I'm really wanting to roll back to Android 11. Two months ago I was able to roll back to Android 11 from 12 using Odin, but it seems the latest update or two has completely locked the bootloader from earlier versions..
As someone more than familiar and comfortable with getting root, unlocking bootloader, changing roms and using Odin on all my previous galaxy phones it seems the S21 is a black spot for that kind of talk. Is there any way to downgrade?
hello, for downgrading your phone's operating system version you need to know, what the binary version your phone has (now it is usually 5) and you have to search for a stock rom version with android 11 with the same binary. You can find it on sites like samfw and so one

Hi, I'm a noob seeking advice. I rooted my phone a few weeks back just because I could, but haven't really done much with it since. I haven't upgraded from 2.2.1 yet -half because I've been busy and half because I'm shy about bugs.
My question is: since LG claims it's going to release the official upgrade this month, what are the advantages of official upgrade versus unofficial? It seems like every unofficial one has bugs still, so I'd be tempted to go back to official. Also, since I've already rooted it, I'm under the impression that kills official updates. If I want to go back to the official version, would I have to unroot it first or is there a way to just allow the official update to go through?

About the 2.3 official update, everyone is waiting for that, since 2.3 unoficial Roms have bugs and unimplemented features. For example, I love the CyanogenMod rom but I had to gave up on it since the the bluetooth is not working for auriculars and for the bluetooth system on my car. The 2.3 official update will solve all the problems for these current unoficial Roms, so if you really need a fully working Rom, better not go for those 2.3 Roms available.
You should not upgrade to 2.2.1 (or 2.2.2) using the regular LG update method. That will "unroot" your phone. There are 2.2.1 and 2.2.2 official unrooted Roms (just google for that, you will find them pretty easy). In that case you won't use the KDZ method but the safer Android Recovery method (avoid using the KDZ!! it's the easiest way to kill your phone!!).
So... if you just want to "unroot" your phone, you can always get the official update back in your phone, by using the KDZ method. KDZ reflashes your phone, and that's why the risk is higher than using the Android Recovery method which one wipes out some things like /system/*
mix em both and they will shine...I hope LG's release sky rocket's mik CM7 rom and then i will permanently switch to CM...they simply rock..

That's exactly why I haven't gone for it yet. That and I've heard the GPS is still buggy.

I already had the official 2.2.1 before I rooted with GingerBreak, and haven't changed from that. I thought that rooting the phone would automatically block the OTA updates. Is there a way to simply allow the OTA 2.3 update when it comes?
As for kdz versus Android Recovery, everything I've seen around the web for returning to stock says to flash using kdz. Are you talking about using home+vol down+power?
hi..
i want to know if that it is possible to downgrade any android device without problem ..??
thank you...!!!
I suppose that any android device could be theoretically downgraded to a previous software version. For some devices you can find even s stock Rom, based on an older version of android, so that everything would very likely work... But, if your phone run android 2.3.7 and no stock Rom based on 2.3.3 exists, it won't be easy to find a custom rom based on older software, apart from the need of rooting the phone.
So you would have to build it from source (not easy at all) or trying a port.
In any case, most developers work to get the benefits of the latest software and I think that nobody works to go back to outdated software.
Most of the time you will only be able to downgrade to the first version of android that was shipped with the device (As it can be hard to back port drivers etc) for example my Note was shipped with 2.3.3 so I could not downgrade to anything lower that that
Yes, I believe it's possible to downgrade your device. You just have to flash some special ROM (with older Android version).
My CM-105 is completely rooted by Kingo Software and I have been to countless threads that go back far as of 2014. Many of the links are no longer provided or current and I really need to get a different Android OS than 4.2.2. The original phone provider AT&T and of course Samsung no longer continues support for this device to receive the update / upgrade.
How would I go about updating the OS to KitKat or Lolipop and where would I find the .ISO or .IMG?
Anyone know of a way to downgrade my Verizon Ellipsis 8 Tablet from its current android version of 5.1.1 to its old version of 4.2.2?
Any help would be much appreciated.
did someone made it ?
I understand you, I also want to roll back, in the end I got stuck in bootloader mode ... (I wanted to install TWRP, in the end, as I understand it, I killed the tablet, _,) In order to roll back, you need to flash the tablet, but for this you first need to find the firmware with the desired your version
Hello, I have a s9 plus from the att company, which is bought in usa, the official att page has never been updated to me, they say they are on android 9 but I only have the android that came from the factory.
Searching there from other XDA forums I found that through recovery I could update by update.zip files that if they work out of firmware. Science from there I have android 9 beta 4 and I really want to get the beta or upgrade to one that is not beta either android 8 or 9, without ODIN, my phone can't flash and I can't see the option of oem unlock. Odin doesn't work for me.
Anyone know where to get the update.zip of the new versions of android 9? .. I need a lot of help this had not happened to me with my previous phones ...
