Hi, i have a Wolder Mitab Boston tablet, have a recovery (Android system recovery <3e>) without backup options. First of all i want to make a full backup of the whole firmware, with adb i only can backup apks, shared, i put adb backup -all -system -shared -apk and i only have a small backup of 200mb, no system files included so i have to make a full backup and i need your help for that. I tried online nandroid backup but i dont have cwm so this not worked for me, i tried romdump but when i have installed i run it and this error happened:
CANNOT LINK EXECUTABLE: romdump invalid R_ARM_COPY relocation against DT_SYMBOLIC shared library libc.so (built with -Bsymbolic?)
No idea what this means but this method dont worked for me, so i need an alternative method. Its very important to make the full backup before installing a better recovery. Thanks.
PD: If it helps the tablet it's rooted.
