I already have a nandroid backup on my sd card and computer through CWM
1) I go to XDA download rooted and odexed 4.22.651.2 (prefer the simpler one).
2) Save that file to the root of my SD Card.
3) Power down then turn phone back (press volume down + power)
4) Go to recovery wipe data in factory reset, wipe cache, wipe dalvik.
5) Then install zip from sd card. Highlight supersonic 4.22, yest to install. (This is where I'm confused) GB should install then and there right?
6) Reboot system and then go through the entire process of starting up phone like if I had just bought it. Right?
I'm trying to find out the most information I can because I've been told that using unrevoked was not a good idea because I can't download different roms.
welcome to the forums!!!!!!!!!!!!!!!!!!
you are dead on with everything you posted. i would also mention that you should use
Calkulin's_FORMAT_ALL.zip. it just wipes does the wipe again. just flashed that prior to flashing your rom.
and yes it is definitely not a good idea to unroot. because you will not gain root again until a new exploit is found with the new hboot.
Hello everyone. Like many others I am new to rooting and have a few questions about this new update. The informaton here has been great and the patience with the new folks is commendable, thanks for that. My issue is that right when i think I know what I'm doing I run into contradictory info.
Let me explain what I'm working with here. If I understand all the terminology correctly I believe that I am starting with a rooted stock Sense rom. I believe that to mean that before I rooted I had a store bought, Sprint HTC EVO with the Sense UI out of the box. I then used unrevoked3 to gain root acces (s-off right?) and have not instaled any themes or custom roms. I have installed the following root only apps:
Titanium Backup (TB) - only used it so far to run a batch backup of all user apps + system files that now appear to live in a Titanium Backup folder on my sdcard (couple of hundred files in there it seems, thought it would be one large compressed file...)
SuperUser - because something in the root guide I followed told me I needed it and I have had things ask it for permissions.
CacheCleaner - because I read that it would help with a pesy low space error I was getting (it did)
Wireless Tether - self explanatory - seems to work well if anyone is interested.
That's it, the full extent of my rooting experience thus far...(rooted last weekend).
After reading the above post i thought I had this gingerbread OTA update thing figured out until, that is, I came across this thread:
http://androidforums.com/evo-4g-all-things-root/348211-quick-guide-rooted-stock-2-3-rom.html
It states the following:
Stock 4.22.651.2 ROM, rooted and ready for your flashing pleasures. This is a completely stock ROM that has had nothing done to it outside of rooting, zip aligning and de-odexing. As always, create a nandroid before flashing.
Nandroid - is this when you go to what I think is called the HBOOT menu (pwr off then vol down + pwr) and select the restore/backup and restore/etc - I have done this and now have a clockworkmod folder on my sdcard with what I believe is a nandroid backup right?
Stock Update
Stock ROM with SU Fix - No Wipe Needed If Coming From A Stock Sense ROM:
4.22.651.2 Rooted & Odexed - updated 06/05/11
4.22.651.2 Rooted & De-Odexed - updated 06/05/11
From what I've read I beleieve that I want the rooted and odexed version as I DO NOT intend on applying any themes to my EVO at this time. However, of particular interest is the

bit. In the conversation at the beginning of this post AndroidSerpent says
4) Go to recovery wipe data in factory reset, wipe cache, wipe dalvik.
and is told that he/she is right on the money. Seems to be contradictory to what the guide states, no?
Further down in AndroidSerpents post it states
6) Reboot system and then go through the entire process of starting up phone like if I had just bought it. Right?
which seems to me is contradictory to the guide's claim that
Flashing the ROM
Most of what you'll be doing will be done through recovery. So play around with the menus in the recovery image to see what options are there. Start off by doing a NANDroid backup. Since this is a quick guide, I will assume you know how, or can find out how. Next, wipe dalvik-cache. You don't need to wipe data or cache. Now you are ready to flash the ROM. The ROM contains the stock OS (w/ superuser) and stock kernel. All of this is done from the recovery image.
When the flashing is done, you can reboot and see if it worked. Take a quick look to see if your data, apps, homescreens are still there. They should be. If you like what you see, you can stop here. Having the most updated radios is not essential for upgrading to this ROM. If you want to flash radios, keep reading.

It seemed that AndroidSerpent was coming from a similar setup as mine being a rooted stock rom right? Am I correct that the two refrenced articles show contradictory info? Which one is right? Basically, I am trying not to brick my EVO and would be just tickled if after flashing the rom I still had all my stuff rather than be back at factory default but with GB. Guess I'd just want to know what to expect however these two articles cause me to think "To wipe or not to wipe, that is the question" (okay, cheesy but you get the point).
So ultimately:
1. Do I need to wipe first or not?
2. Do I have the appropriate just-in-case backups made (TB and Nandroid)?
3. Is my current setup a rooted Sense rom as I described above?
Any clarification would be greatly appreciated and I truly hope this helps anyone else who may have had the same questions. Look forward to hearing from everyone. Apologies for the novel...perhaps a bit long winded but I wanted everyone to see where my thought process was coming from.
Thanks again.
