Flashed Wrong OS; 4x Won't Power On - Xiaomi Redmi 4X Questions & Answers

1. I have successfully requested and unlocked my 4x.
2. I wanted to install: https://forum.xda-developers.com/xiaomi-redmi-4x/development/rom-2017-08-07lineage-14-1-t3653016
3. First step, install TWRP following this: https://twrp.me/xiaomi/xiaomiredmi4x.html (Fastboot Install Method (No Root Required)
3a. Using version: twrp-3.2.1-0-santoni.img as downloaded from the twrp site
3b. After many reboots and tries, finally get into TWRP. Password not accepted at first, press cancel, get to TWRP menu.
3c. Wipe->Advanced Wipe->System,Cache,Dalvik's/Art cache. Swipe, then get errors. Try again, errors. Press reboot option.
4. 4x OS will not boot. It is stuck in endless cycle of Mi logo, and recovery/TWRP boot (vol+ and power) does not work. Only way to break Mi logo is fastboot (vol- and power).
5. Try to reset phone so I can start entire process (starting at 2) all over again following this: http://en.miui.com/a-234.html
5a. Used this version: http://update.miui.com/updates/v1/fullromdownload.php?d=mido_global&b=X&r=global&n=
5b: Edited the flash_all.bat following this: https://www.youtube.com/watch?v=_osMF9EubhI
5c. Left fastboot mode, device will not power on at all.
And as I type this I realize I put on the "Note 4x" instead of the "4x" version. I should have used this version: http://update.miui.com/updates/v1/fullromdownload.php?d=santoni_global&b=F&r=global&n=
As a potential next step I've identified: http://en.miui.com/thread-693884-1-1.html
I need some expert guidance at this point. Thank you.

Recovery is both volume keys plus power.
Maybe you should reflash firmware as well(v32).

you can try it
download and install last version ADB https://dl.google.com/android/repository/platform-tools-latest-windows.zip
enter to TWRP both volume + power. after choose Advanced - ADB Side load .. run it
run command line on PC after: adb sideload /path/to/rom.zip
wait while rom will be installed... press Reboot to System (if TWRP don't reboot byself)
wait near 5-10 min for first time rom startmust work.

I have gotten to recovery with just vol+. Regardless, the phone will not turn on from either combination.

vol+ and power ... have menu for reboot to Fastboot and Recovery .. choose it for reboot to TWRP and flash phone or in Fastboot and flash with Miflash

The phone will not turn on. Not to any menu. Not for any key combination.

you know,, if you install twrp,, the combination key vol up+power cannot work,,, he work if you hold vol up+vol down+power until MI logo then realease.

This sounds a hard brick to me.
Every replies about Fastboot and Recovery are pointless, because he cannot start the phone in Fastboot.

either it's hard bricked or motherboard stopped working after the wrong flash.
i think you should give it try on test point method once as you have mentioned in this thread (do it on your risk) or you may have to visit service center since any button combination isn't working for you.
what is the status of device when connected to PC or on charge ? is it charging ? does led light blinks ?

I used the guide I posted in OP to fit it, though it wasn't easy. Gonna try lineageOS one more time. Thanks to all who tried to help.

I had this same. I saved my phone using this toturial:
and
http://en.miui.com/thread-693884-1-1.html
Be careful with the screen and sim tray!
My phone was 100% dead (no fastboot or recovery). I have tried everything before and only that works.

How To Restore Everything Using Fastboot?

Hi.
I got into problem after flashing the Beta 7.0. I need to restore my phone using fastboot since the eRecovery that I got gave me only 3 options: download latest version and recovery, reboot, shutdown.
I have tried flashing the system.img, boot.img and recovery (both stock and TWRP). During flashing everything looked OK without any error but I still get this when booted:
"Your device has been unlocked and cant be trusted - your device is booting now..." and it got into bootloop.

try to put the update.app of B130 on dload folder on SD Card, external sd or OTG and it should be able to flash..
i had a similar issues, almost was going to go the service center when i was able to flash the firmware B130 thru the auto update from OTG (flash drive) (Hold Volume Up + Volume Down + Power).
The dload / 3 button method doesn't work any more, here is what worked for me:
I got to the state where I could only enter Fastboot mode (Press vol- and connect power cable). When I tried to start the phone / go into recovery it would only display the "Your device has been unlocked and can't be trusted" Message. My mistake was to relock the bootloader in an attempt to get the recovery to work.
I looked for hours for the answer, here is what worked for me:
follow this tutorial (the "update firmware" part)
German
English
But with real precision, every step.
If you have a european unbranded L09 you should be fine using the firmware you can find on this site:
https://thedroidguru.com/download-install-huawei-p9-b394-nougat-update-europe/
if not you gotta find the full firmware (3 files!!) yourself - good luck!
If you only want to go back to stock you should be fine afterwards.
If you want to install twrp for root/custom rom/... follow these steps after installing twrp with the tool:
Upon flashing TWRP, FIRST THING YOU MUST DO is rebooting to TWRP. If you don't do that, stock Recovery will ovewrite TWRP.
Find instructions in the TWRP threads how to enforce immediate booting to TWRP, upon you flashed it:
-Type on the PC: fastboot reboot -but don't press Enter yet.
-Press and keep pressing Vol+ and Power buttons together on the phone
-Press Enter on the PC and then immediately unplug USB cabel.
-When phone shows Booting, release Power but keep pressing Vol+. button
Hope this helps, I don't take responsability for anything, happy flashing!

DLOAD does not work for half a year, ie since Huawei stopped releasing FullOTA-MF-PV builds (it worked only for them)
Here, on XDA there are two proven guides for recovering Nougat (not just for EU c432 but for all custs, not only for P9 L09 but also for L19, L29) - just search for them: HWOTA7, HuRUpdater
PS: You have crossposted the same to several threads?!

My phone won't start

Hello,
i think I've broken my phone, I hope you can help me.
I followed this tutorial that you can download here : (I can't post the link because I'm a new user)
I've tried to unlock the boot loader with success, then the installer tried to install a recovery (as the text in the command window said) and the progress stopped, I have waited a couple of minutes but nothing happend and I disconected the phone from my computer (I know that was a bad idea).
Know my phone won't start, not even in the recovery mode. I can hold the Vol +, Vol - button and the power button but only the huawei logo appears, then turns the screen black and nothing more happens. I have also disconnected the battery for some minutes but this didn't change anything.
The only positiv thing is, that Fastboot still recognizes the phone when it's connected to my PC, but I still can't enter the fastboot mode.
I hope you can help me and save my phone,
thankfull Robin

First of all thank you for your reply. But I can't put my phone with my computer and minimal ADB in fastboot mode. The device is found with the command "adb devices" but it has only recovery status. When I type in "adb reboot bootloader" then Huawei logo flashes up and then it goes back to blackscreen.
I fixed it
I fixed the phone by myself. I'm not an expert at all and this is for the people with the same problem.
I think the problem was, that the phone won't leave the recovery mode, because it was listed with "apd devices" as "recovery" for the whole time.
So I tried to install a stock ROM via SD Card with a tool named au_temp.cfg and the phone actually did more then just turning back off when i pressed the Vol+, Vol- and Power key. So the phone actually entered the bootloader but I got the wrong stock image, but this didn't mattered because after one try the phone got back to normal mode and booted quite fine. So I think the main problem was, that my phone was stuck in a recovery mode and needed help to exit it.

Hi,
I can understand your frustration. You can use two methods:
01- Switch off phone. Press Volume Up and Down buttons together and Press and hold Power Button for 3-5 seconds. Phone will boot and take you to TWRP.
02- Instead of using buttons, use "adb reboot recovery" it will take you to TWRP.
Regards,
Aero

Now i adb commands stopped working idk why
My phone also has the same problem ،
I waited for the battery to finish. Then, with a chance to connect the charger cable and playing with the buttons, I was able to enter the main rom
plz help me . How can I fix the boot loader?
Is it possible to install the original ROM on the bootloader again?

Having some trouble rooting now sure where is the problem

So I followed this guide, watch?v=eBAzsEw-QVsAnd, He used an auto flashing program, got to the step where you flash the recovery, it worked, the ADB was recognized and the writing of the recovery was successful.
But, when I tried booting into TWRP (by power + vol-up) I just get a black screen for a few secs and then the mi logo again.
Also, I manually installed TWRP 3.3.1 and still the same thing
Any suggestions?

When you restore the phone try using the latest TWRP from here https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
Copy the TWRP image to the adb/fastboot folder and rename to TWRP.img.
No need to use any tools, just boot into fastboot connect to the PC then in command prompt navigate to the adb folder and use
Code:
fastboot flash recovery TWRP.img
After installing boot immediately into TWRP and flash what you need.
In fastboot still press and hold power and vol+ until it vibrates. Then let go of power and keep pressing vol+ until TWRP boots

Lg g6 bootloop i cant do anything

Hi guys !
We had unlocked the bootloader and after that, had installed twrp but it didn't start in a few attempts. The "Your software cannot be checked for corruption" screen appeared. I had read somewhere that it's just a warning about the risk of installing custom OS and I just should go factory reset, so I did (and that was a stupid idea, I know). And then the bootloop started to happen. My PC can't see my phone and I can't turn it off in any way
To turn it off just hold the power button... while its bootlooping, it will shutdown. Connect the phone to the pc and enter the bootloader. type fastboot devices, if the pc sees it with a question mark but cannot apply the driver, download the bootloader interface driver and set it manually, now retype fastboot devices and your pc will see it in fastboot, after that, reflash twrp or your recovery of choice, wipe all, format data and install your rom of choice.

I am having a similar issue after flashing the TWRP image - phone when into boot loop - resetting did not help. Now, it continues to reboot at the LG logo.
I was able to get it into the fastboot menu (once in like 50 times) - but am unsure of how to repeat the steps (to get it into fast boot)
Can you list the steps, and at what time do you press the vol- button, and when to connect USB cable?
Many thanks in advance

Hey! Don't lose your hope yet. I managed to fix my phone!
So first of all just to be clear - my problem was that after trying to flash ROM using Custom Recovery (in my case it was OrangeFox Recovery) my phone was stuck in bootloop and it did turn on by itself after forcing shut down.
What I did to fix it:
1. I've waited for battery to discharge
2. I've downloaded and installed on my PC:
- LG UPPERCUT - Download here - XDA
- LG Mobile Drivers - Download here - LG.COM
- Android Fastboot Drivers (not necessary needed but i wanted them just to be sure) - Download here - drive.google.com
3. After that I went to search for stock KDZ for my model and my region here (lg-firmwares.com)
4. When everything was downloaded and installed I took my phone and while holding Vol+ I've connected USB cable to my phone (make sure the second part is connected to PC before pluging in to phone) and after few seconds my phone booted into Download Mode
5. Now you need to run LG UPPERCUT - if your phone is listed in upper list then you good to go and if not, check your drivers and errors in Device Manager - select your KDZ in "BIN File", change checkbox from "REFUBRISH" to "UPGRADE", click "Start" and wait.
Your phone will reboot few times but after hitting 100% in Uppercut it will take 2-5 min and boot to stock OS!
