i try turn it off but it always return to flickering twrp screen
is there anything i can do ?
thank you

With the help of Odin or Heimdall, you can go back to Stock ROM.

but i cant get into fastboot or bootloader at all
all i see is blinkin screen with twrp
so they not recognize the phone

You could not overwrite the bootloader, so it should work. What kind of phone is it?

You are switching to RUU mode with the command 'fastboot oem rebootRUU' so you are in the wrong mode for flashing/booting into custom recovery.
Reboot the phone and try again without the 'rebootRUU' command.

[Q] I am in need of a ton of help

Let me guess, you installed xdaddeb's boot stack at some point. Get the download mode restore from his link, it's in my signature. Flash that in recovery.
Also don't flash the CM11 nightlies, they are built from JB drivers/kernel for the G2 and won't work with the KK basebands...

I believe I did flash that at some point. The only problem with that solution is I have no recovery I only have fastboot that is the only thing it will boot into knowmatter what I do.

You have Fastboot? Did you try downloading the latest TWRP img file and doing a fastboot boot recovery.img or fastboot flash recovery recovery.img? (I really don't know if it will work)
Download http://dansroms.com/G2-TWRP/custom-twrp-2.8.0.1-vs980.zip and extract the recovery.img from that and use it.

I hope u reflashed the recovery
But I can't access the phone past the lock pattern so I can't access the adb for rebooting to bootloader so I can't flash the recovery

Can you boot to erecovery?
No, I can't
U can boot in bootloader without pc and accesing phone. Just turn it off connect usb to pc and to phone and when u put it in the phone imidiatly hold down volume down button and u are in the bootloader i wipe so many times my system from twrp recovery and i thin i cant acces but this method saves me.
Just reflash the firmware via Dload and then try again
Yep but it fails getting an update. And now since I got fastboot working and flashed system.img I can't start even the system anymore. What to do now?

By dload method as suggested by shashank.
I tried dload but it just says "incompatibility with current version"! Is there way to flash update.app or update.zip via fastboot? Where can I get that so called "android-info.txt"?

Why is android info txt needed?
You can flash userdata, system, boot and recovery via fastboot.

Lost TWRP and system after flash custom rom

Hi guys,
I flash Havoc-OS on Mi9T Pro Global PFKMIXM 10.3.1 by TWRP, after reboot do not start system and not enter on TWRP again.
I try this commands on fastboot below.
Code:
adb devices
fastboot flash recovery recovery.img
fastboot boot recovery.img
fastboot reboot recovery
Can anyone give me a help?
Thanks.
fastboot devices
fastboot flash recovery recovery.img
> now just push volume up + power to boot to twrp. (those boot and reboot not working some reason always)
... i tried use same custom rom, but fail also. Then i test LineageOS, that boot normally. I used EUxxx ROM before and after. I just got enought to test custom roms so far.

Hi friend, mainly thanks for helping.
I tried your suggestion, but it doesn't work.
I restored with Mi Flash Tolls, the only alternative. Now it works well.
You will now try the Flash I Rom and waiting for new updates and then flash any custom rom.
After I want share stuff tools and congratulations.
Have nice guys!
I have the same stuck in fastboot No recovery img, no rom loaded so cant use XiaoMiTool
I booted into TWRP but it didnt ask me for my dycrpt password or somehow i wasnt paying attention and when in with cancel.
I was preparing to flash a new ROM so i wiped all but user data then went to flash my ROM and found i was in the wrong partition

Yes, that's what happened to me.
The only solution I found was to install the new rom via fastboot.
For this you will need to perform the following steps:
1 - Install Mi Flash + drivers (this is boring, if you have Windows 7, it will be easier). In this link you will find some downloads and more details.
2 - Download the Sotck Rom (for fastboot important) from your device, in my case it was PFKMIXM 10.3.1 for Mi9T Pro. You need to extract zip then before.
3 - Flash the new rom via fastboot (approximately 10 minutes).
After that, your device will start with the new rom, then you can flash TWRP again and everything will work. The Magisk installation may cause error 1, but only flash boot.img through TWRP.
Be quick, because if the battery drain, you won't be able to start it in fastboot again.
If you need any links, ask me. I didn't have time to share everything.
Have a nice and good luck!!

To boot to recovery After fastboot flash recovery , you will need also a system...
As you wiped all, you dont have anymore. I made the same mistake when decrypting After unlocking.
Extract system.img from stock fastboot rom and fastboot flash system system.img.
Then again (why not lol) fastboot flash again reco and reboot to recovery with buttons.
If it dont work , miflashtool will recover it ( DONT SELECT CLEAN_LOCK)

Yes, very important.
In Mi Flash, check only "Clean All" dont clean and lock.
Thanks.
thanks, hopefully i didnt break it further as i accidently flashed a global indian ROM when i should have flashed CN
now my only option might be EDL via testpoint, i have a mate who can help i will try and find the right version CN rom tonight and go slower

Thank you for sharing your experiences.
Too bad you couldn't recover. I hope you can do it again.
Today I had to flash twice, once because I flashed Kernel Quax and couldn't rollback and once for trying Rom Syberian. I hope that in the future we will have a firmware balanced with the customs kernel and roms.
Good luck.
Thanks I dont think it will work
i bought a Deep flash cable to see if i can get it into EDL mode without opening.
