[EVO 4G Q&A, Help & Troubleshooting] dwreck_:
Update

So I never could fix this issue, although I got some really great suggestions and learned a lot from cutthroatamft.

Ended up just deciding to completely brick the phone (in case the Sprint tech might check my bootloader screen for S-OFF). To do this, I just removed the battery while I was flashing an engineering image (while it was updating the radio). After that, not only would the phone not power on at all, but the charging LED wouldn't even light up when plugged in to a power source. They gave me a refurbed Evo.

Haha, I was able to fix my Evo (dont remember what I did) but I have since sold it.

I wish I could, but honestly it's been so long that I dont have any idea.
[EVO 4G Q&A, Help & Troubleshooting] thanamesjames:
Thanks cutthroat.

dwreck, at what point did you pull?

I've pulled it twice while it was updating Radio_V2, with the red bar about 1/3 of the way, and nothing about my phone seems to change.

Did you pull a little later? Or did you pull during Radio_Cust? That thing is hard to catch, it updates quickly.
[EVO 4G Q&A, Help & Troubleshooting] cutthroatamft:
My friend says it took him about a hundred times to fully brick his Evo. Just keep trying I suppose.
[EVO 4G Q&A, Help & Troubleshooting] thanamesjames:
Sprint was backordered on Evo's. It might take me more than a week to get another one, and it's still 35 bucks. Cutthroat or dwreck, do either of you guys know if it would be safe for me to send my Evo into HTC? I did the battery pull (it took about 20 tries) and the phone doesn't turn on, no led or anything. Will htc know it's rooted regardless?
[EVO 4G Q&A, Help & Troubleshooting] cutthroatamft:
You should be fine to send it to HTC, my friend has gotten two replaced that exact way. He had no issues with them finding out his were rooted.

[EVO 4G Q&A, Help & Troubleshooting] antwizot:
Thank you cutthroatamft for the instructions on dealing with this. I also am in a boot loop with no recovery after some nv misfortunes. I formatted the sd card to fat32 and compied the pc36img.zip to it. After turning the phone on it did find the file and read it. Not sure if it worked or not as it did not reboot. I am on hboot 2.10 but I was on that before. I followed the rest of the steps (my computer does see the phone) but when it came to the "fastboot delete nv" I got the following message "FAILED (remote: not allowed)". I tried a couple other commands to be sure and got the same message. Thanks again for your help so far and any ideas would be greatly appreciated.
[EVO 4G Q&A, Help & Troubleshooting] cutthroatamft:
The hboot must be modified to allow remote commands. 2.10 is newer and the option to fastboot was removed. The one I included is a spoofed 2.10 that allows fastboot commands, normally you can't downgrade. Keep trying to get it to see the file, try a different SD and/or use a memory card reader if you can.

Erasing the NV items shouldn't be possible, only overwriting them. It shouldn't take hours. Perhaps try the steps again.

If you read this thread and the write up you would be highly aware that my method has indeed "unbricked" numerous devices.

From the looks of your quote I actually assisted someone whom wanted to brick their device. I understand your perception of the situation may be a bit different but I have had extensive conversations with all the people in the thread who try my method. I have never heard from any of them that my write up was in any way malicious. I invite you to look again at the situation before you make such harsh judgements. On a side note the Evo I'm using to respond was fixed with the above method. :p

I tried your method but the spoofed Hboot file gets flashed in a sec (Maybe it is not getting flashed) but Hboot comes as 2.10.0.0.1

Phone connects in fastboot (At times My HTC comes in win7 and at times it shows HTC Bootloader but fastboot devices the devices shows up) Only fastboot erase userdata works and in others I get error "FAILED (remote: not allowed)"

That readme is awesome. I'm putting it on my SDCard just in case I ever need it for some reason.
[EVO 4G Q&A, Help & Troubleshooting] HipKat:
I can't say they WON'T check, but there are multiple posts on here and on SDX from people who sent their phone in via mail on a replacement with S-off and no one ever said a word about it.

I believe that broken, bricked and otherwise damaged phones sent in are probably ripped apart and recycled, or just trashed.

Even for people going to the Sprint Store looking for a replacement, I've seen very VERY few accounts of them getting caught with S-off.

Not that I endorse telling people on a public forum how to defraud their insurance, but wth, if you're worried, brick the hell out of it, crush the screen, run it over, kick it through a wall, whatever it takes, I guess.....

[EVO 4G Q&A, Help & Troubleshooting] rymiwe:
I'm also experiencing this, but I'm afraid I've been less successful, even after following each step of the readme.

I did a full format (FAT32) of the SD card from my PC to start.

Then I flashed the 2.10 spoofed HBOOT. That got me somewhere! From there I could execute the "fastboot erase" and "fastboot flash" commands, though erase failed for nv, microp, and radio:

FAILED (remote: partition is not allowed to be erased!)

Everything else succeeded.

From there I ran the RUU which brought my HBOOT back to 0.79.0000, or so it says.

However, there were no improvements in my ability to boot to recovery or the full OS. I also tried flashing the PC36IMG version of recovery, but I'm still getting the same behavior. :confused:
[EVO 4G Q&A, Help & Troubleshooting] cutthroatamft:
Did you execute "Fastboot flash nv nv.img"?

I wasn't able to verify the working commands as I wrote the readme as an afterthought to fixing my Evo. I don't have another Evo or I would rebrick and fix it so I could just make a .bat file to run the commands for you.

The NV partition must be replaced with the one included in order for the phone to be successfully repaired. Start by reflashing the spoofed Hboot and follow the steps again. If you could write down the successful commands I will edit and repost the readme with a .bat file.
[EVO 4G Q&A, Help & Troubleshooting] rymiwe:
Sure, here's what I ran, in the order you listed out the partitions:

C:\EVO_Softbrick\EVO\ADB>fastboot erase nv

erasing 'nv'... FAILED (remote: partition is not allowed to be erased!)

finished. total time: 0.001s

C:\EVO_Softbrick\EVO\ADB>fastboot erase userdata

erasing 'userdata'... OKAY [ 5.155s]

finished. total time: 5.155s

C:\EVO_Softbrick\EVO\ADB>fastboot erase system

erasing 'system'... OKAY [ 4.246s]

finished. total time: 4.246s

C:\EVO_Softbrick\EVO\ADB>fastboot erase recovery

erasing 'recovery'... OKAY [ 0.061s]

finished. total time: 0.061s

C:\EVO_Softbrick\EVO\ADB>fastboot erase microp

erasing 'microp'... FAILED (remote: partition is not allowed to be erased!)

finished. total time: 0.001s

C:\EVO_Softbrick\EVO\ADB>fastboot erase boot

erasing 'boot'... OKAY [ 0.031s]

finished. total time: 0.031s

C:\EVO_Softbrick\EVO\ADB>fastboot erase radio

erasing 'radio'... FAILED (remote: partition is not allowed to be erased!)

finished. total time: 0.001s

C:\EVO_Softbrick\EVO\ADB>fastboot flash nv nv.img

sending 'nv' (640 KB)... OKAY [ 0.333s]

writing 'nv'... OKAY [ 3.103s]

finished. total time: 3.436s

So, userdata, system, recovery, and boot were erasable. Also, as you can see at the bottom, I did flash the nv image.
[EVO 4G Q&A, Help & Troubleshooting] skyfolly:
been there done that, i had it sent back to vendor to fix it, anyways, it is damn solid right now, even maybe a hundred flashes so far.........
[EVO 4G Q&A, Help & Troubleshooting] rymiwe:
You sent your phone to Sprint or to HTC? Did you have insurance? Was it still under warranty? Did you somehow get it back to S-ON before sending it back?

You say it's "damn solid" now - you got the same phone back and they were able to fix it? What ROM were you running when the issue occurred? Did you make a mistake and flash something incorrectly or did the problem start to occur seemingly at random? There have been many cases of people experiencing boot looping several days after flashing CM7 and after not having flashed anything else since, as in my case.
[EVO 4G Q&A, Help & Troubleshooting] cutthroatamft:
Rymiwe I can say that my method has yet to be successful on a cm7 bootloop. My writeup is intended for people that have corrupted nv items. Unfortunately I haven't been able to come up with a fix for the cm7 issue. I run a stock Rom on my Evo due to instability and possible issues from anything custom. Also I'd like to add that HTC announced recently that all phones will start shipping with unlocked bootloaders (s-off) so its very likely you won't have any issues sending it to HTC for repair. I hope you find a solution to your issue however I don't think anyone has come to a conclusion on just what causes the cm7 bootloop. Best of luck.

[EVO 4G Q&A, Help & Troubleshooting] cutthroatamft:
S-on

Okay, being S-on my method will not help you in any way. You must first be S-off in order for the spoofed hboot to flash. I would recommend sending your device to HTC if it has NV errors as I am unaware of a method to S-off your device once it is unable to boot.

Always, ALWAYS S-off your phone before messing with it's file system in any way. This ensures you have access to recovery and fastboot commands that could save your device from being a paperweight. Not to mention EVERYONE suggests that you make a backup of your phone before attempting to change anything about it's file system.

I made a .qcn backup of my device as well as a backup through recovery before I ever changed anything about it. This ensures if I ever make a mistake I can revert. Is anyone aware of a way to enable download mode on an Evo?

Your instructions changed my symptoms. At first i would boot loop on the white splash screen whether i regularly booted or attempted to use recovery. After your procedure i now boot to white screen then it goes black with 5 buzzes (like it is a hacker laughing at me) and just stays there. I suspect it is because i had been following DECK and was up to 1.3d but i think he follows CM7. Figured it couldn't hurt. One thing to note. On a laptop not hooked up to the internet, i tried to use the supplied driver for my win7 machine and to update android1.0 and it didnt work. on a laptop hooked up to the internet, the laptop downloaded the driver from the internet.
