[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 !

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

How to root TP-LINK NEFFOS Y5L ANDROID 6.1

Hi everyone. Just like in the title of my post. I've just bought a TP-LINK NEFFOS Y5L smartphone, and I started to looking information, how I can get root for this device. And I found it:
https://morfitronik.pl/android-root-smartfona-neffos-y5l-tp-link/
Sad that this site is`t online anymore, but u can find it on github or gitlab.
I've flash this recovery, and it's working fine. The next step to root was to download the zip package from the chainfire site (currently abandoned, but u may use magisk from xda) :
https://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip
Latest MAGISK:
https://github.com/topjohnwu/Magisk/releases/download/v16.0/Magisk-v16.0.zip
Well, I've done it. It's working, and I have root on Android 6.1.
Here it is :
View attachment recovery-neffos-y5l-tp-link-twrp.apk
u will have to change extention of file from *.apk to *.img due to xda registration of size file uploaded.
Tutorial how to do this:

Hello,
I am a bit new... It seems I can't use flashboot mode.
I have DL ADB, then when I key : /adb devices, I see my Y5L.
Then I try to relaunch my device by pressing the VOL + / Restart button => I reach a picture of android and 3 japanese (or chinese characters).
When I plug the device to my PC, it seems that nothing happen (like it was not recognised by the PC).
Du you have any idea?
Best regards

Hello. It is a very annoying thing, but also very simple to solve. If u see the broken robot when u trying to enter to recovery, u must push and hold power button and short press vol+. But if you want to go to recovery or fastboot mode, u don't have to power down your phone. Just go to cmd (or whatever) console and write:
" adb reboot recovery" to boot up you device in recovery mode or
"and reboot bootloader" to boot into fastboot mode
Seeia.

Greetings!
The custom TWRP link does not seem to work as it should be. Either that or I am missing something
Could you please re-upload the recovery file?
Thanks!
"edit: I found it"

Can someone write a tutorial please, it's the first time i try to root with TWRP and i don't understand if the bootloader method for emample is from the device or from the pc because i can enter to the official android device (Y5L ANDROID 6.0.1 ) recovery menu but when i choose to boot at bootloader the phone freeze at the logo. Thanks a lot for any help.

1. pressing the VOL up + Power button => reached a picture of android and 3 Chinese characters (means no command !)
2. pressing again the VOL up + Power button => then you will reached recovery mode.

I had seem this polish method but I get afraid because there is no method to recovery to original rom.
I hope to see a custom rom in next days.

thanks

Hi, I'm trying to install the custom bootloader but after running:
abd reboot bootloader
the phone gets stuck on the tp-link logo.
Trying with volume-up + power shows the broken android logo, from there, holding power + vol-up gets me to recovery but neither fastboot nor adb detect the device. Selecting the "reboot to bootloader" option there ends in the same lock on the tp-link logo.
(I did activate the "unlock bootloader" in developer options.)
Any ideas on how to proceed? thx in advance.

Yeah i also had this problem, open at the android menu your phone and make sure you have enable developer settings and USB Debugging, install Wondershare MobileGo at your pc ( you don't need to install the app at your phone) and connect your phone with the pc, wait to find the drivers at the charge usb selection and after that swap from your phone to all 4 settings of usb connections, mobilego will download 4 drivers total and after that it will read it.
I cant post a link but if you have Chrome to translate from polish to english there is a new simple tutorial, go at the first link at the op post and at the site click at the red text at the beginning next to "twrp" text and translate to english for guide.

A little offtopic but, any idea on how to enable diagnostic usb port on this device? Nothing in this guide worked so far: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

hi
Why does not this mobile display the number of unread messages (sms)?
Why can not I choose one or two SIM cards in my message program?
Why does not the percentage of battery remaining up the screen?
Why does gps work too slowly?

Soft Bricked Fix needed (stuck on app optimisation)

Hi guys,
my wiley fox swift gets stuck in a continual optimising apps cycle. I can't enter recovery mode, when i press power+volume up it enters fastboot
(only see the black fastboot screen can't do anything). I did not change anything on my phone (not rooted) it worked fine yesterday and today i can't get it to work.
It's always optimising apps, if it's finished then i see the cyanogen logo and it starts optimising again shortly after.
I removed the battery and did wait about 15 minutes before putting it back in, i tried waiting (after 2 hours+ of it optimising i gave up),
i does not get recognised when i connect it to the pc (although i only used it to put stuff on the sd-card before) maybe a driver would fix this but i'm not sure which one.
I'm pretty clueless right now and i would be happy if someone can help me.

Saw the same thing on a friend's device today, used fastboot to factory reset the device. Insert USB in a powered-off device while holding vol+ then using fastboot do a "fastboot -w" to factory reset and recreate the (probably corrupted) data partitions.

i installed the minimal adb and fastboot connected my phone with my pc started it and tried it.
it doesn't recognize my phone and is stuck "waiting for any devices".
what can i do now? i'm not very experienced with android phones and fastboot.

ADB needs debugging to be enabled in developer options
FASTBOOT will only work if the phone is in bootloader mode

I already said in my first post:

since i never changed anything in my phone I haven't enabled debugging in developer options, if I could access the bootloader mode I could reset my phone but like i said,
it enters fastboot and not the bootloader from which i could enter recovery mode
under these circumstances, can i do anything?

see here https://wiki.lineageos.org/devices/crackling/
Note they call bootloader mode Download

Ok i can access recovery mode now (it was explained wrong here)
i tried to factory reset but the problem still persits.
in recovery mode i did go to ->Wipe data/factory reset then i had the options (No/No/Yes -- delete all User data/No)
i choose the third option and it did load a short while. after a reboot it still wants to optimise apps.
what's the best option now? i can choose (Apply update\ Wipe data/factory reset\Wipe cache partition\wipe media\reboot to bootloader\View recovery logs)

Fix
Hi,
I had the same issue and wrote the Wileyfox customer support.
They provided me the following instructions to fix the issue:
Download:
* 1 - ZNH0EAS2NH
* 2 - ZNH2KAS7EB
* 3 - TOS111B
Repeat for File X in [1, 2,3] :
* Goto Recovery
* Update your phone using File X
Since this is my first post I am not allowed to post links.
Find the full document including file links here: h t t p s : / / we . tl / B1IpUP6wtB
Already after running the first update my phone booted again.
Only thing I noticed is that the UI feels a little laggy / slower than before.
Regards
