So i really messed it up. I was coming from xdabbeb's vs982.5 and trying to upgrade to LP.
I rebooted before upgrading the bootstack to 39a. I believe I am on 27a still with LP firmware.
Upon powering up I get a boot certification error and a demigod crash handler critical error.
I have tried to kdz and tot back but both methods fail. I can reach download mode, but I do not have a custom recovery.
I was hoping someone can give me some insight into how i can fix this?
Thanks
Have you solved the problem?
Hello, a friend asked me for help unbricking his phone, apparently he downgraded to marshmallow, had some wifi troubles, tried to upgrade back to nougat and bricked the phone, the phone can enter fastboot and recovery mode but I can't flash the stock firmware because it gives me the verification failed message when trying to flash the files, I have been reading lots of tutorials but I can't get any of them working, when trying the blank flash thing the CMD window just stays in the waiting for device message.
Any help would be appreciated, thanks in advance.

If device is able to boot into bootloader, then blankflash will not work..
What is version of firmware you are trying ?
Currently this is latest firmware >> https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
Validation or bad key id errors are ignorable, ignore them.
Just make sure you get OKAY at end of Command..
If you get any error, post cmd screenshot or copy test and pasre here..
Hi guys!
Having this problem when trying to flash the custom back on my h870. So the story is that when I got the phone it was on android 7, then I’ve flashed msm, havoc and bliss, then flashed the stock android 9 kdz image using LG up, then went back to the custom roms. Now I am trying to go back to the same android 9 stock kdz but this time it doesn’t seem work anymore.
Phone is showing this error in the download mode console:
[msm8996] 633A B50
Modified / E / L / RO / id : 0()
LG uppercut showing this error:
Error: 0x81000302 Please use latest dll
LAF Protocol version is not match...
I can still use adb, fastboot and the custom rom just fine. It is just I can’t flash the stock rom back. Any help appriciated. Many thanks!
You need to find the Dll for LG v40 and the put it in the common folder of LG Up. If you still need help pm me.
Hi,
I was attempting to flash my V20 (F800S model) with LGUP and Uppercut some days ago. The flashing got to 12% then stalled and eventually timed out and stopped completely after an hour or so. Tried it again, and got the same result.
I then disconnected the phone from the PC and force-shut it off. Since then, I instead get the error 0x81000302 in various flavours when I try to flash the phone.
If I use Uppercut combined with LGUP, I get the message "Error: 0x81000302, Please use latest DLL. LAF Protocol version is not match".
I've also tried using LGUP alone without Uppercut, instead using a DLL for the device. I extracted the file LGUPc.dll from the KDZ firmware I was trying to flash with, renamed it "LGUP_common.dll" and placed it in the LGUP\model\common folder. Then, as I again ran LGUP, I got the error "DLL for F800S10e is not installed properly. Please install a DLL package (*.msi) for the model."
I then installed a common MSI-packaged DLL I found online and tried again. That gave me the error "0x81000302, AtCmdTxRx Error".
Any ideas what to try next? Since that initial flash failure, the device has been booting straight into the firmware installation screen, and can no longer boot into Android. Really hope there is a solution that could bring it back to life!
I was attempting to unlock my boot loader and flash a custom ROM, I was following a guide on YouTube specifically for this phone, and he was using US99610 firmware instead of Verizon firmware (to prevent uncontrolled vibration during 1st boot) I messed up the process and couldn't get back to TWRP, so I used his patched LGup tool to attempt to flash stock firmware back, because I could no longer use my phone's screen without connecting to HDMI and using a mouse and keyboard. I flashed it back to stock and everything seemed normal, until it didn't boot at all. I then tried to reflash the US996 firmware and LGup stopped at 4% with an error: SPC code does not match, please try again. Any ideas how I can unbrick it? If I connect it in download mode the tool still sees my phone fine, with the US99610 firmware on it. I can post pictures and a link to the YouTube video for further clarification. I've tried using patched LGup and partition dl to flash back, that's what throws the SPC code error. Any help would be appreciated
