[Guide] How to get CM10.1 properly working on Verizon Wireless Samsung Galaxy S3

NOTE: This is for the Verizon Wireless Samsung Galaxy S3 SCH-I535
Since I'm a new member I wasn't allowed to post this into the developers forum and before I continue: YES, I have searched valiantly for a fix to my particular problem and I spent the entire day new years and most of the day today trying to get CM10.1 to run on my SCH-I535 but ran into problem after problem. Every time I installed any version of CM10 or higher I ran into multiple problems: mainly being that I wasn't able to attain signal, the keyboard wouldn't load or there would be multiple problems with initial setup including having to restart during install so many times I gave up. In the past two days I have Odined back to stock at least 15+ times trying to get CM to run and now that it finally is I believe this is worth sharing.
Before I continue I should mention that your phone should be properly working so if you're in stock and you can't make phone calls or your IMEI is messed up then none of what I'm about to mention is going to work. After you Odin to stock using Root66.tar (http://www.megashare.com/4384479) then type *2767*3855# to reset to factory defaults everything should be running correctly. If not you may have bricked your phone or you have bigger problems for which I cannot help you and I apologize. There's also a torrent file available of the above stock tar file that downloads much faster here: http://forum.xda-developers.com/showthread.php?t=1840030.
So I assume, before I start this, that if you're on these boards you know how to properly root, unlock and flash then recover your phone through CWM 6+. If you do not know how to do this, then you will need to before continuing on.
Use this link: http://forum.xda-developers.com/showthread.php?t=1762709
Now follow Section 1 and pay attention to detail because if you don't you can mess something up and end up having to backtrack which can take valuable time and be amazingly frustrating.
Once these things are done you will need to reboot your phone back out of Recovery mode so you can properly move the necessary zip files onto your internal SD card.
Download CM10 Stable, you can find this here: http://get.cm/?device=d2vzw&type=stable
And download Gapps 4.2.1 here: http://www.teamandroid.com/gapps/ (I used version gapps-jb-20121212-signed.zip)
Put these files on your internal SD card and use EZ Recovery to Flash and then Reboot Recovery, I need to mention as well that when I dragged both of these zip files onto my internal SD I had EZ Recovery open while doing so. I don't know if that had anything to do with it but I thought it was worth mentioning. Clear the cache and data/factory reset then install CM10 followed by Gapps that you installed on the SD earlier.
Once you boot up you should have the phone working but the keyboard will constantly flash a message that it can't run, don't worry about that right now. Now download a nightly version of CM10.1 located here:http://get.cm/?device=d2vzw&type=nightly
(I used cm-10.1-20121231-NIGHTLY-d2vzw.zip)
Now put this on your internal SD card as well and hold the power button for 2 seconds and press restart then select recovery. Now that you're back into the recovery menu CLEAR ONLY CACHE then install the new CM10.1 nightly you just put on your internal SD and then re-install Gapps 4.2.1 from before and reboot. This all worked for me and writing this message is the first thing I wanted to do afterward to make sure no one has to go through the frustration and heartache of constantly failing at installing the ROM they want. I hope this helps at least one person, if you have any questions I will try and answer them to the best of my knowledge but I'm fairly new to all of this.

Or you can just flash CM10.1 first and do this.......
Tap the 4 corners of the screen to bypass activation screen then go into settings> more> mobile networks> and change CDMA Subscription to RUIM/SIM and System Select to Automatic then reboot...

Dirty flashing CM10.1 over CM10 is a much longer way then just clicking a couple buttons Its simply the fact that CM10.1 doesnt have the correct cdma subscription on default boot for our phone.

I have everything working properly now but I wish I would've known this was the matter that would've fixed my problem without all these extra issues. Now my phone app is crashing in the 12-31-12 version of CM10.1. It just suddenly started happening and I can't seem to get around it.

What are the correct settings?

I have been doing this a while... and I was already on the 10.0 stable build. So I flashed the 10.1 nightly... Now Play Store closes immediately after opening. I have tried to uninstall and install from .apk without success. CWRM opens and closes immediately , also uninstalled and reinstalled from .apk without success (You can get to it from booting to it with the phone off ). My Gmail app and account nowhere to be found. My attempt to go back to 10.0 were unsuccessful.

[Q] Please help, Root and rom has failed my phone...

I Rooted my phone and added a fresh ROM, for some reason the Gapps didn't install, so I downloaded a separate one and added it via recovery screen (holding down up, menu and power button) as instructed. However, now my phone won't work and when starts only says "Unfortunately, Setup wizard has stopped" once I clear this message, another pops up and says "Unfortunately, Google services framework has stopped" i click ok but the message just keeps appearing! my phone will NOT work, please someone help me, I tried re-rooting the way i did before using Odin, however, that didnt work, I can't seem to locate in the recovery menu where the faulty Gapps is located!
Any help is please welcomed, Also the phone is samsung note 2

What rom did you flash? You may have flashed gapps for the wrong android version. You need to make sure that you download the Gapps in the OP of the rom you want so you know you're getting the right one
Sent from my CLEAN Note ll

Have you done a Nandroid backup? Do a recovery or download a stock RUU. Goodluck man
Sent from my HTC One X+

I did that with my tablet once, I just wiped and re-flashed and put GAPPs on correctly and it was fine.

Failed Flash
Download an app like root checker to make sure you are still rooted.
What kind of recovery are you using on your phone?
You should wipe the phone completely, system, cache and dalvic.
Try doing the factory reset, check for root and follow the instructions from the original thread.
As stated earlier, make sure you download the correct Gapps for the ROM you are installing.
Also, you need some type of file explorer, I use Root Explorer. You can use that to search for the Gapps.
If you downloaded it on the phone it may still be in your download folder if not look in \system\app folder.

Hi everyone, I managed to fix the Gapps problem, however, now I have a problem with EVERY rom i install, i have tried Slimbean and Crashrom but I can't seem to get the EFS to work, i backed up using efs pro and an efs backup tool but it wont restore, so I have no network coverage, so i end up having to keep going back to ****ty stock, I have ended up going back and forth 18 times!! people say about baseband, but i don't know how to change that...

Your baseband is the modem/radio the phone uses.

I just did mine yesterday...It's easy, you already did the hard part. Look in the development section for http://forum.xda-developers.com/showthread.php?p=42792139 and download the Odex or De-Odex ROM. Verify the MD5 to make sure you got a good download and move it to the root of your SD card. Power off and reboot into recovery then perform a nandroid backup. Next "wipe/factory reset" the phone and finally "install zip from SD card" the Stock Rooted I535VRBMF1.zip file. The last thing you might want to do is flash the modem/firmware VRBMF1 also from recovery.
Before you start to panic the flashing of the ROM went surprisingly fast but on 1st boot the Verizon deal with the flashing circles was going for what seemed like five minutes for me until the OS finally came up. Everything is working great. You don't loose any personal data just downloaded apps and app data. You could back that stuff up but I wanted to start fresh and clean so I reinstalled most of my apps from the market. There is even a pretty good video someone added towards the end of the thread if you are a visual person

[Q] chameleon os superuser or root problem

I run chameleon os custom rom on Samsung infuse 4g. Superuser by Clockworkmod got binded/imbedded into rom. Was working fine, then out of nowhere got disabled under superuser settings and will not change back. I select apps only and all other choices but as soon as I select it, it switches back to disable. Google play no longer shows it as an app that I have downloaded so I can't get updates. I have tried installing it again both by just downloading it and by disabling it under app management and downloading it, but both ways when I open it tries to downloading binaries and fails. Same thing happens with any other superuser I try to download. I cannot get it to work. Please help. I no longer want chameleon as my rom because of too many issues with it constantly rebooting and internet only working sometimes. i want to try another rom but can't with superuser not working.

You mean to say you cannot boot into CWM recovery and flash a different ROM? Interesting. I have an HTC, and the steps to rooting it are in a different order... that after unlocking the bootloader, you install CWM, and then optionally root the stock ROM with the SuperUser package (those who don't do the last step are usually flashing a ROM instead of mucking around for another second with the stock OS).
SU shouldn't be needed for custom recovery. But maybe Chameleon does something weird like not give you a custom recovery you can boot into? If that's the case, you could pop the device into download mode and go back to stock with Odin, effectively starting from scratch.

still need help, thank you.
I am starting to believe more than before that the actual problem is that somehow my phone got unrooted. How do I set my phone in download mode and use Odin? I usually wipe the cache, install the rom, install gapps, wipe cache partition, and wipe dalvik cache. I have never flashed a rom before. Or even better what is the best way to root my phone again now that I am using chameleon? I believe if I can do that it will fix my problems and I can install cyanfox (the latest rom I have downloaded). Do I use super one click? That is what I think I used before but now that I am not using stock rom I don't know what to use.

If you are unable to get into ClockWorkMod recovery (hold Vol-Up+Vol-Dn keys while pressing Pwr button) and have it do anything (so your wipe, install, gapps, dalvik - that process would be called flashing). Then I would Odin back to stock.
For this, you would need to get into download mode. IIRC (just sold my Infuse), it is (with the device fully turned off) hold both volume buttons in while inserting the micro usb cable (that is subsequently inserted into your PC). The ODIN program comes with the download packages (hopefully), so extract the whole package, and run that.
Odin should pick up the phone in the first column as "COMX" (e.g. "COM5"). You are good to flash. To the right, there are PHONE and PDA buttons, click on each, and select the corresponding file (that was also in the package) for each (so PHONE will have something like PHONE.tgz.md5). Once both files are loaded, make sure re-partition is UN-checked, and press Start (or Go, or whatever the action word is). This will take a few minutes, but the COMX column should highlight green with "SUCCESS" in the end.
That's all there is to it. The reason why I'm shying away from SuperOneClick is that it was designed for stock gingerbread/froyo, so it has the potential of breaking something. Hope this helps.
EDIT:
Alternatively, you could try pushing su to the device with adb (depends on how you lost root):
Code:
adb shell mount -o rw,remount -t ext4 /dev/block/platform/msm_sdcc.1/by-name/system /system
adb push su /system/xbin/
adb shell chmod 06755 /system/xbin/su
... with this file (extracted).

new problem
I am now running cyanfox which runs android 4.4 and Google.process.gapps has stopped keeps popping up. To get rid of it I have to do a factory reset but after a few days it always comes back. I have Googled the problem and tried numerous things to try to fix it but everything only works temporary. What should I do besides get another phone? I can't afford that right now.

I wouldn;t suggest another phoen is things are working well genrally. The problem could lie in the GApps package or the ROM itself. I use the PA Gapps package. If you are having rouble with that one, try from a different date. Just wipe dlavik in between to prevent any nastyness.
If it still persists, try another ROM, like Carbon.

tried installing the new gapps
So far, so good but I won't know for sure for a few days. I'll keep you up to date. Thank you

what version of android is carbon?
Do you have the link for carbon rom for Samsung infuse 4g? And what version of android is it? My phone runs better with those gapps but I am still getting the same problems. I will give it a try but if carbon doesn't work I am definitely going to have to just get another phone. So far I'm. 0-2 on custom roms for this phone. I thought cyanfox would of worked cause I got it off of xda, which really makes me think this phone has some sort of hardware problem but carbon has been around longer. So maybe it will work better.

Carbon is on XDA as well too, and it is based on CM 11 / Android 4.4 Kitkat:
http://forum.xda-developers.com/showthread.php?t=2137800
Hope this works for you... :fingers-crossed:

problems solved
It appears it was definitely a problem with the ROM. Phone has been operating 100% better. :victory: My cache needs to be cleared frequently and some minor problems with the Facebook back but when isn't there problems with Facebook lol. But as soon as I clean out the cache from my apps, everything is running like new again. I greatly appreciate your help. I can't thank you enough.

Was working great then more problems
Joel,
Carbon was running great for me but then all of a sudden android.process.acore has stopped kept popping up along with all sort of other things stopping then eventually GApps not working again. I have erased my contacts, Erased Media, unchecked all my Syncs, I have tried all sorts of other Gapps packages and even another ROM (cyanogen 11) and they work to begin with then the same problems keep coming back. Is it because I went from Gingerbread right to Kitkat? My phone hasn't worked for about a week now with me trying all different ways to fix it. Do I need to install Ice Cream Sandwich then Jellybean before going to Kitkat or do I just need to try even more GApps? I used to install new ROMs all the time but android has changed so much over the last couple years and when i had to get rid of my old phone and went back to my Infuse 4g the old ROM was just completely outdated and now I can't seem to get this right. The phone itself is still a great phone and I don't understand why I am having these issues. I factory reset, wipe cache, wipe dalvik, install new ROM, install GApps, wipe cache again, and wipe dalvik again. I usually don't wipe the cache or the dalvik until after the ROM and GApps install but just lately have been doing the extra wipe just in-case because nothing else is working. But that has failed too. You have been a great help so far and I can't seem to fix this on my own, so again I turn to you for help. Please help me figure this out.

It's possible. I mentioned this before somewhere, but this could be the after-effect of a small /datadata partition, which having a separate partition is standard in a KitKat ROM (at least for this phone). When it fills up, there's no telling what happens.
Both BeanStalk and CM11 have /datadata partition alternatives (the separate partition has been abandoned) built in. You may want to try one of those:

Unfortunately I couldn't find something similar for Carbon.

Thank you!!!!!!
I hate to count my chickens before they're hatched but I truly believe that was the problem. Even Facebook works now. But I thought I had it fixed before then just under a week and it completely messed up and I couldn't even get it to work for a day after that. But it works now. I can't thank you enough. If you ever come across one for Carbon ROM please let me know. This is a good ROM but I liked Carbon better. Again, thank you Joel. :good::good:

Help!!!!!!!!!!!!!!!!!!!!!!!
Sorry to bother you again Joel but I have a major problem again and I dont even know wht happenned. You have helped me through evrything so far and I couldn't be more thankful. There may be nothing you can do to help me, I don't know. I was using my phone as A Wifi Hotspot when out of know where as soon as i got on facebook on my tablet my phone rebooted on it's own into Clockworkmod recovery. when I reboot it, it goes right back into recovery, it wont read the internal sd card and it wont install any zip off any inserted sd card(it reads them but wont install anything, it always pops up with android guy on his back with a red X and a generic error). it lets me erase cache but won't erase delvik cache or format anything, the screen just flashes and it pops back a screen. I dont think the phone overheated because it wasnt hot to the touch at all. I was only using it as a wifi hotspot for about 30 minutes when it happenned. i had used it as a hotspot many times before with no problems and i dont know how it woud be a virus when i wasnt on any abnormal sites. Any help you can give me would be greatly appreciated. Thank you in advance.

If you can get into Download Mode, I would Odin back to stock. Are you AT&T or Rogers? There are a couple recent threads in this forum with download links, although people have been having difficulties with finding the AT&T variety.
Unfortunately, that's all I can recommend. Good luck.

we'll see how this works out
I just checked and it will go into download mode. So I guess I just need to find the AT&T thread of Oden and hopefully that works. I have never done it that way before but I read your previous response much earlier in this thread on how to do it and it sounds pretty simple so hopefully I can do it. If you can find a link to the at&t version before me it would definitely help but I will see what I can find.

I would recommend Option D for what you need, but AFAIK, the links on this page are dead.
If you go to the last page though, there is a link for Option C, which would work for your needs. Hope this helps.

F***ed up badly, now downloading factory rom, need help to continue

Hi guys, I just registered @ xda because it looks like it's the only serious and feedback active community available. In 10 minutes I found most of the info I was looking for, but I still want to make sure what Im planning to do is fine before I mess up again. Here's the issue:
I was fooling around with the tablet and had just rooted it so I could get rid of some bloatware, and decided to go further and install cyanogen, just for the looks. So I got this thing cm-10.1-20130411-EXPERIMENTAL-p3110-M3 from the official site, which was I put on a folder inside the tablets storage (not on the 16gb SDcard it had in it). I downloaded Rom Manager and skipped through the "search and download rom" and went for the option of looking for it inside the SD card. I had the Backup options and the wipe cache and data ON.
So I proceeded and it booted, started to do the backup and at some final point it had an error, something like "could not backup Data!". I had the options of rebooting, some other stuff and the option of installing a rom from the SD Card. I went for it and searched for the .zip inside the storage, and installed it. It did it withouth trouble, and when it finishd it prompted me to install an update, which I didn't (don't know why).
Then, I went for the reeboot option and when it started I get the normal samsung's black screen with the device's name on it, but then I get a fast glitching image that sweeps through the screen and the cyanogen startup logo which gets stuck for ever.

Now Im past it, I can get to download or recovery mode, so I moved onto getting the original firmware so I can clean-install again. I got it from sammobile, chose the one belonging to Chile (that's where I got the tablet), and it's 729mb of data. The tablet is a Samsung Galaxy Tab 2 7.0 P3110
If I flash it with Odin will everything be fine? All I have to do is that thing in downloadmode when I rooted it, but with that 729mb file? Should I put it in the external SD or is it more convenient to place it in the internal storage?
I appreciate your help in advance, I know this is as basic as it gets but messing up again would cost me dearly, since I have to do other stuff.

forum.xda-developers.com/showthread.php?t=1900055 read here, all the information you will need.
It's fine to flash through odin, you will back at stock provided you don't overlook small details and do exactly like the way it is shown. Don't worry, Don't panic. Just be careful to use the files meant for your device only. Second be extra careful when you are dealing with kernel file, pit file or reparation in odin in future.
Third, get root and custom recovery,twrp.
Fourth, after your device start running take backup from twrp recovery. That will save you from most of the trouble.
Most of the details and instructions are already here

It's fine to flash through odin, you will back at stock provided you don't overlook small details and do exactly like the way it is shown. Don't worry, Don't panic. Just be careful to use the files meant for your device only. Second be extra careful when you are dealing with kernel file, pit file or reparation in odin in future.
Third, get root and custom recovery,twrp.

hey thanks a lot, im feeling better ow. There's just one issue left: I cant download the original firmware (it's 699mb, and the download keeps stopping midway through it). What happens if I go into clockwork recovery mode and do a factory reset? would that bring me to the original OS? Im kinda scared of downloading an erroneous file again.
EDIT: im doing a factory reset and then flashing this rom called AOSP Project Android 5.1.1 Lollipop on Samsung Galaxy Tab 2 7.0 P3110 which is a 161mb file. Will that work?

Factory reset is just clearing data and cache, if you have made changes in kernel or system, factory reset won't reset them, in your case, system has been altered so you will have to format system, then flash the new rom. If you were on jelly bean stock, you are good to flash it.

You guys have helped me a lot. I've worked everything out and now i've got to reinstalling android on it, AOSP's 5.1.1 Lollipop. It's beautiful. There's just one problem: Since it came with no apps at all, I wanted to install everything on it again. Problem is, when I go to google play, it shows that i've already got my apps installed, so it wont let me download them, and it doesn't matter if I place the APK's inside the tablet as there's no manager to open them. Even if I download apk's through the tablet's own web browser, it says it can't open the file. Any ideas on this?
