Hello,
I am only user, so no detailed knowledge about Android. But I am able to read instruction, so I've flashed often ROMs and also Kernel without problems.
(BTW - nice forum - and thanks to all developers to give us the chance to modify mobile phone)
Last time after flashing CM7.22 + nAa-Kernel (I flashed without SIM inside) I had no GSM after inserting SIM-Card. All other functions works normally (in Stock-ROM only in flight mode - in normal mode it hangs).
After that I tried several things:
- PC Companion Repair - so flashing Stock ROM
- SEUS flashing Stock Rom
- Bootloader unlock
- Root again
- Other Kernel /ROMs
- Flashing Stock-ROM with bootloader
All time no GSM. Can I do anything else ? Can it be Software failure, or maybe random Hardware failure, happens just when I flashed....?
Has somebody an idea ? Or is it bricked ?
X10 MINI or MINI PRO?
Also, if your deviced was branded (I mean if it has some carrier's label on your phone or apps pre-installed) and supposing you unlock bootloader, the GSM gets disabled. When you flash stock, bootloader gets patched and you have GSM again, I think or you've lost it forever and you need to recover it with
Also please, post in the correct section, this is a Q/A thread.
A known quote from SpyderX
If the simlock certificate specified is SEMC SIMLOCK CERTIFICATE, or anything other than NOT RECOGNIZED SIMLOCK CERTIFICATE, or if you are sure you sim-unlocked your phone using Omnius, jump to step 3.
If the simlock certificate specified is NOT RECOGNIZED SIMLOCK CERTIFICATE, you can't unlock the bootloader of your phone. If you try, radio capability of your phone will be disabled (this has been reported to be untrue by a number of people who claim to have unlocked bootloader successfully with msm7227_semc.cmd).
Do note that the SIMLOCK certificate doesn't mean that you have/don't have a sim lock on your phone.

Note that radio capability is the GSM.

In fact, bootloader was never unlocked, it was backdoored patched, thus, when you flash stock the patch is replaced with stock "file" resulting a "bootloader lock".
Your argument is totally invalid. I had unlocked bootloader, flashed back to stock and bootloader was locked, I couldn't flash kernel. So I unlocked again.
I can confirm you are wrong, because I did many tests on bootloader locking/unlocking.
No offence,
Thank you.

I don't meant to prolong this out of place thread, but..
How do you unlock your bootloader ? When I unlock it using flashtool, I never got mine locked again, even after flashing back to stock rom / kernel using flashtool or SEUS as well... I can just flash another kernel after SEUS-ing it, without the need to unlocking it again. .
How can your phone locked itself again ?

I never used FlashTool for bootloader unlocking, always the old traditional way of patching bootlaoder with s1tools.
Unlocking with FlashTool might be the issue. I can't tell how to lock it again, I only know that this is due to FlashTool.

Hi,
at first so good news - phone works - very good feeling to write this !!!
I posted my problem in Q/A-section (sorry again for posting my question here first).
Roughly explained I got hints - so I flashed Stock-ROM again, then I relocked bootloader with S1tool, and suddenly phone works correctly.
I don't know what and when I did a failure with the result of GSM failure. But problem is solved. So thanks to all who has tried to help.

Hi there is it possible to relock the boot loader for xperia mini? I unlocked it because i tried CM7. Now I am thinking of going bag to original firmware. Any help is appreciated!
If relocating is not possible, what should one do to get as close as possible back to the original firmware, is it still possible to get official upgrades?

Third, remember if you are doing it with official method, you will never able to receive FOTA or SEUS update, you can, but only by flashing from xda.
So since we did the unofficial method, After we update through SEUS the bootloader is still unlocked?
I don't know about that. Since the service info still says bootloader unlocking allowed, I think the phone thinks itself as still locked. Flashing from seus might rely more on drm instead of whether the bootloader as locked or not.

when service info says Bootloader unlock allowed: true, that means that it the bootloader is locked, but can be unlocked at will
as many devs say, unlocking the bootloader voids the warranty and bricks the phone when doing FOTA or SEUS
but there's a flashtool out there for us that will take care of it

Yeah. I can confirm that my bootloader is unlocked but it still says 'Bootloader unlock allowed:Yes'
I thought at first I wasn't succesful even though it went smoothly so I tried flashing custom Kernel and it was succesful.
I want to know if in the future if SE release their ICS and we update using SEUS the unlocked bootloader remains because believe me, I don't want to go through the same process again, I got electrecuted several time because I don't have test points, just a clip and copper wire.

Hey guys.
Two days ago i have flashed back my SK17i to stock rom.
I updated from FOTA.
I didn't know i must relock bootloader before updating from FOTA, so i bricked my phone.
After 2 minutes of deep panic, i've flashed the relock .ftf file, but it won't work on phones unlocked with test point.
So, i found a way to relock bootloader and go back to stock. (On forums i didn't see any guide regarding the method to relock bootloaders unlocked by test point)
I've done in this way:
1) Flashed stock kernel
2) Flash the .ftf relock file
3) With S1Tool hit restore
The phone is now bootloader locked, without losing of DRM!

brov dont really understand dis, please break it down a little bit!
I just registered to confirm this method works. I foolishly allowed a FOTA yesterday and bricked my phone. It was unlocked via testpoint so the relock method didn't work, even though I tried it! I also tried flashing with S1tool with generic firmware and that didn't work. Then just out of curiousity/desperation I clicked on the RESTORE button in S1 and my phone actually started but was now locked again. I re-did the testpoint unlock this morning so now my phones fully updates and working with my SIM of choice.
I don't know if you need to do all the flashing as it may just be the RESTORE that does the trick. I definitely won't be allowing any OTA from now on. Lesson learned!
Just to confirm, so long as I do the update via PCCompanion or SEUS software I wont need to do all this?

You can't root on fw .62! You must flash back to .42 (use wotanserver) and then root. After that, update your phone by OTA (on the air update) to .62!
Completely untrue. You can root - read the posts.
In a nutshell, because posters fail to bother to read everything:
Copy Rootxperia.zip to the SD card
Factory reset (don't format the SD card)
Use flashtool or Wotan to install your version of 0.62
Use fastboot to BOOT (not flash) recoveryNeo.img
When CWM boots, install Rootxperia.zip
Done
(CWM in this instance is hot booted, not "installed")

This method works only with unlocked bootloader. By unlocking bootloader you loose warranty and some phones has no unlockable bootloader.
The OP has an unlocked bootloader... according to previous posts. My response reflects that.
Unlocking BL MAY affect your warranty... in practice highly unlikely.
Phones that cannot be unlocked are likely carrier locked which is a whole new moral ballgame. The desire to mess with these is dubious at best. Users intending to modify their phones should have unlocked carrier-free phones.

OTA update brick phones with officially unlocked BL. Since the ones unlocked via test point can use all official tools(PCC, SEUS) I believe they can also use OTA, since their BL's are patched.

With officaly unlocked bootloader OTA update not possible!
Some customers with unlocked boot loaders have experienced problems when they are accepting over the air upgrades (FOTA - Firmware upgrade Over The Air). For customers that have unlocked the boot loader, please do not accept any over the air upgrades. For additional information, check out the hints and tips from the community on the XDA forum.

Yes, that is official statement for BL unlocked via official way. Since those phones can't use SEUS or PCC because those programs can realize someone messed with OS, but FOTA is dumb and can't realize that, so she still try that's when Mr. brick comes into town
Unofficially unlocked BL's can use SEUS and PCC so I believe they can also use FOTA. All brick's came from officially unlocked phones. I haven't heard any case where it happen with unofficially unlocked BL.
If you show me one example they I will change my way of thinking

By my opinoin the easiest way is to unlock the boot loader and then you can do what ever you want..otherwise I would recommand wotan..
everything is possible, almost then, but indeed you cant root 62, but if you downgrade to 42 do this: tick only wiping data & cache with flashtool, restart your phone and then you are on 42 not so hard to do it if you on unlocked bl, but i think thats already explained sorry for that then, but it must work i try it many times on my own phone and lock and unlock my bl to several times, so good luck with it.

Hello everyone.
I had posted this in the Z forum, not realizing there was a Z Ultra forum. So I will just quote my previous post and add some info at the end:
Hello guys. New guy here with an Xperia Z Ultra phone.
I'm trying to load the Paranoid Android custom ROM.
Had a couple of questions:
1. I went thru Sony's instructions to unlock the bootloader. When I ran the fastboot -i 0x0fce oem unlock (e-mail code), the first error message I got was "FAILED - Remote - Command did not succeed". So I tried the exact command again, and then I got "FAILED - Remote: The device is already rooted".
I have searched high and low, and cannot seem to find any way to verify that the bootloader is now in fact unlocked.
2. Reading the instruction on how to install CWM/TWRP recovery menus, Every single list of instructions includes the following "This tutorial is only for Sony Xperia Z Ultra with 510 and 493 LTE firmware. Do not use it for any other carriers or variants"
Again, I have searched high and low to find a way to confirm what firmware version I have. All I know is I have the C6806 model, with the build number: 14.2.A.0.290
So can someone please help out a very confused guy here? I don't want to brick my phone by accident
So far it's still working ok

So far, after doing some major searching, I seem to have found that I currently have "290" Firmware, and that this Firmware is currently NOT able to be rooted. Is this correct?
Also, I still have not found a way to verify wether the boot loader actually did unlock or not. From what I have been able to read, it seems that if a proper boot loader was in fact, unlocked, it would have wiped all the data on my phone along with the SD card data.
So far, it seems everything on my phone is intact. So does this mean the boot loader unlock command failed for me? If so, why did I get the reply "this device is already rooted?"
I can't believe how difficult it is to root a damn Android phone! Jailbreaking an Apple device is 10 times easier!
First of all, it's usually pretty easy to root Android devices. In most cases it's only a simple click, but sony has done a good(?) job at fixing exploits, so it does it much harder for us.
Second, you can check if your bootloader is locked or unlocked by opening the dialer and insert *#*#7378423#*#*, go to "Service Info" and then "Configuration". If your bootloader is unlocked, it should say "Rooting status: Bootloader unlocked: Yes". It's easier to use Flashtool to unlock the bootloader if you're having issues using a terminal.
You'll find the rest here (including bootloader unlocking). If you need some help, ask in that thread.
If you aren't boot loader unlocked then "BACKUP TA PARTITION" from My Lord's guide @LordManhattan
Just incase you need to re-lock it for service

First of all it' pretty damn complicated and unrewarding to root a Sony device. Not all android but Sony definately. We checked, bootloader is unlockable. We unlocked and relocked bootloader prevoiusly because there is no robust, easy-to-install ROM for ZU. But time to time we try to root it.
Now, the question is the same: what should we do to re-unlock the bootloader if anything is OK, but flashtool says "Command did not succeed" for the first time and "Device is already rooted" for subsequent times at unlocking?
Please write some advice about the question, not about TA backup and your success. Thx!

Bootloader unlocking is a straight forward process. I've had a couple of strange errors in Flashtool while trying to unlock the bootloader, but just close Flashtool and try again. Also be sure to be on the latest version of Flashtool.

No sir, not at all. I wrote please, no demanding. Well yes, I'm a bit picky because there were no answer and I usually find some on XDA. Besides I used custom roms on Samsung devices for years (SGS2, SGN, SGN2) and I was disapponted when I bought my XZU that there are very few roms and I couldn't use them (I managed with very hard work to go back to stock in 9 hours after unsuccesful flashing).
So there is some basic problem every time. Like trying to root but cannot re-unlock because of some mysterious errors with no solutions.
Enough of my problems, your answer is much appreciated, will try to re-unlock some time. Thx!

Besides I used custom roms on Samsung devices for years (SGS2, SGN, SGN2) and I was disapponted when I bought my XZU that there are very few roms and I couldn't use them (I managed with very hard work to go back to stock in 9 hours after unsuccesful flashing).
So there is some basic problem every time. Like trying to root but cannot re-unlock because of some mysterious errors with no solutions.
Enough of my problems, your answer is much appreciated, will try to re-unlock some time. Thx!

Oh, i get that. I came from Samsung myself, and this is my first Sony device ever, so I've had some issues myself. I've gotten the same error message(s) as you before, and i think i restarted Flashtool and rebooted my Ultra and it was back to normal again - i think, but it "fixed itself" after trying a couple of times, so don't give up. It's also important to always be on the latest version of Flashtool.
It would also help us if you could tell us what you're trying to achieve, so you don't end up spending 9 hours on something that takes 5 minutes
@Champdor
From what I can make out you have never managed root your phone or back up the TA. If the latter is true then there is very little point in relocking the bootloader.
Yes the process is a little harder than Samsung, but the last device I rooted was a ZTE, and that was even harder to root and flash from what I can remember (yes this is my first Sony device as well, and I will buy another...)
Take you time and read the stickies that we have written and all should go well. Don't be afraid to ask (intelligent) questions if you get stuck, and read some more

I have not had this error so have not tested this, but what happens if you flash a full FTF and wipe everything then try to unlock the BL?
And remember that you can take a backup of the unlocked BL (re member to name it as such) and just flash that to unlock again. Doing it this way you don't get the format that happens when using the unlock code.
I followed this post to downgrade, root, i use Backup TA v9.10 to backup DRM Keys, use Flashtool 0.9.14.0 to unlock Bootloader, then to flash other Rom's (stock and customs), came back to Stock Rom .681, relock the Bootloader with Flastool 0.9.15.0 flashed the last .757 and unlock the Bootloader again with no kind of problems using Flashtool 0.9.15.0....

I dont know what else to suggest other than rebooting every thing and reinstalling all the drivers

You just back it up as you would for a locked BL. Just remember to make sure you name them well so you know which is the locked one and the unlocked one.
NEVER use a TA backup from another phone, you WILL HARD BRICK IT

Did you tried:
*#*#SERVICE#*#*
and confirm that the Bootloader is unlock?

The one who has the padlock or BLU?
