[Q] LG G2 D802 Kitkat root problem

Hello,
I have LG G2 D802 brought from UAE. I accidentally upgraded to KitKat 4.2.2 after I brick my phone when trying to install trwp recovery in my 4.2.2 firmware. As I was eager to root it, I saw a method using IOroot25. It went very well and speruser and busybox are installed. But the recovery was horrible as it is not recognising my internal memory at all, when I tried to flash zip files it is not showing in the sd card and no option for back up also. So I tried to use the trwp manger, after that now when I tried to boot into recovery, only error message comes saying that " certificate error", Otherwise the phone is working very well. I tried to unroot using the flash tools, failed, also tried to downgrade firmwae to 4.2.2. using flash tools, failed. No neww rooting method also appering in any of the LG g2 forum. Kindly anybody can help me to solve this problem.
Thanking You

Downgrade worked for me twice. Just after downgrade, you must perform a factory reset.

Downgrade failed

Thanks for the reply,
I tried downgrade using the Xda thread. When I start upgrade, it goes to LG site and says you have the latest firmware, and it stops there. Can you please send me the details how you downgraded. Remember my 4.4.2 shows it is rooted, I tried to unroot using this thread thttp://lionking853.blogspot.ae/2013/10/how-to-root-and-unroot-lg-g2-all.html.
It also failed
So kindly help me
I want to downgrade urgently

No unroot will work. Only flash back to stock which was as replied above. Do not use the official lg tool. Use the one in the thread above.

Moto x play help!!

Hi could anyone help with flashing my phone.
After an attempt to upgrade to marshmallow my phone no longer read my sim so I attempted to flash back and now I am stuck in the fastboot menu.
Can any one send me links or a detailed guide on how to fix this please?

How did you attempt to upgrade, were you on Stock and took the OTA or did you flashed a MM Firmware?
What steps did you follow when you tried to downgrade?

Help, I cant flash marshmellow!

Hey, i cant flash my C432B524 rom in the stock recovery, can someone help me?
My current rom is, C432B188, im not rooted but my bootloader is unlocked.

Try out TWRP and flash the .zip with it

You cant flash a zip with the stock recovery.
Or were you trying to update via local update and an update.app? And where did you get the version that you tried to flash? Go read on this forum. Theres a search that might help you too.
Have a nice evening

I was trying to install the update.app file from stock recovery and it doesnt work :/

how i can reflash complete a ROM?

hi, i have a p9 lite model vns-l23 (latin america), in some time i flashed with vns-l23c605b120 ROM and all work ok, only have one bug (the mobile data icon)....
now i flash and older version of the same ROM and all was a mess so i try to flash again the l23c605b120 with the oficial method but its says that the ROM isnt compatible with my phone....
searching over the internet i found that i can extract the UPDATE.APP file then flash some part of the ROM with fastboot, so i did that, now i have l23c605b120 but some time i am having boot delays, i tried clearing my data and so.... but the issue persist, i cant reflash the firmware using huawei method because still say that the ROM isnt for my phone.
iany knows a way that i can use to flash the 100% of the ROM without any issues?? Thanks!

Try flashing it via TWRP...

I cant find the flasheable version of the ROM, do t know how convert It neither.... If this help i found this: (look the attachment)

how to come back to stock rom?

Hi, i've a p smart Fig-Lx1 with rescue rom installed (after brick) from figo folder , FRP and Bootloader unlocked, no root. When i try to install an update via ota, an error occurs. When i try to factory reset smartphone goes into erecovery and can't download any firmware. The only firmware that i can install is rescue firmware via command prompt. I want to install last firmware but i can't. can you help me?tnx. P.s. After installation of rescue rom , if i try to relock bootloader , i've a bootloop into erecovery and Twrp recovery.

Is bluetooth and everything working OK? Try upgrading through Huawei Firmware Downloader app.

i'll try to use this app... thank you for now

The firmware finder for Huawei is the way to go, that's how I reverted back to the stock rom after I bootlooped

Problem solved with firmware finder, thank you

I also wanted to go back to the stock rom so I flashed the stock recovery and downloaded a stock ROM image (mega.nz/#!qbRyCYiI!G-1ctQEUKj_2ksHS-rU-yWiF8YZyiYSllQBSBbHoC78).
I thought it's signed but when I relocked the bootloader it only showed the eRecovery so I had to unlock the bootloader again and now I can use the ROM and it receives the latest updates.
I want to lock the bootloader because the message before the booting is pretty annoying but I don't know if my ROM is signed or not. Is there a way to check it before relocking the bootloader? Can it be in signed state due to the official updates? Are the firmware finder updates signed?
