[Android Q&A, Help & Troubleshooting] gripphon:
Hi everyone,

I also have this device and I'm willing to report my case because I'm also in search of the proper ROM for this device which I recently messed up (hardbricked) by flashing wrong ROM.

I was recently struggling to remove the malware and viruses that were installed by some of the in-built applications coming with this device. Tablet became very unusable, especially when it was using any kind of internet connection which was exploited by malware applications showing me tons of the ads and pop-up windows on screen.

It was impossible to download and install any application using Google Play store because tablet end in glitches running malware software in background thus occupying nearly all available memory. The only thing that would help for a while was rebooting it again and disabling any kind of internet connection, uninstalling and disabling malware and infected apps.

This would release some RAM but not for long. After few minutes tablet gets unusable and sometimes reboots itself. Each reboot would refresh and re-install removed malware software and same story happens again.

Then I came to idea to try to wipe all data using recovery mode, but even this didn't help. System was infected in its core.

Then I tried installing KingRoot, Stubborn Trojan killer, Malwarebytes apps using Wondershare MobileGO PC application for managing Android devices over USB. I was able to install manually downloaded .apk files of these apps to the tablet. But running this applications or trying to regain ROOT status would reboot tablet again and again giving me no other chance except to try to flash its ROM.

The main mistake I've made is not making any kind of current device ROM backup using MTK droid tool or any other kind of tool. Because I'm not too much in Android world, I though I could flash it (using SP Flash tool) with "similar" ROM content coming from different device but I was VERY VERY wrong. Doing flash with wrong ROM instead of my device ROM (which I didn't backup), I've made my tablet hardbricked, infact it is 99,99% dead because it doesn't want to turn on and charge anymore!

Please don't mess up Your device like I did with mine!!! It turns out that you must have 100% compatible ROM image with your device!!! To be 100% sure about Your device specs, You must previously read all information like firmware, motherboard, CPU, etc... using any kind of software (if your device is still alive) OR open it and see what's under the hood of device and make notes about it. For HOW-TO flash Android device research the Youtube/forums/blogs/google...

Anyway, there might be some hope if someone notices posts in this thread. My tablet can be decteded on PC once it gets connected over USB cable. In Win7 (32bit), after installing MediaTek USB VCOM drivers, it is currently seen on MTK USB Port (COM7). But once connected on PC over USB cable, it gets connected and reconnected on every few seconds. I've read somewhere on forum that this is expected case, but not totally sure. I'm still wondering why tablet is not detected under DA USB VCOM Port or Preloader USB VCOM Port as expected for flashing purposes in SP Flash tool.

I've already tried to use few ROMs and flashed my device but I couldn't find proper ROM yet. XWAVE brand cannot be found among few popular Android ROM websites.

After hours of searching I've found a thread about XWAVE XPAD G3 701 on some Vietnamese forum. The link is (message me)

After registering on this forum, forum revealed a link to the rar file containg ROM backup for this device. I've tried to flash my device with this ROM using SP Flash tool but it was still unsuccessful.

No matter how much I tried, I keep getting these 2 error codes (google them), 4032 and/or 1042. I didn't know if I'm doing something wrong or this ROM seems incompatible to my device version, but flash process is stuck at first stage in SP Flash Tool "DOWNLOAD DA 100%" (red bar).

Then I decided to look under the hood of my tablet and I found that my tablet's firmware is not the same as one in the ROM I've downloaded. This is probably why I can't properly flash this tablet (or I'm still doing something wrong or my tablet is 100% dead). Since this tablet has non removable battery, I've tried to keep pressing Volume - (and other key combinations) while connecting device to PC and before flashing starts.

Anyway, If anyone can make/share 100% compatible ROM image to my device specs for me/other people to try to flash it, that would be great. :)
