stupid question, but no one will answer it - EVO 4G Q&A, Help & Troubleshooting

or acknowledge that i'm asking a question, so without further ado
i want to flash the kernel to fix the 30fps cap on the novatek panel, but i don't want to do it without a way to fix it encase i want to get rid of it. i believe it's the stock boot.img i need but where do i find it and how do i flash it.
again sorry for the stupid question.

Flash whatever you want. Running any of the three RUU files will restore everything on your phone to stock unrooted and make it returnable.
If you flash the latest RUU, you won't be able to every root again (for now), so be sure you are returning it in that case.

Take a nandroid backup before flashing the new kernel. If you don't like the changes, restore your backup.

[Q] Broken 4g...need to exchange

So I was one of the unfortunate ones who had their 4g totally hosed. I am going to flash a stock ROM to make it look stock and take it into Sprint.
My questions are as follows:
If I flash a stock non-rooted ROM will it break my custom recovery? This leads to my next question, which is can I flash back via a Nandroid backup if Sprint tells me to take a hike?
Thanks in advance!
You may want to follow some of the unroot threads in the dev section... You can flash another rom but more than likely you will have s-off in your recovery. If sprint wants to be d-bags they will still find out you are rooted. I would nandroid, copy the nandroid folder to your PC (and anything else ROOT related on the SDcard), wipe the phone/sd card and follow the un root methods.
I'm in the same boat. Just curious, what are you planning on telling them happened to your phone?

How do I back up my stock recovery?

US Cellular has been promising Froyo for the CDMA Desire since October, and I'm tired of waiting so I'm going to root it and flash a Froyo ROM myself. I read through the unrEVOked documentation, and it mentions that if I want to install official updates in the future I need to restore the recovery image, but it doesn't tell me how to get it. How do I pull the stock recovery image from my phone so that I can flash it back on should I need to?
You can't actually backup a whole rom without rooting first. You need the custom recovery to do a nandroid backup which will back up the whole rom. If anything does go wrong or you need to reinstall then you can just use an RUU to do it. US Cellular doesn't have an RUU yet but you can use other CDMA RUU's.
So am I to understand that there is no way to back up the stock recovery, as I would have to overwrite the existing recovery just to do backups in the first place?
Yep, root access is needed to back the whole ROM up
To be honest, it's better with root anyway and a lot better when you install a custom rom.... from my experience anyway.

[Q] Guide to downgrade r8000x to 2.3.3?

Hi I'm having trouble finding a good guide to downgrade my Verizon Xperia play from version 2.3.4 to 2.3.3 so that I may root my phone.
Does anyone know of one, that I may use?
Thank you.
Watch this video. It worked for me and is the only known way to downgrade and root.

Sent from my R800x (that's eventually gonna get root & an unlocked bootloader)
Also a little tip: To make things much easier on yourself, before you go back to an ICS ROM (or whatever), make a nandroid. You can just flash another GB kernel when you want to go back and then restore the nandroid. Makes switching much, much easier.

He can't make a nandroid to downgrade because he needs to downgrade in order to root. Without root, he doesn't have a custom recovery in able to make a nandroid backup

[Q] Returning to Stock

I basically want to have nandroid backup of the stock ROM, so I was wondering if this was doable...
http://forum.xda-developers.com/showthread.php?t=1433101
Could I run this and still have a custom recovery? Or would it overwrite my recovery with whatever stock has? I don't remember... I plan to run all of the OTA updates and everything in order to have this nandroid backup if/when I need to take my phone into Sprint.

[Q] Kernel install

I apologize if this has been addressed before. I did the prerequisite search and couldn't find a straight answer. I am new to flashing kernels and want to install one, specifically Faux123's for stock TW roms. Before I go down that rabbit hole, I want to make sure that if, at a later date, I ODIN back to stock to get my phone back to "day 1" with a factory reset, that the custom kernel will be gone and overwritten with the stock one. I don't want to make any changes that I can't easily undo. Thanks in advance.

Yes, flashing stock will overwrite w/e ROM/kernel (and root if you flash non-root stock).
