[Q] G6-U10: Stuck in fastboot mode

Last night my G6 rebooted itself and now it is stuck in a fastboot loop. It keeps restarting itself when connected to charger or PC. Nothing happens when phone is disconnected from charger/pc. Only message on screen is "Keep pressing power key for 10 seconds to exit fastboot mode" but it doesnt help. Phone was stock and not rooted...

did you try to flash the newest rom ?
By the way .... which G6 do you have ? (L11, u10 etc..)

In the title it says U10, thought that would be enough info
I never flashed/rooted a phone before so I didnt try anything so far...
edit: I tried the suggestion from this post: http://forum.xda-developers.com/showpost.php?p=59545669&postcount=4
1. redownload the rom file from official location. ( http://consumer.huawei.com/kh/suppor...h.htm?id=38361 )
It is the official for g6-l11 (-> dl a version for G^-u10 instead)
2. put the update.app into dload folder on your sd card (unpack from the zip)
3. shut down your phone
4. hold volume+ volume- and power button. When it start to boot release the power button, and hold both the volumes until the instalation starts
5. you will see that firmware flashing begin, wait for the end

It seems to work, I see the green android dude and text "updating from external storage" but the problem is the phone keeps restarting itself so it doesnt continue with the update... I suspect sometings wrong with the battery, short circuit maybe?
edit 2:
After giving up last night i tried the above procedure one more time this morning...and for some reason the installation continued. Phone has been up and running again since 8:30 this morning...

where can i get stock rom that can be flashed via sp flash tool? my huawei ascend g6-u10 is bricked after flashing b330. any solution for this?
my phone is dead but my pc can still recognize it

Help - my honor 8 was block - No access Fastboot Mode or Debugging Mode

Hello,
I downgraded my Honor 8 via Rollback and installed the Rom FRD-L09C432B131.
But my phone is stuck on the blue Android startup screen.
I can not use the Volume +, Volume - or Power buttons.
All I can do is let it turn off by itself when the battery is at 0%.
When I put it on, it turns on by itself. Arrives on a blue screen. Reboot once and then stays eternally on the blue screen while heating up enormously.
I have no access to the Recovery, erecovery or via the computer (by plugging it into a USB port).
Thanks

Once your phone turns off, press power button amd volume up button together. This should take you to recovery. Or you can't access this at all?

I can not turn off my phone. It goes off when the battery is at 0%.
If I put on USB or mains, it recharges and restarts automatically. And I can not stop it ...
When I plug it into a USB port, the Power, Volume + or Volume buttons are ineffective.
And when it's plugged into the PC, it does not show up!
So I do not have access ... except perhaps by a software that would force the connection ... or a manipulation other than Power / Volume ..

When I say reboots, it is a program to display the Android blue screen and hangs on it!

does it say android or honor?
going to dload is kinda tricky sometimes and should be done when connected to wall adapter, not pc
can you keep vol- and power pressed while your phone is connected to pc. keep them pressed even after the phone restarts. dont let go. it might take some time. does it go to fastboot?

Is your phone still covered by the warranty?

He can't even boot to recovery.
Sent from my Honor 8 using XDA Labs

Ohhh, sorry my bad

dats prolly because he has mismatched files for the os he's running. he should deffo check if he can go to fastboot. the fact that he cant go to dload doesnt really mean anything because i cant do it either 40% of the time. its a bit iffy. the fact remains, if it boots to honor logo, means some type of os is up there. if he can go to fastboot he can flash stock recovery/recovery2 and try dload again. without proper recovery combo he wont be able to flash anything anyways and warranty prolly wont cover it since its users fault, esp if he has unlocked warning.

Thank you :laugh:

Similar to me, only way is go into bootloader mode, then charge the phone for awhile, you cant do nothing cuz of 0% battery, flash stock recovery, update via dload or direct wifi recovery.

He can't go to fastboot

if he completely bricked it, he'd be stuck at black screen/android logo, not honor logo. either he's not telling us everything (ran out of juice while upgrading / error while flashing / flashing wrong rom), there is no chance all key partitions got wiped if the process finished successfully. meaning at least he should be able to fastboot cause thats the first thing flashing alongside bootloader. no way any type of system partition is up there, and bl/fb is not, even if they are from a different OS. h8 can be stubborn at times, but keeping the cable in pc and holding vol_down+power for good 20s deffo will force it to at least reboot. thats the only way. if this doesnt work, you should take it to a service center.

I guess it's better if he takes it to the service center

Nothing works. So I have to send it to the service center

Thank you all !

Bricked and Boot Loop

Hi all. Looking for some ideas. I think I have ruined my P6X. Model is BLN-L24 and I did the Chinese HWOTA to EMUI 8.0. I then flashed Open Kirin LOS beta 4 and got Oreo up and running! The microphone and speaker didn't work however, so I decided to roll back to the stock system. So via the Update folder method on the sdcard I rolled back first and then reinstalled the original BLN-L24 firmware available on the Huawei website. The phone kept bootlooping and I could not get into eRecovery to factory reset. I then attempted to install TWRP but since the bootloader was relocked I could not do this...so I recalled the saved unlock code I had for this device and did a Fastboot OEM unlock. Now the device simply bootloops no matter what I try to do! It opens with the Honor splash screen, goes into the device cannot be trusted screen warning vibrates twice and bootloops. I can't get into fastboot, I can't get into the sdcard firmware flash update and I can't get into any recovery. The phone will not stay on long enough to be recognized by the computer as it continuously bootloops. Huawei MT version 8 does not recognize the device as being connected and I am now at a complete loss as to what to try...looking for any advice or secret power up + vol key combo to get the phone into either firmware update to reflash via sd card or get the phone into fastboot mode so I can connect to Huawei MT.

Remove backcover and remove battery connector from board and then keep pressing vol- and connect usb to go to fastboot without connecting battery. And unbrick via multitool.

Thanks I'll try and report back!

Ok I opened the rear and disconnected battery. It still is doing the same activity while I try to put the device into fastboot

No need to

i faced the same problem a while ago. my way to solve it was to completly uncharge the phone (let it on or looping till your battery is dead) and connect it with vol- to your pc. for me this helped and bootloader came up again.

Ok I powered down completely, and then reconnect USB w vol down and the phone did the same behavior. I think the motherboard will need some sort of test point to reset to fastboot. It's past my ability. RIP honor 6x

I bricked my phone very, very hard

Hi there. The phone is Honor 8 Pro. No one can help in the phone specific threads, so my hope is there is someone smarter here
So long story short I tried to relock the bootloader with twrp installed. The result is the phone is in constant bootloop mode. I can't go to bootloader nor to recovery mode. The phone boots, passes the bluish honor logo and gets stuck on some EMUI logo on a black screen. Fastboot mode is not acccesible, the PC can't detect the phone at all. No combination of buttons pressed works. I also tried the dload method to no avail.
I also waited for the battery to fully drain and tried to hold the volume up button while inserting the USB cable. It doesn't work.
Anybody been in this situation before? Any solution or any ideas, guys?

Hi did you already found a solution for this? I'm experiencing the same problem...

Honor View 10 Bricked (in a bootloop) after Official update.

Hi,
I recently tried to install the most recent update (the update was for EMUI 9 I think) on my V10 and it is now stuck in a bootloop. I cannot access recovery mode, when I enter fastboot mode, it says my FRP is locked and my PHONE is locked. I can't flash anything because my bootloader is locked. I have no idea what to do, any help is appreciated although I would rather the solution be free (ie not DC Unlocker or funky Huawei).
I had this once before and I solved it by getting into recovery mode, however, I don't know how I got into recovery mode last time it just happened randomly. I tried Vol up + power button, it does nothing just reboots my phone. I have tried vol up + vol down + power button, the same result.
I don't know what to do anymore.
Thanks in advance.
EDIT:
so I solved my problem, I let the battery die overnight and in the morning I tried plugging it in and booting into recovery mode (vol up + power button) and after trying several times (and unplugging my phone so it would die then plugging it back in to try again) I finally got it into recovery mode. From there I pressed download and recover and I got my phone back. The only problem now is that I can't update my phone through the official process as it just puts my phone back into the bricked state. Hope this helps anyone else who was in this situation.

Since the problem is caused by an official OTA, I recommend to send it to the service center

Yeah, I resorted to this last night and called them up for repairs. They were going to take it in but I now fixed my phone (look at my edit in the original post for info).
Thanks for your help though.

I'm glad that you've found a solution

Same issue but no luck for me.
No repair center because my bootloader is unlocked.
