[Q] Restore recovery mode - Nexus 5 Q&A, Help & Troubleshooting

Hello,
Can someone please help me to go back to stock recovery WITHOUT factory reset?
I've installed CF-Auto-Root v1.0 and then flashed to lollipop 5.0.1.
Now, whenever I try to enter bootloader from the Fastboot Mode menu (by the Recovery Mode option)
It doesn't do anything.
Thanks ahead,

You seem to be a little confused.
"Whenever I try to enter bootloader from the fastboot mode menu by the recovery mode option..."
First of all. The screen that let's you cycle through recovery mode, start, power off & bootloader (what you call fastboot mode) is actually the bootloader itself.
When you're on that screen that allows you to select the different option you are already in the bootloader so selecting bootloader will just take you back to that screen over and over and over.
If you want to go to recovery, you hit recovery. You'll see an android with a red exclamation mark that says "No command" or something to that effect. I forget exactly what it says off the top of my head. From there, you hold the power button and press volume up and release and it will take you to stock recovery.
Also, performing a factory reset will not magically install stock recovery for you.
I'd highly advise you to stop using any kind of toolkits or "auto" anything until you are comfortable doing it manually by yourself.
I recommend reading the entire roll up sticky guide by rootSU in the general section to learn what you're doing.
Here it is;

Read the entire thread. Read every thread linked in that thread as well. All of them. Otherwise your time on XDA is going to be very frustrating while you try to figure out how to recover from a bootloop or a wiped OS when if you knew what you were doing, would have never happened. Crawl. Walk. Then run. Baby steps. Start from the bottom and work your way up. Learn the basics before doing other things. Best of luck.

Thanks! How would you recommend to root my device? I don't want a custom recovery.

Read, read and then read some more. Rooting and custom recoveries are not tied together.

All the questions you have are covered in-depth within the guide I linked you to. You can boot into custom recovery without installing it with fastboot boot recovery instead of fastboot flash recovery. Root from there.

[Q] [q] cant enter CWM recovery ??

firsth of all hi to everyone, im new here , so be patient.
i was searching on the forum and try to solve my problem, but no succes.
all the methods ive tried are a no go

but have you installed CWM recovery?
User RecoveryInstaller to install CWM.
http://forum.xda-developers.com/showthread.php?t=1346180
/agree with @baseballfanz
Check that you have CWM installed. Then you should hold volume down + power button till you see in the screen something like (push vol+ to enter recovery). It will appear on the top of the screen. You have to wait a little since it first appears the ASUS screen and if you stop pushing the buttons at that time, the TF starts normally. You have to hold them a little longer till the text appears in the screen.

If they don't have CWM installed, that will only reboot the TF, not get them to recovery.

This is 100%. We've already told you this, in this thread This Thread.
You need to install a recovery image access recovery.
If you are this unsure of what you are doing i HIGHLY suggest stepping back and reading all about SU access and the rooting procedures again.
The "flash a new ROM to ________ device" steps are pretty much the same for every Android device w/o a locked bootloader.
Root
make sure SU access can be obtained
flash a custom recovery image
reboot into recovery
do a nandroid back up
wipe
flash
reboot
If you cannot get to where you want. You are doing something wrong. millions of people have followed these same step on millions of devices w/o any problems.

In essence there is nothing wrong with asking for help. Heck even the smartest of android hackers started somewhere, asking questions the selves.
The problem lays in the fact that is is pretty common knowledge and a simple search would of gave you the answers you wanted.
Keep in mind nothing i say is meant to come across rude. Sharp maybe, rude? no. If you take what i say as rude. I'm sorry.
No problem. I have been trying very hard to learn on my own. The problem I had with this was trying to find information specific to the transformer. I have done quite a bit with my other android devices and the transformer is new to me and since I use it at work every day I am probably a bit more cautious about it. Thanks, I am working on it.

help- bricked it, no recovery, what now?

Hey yall. I had the phone for 6 days before I bricked it. I am wondering if there is any stock recovery mode or anything or what I shsould do? I think something went wrong due to using the root toolbox pro app. I have done some backups within the ap as well as Titanium Backup but now the phone will not boot up and I dont know if/how to put it in factory recovery mode. Soft reset does nothing. The Motorola logo will show on startup but then the screen just blacks out forever, not off, just colored black.
A few details, the phone was rooted with Motofail2go, with no recovery and bootloader still locked as far as I know.
Should I take it to Sprint for a factory reset? Is this even an option? What are my other options?
Next time I will probably use the Moto unlock key so I can open the bootloader all legit like and have a recovery mode...
Try holding power button and the down volume key to power off. Once you power off press and hold them again. This should boot you into fastboot, Motorola's adb shell basically. This can take a couple tries, make sure the phone is powered down completely before hitting volume down and power button to get into fastboot. If you can boot into fastboot you can unlock using this guide: http://www.droid-life.com/2012/08/20/how-to-unlock-the-motorola-photon-q-bootloader/
Once unlocked flash the custom recovery of your choice (I like twrp). You can boot into custom recovery by holding volume up and the power button from a powered down state. Here is the link for instructions on how to flash twrp:
http://forum.xda-developers.com/showthread.php?t=1887070
Then you can download one of the stock backups for the Q posted in the development section and restore them using the custom recovery. Most of the ones I have seen have been compatible with twrp.
The only way to download the stock rom backups is to remove the sd card from your phone, plug your sd card into a PC or other device with a card reader, download the stock backups, and place the stock backup rom files on your sd card. Finally place the sd card with the stock backup downloads into your phone.
These backups and information on how to go through this process can be found in this thread on page 2: http://forum.xda-developers.com/showthread.php?t=2001226
The key is to make a backup of your existing rom with twrp and then move the stock backups from your sd card to the twrp/backups/yourdeiceserial/ directory. That creates a backup directory which twrp knows to look for backups in.
Don't feel bad, I've been in that state several times since getting the Q, live and learn.

If that does not work you could drop it in water or something. You have not officially unlocked boot loader so you still have warranty. Or you could just tell sprint it quit working and act completely clueless. At least its bricked with warranty still intact.

Both of the methods above are very effective. When I had the first photon I bricked it and just dropped it in water and did a claim. Depending on the insurance you have that way may cost you $100. The other method should work. When I first got this phone I did the exact same thing and to go back and unlock then flash twrp and in stall a stock backup someone had posted.

Thanks for the response. Is there anything extra extra special about getting into factory fastboot mode? I can't seem to get it done. Is there an official set of instructions anywhere? Does the phone need to be plugged into the PC? It was always my understanding (for the last week) that Power and Vol Down was the soft reset mode which reboots the phone. Therefore it always tries to reboot in normal mode. This is what keeps happening. It never powers completely down using this method.
Anyhow, once I follow your instructions, the Moto logo appears, no Sprint logo appears, the phone "powers on" but the screen is blacked out (not off). After waiting for a while at the blank/black screen, or holding down several buttons like vol or camera I get the first attachment: "Process system is not responding. Would you like to close it?" When I wait nothing happens. When I push OK nothing happens. By chance, I held down power during the notification and the power menu came up behind the ANR notice (second/third attachments). So obviously there are some things working but the main system isn't booting up. And either factory fastboot is nuked or I can't figure it out. When I power down from this accessible power menu and try to do the fastboot (Power / Vol Down) I still havent gotten it to work.
Any other ideas before I take drastic measures?
Since I bought it from Amazon would that be my best route for return or should I go thru a Sprint store?
Thanks in advance.
Hi again yall. You know once I got to thinking about it, I decided to check out the return policy on Amazon Wireless. They will accept any device under warranty for the first 30 days and it is up to Moto for the next 11 months of warranty coverage. They email me a packing label and it ships out 1 day and they ship out the new phone 1 day shipping. Hard to beat, just takes 2 days of shipping and some more fun times with my Epic, 10.1CM style, in the meantime.
Who's to say it wasnt some sort of hardware or software glitch that bricked the phone rather than my screwing around? Nobody knows and it isn't up to the consumer to prove his innocence. I bought everything legally, all the apps at the app store, and only ran the motofail2go root method. Wasn't running any custom Roms, Mods, or anything. I don't feel bad after they got me for another 2 grand for 24 months, and since I have been with Sprint for 10 years;l I have spent well over 10k or 15k with them lifetime.
If any other method pops up between now and when I ship it out I may give it a shot but if not, ah well, capitalism.

Try using adb. If your computer has drivers on it for phone you might able to get into fast boot. If that does not work I would try Sprint store first. Have locked my phone up several times while hacking wife off in progress and have used adb every time. Only time i have been truely scared is when i soft bricked my nexus 7. had to stay at work for two hours after i got off to get it to recover because i was scared of her lol.
---------- Post added at 02:05 PM ---------- Previous post was at 01:57 PM ----------
If you get adb to recognize device you could take chance and officially unlock boot loader. Then flash twrp. There is a thread in general section about having trouble getting official update. It has a stock recovery in it. Trick would be moving files to recovery section of twrp
I have gotten the phone to soft power down and get into fast boot and custom recovery. It's a bit tricky with timing, I usually wait for the screen to go black after soft reset, let go, and immediately hold power and volume down. If you can not boot into fastboot I honestly don't know what you can do either than return the phone.

Thanks for the help Unicron. I think Brandons method might be my only alternative... but you know what? I already have the box packed up to ship back to Amazon! I am still a noob; I dunno if I could go the distance on this one. I have been updating my Android SDK files since I got the phone but I never got it to recognize boot up thru ADB fastboot. disclaimer* I havent tried it in a couple days since all teh SDK updates completed.
I dunno though I am a big time DIYer when possible. If it werent for the massive amount of tape I put on the box and packing label I would already be trying this method. I can't convince myself just yet. Amazon makes it too easy. I could have the *new* phone by Friday. Then I wouldn't be wasting my remaining work week trying to hack into my personal Christmas present in order to make it function...........................................
Edit - Yes I'm impatient. My job is too demanding and I am trying to set a good precedent for 2013. Wasting the first 3 work days on a phone is not how I intend to start off the year. There is probably a valuable lesson to be learned from this as far as hacking experience and to be honest with the responses here I think I could get it to boot up from PC in SDK/ADB mode and go from there. I just didnt know if that was possible until after I made the claim with Amazon. I still have an entire day today and tomorrow if I want to indulge myself. It doesnt matter if I mail the package today or Wednesday, I can still get it by Friday. I believe this thread is still valuable because we have patterns of repeating past failures and I may find use of it when I recieve my new phone and, darn it, it mysteriously bricks as well. in the same fashion.... the only thing I was really trying to do was get all my apps on my SD card... sad huh?
Edit 2 - Opened up the box, tried fastboot and adb, nothing. Off she goes.
I don't blame you, it sounds easier to exchange in your case any way. The main suggestion I have is if you are getting into any type of build.prop or operating system tweaks that have potential to lead to boot loops or cause the phone not to boot, then unlock the bootloader and install custom recovery.
The Moto-fail method seems limited to only be able to run apps that require root. For me this has no use as I want to be able to have complete control over all aspects of the Android OS. There is not a huge mod community for the Q as yet but I believe Cyanogen will be a reality as Interloper continues working on it. I came from an Epic with Cyanogen and soft-bricked it a minimum of 50 times. CWM was very forgiving on that phone, the Q is a lot more finicky and frustrating.
If you have insurance through the carrier then you are going to pay $150 for a refurb if something goes wrong and you hard brick the phone. If you unlock bootloader and install custom recovery then you have a fail-safe in the form of nandroid backups and restores. Then you can mod away with little fear.
Good luck on the new phone and I hope you don't give up after six days of modding with the Q!

FWIW, pressing vol down + power til it resets then pressing the camera button + power once the screen is black gets you to the Boot Mode Selection Menu, where you can start recovery, fastboot, BP tools (still not sure what that is entirely) and some others. Seems to be a fairly reliable/easy method for getting to both recovery and fastboot from any point.

It does work without any recovery mode and I believe it still works without the bootloader being unlocked, I didn't know about this myself until after I had already unlocked it. Sorry I couldn't help out sooner.

Awesome, I am wanting to do the backdoor root method again but, of course, may brick it. I dont think Amazon will keep sending me new ones.... but maybe!

For anyone concerned, I knew it would only be a matter of time until bricking my new device. This damn Root Toolbox Pro did it to me again, and on a simple, menial task. I am going to be working thru the motions on getting this to work.
Using the instructions quoted I did get stock recovery to work or at least flash on the screen for a split second. Seems like there is a timer on the recovery screen. I am having trouble with the fastboot prompt though on the PC. Do I do it in the "platform-tools" folder which contains fastboot or in the "tools" folder of the main SDK directory? I am really a noob, can you give me the cliff notes of how to get into ADB, fastboot, etc on the Photon Q in order to do a factory reset? I already have Android SDK installed and completely up to date so that is done. And Fastboot is installed. I'm just having trouble crossing the finish line here... I can get the fastboot page opened in the stock recovery but from there I'm lost. I dont know what to type into the command prompt, in what directory, or what.... Also when I open the command prompt in the SDK folder on the PC with fastboot in the directory and type "adb reboot bootloader" it says "device not found". Maybe (surely) that is the wrong prompt?
FWIW my phone is showing the dead android guy. I didnt do anything besides try and clear up my Play Store download list which required a reboot. The phone never started back up. I dont know how much damage was done or info was lost or whatever, but seeing as how I was rooted but still locked, I had no custom recovery. So no back ups. Is there anything to restore or am I looking at a full wipe and restore?

As abnormal as it seems, your situation seems pretty normal... at least from my shoes. I went through the same scenario... I didn't know what adb was, or fastboot, etc. So, here's what I know
the fastboot commands work even if adb doesnt see it in the list of devices attached. Somehow it just works (as long as the phone is in fastboot mode).
If you're able to get to the fastboot mode, things should be okay. Just open a windows explorer window to the Platform-Tools, hold the shift key and right click on a blank space within the window, then click open command window here.
you should be able to pass any adb (if the phone is on and recognized) or fastboot (if phone is in fastboot mode) commands from that command prompt.
Also, if you have a stock recovery, CMW, or TWRP image, this is the folder to copy those .img files to. Once you get your phone into fastboot mode and its plugged into the computer, just type into the command prompt:
Code:
fastboot flash recovery recovery.img
If you're just looking to reboot the phone into recovery
If you have a CWM or TWRP recovery just replace the recovery.img with whatever the .img file that you have. Also, as a tip instead of writing the entire file name, just press the first couple letters then press the tab key within the command prompt, it should fill in the rest. keep pressing tab until you get to the .img file name you want.
To avoid doing this again, maybe I can help... what were you trying to do to begin with? From the sound of it, you were trying to root the phone with the Root Toolbox Pro but it bricked, and then you tried to reboot into recovery and then got the red android... ?

As abnormal as it seems, your situation seems pretty normal... at least from my shoes. I went through the same scenario... I didn't know what adb was, or fastboot, etc. So, here's what I know
the fastboot commands work even if adb doesnt see it in the list of devices attached. Somehow it just works (as long as the phone is in fastboot mode).

Thanks for the response. So, all I have to do is: go to fastboot and flash a stock recovery image file and it will automatically wipe the phone, cache, everything, and restore the operating system? Sounds awfully easy! I found some stock files in this post : http://forum.xda-developers.com/showthread.php?t=2001226&page=2 Are these the ones you used before?
Last question: I can flash CWM or TWRP but wont be able to access them if my bootloader is locked, correct? So flashing a stock recovery will allow me to have my stock phone back again, locked and un-rooted? I guess if I cant get it to work with the stock recovery then I can unlock the bootloader and do a CWM or TWRP recovery and then flash the stock .img files?
Thanks again for your help. I already had root with the motofail2go method which I like using but seems like when I try and use some generic root feature from apps from the app store that it will crash/brick the phone cuz obviously those apps are generalized and likely to brick certain percentage of devices....
Ok what does this mean? Something with the bootlaoder obviously. Does it need to be unlocked?
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>fastboot flash recover
y qrecovery1.img
(bootloader) Variable not supported!
target reported max download size of 31457280 bytes
sending 'recovery' (5962 KB)...
OKAY [ 0.479s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.755s
C:\Program Files (x86)\Android\android-sdk\platform-tools>
And on the phone screen it says "invalid image size for partition recovery" twice for both times I tried this method.
You will need to flash the system image as well if you want those, as the recovery image will only flash the recovery. The files in that link are for twrp only... so you'll have to be able to get there first.
With the custom recoveries, I'm not 100% sure whether or not you will be able to use them without being unlocked. I would wait to see if anyone else can answer that question for you, but if you did try it without an unlocked bootloader, you at least have the stock recovery to fall back on if needed.

I'm thinking it could either be that your phone is full and the image you're flashing is too large to fit on the space available...
Or you're trying to flash custom software on a locked phone.
Hopefully someone is able to answer that a little better...

You can't alter the stock recovery (flash a custom recovery like twrp or cwm) in fastboot without having the bootloader unlocked. Your options are to unlock your bootloader, flash custom recovery, create a backup of your current setup, download one of the stock working backups, place it in the backups folder for twrp on your external sd card, and restore one of the known working backups in the development section (befrosty linked to one). Or you could use RSD lite to return to stock using a stock factory firmware flash. That involves connecting your phone to your PC and flashing the phone back to factory stock. Information on RSD Lite and links to the FXZ's can be found here.

Phone booting to secure fail:kernel

Okay so I didn't do the proper research when attempting to root my mother's phone.
She was on 4.3 already (must've updated automatically at some point)
What I did was first root it using the 4.3 root method. Then I realized I couldn't flash a kernel without a CWM. So I tried to flash CWM via terminal. When I tried to boot to recovery it was giving me Secure Fail: Kernel, I figured that I did something wrong. I flashed it again using GooManager. Now I pressed reboot recovery and same thing. So I realized I wasn't unlocked yet -oops.
I was going to download ez-unlock then but now, unlike when I flashed TWRP from terminal, I can no longer boot up the phone. Even without holding the vol up+home+power, it always starts to say booting recovery and I end up at the Secure Fail: Kernel screen that says "System software not authorized by VZW blah blah"
So did I brick her phone? And is there a way to fix it? I figured maybe I can odin back to stock or something?
There are more threads here about fixing a bricked 4.3 phone.
Try getting into download mode first with vol down-home-power method. If the phone will stay in download mode, then you should look into reflashing things back to stock to unbrick. On this forum area there are a few threads some sticky check them out

Wow. I appologize for not searching properly. It is actually somewhat embarassing that it is the top sticky. I must've looked through 5 pages in general and forgot to check this forum. Sorry about that.

problem with rooting my nexus initially locked and unrooted nexus 5 with wugfresh nrt

hi .i had a non rooted locked nexus 5 with marshmellow on it.i tried to apply wugfresh2.0.5 root .the drivers test was succesful.then i unlocked and then engaged to rooting.but during the procedure at the end after flashing the busybox and 2 other files my phone is stuck in the 4 moving shapes screen without being able to reboon and start...help!
I'm not being a jerk, but you need to be in bootloader/fastboot mode, flash the factory image to recover the phone. Start from scratch.
Then learn how to flash, root, and use ADB properly. This is exactly why I'm against one-click programs, the end users mess with things that they don't fully understand and wind up with bricks.
Good luck with your device.
Hi, open Wugs rooting kit, Connect your phone to Laptop, now boot into recovery mode(Long press the power+Vol up+Vol Down key simultaneously for some time and your phone will restart, while it restarts , press the volume down key +Power before the screen starts, . It goes into recovery mode. once you are in recovery mode, choose the option in wugs to restore the the device to original and choose the option "Phone boot loops" and click on restore or unroot button. I think it should fix it

I partially agree.
To flash a factory image, the device needs to be in bootloader/fastboot mode.
Would you please edit your post, so that it doesn't confuse anyone? Thanks.

Failed root

Hey,
Tried to root my phone and things got messy.
I'm at a point where when I try to access the bootloader I get the "No command" screen, which I can bypass with the Power+Up keys and reach the "Android Recovery" screen.
I used "Wipe Data/Factory Reset" which didn't help much.
I can't do much more than that because Windows doesn't recognize my device and so I can't apply anything through ADB.
I tried to install the drivers again, but still nothing. My phone doesn't appear on the Device Manager.
Windows does make a sound of connected USB when I enter bootloader, but soon as it hits the "No Command" screen I hear the sound of a disconnected USB device.
Any idea how to make Windows recognize the device again so I could try to install things back with ADB?
Thanks!
OK, managed to solve this part after some reboots.
I'm now failing to ADB the stock image.
The phone says on top of "Andoird Recovery" that it's 7.1.2/NZH54D.
That's the stock image I've downloaded and when I try to ADB it I get on the windows terminal
"cannot read 'sailfish-nzh54d-factory-127f0583.zip'".
How do I move on from this?
OK. Figured this one out as well.
I was flashing the wrong file. Needed to flash the OTA file "sailfish-ota-nzh54d-2163742b".
Now I have my Pixel up and running. OS seems to be there.
BUT... bootloader still not there. I still get the "No Command" page when I enter the bootloader and can only use ADB.
How do I move on from here? Still wanna root, add twrp and a different ROM.
I would start over from scratch. This guide is really good, it's for Pixel XL, but should be interchangable for Pixel 1 (non-XL), just be careful of the model specific files (salefish vs. marlin)

Can't you acces bootloader with "adb reboot bootloader"?
Also make sure u switched on usb debugging in developer options.

If you get to the screen where you can choose to enter recovery, that is the bootloader. The no command thing is something you always get when you choose to boot to recovery. When on the screen before the no command thing, plug it into your PC. If the PC recognizes it, use fastboot to access it. "Fastboot devices" will show your phone. Adb devices doesn't work there. Bottom line is, it sounds to me you're getting to the bootloader. Just not realizing it.

The no command screen is a part of the recovery, not bootloader. My easiest suggestion for you is that with the phone powered on press the power button and select restart. Once the screen goes dark, press and hold volume down until it boots to the bootloader. If you can't get that to work then you sir have a problem.

Yup. I think I'm good now. Gave up on the ROM thing. Too much headache to maintain it. Sticking to stock. Imperfect, but less headaches.
I wanted to root my device mostly for Titanium backup.
The rest isn't that important to me.
Thanks for the help!
