Thank you jackie_w. I followed your instructions to install PRS+ on my Sony 650 and everything worked flawlessly. I am taking the liberty of adding instructions on how to download and install PRS+2.0.10alpha prior to installing 2.0.12beta Installer zip.

For anyone else who, like me, was getting very confused about the PRS+ upgrade vs. the Sony upgrade, here are step-by-step instructions for a PRS650 upgrade :

- from: PRS+2.0.10alpha, with Sony v1-0-00-08100
- to: PRS+2.0.12beta, still with Sony v1-0-00-08100

without worrying about what to do about the Sony v1-0-00-14080 upgrade which seems to have caused problems for some people.

The following instructions worked for me, but I don't claim them as the 'One True Way'. I'm happy to be enlightened otherwise
I would think the PRS350 would work the same.

Step-by-step instructions

Spoiler:

1. Download PRS+2.0.10alpha from the 'downloads' section of
   http://page2rss.com/c/0438c9e7d647f7...-not-supported
   
2. Connect your 650 to your computer (make sure your battery has a charge of over 75%).
   
3. Launch PRSP_650_2.0.10alpha_setup.exe and confirm that you want the program installed on your Sony. Super easy, only takes a minute or two to install the program. Your 650 is now updated with PRS+ 2.0.10alpha.
   
4. Download the appropriate 2.0.12beta Installer zip (not the setup.exe) to your PC.
   
5. Unzip and copy the whole PRSPInstaller directory to the root directory of device internal memory.
   
6. Precautionary step - don't know if this is necessary but I did it anyway.
   If you have manually installed the customised LRF/RTF/TXT font option, disable it temporarily:
   - Rename directory /test-startup to something else
   - Rename file /database/system/PRSPlus/prsp.sh to something else.
7. Disconnect from PC. Then do a full device shutdown, then restart it. The upgrade to 2.0.12beta will be installed automatically. You can check by looking in Settings - About to check version numbers:
   - PRS+ should show as 2.0.12beta (top of page 1)
   - Sony device info should still show as 1.0.00.08100 (bottom page 1)
8. Reconnect to PC and, if they still exist, manually delete the following from root of device internal memory:
   - directory /PRSPInstaller
   - file /runonce.sh
9. If you performed the precautionary step 6, re-enable the option now by reversing the renaming. Then do another full device shutdown and restart.
