TWRP touch and OTG USB Mouse Connection isn't working
TWRP touch and OTG USB Mouse Connection isn't working

Hello everyone! I’m reaching out with a problem. I have a Samsung Galaxy Tab A9 tablet, and I’m planning to install AOSP on it. For that, I decided to build TWRP for my device. I recently updated to Android 15. I read all the FAQs and followed the instructions carefully.
In step one, I used recovery.img as the base; in step two, I selected Android 15 from the list; in step three, I set the screen resolution to 800 x 1340; in step four, I specified the touch drivers as jdchipset.ko and chipone.ko. I set the TWRP build size to medium (Yes, much), and as a flag I specified
Code:
TARGET_RECOVERY_DEVICE_MODULES := jdchipset.koThen I uploaded the stock recovery.img and patch.zip (since my device is rooted, I copied the vendor folder; inside patch.zip I placed the vendor folder, and within it two more folders: firmware (with binaries) and lib (inside lib there’s a modules folder with the files chipone.ko, jdchipset.ko, and touch_common.ko)).
The build with working ID HcdBGnPRIRK0a8rNZlMI completed successfully, and I got a recovery.img image as the output. However, after flashing the compressed recovery.img through Odin3_v3_14_1_3B_PatcheD and booting into recovery mode, it turned out that neither touchscreen input nor mouse connection via USB/OTG adapter works.

Work ID HcdBGnPRIRK0a8rNZlMI has been re-queued. Download when its done and check the SD card detection.
Speaking of touch, how did you get the names of those .ko files you listed? Are they contained in the vendor folder of the firmware?

Then I verified it via
Code:
adb shellCode:
lsmodCode:
jdchipset 167936 0
chipone 311296 0
touch_common 36864 2 jdchipset,chipone Yes, I pulled the vendor folder from my rooted device. Inside it, under lib/modules/, I found these kernel modules (chipone.ko,jdchipset.ko,touch_common.ko). I included them in my patch.zip
under vendor/lib/modules/ along with the firmware binaries.

Unfortunately, after installation nothing has changed – touch is still not working, and USB/OTG mouse is also not detected.

(25-08-2025, 10:10 PM)Adilet Asqar I re-flashed the rebuilt recovery with Work ID HcdBGnPRIRK0a8rNZlMI.
Unfortunately, after installation nothing has changed – touch is still not working, and USB/OTG mouse is also not detected.
Redo another build. No custom flags and no reduction in size.
Lets see how that goes
