Hello community,
I'm gonna try build OpenWrt for a modem isn't supported rn.
OpenWrt supported modems are few and not common in Egypt (where I live).
ISPs limit functionality of their modems with the firmware being ONT ( It has their logo and custom things and so).
Unfortunately, the official firmware for this device isn't available online (ONT) but I found some firmware which maybe useful.

2) Is it possible to save the old/standard firmware already found in the router? For some reason, I was not able to download from ZTE or other website the standard firmware and I would like to keep the option of returning back, just in case.
To add, this version of H108N misses the USB port. The PCB appears to have the pins for the USB connector, however the box has no opening - the firmware is probably a modified version that excludes the related USB functionality.
Most likely not. The web interface of OEM firmware usually has some sort of a protection scheme that validates the file you are uploading for the flash operation. It checks the file checksum, or assumes that there's a file header somewhere with specific magic numbers that identify the file as a valid firmware image.
When these conditions are not met, the flash process will be aborted. If there's an image file in the OpenWRT downloads are for your router that has the name "factory" in it, then these images can be flashed through the OEM upgrade procedure as they have been masqueraded to look like OEM-provided firmwares.

Most Linux-based OEM-provided firmwares are running in a jailed environment where any access to the "root" user is prohibited. If this is true for your router, and the MTD device objects created by the kernel are protected so that only "root" can read from them, then there's no way in the Linux environment to read from them. You'd need to resort to a JTAG, or other low-level interface and read the data off the flash chip directly.
Sometimes it is possible to create an alternative firmware that can be run from RAM directly. You'd need a serial console access to the bootloader, interrupt the boot process and then find some way to upload your alternative RAM-based firmware into the router's memory before executing it. Then you'd essentially be running the firmware in "live" mode where you can access the hardware resources on the router, but your changes will not be persisted over power cycles. If you manage to build a suitable firmware image for your router and start it up, then you can read data from the MTD device objects and store them into a temporary file in the memory-based file system that the "live" image is using. Then start up a TFTP server and transfer the file away.
Hi, I recently got in my hands an old router. I was trying to update i'ts firmware, but the places where I can download the firmware, are a bit doggy, and I don't want to ruin my router. That's why I want to dump the flash memory, if in case something goes wrong, I can get it back to working conditions. The thing is the next. I'm a noob at programming with Arduino, so I need the help of someone, that knows about this. I've been searching a bit, and AFAIK, the only necessary things are that, the flash chip that you are trying to dump, must have an SPI interface and you MUST remove the chip from the board before working on it. I know that my flash chip has a SPI interface (in the datasheet it says "The MX25L6445E features
a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus"). The only thing that i don't have is a way to read its contents. I have 3 Arduino nano (2 in working condition for the moment), but I don't have any code to do what I want. The chip is a MX25L6445E. Here is the datasheet:
,%203V,%2064Mb,%20v1.8.pdf
Probably, if I can get the dump of the flash chip, I will come back, with another flash chip that I want to read its contents.
The MX25L6445E has 67,108,864 bits of flash storage. The arduino nano has only 32kb. I don't know if the whole firmware can fit in 32k of flash of the arduino nano, because in the MX25L6445E datasheet, it talks about bits, and not bytes, so, I don't really know the difference. What I'm trying to avoid is to buy a proper programmer, just to use it one time. The first think that I did was contact with the router manufacturer asking them for the firmware, and they said that they won't give me the firmware because they can confirm that I'm a direct customer (because the router is from an ISP, so they are correct). If you, in your work, have casually made a firmware dump of a ZTE ZHXN H108N R1A, I would really appreciate if you can give me the download link. If not, I'm still thinking about dumping the firmware. One thing that passed through my mind, is to make the arduino, read all bits of the flash chip, and while reading, sending them via the serial port, and with an external program, on my PC, gathering all those bits, and putting them together to form a proper filesystem or IMG.
But, what I want is to extract the firmware to my PC. Copying the whole flash chip to another flash chip would be helpful, but, I don't have extra flash chips, and if I have to buy one of them, I'll use it only one time. What I'm looking for, is an easy way to do this, trying to avoid buying anything that I will use only one time, and using what I have (just the arduinos). If it's possible to dump the flash chip WITHOUT any other extra parts or chips, I will really appreciate if you can tell me. And, btw, isn't there any arduino code that "traducts" the micro SD card interface to a spi interface? If that its possible, I can probably use what you told me in the #3 comment
I don't have a dump of the router firmware, sorry. I think the suggestion of copying to another flash memory is a good one. I do wonder why you are so keen to keep an old router for which you can't get up to date firmware though. We use DrayTek routers, good quality at reasonable prices with firmware updates from their website.
I'm trying to use this router as a "repeater" with a wired bridge. The thing is that I can, and I'm actually using the router, but in its current state, it's very unstable. I think it could be because of the old firmware. I tried looking for OpenWRT but the variant that I've got isn't compatible. I like the idea of "cloning" the flash chip, but if I have to buy a flash chip, to use it once, I don't really know if I want to do that.
What I've said in one of my comments, is if there is any possibility to make my own sdcard 2 spi interface, and directly save the dump onto a microsd, and have it on my PC, using the same flash chip clone concept
Guys, I've opened the ZTE router that I want to update it's firmware, and, first, I've found that it has a MX25L12845EMI, it's bigger than the one we where talking until now. Second, the router has a 4 pin header. I don't know for what is ment. I've heard that in some routers, is met for firmware updates, or recovering the router. I don't know if we can use it for something.
And, @hzrnbgy, can I connect the SD card directly to the arduino? Do you know any code or library that can read and write directly to sdcards?
My ISP (vodafone) has given me the router on the title with their custom software disabling bridge mode. Does anyone know can I unlock this? Is there any way to flash the stock firmware? (I didnt find any stock images on the internet).
If this is rented ISP equipment chances are it's not in their ToS to allow you to flash different firmware on their unit. It could very well viod your contract and even get you in legal trouble as it could be considered tampering.
ZTE idoom ADSL ZXHN H108N dump file is shared below for repairing the firmware problem. ZTE idoom ADSL ZXHN H108N has the main board ZTE idoom ADSL ZXHN H108N installed in it so the SPI Flash file backup saved from working board ZTE idoom ADSL ZXHN H108N. Mostly in s universal board is installed which has the integration of backlight driver board, ATV Tuner Module and Power Circuit board. ZTE idoom ADSL ZXHN H108N dump file is shared below for the ZTE idoom ADSL ZXHN H108N repairing. If you are trying to load this dump file in another brand with same board then picture may be distorted or inverted. so, in this case enter to factory settings or service menu by pressing Service Menu Code on remote control and change LVDS Mapping setting to clear the picture. In some boards mirror/inverted image option is not available in factory setting so in this case change the flash dump file as per panel specifications. Before changing any setting value in the service menu, make sure you know about it well otherwise it is highly recommended that do not change any setting without proper guidance otherwise you get into the problem.
