New baseband

Does it matter if I upgrade to the new baseband before or after installing Cyanogenmod?

it doesn't matter. the upgrade will revert your ROM to stock & locked either way. You'll need to use the jcase_rootme zip file to get root back after you upgrade to the new baseband. Should be able to find it on here or on android central. I can't remember but I think both forums have links to it.

You want to do it before. The update will revert you back to total stock. Then you need to root and install a custom recovery again. To update to the ZV9 Go here: http://androidforums.com/optimus-v-all-things-root/563443-guide-how-flash-zv9-update-step-step.html
To Root and install a custom recovery in one fell swoop, go here: http://androidforums.com/optimus-v-all-things-root/531810-rooting.html
Don't forget to make a backup of your system in the custom recovery before you try your hand at installing a custom ROM.

Wrong section. You should ask in Q&A

Sorry for the of topic.
Is there a difference between the 3, or a reason to updating the baseband?

If you say you have no ROM installed, then it means you do not have a working phone. Your only option, therefore, is indeed to download a stock ROM and flash via Odin or (custom) recovery. Whichever option you choose, you would need to make sure that you download and flash a compatible ROM, i.e. one that would not brick your phone. Your best bet would be to revert to the same Android version you were on prior to the ROM being uninstalled.

Does installing a TWRP Backup also affect phone Firmware?

Hello guys,
following situation:
Long time I had a 4.4.something Rom installed. Before I flashed a custom Lollipop rom, I followed the advice to just go back to stock and let it update to Lollipop so that the firmware will be updated accordingly and I won't run into problems when flashing a Lollipop Custom Rom. Everything worked fine. Now I had to send my phone to HTC for display repair and just to make sure they won't nag about the custom Rom I reflashed some older stock rom via TWRP backup I found here, I think it was a 4.0 or so. The question is, does this also affect my phones firmware or is it still on the current newest level? So when I get it back, would I need to update to stock Lollipop again before flashing a custom rom or can I go for it straight away?

It won't affect your firmware.

Okay thanks, so Firmware should still be up to date and I can flash a Lollipop Custom Rom. I don't know what they do at HTC repair, if they only reset it or if they also update it, well I'll see.

How to switch ROM? From Lollipop back to stock, help!

I am running stock right now (JB 4.2.2) and I am planning to flash a Lollipop ROM (AICP 10). If I create a backup (for my stock ROM) at TWRP and did the needed measures to flash the Lollipop ROM and was successful however I want to return to stock ROM. Do I just have to factory reset and restore my stock ROM backup to have a stock ROM again? Sorry for this noob question.

Heeeeelp!
Any idea if that would work?

Just use odin to flash any stock rom

So backup-ing in TWRP before I flash Lollipop from my current rom [Stock JB 4.2.2] is useless?

You can also use your backup from TWRP.
But It will then show that it has been modified, could be a problem with the warranty.
If you want to go back completely for warranty then odin is the way to go

Thank you! I actually don't care about warranty since mine is overdue already. All I wanted to know was if I will be able to go back to JB 4.2.2 with that backup in case I have problems with Lollipop.

Need stock lollipop rom for rooted T800

I want to install a stock lollipop rom that has nothing changed because I may have deleted some system apks that are needed for the Default App manager to work. I want to get everything back to normal as possible and then reinstall a custom rom. I am rooted and have twrp installed. I do not want to lose rooted or twrp if possible.
