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.

Bootloader does NOT get locked when you flash back to stock. You have to re-lock it manually whhen on stock. I cannot guide you through this as i have never done it

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.

do you unlocked bootloader?
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!

Oh, are we demanding help now?
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!

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....

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

UNLOCKING THE BOOTLOADER:
This may wipe your phone, so backup your stuff
• Go to Sony's dev site
• Request the unlock key and check your mail straight away. Email is quick these days.
• Open Flashtool on your computer (yes, the one you installed earlier)
• Click the "BLU" icon
• Follow the steps and enter your unlock key

Sorry , that was all I knew to suggest. The only phone I recall being unable to be unlocked is one from Bell Canada.
I used the Xperia C method and my Rooting Status say: Bootloader Unlock allowed: Yes; after this process I try to install TWRP with this tutorial: http://forum.xda-developers.com/xpe.../bootloader-unlocked-custom-recovery-t3285521
And I have some troubles. I check my Rooting Status again and this turn to No from Yes. Now my bootloader Secured say Yes, when it say No. And now i can't unlock my bootloader (again).
1.- This screenshot it is when I made my bootloader unlock process. http://prntscr.com/9hiiu
2.- This screen it's when I tried to flash TWRP; the status secure say Yes, after the unlock... http://prntscr.com/9m7ji1
IDK What I have to do.
Can't see your images. Also the thread clearly stated it was only C4 TWRP. The C5 Ultra version is available for Beta testing. If you can flash the recovery your Bootloader is Unlocked simple.
Yes I know. The problem is before the tutorial, thank you very much for responding. Look, what happens is that I had already unlocked the bootloader; Unlock Bootloader I said: Yes. Now I tried to do the procedure you posted, I realized that now Bootloader Unlock my cell saying: No, so I failed in the attempt to flash the recovery. My question was, why after saying Bootloader Unlock: Yes, Unlock Bootloader went on to say: No, and thus the secured: yes.I do not understand what could have happened, why it changed the configuration ?, this was in a period of one week before you will post the tutorial.
Will said bootloader survive an ota update on c4 & c5?
