Deleted Recovery mode and OS. How to recover? - One (M9) Q&A, Help & Troubleshooting

I tried to install an 2.10.401 RUU via the SD card method, but the zip was corrupt and didn't work. Now I can't go to the recovery mode, it shows a red triangle, and my phone can only boot to the bootloader and to the download mode.
I tried to install a TWRP recovery, but when I type
Code:
adb devices
into the command prompt it doesn't show my phone.
Is there any method to get my phone back?
Any help is appreciated!

Use fastboot, not adb. Adb only works in adb mode through the ui.
Read some of the FAQ/guides. You'll figure it out.

And If I get the recovery back what do I do from then?

Flash a rom, of your choice like http://forum.xda-developers.com/one-m9/development/rom-viperonem9-1-0-0-tweaks-hub-t3072773

Stock 5.1 rom for wwe phones. Not tested but from original link on website.

I wish I stole my HTC M9.

Thank you all for the help, I flashed the stock recovery, then TWRP via fastboot. My phone works again

Yo bro. I'm using an htc u ultra. In the process of flashing twrp. After saying it was successful. When I go to the recovery mode of my phone. I see like a phone sign. And then after that my screen goes off. And the only way to bring back my phone to the bootloader is by giving the command. "adb reboot- bootloader ". And then I can go back to my phone normally. I can't access twrp. Idk if I even installed it correctly. But I followed all the steps. And everything. But no result
This says I deleted my recovery and idk what to do. Please guide me

Help! Have I screwed up my bootloader?

So in the rush to get CyanogenMod installed on my newly-S-Offed phone, I downloaded CWM from the appstore and started looking through the various devices to flash ClockWorkMod Recovery to. I selected the vanilla HTC One, not the verizon-specific model. I have not yet rebooted my phone yet, but I am worried that doing so will brick the phone since I technically don't have the right bootloader. Looking through CWM's list on my phone, there is not a verizon-specific model bootloader. There is one on Cyanogen's site (can't post the link due to XDA restrictions), but it appears to involve rebooting the phone. How should I go about safely flashing a good bootloader onto my phone?

CWM is a custom recovery, not bootloader. Download your choice of CWM or TWRP, reboot into the bootloader and use Fastboot to flash it.

I am referring to ROM Manager from the android app store. When you bring it up it asks you to flash your bootloader. The bootloader I selected was the one for the Vanilla HTC One.
I don't use ROM Manager, but I just installed it on my phone. The prompts all refer to recovery, and make no mention of bootloader. See below.

Its most likely referring to the recovery, not the bootloader; Assuming you're root, Rom Manager is there to flash custom ROMS and custom recoveries. I don't think you'll have bricked your phone if you installed a bad recovery, but I think your best bet would be install a compatible one manually.
SO pick a thread and follow the directions under installation:

Well my phone will reboot safely, which is good.
However, rebooting into fastboot or recovery just reboots into normal mode. Recovery will say the first time that it's going into recovery, but will reboot again and go into normal.
Thoughts?
Success! I just had to keep scrolling. there was a version in Rom Manager, all the way down at the bottom under "m7vzw." Flashing that did the trick.
Thanks for the help.

The S-Off exploit removes stock recovery, so it will go nowhere until you flash CWM or TWRP. Fastboot will work regardless.

All that said, I can now boot into recovery no problem, but typing "adb reboot fastboot" just reboots the phone normally. Any idea why that might be?
I've never used that command personally. I have Quick Boot (Reboot) from the market and use it for getting into recovery and fastboot from Android.

adb reboot recovery = takes you to recovery
adb reboot bootloader = takes you to fastboot/booloader
I don't believe adb reboot fastboot is a command, so it just does adb reboot

New Verizon HTC one S-off but can not access recovery

I just got an HTC one from Best Buy Mobile (Verizon) yesterday. Turned S-Off using runrunner. Verified root but can not access recovery. I had the same issue with a S4 but it was a known issue for all that has updated to the 4.3.
I have tried all the suggestions in flashing TWRP. I am wondering if this is a Verizon related issue? Maybe they are putting something on their phones to prevent recovery?
HELP!!!!
Something is really jacked up with my phone. It kept saying Unfortunately Amazon has stopped. Over and over again. So I gave up and went to do a factory restore and data wipe. I first went to Super user and removed permanent root. I then tried to do a factory wipe through settings/backup & reset reset phone. It still gave me issues trying to enter recovery mode. It would get hung up and then reboot to a sort of safe mode version of the OS. (with a red disclaimer at the bottom). Then I tried to do factory reset by holding the volume down and power. Its doing the same thing. At this point I don't are about root I just want a working phone.
Any suggestions?

OK, so you are s-ff, is your bootloader unlocked?
IF you are not on stock recovery YOU CANNOT run an update

.. you have to have a recovery..
I think?
can you successfully fastboot flash a custom recovery? If not can you fastboot the stock recovery..?
To be completely honest, I would just run the RUU. should fix you right up
You could boot into RUU and flash the decrypted stock rom zip to get back to straight stock. The zip reflashes stock recovery. I don't see why that wouldn't work.
Edit: Oops. Didn't even notice andy just recommended the same thing lol. My fault.

Thats odd, i thought you had to have a recovery of some kind.
Here is what I would do:
Lets try Flashing CWM instead of TWRP in fastboot I will post it, and I will also post the stock recovery there to as well.
https://www.dropbox.com/s/kk2esdrx1g1b50p/recovery-clockwork-touch-6.0.4.5-m7vzw.img
the image is easily installed via an unlocked bootloader with the following command:
fastboot flash recovery imagename.img
in this case: fastboot flash recovery recovery-clockwork-touch-6.0.4.5-m7vzw.img
See if it actually takes, and report back any errors.
If for some reason it does not, try booting into bootloader/fastboot then push the stock recovery:
https://www.dropbox.com/s/hgzgq84svzahvnv/htconerecovery_signed.img
Hopefully that will at least take and try to push CWM again , reboot bootloader and reboot into recovery . I am hoping that does it for you.
Go here: http://download.chainfire.eu/370/SuperSU/UPDATE-SuperSU-v1.80.zip and dump SU on the root of your SD card and flash the SU.
I have seen people have all kind of weird issues with rum runner and I am just glad i had the official java card method used on mine. I also tend to just use a stock ROM which is just de-bloated.
Anyways I have used Santod040 roms in case i need to go back to pure stock ROM only: http://forum.xda-developers.com/showthread.php?t=2485319
You will need the odex one to run any OTA
The firmware is a different thing to flash.

Thanks guys!
I was able to install TWRP and also Superuser.
Here are the instructions I used. Maybe they will help someone else like me.
Power off your device, then press and hold Power and Volume Down until you're in the bootloader menu. Highlight FASTBOOT and press Power. You should see Fastboot USB highlighted in red.
Download the latest version of TWRP for your phone and carrier. Rename file to twrp.img.
Open a command prompt on your computer and navigate to your SDK directory. Type "fastboot flash recovery twrp.img" and hit Enter.
Then I backed up my stock rom using TWRP
In TWRP's main menu, tap Reboot. It will tell you that you're not rooted and ask you to install SuperSU, so swipe to confirm. When you reboot your phone, you should see a notification that you need to install the SuperSU app. Open the notification and select TWRP, since the app from Google Play only works with S-OFF.
Worked flawlessly.
I installed NuSenseONE max and I love it so far.

how else were you trying to flash a recovery ?!?
Goo.im app as well as ROM Manager, ROM Toolbox can flash recoveries. I've notice there isn't much compatibility with the m7vzw though. You can also use terminal command's from the device. All of these require root access though.

Hey everyone, so my problem is that i did run rumrummer the way it said on the directions and i double checked my rom version type countless times. It says that i am unlocked and s-off, but i cant access recovery. I tried flashing recovery with fastboot command prompt, and still no luck. It gives me a "error: cannot open 'open.img', I navigated to the folder that it is located in and executed the command properly every time. I also dont know how to flash superuser using flashboot, so any help will be very much appreciated. Also I'm kinda new to rooted, I have some experience from a few years back, but dont remember everything.

place the name.img file in the same folder as the adb and fastboot executables, open command prompt as administrator for that directory, then type "fastboot flash recovery name.img" substitute name.img for the actual name of the file including extension and make sure there are no quotes around it. also, use "fastboot devices" or "adb devices" to make sure your phone is being recognized.
I got it to work, finally. Thanks for the reply pointedge. I beat u to it earlier in the day and forgot to post up again that I got it. It was like u said, I just had the file in the wrong folder.

[Q] HELP! Stuck in TWRP boot loop!

Howdy Everyone,
So just tried rooting my new m8 and now I'm stuck endlessly booting into TWRP. I thought I did everything correctly: Unlocked the bootloader, installed the USB drivers, installed the ADB fastboot drivers and then flashed twrp 2.7.0.3. I get to the the htc logo screen/warning and, bam, back to twrp everytime.
Does anyone know how to fix this??? The last time i was rooting and installing custom mods was back in samsung galaxy s2 days, so my knowledge is a little dated. Please help!!

I encountered this issue as well. I'm almost certain that when you were flashing recovery, you used this command "fastboot flash boot recovery.img".
The right command should be "fastboot flash recovery recovery.img".
To rectify the issue look for a tread that has the boot.img for your specific M8 model and flash boot back using " fastboot flash boot boot.img".
This should fix the issue you are having

I followed the instructions on the TWRP site:
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.img
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p43
Then reboot to complete installation.
But that left me in a TWRP bootloop. Can you please give me step by step instructions on how to get out of this bootloop?
Thanks!
First off, being a noob and using dd without even knowing what partiton you're writing to is extremely dangerous.
Just use fastboot.
plug phone into PC in fastboot mode.
Code:
fastboot flash recovery twrpfilename.img
fastboot erase cache
on phone go back to hboot, select, recovery
In TWRP go to wipe, then swipe for a factory reset (Advanced wipe cannot properly wipe cache and dalvik after fastboot erase cache)
then go to advanced, select cache, dalvik and system and swipe to wipe those partitions.
then go to install, select the rom on your phone and flash. follow on screen instructions.
If you don't have the rom on your phone for whatever reason,
connect your phone, while in TWRP to your PC then, using adb on your PC
Code:
adb push romfilename.zip /sdcard/
Wait until it completes with bytes sent.
Then flash using method listed above.
Be careful if you want to keep your phone. I stress this, if you don't know what a command you are issuing does, exactly, DO NOT DO IT until you look it up and understand what you are doing. There is great risk even when you know what you're doing. There's a LOT more when you don't.

You need cwm recovery to factory reset from cm roms.
Also you need to be in FASTBOOT mode for it to detect your device.
Boot to fastboot, erase cache, reinstall twrp.
Next time reset/wipe from recovery.

New Z00A ZE551ML 3.15 firmware can't upgrade OTA manually
I have the same problem, although it is not likely the drivers.
When attempting to sideload the full firmware image, it errors out after a few seconds, stating that it cannot detect the device. I reboot the phone manually, then reboot bootloader from command prompt. try again and the same thing happens. First, I tried placing the file on an sd card, renaming it to MOFD_SDUPDATE but it failed after 25% and left me with the screen showing the "unplugged" icon. Now I cannot enter recovery at all. Attempted root, tethered, untethered, and no luck with any. I used an app before trying any of this to make sure it was not rooted or unlocked already. I'm running out of ideas. When I get home, I will try flashing just the droidboot.img as suggested in this thread: http://forum.xda-developers.com/zenfone2/help/unlock-bootloader-read-fix-t3138837.
Any other advice would be greatly appreciated. As I said my phone has

Can't enter recovery 551ml...Z00A

Hi
Problem is that I can't enter recovery. I am able to enter fastboot menu, but when I'm choosing recovery mode, phone like restarts and goes again to fastboot menu...no recovery mode or dead bot with error comes. Below is blue writing "continue the fastboot process".
This happened after I tried to install twrp through twrp manager...it was installing twrp and said that install succesful.
Also tried fastboot command "fastboot clear cache", but nothing.
So, you didn't unlock the bootloader and removed your recovery...
1st thing, go to bootloader mode, download the recovery for your version of Android, eg 2.20.40.168, and flash through fastboot on the PC.
Put phone in fastboot (bootloader mode) - I'm assuming of course you have the latest Intel drivers and the flashing tools - and through the CMD interface (agasin flashing tools) type "fastboot devices". If you did it right then you'll see you serial number...
Now, in the same folder as the fastboot tools, have the recovery.img ready and type "fastboot flash recovery recovery.img".
You should now have recovery again...
2. If you haven't done so, lookup how to unlock bootloader before trying this again and do it. Make sure everything goes as it says, particularly important the splashscreen that says ASUS turns white, and you should be ok to flash TWRP though I use PC as I find everything seems to work.
Yes, it was my mistake, i didn't unlock bootloader and tried to flash twrp.
Now i can Go into fastboot and phone connects to pc easily.
But so far i didn't found recovery image for 2.20.40.174 fw.
But can you confirm that it's possible now to use one click bootloader unlock and then flash twrp? Without flashing stock recovery.

You can use This Apk to unlock bootloader.
Once unlocked it will reboot and show white splashscree,then you are ready to use twrp.
Try it
If you go to the pre-rooted rom thread you can download ALL the img files - rom, recovery,boot and droidboot.img. I'm pretty sure 174 was there in the Mega link at the top of the 1st post...
Just download the recovery.img as that's what you need...
Ok, thanks to all. Now bootloader is unlocked, twrp installed and installed rom blisspop. Great phone when there is no bloatware.
Sent from my ASUS_Z00A using XDA Premium 4 mobile app
Cool, glad you got your toy working again...
Same issue as sir Jaguar
Already installed .img trough adb says succesfully installed
When i go to recovery mode no deadbot no white splash screen load.
Tried the asus unlocking tool provided by the asus and the same link provided by sir Ultima still no good results.
Im already at 174 fw
Tried the twrp apk
Tried flashify
Tried diffrent kind of .img
Tried to re install the image using ADB
Still no good results
I think its the bootloader that has the problem.
Guys plz help tnx
thank you for your hard work!! love it
you can try to reflash the corresponding version of stock recovery.img

Hi there, I have a similar problem i think. I have unlocked bootloader.
My problem is PC won't regonize my device. I installed the driver for intel asus adb but it would says "error: device not found" for fastboot cmd.

Hi, Also have my phone on the same conditions but If I try to flash anything I got permission Denied.
Please help me
