AMPE internal storage =0 and can't flash rom

I have a AMPE A85Q quad core android tablet running 4.1.1 os. Recently, I rooted the tablet using Z4Root despite warnings from my anti-virus AVG saying that Z4Root is a Malware. (I have used Z4Root before on another tablet before without problem). After confirming that I have temporarily rooted the tablet, I thought I return the tablet back to the original state by unrooting the tablet. Everything works fine until I shutdown and restarted the tablet the next day. The tablet factory resetted itself and I lost all my downloaded applications. I tried to download applications again, and it just hung. I then noticed the internal storage is zero. I factory reset it again via the tablet Settings, but the internal storage remains as 0.

So I started this journey get my tablet to the original state, after 2 days of research and experimentation on that subject matter, I have made some discoveries. There are many android users out there having this problem, ie, Internal storage is 0.

The solution provided by many experience users, appears to be quite simple, just copy /system/xbin/busybox to /system/bin.

As I could not access / directory, so from my PC, I downloaded Root_Explorer_v2.17.2.apk into my extsd card, and using my tablet File Manager to installed it. All went well. I then discovered my tablet does not have busybox installed. I thought perhaps, I can find a busybox.apk, I can install it via the extsd card. No luck, there is no a such apk.

I decided at this point, I must flash my ROM. On the website, they recommend backing all the data and apps before flashing, but I have already lost everything, and I can't install any new applications, so I can go ahead and flash the rom.

Since I'm doing this for the first time, I read many articles on the web. And, yes, there were users out there who had successfully fixed the problem by flashing the Rom.

My tablet rom version is fiber_8003-eng 4.1.1master 20130517 test-keys .

I found this rar from the AMPE home site.

szampe.com/UploadFile/file/2011-08/0335.rar (525MB)

(Chinese characters quoted from user codQuore posting)

The rar file contains

FOLDER : A8003QD 爱魅 改乐投风格、4K不支持4个窗口播放的软件20130427 (translated = A8003QD love charm happy to vote to change style, 4K does not support 4 Window Play Software 20130427)

------ and contains >>>> aimei_anpei8003_a31s_v2.0_4.1.1_20130429_[1024x768_ctp兼容_双Camera0308_gsensor兼容_ddr360].img

FOLDER : 全志A31升级工具安装 (translated = Allwinner A31 upgrade tool is installed)

------ and contains >>>> 升级指南（A31主控）.doc (translated = Upgrade Guide (A31 Master))

------ and contains >>>> PhoenixUSBPro_Cn_V330_20121204.rar

------ and contains >>>> PhoenixSuitPacket-V1_0003Beta.rar

------ and contains >>>> PhoenixSuitPacket.msi

At the same site, I also found the latest ROM 0381.rar (497.07MB) which has the same release date as my ROM. The rar file contains two folders:

FOLDER : A85?|?? contains aimei_anpei8003_a31s_v2.0_4.1.1_20130517.img (789.09 MB0

and FOLDER : -A31??? (As above the ?s represents chinese characters) contains PhoenixSuitPacket-V1_0003Beta.rar and ????A31???.doc (110.5kb)

PhoenixSuitPacket-V1_0003Beta.rar contains PhoenixSuitPacket.msi (12.33mb)

Why they have a rar file within another rar file, I do not logically understand. Maybe that's the reason, I can't get this part to work. I cannot understand the chinese instructions in the doc file.

If they know the recovery process requires a zip file, you would think it would be sensible to upload zip file rather than rar file. Anyway, I unzipped the files from 0381.rar using RootExplorer and copy the img, doc and msi files into a folder called 1dir. I then zipped the 1dir as 1dir.zip. I have to re-zip the files so that the recovery program can find the zip file.

In the tablet Settings>>Backup & reset>>Recovery Mode, I pressed Reboot into the system in Recovery Mode. Using the volume down key moved to highlighted “apply update from external storage” and select 1dir.zip from extsd.

...On my tablet screen display:

Android system recovery <3e>

Android sdk reversion:exdroid4.1.1_r1-a31-v1.36

Volume up/down to move highlight:

enter button to select.

reboot system now

apply update from ADB

wipe data/factory reset

wipe cache partition

apply update from external storage

apply update from cache

Install /sdcard/1dir …

Finding update package...

Opening update package...

Verifying update package...

Installation aborted.

And it jumps back to

reboot system now

Installations aborted. Hmm. Since I am only flashing for the first time, maybe I did not do something correctly.

. I tried removing the doc file and only zipped the img and msi file.

. Tried the earlier version 0355.rar. Same result.

. Tried wiping the cache partition first before flashing. Same result – installation aborted.

. Tried zipping aimei_anpei8003_a31s_v2.0_4.1.1_20130517.img with RootExplorer. Same result.

HELP,Please.
