Flashing T-mobile tab from Euro firmware to stock.

So I flashed my T-mobile tab to the Euro firmware,everything went smoothly no problems. I got the phone portion to work, I was able to make and receive calls but the one thing that does not work is the data portion. I am using my T-mobile Vibrant sim which has voice/android data on it and as stated everytime I try to go online it takes me directly to the T-mobile site. Obviously this set up doesn't work for me unless I can get both data and voice on the tab using my Vibrant sim. So is there a way to flash my tab back to stock or am I stuck using the Euro version?

I'm working on how to do that right now. I'm trying to restore the filesystem from a dump using odin, but its tricky . the radio is easy.

Why was it so easy to get att stock firmware but not t-mobile

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.

Professionals recommand not to use these roms until they are modified and further tested.

Samsung warranty after root/recovery/ROM?

After installing CWM recovery, kernel, root, and CM7 on a Vzw Tab, is it possible to fully restore it back to stock so that Samsung will honor the warranty?
Friend of mine's Tab is having some screen issues and the warranty expires in about two weeks.
Is it possible or is he SOL?
Thanks

Yes he can. There is a stock ROM EC02 that is flashable using a program called Heimdall. It takes you back so Verizon would never know.

Sweet! Thank you much.
I saw some posts about stock ROMs floating around, but wasn't sure that the kernel, recovery, and EXT4 could all be restored back to stock.

I have an AT&T Galaxy Tab and that link doesn't work for me. I've tried everything I possibly could to try to get this thing back to something I can use that doesn't reboot when I try to use the keyboard. I've done search after search and it never provides me with any information that's helpful to getting it back to a workable condition. I've come across the link above numerous times and I've tried to use those instructions over and over with no success.
I really think it's worth pointing out that constantly pointing people to these directions isn't helpful to those trying to restore a non-Verizon Tab. It's done zero good to me with my AT&T Tab.

But I clearly asked about a Verizon Tab and he replied with Verizon Tab-related info. That's a helpful thing.
On the other issue, the last thing you want to do with an AT&T Tab is try and use CDMA (Verizon/Sprint) ROMs. This is probably why your Tab is screwed.
Stick to GSM/ATT ROMs and you'll probably have better luck.

I've tried to find AT&T ROMs and none have worked so far.
Every time I search on this subject here I get sent to the Verizon fix.

I had the same problem, for some reason the older versions of Android that was posted on here haven't worked for me. Pretty much all the links provided in the instruction posts on turning the tab into a phone had Froyo 2.2 links. However I downloaded the Gingerbread rom 2.3.3 and flashed it and it works now:

Don't forget to reflash the radio you want.

Verizon rom ok to run on sprint tabs?

Verizon rom is newer 2.3.5. And I need some of the functionality of it. I am tempted to download one of the rooted verizon roms. But do not want to brick my tab in the process. Can anybody confirm that verizon roms can safely be used on sprint tabs?

the actual fully stock VZW rom would probably try and flash a modem update, and that wouldn't work on the sprint tab (and could be catastrophic) but any of the custom VZW roms should work fine other than possible loss of 3g functionality.

I'm about 99% sure you are correct. I plan on running a Sprint tab this way (wifi only) and will have a definite answer for you in a week or so, but someone will have already answered you for sure by then.

Verizon data

Can someone try this zip for Verizon on that you can not get data on? I am not on Verizon but just trying to help out. This has to flahsed with a clean flash and at the same time as you flash the ROM. So flash ROM ....gapps.....data zip and then whatever else you want. Hope it works. Its just a stock apns_conf.XML from stock Verizon and made it into a zip. Real simple but hope it works.

Thank you for this. I've been running stock happily because of the reports of data issues on cm12 based roms. Aosp rom that I've tried worked fine. I don't want to chance messing things up having to flash the factory image to get data back honestly or I'd give it a shot right away. Downloaded it just in case people report good results.

Really, I am nowhere near a dev. Just a real possible simple fix converted into a flashable. I am on sprint and sprint data is a son of a gun. Sprint fix is the same file but with sprint apns. And I was just thinking that it would work for Verizon with the Verizon apns. Just trying to help.

Appreciate that. Especially since you're not even on Verizon. It's hard alot of times to find people that want to help especially when its not their problem on their device. So I applaud the effort. If I get a chance and feel like a risk-taker I'll try it lol. If not when I see someone mention the data issue again I'll direct them to your thread.

Tried on cm12 and it did not work. Thanks for the attempt though.

So sorry. Sprints fix is that simple. Just flashes the stock sprint apns and whalla ......i thought the same principle would work. Some sent me the Verizon apns file and I put it in a zip.....dam. Well there will be a dev that figures it out for you guys. Got love you all.
