[HELP] Redmi 4x won't boot. - Xiaomi Redmi 4X Questions & Answers

Hello,
my Redmi 4x won't boot. I tried to find some solution for this issue, but I can't find it anywhere, so I created this new thread to ask you for your help.
Last night I was out in the city and my phone died because of low battery, so after I came home I just wanted to charge it as usual. Battery logo showed up and it was behaving as always, but when I tried to turn it on it couldn't boot again.
After pressing the power button the splash screen flashes for a brief moment and then it just turn off again. This happens all the time from the moment my phone died. I'm not sure what went wrong here. I can't get it to recovery mode either. So I wanted to do a fresh start and flash it again with new ROM here (Ressurection Remix 6 is what I have now)
I'm able to get it on fastboot mode, but once I try to flash it with MiFlash I get error message like "error:FAILED (remote: Critical partition flashing is not allowed)"
So I looked up for a solution and I found that I need to get it in EDL mode with adb.exe
I tried this solution but with no luck. Phone is restarting but it won't turn on again and the fastboot mode is lost.
I'm not really sure if I have right drivers for it. Qualcomm HS-USB Diagnostics 900E is what I have now. I can't also change the usb debugging mode obviously, so I'm also trying to find some solution for this issue either (is there any chance how to turn it on with adb.exe?)
I think it's softbricked but i'm not really sure.
Thank you for your help

Hi, most likely your battery is faulty. Current draw during Android kernel boot up phase is above 1A whereas only around 0.2A for a working OS, that's why neither OS nor recovery can start when the battery develops high ESR (internal resistance). Do the following test:
fully recharge the battery
do not disconnect the charger
turn it on
Your Android may now actually work again but you must use a short quality cable connected to a 2A+ charger, which will support the battery at boot time - and you can disconnect it later.

Thank you, but the battery wasn't the main issue, because once I was able to flash it through EDL mode to the latest stable official ROM, the battery was on 93% already.
Now I'm stuck with MI logo and powered by android with 3 blinking dots above. I watched somewhere, that it could last for 7 minutes, but for me even the 15 minutes is not enough, so I guess i'm in bootloop.
For some reason my bootloader is locked again, even though I already made the unlocking process earlier before I flashed to Resurection remix 6. My phone doesn't even appear in device manager. I can't even use it as a storage, so I could try to flash it to custom ROM.
I'm not really sure wat happened and how is it possible to brick your phone by just draining your battery to 0%

Ok, phone is alive again. It booted up right after I inersted microSD card in slot. I didn't know this was necessary...

Bootloop & empty battery

Hi.
I've been searching for a solution on how to fix my phone for already almost a year now. I didn't even do anything to it, no custom recoveries or OS (wanted to get CM, but at the time it wasn't available on it, not sure if now is).
The problem - the phone is stuck in a bootloop with an empty battery. The battery wasn't empty at the beginning, but it died in the process of trying to make it work, since the only thing I can boot is "fastboot&rescue" mode, in which the phone doesn't charge - how sweet. Now, I've read just about every thread here on how to flash custom (and original) recoveries, all the DLOAD folder versions and everything, and somewhere in between all that I found that it's impossible to flash anything if the battery is low (or totally empty).
The question - how do I charge the battery if it doesn't boot in anything other than fastboot, and when I plug it in the wall it just loops and loops and loops, and doesn't even charge? It's also impossible to turn it off while it's plugged in the charger. WTF, Huawei, really?
Any help appreciated. Cheers,
Can you Boot into recovery through pressing power + volume+?
You may have to remove the back of your phone and buy a new battery. The disassambling process is pretty simple, but of course you will loose any guarantee..

No, can't boot into recovery, only fastboot. If I could, I guess I would've already fixed it, heh.
I actually got it to charge, at least that's what I think. There was a *.bat script somewhere here that was repeatedly doing these two things:
1) fastboot getvar battery-voltage
2) fastboot reboot-bootloader
So, I ran that (while the phone was plugged in my computer and running fastboot mode), and it began looping and looping and looping. Left it like that for the night. Now, in the morning, when I unplugged it and tried to do someting, the red "battery low" LED wasn't glowing/blinking anymore! Since "fastboot getvar battery-voltage" returned an error all the time (remote: command not allowed), I don't exactly know how much power I have in it, but I'll just leave it like that for a day or two now, and then try some of the methods I've already tried before. Got any new ones I could try?
I already removed the back and removed the battery - wanted to see if I can charge it externally, but has a very small connector to connect it to the mother board, and I can't just put it in any external charger - I actually didn't find any external chargers that can charge the battery of this phone, really strange.
About the warranty - don't even care anymore. Somehow I managed to get a small crack on the glass on the back of the phone just a few days after getting it. Screen is not damaged, just the back cover. And, you don't know Latvia, but this is how it goes here. I took it to a repair shop - the one I needed to take my device for warranty repair. However, in Latvia that means it's just an another small repair shop, which just happens to have a contract with the company who sold me the phone (mobile phone operator). So, they take my phone, say they'll do a diagnostic and get back to me. Three weeks pass, and they call me telling that the only thing they can do is replace the motherboard, which is gonna cost me about 250 euros. That, or nothing. I don't agree. That means, if I don't agree to their suggested method of repairing, I have to pay for the diagnostic (about 20 euros).
Well, good idea, looks like you will get your phone running..
To unbrick your device you need to flash a recovery that matches with the firmware you had been on. So, if you had a B1xx Rom running try flashing TWRP 2.8.1.0 and MyRom 1.2. After that flash the stock emui 2.3 recovery and B133 through dload. If you were on a B6xx Ron flash TWRP 2.8.7.0 and MyRom 3.3, then emui 3.0 Recovery and B621.
When you didn't try this way until now, do it. It should work if the device isn't hardbricked.. I wish you the best.

Just flashed TWRP 2.8.1.0, it's already getting better. Now when I tried turning it on in recovery mode, it's not just simply bootlooping all the time, but is stuck on the Huawei logo. At least I hope that's better If I try to turn it on normally it just bootloops again. Omg omg omg.

Well, tried everything again. Flashing all those recoveries, nothing, can't get a recovery. Put a dload folder with update.app in it, magic 3 button combo just gives me some more of that good old bootloop. Extracted everything from the update.app, flashed recovery, system and boot with fastboot - all showed success. I got the most excited when it got to flashing system - it was quite big and took quite long, and returned success, so I really hoped that really did something - but no. Downloaded P7 kernel. Tried "fastboot flash:raw boot P7_kernel" ("P7_kernel" is the name of the file). It created a boot image (544985088 bytes), sending 'boot' returned "OKAY [20.622s]", then "writing boot" returned "FAILED (remote: flash write failure)". Is this the thing that's really broken? The boot flash partition? If so - what can I do, if anything?
God I hate this phone. The best is that I only used it for 3 months, and I still have to pay for it for more than a year. It's been in this condition for 7-8 months already. FML.

Hi. Yes, bootloader unlocked, 100% sure. Have tried flashing the stock recovery, no changes. Tried to find the b135 now - I actually failed to find a real, valid download link! All I found were some russian ****up sites, which downloaded some russian ****ing malware! WTF? I'm about to give up on this phone. Just destroy it with all my hate for it. **** this ****ing piece of **** to hell. There is no hope, and **** my life. Whatever.
Be patient. I'll give you link soon but give me answers for this questions.
What was yours last valid ROM ?
Dude you can't flash any recovery you want.... It's not simply working between different ROMs.
Second question. Do you unplaged usb cable before flashing ROM by force update (3 buttons) ?
PS
I am not sure but battery isn't charging even fastboot mode or if totally device is off ?

My last valid ROM is the only one I ever had - EMUI, whichever was the latest about a year ago.
After flashing recovery in fastboot mode, I unplugged the cable and pressed the power button and helt it until it turned off. Waited for a minute to see if it doesn't turn on, to make sure it's completely off - just what the instructions say. Then I tried the force update with 3 buttons, cable unplugged. With stock ROM it was still bootlooping, no changes at all, but with TWRP 2.8.1.0 it got stuck at Huawei logo - but no bootloop. Just Huawei logo, nothing else.
Battery is not charging in fastboot mode because that's how it is on all phones. But it's also not charging when it's totally off, because when I plug it in the charger, it automatically tries to turn on, and starts bootlooping. It's impossible to charge it then. However, with the .bat script I guess I have solved the charging problem - at least the red LED doesn't light/flash anymore.
Emui 3.0 beta release was at the end of 2014, official B609 in January 2015. It's important what rom you have been on. Trying different ones is just a waste of time..
You may try to extract and flash Bxxx part for part (depends on what rom you were) and then TWRP 2.8.1.0/2.8.7.0.I have no other idea, unfortunately.
It's a stupid question, but did you, when trying to boot into recovery, press volume+ for a longer time?

Than you probably have EMUI 2.3 ROM version.
Try flashing B135 recovery from here.
Next try to install B135 ROM from this link.

No, it broke down before EMUI 3 came out, then. I guess I had the ROM which was just before EMUI 3.
Usually when trying to boot into recovery I press the volume+, hold it for about 10 seconds, and then press and hold the power button until it starts turning on. Then I hold both of them for some time, then release the power button but keep the volume button pressed. I've tried doing it differently - holding both buttons for longer time, releasing both as soon as it starts turning on, nothing I've tried works.

B135 recovery
http://forum.xda-developers.com/ascend-p7/general/trying-to-update-rom-1-2-t3222485
I uploaded it couple days ago...
OK, I left it "charging" for 2 days straight, hoping maybe battery was too low to flash partitions or whatever. Just wanted to make sure the battery is charged enough. I can't check the voltage or the percentage, because "fastboot getvar battery-voltage" always says that it's forbidden, no permissions, whatever.
So, I left it to charge for 2 days, and now I tested all the things you guys have posted here. Carefully, one by one. Every fastboot flash command returned success, but in the end nothing changed. Doesn't matter which recovery and/or boot I flash, it's just stupidly bootlooping all the time. Nada.
Finally, you can buy a defect P7 (with a broken screen or anything like this) for pretty low money on eBay and change the motherboard.
But I could also understand it well if you just throw it out of the window.. You had really bad luck.
Probably i have the same problem..... You solve yours problem with this ?
Nop, didn't solve the bootloop. I managed to get a donor phone for 55eur though, which had a bent body and wasn't functioning well because of that, and the screen was a bit cracked too. So I did a motherboard swap. Worked perfectly, but the battery connector protecting case screw doesn't hold in anymore, so sometimes it just turns off because it loses connection, or something. I tried to fasten it with some duct tape, hoped it'd help, and put a hard case on it - got better, but still fails sometimes.
I try give it back on warranty, i hope thei repair it.
I am in the EXACT same boat as edzjins. I have wasted 4 days of my precocious life trying to flash stuff on a phone with a completely dead battery.
I just doesn't work, period!
The only possible fix is to buy a new battery, replace the old one, and after the new battery is installed, have all of the flashing software ready to go and fired up before the new battery dies, too!
Its a time game.
Just like edzjins, there was a brief period of time when I thought I could stop the bootloop via TWRP recovery, but was unable to and the battery completely died.
Be wary of trying to flash "EdXposed" framework with TWRP. Instead, flash it only through Magisk.

SOLVED! (Hard)Bricked Xperia T

Warning: LONG POST incoming ***
So I think I'm having the worst brick I've ever encountered on this phone, had tons of softbricks before and I could almost always sort them out easily, this one I'm having right now unforetunately is not the same case.
Current situation, phone won't boot up, no logo, no nothing, pressing power on button gives two RED blinks, holding power on gives continuous red led blink, now, vol. Up + power wont work anymore, same as hard reset of vol up+pwr with 3vibrates, it does work a few days ago but not anymore (I'm thinking about the issue of hard reset that results in about 50+ hrs or battery draining and recovery but not so sure if thats the case right now).
I've tried going flashmode but it just wont remain in flashmode, I can enter on flashmode briefly, proceed to flash stock ftf then somewhre along the process, (system.sin i think) phone exits flashmode then red led will show up. Fastboot wont work either.
Last observation i have is during wall charging, initially, when I connect to charger, no led light will show for about 3sec, then GREEN led will show and blink around 5times in about 1min, led disappears for a few sec then straight RED led will show for about 2min, and the cycle goes on and on, been monitoring like this for about 3hrs now, will continue until tomorrow.
Note: worst case, I think battery is flat dead thats why it wont charge, or something got fried during usage, never flashed antything for a few months, last thing I remember is I'm having a series of reboots, during long hours of mobile hotspot. Also worth mentioning, this phone auto reboots when it overheats during charging.
This may be a long shot but if anyone miraculously knows a workaround here other than getting a new one, then that'd be a huge help.
That's all, Thanks!
hi
I'm having a similar problem on my Xperia TL (LT30at). It was running on android 4.1.2 and I tried to flash it with a 4.3 ROM (originally built for LT30p, customized for US). During the process, there was an error while the flashtool was processing system.sin. In my case, there's no LED indication, no vibration, no nothing. The phone just won't respond to any button press combo (the battery was about 80% charged).
Plz help.
RESTORED!
Update: After long hours of battling this bricked mode, I've finally restored my phone! Stock FTF won't go through flashmode no matter what I do but luckily "Fastboot Trick" did the work along with numerous Trial and Errors, basically I was able to access fastboot by following and READING all of the instructions on xperia recovery pages here on XDA, from charging cycles, battery disconnect via opening the phone, flashmode/fastboot access, rubber band trick and so on.
Tried flashing kernel.sin from stock FTF (got into boot logo/bootloops with this), system.sin (can't fastboot flash due to huge file size), and lastly using my current roms (CM12.1 by neo) boot.img and flashing it via flashtool fastboot.this one did the trick allowing me to use my previous kernel along with my still un-wiped ROM data resulting to booting into it's previous working state.

[GUIDE] Recover 2012 and newer XPERIAs from SOFT-brick
The Key is as long as you're getting a response(if you don't get any, wall charge your phone for 4 ~ 24 hours and see if you can get a red led which then means you can still save your phone), vibrate, led blink, then you can bet you can still recover your phone. You just have to try everything you haven't tried before. That's all!
I had my T also similarly "bricked" last summer. Flashing always resulted in errors. Rubber band while powering helped, but only worked with original Sony charger. No luck with a Samsung one. After several reboots flashing went ok. The phone was stable only with battery almost full. After I replaced the battery, everything works well again. I guess the battery has been damaged by different chargers - a Samsung 2A (for tablet), in-car, and external battery pack. Currently evaluating CM 12.1

Good thing replacing battery works for you, though I have recovered my phone, I think mines hotspot module got damaged already due to extensive usage and overheating from before (currently experiencing random reboots right now when data is on), gonna check to see if this is kernel or hardware related.
PS: WhiteNeo's NeoWave(KK) and CM12.1 ROM's(development stopped / best version though is 20151010 afaik) are the fastest I have tested yet. You should check them both .
Xperia TL (LT30at) Hard Bricked!!
Well, it’s pretty much obvious that I have hard bricked my phone.
I’ve been searching over the internet (especially on XDA) about this issue and I’ve realized that I’ve caused my phone’s bootloader to be damaged and that’s why it won’t boot at all. Before unlocking the bootloader, I did not make a TA backup (as I’ve seen in some posts that it is required to restore security units in case of boot failure) and now I don’t know how to fix my phone. Most likely, I need a suitable firmware for my phone to flash it with and hence to restore bootloader, but I haven’t found a firmware for my phone anywhere over the internet.
By the way, my phone is recognized as ZEUS flash device when I connect it to my pc, so I feel like there is a chance to recover it from this brick. I took it to a repair center, they tried JTAG but the guy said it didn’t work. The phone takes the dump but still doesn’t boot.
Could anyone help please?

Not that sure when it comes to bootloader errors but I'll try to help, if it's detected on your PC, then you might still be able to recover it (mine is not even detected on my PC the last time it got bricked, but I got it fixed(detected) with proper driver installation: [Drivers] FlashTool Xperia Driver Pack (v1.5) [20140318] by @DooMLoRD), check troubleshooting section if you are using Windows 8 as you might encounter driver signature error during installation .
Question: Does it respond to any action? eg, vibrate, pressing power button just once(if it blinks red LED twice = phone is still alive), soft reset & hard reset, wall charging, fastboot or flashmode when connected to PC?

No. It doesn't vibrate, no LED blink, no fastboot or flashmode. The phone is non-responsive to every button press. However, red LED blinks just for once when I connect it to my pc and when the battery is unplugged.
So far, I've a pretty sure idea that the phone is in "dead boot" and somehow I've to restore its security units / TA backup, as the boot partition is corrupted. Unfortunately, I don't have a TA backup. However, I could make use of TA backup from another working LT30at.
P.S. I'm using Windows 7 and there are no driver issues. The phone is recognized by my pc as an ZEUS flash device.

Bootloop usually means boot kernel problem, Can you fastboot? try to fastboot flash your previous ROM kernel and check to see if you can boot normally to your previous rom.

You mean red LED blinks during charging? Did you flash anything before this occured? Try first charging it for 2~4hrs, (also check if red LED still flashes during charging after a couple of hours), then try powering it ON... does it boot? If not, try soft reset with your phone (hold vol-up + power button for a few sec), it will vibrate ONCE, that means soft reset, power it ON... does it boot? If not, try hard reset this time (same method as soft-reset, this time hold the buttons longer, you will first get 1 vibrate, just hold it still, then you wil get 3 vibrates = hard reset).. power it ON... does it boot? If not.. try charging it a little longer and repeat the process, see if you can get it to boot that way.

I will tell u my problem in detail I have a Sony Xperia e3 d2212 running stock 4.4.2 I rooted it without unlocking bootloader with" kingoroot" later saw a few privacy issues with kingo super user and used "supersume pro" to get super su as superuser and to get rid of kingosuper user
then tried an boot loader unlock with an app named "ez unlock" then tried flashing cwm
the mistake I did was that I flashed the cwm file which was made for my phone running 4.4.4
and now if it is low on battery the red led blinks only when I hold the power button
if I put it on charge for a few hours and then unplug the charger the red led keeps blinking all day long
let me know if u understood
sorry for the confusion though

[SOLVED]Mi5 completely dead

Hello everyone,
I have-or had- MI5 with latest cm14.1 on it, today I downloaded the latest rom from xiaomi.eu -Nougat-. I rebooted into recovery, wiped partitions, flashed the new rom, flashed successfully, and then flashed a font zip, the installer hanged at unmounting system for a long time, I forced rebooting it through holding power button the phone turned off and then never worked. nothing happens, no led when connecting to charger, pc does not recognize the phone at all, no sounds when connecting it. recovery and bootloader does not open. it is completely DEAD. Any help?
same h ere except i didn't get any errors while flashing except the normal command[log] error for all nougat roms. phone is just dead with no signs of life.

I got this error as well,
After some search it seems using a deep flash cable could, I cannot make one currently so maybe you could take a look and try it
http://forum.xda-developers.com/showpost.php?p=69727277&postcount=2
I just checked the second post in the xiaomi eu thread
"- NEVER wipe /system partition manually in your life!"
hmm, I have always done this
Edit:
Many people reporting the same issue their.
There's another way to go to EDL mode which is this

Do follow the videos, i was hard brick 2 times but now it's working
The issue is, you flashed the CM14.1 on low battery, this then messed up the battery reading, while your device showed somewhere like 50% infact it was around 10%, what need to be done is, do a hard reset with power button a few times while connected to a charger, use a new charger/cable and let it charge for a long time, itll then switch on and charge, leave it to charge till 100% then do a full wipe including internal storage and install a new OS

I don't really think that this is the problem because the "rom" flash completely successfully. I don't think that the font flash would cause all this mess. Anyway, I left it charging overnight and I keep pressing power button with vol +/- but nothing happens. Thanks anyway. it seems I have to either use test points or deep flash cable.
Hard bricked the phone with the same ROM here, tried to solve it with the video's testpoints (making contact between the two dots and plugging the USB).
Fortunately, MiFlash with adb and qualcomm drivers recognized the device. So I flashed many fastboot ROMs (miui 7/8 dev&stable) via MiFlash, but none of them made the device wake up. The only signal of life is the led blinking red when connected to a usb.
Still trying...
EDIT: ok, got it booting now. The red blinking led is actually a good sign, it means low battery. I just let it charge for about 20 min and the led changed to yellow, and then I could boot it up.
It seems like in all that time the phone was plugged into my PC usb port for flashing, it didn't charge the battery. So I think we should take into account what Shaky156 said, just in case.

I just revived my mi5 using the test point method, it is rather simple actually.
Make sure you are using miflashtool beta,
I downloaded this rom china developer
I noticed that even though I chose save user data, I still lost my data.

Good to know it also worked for you, I just didn't believe that my battery was depleted from 70% just by hardbriking it...
After installing TWRP it asks to decrypt data even though I did not encrypt, hmmm what now
Edit:
I just did factory reset in TWRP and now I can see sdcard.

I also had my Mi5 die earlier today. Here's what I did to get it back:
1. Popped-open the back cover, removed the screws from the top panel
2. Disconnected battery (left side)
3. Connected battery back
4. Shorted the two contacts at the right side of the board
5. Plugged original USB in
Note that using a deep flash cable is a less intrusive way of doing steps 1-5, but that's what worked for me.
At this point, the PC detected the phone in EDL mode. I then attempted to flash the fastboot ROM for Mi 5, however, I kept getting errors about Missed Hello / Issue with COM port.
6. Downloaded an up-to-date version of Mi Flash (beta didn't work for me), disable Signature Enforcement (Windows 10) and install Qualcomm drivers
7. Downloaded a MIUI 7.5 fastboot rom
8. Flashed, got an error, about storage being not enough... But the screen turned on with the Mi logo. I was finally able to get the phone into Fastboot.
9. Successfully flashed MIUI 7.5 ROM using Mi Flash.
If you are still getting the COM port issue or Hello, try disconnecting the battery again and repeating steps 3-5.
Good luck.

Thanks for the reply, but I already fixed it this way. I used miflashtool beta since the final release did not work.
The problem is did you lose your data after the flash? because I lost mine even though I checked save data in miflashtool

At that point, I didn't really care if I lost data since I didn't have much on it anyway. Nice to hear that you got yours back. Those were dark hours, yes?
Thanks for giving a hope (checking way to recover from video). I'll get proper screwdrivers soon and try do the same.
I have narrowed down the issue, its the nougat firmware thats caused these recent issues. Xiaomi has distributed an unstable bootloader. I highly recommend reverting back to marshmallow firmware and OS

I can confirm that this 100% works for me. You need to be a bit patient with the tweezers and getting the contact points right. It didn't immediately work for me, and I think I had to try a dozen times at least. But eventually it did recognize it. Once MiFlash can see it, you need to use the latest China stable rom. I tried the latest china dev, but it kept on giving errors of missing hello packets.

Bootloop and nonstop Restart Issue

Helllo,
My Mi A2 can't boot into the system it keeps restarting all the time. Even when I have tried go to fastboot mode, it goes it, but after several seconds it restarts, so I can'd do anything about it.
I have tried power+up, but "no command" error.
What can I do?
Is there any solution?

Open the phone with screwdriver and short the "test point" ...then when in edl flash the stock ROM ....and anyway after that ..in fastboot boot twrp and flash a zip from the global telegram group or my other posts to restore your persist
If after that your phone still fails to work it is a hardware problem causing this ....

Update:
I have replugged all the cables and while battery was drained I have turned it on again.
It worked!
I even make an update for android. But after some period of time, it started restarting and now I have the same loop.
I have unlocked the bootloader while it was working, but it doesn't help me right now at all.
Phone keeps restarting...
While it was working and charghing, some application was automatically opening and sensor started making some clicks.
When I had the same ecounter with other phones, it was battery fault.
What do you think guys?
I am also facing this issue. Sometime it reboots randomly but other times it works fine. Should I roll back to Android Pie?

Hi! I am facing a similar issue: Suddenly my phone shut off. When I wanted to turn it on, it would shut itself off after ~3 seconds of the boot screen. If I plug it to charge, it would start rebooting every 3 seconds.
I have left it charging for a long time, and at a certain point it stops doing this and shows that it is fully charged. I have tried to unplug it and turn it on after this, but I am getting the same result. Once again, charged it, and tried to turn it on while connected. It turned on, but once I unplugged it (before unlocking it) it froze .
Recovery mode does not work (same result), but fastboot works. Unfortunately I can't flash it as I can't risk losing all my data.
Having said this, I want to know more details about what has worked for you. Did you drain the battery and then connected it to charge?

That seems quite cheap. It's up to you, I guess.
If you want to solve it yourself, you can give it a try to flash it in EDL mode. I have tried it with no success yet.

Question Redmi Note 10 Pro stuck in a boot loop

Today I left my phone in a cab and got it back in the evening. But after I got my phone it was stuck in a boot loop (after force restart - power button press and hold - it will go to battery icon and automatically restart after a few minutes and again goes to battery icon). Please see the video to understand the boot loop. Unfortunately, Developer options of the phone were not enabled.
Can boot to recovery but can boot to fastboot.
Can you please help me to boot my phone back to normal or sideload a ROM via adb.
tia
Was able to fix the issue. Followed below steps,
1. Kept phone until the battery fully drains
2. Plugged into the charger and charged the phone up to around 65% while the phone is switched off.
3. Switched on the phone when the cable is disconnected.
4. This time the phone was booted to recovery. No battery logo anymore
5. From recovery, rebooted the phone. But again it was booted to recovery.
6. Wiped all data and rebooted.
7. Phone was booted to MIUI os but had to set up the phone again from the beginning.

I think your battery is empty. Leave it on power for a while and check if its charging. Maybe the charginglevel is too low for booting up.

I hope it was that simple ..it seems probably like a bad update. My gfs phone did the similar today
The digitizer stopped working, I force reset the phone and boom ..recovery mode - Trying everything but it doesn't work. Wipe surely would work but she has pictures and videos so I'm trying to avoid that. Plug it to charging but she remembers it had like 75% of battery ...geez (hoping for a miracle)
EDIT: Probably this happen from the bad xiaomi update, anyway I did wipe the data and as expected it work without an issue, I'll unlock this phone and ditch MIUI (I mean I did it to my phone Xiaomi Mi Mix 2S from day 1 - I hate miui) ..now my gf has a reason to hate it too
A factory reset could be painful, since you would lose everything on the device. I saw a guy tap all over the back of the phone with two fingers, and boom! The Redmi Note 10 Pro boot normally! I tried it on a friend's phone, and it worked.
Hello,I had a kind of a similar thing.
I left my phone to charge and when I was back it seems to be stuck in a boot loop(MIUI14)
Well,I tried to force restart but the same.
Before I go to recovery mode,accidently,I putted the phone in fastboot mode.I restarted it in the try to go to recovery mode but the phone started normally.After boot,it's shows an update compete message,so te problem was from an android security path update whatever.
