So this is the first phone I rooted and pretty sure the bootloader was unlocked I installed TWRP but I know for sure I rooted the device and I am assuming the bootloader was unlocked due to my phone bricking after OTA from Sprint. The update was installing and when the phone tried to reboot I got the following error. Secure booting Error! Cause boot certification verify. I am able to get in download mode after trying a few times. My question is what should I try to do to fix my phone.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.

Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.

Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.
Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it
It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter
I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

If you need help with unlocking your phone contact Alejandrissimo he does Unlocks
I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?
Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps
Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

hello this is not working by me?i cant get into fasboot.if i shutdown the phone and the volume up and power the lg logo blinks 2 times and optimus g get on normali.
Important Information
To enter bootloader, hold volume UP and power.
why the hack doesnt work that?
its safe tu unlock bootloader with 0.5 freegee?
beacuse its says thaht i heave new locked security and if goes wrong my lg will be bricked werry well.
i wass trying to run freegee 0.5 version and in one row says this script is not for my device?
what to do?
i dont heave ATT device.
AFAIK you can't run the fastboot until you've unlocked the bootrom (e.g. with FreeGee).
Have you downloaded the latest version of FreeGee from google play?
What is the exact message you get?
hi
i downgraded the phone from 4.3 to to 4.1.1 using mobile odin but now the baseband is unknown and IMEI Null

what i did then looking for brick image to make phone up and then flash another one , i found my self in trouble unlocked phone became locked i lost everything on phone
baseband and IMEi is null and unknown ,
i bought the phone as unlocked sim phone and now nothing success with me
what i should do to fix this problem?
If you can get into download mode, flash a custom recovery to your phone and then flash an old cm11 ROM to see if you can get the phone booted.
which one to use

how to solve this
Has anyone successfully put a custom ROM on this device? I used to have an old Samsung S3 where I was able to put on CM and it was a piece of cake, but with this tablet I'm having issues with the bootloader being locked.
So far I've tried to install TWRP, CWM, and Philz custom recoveries. The problem seems to be with the versioning. Everything is customized for the v500. I was able to install Philz_Touch_recovery_V490.img which allowed me to boot into some sort of 'fastboot' recovery mode when before I would just get the message: "error boot certification verify" on start up. This fastboot mode isn't the Philz interface and it doesn't give me the option to back anything up or boot a ROM. It doesn't really give me any options except to restart, restart bootloader, or power off.
Were you on Lollipop or Marshmallow before you bricked it? (Which one?)
Lollipop.
The device is not bricked as I am still able to access the stock ROM. I just never was able to access my boot loader. I keep getting the error message "Error: boot certification verify" My carrier is US Cellular and they tend to lock a lot of features on their device. Is it possible they blocked boot loader access to be assholes?
BTW, my device is successfully rooted. (I checked with a root verify app.)
I'm looking into implementing the loki-master hack to unlock my boot loader and hopefully then Philz recovery will work as intended. (It is the only custom recover option that didn't give me an out-right failure message). This does seem to be an advanced developer tool requiring some code skills. Anybody have any tips for this Loki procedure?

I would doubt if you could still use the Loki method on a stock LG Lollipop ROM. For example, LG patched the Loki exploit on the VK810 LG G Pad 8.3 as of KitKat, and Lollipop on this device can't even boot the ROM using the old bootloader - it requires the Lollipop bootloader. In our case, the exploited bootloader can be temporarily reflashed to get into TWRP, but then we have to reflash the Lollipop bootloader to boot the ROM again.
sorry bring up old stuff
so i was able to root. have su i bcked up stock recovery and basicly any recover i flash i get the boot error but also gets fastboot.
ofcoarse ive tried most common commands and she wont reconize any of them.

Lg g pad f 8.0 v495
I rooted with kingroot apk but make sure you use kingroot version no higher than 4.5 . Because you are going to want to use SuperSume to replace kingroot as superuser it runs alot smoother. And for some reason any version higher than 4.5 of kingroot the supersume always freezez u. Hope this helps. If u get time pm have a question totally unrelated to the g pad but could use some help.
Howdy, Y'all! I have a buddy who has a Q7+ that bricked its self during an update. Powering up, the phone goes into fastboot mode. I have tried searching for the stock ROM for it, but all the download links I have found seem to be either expired or no longer working. This Q7+ is from Metro (by T-Mobile). We tried to unlock the boot loader to install a custom ROM but since LG no longer has their dev portal working, this was futile. We also tried with this reversed engineered MTK Tool but that also did not work as it did not pick up the phone. If someone could either help us to unlock the boot loader and get TWRP installed or get us the stock ROM, we would greatly appreciate the assistance. Thank you all so much!
