I got around again to trying again with a n7100 device i got ages ago. seams this new version fixed the reboot loop :). how ever my sim not recognised. in about phone screen, baseband version is unknown. Is this a replicant issue, or could it be that in fact this phone is locked to a network? Been so long i forget if it was locked to a network, fairly sure i bought one sold as unlocked.
oh i did try cleaning the sim and using paper wedge to force it down more in sim holder. as some websites suggest. worked fine in my S3. which is what i have been using.
