I have a bricked Blu Advance 4.0. Does anyone have or create a rom backup to use? Thanks.

Great guide and thanks for the effort in producing it.
It works perfectly.
I prefer to use Mtkdroidtools v2.4.3 because it has the option to backup userdata and cache, which makes it a full ROM backup.
The problem comes when attempting to restore using sptools.
The preloader is always missing in the list of entries after loading the scatter file and depending on what version of sptools I have tried, uboot can also be missing.
Without the preloader is seems impossible to restore back to the phone.
I did find a solution with one ROM and that was to copy the original preloader bin file from the original ROM flashed into the !Files_to_FlashTool folder.
This method worked with one custom ROM that I was testing but using the same methodology with another, it soft bricked the phone.
So it seems to me, unless am I missing something that the preloader is vital to the restore but mtkdroidtools is not able to backup/create the appropriate preloader file for a successful restore.

......i'm not able to make the back up succesfully. I've got the green square, so my phone is rooted but it takes a very long time and it's not coming any furter than:
--->>> Connect to device <<<---
ATTENTION! Requests for confirmation on the device screen are possible!
--- root shel it is received temporarily before reboot !
--- The preservation folder on the computer: C:\ANDROID\MtkDroidTools\MtkDroidTools\backups\ThL-W200S_140222_backup_140819-164926\
--- In phone files will remain in the folder: /clockworkmod/backup/140819-164926/
--- We keep blocks:
- preloader_and_dsp
- MBR
- EBR1
- nodl_pro_info
- nvram.bin
- userdata_nvram_only.tar
- nodl_protect_f.ext4.img
- nodl_protect_f.ext4.tar
- nodl_protect_s.ext4.img
- nodl_protect_s.ext4.tar
- nodl_seccfg
- uboot.bin
- boot.img
- recovery.img
- secro.img
- nodl_misc
- logo.bin
- EBR2
- nodl_expdb
- system.ext4.img
here it keep hanging and I have to abort this process then. Any idea what can be wrong?

It will take about 20 min to finish. Are you giving it enough time? And make sure you have 2gb free space on the drive and on your SD.

mmmm....finally got my backup. Version 2.5.3 did the trick, before i was using 2.5.0 and that one was not working for my MTK6892 THL W200s.
