Tmobile LG G2 - Can't unroot to Jellybean - General Questions and Answers

I have rooted my Tmobile LG g2 and it has kitkat 4.4.2. I want to sell it to a friend and when trying to get it back to stock I only have the 80120E.kdz, so when using the flash it says I have the latest version and will not unroot the phone. I followed the link http://forum.xda-developers.com/showthread.php?t=2672076 from here, but the d80110c doesn't download, it just takes me to an html with all the scrabbled code (or rather code I have no clue of what it means). Downloaded the zip file, but it gave me a .tot file which I don't even know what it is, but it's certainly not a kdz.
Can anyone tell me how to get the jellybean version, so I can get it all the way back to when I bought it (Jan 2014) and the let it do the OTA from stock?

[Q] Stuck on V10d

Hi guys,
I have a bit of a problem with my optimus 3d, ive had allsorts or roms installed, custom and stock and i have reflashed back to stock 10d using the binary file and lg flash tool, no problems there, however now ota update and lg update program are telling me I have the latest version! I'm pretty sure 10K is the latest version but my phone is having none of it. The last rom i had was the leaked GB rom and yes i have reflashed the froyo baseband when i went back to 10d. Any ideas why my phone cant see any updates?
Thanks
P.S. My phone is and unlocked Euro open version
If you have EuroOpen version of phone latest firmware is v10d.
You can flash v10k using kdz method in my sugnature.
Thanks for that mate, i'm glad someone knows what the most current firmware is, i'll probably just wait for gingerbread and get it ota when it's released
V10k Was latest EuroOpen, but LG deleted it from server.
Let me guess... LG deleted it with no explanation as to why?
I don't know In many countries v10k is the latest firmware.
And P920 is removed from the list in LGMOBILE support tool in the EuroOpen tab.

[Q] OTA update Available but not able to update due to rooting.

Hello,
New Android 5.0 Lollipop OTA update for D838-HKG sets is available. But everything time i try to update it gives an error, says, suspect of rooting and Update service is not available for rooted device.
I have unroot my device even after it is giving similer error. Please help to update device.
because you already rooted it once. unrooting with su app. will not going to change that. if you want flash d838 lollipop update via lg offline flash tool 2014. look for a kdz and flash it that will update your phone to lollipop.
bartdotnet is right. I had the same problem too, and installed the update thru the LG offline flash tool
the most recent KDZ version is v20a (for my phone D838 HKG), and you can download it from http://lg-phone-firmware.com/ (it's about 1.2gb in size)
search for a tutorial on using the flash tool, and you're done!
android version in v20a is 5.0.1, and the battery life is worse than before, so think twice before taking the plunge

[GUIDE] Installing and Rooting H950PR 5.1.1 from 5.0.1 10b

I caught the deal on ebay for an inexpensive Flex 2 not so long ago and, of course, the first thing I set out to do was update and root it.
The stock image ran 5.0.1, w/ firmware H950 v10b. I attempted an OTA update several days in a row, being told each time that none was available (the phone is AT&T branded and my service is through AT&T), but eventually grew impatient to get that sweet, sweet 5.1.1 action going.
After attempting to flash the 5.1.1 v11x rooted system image provided by randrew87 (here), I was greeted with a nifty little 'Security Error' boot screen and pursuant loop. Sadly, I wound up flashing the stock system dump I created following that tutorial to get back into a usable state.
Left with no other options (assuming, correctly, that I'm being impatient with OTA), I decided to try the 5.1.1 H950PR v15a firmware.
NOTE: Though I chose to flash the unrooted 5.1.1 H950PR image first, you may not have to complete this step; I'm not sure, but it's possible that you could simply write the rooted image instead.
First, I followed this wonderful tutorial by Sj12345: [KDZ] H950PR 5.1.1 compatible with ATT H950 with Video!!!
My initial plan was to write the unrooted system image and root using any of the available tutorials. Unfortunately, I couldn't get any of the tutorials to work for me as my device simply refused to allow r/w operations to /system while using the COM interface, regardless of my approach.
After a little trial and error, I discovered I could write the rooted H950PR-v15A image, provided here by Sj12345, and achieve root.
Here's how:
Download rootedsystem.img (from Sj12345's post)
Download LG Root Tools.zip (attached) and extract to a folder
Copy to the root of your internal sdcard via means of your choice (I used MTP mode and Explorer to drag and drop)
Power off your device
While holding VOLUME UP, insert a USB cable.
Open a Command Prompt window where you extracted the archive (easiest way is by holding Shift then right clicking within the folder > Open Command Prompt Here)
Double click ports.bat (included in the archive). Find the diagnostics port (in my case, COM4)
Type the following:
Code:
Send_Command.exe \\.\COM4
(replacing 4 w/ your com port)
You'll be greeted with a '#' prompt, terminal-style. From there, issue the following command (thanks to randrew87's thread):
Code:
dd if=/data/media/0/rootedsystem.img bs=8192 seek=53248 count=534528 of=/dev/block/mmcblk0
The operation will take a couple of minutes. Once complete, you'll again be greeted with the '#' prompt.
Type LEAVE (all capitals), and hit enter. Your phone will reboot and have a clean, rooted image installed.
Profit.
This guide is obviously very specific, requiring H950v10b 5.0.1 firmware on an AT&T flex 2, no OTA availability, and a myriad of other issues (such as /system being readonly). My hope is that this will aid others who don't fall exactly into the parameters described in existing tutorials.
Thanks again to randrew87 and Sj12345 for their great posts and work; this thread is merely a slightly different approach to their pre-existing methods. They did the work, not me!
Hope this helps someone!
Regards
Smith
Any reason to go with h950pr instead of Ota 5.1.1 or simply just out of frustration of waiting? I'm asking cause I should get my att flex 2 tomorrow.

PR rom does not have all of the AT&T bloat. However, the main drawback that I'm aware of is that there is currently no way to go back to official AT&T. Seems everyone who has tried to do so has ended up with a bricked phone. You may also run into issues trying to get warranty honored once you move off the official AT&T version. So.. caveat emptor and all.
Most folks who really want the 5.1.1 OTA have managed to do so by laying down the minimum amount of cash for an AT&T gophone plan then getting on the horn with AT&T's tech support to have them manually push the update through.
Hi smithisize, thank you for your guide A very basic question, how do I know which version of root file to use? I just check in About Phone > Hardware Info and it said the phone was LG-H950.
Smithisize,
Thank you for the guide. I have a question.
My H950 has H950v10d 5.0.1 on it. I am just guessing that it would work for any 5.0.1 version.
Is this right?
Thanks again,
MB
Same here...
As Meatbag_1 written, I have the H95010d release witch rom we take???
Yes it will work for atnt g flex2 on atnt firmware 5.0.1 all subversions

Isn't the latest software version for the US h950 the "v11x" version? Is it possible to flash that instead of the PR firmware?
No
Only OTA from AT&T
No flash

I tried rooting my newly flashed 5.1.1pr with this method and got authentication error 11. I had to reflash to get out of the boot loop. What am i doing wrong?
Thanks man. How can i root it in the first place?
I was trying HERE but i do not know which to dowload, if H950 V11X or H950 V11Z ... can you help me with that?
H950v10d 5.0.1 not rooted. Tried method from OP using H950PR 5.1.1 rootedsystem.img. Now I am stuck at Security Error bootloop. Where to go from here?
Nevermind... Phone started non stop bootlooping with no way to shut it off. So, I smashed it to bits.

First Flash the KDZ file from here: http://forum.xda-developers.com/g-flex2/general/kdz-compatible-att-h950-t3180847 using LG Flash Tool. I use Build 03/07/2014 Offline with modded hosts file.
Then download the Rooted H950PR-v15A image file from the link provided and continue with the guide.
btw: thanks for adding; you type: "LEAVE" in caps. No other guide seemed to mention that and when I did, it was the only time it actually rebooted my phone..:good:

I was able to get to download mode, but it would just go into bootloop after entering download mode. I have another on the way, so hopefully things go better this time. Will try the method posted above.
Can you send me a link to download "LG Flash Tool Build 03/07/2014 Offline with modded hosts file?"
thanks
Your can download it from here:
http://forum.xda-developers.com/showthread.php?t=2797190
I ignore the warning about the kdz having to be in the flash tool directory. I just browse to the location I downloaded it to, never fails.
And about the hosts file, this version doesn't seem to need a modded hosts file as it won't try to connect. That was sth I had to do from an earlier version a long time ago and forgot.
Fyi: I soft-bricked my phone like many others having the same security error because of tring to install the rooted system image file for 5.1.1 over the top of 5.0.1. And to reboot from download mode I had to hold all three back-buttons.
To install Xposed framework follow this guide: http://forum.xda-developers.com/g4/themes-apps/guide-installing-xposed-locked-t3181593 but USE Flashfire 0.24 or earlier as the latest beta version won't flash sh*t on this phone (or the G4)
If you need detailed instructions let me know.
Good luck!
PS: I bought the AT&T version(5.0.1) for the 3GB of RAM but I live in Australia so couldn't get the 5.1.1 OTA which is why I had to do this way, but apparently if you flash the 5.1.1PR kdz over the 5.1.1 AT&T OTA update(just to avoid AT&T bloatware) it will brick your phone.
so i just purchased the the g flex 2 much like yourself and i have everything ready to go. My only concern before doing so is what to do after the soft brick. Once you reboot from download mode is, doesthe phone start normally? or is there an extra step since you talked about USE flashfire
PS. i dont care to root the phone or is it necessary for this all to work?
Updated H950 5.0.1 ATT to H950PR 5.1.1
had the lg drivers which i downloaded using the lg suite from the LG website ( i originally tried to update my phone using this method...didnt work obviously so i came here)
Used lg flash tool 2014 as provided from this forum.
Placed H950PR15a_00.kdz in the place where it asks in the tool
followed the guide, i had the phone in debugging mode and it was just on my homescreen unlocked, phone shut off restarted into download mode and started the firmware update, phone itself reset at 100% ( keep it plugged in)
Lg flash tool was still going at this point it was around 90%, phone was resetting when the lg flash tool hit 100% and then crashed ( had a panic attack really ) i kept the phone plugged in and it reset to the lg boot screen
Leaving it plugged in , in spanish i saw that it was optimizing my apps, went to the tutorial within the phone and it resarted again... so i started having another attack, i then saw the boot screen claro at this point i unplugged my phone and it is now on 5.1.1 h950PR i have not rooted the phone before hand it was stock from ATT.
Thought i put my experience in here with this phone in hope to ease some tension. it was easier than i thought even though the tool crashed at the end, phone had already accepted the KDZ at that point

Thanks mate. Ran into this problem when flashing the ATT version before flashing the PR version like I was going to. This solved it, thought I'd wrecked the phone for a sec.
Much appreciated

Yes you can. The LGH631 and the LGMS631 are both the same devices essentially, same exact hardware on the same exact network. I personally used the 5.1.1 T-Mobile bootstack and the returntostock zips which I flashed via TWRP after rooting. Stay stock unrooted 5.1.1 and then jump on your wireless network and wait for the update. I was able to keep my Metro apps this way.

I don't believe LG Flash tool works anymore, at least not for our phones. I was lucky enough to get Marshmallow through the OTA after reverting back to stock, but when I first got the phone back in October last year the first thing I did was try to root it and bricked it. If you download LG Bridge there's an option for "Update error recovery" on the bottom right of the software update tab and you can sideload a kdz file there.
Here is where you can get USB drivers for the Stylo.
Thank you. Just trying to get this figured out in case Draken is unable to get his zip fixed. I'm currently rooted on 5.1.1 and trying to go to marshmallow
Not a problem. Happy sideloading, but keep in mind that a kdz is a full return to stock and you'll lose everything on internal storage and you'll be setting it up like a brand new phone. Then again if you're going to root it using the guide on here you'll lose all internal storage data anyway so...
Regardless, good luck!

There is a method to flash the T-Mobile kdz file 10j and then OTA update to 10L and then to MM.
I was rooted on Lollipop/Katana ROM and did this method and am on MM/T-Mobile variant, then rooted after MM update.
LG Flash tool was used to flash the Tmo kdz 10J file (lollipop).

Hey,
LG UP is a new and easy tool from LG Official. It can flash kdz/tot/dz files.
You can use "LG flash tool 2.0.1.5 or above" to flash kdz/tot/dz files.
The LG flash tool 2014 is a tool modified by some one from Vietnam, I did not test it.

Unlocked G3 D850, no OTA update?

EDIT:
What files do I need from storagecow link in the OP to do a 100% proper flash? The .zip only contains boot.img and system.img but I've heard you need the modem file as well?
There's others on storagecow like patched20fboot.img? rpm.img? tz.img? Should I grab all the files and put them in a zip and then flash? Or should I flash them one by one in a certain order?
I GREATLY appreciate any help. Please note I'm only after official LG firmware, no cyanogenmod or anything.

Hiya. Brand new to XDA forums so I apologize if this has been mentioned before.
I'm gonna make this as quick as I can. I bought an unlocked LG G3 from ebay
Opened it up and turned it on, first thing I did was check for firmware updates because it was still on KitKat. Nothing for some reason. (if you know why please answer in your response)
I'm new to rooting/flashing firmware but I did my best at researching on how to flash it to Lollipop which I successfully did but I had a few small problems afterwards.
Google Chrome refused to update no matter what I tried, taking screenshots wouldn't work and I couldn't delete the firmware files on the internal storage. So I ended up reverting back to the stock KitKat room, unrooted with no TWRP.
This phone is gift to someone so I'd like it to be in perfect working order, but I would like it to run stock LG Lollipop as well as Marshmallow when it comes out soon.
First question is, is there a way to update the firmware with an official LG software or do I have to flash it? I've heard when you're 2 firmwares behind OTA no longer works.
If not, what files do I need from storagecow (I can't post the link cus I'm new) to do a proper flash? The .zip only contains boot.img and system.img but I've heard you need the modem file as well?
I GREATLY appreciate any help. Please note I'm only after official LG firmware, no cyanogenmod or anything.

You'll have to root, and use a custom stock rom. It'll only OTA update if you insert an active AT&T sim.
