Just a simple doubt.
Is it possible to downgrade from 4.4.2 to 2.3.6 or 4.1.2?
I am currently on SlimKAT 4.4.2 and it sucks. The battery life is hell. Also the camera doesn't work.
Can anyone tell me any way to downgrade?
The reason I wanna do this is that I only wanna use it as a backup phone.
And if possible, please guide me though the process.... Thanks....

I successfully upgraded my x10 mini to Android 1.6 and I'm not happy with it. Does anybody can help me to downgrade to 1.6 firmware version?
Why would you want to downgrade it? it's not like they removed features, I thought it feels more responsive and generally has more features.
Im not really sure its possible to downgrade other than flashing an old ROM, but im not 100% sure
It is possible.. Look at this thread for the 1.6 image http://forum.xda-developers.com/showthread.php?t=826469
The flash tool are in the same section on the forum..

We all know about the bluetooth improvement, but I can't pair my phone with the hands-free system in my car anymore.

Hi akim14,

I actually bought one but received it and could not hear any sound when someone called in.
I sent the phone back to China and I am waiting for a new unit.
I have this phone but cannot find anything on how to root it, anyone know how ?
Or if there is a update as it is running 4.1.2 ?
Thanks in advance

I haven't received my replacement phone yet, so I couldn't try nothing.
Any upare in this matter will be welcome...
I have now flashed 4.2.1 which is working a lot better than 4.1.2. Even the GPS is now working properly.
Still need root though.

yes I would also be very interested, I just got my Newman nm890 android 4.1.2 and it has difficulty picking up a cell signal where my other cell phone gets a couple of bars. I am having difficulty with rooting it. I have been waiting for the 4.2 to be available but different from the sales ad, it does not seem to be readily coming. The previous reovery.img with the QR is it 4.1.2 or 4.2.1. It looks like the nm890 is popular.
4.2.1

Where did you download the 4.2.1 firmware? My 4.1.2 is somewhat lagging.

I've been trying for the last 2 days to update from NAB to NC5. But I can't seem to get it. Its already rooted and I really want to try Sacs Custom v4, but I can't seem to figure a way to do it or thread that helps me fix the problem I'm having. If you need more info I'll be more than happy to give it, I just don't really know what to tell you guys to get this started. Can someone please help me?:angel:

What I did was use the one click restore to NAB. Then the OTA update to NC5.
You will have to root ad such again.

Ok, does it have to be a official NAB, and if you don't mind, can you link the thread that you found the one click NAB on? I'd really appreciate it

You sir, are a here ?? thank you so much
Sorry I know you guys get common stuff like this a lot, and as such I searched for my issue but everything I found lead me to a dead end.
I'm currently using VZW Galaxy S4 (SCH-i545) with build VRUDMI1 and android 4.2.2
I had disabled OTA updates by using a guide about a year ago. I'm needing to unroot my phone and put it back to stock so I can get OTA and move on to 4.4 (I don't know enough about custom roms and flashing to do it without OTA).
From what I read, I need to use odin to flash a tar file while in download mode. Problem is, I don't know which file to get. I've looked at some guides but I can't find a working link for an SCH-545 VRUDMI1 with 4.2.2
Any help would be appreciated and thanks for your time.

Thank you, I did discover that very thread, but the build number doesn't match mine. I wasn't sure if that made any difference and out of fear of bricking my phone, I posted this to make sure. So even though the build isn't what mind presently says, it should be ok?

Yea, this will update and unroot all in one. Like the post said, if that update doesn't work, then grab the NC2 one. It would be best to factory reset as well.
I have the note edge, still on kit Kat, it's rooted. But it's got a stock rom. I was thinking about upgrading to lollipop, but read I'd have to unroot kitkat, install the official lollipop, then root lollipop?
Are there step by step instructions, or maybe even an easier way out there?
I miss the days when we could just flash radio updates and any rom we wanted without doing anything else. Ha.

Thanks but that thread is for T-mobile?
You have to Odin back to stock firmware. .. Let the OTA take place then re-root ..
Werd.

I assume that this hasn't changed at all?
OK2 isn't rooted yet, so flash the OG1 stock rom for lollipop and root that one. Don't take the OTA though cause you'll lose root.

I'm sure I do somewhere. But it isn't a fresh install. It has my hacks and my own settings and my everything including any personal info they it stores? I. E. Google wallet info and lte encryption keys.
Thats no problem if you're still on KitKat make a new backup excluding the data and cache partitions, hopefully thas not too much for a friendly request lol
