Unfortunately, I can not unlock my Boodloader because I never had root on it, I can only open it temporarily via oem_unlock.

Does the recovery.img and boot.img need a system.img? Normally a recovery system has to work without an operating system otherwise it makes no sense.
[Nubia Red Magic 3 Questions & Answers] tr4657:
how did u fix it?
[Nubia Red Magic 3 Questions & Answers] ExVitamiN:
Nope, as long as I do not get the recovery.img and boot.img the v2.09 there will probably be no other way to bring the RM3 back to life.
[Nubia Red Magic 3 Questions & Answers] em902566:
You can by flashing the hall images file in the zip folder

Download any rom with zip file

Extract it

You will fine system.new.tar something like this

how did you fixed it?
[Nubia Red Magic 3 Questions & Answers] ExVitamiN:
I did everything without success.

Have synonymous over my second RM3 with V2.09 and root backups of recovery, img system.img and boot.img created and tried to record, but has not helped anything although the last version was the v2.09.

Now I am finished with my ideas

can it be that the recovery system is so badly damaged that it does not work anymore?

Edit:

I noticed now when I install different system.img and boot.img the counter in fastboot is set to 1, but when I install the system.img V2.07 and the boot.img V2.09 the counter is in fastboot back to 0. That means for me that the two images must be the right ones that do not trigger the counter.
[Nubia Red Magic 3 Questions & Answers] SuperDroidMe:
Literally by commands "fastboot flashing lock" and "fastboot flashing unlock"....on unlock device automatically kicked off system cleanup and repair. Then I figured what the hell and wiped data and cache in recovery and flashed NA Global 1.15 with bootloader unlocked. Which was convenient cause I restored Google backup then installed Magisk, patched boot.img and flashed.
[Nubia Red Magic 3 Questions & Answers] thel'vadam:
The image u attached is very low res.

Do one thing.

And this is for all

Step by step

Download latest Chinese rom.

Then format a usb c otg pend drive with fat 32 on pc and put the rom on the pen drive.

Open the Chinese rom on your pc.

Extract these files.

Vbmeta

Boot

Recovery

System

Modem

Etc etc as explained in this thread earlier.

Convert .br system file to .img using software steps exp via Google.

Flash these via usbc cable.

With usb drivera to the c port installed on pc.

The flash unlock command wont work.

Although u can install recovery.

Flash vbmeta first.

Then other. Files.

Flash recovery at the last.

Try both methods.

Reboot via cmd

And manual reboot via phone s dumb fastboot

Then try entering recovery.

Hope this time it works for you.

First of all, big thanks for the support.

In your other thread you flash the vbmeta.img and the dtbo.img into the system, is that correct or have to be flashed in vbmeta and dtbo?

So

fastboot flash system vbmeta.img

fastboot flash system dtbo.img

or so

fastboot flash vbmet vbmeta.img

fastboot flash dtbo dtbo.img
[Nubia Red Magic 3 Questions & Answers] thel'vadam:

[Nubia Red Magic 3 Questions & Answers] thel'vadam:
Exactly u need to clear cache and user data. Search Google for fastboot command for that.

Rest all process is fine.

If cache clear and usr data clear still produces no result.

Repeat the process again

If no result again

Try a different laptop.

That worker for me

Different laptop i mean.

Sometimes USB C drivers and adb drivers are the issue.

Also try on usb 2.0

---------- Post added at 08:28 PM ---------- Previous post was at 08:27 PM ----------

There may be another problem.

My phone had indian rom initially

I flashed chinese which gave me the loop.

In case u got global and u tried for global.

We need to get that sorted out

I believe that the system image needs to be of the same rom variant which u tried to flaah, the variant which gave u loop..
[Nubia Red Magic 3 Questions & Answers] ExVitamiN:
Summary:

I have now done all the steps again several times with the 1.15, 2.07, 2.09, 2.27 and 2.30, always with fastboot -w at the end anyway without success.

After flashing I let the RM3 start at least 5 times

and it s.PC and laptop with different usb cables tried. After the reboot, I always briefly see the RM logo then immediately the error message.

when flashing itself there are no errors.

Review:

Before the RM crash I was on the CN2.30 have made an update to EU2.07 but then no wipe cache performed because it started anyway, then I have installed the EU OTA 2.09 and after the restart started the error.

I am with my nerves at the end :)

my executed commands:

fastboot oem nubia_unlock NUBIA_NX629J

fastboot flash vbmeta vbmeta.img

fastboot flash dsp dspso.bin

fastboot flash splash splash.img

fastboot flash modem NON-HLOS.bin

fastboot flash boot boot.img

fastboot flash dtbo dtbo.img

fastboot flash system system.img

fastboot flash recovery recovery.img

fastboot -w

Try this

Fastboot flash parameter parameter.img

Fastboot reboot

You will go to your fastboot screen you will notice your numbers will rest to 0 or 1

This will not work, because you have to unlock the bootloader in the developer menu and since I can not start the operating system, this option is not for me in question.

Download the same EU rom which you tried to flaah the which gave u loops.

Then flash the vbmeta system boot of that zip rom.

Clear cache and user data at the beginning.

For the final step ehen u flash recovery . First try the eu zip recovery.

Then try the Chinese zip recovery.

[Nubia Red Magic 3 Questions & Answers] ExVitamiN:
Hello,

I finally made it and I'm happy.

It was not the USB cable or port, but ADB itself.

The problem was that I only had a minimal version of adb which did not show me any errors, any copying process via fastboot was okey but that was not true. when I installed the right sdk from here: "https://developer.android.com/studio/releases/platform-tools.html" I got an error copying the system.img. I had to customize it with the command "fastboot flash -S 500M system system.img" for a clean copy operation. After copying, the RM3 started directly without problems and I was able to flashing into the Recovery menu.

I would like to thank all of you again for the patience and support, without you I would not have managed.

I'm hoping someone can help me. I've followed the fix on earlier pages and used the files including system.img a user uploaded.

Now when booting my phone I get a device is corrupt and cannot be trusted message. I read somewhere else that the command 'Fastboot flashing unlock' may solve this but I get an error message.

Would really appreciate some help, maybe I've done something wrong but I've followed the instructions and used the files an xda user uploaded.

hi i've same your problem can u help me
[Nubia Red Magic 3 Questions & Answers] kaizerv:
Finally fix this

I swear if I ever fix this, I'm gonna post a solution. So, here we are. (Error device is corrupt and untrusted)

Bought RM3S from China two weeks ago, don't have a thread now, the phone even comes out tomorrow lol, stumbles here, and can somehow root my phone n all that good stuff. Then, I f-ed up, installing RM3 ROM into RM3S, big mistake I know, somehow I thought it works out. It happens like what some of you experience, non-stop nubia splash screen and looping again n again to fast boot. >> some of the users solve this by going lock>unlock>flash but not for me.

So, after grinding through websites & threads, I concluded one thing. It's the system.img. << this is the one that corrupted and somehow you need to replace it. Then, you look into the rom < there's no system.img. After digging, the system file is somehow related to the file "system.new.dat.br"

So, what you need is to change that ^ into "system.img". To do that, we need to have two things.

*Be warned, don't make mistake like I do, and ensure your rom is correct*

1. You need to have "Brotli", just google it. If you do it right, it will change "system.new.dat.br" into "system.new.dat"

2. Then, you need "sdat2img.py", google it > this thing need some python 2.7+ > and you also need another thing called system.transfer.list from the same rom which add with system.new.dat become output as system.img

3. Then, come to the second problem, the flashing of system.img, the system.img is huge, and your old fastboot will have an error. Go google some latest 2019 adb + fastboot and replaced with your old one. That solved the problem. It will have some magic header warning, but the transfer won't have an error.

4. Reboot, and enjoy your phone escape the boot loop and infinite splash. At least, that what happened to mine. You can flash back twrp and enter it recovery as it meant to be.

I know it's a rough guide, but hey, I hope it help some people out there.

Hi guys,

I just got stuck in fastboot mode. But then I read each and every one of your posts and now I'm free. I want to share it for you. Let's start

1. The first you must have an adb directory

2. Go to ui.nubia.cn to download the latest rom. Then open the downloaded rom and copy the files boot.img and recovery.img into the adb directory.The purpose of doing this is to get boot.img and recovery.img clean

3. Of course, this time your computer is in fastboot mode, you proceed with the following commands in cmd

fastboot device

fastboot oem nubia_unlock NUBIA_NX629J

fastboot -w

fastboot erase recovery

fastboot flashboot boot boot.img

fastboot flash recovery recovery.img

""After this step, do not flash file twrp . You need to reboot, you will exit fastboot mode.""

^^ you can try,If you haven't done it yet, please let me know.
[Nubia Red Magic 3 Questions & Answers] kaizerv:
Like I said, if your fastboot been boot loop at fast boot, U need to flash back the system.img. Use the rm3s rom, not rm3, which got me screwed on the first place. Its on the nubia cn support site. Extract the rom out, n follow the step on my previous post. U need to have at least the basic down, like all how to TWRP n shets. But try flashing the recovery n boot first n try again to boot to recovery, if its in fastboot to fastboot loop again, then u f-ed n need to get ur hand dirty to get the system.img. Anyway, be specific, like which step u done n where u stuck?
