[Q] compatible rom with hotspot for EL26 and otherwise stable

just got a replacement phone from sprint. it came with EL29, although I just rooted with the one click method for EL26; so now my build is on EL26.
was reading that Calkulin's rom forum.xda-developers.com/showthread.php?t=1332837
had everything I wanted; except it was built on EL29... anyone know whether or not this will work for me or should i search for another rom?

For what reason do you want EL26? EL29 is the newest if you have not found out. Just curious as to why EL26...
Great roms are
Blend 2.6.2 has themes
Dark blend 1.2
Caulks newest
Phantomhackers
hell ALL EL29 has what you need
Just choose the features and look you want.

to be real honest, i was confused when i first rooted. that is, i downloaded EL26 vs EL29 when rooting and now am nervous about going back to install the root again in order to get the newer version. however i think i will do that now

You dont need to reroot nothing. If you are currently rooted, your good to go. Just flash the EL29 modem and then flash your rom of choice. Its easy as cake. Just as long as your rooted with recovery.

[Q] why 26

Am I missing something,why do some of the ics require you to go to 26 and some are ok with 29?can someone please explain to me.thank you.

User preferance, EL26 contains CWM recovery which is reported safer than any other version for flashing ICS based ROMs, which a lot of people were getting bricked from... I personally have flashed every ROM made here/ avaiable to the public and only went to EL26 for AOSP/AOKP/CM/MIUI ROMs as this is a required step in their threads! No to revert back Which I do not recommend-I never reverted back I just simply flashed back, however if you're willing to risk everything then have at it -Though it is not and I do not recommend it
Also some kernels do not have a custom recovery so to odin back to EL26 or whatever is the best and safest option.

That pretty much sums it up, I have flashed my fingers to the bone.im looking for themes for Roms now I've gone through them all also.some roms(only ics) give me a emmc error while running.So in a nutshell it's all about preference.thanks.

Safe Flashing

Hi all, I've been reading a lot of threads around here about safely flashing our phone. I'd like to verify somethings before I go around flashing things.
It is my understanding that its ok to go from any rom to any rom using sfhubs odin oneclick methods. Is this correct?
It is also my understanding that I can flash any rom (unless otherwise stated) from CWM recovery safely if I am back to EL26+CWM using ODIN.
I have some confusion about this. Currently I am on a stock EL29 unrooted build, if I want to flash an ICS rom would I flash the EL26+CWM tar via ODIN and then use CWM to wipe and flash ICS? Is it also required that I flash an applicable kernel along with the rom?
Also I have never used odin before. Do I need to install this program from somewhere first before I can flash things?
Do I need to root my existing EL29 setup before I can flash the EL26+CWM tar?
Sorry for the huge number of noob questions, I just don't want to take chances with my phone. I'm an HTC guy and things seem to be done very very differently there. I'm very interested in trying the upcoming date to the Blend ICS "The Goodness" rom.

1. Yes as long ad you get into download mode
2. Yes
3. Yes but usually roms come with a kernel that works already, check OP for each
4. Yes get either mobile Odin from the market or get it on ur PC (best to have both)
5. Yes you have to be rooted to flash anything

The best advice I can give you is to look up qbking77 on youtube. He has step by step how to videos on rooting and flashing your E4GT.
Start here. http://www.youtube.com/watch?v=v7pWjmKCsoc&feature=plcp
He has a link in the description on how to add CWM

Ill tell ya right now I would not recommend flashing an ICS rom it is soo buggy I hate it! I just installed the tablet one I forget what it is called but nothing but force closes even when ya aint doing anything it will just force close on ya. Stick with gingerbread untill there is a final release for ics trust me. Way to buggy right now!

I must agree with RB!
I would not mess with ICS if you are new to this phone (and even some that are not ). If you really like your phone, I would recommend trying out the many Gingerbread roms for a while. It is a much safer and far more stabile learning platform than ICS.

As far as flashing ICS I would check out one of the official leaked builds before trying out a custom ROM. I've noticed that some people seem to have different problems even though we all have the same phone. The changes from GB to ICS were enough to drive me nuts sometimes, but I've been using the leaked builds with minimal problems for the last few weeks. The newest one is FE10 and is here: http://forum.xda-developers.com/showthread.php?t=1648045

I have to say I take back what I said I was getting all those force closes but then I did another factory data reset and now it is running smooth and I am LOVING ICS!!! You should check out the Hydra Rom by team Venum it is soo sick! It makes your phone like a tablet!!!

True you can use either Odin or Mobile Odin (and it is best to have both). But I find Mobile Odin much more convenient. I always keep an the EL26+CWM tar and an ICS Tar (Kernals) on my phone at all times. It is much safer to do anything on the EL26 kernal such as wiping, flashing, nanding, and etc. Even if you are on an ICS rom you can Mobile Odin to the EL26 kernal flash whatever you want, and lastly flash back to an ICS kernal and reboot. That is about as safe as you can be. Like the other posters said though try out some GB roms first there are many great developers, and these roms generally have far less risk associated with them. I am currently running Epic Venum Rom and it is great. Happy flashing!

Yea ya see sometimes when people ask for opinions on here I say try it yourself because its different for everyone. My battery life compared to yours and my user experience compared to yours. I am on Codename and have 0 issues and honestly dont even need an upgrade. I could rock this ICS till my next phone.
Hey OP do yourself a favor read yo ass off up in here and please please please follow directions to the "t" and just try out a few roms

LMAO RB. You're really gonna confuse the guy now.

Thanks for all the informative responses all. I think I mostly have this down now.
I rooted my stock build with sfhub's odin OC, then used sfhub's autorooting utility to flash EL26+CWM. Got into CWM and wiped everything a few times and then flashed Blu Kuban ICS.
Now that I tried this, if I want to try a different rom should I just Odin OC back to my rooted EL29 build and repeat the process or would it suffice to just use the autorooting utility, flash EL26+CWM and then flash my new rom?
Can anyone recommend me an ICS rom that is fairly similar to a stock ICS experience? It doesn't have to be CM9 or AOKP. I'm just tired of Samsung's cartoony icons and themes. "The goodness" seemed interesting.
Also what is the best Gingerbread rom around here in case I decide to stick to that? Any that are themed like ICS?
Also if I wanted to, I could go from my blu kuban ICS rom straight to FE10 using the Odin OC safely right?

Thanks for the help all. I settled on tFE10_v0.1.0, a tweaked version of the FE10 leak. It's also skinned to look like stock ICS and I'm using it with the ICS launcher instead of TW.
Smooth, stable and good battery life so far. I'm quite happy with it.

Odin OC back to EL29. It is HIGHLY recommended that you not flash GB kernels on ICS roms, so flashing EL26 from ICS is not ideal. Insofar as rom i was on goodness until just recently, which is great, but recently switched to AOKP build 35, which is AMAZING

I would just flash el26+cwm from mobile odin/odin and boot into recovery. Once there just wipe and flash like you did for Blu Kuban. You don't have to go back to GB ROM, just need el26+cwm. As stated above it is unsafe to flash to el26+cwm using ICS recovery, but is safe to Odin/Mobile Odin to it. I always have stockel26cwm.tar, an AOSP kernel, a stock ICS kernel, and whatever ROMs I'm currently using. I also always have Mobile Odin and Root Explorer installed.

Wow you just saved me a whole lot of time. This whole time I was under the impression you had to odin back to Gingerbread rooted, reinstall CWM before flashing another ICS rom. I never knew you just needed the el26 kernal! Thank you! Quick question though what slot do you put the kernal in the PDA?

Here's a direct link to the stock el26+cwm: http://db.tt/0QJkleJR
I believe you use PDA slot. I use Mobile Odin as I'm always at work and never near a computer. I do believe there is a free lite version on these forums somewhere or its $4.99 on Play Store, but it is a huge time saver as I flash a new ROM several times a week at least(currently addicted to HyDrA).
Sent on HyDrA using Tapatalk 2

thanks kill, i was odin OC back to EL29 before each flash, i will adopt your method going forward, i should have realized this a long time ago...

No problem. Just trying to save you some time/effort. One more thing though since I don't think it was ever mentioned. You should always verify the md5 checksum before flashing anything. There are free apps on the Play store to check with and most developers post a checksum by there downloads.

[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.
http://forum.xda-developers.com/showthread.php?t=1391732

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

4.0.4 Update with Root and Custom ROM?

Alright, so my phone isn't on 4.0.4 yet, and I was wondering if it would be safe to update it even though I have a custom ROM installed. The ROM I'm using is Blazer ROM EL29 v4.0, if it makes any difference.

What are you asking? Do you just want to jump to ICS?
You can use sfhub's one-clicks to get to stock rooted FF18 (the latest OTA version). With sfhub's one-clicks you can try the 'no data' version (to preserve your user data) but you may experience some wonkyness. If so use his 'reset data' to just completely start fresh. Then use sfhub's Autoroot package to add a custom recovery - CWM+Agat_safe kernel.
You can then use CWM to install what ever ROM you choose - as long as you read AND FOLLOW the developers recommendation for installing their ROM.
Nearly all of the ROMs are so polished and reliable you really can't go wrong with any of them Try them out and see what works best for you. The devs here are all pretty awesome.

I was on blazer 4.1 before jumping to ics too. I used format all zip and flashed blazer ics in recovery. I then flashed agats latest kernel right after. I believe blazer ics was using an older version of agats kernel.
Don't forget to flash the ff18 modem if you want it.

I was wondering if I could just apply the update, without using Calkulin's Format All. Like, if I were to apply the update without removing the ROM I have installed at the moment for 2.3.6. I'm not worried about a ROM for 4.0.4, just whether or not I could apply the update to my phone as is.

If you receive the ota update and try to install it, it will fail. Blazer ROM has changes to the system files that will cause it to fail. If you are on a custom ROM, there's no point in dealing with ota updates. The dev of the ROM will update it anyway.
If you want ics and rooted, then follow what leader said above. I was just saying since you were already on blazer, the blazer ics is a great ics rom.

Well sounds like your trying to 'save some time' by not going the full wipe route or the other one I suggested - use sfhub's FF18 One-click 'preserve data' (which by the way is like an OTA update they - Sprint/Sammy release interneally) and then seeing if your data keeps/is intact and there are no issues. Then adding CWM via his Autoroot.
IF you use the above method you have a very good chance that your data will be intact and you will then be able to 'move it forward' to other ICS ROMs.
From there you can flash the 'Modified_Calkulin_Format_All' which keeps data then flash the latest Blazer and see how that settles in and if you have any issues.
I've used this method on no less than three devices and all worked and worked well.
OR
You can try the 'fast way' [with which you may still end up having to do a complete 'reset data' Odin flash anyways if it tanks]
Use CWM to install the latest modem of your choice (FH13 has been great for me and many others).
ThenTry using Calkulins Modified Format (keeps you 'data') And after that flash the latest ICS Blazer.
Good luck.
