Hi all, I'm having problems with my Nexus 4.
I'm on CyanKang & (tried to, it said it had an error & aborted the installation) installed a nightly build which wasn't quite right - must've gotten garbled when downloading or something. Point is, my phone is stuck in a boot loop.
As it's only a 8GB one, I, somewhat stupidly, didn't keep any stable versions of the ROM I was using or backups on the device.
Now I've downloaded a stable version of the ROM but the problem is I have no way of getting the .zip onto the device. It doesn't mount on my computer & according to adb, it's unauthorised & doesn't bring up the authorisation dialogue to let me grant it authorisation. Killing & restarting adb server & unplugging & plugging in the phone again didn't make a difference.
I'm a bit lost as to what I can do to get my phone working again.
Thanks in advance.
Fixed my problem - cleared my personal data on the device which deleted the adb key. Then flashed a working boot.img with fastboot which let me authorise adb & push an update file to my phone which I could flash in recovery

Hello, brand new to the Kindle. I rooted my device just fine last night and decided to use Kindle Fire Utility to install TWRP. ADB was recognizing the device perfectly and the script seemed to be running fine until it rebooted the Kindle. At that point the script said "reboot: operation not permitted waiting for device" for an extended period of time. After waiting awhile, at this point I did something I probably shouldn't have, I unplugged the Kindle and rebooted it using the power button. It's been getting stuck at the "kindle fire" boot animation ever since. I haven't gotten a screen with a triangle and fire logo.
I tried following the instructions in the sticky but it seems adb no longer recognizes the device, so I can't push zergRush or anything past that.
Is it permanently bricked or is there a method to fix my problem yet?
Thanks for any help.
_______________________
Update: kindle was fixed by uninstalling drivers, reinstalling as android composite usb device, and switching it out of fastboot. not permanently bricked.
sounds like its in fast boot.
open the utility again, check if its in fast boot, if it is run the install command again. if u can't get it installed, use utility to change boot mode back to 4000.
I had the same problem this method worked for me http://forum.xda-developers.com/showpost.php?p=20509949&postcount=245 http://forum.xda-developers.com/showpost.php?p=20421225&postcount=222
Thanks for the fast replies!
When I try to change the bootmode using the fastboot it just says waiting for device and never progresses. KindleFireUtility shows ADB Online, Boot status at 4002, and fastboot as offline. Device manager doesn't show a Kindle, just an android adb interface with a yellow ! triangle.
I did restart the PC once and the kindle a few times. No luck yet.
I installed the ADB Composite driver again for the device and got this error (attached)
I had the same issue. It turned out that I had forgotten to update my computer with the drivers needed for TWRP install after copying them to the Android and .Android folders. I was able to get to the first reboot.. waiting for device and then checked device manager when it wouldn't progress. I found that the the driver was unrecognized. After updating the drivers in device manager, TWRP completed install successfully and I was able to backup my FW6.2 and then flash CM7.
uninstall the driverand use the driverin the utility thread? someone said leaving ur kindle connected to ur pc and rebooting ur pc will reboot the kindle? if it works su with terminal and change bootmode back to 4000
sent from my kindle fire
Alright everyone, I got it working after uninstalling the driver for the Android device, shutting down, starting up again, and plugging in and reinstalling the driver, then changing the bootmode using the instructions previously posted. Thank you all SO MUCH for helping as much as you could. Now to try this again!

Now I'm wondering what you mean by making sure the drivers are installed for TWRP to install correctly. Obviously I missed a step the first time, what do I do to make sure I don't miss it again? Right now when I try to install TWRP again it says "The system cannot find the filepath specified" several times.
would recomend to use following:

change bootmode, install twrp or whatever with the utility
Got twrp on it last night successfully and flashed CM7.
My question is somewhat related to this thread...
I'm on 6.2 (wifi turned off) and was already rooted and am trying to update to the 6.2.1 secured update with root installed update found on XDA. I'm using Kindle Fire Utility v.6, and to the best of my knowledge using the drivers included with the KF Utility program.
In the utility I show...
ADB Status: Online
Boot Status: 4000
Fastboot Status: Offline
Question is I'm not familiar with fastboot and unclear if I have everything configured in order to (safely) install TWRP. In a command prompt when I type 'fastboot devices' nothing is displayed ("adb devices" shows the device). Combined with the fact I've never seen anything but "Offline" for the Fastboot Status, I'm a little concerned I'm missing a piece of the puzzle and hesitant to install TWRP until I know better.
Any help/advice would be appreciated. Thanks!
look at my post on page 1 of this thread !
@Stevebro: I believe if you are using KF Utility v.6, then you should be good to go. As long as you installed and updated the usb Drivers and then ran zergRush, you should be at the point where you can install TWRP. Just make sure you are using the latest version of KF Utility and it should go pretty smoothly.
... After you install TWRP, I'd recommend going back to your KF OS and do a Titanium Backup of your apps and then doing a TWRP backup. When you flash to CM7 you can restore all your apps easily and painlessly using Titanium backup to restore with the Batch restore option.
Couple nervous moments, reboots and switching out of fastboot mode in the utility... but it all went well. Thanks for the help!!
glad to hear everything is fine ...
Glad to hear everything worked out. I myself sat staring at the "yellow triangle" for a couple of hours. lol, but I just kept working through it and tried not to panic and I got everything working again.
I think OP should edit the first post, or get a mod to edit the title. I keep reading random posts about "lot's of people permanently bricking their Kindle Fires" while I cannot recall a single instance of someone bricking and having to return one and it is getting tiresome.
I was running CM 10.1.3 with no issues. I was attempting to connect my Exchange E-mail account and it said that it needed to encrypt the files, not a big deal, I have had to do this in the past. It starts to do its thing but I see no progress bar like I am used to, just the CM logo spinning. I thought there was a problem and restarted the phone (big mistake) and now I am getting a message that there was an Encryption Error and it tells me to reboot the phone and then reformat. It reboots but goes right back to the message. I boot into recovery mode and attempt to load the .zip from SD card. I get an error "E: can't mound/sdcard". So I'm thinking I need to sideload instead. I download the SDK per some instructions on the internet, install the platform-tools and the USB drivers. I think everything is where it needs to be, I connect the phone, find the ADB.exe file, run a command prompt, type ADB devices but I get nothing.
Please let me know where to go from here!!!
Thanks in advance!
Bump for some ideas for this guy.
Resolved!
As the title says, I wanted to try CM installer, and I was on everything stock, not rooted. I downloaded PC, and android programs, followed the instructions, however at one point CM installer on my PC said it cannot communicate with my phone, and it was when it was trying to flash recovery. It said I should try different cable, or USB port, but no luck with either, and now it says my phone is not supported.
I tried to enter recovery, but I only get CM guy and it's stuck, even when I turn off the phone, it turns itself on automatically, and to fully turn it off I need to enter fastboot mode, and then turn off. I tried flashing full stock image (I know how to do that, and I have previous experience on this phone), but my fastboot crashes (Fastboot.exe Has stoped Working), tried to download fastboot again, but nothing helped. I also tried to flash recovery only, and I get the same thing... Also tried to do that with custom recovery, but nothing....
Is there something I can do, or do I need a new phone?
Also, I had like 70% battery when I started, so I am afraid to keep trying, cause if I go out of juice, it's game over, right?
Looks more like issues with your pc communicating with your device, which might have causes other side effects due to that. But I have not tried CM Installer yet.
You should see about getting fastboot working correctly first and getting the right adb/fastboot driver (such as latest Universal Naked Driver, link in my sig). You should also use the latest adb/fastboot .exe from Google, download their latest ADT package. If it still crash, use it on a different machine, if you're on Windows 8 try Windows 7 or Ubuntu.
Also make sure the factory image isn't corrupt, I always have issues downloading it from Google.

If the battery goes to 0%, just charge it, do you think everyone throw away their N4 when the battery goes to 0? There is the red light problem, but its an easy fix.
Thanks for answering, I fixed it with a strange method (to me). On CM forum j_cor told me this:
"Your device appears to be stuck in sideload. So the good news is no, you are not bricked. Here is what I would try to do:
1. Boot the device - wait for the "stuck" CM guy to display
2. Plug phone to PC and open a command prompt to the directory to C:\Users\enter_your_name\cminstaller\bundle\win32
3. from the prompt "C:\Users\enter_your_name\cminstaller\bundle\win32>" type "adb.exe sideload ClockwordMod.cer" (no quotes) and hit enter
4. This will try and sideload this .cer file and will fail - but it should kick you out to the main recovery screen. Select the Reboot option from Recovery
5. Device should boot back up. It will most likely still be the stock ROM. My guess would be that something disrupted the sideload process when installing the system.zip with CM."
However, this did not fix my problem, but it got my phone to communicate with fastboot. So I was able to flash custom recovery, and do a factory reset, which brought me to the stock ROM, I flashed CM the old-fashioned way then.....
And my PHONE IS UP AND WORKING AGAIN!!!
The main problem in communication was that phone blocked every time I booted into fastboot, and plugged USB cable in.... It immediately became unresponsive to any commands, after I did this, phone wasn't getting stuck in fastboot, so that solved my issue.
Hi folks,
So, after little usage due to instability caused by the Lollipop upgrade I hadn't used the TN7 in a while. Yesterday I thought I'd have a go at reconditioning it.
Background: The bootloader has been unlocked, recovery was TWRP, I'd flashed and reflashed stock ROMs of KitKat and Lollipop several times previously. The main problem in Lollipop was that whilst the SD card files were showing up fine in FS Explorer, I couldn't see any of my files or folders when looking at local storage. Also, Google Play Services refused to update (or install using an APK).
Yesterday I grabbed the factory ROM from the nVidia site to do a full factory install and reset. I followed the instructions, flashing the recovery, boot, system, userdata, staging blob and dtb in that order. I then rebooted and...nothing. No power (or so it appears), no boot screen, no ability to get back into the bootloader, nada, zilch. When I read back through the flash commands I noticed that the final part of flashing the system image failed, which could well be the cause - I should have paid more attention.
I've searched all over and tried multiple options to get the TN7 to boot or show some signs of life. I don't even get an LED showing when plugged into a wall socket to charge.
The device doesn't show in fastboot or adb on the Mac. I did however get a small sign of life from Windows. If I hold down the power button for around 10 secs and let go, I can hear the Windows chime of a device connecting, immediately followed by a disconnect sound, the Device Manager updates but shows nothing new.
So my question is: have I completely screwed the pooch, or is there something that can be done to resurrect it?
Cheers for reading,
Gray

Hi,
It can be fixed via apx mode.
Download drivers and switch to apx mode.
Follow instructions http://mobileviandroid.blogspot.in/2015/07/nvidia-tegra-note-7-apx-images.html?m=1
Remember to change your device serial number as mentioned in instructions.
I also faced the same problem as you are facing now. It fixed. If you need any help further just post. God bless. Hope it helps

Hello everyone,
I have a very peculiar problem with getting my Essential Phone to work again. It was lying around for roughly two years as I switched to another phone. Seeing as one of my relatives needs a new phone and has really low requirements I thought I could try to set it up again. I downloaded the official drivers again (Version 1.0.0 I think) as well as the last official release of fastboot images (February 2020).
Before I switched to a new Phone I had the Essential running with Lineage OS and remember wiping it with fastboot -w after I got the new device.
Now when I try to flash anything the device won't respond. It shows up when fastboot devices is used in the bootloader, but all fastboot commands get no answer whatsoever. I then switched from the official fastboot drivers to the latest android drivers which then gave me the sending x to y message when I try to flash anything, but nothing actually happens.
Interestingly enough, I can reboot to bootloader just fine and the Lineage Recovery is still accessible eventhough it shows an:
E: Failed to bind mount /mnt/staging/emulated/media/0 on storage/emulated: No such file or directory
on the bottom which leads me to believe that my device partitions may be corrupted outside of the recovery partition and the phone is bricked. In recovery adb commands can be used and I can reboot to bootloader for example.
When trying to sideload via the "Appy Update" function of the Lineage Recovery, I get an:
Error applying update: 26 (ErrorCode::kDownloadMetadataSignatureMismatch))
everytime. I tried different methods and Roms but nothing worked so far.
Can anyone help me with regards to bypassing signature verification entirely or point me in the direction of another solution?
Thanks for reading, I hope you have a nice day!

I've been reading around a little, it seems like it could be a recovery issue? try the official lineage recovery if you're not already. If you can get fastboot working at all try to reflash the stock rom and go from there.
I had a similar problem. Use a windows computer with the essential drivers (you can download from reddit) and use the official cable
DO NOT use the cable supplied with the Essential phone for data transfer, it is likely to brick your phone. Use a high quality one from a reputable manufacturer!
