I I bought the phone from google 1 week ago, in the early days works well. But then when I flash franco kernel finds phenomenon if I do not connect with computer or charger, the phone crashes, I tried to flash a different kernel, flash CM.10 still crashes when not charging or connecting to computer. I also tried to flash stock and unroot, but still did not fix the error. I now no longer in the U.S., so I can not warranty equipment.
I think my battery is fine, when i discharging, cpu-z show battery 3940mV, but 3 minutes later the phone hangs, the sreen still on, and it will on until battery down, but no response when touching, push button or connecting computer again.
I really need the help. please
Hi,
I have a problem with my Find 5: I am stuck in a bootloop. The Oppo logo appears and after only a few seconds disappears, the phone vibrates and then the logo appears again. And this goes on and on.
I can get into recovery and fastboot but the real problem ist that my Find 5 will turn of again after maybe one minute into recovery. I tried it with CWM and TWRP. When I want to turn on the phone or get into recovery without being charged, nothing happens.
Before that I haven’t used the Find 5 because the USB-Port was broken and it would not charge. Even if the phone had a connection, its battery percentage would not increase at all. Then I ordered a new battery and a new USB-Port. I installed the new parts and suddenly the phone started to work again. I flashed a new nightly of CM 12 and installed some apps. The next day (it was charging over night) I unplugged the phone at 30%.
When I looked at the battery chart, I could see that the battery percentage did not decrease and also not increase while plugged into the charger. Then after some normal use, the battery percentage jumped from 14% directly to 0% and the phone turned off a few seconds later. When I charged it, it was stuck in a bootloop again. First it took about 30 seconds between the reboots and after the Oppo logo disappeared I could see that it i charging but after some minutes the reboots got faster (every 8 or 9 seconds).
So I am having the same problems with the new parts again but I don’t know why because it worked for some time…
It seems that the battery is broken again but how can it be? It was a brand new battery and it worked for one nearly full charge. Are there some common mistakes when replacing the battery that I could have made to cause my problem? I don’t know what to do and I want to try everything that is possible before getting a new phone.
Edit: Now I know where the problem is (or where it is not) but I have no idea what to do against it. The problem lies somewhere in the mainboard. Because when the charger is plugged in the phone will start to reboot again and again so the cable between USB-port and mainboard should be ok. But the battery is not charging. The phone worked with the new battery for a while because it was already charged when I built it in. And now since the battery is empty again I am experiencing the same problem as before again.
So does anyone have an idea? Where is the exact problem and can I fix it without spending much money on it?
Thanks for your help

Hi there,
My Note 4 started playing up 3 weeks ago, it started to lag, freeze and reboot. I managed to bring it back to function as my daily driver (handy as I didn't have another phone!) with the Wake Lock app. Sometimes when I'd try to boot it up, it would be glitchy and it would take a while to fire up again, most often I'd have to boot into TWRP and wipe the cache, but then it would be fine. The wake lock app was set to auto run and all was good, apart from a major hit in battery life.
Today I started to set up my replacement N910F (bought used). It too was running stock MM, I'd rooted this one too and installed xposed. All was going well until I went to remove the sd card from the first phone. When I went to reboot.....nothing.
I tried to remove the battery and hold down the power button and then try again. Nothing. Tried holding down the power button for a few minutes with the battery removed and then trying again. Nothing. I even tried holding it down for a couple of minutes, putting the battery in for 10 mins and then trying to power it up. Nothing.
It doesn't show up on my PC or with Odin. Nothing happens when I plug it into the charger. I've tried 3 different batteries. All with the same end result. Nothing. :crying:
Is there ANYTHING I can do?

Could be battery is dead or your device is hard bricked.
You might wanna see link below to unbrick method

It's not the battery as I've tried the 3 that were working with the phone originally, and I've just tried the one form the "new" phone.
After looking through the link, that doesn't look like an option - the phone needs to be detected by the pc. Mine was connecting fine earlier, so I know it's not a lack of drivers. I makes a noise when plugged in, but then isn't shown.

It should be detected in device manager under ports section.
If the pc makes a sound when the device is connected, that means the device is fine. You can try the debrick method given on my thread.
Try it and report.

Don't ask me how but.....it suddenly came to life this morning! I put a battery in it and tried to go into recovery, and voila! No rhymne nor reason to it but she's up and running for the mo!
Thanks for the suggestion yashthemw but thankfully I've not had to try it!
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:

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.
So here the deal guys , my mi 9t pro is about a 18 months old and recently started to have issues with battery life (long story and since I wasn't personally using it I can't explain the issues very clearly but it was all over the place doesn't charge at times verified the charger was indeed charging another phone , sometimes the phone turn off when the charger is connected so quite a lot of erratic faults and no consistent issue to point out )
I have been trying to look into it for a week now and this is my observations.
So first and foremost the phones does not turn on ,meaning that when just the power button is pressed it is stuck on the boot screen with just mi displayed on the screens and does not change at all even after hours.
I did find a way around it when I send the phone to recovery mode by pressing the volume+ and the power button and then selecting reboot and reboot to system. This way the phone always turns on . How long it remains on is a different matter some times it a few secs while at other times it could up to 10 mins and most of the time if its plugged to a charger and I disconnect the charger it immediately turns off.
Things that I have tried
Firstly, I had suspected the battery but on opening the rear cover realized that the previous battery looks in extremely good shape additionally I connected the new battery but connect the cable and realised that the fault persisted.
Thinking it was a software issue I also tried to flash the latest MIUI version from its official website with no help.
Now I am certain the issue is with the circuit or with the motherboard.
Any previous experiences and how it was fixed could be helpful .I don't mind doing some troubleshooting myself and can arrange for advance tools if required.
In short would appreciate advance level help as I enjoy fixing these things myself.
TL;Dr my phone is behaving quite erratically and having tried the battery and software need help repairing it.
