[Solved] H990DS only able to boot into fastboot and static screen

[Higgings]

Hi,
I was trying to install Super Rom but unfortunately I am unable to boot the phone. I had rooted the phone a while back. When I try to turn the phone on I get stuck with the dreaded static screen which is normally an easy fix however I can't boot into TWRP as that gives my a static screen too. The only thing I have access to is the fastboot menu and when I try "fastboot reboot" I get stuck at the LG "lifes good" screen. I have tried to flash two different versions of TWRP (one given in dirty santa and the most up to date for H990DS).
Any ideas will be greatly appreciated!

Don't use fastboot reboot. That starts it booting the stock rom, which before the first boot into twrp reflashes the stock recovery again. You need to pull the battery to leave fastboot, then boot into recovery by holding volume down, holding power until the screen turns on, then tapping power repeatedly until it asks to factory reset, say yes. When twrp boots swipe to allow writing to system and flash something. Then booting the rom won't eat twrp anymore.

Thanks for your help, but I have managed to fix my issues! I will add in a fix guide later for anyone else that stumbles upon this.

So I can now boot into SuperRom but I am unable to go back into TWRP. When I do the usual button procedure to get to TWRP I am asked to do the LG reset thing, I press yes twice and then I am met with this screen:

To boot into Android I need to open fastboot and reflash the recovery, then reboot but I still don't have any access to the recovery. Any ideas?

Flash my twrp instead.

Flash my twrp instead.

I'm fairly certain that's the one I'm using, but ill re-download it and try again.

Just downloaded your version and it was indeed the one I have been using already. I did however download it again and tried to reflash it using the method you stated above but I end up with the same screen. The only way I can get it to boot into Android after that screen is to boot into fastboot, flash your recovery then "fastboot reboot".

Problem solved! Solution:
1. Download the TWRP app from the play store
2. Using the app, flash Phoenix591's TWRP (here)
3. Use ADB and reboot into recovery using "adb reboot recovery"
Once I did these steps I was able to use the usual method (volume down, release power for one second etc) to boot into TWRP. Happy days!
