Here's a step-by-step for you...

On your PC open your web browser and log into XDA developers forum (you probably are already)

Go to oficial z4root thread and subscribe to it using "Thread Tools" drop down near the top

On your phone go to Settings->Applications->Unknown sources, make sure it's checked with green checkmark.

Go to Android Market on your phone and download official XDA-Developers app, it will allow you to browse this forum on your phone

Open the XDA-Developers app on your phone and login with your forum credentials (i.e. username and password)

At the top of the XDA app click on "Favorites" tab

Then click on "Topics" tab just bellow that, you should see all threads you have subscribed to

Click on z4root thread

Drag your finger down on the screen until you see page navigation menu at the very top (it says "Pages" and has arrows on both sides)

Click on the left most double arrow button to go to the first post (a.k.a. OP)

Scroll almost to the end of the first post and you should see an attachment there, looks like green android with "Download" button next to it.

Click the "Download" button, you should see a progress dialog and then two buttons: "Open" and "OK"

Click "Open" button and you will be offered to install the z4root app.

Once the app is installed open it and click "Root" button, it should work from the first try, but if it doesn't don't worry, simply restart your phone in try again.

If you don't want to use XDA app to download z4root, you can download it to your PC and send it to your phone via email, bluetooth or just copy it over USB to internal SD card, though I don't see why you wouldn't want an XDA app since you're already here on the forum.

Exactly. Nandroid backups up the rom, so your apps and settings are restored to what it was when you first backed it up. That backup is only compatible with the same firmware that your running at that moment.

Hi,

Can anyone point me out to guide on how to install Perception or Cognition on the Rogers Captivate. I don't really know anything about Roms and Kernels I just want it to work, GPS included lol. I'm having trouble finding a guide which would show me how to do everything easily and comprehensively.
[Captivate Q&A, Help & Troubleshooting] KonArtist:
No you would not be able to(from what i read on the forums, started yesterday lol).

I'm looking forward to loading Froyo but got to wait til someone makes a proper root for it.
[Captivate Q&A, Help & Troubleshooting] shawn122:
lol...I have been reading on the forums about the phone but have just recently started posting. Someone over at HowardForums mentionned he could get into revovery mode..so if thats the case...wouldn't you be able to load Cognition 2.1.7? (not any Froyo stuff)
[Captivate Q&A, Help & Troubleshooting] HH007:
Its like the blind leading the blind

lol...

As my title says, its like the blind leading the blind.

I tried going into the 'Recovery Mode' and yes, it DOES work. Just take the battery, sim and SD card out, and put the battery back in. THEN, hold down the Volume Up, Down, and Power key simultaneously. When you do that, it loads into the Recovery Mode.

But, to MY understanding, unless you root the phone you can't run other ROMS (like Froyo or Cyano), you can't run Lagfix, and from what I understand, you can't run apps such as Snesoid, or PSXoid. I really wanted to play my old SNES games on this phone. Unless, I am mistaken about this?

You should be able to use odin to install cognition. Then you would have a rooted phone and be able to install clockwork recovery
[Captivate Q&A, Help & Troubleshooting] shawn122:
You are correct. Google is my friend! LOL

You need root for custom ROMS.

Now..the Voodoo Lag Fix for Eclair doesn't need root. Can we install it?

Or do you need to root it first?
[Captivate Q&A, Help & Troubleshooting] shawn122:
Hmm...if this is the case..thats great news :)

[Captivate Q&A, Help & Troubleshooting] bnevets27:
I know this is basicly an impossible question to answer at this time, but how likely is it that we will not be able to root the rogers captive?

I have one on hold for me till rogers "fixes their system." No one has been able to get a phone on HUP so far.

I'm just worried I'm going to miss out on all great ROMS and such things that are easily done on the at&t version.

Also, how much modification is going to need to be done to the existing roms/tools? Is it just a matter of changing the version from i897 to i896?
[Captivate Q&A, Help & Troubleshooting] HH007:
Its hard to say -- most of the development occurs because the mods HAVE the phone. And not many people HAVE the Rogers phone. Once they HAVE it, they can start work on it.

And as you can see, this will mainly be bottle necked by how quick/smart the canadian developers of these roms are.
[Captivate Q&A, Help & Troubleshooting] wmwilker:
I was just looking at the timeline and Designgears posted the JI6 Froyo rom on October 1st and around the 20th the Voodoo lagfix was posted.

So give it some time and you should have it all. :D
[Captivate Q&A, Help & Troubleshooting] bnevets27:
Yeah I guess we just have to sit tight. I think we are all a little anxious because of the months of delays we have had so wait so far, and so few of us are able to get the phone. I'll try to help once I'm able to walk out of a store with one.
[Captivate Q&A, Help & Troubleshooting] emuneee:
Disclaimer: I am not sure if this works. But there is a root process for the Verizon Fascinate (w/ Eclair) that worked on the leaked Captivate Froyo build. Some brave souls should try it (at your own risk).

Again, not sure if this works for the SGH-i896, just throwing out some ideas.
[Captivate Q&A, Help & Troubleshooting] rajendra82:
Has any one tried adding i896 model string to the one click root zip file we have. If not can someone try putting this update.zip (which was modified as I described) in their /sdcard folder, booting into recovery and trying to apply it. Usually the newer GSM Galaxy S model have only needed this modification to the file to root.

Obviously I can't try it without owning the device, but it should do no harm if it fails to apply.
[Captivate Q&A, Help & Troubleshooting] HH007:
Just a small update for those who might care

Hey all,

I have just had some time playing with my ROGERS Captivate, and here are a few things I noticed:

1. On my phone, there is NO rogers logo ANYWHERE. I know this is a minor point, but after all the headache this company has caused, it makes me at least FEEL good to know that there is no 'ROGERS' logo at the top, bottom, or on the back

2. Recovery mode does work

3. I do not think one will need to install a SideLauncher. The ability to install non market apps is NOT disabled. I have not tried installing anything YET, but that's a positive sign I think

4. Mobile AP is ENABLED. I don't know how this is possible, since I thought only 2.2 has this feature, but its there, and it works. I turned on the Mobile AP, and I was able to surf the net using my Captivate connection only. I got download speeds of approx 4 Mbps using Speedtest.net

5. Very few bloatware apps

6. It is missing the Android keyboard. This peeves me. They have the Samsung keyboard, and the Swype, but no Android keyboard. How or why this is missing I don't know. I was looking forward to just voice inputting all my txts, so I guess I'll have to figure out a way to load the Android keyboard onto this.

7. Browsing works well, but for some reason, I can't pinch to zoom...

Again, I am a noob, so I apologize if this is all old information to the rest of the people on the boards.

Check for HSUPA?

Can someone please install the SpeedTest.Net application and check to see what kind of upload speed you get with a strong signal?
[Captivate Q&A, Help & Troubleshooting] TheMeich:
I've had mine since Saturday and have been playing around with it since.

Pretty much agree with everything said.

Was REALLY surprised at the limited bloatware. There's 2 shopping apps. Don't know why theres 2, but whatever. There's an app for modifying rogers account info (which i actually use and find useful) and then the standard touchwiz stuff.

You can sideload apps without needing to root or install any special apps or software. As well nothing seems to be blocked from the Market like I've heard on ATT.

Mobile AP is fun as hell.

I've also been getting speeds on the speedtest.net app of 3000+kb/s Though I've only been getting 400kb/s upload. My phone says 3g at the top when I'm not on wifi, but when i activate the app it does switch to H with up/down arrows. I've run it 5 times and it's always a little bit above or below the 3000/400 mark with about a 180ping on average. Edit: While standing outside I can get 3500kb/s down 400 still up and 105ping.

Pinch to zoom works fine, a lot of pages are auto optimized for mobile and those don't use pinch to zoom, but regular sites pinch works great.

Probably won't get voice to text on the samsung keyboard until 2.2 comes out =/

Rooting this thing will still be worthwhile, but it seems we don't need it as badly as the US versions. I don't mind waiting a few extra days for someone to make a root for this rogers version. Still want superuser for full back ups and for wavesecure. Can't leave out launcher pro either.

I guess the long wait was quasi worth it.
[Captivate Q&A, Help & Troubleshooting] Red John:
Yeah... so no HSUPA. So glad I didn't wait for this and picked up a Bell Vibrant instead.
[Captivate Q&A, Help & Troubleshooting] wholewheat:
no, i don't think so. i flashed the cognition rom onto the captivate and lost the gps function after that. then i changed the settings after coming across that post and everything works properly.

Hey guys.. Just before I try Root + RyanZA Lagfix. I want to make sure. Does everything still work with no problems after this is done?

I Have alot of apps on my phone and alot of pictures in my Gallery and I am starting to notice lagging issues, especially when I load the Gallery app that came with the phone. It hangs there sometimes and freezes if I don't wait.. Never had this problem with my Galaxy S i9000..

So i'm really tempted to Root + Install RyanZA Lagfix. But I want to make sure 90% of you people with i896 Rogers Cappy's are running perfectly with no problems + GPS still working..

Please let me know! Thanks!

Works fine, but i still get gallery freezes. Once i did a factory reset i havent gotten them but i have no apps or anything. Not sure whts causing it and no ones been able to find out. Im just waiting to move up to 2.2 or 2.3 and not have to worry about gallery problems.
[Captivate Q&A, Help & Troubleshooting] fluidd:

[Captivate Q&A, Help & Troubleshooting] ksimilie:
Yea. Actually it was even worst then that. Usually it will freeze I will restart and it will work until it freezes again. Well two days ago it froze, I restarted and after rogers logo it went black, and wouldn't load. Left it like that overnight but nothing. Had to enter recovery for the first time and do a reset. No more freezes though.

Seems easy enough I just lost my N1 :(

I need at least Froyo, can not go without Chrome to Phone, Apps to SD card, better battery life/Flash 10.1 be nice too; and by the time Samsung releases Froyo I think this community will be running Gingerbread.

Samsung says the official release is what now early 2011!!!!! What do the mean early 2011 April? and it has been already delayed they can delay again.

I have a few questions and I hate to read all the pages to find the answers, "lazy"

I understand the AT&T Captivate is SGH-i897 does this mean no ROMs for us?

Do I need to unlock my Phone or is just Rooting it good enough?

Convert Files to .tar

Hey guys I found these I896 Files from XDA somewhere don't ask can't remember where. But these files were from a RESTORE_I896.zip containing Heimdall files and Rogers I896 files: boot.bin, sbl.bin, factory.rfs, cache.rfs, modem.bin, zimage.rfs etc. Anyways, I want these files converted over to a TAR file so that I can flash them using ODIN. Is there a program to combine these files into one tar file able to be flash by Odin? I can upload the files if you guys don't already have them?

Unless you have the 3 button recovery option its not recommended. It's also very early and not a daily rom. It's still a dev/tester version no reason to flash it yet. It is moving very fast toward a usuable rom but they still need time.
[Captivate Q&A, Help & Troubleshooting] CDNChaoZ:
Quick question guys. I'm a newbie to the Android world (loving it by the way).

I'm been fairly happy with my Captivate so far, but I'm the type who usually wants things running to their full potential.

Will the upcoming Froyo update from Rogers supposed to fix the lag problem?

If I root and lagfix today (z4root and ryanza?) and Rogers pushes the Froyo update next week (ha!), will I have trouble updating?

Thanks guys, learning a lot, but still a ways to go for me yet.
[Captivate Q&A, Help & Troubleshooting] sshvetsov:
Highly unlikely. The lag is mostly caused by poor implementation on Samsung's part. They used rfs filesystem which is terrible at caching multiple writes. Most lag fixes create an ext2 or ext4 partition for caching.

From what i've come to understand, yes. You will probably have to undo the lag fix and unroot first.

Keep in mind z4root doesn't seem to work on 2.2.1 update, if that's what Rogers is going to push, you won't be able to root with z4root afterwards, unless they find and implement another exploit.

Has anyone tried using TV out feature on their Rogers Captivate?

In case you're wondering what I'm talking about, open "Settings->Sound and display->TV out" and enable TV out checkmark.

Wondering what others are using for their modem on Rogers Captivate I896.

Here's what I have

Firmware version

2.2

Baseband version

I897UCJI6

Kernel version

2.6.32.9

jataek.lee@sep-11 #1

Build number

Cognition.v2.3b8

even thou the device is originally I896, after flashing it's marked now as I897. My experience with this build is 4-5 min of GPS connect and battery drain at literally 1% every 3-4 mins...Still want to stick to 2.2

I tried a couple of modems this morning, all seemed to show more battery juice than before they were installed and the 3g down (web surfing) was blazzing fast, Just that the phone side of things there was no sound, could n't heard anything on a phone call... Had to flash the phone back to Cogn 2.3b8 to recover... Here's what I tried, 1) Telus TLJL3, 2) -I9000UGJK4 and 3) I9000UGJL2, neither worked on the phone side...

I forgot to mention in my post, but I tried that on both of my cables, still no go. I think the position of the ground on pinout could make a big difference. I found this in one of the forums, if my cables have ground on pin 2 instead of 1, that would explain why I'm getting noisy picture on all three cables (yellow, red, white), since it's the one pin shared by all of them.
