Im trying to flash calks e4gt 2 v1.1 but every zip i open gives me a signature verifcation error. I am currently on stock rooted fc05.
The re-enabled signature verification in FC05 so you can no longer use stock recovery to install ROMs.
People have been advising to flash back to a GB ROM, install GB-based CWM, then install the ROM from there. There is a big note at the top of steady's CWM thread to not use ICS-based Rogue CWM to flash ROMs, which explains why people are suggesting going back to GB-based CWM to flash ROMs. I believe technically it is only important you install GB-based CWM - ie the GB kernel, not the ROM, but folks probably suggest the ROM also because they don't like it when the GB kernel won't boot an ICS ROM.
Not saying you will definitely have issues with an ICS-based CWM flashing ROMs, but this is the method folks are suggesting to flash ROMs.
So what is the best way to go back to gb can i use stock recovery or do i need to do it on a pc. Thank you for the help btw.
The quickest way is to use Mobile ODIN or Auto Root to install a GB-based kernel+CWM like EL29+CWM-Rogue. This will put you in a situation where you phone won't boot into ICS, but you can boot into recovery.
If you are not comfortable with the not-booting situation, flash the pre-rooted EL29 ODIN OneClick, either from a PC or through Mobile ODIN:

Then use Auto Root (or Mobile ODIN) to install EL29+CWM-Rogue:

Thanks for the suggestions, everything worked.

Hi all, I'm new here (well, not to XDA) as I just purchased this phone 2 days ago. I love it so far. It's such and upgrade from my LG Optimus that I almost considered not rooting or flashing ROM's. Of course, I caved in last night.
Anyway, I have a couple questions regarding Odin and the process around flashing different kernels/modems, etc. Any help would be great. I successfully flashed Blue Kuban without issues as I'm familiar with CWM and all that great stuff.
1. Is there a good tutorial that I can use to do more research on Odin? I see there's a mobile version and a PC version, so I'm not sure which to use.
2. I see in some ROM's, the install instructions state to first flash a specific kernel with Odin. Is this to prevent bricks from flashing from ICS to ICS ROM's?
3. Hypothetically, if I wanted to switch from Blue Kuban to CM9 (or any other ICS ROM), couldn't I just restore my stock GB back up and then flash CM9 (or any other ICS ROM)? If not, what is the most user friendly method you use?
Thanks all, really glad I chose this phone, it looks like there's awesome development for it! Any help is greatly appreciated!

1. OK for Odin, you can try searching for a tutorial on qbkings YouTube channel. Basically all you need to know is that the PDA slot is for kernels and such where as phone slot is for modems. Only have auto reboot checked in top right settings. Mobile Odin works the same way. You can flash kernels from there and can save you time and when you're away from a computer. It currently has problems flashing modems however. There is a paid and lite version which you can find here in xda if you search a bit.
2. Yes this is to prevent bricking which has been happening when wiping data/factory rest in custom recoveries repackaged in ICS kernels. This is why its recommended to go back to el26 because this is the last true source (we don't have ICS source yet) we had.
Whenever changing roms, you must Odin/mobile Odin the el26 cwm kernel and do any rom flashing, restoring, backing up from there. So if you want to switch to CM9 from the ICS version of Blue Kuban I'm assuming, Odin el26 cwm kernel and flash cm9+gapps there.
Anymore questions let me know

Awesome, great info and I'll definitely pick up the mobile version. So it looks like I only need to flash the kernel, not actually flast a GB Rom?
The only other thing I'm wondering is if you recommend using the Rogue CWM Recovery. I have it installed right now. Are all ROMS compatible with this recovery?
Thanks again for your quick and helpful answer!
I personally use the rouge 1.4.1 kernel to do all my flashing. Rouge recovery is built from tweaking the cwm recovery. In essence, they are the same thing. Rouge has less "no's" and the menus are better organized, so I use it.

Yea all you need is the kernel. If you're on an ICS rom when you flash the el26 cwm kernel, it won't boot your phone but you can go into recovery still.
I really wouldn't recommend any custom recovery at this time for ICS. I mean it takes maybe an extra minute odining the el26 cwm kernel or so instead of directly booting into rogue recovery. From there you can flash mods, tweaks, etc and then just reflash a compatible ICS kernel. What do you really need rogue for? Not worth the risk IMO.

Interesting. I'll have to read up more regarding Odin. So I could literally open Odin and plug my phone in and then flash the el26 kernel and flash whatever ROM I want from Odin as well? Sorry, a little confused there. Just not sure how I'd flash a ROM without a custom recovery.
Thanks again, I'll also check out some tutorials. I'm guessing it will feel like 2nd nature in a week, just learning the new process.
The recovery is built into the kernel for this device. I use odin, flash the el29 rouge kernel v1.4.1, when the phone resets after the flash, boot into recover using volume up and power, wipe, flash, whatever you want, make sure you reinstall ics rom or kernel if you are on ics and reboot.
Ah, so if I flash the EL26 Kernel, will that overwrite my Rogue Recovery?

Well download whatever rom+mods/etc and put the files on your phone. Then just odin/mobile Odin the el26 cwm kernel and flash whatever you want from there, ICS or GB without no chance of a brick.
On our phone and I think most Samsung's for that matter, the recovery isnt separate from any other partition like with HTC. It must be packed into the kernel. So whenever you flash a rom, whatever recovery is packed in with that kernel included with the rom is what you're getting. Most devs are packing in stock Android recovery to cut down on bricks and instead recommend always flashing from el26 cwm kernel.
So yea that's what makes mobile Odin so great. Have el26 on your storage and you can switch roms very fast, easy, and safe.
Anymore questions just ask.
Edit: are you on GB or ICS Blue Kuban and what rogue also?

Thanks, really good info. I'm on Blue Kuban ICS right now with Rogue CWM 5.0.2.7. Looks like Odin will be a very easy way once I get comfortable with it.
So basically, I'll put the kernel zip in the PDA slot in Odin and let it do its thing, then my phone will auto reboot into the kernel's recovery where I can flash the ROM? Or do I flash the kernel in Odin, and also flash the ROM in Odin as well?

Odin is just used to flash the safe el26 cwm kernel onto your phone. It will auto reboot and just hang at the Galaxy S II screen since the GB kernel can't boot an ICS rom so just power+volume up into it. Hold it for maybe up to 15 seconds but it'll come around. You then flash the rom in recovery from there. So put you rom files, etc on your phone before you Odin the kernel.

oh ok sweet. That sounds pretty easy, actually! LOL! One last question hopefully, do I need to extract the kernel zip or do I just place the zip in the PDA slot?
Thanks again for your help today. It really cleared a bunch of questions I had.

Kernels flashed through PDA slot in Odin will be in either .tar or tar.md5 format, .zips are for cwm recovery only. You can find the el26 cwm kernel in the kernel repository sticky in dev section, its the first kernel listed. No problem, glad to help.

Hi all,
I just got a replacement E4GT from Sprint, I had planned on staying stock but after the hardware issues of my first iteration of this device and the somewhat lackluster update, I decided to take control and root/flash.
I used to do this on the EVO but it's been a while.
so I followed QBKing77's videos to the best of my ability. I have Rogue Recovery installed (pretty sure it's the latest, I downloaded from the official thread and ran the exe to install less than an hour ago). It's doing NAND backup and recovery just fine, so I assume Rogue is working but I can't install AOKP or MIUI.
From the video, it seems like I use the zipped file on the phone's memory, do I need to unzip first?
Can I flash directly from a EL29 Rogue to an AOSP ICS ROM?
Use Chris 41g's EL26 CWM kernel for initial AOSP flashes. Though if your stock now are you not on FF18 ICS yet?
El26 rogue for flashing.

No, No rogue for AOSP. Custom CWM bricks. Rogue was the popular one at the time, pretty sure there was another one that was not working as well.
EL26 with bone stock CWM.
RainMotorsports: I am on EL29, I've had the replacement for 3 days and it has not updated. I could follow the manual update but I hear most people like to flash from GB ROMs because they're stable?
also, I'm sorry, I don't understand flashing kernels. Don't we have to flash an ICS rom before we flash a kernel? And I thought the AOSP kernel was stock with Milestone 6?
rovar: So should I Odin back to EL26, re-root and install a recovery? Does that have a better recovery?
I'm wondering if I should just unzip the files and try again...
You can flash the EL26 cwm kernel on to the phone as is. If its rooted sfhubs auto root tool can do it for you http://forum.xda-developers.com/showthread.php?t=1342728. If its not rooted you can flash the tar for it in odin. http://chris41g.devphone.org/index.php?dir=EpicTouch/Stock+Repack/EL26/
As far as FF18 goes the leak was the OTA you can NoData one click for an OTA like experience where things are not perfect or wipe the phone with full data. http://forum.xda-developers.com/showthread.php?t=1721229
I can approach the rom/kernel question from 100 angles. But you need a kernel with the proper recovery to flash the rom, when you flash the rom the kernel is overwritten with the kernel in that rom. To get another kernel you once again have to flash a kernel. I do not keep up with AOKP. CM9 since alpha 6 has a safe cwm5 based recovery and it + the nightlies use a repacked stock kernel. Chris 41g is testing some from source kernels for both, the AOKP one requires his version of milestone 6 and thats my extent of knowledge on the state of AOKP kernels.
AOSP roms flashed with EK02 through EL29 rogue brick. Chris41gs EL26 CWM has been the tried and true kernel. You could flash the kernel of a TW or AOSP rom, the phone will not boot until a matching rom is installed but we did the reverse (EL26 kernel while the rom was still ICS) all the time.
Thank you. I found a video that showed how to get stock EL26 CWM Kernel installed via Mobile Odin. I am trying to make a second backup because I'm not sure the Rogue Nandroid is compatible but it's having trouble making a backup from here. It seems that it's only recognizing 200mb of free space and I know there's a lot more.
It seems that the EL29 Rogue backup I made won't restore to the EL26 kernel/EL29Rom I'm now running. I'm going to delete the old backup and try to make a new one.
Anyway, sounds like I'm pretty close!
And I'm now running AOKP. Thanks so much! You guys were fast and helped a ton!

Nice. I bet the addiction is already setting in. I just went from CM9 Nightly 7-22 to an early 4.1.1 AOSP build back to TCP's 7-28 CM9 which i had no clue what to expect from but I am on it now. Must must must flash them all!
Edit - I just flashed FF18 forgot I wanted to PRL update and fix my boot image while I was at it.
Hey everyone, I have a few questions:
So I'm on stock GB27 (unrooted) but I am in the process of rooting it right now as we speak, so that shouldn't take long. What I want to do is get onto a safe recovery though to flash this ROM (Vanilla RootBox for E4GT), preferably EL26 recovery (which would be CWM 5.0.2.7 if I remember correctly) because I don't really know how safe AGAT's recovery is to use. The reason I bring up AGAT is because I use a lot of qbking's videos to get me through the rooting/recovery process and the one linked above is for AGAT's.
So I was wondering if anyone could help me get into a safe recovery from GB27 rooted so that I could flash the Vanilla Rootbox rom.
Thanks in advance.

EL26 is completely safe. Just download the Rom zip to your phone. Flash the el26 tar using pc or mobile Odin, reboot into recovery, wipe data, cache, dalvik, flash rom, reboot, enjoy.
Edit: from the rom OP, says you have to flash gapps too. Basically, once in cwm just follow op from there. Good luck!

AGAT Recovery with stock kernel is not good to use.
The EL26 / DirectBoot EL29 Kernel + Recovery is the safest and recommended for flashing all because it's base is gingerbread
and it doesn't have the EMMC corrupt super brick bug.
I'm not entirely sure about Agat's SOURCE built kernel though, I think the source built kernel + recovery is safe for only flashing
mods and extra's. But I've never used it for wiping and flashing roms for GB27.
Tim did a video post on using AGAT's recovery source built kernel and he does say it is safe for only flashing
TW based Roms for the specific firmware it's for.
An example would be
Agat's GB27 Source Kernel recovery for only GB27 roms
or
Agat's GA10 source kernel recovery for GA10
etc
But for sure, it's best to use the safe recoveries or recoveries recommended by the Rom threads.
Hopefully this info helps a bit.

Your information is not entirely accurate. Agat's Kernel IS safe, and you can flash GB27 on GC01 and GB28 Roms as well as GB27. When source first dropped, there were quite a few bugs, however, those have been worked out, and Agat's is VERY good and can be used for a daily driver. It can flash Roms, mods, tweaks, can overclock/undervolt, backup/restore, mount usb, etc, etc. EL26/EL29 are still the default for most OPs, but if you flash a JB Rom, it is certainly safe to flash another Rom using Agat's...
Typically, when handing out advice to other members, you should verify that what you're saying is true. As was stated, you're not entirely wrong, the safe gb kernels are still recommended, however Agats is perfectly fine as well. Stay up to date on development before you spook people away from a perfectly fine kernel
I said agats recovery on STOCK KERNEL is not safe.
And I've been told that agat recovery is only used for flashing mods.
I've also stated I'm not to sure about flashing on agats source
when your switching between ROMs with different build version from GA10 to GB27.

Agats recovery on stock kernel is fine also, these issues were resolved a while ago. So I reiterate, please be up to date on development before making statements which could have a negative effect on a developers work. The majority of failures flashing between versions are user error (not checking md5, not wiping properly, not flashing properly, etc)
If they fail to follow directions, thats not the kernels fault, its theirs.
Slithering from the nether regions of a twisted mind and tarnished soul
Hey guys sorry if this is a noobish question but I am currently on GOODNESS JB ROM. Today I noticed that for some reason i don't have a custom recovery installed. So I need to flash a CWM but am not sure which one. The last time I made a nandroid I had flashed EL26+CWM using mobile Odin. Does that mean I need to find that same version of CWM but WITHOUT the EL26 kernel??? I don't want to mess up my phone as I do NOT have access to a computer. Thanks in advance.
Only JB kernels with recovery are GB27 that I've found. Goodness is FK23 I think? Garwyns 0.4.0 has cwm but all the others have Agats Recovery....I THINK...so be careful

Instead of flashing custom recovery, can I just go straight to flashing another ROM to get a working custom recovery? I can just mobile Odin EL26 and flash a different ROM like project X 4.2.2 and end up with a permanent custom recovery right?
