Error message when trying to update with LG Updater

Hi everyone!
First of all, sorry if this as been asked, tonight my Google skills didn't help me find an answer.
A friend of mine owns a LG Optimus 2X (P990) bought from Fido in Canada. Currently she's on Gingerbread and would like to update to ICS (which is the latest stock rom available from what I read)
She wouldn't get the software update OTA so she tried downloading the LG Updater software from LG directly. The software detects the phone and says an update is available.
At some point, a popup appear suggesting to make a backup. So far, everything is fine. Once the backup is done and she click the "Start upgrade" button, she gets this error message : "An Unsupported operation has been attempted"
Anyone ever seen this before? Is there a way to upgrade her phone without using the LG software?
Since it's not my own phone, I would prefer not rooting it.
If rooting is really the only solution? What would be a good guide to read to do the update? (I did read a few sticky posts... 1 is the all in one tool kit... it explains each feature, but is not really a guide and I still have some questions unanswered after reading it. The other guide I read, the download links are broken)
Thank you

i want ICS too on my phone, and use LG tool several times but unsuccessfully, it is like that not working or i dont know...
you can use AIO tool, it is too easy to work with it, just follow instruction and install correct bootloader and thats it.

What would be the right steps?
Use option #4 to repartition the device for ICS and then option #7 to flash the ICS stock rom?

here, in this link is explaination how to root and install ROM:

Alright, that didn't help at all.
First of all, I wanted to flash a stock ROM... the guide tells us to install CWM and we got stuck at the part where we have to flash the ROM because it would seem CWM won't take the KDZ (or bin/fls) files.
Now we can go to the SW Upgrade mode without the battery, but the smartflash utility time out after 3 minutes and end on an error.
We can also go to CWM with the battery... but with no apparent way to flash a stock rom.
We're stuck at the moment.
Edit : So in the end we flashed only the BIN file instead of both BIN and FLS. No more errors and the phone rebooted correctly under ICS! Yay!

It's fixed! We didn't flash the FLS file (which would be the baseband?) but the phone still booted properly and connected properly to the cell phone provider.

FYI: Taking OTA while rooted w/ twrp.

I have been on dfuses stock rooted 4.4.2 D95920h for quite time now. Today I decided, after reading that others took the T-Mobile updates and were able to regain root, to take the updates. I first used the stock D95920h.kdz and the lgflashtool 2015 to flash to stock no root and no custom recovery. I took the first update (D95920m) and rooted with towelroot no problem. I then had to unchecked in the settings the "use network time" so I could manually change the date ahead to Jan 20th. That's the earliest it would let me search and take an update again. So I downloaded the D95920s update and let my A.D.D. take over and used the freedom flex.apk to install twrp. And later on I clicked install update not thinking about having root or custom recovery. And to my surprise the D95920s updated just fine as if my phone was stock except it updated through twrp. I was shocked. I then tried to reroot with no success. I tried everything from ioroot, stump, saferoot, towel root, even tried all the commands manually through adb. No luck. So I flashed the D95920h with the lgflashtool 2015 again and started over. This time rooting and installing twrp first and then only upgrading to the D95920m so I could root and push the twrp bumped.IMG. I'm going to dissect the D95920s update and edit the meta-inf folders updater script to not reboot when completed. Then before I reboot out of twrp and lose custom recovery I'm going to try to flash an updated supersu.zip as well as my flash able twrp.zip. to try and see if we can regain root and custom recovery on the latest update.
Buy moral of the story the update did its thing using twrp and didn't reject it. Or abort it. Even the the second go around when I went back a few versions and updated again it did just fine with twrp and I was not able to maintain twrp through update but was able to use twrp to update. Weird. I don't suggest trying this. My discoveries were purely accidental. And lucky I didn't end up with a mess to try and figure out how to get back up and running.

Matt, can you share lgflashtool 2015 and how to use it? I updated to D95920s and lost root, twrp, and download mode.

Yeah sure... It's self explanitory... But yeah ill upload it to drive in a lol bit and post a link.. It's the same basic tool as the lg flash tool or pc suite's restore upgrade errors tool it uses. It just doesn't go through all the update checks and checking the Internet for updates for it and the firmware its flashing..... I found it in the G2 forums... Can't remember where... But a dev in the G2 forums modified the lg flashtool to just work no questions asked.. No software upgrade check. No flash tool registration key check. No "must have internet connection" check... All that is required is that you already have the stick firmware you want it to flash... Preferably flash same version you're running. KitKat - KitKat... Jellybean - jellybean..... No need to be in download mode, it will reboot you to download mode ittself.. Figured that out when I went to the d95920s version and couldn't root... So I flashed the stock 4.4.2 kdz abs starts all over.. I've restored it 3 times this weekend already.... Lamo

[How-To] Unbrick or Flash Back to Stock(NCE) - G900A Only

***The steps below will work on all Bootloader versions except OC4(Android 5.0), Do not use this process if you have taken the OC4 ota update!***
1. Download the G900A_Downgrade_to_NCE.rar and extract the .tar.
2. Go into Download Mode by pressing and holding the Home, Volume Down, and Power keys on your device until the phone powers on and displays warning screen, then press Volume Up key.
3. Flash the G900A_Downgrade_to_NCE.tar using Odin's PDA slot(AP in Odin v3.09+).
Note: The most common cause of an Odin flash failure is a bad usb port or cable. Please check before reporting a failure!
Attention! If you have taken the OC4 ota update and need to unbrick after attempting to downgrade try flashing the: G900A_OC4_Stock_Partitions

So why is it that the g900a is the only gs5 that can't downgrade from 5.0? even Verizon can???

I had a different Downgrade to NCE file. Tried this one and my phone is back up and running. Phew!! Thanks so much!!

Is it safe to flash over ND3? I'm not recieving any ota. Will I receive Ota After flashing this?

Phone gets stuck up!
For some reason. i tried to unbrick my phone from the rooted stock firmware 5.0 and it ended up with the boot loop. Already tried the downgrade to NCE. Now it gets worse because all I can see so far is the logo of ATT and that's it. Anyone could help me out with that???

I'm sure you probably already tried this but if not pull the battery for a few seconds and then try going back into download mode and try the process again.
How did you upgrade to 5.0 (which method) You may have to provide more detail, there are a lot people who have way more knowledge than I do, but I hope this helps
Good luck and give the forums a search

Thanks for the reply! I actually upgraded to 5.0 by the flashfire method since before that I already got the rooted 4.4.4. Just yesterday, when I left my phone for a while and came back, it started to stick with the bootloop, , the only method which could help it out is to plug it into the power source. I tried everything which includes removing battery and wiping factory downgrading, flashing original firmware, reinstalling the OTA 5.0 update through sdcard. None of that worked. If you have any information to help me out,I would be way happy to listen! Thank you !

I've had this same problem. Are you still bootlooping?

THANK YOU...
I'm with archie above - I tried a different downgrade file and it didn't work either - this one DID.
Thanks so much...

Thank you so much for this. Worked perfectly for a downgrade from 4.4.4. You're the best!
Currently installing updates OTA.

Hi muniz, I posted in your KeepRoot for 5.0 thread and then I saw this one. My phone seems to have spontaneously softbricked (system crashes and then it bootloops). Will flashing the stock 5.0 make me lose root?
EDIT: Fixed with a battery pull!

Just to clarify, my S5 is on the OC4 build. Will I be able to downgrade to KK using the above file, or is it ONLY to fix a device that got bricked while trying to downgrade? If the latter, are OC4 users just hosed? I have scoured this site, but would appreciate links to any instructive threads that I may have missed. Thanks!

[RESTORE][TOT] Sprint LG LS991 ZV6 TOT

Hey guys,
Thanks for bringing this to my attention.
Be aware that this one includes factory reset protection. Those of you having issues trying to revert - this is probably why.
I forget how this works to revert but would check out the G3 forums to see how this was handled.
ZV6 (and now ZV5) location:
http://rwilco12.com/downloads.php?dir=Files/Devices/LG G4 (LS991)/
Sprint notes: https://community.sprint.com/baw/message/1009786

yes, as garwynn has pointed out... there will be issues downgrading if you flash this zv6 file.. or take the zv6 ota. the bootloader in zv6 updates the bootloader versioning to "v2".. while zv4 is "v0" and zv5 is "v1".
ZV6 TOT is out!
Thanks to @garwynn we now have the ZV6 TOT. I have also broken down the TOT and uploaded the individual partitions.
Changelog:
Minor User Interface updates
Google Security Patch: Stagefright and Factory Reset Protection applied
ZV6 also updates the bootloader version to "v2"
--TOT can be downloaded *HERE*
For those familiar with LG's.. this is flashed the same way as previous models... LG OG, G2, G3 etc etc.
1. Download LG Flash Tool. Swap the included mega.dll (click here to see video)
2. Download the LGFLASH_LG_G4_CODEFIRE.dll
3. Download the ZV6 TOT and unzip it.
4. If LG drivers are not already installed, download and install them.
5. Place phone into download mode
6. Set phones serial COM port to COM41 in Windows Device Manager. Unplug USB cable then plug it back in.
7. Run LG Flash Tool.
8. Select LGFLASH_LG_G4_CODEFIRE.dll for DLL, LS991ZV6_00.tot for TOT and check off "BOARD DL"
9. Hit OK to continue. Now hit the yellow start button. LG Flash Tool should now perform a CRC check on the TOT.
10. Unplug the USB cable again then plug it back in... wait 5-20 seconds and hopefully the flash should now start.
When it finishes it'll boot into miniOS. Hold the power button then press the "Normal Boot" option on the screen.
The above steps are "to the point" and there's not much hand holding so new LG flashers may be a bit confused. Feel free to ask questions in this thread and hopefully other users will chime in and assist with specific questions. But for extra help here is a how-to video going over the process. Only differences is phone model and TOT/DLL files used... rest can be applied.
Also here is a G4 Return to Stock thread... the lower section of the OP has step by step directions and screenshots for the entire LG Flash install process and TOT flash.
--Individual ZV6 partitions to flash manually can be downloaded *HERE*
--ZV5-to-ZV6 OTA update.zip *HERE*
You must be on ZV5 and have a stock recovery and stock system partition for this to work.
Directions:
1. Rename downloaded .zip into update.zip
2. Remove USB cable from phone.
3. Power phone off.
4. Press and hold volume down + power until you boot into stock recovery.
5. Select "update with adb"
Code:
adb sideload update.zip
Alternate Directions to skip using ADB (needs microSD card):
1. Format microSD card as EXT4.
2. Rename downloaded .zip to update.zip
3. Move update.zip onto external SD card.
4. Power off and boot into stock recovery (vol down + power)
5. Select the Update from SDCARD option.

very nice, now the soft Bricker can restore back to ZV6....

autoprime said:

but yes, as garwynn has pointed out... there will be issues downgrading if you flash this zv6 file.. or take the zv6 ota. the bootloader in zv6 updates the bootloader versioning to "v2".. while zv4 is "v0" and zv5 is "v1". for some reason.. sprint/lg do not want you going back at all. this is somewhat odd that its been updated 2 versions.. as none of the other g4's (besides tmobile usa g4) are at "v2".. everyone else in usa seems to have stayed at "v1" despite multiple updates.
tl;dr
if you flash this.. then try flashing a downgraded bootloader or zv4/zv5 tot.. you will brick.

They're doing this because Factory Reset Protection only works if you can't go back to a version that doesn't support it. Easiest way to handle that? Blow a Qfuse (or increment the counter as LG and Samsung seem to be using it.)

Just a quick question: FRP is that the security feature Google pushed so if one were to do a hardware factory reset the phone asks for your Google account before completing first boot after reset? Or is it the anti-rollback? Thanks.

FRP is the google security feature to protect factory resets.
but there is ALSO anti-rollback being used and ZV6 raises the bootloader versioning +1 from ZV5... so the first time a ZV6 bootloader boots.. from that point on.. you can never go lower than ZV6 again. Without bricking anyway.

Cant download update
When I click the link to download LS991_ZV5-ZV6_OTA_Update.zip I get a forbidden 403 error

Can someone please explain exactly what TOT means? I have been searching all over and can't find the meaning. Also, is there any way to flash to ZV6 and not update the bootloader so that ZV5 can be reinstalled if needed?

UPDATE i can miraculously get back into DL Mode and i tried again. This time the process took over 500 seconds only to say it failed again while doing an FBOOT CHECK and stays on the blue factory reset status screen with the number 2 in the center. I don't know what to dooooo ;w;

The TOT method resets the phone to stock - you will lose all data. Use this thread http://forum.xda-developers.com/sprint-g4/development/stock-sytem-image-files-zv5-zv6-t3205640 to restore the stock ZV5 image without losing data. You can then follow the same thread to sideload ZV6 and eventually flash the rooted ZV6 image with no loss of data. Make sure you always have the base image file saved to your internal (NOT sd card) storage.

We have no way at this time to keep any part of ZV5 and mix with ZV6. TOT is a method of restoring the factory partitions back on your phone using the .tot files / extensions.
The tot file extension is related to the Google Android devices developed by LG and used for its firmware update files

Boot loop problem

I previously had the LS991ZV5 update but I wanted to update. I was rooted so I did the full unroot in SuperSU and when I reset my phone, it was stuck. I went to install a firmware version. I accidentally installed the US Cellular firmware. I have tried all the threads I know of. I tried to edit build.prop to "trick" LG Flash Tool into thinking it was a Sprint model(which it is but the firmware wasn't.), however I messed up and now am stuck on the LG logo. This is my only phone. Is there anything I can do?

That's not how to unroot.
You have to restore the ZV5 image you backed up. You did make a backup right?
You can try to restore a ZV5 image (they are available for folks that didn't make one or lost it) or use the TOT process to restore it.
Look in the thread for TOT, Images, ZV5 ZV6 in developer forum. Everything you need is there.
Your phone should be recoverable.
Since you are still on ZV5 only use the ZV5 stuff until you successfully apply the ZV5 to ZV6 OTA Update.

Well right now, I'm on the US991 firmware not the Sprint one so I'm not on ZV5 I don't think. I also can't get past the LG logo. I have the tot but I kept getting errors and I checked the LG Flash Tool error log and it kept saying invalid tot file. Where is this ZV5 image though?

Flash TOT file and use Generic DLL
