S**t, you're going to download the factory image from here
https://developers.google.com/android/nexus/images. It's a .tar file. Use 7 zip to extract it. Once you extract it there's a .zip file in it. Extract that too. In there is a system.img. You're going to use that file in fastboot

Bricked Note 3 - Now I need help!

Hello, I followed the root guide in this forum, it was successful, then I tried to change the LCD density to 240 and the mobile refused to boot!!
I am downloading a firmware from sammobile.com but still have no idea how to do it! should I use Odin or Kies?
Switch off your Note 3.
Put it in Download Mode (Home Button + VolDown + Power), then press VolUp to confirm.
Plug USB cable to Note 3 and computer.
Start Odin, on the left, you'll see a yellow square with "Com.xx", that's confirm your Note 3 is recognized by Odin.
Extract the archive you dlded from Sammobile, Samfirmware... You must have now a .tar or .tar.md5 file
Put it in the PDA field of Odin
Press Start
Wait until reboot
:good:
why not just flash a pre rooted rom in the dev section. You already have cwm. Can you get to cwm?
Edit
or do what luminouche says. You'll probably have to root again though. Not a big deal.
Thanks everyone! It is back to life now, but I will probably try again with the Screen Density thing.. I cannot stand the 480dpi
I think its very hard to brick a galaxy phone.

But why such a big change. This isn't the note 2. You went to the dpi you would use for the note 2. Try 340 or 380 instead

mine is stuck on samsung logo after boot. I can still access the cwm recovery.
Anything I can do or I have to flash the rom again. And will I lose my data ?
How does it happened? have you flashed anything?
Any way you can reflash ROM, flashing stock ROM won't erase data.

I flashed a animation zip file in CWM which I found on xda. There is also a restore framework zip to undo what the animation file did. But I can not transfer that to my phone as its not showing up as a USB drive in my laptop.
Any solutions ? please be detailed as I am new to android.

Try this by using a fat32 micro sdcard.
1. Copy restore to the sd card
2. Insert sd card in phone
3. In CWM flash the restore.
if that doesn't work you will probably have to flash your firmware again.

I think better to have a look to script of estore zip,what restore file does do. bcoz if that packed with some files which is not from this device than it won't work. If previous file which he flashed have script to make backup and restore.zip have script to restore same thing then only it will work.

This is the thread from where I got that animation zip file.
And I rooted by following the steps in this thread http://forum.xda-developers.com/showthread.php?t=2460720
Yes I am from India. Delhi to be exact. I just don't want to lose data as I spent a lot of time customizing the phone.
Ok good news is that you can restore fom that zip, bad news is you need SD card, if you can manage that then it's easy.
otherwise
If you knoe adb, you can push file with to sdcard with adb command.
OR
simply flash stock ROM, that won't erase your data but you need to reroot.
Do you have internet access on PC?

Okay I got my phone working. I used adb pusher app , found it on xda. Simple to use.
But now my wifi is not working. Its stuck on turning on.
I did a little searching , the issue was solved by flashing a custom kernel.
Can I do that on a stock rom like mine. And which kernel will work with note 3?
There is no custom kernel available in my knowledge on your device.
Make backup and try wiping device otherwise flash stock rom.
And don't flash any other device component on your, you may soft brick your device.

[Q] Android 4.4 OTA fails on Status 7 system bin debuggerd

I am currently running Nexus 7 (2012) Wifi Android 4.3 Build JWR66Y rooted with CWM and stick mount but when I try to update Android 4.4 OTA it fails on status 7 system bin debuggered. As I was able to just run the Android 4.3 OTA when I upgraded from Android 4.2.2 without any problems this Android 4.4 update is certainly very frustrating. Since I am still a newbie at this could you please provide a step by step of how to get this to work using NRT? Do you have to unroot before installing the update and then reinstall all your apps after? Any help would be greatly appreciated.
Thanks,
KodachromeBob
I'm in the same boat. Trying not to have to start from scratch so I really prefer to run the update instead of flashing the entire device. Vague recollection was that debuggerd gets replaced by stickmount but I tried reverting to the backup file that I had and it still gave me the same (Status 7) error.
I think we just have to find the correct version of debuggerd and overwrite it, then sideload. Let me know if you make any progress.
If I remember correctly you have to be completely stock. If you changed anything the update will not work.

It's only aborting on that one file as far as I can tell. Would love to get an original copy and just overwrite the one that's on my Nexus 7 to try if it would work.
Is there a way to get back to stock but not lose all the installed apps and data? I don't mind not using the update file, I just do not want to go through the hassle of setting everything back up (reloading apps, wifi, etc.) again.

No, I just recall having to change the debuggerd file to get stickmount to work. I don't remember the details exactly (it was a long time ago) but I'm pretty sure that is all it was.

No worries. I just found another post (sucks that search is down) that says that if we just flash the boot, system, and bootload img files from KK that it should update without deleting programs or data... I think I'll give that a try.

Apparently I flashed in the incorrect order and just flashed boot and system. Nexus 7 appears to have booted up and my apps/data are still present. About screen shows
Android: 4.4
Kernel version: 3.1.10-gee1a0b2

Do I still need to flash bootloader?

The method of flashing boot, bootloader, and system img seems to have worked. Might want to give that a shot if no one uploads the proper debuggerd file. Best of luck!

Yes, just download the 4.4 image from google here:
https://dl.google.com/dl/android/aosp/nakasi-krt16s-factory-da7dee49.tgz
Unzip it until you can pull out the 3 image files I mentioned above. Then use NRT to Flash the files one at a time. You should be good to go. (fingers crossed)
Yesterday my nexus downloaded the update and asked me to press 'ok' to shut down tablet and install.
Just like after every system update the following happend:
Nexus turns off
... thats it, it simply turns off and nothing happens! Device is 2 weeks old now and i am thinking of returning it.
I'm on 4.3 and system tells me that there is no update available...
Nexus 7 2013 sucks!

Yes, you have to unzip the .tgz file, then unzip the .tar file to get the folder with the image files. 7zip works great. If you are on the stock rom/kernel rooted with a custom recovery (CWM or TWRP) you can fastboot flash on both the system.img and boot.img. Those are the only ones you need. It doesn't look for file verifications in system, it just puts the latest system image there. Flash the latest supersu in custom recovery and you get back root.
Successfully Updated to KRT16S
Could not have done it without the help of Wayno-san. I flashed Boot, Boot Loader and System images with NRT and voila a successful update to KRT16S. I had to ROOT again and reinstall Busy Box but that was not a problem. Thanks again Wayno--san for all your support.

You're welcome Sir!
Can anyone send me the JWR66Y debuggerd?
I'm also stuck trying to update to 4.4 and I'm hoping to avoid reflashing back to the stock /system. I've reverted all of the system files I touched so it's only debuggerd that's holding up the update. Thanks!

I also had to update manually because of Status 7 update in CWM during OTA flash. Slight inconvenience yes, but nothing major as I didn't flash "Data" via Fastboot command. Had all my apps retained in the next boot
Missing ART though. I don't really want to flash a custom ROM for it.
Anyone willing to send me the KRT16S debuggerd?
If no one has the JWR66Y version, I can just edit the install script to not check (and not patch) debuggerd, then load the KRT16S debuggerd after the update completes. Thanks!

did you uninstall exposed and any other mods?
I do not think uninstallation matters because flashing the factory image erases everything in system partition.
I did the very same thing to my Nexus 5 and nothing was wrong.
Apparently nexus 5 went through some processing in recovery after flashing. Nexus 7 did not, it just went straight into system after flashing and got stuck.
cool but how did you flash ? there's no flash-all.bat script in the archive ...

Hello,
I've flashed and waited 10 minutes ... then everything ok.

bye
how did you do to flash it ? I can't find the flash-all.bat file in the archive ...
Did you get the right file? Uncompressed with 7zip (I've used linux, but that's not a problem).
My steps:
- downladed file
- checked md5sum
- uncompressed
- adb reboot bootloader
- flash-all.sh (flash-all.bat in windows)
- waited
- waited
- waited
- et voila.
Now I'm flashing twrp and supersu.

sure, I've downloaded the file named razorg-lrx22g-factory-2ce5202c
it's a .tar and Inside there is only one file name razorg-lrx22g-factory-2ce5202c without extension ...
and no flash-all.bat file ...
Oh, windows.
With 7zip uncompress that tar too.
thank you,
*solved*
weird, the flash seems ok but it take ages to boot (the first boot after flashing) is it normal ?
up : It was
Use Windowns not MAC!!
Got bootloop using mac, though no prompt of error. besides bootloop, also missing partition table after flashing, so can't install recovery, or use fastboot erase, or any writing operation.
Everything's working when flashed on Windows!!!

Flashing SuperSU 2.45 through TWRP works fine.
What are we going to do about SMS and tethering though?

Got stuck trying to root, just want to return to stock/factory settings.

I'm new so please forgive me and my ignorance through all of this. I had a great root experience with my old LG G3, so when I got my Axon 7 (A2017U) I thought I'd try to root it too. I tried to follow DrakenFX's guide (http://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204) but I bit off more than I could chew. I got to the point where I had TWRP up, but this is where I think things started to fall apart. I was confused by the instructions and in a haste I continued anyway. In TWRP I went to Wipe>Format Data typed in yes like TWRP said and boom, I had no idea what happened. Rebooting only got a screen that said "Type in your password" but my passcode I had on the phone before it bricked didn't work. So by now I start panicking a bit. I thought I made a mistake earlier so I went back and tried to reinstall TWRP by putting the phone into EDL. The phone got stuck that way for a while, but I now I have it in TWRP. Right now, I just want to get back to safe stock android.
I'm 200% sure I messed with something I wasn't supposed to and I believe that is the system image(?)which Draken also linked (http://forum.xda-developers.com/showpost.php?p=68248798&postcount=53). I'm downloading it as I type. I'm going to do my best to leave my phone just like it is right now, in TWRP, and wait for more advice on this before I do anything else.. What I'm curious about is where did I go wrong and what do I need to do to get my phone working again, preferably without returning it? Thank you for any advice you have to offer.
Update: It's worth noting I didn't know to enable OEM Unlocking when I was in stock android. Dumb move I know. I'm new here.

Get DrakenFX b29 mergeboot stack and b29 stock system and flash it then u should be OK. I did this too.

I tried, but the downloads take extremely long and are unreliable for me. I was downloading the stock system file at around 14 kbps and it eventually failed. Any other suggestions?
Wipe cache dalvik data and system reboot, ignore error message and reboot

I've done the wipes multiple times. It's mostly the downloads I'm having trouble with. How and where do you get them? The links I found were dead or had a slow speed.

Did you save the recovery backup? If you did then use the axon7root.exe to flash the stock recovery. Then download the stock B20 from ZTE.

I've been able to find some recovery images that I found on other threads. The thing is, when I try to flash them on TWRP, I get an error about "/dev/block/sde14" being read-only.

no no no no ..................... put phone in EDL mode. Copy the stock image into the folder with the axon7root.exe file you used to flash TWRP. Make sure the stock file is named recovery.img (or whatever the TWRP file is named in that folder, it has been a long time since I did this). Then use the axon7root.exe program the exact same way you did before. It will flash the stock recovery. Then in stock recovery you can flash the B20 from ZTE

Ok, I will try this.
Update: I got the stock recovery back, but now I'm lost as to how to flash the stock b20 from zte. Thank you for all your help so far though.

Yes, I'm in the process of getting the update from sdcard feature working.
Update: Trying to use the update.zip file or unpacking it into the sdcard hasn't worked. Trying to use adb sideload returns "Cannot read 'update.zip'"

ok - download it from zte. Put it on your SD card. In recovery select update from SD card. Be warned it will work but it is slow. Also note that while I will not say the bootloader unlock doesn't work on B29, I can say it worked flawlessly on B20. If you want unlocked I recommend doing so on B20.

I tried that. It won't accept the zip file and it's unclear which file to sideload. Would you happen to know? This is what files are in the unpacked zip. https://gyazo.com/c7546c3ed0dcb0972653eaeba42fcb40

Maybe - I'd have to download it to find out. If you can't get stock recovery to take it this post http://forum.xda-developers.com/showpost.php?p=69434328&postcount=17 gives you instructions on what lines to remove from the updater-script to make it flash in TWRP (I didn't have a problem making the stock B20 go in stock recovery, but I was unlocked at the time). You could reflash TWRP and try that.
Or just try this in TWRP http://forum.xda-developers.com/showpost.php?p=68873482&postcount=2

I'm going to try the first option. The second option's link take horrendously long to download.
Update: Trying to flash from TWRP results in error "Could not find 'META-INF/com/google/android/update-binary' which makes no sense since update binary is exactly where it should be.
Further Update: It seems that the problem might have been that when I compressed "update.zip" to fix "updater-script" it changed to file path by adding the title of the folder "update" to the beginning. I think that messed with the path giving the the meta-inf error.

OK. How did you do that?

Just suck it up and download the 2 b29 files. If it is that slow pick a different mirror
