I accidentally deleted some system files from my phones. I want to ask that will restoring my ROM will bring me back those files or is there any other way so you can tell that as well.
The files I deleted were related to sound so now there is no sound on my mobile phone now. I also want to tell you that I am using stock android 4.2.1 rom.
Restoring is your best bet. If you have CWM you can also restore a nandroid, reflash, or factory reset.
If you have a backup to restore that should work. Factory resetting the device will not as it just formats /data & /cache leaving /system the same as it was before. If you dont have a backup you can fastboot flash the /system image from a Google factory image.
thanks
Thank you for the reply.
didn't work
The restore option didn't work. What should i do now?

Did you factory reset before restoring the backup? Yes?
Then you need to start fresh = flash stock through fastboot.

Hey Guys..Verizon GN here. I was curious if someone who is rooted with a custom ROM goes to the Backup and Restore menu and clicks Factory Data Reset, what happens?I'm assuming it wouldnt go back to a factory rom.
you would assume incorrectly. it wipes user data, but does not restore stock images.

Folks, If I wish to restore from a backup taken using recovery after flashing a ROM, is it a simple case of booting it recovery, factory wipe, clear caches, then restore the backup I took prior to flashing ? I'm trying to back out from Revolution HD to get my original APN settings.
Thanks in advance.
there maybe a problem with kernel if u r trying to downgrade.

1) Extract boot.img from the backup on your SD card
2) Boot into Recovery and restore backup (no need to wipe).
3) Reboot straight into the bootloader and flash the boot.img file you extracted.
4) Reboot device.
Have a rooted Gnex with 4.2.1 stock and am trying to update to 4.2.2. Downloaded the image and renamed and am trying to updated via CWM. I initially stumbled on power.tuna.so but was able to move past that by restoring the original. Am now stuck on assert failed: apply_patch_check ("EMMC:/dev/block/platform.omap/omap_hsmmc.0/by-name/boot: 4505600:3db etc...
I am using tiny kernel right now, so I suspect there's someting about this that the update script doesn't like.
Assuming I want to preserve my set up and not completely wipe, what are good next steps?
Someone else correct me if i'm wrong, but i do not believe you can apply an update with a custom kernel.

you're 1000% correct.
OP, you modified /system files and you expect the OTA work? sigh...
As far as not completely wiping, Do you normally need a factory reset when switching kernels? Sounds like a titanium backup or an adb backup [both NOT including system], a fastboot flash of all except userdata.img, wipe caches and dalvik, and maybe a factory reset, then a restore.

I restored the stock kernel with the GNex toolkit and was able to run the update properly.
Hey. I need some help.
My phone doesn't pass the Google screen.
The device worked after installing JellyBam 6.6 and everything was great.
I turned it off after restoring few apps from TB, and then it didn't turned on to the ROM.
Before installing I wiped cache, devlik and data.
I can get to fastboot mod and from there to the recovery (TWRP 2.4.3.0).
Also I can use the toolkit.
What should I do??
It happend to my friend and he told me he wiped everything and installed stock,
but I don't want to format the internal storage as he did.
Should I just install the ROM again, backup and install another ROM?
Should I wipe system?
you restored system apps from TiBu, which is a bad idea.
reflash the rom/gapps then restore your data, but do not restore system apps.
I didn't restore many system apps.
I think only the clock, some app that I made as system one (Notification Toggle), the launcher,
Time zone and few minor things like thats.
Now I wiped cache, devlik and data again.
Should I just install the ROM now or should I wipe system before? (TWRP says it's inly wipe the ROM)
You have the rom in sd rite?
So just go to recovery abd wipe cache and data and system.
After that make a fresh install of the ROM. Let it boot up.

doesnt matter. you restored system apps which can cause problems
wipe, reflash rom, restore only non-system apps/data

Just do a factory reset, wipe cache, wipe dalvik and flash the ROM then the Gapps and reboot. You may not even need the factory reset though. Try without it first.
Already did factory reset..
What is system reset and when I need to use it?
If it's wiping the rom, shouldn't it done before changing one?
OH, I just realized I deleted the ZIP file from my device.

I've never done a system wipe. But I assume it wipes EVERYTHING. Meaning if you do that, you better flash something right after so you have something to boot to. Otherwise it will never boot and you will have to hook it up to a computer and flash a stock image and start over. I dont know if wiping the system will wipe your SD card as well. If all you did was changes some system apps and data around then a simple re-flash of the ROM should fix it. If its not then I'm going to say that there is something else wrong.
I don't have to ROM.zip on my device.
Can I somehow do this using Fastboot Mode and my PC?
I tried with OTG and DOK but it's not working :X
boot into recovery and use adb to push the rom to your device.
adb push c:\yourlocationofrom\rom.zip /sdcard/
Okay, I did it, but I can't find the file..
It says that the file passed..
I did "adb push D:/JellyBam.zip \sdcard\"
Where did the file moved to?
OK, got it!
I tried again with upsided / \ and it works.
THANKS A LOT!
working
So I shouldn't restore any system app?
Not even data?
And what about SMS, data usage and stuff like that?
Apps that I made as system app (Like notification toggle)
Launcher??

It depends on what ROM you were on when you made the backup. Are you coming from a different ROM? Because thats when you should NOT restore system stuff. Thats like trying to add stuff to the system that is not meant for the ROM. It doesnt take that long to set up all your settings manually. I would just stay away from restoring system stuff with Titanium Backup. There are apps that backup and restore your sms messages in the Play Store that work well. What launcher are you wanting to restore? If you made any app a system app previously, I would just restore it as a user app and THEN make it a system app again. Dont restore it directly as a system app. And before you do anything, make a backup of your ROM so you dont have to go through all this again.
I restored few things, but Data only.
Now there isn't a problem.
THANKS again for helping
Well i wiped dalvik cache and cache only and now stuck on sasmung logo?? How much time davlik need for rebuilding or I need to restore all backup (waited 15min and nothing)? The all backup restore didnt work too...So factory reset is next right?
The factory reset worked but when restoreing backup its the same thing. Pls help where could be the problem in backup (system,boot,data...)

Really no idea, maybe some file corrupted.
You can use odin pc to install stock rom. After successfully reboot then root it and do restore again.
Good luck.

What do you want to restore? Did you already have Perseus kernel when you did the nandroid backup?
How did you made backup?
:*: Neebi :*:
maurice srefmen
Yes the persus kernel was instaled when i did nandroid, I used cwm backup to external card, tried to restore one by one but when restoring data i get stuck. I whant to restore everything, thats way I did backup before wipeing dalvik. So only left is flash stock root and try again?
Which error message do you have? Did you move or rename your backup?
Try to go to advanced settings and restore data only.
No error just stuck at boot logo, I tried every combination with system,boot,data restore but nothing, then I restored eariler backup without persus kernel in it and it worked (reverted back to stock kernel) then instaled persus again and its all fine now :good: Do you think there is some problem with backuping when persus kernel is installed?
I didnt now that factory reset with cwm doesnt erase sd internal so I have everthing back in place. Tnx everyone
Nice :good:
I know that we can have some issues when we try to restore a nandroid created from another kernel but nothing special but the Perseus kernel.
But AFAIK there is less problems with TWRP than CWM so it's possible that your problem is a recovery one and your custom kernel doesn't matter. Just try TWRP and let me know
EDIT
Factory reset only erases /data and /cache folders
I tried with TWRP and no problem with backup or restore :good: tnx
