Wifi does not work on any gsi rom

I just installed Corvus GSI ROM following the above instructions, wifi works fine, almost everything works fine... only one thing is bothering me bad... I cannot adjust the brightness, it burns my eyes. I found a video on youtube in which it is said that this is something general for GSI... it's a sin! Anyway, thank you @carbon271!

I'm trying this with the Android 12 Beta 5 GSI, starting on OOS 9.0.11, but ending up in a bootloop. Has anyone else had any success with Android 12 GSIs on the 6t?

Troubles reinstalling TWRP [Failed to load/authenticate boot image: Load Error]

I dirty flashed a new version of xiaomi.eu stable build, and it caused TWRP to uninstall itself.
Whenever I hold power on and volume up it just goes to fastboot.
Now I tried reinstalling TWRP like I've done many times before, but it keeps throwing an error. The error I get is when trying to boot without flashing the img. When I do this, I get the error:
Code:
fastboot boot TWRP.img"
downloading 'boot.img'...
OKAY [ 1.609s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)
finished. total time: 1.675s
Anyone gotten any ideas on what could be going on here? I'm scared to try anything as my phone currently works, but I need TWRP back to update my phone to a different versions and to install the clock mod again.
Thanks!

Got it to load once, but now back to square one. Throwing same error.

Now when running the command fastboot reboot recovery it's saying
Code:
fastboot: usage: unknown reboot target recovery
And writing 'fastboot boot twrp.img' turns the phone off / makes the screen go black. Fully bricked now as the OS wont load either.

Try on a computer with a USB 2.0 port, or a different usb cable, had the same issue once

Ended up having to reinstall dev rom. Device relocked, so have to wait 15 days again. @BusterBg_18 Thanks, will do when I unlock the device
EDIT: When using Mi Flash tool, make sure to check 'clean all' and not 'clean all and lock' in the bottom right. That's what set me back 2 weeks.

I have the same error. How can I fix this pls?

Flash the latest official rom then start all over again. Follow the post above you about miflash.

Hello, I've had the same problem, then flashed latest dev rom via MiFlash and it booted, but now after I flash any custom ROM in TWRP i have this issue again and need to reflash chinese ROM. How can I flash any custom rom?

i'm stuck in the same issue. stuck in fastboot and it would not load recovery. any fix?

Hi, i fixed the "Failed to load/authenticate boot image: Load Error" by simply restarting the Device.
It seems to appear randomly when flashing partitions and then block all further Transfers.
If the Device loops in Fastboot, the only Solution to me was re flashing the Stock Firmware.

I have the same Issue, but reflashing Stock Firmware or making OTA Updates dident helped for me. Ive already tried TWRP and OrangeFox without success. The Screen always turns black and Fastboot stays active in an limited Mode, any Ideas? My host Computer only has 3.0+ Ports only, but ive used an 2.0 Extender so it should be fine?

3. vendor.img
4. dtbo.img
5. cust.img

BROOOOOOOOOO HAHAHAHAHAHA I LITERALLY JUST READ YOUR COMMENT AND 10 SECONDS LATER I FLASH THE ROM WITH "CLEAN ALL AND LOCK" Im a f-king dumb bro

Marihot said:
你好，我也经历过同样的事情。
这个方法帮助我摆脱它。
尝试使用 adb 从要在 hh 中安装的 rom 中重新刷新一些文件映像。
将下面的文件从 rom 映像复制到 adb 文件夹
1.system.img（adb >> fastboot flash system system.img中的命令）
2. boot.img（adb 中的命令，如#1，更改 img 文件的名称）直到 #6
3. 供应商.img
4.dtbo.img
5. 自定义.img
6. 杂项.img
7. 现在用adb刷twrp/recovery.img（选择twrp与你要安装的rom兼容）
8. adb 的“fastboot boot recovery.img”
9. twrp刷入rom

[ROM][STOCK][FASTBOOT][OP7TP] Stock Fastboot ROMs for OnePlus 7T Pro

Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via recovery (either stock) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.
HOW TO FLASH
This version is only for not branded devices
Download the zip;
Unpack the zip in a folder;
Reboot the OnePlus 7T in fastboot-bootloader mode (Power and volume + and volume-);
Connect the OnePlus 7T to PC;
Run flash-all.bat flasher you need;
Wait until the process end;
The phone will automatically reboot.
DOWNLOAD

MANUAL FLASH: Windows - OSX - Linux
If you want to manual flash these roms these are the commands (You need the latest sdk platform tools, you can find it here
Is reccomended to format data or the rom cannot boot:
Code:

Others Commands to flash a fastboot rom

fastboot reboot fastboot
fastboot flash system system.img

REMEMBER
"Invalid sparce file format at header magic" is not an error, you need to wait a bit when you see that string, just wait.
If the device automatically reboot in Stock Recovery mode don't reboot it and wait the flash end.
These ROMs can't be used to update or downgrade your phone but just to restore your phone.
If the rom seems doesn't start go in recovery stock and follow this guideline: English -> Wipe data and cache -> Erase everything.
If you want to rebrand your phone from HydrogenOS to OxygenOS you can follow this guide: Rebrand Guide

Hello! Can I flash this ROM to change from Hydrogen OS to Oxygen OS as per instruction "Rebrand guide"? Because on official website Oxygen OS ROM is not available for 7T Pro!

Can you (or anyone) post the oxygenOS build zip which I can flash via updater?
Right now I'm on hydrogen OS and want to move to OxygenOS by official means.

When the device reboots in recovery doesn't touch it

Silly question after returning to stock, I've tried to relock the bootloader and get a device corrupt won't boot message and the phone then turns off. How do I relock without this happening.

Wooot. Ok guys, i came from 5T and Root,TRWP and flash stock ROM was easy. Where do i have to begin, anyone can give me structured process of ROOT,TWRP?or FASTBOOT and ROM?

I had an issue earlier and begged support for the stock firmware, they sent me https://drive.google.com/open?id=171cVS9ku7rHF74Gyl1VGP3jQXAFwWDpl

Question Impossible to boot custom recovery

For my new Redmi 9T (EEA ROM, 2010j19sy) i wanted to install an unofficially twrp recovery but i was not able to boot any non-stock recovery out on the web. I also found that other people in this forum have the same problem.
The unlock and everything else worked without problems.
This qoute from GrandTouqe describes my problem exactly:
Rename the file change nothing to me.
As information, when I try in try
Bash:
fastboot boot recovery.img
i get :
Code:
Bash:
FAILED (remote: unknown command)
in fastboot
and
Bash:
FAILED (remote: Unrecognized command boot)
in fastbootd
I've test lineage recovery and that's the same : impossible to boot on other recovery except the stock MI-Recovery 3.0 .

My OS is Windows 10 on an x64 intel CPU.
The ADB Fastboot binaries are like 3 weeks old, may they cause this strange behavior?

I figured out that my product is not lime, its lemon now. Can anybody tell me what to do?

Hey !
I've found this one who works in this topic.
But after, I can't install the unofficial ROM that I find here.

Question Stuck in Fastboot after TWRP Wide data (unlocked bootloader)

Hello guys!
I am having issues with the battery (I think it's faulty) and I just wanted to reflash the EU MIUI Stable ROM to see if it's a software problem.
Currently with unlocked bootloader (no root) EU MIUI 13 STABLE and Android 12.
What I did:
didn't remember if I had TWRP installed and flashed EU MIUI 13 STABLE via Fastboot
MIUI 13 - MIUI 13 STABLE RELEASE
Status: RELEASED RULES WHEN POSTING 1. If a ROM is not published DONT ASK ABOUT ITS ETA 2. If a ROM is not published DONT ASK why! 3. If a ROM is available, download it and use it 4. If a ROM has bugs, post the bug to the bug section if the BUG is not already listed 5. If you use any form of...
xiaomi.eu
linux_fastboot_update_rom.sh was successful
but now stuck in MIUI Recovery mode after every boot
I guess I had TWRP installed and this is why it got issues?
So I decided to fix it by installing TWRP first, and then flash ROM via TWRP:
found official TWRP for Mi 11 here: https://forum.xda-developers.com/t/recovery-11-official-teamwin-recovery-project.4374109/
installed this via fastboot: fastboot boot twrp-3.6.2_11-0-venus.img
did "Advanced > Flash Current TWRP"
stuck in TWRP Recovery mode boot
did TWRP Wipe data (since required by installing the ROM)
stuck in Fastboot mode
it might have removed by mistake /system or /persist, I just did the default Wipe Data of TWRP
Device is correctly recognized with fastboot devices but I get this error when trying to boot with TWRP:
Code:
$ fastboot boot twrp-3.6.2_11-0-venus.img
Sending 'boot.img' (196608 KB) OKAY [ 4.999s]
Booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
fastboot: error: Command failed
Do you guys have any tip to recover the device? Any help very much appreciated
