Flash the global rom of Note Air 3 on NoteX3 chinese version

[jsukwon]

Hello everyone,
I have a Note X3 and would like to flash the rom of Note Air 3 on it (same specs) for multi languge and the free library. From other topics, I guess I have to flash a custom recovery to flash the rom. Could you guys help? TIA

For the NoteAir3 there is currently a full and an incremental update.

You will need to do the full update using custom recovery and a flash drive.

The incremental update should not be done using recovery.
You can either "Check for updates" in the Onyx settings or download update.upx, adb push it still encrypted on /sdcard/ then kick it to update.

Ok i have downloaded and decrypted the full upx to update.zip. I have also made backup of x3 using these

edl /lgoco7.bin
edl /u0 /r backup0.img
edl /u1 /r backup1.img
edl /u2 /r backup2.img
edl /u3 /r backup3.img
edl /u4 /r backup4.img
edl /u5 /r backup5.img

It created 5 images that total 64gb, so I think it works. Just wonder how can i flash these back to it if things go wrong

Pretty much the same way that you backed them up:

edl /lgoco7.bin
edl /u0 /w /s0 /c0 backup0.img
edl /u1 /w /s0 /c0 backup1.img
edl /u2 /w /s0 /c0 backup2.img
edl /u3 /w /s0 /c0 backup3.img
edl /u4 /w /s0 /c0 backup4.img
edl /u5 /w /s0 /c0 backup5.img
edl /z

Just don't "factory reset" or "wipe userdata" at any time as this deletes the hidden userdata decryption keys.

Hi Renate. I got your message and custom rec
I flash the custom recovery to both rec a and b, after that reboot to recovery

edl /u /w /precovery_a rec.img 
edl /u /w /precovery_b rec.img 
edl /z
adb reboot recovery

The screen show blank on reboot.

adb shell
#id
.....
#start autoupdate

The text is right up, waiting for drive. It's all done now.
I format the data to make sure everything ok. It can be updated through ota to the latest 4.0.2 of Air3.
Im testing the device now to see if there's any incompatibility

Hi, I own a Note X3 Pro and I’m interested in flashing a compatible global ROM for this model. I saw that you successfully flashed the NA3 ROM on the Note X3 Pro. Have you experienced any issues while using it? Thanks!
