I would like to know if it is possible to upgrade/downgrade an android phone (samsung mostly) with official firmwares without the need to root? The reason is that some testing is needed on these devices and only with official firmwares it would be valid. And at will it would be nice to be able to switch versions for different test purposes.

I bought LG VU II (F200L) in perfectly working condition, it almost new. After installing LG PC suite and connecting it said new firmware update is available so I proceeded which was done successfully but since then touch screen is not working properly.
Usually it responds ok but main issue is back button is not working anymore, and sometimes when I press power button to unlock screen it responds very weird and not so responsive as well as sometimes doesnt responds or opens apps that I havent even clicked.
I tried to restore, emergency restore, LG Flash tools and used correct KDZ files to flash roms successfully but nothing seems to resolve this issue.
If I upgrade the firmware to Froyo 2.2, can I downgrade again if I find it too buggy like others have?

View 1 Replies View RelatedThere 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:

Now I would like to upgrade to the latest firmware. I found out that I needed something called Kies, so I downloaded it and followed the instructions - hooked up the phone after checking debugging, etc, but I got an error that said I don't have authorization or something.

I experienced no problems with the installed firmware (versjon 14) with my X10, but I read on a forum that some people had gotten their device a bit faster and smoother after installing the update that is available (version 16). I installed the update and now I regret and wish I never would have done it.
Now I have the problem with the "a" butten. When I hit the "a" button, I just get that the button was pushed and nothing happens in the textfield, so I have to push the "a" button twice to get something.
I couldn't find my wireless internett that was turned on, and in some of the programs when I write, nothing shows up in the textfield, but I can see that the text registered by the device because I can see the wordexamples coming up as I write. I wonder if there is a way to downgrade to the preinstalled firmware?

View 6 Replies View Relatedyesterday I flashed my Galaxy Ace 2 with the JellyCreamMessi10 Rom.
The update worked fine, but not so the Rom. It looked quite well, but didn't detect my SIM Card.
So I wanted to downgrade my phone again to the original firmware with Odin, which also worked well until the phone said "Now rebooting...".
Nothing happened, the phone did not reboot, so that I powered it off and tried to power it back on.
Unfortunately, the Ace 2 does not react on any button, display stays completely black.
Tried several things like connecting the phone to USB and inserting the battery, afterwards, but nothing happens.
For me it looks like my phone is broken, but how I can get it back to live?
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:

I have a Galaxy s4 (i9500) and a linksys cisco e900 router
Recently my isp asked me to upgrade the firmware
Until I updatee my firmware everything was working fine
After the firmware upgrade I am experiencing the following issues:
At the beginning when I conmect to my wifi everything works fine for the first 5 min, all apps work flawlessly, then suddenly my phone only uploads date (up arrow only) but no down arrow n then my apps such as whatsapp, fb messenger, etc do not recieve any data until I goto those apps and stay in there for about a min. Then I get all my whatsapp messages sent about a min ago . But my browser seems fine..and the speed there is good.

Is there any word when a method to root and install custom firmwares on the Arc (such like Cyagonmod or something)?
I've tried just about most of the common methods I've found so far, and I've gotten nothing.
The only thing I can think of is the fact that the Arc is suspiciously similar to the Nexus 7, so can look into root and see if a port can be made for the Arc.
I have new firmware on PC for my Samsung phone, intended for flashing with Odin (i have PHONE, CSC and PIT files). My question here is, is it possible to root this firmware before flashing it. The case is, my phone is now rooted and I don't want to loose root access, but I would like to flash this new firmware, cause with this one i have occasional problems (force close of apps, freezes, loosing wifi connection, etc). I've searched every where but haven't found anything. Only Mobile Odin have such options, but my phone is not supported yet.

When I tried to root again, all my attempts failed, I used SuperOneClick 2.3.3 to root my fone again, but it failed after STEP 7.
Why can't I root my fone now, has SAMSUNG patched the zergrush exploit?
If so how do I root again?, I mean it should be safe enough to try coz I don't wanna brick my phone....
This is my first post and I am new to Android so excuse my ignorance if this is well documented and common knowledge. I have a stock ADP, firmware 1.0, no updates no mods and of course I want to get the latest features such as voice control, latitude etc, and so begins the fun. Why is there nothing official that can be easily found which states what is going on for people that own the ADP? I must have read dozens of articles showing update procedures and claiming to have leaked OFFICIAL developer updates and only recently did i find 2 thread that eventually end with something stating there is NO official update for developer phones yet.
I have 2 gripes about this:
1. Why no official and clear statement from the development team to clarify this before people start scrambling desperately to install leaked versions that are false? (I know I almost did) 2. Why as a developer do I have to wait for features that are already available to end users?
