How to fix - TOOL DL image Fail! uboot is blocking by dl info
Ok I'm really happy to say I solved it, here are the steps as simple as I can make them:
Go here: to needrom.com and look for the A820 option 3. Its got a 3 at the end of the URL. Sorry if someone else could post the link that would be cool. Download only the recovery only.
Using SP_tools (The one you just downloaded) Load the scatter file. This is in the same folder as the SP_Flash Tool you just downloaded.
Power off phone. Remove battery and SD card and sims. Don't connect the phone.
Click the tick box da dl all with checksum
Hit the download button. Waiting for searching then connect the phone.
Green circle, wait 5 seconds, unplug and switch on.
E Viola! Now your phone is rooted and fixed. You might want to install unclemobile tools and update the recovery to something else, cwm 5+ or something. Then you you can install new roms from the recovery mode.
