Hello,
I have a Huwaei P9 Lite (2017) with unlocked bootloader, build number PRA-LX1C432B172. Both recovery partitinons probably got damaged and the phone just hangs in the Error Mode screen (just like in the photo attached). Rebooting and pressing any combination of buttons just causes it to go into that screen. If I discharge the battery completely, it will boot into system, but I forgot the password (stupid me). Now even when I am in the system, I can't use adb reboot fastboot, because USB debugging isn't enabled (ADB doesn't even see the phone), so all I can do is turn it off/reboot it, it then goes into Error Mode screen, then wait for it to discharge and I am at the beginning again.
What I tried so far:
- Pressing volume down (or up or both) and Power when in Error Mode screen -> just reboots into Error Mode again
- When completely off (discharged), pressing vol. down and quickly inserting the cable into the PC -> boots into system
- When completely off (discharged), pressing vol. up or both and power -> goes into Error Mode
- When completely off (discharged), inserting charging cable -> after a while, it boots into system
- When in system, adb reboot fastboot -> no way, can't even see it using adb devices
- Connecting it to HiSuite both in Error Mode and system -> it doesn't see anything
Data in the phone is my main concern. All I really need is one time fastboot access, I can figure the rest out on my own then

Hi,
A few months ago I rooted my device and tried to change the ROM. I don't remember what I did but then I bought a Honor6 so I didn't use the Vibe Z anymore.
Today I wanted to get back to it. I managed to charge it and saw the Lenovo logo when pluging to the charger.
But everytime I try to turn it on I got a blackscreen. As i saw a logo I know the screen is not out.
I read this post : http://forum.xda-developers.com/android/general/lenovo-k910-stuck-logo-screen-t2936630 But it's a bit harder in my case.
abd devices : nothing
fastboot device-info / reboot etc : nothing.
I tried to hold the power button for 10+ seconds but it's like the device is rebooting each time (aka vibrations every seconds)
I sometimes see a red light, or blinking red light, or even blue light.
When trying to shut it down, press +/- and plug it to USB nothing happens.
When trying to connect it to my PC (Linux) I can't get the partitions. I can only get a few ones, 134MB and 67MB, not the 1+GB. In fact I see a Qualcomm MMS storage.
Any help would be appreciated,
Thanks,
Bud
Same problem!
But my phone only vibrating on power on, screen is always off and I can´t see Lenovo logo anymore!?
In fresh xp, or win7, device manager didn´t recognize my phone, no searching, no nothing. I was remove battery and try to do same, connect with VOL- and other solution but still nothing...:crying:
Same for me too.
I plugged my phone to the PC to make a new try. After a few minutes I got a surprise!
Some partitions were mounted. But I still can't boot the phone...

Hello everyone,
I deleted some of the bloatware my Lenovo A850i came with, and after thatit rebooted and got stuck at the logo screen. It animates and all, and then doesn't move forward.
If I press power+volume down, it says meta mode but doesn't really do anything as far as I can tell.
Power+volume up brings up a chinese factory mode where I could wipe the whole thing (which I'd rather avoid). When I first entered this mode while connected to my PC, the PC installed the phone's driver, since then, nothing.
Power+both volumes brings me to an android screen where I could also wipe the phone, or install an update from the phone.
If I simply power up the phone and connect it to the PC, I can see a Lenovo Suite install drive, and the two internal drives my phone has, but they are vague and unopenable. It says that I should inster a disc.
I have tons of pictures on the phone, and tons of contacts that for some reason I saved on the phone itself, bad mistake. So I would like to download the internal data before wiping the thing.
Please help!
Update:
If I take the battery out and connect the phone to the PC, I can hear a quick hardware recognition sound, then immeditely the harware disconnected sound. If I watch the Device Manager, I can see a port appear and disappear.

Bump?
Hey I just played around with the Yoga Book and found the following:
1. turned it on until the error screen (when you unlocked the bootloader,.)occured
2. then pressed 'power' + 'volume down' which renewed the error screen which said this time it will boot the device in 30sec (instead to 5 secs of the first error screen)
3. after the 30 seconds and when the error screen disappeard I just pressed 'power' + 'volume down' 3 times.
4. the device booted in some kind of 'service / manufacturer menu'
without a keyboard it is just partly possible to navigate. you can use 'vol up' & 'vol down' to scroll up and down and 'power' to enter sth. It was not possible to navigate to the back button...
any idea what this is good foor, e.g. options like security boot?
also i was thinking if 'factory reset' would also help after flashing e.g. a wrong recovery. which would make testing some recoveries from e.g. the lenovo yoga 3 pro (which has the same chip set) possible.
adb seems to work in this menu, but I still couldn't dump the recovery partition(which is /dev/block/mmcblk0p4) because it always returns 'permission denied'.

Opened command prompt -> ADB devices
command prompt -> ADB reboot bootloader
Phone goes into black screen + blue led
Moves from "portable devices" to "other devices" and shows up as S1Boot Fastboot
command prompt -> ADB reboot bootloader
fastboot flash recovery recovery.img -> stuck into "waiting for device"
I tried installing drivers via different methods with no luck.
Any help is much appreciated
PD: Can't post links to pics
Disconnect the device and shut it down.
Wait a few seconds.
Press volume up and hold it and connect usb cable.
Flash recovery.
Would be nice if you give a feedback!
Hello!
I got my mom's phone because it got stuck on the boot screen (honor Powered by android). She was out in the cold for a while, and when she tried to use her smartphone, it had shut down. As she tried to restart it, it got stuck on the boot screen. So she gave it to me hoping to at least get some important data back. I fixed some bricked phones in the past, but this one seems impossible to fix.
I got fastboot working, but the recovery doesn't seem to start no matter how I press PWR and Vol+. Also fastboot reboot recovery gets me no further than a reboot to the boot screen. Since the FRP is locked, I can't flash a recovery image.
The fastboot screen suggest to open HiSuite. But on my Mac it does require HDB to be active. However the windows version aknowledges that a device can do something via fastboot.
But my win10 machine is unable to properly recognize the usb device. Installing USB drivers seems not to help, even manual install in the device manager fails with driver signature disabled. Also a registry fix from this website seems not to help. In the end, I can't get fastboot to work in the commandline nor HiSuite.
At this point I'm out of Ideas. As it stands now, the only way to recover the data is by unsoldering the eMMC .
There are ways to unlock the bootloader, but as far as I know, it requires wiping the storage.
I'm not sure what happened to the phone outside, but it's really strange that there is no recovery available.
Does anyone have ideas on how to proceed?
