[Q] Flashing stock firmware via TWRP

I am currently using CM10 Rom with Marmite kernel 8.3+
Performane wise it is good, but battery has been a big problem for me, as the stock 4.1.1 sojuk was way good in battery performance..
My phone has TWRP recovery and I have the official stock .zip file for my phone (Nexus S M200)...
The question is that flashing firmware via recovery is recommended or not? Will i brick my phone or what? Will my phone work perfect after flashing stock firmware via twrp? I dont want to use the fastboot method pls...
Need the answers fast

Can you please get a link to the post, as I wasnt able to search it...
Though, I found the official stock rom in .zip format (100% confirmed)... should I use this ROM for flashing? Loosing recovery or root doesnt matter... i can get that back anytime...

Just flash it via TWRP if that's more convenient for you.

So yea, that question and that answer is sufficient for you to calm down and JUST FLASH IT. :good:

One you buy the Franco Kernel updater app, back up the stock kernel, and then flash Franco. In the case you didn't back up your kernel, you can go to the stock kernel - http://forum.xda-developers.com/showthread.php?t=2518816 and flash the zip in recovery.

I would re-flash the recovery and the cache.img. If that doesn't work, try another recovery like TWRP or CWM and see if it works there. If that doesn't work, try flashing the factory image.
from my experience the nexus 5 dosen't support mounting via recovery..

Not to a PC, no, but he means mount the /data partition so the phone can write to it.

So you dont want me to help? I give you the answer and you throw it back in my face?
...and yes, you should know how to fastboot flash any partition before rooting. Its in the "read this before rooting" thread stuck at the top of this forum. If someone tells you to flash a cache.img - you should no what that means. If someone then tells you how to do it, you shouldn't come back with ridiculous comments.
Some people aren't worth helping. You'll receive nothing from me again.
No I wouldn't have replied in the s4 forum. I had an s3 and I would have replied like this too. You're supposed to arm yourself with basic knowledge before rooting. Everyone here is sick and tired of helping people who can't be bothered reading sticky threads.

Man I do appreciate the help but like I said I do know how to fastboot I was not asking how,just which file to use. I understand people get tired but is someone not allowed to overlook or just plain old,have a bad day.I am no newbie I've helped plenty of people with their s4's,evo3d and other phones hence why I have 6,0000 thanks.everything was going wrong yesterday and for some reason the simplist stuff was hard.But anyways sorry if I said something I shouldn't have,I just hate when you guys think everyone asking for advice or help was a noob

[Q] Does reinstalling the kernel reset the dalvik/bionic caches?

Hi,
Does reinstalling a rom reset the dalvik/bionic caches and adreno drivers?
Because I change my rom a lot, and I don't want to reflash the other zips everytime I change my kernel.
Cheers,
Sir Zeph

Hi,
Yes, you need to reflash them (Adreno drivers, Dalvik and Bionic patches) each time you flash a rom, they are overwritten even with a dirty flash. Unless your future rom include them.
When you flash a kernel no it's not necessary, they are not on the kernel side.
