You need to flash again the stock rom, the factory reset won't work.
You can found it here http://forum.xda-developers.com/showpost.php?p=51090040&postcount=2 and flashing through fastboot
I don't know what frameworks-res.apk you used, but maybe you forgot set the right permissions, or maybe you took the files for other device.

sorry for the late reply.
In the dell's opensource page there aren't files for the 3730 (i don't know why)
but, may be i'm wrong, there aren't tutorials for flashing in fastboot, i only found posts in xda's dell venue general forum.
i'll write here a guide if you still without founding a tutorial and for any others if found this post
you need:
intel usb drivershttps://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices , read the instruccions if you are in windows 8 (i'm on win7 so i cannot tell you if is the same method or not)
The tools for fastboot (there are in a folder called "google") is a little confused so better download @social-design-concepts miKIT_BATCH HERE (before continue let's say thanks to @social-design-concepts for his useful tool that also works for root ),extract wherever you want in your computer.
the files to flash HEREdownload the package for your device and once donwloaded extract where you want in your computer
NOW FOR FLASH
1.-
Install the intel android usb drivers, if you did this before, skip
2.-
Open the myKIT_BATCH folder and run the "runme.bat" file, then type ACCEPT, after that type 2 and press "enter" (the option 1 is for update the driver, in myKIT_BATCH's post 1 is explained) the font should be red.
3.-
boot into fastboot (press button "power" and button "volume down" at the same time) your tablet's screen will display a blue android with gears inside and below it the "droidboot" text and your device info in your device's top|left screen corner , if yes connect your tablet to pc to recognize it (if is the first time).
4.- Open a command window
after the pc recognizes your tablet unplug and plug again the usb cable, should be faster the recognicion this time.
Then in myKIT_BATCH window press "enter" to refresh, the font will become green and will display your device's info, if is going fine in the window type 4 and press "enter", will appear another window.
IF everything still going fine in the new command window type:
Code:
fastboot devices
will display your device's info
5.- let's start with fastboot
BUT first ENSURE THAT THE BATTERY HAVE A CONSIDERABLE CHARGED LEVEL
Unfortunately i don't know what happens if the tablet power off when flashing and if fastboot will work fine after so check your battery charge first
i need to tell you that the 1-4 steps are the most difficult steps (you should have at this time the rom downloaded and extracted only extract the downloaded package (the .7z file)
after this explained so let's start.
5.1.- WIPING
fastboot have some wipe commands so i will explain the 2 that i used:
Code:
fastboot erase cache
This code explains itself, you can try this code to verify that your device is connected
Code:
fastboot erase data
easy to use but powerful, this will erase app's data and also your internal storage (the 11GB that the tablet have to store files), unfortunately i used this without know and i lost 8GB of files
5.2.- NOW TO FLASH
works almost equal with the wipping commands so it's easy to explain.
let's start with system
for a easy explain you ned to open a window where the rom's files are stored in your pc and in the command shell type "fastboot flash system" and after that drag the system file (system.img.tar.gz) to the command window after dragging the file will appear in the command window the full path of the file
I.E i have a dell venue 8 3830 and i want to flash the jellybean 4.2.2 stock rom so i downloaded the Venue_8_WiFi_JB4.2.2v1.42_FLASHPKG and extract this in F:\VENUE 8 3830\stock rom folder so after type the command and drag and drop the system file in my command window will display this:
Code:
fastboot flash system F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.system.img.gz
after this the command press "enter" and you don't need to do nothing (maybe your window will turn off and maybe you try to turn on but will keep off, don't worry only let fininsh) the fastboot program will start to prepare the file for upload to the tablet and after that to flash.
this will finish in 1-2 minutes.
NOW THE BOOT.IMG
is the same way than system but faster.
after finishing flashing system (when the window diplays the elapsed time) type: "fastboot flash boot" and drag and drop the boot.img file in the command window
I.E. in my device will be like this:
Code:
fastboot flash boot F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.boot.img
press "enter" and will do the same like system prepare,upload and flash the file.
there are in the download package more file but only with BOOT and SYSTEM flashed your tab should boot
but if you want to flash the other images you need to type
for recovery:
Code:
fastboot flash recovery F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.recovery.img
and for fastboot:
Code:
fastboot flash fastboot F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.fastboot.img
for my example, for you will be change a little
thanks to all who read and understand this guide, bad english

unfortunately i don't have a computer with windows 10 so i can't solve easily.
i found this googling, so with a little of faith :fingers-crossed: , is the same error than yours http://android.stackexchange.com/questions/118823/how-to-install-adb-drivers-on-windows-10-opoit's for the OPO, but is about the same "intalling adb driver", so could work
in a dessesperate attempt, you can use the update usb drivers in "myKit_BATCH" typing "1" after typyng "ACCEPT"
I fixed it with 15 seconds installer!, i gng try to fix tablet
But i found next problem, after connect tab to PC, just UNKNOWN, and tab is not showing in mykit

Ahh that's add driver not recognize your tablet, I suppose that you connect in fastboot mode,
Try using the option of update the adb driver in Mykit_BATCH, you don't lose nothing trying.
Other option is trying the dell's method http://opensource.dell.com/releases/Venue_8_3830_CloverTrail_plus/developer-edition/Download the pdf file and read the instructions from page 2 to page 9 if still not working
here is the sdk tools for windows that the pdf wants
I downloaded SDK tools, i installed Google usb driver, because it say not installed, when it was installing it said: Disable adb driver, ineffectual, error code -1, but after install it work good, so i will test with this, when no i will try another way, that u wrote here
Finally, tried method, no work, finally, update ADB no working for me, cuz installation always fail, next one DELL method, working but i found problem, dell wrote update driver via google extra with codes, BUT
My first code: USB\VID_413C&PID_B119&REV_????, ????, i think there is something wrong
My second code: USB\VID_413C&PID_B119, i think this one is alright, but then up
Finally with dell next page i'm in!, but my kit no working, in every command shut down, so i using windows cmd, it working too
Mhm bruh, no i'm in flash system, sending 'system' awesome, but it's more than 2 minutes , when it will work, omg u r awesome
Bruh, yay, i did it, thq u r master <33

Are you telling that the dell method works?
The good new is that your tablet is back (with some problems in the way but work, ). after all now you know how to flash through fastboot. If anyelse goes wrong again, you know what to do
NOTE: Maybe your want to replace the framework-res again, but only will work if is for your device. So i recomend that you modify your stock framework-res by yourself (you can use images or xmls from other sources to your framework-res, this should be safer) using apktool manually or a program (there are some of them in xda, choose your favorite )
Yay 50% of dell method worked, just 50% because Dell have tutorial for setting up ADB service, after it i used your tut, thanks, and believe me i will not test it NEVER again.
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.
Follow steps a) to e) of the opening post.

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!

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,

sorry for replying to such an old post.
could you or anyone else please reupload a 6.x stock rom for the yb1 x90L? i just cant find any working link and am currently stuck with a device without properly working wlan. wlan keeps turning itself off after a few seconds after reboot and only restarting the whole device can turn it back on again... i hope a rollback can solve the issue...

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.

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.

Hi all, i have a problem that i can't solve, is the oem unlocking on my blu life one x2. I downloaded adb and fastboot (windows user), phone and adb drivers, and when i put the phone on bootloader mode, i run the "fastboot oem unlock" command, and the command prompt say: "need user wipe data, do fastboot oem unlock-go", so i put these command, and the oem is not unlocked yet, so I repeat those steps and the command prompt keeps showing me the same message (need user wipe data, do fastboot oem unlock-go). At this point, I have no idea what I'm doing wrong, I made the factory format many times, and I cannot unlock the OEM.
Can help me pls? I want to root my device, but because of this problem, I can not go to other steps :crying: :crying:
Thanks

Hi there, I have THE VERY SAME PROBLEM. Done the same, with same lame results... BOOTLOADER STILL UNLOCKED!!
It is really frustrating... been through many posts and guides but can't finish them... fastboot OEM unlock with the user data eraser switch didn't work out well in any case.
IS THERE ANYBODY OUT THERE WITH A COMPLETE WORKING GUIDE WILLING TO SHARE IT?
Thanks in advance.
J.
I have the same problem also, I have posted on another thread but no responses. here is my error:
"FAILED (remote: Need wipe userdata. Do 'fastboot oem unlock-go')
finished. total time: 0.003s"
Has anyone figured out how to onlock the NEW BOOTLOADER?
I have a new life one x2 that BLU sent me.

I guess no one knows the answer to this problem. This phone used to be rootable but I guess Blu changed something in their latest release of the Life One X2
How to root a Blu life one X2
I actually still use this device and should be able to get you through this.
I'm not sure where are you on the device i.e. partly unlocked ect.
I'll start you from the top and I'll let you pickup wherever you like.
First, let's get our links ready (because I had these ready to go for myself).
I just checked it now, the device specific links still work.
ADB: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
TWRP: https://drive.google.com/file/d/0B6_iuhJQH7aGM0JkOXJkUHdlRHM
MAGISK: https://www.apkmirror.com/apk/topjohnwu/magisk-manager/
STOCK: https://drive.google.com/file/d/0B6_iuhJQH7aGUFdVVkkzUk8yYWs
DRIVER: https://drive.google.com/file/d/0B6_iuhJQH7aGa3Q1cmN3eHI3QUE
DOWNLOAD: https://drive.google.com/file/d/0B6_iuhJQH7aGR05CSnlhWm1HWWc
1) Download The driver, download program, and stock ROM.
2) Install the first two files.
3) Go to: C:\Program Files (x86)\Qualcomm\QPST\bin
4) When your device is off; Hold down the vol up AND down while turning on the device and wait until the text disappears
5) Plug in the phone to the PC and a red light should start blinking
5) Unzip the stock rom (when done, it can take a while).
6) Open QFIL.exe
7) You should see "(COM8)" on the top for the connection
8) Click on the first Browse button and select the mbn file from the extracted stock ROM folder
9) Click on LOAD XML and click rawprogram_unsparse_upgrade and then patch0
10) Click download until the phone reboots into test mode; click reboot to start the 'new' phone
-----------------------------------------------------------------------------------------------------------------------
1) Do the generic phone stuff to unlock the bootloader by enabling dev options and then enable BOTH OEM unlocking AND USB debugging
2) Download and install magisk from the link above and then download the zip file it gives you to flash
3) Download the TWRP image and ADB files listed above and do whatever you need/want to do (boot, flash, or both)
4) Flash the magisk zip file and your done
-----------------------------------------------------------------------------------------------------------------------
Delete the folders fota, fota-updater, and fire from the system partition in TWRP as these are the spyware/adware that BLU added
If you want to disable and other apps that BLU added, you can just rename the file from *.apk to *.ap
I'll try to be around if you have any questions
Thank you for this. I just left on vacation and will not be able to try this till next week, hope you are around then as I am sure I will have questions.

Hello dougo007,
Some of the links are dead and I am stuck and cannot figure out how to get passed the failed error on OEM unlock. It just keeps saying try unlock go.
Could you please provide new links or point me to someplace that I can use to oem unlock my BLU Life ONE X2. I searched and can't seem to find anything.
Having the same issue as you were and the links don't work

Hi pvkid, do you happen to have the files from the link? or new places I can find them I am stuck in the same place you were and can't for the life of me find anything anywhere else that helps.
I will be very detailed so that you are able to fully understand the issue. The issue description, hence, will be exhaustive.
I have a couple of old phones - One a Redmi 2 and the other a Redmi 2 Prime. Here is what I did.
STEP 1: I did not remember if they were unlocked and did not bother to check (first mistake). They remained unused for years. I charged them and tried starting them.
STEP 2: Both phones went to the bootloop. Stock Fastboot and Recovery were accessible. Booted into Fastboot mode as I find it more convenient (and I wanted to flash a full stock ROM anyway)
STEP 3: I downloaded a stock ROM from XIAOMI and flashed each image in fastboot mode. Images flashed are listed below:
boot.img
cache.img
misc.img
persist.img
recovery.img
splash.img
recovery.img
system.img
userdata.img
STEP 4: Satisfied, I did the same for the other phone too.
STEP 5: Rebooted both the phones and found them NOT ONLY not booting, even fastboot and recover did not work (both partitions probably not working).
STEP 6: Previously, the devices were detected as fastboot devices. Now they are not. Only in Device Manager I see a COM3/4 port registered. Also, MiFlash tool shows it as such.
STEP 7: I downloaded the relevant firmware files, set the path and clicked on Flash. I get this error below
imgur dot com/ymo6faO
NOTE: EDL pins are NOT shorted.
Questions
1. What did I do wrong? (Was it that the devices were locked? Should it be a problem since I was burning Stock ROMs anyway?)
2. How do I now flash the stock ROM to the device? MiFlash is failing everytime. Manually running fastboot commands (from command prompt/shell) is no longer possible as fastboot is not enabled anymore.
the phone reboots into recovery (I install the wrong recovery, that's why the bootloop), it does not enter the fastboot and when you enter the recovery it just turns off on the boot screen. I can't get into the system either. The bootloader is unlocked. I tried the SP flash tool and it gave me an error brom. And mtk-client, as I understand it, was fixed on miui 14. because there is also an error there. help me please
Hi, did you manage to solve this problem?
What have you tried with mtk client?
hi, I still haven't solved the problem. In mtkclent, I tried to flash the "boot.img" file through brom mode
If the boot flash was successful but you still cant access fastboot or recovery try reflashing the stock rom using brom mode
Step1: Setting up the files
Download the stock rom for your device (I prefer miuirom website)
Extract the downloaded rom
Check if Mediatek USB VCOM Drivers and UsbDK are installed correctly.
Set up mtkclient (follow official guide)
TIP:
After some research i found out that you can speed up the mtk process by modifying the mtk_daxflash.py file. (Source)
Open the file using notepad and search for this line:
Python:
dsize = min(length, 0x200)
And replace it with this:
Python:
dsize = min(length, 0x2004)
Step2: Fix your device
Open the command prompt in the mtk folder
Run this command WITHOUT your device plugged in:
WARNING! This will erase all data on the device
py -3 mtk wl <extractedrompath>\images\
(py -3 or python depending on the installed python version)
plug in your phone and put it in brom mode. the procedure should start immediately
This will flash all the files inside the images folder in the correct partitions (may take a while)
In the procedure you may see some partitions error but thats normal
When the first command is done run this second command:
py -3 mtk w boot_a "<extractedrompath>images\boot.img"
And this command:
py -3 mtk w boot_b"<extractedrompath>images\boot.img"
This will write the boot image to the boot_a and boot_b partition.
Now if everything succeded you should be able to boot into miui.
If not you should be able at least to boot into fastboot, try following step3
Step3: Flash the rom in fastboot (If required)
In the extracted rom path you should see a .bat and a .sh named flash_all.
Put your phone in fastboot mode and run the bat (Windows) or the sh (macOS/Linux) file.
If everything succeded you should have your phone working again .
Hope that your device will work again!

Please PM me if you want your device to be flashed using authorised Xiaomi Server.
I have the same device and I bricked it a while ago by flashing twrp and booting to recovery
From my understanding edl flashing can only be done with an authorized xiaomi account. I don't have one so I had to pay someone on telegram who had one and who could unbrick it. He used a modified version of SP Flash Tool. Although he struggled a bit he got it fixed the next day after I downgraded to windows 10. If you want to avoid bricking this device I recommend you don't use twrp altogether or be very cautious and only use twrp builds from the official telegram group. Compatibility depends on the kernel and android version. For now aosp-based roms have issues with the gpu anyways. (always under 100% load)
Also there is a mtk bootprotect magisk module which might help. (I don't think it will if you flash wrong twrp tho)
I hope these informations are somewhat useful

The thing is ---- Auth bypass is not yet available for your chipset type MT6895.
We have to wait until we can bypass auth to flash using SP Flash tool.

Hi, sorry I didn't see your post earlier. Can you solve your phone problem with an authorized Xiaomi Server? You can write your telegram or something else by which I can write to you. Thanks for the answer
