[Q] upgrade before root and flash? - AT&T Samsung Galaxy S II SGH-I777

I've got a used sgh-i777 on the way. I would like to know if it's best to do the standard Samsung upgrade before I root and flash or just do it from the original gingerbread?

Either way will work. You're going to flash and it will all be gone anyway. I'm told that framaroot will work on Gingerbread on this phone, so if you stay on Gingerbread, just make sure you use a Gingerbread kernel.

[Q] root. stock froyo

Just bought my daughter a galaxy 5 I5500. it came with eclair update 1.
I'd just like to know if I update to stock froyo can I root it.
If not do I need to root eclair before installing a custom cm7 or other. If this has been covered I do apologize.

Yes, you can root after stock froyo update with universal androot.
there is the best froyo ROM here:-

if you want swap etc.
The on-device programs didnt work for me. I am also in the Uk but i want to steer clear of custom roms for now. But i just managed to root it using Superoneclick. good luck
yes... SuperOneClickv2.1.1 did not worked for me...
but SuperOneClickv1.9.1 worked for my GT-I5503_XME_I5503DXJP8_I5503DXJP7_I5503OLBJP7

How do I flash back to stock if I have gingerbread bootloaders?

I'm currently using the Simply Stock gingerbread rom, and I flashed gingerbread bootloaders. I may want to try some of the new ICS roms coming out, but I want to be sure I know what I'm doing first.
Would attempting to flash back to stock 2.2 brick my phone with the gingerbread bootloaders? Do I need to revert the bootloaders first? Thanks in advance.
u can flash from the jvt rom you have now just fellow the guide in the op, you will have to flash the ics rom twice .but if u want to go back to stock use this guide and going back to stock would not brick you phone.

Gingerbread bootloaders are backward compatable with froyo and eclair no need to worry or change them. I prefer them because of the button mapping.
They also work with ICS. I have them and am running ICS Passion and have also tried all the other Vibrant and I9000 ics roms with them.
I also went striaght to ICS from DarkyROM 10.2.2 (2.3.4 JVQ)

OTA update/brick bug?

I just picked up a second SGS2 for my wife. She does not care about a bunch of custom stuff on her phone. She wants it to "just work right" as she puts it. I do however want to root it for the purposes of CWM rom backup and app backup. My question is, will the genuine update of ICS automatically bring the brick bug with it if I update OTA or through kies? I know I need a different kernel for cwm etc. Looks like maybe I want the stock rom from the Semi16 thread?

That's the way I would go.
Stock ICS UCLE5 with a custom kernel is an option. Stock Gingerbread with a custom kernel is another option. If you root and install a custom kernel, the phone will not update automatically, since it will not have the stock kernel.
My son's phone is still stock Gingerbread 2.3.4 with Entropy512's daily driver kernel which I installed for him way back in December.

[Q] back to stock, update to OTA ICS, then re-root?

I'd like to get ICS with working cameras on my Tab. I'm currently rooted running Task14 and looked at Task's latest stock ICS ROM with working cameras. But the rolling screen problems some are having scares me a little.
So my question is this: If I go back to complete stock (which would be HC) then get the OTA update, will I be able to root it using the same procedures outlined here at XDA? Just wondering if using the root method posted on XDA works while running the stock ICS ROM.
If this would work, do I get back to stock unrooted by just doing a factory reset, or do I have to use a specified unroot method?
Samfirmware.com has the stock rom for you download it from there and Flash via odin and you will have stock rom and no root........if u press reset it won't go to stock it will be on same rom ........hit thanx if I have helped

how to downgrade??

i recently had to get a replacement and without thinking i installed the latest update, I can still root it of course but i like to have a stock ICS backup to use Freedom IAP since its always been buggy on JellyBean for me. on ICS it works completely fine. can i either re-flash the entire phone? i used to do that all the time on Moto phones. or would just flashing a stock ICS rom work??

Best option is to go s-off. Then you can go from whatever rom you want to any other one easily.
If you have the latest update (3.16) and are still s-on, there is no way for you to go back to any ICS rom.
If you are on 3.15, you should be able to flash any ICS based rom or backup.
never mind
