I just want to let everyone know that it is possible to go back to ICS after updating to 4.1.2(9.16.6) I was rooted on 4.1.1 today, used ota root keeper to temp unroot and update to 4.1.2 and restore root. I just used Matts RazrHD utility 1.10 and went back to ICS 4.0.4 with no problems what so ever...
Im not sure why its stated that once you update to the newest release that you cannot go back, but its possible. So for everyone that wants to try out 4.1.2 and didnt want to be stuck, you can downgrade.
Hope this helps.
Also for everyone willing to try to downgrade please post results and type of phone you have, also the way you downgraded...
Device: Razr HD XT926 US Verizon non dev ed.
Original firmware 4.0.4(0.6.25)
Used RazrHD Utility 1.10 to downgrade
UPDATE: 3/21
I tried to downgrade again so I can post screen shots for everyone, and it did not work this time!!! Something must have changed/sync'd with my phone since the last time I downgraded that did not sync the first time. This has been a strange experience, but I would not have posted if I really did not have success the first time! It now gives errors, and I have tried everything I could imagine. My phone is not bricked and I am still rooted and have SS.
Preserving the option to downgrade to ICS is certainly important to me. Please, what phone do you have and from what country is your carrier (and thus, presumably, your version of stock ICS)?

XT926 Verizon US non dev edition, ICS 4.0.4 (0.6.25)
I will add it to the OP
OK ... I've got to know. Why did you leave 9.1.2 immediately after upgrading to it? The knowledge that downgrading back to 4.0.4 from 4.1.2 is certainly valuable, but knowing what prompted you to upgrade and then so quickly downgrade would be valuable to know as well. Did the upgrade go smoothly? Did the upgrade not function as expected?

No it was fine... I had some weird problems with data switching, from wifi to mobile... Sometimes it wouldn't switch back to mobile after turning off wifi but that was only a couple of times. I really just wanted to see if it was possible to downgrade and was willing to do it even though I could of been stuck without a phone. I also like to start fresh by downgrading and wiping/formatting my sd card every month or so. Im back on 4.1.1 now and will probably go to 4.1.2 soon on my stock slot either way.
What I did was Remote into a DROID RAZR HD owner's computer and flash the ICS boot.img file through fastboot. It failed pre-flash validation so I flashed to new boot.img back on there and considered it a case closed.
If it works to go back by using the Utility, thats great news. However I am not going to remove the warning until I get more than just one confirmation on it.
great news thx

I have JB 4.1.2 now and using Matt's tool, I can't seem to get it to downgrade. It will run through the process, then it will just boot up into 4.1.2 again. It gets a couple failed things along the way.
Because I'm still weighing whether to upgrade to 4.1.2 can you tell me -- did you get 4.1.2 OTA or did you flash a file? If you did a "manual" upgrade, how is the experience? Problems? Anything not working, or not working right?
Ota, everything went fine during the upgrade. Just make sure if you are rooted to activate stock slot and wipe all other slots. I also restored a backup of stock jb 4.1.1 I made a week ago with all apps updated and working. Then just booted up and temp unrooted with ota root keeper and accepted the ota. Restored root after it booted. Only thing that was different from other updates is that safe strap did not work afterwards so I had to uninstall and reinstall.
I don't see much improvement, but I just got back to 4.1.2 late last night after downgrading so that's not much time to tell if the improvements are there. I have not tried HDMI out yet,but will later today.
If anyone else tries to downgrade to stock 4.0.4 ICS from this latest update 4.1.2, please post what type of phone you have and if it worked for you. Any problems...???

You don't have to wipe your rom slots.just go back to stock slot take the ota and then reinstall safestrap recovery (not the program).your roms will still be there and functional.

Don't know how I've missed all this "stock slot, rom slots" business. I've rooted Android phones and tablets, installed custom ROMs, I've still a noob but learning. Does "slots" refer to all that sdcard0, sdcard1, usbdisk_1.0 business in /storage? I don't think I'd seen that on any of my devices until I got my Maxx HD with 4.1.1. Or are slots part of SafeStrap (I have that too but only because it was on my phone when I bought it on eBay)? Upgrading to 4.1.2 sounds like it goes smoothly if you do it right and is a pain if you don't. Sure would appreciate a little guidance that's specific to this set of tasks.
Well I feel like an idiot. I got the leaked 4.1.2 and now it's literally impossible to downgrade. I hadn't installed any bootloaders/roots/ or anything before doing this, so now that my phone is 4.1.2, it's basically stuck there.
I've tried hours and hours of everything. If anyone has any idea on how to bypass this I'd be grateful.

Did you do this procedure from stock? I tried from 100% stock. No unlocked bootloader, no root, nothing. I'm also using a Verizon Phone.

I downgraded successfully yesterday, so I reported my experience... I have no reason to lie, otherwise I would not have posted this in the first place!
I had some problems with my comp. and the usb/moto drivers on win7 today so I was trying to fix that before I could try again. I attempted to downgrade/restore to ICS again and this time it did not work! I cant see how it worked for me yesterday and today it wont? I was so happy when it worked, but something must have changed within the last day which is odd. I always upgrade and root the same way, and I have tried everything today to get it to downgrade with no luck. My phone still works so it is not bricked, and I apologize to everyone, like I said it did downgrade yesterday with the RazrHD utility 1.10 and there were no errors what so ever. Now after it asks you to hit any key once the phone comes back on in FB errors come right up. Some things seem to flash though, which is strange and basically it does a factory reset on the 4.1.2 . SS is still installed, its still rooted, and works fine. I can even restore back up of 4.1.1 stock jb(which I made last night after I downgraded to ICS and was upgrading again) on stock slot after wiping data/cache/dalvic and system and boot up to show 4.1.1 and then either try to downgrade, which fails, or take the ota and/or flash 4.1.2 manually but it fails also. Then I just reflash a back up of 4.1.2 and its fine IDK... I also flashed Vit 1.9.3 on stock slot fine, boots etc. but still wont let me downgrade. Then I tried uninstalling all updated apps on 4.1.2 and clearing data on all apps, still nothing.
So for some reason it let me successfully downgrade yesterday, but not anymore. So like many people have said do not try until there's a safe way, unless you are willing to risk bricking.
I am downloading the 4.1.2 fastboot files now.

I have friends in the Firmware Team
I have a galaxy s4 on sprint (SPH-L720). So about a week ago i reset the cache and data under Google services framework to get the update from Samsung. Well after quickly realizing how much i didnt enjoy 4.3 i wanted 4.2.2 back and began to look into flashing the old firmware back onto my phone. unfortunately i was stuck in the download mode or odin mode for a long time and after following many peoples different instructions on how to do it and not getting the proper results, i became frustrated. eventually in a desperate attempt to have a functional phone i tried rooting it, which got me out of odin mode. However, since i restarted the phone, i cannot turn on the wifi nor is there any sound. these were new problems among the same old problems that i had with 4.3 in the beginning which includes the video playback (which is non-existent). All i want to do is have my phone working like it did when i bought it with the android version of 4.2.2 with all the working features. any ideas?
I was going out of my mind too last night trying to go back to 4.2 but had no WiFi so I got fed up and just did the cyanogenmod installer video that qbking77 posted last week on YouTube which roots and installs cm10.2 all on its own at least it got me a fully functional phone for now until I get back home from work and try restoring again. Just thought I'd share a temp solution

If you accepted the ota too go to 4.3 I believe the issue you are experiencing is due to the Knox bootloader. Unfortunately I do not think there is any way to downgrade with Knox bootloader (for now). I'd try reflashing a fresh 4.3 rom and see if that fixes your issues.

Well I manged to restore stock 4.3 without a problem I guess it is that Knox deal

I reflashed with 4.3 and not only do i have wifi and sound back, but also i finally have video playback. it could be a more updated version of jellybean, either way, you, sir, are my hero. :highfive:
Hey guys you arent alone. There's hundreds of us....lol, try to make the best of it. Sac23 has a great rom. Check it out. There are also some other 4.3 based roms with great dev support available. It should help buy time till the devs can find a work around for the knox bootloader.
With the latest update I received from Verizon for my Razr M XT907 my phone has been using battery a lot faster than normal and running overall slower. I'm wondering if there is a way to downgrade to an earlier update version or just to the original build that was on the phone when it was released. My phone is not rooted or otherwise modded otherwise I would of just put on another rom or just did a total refresh of everything but it's stock so I'm kinda stuck. I've done resets, I've cleared the cache, I've checked the current root methods and none of them seem to work on this build (which is build 98.18.94.xt907 on verizon).
Really would appreciate even a point in the right direction for this phone as it's never been like this before the update, the battery was always good before lasting all day on a single charge and the lag with apps was never there before this update and I'm really getting bummed out over the phone now suddenly dropping in quality over an update.

Since your bootloader is locked, you can't downgrade. There are also no root methods for the current update. If you've already tried to clear caches and FDR, you might just need to use the stock firmware and flash it in RSD and start with a clean slate.
Wait a second. Let me get this straight. Locked bl =no downgrade?? All of a sudden there is lag and the radio is terrible! I was counting on being able to rsd back to the previous build.

The update before the one that patched the boot loader disabled downgrading with RSD. If you complain to Verizon, you might get lucky and get a factory unit with 4.1.1 installed, where you can then unlock and enjoy working stock.

I've had this phone almost 2 years now and never had an issue. Since I installed the OTA for 5.0.1 last week I've now had 3 random reboots. This is bringing back the nightmare of my G2X days. Anyone ideas?
Have you done a factory wipe? That's where I'd be starting. I never trust updates without a wipe. My sisters galaxy s 1 and 3 always got messed up every time she did an ota update.
I've never done many ota updates since I've always run custom roms.
Right now I'm running stock 5.0.1 on the n4 I just bought used and no issues at all but it got wiped as soon as I got it and updated it.
Sent from my Nexus 4 using XDA Free mobile app
I would wipe everything and reflash 5.0.1. I have been running it on the N4 since it came out and have not had a single issue.
If that does not work, get a logcat of the issue if you can.
Here's my situation. Last year I bought a Samsung Galaxy S4 unlocked AT&T (SGH-i337) phone from ebay. I am using Cricket. A few months back I tried updating it by going to the update area and checking for an update. I am on 4.2.2 and wanted to upgrade to KitKat. Well my phone tells me every single time it's up to date even though I know it's not. I decided to use Kies to see if I could update it using that instead. Kies tells me my firmware is also up to date. I gave up for a few months.
Now that Lollipop is out for my phone I tried once again doing the same things. Once again both ways say my phone is up to date. I looked through multiple forums to finally find a possible answer. My phone may have been rooted at some point and apparently if it was, it can't be upgraded. I read it needs flashed back to stock. I looked at a nice long guide on here on how to flash back to stock and saw you need to know which boot loader you have?
Please help me guys. I'm assuming my phone was rooted and have never rooted myself but I want to flash to stock so that I can upgrade to Lollipop. Any help would be greatly appreciated!

I flashed it successfully and am now on 4.4.2 however OTA and Kies both still say my device is up to date. At this point it doesn't look like I will ever be able to update using these two ways. I looked around trying to find a Lollipop flash but didn't know if any of them were safe. Can anybody point me toward a safe stock flash for Lollipop, or does this not exist yet?
