CDMA Roms?

I have searched this forum for a CDMA rom but I cannot seem to find any. Is their a different process for flashing a new rom to CDMA phones. A link with information to flashing CDMA Touch Pro 2's would be delightful. Thanks. Also will my MMS/Data settings be erased and need to be typed back in once I flash a new room

They have a whole CDMA Upgrade forum over there.

Help needed for CDMA data service (downgrading from 4.4.2 to lower version)

I have a Samsung Galaxy S3 SCH-I535 CDMA Verizon & GSM phone. Originally it was on android 4.1.2 and working fine for both CDMA and GSM (one at a time). CDMA EVDO Rev A data service was working fine.
I am using this phone in Nepal (not in USA). It was carrier unlocked for both CDMA & GSM when I purchased from Amazon. (so, I guess, Originally it may had some customized firmware/ROM for International use, I don’t have much idea).
I was asked for firmware upgrade every time when I run Samsung Kies. One day I clicked to upgrade the firmware. The upgrade was over successfully. But the new android version I found on my phone was 4.4.2.
In this version /new upgrade, I was unable to use CDMA data (EVDO-rev A). So I wanted to reverse back to old version. I search the process in Google and tried to load firmware with the help of Odin3 using this file:- “I535VRBMF1_I535VZWBMF1_VZW.zip”, but it was not successful. Result: Fail(Auth)
Then I loaded firmware for 4.4.2 using Odin3.09 (AP: “I535VRUDNE1_I535VZWDNE1_I535VRUDNE1_HOME.tar.md5”) and now the phone is working.
• If I use GSM SIM I can make call and use HSPA data service as well by adding new APN.
• If I use CDMA RUIM I can make call, BUT DATA SEVRICE using CDMA EVDO Rev A is NOT WORKING!! (I can not save APN in this case).
Now my issue is how to make CDMA EVDO data service working in my phone, because my basic requirement is to use this phone for CDMA service (voice + data).
I can edit the APN but when I click “Save”, nothing was saved. So I can not select APN for my carrier. I tried using APN Manager Pro too, here I can enter & enable the APN, but did not work. The phone is not able to dial the data access code #777 (verified from CDMA service provider side trace).
Can someone help me what I should do to make my phone working for CDMA data. My phone is rooted.
I guess it may work for CDMA data if I downgrade it to 4.3 or 4.1.2,
Can I do that. If so what are the procedures / steps. Any help in this regard would be highly appreciable.

My data worked this way

I think your problem is the region is not set Nepal...I installed dark jb rom in my phone and data was gone since then. Then I manually downloaded stock firmware and flashed through odin but still data wasnt working,nd while in recovery mode i saw region INS ie India. then something came in my mind and.. .I changed it to NPL and now i can use data in only sim 1 only not in both sims. So i also may need some help.
For you *#272*IMEI# . Use your phones IMEI number there (*#06#) . Select NPL region.
NOTE: It will hard format your phone installing required carrier apps, aps, bla bla and hope work on your phone

I found that the hidden menu (& hence secret code dialing) was disabled in my phone. Following guides from Google search I enabled it. Now codes likes "*#06#",*#1111#", "*#0228#" etc are working, but "*#272*IMEI#" is not working. Any idea, why it is not working?

Well, it looks to me as though you've locked your bootloader and are now stuck on 4.4.2. For some reason, Verizon forces Samsung to lock their bootloaders, which means we (the consumers) cannot install "custom" firmware on our devices (or downgrade).

Once you're on 4.4.2 NE1 your stuck with it. No downgrade possible at least not without a Jtag service

hi i have been using Verizon htc one m8 in india on gsm network for an year now. As the 4g Lte services are launched in my country i got to know my phone does not support the required band. I just want to know the process to add Lte band 40 2300MHz to verizon htc one m8. my htc m8 is S-0ff on SD V10.1 rom thanks in advance.

I would believe that it would work using those links and the guide in it. Concern would be is the author of it clearly States enabling extra bands may break phone to point of RUU won't fix it. I can tell you on my Verizon m8 when I first used the DFS tool I had 4 Lt bands enabled, believe is was 2,4, 12 and maybe one more. So 3 or 4. I have it on T-Mobile sim, so. Was enabling 6 bands, at least 2 more then before. My first try I accidentally hit band 40 also so I was turning all T-Mobile bands on and a extra one. Now that didnt fry my radios. Noticed it on the first text to check if it worked. I'll write why I did, I think enabling just that one band won't kill it. Also if a band is active and you don't use it, maybe turn that off and 40 on. Okay heres my step by step guide it did.:
1. Downloaded DFS TOOl , free version is fine just takes extra time that's all.
2. Using command prompt., did the adb shell, then su, phone will ask for approval for supersu access. Then enter the code to turn hdiag on. You want to use the one for m8, first codes are for m9 , the m8 is clearly said in bold. Once entered to turn in on. Plug in your phone. Now run DFS with administrative rights, can't remember what the exact steps for the next things but just follow the guide. In DFS tool you should see your phone connect , not in usb mode, but cm 8 port, cm 7port. Now for the computer to read the phone in DIAG you need the driver, its in the m8 HTC sync manager thing. So if that's installed you have it already. Now if it's installed and you don't see it recognised in diag mode using device manager option your PC (by the way I'm running WIN 10 on my PC) I had read that I'm windows 8 it would not accept drivers without signatures. There is a guide in there explaining how to install under that. My phone was not picked up in DIAG mode, had sync manager , driver installed from DFS tool, then used a zip I'm authors guide. Unzipped folder and it was broken into folders. Have to find folder with exe to run it. After all this still no dice. Then went to device manager , went to phone where it stated driver missing. Douple clicked on it. Chose option to update driver, selected in there a option that will show you all the drivers installed on the device. Chose the HTCDIAGDRIVER. It installed it and had to reboot comp.
3. Now go back to DFS TOOL., follow the authors guide to the T in this process. You pick the last tab , LTE , I believe. Following guide, I let it read all my lte bands, wrote down all the current ones in case I needed to change it in time. Then chose to read again and write down LTE bands using authors guide, of the selection in bottom right of screen u need to chose. In guide it States the name of it, and to choose that and read. In that option In bottom right, there is another selection next to it, 3 of 4 same words can't remember the word but its in Authors guide. Now your gonna want to have what bands are currently enabled, in authors guide is what LTE bands should be choose by manufacturers default. I then choose the bands it had listed that should be, and deselected any bands that where not being used on current provider. Now you want to hit write after choosing your bands. Now after that you want to write the bands in next mode that author says to change just in case. OK, now you can't do both writes at same time. If you do, first write won't stick and only second. I tried and can tell you that. So write , reboot, write, reboot. Now after that, reconnect phone to PC and read both things you just changed to make sure they stuck.
4. Using command prompt on PC, adb shell, su , then code to turn the hdiag mode off. If you don't PC won't recognize the phone as prober driver and a DIAG mode. Make sure to do this.
That's what I did. I would advise to read all ten pages of former questions, lost of newer information that will only help you understand it more.
I'm far from a expert, I just know the adb commamd process, how to flash ROMs, mostly basic things. 4 Years ago I knew nothing. So I'm sure u can do it. Author will answer questions, mostly every question you can think of has been asked in those ten oahes and you will learn it from there. So i would read all posts so you have a good feel of it. Anything I can help you with write back. Havent been on in two weeks. Stock market has my attention 18hrs a day

Updating & Unlocking Sprint LG G Flex 2 (LS996)

I purchased a brand new LG G Flex 2 and It dawned on me that it was a Sprint variant LS996, rooted and unlocked. I do not live in the US and the phone is working fine with my local carrier, except that there is no tethering option. It currently has Android 5.1.1 installed and software version is ZV6. Since the phone is rooted, OTA updates download but fail during installation.
Now, what I want to achieve is to update the phone to the latest software version and also retain the carrier unlock. I would be thankful if someone can point me in the right direction. It would also be nice if I am able to make a full backup of my system in its current state so I can revert if things don't well.
Thanks

I am in the same situation with my LG g flex 2, there is no hotspot option.

Follow my back to stock guide with stock images on general section. That should help you to go unroot pretty easy and then ota update. Read through that forum there are several suggestions you may apply too.

Thanks for your reply. From what I understand, I have to flash stock ZV6, OTA update to ZV9, and then flash rooted ZV9. Will I lose the SIM unlock in the process? I have seen some people on another forum claim that they went through this process without losing the SIM unlock. On an another note, I managed to enable tethering by changing network mode to Lab in the LTE settings hidden menu. This also disabled the annoying Hands Free Activation screen. However, the Wi-Fi tethering is limited to 1 user. I tried the suggestion of changing SPR to GLOBAL in build.prop, but I couldn't save the file if I added anymore than three characters in place of SPR. I also tried adding dun to APN type in the LTE settings menu, but found out that APN type is not editable.
