Currently, only intraband CA is allowed on B40. Those are really nice combos but unfortunately, B1 and B3 are not configured for CA by “dtac” (not even B3+B1 is allowed). Upload CA, 4x4MIMO can finally work at the same time for 3CA B8-B3-B1 and I can’t wait to shatter local records with this device ? you’ve helped me make my final decision and now I have the Xperia 1 is right in my hands ? I have to say, the LTE speeds I’m getting is noticeably better than my previous phone. Even low bands like B8 gets 4x4MIMO which is even better. Thank you for adding my country to your table! It appears that the Xperia 1 already supports all the important CA combos here by default it’s nice to know that there is no need add or modify anything to get the best possible speeds that the network allows across all 3 major ISPs here. On screenshot i have removed all Upload CA enabled combos to make sure have best DL experience.
There you can remove and add more combos.
Modify CA-supportīelow you should find your serving CA combo list. Add +1 to number to know what is real band number. Here is example Finland and i have added 37 (B38) and 39 (B40). on there is defined bands what is supported per MNC. I recommended disable Xperia System Service on Xperia 1 phone so then it doesn’t load default configs when you swap SIM-cards with Disable Applications -app. Reboot your phone and then your phone load latest configuration. After modify file, please make sure XML syntax is correct and upload file back to phone. Now you can modify band limitations and CA combos to XML file. This is for second SIM-card.īefore edit any files, make backup all files what you will modify. If you have Dual SIM version, you should see also carrier_policy_Subscription01.xml file. Then go to policyman directory and on directory copy carrier_policy.xml to your desktop. Open Start Clients -menu -> QPST EFS Explorer.
You can download and install Drivers also manually.
Check on Device Manager you have Qualcomm Diagnostic Driver installed.
It should install automatically from Windows Update to your device. If you don’t see your device on QPST-application, please verify you have Qualcomm Diagnostics Driver installed. You should see now your phone on port list automatic. If you phone prompt “Allow Access?” dialog, please Deny because this change setprop value back to default. Then connect again to adb and run this command J9110:/ $ su Your phone will disconnect and reconnect. Open command line and run adb shell -command. Make sure your USB-default action is “No data transfer”. Then connect your phone with USB-cable to desktop.
Please enable under Developer Tools USB-Debugging on your Android phone.
Sony smartphones have software limitation and we will unlock this. But if you follow the steps exactly as i described it there is no way the software wont be able to communicate with the device, which was my frustration for almost an hour and a half last night trying to replace the PRL on my phone.On this instruction we will modify Sony Xperia 1 band combo profiles with Qualcomm software. I discovered this trick with an hour of frustration and agony. I launched CDMA Workshop and got my MSL code like the guide said, then launched QPST to upload the PRL I chose onto the phone according to the guide.ĭone. Window now recognizes the phone as a GOOGLE mass storage device, thats ok.Ħ. I rebooted the phone into Recovery then went into "-mounts and storage" then "-mount USB storage"ĥ. I went into device manager and chose my COM port like the guide said.Ĥ. Windows will now install all the drivers. Connected the phone to the computer using the usb cable, then turned the phone off "it rebooted instead, thats normal"ģ. In recovery I have also tried "mount usb storage" and "mount system" under mounts and storage and still no luck.Ĭan you tell me step by step exactly what you did?I used this guide and the drivers linked in it: Change PRL on Virgin Mobile LG Optimus V () - xda-developersĢ. What exactly did you mount in recovery? While my phone is in recovery and plugged in it is recognized in hardware manager but never as an active phone in QPST Configuration.
