Are you putting the tablet into EDL mode before trying to flash Stock ?

EDL mode is Qualcomm's Emergency Download Mode and allows a force flash software onto the device.

If not and you don't know how to do it, then Google is your friend, there are a few methods to enable EDL mode.

Just fllashed my Tab 4 10 plus X704F

As title says.
I have the tab and the speaker and use them as a smart device. I had it set up so that the screensaver came on but I would still be able to say Hey google and the display would come on and google assistant would answer my question.
Since flashing to LineageOS saying Hey google doesn't wake the screen up so the assistant isn't activated either(this is when the tab is connected to the Lenovo speaker)
If I remove the tab from it's speaker and say hey google it works ok. Every thing else seems to be working as it should, very nice clean ROM.



Does any one have any thoughts on this


Have just found out that bluetooth doesn't work at all now.

Code:
/*
 * I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...). 
 * Please do some research if you have any concerns about features included in the products you find here before flashing it! 
 * YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you. 
 * Your warranty will be void if you tamper with any part of your device / software.
 * Same statement for XDA.
 */

LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.


What works:
Wifi
Bluetooth
Audio
LED
USB
RIL
Encryption
Fingerprint
Camera
Hall sensor
DT2W
Selinux Enforcing

Broken
nothing

device-common: https://github.com/lenovo-devs/android_device_lenovo_tb-common
kernel: https://github.com/lenovo-devs/android_kernel_lenovo_msm8953
vendor: https://github.com/lenovo-devs/proprietary_vendor_lenovo

Important
If you are using this ROM first time, wipe data. Wipe data completely. I mean the option where you need to enter "yes". Use this option and then flash the rom.
This ROM only works with the TWRP I added.

If you want to use GAPPS, flash it directly after flashing ROM. Don't let the ROM boot. Otherwise your device will not get certification, so you will not have Google Access.


Instructions (thx @matshias, just changed few lines to get ROM flashing working)

  1. Put your ROM (and GApps) onto your sdcard (sdcard must be exfat or fat32, NTFS not supported)
  2. Install fastboot and adb on your PC, e.g. from here
  3. Enable developer options and in there select to unlock your bootloader by enabling OEM unlock and enable USB debugging
  4. Connect your PC to your tablet and run
    Code:
    adb reboot bootloader
    using adb on command line. The tablet will reboot into bootloader mode where you will only see the Lenovo logo. Now you use
    Code:
    fastboot oem unlock-go
    to unlock. This will factory reset your device
  5. Don't setup, cause you will need to format your tablet later again. Shutdown tablet. Hold volume up and power button to start to bootloader
  6. Then run
    Code:
    fastboot flash recovery twrp-3.2.3-0-<your-filename>.img
    to flash TWRP
  7. Select with volume buttons "Recovery Mode" and press power button
  8. Select to write to system, otherwise you can't flash ROM
  9. Backup at least system and boot partitions to your sdcard cause you will wipe data in next step. Choose "System Image" for the system partition backup.
  10. Format data using this tutorial
  11. Flash ROM
  12. Optionally flash SuperSU or Magisk in TWRP which should install system less. Keep OEM unlock enabled if you flash or modify anything
  13. Restart

Mounting system rw
This is impossible on our tablet. The bootloader enforces verity check, which causes this issue.
The only possibility is to modify bootloader, what is dangerous and requires good knowledge.
there is a workaround using magisk with a mod. which mounts your system rw on mount:

Please don't support Lenovo and buy their tablets
Code:
[I]Updates vary depending on the model where our tablets receive Android and security updates after the introduction. 
We announced Tab 4 10 Plus in February 2017 and since then it has received seven OTA updates. 
However, this model has reached the end of its update cycle and will not receive any more updates in the future.
- Lenovo (2018-05-11)[/I]
Just seven updates and not even one major upgrade, please don't support them.

Reporting bugs
Please tell what mods you are using and what tablet variant (TB-X704F or L or ABCDEFGH..)
If your tablet doesnt start:
go to TWRP. use file manager, go to sys/fs/pstore, copy the files and upload it here.
if your tablet starts and bug appears later:
go to TWRP. use file manager, go to sys/fs/pstore, copy the files
start your tablet normal, let the bug appear, enter adb root
use adb logcat and adb shell dmesg, copy the content to a text file and upload here

Nova doesn't work

Fresh install. Nova home is unable to read screen rotation. Everything else seems fine.

Also the tablet no longer reads usb sticks. The same stick 2gb fat works fine on my phone with the OTg adapter. Lenovo says format not supported.

I assume 704 won't run on tab 10 606F.
That lenovo own bloatware is using up 1.6gb idle of the available ~1.9gb of ram and has some stupid aggressive app killer and unremovable bloatware.

I successfully installed and used Lineage OS on my tablet and have been using it for some time with no issues. However, I am planning to sell the tablet (bought a newer device). How do I remove my data from the tablet before handing it over to a buyer? With the stock OS, it is trivial, but I am not sure what to do with the rooted device.

Dear members, Hope you are all fine. I am new to install this firmware to my lenovo tab4 10 701LV softbank Japense device but i failed to install TWRP and run it on my device. I think the problem is i dont know how to root this device.

Is root is must to do before install this twrp in my deivce?
I am able to successfully upload twrp on my device adb but my device just restart to normal. It didnot went to TWRP bootload.

Is there anyone help me to install this firmware to my device.


Thanks very much.,
Zayad Mohsin
