[Q] fastboot - no boot or img file - Nexus S General

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

root my dell streak, not shure

Hello, I'm Luis, and i'm newbie here i have bought about 4 months my streak.
Also installed one firewall for some programs don't use 3G connections and only use wifi. that firewall requires root acess.
By your tutorial in here http://forum.xda-developers.com/wiki/Dell_Streak/Flashing_Guide#Rooting_your_phone
and by your tutorial boot recovery mode http://forum.xda-developers.com/wik...g_Guide#Flashing_an_update.zip_with_streakmod
when i press to update from sd card, appears the follwing message:
"Press shutter button to start emergency recovery software"
"Warning: all data will be erase"
"Press volume up to turn off"
What you can tell me about second line "all data will be erase"?
Thanks
I'm betting I know what happened here. After flashing the custom recovery with fastboot, you let your phone reboot didn't you? If you are on a stock rom, flash a custom recovery, and let the phone reboot, the stock rom will rewrite the recovery with the stock recovery.
After flashing the custom recovery, pull the battery. Now replace the battery and power up while holding both volume buttons. When you choose option 2, it will boot into streakmod recovery, where you can flash the superuser.zip file.
Thought I should add:
After rooting, use a root enable file manager (search the market, there are lots of them. I prefer Root Explorer, but it is not free) to delete /system/etc/install-recovery.sh
Now, since you had to boot with your stock rom, your custom recovery is gone. But you can flash it again and it will stay.
hmm, but i never flash it. Its the original rom, only thing i have done, is OTA upgrade to Froyo..
how can i install a costum recovery?
sorry, but e never dit it before..
=== EDIT ===
you mean install StreakMod Recovery, don't you?
thanks
Welk if you havent flashed it, then thats your problem. You have to flash a custom recovery. And yes, I mean Streakmod. Read those tutorials. They will tell you what you need to know.
Sent from my Dell Streak using Tapatalk
Okay, i will try...
sorry, when they say: "Unzip and flash with: fastboot -i 0x413c flash recovery recovery.img"
Its suppose to do this from the phone (but in fastboot, there is olny numbers, no other leters or simbols), so its to do on the computer with usb cable plugged?
What software for flashboot?
thanks
There is a detailed tutorial at http://forum.xda-developers.com/wiki/Dell_Streak
Just go thru it. Make sure you read it again and again.
It is not from mobile. You have to connect your streak to PC. Switch that on by pressing the volume + - button and you get to see the driver installation.
You need to install the drivers first on PC.
Then you need to download the fastboot tools (above link contains all)
Open command prompt from fastboot file location
copy the rom/image (what ever you want to flash) to that location
Do the fastboot
I am not going in to detail as the wiki gives much better instructions !
Read... Read and Read !!!

Help! Can't boot / cant get into recovery. ..

I was unlocked and rooted and ready to install CM7. I followed all the instructions in the Official Atrix CM7 OP to the T, but when it rebooted, I got stuck on the boot screen with "unlocked" and the red M logo.
I tried to repeat the process several times and ended kind of giving up, factory wiping, and then trying to restore my backup. It appeared to restore successfully, but when I rebooted the phone now wont boot at all. I can't even get it into recovery. No combination or order of button presses or battery pulls / usb plugins will turn it on. I just have a green light like it's charging but nothing is working.
Is it possible to brick your phone even after you have been successfully unlocked and rooted just while you are trying to install CM7?
Please help. I am really desperate here. . .

are you using the right recovery? romracer or rom manager!
i am using the tenfar CWM included in the Atrix 4G Automatic Unlock script package. will this not work?
if not, how do I replace it with the right recovery if I cant even get into the phone?

no, that the old recovery you can use the rom manager if you have , or romracer latest recovery you can find that in the development section, also ther was instruction in the cm7 thread.
you should have left it alone at the M boot screen because it takes about 5-10min to boot after unlock and flash...
everything you do now will have to be through fastboot DO NOT SBF FLASH ANYTHING!!!
Go here to use Fastboot
then download the system.img and boot.img from here
use fastboot to push the boot.img and system.img to your phone
if it gets stuck at the M boot screen let it sit for at least 10min
EDIT: get Romracer recovery from here and push that through to your phone through fastboot
Yeah youre going to have to fastboot wipe recovery then fastboot flash recovery recovery.img
Just download rom racers and rename it..recovery.img

Great. Sorry to be such a noob, but do I decompress the CWM-recovery-atrix5.zip file and push the recovery.img file that's inside it? or push the CWM-recovery-atrix5.zip itself?
Also - every time I am able to get my phone into fastboot mode, it says my battery is too weak to flash anything. I cant seem to get the battery to charge enough to execute any fastboot commands. Any way around this? a powered usb hub?

If you can borrow another Atrix user's battery, or take yours to an AT&T store and see if they can charge it for you.
If you're able to get back into recovery then you can just flash the zip.
If not, you'll need to extract the recovery.img to use it with fastboot, or just download it directly from the OP in romracer's thread. (The left hand link is just the .img, the right hand side is the CWM .zip) Then place it in the same directory as fastboot.
So I can literally flash a different recovery from within another?

Its the recovery from tenfar CWM. When I can get it into recovery it seems to be working - with the obvious exception of successfully installing CM7
So I can flash romracer recovery from inside tenfar recovery?
sorry if im being redundant - just dont want to screw it up!
thanks
Just download rom racers cwm. Img, head into fastboot and then fastboot flash recovery recovery-****** (whatever yer recovery image color u chose is)

I was able after a full day of leaving the phone plugged in, to charge it up. Then I flashed the rom racer recovery, rebooted into recovery (new version), installed CM7, installed gapps, and voila! A working CM7 Atrix. thank you soo soo much guys.

The phone stuck in boot screen and overheat, then restart.
In recovery mode is just black screen.
Phone has Neutrino 2.6GT+ ROM whit Clemsyn's OC kernel 1.6GHz and it has unlocked bootloader.
Can I change the kernel without booting in os or recovery?
This problem show after I was extracting very big zip file and phone overheat.

I am actually having this same problem.
My warranty-replacement (unrelated ear-piece failure) had 2.3.6 pre-installed. Thinking little of it, I unlocked the BL and rooted the phone as usual. After this, I tried to install a couple of the ROM's (Neutrino and Morrisoft) which I was most happy with on my previous Atrix.
After flashing either Neutrino or Morrislee's ROM, the phone hung on the M screen. Waiting approximately 30 minutes with no change, I pulled the battery.
When trying to enter recovery mode, the phone would state, "entering recovery mode..." Then go black.
I ended up using RSDLite and sbf flashing the stock 2.3.6 sbf file back to the phone. Then, I had to re-unlock the bootloader and re-root.
This never happened up to, and including 2.3.4, but did twice last night on these ROM's using 2.3.6, and I've flashed many ROM's and Kernels.
It happened to a lesser extent when trying to flash Clemsyn's stock enhanced kernel to the stock ROM, as I was able to enter recovery mode. Entering recovery mode, it would give errors: mounting cache, mounting system errors, and errors to accessing recovery and recovery log files.
Restore recovery would fail in this state, giving me the above errors as well.
Trying to mount the cache and system in recovery would fail. Trying to format cache and system then mounting these could occur temporarily, but would revert back to unmounted when a restore was attempted.
For these problems I pushed a recovery through fastboot.
Just one word: Fastboot. See if Fastboot works and flash everything from there. Or, as Alterna suggested, flash through RSDLite, but that a little dangerous and can brick your phone if you don't know what you are doing. Hope it helps.
Problem sloved!!!

Can't get into recovery mode after changing bootloader

I got an Acer A501 tablet and installed lightspeed 4.8. Everything was working fine but for some reason I decided to update the bootloader to Skrillax_CZ's unlocked bootloader which was recommended. Since updateing the bootloader the tablet randomly reboots itself and shut down. I also can no longer get into recovery mode. I tried using Clockwork mod and also with the volume+- buttons manually but all that happens is it hangs at "booting recovery kernel". Does anyone know how to change the bootloader without entering recovery mode?

1. Make sure you have the Android SDK installed to your PC.
2. Boot the tab to fastboot using PWR and Vol+
you should get a menu
Select Fastboot Mode. Should say it at the top center when in fastboot
3. Download your CWM image file and copy it to your C:\Program Files\Android\Android-sdk\platform-tools folder. (might be in Program Files (x86).
in that folder you will see a file called "fastboot.exe"
Wait, plug your tab in.
4. Open a command window in that folder (shift + right mouse click)
in the window, type fastboot flash recovery nameofyourrecover.img (where nameofyourrecovery is what the recovery image file is named.
5. Hit Enter
Should flash your CWM recovery image back. I advise you use the latest CWM recovery. 1.7.2 or 1.7.3 you can get at tegraowners site

If I don't have a recovery image am I SOL? Can I download one from somewhere?

tegraowners.com is one place.
The other recovery, is PublicRecovery which you can find in the Dev Forum.
Both are good recoveries. Albeit the CWM one is notorious for not revealing source code on his kernels. Non-GPL, which is why he is not allowed to post his kernels or roms at XDA. Might be sending your usernames and login's for all anyone knows,
The CWM "is" GPL compliant. So no needs to worry.
The "search" button, is such an easy thing to use.

Thank you for the help. I found an app in the play store called "Acer Recovery" and used it to flash clockwork recovery. I was able to get into recovery mode after that and install the Tegra Owners ICS rom I wanted to try. I won't forget to do a nandroid backup ever again lol.

Yeah, keep forgetting about that one. But, just make sure the Recovery you installed is a recent one. Not sure how often that app gets updated.
Some of the older versions have issues with ICS sometimes, especially TWRP. So check versions.

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.

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.

Thank you very much for your kind guidance and quick reply. I will perform this may be tomorrow and then inform you. If it is bricked or stucked in any stage/page then is there any instant process to go back to safety?

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.

After typing 'fastboot flash recovery twrp.img' i switch to recovery and select it. But it shows recovery failed,bla bla in red colour. I tried 3 times but same result. What to do? now again when I go to the recovery,i see still it is the stock recovery.

Stuck on "Fastboot Mode" screen

I stupidly tried using franco's app to flash cleanKernel on my rooted phone on 9.0.11, it failed of course and now can't boot my phone. I'm able to fastboot boot twrp.img but I'm not sure what is needed next. I've downloaded the full 9.0.11 ota file thinking something in it (or all of it) needs to be flashed from twrp. Afraid to do anything at this point for fear of losing data. Any tips are appreciated.
I've downloaded mauronofrio's rom-stock-fastboot utility but see he says it will clear data. I'm assuming all the .bat files will do this. Any way to avoid clearing internal storage?

From bootloader screen, using fastboot boot twrp.zip results in OP going to "Fastboot Mode" screen...and staying there. The zip is pushed to the phone but won't boot into TWRP. This started after I stupidly tried using franco's app to flash cleanKernel on my rooted phone. It failed of course and now can't boot my phone. My phone recently updated itself to 9.0.11, fyi.
Any ideas on how to fix this boot issue? Is it just a matter of flashing something from the full ota 9.0.11 file---some img file or something?

Wouldn't you want to be using a twrp.img not .zip?
fastboot boot twrp.img
Boot twrp from the img and then flash the zip once twrp boots?
I was able to recover...thank god. Just used mauronofrio's flash utility. Removed the "-w" flag from the flash-all.bat file and all is good.
Stuck on Fastboot Mode screen once I run fastboot boot twrp.img

Hi, I have just got a OnePlus 6T and I am getting this same error even though I am using the twrp.img - when I run fastboot boot 'twrp.img' it sticks on the Fastboot Mode screen.
I have the .zip on the phone's internal storage along with Magisk ready to install but I can't get there.
I did manage to get into Recovery once in the last 3 hours but under Advanced the only 2 options I have are to reboot to fastloader of reboot to recovery which just takes me round in circles!
Have tried everything I can find/think of right now and am no further down the line
Any help guidance will be greatly recieved as nothing I can find on the threads here seem to help
Thanks

When I think about it, it seems that the twrp.img I am flashing is not taking. When I go into recovery I get to choose 1 of 3 languages, I choose English and then I just get the 2 options as above - thing is, the font, layout etc. make it look like stock recovery and nothing like TWRP I have used before, no TWRP logo etc. Nothing

Ok.. can you get into TWRP? Is so reflash the stock rom.. the once it has flashed do not reboot, go back to install and flash the lastest twrp .zip do not reboot, go back to install and flash/install magisk, once it installs then reboot to system... It will take a bit... Once it reboots check your Magisk manager you may need to reinstall it, reboot to TWRP and reflash it.. reboot to system band you should be good to go...
TWRP isn't there

Thanks and apologies if a two posts appear from me, I submitted one about 20 minutes ago and it isn't showing.
The issue is more than that, even when I try to flash the TWRP image it doesn't seem to take. The phone gets stuck on the 'Fastboot Mode' OnePlus flash screen and hangs there.
I have to hold the power and vol+ keys to get the device to restart and I then receive a message saying 'bootloader unlocked, data insecure etc.' and to press the power to stop the boot process. If I leave it the phone boots into OOS10.3.3.
If I press the power button I can get to recovery mode (albeit there is a password screen there which I have never seen on other devices I've had). I put my password in and choose English. I am then given the two options; reboot to fastboot or reboot to recovery. There is no advanced option to allow me to install TWRP or Magisk zips, as a matter of fact I don't get any TWRP at all, it looks like stock recovery.
Is the phone defaulting to stock recovery and not the TWRP image? That is what, in my very non-expert opinion seems to be happening. Is that possible and if so, any ideas how to fix?
I have completely flashed the phone so it is on stock OOS (10.3.3.) so can start afresh. It is a refurbed 'like new' so could that have anything to do with it?
Thanks for reading the long post - am wondering if there are some other tools I need use to change how it boots?

Ok.. are you using the latest TWRP? If you want in the guide section you can you the msmdow like ad tools to reset you phone to stock, and retry again..
THIS. I have the exact same issue. In short, I have the T-mobile version, and was able to unlock successfully. I am using twrp-3.2.3-0, and I have the img and zip in the same folder, same way Techibee does on Youtube. I then type "fastboot boot twrp-3.2.3-0-fajita.img", I get the "OKAY... OKAY... Booting... Finished" response in console. Then, the Fastboot screen appears and never leaves. I have done this 3 times now. I kept tweaking the process, but I'm nervous to keep debugging.
