[GUIDE] Flash any recovery easily on the phone using flash_image

Background
To update (flash) a recovery image onto your phone allows you to update or replace your recovery environment on your phone. There are a number of ways to flash a new recovery image, some of the more commonly used methods are using a tool such as ROM Manager or using development tools such as Fastboot. There is also a third method using a standalone utility "flash_image" which allows the flashing of recovery using the terminal emulator on the phone.
flash_image is not a new tool, it has been used on Android since the beginning, many custom ROMs include the utility as part of the ROM itself though not all stock ROMs (including the stock ROM on the G2) include it.
Requirements
1. A permanently rooted (with S-OFF) phone
2. The flash_image binary
3, A recovery image that is compatible with your phone and ROM
3. A terminal emulator application on the phone or use of an ADB shell
Overview:
1. Get the flash_image binary and recovery image onto your phone
2. Copy or move the flash image binary to your system and make executable
3. Use flash_image to update your recovery environment
Stage 1: Get flash_image and recovery image on your phone
1. Download the flash_image binary (not needed if you are running a custom ROM that includes this binary)
2. Download the recovery image you wish to use
You can either directly download the files onto your phone or onto your PC and transfer to your phone. Probably the easiest way to do this is to connect your phone to your computer via USB and mount USB storage, then copy the files to your SD Card. Alternatively you can use ADB Push, bluetooth file transfer or several other methods.
Stage 2: Copy or move the flash image binary to your system and make executable
In terminal emulator:
su
mount -o remount, rw /system
cd /sdcard (or wherever you downloaded/copied the file)
cp flash_image /system/bin
cd /system/bin
chmod 777 flash_image
Click to expand...
Click to collapse
Stage 3: use flash_image to update your recovery environment
In terminal emulator:
su (not needed if using the same terminal session used in the steps above)
cd /sdcard (or wherever you downloaded/copied the recovery image)
flash_image recovery recovery.img (use the appropriate file name for the image file you are flashing)
Click to expand...
Click to collapse
Reboot into recovery and verify that the correct recovery environment is installed
Notes
Any of the commands that call for using a terminal emulator on the phone should work fine using an ADB shell if you prefer.
This was tested on G2 but I can't think of why it would not work on Desire Z or any other phone for which this version of flash_image works. Obviously different phones have different compatible recovery images.
I've attached a zip file containing the flash_image binary that I extracted from the CM 6.1 update zip. I suspect most custom ROMs already have flash_image.
If you are wondering "Why should I use this method over using ROM Manager?" you could be using a recovery image that ROM manager doesn't support, for example ClockWorkMod Recovery 3.x which is required for some experimental ROMs.
If you are wondering "Why should I use this method over using fastboot?" The two main reasons are you can't use fastboot if you are not with a computer with working ADB and using fastboot requires that you have previously flashed the engineering HBOOT.
This is my first guide so I'm open to suggestions or feedback.

Nice one
Though I would suggest that
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
could be simplified to :
Code:
mount -o remount,rw /system
Edit - actually /system isn't even on /dev/block/mtdblock3, and it's not a yaffs2 file system, I suspect that's come from another phone model ?

"dd" will do exactly the same, but no need to install extra stuff since its already there.

I wouldn't have a problem using dd myself. But I would have thought it was much more risky, since instead of typing something relatively user-friendly like "recovery", you're typing in /dev/xyz/abc or similar, which if you get it slightly wrong could be disastrous ?

Excellent, worked for me, flashed CW 3.0 without fastboot

Interesting, I've been using that command since forever (since I first rooted my G1 in early 2009) and it definitely does work on my G2 as well as my wife's MT4G.
I just tried "mount -o remount,rw /system" on my phone and it does not work, mount gives me the "Usage:" messages which seems to mean it wants more parameters.

Unless you run wpthis before dd, you're perfectly safe. The radio partitions are all protected by the power-on write protect feature of the eMMC AS WELL as the linux kernel write protect on low addresses. Worst you can do is blow away your system, data, cache, misc, boot, or recovery partitions, and these are trivial to recover from.

Depends on whether or not the mount command can tell the associations between the devices and mount points, which is determined by either system configuration, or what mount command you are using (i.e. android's mount or busybox mount).

Sorry, there should have been an extra space, this works on my phone :
Code:
mount -o remount, rw /system
I don't have a "/dev/block/mtdblock3" on my system. My system partition is mounted on /dev/block/mmcblk0p25, and it is ext3 not yaffs2.
What ROM are you running ? I am running the stock DZ 1.34 ROM. I wonder if you are running Gingerbread ?

I'm running the Stock G2 T-Mobile post-OTA ROM, definitely not Gingerbread.
Edit: I just tried your method and it works, I will update the guide because your way is simpler and sounds like a safer choice.

you could just rename the CW 3.x.x recovery to the exact named recovery slap it in the cloclwork download folder after you delete the old one and flash it with CW just a quicker trick for GB roms

Not sure that's actually quicker, at least I don't think it would be for me, especially if you are changing recoveries with any frequency (like if tying out Gingerbread ROMs then going back to a 2.2 ROM) because you'd need to constantly rename your recovery images. With my method you would only need to leave the two files named as they are, or for expediency you could rename to recovery.img and recovery3.img then when you wanted to switch you could just execute:
flash_image recovery recovery.img
Click to expand...
Click to collapse
or
flash_image recovery recovery3.img
Click to expand...
Click to collapse
Depending on which recovery you wanted at that point & time.
As I said in the guide, there are already a number of options available, using ROM Manager and fastboot are the most commonly seen in guides but your method and mine are other options for people for whom they work better.

Works!!!
Hi my friends!
It worked for me flawlessly. I was using virtuos 0.9 on my desireZ

Great description, but file did not work for me
It's a very good description that a novice like me can follow. And, I am sure the provided file works for many of you, since many of you reported it to work. After following this guide, and not getting it to work (Stopping Signal error), I decided to find another binary file for flash_image, and the other flash_image file worked for me on my Sprint CDMA Hero. My phone currently has aospMod v0.9.9.2 | AOSP 2.2.1(12/10/2010), if it matters.
One can download a flash_image from here http://cyanogen-files.carneeki.net/flash_image.zip
Then unzip and place on sdcard - follow all the steps in the original post of this thread.
It is my understanding that this file is not unique for different android phones, but if I am incorrect, someone please reply to this thread to correct me.
Again, great job in summarizing the steps.
Regards,
Sanjiv

so darn easy! thank you!

Also usable for splash screen ??
Just curious,
Anybody tried to use flash_image to flash a custom splash screen ?
Something like :
flash_image splash1 customsplash.img

very good post for a newbie like me, just want to make sure, do i need to do the stage 2 every time I flash the recovery?

No, you only need to do stage 2 once, whenever you update/change recoveries from that point forward just use stage 3.

Is there a way I can reflash a recovery without access to the ROM?
I'm stuck at the HTC splash screen, so I'm basically stuck in my current (broken) recovery.

The flash_image in the start post did not work for me, the one above did.
Also, my HTC Hero was missing the cp command.
Instead, I used: cat /sdcard/flash_image > /system/bin/flash_image
Successfully flashed recovery again

System Partition Missing

My Galaxy Nexus system partition appears to be missing Is there anyway to recreate it?
Thanks

What makes you think it's missing? What you were doing to your phone when this happened? Got Nandroid backup? More details, please..

When I attempt to mount it CWM states that it is unable to mount and when you run the log it states that the volume does not exist.
I was attempting to install Bugless Beast from Rom Manager download and it looked to me that it was successful and I rebooted and I was stuck at the Google lock screen. I have a android backup but when I attempt to restore it CWM states that it is unable to mount and erase /system which is what leads me to believe its missing.

Have you tried to flash one of factory images? Which version of GN you have? GSM/CDMA?

Yeah I have tried all the images. I have a CDMA model.

Sorry, i'll give up here. Perhaps someone else can help you.
PS. Just a thought. What if you could find .PIT file and and flash factory images from ODIN with "Re-Partition" option ticked?
Just be warned, on SGSII forums i've seen few people crying about bricked phones after doing so.

Boot int CWM, connect the phone to your PC, then open a command prompt and run the following adb commands and post the results here.
Code:
adb shell ls -l /dev/block/mmcblk0*
adb shell dd if=/dev/block/mmcblk0p10 count=5

Data Recovery without screen

Last night my phone fell out of my pocket while doing chest press with dumbbells without me noticing. Of course when I dropped the weights, they could not have landed anywhere else but on top of my phone.
So Ive contacted samsung and I'm ready to ship it over to them for repair, but I would like to gather the images and some unsaved numbers off of it if at all possible. Is there anyway to do this without the screen? There is a password to unlock the device and im not sure if I have USB debugging on or off. Im pretty sure it prompts me if I want to use it as a usb drive still. Any help is much appreciated.
THanks

Yes, there is a way. That is if you can access adb!

If you have USB debugging on, you can fire up the command line and use an "adb pull /sdcard/".

If you can't get a dB you could probably use an mhl adapter to see the screen.

You if you have an unlocked bootloader, you could always run a nandroid. Then you could pull it off your device with the previously mentioned command: adb pull /sdcard/

Could I unlock the bootloader using the galaxy nexus tool kit without the screen?

You could, but that would defeat the purpose, as unlocking the bootloader wipes the device...

I think I might be screwed then. When ever I used the tool kit it just hangs at " Waiting for Fastboot"

What are you trying to do with the toolkit? (It's better to do things through the command prompt yourself. You will see where things go wrong, if they do.)
If it says "waiting for fastboot", I would guess that the toolkit is trying to do something in fastboot mode and either a) your device is not booted in fastboot mode, or b) your fastboot driver is not installed on your PC.

i was trying to do a media card recovery.

Data Recovery - Galaxy Nexus
Do you have a suggestion for how to image the drive? We are working with a Galaxy Nexus mobile phone that has an internal drive only (no removable sd card). When plugged with a USB cable, the phone is detected as either a Camera or Other Device even in USB debugging. I was able to pull the system files doing Fastboot pull/system but have not been able to pull the remaining partition. Do you have any tips for copying this image?

Are you rooted? If so in terminal u can dd / each partition to the sdcard then pull them from the sdcard to pc
if you are rooted already you can get a little advernturse if you absolutely need the info from the device
install android sdk,
us cmd or termail enter shell
dd if=/dev/block/mmcblk1p11 of=/sdcard/boot.img
dd if=/dev/block/mmcblk1p12 of=/sdcard/recovery.img
dd if=/dev/block/mmcblk1p17 of=/sdcard/system.img
replace the mmcblXXX with that of your device ( google will help u find it)
the just pull the imgs from deivce
this may work below
/sdcard vfat /dev/block/sda1
/system ext4 /dev/block/platform/omap/omap_hsmmc.0/by-name/system
/cache ext4 /dev/block/platform/omap/omap_hsmmc.0/by-name/cache
/data ext4 /dev/block/platform/omap/omap_hsmmc.0/by-name/userdata

/xloader emmc /dev/block/platform/omap/omap_hsmmc.0/by-name/xloader
/radio emmc /dev/block/platform/omap/omap_hsmmc.0/by-name/radio
if you MUST see the screen u can always screencast it to your pc. or mhl adapter
althought screen cast is free and works with nexus ( refresh rate is really bad but will get the job done) also be creative, connect a mouse to your device and that plus screencast all good man,

Sorry, I thought I saw userdata in your post above. Anyway, I would have figured that all he wanted would be the userdata partition, given that everything else is pretty much readily available, no?
This should get the entire userdata partition for him:

[Quick Fix] Guide to corrupted /efs partition.

For Sprint Samsung Galaxy Note II SPH-L900
Click to expand...
Click to collapse
Anything you do to your device is under your discretion, I won't be held responsible for what ever happens there of.
This quick fix was found in my attempt to fix my brothers Note II.
What you need:
Odin v3.0.7 - Must know the basics
TWRP Latest for Sprint SPH-L900 - ( To use builtin Terminal Command mode )
Go to https //goo.im/devs/OpenRecovery/t0ltespr/ < add : to go to the link, make sure you get the latest version.
Boot into download mode and open Odin, click PDA and flash TWRP.
Boot into TWRP Recovery select Advanced, then Terminal Command, it'll ask for the main directory to use default is '/' leave it there and hit select.
To find the mount point for /efs type in this command: cat /etc/fstab
Look for /efs and the mount point will be to the left of it, ours was: /dev/block/mmcblk0p3 ( the l is L )
Now what is needed to be done is a simple command to recreate the ext4 filesystem, make_ext4fs /dev/block/mmcblk0p3
If you need to check if it works is by mounting your /efs folder with: mount -f ext4 /efs
No error should be displayed and the folder should be mounted, lets unmount: umount /efs
Reboot back to download mode use your stock firmware for your SPH-L900 let it go through and you should have a bootable /efs, so stock will restore it.
Any other questions just send me a PM

Actually if you have the aroma file manager you can use any recovery. There is a terminal built into it. Also you can flash any recovery through your current recovery if you already have a custom recovery installed. Well enough of the bs. Thanks for posting your fix. I am sure it will help others fix this same issue.
Sent from my SPH-L900 using XDA Premium 4 mobile app

Yeah but in our case we could only go into download mode and recovery. It wouldn't boot past the Samsung logo because the efs wouldn't mount. It took a couple hours to get it done but this is what worked "quick fix" is what worked on my device.

Bricked AFTV1 - Is repair possible with hardware mod?

I feel like a bonehead cuz I bricked my FireTV by getting ahead of myself. This FTV came shipped with 51.1.3.0 and I have always had updates blocked in my router. I purchased a SD-card adapter and was able to gain root by injecting su into /system/xbin, Installed busybox, and all that fun stuff. Everything was going along just fine, until i tried to install RBox's boot menu/Recovery without fully understanding everything. Following a guide, I ran the full bootloader unlock script and it seemed to complete fine and FTV would still boot normally with root access. What I did next is the following, trying to install recovery I download the bootmenu.img file, uploaded it to my sd card and issued the following commands:
mount -o remount,rw /system
mkdir /system/boot
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=/system/boot/boot.img
mount -o remount,ro /system
dd if=/sdcard/bootmenu.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
exit
exit
adb reboot​My FTV restarted and has been stuck at the FireTV Logo every since. Not exactly sure where I went wrong. Did I have to downgrade before trying to install the boot menu? I did to the checksum test on the file before using it and it matched. Anyways, I tried factory reseting by holding the back/right remote control keys....no joy, tried the alt+prtsc+i keyboard procedure....nothing, tried a fastboot cable recovery.......got the drivers installed, firetv listed in devices using kindle usb driver, but although fastboot would connect and communicate to the FTV, it wouldn't respond to any fastboot commands.
I have the ability to gain direct access to the FTV's file system, but although my electronic skills are superb, my linux/android skills are quite lacking. When I disable the CPU and connect the flash to my Ubuntu 15 VMWare system via usb, I am able to mount up 6 linux partitions from the FTV. I explored around them, but don't want to go plowing through anything like a bull in a china shop until I have a direction to take from someone who actually knows what they are doing to get my beloved Firetv booting again. Any suggestions would be GREATLY appreciated. Thanks in advance.

Plug in the fire TV with a USB to USB to your PC. If the boot loader is fully unlocked you should be able to fastboot boot clockwork recovery and flash the rom that doesn't require boot menu.

I mentioned in my OP that I have already tried this and although the fastboot drivers install correctly, the "fastboot devices" command returns nothing, and the "fastboot reboot recovery" command waits for about 10 seconds, then returns "no reply received by device". So this is a dead end and I guess the problem lies in the fact that my bootloader failed to unlock. I was also guessing that the solution would be to put the stock bootloader back onto the FireTV, but cannot figure out where it goes on the fire's 6 mounted partitions in linux using the soldered-in USB flash device. I can access the /system directory, but cannot locate the /dev/block/platform/msm_sdcc.1/by-name/boot folder where the bootmenu.img file was written to which caused the bricking. Any other ideas?

No I'm not that familiar with the partitions. @rbox would probably be the best one to answer this

Thank you for chiming in Rbox. I am in awe of your amazing work with FireTV and keep up the spectacular work!!!
Anyways, I wanted to attach a screenshot of my dead fireTV1's MMC partition layout, but becasue I am new here, the forum won't let me add a screenshot jpg. I used gparted because as I said before, I am a linux novice and couldn't get gdisk to show me what I wanted to. Partition 10 is labeled "boot", is 10MB in size, and shows up as having a file system type "Unknown". Should I dd the stock recovery file to this partition, or what do I need to do to undo these commands which bricked my device. (Which I am pretty sure due to the fact that I didn't get the bootloader unlocked correctly).
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=/system/boot/boot.img

You can just dd that boot.img in /system/boot back to the partition to undo what you did.

That did the trick & my FTV is now booting and still has root and all my stuff just where I left it......you are the best!
Should I not even try to install boot menu/recovery? I thought i was on 51.1.3.0, but I just now checked and I am actually on 51.1.4.0. I ran the full bootloader unlock script right before I reflashed the recovery partition which bricked my fire. Is it because 51.1.40 is the version-of-no-return for installing recovery, should I have ran the partial bootloader unlock, or something else? Any advice? I am happy to have my Fire TV working again, but half the fun of this is learning and understanding what goes on inside and how it works. THANKS AGAIN!!!!!

You can't unlock that version. You should block updates and wait until I release TWRP and prerooted fireos5 roms.

hey rbox, quick question: once you release the prerooted fireos5 is it possible to dd recovey.img through hardware mmc to get the unlocked bootloader?
my firetv got bricked using supersu me and now i wonder what the best way is to bring it back alive..

Can you tell me the command wich give you finally the success ?
Another question by me is how to create a system.img from the bin files.
I know that there is folder in the bin-zip but how to create from them a system.img or how to create a valid stuck-recovery.img

Certainly. The process I went through (using Ubuntu Linux 15 with Fire's eMMC chip connected via USB via hardware mod) is as follows (keep in mind I'm not a Linux genius but know enough to get by:
When eMMC is successfully connected, Ubuntu auto-mounted 6 partitions with partition names/ids that consisted of a long string of hex digits.
By looking around these ext4 partitions, I noticed that one of them was obviously the entire contents of the Fire's /system folder.
I navigated to /system/boot/ and saw that the boot.img file was in there. I right clicked on it, selected Properties to gain a full path of the files location and copied it
I installed and ran gparted partition editor to view the partition layout of the eMMC. There are a total of 20 partitions on fire's disk, (/dev/sdb1 through /dev/sdb20 on my system) but most of them aren't mounted because they use a non-linux standard file format).and as Rbox said. Partition 10 was 10.00MB in size, type=unknown, name=boot, and was located at /dev/sdb10 (on my system).
Now all I had to do was issue this command: sudo dd if=/<long string of hex digits described abouve>/system/boot/boot.img of=/dev/sdb10
Remove 4 wires soldered to Firetv, Solder CPU oscillator pads together, Reboot and Cheer​The fire tv rebooted fine and everything was good....but I do have an update with even more good news. I felt emboldened having access to my MMC ao since my software was on version 51.1.40, I was able to then follow the guide (EXACTLY) at http://solderwiresandplastic.com/20...the-amazon-firetv-to-achieve-root-privileges/​starting at "Step 2", and was able to successfully install the latest clockworkmod recovery, RBox's AWESOME boot menu, and install RBox's latest prerooted rom. This worked because I was on version 51.1.4.0 and the bootloader eFuse freeze occurred on 51.1.4.1 (so don't even think of trying the steps in this link if your box has 51.1.4.1 or higher on it. Hope this makes sense and helps in some way.

No. To unlock your bootloader you need an old version of the aboot partition. But if you're on the latest software, you will brick if you attempt to flash that old version.

thanks, good to know!

Hello. I have a bricked fire tv because of supersu me. I've extracted a system.img from a working one via adb. My problem is, that i don't know how to install this on my bricked one with hardware mod (card reader). Any advice?
