Signal drop outs after installing Blackra1n on 3GS with ATT

I continue to have no problems after uninstalling Blacksn0w. I also recently replaced my 16 gb 3GS and jailbroke with blackra1n and not pwnage tool, but left out blacksn0w. Also have no problems.

If blacksn0w is not installed and you are having problems i do not know if it is to do with blackra1n or the myriad of other programs that are installed.

I do believe, however, that blacksn0w causes random signal drops, during calls and during idle as well. I had it installed along with nothing else, tested with both blackra1n and pwnage tool, and noticed this behavior consistently.
 
iphone 3G unlock & JB using Blackra1n calls drop problem

Guys, I have a similar problem as above, I have iphone 3G with JB and unlock using Blackra1n and BlackSnow. All my calls get dropped when the phone locks. When I wake my phone up I see missed calls listed. When the phone is active it shows full signal, I think when it sleeps the signals drop out causing calls to drop. Does any one have a solution to this problem yet? I would really appreciate your time in responding this. Thanks.
 
I'm using a factory unlocked 3GS with blackrain, obviously no black snow, and have lots of call drop outs
 
Help!

I used the jailbreal blackra1n . . .Now i have NO SERVICE. . . none of my At&t account information is showing on the phone.

Hi, i've been having the same problem for a while, started happening after I Got a 3G plan for my 3gs. Before that it always worked Ok with normal gsm running 3.1.2 blackra1ned and sn0wed. I think when the problem happens the whole network is getting reset on the phone side, since my Bluetooth also went off on one occasion(i just happened to randomly notice it)

Which application did you remove in order to get rid of this? I removed mostly everything unimportant that starts with an "I" and it hasnt happened but not sure if that was it.. This is really puzzling
 
It seems you can still have this problem on the 5.6 carrier, if you 'make it ra1n' AFTER you update to the 5.6 ipcc. So, you have to reload the AT&T 5.6 Carrier Update after the jailbreak...I am not even sure why, but tethering, VVM, MMS, and Cydia all work without signal drop after I did this:

1. open Console and type:

defaults write com.apple.iTunes carrier-testing -bool TRUE

2. go to iTunes and option+click check for update and load:

/Users/[computername]/Library/iTunes/iPhone Carrier Support/ATT_US.ipcc

3. REBOOT YOUR PHONE...or you will be sorry

That is all, hope it helps somebody
 
man i'm confused...:(

I've a 3gs 32gb(fw 3.1.2, bootloader 05.11.07) - jailbroken with blackra1n and unlocked with blacksnow...

I've noticed a fair few signal drops and quite a lot of the time when i'm in an area with 3g coverage i loose signal and it reverts to edge.. quite often i get the little blue dot next to my o2 logo and i have no data facilities at all? It seems to happen indoors more so than outdoors for some reason :confused:

Also having done speedtests i've noticed that 3g data rate is quite low (30-40kbps download)

I have no idea what all this ipcc stuff is... can anyone enlighten me?
 
I'm having the same problem with both a 3G and a 3GS on both AT&T and T-Mobile. Removing the unlock on my AT&T 3GS fixes it but that's not really an option for the 3G that I am trying to give my sister (she is on T-Mobile).

If the problem is this common, it scares me to imagine that none involved in the unlock scene even acknowledged it in three months. Is it that GeoHot and DevTeam know that there is nothing they can do? I wonder...

Why are you implying the DevTeam is responsible for problems with Blackra1n/Blacksn0w ?

**************************************************************************

A word of advice to everyone in this thread:

Pwnage Tool has been shown to be a much more stable jailbreak tool overall than Blackra1n.

If you do not need to unlock and do not have the new bootrom, I recommend you use Pwnage Tool 3.1.4 to jailbreak firmware 3.1.2. But, you will need access to a Mac or get a pre-built IPSW from the internet.

If will clear up all these issues you are having.

If you have the new bootrom, or need to unlock and have baseband 5.11.xx, then for now, you must use Blackra1n/Blacksn0w.

According to MuscleNerd of DevTeam, they are working on Redsn0w 0.9, so if they complete that, there may be some new options in the future.

Question/clarification about this dhlizard....does this work on a 3Gs week 46 (purchased 12/26) on AT&T? I could never get it to work, and had to use the Apple file. I always got an error 160x, no matter what I tried. I know (or at least read and understood) the error 160x is usually a USB issue, but I tried rebooting everything (several times), using different USB cables, different USB hubs, latest iTunes, etc. etc. This on Mac OS X MacBook Pro. Searched all over here at MR and at MMI to see what to try.

I ended up just using blackra1n for ~2 weeks with no problems. Note that I'm not really 'green' at JB'ing. Started back at v1.1.x with a 2G. Never had this issue with Pwnage Tool ever (and always used it) . It was only an issue with that week 46 3Gs.

BUT, it's all a moot point, for me at least, as that iPhone got returned to the Apple GB on 1/4/10.

Long story short, I've started having this problem (1st time ever) over the past week with the refurb. The refurb is a 3Gs running 3.1.2 on AT&T. I set it up as new, and didn't restore at all. It's a new SIM card also. The refurb is not a tethered jailbreak. I just used blackra1n, as that was worked on the other 3Gs it replaced, didn't even try Pwnage 3.1.4.

Been searching and reading all day yesterday on what to try. FWIW, I don't blindly just try something....the restore, even set up as new, takes 2-3 hours for me (even with using pkgbackup).

So, seeing the post by winstonzeddemor above....got me thinking as it was the scenario that applied to me. I was about to ask if anyone had tried it....

But, I also figured that the ipcc file also gets redone by using the sinful tethering hack (just with the added tethering)....so I just did that, as I've seen that the tethering method works for many.

No issues so far, tethering works, but it's only been about an hour. When I start having the 3G dropout or the 'No Service' issue, it usually happens randomly 2-3 times a day. I have to do all sorts of reboots and turning on/off of the 3G toggle to get it back, although I've noticed a couple times it did it on it's own sometimes.

Any thoughts?
 
I think someone should bring this to Geohot's attention, he might have some suggestions or at least be able to guide us on what to try
 
I don't think the problem exists just with blackra1n, unless it is a hardware and/or SIM card issue that 'carries over' after a restore.

I just went through a restore using a custom IPSW I created for 3.1.2 (7D11) for my 3Gs refurb (untethered jailbreak) via Pwnage tool 3.1.4.

Yes, I used the 'Setup As New' at the end of loading firmware, NOT a restore.

Started having the 'No Service' and 'Searching' issue as soon as the iPhone was rebooting for the very first time after updating the firmware.

This reboot was before I even got to restoring Cydia apps and themes.

Did not run blackra1n at all.

I recommend restoring to official Apple 3.1.2 and use the phone to see if the issues happen while not jailbroken.

As a note, I always do a full restore to official Apple firmware between jailbreaks. Then I start fresh every time, I know I have no hardware issues if everything works while not jailbroken. Takes a little more time, but the benefit is I can always go for months jailbroken and never have the 1st issue. Have two 3GS and both work flawlessly using this method and have for 5 months now.

I was already thinking of going back to the original 3.1.2 unjailbroken setup (no restore - setup as new) just to see what happens. Probably this weekend when there's more time. I'll just keep toggling to 2G when/if needed tomorrow. I'd like to see if the problem is 'worse' or any different than what I was having with blackra1n jb on this refurb iPhone. I may even swap in another 3Gs SIM (active) to see if the issue follows the SIM card.

I was quite bewildered seeing it searching then go to 'no service' right after a restore (and after activation) with an IPSW just created using Pwnage tool.

This is my 8th iPhone on my AT&T account, all jb'n using Pwnage tool (with NO problems until that new iBoot and now the refurb). I still have 2 other iPhones active (a 3Gs and a 3G with valid AT&T SIMs) jb'n with Pwnage tool running no issues ever.

on the contrary. They both serve the same user base with the same concerns. Just like they are quick to point out when a bug is actually Apple's fault, I would expect them to at lead. Acknowledge a "competing" solution's faults (not to sound ungrateful) to promote their own. I'm saying that it's almost as if they are unable to do it better, as if it's a fundamental flaw in unlocking the latest baseband and there's nothing either team can do about it. That's why it "scares" me... I've already updated four phones (no Mac or pwnage tool).

I had that problem with one of my older 3G phones. The only solution was to ignore the guides saying to place it in DFU mode and load it while in regular restore mode instead. Even after fresh official restores, pwned official restores, or pwnage FW loading, it still wasn't possible to load pre-made Pwnage FW files in DFU mode without getting the 160x error. It was a source of frustration for weeks. The phone worked great otherwise but I eventually had to get a replacement for an unrelated problem and those issues went away, so there was definitely something different about that phone.

An update....most of the day today I had NO problems on 3Gs 32gb with yesterday's restore via an 3.1.2 (7D11) IPSW created with v3.1.4 Pwnage tool until I changed towers. Then, I had the 3G 'No Service' message for several hours no matter if I toggled 3G on/off, rebooted, toggled Airplane mode on/off, or whatever I tried. Even when I went back to the tower (near my house) I still couldn't get the 3G signal back.

So, I swapped SIM cards with another 16gb 3Gs on our plan.....and same problem with no service on my 32gb 3Gs. And, the SIM in my 32gb swapped into the 16gb, worked perfect. I could toggle all the network settings and had no problems (note that the 16gb 3Gs is running v3.1.2 jb via blackra1n).

The 32gb 3Gs is now restoring to 'setup as new' stock firmware to see if the 3G 'No Service' issue persists (and maybe is now (or always was) a bum hardware version refurb)....
 
just drops all connection, blanks to no service, then suddenly comes back to 3GFull

Hi,

Got 2 iPhones 3.1.2 with Rogers (Supported Carrier in Canada).

Service is perfect until i JB/Unlock them (Blackra1n/sn0w):

After JB/Unlocking it with Blackra1n/sn0w, every 5mins or so it just drops all connection, blanks to no service, then suddenly comes back to 3G Full service.

I have tried this with both OLD and NEW iBoot.

Please help! This is ONLY happening once i JB/Unlock the phone works fine otherwise. :mad:

Hope someone will catch this error as it is happening with a few people around me as well.:confused:
 
Both my buddy and I had the no service drop outs when using blacksn0w (to get tethering). I'm on 3gs and he's on 3g.

We finally had to restore fresh it got so bad. Now, I'm jailbroken but not blacksn0w'd....and the phone is just fine.

And Myfi from the cydia store is a nice tethering alternative that works well and even allows you to set up a wifi hotspot.
 
Hello - I am a relatively new iPhone user and I need help with tethering. I am on AT&T and originally jailbroke my phone with blackrain and then used blacksnow for tethering. I too had numerous dropped calls so I uninstalled it and reset to my factory settings and now the dropped calls has gone away. If I understand this correctly, do I just need to jailbreak my phone and not unlock it since I'm with AT&T? If so, what do you suggest installing to enable tethering and not have dropped calls? I'm running XP on my PC. Is Cydia the best? Any suggestions would be appreciated - and steps how to do it would be most helpful!! Thank you everyone - I really appreciate it!!

Restore to factory settings
Jailbreak with blackra!n
Do NOT do the blacksn0w option
Download Cydia
purchase Myfi from Cydia. It's easy to use.
That's what I did and it seems to be working fine now.
