Have you tried connecting the cameras as ONVIF devices to the NVR?
That can work without the 'language mismatch' error on the earlier camera firmware.
When i set it up before, changing the protocol from hikvision to custom resolve that error.

I don't remember if i tested ONVIF or not. It's been 2 years.

Because some of the NVR function is only useable with the HIKVISION protocol,
I needed to try the custom firmware in order to change the protocol without causing error.

I can use @montecrypto's hikpack 2.5 to unpack the R7 firmware, using r6 as the platform type. So I guess R6 and R7 platform must share the same encrypt key? But without any modification to the unpacked files, I got two warnings when repacking the firmware.

I haven't tried to update the re-packed firmware to camera yet, as I'm not sure if the uboot will verify signature of the firmware, I'm afraid to get it bricked

Bash:
./hikpack -t r6 -x digicap.dav -o output

так я хочу удалить веб компоненту совсем, чтобы уменьшить размер прошивки.
У вас получилось сломить прошивку и перешить камеру? у меня камеры DS-2CD2023G0-I, платформа G1 v.5.6.2build 191226, проблема отвязать её от Rostelecom. (Камеры, которые по распоряжению правительства вынуждены были купить у Ростелеком, причем за полную стоимость, для наблюдения за тем. чтобы все носили маски). Теперь Ростелеком не продлил контракт и порекомендовали просто выбросить камеры. Они даже не брендировали коробки.

Что дальше будет?
Чем мешает компонента?
Приветствую, need help, сослались на вас в другом месте, понимая, что вы в теме, спрошу у вас, быть может вы сможете подсказать как отучить камеры DS-2CD2023G0-I (платформа G1) от Ростелеком? (описания постом выше)
SADP камеру видит
nmap говорил следующее:
PORT STATE SERVICE
554/tcp open rtsp
7681/tcp open unknown
all other ports are filtered

Камеру переактивировал, ресетнул её без сети Internet, потом зашел SADP и сделал свой пароль, но как-то это мало помогает.

(UART-TTL модуль я потерял, новый пока не пришел), пока просто собираю информацию.

С G1 серией нет проблем возврата назад. Делалось такое спокойно из консоли возврат к оригиналу.

т.е. беру UART-TTL, прошивку оригинальную, загружаю на SD карту и обновляю?

Hi guys, i have a little problem with my ds-7608ni-k2 by getting complete root access

i used montecrypto's hikpack 2.5 to unpack successfully but unfortunately i can't manage to repack with the proper order the structure of the firmware. (i'm trying to substitute PSH restricted shell with the /bin/sh)

an original firmware comes like this :

Code:
Magic   : 484b5753
hdr_crc : 00004933 (OK)
lang_id : 00000001
date_hex: 20200320
devclass: 0000003d
File: headEx, CRC OK
File: uImage, CRC OK
File: start.sh, CRC OK
File: sys_app.tar.lzma, CRC OK
File: gui_res.tar.lzma, CRC OK
File: webs.tar.lzma, CRC OK
File: new_10.bin, CRC OK
=== Tail record:
File: new_20.bin, CRC OK
instead once i repack the firmware it becomes:

Code:
Magic   : 484b5753
hdr_crc : 00004202 (OK)
lang_id : 00000001
date_hex: 20200320
devclass: 0000002a
File: gui_res.tar.lzma, CRC OK
File: headEx, CRC OK
File: start.sh, CRC OK
File: sys_app.tar.lzma, CRC OK
File: uImage, CRC OK
File: webs.tar.lzma, CRC OK
=== Tail record:
File: new_20.bin, CRC OK
so essentially, for some reason it swaps the resources.

and i can see (via uart) that there's a problem exactly because of this. is there any way i can give the proper order while packing ?

or...
do you know if there's an easier way to achieve full root access to the nvr ?

What do you see exactly that shows this?

I suspect though that the real reason for the rejection of the modded firmware is the use of k41 instead of the needed k51 for the platform type.

Hey i tried both by passing -t k41 and -t k51 as argument in the hikpack tool but the result is essentially the same.

I'm trying to upload the firmware from the web interface ( is that correct ? or i have to do it in another way ? tftp or whatever, i don't know.)

this is what i get:

Code:

The platform type should be k51 so that the correct devClass is in the header.

What version of firmware is this?
And what version of firmware is running?
And what exactly did you modify?

I'm guessing it's around V4.40.xx
Around this point, that file name changed to gui_res.tar.gz

Ok, fine for the k51 but as i said unfortunately it didn't work neither.

regarding your questions:

Firmware version: V4.32.110 build 211009

I modified as i said the uImage file by changing the PSH with /bin/sh and trying to repack it

What are you saying regarding the new name it's a bit weird since when i extract it the name is actually gui_res.tar.lzma and not gui_res.tar.gz

when i do the packing if i delete the gui_res.tar.gz it successfully extract the file till there, so my guess is that as i said, i have the order swapped because it's expecting headEx as first instead i have gui_res.tar.lzma

EDIT

also by checking the logs while updating with the ORIGINAL firmware, the length of the gui_res.tar.lzma is correct.

OK, maybe that's a red herring. But odd.

Yes, you are right.
I didn't have the specific firmware you quoted, so was looking at a similar version from about the same time.
That file is nearly 3 times the size there, the firmware has been significantly restructured.
But I've now grabbed a copy of the version you quoted and the filesize is as your transcript shows, and I've unpacked it.

I modified as i said the uImage file by changing the PSH with /bin/sh and trying to repack it
I'm quite intrigued and impressed by this as it's quite a tricky and advanced thing to do.
The kernel itself is held in compressed form, then the root file system, in which /bin/psh resides, is held in cpio form.
So to get a usable modified result there are a few technical reversal hoops to jump through.
But check your 'Conversations' for a simpler and interesting alternative method.
