it´s seems as if there are more and more bricked Crystals every day.
For batch 1 fuser-invent posted the [HOW TO] Unbrick your Ainol Crystal .
To use this solution also for batch 2 und 3 it`s required an romdump of a fresh installed stock ROM.
Everyone with a WORKING batch 3 Crystal can help. Follow the instructions in the link in my post. It will look like here.
I have found another method, maybe a little bit easier.
Look below at "Alternative Method If The Above Does Not Work:". For this method you have to be root and have to install Terminal Emulator.
Alternative Method If The Above Does Not Work:
If this method does not work for you and all you need to backup is your recovery and boot images, you can simply do so as follows.
Note: Do NOT attempt to backup the system partition using this method as the system image it produces this way will NOT be a valid system image to be used later to restore your system partition. Use it only for the recovery and boot partition images.
If you are using ADB, connect your device to your computer via USB, launch a command prompt window on your computer and enter the following command:adb shell
If you are using Terminal Emulator instead, just launch it on your Android phone and enter the following command and agree to grant any permissions you’re prompted for:su
The remaining process will be the same for both ADB and Terminal Emulator.
Enter the following command:cat proc/mtd
You will get an output similar to this. Note that your result may differ from this one and you must proceed according to the output that you get, rather than the example that you see here.dev: size erasesize name mtd0: 000a0000 00020000 "misc" mtd1: 00480000 00020000 "recovery" mtd2: 00300000 00020000 "boot" mtd3: 0fa00000 00020000 "system" mtd4: 02800000 00020000 "cache" mtd5: 093a0000 00020000 "userdata"
To dump the recovery image to your SD card, make note of the first word of the line which says “recovery” in the end. It is ‘mtd1’ in case of this example but may be another entry for you. Now use this command, replacing ‘mtd1’ with the term that applies in your case, if different:dd if=/dev/mtd/mtd1 of=/sdcard/recovery.img bs=4096
Similarly, to dump the boot image to your SD card, make note of the first word of the line which says “boot” in the end, which is ‘mtd2’ in our case but may differ for you. Use this command now, replacing ‘mtd2’ with the term that is applicable in your case, if different:dd if=/dev/mtd/mtd2 of=/sdcard/boot.img bs=4096
That’s it – you now have recovery.img and boot.img backed up on the root of your SD card.
Then post your romdump, stock ROM version and the SN number of your Crystal here. Fuser-invent will try to help and find a solution.
