The Samsung Captivate Guide: FROYO 2.2

This guide is for if you are on Android 2.1 and want to get 2.2. If you are fine with 2.1 use this guide. If you already have Cognition you can use this just skip the install cognition step. If you are on a different version of 2.2 you need to do an ODIN reset (second to last page of guide)
UPDATED 10/11
This is a guide that is similar to the other guide however it is for DesignGears Cognition ROM.
Drivers
Rooting

No problem! If your still thinking about upgrading I would say its worth it. DesignGear(s?) makes great ROMS. However it does erase your userdata (although for something the files still remain on the SD card (like music). In addition in you want the official Froyo release you will have to use ODIN to flash back.

So, I just want to clear things up for myself.
Right now, I am running Eugene's ROM.
I will flash back to stock JF6
I can download the Cog 2.2 BETA6.zip file. Put it on my SD card and flash it using Clockwork.
If I want to flash back to JF6, I can use Odin to that.
Does all that seem right or is there more to it?
I did read the guide and it is excellent. I am just hesistant here, so just wanted some confirmation.
Thank you for your awesome work.

You use ODIN to get back to stock 2.1. Then follow the guide to the beginning. A summary of the steps to get cognition is:
Flash to 2.1 Eclar
Root the 2.1
Flash the zip file with clockwork

And skip JH7 altogether? Cognition contains the JH7 "fixes"?

That is what my understanding. I did this with an un modded captivate. I am pretty sure that was JH6. If you have a PC you can always just use his ODIN flash to install it and that is that. But I have a Mac so I made my guide Mac friendly.

pretty decent guide

Great Guide, Works Awesome!
Samsung Captivate
AT&T
Install went smooth as can be. I had to install the drivers, as told by the guide, but I think you may have missed a step?
Under "Installing Froyo --> Prepare" you may want to add a note that the phone has to be in Mass Storage mode to transfer the ZIP. Not sure if this is always true, but I did have to do that on my own (it was not showing the phone when it was sitting in debugging mode.)
I will be sending you a $5 donation. Really wish I could send more, but simply cannot. I am hoping others are doing the same, as this guide is awesome...
I did have one question about the 2.2 update. I heard somewhere that this would fix the GPS issue, however, I am experiencing the same issues with connectivity. Does anybody know if Samsung/AT&T plan on fixing this?
Again, thanks!

I think asking for a donation for copy & pasting postings into a PDF is cheap.
But I suppose you can't blame a guy for trying to skim some money off what should be going to the actual cooks.

If you look @ the date on the OP (Opening Post) then you'll see where your issue is.
This is an older thread. So the file no longer available.
Although I do commend you for ACTUALLY LOOKING for a tutorial thread and not opening a new topic.
The steps will all still work though. You can get the most recent version of Cognition (3.04 i think) in the link in my Sig
Happy Flashing!

thanks marzo, i found it. i just finished flashing and now im waiting for it to boot up with FROYO!

Not a problem... And it really is a Rearity that a person actually searches for answers around here.
Better to *BUMP* an old thread then open YET another.
Be careful though.. This is a very addictive habbit that your forming!

Can you update the guide for theh persons with the update to froyo 2.2 from AT&T.
Thanks.

Thank You!!
Thank you very much for this it was just what I was searching for!

thanx
thanks for this

[Q] Losing apps after phone reboots itself

Hey guys, THIS IS URGENT!
Ok, here's my problem. Over the past week i have been forced to reinstall my ROM/ROM'S several times. My Infuse will at times shut itself down and i will have to restart my phone. after i restart my phone i notice that all of the apps that i have on the phone that i have gotten from the marketplace will be grayed out and really not on my phone at all. this is getting really frustrating and if i had the money i would be visiting my AT&T store to get a windows phone. I love android and want to stay with it but i am getting pissed.
Do I need to ODIN back to stock or what? The phone will run for about a day and then it will just do what i described above. If I have to ODIN to stock then could someone please tell me how to do it because i have not had to deal with that yet. I would like to be running Zeus on my phone but that is when this whole ordeal started.
If someone could please help me with this i would greatly appreciate it. I really hope that someone has had this same problem. Any help would be awesome!
Thanks,
Bassman

running on Zeus?

no running on dlevrom now...was running zeus and caty

what app were u running when it rebooted or crashed?

well i have a feeling that the way you worded that last post that i may fave effed this up myself.....heres how it went....i was on dlev first, then i flashed zeus, zeus did the missing apps, then i said screw this and went to caty, caty did it, and now back on dlev and it is losing apps....i know it's a crazy vicious circle but please tell me that i didnt do this myself and that it is just a fluke...

I have notice that crash mostly on zeus. sometimes it is triggered by tibu backups or different launcher or different setting of TW launcher with special animations etc.
This effect probably carried over from flashing other roms over zeus without proper factory reset or wipes.
go to my post on the q/a rom; use jordan's method of flashing the rom you want.
edit: here ya go
http://forum.xda-developers.com/showthread.php?t=1318160

i looked at the post that you gave me. is the method done by ODIN or heimdall? i am getting ready to bootcamp my mac so that i can try his method. after i do that method will i be able to run zeus again?

his method is with odin.
(if you are familiar with heimdall, you can take the package apart and use heimdall).
on the last part, flash Zeus ROM

OK, I will give that a shot. Correct me if I am wrong but I have been reading about ODIN and a lot of the stuff that I have seen says that it is not safe for your phone. Is that the case? i would rather just take it back to stock and leave it there if i have a high risk of bricking my phone. Also I would like to thank you for helping me with this issue.

you're welcome.
SOFT bricking the infuse is pretty common. Easy to restore. According to Adam Outler, a bad bootloader flash is possible to HARD brick it.
I think if you're interested in using ROMs other than stock (what comes with the phone), learning how to use odin or heimdall is a must.
These tools will be need to restore your phone to it's original state.
There are some risks, but if used correcly, most are minimal.
I would venture to guess the devs and flashaholics odin their device more times than you can imagine.
It's a matter of comfort level.
In reality, I think the stock froyo or one of the GB leak stock is just fine.
I had a "funny post" in the q/a section you should read.

again thanks for all of your help. you definitely gave me a lot of insight and knowledge that i needed to know that i probably wouldn't have gotten anywhere else. i managed to get caty running. i tried to flash zeus and it bootlooped the samsung screen. so i just decided to go with caty. dlev just wasnt cutting it for me. you have been a huge help and i will definitely recommend this thread to other people who have had this problem.

If you did get caty running again,
Before you do a whole lot, boot into cwm recovery.
Factory reset. Then wipe cache. Then goto advance. Wipe dalvik. Fix permission. Then reboot.
This should give you a relative clean slate.
Caty is also a very nice infuse base ROM. You're not really missing out on much. Just enjoy the phone. Leave the frequent flash to the flashaholics.

I did do all of that and the ROM seems to be running flawlessly. Thanks for your help man.

[Q] NS 4G Please Help!!!

Ok, so this is my first post. Been lurking for a while and doing a lot of learning. First rooted my NS 4G about a month ago. No problems at all. Well today, I was gonna flash CM9 rom but researched it a little first. I read where it said factory wipe and format. So thats what I did but I think I did a little something to much. All I can do is get into bootloader and the recovery. I have nothing on my SD cardexcept root.zip, to flash and I can't put anything on it cause it won't connect to the computer. Someone please tell me how to get this fixed. I'm gonna try the odin route and see if that does anything. I've searched and that seems to be the way to go. Wish me luck on that and someone who is more experienced knows a better solution, please tell. Just please don't tell me I'm screwed.

type fastboot flash recovery twrp-crespo-2.0.0RC0.img in cmd, in the correct folder.
Download that from this page: http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/
Once you flashed, go to recovery and this will get you into team win recovery project. From there choose mount and mount your sd card. Copy your rom into your sd card and than unmount. Go back and choose install and install your rom. If your rom required google apps, flash that too. Once your done reboot your system and bobs your uncle.

Thanks for the reply. I actually went the odin route, which I was then able to go back to completely stck and start over again. Glad I got it figured and to be honest, I probably jumped the gun in asking for help, but man I got worried when I couldnt do anything with it. Keep up all the great work everyone. About a month and a half ago, I never knew what rooting was. Now I can't wait for new updates on roms and kernels, to come out.

Need help to get my Infuse from GB to ICS then JB

I was wondering if someone could detail to me a sure-fire way to make the jump from GB to ICS. I've tried twice now and both times I got stuck booting into a blue CWM without being able to load a ROM at that point. I was able to boot Aroma but after trying to recover from there I got stuck at the Galaxy S screen. Yes I followed the instructions very carefully. Is there a way to do this via Odin or Heimdall?
Any help would be tremendously appreciated.

Stock GB with CWM > CM 9 flash twice first from red recovery and then again from blue > then JB.
Do a full wipe before and after all the flash.
I know u said u tried this way buy it did not worked for u just give it a try from scratch one more time.

Thanks rkkaranrk. The one thing I didn't do in your instructions was a wipe before and after each flash. Instead I wiped once before I began. Could this be the problem? Is this a common problem? I've seen some mention the same issue in the Dark Knight ROM thread that said they have the same issue but wasn't sure this has to do with the ROM or the migration from GB to ICS in general.

It could be any thing which cause bootloop so its always better to wipe, I always do anand never faced any bootloops Just give it try.

I'm going to give it a go today too. I've had a hard time convincing myself to leave Aeon though. It's been a rock solid / stable ROM..............

it does sound as if you missed a step. OP states you wll get stuck at Galaxy S screen.
you then pull battery and reflash again along wth the wipes.
i did wipes in recovery, then on second flash (in Aroma) did the full wipe version. install went exactly as described.
loving 99.9% of the Paranoid Android ICS. may want to take that for a test drive for a bit first beings they can be similar from what i know (which isnt much) from flasing one of first versions of JB
thanx for all efforts in development, biting my lip on flashing JB.

Thanks for all the replies so far.
@captemo: I followed the instructions in the Dark Knight thread exactly but maybe those instructions need to be updated because they never mentioned multiple wipes. There is no mention of getting stuck @ Galaxy S screen either but that isn't what happened at first. It kept bootlooping into blue CWM. It was only after that I tried to recover with Aroma that I got stuck, probably not the the wisest move on my part however.
I will try the Paranoid ICS build next since it sounds like you have had success with it and it looks like a good one. Just so I am clear on doing this can you list the steps you took to load this ROM? I noticed there are two variants, one with and one without the Aroma installer.
Thanks in advance!

The Aroma installer is nice but in my opinion, based on my experience and reports from others it is too problematic on the Infuse. Would really suggest not using versions with it, at least not on your first flash.

WOW, somebody waiting for MY advice??? are you sure you havent been sipping on grandpa's cough syrup?
Pony i'm sure has more experience than myself and is merely expressing experiences that others and maybe he himself have had. truth is every phone is different and will react different.
i do like the Aroma myself. allows you to install some apps automatically.
i did nothing special than follow OP slowly and carefully to the T. doing this, i have never had problems flashing anything.
if i do anything special it is carefully choosing what i wish to flash. when lookin for new ROM, i go to the last page and start reading backwards. that shows me the most recent problems and issues people may be having. if its a problem i cant handle, i dont flash.
i am not taking away from developers here because they are ALL amazing and i wish i could do some of these things. as for the Dark Knight rom, i download, but never flashed. i just didnt think the development was progressing enough for me.
thats just me.
good luck hope you like Paranoid Android. i like the tablet mode, though print can be small for old eyes like mine just changed the font to something BOLD.

The reason I wanted your advice was because you had successfully made the jump from GB to ICS. The Paranoid thread assumes you are starting from ICS so there are no instructions to go from GB to ICS even thought the ICS ROMs are still there.

anybody on ICS or JB as made that jump, obviously with sucess. since Paranoids development has jumped to JB there are a couple of small differences in install (GAPPS for ex.) the first 80 pages still deal with the ICS developments of the ROM.
even though the OP has changed to address install of JB, if you go past the first couple of pages and all the congrats of the new ROM, you will get to where any of your questions will be answered. Scott and team are very attentive and if you read read read, questions and concerns are all addressed.
if then you are happy with ROM and are dying to try JB, i think page 80 is where JB discussion begins.

The GB to ICS process should be the same for any rom. You can use cm9 or uniyumaporn to get to ics and then flash jb.
First, be aware once you are in ICS, your recovery will be filled with rainbows due to the lack of GB bootloaders (I'm assuming you don't have those).
1) wipe data, cache, dalvik (format /system is optional)
2) flash ics rom
3) reboot (Not "reboot into recovery")
4) you should hang at kernel splash (galaxy s screen).. remove battery and use 3 finger combo to boot into recovery.
5) wipe again and flash
Sent from my sweet & buttery Infuse

I did this process two days ago. I went from factory att GB to ICS following the instructions for uniporn. Once I had uniporn fully booted and running I then rebooted back into CWM and followed the instructions in the cm10 thread.
The only thing to watch for is in the uni instructions. It still says to flash gapps. You don't have to do that now because they are included in build 40.
How did you update to GB by the way? That will tell us if you have GB or froyo boot loaders

Hi Goneeuro,
I just saw your post but I did exactly what you did. Basically I read the instructions of a bunch of ROMS and decided to follow uniporns steps and it worked just fine including the gapps installation. Seems to be working fine still but I wonder if its a matter of time if I see issues.
I don't recall how I went to GB, its been so long ago but I don't have the rainbow CWM. Probably because I loaded them during a recovery.
Anyway all is good now. Big THANKS to all of you.

[Q] Infuse 4G stuck in recovery

Hey everyone,
I have a rooted Infuse that I've gotten stuck in recovery mode and I'm looking for some help! I have flashed several different ROMs over the last year but made a mistake last week by trying to take a short cut... Ya I know, noobie move. I had installed a rom and set up my phone but forgot to instal BLNTouchwake (it was compatible with the ROM) so I booted into recover any tried to install BLN without factory reseting and doing everything all over again. It messed up my phone a bit but I was able to flash a ROM onto it again and it worked until today. I tried to flash Carbon Rom 1.7 and it will no longer load a ROM. I am getting error status 0 and can't successfully flash a ROM anymore. I read a little bit about error 0 and that it's caused by a script error but that's starting to go beyond my technical knowledge and I have no idea how to correct that.
If someone could please give me some steps to try to get my phone up and running again that would be awesome!
Thanks,
Wardo
