Hi Teltonika Crew,
I have a RUTX50 located in a mountainous region with no wired WAN and a 4G LTE connection that, at times, can be quite unstable due to atmospherics.
It it possible that you can point me to the upgrade file for RG501QEUAAR12A11M4G_04.200.04.200 applicable to a RUTX50.
This will enable me to load onto a laptop and do the upgrade, when I hike up there later this year.
Many thanks,
Mike
Bumped up ā¦ any news on this guys?
Hi,
I think you need to reach out support through your reseller.
Anyway, this wonāt be easy procedure to just upload file. Some software tools are necessary to do this.
Probably best option would be to exchange device if possible. You could prepare and test it at home, and just switch them on site.
Hello,
Thanks for reaching out!
Is there any reason why do you want to upgrade the modem? Your modemās FW not quite old one! We will provide the necessary modemās update file from server when itās needed!
Sometimes modemās may get bricked while upgrading , thatās why my recommendation is to wait until we release!
Kind Regards,
Caner
Simonas, Caner, you both misunderstood I guess.
Simonas: Manually uploading a firmware file through Web UI is super easy - once you have it.
Caner: I guess Teltonika is publishing updates so that people install them!
And as many people here in the Community already reported better speeds with version 11 (including myself), so please let people decide themselves if they consider this update as āneededā or not.
I donāt like those over and over questions āis there a reason you need that?ā or āwhat for?ā.
If software is publicly available itās there to be used.
Mike asked to have the file manually instead of clicking FOTA ā update from server for security reasons because his mobile connection is not the most stable one.
In order to avoid bricking the modem during upgrade, it is the safest way to upload the file manually from PC and not via unstable mobile connection.
So, once again the simple question:
Where can we manually download RUTX50ās modem firmware file
RG501QEUAAR12A11 M4G_04.200.04.200
in order to upgrade the router from PC and not via server?
What I donāt understand completely is why it would be more risky to upgrade the firmware by downloading it via the mobile connectionā¦
As far as I have understood the upgrade procedure for both the device and the modem firmware, it is a multi-step procedure that consists of:
I do not understand how an unstable mobile connection that might interrupt the data transfer or maybe even corrupt the data could in any way affect this procedure and make it more risky than when being performed from a local PC.
When there are considerations (like being put forward in some other topics) that the upgrade may fail when the modem is busy doing its thing while the firmware is being flashed, and it is recommended to turn off the mobile connection while doing the flash, would it not be the appropriate thing for the device firmware to do that automatically during a modem firmware upgrade (i.e. after the user has clicked āproceedā)?
Hi @Caner , thanks for reaching out.
What I require to be sent to me, is the firmware version RG501QEUAAR12A11M4G_04.200.04.200 for a RUTX50 - this is the latest version for the device and recently pushed out via FOTA.
I require this, to load manually on the RUTX50 via the UI.
The reason I require this is:
The current RUTX 50 modem details are:
MODEM MANUFACTURER: QUECTEL
MODEM MODEL: RG501Q-EU
MODEM SERIAL NUMBER: MPY23AB33001147
CURRENT MODEM FIRMWARE VERSION: RG501QEUAAR12A08M4G_04.200.04.200
Many thanks,
Mike
Hello, I think there is slight misunderstanding in this regard.
Modem firmware upgrade is only available via FOTA, if you choose āFileā and āModemā options Browse button used for device firmware upload is inactive:
So you would not be able to upload it via WebUI.
I understand that it might not be too intuitive, and will provide feedback about it for future updates.
Additionally updating from FOTA, except possibility of connectivity loss while downloading the firmware, which would result in failed download, but would not impair current device function, if it is downloaded successfully and files are verified it does not pose any additional risks during upgrade.
One more point, when downloading from FOTA your current modem firmware is taken into account and only needed updates/patches are downloaded, so even if you have several RUTX50 devices it does not mean that same file would be suitable for all of them depending on device current modem fw version.

Vidas.
Hi Vidas,
Thanks for your reply, the update is only for this one device so the one file would suffice.
I agree, the UI is very misleading.
Do you work for Teltonika and your answer is the Official Position on this matter, or do we wait for that statement and when they forecast that manual updates become an option?
If I ask Quectel, then they refer me to Teltonika to get a copy. I might also be imagining it, but Iām fairly sure Iāve seen threads on this or the Telematics forum, where Teltonika have privately shared instructions for a manual update and possibly a URL/password to download the modem firmware.
Hi Mike,
Modem upgrade from file only possible with full firmware file, and can only be executed from SSH, additionally RUTX50 has 90 MB user usable memory and ~100 MB user usable RAM space, full modem firmware requires more than that.
So you would need to set up either USB memory expansion or SSHFS partition from connected device.
Additionally performing upgrade, via SSH bypasses security procedures and checks, so there is actually added risk of installing corrupted upgrade file, or disconnecting either USB or LAN cable of connected device during update, which also takes quite a long time - bricking modem, and recovery procedure, if even possible, is even more complicated.
As result of these conditions, it is recommended only as a last resort with no other option available.
We were providing this option, usually only in cases of actual performance issues, as modem upgrade from FOTA via WebUI is quite recent addition, and was not available not so long ago.
IF you are still willing to perform upgrade manually, with full responsibility, I would ask for your patience, as due National Holidays we will be able to provide file and procedure, to you personally, only on Monday.
Regards,
Vidas.
Edit: sorry I missed your question, yes I do work for Teltonika. 
Hi @Vidas.K ,
Thanks and it seems a bit more complicated than I thought, and can still take quite a long time, which is unfortunate because Iāll have a battery powered laptop, where power will only last so long.
I think I will climb up there, grab the device and bring it down into the valley base station, do the update, and then climb back up there with the updated device.
One question ā¦
Even at our Valley Station, we can get 4G drop-outs and do not have a Wired WAN. Does updating via FOTA with a 4G connection, handle these drop-outs and ensures that all elements are installed OK?
Many thanks,
Mike
Hi Mike,
As I mentioned previously only āinconvenienceā in that regard, is that if connection dropout is significant/long enough - download will fail, and modem firmware upgrade will not happen. Then you would need to do the upgrade again.
However it is designed to NOT need internet connectivity during installation itself, only while it is being downloaded, as all required filles will be already in device memory and verified, to not be corrupted. So it is as safe with only mobile connection (possibility of being slightly annoying if connection is really Really bad, and you have to retry couple of times) as with any other option.
Just make sure that device is not powered off during update.
Hope this clarifies things.
Edit: to address term ālongā after download is done via FOTA it takes few minutes, full upgrade via file can take couple times longer, but still we are not talking about hours.
Regards,
Vidas
Thank you ā¦ Mike
If the aim is to de-risk the process as far as possible then can I suggest buying a second RUTX50, performing all the software updates and then swapping the devices out as part of your maintenance hike? I understand this involves the cost of a second unit but that sounds like a small amount of the total costs involved in physically attending the location.
Yep thatās a good option ā¦ itās one that Iāll put forward but the āwheels turn slowlyā in approvals and procurement
Hopefully I can get approval for a second device before I go up there. Thank you.
Hi,
While I do agree that swapping devices after making sure that everything is ok, is most ārisk freeā option.
If there is any remote access available FOTA upgrades, are as safe as manual ones (maybe even safer).
Unless it is mission critical solution and each minute of downtime is critical (and data is available in Sim card - IoT Sim cards can be notorious for data limitations).
Either way, if solution cannot handle being offline for more than few minutes you will have to be on location, manual via file, or remote via FOTA upgrade, difference is how close to the device you have to be IF something goes wrong.
Regards,
Vidas.
Hi Vidas,
As the device is not mission critical, Iāll grab it and take back to our Base to do a FOTA upgrade in comfort. Many thanks for your help and clarity.
Mike
