I have a Galaxy Note 2 (GT-N7105) rooted on CM 10.1 on 4.2.2. Prior to this I was on stock 4.1.1. How would I go about unrooting and going back to stock 4.1.1. Is this even possible? Also if/when back on official firmware, would I be able to then update to 4.1.2 via the Samsung update feature?

HTC Incredible :: How To Downgrade To 2.1 From 2.2

Sep 11, 2010

I saw a similar thread, but didn't see the answer I was looking for. I did the OTA upgrade to 2.2 last week. Having some problems, so I thought I might roll it back to 2.1. Is doing the factory reset the same as downgrading to 2.1? OR is there some other way to downgrade? If so, could somebody provide step by step instructions?

HTC Incredible :: How To Downgrade From 2.2 To Get Radio 2.x?

Aug 9, 2010

I rooted my Incredible, and now I have it running the Froyo leak. Unfortunately, I didn't install radio 2.x before doing this, so my camcorder doesn't function properly. Is there a way to downgrade from Froyo to 2.1, install radio 2.x, then reinstall Froyo?

HTC Incredible :: How To Downgrade To Official 2.2

Sep 20, 2010

There have already been several requests for information on how to downgrade back to the official 2.2. The following process will remove root. Whether you need to return a phone or you just want to clean the slate and go back to stock, here is how to get there:

Note: Your SD card MUST be formatted to FAT32 before proceeding. The file will not be recognized otherwise. If you have yet to format, remember that formatting wipes the card. Be sure to copy/move your SD contents to a safe place (PC desktop) and replace after the formatting process. I will not go into the procedure in this thread as it is easily found with a Google search.

1.) Need to return a phone and currently have S-Off? (aka Unrevoked Forever) If so, please visit public:forever [RootWiki] where you can download the latest S-On tool and the process to load to your phone. If you want to keep S-Off and just return to the official 2.2, skip to step 2.

2.) Download the 2.2 PB31IMG.zip (extracted from the official 2.2 RUU)

Mirror 1 (Credit and thanks to Doug Piston for hosting)
Mirror 2

Note the file size (172 MB) and the MD5 (31BB1611A0FA8197D447C0438426717E) to ensure a successful download and file integrity. If you have questions about how to verify MD5, please see post #2 of this thread.

3.) Attach phone to PC with USB debugging on and in disk drive mode.

4.) Access the SD storage and drag the PB31IMG.zip from the desktop onto the root of the SD card (any open area, do not place into a folder).

5.) Swipe down notification bar on phone and change to charge only.

6.) Unplug phone from PC and turn off phone.

7.) Hold volume down while pressing power button to enter hboot.

8.) PB31IMG.zip should be automatically recognized in hboot. Press volume up to continue with update. Do NOT interrupt.

9.) When finished, reboot to stock 2.2 and verify the following information at Menu > Settings > About Phone:

Android Version: 2.2
Baseband Version: 2.15.00.07.28
Software Number: 3.26.605.1

10.) Remove the PB31IMG.zip from the SD card to avoid an inadvertant reload in the future. You are now unrooted and on stock 2.2

Also adding the RUU option for those that are interested. Thanks again to Doug for the upload/host. For those new to RUU, download to a PC and run from there:

HTC Incredible :: A Smooth Downgrade, So I Can Upgrade

Aug 31, 2010

I tired installing the 2.2 update, but as many of us have seen problems have been occuring. I updated my sisters radio to the version that changed the start up screen. I didn't root the phone or apply any other update except for that one. Obviously I need to downgrade what I did to the stock. I downloaded SDK and will attempt to follow this:

HTC Incredible :: Downgrade HBOOT Without Clockworkmod?

Sep 3, 2010

I had 2.1 rooted with S-OFF
I wasn't able to update to 2.2 via OTA so I found an update.zip
I attempted to load the update.zip but it failed
Using [VIDEO] HowTo UnRoot Incredible by downgrading I downgraded to stock 2.1 but for some stupid reason I also disabled unrevoked forever and went to S-ON
I then applied the May OTA update Getting your phone ready for the FroYo update.zip!
Following that I applied the 2.2 update.zip

Here are the versions I'm on:
HBOOT-0.92.0000
RADIO-2.15.00.07.28

Now I'm trying to apply unrevoked3 and it fails
I found 2.1 stock to 2.2 rooted (with links to files)
I tried to downgrade to stock again and I now get this error:
Main Version is older!
Update Fail!
Do you want to reboot the device?

From what I understand I'm unable to downgrade to stock due to having an updated HBOOT
I've found instructions on how to downgrade HBOOT How to revert back to an earlier version of HBOOT but it seems I need clockworkmod to do that

So my question is. Is there a way I can proceed from here or am I stuck waiting for an official root for 2.2?

HTC Incredible :: Way To Downgrade Radio / Turn Down Power Consumption?

Sep 9, 2010

seems like anything using 3g drains my battery. slacker player saps 30% of a 2600mah battery in a single hour. If I were to be conservative, it would be 25% of a 2200mah, accounting for other parts of the phone and possibly a low quality battery. Even then, that's horrible. It didn't used to be this bad. And now I suspect it's a combination of a new radio update that boosts signal by consuming more power, and the fact that 3g coverage is weak where I'm at (though it worked good enough before the update). So if there's any way to downgrade radio without losing froyo or other phone functionality, or directly influence power consumption of the 3g radio, please let me know.

I've been bouncing all around to different forums and guides and none are clear. The XDA thead by toast also says his root doesn't allow custom ROMs but I've seen custom ROMs mentioning toast?

So i got to the step on XDAweb's guide to root 2.2 where: cd /data/local./flash_image misc /sdcard/mtd-eng.img then reboot the phone. it went through flawlessly and it rebooted. now, i have no video on the screen, its all black. i pulled the battery, i tried to abd to it, but it said device not found. i can hear the startup chime, feel the hauptic force feedback, so i know the phone itself is working, but for some reason the screen crapped out! I use this phone for work as an IT professional and im kinda up a creek.

Motorola Droid 2 :: Can I Downgrade From 2.2 To 2.1.1?

Sep 4, 2010

I have a Motorola Droid 2 on Verizon. It is not rooted, just a basic phone with a few apps. I'm currently running Froyo 2.2 and I would like to get back to 2.1.1, or frankly any version other than 2.2. I got my phone last year in November and it was running version 2.0. Since then I have upgraded to 2.1 and 2.1.1. Around a month ago, the 2.2 update was pushed to my phone, and after reading great reviews about it, I was excited to upgrade. I allowed the update to my phone and since then I have experienced constant problems with it. Another "update" was pushed to my phone a week or so ago, but I checked the version after the update and it was still 2.2, so I'm not sure if it actually did anything, and I still have the same problems.

Since updating, my web browser freezes up regularly making it unable to use. Some of the applications I use frequently crash or freeze up (such as Pandora). The phone is much less responsive; I sometimes have to just put it down and wait for it to start responding to input again. When I try to select a text message to read, most of the time it enters a different thread than the one I selected. I'll then have to back out and try to select the text message I want to read again, and it always works the second time. The phone often misses calls; it doesn't ring or anything. I'll just get a voicemail, which is the only way I know I missed the call; no other notification or anything. It no longer plays WAV files. About half the time I try to load a YouTube video, or even launch the YouTube application, I receive a message that there is no internet connection, even though I'm using the web browser and I know I have an internet connection. Before upgrading, I almost never rebooted my phone, but now I have to rebooted multiple times a week because of the freezing and crashing of apps. Basically it has went from a smartphone, to just a phone. I am so frustrated. If I can't downgrade, I think I'm just going to have to get a different phone. I have found posts on how to downgrade other phones from 2.2 to 2.1, but I'm not sure if they work on the Motorola Droid 2, and I don't want to risk being completely without a phone, since I use it for work and personal use. The other guides I have found for the downgrade seem to specify they are for phones other than the Motorola Droid 2.

Motorola Droid :: Downgrade From 2.2 To 2.1

Aug 6, 2010

I have done a decent bit of Googling and searching in this forum for this answer. I was wondering if there was a way to downgrade from the manual update 2.2 back to the 2.1. I have been having such a hard time with my Wifi since I upgraded I just would like to be able to go back to a better working version. I tried putting the manual 2.1 update.zip in and doing that, but it just says "error in sdcard update.zip status 2" I couldn't find what status 2 means, but I imagine in layman's terms it means something like "You can't downgrade like that dummy!" So, I fear that I am just stuck until our update gets updated.

HTC Eris :: Downgrade 2.1 Root To 1.5 OTA?

May 27, 2010

I followed all of these instructions to downgrade my wife's rooted 2.1 and it seems to have worked fine. I've got it back to 1.5. She wanted the OTA upgrade because the 2.1 rooted version was giving her the silent call issue. Again, I went back to 1.5 because I wanted the OTA update. After doing this, she got the OTA update notification, it downloaded, processed and then failed. I've also tried to install the OTA manually and it won't work. The hboot is version 1.47. Has anybody had success downgrading their 2.1 rooted install to 1.5 and then getting the OTA update to work? I'm back at 1.5. What should I do next to get the OTA update working?

HTC Desire :: Can I Downgrade From 2.2 By Flashing

Aug 7, 2010

Given the number of little bugs and issues being reported with 2.2, I'm actually a bit wary of installing it on my phone.

I have an Orange phone which I debraded by flashing the generic ROM. I was wondering - if I install 2.2 and then don't like it, can I revert back by re-flashing the original generic ROM again or won't the installer let me "downgrade" like this?
