I have a stock Captivate, and am new to Android OS. My understanding is that the Captivate has Android 2.1 with Samsung's Touch Whiz "blended" into it. I'm also aware that there are many custom roms that have various versions of Android with various tweeks and what-not, and to implement any custom rom, you first have to root (unlock) you phone, which voids the warranty.
My question is: Is it possible to install a basic Android (vanilla) version (2.3?) onto my Captivate without rooting my phone, or if it has to be rooted, is it as simple as just rooting the phone, and then downloading/installing the Android 2.3 source code? Or, are the custom roms necessary because they contain drivers for the various hardware components in the Captivate? School a noob please.

2.3 is Gingerbread not vanilla (if and when google ever makes a vanilla, it will be a long time from now). Anyays, you HAVE to root the phone then install rom manager from the market and install the rom zip through either rom manager or clockwork recovery (installed when on rom manager's first use).

I get that vanilla means just stock android, whether it be 2.1, 2.3, etc. I was a little ambiguous with my question, apologies.

When I root my phone, I understand that it voids my warranty, but would it prevent me from installing the mythical official AT&T 2.2 update?

So, I can use this to install stock/vanilla android 2.2 or 2.3, and it will work with the Captivate, or will some hardware not function properly?...This goes back to my original question about whether or not stock/vanilla android 2.2 or 2.3 will run on my phone without error, or if a custom rom is required to get the android OS to work with the captivate's specific hardware.

If samsung/att finds out your rooted it will void the warranty, but you can go back to stock and they won't know. You will likely have to be on stock for att ota updates to work.

First of all, make sure you can get into download mode using a button combo (see the sticky), otherwise you might need a jig if things go bad. Download mode is what is used to go back to stock prior to flashing a rom.
stock has locked down features of your phone such as: usb tethering, mobile ap, 2g/3g toggle, and more; plus stock is painfully laggy (slow)
a good rom like the one I use (see sig) has all these features working and is very fast.
Edit: I misunderstood you. No you will not be able to use your phone with android that is not specific to a captivate or i9000.
Thanks man, you deff cleared up a bunch of stuff for me. I'll prob just wait for the official release then, as I'm pretty darn happy with 2.1 (coming from a tilt2 with stock 6.5pro).
I'm starting to get the feeling that there is a better chance of having a cargo jet, full of gypsy tears and unicorn blood, fall out of the sky on my car while I'm on my way home from work today, than seeing the official froyo by this spring...
Yea.. still ongoing issues with what Samsung is releasing and AT&T keeps waiting. So we keep waiting.
And a true "Google Vanilla" ROM for these phones are almost impossible. Gingerbread will be the closest thing we are going to get to having it.
Between the Touchwiz interface, the proprietary RFS file system, and the fact that Samsung has integrated so much other bloat type crap in their OS - then fails to release the Source code so the folks on XDA can fix the mess.

So Froyo is supposed to come out in September.
I'm debating rooting my phone now but keeping the stock rom.
Will there be issues upgrading to Froyo when Samsung makes it available?
Will I have unroot, etc?
Thanks.

Anything we tell you would be a guess...
I guess better questions would be:
Does anyone plan on doing anything special when the update comes out?
Do they expect things to work smoothly?
Do you plan to unroot, upgrade and re-root?
Thanks.
As far as I'm aware, rooting 2.1 on the Galaxy S is as simple as installing a few files which allow you to run things as root, no horrible kernel hacks or such necessary. This means that unrooting is just a matter of deleting those files.
So that, combined with the way that installing 2.2 would wipe the device anyway, means I'm really not worried about installing anything new on a rooted device. It's easy to unroot 2.1 if you want to, anyway.
Is Cyanogenmod the only Froyo option for the CDMA Hero? I'm thinking of upgrading from the Sprint 2.1 firmware. I have several questions:
Really Important:
Can I downgrade to the original Sprint 2.1 firmware without breaking anything? I really don't want an expensive phone-shaped paperweight if anything goes wrong.
Can I keep the HTC sense UI (I only want the main menu dialer anyway)? I saw that thread saying Sense 2.2 is about 85% done.
Somewhat Important:
Can I install the wifi tethering app on 2.2 Cyanogenmod?
Does Sprint notice if you tether and cut you off?
Do I have to root my phone?
Isn't giving root to potentially malicious apps a bad idea?
Is giving root on a per-request basis?
Can I remove the stupid Sprint boot animation?

You are already on stock firmware. Do you mean if you go to CM6 can you go back to the stock firmware of 2.1?
Can I keep the HTC sense UI (I only want the main menu dialer anyway)? I saw that thread saying Sense 2.2 is about 85% done? the Froyo rom yo usaw is the wildfire port and its in major alpha form right now. There is no fully operational Froyo sense rom for the hero yet
Somewhat Important:
Can I install the wifi tethering app on 2.2 Cyanogenmod? YES im using it right now
Does Sprint notice if you tether and cut you off? NO there is no way for them to see yo u have root and are using it
Do I have to root my phone? YES in order to go to CM6 or any custom rom you need to. ALong with wireless teething
Isn't giving root to potentially malicious apps a bad idea? Of course there is always a risk for anything. Thats why you nandroid before installing anything or before making setting changes.
Is giving root on a per-request basis? YES..superuser will pop up asking for request for any app that asks for request..you can allow or deny
Can I remove the stupid Sprint boot animation?YES, Cyanogenmod CM6 removes the sprint boot logo with e android cyanogen mod one.

And you can All you'd have to do is RUU
If all you want from Sense is the dialer, there is always Dialer One on the Market. I have been running more AOSP-based ROMs than I ever really ran Sense, so when I finally got bored with the stock dialer and gave it a shot, I didn't even notice it was supposed to replicate the Sense dialer, ha. It's a hell of a lot more customizable, and I think it's much "cleaner" looking overall (especially if you have it set to hide the green dial button in the contact list, and NOT have the keypad when the dialer is open by default, and taking up at least half the screen).
That Wildfire port is old. This is the current ongoing 2.2 Sense port, if you're into that sort of thing: http://forum.xda-developers.com/showthread.php?t=834840
Okay, that was exactly what I needed to know, thank you. After reviewing the various pages, are these the correct steps to get 2.2 Cyanogenmod up and running?
Root phone
Backup apps/SMS, etc.
Backup using nandroid

Flash Cyanogenmod
Restore app/SMS backups
Install GApps, Sprint Apps, Sense port (as needed)
hello the only question i have is about the froyo 2.2. i Installed CyanogenMod-6.1.0-RC1 on my hero 200 and its running great only problem i found that i have is i have no flash support on my browser. what should i download to get my browser back in running order as far as going to most of the sites i used to that had a flash media player embeded?

Yes, the Hero really can't install full Flash 10.1 because the default specs just won't handle Flash. Supposedly its possible with some overclocking and/or JIT enabled, but even then most ppl say it's not perfect.
We can install a Flash Lite plugin to browsers....try searching for that either on the market or through Google.

You can root with .7. I used Regaw's last time I did after an ruu to .7 build. There are great Gingerbread roms now. Aosp flavored like Jaybob's Rom which has the newest .35 kernel baked in; cm7 has begun using that kernel in their builds as well ( although it might not be the newest yet). You can download titanium backup to back up apps and data (sms too). Just follow the directions in the op of whatever Rom you are looking to install.
Sent from my HERO200 using XDA App
It worked! That was nice and painless, just don't have your Hero plugged into a USB hub with a dodgy cord like I did. I'm going to go and disable OTA updates as described in the old tutorial. Should I install Cyanogenmod or aosp? It looks like some of the Hero wiki links are pretty dated now, and the only aosp 2.3 link is to a 2.3 aosp labeled unstable and the thread mentioning that the dev quit working on it. I'd love a recommendation on how to get a stable 2.3 install running, I mostly want Exchange sync and tethering.
Id reccomend jaybob rom or kush I'd say jaybob since he still does update from time to time both r still awesome

This may be a noob question but I would like to modify/flash my phone but I have a question before I do. I have done a few searches to find an answer but came up with nothing so far.
I have been browsing the forums for different mods that you can do for the Samsung Captivate. Out of all the mods that I have seen (One Click Lag Fix, Root, Cyanogen, Leaked Froyo Build, GPS settings changes, Removal of AT&T bloatware, unlocking phone for other carriers, side loading enable, and various others), they can ALL be undone using the Odin3 One-Click Stock Rom process correct?
ttp://forum.xda-developers.com/showthread.php?t=731989
Hoever, each captivate has unique phone identification information such as IMEI, Device ID, Wi-Fi MAC Address, etc? Are there any mods that change the unique information for each specific phone? If so, how does Odin3 One-Click Stock ROM process correct that? When Odin3 reflashes to "Stock" ROM, I just want to know how that works if each phone has specific information.
Thanks in advance!
yes they can be undone with odin one click, however once you stray from stock it is most likeley that you wont be able to update to the official 2.2 from att.
personally im going to wait and update to official 2.2 from att then root and nandroid backup and the fun will begin because I will have a backup of the official update with my unique device id to fall back on. in my opinion this is the safest way to make sure I dont screww myself and not be able to update. once that is done it wont be long untill someone builds a decent rom from scratch plus like I stated before I will have a nandroid backup of the update for my phone if I try something and dont like it.
If you still feel compelled I havent gone to the leaked 2.2 but I did have verry good results with stock 2.1 and voodoo lagfix on anather captivate. the phone was verry fast with verry few side effects well woth it if you really cant wait.. But just remember once you stray from stock I believe the only way you will get to 2.2 will be through these forums.

anyway i got question about the topic - i had stock 2.1 (JF6), backuped it, tried some cognition 2.2 beta, then flashed with odin to stock and the restored my backuped jf6
did my IMEI, Device ID changed?
(wifi's mac address cannot be changed)
thanks in advance
I am speculating here.
I dont think it can change any hardware I.D info but software I.D is anather story it could possibly cause problems with the O.S interfaceing with other stuff like market.
someone with more knowledge please chime in
Theres a new app in the app store (as of a few days ago) that allows you to change your Android ID#. Called Android ID changer
Unfortunately, it won't figure out what your unique # is. If you install Cognition, you have the same ID# as everyone else.
I'm not sure about Odin - stock. My Odin 2.1 # is different than the Cognition one. Ends in 43b1. I'd be really interested to know if anyone else could check their Odin 2.1 eclair JF6 (all stock, not modified) android ID # and see if it ends the same as mine. If it's different, then that means you can always revert to JF6 to figure out your real #. If it's the same, then I guess that means for the time being your SOL for figuring that out for now.
You can always check it before making modifications....
Shadow; you are probably right, but at the end of the day software is all that matters...
Thanks for the responses. Judging from what I have been reading on the replies so far, nothing can bring me back to my original stock android 2.1 OS with all original software IDs my phone had even if I use the steps outlined in the

Just as long as you are running any of the stock eclair 2.1 without any mods all your unique id's wil display correctly, even if you have flashed to cog 2.2 or leaked 2.2 if and when you flash back to a truly stock eclair 2.1 the id's will return correct.
The android id changer app from the market will display the current android id your phone has when you open the app - it shows the current id just above the entry field where you can change your id. So download the app open it get you id write it down, save it in a safe place, then if you flash any rom the does not populate you unique id correctly you can reinstall the android id changer and enter your correct id manually.
Is [STOCK ROM] Odin3 One-Click Downloader and Drivers CAPTIVATE ONLY method a "truly stock eclair 2.1" as you mentioned in your post Davy? Also, are there any other IDs I should be aware of and take note before I flash/mod anything?
Thanks.

I believe odin 3 one click in that thread is a straight rom off a phone with samsung jf6 stock install - yes I'm fairly certain it is stock. There is another odin 3 one click for the leaked 2.2 which is obviously not stock.
If you download an app from the market named simply " ID " it still give you four of your phones id numbers for your info.
I'm pretty sure all your phones id numbers are either generated from hardware coded info or your google account - so as long as you gave properly coded software on your phone these wil always populate correct - even if you install something that messes these up of you remove the bad software replace it with good software it should then populate the id numbers correctly again.
Such as the android id in the leaked froyo that isn't being generated but simply being copied to every phone it is installed on - when you replace the froyo leak or any of the roms built off the leak with one of the stock samsung roms your phone will then generate the id correctly again.
No thread jack but i thought id ask in here.

maybe, maybe not. Some of the people who were rooted only (no mods) were able to update to the jh7 update. And from what I have heard mini kies has worked to update for everyone that flashed back to stock and tried to update that way - but this is all some what of a guess as we don't know exactly how att and/or samsung will role out froyo for the captivate.
You are all really funny. Your worried about getting an official OTA from AT&T so you won't mod your phones, lol. Your choice I guess but the last AT&T OTA bricked a lot of phones that had not even been rooted. The ROMS that you find on these forums are way better than any of the stock Samsung and AT&T put on them with their bloaty, buggy software. I won't do any OTA updates, I wait until the developers here fix them, remove the crap AT&T put's on them and speed them up. I give you guys credit though, staying stock sucks bad, it freaks me out to see that stock screen everytime I flash back to stock before flashing a new ROM to my phone. I only stayed stock for 2 weeks and never turned back, glad I did it too. I would've bought an I Phone 3g if I wanted to stay stock and not mod a phone. Go look around the forums and read the threads, don't just skim them or you won't learn anything. See what custom ROMS and kernels are cooking and what people are experiencing with them. We had the OTA rooted on here a few hours after the update was rolled out, you won't miss anything by not recieving it officailly from AT&T. Hell we already have some good Froyo ROMS and kernels. Keep waiting if you want but there's plenty of goodies here why wait?

Different strokes for different folks man, Its not like im using the tw3.0 and the blue bubble background lol ive customized stock 2.1 how i want it to look and its working PERFECT for ME, fast as hell, gps locks on quick etc. Flashing a rom is nice and all but the risk of bricking youre phone is high (theres always odin i know) and if stock is working for people then more power to them.
The way I look at it is, the phone belongs to you, do what you want with it or to it as you please.
but I do agree with one point above, I personally would not trust a samsung/att update to not mess up my phone. But that does not mean it won't work well for you or that you won't be happy with it that way.

IMEI can never change. I don't think your device ID can change buy your Android ID can change as you've been told by those before me. If it possible to change your WiFi MAC address, only I'm not sure how to do it. If you can do it in a full version of Linux, I don't see why it's not possible on our phones. Also, before you do any mods, make sure you backup a couple files onto your computer for safe keeping. The ones I'm talking about are in the /efs directory of your phone and relate to unlocking the phone for other networks. The second you go to mod your phone, these files will be erased and replaced with ones that are harder to get your unlock code out of.
I am new to Android and just got a Captivate. I understand its pretty glitchy with the Samsung software and am wondering about a couple of things:
1. I hear a lot about rooting. What does this actually do for me? Is this loading a new Rom? Or are those two seperate things?
2. Which is the best software Rom to load on it with the best performance and least glitches? Is getting stock 2.2 Froyo on it an option or does it have to have the TouchWiz interface?
3. Whats the easiest way to load it?
4. Can I save the stock Samsung ROM in case I need to return and replace my captivate (warranty)?
This will definitely get me started in the right direction. Thank you!

1. Rooting gives you superuser permissions. Read about it on this site.
2. Since you obviously didnt read the site I'd suggest loading Cognition. Beyond that I'd suggest any of the roms you can read about on the site.
3. If you go to cognition you can read about how to install with odin from his ponack website. Just click the link to download and Read his site.
4. If you get rooted and install clockworkmod's rom manager from the android marketplace I think you can do a nandroid backup as well as a rom backup. I am sure there is a thread in general about how to do that. Just go read it.
Will the cognition rom root my phone as well or is that a seperate thing I need to do? Should I first Root , do the Titanium Backup and then mess with the rom?
Also, once I have Cognitions rom installed, I wont be able to check for software update on the phone , correct? I will have to download future releases from his site?
Thanks! You are helping a ton. I just want to make sure I go about this right. Maybe I will start with just rooting and not mess with the ROM currently. What is the advantage to a different ROM?
What is the best way to root? Are there different roots or is rooting all the same, just different procedures. I saw this one and it sounded simple: One click Root/Unroot for Captivate
Once rooted and when Samsung releases 2.2 will I be able to download and keep my root or will I have to root again?
Oh, also how do I backup the original rom in case I need to return my captivate?
You can use ODIN one click here on xda to return to stock. First thing you need to do though is search captivate dev section on three button fix. Make sure you are able to get into download mode as this is essential before modding your phone

Hi there,
I have a Samsung Captivate with:
Firmware version 2.1-update1
Baseband version I896UXJI2
Kernel version 2.6.29 [email protected] #2
Build Number ECLAIR.UXJI2
This phone has been successfully rooted and unlocked using the method described on XDA developers http://forum.xda-developers.com/showthread.php?t=831569
Then, it has been lag-fixed(now works much faster)
I love the phone the way it is, unfortunately some applications crash. Most important of all, skype refuses to work on my Samsung Captivate - loads up, once I put in the user/pass - gives me a message that Skype has crashed and restarts skype. Some other apps crash on startup also, like Maverick for example.
According to the info on the net, I need 2.3 Android to run Skype.
I've read guides/stickies on this forum and others, but I am still unclear on the following:
1)Will I have to root/unlock the phone over again after updating Android
2)What is the difference between Froyo, Eclair and Gingerbread?
3)My GPS takes forever to lock onto satellites, even in open field. Does the update fix this problem?
4)I understand there are a bunch of custom ROMs. Some promise improved performance, etc.. If I want one of these, do I update to these kernels right away from my current 2.1 ROM or do I need to do an update?
Thank you so much in advance!
1. If you go to a custom rom, no, you shouldn't have to. Most roms will root you by default.
2. Eclair = Android 2.1. Froyo=Android 2.2. Gingerbread =2.3. Beyond that, it's mostly incremental improvements and features (You may have to do some of your own digging to find out what those are).
3. Maybe. Different rom/kernel/modem combinations affect GPS performance differently, and there are even GPS-specific tweaks that can be used. It will be a matter of trial and discovery to find out how it works for you.
4. If you're still on 2.1 and thinking of going to 2.3, I personally wouldn't do any other updates at this point. Go find a rom you want to flash to, and VERY carefully read its flashing instructions. 2.1 is a good starting point to jump to 2.3.
Post any more questions if you have them.
