US Tmo tab JJB...what are my options?!?

OK so i've had my tab for about two weeks and i can't get a clear answer as to what my options are for flashing my device. I see many JMC and JJ6 and I'm really lost. I know there are many models of this tab but i want to know for the American tmobile tab specifically.
the firmware i have says JJB...What are my options as far as to flashing to a new firmware?
Is there an official upgrade?
I will only use it for data and not voice calls, so i want to have 3G. I would like a fix to the lag in the calendar and browser.
Can any of the firmwares help me?
I also installed Kies with drivers and it doesn't see my tab? Do i have to be in download mode for Kies to see my tab?
Thank you very much for your time.

Same boat as you. awaiting some guidance as well.

Same thing here. Kies doesn't recognize my tab and I'm on JJB. Changing your IMEI works though, allowing for 3G and bypassing the T-Mobile redirect. I'm on the old school 5.99 T-zones plan and getting unlimited 3g .

same here there is very little guidance and very helpful people but I can't seem to just get a simple question answered here or there to feel comfy enough to flash my new tab, I know you want rotojme because there are no bootstraps installed. I know the koush clockwork mod kernel installs ext4 file system which is great but I can't remember where to put the files I need to adb? lol Im a mess cause its been since the g1 that I have ever adb anything.

Has anyone using JJB taken the leap of upgrading to a better firmware? How did you do it?
Any advise would be appreciated.

Seems like it is safe to flash the new roto jme rom. It.s in the development section.

JJB is possible
Happy New Year.
New roto's rom is working great. So far I flashed 6 units no problem. They were all JJB. Here is bottom line.
Current status, No voice and 3G possible.
Users have 2 options.
1. 2G(EDGE) with Voice by flasing (Euro Rom)
2. 3G only (with IMEI Mod)
I appreciate Rotohammer's hardwork for this.
If you need more detail, check out following blog at
sooparkhero.blogspot.com
It will go through step by step tutorials.

Can't wait for there to be a tutorial on how to flash a T-mo tab and get 3G. That's all I'm waiting for.

I went through the same mess with mine. I finally just flashed the full jm6 for samfirmwares.com and then just the pda piece of jmc. Since then i used rotos pre rooted jme. Again by just flashing the pda piece. The day after i flashed jm6 is wheb all this talk about different bootloaders came up, so im not sure which boat i am in but i could care less. This jme is ridiculous compared with stock tmo firmware. I am happy enough.with it for this to be the final state of my tab. Lower the lcd density a bit for a better looking tab and remove the contents of your efs folder(AFTER backing it up) for the imei mod that frees you from the webconnect plan and you are set

Issues with roms
There has been some issues with new roms. The issue is once you flash into one of these roms you can't revert back to old one. Here is related link.
http://forum.xda-developers.com/showthread.php?t=888071
Professionals recommand not to use these roms until they are modified and further tested.

i9000 with ICS problems.

Guys,
I've been using an SGS, followed by an SGS 2 and have always used custom ROMs without any issues in the past. I have recently traded the SGS 2 with a friend for my old blu-ray player and an old SGS. Long story, won't go into why.
No matter which build of ICS I am using, I am getting serious problems with this phone. SlimICS does not find a signal at all, it just says no service. On the one I am running at the moment (4.0.4 GTi9000_IMM30B_BETA_8_RC) and also with the nightly CyanogenMod builds, if I take or make a phone call, everything is fine. When I next go to make a call, the earpiece does not become active. The data and normal network connection is still active, but this renders the phone almost useless - having to reboot the phone every time I wish to make a phone call takes as long as sending an email for me!
Also, I should be able to choose Tmobile Orange as my network service as I am with T-mobile, who is partnered with Orange to give better signal. On the ROM I currently use, "Tmobile Orange" is not a selectable network.
Is this a problem I can resolve by flashing with a different modem?
If I can't fix this I will probably just run over the phone and buy a Nokia Lumia (change does wonder for a headache!)
Any help is appreciated.

Yes I've actually used the JVU one from it and I also tried using Odin to flash it manually using the modem I am able to get Tmobile Orange with at the moment on Gingerbread - neither work.
Is there a specific modem I need to use in the UK to get this reception?

Go to samfirmware and see which it is under your section. Ex my download is called something like ""XX-KG3. Which means my modem is KG3.

I am getting nothing from the Checker page when I type in the details I have.
Like I said, I know it is JVU firmware I have because I've manually flashed it and it works perfectly, but when I install SlimICS it simply does NOT pick up a signal at all, even if I flash it with a radio seperately afterwards.

No signal
I installed Slim JB yesterday and no signal at all.
I tried JPG and JPU modems from this thread http://forum.xda-developers.com/showthread.php?t=1158783 but no avail.
Still no signal. I am going to try with other sims and even other roms to asses my problem.

Is it possible to use Defy+ on Telus Mobility in Canada

Hi,
I just picked up a Defy+ from a wholesaler online. It was supposedly unlocked already but it won't work when I placed my SIM card in it. My card is for Telus Mobility in Canada. Just curious if anyone has had success using the Defy+ on Telus's network. When purchasing the phone I was under the impression that it was just a Defy with bumped OS version and higher CPU clock speed, but essentially the same hardware. Telus previously offered the original Defy so I'm assuming that the Defy+ will work also. Any help/advice/info would be greatly appreciated.
I've also got a similar post on this thread but decided to create my own as well.

Just an incompatible baseband selected. What is the rom version you have on it?

Phone is still stock as it came
Just added a screen shot of the about phone. Haven't flashed any ROMs yet, or even rooted it. I'm waiting to make sure I can use the phone with Telus before I start doing all that to it. In case I need to return it.
I was considering flashing the baseband from this thread to see if it had an effect. Do you have a suggested baseband I should flash, or a suggested thread to follow? I'm no stranger to xda and modding phones, though I'm far from an expert and the Defy+ is completely new to me so I'm still just doing a lot of reading on it before I do anything.
Thanks,
Vic

Still not luck with Telus network
So after trying various Defy root methods I discovered that the old exploits don't work on my phone which has BL7. Found a good thread that handled rooting my device and successfully rooted. Following which I installed a current 2ndinit from this thread and then flashed the latest CM10 nightly. After playing with the baseband switcher and trying everyone I still haven't gotten it to register with Telus. The best I've achieved is finding the network and it failing to register.
Anyone with suggestions on what I should try next?

Still trying to get this device to work with my telus SIM card. Looking for any help to trouble shoot. Would like to start using this device as a second phone. Any suggestions would be appreciated.

Have you manually entered or checked to see if the APN are correct after booting?

OKay I see it says you that it was supposed to be unlocked but i'm thinking maybe you should get another unlock code and try it. That would be the only other reason i could see it not working other than APN not correct or wrong baseband. Try China ME722.1.10.

Thanks for the suggestion. I'll give unlocking it another shot tonight. I tried a half dozen baseband settings in cm10 that match the telus bands but no dice. Keep getting an ME error when it did see the telus network. I'll post my efforts tonight.

I've come to the conclusion that getting the Defy+ I purchased to work on Telus isn't possible. At least by me. I confirmed that the device was indeed unlocked by trying it with SIMs from both Rogers and Fido, which both worked. I also tried a Bell card and had the same results I had with my Telus SIM, which was being able to see the network but not connect or use talk or text. This was regardless of the baseband I used.
In the end I just returned the phone back to complete stock and gave the device to a friend on Rogers who needed a new phone badly but couldn't afford an upgrade at this time.

Too late now, but for reference you could have tried flashing a new radio. Worked for me, and also the baseband that works may not necessarily be geographically related to your location. In India the Vodafone France baseband works fine
Sent from my MB526 using xda premium

I tried to flash the Telus.zip baseband I found in a thread and it returned an error on each attempt. Flashing any other baseband that matched the frequencies for my network still resulted in a failed network connection. Same results occurred with the Bell SIM I tested with, which is a very similar network to Telus. After checking Telus' compatibility list it clearly stated the Defy+ was not compatible. I still find that strange since as far as I understand it is simply a Red-lens Defy with a larger battery and a more current ROM. I thought for sure if I added the correct frequencies I'd be set. I was mistaken as my repeated attempts have shown.

Interesting. But did you flash an older or newer Radio(not baseband)?
If defy is compatible defy plus has got to be, unless they use some twisted form of imei locking
Sent from my MB526 using xda premium

I tried the baseband from this thread: http://forum.xda-developers.com/showthread.php?t=1117553
I also tried using the cm10 baseband switcher.
Didn't realize I could flash a radio as well. When I did see and connect to Telus I'd immediately get an ME error and then loose connection to the network. Where would I find radio files?

Isn't it redundant now, since you don't have the phone? Anyways there's a thread called radio fixes or something
Sent from my MB526 using xda premium

Not having the device anymore doesn't negate my desire to solve my problem. I might get that phone back or I my decide to pick up another unlocked device that gives me similar problems. I no longer want to sign contacts for discounted devices so I'm always on the look out for good deals on unlocked hardware I can play with. Thanks for the replies.
Sent from my HTC Ruby using xda app-developers app

Well since I'm on Telus as well with the red lense defy and I checked gsm arena and a few unlock sites. They all said and indicate that phone can be used on the Telus network. Seeing as its not a phone that Telus originally sold that is why I asked about the apn. Anytime I've ever used an unlocked phone on Telus I've ways had to input the apn.
Other than that sometimes when I flash I don't always get a radio signal for some strange reason. Even changing baseband doesn't solve the problem I usually have to flash another rom and then come back to the one I want or try a different kernel. Either way I'm like you except I never would have gave it away till I solved the problem lol
Sent from my MB526 using xda app-developers app

It was more than just a case of setting the apn. I have no problem doing that. In fact that's exactly what I did with the Rogers SIM so that I could test it's data before I let my friend have it. I tried numerous ROMs with it, none of them would allow me to connect to Telus even after choosing an appropriate baseband. Unfortunately because it wasn't a Telus phone to begin with I didn't have a working Telus radio on it. I tried flashing the Telus baseband, it would return an error. I tried flashing the entire Telus ROM, it went into a boot loop as expected. I got it back to it's stock Retail ROM, after rooting that tried a baseband switcher and still wasn't able to see connect to Telus. Though it would see the network. Best luck I had was with CM10 with the Argentina baseband which would connect to Telus until I either tried to call or text. At which point I would get an ME error message and it wouldn't connect again without a reboot. At that point I suspected that maybe this device was being blocked by some sort of IMEI filtering much as thekguy suggested above and gave up on it for now. When my friend does upgrade and returns the phone I might try again for kicks. It was a neat little phone. I'm even tempted to look for a used one that is from Telus...

Please shed some light in the errors you get while flashing the telus baseband
And if you get a boot loop after sbf flash, then wipe data and cache from stock recovery
Sent from my MB526 using xda premium

I'll clarify my description of boot loop in the instance of after flashing the Telus froyo stock ROM was actually more of a soft brick. The phone became unresponsive almost immediately after turning on, blank screen, no response to button presses, essentially a brick. The only sign of life was if I pulled the battery while connected to usb the LED light would flash white for a brief second. That gave me the idea to start up an sbf flash until it got to the waiting for device message, at which point I'd plug in usb and install battery and the flash would force it into boot loader before it could go "dead"again. As far as a ROM getting stuck at the boot image, yes I know a quick wipe fixes the boot issue. At least it had for me every time I got into an endless boot process. Had to do it after recovering from the failed Telus ROM flash with the stock Retail ROM.
Thanks for the tip though. I know you are being helpful.
As far as the exact wording of the error message, I'll have to look it up when I'm back at the PC I use for modding an such... Most I can remember is it start with "ME blah blah blah" but I have a note saved with the exact line.
Cheers, Vic

If the telus baseband failed to install via cwm due to cwm incompatibility, you can manually try to copy over the baseband files included in the zip according to the directory structure of the zip
Well, this was my last idea:If this doesn't work
Sent from my MB526 using xda premium

Ya, that was the one thing I wish I had tried before giving up on the phone. I'd considered it but wasn't sure if it'd work. When I passed it on it wasn't rooted anymore and I'd invested so much time with getting it back to stock that I had just had enough of it at the moment. Almost regret it. If I get it back any time soon that'll be where I start again.

Tablet doesn't look so good...

I have an SGH-T849. Trying to unlock it. Cant find any positive guides for custom roms or anything. Everything is only on the p1000 so I took my my chances and flashed p1000 firmware so I can fit in. But now I really need your help cuz network signal is a must and I lost it after the flash. I have my imei and everything is fine but the tmobile network wont register I am trying figure out how to fix this. I have tried copy and paste modem.bin to system/vendor and flashed the tmobile modem but no go.. Also I am in bad shape because I cant find stock firmware anywhere. All links are dead and samfirmware doesnt even have it listed. Any help would from anyone would be great considering this isnt my tablet

Not every Rom has modem.bin at /system/vendor
In fact most at /radio except for cm10 that was built about two weeks ago to last week.
Now all back to /radio.
And I am talking about ICS and JB Rom.
And correct apn is a must.
And JJB modem for T-Mobile

Overcome gb stock safe has T-Mobile modem. Modem thread in development subforum sticky also has it.
But let me ask you this.
What do you see as baseband in the phone info.
Because even JPZ can connect to T-Mobile just no 3g. Edge only.
If has baseband and can't connect, can't help you.
But there is a person that has stock T-Mobile froyo and can share it.
You just have to search.

Well Itried flashing the the tmobile radio but it wont stick. Everything on the tab seems fine it just wont register the network. my baseband is JPZ.
Edit: I flashed Overcome stock GB and the tmobile radio... It went good my baseband is T-Mobile. However it still wont register the network. I am staring to think that the sim card is not activated.
Edit: Thanks much for your help. I am happy to say that my friends sim got deactivated. Up till 4 am thinking I screwed something up.

It sucks isn't it when another thing cause you to troubleshoot other things.
But, if you are on T-Mobile network and only going to use data and not voice call, your JPZ modem is going to only give you EDGE (2G) speed.
To get 3G you still need to use the T-Mobile modem I mentioned.

No LTE after flashing cm 10.1

I've noticed that my phone is no longer able to connect to the LTE towers that are available to me.
I also noticed that my phone uses "1x" when LTE towers are available (so that's fun)
3g and 2g work just fine but LTE refuses to work
Here is what I've tried:
Reinstall the rom
Do a clean install of the rom
Play around with the apn and network mode
Restart my phone
Update the firmware
Update to the latest nightly
What I'm going to do:
Install the stock rom
And/or install the Google play edition rom
Any ideas why LTE isn't working? And does it work on anyone else's phone?

I remember when i would flash CM10 and any CM10 based roms on my sprint Note 2 LTE wouldnt work it was broke on CM10 based roms well any non TW roms one thing that sometimes would fix the issue is reflashing a TW rom updating prl and profile then going right to cm10 but it would lose lte after a reboot for me still.

Also try a different kernel. Works for me when I only have 3g in an LTE area
