Issue installing firmware on RA82 AX3000 INT #5

Closed jackmeehan closed 11 months ago

jackmeehan commented 1 year ago

Thanks to @remittor for fixing the issue with reading device info from the RA82 so quickly!

The exploit now runs, the script can retrieve the device info, however I'm still having trouble installing firmware.

My router is currently on stock v1.4.21 and I am trying to downgrade to stock v1.3.27 (rx power issues on 1.4.21). I get the following output from the tool:

Detect valid SSH server on port 22 (auth OK) Image files in directory "firmware/": "firmware/factory.bin" Download file: "/tmp/dmesg.log" .... Download file: "/tmp/mtd_list.txt" .... Download file: "/tmp/kcmdline.log" ....

ERROR: Kernel data not found!

I have tried installing v1.4.21 also and get the same error. I'm wondering if there is anything extra I need to do in order to successfully flash the RA82 or if it's just not possible?

Thanks in advance.

I have looked at the contents of the image you are trying to flash. I have not done support for installing such images yet. I don't have a device that requires such images.

Thanks v much for replying and looking into it. With some modifications (with the help of Code Interpreter) I have gotten it as far as the RootFS check but got stuck there.

Are you aware of any other tools that might help downgrade the stock firmware? Firmware Mod Kit and Binwalk don’t recognise the file system

Thanks v much for updating. (FYI: there's a typo on line 205 of gateway.py ["foarmat"])

Unfortunately the tool still doesn't recognise the file system of stock firmware (I tried v1.3.27 and 1.4.21) - resulting in:

Detect valid SSH server on port 22 (auth OK) Image files in directory "firmware/": "firmware/miwifi_ra82_all_7eb36_1.3.27_INT.bin" Download file: "/tmp/dmesg.log" .... Download file: "/tmp/mtd_list.txt" .... Download file: "/tmp/kcmdline.log" ....

ERROR: Kernel data not found!

1.3.27 is the version I'm trying to install. I have attached both 1.3.27 and 1.4.21 firmware files here in case you don't have access to them. I've also attached the "output" dir in case there is anything useful to help debug.

Thanks again!

firmware outdir.zip (I have included full_info.txt)

@ScotchTartan , Your source code is not the latest

@ScotchTartan , Your source code is not the latest

I tried using latest firmware (miwifi_ra82_firmware_722ce_1.4.21_INT.bin) and previus (miwifi_ra82_all_7eb36_1.3.27_INT.bin) I cloned the latest git repository, i'm sure because latest commits are included.

What do you mean with source code? which one?

Thx

Seems AX3000 has the bootloader locked?

It works, flashed OK.

Thx

jackmeehan commented 11 months ago

@remittor thanks for updates - stock firmware files now flash successfully to RA82!

However, I still get the below error when trying to install Breed:

@ScotchTartan did you manage to get Breed installed successfully? If so, how?

Thanks

No, as far as i know, the bootloader (uboot) of this device is locked. By the way, last stable image for RA82 is 1.4.31, but nobody dumped it.

When i flashed it, i can install any stock image version with permanent ssh access, but the advanced configuration is still blocked because the accessed GUI is the same. In the video published on YouTube you can access the original Luci gui with all the available configurations, unfortunately with ra82 i didn't. It's fine for downgrade firmware, if you are suffering performance drops as many users reported. I'm not a master of OpenWrt, so remittor has the key for this device :1st_place_medal:
