Nexus 6 soft brick help - Nexus 6 Q&A, Help & Troubleshooting

I flashed android m preview last night. i needed root so i flashed it and that flash failed, which seems to have corrupted the rom. Im hoping i can get my nexus back but im having some issues.
Recovery- i didnt flash twrp, its stock android m recovery
factory reset- all this does is erase and my rom still is corrupted
fastboot- computer reads it, i can see it in device manager as "android bootloader interface, however adb wont read. no devices in adb devices
ive uninstalled and reinstalled the google drivers several times to no avail. ive tried it on a different pc and same no dice.
ideas?

adb commands will not work in fastboot mode.
read this. it shall set you free

ingnore relock bootloader part!!

1. Boot into bootloader 2. fastboot flash system [system.img from preview 3 rom] 3. Wipe caches 4. Reboot

I admit i was trying to use adb to see if the phone was connected... bad habit i guess. The connect to adb in recovery option was not working at all. I blame this all on the MM bootloader. I have a bad taste in my mouth. In the end wugs saved me. I guess that day i needed the process simplified. Sorry for late response.
Anyway, phones fixed, this matter is complete. Both you folks are amazing. Im sending virtual hugs to all.

[Q] 1092 TWRP on 5.0 bootloop, stuck in recovery [SOLVED]

Hi,
I was on 5.0, running stock recovery and rooted. Today, installed TWRP for 5.0 on my device. I tried to flash the droid command center widget on my phone usng twrp, and it failed. I also hit the fix permissions option. After that the phone does not boot up, simply flashes the unlocked bootloader sign and shows the moto boot animation for a second or two before shutting down.
I can boot into recovery, and the computer detects the phone. But adb doesn't detect the device. I have the 1092 5.0 OTA on my computer and saved it on the phone in an attempt to flash it thru TWRP, but that failed with the message shown in the img attached. I also tried flashing stock 4.4.4, but that gave an error "Updating partition details" failed.
Can someone help me get back into my phone? :crying: ADB doesn't seem to be detecting my phone, else I'd have tried to install a rom via fastboot.
I have multi-tool v4.1 installed, would I be able to flash a rom (stock unrooted and full wipe is perfectly fine too) via that considering adb does not detect my phone, but the computer does?
Well, that looks annoying.
I've found myself in similar situations when I've accidentally flashed something I shouldn't have. The good news is that if you can boot to recovery you can also probably boot to the bootloader and use fastboot.
Have you tried wiping everything and going back to stock? It's time consuming but at least you'll end up with a working phone.
I had to do this when I put the wrong recovery on a phone and it mangled partitions. Device wouldn't boot.
There are instructions for the moto x here

Thanks for the reply! Color me silly, but would I be able to use fastboot given that when I run adb the 'adb devices' command does not show my phone?

Because fastboot mode can start on your device even before Android loads (and can even run when Android isn't installed at all), fastboot mode is useful for updating the firmware quickly, without having to use a recovery mode.
Adb relies on android booting and usb debugging being enabled and the computer being authorized for debugging (L feature). Fastboot does not. Try booting into the bootloader and then run "fastboot devices" . Mine shows up. I suspect yours will too. If it doesn't then I'm out of my depth here.

Ah yes. For some reason, my fastboot file had gotten deleted from the folder and so the command didn't run. Everything went smooth once I noticed that. Had to downgrade to 4.4.4., but w/e. Thanks @oldcynic

[Q]Stuck in boot after root attempt, even after factory reset. Help!

Hey guys, last night I tried to root my device (XT1058) following the guide [here](http://forum.xda-developers.com/moto-x/general/howto-root-moto-x-ver-4-4-4-xt1060-t3118342). Stupid me decided I wouldn't need to go back to stock ROM like it says in the first step. I continue with the guide, follow every step, until I reboot. After rebooting my Moto X gets stuck at the white screen with the blue circle M. I panicked, read a lot of things online, followed them, and nothing worked. I reset the cache partition in recovery mode when rebooting into fastboot, still nothing. I also noticed that my device is no longer detected in ADB at all, even in fastboot. So after just giving up, I read online in multiple places going to recovery mode, and wiping the whole phone/factory resetting would fix it. It still is not recognized by ADB or finishing booting. I realize I should've been more careful. Please help!
First thing... when the phone is in Fastboot AP menu, you can't use ADB. ADB wont work and wont see your phone unless the phone is fully booted. (i.e. adb.exe and fastboot.exe use two different modes on the phone).
Next, I've seen that symptom before, but I don't recall how to fix.
I would really consider asking in the thread for the process you were following.
If no one gives you any suggestion, you could always try re-flashing the stock image for your phone that matches the highest version you've had installed on your phone. (On fastboot screen you can see bootloader version, so match you stock version to that. see the list of known bootloader versions at -> http://forum.xda-developers.com/moto-x/general/info-warning-risks-downgrading-impacts-t3058202 ) And use mfastboot to flash it (follow option 5 in the 2nd post at -> http://forum.xda-developers.com/moto-x/general/faq-how-to-prepare-ota-update-carriers-t3126425 )
I'm pretty sure I saw this on reddit. You had a mac right?
You need fastboot installed on your mac:
http://forum.xda-developers.com/showthread.php?t=1917237
Assuming you have fastboot working on your mac and your phone this thread method two:
http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
Use fastboot instead of mfastboot for the sytem.img file.
If you receive an error with flashing system you could try:
Code:
fastboot -S 0 flash system system.img
If u can still enter recovery mode, factory data reset from it , if u can't boot still after resetting , u have to flash the full stock ROM.....

I simply cannot flash recovery

I nearly bricked my Razr i XT when downgrading from a Kitkat update to JB 4.1.2 but thanks to the great work here I am making some progress but cannot get Recovery or Root. the unlocking of bootloader via the Motorola website went fine and thanks to this post
http://forum.xda-developers.com/showthread.php?t=2239706 I got the rom I wanted, and it's fine.
I have read many other tutorials on installing a recovery and have downloaded and tried 6 or 7 CWM and TWRP images
but it never completes - fastboot says it has, but the phone stubbornly hangs at the flashing.
I have no problems getting into fastboot, but failed many times, and in desperation have tried with USB debugging on and off
and with and without sim and sdcard inserted.
attached are some photos to show where I am stuck at, and I would greatly appreciate some help

U said fastboot hangs at flashing the recovery, but on the command lines on your PC it says finished. Have u tried booting into recovery?
What recovery did u use and where did u get it?
USB debugging, simcard and sdcard don't have anything to do with fastboot. But it is likely that u didn't know that
thanks for looking at this.
I did try booting into recovery from my PC by after rebooting it and then taking the recovery option, but the phone hung at the Motorola bootloader unlocked warning screen.
this link was typical of the various tutorials I used: http://androidteen.com/motorola-razr-i-how-to-root-and-install-clockworkmod-cwm-recovery-on-android-4-1-2-jelly-bean-firmware/
to be fair I cannot recall where I got all the recovery images from - I have that many, and had to rename them recovery.img, so cannot remember the original download names
update:
I have just tried an app from the google play named Root Android, which advised trying other apps - Kingroot, Framaroot & Towelroot,
but they all failed .
what did catch my eye yesterday was the yellow text when in fastboot that says 'dismatched partition entry'
I ignored it as the img files I was trying to flash are all much smaller than the 100mb stated,
but today I am beginning to think that perhaps my recovery partition is corrupt and look for ways to repair it.
does that make any sense?

That could be it. Try flashing a rsd lite package from JB. Than go to the recovery and see if u have stock back.

thanks HazouPH, I'll give that a go
I have solved my problem with CWM:victory:
whilst I am not 100% certain I am pretty much sure it was a driver problem - for those who this may benefit, here is what I did.
1. I did not reflash my phone, but stayed with the one in my original post.
2. remember that the main problem was that Fastboot said I had succeeded in flashing a Recovery image, but that the phone 'hung'
at flash as in my photo. and then from my phone I could not get to recovery from the fastboot menu .
3. I stumbled across a posting (on XDA, but I cannot remember where) that said the Motorola drivers were not as good as they should be and that the Motohelper one's would be fine - so I downloaded them, and have attached the zip below.
4. I then decided to tidy up my PC and uninstalled all mobile phone drivers, plus any redundant USB Device drivers
5 for the USB tidying up I tend to use USBdview, which is superb and can be found here
6 when all this was done I simply tried the reflash of CWM - and got the same situation I had been having all along
but amazingly, when I selected 'recovery' it went in CWM - I nearly fainted with surprise!
from all this I can only assume it was a driver problem as I had changed nothing else.
perhaps it was Motohelper drivers- perhaps it was USBdview that did it for me - I will never really know, nor care!
I now have CWM v6.0.1.9 - it is touchscreen and permanent, plus I use the cute Reboot by app by Petrus to control my phone.
happy days!

Recovery Issue - Rom: Invictrix 8.1.0-1.0

I'm stuck at an issue that I've never seen before and need some assistance. I flashed invictrix 8.1.0 not to long ago and then installed an updated version of the rom through the rom's updater. It went through the automated flashing of the updated version and now I'm stuck in a recovery that seems to be stock, but it's not the stock version I am accustomed to seeing. I can not do anything in this recovery. I have used adb to do things before, but now adb and fastboot seem to get stuck at waiting for device errors or error:device not found even though adb devices and fastboot devices brings up the phone being connected. I now can no longer boot into the phone as I did a hard reset while my phone was operational.
Have you tried booting straight into fastboot mode by holding down Power+Vol Up until it reboots? And then see if you can use fastboot on your PC to flash TWRP again.
Also, all those error messages. Did you at some point reformat the cache partition as f2fs? It's supposed to be ext4..
I can boot into fastboot. The computer recognizes the phone through fastboot devices and adb devices. However, issuing a command through fastboot results in a waiting for device message. Maybe I need to find a more suitable adb. The one I’ve been using is the 15 second adb that only installs the google driver and the adb. I never formatted anything. I’m not sure what to do at this point.
I would use an unbrick guide and start from scratch.
Is there one you'd recommend ? I'm using this one :

Yes, I also used it in the past and everything was ok.

NEM-L21: Stucked with wrong version of boot.img, no more possibility of flashing

Hello everyone, it's my first time writing here, but I’ve tried everything, searched everywhere, and am desperate for help.
I screwed up big time while trying to flash a custom rom on my nem-l21, as I successfully did before with my xiaomi... So what I did:
I managed to unlock bootloader with dc unlocker. Then I got stucked flashing twrp with adb tools. Everything was looking to be fine, no error messages, “flashing successful”… But, I was never able to boot into flashed twrp. Always got stuck on “your phone has been unlocked blah blah. Your device is booting.” It never booted, not in twrp, nor in stock recovery. I tried different versions of twrp from different sources, always same result (flashing successful, booting into recovery not). Booting into the system was fine. And then I made that horrible mistake. Oh, how I wish I didn’t!!
I read on some website, that you are supposed to flash the twrp as boot.img, not as recovery.img. Seemed illogical and stupid to me, but in the end I tried it. Of course, this just bricked my phone, with no possibility to boot. After hours of googling, installing, trying and crying, I managed in the end to flash back stock boot.img. But at that time, I didn’t know my build number (b359), and I flashed boot.img b351. So now I have a phone which boots into the system b359 with boot.img b351, but with lot of errors.
- developer options, security options, display and factory reset option doesn’t work and just crashes. Therefore I am not able to flash the correct boot.img b359 or anything else at all from pc, no way to enable usb debugging and oem unlocking. Adb devices → nothing. I am able to use fastboot (fastboot devices sees the phone), but when try to flash something, I get error “command not allowed”. Also I can’t enable unknown sources installation, which bothers me a lot. And I can’t make factory reset to restore the crashing settings. Also I can’t change display timeout, and original 30 secs is super annoying.
- I am not able to uninstall even apps installed by me, always just restarts system UI and app stays.
What I tried so far:
- flashing correct boot.img from pc, not working because of dev options crashing
- go into recovery, but stock one is overwritten with unfunctioning twrp, always just get stuck on “your phone was unlocked blah blah… your device is booting now”, but it never does, have to hard reboot
- go into huawei erecovery, which is working, but when I try to resolve problem from there, always ends up with errors and crashes
- connect to pc and use HiSuite, system recovery tool here always says “no problem detected”
- updating to b361 through system update settings, always crashes on 5% and sends phone into “your phone was unlocked blah blah… your device is booting now” error
- downloading the proper b359 as and update.app file, put it in dload internal storage → same error during update, put it in dload sdcard → same error, no matter which way I use to start the update
- boot into twrp or stock recovery.img through fastboot without actually flashing it, anyway error “command not allowed”
- do factory reset or update through dial codes (i.e. *#*#123456#*#* …), nothing worked
My pc is windows 10, all drivers up to date. Using powershell as an admin. Am an idiot for not making backup of the phone before I started...
So, now I have more or less functioning phone, but I can’t uninstall any apps at all, can’t install from unknown sources, can’t do nothing from pc, can’t make any update, and lot of important settings keep crashing.
I can use the phone like this, but if somebody could think about some solution for this ****ed up situation I got myself into, I would be grateful to him/her for the rest of my life.
Sorry for a long post.
Thank you in advance and have a nice day
I think using Hisuit will help. Enter Fastboot and connect ur phone to ur computer and use system recovery toll
