We can get data after inputting the proper APNs. Our difficulty is trying to get hspa working over anything other than 2100Mhz.

I've kinda been MIA because of real life. We might be close. I'd like to get nv item 1877 changes to stick on reboot. Doesn't work on stock ics. I want to try cm10 (non Samsung kernel).
[Verizon Samsung Galaxy S III] tonu42:
Apparently the latest JB changes some things, can that maybe help us to change the NV item to stick?

use the latest jellybean release from Verizon and set the phone to world mode and gsm in settings. That will get you voice and text. After that download apn manager to enter the apn setting for st.
[Verizon Samsung Galaxy S III] dclifton1991:
ok what is the APN for ST. and i got a question i had my phone flashed to new wave wireless here in my local town in arkansas. they run off att and verizon towers but i only get 1x service and it is super slow on data. and i cant download the jelly bean update through settings and the check for update thing.. im assuming this is due to the fact i had my phone flashed is there a way around this so i can download jelly bean on my SGS3

thanks for all the help

Start a new thread in q&a and I'll help you out there. I feel like I'm hijacking a good thread.

sounds like you need to odin the VRLK3 leak and go to unlockit to get the apn setting.... ill be watching for a new thread to help you since this one is reserved for opening up the other frequencies.

Hi everyone,

Sorry I've been out of touch for a while, had a few other things to do so I was really busy for a while, so this phone issue fell in the cracks, not that it's still not VERY important.

I will update the bounty post pretty soon to reflect the ~ $100 more that was added to it.

Also, I read through the entire thread for new things that were added since I last looked at it. A couple of points I'd like to suggest to our most involved members, mybook4 and marcustaz, about what I've read:

1. Has it been confirmed yet whether NV item 1877 sticks after reboot if done with the AT&T CM10 rom, I saw that suggestion, but I haven't seen anyone dismiss or confirm it yet.

2. If the NV item 1877 restoration is caused by a location deeper in the firmware, maybe by a file in the modem partition, could we try checking with that? I see that it was confirmed flashing the AT&T LG1 modem does not hard-brick, using the phone without a working display. I also noticed that member Atsugai with two i535's is offering to use one as a test phone, with the other one as their personal phone running EDGE data with an AT&T sim. Since flashing the AT&T modem does not hard-brick, althought it causes a bootloop, if that extra phone is not required for daily use as it was mentioned, could we maybe get Atsugai to flash the AT&T LG1 modem and provide instructions try to figure out where it hangs during boot, or maye if it hangs at all. Even if having the AT&T modem loaded may not do anything towards reaching the goal right now, other than cause loss of signal (if we get past the bootloop), it may allow the problematic NV item 1877 to stick after reboot. If that is the case, it may help us localize the cause of that NV item reverting after reboot.

Just a couple of thoughts that came to mind after reading everything in one continuous step. I see we have made many very big leaps of progress in his thread, the most important ones being NV item 1877, the other was confirming that at least one AT&T modem can be flashed and still recovered from without hard-bricking the phone.
[Verizon Samsung Galaxy S III] mybook4:
Update:

Worked with Marcustaz today.

With i535 in VZW CM10 (with VZW modem), changed item 1877 to 0x8703E804. Item was changed while the phone was on, but again, on reboot, the item was reset to the stock value of 0x87016800.

Flashed an AT&T modem (UCLG1) to the i535 (which had VZW CM10 installed). The device booted fine, but the modem was pretty much unresponsive (wasn't recognized in DFS or QPST). Couldn't change the network type in Phone Info (nothing would stick). At least in this configuration, the AT&T modem wouldn't work with the i535 (completely expected, but thought we would try it).

Flashed an AT&T CM10 rom (with AT&T UCLG1 modem) on the i535. Had to modify the assert in the updater-script from d2att to d2vzw to enable flashing the zip. Device booted fine, but the modem was pretty much unresponsive (wasn't recognized in DFS or QPST). Couldn't change the network type in Phone Info (nothing would stick). At least in this configuration, the AT&T modem wouldn't work with the i535 (completely expected, but thought we would try it).

I've searched through the VRLK3 modem (in a hex editor) for every combination of 0x87016800 I can think of (00680187, 01870068, 78108600, etc...). I was hoping that the modem would be responsible for setting it.

Based on the above, I'd guess that item 1877 reverting has nothing to do with the ROM/Kernel and is done at some lower level. I'd guess the modem partition or in a bootloader partition. Since we obviously can't mess with any bootloader partition under and including aboot, I would like to try the following next (do not try this at home unless you are willing to brick your device!).

Because the modem isn't changing item 1877 back to 0x87016800 directly during boot, maybe it is doing it indirectly by restoring an nv backup of 1877 (a guess). When people were trying to get the bottom of the IMEI loss issue, one thought was that there was a blank nv backup on the phone, and that it was inadvertently being restored (thus clearing the working nvdata). One of the safety measures for IMEI backup was to run nvbackup as root (which would cause the phone to reboot and backup the current nvdata) in order to prevent IMEI loss from occurring in the first place by overwriting the blank nv backup.

Not sure if this is possible, but it might be interesting to see if we could change item 1877 in the nv backup, change 1877 the way we are now, then reboot to see if the change sticks (i.e. it may restore the modified backup we created). The problem is, we never found out exactly how it was stored. Based on the Synergy IMEI backup script, we know what partitions nv data is stored in, we just don't know how it's stored (probably compressed or encrypted).

We also still need to dig deeper into E:V:A's previous post detailing many of the device specific numbers (IMEI, ESN, MEID, SPC, etc). We may just not be changing 1877 correctly (however, we are mimicking the same method used to manually restore IMEI).
[Verizon Samsung Galaxy S III] AlexDeGruven:
If it's just a change to item 1877, and we can do that after the phone is booted, would it make sense to just put together an init.d script that would maybe change that item when a non VZW SIM is detected?
[Verizon Samsung Galaxy S III] mybook4:
I wish we could. Unfortunately the radio stops functioning when we change 1877 (until we reboot)

Want to help.

Hi I would like to help in anyway that I can! I have a Sch-i535 that I am currently using but have a back up htc phone I can switch to. I am using cleanrom in Global mode to get text and calls on a tmobile sim card. I am willing to flash and try modems roms ect to help get hspa+ or any other type of data on this device for tmobile. Im fully willing to learn anything needed and help completely just so I can use data on my phone! Please let me know if anyone needs a tester im glad to help and solve the problem I don't want credit or anything just to get data! everyone on Xda has been great to me so I really would like to get involved.:highfive:
[Verizon Samsung Galaxy S III] mybook4:
Right now the main focus is trying to get changes we make to item nv item 1877 to stick on reboot. Won't stick on cm10 or TW roms. I've searched through the VRLK3 modem in a hex editor, but found no occurrence of 0x87016800 (the default 1877 data) or any combination there of.
[Verizon Samsung Galaxy S III] nlopez1907:
ok, I understand a little. I have a few questions has anyone tried a T-Mobile rom/radio? what is the string 0x87016800 what dose it relate to ?Is there anyway to trick or rewrite board support packages to make a phone think its another device? (Ex; Make a SCH-i535 into a SGH-T999?) I feel like these phones are much like computers and can be changed to anything so it has to be possible to get it.

Unfortunately, until T-Mo moves to 1900MHz, we won't be getting H/H+ with a T-Mobile SIM. They currently run on the AWS band, which the VZW S3 doesn't support at all.
[Verizon Samsung Galaxy S III] marcustaz:
Isn't that the purpose of this thread and project? We are trying to trying to get the Verizon phone to support it...
[Verizon Samsung Galaxy S III] AlexDeGruven:
No. Even though the title says 1700MHz, it's not a frequency that's available on this phone.
[Verizon Samsung Galaxy S III] ac21365:
AWS was a wet dream of mine, if you read the thread.

If we can get this phone doing PCS WCDMA, I'll be ecstatic. If not, it at least does 2100 WCDMA, as proven by myself and many others.

We'll see, in time.

[Verizon Samsung Galaxy S III] AlexDeGruven:
Outside of 1700MHz, the problem is not the frequencies, but getting access to the APNs that give the data connectivity.

We can wedge the APNs in there, but we still can't get them to the point of actually working on the phone.
[Verizon Samsung Galaxy S III] jjjtriplej:
I tried out my T-Mobile Sim yesterday and today and got fantastic 2g and voice coverage. The 2g was sufficient to complete VOIP calls. For $30 bucks a month I'm getting 5gb of data, unlimited text, and 100 minutes. I would love to say goodbye to verizon and keep my S3. I know the 1900mhz refarm is up and running in the Phoenix area where I live ( http://www.androidcentral.com/t-mobile-improving-coverage-lighting-1900mhz-10-metro-areas ). So my question is, at this point with the T-Mobile 1900mhz spectrum available in many markets, are we looking to solve an APN problem, or do we have a fundamental radio problem with our phones being blocked still? If I can help test at all, please let me know. I'm of little use on the development end, but I can flash anything that might be of use for testing.

Also, you can put me down for $25 for the bounty.

Thanks!
[Verizon Samsung Galaxy S III] mybook4:
It's not so much an APN issue, rather a radio / nv configuration issue.

We'll keep trying, but you may want to consider trading your Verizon S III for a T-Mobile S III. Keep in mind that Samsung/T-Mobile will be releasing a new S III that will support T-Mobile's LTE Advanced AWS network.
[Verizon Samsung Galaxy S III] CB620:
I have the 1900 refarm in my area. The 3G/4G still won't work for tmobile?

It's sort of confusing because the DNA works out the box with Tmobile and att 4g.

Once the nv items required have been cracked, then we need to work on getting the APNs right.

Wcdma - claro - brazil

I'm able to get hspa and/or 3G on this phone when I switch to WCDMA ONLY.

I use either networkmon or phone info (not able to download anymore through playstore but I have it if anyone needs)

Now. If I switch to GLOBAL mode. the phone will only work on edge however the signal (for voice/sms) is much better/stronger.

So the question is, what is the frequency that S3 are not able to get once you turn the GLOBAL MODE on ?

Thanks.

CDMA Tool?

I've only just recently gotten into cell phreaking, let alone using one of these wretched "hand computers". Currently equipped with a VZW SGS3 i535 w/root66 (Odin ROM) and unlocked VRLF2, I've managed to tweak the radio using CDMA Tool, giving me the ability to receive calls and send/receive SMS with a prepaid AT&T SIM. When attempting to call out, com.android.phone FCs after being stuck on the dialer screen for about 5 seconds. I do not have a data plan, nor the ability to test MMS. I pretty much have no idea what any of this means or which information is relevant to this cause, but if anyone would like more info (if these findings are worth anything), let me know. Hope I can help.
[Verizon Samsung Galaxy S III] ysr84:
From what i have been informed there are 2 partitions one is on the modem and the other is somewhere fixed which is not accessible... once the changes are done on the 1877 item it comapres it to the fixed partition values (modem nv items with fixed parition values) and restores it back to original settings....

I was told 1877 is not an editable item...however i was given hope it can be edited but its hard to do it....

This thread will become locked. Congress apparently claims unlocking is illegal.....
[Verizon Samsung Galaxy S III] aslomagic:
So, on Europe they keep making more laws to force carriers to sell unlocked phones, or force them to unlock them after 3 months of contract, while in this "free country" you cannot fully use something you paid for (esp if you pay full price... Some phones are not unlocked even then)?? And because the Congress thinks it's a good idea to restrict freedom, why should we also cut our free speech by locking threads that talk about it?

Besides, there are people from other countries here where this is not only legal, but encouraged.

Additionally - Carrier-agnostic GSM connectivity is already open on these devices. We're not changing that, just figuring out how to add the access to the high-speed data networks.

You're in the wrong thread dude. Plus they aren't going to replace your phone under warranty when you done smashed the screen.

That's like wrecking your car and trying to get it replaced under warranty by sabotaging the starter. Sorry man but that's just dumb.
[Verizon Samsung Galaxy S III] mybook4:
I think he was offering to try something potentially risky on his phone (since he is getting it replaced anyway). There's a little bit of history to that in this thread. At one point we were entertaining the idea of flashing an i747 modem to the i535. We were hesitant to try it because we have a boot chain that is partially secured with secureboot. Later in the thread, Marcustaz had an i535 with a damaged screen. We ended up being able to flash the i747 LG1 modem to the i535. Long story short, we didn't hard brick the i535 by flashing the modem.

i747m from Bell Canada - getting HSPA+ 1700mhz from Wind

Hey Guys, I am pretty new to the community and I do not know much about hacking and cracking stuff.... but I tried to read many posts and experimented with my S3 i747m by changing a few NV parameters and I can make it work with Wind (Canadian Carrier who uses 1700mhz freq.) I am not taking any credit for anything and giving full credit to who ever has worked or tried to work on it.

I am just trying to help a few people out who are working towards it.

here are my findings and what I did.

- I have not touched any NV flag items, just item 01877 and changed 04 to 06.

- Initially it does not work, but after I restart my phone. I go to network operators and manually select my carrier and it connects.(I am getting HSPA+ connection)

- If I restart my phone second time, it does not work anymore and I need to change item 01877 to 06 again.

Possible reasons why it is getting changed to 04 again may be because of check sum, as we are just changing just 1 value. If any checksum is attached with it than we need to update checksum as well. so upon restart checksum of NV parameters is not matched and it is reloading all defaults. Expert may think on this as well.

It is good enough for me rite now, it is just like tethered jail break for Iphone. I am taking care that my phone always remain ON.

I dont know if all are experts here, and can understand all instructions, but I found it very difficult to follow instructions given in this forum and other forums. If someone who want to enable it on their phone and do not know how to do it, I would like to help them out by making a simple DIV. believe me, it is very easy, easier than rooting, anyone will be able to do it on their own. just put message below and I would help them out.

Again, thanks for help everyone

I am interested in lending my G3 as a test. I have t-mobile now in my G3 and would love to receive the other signals. Anyone want to help?
[Verizon Samsung Galaxy S III] preusstang:
So what do you think the scope of the checksum may be? All NV items? A specific subset? Calculate checksums and CRCs - 8 bit /16 bit / 32 bit and any other possibilities for the scopes defined above. Look at a raw NV dump and parse for those values, possibly towards the ending bound of your scopes.

That's my guess-and-check approach.
