Hey guys. I've got a us998 with unlocked bootloader and twrp 3.2.1. I recently upgraded to 8.0 using kdz file from ChazzMatt's us998 kdz thread. I got the upgrade done, and booted into system. When I booted into twrp, it told me that data was encrytpted and I probably needed to do a format data which I did. After setting up the phone, I realized that twrp was still giving me the same issue. I tried flashing the no-verity and lg-rctd-disabler, but to no avail. I have tried factory data resetting the phone and it boots back into twrp. When I boot into system it boots to my current system. I tried reflashing twrp and got the same issue with encryption. Is there anything I can do at this point, or am I stuck with an unusable recovery.
I tried reflashing the 8.0 kdz using uppercut like before and it wouldn't have any of that.
Thanks ahead for any help offered.
Does anyone know if I can flash the nougat kdz, and then go back to Oreo? Can we do this on unlocked bootloader?

So I followed these instructions to root my LG G3 https://www.reddit.com/r/LGG3/comments/3qcctd/how_do_i_root_a_vs985_running_511_35b/cwe6756. Everything worked fine at first,I downgraded and rooted kitkat,then installed TWRP. After flashing the ROM,nothing displayed on the phone. The phone is booting,I can feel vibrations and hear the volume up notifications,but I'm having trouble getting into recovery. I'm pretty sure this has something to do with the fact that I accidentally flashed the cache after flashing the 9.1 rom,and that I forgot to do a factory reset after the first one. What should I do now?
Can you put it in Download mode? Even if the screen doesn't display anything, you can tell that you successfully got it in Download mode by looking in Windows' Device Manager. You should already have installed the Verizon LG drivers, and preferably rebooted the PC, give the PC up to 10 minutes to load the drivers the first time you connect the phone in Download mode via a USB 2.0 port and with the original cable.
If you get it in Download mode, use LG Flash Tool 2014 to flash the 10B KDZ to make it easiest to root and put TWRP back on.
The problem definitely didn't have anything to do with not doing a factory reset. As long as you had wiped Cache, Dalvik/ART and Data.
By "flashing cache" if you mean wiping Cache, no, that shouldn't be the problem either.
JasmineROM 9.1 is just an update to 9.0; had you flashed 9.0 before 9.1? If not, then that's the problem.
What exactly do you mean about a problem getting into recovery? Do you mean you can't see that either or what?
I managed to get it fixed Since the phone was still working I was able to take screenshots of everything I was doing while hooked up to my computer until I could use Flashify to reboot into fastboot,then repeated the steps to downgrading using these instructions https://www.reddit.com/r/LGG3/comme...phone_stuck_in_factory_reset_status_2/cmlm3wo
It probably was getting into recovery and I just didn't notice since nothing was displaying,but its all working now,and I successfully flashed CM13 instead.
Here's my custom xTreme rom in the making for T-Mobile's 8" LG G Pad X.

Must be at least 20f/g with TWRP to flash this.
To get TWRP go here: (Kdz to 20f if on 20g)

Flashed this just after following jdub01984's guide to update to 7.0, but ended up with a bootloop (not a twrp bootloop). Had to hard reset to force factory recovery. The build was at 20f before I installed, and I most definitely did not format system, just booted twrp, backed up, installed the rom, wiped cache, and rebooted. Install glitch? Should I try again? Was starting to panic when no combination of key presses seemed to interrupt the loop or cause a power down, then I found the hard reset sequence which got me back to twrp so I could restore (I'm using twrp 3.0.2 v2).

Sounds like a bad flash or download.

Yup, was a bad flash. Repeated the same procedure and it worked! Thanks! :good:
@micromod 777 What are the chances of you updating this rom to the latest firmware? Has been my go to since you released it.:good:
Ok... So...
I installed fulmics through TWRP and all worked great
After that, I installed a v30 Rom also with TWRP and that worked great, too, but i decided i like fulmics more and wanted to go back
Retried TWRP and kinda worked, but some errors were popping up all the time, so i decide to reinstall it
Now here i am. When it boots, goes straight in TWRP. I tried a stock zip to flash with TWRP, no luck.
When in TWRP I can see the phone on pc, internal storage in empty.
Fastboot works.
When i load up LGUP, under the version tab, it shows fulmics mod and i can't take any action
How fried is it?

Try doing a complete wipe, wipe cache, Dalvik, data, system. Then wipe internal storage via the format data option and reboot recovery. I am guessing that you're on the h850 variant so Flash the 20s complete firmware zip then flash SuperSU or magisk. See if it boots into system.
I do still suggest hooking it up to your PC and flashing stock firmware kdz 20s using uppercut. If if it is recognizing fastboot commands then you should have no issue flashing a new recovery image after you load the stock kdz, you may even be able to flash a new recovery image instead of going through all the other steps that I listed. Which may some your issue. But it's best to format data entirely before flashing anymore ROMs, and use lgup via uppercut to flash stock firmware and let it boot entirely before reflashing fulmics.
But formatting data is key to reset the system folders which were leftover from other ROMs and likely the cause of the issues you experienced.
I thought I could factory reset my phone since I couldn't install any apps for some reason, I did it through the OS and not twrp and after that it would only boot to twrp. Then I thought I could just flash a rom through twrp, all it said was that it was done and successful, but it would still boot into twrp. After that I thought I should flash kdz with lgup but whenever I go into download mode it reboots after about a minute. I am not very experienced as you can tell, please help.
Before this, I had rooted my phone through this tutorial:
https://forum.xda-developers.com/tmobile-lg-v10/general/root-h901-nougat-t3773942
Phone is a frankensteined LG V30, 931, I installed Lineage on it following the correct steps for prepping the phone for an AOSP rom.
I had some issues with Lineage and decided to restore from backup, but when I restored my phone it hung on the splash screen permanently. I factory data reset, no good, still hung.
Wiped everything in TWRP and flashed US990_H, booted up okay but now I'm bootlooping.
Went back into TWRP and wiped data, restored from my backup, rebooted, still bootlooping.
Went back into TWRP, wiped everything and flashed US998E, F, G, H in order, rebooted, still bootlooping.
I'm out of ideas.

What TWRP are you running? 3.2.3.7 stable from WTF?
What Magisk are you on? 19.x doesn't work well flashing TWRP flashable zips. Boot back into TWRP, uninstall Magisk and install 18.0 or 18.1.
See if that works.

Worst comes to worst, you can go into Download mode, flash 20H in Refurbish mode. You're back on pure stock, but still have unlocked bootloader with fastboot flash commands. Reinstall TWRP, flash the three root files again (no encryption, no root check, Magisk).
But then you'll have to manually install some stuff Johnfawkes puts in his TWRP-flashable zips.

I was on 3.2.3.7 from WTF, yes, and 19.x, that must have been my problem. I having the idea to refurbish flash 20H myself, and did that successfully. Going to go ahead and get started on installing the other files now. And doing a full system-image TWRP backup to prevent this from happening in the future.
Out of curiosity, what does Magisk do that causes this to happen? I would have thought that once I wiped the system and data partitions magisk would be gone completely.
i have a similar issue going on here and i'm stuck. bootlooping directly back to TWRP regardless of command (bootloader, power off, system). i believe i took all the right steps in WTF thread (unlocked, rooted, updated to latest H FW) then tried to flash lineageOS. even my sequential (unlock, root, update) TWRPs wont boot (they restore properly it just boots back to TWRP). i tried reflashing E,F,G,H no go.
US998, used proper 3.2.3.7 TWRP, Magisk18.
i've been flashing phones for years and this one has been difficult. any help?
EDIT: it seems the aroma installers of gapps was crashing TWRP. i was finally able to get back into bootloader and upon re-flashing TWRP everything seems back to normal. i can also recreate the problem so its def a gapps/TWRP no likey situation.
I think I ran into that once, and I powered-off fully and booted manually and it worked... you could try that. I may have even tried booting into bootloader or something, and then that fixed it too? I forget exactly, but it wasn't too big of a deal, once I got it solved, of course!
