Emui 9 Random Shutoff - Huawei P Smart Questions & Answers

So I am on emui 9 and I unlocked my bootloader.
I booted it up and like 20-25 second later it Just shuts off like no shutting message no vibration just the screen going black. Why is this happening only when the bootloader is unlocked. Please help me.

Mi A1 takes a bit more time on Boot logo

When I bought and booted it there was no such lag, but when I tried a failed root with TWRP+SuperSU device bootloop'd
and I had to flash tissot_images_7.10.30_20171030.0000.00_7.1_82ffdfe70c on the device.
so now device is booting but I am noticing that boot logo of Mi is shown for 20sec . Has anyone faced this nuiance ? if yes is there a way out ?
Sounds like standard "pause"/warning due to unlocked bootloader which probably can't be skipped. Once you lock the bootloader, it should boot more quickly. Please keep in mind that you have to have fully stock system before relocking the bootloader.
yes. you can say that.
but only saw the warning once and then I accepted that delay could be due to that. and now even after full flash and lock all script the delay is bothering me. Should I contact mi support or exercise 30 day replacement.
Same here, all started when flashing the first rooted boot-image. But i can clearly remember that after a full flash with relock of the BL, the boot logo was lasting only 5-6 secs.
Now i have reflashed it all (without wiping data) and it is lasting 20 secs anyway

P9 Lite not turning on (Stock system)

Hi all,
I have been using my p9 lite for almost under a year. Last night I factory reseted my handset. After a successful restart and configuring all the initial settings the phone asked for a restart again but afterwards the phone couldn't boot up. Before the final restart the battery level was 55 Percent. Now the battery status shows zero. I left it charging overnight the battery status shows 100 percent but when I try to turn it on the service light blinks red few times and after a slight vibration the phone is unresponsive. Not even Huawei logo shows up after the vibration.
I cant even boot into recovery mode.
My Oem and bootloader is locked as I am on stock system.
I am able to get into fastboot but I think thats not helpful as the bootloader is locked.
The phone is single sim variant : VNS-L21
Updates: So, I went to Huawei Center, the phone is not in warranty anymore. I opened up the phone to try to remove the battery and reconnect and then boot into recovery mode but still no change in the situation.
Please help me out. Thanks

hi, do you dolve your problme? i guess i have the same problem XD
regards
My P10 plus started this exact problem today. Always stock, never rooted or boot unlocked.
I was playing a game and it rebooted. Started again and lasted a minute but then constant bootloop to eRecovery screen.
Did the erecovery image download and didn't do anything brought me back to the same screen
Tried to factory reset on the ecovery screen and then booted, but during setup it rebooted.
Went to fastboot screen (pwr+vol down while attached to usb) and rebooted after. I was able to go through setup.
After letting it for sit for only 2 minutes as I type this message, it randomly started rebooting on its own.....and now back to recovery screen.
FACKKKKKKK
UPDATE: Took my phone in to a cell repair shop after exhausting all my troubleshooting options.
They said they took the phone apart to disconnect the battery and do a full power drain. Then after reconnected they installed EMUI 9.1 again via USB and got the phone up and running.
Been working for me for the past 6 hours, but the phone just rebooted on me once, so i'm sure they're still an unsolved demon in it. but no idea what it is right now.... May be time to start phone shopping.
maybe just battery broken, install app accu battery or any other to check batery

[Nikel] Redmi Note 4 mediatek Red State

I have a redmi note 4 mediatek variant and it's been stuck in bootloop for the past 2 days. It keeps restarting and doesn't go into fastboot mode.
The bootloader is locked. It won't go into recovery or fastboot. Sometimes it turns on when holding the power button but then goes into a bootloop.
This was the message last displayed on the phone:
RED STATE
YOUR DEVICE HAS FAILED VERIFICATION AND MAY NOT WORK PROPERLY
YOUR DEVICE WILL BOOT IN 5 SECONDS
And then it shut down and hasn't responded since.
Going to a service center probably won't help since this is a chinese variant and I live in India.
It was running all stock without root and no part replacements.
hi there. your problem already solve or not? i got same problem same as you yesterday, the solution is you need to install mi unlock on you pc, then unlock bootloader. done.

I had this too. Just soft reboot pressing Vol+ and Power until the device reboot... It will be ok after
Sad moment, same situation here. 2 days after update my op6t suddenly starts showing the boot animation. After I pressing Vol+ and Power the phone reboot.
Nope, no issues here!
Same problem here. T-Mobile Converted phone, 2 SIMs (TMOBILE+Verizon). Had this problem 3 times. So moved back to pie...
Do you have TMobile converted phone ? 2 SIMs?
