Dear ladies and gentlemen,
I've occasionally erases serial number (and IMEI) of my Nokia 1 device using SPFlashTool Format + download. After that I was able to reinstall the system using one of ROMs from this site and root the device by means of mtk-su. However I cannot unlock the bootloader because it requires a serial number that was erased.
Is it possible to unlock the bootloader without the serial number (m.b. using root)?
Sincerely yours,
GH1.

Good day !
I have come across a situation of unknown bootloader of SK17 .
I found some shop in Hong Kong is selling some cheap SK17 (not sure if it is the same as SK17i) . I asked the shop keeper and they said that the bootloader is locked , but without SIM lock .
So , will someone confirm me if this situation is possible ? As I read some post in this form it indicate that locked bootloader is usually because it is branded , i.e. SIM locked . If it is SIM free version does it mean I can make the bootloader unlock ?
And , what if the system shows "Bootloader unlockable ? No" ? Is there any way to work around this issue to make the bootloader unlock ?
Thanks so much !

Hi!
A simlock is something totally different to the bootloader´s lock.
No Simlock means that you can use any sim of any provider you like and who´s band is supported by phone´s hardware.
The bootloader ist locked by sony basically to prevent people from removing the sony Firmware even if it is not branded. A second issue is probably to prevent people from unlocking and playing with the firmware who do not know what they do.
Before the lock of the bootloader it was easy for everyone with one-click-tools or similar to root the phone. This could have led to many RMA procedures at Sony
But there must be a possibility to unlock it due to the terms of open source software.
So there is no need for you to unlock the bootloader as it takes any simcard anyway.
What the issue about sk17i sk17 and sk17a is, I do not know yet. But I´m curious about it
hi... how to know that your xperia mini pro unlock already in bootloader?
my rooting status is,
Bootloader unlock allowed: YES
is it already unlock in bootloader?? or not
It meens that it is be allowed to unlock your bootloader. It means not that your bootloader *is* unlocked.
Hi Poedel ,
Yes I understand SIM locked and Bootloader locked is different . But I wish to install 3rd party roms (CM7 rulez) , so I still wish to know how to unlock the bootloader .
So maybe I change a little bit about my question .
1) a sim unlocked device with locked bootloader (bootloader unlock allowed : no) cannot unlock due to the SIM lock . Then will it allow to unlock if the device change to SIM unlocked ?
2) Any method to work around the locked bootloader (bootloader unlock allowed : no)
3) Any way to unlock the bootloader if IMEI code cannot be used to extract the unlock code ? As I know some of the shop will use flash rom writer to wipe with another device firmware and IMEI will changes (it happens last time when I buy a X01HT) .
Thanks a lot !

this is still confusing The simlock does not take care at all if there is a bootloader-lock or not. I never ask someone if I am allowed, definetly not mr. simlock
2) Any method to work around the locked bootloader (bootloader unlock allowed : no)

okay, usually you'll go to the sony's dev site bootloaderunlockl.sonyericsson.com (don't know the correct sub, could be correct) and authenticated by your IMEI and email you'll get the unlock code. Without IMEI you won't be able to unlock. But even if you IMEI changed you can try the current IMEI. What I think is that Sony just saves the Email and IMEI into a mySQL Database to cope with the situation if your device enters RMA à la "you unlocked, your fault". It would be rather not the way that they look if your current IMEI really belongs to the device there. I would simply try it. BUT!
There is a post where a method is shown to root your ph0ne without unlocking the bootloader.
So here are both links:
rooting without unlocking not tested by me (even not yet read *covering*)
default way like I did it
Dear Poedel ,
Thanks , that's exactly what I wish to know .
So in worst case if bootloader is not going to unlock in normal way , I should use the test point function to bypass it and flash another room and firmware into it , and unlock the bootloader again ?
Thanks very much !

Dear fellows,
I got a Alcatel One Touch Evolve 5020T (T-mobile) from US as a gift.
When I put my India's SIM card into it, it says network locked.
On searching XDA (and other) forums, I learnt that the SIM slot is locked. In MTK Engineering mode, the option of SIM ME lock (unlock) is grayed out.
I tried to use SP Flash tools using the scatter file but I get an error - Secure Baseband. Need auth file. I dont know where to get this auth file from.
I tried using Alcatel One Touch Upgrade S 2.8.0 software as well. I used the model number - 5020. But the moment I connect my switched-off phone, it says - "Read terminal information failed, Unplug device, remove battery and try again..." [Screenshot attached]
Questions:
1. Is there anyway to reset the firmware...so that the SIM ME Lock menu can re-appear?
2. I have the NCK code with me (from a trustable source), is there anyway to directly push it to the phone and unlock it?
3. Are there any special tools available to directly unlock this phone?
I am not an expert at this, but have working knowledge of linux/android.
Any possible answers?

Not sure why you never got any responses. I know this is about 18 months late but hopefully it will help someone else with similar question on Alcatel OT 5020T.
1. Is there anyway to reset the firmware...so that the SIM ME Lock menu can re-appear? You can get to the SIM ME lock menu by dialing *#*#3646633#*#*
2. I have the NCK code with me (from a trustable source), is there anyway to directly push it to the phone and unlock it? No. You can´t "push" unlock codes into a phone. It has to be processed (the phone has to "ask" for an unlock code first).
3. Are there any special tools available to directly unlock this phone? Yes. GB-Key, SigmaKey and other dongles can DIRECTLY unlock the 5020 and a wide variety of Alcatel models without any unlock codes. But those tools are quite expensive and only make sense if you are providing a commercial unlock service.
Hello,
I want to bring my dad's TF201 back to life. It's on stock but that's extremely slow & laggy so I want to flash a custom rom on it. The only problem is that the device is locked and de unlocking tool from ASUS does not work on my tablet.
It says that there is a unknown error and something with the connection. That could be a fault with the serial number but when I go to device info, the serial number is visible so that is not te problem I guess.
Is there a fix for it or is there another method to unlock the TF201?
EDIT: I succeeded to unlock my bootloader. After a lot of tryouts I got a popup to log in with my google account.
But that was my other problem, It was constantly saying that my password was invalid (2 step verification was disabled).
So I removed my google account from my tablet and after another try my tablet was unlocked.
Hello all, after 2 days of trying I ended up with few problems with Chinese version.
1.Serial number and factory serial Null so bootloader unlock code won't unlock it.
2. updated to the newerer version so I can't downgrade.
3. Maybe because bootloader is locked I can't enter the menu (1.fastboot 2.ForceErase) even using button trick
4.still can enter fastboot using adb commands
Since I can see update.zip in my watch SD storage after stock update, can I create update.zip where it can be tricked to update to US version?
Or a way to make the unlock code with null serial number so I can get output from unlocking algorithm from that serial and try to unlock bootloader.
Thank you.

Keep trying, locked bootloader does not mean that you do not have an access to ForceErase. Maybe this video will help you (https://www.youtube.com/watch?v=ZlXoeq30vM0). In my case I reached menu after counting to 6.
Hey there, I have a question, that has been bugging my head for 2 days now. So i tried unlocking the bootloader of my Lenovo K10 Note, but it just didn't work properly. So i started with enabling the option for oem unlock and usb debugging. Then i installed Android SDK and followed the common steps. Keep in mind that oem unlock is enabled. So I then proceed with fastboot flash unlock and pasting the img that Lenovo sent me. The command goes through, then it types sending unlock and then... it freezes. I then go to restart the bootloader from the phone and the flash unlock fails, pointing out a variety of errors(out of links, ect.). So my question is, what do i do know? Thanks in advance!
