Radios: t989, t989D and i727 ?

Hello,
I have recently flashed TDJ's Darkside Beta2 ROM, and as a prerequisite, I had to upgrade to an ICS modem. The one I tried was UVLC8 ICS RADIO and this seemed to work great until I noticed that I never got a 4G icon for packet data, only 3G. Scanning the thread revealed that people don't have an issue with getting a 4g icon. Further testing revealed that my speed gets capped out at 11Mb/s So I am assuming this radio is really stuck at 3g speeds. Enabling GSM only also doesn't work, I can only use WCDMA only (or auto).
Now this modem and ROM are specifically for the tmobile t989 but I actually have the Telus T989D, and up until recently, I always assumed that the hardware was 100% the same. I read up a little more and found that Telus uses a dual-band for GSM, does anyone know what this is and if Tmobile's network is the same? I am assuming this is preventing 4g speeds.
What I would really like is to use the old KJ8 modem that came with the telus phone, but I think its RIL is incompatible with ICS.. Don't know if Roms flash over this RIL but the modem flash certainly puts one in place.
The only other modem available for ICS is the one from the i727.. I am assuming that trying this is a bad idea? I heard you can easily brick your phone while flashing radios.
Can anyone else make a suggestion on what I can do ? Am I stuck at 3g until someone leaks the Telus modem ?

try using the KJ3 radio that is in the NexusMOD thread.. it's a telus radio and i'm pretty sure it works on ICS

Isn't that a rather risky thing to do... ?

and thats the thrill of flashing i love the feeling after you installed the rom you will be holding your breath hoping it will boot up. lol

Just use the one from the nexusmod thread, because it has the system folder removed. You do not want to flash over the ICS RIL files or it will break signal
altogether.

Same problem here
I'm on T-mobile, and flashed several ICS roms before flashing Darkside Evolution Beta03. As described in the OP, I flashed the UCLV8 radio. Since then, my signal has not been as good as it was before I flashed the new radio. I tried flashing the UVKL1 radio a couple of times, but I had no signal. I flashed cache.wipe and reflashed the UVKL1 radio and still no signal. Next, I tried the Blaze 4G for ICS radio, and phone signal is better, but my data connections are timing out.

Thanks for the file. I see what you meant about the system files that you removed. I ended up restoring a backup from the Malice GB ROM because my ICS backup had a bad MD5 checksum. Maybe this weekend, I'll give it another go.

Custom rom removed service.

When I installed 1.35 liquid on my Galaxy Nexus I could no longer get 3g, 4g, or even make phone calls. In settings it says no service. Is there some step that I just didn't follow. Also when I reinstalled stock the service came back.

since you mentioned 4g, i assume you're on verizon?
did you update the radios to handle the 4.0.4 rom?

[Q] Can't Connect to Mobile Network after Custom ROM Flash

Hi all, so I'm in quite the predicament. I can't seem to reestablish a mobile connection via Verizon at all since I've overwritten the stock ROM with Cyanogen. I have Inc2, now loaded with CM7, awaiting some help.
First I unlocked the bootloader and flashed CWM Recovery.
Next I flashed Build 4 CM10 http://forum.xda-developers.com/showthread.php?t=1934288 <--check it out here.
I couldn't establish any network connection whatsoever. So i wiped and flashed CM9 with the hopes it would be more stable. http://forum.xda-developers.com/showthread.php?t=1932573 <--again check that one out.
Again, no network connection. Lastly, I reverted to CM7 (because it was the last stable release directly from Cyanogen). http://wiki.cyanogenmod.org/index.php?title=Vivow_Info <--looky here.
I've searched far and wide, trying everything possible. From simply switching on/off airplane mode to manually typing in the Verizon APN. I just can't establish network connection now...and the kicker - I forgot to backup the stock ROM so I'm currently stuck. Please help
This thread may be of some help. Didn't do me much justice however. http://forum.xda-developers.com/showthread.php?t=1691017

Have you tried changing your mobile network? Settings > more> network mode

Been there. You can try different radios from here, but BE CAREFUL. Take the following precautions:
Because you're on Verizon, only download 'x.x.01.xxxx' radios.
After putting the ZIP file on the SD card, verify the MD5 hash to ensure the file didn't get corrupted during download or during transfer to the SD card.
Plug the phone into your charger before installing. You don't want it shutting off during install.
Don't flash the same radio that your phone already has installed.
If all else fails, try the stock 2.3.3 RUU from HTC. If you can find a working download link to that, please share.

I've tried everything in the books. Manually setting my APN according to the Verizon settings. Also did trial and error booting and rebooting each network type to no avail.
A few things I noticed in the CM9 ROM (maybe bugs?):
The preferred network mode typically defaults to GSM/WCDMA upon reboot
The APN I create often disappear upon reboot.
Mobile Networks>Network Operators will either search endlessly or sometimes find both AT&T and T-Mobile as options, both of which won't actually connect as I have a Verizon SIM.
And in response to Slinkwyde:
To verify the MD5 hash, what needs to be done more specifically? (I'm learning as I go ) Did flashing a radio do the fix for you? I'll try this suggestion and post results.

Yes, flashing a radio worked for me. The simplest way would be to use an MD5 checker app. Use the app to make sure the file on your SD card matches the MD5 value given in the radio thread I linked to.
One more precaution: Don't ever flash the same radio version that your phone is already using. That caused problems with the original Incredible and might also cause problems with the Incredible 2. To see what radio version you have, go to Settings and look around in About phone, Phone info, or something to that effect. "Baseband" is another word for radio.

Short version: For Verizon, you want CDMA with EvDO.
Longer overview: CDMA vs GSM, and what it means for the Incredible 2
Verizon Wireless and Sprint use CDMA. AT&T and T-Mobile use GSM. CDMA is popular in the United States, but around the world GSM is far more common. All GSM phones use SIM cards, but most CDMA phones don't. The two kinds of CDMA phones that do have SIM cards are world phones (phones with both CDMA and GSM) and LTE phones (faster data speeds).
The Incredible 2 is a world phone (without LTE) and comes with a Vodafone SIM for overseas travel. This Vodafone SIM also has Verizon Wireless branding on it. The Verizon Wireless company is jointly owned by Verizon and Vodafone, a European carrier based in the UK. Verizon world phones have to be unlocked to use AT&T or T-Mobile, because Verizon doesn't want their customers switching to a competitor.
SIM cards make it easy for GSM users (not you) to use their carrier account in another phone. They can just swap the SIM. For CDMA carriers (such as Verizon), swapping service to a different phone requires contacting the carrier.

Okay so what you both are suggesting are to just install the firmware, assuming I am already running the CM9 ROM? Because the firmware includes the radio. And this is done by renaming the firmware to PG32IMG and flashing it through hboot? Would this be an easier course of action than installing a radio alone? My phone is S-ON and if I'm correct, S-OFF needs to be active to install a radio.

Yes, you can install the firmware to get the radio, and the file name needs to be PG32IMG.zip for hboot. S-OFF is generally required for this sort of thing, yes.

Also, I may have a potential reason as to why I'm having this ***** of a problem. I originally unlocked bootloader using the HTCdev tool. At the time it was my understanding that the process did not matter as long as the results were the same. However it seems now that using their tool makes it so you can't flash radios and need to extract and separately flash ROM kernels. So does this mean flashing any of the CM ROM's I tried never included the radio portion?
Just stabbing at ideas. Feel free to verify/call me out.

Roms NEVER include a radio, its always separate. something weird has happened to you, I'm sure flashing new radio would fix it for you but you're dev unlocked which is gay Lol. When you flashed the cyanogen ROMs did you pull kernel and flash like you were supposed to, if not i can't believe you got it to boot but that may be a problem also.

If it helps, here is the process that I have used every time I flash anew ROM, working every time (excluding the radio of course.http://www.youtube.com/watch?v=ujFWZbgj6bY
Because I HAD (I actually just reverted back and am currently getting S-OFF to flash a radio) the HTCdev unlock, I manually booted the boot.img after entering recovery and wiping/formatting all the necessary things. Skimming the video might give you a better idea.
However I'm now hoping S-OFF will allow me to reroot, flash CWM, CM9, and of course a radio. Currently in the process of trying to run Revolutionary.

[Q] Note 2 does not work ATT To T-mobile, wife's iPhone 5 works fine

Hi,
I have note 2 from AT&T at 4.1.1 with I317UCALJ2 and I took t-mobile connection, I can not have mobile hotspot on. Also I get call drops and less 4G connection as compared with my wife's iPhone 5, she is having consistant 4G and mobile hotspot. I called t-mobile they changed my APN settings to fast-t-mobile.com, but it did not work much, then I was reading a forum and I dialed *#2263# and selected WCDMA ALL (when I did that my APN in the settings changed back to epc.tmobile.com). Now I am getting 4G band but still no mobile hotspot.
My phone is unlocked, I unlocked my phone using the key combinations posted in this forum last year. What should I do to make my phone more usable?
Thanks

No rom yet....
Since you are changing carriers entirely...have you cleaned the device to make sure no bad data is present ??
I would suggest doing a factory reset to clean the device....
Then enter in the T-Mobile APN again and test...
If the process does not help ...a new or different modem may be needed to improve your signal...
All of the steps to do this are in the general and development sections...and you should begin by searching and reading the steps....
Go slowly...until you understand the process...and only then should you attempt any flashing....
We will be here to help....but you need to learn the process if you intend to flash files to this device...
Start in the "everything" thread in the general section....
It covers the basics of root and flash procedure...and how to avoid mistakes that catch several people...
And do not update your device via OTA...
It will give you a Knox bootloader...and that is not good for users...especially new users to flashing...
Read much....learn much...and only then should you flash....g

are you seeing LTE signal? if not, then you are on T mobile's legacy 3g or possibly the reformed 1900 hspa. Since the phone will not get 42mbps hspa, your speed maybe a bit lower due to 21mbps hspa. I am using the phone on t mobile network and do not have issue. i did have the latest att modem. When I was on the 4.1 rome, I did flashed the latest modem before the 4.3 rome.

factory reset should not change your unlock. The phone should stay as SIM unlocked (if that is what you meant). Once it is sim unlocked, it will stay as unlocked. It should not affect your root either as factory reset (though I am not 100% sure since I have custom rom so cannot remember if stock rom will remove root). Often it is best to stay with the same modem as the rom version. Here is the link to the modem list: http://forum.xda-developers.com/showthread.php?t=1987541
I have the latest one but I am using 4.3 rom. I cannot recall which modem I had when I had 4.1.2 rom so do a bit search, but I think it is the MJ4.

Thanks for the reply. I was concerned about bootloaders etc and didn't want to mess my phone up too badly. I was hoping someone would know what actual ROM would work with my specific modem/bootloader, since I think AT&T is much more locked up than TMO is.

As long as the ONLY things being flashed are the system and kernel, everything should work fine. You may have some minor connectivity issues, but I kind of doubt it since youre using it on T-Mobile's networks. Still, it is a possibility.
Anyway, just mske sure you never flash any base (or full) firmware or modem that is not specifically for the I747. Flashing the T-Mobile modem most likely just wont work (as opposed to bricking), but flashing T-Mobile firmware will almost certainly hard brick it.
Depending on the rom, you may need a d2tmo recovery. You probably wont run into that problem, but it is a possibility. It should be completely safe to flash the d2tmo TWRP or CWM recoveries if required though.
let me know if you have any other questions. also let us know whether or not wifi calling ends up working. Good luck!

Errors in Odin or recovery? Either way it would help if you could state them

And are you talking about touchwiz or cm/aosp roms?

I'm sorry, its been awhile since I've been on here. In recovery. It usually says error in sd card/ ...error 7. And also I can't seem to find a flashable boot loader. But besides that I can even get kk to flash period...thanks again

If you are trying to flash Touchwiz it wont work unless you Odin flash the 4.3 firmware

Usually cm...but the flash will give you an error and will abort installation because a bottloader isn't there...?...its not that my phone won't boot, I mean as soon as I flash it it will say opening package/installation...Then say something to the effect of error:/sdcard blah blah blah (error 7)...then say FAILED...

If its a Status 7 error it means you dont have a bootloader matching what they wrote into the updater-script. With CM it means its either too old, or too new. They dont update their scripts so when new firmware comes out it will no longer flash, regardless of whether or not it will work ok.
Try searching the rom thread to see if anyone ever posted one with a fixed script.
Or you can edit the asserts yourself.
