HOW TO PROPERLY FLASH A JB ROM

Ok so first thing. We have all see a rise in questions how to properly flash a JB ROM or JB modem. some people say one way other say another. Which kernel/recovery do you use? which is the best way to flash a modem? Why use "X" over "Y"? Here is a small collection of what I use that has never failed me. If you follow these steps you can't go wrong.

1)

If you have never been on JB before. you need to flash a JB one click that wipes everything. even internal storage. I know its a bit scary to wipe your internal storage but it is necessary to repartition the phone. under JB we have a new /preload folder; which is ~200MBs. So we need to make room for it. You can grab a copy of GB27. Make sure to get the data wipe version. Back up all your internal storage on your PC before you flash.

How to Flash a Modem

Somethings have changed due to new recovery kernel for JB.

This is if you need to know how to flash a JB modem. Really, there are two ways to accomplish this. One is with PC odin and the other is flashing in a recovery. We will start with PC odin first. use the link below for where to get the modem.....JB modem. Download a JB modem which is FK23 - GB27. ll of them will work, some better than others. I recommend downloading a One-Click (OC) modem and while you are there download a Zip version as well.

Odin / PC

Once the OC odin is download open it up as administrator and put your phone in download mode. once you hook your phone up to the PC you will see a yellow [COM:] box. this means you are connected and ready. So now all you have to do is hit the start button. Let it run and finish......it will take about 3-5 mins. It will auto-reboot your phone when it is finished. Now all you have to do is update profile and PRL and your good.

Then when you are on that kernel:

Just reboot to recovery

Wipe cache and delvik cache

flash modem

reboot

update profile and PRL

If done properly you will have your baseband show the modem you flashed. You will have data now on a JB ROM. Just make sure to update profile and PRL once its booted up. Either one of these methods will work and you can flash different JB modems to see which one works better. For me personally, GB08 and GB27 modem works the best.

Flashing a custom ROM

The biggest thing is make sure to

follow the OP directions

. They will never steer you wrong. Now that you are booted up and everything works, make sure to update profile and PRL too, your phone is now ready to flash a JB ROM. Now, you will also have a JB modem now with the Full Jelly Bean ROM.

You are going to need a few things handy before you do so.

(Need to get rid of all data / system files / cache / delvik cache / preload folder)

Seems there are issues with flashing/wiping from agat's or garwynn's kernel/recovery. So, it is recommended to flash with EL26+CWM kernel or EL29 Direct Boot kernel.

EL26 download link : http://www.rwilco12.com/downloads.p...ls/Recovery Kernels/GB/Chris41g/Stock CWM/TAR

EL29 DB kernel

And then of course the ROM you wish to flash. that brings me to my next portion

when you download anything that you are going to flash.

Please check the MD5 Sum and make sure it matches what is posted

. I have seen countless issues due to flashing corrupt files. This way you won't have strange issues after you flash it. Ok now that you have the ROM you want......let's flash it.

General steps

(actual steps may vary. Always read and follow the OP directions)

1)Reboot to safe recovery

2)wipe cache and delvik cache

3)navigate to install zip from SD Card

4)Flash JB wipe all 2x zip

5)Flash the ROM

6)when it is done....reboot....be patient

That wasn't that painful was it? those steps never failed me. Please if you have issues make sure to follow this. If you are having issues and you followed this to the letter, I will be more than willing to help you.

But

If you decided to do your own thing and not read....well, that's on you then. TBSGS3/4 has been downloaded over

4000

times and there has only been a handful of issues. Mostly due to people not reading/following the install directions or coming right from ICS or not having the correct modem.

And remember.......Always follow the OP.

I hope this helps and I am open to corrections/addition to this post. I don't have all the answers but this is a community. We help each other, We learn and we grow. :)
