newbie..flashed to Cog 2.7, wifi stopped working, any good rom?

Hi, my first post..
so i read some and rooted my captivate, flashed it to Cognition 2.3b7 and since then my wifi stopped working...
I am guessing I can flash with another ROM ?
and don't have to go back to stock build??
if so which rom should I go with? I like the Gingerbread look and feel but open to try others...this phone is new and I don't have to worry about files/information yet.
thanks for your help

First, welcome to XDA, but...wrong section, this belongs in Q&A not development.
Mods please move.

You want to flash stock using odin

Don't try to flash another rom directly on top, you will compound the problem.
Have you tried reboot on your phone
If you are lost you can pm me

thanks mcord. so if I go back to stock do I have to root again?
also please let me know which rom to use to flash..I read Assonance 5.0 might be good?

You should have an update zip on your sd from rom manager/clockwork. Take this fille, and save it to your pc, our external sd. When you are on stock put it back on your internal sd, boot into recovery, reinstall packages twice, you will have clockwork recovery. Youcan flash roms from here without root.
I am not sure your problem was from cognition, maybe a bad flash. I am using assonance, so far so good but I have not been on it for long, axura is nice as well.
I would also suggest that you do a master clear after odin, make sure you are not keeping any troubled files. Make sure you backup anything you do not want erased to your oc or external sd
Remove sim and external sd before odin, master clear, or rom flash. Suggested not to flash roms with usb plugged in. always best to flash with full bat

Well, If you are going to flash trough CWM then no, you dont need to root again because you dont need to root to use CWM. Just make sure you keep the CWM update.zip on your sdcard boot into recovery and choose reinstall packages and you will boot into CWM.
And about the ROM. Well, you could try Cognition2.3b6, Perception8 or Assonance. I heard Cog has better battery life than Perc but Perc is faster, also the main diference is that Perc is based on i9000 ROM and Cog is based on Captivate ROM. I really dont know anything about Assonance escept that people say it's good.

If you are looking for another ROM, consider Assonance: http://forum.xda-developers.com/showthread.php?t=856877

Hi guys. First post so hope I don't look like an idiot!
Flashed Cognition v2.3b6 2 weeks ago but had to go back to stock 2.1 jh6 reason being while @ home I can connect to my protected wifi network with no problem but if I try to
use an open wifi network say at Denny's or an AT&T hotspot my wifi just loops and no hook up! {N/G} Have to switch back to 3G to get to on the net. After flash back to stock no wifi problems anywhere. Yesterday, 12/22/2010, flash to new Cognition v2.3b8. After flash went to Denny's and wifi N/G! Am I alone here or is anyone else having this problem? Flashed back to stock and today did Kies mini update to jh7, AOK! Went back to Denny's and had no problems connecting to wifi??????????????????

Reboot & Wifi "error" after 2 weeks of using any ROM

Hi all,
I've been unable to find a post about this for quite some time so I decided to make a threat about it.
I have a recurring problem with my captivate. Usually after about 2 weeks of using a ROM my phone will have 2 issues pop up simultaneously. They seem to always happen together. It seems to happen after my phone shuts off and will not turn back on until I battery pull. Once I do that I am presented with these two issues:
1.) When I try and toggle Wifi it attempts to then simply says "error" underneath it. I have found a few threads about this but no answers
2.) Upon installation OR restoration of any app with Titanium Backup my phone does a soft reboot (goes to spinning CM logo or for ICS goes to the multicolored squares flying around).
Edit: On the newest MIUI it now says "insufficient storage available" instead of rebooting when I try to install an app after the issues crop up, wifi "error" is still the same
I've had these same 2 issues occur with CM7 Stable, RC, and many nightlies, MIUI, and TeamHacksung's ICS build. I believe it may have happened with cognition too but am not positive.
I do not restore any data with TB. Before each flash I wipe system, cache, dalvik, and do factory reset and still this issue occurs without fail after about 2 weeks on any ROM and the only fix I have is to flash a new one.
Nandroid backups DO fix the problem. If anyone is willing to look through logs or something and see what was different I would be eternally grateful and certainly send you something through PayPal
Any help is greatly appreciated and I am willing to try anything at this point. Thanks!

Sorry for the double post,
Is there a better forum to post this in?

Nah this is the right place. That's a very strange problem you're having though, and I don't know what the exact solution is, if there even is one for this. The only thing I can suggest is going back to stock, and then reinstalling CM7 or whatever you want

Thanks,
Well happened again on newest MIUI. Gonna go back to stock and start over. I'll update the thread if it does or does not happen again.

Unfortunately after using Odin to go back to stock and rerooting/flashing it happened again on the most current build of MIUI. I'm currently at a loss for what to do. Has anyone heard of or seen anything like this?
Thanks in advance

Just curious, have you tried leaving it stock and seeing if it happens on a pure stock ROM? If so it could be a defect with the phone?
If you flash back to pure stock and the issue doesn't come back, maybe try a custom ROM that's closer to stock, not a CM or MIUI or ICS build. I haven't seen this issue, just trying to suggest some solutions.

I had this same problem with my fascinate. I flashed 1.10.21 MIUI follwed by glitch 13.1. This combination used to work, or so I thought. I flashed back to stock, 1.12.1 then a different package of glitch 13.1 and my wifi started working again. I know the captivates and fascinates are somewhat different, but try this out and see if it works.

I guess I could try that, I just like CM7/MIUI so much. Another thing that happens is many different applications start FCing after the problems all begin.
I tried to restore to a nandroid backup I had made before it happened this time and I received an MD5 mismatch which I believe happened last time I tried to restore...

New info:
I have not realized this before but it seems that I start getting a message that says, "Google Talk Authentication Failed", around the same time. Also FCs happen much more frequently. Is there anything I could be doing to cause this?

New Info
Just going to keep this updated with things I have tried in case anyone ever searches for this that has this issue:
Full format of SD card and odin back to stock did not prevent the issue from cropping up on the DarkKnight3 ROM with Icy Glitch. At this point I can only assume it is somehow hardware relatedl

I've used CM9 and now CM10, but no such a problem here. (maybe it's hardware related? :S)
If you really want to go back to stock than read THIS thread.

Thanks

Which ROM are you currently using? If it's cyanogenMOD than you should know that it doesn't have that feature at all.

im on slim..just want to know if when going back to ics if i do it like i flash any rom? (with recovry) or do i need to reflash threw odin?

I just did this to test something, lost everything including internal sd card. I believe it had to do with the partition differences between ics and jb. Had access to recovery but had to buy an external sd card as the phone wouldn't boot and was seen as an unknown device in xp so using odin was out of the question. Got an ics rom on the external sd and flashed via recovery but said something about the encryption process was interrupted and everything needed to be wiped. Hope this helps some but backup what you need before flashing.

First flash your mobile with 3-file stock gingerbread firmware using odin... then flash a custom rooted kernel using odin again... later you can install cm9 from recovery in cwm...

[Q] Custom ROMs dont work

Hello guys,
my friend has a Galaxy S Advanced GT-9070, and he had really bad stock ROM which came built in with the phone,
and i wanted to upgrade his ROM for MIUI or whatever..
So I flashed him CWM and tried some ROMs.
The ROMs flashed properly, but the phone got stuck on the boot logo each time I tried to turn it on.
I did wait a long time, about 2 hours, and I do have experience (successful one) with flashing ROMs on other phones.
Do you have any idea what the problem could be?
Any kind of help will be appreciated. :good: :good:

Give more details.
What CWM, what ROM'S do you flashed, did you wipe all with a clean flash?

You did factory reset? And bad stock rom was? JB or GB? You can't flash JB+ ROMs over GB.

Had the same problem for months due to faulty sd card. Try a different one.
