good day ! TB-8504x bluetooth los 17.1 does not work. los 16.0 works. 🙏🏻
[Thinkpad Tablet Android Development] adazem009:
Same here... I think it depends on the firmware because it works for some people. I think I had Bluetooth working in this ROM a few weeks ago, but then I reflashed Oreo firmware and it stopped working.

yes TB-8504F works, but TB-8504X definitely doesn't work for everyone. F \ X are different.

For everyone having WiFi/Bluetooth/etc... issues:​

Here are some logs, @highwaystar_ru should take a look at them. In some cases there are SELinux denials, which cause WiFi and Bluetooth to break.

As a temporary fix, flash this ZIP file in TWRP: https://androidfilehost.com/?fid=6006931924117886495

It'll disable SELinux enforcing and fix the denials.

@highwaystar_ru Take a look at sepolicy, it needs a few fixes.

Which firmware are you using? Try to flash S001031, then RR.
[Thinkpad Tablet Android Development] JivanP:
Hello, all!

I cannot flash TWRP with fastboot flash recovery ...; I can only boot the image directly with fastboot boot .... Once booted like that, I cannot alter any partitions beside /sdcard (which appears to be in RAM, as any files written there with adb push do not persist across reboots). The other partitions, like /data, simply will not mount.

It seems that, because of this, I cannot flash the LineageOS image. Also, I had to alter the build.prop checks contained within the image in order to allow tb_8504x, which is what my device reports.

Any assistance greatly appreciated!

The rom just keeps trying to boot and is stuck on the Bootanimation on x304L any fix? The Lineage OS 16 rom was booting to recovery but this one just gets stuck at the bootanimation (Been atleast 15minutes since it has been stuck at this screen)

The rom in this thread is only for the lenovo tb-8504x/f , not x304L, please go to the respective thread for your device...
[Thinkpad Tablet Android Development] Mysteriouslog6:
sorry!
[Thinkpad Tablet Android Development] quattro527:
I thought I would chime in regarding the booting/bootloop issues. After spending hours rescuing, wiping and remounting /system, the unit just would NOT boot (either in 16.x or 17.x), I finally got it to boot doing the following:

1. Download and use the LATEST TWRP 3.3.1-1 as directed from this thread! The kernel and coding within this version did the trick, as I was still using an older version of TWRP (3.2.3-x) that I found for this device from another thread.

2. Power on the device into Fastboot (Hold VolUp + Power)

3. Flash TWRP (fastboot flash recovery twrp-3.3.1-1-TB8504.img)

4. Boot into TWRP--the touch screen may not be responsive--I simply pressed Power to turn off the screen, then pressed Power again--this allowed me to swipe and unlock the screen as well. If this doesn't work, try this a few more times--or use the mouse option as others mentioned.

5. MOUNT /system, /data, /cache

6. WIPE /data and format as needed

7. Reboot back into TWRP so that you can see your newly-formatted /data partition.

8. MOUNT /system, /data. and /cache again (do not mount as Read-Only)

9. Now go ahead and flash your ROM, GApps, etc--then Wipe Dalvik/Cache.

10. Reboot and you should now be able to boot. The process should take no more than 2-5 minutes tops.

*NOTE* For users inquiring about the TB8704v (Tab 4 PLUS), the same applies, PLUS you must also patch your boot image after flashing the ROM (boot-los17.1-tb8704v-xxx.img).

Good Luck!

[Thinkpad Tablet Android Development] mrskellington:
Beauiful. Fan-tas-tic. I cannot thank you enough for putting the effort to create this ROM. Everything I tested works fine, so no complaints. I was absolutely tired of the stock ROM stuck in the past with not even dark mode available. Now my tablet works faster, apps run smoother, I can use it in dark mode, and it even seems to charge faster and keep its charge for longer.

Thanks man. Truly.

The only catch up is to install the twrp and reload (after flash the recovery unplug usb cable and press volume up + Power button) until you see the twrp screen before you can really flash the rom
[Thinkpad Tablet Android Development] CountDracula120:
Hi I am using your TWRP 3.3.1.1 to wipe the system to install a rom but its stuck on "Formatting System using mke2fs" for 2 hours. I'm on the stock rom 8.1 also I don't have TWRP actually flashed since it replaces the recovery with the stock one on rebooting so I do fastboot to load TWRP each time. Is it taking this much time to wipe normal? What should I do? :(
[Thinkpad Tablet Android Development] ZONTAC:
reboot into stock recovery mount system than reboot into fastboot and boot into twrp and formate data,system,cache,delvik than flash rom.

hope it will work for you.
[Thinkpad Tablet Android Development] CountDracula120:
Nope its not working.. The stock one said mounted system then I booted into TWRP and its still stuck on wiping. It says "Unable to mount storage" in red letters in TWRP but after that it says updating partition so I thought it fixed itself? But it's still running forever.
[Thinkpad Tablet Android Development] ZONTAC:
strange never happened with me, you can asks to dev with log file.
[Thinkpad Tablet Android Development] CountDracula120:
Nevermind i fixed it and installed the rom :) i wiped data and cache first using factory wipe in twrp and then proceeded to wipe system, instead of wiping all of them at once from advanced wipe. I think it was something related to wiping system before wiping data. I dont know but still its fixed so im happy. Thanks.

Problem Unlock Bootloader ( "Waiting for any device" )​

Guys a help. I can not unlock the device with anything so that I can then proceed with its installation

LineageOS 17.1​

I have done everything from various drivers but nothing. As soon as I give the command "adb reboot bootloader" it enters fastboot and stops there. I command "fastboot oem unlock" does not move and pulls out: "Waiting for any device" . Is there a proper guide to do it all from the beginning? I have version 8504f

Hi folks,

I'm in the middle of installing the custom rom but i'm stuck.

when I try to install the image lineage-17.1-20210408-UNOFFICIAL-TB8504.zip with twrp twrp-3.3.1-1-TB8504.img but when I hit the install it just keeps doing it forever without a response.

I've tried what CountDracula120 suggested. wiping the data and everithing and than wiping the system. but the process stucks at "formatting system using mke2fs..." what should I try? any suggestions?
[Thinkpad Tablet Android Development] sesshou1:
Looks like I've found the solution, you have to go into the mount section and make the system partition writable.
[Thinkpad Tablet Android Development] sesshou1:
and an other thing that i've fond, the only way it works is if you unselect read only, put back the check into the system box select it to be read only and uncheck it agan, than select system again. don't know why it is hapening but it's hapennig.

I already have lineage 16.1 installed and working fine. I was thinking if this supports dd2tw then i should go for this. Otherwise i can experiment with re-compiling kernel source with ddt2w support in my existing rom.
[Thinkpad Tablet Android Development] Cobrag0318:
I have a TB-8504F according to the model sticker, and lenovo smart recovery tool. I grab the proper twrp and the lineage zip from here, boot into twrp, and do the wipe cache, dalvik, system, and data, after having to do the trick to repair the data partition. Then I go to do the install, and the script complains that it's only intended for (lists off the various TB-8504F and X variants) but says mine detects as a TB_8504x, and halts. Notice the underscore instead of dash, and lowercase x instead of uppercase. Otherwise, it'd match. But even more baffling is it's detecting as an X and not an F. Ok, fair enough, I go poking around and I find where it checks this in the script in the zip. I add in an entry, copying the format of the other entries, for the TB_8504x, with the underscore and lowercase x as it detected. Re-zipped it back up, copied to sim card, and repeated the install steps. It passes the check, Progress bar fills to what looks like 100%, last 2 status messages above says "patching system image unconditionally", and "detected filesystem ext4 for /dev/block/bootdevice/by-name/system", but just hangs like that indefinitely. Ok, maybe I'll try adb sideload method. Nope, that fails signature verification of course, because I tampered with the zip. So how do I get around this? Why am I detecting as an X when the lenovo tool detects an F and my label shows F, and the bit with the underscore instead of hyphen and lowercase x? Can someone legitimately add what it thinks my model is to the rom so I can install it?

I need HTC Shift US-English SnapVue liberated ROM because the custom ROM come with some bugs as backlight bug, no microphone bug and more.

If anyone can post a rapidshare link or other link then please let me know.

Yes, I also have the problem with all the new cooked ROM here. So I changed back to the original English ROM, I have to liberated from email again, but it is much more stable. However. the original ROM also have the noise sound problem!

ACtually, that means the sound driver is changed too. But I'm still unsure mic was working before. If it is, I might look for a way to make it work again.

My rom is stable because I start from the principle that the stock rom should be changed by light touch only.
[Shift Development] szjohnwong:
thanks a lot for your effort to make that ROM, I changed back to your ROM.

Actually I don't need GPS because no SD card support. I added 128 dpi, Chinese Font and Opera WM5 to your ROM.

I use the WM6 to surf when not at home.
[Shift Development] deprotector:
Thanks! Can we have a link for your ROM or for the post where we can read about it? Also your ROM come from an HTC Shift US version or what was the default language/keyboard on it?
[Shift Development] deprotector:
Also there is any way to know the latest SnapVue ROM version? Any way to find out what SnapVue version was installed in each HTC Shift even after we flashing the SnapVue ROM with custom ROM ?
[Shift Development] saiweb:
I think the latest ROM is 1.30.508.0, but you would see 1.30.405.0 more. Those two are not that stable. More Stable one is 1.22.x (Minor version number is not coming out from my mind currently). Thats what thaihugo used and it is WWE, which means US, but you have to tweak cabfile and keybd registry settings before you install anything and use with US keyboard. By default it is set to UK keyboard. Here is the ROM, http://xdaforums.com/showthread.php?t=420548 and don't forget to read page 2, it has the registry tweakings you may have to do.

Good Luck

[Shift Development] thaihugo:
I have posted the french version too. This one is 1.30. It is working properly too. Maybe I could try to change language from this version. I wonder the difference between this french 1.30 and the canadian 1.30.

Thaihugo, if I will flash your ROMN on my Shift you haver any ideea if the backlight level and microphone will work again?keep Also I understand that your ROM is UK version but my Shift is US version. I can change the keyboard in registry but this maybe affect other things?
