To make things clear I'm a noob.
Thing is i live in Trinidad and our carriers(Bmobile & Digicel) are both GSM, so i bought a Sprint HTC One android version 4.3 hboot 1.55.
I followed the procedures to Sim Unlock.
I'm not entirely sure which step i used but it was either step 1 of step 2 that I used before using step 3. Keep in mind that I never downgraded the rom yet but went ahead with the first 2 steps anyway.(Not sure if it cause the problem)
When I make a phone call it lasts around 30 - 50 secs
Then I get a No Sim card sim error, I believe.(It flashes very quickly)
I lose signal and when i get it back i get the SuperSU root access prompt.
When I grant or deny it, I get.
"chmod 666 /sys/subsystem_restart_properties/subsystem_restart_reason_nonblock"
I've followed the post from xerxes1987 on this guide with hopes to fix the dropping issue but it didn't work, i'm not 100% sure I did the correct thing though.
I'm currently S-on hboot 1.56
Running the stock rom Sprint_HTC_One_m7wls_4.06.651.4_RUU with equivalent firmware.
Can any one help, its a pain not being able to hold a conversation.
I haven't made a nandroid backup i only heard about it after doing the sim unlock. Yes, a noob i am.
Would gladly make a donation for a proper fix.
Desperation is kicking in.
