Hacked AT&T Carrier Update Could Improve Your Network Performance

Joseph Brown, who recently released a hacked T-Mobile Carrier update with Sky Zangas, has now released a hacked AT&T carrier update that allows the iPhone to connect to the band giving off the strongest signal rather than the preferred band, both with LTE and HSPA+.

This could improve network performance for some users. Here's how it works:

--
This hack enables Release 9 DC-HSPA+ on the iPhone 5 and iPad 3, 4, and mini as well as enhancing LTE data and signal. Though AT&T is limited to HSPA+ 21, the device itself becomes more open to an increased amount of bandwidth thus allowing for better throughput of data and data connection. This is very convinient for users in areas that don't yet have LTE coverage. This hack also includes a fix to any and all iPhone 5 users who have experienced degraded/weakened signal over the past couple to few months on the PCS 1900MHz and/or CLR 850MHz bands for HSPA+ as well as the APT 700MHz and/or AWS 1700MHz band for LTE.

The issue was due in part to the newer revised iPhone 5's that came with the AWS band enabled for HSPA+, if you were to ever choose to leave AT&T for T-Mobile. It set the band preference for HSPA+ to CLR and LTE to APT which can cause conflictions and problems when you're in an area with towers on different bands with stronger signal. The setting has been set back to the default “auto” setting and should help the 4G HSPA+/LTE signal perform a bit better, whether your iPhone 5 is the older edition or the revised edition. This hack will also help you connect to the strongest tower rather than the preferred type of tower, whether on HSPA+ or LTE.

Hey joe, I have an iPhone 5 bought from the Middle East and I need a carrier package for AT&T that the VAR enables facetime. All is carriers don't specify that facetime to be active but on the Middle East phones it has to. Is this something you can do? Can this do that?

This doesn't work for me. It stopped all ability to connect to the internet using cell service.

I need help I Downloaded the new AT&T hack last week on my iPhone 5 After using it i noticed that it wasn't working for me. Also I noticed that some of my cydia tweets is not working as Tether me or mywi or pdanet. I do have IFile I Try deleting Everything it said on the description. But all I got was searching for signal I was like this for 2 days. So I had to installed the hack again to get my phone working. But I'm still having the same problem with the Curia tweets that I'm Trying to download is really important for me. Help me I need to go back to my regional settings can someone tell me. Thank you

Anything for us Verizon people?

Simon - May 21, 2013 at 11:52pm

Here is a question that hasn't been asked. Since this hacked carrier file changes the preference to the strongest signal rather than the preferred band, will it connect to a EDGE network over HSPA Plus network when it detects the EDGE network has better signal? If so, that would be very bad because I would rather have 1 bar on 4G than 5 bars on EDGE network.

I would also like an answer to this....

Joe - May 22, 2013 at 6:08am

That's not what we meant. AT&T uses 2 bands/frequencies for both HSPA and LTE. Rather than the phone being limited to one of each of those bands, we've enabled auto band selection mode so it picks the strongest band if you're on HSPA or LTE. This WILL NOT drop you to EDGE.

Simon - May 22, 2013 at 9:55am

Thanks for clearing that up.

christian - May 21, 2013 at 3:02pm

Can someone please assist me, my iPhone is stuck on searching after using the revert guide for the Jailbroken iPhone. I have tried all the methods of rebooting and turning off/ON settings nothing is fixing this. If anyone has the original carrier update file for the iPhone can you please upload.it and shoot me a link? Thanks

Petr - May 21, 2013 at 10:07pm

Here is how to find original att 14.0 , it is on your phone: "Yeah i was able to fix it. You'll need to use ifile if you have it and you're jailbroken. Also follow the revert steps which were : Jailbroken users will need to navigate to var/mobile/Library/Carrier bundles/iPhone or iPad and delete the ATT_US.bundle folder entirely as well any files located in var/mobile/Library/Carrier Bundles/overlay. This however didn't fix it for me. Thankfully ios stores all the original stock bundles in /System/Library/Carrier Bundles/ Find the att bundle there and copy it to var/mobile/library/carrier bundle/iphone or ipad if you're using iPad. reboot your device and you'll be back on stock ATT 14.0 hope that helps you."

Jojos - May 21, 2013 at 11:56am

That worked perfectly. Followed ur Mac instructions on iTunes 11.02... & had no issues. In fact it completed so fast I wasn't sure it worked till I checked the AT&T version (changed to 14.1). It increased both my WIFI & Cell connection by 5-10%. Thanks Again Joe!

Jojos - May 21, 2013 at 12:41pm

I've actually just checked my speed & it seems I under rated my increase in speeds.. B4 doing this hack here r my speeds. Download = 13.59mbs,Upload=1.83mbs,& Ping=280ms My new speeds after the hack r. Download = 6.66mbs,Upload=.83mbs,& Ping=91ms Absolutely Amazing!!!

70d79c2 - May 21, 2013 at 1:27pm

Jojos, I don't get it? Besides the fun 666 reference, your speeds are half of what they were; only your ping time is a bit faster... I'm confused.

Jojos - May 21, 2013 at 3:36pm

Ur right I reversed the numbers. Sry my dyslexia kicked in bad!! LOL!!

Avenged110 - May 21, 2013 at 5:00am

Anyone notice anything different about battery? My phone does drain noticibly faster than before but it's not bad enough to warrant the massive inconvenience of restoring. And I have rebooted multiple times.

Brian - May 21, 2013 at 12:22am

Is there a way to do this through ifile? Please post instructions.

techieguy - May 20, 2013 at 11:29pm

Confirmed; working flawlessly on jailbroken iPhone 5 iOs 6.1.3. Speed does increase as I am using Personal Hot Spot (off course it's free) using Tether app in Cydia. Thank you so much to the creator. Anyone who is interested should try and give the gentleman credit. You need to follow the steps and if you have problems, the revert instruction is right there.

Joe - May 21, 2013 at 2:25am

Thanks for the great feedback and positive words! :) Follow me on twitter: @joe012594

Jojos - May 20, 2013 at 9:27pm

Hey Joe, Which version of iTunes is best to use?And does the ios version matter?

Joe - May 20, 2013 at 9:29pm

I'm not too sure about the newest version of iTunes that just came out but it should work on all version of iTunes and iOS that support the iPhone 5. :)

Bugged Out - May 20, 2013 at 11:17pm

Didn't work on latest iTunes, win7x64 :( Command line doesn't start iTunes, nada.

Joe - May 20, 2013 at 11:33pm

It's not supposed to start iTunes. Only activate carrier testing. If you didn't get any errors then it should be working.

Simon - May 20, 2013 at 8:46pm

Anyone try this on a phone with straight talk? Straight talk is a AT&T MVNO. So it should work.

Joe - May 20, 2013 at 9:28pm

Straight Talk is so limited that it won't make a difference. Trust me on that.

Simon - May 21, 2013 at 1:34pm

Limited how? They use AT&T's HSPA PLUS NETWORK. just no LTE. why wouldn't it make a difference?

Mat - May 20, 2013 at 8:10pm

I don't goin to touch my jailbreak u crazy why u guy no make a cydia tweak ????

Joe - May 20, 2013 at 9:27pm

Is anyone forcing you to do this? I don't have the resources to do it as a jailbreak tweak as I don't own a repo nor am I jailbroken. Also, it wouldn't be fair to keep regular users out of the loop either.

angel_92701 - May 20, 2013 at 10:20pm

I have a jailbroken iphone 5 and it work just fine . 6.1 att 14.1 not sure if it will increase the sped. i usually get on my area 36 and up. but after the update still working without a problem. so far

Jayzy Briones - May 20, 2013 at 7:57pm

where could i download this? site is down already

Joe - May 20, 2013 at 9:25pm

Yah, Iknow. Sorry about that. We had so much traffic that it crashed the entire website. It's back up now and be accessed through itweakios.webs.com or itweakios.com. Thanks! :)

Metalstorm74 - May 20, 2013 at 6:45pm

How do you know for sure it "took"? I did the hack last night, says went thru on iTunes, but where can I see a chance in the phone? I can put the phone in "field test" to show which sites, and LTE bands I'm using, but is that the correct place? BTW for field test mode dial *3001#12345#* then call...

Joe - May 20, 2013 at 7:11pm

Go to Settings > General > About and if it says AT&T 14.1 then you did it successfully.

Joe - May 20, 2013 at 3:18pm

I experienced one problem is you guys have microcell DON"T upgrade. You will loose your microcell connection.

Joe - May 20, 2013 at 4:41pm

This hack doesn't get rid of M-Cell. If you read earlier in the comments then you would've seen that. It still works. It just doesn't show M-Cell in the carrier logo is all. No big deal.

Avenged110 - May 20, 2013 at 8:19pm

I'm actually really happy it does that haha I was suck of seeing m-cell up there.

Clive - May 20, 2013 at 2:43pm

Tried the hack and got nothing but searching..... Did a restore and thank god it came back. I have an iPhone 5 thats just a week old that was on 6.1.3. The restore updated the version to 6.1.4. Now all I have to do is rearrange all my apps the way I like (sigh)

James - May 20, 2013 at 3:34pm

You didn't have to restore. There are ways to update only the carrier update without restoring. It's actually quite simple if you googled it.

Clive - May 20, 2013 at 3:43pm

I did not know that was possible. Thanks for the info.

Ken - May 20, 2013 at 5:57pm

Where can I download the original carrier update file?

Simon - May 20, 2013 at 1:37pm

I'm on straight talk (AT&T pre-paid) HSPA . I wonder if this will improve my connection too. Afraid to install it since I'm jailbroken. Would hate to lose my jailbreak if I had to restore.

Alex - May 20, 2013 at 2:03pm

Wait for jailbreak instructions and files (.pri). That way it's easy to fix. The way it is now, it's very likely to mess up your jailbreak when you lose modem.

Joe - May 20, 2013 at 4:45pm

Not ganna happen Alex and here's why. This creates an entirely new carrier bundle. The bundle currently used for AT&T iPhone 5s and iPads is located in System/Library/Carrier Bundles/iPhone or iPad. The new bundle is located in var/mobile/Library/Carrier Bundles/iPhone or iPad. Completely separate bundle locations of which have nothing to do with each other.
