I can't seem to get October release to work. Flashed ROM than gapps but get thrown back to TWRP. Reflashed back to August release and all is working fine. Any ideas?
[Thinkpad Tablet Android Development] Sparkrite:
After flash, before booting did you try wiping Dalvik and Cache ?

A bit more info might help,

What tablet?

What TWRP?

What Gapps?
[Thinkpad Tablet Android Development] Melhisedek:
Yes I did wipe Dalvik and Cache

Tablet is TB-X704F

TWRP is 3.3.1-0

Gapps is pico_20191113
[Thinkpad Tablet Android Development] Sparkrite:
Very strange, I assume you are 'dirty' flashing the latest ROM?

Try the version of TWRP I use, I have found it to be the most stable of them all.

[Thinkpad Tablet Android Development] cliffo76:
It looks like I've bricked my tablet (TB-X704F) trying to flash LineageOS.

It got to TWRP where I wiped the tablet then selected the ROM but from there it sat there for an hour doing nothing so I restarted it and now it freezes at the Lenovo logo.

I can get into Recovery mode and if I enter FastBoot mode my PC recognises the device but via ADB it is showing as unauthorised so I'm unable to do anything with it.

Would anyone be able to suggest if this can be saved or point me towards information on what I need to do to save it?

Regards,

cliffo
[Thinkpad Tablet Android Development] Sparkrite:
Well it's certainly not bricked.

Download the assistant and flash stock and start again.

https://support.lenovo.com/us/en/downloads/ds101291
[Thinkpad Tablet Android Development] cliffo76:
Thank you for that, it's back to stock.

How long should flashing of the LineageOS ROM take?

Mine, once again, just seems to be sitting there doing nothing with the blue lines going across the progress box but doesn't seem to be making any progress.

There is one message on the screen - "Warning: No file_contexts" - unsure if this is the issue?
[Thinkpad Tablet Android Development] Sparkrite:
That is the issue.

Flashing should take no more than 2 minutes or so.
[Thinkpad Tablet Android Development] Kidsnd274:
Does anyone know the changelog for the latest October build?
[Thinkpad Tablet Android Development] cliffo76:
All sorted now. I had to not do a full wipe before installing the ROM and this resolved the issue.

Looking forward to seeing how this ROM changes the experience on this tablet. Has got to be better than being stuck on Android 7.
[Thinkpad Tablet Android Development] Sparkrite:
Good to hear you're up and running.

But as I have said before most of the problems reported are by people not following the instructions correctly.
[Thinkpad Tablet Android Development] Sparkrite:
AFAIK just a security update.
[Thinkpad Tablet Android Development] AlUrNiMa:
ROM is running very nice for some weeks now. I've got only 2 Problems:

Dolby Atmos didn't work as described and Netflix wont work cause of the "Play Protect Verification" not working.

Anybody has some Workarounds for those things? I've searched already, especially the Netflix thing.
[Thinkpad Tablet Android Development] Sparkrite:
There is no need for any 'workarounds' as both function properly with this ROM.

You say 'Dolby Atmos didn't work as described', well can you describe what that means, please?

What exactly is not working with it?

Regarding 'Netflix' , where are you downloading it from and what version is giving you problems?

My suggestion would be to try different versions until you find one that works well.

I have both performing fully on my TB-X704V.
[Thinkpad Tablet Android Development] AlUrNiMa:
Mh. Weird then. I came from clean Stock etc.

CustomRecovery, Root and ROM all went perfectly (as described in OP)

Netflix shows only in Playstore "Not available for this Device" and if I install APK after starting it will say "Device not supported" (I found out already its because of the missing Play Protect Verification Status)

I had only AudioFX after ROM Installation. (I did install Atmos as described)

I will just try to Wipe and redo everything maybe it will work then. Everything else (4G, Bluetooth Audio, Wifi) works really good. :cowboy:

Will let you know If I can get it working. (Someone else reported the Netflix thing already in this Thread but there was no solution then)
[Thinkpad Tablet Android Development] tabbeber:
I was successful in getting Netflix to work with the "MagiskHide Props Config" Magisk module.

Open a terminal emulator (the ROM comes with one preinstalled, but you have to activate it from the developer settings) and type props. Edit the device fingerprint. I think you can do any, but I had great success with the Lenovo K6 fingerprint.
[Thinkpad Tablet Android Development] AlUrNiMa:
Thanks! I already found that out...was just too lazy to do it for now. :cowboy: Will try soon.
[Thinkpad Tablet Android Development] alekdavis:
Is it safe to assume that this update may not work on the TB-X704A model?
[Thinkpad Tablet Android Development] flyingboy2013:
I use the Chinese TWRP to flash op's ROM to TB-X704A successfully, but Dolby Digital Plus does not work. Can someone point me to a working DDP for 704A? Right now the voice is very low even put it to max.

Anyone going to have a go at building Android Q for the X704?
[Thinkpad Tablet Android Development] Ic2droids:

October build???

I have the capacity to screw up a wet dream.

Can I assume that people are now installing LOS 17?

The October build that a couple of people have referenced would only seem to apply to the build from which the referenced build is forked. Right? What are people installing?

I have TWRP installed via fastboot. Do I have to root this thing to install the ROM?
[Thinkpad Tablet Android Development] Sparkrite:
Don't know where you're getting LOS 17 from?

No you don't have to root to install this ROM.
[Thinkpad Tablet Android Development] gzdc:
hello dev where im going to place twrp file before code:fastboot flash recovery etc?
[Thinkpad Tablet Android Development] Sparkrite:
The command to flash TWRP is:-

fastboot flash recovery twrp.img

Replace 'twrp' in the above command with the full path (if not in same directory as fastboot) and/or name of the TWRP image.
[Thinkpad Tablet Android Development] gzdc:
recovery

i did flash recovery cmd says ok but it stays there on bootloader screen i cant move on to the next step. thanks in advance!
[Thinkpad Tablet Android Development] Frankyg:
I've been running the 09 June version of this Rom with no issues and wanted to update to the latest. I downloaded the rom to my downloads folder and re-booted to TWRP recovery. My SD-card isn't visible and doesn't show up when I select 'choose' storage'. I'm guessing it's probably the way I formatted the card when I first flashed the rom. 1st question - is it possible to make the SD-card visible in TWRP without formatting and losing data? If not, it's no big deal I'll slip another sd card in but wanted to know if possible. 2nd - not related - is anyone using a magnetic cover for the tablet that turns the screen off/on when the cover is closed/opened? Just checking it works before I buy a cover...

Thanks for the awesome rom!
[Thinkpad Tablet Android Development] Tirofog:
Yes, magnetic cover turns screen on/off here..
[Thinkpad Tablet Android Development] apotsi:
any link from ebay, ali, for a smart case for TB-X704L ? That yo have tried and works with the hal sensor in our tablet.

Mounting /system always fails for wiping/formatting/restoring on my X704A. It shows 0 byte in size. How can I find it back?

My first piece of advice would be to not multiple post the same question over different threads on the same forum, :-

https://xdaforums.com/showpost.php?p=81127217&postcount=1999

Now to try to resolve your issue, I advise that you use Lenovo Smart Assistant to restore your table to stock and start again, this time taking care what you wipe/format.

I asked this question before, but to be sure: I ask it again

I have a Lenovo Tab 4 10 Plus and I also installed the Lineage 16 ROM on my tablet but since 4 weeks, if I connect to my home WIFI network, it shows this error message: Connected, no internet

I have done this:

- Forgetting the network

- Resetting connectivity settings

- Resetting the tablet

- Resetting the Router

- Restarting the tablet

But it didn't solve the problem

But however, I can connect to one network, but that is not my home network

Is this a bug, or can I solve this problem?

And if I can solve my problem, how can I solve it?
[Thinkpad Tablet Android Development] ammarr:
Are you using some sort of firewall on your tablet?

There are some instructions here to disable the connectivity check: https://xdaforums.com/android/general/guide-how-to-avoid-captive-portal-t3927561

[Thinkpad Tablet Android Development] Sparkrite:
Basically all you're doing in following the instructions linked above, is instead of sending your logon (to the 'net) info to Google you are sending them instead to an 'unknown/unconfirmed' entity.
[Thinkpad Tablet Android Development] ammarr:
Just to be clear, I'm referring to the instructions to turn off the check. It seems like the check is failing on his tablet for some reason (maybe google is blocked at some part of the route).
[Thinkpad Tablet Android Development] Googole:
I think that it is a ROM problem, so I will reflash the ROM on my tablet
[Thinkpad Tablet Android Development] rock_shoxit:
I'm confused, but what is the best DDS patch to install?
[Thinkpad Tablet Android Development] Googole:
I have reflashed the ROM, but the problem is not solved

I have one option left: Install the stock ROM and if there is a new version of this ROM or even if there is Android 10 (Lineage OS 17)

Or I can try what you guys writed yesterday
[Thinkpad Tablet Android Development] Sparkrite:
I bet there is some sort of 'firewall' somewhere set up by default within your router/modem.

Try this, enable mobile data on your phone and set up a hot spot. Logon to this network with your tablet and see if that works.
[Thinkpad Tablet Android Development] Googole:
I have set a hot spot on my phone, and connected with it and surprisingly it is connected and has internet access

I have checked if the tablet was blocked by the router, and I deblocked it and first i thought it does not want to work, but finally after weeks it finally worked

Thank you for your time, answers and support

I appreciate your help!

Sorry for the duplication. How can i delete the other post? I didn't see such an option.

No it doesn't matter.

I really don't know why you will not follow the instructions given in the OP:-

Nowhere, AFAIK, does it state wiping/formatting the 'system' partition, ONLY data.

Also it says that to use the TWRP linked to, and not, as I suspect the Chinese version you are using.

Start from scratch again and this time, as I already advised,

do not deviate

from the well proven method for installation.

Posters who choose (for whatever reason) not to follow written instructions but rather make up their own is generally the reason behind an awful lot of problems presented here.

Good day. I own a lenovo tab4 10 plus TB-X704L. The display does not work well on the tablet. Soon it will completely stop showing the image. And I want to make an Android set-top box out of it. I bought the adapter "Unnlink USB-HDMI" for broadcasting images from the tablet. I bought a Bluetooth mouse. And I want to remove the display and I want to hide the tablet in the TV. Also installed lineageOS 16.0, TWRP 3.3.1, got ROOT rights through magisk.

Android 9 has a broadcast feature. Is it possible for the “broadcast” to remember the devices and automatically connect to the device, for example, as “Wi-fi” or “bluetooh”?

And can I make the tablet autostart when connected to a charger?

[Thinkpad Tablet Android Development] alekdavis:
Hi. This is my first time, so I may be doing something wrong, but after I run the adb reboot bootloader command (step 4), my Lenovo Tab 10 TB-X704A boots into this screen that reads:

START

Press volume key to select, and press power key to select

FASTBOOT MODE

VARIANT - QRD eMMC

BOOTLOADER VERSION -

If I run fastboot oem unlock-go, I get this message in the ADB command prompt:

< waiting for any device >

Any idea what I am not doing right?
[Thinkpad Tablet Android Development] Sparkrite:
You're missing the correct USB drivers.

Download and install them and then try again.
[Thinkpad Tablet Android Development] alekdavis:
Thank you, but which USB drivers do I need? I did not notice any mentioning of the USB drivers in the instructions. (And sorry if this is obvious; I'm a total novice here.)
[Thinkpad Tablet Android Development] Sparkrite:
Download and install Lenovo Moto Assistant, shut it down completely and then try your fastboot command.

This way you will have the correct drivers.

Download here:-

https://support.lenovo.com/za/en/downloads/ds101291
[Thinkpad Tablet Android Development] alekdavis:
Thank you. This helped, but now I cannot get into the TWRP menu. I run fastboot flash recovery and get:

target reported max download size of 536870912 bytes

sending 'recovery' (27544 KB)...

OKAY [ 0.650s]

writing 'recovery'...

OKAY [ 0.365s]

finished. total time: 1.017s​

Then I use the volume key to select Recovery mode, press the power button and it reboots into some sort of test menu with options to RUN ALL, RESET, REBOOT, and TEST REPORT (and items like 1 SYSTEM INFO, 2 KEYPAD BACKLIT, 3 LCD BACKLIT, 4 LED red, etc). I tried with the USB cord plugged and unplugged and it always gets into the same test (?) menu. Any ideas? TIA

UPDATE: After trying multiple times and a different SD cards (formatted as exFAT and FAT32), now, when I select Recovery mode from the Quick Boot menu, I get into the Welcome screen (I assume it's the default tablet setup). Cannot figure out how to get into the TWRP boot menu. Could it be that the the TWRP version is not compatible with X704A? Does the device need to be connected to the laptop via a USB cord when booting into the TWRP recovery menu? I run the fasboot flash recovery command every time and it always succeeds. The fastboot menu shows that the tablet is unlocked. What could I be missing?

Device: TB-X704A
[Thinkpad Tablet Android Development] Sparkrite:
You're missing a TWRP recovery file.

'fastboot flash recovery' is flashing nothing, the correct syntax is 'fastboot flash recovery twrp.img'

Where 'twrp.img' is whatever your twrp file is named.

This is all well documented in the OP.
[Thinkpad Tablet Android Development] alekdavis:
No, I specify the img file in the command per instructions (didn't include the file name in the post for brevity), so it's not the issue.
[Thinkpad Tablet Android Development] Sparkrite:
Please include ALL information in EVERY post, I am not witness to what you are doing and am not in a position to assume anything.

All I have, is what you say here.

What TWRP are you trying to flash?
[Thinkpad Tablet Android Development] alekdavis:
Sure. I am just basically trying to follow the instructions verbatim. The TWRP is from the link in the Downloads section (it takes me to https://twrp.me/lenovo/lenovo_X704F.html, I click Primary (Americas) under the Download Links section, which takes me to this version:

twrp-3.3.1-0-X704F.img

I read in another forum that for model X704A (the one I have), the only TWRP version that works is some Chinese version, but I could not find any download links for it, so I am going with TWRP 3.3.1-0-X704F as instructed in this thread. The commands I run are:

adb reboot bootloader

fastboot oem unlock-go

fastboot flash recovery "D:\some-path-to-downloads-folder\twrp-3.3.1-0-X704F.img"

And it all works fine. I just cannot get into TWRP recovery. I tried the using the Recovery mode option from the fastboot menu, pressing volume up (down, or both) buttons while pressing the power button, but it always takes me to the stock setup (or fast boot when using volume up + power button).
