[Q] About flashing custom ROMs

Hi everyone!
I am fairly new with android and I just rooted my transformer last night. I was also able to install a custom ROM, revolver 3.11.1 (Honeycomb).
If I want to flash an ICS ROM (Revolver, Android Revolution or Codename), from a custom HC ROM, do I have to do anything else? Or can I just flash it straight away?
Based on what I've read, if ever I wish to downgrade back to honeycomb, I would not just flash a honeycomb ROM. I have found a few guides on how to downgrade back to Honeycomb from ICS. Is this correct?

Since you have cwm, It's as simple as going into recovery and flashing your desired custom rom.
Normal procedure (to avoid conflicts/problems) is to wipe and/or format before flashing a new rom.
A good tool to have is the superwipe lite script found in the Revolution HD thread. (I personally use that instead of the wipe option that is in CWM).
Oh...and you can also backup your current ROM and state by using the backup function in CWM BEFORE you wipe/format. Just in case you don't like the new rom and want to revert.
FYI...if you go ICS and want to restore your HC rom...a restore then a reflash of the HC Rom is needed.

Thanks for the reply!
Just to clarify, once I flash an ICS custom ROM and didn't like it, I can't just flash back to a HC custom rom or stock HC rom. Is this correct?

Yup. Even if you use the restore function...you need to flash that particular HC ROM over the restore. (Because the backup doesn't backup the kernel...so if you don't flash the HC rom...the ICS kernel is still there...and you won't be able to boot)

sorry to hijack the thread but my question is similar so i dun want to start a new one
I am currently on revolver 3.11 as well and thinking to update to a ICS custom rom
I am using the blade OC kernel at the moment. I just want to ask if the new rom comes with the ICS kernel or do I need to look for an ICS kernel to put it manually?
Also, I just want to check that Ti Backup does not back up downloaded data right?
Thanks a million

Everything is included when you flash one of the available ICS ROM.
There is no custom ICS kernel right now anyway as Asus have not released the kernel source.

[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!!!

you can try backing up your stuff with titanium backup and then doing a factory reset and start from scratch or you can look for the stock rom zip online and flash that...

1) Rom manager is not compatible with Atrix 2. I would not use it. Why do you need it anyway??
You can use Atrix Bootstrapper to go into CWM recovery . Rest can be done there. Or you can use Boot Menu Manager.
2)Of course! it will still be there! the backup is saved on your SD Card. So as long as you don't format your SD Card. It will be there.

Rom Manager does work with Atrix2. If you're on Stock ICS, you can install CWM on every boot, then flash the Bionic recovery through Rom Manager. That will allow you to use the 1 touch backup in RM, just hit backup rom and everything does what it's supposed to.
Here is the CWM on every boot for Stock ICS.

2)will the CWM recovery exist after flashing new rom or i need to install it again??
when i restore to stock fom JB, it means downgrading the firmware right??
so will there be a chance of bricking or is it same to restore anytime from any version??

No, your Recovery will be wiped after you flash a new rom, but you can install it again and restore your ROM.
But when restoring a rom, make sure you ARE ON THE ROM you are restoring.
E.g. If you flash JB and want Stock ICS back with your backup. First flash the Stock ICS from RSD and then restore your backup from CWM on it.
Or Vice-Versa.
@41rw4lk, Thanks for rectifying that. I did not bother with Rom Manager much.

I don't think any recovery exist after flashing a new rom. We have a locked bootloader, so we can't replace the stock recovery.img, all of our recoveries hijack the boot process to work. CM10 and PA I believe have a built in recovery, and that's about as close as you'll get to having a recovery exist after flashing a rom.
As far as restoring from JB, I believe you can downgrade to ICS, but you'll have to look at the JB thread to be certain. I'm on AT&T so I haven't had an opportunity to try JB (officially). CM10 is based on JB, but for our phone with the locked bootloader, it's more of a pseudo experience and is based on our ICS framework.
As for bricking, there is always a chance to brick, that's part of the mod game, but if you read and pay attention to what you have and what you're doing, you'll be alright.

UNLESS you have AT&T phone you should be just fine with ref lashing the ICS.
YES. there is a big problem if you are not on a ROM you are restoring.

You need to use the CWM on every boot setup, the Atrix2Bootstrap alone won't do.

Yes. I will say though, if you're on an AT&T branded phone with AT&T firmware, do NOT try to flash the new JB FXZ. It doesn't matter who your carrier is, it matters what firmware your phone is using. So, if you're on AT&T then you need to make sure that the things you flash are for AT&T, or else you will brick and that will be then end of that.

MIUI (had battery issues, but I think they got it all worked out)
there's a few, you'll just have to look. Most of the time, if something is not meant for AT&T, the devs will post in the description that it isn't compatible. If you want stock ICS back at anytime, you can do yourself a favor and make a backup of your stock ICS all setup the way you like it, so you can restore if needed. If all else fails, there is an Official ICS FXZ that will get you back to stock ICS.

You're killing me smalls. You're on ICS already, you're not downgrading anything, nor can you downgrade ie. Gingerbread. There is no Official JB for AT&T, so that's not an issue. CM10 is a JB based rom built on an ICS frame, (for our phone at least), and again, you're not downgrading.
To make a back up, boot in to CWM or whatever recovery you're using (not stock), and click backup. You might hit up the noob thread to get an idea of the terminology and basics for our device. Not trying to be rude, but you're running yourself in circles. You got to walk before you can run.

Switch between AOSP ROM and stock ROM?

Sorry if this is a dumb question, but it's not something I've tried before so I don't want to waste my time or hose something.
Basically, I'm trying to troubleshoot an issue and I want to know if it's my ROM or also happens w/ stock. I currently have the TWRP bootloader installed and Resurrection Remix (5.8.5). If I do a full ROM backup in TWRP, can I flash a stock-based ROM to test, then use TWRP to flash RR back?

Yep you can, just make sure you tick everything in the backup, and save it externally. Some flash methods might wipe the default TWRP backup location.
The bootloader and modem aren't included in the TWRP backup, but that'll only really matter if you're going between different android versions i.e. the nougat bootloader does not play nice with marshmallow. But it still runs.

Thanks. I do back up (from TWRP) to the external SD card so I've already got that covered.
So RR 5.8.5 is Android 7.1.2. If I download an Android 7.0 stock from from sammobile.com then I should be good, yes?
I believe those need to be flashed via ODIN and can't be flashed from TWRP, correct? Will flashing this ROM from ODIN obliterate TWRP or anything? Or should I be ok to boot recovery and restore RR back later?

if u flash stock,then twrp will be gone and u will return to ur stock recovery. Then if u want to restore ur old backup then u should root ur phone like it was from the beginning and install twrp manually and all.... anyway stock or stock based roms are better than aosp. Since the camera is much better than aosp.?

Hmm does this also apply to a stock-based custom ROM? That might be sufficient for my testing and I'd rather simplify things for myself.
All the stock-based ROMs I've seen so far appear to just be for the 930F but I assume there must be at least one out there that'd work with the 930W8
