Xiaomi MI9 SE after reboot in recovery complete dead. - Xiaomi Mi 9 SE Questions & Answers

Hi there,
before I send the mobile to my reseller i want to ask if any of you may have a solution.
Yesterday I tried a normal reboot to recovery. The phone went off and then did not go on again. Nothing happens when i press the power button with or without volume buttons.
Even if I connect the charger, the phone does not show anything. It is completely dead
thanks for help

No signs of life? Try holding the power button for 30 Secs...or pushing the power button multiple times if u managed to boot into fastboot or recovery...your should be sorted

Hi,
I had one mobile which did that after an update (it was a Zuk Z2 pro). Really no sign of life.
I let it a part for like one week and the battery went completely down. I tried to charge it after one week, and the phone turned on magically. I guess the update just broke the theorical level of battery so went it was completely empty everything was ok.
But it seem different for you. I guess I would try long press on the 3 buttons, or at least volume down and power, which can bring you to fastboot mode and you will be able to flash with miflash tool.

@eagle*23*: Any news? Did you revive him?

thanks for your answers, forgot to set notification on replays.
The idea with wating till batterie is down looks good idea but i already sent it back to reseller now because dont what to wait so long without the handy drug
The idea with push the Buttons in different combinations i tried several times but did not work.

It's still on guarantee so it may be your best option.

I have the same problem. can anybody help me? did anyone get solution to the case? My case is identical to yours.

Looks like there are not many solutions yet. You could open the Phone but the Flash with this method seems to be stoped by Xiaomi.
One good thing is that it looks like they dont care if your Phone was unlocked or not

HTC Wildfire blank screen

Hi,
I'm sorry if this has already been answered I just can't find it.
My Wildfire's screen froze a couple of times, then the last time I removed the battery and reinserted it.
When I tried to power back up I got the vibrate but nothing on the screen, so I repeated a couple of times with no luck.
I then tried the Hboot method (Hold vol - and power) and I got the Hboot on, but when I tried to navigate using the volume buttons nothing happened, so removed battery and tried to repeat, I couldn't get back to Hboot. I have only been able to get the Hboot screen that one time.
When I power up, I get 1 vibrate and nothing on screen.
When I hold volume + and power button, I get three vibrates and the green light comes on.
When I hold volume - and power I don't get any vibrates, unless I remove the volume - then the power button but still only one vibrate.
I've tried installing the CyanogenMod but no luck.
Is there anything that can be done to save my Wildfire?
Thanks in advance for any help!
Seems like you're in Qualcomm Diagnostic mode. Though I don't remember the solution, some Googling might help

Any help please
I've tried the method stated on this forum but with no luck.
Does anyone have a suggestion?
Thanks!
--- EDIT ---
So you wrote your question again in the "Wildfire S" (Marvel) Forums - in this case the much more important question would be: what phone are you talking about? A Wildfire (Buzz) or a "Wildfire S" (Marvel). Despite the name those have almost nothing in common - they are totally different devices
--- EDIT ---
I'll answer in this thread although you opened another one in Q&A.
You haven't been too specific with your problem but sometimes it helps to have all the details
So here we go:
a) did the phone work correct (besides the freezes) before you took out the battery?
b) is your WF rooted & s-off?
c) which ROM?
d)
When I hold volume + and power button, I get three vibrates and the green light comes on

does this happen when connected to PC or charger or not
e)
When I hold volume - and power I don't get any vibrates, unless I remove the volume

did you hold both at least 5-10 secs or so?

you mean after your problem occured? How did you do that?
Believe me: the more details you provide the more likely someone might have a solution or at least an idea what's going on
OK, sorry for the lack of info!
My phone is a Wildfire, not a WildfireS.
A: Yes, was working.
B: No, never needed to.
C: Not sure, never kept a record of it. It's one of the first models though if that helps.
D: This happens without USB cord attached. When the USB cord is attached I pull the battery and the green light stays on.
E: Yes, I've tried this for over 10secs before.
F: Yes, after blank screen. I installed on SD card and followed the directions. Bare in mind, I cant set Debug or the charge only setting.
Thanks!

That's what I thought. In this case you won't be able to flash any other ROM - you could just do the usual upgrades by HTC
This doesn't sound to me to be a minor problem (but probably someone else might correct me here) - nevertheless - just to make sure: have you tried to do a hard factory reset following the HTC user guide?
- With the phone turned off, press and hold the VOLUME DOWN button, and then briefly press the POWER button (instead of holding it)
if this boots your phone up:
- Wait for the screen with the three Android images to appear, and then release the VOLUME DOWN button.
- Press VOLUME DOWN to select CLEAR STORAGE, and then press POWER.
- Press VOLUME UP to start the factory reset
(errm and yes: this will delete all your user data, of course...)

Click to collapse
But I assume you have done that anyway - did you try to connect your phone to the PC (HTC drivers installed, of course)?
How about charging - does the phone seem to behave normal - i.e. if you keep it from charging for a few hrs does it show the red LED for charging mode and the green one for being fully charged?
That's pretty much all I could suggest from scratch. - Hopefully someone else with a good idea will step in here :fingers-crossed:
OK, still have the Wildfire with the annoying blank screen.
Does anyone have any suggestions on a fix?
Thanks!

besides the suggestion of the Qualcomm diagnostic mode (no I don't know anything about that): did you try to power up without the sdcard, yet?
Furthermore I slightly remember that you could do a factory reset using a key combination - but I'm not sure about it.
Same goes for a RUU. Are you able to connect to the phone with the PC?
Really just random guessing - hard if no error messages appear...
Yes, tried with the SD card.
Because I can't see the screen I tried it loads of times, all with different combinations.
I can't get any vibrate from volume down + long hold power.
I will only get a vibrate from volume down + short hold power.
What would be ideal if there's a way to use ODIN PC to flash a new ROM, well that's what I think it is, faulty ROM?
Thanks!

really hard to say as there's not a little information what's going on. What if just the screen is dead? have you tried to wait after boot and insert your pin after a while (I mean try to guess where the numbers might be) and call your number?
Why anyone want's to use ODIN on non-samsung?!
ODIN is purely just for SAMSUNG products
If you have warranty.. put it to service centre.. they will fix it
Need hard reset power off your phone press volume DOWN and power. YOU WILL FIX IT EASYLI.

Hey there!
I'm bumping this because I have the same problem and creating a new thread seemed more bad to me.
Anyway, I'll start from the beginning.
I found out my battery was swollen 5 days ago. It's probably because of my charging habits. My battery life have shortened everyday this 5 days. Yesterday morning I wiped my battery stats to get a better battery life. When I was back home my phone's battery has depleted while I was listening to music.
I came to home, plugged my phone to charge and waited 15 mins to get it charged a bit to open. When I tried to open it, it vibrated but the "green htc text on white background" screen didn't come up. The screen wasn't working. I tried what is said before in this tried. Once I got managed to see the bootloader but the volume keys weren't working (as above) After some moments of rage, my brother offered to test the touch, I opened the phone, (as I dont have a PIN) we waited for some minutes and then he called me. I mimiced the answering gestured and boom, I could talk with my brother.
I bought a new screen as I think screen is broken. But it could be because mainboards screen part is damaged (probably because of my faulty battery, voltage wavings etc.) or something completely different.
Please guys help me. I can't buy a new phone atm so I have to fix this

Ouch sounds like a rough one :/ OK so you have no visual, but do have touch and audio? Are you s-off or s-on? You could try to "blind feed" the rom.zip of a ruu to the bootloader to try restore it. But it may well be that your battery has killed the screen. Have you ordered a new battery?

I'm S-OFF. I had it written in my old sig.
I too think that it was the battery that killed the screen. Ordered both a screen and a battery but they won't be coming before 20 days at least. Damn you China, why you have to be that far.
Anyhoo, I can't get to the bootloader anymore. Or I think I can't get it. I once managed to get it but volume buttons weren't working. After that in every try I couln't see the bootloader screen. But you're right. When I can't see the bootloader, it doesn't mean I don't get the screen. I could do it with a fellow's help. But only after a few days. I'm getting a surgery in 10 hours. Can't really care about my phone right now

First I have to ask, do you get a vibration feedback when you are getting into bootloader by VolDown + Power buttons?

Desire HD won't turn on

Hi guys,
yesterday I tried to recover the original ROM for Desire HD. During the process in bootloader, my phone shutdown, and I can't turn it on now, even the bootloader wont run. I think my battery was too low, even tought the phone showed 99% (it happened before, even though the battery was almost dead), and it died during the update. Basically, I'm not able to access any feature right now, I'm not sure, if the phone is charging - when I plug it in, the orange light turns on, but when I unplug, the light stays on. Bootloader won't start, but when I press both volume buttons and power button, the phone vibrates 3 times, green light turns on, and thats all.
If you need more info, please ask.
Any help is appreciated, thank you.
You were recovering official ROM from the RUU? This should not result in your device being bricked.
Please try removing the battery for about 10 seconds, then press Vol Dn+Power button and a partial bootloader showing RUU failed or a similar error should open.
Then connect your phone to your PC and again run the Official RUU Setup.
Hit "Thanks" if I helped you. Also click "Donate to me" on the left if u wanna give something in return

Hi, thanks, nothing happens when I push down volume down and power buttons, even after removing batteries. I believe something is actually happening ,but nothing shows on the screen, because when I push volume down and power, and then I plug in the power cable, the orange light does not turn on, while when I plug it in without the combination, it does turn on.
I think that was an official Rom, because I've used it before, and my phone was not rooted afterwards - I did this successfully two times before. However, I recovered it from SD card (pd98img zip copied on the ssd).
Maybe you can try it...just try let the charge is plug in...n leave it be for a hour maybe...don't try to turn on the phone..
After a hour you can try unplug the charge...and remove your battery first...then put it in again...then try power on with pressing volume down+power button..just let see if this time the phone can go to bootloader or not..
Hope this can help..

yeah. I thought about that, but I dont have any desire hd battery here, and I don't know how to charge this one without the phone.
I appear to be having similar problems with it not turning on. when i plug in the charger i get no orange light atall.. if i leave it plugged in (usually within 1hr to 2) eventually it will boot to custom recovery and from there i can reboot the phone and will boot to android. but it does not last very long atall usually about 30mins. have reset battery stats from recovery but doesnt seem to help.
from what i can find online its dieing but can anyone advise on if it will be the battery or the phone itself???
i have just spent $30 fixing digitizer and lcd in the past month. if it is needing a new battery i will proberbly do that but if not it can go..
hope this may help with your problem or any other....

Bricked Nexus 7 [Solution?]

Hi folks,
first post but an important one. Important enough to join and hopefully get some answers.
My LTE Nexus 7 (running 5.0.2) bricked last night. It got stuck on the Google screen and I had no way to unlock the bootloader to flash a different version of the OS. SO this morning thinking I had nothing to lose I removed the back panel with the intention of tearing the thing down. Then it hit me. The common theory seems to be that it's the way the bootloader is not mounting the storage. So as the device never completely powers off what would happen if I cut the power manually. Hopefully a hard reset. So I detached the battery cable from the board and left it alone for a few moments. After popping the kettle on I returned, replaced the cable and tried turning on my Nexus. Lo and behold it works!
I have an unbricked device.
Which is great an all, but I have the proper tools and knowhow to delve into the hardware. More importantly though I'm trying to find out why that might have worked.
Any thoughts?
Has anyone else tried this as a solution to unbrick their device? Did it work?
There is a way easier solution, in case you didn´t know before Push the power button for a few seconds ( >5 seconds ) and it will shut down the device, the same way you are used to shut down a PC by holding the power button

But surely that's not the same as disconnecting the battery?
Trev
It´s not the same but once you´re in a "boot loop", you have no chance of eg. entering the recovery. This is why you need a way to shut down the device first.
But in case even this "forced shut down" doesn´t help and you´re out of warranty, maybe it´s not the worst idea to open the device anyway since you´ve got nothing else to lose

Find 7 (Big problem / glad if someone could help)

So hello community !
I have an OPPO Find 7 device, and I love, but happens that I have some problem with it, let me explain it best I can
It turns out that I simply cant Power ON the device, no matter what I try, no matter what combinations of key I am using or so. Let me explain better.
As I was using one day my phone standard it happened the lock/power key doesn't respond every time I press it, and it was so, sometimes the phone reacted to the button some times didn't. One day I had the device, and forgot to charge it, and it went completely off, so I can't even boot it up. Went to an mobile center, where they repair mobiles or so, it is small place, I explained them what is the problem, they told me it is the button power supply or so, and fixed it. That was nice, finally I had my OPPO again. After 2 or 3 weeks, again the same problem with the button didn't responded and I again took it with me and gave it to the person that fixed it the first time. They said the it is kinda complicated or so, I took it to other place to see if they could fixed it, they told me it is the POWER SUPPLY to the POWER/LOCK key. It is a waste this phone to throw it in garbage because one maybe small problem if you ask me .
Hopefully someone will see this and reply to me, I still have the phone just cant power it on.
P.S The battery is fine, the charger is fine, tried every combinations of key (just the power key doesn't seem to reply in any way or it cant get power supply). I have some minor knowledge in phone's I can tear it down but I need help or maybe solutions from you guys. Thanks again !
Still no-one that can help me maybe somehow

Hi, do you still have this issue?
Did you just upgrade your phone before this happen?
Yes I still have this issue, I didn't upgrade my phone before this issue. I don't think it is an software error tho....
Got my phone still sitting in my shale
I was facing similar problem, but in my case I cannot charge the phone, and it turn out to be software problem during upgrade.
I went to oppo service center and they re-flash with the latest ColorOS then my phone back to normal.
I thought if you just upgrade your phone, you might face same issue like what I was. Or maybe you can try to go to oppo service center?
Try this. http://community.oppo.com/en/forum.php?mod=viewthread&tid=23067
If its software related this will fix it. If it doesnt I dont know anymore.

Sorry, didn't realized you replied my comment already. Since you purchased your device from Oppostyle, i would suggest you to do RMA. However, the process is going to take quite a long time.

Sony Xperia Z1 compact - Hard Brick?

Hi,
some weeks, maybe even 2 or 3 months ago, I tried to root my Z1C because I wanted to be able to use tcpdump. I didn't want to use KingRoot because of some warnings I had read about it, so I decided to flash a new image onto the device. I could kick myself for doing this in quite a busy time but I somehow hurried through it.
After that I rebooted the device and it didn't come back. The only thing I saw after booting was the Sony logo which just stayed forever. Even worse, I recognized I wasn't able to turn it off anymore by holding the power key!
Having done that for my job (app developer) and needing a device for testing I bought another phone for about 100 €, and thought of the Sony as a permanent loss. Because there was much stress in my job at that time I didn't immediately try to fix this, but now, after some time has passed, I wonder if I can do anything to resurrect the device. If not, I won't need to bother anymore. The situation right now is unsatisfying, I have it lying around because there might still be hope, on the other hand, I have no clue what to try.
I can only turn it off by draining the battery, which is relatively easy. The screen stays on all the time showing the Sony logo, and the battery drain is high in this mode. I'm not really able to press any buttons on boot because I only have one try at the exact moment the device starts up after leaving it connected to the charger for some time. After that, I have to drain the battery again to reboot it.
This might be a question of the perfect timing, but I'm not sure. For me, the fact that the power button doesn't turn it off sounds like it has been hard bricked by installing a kernel that didn't match. In this case, holding any of the other buttons at boot time won't do anything, too. Unfortunately, I can't remember what thread I followed, so I can't tell for sure if it was a kernel mismatch... Any ideas? Or should I just dump it and forget about it?
Thanks in advance for any advice

In this case, holding any of the other buttons at boot time won't do anything, too. Unfortunately, I can't remember what thread I followed, so I can't tell for sure if it was a kernel mismatch... Any ideas? Or should I just dump it and forget about it?
Thanks in advance for any advice

It used to be that holding vol up and power for 2 or 3 seconds would power off. I'm not sure why, but with certain AOSP toms starting with LP 5.1, you would have to hold the buttons for 8 - 10 seconds, then it would power off, and without the usual 3 vibrations. Try that out. I would be surprised if it was really hard-bricked just from a bad flash. Try fastboot with a custom kernel and recovery IMG, and see if you can get into recovery.

Thank you SO much! I wasn't really able to boot using power and volume up, BUT after your encouraging words and the idea that I might just be using wrong keys, I researched some more and found out about this little red button within the sim card slot! It allowed me to reboot, get into fastboot, install recovery and cyanogenmod afterwards! I'm happy again
