Installing I-9505 ROM on Verizon Galaxy S4 I-545

Hi All,
I know its a topic which has been addressed differently in different threads. I am a user from India and have a GSM SIM. I have got a Verizon S4 phone. I tried using it with Vodafone SIM and get a problem in using it. Surprisingly a NOTE 2 from Verizon works just fine. I am able to use it for data with 3G but not able to use it for voice. Following steps have been tried already.
- Default Options of using Global Mode and GSM/UMTS ** Doesnt search the network at all.
- Hidden Menu Changes using # codes. ** Shows network but emergency mode only.
- Phone Info app to change the mode. ** Shows network but emergency mode only.
- RF Band change using the hidden menu. ** Shows network but emergency mode only.
It does say that it has GSM radio but cant be used for some software reason I suppose. I checked with Verizon Rep and was told that it cannot be used in India with a GSM SIM and would need the Verizon SIM only to connect with International Roaming.
I was able to install Wanam Lite I-9505 ROM on the phone and patch it with Loki-Doki patch and the phone was booting. But the network signal was not getting picked up. I had data connectivity but no voice or SMS. Is it possible to patch the I-9505 radio over to I-545 and / or force it use GSM as the primary modem.

Any idea for this?

Have you messed with your APN settings? I use a I545 with T-mobile here in the states and all I had to do was change the APN settings

Unlocked GS7 Network Selection menu?

I have my GS7 unlocked. Working on AT&T Network, LTE fine. But at some point I will lose signal and then it won't connect to network until I restart the phone.
Then I noticed...I don't even have a network selection menu.
Is there a code to get to the menu manually and manually set it only connect to the gsm network modes.

Are you using the Stock G930P rom or the G930U one? Cause the G930U for what i've seen preforms the best once unlocked

Stock GH1 g930p....I didnt feel the need to flash the U version. But maybe I will.
I found an app that let me set to gsm/lte

What app?

FYI: Sprint PF1 firmware has network selection enabled, I believe it was disabled thereafter, just like hotspot and apn editing.
Anyway, the app was "Network Mode"

LG H910PR on AT&T LTE?

Hi guys:
i have looked on google etc. but can seem to find a answer. I bought a LG V20 H910PR (from claro unlocked) im using it on AT&T everything is running super fine but can't get 4G LTE only HSPA+. Is that from the phone that does not have all the bands for ATT or is there is something I need to setup?
Thanks,

Did you change your APN?

It has the NXTGENPHONE one I chaged it also to phone but still HSPA+

I will look and see if that model uses the same RSA key. If it does, then you can try flashing the entire AT&T firmware.

Your v20 supports most of att lte bands except band 17, all other should allow you to get lte with att. are you sure the apn is correct, and have you tried forcing the phone into lte mode?, use *#*#4636#*#*, if this menu does not work, download shurcutmaker from the playstore and search for network mode, that should allow you to open the network swtching menu.

Hi,
Were you able to find if the firmware can be installed?

Hi, I also have the same problem. The above mentioned code doesn't work, neither does the software you've mentioned. A bit more help will be appreciated.

Have the same problem on other operator. However if I reset the network settings and don't go into the network options it connects to 4G. If I just open the network settings, without touching anything, it locks to 3G/H+. There's no 4G option in network settings as mentioned. My APN is set up correctly. I did a bit of research and found these threads on Vietnamese forum, google translate was not helpful.

Is it safe to root/flash ROMs onto H910PR (it has V10j-CLR-PR software) using the H910 methods mentioned here?

Unfortunately I have the same issue, really disappointing. I'll try messaging the seller on aliexpress or I'll try to get in touch with the service on that Vietnamese forum I mentioned earlier. It is obviously software-side error so I am hoping this can be solved.
Also, you can go to service menu by typing *#546368#*910#.
Edit: After a bit of research I came across this thread: https://forum.xda-developers.com/lg-g3/help/lte-option-network-selection-t2827499
It is for LG G3 but the problem is the same. Basically Field test-Modem Settings-RAT selection - GSM/CDMA/LTE is a temporary fix. Other methods require root.
In the Field Test - PDP Setting - APN setting I have "LTE attach profile" which is hidden in the normal Network Settings menu. Don't know will modifying this to match my carrier's APN will change anything.

If you are still ARB 0, then you can use the H910 method. If you are ARB 1 or greater you will have to wait for the firehose method.

Hello, I am new to the site, something similar happens to me, I have an LG V20 H910, with the AT&T system it allowed me to select the 4G mode in the mobile networks option, now I changed the system for the company CLARO Puerto Rico And I don't get the 4G option in the settings, I only get 2G and 3G. It does not let me enter the hidden menu either, it tells me that it does not work on this device, I can not solve with the combination * # 546368 # * 910 #, I select the option only LTE, the coverage goes away and it comes back in 3G. Please, if someone solved this problem can you help me?

Now My Verison Is LS99720a pls solve i need to downgrade or purchase to sprint?? My country hav no sprint carrier

Well, you are kinda boned. There is no LS997 KDZ so you can't downgrade, and you can't use the VS995 KDZ since you are ARB 1.
Lesson learned, don't ever take an OTA update -- period -- rooted or not unless you are not rooted, AND you are using a carrier branded phone ON the carrier it was intended for.

Any other setting for invalid sim?? When power on Show ooredoo sim i use and 3 second later show invalid sim any service prevent ?? And i wanna know my device is root or no root '' bootloader unlocked or locked?? Where i check ? Pls help bro

I have the same issue. Downloaded the update and now invalid sim. Can't use phone txt or internet etc. Nothing mobile. Is there any fix for this? Who's fault is this? If my phone is now destroyed, can I get somebody to replace it? LG? Android? Phone was sprint. Used with cricket for around a year until this need the other day. Neither carrier knows how to fix. Thanks

I also have an LS997 GSM Unlocked (I bought it like this, not sure how it was done) and it was still unlocked after update to Oreo LS99720a. I didn't update it while it had the sim inside, and I factory reset after Oreo update. Try toggling network mode in settings to LTE/GSM/WCDMA and between CDMA/LTE + EvDO, but keep it on LTE/GSM/WCDMA. If you didn't properly unlock it, this may be the reason. If you can also see the CDMA Subscription option, set it to RUIM/SIM from NV. You could try DFS CDMA Tool 14 to change this if you can access DIAG mode from the hidden menu. I'm thinking the Sprint-TMobile merger (will be T-Mobile) will result in horrible OTA unlocking methods like they do currently instead of SIMCK, NCK, NSCK, or SIMCK. They'll likely rebrand the LS997 to T-Mobile and introduce their OTA unlock.
For now, try this:
Go into the phone dialer and type: 5689#*997#
Go to Field test > Modem Settings >RAT Selection > SELECT: GSM/WCDMA/LTE Auto
If it doesn't work, select LTE/WCDMA, then toggle back to GSM/WCDMA/LTE Auto
If it still doesn't work, remove the sim and try these steps above without the SIM, then retry.
Don't forget to update your APN settings for your carrier.

Carrier Signal show bro ph know carrier too but (invalid sim) still show

Go to the Sprint store (a legit Sprint owned one) and either get a compatible sim or have them fight extra hard to activate the sim you currently have...and idk if your still with Sprint or not...
---------- Post added at 06:12 PM ---------- Previous post was at 06:10 PM ----------
Also if you have the receipt you can try and get the sim unlock code from Sprint but since your not in a contract idk if they will give it to you...

Sprint does not have unlock codes. All you have to do is chat with their international division and they'll uicc unlock it for you.
This is important. Ask them to lock it from their end then ask them to unlock it. If your Sprint phone is paid off and clear then they will unlock it for free to use it on TMO or at&t

I've tried they keep saying that the phone is still unlocked on there end

I can't find these items!
Thanks for your reply.
I have the same exact issue. I tried your method to reach the hidden menu. I only have:
- Device Test
- ELT Test
- Factory Reset
- Log Service
Is there something I am missing?

What variant do you have according to the bootloader?
Try removing your sim card... Boot the device... And see if the mobile radio can turn on with no card installed...

Did this happen after you updated to 9.0 Pie? Because My phone (Sprint model, flashed firmware to unlock) didn't recognize mi SIM after I took the update.
Where did you buy the phone? Are you absolutely it sure it was not a Sprint phone?
Anyways, I had to flash back to an old firmware, flash a couple of modem files, and now my SIM is recognized again.
I did what this gentleman did...

sprint lock shows "invalid sim" if i'm not wrong , mine is unlocked version and i did ask sprint "i will attach their reply"

had issues calling only certain people and as someone metioned i tured off the " enhanced 4G" and it works fine now, my carrier supports it but it seems buggy...maybe need a we need "official carrier" for it tot work right.
im personally on Tmobile and everything works fine now. I guess its called HD or advanced calling that i had to disable. i attached screenshots. hope it helps someone
