Cant flash Pixel Experience - Redmi 9 / Poco M2 Questions & Answers

I tried removing my IMEI 1 because of an issue I had, but in doing so I ****ed up my phone in terms of AOSP roms.
I can flash some, but the IMEI I do have does not work with the roms that do flash on it. But the worst part is I cant even flash the android 10 Pixel experience which is my favourite one.
EDIT:Im dumb. You need to be on MIUI 12.0 for the roms to work

Random reboots

Hello,
there are many people suffering from random reboots on mi5. is there a guide to get rid of those?
i bought a new mi5 which already restarted during the first setup. those reboots continued to happen randomly while using the phone. sometimes it isnt occuring for half a day and then it happens 3 times in a row.
there is something hat makes me think it is not a hardware issue. when the phone is in the bootloader or when i install a new rom through fastboot, the phone has never rebooted.
i have tried so many different roms (Resurrection, lineage os, different versions of miui) and they all have that reboot issue. some of them seemed to work better than others, especially with custom kernels like the dragon kernel it happened way less, but still several times a day.
is there something i can flash that is going to stop this rebooting?
when i got the phone the bootloader was already unlocked. i could find any information about that... i thought it might be due to the fact that it had an english miui installed. but is it always like that or are all mi5 shipped with a locked bootloader?
greetings!
Hi
I think maybe something wrong with hardware..also IMO.. if you're bought the new mi5, it should has a locked bootloader, no matter what miui rom version installed..bootloader should be at locked state if that's a real new mi5.
okay thanks thats good to know!
i havent really understod what the different firmwares are for. do they change the baseband version? is there anything else they do? can you recommend me stable firmwares or will they not change anything?

Ofcourse..different version of the rom it can be has different firmware/ bootloader too..it depending what the android version and the rom it self.
From my experiences trying some custom and official rom, the best until now for stable daily used what i needed is xiaomi.eu rom that's until now currently using it..it's miui rom that's still based from official miui china rom that are already optimized for global used. You can try used official global miui rom with more language already added but different from xiaomi.eu is official global to much google apps that i don't really needed it for my daily used, that's why i'm still using xiaomi.eu rom.
Had the same problem
Hello, I had the exact same problem as you on MIUI global 8.1.4.0 with locked bootloader. It didn't happen that often, but I think it has to do something with the RAM, if its completely full, the phone will reboot. I fixed this by installing the xiaomi.eu ROM, you always have like 1+GB free RAM with that ROM. As your phone is already unlocked, it is very easy to install a different ROM. I hope this helped you

I officially surrender. My minotePro is NUTS. Help?

It all started a while back, while I had Miui 7.5. After one year working perfectly, it suddenly started bootlooping.
Well, I tried everything. Factory reset, full wipes, mi flash, flashing xiaomi.eu, flashing en.miui, stable roms, developer roms, buying a new battery and replacing it, installing by OTG with full wipes.. absolutely EVERYTHING.
And after having done so many things, my phone DID come back to life with only one rom: leo_images_5.9.17_20150826.0000.7_5.0_cn_b8ece3aeb3
Now, why on Earth would it work perfectly with that one, (I don't like it and I would love to change it), and it doesn't work with the newest stable or developer one, global, xiaomi.eu, 6.12.22. LineageOS....
With all of those, when I flash them just like I flash the one that works (with twrp 2.8.6), it either shows the MI logo forever or it restarts every 10 seconds.
Does anyone have any idea?? Thanks!!!!
Do you still have that ROM? I need it to try solving a NO SERVICE issue
Yes you can't install other rom just try to download the newest from their page

How anti-rollback works?

I read this article, but I still don't understand completly how is anti-rollback gonna affect my phone.
Is it only MIUI thing or even with custom ROMs I won't be able to flash earlier version? Let's say I already have newest version of MIUI based on Android 9 so anti-rollback is present. Can I install, let's say LineageOS 15 which is Android 8.1? And can I switch between let's say LOS 15 and LOS 16 as much as I want? And... what if one day Android 9.1 is released and custom ROM is made, if I install it, does it mean I can't flash even the most recent version of MIUI until it would be based on 9.1 either? Cause it would detect that I had newer version and wouldn't let me flash it, right?
So the question is, I guess, does only MIUI check anti-rollback index before flashing or MIUI just activates this "feature" in my phone and then it's embeded somewhere deep and I'll never be able to go back again even with custom ROM? My thinking is... if MIUI version XY brings support for ARB it means, that earlier version, let's say XY - 1 doesn't have that support and therefore it can't check and know that it's earlier version, right? So that check has to be burnt into phone for good and it is gonna permanently affect my phone even without MIUI, possibly restrict flashing even for custom ROMs.
But I'm no expert, so I would like to know from someone who understands it.
Thanks!

Typically, there is no need to worry when flashing custom roms even when based on a stock MIUI rom. Also, this is an on-device problem, not something server side. Lastly, once custom recovery is in place, even if the phone were to fail to boot because of anti-rollback, I wouldn't see it being an issue since a custom recovery is in place and it should be easily recoverable.

Treble ROMs

Hi guys, I have an SM-N960F dual sim exynos Note 9 and i have recently discovered this whole other element of ROM flashing known as project treble ROMs. I tried to flash a few different ones and i could only get one to work and the rest all just either bootlooped or stayed on the initial splashscreen. I was wondering if anybody could shed some light on them a bit for me and perhaps knew exactly the best way to flash them, and what firmware is best to start on beforehand etc? I found the whole thing EXTREMELY confusing especially with venfor images and kernel images etc...
Thank you for any input/help!
We can't really use the term Project Treble when talking about Samsung phones. Technically it is implemented, but Samsung being Samsung, it's quite a non-standard implementation and not really compatible with anything else.

Ive flashed a few of them onto my phone but it seems to be a bit of hit and miss as to whether they boot up or not. The ones that do have been good in terms of the size and speed etc, I even flashed a generic copy of OneUI which worked well.
I am on Pie base using the Dr.Ketan rom, so I tried a few GSIs which are supposed to be compatible with Pie base. I took them from here.
The way I flash them is:
1. Factory reset from TWRP
2. Flash the GSI as system image
3. Flash stock kernel otherwise you will be stuck on boot logo or you will get into bootloop. To flash the stock kernel I just use Dr.Ketan's rom, because the UI upon flashing allows you to choose and flash stock kernel and skip everything else.
(They mention that we should flash Permissiver also, but it gives error so I can't flash it)
So those GSIs boot up, but they are barely usable. The "System is finishing update" and "System setup will start soon" are stuck for me and never finish. Also for example in the PixelExperience9 from this collection I was not even able to add my Google account because of the system auto-closing almost all system apps that I try to open.
It might be that these things should be done in a different way, but this is my experience for now. So..... back to Dr.Ketan ROM. I was really hoping to get the MIUI GSI as daily, but it seems impossible to me.
EDIT: Lol I realised we are the same people talking on the other thread also, so you gave me the link to the treble collection.

restart, reboot, force close, find device closed, bugs, android 10 and 11

my phone has random reboot and force closes in any rom, It does not matter I flash custom or stock ones (recovery or fastboot), I tried any roms any solutions, but the problem exists in android 10 and 11 based roms.
the only good one is android 9 stock or custom.
it is the last time I bought xiaomi phones.
it is full of bugs.
I also disappointed about android.
I wish, u guys do not have any problems like me
