[Q] CM7 and GSM settings: Can someone put it all together? - Verizon Droid Incredible 2

I read in the Development forum several threads that address partially how to get your Dinc2 to use GSM (even AT&T here in the US). The problem is that no-one has put a cohesive set of steps together to make it clear how to do this with a CM7 ROM. Even our "master developer" attn1 insists that it should be possible to use the phone with GSM. But I found:
a method to change settings inside the phone *#*#4636#*#*
someone mentioned to switch to GSM only with 2G checked
someone mentioned to use global setting
someone mentioned to use GSM/WCDMA auto and not prefered
and someone mentioned to use GSM/WCDMA prefered.
And then there were several iterations with reboot or turn off/turn on, or not.
But non of it seems to work consistently, something I not only notice now (back in the USA) but also while I was in Panama and Chile.
Can someone put a succinct set of steps together that is fail safe and works?
Thanks!

[Q] Network settings

Hi all developers! I have one question - have anyone information about where home network information placed? As I see radio settings is independent from ROM settings. Also I see that some settings placed in ROM, for example Call section's NBPCD and Assisted Dialing settings. Problem is that I use Incredible outside from U.S. and some programs wouldn't work fine because it have some limitations in US - for example new Skype work only in WiFi mode. Then I try to run it in 3G network it's write attention like "In the United States you can only make Skype calls over WiFi". Can we fix it?
P.S. changing NBPCD and Assisted Dialing settings give result only for call making process, not for global network settings.
P.P.S. I found one way - we can change file build.prop in ROM image (system/build.prop). There is two sections - ro.cdma.home.operator.numeric and ro.cdma.home.operator.alpha. I change it to my operator's default settings and bingo, I have stock Skype.apk, that work in 3G network. Next step is change stock's backup image. So, have anybody information about OS files, where this information placed?
Last update - simplest way for change build.prop at installed image is SDK's adb pull and adb push commands use. It's checked and really worked.

I thought I had read somewhere that verizon is letting Skype work over 3G. If I can find it again, I'll post it here.
Found a hacked APK over at DroidForums. I'll try to post the link.

WCDMA / GSM auto problem

Hello Guys,
I'm experiencing a problem with my Froyo Desire for probably a week now.
The thing is that in certain areas my Phone can not receive calls / sms or such. In other words "GSM services" dont work. 3g though works fine (stable, strong and fast connection) My Provider is T-Mobile.
After quite a lot of testing I was able to isolate the error:
When WCDMA / GSM is chosen by the phone automatically it seems to me as if it didnt switch "back" to register with my provider via GSM when i want to make a call or if someone wants to call me.
When i switch to "GSM only" manually everything works fine but i have no 3g of course.
I also experience this problem only in certain areas. I live in an area where there is really strong HSDPA available (up to 7mbit\s). When i go to other places of my city i still get HSDPA (not as strong) but calls / sms still work.
The last paragraph may be of no importance, i don know.. probably it helps..
I have googled quite much about this problem and also found a few persons experiencing the same issue but nobody was able to come up with a solution.
I would be very thankful if someone could try to figure this out.

Hi Guys,

gsm only Desire?
I'm having a nightmare with 3g 2g connectivity on my Desire on the three network whilst at home. If I could manually select gsm only this would be fine as I could still call and text and use wi-fi. Unfortunately my options are gsm/wcdpa (or whatever) auto or the 3g only.
can someone please advise if it is possible to select gsm only and if so, how?
many thanks
Can someone please advise me how if possible, to set the desire to gsm only?

Wireless and network-Mobile network- should be here somewhere.
Thanks, but there is no option for gsm only. It's wcdma only or gsm/wcdma auto. there has to be a way around this.
Similar problem, different version
I've experienced similar problem.
In some area, I can get steady grps signal when I switched GSM only on; but when I switched WCDMA/GSM on, I could get no data connection at all.
I'm using China Unicom's mobile service.
Solution
Hi there,
I've the same issue and I fix it allowing the option GSM/WCDMA Auto in the configuration menu.
Then enter the following code *#*#4636#*#*, select "phone Information" and set preferred network type, set "GSM car (PRL)".
Sorry about my bad english.

CDMA not working

I'm afraid my CDMA radio is broken. (At home my LTE signal isn't strong enough.)
I only used it half a day before sending my Verizon HTC One to Colorodo for S-OFF. The signal then seemed fine. I didn't set it up until i got a case for it yesterday. First i installed the GPE by newtoroot (because it was smallest to download) and everything seemed fine but i honestly don't remember, then installed the other 2 custom roms both only giving me LTE only.
Things i've tired so far that haven't worked:
1. I restored my nandroid of the Stock, but got the same thing.
2. I've tried all the custom roms but still can't get CDMA to connect.
3. I tried the RUU, (since a few parts of it are corrupt, i had to leave out system and recovery) then flashed a custom rom
4. I changed some settings in the ##778# menu (copying my Inc 4g)
5. I've installed LTE on off to easily change radio options.
6. I've tried a different sim from another verizon smart phone line
I've also tried combinations of those, but still have not gotten my CDMA to connect.
Does anyone have any other ideas for me?
Also, if someone doesn't mind giving me their settings in the EPST menu (##778# then edit mode) for CDMA Settings, and Modem Settings, I'd appreciate it.
Here's the CDMA and Modem info from my EPST menu. I'm not rooted or S-OFF though so I'm not sure if there will be a difference.
CDMA:
A-Sys Primary: 283
B-Sys Primary: 384
A-Sys Secondary: 691
B-Sys Secondary: 777
MOB_TERM_FOR_HOME: Enable
MOB_TERM_FOR_SID: Enable
MOB_TERM_FOR_NID: Enable
EVRC Enabled: Enable
Home Page: EVRC
Home Orig: EVRC
Roam Orig: EVRC
MODEM:
Slot Cycle Index: 2
Preferred Serving System: Automatic
Preferred Mode: Automatic
HDR Hybrid Preferred: Enable
Clear All MRU Entry: No
Rev. A: eHRPD
1X Diversity: Disable
Good luck! :good:
ok, now i'm getting 3g (CDMA) so i feel like it might not be a broken radio, but it does tell me that i'm roaming and when i make a call I get verizon wanting me to enter a credit card. When i switch to 4g it doesn't tell me that i'm roaming but when I make a call then it immediately disconnects and data works fine (I think verizon still uses CDMA for voice).
I would much appreciate another favor if someone doesn't mind giving me their settings in the EPST menu (##778# then edit mode) for Home SID/ NID

#1 is 26392/65535
all the rest are 0/0
hope this helps.
My Home SID/NID #1 says 73/65535
I'm thinking that and the A-Sys/B-Sys numbers are by region which might be why your phone thinks you're roaming.

Mine said 2004/65535
but that doesn't seem to help anyway.
What did help was changing my prl to an older version, but i'm still not entirely sure what happened and why my phone messed up like it did.
I was able to fixed my problem with the newest decripted ruu from zarboz found here
once i ruu'ed i turned off fast boot in power settings and i turned on gps then i did 2 factory resets. 1 from the rom and 1 from the bootloader.
edit. sorry if i duplicated post in other threads, i just hope when someone else has the problem then it's easy to find and fix.

Setting up uk m8 for t-mobile trouble

Hi,
I opened another thread regarding safest method to change from unlocked stock os to the T-Mobile release for Wi-Fi calling, possibly in wrong area as somewhat related to T-Mobile, however my main worry is ensuring I will have full 4g/LTE support, I am awaiting a sim card of a T-Mobile mvno, but I've seen several places I'd likely not be able to even use 3g without enabling the bands required, I've come across various guides .
Several said to use ##3424# or something alike(I'm out right now so can't confirm) to get into diagnostics, this does not work, I can however use the *#*#3424#*#*(again might be incorrect code) however this is self check options and to calibrate vibration etc, unable to connect with qpst with this.
Any help would be helpful, I purchased the phone second hand unlocked to use when I visit the US, I know it's unlocked and works in UK, just require it for use in US as I use an m9 as my main phone.
Would be nice to get the Wi-Fi calling function but not important.
Any help on how to go about this would be great.
Regards,
V4mpire

[GUIDE] [AT&T Z999] Unlock hidden GSM & LTE bands for international use

Hello.
AT&T has disabled all the international GSM\LTE bands on Z999, making it unusable outside of USA (at least in countries with GSM 900\1800, UMTS 2100 & LTE B3 & B20, like the one I live in). In order to change that, we need to turn on the Qualcomm USB Diag port, and for this, the phone has to be rooted.
I've been trying to root my AT&T Z999 for some time now, without any success, unfortunately. However, searching forums after forums, sites after sites, I've discovered the surprisingly easy method of turning on the Diag port without root.
It appears, that Axon M shares a lot with Axon 7, at least the secret key combination to enter Factory Test Mode:
Turn off the phone
Press and hold Power + Vol DOWN buttons until you see the screen "FTM" (see attached screenshot)
You have to press both buttons for the long time, do not release them when the phone starts - just wait until you see the screen. And that's it - you are now in Factory Test Mode and PC sees your phone as "ZTE Handset Diagnostic Interface (COMxx)"
Now, in order to change the bands, you have to follow these guides one after one:
Backup IMEI and NVRAM (ignore all the steps to turn Diag port on, you've done that already)
Unlock LTE bands
Mod edit: Link removed! (this guide in in Russian, but all screenshots are in English & every step is pretty clear)
You would need this tool also.
Please remember, these things are complex, and require considerable experience with Android & Windows. DO NOT START unless you feel confident that you know, what you're doing. I'm serious. Do not try this, if you're not experienced.​
WBR,
Draco.
Why mods deleted the link? Google translate exists.
Edit:
I've managed to get the data from the phone using QXDM.
lte_bc_config contained the value of "2251800618993690" now I'm parsing the info how to edit this. Seems like the tutorials don't really match this device. Now I wonder if the chipset can handle invalid data and just input all 1's. Unsupported frequencies just won't work.
Edit2: Writing all 1's didn't work.
Edit3: I wrote this value: "2251802901219551" Calculated with CDMATool. But it seems like the AT&T firmware only finds edge network. I've double checked the bands to be correct ones. So now I will switch to the chinese firmware.
Edit4: Final edit. Turns out you cannot flash chinese firmware on AT&T device. Sigh so my unit is stuck to EDGE/wifi only.

can you repost the 3rd link?
I can't "repost" the 3rd link, but I can suggest you to open the well-known (and the best) Russian web-site with the name starting with "4" (and having something like "...pda" also), and then add this to the address: /forum/index.php?showtopic=546814&st=4640#entry35702698
Well that russian site has pretty good instructions on how to do it. I tried with one program and it didn't work on AT&T ZTE. I'll try with that qualcomm app again this weekend but if I remember right the last time it had trouble writing because it had no correct service mode code \o/

that website's address ends with ".RU", doesnt it?
i accessed that website as your given link, but i cannot see any related threads about ZTE on that, seems all they disscussed about is Lenovo K910SS. was something wrong with my searching?

Every Quallcomm device has almost the same NVram configuration rules, the difference is usually on how to enable diagnostic port, but for Z999 I have figured that out already. So, for the configuration process, every Quallcomm guide should work.
I've successfully enabled Z999 to work with 2G & Edge in my country using these guides. 3G & LTE don't work yet, but I'm sure they will eventually. I don't believe Z999 lacks the hardware ability to use LTE B3 & B20 (and other bands), it has to be something wrong with NVram parameters.
For me 2G and Edge worked out of the box in Finland. Tried to enable more but only thing that changed was power usage. Not worth it

It means success unlock 2G/EDGE, not yet with 3G and LTE? When buy the device, it can use other carrer to call and 2G.
When you finger out the way to unlock LTE, please share me.
by the way, do you have the way to enter fastboot mode? I tried the "volunm + &power button" but it just do a normal restart into android.
Fair warning to everyone trying this, make sure you actually do a backup of your IMEI. I didn't and after screwing something up my SIM is no longer detected, and my IMEI is no longer available.
Hello folks!
I have an AT&T phone. I cannot connect to ANY (even EDGE) network!
I modified the configuration several times:
---
I have EDGE with this config:
00441: 0 and 0xFFFF
00946: 0 and 0x06A8
01877: 1677472
02954: 0
06828: 524356
06829: 524356
I got no LTE
---
test2:
06828: 524485
06829: 524485
I got no LTE
----
00441: 0xffff (but 0x380 is recommended)
00946: 0xff8
02954: 0 and 805765120
01877: 3460734838925427584
06828: 1904863
06829: 1904863
I got no LTE, just continous dropping network, useless config.
----
00441: 896
00946: 0 and 0x140
02954: 0 and 131072
01877: 562949974393728
Only edge network, error while searching for networks.
----
06828: 524485
06829: 524485
I have EDGE with this config, but no LTE.
----
Anyone has a good and working LTE mode?!
edit: "The bands on the AT&T z999 are: 2, 4, 5, 12, 29, 30, and 66. "
So, there won't be any Band 1,3,20 for us?!
Thanks!
No one has gotten LTE work on AT&T model. I wouldn't try this.

Have you been able to make 3G & LTE work? I just got my ZTE AXON M from ebay and since I can't use data or make calls/unlock the phone I was thinking of trying this.

Thanks !
Hello guys. I've tried all configs mentioned by @ugynok and some of my own - the result is still the same, no 2G network and all options in mobile connections are disabled not clickable. Can you please advice which config worked for you to enable 2G network?
Any luck?
Hi all. Was anyone able to get a useful set of bands working in the UK for this phone?
Many thanks.
