Edit: I managed. Thanks anyway!
I done goof'd when trying to flash custom recovery, now phone gives "secure booting error! Cause: boot certification verify" when trying to boot.
I'm unable Fastboot - all the tutorials I found give me wrong instructions (*more details at the end).
So I'm trying to flash stock rom, but every flashing software I tried either had a broken download link (LG's official site is hot garbage), Needs a password (seriously, why), or doesn't run on my perfectly fine, modern enough PC (Ryzen gen 2).
Any help? With either a normal Flashtool (please link), or a way to enter Fastboot?
*Volume+ power, release when logo appears, then holding down volume+power again brings me to factory rest. Not even recovery. Choosing "Yes" on factory reset does nothing.
*Powering off, then holding volume up while plugging in the USB brings me to download mode. Keeping the same butting still held does nothing.
*Powering off, then holding volume down while plugging in the USB does nothing (boots normally, then displays the booting error I mentioned earlier).
I have similar problem with LG G2 mini: Secure booting error: Boot certification verify. I tried turn on download mode but I can not turn on download mode. I tried t flash smartphone by flashing software LG flash tools but this program hangs. Exception code: c0000005. Can you help me?

Hi, i've a strange (but i hope common and resolvable) problem.
After all, i say that i searched through the forum (with the search function) but with the solution that i found and tried i didn't solve anything.
I start saying that i got a p500 with a broken sdcard reader board (it simply doesn't have a microsd 'cause doesn't recognize).
That phone some days ago just shut down and went stuck on the LG Logo.
I tried at first the hard reset (home+vlm down+pwr), nothing happens.
I tried then the recovery mode and try to update with lg updater, and didn't work, lg doesn't recognize the phone on the updater (but on the main screen of the BBc app does).
The last thing that i noticed is that one time, powering on the phone, button's leds flashed about 4-5 times. but if i try to re-do the action, doesn't get anymore.
I would know if there is another way to exit from this stuck-screen.
I also post the log of error i get from kdz:
Upgrade error
WParam: 100
LParam: 500
Here is the log: http://pastebin.com/4SECdaT4
Other things i forgot to say:
I don't need to shake the phone, if kdz doesn't detect, i take off the battery, and turn on the phone in emergency mode (up+back+pwr).
Sometimes kdz works without that error, but it reboots the phone and it stucks again in the lg silver logo.
I read about a wipe of /system through adb, but if i try to mound /system, i get the command list.
I can't do adb devices, doesn't detect the phone, and in sequence to this, can't open the adb shell.
any suggestion?
You recovery got corrupt when it was stuck on LG logo, which could be easily solved by fastboot method of recovery flashing.
I was on the same situation like you are on now. Now follow this:
Try booting into fastboot mode by pressing "Power+ home buttons"
If it does then notify me here or at PM.
Between this is not the appropriate section for this thread.
I tried to fastboot, i did fastboot erase recovery and fastboot flash recovery recovery.img commands, no errors, but when i type fastboot reboot, on the screen i read: rebooting the device, but it doesn't reboot. If i take off the usb cable, (after a big time, 10 mins for example), a --suspend-- appears.
if i take off the battery, the lg logo is stuck again, and if i do home+vol down+pwr the clockwork mod doesn't appear.. any suggestion?
See your PM

Hello everyone, I have an archos 50d helium Android 5.1 Lollipop, which practically when turned on remains locked in the logo screen, the one with the archos logo and does nothing, does not continue and therefore does not turn on. I turned it on with the vol + key entering in recovery mod and doing the various wipe cache, total formatting, but nothing has changed, the phone remains locked. I tried to download CWM and do apply update via sd but any file I put (even the phone's firmware i tried like 10 .zip file) has always given me E: footer is wrong, signature verification failed, Installation aborted. While trying to turn it on with the volume key - it does nothing and does not go into download mode. As soon as I put the charger on the phone, if it is off, it turns on and remains locked in the logo (Archeos), but I think it charge because it stayed for a long time in recovery mode or in logo mode. Obviously the phone does not turn on and I can not use it in the download mode because it does not enter or use odin. So I have no idea what to do with it. I was just installing an app, it turned off and from that moment on forever it seems. What do you suggest to do? Thank you. :fingers-crossed:
up
Afternoon
I have a Lenovo 7" tablet which is sticking on boot...to describe:
tablet off, charge screen working fine (green battery)
can get into menu to select fastboot mode or recovery
fastboot works, at least screen appears!
recovery shows dead android/no command screen - how to access recovery?
booting up, get inital orange logo then a 'bing' and start of boot but then freezes on the second logo
tablet not visible on PC, even in fastboot mode (have installed drivers)
I'm looking to get this going but am a bit stumped. I tried reinstalling firmware but can't get SPF Tools to work with any available scatter files; I would like to install TWRP (I found a potential image file on XDA) but can't do this until the PC recognises it....and I'm going round in circles now....any suggestions gratefully received. :good:
Update
OK, post was maybe a bit premature - I've kinda fixed my issues.
Managed to get into recovery after watching many videos (most of which were wrong, but hey-ho, got me on the right path!). At dead android screen, press and hold in power + vol up + vol down together (there is a bit of knack, turn it on its side with buttons facing up seems to be easiest) - this fires up the recovery screen (android standard recovery).
I managed to get over my bootloop issue by performing a data wipe/factory reset and cache wipe, then restarted fine.
As this was a secondhand tablet (my usual purchases - good condition bootloops!) - once it booted up I got into the set-up screens only to discover a Google lock issue. I ran the FRP unlock from here: https://androidfilehost.com/?fid=11050483647474832839 using the instructions from here: http://forum.gsmhosting.com/vbb/f958/lenovo-tab-4-7-essential-tb4-7304f-frp-remove-2322527/ (Voltrans second post, not the original one which has a 404 error on the download site). This removed the FRP lock straight off and now I have a functioning tablet.
I'm probably going to try getting custom recovery on so will see how that goes - I'll post back
and...that's all folks....
OK, despite finding a TWRP recovery online https://twrpbuilder.github.io/downloads/twrp/#441 and downloading it, can I get the fastboot unlocked? no.
Apparently Lenovo locked them all up and threw away the key, so nothing more can be done here.
I tried various iterations of fastboot oem unlock and fastboot flashing unlock, and nothing works, just get an error - and yes, I did put developer options on, OEM unlocking ticked and USB debugging active.... :silly:
So, unless someone can point me in a direction on how to unlock it - I've reached the end of the road with this one
Hi everyone, I just received my Teclast M30 (10-inch tablet), version M5P3. I tried flashing a custom ROM but - surprise - I'm stuck on a bootloop.
The stock ROM was an Android 8 version. It is not rooted.
- I went into the developer options and allowed Bootloader unlocking via the corresponding option.
- Then via fastboot, I unlocked the Bootloader via (without any error):
Code:
fastboot flashing unlock
- Flashed TWRP, found on the only Teclast M30 thread... (=> https://forum.xda-developers.com/showpost.php?p=81064235&postcount=56) via fastboot (without any error):
Code:
fastboot flash recovery twrp-3.3.1-teclast-m30-20191201.img
- Flashed a GSI (ARM64 A-only) ROM (without any error). I used the "Android 9 - Havoc-OS v2.9" ROM on this link => https://github.com/phhusson/treble_experimentations/wiki/Teclast-m30-(MT6797x-helio-x27))
Code:
fastboot flash system Havoc-OS-v2.9-20190914-phhgsi_arm64_a-Official.img
I realized after a few hours that the TWRP I used was for the M4P7 version and mine is M5P3.. so I now know what I did wrong but even with this info, it doesn't help for my problem.
When trying to boot after flashing, I'm stuck on a bootloop.
It shows the Teclast Logo with some text saying it's in Orange State (= show a message saying the is bootloader unlocked) and then go to a screen with an Android Logo and a message saying: "No Command".
This "No command" screen is well known in our forum BUT problem is this screen stays only for about 3 seconds, and then the screen become black for 1 sec, then the "No Command" screen appears again for 3 sec, then it disappears again, endlessly. Here is a video of what's going on https://www.youtube.com/watch?v=O1iiu6MtOyM
Pressing "Power & Vol+" or "Power Button & Vol-" on this screen does nothing, I just can't enter fastboot mode as it keep looping and do not stay on the "No Command" screen.
When the tablet is completely shut down, I tried powering it up pressing just the "Power" button, but also "Power & Vol+", "Power Button & Vol-" but it does the same thing every time. It also acts identical whether the tablet is plugged in to the computer or just charging on the wall plug.
There is a "Reset" button on the tablet (must use a SIM pin to press it) but it seems useless to reset the device. When pressing it, it only shut down the tablet and stops the loop. I tried pressing it for long periods like 10-20-30 seconds in different situations but it just shut down the device and do nothing.
Does anyone have any leads on what I can do to revert back to original state or even just access fastboot mode ?
Thanks
I have the factory firmware file for my tablet (the good version this time..) now, but still the same problem of looping...
For future reference:
I fixed it thanks to the stock firmware and a tool (SP Flash Tool) that are both included in a file package provided by the constructor (at the time I created this post, this file didn't exist on their website. Now it does ).
This file is hosted on Baidu (only accessible with an account, and you need a Chinese phone number to create one) so I uploaded it on Mega if anyone need it:

Bye!
Hello community,
I haven't posted here before, so I hope I'm not doing anything wrong.
I have a problem with my Neffos X1 and after browsing the internet for hours nothing helped so far, so I hope some of you can help me out.
My phone is stuck in a bootloop since yesterday evening. I haven't done any updates or new installations recently, so it just happened out of the blue. It loads till the Neffos logo and then restarts over and over again.
Since I can't take the battery out, I tried letting it run out of energy and then restart, but as soon as I connect it to a power source the bootloop will start again.
I read a lot about getting it in recovery mode or to try and flash it, but no matter what combination of buttons I try, nothing is happening. The phone basically doesn't react to anything and just keeps restarting. The only thing I noticed is, that when pushing both volume keys the screen will just stay black (no restarting), but after letting go the bootloop will start again.
I tried flashing it via SP Flash Tools, but the phone also doesn't react to it.
Lots of troubleshooting guides also require, that I have rooted my phone in the past, unfortunatly I haven't. I also read about unlocking the bootloader, but since my phone isn't reacting to any buttons and my laptop also doesn't seem to recognize my phone (probably because it doesn't boot proberly), that doesn't seem like a solution either.
To summarize: I'm stuck in a bootloop with no recovery mode, no rooting, no unlocking bootloader, probably can only use my laptop to do anything remotely.
So, is there anything you can think of, that might help me get out of the bootloop? Or ideas of what I may did wrong when trying the other solutions?
Thanks for any help in advance.
Same problem
I have the same problem, I have tried all kinds of soft reset and nothing is working I also opened the phone to check if anything was not connected properly, but everything seems fine except for that infinite loop. Please help!

Try this
Download phone's Stock Firmware onto your personal computer.
Install the USB MTK Drivers - NOT ANY OTHERS (skip if you have them already installed).
Download and Launch the Smart Phone Flash Tool (SP Flash Tool)

Patiently wait for your device to be formatted.
After the formatting is done, a Big Green button will pop up on the SP Flash to show that.
Unplug phone and boot it up.
If you have a boot loop after booting your device, boot into recovery mode and do a factory reset.
Voila, you are all good.
