hi guys, thought i would just hit a new thread.
My problem is, i tried to install custom rom.
When i was in fastboot initiate command # fastboot oem unlock (serial #).
Lenovo give press Vol up for Yes, Vol down for No. i hit no and it unlocked the secureboot. now. i iniate another command # fastboot flash recovery recovery_twrp.img.
and there it keeps looping the lenovo logo. i cant access ADB and fastboot. Tried to install drivers for mediatek and lenovo preloader usb vcom. but it cant stablize because it keeps looping.
Any ideas pls?
tried spflash tool but got scatter error 8417.
Maybe flashing a wrong version of twrp recovery image is the cause right? if i can only access back fastboot.....

Hey all,
So Ive tried to unlock my bootloader but its not working, ive followed the steps from this site to unlock it but its stuck on the unlock bootloader screen. I have two options to choose from yes or no I click yes but it doesnt work, yet I click no and it takes me back to choose from fastboot, recovery and normal. My phone is a Alcatel Pixi 4.
I have enabled developer mode enabled usb debugging. I also have confirmed the RSA fingerprint for the computer. Also I have enabled OEM unlock in dev settings. This is what my cmd prompt window loooks like. I will also take a photo of my alcatel frozen on bootloader screen.

I can't unlock my infinix hot s3 bootloader
I've enabled developer options, allow oem unlock, and enabled USB debugging.
My PC is setup for adb and fastboot and my device is detected in both modes. And responds to commands
Yet fastboot oem unlock gives me an error
FAILED (remote: oem authentication failed, please get right authentication f')
Also tried fastboot flashing unlock
Same error.
I need help thanks

Any CUSTOM ROM AVAILABLE FOR INFINIX HOT S3?
I tried using the Tool All In One to unlock the bootloader and manually through the adb and fastboot terminal. ADB recognizes the device even though every time i reboot to bootloader through adb or manually through the phone recovery and manual buttons it never sends me to the bootloader. i was able to flash the stock firmware with SP flash tool. I really just want to install TWRP. i have been able to root this device with Wondershare dr.fone root program. I wanted to get it to work with the All in One tool so i can install TWRP to install custom firmware. If anybody can point me in the right direction on why the bootloader never works and fastboot? Maybe this model the bootloader is unaccessible? And if i cannot get to fastboot to unlock the bootloader can i still install twrp somehow. Also when using fastboot command it shows the device id it just says waiting for device everytime and cannot get it to recognize past that point. Not being able to get past this phone problem has been really bothering me and irritating me lately so hopefully i can get it resolved. I will be back later to see if anybody knows a solution to this. it seems like i have been trying to do the same thing and maybe im right and fastboot mode and the bootloader is locked and currently not possible.
