Fastboot binaries folder?

Hey guys.....
I'm using an Xperia Acro and need a little help in terms of flashing a custom kernel. Please bare with me as I'm pretty new to this.
I'm to upload the DoomKernel, and I *think* I'm ready to go. My phone is rotted, bootloader unlocked, fastboot enabled. Also, I have the necessary files that need to be flashed.
However, I got lost pretty quickly. I'm supposed to put the .img file into the "flashboot binaries folder". I have NO idea what this means. I looked at the systems folders and cant find anything labeled flashboot.
What am I'm supposed to do? Where is this elusive folder?
Appreciate the help...

Anybody? just trying to figure out where to put the boot.img file.....

On your pc you should have a fastboot folder, open that and one of the sub folders should be boot. Place the file there. Shift-right click and select open command window here, enter in the command window fastboot flash boot xxxx.img, xxxx being the bootfile name.

Thanks for the reply. Where would a fastboot folder be on my pc?
Thanks

When you unlocked your bootloader via SE you should have downloaded the SDK files, think it's in there. You'll need the drivers too, there are a few threads on here where people were looking for help with fastboot so you'll find everything there.

I didn't. I had it unlocked remotely by another user on this forum actually......

try these http://min.us/miDhsNng1
I recommend going to the se page about unlocking your bootloader first, it'll give you a link for all the files you need. If you're unsure, create a folder "fastboot", drop the files above in it, any bootfiles just go in the folder beside the dll files, in open folder shift and right-click, create command window, type in window"fastboot flash boot xxxx.img" and see if it asks for drivers

i'll give it a try. thanks!

Says "waiting for device". That mean im good to go?

seems fine, is the blue light on?

Any joy? Can't remember exactly how I set it up, there's a few extra things to download like adb, drivers and such but those files are the fastboot stuff I use. Think you need the Java jre too...

Hey, sorry for the delay. Had to sleep then go to work. Will attempt to do this once i get home!

Hey,
So yeah....it's a no go. I'm not sure if I'm entering fastboot mode correctly, cause the light is green. I hold the back button while plugging in the usb cord.....thats the correct way to enter fastboot mode right?
Anyway, command prompt continues to read, "waiting for device"

Okay, so apparently I needed to be holding the menu key, not the back key to enter fastboot mode.
So, I got the blue light now, but the command prompt still says "waiting for device"

Also, tried opening the fastboot.exe file manually, and it just opens and then shuts down immediately.
So frustrating!

hi mate
most likely ur missing drivers
my set up is fast boot folder inside which is all fast boot files and adb files and I place the .img here ,just in the fast boot folder not a sub folder.
I plug in phone in fast boot then open fast boot folder hold shift and right click on empty part of folder,click open command prompt here then enter "fastboot flash boot boot.img" should flash in 2-3 seconds if all is correct
some times hangs waiting for me if I open command prompt before plugging in phone
hope that helps

Oh sorry man, didn't realise that you were new to this stuff, don't worry.
Basically, flashing boot.img is done on the computer.
1. Open Command Prompt. Start -> type 'cmd' into search area (without quotes)
2. Browse to your folder containing fastboot using cmd prompt. example: your folder located at C:/fastboot so type 'cd C:/fastboot'
3. Flash by typing: 'fastboot flash boot boot.img
4. Erase cache, type 'fastboot erase cache'
5. You're done.
BTW, next time I suggest you read everything properly and know how to do everything before you attempt things like this...

You also need to have your phone connected via usb once you're in fastboot mode to flash the boot.img.
Sent from somewhere....if I could only remember where....

Help!

Hi,
Another amateur here...and will really appreciate your help. I am facing the same problem but after I enter Fastboot, I do not understand how you want me to flash the boot.img file. As of now my phone is on the fastboot screen with the four options mentioned earlier, its connected to the PC (although the PC doesn't show anything) and I am wondering what to do next.
Can you please explain which folder does one have to browse to on the PC? I have no fastboot folder on the PC. All I have is a copy of the zip file of the rom on desktop\android. Do I need to download and install the Android SDK for this??
Really need your help; spend the last five hours looking for a solution but in vain
Regards

Get fastboot files here. Place them in a folder, and this folder will be called the fastboot folder from now on.
Then extract the boot.img from rom.zip to your fastboot folder.
To launch fastboot command prompt, hold shift, and at the same time RIGHT click anywhere in the fastboot folder. Select open command prompt here.
Then do the commands as described by tomascus.

Obviously still a noob!

I'll try and keep this short!
I rooted my one x today. I tried flashing the orio rom with no success.
Luckily I made a backup and am able to restore but I think the kernel is not the stock one I had.
I thought this would be restored as well with the nandroid.
Anyway, I´ve been looking around, and flashed what I believed to be the stock kernel but it just got stuck at the splash screen, so I went back to the tripndroid v006 kernel
I noticed the led flashing red and green when plugged in to my laptops usb. My wifi has error and the phone signal cant connect?
Any help?

You need to flash the boot.img within the nandroid backup.
If you boot into recovery, mount usb storage (under the storage options). This will let you access the internal memory. Look for clockworkmod and find your nandroid backup.
Extract the boot.img and flash that in fastboot.
That should get you back up and running hopefully

Thanks a million mate, I'll give it a go now.

Ok I am using TWRP and there is three files in the nandroid backup, one of them is boot.emmc.win, is that where the boot.img is? How do I extract it?

No need to extract it, just flash it as it is with the same name
Fastboot flash boot boot.emmc.win

What do you mean by that .... Where do you choose the .img file
You have to flash the boot.win file from the pc to the phone that is in the bootloader/fastboot usb mode !

HA, Now you get the thread title? lol I´m using Hasoon2000's toolkit, I boot into bootloader, select flash a kernel,and it opens the browse dialog but only allowing me to select .img type files not .win type files.
Sorry for my lack of knowledge, I realize this is nonsense for most people on here.

Try this then
http://db.tt/ldx3qOOU
Copy these files on the pc
C:\fastboot\files from my link
Then copy the .win boot image to that folder
Now open a command print inside the fastboot folder,right click inside the folder and oke. Cmd prompt then put the phone in bootloader/fastboot usb mode and type the commands to flash the .win file like i said in the earlier post

You made a folder on the pc and if you put your arrow in the folder and right click it .....
Wait my mistake
Hold shift and right click inside the folder it should say something in the list like open commandprompt here . The picture is in dutch .... Hope it makes sense

Haha if that doesn't make sense...
copy your .win file to the fastboot folder and then copy the whole folder to your c:\ drive
Then open Command Prompt. (Win XP: Click start -> run -> type "cmd" ; Win 7: Click start -> type "cmd" ; Win 8: press windows key+Q -> type "cmd")
A black box should appear.
Turn off your phone. Then turn it on by holding volume down and power at the same time. You will be taken to the bootloader screen.
press volume down to highlight "fastboot" -> press power to select.
connect your phone to your computer
Type (without the quotes):
cd c:\fastboot (press enter)
fastboot erase cache (press enter)
fastboot flash boot boot.emmc.win (press enter)
fastboot reboot (press enter)
Your phone will restart and that should be it

Once again, I´m afraid not. I´m using windows xp which appears to not have this option.
I have read in another thread that the boot.emmc.win file I have can be renamed to boot.img and then flashed, what do you think?

CASE CLOSED

[Q] SD card appears empty, and phone is stuck on load screen.

A buddy of mine rooted my phone after I had so much difficulty trying to do it myself. I went to update my ROM this afternoon and was brought to the white HTC loading screen with no more activity. Tried getting into my phone to put a new ROM on the SD card and nothing comes up on the SD card folder. I am able to put a ROM in the empty SD card folder and install it, but than it just gets stuck on the same screen as before. I'm really just in the dark here and that friend isn't any longer available to help me out. Thank you all in advance, hopefully this is fixable. I am quite concerned. I should add that I would like to ultimately just get back to stock and be done with things I don't understand so as to avoid this happening again.

Did you flash the boot.img from the rom.zip? These are the correct steps to flash a ROM:
1. Flash the boot.img from ROM.zip via fastboot. "fastboot flash boot boot.img" then "fastboot erase cache"
2. Boot into recovery and use THIS by flashing it.
3. Now flash the ROM.zip and then gapps.zip via recovery.
4. Reboot.

I have tried flashing the boot.img but when I go to put the file onto my phone I don't have any folders such as the boot.img folder to put it in. As for flashing the link above, I am taking a stab in the dark here but I assume that I download that link, extract it and place it on my SD card somewhere. I'm not sure as to how I flash it. Sorry... I really have tried learning the ropes of this, but I can't seem to grasp it.

I somehow now have access to TWRP on my device... I am so confused.

1. First you need to download a custom ROM like this one : http://tunsd.de/downloads/ICJ/IceColdJelly421/aokp_ICJ422-V3.0.zip , Gapps : http://goo.im/gapps/gapps-jb-20130301-signed.zip and Super wipe script: https://www.dropbox.com/s/0y31poo1kiaif4y/Super wipe script.zip
2. Open the aokp_ICJ422-V3.0.zip with winrar/winzip and extract the boot.img and place it in the "fastboot" folder in your PC. (since you have already unlocked/rooted it, I guess you know which is the fastboot folder)
3. Connect your Phone to your PC and make a new folder named "ROM" and put the aokp_ICJ422-V3.0.zip , gapps-jb-20130301-signed.zip and Super wipe script.zipin it.
4. Turn of your phone. Now hold the power button and volume down button together until the bootloader screen pops up. (White screen with 3 android figures at the bottom)
5. Now select "fastboot" using the volume up/down keys and press power button once you highlight it to get into fastboot. Now connect your phone again to your PC.
6. You will hear a sound on your pc and on the screen it will say "fastboot USB".
7. Now open fastboot folder on your PC and press shift key and simultaneously rightclick and click on "open command prompt here".
8. type the following lines:
fastboot erase cache
fastboot flash boot boot.img
fastboot erase cache
9. Now disconnect your phone and head back to "HBOOT" and then select "Recovery".
10. Now go to "install zip from sd" and select "ROM" folder which you had created earlier on the phone.
11. Now select "super wipe script" and install it. After everything is done you will come back to choose zip from sd.
12. Now again navigate to ROM folder and select "aokp_ICJ422-V3.0.zip" and install it. and then install "gapps-jb-20130301-signed.zip".
13. Now go back and select "reboot system now".
14. If you have done all the above steps correctly, you will boot into IceColdJelly Rom!

Irrespective whether you have CWM or TWRP... Steps will be similar for flashing the ROM... Just the names of the buttons/options will be different!
If you want to use CWM, then download this : http://htcfanboys.com/download/seadersn/?action=list&file=2823
Put the recovery.img in your fastboot folder. Boot your phone in fastboot mode and fire the following lines in CMD.
fastboot erase cache
fastboot flash recovery recovery.img
fastboot erase cache
Now you can follow the steps which I have given blindly!

My phone was unlocked and rooted from a different PC so I have no fastboot folders or any knowledge on what a fastboot folder is.

Hi,
I am trying to install this rom legacy xperia 4.2.2 But I am stuck at flashing kernel
The tool is flashtool as you can see in picture
http://www.uppic.org/share-AA2F_520F170B.html
When I click select kernel to flash, it doesnt do anything and the red text says error...

Don't use flashtool, try using fastboot.exe instead.
Place the kernel in the same directory as fastboot.exe, press shift and right click on the directory and click "open command window here"
Then type they following into cmd:
fastboot devices
Confirm you see at least one device there, it will appear as a jumbled set of numbers and letters followed by the word fastboot. That will be your device.
After that, type this into cmd:
fastboot flash boot boot.img
If done correctly, it will say boot.img sent or something, it will definitely show some kind of success.
You can disconnect your phone now, boot it up and press vol down when you see a blue flash. This will bring you into CWM recovery.
From there, select install zip -> choose from SD card -> ROM zip
Flash it and reboot, you should have CM10.1 running on your phone now.
P.S this should be in Q&A section instead of general.
