Tomorrow I am going to have my Sprint phone flashed to work on the Cricket network. I just need to understand something. Once this is done is it written to the hardware? If I remove and install the OS several times am I going to have to go and pay to have Cricket flashed on it again? $85 is steep. Right now I am using the DCD ROM, but I may try newer roms in the future. Is there a way I can do this myself? Also will this flash allow the GPS, MMS, and internet work?
Thanks
What phone are we talking about here?
the Sprint mogul. has the dcd 3.2.2 Rom
Just rooted and unlocked. Using it on Metro PCS. Had service (text talk and web)
All my info in the device was correct but the evo was using a different phone number and using sprint (?!).
I contacted Metro to get service fixed I soft-reset the phone....now I have a signal but cannot get calls, text or web. (wifi does work however).
Any ideas? Do I need a new Metro Flash?
stumped....
I have no experience with the phone being flashed to metro pcs, but I think you may need a new flash.
I am going to re-Metro Flash the evo.... Not sure if I will have to redo the web settings but will provide an update.
Metro pcs unable to flash
I hope I can learn from this....
Metro PCS was unable to re-flash the device. I have MetroDroid 2.0 Rom and am rooted. I am considering taking Evo back down to stock in order to get Metro flashed again.
(For the record): Metro FLash was successful until I apparently messed up during rooting process. Although I was able to root the Evo later, I killed the info (i guess).
Any ideas on next move?
In the meantime, I will read up on un-rooting info
thanks!!
I have a post or two regarding my errors with having my evo metro flashed...
Although it was metro flashed successfully, my rooting wasn't which caused hell for me and the evo. (2nd time was a charm...or so I thought). While stock rom and internet worked, my actual phone service didn't. Then, no service at all.
Today, I tried to have metro pcs re-metro flash the evo and they couldn't, saying that their computer wasn't picking up the evo. The metro said that they had a rep from their flash service company trying and it didn't read.
At the time they were trying to reflash, I had metrodroid 2.0 (rooted) on the evo.
After that visit, I have gone back to the sprint stock rom (10-2010) and stock prl.
1) Do I need to get the cdma workshop settings reversed to reflect sprint?
2) Does being rooted prevent or have anything to do with the metro flash? My number and "metro pcs" show up in the phone settings...but not working.
3) Should I de-root then have them re-flash again?
thanks
I don't have any personal experience with this issue, but I think unrooting and then re-flashing may solve it, as certain files, ect get bypassed/overwritten with rooting, not to include any additional mods you made.
I'm looking for all the help I can get.
I have a Sprint GS4 mini and I got this for my girl. all my phones I've always picked it up directly at sprint so it was always activated so I wasn't away that I would have problems activating her phone that I bought online.
Trying to be proactive so once I gave her the phone nothing would need to be done. I rooted it and installed a custom rom so I could have the bloatware and everything setup nicely for her.
I found out they can't activate it because of the custom rom and it didn't have the sprint PRL. I know the easy answer would be to flash stock, but the 1 stock file that's floating around online does not work, it crashes in ODIN.
I have the Dev of the ROM working with me but i'm hoping to help him and me by putting this out to everyone to see if anyone has any thoughts or a good stock firmware.
Also is it possible for anyone running SPHL-520 to upload a nandroid w/o Data so I can try to restore. I'm lost on what I can do now.
Thanks guys.
So as I've looked into it, it appears that nothing has changed here in the 2-3 years since I last explored this issue. I'm talking about the fact that you can't successfully update PRL and profile on CDMA carriers in LOS and AOSP ROMS. The usual behavior if you even have the option in the UX is that you get a force close. I'd love to understand why this hasn't been addressed.. It's a huge reason someone would stay on stock over AOSP/LOS. I saw someone suggesting a Nexus 5 dev had some success using a couple of APKs including OmaDmclient.apk, and a few threads here and on Reddit talking about how it must've been broken by an AOSP contributor, but in any event it still doesn't work. Isn't this something that the LOS team could fix if they wanted to?
The issue with CDMA is that most of the stuff isn't open source. This is why the aosp source code is targeted to GSM. So I sought this will get fixed any time soon.
Same problem... I think
My neighborhood has excellent Sprint 4G LTE coverage and it's much faster than T-Mobile. I happen to use Ting (which allows you to choose between T-Mobile GSM and Sprint CDMA, although to switch from one to the other costs $20). GSM isn't really an option for me.
Anyway, I used to have this problem with my LG Volt LS740. I could work around it by forcing a PRL and profile update on stock and then flashing to Cyanogenmod.
That phone finally bit the dust. I have now inherited my wife's Moto G 2015 (osprey) XT1548. Really nice phone.... but the issue is, the latest stock I can find is Android 6.0. I can activate the phone and get great 4G LTE on stock, but to flash to Lineage OS 14.1 (or AOSP) I have to wipe the device. I simply can't get it to pick up the 4G LTE service on the custom ROM's (tried both). This is a real problem.
As I understand it (admittedly from reading Wikipedia), the PRL contains an "acquisition table" that prescribes the frequencies/modes that the device will communicate on... so I think that's probably my issue. After doing the prescribed wipes in the ROM installation documentation, flashing the ROM, and booting the device, I think I've lost the PRL somewhere in that process.
Is there some way to retrieve the PRL while the device is on stock and put it back when flashing custom? If the PRL is indeed stored on the R-UIM, should I just remove the R-UIM during the first boot? Maybe I'm wrong and the problem isn't really the PRL.
Any thoughts? Please don't tell me to switch to GSM. The GSM coverage here is just plain bad from both carriers who offer it in my neck of the woods.
I have this same exact question. Ting, N910P note 4 that was originally Sprint, and days-old Lineage 16 / Andorid 9.0 . The latest stock rom is 6.0.1, and works fine. Lineage 16 works 99% fine and I'd really rather use that. But LTE doesn't work. If I force it to use 3G only, it actually all works. data, voice, text, bluetooth, gps… and being Lineage, I don't have to try to surgically remove all the spyware and other crapware without breaking it. It's just not in there in the first place. I'd really rather use that.
I would be fine having to extract things from the stock rom and edit files or whatever if it were at least just known what needed to be done. I'm fine with the fact that Lineage nor anyone else can actually include and redistribute any carrier proprietary stuff.
it should be possible
Has anyone figured this out?
I too have devices on ting, fantastically built devices that run amazingly thanks to a solid construction, the support of many many developers who are craft some of the best ROMs for any device I've ever seen, considering the limited specs of the XT1031s. Fortunately/adequately enough though, they only run on 3G Sprint, Boost originally, moved to Ting for their great rates for FreedomPop customers when they bought them out.
Anyway, currently to get a device on ting, I have to flash the latest 5.1 official stock Boost Mobile Rom with the latest radio baseband and firmware and such. A process thats pretty involved. I'm hoping that I can backup the stock image using TWRP, as when I went through the process of reloading the official image through the individual files via mfastboot, I skipped the logo and recovery files, and since I was able to retain my custom logos for boot and bootloaderunlocked screens, and the recovery, I'm hoping to be able to make an image of the stock ROM, which if at all possible, I'm going to do my best to make as bare bones as possible. May start with flashing the bloatware removed version of stock thats available, then going through and removing basically every app on the phone with the exception of settings and anything to do with phone, phone/carrier services, sim toolkit, etc, so I can have the smallest image possible that could maybe be restored everytime/anytime that I want to update the PRL or Profile. Which it looks like theres a new version of each released at a minimum every 3 months, as I just activated another device this way and there was only an incremental update of the last digit. If this works, great. If it doesn't then I hope that theres an answer to the question in the initial post of this thread;
Is there a way to update the CDMA PRL and Profile on a device that is running a custom ROM? If so, is it something the ROM needs to specifically support or is it something that is possible to do with a bundle of apks? Like sim toolkit and the like?
If its ROM related, are there, or would it be possible to take the necessary components from the stock files and install them in Xposed or Magisk? Or perhaps the buttons in the settings panel of the stock rom simply executes a series of commands that can be executed within a terminal CLI on the custom ROM? I assume that since the custom ROM clearly has access to the 3G radio since I can make and recieve calls, I have data, and text messaging (haven't tried MMS, but I assume it works) so why couldn't it do one more thing and initiate the PRL update?
I assume that even the stock rom doesn't ever touch the PRL or Profile, seeing as they remain even after a user data wipe, and are available for the radio to continue to use with custom roms, which means that the radio chip has to be the one storing the PRL Profile, so I bet that the radio also directly downloads those files from the carrier when asked to do so, and the stock rom must only come into play for the base logicstics of it all such as radio-"is this prl/profile a newer version than the one that i have now?" and phone-"yes, download new, purge old, flash new, tell me when done and leave me alone" Since the radio doesn't have its own processor for those sorts of things perhaps? If thats the case, then that should imply that theres nothing particularly proprietary or licensed, etc, that a rom would explicitly need to have in order to initiate these updates since it would never directly need to touch/see the files, just know that they were updated and what version number they are. What also lends me to believe this is the case is the fact that you can't select to downgrade the prl/profile, rollback, or load one manually, at least not that I can see.
So basically I'm saying that I hope it should be something simple to do. And if it is simple to do, you would think that custom roms would be able to read the carrier correctly too? Right now my new device reads "Boost" still. My previous one when I got it on ting I wanna say actually read ting afterwards. But when I loaded ressurrection remix, I had no cell/data/voice nothing, It just kept asking me for a sim card, which this phone doesnt have at all. When I loaded Lineage, everything cell related work. But can't update prl/profile, and carrier reads as "3G Roming Indicator Off" Which idk why thats the case.
Perhaps I'm missing something
Perhaps custom roms are missing a few somethings.
The only sure thing is that carriers need to just not be so greedy/dumb/uselessly difficult, and make giving them money for service easier, preferably without questions. Or at the very least actually provide some security so all this nonsense is at least worth something in the end to the end user, instead of being done so that they can try to spy on your unencrytped texts and calls to sell to advertisers, and selling access to the higest bidders such as the government and bounty hunters, whilst preventing you from restricting that information.
