Overcome 1.63 Rom Modem Issue

Installed Overcome 1.6.3 and Kernal 2.1.6 to my TMOUSA TAB. I also Unlocked via RotoHammer Hex Edit fix. I put in a Canadian Telus SIM card but the phone always gets signal and but it shows its on Roaming and wont make a phone call with the App. Do I need to reflash a different modem file that is compatible with Canadian Networks? Thanks!!

follow the howto unlock phone calls guide under xda galaxy tab bible, and try flashing the (modem_bell_i9000) modem.bin provided. (works great for me under overcome 1.6.4).
And if you would like to return the favor... and if you have a 5ghz dual-band router, please read my XDA post about Galaxy Tab Wireless-N at 5ghz. I could really use some constructive feedback there.

I hate to tell you this but unless you switch to Wind, you are SOL with Telus as they use the same spectrum as Bell/ATT/Rogers etc. Wind is like TMO in the states.

So the Tmobile versions don't support the other bands? If that is the case, I didn't know that.
I think Mobilicity.ca works on the same (AWS?) frequency as WIND also though.

Maybe. I can't see them working on some other frequency that nobody else uses. Maybe phone their tech support and ask if a TMob phone will work? Good luck to you.

The only way to get voice on your t-mobile tab is to find the roto modem switcher thread, and flash the roto-2g modem from there. Don't bother with the switch set up, because you won't get 3g anyway.

[Q]XT860 Radio Image

Is there a XT860 Radio Image or sbf / fastboot file that
will work on gsm (U.S. Bands, I.E. T-Mobile)?
instead of the chinese one, you know!

We have fastboot files from Brazil, Argentina and Mexico. All of these will work on an XT860 and GSM bands. Check out this thread for details and downloads:
http://forum.xda-developers.com/showthread.php?t=1370721
As far as I know, these will not give you H+, only 3G speeds. Currently the only way to have H+ on an XT860 is to be on the Bell Firmware, which we do NOT yet have an SBF for.
Hope that helps.

If you have an xt860 afaik any firmware will work on american gsm though T-Mobile will ply get edge speeds. If you have an xt862 I do not know if xt860 radio.img will work on an xt862. They have different radio hardware

As far as I know the best you can do with T-Mobile is edge speeds due to them using a band neither device ca use. I wish you the best of luck, if you succeed im sure others would be interested in your results

Thanks!! we'll see how it goes

T-Mobile uses 1700 MHz for its 3G. These phones do not have compatibility with that frequency. This is what I was trying to tell you before, when I said T-Mobile's 4G is not compatible: it's the same exact network. 3G=4G, only they call it 4G when your phone is capable of greater speeds due to more advanced radio technology, not a different frequency.
T-Mobile only uses 1900 MHz for Edge, and 2100 won't work because it's 4G only, and won't work if you don't also have access to 1700, which is for both 3G and 4G. I hope this makes sense.
I'm glad you made your own thread to deal with this issue, and I hope I am wrong and that someone more knowledgeable comes along and corrects me and tells us all how to make it work. If you figure it out I will apologize as well. However, I just want it to be clear that no one who has made gsm work on the D3 has been able to (let alone interested in) getting 3G/4G to work on T-Mobile. I have assumed it is because it's an incompatibility problem between the hardware of these phones and the network you're trying to use.
Even if you had an xt860, it wouldn't work on 3G on T-Mobile, so using their radio.img and build.prop won't help on the xt862. Just because you can flash them doesn't mean they will work.
By all means, please post results and let me know if I'm wrong. As I said, I would prefer to be wrong in this case, but I don't think I am.
By the way, the xt883 radio.img shouldn't change the functionality of the phone beyond letting it connect to gsm in the US. I really don't see what your gripe is with it. Not that I'm offended or something; who cares. But I use it every day and haven't seen any results worth frowning over, let alone trying to switch to the xt860's which is not at all compatible with CDMA.

That's how i've understood it, our devices lack the 1700 band. It will work on t-mobile network, but only at edge speeds. I do believe this has been tried. I also don't think an xt860 radio.img will work as expected on an xt862, but i wish him the best of luck. I would like to use t-mobile when i travel to the states, they have a really good pay per day plan compared to others i looked at(although for a week at a time i can live with edge speeds). and yes, xt860 is GSM only if the flash does work there will be no CDMA functionality

Open in a Hex Editor to compare. I don't think they are the same... I took apart all of the files in the latest Bell update with no success, as well I tried dd'ing all of the different partition blocks to my phone just before sending it into the shop to get Bell firmware re-loaded onto it and didn't get any luck... in the end it was basically an encrypted bootloader problem.
If we can get the phone bootloader-unlocked we *might* be able to use some of the dd images that were created (I have each partition from bell 2.3.4) flashed through RSD then do the upgrade to the latest Bell, which overwrites the radio and boot partitions...
Let me know if anybody is interested in them. Please note, they the whole partitions and have extra padding on them. Also, I think I missed /preinstall, but I can't remember.
I created a new thread for this... again it's the original Bell stuff 2.3.4. I can probably do the same thing for the current Firmware as well.
Please see http://forum.xda-developers.com/showthread.php?t=1449027 for the 2.3.4 dd images

Vivid for T-Mobile 4G

Have anyone got HTC Vivid worked for T-mobile 4G. I always get "E". I heard LTE (1700/2100) can be used for Tmobile 4G after flash a tmobile 4G radio. Is this kind of radio available for Vivid?

That's interesting. Does you Vivid show 4G icon? How do you know it is 4G.
T-mobile uses UMTS/AWS: 1700/2100 Mhz for 3G/4G (not really 4G though), while Vivid 4G in AT&T uses LTE/700 MHz Class 17, 1700/2100 MHz. I don’t think you can use Vivid in T-mobile 4G, not even 3G, unless you flash a correct T-mobile radio.
I think the most possible working radio in Vivid for T-mobile 4G is HTC Amaze. It has UMTS: 850, (AWS) 1700/2100, 1900, 2100MHz. I am not daring to try it.

"H" icon and speedtest give speeds of 8-10mb/s down and 2mb/s up, faster than what my T-Mobile G2 was giving me.. i think on stock ics rom it was showing 4g icon but i havent used it in a while

That's weird. I don't know how you can get 4G. I hope someone (Dev) can explain it. I always get "E" with 150kb down and 120kb up. I am in a stock ICS though. There was a thread discussed the possiblilty:

I have no clue what the ramifications are. Are the platforms the same?
I'm still interested in what combo is used above.

So I pulled radio.img from the Amaze factory ROM: RUBY_ICS_35_S_TMOUS_2.14.531.3_R2_Radio_1.14.550L.17DC_30.78.550L.15_release_262141_signed.zip
According to this, the radio is 1.14.550L.17DC_30.78.550L.15. I did a fastboot flash (fastboot flash radio radio.img) and it did it, had progress bars on the screen, and the cmd prompt windows said OKAY. However, when I go into Settings > About Phone > Software Info > More, the Baseband still shows 3.02.4740.14_34.22.701040.19, and I still have the E at the top.
It was worth a shot...
**EDIT**
Fastboot output:
Code:
fastboot.exe flash radio radio.img
sending 'radio' (21997 KB)... OKAY
writing 'radio'... OKAY
I get the green progress bar during sending, and then the red progress bar during writing, so I thought it worked.

All in the screenshots.. ive not changed out the radio at all, using Virtuous Inquisition and at the time it was probably one of the older Kozmic kernels

Same baseband as mine. I might try this ROM & Kernel combo to see if I get the H. You said 'at the time', are you using a different combo now and still getting HSPA+?
Another question I had was regarding your SMS issue, do you still have it? Mine generally works for a few days, the any SMS I send is stuck in 'Pending'. If I reboot, the first message (or oldest in the queue) will go out, but no others. If I do a full wipe in recovery, SMS works again.

still using kozmics kernel, just updated and i still get hspa+, as for the sms issues, yes i still have the problems where it gets stuck on sending and even when i restart that txt usually does not go through and i end up having to do a factory reset or restore a backup and it works again for a while, then quits..i just rinse and repeat when this happens

Gonna test the ROM & kernel shortly. Was hoping for a fix for the SMS issue, but been using gvoice as a workaround.
---------- Post added at 02:17 PM ---------- Previous post was at 01:45 PM ----------
Running Virtuous Inquisition v4.0.2.1 & KozmiKKernel RC2 and still only have the E. I tried changing the bearer for the APN to eHRPD & LTE, but I lose mobile data, I have to leave it as Unspecified.
What does it show for Mobile network type in Settings > About phone > Status?

Man this SMS issue is annoying. Took backup, full wipe, loaded Virtuous ROM, SMS worked fine, backup of Virtuous, wipe, restore of Stock ICS, no SMS

when im at home i usually get stuck on edge only..when i leave home im able to pick up 3g and 4g..took these screenshots today while i was out

That's awesome. Maybe I didn't leave mine on long enough? On the Note & Skyrocket threads, people mentioned signal degradation. I normally only get EDGE inside my work, but 4G outside the building. I tested outside the building, but reflashed to stock after. The non-working contacts autofill killed me. Now the no sms is killing me, maybe I'll try virtuous again shortly.

Only difference I see is that ? in the square after T-Mobile, and 0 dBm

The XT883 radio is ONLY required if you're using domestic GSM, such as AT&T or T-Mobile. The XT862 stock radio has an MNC block on 310 (US gsm carriers) but will be unlocked for all foreign carriers, this ensures the D3 is not used in the US on major competitors
Also, if you test the XT883 radio.. why not just reflash the stock radio instead of an entire SBF? I've done this several times. Just make sure you have a backup of the stock build.prop and restore as you flash radios. I have a build.prop.cdma and build.prop.gsm in /system and just take off the corresponding type for the one I want to use. I've uploaded the stock XT862 radio before.
I currently use the XT883 radio and have no issues with connectivity, I've also written a build.prop for use with the XT883 radio on kexec roms and has no issues either. HSPA data everywhere.

883 worked fine for me on that ROM.

I'll give it a try since I have multiple slots with safestrap. Guess I'll be the first to test. I'll let you guys know how it turns out.

Works fine with the XT862 Radio. Some things I've noticed:
Not very responsive
Picking up HDSPA and 3G instead of just 3G
Only getting 1 bar of signal instead of 4
I flashed the latest build which was CM10.1. I had some problem with the recovery since I previously had clockwork recovery installed. Upon starting the phone, I had 2 force closes(Media and Phone). Once the ROM gets smoothed out and has camera working, I'll make the final switch.

HSDPA *is* 3G.
HSDPA is in the same line as UMTS, which was technically the first 3g, then HSDPA/HSUPA were developed on that technology, then HSPA, HSPA+, then dual band HSPA+ which tops at 42Mbps. They're all technically the 3g (or 3.5g if you would) standard. Albeit T-Mobile and AT&T boast their HSPA networks as '4G' cause it looks better in marketing.
The Droid 3 supports up to HSPA 14.4Mbps.
Getting 1 bar instead of 4 is normal if you haven't modified the build.prop in a stock rom, there's a line verizon had added in to make the signal look bad (although looking in status shows normal signal levels, it's just cosmetic). On a kexec rom, if your build.prop hasn't been edited correctly to have the signal fix (which is under mobile networks) it'll also be stuck at one bar instead of normal. Although, if you're somehow using the stock XT862 radio, there should be no required edits to the build.prop to get proper GSM signal bars in a Kexec rom...

Well, since you seem to be the only person ever to use the stock xt862 radio on us gsm (without proof), and do not feel compelled to share how, we cannot help. I cannot work to fix something without any knowledge of howto, considering the radio lock is in the signed radio.img, radiocomm cannot modify it, as with the d2g, the lock was in the nvitems, which can be edited. Also, the radio.img cannot be modified and flashed, as the signed keys wont match the locked bootloader and will cause brick.
So unless you can provide proof/method of using the stock xt862 radio on us gsm, sorry... My guess is you actually have the xt883 radio and your build.prop just says xt862. Sorry for stating it like this, but I can claim to use the d3 on lte, until proof and method are given, there is a very thin margin of trust.

There is some proof. I know it's hard to prove other things, but I promised not to say anything. I don't want to get anyone in trouble. I can provide more screenshots, but that is about it.

How To SIM Unlock Samsung Galaxy S4

Edited..
Since lots of ppl already reported that this method doesn't work...
I just read this post in redmondpie..

II really want to try this.. but my wife brought her S4 Sprint with her so I couldn't try this at the moment..
Maybe someone would like to try this out and report this discovery?
so here's the Link:

Be very carefully doing this on sprint S4 it may brick it cause this process only works for ATT- T-Mobile GSM phones only

I also tried it to many times with no luck I wish this worked.

Hello. Some one try to flash radio firmware from verizon sgs4(it has unlocked gsm) ? it work for nexus but vice verca

This method DOES NOT work. Sprint BLOCKS US GSM carriers. To get an international unlock you need to call sprint and ask for one. At this time there is NO way to get US GSM signal on the sprint S4.
EDIT: Apparently this will make your phone unable to connect to a femtocell. Be careful

Do not try this mod. It will mess up your phone and how it connects to the Sprint Airave.

I noticed this. Any way to revert this? Or will I have to go into sprint?

Not that I am aware of. I am trying a complete factory reset of the phone. I will post my results when I can.

Please let me know how the factory reset works out for you. My phone is officially messed up. My 3g was not working at all. I would only connect LTE. After troubleshooting forever with sprint, my 3G is working again but it is very slow. I also notice that it does not auto roam to Verizon at all.

Updated: I have rebooted the phone next to the booster and then did a firmware update, PRL Update and rebooted the phone. It appears to be connecting again.

How was the speed though? It may show "3G" but my guess is that it's really 2G speed or something on TW.

I've had massive issues with my 3g after this method. The 3g is super slow and I know something is not right. Is there an app that displays the cdma band that the phone is currently operating on? I read somewhere that it screws up the phones ability to access the cdma 850 band.

What we really need to do, is find a way to undo this. Even though my phone appears to be working. I really wish I had never tried this and could go back.

Yes I hope someone figures it out. Reflashing the stock software is not enough

Update: My phone appears to be staying connected to the Airave and getting a very good signal. Data speeds were never really affected just terrible connections. :good:

I tried this also and it messed up my 3g speeds, after much searching, reading ,and experimenting,i did a SCRTN which restored modem ,lesson learned

There is another thread that is similar to this for unlocking the sim. I tried it, and possible messed my phone up. I was getting slow 3g speeds and mobile data drop outs. I fixed my issue by doing a complete factory reset/ clearing NVRAM. This is how I did it:
Dial ##786#
Choose Reset
Enter MSL
Here is the thread I mentioned just in case one of you wants to look at it. http://forum.xda-developers.com/showthread.php?t=2282683

##786# as far as I know will restore your phone to stock .
##72786# should reset your network settings. Just make sure you are in a working 3G coverage area or have a WiFi connection or it wont re-activate. This method does not put your phone back to stock...just reactivates it on the network.

Sorry for the unusable info...
But i got this news from Sprint Htc One thread, that they are able to unlocked the device by simply rooting the phone and sending a line in terminal...
Is it possible to do this with ours?

1. You should be rooted
2. Download https://play.google.com/store/apps/details?id=jackpal.androidterm
3. Run Terminal Emulator
4. Type "su" (excluding quotation marks) and grant it superuser permission
5. Type "am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity" (excluding quotation marks)
6. You will get menu on your HTC
7. In that menu, select "API", then scroll down 'till almost end and select "simlock"
8. Reboot the phone and hopefully it would accept GSM SIM
9. Enter *#*#4636#*#* in your dialer
10.In the phone information section(the first one) set preferred network type to something that is GSM specific: "WCDMA Preferred", for example. The phone will switch to GSM mode
