Trying to install v4.4.4 on my stock --not developer edition-- Droid Ultra. It is currently running v.4.4.2 (19.6.3.obake).
After the download, the phone reboots, gets about half-way through and stops with a message "error!". No other info provided. So far, the MFN doesn't have any answers.
Does anyone have any ideas on how to get this installed?
I have:
-reset to factory specs (via menu with phone booted up) and tried the install
-reset (via vol down, power) to factory specs and tried the install
Always ends with "error!" ..... thanks for any help.
Have you tried to RSD and keep data? I had that problem on the first update and that's what finally fixed it.

Can you offer up the steps to do that? I know how to do a factory reset, but that will wipe the data. Thanks.

May I just say, thank you very much.
That worked ... I am now running v4.4.4 .... and you are right, that was very easy.
Too bad I had already wiped my phone twice ... ugh ... again, thank you!

Updating the radios is surely what caused your problem.
The OTAs are usually patches to existing files, not replacements. That keeps them smaller.
If you open the OTA file and read through the updater script, you'll see that the first thing it does is run a hash against every file it will be updating. It's making sure that every file is stock, exactly they way the patch needs it to be to be successful. Without a check, it could patch a file with changes that break the file and therefore your phone.
In this OTA, the very last thing checked is the modem (radio). Since your was not the 4.4 radio it was looking for, it stops the update before anything at all is patched.
It took so long to get there because there are about 1000 files it checks, if I counted correctly.
You hadn't even reached the actual update part of the update.

I had replaced the radios with stock before trying to update to v4.4.4 .... when that didn't work, I thought the reset to factory specs would take care of that; no joy.
In the end, I love the HouseofMoto program .... that was really easy.
EDIT: Looks like its not MM but some security update, so that sucks but I'd still like to know if anyone successfully got back to stock from rooted 5.1.1
Hi everyone.
I'm trying to find a way to restore my H950 to stock and completely remove any trace of root so that I can install an OTA update. I have tried installing the update with LG PC Suite and LGMobile Support Tool. Both of them say that I am on the latest software (5.1.1 H950v11?). It has been so long since I rooted it that I can't remember what method I used. If anyone has any idea how to flash it back to stock, I'd appreciate the help!
More Details:
I have an H950 (US AT&T) rooted on 5.1.1 and I just started getting an update yesterday saying that I have a system update available. When I tried to download and update, the phone I got an error while the update was still at 0%. When the phone restarted I got the "This phone is suspected in rooting..." Error.
I have tried following this thread [Guide] LG G Flex 2 Stock Firmware (Go Back to Stock) KDZ & TOT Method
but it didn't work. I got the flash utility to run but I still had SuperSU after it flashed my phone and the update still failed due to "Suspect in rooting."
I also tried following this thread [Tool] Easy Restore/Unroot Tool for LG G Flex 2 [09/15/15]!!
but I could not get it to work. The utility just hangs at "Working..."
Anyone successfully used either of these methods on an H950 with 5.1.1 to get back to stock?
Thanks in advance!

You chose cse flash and wiped correct? If you didn't that's why my guide removes everything 100% if you follow it correctly.

CSE flash? Sorry I didn't see that in your guide for the H950 on the AT&T network. I'm looking at your guide and not seeing the CSE Flash unless the LG Tool is the CSE FLash? I had the same problem with SuperSU left over and not able to update. I tried the default Upgrade method, then got a minios OS screen on the the Board method.

It's entirely possible that I am technologically inept, but I am having the exact same issue as the OP. I followed your guide (which was very helpful) for the TOT method, and there is no option to use CSE flash, or at least it's not discussed in the instructions.
I flashed my phone twice using your TOT guide -- pretty sure I followed it to the letter. It completed successfully, but when the phone rebooted, I still had root access. I'm not sure how to unroot this thing so I can receive OTA updates (and maybe sell later on down the road).
Thanks for the help!

Umm, so I found a possible solution on another thread in this forum. Maybe the answer was so simple that nobody thought to mention it. But apparently, you can just remove root access within the SuperUser app; just select "Full Unroot" or "Total Unroot" from settings. Then run this TOT flash, and you should be GTG. I am trying this now and will report as to whether I am successful.

Rooted or not you should be able to go back to stock. And CSE flash is for the kdz method of lg flash tool. Which I didn't realize what model they were needing help with. Also with the H950 LGUP should be used instead of normal flash tool to avoid any issues with the flash tool.

Hmm. Thanks for helping us out. So I am kind of confused. I reinstalled the Tot file using LGUP, and it completed successfully. I selected "REFURB" mode, and it completed successfully. But after it finished, my phone is still rooted. (I verified with root checker.) I just want to go back to stock so I can get OTA updates (and MM hopefully, when/if AT&T releases it). Now my phone won't get OTA updates because it says it's "suspected of rooting." I bought the phone used off of Swappa, so I'm not sure how exactly the original owner rooted it.

At this point you'd be better off waiting for a KDZ of MM when it comes out for the H950. (But remember, root will probably never be achieved for our devices on MM, if that's something you care about).
I remember buying TWO H950s. Both needed the OTA for the latest Lollipop. But despite several hours, several methods, and several hours at the ATT store, I was never able to get OTAs working on either of them. It was impossible.
And supposedly impossible for several other users on XDA, who couldn't get OTAs working for their ATT Flex 2's. So even if you manage to unroot, don't get your hopes high believing OTAs will work.
Did somebody ever able to go back to stock (H950) from rooted 5.1.1? Where did you get the TOT file?

According to this post you just need the flash tool and kdz but haven't tried it yet.
I just attempted it and ended up erroring at 9% with error 0x2000 CEFS:Initalize() :/ Attempting a redownload maybe I have some bad files.
*edit*
Was able to use uppercut by codefire(thread) to flash this kdz. posted in the other thread for this kdz also.

Sorry i typed that twice because i trashed my first post...
Thought i included it but apparently missed it the 2nd time
Im stock unrooted. So this was tested on a stock unrooted vs995. So ill be rooting in the near future. If someone doesnt test before me ill do it, but the uppercut allowed lgup to flash the vs995.

Hey bro I decided to test this myself.. I was unlocked and rooted on vs995.. I just used the uppercut and LG up I did the upgrade option in lg up..
And it worked.. I didnt lose my data r apps but root is gone.. I will now see if I can root it again with Dirty Santa which I should Security patch is Nov 1..
Thats what i was on b4 when I rooted the first time.... Also if anyone can tell me how to pull the system.img and boot.img???? If i can get those
Ill give files to Tilde88 so we can have a updated Rom..

Thanks for keeping us updated. I'm probably going to stock restore too, currently on the unlocked deodex 996.
When you did the restore, did you wipe data before you started? I think I'm going to wipe and format storage since I'm on the vs996 Rom. Unless there's a way to wipe data in the stock recoverym

I tried to use Uppercut but it kept giving me an error that no devices were found. I have adb drivers installed and the LG mobile driver installed, nothing showed as error in device manager. Did you have any issues like that?
Edit: Weird, tried it again and it seems to work.
Thanks a million everyone, I finally fixed my Lg v20 vs995! I kept having failure trying it with Uppercut, but I finally saw that I needed to install 3 files to get it to work correctly, 1st you need the kdz file: VS99512A_06_1114_ARB00.kdz, next you need to install 2 driver files, LGUP_Store_Frame_Ver_1_14_3_3.msi and LGMobileDriver_WHQL_Ver_4.1.1.exe, and of course have UPPERCUT.exe. Finally after installing all of the correct drivers, and loading UPPERCUT, using the VS99512A_06_1114_ARB00.kdz, I finally got it to work and you have to choose "UPGRADE" in UPPERCUT, but I completely restored my phone to factory!!! What a frickn blessling, I am so happy, because I was trying for days to fix this..... and I actually threw this phone in the trash, hehehehehe, but something made be take it out of the trash an hour later, THANK GOD!
[GUIDE][UNBRICK] Patch LGUP to unlock features & unbrick V20 (Variant mismatch fix)
Team
After a flash gone very bad, I got myself a brick with a locked bootloader & wrong viariant in LGUP [US996-->H990ds].
In my attempt to recover I tried several silly things including flashing another variants firmware, however I managed to find a way to unbrick & restore the original firmware.
I ran into the G5 thread by @smitel, and did something similar for our V20 by patching LGUP.exe & our phones LGUP_common.dll with HxD Hex editor (my patched files attached).
After doing this I was able to force-flash either partial or full stock kdz using the [PARTITION DL] option, bypassing the variant mismatch warning (Phone was fully recognised as US996).
It even corrected the partition layout (H990DS is different to US996).
Credits about the original patch should go to @smitel

I very glad to read you managed to save your phone! What you've found though may potentially be rather more powerful than you think (I don't know how powerful you think this is).
Instead of the complex DirtySanta procedure using DirtyCOW/CVE-2016-5195, it should be possible to use this to directly rewrite aboot. At which point you've greatly simplified the procedure, as well as opening it up for phones which lack a sufficiently early KDZ (Sprint which has no KDZ, H990TR which January is earliest).
Does still need a bit of experimentation to confirm though...

I'm aware of the great value of my discovery. (Almost makes us unbrickable)
I was able to upgrade official firmware without loosing root or twrp.
To be honest I haven't tried flashing aboot or unofficial kdz, but if possible it unlocks full potential....

I'd hardly rate it as "almost unbrickable" (`dd if=/dev/zero of=/dev/block/bootdevice/by-name/xbl2`; you're toast), but does give additional tricks.
There are a few other methods of doing firmware upgrades without losing root or TWRP. Both extracting the KDZ and turning into a flashable .zip, or my tool for directly writing the contents of a KDZ file.
The real potential here is if this can be used to install the DirtySanta aboot image, then it is a much simpler installation method. This should also be able to avoid the unreliable installing TWRP via `fastboot flash`. Additionally since this isn't relying on DirtyCOW/CVE-2016-5195 even up to date phones should be able to use this.
You're on a vanilla H990 single-SIM? Rooted via my method? Other method?
I agree that this method won't save you once you lose "Download Mode" that's why I used the word "Almost"
I have a dual-sim H990DS, originally rooted with your method (even paid for your bounty. although hadn't pledged).
I had a US996 rom fully flashed on my phone (with different partition layout), & I was still able to go back using this method.
Well, I will be the guinea pig
I got my H910 back from LG, and of course dirtycow was patched, so if this can flash the us996 debug aboot and not brick my phone, that will be something.
EDIT: @emdroidle I am not at home, but looking at your repo, it looks like you are now able to package back up a v20 format KDZ. If that is true, and this patched LG UP can ignore the signature of the KDZ -- this may very well be one of the greatest finds in a long time. Really looking forward to testing it to see....
It worked on my device. thank you very much

I have a h910 device and I have kdz to h910pr version. But I can not unlock device to root. And I used this way. It can kdz us996 files without problems
@bilong9 So you flashed a stock US996 KDZ onto your H910 with this method, or did you repackage a KDZ with the US996 debug aboot?

I already knew that you can flash any V20 variants stock rom if the kdz is officially signed by LG (my phone was fully recognised as US996 when bricked & was able to flash H990DS firmware).
What I don't know is if an unofficial .kdz (not signed by LG - eg compiled with KDZ extractor) can be flashed.
I strongly suspect it would but haven't tried it yet.
I wish this had worked for me. Both LGUP and LG Flashtool 2014 both fail every time. With your patched files for LGUP I got stuck at 4% and then it crashes. Before I used the patched files I got stuck at 9% and then it crashes. I'm on US99610H and I want to downgrade but have had no luck and I can't seem to find how to solve the issues I'm having.

Perhaps try one partition at a time, or try disabling antivirus (my hex edit invalidates the files signature hence some antivirus may classify it as malware).
To be sure I would try flashing US99610H again (to rule-out anti-rollback)...

already attempted it yesterday. it dumps partitions fine but installing partitions is wonkey. it wouldnt flash my boot.img but would flash its header so the phone refused to boot. crashes when you try to flash aboot on.

Alright, so I downloaded the US99610H KDZ and I just hit Upgrade and It did say something about Anti-Rollback check passed and the LGUP program didn't crash. Is there any way to go back to a previous firmware version or am I stuck with an Unrootable V20?

That hints that anti-rollback is active on your phone (you can flash your current firmware or a higher version - not an older one). Try flashing system only & see what happens (cannot guarantee you won't get a brick, but I believe its highly unlikely - you have been warned)

Is your phone still recognised?
I suggest you retry with another cable (try the lg stock), updated drivers etc. I have flashed aboot many times on my H990DS.

Alright, so if I just flash the system while clicking Partition DL, I run the risk of having a brick. If I don't get a brick would that somehow deactivate anti-rollback if I just flash the US99610H System?

Thanks! Any chance you have a copy of the 5d firmware, too?

Thanks. I just reflashed 10d (my mistake when I said 5d) with LGUP and uppercut. I guess you can't boot to TWRP without having flashed it first or something so I'm as good as I can be for now. Hope your issue clears up.
I realized I used a wrong command to flash boot instead of recovery.
Fortunately, I saved the 10d full ROM and I just flash it with LGUP and use correct command and install Magisk again. However, I had to wipe the machine due to mistake, but I have a backup a month ago so data loss isn't that bad.
10d seems to be a bit faster.
Full ROM + dll + instruction how to copy.

Thank you Soo much. I just got my 3 plus and in less than 24 hrs managed to f it off completely. My girl was talking to me and I was only paying half attention to what I was doing and wiped everything. No OS of course and I had just gotten it flashed with twrp. Needless to say I feel like an idiot because I hadn't gotten a good backup. I have the .lbf from my PC but I couldn't get bridge to recognize my phone. Lg up would but I need .kdZ

DLL says it's invalid. Anyone been able to use it successfully?
Edit: Nvm. I just had to reinstall UP (messing with DLLs from flashing other models screwed it up, I'm guessing). Worked great after
alright I have flashed the kdz file from multiple souces including this one, nothing changes on my end says completed but nothing changes, except an error message everytime I open up any app says App Updates has stopped it's getting annoying, my camera is not as good anymore either its more of a blur than anything, what do I have to do to restore this phone back to original settings and original software where I start completely over, this kdz did not do that it kept my apps, it kept everything and then gave me that error
LGUP I could only do upgrade not refurbish it just does not take it as a refurbish something with the file structure I think but that's the only option it would let me do

plug in your phone, unzip this and you will see 2 lgup icons (red). right click on the developer("D" on it) icon and choose run as administrator. notice i skipped uppercut. if you do it this way it is not needed. you have many more choices. it is even possible to put the os of one model running the same hardware into another effectively changing the model. there is no device check. If lgup refuses to do something, close it and boot it up again. Sometimes it helps.
