anybody now to downgrade 2.2 back to stock 2.1, i found som info but refers to the nexus 1. it advices to unlock the bootloader by flasing a .zip file (goto androidtechnical.info and get the passimg.passion_.zip file load it to your sd card root name it passimg.zip (just one zip ext) and flash wahla)
I was wondering if i can apply this to my EVO and be done with it?
just flash to 2.1 rom.
whats your reason?
Downgrading will only be possible once it has been determined how to root an unrooted 2.2 EVO. That is not possible, at-the-moment. We will just have to wait....
if you aren't rooted currently there is no way to downgrade or root 2.2.
so in short you are stuck at stock 2.2 until the amazing devs figure out a new bug to exploit to provide root.
but just to confirm, if i'm rooted since day 1(original 2.1 root) and i installed a rom from XDA(OMJ's 2.2 froyo) i can downgrade simply by installing his older 2.1 rom right?

Not sure if you can flash a 2.1 OMJ over a 2.2 OMJ (or similar) becasue I haven't done it ( I don't think you can), but if you run simple root again (or do Toastcfh's part 2 manually) and load the engineering build, you should be able to again flash a 2.1 to downgrade...Same idea as what you need to do to downgrade in order to flash a RUU if you have to send your phone back for any reason...

i tryed that, Froyo locked up my bootloader. I have too many issues with 2.2 for my taste. I want to go back to a rooted 2.1 and flash a custom Froyo Rom

yes! this is what I want to be able to do. having an original 2.1 root allows you to flash any ROM Sprint Stock or ortherwise, its almost like changing skins but your base never changes. The only time things change permanently is when you do an UPDATE. Doing an UPGRADE only brings the eye-candy that only a custom ROM can provide.
Hello
Im new to posting, but not new to the forums. I read this forums daily. I would like to take this time to say thank you to the whole community, I personally have benefited from all the custom roms and tutorials.
I have a question:
I was on 2.1 rooted and decided I was going to unlock my nand and get Fresh Evo rooted 2.2 rom (which is amazing by the way) so I did a NAND backup before starting the process of unlocking my nand and flashing the Fresh 2.2 evo rom. Now that I am on the 2.2 Fresh Evo rom I would like to restore my 2.1 nand backup to take a look at some important data on there, after restoring that backup can I come back to a backed up nand of 2.2 Fresh Evo rooted rom without having any problems?
Simply, can I go from 2.2 rooted to a NAND backup of 2.1 rooted stock, then come back to my 2.2 FreshEvo rom?
I appreciate the help!
Thanks

why wouldn't you be able to? just make a nand of the freshevo rom
EDIT:
<--- NOOB AS WELL
Yes you can. I keep a Nandroid of Rooted 2.1 Stock, Rooted 2.2 Stock, and my latest CM6 Nightly that works handy at all times.
Thanks!
So just simple restores will do it when switching? No need for cache wipes or anything?
Hi could someone please tell me the best way to get the official verizon OTA? im currently running skyraider sense 3.0, rooted, with the 2.15 radio, and s-off.

The insructions say stock, but it should work fine for custom ROMs.
I followed that thread and it worked fine. Was getting the USB error 170 on my Windows 7 machine, so I grabbed the rom.zip file from my temp folder, tossed it on my SD card and booted into HBOOT (outlined in steps 5-11).
I went from SkyRaider 2.5.2 back to 'stock'... I had s-off'ed when it first came out though so that I could regain root. Although from the looks of their Twitter post, the new unrevoked forever tool will be able to get root and s-off stock Froyo phones too.

I just did this last night to send my phone in for a warranty. Their is a stock PB31img.zip you can download that will take you back to stock 2.1, radio and all. You can then wait for the ota or use the ota ruu to get stock 2.2.
Thanks so much.

I was just wondering if anyone has installed a rom that was made from 3.70 and then tried to go back to a rom that was 3.30. i want to know if it can be done or has anyone had problems doing it. thank for all the info.
First Post!!!
I love this new Rom! It is by far the fastest and most aesthetically pleasing Rom I have ever used. Keep up the good work dev! Can't wait for your updates!
Seriously though, to answer your question, I have updated to 3.70 and then rolled back to 3.29(originally came on my 0003 Evo) with absolutely no problems. I even updated to 3.70 then unrooted back to 3.29 and got the update via OTA and then rerooted. It shouldn't be a problem as long as you use the RUU of the Rom that is compatible with your hardware.
I have not had problems. Doesn't mean others haven't. If you updated your radios then maybe. I haven't gone back to a 3.30 since the switch.

so you have gone from 3.70 back to 3.30. i am asking because a friend of mine tried and all the phone does is boot loop. the only roms that work is 3.70

Have your friend try flashing the wipe everything zip from calkulin. Also does he have hardware 004? 3.30 was only rolled out to 0004 Evo's. If not have them try a 3.29 Rom.
No I will have to let him know. Do you happen to have the thread info.

The reason it bootloops is because the 3.30 roms use HTC kernel #17. When u flashed the 3.70 you probably also updated your PRI to 1.90_003, which requires HTC kernel #15 or a custom kernel (e.g., netarchy 4.3). So the kernel is what's causing bootloops for your friend.
Tell him to wipe everything then flash the 3.30 rom. Then before rebooting flash the custom kernel. It'll boot fine gauranteed.
Basically the PRI 1.90_003 cannot use any HTC kernel before #15 (which came with the 3.70 update). So any HTC kernel prior will cause bootloops.

What happen was he was using a myns rls 4 and then installed an rom with 3.70. When he tried to go back to myns everything went wrong.

Androidious is right. Use calk's wipe everything then try flashing Myn's. If that doesn't work your friend may need a custom kernel, or download the HTC #15 Kernel and flash that.
My first guess on this stuff is he is using Clockworkmod recovery and its not clearing his Dalvik cache. As it has been stated many many times that it doesn't work. This may not be the case but is my first guess.
Thank you everyone for all the info.. Been a great help..
Funny...I'm currently having the same or a similar problem...I wanted to try the new 3.70 based ROMs, but now I can't go back to my NAND of myns 4...I've tried the wipe zip and I even tried to roll back my radio...I'm literaly stuck at the slash screen
I've been having this issue too, except I've tried installing new roms with htc kernel 15 and with netarchy kernels and all roms still boot loop for me with the exception of Ava and Evio. Maybe the link was bad? Does anybody have a link for htc # 15?

I had this same problem.... I had to go back to step one to rooting my phone again since it wouldn't let me restore my phone.

So this is the story.
For one reason or another, messing around with Titanium I lost com.htc.dialer.
I wanted to replace it so I flashed the PC36IMG from root and started the whole rooting guide again, keeping AR v1.8.
Then following the guide, I flashed another PC36IMG which is SprintLover's Rom.
Everything works fine now except that whenever I try to flash Myn's Rom again, or any other rom, it just freezes at the splash screen.
the only way I get back is by restoring the NAND backup I did of Sprint Lovers. Not even the NAND I did of Myn or any other Rom works.
I've been pulling my hair out for this one but I can't seem to figure it out.

BTW if this turns out to be something I missed on the search and it was something really easy...don't flame me that much xD
I was getting the same problem, until I flash fresh and got it to work, i think the problem was our current PRI doesn't match MYN 3.3 software since that PRI version came out with the 3.7 software which is what fresh is based off of

That is correct. Also, I believe in regards to RLS4, that the htc #17 kernel that it comes with is NOT compatible with the newest radio (which you have) Best way around that is to flash a custom kernel, pretty much any one of nets, ziggys, or ms's sbc kernels. So I would try downgrading your PRI to 1.77, flash RLS4, then while still in recovery, flash the kernel. It should work then.
The other option is to wait for RLS5, which should be out relatively soon. That is based on the 3.70 software, and your current radios and PRI will be needed to run with RLS5 anyways. Good luck, and by the way, it's worth it. Myn's ROM is, in my opinion, by far the best sense ROM.
if you flash a custom kernel after flashing myn's ROM, then reboot. you will be fine. stock HTC#17(stock kernel on RLS4) does not play well with PRI 1.90.
-or-
just wait a few more days for final version of RLS5 to come out based on the latest OTA (3.70)....
Thanks everyone =D
I flashed CM6.1 for now after flashing the Eng Hbootand I'll just wait for RL5. It was such a hassle having a half broken phone on my first day back to University with no PC to hook up and change the files...not going to play around with it till the weekend xD
