Hi
i have a problem with my G4 H815, i can't access fastboot mode even throw adb commands or throw quickboot apk the phone restarts immediately
the same thing with download mode it restart few 3 or 4 seconds after showing download mode screen
anyone can help please
thanks in advance
Same Here... Any Idea ?
I actuallay am in the same situation with my brand new LG G4 H815 that I have just unlocked.
Everytime I try to get access to the fastboot mode, I get confirmation that my bootloader is unlocked (message on screen),then directly to a normal boot, so I can't flash anything.
If anyone has an idea to solve that it would be much appreciated.

Same thing here. I can only enter fastboot from an adb shell, but today's CM14 update doesn't boot so no ADB shell, now I'm stuck with a phone that can't fastboot.
Moreover, CM14 recovery just displays "erasing' then reboots.
Hi,
I appeal for the community help to try to get rid of my tablet "boot-loop" !
Here is the situation today :
My tablet no more boots on Android. It starts on what I believe is the bootloader (see screenshot) but this original bootloader doesn't allow me (through volume +/-) to choose between the usual recovery/boot/reboot choices. I can't do anything except a long press on power to switch off the device. On this "bootloader" screen, I fortunately can send fastboot commands.
What I can do :
- fastboot reboot => ok, the device reboots and comes back to the same screen
- fastboot continue => most of the time (if not always) it does nothing, but some few times (I can't manage when exactely) it continues the boot and goes to the loading screen with ASUS image and loading spinner, but the boot doesn't go further : I let it a full night and the device was still on this screen.
- fastboot flash boot boot.img => ok. The image (from a zip downloaded on ASUS website asus.com/Tablets/ASUS_Transformer_Pad_TF303K/HelpDesk_Download ) is flashed successfully.
- fastboot erase xxx => ok, clean the partition
- fastboot oem unlock => FAILED (remote: Invalid signature, fail to unlock!!)
How I finally get here :
I wanted to root/unlock my device, except I may acted as a newbee ! Finally, today, I don't really know what is the whole set of commands I have sent.
I saw too late that ASUS provide an unlocker tool. The problem was I was under an official but too recent android version to run this tool.
Some information :
A few month ago, I had this issue, and, by insisting I managed to boot normally and fully on android. At this time, I told myself that I will never switch off the device, but, this happened !
So, today I need your help :
Do you know how I can get rid of this bootloop ?
Does the screenshot is really what is called the bootloader ? (even with no volume +/- control ?)
I saw it exists a tool named "ASUS Flash Tool" but it needs "raw" images and not zips like we can download on the ASUS website. Does anybody know what are this raw files made of, and how I could eventually convert a zip to this raw format ?
If anybody have original backups of the TF303k, they may be very helpful for me !
Thanks for any help or advices ! :fingers-crossed:
An ultime little up... :crying:
Edit : Or if anybody have a TF303K, if you can send me a backup of your system partitions, I'll really apreciate it ! :fingers-crossed:

Exactly the same here!! Any news? How to fix this 'always boot to fastboot but I can still get into system by using fastboot boot boot.img command'?!
EDIT 1: This ASUS specific fastboot command seems to be a big life saver because it RESETS the Tampered Flag to False: "fastboot oem reset-dev_info"! Hurray!
fastboot oem reset-dev_info

Yeah, this did it for me too! Thanks a lot!
How did you get knowledge of this flag?

If you are thankful, please press Thanks button under my posts
The Tampered Flag is an OEM specific thing, and all fastboot oem commands are specific per brand and type.
As the ASUS TF303K is a clone of the (ASUS) Google Nexus 7 (2013)(Flo), I read ALL stuff on the Nexus 7 (2013) everywhere. You'll see this command a lot.
Unfortunately the Nexus is unlockable (fastboot oem unlock), and ours is NOT in any way.
One of the best posts is this one.
Still hope ANY one can help us unlocking the bootloader, or help us on how to flash another ROM (Nexus 7 2013?) to our device using Qualcomm tools (QPST / QFil / MiFlash etc etc)? :'(

It didn't do the job for me
I still get an endless waiting screen when fastbooting boot.img.
Can anybody would accept to dump its partitions ? (system, boot, and recovery) ? This should do the trick and may not require root ! Thanks so much !
Excuse me, ask, bro.
My cellphone Realme 3 is 4/64 RMX 1821
I tried Unlock Bootloader using the in depth test and it worked but after trying to root it went into fastboot mode there was writing fastboot mode verification fail. And always reboot like that, don't want to enter fastboot mode. As long as the power button is pressed + down fastboot mode it always fails and repeats until I release all relame 3 button automatically reboots as usual.
Is there a way to fix this failboot fast mode?

I had the same problem a few times lately.
The best solution is to boot in bootloader then under windows enter :
fastboot boot twrp-3.5.0_9-0-kuntao.img
(or any twrp you downloaded) it will boot the phone in recovery and you can wipe and sideload a rom.
i fastboot my realme x2 ,i try to install recovery .img but failed,but after that i install orange fox recovery .i flash the stock rom of realme and it stuck in bootloop .when i press power button its goes to fastboot screen ,it goes shunt down in 5 sec and again come to fastboot mode .plz someone tell how to solve it
