Root How do i unroot return to stock? samsung i5700

[unknown-singh]

Hi i purchased a samsung galaxy portal I5700 (T-Mobile UK) pre owned. which seems to be running a custom firmware and has been rooted.

i just want to know if i can and if yes how to return it to stock, so that i can update to the official firmware when released, currently the phone seems very sluggish and sometimes very unresponsive with the firmware it has.


when i go to about phone it states:

Firmware version 2.1-Update1
Baseband version: i570EXXJD1
Kernel Version 2.6.29root@SE-S608 #2
Build number@ ECLAIR.XXJE1

Thanks

You'll likely get more responses to your query in the Samsung forums. I'll move this thread to that area for you.

You thread was moved to the i7500 forum, so I moved it to the i5700 Portal forum.

Sorry for the inconvenience and good luck with your issue!

Would also like to know this.

Is it just a matter of flashing the original firmware back to the phone?

 

[7500]

one way is to use Odin to install a fresh firmware.

Ok managed to go back to stock firmware but i still get the samdroid boot screen - is there any way to get rid of this?

Thanks

Did you use Odin firmware flash method, and if so what firmware version did you use?

Check out my root guide on how to install the latest JH6 firmware. This should install standard boot screen.

Failing that you can try info from this thread.

Hi Beerkan - yes i used odin to flash the firmware but i kept my 3 network software as im told i need this for things to work correctly, I used the method in this thread (http://androidforums.com/samsung-galaxy-portal/124315-root-guide.html) but skipped the first bit.

Edit: that is your guide

That is my guide.

It's following the second bit that installed the Samdroid Boot logo.

Follow the guide again, only just use the first bit. If you do lose your 3 network settings, you can enter them manually.

Copy this info
Menu
Settings
Wireless & networks
Mobile Networks
Access Point Names
Press 3 or (whatever is listed)

Make a copy of ALL these settings.

If you lose them, here's what I found

carrier="3 UK"
apn="three.co.uk"
mmsc="http://mms.um.three.co.uk:10021/mmsc"
mmsproxy="mms.three.co.uk"
mmsport="8799"
mcc="234"
