SM-G900W8 IMEI null, baseband unknown - GSM-Forum

krazykipa · 12-04-2015, 02:18

Do not give me this answer:

"modem not work.
problem can be QCN, firmware, hardware"

Phone was working fine before writing QCN, now has unknown baseband.

Tried wipe EFS, reset EFS, and also manually restored modem + 3 EFS parts from working G900W8, still not working. NEED A SOLUTION!!!

Log from wipe EFS/NVM with latest software:

Then why you write QCN if phone was working fine? Just tell me why to not make same stupidity as you do

xerraco · 01-02-2016, 02:41

Maybe he is trying to expiriment, or think phone function will go better if write QCN.

Br,
xerraco

krazykipa · 01-05-2016, 00:16

Lol it is from customer, apparently was trying to enable 1700mhz AWS band like how it's done on other models with QCN.

I've been stuck with this phone for a year trying to fix... Maybe Z3X will finally provide solution?

krazykipa · 01-05-2016, 22:55

So anybody have solution instead of asking for donations in PM?

That phone comes with AWS already enabled. No need to do anything else. If the customer did it then how do you know that it actually worked prior to writing the QCN?

krazykipa · 01-06-2016, 23:37

Yes, I am aware. I have seen the phone working fine with my own eyes, better? Grab an S5 and do the same thing as him, it will break the baseband and nobody knows how to fix without original security backup.
