
LOL. If you have TWRP, you could have simply flashed another ROM. Don't blame this thread for your incompetence. I literally just came into the Android scene a couple of months ago after using iOS since the 1.1.X days and even I picked up on that. I tested beta 1 on my device and it soft bricked my phone after I installed SuperSU using the TWRP prompt, but TWRP still worked for recovery. Search up threads on how to recover. OP already tried to help you as much as he could.

Yeah, you'll need to follow what OP said about the workaround below. Apparently this will be addressed in RC2 (eta unknown).

Looking forward to RC2! Thanks for all your hard work! Hoping RC2 makes data fully functional and I'll be able to use 3G lol. Sprint coverage sucks where I live.
[G3 Android Development] nickitnite:
So just change the first spot that is 850 or both? All the drivers are there all I get it this Unknown

If you have TWRP installed on your phone, you can just flash another rom. I had this rom on my D850 too and had to flash my old rom back because of the issue with Solid kernel. I just booted my phone back into TWRP and restored my backup. Worked fine. Didn't have to use LG UP.
[G3 Android Development] nickitnite:
Been trying to it won't go... Power+DownVol then DownVol and it comes up with the same Secure Boot Error... In the past I had been able to fix the issue when I used Multirom it gave me the same error so I just reloaded the rom.
[G3 Android Development] auriculogenesis:
You're experiencing an error that's strictly a Multirom issue... Hardly any of us are using that in here. You should seek help in that thread. They understand a lot more about that tweak than we do. I flashed this rom as my primary system. I have no problems with TWRP. I only flashed my stock rom because of the specific bootloader that I wanted. The best thing you can do is edit the stock rom as suggested by the OP and reflash it, I guess. Multirom sounds great in theory, but it's highly dangerous to be flashing multiple roms like that. Consider not doing it again in the future.
[G3 Android Development] nickitnite:
Well it is no longer installed that is why I am asking here. Oh well gonna use my S3 for a few day's till I get this fixed.... Sure if I mess around with it long enough it will work LOL
[G3 Android Development] auriculogenesis:
Gotcha. It's a bummer you're stuck in this position though. I've had a couple of cold boots where the screen didn't even turn on at all after flashing a rom, but after a few battery pulls, it worked again. Not sure if my RAM is going bad or something got corrupted, but it worked for me. Maybe give that a shot?
[G3 Android Development] nickitnite:
I decided to call it a night pulled out my old phone and pulled my sim (yeah I experiment on my daily driver :p) as soon as I put in the battery and decided to try one more time to boot it it loaded into TWRP..... Reloading the rom now lets see if I get the same issue. Thanks for your help

[G3 Android Development] yochananmarqos:
Out of curiosity since I haven't tried the D850 build just yet: Did you flash it at the same time as the ROM or after booting? It seems others have trouble waiting until later. Myself, I always flash SuperSU (if needed) at the same time as the ROM & have never had any issues.

Guys, pls stop hating each other. But auriculogenesis is right, this is not the appopriated place for discussing about unbrick and such. Soon there will be a moderator who will sweep this thread up. I suggests that you guys can create a thread in G3 General section.

Yeah, I acknowledged that my initial build of D851 screwed up very badly, infact I have to unbrick 2 devices when trying to debug it.... :/

Some asked me about US990/D851/D852 status. It's still WIP. I cant make any promises about it. But I will try my best...A fixed build for D851 is completed, anyone can try it? *Still very dangerous*
