No,nothing just a blinking red while on charge.
[Xperia Z Original Android Development] [NUT]:
While _not_ on charger, power+volup does nothing either?

Some seconds is more like 6 and more, as long as your phone vibrates its kinda alive.
[Xperia Z Original Android Development] lilstevie:
uh.... you do realise that by restoring the TA you are locking the phone back up, which means no more custom kernels. The kernel is sigchecked on boot if you are locked.
[Xperia Z Original Android Development] fareeed:
Is the flash tool method for dumping the Ta identical to this method?
[Xperia Z Original Android Development] Hellscythe:
when i nagivate to dev/block/mmcblk0p1 on my phone, my phone shuts off :S

is that meant to happen?

using ES file explorer

Locked bootloader, rooted, running KA06
[Xperia Z Original Android Development] Droidphilev:
Hi OP,

Would you be so kind to repost the commans you used before to backup and restore (the ones for ADB or terminal)? You removed them from you post.

Many thanks!!!
[Xperia Z Original Android Development] Egan:
Backup: cat /dev/block/mmcblk0p1 > /sdcard/ta-backup.img

Restore: cat /sdcard/ta-backup.img > /dev/block/mmcblk0p1

However I prefer 'dd' instead of 'cat' because it's more low-level, provides more info on what the input was and output and appears to be less corruption prone.

Backup: dd if=/dev/block/mmcblk0p1 of=/sdcard/ta-backup.img

Restore: dd if=/sdcard/ta-backup.img of=/dev/block/mmcblk0p1
[Xperia Z Original Android Development] [NUT]:
I was actually not surprised it didn't work, the surprise I had was being able to restore it :rolleyes:
[Xperia Z Original Android Development] Droidphilev:
hi,

Thanks!

with cat i had different md5 in terminal. dd had thesame md5. wierd
[Xperia Z Original Android Development] [NUT]:
cat treats the stream as ascii, dd treats it as binary, in the translation from the source (binary) to the destination (ascii) (and back) things are open for interpretation by fs and os...

Best is not to use cat and go for dd every time...
[Xperia Z Original Android Development] Egan:
Exactly! Way too dangerous to use cat for this, especially since it can so easily hard brick the device.
[Xperia Z Original Android Development] Droidphilev:
Hi,

Thanks for the very important info. I will just backup on the phone itself using terminal i guess. I don't know what command is used by the tool in OP.
[Xperia Z Original Android Development] Egan:
I checked for you and it seems the OP has also switched from 'cat' to 'dd'.
[Xperia Z Original Android Development] gm007:
No vibrations with all key combinations.
[Xperia Z Original Android Development] [NUT]:
wow... that would mean that your phone's primary bootloader is gone/corrupted :eek:
[Xperia Z Original Android Development] gm007:
That's a bug in the rooting method,this has been discussed many time.check the rooting thread for a fix.
[Xperia Z Original Android Development] nope00:
I'm on Xperia S, somone can confrim this method worsk well ?
[Xperia Z Original Android Development] Egan:
What is the size of your mmcblk0p1 partition? Also can you find your IMEI and serial number within it?
[Xperia Z Original Android Development] [NUT]:
1: Exactly 2Mb (2048kb).

2: Yes.
[Xperia Z Original Android Development] Egan:
Do you also have xperia S?
[Xperia Z Original Android Development] [NUT]:
Nope, only an ARC and a Z :)

Why ask?
[Xperia Z Original Android Development] nope00:
I made a backup its 2048kb, how can i check in it the imei and serial? how can i open it?
[Xperia Z Original Android Development] [NUT]:
You will need a linux machine for that or you might be able to mount it in android terminal.

You create a loopback device /dev/loop0, or if that exists you can increase the digit one at a time to a maximum of 9 (I believe that's the maximum), and then mount the created TA image through that loopback device on a mount point somewhere, android might not have the filesystem module/support, if thats the case, you need a linux distro on VM or PC.

Read how: To mount a disk image on Linux or Mounting a raw partition file made with dd or dd_rescue in Linux . The commands should be the same for android terminal, except for parted but there you have fdisk.
[Xperia Z Original Android Development] Egan:
Because you gave answer for noop00 ;) .
[Xperia Z Original Android Development] [NUT]:
ROFLOL :laugh: :eek: :silly:

I thought you where asking how... I misread your post :D
[Xperia Z Original Android Development] rickwyatt:
please download the new tool it now has md5 check for both

dev/block/mmcblk0p1 and the backup make sure thay match

please hit the thanks button or donate my tool helped you
[Xperia Z Original Android Development] lilstevie:
TA is not this kind of partition, it is a data store that has no filesystem just like the kernel partition is (notice how you cannot mount that either)
[Xperia Z Original Android Development] gm007:
So can we use this tool without any risk?
[Xperia Z Original Android Development] Marsou77:
Look at the screenshot, MD5 from dev/block cannot be read because it's not found.
[Xperia Z Original Android Development] rickwyatt:
reboot phone and try again
[Xperia Z Original Android Development] Egan:
Never
[Xperia Z Original Android Development] gm007:
Never in this situation means always risky?
[Xperia Z Original Android Development] [NUT]:
Ooh, so its a cpio archive aswell then?
[Xperia Z Original Android Development] lilstevie:
yes, writing to the partition which essentially contains the device config for the bootloader is always going to be risky... you of all people should know what one already though with your bricked device
[Xperia Z Original Android Development] [NUT]:
Yes, the risk will never go away.
[Xperia Z Original Android Development] nope00:
I got the same massage. I tried restart the phone and the computer too. But i had the TA.img so back up works I just cant check 100% sure.
[Xperia Z Original Android Development] rickwyatt:
do you have busybox installed? if not ill add it to the tool
[Xperia Z Original Android Development] rickwyatt:
Download the New tool it now has busybox so it should now show the missing md5
[Xperia Z Original Android Development] nope00:
Works fine, now my drm keys are safe now?
[Xperia Z Original Android Development] rickwyatt:
your md5 match so you should now be ok
[Xperia Z Original Android Development] eccomania:
And is it possible to change values in the ta img files? such as imei or serial number and flash it back?

Sent from Xperia Z
[Xperia Z Original Android Development] rickwyatt:
no changing imei its a crime and i will not talk about it
[Xperia Z Original Android Development] Droidphilev:
Hi,

If i generate MD5 in terminal on the machine the md5 is different from the ones that the tool generates. Maybe stupid question but is this ok?
[Xperia Z Original Android Development] rickwyatt:
it should not matter
[Xperia Z Original Android Development] Egan:
It does matter. It means there is a difference, so a chance of bricking the device.
[Xperia Z Original Android Development] rickwyatt:
im testing it now with the tool this is what im doing

backing up ta

unlocking

flashing cm10.1

restoring stock rom

then flashing TA
[Xperia Z Original Android Development] Benjoy Ericsson:
flashing ta.img back also relock bootloader automatically?
[Xperia Z Original Android Development] rickwyatt:
yes as soon as i restore at it locked
[Xperia Z Original Android Development] smardu:
Tested.

It's working.

Many Thanks.
[Xperia Z Original Android Development] rickwyatt:
backing up ta ✔

unlocking ✔

flashing cm10.1 ✔

[Xperia Z Original Android Development] Egan:
It's not about trial and error testing, it's about knowing. You must be absolutely sure the MD5s are correct and matching...always!

To be honest if I were you I would build a fully automated process in your tool that only finishes the backup when it is 100 percent sure it has done the job right. If it fails the user should try again until successful. It should never finish and leave the check to the user who often knows nothing about MD5. Also the correct MD5 should be stored in a separate file and used when restoring. It should check the checksums automatically before the actual restore and fail when they do not match.

As a cherry I would zip the TA image together with the MD5 file when backing up and use that zip to restore. Then it is at least a lot more secure or as much secure as I can think of right now :).
[Xperia Z Original Android Development] rickwyatt:
lol the tool its ok

first it dose

md5sum /dev/block/mmcblk0p1

then this

md5 C:\Backup-TA\tools\backup\TA.img

if both math then its ok
[Xperia Z Original Android Development] Thraxzzz:
I hope,soon,we can somehow mod the TA,and is compatible with all xperia Z...is this possible? :confused: i want the BE2 back :confused:
[Xperia Z Original Android Development] Droidphilev:
Well... it's completely understandable that an app like this needs finetuning (thank OP). I do wonder for the mean time: if i make the backup in terminal on the phone itself, check the md5 in terminal for both the partition and the created image... would that be safe? Since everything can be done without a pc i would prefer to do it all on the machine.
[Xperia Z Original Android Development] rickwyatt:
backing up ta ✔

unlocking ✔

flashing cm10.1 ✔

then flashing TA ✔

The tool is working test it ba2 is still working even after flashing cm10.1 then restoring stock rom
[Xperia Z Original Android Development] Egan:
Yes, you can and it will be as safe as the tool. Just pay attention :).
[Xperia Z Original Android Development] rickwyatt:
heres a video as proof https://www.youtube.com/watch?v=j7JWa7Y6jUU
[Xperia Z Original Android Development] nope00:
One more question if I get unlock key form here :http://unlockbootloader.sonymobile.com/ sony will know im unlocked my bl. Or is there an other way to generate unlock code?
[Xperia Z Original Android Development] Egan:
I noticed that the TA partition changes from time to time (dont know yet by what) and therefor the MD5 also changes. Thats the reason why you sometimes get a different MD5 when hashing the same TA partition. This means that a different MD5 isnt always telling us the TA backup is corrupt. However you should go for a matching pair tough :).
[Xperia Z Original Android Development] rickwyatt:
yep all that matters is that thay both match as i had to different pairs of md5
[Xperia Z Original Android Development] wevie:
Still, it`s a good idea to store the md5 in a separate file, which is checked before the TA is flashed back..
[Xperia Z Original Android Development] Egan:
I've made some good progress in changing the tool a bit to fit the requirements in my post a few posts back. I will share it here later today or tomorrow.
[Xperia Z Original Android Development] rickwyatt:
iv now updated the tool it now checks the md5 of restore to make it safer please download it
[Xperia Z Original Android Development] wevie:
There is no other way right now.. They will indeed know you requested an unlock key, they will not know if you have ever used it ;)
[Xperia Z Original Android Development] Osyx:
It would be great if you added a changelog or atleast some version numbers and history so you can see which version you've got ;) otherwise a great tool
[Xperia Z Original Android Development] rickwyatt:
changes will now be loged in history.txt on front page :)
[Xperia Z Original Android Development] Droidphilev:
hi,

If TA changes sometimes causing different MD5's... who knows what changes and a backup that is, let's say 3 months, old won't kill the phone. Let's hope....
[Xperia Z Original Android Development] rickwyatt:
the md5 change because the phone is writing error logs to the first 500kb of TA

Awesome can't wait to try this, but will have to Wait till I get home from work 13 days to go. But when I rooted my phone I never checked to see it boatloader could be unlocked. At the moment says No how can I check to see if it was the bug that did it :-o
[Xperia Z Original Android Development] lilstevie:
Whether it is possible or not is a giant risk to take, that section of TA is probably signed in some form, so it would be a risk to even try.

Changing serial number is really inconsequential as it really isn't used by much in userland, and you will still have your serial on the box etc. IMEI on the other hand does not appear to be something that you can change. If you supply the incorrect IMEI the modem actively refuses to register any sim card.
[Xperia Z Original Android Development] Osyx:
Reflash stock ftf or repair in PC companion (have to backup or you'll lose your data)
[Xperia Z Original Android Development] Egan:
As said I changed the tool a little bit to fit some requirements: download here (file >> download)

What has changed:

- Removed unneeded ADB Insecure App

- Removed unneeded fastboot

- Removed unneeded busybox

- Now you can extract this tool to any directory of your choosing.

- Added clear progression status while backing up and restoring

- Added restore confirmation

- Backup and restore will be always be unsuccessful when the MD5 checksums do not match.

- It now creates a backup package in ZIP format. In this you'll find the backup image and MD5 file. This package will also be used for restoring.

I tried to test enough for bugs not to be present. However one can always slip through. When so please let us know in this thread.

Since my bootloader is still locked, I did not test the actual overwrite of the TA Partition. Since that is just a simple 'dd' call from ADB I do not think that will fail to work.

@rickwyatt: I hope you see the changes as a positive addition to your tool. Just trying to make the best of it together with you :).
[Xperia Z Original Android Development] snark_be:
If I try to do a backup, unlock the bootloader and something fails, it is possible to go back to a locked bootloader and have everything working back fine?
[Xperia Z Original Android Development] rickwyatt:
@Egan ill add your tool to the front page later if you don't mind that is?

@snark_be if you say flash a custom Rom and it fails you will have to restore your phone back to stock before you refresh your ta backup witch will auto relock you phone

The most effective way to increase the reading speed of our SDcard is here.

There are two ways..

1. Via CWM recovery

2. Using an app

To check your SDcard Read/Write speed download SD tools.

..................

First method

..................

Thread

Requirement : Root

.......................

Second Method

.......................

Either install SD-Booster or SD speed increase. Both of the apps works great.

Open up the app and set the cache value to 2048 Kb. (Recommended)

Tick the option "Set on boot"

Requirement :Root

Playstore :

SD-Booster

SD speed increase

To check the improvement in speed run the SD tools again.

Well, mine improved a lot.

Screens

P.S Use it at your own risk.

Tell me if that worked.

Hello guys,

I have a problem with my HTC Desire X. Every time that I use the sd drive to save something or I switch off my phone, I lose all my applications!

I notice that the problem is collegated with the apps that I have installed on the sd card, because the other apps that I've installed at the internal memory, are perfectly in function.

What huppened?:confused:

Every time I restart the phone or the battery finish, I have to reinstall all the apps that I had on the sd!:crying:

I've heared that with the new version of android the sd memory storage will be replaced from an other tipe of storage, maybe is there the solution? I don't know more. Is anybody there that can help me? :fingers-crossed:
