I know folks are interested in doing this in order to get the new Radio, but is this really necessary for bringing the phone in to repair? I'm on the road most of the day today, and have a faulty headphone jack (which means it thinks there is a headset in all the time- PITA!) and won't have time to do this before bringing it in anyway.

With my HTC phones, I always just threw a stock rom on there so that a hard reset would look the way it should and no one seemed to care about the bootloader.
If my phone is repairable, I'd rather not go through the hassle of doing this just to re-install everything when I get back. If its not repairable, they'll issue me a replacement and I'll have to do this either way, but on the off-chance they can fix it quickly, what do you guys think?

I'd like to go ahead and say that Sprint reps probably won't notice the custom recovery, and if they do they probably won't care. In that case, I'm thinking I should just back everything up with Titanium, and then go into settings and hit upgrade FW, right? Technically this should all be possible OTA, if I understand correctly?

Has anyone had any experiences otherwise that I should know about?

Depends on your store I would say. Rooting voids the warranty so to beware I'd back up everything and kp500 CD. Its the fastest way to get to a sprint approved state where they can't deny your phone's repair. I have really bad luck, if I were to try it as you were now they would undoubtedly deny my repair and put a note on my account so even if I went back to stock they'd never touch my phone again. That's worst case if you can risk that, go see them now. If not wait till you stock again.

I have an LG Optimus S that I rooted and it worked great! However, I need to switch it out due to a broken home key. I used these instructions to try and un-root it... and I followed the instructions and now my phone will not boot up. It goes straight to the custom recovery screen. I have tried to use nand restore to use a backup, tried to flash the thundeROM again and nothing is working. It boots to the custom recovery screen everytime. Anyone have any ideas? Thanks in advance for your help and time. I have tried the method using the emergency mode... but it didn't seem to take either. It couldn't get past the analysis part of the process.

In the custom recovery go to mounts and mount system flash a recovery again, shouldn't matter if its thinderc or xionia then flash any Tom compatible with v8/v9 radio, TR1.6 is, try rebooting then. Two things to add mounts may be under the advanced menu, and to be safe mount everything except USB.

No access to a computer...

Can this be done on the phone via android terminal instead of using adb? If so what changes are made to the commands?

Thanks.
 
Got to a computer but I am getting error writing recovery Permission denied on step: 11

UPDATED:
I was able to run this command thru the android terminal successfully and continue on... Running V9 update now. Should I update to VC or VD? Not sure what i should do, any ideas? Whats better?

As the phone is stock right now should i just receive the OTA Updates?

If you are going to update at all you should probably go to ZVD. The only downside is the builtin hotspot got removed between ZVC and ZVD. You can get around that with a custom ROM.

Do not accept the OTA updates. They'll just force you to need to revert again to get root.

I'm of assuming you want to have the phone rooted. If not, then you can just accept the OTA updates.
 
Is there a benefit of going to VD? I have been using V9.

Also sense i just returned to stock using this method - I no longer have root right now correct? so i could just do the OTA to VD if I decided?

I do want root just want to see what version I should be on before i root this time around.

Thanks.

You are correct, if you reverted to stock, then you don't have root anymore, unless you meant privacy->reset (which I don't think you mean). The latter doesn't affect root.

If you accept the OTA ZVC or ZVD updates, you won't be able to root directly. You'll need to revert to ZV9 first.

Follow the ZVD stickied rooting thread and pretend you already did the revert step.

ZV9 builtin wireless hotspot works, direct rooting works, SD card unmount problem for some cards
ZVC+ kills direct rooting
ZVC+ fixes SD card
ZVC+ works with new LCD
ZVD+ kills builtin wireless hotspot, unless you root and install custom rom
ZVD+ adds Sprint ID bypass

I am thinking i will keep it as it was on the V9. Is there a way when i am rooted to stop it from telling me about the update?, without using a custom ROM.

When the prompt comes up, press more info, then pull your battery.
