[Q] What size system.img - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hello,
I followed the tutorial from xda on how to preroot a firmware, but i'm stuck on the step that i have to re compile it to a firmware file.
I don't know what size i've have to fill in for my system.img.
Where or how can i find the exact size that i've to fill in???
Not only for the tab3 7.0 but in general because i've planned to do more devices??
Greetz,
Mark

Because i also have a S3 and i want to root a acer tablet, therefore i need to know how to get the size for different devices..

Look at the size of the stock system.img and make it just a little bigger. My stock image was 1153 mbs, so I used 1200.

Yes, or you could use a archive viewer like 7zip to look at what size the system.img is.
It just tells the script what size the .img file needs to be.

Oke thanks just checked it, the system.img in the tar is 1.1Gb, so 1200 is a little bid bigger..
Following the manual from beginning to end now..
Hoping to have a prerooted firmware for my tab3 7.0 Dutch in a hour..

Dawm i've followed the hole tutorial but when i try to add the md5sum, i get:
bash: prerooted.tar: permission denied
even when i try to do:
sudo md5sum -t prerooted.tar >> prerooted.tar
What is going wrong and what can i do to make it work????

Check the folder and file permssions to make sure you have the permissions to modify the file. I'm not a linux expert at all, so that may not be the issue. Did you log in to linux as "root" user, or as your normal account?

I'm also not a expert, but with the sudo command, the command is executed as root.
I checked the permissions and it is set to root, so i presume that it is correct...

Mounting a .RFS file in OSX

In case anyone wants to mount one of the .RFS files out of a firmware image (in particular, the "hidden.rfs" in the full 550MB+ CPW firmware which contains the full version of NovaHD) from within OS X, you can do so via these commands;
sudo mkdir /Volumes/RFS
sudo hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount filename.rfs
Take note of the drive number the command returns, then,
sudo mount_msdos /dev/diskX /Volumes/RFS (replace X with the appropriate number).
You then have the RFS file mounted & available to copy files from.
Under Linux you just mount it as a loopback device, OS X doesn't really support this functionality though, so this is a good workaround.
If you do need a FULL Euro firmware to play with, then you can get one of the full 550MB+ images from the FUS server;
http://fus.samsungmobile.com/Phone_Binary/9/GT-P1000_P1000XWJJ7_P1000CPWJJ5_P1000XXJK5_P1000XWJJ7_XW_CPW.zip.enc
Get the decoder util from: http://db.tt/i0yM0Py
Copy it into the same folder as the .enc file, and from a windows commandline, in that folder, run:
Decodertest.exe GT-P1000_P1000XWJJ7_P1000CPWJJ5_P1000XXJK5_P1000XWJJ7_XW_CPW.zip.enc 7161632

(Remove the space before _XW that the forum is putting in for some reason)
See: http://forum.xda-developers.com/showthread.php?t=838961 for more info.
I'd recommend against flashing .RFS files from this archive unless your tab is orginally an unlocked model from the UK. Flashing the entire .tar from Odin will almost certainly freeze unless you're running an original untouched CPW firmware. (You can check this with the Check FUS tool from the market).
Cool to know, thanks. I've wanted to reinstall Nova HD since I upgraded first, but didn't know where it could be found, and Samsung don't offer a way to reinstall it.
Hell, if it was on the Market I'd just buy it again, but that option isn't available - and I won't use Gameloft's horrendous broken process to buy it either.

What was the output of the various commands?
Which RFS file(s) are you trying to mount, and from where?
What version of OS X are you running?
hidden.rfs from JM6, running 10.6.5.
Nothing peculiar with the terminal outputs.

How big is the JM6 hidden.rfs? The one from the CPW ROM is over 200MB.
About the same.
Your original post didnt say what hidden.rfs to use, so since im on JM6, thought i'd mount the one from JM6, but should still mount right?
Maybe will try the hidden.rfs from JK2.

Doesn't matter what .RFS file it is, the instructions should mount ANY valid .RFS file.
you can find something interesting like Nova in the XWJJ3 firmware (hidden.rfs).
I had to mount in ubuntu with loop, because on Mac os I couldent see the content of the mounted volume, once I clicked on it the mouse pointer changed to loading and stucks!

Thanks. Here's my steps:
1. Download 2.2ROM from this post: http://forum.xda-developers.com/showthread.php?t=895448
2. Download unyaffs.exe from this page: http://jiggawatt.org/badc0de/android/index.html
3. Download MotoAndroidDepacker.exe from http://modmymoto.com/forums/showthread.php?t=530781
4. Use MotoAndroidDepacker.exe unpack 2.2 sbf file, then you got CG39.smg
5. Unpack CG39.smg by unyaffs.exe, you should get /system folder if everything goes well, then just delete or add anything you want and pack a new SBF at last.
For more support of unyaffs, please visit http://code.google.com/p/unyaffs/
Yes, I did that in the CMD line which running as administrator. But it always shows "stop working"
Would it be possible to flash new/recompiled boot.img/system.img via recovery then?
Or partitions with digital signatures should be also updated?
i#m downloading the files, but it will need some hours; very slow line.

Yes, it's okay. I've flashed a recompiled froyo sbf with a old CG39 which from 2.21UK sbf successful, of course this rom cannot running but it's a good start. Next, we need to unpack the CG39 and modify that.

Let me know if you guys need hosting for project files or roms, we need to get rooted froyo for the Defy!
the depacker didn't work here. sorry. don't know why.
I just had an idea... I wonder if you could extract the froyo Dialer app and add it to the 2.34.1 rom.
Well, there's only one way to find out.
unyaffs never worked for me with CG39. I've tried that when I first got the phone. My guess is that it's not pure yaffs filesystem image, or that the unyaffs code it's buggy. I've tried modifing it prior to compliling, but all I got was different errors, from Stack Overflows to program hardcoded messages like the filesystem was not properly built.

How to change bootanimation runnig stock.

Hi, I am currently using stock JB with a couple of mods/extras i managed to link in via the kitchen. But frustratingly so I cannot change the boot image and are hoping with appreciation someone in here can direct me. So far I have tried everything I am capable of. That is from within the kitchen enabling the function which is suppose to allow you to change your boot animation. Although it gives you the tick and creates a different directory for your boot animation this still doesn't work. I have tried replacing hTC_boot_one.zip file but does not work. Whenever i do replace or alter that file the boot starts as normal with white htc and then goes to black with android with a back light rolling from side to side, like kit in night rider. I also have tried flashing Mattmans-Boot-Animation which uses aroma installer. Still didnt work and as far as I know it just added the file in system/customize/resource/. There appears to be a command file preventing any changes internally in stock. Really appreciate and hope someone can help. Thanks in advance......happy new years.....:good:
Did you root the rom ?
You need root acces to write in the system directory's ......
You need SU

Have you mounted system as rw? In root explorer you just press the button, not sure on other apps, and have you set the right permissions? rw-r--r-- to match everything else in system/customize/resource.

If system is mounted as ro (read only) you can't change anything in the folder, this is the default setting I think and it needs to be mounted as rw to allow changes.
You could try to rename something in the system directory and if it doesn't actually change then you need to change it, or check if the filesize of the boot animation you replace changes.
Like I said, rootexplorer app changes it with a tap of the button, not sure what else to use

Thanks again. No problem renaming any file within system so I guess it is mounted as rw. As to file size, i have tried different file sizes and identical file sizes to the hTC_boot_one.zip file. I have even tried using the same Zip file and just replacing with different images. Making sure to end up with the same values. Nothing seems to work.
Strange, I had rooted stock Rom and it worked fine, maybe you have the wrong format of files or haven't zipped as store only, no compression. I assume it is a sense one x Rom?
Maybe try this one I made for the Rom I use

Sucessfully flashed 98.18.78 recovery into Locked 98.30.1

I understand it is currently not possible to unlock a Razr M with 98.18.94 or 98.30.1 OTA. Never the less, I had been trying to restore a previous VooDoo root that I deleted before the last OTA. Through the experimenting, I screwed up the flash on my phone, and recovering it, I found something that might be interesting.
As others pointed out, downgrading does not work. Flashboot gives various errors. When I screwed up my file system, I was able to flash from 98.18.94 (which I had) to 98.30.1 (which was the only download I could find) using RSD Lite. I was lucky it worked. And since I have been able to experiment and keep flashing 98.30.1 over and over.
I would like to report that in my experiments, I noticed an interesting fact about the recovery.img:
I am able to flash stock 98.18.78 recovery to my phone running 98.30.1.
I have verified the recovery.img contents are not the same, according to a WinMerge file compare, they are ~10% the same
When I try to flash twrp or cwm recovery, the only fastboot error is to the effect "wrong partition size".
The size of .78 and 98.30.1 recovery are the same, 10,485,760 bytes
On the other hand, if I try to flash the .78 system.img fastboot, or use RSD lite to flash .78, I see different security related errors on the phone's fastboot screen- none of which mention partition size. Of course, this is related to the Locked Bootloader I have.
What I wonder is, since the error for the recovery.img is not a security related one, but one of size, and the fact that it took recovery from .78- I wonder if a cwm or twrp made to be the same size as stock Moto recovery, would it be able to sneak in?
Right now my Razr M has gone from 98.18.94 to 98.30.1 with a 98.18.78 recovery. And I'm working ok.
I am not a professional Android Dev. But I am going to do the research and try to modify a cwm type recovery to match the size of a Moto recovery, and see what happens.
I invite anyone with real experience to contribute.

I have already found that if I take the OTA recovery and unpackbootimg and then mkbootimg without changing anything.. it recompiles down to aprox 5mb, which is different than the size it started from Moto.
So I am looking at if the size is set in how the img is compiled.
30.1 and .94 are the same updates, just different system versions. As for the other stuff, I'm not even sure what to say. I'm with Avi on this, I definitely would like to see what a dev has to say.

I found out via a hex editor, both files have empty data insert after the same point, with certificate data at the end, and it winds up making each file the same size. The data before the 'empty data' in each file is mostly different bits.
My current problem is that when I decompile an img, and recompile it, it's bigger, meaning that I cannot insert the 'empty data' at the same point they did.

They are both signed with the 128, or more, bit code. Which is what makes this a such a Loooooong shot.

Well, you'r right on the money. I appended data to a CWM recovery the same as Moto did to thiers, including the certificate at the end.
I didn't get a partition size error this time, but I did get a 'Failed to hab check for recovery'.
Granted, I didn't manage to place the 'empty data' at the same point in the file as the stock roms did. Other than that, it must be the certificate.

No, because it first checks the size (or whether it's a valid image at all) and if the size is correct, it checks the signature.
I found that I can put recovery all the way back to 98.15.66. I haven't tried further back due to kernel version.
I tried to then apply an update ZIP to something pre 98.30.1, and it passed validation (woohoo), but if failed an assert that checked the version in the props. (cry)
I wish there was something in the older recoveies we could exploit.
Really glad to see someone is still trying to find some sort of exploit for this device in it's updated state, it seemed like everyone had completely given up on it. My girlfriend recently grabbed a used Razr M to use for a while but it's fully updated, and I would love to be able to root it for her. I'll be following this thread to see if anything comes of this recovery downgrading
I'm pretty sure you can edit the props from what I can remember.

I found that I can put recovery all the way back to 98.15.66. I haven't tried further back due to kernel version.

The razr hd (2), atrix hd, photon Q all use a recovery w/ same key. Git to work man!
Re:
So, it is RSD that is keeping it from flashing, would the bootloader(locked) boot a recovery partition that isn't signed? Has anybody tried to dd the recovery partition? I will grab a TWRP dd recovery image if you guys have an interest in trying that.
It would still require root and either a terminal emulator or adb shell.

Am I alone here now?
Does anyone with a locked boot loader want to try this? I could create a windows shell script to make it easier if that's the worry.
I am willing to try it out. Win 7 64bit... pass me needed staf to flash it

I'll post it in just a few minutes. I will also post the required commands and we'll be backing up current recovery. If it fails, it should be no problem to restore your backed up recovery.
Download TWRP image on your phone from: titanroms.com/upload/rec.img
Please get to an adb prompt and run these commands:
su
cd /sdcard
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/sdcard/recbak1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/sdcard/recbak2.img
Please ensure that both copies are 10MB. The dd command should end by saying "10485760 Bytes Copied" on all of the "dd" commands.
Now, you should have two backups of the recovery partition and the TWRP Image you downloaded from here all on your sdcard.
You can follow with these commands AFTER your backup has completed.
cp /sdcard/Download/rec.img /sdcard/rec.img
dd if=/sdcard/rec.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=twrprecbak.img
mount -o remount,rw /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.bak
mv /system/recovery-from-boot.p /system/recovery-from-boot.bak
reboot recovery
In the event of a failed attempt at this you can run the following from adb:
su
cd /sdcard/
dd if=/sdcard/recbak1.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
Give me a holler if you don't understand this well. Good luck, guys.
I am gonna try it out tomorrow,i dont have time to do it tonight cause i need to go to work. My pc on work does not have internet connection I will keep u guys posted on any progress.

Just wanted to say I flashed the old ICS recovery to mine using fastboot commands but it didn't get me very far though.if I then try and flash the corresponding blur zip from recovery it just says invalid signature. Was trying to find a way to downgrade so I could get rooted..

Cyanogen 12.1 test builds for Raspi2

Download:
https://www.androidfilehost.com/?w=files&flid=39635
Let me know if these work out for you. You can smack the ramdisk to the original kernel zimage to make the boot.img partition.
Source will be released if this works...
Cheers!
hey!
i would really love to test this.
im just now sure how to get the different .img-files to my SD card (win or osx)
do i partition manually first and then write each IMG seperately? what file system?
i'm really interested in this since im planning to construct my very own RPi2-Android-Car-Headunit...
I really wold like to test this out, I would really appreciate when someone gives install instructions
@Childofthehorn
don't take this the wrong way but can you highlight the zImage your referring too?
are you talking about the android generic device kernel?
are you talking about pulling it from another distro?
just a tad more explanation and I can give this a try. I have scoped out your git for some other clues but come up empty

As there is no kernel provided, try raspbian kernel first
I will check it later as I have a "working" lollipop kernel for rPi2 somewhere, but I have to find it

Thanks, if we can get some source of stuffs working i would give building a crack as well

Hi, news about it?

I'm buildind inside screen, so I cannot scroll (I have no idea, how to do that) and the error message is outside of the 80x50 terminal I'm using

Many thanks for your effort.
If you could build it and boot it, please create your own topic so you are able to upgrade changelog and so on..

Well, You could redirect the output to a file and read that file using vim. To redirect to file run
Code:
command > file.txt
Is it possible to write install instructions?
yes,I want to obtain the install instruction.

I'm interested too!
partition boot as fat,system as ext4, cache as ext4, and data as ext4, then restore file.

To put also stderr to the same file use:
Code:
command > file.txt 2>&1
To use different files:
Code:
command > file.txt 2> err_file
Another possibility to see output and stderr on screen and also put it in a file:
Code:
command 2>&1 | tee file.txt
