I just want to know considering the fact that my device is developer unlocked, after the installation of new update on the device, will my unlock remain intact or I will be forced to unlock the device again?
I do not see much or any bugs on the device and I see no point in updating the firmware as well, but just want to know what would happen if I did, as I have zero knowledge on the whole thing.
hi, if your device is unlocked, after update will remain intact. Zune make normally a backup before install a backup (but not shure if by each update). to be save do a backup:BACKUP now your unlocked MANGO phone - to RESTORE over ZUNE tnx xboxmod
Unzip WP7 Update Cab Sender.zip on your computer. Its a update/backuptool. it contain a dummy cab- it will backup your phone- but nothing update. Run the WP7 Update Cab Sender.bat
(without ZUNE run). If you get a error, please install the tool from folder "if needed install this tool
After run the WP7 Update Cab Sender.bat type B
for (fake) update and real backup
. If you have already a backup in C:\Users\UserName\AppData\Local\Microsoft\Windows Phone Update- please cut and paste it in a save place.
After all you will get a error message.
Is o.k. ignore the error message. Your BACKUP are succesful done. the error causes from the "fake update", the update cab is only a dummy and is neeaded to activate the Backup procces.
to see this path/files, you have to activate under windows explorer folder options "visible hidden files
" The Backup files you will find in C:\Users\UserName
\AppData\Local\Microsoft\Windows Phone Update, such as this folder name d4e21648 - xxxxxx - xxxxxx - xxxxxxx.
When you then connect your phone and start ZUNE, and search to updates, ZUNE tell you "your phone software is actuall and you get the RESTOREPOINT. Copy/Cut the Backup folder from ....\Windows Phone Update to a save place
INFO: If you RESTORE it over ZUNE plase be patient, the first 10 minutes you do not see an progress- but wait it will!
f the screen go off, turn on and lock off the screen AND wait!Restorations duration is ca. 40 min. please do nothing
with the phone in this time. be patient
. After Restorations connect again with ZUNE, then you get Samsung App Store alo back
I will not take any responsibility for any damages caused directly or indirectly from using the software-package or the instructions. Read the instructions thoroughly and proceed carefully!
