[Q] Perception build 9.5 and phone service

Hi, I'm currently running Perception build 9.5 on my captivate and it seems that my phone randomly loses service. I've never had that problem at home or in the city with Eclair and my family doesn't seem to have this issue either so I can only assume that the perception has to do something with it.
When I'm in this state, I try to turn on airplane mode so that I could turn it back off but I can't do that either.
What can I do to fix this phone service error? I miss calls and don't receive texts until I restart my phone!

Airplane mode doesn't work? That's weird, perception is one of those ROM's that has a pretty huge userbase so problems that come out of the woodwork usually get answered pretty fast. I would try flashing back to stock and master clearing, and see if that makes a difference.
If it doesn't, I would try flashing over other modems(modem.bin), to see if you can find one that will give you service. You can do that via ODIN or a prepackaged CWM .zip flashable. Pretty sure Perception 95 comes with JL3. If reflashing/masterclear doesn't work, try some other ones!

Well actually what ends up happening is that it freezes and then as soon as I restart the phone, it restarts as airplane mode. It's pretty annoying. I will try first restoring 2.1 and then whos knows what

So I tried to restore my old samsung 2.1 onto my phone but it is stuck at the "DesignGears" Logo at the very beginning. I've tried restarting using the power and volume buttons and restoring again using the same image that I used but to no avail. I've tried to press the factory restore button on clockwork but didn't work either. I can't even get it to load all the way! What can i do?

Not knowing the details of exactly how you flashed your rom, it's hard to say exactly what could be wrong. From the sounds of it, though, something got corrupted in the process.
I had something similar happen the one time I tried to upgrade without taking everything back to JF6. My suggestion is to back up what you can, start over from scratch, and reinstall 9.5.
When you start that process, drop back to JF6 with Odin, then do a Master Clear, and only then install Perception 9.5. Going that route, you shouldn't have any problems.
Ad for your failed 2.1 restore, I'm guessing that you're talking about a nandroid backup? If so, it doesn't back up the kernel or the modem. You'll have to use some other means to get those reinstalled. I'd again suggest using the Odin 1-click to drop the original rom on the phone, then performing the nandroid restore from there.

thanks so much guys!
I did that as you said and used Odin 1-click to restore my phone and have installed 9.5. Hopefully this will conclude the thread. I will let you guys know by tomorrow. I really appreciate both comments and wish you guys happy holidays!

Actually, yea. Nothing has changed. My phone still loses signal every hour or so probably because of the switches. I wonder if we can contact a dev about somethin like this?

Most of the Devs that use i9000 or Vibrant ROMs for their base are aware of the problem. At this point seems there is nothing we can do though. I keep flashing things like Perception and Phoenix thinking one day it will work, but it never does. The only stable build for signal are Captivate based, ie, stock or Cognition.

Only has service on custom ROMs

just a quick question... for some odd reason everytime i go back to stock, i never get any service... it will keep going from the ghostbusters signal thing to some bars then back to the ghostbusters thing... cant make calls or use data... and it keeps saying updating time and date when it does grab a bar or two... however on any custom rom everything works perfectly... ive tried relentlessly to figure out why and try to fix it... did the airplane mode, changed modems countless times, and nothing fixes it except using a custom rom... so i gave up and just told myself u didnt buy it to not mod, but wtf is going on lol...
any ideas?

Check which version of Odin youre using, and try another. The one in the AIO toolbox http://forum.xda-developers.com/showthread.php?t=944418 should work perfectly fine.

come to think of it, i have been using the same one over and over... downloading AIO now... if it dont work ill just have an excuse to get a new phone 6mo from now, sell it, and get something better...

just to follow up, a different version of odin, and still the phone is unusable when on stock... can't use the network for anything... oh well... guess im guaranteed a replacement whenever i feel like it...

[Q] Signal issues with custom ROMS & kernels

Ok im at my end with this, whenever I have a custom ROM on my captivate I constantly lose signal and have to reboot my phone to try to get it back, sometimes twice. The main time it does it is anytime I charge it, whenever i wake up the next morning no signal. Then sometimes it will show I have signal but It wont allow me to do anything (calls, text, or internet) So far the only ROM that I havent had any problems with is Cognition. And I have also tried numerous modems, ROM, and kernel combos, but still no luck.

Many threads have discussed this. "random signal loss on i9000 roms"
No solution or definite cause has been found afaik. Some think it has to do with the phone itself and a refurb is your only remedy other than sticking with captivate based kernels/modems/roms.

So I should only flash 897 ROMS, we need a list of which is which

The list is short. Nothing atm besides cognition which is actually a rogers rom...might be one more.

well cognition for me than. Till someone finds a fix.

Cog. 3.04 has been a great rom, I have been sticking with it and FB2 kernel, other setups make my phone do wonky things, bluetooth voice call is only issue. Be great if that gets fixed but no biggie.

Just out of curiosity what is the build # of your phone? If you look on the white label on the back of your phone (remove the battery) you should see it there.
Be interesting to see if it was a specific build or not.

Firefly is also a rogers 2.2 have you factory reset at all? Bad hardware?

Andromeda doesn't have that issue either.

Firefly and Andromeda both had the issue on my phone, which I hated cause I really wanted the themed Andromeda.

rev 0.4, just cant trust anything at&t

Seems to affect rev 1007 and a few others. I did a warranty exchange and got another 1007 that works with everything. Running CM7 now.

UCKB2, 1106, Updated Froyo?

Just went down to at&t and exchanged my 1007 captivate for a 1106. The firmware on it is UCKB2 instead of UCKB1. So far the gps is horrible but I haven't had much time with it. Its still stock no root. I'll get back with you guys later. I have to go for now.

That sucks, also the reason why I don't exchange my 1007. The GPS works, it ain't great but it works.

GPS didn't work on my old one either so I figured I'd take the chance.
What I find interesting is the updated froyo build.

Hi, Wolf how did you get a 1106? Did you set up an exchange over the phone or did you go into a at&t device center? I just setup an exchange of my 1007 that I got on launch day in hopes of a better GPS. I thought I would try it out before my 1 year warranty was up. I was hoping to get the newest hardware rev. but your experience sounds bad.

I went to the local AT&T store and tried to explain to them the GPS issues I was having. They ended up getting hung up on AT&T Navigator trying to tell me to use that to get my GPS to work. Eventually they set me up to call the AT&T warranty department. Then the Warranty Department told me that kept thinking it was a software issue and wouldn't honor the warrant and told me to call Samsung. Called Samsung and they told me to call AT&T, then I had the store manager talk to Samsung themselves and eventually it got worked out that I was able to to an in-store trade out. And I got the 1106.

So if anyone wants me to create a back up / pull the firmware from my phone I'm going to need assistance, as I've never done that before. The KB2 Rom maybe more stable on another device.
Edit 1: Also, on this build the colors seem to be a little off. Maybe a little warmer than normal.
Edit 2: Just rooted and made a backup so I can start flashing this thing. If anyone wants the FW the offer still stands until Monday at 6PM eastern time. After that I probably won't have time to pull it for a while.

^ Dang, wish I could help, but I don't have the know-how.
Sure hope someone offers up. I really would like to test that KB2 modem out.

unknown sources enabled perhaps ?

That's something you should have tested before you left the store.
I just returned my 1007 via the phone and received a 1012. That phone's GPS didn't work either so I went to the repair center (40 minutes away) and exchanged it again.
I made them confirm the GPS would lock in under 10 seconds on the first phone they brought out, another 1012. It did not so I asked if they had any newer builds...the guy brought out a 1102 and it grabs a lock and holds it.
The 1102 also had the UCKB2 kernal which has the signed bootloaded which must be cracked before customer roms will work. Annoying, but there are easy workaround to it posted here already.

UCKB1 official Froyo build is horrible in many aspects. UCKB2 is probably just some bug fixes. I'd skip all AT&T Froyo build to the UCKF1 Gingerbread ROM. So far it is a much better 'official' ROM than any official Froyo ROM. If the rumor is correct, GB ROM will be released in the middle of July, I'd bet this UCKF1 is the final build.

Interesting. I exchanged mine last week. GPS didn't work, search button pressed itself sometimes etc. Got one with great GPS, but didn't notice when dim the screen was yellow. Had to go back and got an 1102. Didn't check version but right now I'm on cog 5 beta 3 and got there with no problems.

I just went and exchanged my phone again. This time I got a 1106 with KB2 and perfect GPS. I got 10/0 (visible/in-use) satellites inside the AT&T store. As soon as I went outside I got 10/10. Inside this old gov't building I'm seeing 6/0 in the center of the room but close to the window I get 7/5. Never out of all my Captivates, this being my fourth, have I seen such good GPS.
I also made it a point to show the difference in GPS ability compared to my old phone, my new one, and the display units to the store manager so he couldn't try to BS me.

I got my 1105, and it had UCKB2 on it as well. The GPS was terrible. Call quality was great, though. So far, I've been using the KC1 modem, and GPS lock is fast and stable, but call quality suffers at two bars and less.
I never knew that the GPS issues could be related to hardware problems, but it makes sense. I can put my wife's BB Torch next to my Cappy and she has -65dBm and mine has -95dBm. I've burned through about all the modems thinking it was software related and now I'm wondering if my phone has other issues. I can see a dB or two difference simply due to different antenna configurations, but a 30dBm difference is huge (the scale is logarithmic).

Just thought that I would add to this thread. I just got home from the Warranty Center with two replacement Captivates both with UCKB2 on them. Haven't had much time to fool around with anything yet though to confirm GPS or bug fixes.

GPS is the best ever on my new 1012 UCKB2
I had a 1007 before and the GPS with various fixes was "OK" - much better than my wife's 1007 with the same config. However, I swapped it out yesterday and got a 1012 with UCKB2 and the GPS works perfectly. I actually wondered if I should stick with stock (a horrible thought) since I didn't want to screw up good GPS and then not be able to get KB2 back. It took quite a few tries to root it - SuperOneclick 1.95 worked after failures with One-click, SuperOneClick V2 beta and 1.7.
I will flash GB regardless - Continuum Platinum when it hits GA. However, IF by some chance I want to revert, flashing a 2.2 firmware ROM and then restoring a nandroid backup should get everything but the kernel and modem. Is there any way to get those back? I haven't tried yet but apparently KIES only installs KB1 from what I read.

I honestly don't understand why you didn't just one-click back to JF6 and install CWM and flash from there. You over complicated it I saw your post in the old JI6 2.2 thread. None of that was needed.

When I told at&t about the gps issues on my cappy and you know what he told me? He said most smart phones even his htc aria has gps behavior which is normal. I told him about that the gps tend to jump around time to time and doesn't stay at one location. I don't believe what he says and can't issue an warranty exchange before the time is up.

I just exchanged a 1007 Captivate that was having all sorts of issues (gps, phantom search button click, random shutdown) via warranty. I received a 1008 batch phone.
First impressions were that GPS wasn't great, but phone signal was fantastic. Overall ran smooth. After figuring out how to install alternate recovery 3e, I backed up with CWM and one-click flashed to JF6 to do some test restores.
Once in eclair I decided to try restoring back to UCKB2. Whoops! Suddenly I didn't have button recovery or download modes, and was stuck in a boot loop (with recovery 2e). Not cool -- built a jig and flashed Andromeda3.
Now that I'm running voodoo lagfix ext4 again, I'm noticing some high CPU usage from kswapd0 that drains the battery. I don't think this was occurring in UCKB2 froyo and would like to flash back to do some comparison.
Is there some trick to restoring the UCKB2 ROM or should I just try again? (obviously after disabling the lagfix.) Not looking forward to another soft brick if I run into difficulty...

[Q] Having problems with Android 2.3.4 on Samsung Captivate

Im having some problems with my phone. I recently rooted my phone with the rom found in this thread.
http://forum.xda-developers.com/showthread.php?t=1232703
Since i have put it in, I am having a problem with a few functions. The first problem is that i cannot accept phone calls. when i receive a call, a black screen comes up, i get the first half second of my ring tone, then my home screen comes up, it shows that i lose signal completely, then my time/date updates. anyone have any idea how i can fix this?
the other problem is that i cannot see txt messages by clicking on the message itself. normally a black screen would come up with white txt displaying the message, i no longer have that. Thats not as annoying as the answering though haha.
I was probably going to switch back to froyo but it would be nice to get this working
In order to get this rom, i rooted with fugu first, then installed the rom. Thanks for the help everyone

Not knowing too much about this ROM, I would 1st try going back to stock/master clear, and try to reflash it again. If you haven't flashed may ROM's I might suggest a ROM that has some serious traffic to it, most of the bugs will get either worked out or identified really quickly.
I don't mean any disrespect to the dev of this ROM at all, but like I said, if you're fairly new to flashing, go with a ROM that has some time in the trenches
It sounds like a bad flash to me so, I'd reflash to stock and try again

Well, if you want a Froyo ROM, I would ALWAYS suggest Phoenix:

If you want to use Gingerbread, Mosaic VI:

They are both VERY good ROM's. Phoenix isn't being dev'd too much anymore, but honestly, it doesn't need it. Most deving is going into GB now. If you want GB, give the instruction in Mosaic a good read, they are really clear. Just make sure you understand what you're doing before you do it

No prob! The install for GB is a little more complicated than Froyo. But, most important is read totally before you flash. It'll make your life so less stressful
Also double check what you use to get back to stock. Personally I use Odin 1 Click, but you need to be sure you don't have a specific build number(I dont know which ones they are) Or you could soft brick and need a Jig to get back into Download mode
