Dear fellow XDA members,
Yesterday, I replaced by LG G2 screen and after the repair the phone wouldn't boot anymore. It however shows signs of life if I plug in the charger, this is what happens then:
Notification light blinks 8 times red
Pause
8 times a red blink
Pause
and this continues for ages.
What I did sofar:
-Tried to soft reset & hard reset via button combo (no result)
-plug out the battery connector & plug it in again
-check all connections and possible damage (no potential problems found)
-Check voltage of battery (it is around 3V)
-Put phone in charger for a whole night
Do you guys have any ideas what is causing the problem? what does the 8 blinks error code mean? Hopefully you can help me out!
that sounds like the new screen is damaged.
try the old one and see if it boots
i dont think that it has anything to do with the battery
no idea what the led error code means
Not working.. Also replaced battery, but still same blinking led
Hi! Similar problems have been posted on the forum before, but none of the solutions worked for me.
Stock Mi A1 with vanilla Oreo (latest official patch), everything stock & vanilla, no hacking, no rooting, no modifications etc whatsoever. All apps installed through google store, nothing fancy.
In short: put my phone into airplane mode about a week ago (battery at 90%), then a few hours into the flight the phone blacked out. Won't react to power button, power+volume up, power+volume down, all buttons, no buttons, any combination of buttons for any length of time. Phone was in my pocket, no physical impact or anything, just "died".
There are 2 signs of life:
- If i plug it to charge the notification LED blinks about 1 / sec
- If I connect it to a computer, it recognizes it as Qualcomm 9008 blabla device.
What I have tried so far and didn't work:
- All imaginable button combinations: no reaction
- Fully charging phone: doesn't help
- Letting battery deplete: doesn't help
- Disassembled the phone, disconnected the battery, put it in charger, reconnected the battery: this fixed the issue for some, didn't work for me.
I GUESS that since the computer recognizes it I could try to "flash" it or whatever, although 1) there are a lot of negative posts about it 2) I have no idea how to do it (which exact ROM, using which exact tool, etc).
I wouldn't mind not losing the data on the phone though, if that is an option: I was about to back up my photos on the flight, but it died before I could have done it.
There is no official Xiaomi support / service where I live, bought the phone while visiting a country which sold it.
Any suggestions?
Small update.
- adb doesn't see the device.
- Miflash sees the device, but dies at "ping via firehose" stage.
-A1 low level backup tool doesn't see the device.
After 2 weeks of googling I have found around 50 forum threads around The Internet with similar issues, but no solution as of yet. Sounds promising!
I had this problem 2 hours ago and fixed with the Disconnect battery, connect charger, reconnect battery (while charger is still connected just to clarify). you tried this fix like this? reconnecting battery while charger is still connected?
Maybe try getting a different battery and connect it, and/or maybe let the battery discharge itself.

Thanks for the replies fellas. I have tried this before. Now I have tried this again just to be sure. Did it multiple times. Disconnect battery, connect charger, reconnect battery. It doesn't alter the phone's state in any way. Doesn't react to buttons, flashes led on charger, shows up as qualcomm 9008 device on PC, but doesn't let me flash anything. Sad.
Qualcomm 9008 is sigh of faulty emmc chip. Bad soldering i guess. Take the device to the service center. My 1 cent op. Regards
Its very simple the solution. The problem is the cable. Try to change the cable, charging the phone and turn it on. I my case works

Have you had any progress? I'm having similar issues with my mi mix 2s.
The answer is to replace the battery. I have two dead batteries for my Mi A1. Both batteries were left in the drawer for several months and upon connecting them to my Mi A1 they showed the dreaded blinking light. After trying to fix this for a day I gave up. I disconnected the battery, the phone booted up right away. Bought a new battery and everything is working again. Hope this helps!
I too had numerous kind of hard bricks with my previous smartphones.
Here are the links that will save your life:

Link 3
Try the ones that you think fit the most.
I had the same issue just today
removed the battery connector and connected it back without touch any other component
phones working fine now
its bricked and get into edl mode just try to flash with MiFlash tool i have faced this problem some time ago when i flashed an ota with twrp recovery then my phone went dead and when i connect it to pc led blinks and phone recognise in ports as "diagnostic port 9008d" something like that then i install the drivers and flash stock pie rom with MiFlash tool but after successful flashing phone wont boot but after pressing power button for 10 to 15 second phone starts. i have unlocked bootloader so it works for me but i'm not sure it works on locked device try it or use QFIL flash tool from QPST
This happened to me but all i did was charge the phone the whole time.
My Xiaomi A1 had the same issue, I think I have tried all available solution but unfortunately mine still dead, and when I connect the charger it blink.
I guess the ultimate solution is to throw it to a recycle bin.
I've recently installed OrangeFox and changed my system to Android Pie, so far it were amazing. Just got to my knowledge that MIUI from other phones was ported for this phone, featuring Android Pie on MIUI for Redmi 4 Prime.
I've installed it and rebooted, so far so good everything was working on first boot, but got many Force Closing apps (including system ones) and decided to do a factory reset, booted to recovery, did the reset and rebooted, phone died. Nothing happens, no charging when plugged, no USB recognition on PC, no Turn on even after holding Power button for over 30 seconds, no fastboot, NOTHING.
Opened up the phone, measured the voltage of battery, 4.14V so it's normal. Tried to fire up the phone using an adjustable DC PSU, set to 4.0V and no amps were drawn from board upon pressing power button. So now my phone is dead. I don't know how or what caused this.
Searched the internet for schematic using keywords like markw, hongmi4pro, HM4Pro, HM4, Hongmi 4, Redmi 4 Prime, Redmi 4 Pro, but I can't find it anywhere, it's like this phone never existed for maintenance, lol.
With the phone schematic I would be able to figure out the path power makes and what kind of IC, capacitors or resists to check in order to replace. But I don't know where to look for it anymore.
If someone have it, please share with me. :crying::crying::crying:
Hi, friends. This is my first post here. I read many guides and opinions here. Thanks. Now I have a question...
My Redmi Note 4x Snapdragon Global shows a blinking red light when connected to a charger (even the original one that came with the phone). I tried removing the battery and connecting the phone without it. Then I reconnected the battery but it didn't work. The MI logo never shows up.
It started some days ago. My phone's battery was totally dry. I charged it and it booted normally, but then turned off by itself. When I tried to boot it again, it showed the MI logo for like an hour. Then I pressed the three buttons (Vol. UP, Vol. DOWN and POWER). Then, the logo disappeared and now I'M STUCKED in the blinking red lights.
I heard that this is EDL mode... I guess. I have to flash my phone... But I heard that there is some way to keep my internal data. I don't care about my applications. I just want to recover my pictures and my videos.
I have my MI Account, my Google Account, etc. This phone is totally mine.
It doesn't turn on so I can't remove the password.
I read that if you make contact between some pins in the mother board and connect the phone you are going to be able to flash it directly. BUT... Does it wipe out all the data?
I heard that if you remove the password setting or if you simply don't wipe out everything the internal data should be fine. But I want to be sure.
Please... Is very important that I keep those files. Thank you very much. I'll wait for your answers.
Hello everyone, initially sorry for my English, I use Google
Method 11-16-2021
My case: after a MIUI update it crashed, the symptoms: it did not turn on, it did not enter Recovery, it did not enter Fastboot, it did not load
What I did initially: I googled all the possible methods and none worked, it just worked to disconnect the battery so that at least it would charge; then I found the solution to let the battery drain completely and recharge it until it turns on to 100%, but it was still stuck on an infinite reboot. I left the 4Gb / 128Gb equipment for 7 months for lost, I tried to contact the warranty without any response ... Note: never use temperature methods for the chips, nor for the board, nor jumpers, anything electronic.
If you recognize by usb on the PC, the driver: "Qualcomm HS-USB QDLoader 9008", then you need to do this:
The solution:
1- Simply disconnect the battery and the flex from the screen and then reconnect them.
2- Now leave it like this for 8 days (8 because 2 or 3 does not work, in my case it does not work) until the battery is completely discharged (you should not do anything else, it will discharge itself)
3- After 8 days, connect it to the original charger and let it charge for 5 minutes, without disconnecting the charger, click the power button and it should turn on normally as if nothing had happened; I know it seems like a funny or stupid thing, but that method worked for me, maybe it was luck, I don't know, I had been fighting for a solution for 3 months, I just wanted to enthusiastically share this solution before they damage their mobile phones by doing experiments with their motherboards. I wish you luck.
Note 2: the phone was only discovered to release the battery and flexible screen, nothing else for that, ok
Update: 12-17-2021
It cannot be turned off because it returns and does not turn on or load, nor does it restart; But after this, simply disconnect the battery first and then the screen flex, reconnect them and it will turn on without any problem. It is a temporary solution that works perfect for me while over time I know what the real problem is if it is hardware or software
