FAILED (remote: 12 signature verify fail)

I tried to flash new firmware using the instructions from http://forum.xda-developers.com/show....php?t=2696282 but it doesn't work. It says it's failed; I've done it numerous times to no success. How do I update my HTC__622 to version 3.xx.xx? I checked MD5 file and it says its correct. I used the file from this forum http://forum.xda-developers.com/showthread.php?t=2696514, but it still doesn't work. I'm trying to update my firmware so I can use the latest sense roms

Since you don't really understand how to update firmware manually ...
Why don't you do the easiest way ?
http://forum.xda-developers.com/showpost.php?p=56544097&postcount=2736
1. Install TWRP recovery
2. Restore 2.11.708.2 nandroid backup (you can select only system and boot if you want to keep your data)
3. Flash stock recovery
4. reboot and check for OTA, let the system install OTA to 3.32.708.4
5. reinstall TWRP or any custom recovery
6. install any Sense custom ROM that you like
7.done

Just another thing, do I need to lock bootloader and then unlock later on? Do I keep my root? Or do I have to root it again?
Sorry, I got so excited :fingers-crossed: finally gonna get some lovin' from the other sense custom roms! <3
Lastly, will my root be gone when I restore this? Will my phone brick if I update it to OTA after the flashing of the zip?
Sorry again if I got too many questions! I've been dying to find a way for this

No need to relock bootloader ... never do that.
You will lose root but you can easily re-root.
You don't flash the zip ... you need to extract the zip on your PC and transfer the contents to your device TWRP/BACKUPS/yourserialno/thisfolder
Restoring a nandroid backup will not brick your device.
Furthermore, your intention is to flash the latest Sense custom ROM after your firmware is updated to 3.32.708.4 and those custom ROMs come pre-rooted, so no need to manually root it.

Thanks a lot! Finally someone giving me answers I couldn't find :cyclops:
Oh, and if at some point in the future that I wanna try out the lollipop roms such as Skydragon, do I need to update firmware? Is the firmware in that rom different from the ones in sense roms? In other words, will I encounter problems if I flash a GPE Lollipop rom?

You can install GPE 5.0 SkyDragon on your 3.32.708.4 firmware but not on lower version like 2.11.708.2
The only problem you may have is WiFi disconnected when screen-off but to some including me, this is not happening ... only for some people on some firmware.

If you are S-On you will need to re-lock your bootloader for the OTAs, If you are S-Off there is no reason to re-lock.

That was what I've been told, and have also read on other sites. For example.
Personally, I never worry about OTAs. Being s-off and flashing firmware is a lot quicker than waiting on my carrier to update.
But thanks for clearing that up for me.

That's for manual updating via the ota zip. The thing i ment was official ota via update menu inside OS with stock recovery.

[Q] How tell if Developer Edition is now Retail Version?

My developer edition starting doing boot loops so I odined the stock restore version in https://www.androidfilehost.com/?fid=95857557620392097
and got the phone back to working. However, I am not able to odin TWRP. If I somehow lost my unlocked bootloader in the DE, how do I know for sure?
Titanium Backup nor Superuser will not work?

Boot into download mode and see if you get "Mode: Developer". If you don't see that then there is a good chance your bootloader has been locked. The only way to recover from a locked bootloader at this point is to flash the aboot backup, if you did an aboot backup.
Titanium Backup will not work unless you are rooted and you can't flash SuperSU unless you have custom recovery (TWRP) if that is the way you're trying to flash SuperSU.
Did you do the aboot backup as strongly recommended in a number of DE threads?

How can I tell if I have the developer edition?

Did you buy a developer edition phone directly from Samsung? Or someone might be selling one they bought from there. Anyway, they can only be got from Samsung for full price. Also pull the battery and it has "Developer Device" written there. Or use the method found in the post directly above yours.

Thanks

Make a Nandroid Backup?

Am i missing something here? I am under the impression that the only way to make a nandroid is with a custom recovery installed?

46 views and no replies...helpful

Answer. As far as i see yes you need a custom recovery unless you know how to pull out the current rom and make it into a kdz or other recovery format. Dont ask me how to do it cause i do t know. If u mess up your phone. Kdz s the only thing u have unless u really bricked ur phone

The app "Online Nandroid" coupled with its partner app "Nandroid Manager" works. It's not the same as a nandroid via a custom recovery however. If something goes wrong you'll still have to use a kdz or tot method to get things fixed but once you're up and running again these apps will restore your entire system. I can confirm it works as I have used it.

Is your ROM a custom ROM installed via custom recovery?

No, it's stock B13 that was flashed to rooted stock B13, then XPOSED framework installed by Flashfire v .24. This is verizon. There is no custom recovery option, nor is there an unlocked bootloader. You said, "If something goes wrong you'll still have to use a kdz or tot method to get things fixed but once you're up and running again these apps will restore your entire system. I can confirm it works as I have used it.."
By "entire system", do you mean you can flash your backup over the stock unrooted KDZ?

No. You have to have root first. Then you can restore everything as you had it.

Question on losing root after OTA

So op 5t released a new update, whenever i open the update screen it says root detected, i would lose my root privileges if I update the phone.
I wanted to know whether i would only lose my root, or entire thing of bootloader getting locked etc?
After updating will I be able to just boot into recovery and flash root file? Or whole process I would have to do again
Thanks

Updates reinstall the stock recovery. You have to flash twrp then root.

When you install an OTA it will NOT relock your bootloader, it will reinstall the stock recovery since that is included in the OTA zip and is forced installed to be sure the update installs correctly.
You will lose the root temporarily until you flash a custom recovery again and your root of choice.

Wait, really? https://github.com/topjohnwu/Magisk/blob/master/docs/tips.md#ota-installation-tips doesn't say anything about having to flash twrp again...
When an OTA is available, please go to Magisk Manager → Uninstall → Restore Images. Do not reboot immediately or you will have Magisk uninstalled. This will restore your boot (or dtbo if available) back to 100% untouched stock images in order to pass verifications. This step is required before doing any of the following steps written below!

Or does "100% stock images" mean the stock bootloader = flash twrp again?
Just to clearify, updating my phone by an OTA does not lock the bootloader but I'd have to flash twrp and magisk again..?

yee, but after you have used the OTA you will need to flash twrp again since the OTA flashes the stock recovery, or modify your boot image but that is a pain in the ass. :silly:

Means if I'd like to unroot my phone by doing nothing, this is probably the easiest way?
