hello everyone,

i bought a Z1 C6903 was locked on French carrier SFR. I did pay for an unlock code, and now it's permanently unlocked.
i hate that SFR boot screen logo also these apps bundles came installed in it. so I want to debrand it with a stock/generic firmware.

before flashing, i need to make sure this won't damage IMEI and BASEBAND and render the phone's radio unusable.

i.e: Unknown Baseband or Missing IMEI

Please check the screenshots below, it has all the phone's info, including firmware version, baseband # and other crap from SFR carrier.

i'd appreciate any suggestion or help in what i should do in this case!

BTW: Bootloader unlock allowed: No :( (is it possible to make it Yes somehow?)

thank you very much.

No, no way.

To debrand your phone use latest flashtool and flash a FTF from Mega Collection for your Model C6903, there is no any issues as they are Stock and made for your phone. The R1B or something else is just a customization, not even noticeable.

Flash Generic/International and you are Fine.

Thanks, worked like a charm. I was branded and stuck with SFR apps too, now it's all good. "Mais ça, c'était avant" :good:

Can you tell me what is the website by MP please ?

So, with the generic firmware, no more SFR apps and the bootscreen is no longer the one provided by SFR ?

[FRENCH MODE]
Exactement l'ami, ça fait de voir d'autres Français ici je me sens moins seul lol
J'avais les même daubes d'app étant aussi chez SFR, j'ai flashé la ROM de [NUT] et mon bootloader est aussi locké, à ce jour je n'ai jamais eu de souci lié à la ROM et elle est même rootée :) .
[/FRENCH MODE]

Yeah that's it, it's a pleasure to see some Frnech friends, i feel loneless lol
I've had same app cause my provider is SFR as well, i've flashed the [NUT]'s ROM and i have a locked bootloader as well, as far i know i never had any trouble with this ROM and this one is rooted :)

sorry, it wasn't an online website.. it's a store in my country, i just sent the IMEI and he sent me the Unlocking code within 1hour...
and yeah flash any stock ROM and all the crappy SFR apps and customization will be GONE!

which android version or build you're in?
