Lenovo z5 stuck in fastboot mode - Android Q&A, Help & Troubleshooting

Hi everyone,
first of all, I guess there should be a section dedicated to the Z5 to keep the forum clean!
Other than that, I'm really having trouble with my Z5. I can't find a way to move on from fastboot mode! Can't boot to edl, tried to flash recovery but they won't boot and so on...
Do someone has some idea? I can provide every information you need to troubleshoot that!
Thank you in advance,
Lorenzo Benevento.

Hi , inside stock firmware which .img files you have ?

Hello guys,
Could any of you create a brick troubleshooting thread in this model?
I need help with unbricking my Z5. I think I messed up with the recovery partition.
I can't turn it on at all after I press all the button combinations.
I tried the suggestions on the Sahara error that they did on the Lenovo Zuk Z2 with no success.
Does anyone have a workaround for this kind of thing?

I installed from fastboot, Pixel Dust ROM and after that, the phone not starting. When I connect the phone to PC, I have message with Unlocking Bootloader (was unlocked initialy, on old rom) then Lenovo logo and after a black screen.

I read few forums about this error (https://zukfans.eu/community/threads...e-easily.3504/ and https://club.lenovo.com.cn/thread-3021991-1-1.html), I makeed a USB cable for DEEP Flash,I peeled the usb-c cable and touched Green and Black wires, but without success.
I installed a new Lenovo USB driver and with USB cable for DEEP Flash, I put the phone in the 9008 port, and Installed with successful, many ROMs 3.9.075, 3.9.200, 4.0.390 but every time after the first reboot appear message with opened bootloader then Lenovo logo and restarting to infinite.
When the phone is connected to PC I have on the phone a menu with "First Boot Mode" and the phone is accesible from PC:
"C:\Users\user>fastboot devices
bb806aa3 fastboot"
I will apreciate yours help. Thank you!

Don't worry i've already solved with some CHINESE PIROMANCY!!!!!!! Even with effective IMEI restoration (I couldn't restore the 2nd IMEI because I didn't know how to set up this one manually with the method I've used with my lenovo)

Hello,
I have a Lenovo Z5s. I wanted to install new android rom like Pixel Experience
I managed to unlock the bootloader with adb fastboot.
I succeeded in flashing TWRP recovery 3.3.1-0529 for my device.
I've downloaded Pixe Experience GSI rom available here https://forum.xda-developers.com/z5...evelopment/lenovo-z5s-pro-twrp-3-3-1-t3953346
I have copied and pasted the Pixel Experience rom (.img file) on my SD Card.
With TWRP, I have wiped necessary files for a clean install.
I have launched the installation of the rom, installation was complete, the phone has reboot, I show Pixel Experience boot sequence with Google logo. The process asked me a password (Encrypted?) . I decided to reboot the phone.
Now, the phone is blocked with a bootloop in recovery mode. I can't access anymore to TWRP recovery. (Erased?)
To explain clearly the situation: I have the menu showing these options: Restart bootloader > Recovery mode > Power Off > Boot to FFBM > Boot to QMM I> Start
FastBoot Mode
PRODUCT_NAME - sdm710
VARIANT - SDM EMMC
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - ********
SECURE BOOT - yes
DEVICES STATE - unlocked
No Bootloader, no Baseband.
All of the options return the phone back to the same menu.
The situation seems to be critical (phone bricked) and I can't do anything and I don't know what to do. Is there a chance to save my phone?
Your help will be precious to make my phone work.
Thanks in davance . Best regards.

Hey guys i am also in bootloop with unlocked bootloader ,can you please help us to save our phone !!!???

[Q] VIBEZ k910 BRICKED!!! NEED HELP

I have a VIBEZ K910 with locked bootloader after upgrading to version 4.4.2. Now it's bricked. Cannot enter test mode with the combination Volumn - and Power button. I think the droidboot.img is damaged. Cannot enter recovery either. Anybody can help me unbrick the phone? Pls:crying:
Sorry to hear about your bricked phone. I can't help specifically as I don't have a Lenovo, but having a search around XDA there seems to have been some success reported in the following thread:

See this post - http://forum.xda-developers.com/showpost.php?p=52013378&postcount=412
Another post in that thread suggests:
Turn off the phone --> Run minimal ABD and fastboot as admin--> just write the command for recovery install (don't hit enter yet)--> press volume + and volume - button and connect the phone to pc via usb--> now hit enter and voila. Your phone will boot in recovery.

lenovo k910e 4.2.2 bricked after TWRP for 4.4.2 installation
Hi , this is my first time on the site , so forgive me if ive posted this in the wrong place.
I briked my Lenovo k910e running 4.2.2 rom with google apps purchased off Aliexpress.
What i did was run the flashrec.exe file for TWRP , but not until too late did i realise it was for 4.4.2 instead of 4.2.2.
Now i cannot boot the phone , TWRP was successfully installed and operational , but after about 20 reboots TWRP flash screen is stuck on the TeamWin logo and not accessable.
Ive tried mostl sugestions on this site and others without luck.
I can get the phone recognised with fastboot only after these commands ;
cd downloads
cd fastboot
adb devices
and it seems i may be able to push files to my device.
Is there a working link to the k910 OEM rom k910_ss_s_2_040_0109_131226 someone could direct me to.
All the links i have found so far are corrupted. Is there a way of repairing the TWRP recovery i have in the phone now.
Am I correct in assuming I have to install the OEM factory 4.2.2 ROM to wipe TWRP and istal Lenovo recovery ?.
Any help would be so appreciated. Thanks
Solution ( k910 bricked )
Ok here is the solution even if your device ( k910 dual sim ) is completely bricked as was mine.
I was stuck in Lenovo logo with no success in finding right and working drivers ( windows 7 64x ) and i was not able to to get in recovery official ...everything was just - somehow - deleted...
I had locked bootloader **** and was not be able to flash cmw in working mode ****
There was nothing for me that could recover my phone even if the "hard" way with QPST or miflash etc
So....after 3 days....find this solution and hope this will help you because it is soooooooooo easy finally!
Steps:
1) Download lenovo driver ( i think it is useless in fact but ok....just run it you dont have anything more to loose )
https://www.dropbox.com/s/frbpz16udrefoit/LenovoUsbDriver_autorun_1.0.112.exe?dl=0
2a) Download and install Minimal adb
https://www.dropbox.com/s/uvngsu4vz4hvsky/minimal_adb_fastboot_v1.1.3_setup.exe?dl=0
So now you have to use the right recovery image ( this file has to be inside minimal adb folder )....so here it is:
https://www.dropbox.com/s/ge05m1fe8n4qgb1/recovery.img?dl=0
2b)
Download this ROM ( this worked for me - with other i did try i did get an error )
http://www.needrom.com/download/lenovo-k910-vibeui-2-0/
prefer the last updated version ( 1501 )
Put this rom in the same ADB folder and renale zip in VIBE1411.ZIP ( in order to be easier later )
3) Turn off the device open Adb and write : fastboot boot recovery.img ( to have it ready )
4) Push volume + $ volume - at the same time and AFTER connect with usb to your pc - At the time the device will vibrate HIT ENTER in ADB
This will flash the recovery and after 1 minute device will open in a recovery screen with an adb update option ***
SELECT THIS adb update OPTION !
Your device kow it is ready to flash the new rom ! ( you will realize that everything is right from many usb beeps you will hear )
5)In adb console write : adb sideload VIBE1411.ZIP
This will take a little ....after that your device will reboot ! Dont panic if for a few minutes it will stuck in lenovo logo....
IT IS NORMAL AND YOU HAVE TO WAIT!
Hope this will help you.....please feel free to tell me if this worked for you.

Boot into recovery under bricked condition
Today I bricked K910 after reinstalling GMS apk.
The phone hanged at boot logo.
Nothing can be from here.
I decided to take this risk.
I removed the back cover and disconnected the battery terminal.
After that I plugged back the terminal.
Several tries by power button and volume down to get into the recovery mode. All failed.
Each time it hanged at boot logo.
I have to redo the battery terminal unplug sequence again.
This is correct method to get into recovery mode.
Press power button and volume down till the Lenovo logo appears.
Move the power button finger to the position of the " Home " of the touchscreen position.
Hold till the recovery menu appears. Choose factory reset to erase the phone.
There was two lit small icon below. Make your choice.
The phone will be erased by reset.
Reboot after the process.
I solved my phone bricked problem.
Hope the method will solve your problem.
Good day to all K910 users.
my vibe z cannot access the recovery mode (PWR + VLM DOWN), it only vibrate. If turn on only stuck at Logo. Please help .

[Q] Bricked glass please help...

Hi everyone,
Thank you for your time in reading this. I need help with my bricked google glass. Basically I bought a glass not directly from Google 3 weeks ago. Last night I hit factory restore and it shutdown. When it rebooted it just had a white screen displayed. I understand this as the white screen of death after much googling. As I did not get it directly from Google, I do not have support and they will not honor my warranty.
As such I have been trying all sorts of things to restore it to factory and get it to boot up:
I am doing all the activities in OSX.
1. I am able to access fastboot, fastboot devices shows my device serial, however adb devices does not and adb reboot-bootloader cannot find the device.
2. I was able to fastboot oem unlock using ubuntu as there is a known issue running this in osx. All other subsequent activities were done in osx.
3. I was able to download the factory image from the google developer site. I downloaded XE18.11 and XE18.1 as I remember the device updated to XE18.1 OTA.
4. I put the device into recovery mode by holding the picture button, pressing the power button and continue holding the picture button for 10-15 seconds.
5. When in fastboot/recovery mode, fastboot devices works, fastboot reboot-bootloader works but adb reboot-bootloader does not - it does not find the device, neither does adb devices.
6. I can fastboot flash boot boot.img but the next step hangs when I execute fastboot flash system system.img. It just hangs and does nothing. Manually triggering fastboot flash recovery recovery.img works, it's just the system.img that hangs...
However, if I fastboot -w flashall, it is able to send and write the boot, system and recovery images to the device but it still boots to a white screen after. I was expecting it to work and be restored to factory as the image files were successfully written.
The factory image for XE18.11 and XE18.1 contain the files below:
android-info.txt
boot.img
bootloader.img
fpga.img
recovery.img
system.img
userdata.img
xloader.img
7. fastboot flashall only flashes boot, system and recovery. Do I need to manually flash bootloader.img? What is the danger of doing this? I am afraid of touching the bootloader as this is the only thing letting me connect to the device.
8. What about the other image files like xloader.img, userdata.img, fpga.img...do I need to manually flash those as well?
I would appreciate any help from you experts to help me bring this back to life. I can't afford to have a very expensive brick. :crying:
If anyone can help me fix this, I am willing to donate to a charity of your choice whatever I can afford.
I am desperate and willing to try anything...
Thank you everyone!
Apologies to the mods, if this should be in the glass forum, I did not find any technical/help section there so I decided to post it here.
Alex
Any experts out there who can help me please?

Thoght that i am missing one important step after flashing those miui eu rom. Reboot to fastboot prior the phone reboot into system and unlock the bootloader.

Yoga Book YB1-X90F (Android) - How to Flash back to Stock Rom 6.0.1 /downgrade

hello all
i spent last few hours looking for solution to how to flash Stock Rom to my YB1-X90F and i found steps here and there and finally i got it. so i gathered all the steps in one thread to help whoever want to flush back to stock or downgrade from newer version for any reason.
This will erase all user data.
1. do it on your own risk, I'm not responsible for any damage to your devise.
2. Unlco your bootloader here is the steps by earthCallingAngela ----->>> Here
3. if you having issue to connect your drive to your computer while on bootloader you can install Intel driver, its worked for me, ----> Here
4. now install Intel Phone Flash Tool, i think it will install drivers as well, download it from here
5. Download Yoga book YB1-X90F Stock Rom Uploaded by Flippy498 from here
6. open Intel Phone Flash Tool and boot your phone on bootloader by Vol Up + Power, you should see the tool detect your Tablet.
7. on intel tool click on brows and located the Rom, wait for the tool to unzip it,
8. do not change anything just click on Flush and wait for it, on the middle of the process the tablet will ask you if its ok to wipe user data choose yes
after that the tablet will reboot and finish the installations and power off itself, power it on and wait for it, its will take long time for first boot so do not power it off.
Halo keyboard will not work until you do these steps By vimalbhimani on here
a) Open ‘’contacts’’ app, create a new local contact ” test”
b) Click search button at contact
c) Input ####6020# code into search bar
d) a list of country codes will po up, browser the country code list, then chose country code US and click OK
e) Then device will reboot and update, you should be able to use halo Keyboard after that.
note: i have issue with TouchPl keep stopping, had to chose google instead of Lenovo to get it to work without error
if you want to update the system to latest version (7.0.1) you can just go to update and update it.
if you have something to add please do
Thank you all.
Here's an alternative method for those who don't trust flashing tools due to bad experiences and prefer flashing files manually via Fastboot (like me):
Follow steps 1. to 3. and 5. of the opening post.
Unzip the stock rom (archive) into your ADB/Fastboot folder.
Boot the tablet to the bootloader (c.f. step 6. of the opening post).
Use the following commands:
Code:
fastboot flash gpt gpt.bin
fastboot erase misc
fastboot erase persistent
fastboot erase frp
fastboot erase metadata
fastboot format config
fastboot format country
fastboot format cache
fastboot format data
fastboot format factory
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash config config.img
fastboot flash country country.img
fastboot flash system system.img
fastboot flash bootloader bootloader
fastboot flash oemvars bootloader_policy-oemvars.txt
fastboot flashing lock
fastboot continue
Execute each of them with Enter and wait till a command got executed completely before you try to use the next one.
It might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.

hello all
i spent last few hours looking for solution to how to flash Stock Rom to my YB1-X90F and i found steps here and there and finally i got it. so i gathered all the steps in one thread to help whoever want to flush back to stock or downgrade from newer version for any reason.
This will erase all user data.
1. do it on your own risk, I'm not responsible for any damage to your devise.
2. Unlco your bootloader here is the steps by earthCallingAngela ----->>> Here
3. if you having issue to connect your drive to your computer while on bootloader you can install Intel driver, its worked for me, ----> Here
4. now install Intel Phone Flash Tool, i think it will install drivers as well, download it from here
5. Download Yoga book YB1-X90F Stock Rom Uploaded by Flippy498 from here
6. open Intel Phone Flash Tool and boot your phone on bootloader by Vol Up + Power, you should see the tool detect your Tablet.
7. on intel tool click on brows and located the Rom, wait for the tool to unzip it,
8. do not change anything just click on Flush and wait for it, on the middle of the process the tablet will ask you if its ok to wipe user data choose yes
after that the tablet will reboot and finish the installations and power off itself, power it on and wait for it, its will take long time for first boot so do not power it off.
Halo keyboard will not work until you do these steps By vimalbhimani on here
a) Open ‘’contacts’’ app, create a new local contact ” test”
b) Click search button at contact
c) Input ####6020# code into search bar
d) a list of country codes will po up, browser the country code list, then chose country code US and click OK
e) Then device will reboot and update, you should be able to use halo Keyboard after that.
note: i have issue with TouchPl keep stopping, had to chose google instead of Lenovo to get it to work without error
if you want to update the system to latest version (7.0.1) you can just go to update and update it.
if you have something to add please do
Thank you all.

I followed all of the steps and it says "Flash Failed (Fastboot) PLEASE HELP
Edit: I fixed the problem by simply rebooting it. I didn't think it would be that easy.
SameSame, but L-Version ... cannot find Stock ROM ...
Hi there,
I would like to downgrade 2 Tablets YB1-X90L (not F), this thread is onderful BUT I cannot find the STOCK ROM version for the L-Model (the one with LTE) ... can someone point me out as where to get it ? The background is that Nougat screwes up the playstore ... as discussed in many other threads and there is no -permanent- solution... Thank you!

found myself in the same boat and eventually came across this:

hopefully it sticks around long enough for others to grab.
note that the steps are slightly different in that you have to manually select the .json in the extracted folder.
Could someone please help me with downgrading my YB1-X90L, it just refuses to boot at all after my nephews messed with it, I found the stock rom but I can't get some of the needed programs and drivers,

Here's an alternative method for those who don't trust flashing tools due to bad experiences and prefer flashing files manually via Fastboot (like me):
Follow steps 1. to 3. and 5. of the opening post.
Unzip the stock rom (archive) into your ADB/Fastboot folder.
Boot the tablet to the bootloader (c.f. step 6. of the opening post).
Use the following commands:
Code:
fastboot flash gpt gpt.bin
fastboot erase misc
fastboot erase persistent
fastboot erase frp
fastboot erase metadata
fastboot format config
fastboot format country
fastboot format cache
fastboot format data
fastboot format factory
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash config config.img
fastboot flash country country.img
fastboot flash system system.img
fastboot flash bootloader bootloader
fastboot flash oemvars bootloader_policy-oemvars.txt
fastboot flashing lock
fastboot continue
Execute each of them with Enter and wait till a command got executed completely before you try to use the next one.
It might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.
Follow steps a) to e) of the opening post.

looks like the original link is down, so i searched for the file name YB1-X90L_USR_S110085_1710170829_WW08_EP_ROW_otafull.zip and this came up:
YB1-X90L_USR_S110085_1710170829_WW08_EP_ROW_otafull.zip | Easy Firmware
easy-firmware.com
ive no idea if this is working or safe to use but its a start.
good luck
So my Android YB1-X90F was locking up when trying to boot, just stuck showing the Lenovo logo. Thinking I'm clever I stubbled across the boot menu if you start the device with the Volume Up held. From there I tried the Recovery Mode and did a Factory Reset. Then the tablet started up and shows the Green Andriod Bin Man, saysi Encrypting and promptly reboots. So one starts Googling and ends up here. Some very help information, thanks for that.
So I've got as far as installing all the drivers/Intel Phone tool/Android Suite etc. but I'm still stuck. The flash is locked. Is there another way to unlock this as I can't get into Android to allow the developer options as suggested in Step 2 of the opening post?
Trying the fastbook commands in post 2 also fail
Code:
FAILED (remote: Prohibited command in locked state.)
finished. total time: 0.170s
TIA
LOL @ me, of course the manual fastboot commands fail as that's precisely what the Phone Tool App trying when doing its magic.

I'm in the same boat. I acquired a YB1-X90F but all it does is show the orange Lenovo splash screen, then a black screen.
So here I am reading threads. But I'm already at my first hurdle...since I can't boot into the OS and go into Developer Options to start the boot loader unlock process.

Help needed, stuck at Fastboot Mode

Hello guys!
I've been looking for a solution to this problem, I have a Moto One XT1941-5 that was never rooted nor bootloader unlocked. I left it charging and after about one hour it was at Fastboot Mode, it says that it failed booting from normal mode. Even if I try to restart or start normally, it gets back to Fastboot.
What have I done until now?
- Tried to flash the whole latest STOCK ROM again (manually with fastboot tools)
- Tried with a ROM from another region (mine is OPENMX and tried with RETLA) and I get the same
- Tried with Repair Assistant from Motorola, nothing happens.
- Tried to unlock bootloader, it asks me to enable OEM unlock on Developer settings (I can't, phone doesn't power up)
* Something that gets me confused is about the slots, $fastboot getvar all reports that none of the slots are bootable, every time I flash the ROM it says that slot A is bootable and B not, or that A is not bootable and B yes, or none of the slots are bootable.
Here are some screenshots about the info I have.
You can follow these steps from https://forum.xda-developers.com/motorola-one/how-to/unroot-ota-wipe-data-tested-t3905745 and then fastboot erase userdata and try to boot again.

On June 2018, warranty is not valid any longer. Carrier just give us 1 year here in Mexico.
I never had a problem like this, I was looking forward to find the blankflash for this model but it doesn't exist yet, maybe all I can do is wait for it or hard brick it. :crying:

No, I think this problem has to do with the EMMC memory.

That's correct, now my device shows nothing on screen, it is just black but when I plug the usb cable, fastboot detects it as fastboot mode, all commands are working but nothing else works.
I'm giving up now.

UPDATE:
- I finally found a blankflash (my phone still the same) but you can give it a try.
LINK (copy and paste om your browser) drive.google.com/file/d/1-Dgj4WlbitUUHgcZmuBVR_bSendXLdAx/edit
1. To make your phone go to Qualcomm 9008 all you have to do is download an Android 8.1 stock rom from any region, flash it all using fastboot. You may get an error trying to flash boot.img but keep flashing the files.
2. Once you finish flashing and type: "fastboot reboot", your phone will boot into Qualcomm mode, it should be listed in Device Manager.
3. DISABLE any antivirus and download this blankflash, just unzip it and execute the blankflash.bat file.
4. Your phone should boot up in fastboot mode and you can start flashing the latest stock rom.

Indeed, after flashing an Android 8 firmware my phone went into Qualcomm 908 EDL mode. After blankflashing and flashing the latest firmware had the same issue with "No bootable A/B slot". The same state before hardbricking the phone (AP Fastboot flash mode secure).

That didn't help either, there's nothing else we can do than replacing the main board.
Hello.
I have a similar problem. I have tried all of the methods listed, unfortunately nothing works. I ended up replacing the motherboard. The old PCB is waiting, maybe someday it can be repaired.
