[Captivate Q&A, Help & Troubleshooting] m37h:
My curiosity and adventurous spirit got the better of me :D

I'm a 1st time android user but have sone decent linux knowledge, so I kinda know what's behind the scenes after doing some reading.

So I decided to play around and and ended up spent my weekend having fun, an in the process bricking my lovely phone twice. Thanks to Odin I don't need to call Rogers to try getting a replacement :p I'm on AT&T 2.2 Cognition Beta now.

From my experiments, if you changed your phone to use AT&T version (I897), either 2.1 or 2.2, you can't go back to your Rogers stock ROM unless someone create an Odin like version.

The stock ROM provided in the I896 Wiki requires ROM Manager (which uses the ClockworkMod Recovery Image). Now the problem is the way the ROM loaded, I don't know the exact details, but to me it seems like Odin load the whole thing fresh (kinda like you re-install Windows) while ClockworkMod only try re-install (kinda like upgrade in Linux) which is a problem if you're going from one flavor to another, i.e. from I897 back to I896 (analogy probably like trying to change Debian to Ubuntu without a re-install).

I'm probably way off, please correct me if I'm wrong.

I can't post link yet, but search for "What's the relationship between Odin and Rom Manager" under Q&A in this forum.

Conclusion:

- we need someone to create an Odin like version for Rogers stock ROM

- be ready to brick your phone if you're trying to use I897 related stuffs on I896, they're not completely compatible (don't worry, it's not the end of the world, there are plenty of ways to get your phone back

- wait a couple weeks to get more stuffs compatible to I896 and avoid the headache I had ... well it's mostly fun, but I did have my moments of doubt :eek:

Hi welcome to the forum!

Since you have the phone and Linux background, would you mind looking into why the SIM unlock method used for ALL other Galaxy phone does not work on the Rogers version please?

I would love to look into it but I am still pending for HUP...

Thanks a lot in advance!

Just like to say that yes you can use the warranty in Canada I've already sent mine back and had it fixed. The only hassle is shipping is not covered and you need a US return mail address. I used a US mail forwarding service for mine.

Repost from eariler in the thread for those who need it.

NANDROID for I896 (Restore using clockwork recovery mod -- DO NOT FLASH AS A ZIP).

Unzip it on your SDCARD and restore the backup through the menu in clockworkmod.

http://dl.dropbox.com/u/10481943/Rogers_Stock_CWM_Backup.zip

If the link doesn't work yet, it's still uploading to dropbox's servers.

(PS. Same files as posted earlier, just a different name and rezipped because I had it sitting on the SDCard before reposting.)

Also contrary to whats said above you should be able to go back to 2.1 with a NANDROID restore unless something doesn't work right with CWM on the Galaxy -- I do it on my other android phones all the time. That's the whole point of backing up the NAND flash memory on the phone. Mostlikely the only thing it doesn't touch is the modem rom (but since my files use the rogers modem that shouldn't be an issue either).

If someone want to edit the build.prop to show the proper I896 version number, and repackage it with a different boot animation go ahead -- My friends still reporting back good things with his other than some FCs and the return of the GPS issue, but those are just bumps in the road at this point.
[Captivate Q&A, Help & Troubleshooting] opcow:
I'm not saying there's no way to make it work, but the only person who has had success restoring this still had Rogers firmware on the phone. Myself and at least 2 others have reported that it doesn't work. I personally tried it at least 4 times starting with different firmware versions on my phone, and although my phone is the AT&T version the others who reported failure were using Rogers phones flashed with AT&T firmware.

As further evidence that the firmware on the phone prior to restoring this nandroid backup has some effect on the outcome, I have repeatable different behavior depending on which firmware was on the phone when I booted into CWM and did the restore.

That's what I'm experiencing as well, I can't go back to Rogers after flashing to AT&T version(s) using Odin method.

Wow, lots of new developments since I last read this thread.

So I have successfully rooted and applied the RyanZA lagfix to my first ever android device thanks to this thread and It's contributors! The steps found here are pretty straight forward, though I had some hiccups in the rooting process like the "waiting for device" and the constant looping.

For those who are still not sure of how to do the process, here are the steps I took -- YMMV.

1. Download and install Samsung 32bit drivers here: http://dl.dropbox.com/u/8901364/SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe

2. Download and install SuperOneClick here: http://xdaforums.com/showthread.php?t=803682

***It wouldn't hurt to read over skim over the first post, especially the "Read Me" section ;)

***If SuperOneClick seems to be looping back and forth while trying to root, this post fixed that problem for me: http://xdaforums.com/showpost.php?p=8915657&postcount=358

***The rooting process may take several attempts! From what I have been reading, the "waiting for device" and looping is fairly common. Follow the directions outlined in the "Read Me" posted in the SuperOneClick thread, and read the above post by seanwalton to help you along the process. Be patient.

3. Once rooted (check to see If you have Superuser in your applications drawer) download RyanZA's lagfix in the market and install on your Captivate.

***When you first run RyanZA's lagfix, It may say It has not been granted root access, this Is probably because you do not have Busybox installed. Hit the "Problem?" button, and It will install Busybox. Also, remember to install EXT2 tools found in the app before applying the lagfix!

***After Busybox and EXT2 tools installed, I rebooted, ran a quadrant test (found in the market) and scored 835.

4. Run the lagfix and BAM! You now have a rooted, and super fast android device! I ran the quadrant test again and scored 2100+ :)

I hope my explanation will help those of you who aren't sure how to root and applied the lagfix. It's not all that hard, It just seems that way because there's so much info floating around this thread. Enjoy!
[Captivate Q&A, Help & Troubleshooting] sportyankz:
after rooting your device say you have problems with it (software or w.e) , rogers will not take it back im guessing. So is there a way to "un"-root it somehow to restore it back to its normal state.

I recently got mine from rogers and not sure if i should root it. Kinda scared to incase anything happes.

Please advise
[Captivate Q&A, Help & Troubleshooting] GTFO!:
Thanks for the steps, but is unrooting just as easy? and is it "safe" to root? I heard if you root it, app developers can have access to your personal info/passwords on the phone?
[Captivate Q&A, Help & Troubleshooting] integrasaurus:
No problems to report so far. Browsing and overall response is MUCH better. GPS locks on just as good as well.

Yes, there's an option in SuperOneClick to un-root, but I have not tried it.

Generally, rooting and lagfixes will not mess anything up. If you are worried that your phone might brick on you, or all these other things you have been reading, that usully only occures when you start flashin ROMs.

If you're happy with how your phone currently is, and have no desire to make it run even faster than it already is, then just leave it as it is :)
[Captivate Q&A, Help & Troubleshooting] integrasaurus:
I can't tell you whether or not it's 100% safe, but I don't think you should be worried too much about it to be honest with you. Make sure you download apps from somewhere reputable and not from hacking sites and such.
[Captivate Q&A, Help & Troubleshooting] GTFO!:
Ah okay, so all the apps on the android market are considered safe? and can I still access the droid market if I am rooted? are there any restrictions once I am rooted?

[Captivate Q&A, Help & Troubleshooting] PhrProfess:
Would someone please be so kind as to speak on how rooting and applying just the lag-fix has affected the performance of their battery?

Also, what else has rooting allowed people to accomplish with their phones?

Thanks

I'm wondering if rooting is worthwhile. I'm running stock, and not really noticing any significant lag.

Would rooting allow me to switch around the icons on my "shelf"?--or is there a way to do that without rooting?

ADW.Launcher or Launcher Pro from the market... Much better than touchwiz.
[Captivate Q&A, Help & Troubleshooting] ksimilie:
Im using an app the shuts off wifi, data, gpd, and brightness to low. and ill lose 5% an hour on moderate use. Moderate use is like 20 minutes of gaming, 3-5 minutes surfing the net ( i turn on wifi for that lol) and yea thats about it. But 5% an hour gives me 20 hours, so i can live with that.
[Captivate Q&A, Help & Troubleshooting] integrasaurus:
I have had my phone for 4 days now, and the battery life has been getting better everyday. Note that I am draining the battery as close to dead as possible, and charging it back up fully every single time.

I just rooted today, so I cannot comment on battery life after the root, but apparently battery life should improve.

If you want to switch around icons on your doc, look into LauncherPro, it's pretty nifty. Much better then stock IMO, and does not require root access.

Btw how can u get 576hrs of standby time on the phone as advertised? Could my phone be faulty?
[Captivate Q&A, Help & Troubleshooting] GTFO!:
Ahh, I only did the battery drain three times because someone said it isnt good to do it more than that.
[Captivate Q&A, Help & Troubleshooting] integrasaurus:
It's advertised standby time -- you might have to turn everything off in order to acheive that amount of standby time lol.

You have to remember it's a smartphone with 1ghz processor. Battery life will not be that great compared to dumbphones. That being said, if your phone lasts an entire day with moderate, be happy.

Do yourself a favour and not use those percentage battery stats, they just make you more aware of every single incriment, and make you worry about your battery more often.

We Need a SGH-I896 ODIN

We really need to get ODIN created for the Rogers Captivate. Does anyone know how to contact the creators of ODIN? If we don't start reaching out to the developers ourselves then we will never see a Rogers Captivate ODIN app created for us as the developers are focused on the SGH-I897 ROM's. I'm not sure if they actually realize that our ROM seems to be better (GPS works for us lol) so maybe if we contact them they will create!! I wish I knew how to do it. We should start putting the word out in the AT&T Captivate forums that our ROM's GPS is excellent and see if they can help us and themselves as well. What does everyone think?

[Captivate Q&A, Help & Troubleshooting] m37h:
If you read the last few pages, you're not alone. We can't go back currently. That error you're having is because CWM recovery mod is not compatible with 2.2, not sure if there's any work around. In any case we're stuck with 2.2, but I don't see the downside other than GPS is not as good as Rogers' stock.

If you want to load 2.2 Cognition, the simplest way for me was to use the Odin method, you need to be able to go to "download" mode on your phone. Dig around, it's pretty simple really.

SGH-I896 Firmware

Hey all

Attached is the Rogers Captivate SGH-I896 firmware. Firmware version I896UXJI2. I bought this from MoDaCo for a donation and it is the one loaded on all Rogers Captivates. I don't know how to install this so if someone knows please respond to this. Or if this will help to create a ROM then by all means please download. Hope it helps.

Used Odin and loaded successfully but upon reboot and seeing the at&t logo, it tells me it's not going to work and I was right. I got back the I896 logo as well as the Rogers splash screen but it sat there for a good while and just stopped loading. I could probably be doing something wrong or using the wrong tools to load it. Also, there's a dll included with the rom and I don't know if it's meant to be used somewhere. First time in this cellphone stuff so not really knowledgeable. I wonder if there's a way I can ran CWM in the recovery mode?

[Captivate Q&A, Help & Troubleshooting] hey_joe:
Yeeesss, I got back to Rogers stock using CWM to restore my backup. Here's what I did.

First flashed the image posted by seanwalton ( thanks very much ). It will not work though off the bat ( at least for me it did not work maybe because I was doing it wrong or using the wrong tools ).

Since it's already flashed with Rogers' I remember what opcow and another poster said where he successfully restored his Rogers' because he's using Rogers and not AT&T firmware. So used CWM to restore my backup rom from Rogers and presto back to Rogers. There's one downside I see right now though. The AT&T logo is still there :(

Hope somebody can package a Rogers rom for us canucks much like the cog where you just load it from the sdcard with CWM.

Thanks very much for all the help people.
