I'm wondering if this affects people who are rooted and running 2.2? I know I haven't had any issues whatsoever.
I think we need to tighten up the definition of "factory reset" in order to shed any light on this. (And put me down in the "skeptical" column anyway - I'm not convinced it is anything more than an unfounded rumor.)
It has been customary to refer to the process of ROM replacement by rooters as a "factory reset" - but wiping and re-writing the /system, /data, and /cache partitions - even the bootloader area - is not the same thing that happens when you take a stock HTC Eris and perform a factory reset.
Sure, you have to start over reconfiguring your phone - but did you ever notice that you did not need to
activate your phone when you did this?
As of 2.1 for the Eris, the "factory reset" procedure was performed by the (stock) recovery boot - not the main OS. There are indications that this involves changes to the NVRAM area on the phone, and possibly the "misc" partition as well.
There are two reasons why I mention this:
1)
NONE - that's right,
NONE of the current root methods touch either of these two non-volatile NAND memory areas.
2) It is the job of the /sbin/recovery program within the recovery boot to do the work requested by the main OS - and it turns out that the version of /sbin/recovery in the Amon_RA recovery boot is not 100% compatible/identical with the stock HTC /sbin/recovery program. In practice, it is actually impossible to do a full "HTC Factory Reset" as it is defined by HTC with their 2.1 Eris ROMs when you are using the Amon_RA custom recovery.
Anybody that has tried a "factory reset" with an Amon_RA recovery partition can testify to the fact that they do not need to re-register their phone (*228), whereas if they did the "factory reset" on a stock Eris, they would have to re-register. Same thing goes for ROM installs - it is actually unusual that you would need to re-register, unless you had performed the FR with a "factory" 2.1 Eris (either the first 2.1 OTA or the second).
My own opinion is (first) that there is no
new risk in the rooting process even if there was a legitimate problem - because the rooting "factory reset" is not the same as that performed by a stock phone, and (second) that the claim made is unfounded and almost too hard to believe.
Let me see - there is a phenomenon that "no one understands", and is across a variety of handsets (from different manufacturers), every one of them with a different proprietary bootloader, and it is mysteriously and simultaneously date dependent on all different hardware.
Please.
