[Q] fastboot - no boot or img file

hey guys i'm having some trouble. i just got the nexus (it's my first smartphone, ever) and i've tried to hit the ground running. here's what i've done to the phone so far.
i got all the drivers running on my win7 machine and also installed the android SDK folder onto C: as was described in this thread: http://forum.xda-developers.com/showthread.php?t=878786
i then unlocked the bootloader using the above guide as well. when I power on the phone using UP+POWER it says UNLOCKED.
I then proceeded to follow this guide: http://forum.xda-developers.com/showthread.php?t=875875
i used ADB to flash the clockwork crespo recovery. i then used fastboot to install Superuser.
at that point i had an unlocked bootloader, clockword recovery image and superuser permissions.
i then saw that the 2.3.1 update had been released. i wanted to learn how to tackle that so i started reading up. i noticed that people were using ROM Manager and Titanium. I got titanium and installed the BusyBox addon and it allowed me to do a full Batch Backup of all my programs, etc. i've got the 50MB or so backup folder on my PC now.
anyway, i then messed with Rom Manager. I installed the 3.0.0.0 ClockworkMod Recovery and everything went smoothly. now this is where my troubles begin.
when i go to Download ROM all i get is a Free Stuff area.
when i go to Check for ROM Updates it tells me my device isnt set up for OTA updates.
those are just minor issues.
this is the big and scary issue i have:
when i click on reboot to recovery, it takes me to the same screen that i go to when i power on with VOLUME UP+POWER. it doesnt take me to the recovery screen that i see in various youtube videos. instead, i'm at the main screen where it says UNLOCKED and i have 4 choices (reboot bootloader, recovery, reboot, power off). and on the very top in RED letters it says fastboot - no boot or img file. <-- this is the part that makes me nervous. If i manually power down the phone and boot to fastboot and click recovery, it just goes back to this same screen and says fastboot - no boot or img file. when i first rooted the phone, clicking recovery actually took me to a different screen where i was able to load up superuser.zip and install it.
did i accidetnally delete something that i wasnt supposed to? did installing ROM manager mess something up? i typically dont do anything until i confirm that i am supposed to. i think the problem is that i dont yet know how one thing i do on the phone affects another. i'm guessing when i used rom manager to update the CWmod it changed some folders/files? i dunno!
otherwise, the phone works fine and there are no glitches or hiccups or crashes. So if someone can please take a moment to just explain to me what i did wrong or what i failed to do i'd really, really appreciate it.

you don't have a recovery partition. Either flash one over manually using fastboot, or boot up and try to use ROM Manager to flash CWR.

when you say flash one over using fastboot, do you mean put my phone using VOLUME UP + POWER, connect usb cable, then use command line to do this:
fastboot flash recovery recovery-clockwork-crespo.img
?

Yes, 'cept it will be "fastboot flash recoveryrecovery-clockwork-3.0.0.0-crespo.img" without the quotes now.
But does it say that you're missing a boot.img or recovery.img?
Also, the "not set up for OTA" thing isn't for official OTAs. Some developers have made their custom ROMs capable of being updated that way.

thank you luxferro and unremarked. i did it and it works perfectly. i am now able to access clockworkmod recovery 3.0.0.0. next step is backup my existing ROM and also to figure out how to put the OTA 2.3.1 on and restore all my data
oh and unremarked: it basically said no boot or img file and thats it after i would click on recovery or reboot to recovery trhough rom manager. it was just in red at the top. but now it takes me to the ClockworkMod Recovery

help with cyanogen Rom upgrade from 5.0.7 to 6.0.0

I have a rooted mytouch original with cyanogen 5.0.7/android 2.1 and want to upgrade to cyanogen 6.0.0/android 2.2.
Can I just install the new rom, or are their prior steps to prepare for this.
Thanks

Check CM wiki.. all the info is there!

yes, I had already read through the cm wiki before posting. I just read through it a second time, though the specific question that I had asked was not addressed as far as I could tell. Don't want to flash a new rom without first knowing its the right step to take. So if someone doesn't mind answering the question...

Just do a nandroid backup. Then you flash the CM 6 over the old one, do a cache+dalvic wipe and start it up.... It should be ok.
If not, then just revert back with the knowledge that you have to do a complete wipe, meaning that you need to start from scratch.

I now have initiated flashing new rom, starting with backing up data and wiping cash. However, I am now unable to go into recovery mode, whereas the phone is stuck on the logo when attempting to do so. I had installed through rom manager clockworkmod 2.5.0.1, got the message it installed correctly.
Here are the methods I have used to go into recovery:
1. click on "reboot into recovery"
2. backup current rom
3. flash alternative recovery with RA Recovery v.1.7.OH downloaded by rom manager, and use rom manager to restart into recovery mode
4. turn phone off, try to press home and power button together, for the new RA and the new clock work mod programs.
will not go into recovery mode, gets stuck on the boot up logo. Phone otherwise works fine, on the older Cyanogen Rom..., just can't go into recovery mode which I need to do to upgrade.
My original recovery was RAv1.2.0G.img, but this was I assume replaced by the rom manager.
In case this is important, my other software versions I have been using the past year:
Hboot 1.33.2005 (sapp30000), Cpld 10, Radio 2.22.19.261
will not go into recovery mode, gets stuck on the boot up logo. Phone otherwise works fine, on the older Cyanogen Rom...
any suggestions?

You flashed wrong recovery version...
You need RA Recovery v.1.7.OG and not H as stated above.
If all ****s up, then use my guide (check my signature) to flash a custom recovery... just skip the steps about root since you already got that!
Remember, G and NOT H.

lost recovery
mumilover
I do actually have v.1.7.0G installed, not H (my bad).
it just will not go into recovery.
Please let me know where your guide is, but right now I have been unable to communicate with my device through my xp desktop, get the "device not found" error (I assume you are suggesting that). Not sure how this will help though, since I already seem to have the correct recovery image installed.
Any help you can offer would be appreciated.

Download my fastboot commander (CHECK MY SIGNATURE, magic version).
Restart into fastboot mode.
Download this recovery image:
http://rapidshare.com/files/387932919/recovery-RA-sapphire-v1.7.0G.img
Using the tool and your eng spl, you can just flash the recovery image on the phone.
Just use the first tab -> recovery button -> navigate to the above image -> click "flash recovery". Done.
Restart into recovery by home + power combo.
You could also try this command:
Code:
adb shell reboot recovery
to force it to boot into recovery from the system.

[Problem is fixed. Thanks for your help.
I used my mac bootcamp (could not get sdk to run on my desktop or mac), and could find my device through adb. Then I pushed a separate version of the RA 1.7.0 G (the one the came with rom manager did not work!) to my phone via flash command. Voila, I am now able to go into recovery mode. 6.0 is installed and running.

" x " appears on the screen

Malfunction " x " appears on the screen !! help me what is going on

Haha... you'll need more information than that if you want real help.
Based on the limited information though I suspect your phone is stuck in a bootloop. I'd hook it up to the PC via USB and check the logcat. Probably something screwed up.. Maybe time to restore your latest backup.

Did you flash any ROM if so, did you clean your Dalvic+REgular Cache

If you don't have an Recovery:
- Connect your Micro SD on PC
- Download and insert on SD the stock ROM of your Nexus One
- Power ON your Nexus with Volume Down Pressed.
- Autmotically Restore Nexus (You should say Yes xD)
At this time, you decide if you want to be root and install other ROM

you better just list your setup info before doing anything
locked/unlocked bootloader
rooted/unrooted
which recovery are you using
what rom are you running stock/custom
what were you doing when this happened
a couple safe things you can do in meantime is to pull battery and reinsert and power on
if it goes back to X, pull battery and DO NOT power on. Hold down the pwr button and trackball at same time and see if you can get into recovery
the third is hold down trackball/vol-/power at same time while X is on screen and see if you can get to recovery that way
if you can't get to recovery you will need to fastboot new recovery, assuming you are unlocked
once you get into recovery do a nandroid if you are rooted
and copy it to pc as a secondary backup
it is possible you may need to try the passimg method in wiki
http://forum.xda-developers.com/wiki/Nexus_One/Guides_&_Tutorials#Unroot_.2F_Restore_your_Nexus
also to do fastboot commands you need usb debugging selected on phone--hope it is

Hello, i have a similar problem with my n1
the phone starts and just shows the nexus X - (waited for 15 min. nothing happend)
i can go to the bootloader / fastboot menu with PWR + (Vol-) but i can not go to the recovery mode. -> the phone reboots and get stuck at the X
the phone is rooted
blackrose / hboot 7.35.5017
radio 5.12.00.08
recovery was ext4
i had a german ics miui rom installed and tryed to install the latest ics miui us rom after it didn't booted the miui us rom i turned the phone off and tryed a few hours later to turn it on to reflash the german ics miui rom.
1.)
i tryed to install a new recovery image ->
recovery-clockwork-5.0.2.0-passion &
recovery-RA-passion-v2.2.1
(still get stuck at the X if i try to go to recovery mode)
2.)
i tryed this one with the passimg.zip but nothing happens if i put in the sd card :/
(with nothing i mean the green text show that the sd card is checking for PASSDIAG.zip and PASSIMG.zip but dosn't found it)
i also tryed:
3.)
erased boot
flash boot from passimg.zip (PASSIMG_Passion_Google_WWE_2.18.1700.1_FRG83_release_signed)
4.)
erased cache
erased userdata
started again with 1.)
5.)
got frustrated and erased system -.-
any ideas?

study it ,thank you
study it ,thank you

Hmm, sorry if its obvious but i have no idea what it could be or what i have to search to find the solution. Would be nice if you could give me a hint. Of course im not asking for a step by step solution. Thank you.
Send from my awesome SE K800i

not sure why you are flashing boot images
do you have a nandroid--copy your sdcard with the nandroid to pc--all of sdcard
are you flashing thru fastboot in command window
did you read my post above on getting to the fastboot screen--can you do that--the one with the 3 androids
pwr/vol-/trackball same time, may take 20-30 seconds
if you can get there, put your recovery image in your fastboot folder on pc, normally tools--assuming you have sdk installed, your phone must have usb debugging checked--I hope
open a command window and change directory to the tools folder or wherever the fastboot.exe file is. Something like:
cd/
cd/ android/android-sdk-windows/tools for me
then on same line type
fastboot devices (it should show your phone H#)
fastboot erase system
fastboot flash recovery recovery.img (or the exact name of the recovery image, checked by right clicking on the img file in your tools folder and looking under properties)
I would use amonra you listed above and check the md5 if possible
hopefully the recovery will flash
if not you can go to the wiki link i posted above and try passimg metthod from there, use correct one. don't add the .zip. Windows will had it automatically.
a side note, DON"T flash different roms without wiping all including System 3 times before flashing--prevents a lot of problems

How to flash TWRP and Root Moto X Style on Marshmallow

I am using moto x style and unlocked bootloader with 'Windroid Universal Android Toolkit' v2.5 but cannot flash TWRP and root this apl. Today I tried flash TWRP and then root but after showing 'Congratulation' pop up,my phone stucked on 'No command' page. I tried twice and same result. Later i check there is either no TWRP or root by SuperSU. And i see youtube video and and read many XDA forum and comments and most of the users says the phone stuck on M logo page when reboot after the root process. And all says its a issue with Marshmallow. And most of the xda posts and youtube video are made during 5.1.1 so there is no problem in that video during flash TWRP and root. So i need a seamless process to flash TWRP and root on Marshmallow so that it doesnot stuck on M logo. And I dont want to downgrade to L for root. And unluckily if it stuck M logo thwn what to do to go back to home screen?Thank you.

Look in my sig...

It's in my signature... There are multiple links to what your looking for and other threads, if you are on computer they should be immediately below the message, if you're in the XDA app you have to look in the user profile (don't think it's possible in Tapatalk though).

My build no is 24.49-18-4. So is this process suitable for this build no? And still i dont flash TWRP. I tried with "Windroid Universal Android Toolkit app" to flash TWRP. though it showed a 'Successful' pop up but it didn't. Can I go with any old process to flash TWRP or u have a new process?

Step 1 - Stop using toolkits! They rarely work right on modern Android devices. With the Moto the only safe, reliable way to root is manually.
I don't know what the 'old way' is to flash TWRP your referring to here... I recommend one time booting twrp with "fastboot boot twrp.img" command (replace twrp.img with your actual twrp image file) then perform a backup to the SD card or USB OTG device and put it away for safe keeping. Then flash twrp either with twrp you have booted, or manually with "fastboot flash recovery twrp.img"
The rooting method I linked before is valid for all Marshmallow builds, if you have Lollipop or Nougat you need to find a different method.

On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:
adb reboot bootloader
You should now be in fastboot mode.
Download the correct image file and copy the file into the same folder as your adb and fastboot binaries. Rename the image to twrp.img and type:
fastboot flash recovery twrp.img
fastboot reboot
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
I am saying about this official method which is on twrp.me site. And after typing 'fastboot reboot' what I have to do to go home page? Sorry to ask u so many things. Actually I am totally new in this thing and very much worry after facing issues 2-3 times. And thank u very much for fast reply.
One more ques, I have unlocked bootloader with that "Windroid Universal Android Toolkit". Now in fastboot it shows 'bootloader unlocked,code 3' is that ok? As u say toolkit doesnot work on modern devices.

So Moto is a tad different... After you flash recovery, do not reboot with fastboot, instead use the Vol Dn key select Recovery and press Power to start it. When the splash screen comes up, allow changes to system, then I the TWRP main menu select Reboot - Recovery, the device will start TWRP again and it should be "locked" in. From there perform the rooting.

That mean after typing fastboot flash recovery twrp.img press enter and then i can plug off the usb keeping my device on fastboot then changes to recovery and do the rest?
Btw suppose if i dont want to root it at that time,then what i do? I mean just after flash recovery how to go to home screen without rooting?
And when i want to perform root process later,after installing SuperSU zip if I press power button and vol down then may I go to twrp recovery or ph stock recovery?

You don't need to root if your going CM, flash TWRP, backup, and flash CM. You don't need to over complicate it.
If you boot (not flash) TWRP and backup then get a copy to safe place there is little risk of anything going wrong.

Ok. But is there any regular chance of going wrong during flash TWRP or flash CM? I backed up all internal important data to external sd card and when I perform these process I just remove that sd from phone.
You pls tell me how to go to home screen after flashing TWRP?
And if I need to root it later then also what to do then? I mean if then I press power and vol minus then will I get TWRP recovery to root it or it will be redirectred to phone custom recovery?

There is always a chance of something going wrong, no one can guarantee everything will be fine. We have had people do everything perfectly but something happens and it's bricked... It's rare but does happen.
After you flash TWRP in the bootloader, press Vol Dn until it says Recovery and press power to start it, after several seconds you will get a screen that will ask if it can write to system, select yes, the next screen will be the TWRP home screen.
Once you flash TWRP, your stock recovery is gone, but you access it the same way... Power off, press and hold PWR+Vol Dn and in the bootloader menu select Recovery and press power.

Your last two are redundant, either flash or boot, you don't have to do both, but each has a purpose... Flash is permanent, boot is transient and will disappear on a reboot.
Boot TWRP first, the first time it will not take you to the main page initially but show you a notification page asking if you want allow it to make changes to the system or keep it read-only, this time only do not allow changes... Then the main screen of TWRP will be displayed and you should do a full backup of all partitions to the SD card.
Flash will just write the recovery partition, it doesn't start anything, you select recovery from the fastboot menu to start it.

So after "fastboot boot twrp.img" i have to allow to make changes and have to do a nandroid backup. After that will I get option to "Reboot?"
And later when I went to recovery I will get twrp page instead of stock recovery? 1st I think I should flash cm13 then root then upgrade to 14.1 bcz still a feel little worry to root it on stock rom.

No, almost every part of what your saying is wrong...
Boot twrp and do not allow changes first time and backup. This will give a clean backup to restore from if things go badly.
After this is complete, in TWRP go to Reboot menu and select Bootloader, flash TWRP, do not reboot but use the bootloader menu to start TWRP. This time allow it to make changes to system. At the main menu if twrp go to Reboot - Recovery the device will restart and TWRP will load automatically, this step will lock in twrp so the stock OS doesn't replace it.
You only need to root stock rom, you don't need to root CM roms as they are already rooted (there are a few roms that are not pre-rooted but they are rare and none of the ones your talking about). As far as CM 13 vs 14.1 I can't really help you but from I've read both are stable enough for a daily driver device.

No, almost every part of what your saying is wrong...
Boot twrp and do not allow changes first time and backup. This will give a clean backup to restore from if things go badly.

Nokia 6.1 plus Stuck on TWRP Splash screen. PLEASE HELP!!

Hello everyone,
I have recently unlocked the bootloader on my Nokia 6.1 plus, and rooted it. I then went ahead and installed TWRP ( App install method - found in the twrp website ). However after I rebooted my phone has been stuck on the TWRP splash screen , I Tried going to download mode , and that just got me back to the twrp splash screen. I turned off the phone and powered it on again , same result . Whatever I do it just keeps going back to the TWRP splash screen .. What is even worse is that my device can not be recognized by my pc while stuck on the splash screen , thus I can not use ADB or Fastboot ...
I am feeling really hopeless and stuck , Help would be much appreciated!! Thanks

Now, dissemble the device and enter edl mode

You shouldn't have installed TWRP on a A/B device let alone install it via the app. It's okay, We're here to help.
If you have OSTLA in your PC, Just open it up and load all files and select to flash the stock ROM. Select Normal Download/Erase User Data options and if the option to Chech AP status is enabled, Disable it. Select on start or the option to flash stock ROM.
Power off your phone completely. If you can't, Then press the volume+ button and power button. Once the screen goes off, Immediately connect phone to PC.
Phone should now reboot into download mode and stock rom should start flashing. Then it's just a matter of waiting for it to flash and reboot.

I had a problem in that my device would never be recognized by my pc even when i finally manage to put in download mode, However after many days trying I was finally able to do it , and to use OSTL.... so thank you!!
I am wondering now how I will do the thing i wanted from the start which is to flash a kernel if i shouldn't use twrp?

So to my understanding what you want to achieve is flash a custom kernel on stock rom. And after you messed up your stock recovery by installing twrp, if you have flashed stock rom using ostla then follow these steps.
First without tampering anything finish an ongoing/pending ota/sp update cause after you install custom kernel you phone won't be able to install OTAs. The last sp is of june so install that.
Now coming to installing the kernel-
*Place your twrp and kernel zip file into your adb folder*
1. Setup usb debugging and connect your device normally to your pc, check if the device is communicating with pc type in "adb devices" and allow on your phone for authorisation.
It should reply with your serial on cmd window.
2. Type in "adb reboot bootloader" that should put your device in download mode.
3. Type in "fastboot boot twrp.img" (replace twrp.img with whatever your twrp image file name is)
4. Go to advanced and select adb sideload, swipe to start.
5. Now move to your cmd window and type in "adb sideload kernel.zip" (replace kernel.zip with whatever your kernel zip file name is)
Wait for the process to finish
Now press home go to wipe>advanced wipe select dalvik cache and swipe to wipe
again press home and select reboot, select system
Now final important step
6. don't swipe, select "do not install twrp"

This might sound like a stupid question but I am a major newbie when it comes to this,
Right now i managed to compile a custom kernel and I have a boot image along with the kernel, so to get the kernel.zip do I just zip up all these files? also I read that I could simply flash the image by rebooting to my bootloader and then using " fastboot flash boot boot.img " would this work , and if so does this mean i don't need twrp...
Thanks again for the help , it is much appreciated

If you just want to flash your custom kernel there's no need to flash a boot.img if you've a running rom installed. You can flash the kernel.zip it via twrp or adb sideload via twrp.
Sorry for the late reply, if you have a bootloader-unlocked 6.1 Plus you should join Nokia 6.1 Plus community on telegram you'll get much faster response from the community regarding your device ?
