Hello,
Today I didn't notice that I need to charge my phone, so it eventually turned itself off. Later I knew I received an important SMS that I wanted to check but I didn't have the charger at hand so I tried to turn it on twice. Both times the Mi logo showed up, then the phone immediately turned off. The 3rd time I tried to turn it on, nothing happened.
When I was finally able to connect a charger, nothing happened. The screen doesn't turn on, the Mi logo or battery logo doesn't show up, the small LED doesn't react either. The charger was heating up so I knew something is happening so I left my phone there. When the charger started to cool down I knew that the charging is done, so I tried to turn on my phone again but nothing happened.
I have TWRP 3.3.1-0 and LineageOS 16.0 20200422 Nightly installed.
I have tried to press Pwr+VolUp but nothing happened.
I have tried Pwr+VolDn and FASTBOOT showed up. From here I tried to reboot by holding either Pwr or Pwr+VolUp or Pwr+VolDn.
By holding Pwr+VolUp or Pwr+VolDn the device turns off.
By holding the Pwr button, the Mi logo shows up for a split second then the phone turns off.
At this point I stayed in FASTBOOT and connected my phone to my PC and tried to use the Flasher Toolkit Nikel V3 (the tool I used when I installed TWRP and the custom ROM and whenever a LineageOS update bricked the phone) to reboot or boot into recovery, TWRP.
The phone doesn't react to any commands which is really strange, never had this issue before.
If I try fastboot boot twrp-3.3.1-0-santoni.img I get the error "unlock device to use this command." Which is really really strange because I had it unlocked before.
So currently I cannot turn on my phone, I can only reach FASTBOOT and nothing else. My main goal would be to backup data (photos etc), reviving the phone is only secondary.
I was searching the whole day on the internet and couldn't find anything that helped.
Any help is highly appreciated.
Try charging with different USB and charger.
Also you may want to remove the back panel and disconnect the battery connecter from motherboard and reconnect it after few seconds and try charging with charger.
Proceed carefully if you wish to remove back panel in order to not damage any device components to be precise the fingerprint flex cable which is glued to back panel.
This is what helped me to revive my phone but I couldn't find any trusted stock ROM sources so I installed a stock ROM from androidmtk.com and xiaomistockrom.com.
Can someone please tell me if they are safe or not? And if not, can someone please link me a Redmi 4X stock ROM I could use with the XiaoMi Flash Tool?
Also, it seems the phone cannot detect anything in the 2nd SIM slot. How can I fix it?

Hello All
I did search the forum and still not answer for the stranger reboot loop.
I got a phone call, and answered it. The reception was crappy and hear no voice. I then looked at the phone to see if call had dropped and it was frozed on the incoming call screen. I then pulled the battery and pressed the power button to turn on the phone and It would not power on. After multiple battery pulls and many many power button presses, still nothing. It was like it was out of battery. It was stitting on the home charger before i left the house. Prior to this the phone worked fine. Over the past week or two I had to do a battery pull may be 3 times.
I got to my car and plugged it into the charger and the orange charge led came on, on the front of the device. I then pressed the power button and it vibrate once as normal and then went to the multi-colored nexus "X." he screen went black and then vibrated once again and and was back at the mulit-colored "X." Then the loop starts.
In between the restarts I try to get it to boot into the bootloader by using the "vol down and power" and the "trackball and power button" and the white screen for the boot loader flashed for a milisecond the goes to black. As long as I hold the "vol down" button the while bootloeader or recovery screen flashes every 4-5 sec for a milisecond. As soon as I let go of one of those button, it automatically goes to the full reboot loop.
THis all happens when it is plugged into a power source. As soon as i unplug it, it goes back to the power button not responding. Again it acts as if it has no battery power. But it is in the 90%.
So i am unable to do any other step as in reflashing, and or doing a recovery.
ANY IDEAS any one.
I was running Cyanogen RC3. the latest rom with amon RA 1 7 1, korean radio 5.0.8
It was running perfectly up till today. when it went into its loop.
ANY HELP WOULD BE AWESOME
THanks in advance

Plug it in to the USB, adb reboot recovery, reflash rom. Or even wipe and reflash if needed.
Sounds like it could be hardware the way you have to hold the keys down and you said it wasn't responding to the power button press.
ok thanks, ill give it a try.
here is my only issue. I am not using my original computer Mac. I just sent it out to apple for repair. So i am using my companies computer. I need to set up the AndroidSDK to be able to talk to the nexus. Since the phone will not turn on i can not load the drivers. and ive tried every way and it has not installed and i cant check because it wont stay on. it just goes to the loop. and it wont turn on if its not plugged to a power source.
Any ideas or suggestion.
SOrry I am an noob, so could you please be specific in your instructions.
I as of right now have insalled the Android SDK and i am unable to see the serial number (working on an old dell, running XP sp3) because it wont turn on.
It cant manually install the drivers because I cant turn the phone on to specify the drivers.
and
I using USBDeview, the phone also has to be on to erase all HTC previously installed drivers. i think. but there were none in the usb log...i think becuase they didnt install...agains because it would not power on...:-(
any ideas...please
DD
Also
Sorry excuse me if its a sort of a duhhh question...
even if i am able to load the device bridge, if the phone will not boot can i still flash another rom, or do a recovery. The phone is not getting past the Multi-colored "X" ???

It should still read the commands when it's trying to boot. You don't need to turn the phone on at all to be able to install the ADB drivers, they are independent of each other.
As strange as it started, is a strange as it went.
This morning open the phone to pull the sd and the sim to put it in a throw down phone. I replaced the battery and cover and just hit the power button. The phone does a full boot and it appears to be working properly. the sd card and sim are fine. I the odd thing is i did this multiple times yesterday and last night. I pulled both sim and sd, replaced the battery and tried to boot with the same issues as named above with nothing different.
I left the phone on charge last night and it was charging for close to 8 hours and it was still showing the orange charging light.
So after it booted this morning, and i checked everything. It showed the same amount of charge as yesterday, right before it froze, which was 75%. So that is another strange occurance.
I plan on reflashing the rom and seeing how things go.
I thank you for your assistance and time.
appericate you helping out a clueless noob.

[Q] Bricked? Stuck on either white AT&T screen or grey, frozen battery screen, no USB
While trying to install Cognition v2.2b3 via Clockworkmod (from stock at&t 2.1 froyo) something happened mid-install and my phone ended up rebooting, and I have not been able to turn it on since.
-When attempting to power on normally, phone shows white AT&T screen and hangs there
-When attaching USB, phone shows battery screen but battery is all grey and rotating progress icon is frozen. Does not appear to be charging.
-Computer does not recognize phone in any state. Latest USB drivers are installed and I have had no issues connecting via USB previously.
-Cannot get into download or recovery mode using any volume/power button combination or through adb. Also tried attaching USB with ODIN running while attempting button combinations, inserting/removing battery etc, still nothing.
Has anyone else experienced this? Anything else I should try?

Click to expand...
Click to collapse
Go into Download mode, hold both volume buttons down and plug your phone into USB. If it doesn't work than pull the battery and try again.
If that doesn't work keep trying until it does. I'm serious, it took me like 40 tries last night to flash stock with the 1 click and then finally get cognition running (that only took one flash)
Odin is a piece of crap, it works maybe every 10th time for me. I've never used the rom manager to install roms, always use clockwork recovery. Less to go wrong if your in recovery mode I suppose.
But literally just keep trying until it works o.0
Hi. I've experienced exactly the same this night. Try this: forum.xda-developers.com/showthread.php?t=775911 it helped instantaneously.
BTW, you really need to wait at least 10 secs after removing battery.
I have the exact same problem.
My battery screen shows up with nothing but a flash loading icon and a grey battery. When I simply turn my phone on its stuck in ATT boot screen. I tried the instructions many times trying to get into download mode but right when i put it in the battery while holding down up/down/power it simply just shows the "frozen battery charging" screen again.
HELPP
Well along with the entire world it seems I've done something wrong trying to get 4.3 on my phone. I've been around the block a few times, so I've done all the expected things, but my phone is stuck at the White HTC screen and won't turn off. When this happened the phone was in S-OFF, Relocked, and I was trying to flashback to stock 4.1. Holding down the power button or power button + volume down does nothing but flash the lights. I've held them down for 2-3 minutes with nothing but flashing, no reboot. Hooking the device to the computer recognizes the phone as an MTP device but I think that's just the default for a powered usb port.
With the usb cable connected, the charge light does not come on so it will eventually die when the battery is expended. I don't know that it will recharge, which may be good if I'm going to get sprint to swap it.
Any suggestions?
OK. So I was actually able to get the bright light trick to work, but now I have the issue of trying to get an OS on the phone. TWRP fails ADB sideload because it can't find /data and it won't let me check the mount box. Is there a way to fix the partitions?
Thank you for the PMs everyone. I've got it under control!
Sorry for my bad English
Hello friends of the forum, I present my problem. I was given to repair a S3 LTE really is driving me crazy. We'll explain: the owner did filth with ROM to the point to make it unusable. Turns on, but after a while it stops and turns itself off. I tried to flash the stock, wipe system etc .. from recovery and put back the stock, but every time I turn on the phone and get to the Initial Setup (the one that says Samsung GALAXY which allows choosing the language) crashes and off. Also known that the recovery is very very slow (both TWRP that stock that cwm). I managed to flash rom 2 including Cyanogenmod but this crashes. Sometimes the poor cell can not even start that hangs on and off. I tried to replace the battery with one that I already had and the situation does not change. I wanted to try to do an update of the bootloader because I think the problem is the. Further inform you that when it crashes but is charging if I remove the battery on the phone stays on but completely locked and I can not even press the power button for 3 seconds, because it is completely freezed. Another observation I have noticed is that if I leave him in charge when switched off the led solid red, the screen shows no signs of life and if the detachment micro usb LED remains lit sign that is completely blocked even when it is charging (WHILE TURNED OFF!). I hope you can help. I tried everything
Maybe it's power button problem.Check the power On/Off .
My phone went to an endless bootloop after a botched attempt to install TWRP. I tried hard pressing the power button to no avail, and I can't access fastboot either. That's why I removed the back cover and disconnected the flex cable from the battery on the phone's motherboard.
Later on, I reconnected my phone's battery after my shift ended, then I tried to flash my stock rom through SP Flash Tool + bypass tool python script and it went through with a success. However, this time, my screen seems to be completely dead but my phone is still showing some signs of life (short vibration when pressing the power button, but since then it seems that it takes a few seconds more from pressing the power button to turn it on. ) I reconnected and disconnected everything to see whether or not I missed out something but the issue still persists.
The computer reads the device as "Android ADB interface" and the adb console reads it as *device id* unauthorized when I ran adb devices command. There's no notification light whenever I plug it into the charger.
Is my screen dead, or is my motherboard toast? I need to know as I don't want to spend money to buy a replacement LCD only to know that the motherboard's dead. I don't really care about the IMEI as I'm just going to use it as an authorization device for work. I can just always connect to Wi-Fi. Please advise.
One problem after another, so it seems.
Turns out I already unbricked the phone, but the thing is that my display's backlight got busted for some reason. Unless I shine a flashlight through it, I won't know what's in the screen. I'm currently on the way to get a replacement screen, and a new battery cover.
I guess this will be the last Xiaomi device that I'll ever get. This is the only time that I experienced such flimsy build quality since the LG G4.
Maybe you have destroyed a lil cable or something.
