So earlier today i received my phone back from repair, they replace the mobo. All seems good, phone works. So i unlocked the phone following this guide, same as last time: https://forum.xda-developers.com/lg-g6/how-to/official-lg-g6-bootloader-unlock-t3614719
It's a H870 and everything went fine. twrp boots fine, LG's USB drivers are installed and windows detects the phone fine. I wiped the phone entering "yes" trying to install fulmics. That didn't work as it bootlooped, so i went back re-wiped the phone.
I then tried to transfer stock [ROM][H870][Stock] OPEN EU LG-H870 10T ROM. It transfers 1.8gb of the 2.5gb before stalling, not getting any further and transfer eventually fails.
Right now i'm trying to transfer the LOS rom, but nope. Not getting any % and 5 min later the transfer fails.
I can enter bootloader and i can enter twrp.
So right now i'm guessing it's bricked. Searching the forums finds some users using something called uppercut but information seems very limited. Not sure what to do or how to do it.
Edit: So this is still a new phone to me, loads of stuff i don't know. So what i've done so far is using this unbrick guide http://www.android.gs/how-to-unbrick-the-lg-g6/
And i'm now loading H87010d_00_OPEN_EU_OP_0327.kdz through LGUP, and it appears to be working.

I already opened an RMA for the phone but they have no stock so I figured I'll take another shot at it.
The short version is that my gf messed up and updated the system while transferring her data from her old phone with the tapNgo thing.
I've done multiple facory resets, downloaded the rom from ZTE support, put it on SD, flashed it from recovery and deleted cache and nothing helps.
I don't have the exact error log anymore since I don't have the phone with me now but it reads something along the lines of
loading /proc/devices/audio/sound------ cannot find file/directory.
I looked it up and after a lot of Googling it seems like the symlink to the actual driver folder is missing and I have no idea why.
Does anyone know if i can fix this with an ADB shell?
Alternatively, I tried to follow some of the many guides out there to put the phone in EDL mode and relfash it with XiamiFlash utility but after trying 3-4 downloads and 900 versions of misflash all I ever get is "reading hello packet... unable to communicate to com4"
Haaaalp please?
*edit* this is pretty much exactly the same as what I'm getting: https://forum.xda-developers.com/android/help/sound-card-detected-t3379736
The problem with the phone is it makes no sounds?

Click to expand...
Click to collapse
the sound drivers for the OS is missing completely, no sound no microphone.
The syslog looks like this(this is from another phone its its the exact same problem):
AudioDaemon: Opening sound card state : /proc/asound/card---/state
AudioDaemon: Open /proc/asound/card---/state failed : No such file or directory
AudioDaemon: Sleeping for 100 ms
Strange issue indeed. Which model do you have? Which specific firmware file are you flashing to it?
I would think flashing the full unmodified factory firmware using the stock recovery will wipe the phone completely, including the /data partition.
Everything worked before? Help me understand the order of events. What is tapngo?
While in the midst of transferring information to or from the phone, a software update appeared and she accepted/installed it?
Its the A2017U model.
I had tried the 1.1.0 B15 firmware from SD card as well as the 1.0.0 B29 older firmware.
Right now its on B17 Nougat 7.1.1, the phone runs and works perfectly just has no audio hardware.
I wasn't there for the exact procedure but basically she powered it on, it asked for sim, she inserted that, tapped the "transfer my data" and then held the two phones together to get the NFC process started. That starts the bluetooth transfer process and it takes a really long time where it transfers all data and apps from the old phone.
At this point the phone still made sounds when adjusting the volume etc.
Somewhere in that process the "update available" notification came up and she pressed the option to install it.
After I got home I tried to figure out what is wrong, first i thought the phone wasn't registered on the cellphone network but then after a bit i figured out the audio is the issue, then i did a factory reset both from the phone UI and tried again from recovery mode, both times chose the "erase all data" option but neither time did it help at all.
I don't really know enough about phones but i think its the bootloader/something very early on thats messed up. Either that or the audio chip really just did fry.
My hope was to get the full factory image for everything that you need to install with the EDL mode thing but I can't find any good reliable guides for that.
It's the first thread in the development section.. Stickied even.
https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514
Get this package - B15-NEW_FULL (Nougat)
I really don't understand zte's numbering scheme. Newer versions get lower numbers. Makes no sense. That's the full firmware except for the fastboot which passes commands. At this point it's a non issue given the issue you're having.
So I don't need to load TWRP on it, I can still keep it just stock with unlocked bootloader?
I tried that miflash thing before, i had it connected un usb download mode but nothing worked for me, I'll try doing this guide when i get home step by step again.
Their firmware numbers is based on numbers and letters 1.0a-z and then 1.1a-z so 1.0z1 is less that 1.1a1
Ok I have an update
Did miflash, nothing changed.
Ulocked bootloader and miflashed the bootloader from the sticky thread.
The phone made the startup sound and audio worked for a few seconds after android started up and then stopped again
*edit*
ok so after it showed signs of life i re-locked the bootloader, and did the OTA updates to 7.1.1 and the audio seems to be working for good now!!
Conclusion seems to be the bootloader was the key to get it working again. Hope this helps others if it comes to it.
Ok so to start i got my bootloader code, did the Oem line in adb all went well, used the greatslon us M3 Twrp, said it went through ok, tried to boot using the volume up an down as well as power just boots to blackscreen then does nothing. if i let it just boot into factory android it runs for a min and then forces a reboot, oh and my model is the CPN-W09 which i think is the issue upon reading, the Greatslon twrp is for a dif version of M3 then mine, so i tried the erecovery it says im not supported, i tried restore through hisuite says not supported, i try and do a factory reset but unit powers off before it can complete. Any ideas what i can do?
I had that issue with my first M3, even though it's a BAH-W09. Since it was US version and I didn't catch there being a difference between it and the international/European BTV-W09, I screwed it up. I was never able to get back to full operation, but that was mostly out of irritation and the ease at which I could return it for a replacement.
That being said, there are full-update firmwares out there, you'll need to spend some time on Google/search engine of choice to find them. Once you have one, you'll need the firmware extractor to pull the update apart into the individual .img files, which can then be flashed using fastboot.
I'd start with https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146 - this is a firmware finder that should be able to find and download firmware updates for you (Windows only, I believe)
Then https://forum.xda-developers.com/showthread.php?t=2433454 - this should be able to pull the firmware apart for you. This was the part I got stuck on and initiated my return after, but I'm sure it works, I just wanted the easy way out
I'm in a bit of a pickle with my stylo 2 plus (tmobile k550)
back in 2016 sometime i rooted my phone and everything was fine and working properly, i was able to do everything i wanted to do. For a while now i've been wanting to restore my my phone back to it's original de-rooted state but the thread i went to for the rom indicated that if i used a tmobile phone it may sim lock it to metro pcs which i didn't mind and i took a gamble on it and followed the instuctions i used LGUP and installed it and everything was going fine even shows me the metropc logo/animation on startup but it gives me an error with the IMS that it was unable to start and i'd close the message and it would just pop back up and i was not able to do anything else. on top of that when i installed the rom i opted to not keep twrp installed . that was a mess that took me a better part of the day to figure how to get back on the phone but i cannot use LGUP with a proper KDZ file as every time i try to run it it tells me that my phone is a MS550 and won't install because the KDZ file is for a K550, i also tried LG Flash Tool 2014 and it analyzes the phone go up to 30% jumps back to 25% then says "Required info cannot be found." and just below that it says "Contact the system administrator.."
I've tried practically every suggestion i could find via google and youtube (man alot of those videos were repetitive broken records to boot)
if someone could please help me with this problem i'd greatly like to restore my phone back to it being seen as a k550. (i really cannot afford to buy a new phone at the moment and really like this one)
thanks for taking the time to read this.
Edit: I went into twrp and did a wipe and the IMS error is now gone and i can access the metropcs version of this phone but i'd still love to get the tmobile rom back on here if possible.
Edit2: After a little more searching I realized i am blinder than i thought and found another non-kdz stock installer for the k550 was able to restore my phone fully. thanks for anyone that stopped by and took time to read this.
I had a custom OS installed but didn't like it anymore. So I decided to return to stock.
I thought the most clean way would be to just flash a clean .kdz file through uppercut. So I backed up my stuff, downloaded an Oreo kdz and tried to flash it but got an invalid command response error. Since this point i couldnt boot anymore. Whenever I reboot with Volume Up + Power I just get into the Firmware Update Screen again. I've read that there might be slight differences between the versions of kdzs, so I downloaded mutliple others and tried to flash them aswell (All downloads were from lg-firmwares, which I considered to be reputable). I also varied the Android Versions because no Oreo kdz worked.
Since all of that didnt work I started to look for alternatives to LGUP + Uppercut. I tried LG-FlashTool which gave me an Error ("required info cannot be found" iirc), LG-Bridge doesn't even open up, LG-SupportTool says that upgrades are unavailable and greys out the reset upgrade errors option. At one point of the whole process I noticed that LGUP now started to say "please use latest dll" which was new. This Error now appears everytime when I try to flash somehting with uppercut, even after reinstalling or placing lgup_common.dll into LGUP/model/Common.
When I try to install a kdz just through LGUP without uppercut i get a "fail write backup partition" error.
Throughout the Process I reinstalled everything at least once and also reinstalled the usb-drivers multiple times. I now noticed that my Phone is not even recognised by adb. All of this problems are not limited to my main computer since I tried the same things on two other laptops. I also tried different usb cables.
At this point I am rather exhausted and have no more ideas. I don't know where i f*cked up, but I did.
What else could I try to get my phone to boot again? I'd appreciate every help.
EDIT:
Got it working. For anyone with the same problem: Just try it again and again. For me LGUP WITHOUT Uppercut and an oreo kdz worked after like the 20th attempt.
Hello XDA. I recently revived my G6 after it sat in my drawer for years and was delighted to see HavocOS on Oreo still running on it. I popped in my T-Mobile SIM and voila, service. My only issue was horrible data speeds. I tried every network settings and apn fix that is relevant to my device but I was still stuck with virtually no 4G data. So, my last resort was to flash back to stock. Now, I dont know if there is a specific method for this device as I forgot how complicated the root exploit was. But I went ahead and downloaded the latest stock .kdz (20g), LGUP and the drivers and proceeded as normal to flash the kdz over. I had SEVERAL issues getting my device model to be recognized and finally grabbed the right LGUP version that worked. I proceeded to flash the kdz when it gave me an error round 31%. I did much troubleshooting research and came up empty, finally decided to try flashing the stock version it was on (20a) to just restore it.
This worked. I thought I was saved until the phone froze on the T-Mobile logo while booting and didnt budge for an hour. Much more googling and I found a thread that looked promising and seemed to help. At first. It flashed the kdz, gave me the error, and when I tried to flash the dz, nothing. I retried LGUP with 20a stock, unknown model. I tried to go back through the whole rooting process again and stick it out with minimal service. The FWUL/lglaf portion of the guide is where I got stuck. My device would not be recognized in FWUL, I couldnt get wifi so plugged in my ethernet. And then I kept getting "USB configuration not set" and "input/output" errors, and I noticed that while booting FWUL, the step "Loading Kernel Modules" fails. So I assumed that FWUL was not loading any modules, including USB's (which explained the errors), so I booted up my own Manjaro install and cloned the same project there. Knowing all my modules work now, I still get the "Input/Output" error.
So now I'm led to believe this phone is hard-bricked. It registers as a port in Window's Device Manager, "LG AndroidUSB SerialNet" or something like that. I tried following the unknown model guide again to no avail. I'm at a loss. Whatever info is needed for debugging I'll provide. I'm dualbooting Win10 and Manjaro so any methods are viable.
Which specific stock KDZ(s) did you try to flash on your phone (full kdz name)? You need to seperate flashing and rooting as two separate tasks because from your post I can't tell if you are able to boot after flashing stock kdz or not. First, if your phone is not booting, you gotta recover from that and flash a stock kdz.
Also, try using the Dev patched LG UP from this post (thank the dev while you are there): https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
Try the 'Partition DL' option when you flash and select all partitions in the next window.
Once you are able to boot a stock rom, you can try using a VMWare such as virtual box, install/mount FWUL in a virtual environment and use that to root the phone. I think the process is somewhere here on the runningnak3d's guide or on another post, I will try find a link later.
