What happened to last_kmsg? - Nexus 6 General

I've been fiddling around with some custom kernels lately and I've had a random reboot or two.... Normally, I'd go take a peek at /proc/last_kmsg to see if anything stood out, but lo and behold... the file doesn't exist.
What's up wit dat? Did they move or rename it? I did a find from the root dir and it didn't pop anything so I'm assuming that its not included/enabled in 5.0.

The kernel Dev has to code for it.

Angry birds restore from AOSP to Sense

Or visa-versa.
I can never seem to get this to work. I back up angry birds with TB, but if I make the backup while running a AOSP rom and then try to restore it after switching to a sense rom, then angry birds FC's or refuses to run or other such nonsense. The reverse is also true, backups from sense rom's don't work on AOSP rom's.
Anyone else experience this? Is there a work around?
Never had that problem. Always works fine for me. Perhaps go into the preferences for TB and verify that the setting for migrating apps across different roms is checked.
Will check that out. Didn't gnow that setting existed.

Ok, where is this setting? I can't find it!

It's under Privacy in the Settings menu.

Ok this is embarrassing. I still can't find it. Went through every setting I could find in TB and I don't see it. Can someone give me specific instructions please? Thanks.

Yeah that happened to me trying to go from CM7 to SkyRaider 4.0. I haven't looked for a solution yet...
Preferences>Migrate System Data
DINC|CM7|INCREDIKERNEL
I went from Virtuous to CM6 before and used TB to restore and had no problems.

Ok, that check box is greyed out for me. Is that because I have the free version?

I found making a backup myself was best. If you copy and paste to your SD Card the following directories...
/data/data/com.rovio.angrybirds/
/data/data/com.rovio.angrybirdsrio/
/data/data/com.rovio.angrybirdsseasons/
You can paste them back later and get all your scores back.
NOTE: I strongly suggest making a new backup of these directories AFTER doing any upgrades to Angry Birds versions because I am sure the data has changed after the upgrade.
You must be rooted to make changes to those directories so if your not, I think there just might be some instructions here somewhere on how to root your device..
Last note: After pasting the directories back (Performing a RESTORE), you must modify the file permissions so Angry Birds can write do that DB file. Otherwise, as I learned the hard way, none of your new scores will get saved..
I am running Virtuous 3.2.0 but I do not think this effects where these folders are being stored.. (I think....)
Grrr. I'm having trouble with this too. I tried to do an adb pull on the data/data/com.rovio.angrybirds directory but it only pulled two files, and didn't preserve the folder structure.
I tried adb shell, and then
copy -r /data/data/com.rovio.angrybirds/* /sdcard/
but it says "can't create symlink..." ??? I don't know what this means
Any help copying these files/folders to my HDD or to the SD would be appreciated.
Yeah I'm rooted, and I did adb remount before trying the stuff above....
I used Root Explorer to copy the folders from /data/data to my SDCard/Angry Birds Backup. (I manually created that folder on my SDCard)
Beware that for some reason, Root Explorer kept building an extra sub folder when copying the files back (overwrite) to data/data/com.rovio.angrybirds... I ended up just copying the single file data/data/com.rovio.angrybirds/files/highscores.lua (for instance) over and that worked for me...
As to the symlink issue, I believe that is a permissions issue. Possibly that you do not either have permission to copy FROM the com.rovio.angrybirds directory or to your SDCard... (make sure you mounted your SDCard correctly) Not intended as a flame or derogatory remark about your skills..
(from searching xda-developers.com)
I KNOW you stated you did the adb remount but was it similar to this:??
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /data
when done, do
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /data
I am close to the limit of my "experstease" here so I dont want to send you down the wrong path or make something worse happen.
I hope this helps.
THANK YOU!
Finally got it working. Ended up buying root explorer and copying over just the highscores file and it works! This has removed my one major frustration with rooting and flashing rom's.
Thanks again for the help!

False alarm, didn't work. I have all my previouse scores and can play the game, but completing a level with a new high score causes it to crash. :-( almost like it can't write to the highscores file properly or something.
-sigh- back to square one.

When you did the copy did you check permissions... sounds like you may not be allowed to write to file.
Just a suggestion.

[DEV] System images

I want to collect the system images in case you must get back to stock.
Just do the following and upload your image.
Code:
su
dd if=/dev/block/mmcblk0p3 of=/sdcard/system.img
perfect would be an nearly untouched build
IMAGES:
WIFI - US: http://forum.xda-developers.com/showpost.php?p=13427976&postcount=7
WIFI - EU: Had to remove my image because of Dropbox
I'm currently uploading one to my dropbox should be done in about an hour. I'll poist the url, or pm you should you prefer.
You may post it in public, of course - thx a lot
seraphimserapis you forgot to ask somthing from the people that upload...
plase add in the first post to add:

Stock?
How would one of these get me back to stock? I've got a corrupt file - so I am bootlooping after root. SU causes a seg fault, so I can't get root permission to remount & replace the busted files... anyone figure out getting to recovery yet?

Use this file http://db.tt/3hqvgP1 and push it to /data/local/tmp
Then run it via ./data/local/tmp/gb
You should be root afterwards and be able to fix permissions etc

borked system/bin us version 16gb
hi I borked my acer. root went smoothly, but then I made mistake of trying to enable adhoc supplicant. I downloaded es explorer and used remount to enable rewrite to system/bin. Now everything disappeared. It will still load, but wifi shows error.
How do I return to stock?

Thank you so much! I got stuck on the Android ! boot screen and couldn't get the OS to boot after stupidly screwing up permissions after I rooted. I downloaded your zip, renamed it to update.zip and loaded it on a microsd card. Then I put the card in, booted the tablet while holding volume down and recovery loaded the system image and I'm back in business. It did come with a few apps loaded into system I'm not familiar with including a few that weren't in English. Will a factory reset remove those, does anyone know?
Edit: This is also missing gapps including the market... You sure this is a US image?
no thats a chinese update u need to follow a link thats been post above urs a bit ago and follow the directions on how to add market to the nook color.

Thanks I found the info. And I bricked it again. Looks like it's getting exchanged at best buy tonight. I'm not going to try rooting again anytime soon.
tonight come in to the irc channel and talk to me. we will get u rooted but not bricked.

Hi and sorry for my poor english...
Could you explain how to put back a system.img backup in the tablet in case of a problem ?
Thanks a lot !
I don't know if that's possible while running the device. This will be good for the recovery tho

wheres hulu

Hulu supposedly works on this ROM, at least is states so:
http://forum.xda-developers.com/showthread.php?t=1264827
didnt see where it said that but i really dont wanna change roms just for huku. on my atrix ni matter what rom i flash i drop my modded flash.so fil in data/data/com.../lib and all flash videos work. this is the fix im looking for.
Sent from my A500 using Tapatalk
you should do the exact same thing that you do on your phone. I have been using hulu since day one using this method. Just search for the modified library.so file and make sure you change the permissions to rw-rw-r (or whatever all the other files in that folder are) you will need some type of root explorer or adb to push the files to the correct folder.
also, you will need to redo this if you reboot. it doesnt persist through a reboot.
Civato mix 3 along with a hulufied flash will run hulu np

I have renamed app_process.

I'm trying to install the update. The update said something is changed in the system/bin/app_process. So using root Explorer I saw app_process and app_process.orig.
Thinking the app_process.orig is the unchanged one. I renamed the app_process to app_process.new.
I was trying to rename app_process.orig to app_process but somehow root Explorer can't so I rebooted.
Now its not booting up. Is there a way I can go to the files without booting up and rename the app_process?

Some custom recoveries (TWRP) will let you browse the files on your device. I know that files can be copied, moved, deleted - I do not know if they can be renamed. My guess is yes, though. If you can boot to recovery go ahead and try that.
If you can't boot to recovery do you at least have ADB access? You can always ADB push the file you want if you do. There are guides out there if you don't know how to do it. I google for a quick refresher every time I have to ADB push a file.
I'm on stock recovery, I can see the device with 'fastboot devices' but 'adb devices' can't see my device? Is this a problem of driver? Or because I haven't checked the developers option? If I can only access the device I can rename back that file.

File manager says granted root, BUT cannot do things like edit build prop??(PICS)

Hello All . I have a rooted 1575 Twrp 3.0.1 I recently noticed iv been getting some weird behavior I havent seen prior. Happens with Stock, AOSP, and CM.
For example with Es File Explorer, I'll swipe from the left , click on tools, then tick root explorer. Ill get the pop up from SuperSU asking me to give it superuser permission, I'll select allow, after about 5 secs, Ill get a pop up saying 'sorry this test failed, this feature can't run on your device', that's the pop up you would get if weren't rooted or if superuser permissions weren't properly granted, But the thing is I am rooted and as the included pictures show, es file explorer says it gas been granted the correct permissions. So I haven't been able to figure out WHY this is happening.
I'm not having any issues with other rooted apps, its only with any file explorer I use.
It allows me to see the root of the SD card, but for example, if I try to edit the build.prop, I'll go in there, make an edit, then when I would try to save it, it won't let me.
When I first rooted this phone, this wasn't a problem. The one change I did make is once twrp 3.0 came out, iv been using adoptable storage. I can't say if this has anything to do with this problem or not, but I'm hoping some one out there has an idea of why this is happening and what I can do to fix it, Bec its so frustrating. Is there something I can do to remedy this.
,
Thanks for taking the time to read this.
