Please help if possible: Captivate Locked, but in a reboot loop - Android Q&A, Help & Troubleshooting

Dear readers, i just got a Samsung Captivate Galaxy S I9000, here is the problem.
1) It is locked to Rogers Wireless, because my friend tested it by inserting his Rogers SIM card into it and it works normally like a phone.
Here is where it gets interesting:
2) When i insert another foreign SIM card such as FIDO cell carrier. The phone boots into the lock screen and it says Media Scanning...and then it proceeds to the booting up screen again.
From my lack of skills in Android software, i am really stuck. But from the powers of observation, it seems the phone was flashed and is currently running a custom ROM on it from Serendipity VII.
The phone runs perfectly, without a sim card, but that's like holind a tablet without a phone line...=(
I have not done anything to it but have been reading forums after forums and it seems that mine is a rare case maybe? Please help for those who are Captivate users or are experts. What should i do?
I would really really appreciate if someone could guide me in a step by step detailed manner to fix the Captivate loop. I am at the moment looking for sources and contacts to help me remove the network lock on the phone.
Until then, if anyone has any good ideas, workable ones and hopeful ones, i would appreciate that very much please =)
Here are some details on the phone's systems.
-Firmware version 2.3.3
-Model Number:I897 ????(Why does the boot screen show I9000?,custom Rom?)
-Build number: Serendipity VII Build 2
Please help, any advice, guidance and solutions are greatly appreciated.
-Jolinaiko

First I would like to say that if yours is a Rogers' Captivate then the model number is I896. Secondly the phone has 2 boot screens and a boot animation before you get into the phone. The first one is called upon by the primary bootloader and can be changed with some work. The second one which is probably the one showing the I9000 model number for you is called upon by the kernel and thus is only changeable by decompiling the kernel and replacing it.
As for your problem, not really sure why your SIM would cause your phone to reboot unless there's something wrong with it. Have you tried other non-Rogers SIM cards to see if they make your phone reboot?

Thank you for your response. I have tried other sim cards except rogers. It seems fhat non rogers sim catds do not work for the device. Any solutions or suggestions?

I do have the exact same problem with my i9001, when using any SIM, it shows the network provider in the lock screen, I get no signal and after 3 seconds it just reboots and is is a rebooting loop,
When I take out the SIM card, the phone operates normally

[Q] Atrix 4g WiFi not working

Hey guys,
i have the atrix 4g on which i used a simunlock code, so that i coudl put in my sim card from a european carrier, that works great, but the thing is the WiFi stopped working, it just went into a scanning/connecting loop and than it disconnects.
So i factory restored it and figuered out that s soon as i put in a working sim card (one that has cellular reception), the WiFi starts to behave like that and to get it to work i have to factory restore again without a sim card or with a nonworking sim card.
So i tried the motorola support and they said ye hardware issue, send in the phone, my problem however is im in europe right now and i cant really send or get the phone to motorola USA and they totally refuse to send it to an address outside of the US. However im 100% sure its a software issue (both things work for itself, and the thing that even removing the sim card doesnt restore the wifi funcionality makes me think there is some software issue).
So please guys if anyone has an idea how i could fix that i would be really greatful. Btw i tried some of the apps from the market to "fix" wifi (fxr, wififix etc). Fxr said it fixed the wifi bit it still wouldnt connect, the other apps just had the same issue as the stock wireless manager.
Thanks for your time
Did.you use software to unlock it or just a code?

I have the exact same problem.
My phone is unlocked and can make calls, but WiFi disconnects me almost immediately. The phone also thinks my prepaid sim has H+ connectivity.
When I go back to my AT&T SIM, I have to do a reboot or 2 to get it cleared up, and then WiFi works again.
oh, i see that, i guess its some sort of ATT measure to block nonATT SIM cards, eventho the phone gets simunlock code. But the funny thing is there are a lot of people for whom it all works (like the guys in the unlock thread, using it in canada without a hitch), so im really wondering if this is not just a software glitch (i hope it is and gets fixed witht he 2.3 update..), otherwise my only hope are the devs here to crack wide open the bootloader and put some custom roms on it =/ really a great phone, but all this ATT software crap makes it feel like its an Iphone ...
But uhm still, anyone has any ideas how to try to fix this problem before the updates? =/

i also have a friend in saudi arabia who got the unlock code and the wifi is working fine.
only 2 people reported this so far. i guess it could be a hardware problem ? because the other user beside you have this problem even without sim installed " or that what i understood from him "
you can check the other thread too. maybe someone could post something usefull.
hmm i see, where did you find that thread, i was sort of searching for ages and didnt find any issues like that =/
Ye i mean i have this problem without a sim aswell if i dont factory restore the phone, after i do that without a sim card however the WiFi works great...
so i am kind of reluctant to believe it being a hardware issue due to this, sort of software specific issue (at least i think if it would be hardware related, the wifi would start working as soon as i go to airplane mode/take out the sim and a factory reset wouldnt be necessary), or do you think that my theory is rather flawed in thinking that?
and ye the problem is im in europe now and as the reps at motorola support told me, i would have to send the phone to the US for warranty and they would only send it back to an address within the US =/ i will try my luck with the german and uk support site, to see if they could do something for me.
thanks for your time guys tho
hey guys what do you think if i would use this code:
* 2767 * 3855 #
Think before you give this code. This code is used for formatting the original manufacturer. This will delete all files and settings, including internal memory storage. This will also reinstall the phone’s firmware.
To restore it to manufacturer (will it request an unlock code again after that?) cuz i have 2 codes to unlock but the first one worked, so maybe if i woudl try it with the second one than?
I just unlock my atrix with the code from cellunlock, works great and wifi is fine as well. Would like to know where u get the code, and how it turns out if u try reset to default using the combo. Pls update. Ths

I'm having the same issue of not being able to connect to WiFi.
I bought the phone in Las Vegas with an AT&T - pay as you go (no contract).
I bought an unlock code from SwiftUnlocks, and used my Rogers SIM, which appeared to work. I then rooted the phone.
Using the Rogers network, I've been unable to use any sort of data. Phone calls and texts work fine. Then I noticed that my WiFi was not working properly. It would try to obtain an IP address, but couldn't connect. After several reboots, I got the phone to connect to WiFi for a few minutes.
I just did a factory reset, now I'm unable to connect to any network or WiFi to login with MotorBlur, so I can't really use the phone now.
I'm quite frustrated and not sure what else I can do.
Update - after putting the original AT&T SIM card in, and rebooting several times, the WIFI started working again.
I'm still unable to get Data working over the Rogers network in Canada.

i am getting my phone in few hours, then i am going to order from cellunlock a code and wait for 2 days to get the lock. unless someone has a spare code he can pm me i would be thankful.
the code is IMEI specific, cant give oyujust spare codes
secondly, to get wifi to work you have to remove your sim card, put in the att or a nonworking sim card and do factory reset, than wifi will work. and you can load all the stuff via wifi, and than just put in your working sim and use the phone as a phone +3g data (the 3g data works great for me to be honest)
oh i got my code from swiftunlock but i dont think that matters, they all get it from teh same provider im pretty sure.
and if anyone si wondering t he sbf update did NOT fix my wifi problem. i ahve tried several wifi fix programs and neither worked aswell, the fxr wifi did some stuff that the phone now sees the networks but still cant connect.
this is to update everyone that i got the phone. had an issue about the screen doing lots of flickering. contacted amazon and sent it back.
in the whole process so far i lost around 60$ between importing and exporting the phone. all in all. i will stick with my iphone 4 for now. its a good phone.
but i cant take this sadness all over again if i imported another phone with an issue with it as well. i am too OCD for my own good.
so true what you say, tho im coming form a nokia 6220 classic, a bit older than the iphone 4
Hey GUYS...

[FAQ:Request for Sticky] Atrix 4G - Wifi Problem on Unlocked Phones

Please if you found solution reply here, but read at least first post before.
1. Does AT&T SIM reactivate WiFi, after other operator SIM used? - Yes (in my case), but you may need to reboot (soft) 2-3 times.
2. Does Motorola Update 1.57 solve the WiFi problem? - NOT IT DOES NOT.
3. Why part of unlocked phones have WiFi problem and others not? - Open question, as it is NOT a hardware failure, it is somehow related to unlocking process.
4. Is there any solution at all? - Honorable member crnkoj is developing the solution in this thread
IMHO WiFi related issue currently deserves sticky. Also it would be perfect to have one stop FAQ for WiFi related issues.
Im using an unlocked atrix n the wifi is working fine...
You in the lucky group. Mine is unlocked and none of the many potential solutions get me on wifi (short of tossing a broken sim in, which is a pain...)

1. Apparently people who have one, reported it reactivates wifi after a few reboots, otherwise you have to put in a broken sim and do a factory restore to get it to work
2. It does NOT (not the leaked 1.5.2, not the leaked 1.2.6 and not the prerelase 1.5.7)
3. i think it has something to do with a config file or an app that blocks it (altho im leaning toward a config file that gets from the carrier some info and not really blocks but more like a bug disables wifi, because of some conflict)
4. you can use your phone with sim card and 3g/4g data, while preinstalling everything before on wifi, or just use it a a small wifi only "tablet". I am unfortunately not that good with android/linux to figure it out on my own (i sort of got the phone into a boot loop 3 times now, trying to delete apps/ change config files in the /system dir). One of the forum/irc users is nice and tries helping me , but he doesnt have the phone himself so, hard thing ...
5. Hopefully the released source codes will help, doing a semi custom rom without the att bloatware, which could probably fix the issue.
What about the new update that was just released does that fix the problem?
It seems up to now there is no solution for wifi problem. Several reboots doesn't work for me. Please respond if someone was able to succeed.
BMW, maybe read the 2nd point of my above post, no update fixes it.

I thought the new update started with a 4 but now I figured it out sorry.
It was big buzz week ago on broken wifi on unlocked AT&T phones. Now I can't find even the thread on that. Did you people find solution?
I have upgraded to 1.57 and it is definitely not a solution.
I tried hard reset with non-working card and wifi on hardware level works perfect. As soon as I've put working SIM in, it stopped and even reversing to non-working sim doesn't help. hard resetting every time is not a solution.
Still waiting for final solution.
I unlocked my Atrix in Australia. I shall walk you though my steps to see if you can pick out anything specific. I was very worried about the WiFi issue so i took many precautions.
I bought the code from Cellunlock.net - using the android50 code to bring it to $20
in the meantime I used an old, inactive SIM in the phone and on boot I would just hit dismiss on the network unlock screen and run the phone on WiFi on my home wireless. (WPA2 key)
When my unlock code arrived (2 days) I went to the wireless settings, DELETED my wireless network from being saved.
TURNED OFF WiFi entirely
Turned phone off properly and replaced the SIM card with my active Vodafone AU SIM
on the network unlock screen, I used the first code out of the two they provided and it was accepted
went back and re-added my wifi network, and doneeee all is working well.. hope this helps someone somewhere.
Thanks a lot DarkRyoushii
Problem is that I received my Atrix already unlocked. I contacted Cellunlock.net if it is possible to unlock it second time, but they responded it is impossible.
What gives me hope, Motorola has to sell originally unlocked phones and their ROM should be free of this AT&T crap. So using that ROM supposedly will help.
I have an AT&T Atrix and the unlock code didn't adversely affect my Wifi. I've actually never had an Android that locked onto Wifi as well as my Atrix. It's tight as hell. Never, ever drops!!
I don't see the correlation between the two but maybe there is some weird quirk. Not denying anyone though. I just wonder what the heck Motorola did to the framework to cause that to happen. Weird.. hope it gets patched up too.
I hope this gets fixed soon. I have an atrix with the sim unlocked. I cant connect to wifi, and I cant get passed the motoblur to set debugging and root the phone. This is very frustrating. I'm in qatar so I dont have a att sim, nor do I have a broken sim either. I guess I have a $600 dollar paperweight.
mine is perfect

Don't put any sim in it at all then turn it on. You should be able to connect to wifi that way and get past the setup.
I don't have an atrix yet but I heard that this works. Goodluck.

Your wifi wont be fixed after you put a sim in but it should get you past the motoblur sign up.

Guys, if you have 3g (or in fact any) data available on your sim its not a problem. When the motoblur setup tips up, click the settings hard button (the one to the left) choose "configure apn" (or something similar), put in the data you get from your carrier and bam, you should be able to finish the setup.
Wargame1 I bought several sims at eBay and is planning to check with them. As soon as they work, I'll let you know and even send you one from Baghdad.
Wifi problem is not solved yet. When Motorola is going to start selling originally unlocked versions? Their rom should help.

just try it with mobile data man, youll be able to activate motoblur...
and erm, you probably wont be able to install the unlocked rom on the att atrix, sicne you cant change the att/bell roms on the phones either .... maybe just a /system reinstall, like the Gingerblur/Gladiatrix mods

[Q] Can't Use Network On Atrix 4G (Requires 'Network Unlock PIN')

I swapped my SIM card for a T-Mobile one and my phone asked for a 'Network Unlock PIN' even after I put the AT&T one back on it. I called AT&T and they gave me the code so I can use the phone on any network and it did not work at all. My phone is in a unusable state. I even got the code from a 3rd party and they gave me exactly the same number AT&T did. Any help would be deeply appreciated.
Theres a guide here which involves flashing a different radio. Search out, doesnt work 100% but it might to you.

Have you solved the problem yet? I have the same problem I even sent in the phone twice to Motorola for repair and that didn't work.
Sorry I don't check this website often. I went to a Device Support center and they replaced it for me. All I did was get rid of the "Unlocked" message and messed it up so it won't boot up. But I forgot to check if flashing the baseband and radio.
All basebands can be found here (Latest should be the best):
http://www.TecKnoZ.com/Android/Atrix/Baseband/ATT/
Tools to flash this files can be found here:
http://www.TecKnoZ.com/Android/Atrix/Tools.zip
As for the radio, just Google Atrix 4G radio. I will upload it to TecKnoZ later on
Let me know what happens
Don't see how flashing a radio to your phone is going to fix this.
What is the exact error message you are getting?
Edit: Try 5555 or 6666 and see if that does anything?

"No Sim" Error on AT&T Galaxy Note

All of sudden, my phone does not detect the SIM card anymore. I inserted another good SIM card, and get the same error. I tried to press the SIM card to ensure good contact, but not working. No problem with other function. I inspected the SIM card slot and it appears perfect. The phone has never been dropped or having liquid damage.
I did the factory reset, but could not get rid of the error. Unfortunately I just travelled to oversea...
AT&T agreed to replace the phone, but I will not have any phone on the road.
I am willing to try anything. Does not seem to be software related, but...
Anyone know how to fix the problem?
Thanks.
Hey. There us a thread about this just search for it... don't think they found a solution
Did this happen while your sim was still in the phone or after a removal and replace?

[Q] "Can't connect right now. Try again later." or equivalent in stock, CM9 and CM10
Hi folks! Needing some help, please.
I've googled my problem a lot but couldn't find any working solution. Below is the detailed history.
I have recently bought a Samsung Galaxy S3 GT-i9300, cut my previous SIM, and used it for about four weeks with no problems. During this time, I rooted my phone, backed up the stock ROM, installed CM9 and afterwards CM10.
About a week ago, while using CM10, I switched off airplane mode after about nine hours and the signal power meter was empty. All the services related to my carrier (SMS, 3G, calls) were inoperative. I rebooted the phone, tried removing and reinserting the SIM, with no success.
I tried flashing the previous backups, also with no success, but noticed that while using the stock rom, the signal meter was full. This prompted me to access "Settings > Wireless (...) > More... > Mobile Networks > Network Operators", where to my surprise all the available carriers were listed. I did the same check in the rural area of my town, where I know my carrier does not work, and the cellphone correctly detected only the other three carriers.
These symptoms led me to believe that my cut sim could be the problem. I got a microsim from my carrier, but the problem persisted.
After this, I assumed the problem was software related, googled it and found some recommendations:
Complete wipe and backup restoration: this was not successful with stock, CM9 and CM10.
Complete wipe and stock ROM re-installation with Odin: also not successful.
Modem flashing with Odin: also not successful.
Firmware flashing with KIES: I put the cellphone in download mode and made the firmware recovery procedure from KIES. Also not successful.
Restoration of efs folder and IMEI related issues: I did not have backup of this folder, but the symptoms related to the problem in the posts I found always included the absence of IMEI. When I type *#06# in my phone, I can correctly see my IMEI, so I discarded this possibility. My carrier also informed me that my IMEI is not blacklisted.
I thought of getting a new microsim to rule out any SIM related issues, but still haven't done it.
Information regarding my phone:
Phone model: GT-i9300
Baseband version: I9300UBLG2
Firmware vesion when on stock (from KIES): PDA:LJ1 / PHONE:LI2 / CSC:LJ2 (ZTO)
Could someone please help me? I still have not tried the EFS folder troubleshooting, but the procedures I found were related to problems that did not show the same symptoms as mine. Do anyone have any suggestion? Please tell me if any more information is needed.
Thanks!
Why not just get a micro Sim to begin with....they don't cost anything and it saves a whole lot of hassle. My guess is the sim reader is damaged....IF and WHEN you decide to get a new micro sim, if it doesn't work then that could be the only cause and the service centre your only option. Seriously dude, next time to save yourself hassle....go an get a micro sim from your carrier, I wouldn't even think about hacking away at an old sim because I can't be bothered to walk to a Vodafone shop.

I have just come back from the carrier store, where I got a new SIM, and the issue persists. I also double-checked any IMEI blocking or problems with my services, and everything is ok.
Coincidentally, a Samsung consultant was around. He checked my phone and talked to Samsung tech support describing the issue.
They do not think it is related to the cutting of the SIM card for two reasons, the first being the ability to locate the carriers, the second being the fact that a visual inspection of the slot and the scratch marks on the SIM card do not indicate a broken or bent contact.
Obviously, he recommended that I send my phone to an authorized Samsung service center for maintenance.
I am still inclined to think it is a software related issue. I will, of course, send my phone to Samsung if it is case, but in the meantime I would like to try new procedures to bring back my phone's ability to connect to my carrier.
Suggestions?
Thanks in advance!
An additional information:
I tried checking my sim through some apps, to confirm there is no damage in the contacts. GalaxSim Unlock is able to detect my sim and correctly show my phone status as unlocked.
Any suggestions on tests?

Hi!
I bought S939(not completely new), which from what I understand is not a device that's created for the European market. In order to make it function, I believe that the device was rooted\modified. Now, I can perfectly use it to go on the internet, make photos ecc, but when I put my SIM , I'm unable to "catch" the network of my provider. A message "Can't connect right now. Try again later." appears. I can save numbers on the SIM, for example, but unable to register on the network.
Also on the main screen, I can see writter "Invalid IMEI".
Thanks!
