I have been Googling/Youtubing/ everything to try and find a way to downgrade to version 1.5 so i can root my droid eris. I just found that they only way to downgrade is to have a rooted phone? so in order for me to root my phone...i need to have an already rooted phone?! my question is, is there a way to downgrade from 2.1 to 1.5? or is there seriously not a way?

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 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:

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.

View 16 Replies View RelatedI received the 2.1 OTA and ran the update. My phone is much more sluggish and I would like to revert back to the 1.5 software. Is this possible???
View 1 Replies View RelatedI found this on Android Central (thanks to IzelTokatl) and someone there did verify it worked for OTA 2.1 phones. I tried it on my leak version 3 phone and I got the Hboot error again. I'm thinking this does not bode well for phones with the leak as once Verizon releases the upgrade for download from PCD or HTC we still won't be able to use it until the Hboot problem is fixed. The following instructions for doing the downgrade to 1.5 are cut and pasted from the Android Central forum and I edited them for PC's: Download the MR2 Upgrade Eris ROM from verizon partner: personal Communications Devices
1. Unzip the file
2. Plug your phone into your PC.
3. Navigate to folder ADR6200_MR2_Upgrade
4. Run .exe file in the folder (RUU_Desire_C_Verizon_WWE_1.17.605.1_release_signe d_with_driver.exe)
5. follow on screen instructions.
I apologize profusely for this, but I cannot seem to find it through search. I am looking for the download for the official 2.1 so that I can overwrite my v3 leak. Can anyone point me to the thread with the download?

View 14 Replies View RelatedI don't want to beat a dead horse, but I have searched around and i have not found a good explanation as to why those with the 2.1v3 leak cannot manually install the official OTA file that was posted here.
Anyone have an explanation for this? I read that it has something to do with a different HBOOT, but I'm not really understanding it. Do you think we will every be able to get the OTA so that we can go root? I quickly jumped to the 2.1v3 leak without fully understanding the benefits of root and now, after more research, I really want to go root.
If I already rooted to one of the 2.1 leaks will I have to do a factory reset to upgrade to the official? If so would I have to talk to Verizon to get my phone set up again? (IE: Service?) Sorry, I'm kind of knew to this .

View 6 Replies View RelatedI 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?

View 8 Replies View RelatedHas anyone been able to get wired tether for root running successfully on Ivan's Official 2.1 ROM? It was included as one of the default apps, yet I can't get it to work on 7 Ultimate, XP Pro, or OS 10.6. I'm going to be in the car for a few hours today with a thinkpad running XP Pro, and I wanted to try out wired tether. When I plug in the phone just for charging, a new driver is entered as Android Phone and I'm fairly sure Android Dev Bridge. When I start wired tether, those devices disappear and and a USB device that cannot start or has the wrong drivers is on the bottom of the screen. When I used wired tether (internet sharing) in EE 2.0.1, all OS's would immediately set up the phone as an NIC connected to the internet with the exception of XP which needed the correct drivers. With wired tether in ivan's official, I get nothing; no driver setup screen or any connection.
View 5 Replies View RelatedI 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.
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.
