Warranty problem: Flashing to stock Nougat from a custom Pie rom

Hi folks,
I searched the forum and did not find a suitable thread that answered my question.
My Moto G5 has a charging problem and I want to give it back for a repair - it still has warranty.
I have read that flashing a custom rom does not necessarily invalidate the warranty, but to ensure that Motorola will repair the phone I would like to flash a stock (nougat) rom.
Is it possible without the risk of losing IMEI or other stuff?
Or do you recommend to send it back to Motorola with the custom rom installed?
Thank you VERY MUCH in advance!!!
Kind regards
Wolf

They will be able to see you have unlocked the bootloader regardless of whether you re-lock it
Just download the latest stock firmware and flash it via fastboot
If your base firmware is already oreo you can skip flashing gpt and bootloader to avoid risking hard brick
Don't downgrade your base firmware eg if it's oreo don't flash nougat (base firmware is stock firmware not custom rom)
I would flash it back to stock rom so at least they can't blame custom rom

Thanks!! I'm not sure, if it was delivered with Android 7 or 8. But I can flash 8 in any case, because its no downgrade?
And a last question: can I flash it also with TWRP? It's installed anyways...

Yes flash android 8 - note if it was never updated to android 8 you will also have to flash gpt and bootloader as well the rest of the firmware
You will need to flash the firmware via fastboot
Flashing via twrp is just like flashing a custom rom with no modifications & you will still have twrp installed and not stock recovery & still have a modified system partition etc

Thanks! Android 8 was definitely installed, only possibly not as stock firmware, but only as custom rom.
But I guess it's okay if I just flash all the files to make sure?

Motorola says, I have lost my warranty because I have opened the bootloader. They won't even fix it for money ****.

Depends what country you are in
In America or Europe you can argue and would most likely win in court that if your issue is totally unrelated to the unlocking of the bootloader they must repair it
Eg if the camera doesn't work because of a faulty component they must fix it
However if the camera stop working because you unlocked the bootloader & did some modifications causing it to no longer work then you're not covered
This would be the same for boot issues - If your phone no longer boots and you have unlocked the bootloader they can claim you have done a modification that now stops it booting
The general rule is if you unlock the bootloader than software/firmware booting issues are not covered but hardware faults unrelated to a bootloader unlock are
Again it varies depending on your country but the above is true for USA & the majority of Europe (EU)

Lock bootloader and update via OTA

Hello, I'm quite new. I downgraded from Pie to Oreo with Miflash a couple of years ago cause I had wifi problems. I got V9.6.11.0.ODLMIFF now. I want lock bootloader and keep updating via OTA. Which version should I install? stock version? Or some Pie version? I will lose all data of the phone right ? And where I can get the ROM? The old links I had not working now. Thanks

If you want security updates you have to use Android 10 but it's got some "known issues" you may not like. 11.0.16.0
https://bigota.d.miui.com/V11.0.16.0.QDLMIXM/daisy_global_images_V11.0.16.0.QDLMIXM_20201225.0000.00_10.0_79e5becb5f.tgz
If you just want to go back to Pie, you may as well get the last version. 10.0.20.0
There's a list of stock images here:
[FASTBOOT] [daisy] Xiaomi Mi A2 Lite FASTBOOT Images
Disclaimer I am not responsible for bricked devices or anything like that. YOU are choosing to make these modifications, and if you point your finger at me for messing up your device, I will laugh at you. Here are the current fastboot links for...
forum.xda-developers.com
That page also has install instructions if you aren't familiar.

Thanks @a1291762 Yes I prefer something stable so I'll install 10.0.20.0. I enter into fastboot mode and flash with miflash(clean all) right?
And I'm wondering if It is possible to lock the bootloader to update via OTA in the future? (clean and lock) It is possible with that version or you need to install the first Android 8.1.0 [V9.6.4.0.ODLMIFF] ?

I haven't used miflash only the fastboot scripts. But I believe miflash has a lock bootloader option. As long as you are also flashing all of the partitions, it's safe to use. Note that you do not need a locked bootloader to OTA.
You can use that version (10.0.20.0). There is no need to use an older one.
If you are downgrading you need to flash a newer modem because it fails if you downgrade the modem firmware. That makes it trickier to flash and lock. Replacing the file works with the fastboot scripts.
After install, you will need to immediately enable developer mode to disable automatic system updates. Otherwise your phone will install Android 10 automatically.

Thanks it has been helpful. So can I update via OTA after install a fastboot ROM, no matter if bootloader is lock or unlock? Is that possible when you downgrade?

Yes. OTA only requires the A/B partitions to be unmodified. You can have an unlocked bootloader.
If you root with Magisk or install TWRP then your partitions will be modified. If you don't do that, you can OTA without issue.

FWIW: I am lending my phone to somebody else, and didn't want them to have to put up with Android 10's quirks (particularly the need to reboot regularly) so I put the phone into fastboot mode and used flash_all_lock_crc.sh from the Android 9 (10.0.20.0) fastboot image. https://bigota.d.miui.com/V10.0.20....0.PDLMIXM_20200327.0000.00_9.0_2baf524aaf.tgz
Since I didn't have an Android 11 ROM handy, I left the 10.0.20.0 modem image in there, but it seems to be fine (for my single SIM in slot 2). I guess the modem thing (needing to flash a newer image) only applies to Android 8?
Before I let the phone on the network, I enabled developer mode and turned off automatic updates. Disabling the notification category Google Play Services -> System Update should prevent any prompts to install system updates.

Question Is it safe to flash any custom ROM and unlock bootloader on the recent MIU 13 release ?

Hi everyone,
I would like to know if it is safe to unlock bootloader and flash a custom ROM under MIU 13.0.3 SKHEUXM ?
I've seen people having bugs, hence why I'm asking if anyone has given this a try ?
Furthermore, I was going to do this update in order for the firmware to be updated then switch to a custom ROM, but I could go for custom ROM first then flash the newest firmware (even if I'm more confident on the first option which should work out of the box, and preserve warranty in case something goes wrong during flashing firmware, always gotta keep fingers crossed).
Thanks for any help on this matter.

If you updated to the latest ROM, your firmware is updated along with it, there's no need to flash the firmware again seperately. Flash the ROM of your choosing, Magisk if you absolutely need it, and enjoy. Most ROMs these days also pass SafetyNet if you do not root your phone.

It's not very safe, you need to be careful.
Make sure your PC wouldn't crash or that your USB connection may be unstable.
Take your time in setting everything up and reading up some resources on the internet.
If the Flash-process aborts for whatever reason, do not reboot phone. Your phone may not be able to reboot back into Fastboot and turn black.
As for good resources of information, I recommend the YouTube Channel "Munchy". He covers Xiaomi Flashing very well. You can trust him.
https://www.youtube.com/channel/UCDSfvwvAsKE4Nrosu7bTbJw
You might also want to use a Custom ROM with passing SafetyNet, or to use Magisk Root. If SafetyNet fails, you can't use some apps.
I personally use Xiaomi.eu Weekly Android 12 with Magisk Root + SafetyNet Fix Module. No bugs, I'm happy
My only wish was that I had Over-The-Air updates. With most Custom ROMs, you unfortunately still have to download & flash the ZIP-file manually in TWRP Recovery.

Can't verify update

I'm trying to update my Redmi Note 8 Pro global from 12.0.8 to 12.5.1 manually since it doesn't find new updates no matter what i do.
I downloaded the ROM and selected it in "Choose update package", it tries to verify the update for a few seconds then just show me the message "Can't verify update. Couldn't verify update package." or "Can't verify update. Can't flash this stable ROM."
I tried to install it via USB flashing it with mi flash tool, still got the same message.
Does anyone know a fix for this, or at least why this is happening? Any help are appreciated.

Unlock bootloader, download the appropriate ROM for your version of smartphone (fastboot version), delete the check from the flash bat and you can flash. First try flashing, see if it boots. If everything is OK, you can try flash and lock.

is there any way to do this without unlocking bootloader?

If you are scared of losing the warranty, you wont once you relock the bootloader. Any other way, you ve tried it and it didn't work

It's not about the warranty, it's about my bank apps that might not work with the bootloader unlocked.
I'm going to do some research on how to unlock and lock the bootloader, as I didn't know it was possible to lock it again. Thank you for your help!

I fear that you might have misunderstood me. You cannot relock the bootloader while running a modified stock rom/custom rom. You can only relock the bootloader on a stock rom.

Are you running the latest stock version of your rom? Then, if you plan on using a smartphone with a locked bootloader, you already are. With a locked bootloader you won't get unofficial updates.

The rom from Xiaomi.eu is a custom rom. Xiaomi.eu is a group of enthusiasts who modify the stock Xiaomi rom, adding and removing features. Make no mistake, that's a custom rom. Close the bootloader with that one installed and you hard brick your device. The method I told you is the official one, which makes downgrading and upgrading your phones super easy. Now, if you want to flash a different version of the stock rom to your phone and lock the bootloader afterwards, be careful. There were reports that nothing happened and everything worked, but unfortunately not that many. A different stock rom might have a different cell tower reception, not adjusted to your country. So you might get less reception.

Hey today my phone unlocks so i will be doing the update. I just wanted to ask that on website:- https://xiaomifirmwareupdater.com/archive/miui/apollo/ there is miui updates (i downloaded a fastboot 5.2g latest one 12.5.10.0) and firmware of 150mbs. So i have to install both firmware and miui rom? Or just stock miui rom? I read somewhere that firmware is for user which come from very old stock rom to latest one. So how to install firmware?

Question A bunch more questions from a noob

As title really, never flashed a custom ROM (at least not since my Galaxy S2) and while wait the 7 days to unlock the bootloader i'm trying to gather as much info as possible. So here goes;
1) Whilst I wait for the bootloader to unlock can I still turn off my phone and swap sim cards or will it reset the timer?
2) My Poco F3 is on MIUI Global 13.0.7.0 (SKHEUXM) - do I need to downgrade to 13.0.3.0 as per the instructions here?
3) The instructions for installing Crdroid lists an optional step for installing "DFE" but I cant seem to find out what DFE actually is.
4) Is it important to know if my phone has an A/B partition system and if it is how do I check for it?
5) After installing Magisk what other modules/tools/apps do I need to ensure Google Pay/Wallet will work as it seems a recent update has made it harder to fix.
6) Are there any bits of advice you can give for a avoiding a bootloop and/or bricked phone situation? Are there any common mistakes people make leading to a bootloop or bricked phone?
I think that's everything for now
Thanks

1) Yes.
2) No, 13.0.3.0 is the required minimum, you can always use higher.
3) It disables forced encryption.
4) Poco F3 is A/B.
5) If any issues arise, you can always hide magisk and use safetynet fix.
6) When people don't follow installation instructions properly.

It works, with DFE you can flash files from internal storage in twrp. But it also compromises phone security, so it's recommended not to use it.

If my phone is A/B do i have to do anything different when i flash Crdroid in TWRP?

Almost all modern phones now ship with A/B partitions. So no, just follow the instructions given by the rom developer.

1. I unfortunately can't answer.
2. I wouldn't, 13.0.3 to 13.0.7 is very minor
3. DFE = Disable-Force-Encrypt = Android by default is encrypted.
DFE.zip removes the Boot-argument responsible for encrypting the Userdata-partition on the first boot, located in /vendor/etc/fstab
4. Poco F3 has an A/B-Partitionlayout. Most phones released with ~Android 10+ have A/B.
5. Personally, with the recent change, I tried many things to get GPay to work, got fed up with the Cat & Mouse Game with Google, and locked my BL.
6. If you flash using Fastboot Mode and the Flash aborts during a Partition-flash, don't reboot your phone, because otherwise your phone may never reboot back into Fastboot etc, and only show a Black screen.

No difference.
Further Notes about DFE:
If you don't use DFE before First Boot, userdata-partition gets encrypted, which means, beyond that, only TWRP SKKK will be able to access the userdata-partition.
If you decide to flash DFE once, you must flash it directly after every Update in TWRP, otherwise your phone may bootloop. At least that was the case for me! Before an update I decided I want my storage encrypted, but I got a bootloop. ^^
I wouldn't use DFE. Just leave it encrypted.

If you lock your bootloader after flashing a custom ROM does the custom ROM still work as intended or do you have to go back to stock?

Your phone will bootloop if you do that, because locked bootloader prevents custom roms from starting, thus it can only be used on stock roms.

No, I don't use a Custom ROM anymore. I'm back to Stock ROM, MIUI 13.0.7 for Europe.
Don't lock the BL with a Custom ROM. Only the Official ROM. Otherwise you risk hardbricking your phone.
