L Update

I'm sure I overlooked something but I'll ask anyway. Is it possible to update without losing root and having to reinstall modified TWRP 2.7.01?
Sent from my Nexus 6

Anyone have a flashable TWRP for it yet? That would be NICE

I have managed to root the device but TWRP is not working on aboot 5.0.2. You can see the post links below.
It is merely few commands on 5.0.2 to run recovery by downgrading your aboot to 4.2.2 but then, Lollipop wouldn't start and you will need to reflash aboot 5.0.2.
So basically it is a choice between Lollipop rooted without recovery or Kitkat with root & recovery. I think we are not flashing anything as yet so it would not be much of a problem actually to not have a recovery. When we do need however, we can downgrade our aboot and flash twrp using loki and then flash the rom we want to.
Look into my guides for more details

Yeah I recall rooting it first time. Pain. All the Loki this Loki that.. Asking bc I upgraded my KLTEVZW by way of a flashable zip (4.4.4-5.0). Thought it may be possible on G Pad?

How about you root and make a twrp backup. Win, win

Check my ROM in my signature below, just flash the new official VK810 altev LG G Pad 8.3 35A_08 5.0.2 ROM from TWRP.
Also, questions should go in Q&A, not in General.

Have you tried CWM? Rumor is there's a new TWRP that hasn't been released yet, for what ever reason.

No twrp to flash, yet?

It's not a rumour. It definitely exists. It won't matter what recovery you use or what version as to whether you need to swap aboot.img versions temporarily if you're running stock LG Lollipop, if that's what you're wondering. 4.2.2 aboot.img lets the custom recovery boot, anything newer doesn't. And stock LG Lollipop won't boot on the 4.2.2 aboot.img, so you have to swap the new 35A_08 5.0.2 aboot.img in to get the ROM to boot.
I'm guessing the dev who made the newest TWRP for the VK810.4G is waiting to release it to the public until/if he gets CM 12.1 completely straightened out for our device. He'll probably release both at the same time.

I'm not sure what you're asking here. 2.7.0.1, 2.7.0.2 and 2.7.1.0 are all publicly available for us.

Idk. Some guy was bragging about using 2.8.6 saying it "wasn't publicly available yet" not to long ago. Only reason I said rumor was I had no proof.

Honestly I could care less what version he has. BL still locked. No mr , just felt he was name dropping or bragging. " I got it and you don't " sorry

Easy steps

I'm new to the g2 tinkering scene....
I have rooted my d802, installed and ran autorec and updated TWRP. And my Android version is 4.4.2
I want to change the rom, however on this phone everything seems so difficult....with having to change bootloaders and radios etc etc
What's the easiest way for me to begin? Is there a rom that I can flash with ease without having to mess about too much until I have learnt a little more

Bump anyone?

Nope not really. The easiest thing to do first is download the bootloaders and the modems. I suggest for you to download nevax bootloader changer and just google lg g2 d802 modems.
Just read every OP carefully while flashing and you will be fine. You can't flash roms in the lollipop bootloader so you have to first downgrade with autorec d802.
First root with lgroot it should work.
Downgradecusing autorec then you should also be able to enter twrp. Enter twrp using the recovery combination for jellybean. So with power+ volume down. ( small note, jellybean and kitkat have different recovery mode key comhinations butnthe kitkat20h should have the same as jb I believe.)
Once you entered recovery and downloaded the right bootloader, bootstack, modem then you will be able to flash the roms ya want. Ofcourse all for d802.
Some additional information
Download all the things for the d802, another model can cause so soft or even hardbricks so do it carefully.
Download autorec for d802 as the wrong version could cause an hardbrick.
Read every OP good and everything from what you are downloading. It will be hard from the beginning but after a while you can just do it like chewing gum.
If you are flashing a rom and it says that it fails and something about loki then you need jellybean bootloader.
Bump roms are all for kitkat bootloader.
Most of the newer roms are all using kitkat bootloader so I suggest to stick with the new roms so you don't have to change everything.
Watchout with the weird named vietnamese stock roms as some of them may contain bootloaderstack (additional files next to the bootloader itself) which could cause other rome not to work properly after yu flashed it so you will have to use autorec, some revert zip or some bootloaderstack zip for the d802.
Lonf stort but I hope this is all the information you need.

Well that's a fair bit to take in, I will read everything you wrote a few times over before I do anything.
I was looking at a rom, it doesn't say anything about bootloaders etc....and its 4.4.2, so can I not flash this without changing anything?

Its an old rom so it's based on jellybean sourcecode so I suppose that you need jellybean bootloader and bootstack. And probably lg g2 d802 kitkat aosp modem.

Need Help Flashing Custom ROMS

Hi guys,
I'm a newbie in this rooting world. So please bear with me. I know this forum will help me solve my problems and answer my questions so here goes.
The problem is I can't flash any rom. I'm having this error
"E:Error executing updater binary in zip '/sdcard/Download/CM12/CM-12-20150802-NIGHTLY-D802.zip"
What I did was
-Rooted my phone
-Install AutoRec to install TWRP Recovery
-Install quickboot
-Reboot into recovery
_Update my TWRP recovery to 2.8.7.1 bumped
-Backed up my everything
-Wipe everything (except Internal Storage)
-Install CM12 alongside with GAPPS
Now everytime I flash a rom I end up with that error.
My device is
LG G2 D802 Rooted Running on 5.0.2 Stock ROM.
Can somebody help me please? It will be much appreciated.
Thanks XDA Members.
Can you also suggest some good ROMS compatible with my device?
Thank you.

I got exactly the same message on my d802.
Unfortunately, I wiped my system and it rebooted with a "security error" message. I had to restore a stock LP ROM using LG's Mobile Support Tool program.

@audit13 and @markl098 official cm12 might be still using the old loki method of installing so it will need the jellybean bootloader. Most of the times if you get that error you are using a rom which is using loki on a kitkat bootloader. I suggest to use nevax bootloader changer and flash the rom. You might also need another modem for it. Search it on the forum which modem you need for the official cm12, you probably need kitkat aosp modem from dr87.
I also suggest to look for the newer roms in the forum here in xda as most of them are all using new caf sourcecode and running on lollipop bootstack with bump. (Ofcourse kitkat bootloader)
Audit13 the security error probably happend because you wiped the system but the boot.img remained and loki isn't signing the boot.img with an lg key so it will result on kitkat bootloader in an security error. With bump that problem is fixed as the kernels are getting signed with an lg key. I hope you guys can flash now happy further with no probs

Thank you so much for your answer. I can't find much info on that regard. Things becoming more clear now. Can I ask one more question?
I was on stock, decide to try SlimSaber, which is quite nice by the way. So, I rooted my D800 and got TWRP. Then flashed Loki's lollipop bootstack (bootstack-d800-LP_30d-loki-signed.zip) recommended by OP and ROM and GAPPS. Everything works perfect. Now if I want go for 4.4.2 based stock ROM for example I should flash K.K bootstack before? I found this file - bootstack-d800-KK_20y-v1.1-blastagator-signed.zip. So is this mandatory always flash bootstack before upgrading downgrading, right? I can't find any detailed info on this in XDA unfortunately.
Thank you for your time.
Greetings.

Ehhm. You can try it. The reason why is because the use of bootstacks became more since lollipop. You can try it. Perhaps it works else you could always autorec and then folllow the guide on how to flash. I can test it perhaps also for you later. Ofc with my d802 version but I am still underway from heading back so I can test jt only from wednesday
@audit13 no problem. :good: enjoy

@audit13
Can you tell me how did you do it ? I'm really new to this.
Edit:
NVM, I figured it out. I just used the nevax's bootloader changer. Changed to JB Bootloader and now I can flash custom roms with no errors. Thank you @wulsic

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.

Loki or bump?

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.

Is 5.0.1 better then 4.4.4?

Hello,
My I9505 is now on Omega 4.4.2. Now I would like to update my phome to a 5.0.1, because I see on sammobile the Original one is out.
When I read on the internet I see some sites where they say it's better to stay on 4.4.4 then go to 5.0.1.
They say 4.4.4 is more stable then 5.0.1 and 5.0.1 miss some important features.
Who can help me with this. Is it good to update to 5.0.1 or is it better to go to 4.4.4?

Tbh,this Question isn`t easy to answer because its subjective. There are changes (some for the better,some for the worse) and you have to "re-learn" some things regarding Android in general but overall it all depends on you (if you like these changed/can handle them). I may be wrong but the performance is about the same so that shouldn`t be the reason to update

Well oke thanks for the answer. Of I go to 5.0.1, can I go back to 4.4.4? If yes, how? Only flash a 4.4.4 rom or do it with odin?

No, it's not good to stay on an outdated firmware. You leave your device vulnerable to malware etc. It's even better to flash Cyanogenmod and be on the latest version 5.1.1.

Thanks! But 5.1.1 is not out for the I9505 I see on sammobile. Will it be fast and stable enough?
And CM, why that and not the android version self? Why is better to use that? I never installed it before.

No, it's not out and probably never will.
There are lot's of roms that are AOSP in the development section. You have to Google for yourself what all the differences are.
Bottom line: If you want to keep running a version that is outdated and more vulnerable to malware then keep using 4.4.4. If you want your device to be up to date then flash a CM/AOSP based rom. And yes they are really stable.

I will search and look what I will do. 1 more question. Once on 5.0.1, I can;t go back to 4.4.4 or lower, is that true?

imo its better...

No, not true.
You can either go back on a custom rom or on stock. But on stock you need to keep using the Lollipop modem.

Will install today a 501 rom. Thanks all
