hmmkay, so i'm looking at [GUIDE] HowTo Downgrade From OTA (INC RADIO) http://xdaforums.com/showthread.php?t=831398 & it instructs me that i will need a HeX editor. i click on that link & it just takes me to http://xdaforums.com/showthread.php?t=794053&page=39 which is a closed thread of [Thinktank] ROOTING G2 Vision T-mobile. i don't see any link there for a HeX editor.

uhhh can i just use notepad?
[G2 and Desire Z Q&A, Help & Troubleshooting] digikid:
not for hex editing. Here's a free hex editor I found. Also, make sure you can use adb from hboot before starting this lengthy process.

hoookay, i'm in HBOOT on my phone (HBOOT USB PLUG).

so how do i get ADB SHELL going?

i was fortunate enough to get the misc.img/miscnew.img files from the forum.

i'm in:

C:\android-sdk-windows\tools

i type ADB SHELL but get:

error: device not found

in a nutshell, all i need to do is execute this command:

dd if=/sdcard/miscnew.img of=/dev/block/mmcblk0p17

and i *should* be home free.

GUYS GUYS GUYS. Look no offense to anyone, but in serious situations like this, if your not 110% sure, dont post. i see several things in this thread that could make someone in a similar situation much worse off.

now that being said, OP, im sorry your in a pretty bad place, but all hope isnt lost yet. there is a few things we need to try first to determine your status, im gonna pm u my gtalk addy. if we find a fix i will post back here...

notice to everyone. once you are s-off dont flash the signed PC10IMG.zip it will lock you in what ever state you are in, ie boot looping. you must have the correct rom on your phone before using it as per the unroot thread!!!!!

[HD2 Android Q&A, Help & Troubleshooting and Genera] xguntherc:
Hey guys. Today is my first night with a HD2.. So far i love it Running Android. I'm running Darkstone's build v3. everything seems good for now.

My question is regarding loading more than one Build of Android on the HD2. Like right now I'm on Darkstone's Stock FroYo build, but my friend is running SkinnyEVO. I'd like to try that to as I've never had a Sense Device.. Can I add the skinnyEVO files to my HD2 and boot to it, then later on in the day boot to Darkstone.. or is it only 1. So if I have all my app's installed on dark, and I boot to SkinnyEVO. will it all be there, or no?

I doubt I can, but just thought I'd ask. I don't want to set everything up and then decide I wanna move to a Sense UI build and have to start over.

Thanks!
[HD2 Android Q&A, Help & Troubleshooting and Genera] secano:
Just rename the Android folder. The apps won't be transfered to the other one, but if you have the apk's you can drop them in the AndroidApps folder and they will be installed once you boot.
[HD2 Android Q&A, Help & Troubleshooting and Genera] xguntherc:
So one folder named Android is the darkstone I'm running now. AndroidEVO can be the skinny EVO version, and so on.. and I just click CLRCAD and haret in the folder I wanna boot to..

right? Thanks!
[HD2 Android Q&A, Help & Troubleshooting and Genera] xguntherc:
Can anyone recommend a HD2 Rom that has good battery Life. I'm running DarkStone's Stock FroYo build and I get terrible battery life.. Usually full battery. i work from 9:30 to 5:30 and I have around 75% or so left on my Nexus One, but today on my HD2 after working the same shift I only had 36% left.. Is it really that bad, or is it the big screen and small battery?

I'm going to try and undervolt tomorrow and see how things go.

in case it got lost at the end, we now have the US TMobile Galaxy Tab making/receiving phone calls.

Download Odin3 v1.70

to flash.

Used;

P1_20100909.pit

for formating. Selected 'Repartition' 'AutoReboot' 'fResetTime'. That rebooted with nothing apparently working but the filesystem structure was setup.

Download P1000XXJHA

for the base rom.

Then, unchecked the 'repartion' part (as the structure is setup, don't want to screw it up, the next flashing needs to 'drop in' where the structure is.

Then, loading into the JHA.rar just downloaded, flash that and reboot.

To update to latest;

download and flash;

P1000OXAJK1.tar

Pop in your SIM.

At this point, reboot. It'll probably show 'Emergency Calls only'

Went into the wireless/Mobile Settings/NetworkOperators and made sure it was connected to TMobile.

At that point, I made my first call and it worked.

Received a call too, also working.

Good luck. If there's an easier way todo this, I'm all ears as I had a few moments of 'uh oh, why's it now showing anything' but the fantastic forum posts here with people having the same problem resolved that.

Only working on Edge at this time also.

No idea how later updates will work too, so caveat emptor.

*Edit. Further adventures.

So, now having the euro stuff on to make calls, but having the issues, wanted to try a few things. Put the US Tmobile back on to get 3g but lose voice.

Firing up a call, logs showing;

Interesting the error message shows it's APN. Leads me to (wildly) guess that a new radio COULD be worked out, but also the carriers could send out an update message to allow it to work without other upgrades. If so, then there may be an 'enable switch' we can use to get it working too.

I have never been more happy with an electronics purchase than with this tab. it just works the way i expect it to in both work and play , i know sooner or later there wil be something better to replace it but for now (especialy with the addition of phone to the US ones) no other tablet comes close.

XDA you are awesome!
[Galaxy Tab General] feisley:
I have a GT-P1000 from Germany in the US.

I tried the manual band selection with the European firmware with my T-Mobile SIM and failed to connect to 3G. I tried every combination with no success.

3G for my AT&T SIM does work fine however.

ATT has different 3G band, 850 and 1900 versus T-mobile's AWS 1700/2100
[Galaxy Tab General] calin75:
I went to *#2263# menu and selected all the bands, including 850 and 1900, but still nada. Most of the time my tab losses total signal and goes into emergency only mode. I have played with the setting but no luck so far with ATT. Anything I am missing?

Now it looks like it is connected to ATT but I have zero bars and is showing a "G" for data. I know I have full strength signal here. =(

You need to manually create the access point to get 3G on a EUR ROM

This morning I flashed the European firmware and carrier unlocked my 1 day old T-Mobile Tab and its working perfect using my ATT SIM card, minus 3g of course.

[Galaxy Tab General] maxtcee:
Looks like tmobile left some phone options in as well we have emergency dialer there to as well and a couple of phone utilities

there's a whole bunch of dialing options as well also unlock fixed dialing options but its asking for a pin and it only gives you ten attempts maybe you guys that unlocked there phone could try it

looks like all the software is there call fwd auto answer and a ton more its just locked

theres even somthing called fake call and its enabled

i remember when i got the tab with contract they ask me to put a pin in

i tried the pin to unlock fix dialing but didnt work why would t mobile ask me to put a pin number in if the tab wasnt for calls
[Galaxy Tab General] rotohammer:
Please go back and edit your post to remove that number. Anyway, good news is that you dont have the bogus IMEI, now to figure out why you have an issue.

Just to clarify with the unlock hack die everyone running the unlock and euro tom now have the same imei? Or is it just different from the original in the device?
[Galaxy Tab General] rotohammer:
Are you using a Web Connect data only SIM or a SIM from a phone with voice/data capability? The word is that Tmobile is blocking the voice/data SIMs from getting Internet.
[Galaxy Tab General] bulldebeerman:
Roto can you tell me what setup your using

Sim.rom.plan
[Galaxy Tab General] rotohammer:
Current Setup:

Euro ROM

Vibrant radio.bin

AT&T SIM voice + edge internet

Tmobile SIM data only edge (3g if I put back stock radio)

Notes:

The Euro radio.bin doesnt give voice or data on AT&T, EDGE data only on Tmobile.

The Captivate radio works the same as the Vibrant one as far as I can tell.

Stock USA radio.bin gives 3g data on Tmobile, EDGE on AT&T, no voice on either.
[Galaxy Tab General] adinis78:
thanks to the help of rotohammer i flashed the Vibrant modem.bin and tried using my current Vibrant sim (voice/android data), well unfortunately it still does not work when i open the browser i am directed to the tmo site. PLEASE NOTE I WAS NOT TRYING TO GET THE PHONE OPTION TO WORK, I WANTED TO TEST IF MY CURRENT SIM WOULD ALLOW ME TO GO ONLINE AFTER UPDATING THE MODEM.BIN. Just wanted to get that out of the way. So i will be going back to the stock modem.bin and either keep using my tab via wifi or return it. No looking very good on getting this TAB to work on a regular SIM without having to get the Webconnect.....:(

if anyone out there has any more ideas on how to get the TAB to work with a regular android data SIM please do share otherwise as i stated before it is not looking good...:(
[Galaxy Tab General] xexes:
Hi roto...

anoamare over on the CDMA thread posted these thoughts about getting calling going:

"Well, first we need a recovery like clockwork for one. I was working on it but ubuntu on my pc is being stupid..

With recovery im willing to risk another tab but sense i swaped this out already im not.

The reason i think its not so easy to just swap apk's is because the whole framework + system folder needs to be resigned to work with the phone.apk.

I say this because when working on the EVO rom when i had to patch the phone.apk, i also had to sign it and sign anything that was associated with it on my pc. Or phone.apk would throw a bunch of "fc's" "

Just curious about your take on this pls? After this post he talks about once the framework is resigned then he would make a rom based on the Fascinate.

Thanks...
[Galaxy Tab General] samsci:
I just got a call from the Executive Customer Service Department. They were pretty nice, but after a long conversation and different scenarios, they pretty much said, there was no way TMobile 'could' set it up to allow voice for the Galaxy Tab. The configuration is for Data only.

So, if anyone says, TMobile can do it, they won't. Period.
[Galaxy Tab General] clubtech:
That is very interesting as the euro ROM + euro modem.bin does work will on at&t with voice and 3g on the EURO model.

I wonder why the same does not work on the T-Mobile model (with euro ROM+ euro modem.bin)...

I figure you would not get 3G but you should at least get EDGE (data+voice) to work on at&t.
[Galaxy Tab General] maxtcee:
how long does it take to swap out the modem ?

just curious cause i asked the other day if it was easy to make a modem switch
[Galaxy Tab General] ayman07:
it takes literally 30 seconds to swap a new modem.bin only problem is that u need a computer to do it. so if ur thinking of carrying both and just swapping when u need it, i dont recommend it. i wouldnt wanna keep flashing back and forth. i wonder if it can do damage to the phone in any way.
[Galaxy Tab General] maxtcee:
i doubt flashing will do any harm to your tab as i flashed hundreds of roms on plenty of phones

also note i didnt know you had to flash the modem i thought it could be done through root explorer
[Galaxy Tab General] ayman07:
yeah but u could be flashing up to 3 times a day if ur switching modem files. u flash a rom like once a week or maybe every two if ur that into it; thats what i use to do. i mean the ROM on any device shouldnt be altered that much. who knows, i could be completely wrong. but its only a matter of time before we get a tmobile/euro modem.bin hybrid.
[Galaxy Tab General] adinis78:
i flashed the vibrant modem.bin on the tab and did not work with my Vibrant voice/data plan, every time i launched the browser it took me to the tmo website, flashed back to stock modem.bin....:(
[Galaxy Tab General] rotohammer:
Its different hardware due to the different 3g frequencies T-mobile USA uses.
[Galaxy Tab General] clubtech:
But the people who flashed the euro firmware+modem on the t-mobile device were able to get EDGE data + voice on T-mobile (850Mhz/1900Mhz EDGE) so why would the same not work on at&t?

Or do i have my information all wrong here?
[Galaxy Tab General] rotohammer:
Ok, Ill elaborate. It does work, but with very low signal. Theres something odd about how it sets up the cellular radio. As soon as I flash a different one, the signal strength jumps from no bars to 5. I have a multi-band cellular repeater in my office, so its not a bad signal.

Now, since the Vibrant radio.bin didn't enable 3G, that leaves us with the /system/lib/lib*ril*.so files. They have everything to do with 3G enabling. I'm going to start swapping in the libs from the US firmware into the Euro one.

At this point, I feel phone + 3G is achievable. I'm not so sure T-mobiles proxy internet block is solvable. I've already ditched the idea of switching to T-Mobile for all my service. They can bite me!

In a nutshell, some of us will have it all. Its going to take either some libraries/software and/or a particular radio.bin.
[Galaxy Tab General] maxtcee:
so best bet is to return my tab to tmobile and gett att on black fri
[Galaxy Tab General] rotohammer:
I'm not so sure yet. I just picked up a Simple Mobile SIM locally and its working better than the AT&T SIM in that on EDGE, AT&T in my area has a 450ms latency, whereas T-Mobile (the backbone of Simple Mobile) is only 220ms. Simple Mobile is a heck of a lot cheaper than anyone else and theres no bull**** Internet blocking going on. I think it may be the only winner in the short run.
[Galaxy Tab General] maxtcee:
Well that's good news

Success with imei

Hi guys

Hope somebody might benefit from my experience and avoid stupidity.

After my attempt to do network unlock screwing the nv_data I've lost my original serial number as well as imei. This is a big deal because it is identification number of the phone that should be protected to avoid identity theft.

Luckily I saved a copy of nv_data.bin of SD card before screwing around.

My limited research showed that without such copy I would have only one choice to ask Samsung for repair or live with Wifi tablet.

I made a call to their technical support and tried honestly describe my problem. You will love this - the lady told me that I need to call Microsoft and was going to give a phone number. I stopped there :-).

Today I did research of my Vibrant (younger Galaxy brother) and discovered that there is no way I can generate md5 hash for my nv_data. Samsung is using something else in addition to the .bin file. I also found product code for T-mobile US, that is TMB.

This code should be in two places

@ offset 0x18800F was SER changed to TMB

@ offset 0x188021 was SER changed to TMB

Then I

- saved modified nv_data.bin to sd card,

- using root explorer copied it to efs/ directory

- deleted md5 file existed in that directory

- rebooted.

Now everything came back. T-mobile recognizes me as legitimate customer.

Conclusions: don't trust everything is said on forums and do your own research or be prepared to suffer.

Although this is not a complete picture you can get a point.

Cheers!
[Galaxy Tab General] rotohammer:
Very interesting. Could you describe which technique you used that trashed the nv_data.bin file? We want folks to stay away from that. I just got word that my technique just worked for someone else, without trashing the IMEI or serial number.

Regardless, the process is totally reversible if you backup your files first.

Also, the carrier code in my original nv_data.bin is set to KOR, which I assume means KORea.
[Galaxy Tab General] jtc442:
unlock success

I just unlocked my TMOUS tab with the help from roto. My first attempt didnt work. But I tried a second time, and after I did it, I inserted an old old sim from cingular, and it booted up without any issues. I checked my IMEI and my S/N, and all is well. Now I cant wait to see what comes next!!
[Galaxy Tab General] calin75:
Interesting, but you didn't tell us whether it surfs and/or makes phone calls.
[Galaxy Tab General] jtc442:
Well, unfortunately, that sim is 7 years old and hasnt been active in the last 4 of those 7, so I couldnt test those functions. But, my first attempt failed and just showed me the enter sim unlock code. I tried again, went right through. I will test an active sim tomorrow at work and let you know what happens.
[Galaxy Tab General] Adapt0r:
Thank you Rotohammer for providing your advice

You are absolutely right backup is our best friend.

Usually, I do backup and save everything in a safe place but this time was not careful.

I did it but because the process was very messy I lost track of things.

Instead of describing my mess I would simply recommend to stay away from using unknown software that promise to do a magic on your hardware. I did unlock on Vibrant manually finding the unlock code that was there explicitely. It worked without a glitch.

I just providing pieces of information since we cannot access better info.
[Galaxy Tab General] rotohammer:
I'm new to Samsung phones, and I tried using several software packages for other phones, but after I trashed my files, I found that Samsung changed the format of the nv_data.bin file, so none of the old softwares would work now.

But, the cool thing is, once I figured it out, its actually pretty easy to do (for me anyways).
[Galaxy Tab General] Adapt0r:
Well Vibrant is my first Samsung phone. I had several iphones, G1, my touch 3g and some others.

Samsung is behind in software and GPS on Vibrant was horrific. BTW tab with original firmware had GPS working only with Maps. Suprisingly it works extremly well on EUR firmware.

Cheers
[Galaxy Tab General] jay_jay_n:
So by doing the unlock method do u all have the same imei? I want to take the plundge since skype lag is really annoying.

So the steps would be unlock then euro rom right?

To get edge with phone capabilities on Tmobile tab
