When I try to save the PPP settings for verizon (they are currently set to: [email protected] and I need to change to [email protected]), the settings continue to revert back to alltel!!! I really need some help with this - why would I be able to change every other setting via QPST except for PPP username and psw? Does anyone know if this has something to do with the registry? Thanks so much!
"I'm not really sure why you are editing these fields in QPST or why you would need to. If you have Verizon, flash with the latest WM6.1 that Verizon released, then flash with this ROM. Once you do *228 and get activated these settings will all be configured automatically."
I did that - I need these settings corrected so that I can access data. I am unable to do so because the settings keep reverting back to [email protected], even after I just changed them! I just now flashed back to the Sprint Stock ROM with radio 3.43 and still is unchanged!
I don't know what to do... I'm really freaking out - I did flash to an alltel ROM in the past, but why aren't the newer ROMS overwriting the old PPP settings???? Is it a radio problem (shouldn't be because I just flashed with Sprint radio ROM)
In any case, no matter what ROM I use, I cannot edit the PPP username and psw - it always reverts back to alltel. Does anyone know what I should do? Thanks!
P.S - I also installed the dcd Verizon Wireless carrier cabs and still no go...
I'm not really sure why you are flashing with all these different ROMS to be quite honest. I'm assuming that when you flash with these ROMS you aren't letting customs run? What ROM are you eventually going to be using? Do you care about being able to enable GPS?
All I care about right now is getting the PPP username and password changed.
It seems as though I cannot access the nvm folder using EFS File Explorer. I am trying to use QXDM, but I have no idea how to use it. Does anyone know what the commands are for changing PPP in QXDM?

Dude...flash with the official Verizon ROM linked below. Let customs run. Once complete dial *228 and choose option #1. Once that is complete you may have to call #8899 to get a new authentication key. Make sure your phone is unlocked with the 2.31 imcokeman unlocker, which I assume it is since you are already flashing away with various ROMs. Once you do this your settings will be fixed. You shouldn't be editing them the way you are trying. REFLASH WITH OFFICIAL VERIZON ROM...nuff said.

This is what I would do as well. What radio on you on. You say 3.43, but there is no 3.43. Check in Device Info in settings.
It souunds like you flashed an altel rom and let custmizations run.
Try flashing the stock rom (from verizon) and let customizations run. Then follow the steps to listed earlier in this thread (think the site was wiki pda) to get aGPS running. I wouldn't call Verizon for an A key until you are done flashing. Then the easy way to repopulate your phone is to go online to verizon my account and activate another phone on your line, then active your 6900. When you do this it automaticlly sends a new A key and don't have to try and explain to tech why you need it done.
Good luck
Okay I am doing that now. You are correct, I did let customizations run...
However, I was able to forcibly edit the NV Items using CDMA Workshop and that seemed to work...until I tried to edit the password with QPST. So I will give it a try and if it still doesn't work, I will just re-write the NV Items everytime I use QPST. Thanks guys.

The sreps I was refering to were in the rom thread, but here is a link.

I would be very careful changing stuff to verizon already.
I went into the alltel store and they won't even activate a verizon phone yet
because if you have verizon software they will bill you on a different account on verizon (if you're still under an alltel contract), which means that you will be being billed per minute and for data as a pay as you go plan.
she said this is because verizon and alltel billing systems aren't fully integrated yet.
so if you haven't resigned a verizon contract yet, meaning you're still on your original alltel contract, be careful.
I am using the Jiminy V Rom on Cricket
I am unable to OTA or make calls on the Cricket network. when I try and make a call I get 'Unauthorized' and when I try to OTA (*228) the system says 'unable' at the very beginning. I have done many EVO's to cricket before, and I have checked and double checked all my PST settings, my MEID/MIN/MDN/PRL particularly.
Even when OTA doesnt work , I can always get voice/text working on virtually any other phone by manually programming the MDN/MIN/Home SID & PRL.
My cricket home SID is 4923 & I am using PRL 32200
I have even loaded a working evo's PST settings into this phone (via QPST, read from one phone, write to another), and get same results even after making sure the MDN/MIN & MEID are correct.
The symptoms are exactly the same as if my MEID is not in the cricket system, yet I have triple checked them (and I had someone else program another phone with my MEID and that phone OTA'd and made calls on Cricket with no problem).
Some other data for consideration Android 2.1, build Baseband 2.15.00……007.25 kernel 2.6., Radio 2.05.00.06.10, HBOOT 0.79.0000 SHIP S-OFF
I have also tried factory builds 2.2 (3.26.651.6) and 2.1, (Baseband 2.05.00.06.10,Build 1.41.651.1) with same result. Note: they did not change the PST.
Is there a factory build which will put everything back to Sprint or should I consider updating the HBoot and /or Radio?, I assume the programming for the OTA is done in the Radio?
I am stumped.
Bump, If anybody can help me with this, its been driving me up the wall for two weeks now.,
Have you tried flashing an RUU and updating everything from there? If it isn't the MEID then it might just be your phone having a glitch. Flash it using RUU and let me know.
how do you reset PST/NAM (SPC,MIN,MDN, Etc) to factory?
I have tried RUU_Supersonic_1.32.651.1_Radio_1.39.00.04.26_release_171253.exe , hboot goes from 0.92 to 0.79, radio from 2.15 to 1.39.00.04.26, and android from 2.2 to 2.1.
But the pst/nam settings remain unchanged, mdn,min, sip, nai, etc are all cricket. even the SPC is still unlocked at 000000. ANd the S-OFF flag is off, Shouldnt the RUU's re-root the phone?
Is there an alternate way to run the RUU, I have tried putting the phone in HBOOT usb mode, then run the RUU but with three different batteries it tells me they are too low (under 30%).
Should I be in Hboot mode to run RUU? (I have been running it from the PC with the phone booted up.
To answer a couple of my own questions, none of the RUU's reset the EPST whether they where loaded from the PC via the .exe method or from the SD card PB31IMG method.
I found a reference to ##786# and found that yes that does reset the EPST (including the SPC) back to factory.
So I figured maybe the problem would be solved, so I updated PST for cricket (MDN,MIN,SID,PRL) and tried again, still no OTA and still 'Unauthoriized; when I try to make calls.
I am starting to believe I have a hardware problem, but how can most of the phone work and yet it have (apparently) problems transmitting MEID?
Seems like no interest here or everybody stumped. I am willing to pay some one to help me resolve this. contact to my email or post here, I will certainly let the forum know when I resolve this. Thanks

Your problem has different symptoms from mine (the threadstarter), it sounds like your prl is incorrect. If you have a correct prl & sid (these can vary for the market you are in , in Phoenix the SID is 4923 and I use the old nationwide non EVDO PRL of 1040) when you dial 611 you will get Cricket, regardless of your ESN/MEID being registered with Cricket, if this doesnt work do not go further. Find a PRL/SID that works (sometimes changing CDMA connect from Auto to Home only can help) . Also make sure MNC/MNC are set to 310/0. Country code/Carrier I think.
Once you get 611 to connect to Cricket, *228 (OTA) will connect to cricket, if It disconnects you before the music starts playing and says 'Sorry....' it is most likely your MEID is not registered correctly with Cricket. In Phoenix *228 always works on EVo's as long as SID/PRL/MEID are correct,
The message you are getting about a credit card required means you are connnecting to some other carriers network (usually Verizon) which is transferring you to someplace to allow you to make a call even though you are
"not authorized" on the network. Go back and check 611 & *228.*228 will load the correct prl for your area and rate plan, check after it runs to see what was loaded. It will also most likely overwrite EVDO settings including MIP, Sip, NAI, etc.
At this point your phone should work, talk & text.
I had the same problem and I look all over. I wanted to unroot and remove jimmy v rom. I was think that if i update to the new update that it will fix it self and i was right. First I had to remove the jimmy v rom, so i got ruu to update the htboot and that let me update to the new 2.3.3. It fix it self and f***ing A.

Can you be more specificwhat you loaded and what versions of hboot where involved? I downgraded to 2.1 (with RUU) and hboot .79 and it did not resolve problem.
So I have what may be an obvious question, but it's not one which I have run into before. (my previous device was a Droid 2 which used a fairly generic boot loader)
I got my phone used off Ebay about 3 weeks ago. When I did, I assumed it was a stock Dinc, and so collected everything that I would need to mod it. Low and behold when it arrived and I charged it up, it had already been rooted, S-offed, and had CWM on it (the auction had not mentioned it being a rooted phone) So it took a sum total of five minutes to flash a new rom in.
Now, on further digging around, I find it has an old radio on it, (2.15.00.07.28) and also still has the old owner's phone number in it. Now, a few forum posts I have read in the past few weeks have indicated that installing a newer radio rom may improve some of the functions such as the light metering of the camera... but I have also seen that doing so may bork the S-off as this is stored in the radio rom?
What effect would it have if I put a radio rom on this already rooted and now rommed phone (Albinoman's JBb3). Should I just do it, or should I return the phone to totally stock prior to upgrading the radio software? And also, is there a way to erase the old owner's phone number from the My Phone Number field since this is now a wifi-only device and i'd rather the OS not send that info out when it's not correct.
Or am I just completely off base and don't need to worry about the radio at all?
Thanks for any help in advance!
You dont have to return to stock to flash the radio.
With radios I think it depends on your area. One radio that works great for someone may be terrible for someone else. The general consensus is that updated/newer software would improve the experience but I think with radios it varies. If you do change the radio make a backup and check the md5. Latest dinc radio is in my SIG.
Sent from my ADR6300 using xda premium
Changing your radio will not mess up s-off or anything else as long as you check the md5 and take the proper precautions. Also changing the radio will not help the camera or anything else besides your cell signal.
S-off is stored deeper than the radio, but tools like unrevoked use certain versions of radios to gain access to this setting and modify it.
No need to revert to stock, and there is NEVER a need to go s-on unless your selling the phone or sending it to HTC. I see so many people say they went s-on to fix some kind of issue, or to upgrade and then the phone messes up durring the proccess and it makes it much harder to fix.
You can remove the number by accessing epst. Dial ##778# hit edit mode and type six zeros as the password. Go to each menu option editing the info you dont want there. Replace numbers with an equal ammountvof zeros (147-237-9900 = 000-000-0000) When done hit menu and commit changes.

Thanks for the answers, that filled in a lot of blanks for me I Figured I didn't need to go S-on, but I didn't know if, like on my old Droid 2, there were certain situations where I'd have to revert to stock before flashing.
UPDATE, I flashed the radio yesterday to 2.15 with no problems. Got a tiny bump in my battery (which tells me the old radio was working harder than it had to)
##778# didn't work for me though, instead it rang up "welcome to verizon" and wanted me to wait to talk to an operator about placing my call.
also tried without the third hash, also tried ##3424 and ##775... all with variations on the same result; either my phone is not in service, or my phone number is inactive... none of them accessed the menu system.
::edit::
I also tried variations on #program# and #data# with no luck,and tried turning off all the radios I could get at.
Any further ideas or steps I may be missing would be greatly appreciated. I also put in an ask over on the rom forum.

Have you tried *#*#data#*#* or *#*#program#*#*
Yeah, tried those as well... but got my answer, apparently only Sense-based Roms can use ESPT, and since I'm running Albinoman's JB rom, no go for me unless I flash over to a sense-rom, make the changes, then flash back. Might be a project for tomorrow while the laundry is going... or perhaps I'll wait for beta four of the JB Rom, flash to sense, do the tweak, then flash to the new beta.
but I'm getting there. in the last week I have inserted new kernels, new radios, And troubleshot this problem, plus dialed in my Nova interface tighter and tighter, in addition to the font toying and so on I've been doing. who knows, sooner or later I might even try to compile something.
thanks for the assist though. Is much appreciated.
well, at the end of the day, I never did get EPST working. I tried several different sense roms, tried installing the APK and pushing it from ADK, the closest I got was to punch in ##788# and it would say "loading requested resource" and then, nothing.
so now I'm on to Release Candidate #2 of Albinoman's 4.1 Rom and will come back to the phone number issue later.
Hey all,
The tutorial I used to install the ADB prompted me to run "adb devices" when the device is connected to make sure it's working, and that the serial number of the device should show up. ADB definitely works, as I have rebooted my device and put it into recovery mode from adb; however, the serial number showing up does not match that behind the battery (have attached pics).
I tried doing "adb devices" on an old mytouch 3g slide which I have rooted and flashed CM onto, and the serial number that came up matched the one behind the mytouch 3g slide's battery.
So, questions are:
1.) Does the T999L specifically not show the serial number, but instead some other number related to the phone, when one runs "adb devices?"
2.) is it possible the previous owner of my phone did some sort of modding before returning it, effectively changing the Serial number? (i have also attached a picture of the recovery screen, which seems to be running a clockwork mod based recovery...still new to this, but don't think that comes standard on it?)
3.) If my serial number has been changed by a previous owner, is there a way to change it back, but more importantly, should I even worry about it? things seem to be working fine enough.
While I have used xda forums a couple times, this is my first post a registered user. I have watched the (very entertaining) noob video and looked for my answer, but having not found it, am posting my question in what I believe is the correct forum.
Background on the phone/situation:
I'm doing the research to flash a custom ROM onto my T999L, which I bought unlocked and used after for only a couple days for $300 bucks from a local phone shop near my apt in NYC. Currenly in India, and phone works perfectly using an Indian Carrier's Sim (vodaphone). Running the Stock ROM, which restricts using the phone as a hotspot unless you have T-mobile's stupid plan, so I want to flash to get around that.
Seems like the first step to flashing is to Root the phone, do a full Backup with a Nandroid, and then do the flash...to do this I need Android Debugging Bridge (ADB), which I have succesfully installed...just was curiously about this descrepancy I noticed though.
If anybody has suggestions on a Rom to try for the T999L, let me know! I'm thinking trying to flash the Energy HD 2.0 ROM if that works for the T999L, but the website I found out about that from is dated (top hit when you google best roms for galaxy s3, a cnet post from October 2012)
Thanks in advance!
New developments
So after further dectective work last night, i realized even though my phone was still network locked to Tmobile when I got it used (the shop I bought it unlocked it for me), it had already been rooted (it has the Super User app), even though it's running stock rom.
I suspect that some sort of modding had been done by the previous user that changed the Serial Number stored internally as the evidence points to above. Is it important to change it back to match the one on the sticker before I try flashing a custom ROM?
So no one has any thoughts on this? Have any other T999L users experienced what I describe above? Could someone try it quick on theirs and see what happens?

Custom or "Special" Kernel to allow QPST/QXDM or DFS to WRITE LTE NV Values?
There has been some old threads asking this, but none with a solid answer.
To Summarize
1. I have a HTC 10h (EU Variant) 2PS620000
2. I want to ENABLE LTE Bands 2 and 4 to allow the T-Mobile AWS and LTE+ bands, which is disabled on the 10h/EU model.
3. Tried simply flashing different radios, but only LTE band I got was Band 12 (700MHz)
4. Acquired QPST/QXDM, and DFS (CDMA Tools)
5. I was able to get into DIAG Mode (with proper drivers, which was a PITA), and able to read all the NV tables.
6. I cannot seem to write to ANY NV table, especially for 06828 and 06829 to enable the extra bands. When clicking "Write", the changes revert as soon as I re-read. I used SPC Code: 000000/PW: All F's to get in.
7. I even borrowed a friend's US Variant Unlocked HTC 10 (with the bands I want), and tried an old trick the Samsung S4 guys used to use to enable AWE on AT&T phones by running QPST Software Download (from this link: https://forum.xda-developers.com/showthread.php?t=2291589), and simply BACKING UP the NV table from the US phone (which contain the proper NV values), and tried RESTORING it to my EU phone. Everything "appeared" to run flawlessly, but upon reboot--the values were still the same as before.
8. Tried most ROM's and Kernels, including Viper10 etc, and ElementalX and CleanSlate kernels (have NOT tried CM's YET).
Now I've hit a brick wall. Some members have directed me to the M8 and M9 threads, where guys have reported flashing a Verizon RUU/Firmware to allow the LTE NV values to stick, but this does not seem to work on the HTC 10. I've tried everything and have gone this far, but I just cant seem to write the NV values. I've tried QPST + QXDM, as well as DFS. I am not sure if it's the actual firmware/radio itself (though I've also tried them ALL), or just the actual Kernel.
So the million dollar question: What is preventing the NV values from sticking? All my "write" attempts all appear "Successful" according to the program, but something is preventing it from actually writing the NV. Is this a Kernel issue? And if so, is there a ROM/Kernel out there that would allow this? If someone out there has successfully attempted this (on the HTC 10, not the M8 and M9 from other threads), can you guys share and perhaps put it as a Sticky in the 10 forums? I think this would be VERY helpful to a LOT of us.
Thanks

shouldnt flashing the tmous ruu/firmware suffice?
Are you S-OFF? I too have an M10h. Mine had an Arabic CID/SPC before converting to US-Unlocked. My LTE slow compared to HSPA+
I don't think the kernel is your concern however, the Linux kernel runs on top of the radio. You may need to convert to CID BS_US001 MID 2PS62500.
Even after doing this, my LTE is still limited.

Some members have directed me to the M8 and M9 threads, where guys have reported flashing a Verizon RUU/Firmware to allow the LTE NV values to stick, but this does not seem to work on the HTC 10. I've tried everything and have gone this far, but I just cant seem to write the NV values. I've tried QPST + QXDM, as well as DFS. I am not sure if it's the actual firmware/radio itself (though I've also tried them ALL), or just the actual Kernel.
So the million dollar question: What is preventing the NV values from sticking? All my "write" attempts all appear "Successful" according to the program, but something is preventing it from actually writing the NV. Is this a Kernel issue? And if so, is there a ROM/Kernel out there that would allow this? If someone out there has successfully attempted this (on the HTC 10, not the M8 and M9 from other threads), can you guys share and perhaps put it as a Sticky in the 10 forums? I think this would be VERY helpful to a LOT of us.
Thanks

I have a simillar situation as you. I am trying to unlook 3G band (B8 900 MHz) for my US Unloked HTC 10. At the end were you able to get some progress on this?
