Help: UltraSn0w "No service" on iphone 3GS, iOS 5.0.1, BB 6.15.00 (please help!)
Hi everyone! :)
I know you guys get this a lot, and I apologize for this long post, but I really need your guys help.
My sis recently got herself a iPhone 4s and would like to give her old 3GS to my mom. So they told me to try and unlock it and here's what happened.
Iphone 3GS specs:
- -Model: MC136LL
-Original BB: 05.16.05
-Build on 2010, 3rd week of January
-Sim cards used: 3, all are AT&T, including one that came with the phone
Day 1: Jailbreak with redsn0w 0.9.10b5, updated to ipad BB 6.15.00, install UltraSn0w 1.2.5 and reboot.
Disable all necessary settings like 3G, location services, cellular data, insert sim card and status comes out to no service
Then install this SAM module, followed their instructions, manually select carrier and viola, I got service! :D
But after a few hours, phone says no service. :(
Uninstall/reinstall UltraSnow, just update BB, revert phone back to stock IPSW and repeated the steps from before and no success.
Managed to downgrade the iOS from 5.0.1 to 4.1, Jailbreak with redsn0w 0.9.10 (no BB update), disable necessary settings, reboot
and insert sim card. Status gets stuck on "searching..." After that, installed ultraSnow 1.2.5, reboot, status comes out to no service.
Uninstall UltraSn0w 1.2.5 and it goes back to searching. Reinstall UltraSn0w 1.2.5 and it's no service.
So far it's "searching..." without ultrasn0w 1.2.5 and "no service" with UltraSn0w 1.2.5 :woz:
Btw, I found this commcenterclassic patch which is to fix this "no service", so I applied that manually (not officially supported for iOS 4.1) to give it
a shot and still no service.
Ran Sn0wbreeze v2.9.1, downloaded a clean ipsw of iOS 5.0.1 (from link provided within Sn0wbreeze). Then cooked a custom ipsw via Sn0wbreeze v2.9.1 with
the IPSW I've just downloaded. In Sn0wbreeze, I've only selected "hackivate and install ipad based band", and nothing else.
This time instead of using redSn0w to update my custom IPSW, I've ran iREB, enter DFU mode and update to custom IPSW from itunes.
After that, I ran Ultrasn0w 1.2.5, reboot, turned off 3G, etc, and insert sim card...no service.:( :(
Uninstall UltraSn0w 1.2.5 and manually download UltraSn0w 1.2.4 and installed it via iFunBox, then reboot iphone.
Insert sim card and WTH, I got service! :eek: But signal wasn't stable, bars keeps on fluctuating, and after a hour, it's back to no service. :\
Then I've manually ran the commcenterclassic patch via ifunbox and use ifile to change the attributes according to what that site says. reboot, remove/reinstert
sim card and service comes back for a few minutes before it goes out.
This time I've ran the patch automatically via Cydia, reboot and again the same thing. service for a minutes, and... no service.
So after a week, I've been doing a combination of things trying to get this working like running PurpleSn0w, jailbreak with limera1n,re-updated BB, turn on/off air plane mode and try as many methods I found on the web which I haven't tried before. And so far even went to look for paid version of unlock software (most of them are scams) and got desperate, by taping my jailbreak/unlock iphone 2G together with that 3GS, hoping Apple itself will do its magic, sadly it never worked. :P:(
I've tried everything, I researched so far with both my personal and my mom's sim card and so far it's hasn't been a success.
During the time I have service, I was able to make and receive calls with both sim cards.
My mom's sim card works on my unlock iphone 2G and also works on her semi-working regular Samsung cellphone.
I wasn't able to use the original sim card because it was deactivated by AT&T when my sis went to get her new phone.
I even tried that original sim card with my unlock iphone 2G, but it just shows no service.
The only difference I've notice with the original and the other 2 is, the original has a smaller contact footprint (3 rows) than the other two which
takes up more space with 4 rows of contacts. Does that make a difference even though, I don't see any contact markings on the 4th row of contacts with both my personal and my ma's sim cards?
I also went to various unlock places and they can't seem to unlock it either, one of them even said the sim reader on that iphone 3GS is broken?!
Currently I'm at this position where I've restore back that same custom IPSW I created with Sn0wBreeze v2.9.1
Disable required settings, install UltraSn0w 1.2.5 with patch applied and it's still no service.
Now did I do something wrong, missed a step or what?
If anyone could please list the proper order, I will greatly appreciate it.
edit: I was able to jailbreak/unlock the iphone 2G and it's been working great ever since.
Before I ran this jailbreak, I did try out the both my personal and my mom's AT&T sim card on this
iphone 3GS and it didn't work.
