I've been trying to recreate a flashable firmware based on the stock TMobile flash dumps and I have complete success.
Heres how to save your current firmware. It will be saved with all apps and settings except for whats on /sdcard.
I recommend reseting to defaults using "Settings->Privacy->Factory data reset" if you want to give these files to someone else to build a flashable rom for you. That will delete all your personal information.
Note: I just backed up a completely setup AT&T Tab, with tons of apps and customizations and restored it to my stock T-Mobile Tab, perfectly! Every app works, home screen is setup perfect, everything!
Effectively this is equivalent to a nandroid backup.
I'll call it "Roto Backup"!
Code:
mkdir backup
cd backup
adb shell su -c "dd if=/dev/block/bml1 of=/sdcard/boot.bin bs=4096"
adb shell su -c "dd if=/dev/block/bml2 of=/sdcard/pit.pit bs=4096"
adb shell su -c "dd if=/dev/block/stl3 of=/sdcard/efs.rfs bs=4096"
adb shell su -c "dd if=/dev/block/bml4 of=/sdcard/Sbl.bin bs=4096"
adb shell su -c "dd if=/dev/block/stl6 of=/sdcard/param.lfs bs=4096"
adb shell su -c "dd if=/dev/block/bml7 of=/sdcard/zImage bs=4096"
adb shell su -c "dd if=/dev/block/stl9 of=/sdcard/factoryfs.rfs bs=4096"
adb shell su -c "dd if=/dev/block/stl10 of=/sdcard/dbdata.rfs bs=4096"
adb shell su -c "dd if=/dev/block/stl11 of=/sdcard/cache.rfs bs=4096"
adb shell su -c "dd if=/dev/block/bml12 of=/sdcard/modem.bin bs=4096"
adb shell su -c "tar -czvf /sdcard/data.tar.gz /data"
adb pull /sdcard/param.lfs .
adb pull /sdcard/zImage .
adb pull /sdcard/factoryfs.rfs .
adb pull /sdcard/dbdata.rfs .
adb pull /sdcard/cache.rfs .
adb pull /sdcard/modem.bin .
adb pull /sdcard/efs.rfs .
adb pull /sdcard/boot.bin .
adb pull /sdcard/Sbl.bin .
adb pull /sdcard/pit.pit .
adb pull /sdcard/data.tar.gz .
Note you will be prompted for superuser permissions on the Tabs LCD on every dd command.
If you don't have the tar command on your tab, install Busybox Installer from the market.
I just paste the above commands into my command shell window and when im done all the files are siting in my current (backup) directory.
Roto Restore:
First flash the data back:
Code:
adb push data.tar.gz /sdcard/data.tar.gz
adb shell su -c "tar -zxvf /sdcard/data.tar.gz"
adb reboot download
Now flash the dumps with Heimdall:
Code:
heimdall flash --kernel zImage --factoryfs factoryfs.rfs --modem modem.bin --cache cache.rfs --dbdata dbdata.rfs --param param.lfs
Of course you could tar the files right n the Tab and flash via Odin if you really want to:
Code:
adb shell
cd /sdcard
tar -cf mybackup.tar cache.rfs dbdata.rfs factoryfs.rfs modem.bin param.lfs zImage
exit
adb pull /sdcard/mybackup.tar .
Nice

The Tmo dump/restore is a test. I want a solid backup/restore and custom rom creation solution.
Fair enough. But is the custom recovery being developed (and progressing nicely) not a solid enough solution?
I won't know till its functional.

Do you not have other android devices? I know of none where it doesn't function. So there is no reason i wouldn't wait a little longer for this to be ported.

A nandroid backup of my rom isn't something I can post publicly on the net. Regardless, I need to create full custom roms that can be flashed using Odin and Heimdall.

Exactly, you post update.zips and then people use clockwork to flash the full ROM. On device recovery is much better than Odin method and more accessible to noobs that have an aneurism when they see the Odin iterface.
As for dumping your ROM to customise, well, yes, either this way using dd or decrypt the Odin flash files.

No, it sounds like he's trying to do exactly what he says he's doing, and that is to recreate the base TMo firmware from DD dumps!
Why? So that if necessary he could return to complete stock if he wished, and because there is no stock TMo image available.
A Nandroid backup doesn't cut the mustard in this case.
Remember guys - just because you don't see a need for something, it doesn't mean that that need doesn't exist for others!

I forgot entirely that the Tab some people have might be carrier customised, mines a generic one so I can flash any of the generic dumps to put it back to "stock".
So yes, a Tmo stock firmware is useful for you guys.

Perhaps you can point me to the code that I'm re-inventing that you are obviously familiar with?
Thanks in advance!
rotohammer: I've been looking for the ways to dump the firmware like you are suggesting for the AT&T version, mainly because the only available dump is an older version that stock. So far all I've found is this from another post by you:
I would like to get various Vibrant radio dumps if someone would be so kind to do so. The command from adb shell is:
Code:
dd if=/dev/block/bml12 of=/sdcard/bml12.dump bs=4096
Lets discuss what we've tried in this thread.

The instructions seem straightforward enough for anyone who has used dd before. How were you able to ascertain the location of this (and other) pieces of the firmware? (Interested to know prior to trying to enable voice on my Tab by swapping modems and reflashing. I'm familiar with Samsung devices since I have a Captivate, but not too reassured that the newest firmware available to restore to is older than launch date.)

The Tab follows the flash layout of other previous Samsung phones, so just google them, the info is out there. I stare at hexdumps to identify/prove what each partition contains, no big deal.
I feel that once some more official firmware is released all the need for reconstruction of dumps will eliminated.
Figured I'd chime in here from my experience, since I've gone through it with the Epic 4G....
The .rfs files and .lfs files won't restore with redbend... and don't touch bml1 and bml4... that's the boot.bin and sbl.bin... screwing with those can lead to brick...
Current roms for the Epic 4g use update-script or updater-script (different formats, updater-script requires update-binary. The scripts get flashed with clockworkmod... first, system is formatted, then the system files copied over, then permissions given to the files. The kernel is flashed using redbend, along with modem (ours require updater-scripts and a modem_delta file if not using odin).
I browse .rfs system images by first creating a /mnt folder on the sd card. With busybox, use the following command:
Code:
Busybox mount /sdcard/factoryfs.rfs /sdcard/mnt
[/card]
I've gotten the factoryfs.rfs from the stock tars...
Maybe this is reinventing the wheel, but maybe it'll help.

Gotcha. Thanks. So, for restores, do you use redbend_ua or does a simple reversal of the dd command work? (admittedly this is an area where I haven't quite dug into yet)

You must use redbend_ua, Odin or Heimdall (theres others too). You can't write to these partitions with dd alone, although there is an app that allows you to use dd too.

I'll give that a look, don't know why it didn't dawn on me to give a look at the ROMs for my Captivate again. I've looked inside an update.zip file before, but didn't really delve into the script inside.
As for the actual dumping of the images, when dumping the .rfs files, what's the difference between using, say, /dev/block/stl9 versus /dev/block/bml9? Will one work and not the other?
What I'd like to be able to do is dump a current stock AT&T ROM since the one posted is older (and possibly an engineering ROM from what I recall reading.)

Why the failure?
Probably because the file systems were still mounted at the time the dumps were made, the zImage partition and the modem partition are not mounted at runtime.

Here is a thought, although I may be completely off base:
I noticed that you can access the ADB shell if you boot into stock recovery, perhaps you can mount the SD and dump a few more RFS images?
There's no G-Slate forum yet, so this goes here.
How to root your T-Mobile G-Slate
This process works under Linux. The hard part under Windows would be mounting a file as an ext4 filesystem, but if you can do that you win.
You need:
The four files in the gslate_root.zip archive attached to this post.
To root:
Put those four files in a directory and open a terminal to there.
Shut down your G-Slate and plug it into your computer via USB.
Hold down both volume buttons and press the power button. The G-Slate will not appear to turn on, but it'll go into APX mode.
Running "lsusb" should show an entry "0955:7820 NVidia Corp."
Run the command "sudo su" to get a root shell. Running "ls" should still show the four files.
./nvflash --bl bootloader.bin --getpartitiontable ptable.txt
./nvflash -r --read 8 system-orig.img
Wait while 400 meg of data copies.
cp system-orig.img system.img
mkdir system
mount -o loop system.img system
cp su system/bin
chmod 4755 system/bin/su
cp Superuser.apk system/app
umount system
./nvflash -r --download 8 system.img
Wait while it copies back.
./nvflash -r --sync
Press the reset button under the sim cover to reboot.
There's your rooted G-Slate. Making that process "one click" is going to suck.
Troubleshooting:
You may need to install the package libstdc++6 or lib32stdc++6 to get nvflash to run.
You may need to use "sudo" on the nvflash commands.
If you want to try to make this work on Windows, the nvflash.exe binary and the APX USB drivers are are available from nvidia.com
This is unbelievable! Can't wait to give it a shot.
EDIT: For future reference, DO NOT use Virtual Box to try and root your device. There are issues getting the drivers to work properly. Lsusb will not work. The following methods have been tested and work:
1. Wubi install of Ubuntu Linux
2. VMware install of Ubuntu Linux
3. Dual-boot install of ""
4. Dedicated Linux box (duh)
And remember: If at first you don't succeed, try try again. Then visit our IRC channel.
Trying this on Windows 7 is gonna be a trip. Never workt with ext4 before.
Install Ubuntu and you can dual boot into Windows or Ubuntu. That's what I do.
Sent from my LG-V909 using XDA Premium App
This method is confirmed working. Thank you so much for the hard work Chandon. It wasn't very hard to complete on Linux. I can't believe my G-Slate is rooted!!!! Hell yes! Oh and the device is not wiped during the process either just to let everyone know!
Some More Help
Would it be possible to pull the recovery partition off now?
Why I ask. I am in a bit of a pickle. My slate will get to the first LG boot screen and then freeze. It does not even go to the boot animation. I can still get into fastboot and APX mode and it is seen by my computer.
How did i get here. While poking around in fastboot I am pretty sure i wiped they recovery partition D'OH.
I was able to complete the steps listed (for root) with out issue but still cannot get past the boot screen since this is only modifying the system partition.
I am thinking that if that could be pulled from the device i could flash it to mine and bring my slate back to life?
Am I way off on this one?
SmellyTunic -
Attached are all the reasonably small partitions that I could pull off my device with nvflash. This should be everything except /system, /cache, and /data.
I suggest backing everything up before flashing any of these, on the off chance that there's some difference between devices.
Thanks so much for this! Is there a good linux live cd(or bootable usb flash drive) someone could suggest where this could be accomplished easily? Not ready to take the plunge actually installing linux on my system yet >.>
Here you go
shinkinrui
Info and steps can be found here http://www.ubuntu.com/download
Pretty easy to set up a dual boot machine.
Chandon,
Any chance you know off hand which one of those partitions is the recovery?
I suggest doing a Wubi install [1], where Ubuntu pretends to be a Windows app (which you can then uninstall like any other app later). Alternatively you could try using VirtualBox [2], but that's less guaranteed to work.
The only reason I wouldn't do this with a Live CD is that you'd risk losing your backup of the stock /system partition when you reboot. It would also make losing power in the middle of the flash really annoying.
[1] https://wiki.ubuntu.com/WubiGuide
[2] (edit: virtual box doesn't easily see the USB device)
Thanks guys, reading about that Wubi solution looks like the simplest way to have a dual-boot system. I like it! I'll be getting my root on later tonight
i prefer Ubuntu just cause you can install it in windows then simply restart and boot into Linux or Windows. This way you don't need to worry about not having Linux again.

I'm sure that /system is 8 and the kernel is 13, but don't know about anything else. You might be able to figure it out by reading the ptable.txt file generated by the --getpartitiontable command - it's pretty clear except for the part where it uses 3 letter partition names.
Thanks. I will take a look when i get home from work.

No kidding. Since the linux method failed miserably for me, I've decided to press forward with trying to do it on Windows. Problem is, I have yet to find any way to mount an ext4 filesystem on Windows. There are several options out there that will allow you to read ext4 filesystems on Windows, but not write. Any suggestions?
my friend will be happy to see that this is possible.
Could someone run
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/unbrick.img bs=512 count=524288
and upload it? Flashing unbrick in a 'raw' fashion will allow you to hard brick most Qualcomm devices. Unfortunately I lost my backup and I can't boot my device. This file will allow me to recover. Thanks!

Make sure you're running as root, from adb shell or terminal emulator. Try this one instead
Code:
dd if=/dev/block/mmcblk0 of=/storage/extSdCard/unbrick.img bs=512 count=31250
That command should have created 'unbrick.img' on your external SD card. I am extremely thankful for you doing this. My device is bricked and sitting in QHSUSB_BULK mode. You may want to save this file in case you ever need it! Thanks again, it is very much appreciated!

Afternoon all,
My G4 has hit the bootloop for the last few days. Periodically, it has powered up to the main screen, but not for long enough for me to recover data.
I just spoke to a data recovery place that told me that if I can put my phone into download mode, they can recover the data. Lo and behold, my phone is currently next to me in download mode!
I'm quite keen to avoid dropping that amount of money if possible, so does anyone know of a way to recover the internal memory of the phone via download mode?
Apologies if I'm duplicating a previous thread - I had a quick look, but couldn't see any with the same issue.
Probably when the phone is in download mode they can copy the partitions bit by bit then try to do data recovery from those partition images.
So if the phone doesn't boot, it doesn't mean the data partition is corrupted so in theory you could try to copy the data partition and mount it and see what files you can recover.
I do not know the exact commands to dump the data partition but I think that's the way it can be done.
Anyone else willing to give a hand here?
Thanks for the help so far. I believe the data is intact - when the phone starts up, the data is all there. It's just accessing it that is the issue.

something similar to

dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/mnt/media_rw/external_SD/data.img
OR
Code:
dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/dev/block/mmcblk1/data.img
don't quote me on that but in theory this should work...
make SURE you have a 32gb SDCard in the phone first
Where would that command be entered mate? Sorry, only ever used my phone stock before.

You need to mount the partition first.
Also, you could mount data if it is not encrypted (is it?)
Do this:
Code:
mkdir /temp
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/
A little tip that should work :
Take the battery off your phone
Put both phone and battery in the fridge
Wait till the phone is cold and boot the device.
The bootloop trouble is due to an abnormal warm so this way you can have a one shot normal boot to backup your data before send for warranty.

just a question though... How can you use this command if it will not boot?
---------- Post added at 08:59 AM ---------- Previous post was at 08:50 AM ----------
to get into download mode do the following...
Pull Battery
Hold Volume Up
Plug in USB Cable (make sure it's plugged in the computer)
Release button after 5 seconds
follow the link to grab the files needed for "Send_Command"
Grab LG Root here
once you are in the mode and you followed directions you can copy the command I wrote
above to copy your data partition. The reason you must have a 32gb+ SDCard is you will
be making an exact copy of the /data partition where you can remove the SDCard and recover
whatever is needed.

there is no need to mount the partition first..
the dd command will copy the partition as a RAW image.
you must then take it to a computer and mount it as an EXT4 or use it with ext2explore

in that case the command you have given him will copy 4492 mb only.
Here is why:
Code:
dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/dev/block/mmcblk1/data.img
input_file=(some partition) block_size=8192 skip_this_much_data=65536 how_many_data=548352 output_file=(somewhere)
actual data copied is 8192 * 548352 = 4492099584 bytes, and you are skipping some data from the beggining with 'skip'
you do still need to mount the sdcard, the "mmcblk1" is not treated as a directory, and it is very unlikely the sd card is mounted automatically in download mode.

remember me saying (if you read) above that I said "something similar to"
Hi all. Firstly, thanks for all your responses!
I've not got much of a clue what I'm doing unfortunately, I've never really messed with Android before - I'm typically fairly computer literate, but I've steered clear of messing with and rooting phones for the most part.
So to clarify, I've downloaded LG Root, Running either of the exes just leads to a cmd box that's open for about a second before closing, so I'm presuming I've missed a step. Is there a guide already in existence on how to use it?
But once in, ensure there's a sizeable Micro SD card in (it's a 64gb so I should be okay!) and use the send_command exe to send:
Code:
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/
And then the entire image should be on the Micro SD card.
How would I then mount the data image to be readable? I've only used .iso for mounting before.
Apologies for my ignorance - I'm probably making helping me quite difficult!
Sorry all, correction to my previous:- Do I basically follow http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
And replace step 10 with the above command?
Shift+Right Click the folder you extracted "open command prompt here" for starters...
Run ports.bat first...
It'll tell you your DIAG and communication port...
The second com port is the one you are looking for.
Send_Command \\.\Com"#" (don't insert quotes, # being the number you found)

I'm having the same issue and actually tried this earlier today. Ports.bat didn't show a DIAG communication port even when I had the phone stably sitting in Download Mode.
Going to try the freezer trick. I already bought a Nexus 6P, just want to unlock the locked content on my SD card. lol.
EDIT: Holy crap! It worked. I chilled it in a baggie, then stood in front of the freezer as I unlocked all of my locked gallery files (1,411 files totaling 900MB). As soon as I was done, 30 seconds after stepping away from the freezer, it started to bootloop again.
Got the only information I needed off my phone...nice! I might give it another go tomorrow and see if I can't run ROM Toolbox and backup all my apps so it'll be easier to push to my N6P.
Awesome suggestion!

Mine will only get to optimising Apps, even if still in the freezer.

Hi all, sorry for the double posting, but just to make certain before I do something that will accidentally brick my phone. I'm intending to do the following:
Put phone in download mode and connect device.
Open LG_Root folder
Run a command window in LG_Root
Code:
Send_Command.exe \\.\Com4
Then, line by line, command:
Code:
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/
Once I've done all this, what happens next? Will I see responses on the screen etc?
Again, I apologise for the probably stupid questions. I don't want to brick my phone and lose all of the data, but I'm going away with work so would like to square it before I go if I can.
Many thanks to you all so far.
Can anybody give me 'mmcblk0.img' file for htc 10(2ps6500/2ps6500). if the phone is rooted and busybox installed it can be extracted using adb command.
To view partition tables :
adb shell su -c ls -al /dev/block/
After running this you can see this partition mmcblk0 in starting and make sure that the partition is available.
First you have to backup your file.
To backup into internal memory run this command:
adb shell su -c dd if=/dev/block/mmcblk0 of=storage/sdcard0/fulldump.img
or
To backup into external memory runthis command:
adb shell su -c dd if=/dev/block/mmcblk0 of=storage/sdcard1/fulldump.img
the file is supposed to be in GBs, so copy the file in pc, make a zip/winrar archive and upload it.
It would be a great help for me as I'm stuck with a bricked device. Thanks in advance
Capturing it now. I'm on the October 2017 unlocked firmware/ROM (RUU_PERFUME_WL_N70_SENSE80GP_VZW_MR_NA_Gen_Unlock_2.51.617.21). The command I needed to use was
Code:
adb shell su -c dd if=/dev/block/mmcblk0 of=storage/emulated/0/fulldump.img
Code:
adb shell su -c dd if=/dev/block/mmcblk0 of=sdcard/fulldump.img
might've worked, too. I'll let you know when it's uploaded.
Edit: Filled up the 19 GB free space on internal. Let me try to external SD.
Likewise, the command for external SD on this device is:
Code:
adb shell su -c dd if=/dev/block/mmcblk0 of=storage/ext_sd/fulldump.img
Yikes, 29GB but done. And hopefully it will compress a ton in order to upload somewhere. I'll 7-Zip it with maximum settings and see how well it compresses before I figure out where to upload it to. I don't know if I'd be able to upload something that large anywhere - I could ask AFH if it would be cool, even if it's just temporary. Guess we could always try a torrent if you're familiar with downloading torrents. I'll let you know how it compresses. It'll take at least a couple of hours to compress. Right now it's averaging 28% so it'll be less than 10 GB, I think, which is still huge.

You do realize this will give ALL of the info from every partition on your phone, correct? Including IMEI, serial#, and any and all data you have on it?

No, I sure didn't. Thank you! I wondered but in my searches I didn't find that information. Well, forget that, then. [emoji16]
I had even considered, if I was prepared to RUU my 10 (the Pixel is my primary) (but I'm not), to only then capture it after.
Thank you very much!
Thanks for responding, I didn't know that will give all that partition details. I am new to xda. Thanks again.

I hope you find another way to recover your phone. Is it out of the uh oh protection/warranty period?
