Hey all,
I apologize if there is a thread for this already. I have the Sprint GS3 that I made the terrible, terrible mistake of upgrading to the stock 4.3 to give it a try and see if I like it.
After some scary moments trying to go back to the beloved CyanogenMod and bricking the device, I found I could install Cyanogenmod using their self-installer after restoring the phone to stock in Kies.
I'm running Cyanogenmod now, but there is an update available and when I try to let it update, it reboots into recovery, gives the sad broken android graphic, and reboots. I've not been able to install anything ROM related since.
Is Knox preventing the update, and is there a workaround to get the update to install without wiping the device back to stock?

I will give you my two cents. First, rooting and installing custom ROM's should not be done using magical wonderful "one click" processes or apps that will do it for you. The Cyanogen Installer was a huge disservice to the rooted community in my opinion. Users need to get their hands dirty when rooting, so that they know how to work through problems forwards and backwards. That being said, I would highly recommend following this procedure to make sure your phone is rooted properly and running the correct recovery (Philz Touch, which is unbelievably awesome); my friend @goku2778 did a very nice job putting this tutorial together:
http://forum.xda-developers.com/showthread.php?t=2596697
After that, just download the ROM (or ROM's, I like to run various ones at any given time) from the proper sources, and flash them yourself.
I'm against one-click stuff myself. I've been rooting and running custom roms since my original Evo 4g.
If bricking my device after trying to roll back to a custom rom after Knox did it's business, and then recovering back isn't getting my hands dirty, then I don't know what is. I've spent plenty of time in adb. This issue though has me boggled. Why can the installer put a custom rom on when attempts to flash a custom rom (usually run nightlies) brick the device?
Thanks for the link, I'm taking a look into it now.

Didn't mean to imply that you weren't getting your hands dirty in general, just the way I word that rant every time I give it! My understanding is that there are compatibility issues between the CM installer and Knox, so yes, that is probably the basis of your problem. The combination of Philz Touch recovery and SuperSU that @goku2778 uses in his tutorial should solve your problems, it is the combination I have been recommending to VM and Boost users on Android Forums for a while now, with great success.

If memory serves there is a zip out there somewhere that flashes Knox apps away. Furthermore if it's a Boost or VM device you have to edit the updater script to make a Sprint ROM flash successfully.

The DeSamsungnizer zip is part of the tutorial by @goku2778, but keep in mind that this just takes care of the Knox apps, the actual bootloader is never ever going away unfortunately. And yes, for any users of VM or Boost who are reading this, there is extra work involved once the custom recovery has been installed and root has been successfully achieved.
Galaxy s3 on Virgin Mobile running cm11
I recently upgraded my s2 which was running cyanogenmod 11. I rooted and flashed everything myself with no difficulty. But after I switched that phone to an s3 I have had a ton of issues. My s3 was for Virgin Mobile (sgh-I747M) and nothing supported it. I was able to root and install clockworkmod with a little bit of difficulty. It wasn't until I tried installing cyanogenmod that it got really tough. Flashing would fail and at that point I didn't have an os so I thought I downloaded stock but was wrong when I hard bricked my phone. Anyways to the point. I ended up using the cyanogenmod installer which worked perfectly fine but now I can't update or download any nightlys. I'm not sure if it is because cyanogen had to install a custom kernel or not. When I go into system updates it says "your system is up to date. There is only one button that just checks for updates. Does anyone know how to fix this and allow me to install nightlys?

Will CM installer work on S3-i9300(Int) version with 4.3 already installed?
Hi,
I am using the International version of SGS3- GT i9300. I dont know any of the process of rooting or installing a new version of android. But recently i have come across the cyangonmod installer app which i heard does all the work for us. I want to ask this doubt is that will the installation cause any problem if my S3 is already updated to 4.3 version? I am hearing people saying the KNOX might cause error. Should i wait for the CM 11 stable version or just give it a try ?
Thanks.

did you figure out how to get nightly updates, from cyanogenmod installer ? I want to try the cyanogen installer to get cm 11 on my gs2 and gs3 (my specific devices are not on the cyanogenmod devices list, so i'm hesitant ) .. please respond .. anyone who can help ..
I have a specific problem .. I think in order for anyone to understand it, I have to explain it well.
I was flashing the new LegacyXperia ROM on my Xperia Arc S (http://forum.xda-developers.com/showthread.php?t=2545354) .. before, I had an older version of LegacyXperia already installed, with CM10.2.
Anyhow, I forgot to flash the boot.img! I did everything else as I should and istalled the ROM. Yet now when rebooting the phone from recovery, it only gets to the "LegacyXperia" screen (I don't know how this is officially called .. it's the first screen you see) and not further. Well, if I press the home button when it's starting, I get to recovery mode. .. So I've been trying my best to fix this. This includes:
Currently I have another Arc S device to work with - I have made a backup through recovery on that device (which works perfectly, running a different ROM) and tried to run it on the "broken" device .. recovery said it went well, but when starting the phone, nothing changed.
I've tried installing a different ROM (the one that is also installed on the second device), but again nothing changed.
I've tried wiping pretty much everything but the "dalvik cache" (since I don't know what this particular cache is) and installing the different rom and/or using the backup. Nothing made a difference.
I've even made an attempt on install the forgotten boot.img - I've taken the previously mentioned backup, put the boot.img into it (all that was on the SD card, via my computer, of course), and added the md5 values to the md5 file. Well, my phone was giving me a md5 mismatch, so I tried wiping everything off the md5 file, which seemed to do the trick (this is a useful thing to know!), since I was able to go through with the process of recovering the boot.img through recovery. After I've managed that, I've reinstalled the LegacyXperia ROM as I should have in the beginning. Yet again, nothing changed! the phone still won't start!
I am really desperate and out of ideas. ..the only idea I have left is try to install an older version of legacyxperia (the one I probably had before) .. but since installing a completely different ROM didn't work, I have only little hope..
I was not able to get into fastboot .. I do not know if it's enabled or not, since it was not me who installed the previous ROM on my phone. I know, shame on me ..
I hope I wrote down everything one could need in order to help me. And please do help me, I ran out of ideas and would REALLY hate to loose this phone!
I didn't understand the part of adding MD5 values to the MD5 file, but whatever
I don't really see why the rom wouldn't boot up, unless the kernel just isn't being flashed. (Maybe the previous owner relocked the bootloader?)
Can't you fastboot the kernel?
Also, Dalvik Cache can and actually should be wiped when installing a new rom.
SOLVED
Yeah, I got the feeling the kernel didn't flash, too! .. perhaps the bootloader was re-locked, but I really don't see why one would be doing that..
I was trying to get to the fastboot screen (with all the button-pressing and usb-plugging), but didn't manage that. However, I found a solution! (and god bless the guy who put this up!) I followed this thread [it seems xda-developers won't let me post an outside link .. anyhow, it's a thread on androidgadgematic.com, titled "How To Fix Bricked Sony Xperia Android Phone With Flashtool [ Unbrick ]" from june 17, 2012] and managed to install the stock ROM without much trouble. Now the phone is again running nicely I did, however, have to get a seperate driver package, since the one supplied with the flashtool wouldn't instal - I googled the drivers and used version 1.5 from xda-developers' forum.
GOSH I'm glad this is over
I am very new at this, so I apologize in advance. I have the Virgin Mobile Galaxy S3 SPH-L710 running 4.3.
I simply wanted to root it so i could get rid of the bloatware and install Sixaxis and play emulators, but I didn't really know where to start, so I started looking around and found this
http://forum.xda-developers.com/showthread.php?t=2546505
So I basically did everything on there. I used Odin to install PhilZ Touch 6 Recovery (CWM 6.0.4.7) Did factory reset, wiped cache/dalvik. then installed the Odexed MK5 stock rooted zip, wifi fix zip, SuperSU update zip, and then the knox app remover zip.
Everything flashed just fine and it started right up. It had the Super Su app, but when I tried to install apps that need root permission it would say I don't have root access. I couldn't delete bloat apps and Super Su didn't show any apps and there isn't much I can do with it. So I guess it didn't work? Either way I wanted to try a different rom. Was gonna give Cyanogenmod a try. But every time I try to install it I get the little "Android bot laying on his back" thing and it says status 7. I tried to flash CM10, CM10.1, CM10.2, CM11. Nothing worked, same thing every time. Even tried different SD cards just in case of a mess up.
The phone itself works fine for now, calls and text work, wifi works. And it says there is an update, but when i hit accept, it reboots to recovery mode, does the "android fallen over" then boots back up.
Now here is my stupid part, I didn't backup the original cause the guide didn't say to. (Not blaming them, i should have know better) So I am assuming I have a messed up version of 4.3 and Cyanogenmod doesn't know what to do with me. I'm not sure. Here is where I am stumped and I have no idea where to go from here.
I posted this by accident in the wrong forum here
http://forum.xda-developers.com/galaxy-s3/help/tried-rooting-s3-didnt-help-t2879278
But someone decided to help me anyways (thank you so much). They said all i need to do is update my recovery. so I went here
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
And now I am running PhilZ 6.48.4, but I am still getting status 7 when I try to install CM11. I have tried CM10, CM10.1, CM10.2 and CM10.2.1 as well. I have been at this for days and i am going crazy because nothing I do seems to work. Does anyone have any idea what is wrong with my phone? Thank you so much in advance.

only thing i can think of Is Odin the stock rom and start all over with trying to root......
I don't know how to explain it, but now everything is working perfectly....
I went back to the first site I posted about, Redownloaded everything, did the whole thing over, and root worked just fine. So I thought I would try my luck with CM11 and BOOM, working perfectly.
I have been tearing my hair out trying to get this to work for days and days and now, poof, it's all working. I dunno how, but I will take it. Thanks for the advice in both threads.

Get towelroot, is an apk that root your phone with one click, after that just download your favorite super user from the market and done.
I learned about viper4android and that is what made me start this crusade. I literally spend all of yesterday researching and learning how to root and troubleshooting viper4android and I still can't seem to get it to work.
I rooted my phone and flashed the latest version of TWRP, and installed superSU as well. I initially had a lot of trouble getting the busybox drivers to install but I finally managed to get the latest version installed. The app busybox on rails verifies that the current version of the busybox drivers are installed.
I tried different methods of installing viper4android and I don't have any luck with any. I get the app installed but once I launch the app it asks me which drives I to install, I try to install the super quality drivers but the drivers will not install. I've done a lot of googling of what the problems could be but the "fixes" people suggest dont work. The latest thing I tried was installing SELinux and changing the mode to permissive before trying to install the the drivers but the drivers will still not install.
Any ideas on what to try next? I've granted all these apps permanent permission through superSU. The other thing I've been wanting to do is to remove all the ATT bloatware, but even the app I got for that called "uninstall" will not uninstall all the bloatware which makes me wonder if something is incorrect. However in the bootloader it says my phone is "modified" and "unlocked".
Any help would be appriciated, and I should also mention I have lolipop 5.0.2.
Your problem is the stock kernel. It has write protection enabled.
You need a custom kernel where the write protection is disabled.
Try ElementalX for a start : http://forum.xda-developers.com/showthread.php?t=2705613
or any Sense based kernel.

Do I need to install skydragon before installing elementx? Or will installing elementX sense 5.0.2 version be ok?
Edit: I read on a blog that you need to install skydragon first, but I saw no mention of it in the official elemtnx thread so I ended up installing elementx and it worked by I kept getting hung on the HTC logo on boot, I did a reset and it fixed it with the eleX kernel running. viper works no but it looks like I've lost data. lol. Always something. Now it's time to figure this out.

Like I said in my edit it's something I read online. I am new to this stuff and at the time I thought you would need a new ROM in order to install a kernel. I was trying to research what I need to do so I dont go in screwing something up and there was a how to blog that specifically mentioned you need a new ROM inorder to install the element X kernel. But that turned out do be flawed information. Anyways I've since read a lot about ROMs, kernels and what not and now have a better understanding of what each piece of the puzzle does.
Anyways, the phone has been kind of unreliable. I had previously used the phone since it's launch before rooting it. I figured it might not be a bad idea to clean everything out hoping that would solve some of the problems. I relocked the phone and did an RUU. I then rooted the phone again and installed elementX. I cant send or receive multimedia texts, GPS does not work at all, and data works on and off. If I reboot the phone chrome will load any page but then after a few mins it stops and sometimes it will load certain websites and at other times it wont load anything at all. I am having good reception of course. Could elementX be the culprit here?

I searched info on AT&T with ElementalX .. what I've found they worked.
So not sure why it didn't work for you. You tried ElementalX-m8-4.05-Sense, right ?
Your first post was asking about Viper4Android, you need a custom kernel with write protection disabled for it to work.
You can RUU it back and try different kernel and see how it goes.
BTW ... what's the RUU version no. ? 4.28.502.2 ?

Yeah I was initially trying to get V4A to work, and flashing elemental X allowed me to resolve my problems with that, but now I'm having phone functionality problems. And yes, that is the RUU number that I used on my phone. Any kernels you recommend ? Also, as far as reliability and avoiding problems goes do I need to revert back to stock kernel everytime before flashing a new kernel or would clearing the caches and flashing a new kernel over another custom kernel suffice?
Can't help much on Kernel as I don't use custom Kernel.
You need to try some of them and find out which work best for your device.
Maybe asking in AT&T sub-forum will get you better respond.
The main point here is you need write protection disabled kernel to have that viper4android running and also to remove some bloatware that you want to get rid off.

Sorry for digging old thread but i have face the same situation like in the OP . My m8 has root access and ElementEX kernel installed but when i try to install viper4android it was asking to reinstall drivers again again . can you help me to figure this out ??????
I have finally found a method to get the Viper4Android working on HTC M8 (6.0)
1. Download viper4android apk from this Link - http://vipersaudio.com/blog/?page_id=48 (credit - zhuhang ) and install
2.Flash this zip in recovery Link - http://forum.xda-developers.com/showpost.php?p=64855827&postcount=5675 ( credit - Flar2)
3.Install drivers and reboot
4.Go to the system/etc and find the .conf file called "htc_audio_effects.conf" rename it to the "htc_audio_effects.bak" (this made file inactive but keep a backup in case something went wrong ) (Use Solid explorer or Root explorer for this )
4.Restart your device
5.Voila !! Now you have working Viper4Android
My Device Info
ROM - stock sense ( marshmallow)
Kernel - ElementX 7.0.0.11
Bootloader status - Unlocked (btw S-ON)
Greetings,
I really don't want this to be a repeat post, so I have spent many days now searching for this answer, not just here on XDA if I was honest, I have links to prove it
The aim is to give a little new life to my old phone, and get off the 4.1 build it is on.
With that said, in summary, I have tried a few different custom ROMs; Cyanogenmod 11 - 13, stable to nightly. PAC MAN ROM for Lollipop, some other roms for KitKat I found else where, but in all these I have not been able to get 4G to work. I understand about updating the Modem, and got the latest version from DocHoliday77's post for the Galaxy S3, in point of fact I tried every modem version for 4.3+ on there
But for all this, and it's been time consuming I never managed to actually get 4G to work as stated
I tried playing with settings in Test Mode (*#*#4636#*#*), changed preferred settings, added APN's, rebooting during certain phases of the moon ... but somehow it all avails me diddly.
Finally I have genuinely tried searching for info on if this just isn't going to happen and that's how it is, but somehow I found lots of posts about other models or networks that made it work more than something saying this won't work (putting aside the info on CM 11 that states it's a known issue and won't work on some build I forget).
Which leads me to this post: I wondered if anyone could point me in either the direction of a 4.4+ custom ROM or other ROM, compatible for SGH-T999 (T-Mobile Galaxy S3), that has working 4G. Or how I can get 4G to work on one of the ROMs I have already tried, kind of partial to a nice CM but I am willing to venture.
Also happy to just hear other input about giving new life to the phone so any feedback welcome
Thanks for your time!
NOTES
======
Using TWRP 3.x for flashing
Phone is rooted
IMEI is visible & fine on custom ROM
4G works on stock ROM
not experienced at this but willing to read
Edit: something I had not noticed before, I install Gapps for most of my tests but never use it. I just tried to download from Play Store, it acts as though I have no connection; waiting to download appears, then eventually it says waiting for network. Yet I am able to browse the net fine with the phone floating between 3G & H+. I don't know if that might help, so figured I should add it.
Is the phone running the latest bootloader and modem? Maybe both are needed to properly get 4g on all Roms?

That's a really good question, let me see if I can find out how to get my bootloader info and I'll get back to you.
May I ask what the latest bootlader is for the SGH-T999, or where I could find this so I can compare it? I couldn't seem to find it, though the most resourceful post I did find related was T999 UVDMD5 Firmware / Bootloader by mnasledov, though it is also a little outdated it appears, I haven't read my entire way through it yet sorry, I also know the phone is a little outdated too .
So that wasn't too bad to find out
I don't have the latest bootloader if that should match the baseband I install.
Where after a ROM install I get my baseband to T999UVUEOH1, but the bootloader stays on T999UVDLJA.
I haven't quite found where to get the latest bootloader just yet, though I did really spend the last few minutes discovering about the bootloader; if you or someone could find the time to point me in that direction that would be awesome
Simplest way to make sure you have the latest would be to flash the most recent stock rom from sammobile.com in Odin.
Thank you very much @audit13, I do appreciate the time you took out to help me and I also appreciate the point in the direction of what next.
I'll go dig into that for a while and see what to do to be sure, before I start
Looks like this is the latest one, so I will give this a shot : PDA T999UVUEOH1 & CSC T999TMBEOH1, version 4.3.
So just as a quick question, since I've never upgraded the bootloader in this fashion etc., from what I have read this is a one way street correct? And since I am upgrading to stock, then I guess will I lose root, which I will have to go back down the path of for a reinstall, or could I flash my old back up over this from TWRP and in that fashion have the latest bootloader, but keep everything I have for the moment as I investigate a ROM that will offer 4G.
I guess what I am getting at is even if having the latest bootloader and some other ROM with the latest baseband doesn't give me 4G still, can I go back in terms of the OS version to my 4.1.1 and keep things as is with a newer bootloader?
I will investigate this myself too, I just always preferred some additional input when discovering things where possible.
I do appreciate your time, thanks again!
No, you cannot run stock 4.1.1 on a 4.3 bootloader unless it is a custom 4.1.1 rom based on a stock touch wiz rom.
I do not think it is a problem to run the latest bootloader and modem as the latest custom ROMs often require an updated bootloader and modem.
Once on a 4.3 bootloader, you can't downgrade to something older.
Thanks again @audit13, that matches what I have read, I appreciate the confirmation!
Looks like I will be undergoing a re-root etc. so I'll get my information together, have a little more read, see what I need to back up and then jump down the rabbit hole
I'm grateful for your time and help.
If you decide to run a custom rom, just flash a stock rom, then immediately flash twrp via Odin, then install the rom and gapps. No need to root before hand.
Ahh ok, that would have made the most sense. However I didn't have an opportunity to check back on this thread until now so even though you had awesome speedy reply I missed it.
I did manager to successfully flash the stock ROM from Sam's. It did also update the bootloader so THANK YOU very much for that.
I had to fiddle a little to get Odin to recognize the my Galaxy S3 in the end it was simple: after I installed Kies to get the drivers on, I disabled WI-Fi (I use it for my dev work, and then it didn't try to spend time getting other drivers and it all went great. But that's just a note incase maybe one day someone else reads the thread and wonders how, this might help.
I'm just actually restoring a couple f things on the stock ROM, I figured I would have it ready in the event a custom ROM doesn't suit immediately, as I find one I like, then I have a back up of the stock ROM on 4.3 to revert to. Incidentally I just used TWRP manager from Google play store to install TWRP, hopefully it's the same as the flash, except now I know I rooted when I didn't have to
@audit13 Thanks, I know I keep saying that but I appreciate your time the same way I would hope someone else appreciated mine.
Incidentally once ready I will post an update here about the success of getting 4G on Cyanogenmod 12 or even 13 maybe, or someone of the other custom ROM I try, to share that info.
So just an update, I can confirm even with both an updated bootloader and matching updated baseband there is still no 4G on Lollipop Cyanogenmod 12, haven't quite tried any other yet, that was the one I liked the most but I will carry on and get a list as I have time then update here.
If there are any further suggestions I'm all open to them
Thanks [email protected]
Do you get 4G on a stock ROM? You have an LTE capabale sim? You get 4G on another phone with the same sim card?
Right, this SIM gets 4G on 2 other phones it's been in, on this phone on stock ROM it gets 4G too. Reverting back to stock backup in TWRP, from CM12 looks like it tripped knox I think it is, so now the warranty bit is 1 oops. But I managed to Odin back to 4.3 stock, so now I also need to see if I can try to flash maybe to CM 11, which is 4.4.x, or if maybe I'm stuck here. If I can find out I certainly will update the result of 4G testing.
You've been really patient & helpful thanks!
First let me say I'm a noob. I've rooted and jailbroken devices but I admit it's all from falling instructions. I rooted my s3 a while ago and installed twrp 1.0.8.7 yesterday. I did a full wipe including system and all catches and installed the latest nightly of cm13. Everything is running great. I don't know if this helps but maybe it's your process. Good luck!

That's really helpful thanks @Shack70, since updating to 4.3 I have only tried CM 12, I can certainly give 13 a shot, & you have 4G working then please?
incidentally I have actually recorded every step I performed, in the event I repeat this again or I had to explain it. But my process maybe at fault I agree; I rooted my phone with towelroot. Installed TWERP manager (3.0.2 something, maybe I should try 1.0.8?), rebooted into recovery & first thing was take a full backup on stock. Then I did a factory wipe, & advanced wipe. Then installed the ROM, wiped dalvik/cache. Installed Apps, wipe dalvik/cache, reboot
Hopefully that's not too much? I just wonder if any of those steps raise alarm?
Edit: mind if I throw a few questions on here at you please @Shack70?
what do you wipe from the options please?
after the install, do you run any other wipes please?
how did you get TWRP on your phone? Not sure if that or version matters but I'm willing to try

In twrp I wiped system and all caches before installing the rom and gapps. I installed an older version of twrp using Odin and updated it to 2.0.8.7 using the twrp app in the play store. Yes I have 4g/lte. I've seen it switch from lte to h+ to 3g depending on my location so I'm sure it's working correctly. The camera and Bluetooth also work fine. I hope this helps, I'm still learning and most of what I've done is just by following others instructions here at XDA.

I definitely appreciate the reply thanks!
I gave the latest nightly CM 13 a shot just now, 7/31/16 version essentially. Not finding any issues with the ROM, can't get 4G to show up no matter what though , even with changes and attempts to APN settings etc. None the less maybe to give my phone a rest I'll just stick with this a while and decide if a newer nightly comes out I want to try, or better yet a stable version at some point. Then I can verify how much I really miss my 4G I guess.
All the previous attempts, including this one always results in 3G to H+ network with no issue, it's just that 4G that never shows up for me.
Incidentally without a serious search around I couldn't even find TWRP 2.0.8.7, it's not on the TWRP manager version I have so curious, I ended up just going with 2.8.0.7, thinking maybe it was a typo?
Otherwise I basically run the same type of install you mention, I also clean dalvik, cache, system & data in my case. Just to confirm that.
I have a slightly off topic question here, if I decide to go back to to stock I was wondering, if i went from UVUEOH1 4.3 JB build, to the previous UVUENC2 4.3 JB build; because I've seen this available as a clean route 66 version, is this still considered a downgrade and a bad idea? I'd be flashing with Odin from @DocHoliday77 post here.
@Shack70, thanks for the input, thanks for the guide on your steps, glad I've confirmed I'm doing the same even if I can't get my 4G, hopefully someone on a Galaxy S3 T-Mobile, went through this found a solution, and maybe will let me know what they did too, not sure if you are on T-Mobile or not.
@audit13, also thanks, you've been replying plenty too and I appreciate that also!
One small thing I just came across looking over the logs of the install.
When flashing CM 13 with TWRP, I noticed it said the Target: samsung/d2tmo/d2tmo:4.3/JSS15J/T999UVUEMJC:user/release-keys.
Is it normal and OK for it the be referencing a different baseband/bootloader than what I actually have on my phone?
UVUEMJC vs the UVUEOH1? Where the one as named by TWRP flash is 2 versions older than what I have installed? Not necessarily stating this is an issue, just asking please if this is normal, and I also understand it could be something I have overlooked in my reading, it's been a lot of reading
I would not worry about the referenced baseband as flashing CM13 does not change the bootloader or baseband during the flash process.

That makes sense thanks @audit13, just a few of the questions I had building up.
So that my previous question doesn't get lost, and although I know it's a dying phone for users hopefully this might get some visual
