CM13 stuck at loading screen - G4 Q&A, Help & Troubleshooting

Hey Guys, thanks for stopping by!
TO cut a long story short- I'm stuck at cyanogenmod loading screen upon booting, after I stupidly tried tinkering and replacing camera.config files on a sucessfully installed CM13. I can not enter TWRP- it brings me to factory reset screen for some reason, I was only able to enter it through the TWRP manager app. I am able to enter download mode however, is there any way to unbrock the device? Would the KDZ method work or would it not?
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
In download mode this is what the device manager states. The computer doesn't recognise it as either adb or fastboot. Is there anything I can do?
Thanks a lot

This menu from LG you access with power + vol. down - "Factory reset" - will bring you to TWRP. Just confirm twice with "Yes" and TWRP will load.

Thank You so much! I didn't want to try anything by myself - that is how I completely bricked a device in the past. It works- than you SO much!

[Q] LG-V500 Secure booting error, boot to TWRP only.

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

Cant recognize phone in fastboot!! HELP!!

The phone is in bootlopp (i think).When i turn on appears android on groundb with the red triangle and a chinese word.This disappears and appears again,for an infinite time.Display stays turned on.Turning on in bootloader it works,but just in bootloader.If i try to enter in "Restart bootloader,"recovery,"normal boot"ecc it's in bootloop again.So i can access only bootloader at the moment.I want to reflash system,droidboot imgs ecc with fastboot but...tried to recognize phone on an old HP Compaq nx6110 with usb 2.0 and win7.installed on it adb drivers,adb and fast-tools.don't think zenf2 drivers are important at the moment,now should consider just the adb drivers cause i can access only bootloader.however i think zenf2 drivers are installed on it.nothing.phone no recognized by fastboot and no recognized by windows.consider that on a xp and 2.0 usb pc (with fastboot,adb,and adb drivers on it) phone is recognized by windows as Android-Phone but then windows says i've not the drivers for the installation (appears the drivers' choosing window).No asus driver on it,on the win7 pc there are!!

When you see the dead android with red triangle, hold the power button and keep pressing it and quickly
press volume up button and release it but keep the power button and you will see the Recovery options.
Then choose "format Cache" with volume up & down button and enter with power button to format cache partition.
It would take a long time so don't be alarmed. When done, choose restart system and the boot loop should be fixed.
Good luck.

Didn't work for me ... if I keep pressed the power button for a long time, power off the phone and it doesn't entry in Recovery mode...
I resolved with "fastboot erase cache" command
It is normal to get that error when selecting 'recovery mode'
The next step is a little tricky. You have to press and hold the power button, then press the volume up button. It may take a few tries. Both buttons will have to be pressed together simultaneous to enter Android system recovery. Please also see http://www.asus.com/us/support/FAQ/1011956/

Hi,
I´m having a problem with mine. Can´t recognize phone in fastboot but it´s different. I already asked for help in general thread - all resources (page 47 to 50) but still can´t solve.
I rooted my device using method 3 (one click root) and first everything seems fine, but on my first reboot i entered on bootloader - recovery and started a wipe cache, but didn´t finished it, push power button and force it of (i seemeed stuck there - was wipping for more than 10 minutes). Since then i can´t solve anything, tried many ways to unbrick my phone but i seem the problem was i can´t connect fastboot. After a lot o tries, i entered in TWRP using method 2 and wipe, made a recovery, everything and as magic i can enter again on recovery, even tried adb sideload (it started, but when starts to write something - at 50% of the process just ended). So, long story short, i did a flash of the original firmware i downloaded from asus website using method 2 and now it´s working as original, but i still having the same problem (or maybe worst, since i can´t enter the TWRP recovery using method 2 anymore) and can´t root my device. When i tried to do anything using fastboot it´s just shows "FAILED", When i request adb devices shows a blank line. If my phone is on, using android, it shows the correct serial number.
I don´t know what´s happening, it seems to estabilsh a connection (when on its ok, method 2 freeze on teamwin logo - the tool can write something on phone) but can´t write anything. i´m worried because i think i won´t be able to do any update and i wanted a rooted phone to.
Anyone seems a solution?
I'm having the same problem today and I solved it just now! I can't even open the fastboot and recovery. Finally I install the software "shuame"(I'm Chinese, you guys may find other software) on my PC, and with it my computer read zenfone2, and I use the function in the software to open fastboot mode, then I flash the WW version recovery.img and boot.img with a one-click tool in zentalk(TW), then I just double wipe, the phone is alive now !

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

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:

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.

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
