yes it only work in download mode by vol- pwr while connecting to pc...it shows sprd u2s(DIAG) and sprd com enumerator at usb section.

i do not have backup of spl uboot and nv, but last year i was able to take backup of partitions like system, booot.img, recovery, data,modem, dsp,cache,fixnv1,fixnv2,runtimenv1,runtimenv2 from mmcblock s by cat command in adb.

now i am not able to get in to adb , recovery.....phone is not powering on i guess, only download mode..

Also not able to find same model ROM, i already posted 2 years back about any info of this phone...it has false name and details different from what i got after opening hardware. Actually cpu is sc6825c with samsung emmc and board is pc327en v3.0.0
