551ml Bricked after updating to new offical MM build. (help pls)

Hello guys, I noticed this morning that MM was officially released today. I followed the steps on to update my phone. I downloaded the rom for 551ml put it on my root of my internal storage, after that a pop up showed that there was a system update. I did the update and now my phone wont turn on now. It vibes twice and nothing comes on the screen. I have no idea how to fix it. I was on the latest firmware that system update would give me (184). If someone isn't busy could they possibly help me out. thx..

Same issue here, have you found a solution yet?

I think mm system.img boot.img splashcreen.img need mm bootloder to run and at the moment twrp doesnt work with it, if you install mm via twrp you only updating these img and bootloader still lp that causes your phone cant boot. (Correct me if im wrong)
So now you need xfstk downloader to recover your fastboot and then flash .194 raw firmware using asus flash tool then adb sideload mm firmware from stock .194 recovery, theres guide how to do that in here but im forget where
Sorry my english are bad too..

I used XFSTK to upload firmware etc... but after upload firmware, the phone will vibrate twice and download of OS will not start... the soft will try 20 attemps to connect with the phone and the OS part can't be download on the phone... I'm stick at this point.

Hello guys, i'm trying to unbrick my phone, i'm following this guide http://forum.xda-developers.com/zenf...l-usb-t3405840 but when i get to the end of te install of intelSoC my device is detected as Moorefield for like 4-5 seconds and then it disappears. I've been trying to solve this for like 4 hours now, a little help would be much appreciated.

If you don't need to use twrp everyday (maybe just a backup from time to time) you'd better keep stock recovery and whenever you need something from twrp, you just boot into it without flashing with the usual "fastboot boot twrp.img" command. That way if you ever upgrade again you don't have to remember whether you removed twrp before. But that's just an opinion, since if done that way, you'd need to have yor phione hooked to a computer to get into twrp, an that's not always possible.

thanks

Flash stock rom.
Start your phone and follow the setup (language=>wifi=>google account=>.......).
Now in your phone go to setting and find factory reset.
Reset your phone and reboot.
The problem should be fixed.
Don't use TWRP for factory reset, it wont work.

Really
That simple
When you say stock rom
What would be the best to install the marshmallow or nougat rom and which version ,the one on this forum ?
Thanks

Yes, it's simple and it worked for some of us. You can try to flash this rom BLU_V0090EE_V11 from here: https://forum.xda-developers.com/vivo-5r/how-to/blu-vivo-5r-stock-roms-bluv0090eev11-t3492756
Then do factory reset and see if everything is OK. If not, flash the other rom V25. If yes, now you can update your phone via update option in setting or use Sp flash tool. After update, if you want to flash twrp and you going to stay on marshmallow it's better to use old twrp from here:https://forum.xda-developers.com/vivo-5r/how-to/twrp-recovery-blu-vivo-5r-t3492739
If you will update to nougat, use twrp for nougats from here:https://forum.xda-developers.com/vivo-5r/how-to/twrp-recovery-nougat-7-0-t3701235

But then I accepted an ota for nouagat update and imeis disappeared again
Any way to restore the imei on nougat as it only works on marshmallow

to use MauiMETA_v9.1635.23 to repair Imei, search tutorials on youtube,

So.. I flashed to Nougat with the stock rom and lost the imei (but 4g and sms still work, dont know why).
Tried installing Marshallow again, doin Factory Format, with Chameleophon, mtk engineer mode and nothing, i still cant get imei.

@rasik107
If it worked before custom ROM, best to restore stock firmware and test your touchscreen.

Booted TWRP 3.2.3 off twrp site via fastboot boot twrp.img, phone got stuck, after poweroff-poweron touch sensor calibration was off.
Flashed original firmware, relocked - no go.
It's also hosed in TWRP, so not a firmware bug.
Can someone with a working Mi A1 dump all their partitions from twrp (adb pull /dev/block/bootdevice/by-name) and share privately as i hope touch sensor calibration data was stored somewhere and was damaged by the twrp?

I got the dump from someone with working TS and it didn't help on my device.
From dmesg in twrp I've noticed that my TS firmware was 0x0a version while working device shows 0x10, flashing stock tissot_images_7.12.19_20171219.0000.00_7.1_d39fa89 aaf.tgz helped in the end and TS fw got upgraded to 0x0a as shown in my dmesg after first boot.
Now I'm going to restore my emmc dump (to restore my imei and MACs) and will try to reflash this again.

Solved by installing an old version of stock miui through mi flash tool. Old as in android 7, not 8, be careful to check version when downloading from miui site.

Mi A1 Wifi Issue after flashing stock ROM

Greetings!
I have been using Resurrection Remix for about a month now, but when the stock April patch came, I decided to return to stock firmware. I downloaded the most recent flash package from the official Xiaomi site and flashed it via MiFlash. When the phone booted up, I could see every wireless network, but when I chose to connect to any of them, the signal dropped a bit and it said "Connecting..." then immediately "Saved". After a few automatic try, it would just say "Disabled". The router settings are just fine, the phone could connect to it before I flashed stock rom. I also tried to download a bit older patch (9.5.4), which was neither good. After it I tried Nougat, but it still won't connect to the network. The hardware must be fine, since it was working an hour ago with Resurrection Remix. Could anyone help me out? Thank you in advance!
EDIT: Solved. The problem was with the persist partition, which is not flashed during the firmware flash process, so you have to flash it separately in TWRP. You'll have to download THIS FILE (persist.img), move it to /sdcard of your device, then boot to TWRP (you don't have to flash TWRP, only boot in it), tap on "Advanced" -> "Terminal", then type in the following: "dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27". After it, reboot the phone into fastboot mode, and flash the firmware again. That's all.

Wifi works, but sim = 0

I managed to fix the WiFi and SIM (no imei).
Just flash persist.img if you only have the WiFi-issue.
There's a somewhat complicated guide here in the forums as well. Just google "mi a1 imei fix xda".
I'll help you tomorrow if you cant fix it.

Here is solution: : How to restore IMEI permanently after using factory flash
I have the same problem with IMEI, the fix is permanent.
After the repair can be uploaded any rom, including Oreo .

I also twisted up my IMEI. When I tried to downgrade to 7.8.23 it was boot looping. I was trying to solve it for 6 straight hours. Eventually, somehow the phone became unable to boot into fastboot (or anything else) for no reason. (a random shutdown occured during fastboot mode while no command was given). I had to turn to the Xiaomi service, since nothing could be done with the phone. Guess I'll have to use my old nokia flip mobile for 2-3 weeks.

Mods please edit the op with a warning not to flash someone else's persist partition, this can permanently damage your chances of recovering your OEM Mac address and other sensors data, there's already a better solution out the called "persist resurrector" on XDA. !!!!DO NOT USE THIS!!!

Thank you so much, Bro. You saved my day. I am getting the similar problem. And ended up flashing multiple ROMs. but nothing worked out until I found your post.

while using this tool make sure you enable USB debugging or it won't work.

EDIT: Solved. The problem was with the persist partition, which is not flashed during the firmware flash process, so you have to flash it separately in TWRP. You'll have to download THIS FILE (persist.img), move it to /sdcard of your device, then boot to TWRP (you don't have to flash TWRP, only boot in it), tap on "Advanced" -> "Terminal", then type in the following: "dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27". After it, reboot the phone into fastboot mode, and flash the firmware again. That's all.

try flashing the latest void kernel.

SOLVED:Stuck at PIN input, then reboots

Well, I f*cked up.
Fastboot works, I can flash stock rom via Xiaomi Flash. Flashing completes without any problems. A notification about encypting phone shows up, at 3% it jumps to 100% and resumes boot. Now after each boot, phone freezes at "input your sim pin" and reboots. Over and over again. What can I try, please help :

I've also tried wiping cache in default recovery, no luck

Try to format data in twrp or stock recovery.
If it does not work flash an android 8.0 or Nougat ROM. Do not lock the bootloader.

Let me guess. From Pie to Oreo or Nougat?

will give it a read, it it works, I'll PM you and you'll give me your paypal address. Fair is fair.
can't unlock OEM, because I can't boot up to developer tools. great, just great. will try to fix that first.

if you can boot to fastboot try to flash stock pie 10.0.4.0 with miflash, after that your device should be able to boot, than unlock OEM and bootloader and downgrade to what version you want

I can get to fastboot yeah, but MiFlash tool says that remote oem unlock is not allowed. So I'll probably have to open it up for EDL. Reboot to edl isn't working. Thanks for the advice tho.

i had a problem like yours, but i have flashed stock rom in non EDL mode and everything had start to work apart LTE band missing that i restored with qualcomm's tools
which stock rom have you try to flash? are you downgrading from oreo? bootloop on android one logo after downgrading is a common issue due to ARB (anti rollback protection)

reward is cancelled from this point on i will reward the one who helped me so far tho. still working on solving the problem so winner has not been decided yet.

you don't understand.
There are no winners and no loosers.
You are free to donate to anyone you want, but your post boost and encourages a bad attitude.
If people start to solve only paid problems, the spirit of the community will be destroyed.

The problem is with the Pie specific partition table
I write the whole guide from memory, so it can differ a bit.... I skipped some steps ( erasing, reboot, fastboot mode, TWRP loading via fastboot, OEM unlock )
From previous writings I think you can know the skipped steps.
Keep in mind: It is dangerous, you can loose your IMEI ( it will only work again with Pie - or there are some writings at forum how can you manually change it. ).
Steps:
1 - Backup with TWRP (fastboot) efs,persist,modem & make copy to your computer and or to your cloud provider.
2 - Create a new folder in Internal Storage -> TWRP -> BACKUP -> With a new date directory ( the backup already made one, make a new folder, with different date )
3 - Download someone's older TWRP backup from xda (I cheated, I copied the following links ) :
(I'm still a new user, so can't directly write url's )
Mediafire : https COLON SLASH SLASH bit.ly SLASH 2QU5NtC
Mirror: Google Drive : https COLON SLASH SLASH bit.ly SLASH 2UN1DTo
4 - Unpack, and copy EFS to the folder created 2 point
5 - Fastboot TWRP -> Restore EFS
6 - Flash the Official latest firmware from en.miui.com ( If you want to make sure go with EDL mode )
7 - Now, the IMEI & Mac addresses are missing. Don't panic! Download update with System Updates.
8 - When you are on Pie again, restore your first TWRP (fastboot) persist partition
9 - One more System restore
At this time, you will have IMEI & Mac addressees, and hopefully a working phone.
Hope this helps. The same thing happened with me 2 weeks ago. This is how I solves it.

Thank you, I solved it yesterday. Hopefully this post will come in handy for other people!
