[ROM][UNOFFICIAL][9.0][TB-X704F/L] LineageOS 16.0 for Lenovo Tab4 10 Plus
- Thread starter yener90
- Start date
Ah right, I understand now.
But, in my mind that would be like trying to re-invent the wheel.
But a good way to learn.
how do you guys revert to stock rom i tried everything without success and smart assistant needs internet wich I don't have right now. i already downloaded the stock firmware but my pc cant recognize my tablet even though i installed qualcom drivers
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.

x704f latest firmware s000056 181015rom pubg mobile and pubg lite also get kicked out of the game or the device is restarted. Does anyone have this problem?
Will this work on X304L?
Will it work with lenovo X304L?
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

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)

ROM
TWRP (Use this for TB704L too; you guys don't need 4g in recovery)
You can also get the latest ROM updates from codeworkx here:

Bulids are same, just update.
Older downloads
Optional downloads
Dolby Digital Plus (use the TWRP one)
GAPPS (use 9.0 arm64; I suggest using pico variant)
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
Just seven updates and not even one major upgrade, please don't support them.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.

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.
It would be nice to reset to the original Lineage OS state without any user data. Like before handing the tablet to the buyer, remove all personal and account info and let the buyer set it for themselves (assuming that the buyer may not be technical enough to do it on their own).
How do I get the ctsprofile to work? It is failing and I can't get the square reader to turn on because of that perhaps
Dear all,
I've flashed stock rom for tb-x704v by QFIL.
It has lost baseband firmware. It is unable to recognize sim card, unknown imei, unknown baseband version and no Phone app appear in app drawer.
Any one can help me fix it, please?
Many thanks for your support.

Hello guys,
Would any of you have some 7.1 stock images for x704f and be able to share it with me? Lost mines and would need them to move on and reapply stuff from there.
Would be greatly appreciated.
Kind regards,

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
