At the end of the "effen manual" in ace's hack kit, it shows you how to reflash the stock radio and rom, probably in case you ever need to send the phone back for insurance purposes. My question is...do I need to reflash the stock radio if I intend to use the stock radio with a custom rom or will the stock radio still be in tact after rooting, downgrading the rom, etc...
In other words, does ace's hack kit affect the stock radio?
Yes. As part of the downgrade step, the radio is also replaced by the one in the downgrade package.
Thank you.
I will reflash the stock radio and then flash a custom rom. It doesn't matter which order I perform those two steps in...or does it?
if your going to flash a custom rom, go ahead and wait to flash the radio, until you flash the custom rom, then you can flash the recommended radio for the rom.
Like said above because sometimes the roms will run just as good with one radio as they do with another. I did though when I used the kit.... can't really go wrong with either one you can always change it later.

The first rom I flashed after I rooted with the Hack-Kit was the rooted stock rom with the OTA update in PD98IMG.zip form (http://forum.xda-developers.com/showthread.php?t=1058042). Because it has the OTAed stock radio with the rooted stock rom in it so everything is done in one step (installed from HBoot). After that you can flash any rom of your choice from recovery and you get to keep the OTAed stock radio.
QUick question
When flashing a radio, I install the file on root and from Hboot screen I choose update and it will be flashed?
Is there a way to stop the phone from rebooting and go into recovery and flash a new rom after wiping data.(this is the preferred method for flashing ROMs on the thunderbolt? clockwork recovery and not from hboot correct?
This S on/off? whats the dealio ?
Maybe agood link to flashing radios
Thanks PR
okay my friend told me that i need to install a custom recovery after i flash a new firmware. but everything i am reading about 3.32 says that i only need to flash new firmware. delete the img file off root and flash new rom. Is the custom recovery already unlocked? am i going to need to use ADB to install the new rom or 4ext? thanks for your feed back
I am S off
Rooted
I have super CID
and i am currently on 3.24 firmware

Do you have 4ext recovery already installed ???
yeah i already have 4 ext installed right now. but i don't know if i am going to have to reinstall it after i flash 3.32 am i going to have to use ADB? or am i good just flashing firmware and then flashing rom like regular?

You will not have to flash a new recovery after flashing the new firmware Mac... but I do think that when you go the flash a new custom rom from here I would wipe the phone (ie) super wipe or use the builtin one in 4ext under (wipe and format) use wipe everything but SDcard.....
Thank you for the help and patience. Much abliged.

no problem, just one thing, if you have super wipe only use it with sense roms not AOSP roms, and if you are using any of the new sense 4 roms like OrDroid or Insertcoin that is builtin the rom when you install too, just read everything very carefully because of the installer (ie) Aroma installler.....
Just as the title states...Do anyone know if you have to flash the boot.img file separately every time I flash a custom rom or is it with certain roms only?

as mentioned in other threads.. if you are flashing similar ROMs ( having same kernel ).. there is no need to flash boot.img separately. But say if you wanna switch from sense to aosp you must do that as they have different kernels.
Again if you are just upgrading from older version to newer version of same ROM and if there are no kernel changes no need to flash it
To clarify, flashing the boot image from fastboot is only necessary if you are on hboot 1.14 b(coming from AT&T firmware 2.20). Previous hboot versions, the kernel is flashed automatically when you flash the ROM.
I am about to flash my nexus 5 device.
I was wondering.. if i unlock the bootloader and install a custom recovery plus create a backup.. that means ill have basicly a backup on my phone of a factory ROM and kernel right ?
So If i play around with custom roms and Kernels does that mean if I want to go back to stock kernel or/and ROM I can just recover my backup files from ,for example, CWM ?
And also if anyone here knows... how big difference can a kernel for battery life extension make ?
Then..
If I want to flash both.. Custom ROM and Kernel.. Rom comes first ? And if after that .. lets say I have flashed Cyanogenmod , and I have decided to change ROMs , Do I have to flash factory ROM ? Or I can just factory reset and Flash ir over the Cyanogenmod ?
For example.. for elementalX kernel I read this line... "You should only flash ElementalX over the kernel that came with your ROM!!!" I assume that means I do flash the ROM first... and what if I want to change Kernels later on? I re-flash the factory kernel ? And how do I do that?
For now that would be it
Thanks
Yes, installing a custom recovery (I recommend TWRP) allows you to create a backup of the existing ROM for restoration at a later point in time if you don't like the phone's existing ROM. Restoring TWRP backups have always worked except for me except in a couple of situations where I could not boot the restored ROM without first doing a factory wipe of the data and cache partitions.
I can't comment on custom kernels except to say that everyone uses their phone in different ways and getting the best battery life and performance may require a lot of tweaking. You could just try different kernels to see which one suits your needs.
You can restore the ROM's original kernel by extracting the kernel from the original ROM and flashing it. Alternatively, you could dirty flash the over the existing ROM. For example, if you are running CM12.1 2015-12-30 with a custom kernel and you want to go back to CM12.1 2015-12-30 without the custom kernel, you could just re-flash the entire CM12.1 2015-12-30 ROM again.

What advantages does TWRP has over CWM ? And also does it recover other files as well or just the system ones ?
And I guess its safer to just extract the original ROMs kernel.. Just how do i do that ?
TWRP is well supported and features a simple touch interface. TWRP will recover the system and data files.
Not necessarily safer to flash just the kernel rather than the entire ROM. It also saves time and effort because, if the kernel is not extracted and compiled for flashing in recovery, it could cause the phone to bootloop.
I've never extracted the kernel myself but this may help: https://www.youtube.com/watch?v=rLhprnOF6-U

So.. If, lets say, I flash cyanogenmod. Then Flash custom kernel. In order to change other kernel which is also custom , I should first flash the factory ROM which will have kernel on it ? And then reflash the ROM and then flash the new kernel ?
Im sorry , I also read a lot about this and somewhere on the way got really confused , haha.
Let's assume you flash CM version 1 and then you flash custom kernel "Kernel A". If you want to try another custom kernel named "Kernel B", you could just flash "Kernel B" over "Kernel A". If the developer of "Kernel B" cays it must be flashed over CM's original kernal, you could still flash "Kernel B" over "Kernel A" and hope it works. If it doesn't work, you could dirty flash CM version 1 over the existing ROM, then flash "Kernel B".

Thank you. Made things much clearer. Dirty flash means just flashing over the existing custom ROM and Kernel right?
And also.. What about if i have CM and Kernel B ... But i want to go change to ParanoidAndroid and still keep the Kernel B? This ROM would remove the Kernel and I would have to re flash ir right?
And also if I am just switching around ROMs only.. I can just flash them one over another? Perhaps a factory reset is healthy in between though.
Dirty flash means flashing over the existing ROM without wiping the system in recovery.
Flashing any ROM over an existing ROM will replace the system and kernel. If you want to change ROMs altogether, you'd flash PA and then flash Kernel B.
When changing ROMs, I always recommend a full wipe (i.e. system, data, cache).

Alright. And just one last thing that I got a bit confused of..
When I root and install a custom ROM, I am not going to receive OTAs. If I just flash the newest custom ROM does that work as an update? Or the newest ROM can ble flashed over the newest android? If so... How do I exactly get the newest updates manually? I have to flash to factory ROM and then somehow flash the update? By far thats how I understood it.

Depends on which rom, but updates to custom roms generally can just be flashed over. Not sure of the MM jump, but from KK to LP, it worked fine so far. Whatever you do read the instructions of the rom and kernel builders. You get lucky sometimes and can dirty flash things that should not be dirty flashed, but if there are issues, there are instructions on the rom or kernel page how to start again.
If you are factory modified and want a factory image you need to flash in fastboot. If on a custom rom, well, like I said follow their advice. Make sure to backup with recovery and save on computer before doing anything.
