So i have my LG g4 h811 on what was 10h before I "unlegit" put it back to stock using TWRP and .zip. Now I have it in a constant state of "optimizing apps". I was going to place it on something else but was unsure if I would put it back to 10h, 10n, or v20p. I've searched enough and had no results. Any help would be greatly appreciated
If you are on 20i you must flash 20i or newer software. Anything older than 20i will brick your H811.
So I now flashed it to 20p and now a constant bootloop comes-up. I have had this phone for a whole year and I highly doubt it's the dreaded desolder issue, but i'm not sure. Why would it continue to bootloop? I thought that was supposed to fix it?
Did you use LGUP and flash a KDZ file?
That's the best way. Choose 'refurbish' in LGUP and don't forget to back up any data if you can.
Use the P kdz instead of Q if you wish.

Hi guys!
I noticed today that there were a system update for my optimus 2x.
But after it downloaded it said validating software package and returned an error stating that the package was invalid..
Has anyone else bumped into this problem? Is it because my phone is rooted?
It is otherwise stock.
Thank you so much for your help!

Okay.
So can i ask how do i unroot the phone using CWM?
I looked at this thread: http://forum.xda-developers.com/showthread.php?t=1021554&page=2
it talks about installing a recovery.zip using CWM, but will it unroot the phone or not?
Thanks!
The name says it all and it is sticky in dev section...

Hi and thanks for the answer!
you see, my phone is already rooted. I need to unroot it in order to get the latest update from LG installed on my phone.
The reason for this is that when i download the update OTA and try to install it, i get an error message stating that i have a invalid software package.
And the reason for this as i understand, is that the phone is rooted.
i have read the roll up thread you linked to, but it does not state anywhere how to unroot the phone. And thats what i need help to do
Use smartflash and put some older version on it, then update it to current version. It will be unrooted.
Thank you for the answer, will try that!
But im struggling a bit to find the older versions though. The links to them are either down or broken. I need the EUR version.
You can flash stock v20q via cwm. If you said that your phone is rooted, install cwm and then flash this stock v20q.
If you want to downgrade, then update using lg update tool, you need smartflash and some older firmware like Euro v10d.
You need to read and search, really, all is here on the site.
At least press the thanks button if my posts are helping you, it is right here.
Thank you for the reply.
I will flash with the v20q one you mentioned. Its the version im trying to upgrade to anyway, så this seems better instead of downgrading it to stock, then upgrading using OTA!
How can I revert my LG 2X back to stock? Currently running CM10 with the new bootloader. I have found multiple threads about this but I'm afraid to brick my phone because there all outdated.
Can someone provide me with a step-by-step guide thats more up-to-date?
Thanks very much.
Well you won't get that kind of guide, cuz only small part of users still using p990 (my guess) got back to stock, so all the guides are a bit outdated but shouldn't brick your device. Saying it short, use the old guides
Sent from my LG-P990
Easy method:
Use smartflash to install an old baseband like 20S. Then use LG update tool to flash the latest stock for your region. Alternate, use AIO tool to flash both baseband and stock. You will need to download .kdz file and extract it to fls and bin file in AIO tool prior to flashing. Fls are baseband and bin are the rom
Well because i can never leave things alone until i get what i want, i ended up soft bricking it again. I flashed the modem from 4.2.2 ATT to the D-FUSE Rom and somehow it wiped my backup and custom recovery, so i wasnt able to restore, or edit the build.prop because it was in a boot loop.
To get out of the boot loop and the cross Dl error this time, i edited the the tot file with HrHex editor to change the hardware ID. once you open the tot file just ctrl+f Find D950 and change it to whatever hardware your device is (just the first instance, no need to change the software version id), use the universal dll file to flash the edited tot.
Once it finished flashing the ATT 4.4.2 tot, i was able to root it with stumproot and install freedom flex recoveries on the stock KK 4.4.2 image.
I am going to attempt flashing the ATT 4.4.2 modems this time on top of the D-FUSE T-Mobile Rom.
If anyone knows the correct sequence of wiping/flashing to get my desired affect of T-Mobile Rom with ATT Modem working please let me.
Also, if these updates are annoying please let me know. I have yet to find a complete place that has all the fixes for these errors. My hope is this helps someone else messing around with these files and getting into trouble.
*******************************************************************************************************************************
I have it resolved, while in the DFUSE ROM, download ES File Explorer and edit the build.prop hardware id to match D950. Turn off phone and leave it off, get your flash tool ready with the tot file loaded and the D950 dll.
If you have already set your com to 41 for the USB port/phone then first hit the arrow for the flash tool to say ready, then put the phone in download mode, and it will start flashing the phone.
Has anyone ever tried to backup EFS and Modem from factory image, than flashing it over the DFUSE ROM?
********************************************************************************************************************
I have the ATT D950 (LG G Flex), i decided against the better judgement of the forum post to flash the DFUSE kit kat Tmobile Rom.
Now i cannot recover using any flash method, including using the D959 dll and the universal dll with the att tot's.
Would someone happen to have a ATT D950 Rom, so that i can flash over what i have now to change the hardware ID from D959 to D950 or does anyone have a sure way of me flashing the tot file with the current discrepancy.

I used the build.prop of D958.
flashed D95820a tot to LS995 and before that I backed up boot and modem from twrp in LS995ZV7.
then after flashing stock tot d958 i rooted, twrp, then restored the boot and modem backup.
NFC isnt working but everything else is.
I have the Verizon version of the phone.
I am having so much trouble reverting back from 39A to 27A through KDZ method. I've tried TOT method as well, but it isn't working under Windows 10.
I do not have learning disability. So, I have followed all the instructions on how to use KDZ and TOT.
Any advice?
Flashed last T-Mobile update (20q) from twrp on 20i (first 6.0.x stock roms), the camera is not working, since i got the phone on ebay has used with bubbling glass defect (outside screen zone), i did not tried the camera before. Do i need to flash the new bootstack since i used the roms only ?
Edit : Downgraded to 20P and everything is fine.

you should get 20q according to devs kernel has lots of updates.
i know thi happens when you use flashable zip and flash in twrp... or maybe the lg bridge. to fix this . you must update using LGUP and KDZ file.
NOTE dont downgrade to 20i or youll hard brick phone.. if you do say good bye to phone.
