Hi.
I've been doing some reading because my father is locked out of his P20 Lite. He never turns the phone off, and since he started using the fingerprint as soon as he discovered it, he forgot the PIN in no time. I could hard reset the phone but of course he needs all the data back.
As far as I have read, I could install TWRP and operate in it to backup the data, but first I need to unlock the bootloader, but any guide I read goes through the system settings enabling developer options and such, wich are not accesible without being logged in the phone, wich is not possible without the PIN.
I'm finding myself between a rock and hard place... What can I do?
Suggestions are really appreciated. Thanks!!

If your phone is running EMUI 9 , try Emergency Backup :
Turn off your phone and connect it to your computer using USB cable. Press and hold the Volume Up and Power Button for 10-15 seconds, until the device restarts and enters the eRecovery mode. Select "Emergency backup" .

That's superb! Thank your very much!
The phone indeed gives the option to do emergency backup but for some reason my dad's computer is unable to comunicate via USB with the phone. I asked my father to go and get an USB memory stick with type C connector and we are going to try that way.
Thanks again!

You're welcome
P.S.: also Memory Card can be use for taking backup. You can select Memory Card/USB Storage.

Hi All,
I've got a Galaxy Nexus which looks like working till the standby screen kicks in and then it turns itself off. The phone is rooted.
Fastboot starts while I press the vol up+down+pwr buttons, but once I release them the phone turns off. The volume down+pwr buttons are doing the same effect. While turned on I can browse the whole system via file manager.
Once I connect to the USB cable (power or computer) it turns off.
The phone is i9250 running currently Android 4.2.2
I've tried to figure out some solution in the posts but I didn't find any relevant info. I need to reset the root access and reinstall the factory image.
THe other problem is when I connect the USB cable the phone turns itself off
I tried to download the OMAP flash file from Legija but the link doesn't work anywhere... If you have any info on that I would really appreciate

have you tried nexus root toolkit (find it on xda)
select the "Back to stock/unroot" option and "bootloop" it will flash your phone back to stock.
and wrong forum by the way

Thanks for your reply.
When I plug in the USB the device turns off. I can't put it to download mode either.
I've just downloaded the OMAP flash files but at this stage I try to figure out how to use it. I've installed the nexus drivers but OMAP does not recognize my phone, so it looks like I stuck for a while.
BTW: I can access the root partition when the phone turned on(normal use), so if anyone knows what should I change or delete in order to enter the download mode I would appreciate it. Thx

wait you can turn your phone on? or what do you mean by "I can access the root partition when the phone turned on(normal use)"?

Yes, I can turn the phone on to normal use however it turns itself off when it is plugged to USB or if it is going to standby.
Since it is rooted, with a file browser I can access the root partition. I can NOT connect USB and I can NOT put it download mode or fastboot mode because the phone turns off straight away. I even can make short phone calls from it.
So I'm just after some info on how to fix the USB connection and put the phone back to original state so I can send it to Samsung for repair
Is USB debugging turned on or off?
try turning it on (if its off) and off (if its on).
i am asuming that it only turns off when you connect your phone to you PC, not to a wall charger right?
Bricked means the device just doesn't work at all. This commonly happens (bricked) when there's a software update and it gets half updated. Therefore, the answer is no, its not bricked, but you do have a serious problem there.

If I recall, there's a tiny hole beside the sdcard slot there. Use a pin or something small enuf and try to press into it until the phone vibrates. That should work

Thank you for responding
I tried yesterday, without success. I stayed 2min but it's still not working.
Try to press "volume down" + "volume up" + power button in this order and hold for 30 seconds. This will reset your phone, so of you have some data it will be deleted!

Try to charge phone for 3 hours and try again without SD card and SIM card. If still not working try to reflash Android ROM with Flashtool. Wipe everything before this. Good luck!

If you use window 10 might be adb drivers are not installed properly and phone can't be reflashed via Flashtool. There is a special procedure for windows 10 for installing of drivers. Check if your drivers are properly installed if you use windows 10 of course. Over internet you can find how to install new drivers on windows 10 if used .
This is only shot on the dark .

Guys I need help ...this morning my phone restarted while charging and got stuck on huawei logo screen. i tried different combinations of Power + Volume up and down buttons but it didnt go to any other screen. then i installed hisuite on my PC and connected to my phone through USB cable, and holding volume down button i got to this screen which says FAST BOOT&RESCUE MODE and further reads "Phone Locked" "FRP Lock" in the end below Android logo.
i want to access my phone contents and get backup as I have important files to recover. Please I need some help with detailed step by step procedure to help me get through without damaging my phone or its content. I am hoping some nice techie can write me the steps needed to be taken considering I am a complete noob.
Try forcing your way into the recovery and clearing cache
Vol up + power without having it plugged in
Just keep it pressed for 1 min + if you have to until you see the recovery
When the phone vibrates and turns on let go of the power button so it won't cycle

hi buddy,
i tried but no luck
Any news? I got one in the same condition. When its in eRecovery and i try to update it shows "can't get update info(or something like that)", it doesn't have factory reset button available, it doesn't have wipe button available. When I put it in fastboot, it shows Phone "Locked" and "FRP Lock".
Wtf do I do with this brick?
Thank you in advance! ( Be aware guys! I was scammed with it on the internet - full box, like new, and it doesn't even get into android)

Hi,
have you tried Emergency Backup?
- Turn off your phone and connect it to your computer using USB cable. Press and hold the Volume Up and Power Button for 15 seconds, until the device restarts and enters the eRecovery mode. Select "Emergency backup" . Works on EMUI 9.1 only!
IMO theres no other way to save your data...

That sucks, I think I got exactly the same problem, have tried all kind of combinations. Only different appearing window is fastboot but that is totally useless as the device doesnt appear on Hisuite either. What happens when the batter totally drains ?

Phone does not turn off, and whatever button you press it just keeps showing Huawei start screen except for volume down and power button combination which opens fast boot window. Do you how to connect the device to laptop while in fastboot mode? We have tried fastboot commands on terminal but didnt get anywhere with file recovery...
so no solution?
U can do it, but u need dissasembly the phone, to make test point, if phone isn't hw damaged yes u can fix it in that way
hi may I ask if you have resolved the problem? Been experiencing the same problem when my huawei p20 lite got stuck on a startup logo screen
same problem with me, phone is stuck on start up logo, not moving anywhere despite using all the tricks, any solutions, anyone have?
Hi, I have same problem. Stuck on HUAWEI logo and power off do restart.
Phone is with last stock FW, FRP and BOOTL. locked. I tried update from SD card, but no succes. All buttons combinations not working except fastboot. But in fastboot, there is no possibility to do something due to locked btldr.
But I have one advantage, I have same phone model with same firmware working. Is there any possibility to recover bad piece?
*bump*
anyone who fixed this ?
My father had for weeks a problem with the phone. It was restarting by itself. Now he can not turn it on. It only shows the logo and then it restarts. He has important images on the phone and he didnt do a backup. The phone doesnt show up on the computer with the usb cabel. I am not living in the same city as he so i can not look at the phone. You think its possible to somehow save the images/data on the phone? I never used a Huawei.

The chances are slim, but the following should be tried:
Press and hold Power + Volume Up for 10 sec, maybe it will be possible to enter Recovery. If so, tap "Wipe cache partition" and "Reboot system now".

Unfortunately, it's impossible because of encrypted internal memory.
Thanks
