[Q] How to Upgrade to Lollipop from CM12 (Tmobile D801) - G2 Q&A, Help & Troubleshooting

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?

Flash the TWRP.zip inside the CWM recovery,then reboot the recovery.

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.

Root after manual update?

So I finally found some time for my unlocked and rooted nexus 4. Right now it is on 4.3 stock and I want to update to 4.4.2. Now the question which I couldn't find an answer on Google: Do I loose root after manual update? I've seen some videos on that, but some say that you need stock recovery (I have TWRP), but nothing about root.
Also, I'd install Franco kernel after that.
Help and possible tutorial would be appreciated, I'm still kinda new to android.
You can have a stock experience by installing the Experience ROM in the development thread.
Make sure you are running the latest TWRP before trying to flash a 4.4 ROM.

Yes, always when you flash another stock Rom, you will lose root.
But it's a matter of seconds to reroot after flashing latest supersu.zip through TWRP.

[Q] Flashing Kit Kat Based Custom ROM

Hi ,
I just got my G2 Yesterday , rooted and flash TWRP right away on the stock 4.2.2 . I am tempted to try out some Kit Kat based custom roms now. I have a few questions
1-) Can i directly flash KK based custom rom ( after a full wipe of 4.2.2 ) ?
2-) Would i be able to go back to my stock rom via nandroid after KK custom rom ? i.e going into recover and flashing the backup again ? ( heard there are not custom recoveries for KK ? )

1-) Yes, kinda. Just look for instructions in OP of the roms. This one works pretty well: http://forum.xda-developers.com/showthread.php?t=2667714 (Only D802 there are LG KK Roms for other variants though, just search the forums)
2-) No, there's no custom recovery for 4.4.2 yet, but devs are getting close. Read more about that here: http://forum.xda-developers.com/showthread.php?t=2667227
Edit: One more thing: You can of course flash AOSP 4.4.2 roms and will keep custom recovery.

So if i understand correctly. There would be no going back from a KK based rom except using the LG tool to flash the stock KDZ right ?

Only AOSP? I just got this phone and I'm familiar with adb and the rooting/recovery process but does this mean I could install a 4.4.2 version of cyanogen or paranoid android or BeanStalk over 4.2.2 and keep my custom recovery?
sent from my potato
This depends on your variant. The D800 kitkat has been moded to allow a mixed match of partitions that allows the previous loki enabled recovery to run. This was released yesterday But Is only possible thanks to the release of the kernel source for the D800 from LG. Other variants will follow. In fact the D800 versions from AndroidUser0011001 and garyd9 will flash from your custom recovery, no LG Flashtool required

Thanks guys !
I think its better to stick with stock rooted for now and jump to KK when all the necessary stuff is made available. So that jumping between KK and JB is easy .

[Q] CM11 Problem.. Help Needed

Hi all,
I am interested in the CM11 ROM. Last night I spent 6hrs trying and failed, epically.
Here is what I did already:
1. Downgraded from 4.4.2 back to factory
2. Successfully rooted
3. Installed ROM Manager
4. Successfully downloaded CM11 and latest GApps
Then when I tried to boot into recovery it kept going to a screen with a little android guy lying on his back with a red triangle!!! I tried six times.
I got frustrated and just updated back to 4.4.2 and have been dealing with it. I am still rooted and have been able to remove my bloatware and other things you need root access for.
Any thoughts or help as to how I can install the CM11 rom?? I am happy running NovaLauncher and using DynamicNotifications to approximate it but really want to try out CM11.
Cheers and thanks!
Lucky there is no way to root on 4.4.2 yet or atleast no Recovery's yet it could be worse you're atleast rooted and it didn't brick your phone

Did you actually try flashing a recovery first? Just installing ROM manager won't install the custom recovery needed to flash ROMs. You have to do that step as well.

No, I didn't. I am super new with android. Had an iphone for a long time. How do I flash a recover? Can I still do it now on 4.4.2 b/c its rooted?
Sorry about the noob questions, everyone is being very helpful!

LG blocked the Loki exploit with 4.4.2 so you can't flash recoveries currently. You'd have to flash back to 4.2.2 to do that. Which if you want custom ROMs now its going to have to be done sooner or later. Which carrier and model number do you have? If you have an international D802 the above post by @zekurosu will work for you, otherwise don't use that one. You're gonna have to find the method for your model number.
My first guess was that you missed the flashing the custom recovery step, which people above me have already helped ya out on. For being new to Android you did fairly well, you just missed that one step.
Good luck!

I have an ATT D800 running 4.4.2. I can't decide whether its worth it to flash back to 4.2.2 to try again. Pretty happy with NovaLauncher + widgetlocke and fairly closely approximates what I am looking for.
For what its worth, I was in 4.2.2 when I tried the first time and failed. I think mackster is right, I didn't flash the custom recovery. I basically flashed back to 4.2.2->rooted->tried to boot into recovery (OVER and OVER) then gave up and upgraded back to 4.4.2.
Thanks for all the help. At least I now have a rooted phone and have been able to do some cool stuff with that. My goal is to get nexus 5 software in an LG G2 body (battery, camera, etc)
@android_nashville There's a way to have the best of both worlds. You can flash back to 4.2.2 (10d preferably) root, flash a custom recovery with Flashify or FreeGee. Both available on the play store. Then actually update to 4.4.2 following this thread http://forum.xda-developers.com/showthread.php?t=2483043. Eventually, if you want to flash custom ROMs you're going to have flash back to 4.2.2 and do this process regardless. The 4.4 aboot image (bootloader) can't be bypassed with Loki. Its been blocked. But some brilliant devs basically found out they can make a hybrid setup, with the 4.2.2 aboot, and everything else 4.4.2. This way you can have the ability to flash custom recovery, kernels and ROMs.

[Q] Help Flashing on Sprint G2

So I'm on 4.2.2, rooted.
I just flashed CM11 (first with, then without gapps) and got an annoying bootloop; just the LG Logo.
Luckily I had a backup of stock, so it's all good.
The thing is, I really want CM11.
So what are my prerequisites? Do I have to flash a certain radio or something? I did everything right in every one of my attempts (Flash system, data, cache, etc)
Any advice?
Thanks!
---------------------------
Just flashed TWRP that apparently has the Loki hack (.zip file via Flashify) and same result.

Glad I'm not the only one with this issue, I gave up on trying to install cyanogenmod after numerous failures, I believe it has something to do with having the ZV8 version of The Sprint G2, luckily there's a ROM out there based on cyanogenmod that will work with all Variants of the LG G2, I think your will enjoy this ROM.

If I had to guess I'd say you're on ZVA. Try flashing the ZV8 modem, then CM and see if that works. Get the most updated twrp and CM11 also. CM just released the M8 version yesterday which is a snapshot or stable build.
I had CM up and running a couple weekends ago. Started from ZVC so I had to flash the ZV8 modem for it to boot. Smooth running after that.

Well it took me forever on my friend's wifi to download CM and Gapps, so I think I'm just gonna flash the modem like the other person said and get CM11 working. I'll try your method when I get home and have faster download speed. Lol.
Thanks though!

:good:Excellent, glad to hear that worked for you. LG is definitely more difficult to work with than some other brands. My last device was an HTC and it was so easy to flash roms back and forth. \
Go ahead and grab the modem zip for ZVA (if that's what you were on) to have in case you want to restore your backup. Flash that, then restore. Otherwise it will bootloop also.

Welcome to the G2! Take a look at the stock camera mod by xdabebb in the G2 development section. Well worth the time. G2 Tweaksbox is another favorite. It (along with the xposed framework) allows you to customize tons of areas if the LG skin.

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

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.
