Just run AOKP 29/4 with Poursinet's build.prop. I switched back to 240 dpi for Play issues. But everything works. Keyboard backlight only works in auto mode (dim settings) and the camera doesn't record video. But that's it. Sent my Milestone for retirement :cool:
[Motorola Droid 4] niai_mack:
having used this for a few days now the phone is very usable sounds drops some times but i think that is just because i am in a low signal area

bit reluctant to update the phone due to the reports here

i have a screen of the versions of every thing i am using to see if this will help
[Motorola Droid 4] highlandsun:
So you're still on the original 215 ROM, interesting. I guess I could try to downgrade and see if things improve for me...
[Motorola Droid 4] vmu:
@ Die Bruine: Thanks but that one seems to make the phome app crash every time I make or receive a call :( Do I still need to apply the RAZR gsm patch?

@Niai_Mack You are using the stock rom? What build.prop did you use?
[Motorola Droid 4] Die Bruine:
I've been using it for a couple of days now. Not one crash yet! Placed and received several calls, no issues there. Takes 3 to 5 minutes to get a signal after boot though. That's pretty strange. And yes I applied the RAZR patch. Just don't forget to replace the build.prop. It wouldn't work without it.
[Motorola Droid 4] vmu:
Reflashed, applied gsm patch, copied Poursinet's Build.prop. No more crashes but still voice issues (low pitched to none) and no data :(
[Motorola Droid 4] niai_mack:
stock i i have done in install safestrap and do the unlock via radiocomm 11.11.11

not had any time to do much more then this
[Motorola Droid 4] highlandsun:
Well, most interesting to me is that you're still on the original .215 CDMA radio. I wonder if the .219 radio is causing problems for us.
[Motorola Droid 4] Die Bruine:
VMU, which version do you use?
[Motorola Droid 4] vmu:
AOKP 29/4 like you said. I'm flashing again as we speak. This time with the Eclipe GSM patch.
[Motorola Droid 4] Die Bruine:
2G works just fine...

Don't bother. I finally found out what it is. Well at least where to look. Turn of 3G and no matter which ROM you're on, audio will work. I just tried 215, 219 and AOKP. They all work over 2G. As soon as you enable 3G you will loose the audio when placing a call. I still don't see how this is different when receiving a call. But at least now I can go back to fully functional 219. Toggling between 2G and 3G to place a call is something I can live with.

I was sitting in the garden working on my RC cars when I had to place a call. It didn't work. Then I noticed the 3G/H sign. I switched to 2G and I could place a call again. I tried 2G with or without data and 3G with or without data. 2G works all the time. I think it was just coincidence that I had 2G coverage when placing calls in AOKP. Now I would think AOKP never worked for me either. All the testing was done inside my house or at work. I bet I had 2G coverage 9/10. AOKP doesn't change the 3G/2G data icon that fast. I guess that's why I didn't notice it.

Well like I said. Just switched back to 219 (modified with RIL, but doubt that it matters) and I have audio over 2G. Tested both incoming and outgoing. Then turned on 3G. Incoming is OK. Again outgoing/placing a call no audio.

I recall a topic about a similar issue with CDMA networks. 2G worked fine but 3G wouldn't. I'll try to dig up that topic. I'm pretty sure it wasn't XDA but I'm not sure whether it was an Bionic, RAZR or any Droid topic. So it won't be easy. At least maybe now you all can use your phone. I mean, switching between 2G/3G just to call someone (or to 3G whenever you need fast internet) doesn't seem bad for the moment.
[Motorola Droid 4] vmu:
Wow thanks, no more voice problems :P

Now that we know this, I think the Radiocomm value needs to be adjusted to enable good working, stable 3g. I wish Disablewong would give us a readout of his Chinese GSM unlocked phone. Until that time I keep fiddling with the Radiocomm settings (as soon as I know where to start :P )

Thanks Die Bruine
[Motorola Droid 4] Gasai Yuno:
Hey, what about USSD codes with responses? Do these work or is it like with the D2G, “MMI complete” and that's it?
[Motorola Droid 4] vmu:
Yes, they work, in every Rom I tested.
[Motorola Droid 4] niai_mack:
thanks for that info the signal around where i am is very bad i must have been on 2g most the time

good to know i can update without loosing the use of my phone
[Motorola Droid 4] highlandsun:
Ok, so that saves me from downgrading back to .215. But doesn't explain my none of my SIMs connect at all. Sounds like we still need more info on that NV edit. I wonder, does that edit only apply to Motorola devices with this Qualcomm chip, or to all devices with this chip. I would figure that Qualcomm supplies the actual baseband firmware.
[Motorola Droid 4] zeroktal:
directions stock rom .219

Im still looking for definite instructions for stock rom(rooted) with .219 update to get this working on t-mobile.
[Motorola Droid 4] Die Bruine:
In that case there is something seriously wrong with your search skills. I posted that the mod works on 215, 219, AOKP and Poursinet confirmed CM9. Poursinet posted in the OP what needs to be done and VMU posted it in the Hongkong thread. But, since it's the second time you've asked....

Download this

And do this:

1. Ensure USB is connected as PC Tools mode (not Mass Storage)

2. In Radiocomm go to MA->CDMA1X->QSC60x5

3. After it comes up, switch to FTM Common1 tab and wait for the phone to enumerate purple.

4. On the upper right side in the NVAccess, scroll to NV item 1877 NV_RF_BC_CONFIG_I

5. Read the value from the device

6. Replace the first 8 bytes (16 digits) with: 8703E80400000200

7. Write the data to the device and powercycle.

This will enable GSM/UMTS bands.​

Edit these values in your build.prop (\system\)

persist.ril.modem.mode =2

ro.telephony.default_network=3

persist.radio.cdma.min = 0

ro.mot.phonemode.vzwglobalphone=1

ro.telephony.gsm-routes-us-smsc = 0​

After that, add your APN manually... And you're off!

Remember Audio does not work when placing a call over 3G. Turn off 3G when you need to place a call. Or keep it on 2G and switch to 3G when you need fast internet.

And to add to that, highlandsun hasn't succeeded yet. So there is always the possibility that T-Mobile is blocked somehow.
[Motorola Droid 4] zeroktal:
strange...but true

Ive spent 3 hours searching for your posts. I dont even see them when I look up your name specifically. Thanks for the detailed instructions. Trying them now.

edit: found posts with your name, but still no detailed instructions. If you get a sec, can you tell me what you searched for?
[Motorola Droid 4] Die Bruine:
Don't worry zeroktal. I wouldn't have helped you if I didn't want to. That's the way most forums work. Complain you need to search harder but help you anyway ;) .

The solution came from the Bionic topic and was posted by "VMU" in this topic.

"Poursinet" came out with a build.prop in this topic. I looked for the changes and applied those to AOKP and 219.

My advice, never search on this site. Use Google ;) . This site has the worst search engine. Except hen you need to search witin a topic.
[Motorola Droid 4] cellzealot:
Here are the zip files for performing the NV edit required without the need for RadioComm. The unlock zip writes the 8 byte string for the GSM band config and the relock zip writes the default configuration back so you can return to stock in the event of problems.

We were waiting to release them with a more complete guide once we had worked through the details, but since so many users are trying this and having varying success while I have been unable to make it work properly on my D4 with T Mobile in the US, it seems like a good idea to post these now.

These files will make it easier and safer to perform the NV edits for users who don't want to mess with a complicated and dangerous serviceware app like RadioComm.

They must be run from Droid 4 Bootstrap recovery on a rooted D4 because Safestrap recovery disables NV writes.

Just place the zips on the root of your sdcard-ext directory and boot into recovery from the D4 Bootstrap app and select Install zip from sdcard, then Choose zip and select the TBH_Band_Config_Unlock.zip and install it.

It takes about 2-3 secs to run and then reboot and you should be all set.

The other pieces of the hack like build.prop edits can be performed manually as per your needs and may not be the same for all users and carriers. There are also edited apns.conf.xml files that have APNs for many more international carriers included and may avoid the need to manually set the APN for your carrier.

I recommend keeping both zips on your sdcard for safety and convenience.

Good luck and please post back your results here with as much info as possible so we can develop clear set of instructions and steps for various carriers and configurations.
[Motorola Droid 4] pvillasuso:
Thanks for this ! :eek:

I used it with an ICS ROM , with a CDMA RAZR XT912 ,and it worked perfectly !

also applied the GMS patch !

---

One question , how to enable data ? :confused:

GMS voice calls are ok [ 1800 band in my case ] , same as SMS

APN is fine , and enabled , but it wont connect to 3G data [ no 3G or H+ icon ]

Any clue ?

Thanks in advance

Regards

droid 4(vzw) .219 update

This did not work with droid 4(vzw) .219 update. I have a recent t-mobile microsim. No at&t to check it with.
[Motorola Droid 4] cellzealot:
We have a Chinese eng RAZR ICS build that has a fully functional band unlocked radio. It will not flash on stock hardware, even just the radio fails asserts, but we have dumped the NVM and I am in the process of comparing them. There are a great number of differences that need to be examined and evaluated, but the value of the 1877 string is different in the first 2 bytes. You may want to try this string out on your ICS RAZR and see if it has any effect on data.

NV_RF_BC_CONFIG_I 1877 8001E80400000200

As I said, there are a great many other potential factors, but your partial success is hopeful and possibly helpful too.

Flashing of that RAZR AOKP patch may make things more difficult to figure out because of all the changes introduced by that patch.

So far we haven't been able to make this work properly on the VZW RAZR ICS leaked build either, but that doesn't mean it won't work r that someone else may have different results.

The number of NV Items that may impact the problem is too large to start posting other suggestions right now.

I will post an NVM table we have that is read using RadioComm in a different mode(NV/SEEM) that pulls basically all of the readable NV from 0000 to 2DXX in a single operation, which is 12030 Items and can be very useful for comparing different devices and builds.

Right now I only want to post things I am fairly certain are safe.

Thanks for the feedback and we should probably start a thread in the Razr section to avoid confusion and raising hackles.
[Motorola Droid 4] pvillasuso:
Tried but didn't work as expected , got stuck a bootscreen :D

Gonna try it with a GB ROM !

Thanks so much for all that interesting info :eek:
[Motorola Droid 4] Die Bruine:
I've done some research on the 3G outoging calls. The only thing I could find was one reported bug on the Legend. Where incoming calls were fine, but outgoing had no audio. This was supposed to be due to the fact that when you place a call the codec is determined by the receiving end. This could explain why audio does not work when placing a call.

Another bug was with the Iphone 4s. You can find thousands of reports on this one. Exactly the same. When placing a call on 3G the audio wasn't there. Receiving a call worked. Workaround was the same, switch to 2G.

The fix? Apple rewrote the baseband. So it would seem that in order to get audio working over 3G, we have to wait for a new/improved baseband.

@ Pablo,

Did you try adding the APN manually? Mine also doesn't work unless I add it manually and set all options (no default but PAP for example).
[Motorola Droid 4] pvillasuso:
Yeah I tried manually , its very easy with my service provider

Name: ICE

APN: Kolbi3G

Thats just it ... :D no more info required ..

Installing a stock GB ROM , the razr is my spare phone ! , got a Samsung Note as primary :rolleyes:

[Motorola Droid 4] beflythis:
Hey guys,

From a droid lover, just wanted to say thanks to everyone who's contributed here for sharing. I was debating buying a Droid 3 vs a Droid 4 (obviously would love the D4 with double the ram and NFC support), and I think I'm going to give the D4 a shot!!

I'll be buying off ebay... (unless someone knows a better source?) But wanted to ask:

Is there a specific model or version I should be purchasing that only has GSM support, or will any (Verizon or non) Droid 4 device work? Yes, I'm aware I have to IMEI unlock it, before going to town on it for GSM support.

Thanks again,

beflythis
[Motorola Droid 4] munchy_cool:
^^^ try the xda marketplace ...you may find a better deal than ebay there ..
[Motorola Droid 4] Dave Lister:
The only Droid 4 out there I'm aware of is the Verizon version. If it had been released by another carrier, it would have to have a different name because Verizon licensed the Droid name. Also, the current hacks to enable GSM support do not require any kind of SIM or IMEI unlocking.
[Motorola Droid 4] gtmaster303:
Will the Droid 4 work on AT&T now with this hack?
[Motorola Droid 4] vmu:
Yes, it should work. Tested it with an At&t sim. Although roaming as I'm not in the US right now.
[Motorola Droid 4] niai_mack:
been playing around with a few roms now and some of them ones like AOKP will not let me send or receive SMS, the MIUI alpha build to will receive them but not send

any ideas? i think i must be something to do with the unlock

Here's an idea for your 2g 3g voice issue on the DROID 4. I remembered this from the x.
[Motorola Droid 4] vmu:
Thanks for the tip. Unfortunately the Droid 4 does not have the vocoder option.
[Motorola Droid 4] zwierzak:
Did really D4 have NFC? I didn't find such information.
[Motorola Droid 4] podspi:
Yea, I don't think so. Though it probably supports an NFC sdcard. Problem with those things is they are all ~ 1gb. Not as a big a deal since the D4 has an 'internal' sdcard, but meh.

I am a little disappointed that NFC wasn't included with the D4. It is such a shame there is such little interest in keyboard-superphones these days. I was in heaven with the D1...
[Motorola Droid 4] highlandsun:
The vocoder option is there, but it only affects CDMA. On GSM you always get the GSM codec, that's just how the GSM standard works.
[Motorola Droid 4] IVAN-ICE:
Help

Hi! sorry of BIG offtopic, but I need your help. I can't starting gsm module on cyanogenmod 7.2 my device (not LG). If i copy libril-qc-1.so on stok rom android 2.2 output error: dlopen failed: Cannot load library: reloc_library[1318]: 934 cannot locate 'dsc_wds_modify_profile'...

Very much I hope for your help, many thanks. )
[Motorola Droid 4] redddog:
Why you gotta be like that?
[Motorola Droid 4] highlandsun:
Ok, I'm back in Ireland now, and my 3 SIM is working fine. I haven't tried any calls yet, but I immediately received a text from 3, and then a settings update message, providing the APN info. 3g data worked immediately after accepting the settings update. The data icon just says 3g, not H, but the phone info shows it's on HSPA.

So, it seems this phone behaves like a lot of other Verizon worldphones, it disables GSM support within the US but works elsewhere.

This is on my basically stock .219 system, with the minor build.prop tweaks and no other changes. (No changes to the ril libraries.)

[Edit] OK, dialed out to one of my other numbers and left a voicemail. It recorded fine, sounds perfect.
[Motorola Droid 4] cellzealot:
Yes, and the new ICS 4.0.4 leak has this string in place and global services work out of the box on overseas networks, but not on US GSM carriers.

Isolating that lock mechanism and disabling it is where I have been focusing my energy.
[Motorola Droid 4] Rick#2:
I can second the notion that the voice issues seems to be isolated to the USA; I'm in Canada using Bell and everything is great over 3G. We don't even have the option of using 2G for voice and I have no complaints with either incoming or outgoing calls, or data for that matter.

The only thing I've noticed is that the signal indicator seems to underreport the reception I'm getting.
[Motorola Droid 4] Rick#2:
Oh yeah, and forgot to mention I'm on .219, haven't rolled the dice with the ICS leak.
[Motorola Droid 4] highlandsun:
One more note: usb tethering won't work unless you have "dun" included in your apn type. Just found this out tonight. Also, the settings / apn editor won't let you set it; I used the sqlite3 binary to set it manually.

Also it appears that roaming is not allowed at all. Still trying to figure that out.
[Motorola Droid 4] GermanGuy:
Where would I find the edited apns.conf.xml files? Thanks
[Motorola Droid 4] calebu2:
Dumb question: am i right in thinking i need to install a custom recovery to flash the gsm fix on stock 219?

Or can i flash it using adb?

One of these days ill do this regularly enough to figure it out myself.
[Motorola Droid 4] GermanGuy:
I applied the unlock.zip via Safestrap recovery but still am not able to select GSM after reboot. Only options under "wireless& networks - mobile networks - network mode" are CDMA/LTE and CDMA only. Any other thought what I might be missing? Thanks
[Motorola Droid 4] cellzealot:
where are you located?

What type of SIM are you using?

Have you tried setting it to WCDMA Preferred in the Phone Info menu?

My D4 is on the ICS leak now, but when it was on 219 stock, using this edit allowed it to show the global network options with my T Mobile SIM inserted despite the fact that I could not get any service because of the US GSM carrier lock. I can also select the T Mobile APN and it sticks, but still no service.

If you are trying this with an ATT or T Mobile SIM in the US it will not work.
[Motorola Droid 4] GermanGuy:
I am in the US and trying out a german SIM card. Where should I look to find the global network options? I don't see them? I am kinda lost. If somebody can guide me through this I'd greatly appreciate it.
[Motorola Droid 4] GermanGuy:
Bump.

Need some help please.

I have tried both a foreign SIM as well as an AT&T SIM. I get the message "SIM from an unknown source". What is the next step? In settings, wireless networks, mobile networks, I see only 2 options: 1. CDMA/LTE 2. CDMA only.

If I go into Network app (from the market) and select GSM Auto, I get new options to select an operator in settings. However, after searching for an operator it never finds a network. This is with both the At&t SIM card as well as a german SIM card.
[Motorola Droid 4] cellzealot:
That message always comes up and can be ignored.

Use AnyCut from the Play Store to set shortcuts to Phone Info and Programming menu as they may help you debug this problem, but it is not going to work in the US until and if we are successful defeating the lock.

The Phone Info menu is where you can set the radio modes and force WCDMA preferred from the drop menu. The Programing Menu will also give you access to many low level settings as well.

You are going to have to play around and find out what works for you.

There are many variables in the user reports on the devices which are using this exploit, so there is not a fully established method.
[Motorola Droid 4] highlandsun:
You're not going to get any success at all while you're in the US.

Also, as I already posted earlier in this thread, the phone seems to disallow any form of roaming. My Irish SIM is working OK here in Ireland, but it disconnects when I go out of the home network area - it doesn't connect to any roaming networks. (It roams fine in my TouchPro2.) It likewise would not connect while I was in the US (but in my TP2 it connected to AT&T roaming just fine).
[Motorola Droid 4] GermanGuy:
Ok. Thanks. I hope Verizon will implement the roaming feature (at least outside the US) once the global features become official. I tend to travel a bit and it would be silly to have to get different SIM cards for different countries especially when you travel in Europe.
[Motorola Droid 4] gtmaster303:
We need to get a thread stickied with a step by step tutorial of how to do this hack pronto. Can't wait to try this out on AT&T in the US
[Motorola Droid 4] cellzealot:
If you read the thread you will see as has been repeated many times already, including twice on this page alone: THIS DOES NOT WORK ON US GSM CARRIERS!

I have been trying to figure out why that is and how it can be enabled, if at all possible,

but that is why there is not a stickied thread with method and instructions because it is not successful yet, ok?
[Motorola Droid 4] gtmaster303:
sorry, didn't read through the thread... last post I read a while back told me I could
[Motorola Droid 4] xixx:
On the Droid forums people saying that the latest (206) ICS leak has enabled Global mode. We need just insert the SIM and it will ask to turn Global Mode on.
[Motorola Droid 4] e183348:
Hi guys, I was wondering what bands are working with the GSM patch? In particular I'm using 900, 1800 and 2100 in my country. Thanks!
[Motorola Droid 4] Edwii:
Hello, Long time reading first time poster.

I am very interested in getting a Droid 4, and I realize this may be rehashing what's generally already out there I am just hoping for a more specific answer.

I am from Canada BC, I am wondering if i buy a droid 4 at this time, as of now how well will it perform on our networks?

I apologize for the next possible noob question: Once I have the Droid 4 in hand, which are the most up to date steps I need to take to get it working on our networks?

Thank you for your time and patience.
[Motorola Droid 4] danifunker:
Currently I am running droid4 on ICS leak and it works great. The battery is MUCH better than what I ever had on my xt860. I am on Rogers and have a fully functional experience right now, without LTE:

Sent from my XT894 running ICS
[Motorola Droid 4] Edwii:
What do you mean with out LTE? I thought we had LTE up here and that it was a good thing, Do you mean rogers/fido doesnt have lte or that the droid 4 doesnt have LTE after using the ics leak?
[Motorola Droid 4] GermanGuy:
Droid 4 is a Verizon LTE phone, meant to be used on the Verizon LTE network in the US, not Canada. GSM is global.
[Motorola Droid 4] danifunker:
LTE up here is based on the higher bands. Verizon LTE operates on 700mhz, we haven't had the auction for that spectrum space up here yet...

That, and the fact Verizon LTE probably uses CDMA for voice technology, there may be ways on getting it to work, but I think the band might prove to be a limiting factor.

Sent from my XT894 running ICS
[Motorola Droid 4] Edwii:
I understand now thank you. That being the case, if i were to compare the droid 4 to a Canadian specific phone, would I notice a difference on the network end of things? (data speeds, voice clarity, etc?)
[Motorola Droid 4] danifunker:
With the ICS leak (I'm running running .206) I can tell you this is *really close* to any experience you will get on a regular Canadian HSPA phone. I have had no voice call quality problems, and everything works as expected. The only thing is that I can't seem to find french language options, but maybe I didn't look hard enough.

Here are the speed test results, I'm on Rogers in Toronto. This test was done indoors.
