Unlocking bootloader killed my C1905, help please!... - Sony Xperia M

Hi everyone
I wanted to try going from the stock Android 4.3 to cm12.1.
My phone was bootloader locked but unlocking was allowed.
So I followed the process on the sony website and got the unlock code and entered it.
Phone then refused to restart, stuck on booting screen.
Eventually using Flashtool, I found a stock rom and reflashed that, still wouldn't boot. Then I relocked the bootloader and now it boots again.
However, it now says sim card is invalid and refuses to let me join the phone network (I'm in Malta, using the Go network).
Also, I'm now unable to reunlock the bootloader as it says failed when I try doing so using fastboot and says it cannot be officially unlocked when using flashtool. Worryingly for me, in settings it now says "no" for unlock allowed (it used to say "Yes").
So now, I've got a phone that otherwise works normally again except that it doesn't actually work as a mobile phone! Please help me someone as Sony have already refused to do anything to help, their customer (dis)service people simply point out that once you unlock the bootloader - even if that itself causes the problem - they will no longer help you. Cheers, thanks Sony, no way will I ever buy any product from you ever again!
What a crap day...

i think you have missing something after unlock bootloader, and you can't give any wrong or false to sony. because you're do this with your vault and you're is vault your warranty. and sony have give you a warn sign before do this, and you accepted because you do it.
so no any vendor problem if you fail or your device is bricked.
after unlock bootloader, you need to reflash your stock rom again and do a full wipe data and cache from flashtool before flash any rom. after wipe and flash you can check your device is boot up perfectly without any problem. you only missed that. try to reunlock if still can, but try to unlock your bootloader using flashtool too.

Well on Sony's site it also says that any repair will be chargeable once you do unlock, so I would have expected them to have done something at a charge not to totally refuse to help at all. I accept what you say but I DID follow the instructions exactly, I unlocked the bootloader and rebooted it as instructed and from there it went wrong - refused to boot.
Anyway, I have tried several stock roms including even using the Sony tools and letting it do a "repair" reflash, all to no avail. "Sim Invalid" is what I'm left with and what I have noticed when flashing every stock rom with flashtool, what is missing from the "Wipe" list is cache, the only option there is "USERDATA". Is there something wrong with the flashtool perhaps?
Even when I relock the bootloader using flashtool (which I seem to need to do every time even after flashing a stock rom) it still seems to regard the phone as unlocked, or at least when you go the "BLU" screen it shows only the option to relock each time. Something has definitely screwed up here.
I got a UK stock rom via Xperifirm and used Flashtool to create the TFT from that. Still no joy. I'm assuming something is wrong with the sim lock, somehow, but how to fix this? I'm realising that reflashing stock roms doesn't totally return the phone to factory condition, so what am I missing here please? Is the phone totally stuffed now or is there still some way to repair it?

Ok so further to this, I just gone into service menu -> Sim lock and I see this:
[x] Network 0
[x] Network subset 0
[x] Service provider 0
[x] Corporate 0
[x] SIM 0
So is the phone locked or not? What does the x mean? The phone was previously fully sim unlocked as I bought it without a contract from Amazon. Is there a way to fix this please?

help me please
i have xperia m, after unlocking bootloader it stuck on bootlooping, i have not enable usb debugging...any way to fix it?

[Q] R800a can not OTA update or enter fastboot, root problems? mode.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.
R800i, Android 2.3.3, Kernel 2.6.32.9-perf [email protected] #1, Build number 3.0.1.A.0.145
Edit: Title should be "Can not OTA or enter fastboot mode, root problems?"
Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.
Sent from my XPlay using XDA App.
Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.
Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it
It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter
I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

If you need help with unlocking your phone contact Alejandrissimo he does Unlocks
I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?
Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps
Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

Sony Xperia S Bootloader unlock Problem

Hi all,
I've got the Sony Xperia S and unlocked the bootloader and rooted it once and flashed it with the AOKP, but that didn't work, so I tried the Cyanogenmod 10.0 (Jelly Bean). In summary I think it was the wrong Combination of kernel and custom rom, because it didnt boot anymore and got stuck at the logo.
So I closed the bootloader again and installed the official stock rom from Sony, and all got fine, luckily.
With some more reading into right forums and better knowledge I got the right custom rom and kernel and tried to unlock the bootloader again, but suddenly it didnt work.
Message: Failed (remote: oem unlock 0xF (und noch mehr F) )
I did all with fastboot and the right adb drivers, the phone is installed correctly.
Yesterday I asked for my problem in a shop and the guy said, that the bootloader of any Sony device would close completely, if the (right or wrong) unlock code is used for too many times (like the limit of 10 times).
If he's right, I've got a big problem. But can't I open it with an alternatvie method? Or is there just any mistake?
Thanks for any answer
Chriszo
i dont know, but ive already relocked and unlocked many times without error ,
try to do it again and be sure to input the correct 0xKEY
CM10 contains it's own kernel so could never be a wrong combination of rom and kernel. Did you actually unlock the bootloader or just root the phone? Sounds like your bootloader was locked and you were trying to flash still
Sent from my 4.2.2 Xperia S via Tapatalk
Thanks for the answers.
I don't still know what constellation I really tried to instal the kernel and firmware, but I think it was an advanced stock kernel and then the firmware of the aokp. After that I tried the Cyanogenmod, but the device just didnt boot, there was only the logo.
I remember to have taken the kernel named ics17.elf and the advanced stock kernel with the official 4.0.55 build number.
The the device was rooted and the "sd card" was not wiped, but the data of the apps were deleted.
So the bootloader was open because the kernel can't be flashed with a locked bootloader.
After that I flashed the aokp and then the cyanogen mod.
Because of no booting I relocked the bootloader and installed the official firmware from sony.
Since then I try to unlock the bootloader with this damn error
I try to unlock with another computer. Maybe it work and its a simple solution. To unlock my bootloader i need to use my wife´s laptop.... i try in my compputer many times, install drivers, uninstall, and a lot of tricks but fastboot give me "error" all the times... lol
I just chatted and called with the Sony support (nice to hear great english at the phone ) and again got to hear, that they aren't able or allowed to give any information about the bootloader because of the possibility to loose the warranty of the phone.
I dont know really where my problem is but I think the code is not working any more, although I cant imagine of that
Is there any other way to do that? Or do I just do a stupid mistake ???
Thanks
Chris

No no no!
Another guy on xda did it with FlashTool on locked bootloader. I was able to do it until the logo...
Apparently you only can flash roms I think, not?
Anyway Sony supports Open Developer Community as well, they give you info about bootloader here:
unlockbootloader.sonymobile[dot]com
No, I cant flash any rom, therefore I need an unlocked bl. And the stock rom from sony isnt available in the internet, just with the Sony-mobile-update-service.
Well, of course I tried the way Sony dicribes on this webside, as explained below -.-
Got the solution ??
Hey I have the same exact problem and i did the same things as you did ... did get a solution?? please inform me if you did.....

[Q] Help me unlock the bootloader of Xperia m dual!

I'm using Xperia m dual c2004.I tried to unlock the bootloader. Several times using the procedure given in the Sony developer, did everything correctly. But the phone goes into a bootloop after which the only option is flashing the stock rom.
I tried unlocking the bootloader the otherway by using flash tool but it doesn't have my phone's drivers. And the link to download them doesn't work anymore (found it in a thread)
The are no roms for lb for my device (plz tell me if you know any)
I checked my bootloader status by going into *#*#bla bla code then service tests and security And the service Status was active which means bootloader is locked.
When I go to service menu and config my phone's rooting status is showing bootloader unlocked.buti don't think it is ul but it just has the Permissions.
Please help me I'm not able to flash roms because of this.

When you successfully unlocked bootloader you should go to bootloader mode with key combination when restarting phone and install custom recovery. Naturally without loaded drivers in computer it has no sense to try it.

[SOLVED] Help to unlock Z5 Premium ?!

Hi there guys! I've got Xperia Z5 Premium (as far as my PC recognize it as such).
It is probbably with locked bootloader, cuz in fastboot it gives me error : <remote:failed command not allowed>
BUT i do not have access to the menu. I found the phone in one mountain near a hut, so far i decidet to try flashing it, but it seems bootloader is locked. Phone is locked also with pin code.
The usual methods i found need IMEI, which i do not have. If i open it, is tehre IMEI number ?
Is there any way to flash it or get the IMEI?
PLS guys, don't bother ****talking about stolen device or such... If anyone recognize it, come and get it.
SOLUTION that worked for me : https://forum.xda-developers.com/z5-premium/general/how-to-tottaly-unlock-xperia-z5-premium-t3585640
if you have find that device in a hut. its probably better to return to authorities! the owner might have valuable data in it! atleast try tracking down the owner!
however you can still flash the device via FLASHTOOL using flashmode / original STOCKROM only and you can keep the data also alive by just excluding wipes in the flash firmware area.
once booted try to find the owner info and return the device!
i
Hi. I work in that hut, it is in ski resort, so you can imagine how many people are going thru there. 2 months, phone was ON and connected to WiFi. No sign that someone is looking for it.
There is no owner info on the lock screen, so.... And where i live, authorities are worst than thiefs, so, that is not an option. As there is no IMEI or other info on the phone itself, i think it is unable to find the owner! Also it is foreign sim card in it, but noone calls or text.
EDIT: I've used both flashtool and fastboot, but no success. In flashtool it says "Your phone bootloader cannot be officially unlocked" , in fastboot > Failed(remote:command not allowed)
So, is this a one nice BRICK with clock on it ?!
Isn't there any way to force flash or unlock screen or bootloader ?!

you cannot just simply unlock the bootloader like that. you have to request SONY to send you unique keys and these used as password in order to unlock you bootloader! ( i.e. if the device is NOT SIMLOCKED from the origin country)
-- unlocking bootloader means LOOSING your DRMKEY/TA BACKUPS ,
please make your self aware of all the circumstances!
I have key to unlock bootloader from SONY. May be option in phone menu is restricted so this stop apps from flashing :/
I know about all circumstances.
So far i've flashed OEM rom, but now it ask for google account that was previously used on that phone, which is annoyng. Sony is copying apple or what ? Wtf happen with our android devices

it will remain mystery to me that how did you manage to have imei number of the device while phone was locked---- anyways
while device is open , goto dialer and dial *#*#7378423#*# then goto service info >>> Configuration and check "BOOTLOADER UNLOCK ALLOWED:" if it says NO then sorry, this device cannot be BOOT UNLOCKED. better to return it!
the previous google account prompt is because the old user data is intact. perform CLEAN FLASH , wipe EVERYTHING. (just tick the boxes as shown in the image (FLASHTOOL FLASHMODE , FIRMWARE SELECTED)
and a Big NO to sony copying Apple. and nothing happend to android devices! you can have easy go devices like huawei/lenovo/alcatel/(even samsung) etc. their stockrom can easily be xploited and kingroot supports various of devices under those brands. however Kingroot removed SONY from their website after Android 5.1 since they could not bypass SonyRIC from Android 6
I've got imei thru Flashtool, Emma, there it showed me Imei number.
This option with the code in dialer may be usefull with older android version, now it is unable to use it thru emergency call, since i do not have access to dialer itself.
I performed clean OEM flash thru Flashtool, wipe everything, but account lock is still there.
I do not know where to return it! It is foreign phone. I wait 2 months for someone to call or look for it. I work in ski resort and almost every day someone found lost phone. If i return it to police, they ouldn' do anything about it. Will sell it for 20euro probbably. I have friend in police department so i know what is going in there.

[Q] Encrypted data

Hi guys,
I just got Xperia M from my friend to install on it some custom ROM and etc. but there is encrypted data and I cant do nothing with it.
I tried repairing software with Xperia Companion, but I get UEUpdateFailed UE_2005 error and cant get past it. I tried also to enter recovery, but there's no recovery. Dont know what to do, cuz I need to check if I can unlock it.
Thanks in advance
Hi,
I can't figure out what exactly is giving you trouble, so you might want to be a little more specific. So I don't know if this is helpful for you, but:
First, there is no stock recovery on the Xperia M. As long as you don't flash a recovery on it, there is none. So you won't be able to enter that.
Next thing, Xperia Companion is a software to update or repair the stock ROM. So you won't be able to flash a custom ROM with that.
Just backup the data (if the data is encrypted and still needed, you didn't say what exactly is encrypted) and use flashtool to flash a ROM.
I'm not sure what you mean with checking if you can unlock it. The encryption? The boot loader? SIM lock? If you can unlock the boot loader (and SIM lock status too) you can check with the service number, so no need to flash it for that. Or is the device not even starting up because of the encryption?
So I dont really know if I can unlock bootloader of that phone cuz I need to "you should confirm that it is possible to unlock the boot loader of your device by checking the service menu. In your device, open the dialler and enter *#*#7378423#*#* to access the service menu" but I cant cuz of encrypted data. When phone boots up it ask me for password, but I dont know it. When I tried to use repair function to flash stock software and then the encryption would be gone it gived me error mentioned before. I dont know any recoveries or Roms that I can flash on locked bootloader. Any sugestions ? I want to flash newest Lineage OS at the end.
Is it possible that the boot loader is already unlocked? PC Companion is not working with unlocked boot loader.
You can also use flash tool to check if the boot loader is unlocked or not.
how to check that in flashtool ?
You switch off your phone, hold the volume down key, connect the usb cable, then it should be recognized in flash tool. Then you click on the lock. It should tell you the state of your boot loader somewhere there.
