[Nubia Red Magic 3 Questions & Answers] kaizerv:
Done Fixing this

Actually, after trying that, I'm still stuck at around getting into the OS. Now, I finally managed to install back the CN version.

After some trials and errors, I try to summarize what I have been doing.

1. Found an easier way of creating system.img using system.new.dat using "Tool Unpack Repack DAT IMG v3 x64". Just convert system.new.dat.br using Brotli into system.new.dat, then throw that + system.transfer.list into input DAT, then it open the program to convert into system.img

2. Follow this cmd command by one of the guys that successfully unbrick his RM3 *At this point, I expect people to know things such as the twrp name should be changed according to command, you need to launch it at the same folder if you don't want to specify the path, etc, etc.

3.Now I'm still in the boot loop but pressing volume down + power, I can go to the bootloader and can flash and go inside twrp which previously I keep going into fastboot again and again.

fastboot flash recovery twrp.img

Enter the TWRP > Enable MTP or file transfer in the Mount data/otg/related folder> Put your "WhateverNameYourRom.zip" via OTG or PC into the phone. Probably need to unmount others except data & cache.

Install the .zip > clear Dalvik/Cache.

4.Reboot

5. If thing goes well, you be expecting the OS to start . If not, I think that's all the step that I took so far to make it work, so sorry if that can't help you.

*just realized the CN OS is full of bloatware. The seller really did me a favor by removing all that craps, then I just brought it back in full :crying:

Edit = I bricked again because I was messing with the system file. Just to be sure, I follow each step and success again. There's some extra thing that I do. Apparently, I used nubia recovery before going to TWRP. From there > Wipe Data > User Data > Wipe again > Cache. Then, flash twrp, n continue like usual.

If you have 0mB in Internal Storage, you need to go to TWRP > Wipe > Format > yes (Will incur the loss of data). Then repeat step 2 again.

Idk, if it's needed, I use "Universal DM-Verify, ForceEncryption" after the ROM flash.

- Just for some extra, rooting RM3S is the same way with RM3, but you need to manually install the MagiskManager.

- If you managed to enter the OS, created a full backup, so you won't end like me, and get f-ed twice with no support. No use crying over split milk

- One of the reasons I bricked my device again bcus I try to uninstall bloatware, which apparently, is not bloatware. So, folks, if it's in chinese, it doesn't mean it's not a system app. Backupx3

- All in all, I soft brick my phone 7 times in the course of two days. The first n second was hard because I didn't do any backup n all the steps randomly fail or work. The third till the seven was a breeze as I just restored back the backup. Uninstalling the stock browser from the system app also causes a boot loop which is kinda weird, n there's also two non-system chinese apps that will boot loop if you try to remove them via root uninstaller or something similar. Anything that can be uninstall normally after root won't cause a problem.

Best Regards
