Hi guys,
I can not turn on my huawei y625-u21. When i am trying to switch it on, phone freezes on huawei logo (first screen which is shown on start - probably called boot screen). I am not able run also recovery mode (vol+) or update mode (vol+ and vol-), so i am not able to perform update of firmware from sd card. Is there any other way to to perform update (flash) of firmware on device, which is not turned on? I have read something about twrp flash, but if i am not wrong, device should be switched on before this process. I would like to install new firmwere, to check, if phone has hardware or software defect.
to put it into recovery mode, you need to hold volume up button and power button, once the huawei logo appears, release power button but keep holding volume up, after about 30 - 45 seconds, it will boot into recovery mode. i have had this issue over and over and i've had to discover this method myself after trying all methods i found, you can reach me on [email protected] in case you need anything else. if it fails to boot into recovery, just remove the battery for a few seconds and insert then try again. i have this very model of phone too.

Hi
did no work also
I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..
Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142
This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:
Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

Thanks for your help,it sorted out my problem! :good:
I tried flashing the bootloader from here.
Then it went crazy or something, and got stuck on the powered by android logo, however i was still able to boot into download mode the first time by holding power + volume down button
to simulate a battery pull then quickly holding the volume down + home + power again. Then I tried flashing TWRP immediately in an attempt to make it work because i have a flash drive to microUSB adapter that allows me to read flash drives from my phone ( so that I can flash the rom properly ). The last time I was in TWRP there was 0 things in my storage everything was wiped after I flashed TWRP the first time
Now im trying to go back into download mode but it just wont let me after the battery pull.
1.) After simulating the battery pull, I immediately let go when the screen is dark.
2.) I immediately attempt to go into download. It shows the powered by android for a second, then flickers then it's back to the powered by android again.
3.) I think my recovery and download is screwed. Or something is going on
=== EDIT ===
I managed to get into download mode and flash back my stock rom.
I think the phone must have read my Power & Volume Down & Home button as the battery pull because I let go of all buttons completely before doing it.
Steps to get out of bricked hell:
• Hold Power & Volume Down until the phone turns off
• Immediately without letting go of the Power & Volume Down button, press the home button as well.
• If the timing is not correct just retry.
Hi Masters,
Need your advice here.
My p9 lite cannot boot up and only shows your device is booting now screen.
I cannot power off even force power off, and there is no responding whatever key combinations i pushed.
The step taken to this error is I did unlock my p9 lite and tried to flash twrp by following the guide, then I cannot enter fastboot mode and recovery mode after that.
I tried take out the battery and let the phone disconnect with power supply, after i put back the battery, i push the power key it still shows same screen as your device is booting now.
Any idea how to resolve this? I assume some fatal error with the motherboard, but i can say nothing after i unlock the phone.
Your suggestion and advice are much appreciate！ thank you!
I had the same problem,what I did was force power off by holding power button for ,well idk how long but until device booted down,then I held volume down and connected it to pc,so it enters fastboot,but you have to do it fast,as it will reboot once its turned off.Then I tried various twrps,revolution recovery etc,and the only one that worked was meticulus twrp.I know you said you cant force power off,but try holding power key long
Once you hold the power off button, the phone will never power off, instead, the phone will reboot and bring you to the error page "your device is booting now" and stuck there. I tried to push the power up or power down button before i see huawei logo, but it will show me the same page.
Yes,when you hold power off phone will reboot,and you have to be fast with volume down and cable.Pre-plug the cable it computer ,bring it near phone,power off and before it boots plug it in while holding volume-
thank you for your suggestion. I tried many times, no matter how quickly i am, I only able to see the device booting page. I have mentioned one point above, i did take out the battery, and i see the error screen after i put back the battery, so i assume the problem with motherboard.
How many of you did return the faulty and unlocked phone to service centre then get "free" services?
Hi Guys!
I'm new to XDA developers, but I've been following this forum for many years.
I would like to resurrect my old phone, a Samsung Galaxy S4 Value Edition (GT-I9515), witch is most likely bricked.
About one year ago, the device started to randomly reboot, until it no longer powered on (It was NOT rooted or modded).
Recovery also did not work, so I decided to flash the stock firmware with Odin. The flash failed, so i decided to follow a (really stupid ) guide that said that to solve it was necessary to flash a PIT file of the Samsung GT-I9505, so I tried it.
Since then, I'm not able to boot the phone anymore.
What can I do with the phone now? What have I tried? I'll try to be as clear as possible:
Recovery mode:
I can boot into recovery only by pressing VOL UP + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Recovery Mode, 3 different things can happen:
It does not power on
It vibrates, then reboot and freeze in Samsung GT-I9515 logo
It vibrates randomly and then open successfully the stock recovery
Download mode:
I can boot into download only by pressing VOL DOWN + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Download Mode, it seems that the screen freeze at a certain point while loading the recovery mode warning (this warning loads slowly, like a slide from top to bottom). The device rarely fully load the warning, and when it does, when I press the VOL UP key to confirm entering download mode (sometimes it does not respond to VOL UP click for confirmation and i must reboot) Odin is able to find the device but during a flash the Odin log stop at Setup Connection, so the device is not responding.
Normal boot:
Yesterday, after hundreds of attempts, I was able to start the phone normally (I don't know how) , it asked for the initial configuration and language, but when I turned it off, the problem reappeared and I was not able to boot it normally. In most cases, the device freezes in Samsung GT-I9515 logo, it continues to restart or simply does not vibrate or power on.
When charging, I don't see anything such as the charging battery icon or the LED.
I realize that I was wrong to flash that PIT file, but is there anything I can do to make this device work properly?
Thank you in advance for your cooperation.
Noone?
Hi,
I'm not very experienced with those root things and followed a tutorial to do so.
I unlocked the bootloader, had TWRP installed and root. This worked. Now I wanted to remove Root and TWRP and go back to the original state. I couldn't find the stock recovery file, so I installed the P996A04V1.3.0B13_MR2_sd_ssl.zip via TWRP from the SD Card. Till here it worked. I could enter the stock recover and boot the phone.
Then Android wanted to install a security update. I allowed it and this is where the problem started.
The install process stood still on 25% for minutes. I thought it stuck and pressed and hold the power button to reboot that I can wipe the memory. But nothing happened. But the installation Process continued suddenly. I had the feeling that this power key worked like a skip key. So maybe it didn't install a file where it was stuck.
After the installation reached 100% the screen switched to black and nothing worked anymore. I couldn't restart the phone or anything but I think the phone was doing something cause it consumed electricity. When I checked the phone hours later I noticed it was empty.
I can reach the unlocked bootloader now, but none of the selections works. Doing nothing to boot or select Recovery lead to black screen and stuck. Then I have to wait until the battery is empty again. Fastboot, Power Off just restart the phone and I end in the Bootmenu again. I can't even fully charge the phone. As soon as it has enough power to start the Bootmenu appears. So I don't see the display of the charging process.
I don't understand how this could happen. I tried different key combinations when the phone had enough electricty to start. The phone always restarts and end in the bootmenu. Only when I press all three keys it's standing still on the ZTE Logo screen but as soon as I release the keys I end again in the bootmenu.
How can I force another Update?
regards
Let' start with the basic questions:
Do you have proper backup of your data?
Which Android Version did your Axon had before it went unusable?
You could try to reflash TWRP.
Boot your phone into bootmode.
Download a proper TWRP Image on your PC (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Open a cmd shell (press the windows key and type 'cmd' -> press enter)
Navigate to the folder where the TWRP Image is stored ('
Code:
cd C:\Users\[I]YOUR_USER_NAME[/I]\Downloads\
')
Type: '
HTML:
fastboot flash recovery [I]TWRP_IMG_NAME.img[/I]
'
Afterwards you could try to reboot into recovery mode.
I don't have a backup. But there isn't something imortant on the phone that I want to keep. I can do a full reset and reinstall, too.
Android must have been the latest offical availabe what's in the file. Was it Android 8? V1.3.0B13
The fastboot mode doesn't work. The screen turns black and the LED blinks red but only for a moment. Then the phone restarts and I'm in the bootmenu again. Windows doesn't recognize it as device.
Is there a way to force it to do an update from my SDCard without it needed to be connected to a PC?

I don't know of any.
But you could boot into EDL Mode (Press and hold Both Volume button and then press the power button) and flash a Stock EDL rom from the Download Center i have linkd before.
It's not visible for the PC. The only thing I see is the charging screen when its total empty and you can't even boot as. As soon as it has enough power to switch to the normal screen the bootloader appears and when I do nothing the screen turns black and nothing happens. I don't even know if it is charging. The LED is off.
Follow this guide to unbrick it and then use MiFlash and flash an EDL ROM
