[Q] What happens with root?

Hello XDA members
I was wondering, when the new android sandwich comes out, and you got a rooted and S-off HTC sensation. But not custom rom. What will happen to the root and S-off when you update to the new android sandwich?
Thanks

Want to know too ahehhe

We'll lose root but keep S-OFF I'd imagine

Cool, thanks for the answer

I have perm-rooted my Sensation and i was wondering when the new official update from HTC comes out will i be able to install it automatically like when i was not rooted or because i am S-Off it will not let me?
Thanks

i could be wrong but no you wont be able to perform an ota update. im only saying this because the last ota update failed because the update looks for the stock recovery in order to update the system. seeing that you are rooted i assume you have cwm installed and if this ota update does indeed look for the stock recovery than it will fail. the only way around this is to either instal a stock ruu and lose root or instal the stock recovery and again lose root. either way you are gonna lose root.

Could you give me a link where there is a guide to install the stock recovery?

If you check the development forum, there's a thread which has shipped roms in it. Flash one to restore stock recovery.

Depends. If you're just running the original rom which came on your phone but rooted, it should still allow ota updates, but you'll lose root (but keep s-off). If you're on a custom rom you won't receive an ota.
To OP, if you ran an ruu or ota of ice cream sandwich, as eddy says, you'll lose root but remain s-off. That said, a custom ics rom will probably come out weeks/months before an official HTC update

Well, when we got the RUU, we can extract and repack to our rooted ROM

It should be this if i am right ? http://forum.xda-developers.com/showthread.php?t=1074559

That's true, but we'll see aosp ics roms long before we have sense skinned ones, as cyanogen et al don't need to spend months porting frameworks.

Yes I am running the stock rom so I will receive the pta update. I know that I will lose root in every scenario if I install the stock ROM one way or another.
Thanks.

So i just flash one of these roms, without deleting cache or doing a reset ?

not entirely true. i was rooted on stock rom when the last ota rolled out. i tried installing it but it failed. i did a lil search here and found a few people mentioned that it failed due to cwm and they also mentioned that you should try flashing back the stock recovery. i tried that and it installed successfully. easy way to get the stock recovery is to instal the correct ruu of your rom. but as we all know it wipes out everything off your phone. i did find this guide which the stigx has asked for (sorry buddy didnt see you there ) which shows you how to extracted the stock recovery off of the ruu and than flash it back to your phone.

But if I need to follow your guide i have to have the OTA update file,w hich haven't comet out yet. What do i Do? It seems so hard to remove root and custom recovery :'(
But thank for your answer !

well the general idea is to get your stock recovery back without losin your data. so really all you need to do is flash your stock recovery reboot your phone and check for updates. if updates are available: system>about phone>check for updates, download the update and install. it shouldnt fail cause you have stock recovery instead of cwm. in short just do the top part of the guide and skip the rest cause you dont have the updates file on your computer.

So if i do step 1-12 I will have normal phone? Just like I started or do i still keep root?
Thank you so much for your hep !

You can also use this software to install the stock recovery. that way you don't loose settings by installing RUU

yes you do 1-12 but you keep root. the only difference is that you will no longer have cwm for flashing, back up, and all other goodies. but once you run the ota and it installs you lose root.
but have a look at the link frederikh just posted. seems alot better than the current method. im reading over it now

Thanks for the answers!
I think i will go with the link frederikh gave me But God bless you Divine! Thank you for your help !

[Q] Returning to stock [i9020a]

I just wanted to make sure that I understood the process of returning my phone to stock before I make a mistake.
All I've done since I purchased the phone was root it and unlock the bootloader. I have not loaded any custom roms.
So If I understand this correctly I need to:
1) Flash the Stock Image (which should include the stock recovery?)
2) Use fastboot to lock the bootloader
The reason I'm wanting to return the phone to stock is to receive OTA updates. I never use any apps requiring root, and don't plan on loading any custom roms.
I never did find a 2.3.4 stock image for the I9020A..

you should actually be able to get ota updates no problem. it'll just remove root every time you update.
it's probably not a good idea to lock the bootloader though cause if you ever want to unlock it again in the future you'll have to wipe everything from your phone. your best bet is to just flash stock recovery so you can install the update
i'm pretty sure that works, but hopefully someone else can verify just so you don't get some bad information lol

I heard the same thing about OTA updates. If you're phone is rooted and you're using the original rom, you'll get the update but you'll have to root your phone once again.
I haven't tried this myself so I cannot verify it.
It's just the word on the street, you know!

you need stock everything, so stock kernel, rom, radio, etc... the op should be fine to update if they flash stock recovery though. rooting is simple from there

Is that the method?

Thanks again kibmcz, so I just completed the flash, then did a fastbook oem lock.
Seems to be working fine except for one thing...
When I go into settings and hit Sound I get a Force close when I try and select a new ringtone...
Should I try reflashing again?

Didn't happen on mine (In fact im using a self rooted rom based on that exact stock zip) try doing a wipe in stock recovery.

after flashing that does it take it back to out of box condition?
reason i ask is because i bought a already rooted and unlocked one here from market place and i want to return it to stock firmware, radio, kernel and such to recieve OTA updates and what not.
your info is greatly appreciated

Using my zip yes... it flashes Bootloader, Radio, Boot, System and on first boot (and any other time recovery changes) Recovery is flashed. All you got to to is lock the bootloader and that wipes user data and usb storage.

hey man i appreciate you coming forward with a solution, ive yet to recieve the phone but wanted to prepare.
my goal is to flash everything back to stock and start completly over whereas i have no clue what method was originally used to root and unlock the bootloader.
when the time comes hope you dont mind a PM if i have any extra questions.

Just did the method using the stock ROM provided by kibmcz "thanks BTW!"
Phone is back to stock, working like it did when I first bought it. Had a little trouble with some Force Close issues but did a factory reset/data clear of the cache and all that before re-flashing, and it seems to be working Vanilla!

Basically, looks like Samsung is pulling the same sort of crap they pulled with the S3 bootloader to prevent status resets under the false pretense of security improvements.

Any chance of a step-by-step guide on how you did this? Especially what you deleted. Also is there any chance it would work if you wanted to go back to an older stock ROM? Reason I want/need stock is because I use the Bluetooth RSAP profile - unless anyone knows if this is included in the CM ROMS...
If you boot into recovery does it have any of the KNOX lines or is the recovery with CM different to stock? If so perhaps it would be possible to do something like (assuming I've understood correctly) : Root Phone -> Install CM -> Un CM the phone with a stock ROM?

NOT TESTED YET!!!! IT CAN BRICK YOUR PHONE!!
Instructions:
1. Download and copy ZIP to SD/ExtSD card
2. Check if you have BusyBox in /sbin, if not, copy and paste it from /xbin
3. Reboot into Custom Recovery (CWM/TWRP etc)
4. Install ZIP
5. Reboot

That info is going to come in handy to some users who bounce back and forth from Stock to CM.
Thankfully, I had not been tempted to do so and still have the old bootloader. Never going back to stock myself.

Hopefully it helps at least a couple of people.
The problem comes when you need to send your phone back to Samsung for warranty purposes.
Even if you have old firmware, reset flash counter etc. I can bet my bottom dollar when it returns from Samsung they would have flashed the new firmware and new bootloader to your device. They are great like that!!

Can i go back to cm11s this way?

Hi! My question is lame, i know.. But here it goes anyway, i couldn't find a simple and direct answer..
Is less than a week that i have this phone, and i've been reading a lot of guides of how to rollback to cm11s.. the thing is i've flashed the latest CM12S signed zip ota through CM Recovery, everything is fine as i'm testing it right now..
My question is: if i want to go back to CM11S (in the case that i don't like CM12S or have some bugs), can i just wipe data / factory reset and cache in CM Recovery, and then flash the cm11s signed zip?
I haven't rooted or unlocked bootloader, is it relatively easy from what i read around here.. but i wondered if i had to go through all those steps (unlock bootloader, custom recovery, and then flash) or just doing the steps mentioned before will work just fine..
Is it better to fastboot flash or through custom recovery is fine also?
Thanks in advance!
PD: I'm also asking what do you think about some other 5.1.1 Lollipop ROM, custom kernel, etc.. I'm kind of a flashaholic and i would be able to install the custom recovery if would be really worth it
PD2: sorry for the bad english, i'm from argentina

Just unlock your bootloader now, the longer you leave it the more difficult it'll be to backup your internal storage beforehand. You should really have it unlocked anyway as insurance against anything going wrong with your phone. Once you have unlocked it you can flash TWRP recovery, then the correct procedure to go back to CM11S would be to perform a full wipe (system, data, cache, dalvik cache) and then just flash the zip. As far as custom ROMs for this device go, there are many excellent options to choose from that offer extra customisation that you won't find on the stock ROM.

Don't we have to flash the firmware prior to flashing back to CM11s to prevent a hardbrick? I'm looking into doing this as well, so I'm just asking for my own clarity.

Thank you both, i believe that this week i'll have some time and unlock the bootloader and flashing the TWRP recovery right away..

Also, thanks for the clarification of the modems.. Will be looking after that and make sure not to miss that step if required :good:

Once you've flashed the ROM, please do share your results. I am still unsure if reverting from a Lollipop ROM to CM11S will cause issues with the radio and/or a softbrick of the device, as I've read that this "can" happen.

Reverting from Lollipop to KitKat won't brick your device, whoever said that is wrong, and would have caused a brick because they didn't know what they were doing. You do need to make sure you flash a KitKat modem though, otherwise you'll have issues with the prox sensor.

Yesterday, I stupidly turned off developer options as an app I was downloading said it wouldn't run with them on. Later on, I rebooted my phone, only to get FRP locked due to (I assume) previous Custom ROM flashing.
I tried for about 9 or so hours to sort it out myself with Odin and various guides saying I could flash ADB onto the phone and enable Developer Options from there. I have no idea how to fix it anymore and was wondering if anyone could help. I saw a thread somewhere that solved the issue, however, I can no longer find the thread.
As far as I know, all I can do is go into Download Mode to use Odin. Is it possible to fix my phone or is it completely bricked?

I'll give you one american dollar or 1 billionth of a bitcoin!
Sorry bro! I've always found persistence works best! So don't give it up.

You can fix it, you just need to flash a stock ROM that is either the same as the last stock ROM that was installed on it, or newer/has the same or newer bootloader.
If you try to flash an older one, you'll get an error in odin, because you're trying to downgrade the bootloader.

I just flashed a Stock ROM and it worked! When I'd done it previously, I'd been flashing the wrong ROM so nothing happened
Thanks for the help!

No worries
remember to enable OEM unlock in developer settings before flashing another custom ROM.
