ReplyDeletefastboot flash volte.img cant load!! that the error showing
ReplyDeleteplzz help my device is connecting but serial num is not showing and when i typing the fastboot flash modem volte.img and pressing enter its says--> error: cannot load 'volte.img'
ReplyDeletehelp plzz
its because the drivers are not loaded correctly.. Reinstall Drivers... And use Windows 7 or win8.1 for the above procedure..
Deletethe fastboot loader ask to install only not shows any serial no and shuts down automatically
ReplyDeleteInstructions says.. if you see your device serial number printed in command windows then your device is ready to be flashed.
DeleteBut the main problem is volte.img file is not opening it says.. error: cannot load 'volte.img'
Now wht to do ?? :(
That is a common problem with CMD and ADB..
Deletewhile giving path for VoLTE image make sure that there must be no GAB in between the lines
like
"fastboot flash modem "c://users/haxx/desktop/new folder/VoLTE.img"
it should be like
"c://users/haxx/desktop/new_folder/VoLTE.img"
no gap..
Admin bhai kahan ho reply to karo yaar warna page band kardo apna
ReplyDeletehy Ezaj!
DeleteI am sorry i was unable to reply you, Because my Semesters are on going..
The problem you are facing is because you didn't have Asus Mobile Drivers.. I will update the blog with the drivers tomorrow.. Then you have to install them. Then you will be able to see your device in CMD..
Installing drivers will be a little tricky so try it, if you not able to do so them comment back here and i will connect you with team viewer and i will show you how to do so..
Thanks..

ReplyDeleteHi Vinaya. Still I m not getting any respons from you
ReplyDeleteThanks Vinay. Now i have update VOLTE in my phone. But unable to make video calls. Which i Earlier use to make audio and video both calls by jio calling app but after updating VOLTE that jio app also not working.
ReplyDeleteIts becoz Asus dialer doesn't support any video calling,
DeleteDo u c any option on Asus dialer for video call?
Jiojoin was design to rich and video calls, which is a 3rd party software..
Now hopefully u got the ans..
Will we got any update regarding video call in future. Other wise help me how to use jio calling app.
DeleteHaha buddy we don't know about any future updates, none of us r Asus developer :) and this is not an official Asus website :D, u can use ZenTalk app to connect with Asus. Post ur questions or ask to any MODs there.
DeleteIf ur device supports VOLTE then u can't use JIOJOIN app anymore.
So if ur device dose not support VOLTE then u can use JIOJOIN app, and its easy u know how to use it :)
can we do this by ubuntu os system??
ReplyDeleteYes ... Fastboot and ADB drivers Must be installed in ubuntu which is diffrent...
DeleteBro when i type fastboot devices command my device is not showing even though i go to fastboot mode

ReplyDeletewhere to type commands
ReplyDeleteIn CMD( Command of Desktop )
Deletefor me all worked correct but volte is not showing sir
ReplyDeleteThen u should hard reset ur phone from boot menu,
DeleteAnyway ASUS already launched VOLTE for ZE550KL devices u can try that way as well.
i am using ze550kl 2GB RAM.. software version is ww21.40.1220.1877 but not supported VoLTE..also no option for enhanced 4G LTE mode in settings option..
ReplyDeleteAsus always recommends hard rest from boot menu with partition cache clearing after every update,
DeleteAnd then if u still don't c the VOLTE option then try to update it again from ASUS's official website, if still that doesn't solve ur problem then here u gets an option as well.
does it work for Asus Selfie ZD551KL
ReplyDeleteAfter this procedure get volte.. but i can't able to hear dailer tone for my outgoing calls.
