As the title suggest, I'm trying to unlock my bootloader but every time it fails because I have too many links. No idea what that means, but the more severe problem is that with other users the phone will be unlocked, but mine is still locked.. What should I do? Thanks in advance.
Hi guys I got the lollipop OTA for my nexus ( completely stock), never tinkered with it and the OTA installed but now its stuck on "google" screen and constantly bootloops. I have done some reading and I tried to unlock bootloader via Wugfresh toolkit and normal fastboot oem method but no avail, it gets stuck on the "yes" option.
Basically I have a locked bootloader which fails to unlock, and nexus stuck in google logo, any guidance will be much appreciated. Plz point me towards the right direction. :crying:
Try to unlock the bootloader from adb with OEM unlock command. The steps are posted above the factory images on Google's dev site.
yeah I tried that and tablet gets stuck on the yes option at unlock bootloader screen and nothing happens for 20 minutes , i have to restart it. I've read around and it seems like my emmc might have corrupted. Any pointers?

Well I can only think of one thing. Buy a new nexus. There aren't any listings for the Wi-Fi version and the LTE on Swappa. However there is some other devices on Swappa.
My bootloader is re-locked. Now i want to unlock it again but it always gives an error stating "Failed (phone is already rooted)". I have tried with flashtool and cmd-fastboot method but the result is always the same. In service menu bootloader unlock allowed says yes. Is there any alternate way to unlock bootloader once again? I can't seem to find this error on Google so am really confused what to do.
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?
So I'm out of answers currently and would like some help on this one
I installed Cyanogenmod from their website
Installed their rom, recovery
Locked the bootloader since that's what u should do
Today I tried to install a new update from cyanogenmod, it rebooted, and the recovery screen is only showing a black screen and every 5 seconds it will give a white flicker
I tried to unlock the bootloader again but it shows "FAILED (remote: oem unlock is not allowed)"
And I'm not able to get back into android, it will show "ID: xxxxxxxxxxxx" at the bottom and tries to go back into recovery
Help
why did you lock the bootloader when you aren't running the stock rom?
all the modding threads explicitly threads say to avoid doing this otherwise you'll have serious issues.
