Very tempted but can't bring myself to do this manual update. Not sure why, I have been a computer/software/tech professional since before some posters here were born but just can't do it. It's probably due to the fear of missing something important from Verizon if I don't play by the rules. My phone is an indispensable tool for me. I have no problem being patient, my temptation comes from the idea of having a clean load. And after reading this whole thread and some posts in the android forum I still do not completely understand the genesis and composition of this file. We are told that it is the same file that came in the OTA with some different scripts (created by whom?) to apply the upgrade. We are told that the OTA patches the OS while this file is a complete install. So how are they the same file? Does the OTA contain the complete install but the scripts that come with it pick and choose which files to install while the scripts on the OP file install all the files?
Although I am very experienced with software I am pretty ignorant of Linux and Android so I am just not getting this. I understand the windows analogy but on the other hand I am told that the android OS does not deteriorate over time or leaves garbage behind like windows does, so how then is this "clean install" better than the OTA?
Sorry for all the questions, I have an idle mind right now
The larger update, linked to in the OP, was built by Motorola (just like the smaller one) to allow Verizon techs to recover phones corrupted by the earlier install. This is theory, but seems to fit the facts. The signature is the most important part, but more on this later.
The smaller file is the one being pushed out OTA. It works, but has had a higher reported percentage of borked installs, many of which have been corrected by installing the larger file over the smaller one. A lot of people, all more skilled and possibly smarter than me, have looked into the guts of the larger file and have declared it clean of malicious intent; indeed, the signature alone would indicate it's clean. Nobody has yet discovered a way to sign an update.zip so it would work with the stock recovery. Hopefully nobody ever will or a lot of people are suddenly in danger of having their phones hijacked.
It's not the "same" file in the same way brothers or sisters are not the "same" person. However, they do the same thing as far as the end user and Verizon are concerned. They install FRG01B. One does it in a method that leaves less room for trouble while the other requires less bandwidth to push out to the end users, most of whom are still unaware there's an update being pushed, let alone what it is and why it's important.
Patience is important. However, keep in mind that there's no guarantee that the OTA when it hits your phone won't mess it up. Verizon will replace it at that point, yes, but if you push the manual install onto your phone and it messes up, they'll do the same thing because it's all their software. The reason for the smaller update being the one pushed out OTA is to minimize the impact to Verizon's 3G network as this is a MAJOR rollout.
Whenever you patch something big like this, as I'm sure you're aware, you modify code inside some files and replace others. The problem comes in when you're trying to modify so many files at the same time that bit errors creep in. Get enough of those and the error correction capabilities are overwhelmed and the system can't keep up. This results in lag in varying severity, and in the worst cases force-closure issues and even boot loops. The "cleaner" install overwrites, installing clean code everywhere instead of leaving parts behind that might have been corrupted at an earlier date for whatever reason. It's "cleaner" and "fresher" and results in fewer "wrinkles" for the end user to do it this way. It just cost Verizon more, and their number crunchers probably figured that replacing X number of phones was cheaper than loss in revenue that would have resulted in rolling out the larger file. This last part is pure conjecture but also fits the facts.
Cleaner, fresher, and fewer wrinkles. This is the first time I've ever heard of FroYo being used as a fabric softener.
