i hv exact same problem as u as i installed AMonRA also but nvr rooted, i call HTC, HTC send me a old RUU for me to revert back ori ROM i guess, but half way through got problem and now USB cant detect whenever i run the RUU file..so no choice hv to bring back to HTC service centre 2moro...sian...

Factory reset will just wipe your data off the phone. It doesnt touch the ROM nor the recovery image.

You can go back to original recovery image if you had created a backup of the original recovery image. If you used the FlashRec application to flash AmonRa, you should have created a backup recovery image (e.g. recovery-backup.img) so you can flash back the original image.

If bring to HTC service center...will they do for me if i have already have amonRa in it?

why you want official 2.1? those Custom Rom that based on official 2.1 is much better!

Can give example? I find custom Rom always like in testing stage... Might be good overall but will have problem for certain function? Cause I am not a regular rom flasher... I just wanna do it right once.. n leave it as it is n use it...So I need a stable official Rom..The last time i flash mine is because i need the Market thats all then i have been using until now.

Got any advice? please suggest a custom Rom base on official 2.1 that is stable?

It's very easy to flash a custom ROM if you have the AmonRa recovery image installed.

A. Get ROM
1) Dowload your ROM. My recommendations:

2) Copy it to your SDCard's top folder (i.e. /sdcard/)

B. Launch AmonRA Recovery Image
1) Power off your phone.
2) Turn it on by holding both the Home and Power buttons and keep holding until you see the AmonRa recovery application:


C. Backup Your Current ROM (Optional but HIGHLY Recommended)
1) Select Backup/Restore -> Nand backup.
2) Press Home button to confirm.

D. Wipe Existing Data (Optional but HIGHLY Recommend)
1) Select Wipe -> Wipe data/factory reset. Home button confirms.
2) Select Wipe -> Wipe Dalvik-cache. Home button confirms.

E. Flash Your New ROM
1) Select Flash zip from sdcard
2) Select your ROM to flash. Press Home to confirm.

If something goes wrong, you can always revert to your ROM as long as you created a backup (Part C).
1) Select Backup/Restore -> Nand restore
2) Choose your Device and then the backup you made.
3) Press Home to confirm restoration of your ROM.

wats the use of dalvik cache actually?
whenever i want to wipe dalvik cache, it gives me error..

if i wasn't wrong, dalvik cache is the linking of all your apps and the OS

The Dalvik cache contains the optimized version of your applications (.apk) files. They're created only once for each application installation.

Sometimes if you don't wipe the cache after installing a new ROM, some applications may not work properly and crash. I don't really know the reason why, but I think it may be because of inconsistency in the Dalvik cache.

Just update my Hero at HTC Plaza Berjaya with the following software version, seem like different from HTC website stated one, any ideal why different? mine latest build?

Firmware : 2.1-update1
Build no : 3.34.707.1
Software no : 3.34.707.1
Browser version : webKit 3.1

You have the 2.1 update. Good.
