I'm thinking I'm going to go with the custom ROM route and just compare the files in a good text editor. One lazy afternoon, when I have the time.....
[Motorola Droid 3] RWALEY:
What did you add to it? Anything that would further assist AT&T 3G?

Still working on making more changes here and there to the build.prop. I am pretty sure I can mod it a bit more to make the phone identify as an XT862 instead of XT883.

Also, still trying to isolate the bare minimum needed to run the modified XT883 radio so people can copy/paste into build.prop files of their own.
[Motorola Droid 3] BenSWoodruff:
That sounds like an awesome idea. I'd love to get a custom ROM running now whilst I wait to get back on Verizon (for CM9, since it doesn't work on gsm with this hack).

As far as I know, the main requirement for the build.prop tweak to change the phone's identity is so that it will work with the radio. Maybe I assumed, but it makes sense to me lol. I can't imagine it could use the radio if it knew it wasn't the correct phone for that radio.

Here are my build.prop edits (not pertaining to the gsm hack—scroll through the whole code box lol):

# EDIT EXISTING PROPERTIES WITH FOLLOWING:

[Motorola Droid 3] HerbK:
Now I'm using SKT(Kor) but SKT's 3G is WCDMA. Then I follow this method and unlocked my Droid3? SKT's Baseband is WCDMA 2100mhz, CDMA 800mhz.. If I use CDMA, data isn't work.

Sorry for my English..
[Motorola Droid 3] RWALEY:
Cool! Thanks, I will look it over.

I have been running my custom build.prop on different ROMs without issue.

Currently using Eclipse but I was testing it with Maverick and Liberty too.

Only some issues with apps thinking it is an XT883 instead of an XT862. I don't think it is a big deal and the only app I have found that crashes due to it is the myATT app. Should have a workaround for that though.

---------- Post added at 01:40 PM ---------- Previous post was at 01:38 PM ----------

Yes, the WCDMA/UMTS should work as the XT883 radio supports 850/1900/2100

CDMA is not supported using this custom radio. Unless someone hacks the XT862 radio baseband it probably never will.
[Motorola Droid 3] RWALEY:
Well, it turned out to be much easier than anticipated.

Simply edit the "ro.product.model" on the build.prop

If you are having issues with the phone identifying as an XT883, just put DROID3 in that field and it should solve it.

Use the Android Market identification to confirm what your device is being seen as.

However, you may receive unwanted OTAs.

While it was identified as an XT883, it tried to download a China Telecom update.

You can edit the "ro.build.display.id" to throw it off.

It appears that "ro.build.id" might be the necessary string to run this radio on any ROM. Still testing that out.
[Motorola Droid 3] BTLINU:
Thanx RWALEY for this tweeks.

Am outside the US, and my country is using:

GSM 900, GSM 1800, UMTS 2100 and i want to change the default network type to GSM/UMTS, what is the default order for network types or where could i find that, am using the stok xt862 radio:

1. ?

2. ?

3. ?

4. ?

5. ?

6. ?

7. Global (default)

And I want to use your GSM SIGNAL IMPROVEMENT tweeks but i dont know if those will be compatable in my area, Could you please put some light on that or guide me to the right direction because am frustrated:mad: from the frequent signal loss.

Thanx...:D
[Motorola Droid 3] sic4672:
noob question... can the radio.img be flash via an update.zip through recovery, or can it only be flashed via fastboot through a PC?
[Motorola Droid 3] RWALEY:
#3 is the default for UMTS/GSM automatic I believe.

It is under "ro.telephony.default_network"

As far as the tweaks for signal, I am not sure if it will help you but I do not think it will hurt anything if you try. It definitely helped me. It may have something to do with the 1900MHz band only though. I do not live in a market with 850.

There were some other small changes made throughout the build.prop as well, mostly related to defaulting radio settings to GSM.

If you are using XT862 stock you definitely want to adjust the Verizon modifications to see accurate signal:

http://xdaforums.com/showthread.php?t=1326310

If you do not plan on using CDMA at all you could also attempt to flash this XT883 radio. Perhaps the GSM signal quality is better than stock XT862? I would not know as Verizon has locked USA frequencies on stock.

---------- Post added at 08:41 AM ---------- Previous post was at 08:39 AM ----------

Pretty certain it has to be done through fastboot.
[Motorola Droid 3] BTLINU:
Thanx for replying.

I had used both radios xt862 and xt833 with build.prop modifications mentioned in above link, also tried your attached build.prop with xt833 radio.

Full bar signal, no chinese letters, no fc. Thanx:)

But my question is different:

How could you tell that #3 is for UMTS/GSM not CDMA or something else since there is #7 (global) which means 7 choices.

Also when comparing your modified build prop with the original xt833, in addition to all usefull modifications, you added some GSM signal improvements at the end of the prop starting with ro.ril. , my question is here: are those parameters compatable with all gsm networks or just US ones. because i didnt face any difference by adding them.
[Motorola Droid 3] RWALEY:
#3 was the UMTS/GSM Preferred option on the XT860 Bell Canada build.prop

It appears that this is consistent among all of the XT8xx variants.

leobg also confirmed that #3 is for UMTS/GSM. 2nd post of this thread.

The signal modifications may just be for US GSM, in fact they may just be for US GSM on 1900MHz.

I have not been able to test anything other than that.

Have your data speeds changed since upgrading to this build.prop?
[Motorola Droid 3] BTLINU:
I didnt have chance to compere since i moved back to xt862 when no deference found, but i will flash xt833 again and give you the speed results.
[Motorola Droid 3] fl4r3:
I may be wrong, but I think the numbers correspond to the choices in the list shown when you type *#*#4636#*#* (then going to phone information and looking at preferred network list).

The 7th option is GSM/CDMA auto (PRL), while the 3rd one is GSM Auto (PRL).
[Motorola Droid 3] BTLINU:
What i can see on my part is:

1. WCDMA prefered

2. GSM only

3. WCDMA only

4. GSM auto (RPL)

5. CDMA auto (PRL)

6. CDMA only

7. EvDo only

8. GSM/CDMA auto (PRL)

9. Unknown

This is on xt833 radio.

Edit: Also it is the same on xt862 radio.
[Motorola Droid 3] BTLINU:
with xt862 radio (Just EDGE Available)

Also on xt833 radio with the modified build prop (Just EDGE Available)

I think it didn’t catch the UMTS 2100 Network, because when switching to 3G only, there is no signal available, and on *#*#4636#*#* menu, it is automatically switched to WCDMA only.:confused:
[Motorola Droid 3] RWALEY:
Both the XT862 and XT883 radio are 850/1900/2100 for WCDMA

Do you get 3G when using the stock build.prop?

Also, make sure you have entered your provider APN info correctly.

Ok i dumped and searched through all of /dev/block mmc's and got nothing...

i would like to decompile this radio.img since i flashed it and now can bypass emergencey only screen and network unlock screen...

It just hangs with like theres no sim card... also tried unlocking through radiocomm, status says its unlocked with the radio posted here, but yet still asks for the code... i wonder if resetting the code is an option to all 0's?

my phone is locked im still looking for an unlock solution other then a code...

tried htc's gfree but when i looked at the gfree.c it is attacking a block that isnt there... so if i can figure out the file to attack gfree should be setup for it would just need to edit the source code and recompile...

I did this mod to a droid 3 I have that I'm going to sell. Seemed like a value add that it can go on any network. Is there anyway to connect it back to Verizon 3g with this mod or do I have to go back to stock radio?
[Motorola Droid 3] tspx23:
Although you could get it to work on verizon 3g. If you are selling to someone with verizon its always better to flash the stock radio
[Motorola Droid 3] jaypeezee:
Can someone lend a hand...

So I just acquired a Droid 3. I went ahead and followed the directions and obtained an unlock code from moto4unlock.com - $6USD and was sent to me within 30 min.

The first time I followed this thread, every time I inserted my ATT sim (prior to unlocking) I would get the "Unlock Code Screen" where it forces you to input the unlock code. After obtaining the unlock code from above, I went ahead and unlocked. What was surprising, is it did not tell me "Unlock Fail" like this thread stated it would - it actually said unlock successful.

Anyway, moving forward - I went ahead and completed the rest of the steps. After updating the build.prop file, I was able to make calls, and data worked. Well, I had purchased this phone for my mother and wanted to remove my google account and use hers. I didn't realize I couldn't just "remove" the account, instead it was telling me I had to do a hard reset. I went ahead and reset the phone and noticed I couldn't obtain a network signal.

So, I followed the link in the first step by going back to Stock Firmware - I noticed after the install completed, I got a roaming triangle with my att sim and vodafone/verizon sim. (Prior to doing it the first time, I never had a roaming signal so no idea why it has one now)

What I also noticed is when I inserted my ATT sim it did not prompt me to "unlock" the phone again like it did the first time.

So I continued with the rest of the steps. After flashing the new radio and updating the Build.Prop, I get a red circle with a line through it over the signal bars. I've selected GSM/UMTS and no luck...

Any ideas ?
[Motorola Droid 3] Legacystar:
could you explain how to get it to connect to verizon with the xt833 radio?

[Motorola Droid 3] eww245:

[Motorola Droid 3] rquinn19:
Thanks everyone for all the helpful info. Did this last night and I wake up to a guide. Figures. I didn't have any real issues though.

Thanks again.
[Motorola Droid 3] jaypeezee:
Queberican,

Couple things;

At which point do you change or select GSM/UMTS in Network setting - before or after flashing the new radio?

also

In your "All In One" download you have 5 folders; boot, Flash_Verizon, Modified_build.prop_v2, Root v1.07, and Unlock.

You state:

I am confused as which one to copy to the phone ? the one in the v2 folder or in the Unlock folder.

Last and final, your version of root explorer is giving me FC's so I used root browser instead- FYI.

Still running through the steps as I post, will update later.

UPDATE:

Still no dice... I'm having the same issue that i was having, prior to requesting help; the phone process keeps force closing after flashing the new radio. I noticed that after pasting the new build.prop (from modified v2 folder) the permissions were wrong - so I fixed them.

Any other options - I want to throw this phone out the window at this point.

UPDATE #2:

So I went ahead tried all the steps, and modified them a bit, after following them to the 'T' MULTIPLE times.

Booted into recover, wipe data/cache

Flashed 890 stock firmware

Rooted

Replaced Build.Prop

Updated APN's with straighttalk APN (thats what I am using)

Selected GSM/UMTS

Rebooted and Flashed 883 Radio

.... AND same ****.

I get no signal, and "process.android.phone" has stopped repeatedly unless I put in airplane mode.

I know it has NOTHING to do with my straighttalk sim because I was able to place calls the first time I followed this method... UGH.

UPDATE #3:

HOLY SHEEEEEEEIIIIIT.

After typing this update, I tried to access the mobile networks page just to see if I could get into it and noticed (before the FC's) it was selected to GLOBAL. so I was able to select GSM/UMTS once more and VIOLA !! instantly started receiving text messages.

I just updated my APN's and BAMMM all is working
[Motorola Droid 3] rquinn19:

Will I get HSPA+ on AT&T or just regular HSPA?
[Motorola Droid 3] ekramsam:
I've heard the droid 3 supports HSDPA+ but I haven't noticed any speed increase over my old Galaxy S. Speed test results are identical.

EDIT: Forgot to mention the speed test were done in NYC
[Motorola Droid 3] RWALEY:
The Droid 3 is definitely compatible. Some people get the HSPA+ speeds and some don't, found out a bit more why.

It will only work if your account is provisioned to use it now.

Your myAT&T page needs to show your data plan as "DOM - HSDPPB"

If your account does not have this type of data plan then you will only have speeds up to 5.76Mbps on HSPA.

---------- Post added at 06:52 PM ---------- Previous post was at 06:47 PM ----------

Very interesting.

Does the new XT883 package have an update to the radio?

Perhaps a new fastboot radio image can be made if there are any improvements?
[Motorola Droid 3] ChocolateShein:
I'm not sure how to check if I have the DOM - HSDPPB on myAT&T, but I'm on the data unlimited plan for non-smartphones, so I probably don't have it. Is there any way I can get it without losing unlimited data?
[Motorola Droid 3] RWALEY:
It will be on your view recent usage page, under the data plan. Usually the non smartphone data plan will be DOM-DPPB or DOM-GPRS-UNLTD. Both of those unfortunately will not allow HSPA+

I have the HSDPPB provisioned and I am on the old MediaNET plan. Some people have it, some people don't and nobody is entirely certain why.

What custom roms are working nicely on ATT? I'm using Liberty now and it didn't require any hoops to jump through.
[Motorola Droid 3] sic4672:
Did you merge the build.prop for liberty with the modified prop for this hack? If so can you post a link to it? Thanks
[Motorola Droid 3] RWALEY:
In theory, any custom ROM should work as long as you flash this radio and use the custom build.prop

I tried a bunch out and personally settled on Eclipse mainly due to that one getting a little better battery life. Although I have not tried any of the newer CM9 Beta versions.

---------- Post added at 01:04 PM ---------- Previous post was at 01:02 PM ----------

You should not have to merge anything. Not certain if Liberty has anything specific to their ROM in their build.prop but I used my build.prop on multiple ROMs without merging anything.

Is there a way to unlock this phone without having to purchase a code? Also if we replace the radio on this phone using your guide, you mention it work for att and tmobile but will it work outside the country with all carriers?
[Motorola Droid 3] tspx23:
you don't need the guide for out of the country.

you need to pay for the unlock code, there is no way to unlock it otherwise
[Motorola Droid 3] xterminater07:
So if I pay for the unlock code will I still be able to use it on att and or tmobile? That's what I'm trying to ask you because I wonder if I have to download your modem and buy a code for it to work with carriers outside the US and in US.
[Motorola Droid 3] RWALEY:
You will have to get an unlock code no matter what you do. The SIM is locked unless you unlock it.

You only have to use this radio hack to use it with ATT/T-mobile in the US. No hack necessary outside of the US.

This radio hack will work both in and outside of the US if you wish to use it.

[Motorola Droid 3] RWALEY:

The LTE radio might work on AT&T though but voice calls would operate on GSM.
[Motorola Droid 3] tspx23:
a lot of the people with the droid 3 are using it on tmobile 2g so... it might be worth just picking up a droid 4.

Just checked with someone who has one, it is. Phone is SIM unlocked but no signal with a T-Mobile SIM.

I believe a Milestone version is coming out soon so it is possible that your radio.img method could work from that phone.

[Motorola Droid 3] RWALEY:
I found it was easier to perform this process after you flash your desired ROM.

The only thing you have to be aware of is potential tweaks your ROM makes to the build.prop. In most scenarios, using the v2 build.prop file will work with most ROMs but it is possible that something necessary could be needed by that particular ROM.

Also, it may take a couple of reboots for everything to work properly after you have copied the build.prop over.
