Tethering error

[kashyapkopparam]

Firmware: 6.1.1.B.1.54

I have 3G data enabled. I get the 3G/H symbol on notification bar.

If i try to tether wireless or USB , i get an error

Tethering Error

Error occured during tethering

I have reset the phone with full wipe.

I have repaired the phone using PC Companion.

But same problem persists. Please give me a solution to this.

so it is/was a network restriction

[kashyapkopparam]

It was because of an APN which is present by default in the USA firmware.

I wasn't able to delete or deactivate it.

[Uliwooly]

not at all, if your phone was network branded that's the issue not that the USA firmware has preloaded apn settings

[kashyapkopparam]

But my Xperia P has no branding. I got it from a dealer who buys phones from USA and sells it here in India. You can refer to this thread

perhaps he bought the phones network branded, the only thing that matters now is that your tethering works

[kashyapkopparam]

Yup. The phones works perfectly now.

Flashing the new .75 generic firmware using flashtool does not void my warranty, right?

P.S. I haven't unlocked bootloader or rooted.

Hey,

I have the same problem. I couldnt find the flashtool for xperia p. In sony website it is only specified for the following

Supported phones and flash key mappings

• Xperia™ T – volume down
• Xperia™ S – volume down
• Xperia™ arc – back
• Xperia™ arc S – back

Can u please guide me how to do this.

Thanks in advance.

This issue is with any of the unlocked phones sold in the US.  Xperia S, Sola, P etc.  I have confirmed it with Sony devs and they will be removing the hard coded APN in a firmware update.  If you flash a generic non-US firmware you don't have the tethering issue as stated.  Has nothing to do with network branded or not as the XS, XP, etc are not sold network branded in the US.

Temporary Fix to this Issue:

I came across this post in

http://forum.xda-developers.com/showthread.php?t=1932538&page=2

I kinda fixed it. I went into the tmobile apn settings and changed them to match my att settings. Tethering works now, only one problem. Now when I go into the section where it shows my different apn's it says "Unfortunately, Settings has stopped." It doesn't really matter though since everything is working fine. I shouldn't have the need to go back in there. I figure if there's an update it will fix that.

I tried this and it works.
