Everytime I flash I go back to stock unless its a same rom.
Ex. I was on darky 7.2 I just downloaded the rom on my phone via dolphin. Just used rom manager to get 8.0.
But can I do this for all roms? I'm kinda confused cause some say you can and some say you can't..

You do not have to. You should disable lag fix, clear cache and davlik cache, prior. Flashing back to stock is cleaner, especially if you are going from a rom with one base to one with another. You can always try without going to stock and flash stock if something goes wrong.
I never do. I just boot to recovery and flash. If I'm using a different kernel I'll reboot to recovery then check my lagfix options and then reboot.
No need to flash back to stock. If the ROM is a 'no-wipe ROM', install like you normally would through CWM/Recovery. If you have problems, or if the ROM is a 'wipe' ROM, clear cache and data in CWM and install. If you still have problems and nothing else seems to be helping, try reverting to stock and starting fresh.
Reverting to stock between ROM's is an unnecessary extra step that generally adds the risk of Odin failure/incompatibility (which can result in a soft-bricked or hard-bricked phone).
Scenario:
- I'm running Phoenix 4 ROM
- I want to try another ROM
- I have a copy of the JH7_OTA-1.zip
Can I just use ClockworkMod Recovery to flash the JH7_OTA ROM, then do a master clear from the phone and then apply any ROM I want?
Would that not accomplish the same thing as putting the phone in download mode and doing a stock restore via ODIN, followed by a Master Clear, and then flashing any ROM?
Can someone clear this up for me because it seems that both methods accomplish the same thing. They restore your phone to factory stock ROM as it's suggested by majority of the ROM before applying them.
Thanks
You can go from one rom to another without flashing stock.
I just went from doc jpy base to andromeda armani base. All I did was disable lag fix and kernel tweaks then flashed
I did so knowing I had odin just in case
What mcord11758 said except you don't actually need to disable anything. Just flash.
So that's the confusing part because:
Cognition ROM used to saynow there is just a DL link)
"flash back to I897UCJF6 (Recommended)"
and
How to flash PHOENIX Roms:
"1. BACK UP!!!
2. Use Odin One click to Flash Stock
2a. Wait for it to reboot and then re-enable debugging, hook phone back up to pc and Master Clear"
I got the concept that if running any lagfix it's best to disable it when updating the same ROM to a newer version but when doing a factory ROM it wipes out the ROM contents including the file-system format be it EXT4/EXT3 back to the Samsung RFS.
I would love to hear from one of the developers but I couldn't ask this question in the Dev Forum due too my n00b posting status.
Thanks for anyone who takes the time to provide some insight.
Phoenix and cognition both use ext 4 filing and the clockwork recovery built in understand it.
You have no less risk flashing jh7. in essence you are doing the same thing
flashing stock was more necessary when recovery could not understand ext 4. Today you can change to three different kernels in one day without ever disabling a lagfix

The partitions get formatted either way (unless it's now wipe, in which case I guess data and datadb don't). If are running ext4 and your new kernel supports ext4 then why disable it?

Thanks, that was the answer I was looking form I didn't exactly understand that the restriction was the recovery rom. It makes sense.
Hi,
I'm researching flashing via CWR, ROM over ROM without flashing to Stock via ODIN. Specifically, I'm at Cog 3.02 with "base" Cognition Kernel/Modem thinking about going to Andromeda...both employ Voodoo/EXT4, so shouldn't need to disable lagfix (I think?)...
I read at this link (apologies for spaces, but I'm new so can't post actual links): h t t p : / / forum.xda-developers.com/showthread.php?t=900463
a spirited debate starting about page 4 that flashing to ODIN is effectively doubling your chances for a bad flash, and that recovering a bad flash via CWM is far easier (just try re-flash again...and again(?) until fail back to trying ODIN) than recovering a bad ODIN flash.
If that's true, what prep should I do first via CWR?
1. Andromeda says requires wipe, does ROM install do this or do I do it via CWR first (wipe data/factory reset in recovery)? How 'deep' is a wipe...what do I need to save prior to this?
2. Wipe Dalvik Cache and/or wipe cache partition?
3. Save /efs folder?
4. Aside from TiBu backup to PC, am I missing anything else to save? I forgot to save my Android ID on my first flash, so it's my understanding I can only get that back via flash to Stock...I'd prefer to only go to ODIN if I have to.
Another question I had was regarding nandroid. I made a nandroid backup right after flashing to Cog. Do I really even need this? Since I haven't changed kernel/modem, wouldn't I be better off just flashing my initial Cog zip file?
Finally thanks to all who make this site kick_ss. Connexion2005's videos are indispensable for a newbie like me. People actually answer questions here, and the Devs suceed in delivering onto us a wolf in (out of the box) sheep's clothing...something AT&T and Samsung have failed to do.
Cognition 3.02 is my first and only custom ROM and DG, you have literally saved me from making my phone a brick the old fashioned way: throwing it against a wall. Running flawlessly since Jan 17th...at the same time, I am eager to see what else is out there, ***safely*** as possible.
Thanks in advance.
Since they are both ext 4 you should be ok.
The rom wipes, I clear davlik cache before flash and after, but there our no good reason as to why
Efs files, do you use kies? If so you may want to back them up, if not don't worry, I have never backed then up
Odin flash is not needed but my opinion is you should know how to use odin prior to flashing. Why panic to figure it out if something goes wrong,?
NANDROID only needed if youare going back to cog and after you have flushed the rom you want to restore settings
I think I got everything you asked
Thank you.
So really just the Dalvik cache wipe in CWR prior to.
Kies...soooo failed ever getting that working, and don't seem to need it.
Yeah I actually flashed ODIN1 unnecessarily prior to my flash to Cog. I was at stock and somehow thought ADW would mess it up...rook. I have build 1006 so good to know ODIN's there if I need it.
Re: Nandroid, but if I kept the initial zip for my flash to Cog wouldn't I just use that? Or does Nandroid do better job of ensuring good flash back to what I have right now?
Not familiar with flushing...Would I be able to restore Nandroid directly on top of ROM I'm switching off of?
Thanks again.
OP,
You'd double the chance of failure if all else were equal. I don't have statistics, but I have no doubt that failures happen far more often with odin flashes, though.
1. Andromeda says requires wipe, does ROM install do this or do I do it via CWR first (wipe data/factory reset in recovery)? How 'deep' is a wipe...what do I need to save prior to this?
2. Wipe Dalvik Cache and/or wipe cache partition?

The ROM install script does the wipe. This simply means all your apps and data will be erased (your pictures and anything on the internal and any external sdcard will not be deleted).
I never wipe the dalvik cache or cache partition before flashing. I only do that if I'm having issues like FCs (sometimes happens after a bad theme install, for example).
You probably should have backed up /efs before flashing anything, but that's not to say a backup now isn't a good idea. You only need to do this once.
If I recall, you do need to flash 2.1 to get the ID back. I'm not 100% sure there isn't another way.
WRT the nadroid backup, you don't really need it. What I do is keep 2 or 3 good CWM flashable ROMs and the CWM update.zip on my sdcard in case of problems. I also keep TiBU backup of my stuff there (which I also occasionally backup to my PC just in case my sdcard gets wiped for some reason).
One thing I would suggest is to be sure you have working button combos in case you ever need download mode (hopefully you never will, but it's always possible). If you don't have that, there is a clockwork flashable fix or you could just flash cognition or perception once and then flash whatever you want over them (you can do both flashes all without ever leaving recovery). That should fix the button combos since DG's ROMs include a good sbl.bin (I'm not a fan of that inclusion, but it is useful in this case). Since you are running Cog, I assume your download mode is already working.
Thanks opcow.
Yeah I made sure I could get into d/l and recovery mode with button combos before I even rooted.
So would you ever use a Nandroid backup if you added a different kernel/modem to a ROM? Or would you just go back to the initial zip and SGS Kernel to flash kernel/modem? I haven't done kernel flash...yet...

If the ROM you were running when you backed up is compatible with the new kernel then I don't see why there would be a problem. I don't do it, myself, but I'm not sure why. Maybe it's because I have the paid TiBU and I just use that.
Thanks again...
Yeah I bought full TiBu, so obviously that should work for the apps/data.
Did some more digging tonight and apparently Nandroid backup is ROM only, not Kernel...So seemingly would need to be on same Kernel at least to do proper Nandroid restore.
...that being the case, I guess I don't understand why people stress importance of running a Nandroid prior to and/or post ROM flash...am I missing something?
If you like a rom and set everything up but want to try another doing a nandroid allows you to restore once you flash the rom again.
Also good to run nandroid on new flash, so if you play with themes and something goes wrong you can restore
That makes sense.
Showing me newbie-ness since I haven't played around with themes yet...
...Figured I'd at least get 2nd ROM flash out the shoot before playing with kernels, modems or themes...
This thread is helpful for me. I appreciate your time.
This is along the lines of the question that I was going to post so figured would ask here. I too am considering trying out the new Andromeda. I am currently using Cog 3.04 and want to test out the new Andromeda. The TiBu I have right now is from when i was on stock as I just recently purchased this and Cog was my first flash.. Would i want to continue to use that backup when i flash to andromeda, or would it be better to run a full backup with tibu while cog is on there and then flash to andromeda and use the cog backup??
also,, from above, i could possibly just skip the step with odin and go straight to andromeda? or do I need to run odin and put it back to stock before going over to andromeda?
thanks

Hey Zug,
Just flashed andromeda last night via method outlined above...did not revert to stock at all (no odin). Only issue thus far is market only showing very few installed apps under 'My Apps', but I think this is a common issue. Will research solution tonight (I did have some issues getting back all apps from TiBu, but after I restored missing apps twice and rebooted a few times they all appear to be back). Also my simi clock widget comes and goes, not sure why...might clear dalvik cache to see if that helps.
Regarding TiBu, it saves apps and data. It is not ROM specific...you just back it up, then after you flash new ROM you restore missing apps with data (do NOT restore system data).
EDIT: Resolved the My Apps Market issue (only a few were showing after flash) by going to Settings, Applications, Manage, go to Market, Clear Data, reboot. Search is my friend.
i897 running Andromeda 2.0
Thanks Madtowndave.. i might give that a try.. so, since my phone is rooted and what not, i can just go to the guide and start at the portion about puting the new rom on the sd card, rebooting it and what not in recovery and select that zip and flash it right ? (well condensed version of course) and it should all be good?? guessing if this fails can always use the odin and wipe it and go back?
since i added a few new apps, guessing then that i should use tibu and go ahead and reback up everything since this rom does the master clear and then reload them right?? and hate to ask.. but how do I do the nandroid? newbie still to android and i know that just backs up the rom, but is it a app to dl from market? was fishing around in phone and didnt quite see it yet. .but figured i would do a nandroid in case i want to go back to cog.. this smart?
thnx again

I think most of your questions are answered by others in this thread...
One thing I noticed last night is that I only got red (voodoo) cwm recovery menu via 3 button or long press power and reboot to recovery...when I rebooted to recovery via ROM Manager, I got the green cwm recovery menu. Not sure if this matters, but in another forum (on Vibrant phone, our sgs cousin), they said to flash ROM via the red voodoo cwm menu (since cog and andromeda both employ voodoo you can leave it enabled).
Nandroid backup you can do either from ROM manager or in cwm recovery...
Also andromeda wipes the system data, not a master clear...your data on 16 gig internal memory should not be affected, but is very good idea to backup everything to pc per the flash custom ROM guide.
i897 running Andromeda 2.0
Thanks again madtown.. going to give it a try now.. as andromeda just finished DL'ing
Good luck, hope it goes smooth for you as it seemingly has for me...Feel like a bit of a heretic for not flashing to odin first...maybe I'm just lucky.
i897 running Andromeda 2.0
hmm. ok. .so did the reboot to recovery and installed andromeda.. did it take a tad bit for yours to boot into the phone portion after it got to the andromeda screen?? mine seemed like it was hanging and was about to worry.. but finally booted in.. so figured would see if yours did too? .. gonna test stuff out now and restore tibu
Yeah, did for me too...and yes I was worried. Pretty sure this is very normal on first boot into new ROM in general. Like I said, TiBu was a bit cranky for me and required 2 restores and reboots...
Really enjoying this ROM, btw.
i897 running Andromeda 2.0
yeh.. im still doing the install from tibu (getting paid version after tomorrow since payday since im hating have to select install for every app ) .. and then will reboot and test .. though one thing ive noticed that is diff from the video is the lock screen.. in his review it was the lock button and he swiped it up.. mine is set to a puzzle piece by default?? any idea??
edit.. k mine was a 1st time go for apps restored with tibu .this is pretty nice.. it does appear to be a lot faster/smoother than cog so far.. though the Keep the lights on app should keep my bottom buttons on all the time right? least thats what i thought i was from the video and mine seem to still fade out.. even though i hit the app and it said it was enabled..
changing unlock is in settings, display...
Dunno about lights, mine just worked. Make sure service started and reboot I guess.
i897 running Andromeda 2.0
ok.. that was what it was for the lock part.. thnx .. didnt know that was there for those 4 choices.. thought only could do the none, pattern, pw etc..
everything went fine until i decided to load my contacts/sms etc from tibu.. now when i rebooted to add them, i keep getting the message "Sorry, The application Swype (processcom.swype.android.inputmethod) has stopped unexpectedly.. please try again" constantly getting things like that about swype.. any idea what happened or what i need to do?
edit.. sucked it up and re-flashed ;( will just sync contacts and deal with the ones missing for now ;(
I read as much as I can about installation of a custom ROM. I think I'm confident enough to do it now, but I just want someone to review these steps before I start.
I have a Rogers I896 currently running the stock froyo that I upgraded via Kies with a build 10.10.
Because this is on a build 10.10 I can't follow the steps vertabim with the guide in the android development forum.
1. Root with SuperOneClick
2. Titanium Backup
3. Use Odin3 v1.7 or later to restore to stock with this http://forum.xda-developers.com/showthread.php?t=905042 and the 512 pit file. (I understand this is unnecessary as I'm already stock, but in case I need to revert back to stock from a custom ROM, this is what I'll do)
4. Reroot with SuperOneClick
5. Get the ROM and put it in the root of the phone
6. Download ROM Manager and install Clockwork Recovery
7. Boot into recovery and install zip from SD card and choose the zip file that I downloaded.
8. Titanium Backup to restore
Please let me know if I'm missing something. I think I read something about Nandroid backup somewhere in the forums. I'm not exactly sure what that is and it didn't really say that in the guide. Should I do that and how do I perform that?
I'm thinking about installing either Paragon, Serendipity, or di11i. Perhaps someone can also maybe list some differences, issues, pros and cons about these ROMs.
Thanks in advance!
your steps are good enough for you to flash to a new rom.
You may have trouble with installing Clockwork. If you do, follow this link.
Also, once you reboot into clockwork, remember to do a backup of your current ROM and move it and your TiBu backups to your HD. Clearing your cache before you install your new ROM isn't a bad idea either
Goodluck!
Is clearing cache done in the clockwork recovery? I notice an option for "clear download cache" from Rom manager. Is that the same thing?

I do not think "clear cache" is necessary when you install a new rom, since most of rom will format the related partitions first. You can clear the dalvik cache in the cwm.
A master clear is recommended since it will reset your phone to factory default and delete all the data in your built-in sdcard.

It doesn't hurt AFAIK. I do notice after restoring apps with TiBu some apps require you to clear their cache in order to work properly, so I do it as a preventative measure.
Another tip: do NOT restore all system data with TiBu after you flash!

I started on Rogers stock 2.2.
Used superoneclick to root. Installed rom manager. Used a script to modify my recovery 3e file. Rebooted into recovery. Flashed cwm. Installed my custom rom.
Pretty awesome.

Hey I don’t mean to hijack/bump the thread but I’ve got an I896 which I’m attempting to flash a custom ROM onto, but I’m a complete phone newbie and could use some assistance when it comes to clarifying some instructions. This thread seemed to be the most “laid out” instruction guide for the I896 which I could find.
Currently my phone is running 2.2 Froyo / I896UXJL1 / Kernel 2.6.32.9 which I got via Kies early January when the update was released by Rogers.
I downloaded SuperOneClick 1.7 and rooted it without problems, but that’s as far as I’m clear/comfortable.
1. Do I need to use Odin (http://forum.xda-developers.com/showthread.php?t=905042) to restore to stock? Since I’m on the default Rogers technically that is already stock, no? Can I simply continue on from where I am?
a. If I don’t need to use Odin, do I need to make a backup with titanium?
2. Does step 6 of the OP’s list simply involve hitting the “Flash ClockworkMod Recovery” option in ROM Manager v3.0.1.0?
3. After that is it simply a matter of downloading my ROM of choice (Serendipity 5.12) and putting the .zip into my root folder, booting into recovery via the “Reboot into Recovery” option in ROM Manager, and then selecting to install the ROM .zip file?
4. Is my above three points everything I need to know or is there anything else I should know/be considered?
Also, when rooting I simply turned USB debugging on, ran the two .exe’s in order and then hit root after plugging in my phone. Was I supposed to go into download mode or anything or is that only for other modes of rooting (I have superuser installed and titanium backup was able to get root access so I assume my phone rooted properly).
That being said, I’ve read a ton of threads and a ton of stickies but things tend to seem either old/outdated or focusing on the AT&T i897, with there being limited information on a newbie friendly “explain all” way from A to B for the i896, unless I missed it. Some mention rooting with X, and using path ABC to root/flash a custom rom, and others mention rooting with Z and using patch DEF to do the same; all of which have left me feeling uneasy about flashing. ><
I'd be more then happy to provide any information in which I may have left out, and would appreciate any help I can get as I'm more then enthusiastic about flashing my first custom ROM but would like have the knowledge to do it right instead of being left with a brick. Yes, I know it seems almost all "bricked" captivates are unbrickable, though I would prefer to avoid that road at all costs either way haha.

I'm curious to know why not to restore system data?
Is "missing apps with data" ok to restore?
Restoring system data messes things up. Restore "missing apps with data" only. no system data.
If you restore system+data your home screen will fill up with force closes faster than you can clear them out, I know this Because I did it...twice, this is where my aww.W.T.F? sig came from. Don't panic if this noobish brain fart happens to you, just re-flash the rom and only restore missing apps+data as studacris said and enjoy.
Hi,
i currently have Froyo 2.2.1 + Root + Vodoo + Lagfix installled.
However, i am unhappy with the battery life with the voodoo kernel and want to get back to my CF Kernel.
I modded some of the stuff on my SGS (Camera App, Bootscreen, uninstalled some system apps).
First Question:
If i dont have any other issues, is there a reason to reformat the whole device (repart) so its back to stock like it was when i got it? I always felt better with a "fresh" installation of my windows, and somehow i feel like... how to say.. like i dumped my OS on the SGS with all the stuff i installed, reinstalled, deinstalled, flashed etc pp ^_^ But if you say, thats not an issue then i will leave it as it is.
Second Question (just to confirm what i am doing):
How do i uninstall vodoo and get back to what it was before installing vodoo? I want a fresh install after that.
1. Disable the Lagfix
2. Factory Reset
3. Flash JPY without Repart
4. Flash CF Kernel
5. Install Rom Manager + CWM
6. Install Deoexed Stock JPY Theme
7. Install Backup Apps/settings (not nandroid)
8. Profit
Correct?
Could i also restore a nandroid Backup from when i had the CF Kernel? (after step 5 ofc).
Thanks in advance
//EDIT:
To concretise my initial question:
When is repartition needed? (except when you crashed the OS on the phone )
Re partition is only needed when you have a firmware with all 3 files.. and something is corrupted preventing the phone from booting...
you dont need to do a full wipe.. you could get away with just removing lagfix and restoring back to JPY firmware... BUT doing a full factory reset would remove any unwanted things giving you that 'fresh out the box' feel... somethings tend to get left behind if a wipe isnt done.
your steps 1-8 are all in the right order you can disable lagfix thru CWM
i always do a full wipe before installing another ROM it makes me feel better
i always do a full wipe before installing another ROM it makes me feel better

So, I did steps 1 and 2, but instead of flashing the JPY i tried to flash the brand new JS5.
