[Q] Sprint Tab; want Gingerbread; don't care about phone service

I have a Sprint tab. I wan't to upgrade to gingerbread, and I don't care about CDMA service, but I have to have wifi. GPS would be preferred but I can live without it. It would also be nice if it wasn't a brick afterwards.
What are my options? Can I just flash Overcome without a modem file? Is there some sort of null modem file I can flash? Is there a different ROM or kernel I should use?

Also very interested in this.

I recently put quite a bit of effort into getting GB to run on my Sprint tab. I use WIFI only so I was not concerned with a working CDMA radio. I attempted to flash the European GSM firmware to my device. I tried flashing the kernel and system only, leaving the CDMA radio file intact. I also tried flashing several GSM radio files to the device. In the end I was unsuccessful, and it took several hours to recover the device to an operational state.
If you WERE to get GSM GB working, there is a good chance that GPS and BT wouldn't function. That's kind of a deal breaker for me.

tldr; Sprint users are screwed until the official release of GB because the Overcome team doesn't care about us and the only guy who seems to know how to work the CDMA is making a crappy honeycomb build instead.
IMHO other devs should make a version of the ROM with all data taken out because it'll work for Sprint users and GSM users who tether instead of paying out the rear for a data plan on their tab.
----------------------------
tonman23: Thanks, but i was looking for gingerbread, not honeycomb. It's great that spacemoose can prove it in concept, but I don't like the honeycomb interface, and I'm not interested in flashing a half broken version of it to my phone. I want a stable gingerbread build for the improved performance and minor UI features.
etvaugha: BT & GPS are handled by chips completely independent of the modem. I can't post a link because I'm still new here but the ifixit galaxy tab teardown shows clearly that GSM tabs have distinct BT/WLAN & GPS chips. That's pretty standard fair for android devices, so I doubt they changed it simply for the CDMA models.
It also clearly shows that the modem is a GSM only chip, so the bin files are completely incompatible. The only solution is ROMs that will boot even if the modem isn't working right.
----------------------------
According the the Overcome 2.0 FAQ, the problem is that the phone won't finish booting if a valid modem.bin is not installed. Apparently the phone waits indefinitely (one user, PFOI, mentioned something about it working after 30 min or so) or crashes during the boot because it doesn't get a proper response from the modem chip.
This could easily be overcome if the devs would compile a WIFI only version of the rom/kernel, that doesn't require or support either modem (CDMA nor GSM). It seems to me that the this would be good for both sides, as the data plans for tabs are a rip off and smart users are going to tether their tabs in a mobile situation anyway. It would also probably be better for battery life considering there'd be one less chip running and less bus activity.
I'd imagine all that would be required is removing the modem initialization during the boot sequence. There might be a need to replace the functions that query the modem's status with static value return statements, but when the tab first boots it reports no service, so it's got an inherent ability to deal with not having network access. All that's needed is a couple little snippets to tell the device it doesn't, and to keep it from trying to get it.

Updated RIL (6.8.11)

Hello all, hope you are all good
I've had an updated RIL posted over on the Kaiser forum for a while now but for those that haven't seen it I don't know of any reason why it wouldn't work for you guys with your Vogues.
To install simply unzip the download and put the androidupdate.tar in the andboot folder on your SD card, then install like any other update in the android installer menu.
There are a lot of changes most of which relate to general responsiveness, signal strength detection and reliability. Let me know if there are any problems on the Vogue.
The modem app included in most builds isn't really necessary anymore so I recommend just enabling and disabling through the android setting but each to there own.

hi
i have updated your drivers
but it doesn't work with Donut?

I tried to install this update but after I did, my phone would never aquire my carrier's signal.
Sent from my HTC Kaiser/Vogue using XDA App

hello
i used this ril on my sprint vogue and it sits there searching for signal the whole time, cant connect.
i did notice that before the boot animation comes up, the little block of code says something like ro.home.operator.numeric=4 which with hyc's work over for tp2 means its trying to get into cdma operation.
seems on the right track to real cdma ril on our hardware, hyc mentioned when i asked him a while back that wrong radio commands (i think htcbsinfo maybe?) was the culprit why it wouldnt connect, and network location was part of it too.
thanks for your work, hopefully this may help in some small way

doesn't work
I have a verizon on Fat Free RLS5 - odex.
Cannot find network...
In conclusion, this does not work w/ the vogues', please adjust settings accordingly

[SELFKANG AOSP ROM] CyanogenMod 7.1 GSM Version [UPDATE 10/23 AM]

I was sent this by XDA user: coreless88 who asked me to post this in the dev section (he doesn't have enough posts yet).
** WARNING: I HAVE NOT TESTED THIS PERSONALLY -- USE AT YOUR OWN RISK -- KEEP A BACKUP HANDY **
** THIS ROM IS INSTALLED WITH SAFESTRAP BOOTSTRAP. DO NOT USE KOUSH'S BOOTSTRAP OR YOU WILL SOFTBRICK YOUR DEVICE **
I dabbled in files for some time, twaked the build.prop a little (added some generally known hacks into it for faster touch reaction, better HSPA reception etc.), and added some files .lib/.ro files from Droid 2 Global.
It all worked out nicely. However, as I cannot use a CDMA network (I live in Turkey, so I have only GSM access), I cannot guarantee this will work with CDMA too. I will appriciate it if someone can test it.
Also, Your GSM card will be recognized instantly, but you need to activate the 3G network form the settings, you will need to add your APN manually, atleast in my case I had to put my carriers APN into the list, so this might not be necessary."

Thanks needs to go to Hashcode, as I just modified and added a missing feature to it.

Thanks for the help Hashcode!
I got my clearence to Dev forums, so I will try to contribute even more to this community =] .
First of all, as in my quote in the first post, I cannot guarantee this will work in CDMA network, Hashcode will inspect the files and try to integrate the GSM feature to his original release.
You can find a screenshot of my phone working under the GSM network and 3G enabled.
!!!However, just like any other custom rom, I cannot accept any responsibilities if this rom bricks your phone. !!!
For installing, just use Hashcode's safestrap, for the rest i think you know the drill.
BUGS:
Videos dont run,
Sound is low,
Bluetooth is broken,
Camera is broken,
Also be aware, notification and ringtone sounds are silent by default, you just need to go to settings menu and choose a ringtone for yourself =] .
Edit: Also as I have only 1 Droid 3 at the moment, I need as much testers as I can find for checking if this works for all Europe SIM Cards.

Referved for future use/updates/etc...

Awesome, very thanks to both Hascode and Coreless88
All work fine in france the signal bdm hspda is very good, than the xt883 rom. Exept the camera all work fine for me.
I'm test, if you want, all other release in france, on bouygues telecom.....

thank YOU !! Hashcode and Coreless88

No thank you guys, for trying it and giving me an easy breath as it is my very first development attempt!

Also I forgot to mention, my tweaks and Cyanogen codes makes GSM reception and HSDPA signal is much more improved than the stock XT862 Rom.
Right now bluetooth doesn't work, but GPU and CPU working properly, if not better than before.
Here are some more screenshots, for Quadrant, SpeedTest, and A Samurai Vengance 2 (BTW Game runs incredibly smooth).

one another bug, i'haven't delivery report on sms/mms, there's no sound in the build speaker when i phone or receive call, and the sound is very quiet in the speaker phone or handset.

Hi,
First of all, thanks for your input. I need your opinions to make this better. So here we go,
All notifications and ringtones are silent by default.
You need to get to:
"settings>sounds>ring tone/notification tone" menus and choose your ringtones from there.
Sounds are in this built generally low, because there isn't any proper sound resources prepared with OMAP 4 series of SoC's. I will try to enhance them, but I will need time.
But you can make the phone louder on the speaker by going to:
settings>cyanogenmod settings>sound menu then choose the settings you like the most.

Hi,
I've added Tweaks for getting stronger reception, making the GSM default network at the boot, tweaks for faster response, etc... You can download the file and look at the system>build.prop (open it via wordpad if you are on windows) and compare it to Hashcode's build.prop.
BTW I am experimenting with audio and video files right now. Post I will post the results when I finish the testing.

Could I apply these build.prop changes my XT862 rom?
Or did you use droid 2 global hacks like someone tried before?

Why not, this is a free world, and as long as you know what you are doing you will be safe, but if you're not...
Be aware, "build.prop" is a very risky file to touch, and has a central role for the Android to run correctly. I had to use RSD to get back to original software because I stuck at the Motorola logo after some changes. So I took the hit for you allready =].
My advice, directly flash this rom and don't do any editing. Because I did not just edited the build.prop, also added several library files, done a lot of testing, finded new libraries or edited them to make it work.
It will include lots of time, effort, patience and hell of a risk.

Oh!
I completely misunderstand you, I thought you were asking about Hashcode's Cyanogen release. You cannot use these fixes for Motorola roms or any rom that based on a Motorola rom. These fixes and libraries are only for Cyanogen builds, at least thats what I think, as I don't have any development experience with any Motorola rom.
You may try, but that will only make the risk even bigger.
Please be patient, I am trying to fix camera and sound problems right now, and I will try to fix bluetooth in a later date, as I didn't see anyone using bluetooth for ages =] .

Giving this a whirl on my xt860 right now, will edit this post with results. Very nice fellas, thank you both very much! Just want to make sure, this is built for Hashcodes safestrap?

Yes, as I wrote elsewere looks like the wrong signal measurement is a purposely limit introduced by verizon request.
On D2g is the same, the Cyanogen rom, with the same radio have the correct measurement, the XT883 too.
So could be interesting to understand where that three bars are lost and if a quick fix for the stock ROMS could be possible.

Hi,
Your thanks are appriciated, and I am sorry for this rom also did not worked for your XT860 =/ . I guess Motorola did everything they possibly can to protect their region based software versions.
I guess the fix will be simple, but I am afraid either Canadian Android developers are rare (BTW I don't think so), or they don't want to develop for / they don't have this device.

Indeed, It seems low GSM signal was the goal for them. Either for the purpose of making the Verizon "look like" superior to European Networks, or just for making it a Verizon semi-exclusive and a pain in the ass for any other carrier.
The problem is the Verizon's firmware itself, for example, even the non-US devices (XT860, XT883... you name it) are listed by "cdma_solano" in the build.props, and while those files are filled with CDMA codes, there are hardly more than 6 lines of GSM related codes. So my simple tweaks does nothing to improve the signal (tested/proven).

Indeed this is the only reasonable explanation, the same behavior in five ROMs can't be a bug.

Maybe is omething hardcoded in the libril or whatever in the userland, surely is not the radio itself.
XT883 is not affected, so we should try to replace some piece to spot the culprit, BTW this process would be easier when the bootstrap will be fixed to work on XT883, (why doesn't work on that rom is a another nice mystery).

Indeed, a GSM ROM would be great

FYI, audio and video codec issues are being addressed in my next build of CM7.
I'm going to give the GSM ROM a test drive and see how the CDMA stuff is affected. As well as look at the differences by file.
Hopefully, i can incorporate coreless88's changes back into the main ROM so that we don't end up with 2 CM7 ROMs (CDMA and GSM).

911 and e911 explained

Personal background: Associate degree in Laser Electro Optics. 12 years research and development semiconductor manufacturing, 15 years as an EMT, last 10 years as a 911 telecommunicator for Austin-Travis County Emergency Medical Services. 6 of those years as a Training Officer.
The reason for my (cough) resume is so everyone understands I have the technical background and experience to explain the differences between e911 and 911.
Public Safety Answering Point: the local organization tasked with answering emergency request phone calls and dispatching appropriate emergency resources. PSAP's are broken into two types, primary and secondary. The primary PSAP is typically the local police department for city's and the local sheriff's department for unincorporated areas. Some colleges have their own police department and may have their own PSAP. So realistically a person can connect to a different 911 call center depending upon their location within a small geographic area.
Large urban areas typically have secondary PSAP's. The secondary PSAP usually consists of public safety departments not related to law enforcement such as fire and/or emergency medical services (ambulance services) specially trained to send request specific resources dependent upon the emergency. In Austin and Travis County we run 120 thousand EMS 911 calls per year. The police department takes about 2000 911 calls per day.
911: a simple to remember phone number nation wide allowing everyone access to emergency services. No location information is transmitted or received. The PSAP is responsible for determining location by interrogation of the caller. This can a problem if the caller is altered or otherwise unable to give accurate information.
e911: Enhanced 911 was created to ensure location information was transmitted to the 911 call center regardless of the callers ability to give this information. The phone companies are responsible for ensuring this information is available and transmitted to the PSAP. Conventional e911 is effective for landline phones. Cell phones present a completely different problem.
Cell phones are required to meet two different location technology standards.
Phase 1 wireless data: as cell phone use skyrocketed in the nineties, legislation was passed requiring provider's to transmit location data based on the cell phone tower that the cell phone was connected to. While this is helpful, it is problematic due to the sheer size of the area that had to be searched if the caller was unable to give their location.
Phase 2 wireless data: legislation now requires GPS location data be provided by the cell phone company. This location information can be transmitted via the gps chip from the cell phone or via radio location triangulation using the cell towers in the immediate area of the caller.
So in a nut shell, my test of neobuddy's ICS indicated that 911 worked for a sim loaded phone. I did not test the phone with the sim pulled. I also did NOT verify that GPS data was being received by the PSAP.
If 911 works with your phone it should work in any area. I was connecting with two different PSAP's as I live right between two different area's and sometimes connect to one or the other.
Hope this clears some of the confusion. A good explanation is located at en.wikipedia.org/wiki/Enhanced_9-1-1.

Developers should also note that as technology continues to advance, video conferencing and text message 911 activation requirements will also be legislated in.
I firmly believe that Google should begin requiring manufacturers make their modem software and audio software open source. Manufacturers should also be required to provide detailed explanations of how the relevant library's interface with the operating system, modems and audio system when activating an emergency call. This is Androids achilles heel. All it will take is one national media event to slam the door on open source operating systems for cell phones. I love the freedom Android provides and the exceptional programing skilss of our developers.

Im sorry, while this is a great explanation, i really didnt get the bottom line....
What we have on nonsamsung roms then is just a plain 911 incapable of transmitting location?

CM7 with WORKING 911 (oh yeah, GPS works too and is VERY fast to lock. Insanely so in fact -- pretty much identical to what you expect with the LG Optimus! Those who say the GPS is broken in the hardware in these phones -- you're wrong.)
No support available at this point from me since the original source for the replaced bits hasn't been disclosed. Had there been some documentation on where the original source for those bits came from I bet this would have been fixed a lot faster. If that is disclosed in the future I'll consider supporting it, but for those who want it, here it is.
Incidentally it works on CM9 too.

I just downloaded your kang and running great so far, Thanks for you work !!
Question, is this 911 fix kernel dependent ? ie will it break if I flash another cm7 kernel ?
Thanks again for your hard work !!!

will replacing the kernel break both 911 and gps fixes?

I didn't save anything.
Here's the bottom line, if you're interested in it.
In the original Vibrant device directory there was a set of sources for libaudio -- one of the shared libraries that Android depends on to talk to the audio hardware in the phone. There was no documentation as to where this source came from, but I know where it didn't come from -- it didn't come from a public Gingerbread source for the Vibrant, because there isn't one.
It turns out the library this source builds does not work correctly but exactly why I'm not certain of. One of the problems with debugging this is that I have to have someone else test for me, which means I can't do the sort of testing I like to when I'm tracing things like this (a highly-iterative process that requires that I actually be staring at the debugging screen while doing the deeds that cause the bad behavior) since I can't call 911 myself.. Had the provenance of this code been documented originally (or lack thereof) I would have investigated this possible connection, as I knew the problem lay in the audio connectivity due to myriad kernel and application traces a couple of months ago. I didn't chase that library down and attempt to graft in other related versions because I assumed that the CM people knew what they were doing building that library from source rather than using a cribbed copy from, for example, Froyo or a different gingerbread build off a similar device.
Picking up a different shared library does work. Exactly what the provenance of that library is (e.g. was it grabbed from a binary, was it built from DIFFERENT source, where did it come from?) is also unknown.
Now that I have a working shared library on this device and a non-working one I'm going to compare traces. Maybe I'll get lucky and find the changes necessary in the source that's in the build tree and be able to fix that, at which point I'll know what I've got rather than having a "magic" library from God-knows-where.
Now here's the part that annoys me -- I was all over some of the CM guys about audio problems with other Samsung devices and tried to get access to the "not yet finished" repos because I expected that if I could run down the same sort of problem with ordinary calls in one of the OTHER Samsungs it was rather more likely than not that the same fix would be pertinent in some way on the Vibrant -- simply because manufacturers tend to use the same chipsets and bits, along with APIs, between different devices (it makes it easier for their coders and maintainers to do their jobs.) In addition when I started working one this one of the other protagonists didn't give me jack and crap about the provenance of anything in the device tree and, again, there's no docs embedded in the tree either. You can find the flamewar and slander aimed at me here if you'd like. It turns out I was on the right path; the problem this library allegedly fixed was having to hit <MUTE> twice to turn off and on the audio path. Sound familiar? Well, the pointer to the file that I found and integrated was from a bug logged against the I-9000, a similar phone to the Vibrant, and that library version works. What's changed in it? There's no set of commits logged against the ZIP file provided in that patch; is it a binary lift from a different build (e.g. some factory build) or did someone fix the source?
Who the hell knows because again, it's not documented in the bugtracker. Until I know where it came from and, if there's source, I have access to it, I won't support it. I don't play the "hide the sausage" game when it comes to alleged community coding projects.
I ran into something similar with the Triumph in that there was a different set of parameters coming up from the hardware when a wired headset was plugged in. That was easy to run down because I could do it and see what was going on; it was a literal couple of line change in the code once I found it. There are a couple of places in the libaudio source that might be the cause of this now that I have a reason to look in there, but without being able to easily reproduce the condition that creates the failure (e.g. call 911) it's a guess.
The ICS builds out at present have a different copy of the same compiled library and it also works. I bet that one works too on CM7 as it's fairly close to the metal and thus the API's probably the same (or close) on the Android side but I haven't tried it yet. I've got little reason to since I now have a libaudio.so that's functional on CM7 in any event.
While I've been working on the 911 issue (for a couple months on and off) I also traced down some actual working (properly) GPS libraries that handle the AGPS assist data in the correct way, something that other sets of them do not, and added those too. I also made a few other changes. The battery life is reported to be rather impressive, and the near-instant GPS locks most-definitely are. I can't speak much to the battery life view of the world as of yet but I will be looking at that; that's an area I know quite a bit about (getting these devices to properly go into deep sleep as they should) and the source tree I'm working with does have kernel source.
Any sideloaded kernel that leaves libaudio.so alone (check the zip file to make sure that /system/lib/libaudio.so is NOT present) should be ok, but no promises. Before you go screwing with kernels make sure you want to --you might break GPS performance as a number of the kernels have various attempts to get the GPS to work right and load various libraries along with the kernel itself with varying degrees of success.
I'd be willing to maintain this port but there are two conditions -- first, I expect apologies from the CM people who attacked me, in public, and second, I expect a formal commitment that there will be no more hiding of information. "I don't know" is an acceptable answer provided you run down the person who does -- someone does know because someone DID either import or code the material in question; silence and lack of documenting where things came from and how they came to be is not acceptable. When things go into the codebase through review they damn well ought to be documented. I played "talking to the brick wall" with the Triumph and now the Vibrant and I won't do it if I'm taking on responsibility for maintaining something.
If CM wants me involved in this that's the deal. If not I'll consider setting up a parallel build and set of repos for the bits that have to be changed from the base CM7 Gingerbread branch as I did for the Triumph if there are people interested in it, but my time is not unlimited and in all honesty my taste for working with the CM people and the CM code in general has been seriously damaged, never mind that what I have here seems to work just fine. As such the benefits of continued efforts are likely to be relatively small. If I decide against a continuing effort I will take the build environment that produced that I have now and attempt to set up a manifest so it can be cloned by anyone else who cares to do so, which should take care of others being able to build and run the KANGs from source if they wish. The latter may take a while as I need to find a day when I'm not busy and can put that together (again, lack of documentation doesn't help) and then pull a clean test from a zero base and make sure it builds and runs.
The Vibrant is no longer my daily device but I do still own one, and given its relatively modest resale value I'll probably keep it as a spare device -- it's a very credible phone and with working GPS code it actually locks faster and better than my Hercules does. It's biggest shortcoming is that it's relatively RAM-starved compared to more-modern devices.
Fancy that.

[Q] No 3g with CM 10.1 plus some other less severe issues

Greetings,
Just a few days ago I installed the most recent CM 10.1 nightly, first 20130319 and now updated to 20130323. For the most part, my phone is working well, but I do not have any 3g data service nor have I had it since installing CM 10.1.
I have a Droid 3 XT862 being used in the US on Verizon's CDMA network and placing and receiving calls works. I *can* send and receive SMS as well, although in a test I did toay I sent very short 25 character text from my Droid 3 on the Verizon network to another Android device on the Sprint network and it arrived a mere 2h15m later.
I have read many messages on this forum and others, but either the problem addressed is too far removed or the ideas/changes suggested are offered with little explantion as to why, so I am unsure if making any of these changes would be a good idea. I did read through the build.prop on my device and it certainly appears that it is more or less configured and ready for CDMA usage. I have performed a *228 PRL update, but it did not appear to help. CM 10.1 makes available, unlike the stock ROM, a menu/page full of mobile network settings. I have tried to work with some of these settings, toggles, preferred network types, and so on, but again none of these changes seems to have had an effect on my 3g data connection.
Am I doing something wrong? Does anybody know how to fix this? Or perhaps it is a new/temporary bug in CM 10.1?
As for the operation of everything else under CM 10.1, I like it very much. It is a very big step up from before, when I was first using stock Android 2.3.4 followed by the Maverick ROM, which, while better, sure liked to crash/reboot when under memory pressure. I do have a few issues that I hope others might be able to help with:
* The hardware keyboard's ALT key does not appear to work anymore which rules out half the symbols on the keyboard, making it far less useful. I also cannot use it any longer with VX ConnectBot as some of the mappings do not seem to work. For example, the "OK" key used to work as a CTRL key. Maybe these are related? Any idea how to fix this?
* The backlight on the hard buttons and on the keyboard was, previously, triggered by a light sensor (I think). Now the backlight comes on when there is any tapping, swiping, or button/key activity. That's fine, except that the timeout for the light is extremely short, on the order of about two seconds. In a dark environment, this can be annoying.
* It's slow... my god is it slow! I think this is due almost entirely to a severe lack of free RAM on the device, but I don't know what to do about it. Some programs, like GMail, take forever to start, while many others are just very slow to use/respond. I see the "Not Responding" popup appear *much* more than ever before, but, as I know these apps are just slow and not dead, I always just tap on "wait" and go on with what I was doing.
I really don't think I have that much running in the background or foreground to use all of this RAM. I have replaced Trebuchet with NemusLauncher in hopes of freeing some memory. I have three widgets only: a clock/weather widget, the standard calendar widget, and the Google Voice inbox widget. In the background, besides whatever Android and CM run, I have Google Voice and imo (the instant messanger) running. I believe that is it. Is there *anything* I can do to improve the speed issue? I understand how Android handles memory, so it is clearly not about just increasing the "free RAM" value. That said, however, it seems that if there were fewer apps trying to use the limited memory then this would naturally be higher to begin with.
I have a decent collection of apps, but the number is much smaller than in the past and most all of them should remain dormant unless I actually run them... or so I believe.
Okay, so those are the issues. I could add battery life and the camera to that list, but I have read on the forum that, no thanks to Motorola, the camera is unlikely to be available anytime soon, and I have also read that the battery issues should be resolved soon.
So, um... please help! And great many thanks to all of the hard working devs who bring us better software and especially to those who help those of us with devices that are practically *new* and yet abandoned by the carriers. Extra kudos to those finding ways to work around locked bootloaders and proprietary binary blobs.

Can you force it to EVDO only? And what happens in a stock ROM?

In the mobile network settings page, as mentioned above, I can, and have, tried many of the options. Among them is the preferred network type.
It defaults to 'global' which actually sets it to LTE/CDMA, though this is not an LTE device. I have tried all of the options that make sense (i.e. nothing GSM related). I have tried Evdo-only and currently have it set to 'CDMA/Evdo auto'.
None of these settings has changed anything. To test, I disable WiFi and see if I have a Net connection.
With the stock ROM, as well as the Maverick ROM, when I have 3g, the letters '3g' appear in the status bar next to the mobile signal strength icon and there are two small arrows to indicate I/O. This is what I expected to happen with CM.

I have a 3g update, but no solution yet.
In the mobile net settings page I have the network set to 'CDMA/EvDo auto'. Then I turn on airplane mode to force the radio off, then turn airplane mode back off.
The radio comes back and as it does I can see the network strength icon briefly add an R, presumably meaning reconnecting, followed by a 1x, and finally by a 3g. Then the 3g disappears. This entire sequence takes only about 3 to 5 seconds. If I do this while viewing Settings->About->Phone, I can see the current radio/network states change. Of course, I do all of this with my local wifi connection off.
Also, I did try a network type of 'EvDo only' and the above sequence still occurred but without the 1x step. However, this sequence didn't seem to occur as reliably as when the network is set to 'CDMA/EvDo auto'. For reference, the phone info page under settings indicates that this phone or network is 'CDMA - EvDo rev. A:6'.
So, it would seem 3g is at least possible, if fleeting. What should I do now? I really don't want to stop using CM 10.1.

Same issue here. No 3g. In the system status, it will briefly show the mobile network status as "connecting" then drop back to disconnected.

If you reboot into stock it works right?

Me or rocksolid99?
In my case, I, well, did not follow the correct Safestrap update procedure when I went from 1.x to 3.05. As such, I *think* my stock ROM may be slightly hosed. I *do* have a complete backup of the original stock that I created with Safestrap 1.x, but 3.05 does not "see" it when I tap on the "Restore" button in recovery. So, I have it, I'm just not sure what I should do if I really need to restore that backup.
However, I have installed the Minimoto 1.7 ROM into slot 2 in Safestrap 3.05 and if I use that ROM (which is a super stripped down Droid 3 stock) then 3g works just fine. I did not have any network/connection issues and did not need to take any extra steps to get 3g to work.

I'm pretty sure data has not worked in cm10.1 since 3/11 build.

Really? Good to know. Thanks for the info.
If I might reiterate on my other CM 10.1 problem, they keyboard? Right now, the ALT key does not work which means that I cannot access most of the punctuation keys. Strangely, in many apps when I press ALT I will see the cursor change with the upside down triangle at the top of the cursor bar indicating that ALT has been pressed. Good, but if I press any other key it is not recognized. It is as though I had not pressed anything. The ALT indicator doesn't even change or go away. The only thing I can do is continue to press the ALT key to cycle through its states (off, one-key, locked). Could this also be a bug in CM 10.1?
Is there a better or more correct location to submit these issues? Since these issues are/may be bugs in CM 10.1, should I not submit a bug report directly?
Beyond the 3g/data and keyboard issue is the RAM usage. It uses a *lot* of RAM. Is this just the way it is? The Droid 3 lacks enough RAM to really make a serious go at Android 4.2?
Thanks again!

As a matter of fact, there is: http://androidhosting.org:8050/projects/device-motorola-droid-3-xt862
Hashcode tweeted that last night...

When Motorola hinted that this was the reason why the D3 and X2 would not get ICS, nobody believed them.
I think it's pretty clear that CM on the Droid 3 at the moment is alpha/beta status. If you want stability and full features, you need a Gingerbread ROM. Minimoto is best for me.

+1 anything above gingerbread is not stable. Some people manage to use them for daily drivers but they have to deal with the bugs. Myself, I need a camera and I need my phone to work all day, I use it for my job. As such, I run minimoto, as it is quite stable, and any bugs that do arise can be dealt with as it's based on gingerbread, which is stable on our devices. Liberty is also a good rom to use, it's based on an older system version but it's quite stable and has lots of features, as opposed to Minimotos minimalist goal.

has anyone tried making a swap partition for cm10.1 ?
I made it and it seems to be much much faster or the latest nightly (04/07/2013) is quicker.
anyhow I have it up only for about an hour it remains to be seen during the day how it's reacting
regards

Have you (or has anyone) successfully booted CM10.1 on the XT860? I just get bootloops after install. MiniMoto has been working great for me though.
