Xperia X10a Without Service - XPERIA X10 General

Hi!
I got an X10, but I had problems with the SIM.
It is, that when I put the SIM, start the device normally, and it shows "No Service". Flash the latest firmware through SEUS, and still the same. I thought it might be bad flash and lost their IMEI, or something, but at least to check your IMEI by code * # 06 # My IMEI is no problem.
Any ideas?
Cheers!
PD: Sorry for my English, Google Traductor that helped me a lot

Couple reasons it might not be working, not enough info about the phone....
1) Wrong network and not sim unlocked?
2a) Your X10 went through a bad bootloader unlock.
2b) Read this and this
2c) download this to check if it is sim-locked/unlocked. Note simlock / bootloader status
Report findings back here so someone can help you further.

I went S1tool status, but apparently nothing more than bad news
The device was going to be flashed, but the person failed in the attempt. I passed him for settlement, but I know that you can recover

Great, so you can easily unlock via setools, or some people actually had success relocking then unlocking a couple times using different qsd / setool unlock mentioned in above links. Easiest way is going to setool website. I also recommend EWjet kernel and rom combo from my xperiance

setool2: sim unlock service. look at your attachment, there is a link to it on S1tool. Also can go here and ask question to the_laser about sim-unlocking your phone the correct way.
After correct sim-unlocking, you can unlock bootloader and your phone will work on any GSM network.

Unlocking Vs. Debranding/Flashing Vs. Rooting -- Clarified

Hi All,
There have been many confused members (especially the noobs) who do not understand the difference between unlocking and debranding so I wanted to start this thread to clarify this matter once and for all.
Debranding/Flashing: : This is when you flash some firmware other than your original operator's FW. For example, if you have an AT&T or O2 branded X10, when you flash/debrand generic fw (or any other fw of your choosing) you simply get rid of the "branded" software pre-loaded on your phone. Hence, the term "de-branding". This does not mean that your phone is unlocked. You will still have to use your original operator's SIM card, like AT&T or O2, to use your phone EVEN AFTER flashing/debranding your handset.
Unlocking: This is when you "network unlock" your phone and are able to use it with any GSM operator you choose other than your original operator. For example, you have an AT&T or O2 branded X10 and you want to use it on T-Mobile US or UK, can you do that after simply flashing/debranding? The answer is NO. Why? Because your phone still requires a special code to be entered before it becomes network unlocked. For further reading, please go here.
Rooting: Rooting is a process that allows users of cellphones, and other devices, running the Android operating system to attain privileged control (known as "root access") within Android's Linux subsystem, similar to jailbreaking on Apple devices running the iOS operating system, overcoming limitations that the carriers and manufacturers put on such phones. Rooting makes it possible to use custom versions of the Android system such as CyanogenMod, supporting features unavailable in stock ROMs. It also allows for newer versions of Android not supplied by the original device manufacturer. Source: Wikipedia
Debranding, unlocking and rooting are mutually exclusive.
FAQs:
1. If I flash to generic firmware using Bin4ry's flash tool, will I unlock my phone?
No, you will simply debrand your phone but, you will still need to get the unlock code.
2. If I debrand my phone and then unlock it but, I would like to go back to my original branded firmware, will my phone become re-locked to that network again?
No, once you unlock your phone, it will remain that way no matter what firmware you flash in the future.
3. How do I know if my phone is network unlocked?
The simple way is to pop in another operator's SIM card, for example you have an AT&T branded X10a, then you can use a T-Mobile SIM card. If your phone reboots and you do not get a "enter code" screen and you see that you are connected to the T-Mobile network then your phone is network unlocked and can be used with any GSM operator.
Another way is to go into the hidden service menu. In the lock screen (the one with the swype animation) press the following sequence of buttons (Home, Back, Back, Home, Back, Home, Home, Back). If you are on 1.6 replace Home with Menu. Then go to service info --> SIM lock. In the top line, if you find this [X] Network 10, then your phone is locked. If you find this [ ] Network 10, then your phone is unlocked.
4. How can I get my unlock code?
There are a few sites from which people were successful in getting their unlock codes like MobileInCanada and CellUnlocker. There is also a thread by Xda-member "Lancez" here who can provide unlock codes for a fee. Currently, there is no known method of unlocking your phone for free.
I hope I have clarified this matter for everyone.
this should clarify the unlocking scene

I hope so!
Well, thanks for the info; however, what I wanted to know was the "technology" behind the lock codes which can survive after flashing. What do they use to keep them safe? In which part of the software is the code stored? or most likely, the code should be hardcoded then.

I think there was a typo above. It is more like 9% of the time. Lol. Unless you type exactly word for word the results often send you to completely different forums, even though it says "search this forum". Test it yourself... Search using XDA search button and then do a Google Search. Google is much better, for me anyway.

I don't think that's correct. My x10 has 0 next to Sim but it's definitely locked to t-mobile. There's an X in the box next to where it says network for locked phones.

The [X] means it is locked. The 0 means that you have 0 attempts left to enter the unlock code. You get 10 in a new phone. Did you enter the codes too many times or did you buy your phone pre-owned?

People with bootloader unlock allowed:no [how to unlock it] (GSM ONLY NOT CDMA!!!)

Hi people I didn't know whether to post this in the android development forum so I posted it her.
Soooooooo.......... For people that are confused when they dial in *#*#7378423#*#* and they find out that it says boot loader unlock allowed:no.
I am just going to clarify a few things. Don't worry its not the end of the world you can still unlock your bootloader. thats the good news. The bad news is that it will require you to pay some money. You are probably having this problem because:
a) Your phone is sim locked
b) You are using the R800at or R800X if so then get out of this forum!!!!!!!!
So to solve this problem you will have to sim unlock your xperia play although, you MUST use a software that uses the phone's testpoint to sim unlock the phone e.g. Omnius any other unlocking method used that does not use the phone's testpoint will NOT work.
Once you have done that taaa daaaa!!!! now when you go into the service menu it should say bootloader unlock allowed.
Although your not done yet, now you will have to unlock your bootloader this is FREE to do in fact sony ericcson offers the instructions how to do it themselves. Here is the link to the instructions:
unlockbootloader.sonyericsson.com/instructions
Since i'm a new member xda not letting me put in any hyperlinked links.
Make sure you know the risks of unlocking it!!!!! Enjoy!!!!!!!!!

No i'm just saying this because the requirements to unlock the bootloader on the se website says make sure it says boot loader unlock allowed: yes
I haven't tried using fastboot or anything this was just for people that were stuck here in unlocking their boot loader i was just sharing that it changes to yes when you take off the sim lock and i know it is possible to unlcok the bootloader of it even though it says its not the steps i have given does unlock the bootloader as i myself have tested it on my friend's o2 locked phone.
On my phone it says
Rooting Status:
Bootloader unlocked allowed: Yes
so do i have to pay money to unlock it or what?
I'd like to try and root it.
My phone was originally locked to O2, I got it sim unlocked from them and i still have bootloader unlock allowed:no ...
You have to do TEST POINT METHOD!
This Unlockes your Sim lock i think as well as fastboot which you need to unlock,
sim locked phones are branded and have Blocked Fastboot with a Unknown Patch the Bypass is test point method however you Must Not ever Update VIA PC companion or OTA Doing so = a brick.
If you want to pay up the money go to Aljendrissimo he has proven 12,000+ people with SE phones Bootloader Unlocked with OTA fix ans Pc companion which means you can have the ICS update but its got the sony suite

If it says bootloader unlock allowed:yes then you don't need to pay to unlock your bootloader just go to the link I put up and follow the instructions.
Also,on the other comments yes this does indeed has to be done through test point method which is very easy many sites do this, I used cellunlocker.net's se unlocking software to unlock mine. I also checked yes by doing the testpoint method it also,gives you the option to unlock the bootloader I do recommend omnius because you can by a android unlock liscense for just 10 pounds but to clarify you DO need your sim unlock to be done through test point so you can be able to unlock the bootloader

It has been broken down for you on the first page, if you do use the test point method then you can't do OTA updates which means, you can't officially update your play when offical updates come out but it's not all bad as you will be able to flash the offical update with a FTF with the flash tool. It is recommended to use the test point method.

No I don't think that is true because you cannot do OTA updates only if you have a locked boot loader i'm not sure where you got your info from mate but i'm pretty sure all the test point method does is sim unlock your phone and does something to make the bootloader unlock possible and that is what I m trying to find out- what it does to make the bootloader show yes .
I have confirmed with various trusted sources if you are still able to update even if you are sim unlocked with test point and they are saying yeah only if you haven't unlocked the bootloader.

2. If no, then will I be able to unlock the bootloader using the method given in this thread http://forum.xda-developers.com/showthread.php?t=1302423
I can see that there is a lot of community support for this phone and I would love to root it and install custom ROMs on it. Please clarify me on the above points.

Hi Karthik,
I have also bought through Ebay.
1. Does GB 2.3.4 come with an unlocked bootloader, so that I need not do anything to unlock it myself?
A) If the phone is sim unlocked than most probably it has unlocked bootloaded. You can check this by restarting the phone, if UNLOCKED is displayed at the top during booting, then its bootloaded has been unlocked.
2. If no, then will I be able to unlock the bootloader using the method given in this thread http://forum.xda-developers.com/showthread.php?t=1302423

Thanks for the reply. I do not see the UNLOCKED text while booting up. so probably the boot loader is still locked.
In the thread which you used to unlock, there is no step to root the phone after unlocking the boot loader. After unlocking, the next step is installing a custom recovery. So how do we root it? I don't want to explore multiple threads as the instructions are confusing. Please help!

This is NOT TRUE..
Sim Unlock and Bootloader Unlock are different.
Bootloader Unlock will allow you to install any other firmwares. This will display Unlocked message on bootup.
SIM unlock will allow to use other carriers SIM card other than Orginal carrier.
For Ex. if you have ATT US Atrix, you wont be able to use it for other networks until you perform SIM unlock. This will not display Unlock message on bootup.

2. The same page has a method to unlock the bootloader. In that, it is mentioned that the SBF flashing need not be done if the phone runs gingerbread. The steps direct us to run the unlock command if we're on GB. But on all the methods here in XDA, the SBF flash method is mentioned even for GB 2.3.4 phones. This thread for example. which one to follow?
3. I'm planning to follow the above thread, but in that thread, there is no step to root the phone, after unlocking the bootloader. The next step given there is to install custom recovery. So what do I do to root it?
Please clarify these questions. Thanks in advance.

1.Rooting a phone is different to unlocking the bootloader. So yes when you root the boot loader will remain locked. Unless you use a script which automatically roots and also unlocks the boot loader.

Atrix 4g Unlocking and Upgrading.
Hi there guys!
I am planning to buy Atrix 4g through Ebay.
The listing on ebay says that the phone is unlocked?
I am pretty much new to all this and all that I wanna know how do I get rid of Motoblur without putting any custom roms.
PS I heard that Moto has released gingerbread but I am afraid if I update with Motorola Software Update, it will re lock the phone?
Hi
I use atrix in mumbai..
The phone which you will get from ebay will be sim unlocked...that means you can use indian sim cards on the phone
To get rid of all blur software i would suggest you to install a custom rom from the forums..for which you will need to unlock bootloader root your phone and install custom recovery
Youll find tutorials for these in the forums
Cheers!

[Guide] Unlocking bootloader on operator branded phones via omnius

Hi all,
If you have a locked bootloader on a branded phone (for example, from Rogers) normal BL (bootloader) unlocking methods will not work. Fortunately, there is a way to unlock your bootloader - it will, however, cost money.
I have a very good experience with Omnius. The program is simple and fast, and the whole process of unlocking the bootloader took less than 3 minutes. Here is how I did it:
go to Omnius downloads, and download Omnius for SE.
Install it. The installation includes all the drivers you need for this process.
Now you need to purchase credits. You can use any of the re-sellers listed here. I personally used GSMServer single unlock licence for 19 USD.
After about a day, you will get an email with username and password. This is your new Omnius account that has enough credits for one unlock. (I am not sure if it is only for BL unlock or also for SIM unlock.. It definitely works for BL unlock though.)
1. Now start Omnius. In the upper left corner choose your SE model.
2. In the server settings, enter the username and password you got from the reseller of your choice.
3.Next click on "Unlock", and select "Unlock bootloader". A picture guide appears that is super easy to follow - it tells you where the test point is, what to do, what to press, when to remove battery, everything. Few seconds later, your bootloader is unlocked!
Hope this worked for you guys!!
(I am in no way affiliated with Omnius, or any resellers listed on their website. I am simply summing up my experience, as I know that BL unlocking for branded phones is a bit of a problem. I hope I did not break any XDA rules by posting a guide involving a paid service!)
Does it void warranty ?
Sent from my LT15i using xda premium
Yes it does. But I should have mentioned - this method LEAVES ALL DRM UNTOUCHED, so that by simply relocking BL nobody can find out you did anything with your phone I had my phone in repair 3 times, every single time with unlocked bootloader. I had no problem so far
I just rooted. Does it void warranty instead ?

Rooting doesn't void your warranty. Only unlocking your bootloader voids it.

Don't matter, Sony don't recommend rooting, but it will not void warranty.

Best choise!
Does this require any special cable to be used for the test point method? I have seen people just use a paperclip but then I have also seen people use a cable attached to their USB cable, so I am not 100% sure on what I need to use.

Nothing special; a paperclip will do.

Ah that's great! thanks one other question, is it the same method for the arc s? is this method done 100% by me and not by someone connected to my computer? like I have seen some people do.
So what do I need to do specifically to unlock it? Will I have to open my phone up or do I just plug my USB cable in? Also will it be unlocked for good? If I update or downgrade firmwares will it remain unlocked?

I think I can answer the last two questions but someone correct me if im wrong xD you need to open up a tab on the back of the phone underneath the sim card holder to reveal "test points" you will then use them to put your phone in a certain mode which allows you to unlock the boot loader. im also sure that the boot loader if separate from the firmware so once you have unlocked it then it is unlocked for good. im not 100% sure how to do it though because I have seen so many different ways and its just got me confused haha.
Is it ok/enough for the process? http://www.gsmserver.com/shop/gsm/omnius_one_day_full_license.php

Hmm I am not sure. I think you need also some credits for the unlocking.
my xperia arc s ic carrier branded (sim lock) and in service meni is bootloader unlock allowed: no ... can i unlock my bootloader with omnius without sim unlocking it and will i have enabled fastboot
Yup, that's what this does. It will unlock the bootloader on your phone.
Btw I feel that you should have fastboot working even now without unlocking.
why do you feel this
Further unlocks
Hi there,
I have one question.
I have read a lot of threads about unlocking the bootloader of branded phones, and I haven't found an answer for this question.
Let's say I buy my credits and all, and then I go and unlock the bl, wonderful, but then let's say that I need to send my phone to warranty. So I lock the bl again. Then my phone comes back and I want to unlock the bl again, do I need to buy credits to do it again? Or will the credits I bought on the first time will suffice for the same phone over and over?
Thanks btw for this thread, helped a lot.
Thank you!

locked and unlocked bootloader

I wanna share my experience with my locked bootloader.
I tried once to unlock and install a "just 4 unlocked" rom (2 roms actually) but the radio system didn't work (no phone, no wifi, no gps).
I got back by flashtools, i installed a rom 4 locked rom and i tried once more to unlock the BL. I installed CM10.1 and now everything is working perfect!!!
I got just a question 4 you: why does some xperia z has the BL locked while others unlocked?

All Xperia Zs come locked from the factory. Most can be unlocked to flash custom roms. Some are permanently locked because their carriers are iffy (to put it nicely), but those are the minority.
Keep Questions in the Q/A section, not in General.
And No SONY device comes with locked Bootloader always. All are locked by default from the factory. Among which some can be unlocked and some can not because the Carrier.

Ok, but my gadget showed "no in Service info > Configuration > Rooting Status > Bootloader unlock allowed (and in the post about unlock BL they says that if it's "no" the device cannot be unlocked).
Thank you
PS: How can i move the 3d to Q/A ?
That is what I said.
All the Devices are locked bootloader by default.
Bootloader unlock allowed= Yes -- This means you can unlock the bootloader by following regular method.
Bootloader unlock allowed= NO -- This means you can not unlock the bootloader. Because of the Carrier issue i believe.

thx i got it.
But mine showed Bootloader unlock allowed= NO but i was able to unlock it after 2 try. I think every one following my procedure might do it.

I think you will always have been able to unlock yours, you just didn't do it right the first time.
So are you saying you have a locked boatloader and can install. CM10????

did you root it and put a different ROM on there? the status might change say no but you can still unlock it. Simply put if first time you boot up your phone and it say Unlock bootloader = NO, then dont try to unlock it. When you root and flash a different rom that status might change to yes but in reality it still a NO

Eventually a right answer.
I was told the same. But i love to risk "playing" with my gadgets. So when i bought the xperia z through a carrier I saw the first time i boot up that the phone Unlock bootloader = NO (about 5 minutes after i bought it from the shop, so it was "original as the carrier made it).
I didn't care it and i tried to unlock. I installed a unlocked bootloader and rom and i had all that problems with the radio stuff . But the second time, after i recovered it by flashtool and a sw from sony (i don't remember the name) I was allowed to unlock it and install unlocked stuff. Now I am with Paranoid and I am so happy

same here... unlock it. install all the unlocked stuff. Radio might don't work. . Get ur phone back by flashtool and sony sw (i don't rememmber the name). The sony software will say u after a while u r not able to recover the phone cuz you are using some some software that is not sony. Don't worry and install another time a rom unbranded by flashtool.
now unlock the phone again and install everything u might like
There is only a problem with the twrp recovery, so use only the other one

Can anyone else confirm this?
Thanks!
Very interesting... Im waiting the confirmation from sony to pick up my phone without cost to change the fastboot to yes, but if this is true and someone else could confirm this method il do it tonight!!!!

I think if you want others to try what you've done, (and it is interesting if we can unlock bootloaders this way)
then you may want to highlight which steps you did in more detail.
Which roms did you try to flash that resorted in no radio functions?
which rom did you try to flash with flashtool? which version of flashtool as well?
Did you do anything else?
I somehow doubt engineers would make an oversight as big as this one.
But fingers crossed nevertheless.
+1 for a detailed description of the steps you took. This could be huge!

Indeed, this move would make the XZ much more attractive for buyers which have the bootloader locked from the carrier.
