FreedomPop activation - reset necessary?

You all likely heard about FreedomPop's new beta this week featuring a "guaranteed 500 MBs of data, 500 text messages, and 200 anytime voice minutes for free each month."
http://www.freedompop.com/byod
Our phone is one of the supported models.
After you sign up, which involves giving them your phone's MEID and getting a new phone number, you're instructed to dial ##786# (which just ends in a dialing error for me), select the "reset" option, and use the MSL that they give you (which may be wrong, btw, so check it) to reset the phone and reboot.
Clarification: OK, so I discovered that the format is as follows for this phone, but I'm looking to avoid it: *#*#786#*#*
I don't want to reset my phone, however, and no one can explain why it's needed. Ting doesn't need it to activate:
https://help.ting.com/entries/25654386-Activating-a-BYOD-Phone-with-a-New-Number
Why does FreedomPop and is there any way around it? Surely there is.

Hmm. I just set up an account, gave them my MEID, updated profile and PRL and downloaded the app and didn't have to do any kind of reset whatsoever.

I think I've now seen those other instructions, where they say to do a carrier wipe (*#*#72786#*#*), system update, profile update, and PRL update, so I tried that but was met with an immediate roadblock: you can't do those things on CM. So now I have to temporarily go back to a stock ROM. Sigh.
First, can you at least confirm that data will work on 3G? Because that's all I have in my area.
Second, if I do go back to a stock ROM and make the above changes, will a Nandroid of my CM, later restored, wipe out those changes?

Well I am on TouchWiz (Project X) so probably. Idk about restoring a nand as this is my first day on it. 3G works great, seems like it uses Sprints towers (they mention Wimax on the website). So I would say flash back to TouchWiz, set everything up, make a backup and then try restoring your other backup. I would think after you're all set up you should be good because everything is done through their app. Kinda like Groove IP but with real service included.
PS- I didn't even do the carrier wipe

There, these are the instructions I got via email

I ended up going this route to update profile/PRL, and it worked:
http://e4gtcm.blogspot.com/2012/05/temporary-stock-e4gt-from-emmc.html
One unfortunate thing is that when you update profile, it forces a reboot, and when you reboot doing the above you go right back into CWM. So you have to install the ROM again just to get back in to GB so that you can also update the PRL. No doubt there's a better way of going about this, but I don't know what it is.
Anyway, once you've done that, you can intentionally go back to CWM and put CM back on. Nothing is lost in the process.

Could I get some help in figuring out why my epic 4g touch, which was on a Sprint account until 3 days ago.. and working fine... was not able to activate thru freedompop's website.
It said that the device was not supported. Anyone have an idea why this would occur?

Due to MSL-related issues or something else, they rolled back the devices that they're accepting. It is just a beta. As of 4 days ago, this was the list:
http://slickdeals.net/f/6449794-fre...voice-text-data-plans?p=63469084#edit63469084
Believe it or not, Facebook seems to be their primary support outlet, so perusing messages there should give you more current information. If you send them a private message, they're also good about responding. Fortunately, I signed up on the first day (which is not activating, btw), and that must be enough to bless you for later activation, since I only did that this weekend (after our device had been temporarily dropped from the list).

Oh, OK, so the order apparently doesn't matter. I might have tried that but I didn't know that the original order would ask for a reboot, so it was too late.

Install backup of Sprint Update app?
I'm hoping to resurrect this thread, but if it doesn't work, I'll start a new one.
I have a Samsung Galaxy S2 SPH-D710 that I'm using on FreedomPop. I've been able to successfully activate it on FreedomPop and get calls, texts, and data on a stock rom. I'd like to use Cyanogenmod 11, but I haven't been able to get the FreedomPop activation to work. I've tried flashing a stock rom, doing a prl and profile update, then flashing CM again, but can't get it to work.
While tinkering with the phone I had an idea: If I backup the Sprint Update app that updates the profile and prl on a stock rom with Titanium Backup or Root Uninstaller or something similar, can I then install the .apk that's generated on a CM install? I've tried this, but haven't been able to get it to work yet. Anyone with more knowledge have any ideas on this? I could post the apk I generated, if that would help.

Lollipop Reviews

I, like everyone, am looking forward to installing this update. However, I have heard from others (people with other phones or carriers) that Android L isn't all that great, mainly because of some bugs. Of course this may have had to do with a carrier's modification of Lollipop, so while this would likely be fixed, it certainly gives me pause to go to the effort and update (restore stock recovery, unroot, and other necessary prep work) to find out it's really not that fantastic or T-Mobile needs to fix some things.
So, I was hoping that those if you who have successfully updated could tell me (and others who might want to know) how Lollipop is for you.
Also, if you could tell us what you were before updating (rooted, S-off, using Xposed, none of the above, etc.) it would give us an idea of the difference in systems.
Thanks!

I was rooted, boot loader unlocked, TWRP installed. So I restored a non-root version and restored the recovery.img (took me a bit as I had downloaded an older version not realizing that so the OTA failed).
Upon the first boot up after the OTA, my wifi failed to work at all no matter what I did. I ended up doing a factory wipe (which wiped all my programs and settings - ouch) and now all seems to be working (but I am still setting things up).

I was stock unrooted, with S-Off and SuperCID. It took the OTA without a hitch. Had a little trouble getting play services to update, but after a restart it did fine. So far everything seems to be working. No bugs that I've found yet. Liking the new features a lot. Really wish they had brought VoLTE with this update.

I'm a long-time user of Team Venom's ViperROM, and only come back to stock for things like this.
I used an RUU to go back to stock, as the stock recovery I had wouldn't work with the OTA from my backup, and AndroidFileHost is down, so I couldn't use the only link I could find to get the latest recovery before this update.
Anyway, I downloaded the update just fine, and it installed just fine, and everything works just fine so far. It feels a whole lot snappier than before. I like the new notification system. The only thing that's driving me crazy is that I can't make the recent apps button into the menu button without installing anything extra. Come on, HTC, add that!
In conclusion, everything is as snappy and pretty as ever before, Wi-Fi speeds are good, call quality is good, and I am thoroughly enjoying it. When Team Venom pushes out their custom ROM, I'll be ecstatic.

I installed the new update this morning and rerooted after. I can't get AdAway to work properly. Otherwise, everything has been much faster and more responsive than it was previously. Feels like a fresh install. Only big issue I've come across is it uses GPS constantly which heats up the phone and kills the battery. I had to turn off GPS to avoid this. I think it may be related to the new Trusted places feature, as the updated Google service uses the GPS a lot.

I RUU'd back to stock after realizing that just going back to an old backup would still result in "Software Status: Modified." After I did that, update installed smooth. I haven't had any of the problems with wifi or data that some people have complained about. I still am not a huge fan of all the t-mobile bloatware, and will probably root/rom it within the month to something a little(lot) cleaner.

It was already rooted and the bootloader was unlocked before the update. I just had to reflash TWRP recovery, reflash the supersu.zip file, and then reinstalled supersu from the Play store.

Voice Dial
Discovered today that when you use a bluetooth to activate voice dialing now it gives you the choice to use the google/now app instead of the pre packaged voice dialer.

I was full stock and locked and accepted the OTA without issue of course. Had a little trouble with Google Play Services wanting to update but failing to finish the update. Did some reading and found a solution on androidforums that worked - cleared data and cache on both Google Play Servies and Google Play and then the update succeeded. Since then all works well and I too feel it is much snappier than KitKat. Haven't tried all apps yet but so far so good.:good:
Edit: I had used lollipop on my M7 reconfigured as GPE and really liked the Nexus experience. Since Jumping to the M8, I have chosen not to unlock and root (yet) as I anticipate a jump to the M9. That being said, I like the added features I have seen so far in the pure Sense experience. Notification on the lock screen are better, the Smart Lock works great at home and at work, so far no issues. Loving it. Will write back after a few days of exercise.

Hey, sorry for the basic question here. Just bought an used HTC M8. When I booted, i got the message "this build is for development purposes only do not distribute outside of htc without written permission. Failure to comply may lead to legal action," which I gathered means the phone is unlocked. What steps can I get to get updated to Lollipop?
Can I just download TWRP and flash RUU 4.20.531.4 from http://forum.xda-developers.com/showthread.php?t=2714456 ?
Or do I need to find a way to get to stock t-mobile rom and then back up and recover to 3.32.531.2 recovery before I can get OTA updates?
Thanks!!

You can do an RUU, but the first thing I would do is get S-Off. I don't know if it is still Sunshine (an app that was $25) that is the leading method, but even still, it's worth it. If you have S-Off, there are really no mistakes you can make and can't undo....[well, you can't brick it or throw it in a lake].

I am so dependent on customizations, such as button modifications, definitely Ad-Away, and other things, most of which were possible with a custom ROM, or Xposed, but since Dalvik is gone, I understand Xposed won't work. This gives me pause. No matter how nifty Lollipop is, if there is no way to do certain customizations/modifications, and if Ad-Away won't work, I would seriously consider waiting until these things are remedied.

It works fine, UNLESS you haven't disabled system RW protection but I thought everybody knew about that. If you are not s-off, or have not applied the mod to disable system RW protection, you will never be able to modify the hosts file while booted into Android system and so Ad Away app won't be able to either.
In this case all you can do is manually create a modified hosts file and push it with ADB or copy it through file manager while booted to recovery.

Messenger cannot send nor receive MMS
It's my only concern so far, HTC messages app works though, I've seen various reports about it but no fix so far. Everything else is running smoothly and I'm liking it. I wish wifi networks would be added to trusted locations but there are apps that allow this

I like T-Mobile Lollipop better than international, for one you don't get those annoying notification vibration.

Did they disable HTC Backup? Havent been able to get a backup to start when connected to wifi.

Ok, well I'm S-off, and the only thing I know about the system RW protection is that it exists and while I have one xposed module note that purports to enable it, it does not work. I know this because I can't get Root Logger to work. But right now ad-away on kit Kat is fine.
So is there an disable RW system protection mod I need to run? If so, when should I run it? Now before I upgrade (as I have been still hesitating, but it's getting difficult to resist at this point..especially with La Pollo replacement for Xposed (even though there are no modules written for it yet...at least we have the framework. )
Strange I didn't know about this system RW mod.... I will look around in the regular M8 forum, but if anyone can fill me in, I'd appreciate it.

Video and/or step by step firmware upgrade instructions available?

So let me explain the scenario; I have a T-Mobile M9 that's S-Off, running Venom, and wanted to update the firmware from 1.32 to 2.7. I had done this in late July and got the success, and the firmware was running fine, but eventually the phone decided to just shut off on me, and the only way to turn it back on was via forced reboot. For the two weeks after that I had tried just about every method I read on Sneakyghost's post on the subject (I did an RUU, changed to superCID and flashed 2.10, did the full wipe and no wipe firmware) and every single time if I updated to anything newer than what was on my M9 originally it would, inevitably, do that thing where it became unresponsive after a while.
Since this seems to be a problem that only I'm having, I assume it's something I have to be doing wrong. With that in mind, is there any sort of video that has been made or really, really simple and thorough step by step instructions that could guide me through the process in a detailed way? I hate that I have to ask this, but I feel like I've done my homework and tried several different methods, and all of them have failed. I have HTC sync installed, I've tried on two different computers, I've done everything. I even flashed back 1.32 in the exact same way that I flashed 2.7, and as soon as I put it back to the old one it immediately solves the problem. Without fail putting the new firmware on has made my phone do this at least once within two days of installing, and then multiple times after that (I must've tried this about four or five separate times over three weeks). The obvious problem here is that the phone is completely unresponsive, which means that if it does this overnight my alarm doesn't work. Not to mention the missed calls and annoyances that occur when it happens throughout the day.
I just want to be able to experience the new firmware. Because right now I still have to deal with a (relatively) crappy camera experience and a phone that overheats constantly. I'm also really worried that when the M update comes out it may force me to have a newer firmware, and if I can't do it correctly I'll be out of luck.
So if anyone could help it'd be so very appreciated, either by telling me something I could have done wrong (I flashed the firmware via fastboot method both over viper and later over a stock Sense build). I also have the newest radio, so I literally have no idea what I could be doing wrong at this point, but I hope someone does. Again, thanks in advance.

Nope, it's doing the same thing again. This is my GSam from last night.
Now, let me stress that I did everything clean. RUU, did a clean setup, clean venom flash, etc. I didn't restore any settings. I don't know what to do, as the phone is completely normal under 1.32. Oh and I flash 1.32 in the same exact way I do 2.7 as well, there's no difference

mobile installer application popup restarting phone?

About once a week, not really sure on the frequency, (if I notice the popup) it says it rebooting the phone with two toggles on the bottom of the box. (box and lettering all in black and white) Your choice on the toggles is reboot or later. Today I push later and it it popped up twice more. But on the third time, there was not toggles and was doing a count down for reboot.
Anyway, before it rebooted, I pulled down the notifications and and found the notification and did a long press on it and then went into info. I then it looked like I was in settings with two choices there. (when on this settings, there was not back button to see were I was at in settings) To block notifications with on or off and the other doing something with quite mode. I turn off notifications and minimized the box. After it rebooted, the box was still minimized until wanted to bring it back up in the screen, it disappears. Anyone know what this is??? or know how to figure out what's doing it?
Stock Sprint Note 4 running 5.1.1 software Ok1 with hotspot hack (why I'm not running current software)

Open root browser and see if you have this folder: /carrier/ItsOn
If so, you may also have this file in dalvik (i think that's the proper location for Lollipop but you could search keyword itson) : /data/dalvik-cache/carrier @itson@[email protected]@classes.dex
If your ROM is fully stock, you may have another folder at /system/vendor/ItsOn. If so, look inside that folder for resource zip. Extract that zip and look in the folder and file install locations then browse to those in your phone's folders and delete all that correspond to that mapping.
If you have those, delete all you find and reboot. Hopefully that cures the random reboots.
If this applies, ItsOn has a bootstrapper that tries to install itself. If you have a custom kernel, it cannot complete this process but will try repeatedly to complete that failed setup process, prompting you continually reboot. If you were to factory reset, the prompts would most likely be more persistent.
If you flash a stock tar, then flash custom ROM and don't wipe internal memory, ItsOn remains unless developer has a script in place to remove that from root of your carrier folder.

Thanks for the info. Phone is not rooted, bone stock with the exception of the hotspot hack.
Only thing I found using File Viewer under Root (/) folder /system/vender/Itson. And it shows nothing is in there and one year old.
I believe all this started when I upgrade Lollipop about one year ago. Was rooted at the time and wanted the newer android. Then I found out I did not need to root to get the hotspot working.

OK. Check ItsOn status next. Goto /data/local/tmp and look for ItsOn log. It shouldn't get added on boot if you've removed it but last successful bootstrapper log will be present, unless deleted.
FWIW, I don't have random reboots on rooted phone. When I had them, ItsOn was the culprit. I usually clean install, wiping internal memory before and after stock tar but didn't coming from Lollipop.
What I noticed was that ItsOn showed in hidden menu ##data# as NetworkSystemProvider. See before and after wiping internal memory screenshots. I suspect this carried over from Lollipop. Perhaps yours did too?

I could not find /data/local/tmp and look for ItsOn log, but I did get into data and the NetworkSystemProvider is there. Got into in and hit button for more settings and little window say "intent sent."
Also under more settings it says two things,
Module 1 is insmoded
Module 2 is insmoded
And at the top, it has a green icon for on button and a blacken icon for the off button. It will not let me do crap there.
Since it's stock, I have done nothing to it. Can't remember how I did the update. My guess since it was rooted, I had to flash OK1 myself but I don't see my stock download from Samsung. I have major memory issues, way more than I should at my age and I have no idea on how I did things......LOL And not even sure what Itson is, only thing I found with quick search a sprint software to add software and updates easily. That would explain the random downloads and install I did not do.
So now what, I need to root my phone to make this go away? Oh, and thanks again for your help. Don't go out or your way to dig further. I'm wanting to upgrade to MM but don't know much about it (rootable or hotspot wise).

The way I got rid of it was to wipe data and internal memory, flash marshmallow stock tar and wipe both again and flash a ROM that has it removed. Dunno but maybe it works the same way with a TWRP backup if you prefer stock with hotspot only?
I can't confirm there's another method or if that's your problem. But my random reboots are gone. FWIW, my log was inactive but had an existing log that dated months back. I only had a few random reboots until I did a factory reset to see if that would help. Once I did that, the reboots were much more frequent. Some boots were resulting in immediate request to reboot again. I had to do something at that point.
I couldn't tell you if updating to marshmallow makes it better but you could still could go back to Lollipop if it didn't.
I dunno if you need to root to make it go away but I can tell you there is hotspot mods for marshmallow. You can go back to Lollipop if you don't like marshmallow.

Thanks again, guess I'll give marshmallow a try here real soon. Maybe even try a custom rom, never played with any of those. But I getting to where I'll have to do something soon. I feel it's picking up the pace. Then again, new Notes will be coming out soon. We'll see what Samsung brings us. Thanks again.

I've had this happen before and the only way I was able to get rid of it was to flash a completely stock tar and let the device provision itself thru initial setup. Others have had luck with the removal of ItsOn, but this has happened on ROMS where ItsOn wasn't even present.

Thanks, I do just that when I decide where to go from here.

G975F TPA (Panama) - can I Factory Reset and go back to Android 11?

Multi CSC Panama (TPA):
Since OTA "upgrade" (or update) to the official Android 12, all I have is trouble with the phone, issues that I didn't have before. I asked about it in this forum, either no one else experiences this or people refuse to answer.
Can I Factory Reset and go back to G975FXXSEFUL1? Anything specific I need to do, order of things, etc? (yes, I know I need to fully backup before).
Thank you.

Nope. It will still be on 12 however if you haven't done a factory reset since the upgrade, do so.
It may straighten it out. There's probably incompatible apps loaded. Don't use SmartSwitch to transfer apps on the reload.
You may be able to reflash it back to 11. A Samsung Experience center can also do it... if they want to.
In the future if you don't want OTA updates, disable it. That's one of the first things I disable.

Thanks @blackhawk .
So, if I download the 11 image from SamMobile for example, I cannot revert it back to 11 after a factory reset?
If not SmartSwitch, how do you suggest I bring apps back, one by one?
OTA update wasn't done automatically, I clearly could have reject it, I didn't imagine it would cause so many problems, the most serious of which is the phone re-boots out of the blue while I am on a call.

Not sure how to roll it back, sorry. I run stock and been lucky enough to have never had to reflash any of my devices. You're starting to understand why I almost never upgrade. My two N10+'s are still running on what was factory loaded, 9 and 10. No issues.
A reset may sort things out. 12 is causing a lot of cursing from what I'm reading.
If you load the apps from Playstore it should flag any that aren't compatible. For now use the factory loaded versions of the preloaded apps especially system apps. Update those carefully after the reload if at all.

So after a factory reset and another OTA update (right after reset) to G975FXXUEGVA2 - my phone still reboots out of the blue, always in the middle of calls.
My original problem returned quickly, which is while on a call I stop hearing the other party while they hear me loud and clear. I start hearing them again after a minute or so.
Then yesterday 2 days after full reset the crash/reboot problem started again.
I suppose something got screwed up in the phone "radio" or whatever it's called, a hardware issue.
No problems at all with Wifi calling such as WhatsApp audio calls, so it has to be with the cell part of the phone.
Again - it started after updating from 11 to 12.
Can someone weigh in if it's possible to force a downgrade back to official android 11?
Thanks.

Does it happen in safe mode?
If not it's likely an incompatible app.
Otherwise it may be a mobo failure. A rollback to 11 may bypass the damage.
If the bootloader was upgraded too a roll back is possible.

I never go to safe mode, don't even know how to
I only loaded a handfull of apps after the reset to try and eliminate the issue. How do I go to safe mode?
Can't tell you anything about the bootloader, how do I check that? The upgrade was done OTA, all official firmware, no rooting or 3rd party stuff.

Google for the safe mode sequence. I rarely use it.
[Guide] How to Read Firmware Information
Hello Members, Today I'm sharing a firmware guide with you in which you can read and know about your Firmware information. Basic Firmware Information Firmware information consists of 3 information. Build version, CSC version, and baseband version. Let's suppose that firmware search result...
r2.community.samsung.com
You can go the same or higher for the significant number in the bootloader but not lower.
In this case it's a 2.

OK, so these are the four recent versions that I had, old to knew:
Android 11 - G975FXXSEFUJ2
Android 11 - G975FXXSEFUL1
Android 12 - G975FXXUEGULB (problem started with this one)
Android 12 - G975FXXUEGVA4 New update right after the reset.
Am I understanding correctly that E is the bootloader version on all 4?

I believe so. Apparently they shifted to letters.
Someone else here on a S10 I think it was successfully rollback from 12 to 11.
A safer course might be to let a Samsung Best Buy Experience Center roll it back. They can also do advanced troubleshooting.
I avoid mucking with the firmware and so far haven't had any reason to.
Don't let it OTA updated again as they may update the bootloader and then you're boned...

Well, I am boned either way
Thanks!

You're welcome.
Yeah it sucks. Malware is far easier to deal with than upgrades.

Was able to downgrade it back to 11, no crash yet, however my call issues are still going on (other side can hear me, I cannot hear other side), so it has to be a mobo issue. I installed only a handfull of apps for now but can't see how any of these apps cause it. These are all apps that I've been using before, major banks, WhatsApp, Waze, the minimal things I need. I guess a new phone it is.

Try it in safe mode and do a network reset there, see if that works.

I tried safe mode but it doesn't help me because safe mode puts it in Airplane mode and you can't turn mobile data on or make calls.
Also, why would I need network reset if I just did a full factory reset?

Did you test phone before loading the apps or updating any?
If a 3rd party app screwed it up already again.
WhatsApp I would never install... it only takes one. I doubt it's a hardware failure.

I did not test it. Some of the apps that I installed are needed for work and all of them, including WhatsApp, I have had for years. I am pretty sure it's a hardware failure as well.

You need to be methodical and not make assumptions. 3rd party apps can cause a lot of issues. It's more likely a 3rd party app than a hardware failure but only one way to know which it is. Something changed...

But there were no changes to apps when it started, just an update to android 12. And any recent app that I installed in the days/weeks prior to the update is not on the phone now.

You need to factory reset and before you install any 3rd party apps see if it's functioning normally.
If you suspect an app is causing the problem uninstall it. This doesn't always work.
Rarely a poorly written app can change settings that aren't user accessible and fail to change them back. A factory reset is the only way to correct this.
