MJSXJ05CM downgrade from 3.5.1_0052

[jordancadel]

Hi guys,

I tried to downgrade my MJSXJ05CM camera from 3.5.1_0052 to 3.4.2_0062 firmware but it didn't work.
The tf_recovery.img that I used was the one which can be found at https://github.com/cmiguelcabral/mjsxj05cm-hacks
My microSD card is a Sandisk Class 10 64Go formatted in FAT32.

When I plug the camera with the micro SD in it, the LED lights yellow but turn blue after few seconds.

Did any of you succeed ? If so, would you please tell me which microSD and recovery file you were working on ?

Thanks in advance !

Hi! I have the same problem, it's as if my SD card was ignored by the camera.

if you downgrade is not working, then use the hack-files from here (do not need downgrade from 3.5.1_0052) : https://github.com/zry98/MJSXJ05CM-hacks
an alternative would be using the hack from nickbel (do not need downgrade from 3.5.1_0052) : https://www.nickbel.com/2020/11/09/xiaomi-mi-smart-camera-360-1080p-sobstvennaya-proshivka.html#cut

what i did everytime before i have put in the SD Card with hack files on it:
bringing the device back to factory standards by using the "unbrick" tf_recovery.img (https://drive.google.com/file/d/1ve6XlBEiZebJV6ukJ0Oiu7DePw2JCsWj/view) and disconnect it from the xiaomi app.
Basically i know my device is ready to be hacked when the device is in the state of and shouting :" Waiting for connection".

Thank you for all these tips! I looked at the nickbel hack page. I do all the procedure indicated but when I put on the SD card and then I start the camera. The camera does not boot the hack, I waited 30 minutes for the led to turn blue but the led still flashes orange.

The camera remains stuck on "waiting for connection"

was the same for me. i do not think you will get a videostream over ONVIF, i only used it to control the cameras motor. i got a videostream via rtsp://:8554/mainstream only. (maybe "substream" instead of "mainstream" works too.

sorry have no time right now to do the nickbel procedure again. i could do it tomorrow and provide more information. but for now some thoughts (maybe you already did/follow these points, just asking to be sure):

• is your SD Card FAT formated?
• try to use SD Card with 16 GB max
• did you disconnect your camera from the app?
• did you "reset" your camera with the tf_recovery.img?
• is your default manifacture firmware 3.5.1_0052?
• did you put the "manu_test" folder on the cards root directory?
• are you using the MJSXJ05CM camera?

[GaetanPTX]

Hello, thank you for your answer, here are the answers to your questions below

• The card is formatted in FAT 32
• I tried with a 64GB card and another 8GB card
• yes, the camera is disconnected from the application
• I can't downgrade the camera version, my version is 4.0.9_0426 (every time I start the downgrade procedure, my camera ignores the SD card and starts normally)
• How do I know the version of my default firmware?
• Yes, I put the contents of the manu_test folder in the SD card
• Yes, my camera model is: MJSXJ05CM

Thank you for your help

The difference between our setups is the firmware. Yours is 4.0.9_0426, mine is 3.5.1_0052. I didnt have to downgrade, you have to downgrade, but as far as i know it is only possible by dismantling the camera and use an spi flasher. I am still waiting for my flasher module i have ordered on amazon (cause i wanna go even lower than 3.5.1_0052) so i can not provide a lot information on this. please check out maybe this: https://gist.github.com/belkone/fb63376a9b6b6ebe969e9c8f96c0defb

Hi guys, I have tried everything you say and there is no way it works. I haven't tried the nickbel hack as I wanted to keep using my home. My current status with or without sd is the same. It turns on with the yellow led and after a while it turns blue and moves the motors. It doesn't play any audio, I tried changing the speaker, but it doesn't respond with a new one either. When trying to configure with the app it never scans the code on the screen (I also tried to print it and nothing). I have checked that the usb connector is a bit burnt, but when I connect the motors and the led they work. Any ideas ?
