It's a new T-Mobile LG G2 that I decided to try to root, but realized that I had installed the OTA, disabling me to. During the process of trying to downgrade, however, it failed. After trying to restart the phone, the phone simply goes back into firmware mode. I have no idea of what to do. Please help!

So, I've done this before, and I've never bricked a device until now.
I tried installing a custom rom for my Galaxy S3 on Verizon, but when I restarted, it says this:
System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help.
I can't get into clockwork, or any bootloader. Any attempt to do anything brings this screen up.
Now, I can get into the Odin downloader. (Power, volume down and home). But, I can't figure out how to get a Rom to load. This is where I am stuck. I have downloaded a few roms, all stock, but none of them want to be recognized. I have no idea where to go. I've been downloading stuff for 5 hrs and nothing has worked, so now Im going to the forumns. Any help is appreciated.
I have the Verizon i-535 Galaxy SIII.
You did not brick your phone you failed to unlock your bootloader. There are 2 guides in the android dev section for rooting.

Odin back to stock and next time after rooting make sure to use EZUnlock 1.2 to unlock the bootloader BEFORE loading a ROM

So I had Root on 4.2.2 but took the 4.4.2 ota. I've tried using IOroot25 over and over and over again but to no avail. I either get stuck on the locating device screen on my PC or I end up on the adb sideload screen on my G2. I've done everything but wipe the phone and I don't want to do that because its been flashed to a different carrier. Anybody have any advice? I've trolled thru all the forums on this and I cannot get anywhere. I'm desperate :crying:
Good afternoon all if anyone could please help I'd greatly appreciate it!
So I just bought a Sprint Galaxy S5 from ebay with the assumption that with some customizing I'd be able to get the phone domestically unlocked. I got the phone and it was already updated to 5.0 Lollipop so I followed this tutorial to get the SSU.apk to actually work
http://forum.xda-developers.com/spr...locking-sprint-galaxy-s5-g900p-t3085624/page2
After a lot of time I was successful at rooting the phone and was able to downgrade to 4.4.4 but the tutorial calls for 4.4.2 but it seems that 4.4.4 was the only fw that would successfully install.
But now here's the problem I was able to obtain the domestic unlock code through Sprint but now the activation/update app doesn't work and doesn't open automatically the way that the reps said it would,. I've tried to reset stock through Kies but Kies doesn't recognize the phone. I've also tried to use Odin through out this process not only to reset back to stock but also downgrade the fw and the modem. The really annoying part is that small PDA/AP updates and installs work fine but when I try to Odin the original tars it always fails 100% getting a "sw rev check fail aboot fused 2 binary 1 " error on my phone.
I really don't know what to do at this point, and it seems the error is associated with a soft brick but the device still powers on and boots.
I thought this would be a pretty straight forward process but I've hit the wall and am losing my mind, I need help!
P.s. I flashed 4.4.4 fw with CWM and the device is still rooted
Thanks
i got the phone from my friend and he told me the root was stuck on there and it couldnt be taken off. Is there anything i can do to show whats currently on it to see if theres a possible way to remove it? the phone keeps randomly restarting on me and not reconizing the sim when it comes back on. i cant afford a new phone right now and was just wondering if the root could be causing problems? thanks in advance!
Hi !
The safest way to have a working device is to use this thread [Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ & TOT Method With LGUP
