Secure Booting Error! Cause: Boot certification verify.

Hello there,
I updated my LG P700 to the v20c 4.1.2 JB version. After that, I couldn't find a wayu to root it, but found Framaroot app and succeeded with it. I got a little cocky how easy it was and downloaded ROM Manager. From it, I chose the CWM installation option and the window said it was a success. However, when I clicked to reboot into the recovery, only this little error appeared - "Secure Booting Error! Cause: Boot certification verify." in the left uper corner of the screen. Nothing worked, so I took out the battery and after turning the phone on, I noticed that all the internal memory got factory reseted or something like that and it is just a blank fresh android - all data was lost.
Long story short: flashing recovery from ROM Manager caused the wipe of the memory.
What happened?

[UPDATE] It could be caused by not unlocking the bootloader. I assumed that ROM Manager checks these things or flashes them with the recovery.
If that's the case (pls tell me) then I should unlock the bootloader. Maybe with this - http://forum.xda-developers.com/showthread.php?t=2197429 Does it work with v20c 4.1.2 android on my LG L7?

yes, the bootloader is locked, you need to unlock

Thanks, now I'm at least on to something. Does the method from the link works on v20c 4.1.2. version?

it doesn`t matter if you have ICS or JB, it must work

I tried unlocking the bootloader with the Flash_Bootloader.bat file, but the error windows flashes only for a split second. I barely caught it and attached the screenshot of it saying "the system cannot find the path specified". What should I do now?
Phone connected in pc software mode, debuggin is on.
[Update] I moved the CWM folder directly to the local disk C and it worked, but didn't reboot the phone. I had to unplug it and then turn on. How to check if my bootloader is unlocked? I don't want any more fails with flashing the recovery ;/

you were needed to write adb reboot to rebbot your phone after, and the only way to chech the bootlaoder is to go on download mode or recovery

Everything is working, just rebooted into Recovery from the rom manager. By the way, how does this adb work? Do I have to run the .exe file after the .bin ?

Enabling Root and Installing TWRP on F8132 Xperiam X Performance

The instructions are updated as of 11-20-17. Win7 only cause Win10 sucks and uses powershell and the fastboot commands don't work in powershell.
These are the proper files and procedures for installing Root, the latest Kernel, the best Superuser version and TWRP.
This is for NOUGAT 7.1.1. (and possibly beyond) There is a special procedeur to make flashtool work with the latest firmwares for Nougat ..
Before you Root and install TWRP you need to go back to my link and unlock bootloader..
You also need to download and install Android Studio Software and install it. Back to this portion of the install later.
You also need a special kernel to allow things on the phone to keep working.
This will work only for Nougat firmware.
You will need to download Boot img, TWRP img, SuperSu
Save TWRP and boot img files to the Android Platform folder in your PC here C:\Users\enter the current pc users log in name here\AppData\Local\Android\sdk\platform-tools . Save the Kernel zip and SUperSU zip file to an SD card and put the card inside your phone to access it through TWRP later in the process. Keep in mind that the Kernel may be updated. Check for updates herel here. Do a "date last modified" list of the files on that page by clicking on the grid view box on the upper right portion of the screen just under the "sign in" button. This helps you see what files have been updated in most recent order.
You will need to download the special Flashtool file here Install it.
Download the .jar patch file that makes the software version updated to the latest 9.23.2 and place it in this location C:\flashtools.
Now, download the special .fsc file and paste it in C:\Users"current user that is logged in"\.flashTool\devices\F81XX. Without this file you will not beable to update the device to nougat.
Goto C:\Flashtool\drivers and click on this file which was installed during the Flashtool installation.
Check off these boxes to install the drivers for the device you will be rooting. "Flash Boot Drivers, Flash Mode Drivers"
Now download and install these special ADB drivers to allow it to perform the Firmware update. Without it you wont beable to install the FTF file.
Open Sony Flash tool. Click on XI button. A window open. Click on Xperia Performance and then a small menu open under that. Choose F8132 ( i choose dual for my device)
If you can not get the newest firmware to show up for your device.( mine is 41.2.A.7.8 aka Nougat 7.1.1) then you can download it here Close Sony Flashtool.
Copy this FTF file and place it in folder C:\Users"The user you are currently logged into your pc with"\.flashTool\firmwares. Open Sony flash tool. Click on lightning bolt. Choose Flash mode in the small popup box. Window opens and shows your formware in the "firmwares" box. Click on plus symbol to the left of that firmware and it opens to the bottom to show the device model ( mine is F8132)/ Click on that plus symbol to the left of the model number to show the location of your firmware origination. Click on plus symbol and it then shows the firmware number 41.2.A.7.8. Click on the firmware and the entire window will populate a bunch of new options. If you want to wipe everythign on your phone then you need to check off the boxes "SSD and UserData" in the "wipe" box. Leave everythign else unchecked. Click the flash button at the bottom and it will start to prepare the files for installation onto yout device.
A window pops up that tells you to turn off your phone.
Turn your phone off. After its turned off, hold the volume down button while plugging the phone into your pc to get into fastboot mode. Your computer should be looking for the correct drivers to allow the device to work in this Flashboot mode. Once the flashing is done just close the flashtool. Turn your phone on. Go into settings and scroll down to "about phone then click on "build number" about 7 times. You will get a new optioon back in settings menu called "developer option". Click on that tabturn on "usb debugging" and turn off "verify apps over usb". Turn off phone.
Hold volum button UP this time while plugging phone back into pc.
Now go back to the folder C:\Users" name of user that is logged into the pc"\AppData\Local\Android\Sdk\platform-tools. You will open a cmd prompt in this folder by holding down your right mouse button and click on the shift key then release the mouse button. This will open a pop up window where you can choose to " open command window here" when the cmd window opens, copy and paste this "fastboot devices" press enter button, your computer should respond with this ......CB512A697c fastboot.......This lets you know that your phone is in the correct mode and ready to be programmed.
Now you will install the boot img by copy and pasting this in cmd line "fastboot flash boot boot.img" The PC should tell you OKAY with some other irrelevant info.
Now you will install the twrp img by copy and pasting this in cmd line "fastboot flash recovery TWRP-3.0.3-0-dora.img" The PC should tell you OKAY with some other irrelevant info.
Now you will install Kernel, and SuperSU. Turn on phone while pushing power button holding volume down button for about 5 secnds then release the bottom volum button then after 5 seconds release the power button to initiate TWRP.
Swipe to allow modifications then choose "Install" to install the zip files. Navigate to the SD card that has the kernel and SU zip files. Click on them to install. Reboot. TWRP might ask if you want to install the TWRP app before the phone starts to reboot. Just say no. After that, a few seconds later, the device reboots and then the Phone might go throw optimization process which takes some time. You will notice the counting of optimized files. Be patient.
When phone is booted and running, you might have to reinstall SuperSU via the Operating system as a APK like you would a normal app just to get root going. No big deal.
A caution...
When doing a backup with Twrp you should only backup System and Data
When doing a full restore, wipe only System, Data and the cache files. Do not ever delete your SDcard with the backups on it.
THIS IS THE VERY LAST UPDATE FOR ROOTING THE X Performance. IT IS NOUGAT 7.1.1
FORGET ABOUT ROOTING OREO>> ITS NOT GOING TO HAPPEN. PLUS IT IS NOT A DECENT UPDATE TO BE HONEST> IT JUST CHANGES A BUNCH OF MENUS AROUND AND LOCKS DOWN YOUR PHONE MORE>

Please do not upload my kernel to other hostings!
Official website for my kernel is
https://kernel.andro.plus/tone.html

So, if I was to relock my bootloader after installing TWRP and rooting, what would happen? Would TWRP go away? I'd like to let the phone OTA update to nougat, and you can't do that with an unlocked bootloader....

your phone will soft brick..or rather bootloop..if you're still on MM,do a nandroid backup..& here's what you do:
-relock phone using Flashtool.
-repair device using Xperia Companion(it will update automatically to Nougat).
-unlock phone again using Flashtool.
-install AndroPlus Kernel through command prompt(or you can also use Flashtool to do it.however you prefer).
-install TWRP recovery..you're all set!
P.S.
on steps i said(this is optional),you may not turn on your device along the process..that's what i do & i find it easier that way..goodluck!

I did try that - although, I set it up with a pin rather than a password. It didn't accept my pin when asking for the password.
Now I have a phone with a locked bootloader, running nougat, and I set it up with a password. I wonder if that password you use on the lock screen is the same password that Android is asking for when I unlock my bootloader?
I also could not seem to get the phone to boot into recovery after rebooting when I got the password screen. So weird....

So if unlocking the boot loader wipes data, how can android ask for my password when I reboot? I am a little mystified at how this is supposed to work Rooting Marshmellow was easier than Nougat....

true!MM was easier but Nougat is a bit complicated..however,you could still make changes on Nougat when phone is rooted.anyway,try again from the very beginning then this time after fixing phone using Xperia Companion,do the steps i mentioned..i myself couldn't figure out how it's asking for any password at first.AndroPlus also mentioned it before but didn't explain further.but it's alright coz i got it working now.

I think my issue with the unknowable password after unlocking the bootloader on Nougat could have been fixed by wiping data+dalvik cache. I was having issues with the camera under nougat so I flagged trying to get it going and flashed MarshMellow. Once that was done, I got the bloody password prompt again, so I wiped data + cache and it booted correctly.
Anyway, gonna ignore Nougat until fastboot supports nougat

Issues with passwords kept / unknown and blocked are due to the fact the security portion is stored
next to the data partition area, in what we call the footer, and that area was wrong for you.
By wiping data completely (most reliably, a factory reset which will format the data partition),
the footer is also erased instead of simply deleting the files like a Wipe would do.

lost system?
I got as far as getting boot.img and twrp.img in my phone, and then appeared to lose my system since it stuck on the Sony logo and wouldn't boot into the system despite several tries. Idiot that I am, I panicked and come onto the forum to post a plead for help. I've managed to get my system back on now and feel very foolish, so just editing the post to remove the request for help. Thank you so much for the guide, very greatly appreciated! Looking forward to upgrading to Nougat.

Will this guide work with Nougat? I have a F8132 with 39.2.A.0.327

It works if you get updated files. I struggled a bit before I finally extracted the boot.img from the AndroPlusKernel for my version which I flashed in fastboot and flashed the kernel and supersu in twrp. I think that's what did it. I was so eager to root that I missed that I was using MM-files at first. :silly:

I ended up finding a way to downgrade to marshmallow following some instructions from from @sdugoten

The instructions are updated.. With proper files for the latest and greatest kernel and SuperSU and TWRP. NOUGAT Only .. Will not work for any other OS versions

AS flashtool does not work for 7.1.1 how to proceed to install nougat 7.1.1 and enable root and install twrp?

Phones in a bit of a state

Hey guys,
Yesterday I tried, after a few months of not modding my phone, to update my recovery as i was running a very old version of TWRP. Long story short I did something wrong somewhere and my phone has ended up in a bit of a weird state.
At the moment the OS is BlissRom, however it fails to boot. The loading screen runs very slowly and never actually boots the OS. The current recovery is the stock recovery.
The thing that is giving me an issue is the fact that somehow the bootloader has locked, so I am unable to flash a new OS onto my phone. I'm not able to flash anything onto my phone as it throws an error telling me the phone is locked.
Overall I aren't able to boot into the OS, however I have access to the stock recovery and fastboot. Unfortunately it looks as though the bootloader has locked some how.
Any ideas how I can fix this, or have I completely messed my phone up?
Thanks in advance.

Hi
U said u were running twrp before which means u have unlocked bootloader and flash roms already.
How did u end up with stock recovery?
Also is it phone being detected bycur PC?
Sent from my ONE A2005 using Tapatalk

I believe it was a result of running the QualComm restoration tool. I ran this and it didn't look as though it did anything however after i rebooted into recovery I found it was stock.
I'm not sure if using this tool also re locked the bootloader however as it appears to be locked and I cant flash anything in fastboot mode.

Indeed I have, I get an error saying "phone is locked".
I think the resolution will be running the restoration tool fully but i cant seem to get it to do anything. It just sits there with no progress bars appearing.
Have you ever had any experience with this tool?

No I never used recovery tools.
Can u at any point let's say u boot into recovery and connect the device to PC, will it detected the internal storage?
Sent from my ONE A2005 using Tapatalk

Unfortunately not, if I boot the OS it gets stuck at the loading animation, it isn't a bootloop oddly enough.
Booting in recovery the PC doesn't detect the internal storage, however if I choose "Update from USB" I can see that ADB detects my phone in sideload mode.
Much like in fastboot mode I can see my PC detects my phone in fastboot mode.
I do have some OS zips on the internal storage which I have tried flashing in stock recovery, however these always result in "Install failed" errors.

Dude i think you have to use recovery tool now
Here is the link first read carefully https://forums.oneplus.net/threads/...ck-guide-for-a-hard-bricked-oneplus-2.347607/

Thanks for the link buddy.
I've gone through this thread, I think the issue preventing this from working for me is the fact that although I have installed the relevant drivers, when I plug my phone into my PC the drivers assigned to it are "Android Bootloader Interface". When I try to target another driver, using the Update driver functionality it just refuses to change, saying the driver already assigned is the newer one.
Any ideas how I can get around this? I know ideally it should appear as Qualcomm 9008. I've tried all the methods in the "How to Make the device show as Qualcomm 9008" section without any success.

Here's what to do...
U will need to sideload the stock rom which can be downloaded from here: https://s3.amazonaws.com/oxygenos.o...4_OTA_020_all_1608262242_44a55e674a2b4bf6.zip
-Place the zip in ur adb folder and rename it to update.zip.
-Connect the Oneplus2 to the PC with USB cable and open a command prompt or terminal on your PC. To do this open the ADB folder press shift + right click and click on open command here.
-Reboot to recovery and select install from usb.
-Flash the OxygenOS on OnePlus 2 by typing:
adb sideload update.zip
-Now the update will start and this will take some time.
Hope it helped[emoji106]

Hey dude, thanks for the help! So I went through these steps and it actually appeared to sideload and update properly.
However now it looks as though my phone is stuck at the one+ logo when I go to boot the OS.

My Redmi 2 stuck at mi logo after rooting by super su app.

please help me friends.....
i have redmi 2 and its model no. is 2014818.i rooted my phone by zip file throug updater app.after installation super su app installed automatically.then i opened super su app and it prompts to select continue with normal recovery or twrp/cwm custom recovery.by mistake selected second option which is twrp/cwm custom recovery.then clicked continue.after that my phone booted and that after stucked at mi logo.
my phone is not going to recovery mode.it is stucked at mi logo.
But it is going into fastboot mode properly.also i flashed latest rom by fastboot method and it shows success result in mi flash tool.but after booting it agian stucked at mi logo.i also tried to flash by command prompt by using adb and fastboot tools.all commands i give gets executed properly but the problem is not solved
i went to Mi service center.he told me that "i will do some software update.after some time he came up and said that the phone is taking much time and stucked at mi logo.
then he assumed and told me that ,there is an issue in motherboard i.e. the motherboard is currputed.
but in my perspective i dont think so, because all the fastboot cammands and functions are woring properly.
please help me in this situation and suggest me that whether it is software issue or hardware, and also about the chances of resuming to life of my phone.

you should try to flash the firmware again but don't forget to select clean_all while flashing from mi flash tool. if your phone doesn't revives then maybe it's hardware issue.
and yes also try to install custom recovery and custom os after flashing firmware maybe your phone gets a new life.

U can't flash stock ROM by fastboot r8?
Have u tried to flash T.W.R.P by fastboot by using mi flash tool(try to use latest version of mi flash too).
And direction is here.If that succed then all is good.

i tried to flash TWRP and CWM recovery By Adb and fatboot method using commands (command prompt method) amd on giving commands all executed properly but not resulted.
From now phone is not going into fastboot mode also and not booting on pressing power button.
On connecting to pc the notification message appears and says "unrecognizable device and device may be malfunctioned".sometimes it is detected as Qualcomm Device on connecting.

In that case your device is hard bricked. You need professional help.
But check if your device is listed or not in device manager if it shows an exclamation mark try to update the drivers and though your device doesn't boots into fast boot mi-flash would probably detect your phone and than flash hope it would recover your device up-to certain extent.

I only understand your problem why because I too same thing as you did.

i went to Mi service center.he told me that "i will do some software update.after some time he came up and said that the phone is taking much time and stucked at mi logo.
then he assumed and told me that ,there is an issue in motherboard i.e. the motherboard is currputed.
but in my perspective i dont think so, because all the fastboot cammands and functions are woring properly.
please help me in this situation and suggest me that whether it is software issue or hardware, and also about the chances of resuming to life of my phone.

Simply flash twrp recovery n your phone through adb drivers or contact me. I can't give you video tutorial because I don't want you make that mistake again. my mail id: [email protected]

Alrighty I think praveen66542 is not wrong.
I have actually a redmi 2 and I had exactly the same problem a year ago; I've tried all the methods but it didn't work
So i've do is :
I installed Android SDK + ADB Drivers
I Turned my phone into fastboot mode
And I wiped all data from ADB But if you don't want to loose your data you can always do a backup from ADB and then wipe device's data
I think that's the one and only working solution.

Bootloader unlock failed. ID: Bad Key?

I just got my Moto G5 Plus today, and ran Motorola's official Bootloader unlock guide.
Upon starting up, I am now receiving an error that says "Your device has been unlocked and can't be trusted. ID: bad key"
I confirmed multiple times that I provided the correct unlock_data and entered the correct unique key provided.
Because of this I cannot flash TWRP.
"(bootloader) Image not signed or corrupt"
What can I do here? Is there a way to re-do the unlock?
Do I have to flash stock back to the phone? I cannot seem to find any guide on how to perform that properly.

Are you sure TWRP didn't flash because it gave me that same generic error (because it's no longer stock recovery) but it had installed fine. Did you try selecting 'Recovery Mode' in the bootloader and see if it loads? Hopefully you're following the rooting tutorial in this forum because you need to follow it closely to correctly gain root.
That 'bad key' message on startup is normal after unlocking and can be removed by flashing another 'logo.bin' as shown in this video, so actually seeing it shows that you probably did unlock successfuly.

Correct, as everyone has stated, this is normal for a bootloader unlocked device. You can flash a logo.bin to make your boot up look better

Were you able to fix this? I have a similar problem.

I am also having this problem. Everyone saying this is normal, is wrong.

The "normal" message once it's bootloader unlocked is "Your device is unlocked and can't be trusted...Your device will boot in 5 seconds." - it doesn't say anything about a "key".
EDIT: oh, and where his said "ID: bad key" mine says "ID: n/a"

Yes I found out my problem was that I was using a later version of twrp and you have to first use an initial build on one of the rooting threads.

I'm having the same issue. Got the unlock key from Motorola and successfully unlocked bootloader from CMD. The phone then booted up as if it were new. I access the recovery mode and get "device has been unlocked and can't be trusted". No other option. I've tried manually and through CMD. I've downloaded all necessary files including the kernel, ADB, fastboot and twrp. Nothing works. Phone operates as if I factory reset it.

I just rooted my Moto G5s plus last night...here were my steps:
1.) Do the Motorola unlock B.S.
I had fastboot.exe and adb.exe from the Android SDK installed
I did find that I had to unlock my phone or adb could not see it
2.) After unlocking, you get the "untrusted phone" screen
3.) Use fastboot to flash a new boot image: fastboot flash boot logo.bin (I built a logo with MotoBootLogoMaker), this gets rid of the untrusted screen
4.) I do have the "bad key" message show up during boot, but it hasn't impacted anything...it is in white, my boot logo is in white, so you don't see it.
5.) Get a copy of SuperSU.zip on your sdcard and load into your device
6.) I installed TWRP (twrp-3.11-sanders.img) to the recovery partition, but that caused an issue: fastboot flash recovery twrp-3.11-sanders.img)
* Recovery wouldn't boot after this, so I successfully booted the image directly with: fastboot boot twrp-3.11-sanders.img
6.) TWRP successfully loaded....
7.) Use TWRP to install SuperSU.zip (this roots the device)
* I wiped the dalvik cache, but that hung and I ended up powering off...but fortunately it didn't brick the device
8.) After reboot, I logged in with "adb shell" and did an "su" to prove I was rooted.
9.) I replaced bootanimation.zip with one more to my liking than the Lenovo one (/system/media/bootanimation.zip I think was the location)
That was it...
