Can you try the screen mirroring feature? I tried, it connected but no screen (just black screen) and no sound.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] yxo 6o6uka:
Ask and ye shall receive! lineage-19.1-20220918- is x-mas in september. Icons, buttons, grids are in the bag, thank you! All usable and super nice to have.

There are a couple of small caveats with the grid, probably the same cause. The big thing - alternative grids are now available, so below is minor.

- Long press in background -> WP and style -> # (app grid) -> Change the grid

- Repeat the above a couple of times, changing the grid selection and letting the screen to redraw

- Press Recent button - there will be as many recent Settings instances as many times you changed the grid. Should be one.

An apparent side effect of the issue is if you change default bottom icons (e.g. delete one, add others), when grid is changed so the bottom icons have to redraw, the buttons return to the default row.

I'm also trying to figure out the original design idea between the navbar and the taskbar. There are some non-intuitive things in the current build, will share thoughts after a bit more research/tests. Sadly I don't have a native android 12L. If anyone has a pointer to a functional reference for the taskbar, LOS or android, pls share.

To whom BiTGApps are better suited than NickGapps:

BiTGApps-arm-12.1.0-v1.3 is out, fixes the showstopper in the earlier version, works well with this ROM. Did not test OTA survival tho.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Ken Perkins:
Installation of Twrp.fota, NikGapps and Lineage went well. When I boot it becomes stuck in boot loop and just keeps restarting every time it says, "tablet is starting". The only way to have success is to have it plugged into charger, even though the battery has 90%. Any ideas what to try.

TIA.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] yxo 6o6uka:
I'd start by confirming the issue exist after a full charge and a clean install (wipe 2 caches, data, system before flashing los). After that I'd try isolating the culprit by flashing individual zip separately and restarting into recovery after flash before restarting into system.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Ken Perkins:
Thanks. Tried you suggestions. The OS runs properly. When I flash the Gapps it starts the problem. Tried 2 versions of Gapps from different sources and both fail.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] bierma32:
You have to flash LOS and Nikgapps at the same step with TWRP.

If you are already flashed LOS than you have to do a factory reset and than flash Nikgapps.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] yxo 6o6uka:
Yeap yeap... and can also try a quick fix with what you already have (los + gapps) installed - just wipe the 2 caches and restart.

If none of suggestion above work, los 18.1 from this developer + bitgapps is super stable/predictable, try that to rue out h/w.

The fact los is booting suggests it's a s/w config issue rather than battery h/w. Though if the battery is really old /worn out it could cause abrupt shutdowns (or restarts). US $13 for a new battery and 20 minutes with a guitar pick (this tab is very serviceable) will make the tab very happy.

Good luck

Hi,

I just wanted to say major kudos for this.

My sm t320 had been stuck on I think Android 7, whatever CyanogenMod stopped at. That stopped allowing me to update some apps like chrome, so I started messing with some roms.

I was about to give up on this old tablet because of WiFi issues I was having on the LOS 18.1 build, then saw this. With your recommended TWRP and NikGapps, everything seems stable.

Thanks again! I can't believe this tablet is on Android 12!

I've attached a screen record of how the taskbar can be toggled by long pressing the nav gesture bar when the settings are as seen in the attached screenshots. That's such a cool little thing, I love it.

Crazy mad props for the effort to keep these old tablets alive! I'm so happy!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] BennoMP:
What's the performance like? Is it much worse than LOS 13 or is it about the same?

Currently, I cannot join Discord voice chats for instance, it'll simply crash, but I'd like to see A12 if it won't be too much of a PITA for me to actually use it...
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] phoval:
A12 is not slow. I recommend to use it. It's stable.

hello. I hope someone can help me out. I have 18.1-20220822 build on my tablet. not sure if this build is by phoval or valera1978. I have a problem with YouTube videos buffering too long. The issue can be temporarily fixed by restarting the device but the issue will return after several minutes. I have tried clearing cache and data of Youtube, then reinstalling it, then installing an older version but none fixed it. I then did a wipe of everything except system. Issue still happens after reinstalling YouTube. Anyone here have any idea how to fix this? I'm thinking to just downgrade to 17 or upgrade to 19.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] bierma32:
@m33ts4k0z

Which Gapps did you have installed ?

Try Bitgapps.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] ALEX_ANDER:
Ok, signature spoofing is supported and works great with MicroG.

I also recognised that the UI works smoother with "Display size -> Largest" seted. In this case the icon bar on the bottom of the screen will turn off - I guess that's the reason for the little performance boost!

[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] pocketrule:
Encryption does not work, i've tried it once, but then gave up (lack of time). It should be possible, but I assume, TWRP should be fixed for that. One common error was that the data partition is too big and fills up the complete space for it, especially if you format data in TWRP. For the encryption, it's neccessary that there are some bytes left for encryption data.

To check the problem and MAYBE fix it you could try this out:

Fixing LineageOS encryption issue · Temp title

thomas.blarre.net

I've had this problem on another device and could encrypt it afterwards. Later, the fix was built in TWRP (format data).

But even if it works, you probably will have further problems in TWRP as it has to support the decryption of data partition.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Andrey Danin:
pocketrule thanks! My device is encrypting after fs resize.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] phoval:
Which size have you resize data partition? 12422400K?

Do you have US or EU tablet version?

We need to set BOARD_USERDATAIMAGE_PARTITION_SIZE in TWRP.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Andrey Danin:
I used 12140144K (12140160-16). Unfortunately encryption is still shows a progress bar (12+ hours). I use twrp-3.7.0_9-0-mondrianwifi.img (not the patched one from the first message). I will try the patched version.

I'm pretty sure I encrypted the device using lineage-16.0-20200411-UNOFFICIAL-mondrianwifi rom + twrp-3.7.0_9-0-mondrianwifi.img.

Will re-check both roms.

UPD1+2:

LE16+TWRP3.7.0 has same issue with encryption at the moment. Encryption is OK after FS resize fix.

UPD3:

this rom+TWRP3.7.0. I fixed fs (same size as for LE16). Device rebooted for encryption. I got password request on boot this time. But device won't boot and hangs on infinite boot logo (logo is animated).

UPD4:

LE19.1+TWRP3.6.2 (recommended in the first post) - no luck with encryption. FS size is large than FS size in TWRP3.7.0

LE18.1+TWRP3.6.2 - encryption works after FS resize.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] phoval:
Can you provide logcat during encryption fail on 19.1?

We need to fix the size of data partition in TWRP, do resizefs for now.

Can try on my own currently. I am working on LOS 20.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] pocketrule:
Can you provide logcat during encryption fail on 19.1?

I can reproduce what @Andrey Danin described:

- Trying encrypt the tablet without resizing /data results in a "reboot" to the ui

- After resizing /data, encryption starts, the device reboots and asks for the password to complete booting, but then gets stuck in the boot animation.

Unfortunately I cannot take a log at this stage, as the device is present, but does not respond (adb devices shows "<device number> unauthorized"

In TWRP you normally have to enter the password to decrypt data. With the patched FOTA version I've used (but I've seen that on official versions too), there's no dialogue for entering the password. TWRP log shows the following:

Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Updating partition details...
Failed to mount '/data' (Invalid argument)

Unable to mount storage

[Android Head-Units] Watch4user:
I have Junsun V1 head unit with LTE and canbox.

CAN settings is selected as "VW RZC".

Steering wheel buttons working good.

I have not connected KEY 1 and KEY 2. It`s not working. SWC is not working and that is ok, because CAN is working.

The problem is:

When I press volume UP on the wheel, volume down, next, prev - works good

When I press phone button on the steering wheel, the head unit open by default Bluetooth app.

So, when someone is calling to me, I can`t pick up the phone from the steering wheel, because Bluetooth app is opening.

Everything is coded in by CAN (VW RZC).

How to edit can settings? or how to upload new setting? How to change bluetooth for “pick up”?

Once again, please forget about key 1, key 2 and SWC.

Pure CAN recoding.
[Android Head-Units] rabbited:
I would like to know the answer to how to recode CANBUS settings. My volume up and down keys work as expected, but my phone key opens the Bluetooth app also and I want to turn it into a "next track" button and the hang up button into a "previous track" button.

For your problem, there is a submenu in 8878. I think it is in "Other" but possibly in CAN that reverse volume up and down. That should fix that problem. If you can't figure it out I will check next time I'm in my van.

[Samsung Galaxy Z Flip 4] larryk:
A family member is trading in an unlocked flip 3 for an unlocked flip 4, the flip 4 arrived on the 23rd. I popped in the sim card from the 3 and rebooted and could not receive calls. I placed a call from the phone and it worked, then I called it again and the call went through just fine, so I am thinking that it registered on the network and all is OK. A few hours later I called the 4 again, and the call did not go through... This is still happening today (the 28th) if I reboot the phone it works (for a few hours). I took the sim out of the 4 and put it back in the 3 and it works just fine. So, I don't know if the problem exists with the phone or with T-Mobile. It is on a pre paid TMO connect plan, so getting someone to look at this might be difficult as pre paid seems to be looked down upon with TMO.

EDIT: I just tried calling the old phone (flip 3) and again the call did not go through, but it did receive a text, and then I was able to call it....Sim card?
[Samsung Galaxy Z Flip 4] mzsquared:
I'd say call the cell provider, they might have to reset something - I had similar problem in the past and it was easily fixed.
[Samsung Galaxy Z Flip 4] blackhawk:
^This^ and try a network reset, clear SIM toolkit data.

Replace sim card if these don't work; handle the sim card like a stick of ram. They can be damaged by ESD. While they are dirt cheap, a partial failure can be a pain to chase down. Any failure can leave you with no service. ESD damage may show up immediately or days, months even years latter. Almost all sim card failures are due to ESD. Most techs mishandle them; use ESD handling protocols.

[Touch Pro, Fuze Themes and Apps] JM33:
Hey, I was thinking of this too! This would be awesome for panorama photos. Anyone seen anything like this?

It could be like the stadium photo shown about 3-1/2 minutes into this vid, http://www.youtube.com/watch?v=Jd3-eiid-Uw

Any devs up for the challenge?
[Touch Pro, Fuze Themes and Apps] mcdull:
panorama photos is not 3D... what are you guys talking about?
[Touch Pro, Fuze Themes and Apps] JM33:
Imagine viewing a photo in HTC Album that is zoomed in so that the border of the photo is outside the frame of the screen. Then instead of dragging you finger to pan around, you would just tilt the phone.

The photos are not 3d, but rather the photo is placed in a virtual 3d space. If you have seen the diamond hologram or VR hologram program and watch the video linked above, you will get the idea.

There could still be a standard full screen view, but when zoomed in, it would allow this type of panning.

Ubuntu Touch for Lenovo TAB4 8.

For more info - from Ubuntu Touch GSI:

This port of Ubuntu Touch is running on Halium 9.0, which is based on Android 9 (Pie).

NOTE: This port is not fully stable! Some features are not working yet, but it can be used as a daily-driver.

What works, what doesn't work:

Everything can be found here.

I'm looking for someone to test on TB-8504F. If it doesn't fully boot, it should at least reach the Ubuntu Touch splash screen.

How to install

Format data and flash the downloaded ZIP file in a custom recovery.

Thank you sir.

After install, not boot
[Thinkpad Tablet Android Development] adazem009:
Please send more information, such as which device you have. Is it TB-8504X or TB-8504F? Do you see the Ubuntu Touch splash screen or just Lenovo logo? Do you have the latest firmware (Android 8.1) installed?
[Thinkpad Tablet Android Development] K-BOX2022:
I own an 8504X, it stands on the Lenovo logo, I have the latest 8.1.0 Oreo firmware installed
[Thinkpad Tablet Android Development] adazem009:
Did you format data before installing? The correct procedure is to format data, reboot to TWRP and then install.
[Thinkpad Tablet Android Development] Dogleader6:
It tells me that the file requires lenovo tb-8504x but I have tb_8504x

I think this is a bug, as it should still be the same type of tablet I guess, just a dfiferent way of reporting the model? Is there a way I can fix this or tell it to override using TWRP recovery?

I have not flashed twrp, only booting via fastboot boot twrp.img but I don't think that would change anything
[Thinkpad Tablet Android Development] adazem009:
Possible solutions are to use a different TWRP build (there are a few different builds here on XDA), patch the zip file and edit the install script or wait for the next update (I'll try to fix it).
[Thinkpad Tablet Android Development] ZONTAC:
Use PBRP recovery if still problem persist than reflash firmware and than try again🙂.
[Thinkpad Tablet Android Development] Dogleader6:
Ok, will try that and report back if it works.

Kinda surprised that a non-mainstream tablet like the lenovo tab 4 8 is getting custom roms like this (but I'm not complaining)
[Thinkpad Tablet Android Development] adazem009:
Well, it depends on many things. The first one is that there must be some developers who want to work on the device. In Tab4 8 case it was @highwaystar_ru, then me reusing his trees and building newer Android versions. The second factor is the chipset. Most developers prefer Qualcomm over MediaTek, because qcom publishes kernel sources for their chipsets. And of course, if there isn't any kernel source from the OEM, all you can build/run is a custom recovery (TWRP) or a GSI (not on Tab4 8, but newer devices).

I think there are about 3 devs working on this device and there would be no custom ROMs without them.

Hi! TB-8504F(Simless) user here. It booted and it installed correctly with no errors. Anything I should test out? I used PBRP.

I'm having the same problem. I tried installing PBRP as someone suggested but it doesn't work well on my unit and keeps hanging the system on different tasks. Did this issue get resolved? I have the same problem with other ROMs as well
[Thinkpad Tablet Android Development] ZONTAC:
reflash stock firmware than start from scratch. (Before doing anything always backup your efs)
[Thinkpad Tablet Android Development] unkelsunk:
I fixed the problem so I could install using TWRP. Changed the install script to say tb_8504x in the description instead of tb_8504, and that solved it. Will try same with other ROMs since it seems like a typo that's been lagging on all installs.

Ubuntu touch started well and seems to work as intended.
[Thinkpad Tablet Android Development] pbanj:
is there a reason the system is read only? makes doing stuff in terminal impossible as it cant lock/write files

Ubuntu Touch doesn't use apt directly, use Libertine (in settings) if you want to install desktop apps.
