Blaze 4G only radio working on Tmo i727 JB?

There has been some very good information in this thread.

I did try a few radio mods for my unlocked i727 on Tmo (CM10) and I ended up with a lot of "Mobile network type: UNKNOWN:0, unknown phone number, unknown IMEI, etc." Blaze_4G_LB7_ICS_Radio_MOD was the only one mentioned here that that worked at all, and seems to work better than the UCLE I was running before, although I'm still testing (also baseband reads "unknown" in settings -> about phone, which is annoying).

I will, however, vouch loudly for the dd method of flashing the amss.bin/mdm.bin files as root (mentioned in this thread by duckpond). I'd forgotten that the dd binary was available on Android :) Depending on your device you might want to adb shell and cat /proc/mounts to make sure the amss/mdm files are being copied to the right device paths, but otherwise it's a very fast, clean method.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Thumdar:
Is there a consensus yet?

Cell phone dev newb ~ first post!! :cyclops:

I've read this entire thread and must admit, I'm confused.

Yesterday I bought an AT&T Skyrocket i-727, rooted it, inserted a T-Mobile SIM and unlocked it using a cellunlocker.net code. Today I activated my T-Mobile account and all is working except I'm stuck with the EDGE (2G) worthlessness (and can't use hotspot). Clearly I need to flash my radio/modem (new technology to me) and I've never flashed one before.

Phone specs:

SGH-i727 AT&T

Android 2.3.6

Baseband UCLA3

Kernal 2.6.35.11

Build Gingerbread.UCLA3

So I guess I'm asking, is there any consensus on which is the most stable (best?) radio to date? Blaze? Telus? My main reason for buying this phone is for wifi tethering and am not too concerned if I need to charge it frequently. A stable 4G signal is what I'm after.

BTW ~ very cool forums! :good:

You should change your apn
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Thumdar:
Thanks Ninja.

I see the differences of the two being:

Name going from T-Mobile US to just T-Mobile

Most of the other settings no longer having "not set"

The addition of "MMS protocol: WAP 2.0"

My APN type is internet + mms + supl

Pardon my newb ways but, do I need to add the "MMS protocol: WAP 2.0"? Not sure how to do that.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] whassupmyninja:
I dont think you would need that., try them one by one and see what works and enables you 4g. The first post links of where i found the info and a thread to one. Search on google if those don't work :)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Thumdar:
Yeah, uhm.., thanks.

So ~ is there any consensus on what the most current, suggested, stable radio/modem is to flash?

This guy (on a different forum) is saying it's useless to flash the radio. Not trying to start a war, just offering food for discussion:

It's not useless. I'm running the blaze 4G MOD radio and for T mobile, as it works better for me than the stock radio
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] sybaek:
I'm running R4INS AOKP Milestone-1 Jellybean Oct-30 build on my unlocked Skyrocket. I'm currently have the T879UVLG3 radio. I'm able to connect with HSPA+:15 using that radio. Unfortunately I live in a remote town, and I cannot verify the download speeds. Where I live I can only access 3G, so at 3AM (lowest load on the local towers) I am only seeing 50kB/s down and 100kB/s uploads. I do however get the little H+; my speeds are just 3G speeds. I've flash most of the radios around here and the UVLG3 radio and UVLE1 radio seem to give me the best reception and consistent speeds.

I think later today I will flash back to seanscreamz's last SkyICS and try a few other radios and see if I can do better. But in terms of what radios you can flash, it's sort of trial and error. The T989 radios are compatible with varying degrees of success. I had no luck with the Blaze 4G LF4 radio, it would give me an "unknown" baseband. Of course, all of my findings are based on running a JB rom, and experimenting has shown that ICS radios for the most part do not play nice with JB roms.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] lesd777:
I see some of the tmobile radio links for radios are no longer valid. Is it safe to go to the T989 forum/radio thread and download the file" SGH-T989 UVLH1 (T-Mobile) 4.0.4" ? I'm on CM10 ParanoidAndroid and the blaze 4G mod gives me the fastest speeds but the reception sucks and drops calls. However if i use the Bell modem i get much better call reception(signal), but the data speeds are way low ( ~50kbps).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] That KiD Beto:
So what is the best Jellybean combo? I hated having to go back to ICS to get decent speeds. I currently am using SKY ICS with the Blaze modem.

i just got my unlocked at&t s2 727 repaired, it didn't power on so samsung replaced the PBA (mainboard?). when i got the phone back, the phone was locked again..but the same sim unlock code worked.

i didn't flash the radio for t-mobile, but it seems to be picking up 4G and under t-mobile network type, it says HSPA:11. my baseband radio is I727UCLI3. does this mean for my area, this radio rom detects tmobile 42mbit+ and no Blaze radio is required anymore with this phone in order to work on t-mobile AND at&t LTE?

thanks
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] rjohnstone:
T-Mobile is repurposing their EDGE 1900Mhz band to support HSPA, so you're most likely in an area that had this conversion done.

My daughter's iPhone 4 is on T-Mobile prepaid and we noticed the E switched to 3G about two weeks ago.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] thekurrgan:
This phone is essentially the T989 with an LTE radio added any way. It was created with the TMobile merger in mind, and was an AT&T handset that could use all of the available bands after the merger was complete. Same reason the T989 supports 850/1900 and is a TMobile device.

I've been able to get HSPA+ working on Tmo with my skyrocket using all of the radios listed, however I have noticed that the LTE radio stays turned ON. While it is obviously unable to connect to anything, it is polling for an LTE signal.

This should not be the case, as when I use the Sky specific radios, the LTE radio "Parks" after it determines there is no LTE signal available.

I can see it pulsing out at what I would venture to guess is maximum power every 8 seconds on the LTE band. (I've got some pretty nice RF testing equipment from my HAM days, not to mention cellular specific stuff from my tower contracting days)

What I'm wondering, is if any one has tried and flash the T989 ROM on to the Sky Rocket and had success. My running theory is that the RIL is making some sort of call for an LTE specific request even if it is as simple as "Hello are you there" and it starts the LTE radio up but never shuts it off. I'm theorizing that the T989 rom which would have an RIL native to the radio sw being used may not make any such call, and therefore never activate the LTE portion.

It would also give us the WiFi calling and what not.

Thoughts?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] jose makalolot:
I have been using T989 roms, radio, and kernel. My only issue is it tries to connect to UMTS first before connecting to HSPA. This can be observed by using juggernaut rom and choosing 3g icon for UMTS and 4g for HSPA. Also, it sometime hangs on arrow up and loses data connection. Not sure what's the issue. Also, I get slow upload speed. Tried most of the builds/combos already.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] thekurrgan:
I flashed a T989 ROM. LTE pulses are still there.

I get the UMTS pause before HSPA as well, however I am fairly sure its mis reporting to the RIL since speeds dont support the UMTS indication.

All in all, I'd say this would work if you are just hell bent to use the Skyrocket on TMobile for whatever reason, but its certainly not as solid as a standard issue Tmobile phone. Of course, any one willing to do this in the first place is not concerned with the minor issues that it may present.

I'm an AT&T user in the first place, however TMobile recently expanded to my area. So far they suck..1700 & 2100mhz doesnt work well in the mountains..So I'm on GSM/EDGE most of the time with the Vibrant i've got to try them out.

WiFi calling is pretty damn nice though, I do wish AT&T would implement that.Visual Voicemail is also something AT&T should implement on their android phones.

Thanks to the OP for posting this. Lead me to have some fun!

Well I didn't try a T-Mobile firmware however the radios do work fine with normal skyrocket firmwares. skyrocket firmware does offer all modes such as lte hsdpa and GSM. But tmo roms will still offer hspda and GSM only modes. So try switching to hsdpa only mode.

THANK YOU!

works fine for me with the T-mobile SGH-T989 VK1 flash and running SKY ICS rc7.4

after some fine tuning im getting close to 10mbit up 2mbit down... INCREDIBLE...

battery life is crap though still looking what the issue is here.

Does the device intelligently disable the mobile data when connected to wifi? is there an app?

also when looking at "mobile network type" in settings in seems to keep jumping between UMTS and HSPA... could this be auto thottling down when there is no traffic? i am just curios if this jumping is causing a massive battery drain...because its sending those "hi are you there" type of signals every couple of seconds...

If you're serious about wifi calling get grooveIP it works flawlessly over wifi and uses your Google voice number...no cellular minutes/connection needed. Was awesome yesterday when I got off work and had no service at all on all of my lines. Started up grooveIP and called and *****es out T-Mobile from my old g1 with no sim card installed. Yeah I like having options. Thinking about picking up an epic 4g to replace my aging g1 as the house phone.

I think both mobilicity and wind let you try a sim in the store, so flash a T-Mobile or a Telus JK3 modem (or keep both on the phone so you can switch between). Then go into a mobilicity or wind store and ask them to try a sim remember to make sure the APN is valid for whichever provider you're going to try. Run a few speed tests and see if the performance is acceptable.

I will probably flash a T-Mobile radio later since T-Mo AWS coverage is still broader. But, for people in any of the refarmed 1900Mhz areas that don't want to switch out their rom or radio, the speeds seem acceptable.
