Hello all!
I just got the push for the 4.4 upgrade on my phone but I wanted clear a few things up before I commit. I'm currently on a rooted 4.3 with a modded radio for LTE. Is it safe to just run the OTA update from my phone? Or is there another proper way to prevent bricking? How should I go about this?
Thanks guys!
There are a lot of variables such as programs and versions installed, but I tried the OTA under similar conditions as you (In my case I was rooted, hybrid 27/84 radio, unlocked bootloader, TWRP, Koush's superuser, and otherwise stock 4.3) and it just didn't work. I even reverted back to the old radio before I tried it, but it might be the modified build prop or LTE activation that caused the problem. The OTA did not brick my phone or cause any other problems, it just didn't change anything on my 4.3 install. I could see while the update was running that it failed right after examining my existing install, so it didn't like something with my existing system config. I then did the following from the advice on this forum and my upgrade to 4.4 went flawlessly (Post #13):

I just flashed the entire image of the os on top and didn't lose data. On twtp, LTE back, unlock boot loader from 4.3.

I have a recently rooted N10 on Android 4.4 build KRT16S. I have had the system update to 4.4.2 in my notifications for weeks now. What I wanted to know has anyone installed this update without any problems? and am I likely to lose root? Bit clueless as to how these updates work but saying that I did manage unlock the boot loader and flash my tablet without any issues. Also if I shouldn't install the update how do remove this update. Thanks in advance folks, Phil.
The update may or may not work, it depends on how much you've touched the system files. If you've just rooted it, the update should work. If not, you can flash the factory image (except for the data partition).
You'll probably lose root, but on a unlocked bootloader, that's nothing to worry about, as you can trivially re-root it.

Hey all,
Having a small issue with my Verizon LG G2.
When I first got it on launch, I rooted it, installed loki (to bypass the locked boot loader) and have been running custom ROMs.
This is the way I ahve been running it since, on 12B, with loki and CM11.
Before I installed custom roms I did a image backup using Clockwork.
Yesterday I bought a Droid Turbo, so it was time to restore the G2 in preparation for sale.
I attempted to restore my original backup of the stock image, but it failed (stating something about an inability to restore/system, resulting in a soft bricked phone.
I fixed this by downloading the LG Flash tool, and the stock 24A .kdz image, putting the phone in download mode and flashing it.
The LG flash tool seemed a bit buggy, complaining about not finding servers, but eventually flashed the phone with the .kdz.
Everything seems to have worked well. Root is gone, clockwork is gone, (and I assume loki is gone as well, but I can't tell) but now I can not do the latest OTA updates, and am stuck on 24A.
It's not that it downloads the OTA, and then fails to install it, but rather it complains that it is unable to download the updates at all.
I was thinking this might have something to do with the fact that the CDMA radio is now unactivated (since I got a new phone) and it somehow needs to verify with the Verizon network prior to downloading, so I grabbed a working SIM and popped it it in. Even with 4G via the SIM, the OTA downloads don't succeed.
Does the CDMA radio need to be activated in order for a phone to receive OTA updates? If not, I ahve something else wrong going on, and would appreciate any suggestions regarding fixing it.
The plan was to sell the LG G2 to pay for my Droid Turbo upgrade, but I don't want to sell the phone to someone if I think it may be having issues.
I would appreciate any thoughts and suggestions from you guys!
All,
I need help re-rooting my phone. I had a stock recovery, rooter phone (to remove/ disable bloat). I received an update from TMobile (the version is still 4.4.2, but build is now KOT49I.D80120g. I could not stop it from applying the update and my phone lost root. I'm now unable to find a way to root it again. Towelroot does not work (your device is not supported) and ioroot says it does not work on 4.4.2.
Please help with what could I try.
Thanks a lot in advance.
wondering if you ever found the solution,. i am on that build as well.
even worse is i can't get into download mode to go back to an older version and install a custom recovery.
Hey Guys, I'm brand new to these forums, and to this whole community so bare with me.
Basically I bought my T-Mobile Samsung Galaxy S5 phone around the time it came out, and I also had installed root on it via towelroot when Towel Root was first released. I did not update the phone at all for a long period of time and everything was working fine, until one day I was browsing under settings and accidentally tapped the "Software Update" button, then T-mobile auto-pushed an update onto my phone.
This update has caused the root on my phone to not work at all (Deemed useless) So I clicked SU and only a black screen popped up when I tried to open the app, so I uninstalled it, reinstalled it then got a message saying "There is no SU binary installed, and SuperSU Cannot install it. If you just upgraded to Android 4.3 you need to manually re-root your device" So I tried to re-root via towelroot method again. It seems the T-mobile update made my phone "Unsupported/Uncompatible" with TowelRoot's obsolete techniques, so now I'm in dire need of help.
My phone tried to push another t-mobile update (This time to upgrade to Lollipop) but it failed after attempting to install it after a reboot. So not only will my phone not update to Lollipop, but I'm not even rooted anymore and am unsure on how to get back rooted, or what to do next since I used rooting as a primary source to store apps on my SD Card. Kind of like i'm stuck in one spot? (Can't update your phone/can't root it the old method)
I'm brand new guys, Please can you break down to me what I should do, in order to obtain root again, and possibly be able to upgrade to Lollipop As well as prevent further pushed T-mobile updates? Here's some info if you need it
S5 Model Number: SM-G900T
Android Version:4.4.2
Kernel Version:3.4.0-262.. etc. (Tell me if you need the full kernel details)
Any help would be greatly appreciated! Thank YOU!

(Will trip KNOX and void warranty)
Or flash a pre-June 2014 KK Kernel, root with Towelroot again, then flash back your current Kernel
Is this the only solution? And also is it the right one? o.o
Can anyone else please give me some feedback on the situation? I want to make sure I do this right, please just a little helps.

Hey I did exactly what you said and it worked I got root back, but I was wondering how to flash back to my current kernel and keep Root?
EDIT: phone is currently unlocked/rooted
I've had a G2 since it almost came out, i don't have nearly the time to spend on here as i used to. Thus i've stuck with jellybean because everything works well and i have it set up how i want but it's a bit long in the tooth and the phone needs to have a full clean factory wipe so i figured i'd take the time to update to something newer.
My thought process is the following:
Save everything i want to keep and take off phone (including titanium backups)
Factory reset phone
Allow OTA updates to download and install
Then root
Then install custom roms (if i so choose)
Now fellow XDAers, anything wrong with my logic? I did do some reading and some searching and it seems like lollipop is rootable with a script and i can install customer recoverys with a script as well. I'd like the phone to still be able to unlock and root my device.
Thanks for any help and/or links to tutorials.
I am not sure but I think OTA updates need a unrooted system with stock recovery.
I had a rooted KK and I could not OTA to LP because the download was over 1.5 GBs!
The best solution may be to back everything up, connect the phone to LG Tools, and choose the upgrade recovery method to get the latest ROM for your phone.
