build.prop reverting to original after reboot? - Samsung Galaxy S7 Questions and Answers

I've edited build.prop dozens of times without issue, but I've just updated/re-rooted and now, every time I reboot, the file reverts back to the original. What's going on here? I've seen a few posts on this but never for Samsung devices and no solution. Is it a new security feature?
I don't have TWRP (can't get it to install) and on stock ROM.

I didn't make one as I was making a very minor change I know won't brick. But I still double checked just in case and there is no copy, .bak or otherwise, than the file itself so I don't even know where it's coming from!
My changes will be there and saved as long as I don't reboot...?

[Q] Can't Update!

OK, so I finally got the system update for the D2G yesterday. I'm not new to this whole game, so I removed Clockworkmod, unrooted, and installed the update. The update downloads fine, but the with the little Android guy screen, I get an "!" in a triangle and then the phone reboots.
Maybe I didn't remove clockwork all the way? Don't you delete hijack and logwrapper, and then rename the logwrapper.bin to logwrapper?
well basiclly the phone needs to be untouch in terms of the file structure, in my case, I deleted a few of the stock apk files and when I tried to do the update it would fail because the stock apps were missing and the update is a patch not a full system OS so it cant install the default apps, I had to install them back to the system/app with root explorer and then set the permissions back to what they needed to be, unforchenitly a hard reset would not install the stock apps. Also make sure anything that the root touched has been set back to default
I have the same problem too. I can't get the update to work at all after installing Fission ROM. I even restored from a nandroid from a fresh D2G. It worked fine on the untouched phone tho. I checked all the files in the /system/app and they were there. Is there any magical restore .zip perhaps?

I never touched anything... I stopped using Titanium Backup a long time ago when I uninstalled everything verizon and had the same OTA problem you described. I am at a loss for the problem that I have! All I ever did was root and put on clockwork, and I made sure they were gone when I updated.
Please, someone help!
did you uninstall of freeze any of the stock apps in /system/app? You need to restore them in order to successfully apply the OTA update. One file missing or modified in /system and checksums will fail/update fails.

the only time I touched anything in /system was when I removed clockwork by deleting hijack and renaming logwrapper.bin. Can anyone give me a number of files I'm supposed to have in /system, or maybe a way to go back to stock. Man, that SBF would be mighty helpful right now...
There is system dump laying around. I'll PM you the link (not sure if appropriate to post it here). You can use it to compare content and recover missing file(s).

Hi, I've been trying to find an answer, and I think you could help me.
I had the same problem as this person you were helping, but I already knew that I should look through the system dump and compare. I did that, and deleted one file called dbus.conf from /system/ect. Now, my phone just does the DROID animation over and over again! Please help, I made a copy of dbus.conf on my computer and did a nandroid backup. Please, you or someone else on here, HELP!
So you are in a boot loop. If you can't get the phone to boot into clockwork recovery, today is your lucky day! SBF was finally released!!! Get the SBF and reflash /system

Where is it? Isn't it only available to those with some app called TBH (or something like that)? And now I have to wait for a public release? And, if I'm wrong, can you give me a link to thee file? I can't find it anywhere...
Thanks for your help, I really appreciate it!
I would recommend you to approach the team black hat members and talk to them directly about how to get the sbf while your phone is non functional.

But where is the system update located? I checked on the verizon website and there is nothing there. Also, do you have to be a verizon customer to get the update?

Full phone backup without root

Did anyone try to backup the way suggested in this thread?
It'd be great, if it worked: a full backup (apps, settings, everything) without needing to root. I'm trying this right now, but when the phone prompts me to allow backup I tap on the "allow backup" button but it's if it weren't tapped (nothing happens, not even the tapping animation).
Someone tried this?
Edit: it would also allow access to some files that are unaccessible without root...

I've tried by running the various adb backup options manually on Stock 2.21, but haven't had much luck, although got further than you. It will get part of the way through the backup, but silently errors out after a few packages and shows backup complete (when I know it isn't). Removing a problem app just results in it failing on the next one. On my Nexus 7 it works as expected, so there may be a bug in the stock version. Would be interesting if someone with CM or anything non stock could comment.

Agree, would be interesting to see if the issue is related to HTC rom.
I've read on the Nexus 7 subforum that a user is stuck at my same point. I wonder what's causing this...
I had no luck either, although it has been awhile since I tried. I thought I read something on the original documention that made it sound like I wouldn't have any luck. Forget what it was now--
I was able to get this to work with my wifes stock unrooted one s (still on android 4.03 and sense 4.0).
in developer options you need to specify a password BEFORE you start the backup and enter that password on the "full backup" start screen.
i also couldnt get it to create a file for the backup in C:\ so i created a folder, and put it in there, but made sure to check permissions and that the folder was not read only.
I havent restored the data yet, but actually getting the backup file and it being an appropriate size (about 680mb), i would say i am optimistic about the results.
I will report back after i root and update the OS.

[Q] "Can't connect to Camera" with all AOSP Roms

So, I really have no idea what's wrong here. I've tried rebooting, everything. Fixing permissions, flashed different roms, tried different camera apps. Nothing.
Any ideas?

When I was searching for info, I came upon this thread, http://forum.xda-developers.com/showthread.php?t=2187556 seems that some people with the international version of the s3 have the same issue. Might be a good read on a possible way to fix it. If anything, I would revert back to stock and have the phone go through OTA updates to see if it will fix whatever is causing that error.
I fixed it, found the fix somewhere yesterday:
Before flashing, I made a backup of my system with CW
I extracted the SlimISP_ZH.bin from my backup and
copied it to my /data directory and it worked fine.
Link: d-h.st/dwx
(I can't post links yet)

I have the exact same problem with my HTC One. Is it possible for you to upload SlimISP_ZH.bin again to something such as mega.co.nz?

personalize not working (Stock, Sense, 4.0.4)

I went back to a stock rom and started manually debloating it but I deleted too much and now "Personalize" isn't working. I already put HomePersonalize.apk and HomePersonalize.odex back into system/app but I still don't have the app appearing in the drawer and it's not working via settings either.
Can someone tell me what other files are associated with Personalize? (the only two folders I was messing with was system/app and data/data)

Just reflash whatever rom you flashed. Also this should be in q and a.

I see, sorry about the wrong place for this. I would prefer not to flash the whole rom.. it's gonna be a big pain the ass to redo everything I did. Considering I only started removing stuff from two locations I just figured someone would know what files the whole "Personalize" thing uses so I could undo what I did. Like maybe there's a com.android.XXX folder I need to put back perhaps?

If you don't wipe aka dirty flash you shouldn't have to redo much. All your settings will be saved and system apps will be reinstalled. Do you use titanium backup?
Edit: Also, not trying to be a **** about post location, you'd probably just get more help posting in q and a.

AudioFX Issue HELP!!!!!

My OnePlus One has been working fine for two weeks and all of a sudden ive gotten this problem. The sound on the phone doesn't work and neither do YouTube videos. A popup comes up and says "unfortunately, AudioFX has stopped". i press OK but the popup comes back instantly making it virtually impossible to use the phone. this is really frustrating!! please help. before this happened i was trying to do this http://forum.xda-developers.com/oneplus-one/help/speakerphone-volume-low-calls-t2801938
You messed it up, revert back to the stock file. Find the stock file if you didn't back it up.

You said that you were trying the changes from that thread. That thread consist of you changing the mixer_paths.xml file. Upon going in there, you probably changed something that wasn't supposed to be changed or messed up the formatting.
In fact now that I think about it, just go to http://forum.xda-developers.com/oneplus-one/themes-apps/mod-volume-increase-mod-oneplus-one-t2835010 and flash one of the mods. Do note that it doesn't have the earpiece volume change but it will fix your audiofx and will play sound without force closes.
I have had this problem and fixed it multiple times...
The problem is, that for some reason the stock file editor sometimes does not save the full file, then starts crashing, etc. Other file editors seem to work ok.
By the way this can also happen for some reasonwhen applying icon packs or themes.
Now the good part - you can fix it without even loosing you data. You need to flash only the system partition from the stock image. Follow this:
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
But in step 3 apply the command: fastboot flash system system.img
Skip the rest of the steps and apply: fastboot reboot.
You can get adb and the Android SDK tools to use here:
http://forum.xda-developers.com/showthread.php?t=2788632
I disabled AudioFX altogether with Titanium Backup I prefer Viper4android.
