Hi

Thanks for the great update, I've come from official firmware to this. I have TB-X704L

I've found 1 issue so far, looks like you cant call out or receive incoming calls. However mobile data does work and SMS.

Is there anyway to enable calling and VOLTE?

Thanks

When I installed LineageOS 16, there were issues with SD card, if it was set up as device space extender and I should set it up as normal SD card. I can't remember, what was the reason: device, bootloader or LineageOS itself, so I ask you :

are there such issues with lineages 17.1?

Thanks in advance!

DS4 on Lineage 17.1

Hi,

I have just installed Lineage 17.1 on my tb-x704f.

So far I am unable to get my DS4 to work. I have read the posts on vendor files and so on.

Has anyone got this to work, and how?

If not, is the only option to downgrade to LOS 16?

Btw, the controller connects, but does not respond.

So far everything else is looking very good.

I use LOS17.1 0731 build,the fingerprint can't be remove.My pad are X7O4L and X704A,the same problem.

Thanks for your work [MENTION=3208754]codeworkx[/MENTION]
[Thinkpad Tablet Android Development] jfaheyfan:
Try this workaround:

* Long-press the fingerprint you want to delete

* Delete "Name"

* Touch "OK"

* Touch the trash can

* Touch "Delete"

The fingerprint still shows after you touch "OK", but disappears when you touch "Delete".

It can changed though

Glad to hear that. Can you share with us the configuration of the audio patch and your installation order?

I have tried ALL configs possible, plus w and w/o SElinux.

I followed the Xiaomi tutorial for Dolby also, as I said, all configs in patch, and different installation orders. Without success.

I gave up, but if you can help us, it would be nice.

no reboot issues anymore

so after two months I can say, I'm very pleased... there have been no reboot issues anymore...:good:

the only thing my daughter said, was that she misses the "kids" account, because it had some nice wallpapers... and when she said that, I thought, may the issue have been related to the kids-account?? I mean, we have not had the issue anymore, so I'm guessing it's not hardware related... could it be that somehow the kids account got triggered or actived when not logged in to it, it caused the tablet to reboot... who knows, I guess we'll never find out ;)

anyway, thanks again, and hope the creator had a few drinks from my humble donation ;)

Hey,

i think its possible to revert back to stock rom by using an official Lenovo tool.

Just plug to USB and recover the device with it.

---------- Post added at 02:38 PM ---------- Previous post was at 02:25 PM ----------

I use this Version "lineage-17.1-20200607_140120-UNOFFICIAL-TBX704.zip" for a long time and almost every day now.

It runs very smooth and stable, i dont have any crash, bugs or batterie problems.

All functions are working properly, i use Magisk Canary mod for root, Busybox, debloater (to remove music fx and other stystem apps i dont need), fingerprint security patch data fix 0.0.0.1, Viper4AndroidFX.

Just go for clean install like explained by the guide:

HOW TO INSTALL LINEAGEOS

- Upgrade to latest available official firmware

- Upgrade to latest available TWRP |||| I use TWRP 3.4.0.0

- Download the LineageOS zip(s). (see Downloads)

- Copy the LineageOS zip to internal sdcard.

- Unlock bootloader and install TWRP.

- Boot into TWRP.

- Perform a backup of your current ROM. (Optional)

- RECOMMENDED: Do a factory reset! No support if you didn't! ||||| ADD from me: here i format the complete internal storage.

- Flash LineageOS.

- Optional: Install the Google Apps addon package. (see Downloads)

- Reboot

- complete LOS 17.1 installation

- Install Magisk Canary

- Always first install busybox

- What else plugins you need.

I dont recommend you to update software that works. I wont patch the last Rom, but even on updating the Linage OS I would go for a clean install from the beginning not only install the OS above it, then you will get problems with your plugins. For example the patch will install Music FX again and this will cause bootloop if you are using VIPER, then you need to uninstall viper again or uninstall magisk and install again.

It's hard to figure out what changes were made. It is also possible that some buges will be implemented in updates also.

Too bad there is no real changelog.
[Thinkpad Tablet Android Development] chr0m:
Hmm, just did a clean install of this and it's hanging during the "Connect to Wi-Fi" during setup. Not off to a great start here :)

Do I really need to upgrade to official fw first? I don't even know how to go about that anymore, I've had Lineage on here for ages.

Edit: It seems fine after a reboot. One thing though, is it possible to get access to system partition via a file manager? It freezes the whole tablet when I try
[Thinkpad Tablet Android Development] orjanraberg:
I upgrade from LOS 16.0 to 17.1 yesterday. I restored the stock ROM first using Lenovo Resuce and Smart Assistant v 5.2.0 (https://support.lenovo.com/se/en/downloads/ds101291). After that I installed TWRP and flashed LOS 17.1 with TWRP. What surprised me a lot was that my settings from the Lenovo Stock ROM were preserved in LineageOS. I had to to a factory reset after installing LOS to get a fresh start.

Everything has worked fine in LOS 17.1 so far. I had a lot of lag and hanging applications in LOS 16.0 and also high battery usage in sleep. With 17.1 performance is great so far. And battery usage in LOS 17.1 in sleep is not very high, but still higher than I had hoped for. AccuBattery reports 0.4%/h (21 mA) discharging speed when screen is off. On my old Sony Xperia Z3 Tablet Compact AccuBattery reports 0.2%/h (11 mA) discharging speed when screen is off and even though it has a much smaller battery.

[Thinkpad Tablet Android Development] chr0m:
What's the reasoning behind installing the stock rom first?

Will this fix my issue of not being able to access the system partition?

Edit: Looks it no longer freezes when accessing the system partition with a file manager.

I can't fault this rom now, everything seems to work, including getting Netflix from the Play Store after I installed Magisk and messed around with the build.props

Stuck

I know this isn't the exact right thread, but the exact right one hasn't had any activity in over a month and this same question hasn't gotten any replys in over 12 hours, so I'm hoping a related and more active thread can get me some help.

My bootloader is unlocked. Following these instructions, https://twrp.me/lenovo/lenovo_X704F.html, I seem to be able to flash any of 3 versions of TWRP for the tablet. 3.3 and 3.4 official and 3.3 from codeworkx. I say "seem" because I get no errors, but nothing I do will actually let me actually boot TWRP. I get the factory fastboot screen when pushing power and volume up, and nothing I chose there will start TWRP. I can start what I believe is the factory recovery. some of the options are to apply an update from the sd card, but I've used twrp off and on for many years and that isn't it. And "fastboot boot recovery.img" fails every time. Its as if its not there even though I have flashed it a dozen times! AND I can not root the thing without TWRP it seems. The tablet is still usable in stock form, but frankly, if that's the best I can do, this thing sucks. My end goal here is to put Lineage OS 17.1 on it. Or see how far into the field it will fly. Not sure at this frustrated point. HELP!
[Thinkpad Tablet Android Development] PureMAD4:
I think tfrom that link it's not the full install process. I was a while ago I did it but I seem to remember you had to boot straight to recovery 1st after the installation and then reboot the recovery within twrp for the installation to save properly
[Thinkpad Tablet Android Development] WisdomWarlord:
Do you mean this?

"Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install."
[Thinkpad Tablet Android Development] PureMAD4:
Think the 1st boot to recovery had to be straight from ADB after the installation then once on twrp from there reboot twrp once again from twrp on the tablet.

So if in adb and using fastboot I think it would be "fastboot boot recovery" to start twrp and then in twrp select reboot recovery again
[Thinkpad Tablet Android Development] WisdomWarlord:
Yeah, I do that, and it just comes back up to fastboot, which lets be chose recovery, but that causes the tablet to just finish the boot process and into android.

Upgrade lineageOS 16 to 17.1 - FM Radio not working.

- the tablet couldn't lock in 4G automatically after rebooted and settled down. I had to do it manually, and the signal came in not as strong compared to LOS 16.

- Call (phone) feature is not working as in LOS 16. I installed LOS 17.1 to see if this feature work or not.

- Casting is not working as reported in this forum. I haven't tried this feature yet, neither in LOS 17.1, nor in LOS 16 ROM.

[Thinkpad Tablet Android Development] vaio4ever:
About 5 minutes, but the wait time should be in LOS boot (with the LOS boot animation) and not in the Lenovo bootloader.

I'm trying some things now.

If I do a wipe data it works. If i update without wiping it stays in lenovo logo.

Maybe my installation is corrupt and I neet a fresh install.
[Thinkpad Tablet Android Development] MiltonFine21:
I had trouble the first go-round, especially with the restarts and the wipes in the right order and at the right time. It got stuck side-loading a few times. Maybe the factory wipe is essential. I've done a few other devices but this one was very fussy about things.

This is not the same issue, but maybe it will help. I installed the August update by mistake and then had to reinstall the November update. I did a Factory Data wipe in TWRP, restarted from TWRP menu to bootloader, and as soon I pressed restart, held in the power and the volume up buttons to keep it out of Lenovo logo screen (which maybe appeared for a brief moment). It returned to bootloader. Then I used ADB command fastboot boot <recovery.img> to boot back into TWRP. I did a factory data wipe again and then used the Sideload function in TWRP menu to flash November update and GApps. Started up pretty fast. TB-X704V.

---------- Post added at 11:12 PM ---------- Previous post was at 11:00 PM ----------
