Hi, I'm all new to this so please any help would be much appreciated.
Why do I get this Error message

---Error: ---TotalBytesPerChunk Not Found. Set dafault PageSpare=2048/64 !!!
and why the IMEI/NVRAM button is disabled?


The phone is on stock ROM v.4.4.4 is rooted and with SuperSU and BusyBox installed.

Regards.

I have the Intex Aqua HD that uses the MTK 6582 chip. Since 1 GB RAM used for Applications was less, I changed my EBR1 and EBR2 to a new partition size of 3GB for Applications. Everything works except IMEI no. Restoring from Droidtools or even backuped up NVRAM.img does not work.

When I flash stock ROM back again then IMEI number can be set to original values without any problem.

So what is the problem with the IMEI restoring when the partitions (Only Application partition) have been changed.

Guys,

I have a LETV 2 PRO and I lost my baseband. I need to flash it again. Can someone with a MT6797 post a backup file I can try to use it?

A restore from NVRAM made by SP FLASH TOOL using the READ BACK option.

name: NVRAM
Begin Address: f300000
End Address: f7fffff
REgion: EMMC_USER

Please... I just need this file to make my phone workable again!!!!!!!

Thanks
