[Q] Flashing HELP PLEASE!!

Hi,
This is my second time flashing a rom. I own a rogers captivate and I rooted and flashed to Darky's v7.0 (2.2 Froyo) NO WIPE.
I want to change the rom to Doc's ROM JPY V6.2 CE.
All i know is that I have to copy the .zip folder in sd card folder and flash it using rom manager. Do I have to do the same to flash with this one?
I have read all over the forum and I read that I am supposed to flash back to stock 2.1 and then flash again to a different rom(any other rom). Someone also told me that if I have a NO WIPE version of rom installed then I don't need to flash back to 2.1. Is this true? Can someone please confirm this?
1. Should i just download the rom and just flash through rom manager(if yes, then skip q#2) or change to stock 2.1 first?
2. If i have to change back to stock 2.1, i think I have to use something called ODIN. Can someone explain me the process please? and I dont know where to get stock rogers 2.1 rom. I looked all over the forum.
3. I do not want to overclock my phone cpu. The main post on DOC's rom says that I have to flash a kernel through CWM after first boot. I dont know what CWM means or how to use it. Any instructions?
4. Should I install the Wipe version or the NON-wipe version? and what is the difference? I like changing roms once in a while and I might change it again but I dont know which one I should use.
5. Is this a 2.1 eclair rom or 2.2 froyo? How do i figure it out without installing?
I would really appreciate if anyone can help me with these questions.
Thanks a lot.
I have always just booted into recovery mode with CWM and flash the zip that way as it works for any rom i have tried so far. I have rom manager but never used it to load a rom since CWM works flawlessly everytime for me.
The simple answer is if your changing ROMs (i.e. Cognition to Perception) - should flash back to stock then load the new ROM.
If your just updating an existing ROM and it has the "no-wipe" version? Then you should be able to run the *.zip provided following the instructions given (most likely through ROM Manager/CWM)

I Have A HTC Hero But I'm Pretty Sure It's The Same....
I'm Not Sure I'm Understanding Your Question, But I Think You Want To Get Back To Your Stock ROM & Flash A New ROM Correct?
If That's It?
You Can, But You Don't Have To Convert Back In Order To Flash Another Rom.... Just "Wipe"
System/Cache/Dalvik Cache,
& Install The New Rom!
You Can Always Restore Back To Your Stock Backup!!

No you can not revert bacj to your stock 2.1 from 2.2 using clockwork with a captivate
Can you explain how to wipe system /cache/dalvix cache or post link i googled it but found nothing with step by step instructions. I would like to try this before odin. Also why does it let you create a back up of 2.1 rom if you cant revert back there from 2.2 then whats the point of backing up 2.1 in the first place. Just thought you could do that instead of odin after reading a post which I was going to post the link to here but wont let me cause Im too new.

I do not recommend flashing phoenix over cognition without a flash to stock, but if you want to try, you can.
Cognition uses voodoo. First thing you should do is disable it.
Find voodoo file in your internal sd. Create a folder in side voodoo folder named disable-lagfix. Reboot phone.
Ok its disabled, but If Odin is the best way to go maybe I should try it but just been reading about higher risk of bricking phone using odin. Just really want to try different rom because cognition it smooth as butter but battery life is killing me compared to stock and yes I tried the charging battery to 100 then unplugging shutting down charging to 100, reboot, shut down then to 100 again no help. Anyways if I use Odin does voodoo have to be disabled also.
Pull your battery. Obviously power off first. Under battery is a build number, mine is 1008. Tell me yours
mine is 1010
Odin may be difficult to use. You may want to research your build more. Anything over 1008 is where odin is an issue
What is your base
Settings, about phone, bottom
Damn i didnt want to hear that,Says baseband version I897UCJI6 is that it.
Yes that is it.
Being on build 1010 I an not comfortable with telling you how to proceed. You need advise from someone who flashes with that build. It behaves differently with odin. I am sorry. Search build 1010
Ok thanks for your help, Ill look around
If you've never flashed with Odin one-click before, try this instead to avoid any risk of bricking (very likely on some build 1008-1010 phones that don't run JF6 stock):

Me And several people I suggested it to. But now I have a batch 1009 Captivate (traded in mine because of random shutdown issue).
saved my cappy once
I guess I'm confused...is odin really necessary at all for him? If he disables voodoo lagfix, and clears dalvik cache, he should be able to flash over the top...correct?
I flashed cognition 3.02 direct to andromeda 2.0 via cwr and did not clear dalvik or disable lagfix (since cog and andromeda both enable voodoo)...no problems for me.
Maybe it's different/more complicated flashing over the top to the ROM he wants to go to though...

Flash Custom ROM from Stock 2.2 or 2.1?

Hey Everyone,
From my reading of posts everyone seems to recommend flashing back to stock before flashing a custom ROM.
The Captivate I obtained from Rogers already had 2.2 Froyo. Will I be able to flash a custom ROM as is (since I technically am at stock) or will I need to downgrade to 2.1 using the 2.1 Rogers ROM posted on the wiki?
Thanks in advance
No, you should be fine to flash new ROMs onto it. Just root yourself, get Rom Manager, put ClockworkMod on it, reboot into Recovery, and you're done!

DISCLAIMER: I don't know anything about the Rogers Cappy.
The US at&t Cappy running 2.2 has 3e recovery which checks signatures on a file you are trying to flash. That is why venomio recommended installing Clockwork. However, it might be easier to use Odin one click to go back to 2.1 and flash from there. Then you do not have to worry about trying to get ClockworkMod installed on 2.2 (it is not a very straightforward process).

follow all the advice in the wiki, i re-wrote it last month! read! learn! brick! and learn some more!
you have 2.2 so you have 3e recovery with signature verifacation (mentioned in wiki) that is the only extra hurdle you will have with flashing over 2.2. you will have to fix that before rom manager will be able to install clockwork. **after you have a custom rom with clockwork built into the kernel you wont need to reinstall rom manager.

yes but see above ^

[Q] Stock rom and kernel?

I have tried to go back to a stock rom so warranty is valid, but not sure if all is okay
ANDROID VERSION 2.3.3
BASEBAND VERSION S5830XWKP7
KERNEL VERSION [email protected]#1
BUILD NUMBER GINGERBREAD.XWKPO
can somebody tell me if this is all stock? not sure about kernal, I want to take phone back to shop for repair. Any help very appreciated
If you flashed via ODIN then yes it's stock.
Boot into recovery check you have the stock recovery too.

Hi!. I recently flashed my froyo Ace to LeWa ROM but since I need to revert back and install the stock ROM in GB.Can anyone redirect me to the appropriate post please. Didn't do backup for original rom as I thought froyo is much outdated for a armv9. Thanks in advance.
