[Q] JB update and custom kernel

Hi all,
I'm sorry about my stupid question but I really don't know nothing about that . I had rooted and flashed my NS and installed the matr1x kernel (very good btw), and now I knew that JB will be available to NS. My question is, need I back to stock kernel to receive the update?
Thanks

You have to understand that installing an OTA (official update) on a rooted device regardless of what kernel can cause problems, as it did with my Nexus S before. I suggest you make a NANDroid backup at all times before you install any ROMs, official or Custom. You can also use Titanium backup and others.
There's still a slight while until the new JB 4.1 comes out. It's suggested that you install a Custom JB 4.1 ROM for your Nexus S as though you don't cause any problems. I think it's OK if you do it with the kernel pre-installed. But people always install the Custom ROM THEN they install the Kernel, I think installing a new ROM always overwrites the kernel, if it comes with it.
EDIT:
In short, wait for the JB Custom ROM and you don't have to revert back to stock kernel, when you do the update it will automatically overwrite. Most Custom ROMs come with Stock/ordinary kernels. So then the user can flash whatever kernel they like in your case, matr1x.
Wish you the best of luck, and I am waiting for the Nexus S JB to come out as soon as possible

Ota binary patches the boot image iirc. So it can get all messed up.

I didn't any backup before flashing a new kernel :crying:, so what can I do now if I want my stock kernel back?? What's a NANDroid (I know that is a tool but how can I do it?) ? Is Titanium bkp easily?

A NANDroid backup is a internal memory backup. You can create one by booting into Recovery (Power off your phone and Hold Power and Down on your volume buttons.) If you rooted your phone and unlocked your bootloader (that's what you had to do to flash a new kernel), you should be able to load ClockworkMod or TeamWin Recovery and do a backup of your phone.

There's one rom but it's a port from the SDK and the amount of major bugs is high so it's not recommended but you could try another custom rom meanwhile, I can't go back to stock after trying custom roms, like AOKP and Cyanogenmod 9. Make sure you backup your apps and some settings (not everything will be compatible between stock and custom so pay close attention to which system setting you'll backup) with Titanium Backup.

To sum it all up for you
There's a Jelly Bean release which is unstable and has no sound, and will not be fixed until the REAL version comes out.
NANDroid backs up the whole internal memory on the phone including the system, it can be done from clockworkmod recovery.
Titanium backup, backs up specific settings and information that you choose, available from the playstore.
You don't need to unroot or go back to a STOCK kernel in order to flash a CUSTOM ROM. DO not however flash a STOCK rom after rooting, as at times that can cause problems.
If you want to go back to a STOCK ROM after rooting a device, there's a way, check this guide
http://forum.xda-developers.com/showthread.php?t=1063664
and choose your Nexus S model: To acquire model, go to Settings - About - Baseband version. if it says I9023 at the start that's your Nexus S's model
Choose one of the Fastboot Stock ROMs and use the Fastboot method to flash the ROM. That is a good way to go back to STOCK ROM if anything bad happens
By the way you should expect the new OTA official 4.1 update for the Nexus S to be on your model's page.
NOTE: Using Fastboot to flash a ROM is very clean. However this will delete all your data and if you do everything correctly will lock your bootloader and unroot your phone. So use Fastboot only when you really feel the need to.
Cheers
and stay tuned for Jelly Bean :victory:

That means, when I receive the official 4.1 update notification, I should unroot my phone first and just install it after?

OK first off, do not install the update using the system update method from about, as that is a 100% stuff up if you're still rooted or on a Custom ROM.
However to update I think flashing a stock ROM but USING Clockworkmod works fine!
Someone please confirm, as I am not 100% sure
However what I am sure about is that if you run into any troubles installing your STOCK ROM using Fastboot is very very good and clean, however there are 2 things:
1. You will wipe everything COMPLETELY
2. You need the ROM to be in a fastboot format kind of way for you to flash it
There's a guide and everything for fastboot.
---------- Post added at 12:35 AM ---------- Previous post was at 12:33 AM ----------
Personally I will wait for a custom ROM for 4.1 if it doesn't take too long as that's guaranteed and will obviously be faster and safer to install on a ROOTED device.
Someone still confirm if installing Stock ROM while over Custom ROM while ROOTED through CWM is OK or not!?

Hummm, ok...
I'm already using the Stock ROM, I just flashed a new kernel, and I prefer install the stock kernel and unroot my phone. Just to let it clean.
After I install the JB official update, maybe I flash and root again, depends of Google :laugh:
Do you know where can I download a trust official 4.0.4 kernel from the forums? My phone is a Nexus S I9020AUCKJ1, Version Number: IMM76D
Thanks!!!

Install TWRP & CWM Side by Side & Radio Files?

I am trying to update my Radio/modem file with the JB Android 4.3 Radio file. It requires that I install CWM 6.0.3.7. Can I install this alongside my TWRP 2.6.3.0 installation or as I have read, it will overwrite my TWRP recovery mode? If it will overwrite, how do I switch between? Just reflash through ODIN using PDA? That seems like a lot of work and the possibilities of breaking might be high just overwriting Customer Recoveries?
If I would install this JB Radio for Android 4.3, how would I go back to GB? I can't find a single GB Radio/Modem. Could I use Radio files for GB instead of wiping and installing stock GB ROM [No Root, No Custom Recovery, but it includes the GB Radio/modem]. The reason I am worried about this, if I need to load my original stock GB 2.3.6 backup with root from my nandroid, I would need the original GB Radio and the nandroid backup/restore feature doesn't include that. All advice is greatly appreciated.
The Radio Does Not Get Backed Up By Cwm/twrp Backup(nandroid) Method.

Just flash it with twrp. It'll work just like if you did it with cwm.

I have read that some of the zip files does work with TWRP as well. However I am interested in using the following Custom Rom [SuperLite AOKP JB 4.3 v1.0]. That installation requires CWM 6.0.3.7, because it will prevent the infamous black screen reboot issue. What about GB radio file & installing on top of or installing side by side TWRP & CWM?

Pick a recovery and use it. Backups are not cross compatible. If you make a backup with cwm it won't work with twrp.
You can flash radios with either. Just pick one.

If you have not already installed a 4.3 ROM, then you are recommended (nay, required) to use CWM 6.0.3.7 to do the initial wipe and install, after that you can switch to TWRP for any flashing after that.There is something that 6.0.3.7 does to the data partition that TWRP doesn't, on the initial setup. Once that is done, it doesn't matter. Flash the JB radio when you flash the 4.3 ROM. And going back to GB if you need to is fairly simple, just follow Vincom's guide. There are lots of flashable zips of GB radios you can use.

I am still a bit confused regarding TWRP & CWM being installed at the same time or side by side. So, let me get this straight. If I want to install JB 4.3 ROM, I must first boot into ODIN, install CWM through ODIN, reboot, boot into CWM, wipe the system, reboot, boot back into ODIN, install TWRP, reboot, boot into TWRP, install the JB 4.3 ROM, and finally preform the last reboot. Is this correct & it won't break either of the custom recoveries? However rpr69 said "switch back to TWRP." Are you inferring TWRP & CWM can be installed side by side? If so, how do I access one over the other?
Regarding GB's radio files:
Which of the following links is the Radio/modem files? Is it the second one? I know of them is the official stock ROM and the other requires the OTA updates. However the poster didn't include the OTA updates yet...

I know you posted but its confusing, let me simplify, I hope:
im assuming you have either cwm or twrp installed, if on stock read this.
you cannot have two recoveries installed at the sametime:
recovery install procedure:
if not on cwm6037 flash cwm6037 with what ever recovery you have now and reboot back into recovery.
then flash any custom jb4.3 rom, preferably latest cm10.2 nightly found here and reboot rom at least twice.
if you like cwm 6037 stay with it, I don't, or else just flash twrp 2.6.3.0 w/cwm 6037 and reboot back into recovery or rom.
now you can just stay w/the cm10.2 nightly you flashed with cwm 6037 or flash any other rom w/twrp 2.6.3.0 which is now your installed recovery.
that's it you should not have the reboot problems on any jb4.3 roms.

above recovery install procedure is only if a jb4.3 rom on its 2nd reboot just has a black screen and wont boot into rom, but 2nd boot does usually take longer than normal upto a full minute.
if flashing a rom or restoring from nandroid(recovery backup) prior to jb4.3 and then later decide to flash a jb4.3 rom you need todo above recovery installation procedure b4 flashing a jb4.3 rom.
restoring backups only work with whatever recovery they were made with, you cannot restore a cwm backup w/twrp recovery and vice a versa.
newest versions of recoveries should restore backups made with their older versions.
why do u want an old radio, they will not work w/jb roms
old radios are linked in the 1stop sticky under "old stuff".
installing the radio has nothing todo with the recovery you are using.
flash jb radios for jb roms which happen to be all the current roms.
reread the radio section in the 1stop sticky.
I linked this post in the recovery section of the 1stop sticky

Thank you vincom for explaining the process of using both CWM 6.0.3.7 & TWRP 2.6.3.0 together. I am familiar with backups ONLY working with their original customer recovery. I didn't even think about older versions of backups (not) working with newer custom recoveries. Was there an issue working with older backups in the past?
The reason I need the old GB Radio/Modem files, because when I have to return the phone to stock & load up my old Gingerbeard nandroid, I will be able to return it back to AT&T with the original Radio files and the original Gingerbeard OS. Anywho, thank you for the GB radio. I really appreciate it!

u can return any phone that has any stock firmware, with our phones that would be stock jb4.1.2 and using odin would be the way to do it , link in my sig. this is assuming your carrier used the latest firmware as with att and rogers.

I am with AT&T and I never got the official ICS or JB through updates. Actually, I thought ICS was discontinue, because it was bricking phones. Thus the stock ICS & JB Roms here were ported over?

So if you're flashing 4.3 ROMs just use cwm? Went from twrp to cwm and back to twrp and am getting the same black boot screen on a slim 4.3 weekly.

To properly set everything up, you need to use the recommended CWM for 4.3, do a full factory wipe, and make sure that data is formatted. Then install the ROM and boot it up. Reboot to verify it works properly. Then you can go to TWRP 2.6.0.1 or later.

I've been using twrp since release and not had any issues why do we need cwm? What's the technical reasoning.
Sent from my XT1080 using Tapatalk

Didn't work
I followed this procedure exactly and it still didn't work.
I gave it ten minutes between boots and ended up having to pull the battery each of the three times I rebooted.
Fortunately I've gotten into the habit of making a backup before flashing, so it was just a loss of 45 minutes of my evening.
I was trying to get the latest CM10.2 Stable build. Has anyone gotten this thing to flash and work as well as 10.1.3 RC2 or 10.1.3 Final? This issue started for me with the second 10.2 Nightly.

Just NOW began seeing the replies to the main post. I don't have ANOTHER fresh install in me: I've already had to do that twice with the 2012 Nexus7 and once with the Skyrocket in the last six weeks.

[Q] Flashing Custom ROMS - Flashed to PagePlus

Hey Everyone!
Ok, so just over 3 weeks ago I had my S3 flashed to PagePlus because I thought I was in a little over my head to attempt on my own. 2 days ago I was under the impression flashing and interchanging between roms was safe. I rooted, installed TWRP, and flashed CM11. I broke my flash and I believe it was because I wiped. I reverted back to JB 4.1.2 from my Nandroid backup and my flash was still broke. Can someone please tell me if I should only wipe Dalvik, or what I should do so I don't break my flash again. At $40-50 it gets very expensive to continue re-flashing to PP. If there is only certain roms to flash could you please list them? Thanks in advanced everybody!

Have you resolved this issue? I too recently had my S3 flashed to PP while on Scott's CleanROM Seven http://forum.xda-developers.com/showthread.php?t=1832070. (pretty much a stock debloated ROM based on the latest Verizon released VRBMF1 Jellybean 4.1.2). I would like to try his latest CleanRom8 (based on 4.3), but I don't want to lose my PP flash.
Do you (or anyone else) know what should be backed up or omitted to prevent losing my PP settings?

I believe it had something to do with what the guy did to flash it. I kept breaking it with his flash. I flashed the phone on my own and I am running mastamoon's CM11 with working text, talk, and data. Flashing custom roms should NOT break a flash. Best I can say is give it a try. If it breaks I can remotely flash you talk and text again and you could look to Viper or Nevell for help getting data back, but once again it should NOT break your PP flash. Hope this helps.
EDIT: If you go to the rom in my signature there is a CWM swipe recovery in that thread. I am successfully running that right now. I personally like the layout of TWRP better, but seem to have more success with CWM and it seems like most if not all roms are supported by CWM recoveries.

Booted into stock recovery sch i535 4.4.2

So I was installing xposed installer today and instead of writing directly to system I had it go thru recovery to auto install. I thought it would go to the unoffical safestrap, as i'm sure everyone is aware you are locked out of the system recovery on the verizon varient anyways. What happens if I try to install something from there? And more importantly can I flash custom rom that way possibly revert to an earlier android version?
The whole thing caught me by surprise and Im not sure if I can duplicate it haven't tried. Just wanted to hear some thoughts on what this is.

You cannot flash anything from stock recovery except an update.zip file, you cannot flash a custom ROM from there, and you cannot revert to an earlier android version. This information is readily available in a couple of very easy to find threads in the S3 forum.

TWRP 2.8.7.0?

Has anyone one used the latest twrp recovery? I know know there have been issues with past versions.

Been working fine for me. I only use it for a little before flashing ktoonsez recovery. If you aren't having issues with your current one, really no need to change. I just always grab the latest when "starting over" from a full firmware flash.

Well I have used twrp recovery pretty religiously it has an good interface. Some find the Phil's CWM is good as will although I don't think that they is any more support for that, but there is one floating out there. I have never used SafeStrap. I believe that is used for lock bootloader which would be unnecessary for our Sprint phone which are unlocked.
