Stuck in a bootloop. Here's my story.
Updated to 4.4.2 earlier today.
Tried to root my Nexus 7 later after the update. Here's what I did:
rebooted into bootloader with adb (adb reboot-bootloader)
unlocked the bootloader with fastboot (fastboot oem unlock)
flashed clockworkmod using fastboot (this is the file i downloaded and flashed: -http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.4.3-flo.img)
rebooted into recovery
selected "install zip>choose zip from sdcard" (trying to install supersu.zip file that I had loaded onto the internal memory)
Here's where I ran into trouble. After selecting "choose zip" nothing happens, and a message shows up on botton of the screen that says "E: Can't mount /sdcard"
So I can't install anything from clockworkmod.
I rebooted into bootloader, tried to re-flash using fastboot - "device not found"
I tried to reboot the device into android - bootloop animation
I tried wiping data, cache, factory reset, dalvik chache, etc from recovery - still getting bootloop animation
Any ideas?
Ok, I wiped/deleted sdcard data from clockworkmod and I managed to get it to boot.
That's deadly but I still don't have root, which was the point of this in the first place. Anyone know where I went wrong?
Strange. I did pretty much the exact same procedure and it worked for me.
Sent from my Nexus 10 using xda app-developers app
So, I flashed TWRP.
Tried installing SuperSu from there. This worked slightly better than Clockworkmod Recovery, it at least could read the internal storage, and allowed me to select the supersu.zip file. But I get the following error when I try to install it:
E: Unable to open zip file
Error flashing zip 'sdcard/Download/UPDATE-SuperSU-v1.80.zip
Not sure what's happening here.... May have to do with the 4.4.2 update? Maybe I'll try flashing the 4.4.2 factory image and then retrying the above steps.
I also did pretty much the same. I had a new Nexus 7 2013. The very first thing I did was to update to 4.4.2 through OTA before I went to rooting procedures:
Unlock bootloader (data was wiped because of it)
Flash TWRP
Flash superuser.zip file through TWRP
Everything worked fine.

So I grabbed the OTA ZIP file that was posted here - THANK YOU by the way.
I boot into recovery and I am presented with the following :
Android System Recovery (2e)
the usual 4 menu options for Reboot, Apply sdcard:Update.zip, Wipe data and wipe cache.
I get an error on the recovery screen that says :
E: Can't open /cache/recovery/command
Can i still run the update? This is a relatively stock Incredible (Rooted, S-Off then unrooted.
Thx

I got that same error, pretty sure it just has to do with the 4 recovery commands your seeing right now. It probably just recreates that file once you see the commands. I went ahead and flashed the update.zip. I got other errors as it was flashing, but I don't they're linked.
Okay, so I'm trying to root my boss' phone: I did warn him that things could go awry but we went ahead and tried anyway. I'm using adb commands from a mac. I downloaded CWM toro (for gnex) and the lastest su.zip file. I unlocked the bootloader, flashed CWM, and was able to push su.zip over to the /sdcard through the command line (it reads 3985 KB/s and how long it took, etc.) - Now still in CWM, I can't seem to access the sdcard. I'm getting a "Couldn't open diretory." which shows up twice, followed by a "no files found" error. But the terminal window shows that the file was pushed over. Rebooting goes into a loop halfway through the splashscreen. Still have access to CWM and able to enter fastboot mode through holding VOL UP and VOL DOWN while powering. Any help would be appreciated!
EDIT: Tried Wiping Cache, reboot to recovery - still no luck. Tried Wiping Dalvik Cache, reboot to recovery - still no luck.
EDIT: Tried downloading appropriate recovery images from Google's website. Flashed files in order from http://forum.xda-developers.com/showthread.php?p=20441992 <--these instructions, everything checked out okay and still looping at boot.
I hope this is reversible. Seriously, anyone? Any help is appreciated.
Didn't think it would go like this as I rooted my GNex with ease (GSM version) using the same method.
Reflash cwm
+1 for reflashing CWM
Your FIRED!
So i had 4.0.1 rooted before. I decided to return to stock by flashing full 4.0.1 on TWRP. That's when I started getting the error. I flashed 3.2.8 on stock recovery 2.0 and dm-verity error is gone. But installing 4.0.1 on stock recovery 2.0 results to dm-verity error again. I cannot use adb sideload as my computer is too slow
More details: before, I successfully updated my OP3 with 3.2.8 to 4.0.1 without the dm-verity warning. After that, I flashed blu_spark's TWRP v11, swiped to allow modifications and rooted it with SuperSU 2.79 and flashed some mods, still no warning. Yesterday, I decided to return to full stock. I updated my TWRP to the unofficial 3.0.3-0 (the official one wasn't available yesterday yet), wiped system, cache, and data excluding internal storage, then flashed 4.0.1. The dm-verity warning started to show. I followed your guide and other guides here on XDA, I cannot fix it. The only solution I found is to rollback to 3.2.8, I installed the zip file on the stock recovery from your guide (flashing the recovery before). I'm having problems with adb sideload, PC lags so much and sideloading never finishes, so what I do is copy the zip file in the internal storage. After I flashed 3.2.8 and rebooted, the recovery was replaced by the V1.0 version that doesn't have the function of installing zip from internal storage, so I flashed your stock recovery again. Booting to the new recovery, I flashed the 4.0.1 zip and the dm-verity warning shows again.
Right now, my OP3 is on 3.2.8 with stock ROM, kernel, and recovery. No dm-verity warning. I don't know how to update to 4.0.1 without getting that again
Simple. New bootloader added that warning and the old one never had a dm-verity nag screen. Flash it and ignore it. It shows up due to TWRP installed.
Check the freedomos thread and download the 3.2.7 fw and flash with TWRP and its gone, I am not using the nougat fw on 4.0.2, always make nandroid backups
install beta 7 firmware
Don't bother! It's not worth it! It's just a stupid message!
I have tried by following these steps (I initially had twrp-3.0.2-1.28-oneplus3 installed):
1. booted to TWRP recovery;
2. copied recovery_OBT8N.img to phone;
3. installed stock recovery_OBT8N.img via TWRP as image > recovery;
4. booted to stock recovery (directly from TWRP);
5. while in stock recovery, I have wiped the phone (for a clean flash);
6. installed OxygenOS 4.0 (N) via ADB;
7. once the installation got completed, I rebooted the phone;
8. once the phone started, I did not finished the startup setting;
9. switched-off the phone and booted in fastboot mode;
10. flashed TWRP recovery - twrp-3.0.2-1.28-oneplus3 again;
11. switched off the phone;
12. started the phone in TWRP recovery; TWRP asks for a password to decrypt - ignore it;
13. wiped the phone (I wanted to do so to make sure it is a really clean install, even if this wipes everything);
14. rebooted again to TWRP recovery; this time I did not get any password prompt;
15. from TWRP, I copied SR1-SuperSU-v2.79-SR1-20161221223537.zip to phone storage (while connected to my laptop, obviously);
16. installed SR1-SuperSU-v2.79-SR1-20161221223537.zip, wiped data & cache and rebooted system;
17. everything went fine, with no dm-verity and rooted.
It will Keep showing Because You flashed Oxygen OS from TWRP . Try flashing this just after flashing the OS .
it will disable DM verity and disable force encryption .

Please try this method. Tested and it works for me.
step
Assuming your bootloader is unlocked. Copy
1. fastboot boot twrp twrp-3.0.2-1.28-oneplus3.img
2. Now you will be in TWRP, perform wipe -> Format Data, perform Wipe -> Advanced wipe "All folder" except USB-OTG
3. Reboot to recovery
4. adb sideload OnePlus3Oxygen_16_OTA_037_all_1701041839_401.zip (if adb cannot read, because filesize too big. Use laa_2_0_4.zip to fix the adb.exe first.)
5. After adb sideload done, reboot to TWRP immediately, enable MTP to copy the file: no-verity-opt-encrypt-5.1.zip into your internal storage and install no-verity-opt-encrypt-5.1.zip immediately.
Then everything will be fine.

I was not having any Issue . But Surely Your Help and concern is much appreciated
and Yes this is also one of the way to remove DM verity and use the zip
Currently using:
ROM - FreedomOS-2.1
TWRP - blu_spark_v11-oo3
Phone - Encrypted
I have the DM-Verity message at boot. Would reflashing FreedomOS-2.1 Through TWRP & then immediately flash no-verity-opt-encrypt.zip get rid of the message?
Thanks
Hey guys,
I was googling for the past few days who else might experience such problem, but I haven't stumbled upon such case. The problem is, I'm stuck on the bootloader part.
The initial goal was to root the device, so:
- I unlocked the bootloader,
- installed clockwork-touch-6.0.4.7
- wiped everything
- when I try to install SuperSU & new ROM I'm getting errors like
Code:
Can't mount /cache/recovery
Can't open /dev/block/platform/msm_sdcc.1/by-name/misc (No such file or directory)
Can't mount /cache/recovery/log
and a few other errors in this fashion about cache.
When I actually run the
Code:
abd sideload aicp_flo_n-12.0-UNOFFICIAL-20161020.zip
the installation tries to mount folders like /data but gets an error.
Finally it says
Code:
E1001: Failed to update system image
Installation aborted
Is there a way to re-format everything to FAT using fastboot and then begin everything from scratch? I have a feeling this is filesystem problem that it can't read properly or something... Maybe I'm wrong? What would be your suggestions?
Thanks!
I had a similar issue on mine a few days ago. I was completely stock and wanted to unlock bootloader, flash a custom recovery and then finally a custom ROM. I was successfully able to unlock the bootloader and flash the recovery (latest TWRP). But, when I tried to boot into recovery, it went past the recovery logo and then showed me errors like yours inside the recovery and rebooted. It then automatically booted into the recovery, showed the same errors and rebooted again. I wasn't able to do anything apart from booting into bootloader by sending an adb command.
Now coming to the part which fixed my errors. What I did was used the "fastboot -w" command (without the quotes) while I was in bootloader to wipe everything and after that, flashed the recovery again. Then I was able to successfully boot into recovery and everything has been fine since then.
I upgraded a couple months ago from 8.1 to 10. I ended up doing a full wipe ( or so I thought) through TWRP and flashing the 10 image. However, it seems that I somehow screwed up the encryption on my phone. I can boot the phone and put in my PIN to access and use the phone normally, but inputting the same 6 digit and my old pre-10 4 digit PIN into TWRP does not decrypt the phone and allow me to flash things. If I continue in read only mode in TWRP, I can flash but everything in my data partition has jumbled file names.
So my question is: Am I going to need to back everything up and wipe in order to fix this? Can I simply use Magisk to disable Force Encryption then decryp that way while keeping my data intact?
I would prefer using the simplest least painful way possible, but if I have to wipe to fix it then so be it.
Twrp decoding doesn't work for Q .. best to remove lock before entering TWRP
Also try "default_password".
Well I got impatient and ended up screwing up everthing.
Now I'm having trouble getting TWRP installed back on the phone. I have wiped everything, flashed the latest January factory image, booted to TWRP image, but when I attempt to flash the TWRP zip I get "failed to mount /system" and "failed to mount /vendor". If I boot back into the installed TWRP, I am not able to flash any other zips such as Magisk.

Disable your screen lock. Download twrp again to your pc. Put a copy of the twrp.img file on your phone as well. Fastboot into twrp, select instal, select image, go to your twrp.img,.select to install it to Recovery Ramdisk. You'll have to flash custom kernel and magisk again if applicable :good:
