FakeCID Automatic Unlock Failed
Here's a screenshot. I don't know if the failure to write the files to the SD card caused the failure. Did I miss anything on setting this up? I exited the script rather than do a factory reset. I saw the note about doing a factory reset and then trying again, but if this is related to the file write failure, I'd rather not reset the phone and have to set it all back up again.

I assume you're working on getting s-off. Working from that I expect you have the most recent update from almost a year ago. If you do then this thread should get you to where you want to go.

No. I am working on unlocking the bootloader so I can install a custom recovery. Hence the thread title. Is S-Off a requirement to unlocking the boot loader? I didn't see anything that says it is.

---

S-off makes installing ROMs easier because you don't need to extract the boot.IMG each time. S-off gives you more options but opens you up to a little more risk of you mess up. Read a bit more on the differences between an unlocked bootloader and s-off. If I can find a few links I'll as then tomorrow to help you out.

Thanks. I have done some reading and I am reasonably familiar with S-OFF. I think my problem is that I need to factory reset the phone before I try the bootloader unlock. The HTCDev site doesn't support this phone for a bootloader unlock. I'm not quite ready to do a factory reset yet so I will wait a bit longer.

---

Installing a custom ROM will require a factory reset, so when you're ready for that go for it. An app like this https://play.google.com/store/apps/details?id=com.koushikdutta.backup makes the transition much easier.

Ok I believe I know why the unlock is failing. My sdcard for some reason is getting mounted as read only, or at least the script thinks it is.
This is from the script:
Code:
db shell "dd if=/dev/block/mmcblk0p4 of=/sdcard/mmcblk0p4"
and line that tries to dump the mcblk0p4 file to the sdcard to pull it to the PC fails. I thought that the error I was getting was related to backups. this page:
http://forum.xda-developers.com/showthread.php?t=1986346
says that you need to remove mmcblk0p4 from the directory if you run the script multiple times.
So it appears that after the 'adb restore fakebackup.ab' command is run, at least on this phone the sdcard is mounted as read-only. Is there a way around this? can adb push/pull the file from phone storage directly to and from my PC if I want to edit the file manually?
Or, does anybody have a backed up modified file for this phone that they can send me? I am stuck at dumping the file to the sdcard so that I can modify it, but I think I can push a modified file to the phone so that I can then go to HTCDev to get it unlocked

An update. I followed the manual steps and was able to get the file with the CID in it off the phone. I edited it as per the directions, then pushed it back to the phone and used dd to push it back to /dev/block however after I rebooted the phone and did the readcid command, it still has the stock Verizon CID. Any help?

---

One last update, I tried both the manual method and the automatied script after factory resetting the phone. That did not work either. Any suggestions? I'd really like to get this phone rooted if I can. If it helps or matters, my phone device type starts with an FA, not the HT that the script calls out.
The script works up to the point that I run the dd command to write the modified file back to /block. The dd command works, but checking the OEMCID it is still the Verizon CID. Do I need to S_OFF the phone first? I didn't think that was related to this.

After reading the thread, I am not sure why you wouldn't just go with s-off instead of only unlocking the bootloader. Yes, there's more risk in having an s-off phone, but it does make life much easier overall. However, If you are able to s-off the phone, you're done - no need to further work on unlocking the bootloader because the phone is fully unlocked (and it will stay that way unless you explicitly lock it). It also seems as though the s-off methods are now more tried and true for this phone versus just unlocking the bootloader.
Instead of continuing to struggle to just unlock the bootloader, you may try just going full out s-off. Just back up what you can - contacts to Google Contacts, USB cable to pull off your files/music/whatever to your PC, etc. then go for it. Make sure you are using the s-off method that matches your phone's current version.
Good luck!

thanks for confirming that. I misunderstood what S_OFF did, else I might have done it sooner. I did not realize that it also unlocks the phone as a whole. I thought it gave access to the radios, etc which I wasn't necessarily interested in.

Yep. S-Off is the full unlock. Once achieved, you can do whatever you want to the phone, including updating the radio (be very careful!), install a custom recovery, install a new kernel (from the SD card), install full ROMs without needing to push anything separately, mess with partitions, etc. IMHO it is the best way to go, but just be careful after achieving s-off, one wrong keystroke or click while connected to your PC, you can very easily make yourself an expensive paper weight.
Also, if you are installing custom ROMs, on this phone it does make a difference which recovery is installed. ViperLTE will not install properly with a CWM variant, but installs just fine with TWRP.

---

Success!!! many thanks to wmuflyer for pointing me to rumrunner for S_OFF. the phone is now S_OFF and the bootloader is unlocked. thanks for all the suggestions.

Congratulations. Now the fun begins. And remember you can always use the thanks button.
