FAQ
TL;DR: 100% of successful fixes in this thread used PhoenixSuit USB flashing; “press Vol+ and click Power several times” to trigger detection. [Elektroda, Freddy, post #16859391]
Why it matters: This FAQ helps Cavion Base 7.1 Quad owners recover from boot loops and auto‑reboot after a factory reset.
Quick Facts
- Allwinner-based Cavion tablets are flashed with PhoenixSuit (or LiveSuit). [Elektroda, gradek83, post #16859173]
- Rockchip variants use RKBatchTool instead. [Elektroda, gradek83, post #16859173]
- Successful PhoenixSuit flash ends with automatic reboot. [Elektroda, Freddy, post #16859391]
- SD-card image method stalled ~60 minutes for the OP; switching to USB flashing fixed it. [Elektroda, koks214, post #16858801]
- A clean PC without old drivers allowed PhoenixSuit to detect and flash immediately. [Elektroda, koks214, post #16860456]
How do I fix a Cavion Base 7.1 Quad stuck on the Android logo after factory reset?
Flash the official firmware via PhoenixSuit over USB. Power off, hold Vol+, connect USB, and tap Power several times until detection, then confirm two prompts. The device should auto‑reboot when flashing completes. “Press Vol+ and click Power several times.” [Elektroda, Freddy, post #16859391]
PhoenixSuit doesn’t see my tablet—what now?
Remove conflicting drivers and try a different PC with no previous phone/tablet drivers. The OP confirmed PhoenixSuit worked instantly on a clean computer. Driver clutter is a common blocker for detection. After a successful flash, the tablet rebooted normally. [Elektroda, koks214, post #16860456]
Should I flash from an SD card or use a program?
Use a flashing program over USB. The SD-card image method stalled for the OP, while program-based flashing succeeded. An expert advised, “Upload using the program, not cards.” This path avoids long hangs and improves reliability. [Elektroda, nutergsm, post #16859073]
What is PhoenixSuit?
PhoenixSuit is the official Allwinner flashing utility referenced in the linked instructions for this tablet. It loads .img firmware files and initiates a low‑level reinstall over USB for recovery. It is the recommended tool in this thread. [Elektroda, brekofra, post #16859176]
What is RKBatchTool, and when would I use it?
RKBatchTool is Rockchip’s flashing utility. Use it only if your tablet’s chipset is Rockchip. The thread cites RKBatchTool for Rockchip and PhoenixSuit/LiveSuit for Allwinner, avoiding cross‑use that will fail. [Elektroda, gradek83, post #16859173]
My Device Manager shows “Alcatel ADB Interface”—is that a problem?
Yes. That indicates a mismatched driver that can block PhoenixSuit detection. The OP saw this and PhoenixSuit could not load the image. Switching to a PC without extra drivers solved it. Uninstall conflicting drivers first. [Elektroda, koks214, post #16859276]
Can you give me the exact PhoenixSuit button sequence?
Yes, follow this three-step sequence:
- Power off the tablet; open PhoenixSuit and select the .img.
- Hold Vol+, connect USB, and press Power several times until detection.
- Release buttons; answer Yes twice to start flashing; it reboots when done. [Elektroda, Freddy, post #16859391]
What if the progress window sits for an hour with no change?
Abort the SD-card method and switch to USB flashing with PhoenixSuit. In the thread, the SD image screen stayed unchanged for about an hour, indicating no progress. Moving to PhoenixSuit resolved the stall. [Elektroda, koks214, post #16858801]
Why does the tablet power back on by itself and loop to the Android logo?
That behavior matches a soft brick after reset. The device briefly powers off, then auto‑boots into a loop at the Android logo. Firmware reinstall via PhoenixSuit corrected this for the OP. [Elektroda, koks214, post #16858537]
Do I need to enable anything in Android before flashing?
No. The device can be inoperable and still enter the flashing mode. PhoenixSuit uses a hardware key combo to trigger detection, then performs a low‑level flash without prior Android settings. [Elektroda, Freddy, post #16859391]
LiveSuit vs. PhoenixSuit—does it matter which I pick?
Both target Allwinner devices. The thread points users to PhoenixSuit for this Cavion tablet. Staying with the tool recommended alongside the provided firmware image avoids compatibility surprises. [Elektroda, brekofra, post #16859176]
I can’t load the .img in PhoenixSuit—what causes that?
Driver conflicts or a corrupted download often block image loading. In the thread, the .img wouldn’t load on one PC but worked on another without old drivers. Reinstall drivers or try a clean machine. [Elektroda, koks214, post #16859605]
What’s the success indicator after flashing?
PhoenixSuit prompts twice, performs the flash, and the tablet reboots automatically on success. You don’t need to manually power it after a successful operation. “After flash is complete, the tablet should reboot itself.” [Elektroda, Freddy, post #16859391]
Any edge cases I should know before starting?
Yes. If your chipset isn’t Allwinner, PhoenixSuit will not help; use RKBatchTool instead. Also, stale phone drivers (e.g., ADB) can prevent detection; remove them or switch PCs. Both issues appeared in this thread’s troubleshooting. [Elektroda, gradek83, post #16859173]
What’s the minimum I need to start flashing?
You need the PhoenixSuit program, the correct .img firmware, a good USB cable, and the Vol+ and Power buttons. No Android access is required because detection happens at a low level during connection. [Elektroda, Freddy, post #16859391]
Was a full recovery achieved in the thread, and how?
Yes. The OP recovered the device by flashing the downloaded .img on a second PC that had no prior drivers. After flashing, the tablet booted normally. [Elektroda, koks214, post #16860456]
