Bootloader or oem unlock not working
- Thread starter yasaswi2509
- Start date
You will need to verify you Lenovo account, an e-mail will be sent to the address you used to set up your account. Once verified go back to OEM/Bootloader unlock to start the 14day wait.
Hope that helps.
I have verified the link that i got and it states success but iam not able to unlock its saying network unavailable even if i was connected to net
If you aren't on global release over the world version you can't unlock BL. Send a screenshot of about phone or build number.

Did you find any solution for this. I am also facing the same issue.
I thinks it started after the july security update for nogat!
No. The July security update came on August. The first post on this thread came in July. So, this has nothing to with the new security patch. I checked two days ago and it synced correctly. It was only yesterday that I started experiencing this issue. I just hope it's a temporary problem.
1. When did you start observing the issue ?
2. Do you have the 32 GB model out of 64GB model?
Same problem here and I have no clue what I could do so far now.
Is there no solution out there? Probaply not a good choice of smartphone?
I think we have proof now that is not an isolated issue. A lot of us are experiencing it at the same time. There was a similar issue last week for OTA updates, but after some pressure in the Lenovo forum, the servers were back online. I don't know if this is a temporary problem and the servers will be online soon, or OEM unlock service is down for good.
yesterday. it was the first time checking after the update.

After have tried Lenovos "support" before I will not send a bug report to them. Hopefully someone else will do it thou
I could run the oem unlock command in fastboot
No reset needed, just ignore the message ( LENOVO ID WITHOUT PERMISSION)

I am having the LenovoID without permission issue but this is happening when trying to turn on allow OEM bootloader unlocking in the developer options and I believe this has to be turned on before the fastboot command will work.
When I try the fastboot command of fastboot OEM get_unlock_data to get the code I need to convert for the unlock code, it returns Not Found for all values.
I contacted sorry about this but they want talk about it because they don't 'support it', I sent them the link for getting the code converted (https://motorola-global-en-uk.custhelp.com/app/standalone/bootloader/unlock-your-device-b) and said if you don't support it why do you offer the service? And they said yes we provide the service but don't support it.
. Asked who could give support on this and they said they don't know...---------- Post added at 08:22 PM ---------- Previous post was at 07:47 PM ----------
I've just seen in another thread that the OTA servers are down because there is a new update coming so maybe these are on the same server and it will be up again soon.

Sorry, but this is so funny. Because its sooo typical Lenovo service

6Hi everyone!
I figured it out.
It is again a certificate issue; however, this time the Lenovo server isn't to blame.
The Lenovo P2 has the certificate issue.. Namely, the phone doesn't have the issuer certificate for the Lenovo server in the Android certificate store.
To fix it, do the following:
Find a desktop browser of your liking (Firefox), and pull up the following website:
(https is important!)
Then, click the padlock sign next to the address bar, followed by the right arrow and "More information".
Click on 'View Certificate".
Then click on the certificate on the middle of the page, of the three available "Secure Site Pro CA G2" (issuer certificate).
Scroll down to "Miscellaneous", and click on "Download PEM (cert)".
Move this file to your Lenovo P2.
Then, on the Lenovo P2, import the issuer certificate by navigating to Settings->Security->Credential Storage->Install From Storage.
The phone will open up a file browser intent, where you can select the certificate. It will then ask you how you want to import the certificate. Choose "VPN / apps". You can give it any name you like afterwards.
After all that, try to do the bootloader unlock by going to Settings->Developer Options->OEM Unlocking.
Create or sign into your Lenovo account, and boom! It should work!
You may have to log out and back in to get it to work, though.
Mine worked immediately, but of course by immediately I mean that the 14 day timer started.
I was connected over WiFi, but also had the Settings->About Phone->Participate in Lenovo Experience Program option turned on, as others have suggested. Additionally, I added my phone to my Lenovo account via the Lenovo App (https://play.google.com/store/apps/details?id=com.lenovo.serviceit).
The system clock does not have to be changed, because the Lenovo Bootloader Unlock Server certificate is valid until 2022-06-30.
There are probably thousands of ways to get a hold of the issuer certificate; Firefox (or other desktop browser) seems easiest. I couldn't coax Chrome on Android to download the certificate for me directly to the phone.
Also, you might have to import the Root CA certificate (DigiCert Global Root CA) as well, in case your phone does not have it.
DANGER, WILL ROBINSON!
I am not sure who "Secure Site Pro CA G2" is, so please do not assume you can trust them absolutely as being forever in your certificate store. You have been warned. In any case, once you nuke the bootloader and install a new OS, it won't matter anyways.
Cheers,
mmx5Quick update. I just got a P2c72 device from a friend, I got the BootloaderUnlock.apk and was able to decompile it. For those who want to help. just get the .ODEX file in the system apps folder next to the BootloaderUnlock one. The details that I know until now are:
- The APK calls the unlock server for authorization using TLS authentication.
- The server replies with a bytes payload and the APK is in charge of writing the unlock flag.
I'll keep updating and if someone here is experienced enough in reversing, that help would be much appreciated5Guys, if you are interested, you might want to sign this Lenovo statement petition4I've been away of my computer for a while, after some hours of analysis of the BootloaderUnlock.apk code I figured out a way to unlock the Bootloader; but I need a chinese mobile number (+86) to receive a SMS verification code to continue with the process. Does anyone here has a chinese mobile number that can help?, if so, please contact me on private. Once I clear that step I will post how to unlock the bootloader, and provide the required files.3
I'm 100% sure that can be unlocked, as soon as I get a chinese number, to receive SMS.
