I try to install Gcam but when I enter to Fastboot with botons , it doesnt enter , is black screen but is on , the pc recognize my Phone , is the a2 64gb 4ram , is new

You can flash the splash image from the factory image to fix that.
Code:
fastboot flash splash splash.img

There is a tutorial le somothing??

May be fastboot flash splash splash.img from stock image would fix this.

HELP Mi Mix 6/256 doesn't start

My Mi MIx doesn't start.
When I try to turn on it, the screen only shows the MI logo and under it the text 'unlocked'.
I can log into the fastboot mode and I can flash the recovery and I can log into the recovery mode, in fact I can change the recovery
using the fastboot modality. I tried to use the 'XiaomiFlash.exe' to flash a FASTBOOT ROM, but I always see the error 'Flash xbl error'.
(I think It could be easy if I could copy and paste the ROM.zip into the device and if I could use the recovery to flash the ROM.)
I need help, very much help. thanks

I resolved

I have a soft rocked Red Magic 3

Can anyone tell me what this (remote: Flashing is not allowed in Lock State).
What exactly is locked? Is my cell OEM unlocked?
I flashed the wrong TWRP (for the 2017 Red Magic-NX209J) and even though I have been able to unlock my cell via CMD commands; it remains permanently in fastboot mode?
If I send a CMD command to reboot it reboots straight back to fastboot mode.
No form of ADB connect seems to work an my windows PC cannot see/show the cell?
How the hell do I fix this? It's been in this state for a week.
Can anyone help?
Meaby try this?
Then, to unlock your bootloader, enter "fastboot oem nubia_unlock NUBIA_NX629J"
And meaby try the recovery backup instead of TWRP.

Thanks for the suggestion. I have no recovery back up Is it possible to get past TWRP being locked and use CMD to flash the International or chinese ROM? Or recovery image?
Unless tools are developed to unbrick this device I am scared this problem might be permanent
Download this twrp, and then upload it to google drive or something so the rest of us can download it too .

Thanks but what do i do with it? Its all in an asain language?
Link not open bro
The TWRP does not work
Sorry. That link to the twrp does not result in a bootable twrp recovery for me.
I am starting to think my cell is not fixable.
I did not do that much wrong I just flashed the twrp for 2 models of red magic earlier. It only has a fastboot mode. I either get a boot screen then fastboot mode or a warning about the bootloader being unlocked.
Whatever is wrong with my cell prevents ADB connect an the cell is not able to be seen by windows.
This $1100 New Zealand dollar cellphone may be permanently bricked by my mistake.
I might just need to bin it an buy another one.
Lesson learned.
It confusing....
My cell acts like it has a softbrick (can turn off an on an has fastboot options and I have erased it an OEm an bootloader unlocked it)
And also behaves like a hard brick (resists every method of repair).
I just do not understand it or Nubia products. I am unfamiliar with this phone.
Does anyone have any clue how I can see this cell on my windows pc or ADB connect it an boot into TWRP?
Are there any Nubia repair software tools?

Thanks for that. I'm talking about using CMD to totally wipe everything in the cell an reflash the Chinese ROM that came with it. Repair software. Might take months to develop software like that.

Also it isn't a zip. It's some other kind of file. And does not boot into TWRP on my unit
So are you able to unlock your bootloader in its current state?
If you have an older TWRP installed maybe try changing the model on your bootloader command to match it:
fastboot oem nubia_unlock NUBIA_NX209J
If this works then flash the correct TWRP and the boot IMG from your original rom
fastboot flash recovery <new recovery>
fastboot reboot bootloader

Terrapin. Absolutely nothing worked. I am the 3rd person who has had this issue I know of. 2 other xda members had the same issue. One with TWRP like me an the other got stuck in fastboot mode after trying g to flash an apk of Gapps? I think these cells do not like tinkering. But your advice enabled me to be OEM and bootloader unlocked. But always.....straight back to fastboot mode no matter what I flash? My red magic 3 device is currently at a service center with a technician trying to solve the problem. I have 3 repayments left on my Xiaomi Mi9 that has zero flashing issues. O admit i.may be ignorant of the ways of Nubia ?
I did it

enter recovery, use a FAT32 pendrive format, add Chinese ROM, rename it (update.zip) to OTG flash.
Everything works again.
good luck.

Thank God. Maybe the Chinese service guy I'm paying will get on xda an try your idea. I'm being lazy saying that lol. Thanks very very much. I will show your post to the service guy who has my red magic 3 or try it myself.
There's no way your a junior member working all this out. I'm a junior member listed as a senior member who makes rookie flashing errors with Chinese cellphones lol.
I will share if I can implement your ideas successfully. Thanks buddy my missus really loved this phone I felt really bad when I incapacitated it.
Fingers crossed.....
I have no idea how did you managed to flash the system.img
C:\adb>fastboot flash system system.img
target reported max download size of 805306368 bytes
Invalid sparse file format at header magi
LE: After this error, somehow it manages to continue and flash all partitions of the system, but after above tutorial, the phone still reboots in fastboot mode and cannot access recovery

Thanks for the help. I do not understand some of the commands an cannot seem to get them right? And I do not understand why the instructions say to cmd flash the image (IMG) via command prompt (which just errors like the strange NON-HLOS command?) Then the instructions say to flash the Chinese rom via otg?
Are you supposed to flash the ROM twice?
Can someone please give me some more detailed instructions as this cell has been non functional about 2 months now.
Planning to fix it an give it to my partner

My suggestions is, download a full sd card update package, unlock the bootloader temporarily,extract the update file and flash the vbmeta.img to vbmeta partion, then flash the recovery.img to recovery partition, after that, try to boot into recovery through bootloader. You have to make sure that you use all the same file from same package, if you are use a low version vbmeta file to boot a high version system (or recovery ) it will not boot. the vbmeta is very important on this phone.

My device is not bricked. And even doing these steps by fastboot does not install recovery. He gets the black screen. And then I press the power button and it restarts normally, but without having the custom recovery installed. Do I need vbmeta patched? I have this installed miui_LIMEGlobal_V12.0.16.0.QJQMIXM_ae9abfb546_10.0 and it extracts vbmeta to do these steps but with no effect
