How to upgrade! - G2 Q&A, Help & Troubleshooting

So the last 2 times I have updated ota I have gone into a bootloop. I tried complete wipe then flashing kk modem then pa and pa gapps to only be stuck in another boot loop! At this point I'd just like to be able to get a 4.4 rom. How do I do it without bootlooping? Thanks!
Here's my software info!

Download a 4.4 ROM from here, copy it to your phone, then flash it in recovery.

I do that and I get boot loops no matter what I try. Eiither that or it will only boot to recovery

@hdjx20 You need the KK modem as well. Wipe, then flash modem before or after rom/gapps.

Getting a rom to flash

I finally got twrp to install on att after ota. The version is 2.6.3.0. I did it with the freegee app. I made a back up of my stock rom. I tried to flash Aeon rom but it will not boot. I flashed it twice like it says in the thread. I saw were some people were having issues getting it to boot. I cant get recovery to update to the newest version. I tried using flashify and also flashing in recovery. Will i be able to flash a rom on 2.6.3.0.

I can't upgrade twrp either. I think mine has something to do with my.OTA and root after. Tonight, after I find all the required files, I'm going to flash back to stock, pre-OTA and try again.

Would assume it's your recovery. You can't flash 2.6.3.3?

I've tried every which way to flash it. I have 2.3.6.0 from freegee. For whatever reason, I can't upgrade to anything other.

Every which way? There's really only one way lol.
Negative. Via freegee, flashify, from the pc, via twrp, that's more than one. I can't get it.to update twrp past 2.3.6.0....... I've been thru all the different options......

You said you couldn't get Intl recovery to update twrp. Download 2.6.3.3, go into recovery and flash that zip. It will update your twrp and you'll have no issues flashing 4.4 ROMs.
I don't suggest using 2.6.3.4 because people have reported issues with it.

If you can't just flash the 2.6.3.3 zip, then I have no idea what to suggest. I installed twrp by pushing it from my computer and was able to update with no issues. You will not be able to flash 4.4 ROMs with anything less than 2.6.3.3

Ah, I must have missed the bit about you taking the OTA. I was wondering if after taking it, whether there was a root/recovery method.

Use 4.4.2 Stock Recovery to Flash Zips

Hi,
Is it possible to use the stock recovery to Flash zips? Alternatively will using the app Flashify to Flash the zips cause any issues? This is for a D802 on 4.4.2.
Thanks

From what I remember, the stock recovery doesn't have that function.

Ditto
Stock only flashes signed zips. Like official ota and such.
Flashify to flash, well all depends what it is. U can flash recoveries safely but not stuff that is in operation. Some, maybe like sound mods that require reboot.

Can I flash a non stock kit Kat Rom

I have the flashable through recovery version of stock kit Kat. Since I did not use a LG tool to flash it, can I still flash another non stock kit Kat Rom or do I have to downgrade. I still have twrp so I'm guessing I should Be ok, just worried about partitions.

Do you have custom recovery? Then yes. Are you referring to ROM's like CloudyFlex, etc?
Ya twrp, went to install Mahdi Rom for d801 and got horrible reception and no data, so was curious if it's a kitkat doing it.

You flashed this radio right? http://forum.xda-developers.com/showthread.php?t=2705509
Also, if you wish to use stock KK ROM's just wipe and flash away.
Yeah I flashed that and than tried a T-Mobile only modem, no auto rotate either so that might be the problem

[Q] Stock recovery missing!!!

I have an AT&T Samsung Galaxy S4 SGH-I337 rooted. I tried to flash a custom recovery with Rom Manager, Rom installer, Safestrap and Odin in that order. All my attempts failed because the boot loader is locked and now the stock recovery its gone. My question is: If I flash a stock ROM like out of the box (NB1 OTA) in ODIN that return my phone back to original settings and with the stock recovery too? Thanks in advance!!!
Yes, your only Odin right now is to flash the full Odin tar file

No you can't go backwards with bootloaders. I assume since you weren't able to do custom recovery you're on a newer firmware nc1? If so you can root with towel root then only use safestrap as a means for recovery. But you'll only be able to install touchwiz based roms.

Use this http://forum.xda-developers.com/lg-g2/general/d802-bootloader-changer-1-1-jb-kk-lp-t3104380
And then flash a KitKat baseband then you can install KitKat Roms.

Possibly, download twrp from blastgator it is bumped and doesn't need loki signature.

If you really want to go on a KitKat ROM you will have to use the tot method to get to stock KitKat and then root your phone using stumproot/towelroot. Then use autorec for KitKat to install recovery then update recovery with blastgator twrp then install KitKat baseband then you can flash your KitKat ROM. Make sure to do wipe before installing new rom

In all honesty, if the method I have provided has not worked then flash back to stock KitKat and follow the guide I typed above.
