MI logo bootloop, no edl, locked bootloader, only fastboot - Xiaomi Redmi 4 Prime Questions & Answers

Hello,
I have a Redmi 4X stucked at Mi logo and restarts till battery reaches 0%. I've read I must unlock a bootloader first, but bootloader is locked by firmware (probably). ADB do not see the device, Fastboot DO SEE it. Commands in ADB console are "Failed" or are executed but a telephone vibrates and stucks at logo (Fastboot oem edl, reboot edl and so on). MiFlash see a device as a numeric string, unfurtunately I can't do nothing in MiFlash because of "critical partition flashing is not allowed" error.
Using chinese Mi PC Suite I managed to install v8.2.10.0.mammiea thanks to tutorial on YouTube, unfurtunately, after an update, the update bar on a Redmi 4X screen reaches 50%, after reboot it reaches more percent and like in a loop - restart, more %, restart and then stucks and never reaches full 100%.
I heard about MIUI Deep Flash Cable, I can do that, yesterday I shortened (jumper) two paths. I had "Qualcomm hs-usb qdloader 9008" as a device. I did a jumper myself (Data+ and GND) but computer see nothing

Softbrick REDMI 3S. Stuck at Mi Logo. Fastboot works. locked bootloader

Hai all , I am new here.
I need some help to unbrick my device. i tried almost all method and still no luck. the only method i havent tried is DFC, but i dont prefer to do it since its pretty complicated.
My device run rom Global Stable Miui 7 and i flashed Developer rom Global using EDL download mode.
there was an error and now my device stuck in Mi logo. I can still access Mi bunny fastboot ( vol down + power)
So far I have tried 3 methods
Method 1: reboot to fastboot mode, plug to pc, open ADB cmd prompt and type fastboot oem EDL. But no success because device is still locked bootloader.
Method 2: reboot to fastboot mode, plug in to pc, download fastboot EDL cmd from xda forum, unzip then run edll.cmd, device reboot to mi logo again.
Method 3: in Mi logo, plug in to pc, open cmd prompt, type Adb reboot edl, press enter but device cannot reboot to edl mode because it says I need to tap on confirmation dialog on device. But its not possible since device only load up to mi logo
Download the latest stable fastboot ROM from here http://en.miui.com/a-234.html then flash it.

If only it was that easy. I've tried 3 methods above but still no luck. Use Adb reboot edl, fastboot oem.
How to flash if its only stuck at mi logo
Because I had this exact same thing happened before. What I did was while it kept bootlooping at the Mi boot splash I held down Vol - + power until fastboot mode pops up. Then you'd be able to flash.

First off you cannot just unlock the bootloader easily, like in fastboot or anyhow, you need to follow the guides. And this is possible by the way only with a working Dev rom.
Well so now, you've to get miflash tool and flash either stock rom, or dev rom.
You simply hold power and volume down as long (can take some time) as it will show "fastboot" and some android art.
Then you follow the guides to flash either stock rom or dev rom using fastboot, and you're good to go.
I don't see why this wouldn't be working for you, try to stick exactly to what i said. If you don't know how to use Miflash then search at en.miui.com

Did you unlock developer mode as in my case I am also stuck in bootloop and fastboot oem edl is not working as developer mode is disabled thus oem is also disabled.
Hey!
I had the same Problem.
Flashing with Miflash was unsuccessfull and then EDL was locked. You can check this when the device is in fastboot and send "fastboot oem edl". Then there may be the message that EDL is locked. In that case you have to build a "deep flash cable". It is pretty easy. You can check this tutorial:
http://en.miui.com/thread-310325-1-1.html
But I would build it another way: Just cut a USB cable and reconnect all wirepairs with the open copper. Now you can just put "ground" and "data+" togehther and follow steps 7 to 9. At point 10 you can just disconnect the wires "ground" and "data+" again, so that all wires are connected normally again. Now you are in EDL and can flash with MiFlash.

URGENT ! Bricked, no download, no recovery after upgrade attempt.

Just bought this phone and attempted to upgrade from 7 to 8 and before so i done few things such as disabling some google sh*t. It upgraded and stuck on booting screen, vibrating sometimes. How do i handle this ? XiaoMiFlash says : flash tz error. Also there's no recovery and download mode.
If you have updated to MIUI 8.1.1.0 then I am afraid you have no other option left than flashing fastboot rom with deep flash cable using test point method presuming you have locked BL. For more info visit http://en.miui.com/thread-310325-1-1.html
But if you are still on MIUI 7 then you can flash using Mi flashtool in EDL mode.
For entering edl mode press volume + and volume - button simultaneously( test mode) and after plugging in USB cable with PC enter in windows CMD:
PHP:
fastboot oem edl
. After that proceed with flashing using flash tool
.
you cant disable Music, Youtube, Chrome,blah blah,... but dont disable Google, it will cause bootloop.
i figured this out after 15 bootloops lol
What ?! What the is deep flash cable ?! I don't have one ! Maybe i should exchange my Redmi 3s in shop next monday. It's stuck at mi logo and 3 circles, vibrating frequently...
UPDATE : Phone enters some screen where shows phone and cable and link to Mi Pc Suite. I click recovery flash option, but i says that phone is up to date. When i click recovery, nothing happens. How do i force flash ? Maybe i will flash a recovery rom using this mode, it's visible via adb.

I have given you the link about how to make deep flash cable by yourself. Xiaomi has locked EDL mode post MIUI 8.0.3.0. So you wont be able to flash normally in EDL or Emergency Download mode. Now you are in bootloop so either you can unlock your bootloader and flash in fastboot mode, in this case you have to wait bit longer or you can make a deep flash cable and flash in the mode you have mentioned i.e MI logo with PC suite sign.

One more device saved
rahulbarai, Dude, I love you, you saved my skin, thought my smartphone had the "bootloader" unlocked, because on the home screen it appears "unlocked" but it was locked, unlocked now I can resurect normally and use the device, thank you very much!

Axon 7 can't enter bootloader or recovery

I rooted my phone longer ago and the BL was unlocked, but I wanted to relock it because I wanted to sell the phone.
I just bootet into bootloader and typed in "fastboot oem lock" and then everything stopped working. I can't boot into the recovery or bootloader anymore. It only shows the ZTE logo for 1-2 secs and then it disappears.
I use the A2017G model and my PC is recognized the Phone as QUSB BULK, even when the screen turn off again.
EDIT: After I installed Miflash I get recognized as com10 and in the device manager I get recognized as QDLOADER 9008
Thanks in advice!

Can't Get into EDL even with ADB

I have an A2017U, Android 7.1.1, build B35, on MiFavor 4.2 and was looking to upgrade to 5.2/Oreo. I get stuck because I can't boot into EDL mode. I have not unlocked the phone but do have developer options & USB debugging enabled. If I boot with vol up + vol down + power, nothing happens even if I wait 120 seconds. I get a slowly flashing red dot. ADB works fine -- my device is recognized -- and "adb reboot EDL" reboots the phone, but not into EDL mode, just into standard mode. MiFlash doesn't see the phone.
I'm clearly doing something wrong but I'm at a loss what, given how simple the instructions are.

Try "adb reboot edl" from a booted phone.
EDL actually IS a black screen, usually without an LED though it might be red. Open Device manager and check under "unrecognized devices", or under "Ports (COM & LPT)". Should be there. If it is under Ports and it is callee Qualcomm HS-USB QDLoader 9008 then MiFlash should work
What are you planning to do? EDL back to B19 then unlock? Just curious

I plan to update to Oreo/MiFavor 5.2.
How do I issue the command from a phone? I know how to use ADB from a PC but not from a phone. That is what I have done -- enable developer options, connect the phone, verify that it is connected (adb devices) and then issue the command (adb reboot EDL).
Use the Edl tool by Djkuz
Install it to PC or laptop with all updated drivers
Open edl tool with run as admin
Boot your phone into ftm
Turn your phone off
Press and hold vol dn + power till you see ftm screen
Plug in your phone
Follow the on screen till it detects your phone
Select unlock then edl fix
Edl tool is here

Yes, but what are you going to do BEFORE updating to MF5.2?
you can't edl mifavor 5.2 because you will break stuff, besides you need an unlocked bootloader or you'll DFU brick your phone and you'll have to throw it in the trash.
I meant to issue adb reboot edl from your pc but with your phone on
On a side note, I recommend not using EDL Tool or axon7toolkit to unlock your phone. EDL Tool has a much better track record than other apps but it still has margin for error. The best way to unlock an A2017U is get a B19 EDL package and install it with MiFlash, then enter Fastboot and do "fastboot oem unlock".
Worked!

That worked, thanks!
Ive used all of the Axon 7 tools as well as adb commands and all work well in there own ways.
Script errors or command errors can be an issue as well as some software (ROMs, recovery and boot imgs) a few times I've had to edit a zip or img to make it work.
After a few boot loops on my HTC.
Is there an official MiFavor Update on 5.2?
My phone is still on 4.2 and can't find any updates.

only for Chinese (A2017) phones. It's 8.0 mifavor with the new mf5.0 interface (way more Chinese-looking). If you want to install it on a G or U you'll have to use one of the packages made for them (Usually for an update from other model to work you need to change its modem file to the one that your model uses, i.e. swap the chinese modem with the G's).

Oneplus 8 pro Bricked (please help and first read what I have to say)

I was having issues with the android 11 so thought to downgrade. Since the system wouldn't allow me to do it from the local storage, I thought I will just install TWRP and then flash the OS that way but in the process, I don't know what went wrong but fastboot will flash the recovery but when I tried to boot to it with the command it put me to Qualcomm crash dump mode. I downloaded the MSM Tool as I have gone through this process before but for the millionth time, I just can't put my phone to EDL mode. Every time I try with the volume up+volume down, keep pressing it until I plug the cable into it, the phone just goes to fastboot mode.
TL;DR - only have access to fastboot, no recovery, can't even install recovery because of crashdump issue. Phone not entering into EDL mode tried pushing it from fastboot to EDL using commands but doesn't work. Since it is at fastboot every time, device manager sees it as android bootloader platform. Device manager sees it as Qualcomm HS-USB Diagnostics 900E.
I've almost tried everything and I know device manager is supposed to see the device as 9008 for the MSM tool to work but it is NOT GOING INTO EDL MODE!!!!!
*sigh* any help will be really appreciated guys. Thank you.
