Flashing Custom Rom - Xiaomi Mi 5 Questions & Answers

Hi all,
I have a redmi 2 and planning to buy the Mi5. I dont like using miui. I know that rooting doesnt void the warranty but does flashing custom roms affect warranty? Like if something happens to the phone while its on a custom rom and am not able to revert back to the stock rom before giving it to service centre?

You can unlock the bootloader and root your phone, no problem with it.
If install some custom rom, brick your phone and you can not revert to stock... you may have some issues while claiming warranty.

Rooting doesn't affect warranty, but as far as I know, your warranty is voided if you install other ROMs than custom MIUI builds. But today is nearly impossible to completely hard brick your device if you know what your doing. My advice is that you do a backup of your sensitive information (efs for instance) and flash only ROMs that you can trust works well. There's a lot of choices now that MI5 kernel is out in the wild

I was actually thinking about hardware issues. Like display not working. It happened to my redmi while it was in warranty. But luckily i was using miui rom at the time.

I faced problems about reboot on Mi5. while having power off to the set, a mi recovery ( 1. Reboot 2. Wipe data 3.Connect with Mi assistant) option has been notified on the black screen and takes a long time to back in the screen option). volume key (up) and power button also sometimes inactive. How can these issue be recover as earlier?

Milestone Bootloader and custom roms

Well guys as i said i'm willing to buy this phone but want full information.
I've heard that motorola milestone bootloaders is locked but i've seen some roms in milestone developement section. So how can we apply them? Will it break our device?
Of Course it can brick... ONLY if u dont know what u do. I have my Milestone 1month long and with a custom rom, it was quiet easy for me but because i read everthing 3times. bootloader is locked...very sad but u can use Custom ROMs.
I think it's almost impossible to brick the phone. I flashed all the roms avaible and when the phone gets stuck on the moto logo or bootanimation, I just need to wipe data or flash the rom again and it boots well, and if you really messed tbe phone, you can easily reflash the Sbf and apply the rom again.

Better use this method if you want 100% original factory ROM:

Thanks everyone!
One other question, if I do that, the phone will be unrooted? And if I flash the phone with a custom rom, this will make my LG like out of the box and I wont have any problem with the warranty?
Thanks
not with a "custom rom" but a "Official rom" !!
If you reflsah an official rom, you won't have any problems with warranty.
Hi,
I think I didn't explain myselft.
My question is this:
I want to flash a custom rom. I use Rom Manager, install a recovery image and install a custom rom. so far so good.
But if I have a problem with my phone and I have to use the warranty. This way I loose the warranty.
But if I flash the official ROM, when I send the phone to the warranty, they can tell if I flashed a phone with a differente rom, if I rooted it? If I flash it will erase the recovery image, the root,everything? And I will not have any problem?
Thanks
As i wrote before, use THIS method. After this you'll have ORIGINAL STOCK ROM which was in your phone after unboxing. There will be no sign of rooting, custom ROM, etc.
as I already said, if you flash Official rom of you region (or operator) (with method 1 or method 2, no matter) you'll have no problem with warrenty

[Q] What are the implications of flashing <official> ROMs outside your region?

Hello, first off, I'm new to the android OS, especially flashing ROMs. I did however have some prior experience in flashing other mobiles such as the Symbian platform on my previous Nokia phones.
I would like to try the new Firmware XXLA1 as of now Im using an OTA update kernel version of 2.6.35.7-N7000DXKL3[email protected]#2.
Btw, im from the Philippines and I bought this handset on this country.
So going back to my question, what are the repercussions and implications if I flash the LA1 official ROM from Samsung knowing that its a ROM for "Open Europe"?
if your phone is unlocked (No carrier restriction) you can flash any Stock ROM
Yes, i bought it unlocked. Will the app availability in the market change?
Also, since its an official ROM, would it break my warranty?
I Live in Indonesia, yes samsung Indonesia say it will break our warranty but you can flash it back to KL3 whenever you want to claim it..
Bump. I would also like to know of any important differences between stock roms if any. I live in the US and will be getting my Note in the next day or so and think I will root it but keep it stock and just uninstall any bloatware I deem unnecessary.
I recommend using it for a week before you try any (potentially) warranty breaking mods on it. Get used to it. learn how things work. Then when you start modding you will have a far better idea if the mod has broken something or not.
You can generally flash a ROM from any region, as long as you understand the language. You can flash RADIO seperately, and you would choose one that will work well with your local provider. Lastly, you can manually set the APN settings to lock onto your chosen provider.
Be aware that some new devices have a "binary counter" which will sometimes increase when you flash something. Your warranty may be affected. Spend time reading the forums learning about the issues before you flash.
Thanks! Sounds like a plan

Looking at the kernel version you have, it is safe to assume that we possess the same unit, and yes we have the same roots (oy, kapatid!) as well.
I started rooting my unit after a few weeks of getting familiar with it. Don't worry too much, since i was able to successfully flash root my unit and install CWM (clockworkmod), using the zergrush exploit.
Once CWM was installed, the 1st thing i did was a nandroid backup, just to keep a backup on my stock settings.
After that, i tried flashing custom ROMs, and it worked flawlessly, albeit with bugs. Just follow the steps outlined on each ROM thread and you should do fine.
Managed to encounter boot loops, phone not booting up, etc., but nothing too critical that made my unit useless.
As for your question, the obvious implication is that by flashing custom ROMs, you void your warranty. So, unless you have qualms in losing your warranty, then go ahead and flash a custom ROM.

[Q] Can i reset a S3 after custom rom so warranty will be valid?

Hi,
I have a Samsung S3 LTE(I9305) that are about 1 1/2 years old. I thinking of installing a custom rom to get a more mint Android taste. The Phone have been on repair 2 times and Im not sure if it will need another(bad reception) so its important to keep the warranty as long as possible.
I have heard something about a counter that will change if I install a rom and that I will not be able to reset this. The service will see if this counter is changed and if it is the warranty is broken?
BestRegards

If you have Stock Android 4.3, then you have the new Knox bootloader, which means that you will void the warranty if you mod it.
There is still no way to change this.
If you have the old 4.1 then you can do whatever you want, and still be able to roll back to stock firmware (anything but stock 4.3 or above).
I advice you to search the forums, for Knox related threads, this has been discussed many, many times.

Can I backup the rom in this phone?

Hi everyone, I want to buy this phone from Aliexpress at 220$, a super cheap price. The only problem is that they sell the phone with their custom rom which is not really the best, and the stock official chinese and english only rom gives the best performance. The problem is that flashing another ROM means that I will lose warranty, there's a way to backup the ROM and keep it stored on my PC so if I flash another ROM and need to send it back can flash again the Aliexpress rom so warranty is somehow restored?
Warranty questions are very theoretical because:
under which circumstances do you think you'll be able to flash original ROM to ship back? When you drop and break it? Because if you brick it accidentally, you can't flash it back either so that's not it.
have you ever looked at trackable shipping back to China? It's suuuuuper long, unreliable, and usually cost prohibitive especially for a device this cheap and fragile. Unless you have a super trusted vendor who's willing to work with you on a valid issue from #1, your device may not even make it back.
Regarding backup, yes, when you first install TWRP, you can do full backup of all partitions and offload them to external storage. This lets you restore original ROM as long as you only use TWRP for loading ROMS and don't flash new firmware via EDL / QPST. So if you want to play with GSI ROMs, you can recover, but once you flash the China ROM via EDL/QPST, there is no going back AFAIK.

Well, can't I just back-up the original recovery with an app like flashify, install TWRP, back-up the Aliexpress ROM and then install the original stock China ROM?
Then if I have to reinstall the Aliexpress ROM I can just flash TWRP, flash the Ali ROM, delete TWRP and flash the original recovery with adb or flashify.
I mean a lot of times I flashed the original stock ROM on my ZUK Z2, then proceded to flash TWRP and then I flashed a custom ROM again. And they share the same UI, because both are from lenovo
Stock recovery is not an issue because if you boot up the restored ROM for first time after a factory reset, it will replace TWRP with stock recovery on its own whether you like it or not.
On the other hand, flashing backlevel ROMs via TWRP is a problem. Generally speaking, EDL-flashed ROMS replace and update all kinds of data in all sorts of ways where default recovery has no access to (nvram, raw partitions, eFuses, etc). So while it may be possible to make it boot again after back-levelling through recovery, but it's definitely not recommended since there will often be conflicts/incompatibilities and will definitely leave traces of tampering. We would have to have a QPST image of the shipping ROM in order to do it properly (and only if eFuses are not blown to stop that).
And don't get me wrong, I'm not saying it's impossible. I am saying there are significant risks and we'd have to sacrifice a few devices to find out.

I understand, anyway I might have found a simple solution. I simply asked the seller if he can ship it with the stock ROM and he said yes, when placing the order I just say I want the stock ROM
Haha .. good thinking!
It will be interesting to see what they actually do and what it comes with. Please post back and let us know.
