Do not write play with 07da.

Pardon my french, but you guys have no idea of what you are trying to do..

First of all your 07DA are unique and digitally signed to your IMEI and Hardware ID.

Trying to swap with any other one will lead to no network.

If you lost your 07da - you lost your phone, so i would think 50 times before to play with it.

Either a guy from Sony has to be so kind and present the Xperias private key to rewrite and re-sign the 07da or ...

My hope is that you will get back in the unlock bootloader business again. I think you are one of the few devs that actually know what they are doing and have a real chance of getting it done. You were the only one that could crack the Xperia X10 bootloader. Just feel bad that you never got the cred for it. And almost everyone thinks that the_laser did it.....

I to agree with cpumaster maxrfon is our only hope and i htink thta htis time no **** will go down when you do come up with a method to help us locked people out :)

Hi,

Sorry for my bad english :).

There's nothing to understand ... you have to have a seed or stopcock to inject and decrypt sha256 .... believe me, you need the following:

1 or 2 mathematical cryptography experts, one expert in java-javascript, one expert kernels / software, a computer scientist or a network of computers connected together to work for the same end, 4 or 5 xperias do guinea pigs and a lot of patience, maybe with a 1000 cores cumputer we'd need some years.

Or a Sony infiltrate facilitate such private key .... I dread to think, but it's likely that each has its own manufactured xperia private key (which can be known only sony), so that the procedure would happen to not be generic: S and only Sony could unlock the bootloader.

Regards.
[Sony Xperia P, U, Sola, Go] Arteni:
You know, the method has already worked....

Sony Xperia T.
[Sony Xperia P, U, Sola, Go] thanitos:
You can't edit the ta then stick it back in, just like you can't edit an app and stick it back in, everything is signed by a special key thats then read by the phone and allows it to run hence messing with your ta causes loss of service it's not signed so its not run
[Sony Xperia P, U, Sola, Go] bragaboom:
But if the phone check the signature some private key must be in the phone itself. Or maybe is possibile to skip the signature check?

Or not?

[Sony Xperia P, U, Sola, Go] thanitos:
Once you figure out the sign key for the whole ta and whatever encased it and whether or not it's generic you can change it all you want as long as it's re packed and signed like it was before. But who's to say something doesn't write to the ta during boot with a list of data each time so changing the ta may still not work at all, code injection before the denial of a fastboot would probably be simpler
[Sony Xperia P, U, Sola, Go] Gabe.INc:
So, this thread doesn't work at all? :o

I mean, I got my Xperia U (ST25i) with Bootloader Unlock Allowed: No, and is this make it yes? Make my bootloader rootable?

As far as I know it doesn't work entirely yet. I haven't tried it but I believe that it changes the status but then loses all mobile networking capabilities. Our out might not even change the status, read it all back for yourself! Hopefully it should be working soon though...

[Sony Xperia P, U, Sola, Go] pcarvalho:
so we need a way to re-sign bootloader...

what if we modded our bootloader with necessary key and then used the sim unlock server to resign it?

likeit does to unlock the sim lock... it mods the 00007DA...

its just a wild idea :D

but would this work?

am i just dreaming or could this work?....

experts please let us know :)
[Sony Xperia P, U, Sola, Go] Gabe.INc:
Thanks man, but can you explain to me what, exately are you trying to do?
[Sony Xperia P, U, Sola, Go] Galcactus:
The SIM unlock server I doubt would work since, as stated earlier (I haven't chased this up so I'm taking it at face value) each of those 007DA thingy areas are individual and unique to each device. However, I don't know precisely how the tools work so there's an off chance of it working.

As far as I know, and others feel free to correct me, this method works by opening a particular area of android called the trim area and editing the values there which are responsible for the rooting status, along with a few others which effect that. This is a very basic (and possible incorrect) description, read the rest of the thread and Google what you don't know!

[Sony Xperia P, U, Sola, Go] pcarvalho:
it mods the 0007DA to my device... i sim unlocked it and only 000007DA and 2 more simple lines where modded....

if i was sure it wouldnt brick i would try it again...

problem is im not :(
[Sony Xperia P, U, Sola, Go] thanitos:
The update server wont take unsigned items I'm sure
[Sony Xperia P, U, Sola, Go] pcarvalho:
yes that is another reason why i say it was crazy talk on my side...

i think it wouldnt work...

but i am not sure...

one thing is sure... only way to make it work is using a s1 server sign it like sim lock is unlocked...
[Sony Xperia P, U, Sola, Go] thanitos:
Like I stated earlier in the thread this has been looked at before with no success for the ion
[Sony Xperia P, U, Sola, Go] Arteni:
I love my T, but I think it's better to buy a S3 when you are in carrier (without bootloader).

Sony Xperia T - Stock ROM - Firmware 7.0.3.195 - Nova Launcher Prime 1.3.4 - Holo Locker - Rooted soon.
[Sony Xperia P, U, Sola, Go] Gabe.INc:
Does it worked for you? you unlocked your bootloader status and sim lock?
[Sony Xperia P, U, Sola, Go] pcarvalho:
ofc not... we all working on same...

bootloader is not unlockable... just had a idea... but if the server that unlocks need a signed TA... it will not work...

i said this some time ago... im afraid only method... if it does work one day is via s1 server...

hope someone proves me wrong :)
[Sony Xperia P, U, Sola, Go] nanoteam:
xperia s owner

hi ... why don't try to make TA of an bootloader unlock = yes ... bootloader locked to work with another IMEI ... and unlock it in the phone with fastboot ... i think it's easy that why ... but may it will unlocked with the source phone code ..
[Sony Xperia P, U, Sola, Go] thanitos:
Because the TA needs to be signed, any changes and it is automatically unsigned. Just putting in a TA from another phone is a disastrous idea.... On top of that, if the TA is also signed to a specific device you'll need to address that problem as well.
[Sony Xperia P, U, Sola, Go] nanoteam:
no

it will be signed with IMEI .. or encrypted IMEI ... it's simple than unlocking the TA file because ithink it will need to modifie bootloader ... but imagine you find the IMEI encrypted you have just to change it and flash the TA .. you can acces to the fast boot and you can unlock it with the old fashion method .... i hope ....

[Sony Xperia P, U, Sola, Go] thanitos:
I warned you guys multiple times before this thread got past page three you ran a high risk of bricking your phone but some people claimed I was wrong.... Get your phone replaced through the contract company they can't prove you did anything since its hard bricked so they'll send you a free replacement. this is what bricked my ion messing with the ta doesn't work and isn't as simple as changing some code
[Sony Xperia P, U, Sola, Go] pcarvalho:
just so full story is known... comnic5 bricked it back in

october

anyway this is not for "normal" users...

i messed around with my TA a bit and i did not brick my device.

im sorry for those that did brick it was not the case here in this thread.

to my knowledge not one person bricked there device in this thread (be it from a modded TA file made by OP or Me)!

so please stop talking about it

there is always a risk, and believe me i know about it.

but now lets get back to what really matters

brainstorming on how to do this...

if its even possible (im out of ideas, i must confess)

cheers

Need Help

Hi guys,,

I just joined to this community and still very new in Android world. I have purchased a SONY XPERIA GO ST27a from FIDO canada and till right now I can only using my phone as android wifi device rather than a normal smartphone as I am still on my vacation in my hometown Indonesia till next 2 months. I am very frustrating till now because I can't unlock this phone. Anyone know how to solve this problem?The phone is not allowed to customize the bootloader and I have had to unlock it by a third party service but it wasn't successful. So guys please help me!:(

Thanks

I can confirm,bootloader is unlockable by two ways.

1. Replacing motherboard

2. Replacing bootloader

3. Modifying TA with mods and then unlock it with S1 server with will calculate new sign key,this could only work if S1 server does not signed TA to work.

Also everyone who wants to know I bricked phone because I try to replace bootloader.
[Sony Xperia P, U, Sola, Go] pcarvalho:
so no. 3 u mean... if s1 server doesnt check prior to unlock if the TA is signed it might work?

anyone knows if its checked? im guessing it does...

cheers

thanks for all ur efforts, hope u get ur device back soon...
[Sony Xperia P, U, Sola, Go] Galcactus:
Wouldn't it be possible to instead of replacing it completely, simply place an alternative one on the sd card and then change the boot from sequence so that boot loader is loaded in instead and the one in the phone is skipped? I've been done on one of the galaxy devices so it's possible, and if the raspberry pi boots off only an sd card and nothing else it is possible, surely? (I know with r.pi it's different, but still...)

Click the thanks button if I helped!

Sent by G.L.A.D.O.S.
[Sony Xperia P, U, Sola, Go] hydo1:
This is probably the most elegant solution, however you are still going to have to edit the boot sequence somehow in order for it to check the SD card for a bootloader.

Can this be done using bootstrap? As far as I know the Motorola RAZR does not allow boot loader unlocking but you can install custom ROMs to the data partition/SD card and boot from that, though I don't have any experience with this so I don't know the limitations.

Also a phone that a carrier has locked down is a very different kettle of fish to a Rasberry Pi, a device designed specifically to be hacked that does not have to fulfil any evil ways of a carrier monitoring you and fearing that you may remove their crapware and whatever logging software that they have installed for you.
[Sony Xperia P, U, Sola, Go] Galcactus:
Here's the link for the sd card bootloader on the galaxy devices:

http://xdaforums.com/showthread.php?t=2061437

If somebody were to get in touch with the devs responsible for that break through (Adam outler and rebellos I believe?) Then they might help us. I've written to a lot of devs about this bootloader issue that we have and very few replied to me, so in case it's me offending them, would somebody else care to ask these guys instead of me?

Thanks!

it does, if you ahve updated your software of setools, but there are some restrictions on the s1 server wich is offline

about opening the phone, if you are searching for the jtag pins, if is what i think u are asking for, i have tried and searched it for use it with my riff and nothing... it seems last xperias ont have the jtag port

about changing the boot.oader, i guess there is the ta and all things about the phone right?

good luck ^^

I got another idea but it might be dangerous,backing all partitions using dd and then flashing it to new phone, this should give phone new IMEI and should simunlock it also.

What do you guys think?
[Sony Xperia P, U, Sola, Go] josie87:
Sounds promising.

Isn't changing the imei illegal in some countries? Or would there be a way to change it back once the process is complete?

[Sony Xperia P, U, Sola, Go] XperianPro:
Well you simply backup your partitions and then flash it back.

Making script should speed up process a lot.

And yes it is illegal but really wont cop come in your house and check what IMEI your phone have.
[Sony Xperia P, U, Sola, Go] hydo1:
Surely you will be able to restore your IMEI after anyway once fastboot has been enabled(?)

Has anyone had any thoughts about something along the lines of Bootstrap or Safestrap that is used on Motorola Devices with locked bootloaders?

http://blog.hash-of-codes.com/how-to-safestrap/

Obviously this is for Motorola devices but I wonder if something similar could be the solution to our woes.

Thanks, I just did it with my LWW. I can absolutely confirm and recommend this. The phone was a branded one from Vodafone Germany. BL unlock allowed: No. The Software changed that to Yes and even unlock the BL. I had to pay for the service, but it was worth it. The LWW now runs CM10.

The procedure is like this:

1. You are shown a video how to remove the sticker inside the phone

2. under the sticker are some pins. The video shows you wich one to pull on ground

3. with the pins shortened the phone is connected to the pc

4. remove the shortening

5. Software does stuff, I didn't make a screenshot but I remember something like "repairing TA"

Maybe this helps.

[Sony Xperia P, U, Sola, Go] josie87:
Let me tell you a story about asking for unlock codes:

My second phone is a LWW (girlfriends phone). She bought it at Vodafone online shop in Germany with no simlock for the full price. She complaint about her phone beeing slow. I said: no problem, your phone + great work of cm = great performance ;). I went on the Sony unlock site and then: bam! Unlock Allowed: No.

Ok, I thought: "go to Vodafone store, explain it - they will help you with that.". So I went to the next Vodafone store. They just didn't understand what I'm talking about, but they gave me the number of a hotline. So I called them. After beeing in line for half an hour, I talked to a technician. He also had no idea what I was talking about. And he couldn't help me anyway because I didn't have a customer number. He said I must go to a local Vodafone store.

So I went to another store. I explained my problem to the first guy. He understood, he is here at xda, too. But he said I got to talk to his bos, cause he is new. So I talked to his boss, he didn't understand and was a nasty A55HOLE. He gave me the same number I recently called. I just thought: "screw you!".

Ok, I thought, if there's anyone who is able to help you, it's Sony. So I called them. They said, bl unlocking is only for devs and that I have to go to the store where I bought the phone.(Vodafone).

I wrote an email to them, saying that I'm starting to be pissed off. A nice guy called me, explaining me in detail that he has no idea what I'm talking about and that they will neither help me, nor give me a refund.

I gave up, I thought when I go on with that - I will simply loose my mind.

Yesterday I saw the method with wotanserver mentioned. I payed, downloaded and followed the instructions. Now I have CM10 on that phone :).

To sum it up: in Germany you might not expect any help from Vodafone or Sony with that. At least that's my experience. Wotanserver works, but not for every phone.
[Sony Xperia P, U, Sola, Go] thanitos:
I was under the impression we were discussing SIM unlocks not bootloader unlocks. The guy that bought the phone wants it off the network it's locked too so SIM unlock would apply
[Sony Xperia P, U, Sola, Go] josie87:
The bootloader and simlock are only a bit related to each other, as far as I know a simlocked phone always has a not unlockable bootloader whereas a phone with no simlock CAN have a locked bootloader. But removing the simlock doesn't necessairy remove the bl lock.

But,can we make a stock sign for custom kernel! ( custom kernel+ stock sign )

Sorry for my questions! ^^
[Sony Xperia P, U, Sola, Go] thanitos:
The kernal is loaded after the bootloader you can't touch the kernal unless you can fast boot which pauses the phone loading the kernal and such so you can make changes to it, I think thats how it works I'm not 100% sure
[Sony Xperia P, U, Sola, Go] Llumex03:
Think about the easiest way

Hi guys.

This is my first post in this site, however i'm seeing this thread for 1 month ago. Now let me explain.

I read different opinions but i think we need to know how PCC and FlashTool can send a firmware without brick our mobiles. When you "repair" a phone with PCC, PCC downloads the rom, (for example: ST25i), and then from this downloaded files you can make a .ftf file. Probably PCC signs the files with a generic signature or something. Remember you can select your phone without connect it.

What does FlashTool to make .ftf files probably signed?

This is strange bacause we know the solution but we don't know the method or steps to get the solution.

Thanks and greetings ;) .
