  6. Hi Chethan,

    I have installed Windows 10 Tech Prev on my Lumia 720 and its terrible.In simple terms windows 10 on Lumia 720 is disaster.I know that lumia 720 has only 512 RAM and is not sufficient for Win 10.

    So i reset my phone through settings in order to get winows 8.1 but my bad luck the phone got reset to again Windows 10 (software version 3058.50000.1425.0002) and OS version 10136.12634.

    I followed your steps to get Windows 8.1 and installed Windows Phone Recovery Tool but it is showing the latest software version 3058.50000.1425.0002 is available to install on my device and not the windows 8.1 or 8 whatever.

    I tried with lumia recovery tool also and the result is same.

    Please help me to get back to windows 8.1.

    Thanks in advance.

  7. Hi Ravindra, Thanks for dropping by. Are you sure the 8.1 is not listed in rollback options while using the recovery tool? Please double check.. I will check and let you know if there are any other solutions. Ideally using recovery software, and selecting the 8.1 version should bring you back to the old version. Even I have a Lumia 620, which runs on 512 Mb RAM as yours…

  8. Sir, I also have a Lumia 720 and I am also facing exactly the same problem.
    Recovery tool is not showing windows 8.1 or windows 8.
    It only shows ‘latest software version 3058.50000.1425.0002’.
    please help sir, I can’t even use whatsapp properly.

  16. Hi Chetan
    mine is Lumia 630 and build 10049. My lumia kept updating for some latest build, but halted many times on 0%, 4 %, 32 % or 27 % randomly. It was never successful update. It was also using lot of mobile data. Finally I did hard reset. After hard reset some installation process starts but halts after 10 minutes, a sad smiley comes on screen and lumia is switched off. What do I do ?
    I installed windows recovery tool, lumia recovery tool, but of no use. Whenever I connect my mobile to PC, two wheels starts rotating for about 10 minutes and ends with sad smiley.

    Than in advance

  24. How do I backup my Lumia 920 phone when I can’t get a Start Screen after logging on? All it ever says is “loading”, but then nothing. I need to revert back to Windows Phone 8.1, because Win Phone 10 Preview has rendered my phone useless.

  25. Well Guys… If you are facing same problem.
    Don’t worry just uninstalled your recovery tool and reinstall it as its downloaded stuff. Run registry cleaner and clean mgr. Restart your computer. then use your recovery tool and follow the instructions.
    Hope it would work for you… Same thing for Mac users as well.

  37. Nokia Lumia 930, I’ve been in the Insider programme and have Win10 (Fast Lane) installed. By accident I quit the Insider program using the Win10 Mobile insider tools (choose “quit” in the options) and want to re-join. Unfortunately this doesn’t work. When I try to re-connect to the fast lane I don’t see this option. Instead, I am being told that either my Phone is not compatible or I am not joining the insider programme. The latter is wrong (I verified on the MS webpage, I am still insider), but how do I get the tool to recognise my Smartphone/OS is compatible? I tried un-/re-installing the insider tool, reboot etc. I don’t want to do a cold-start not using the recovery tool to reset becasue I don’t want to loose what I’ve installed/configured.
    Any help???
