I can access some partitions with mtkclient and can write (brom mode):

Please close the thread or no answer (I'm new here, don't know how to delete), i fixed it by myself because God hint (believe it or not
).
To who have the same issue:
I copied the vbmeta.img from https://xiaomifirmwareupdater.com/miui/evergreen/stable/V12.5.9.0.RGBMIXM/ (the fastboot one) to mtkclient folder
and did python mtk w vbmeta_a vbmeta.img (after holding vol down + vol up).
Have a good day.

I will donate beer monet to 1st person who helps fix my phone!

I can't boot to CM Recovery 1.4.
But I can boot to the SPL (Three Skateboards with white Screen)
I have a white G1 specs are:
* 8GB ADATA SD Class 6
* Partioned at: 2GB EXT 2 32MB Swap Rest FAT32
* I am updated on the newest radio and the SPL.
* I am running Cyan 4.0.4
The Scenario:
I was playing COD5 on PS3. I went to Ifap.to on phone while it was on Wifi. So then I was trying to skip through the video and the phone obviously froze up and then it shut off and reboot itself. It never got past the T-Mobile G1 screen.
Then I tried to go to recovery by holding home + power and it doesn't work. So I held down power + camera and it goes to the three skateboards so I know I'm not bricked(not yet) What can be the issue and what would I have to do to fix this.
Please email me or post here whichever is convenient to you.
Thanks,
I WILL DONATE BEER MONEY TO 1ST PERSON WHO HELPS FIX MY DAMN PHONE!!
set up fastboot and fastboot flash one of your nandroids.
http://www.4shared.com/file/136452986/f9d297d5/nandroid-cm41111
if you don't have one (for some unknown reason) here is one i uploaded a while back to help some one who couldn't get their touch screen to work.
http://forum.xda-developers.com/showthread.php?t=532719
there is good thread to get fastboot/adb set up.
to restore you nandroid via fastboot
Code:
fastboot flash system system.img
fastboot flash userdata data.img
fastboot flash boot boot.img
fastboot reboot
those 3 images are the only ones you will need to restore via fastboot.
i suggest putting them in the folder that has fastboot.exe in it, and cd to that folder.
also since you say you have the new spl, i assume you mean 1.33.2005, then you will need the updated drivers found here (http://sapphire-port-dream.googlecode.com/files/usb_driver_updated.zip)
if you can't get all this set up then i suggest trying to apply the DREAIMG.nbh file in bootloader (screen with the androids)
you can get the DREAIMG.nbh file here (http://forum.xda-developers.com/showthread.php?t=563679). also you can use that guide as a resource to re-root your phone.

MihanickX's method of emergency flashing

This is a translation of MihanickX's post
Code:
h*tp://4pda.ru/forum/index.php?s=&showtopic=191005&view=findpost&p=5306386
It seems that some people were able to revive their phones using it, so it might be useful.
---
This will fix no boot logo problem after 2.1 update (maybe this method will also help to restore "dead" phones):
1. Install LG_Android_Driver Ver 1.0
Code:
h*tp://files.gameworld.kz/c5z46n1ukk.html
2. Download and extract KDZ_FW_UPD flasher
Code:
h*tp://forum.xda-developers.com/showthread.php?p=8655201
3. Download ROM (.kdz file) and place it in the flasher folder. You can find some ROMS in this thread:
Code:
h*tp://forum.xda-developers.com/showthread.php?t=802895
4. Press "volume down" key on the phone and connect usb cable.
5. Open Windows Device Manager and disable LGE Android USB Modem in device manager.

}
6. Run "KDZ_FW_UPD.exe" (run it as administrator if you are using Windows Vista/7).
7. Set "Type" to "3GQCT" and open your firmware file.
8. Set "PhoneMode" to "CS_EMERGENCY".
Some information about phones modes:
DIAG - standard flashing mode for phones which are turned on.
EMERGENCY - mode for flashing phones in Emergency (Download) Mode.
CS_EMERGENCY - same thing, but appears to be for non-working phones.
9. Press "Launch software update" to start update.
10. As soon as your phone turns off with sound and animation in the screen you can disconnect it (or continue waiting, but you only will get an error):
11. Now turn on the phone and do a hard reset (On the lock screen simultaneously press and hold the volume up, home and search buttons. After several seconds you will see hard reset dialog). If you want, you can now flash using "DIAG" mode.
Thanks a lot, very useful.
Thanks for this wonderful tip
i followed your guide and i get the LG screen (second one) and it just hangs there.
Any ideas?
Same problem....

install recovery using adb

Windows users should already have :
<<adb drivers>>

so u did root. u unlocked bootloader. u flashed a recovery and u installed a new rom. one day u start "digging" things to see if u can delete all the unwanted files so u make the phone faster and accidentally u deleted an important file and now it cant boot and it cant go into recovery. you are wondering what you CAN do now ! The answer is : Everything !
You can either go back to stock rom or
you can re-flash the recovery and then reinstall the rom.
1. Download the platform tools for your machine ( windows , linux or mac-os ). Here i have the adb fastboot for you.
2. Copy the recovery image to a location on your computer thats easier for you. The recovery image should have .img extension. If it is in a zip file, extract the .img file from it before proceeding.
3. Connect the phone to the pc and open cmd inside the fastboot folder you downloaded ( windows ). The others not on windows must use cd [path to their desktop,inside the platform tools where they see the adb file].
** If you are on a boot loop but the pc gets to recognize the phone even for a second then
4. Type
i) adb reboot-bootloader
ii) fastboot flash recovery recovery.img ( the command is: fastboot flash recovery [recovery image path/filename] )
5. When its done , reboot. Hold Volume down and power button to see if u get in recovery mode. :highfive:
Install the rom now the way you already know. There are many guides for that so i won't make a new.
cheers :good:
**Windows users can use this fastboot to unlock bootloader too. Lite fastboot commands guide provided here
**Linux users don't even need to download it , they can just directly download it from their terminal
I hope this thread helps a little those that dont know what to do when they delete an important file. *Pictures coming soon*

Use magisk to patch the boot image:
{

Connect the device to the PC via USB Cable.
Now transfer the patched boot file(magisk_patched.img) and vbmeta.img from your device to the platform-tools folder on your PC.
Inside the same folder, right-click on an empty area while pressing the ‘Shift’ key.
Select the option ‘Open PowerShell window here.
Or you could also head over to the platform-tools folder on your PC, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
Type in the below code to make sure the device is successfully connected (an alpha-numeric code suggests successful connection):
Code:
adb devices
Now type in the below code to boot your device to fastboot/bootloader mode:
Code:
adb reboot bootloader
Next, type the below code to flash the patched boot image file:
CSS:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash boot magisk_patched.img
fastboot reboot

Thanks to @ManshuTyagi for TWRP and @topjohnwu for Magisk
PS: I have tested this on only RMX 3031, and it may work on GT neo(CN) (RMX 3357) without any edits. If it works for you, please let me know, will update the post accordingly.
and how to update RUI 3 afterwards without a full wipe?
good day, any guide on how to obtain the Boot.img and vbmeta.img file

How to unbrick redmi 9C?

Hello,
I accidentally bricked my redmi 9C phone and now it just has a black screen and when I plug the phone into the computer, I get the error "Unknown usb device (Device descriptor request failed)". My goal is to bypass the device and then flash it to fastboot.
I think I installed all the drivers. Thanks in advance for your help
Same problem as mine, im unable to find a fix...
I am not from this device but have you tried emergency download mode.
