Ok heres the deal.
My friend sold me this Phone.
Its sch-r920. With CDMA/LTE
Has bad imei and no sim card.
I used qxpc and dfs. I can get it identified which was a pain
Until I changed usb setting to modem from pda.
Now I can connect. And it will let me change phone number
And prl lists and everything except the emei.
It says bad code. And the spc I have works.
It works on all programs.
In dfs the spc lets me read and write everything but emei.
There is no nv_bat. It has the efs folder.
I am not concerned with LTE. I just want the 3g and the phone to work.
metro wont get 4g in this area in my lifetime.
When I check engineering mode it has sp lock and net subset lock and the two others.
Are those lock just for the LTE network?
Or is that effecting my emei writing?
I went through this forum but not much on this model.
I never had a problem with cdma but this is a hybrid phone,
So its new to me.
Any help would be greatly appreciated ive been reading for a week.
I love learning more but it would be nice if someone threw me a bone.
And im not afraid of hex editing, just cannot find the file to edit.
Thank You so much for reading and feel free to pm me.
Hello, I bought a SIM card from straight talk hoping to use it on my merge because I have seen people online that says I can do that as long as i have my SIM card unlocked. But after I got the card activated and put it in my phone it don't work. I try changing to GSM and using their APN but I have no signal, the mobile network just stays unchecked and I cannot check it. After a few minutes my phone suggests switching over to global mode and i do have mobile signal then but still no connection with anything. I called the straight talk woman and she told me it only works with AT&T or T-Mobile phones but it just don't make any sense to me that you have to have one of those previous carious just to get them as a new carrier? Am I missing something here?

Thanks to the helpful people over at 2fastroms and their quick response I found out that you have to have the 1.06.00.0910 verizon radio flashed to your system. You have to install the radio in the boot-loader and not the recovery menu, it took me a minute to figure that one out. Just informing anyone that has the same problem as me because I could not find it anywhere else on the web. Anyway credit to jianC for the help.
When I go into the settings for Mobile networks at the bottom where it says System select it says change the CDMA roaming mode. the problem is I reset the phone and it now has a ST AT&T SIM card in it. Why does it still think it is CDMA?

Same exact thing happened to me. When I was researching the problem I came across this thread. The phone was showing no signal and then suddenly it received a SMS message saying my phone was ready to use. I rebooted it and it's fine, full signal. To people experiencing this, I suggesting waiting for about an hour and maybe your phone will cure itself too.
Hello all,
Back again.
I'm trying to get my "2nd" OPO to work on T-Mobile USA.
First of all, it is not a SIM issue. I have 2 microSIMs that can be used freely across all T-Mobile enabled devices.
Once I try to connect to T-Mobile, it gives me a "Your SIM card doesn't allow connection to this network".
I tried the 'unlock the basebands/LTE process', got as far as ADB talk, but I cannot execute the su command, so the setprop does not work.
And this is my 2nd phone, a replacement from OPO. 2nd month running already. The 1st one had the same issue, but at the time I did not do research on tinkering with it,
and was 'NAIVELY' believing in OPO's customer 'service'.
Took me 2 weeks just to get 2 basic replies of "tech support", which didn't help since they gave me rather weak tech suggestions - 1st suggestion was reset, 2nd suggestion
was to look at the T-Mobile thread (I cannot connect to network, so how do you expect me to connect to APN?!?) . Then took them 3 weeks to go through the RMA process,
and yet another 2 weeks to send me a replacement(not).
Any assistance appreciated.
Check your imei on the tmo compatibility site. It could be blocked. Dumber things have happened. Double check that the SIM is installed properly. Second replacement and multiple sims seems to point at something you are doing.

Thank you for your response!
Yes, the IMEI is not recognized on t-mobile. Which is stupid since this is the second one (the 1st one had the same issue too).
Has anyone else gone through this frustrating experience? To have two OPOs whose IMEIs are not recognized is...... well.... $!%#!. :silly:
SIM installations are fine. I have done them multiple times, with the same results.

Future reference no need to create a new thread to ask the same question as before. You should of just continued your first thread so others would know what you have been going through and what was done to try and fix it. Glad you got it sorted or did you....

Got it.
Unfortunately no. Second OPO, same issues again. IMEI is not supported either. So, Groundhog Day here.
I'm with you man. I left vzw for T-Mobile and struggled like hell with getting the OPO working properly on it. From loaner phones to multiple sims, they/we tried everything. End result was to leave for at& . The signal is strong, but yet I keep missing calls daily. This beauty is going up on eBay. I just can't take it anymore. Sucks because Dev involvement is Huge here
Register and activate your phone with T-Mobile... I had the same issues for MetroPCS, and that fixed it.

I dont have any issues with network on Tmo, but what do u mean by register and activate ?
What I am saying is, you need to contact your carrier and get your IMEI entered into their system in order for the phone to run all services correctly on your carrier... whether it be T-Mobile or anybody else.
My 1+1 ran most of the services and operated on my SIM card and phone number in my hometown area. But, when I went to another area or town, it would not register with or run on any carrier... NONE! not even roaming like it does at home. I had to go to MetroPCS (on T-Mo network) and get my phone activated onto their system for it to run data, and 4G LTE. By just inserting the SIM card does not automatically sign your phone into the system and you should call or go to a dealer store and get it turned onto your particular carrier to run the network correctly.
Hope this clarifies my statement.
I never had to register or the like with my OPO for t-mobile. Didn't have to with my wife's OPO either.
It's a common enough issue across carriers. Sometime you do have to register the phone, and make sure you have the correct APN settings.
I just gave my daughter my OPO, I had Consumer Cellular (ATT) SIM in it. She dropped in her T-Mobile SIM and off she went, working perfectly. She's been using the phone about 2 weeks now, and in response to your question, I just checked her aPN, since I knew it's been working perfectly for her, only to discover the phone pulled in a MetroPCS APN! It's been working so well, she doesn't want me to change it to the T-Mobile APNs that are in the list.
Here is her APN settings (Calif-San Diego area), MetroPCS
name MetroPCS LTE
apn fast.metropcs.com
MMSC http://metorpcs.mmsmvno.com/mms/wapenc
mcc 310
mnc 260
apn type default,mms,supl
apn protocol IPV4
apn roaming protocol IPV4
mvno type none

What APN is you OPO set to?
I had just popped in the SIM card and it did work in my local area. But when I went outta town, my phone wouldn't connect to any services, no roaming either. I use MetroPCS on T-Mobile network, and nothing would run without activation on their system and registering the IMEI. So, results may vary depending on the carrier or area.

registering
I am a frequent visitor to the USA from Canada. Usually with my original Samsung or Nexus rdware from Canadian carriers, but unlocked.
Each US carrier has insisted on registering my IMEI prior to activating a SIM. It seems to the user you can pull a SIM and place in any old device and most times, no problem. But that's not the carrier approved method.
T-MO was very insistent on this. To the point they would not activate a SIM for me with out the device and the IMEI first
Hopefully registering with your carrier solves this. It's a thing and may be the point of issue for you.
I apologize if this is in the wrong forum. I'm trying to help a friend out by doing a little research.
A friend's daughter has a Note 5 on Verizon. (Long story short, friend's ex husband is supposed to pay for daughter's cell phone as part of divorce agreement. He did for a few months and then skipped town. Phone was cut off.) My friend has a phone on Cricket, and was wondering if she could use the Note 5 on Cricket. The local rep tells her that she cannot, that the phones are incompatible with Cricket's network, but I'm wondering if it is just their way of trying to get her to buy a new phone.
It's not a big deal if the Internet part of the phone works (her daughter mostly uses wifi anyway), but the phone part needs to work.
I'm using a Verizon note 5 on cricket. You get 4g lte but I'm having issues with mms. Sometimes mms will work and other times it won't
Did you just put the Cricket SIM in and go, or was there anything else involved?
I put in the cricket sim card and enter the apn.
Cool. My friend is going to go to Cricket and get the SIM kit and I'll hafta punch in the APN data for her later...

I had the same issue. I do get 4G LtE in some areas but not all the time
Also, if you see the carrier it says ATT not Cricket...
UPDATE: My understanding is that ATT/Cricket works in a different LTE band than Verizon. So that might be the issue. Not sure if you can change that in a non-rooted phone.
Have anyone found a fix for the mms other than the Playstore text app fixes

Yes call cricket (dial 611) and they will set up the APN for you. I have the Sprint note 5 on cricket and all mms works. Thanks
Do you have to unlock the Sprint Note 5 or just put the sim card in
Anyone successfully get LTE working on cricket? My roommates S5 gets LTE, but I'm only getting H+ this sucks!

More than likely it's probably because Verizon's network is CDMA and Crickets network is GSM and they are incompatible with each other. You can check and see if you can switch the bands but I don't know if it's possible to do that on the Verizon phones since they're locked down so tight..

I actually got it working! This is for anyone that sees this. I entered cricket apn, then I was selecting global, and gsm. I figured those were the 2 that I needed, so I went back and forth between the 2, getting more frustrated! I finally decided screw it, and selected CDMA/LTE and low and behold!!!! The 4GLTE signal popped right up! So it is working, mms too. I'm stoked.
Edit, after further testing, calls will not work while in CDMA mode. Sucks, but I think it was too good to be true. So here's what I came up with.....toggle CDMA/LTE mode, wait for 4GLTE to pop up, once it comes on, toggle back to global mode. 4GLTE will stay enabled, until a call comes in. After your call, H+ will pop in, just toggle the CDMA/LTE, and back to global. This is the only way I've found to have constant LTE.
It seems that to enable the LTE bands, they must be enabled by toggling the CDMA on. Weird but it is what it is, especially with not having root.
