Us996 TWRP not sticking

[lowsnamebrand]

I'm using the tutorial on the LineageOS wiki for the Us996. I've unlocked the bootloader via official means from LG, but when it comes time to send the recovery via fastboot, it successfully sends and writes it, it even let's me boot into it, after pulling the battery, and using the correct button commands. But if I restart and try to enter again I'm greeted by the official erase everything recovery.

Does anyone know what I'm doing wrong? Do I need to flash root to get the recovery to stick?

Take a look at this video. If you have TWRP installed right, and are going to it through a battery pull and the power button volume down combination, then the screen that comes up looks scary and looks like you'll "format" your phone, but as you see in this video, you don't.

See I've gotten into TWRP, then I reboot system(actual Android not just restarting recovery).the problem is When I power off my phone and tried to get back into TWRP, I clicked yes and yes and it proceeded to wipe my phone. TWRP wasn't there just factory reset lol

Not sure why it isnt happening automatically (it usually does when flashing things like magisk to root) but when you get into twrp or with root rename /system/recovery-from-boot.p to /system/recovery-from-boot.bak. If in twrp first go into the mount page and uncheck the box at the bottom that says something about system read only first, then you can use the file manager.

Or since it sounds like you want to flash lineage, just flash the lineageos zip (and then optionally opengapps and root). Be sure to format data too (wipe->format data->yes). Then if you dont have lineage on an sdcard ready to go you could reboot recovery so that the formatted data is ready then connect to pc and send the zips over by using adb push C:\path\to\lineage.zip /sdcard/

What I'm thinking about doing is flashing TWRP again, on first boot(of TWRP) backing up my current rom(stock) and trying to boot into recovery again, because if it doesn't stick again, it'll wipe but at least I'll have a backup.

I've noticed a lot of different root files which would you recommend?

Sorry for the double post but does the "LG factory reset" stay even after having TWRP installed? Like will I always have to answer yes twice to enter TWRP?

Yes thats always the same.

If you don't flash lineage or something to root stock (I reccommend magisk since the alternative, Supersu, is owned by some Chinese company, and magisk has various modules that do many things) and don't rename /system/recovery-from-boot.p manually (theres a file manager under advanced in twrp) the stock rom will use that file to reflash stock recovery any time it boots.

Awesome I think my issue is not renaming that file and the stock rom reinstalling stock recovery. I've used SuperSU, never used magisk, is there a stickied release thread for it?

You've been a huge help, thank you! I'll report back later tonight, when I can actually work on my phone

So i was able to obtain root aswell as installed twrp, the only issue I had was every rom I tried refused to boot. They just hung at the loading screen, that includes the back up I'd made of stock, is there something I missed?

If you mean the boot animation, the very first time can take a good while, like 20 minutes. Also make sure you've formatted /data if you havnt yet especially going to lineage.

Sorry for the late reply, yeah I think I just let the boot animation go for around 5, I'm gonna have to try reflashing it and hoping for the best, I'll be sure to answer back when I get a chance

OK, I know this is an old thread - but I just got a replacement US996 phone; my old standby has a charger plug problem so I decided to get another one and put a rooted stock Oreo ROM on it. However, I'm having the same issue as the OP. Get into fastboot, flash TWRP (I have the 3.3.1-0 version, as the newer 3.3.1-1 version does not have any download mirrors). The flash appears to go just fine, it says the write was completed. However, when I reboot into adb mode and do "adb reboot recovery" I get "no command" and the little droid with his belly hatch open. So obviously TWRP wasn't flashed. The OP says he eventually was able to get it to work and install root. How did you fix the issue?

Do I still need to do the old recowvery shenanigans that we had to do back when the phone first came out?

Thanks!

I believe you MUST use the button combo to reboot into twrp.

I've done that. The problem is that TWRP hasn't actually been installed via fastboot flash recovery - it goes through the motions, SAYS it's been installed, but when I do the button combo, it actually does reset my phone rather than booting into TWRP.

Disregard the above. Flashed it again (4th time), and it finally took.

The same happened with my wife's US996 now that you mention it. Took a few tries and was a bit frustrating.

When I flashed TWRP on mine it was a "one and done".

Glad you got it sorted.

Thanks - all good. Rooted stock Oreo ROM installed, working great.
