Nexus 7 2013 model, bootloop after battery dead - Nexus 7 (2013) Q&A

Completely stock 4.4.4 unrooted
Had recently switched to ART a week earlier
Boneheaded move, let battery die, will not get past Google logo
I seem to be able to get into recovery with a few tries, have ADB, forget why I had it
Would it be better to flash stock or unlock, root, and throw a custom ROM on it?
Welp, might be dead, can't get ADB to recognize it, suggestions? And yes, battery is fully charged

Try wipe dalvik , cache, system in recovery and flash a custom rom
. If that doesn't help then you need to go back to stock. Have you tried in bootloader, doing the driver steps in Nexus Root Toolkit (Windows PC) ? I had a boot loop and fully using all the steps with the drivers and everything else, I went back to stock and rooted it using Towel Root and flashed latest twrp recovery using Rashr from google play Store (with towel root and rashr you don't need a PC to root and install a custom rom)

cant root phone

Hello,
I got a new note 2 today , I rooted it with cf-auto-root-tolte. the root installed and when i check it with a root checker it says rooted. So then i restart the phone like im going to install a custom os and it takes me to the factory os. How do i bypass this to install a custom rom?
If that's a custom rom it probably already has root, and anyway, the new rom can't inherit root. What you need to do is to flash a custom recovery which allows installing zip. Then flash the rom zip from the recovery.

[Q] I was able to root my SM-T310 but can't install any kernels or roms

I was able to root my device using these instructions
http://forum.xda-developers.com/showthread.php?t=2401901
I can confirm that it is rooted, TWR is loaded as the recovery and superSU is running as well as some root-only apps.
The problem is that no matter what or how I try, I cannot get a new kernel to install nor can I flash a ROM.
If I try to do either via Odin it completes without errors (either on the computer or tablet) but when the tablet is rebooted, no changes.
If I try to flash a rom from the recovery it just errors out and fails
I even tried using Odin to unroot and reset back to stock and that worked but when I re-rooted it again I was back to where I'm stuck!
Has anyone ever seen this before?

1), If you used the TWRP from that post, then you need to update to a newer recovery. TWRP for KK
2). Telling us that "it errors out" is pointless. You need to tell us exactly what error you are getting.
3). Attach the recovery.log from the failed attempt to flash a rom. Google can tell you how to get the log.
welp, I feel dumb - it was the wrong version of TWRP that was causing the problem all along

[Q] need help

i unlocked bootloader on my nexus 7 2013 and tried to root it following this guide http://nexus7root.com/new-nexus-7-root/how-to-root-new-nexus-7-2013/ im running android 5.0 on it so i used the supersu 2.30 like it said once it started to reboot it got stuck in boot animation ( 4 colored dots swirling) abd i tried wipeing everything i tried reformat i tried factory reset im at a loss please help i have twrp on it and can get into it ido not have usb debugging turned on yet the device registers in device manager as nexus 7 but wont show up in libraries ( i run win7) i have downloaded a stock rom of 5.0.1 for my device ive downloaded android sdkive flashed i just rewiped dalvik, cache, data, system, and factory reset then went to reboot the system it said no OS the only thing on it is twrp atm
Flash the 5.0.1 firmware in fastboot. Then try to boot into system. If successful, try to gain root.
If it is recognized in the bootloader, use the factory image from Google for 5.0.1. Once you've confirmed you can boot, put it back in bootloader and run Chainfire Auto Root.

Nexus 7 (2013) lost root on 5.0.2 flashing SuperSU don't help

My N7 has a unlocked boot loader, and I have been using CWM ever sense I got it. I have had several ROM's installed and always had root. When I received 5.0.2 I lost my root access, and now it is running extremely slow, do to a tons of games my son have installed. I can't control autostart without root, and yesterday, I tried flashing and rooting, I both tried with TWM and CWM, and I installed superSU from boot loader, without any errors. But still I don't have su binaries installed. Also when I install boot loader it only works doing installation.
Please advice what you try next

Download the latest recovery and do a wipe of cache and dalvik cahe. Grab the latest supersu.zip from chainfire's website and flash it in recovery and see how it is.

Caught in Recovery Bootloop

Recently I flashed through TWRP Resurrection Remix new 7.1.1 Nougat on my Tmobile Note3. Was working great. I had the newest twrp 3.0. I was looking at a custom ROM that said I would need CWM so I downloaded CWM from Google play and I ran it. I decided to back up through CWM and it rebooted my phone. My phone rebooted into recovery, and is stuck in recovery bootloop now. It keeps rebooting into recovery. I tried to fix by taking out battery for a long time but when I turn it on againit goes back to recovery in the loop. It can power into download mode. I don't know what to do in that mode though. Please help me. If I'm to use a computer to flash a different OS please include all links to find the downloads as well as the links for finding the usb drivers. Anyone know what I'm to do?

I find it odd that you would find a ROM that suggests CWM instead of TWRP, but the way I see it is you go back to Resurrection Remix or try to flash the new ROM you found with TWRP (2.8.7 is recommended)
You can download the .tar file for TWRP 2.8.7 here: https://dl.twrp.me/hlte/twrp-2.8.7.0-hlte-4.4.img.tar.html
For clearer instructions, you can visit this post: https://forum.xda-developers.com/showthread.php?t=2672393
These are instructions to flash back to stock, root and install TWRP 2.8.7
I suggest right after doing this, you flash the ROM you want, that will guarantee a "cleaner" installation of the ROM
Good luck!

Thank you for your help. I did all the clear instructions from the thread. I couldn't get the CF auto root to stick. Also couldn't find a surfboard for TWRP 2.8.7, they only have 2.8.0 on the TWRP site, or TWRP 3.0. Ultimately I've got my original factory stock lollipop back. I'm no longer rooted. I had rooted before through KingRoot. I tried again and it says that I'm out on a list for root for my phone. So my phone works again. I guess I should be happy with that.
If you want to root, you could try flashing cfautoroot with Odin.

I did try to flash CF auto root with Odin after I flashed back to the stock ROM. But it didn't work. It stayed stuck on the T mobile screen for a very long time. So I just gave up trying to root again and stayed with the stock ROM without root. Thanks. Maybe I'll try again and see if it'll work next time.
Flashing twrp with Odin and flashing supersu from twrp had always worked for me.

Will that root my device?
Yes. When I want root with stock recovery, I use cfautoroot. When I want a custom recovery and root, I flash twrp and supersu.

OK. Thanks. Also, which version of TWRP? I can't seem to find a download for 2.8.7.0, only for 2.8.0.0 and 3.0 on the official TWRP site. Also where can I find SuperSu? Do I flash SuperSU with TWRP once TWRP is on phone? I read somewhere that the best version for TWRP is 2.8.7.0, but I can't find it anywhere.
Twrp for T-Mobile note 3: https://dl.twrp.me/hltetmo/
Flash twrp using Odin. Olen Odin, do not check anything except f reset time. Flash twrp. When you see the word reset in the status window, remove USB cable from phone, remove battery, replace battery, use button combination to boot into recovery, connect to computer, copy supersu to phone memory, flash supersu from twrp.
