Android ADB Interface - Digital Signature Information Error

UPDATE (03th FEB 2013) This will wipe your internal storage (/data) but not your SD Card!
UPDATE (06th JAN 2013) : VIDEO TUTORIAL ADDED CLICK HERE

UPDATE:



OK so i was looking around for a easy to use guide i could refer someone to and couldn't find one so i decided to create 1.

With this method you wont need to download the android SDK and instead can download a small package of files that i will upload. this saves around 1-2GB of bandwidth.

Firstly we should confirm your phone can be unlocked. To check if your phone can be rooted (most likely if it is not branded to 3, Vodafone etc then it can be)

Go to the phone dialer
Tap*#*#7378423#*#* then a service menu should pop up,
Tap Service info > Configuration > Rooting Status. if it says boot loader unlock allowed then you are good to go.
if it says not allowed or no then you will need to pay to have the boot loader unlocked.

Now we need to get your IMEI to do this type in the dialer *#06# another window will appear with your IMEI number write this down somewhere as you will need it later.

OK so now that you know your phone BL can be unlocked we will need to download and extract these files

• ADB and Fastboot Package - http://db.tt/B5vG1yn

Now we can begin. Turn of your phone. once the phone is off press and hold the search button while pluggin in the usb lead. the led at the top of the phone will be lit up BLUE. your computer should prompt you to install drivers for the new device if it does then select 'install manually' and browse to the location of the drivers, depending on your system architecture (X86 or X64) select the appropriate folder it should then install the drivers if you get any prompts about unsinged driver just install any way.
if something doesn't happen like it is suppose to please reply here or pm me.

Next we need to go to sony ericsson's bootloader unlock site read through to confirm you understand what your doing then click continue.

Click "yes i'm sure"

ok now check both boxes and press i accept

now we need to fill in these fields (IMEI is the number you wrote down earlier if it doesn't work remove the last number and try again)

Press submit and you will see your Unlock Key copy it for later.

Finally after installing the drivers we will need to run the software called fastboot now to make it easier for you guys i have included a simple bat file which will load CMD at the correct location. so load run_me.bat and make sure the BLUE LED on your phone is still on. if it is then type this in to the new cmd window.

fastboot.exe -i 0x0fce oem unlock 0xKEY

replacing KEY with your key. for example

fastboot.exe -i 0x0fce oem unlock 0x726802F75671552D

your phone should now be unlocked. check my next guide on how to install custom recoveries, kernels and most importantly Android 4.0 (ICS)

Getting an error message when I try to install the drivers, any advice? or am I okay to proceed? Followed your advice on the top 'quote' area on the OP, and got this as a result.

Thanks for the guide (as well as your many others), by the way! I made sure to thank you on the OP.

You need to disable driver signature enforcement, i don't support xperia play any more but this will help

code 10 means device driver can't start, are you using x64 os? if so most likely you need to disable driver signature enforcement (google it)

Thanks for the guide. Very helpful!

 

[davis the droid]

On my Sony Ericsson Xperia Play (R800at) when I go under the service menu I have no Rooting Status at all or bootloader stuff.
I went in this order *#*#7378423#*#* > Service info > Configuration > Rooting Status but found nothing helpful at all. Is it because of AT&T being busybodies trying to control ever phone they bough?

 

[dj___]

What if I don't see any "Rooting Status" at all?..
Service info > Configuration > ??????
A and just see following info here (in Configuration):
IMEI:
*my IMEI*
IMEI Software Verson:
22
Available Speech Codecs:
HR, FR, EFR, AMR_HR, AMR_FR
Working Band/s:
GSM850, GSM900, GSM1800, GSM1900, UMTS_BC1, UMTS_BC8

I did everything very well (and my blue light was shining from the beginning) till this f*ckng point >>>>>>>>>>

>>>> For Windows users, when asked for a driver, point to the usb_driver folder where you placed the android_winusb.inf-file, and select the Android Boot loader Interface-file. (never asked and nothing happened)

4. When your device is connected, open a command window on your computer and go to the platform-tools folder within the Android SDK folder.(couldnt find even I spent hours :crying::crying::crying: platform-tools )

5. Enter the following command:

fastboot devices

6. Verify that you get an answer back without any errors.
Enter unlock key

WARNING! The command below contains your unlock key. If you perform this step, you will unlock the boot loader. This may void your warranty and/or any warranty from your operator.

1. If you still want to unlock the boot loader of your device, enter the following command:

fastboot -i 0x0fce oem unlock 0xCF646E38EC2EA677

2. Verify that you get an answer back without any errors.


>>>>>>please help me from ''...when asked for a driver, point to the usb_driver folder where...'' otherwise one laptop and one Xperia Play will be dust.

links r down
can u reupload?

 

[oleg77]

Hi everyone. We'd appreciate if someone could reupload the adb+drivers package, link is down. Thank you.

edit : Xperia Play USB drivers are here : http://dl-developer.sonymobile.com/drivers/Xperia_PLAY_neo_arc_acroIS11s_acroSO-02C_USB_drivers.zip
Was there something else (except those drivers and minimal adb/fastboot) ?

Sorry to come this late, but I just bought recently a cheap R800i ...

I have a question, regarding this :

Go to the phone dialer
Tap*#*#7378423#*#* then a service menu should pop up,
Tap Service info > Configuration > Rooting Status. if it says boot loader unlock allowed then you are good to go.
if it says not allowed or no then you will need to pay to have the boot loader unlocked.

On my device, there is no "Rooting Status" page under Service info>Configuration...
Does it indicate something about the bootlodaer ? is it unlockable ?
I recieved an unlock code from Sony after entering my IMEI on their site. Does it mean that I should be able to unlock the bootloader of said device ?
Thanks for any help.
