[Q] LG-V500 Secure booting error, boot to TWRP only. - G Pad 8.3 Q&A, Help & Troubleshooting

Stock ROM rooted. I think bootloader still locked.
Upon turning on lg-v500 there is a message in the corner
"Secure booting error
device unlocked so boot success"
and goes straight to TWRP
Cant restore backup - says successful but goes again to TWRP after reboot with same secure booting error message.
Tried this
Now, you have TWRP right?
Grab an external SD card and load a ROM onto it through the PC (for GPad)
Put SD in GPad, factory reset device.
Now go to install, external sd, locate ROM, Swipe to flash.
After flash wipe dalvik and cache then Boot to ROM.
No luck - result as above. boot to twrp and error message
Want to try this - but can not install usb drivers on 3 laptops, so no connection with lg pc suite
Download LG PC suite and install LG drivers to PC.
Plug LG GPad in PC
Run the LG Suite click Upgrade recovery.
Now it will download stock LG ROM and after download will flash automatically.
Will then reboot after flash.
Hopefully now is fixed.
If hangs at boot screen boot to stock recovery, (power off, power button + Volume down, when LG logo appears let go off all buttons, now press all three in. Will need two hands for it,)
Then get a factory reset prompt, click power button twice to perform a factory reset.
Any ideas, guides please?
That option helped
get the LG mobile support tool, power down the tablet completely (hold power for > 30 secs), hold the vol up and down buttons, and plug in the USB. This will put it in download mode then use the LG program to reset to stock

OTA Update Elephone P8000 stucks at Boot Logo

Hi there,
I just updated P8000 via OTA update and after downloading the Update, the phone restarted and stops at the elephone boot Logo (about 30 min )!!
I did 5 Restarts but every time it hangs at the boot logo...
In the past i did no other updates or flashing ROMS.. nothing!
When i press "Volume Up" and "Power" to Start, i get three Options:
Recovery Mode
Fastboot Mode
Normal Boot
Using Recovery Mode leads to: Symbol Android Robot with "No Order" (in german : "Kein Befehl")
Using Fastboot Mode leads to: Nothing (Recovery Menue stays)
Using Normal Boot leads to: restart and hanging at Elephone Boot Logo
So, I am running out of Options... any ideas?
Cheers, Albert
Same. I tried using the official instructions to flash the stock rom but the SP flash tool stops responding after download button is pressed

The Hardware of P8000 is pretty cool, but the Software is "§$§"%§""!$%
When you go to recovery mode and get the the android robot symbol. Press again Vol up + Power until you enter to recovery. Make a 3 wipe (data factory , cache and dalvink). Reboot and uninstall the El loader. Use another Loader instead of El Loader
i had the same problem. (in English NO COMMAND) I only flash Eragon ROM again. Sometimes you have to repeate.

After that everything goes according to instructions

Hi there, sorry for the revival !
But i got the same problem: OTA update, fail, P8000 blocked on boot screen.
I tried wipe data/factory reset + wipe cache -> nothing changed, still boot screen blocked...
Then, i tried to use flash tool, but, the phone isn't booting, so my pc isn't recognizing the phone..
I'm not even sure that I correctly installed the drivers..
Can i use flash tool even if the phone is blocked to boot screen?
I downloaded this ROM: stock-rom-elephone-p8000-20150907-android-5-1 (this is my first post i can't post URL..)
Because i got some issues with my phone and support told me to try it.
But when i follow the tutorial, launching "donwload" and connecting the phone, nothing happening..
The phone turn on, and display recharging logo, and flash tool still wainting.
Recovery mode -> "No command", Volume up + power is working, i used it to wipe datas
But at the moment, i'm still blocked, since 2 days, i dont know what to do
Can someone help me?
Thank you by advance, i hope my english isn't so bad

Yes you can use SPFlash tool evenif the phone stucks in the boot screen. Simply switch the phone off, start SPFlash tool and then connect the phone to usb.
If you follow the instructions from elephone, then your phone should working again: http://bbs.elephone.hk/thread-1037-1-1.html#.VofQ13wvdpo
Cheers
Hi, and thx for the help.
The driver is correctly installed now, i had to allow unsigned drivers in windows parameters.
So, i followed the tutorial, again.
I configured SP flash tool, clicked download, and then connected powered off P8000 with USB.
But, again, the phone displays recharging logo, and flash tool still waiting...
The phone is recharging so the USB is working, so i don't know how to make my PC detect the phone......
Is there a way or a thing that i missed?
thank you..
EDIT: i finally got a timeout error from flashtool..
I missed something, but what !? i can't remove P8000 battery, is there somthing to do to get it detected by windows?
Like a boot mode, or a magic formula... i'm open
For MTK Driver installation:
Did you follow skeletons Guide? http://forum.xda-developers.com/elephone-p8000/help/guide-windows-10-mtk-vcom-usb-drivers-t3264884
I'm sorry to say, that I do not have any experience with windows installation, this problem, because SPFlash tool performes on my 64bit Linux very well, without any driver trouble.
Cheers
Hi,
I'm on windows 8.
I used SP_driver_v2.0, that is an .exe
it's the only driver tips gived in most of tutorial
I allowed unsigned drivers installation, and i correctly installed it.
I tried too use flashtool before and after restarting the PC-> no changes
Flashtool doesnt detect the phone
I start getting crazy..
I have repaired mine, so i'll share

So the simple way to solve it is flashing the latest stock elephone p8000 ROM, which you can find on google easly
1. as described on other forums, you have to install the adnroid drivers, then get the sp flash tool, and have an un-zipped stock elephone p8000 ROM.
2. if you are stuck at bootloop, do the following to power off the phone so you can flash the ROM
1. Long press power button until power off
2.Do it fast--Press volume Up and then hold power button
3. choose recovery (volume up choose menu, volume down enter)
4. android logo with red triangle is displayed( "no command")
5. hold power button and press volume up
You're in recovery mode
3. select power off
4. open the SP flash tool >go to download tab>opne "scatter loading"( you will find it in the Folder where you unzipped the stock elephone p8000 ROM, if you have more folders there, chose "firmware" folder)
5. on the left side, under scatter loading, you will find a "pull-down" tab - it will be written "download" chose "firmware upgrade" or "upgrade"
6. start the process, then connect your elephone p8000 (it must be powere off) via usb cable to the PC, the process will start,and in less then 5 Minutes you have a factory new Elephone p8000 with the latest good update
7. WATCH OUT- it will erase all your data, absolutely all your data on the phone, except SIM and SD card.
Hope it helped, if not, feel free to ask me =)
Hello,
I have similar problem. Bought P8000 5 days ago. Did update today. Bricked. Stuck at logo ... I tried to flash but SP flush tool but the process isn't starting. When I downloaded ROM I received long list as on the screenshot: kaczorowscy.name/Screenshot.png
I have ubuntu - I see lsusb and dmesg see the phone (it is shut down from recovery menu) but maybe I am missing something ....
Ok here is what id did:
1. Get SP flashtool
2. get newest stock ROM
3. Shut down phone through android recovery menu (start phone with holding volume up, select recovery mode, wait for dead android, hold volume up and unblock button for 3 sec.)
4. Open SP flashtool - use "format all + download" of ROM (unzip and select scatter file from rom) - click start
5. Connect shut downed phone
6. Dot OK! from flashtool
PS. Flashing removed IMEIs - they are both written on the battery - you need to use android service menu to check them with special codes and reboot the phone.
Thanks ALL! :good:
Fix - Recovery Mode

When I was trying to root my p8000 I couldn't flash a custom recovery, fortunately I discovered that to access recovery on stock android you need to go to the screen with the android and "no command"/"no order" text and hold down Vol+Up and Power for 3~ seconds and then release power, this will boot you into recovery mode, If wiping cache/factory reset isn't enough "fastboot flash recovery <image>.img" SHOULD work now
hope this helped

Really Screwed Up - need some guidance

I hope I didn't end up with the proverbial brick, but I think I did. I was trying to restore my D-850 G3 to a native CM12 state to give to a family member. I did a good job with it but got stuck on not being able to change some settings. So I decided to wipe the cache and do a fresh install of CM12. I got far too aggressive and ended up wiping out everything. I have no recovery file on internal or external storage that I can access, and it appears the entire operating system is gone. I can't boot into recovery. When I try Power+volume up, nothing happens. I just get the LG startup screen and it's locked there. TWRP was on the phone but now I don't know if it is or not. If I could get to a menu and flash TWRP then CM12, I'd be OK I think (I just did that on the OnePlus 3). But I don't know how to get into the bootloader. I can probably find another way to load files onto the microSD card if that's necessary.
I tried downloading and using various LG support tools but I can't even get it recognized on USB - no adb, no fastboot, no way to get to anything.
I'd love to be able to rescue this phone from death but it's looking bleak.
Is there any hope here?
Do you remember which software you used?
I tried it on my laptop and I know it works with other phones (that aren't bricked), but all the G3 does is charge.
I installed LGMovileDriver_WHQL_ver4.04 and nothing.
Also LG PC Suite and it doesn't see anything.
I'm on Windows 10 - I do have an old PC running Win7.
If I could just get the device recognized via USB, I think it's salvagable.
To enter twrp its "power" + "volume DOWN"

...And select " Factory reset " then " Yes " and you'll boot in TWRP !

Nexus 5X dead -- need help -- wont boot

Nexus 5X - was working fine all this while till about yesterday evening.. then suddenly when i causally checked, it was in powered off state.
Normal press of the power button did not work. No response. Pressed Power button for 10 seconds -- google logo appeared...... and that's about it -- it powered off again when OS/Android started to load. (no android boot animation).
Tried to boot to fastboot -> was successfull. Phone stays alive in fastboot mode.
Tried to boot into recovery (I had TWRP). Again, shows google logo and then when TWRP screen shows up - phone shuts down.
Dont think its a power button issue - since in fastboot/bootloader mode, the power button and rest of the buttons work as expected & the phone does not reboot.
Battery is fully charged using official charger.
Further, in fastboot mode, i am able to access/push .img files - so that way, i could push full factory image (with no errors, including userdata) & relock the boot-loader & also install the factory recovery.
I can now get into factory recovery -- but nothing much.
One thing i noted was, while in factory recovery, if i try "Apply update from SDCard" option, it says its unable to mount /sdcard (error).
The phone was purchased directly from google & is under warranty.
Have had nexus 4, nexus 5 without any issues in the past.
This nexus 5x --- has been replaced once in the past due to yellow screen issues ...
Any help/fixes will be appreciated...

if you press hold power + volume up you go into download mode. there is a thread with all official MM and N roms, so you should be able to install one and hopefully fix your problem. ofc do a clean install
if that does not work, then you might have more luck with lg flash tool to do a factory reset
if nothing works then imo its hardware problem, but since i am not as good at such stuff as most here i refrain to say so

Verizon VK700 10.1

LG Pad Verizon 10.1 VK700
My tablet was stuck in upgrading firmware mode whenever I booted it up. Used LG tool to flash stock firmware, and it would hang at 28%.
Went into recovery mode and clicked wipe cache, and when I rebooted it now says
boot certification verify and the top left with the LG logo and it hangs here.
Can no longer enter download mode to reflash.
Recovery mode still works, but none of the options work
*Wipe cache (top of screen will say boot certification verify and hang)
*Restore factory defaults (will hang at Restoring Factory Settings)
*Safe mode (reboots to boot certification verify and LG logo)
Figured I could try to use SRK tools, but nothing comes up in my Device manager when I plug it in anymore (not even qhsusb_bulk)
When I power it off and on with usb plugged in, windows will occasionally make the new device detected sound, but then make the device disconnected sound about a second later, so nothing will appear in device manager.
Does anybody have any suggestions or any way I can get this thing running again? Or anyway I can get my computer to even recongnize it as qhsusb_bulk so I can use SRK tools?

If I remember correctly (please check threads here, it's been a long time since I've used this device, so memories are fading), download mode is activated when you press Volume Up (or both of volume buttons) and insert USB cable. I know that E98x has some strange button sequences, like rebooting to recovery is a two step operation (Volume Up + Power until navbar blinks, then power button twice, that's the only way mine wanted to boot into recovery), so please check around.
As far as USB connection issues, don't use USB3+ ports and if you're on Windows 8.1+ and later, run with Administrator privileges. I never experienced that one (used LGFlashTools from inside VirtualBox running Win XP for all my needs, I'm not a Windows user), so can't really help much but forums are full with explanations how.

2. Download LG USB Drivers from http://lgflashtool.com/
3. Install LG flash tool and LG USB Drivers
4. Plug usb cable to phone
5. Hold volume buttons and then plug the usb cable to PC (i use win 10)
6. Voila, the Download Mode icon is showed up
7. Run LG Flash Tool (Administrator privilege) & follow the instruction (i use e988 v20c stock firmware)
8. Phone back to normal (only if you use the correct stock firmware)
A very big thanks to ShadySquirrel
Hopefully this thread can also be used as reference for anyone who has the same issue as i had
