Hi everyone
Nearly three years ago I made a backup of my apps and data using LG PC Suite. At that moment I think my phone was already running JB 4.1.2, v20a or v20d idk. Now all the files are in a folder and have extensions .tar.enc, .tar.gz.enc, .brinfo and there is some start_restore file.
Between back then and now, I have made an attempt to root my phone using the Framaroot tool, and it succeeded. This morning I tried to restore the backup to my phone using LG PC Suite (probably a more recent version). After rebooting, my phone was displaying something like this:
Code:
[4180] secure booting error!
[4190] problem: boot certifiation verify
:crying:
I've had a thorough look through the fora the whole morning and half of the afternoon and still can't figure out why it gets stuck there. The restore operation doesn't succeed in any case.
In the mean time I've flashed a TWRP-3.0.2.0 recovery on top of the stock recovery. At least I get the recovery mode working, but I still wonder if it was the most clever action to get to a successful recovery of my backup...
Hence, I am still nowhere where I want to be. My questions for you guys:
Does any of you know of a way to restore the data in the backup without needing the LG P700 phone, e.g. using a virtual LG HW emulator?
If not, does any of you have a copy of the stock recovery mode of the LG P700? (yes, indeed, the one that looks ugly) Maybe using that I could bring the phone back in a near-original state and the backup restore would complete instead of getting stuck like now
Thanks in advance for your help, it will be much appreciated!!! :good: :victory:
PS: As soon as I get through this, I'll consider making a ROM build based on Android Oreo (8.1) Go edition. The specs give this phone a second chance to live on!

Hello everyone I need some help with my G2 its the rogers D803, First off I'm kinda a noob when it comes to flashing roms, this is my third G2 I've owned, i bought it off kijiji and its been nothing but trouble, my LTE wouldn't work and I couldn't update it to 4.4, The ota wouldn't work cause the device was not resisted. I tried to update with the LG support tool, when i would connect the device it would say update found then all of a sudden it would say your device is up to date. So i decided I would root it and flash a custom rom. I used TWRP a flashed Mahdi Rom and it worked great. Now here is where I messed up, I decided to try another rom, went into recovery and did my wipe but i accidentally wiped the system along with all the roms and zips I had on the internal storage. now its stuck i n a boot loop, I'm still able to get into twrp and also can get into download mode. my problem is I'm unable to mount the device to get my roms or even my backup folder back onto the device. when i plug the phone in i cant get the drivers to install , ive tried using ADB but my device doesn't show up on there. it does show up on the lg support tool when i put it into download mode. If anyone can help me out it would be much much appreciated. sorry for the wall of text but I'm trying to give as much details as possible.

It was getting stuck on the Lg logo but i was still able to boot into twrp. but good news I just figured it out. I downloaded Koush universal adb driver and was able to sideload a new rom.
Hello all,
Today I read a lot of posts here about rooting my phone because I was done with the stock UI.
I went for it and now I think I made a mistake, I would like your help. I read some similair posts, but I cant find a true solution for my problem.
My goal is to run CM 11, I have a stock LG 802 config with 4.2.2.
My steps were as followed:
- I used towelroot v3 wich was succesful
- I installed and ran D802 autorec (wich i guess was a bad idea). I got to recovery mode and I wanted to back up first.
- I made a back up of boot and system
- After the back up, I had to reboot
- NOW its stuck in a boot sequence to nothing. Just a light green and blue. I get the logo and I can get in the stock recovery it seems. Should I reset to factory settings?? Is that data still present?
I hope I can go from there, but after my major fail Im afraid to try it.
Thanks a lot in advance!
Update
I can get into download mode and LG Support Tool finds a phone, but the specs do not match and the update states that there is not any update available, wich there is.
When I get into recovery mode I can get into TWRP and I should be able to continu the process with flashing and wiping. The CM mod and Gapps are already on the internal memory. But I am really afraid.
For the record I did not flash or wipe anything yet, except for running Autorec and rebooting after prompt.
The real question for me is (I guess), is Autorec really unsupported with 4.2.2?
I would like to go on with the process, but I also would like to go back stock if needed in the future (hence the recovery back up I made with TWRP before the bootloop.)
Thanks again for any help what so ever
Hello! I was able to restore to stock my KK LG G2 D800 from KK to JB last week using the TOT method. After I restored to stock I went ahead and took all of the AT&T OTA's until I was running stock LP. After I got stock LP I was able to root and install TWRP.
Last night - stock LP was running sluggish (go figure) so I decided to go ahead and do a factory wipe in TWRP. However, out of habit - I went into advanced and wiped everything but the SD card. I went to reboot and...now I have no system installed on the phone.
For whatever reason - I cannot get the phone to boot into recovery. I've tried the physical button presses a million times in a million different configurations but it just won't boot into recovery no matter what I do.
I plugged it into the computer through USB and the phone is being recognized but I cannot get ADB to find the device so I can issue commands.
I am able to get to the phone into download mode no problem - just not recovery.
I tried to go back to stock using the TOT method again - and LG Flashtools fails giving me a download error before it starts.
Any help and/or advice would be greatly appreciated. I took it to AT&T Device Support Center and the guy told me LG hasn't given them any flash tools - could just be because the phone is rooted.
You state that you tried the TOT method using LG Flash tools, so I assume that you followed all the little nuances of that method (going into device manager and setting correct COM port, removing the cable one time and reconnecting), etc. I don't remember all the steps with 100% accuracy, but any guide (either xda post or you tube video) contains all of them. I did the same thing as you a (wipe system) a while back, and there was no way to get back into recovery. I had to do the entire TOT procedure.... Good luck

Thank you for your reply. Yes, sir. I tried the different .dll's and changed the port to 41 and everything. I did just fix the issue - I was able to FINALLY get into recovery (gotta make sure the phone is COMPLETELY OFF!!!! - whoops). Once in recovery I was able to download Grola or Simple ROM and flash that through TWRP. Everything booted up perfectly and I am back on Lollipop. Once some D800 LP ROMs start popping up - this won't be an issue anymore.
Good Day everyone
I am in desperate need for some help please, i managed to brick my LG G2, and need help unbricking it
I have the D802 International model.
The story so far, it had Cloudy G2 2.1 Rom on, wanted to update it to, Cloudy G2 3.3 , followed the guide on Blogspot, when, you search for "kevin with tech cloudy G2 3.3" on Google
Wiped the partitions via TWRP 2.7, as stated in the video (everything except internal storage), and then installed the KK-D802 bootloader.
After i rebooted, my G2 did not come boot again, it will go on with the boot logo and the words: "Boot certification verify" Secure booting error. will appear for about 2 seconds then just goes black.
Whenever i try to plug in via USB cable, it will detect multiple new drives in windows and accept me to "Do you want to format". in the device manager i can see device being detected as "QHSUSB_BULK"
My phone is rooted as well.
Some sites recommend using a linux way, but i have been through countless forums, and not sure which way is the right
Please please i need some help unbricking it, and willing to donate to the successful user advice / tutorial of unbricking it.
Thanks for reading and in advance.

Had the exact same issue, I believe it's caused by corrupting the internal memory (multiple causes for this).
Don't freak just follow http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 (there's a video guide at the bottom, but it's pretty straight forward).
After that follow http://forum.xda-developers.com/showthread.php?t=2432476 to get it back to stock and work from there.
Good Day everyone
Thanks for all the advice and help, wanted to update the thread to solved, but things went a bit hectic at work during the week.
Anyways managed to get my phone working again, and restored to original state(thank God).
Basically followed a guide i found on Youtube, used the LG Flash Tool 2014 to flash back to Kit Kat stock, and then from there i rooted and used Auto_rec.
Found a guide on Reddit for Cloudy 2.2 install, flashed correct KK-Bootloader, and restored my Nandroid backup (which strangely at first did not work when restored via TWRP on stock Kit Kat, got the same Secure boot error)
Restored only data and system (everything except the boot) and my phone was back to it's original state.
Hope this helps anyone in the same situation.
PS: I was stuck in some boot loops, so had to format my internal memory as well.
Peace
My tmobile LG k20 plus phone has a boot loop and will not start, this happened when I copied a file to the main directory of my phone, instead of merging the files it deleted the system folder, I tried to fix it by reinstalling twrp and it worked, after flashed twrp I installed a fresh SuperSU ROM and when I did the boot loop did not go away and in addition to this my computer will no longer find my phone through ADB or fastboot, if you can help I will be amazed and quite happy, I'm new here so any help is appreciated

did u ever get it figured out? i am in the same boat grr
I found a program called lgup which was able to fix the phone, it's capable of flashing a new rom onto a soft bricked phone. Sadly I don't recall any specifics but on a quick search for "lgup lg k20 plus" you should be able to find what you're looking for with relative ease. Also, you may want to consider making your own thread on the future... It has been 3 years

Yeah. Sorry for the late reply given you guys found the fix by now, but yes, generally with the sort of severe mishaps from editing or accidental deletion of certain system files or directories, sometimes a dirty flash or even a totally clean flash after performing data ave system partition wipes, will just not fix or restore the device.
You would then need to do a complete stock image reflash either using LGUP or the official LG software recovery tool. If you know what you're doing, you could skip over reflashing stock in its entirety, if say you know the problem has only to do with a particular protected partition like modem, EFS, etc. But generally good practice to just recover all the stock partitions, refresh the device software to factory conditions, reflash your bootloader and recovery images, root STOCK or install custom ROM, so on and so forth.
If you're a frequently curious tinkerer, making backups will be crucial to your sanity.
