Device: ECOPAD-branded tablet (retail rebrand), real ODM/build info shows COLORROOM/E30_Pro/E30_Pro
Android build: 15/AP3A.240905.015.A2/20250328
Chipset: Unisoc Tiger T606, board silkscreen reads "W30-T606-V2.Q"
USB ID in Android/recovery mode: 1782:d001 (Spreadtrum Communications Inc, Unisoc Phone)
Situation: In a giveaway I got a secondhand, was locked with a PIN from the previous owner,
I factory reset it not realizing this would trigger FRP since the Google account wasn't removed first. Now stuck on the FRP setup screen.
What I've tried:
- adb devices while sitting at the main recovery screen: nothing detected
- adb devices while in "Apply update from ADB" mode: detected, but only as "sideload" state — adb shell returns "error: closed" as expected for minadbd
- Looked into spd_dump (open source SPD flash tool) for a persist-partition erase, but I don't have FDL1/FDL2 loader files for this exact chipset/board and can't find public firmware for this ODM/brand
Does anyone recognize this board or have FDL1/FDL2 files for a T606/UMS9230 device that might work here? Or any other suggestions for an obscure white-label board like this? Happy to provide more photos/logs if useful.
