Thanks Ron! Just to be sure - If I have those files on the card, the system should start the update process on it's own? Is there anything I could do wrong with the files themselves that would prevent the process from starting?
I tried with a new 8GB microSD formatted to FAT32 with cluster size of 4032 which is default. Still no action when I plug in the SD card. I'm wondering if I'm missing a file or have the wrong file. I see conversations related to both the CARDINFO.CIF file as well as the VERINFO.DAT file. Could I have a wrong one of those? Again, is all I'm supposed to do is plug in the SD card while radio is powered on and it'll go or is there something more? I have a PhD in engineering and I'm not used to things being simple. If possible, can someone point me to somewhere that lists the whole process assuming I know nothing (which is actually pretty accurate at this point)?

The root of the SD needs the Cardinfo.cif file (the CardInfo.txt from #140 renamed), FIRMWARE & UPDATE dirs. That's all. Don't change VERINFO.DAT. Its already been patched.
Other potential problems are the zip archive extraction. Did you use a Mac? That's been known to cause problems. What program did you use to extract the files? Some prgms don't extract all the files to the proper subdirectories.
BTW, I have a Z110bt, which has a regular SD slot. I've had problems using a microSD (with adapter). Does the x920 have an SD or microSD reader.

Oh, that explains it.

Don't know how it could be made much simpler. Try listening to a Trump speech beforehand. That should loose you a few brain cells." Trust me, It'll be so wonderful. You won't believe it!" 
Ron, Thanks a ton! I think I changed the VERINFO.dat file. I'll put it back. My x920BT does have the microSD slot.
I'll try the Trump thing... may work!
Also, I noticed back in one of the threads that someone formatted to a FAT32 with 16K clusters instead of 4K ones and they said it worked. I'm going to step out and try it with 4K clusters and see if it works.
If the VERINFO.dat file is wrong, is that enough to stop the process from starting?
No MAC, using x86. I used the zip extract tool built into Windows 7. Any worries of that working?
Okay, so I tried the 16k cluster size formatted sd card and still nuttin. As a last resort, I thought I would reset to factory settings and that actually solved the bluetooth issue that drove me to this whole project to start with. I think I won the battle but am still losing the war...
Not sure where to go at this point.
Okay, life is good! Finally figured it out. Darn Windows kept leaving the cardinfo file as a .txt after I had changed the name to .cif.
My bad. All is good and updated! Thanks for all the help!
