Root [AT&T] Dev RUU on AT&T variant?

[LoyalServant]

More of a Scotty question but I am curious...

Anyone know if the dev RUU will work or do we need S-OFF for that too?

loyal,youll need s off and either supercid or developer cid to run the developer ruu. it should work fine on your att device

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

No No that has been de bunked by me lol.., No more hex editing needed, its dangerous!

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.
