So I've been manually entering CWM lately by just holding power and up and then erasing whatever I need erased and then loading up whatever ROM I want to try. For some reason tonight I had the bright idea to run the app and since I Flashed Clockwork Recovery Mode I can't get into the Clockwork recovery mode. It just sits at the Google screen. How do j fix this? I can't do anything. I can't backup my ROM. I can't load am old back up. I can't get into the CWM screen to load at all. WTF?? Please help. This is really annoying.
Sent from my Nexus S using XDA App
1. flash the cwm again,
2. download root explorer (or similar app)
3. go to folder /etc
4. find the file name "install.recovery.sh"
5. rename it with anyname you like (dont delete it)
6. reboot, and try to open cwm again
make sure you remember the file name that you rename before, the file is use to clear custom recovery and back to stock recovery
Reflash it through fastboot and try again
can you fastboot CWM vis bootloader?
Hi,
(newbie question)
I have CWM recovery installed on my galaxy nexus (installed w/o ROM MANAGER). I've successfully created a backup. I've tarred the backup directory and moved to file to my computer.
I know I can restore easily with ROM Manager or booting into CWM but I'm trying to learn things the hard way and want to restore using fastboot.
I've extracted the tar which contains..
boot.img
cache.ext4.tar
data.ext4.tar
nandroid.md5
recovery.img
system.ext4.tar
When doing some googling the process is to sequentally flash all the img files. However the data and system are not packaged as img files but tars.
So what is the process for a complete restore with fastboot?
Eould love to know this as well. I have ADB setup etc but my CWM backup produced .tar files(cache.ext4.tar, data.ext4.tar, syste,.ext4.tar) not .img files (apart from recovery.img and boot.img).
Any help appreciated !
Hi
I have tryed to figure out how to extract data from clockwork backup
I have these backup files:
.android_secure.vfat.dup
boot.img
cache.ext4.dup
data.ext4.dup
nandroid.md5
recovery.img
system.ext4.dup
I have tried unyaffs tool but i only get "broken image file"
So can anybody help me to extract some data (actually only my sms)

Have a look at Nandroid Manager ' ROOT.
Hello all,
I really need, for a commercial project, to flash a great number (>100) of Galaxy Camera 2 (EK-GC200() device, all with the same firmware, rooted and modified as I need.
I have to flash boot.img (modified by me) and system.img (rooted).
I have now to root the camera, then start the system, enable developer options, enable adb debug and at the end flash a new boot.img, and the system.img itself (adb shell, dd ...).
This is time consuming, and error prone.
I'm sure the boot.img & system.img are correct, cause I can flash them without error (and they work fine) with dd from the internal emulated sdcard.
I can see two viable alternatives:
1. A custom recovery, from where I could make a nandroid backup, which I can use later on to update all the rest of the cameras.
But:
I tried to port the EK-GC100 cwm recovery, I've been able to boot it up, but the touchscreen is unusable and I got a lot of error coming from the file system.
Please help me! Any suggestion, half project, everything is really appreciated!
2. To create an Odin package, using the .img files I can optain with dd from a ready camera.
But:
I tried all I can do to build a Odin package, but every time I got an error (Odin Fail) when I try to flash system.img.
I tried to build a package containing recovery.img + boot.img, and that works.
I tried to build a package containing only system.img, and it doesn't work, every time I got a Fail from Odin.
I tried manual compression (tar + md5sum on Linux), and automated scripts you can find on XDA, both under Linux and Windows.
Why is system.img impossible to flash?
What am I missing?
Thank you in advance.
Ciao,
Giovanni
Boot Logo Changer
Change the boot image (NOT the bootanimation) that shows BEFORE the boot animation.
This has only been tested on the T285, but should work on the T280.
If in doubt, check to see if your PARAM partition is mmcblk0p16.
There are programs on the Play Store that can show the partitions, there names and other info.
This app does make a backup of the original PARAM partition and stores it on your /sdcard as PARAM.bak.
MAKE SURE YOUR SDCARD IS MOUNTED WHEN YOU GET INTO TWRP or CWM.
(Have NOT tested in CWM as I have TWRP installed).
Many thanks to [email protected] for the original script for the Samsung Galaxy Tab 3 8.0.
He has kindly allowed me to modify his script for the Tab A (SM-T285).
His xda page is: Samsung Galaxy Tab 3 8.0 Boot Logo
To change the logo (.jpg file), replace the logo.jpg in the tmp folder with your own .jpg file.
Remember the Galaxy TAB A (SM-T285) display is 720x1280.
Steps to install:
- Reboot into recovery
- Select Install from recovery menu
- Select TAB-A-T285-LogoChanger.zip
- Follow recovery install prompts
- Reboot and enjoy!
If you need a restore script, please contact me or post a message.

device soft bricked but can enter download mode (Vol Up + PWR + Home). I did a:
# dd if=/dev/mmcblk0p16 of=/storage/emulated/0/param.lfs
before flashing the custom param. I restored the device using heimdall (GNU/Linux PC)
$ sudo heimdall flash --PARAM param.lfs
device rebooted and worked

Should have no problems with the .zip file. I used on my T285.
It will make a backup of the PARAM block and store it on you internal sdcard before changing the bootlogo.
All that had to be done was replace the logo.jpg file in the zip file (drag and drop). Install it in TWRP.
Obviously, if the logo.jpg file you put into the .zip file is very large, you may end up overwriting something.

the logo.jpg I used is about 600KB in size it may be the problem. What must be the right size so I do not overwrite anything?
I have dumped the partition /dev/block/mmcblk0p16 to a param.lfs
then the param.lfs appears to be a POSIX TAR Archive (GNU) can we just repack the file and modify only the logo.jpg? (the recovery script will repack the tar archive)
after modifying can we just write it with dd?
# dd if=./paramodified.tar of=/dev/block/mmcblk0p16

The original logo.jpg is under 100kb, so a 600kb file would be too big.
I would keep the file under 150kb just to be safe.
Yes, you can use dd to write the modified param file...that is what the logo changer script does.

The script works now, I've reduced the jpeg to 50KB but it is blurry. Thank You
I have uploaded my param.lfs (it is compressed with 7z to reduce size from 2MB to 420KB, 26193062 is a CRC32 hash checksum of the file to verify that it is not corrupt) from mmcblk0p16 that can be flashed with heimdall ($ sudo heimdall flash --PARAM param_26193062.lfs) if someone else messes up.
1. download param_26193062.lfs
2. decompress with 7z (7z x param_26193062.lfs.7z)
3. flash with device ($ sudo heimdall flash --PARAM param_26193062.lfs)

I no longer have a T285. All my T285 files are deleted.
But, my guess is you made the .jpg logo too big.

Now I am using Windows 7 Heimdall to flash this. Except with this I am unable to flash because it's showing "Error: Failed to retrieve config descriptor."
Need help ASAP
Update: After a few tries, now it says
"Initializing Protocol...
Error: Failed to send data!Releasing device interface...
Solution: Used Odin. Basically, using 7zip, packed the param.lfs to a tar file, then packing that to a gzip file, then prooding to flash via ODIN
Any one have stock param.tar file for flashing on sm-t285?? Plz help me? ? ?

You need yo rename your image to: logo.jpg
Then use 7zip or winrar to open bootlogochanger. replace the logo.jpg in the zip file with your logo.jpg
