[Q] 3G Not Working after Downgrade?

Hey all, long time lurker, first time poster....unfortunately....
So after sitting on MIUI for a good while, and having a blast with it, I decided to try out some other ROMs. I was interested in seeing Cyanogen 6, and so I went about attempting to get the latest stable, non RC ROM onto my EVO. I read into it seeing that I needed to downgrade my hboot, and found the image without a problem (running the .76 right now, had the 9something one before...)
Well, I downgraded my hboot without an issue, flashed the Cyanogen, and got into a splashloop. I figured out it was becaue I hadn't wiped my cache or data before flashing the rom, so I went into the Clockwork Recovery and wiped those, flashed once more, and it booted into Cyanogen perfectly!
Well, almost. I don't have 3G now.
For some reason, I am unable to connect to 3G no matter what I try. My nandroid's broke due to the hboot downgrading, rewiping the cache/data and reflashing cyanogen did nothing, and now for some reason, when I attempt to go back to MIUI, it still will not allow me to connect to 3G. I can send and receive texts, and make and receive calls, but alas, no data connection.
Should I get a fresh RUU and stock hboot, upgrade and restart from scratch? I just want to get back to MIUI at this point with a working, data enabled phone.....
If that's the case, that I do need to start over, where can I find a new hboot for the EVO that isn't .76? I'm pretty saavy when it comes to this stuff, but for some reason right now I just can't figure it out....
HTC EVO running MIUI v0.11 stable
.76 hboot w/ Clockwork recovery
Broken nand backup
whatdo?
Thanks in advance for the help

Sorry for the double post, but I resolved my issue.
I am unsure of what exactly went wrong, but I figured it was somewhere between downgrading my hboot, and flashing the CM 6 stable ROM that my 3G data got scrambled....
So! Using ROM Manager, I made a backup of my working (non 3G) MIUI image, and flashed the Odyxed version of the RUU found here (http://forum.xda-developers.com/showthread.php?t=836728). After flashing in Recovery, it booted into SenseUI, and worked like a charm!
My 3G hath returned, and issues have been solved. It's nice when you're able to fix things on your own, though I couldn't have done it without the help of that handy dandy search button, and the RUU keyword
Oh, yeah, and I guess xxbabiboi228xx as well.....maybe....^_~

[Q] Help please!! anyone.

Trying to install Vaelpak 3.0 and I am having 1 hell of a time. I'm thinking it has something to do with my radio wimax pri nv ect.... because earlier in the week I tried flashing the combo and everything went to hell on my phone. I since then had to flash back to the previous radio and then had vp 2.3 running fine again. After that I learned that it was kernel specific problems with older HTC kernels so I flashed netarchy's and then went back to the radio combo and had this problem with my CPU load at 100% and always running at near 1ghz. Then I learned if your rom is not based on the 3.3 that the newest PRL with continue to overload your CPU the entire time. I hadn't gotten this problem really fixed by the time I found VP 3.0 and figured flashing this would just fix my problem with the newest PRI because its based on the 3.3 update.
After a full wipe (data, 2x cache, 2x dalvik) I flashed 3.0 only to get stuck in a white screen boot loop. So I DLed the file from another link moved it manually to my SD and flashed that... same problem. Then I decided I would restore my 2.3 through RA install rom manager and change my recovery over to clockwork to try to install the rom. No go. Then I flashed a previous version of 2.1 used rom manager to put RA back on (I've found this more reliable but at this point who the hell knows). Went into recovery and restored my backup made as of this friday. Still having the problems with the CPU load so I went back to recovery and flashed the older radio combo but noticed this doesn't have NV on it(not sure what NV is either). But all seemed to be working fine for moment until 2.3 started randomly restarting on me. So now my 2.3 isn't working and can't get 3.0 to flash.
Next thing I thought to do was to wipe all again flash 3.0 and then flash netarchy's kernel over the htc #15. BAM!! I get it to run through the boot into the set up menu asking for my gmail account. I enter my account info and wait, wait, wait, then it says cannot get reliable connection to google servers (also I notice that my data instead of a 3g icon says EvDo). Well now this can't be good. I try to turn on my wifi it says that wifi cannot perform search. I enter my network manually cannot find network. I've tried updated profile pri and everything else from settings and always get same error with communications saying call sprint(don't wanna do this will immediately void my warranty I'm thinking). Now the last thing left for me to check is if I can get 2.3 up again and check my wifi ect... through that.
Wipe, Wipe, Wipe, flash older radio combo, flash previous NV that wasn't in combo as far as I could tell, restore 2.3. All seems to be going well until I try my wifi. Cannot search again. WTF?? then instantly black screen to no where. Pull battery try again, get into the settings and then black screen back to Vaelpak boot animation. I am completely lost here I could really use some help. Like I said in the beginning I have a sneaking suspicion it has something to do with the radios combo ect... but can't figure it out on my own.

Well in case this has happened to anyone else and it is likely to happen somewhere down the road from people upgrading to roms based of the 3.7 update. The quickest fix I found was.
1. DL Unrevoked Forever from web page and flash it
2. Find a stock ruu for the 3.7 or do what I did and just DL Sprint Lovers PC36IMG.zip place in root of SD card and boot into hboot. Install the ruu.
3. Go to settings>software updates and update the PRI and the Profile
4. Remove the PC36IMG.zip from root of your SD card
5.(only applicable if you used the stock ruu) take your recovery of choice name it PC36IMG.zip and place in root of SD card. Boot into HBoot and install
then remove that from root as well.
6. Flash the Rom you were wanting to flash. This will take care of all Radio, Wimax, PRI, NV, and other problems between 3.7 based roms, Kernels and Radios.
Hopes this helps someone along the way.

Went from CR 6.1.1 back to Warm 2.2 having problems

Basically when I install the warm 2.2 rom it will hang on the htc evo screen. I had flashed this rom earlier this morning and it flashed fine. Ever since I've flashed CR 6.1.1 this afternoon i've been having problems. Even my baked snack 1.9 rom is very slow but comes up after either sitting at the Green HTC text after it has booted. I had to power down the phone a few times to even get that to come up. Is there something I'm doing wrong here all the sudden? I am clearing davlik and partition cache, even tried to wide data/restore to no avail. I'm at a loss here. Anyone have any input here? As I type this, I just did a complete wipe and tried to install Warm 2.2 and it is just sittin at the white screen that says HTC EVO 4G. Powered down a few times and removed battery for a minute to no avail, still just sits at that white screen.
I am able to restore from nandroid. I am also able to isntall a few roms.
Thanks
Dave

Uh, what kernel/radios are you using? I had similar problems when I flashed the all in one radio combo in calk's thread.

That is exactly what I did too, flashed the radios. How did you resolve that issue? I dind't even think that would cause these types of problems.
I just put on Fresh 3.5 and it installed fine. I am using kernel 2.6.32.17-gee557fd (under it says [email protected] #15 (Which kernel would that be?) PRI is 1.90_003
Well I downgraded the radio to2.15.00.09.01 and I got past the white screen and into warm. THanks much!! I had no idea that a radio would just cause it to hang like that. So the only way to revert back to an old radio file is to install it? A nanrestore doesn't do that it appears??
Thanks very much

Help with New Evo with HBoot 2.16.0002

I just got an replacement evo with HBoot 6.16.1002 and i rooted it with s-off with revolutionary method. However no matter what rom I flash(CM7,evodeck,sense 3.5 roms), they all freeze up on me after initial setup of google accounts and etc... the only thing that works is the stock rom. Can someone please help?

Are you doing full wipes when flashing?

I do full wipes, i wipe everything except sdcard at least three times before flashing

the bad part is, i tried several roms and they all do the same thing. I even unrooted my phone then rooted again and im still having the same issues. The stock rooted rom works perfectly.

[Q] Broken Wifi

I recently unrooted my EVO to exchange for credit for an upgrade. I decided to keep it as a backup. I was on Hboot 2.18.001 and I rerooted through HTCDev, then PC36IMG to 2.2 to get S-OFF, ending up with Hboot 2.10.001. Somewhere during this rooting process I lost Wifi. When attempting to turn Wifi on, it flickers off and on and reports back that it is unable to scan for networks. In CM7, it causes more problems like force quits and lag. I am using this as a wifi only device as a backup music and game device.
I tried downgrading and upgrading the radios, I tried changing to hboot 2.15.001, I tried different ROMs (AOSP, ICS, Sense, 2.2, 2.3), I tried redoing a PC36IMG, I tried combinations of all of the above. I also tried nandroid restore. Still no Wifi. I am using Smelkusmod recovery.
Currently I am at a stock latest OTA ROM with root.
Any suggestions?

just wondering, did u ever drop it? thats what happened to my evo shift and i couldnt do anything on it other than install roms. i dont remember the version of the firmware but there was one that made wifi useless, meaning like it would turn on and find signals but wouldnt connect. my suggestion is to start from scratch, get the 2.2 ruu stock, before rerooting check to make sure wifi works, if it does then another suggestion would be to follow zedomax's rooting with revolutionary (witch i currently have now). if none of that works then eather sell it for parts or take it to sprint to get a refurbished one.
Good luck!
