Full method for installing CM12.1 on D802 - G2 Q&A, Help & Troubleshooting

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

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!

[Q] How to Upgrade to Lollipop from CM12 (Tmobile D801)

I have a D801 (Tmobile G2) and I’ve been running CM11 on it for over a year.
Now that we have lollipop, I want to upgrade to a ROM based on the official Lollipop release, (this one: http://forum.xda-developers.com/tmobile-g2/development/rom-tmo-lp-extreme-v1-0-4-16-15-t3084681)
Ofcourse I’m rooted and have a custom recovery installed, specifically ClockworkModv6.0.5.0/Philz Touch 6.48.4)
Can anyone please guide me on how to install the Lollipop ROM mentioned above. I’m thinking the first step would be to update my recovery to a TWRP recovery…. How do I do that?

And then I just flash the Lollipop based rom? Even though I'm on CM11 (kitkat)?

That depends, you might need the latest bootstack for the new CAF-based roms, but not everyone seems to agree. I would flash it anyway though, this would prevent any issues like sound bugs and anything else you might find.

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.

so the D802 BUMPed zip is also JB bootloader,right? I compared the aboot.bin of the bump one with the loki one, it's the same MD5. Could you please replace the JB bootloader in bump zip to KK bootloader? Because if we need JB bootloader we will flash the loki zip instead of the bump one,but if we need KK bootloader we have nothing to flash.

Hello, I'm running cm12.0 on ls980 . came from stock kk , used autorec , recovery is now 2.8.6.1. So I assume I need to flash the kk bootstack. If that's correct, do I flash bootstack first then cm12.1? Do I need to wipe cache after flashing bootstack and before flashing 12.1. Or do I not wipe cache at all? And do I need a different gapps then what I've been using for 12.0? So sorry for being a pain. Thanks in advance

I'm running AICP 5.1.1 on my LS980. The only thing other than the ROM and gapps that I ever had to flash was a modem. What is a bootstack? Would it improve my experience? If so, which one should I flash?
wich one i have or how doi check. i had lollipop 5.0.2 d800 30c i think..now on cloudy 3.3
not sure what to do
ok so let me start off with that i am sorry if this answer can be found on another forum or has been already answered, i have been looking for hours and have not found an answer. so the question is what happens if the bootstack fails to flash what steps can i take to fix this? and if my LG G2 doesn't boot after flashing this would there be a way to fix that? btw i wouldn't like to have to get a jtag repair if i mess this up. thanks in advance!
Hi guys.. I have a question. I am on cloudy g2 3.3 and i want to try CM 13.. I have done a full backup or the rom. If, after the flash of CM, I would go back to cloudy, have I to flash some bootstack or bootloader?
Inviato dal mio LG-D802 utilizzando Tapatalk
Dear Helper,
This question might not belong here, but I'm looking for an experienced response.
I was on cloudyG2 2.2 KK on LG G2 D800 (AT&T). Updated bootloader to "bootstack-d800-KK_20y-v1.1-blastagator-signed.zip" via TWRP 2.8.7.1 and then flashed CloudyG2 3.3 LP. Now facing a problem which is;
When I reboot the phone from within the OS or turn it on from an off state, it goes into a bootloop on LG logo, every time. I then have to enter TWRP via hardware button combo and reboot system from within TWRP and only then the phone boots into OS. Besides the bootloop, the phone is working perfectly on Cloudy once in the OS.
Where did I go wrong? Did I flash something that I shouldn't have? Did I break something? Any way I can fix it?
Any help will be appreciated.

What ROM to install for replacing an old ROM?

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.

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..
