DEAD Xiaomi Redmi 2

Hello, today i shutted off my xiaomi redmi2 and it shutted off normally.
But it doesnt start back again at all, i tried another battery and i tried charging the phone for several hours straight.
Testpoint method does not work and when i connect the phone to windows 10 pc it just keeps dissconnecting and connecting again several partitions (i think it is linux composite device, ive seen it in another snapdragon phones in the past)
Does anyone have any idea how to fix this phone ?
Btw at the time this happend i was on global stable miui, but the phone was previously running ressurection remix with stock kernel.

u have try to boot into fastboot or recovery?
if u boot in both then u can flash stock rom.. and fix this problem....

I assume you have Redmi 2 snapdragon variant since you have flashed global rom. Try to boot into fastboot mode by pressing Vol Down + Power. Download fastboot rom for redmi 2. Link
and minimal adb and fastboot Link
Extract the fastboot rom file with winrar (.tgz) and you will get a folder named "wt88047..........." inside that folder, there will be a subfolder named images. Extract minimal adb and fastboot to the wt88047 folder. It should look like this:
http://postimg.org/image/3r2hg2nhj
Run any .bat and fastboot process will start

Thanks for replies but it is completely hard bricked, i cant access recovery,fastboot and bootloader and the phone is not booting

So if its not going into fastboot then it must be the battery's problem or (the one i faced)DEAD SCREEN...if you feel vibration but no display then its probably just the dead screen.
There's no solution for it at home, u have to visit service centre.
If you have a custom rom installed, then switch back to factory to bring back warranty.
As said before, if it vibrates but no display the phone's still working(just the display is gone). Reboot into fastboot mode by VOL DOWN+POWER or VOL DOWN and insert usb while keeping the button pressed.. then go to the folder where you have extracted fastboot.exe and then SHIFT+RIGHT CLICK> Open Command Window Here...a cmd window opens up the type in:- fastboot devices...
If there's an output then your device is connected.....Later reply to this if that works

Thanks i will try it

@Blazerstriker Thank you very much, the phone went to fastboot and i fixed it

Hi. I have same problem but get no output from c:\adb> fastboot devices. Pressing vol- and power does nothing. With phone connected to Windows 10 pc by USB I get connecting and disconnecting sounds over and over but phone does not show up.

Pull the battery out, put it back in and connect the phone to pc while it is powered off and when you are connecting it hold the vol-
That is the only thing that worked for me

Thanks for the suggestion but phone still doesn't show up on pc and screen is still blank

Fastboot mode - question ?

FASTBOOT: Volume Down + Power
RECOVERY: Volume Up + Power

I know this is in the wrong thread but ....
When I press volume down + power the phone just reboots normally. So what am I doing wrong ?

1. Ensure that you are holding down volume down until it shows you the fastboot screen.
2. If that didn't work connect your phone to your pc and use the adb command
Code:
adb reboot fastboot
or
Code:
fastboot reboot fastboot
whichever one works.
For things like this you could open a new thread just to make sure your problem is being seen. I guarantee you only very few people will actually see this.

The most easiest way of going to fastboot is to hold down volume down button and after 3-4 seconds connect your device to computer via a USB cable. That's it!

O-Yeah, that worked for me, i wonder why volume down+ power is not working anymore. Thanks :good:

The command "adb reboot bootloader" worked for me and I am fastboot screen (green android guy) an at the bottom it is written that my device is unlocked. But when I try to flash TWRP (for P8 lite - found in this forum) it fails with Failed (remote command not allowed) written. Why and what am I doing wrong ? Can anyone help ?

Perform a hard reset.
Press and hold Volume up + volume down + power
When phone glows
Keep pressing volume up + volume down keys
You see stock recovery
Now wipe all data
Reboot
Check your problem got resolved or not if not resolved then go-to next method
Install adb drivers
Connect phone in fastboot mode
Volume up press and hold and connect data cable.
See device manager
Device should be shown as adb bootloader interface in android device
Now flash stock rom using ygdp tool in fastboot mode.
Wait for process done.
Now check your problem.
Sure it will be gone

Instantly reboots after booting into recovery

I installed LineageOS 14.1 but I was having some blue screens so I decided to go back to stock ROM but I had a brainfart and rebooted after wiping everything except microSD, and now I can't boot my phone normaly, nor enter recovery mode or download mode.
What is happening with TWRP recovery mode is that it seems to load properly but then it doesn't give me options or anything it just starts formatting cache or something for like 2 seconds and then just tries to reboot normally, but there's no OS so it just gives me a blue screen(im not at home right now but im panicking, i will upload a video for better understanding in a couple hours).
And with download mode it just stays on the charging screen.
Did I just brick my ****ing phone? Im on the verge of tears, I have been watching videos and reading for the past 2 hours and nothing seems to help

To boot into download mode, you must first turn it off then connect your phone to pc and then long press power up button.
As with the twrp formatting cache or something like that, you must have downloaded a buggy version. For now, if you have a pc nearby try to boot into twrp with adb.

Download mode still isn't working with the computer im trying, are you saying I just have to turn it off, plug it into the pc(charging screen appears), and just hold power button alone until I get to DL mode? Does my computer need a specific driver already installed for this?
And how would I go about giving my phone commands with adb if I can't boot it into anything? Should my pc recognize the device and be able to use adb when it's in the blue "Subsystem Crash" screen, or maybe when in the first 2 screens before booting into recovery where you have to press "Yes" twice, or when? Maybe when it's charging?
Thanks a lot for the help

Yes, you need to turn off your phone and plug the usb cable in your phone while holding volume up button until it goes into download mode( you must connect it to a pc or laptop). Also, you don't need specific drivers for that.
To boot into twrp with adb, you must first boot into os, or boot into twrp with hardware keys, assuming you can't do any of these then your only option is flashing a new kdz via download mode.
Edit: You need adb drivers installed on your pc if you're going to use adb commands on your pc.

OK I have added the fix in guide

Hard brick of Z5C ... can I save it?

Well, I did it this time.
In a valiant attempt to install a custom ROM, I erased every partition using fastboot,
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
fastboot erase cache
Now what I meant to do here was flash a recovery, using
Code:
//fastboot flash recovery TWRP.img
but repeating this so many times over the last 48 hours, I did not do above and instead went quickly right into below,
Code:
fastboot reboot
The system rebooted as I told it to ... right into a black void of nothing. Now their is no 'recovery' image and no 'bootloader' image ... the phone is hard bricked, won't turn on at all, dead. I was so close to getting to the custom ROM! Is there any chance to get it back into recovery mode? or have I learned a $350 lesson?
Edit: Further research indicates it may be possible to force the system into fastboot using a USB jig. Has anyone tried this method?

When you plug it in while holding volume up what happens?

Nothing. LED flashes red every few seconds. The same response if plugging it in without holding volume up. Along these same lines, holding the power button on for a few seconds causes the small vibration haptic feedback to occur as if it is turning on normally ... but nothing happens the phone remains dead. Similarly, holding volume down and the power key causes a small vibration haptic feedback as it was booting into recovery ... but nothing happens the phone remains dead. I haven't seen anything on the screen appear, or the phone turn on it any way, since executing the fastboot sequence previously described.

Whatever you did, you should still be able to enter in flash mode and flash a stock firmware. And by this I mean full stock firmware, not a ROM.

Ok, that would be great. I would be thrilled to get the stock ROM back, at this point getting the phone to turn on at all would be a victory! Would you please describe precisely how to do enter flash mode with the phone in the current state? To reiterate, the phone will not turn on in any way (normally, or volume down + power to boot into recovery). The only life in the device is a slow blinking red LED when it's plugged in, and a quick vibration after holding the power button. The screen has not turned on in any way, or the LED shown any color other than red, since executing the fastboot sequence previously described.

hold power button + volume up and to force shutdown
and then hold volume up (or down, i don't quite remember) while connecting it to a pc (hold the button while connecting the usb cable).
If the led turns green or blue, congrats

The power key has nothing to do in this context. It is used only to boot into recovery or force OFF.
While holding VOL ↑, plug the USB cable to your PC to enter into fastboot mode (blue light)
While holding VOL ↓, plug the USB cable to your PC to enter into flash mode (green light, or maybe nothing)

Nothing. Device still unresponsive as described.

does your PC detect the device ? (new device sound notification)

Ilko said:

No, the PC does not currently detect the device. All drivers are correctly installed as the phone was recognized accurately prior to the described fastboot sequence.

This is weird. I already erased everyting via fastboot too a while ago, and I could still flash it.
Just to be sure.... unplug all other "smart device" before anything (drivers can't handle more than one device at a time when it comes to FB or flash mode). Open the device manager and let it to the foreground. While you hold the vol down key, plug it and keep holding it until the device is detected. Don't expect any reaction on phone's screen, it remains OFF in both fastboot and flash mode. So, if the device manager reacts, you win.

I'm getting something here which is very encouraging! Executing your sequence causes the device manager to blink (refresh) as if it sees something, however no new devices are recognized in the tree. The phone LED goes to a solid green, reminiscent of a fully charged battery, stays on for about 30 seconds, briefly blinks red and then back to green, etc. The device manager is certainly reacting here it just doesn't recognize the device.

So here we are, you win. Because you have the "two", detection and green led. And if this state goes off after a certain time, it is normal. There is a kind of countdown and the device quits that mode if nothing is sent to it. You should be able to flash a firmware now with flashtool software.
Just ensure you have proper drivers installed properly (WinUSB drivers need to turn signature verification OFF before or Windows will block the installation)

Unbelievable! You saved me! I'm back up with the stock ROM and peace of mind to attempt the custom ROM process again. Saved me $350 ... thank you!!

That's great : )
It is almost impossible to hard brick a Xperia. If something goes wrong, remember flashtool ^^
