[INFO] What you need to know about ICS and your Atrix 2

I have been seeing MANY threads lately involving questions such as, "How do I get on ICS?", "Should I update to ICS?", "I think I am bricked, how can I fix this?", and "How do I FXZ back to GB?" So I am creating this thread as an information only thread to answer these questions and more with links to proper threads that have already been posted for your benefit. Unless otherwise noted by the OP's or myself the following threads apply to the AT&T MB865. So without further ado....
What you need to know about ICS and your Atrix 2
The first link you need to look at is the Noob thread. I am going to be using terms like "Bootloader", "Soft-Brick", "Hard-Brick", "FXZ", "Fastboot", "OTA", and the like and user/developer JRW28 has posted a FANTASTIC thread to help you familiarize yourself with certain Android terminologies and certain HOWTO's that will help you understand and accomplish much of what I am going to be referring to. So with the Atrix 2, if you are confused with something. START WITH THE NOOB THREAD. Find it here: JRW28's NOOB Thread
Done? Well read it AGAIN.
Oh, what's that? You read it twice and memorized it? Okay, moving on....
The first question that needs to be answered is:
SHOULD I UPDATE TO ICS?
Well, we have all been waiting for ICS to come out, and it has officially been running on the Atrix 2 for a while via a find through Cheesecake. The initial leak is NOT the final OTA that is still trickling out. You need to first understand that. Is ICS better than GB? Of course it is. No one will argue that here, but what we are tackling is, should you upgrade to it?
When it comes to XDA, we are always looking for ways to improve our phones. That's why we're all here right? This is a DEVELOPERS site. With developing comes trials, and with trials comes ERRORS. Now when it comes to the Atrix 2 (A2 from here on) we have a locked bootloader. This means that recovering from developing, and/or modding errors is not as easy as recovering from errors and mistakes with phones that have unlocked bootloaders. Normally, on phones with unlocked bootloaders, it is easy enough to jump into Clockwork Recovery and restore a previously saved nandroid backup, because with unlocked phones the modified recovery REPLACES the original. Poof. Back to normal.
On locked down phones such as the A2, we have to depend on either a bootstrap recovery or the like to make up for the lack of our locked phones. Do we have recoveries? Sure, but they DO NOT replace the original stock recovery and therefore we depend on things such as Bootmenu and Safestrap to makeup for this. While this works it is definitely not ideal. So what happens when the recovery get's borked, ROM goes belly up, or your phone is stuck at the splash screen and won't boot into recovery?
Well this is where the ICS upgrade question comes into play. This phones DEPENDS on FXZ's (see noob thread for more info). If the above scenario(s) happen then we depend on being able to jump into Fastboot (FB from here on) and reflash our phone back to stock. With Gingerbread this was easy enough as we had an FXZ for GB.
With ICS, ONLY THE FIRST LEAK IS ABLE TO REFLASH BACK TO GB! WE HAVE NO WAY TO REFLASH BACK TO GB WITH THE LATEST LEAKS AND THE SOON TO BE OTA UPDATE!!!!!!
Only when we find an ICS FXZ will this be possible!
Now I can hear it now. Some might say at this point, "Well once I'm on ICS, I won't want to go back to Gingerbread." The point, my friend, is not WANTING to go back to GB, it is needing a way to fix your phone. I myself have a paperweight for an A2 for EXACTLY this reason. I was running the latest of the leaks (NOT the first, which we can go back with). I had made a couple of mods, as bootmenu was working for it, and I made a backup. Well, I flashed a mod, rebooted and BOOM. Bootloop. No biggie, I thought, I will just restore my backup. But apparently I had deleted my backup. I tried, with the help of Devs (whom will be named later) to FXZ back and quickly found that this was impossible to do at this point. Now I have a phone that is able to boot in FB, with no way of restoring it. Fastboot does us no good without a proper working FXZ to flash.
So upgrading to ICS at this point, is fine, but be warned, if you make just the littlest boo boo, you might have a paperweight on your hands. Myself, many of the other Senior Members, and many of the A2 developers are recommending to run the first leak, because it is the most stable and dependable as far as getting yourself out of a jam. Also, many of the the more stable leaks have been baked into the current ICS ROMS we have. Now once you are on the first leak, you will have no problems flashing these ROMS with the more stable versions on them, but you MUST be on the first leak beforehand!!!!! As always read carefully the install instructions from the developer and if you're unsure, ask a question in the ROM's thread before flashing!!!!
UDPATE 9/20/12 It seems as though Moto and AT&T are now releasing OTA updates to our leak! Remember the reasons as to why we are advising against them! IF YOU GET A MESSAGE TO UPDATE WHILE ON THE FIRST LEAK, COMPARE THE FIRMWARE INFO WITH THOSE LISTED IN THE THREAD BELOW BEFORE UPDATING!!!!!
THREAD WITH INFO ON OTHER ICS LEAKS AND WHY WE ARE ADVISING AGAINST THEM AT THIS POINT. Originally posted by alteredlikeness
The rest of this will mainly be references to threads as most questions have already been answered in other threads as I just felt we needed a place to consolidate all the info out there on this. Here goes...
In the following theads, PLEASE thank the OP's!
HOW DO I UPDATE TO ICS?
Other than the OTA method that has been trickling out at this point, I am ONLY going to refer you to the thread to get you onto the initial leak. Because at this point many of us see this is as the safest leak. As you have a way out. Because we want to do what is best for you and YOUR phone.
NOTE: The rest of these threads (unless otherwise specified) refer ONLY to the first leak, and to NOTHING ELSE!!!!
How to get your phone on ICS, and how to root it: Originally posted by Jimbridgman
Ok so now that you are comfortably running ICS and rooted.....
HOW DO I INSTALL A RECOVERY?
We currently have two recoveries for the first ICS leak. Both are very stable and work well, but are slightly different. Read each of the following threads for how to install and the differences between them.
BOOTMENU RECOVERY Originally posted and developed by lukensteinz and Whirleyes
SAFESTRAP RECOVERY Originally developed and posted by Recognized Developer Hashcode
And FOR PETE'S SAKE, now that you have a slick recovery working MAKE A BACKUP!. And then copy it and put one on your desktop!!!!
I MADE A MISTAKE, HOW DO I FXZ BACK?
You are ONLY going to be doing this if you somehow messed up a MOD, didn't make a backup, and now you are in a bootloop. REMEMBER, THIS IS ONLY FOR THE FIRST LEAK. I AM NOT RESPONSIBLE IF YOU DID NOT READ THROUGH FAR ENOUGH AND BRICK YOUR PHONE. If you managed to try and FXZ back while NOT on the first leak, or your phone won't turn on or go into FB, then, well sorry mate, but you are HARD-BRICKED. But if you are on the first leak then the following should work.
HOW TO FXZ BACK TO GINGERBREAD FROM THE FIRST ICS LEAK Originally posted and developed by Jimbridgman
ROMS TO INSTALL BASED ON THE FIRST LEAK
NOTE: You must be on the first ICS leak in aforementioned post to properly install the following ROMS, unless otherwise noted by the devs! And as always read CAREFULLY the installation procedure as laid out by the developer!!!
ScV7 - ICSupercharged Originally developed and posted by rdavisct
De-odexed and De-bloated basic ROM Originally developed and posted by timmytim
ROMS THAT ARE STILL A WIP:
MIUI PORT FOR A2 V4 2.8.17 Originally developed and posted by rdavisct
CYANOGENMOD 10 - JELLYBEAN Originally posted and ported by wanggjghost with continued help and fixes by rdavisct and Jimbridgman
In closing, hopefully this will answer all your who's, what's, and how's of ICS on the A2. Please DO NOT post questions regarding the threads themselves here. Post those in the appropriate posted thread, as this is what this is for. TO KEEP THINGS ORGANIZED!!!!!
If I need to update the OP, or have left something out. Feel free to post it here.
Enjoy ICS! And remember! ALWAYS MAKE A BACKUP!!!!!!!
Special thanks to the following: Jimbridgman, rdavisct, alteredlikeness, Apex_Strider, DX2Trip, Mtnlion and any others I left out.

Consider your bootloader a prison warden. Nothing happens unless the bootloader says so. Pretty much plain and simple really. It's the partition on your device, which initiates first. And it checks to make sure the OS is a legitimate one. Ultimate security. If it thinks everything is in order (after communicating with the kernel), it boots the OS. This is the security most devs have to work at, to allow installation of custom recovery and roms.
There are 2 types of "bricks". A hard and soft brick. Soft bricks you can usually recover from. A hard brick, well, it's not impossible, but difficult. Typically with a hard brick, your device is basically dead. No response, or stuck at the logo screen forever more. forever more. forever more...... Edgar Allen Poe. You always want to avoid a hard brick. In essence, your device becomes nothing more than a ....brick.
Fastboot, is a part of the Android SDK. It allows some types of files to be "flashed" to certain partitions of the device, without a need for a custom recovery. For example a boot.img (kernel for easier terms), a recovery image, and a few other image files. Of course depending on the Bootloader, depends on what fastboot capability you have.
Some devices, Devs have been able to re-write the Bootloader to enable fastboot when it wasn't there from the factory. See Iconia A500. By virtue of patching, and re-writing, the bootloader was stripped of all security and features added. But you can't do this with all bootloaders.
Hope this explained.

Hey Bro I have an Ics ota now. Will that unroot the phone? If yes how do I root it back? And is there gonna b any problem if I update with root?
Sent from my stock rooted Atrix2!

If you are stock 2.3.6 rooted, then yes you will lose root.
As far as rooting ICS goes you should be able to root it with Jim's script from the thread I posted in the OP.

Just a question out of the discussion but not of the thread. Why does ATT gets last the ICS OTA?? I see Cambodia and India got it already while ATT phones are still on leaks!!! Isnt this weird considering that ATT is the biggest Moto fan?!

how is the battery life on ics? better or less than GB???

Yes there is a "Root checker" however, it will not hinder your installation, but as far as long term issues? We have no idea as to what Motorola is going to do with this.

its obvious for voiding our warranty

If you're rooting/modding/theming/tweaking/overclocking/underclocking/changing voltages/editing build.prop/etc./etc./etc. haven't you already thrown caution to the wind in regards to your warranty?
If you are concerned about it, they (Apple) just released a new iToy, so all you have to do is pull it out of the box and use it.. as is... unless you 'jailbreak it', in which case, warranty worries wander back into the equation, right?

once started how do i stop the ota download

You don't. You can download it, and then NOT install it if you like. Once downloaded it will be in your cache folder.

If update failed because of checksum error, downloading again won't be of help. Most likely you have changed a file that the update is trying to patch. Better you go back to stock 2.3.6 and then apply OTA.

Same happened with me as to the person above. Downloaded the update. I but it says update failed? Do I have to unroot or something?

[Q] dont like ics, want gingerbread back

NOOB HERE
i'm from india and using mb865.
i updated my phone from gingerbread to ics a week back. But i'm hating it(interface) and want to go back to gingerbread as i loved it then..
but before updating moto clearly stated that we CANNOT go back to gingerbread...please help i want my earler phone back!

You can't go back to gingerbread from the official OTA to ICS. Sorry mate. You're stuck.

Yes you can
You can indeed revert from ics to gingerbread. I have done it and it works.
I hated ics mainly because of the rotten battery back up...On gingerbread i used to get about 3hrs for every 10% drop in battery..but in ics it used to drop by 10% every 1.5 hours. Hated that.. Plus there are hardly any benefits of ics on the atrix if you installed go launcher and other apps..plus if you can debloat it using titanium, it becomes even smoother than ics,.
This is how you do it
Install RSD lite 5.6 (search in google)
Download the motorola drivers and instal it
Switch off your phone
switch your phone into the bootloader mode by pressing both the volume buttons and then the power button....then choose fastboot ap
open RSD lite and browse to the original untouched GB rom
You can download the rom from hxxp://sbf.droid-developers.org/edison/list.php download the asian retail searet 28.37
plug in the phone through usb.. wait till all the drivers are loaded
then click start>>uncompress and start flashing
the flashing will take about 20 min and the atrix screen will switch on and off repeatedly...
DONT disconnect the phone until it says "finished" in the RSD lite
and you are back in GB
Mae sure that you battery is atleast 50% charged before starting and that the computer doesnt go into sleep during the flash
I have done this about 2 times without any issues but i will not be responsible for any bricks
happy flashing

The real question here is whether you (spunxhoe) were on a leaked version of ICS or the official OTA release of ICS. We're all aware -or should be- that the only known way to FXZ back to GB is if the user is on a leaked version of ICS, not the official. If you were, in fact, on the official OTA ICS and flashed back to GB, please provide more tangible proof other than 'yeah, you can -I've done it twice'. If you have had success coming from OFFICIAL OTA ICS to GB, then you need to give us some legitimate evidence. As it stands now, we all have been advising users NOT to flash back to GB if on any official releases of ICS due to the certainty of soft bricking...

Get your facts right
Right...and whats the proof you require?
These are all the things that have done...stock GB rom to ICS leak..then back to stock GB..then upgraded OTA ICS..and then back to stock GB rom..The GB bootloader has a A.68 version.. the ICS bootloader was A.72 or 73..cant remember..I HAVE FLASHED back to GB from OTA ICS using the method described... Apparently you have got your facts mixed up...THE AT&T ICS ROM leaks have caused bricks..not the SEARET ones.. MOD EDIT.... NO PROFANITY.
---------- Post added at 10:22 PM ---------- Previous post was at 10:10 PM ----------
Oh yeah.. i have had three soft bricks..thats only cos i tried the clockwork recovery mod specifically modified for atrix 2.. it did work at times but it also caused the soft bricks and had to reflash the roms..

I wonder what's the "in principle" difference between a leak and OTA. I flashed the ICS cheesecake leak which turned out to be the SAME as the OTA that was pushed out later.

Truce
[MOD EDIT...................
Truce....maybe i was out of line there...but couldnt let it go when something that i had done myself was shot down without a buzz..
I HAVE FLASHED BACK FROM THE OFFICIAL OTA ICS TO GB STOCK ON MB865 SEARET USING RSD LITE..
But i cant stress it enough...the AT& T leaks have got bricks..but not the searet....take my word for it..as far as you can throw me atleast....
and if proof is required lemme know..i will give em as far as i can make out there is no way of proving a version 18 rom to be a leak or OTA..

Fair enough. And, for the record, if you thought I was in any way slighting your statements from your own experience regarding the above conversation(s), then I apologize. Perhaps, it might bode well for you, and others on SEARET ICS for you to post a thread with some definite instructions/screenshots/etc. with the abilities you (on SEARET/MEARET) have to flash back to GB. You would find yourself much more well received in doing something such as that...

In fact, there is. Somebody had posted the OTA file on mediashare. The MD5 checksum was the same as the version 18 leak. So the OTA and leak are identical...byte for byte.
Anyway, whether they are identical is not important. If someone is speaking of difference between a leak and OTA, there must be some difference between them other than the title! No?

I think the point would be that if this does not work the phone is a paper weight..... So working or not someone who joined this week and has a post count under 10 makes proof that much more needed..... In the past there have been quite a few people that have made claims that fell short and bricked quite a few phones and like that they were gone..... In the best intrust of the OP wait for a dev or other with the proof of concept before you attempt anything..... If you value your device ICS is better than a brick!!!!!

I would think the risk involved of FXZ'ing back to GB from an official ICS is just not worth it, since I think INDIA Moto's have NO WARRANTY.
However, what is the probability of rooting, installing bootmenu manager, and from there, doing a restore, then flashing a GB rom without the stock recovery?
I have not read anything on this as I think most people want ICS and I have not seen anyone try. I think this could be a way back to GB, but I am looking for someone who has tried this, I AM NOT ASKING SOMEONE TO RISK A BRICK TO FIND OUT, just wondering has anyone already tried it and what happened???
Another possibility: There are launchers themed for ICS for GB, are there any GB themed launchers for ICS for the nostalgic fellows like this guy??
But, I guess if he is looking for webtop, then like me he is waiting for JIM's ICS webtop project.

Hi,
Indian Moto A2's come with 1 year warranty.
Please see the link in my post above. People have flashed back from ICS to GB and lived to tell the tale.

Will get you the screen grabs for the flash back
guess no one has faith in humanity afterall...gimme some time and i will get the required screen grabs...it aint easy to update the OTA ICS and then reflash GB...and this is when i had completely customised and debloated my GB rom the way i wanted..
Still for the greater good....:angel:

If you removed or changed any "stock" apps and can't ota to ICS please read

I see a lot of people in here asking for stock apps that they removed instead of froze, and have also seen people having issues with the OTA not working, due to trying to save root through an OTA, or having bootstrap/bootmenu installed.
Look guys this has been covered a billion times in here, since the 2.3.6 update was out in Jan.
Please use the fxz back to 2.3.5 or 2.3.6 if you were on 2.3.6, or if you are on leak 1 then use my script in the dev section, then do the ota with out installing ANY apps at all.
This is really the safest easiest way. If you are on leak 2, then that is the exact same as the OTA, so no need to apply the OTA, you will gain nothing and you already can not fxz back, so..

Oh didn't realize that leak 2 was the ota. Awesome, I'll stop spamming update checks now. Thanks Jim!

will FXZ back to 2.3.6 before applying the update.

I think you had mentioned in one of your posts that when we FXZ back to stock 2.3.6, do not login to google and then try OTA.
It will go through? wont get up to date message. Am I correct

Confused about OTA update

Ok, so I got a message for the OTA update today (ver 67.21.125.en.US). Now, I see all these threads that say don't apply the OTA because you can't flash back. But they seem to be talking about if you are already IN ICS. I am running a custom mod version of the supercharged 2.3.6 rom.
Is this the official ICS update? Should I flash all the way back to stock and then just do the OTA's? Will that process make it so I will not be able to FXZ back?
Or Should I follow the instructions in this thread? --> http://forum.xda-developers.com/showthread.php?t=1779968
The only question I have about the above linked thread is I am not sure if that info is out of date regarding this update I just saw today. If the OTA that came up today is nothing new (and it just took forever for me to see it for whatever reason) and everything in that thread still applies, then I will probably go that route. However if this is a new/different update, then I dont know what to do.

All of your questions have been answered numerous times in numerous threads over the past week.
I suggest to read - A LOT - then, make the choice whether to go on the official ICS (your phone must be in stock 2.3.6 GB condition), or non-official leak#1 which you linked (which yes, we are still able to downgrade with leak#1 ONLY).
If you are going to go on custom roms in the end, then it really doesn't matter... and in my opinion, I'd prefer to have the option to FXZ if I'm in trouble - so I'm personally sticking with leak#1 as a base firmware - at least until we get an FXZ package for the official at&t 4.0.4 ICS.

Ok, I suppose I should have phrased it better, but my main question/concern was whether I was seeing a newer update than what all those threads were talking about. It seems as though I am not.

[Q] JB back to ICS, still possible to use NvFlash?

I recently purchased my TF700- I wasn't aware of the fact that unlocking the boot loader would void your warranty, and that there was a slightly more complicated process for prepping the TF700 for flashing roms and kernels compared to previous android devices. (This is my first tablet, so I don't know if this is normal for tablets though!) Plus the fact that I need to be on ICS to do everything initially.
And just a BTW, this is comparing it to my experiences w/ the G1, Epic 4G, GS2, and the GS3- where I never actually had to deal with unlocking the boot-loader directly/or having the risk of ruining my warranty.
So basically what happened was that I read through the forums and learned that unlocking the bootloader would void your warranty- and being that it is always risky business + the fact this tablet is a lot more expensive than a phone- I decided I wasn't going to be rooting/flashing roms and kernels and etc, on my TF700. I didn't want the risk of bricking something I just paid $600 bucks for. So I took the OTA update to Jellybean.
With further research though, I found out about NvFlash, and then it would make my tablet brickproof. And that immediately sparked my interest! I read though, that it does not work with the .30 firmware though.
This is where I got a bit confused- I know I can downgrade to ICS (the .30 v tho) and then unlock/root/then flash stuff.
BUT, by me taking the OTA update to 4.1.1 JB, did I **** up my ability to use NvFlash? Cause I really want too unlock my phone and flash roms, but I'm just really scared of bricking my device.
If anyone could help with what my plan of action should be, it would be much appreciated, thanks!

Can't be done unfortunately, you need .26 firmware for nvflash. At the moment you're out of luck :/

****! Well just my luck :/.
I was going to send in my TF700 back in anyways for a replacement since the screen was popping out in the corner, so I guess I'll wait till then!
Thanks for the response!

Just out of curiosity, why doesn't downgrading back to an ICS rom do the trick? Is there something that gets left behind by Asus's JB rom that doesn't get downgraded when you go back to Asus's ICS rom?
Sorry to revive an old thread but I couldn't find a pertinent new thread about this.
Thanks!

You need a bootloader that does not check signatures to install the hacked bootloader. You cannot downgrade to such a bootloader, because all later ones do check signatures, and the unsigned ones are rejected.

Well, Asus had patched the security hole with .26 ICS firmware. They updated the next version of ICS which is .30 and this blocked the exploide. The signature (key) from the ICS .30 is no longer the same as ICS .26. So if you tried to downgrade to .26, you're going to see signature mismatch and it will failed. The signature on ICS .30 and all of the JB are the same, so you can upgrade or downgrade from 30 and up....Here is where the story ended!!

Ah, OK that makes sense. Thanks for the explanation!

Downgrade from JellyBean to ICS
Hi,
I am very new hear and not sure how to start a new thread. I just purchased the Asus TF700t because it was supposed to have ICS, but I found it has JellyBean. Is there a way to downgrade it to ICS?
Thank you.

You need to look around a bit.
I attempted an answer for you in another thread that you had replied in.
