From Lollipop to Kitkat (Rollback) - G2 Q&A, Help & Troubleshooting

Can some one tell me what do I need to Rollback from Lollipop to Kitkat ?
Is it imposible to do that with TWRP ? LG G2 D802 Blisspop v3.3

Yes, there are other ways, like installing different zips to return the partition table, boot, recovery, but is more risky.
Why are you afraid the simplest and surest?
kdz install is the safest way.

Hi. First of all, sorry for my english.
I've got a problem when I try to install custom recovery or TWRP or Philz.
This is what happens when I install it in my LG G2 D802.
/dev/block/platform/msm_sdcc.1/by-name/aboot: cannot open for read: Permission denied
Unable to open /data/local/tmp/aboout.img: No such file or directory
[+] loki_patch v2.1
[-] Failed to open /data/local/tmp/aboot.img for reading.
[+] loki_flash v2.0
[-] Failed to open aboot for reading.
Reboot into recovery no [y/n]?
I tried everything and it still not works, i'm going crazy :laugh:
I hope that you can help me. Sorry for my english again, thank you all.

Yes, it's rooted. And it's 4.4.2 stock rom.
I've tried that but the app says: "AutoRec cannot install it. Try to install it manually" or something like that.

Autorec doesn't work on every variant. You might have to flash a different stock ROM using this http://forum.xda-developers.com/showthread.php?t=2432476 and then use autorec. What is your software version?

His error actually said that Autorec couldn't install loki(it means : 1. it isn't properly rooted 2. it isn't stock rom 3. he didn't give the permissions)

I think i've done it all. My rom is this:
6H3/HUTCHISON_16G(UNITED KINGDOM) V20D LGD802 from LG firmware lists (I can't paste links)
I'm from Spain and that ROM is from United Kingdom, could it be the problem?

OMG. I don't know how I've done this but AutoRec has finally installed TWRP. And I can enter recovery mode and it appears Team Win.
I've rooted it again and installed the apk. Thank you guys.
Can I install custom ROMs now, right?

Are you sure, AutoRec has granted ROOT permission?
Look for this in SuperSu app.

not sure but maybe skr tools might help, or what about flashify.? not sure if flashify can be used though.
Im running the exact same make & model (G2 VS9803AA). Were you able to find a safe & reliable method of installing TWRP, by chance?

Flash VS98039a firmware using KDZ method. Then root the phone using LG Root Tool. Install AutoRec Lollipop from Playstore to install TWRP.

KitKat Roms won't flash?

Hey everyone little confused here, im looking to install a kitkat rom on my VS980 , yes yes i know why would i wanna go 2 android versions back? Just my cup of tea i guess. Anyways whenever i try to flash kitkat roms such as CM11,SlimKat,LiquidSmooth, etc it fails to install? Ive used bootloader changer and tried all of the bootloaders to no avail. Im on kitkat bootloader as we speak and i have paranoid android lollipop on it, since thats all i could get to work. If you need more info , i shall provide it.

You said Official rom so I am guessing you mean Stock No root. The H910 does not have a KDZ file to flash so you have to flash the twrp files. They are safe.
This one will bring you back to Nougat 10q Stock No root.

This one will bring you back to Oreo 20g Stock No Root.

Thankyou. I am guessing I can't use these with download mode then and will have to get TWRP on the phone first.
