Rootkit on LG G4. Takes over my network and can't remove it. - G4 Q&A, Help & Troubleshooting

So last month I was following a tutorial on how to install ManageIQ. One of the steps involved pasting someone elses JSON on my google cloud account. That part of the tutorial was now changed with "generate your own private key".
Well, next thing I know my entire network got hacked, every single device too, my gmail account completely stolen, all passwords included etc. I didnt know that pasting someone elses Json key was basically giving access of everything to someone else.
The LG G4 was infected with some kind of malicious **** that as soon as I turn it on and connect it to my network, it opens my network to everyone.
The problem is ; I cant remove the rootkit because I cant root the phone. When I try to do it, I get a "this phone is from singapore and cant be unlocked" (?) message on he LG page, even tho its an International LG G4 H815 and shouldnt have this problem.
Yes, I already made several factory resets and using both methods (volume key down and by just doing it through the Opions menu), already tried with a brand new google account after one of these resets but still nothing. Same results. Today was ver obvious that the my phone was one of the issues because everything on my network was working fine until I decided to turn the g4 on after like 2 weeks..I wanted to check whatsapp.. And then I started to see random processes on my PC, ipsec, ssh enabled on my router, people getting access to the webcams of all devices (Im not joking) and all the nightmarish stuff Ive been suffering all this time. It came back once again.
One thing I noticed is that theres a ton of credentials that looks weird. Could someone with a clean lg g4 upload pictures of their credentials page on their phone? Also I cant remove all credentials because its greyed out.
Will upload screenshots of my credentials, later, so you can see and maybe tell me if something looks shady.
Solutions? Thanks.
EDIT: Here are all the credentials I got:
imgur . com / a / lA66Z
It gives me the option to encrypt and sd i dont have, altho I read this is a common issue.
I didnt take direct screenshots because im scared of plugging this into my PC right now so I just took photos. These pictures were taken right after a factory reset (low volume key method), just now.

Have you tried this?

Interesting. Would this work on a H815 with android 6.0?

Ok, installed using LGUP, refurbish option.
The certificates are still there tho.
Can I assume my phone is safe now ?

same problem

No security expert here, nor programmer, just a reader of these forums. But it seems pretty unlikely to me that you would have caught something that gets so deep into the system that it's still there after an lgup flash.
I have a bunch of things (about 40, maybe?) in the trusted credentials, too, so I guess that's normal?

After flashing the kdz your phone is clean if it was infected but! if you restore apps you may get infected again (IF it was a smartphone virus).
The trusted certificate authorities in your screens looking fine and the reason why you cannot remove them is they are coming with the android OS.
Your main problem seems to me your PC or PCs . I would run an offline antivirus scan with a boot ISO. I would do it in 2 steps. Step 1 would be to run the AV boot ISO scan on your system partitions only to see if it find anything. Do this with different scanners is highly recommended!!
If you found something I recommend to reinstall the OS! Cleaning is no 100% choice.
You should download at least 2 (3 are the top most I would use) of the free boot ISOs:
https://www.raymond.cc/blog/13-anti...-compared-in-search-for-the-best-rescue-disk/
You can make your life easier when using a method to make multiple boot ISOs e.g. on one USB stick:
https://www.raymond.cc/blog/integra...ne-single-disc-or-usb-flash-drive-with-sardu/
If you really do not want to reinstall your OS the next step is to scan ALL your data as well.
To be honest the above can be a VERY time consuming process and there will be still a risk that not every virus can be caught. The only chance to be clean is reinstall the OS of your PC. I assume it is windows so it may be the time to think about installing Linux instead the security concept of Linux is different to windows and keep in mind that 95% of viruses target windows systems.

KIN Two setup tool:SPST

I got a file and some apps & drivers.
You can find a PDF file in the attachement.
Please read it to see whether it can help.
Apps & Drivers:

Hi guys, here is another USB driver for KIN TWO which is a little bit different to the one uploaded above.
http-//rapidshare.com/files/456921463/KUSBDrivers.rar
( - should be replaced with : )
Thanks to every one here.
Let's work together/
This looks to be exactly what we are looking for. This will definitely open up the possibilities of modifying the current kin os, or porting a new os to the device. However, this guide is useless without the tools and files mentioned in the document. You said you had some files as well, do you have these files?
SPST Vn.n.n.msi.
PB10ZUnPB20ZU (Lab) Vn.n.n.msi.
SPSTUSBDriverInstall.msi.
InstallPMXMTP.msi
With these files we be able to finally successfully hack this phone.
This is great. We have the resources, now we must figure out how to get a modified os on the phone using the tools.
Awesome find KinPhoneLover; not sure how and where you got this SPST, but it could be the very thing that is needed. For people who bricked their kin phones, they should try the "refurbish feature" to see if that will successfully reset their phones back to "factory mode". As for getting a new OS on the phone, in the pdf at the "Upgrade section", when you browse for the firmware file, it is a .ecn file. Not sure how flashing is done for Cyanogen and those other Android custom firmwares, or their file type extensions. If SPST only supports/allows .ecn files, that could be a problem trying to use those Android custom firmwares.
wow, this is exactly what we needed....did this get leeked or something? it says its from the sharp corp., so im guessing they got it somehow by chatting with them? why isnt there a lot of buzz about this??? i can read my phone number and everything off of this...so close to getting android, or just putting java apps on it..
Too bad its only 32 bit But yes. This is one step closer. Please, people with brick kin, test it out. See if we can get the ball rolling again.

yes, i have to use my slow home computer, instead of using my quad core 64bit laptop
Just got everything up in running. Is anyone else having a problem with the SPST constantly dropping the connection with the phone and reconnecting? I'm not sure if this is due to running XP in a virtual box or if its something I can readily fix.
Short Answer: doesnt work.
Long Story: This needs your phone to be ON even for refurbish option and then, able to connect to a COM port. Unfortunately, that doesnt happen in SBL / APX mode and phone doesnt boot (autoreboots) so no COM mode available.
Just another software installed (for me).
No news in the front, guys. I guess i just need to get rid of verizon software (the one trying to get an OTA), not something from "normal" kin states.
Okay so now that we have a tool to upgrade the software all we need are custom firmware files to flash to it. However I don't see any option to read/dump the firmware using this software.
dezgrz seems to be correct, there don't seem to be a way to read/dump the current OS to make a backup of it. The PRL and ERI options don't seem to be what we want. The Provision option is the only option where we can read stuff from the phone. Could someone run that option, check all those settings (NAM1, security, feature, data, etc) and write it to a file and upload it? Maybe there will be something useful in there.
I gotta order a new battery, then I'll see if I can get anywhere with this... need to load up a 32bit OS first, apparently.
Either way, this is a huge step. Maybe not complete, but still a huge step. Thanks OP.
Hm..??
This seems interesting. I been watching this site until someone "Exploited" the phone. I have a mac, and does this work for kin? What does it do?

That features seem to be available already with "QPST" software... which didnt make anything advance (yet).
As i said, i renamed my NAM succesfully, and changed some security options (which i guess that doesnt matter, cause i *was* able to work anyway).
not much you can do that you cant do already, besides looking at your phones info. I was able to change voicemail numbers, was *86, i changed it to to just 8, and it says voicemail, but doesnt connect. Still playing around.
Why don't you just take it back to Verizon and get a replacement. How would they ever know you messed it up trying to hack it?

This phone needs to get hacked. I love my phone but i dont like the OS that the phone has. If this phone isnt hacked by the time summer comes, ill be glad to participate. I've hacked many phones but this may be a challenge. I would like to see apps on this phone.
PS I know the phone has java so where can i go to play games or apps for java?

[Q] Please help a Noob

OK. I think I've done my due diligence. I've scrubbed the forums for 2 days, I've googled it and I still can't figure out what I'm doing wrong.
Friend gives me this rooted LG OGP. Awsome! Works great! Then AT&T or LG sends an OTA update that bricks it :crying:. Read Aryan1312's sticky thread in this forum and get all pieces together. By now I have the 3.8.1 drivers AND the newest 3.10.1 drivers, LGFlashTool 1.8.1.1023, along with the newest 10P TOT file. I got the Flashtool to stop asking for PW and I think I'm ready to go.
But then . . . Plug my phone in and Device Management doesn't know what to do with phone. Reinstall drivers pack from LG website. Still no dice. Hmm. Phone is in Team Win Recovery Project v2.6.3.0 recovery screen (I guess that's what it's called) and computer doesn't know what to make of it. Hmm.
Maybe I can put it onto a microSD card and copy stuff over to phone? Maybe flash a different ROM through TWRP? Let's try that. I copy files over to the external SD card, put it into the phone, restart phone, hello TWRP, Advanced-File Manager option, WHY CAN'T YOU SEE THE EXTERNAL SDCARD??? Isn't it supposed to be there under /extSD?? It's time to ask for help.
Question: How do I get my Win7 PC to see the phone as a removable drive/external drive/whatever you call it so that I can get this info over?
I know that I have to change Port #'s after Win7 sees the phone. I just can't get there . . . yet.
- What I've tried:
Reinstalled drivers (both versions) and restarted between trying to plug phone in.
Tried installing phone drivers manually. Still doesn't mount as external HD as far as Win7 is concerned.
Called friend to ask his opinion. He doesn't remember and tries to tell me this is why Apple is "better".
Scoured the web to see what to do. Found articles about this same thing happening and all point to Stickied Post on this XDA forum
I did RTFM and am still lost.
---- Sorry for the long post, I just thought that people who wouldn't mind helping would appreciate the extra info.

1. Is the first pic with the phone connected to the pc?
2. If yes, have you tried to manually update drivers, while in device manager
3. I know that this is going to sound funny but have you tried a different USB port. The reason I ask is I had the same problem LG Optimus M and the phone was down for a couple of days. I tried everything and was about to call it quits but for some reason when I changed USB port the computer saw the phone and I was back in business. I am not saying that will 100% work but it is worth a try.

Yes I have. I think I did figure it out though. I put the device into "download mode" and my computer could see, and communicate, the phone.
To put my phone into "download mode" I did the following:
I connected the phone to the computer physically with USB cable
I turned phone off.
I pressed BOTH volume buttons and held the power button while phone was attached to computer.
With BOTH volume buttons still pressed, I released the power button.
The phone screen was black with a little dialog box in the middle saying "download mode"
I could then use LGFlash Tools to flash Stock AT&T TOT file back into phone. Took 519 seconds to complete the stock flash.
New problem arises, After flash, I do NOT have any 3G/4G signal. I can use the phone to make and receive phone calls and text messages, but I CANNOT use mobile internet unless I have it connected via wifi.
I installed the Debloated ROM and "tried" to flash 980 Baseband.zip but when I tried to install baseband, CWM gave me a permission error and said install failed. I haven't been able to use mobile internet since. Any help???
-- Again, sorry for the lengthy post. I figured that I might not be the only person who has gone through this. I see a lot of viewers to the thread so I think other people might be having same troubles as me.

It sound like you need to manually set the APN. Do a Search for your provider.. ie AT&T T-Mobile the setting is under Network/Tethering & Networks/ Mobile networks/ Access point name/ Hit Menu Button and New APN
You are the MAN / WOMAN!! Thanks for the help. That fixed it.
For posterity and to help another "noob" stuck in my case later (maybe months down the line)
This is what I've done up until now in plain text:
Used LGFlashtool to flash AT&T stock "10k" build
Went into Settings Icon>General>Developer Options>check off "USB Debugging"
Used "E980 Universal Root" from forums to gain Root access (verified with "Root Checker" from Playstore)
Used FreeGee to get TWRP recovery installed (rebooted into recovery with "QuickReboot" from Playstore).
Used TWRP recovery to install "E980 Baseband.zip" from forums
Factory Reset
Setup new phone and input APN settings (located in Settings Icon>Networks>Tethering & Networks>Mobile networks>Access point names>Menu button "New APN"/input carrier values/Menu button "Save")
Now that I know how to get back here, I'm going to scrap the stock ROM and try to do this whole process with a custom ROM. . . and another flash-a-holic is born. The learning journey continues.
Welcome:beer:
*KCCO*2SHAYNEZ*E980*
That is what this forum is for.
I have been helped out a lot from the group and I just thought it was time to pay it back. It is good to hear that you got it up and running. But one last word of advise BACK UP, BACK UP, BACK UP, and when that is done, back up the back up to the computer.

[Q] [x-post from LG G3] D851 unroot / restore to stock

I recently picked up a D851 (TMobile). I rooted it, but did not replace the ROM or install a custom bootloader.
Last weekend, the phone started randomly rebooting. Watching logcat via adb showed me several random apps throwing sig11s, after which the phone would give up and reboot. Cycle repeats.
This looks like a hardware issue, as the apps that crash change on each boot cycle.
I arranged with TMobile to swap the device, but they cautioned me that the phone must be returned to an unrooted state.
I've had a hell of a time with it from here. My first try was to install the LG drivers and the PC Suite under a Windows VM, as I do not run Windows at home. Enabling USB passthrough for the phone to the VM let Windows see the phone, but the LG drivers would invariably fail with 'Device cannot start. Code 10.'. Likewise, the PC Suite couldn't find the phone.
Next step was to throw together some spare hw and install Windows 7 on that (a desparate move, to be certain. ). The LG drivers can now recognize the phone, so that's a definite plus. The LG PC Suite, though, claimed that my phone could not be upgraded. Wonderful.
Next step was to try this tutorial: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html . I was able to get further with this method, but as it begins to flash SYSTEM, it pauses, and then dies with 'We can't communicate with Phone'. End result - I now have a soft bricked phone. On the phone, I see the port - COM41 - appear, and the usb animation starts to spin ... and after a few seconds, stops. It's at this point that Flashtool throws the Can't Connect error.
I next tried following this tutorial: http://forum.xda-developers.com/showthread.php?t=2785089 to flash a KDZ. The newer LG Flash tool used here can't create a connection to my phone for flashing.
I've run into a wall here. Any ideas on where to go next? I need to reset this phone back to a working stock state so that I can send it back.

Also - as silly as it sounds, make certain you're using the USB cable that came with the phone. This has solved problems for a lot of people when trying to revert to stock.

I wasn't initially, but I did switch to it last night. Still no go.
I suspect it's either the phone itself (see above: re suspected hw failure), or the PC in question (nVidia chipset on this old motherboard, and I've had more than a few problems with adb talking to phones on nVidia motherboards). I'm going to try Bacardilimon's suggestion tonight, on a PC that has *nothing* nVidia-related in it, before I throw in the towel. As it is, the failing phone needs to be back to TMO by the middle of next week, so I'm all but out of time to resolve this.

There is a link in the general thread on how to return to stock including a method using twrp. It's a sticky thread at the top I've never done the twrp method myself but it can more than likely be done without a computer. Twrp can be installed via Playstore if you don't already have it

Holy hell. That site's links are absolutely infuriating. Anyone who puts each and every download link for software referenced by a howto behind separate timed appearance links that you have to ALSO enter an annoying captcha to enable should be shot out of a cannon - or, at the very least, have their howto ignored by the rest of the world.
Suffice it to say, the quality of that page doesn't give me much confidence that this will work any better than what I've tried already. Since I've already wasted a crapload of time on this project, and more on following those damned links, I'll give it a try tonight, but I'm not going to hold my breath.

I'd consider doing that, except as I mentioned, the G3 in question disconnected during a run of Flashtool, rendering it without a working OS to boot to. The phone now boots straight to download mode. The good news is, it's now officially unrooted. The bad news is, it's also officially bricked until I can get an OS flash to work.

Yes he is a member and for every phone that is out their he has its own page doing this for us. If you can't fix your phone with his method then it not the method but you.

After going through the painful process of clicking his links, I found that everything I downloaded is the same thing I already had, except for Flashtool - lgg3root's is actually older. Even the TMO firmware for my phone and the dll are both exactly the same, and I checked by running md5sum on them.
But hey, it must be me. There's clearly no other technology-related cause for this issue. I obviously don't know how to follow a howto, right?
Thanks for 'keeping it real'.

Not likely.
In any case, it failed again. The video he did gave me the exact same steps I followed elsewhere, and unsurprisingly, it failed with 'We can't communicate with Phone', after beginning the flash process. There is something else wrong here, though I'm not certain if the failing phone is at fault or the PC in question is causing the issue. To be crystal clear, the flash process starts, and then, at a random point during the flash, it completely stops, and Flashtool eventually gives up and throws the aforementioned error.
Any other ideas? If not, I'm going to have to try another PC to rule that out as the culprit. Sigh.
Mine gave the same error as well as couldn't communicate with server but the flash process continued running and the phone rebooted took about 3 minutes u learned not to touch any of the popups on the screen during flash and sorry I missed the part about no OS I thought you were booting to recovery... Driving while reading not the best idea

Nope, the phone is definitely not doing anything - the usb animation on the G3 completely stops before Flashtool throws the error.
And damnit, quit reading while driving. You can do that later.
Moved the hdd Windows is installed on to another PC with a different chipset. After it updated drivers, I tried again. Flash proceeded partway, then died. Reset phone, Flashtool reststarted flash from scratch, flash died at 15%.
15% is interesting. While I've seen the flash die at various points, 15% is the one that was most often repeated. This tells me the failure follows the phone, not the PC - which makes sense, as the phone has a suspected RAM failure.
At this point, it appears that flashing this phone is impossible due to faulty hw. Hopefully TMO (and eventually, LG) will accept the faulty phone back with no OS, because there's no way an OS is being written to this device ever again.
Thank you for answering

No problem. There's nothing I hate more than stumbling across a thread where the OP has the same problem I have, only to find it was never updated with the solution.
Good luck man let us know what tmobile says

So you probably unlocked it to be used on other carriers as only the H815 can have an unlocked bootloader.
Just a small sugestion. Have you tried to create a new google account and sync with it to see what happens?
tried that and just tried it again with new account still in a loop. i unlocked the bootloader for root now when u unlock the boot loader lg remove warranty
anyone out there that can help.

Did you try clearing cache all google related apps like google service framework ?
what i have done is hardreset not sure how i can clean cache all google related apps like google service framework, as thats the only screen i can see i posted a video of whats happening, i have been on the pgone to google then its not them ring lg, i spoke to lg and emailed them a video waiting for a call back off them.
Maybe try booting into recovery in order to wipe EVERYTHING (and I mean everything possible).
Then boot back into download mode and flash the STOCK .kdz file (the one that your phone came from your carrier with, 10a/b which it was depending on how long you have had your phone).
If that does not work maybe try to build or get a custom AOSP Rom that does not have the GAPPS and see if you can just by-pass the issue all together by booting with having to deal with google apps (you would still need a work around for getting Gapps to work, but at least you would know exactly what the problem is and could boot into a working phone in the mean time).
Weird. Might be that 72 hour sign in feature (cough* bug *cough) thing because it looks like it might be kicking it back on the server side.
1) Did you try signing in on mobile data?
2) Do you have a nandroid, TB, or LG backup that you can restore?
2) Try bypassing the setup screen (keep tapping Next or Skip) and just get to the home screen. Then goto Settings ---> Accounts and add your account. This way you can get a usable device.
ive tried STOCK .kdz 10a/10b/10c
i dont have a nand backup
ive tryed using other wifi and my mobile internet.
google say its not them and im still waiting for lg to even look at the video they asked for..
is there any roms even out there for the g4 i cant find any. over a week now with out my g4.
AOSP Rom i wouldnt know where to start on building one i no longer have root or TWRP after flashing kdz
cant get the phone in adb mode developer as i cant get past the wifi screen as seen in video and cant get USB debugging.

Did you buy phone new, from where?
the phone is on a 24 month contract from o2 i got the phone from the carphone warehouse
ive just got off the phone to LG still not looked at the video they asked for i have been told to wait 7 working days WHAT thats gonna be like two weeks with a none working phone.
Weird, it's like you got a refurbished phone, and the old google account was not removed the correct way (remove google account before the phone is reset). If you reset phone without removing your account you get exactly what has happened to your phone. I see it all the time on the Nexus 6 forum.

LG G4 Bricked? Attempt to install alternate Mobile OS

Greetings,
General
I've been all over the Internet trying to gain access to more information about how to repair my LG G4. Well... Let's start from the beginning.
Story
I have an LG G4, it's old and I've had it for over 4-5 years now... I can't exactly remember how long I had it for. It still works, just needs a new battery and cable (cats chewed the cable and batteries don't last when you forget to disconnect them from the device, leave it plugged in for weeks and let it completely die for longer then a week).
I recently saw a video about the Pine phone and the fact that it was able to run a linux mobile distribution and when I looked into installing a custom OS into LG G4, it was possible... If I manually ported it myself.
I actually got fairly far using my Xubuntu system with configuring and compiling, the trouble I ran into was that I couldn't root or fastboot my device.
So, now here's where the problem began, I have a LG G4 factory reset and when I load up the Recovery mode, it brings up the android guy with their chest open and an exclamation mark in a yellow triangle, no message. After attempting to boot into recovery mode, I wait a little while and the phone automatically resets back to normal. When I use ADB to force the phone into fast boot, it skips it and starts the phone normally.
Now I'm on a mission to find a way to either fix the boot or flash the firmware (in hopes that it fixes the boot/recovery).
I have already tried:
Installing LGFlashTool
Versions, 2.0.1.6, 2.0.1.9, Year: 2014 and 2.0.2.5. Other than year 2014, the other ones were installed from LGFlashTool.com
Since Xubuntu can't run these files properly, I just ran them on my wife's Windows computer
I installed the LG Mobile Drivers and LGFlashTool had registered that it was the correct DLL but, it didn't seem to find the phone
Year 2014 LGFlashTool had found the phone but, I may have had the incorrect kdz file.
The Flash starts and the phone goes to firmware update, but the phone stops at zero and sits there while the program crashes saying that there was an error (in which no means to read, understand or locate the description of this error) and to try again by unplugging and removing the battery.
This version was downloaded from xda-developers.com
Conclusion
Once I can get into fastboot, I'll be able to root my phone and attempt to install the mobile OS I have ready.
Otherwise, I think I might be able to install a microSD card with the OS but, I don't think that will work if I can't get into the option to boot from a separate location (I believe that's called fastboot). But, then again... I think the phone needs to be rooted first... Then that brings me to the previous issue.
Details and Information
The phone details (as far as I see) are:
When I remove the battery I can see:
FCC ID: ZMFH810
IC ID: 2703C-H812
Model Number: LG-H812
I'm not exactly sure what KDZ file I got but the name is: PR H810PR10a_02.kdz, I also have the _04.kdz
I'm using H815 as my compile for the mobile OS, I may switch to H810 when I get back to that point.
Useless information: I still have the original leather backing... Removed from the phone because I didn't like it. If I find it, I can ship it to someone.
That's about it... I am very terrible about research and using Google properly (I have no idea why, I think it's a terrible flaw to have but, I have it). So, if you find the solution by typing words I didn't use or finding a similar post, I am very sorry. Hope I have everything posted here to help solve the issue, linking to posts that can resolve the issue or posting questions on what I might be missing will help.
Thanks in advance for the support of this community,

Well first of all you need to unlock your phone. H812 can't be unlocked officially though. Check my sig for the only unofficial one. Once unlocked you can flash custom ROMs but first of all you should read about ARB (antirollback) also in my sig and ensure you understand the risks all this brings. Gl.

Thanks for the positive feedback, I will attempt to fix my phone with your solution. This phone is technically almost garbage and when I fully update the phone, it runs like trash. So, if I can install a custom ROM, it may run a little better or have the tools I would personally like in a phone.
I'll let you know the details of my attempt,

Thank you very much with your support. I was able to unlock, bootloader and install the image installer.
I'm on the verge of compiling and installing Ubuntu Touch on my LG G4 H812.
Hope you guys proceed with everything you're doing right!
