Downgrade 2.3 to 2.2 - EVO 4G Q&A, Help & Troubleshooting

Hey guys i updates my second stock evo to 2.3 the Sprint OTA update and now my camera and gallery are borked. When i launch either i get a black screen... Any help is appreciated

Can i just flash a PC36IMG from 2.2??

If you took the OTA you can't downgrade it. Sorry, might want to swing by a sprint store since you're stock. Try wiping in settings to factory reset or pull battery.

Same thing happend to me.
You can load the 2.3 via PC36IMG and that will reinstall everything.
That fixed my stuff and everything is working again.
Sucks we can't downgrade.

i do have s-off though.....

[Q] HELP PLEASE Return EVO to Stock ROM so I can get OTA update for 2.2

OK,
I used the Simple Root method to unlock my EVO. I'm clueless as to how this benefits me and what to do with the rooted phone now.
Of course Sprint released the OTA 2.2 update just days after I did this and I just want to return my phone the the stock ROM. I've tried several methods and none work. Everything I do leaves me with the Superuser Permissions still on phone and I cannot complete the OTA 2.2 update. I don't want a custom ROM, I just want the stock OTA ROM.
Someone please help with a step by step of how to remove the Clockwork Mod boot system and return my phone to out of box condition so I can get up to date.
Thanks (I hope).
Flashing the stock RUU maybe??!?!?!?! lol
tried that
Yes That would seem logical. I tried that but it doesn't get rid of the boot system which is preventing me from getting the OTA 2.2 update. I want to revert completely.
Admittedly I don't really understand all this rooting business so it does me little good to have my phone rooted.
I can revert my ROM but it doesn't get rid of the clockwork mod boot system and therefore I still cannot complete the OTA update. Every time I try the update it starts to install and then goes to a page with a caution triangle and just freezes there and I have to pull the battery and reboot and I'm at the same place I was before.
I don't understand how to flash a ROM anyhow.
You can download the 3.26.651.6 RUU .exe from this mirror
http://www.mediafire.com/?3z4zbt3vco1ijs7
USB your phone to your computer and run that exe. You will end up with the same stock froyo as the the OTA update will ultimately give you.
If you used the official 1.47 RUU, and it completed properly, then you should be completely stock. It wipes all the partitions and puts you back to stock. You can also look for the stock .6 Froyo rom that's been rooted. I know I've seen it around here somewhere. Grab the one that is Odexed, as it hasn't been tampered with at all except to add SU permissions.

[Q] 2.2 update problems.

Ok I have looked and no one has had my unique problems...
When updated to 2.2 I had my S-OFF but I recently turned it back on and did a full factory reset, which didn't work, trying to fix some update bugs with my ATK. The recovery is CWM and I want stock and it wont let me do a full reset. Any idea's on how i can?
There was a thread around for converting to 2.1 for the update. If that's what you're after. If your after 2.2 then you could try the RUU that was posted here just before the official OTA came out.

Need to re-flash stock 2.2

Hopefully you guys can help me, you haven't let me down yet
I am having problems sending/recieving mms messages. I called verizon and they have opened a support case after not being able to fix the problem.
I keep thinking I may have taken off something I shouldn't have with system app remover...
I am currently running the stock OTA 2.2 rooted with S-off, and the Hboot bootloader.
I want to flash the stock 2.2 back to the phone and see if that clears up my problem, but I'm not entirely sure what steps i'll need to take.
I've downloaded the RUU from http://forum.xda-developers.com/showthread.php?t=765596&page=34, can I just hook up the Dinc to my computer and run the RUU to flash my phone back?
Can I just use the factory reset option from the recovery screen?
What would you suggest?
Thanks in advance!
Im having the same problem receiving picture messages im running redemption 2.0.4, please keep me updated if flashing the stock 2.2 helps
I used this (http://forum.xda-developers.com/showthread.php?t=765596) last night to get to stock 2.2 with the latest radio. Than I rooted with the latest unrevoked. I would use appbrain or titanimun to back up your apps first.

I'm not using a custom rom, just the stock vzw update that was posted in other threads/distributed OTA
But yes, I flashed the rom to my phone last night and was able to keep root/bootloader/etc...plus it solved the problem!

3.26 (rooted) to 3.29 fails. Why?

Greetings all,
I am running 3.26 and rooted it using Unrevoked3. It is working great, including 4G here in St. Louis, etc. I searched for an answer to my question, but couldn't find an applicable answer. Here goes:
I have a good nandroid backup, and over the weekend, I tried to upgrade it using the 3.29 OTA update. The update failed, with the exclamation mark inside the triangle and the green guy to the lower right of it. Had to pull the battery, but it booted back up just fine.
Is the 3.29 updater failing because it sees root/s-off? What do I need to do in order to be able to get 3.29 on? Unroot and turn s-on somehow?
Thanks in advance, just trying to learn my way around.
-Rob
Well Rob when I did the update I was s-off so I know that does not make a difference. I rooted my phone the downgrade,unrevoked3, and unrevoked forever way. When the OTA came I put a stock ruu on my phone which probably unrooted it but kept the s-off. I then updated the phone then reinstalled the old bootloader and recovery soit was back to rooted. I don't know if that might help or not just thought I would tell you my way. Probably easier ways out there

firmware 2.1-update1 HTC Evo 4g

Hey guys, so I been trying to root my phone for like the last 3-4 days ever since I got it. Sadly, I cannot root it and have given up hope, and just wish to get my 2.2 firmware back, I've got the stock rom now (sprint lovers?) and everything seems good, except for the fact that my firmware stayed at 2.1-update1, and I can't find a way to get it back to 2.2
Can anyone help me with this?
(Also does anyone live in Fresno, CA? Willing to pay to get my thing rooted )
There are so many things wrong with this question.
If you never rooted, how did you flash a rom?
I have no idea why it'd say you're still on 2.1 if you installed a 2.2 rom to begin with.
How the hell did you downgrade to 2.1 from 2.2?
I don't think they flashed at all there on the stock sprint old enclair ota, but how did they get on 2.1? I suggest you do a ota update. Go to settings - scroll to the bottom and choose system update then choose software update.
Maybe that will get you on froyo 2.2.
Best of luck.
!πf€©£€d Evo 4g
I have tried going to system update and choosing firmware update but it claims there is no update available. I dont know how I downgraded, I was attempting to use autoroot v2.3 and it installed a different rom that says "Quietly Brilliant" at the start-up screen, but now I have it back to stock. Where the original sprint load up screen came up.
Everything seems good except for the fact that it says I'm running firmware 2.1-update1 and can't use my flashlight, on my phone to use the camera light as a LED light :S
First off, if you are rooted, NEVER EVER try to update your phone. You could permanently lose root. Every single guide to rooting tells you this.
Second, just download and run a stock ruu for the latest version of the stock rom.
