How do I upgrade FW when rooted? - G4 Q&A, Help & Troubleshooting

Hey peeps!
So, I have a rooted a rooted v10h fw H815L.
Since I've rooted (about mid Oct) there have been 2 fw updates from my Israeli carrier (v10i and a very new v10k) which seem to fix some issues.
Now I want to update the phone, tried via LG Bridge but the update seems to fail.
What's the easiest way for me to update it now?
I don't have the patience for backing everything up and then restoring, and I don't mind updating to a non-rooted version and then root it back later on.
Thanks!

Did you try flashing a KdZ file? Also there is a rooted image in iandroid forum

[Q] 4.3 10.4.B.0.569 OTA upgrade fail when rooted

Hi,
I have ZL 6506 with stock generic US 10.3.1.A.2.67 rooted using Root_with_Restore_by_Bin4ry_v33 option 0.
I tried upgrade to 10.4.B.0.569 OTA but it failed. When I don't root, the upgrade is successful.
Is anyone else having the same problem? Is there someone have upgrade to 10.4.B.0.569 OTA and kept root?
Thanks
Yes I couldn't OTA either.. didn't know why.
I guess it might be that.

it differs from phone to phone n firmware to firmware are you talking about 6502/3 with 4.3?bcoz i couldnt update rooted xperia m either
OTA upgrade worked on previous versions like .244 and .67. I kept root when upgrading via OTA but no luck on thi .569 4.3.
Ok so it wasn't just me..
Yep I used OTA every update since 1st firmware. Retained root everytime.

I've also been doing an OTA up until now, but this update just appeared two days ago and I can't get it to apply. in the past I would just relock the bootloader and the OTA worked. Doesn't seem to this time.
Has anyone been able to install .569 via OTA from a rooted device? And did you retain root?
If so, did you do anything special to make it work?
Note I'm asking OTA, not flash.

Question on Updating FW onced Rooted

Hello
I have a Tab 10.1 Wifi that I rooted with Odin. I want to update to the newest FW, and I downloaded it on Sammobile. I know I have to use Odin to update it, but will I lose root?
If I do lose root, do I use the same method to re-root?
Also, now that I am rooted, what would happen it I tried to update the FW with Kies?
Thanks for the info
Jason

Some answers : yes, you will lose root when you use Odin. Yes, you can use the same method to re-root. I don't use Kies, so I don't know the answer there.

Using Kies was the only way I was able to update the firmware to the previous large update (the one prior to the Kids Mode update). I couldn't update using OTA, as I was getting the "Your device has changed. No updates available." message. So I read somewhere to try updating with Kies.
Once I updated using Kies, the update was successful, but I did lose root access as expected. I'm pretty sure I can root it again, as I haven't seen any posts to the contrary, but I haven't rooted it yet.
Thanks for the replies!
Does Towel Root, the 1 click root work?
Is there a way to save your root, update and re-apply root?
Thanks
I have. 10.1 wifi. Recently updated using Kies. Lost root, and was able to root again using the same root method I previously used. I tried towelroot, but could not get it to work.
NOTE: I and several others have reported random reboots since this upgrade (that added kid mode). I am on the US.

flashing lollipop update

i need help here. here's my scenario. im using lg g3 d855 with kitkat 4.4.2. i got an OTA notification update to lollipop (v20b SEA), since im rooted i tried to flash this using the lg flash tool with the correct kdz file. i was able to update it to lollipop and everything seems fine; however since i find it pretty big(for dpi) and also not rootable yet, i tried to downgrade again to kitkat (v10k) and it went fine. i was able to root it using purpledrake l, then install twrp to revert back to my nandroid backup. so overall, everything went back to normal.
after 3 days, i decided to go thru to lollipop again
so i did the flashing of the update, but after all of this and during the initial setup, i noticed that mobile network isnt working. i tried to ignore this and just continue to finish the setup. after all is done, and im on the homescreen. i noticed that i dont have the navigation button. also when i tried to switch on the mobile network, it was grayed out. i tried all the possible method of reflashing back this lollipop updte(even redownloading a fresh copy of the kdz file), but to no avail.
question is how to flash back this lollipop update with all functions working?
any help will be much appreciated. sorry for the long story!

Is it possible to do OTA update for my rooted v10B?
If not, Is it safe to do the upgrade via LC Bridge? Does it wipe my data?

AT&T GPad F 8.0 (V495) Marshmallow 6 OTA Upgrade Fail

Hi my friends, I am looking for a STOCK RECOVERY for my LG G Pad F 8.0 AT&T (V495). I was trying to do an OTA upgrade to 6 but after the Download and restart the installation is giving me an error because i am ROOTED. I need to flash stock recovery to be able to install new OTA upgrade to Marshmallow 6. Is someone have a 5.0.2 STOCK Recovery or maybe another idea on how can I do and upgrade to Marshmallow 6 I will appreciate any help. Thanks
Is there a KDZ or TOT available for your variant?
I am in the same boat. I can not find the stock rom anywhere. I would like to upgrade to to 6.0. I am rooted with king root. If the stock rom is not found is there a way to unroot and delete all root files so the update does not detect the root so we can update?

In order to take OTAs (starting with Lollipop) you have to never have been rooted (since the most recent time you've flashed a KDZ or TOT).
Unrooting isn't enough.
