[Q] Shot self in foot, edited build.prop now N7 won't boot

I was testing tablet UI mode by editing the /system/build.prop file. The N7 went into Tablet UI mode OK but I didn't like it so I reedited the /system/build.prop file to undo my edits, and now the N7 doesn't boot properly. It goes to a black screen and just sit there.
I can boot into recovery and I can get adb to work. I used the pull command to get a copy of the build.prop file and it seems OK but I'm not 100% sure if I made any other edits by mistake. Of course like a fool I didn't make a backup of the original.
Can anyone make some suggestions on how to fix my N7?
Thanks.

reflash your ROM. it'll replace your build.prop with a good copy. don't wipe a thing, just reflash.

I'm rooted but on stock. Can I just download a copy of the stock rom and flash that with CWM?

rooted stock ROM yea. I've also flashed a pure aosp ROM over stock without any reprocussions.

Before I go ahead and reflash I just want to make sure I'm getting it right. I've downloaded the stock rom, extracted image-nakasi-jro03d.zip. I should push this file to my internal storage, then use CWM to flash? Or should I just find a pure aosp ROM and flash that?
Sorry for all the questions, I just don't want to make things worse.

I don't know what you picked up, but here's a stock/rooted ROM that you can flash in your cwm recovery http://forum.xda-developers.com/showthread.php?t=1776330
Aosp works too, its your choice

if you know how to use adb you can just boot to recovery and push the stock build.prop to your tab

I downloaded a stock copy of the stock build.prop, used the adb push command to push it into /system rebooted and nothing. Still hangs on black screen upon boot.
I then downloaded the stock ROM which simms22 kindly pointed me to, used the adb push command to copy the zip file into /data/media/Firmware, used CWM v6.0.1.0 to "install zip file from sdcard" and I got an error, here is the output:
Installing:/sdcard/Firmware/Nexus7 - JRo03d-Odexed-ROOT_4.1.1_signed.zip
Finding update package...
Opening update package...
Installing update package...
E:Error in /sdcard/Firmware/Nexus7 - JRo03d-Odexed-ROOT_4.1.1_signed.zip
(Status 0)
Installation aborted.
I tried both the Odexed and Deodexed files, both gave same results.
Am I missing a step in the process?

It's working now!
I was afraid I was messing up some of the adb commands so I downloaded the Nexus 7 Toolkit 2.0 (Great tool for someone like me)
- via Toolkit re-transferred the odexed and deodexed ROM files, reflashed, same errors as above
- via Toolkit re-installed CWM Recovery 6.0.1.0, reflashed, same errors as above
- via ADB Shell used CHMOD to modify file rights of the ROM files (stab in the dark), same errors as above
- downloaded stock image from CWM site (JRO03D_grouper.zip), pushed via tool kit, flashed via CWM....WORKED!!!
Everything is as it was before, no need for a full wipe! I'm going to do a backup right now!
Not sure why the other ROMS would not flash, but at this point I'm not going to mess around to try to figure it out.
Many thanks to simms22 and PhxkinMassacre for getting me pointed in the right direction.

prly a bad download.
after pushing the file you need to set the correct mode:
Code:
adb shell chmod 644 /system/build.prop

Me too - also hosed my own build.prop

Ok, I did the exact same thing and followed these instructions but haven't had any luck.
First, thanks lbloo and the folks who have responded for all the info here. I have downloaded JRO03D_grouper.zip and I am grateful for the tip to the toolkit.
When I have pushed JRO03D_grouper.zip to the N7, it appears to have worked, but I can't find it on the sdcard. I am pushing from the default location to /sdcard/. I then select "install zip from sdcard" and "choose zip from sdcard" but the only zip there is supersu (from Day 1).
For reference, this is CWM Recovery v 6.0.0.6.
Thanks in advance for any help anyone can offer.
Jack

Looking back I don't recall resetting the file rights after modifying the file and that was likely the root cause of my problems.
You should try the chmod command a couple of posts back.

Yes. And, to further test, I created a little zip file called test.zip and pushed it to the tablet. I can see it just fine. It's just the grouper zip that I can't find.
Thanks
Jack

I just noticed a diff in filesize between the JRO03D_grouper.zip file I am using and one shown in a Youtube video entitled "how to put a rom to flash on a semi-bricked nexus 7 with recovery" by Youtube user metroid031993. (I'm too green to post outside links on XDA)
Mine is 261814702 bytes, the one shown in the video is 32650144 bytes.
Perhaps this is my problem, an invalid zip file. What do you think? And, can someone please tell me the correct size of JRO03D_grouper.zip?
Thanks

Well, I got the grouper zip into /sdcard/ and was able to upgrade without losing anything. w00t!
Theory:
I was in the same adb "session" this time since I was using adb from the command line. Meaning, the daemon was still running from the first push I did. So, while I couldn't see the grouper zip after the first push (consistent with your experience, dark_samus), I could see it and upgrade with it after second push (also consistent). And, perhaps my previous attempts didn't work before because I was closing and opening the Nexus 7 Toolkit each time, therefore stopping and restarting the daemon, which meant that each push attempt was the first attempt for that "session."
I don't have any solid technical basis to support or refute that theory, it's just one possible theory that, if true, would result in the experience I had.
My problem is resolved. Thanks to everyone who contributed to this, I truly appreciate your help!

Either replace the complete system partition using 'fastboot flash',
or, probably less intrusive, boot into recovery mount system partition writeable and push build.prop manually using 'adb push'.

That's because you are using a custom recovery. You can either flash a stock recovery or edit some files in the zip so you can flash it in the custom recovery.

Possibly, but probably not. In most of the reports that have been coming in - when the users actually report the full error message rather than saying something ambiguous like "I got a Status 7 error" - the problems revolve around altered/removed files in /system, or having a custom kernel (boot or LNX partition) installed. That suggests that the recovery version is not causing assert() failures.
The other thing to rememder is that the program that is interpreting the edify updater-script is the "updater-binary" program which is shipped inside the OTA - so it is virtually identical independent of the choice of recovery (other than perhaps kernel behavior differences).

Even though what you are saying here does only require being able to operate a plain-text editor and a zip tool, it's way above the heads of most folks who think that OTAs should work on non-stock ROMs. And I'm not sure how these folks would be better off with partially-patched ROMs. In any event, if this course is taken indeed a custom recovery would need to be used for this, as modifying the zip contents will break the OTA package signing, so the stock recovery couldn't be used.
The OP should just
- make a full nandroid backup of what they have now
- download the factory 4.2.2 images from Google
- extract the system.img file and boot.img images
( hint for windoze users: 7-zip understands .tgz files)
fastboot flash boot boot.img
fastboot flash system system.img
- reflash a basic SuperSU or Superuser root kit
Sort of crude, but it's a decent hack for the lazy or poorly informed. It won't "erase my data", but presumably it will break whatever it was that altered the stock system and/or boot partitions - the very things that are causing the OTA to fail on them with their rooted & modified ROMs.
If they don't like the result, they can simply restore their nandroid backup.

Maybe the zip file is corrupted. Try to download it again.
Or maybe CWM has some problem, idk, I prefer TWRP (MultiRom version to be exact).

You can search for the super su fix and download from somewhere else its only needed for rooting the rom

Download SuperSU directly from Chainfire's site - http://download.chainfire.eu/supersu

So, just to be sure because i've never done this procedure for rooting before.
After flashing the rom, xz dualrecovery and update-supersu zip files, i use flashtool to flash the .ftf file and uncheck all wipe data boxes, and exclude everything except fota,kernel and baseband, am i correct?
It's the last part with the exclusions that i didn't get completely right..sorry if i look like an idiot :cyclops:

i get error extracting update-binary if i remember correctly...
anyway after trying some other methods, i managed to unroot my phone..
I'm gonna try your method again, since my phone is kinda messed up now..

flashed the zip but got an error during setting permission
now wifi does not work anymore

same here, just tried again..
set_perm: some changes failed
E:error executing updater binary in zip
Error flashing zip...
Failed
About the wifi, i think it has something to do with the flashtool exclude options..when i tried with this method http://forum.xda-developers.com/showthread.php?p=50234676
wifi worked fine, i had root but some weird issued occurred as i described in the above thread..
and after i tried for a second time, i lost root...so i am back from the beginning...
just to mention i have lb, but i guess it doesn't matter when flashing stock kernels, right?

its going to crash out on
set_perm(1002, 1002, 0440, "/system/etc/dbus.conf");
as there doesn't appear to be a dbus.conf in the zip.
as the remaining permissions then aren't set it could well be why the sensors and wifi etc don't play nicely.

the phone is rooted but I haven't installed any custom recovery.
I thought i could be possible to grab someone's backup system archive and use the xdabbed apk to restore default applications.
Actually I should describe a bit more the problem, the camera is there, the player is there but the gallery has disappeared.
There is an LGgallery.apk that comes with xdabbed package but i can't install it. When I try a manual install (just launch the apk), it is just telling me that the app couldn't be installed.
hope we can do something from it, otherwise I'll install a custom recovery and follow any advises you might have,
Thanks,

The thing is:
I can provide you with a restore package(also apk) but I wouldn't advise it. (it's unsafe replacing files on a LIVE android system)
If something happens and you don't have a custom recovery then your only solution is to flash a kdz.
So the best thing would be to install recovery.
If you want the apk I'll send it to you, until now it worked 2 of 2 times for restoring. Again..i would advise the recovery.
+you don't install the lggallery.apk, you copy it to /system/priv-app and chmod 644
first delete the lggallery.odex

Ok so i replaced the old LGgallery, remove the odex, changed permission and reboot but no luck with that.
installing a custom recovery sounds quite complex and I am ready to take a risk and try your archive. (hope it'll do the trick)
Otherwise I'll resort to install a recovery,
Many thanks

Actually it's 1 click and it's installed. If the apk fails and you bootloop then you can't install recovery(or boot).

Since you are already rooted.
first: download this
It's the flashable zip for the camera(thx to bruce) (put it on sdcard(internal storage))
then
1. AutoRec d802 You say you've got the d802 right ? Then this one.
Install..Run..Press YES. Allow permissions. Press Flash, wait.. When it says it's done then it's done.
Then press "to recovery" see if it reboots. If it does, you should see TWRP..just press install zip, choose the newly dloaded file.
