Huawei original firmware, this is not a customized firmware. Prison break season 2 cast. Disclaimer: Administration of routerunlock shall not be liable in case of unknowing change of the firmware of your modem / router / MiFi. Moreover, if you want any specific firmware of related to Huawei dongle / Pocket MiFi, then leave a comment, if it will be available then will be published. Huawei have released a OTA software update for the B315s-22, version 21.313.03.00.983. After you install this update LTEwatch will no longer retrieve signal information from the router. Do not update if you use LTEwatch and want this information available. Now I need help to see if I can downgrade my router. The first step is to find what the last working software version is (I did not have a chance to note it down). Can B315s-22 users of LTEwatch tell me the software version of there off the shelf (not provided by network operator) B315s-22. You can find it if you log into the router under the settings/system/device information. Once I know this hopefully I can download it and downgrade the router. Veccu's suggestion does not work, I am not sure where he heard that idea from either, I did a quick search and it seems that is more related to unlocking operator locked routers (which mine is not). Indeed it is a general firmware and it comes with preset Elisa settings, The situation is Huawei have told me my operator (Elisa) pushed it to my router because as a company Huawei do not push updates regionally or worldwideto routers (at least that is what they have told me so far). What I really need is the previous firmware version to hopefully fix my problem which is 21.311.03.00.983. Some one somewhere must have it. I called the Huawei support service line (09 23 13 89 98) that then gave me an email address to their support staff who are also dealing with it. The support staff on the phone and email responces suggested only the operators do OTA updates. I have told them what you have said previously and they have emailed me to say they are looking and will report back once they here something. I guess Huawei forgot to memo their customer facing staff they are doing OTA updates from what they have told you now. Hopefully they have tied your contact with them to my contact with them but if not I guess I can give them the link to this thread. If they still say something different. After a little effort I finally managed to get Huawei to give out the previous firmware (they seemed to be against for some time or could not find it). The link to the previous firmware (21.311.03.00.983) is; Now for the downgrading. I would suggest you first try to downgrade by simply selecting the firmware above through the webUI update page. I am quite sure this will not work given what I have heard but its worth a try first. I personally used a different method (explained below) given I found an even earlier firmware on the net (21.300.03.00.983) before Huawei released the firmware above a couple of days ago. Now for the force downgrade method incase above does not work. You will need three pieces of software; ‘E5186 Toolbox’, ‘B593s-22_Multicast_upgrade_tool’ and a telnet client (I used putty). I will not supply these softwares but google is your friend. The process involves using the E186 toolbox to put the router into a mode where it accepts a telnet connection. Then giving a couple of telnet commands to the router and finally using the multicast tools to update the firmware.!!! DO THIS AT YOUR OWN RISK!!! I basically followed this video from the start up until around the 6:15 mark. In my case the end of the multicast update part (where the router shows progress with the signal leds), my router did not reboot itsself like the video appears to show so. I simply let the multicast tool run about another 10 minutes (while the router indicator was green) until I finally rebooted manually after stopping the upgrade tool. Please let me know how you get on.
