No boot or recovery img

last night i flashed an update of clockwork mod through rom manager. i then went to do a back-up of my current rom. the phone re-booted to the fastboot mode and now says no boot or recovery img. when i scroll to recovery and click it, the phone reboots right back into the bootloader. i am trying to flash a new recovery through adb but i cant get anything to connect. when i do "adb devices" in the command prompt i get the daemon started and list of devices but there are no devices listed. "fastboot devices" does nothing either. i have the android sdk loaded onto c:\ and the drivers seem to be installed correctly. when i rooted the phone i used a different pc that i dont have access to now. i also used pdanet for the drivers so i have never had the google drivers set up correctly. i type fastboot flash recovery recovery.img and it says "cannot load recovery.img" i have downloaded the recovery-clockwork3.0.0.5-crespo.img to the "tools" folder and renamed it "recovery.img"
i have tried to explain everything i have done so far but i am sure there are some steps i have missed. i read some on odin and downloaded it but i am even more lost trying to figure that out. i really need some help here and i would appreciate anything i can get

when you're in bootloader, you're supposed to use "fastboot"
you cant flash a recovery using adb.
go into bootloader mode
fastboot devices
... if your device doesn't show up, then your drivers are not properly set up.. uninstall them and look for the sticky and reinstall your drivers using those set of instructions; assure your SDK is updated to support 2.3.X
when you get your device to appear in fastboot devices.
download clockwork recovery 3.0.2.5 (3.0.2.4 is buggy) or 3.0.0.5; 3.0.2.5 is found in dev forums; rename it to recovery.img
put it in /sdk/tools/
fastboot flash recovery recovery.img

i guess i need help getting the device connected through fastboot. i have tried 5 times now to install the drivers verbatim to what the sticky says (using W0lv3r1n3's Great Windows Rooting Guide). adb command works and pulls up the adb help text. fastboot is still unrecognized by the command prompt. adb devices nor fastboot devices works. i have no idea what else to do. most of the stickies just graze over this part and have no trouble shooting guides.

if your device is unable to GET into bootloader mode... that wont get you anywhere.
when you plug your phone into the computer with the USB.. does that USB sound pop up? if it doesnt.. then its bricked.

ok i have fastboot devices seeing the device. but adb devices still wont see it. when i do fastboot flash recovery recovery.img it says cannot load recovery.img. i put the clockwork file in the tools folder renamed at recovery.img. do i leave it as a zip file though?

when i plug the usb in i dont hear a sound. the phone will only boot into "fastboot mode".
when i do fast boot devices i see "38328e03afbf00ec fastboot"

bootloader mode is for fastboot. you wont be using ADB to recover your device.
you unzip the file. it should be like: clockwork-recovery-version..blah blah blah.img
rename it to "recovery.img" assure that your "fastboot" appears as "fastboot.exe" and not just "fastboot." if it is "fastboot" you need to go into folder options and show extensions otherwise you'll be trying to flash "recovery.img.img" and SDK wont recognize it

Make sure you are typing the full file path, for example on my setup its "fastboot flash recovery c:\android\tools\recovery.img"

file extensions are being shown and it is named recovery.img. still saying cannot load "recovery.img" i have tried several recovery downloads from different sources. as for file size of the img its 3,988kb sound right? i tried fastboot oem lock and unlock and everything worked fine. is there another recovery img i can try. maybe a stock recovery or somehting?

ok so i tried "fastboot flash recovery c:\program files (x86)\android\android-sdk\tools\recovery.img" exactly and still nothing i have the path modified in the system so i was under the assumption that i didnt have to write out the whole path in the command prompt.

cd C:\program files (x86)\android-sdk\tools\
fastboot flash recovery recovery.img
is what you want to do.

tried that path and still got nothing. i re-booted my pc thinking that would help and now i cant find my device with fastboot devices. adb isnt recognized either now. i just cant catch a break. although i suppose its my fault. i really appreciate you going back and forth with me like this. with all the trouble i am having does trying odin make any sense? i searched a bit but there dosent seem to be alot of info on that either

Odin is last resort. If fastboot devices shows your phone you will be able to flash recovery. Reinstall phone drivers and get fastboot to work. Then get back to trying to flash recovery. I really think it is some small mistake. Did you exctract the zip of recovery and copy the .img file?
The error you were getting means the appropriate file was not found in the file path you specified, so its not a phone error.

got it. the first line in my command promt kept saying c:\users\dana>. i couldn't delete it so i ignored it and kept typing in the path after that but i guess it was always looking in users/dana and that wasn't where the img file was. i put the img file alone in the users/dana folder and it worked. i guess i am a bit slow to understanding the command prompt. thanks again for everyone's help and patience

My phone booted into Andriod logo with an unlocked, I have successful downloaded
clockwork recovery 3.0.2.5 and rename it to recover.img
I ran following command
fastboot flash recovery recovery.img and it was successful..
I tired to reboot my phone after that as normal but I'm still getting the same screen which only showing the Android Logo with an unlocked lock.
I'm not sure what I am suppose to do after need to get my phone to work again, any help would be appreciated.
Thank you,

[Q] home to root

please dont shout, just take pitty on me.
I have been getting into the world of rooting and have used the HTC Bootloader unlock, and have installed clockwork. i then had a few issues but managed to get some roms working but Im still not fully understanding exactly what im doing.
but i can flash by:
1. Power on'ing and vol down,
2. fastboot - bootloader - loading PG58IMG
3. recovery -wipe data/factory reset - yes
4. install zip from sdcard - chose zip from sdcard - Sensation_3.32.401.5_deodexed - Yes
5. wait for: install from sdcard complete
7. go back - rebootsystem now
Ive tried a few roms, 2 didnt work but this is the 3rd (Sensation_3.32.401.5_deodexed) that has loaded up.
My issue is I dont get how to get my wireless to work. If someone could give simple instructions Id be more than helpfl as all guides i read are too full of jargon. . . . .im not afraid to hit your thanks buttons . . .
Thanks

Hi,
Are you talking about wifi?
Have you got a router?

When you use HTC Dev to unlocj your bootloader it does unlock the Recovery, System, and Boot partitions to allow your device to write to those partitions and not just read rose partitions. But Terri is a catch, if you want to flash a custom recovery you have to use ABD fastoot commands to flash it. When you flash as ROM in a .zip file via Recovery, it only flashes the System partition. You then have to open the dot zip file and extract the boot.img and then use ADB fastboot commands to flash the boot.img to your boot partition. If you do not you will still have the boot.img of the ROM you was using before you flashed te New ROM.
Now let me explain the boot.img a little so you know why it is so important. The boot.img does just watt te name implies, it is what boots the Android ROM on your device. Now let me explain this a little further, the Android OS runs on top of eat is called a Lenox kernel. This means that your bootloader boots the Lenox kernel and the hardware of the device. The Lenox kernel then boots the Android OS. The kernel is also te connection between the hardware and the Android OS. So you see if the kernel is not compatible with the system that is on te system partition you will have troubles like WiFi not working or other I hardware reliant functions. So when you flash a new ROM and you are HTC Dev unlocked you will have to flash the boot.img for te ROM are you will more than likely have troubles.

Malybru, i do have a router but my wifi wont turn on so i cant connect to it.

That is very informative thanks T-Macgnolia. I understand the theorybut i cant work out the process?
How do i get to flash the boot image?
If i go into my rom folder on my pc then try to open the boot file i just get a Windows Disc Image Burner message box asking me to burn to disc.
I used to burn images using virtal drives when making dvds. Will i need to do the same again here with a virtual drive?
Can you break the process down for me?

First you have to download and install the Android SDK. Here is a video by Elite Recognized Developer Adam Outler that shows you how to install the Android SDK. After you have the SDK installed and all the packages are downloaded and installed. Take the boot.img and copy it to the same folder in ADB that has fastboot in it. Now while you are in the folder with fastboot in it hold down the shift key and right click anywhere on the screen and select "open command promt here". This will open a command promt with you already on the right directory. Now boot your Sensation into Hboot by holding the volume down button down while booting your Sensation. when in Hboot select fastboot and connect your Sensation to your computer with your USB cable. Now type the following into the command promt.
Code:
fastboot flash boot boot.img
That is all it is to it. Also the boot.img is a iso file that is why you get that message when you try to open it. You have to use a Android kitchen or another program that can decompile the file if you want to open it and look around.

You sir deserve a big pint of something great. Point by point I:
1. I already had sdk installed so didnt need to install this.
2. I cleared the phone back to factory with Recovery (Power on with holding -Vol, RECOVERY, Wipe data/Factory Reset, Power Off)
3. I went into HBOOT (by powering on holding down -vol)
4. Opened FASTBOOT and connected phone to computer via USB
5. Opened up command prompt on PC (start menu, typed cmd in the search box)
6. I then Typed the following:
7. "cd c:\Android" (to get me into the folder where my files are)
8. "fastboot flash boot boot.img"
9. this then loaded my boot file and bosh, Im done.
I then restarted the phone and bobs your mothers brother Im using wiresless again. Its such an easy process but on the first go it seems like rocket science.
You cant appreciate how greatful i am for your help. Thank you more than a lot.
If i chose a different ROM at what point is it best to do this stage? Are you able to do this to the boot image before you use recovery to 'insatll zip from sd card'? Or do you have to install then come back to it like i did?

For every custom rom you install you need to follow the same procedure.
1. First flash/install the rom via recovery
2. Get the boot.img and flash it via fastboot (some rom's have more than one kernel then choose the best you want)
As long as you stay in HTC unlocked bootloader the above steps are necessary to flash the rom completely to prevent bootloops and wifi errors

Thanks this post helped me a lot!
I got Android Revolution fully working, but I'm trying to flash the newest OC Kernel of SebastianFM over it. But his zip doesn't have a "boot.img", it does however contain the following: mkbootimg, mkbootimg.sh and unpackbootimg. Is it any of those I need to flash, if not, which "boot.img" do I flash then?

Hi,
I believe the boot.img refers to the ROM you are flashing.
This is a kernel.
So,make a nandroid backup,
wipe cache and dalvik,
and flash the kernel from the root of the sd card,choosing install zip from sd card in recovery.

Post 3 in this thread explains exactly where the problem is. But ........you will never unlock that boot partition if ur phone is S-ON. The trick with the wire works...it took me couple of times to do it but it worked. Then.....the lates ViperS version does it for you. You do not have to use ADB or whatever that program was to flash the boot.img It is all in the ROM. I even flashed the newest bricked 1.4 kernel on top.....but that 3rd comment is the key to all problems with Wi-Fi and other kernel issues:fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed:

USB device not recognised on none of my PCs

A week ago I faced this error for the first time but didn't have the time to take a look at it so I just downloaded Air Droid as a temporary solution. But then more problem appeared. The battery indicator wasn't working so I decided to fix it somehow. To dig on Google. I tried flashing different ROMs and recoveries and on and on. the problem is that I'm now stuck on bootloader. I have no system installed and that crappy TWP won't start. The splash screen just flashes and that's all. So my phone is now a brick and I just don't have any more ideas. I need to lock my bootloader somehow so I can take it back to Samsung establish some kind of USB connection so I can install a new atleast,
Any help would be very much appreciated.

Hello,
I assume you are using a windows pc (correct me if i'm wrong)
Use this forum > http://forum.xda-developers.com/showthread.php?t=1901617 to install drivers for your nexus s.
Afterwards, reboot your PC
Do you have adb installed? If so skip this part:
Install minimal adb and fastboot using this forum > http://forum.xda-developers.com/showthread.php?p=42407269
Try inputting fastboot devices into the terminal window and see if your device shows up
Then you can flash everything back to stock. You can do this by following the following steps:
Go to this link and download the appropriate files for your nexus s >https://developers.google.com/android/nexus/images
Use a program such as 7-Zip to open and uncompress the package to a folder of your choosing
Navigate to that folder and try clicking flash-all.bat
Hopefully that will flash your whole phone back to stock. If not you will have to manually flash each part. Do this by typing the following into the terminal, one by one, replacing the file names with the appropriate ones for your nexus s.
fastboot flash bootloader bootloader-crespo-i9020xxlc2.img
fastboot reboot-bootloader
fastboot flash radio radio-crespo-i9020xxki1.img
fastboot reboot-bootloader
fastboot -w update image-soju-jzo54k.zip
For example, for the first line of code, I would go into the uncompressed folder and hold down shift while right clicking the bootloader file. I would then select “copy as path”. Then I would go back to the terminal and type “fastboot flash bootloader ” then paste the path I just copied. I would then repeat for the rest of the items.
Feel free to ask questions if it does not work. Ill try to reply as soon as possible. Cheers.

Thanks I solved it. The problem was with my phone's USB port. Atleast the usb module/part of the port. I put a little metal in it then moved it around a couple times.. tried to save it. Somehow I got it working again, so I instantly flash a working recovery then went back stock. I returned my device to Samsung (It was under warranty) and they fixed it.
Cheers

Flashed stock recovery and thought I soft bricked my shield tablet.

First I'll give credit where it is due. From two threads on this site is where I got help with this issue:
I followed THIS guys steps for manually erasing and got the recovery images and lots of other useful information from HERE. Thank you guys very much!
OK, so, hopefully I can help someone with my little story as well. I was having issues with apps and programs crashing on me with lollipop and the new marshmallow update. The tablet just wasn't working properly and moving slow. I even had the SD card holding all my apps and larger files so I didn't overload the internal storage. So, I decided I wanted to flash back to factory/stock recovery and go from there. I did this using THIS method. I flashed via the "flash-all.bat" file (the command in fastboot is the same as the file name). I should note that there was one instance that failed during the install (I did try it again and got the same failure). Said something about “did you mean you wanted to flash this partition” or something, then showed it failed. After flashing I hit continue on the bootloader screen of the tablet and it said it was "cold booting." After about 5 minutes or so it started to boot but never made it past the NVidia screen. I tried wiping the phone with factory reset, wiping the cache, etc. and then re-flashing the recovery (again with the .bat file). I tried flashing TWRP but it didn't install apparently, because it still went to factory recovery. I even re-locked and then unlocked my bootloader to see if that would set everything straight. Nothing seemed to work. I knew I would eventually find a solution though so I kept looking. Stumbled on some other people that had the same issues but no solution (hope those people got it figured out). So here's what I did after some more research:
First, if you're in this situation and you did factory reset to try and resolve the problem, you may feel like you can no longer communicate with the device via fastboot/adb, but as long as you have the usb drive and your SDK tools installed (I used CodeWorks for Android all-in-one program) that shouldn't be a problem. You'll just have to be in the bootloader on the tablet.
-If for some reason you deleted or uninstalled your drivers and tools you'll have to download them again and then, the computer should still be able to communicate with the tablet. In the device manager under portable devices it will still show up as Module something or other. So the computer still sees the device but doesn't fully recognize it yet. Don't worry, this should still work! Just make sure you that fastboot is seeing the device by inputting "fastboot devices" in the command window and a 14 digit serial number should pop up. If it just says "list of devices" or there's nothing then you wont be communicating with the tablet.
Your device should be connected to your computer and started in bootloader mode. On your computer you should have the command prompt for adb/fastboot open. I just go to the folder where the .exe files are located and hold shift and right click in the white space of the folder, then select "open command window here."
From here follow the erase steps: stolen from manigault! :highfive:
fastboot erase system
fastboot erase userdata
fastboot erase boot
fastboot erase recovery
fastboot erase cache
Then flash your recovery MANUALLY:
fastboot flash recovery {dir}/recovery.img
fastboot flash boot {dir}/boot.img
fastboot flash system {dir}/system.img
fastboot flash userdata {dir}/userdata.img
fastboot flash staging {dir}/blob
fastboot flash dtb {dir}/tegra124-tn8-p1761-1270-a04-e-battery.dtb
You can download whatever recovery version you wish. I downloaded 2.2.2 because that's what my device came with out of the box on Christmas 2014. It will more then likely be a .zip file. To make this whole process a little easier simply extract the files in the .zip file where the adb.exe and fastboot.exe files are located (folder should be named platform-tools) and you can completely eliminate typing the whole directory before the file name. ***After your done flashing everything you can go back and delete those files if you want. Just double check that you're deleting the right files by looking at the original zip file. Not sure if it makes a difference but I deleted them anyway.
For example the commands in fastboot will look like this exactly :
(after extracting recovery files into platform-tools folder)
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb
Note: Do NOT use the flash-all.bat command as this doesn't seem to work for this situation. Do it manually like shown above. And let each individual process complete before attempting to input another command.
After this step I didn't select continue on the bootloader. You can either select reboot or simply input "fastboot reboot" into the command window. It may take about 5 minutes to start installing everything but just be patient, it should start. Sometimes with these things you have to do things twice before it works. If for some reason it doesn't work the first time then start from the beginning and try it again. It took two times for me, but that's because I installed system.img twice and was getting double screen. Newb error... and I was a bit inebriated last night when I did this.
Hope this helps someone!
Thanks again to manigault and MidgetMob!
NVIDIA download files HERE!

i think i done the same thing
but the problem i now have is i cnt get tablet into fastboot on pc. i can load fastboot on tablet with power and volume down , but the tablet only shows as MTP device in device manager. i have downloaded drivers from nvidia and no matter what i try i cant install them i have been through all instructions but scince it went to mtp device i cant get device showing in adb. The only way i can get device showing in adb on pc ist to select apply update from adb ! but none of these commands listed in your post will work because its in sideload. is there anyway i cn reset , flash custom rom ect bu using commands while device is in adb sideload.
all i get is now send the package you want to apply to the device with "adb sideload <filename>".....
if you could shed any light on this it would be much appreciated , thanks , lester

did you update official android 6.0 before? then, not working stock recovery, stock boot...
If you can enter bootloader mode, download unofficial twrp 3.0.0.0 (here http://forum.xda-developers.com/shield-tablet/development/wip-twrp-2-8-0-1-unofficial-t2877117) and flash it.
i have a working boot.img file on marshmallow if you want.. please reply.

Sorry for the late response! I have no clue how you got into sideload??? Are you talking about through the recovery on your device? You're not able to get adb/ fastboot to recognize the device, right? It doesn't matter how you get the tablet into the bootloader. Whenever you have the phone in the bootloader then you'll use the fastboot command to "talk to" the device; i.e. "fastboot devices" without the quotes. That command should show your device if it shows as an MTP device whenever you open your "device manager" in windows. That's the same exact situation I was in. Download the codeworks from nvidia like I linked above. Hopefully then you should be able to recognize your device through the bootloader. If not DM me and I'll try to help you.

I'm having the exact problem as Lester. Tablet boots into bootloader but won't connect to computer. So I go into recovery mode and nothing works except apply update from adb. Which brings up the side load message that Lester quoted. And bootloader is showing "device=locked". I am attempting to fix this tablet for a friend that messed it up trying to flash a custom rom. Problem is he had no idea what he was doing and I'm not exactly sure what he did. I do however have a lot of experience with rooted android devices and flashing so any help would be GREATLY APPRECIATED!

Also, I've already tried flashing stock rom back onto the tablet by applying update from sd card function in the recovery but when I try to do that the tablet for some reason can't mount the sd card.

If you've got the device in bootloader then you need to use fastboot, not adb. Try the command 'fastboot devices' and see if the device id is listed. If so then grab a factory image, unzip it and use fastboot to flash the .img files using the commands 'fastboot flash system system.img'. Just make sure to match the partition names to the files.

Hello i have similar issue except when i try flash something i get this error ''remote: file write failed''
and i have to reboot into fastboot to get it flashing fully
but even though i managed to flash everything by rebooting when i boot system nothing shows up, i can just see the back light coming on and turning off after a while
Please help

erased os on mi mux 2s

Hi ppl. I need help bad! I accidentally erased my os. So when I try to flash a rom using the mi flash tool(which is amazing) it won't work because I have no operating system to enable USB debugging.so it says enable USB debugging but I can't. Any help would be appreciated TW RP installed unlock bootloader. Thanks in advance!!

just flash recovery rom using twrp then.

Way ahead of you..I tried to transfer several times,files,etc from my PC for some reason two stops halfway and doesn't copy them or move them. Only thing I haven't tried it is ADB sideload.. for some reason that never seems to work for me or work out the way I wanted to.

So twrp is flashed? Then yes try sideload. Also make sure your ADB is up to date as I've had that cause issues with large files and sideload before.

Miflash doesn't need for usb debugging to flash rom I believe. It's all fastboot. If ur phone is not detected by pc, it means drivers.

It does indicate USB debuging not on. So yes it does . I've used it before to flash TWRP. The flash will also install the drivers before you use it so I can understand why it won't let me transfer anything from PC to phone when fastboot mode. It won't let me get past that stuff in this USB debugging is enabled. Frustrating brand new phone to only a couple weeks old.

Have you booted to twrp and format data (the one where you have to type "yes")?
Mi flash only required adb because it needs to run adb reboot fastboot. I'm in the States as well, PM me and maybe we can get this guy working over remote support. I haven't seen this issue myself, so I can't comment much.

Its all good. I'm about to pick up my kids from school, so let me head home, I'll PM you in a bit. We can use TeamViewer or something. If it comes down to it, I also have my work login to use for remote assist. You just need a semi up to date laptop or desktop computer.
Hopefully we can get this solved quickly. I'm unfortunately not in your immediate area, otherwise much easier hands on. The company I work for is down the street from your location however, I'm just a remote systems guy.

Only thing is for some reason I can't transfer anything for my PC to TW RP or my internal storage some reason just doesn't accept it and it's not my computer

I had the exact issue two days ago and the only thing that worked was to manually flash to stock. Since you already have the fastboot rom downloaded and extracted the hard work is done. What you need to do is to put all the files from that main folder (images) into a folder that you have adb installed. Then with your phone connected in fastboot open up a command prompt and once you have the directory set to where your fastboot is type the following and wait until each is done and says okay to move on.
fastboot flash modem modem.img
fastboot flash tz tz.img (I can't remember if this one actually flashed. I think it failed but it didn't matter)
fastboot flash logo logo.img
fastboot flash recovery recovery.img
fastboot flash system system.img (this one will take a long time to start flashing, don't worry. Also, there are about 5 files it will flash so be patient)
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
fastboot reboot
That puts you back to stock. I spent almost a whole night freaking out because I didn't have an OS and I couldn't get TWRP to reinstall. Once I did that and got things going I downloaded the same versions update on the phone (the one that can be flashed through the update page in settings) and did a flash of that as well.

The OP's issue was solved by just flashing TWRP, booting to it and sideloading the Stock ROM. I had the OP download the fastboot files as well, but we ended up not needing them.
