Hello, my SM-G935A is rooted, and I have 2 issues with it. Firstly, I'm unable to receive texts or phone calls (I can send them), and I've tried a factory reset and I even got a new SIM, but nothing worked. I think if I flash stock firmware, it might fix the issue. Second problem, when I go into download mode and select my AP in Odin and press start, my phone gets an error and Odin freezes at Initialization.
Any help would be appreciated. I would prefer to fix the texting issue, as I don't want to return the phone to ATT. In either case, the Odin issue needs to be fixed
I'm having a similar issue. This afternoon, 2 apps threw errors and closed. I rebooted, which apparently was the wrong thing to do. The reboot stalled on the AT&T logo and stayed that way for 5 min - the unit became very hot & the power button did not respond, even while holding it down. I got into recovery, cleared the cache and factory reset, then rebooted. The unit came back up and started reinstalling everything. I took it back down into the download status and attempted to reload 935x via Odin, only to stall at "initialzation" [sic] as you did. I got out of that after waiting for some sort of response. SuperSU was still in my apps as was Root Checker. Root Checker indicates the system is rooted. SuperSU indicates it needs the binary updated. BusyBox and TiBu indicate they cannot find root. I deleted all the root apps and tried reinstalling root via adb which completed successfully, but the same outcome with all the root apps. So I'm not sure if I'm still really rooted as Root Checker claims, or not.
EDIT: I just saw that I have 2 "Knox Settings" apps. Clicking on either returns, "Unfortunately, Container Agent2 has stopped."
use the odin from the stock firmware thread to flash it again. if it fails you can flash the u firmware and then the stock again. then you have to use a different odin if you want to flash the root api file the one you flash the firmware with wont work. also there is help in one of the threads about fixing the volte problem so you dont have to turn it off to get calls. i didnt have to do it as using the odin i mentioned fixed it for me when i came from the u firmware.

I was having the exact same problem you had with Odin. It seemed I was able to flash stock firmware using this version of Odin: http://www.mediafire.com/download/2t2sjqxtogbkafk/odin_3.12.3.rar

did you have any problems with the u version of the s7 edge firmware, like the fingerprint scanner not responding? i am on that version and cant get any odin version or any version of s7 edge g935a firmware to flash, tried unrooting and was forced to use the U version of the s7 edge firmware, everything works except the fingerprint scanner, cant get back to full stock firmware, need help!
im having the exact same problem, when i put my phone into download mode and flash the stock at&t firmware, Odin get stuck in "initialization" and my phone screen displays and error message.
Same stuff was happening to me, I went back to stock and took the update. When your phone stops working as an actual phone, it's time to roll it back.
I played with it for a week and my phone was so freaking hot (with hot weather) equals a wait and see if this gets more stable in the near future. I did use the Odin 3.12.3 mentioned by King James III. Honestly, I did so many things to get it back to stock I forget what actually worked (it was the wee hours of the morning and I was spent). Don't give up guys, it will and can work.
edit: It may be as simple as not right clicking Odin and running it as Administrator.

I used Odin_v3.12.3_Patched_SHA256 to flash the 935U Firmware then used Odin3_v3.11.2 to flash the June Firmware release.
I have an LG Stylo V2 plus and I unlocked the bootloader a few years ago to play around with it as it was a spare phone. I pulled it out a few days ago and found a warning about it being corrupt and could not be trusted. I am now stuck in a boot loop where it will load to the Verizon loading but then spin there forever.
I installed all of the necessary software and tried to dl the firmware flash files that are suggested on all guides but LGUP throws an error either that the file is bad or that there was an issue with the update/refurb.
I installed LG Bridge but it was pretty useless without a restore file to restore the phone to (not to mention it could not detect the phone where LGUP did).
Also the only source of the firmware kdz files (the only source I can find lg-firmwares.com) seem to have a limit of like 90 KB/s dl rates so these 1.5 GB files take all day to dl and then don't work.
Every guide I can find here on xda for the boot loop says it can definitely be fixed and that its a soft brick (since I can still boot to the download mode). But then they don't seem to actually guide you in any logical path to fixing it other than doing the same LGUP that seems to not work.
I went to reddit to see if I could talk to anyone about the issue and was sent here by a bot and my post was removed.
I hope someone can help. If you need any more information I am happy to provide. All I am wanting is to just factory reset the phone so it works again.
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.
I have an H872 on Havoc 4.4. I have upgraded to a Pixel and will be giving the H872 to my father-in-law. He will only be using it for phone calls - very unlikely he will text, and definitely won't use data. It will also be his first smart phone. Since the H872 is rooted, when it boots up it gives the warning display that the phone may be "Corrupted". I don't want to have to explain all that "root" stuff to him, etc... I want the phone as basic and simple as can be, hence , I want to reflash the stock firmware.
I am having troubles though. Booting the phone into download mode and starting LGUP fails to recognize the phone. I've tried with Uppercut as well and it says I'm missing a file in Apps/Roaming, etc...
Not sure the problem because I have reflashed stock many times with LGUP. Could it be that Havoc has changed the "identity" of the phone, or that it's on Android 11?
Any help to get this back to stock is much appreciated!
Got it figured out. Flashed back to an older TWRP (was on Orange Fox), flashed an old stock Oreo ROM, and then was able to flash kdz with LGUP.
