Download Flash Modem
Amy Sumler
While out yesterday a storm hit with lightening and on my return my internet was down. On checking my CM500 Modem all lights were flashing rapidly off and on. I unplugged my modem for 30 seconds and plugged back in, but no change. I tried another outlet, no change. BTW there are other things plugged into the surge protector outlet where the modem was plugged into and all of those things are operating. I then called Comcast who could not reach my Modem. I then tried to reset the modem to no avail. Comcast is sending a technician over later this week. My question, is there any reason that all lights would flash or that the power light would not turn steady green unless there was an issue with the modem itself? Don't want to pay Comcast $70 to tell me I have a bad modem.
Unhook your coax cable from the modem. with it powered on, hold the reset button until the lights change. Might be up to 30 seconds. If you can't get the lights to change and they just stay flashing, probably a bad modem. the others devices might be fine but there might have been a surge in the coax line that caused it and why it only effected that device.
Comcast came by and had to redo some of their lines and also dropped me a new cable to my modem, so they will not charge me for a service call. As suspected the modem was fried and have ordered a new one on Amazon as suggested. I think safe to say when everything is flashing including the power light you have a bad modem. Thanks for the help.
I have a Netgear C7000v2 modem/router that I want to flash with custom router firmware. My understanding is that you wouldn't flash custom firmware to a modem, based on this SO post. But if I wanted to flash custom router firmware to this device would it be possible? I haven't found the C7000v2 listed in the supported devices of either open-wrt or dd-wrt, but I'm hoping that it's still intended to be possible by installing the firmware of a similar modem-less model.
Edit: based on this C7000v2 datasheet and this R7000 datasheet, the devices have different SOCs/CPUs but have the same wireless chip. I'm guessing this means that I can't flash my C7000v2 with R7000 firmware?
First thing I found confusing is: On the Getting Started Tab of the product site, right above the Video there is a sentence: "To ensure optimal functionality, please update the nRF52840 SoC FW, the nRF9160 SiP modem FW and then the nRF9160 SiP app FW in that order." But when I follow along the video and/or read the docu (here and here) it seems there is no need to update the firmware of this 3 modules on there own, it seems now it is all together, maybe you should remove this sentence or maybe I had gotten something wrong?
But this is not the point of my post, I tried to update the modem firmware of the thingy:91 and ran in a problem others mention here in devzone before, the Update fails with the following message:
yes the LED lights not up when I am pressing SW3 and then powering on, she is ligthing up when the Error in the Programmer It lights up only at the moment when during the modem update process the error message appears in the programmer. (If I dont press the SW3 switch and powering on the Thingy:91 the LED lights up directly after the powering on.
Sorry for getting the Sentence wrong, I totally understand that is a big piece of work, and adding a quick fix seems totally right, now I understand what you mean with this sentence, but where I can get the FW of the nRF52840 SoC and how could I programm it? when I am searching at the nordic homepage I could only find the nRF52840 DK, should I use the Interface MCU Firmware from there? I am also looked into the infocenter under nRF52840 but don't get any Information about the FW download of the nRF52840 SoC.
So now I have connected the Thingy:91 via USB Cabel to the Computer, Pressing the SW4 Switch and Powering the Device on, to set nRF52840 in Boot Mode, cause I wanted to flash the thingy91_nrf52_connectivity_bridge_2020-10-30_5522ca2b.hex file. The LED was blinking, so I tried it again, cause I remembered you note that the LED should not Blink when in MCU Boot Mode. So I turned the device off, holding SW4 and powered it on again, LED was blinking, so I re-read your Post, and I mentioned, that the LED should be off when 9160 is in MCU Bootmode, so I thought maybe LED is off only when the nrf9160 is in MCU Bootmode and not when nRF52840 is in MCU Bootmode. I connected with the Programmer to the Device and flashed the thingy91_nrf52_connectivity_bridge_2020-10-30_5522ca2b.hex file, MCU Boot was checked. It started to working properly, but when the status was around 88% the programmer Window was going to be complete white, and nothing happend anymore. After waiting for 5 Minutes, and nothing happend. I restarted the programmer and also the Thingy. But now the Programmer doesn't find the device, no matter if in MCU boot mode or not, and I also can't see it as USB Device at my computer. what should I do now, programming via a external debugger, J-Link or something like that? Or is there a opportunity to reset everything? what was the reason of the error? Was anything wrong in the procedure I was doing/ had described here? Here is a Picture of the Programmer after getting complete white:
During boot up, Power is solid for 35 secs; the DS will then blink for a minute; lastly, the US will blink for 15 secs before the modem goes into sync with the ISP. When the modem synchronizes, the US/DS and Online lights will remain solid. The Link light will blink indicating activity.
Here is also an older python script that can be used to update the modem: nrf-dfu-tool.zip. It might also give you a bit insight into the process of updating it, and what it is that makes it a bit different.
hi, i'll have to implement a 60d with lte connection(the only alternative is a crappy adsl 640Kb). given that the lte modem will be the only connection i've to choose wisely the modem. anyone that had already work with usb modem that can suggest some valid one?
First, do not complicate the setup by using a FortiExtender. I did, and I've paid with weeks of trail and error. FExt and FGT support different subsets of modems, there are settings in the config which pertain to both and some which only affect one of the two.
The main obstacle is that web sticks (modems) often/always offer 2 modes of operation: one as a modem and one as a flash disk device. The tricky part is that the FGT has to send the exact code sequence to switch the modes, and these codes are model dependent. Even if the model number is equal, there can be incompatible 'sub-versions' of it which you can only determine when peeking at the micro print on the stick itself. You do have the choice to enter a switch sequence yourself but that isn't documented well (neither from FTNT nor the modem's manufacturer) so that it often ended in trail-and-error with me. It tooks some time and several modems until I got it to work.
Having said that I recommend going with Huawei sticks. There are quite a few models supported in FortiOS so that you'll have a chance one of these is still on sale. Then, I dug up info on how to switch the stick permanently into 'modem' mode and did that on a PC. Only after that I connected it to the FGT/FExt and it worked.
You might want to try ModemManager and luci-proto-modemmanager, both of which are in the master branch. ModemManager is in 19.07 but the luci-proto (GUI component) is not. Both are unofficially supported in 18 (you need to compile it), so to get it you need to add the unofficial feeds.
After this, nothing is sent from the modem even after a long time.the +STKPCI SEND SHORT MESSAGE in my opinion sends the Short message. I also do not know what 0101038154F5000410E18B8FBAC72115E05B54866E5C667593 means, in the docs, this should be the SMS tpdu but I am not able to decode/parse it. I need to be able to send the STK SMS without browsing through the menu over and over again.
I have a modem/router (DSL-2750B) with a external hard drive plugged in the USB port. My idea is to download files directly to the external drive instead of my PC. The reason why I would like to do it is because I want do download a lot of files at night without having my PC turned on (OS: Ubuntu 14.04 and Windows 10).
Another option would be to get a Raspberry Pi or similar mini computer to do the downloading for you. You could either hook up the USB drive directly to the Raspberry Pi or have it access the drive as a network share when it's connected to your router. A small computer like this would save a lot of power over leaving a desktop on to do the same thing, and you wouldn't have to worry about flashing your router with different firmware.
Anyways, when I insert the sim/sims (TMOBILE US) it does not flash at all, just stays a constant bright white. I tried using HyperTerminal commands (dont know much) but for some reference for the helpers here it is.
I noticed recently that the "TEL1" light on my modem is flashing. I dont' know exactly when it started, but it did not flash in the past. I talked to customer service (via chat) and they gave me the standard response of "line in use or phone off the hook". But when I reminded them that I did not have phone service (and do not have a phone hooked up to the modem), then they said "Your modem is not apportioned for phone so that's why it is blinking". That would not explain why it just started blinking recently though.
The device is operating as modem and seen in Network Manager if only it's attached before OS loading. If after, it's detected as flash. The all mine attempts and games with usb_modeswitch are in vain and wasn't came to good.
It seems once I got a new PC with Windows 7 and installed the latest version of Access manager, the USB Modem will not connect and gives an error saying that the network profile is invalid or not found. Is there a fix, since the staff at tech support (they tried their best) said it was a compatibility issues with Windows 7? I did not have any problems with it under Windows XP but now that all PC's are running Windows 7 and soon 8, I would like to keep this modem vs. buys a new one.
