g900v no service after... - GSM-Forum

toutanje · 02-25-2015, 02:53

did the usual... wiped efs, write cert, matched meid with imei in dfs. set config to ruimonly... tried rewriting 2 different known good g900v qcn's and still no service... i did 3 at same time and 2 worked perfect last one was giving problems. cert imei is 100% working fine as seen on other 2 phones.

anyone have any other suggestions that i didnt try already?

I also tried reinstall 4.4.4 nk2 firmware and still no service

toutanje · 02-25-2015, 18:44

only thing that i did different in the beginning was to write a cert that starts with 35 and also matched it in dfs under meid. it wasnt working so i went back wiped and write cert that starts with 99 instead. dont think it matters but thought i'd mention it..

Why did you wipe the efs ? That's where you went wrong . And that's why there's no signal now nv items are damaged

It's is how I fix the Verizon s5
1 root
2 write cert
3 match meid
4 switch to global mode and put in your apns
5 profit

O forgot send 16 password and spc first before anything

i did other 2 same day by wiping efs and they worked no problem.. ive also done many, many more in past same way no problem. nonetheless, do you have nv items file??

flashing09 · 02-25-2015, 22:53

Read the nv items off your good ones and write to your one that's not working

toutanje · 02-25-2015, 23:02

already sent those phones back out dont have any.. maybe in the next day or two ill receive some more.

i do have good qcn backup file though i restored and still no service... shouldnt that work if i restored good qcn file?

toutanje · 03-01-2015, 21:30

well today i had new verizon s5 never messed with before, i read qcn from it and tried to write in phone thats messed up. no luck....

i made sure everything else was good such as matched meid. anyone have any other suggestions as to what could be going on if after i write 100% good qcn phone still no service??

Hello I'm having the same problem. Tried writing NV items from working phone. Still no luck! Here's what was done....
Wrote cert file
Matched in CDMA
No Signal
Wrote NV from working phone exact same setup...

Any assistance would be greatly appreciated. Thank you.

Just an update as in starting over from square A everything worked out in regaining signal.
1) Upgrade from NCG to NK7 which repaired EFS (Kept Root)
2) write good NV (Octoplus used G900A)
3) write good cert (Octoplus used G900A)
4) Match cert in CDMA WS (all values)
5) Install sim and wait 5 - 10 mins for signal
