Rn7 global died all by itself - Xiaomi Redmi Note 7 Questions & Answers

The phone rebooted by it self, no firmwareupdate going on, just random reboot.
Got stuck on redmi logo.
Could reboot and get fastboot, but could not flash original fastboot rom, got errors. a normal reboot gave only redmi logo.
Now the phone is out of power, not taking charge, not powering on.
Anyone have any solution for this problem? Or any tips? The phone is stone dead

Not sure if this will help...
here's my random reboot thread and fix

Well, i have no simcards or sd-cards inserted.
And its not charging or turning on. volume up and down + power is not making any results.
The weird thing is that it said "redmi" on the display for about 24 hours draining the power, and after it died out of power i'm unable to do anything with it. its basically a brick.
This happened totally random. just a spontaneous reboot into a never ending redmilogo.
During redmilogo i had the posibility to get it into fastboot by rebooting it, but mi flash would not accept the phone. so another reboot into regular boot ended in infinite redmilogo again :|

Your phone's bootloader unlocked?

Nope

Did you try keeping it charged for a while? Device might not show any sign (charging indication) but the battery will get charged eventually (I guess).

Charge it well and try to SIDELOAD that FASTBOOT IMAGE via PC..

It loooks like its bricked all by itself. i left it in charger for days.
I got contact with the phone with mi flash, but it has gone into some authentication mode with the flashing, so i'm not possible to reflash rom without authorization.
Read about this on reddit, and it seems like a dealer has to look at it.

faulty motherboard or faulty battery ?

Hi, i have i tilapia 32 gb with latest bootloader and i used it during the last 2 year with a slimkat rom.
Now almost everytime it won't turn on normally. The screen is black ,i can't get into recovery or bootloader and charging the battery does nothing.
If i connect it to a pc ,first it shows apx mode on device manager, then if keep pushing the power button many times sometimes it starts and i can access to bootloader and recovery.
I wiped everything,flashed twrp again,tried other roms but almost everytime it won't turn on normally even if the battery is fully charged.
Do you think it is 100% a motherboard problem?
Is there some chance that replacing the old battery(i never changed the original one) will solve this problem? thanks
Most likely storage finaly died so you are out of luck

Redmi 2 doesnt turn on until and unless it is connected to a charger.

Hey Guys,
My phone gets stuck in a bootloop if I don't use a charger while turning it on. Actually, doesn't even get past the splash screen and reboots every 1 to 2 seconds. I also need to connect it to the charger to access TWRP. Normally, when I disconnect the charger after the phone has turned on, the phone suddenly turns off. But when I do the same when I'm in TWRP, nothing happens and I can continue using it without any problems. I'll put the logs if you neeed. And yes, I don't need the charger to get into fastboot mode. I'm currently on lineage 15.1 unofficial but the problem persists over other roms too. Please help...
Change the battery
It's the battery , which is under performing with the voltage needed to run the rom process,
That's why you are able to use with charger and got bootloop without charger. In twrp or any recovery mode most of the hardware is disabled and does not need much power.

Nexus 6P stuck at bootloop again

So the thing is the phone can not be turned on while not being connected to a charger or USB on PC no matter how long I charge it. The phone bootloops after it is tuned on. I can enter bootloader but not recovery mode. It boots again once I try it.
Quick catch-up:
The battery was once replaced. After some time the phone started to bootloop. I fixed it by unlocking bootloader (by heating up the phone to get past the bootloop) and flashing a stock factory image after that. It worked fine for months until yesterday.
Anyone knows if this can be somehow fixed?

Le Pro 3 - Stuck in a bootloop recovery mode and fastboot not working.

Hi guys,
After googling it I tried booting it in recovery and fastboot mode but none of them work, when I try to boot in those 2 modes I get a screen with "recovery mode" written for 5 secs then it goes back to the normal boot screen and then turns off and starts to bootloop again the only way I could stop it from boot looping was by pressing the power button + the + and - buttons, so yeah if you guys have any idea how I could fix this or how I could recuperate my data please help, also it started bootlooping during the night while it was charging it was very hot when I took it, last thing when I try to go and charge it there is not indicator that it's charging.
Thanks in advance for your help !
much love
Mathias.
Kind of the same issue here.
Yesterday, I was using my phone while it was charging (low battery), and suddenly : freeze then power off and stuck into a bootloop.
It did it all the night until no battery, now when I plug it the charging Led is not lighting, and stuck in a bootloop.
Tried to flash TWRP vi fastboot mode : success but impossible to boot into recovery mode, as you described.
Affraid of the battery has died...
Flashed wrong orange state zip
Same to mine, my device was x651 and i flashed an orange state zip file intended for le 2 x620 without wipe and after flashing it from recovery , I rebooted the device, now its powering on and off on a dead screen and only long vibrates, how can we fix this? Please help
Not sure if this will help, but I ended up with a perpetual boot loop on the phone and wrote it off as broken and got a new one....a year later, I plugged it in to see if it would even power on so I could trade it in and VOILA, it boots up! What the hell? So my suggestion is maybe to let the battery run ALL the way down and then a long charge first.

Is my stock H910 truly a brick now?

TL;DR it's bootlooping, and I can't enter download mode.
My V20 H910 hasn't been touched for a couple years now. It started bootlooping years ago, and it's only now that I'm trying so hard to fix it. When I try to boot it, I get the LG screen for a few seconds, then it goes all black, and then it repeats until I pull the battery.
I can navigate to the screen to initiate a factory reset, but when I confirm, it freezes up for a moment and then goes back to the boot loop.
When I plug it in to initiate download mode, I get the screen that says it's trying to start download mode for a couple seconds, and then it goes back to the boot loop. I tried launching LGUP during this two second period, and unsurprisingly, it does not see the phone.
I've tried putting it in the freezer, and I've tried using a different battery. I tried "discharging the capacitors on the motherboard" by removing the battery and pressing the power button fifteen times. This causes it to vibrate briefly when I attempt to power it on, but then it bootloops as normal.
It's totally stock Oreo - no root, no custom ROMs, no TWRP, no unlocked bootloader. I might have enabled USB debugging, but that doesn't do me much good when it won't boot (yes, I tried ADB anyways, and no, it doesn't see it).
I did use third party USB cables to charge it back when it worked, so I am aware that this may just be a faulty motherboard. But I'm hoping there's another option I haven't pursued yet.
What do you think? Is it a brick? I've spent all day searching for potential fixes, so any help is appreciated!
