Root [AT&T] Dev RUU on AT&T variant?

loyal,youll need s off and either supercid or developer cid to run the developer ruu. it should work fine on your att device :cool:
 
Yeah I might give it a go.
I can change over to the developer cid.

I wonder... If I used the dev ruu would I be able to get their otas normally and stuff?
Would I essentially have a dev edition?

yes,you would essentially have a developer edition,the hardware to my understanding is identicle.

you would always be able to run released RUUs,but recieving dev edition OTAs would depend upon the model number(product number)

i dont happen to have a dev edition getvar all,so im not 100% sure. if the model number happens to be the same as the att(712000) then id imagine OTAs would occure without a hitch if you stayed stock and kept the stock recovery.

i found on my one s,that the t mobile product number kept the unbranded europen software from OTAing. it would check,find update,and download OTAPkg,but fail when it tried to install.
 
Saw This I think it clears things up

The 2nd cid isnt needed for anything. No advantage to changing it. Only disadvantage of possible brick. I have ATT branded phone. Hex edit is not needed for anything for me. I successfully installed a ruu, OTA and changed signal icons all with fastboot oem writecid. The 2nd cid that required hex edit you speak of has always been CWS__001 and has never changed on my phone. I installed Older Dev edition ruu (1.29.1540.3), then relocked bootloader and changed cid from supercid to BS__US001, then checked for updates, downloaded and installed the latest dev OTA (1.29.1540.16) successfully while still having CWS__001 cid in the 2nd location. With 11111111 as the fastboot cid and CWS__001 as the secondary cid i get ATT icons when using 4.2 roms. If i change from supercid to BS_US001 in fastboot, icons change to international style. If i change it to tmobile cid i get tmobile icons. You can manipulate icons without changing the 2nd cid.

I actually figured that out when I was looking at a decompiled framework.
There are quite a few icon packs in the framework that you can enable with little effort.

I was actually pointing out the fact that he installed the developer RUU and did the OTA update on an AT&T model by only changing the CID in Fastboot ... the icons were just a side effect.

I installed Older Dev edition ruu (1.29.1540.3), then relocked bootloader and changed cid from supercid to BS__US001, then checked for updates, downloaded and installed the latest dev OTA (1.29.1540.16) successfully while still having CWS__001 cid in the 2nd location.
