Smart Solar IP Camera v4.0.117 #14

Open BmdOnline opened 1 month ago

BmdOnline commented 1 month ago

I'm trying to customize this model. 3203968_8712879161370-111_01_20240318114817_s

Connecting with Tuya Smart, the camera is v4.0.117. An upgrade to v4.0.120 is suggested. I don't install it.

What I've tried, without success :

Each time, only 6668 port is opened :

$ nmap -p- 192.168.0.155 Starting Nmap 7.94 ( https://nmap.org ) at 2024-05-20 00:26 CEST Nmap scan report for 192.168.0.155 Host is up (0.041s latency). Not shown: 65534 closed tcp ports (conn-refused) PORT STATE SERVICE 6668/tcp open irc

Nmap done: 1 IP address (1 host up) scanned in 13.59 seconds

I'm using a Sandisk 64Gb, FAT32 MicroSD. Each time "DCIM" folder is created on the card, so it doesn't seem to be related to the card.

I don't know what else to do for the moment. I will try to open the camera, but I don't know how to do without damaging it.

I've successfully opened the cam. We have two sets of GND/TX/RX pins. I've checked they're not linked. I will try both of them and see what happens.

BmdOnline commented 1 month ago

I got results with the GND/RX/TX on the bottom left.

mihovilkolaric commented 1 month ago

Hi,

I am fighting with the same device, also without any success so far, also only port 6668:

Nmap scan report for 10.42.0.240
Host is up (0.045s latency).
Not shown: 999 closed ports
PORT     STATE SERVICE
6668/tcp open  irc

I performed the update to 4.0.120 (as I had issues on my WIFI on 4.0.117, and also could not convince the camera to record to the MicroSD-Card) - but the update did neither help with those issues, nor it changed anything in regards to the rooting-options I tried so far.

After the update, I found an update.bin on the Micro-SD: update.bin.zip but could not find anything useful yet (using binwalk).

So far I tried:

Unfortunately, I have no programmer, so I can't provide any flash-dump.

Any other hints how I could further analyze?

mihovilkolaric commented 1 month ago

BTW: placing a file _ak39_factory.ini on the SD-Card does not lead to the effect described in https://github.com/guino/Merkury1080P/issues/42#issuecomment-1278036051 .

BmdOnline commented 1 month ago

I've ordered a CH341A programmer, I will try to dump the firmware when I receive it. Without desoldering the chip (like this) if it works.

mihovilkolaric commented 1 month ago

I might give it a try with an arduino - but I have no clue yet how to open the camera without damaging it. Do you have any hints?

BmdOnline commented 1 month ago

Remove the screw near of SD Card. Then pull gently around the front of the camera. Use a thin accessory that won't scratch. Possibly with your fingernails 😉 The black side should start to emerge from the white frame. Watch out for the cable used to connect the speaker.

guino commented 1 month ago

@mihovilkolaric the update file you posted seems to have 'part' of the root file system, but it doesn't seem to include the main application running on the device, settings or startup scripts. So there's not much we can do with it. If you do get a full flash dump I can take a look when I have a chance.

Getting into the bootloader should just be a matter of powering on (or power cycling) the device while you're connected to the RX/TX pins and pressing a key to stop the boot process and enter the bootloader. Many devices do have this disabled (it will boot no matter what you press), others have a password (it will ask for a password when you press something), and others just go right into the bootloader -- only way to know is trying.

BmdOnline commented 1 month ago

When I press any key, I can interact but mixed with log output. It's difficult to deal with it. I have to keep camera connected to tuya to prevent it to suspend.

I will receive CH341A programmer soon. I hope I can dump flash without desoldering.

guino commented 1 month ago

I emailed you with information based on the log you provided, but just for future reference (to anyone else looking at this issue), the logs seem to indicate that this camera is not running Linux, likely it is running RTOS, meaning:a hardware programmer is the only option to make any modifications, and they would be very time consuming and limited to what's already compiled in the main application.

BmdOnline commented 1 month ago

I have received my CH341A programmer and dumped entire flash : (link removed due to privacy data stored in the flash. sorry)

mihovilkolaric commented 1 month ago

@BmdOnline glad to read that you managed to get a flash-dump! (I tried with flashrom on a raspberry pi, but as I have no SOP8-Clip (and bad soldering skills), the results were not stable/reproducible).

However, also with your dump, binwalk seems to recognize a lot of linux-related stuff, but - as for the update.bin posted earlier, it fails to extract a "full" root-filesystem.

@guino with this new information given - do you still think it is RTOS, or are the chances that it is a linux? The few extracted files at least look like linux ELF-binaries:

@mihovilkolaric, I've removed my dump because it contains privacy data in it. 😞 @guino, I can mail you access to the dump.

mihovilkolaric commented 1 month ago

Good news!

Unblob succeeded in extracting the root-filesystem. app_init.sh looks promising.

Short update: The camera executes a shellscript called other.sh when it is placed on the root-folder of the MicroSD-card. With the path /tmp/mnt/sdcard/ you can access the SD-Card itself, and copy stuff from the "running filesystem" to the card.

E.g. the /etc/shadow looks like this:

root:dY6MT354.O2K.:0:0:root:/:/bin/sh
guino commented 1 month ago

@mihovilkolaric did you try to start a telnet server from that other.sh script ? may need to put a mips busybox on the SD card to try and run telnetd from it.

guino commented 1 month ago

@BmdOnline @guino with this new information given - do you still think it is RTOS, or are the chances that it is a linux? The few extracted files at least look like linux ELF-binaries:

The logs I had sees didn't show anything indicating linux but the dump seems to show it's linux, I asked @BmdOnline for a copy of the dump so I can take a look too.

mihovilkolaric commented 1 month ago

@guino yes, I was able to start a telnetd (at least according to ps and netstat). But until now I did all my tests with a factory-reset camera, so I could not try to connect. This is the script I used: other.sh.txt And this is the output it produced: myhack.log.txt (needed to rename both files to .txt as github neither allows .sh, nor .log)

Next step it to connect my cam to a WIFI, and see whether telnetd still starts.

BmdOnline commented 1 month ago

I asked @BmdOnline for a copy of the dump so I can take a look too.

@guino I send you a link today. Have you received it ?

mihovilkolaric commented 1 month ago

@guino , @BmdOnline : Also after connecting to WIFI, the other.sh is executed. So I replaced /etc/passwd and /etc/shadow with a version containing the hash from https://github.com/guino/LSCOutdoor1080P?tab=readme-ov-file#root-access and afterwards start telnetd.

The first two connection-attempts with user root password telnet did not work (camera closed the connection)

$ telnet 10.0.0.9
Trying 10.0.0.9...
Connected to 10.0.0.9.
Escape character is '^]'.

Zeratul login: root
Password: Connection closed by foreign host.

but then it worked:

$ telnet 10.0.0.9
Trying 10.0.0.9...
Connected to 10.0.0.9.
Escape character is '^]'.

Zeratul login: root
Password: 
Hello Zeratul!
[root@Zeratul:~]#

So, the camera is now rooted!

BmdOnline commented 1 month ago

Can you provide a working package ?

mihovilkolaric commented 1 month ago

Sure. Extract root_v1.zip to the SD-card, and boot with the card inserted.

mihovilkolaric commented 1 month ago

Now that we have root-access - does anyone know how to enable motion-detection + recording to SD-Card? (This is actually the reason why I started the investigation).

I guess it has to do with this files:

[root@Zeratul:tuya]# cat tuya_sd_record_on_off
1[root@Zeratul:tuya]# cat tuya_sd_record_mode
0[root@Zeratul:tuya]#

but changing them has no effect, and after a reboot there are reset to the default.

BmdOnline commented 1 month ago

And how to enable rtsp stream...

BmdOnline commented 1 month ago

@mihovilkolaric, I'm trying to reproduce your work, but I'm not familiar to binwalk and unblob How are you extracting the root partition :

5844396       0x592DAC        ASCII cpio archive (SVR4 with no CRC), file name: "root", file name length: "0x00000005", file size: "0x00000000"
mihovilkolaric commented 1 month ago

basically I just called $ unblob XMC.bin which outputs

and creates a directory XMC.bin_extract/ and a lot of sub-folders, one of it being the root-filesystem.

BmdOnline commented 1 month ago

Okay, I just have python issues. Will upgrade and try unblob.

BTW, root is working, but I have to keep camera connected (tuya app launched with camera preview) to prevent power sleep.

Thanks.

guino commented 1 month ago

@BmdOnline I have never seen any of the 'linux' devices sleep before, I have heard of the battery operated devices having an automatic sleep to reduce power consumption.

Are you guys able to execute anything like ls -laR / or ps -w to identify the main application file ?

gtxaspec commented 1 month ago

the platform you guys are working with is the Ingenic "Zeratul" battery platform, pretty common in the battery ip-cam world on the T series platforms... the way it works, theres typically an external MCU controlling power to the SoC, and reading motion input from something like a PIR sensor. When theres no motion, after a timeout the MCU will physically power down the SoC. Theres 2 different processor architectures built in to the SoC. RISC-V, and MIPS. The RISC-V core will perform sensor and ISP initialization as soon as motion is detected, while the linux core boots up, and then takes over.

Yes, it was something like this. When motion is detected (pir sensor) or if tuya app is streaming video, camera stays online. If not, it goes into deep sleep. Linux restarts on each motion detection, reconnect wifi, and so on.

@gtxaspec, how thingino-firmware can help ? @guino, I'm not sure you're receiving my emails ? Have you downloaded my flash dump ? I've mailed you a link yesterday.

gtxaspec commented 1 month ago

So far we don't support the battery powered zeratul platform, it's complex to support since each different vendor can and do use different microcontrollers in their respective designs. But we do have extensive documentation in case anyone wants to try and adapt and or create their own implementation.

I have no idea where this /stone/main comes from, resp. why it vanishes after starting ...

I can send you ls -laR tomorrow, when I have physical access to the SD-Card - but in yesterday's mail you can find a copy of most folders.

mihovilkolaric commented 1 month ago

@gtxaspec : that's interesting. Do you have any idea how the app is able to wake up the linux-core? Do MCU and linux-core share the same WIFI?

gtxaspec commented 1 month ago

in the designs we've seen, the microcontroller can be standalone, or built-in to the WiFi module, it depends on the design of the logic board.

its not so much of an "app" waking up the linux core, but the design of the firmware built into the soc.

  1. power on
  2. both cores start up
  3. risc-v starts up quick ( sub 300 ms )
  4. risc-v initializes ISP while the linux core boots.

@gtxaspec My question was not precise enough - I am wondering how mobile app can wake up and connect to the camera, even if it is in sleep mode.

In a wireshark-trace I could see that, even though the cam does not respond to pings (and the telnet-session times out), it still is able to send and receive MQTT - and looks like this is used to wake it up.

that one starts the applications alps and main, and afterwards deletes the "/stone"-folder. Unfortunately, both happens before other.sh is executed, so I can't dump its content before removal.

So, I have still no idea where the "stone"-folder comes from - I did not ind it in any of the mtdblocks. Maybe there is some other memory/flash (or even ROM) in the SoC?

@guino

Are you guys able to execute anything like ls -laR / or ps -w to identify the main application file ?

here it is: ls-laR.txt

btw: The camera has no ftpd on it. Where could I find a busybox for this device including ftpd?

@gtxaspec My question was not precise enough - I am wondering how mobile app can wake up and connect to the camera, even if it is in sleep mode.

In a wireshark-trace I could see that, even though the cam does not respond to pings (and the telnet-session times out), it still is able to send and receive MQTT - and looks like this is used to wake it up.

in the recommended hardware designs from ingenic, the wifi module can periodically check in at a predefined interval to the associated wifi A/P, while the linux portion is powered down.

Thx, that works!

Do you maybe also know how to prevent the linux from shutting down, and how to record the data from the camera?

BmdOnline commented 4 weeks ago

When we launch Tuya app (or LSC Smart Connect), the camera wakes up directly when connecting. Maybe Tuya app send a specific network command, like some wake-on-lan ? @mihovilkolaric, you don't see anything wiith Wireshark ?

the soc is physically powered down by external means, a standalone MCU or a combination WIFI/MCU. which wifi module does your unit have? do you have up close photos of the board?

I have extracted all partitions from camera

dd if=/dev/mtdblock0 of=/tmp/mnt/sdcard/mtdblock0
and so on...

Reading Partition Boot Analysis, and tag partition strings (see below) we have :

partition Size Designation
mtdblock0 256 Ko boot
mtdblock1 352 Ko tag
mtdblock2 5 Mo kernel
mtdblock3 6 Mo rootfs
mtdblock4 2.5 Mo recovery
mtdblock5 1.4 Mo system (squashfs)
mtdblock6 512 Ko config (jffs2)
mtdblock7 16 Mo all

tag partition contains some interesting parameters :

CMDLconsole=ttyS0,115200n8 mem=40M@0x0 rmem=24M@0x2800000 root=/dev/ram0 rw rdinit=/linuxrc mtdparts=jz_sfc:256K(boot),352K(tag),5M(kernel),6M(rootfs),2560K(recovery),1440K(system),512K(config),16M@0(all) lpj=6955008 quiet
FWIF"ZRT_release_202310261423_biao_ubuntu;[VERSION];ver=CAMERA_SOC_T31ZC_jxf37p_4.7.2_V;"

Camera soc is Ingenic T31ZC

Now we have to extract rootfs from mtdblock3. main process may be stored here.

The rootfs partition stores the root filesystem. rootfs is compressed with lzo and mounted through initrd. The initrd is similar to the initramfs method, and it is also a ramdisk, which is stored in the memory, so the files created or modified in the system only exist in the memory, and the content will be restored after the next startup.

Edit : Reading Quick Start Optimization The main program should be placed in the rootfs and loaded and run at the first time. For example, in rcS, you can run the main program after the environment variables are set.

Tried that (by copying /dev/mtdblock to the SD-Card using telnet), but neither unblob, nor binwalk were able to extract anything out of the dumped file. I am out of ideas right now.

BmdOnline commented 3 weeks ago

/dev/mtdblock3 contains compressed rootfs_camera.cpio file. We have to decompress it, not using binwalk, unblob or something like that, but finding right uncompress method. Claimed to be lzo. First bytes are “JZ

But I don't know how to decompress it.

The header should be corrected, look at it with a hexeditor. https://github.com/gtxaspec/wz_mini_hacks/issues/69#issuecomment-1463610002
