Newb Q's before flashing for the first time

Ok, so I'm thinking about finally flashing a rom because I am tired of waiting on the official update, probably using cog. However there are some things that I want to make sure I understand before I start flashing.
(1) I want to be able to go back to this official jh7 in car something arises. If I am not mistaken, I can do that through clockwork recovery by using "flash clockwork mod". If I'm correct this will create an update.zip file that can be reinstalled by going to phone recovery and reinstalling packages. If so, what all does this back up? Will it be like a stock jh7 with only default apps and settings? Do I need to un root and un-lag fix from what I did through ryanza oclf?
(2) do I need to un root and un lag fix oclf to install a rom.
(3) I'm pretty sure that it will not have my apps/settings from now, to get these I must backup using titanium, and reinstall from titanium on new rom correct?

Great place to start is with Cognition Roms. Have run several and currently on 2.3b6. It's fast and the Froyo touches make it worth NOT waiting for an official update.
1. Once you are rooted, install Rom manager, and flash Clockwork Recovery. Reboot into Recovery from Rom manager. There are several options in recovery but toggle to backup and restore and then select backup. Doing this will create a nandroid backup of your phone as it exists now. This file will be stored on your phone's external sd and from there I always copy or move mine to my removable sd card. If you ever want to restore reboot into clockwork recovery, toggle to backup and restore, then restore and find the file (would rename it if i were you) then restore.
Another great tool is the Odin 1 click restore. If you get your phone jacked and can't get into recovery this will take you back to stock with no root. Cog recommends flashing back to stock with Odin and then rooting again before flashing another rom so it would be good to learn this method anyway.
2. Can't flash a new rom without being rooted. I would uninstall the lag fix also. There is a lagfix built into the current Cog rom called Voodoo.
3. Backup up apps with Tit backup but when you restore, restore the app only and not the data. I backup my text messages and call log with sms backup which works pretty well and restores easily.
From your current state. Download the latest cog rom 2.3b6 from your phone's browser and rom manager will pick up the download. Go to rom manager when it's downloaded, click download rom, find the zip file, wipe date, wipe cache and watch the magic.
The cognition wiki explains the steps as well.
The water's warm so jump on in.

Thanks for your help, I'm anxious now. If I want to restore a game amr its save games don't I have to restore data too? And on the wipe data and write cache, by that you mean from clockwork recovery? Thanx again for your help

I've read it many times in the Cognition forum that restoring data with apps can give you problems. I have done it in the past with no difficulties on some apps and had issues with others. You can try and see what happens. My kids always get upset when I flash a new rom because they have to start Angry Birds from the beginning again. I'm not an expert by any means but you might want to search the cognition thread and get some second opinions.
You can flash a new rom from rom manager and since you are at stock with root is probably the easiest. Go to rom manager, install rom from sd card, you will then be taken to your sd file directory, go to download, then the cog file you want to flash. You will get a prompt to backup existing rom which you can do if you haven't already done your nandroid backup but if you have a backup already then you can leave unchecked. You will also get a prompt to wipe date and cache which you want to do. Rom manager will take it from there. Phone will go into recovery and you will see on the screen what is happening as the file is downloaded and everything currently on the phone is wiped and will reboot.
Note on Tit backup - I would copy your backup file to your external sd. My files, long press tibu, copy, go to external sd, paste. Little extra protection and only restore apps and not system stuff. Apps are always a certain color in tibu.

Ok, so when I try a remove oclf it gives me an error dating I have 312 mb free on rfs, but 662 mb used on ext2, must free up some space.
Do I delete some stuff on /data/data to free up some space?
Sent from my SAMSUNG-SGH-I897 using XDA App

Not sure on that one. I had oclf installed once and was able to uninstall pretty easy in Ryan's program. It might not matter if you are wiping data but DG has posted several times about disabling lagfixes. You can always give it a shot and then restore your backup if you have issues.

[Q] ODIN, Download Mode, JH7, Modems, Kernels... somebody school me

I've searched and read FAQs a lot already. I read the threads that XDA suggested before posting this.
I've been doing a lot of reading and I'm a little fuzzy. Want to root my gf's AT&T Captivate (JH7) and install Froyo for her but still a little unclear on exactly how everything fits together.
From what I've gathered so far I can use the update.zip method to install Clockwork Recovery and make a nandroid backup of her current configuration without even rooting it, right?
Then can I just flash whichever ROM I want? Will the ROM.zip update her to the correct modem/kernel at that time?
About using ODIN to restore - do I restore to the version she is on NOW or the version the phone originally shipped with, if different? And do I REALLY need to ODIN restore between ROMs or is a full wipe with CWM recovery enough?
Also read that CWM recovery doesn't work with Froyo at this time so can't do nandroid backups of Froyo ROMs?
Somebody catch me up... with my mt3g and mt4g I'm totally comfortable but this stuff is confusing me. I'm fairly comfortable with adb and already used it to sideload an app for her without rooting.
Thanks for your help guys.

I'm pretty new at this too so I'll try to answer what I can.
Before you try anything, just make sure you can get into recovery and download mode.
Recovery:
- Hold Vol Up + Vol Down + Power button.
- from adb type reboot recovery
- from Rom Manager, select the Reboot to Recovery option.
Download
- Hold Vol Up + Vol Down and insert the usb cable. This works for me. Getting Odin to detect it can be a bit tricky. I usually start Odin first, then connect phone.
- from adb type reboot download (I think)

Not sure to be honest. The way I do it is that I install Rom Manager from the market first. It will ask you for root though. I like this way better as you can download and install the appropriate update.zip from the app. Rooting is very very easy. You can use this tool:

To be safe, I only try ROMs that I find in the Captivate Development sub forum. Most of them can be installed with CWM. Place the *.zip in the root of your internal SD card, reboot into CWM and select the install .zip from card option. Don't freak out.
There is also a way to flash roms from Odin but I've never tried it to be honest.

I believe it will restore to Samsung's stock version (I897UCJF6). Check this thread: http://forum.xda-developers.com/showthread.php?t=731989
Remember that this is only for the Captivate. It is safer to do a full restore whenever you are trying a new rom. The only exception, I think, is when you are upgrading versions (say, Darky's 7.8 to 8.0)
Also read that CWM recovery doesn't work with Froyo at this time so can't do nandroid backups of Froyo ROMs?

I always install it using ROM manager and it works fine.
Now, from what I've been reading and doing this week, I learned that apart from the ROM, you can also flash the kernel and model separately, in case you have specific needs. For instance, I flashed glitterball's kernel to overclock the phone. Just remember that 2.1 Roms need 2.1 kernels and modems, the same applies for 2.2. Here is a list of modems: http://forum.xda-developers.com/showthread.php?t=835272
I'm currently trying out the TLJL3.
Remember that there are many ways to get to Rome. Also, use Titanium Backup to save your apps.
tl;dr:
1. Root.
2. Install CWM.
3. Verify that you can access recovery and download mode.
4. Download ROM (CWM .zip installable).
5. Read read read.

Hmm... Most of your answers can be found in

The ROM file would contain a kernel and a modem that will update her current kernel and modem. She can flash the kernel and modem of her choice after installing a custom ROM without breaking anything.
For Backing up use Titanium Backup, u need to ROOT your phone using directions in the earlier link provided.
When using custom ROMs it is always better to do a full wipe and flash to stock and master clear, i.e JF6 (using Odin one-click, or Odin with 3-button) or JH7 using the DG version.
You can follow
http://forum.xda-developers.com/showpost.php?p=10056254&postcount=36
Update.zip file once installed would load CWM from which you can install custom ROMs. Once you install custom ROMs, they are always rooted, and you needn't root again. It's a one time thing.
Hope this resolves everything..

Thanks for your replies, guys, I'm actually very familiar with rooting and flashing. To clarify, I already know HOW to install a custom ROM, that's not the issue. I'm more concerned about compatibility once I start installing custom stuff, and about UNROOTING if I need to. It sounds like if all I'm doing is installing a custom recovery and then a custom ROM, I don't really need to worry about it.
I always opt for manual method through recovery as opposed to Rom Manager.
I would use SuperOneClick for the stock ROM as I've used it before without issues. Most likely I would use the update.zip method to install clockwork recovery so I can make a nandroid backup of her completely unrooted stock setup before proceeding.
I can get into stock recovery just fine but haven't tried download mode yet.
And yes I would ONLY flash ROMs for the Captivate specifically, unless someone manages to complete a port for Sense.

Sounds like your good to go then.
... and Odin is just the cheap and easy method to return the phone back to stock.
So if you ever need to give it back and need it restored this is the easiest method to do it. But I would suggest formatting the internal SD Card to make sure there are no remnants of you playing around with the phone.

Agreed, will definitely do that.
I also heard that when using ODIN to restore to JF6 the OTA update to JH7 won't come back on its own?

lol yea.. but it doesn't matter unless you were wanting to keep it on "stock".
If your flashing or returning the phone your ok with keeping it on JF6.

If your phone came with JH7 and you have issues with Odin one-click, you might want to look at this guide, it has worked great for me and many others:
http://forum.xda-developers.com/showpost.php?p=10056254&postcount=36

How do I know what build number her phone is? I see references to build number 1010, but I don't know if this phone CAME WITH jh7 or if that was an update. I bought it used. If I try to restore to JF6 will that brick it??
EDIT - found it. She's a 1007. So if I used ODIN-3 to restore to JF6, how do I get back to JH7? Reading elsewhere it seems that a nandroid restore won't include the baseband?

Download the Mini Kies from here Download Center for SEG-I897ZKAATT.
Make sure the phone asks for USB on connection and select Kies mode when you plug into pc. Then open Mini Kies, it should recognize your phone and tell you an update is available. Follow the instructions from there.

Ok cool, thanks for your help! Already downloaded Kies from the Samsung website.
About to flash her phone but saw something somewhere about backing up some *.nv file to preserve her IMEI# and stuff? Can you link me to a guide on that? Can not for the life of me remember where I saw that.

[Q] CWM flashing without ODIN

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?
3. Save /efs folder?

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
zug

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
zug

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 ;(

[Q] Installing Custom ROMS, why stock?

Simple question. If answered in another thread, please give me a pointer. I searched, but couldnt find an answer. Here is the question.
Why do we have to revert to Stock 2.1 before flashing a custom ROM? Why can't we flash a 2.2 custom ROM over another 2.2 Custom ROM? And finally, is there a CWM flashable version of stock 2.1 with root and cwm pre-installed?
Thanks.

before a lagfix was adopted as "standard" by the dev community this was necessary to reset the phone file system to n unmodified state. Now that all the devs are using the same type of awesome lagfix, reflashing to stock isn't really necessary anymore, IMHO. I never do it anymore. I just do a wipe user data from my recovery menu and everything seems to work fine.

The answer is not simple.
You do not have to flash stock. It used to be more needed. Devs still say so, but I believe that is largely to problem shoot issues from the get go. Threads are cluttered with comments like omg my phone is possessed. Well what were you running prior, and what was your setup? If stock well we know what was what. If ulk kernel with ext 2 loop, then yes there could be issues
Flashing stock at this point is just as risky, if not more risky then flashing directly over. If something feels wrong and you can't fix it, flash stock\master clear start over

So in essence, we can flash fine over an existing ROM and if there are issues, better go to stock and flash from there. Am I right? Can you list the steps you take to flash a new ROM without going to stock? Will there be issues if lets say I flash a 2.2 ROM over a 2.2.1 ROM?

I.do this but it may be redundant
Backup apps
Dl rom
Boot recovery
delete cache
delete davlik cache
Flash rom
delete davlik cache
Boot

I never did flash back to stock. I failed. Odin would not connect.
But for you guys out there - there is a way to bring recovery menu, that's what saved me.
Remove SIM and SD card.
Power+VolumeUp = reboot from any locked state
Power+VolumeDown=reboot into recovery
Power+both Volumes=download mode, never worked for connecting Odin, I could go there from Recovery
So my sequence:
remove old backups
create new backups
download ROM
boot into recovery
flash rom
clear cache partition and dalvik cache (probably the same)
run fix permissions
reboot

I think for most new ROMs that take advantage of the updated 2.2.1 filesystems you don't need voodoo or any lagfix. Can't even remember the last time I used ext4 when using speedmod kernel and JS3/JS5 Rom. Makes it easier to flash new roms when you don't have to worry about corruption.
But flash back to stock clears out any unnecessary gunk that could cause 90% of Force Closes and random vibrates on boot

I always thought of it as installing a new operating system or a different version of. It. Cming from the same roots of the ROM or OS, you can just install a different, major update over it (Different ROM) and be on your way.
However if sonething is built differently from the start (Windows and OSX), you cant just install right over the other because there are problems.
I always start back at the beginning because it onky takes a few minutes extra and it makes the phone a whole lot faster; you clean out alk the gunk and unused folders and whatnot.

you definitely want to do a master clear if you do not start from stock, since there are some caches on your sdcard may ruin your new system.

Does anyone know how to do a Master Clear with Odin3? Or is there some other way we can do it without Odin3?
Thanks.

I use the oneclick odin to do master clear. The master clear works on i896 too.

Help - How do I install custom roms step by step on my LG Thrill

Ok guys first of all I am sorry I am a noob when it comes to "flashing" and "custom roms" and "backups" and I have been searching the forum and can't find a simple straight answer or instructions on how to install a custom rom on my LG Thrill step by step. So I am sorry for this thread id there is already on for it. I even googled it and I keep getting different answers and I am more confused then ever. Some say use clockworkmod and some say it won't work for the thrill...I also don't know how to make a backup of my current rom which is the GB 2.3.5 upgrade v20p my phone is rooted and I have titanium back up pro installed. Can't I just make a backup on titanium back up? or is this a different type of back up? Anyway I am looking for a straight forward step by step guide on installing a custom rom on my Thrill from start to finish. Any help would be great Thank you and sorry if this has been answered a million times and if this is the wrong place for this post

Clockworkmod Recovery works just fine.
Clockworkmod ROM manager doesn't work as it should. So, you're rooted, so all you need to do is install CWM recovery. After that, just put the ROM you want on your SD, boot into CWM recovery, and choose install zip from sd. Its always best to wipe data and clear caches before or after flashing. Also wipe dalvik cache under the advanced menu.

Looked for clockworkmod recovery on the android market and can't find it. I saw all the other apps that cloclworkmod makes and still nothing they do how ever have recovery apps for specific phones like Droid X and Droid 3. How do I wipe the data and caches? I did wipe the dalvik cache using titanium backup though
