Root Things not to do

[cicciocant]

We can make a list of "things to do" absolutely?

For Example:

a) DO NOT turn your secureflag ON unless on a stock,signed hboot.
S-ON with an eng signed or patched hboot will hard brick your device immediately.(read: permanently bricked,unrecoverable). In other words,ONLY use the writesecureflag 3 command AFTER running an RUU. never before.

b) NEVER install a S3 ROM on your S4 [SNAPDRAGON] device ! You will brick it.
How can you recognize ROM for S4 and ROM for S3?

Original ROM:
For S3:
RUU_VILLEC2_U_.........signed.exe

For S4:
RUU_Ville_U__........signed.exe

Cooked ROM (for example):
For S3:
CM10-20130421-UNOFFICIAL-villec2.zip
[ROM][S3] BackToBasics_v3
miui_villec2_3.4.16_adlkjfsdfj_4.1.zip

For S4 (for Example):
ROM][S4] Android Sense Best Stock v3.0 | Jelly Bean | Sense 4+ | BEST JB !
CodenameLungo_onesCM10.1_20130419.zip
ville_PAC_JB_4.2.2-v22.1.0_20130416-203856.zip

c) Do not try to downgrade your HBOOT.img unless you are S-OFF or did not install JB OTA [reported to be SAFE]

YOU WILL brick your device : forever !

But as this is in the One S forum, that advice is perhaps redundant here

There is a S3 (processor) version and a S4 version of the One S. It's not referring to the Galaxy S3, but the processor version of the One S.

 

[Hadron]

Ah, oops - didn't know there were two processor variants of this handset

going to the dark side here, but... don't ever drop your htc one s in water [glass of water, toilet, sink or any..] -> you will most probably lose your data, your device will not work and you will see fish swimming on the other side of the screen

I read thath flash RUU with supercid may be dangerous (hard brick). It's true? How Can I proceed?

 

[razvan06]

well... supercid is what allows you to flash ANY RUU[older, newer and for any carrier], but i would suggest to be careful and flash the one for your device model

OTAs with superCID have proven fatal,but running RUUs is safe,as long as they are for your device(i.e. dont flash a one x ruu on a one s )

running an ruu while super cid and s off will let you run literally any ruu that you like.

running them while s on,they will fail if other criteria are not met(CID is only one of many checks)

not in any case,have i heard of an ruu killing a device.
