Sprint Carrier Update Hack (for iPhone 5 Only)

Recommended Posts

Over the past month or so there has been hacked/tweaked carrier updates released for all the major carriers in the US. iTweakiOS just released the latest one for Sprint. It supposedly increases 3G (not LTE) speeds. I'll be trying it out when I get home tonight and will report back my results.

 

Note: This will work on iPhone 5's that are not jailbroken!

This hack enables 1x Advanced and EVDO Rev. B on the iPhone 5 enhancing EVDO 3G data speeds. Though Sprint is limited to EVDO Rev. A, the device itself becomes more open to an increased amount of bandwidth thus allowing for better throughput of data and data connection. Already intact coding within the carrier files also showed signs that Sprint has 1x Advanced support on their network. So, how knows? This may actually enable something new. Throttling code was put in place to limit users to a certain amount of bandwidth on 3G only as well and has now been removed. As for LTE, no throttling codes were put in place to limit users' bandwidth nor was any band preference coding put into place to limit users on coverage. This won't increase signal so don't expect it to like the AT&T version of this hack nor does it increase LTE as it was not limited in the first place.

i don't understand how it works but i will try it.

 

Also i will do speed tests pre and post (i will make it a sample).  I will average the speed tests and see if hack worked.

What I want to know is whether this is a signed profile or he just found a way to install an unsigned one, because this is just a compressed bundle and it contains the PRL, etc. If this works unsigned, then it means we can change the PRL without jailbreaking.

This isn't a PRL. It is a carrier update file which is what allows for some low level customization of the phone (such as FaceTime over cellular, hotspot functionality, and things like that).

I just applied this to my iPhone cant test at my house as i have LTE in my area (South St. Louis/ Tower Grove Area) but i'll post updates tomorrow! I work at sprint in Ofallon and 3G data speeds out there are terrible as of the past couple months so im hoping this helps!

I never believe these fixes as there isn't a problem with the device being limited if it can max out the Evdo airlink or LTE without mods. The problem is due to having to share the airwaves with all the folks running speedtests.

Can someone post a speedtest , I want to see if this is worth me doing .

 

I can bet you it's a big fat negative...placebo affect.  Plus what's a speedtest going to tell you with all the variables in place?  You'd have to do this in a controlled environment.

..... Anyways back to what I had asked before.

So, it enables Evdo Rev B, which will do nothing for Sprint. It enables 1XA, which does nothing currently.

 

So the tweak does nothing?

1xA should already be enabled.  Or maybe that's why the iPhone is shunned from using 800SMR first like all the other phones.  The funny part is 1xA is going to absolutely zero for your speeds.

I've heard conflicting reports as to whether or not the 800 MHz signal I'm connecting to is 1xA.

 

Either way, my point stands. If it's not enabled, this tweak does nothing. If it is, it still does nothing without an appropriate signal to connect to, as you mentioned before about the iPhone 5 lacking SMR in its PRL.

Not lacking.  It finally has the ability to use 800SMR but someone at Sprint decided they didn't want the iPhones sitting on the 800SMR channels like other phones.  So the iPhones only use the 800SMR if there is no PCS signal at all.

No hack can speed up Sprint's 3G. 3200kbps is the full on theoretical max data rate over the channel. 

Hope that answers your question.

Thanks that pretty much answers it .

How many times do I have to tell people, I'm an iOS developer. The file is in fact an OS X compressed bundle, which you can open to find carrier.prl among other files. Normally, the phone will only accept the bundle if signed by Apple, ensuring none of the files are corrupt or tampered with. This "hack" simply appears to use a debug loading mechanism to bypass that check, so in theory we can modify the PRL. I will try it later and report back.

What about this?

 

"The hack is said to enable Release 9 DC-HSPA+ on the iPhone 5, opening the device to an increased amount of bandwidth for better throughput of data even though T-Mobile has not upgraded its network to support Release 9. The coders claim their hack bumps up HSPA+ speeds by 3 Mbps to 8 Mbps on the downlink. According to Brown, T-Mobile's HSPA+ network is capable of Release 8 downlink speed of 42 Mbps and Release 6 speed of 5.76 Mbps on the uplink."

So what's your findings good buddy?

They are likely seeing higher speeds not because of any upgrade but because their hack puts them on the less burdened PCS W-CDMA carrier(s) instead of the long standing AWS W-CDMA carrier(s).

 

Correlation ≠ causation.

Shouldn't TMO's network automatically do this?

    • So, in summary, here are the options I tested: T-Mobile intl roaming - LTE on SoftBank, routes back to the US (~220ms to 4.2.2.4) IIJ physical SIM - LTE on NTT, local routing Airalo - LTE on SoftBank and KDDI (seems to prefer SoftBank), routed through Singapore (SingTel) Ubigi - 5G on NTT, routed through Singapore (Transatel) US Mobile East Asia roaming - 5G on SoftBank, routed through Singapore (Club SIM) Saily - 5G on NTT, routed through Hong Kong (Truphone)...seems to be poorer routing my1010 - LTE on SoftBank and KDDI (seems to prefer KDDI), routed through Taiwan (Chunghwa Telecom) I wouldn't buy up on the T-Mobile international roaming, but it's a solid fallback. If you have the US Mobile roaming eSIM that's a great option. Otherwise Ubigi, Airalo, or my1010 are all solid options, so get whatever's cheapest. I wouldn't bother trying to find a physical SIM from IIJ...the Japanese IP is nice but there's enough WiFi that you can get a Japanese IP enough for whatever you need, and eSIM flexibility is great (IIJ as eSIM but seems a bit more involved to get it to work).
    • So, the rural part of the journey still has cell service for nearly all the way, usually on B18/19/8 (depending on whether we're talking about KDDI/NTT/SoftBank). I think I saw a bit of B28 and even n28 early on in the trip, though that faded out after a bit. Once we got to where we were going though, KDDI had enough B41 to pull 150+ Mbps, while NTT and SoftBank had B1/B3 IIRC. Cell service was likewise generally fine from Kawaguchiko Station to Tokyo on the express bus to Shinjuku Station, though there were some cases where only low-band LTE was available and capacity seemed to struggle. I also figured out what I was seeing with SoftBank on 40 MHz vs. 100 MHz n77: the 40 MHz blocks are actually inside the n78 band class, but SoftBank advertises them as n77, probably to facilitate NR CA. My phone likely preferred the 40 MHz slices as they're *much* lower-frequency, ~3.4 GHz rather than ~3.9, though of course I did see the 100 MHz slice being used rather often. By contrast, when I got NR on NTT it was either n28 10x10 or, more often, 100 MHz n78. As usual, EMEA bands on my S24 don't CA, so any data speeds I saw were the result of either one LTE carrier or one LTE carrier plus one NR carrier...except for B41 LTE. KDDI seems to have more B41 bandwidth live at this point, so my1010 or Airalo works well for this, and honestly while SoftBank and NTT 5G (in descending order of availability) have 5G that's readily available it may be diminishing returns, particularly given that I still don't know how to, as someone not from Hong Kong, get an eSIM that runs on SoftBank 5G that isn't the USM "comes for free with the unlimited premium package" roaming eSIM (NTT is easy enough thanks to Ubigi). In other news, I was able to borrow someone's Rakuten eSIM and...got LTE with it. 40 Mbps down, 20 Mbps up, 40ms latency to Tokyo while in Tokyo...which isn't any worse than the Japan-based physical SIMs I had used earlier. But not getting n77 or n257 was disappointing, though I had to test the eSIM from one spot rather than bouncing around the city to find somewhere with better reception. It's currently impossible to get a SIM as a foreigner that runs on Rakuten, so that was the best I could do. Also, I know my phone doesn't have all the LTE and 5G bands needed to take full advantage of Japanese networks. My S24 is missing: B21 (1500 MHz) - NTT B11 (1500 MHz) - KDDI, SoftBank B42 (3500 MHz) - NTT, KDDI, SoftBank n79 (4900 MHz) - NTT Of the above, B42/n79 are available on the latest iPhones, though you lose n257, and I'm guessing you're not going to find B11/B21 on a phone sold outside Japan.
    • T-Mobile acquiring SoniqWave's 2.5 GHz spectrum  Another spectrum speculator down! T-Mobile is acquiring all of their BRS/EBS licenses and their leases. Details are lacking but it looks like T-Mobile might be giving them 3.45GHz in exchange in some of the markets where they're acquiring BRS/EBS to sweeten the deal and stay below the spectrum screen. Hopefully NextWave is at the negotiating table with T-Mobile so NYC can finally get access to the full BRS/EBS band as well.  — — — — — Edit: Turns out this is a spectrum swap where T-Mobile is basically giving them DoD spectrum in a bunch of markets in exchange for all of SoniqWave's BRS/EBS. SoniqWave will likely turn around and sell the DoD spectrum to AT&T whenever the FCC removes the 40MHz cap.
    • Maybe. The taller buildings on one side of the street all have Fios access and the NYCHA buildings are surrounded by Verizon macros that have mmWave. I don’t think this site will add much coverage. It’d be better off inside the complex itself.
