#19436397 5.3.6 ARM-Unable to use ReadyNAS remote

Ok right now I am back to 5.3.5 firmware on my ReadyNas
I am running (still) version 1.0.9.81 of the Add-On on my ReadyNas
I am running 1.6.5.16 Remote App on my Windows 7 (64-bit) DeskTop PC
I am running 1.6.5.16 Remote App on my Windows 7 (32-bit) NetBook
I am running 1.2 Android App on my Samsung Galaxy S2 SmartPhone

Current results: -

1. Everything appears normal on my ReadyNas under configuration/settings - ie; I do not have the former 5.3.6 icon/switches anymore
2. Using my DeskTop PC without using ReadyNas Remote, I can login to my server ok and can see all my shares and files no problem - my network is working fine
3. Invoking the Remote App on my DeskTop results in me logging in to the Remote Service without difficulty but when I try to connect to the ReadyNas, an explorer window pops up but it is completely empty - should have an icon saying ReadyNasDuo - the name I have given to my server. I am trying to connect using my Admin username and password - previous to all this messing about, I could do so successfully
4. Using my NetBook PC, I can login to the Remote Service no problem AND can connect to the ReadyNasDuo via WiFi with No problem :) - I have allocated a separate username for use with this device
5. Using my SmartPhone, I can login with my Admin credentials but when I tap my server on the screen it says "trying to connect" and eventually gives up.

I haven't as yet asked my other users what they experience but will do so later and will report back. I know I wouldn't normally connect to my server using the App, whilst on my DeskTop, my network is sound for this but I was able to do so before. If my other users can connect without difficulty, then the only problem which remains is with my SmartPhone.

Questions for now please: -

A. Can someone please point me to the previous version of the Android App, which I was formerly using - or tell me if there is a way of reverting back - it was working before I updated to v 1.2

B. Again I need help doing an OS reinstall on my ReadyNAS. I muaybe doing something wrong - please read up to a former post. When pressing the reset button and keeping it pressed - when you then press the Power button, how long do you keep this pressed for before pressing the Backup button to scroll through the options? As I have said, when I press the backup button all the lights turn off, save for the Power button light and continuing pressing and releasing this button does nothing. I have been successful with this before and used the instructions downloaded for my V2 Duo which I posted above.

Thanks again and look forward to some more help :)
