Huawei B535-232 - Failed Update, Lost Menu & Offline: How to Restore Firmware?

Question

Hello.
I updated the modem with the wrong firmware. The effect that the device is supposed to work, but there is no menu and it is offline.
Is it possible to upload the software in a different way than from the menu?

You probably need to disassemble the modem, connect via UART (if mabo has the right pins) and have a batch file for the programmer - I'm guessing, but this is how you save the equipment completely dead (if it shows any activity via UART).

I've searched a bit on the net, tried, etc.
The modem generally works. Connected to another router via WAN, it transmits internet, wifi broadcasts, etc.
The problem is that I can't login to it as if it had no configuration menu at all (WebUI??). After entering the address of the router 192.168.8.1, this address changes to the address https://hirouter.net. and that's it.
I tried to log in via Ai Life, the router is detected, but I can't enter the configuration menu.
The Update_WEBUI_10.0.1.1(W2SP3C55) application detects the router but has a problem with detecting the ports and aborts the update.

multicast_upgrade_tool - I can't set the router to Update_mode... and the program doesn't start, besides it shows me a message about the wrong file.

Anyone got any ideas?

I have the same problem. Where did you get this Update_WEBUI app from?

adriansi · Answer

firmware and so on I will unpack the files with the program from the package or download it from the net because my antivirus shouted something there. The update_webui app comes with firmware files named webui.

For now, I have a console after uartie, but the hell is not going to stop uboota

So this application is to be updated via USB. There is something missing on the board. On the example of B525 - puts the router into flashing mode, connects the usb cable to the board, launches the application. She's just looking for a virtual Com

So it looks like there is some problem with the SSL certificates and that's why the page is not displayed. People were hanging out with similar topics with huawei 5G modems.

In general, the API speaks, the router works (without the gui of course), even by some miracle it manages to connect with the AI life application from time to time - anyway, probably after this API. I don't know how I did it. Rather, it was AI life from the playa store in version 11 than a moment later updated to version 12. After configuring the APN in this app, 4G transmission is heard.

It seems that the solution will be to use the API to log in and force download the update (e.g. original WEBUI 4SP983 for me) from the file.

I'm too skinny for that

Well, it is still necessary to invent where they skitrali USB on the disc. It is possible to enter the boot usb mode modem after shorting the USB mode pin from the drawing to GND. You can see it in the UART console

And the router is on chips:
Hi6932 (BB), Hi6559 (PMU), Hi6362 (RFIC)

Balong Hi6932 or V7R22 also has B525 / B528, so in case there is a usb loader

pawol · Answer

I bit the tamat and found the USB. However, loaders from b525, 528 and e5785 do not match. I contacted the Russian developer of the usbloader and we'll see what comes up

pawol · Answer

I found out that by starting the modem with reset+WPS pressed (hold 10 seconds after starting) we enter the multicast upgrade mode. The PC network card should have IP 192.168.8.100/24.

Puki what flashes only felerne B535_11.0.1.2 (H200SP2C21) for the same. Other versions cling to the wrong C version. The FW file must have the .bin extension (the package contained .zip without .bin)

pawol · Answer

So the cause of the bug is the fact that there is usually no webui in the firmware packages. There has been a crossover between the compatibility of the modem firmware with webui. There are supposedly MIX packages containing modem and webui firmware in one.

https://qyyd5g.top/%E5%8D%8E%E4%B8%BAB535-232(%E7%8E%B0%E5%AD%98)%E5%9B%BA%E4%BB%B6%E6 %B1%87%E6%80%BB/

and it should be uploaded via multicast.

Puki what internets do not find such packages

pawol · Answer

Multicast tool with the ability to load webui and modem separately.
It's still a matter of finding the right pair of packs.

Personally, I'm looking for webui W2SP2C7201
or packages MIX-B535-232_UPDATE_10.0.1.1(H191SP61C983).BIN because I had the modem originally from Orange

pawol · Answer

The only source I know of for paid packs (about $5 each) %B1%87%E6%80%BB/

If anyone was looking for firmware for version 535-232, here I managed to find quite a large package posted by someone in the first post:

pawol · Answer

Well known but not very useful. The problem is that the b535 packages must be a modem - webui pair because they are signed. The Chinese table in the post above explains it. Soft cannot be loaded if it is not from steam. Unfortunately, there is not much webui on the net, even in the C7201 version. The rescue is a mix package, which are also unavailable and the Chinese does not speak.

You can't change the C version of the packages either because it's locked. Also without the proper original packages is linden

pawol · Answer

I am attaching the original usbloader for B535-232 for posterity. Usbloader is not patched and therefore there is a high risk of erasing sensitive data (such as IMEI) in the flash memory. And since we are dealing with signed softs in B535-232, it may turn out that we will get a brick.

pawol · Answer

With this multicast tool you can force a C version change but you need a key. The key looks like it is assigned to the PC so someone would have to warp it so that it does not ask for the key
