After my m3 got stuck in edl I messed up my modem files ending in NV data error and unable to boot. I tried engineering rom to fix it but to no avail I still get NV data error on release rom. I'm asking for a twrp backup of modem partition for m3 or any suggestion on how to fix this.
PS edl bug is still present when my phone refuses to boot I leave it for a few days to drain then boot via fastboot.
PS I did find a strange hack to boot up the phone and that is to use engineering rom modem file, but then network does not work and also there is a strange looping effect when playing video files in any application inc vlc or Firefox.

Hey everyone!
While trying to update LineageOS on my G6 I somewhat messed up and now am out of ideas. I tried to install an OTA update, which sent me into a TWRP-bootloop. I tried to fix this by using the dd-commands described here before seeing the next post, which advised against it and recommended a different one. Unfortunately too late. I did back up both partitions on my external SD card, though.
Since then the phone is in a boot loop continuously displaying this screen (the author of this thread seemed to have a similar problem - but it wasn't resolved there). I can get into fastboot and download mode with the volume buttons. Getting into the reset-menu and trying to open TWRP from there doesn't work, it just goes back to boot-looping.
Do you have any ideas how to recover from this situation? Ideally without a factory reset... although I have most of my data backed up the storage is encrypted and It would be awesome to recover into the old system. I still have a little hope left that I haven't messed up quite that bad. :/
Thank you!
your data is lost because you can not do anything anymore
make full wipe with fastboot because LGUP currently update supports
fastboot format userdata
fastboot format cache
fastboot format system
go into download mode and flash stock with uppercut and LGUP do you get errors check drivers or take another stock rom. !!! you can not flash a US Stock rom to a EU Model (this was an example !) !!! watching exact your model [H870/H872/US997] and rom
For me it has worked successfully H870 with 20c open EU
Today I tried quartz 3 rom
with orange fox recovery and I have 2 backups of my old miui rom
after reverting back to my old rom I keep getting messages that Find device storage corrupted and Wifi does not work.
After clicking on wifi toggle it reverts back to off state not showing any available networks.
I tried different recoveries and even both of my backups also tried fastmood method and mi flash tool too still no worksround. Please help I can't find solution anywhere.
Ok I noticed that phone is booting haltway while using mi flash tool
Ok I solved it
The first thing you need is unlocked device.
Then boot it into EDL mode and flash through Mi Flash Tool

DId you find the solution?
I'm also facing the same issue, i tried to reflash using fastboot in mi flash, but getting error as
Writing 'tz' FAILED (remote: 'Critical partition flashing is not allowed')
Okay, Let me explain exactly what I did here... I first flashed Twrp using SP flash tool which worked without too much problem. Then I attempted to install the latest super su zip which told me the boot.img was already patched and it could not find a ramdisk... So I moved on and flashed the latest Magisk zip which flashed no problem. Rebooted the device and it came up with a red boot state telling me it would boot in 5 sec. It did not boot at all. Turned off the tablet and rebooted into twrp again. I then flashed the OTA update system.img, boot.img, and re-flashed twrp from twrp itself instead of the SP flash tool. It booted into twrp no problem, however now it said it could not mount the system partition. I did a full data wipe, factory reset, rebooted into twrp again. Same issue. So I attempted to re-flash the firmware with SP flash tool. Did not notice i had it set to format and download and not only download. It said formatting for maybe 2 sec and gave me an error. Now the device will not turn on at all... no screen whatsoever, no recovery, etc... I have had no luck getting the asus flash tool to even recognize a com port however SP flash tool seems to be able to flash the device no problem. I extracted the .raw firmware file I have for the latest firmware, modified the scatter file to allow flashing all partitions, and I did a full firmware flash of the device using SP flash tool. However it still does not turn on... it does nothing... So I'm assuming that I accidentally formatted over the bootloader... And I cannot find a bootloader flash file for this device anywhere... So I'm stuck with an Asus ZenBrick... Does anyone know a way to fix this issue? When I plug the device into my computer and open device manager it switches between the preloader and mtk serial port very quickly not staying on either one very long. I'm assuming this is why I cant get the asus flash tool to work and SP flash tool works off just the initial preloader. I just bought this tablet from someone and managed to hard brick it in less than a days time... Any help at all with a way to revive this device will be greatly appreciated. Thank You in advance to anyone who tries to help me fix my mess up.

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
