Xperia XZ1 701so doesn't recognize SIM nor does Wifi work stuck on startup

[waheedxda]

Hello everyone.

I have just got this phone brought to me by my little brother. It seems that phone is made for Japanese network (Softbank)

according to him, he downloaded few apps and was using it for few week until recently there was a problem and the phone had some issues. So he took it to repairer and the phone was flashed back to the company default

But now the issue is that the phone doesn't recognize any SIM and also WIFI searching forever without finding any network. I am not able to pass through this initial phone setup configuration to find out what exactly is wrong with the phone

Although phone restart with inserting SIM but soon as it boots to setup it acts like no SIM is inserted and prompt to connect to either network.

I have used Xperia companion with no luck cause the file size taking very long and my internet connection is not stable and failed on many attempts

Downloaded the exact Japanese firmware from Xperifirm and flashed using newflasher but still could not pass the setup due to no connection

I am not able to even skip that network and initial setup like all other android phone because the phone has to be connected to network and there is not step to skip

What could have gone wrong with the phone. Is this a software issue because the phone bricked by that guy accidently did something to software stuff or is it hardware issue? any urgent assistance would be highly appreciated.

I haven't touched the bootloader yet and as far I know it cant be unlocked?

Please help me resolving this issue

usually it happens when flashing the wrong baseband or modem firmware from another japanese firmware e.g. au kddi/docomo firmware,clean flash via newflasher should fix the problem,make sure to download the right firmware for your model (701SO),not au kddi or docomo...
if problem still exist after flash it,try to flash the global firmware (try CE1 firmware),it will convert your device to global variant(but nfc will not work and deep sleep not working)
good luck :good:

Hi and thanks @filandry

I have downloaded the exact copy of firmware as per my model (701so) and I even downloaded the UK customised version today and flashed it. The phone boots to setup but same issue no SIM detection and no wifi activity. I can't even see SIM or WIFI icons on the status bar

I am now thinking of whether if it's possible to somehow find this setup file and delete it in the firmware folder and then flash the firmware to see if it works when it gets to phone.
It will also help me checking the IMEI and other stuff but just wondering if its possible?

I know there maybe still few options to get the phone somehow into desktop but I am kinda newbie into sony phones and i wouldn't mind doing it

Edit; Just forgot the CE1 firmware part. How different is it from UK customised version? You really sure this will make a difference? Cause downloading a big file is a very daunting task for me as I am living in a place where we barely get 512 KB (shared 1:3) download time take a whole day for me.

you can try this via adb (i'm not sure if you can connect via adb since usb debugging not turning on)

or...try to boot up in safe mode
you can google it how to enter safe mode

Thanks for replying.

Adb can't be done since it needs usb debugging turned on and for that I need to get to the phone settings.
Safe mode already tried in the past and done it again for this new firmware but same issue

I wish i could flash custom rom so that its start-up settings might be different and no need to be connected
I really need help here if I still have an option
