Boot troubleshooting - Nexus 7 Q&A, Help & Troubleshooting

After working without a glitch for four years, my Nexus 7 (grouper) got stuck in a bootloop after I started it today. Thinking that something is probably wrong with cashe or dalvik cache I've cleared them. Now the bootloop is gone, but the device gets stuck on "Starting apps" after it finishes "optimizing" (filling in the dalvik cache). I would like to see what's going on but I have a problem doing that.
The problem is that I can't get the logcat to do the job. I've tried two "solutions" that seemed obvious, but (for some reason), none of them works.
First "solution": make a simple script and put it in /system/etc/init.d/:
#!/system/bin/sh
logcat > /sdcard/log.txt (set to 755)
I get the file, but even if I leave "Starting apps" to run for some time, when I turn off the tablet and look at the file it only has 65 lines and it still didn't finish initializing the hardware part. No information about started apps or anything. I can retrieve dmesg log from recovery but nothing interesting there as well.
Second "solution": I've tried to make it work trough init.rc, by following this https://stackoverflow.com/questions/17406209/enabling-logcat-in-init-rc (switched /cache/ to /sdcard/). But this also produces no results. Txt file is not generated at all
I don't know what I'm doing wrong.
I don't want to do a factory reset unless absolutely necessary (bunch of games with save files and other apps as well).
I can't do logcat trough adb since device is "unauthorized".
Any help is appreciated.
Thx in advance!
P.S. Using OmniROM (4.4.4)

Boot into TWRP and see if you can create or edit a text file. Reboot back into TWRP again and see if the change you made is still there. If it isn't, your flash memory has gone bad and you are in read only mode. This cant be fixed without a new motherboard. Hopefully this is not your issue.

Sorry for the late reply, I was on vacation and I left the tablet at home.
The script I've mentioned was inserted trough TWRP so I think this confirms that you can write.
Also there is a log file created, as I've mentioned, it's just super short (I guess if it's in read-only mode there would be no output).

mmcblk0p1 I/O error way to retrieve data

well, i got the dreaded "can't mount /dev/block/mmcblk0p1" error, and decided to try some stuff i learned since i had some important photos/videos from a recent trip on there. turns out it worked, and figured i'd share with anyone (although it seems this error is fixed with the latest software). i recovered everything off my phone, totalling to approximate 1.7gig.
flash a adb recovery ROM with SU (can't remember if the SU is necessary, but there are pre-rooted roms out there, i just used one). also make sure all the drivers for the phone are installed on your computer
adb shell
su
echo /dev/block/mmcblk0 > /sys/devices/platform/s3c-usbgadget/gadget/lun1/file
with winhex, open drive. a directory browser will show your file structure, and right click-->recover/copy whichever files you want. i went a step further created an full image so i can send in the phone. now i have a complete backup i can go back too at any time in case i forgot something i needed.
i tried re-flashing this phone with jg8/jh2/jk3/jl2 with different PITS trying to bring it back and nothing. tried force mounting it and some other commands, but in the end, this worked.
somebody should give this a try.
great work
i could've really used this had it been a month ago, before i sent it in and lost everything
hey Ziostilon, when you had your phone fixed last month, did they mail you a new phone, or did you bring it in for repair? these Bell guys are breaking my balls and saying samsun can recover all my data, and i have to send it in for repair for a month
edit: it looks like this worked because the data on the partition is still intact, just the partition table is messed up. i wonder if a program like partition magic can repair the partition in it's current state? it might be something to look into for people without a warranty.

[Q] Stuck on splash screen

Good evening everyone.
To start with, yes I've read all the similar topics and none of them helped me
To my problem now. My phone has been flashed with a custom ROM for 1-2 months now (I don't remember exactly) and this morning I woke up to find my phone turned off. While trying to turn it on, no matter how much time has passed, it's stuck on the splash screen refusing to load the home screen
Is there any suggestion that does not involve me losing all my data because I have no backup of them?
Waiting for any suggestions.
See if you can connect with usb, and adb can communicate with device.
If yes, you can save the /data/data folder(in which are all configurations) + /data/app folder(in which are all apps except these on sdcard if any).
You can also run adb logcat from command prompt and see if you can find what app causes the error and the bootloop, and if maybe you can uninstall/reinstall this app, or delete the folder of that app on /data/data folder, to hopefully solve the error.
Try to install a program like QtADB, droid explorer or Android manager to avoid use command line and simplify some of above operations as copy/delete folders or install/uninstall apps.
If you need more help, PM me to speak in greek(it' s better)
I've just installed QtADB and connected the phone while being inside ClockwordMod v4.0.0.5.
The truth is that from here I don't get almost any useful information (don't know why). One positive aspect is that I can copy data from/to the phone.
While stuck in the splash screen I can't connect through adb though.
You mean not at all? Usually when appears IDEOS screen you can connect via adb, after some time and when the error start maybe the device freezes and then adb probably disconects, but until then you can take some useful logcat info for the error.
You can also have some more functions with QtADB on recovery mode if you mount the partitions first.
Maybe and the app manager work then(I haven't tested though).
Managed to get logcat information while turning on the phone. I'm attaching the log file with the error lines.
Trying to read them right now to find a solution. Any help appreciated.

By reading your log i think the problem is permissions. Try to fix permissions with recovery tool.

Recover from FireParted Bad Partition

Last night I tried to use FireParted to change the partition on my Kindle Fire but ran into issues. Reading the thread was not clear on what happened and how to fix it. But I finally figured it out based on several sources and wanted to share how to solve it.
It seems that FireParted partitions your SD card but screws up the cache and userdata partition. It does not brick the KF and you can recover. You'll need to boot into custom recovery (I used TWRP) and and use ADB to manually create the partition.
Step 1: Boot into recover mode.
Step 2: In command prompt go to your adb folder of Android SDK tools (platform tools)
Step 3: Type: adb shell
Step 4: Type: parted /dev/block/mmcblk0.
Step 5: Type: print. This will now show your partition. You will most likely have partition 10 (userdata) and partition 11 (cache) missing. You'll need to create those partitions
Step 6: Here you can follow instruction for creating the partition from eldarerathis thread. Start with step 3.2 to the end but don't reboot yet.
Step 7: If you saved your data using FireParted then after fixing partition you can fire up FireParted again and use the restore to get your data back. You can now reboot and should be back to normal. Hope that helps.
Credit: Most of the work was figured out by eldarerathis with the manual partition.
Ideally I'm going to add a few changes to allow FP to try to backout changes if the SD card resize doesn't work, but it's been hard to debug/test since the error doesn't occur for me and it's become something of an "inexact science". I still can't make the SD card constraint error appear without very purposefully causing it, but I'm inclined to leave the FP thread up anyway for now (without links to the binaries, though I haven't deleted them from Github) in case anyone else wants to poke around in the source.

Are you on a custom ROM on the KF. Reading through your thread it might be the stock ROM that is having these issues.

I use a stock rooted ROM on mine, the same one I post in my threads.
I'm going to try to install a couple of different ROMs this weekend to try some of the changes I've been making (since I think I'll have some free time) and see if I can reproduce the error with any of them. If I can at least do that then I might be able to pin down some sort of commonality.

One message I got before it tried to partition and got stock was the regarding the "e2fsd" saying that it might need to be updated. The message showed up twice before it begin the attempted partition and got stuck. I hope that helps.

How do I copy files from Nexus 7 to my desktop?

I read the threads concerning about this problem but I seem to be only one to have it.
So this is what happened
- I was running stock 4.2.1 rooted with CWM Recovery, awesome
- I see CyanogenMod 10.1 is available, even better lets flash it. It was a nightly version but ok I have never had problems with nightlies
- I make a Nandroid of my stock ROM
- Factory reset, clear cache, dalvik
- Flashed CM10.1
- It booted fine, but first thing I see is "Setup wizard has stopped" , "process com.google.xxxxxxxxxx has stopped" - basically I can't do anything
So I get back in CWM, clean everything again, flash it again since I thought maybe something went wrong when installing it. I got the same problem, again, I can't do anything. So I get back into recovery thiniking I can recover my Nandroid.
Well, no, since I suppose everytime I factory reset, all the files on the Nexus get moved into a new "0" folder, and usual folders like DCIM or ringtones get created too. So I basically have 4 of those. My files which were previously on stock ROM are all in
Computer\Nexus 7\Internal storage\0\0\0\0
Naturally, CWM thinks my backup ROM is in Internal Storage - clockwork mod so I can't recover the ROM.
Logically I decide to move the clockwork mod folder to a place in which recovery wants it. This is where the problems begin. I can't copy anything from N7. Windows explorer creates empty "copying" dialogue and doesn't do anything, or says that it is "calculating time required to copy files" (Windows 7 Ultimate 64 bit)
How do I copy files properly, or at least - how do I restore my ROM?
Thanks.
Use the "adb pull" command?
Maybe adb shell cp /path/to/nandroid /where/you/want/to/move/it
Use cp -r if the android is a folder, sorry its been a while since I checked on mine
Thanks for your replies. In the end, before I saw your answers I raged and just left it to "calculate time" or whatever, and to my surprise when I got back it was copying. I guess it needs time. Thanks though, I hope someone finds your answers useful.

XPosed is OPTIONAL, but there are a lot of rooted apps that use the XPosed framework to get more control over your phone. Such as hiding mock locations for example.
NOTE: Internet is REQUIRED for KingRoot to function (grants temporary root, so ADP commands can be executed to unlock bootloader), at one point WiFi will NOT function but internet is still required. So a valid SIM with internet is required (Verizon will definitely work, others might[/] work)
NOTE: The entire installation will take an estimated 1-2 hours. (Not including time spent downloading) All steps are MANDATORY, do not SKIP anything....You've been warned
Install eMMC Brickbug Check (free) on your phone, and RUN IT. Your CID MUST start with 15. If it doesn't I can't help you, and this guide is not for you.
Install the Samsung USB drivers on your windows PC
Backup your phone, if you don't know how.....google it...And learn how, you will want to backup frequently. Every time you get to a point you can boot up into Android, backup...it's safer for you...I will not remind you again, this is on your head.
Disable Encryption on your phone, both the SD card and Device
Disable Samsung Phone Lockout. YOU MUST DO THIS OR ELSE!!!! (Settings > Security > Reactivation Lock)
Do 2 factory resets on your phone, one after another (hold volume up, home button, power when starting to enter recovery mode where you can reset phone). Not required but if you don't, you'll spend an extra hour or two doing this because Kingroot will crash/fail more often.
Boot up your phone in Download Mode (hold volume down, home button, power)
Open Odin3, Click the AP button and select the file N910VVRU2BPA1_N910VVZW2BPA1_VZW.tar.md5, once it checks it, goto options and make sure the Re-Partition is NOT selected. Now click start to flash and downgrade to Android 5.1.1.
Turn on your phone, and let it boot up.
Skip everything possible when setting up your phone. Don't even put in a google account, not necessary
Goto Setings and set the following
Settings > Security > Reactivation Lock = Disabled (EXTREMELY IMPORTANT, VERIFY)
Settings > Security > Unkown Sources = Enabled
Settings > Developer Options > USB debugging = Enabled
Developer options are unlocked by going to Settings > About Phone. Find "Build Number", and start clicking it till you get a message that Developer Options have been unlocked (about 10 clicks I believe, never counted).
Settings > Developer Options > Verify App via USB = Enabled (should be by default, CHECK)
Settings > Lock Screen = None
Settings > Display > Turn off Display = 10 Minutes
Plug your phone into your computer via USB, copy the NewKingroot****.apk to your download directory (samsung-sm-N910V\Phone\Download)
Install ADB onto your Windows PC. Select an easy directory such as c:\ADB
Copy the following file directly into the ADB directory
samsung_unlock_n4-fix
Open up command line interface. Hold windows key & press R key for run, type in "cmd" press enter. Will open a terminal window for you. Type the following commands:
cd\
cd adb (or whatever you named your directory where you installed ADB)
adb devices
This should return a list of devices you have connected, something like:
Code:
List of devices attached
SerialNum device
If no devices are displayed, check you have the Samsung USB drivers installed properly.
Type the following command
adb push samsung_unlock_n4-fix /data/local/tmp/
Got an error? check your spelling (or copy/paste from me), check you put the file into the ADB directory (not just a link), your phone must be on and screen not locked and check you have usb debugging enabled.
BTW: Do NOT CLOSE the window unless I instruct you to!
Install Kingroot on your phone, which you previously moved into your downloads folder, you can find it via My Files app that comes with phone.
Now run KingRoot. Flip down to the bottom and click "Try It", it will run some quick test then give you a button to try to root your phone.
Wait...Wait...Do not worry if your phone restarts, it will go back into KingRoot automatically on reboot. Just sit back and wait, it may fail multiple times and you may have to re-run Kingroot. Just keep trying . Once it succeeds you must do the following IMMEDIATELY AND AS FAST AS POSSIBLE. Kingroot is HIGHLY UNSTABLE.
On the windows PC, back in the command window you left open. Start Typing.
adb shell
su
cd /data/local/tmp/
chmod 777 samsung_unlock_n4-fix
chown root.root samsung_unlock_n4-fix
./samsung_unlock_n4-fix
After the last command it may prompt you to type yes, do so immediately. it won't write on the screen but type yes anyway for it to continue. Once it's done it should automatically start to reboot your phone. Unplug it and pull the battery, wait 5 seconds, put battery back in and plug the phone back in.
This was the initial setup for unlocking your bootloader, you now have to run it AGAIN so turn your phone back on. Repeat steps 22-24, after the 2nd time PULL OUT YOUR SD CARD BEFORE TURNING ON YOUR PHONE
Congratulations you now have an unlocked bootloader, you can close the command window on your PC.
The SD card has a restore point for your phone prior to removing your bootlock. Save it if you want, or plug into your phone and format the 18mb partition you are able to. You must format it on a PC before you can use it again in a phone!!!! Will shut your phone off immediately if you put the SD in without formatting that 18mb partition.
Now reboot your phone into download mode (hold volume down, home and power buttons when turning on)
Open Odin App on your PC, Click the "AP" button and select the file twrp-3.0.2-0-trltevzw.tar.md5 (which you downloaded earlier). Once it does it's check, verify that re-partition is NOT selected in options. Now click start to flash twrp bootloader.
Your phone will restart, re-enter download mode. If you missed it pull cable/battery and try again.
Now extract and flash N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar.md5 via Odin, same as you did with twrp. VERIFY THAT RE-PARTITION IS NOT SELECTED IN OPTIONS.
Boot up in recovery mode (hold volume up, home and power when turning on) (note: no longer TWRP since you flashed firmware, will look different again)
"Wipe data/factory reset ", then reboot your phone.
Now repeat steps 9-12 (NewKingRoot should still be in your downloads, but verify anyway) (NOTICE: wifi will NOT work with the CPD1 firmware, but Verizon internet should in case you need internet for some reason, wifi will restore later in guide - Other internet from other providers MIGHT work with proper APN settings)
Install a clean SD card into the phone.
Now repeat steps 15-25. This time you should only need to run the samsung_unlock_n4-fix file once to break your boot. This is what it typically says on successful bootloader unlock: (if you got this message, pull the battery, cable and SD card.)

Now boot back into download mode
Flash TWRP via Odin again (I'm summarizing greatly now, as you should by now understand this kind of shorthand)
Ok, now boot up into TWRP recovery mode (vol up, home, power)
Navigate through TWRP menus to create a Backup. Click Backup Button, and swipe to create backup. (this is just so that it creates the directory structure on your phone)
Click the Reboot System button, skip all the setup you can again. (DO NOT INSTALL SUPERSU!!! will cause bootloop)
Extract the "JasmineROM_v7.0_N910VVRU2CPF3.7z" file it will create a directory called "JasmineROM_v7.0_N910VVRU2CPF3".
Plug USB into phone and to computer. Copy the JasmineROM_v7.0_N910VVRU2CPF3 folder into \Internal storage\TWRP\BACKUPS\Phone SN\
Reboot into TWRP recovery
Click the Restore button (DONT start the restore yet!!!), and check that your JasmineROM is listed as a recovery option. (don't recover YET) If it's not there you copied it into the wrong directy, try again before proceeding.
Go back to the main menu, Click the Wipe button. Click the 'Advanced Wipe' button, and wipe the following cache/dalvik/system/data
Go back to Restore (from 2 steps ago) and run the JasmineROM_v7.0_N910VVRU2CPF3 recovery, return to main menu afterwards
Go to wipe, and wipe the cache/dalvik only this time.
Reboot into download mode
Flash the N910VVRU2CPF3_PartialFirmware_PatechedKernel.tar.m d5.7z file via Odin
Reboot the system, this will take a LONG TIME. WAIT for it. (if reboot takes >10 min, pull battery and restart)
Once it boots up, skip all the setup again. Copy the CM13, Gapps and XPosed (both zip and apk) to your downloads. Don't unzip anything, not necessary.
Now reboot into recovery go to WIPE and do a factory reset by swiping.
Then goto Install (still in recovery) and install CM13, then Install Gapps.
Reboot your phone, this time you are setting up properly reboot will take a while to optimize your apps depending on Gapps version used. So do all your setup as you want your phone setup. Once that's done, restart the phone in recovery. (if reboot takes > 5 min, pull battery and restart)
Install via TWRP the XPossed.zip file.
Reboot your phone, once on. Navigate via My Files, to downloads and install XPosed.apk
CONGRATULATIONS. You now have a fully Unlocked, Rooted Note 4 Verizon with CryanogenMod 13.0 installed and XPosed Installed.
Suggested Apps
Kernel Auditor [ROOT], will allow you to adjust kernel settings. Such as CPU clock speeds and thermal throttling, if your phone is too hot.
Note: About ROOT[/], you will have root once you finish this guide. But it is disabled by default, you can enable root in developer options (no reboot required when changing). Unlock your developer options again, and scroll down you will see an option to enable/disable root. This allows you to keep turn off during normal use, and only enable it when you need to install an app that requires root. You can always just leave it on all the time, that is your choice.
Note: Some apps on Google PlayStore will become unavailable due to incompatibility (according to google, HA). Such as YouTube Music, you will no longer be able to install it through the store. But you can install it by using an APK site, such as APK Downloader. On this site you find the app you want on play.google.com, copy the HTTP link and put it into the APK Downloader and it will generate a direct download link to the APK file. Copy onto your phone and sideload (ie. install) through file explorer. I don't endorse them, they are just one of many places you can get APK files.

Yea I do appreciate the help Bicknasty. I'll add you to contributors list later as helping with cyanogen issues I was having.

You know it wasn't so much that it annoyed me it's that there was no concrete guide telling me what to do. It's a thread here, a post there to do a specific thing but they aren't coordinated in a logical way for users to easily find.
Alright ignore what I said before this edit, I just skipped a step.
I must say though, steps 41-43 are very confusing. What is the ROM folder?

The ROM folder I'm referring too is the folder inside the Jasmine zip file. I only reference it so people wouldn't try to take just the files inside the folder which is inside the zip file. Lol yea that's confusing....I'll think about how to rewrite those and make adjustments in a couple hours to make it clearer.
But basically when you extract the Jasmine zip file it creates a folder with files in it. Copy the whole folder not just the files to where it makes your recovery folders.

Okay, awesome. Also I think the TWRP part could be explained a little clearer.
Other than that, 100%
oh also, at the start I would say to read the entire thing before starting, and give a warning that downloads will take like 4 hrs

Lol yea, didn't think to mention reading the whole thing first. To me that's a given I always read everything before starting. I'll add a note to read everything.
As to download time, well it is like what 12 gigs in total? Basically 4 full versions of the Android OS at 2 gigs reach plus all the extras.
I'll try to see if I can't explain the twrp recovery of Jasmine better. Only reason you need to do Jasmine is for the 6.0.1 device drivers (such as modem).

I've modified the guide appropriately, to resolve all of the issues (I think) you mentioned. And to make some steps easier to understand and follow.
I also added a recommended app on the bottom, and mentioned a site you can use to get PlayStore apps which will now list as incompatible with our phones.
Finally, question: Did you succeed using this Guide? Just curious if everything is working as expected after following my guide. I wrote the thing from memory, after spending 3 days rooting my phone and figuring everything out from various sources. Hopefully this saves people some time where they don't have to piece a dozen sources together to figure out how to do it. I only mentioned the main 4 I referenced, but there were other lessons learned from various places that aren't covered in those posts.

I was quite successful with the root. Even though I messed up a few times (skipping steps), it all works out and now it's working lovely. It only took an hour of actual work, plus a lot of download time because of slow hosts.
Thanks so much for the guide, the only issue was with the slow hosts, and that's hardly your fault. I do wonder if maybe setting up a torrent of the heavier files might help though.
Edit: I will say, this is a wonderfully tedious root effort.

An hour..........I spent 2 hours watching kingroot try and root my damb phone, LOL because I didn't wipe before trying to get temporary root the first time you use it (before I read in a post that wiping twice will make it MUCH more successful). Took me 10+ hours of actual work to get my phone rooted and CM 13.0 setup, because I didn't have steps to follow, LMAO. Made it up as I went.
As to the Torrent, I'd be the only one sharing and my upload speeds are not that great. maybe 500 kbps, I live in a rural area. At least my download speed is 40 mbps.
And it is hellofa tedious root for the Note 4, I haven't seen any other phone as crazy tedious to root.
Edit: Mind if I add a 'success story' section and add you to it?

Oh of course, go ahead and add me.
Also, if you do end up making a torrent, i'd be happy to help seed at least for a while. I have pretty good upload and no data caps or anything so it would probably help a bit (anything is faster than that 100 kbps that xda was giving)
You called N910VVRU2BPA1_N910VVZW2BPA1_VZW.zip, "N910VVRU2BPA1 Full Firmware". Which kinda got me confused, (maybe its just me trying to do this at 1 am >_>) but might want to edit that. Other then that Iv'e had a pretty easy time following this guide. Thanks! (still doing it fyi, I got an infinite bootloop, so figured I messed up somewhere after reflashing TWRP, now im starting from scratch.)
I have a Very weird problem , I followed your instructions correctly i was on step 25 did exactly what you said pulled the unpluged the USB and pulled the battery and and waited 5 seconds and put the battery back in and rebooted the phone only problem is now it is stuck in a boot loop of the image Samsung galaxy note 4 and just keeps rebooting . I haved tryed doing a factory reset and wiping cache and reinstalling 5.1..1 via odin and it is still doing the boot loop i am not sure what i did wrong or what to do . I know its not hard brick because i can get into recovery and download but just wont boot the past the Samsung not 4 logo

Was this after the first time you inputted the adb commands our second? Make sure you pull the SD card after the second time, as it will cause reboots after the second time until you reformat the SD card on your PC. Size will be wrong on PC but size will fix when you reformat the SD card a second time on your phone.
Edit it creates like 20 partitions on the ad card when you do adb, it creates a backup of your phone os.
