Relock Bootloader - Lenovo P2 Questions & Answers

Anybody there ever try or know how to relock bootloader?

It gives an error when you try doing it the normal way via fastboot oem lock.

Has anyone tried relocking by using third party apps (root) such as the Trickster Mod or tools like this one? It's a long shot, but an attempt nonetheless. I believe the Lenovo servers just register the request of unlocking, not the unlocking per se.

Yes 15 day wait is request for unlock, it's don't mean device is unlocked.
Only carry-in guys see is bootloader screen and boot unlocked logo.
When someone can relock, then can claim warranty as like of those who requested unlock but not unlocked yet..
Only thing is Normal fastboot locking dont work.

Is it possible to unlock bootloader if phone says it cant be?

I went to see if my bootloader can be unlocked from the sony website.
I followed the instructions by putting that code into my phone dailer.
Under the section if it says my bootloader can be unlocked, it says no.
Does this mean I CANT use custom roms?
Is there no other way to unlock the bootloader?
You can always unlock the bootloader, it's just a matter if it's free or not. It all goes back to whether you can use fastboot or not ( the tool used to flash kernels). If you bought your phone sim unlocked it more than likely means fastboot is enabled and you can unlock for free through sonys tool and be on your way to flashing custom kernels. If your phone is sim locked or you paid to get the sim unlocked by a code then fastboot will be disabled. So to rephrase: turn your phone off, hold the search button and plug it in to your computer, if the status light goes blue (and you're not on a CDMA one, r800x) then fastboot is enabled and you can unlock for free through sonys utility, otherwise you're going to have to use a pay service like this (~$24):

And to answer your question, yes and no, while it's not possible to flash ROMs that use a custom kernel like cyanogenmod without an unlocked bootloader you CAN flash stock based ROMs through the recovery made for locked bootloaders.
I have an R800A from Rogers.
The LED doesn't go on at all when I press the search button.
When I goto sony's website, I go into the phone settings, where it says if the bootloader can be unlocked, it says NO.
You mentioned a paid servers. Is unlocking the phone by allowing it on another network the same as unlocking the boot loader?
No, that's sim unlocking. Confusingly a bootloader unlock will actually sim unlock you as well though, the difference between the two is a sim unlock is a code and the bootloader unlock is done through test points. So ya, if you didn't get the blue light your only option for unlocking is a paid service, sorry.
Well actually an unlocked bootloader allows booting of custom(unsigned) kernel images and can be achieved with various means according to the situation.

Which is what I said in my above post... And the only ways to unlock it are:
- Through sony's online tool if fastboot is enabled and you have an IMEI (sorry CDMAs)
- Or a test point unlock, such as setool2 or omnius, which will enable fastboot
Oh ok sry then, thought u were being general.

Thanks for the help. I contacted the guy about getting it unlocked.

Locked bootloader PRO was unlocked???

Alright, here's the thing... My mk16i has a locked bootloader... Even still i ventured to attempt unlocking it through test point method and s1tool.
Apparently all steps worked, the s1 boot thing is now reported with an lowercase letter (just as mentioned in tutorial) which got me pretty hyped up...
but I just seem to be unable to get into fastboot mode, I do get the blue led for like 2 seconds and then is changes to orange and cell phone goes to battcharge mode (black screen with big batt charging icon).
The only thing I have not tested is first flashing the stock rom... I dunno if having custom rom has something to do.
Any ideas?

You've not unlocked it properly.
Well... I spent more hours into this last night, here's what happened:
Apparently test point method and s1tool can unlock the bootloader, I got notifications from s1tool, flashtool and Omnius that my phone was already bootloader unlocked... BUT it seems that the real limitation for "bootloader unlock allowed: no" phones is that fastboot is disabled, and searching through all the forums I only found one post of someone stating that no dev has been able to enable fastboot on these devices.
So, I even restored (relocked) the bootloader with s1tool in order to now try Omnius.
The good news is, Omnius works... I really have no idea how it did it, but Omnius did unlock my "unlock allowed: no" phone, and it uses the same test point method... the bad news is that it required me to buy an "Android single unlock license" for 15 euros... so I really hope it will be worth it.
That's all.
Good luck everyone.

[Q] Unlock bootloader if Allowed=No for Z1C

Hi there,
I have a network unlocked Z1C which came from o2. The bootloader unlock allowed status is No but the phone is rooted. Is there anything I can do to this to unlock it? I feel like trying CM on it
Thanks!
I have searched for answers to this but no joy...

If your bootloader unlock allowed status is no then you will most likely never be able to unlock that phones bootloader. I think your best bet is to contact O2 and tell them you want a phone on which the bootloader is unlockable, perhaps they can give you a special key to unlock the functionality, but I wouldn't hold my breath.
Oh and don't try CM on it, it'll just bootloop and you'll have to use SUS or PC Companion to restore a working OS.
...actually there is one hope, but it requires dismantling the phone. There is a test-point behind the battery which might enable you to put the device into a mode where it'll accept a command allowing bootloader unlock. But again, high risk, not sure if it's actually possible, easier to just sell the phone and buy an unlockable one if you want to run CM. Maybe you could even return the device, how long have you had it?
my z1c just turned up and ive got an bootloader unlock allowed :victory::victory::victory:
I have locked bootloader on EE in UK and have found that many of the tweaks I wanted can be achieved with Xposed modules. Give it a try but backup before you start.
Need a opinion by a dev
Hello there,
I was thinking about a test.
My problem is "Unlock bootloader allowed : no".
What could happen if i restore an other TA partition with "Unlock bootloader allowed : yes". I erase the old by a new one which unlockable. All i need is a TA partition build with a z1c which unlockable and the unlock code.
What do you think ?
Soory for my bad english
If you replace your ta partition it will most likely hardbrick your device.
What is a ta partition, i don't understand.
A bootloader is like a bios on motherboard.
But it is locked by a code.
The bootloader is the same on each z1c no ?

Flashing another phone's TA will hard brick yours, every TA is related to the phone which comes from

How you done this??? I tried hundred and half methods and still CAN'T unlock damn bootloader............

WARNING - Don't bootloader LOCK your phone.

a) There is no logical reason to bootloader lock a phone. You will gain nothing.
b) If you lock it there is a high probability you won't ever be able to bootloader unlock it again - no more mods - ever.
EDIT: Perhaps if you flash the "correct stock" meaning one like/identical to the one that you originally had on your phone when you unlocked it the first time, it will work...
Think about this, please, before you flash things!!!
Do you refer to lock and unlock the bootloader? I locked and unlocked it much times and I've never had problems (obviously considering the bootloader version).

Thanks for replying - could you perhaps write a guide as to exactly how you unlock your bl after using fastboot lock?
I have seen a few folks who appear stuck at that point and I and they would be happy campers if they could get around that!!!
Thanks!
EDIT: I added a comment about "correct stock" to the first post... This may be key to the folks that are having trouble...
You might look at thread
https://forum.xda-developers.com/moto-z-play/help/please-help-urgently-t3814260
But I guess I would have to call anyone who successfully locks and unlocks again their bootloader as darn lucky. Some, (many?) can't.
In the end I still have to ask "why the heck are you locking your phone" - what could you possibly gain? It's totally unnecessary. it can be a very expensive little line of code.
I lock my phone all the time, multiple times per day even! It's really easy to unlock: I simply put my finger on the sensor and voila!
Maybe you mean the bootloader? That would be a helpful little detail to add to the title of your post.

I've locked mine as I upgraded to a Pixel 2 XL and gave my Z Play to my father, so I don't really care if I can't unlock it again, but I'm sure that wouldn't be an issue anyway.

I prefer stock without modifications but sometimes when i have time to try news modifications or roms i used to unlocked the phone and after this relock again, the process that i use is very simple, i just unlock with the same code that Motorola gaves to unlock bootloader, i don't have sure but if you request unlock codes to many times can be a problem but i use the same code and works good.
Basically: relock as are specifcified in another topic in this device forum( using the last stock version that you used)
And after this unlock with code again
Obs.: Is not recommended to unlock/relock to many times.
Obs2.: I only did this three times and i don't know if has a limit

It is my opinion also that relocking is a bad idea. But if someone likes to do it, eg to get Google Pay working without Magisk, why do you want to warn him?
Relock only is possible in combination with flashing a complete correctly firmware. If something is wrong with the firmware you flash, relocking won't succeed. Your device won't be locked if it does not fully succeed or the firmware is not correctly signed. The unlock code is supposed to stay valid, you should be able to unlock your device as many times as you want using the same code.
a) is fine, but does not consider Android SafetyNet
b) is just wrong, and this already was written in a comment.
Please do not bump wrong warnings.

Question POCO F3 Warranty

If I use ADB to remove bloatware on the F3, will I lose my warranty? Is the Xiaomi ADB official (from Xiaomi)? Do I also lose my warranty if I unlock the bootloader and install a custom ROM? If not does Xiaomi say so on their website? What is the difference between using ADB and just deleting them manually? Thanks!
You will not use your warranty by using adb to remove bloatware. However you do waver your warranty by unlocking the bootloader to put a custom ROM on it. However you can theoretically still get a replacement despite this wavering of a warranty

Thanks! What do you mean theoretically? Can I just install MIUI again and lock the bootloader and sent it for warranty, without them finding out that I unlocked it?

You should be find. I have never had a Xiaomi and so didn't know how supportive they are. The official advice by Xiaomi is here:
What do you need to know about unlocking?
First and foremost you can only unlock your own device. This means the unlocking tool you downloaded must be logged in with the same Mi account on your device. One Mi account could only unlock one device within 30 days
Isn't locking bootloader against Mi's 'geek' spirit?
Locking bootloader is aimed to provide a better user experience, which we've been trying to do the whole time. In the meantime, we've provided an unlocking tool for senior users who know their ways around flashing and tweaking their devices.
The unlocking procedure will need Internet access to get the unlocking password. Also, the Mi Account logged in on the Mi phone and the unlocking tool needs to be the same. Otherwise, the unlocking request will be denied. This will ensure that ill-intentioned people will not get access to your personal data.

And that's where I come in.
I sent my Xiaomi Mi 9T Pro as a guarantee having had the precotion of flashing the global rom and re-locking the bootloader (I had a problem with my antenna, I received nothing).
They supported my Mi 9T Pro without any problem
