Relocking bootloader and warranty.

I got my H9L 2 months back and had rooted it (and unlockedd bootloader). Im having a big battery issue battery drains too fast. I want to get it to service centre as waranty is not over.
I've read posts saying if I relock bootloader I'll get waranty back but some says I won't get back warranty even if I relock bootloader.
Can someone sort this out please

IF you've unlocked the bootloader and rooted the device you have no warranty in the eyes of the manufacturer, it states this in the terms and conditions when you get your bootloader code from them.
See when you unlock the bootloader you get a warning screen upon booting the device and relocking the bootloader will not get rid of that warning.
However have you tried to see if the battery issue is intact an software issue. I.e have you wiped caches, checked if an app such as Google assistant WhatsApp Facebook is running in the background. Do you have the same issue when booting android into safe mode????

That's strange. I've relocked it today after flashing compete stock using HuRupdater tool.
I'm not having the warning screen I had earlier when my bootloader was unlocked.
So does that mean I'll be able to claim my waranty now?
And I've tried different ROMs the issue persists.
If they ask if I've unlocked the bootloader(since I've given my product number they might know) I'll just tell that I took the unlock code just in case, as they were shutting it down and that I haven't used it. Well at least that's the plan
So will they know that I've unlocked it earlier if there is no warning screen? As I've told I have complete stock firmware including kernal and recovery like @Fredin_ told.
Please reply fast.

If your no longer showing that Warning message after going back to stock then you can try and claim warranty if you wish, however they might have other ways to finding out if the bootloader has been unlocked.
So put your claim in and see what they do, they will either honor the Warranty or not Honor the Warranty and give you a quote for the work.
Personally if i unlock my bootloader and root it i'd just put up with the issue as i fully knew that the warranty went when i unlocked the device.
But i will leave it upto you how you go about it.

Help!!!!! Moto g6 variant xt1925

View attachment 4629305Good evening, since I upgraded my phone to OPSS27-82-87-3 version I have not been able to block the bootloader again, when loading an image it says boot loader error security patch I need someone who has this firmware since I could not block the bootloader of the phone if I do not have this variant, and this link does not work up to 222 Mb and it falls
https://rsdsecure-cloud.motorola.co...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
so download wherever it always generates the same download error
link of the image https://ibb.co/i2tV5q
I need the September patch security firmware opss27.82-87-3 a link that works, without this I can not go back to relock bootloader

Why are you trying to relock your bootloader? And you are not likely able to relock the bootloader. Sometimes flashing the exact firmware already on the device re locks the bootloader but not every time. There is no reason to relock your bootloader. It will not make the device as it was never unlocked for warranty purposes. It will not stop Motorola from being able to see that it was unlocked.

You can do it but there is no point. If your thinking relocking the bootloader will get passed a Moto service center and or sending it in will pass there warranty check your mistaken. if you do a logcat and look through it you will eventually find in the logcat it says your warranty is void. Also requesting the unlock code and using it voids your warranty. each phone has a unique unlock code only made for that phone for it's bootloader. For example me and a friend have the same Moto g6 play but his bootloader unlock code is not the same as mine. Long explain short Your warranty is voided the second you unlock your bootloader it doesnt matter if you relock it. And you can't hide it from moto. And as to what @madbat99 said. There's never been an instance where re-flashing stock firmware at least in my experience has relocked a bootloader for Motorola devices. Not saying your wrong I just personally have not heard that or seen it happen yet. it still doesn't matter though because the warranty is still voided from doing it the first time. I've heard of that happening with some Samsung devices but the warranty was still voided. I'm not sure why people think relocking the bootloader is necessary it doesn't affect the phones performance when It's locked or unlocked

is not to pass it as a guarantee I just want to leave it as it was, also had already been able to block the boot, only for the last update of September I can not block the bootloader for being firmware of July, and the link that there is, the firmware of September does not work download certain part and the connection drops,
Also, with the patch version of July security if I could block the boot loader

K20 Pro Global - stuck after installation wrong rom

After wrong rom update, phone is in bootloop.
Bootloader is locked.
Pc recognize phone only in edl mode (with TestPoint)
If I install a stock global rom (like when it was new) with Miflash can I restore it?
Wich rom I need to download? Fastboot? Someone can link me a good stock rom? (Global version)
Wich version of MiFlash I need to use?
I try with 2/3 different rom but MiFlash give me error: cannot receive hello packet

With bootloader locked you can't flash trough fastboot. I think the only way to recover is bring to assistance.
How is it possible wrong update? It was an OTA?

If it was an OTA of the stock ROM he could recover the phone by flashing the stock ROM in recovery mode with MI Flash.
If you flash any ROM other than the stock version that came with the phone (like flashing Global on a phone that came with China ROM) and then relock the bootloader which is the default option in MI Flash then your phone is hard bricked which is something Xiaomi owners have been doing for as long as I've owned Xiaomi phones.
The only way to recover the phone is via an EDL Test point Flash which requires both technical knowledge (the phone needs to be opened and an electrical short created by touching two specific points on the motherboard) and also an authorization code that Xiaomi will never give out.
Bricking the phone this way voids the warranty. Some service centers are willing to try an EDL Test Point reset but the cost is 100% out of pocket for the owner and is paid whether the process works or not.
Most people eventually recognize that they've turned their phone into a paper weight and getting it working again is not going to happen.

The situation kinda frustrates me; not because it's happened to me (I hope it never does) but because Xiaomi likely designed the ROM mismatch brick on purpose. If they didn't they know about it now and really should have done more to rectify it.
They've also set the default MiFlash settings to lock on every flash.
I'm guessing they did it to protect their revenue; deter people from importing devices cheaper then flashing the ROM for their region. But I still don't get it in some ways - even with a China handset flashed with a global ROM you're not going to get the network bands you'd get on the regional variant. I'd say that's enough to justify the price difference.
A brick is going too far imo; someone still purchased that hardware with their hard-earned money. Also a major concern for e-waste.
In general I've lost faith in Xiaomi's warranty altogether. I bought a global variant of their handset as I assumed it meant global warranty (Xiaomi earlier misled UK buyers on this by accident via hukd). I was wrong of course; as it's a grey import it's not covered - however I've always considered Xiaomi synonymous with imports. Their phones aren't as widely available here (but that's changing) and their warranty service is restricted to an incredibly small proportion of owners through authorized resellers. It was too expensive to purchase the device domestically. Some argue that you pay for warranty when you buy domestically though I suspect they already factored it into the production cost of each unit anyway.

Phone was bricked after flashing Mi 9T pro rom with fastboot (But phone is K20 PRO)
Phone is "open", I made the Test Point and the phone is seen by xiaomiflash in EDL mode.
How can I do now? I Think I need a K20 PRO Global Rom, someone can post me correct rom for flashing it with xiaomiflash in edl mode?

Question Unlocked bootloader warranty question

I currently have OP7P, I'm planning to buy either S22 ultra or upcoming OP10P, I got to know in samsung once bootloader is unlocked it break Knox and that is irreversible, and they say it will be hard to get warranty even if later I lock bootloader and unroot stock rom.
In my OP7P after I flash stock rom with msm there is no visible sign if bootloader was ever unlocked, is it same with oneplus 9 and 10? And is it correct that service center will be able to find that it was earlier unlocked and they can refuse warranty?

OnePlus doesn't usually care if your bootloader is unlocked for service....

Question Does a bootloader unlock on Note 10Pro blow any EFuses?

Hello.
I want to ask if someone here knows, if unlocking the bootloader changes any EFuse states in the SOC, because Samsung does that
to prevent Google pay from working again on the device, even if the bootloader gets relocked. Now the question is, if Xiaomi does that too?
Does any one here also probably know if, and when yes, what EFuses are set on the Xiaomi devices from factory?
Regards

No.
When you relock bootloader it's like from the factory and your warranty isn't voided.

Do you know if they have "Etched" the checksum of their Bootloader into the SOC by setting the configuration EFuses, or is
it possible to replace the entire bootloader through another one (Normally this isnt possible because the SOC itself is locked
to the Cellphone manufactuerers signed bootlaoder by blowing config fuses. Does Xiaomi that too?
