Help please - Looping at HTC EVO 4G boot screen

Ryan07 · #1 (**permalink**) 06-13-2010, 01:08 PM

As part of my tinkering, I decided to restore a backup I made after rooting. Now I am stuck at the initial boot screen (htc EVO 4G). It lasts for a moment, the phone restarts, so on and so forth.

I've chosen wipe data/factory reset with no luck.

I can still get into with adb and from the /system/app folder, the reset seems to be successful as all apk files are back.

From the Android Sytem Recovery screen (where I ran the reset), I have this error:

E:Can't open /cache/recovery/command

Looking into that folder with adb, all I see is a log file.

Thanks for any assistance.

I've downloaded the stock ROM and pulled out the rom.zip file. Would it help to (somehow) get this on my SD and let it flash?

Problem solved. I renamed the stock rom.zip to PC36IMG.zip and let it flash as with root.

Now the problem I have is that I formatted my SD card through my TP before adding the file and now it says it isn't installed. Any tips for that?

Okay, so I flashed the stock ROM through my SD and ran the root update through my SD, but the phone keeps telling me it has been removed.

Now when I plug the phone into my PC, it's asking me for "Qualcomm CDMA Technologies MSM" driver.

I had this same problem..... none on here could help. All I can tell you to try is to flash the stock rom from your computer by running the ruu. If u get an error message than u are in the same predicament I was in. I brought it back and got a new one.

Thanks mrpigg. I was sent this from a friend trying to help:

So it will either work or it'll have to go back.

sounds like you forgot to wipe before you flashed. always wipe/factory restore, wipe cache, and wipe dalvix cache before flashing. wipe and reflash stock or custom rom...also, the htc sync information as well as a couple other things were stored on the original memory card, your phone will rebuild the folders but not the sync. if you formatted you deleted them. oops! I will look and see if i can copy in what you need...

...this should be all you need.

Lemme know if any of this works. Because if so i will save this thread in case i or any one needs it in the future

Sprintgirl, I downloaded the Sync from HTC and all the folders I wanted to keep (some data, photos, etc.) I saved before formatting.

I have recovered my SD card but I haven't gotten to the USB restore yet. Now I have to power off my phone to charge it but I'll take care of it tonight.

That link I added was spot on for me.
