Here we have in one place links to (almost) every HTC Eris RUU Installer, OTA, and PB00IMG.ZIP downloads. (You can also find some archaic stuff at shipped-roms.com)
The Eris is getting long in the tooth - grab copies for your personal archive. Mostly this stuff is useful only if you have needs for older components (bootloaders, radios, etc) or need to assist someone with a Cupcake (1.5) phone.
Note that the "rom.zip" (== PB00IMG.ZIP) files from MR1 and MR2 are made available for folks desiring easy access to Cupcake (1.5) components - e.g. the 1.47.0000 S-ON bootloader.

OTA files may be renamed to "update.zip", placed on the SD card root folder, and then applied to phones with older stock software using the recovery boot. Note that all Eris OTAs were NOT FULL UPGRADES, BUT RATHER PATCH UPGRADES - afaik, they will only work correctly when applied to a very specific HTC software version already on the phone; including the "stock" recovery boot** for that software version. They will not work correctly with Amon_RA or Clockwork recovery.
Note there was a period of time when Google's servers were hosting two separate "July 2010 (2.37.605.4)" OTA upgrades: one of them upgraded existing 2.1 handsets @ v2.36.605.1, and the other upgraded existing Cupcake 1.5 handsets @ 1.17.605.1. Please read carefully.

** In the Cupcake (1.5) releases, you get past the stock recovery splash screen by pressing the Home (softkey) and End button simultaneously; in the Eclair (2.1) releases, get past the stock recovery boot splash screen by pressing Vol-Up and End simultaneously (a 2nd time if you powered up a 1.49.xxxx bootloader phone with the same sequence).
I performed MD5 checksums against all of these, and cross-checked prior references to insure everything is correct; if you find any reproducible discrepancies or MD5 mismatches when downloading please notify me via this thread.
