Blackberry z10 stl-100-1 i.d bypass

[toptech]

I am looking for a working solution to bypass the I.D on blackberry z10 stl 100-1.Please dont give me solutions for blackberry STL 100-2 STL-3 OR 4 because they are not the same.I have searched highand low without success for this particular model.I even did the downgrade but my only success was to get itno the menu using 10.3.1.997 but unfortunately it does not have all the apps .Just a few apps without the file explorer and some of the most important apps.If someone can point to to a higher version of the 10.3.1.997 ,i should be able to get the other apps and file explorer.

Thanks in adavance to anyone who can kindly help
