MEG7 bootloop after OTA update (locked bootloader) Help - Xiaomi Redmi Note 5 / 5 Plus Questions & Answers

Hy everyone, I am in this situation since last Friday. Read and tried many guides and tutorials without luck. Here is my situation:
- I have the MEG7 version, I'm in south america. I don't know which version of MIUI I had before the brick (maybe a global fake one?), the phone was working excellent. Friday appears an OTA update of 225 mb, download and executed. After that the phone stucks in a bootloop, just the MI logo, powered by android appears a second and restart.
- Read guides and forums, then I did the test point according to knowhows.net/fix-xiaomi-redmi-5-plus-fake-rom-boot-loop on a 64 bit win10 laptop. The pc recognized the COM qualcomm port, I used the latest miflash 7.4.25.
flashed success stable cn rom but accidentally chose the "flash all and lock" option -> bootloop remains
flashed success dev cn rom -> bootloop remains
flashed success stable global rom -> bootloop remains
flashed success dev global rom -> bootloop remains :crying:
Tried other tools I read in miui forums, like XiaoMiTool, downloaded both china roms (global were not available, maybe due the mi site update?), the bootloop remains.
Keep reading, tried with the beta version of miflash, the proccess was endless, not luck.
Tried with and old miflash version 2016.08.30, the proccess end successfully but bootloop remains.
At this point didn't know what to do, tried to flash with miflash but with the device in fastboot mode, a "flash modem error" appears just 3 second after the start. Perhaps this error can give some clues of the real problem? :crying:
Now I'm starting to get frustrated. Could be the pc? I just have my laptop. If nothing works will borrow a win 7 32 bit pc. I used two usb cables to try luck, no luck. But, which is the correct rom to flash? the global or the china stable? I read can't flash dev roms with locked bootloader.
I tried almost everything, will preciate your kind help.

I guess that the successive flashings after relock bootloader were not really sucessfull.
When you using method point what you did after that? tried with miflash tool or miphone flash tool? so miflash tool don´t work in edl (download) mode, it is for fastboot mode.
Try enter to recovery with pwr + vol up and when appears logo mibunny release pwr button and do a format data and see what happens

---

MEG7 with locked bootloader needs global rom, not China one, stable or dev doesn't matter.

unlock your bootloader. altough your phone is bootloped. my situations is 100% same as yours. i spent lot of roms also. untill i try unlock (bootlooped phone) but succes. try it bro i hope succes. after succes you can flash into EDL mode and the phone booting normally.

I did test point with Miflash tool, all the guides I read uses that tool, is it possible with another?
the miphonemanager I have installed I think is from MiPc suite. Just installed, didn't use it.
I enter to recovery mode and wipe data too. Unfortunately it's the same.
Thanks for your suggestion.

How I unlock the bootloader can you help me? I tried in a simple naive way with adb command fastboot oem unlock, but some with the token I don't have appears. How did you do? I think all my problems are because the locked bootloader.
Thanks for your help.

Yes. I read one guide about that After to understand it, I flashed two global stable roms
- vince_global_images_V9.5.11.0.NEGMIFA_20180521.0000.00_7.1_global
- vince_global_images_V9.2.6.0.NEGMIEK_20180122.0000.00_7.1_global
I did the proccess succesfully, at least the miflash shows that.
But after the reboot, the device stops in "powered by android" and reboot again

First of all try to unlock bootloader, follow this tutorial and download Xiaomi Unlock tool from here: https://www.xiaomigeek.com/download-mi-flash-unlock-tool.html I´m not sure if this works if you didn´t linked before a miaccount onto your device and didn´t enable USB debugging and OEM unlock before.
MiFlash tool from here https://www.xiaomigeek.com/download-xiaomi-mi-flash-tool.html works in fastboot mode.
MiPhone flash tool from here http://chinagadgetsreviews.blogspot.com/2015/11/download-miphone-tools-for-flashing.html works in edl/download mode.
If you can´t unlock bootloader then you can try with MiPhone flash tool, to get in edl mode you have to first of all download and install the drivers for this method from here https://www.androidgyd.com/qualcomm-hs-usb-qdloader-9008-driver.html and open device manager from pc so your device has to be detected like qualcomm HS-USB qdloader 9008 and there are three methods as far I know to enter in download mode although one or more couldn´t eventually work:
- Pressing the three buttons at same time to connect to pc you have to get a short vibration then release inmediately.
- Second method trying to avoid to open backcover of device, search or made by your own a "cable edl" it´s not so difficult to do it (just youtube)
- Test point method is the last resort.
MiPhone flash tool works both unlocked or locked devices.

Wow, you gave me new ideas to try, really really thanks. Didn't know about miphone flash tool. I'll use tonight.
- When I did the test point the pc recognized the device in the COM ports, as a qualcomm hs-usb 9008, as I know, when this happens the phone is in EDL mode right?
- I have tried to unlock BL with the official tool too, but couldn't because of the device was not binded to my account. Anyway I have found this thread http://en.miui.com/thread-246705-1-1.html with some info I didn't know, about kedacom driver and disconecting internet, don't know if will work but I will give a try.
If I have luck I will let you know

After a few hours I tried the suggestions.
1.- Downloaded the MIFLASH UNLOCK tool from the mi web, tried to unlocl the BL, not success "account is not bound to device"
2.- Downloaded MIPHONE TOOL, I saw is similar to Miflash, but the last Miphone of the link is from 2014, nevertheless I tried with the device in EDL (with test point and the COM port), gave me this error:
"insufficient storage space to process this command :crying:
I observed that MiFlash works in EDL too, I mean, doing the test point recognize the device in the COM port too.
Also, I tried to flash a Global Rom with MiFlash but this time in fastboot, the device is recognized with many numbers. But I get this error:
At this point I really don't know what to do.
I guess I need to find a way to unlock the bootloader without bound account to the device.
Could this be useful? Before the brick, I added my Mi account in the device and I still can see it in Mi Cloud web:
Maybe I can contact xiaomi customer support and ask them to give me the permission to unlock the device.
I won't give up!

Here three things that you should try; other version of MiPhone tool, flash directly twrp, begin and wait the unlock process......
1- As far I know MiFlash tool doesn´t work in edl mode, just recognices device. Here you have a version from 2016 of MiPhone tool https://xiaomiflashtool.com/download/xiaomi-flash-tool-20160401 you have to set the path to your firmware folder next to "browser" box upper left there is an option to configure the files (prog_emmc_firehose_8953_ddr.mbn, patch0.xml, rawprogram0.xml) that are needed to flash the rom.
2 - Also, you can move all the rest of files and put only recovery (custom twrp) and after flash some custom rom from twrp, there are some threads explaining this process.
3 - To unlock bootloader you have to begin a process, put your sim onto other device and request to Xiaomi with this number and you should have to wait for the process, read carefully the thread specially the first steps https://forum.xda-developers.com/redmi-note-5/how-to/how-to-how-to-unlock-redmi-5-plus-t3750250

Time of flashing
Does anyone know how much is the average time to flash with miflash or miphone? In my notebook, win10 64 bit, dual core takes 700 - 900 seconds. I see in other images that finishes in 100 - 200 sec.

I have same problem like you in my MEG7
