My PC is a MS Windows 10 laptop – If necessary, I could resurrect an old laptop and install Linux on it, if that is a simpler approach.
I have had a look at what is available and will probably load the ROM from:
What I think I need to do (and have tried to start) is:
1. Root the phone.
2. Backup the current ROM.
3. Unlock the boot-loader.
4. Load the Slim6 ROM.
To do 1. I have tried two methods, the first recommended from the backup thread and a second found by searching.
i. Easy Rooting toolkit: https://forum.xda-developers.com/sho....php?t=2292598 but the download link for DooMLoRD_Easy-Rooting-Toolkit_v17_perf-event-exploit.zip. The Download site for this tool tells me (eventually) that the file has expired or has been deleted by the owner - so i can't get this tool. Any Ideas How to get this?
ii. Also tried: https://forum.xda-developers.com/sho....php?t=2529561 but for me, the cydia impactor tool does not see my phone or have any options. Yes, I have enabled - and allowed USB debug mode, before you ask. And yes the PC can see the phone so the connection is good.
To do 2. I am proposing to use the instructions from this thread: http://forum.xda-developers.com/show....php?t=2292598 Please confirm this is still valid.
iii. [Update] Also tried rooting by using this thread: https://forum.xda-developers.com/sho....php?t=2457174 but this requires Framaroot 1.5.3, When I try and download this, the download site says: "The file link that you requested is not valid. Please contact link publisher or try to make a search."
Update 2. Managed to get a download of Framaroot, installed, but does not work for Xperia M with Android 4.3. Any idea of a way forward?
To do 3. I am proposing to use: https://forum.xda-developers.com/sho....php?t=2484622 Please confirm this thread is still valid - and the best approach.
To do 4. https://forum.xda-developers.com/xpe...allow-t3418258 - Please let me know if there is a more appropriate ROM to install to free up some space.
