Bricked = camera will not turn on.
Is your camera bricked?
1. Reinstall firmware
2. Delete app from mobile device and reinstall, check SN.
3. Install camera app on mobile device of a friend or relative, pair with camera,
check SN.
4. Return camera to seller for refund or replacement,

<Edit: I see you are being helped in the "Bricked" thread...>

after i do unbrick with elf. it run normally.
but after a few minutes i used it.
suddenly it is bricked again then soundly beep beep make me crazy and the camera error (cant capture image or turn off and wifi direct disconnect from mobile ).

i minded this is happen because the fw is different with revision on camera.
this is just my opinion
everytime i googling to find fw version 1.0.0 22L, maybe it can change the SN, because the size is bigger than new version

as i already told you, no official firmware will change serial number. You need full .elf dump from someone with real 22L & even then you will have most probably his serial. So unless you made a backup first or you edit the .elf file, your serial number is gone for good...

 

[uchix]

so sad.
i have friend real with 22L.
but i don't what i should do after that.
and i don't know how to make a backup the .elf.
this make me crazy. because in indonesian nothing service center for xiaomi yi.
i already asked to xiaomi indonesia official.

the app that you used to upload the elf to the cam should be able to download it from his. Very similar way, only instead of uploading you will choose something like download.

i try feature upload on my xiaoyi, i afraid do it to my friend's xiaoyi.
but i dont get any file elf.

 

[jokiin]

you can't just extract an elf file from the camera like that, can be done via a script on most Ambarella models

 

[uchix]

OMG, i must using script.
i was very stupid about script.
>.<

Congratulations! And I thought your goose was cooked.

@uchix: That's VERY GOOD piece of work !!! Is it permanent? IE does it stay there even after reboot when you remove this script ?

So how I must install it?? I create a file document and copy this, then rename to autoexec.ash and put it in the sd card and turn on but it still same serial number
