Hi guys,
Few months ago, I've noticed reveal of Nougat ROM update on this forum and I went for it.
But then...
I tried to root my phone with KingoRoot, it crashed on 80%. Any other software has this error.
I'm unable to do anything about software update or so. Anything I do is missed hit. No results at all.
I don't want to format my data on phone, because I have too much important files there...
Also, my phone is invisible in My Computer when I connect USB.
I want to update my phone, but I can't - please help me urgently!!!!

Hey xda!
I rooted my phone 2-3 months ago, and regretted every day since!
I tried the guide on the forum, but i may have done something wrong.
Because it is still rooted, not with SuperSU, tho with TWRP.
Its not that the fact that my phone is rooted irritates me, its more that, i cannot update from kitkat 4.4.2 to kitkat 4.4.4.
and my Phonenetwork Signal & 3g/4g network connection is lost every 20-30 minutes.
When i am trying to Unroot, it is necessary to find my model number with the CMD. This worked for me the first time, but at that time, i couldnt find the right stock recovery backup. But now i cannot even see which model i have, because my device is never found using the developer kit tool.
I dont know how to do it, and i am very sad that i spent so many money on such a good phone, and then i "corrupted" it.
I dont know if somebody has an Easy Fix for me. i dont think so.
But if somebody knows how to do this, i would happily send it to the person who have courage to try Unroot my phone!
I will pay a fair wage for the process. Tho, HTC repair center offered me to change my internal storage and motherboard for bout 200euros.
I hope there is a superHero out there! :good::good::good:
best regards

First off, your understanding of what root does and means seems shaky at best. Root is just a permission change. Nothing more, nothing less. Root does not affect signal strength. Something else is going on there, that has nothing to do with root. Updating the phone might help, might not. I don't expect a drastic change in signal issues from OTA updates.
Root will also not effect the USB connectivity to your computer. This may be due to USB ports or cables; or very frequently just an issue with drivers. It too has nothing to do with being rooted.
Root in itself will not prevent OTA, although having custom recovery installed and/or any system files altered by root will prevent OTA from installing. But neither will prevent OTA notification and download from occurring. The more pressing issue, is that if you did not receive and/or able to install the 4.4.3 OTA, you won't received the 4.4.4 OTA either, as they need to be installed in sequence.
My advice is to troubleshoot the USB connectivity issue. Once you have that figured out, get CID and restore the stock nandroid and recovery. This will hopefully force the 4.4.3 OTA, then the 4.4.4 OTA.
Ty for your reply - but its not exactly what i meant in all ways.
Its not that the USB connectivity isnt working.
My pc can transfer, edit and read files from and to the HTC phone.
Its just that it cant seem to find the CID, because i did something wrong in the unrooting process.
I dont know much about all of this rooting, as you said.
Tho, I did not have any problems about my phones network connectivity, until i rooted my phone!
Im almost hundred procent sure, that this is some kind of software bug, because it has perfectly signal strength everywhere, its just that, some settings, makes it reset my phones 3g and network connection every 20 minutes or so.
Its like its going on airplane-mode, and then shortly comes back to normal.
to begin i thought i made some stupid settings on it, but then i looked all settings on the phone thru, 600 times, and couldnt find nothing!
Thank you for your reply.
I hope somebody is familiar with both of my problems:
1. cant find CID, because im stuck on some step of the unrooting process.
2. Resetting my network settings automatically every 20 minutes or so. (in short)

That doesn't prove anything. You can have MTP connectivity (internal storage access) but broken fastboot and/or adb connectivity. I've seen this many times here before.
adb/fastboot not finding the device is almost always a matter of connectivity (usually a driver issue).
If you have HTC Sync and/or HTC drivers installed, try to uninstall them and see if this fixes adb/fastboot connectivity.

Rooting doesn't affect the phone's performance or signal. Period.
If its a software bug, it must be due to some mod your applied, or some app you installed. I assume you must have applied some mods, or using a root app, otherwise why did you root?
And are you sure it isn't just a carrier network issue?
Hi all. I'm posting here because after countless (2) hours of searching online I haven't been able to find a proper solution for a problem. I'm hoping that you all can help me with this one.
I've been using the LG g3 for the past year and everything has been great. But since my screen got smashed I've had to replace it with a newer one. I got this last Thursday.
I've been sticking with stock because I'm quite fond of the stock marshmallow. But since I'm a tinkerer I can't help myself. So after I updated (yesterday) I was going to attempt to root and flash a shiny new rom. Unfortunately, I haven't been able to get that far, as my phone can no longer be recognized by my computer.
I will put it in, and it will pop up with "USB Device not recognized". Under device managers it merely shows up as "unknown usb device". So I uninstalled my LG drivers (which are normally installed once you plug in the phone, but I digress. It did all of this before the 6.0 update) and it will attempt to install usb drivers but fail almost immediately and say it experienced an "unknown error", very helpfully reminding me to try and unplug/plug the device or factory reset.
Factory reset is very difficult for me right now as I have just finally gotten the phone tweaked to my liking. I really don't want to have to re-download everything. I have tried almost every workarounds I could find on the Internet but I keep running in circles. I've downloaded several different drivers for my phone and none of them work. I'm really at a loss.
I'm assuming that it must be the marshmallow update, as I haven't rooted or installed cfw as of yet. And I can plug someone else's phone in and it will install the drivers in a heartbeat. I can charge my phone but it won't give me options for MTP/PTP/Charge mode at all.
Anyways that's about all I can ask at the moment. I just hope someone here has experienced this and knows what to do.
Okay, I have now tried factory resetting my phone and it still won't work. It's the 6.0 update that's causing this. I'm at a loss, either I have to wait for google to hopefully patch this or I have to take back my new phone and exchange it for a new one.
You should be aware that the correct model number for a Canadian G3 from Koodo is D852, not D820 as you mentioned.
Before taking back your phone, try to see if your phone is recognized with a different USB cable (OEM one preferred), plugged in a different USB port of your computer, or, if possible on a friend's Windows 10 or Windows 8 computer, just in case different drivers might recognize your phone.
Your suspicion (that the OTA update to MM caused this) is not well supported by the reality: the OTA update was quite uneventful for thousands of other Canadian G3 phones; we should have heard more complaints if the OTA update were botched by Koodo or Telus.
Hello everyone i am in desperate need of help to fixing my g3... Out of nowhere it just stopped working and got stuck on the lg life is good screen.
I was able to access TWRP but i wasnt able do perform a factory data reset of any sort becasue it said that theres an error in mounting the internal storage, data and i believe cache. I then tried to community based unrooting process which uses a program from 2014 called the lgflash tool (youtube) and after getting about halfway through all the steps it just gives me an error saying that the software couldnt be matched or something like that. What else can i try? i am not in the market for a new phone right now and it just sucks that nothing is working. ive tried it on windows 10 and 8.
ANY HELP IS APPRECIATED!
You can try to use LG PC Suite IV available on LG's website. It will install the latest firmware on your phone
Hello to all,
i'd require some assistance, if anyone is so kind to help me. I'm not a pro, neither a noob in this kind of things, but i'm encountering some problems.
My telephone is:
- ZE551ml - ASUS_Z00AD
- Android 6.0.1 Marshmellow, security patch: 5 April 2017
- Build: MMB29P.WW-ASUS_Z00A-4.21.40.327
- IFIW is 0094.0183
I'd need just to root my phone, then move one app as system app and then unroot.
when i run this toolkit, having installed drivers, connected device, debug usb on, and i try to unlock bootloader, the program tells me that i require further files and it downloads them, also if i had already downloaded them from this site and added them to resources folder. After that it says it has extracted them and to retry to start the unlocking bootloader process. The problem is that from this point on, every time i start the unlocking process, it just continue in a loop telling me it has extracted and to retry, and then again, and so on.
before finding this toolkit, i had tried some other ways, included to unlock bootloader, using the official asus app, that anyway crashes every time, just after i finish to accept the conditions. I recently have done also a factory reset, to see if something was messed up and would have restored, but the problem persists.
i hope that a kind soul would give me at least some hints to follow, and that isn't just my phone problem.
Thank you in advance guys.

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!
