I have rooted my KF，and changed some system file.
I tested “Reset to Factory Defaults” in setting. But some files in /system still unchanged.
How to restore Kindle fire official ROM Just as the factory？？？？？
Thanks very much for all！！！！！
First of all, seriously? In the dev section? Second, did you even look first?

Evening all -
I have an easy question - I have read the unbricking / restoring your KF thread and numerous other threads on the web about restoring a KF back to the factory state.
Let me start of with a few things
1) there is nothing wrong with my KF - it works great
2) I was rooted prior to the 6.2.1 update and Android Market is installed etc.
I am considering selling the KF for a different tablet but I want to ditch all applications, all SDCard information and anything remotely related to rooting.
If I use the "return to factory defaults" in the Device pull-down, will it do all of the functions listed above or will superuser .su stuff and SDcard stuff remain?
I just want to wipe it clean.
Thanks-
Benjamin

I suck
Im on cm7 and I want to go back to Stock kindle fw, how would i do that? Cm7 is awesome but i wanna use prime for my free month and hulu+ and netflix are out of sync :/
Did you create a backup beforeyou flashed CM7?
Yeah, where would it be saved? Would i flash it with twrps the same way i did cm7?
You should boot into recovery mode and do a restore there...but i dont know if you need to do a wipe first...i would wait for a more definite answer from a more experienced user...
there are allready some threads/guides about this:
if you want pure stock:

and yes you do it the same as you flashed cm7 including the davlik/cache cleaning things
just the same - see here:

guys please use the search function !
I just got a used A500. How do I do a full master reset so I can make it like I just opened it up new. Thanks guys,
Go to settings>Privacy>factory data reset...
There's also a reset button on your device Or has this button another function?
Yes however I do believe that this does not clear the internal SD storage. I too wonder about the op`s question. How does on completely reset the tablet including the internal sdcard.

If you do this and the previous owner had deleted phone.apk and telephonyprovider.apk from /system/apps, then it'll get stuck at the logo when rebooting. Check to make sure those files are there before doing a factory reset or data wipe.
Also, Check to see what ROM is on it. Is it stock? or is it a custom ROM? If a custom ROM, then to make it new you'd have to install STOCK.
So it comes down to how NEW you want it.
There's a thread that discusses downgrading to 3.01 using nvflash. That's the most sure way of putting back to factory settings, without knowing the exact status of it currently.
The easiest method probably is to just install a custom or stock ROM with a data wipe. But you need to do a little digging to find out if your on the old bootloader or new one and weather or not the tablet is already rooted.
As the title says, I'm getting notifications to upgrade my Nexus 7 to 4.2 even though I have 4.2 already. If it were the 4.2.1 update that it wanted me to update to, wound't it say 4.2.1 instead of 4.2?
Info on the device:
Rooted
Bootloader Unlocked
Stock ROM
I went ahead and tried installing the update many times and while it shutdown to do its dirty work, it eventually error-ed out (while the little Android guy is on his back). I have even done a factory reset and I still get the prompts to update to 4.2... from 4.2. Errors are there as well. Thank you for your help.

This has been posted about before.
Yes, the 4.2.1 upgrade says "4.2" in the update screen. Your device is trying to go from 4.2->4.2.1.
The upgrade however seems to be failing. Since you are using a stock recovery, there is no indication on what part is stopping it. It could just be a glitch or, more likely, you modified something. Did you install any mods or root and modify any system apps? Freezing them in TiBu/etc. will break it too.

I did read other posts but they didn't seem to help.
After I rooted the device, I went ahead and pasted the original browser.apk in the System/App folder and installed it from there. From what I read, that was most likely my problem. I deleted it but still got the error. After that I said "screw this" and applied a data factory reset thinking that would solve my problems
Thank you for your reply.

Yes, that modification would certainly break the OTA update.
Doing a factory wipe won't help. That won't revert the old system apk back to stock. Nor will deleting it.
Your best bet is to download the full 4.2.1 image and flash that. Or, you could find and restore the original browser.apk.
This should serve as another reminder to people who make tweaks - always backup the original file!

It's not that bad. Everything works fine except for updating the thing. As for the restoring the original browser.apk, if you mean Chrome, I never touched it so it is there.
My guess is that I didn't install the CWM Recovery correctly because I can't boot into Recovery Mode. It just hangs and stays in a loop. I will re-install CWM and see if that helps.
John J
Re-installed CWM Recovery and flashed 4.2.1 from there. Lost everything but I had anything important backup already. All is good
So, to my new found knowledge I made a big mistake.
I rooted my Nexus 6P for the first time ever, and I used the Nexus Toolkit to root after failing miserably via the classic method. After I rooted I installed some minor tweaks and I then decided to step it up and install lineage OS. I installed it with not much problem. I tried installing another slight tweak and I saw the message of "System UI has stopped". I panicked and factory reset and am installing again to the first version of Lineage I tried (which worked). I then started thinking...
If I want to uninstall lineage how do I get back to my stock OS?
I then saw all the forum posts on other devices and they all said just install the old ROM you backed up.
Guess who didn't back it up.
I wanted to see if there was any way I could get my stock OS back, I don't care if I can or can't sync my app with Titanium backup I just want stock back. I would've posted this in anohter seciton but since im new I thought I would put it in general rather than other less fitting subsections.
You can always go back. Just download the factory image and use adb to reinstall a fresh factory install.

Easiest thing to do is download the stock OTA from Google and simply adb sideload it via adb sideload command on your pc. Also I recommend trying different roms than lineage as many roms are based off it but with added features and improvements. I use this rom which includes the opengapps package for Google apps like play store. I recommend wiping everything and going back to stock and trying this rom or another one of your choice.
