Do I need to go back to stock?

Hey,
So since the OTA update has just been announced for EK02... if I am rooted on a custom ROM, do I need to go back to unrooted stock in order to receive it? Or should I just wait for someone to make a .tar of it? What are you guys doing with this news here now?

stock
mrush, I think it depends on how fast you want to get to EK02 to fix any LoS or hotspot issues (see notes on Sprint site). You can go back to stock and let the OTA proceed in the next 10 days (which means you will have Carrier IQ again - if you care). That's a negative for me. Otherwise, you can wait for the XDA developers to update their kernels and ROMs, which they will start to do, with the EK02 kernel and modem updates over the next few weeks (with Carrier IQ removed).

Ok thats wwhat I was thinking I would do. I do not want carrier IQ and I want to go straight to Calks version of ek02 but once they are able to pull the modem and get it put in place of EG31.

There is experimental Disabling of CIQ on EK02 w/o requiring a custom ROM flash here:
[ROOT][NCIQ][EG30/EG31/EK02] Auto root your existing stock ROM (w/o ODIN/ROM Flash)

I'll be waiting for a custom version, no spying on me!

On Calk 2.0 and EG30 modem and confused.
What exactly is the new update that Sprint is rolling out for the Epic 4G Touch? A new modem EK02? What about the stock rom itself? Some minor tweak? What if I had no LOS to start with?
I was on stock rom, and then rooted with shfub's method. I then install EG30+CWM so no change in my modem. I then backup and then flashed Calk 2.0 ROM. I did not do the new 2.01a zip which if I understand correctly, upgrades the modem to EK02. According to Calkulin, his 2.01a rom includes the following:
Based on rooted 2.3.6 / EK02
ROM includes:
Rogue kernel
Most Samsung apps
EStrongs File Explorer
HTC_IME mod keyboard
ICS keyboard
Wireless Tether
Busybox
and a couple more
Is Rogue kernel just stock kernel with custom recovery?
I flashed Calk 2.0 and this is what I have:
Android 2.3.6
Baseband version: s: D710.10 S.EG30 (so I still have the original stock modem?)
Kernel version: 2.6.35.7-SPH-D710.EK02-CL704398
Build number Calkulin's E4GT ROM v2.0
My questions are:
If I have no issue with LOS, do I need to install Calk 2.01a?
Will my phone automatically update to the new one that Sprint is pushing out?(assuming new modem and new stock rom)
Will I lose root or brick my phone if the phone does that?
Can I just flash an EK02 modem on top of my current Calk 2.0 or wipe everything and install Calk 2.01a if I want to upgrade to EK02 modem? I am not sure I want to do that unless 3G data speed is improve.
I thought I was clear on ROM packaging the kernel and modem together but now I see that you can have one ROM and flash different kernel and modem.
Please correct any of my misunderstanding above.
Thank You.

EK02 and Calkulin Rom

if you have a regular unrooted phone with Ek02 or a rooted phone with EK02 can you go to the calkulin rom for Ek02 without switching the modem ? i dont understand modems

Modems are independent from roms/kernels, you can mix and match as desired.

so do roms that say Ek02 mean they support EK02?

it means they are based off the EK02 release which is android 2.3.6., for modems/radio its the baseband version. You can mix and match ROM/radio for your best results based on location/signal/etc.

does this eg30 modem file mean i can update to ek02 and if I dont like it switch back to eg30? i read some people switched back but others are saying its not possible but most of those dates are older
so?
if i go to ek02 modem can i switch back if i get los to an eg30 and hope everything is fine again?
also is ek02 more advantageous? such as the calkulin rom based off ek02 or the unnamed rom based off ek02, i see positive reviews and am interested but run eg30 and I get los if i switch any kernels

Yes it does, you can change to any modem you like and flash different ones as well.

Flashing

If I'm on EK02, can I just flash a ROM that is EL26 or do I need to find radios and what not? Basically I am stock rooted (all I've done is rooted) and I have EK02. Can I just d-load and flash the TNz Blended ROM that is EL26 without doing anything else 1st.?? thanks

You're gonna need CWM (ClockworkMod) installed in order to flash ROM's. Easiest way is using sfhub's script to install CWM, how to do that here.
I just took a look at the TNz Blend, and it includes a kernel along with it, so once you have CWM, all you have to do is install that as per instructions and you'll be good to go. You can basically use any radio/Modem you want.... I'm running a EL29 based ROM, Rouge Kernel (TNz comes with the Rouge Kernel), and the EK02 modem, and it works just fine.
So install CWM recovery, then you can follow this how to video to install TNz, and you should be all set.

Ok, I already installed CWM when I rooted. I was just confused since it seems like EK02 can refer to the kernel, the modem and the latest update of android from Samsung... So when I flash TNz I'll end up with EL26 ROM, the Rouge kernel and still have the EK02 modem?... I'm fixing to jump in.. oh, and thanks for the link in your sig.. I rooted and installed CWM with his vids

You are correct, whichever rom you choose will come with a kernel (most recent being el29). The modem is flashed separately. If you don't have any reception issues, you don't really have to change your modem

Updating Rom, haven't updated EL29

So I don't keep up on my phone game like I should. I need to do this update to my phone. And also I'm wanting to get a new Rom. If I install a newer Rom will it do that update or do I need to manually update the El 29?

105 views and no answer. Lol
Well I guess ill just have to figure it out.

assuming you are already rooted: the rom, kernel and modem can all be loaded separate. you could have an EL29 Rom and an EK02 modem. If you're rooted the possibilities are endless. Go to the development forum and all the latest rom.kernels and modems are listed there.
Right now I have EL13 Rom and EL29 kernel and modem. Find which combo works best for you.

[Q] Help learning E4GT Terminology vs HTC EVO 4G

Hey all,
First off thank you for any insight you guys can/will provide. Trying to understand the inter working of my new E4GT, I've had an Evo 4G since launch day. On the EVO the ROMS and Radios could be and usually flashed separately and usually never flashed the radio unless it was borked. In going thru the forums and reading Rooting process and adding CWM to your phine you need to use the same modem name???? I know my ROM is EL29 based? thats what is shown in the Broadband, Kernel and build number. I've seen rooting and mod for like EL13 and EK03 and EGXX..... please help me or point me to a post to understand what EL29 is vs EK03.... is that the ROM version you are using?? and if so why isn't everyone on the lastest version... IN HTC EVO land it 4.67.xxx.
Thanks again for any help

Questions belong in questions but enough of that.
Our phones firmware numbers are date based on the build date, Korea time of course. EG30, EK02 and EL29 where the official gingerbread builds. 2011 July 30th for EG30. 2011 December 29th for EL29. Current leak is FE10 which is 2012 May 10th. Slight misconception among some people that the first letter is the OS version but anyone with an Epic 4G can tell you that is not true.

Ok based on your comment of the 3 Official versions, is the reason ppl don't migrate to the latest official version based on the fact there is slightly different hardware versions that would cuz OS incompatibilities ?

They probably have their reasons but most people are on EL29. I know some people are on custom roms based on say the EL13 leak etc. Some of the things you might be reading for rooting EK02 and back are because there was an exploit for those but not for EL13 to EL29.
The modems are based off the same number scheme and except for EG31 all match the release they came with. Someone might run EL29 rom with an EG30 modem because they feel they get better performance so don't be confused by that mismatch. Edit - I guess that answers your other question btw, you can use any modem with any firmware.
EL13 and up have Carrier IQ removed officially so I would think that a decent reason to upgrade. But the only difference in OS version in the official builds was 2.3.3 to 2.3.6 so I dont think there is much to worry about there. Current leaks are for 4.0.3 and 4.0.4 Ice Cream Sandwich.

Awesome, that really help my understanding of the E4GT environment. So EL29 is the most current stock ota rom. Custom roms are based on various levels of stock roms and leaked roms. Modems/radio levels are like that in EVO land were ppl have various fw levels based on the mileage they get based on device/location.

Yup. I guess I will cover a few things I can think of for you.
EG30 and EK02 were rootable using the zergrush exploit which is patched after 2.3.3. If you were on either one of those you can use sfhub's AutoRooter - http://forum.xda-developers.com/showthread.php?t=1342728. On EL29 we rely on ODIN, the easiest way is to just use a prerooted ODIN One Click - http://forum.xda-developers.com/showthread.php?t=1433101
To return to stock unrooted if you have done no modifications the Auto Rooter will allow for unroot on any version it supports which includes EL29. You can flash a stock unrooted tar for EL29. Or what I usually do is the One click for EK02 and just OTA to EL29 which will leave you on a stock unrooted EL29.
If you are rooted and need CWM the auto rooter is a good place to get it. I think for EL29 it gives Rogue Recovery which was the last one we have and then there is a kernel for EL26 done by chris41g which has stock CWM and is popular for flashing ICS and AOSP ICS roms. Recovery on ICS is dangerous at the moment so people flash back to gingerbread or gingerbread kernels for that.

I was able to figure out how to use the One Click root for the EL29 and then found the utility to add the CWM Rogue Custom recovery... but stopped there. I used Caulkin's Evo GB rom on my EVO and liked it a lot, was thinking I may try his ICS rom, but holding off for now.
Its very different flashing the custom recovery on the E4GT vs EVO.

You might give his EL29 rom a whirl I used to use it. I wouldn't play with the ICS rom until you have played with the stock ICS rom its based off. That way you understand whats causing what and the changes that have been made.

This thread might help you. It has a link for pretty much everything you need to know about the epic touch.

Added bit of info, recoveries are packed in the kernel so it is NOT persistent like the evo was. The recovery will change to whatever was repacked into the kernel you are using or revert to stock recovery if it hasn't been repacked with a custom. AOSP ICS roms have no custom recovery included and should not have one added unless you want to brick your phone, for everything recovery on any ICS, IMO, you should always Odin or mobile Odin el26+cwm kernel/recovery and use that. To create a backup Odin/mOdin the el26+cwm kernel create your backup and flash an appropriate kernel to boot back into your rom when restoring do the same, odin/mOdin el26+cwm restore your nandroid and flash an appropriate kernel. Any time you do anything in recovery on ICS like flashing a theme, modem, add on, etc you will have to flash a kernel afterwards to boot your rom, with the exception of flashing a rom itself as it will include the kernel, so unless you want to use a different kernel than what comes included you won't have to flash a kernel after flashing the rom itself

could I just use the One Click root method for the EL26 that I used to first get root? I used the non data wiping version, could I use that, or would I have to use the data wiping version?
http://forum.xda-developers.com/showthread.php?t=1433101

All u need to use is the kernel, you don't need the entire rom so use just regular Odin v1.85 and put the el26+CWM in the PDA slot and flash then when your phone reboots hold volume+ and power or pull the battery and hold volume+ and power when you turn the phone on, EL26 won't boot an ICS rom so it will just boot loop at the sgs screen. Or you can use Mobile Odin and flash the kernel from your phone, reboot to recovery is same volume+ and power when it reboots or pull battery and volume+ and power. Personally I use mobile Odin since it doesn't trigger the yellow triangle, however I have a copy of the kernel and Odin 1.85 on my PC in case I bootloop when I'm on ICS with no recovery. Triangle away takes care of the yellow triangle and flash counter from an ICS rom for when I use PC based Odin. You can use either the free version of mobile Odin that's here on xda or the paid version on the market, $5 is definitely a fair price for how versitile and convienent the app is. If you use the free version from xda make sure you grab a copy of the sph-d710 flash kernel from the thread where you get mobile Odin cuz it won't automatically download it like the paid version does. You can use the one click method as long as its the one with CWM and not a rogue repack but it's quicker easier and safer to use just the kernel+recovery tar file so you know you always have the right recovery. I just have a copy on my internal and external SD cards and a copy on each of my Computers just in case I have some kind of data corruption I always have a copy in an emergency
