[Q] Please help me flash my Lumia 710!

[io_gh0st]

Hello guys!

Let me tell you a story...

I bought an Lumia 710 a few days ago and now I want do debrand it and update it to Windows Phone 7.8. I've followed every single tutorial I could find on the internet, starting from debranding to unlocking bootloader and jailbreaking it. Didn't tried everyone in fear of messing the phone up.

I ended up on Nokia Care Suite with a few firmware files and a very huge desire to update my phone. The matter is that, as soon as I connect my phone to start the flashing process on NCS, it reboots (the phone), vibrates and keeps on this semi-power off state. I know that this was supposed to happen, but now NCS doesn't recognise my phone in *any* way. I can reboot the phone holding vol+, reboot holding nothing, start all over again... Just nothing.

All I want is to debrand my phone to a Nokia firmware (not a TIM one, I really hate those custom boot and apps) and update it to WP7.8, but I also want to work with Zune (sync and updates). Can someone PLEASE help me?

One more thing: when I was reading about all these stuff, I came up with the unlocking bootloader process. It said that I needed to have the Qualcomm boot loader, so I tried to identify it (holding vol+ and plugging USB) and it appeared on my device manager something like Qualcomm MSM blah blah blah. This means that my phone is with Qualcomm bootloaders, right?

Thanks in advance!

If device manager says you have a Qualcomm bootloader you are 90% of the way there

All you need to do now is download this downloader.exe
http://forum.xda-developers.com/showthread.php?t=1665821

Download NaviFirm Plus from here
http://www.symbian-toys.com/navifirm.aspx

In Navifirm Plus, navigate to here
http://localhostr.com/files/jXWZZOI/Capture.PNG

And hit the download button

When it is downloaded, goto the download location and copy this file to the desktop or a folder
http://localhostr.com/files/eT3POA2/Capture.PNG

Use 7zip to extract that file and you should have 'boot.img' file

Rename that to stock.nb (You'll need to enable file extensions to be shown so you can see the .img and .nb extensions - do that from folders view menu)

Now extract that downloader.exe you got from the first link I posted and copy stock.nb into the same folder

You should have downloader.exe and stock.nb in that folder

Ok, now unplug your phone from the PC

Power off the phone

Hold Volume+ button in and plug in the phone to USB > PC

When you feel the short vibrate, release the Volume+ button

IF THE PC ASKS TO FORMAT THE PHONE, PRESS CANCEL, DO NOT FORMAT OR YOUR PHONE IS DEAD

Wait for the driver to install (If it has not already)

Run downloader.exe as Admin

Press the button on the downloader.exe to start flashing the phone

Wait for it to complete then remove the phone battery for 10 seconds, and then put it back in and reboot into 7.8

Done

If you can't stop the phone rebooting after plugging in the USB cable, try it without the battery in

If you don't have the qualcomm bootloader, use this NSS to flash the bootloader then repeat the above

THANK YOU! Updated to Windows Phone 7.8 with this method

I don't want to sound inconvenient, but how do I jailbreak/root it now? This is the last thing that is missing

Thanks a LOT!

No problem

You can't actually jailbreak stock ROMs yet (Sucks I know), you have to flash an already unlocked ROM from one of the devs here

Same method as above, only swap the stock ROM for the custom one

(What I missed from above, and thankfully you were clever enough to know not to do it, is when the PC asks to format the phone, ALWAYS press CANCEL, DO NOT FORMAT or you kill the phone dead !)

And how can I modify an stock-rom to add these features? I was searching for it a few time ago, I've played with the OS Builder but I was a bit nervous on doing something wrong. I've also searched for some tutorials but haven't found anything yet. Can you point me where I should start?

Thanks!

I'd ask one of the devs here, I haven't tried to customise a ROM yet

Just reply to one of the 710 custom ROM threads or PM the dev

first, i would recommend you doing some reading: wp7 chef central

Already searched, nothing very well detailed...
