HOW TO SOLVE INTERNAL DATA NOT ENOUGH:
With Link2SD full. And Minitool partition, insert a MicroSD in Windows PC and format with minitool, first partition as Primary and Fat32, second partition (assing 1GB) and format as primary and Ext4 or fat32, insert the microSD in the phone and turn on, open Link2SD and link to second partition as Ext4 or fat32, reboot, open again Link2SD and link all user apps to second partition (select move internal data).

Tonymananpa, my phone died! The first process step 1 ok but in the second step 2 fail and died! What can I do? Every time that I try to download preloader, something fail! What is going wrong?
i have followed the step .my lcd turn blank,no light . but my indicator lamp is on .. what happen ? it also vibrate when i press the lock key … plz helpp ..
hey tengo el mismo problema ya lo arreglaste ?
I'm tired searching roms for my s5 clone and i not had lucky. Your rom is the only i found that makes the phone semi-back to life…the lights start, charges the battery, vibrate…but the screen is black. With this ROM i got some info from droidtool and says LCD Driver IC : 0-rm68171_fwvga_dsi_vdo_tm. The tool says is MT6571 but when i make a backup, creates a scatter for 6572, i don't understand nothing.
You can give me some clue as to what I can do?
Thank you.
should be left marked the uboot options and preloader in flash sp tool or these are to be unchecked ?
hice todo como me dices tengo ese mismo movil pero la panatalla ahora no presenta nada pero parece que el android prende porque la pc lo detecta como un android encedido ?
I think the problem is lcd driver, but…how to change this lcd driver??? This is the question. This is the only rom it working for me, but screen still black, I need some help too…
