What ROM to install for replacing an old ROM? - G2 Q&A, Help & Troubleshooting

I am currently running OptimusG3 V1.4.1 rooted, used TWRP, for over a year, and it's time to change. I have d802.
I need a new ROM that will be fast and clean. My main uses are surfing the net, whatsapp, music etc... nothing too demanding.
What ROM do you recommend?
Also I need a guide that tell me exactly what to do because I don't want a brick. I don't want to mess something because the modem version is not okay or something like that.
I want to make a clean install and remove all the things that are currently on the device. I want everything new and fresh on it.
If you need more details, please ask.
Thanks

if you have KK d802. this is how i do it .
you already have root and twrp right? i asumed as you have that rom on phone.
if not just search for root method for your variant/ and search for KK autorec for your variant.
then i would recommend updating your twrp, with blastagator thermal control twrp from here.
choose your variant. just flash thermal twrp to installe it.
http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
this is to take you to lollipop. am not sure if you want to stay in KK. if you do all you got to do is follow the roms installation instructions.. in rom thread. ... if you want to go lollipop then follow procedure.
back up al your data to pc.
go into thermal twrp. wipe all partitions including sd card. this will be a clean installation.
you can transfer files while you are in twrp too..
install this bootstacks for your variant. when install, reboot into recovery NOT TO SYSTEM. to take effect.

search for root method for your variant.... on playstore search for autorec lollipop for you variant install and flash twrp.
update with the thermal control twrp. wipe required partitions from post..
and flash rom... thats it. :fingers-crossed:

how can I go back to clean stock 4.4.2 KK, so that my device won't have TWRP, root or the ROM I have?
Do I need to update the baseband for that? or something else so that I won't have brick?
thanks

back to stock like from factory ithink you need to use TOT or KDZ method using flashtools.
follow the guide here . no when you do KDZ or TOT id deletes everything puts phone to zero state resets everything. no need to worry about baseband..

Yeah dont worry. Just follow the procudre described in the rom thread and you ll be fine. Just to prevent any prpblems you should back up your standard rom before start flashing

Help flashing a ROM on the d800

i have the d800, and i want to flash Blisspop v3.2 onto it. im currently on stock lollipop (d80030f). its been rooted, and i used autorec (https://play.google.com/store/apps/details?id=b007.autorecd800&hl=en) to get twrp, and thats all i done at this time. i understand that i need to flash the lollipop bootstack, but there are two files given on the thread, one for loki and one for bump. which do i need to flash?
Im pasting my reply from another thread please follow from where you left off at.
Ok flash back via tot to kitkat and take ota to lollipop. Then use autorec v2. *Do not use the twrp thats comes autorec as it does not flash roms* flash a BUMPED twrp using twrp. Then install your lolipop rom then afterwards install the dormainx d800 lollipop patch.

So i need to:
1. flash bumped twrp
2. install rom and gapps
3. install dormainx d800 patch
i think i get it now. since i already took the ota to d80030f, and then rooted i dont need to do the tot flash back to kitkat.
Yeah sorry about that I didn't feel like retyping my post so I copied it from another thread where a guys was stuck in bootloop.

Full method for installing CM12.1 on D802

Hi All,
I've been doing a lot of reading and would just like some clarification that I have understood everything correctly!
My scenario: I've bought a used (but in great condition) D802 from ebay UK, due to arrive soon.
Here are the list of steps that I think I should take to get it from stock LG android to the official CM12.1 (Lollipop) software:
1) Ensure that it is actually a D802 using this thread:
http://forum.xda-developers.com/lg-g2/general/refurbished-fake-lg-g2-check-available-t3069242
2) Assuming it's not on LG lollipop version, upgrade to LG lollipop using their official methods.
(This should give me the latest LP bootstack and bootloader)
3) Root using this method:
http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
4) Use AutoRec - Lollipop version from playstore:
https://play.google.com/store/apps/details?id=b007.autorec2&hl=en_GB
(This should leave me with LP bootstack, but downgrade the bootloader from LP to KK)
5) Go into the recovery (TWRP) which was installed by AutoRec and flash over a newer (also Bumped) TWRP recovery by blastagator
http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
(This recovery should be more recent than the one provided by AutoRec)
6) Make a full backup (including EFS partition) in blastagator's TWRP recovery
7) Flash official CM12.1 and OpenGapps
8) Smile!
If someone could check this out for me and give me any comments/feedback/advice, that would be most appreciated!
Thanks

flash hybrid bootstacks. go to main menu. reboot into recovery from recovery. then once in twrp flash rom gapps.

Thanks for your reply, raptorddd.
However, if I upgrade to the latest LG android software (LP), then use the AutoRec app for LP, wouldn't this effectively give me the latest hybrid bootstack?
Therefore, no need to flash a hybrid bootstack?
I'm sorry if I might be missing something here!

nope auto rec is twrp and it will give you old twrp so i suggest to use balsttagator thermal twrp.
you will have normal LP bootstacks most people get boot loop after flashing cm13. then installing hybrid boots phone.

Yep, I understand that AutoRec will give me TWRP (albeit an old version).
But AutoRec will also downgrade my bootloader to KitKat right?
What I'm asking is that if my phone is running LGs latest software update (lollipop), and then I use AutoRec, won't that mean that I'll then have a hybrid bootstack? (Evertything in the bootstack will be LP, apart from the bootloader which will be KK due to AutoRec's downgrade)??

if am correct theres only KK and JB bootloader. no LP bootloader so ithink you will have KK bootloader bumped.
and youll have normal bootstacks. there are bootstacks and hybrid. hybrid is recommended for stock,and CAF roms. most cm roms are CAF. so more compatibility.

Oh really? I'm sure I read that the latest available bootloader for LG G2 was a Lollipop one?
What I read may have been wrong, though!

Downgrade from marshmallow to lollipop

Hi,
I have a Samsung Galaxy sm-g900h phone which I updated to android 6.0.1 (Marshmallow). But after the update the phone's battery life decreased significantly.
Is it possible to downgrade it to the previous 5.0 version. Thanks
As far as I know you can I've done it so you should be good just put into download mode and flash with Odin
Could you please tell me or give me a link of the steps that I should follow?
Thanks

You have to first Install a Custom recovery like Philz Touch, Clean the rom, then flash in the old rom using Odin, or if you have it in .Zip format, its straight after cleaning the rom, go to install from SD card

Please stop providing members incorrect information. Philz is not a ROM it is a recovery. And if he wants to be on stock he needs the official firmware for his device and carrier from sammobile.com and Odin. He needs Philz or TWRP if he wants a custom ROM. However, I recommend a custom ROM over stock. More features and tweaks for the phone. You can also root and get kernel auditor and out it to battery save.
You should try clearing the cache partition and leaving the phone for a week to get used to Marshmallow. I'm on it and it's quite better than Lollipop, just give it some time to settle in
