Ok it's late and I just got off an 11 hour day...so here is the quick and dirty version.

Your phone must already be SIM unlocked via 8 digit unlock code from VZW or third party service. THIS DOES NOT UNLOCK THE DEVICE FOR NON VZW SIM CARDS!

Be sure you have the latest Moto USB drivers loaded for either Win7 or XP SP3.

Use RSD Lite 5.0 or newer and RadioComm 11.x.x versions will run on either OS.

Google is your friend...links will be provided when I make the full writeup.

Remove any SIM and flash back to 2.4.29 with RSD Lite using the SBF available on the web.

Follow instructions in the screenshot below to edit SEEM 2042 record 0001 offset 0000 length 005E to change the first byte from default 0C to 00 and write back entire string with length 5E. Only the first byte is changed.

Reboot and then insert SIM and set it to GSM/UMTS only and you are done!

The phone should auto provision the Operator and APN from the SIM.

Edit: Here is a link to RadioComm 11.11.10 which will work well for this procedure.

[Droid 2 Global General] kyanox:
Well that explains why I was having so much trouble. I was using Seem to perform my edits. Thanks cellzealot for the quick an dirty. I'll try this and report back.
[Droid 2 Global General] jbroderick:
Thank you for this info, i will be trying it soon. I have some questions.

Can the radio ROM just be flashed separately. I.e. Can I have android 2.3.5 running an older radio or does that break compatability.

Could a newer radio be changed, is it just a matter of finding the right hex data, or is there some other magictry at work?
[Droid 2 Global General] aceoyame:
Thanks a TON cell and the rest of TBH!

I tested it and it does indeed work. I used a I wireless SIM. As for running custom roms afterwards yes you can! You just need to remember that if you SBF you have to run the changes again. I am currently running my MIUI rom with this hack.
[Droid 2 Global General] cellzealot:
Yes, it works very well as long as you stay on the original release.

When we put up the rest of the files and docs we have it will allow further research into isolating and transferring this to other firmware versions and radios.

They were required by VZW to move it out of the NVM and make it more inaccessible after the initial implementation. With a locked bootloader I am not very optimistic, but I really am curious to see what some of the bright folks here on xda and elsewhere can do with these files.
[Droid 2 Global General] kyanox:
That worked beautifully. Now the phone is trying to force a system update when connected to data. Any way to turn that off?

Edit: I used titanium backup to prevent the updater from doing anything. Then I followed the : Droid 2 Global ROOT, CUSTOM RECOVERY & SIM UNLOCK Tutorial to root / install clockwork mod. Then installed MIUI and wow this phone is reborn, plus it's now open to all US carriers.

MANY MANY thanks cellzealot and tbh, your team is amazing. Did you guys find the answer by trial and error?
[Droid 2 Global General] cellzealot:
No...it wasn't trial and error...the history of this hack is rather complicated, so we'll just say it came from inside Motorola.
[Droid 2 Global General] huukhai:
I tried and it did not work. i don't have VZW SIM, when I insert my SIM, it requested active but i don't have code 8 digit too. Do you have any way to solute this problem??? :confused:
[Droid 2 Global General] aceoyame:
I cant seem to sbf back after running the hack. What do I need to do to run a sbf after you do this? I had it working and then I was testing a change to my MIUI build and I needed to SBF except now with .29 it cant initialize and with .330 it says waiting for other devices to finish flashing and it never does.
[Droid 2 Global General] cellzealot:
There is nothing about this hack that has any effect on flashing an SBF and I have flashed my own devices, both stock and engineering models, numerous times after performing this with all versions I have seen. You have some other issue with drivers or PC config I think.
[Droid 2 Global General] aceoyame:
Weird, maybe my flashing setup on my laptop got borked. Going to try it on my desktop which I havent touched any flashing stuff on it in months. Should work on there unless I do have an issue caused by a radio hack I tried earlier. It was here
[Droid 2 Global General] ngocha2006:
Send aceoyame..!

This fails on the version MIUI for d2g.

CM7 not error.

It is bug.
[Droid 2 Global General] aceoyame:
I was testing a change I was trying out to EGL for the egl issue and of course I borked my display requiring a sbf to fix it. I have SBF'd with MIUI plenty of times before (believe me, this has been the most finnicky rom i've ever made). It is probably like cell said, an issue with my setup. Gotta find my wife's d2g because my battery is dead in mine and try it on my desktop. Will get back to you guys.
[Droid 2 Global General] aceoyame:
Well I got my phone working again. What I did was delete my SBF file and then extract it to the root of my C drive and then tried to sbf and it worked flawlessly. I read somewhere it may not like spaces in the folder path. It couldve been my sbf file was damaged too. Either way its working just fine again.

Once again thanks for the response cell. I had no idea what it could have been until you said that it was probably just my flashing set up.
[Droid 2 Global General] RWALEY:
I have been using this Hack with Fission and stock ROM for about 8 months now. Just wondering if anyone has had good success with Hexen or CM7? Fission is starting to do some weird things.
[Droid 2 Global General] bhojo1:
Thanks Cellzeolot. I am in India so can't test it but I did manage to change the NVRAM without having to revert to stock( i am on fission) so far the phone is not borked... Have to see if it works next time I am in the US :).
[Droid 2 Global General] aceoyame:
It does work fine with CM7 and any other rom as they modify just /system/ and not the radio like an SBF file does. I have tested it in CM7 and MIUI with an I wireless sim card. I have dev'd the GSM support for both rom (I even made the MIUI port) and tested the GSM successfully.
[Droid 2 Global General] kshah:
Hack shown by cellzealot is not working for me. In any rom, I get data/ length error in radiocomm. I do not need that hack though but just experimenting. :-(
[Droid 2 Global General] cellzealot:
Try bytes length 80 or even 00 which will read the seem at its default length.

005E was the length designated by the MOTO engineer who wrote the firmware and this work around, so he ought to know... ;)

You are only editing the first byte but the seem elements need to be written at their full length in RadioComm. It is more finnicky than some other NV editing tools and has many checks and failsafes built in to prevent errors.
[Droid 2 Global General] RWALEY:
Thanks for the input. I will try it out when I have a chance.
[Droid 2 Global General] anti-up:
Thanks worked great! Also for anybody wondering, the phone needs to be in pc mode....
[Droid 2 Global General] hgrimberg:
Is it the same if we are in the 2.4.29 stock rom but rooted? Or do we have to be unrooted to do all this procedure?
[Droid 2 Global General] jimi5:
Confirmed working with Fission. I did a nandroid backup of my Fission install, SBF'd back to stock, followed the instructions for the radio unlock and then restored my nandroid backup of Fission. Running on ATT now and made a few calls this AM, SMS working too. Haven't tried data as the SIM I'm using doesn't have a data plan on it.
[Droid 2 Global General] cellzealot:
As shown by others in this thread, the system version you are running and therefore root status has no effect on this hack at all. It is all in the radio NVM.
[Droid 2 Global General] hgrimberg:
Will it be possible to apply this procedure on the new leaked Gingerbread?
[Droid 2 Global General] zongsheng:
I do right follow your instructions and succeed to write SEEM. but it's not work . it's still need unlock code . i'm living vietnam, maybe your guide only use for US band ???
[Droid 2 Global General] kshah:
Cellzealot already said that it will not unlock SIM.
[Droid 2 Global General] zongsheng:
that's mean this way just useful for anyone living US? unlock band for US ???
[Droid 2 Global General] cellzealot:
Yes, that is correct. As I said in my original post describing the hack, this is just for band unlocking US GSM bands for use on ATT and T-Mobile and a couple other smaller carriers.

You must have your phone SIM unlocked first.
[Droid 2 Global General] kyanox:
From what I've read, the newer firmware from Verizon shuts down the radio. However you could try this and see, although I've noticed that essentially if you use MIUI or another custom rom, the phone is a lot better than any of the stock firmware. But i'd give it a try and report back.

I have a Question for cellzealot, is it possible to extract a modified radio firmware, then flash it onto a upgraded rom?
[Droid 2 Global General] cellzealot:
Yes we are working on that as well as an update.zip installation for this hack and other NV based hacks. This can also be rendered as a flex file or an .NVM SEEM table to be run in RadioComm.

There are many methods for manipulating the NV and applying the principles of this hack in other ways.
[Droid 2 Global General] kyanox:
That's what I was thinking. BTW i learned a lot from the quick and dirty. I suggust people try different things and see what they come up with. If you get stuck you can always sbl back to factory.

Any way to crack open the bootloader yet for custom rom support, this phone is awesome and should have community support.
[Droid 2 Global General] cellzealot:
There is no way to crack the bootloader...

On a brighter note, we just got the nv_updater binary to work for this hack in update.zip form! ;)
[Droid 2 Global General] hgrimberg:
If you perform this hack on froyo 2.4.29, will it remain unlocked for att also if you upgrade to the new leaked gingerbread? Every time you sbf, it desapears?
[Droid 2 Global General] jimi5:
I'm wondering the same thing. That release has radio update in the SBF, so not sure if there is a way around that now...
[Droid 2 Global General] cellzealot:
http://www.mydroidworld.com/forums/...-pro-update-zip-public-release.html#post98026

Here is the new update.zip version for anyone having issues with RadioComm or was afraid to try this. :cool:
[Droid 2 Global General] hgrimberg:
Did somebody notice a decrease in the GSM signal strength after applying this hack? Could this be possible?
[Droid 2 Global General] kshah:
This is indeed a great innovation
[Droid 2 Global General] cellzealot:
Yes it is...and it can be adapted to many other uses very readily, very powerful tool.
[Droid 2 Global General] skinote:
Is this the thread to keep an eye on for the carrier unlock on the new GB leak, or is there a primary thread elsewhere? I noticed a link to a different forum, so thought I'd ask!
[Droid 2 Global General] cellzealot:
If/when we get a solution for GB I will likely create another thread for that because it will involve a different method and require reverting the radio to the older unlockable version.

Until then this would be the thread to watch.
[Droid 2 Global General] hgrimberg:
I didn't quite get it. So, are you saying that after installing the leaked gingerbread on the D2G, this radiocomm hack goes away and the phone wont work on the AT&T network anymore?
[Droid 2 Global General] cellzealot:
Yes the leaked GB update.zip includes a new radio that does not have a band unlock solution available. So, if it is possible to run the older radio under the GB system/boot images then that will be the solution. That may or may not work on stock secured hardware...we have to figure that out! ;)
[Droid 2 Global General] hgrimberg:
But we can't use another radio on the new leaked gingerbread because the bootloader is still locked, right? So the hack was applied to the old 2.4.29 radio and now after installing the new gb, it went away, right? Thank you
[Droid 2 Global General] MeNaCe2s0cieTy:
So does AT&T 3G work??????????????
[Droid 2 Global General] cellzealot:
Yes...it does.
[Droid 2 Global General] MeNaCe2s0cieTy:
Hhmmmm so just a thought. Could this wonderful solution work on a Droid 3 seeing they are both only locked on U.S. 3G bands??
[Droid 2 Global General] cellzealot:
No...it can't.
[Droid 2 Global General] kyanox:
I've discovered that this hack works on custom roms, and as you know custom roms can be based on official or unofficial sources. Specifically this hack works with the latest MIUI, and well, MIUI has been way better than gingerbread. I'm guessing a developer could build a gingerbread build to work on this phone without upgrading the radio, but why would you want too? Unless they do some really sweet upgrades, I'd say the phone works like a dream with MIUI.
[Droid 2 Global General] IslesFan:
Which miui build are you running?
[Droid 2 Global General] OzzySchoonover:
My 2 cents

Hey guys, I just wanted to throw in my 2 cents in case they mean anything. I have a droid 2 global and I have recently had stock gingerbread installed. That was before I tried this. I just went back to froyo and after rooting tried your update zip and it worked without any problem. I only post this because I saw you wrote something about stock gingy messing it up, it seems to work for me, unless the sbf back to froyo re-updated the rf firmware to the hackable version. If any of that makes sense? :confused: I've been up for like 26 hours :D Hope this is helpful :) So to make it short I installed the new gingy (stock), went to froyo, rooted, and this worked without any problem, still working on getting it unlocked for the att sim, but it can see att 3g now as an option.
[Droid 2 Global General] vinvam:
Any updates on using GB with the old radio (AT&T unlocked)?
[Droid 2 Global General] Exaxoid:
works perfect

i using my motorola droid 2 global on t-mobile

its is

rooted

update

on rom

hexen-d2g-1.0.1

everything works perfect
[Droid 2 Global General] trips11:
I rooted Droid 2 Global too and loving it on T-Mobile.

The only problem is Battery doesn't last for more then 6 hrs. Any pointers to that
[Droid 2 Global General] leobg:
Old 2.4.29 firmware is a bit tough on the battery. You're stuck on it due to band unlock not working on newer firmwares.

Try the following: make sure you are in GSM/UMTS mode and not global, since you won't get 3G on T-Mo, disable 3G - set phone to connect to 2G networks only. I am pretty sure you will make it throughout the day if you don't constantly play with the phone. 2 hours and over display on is considered above average use and will significantly shorten your battery life.

Edit: go grab extended battery while its on sale 20 bucks works wonders (almost 30% better battery life in real life)
[Droid 2 Global General] MeNaCe2s0cieTy:
Does anybody know if I can buy a Droid 2 global with a bad ESN and then use this hack?
[Droid 2 Global General] tennyleaz:
I'm using on TMobile too. My battery lasts about 17 hours, but i think it is to short though, compared to my DEFY.

I will try the extended battery to see if better.
[Droid 2 Global General] kapilthio:
Tried this on Droid Pro with Verizon 4.6.4 with Radiocomm 11.11.07 on Win 7.

Rebooted. Did this again & the value remains un-changed. So does this means it works on GB ??
[Droid 2 Global General] cellzealot:
No the data in that seem is not used in later builds. The band lock was moved into the radio image and is not accessible in the NVM.
[Droid 2 Global General] JayXL14:
Thank you Cellzealot and TBH for this hack! I don't have a D2G yet but picking one up soon!

Does anyone mind telling me the best ROM that the D2G has that works WITH the baseband unlock?

Any luck with this? I have heard the Hexen one works.

[Droid 2 Global General] :
I just made the mistake of updating my Droid 2 Global to Gingerbread and I lost AT&T.

I had to go back to Froyo and implement the Radio hack in order to unlock the bands.

Does anyone know of any solution for GB with radio fix for AT&T?

Edit:

I found this after I went back to 2.2.

Can anyone on AT&T test this on GB if this will make radio work on AT&T please?

Dial *#*#info#*#*

Select PHONE INFORMATION"

TURN OFF RADIO

MENU -> SELECT RADIO BAND -> YOU WILL GET OPTION USA BAND

TURN ON RADIO

REBOOT

Thank you!
[Droid 2 Global General] Poryhack:
Why not try it yourself? All of the rest of us on AT&T are running froyo as well. I doubt this will work. It seems pretty unlikely that they'd put in a software off switch after going to so much trouble for people not to do it.
[Droid 2 Global General] :
If that is the case then why would Apple release iPhone for AT&T and put a switch in there just in case if they want to unblock it for other carriers? I have no idea what you are pissed about but it was just a question.

I know a guy who bought it directly from Motorola and he never had to do all this crap and used it on T-Mobile.

If you are not sure, ask...that is what I did. Asked if anyone tried it.

I just reinstalled 2.2 to see if this will even work on 2.2 so I can isntall GB and try it on there but it didn't work on 2.2 to begin with so I just left it at that and went back to the old method of making it work on AT&T using 2.2.
[Droid 2 Global General] Poryhack:
I'm not pissed at all, didn't mean to come off that way.
[Droid 2 Global General] MeNaCe2s0cieTy:
Anybody know if I can use a Droid 2 Global with a bad ESN with this hack??
[Droid 2 Global General] Poryhack:
Yes you can. ESNs/MEIDs don't affect anything on the GSM side of the phone.
[Droid 2 Global General] leobg:
There is no solution for GB upgraded D2G for AT&T (or any other GSM based operator in USA).

BTW - the experiment you are looking to do will drive you nowhere. You will not get service on AT&T (or any other operator with MCC 310). What you will "achieve" with this is you will lose the 2100 band. And the only way to get it back is to reflash the radio (SBF in other words). Do not do this if you plan to use phone in countries that require 2100MHz band.
[Droid 2 Global General] :
Thanks for clarification, couldn't tell if you were pissed about me asking a question or what. Thanks to internets...lol

Anyways, I know there is not a solution *yet* to make GB work on Droid2 Global for AT&T. I am not sure how I can help with this but I am willing to test things out. I played with quite a lot of stuff but could not find anything. GB won't load on D2 with old Radio and you can't install GB if you remove the radio img from the install. It's not a big deal, I installed hexen for testing today but I backed up my slimmed out Froyo with over half apps frozen using TiBu so I can go back to it eventually but just can't get over messing with the phone. Thanks to Android that I want to do something new with the phone everyday now..lol
[Droid 2 Global General] Poryhack:
Not a problem. Unfortunately from the way I understand things nobody is really able to get anywhere with this hack because of the whole signing thing. If we didn't have to worry about the radio/kernel being signed it could be a fairly trivial hack. Working around a signed bootloader however is NOT trivial. I'm not gonna say it can't be done but in all likelihood it won't be because the Droid 2 (Global) doesn't have a large enough user base to bring in/have the kind of low-level hackers you see working on the likes of iPhone, PS3, etc.
[Droid 2 Global General] :
I did notice coming from Atrix that Droid2 does not have a big enough use base, at least on xda. I don't see half as much action as I saw on Atrix forums. Although, I think guys moved from Atrix as well because once the bootloader got unlocked, it went all crazy and now I guess everyone is working on whatever is new.

Either way, I am happy with Droid2 with or without GB since it fits my needs much better than any other phone. I don't know why it's such a big deal for phone companies to not put a friggin keyboard on such awesome devices. Sprint and Verizon has the best phones at this point.

Maybe it's time to switch :D

Although, I have heard Droid 3 or Motorola Photon is actually carrier unlocked to be used by AT&T, is that true?

Thanks guys.
[Droid 2 Global General] solo0590:
help with root please

Hey guys/gals

I been reading this thread and saw that a lot of you have rooted your droid 2 global to work with tmobile, I been reading other places and it says it is not possible. Tmobile for me would be a whole lot cheaper if I can get my droid global to work on it, could anyone possibly tell me where I can find the steps or how to root it?

Much appreciated it.
[Droid 2 Global General] skinote:
Axl over at rootzwiki has posted a way to have both GB and the band unlock:

I can't post links, but it's something like rootzwiki.com/topic/8326-d2g-gingerbread-hack-for-us-band-unlockers/

I can't get his kernel and rom combination to work at all, let alone with the band unlock. Followed both the instructions in the original post, as well as the one later on and neither work. I get a hung system at the red motorola boot screen. I tried several other variations too :( I'm a sad panda.
[Droid 2 Global General] krazyazy:
Be on 2.4.29

Root/Install bootstrapper

Reboot into bootstrapper

Flash kernel.zip (Do not reboot yet)

Restore nandroid

[Droid 2 Global General] tindall21047:
Oh sweet baby jesus, it worked! The trick was either rebooting after the band unlock (I was doing it all in one shot before) was installed or using the Nandroid backup instead of CM7.1 (as I had been trying). Not sure which but I sure am glad to have a more stable and perform-y version of android on my dad's phone. Boy oh boy did he ever complain at the force closes froyo kept giving him. I'm doing my best to keep him out of apple's walled off garden and all the hoops for D2G on ATT have been driving us both mad. Fingers crossed that he starts to get it. Thank you!
