I am planning to update to IZS v1 with the unlocked V30 u-boot. I have all the files but would also like to have my downgrade path back to Zeus 7.06 sorted. For that I need to be able to flash a locked V20 u-boot as far as I understand. Huexxx said in the IZS thread he would make a downgrade pack when he has time but it is not on his website yet. Is there a different way?
i usually keep a copy of the official LG v20g rom to flash back using smartflash tool.
get the official roms here:

i used this tool to covert KDZ to a patched bin/fls

I tried with v20q rom which is locked bootloader and it worked but impossible to root.
I tried with lot of v10 and other v20 unlocked and every time phone did not start: it blinked.
What can i do?Thank for you help.
I mean i can flash every locked bootloader firmware but none unlocked or i have a message "magic number does not coincide"

If you have p970 the V20Q firmware is unlocked and rootable just read NOOBY's HOW TO
Only V28 and V30 has got locked bootloader and both off them can be rooted
V20* and V10* supports CWM and is easily rootable.
Thank you but

v20q mean Gingerbread
Just download v20S patched .bin files and flash and no problems.
Lot of times, it save me.
From there, you can restore nandroid backup or you can flash any other Zeus or CM
don t work
[Thank you and merry christmas...
but nothing worked.The only issue should be to flash v10 bin and fls file NOT KDZ because lgconverteres is bad.
I looked in noob section and found no bin and fls v10 files (Kdz yes).Could you give me a link to download bin and kdz v10 files.
Thank you.
I'm looking to sell my O2X and I'm wondering what's the best way to return it to pure stock for the new owner. I'm currently on cm10 unlocked boot loader. I'm thinking nvflash v20q or something, but I was also wondering whether the LG update tool updates to ICS yet, as there have been full leaks for v30a/b... thanks
Smart flash the V30 A/B ICS..
You can use the AIO toolkit to smartflash a stock firmware:
AIO toolkit: http://forum.xda-developers.com/showthread.php?t=2020737
Firmware Downloads: http://lg-phone-firmware.com/index.php?id_mod=3
By flashing one of the KDZs it will bring it back to complete stock settings etc.
So seeing as to how the jellybean discussion thread exploded over the last few days it's been very hard to follow what's been going on. Also, I know I'm not the only one with this question so he goes.
1) How do I upgrade from regular stock ics to jellybean v20a? I have v10d and I have cwm installed+ root if that matters. My phone firmware is from Taiwan as well.
2) After installing jellybean, how do I unlock the bootloader and root my 4x?

Thanks! Followed your guide and am now on jellybean with root and unlocked bootloader!
Sent from my LG-P880 using xda app-developers app
I have CyanogenMod 11 made for the D415 LG L90, but I want to go back to stock because of screen problems and video problems. Can I use the flashing KDZ method with, say, KDZ 10e to go back to Stock Kitkat? Is there any extra steps or precautions while flashing from Cyanogen to Stock? I do not have an SD card, so I cannot flash a ROM through recovery.
Check this thread to offline flash kdz, this one for KK, and this one for lollipop

I know how to flash an offline KDZ, but is it possible to revert back to stock (10c/10e KDZ) through this method without bricking my device?
I encountered many problems as a beginner to install a custom ROM on my LG L90 D410 v20c Europe, because struggled to receive support, I posted on dozen of posts and never received any answer, since most of the developers have probably abandoned this phone.
So I post below what I did and worked for me. This doesn't mean it will work for you and I assume no responsibility.
PLEASE, USE THIS TUTORIAL AT YOUR OWN RISK, IF SOMETHING WENT WRONG ME OR XDA WILL NOT RESPONSIBLE FOR YOUR LOSS. Always do backups before of every operation if you are unsure of the outcome

I had my phone in a rooted state, with this guide
Then I couldn't find any unlocked aboot for v20c. Some were saying it was safe to use aboot file for 20b or 20s, but some were saying it was risky and if it did work, I would have lost my imei. I eventually also found an aboot for v20c from a russian website.
But in the end I decided to be safe and restore a previous stock version where there was a verified couple of KDZ and aboot. I choose version 10d.
I downloaded the file KDZ of the stock OS from this link, that looks to be from the LG website itself
http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=FW682806432109876543213/D41010d_00.kdz
and followed this guide to restore stock 10d
To download aboot file and successfully unlocking bootloader I followed this guide
Earlier I've tried also this guide and it DIDN'T work for me. It entered in a boot loop that I solved but then it couldn't install any recovery. It might work for you, but it didn't for me.
With the previous working guide I installed the old version of twrp, then restarted, installed the official APP of tpwr and from there I upgraded to the latest version.
I restarted in recovery and backup up my partitions, imei, etc.
At this point the most difficult part is done, and now you just have to follow the standard procedure to install a custom rom and gapps, downloading the versions of your choice in the SD, restarting in recovery mode and installing.
Here more details
I hope it will help other beginners in the same situation as me.
Unfortunately I can't provide support on anything since I'm a beginner myself.
