[how-to][condensed]e:signature verification error/aka 3e recovery mod and workarounds

instead of chasing newbies and directing them individually with 3 people giving 3 pieces of advice i though id make a thread explaining 2e/3e what it means, and how to get around the e: signature verification error all in one place.
First, the 2.1 stock rom had 2e recovery. this recovery accepted flashable .zip files as long as they were named "update.zip" . this recovery mode was easy to use to flash roms, kernels, root, modems, cwm recovery, themes ect...
many of the tutorials on this board were written when 2e recovery was still the standard. and many members restore to stock jf6 2.1 and use the same files they have been using the whole time. this creates confusion with newcomers who read old articles for rooting and other mods.
3e recovery is standard in froyo 2.2. it only accept digitally signed update.zip files and forces a full user data wipes after any flash. if you have stock froyo you have 3e recovery! you can not install root or CWM via update.zip with this recovery mode without mods like the old tutorials for 2.1 tell you. but there are solutions to this, and we will cover these below..

what to do?
there are several options, the quickest for you will be based on your end goals
you can either mod 3e or replace it. it can be replaced by flashing a kernel containing cwm in odin or in sgs kernel flasher.
1 if you wish to stay stock but rooted with the ability to flash from recovery the quickest way is: root and mod recovery. either one can be done first depending on which methods you use to mod recovery.
2 for the obsessive compulsive there is this option: flash back to 2.1 with 2e recovery, then you can install new rom, root, cwm, ect... via the update.zip method without issue. Many users consider flashing to stock, a cleaner rom install, but now as most full rom zips do a wipe on install (erasing the stock), this is no longer true.
3 flash cwm enabled kernel via odin, having cwm built into a kernel bypasses 3e. and is your fastest route to custom rom flashing.
4 for those who want a stock 2.2 rom but a modded kernel can root via rageagainstthecage then install sgs kernel flasher or galaxy tuner from the market and flash a kernel containing cwm. this isnt gone over because it is self explanatory
there are many other variations, but these are the ones that made most sense to me
ROOT:
there are 2 methods to root.
1st (old) root method is via update.zip in stock or cwm recovery. this can only work in 2e or after 3e is modified. this was made for 2e recovery. directions are in the thread.
http://forum.xda-developers.com/showthread.php?t=725555&highlight=root
2nd method is to root via rageagainstthecage. this can easily be done with superoneclickroot (automatic) and if that fails there are tutorials on how to do it manually.
superoneclick can be found in the thread below. Make sure 'superuser' app gets installed on phone, if root is successful but no app is present you can download the superuser app from the market.
http://forum.xda-developers.com/showthread.php?t=803682
if the superoneclick fails here are detailed instructions to manually root via rage against the cage:
http://forum.xda-developers.com/showthread.php?t=827544
FIXING 3e:
method 1 (automatic)
you can fix 3e via batch script on a windows pc. look at post 3 below from TRusselo. This method works with and without being rooted first, root can also be achieveved later by either method listed above.
url for download is below: remember to disable you antivirus/anitmalware software
http://dl.dropbox.com/u/19201431/Files/3e_fix-Unzip-ClickInstall.zip
Method 2 (manual)
First root your device via 'superonclick' [directions are above], then copy the fixed file over the old one via ADB, terminal emulator or a root file explorer. I prefer root explorer but there are free apps that can do it. most free apps will require you to mount the system as r/w in terminal emulator first.
the fix file and detailed directions to Manually fix 3e are found in the thread below
http://forum.xda-developers.com/showthread.php?t=909213
at this point you are ready to install cwm recovery via update.zip or rom manager and flash whatever you wish.
FLASHING TO STOCK AND USING 2e: ( obsessive compulsive )
this is not how i do it by the way. but some people like to flash the phone and flash to stock to restore original files and wipe as much data as possible before flashing a rom. in my opinion it is not needed 90% of the time but some roms are weird, and may require original stock files and dont force wipe on install. i may flash to stock if i run into trouble occasionally.
use odin3 one-click downloader 1.0 to flash to 2.1 stock. if you have a 1007 or 1008 (found under the battery) check to see if the phone has working 3 button combo, if not use the 3-button fix with odin3 flashing utility version 1.3+ . If you have rogers and dont want the AT&T to be the splash screen there is a rogers version here. once the 3buttons are fixed avoid flashing with a one-click installer. flashing bootloaders is risky, not that risky but why do it if you dont have to?
Odin3 One-Click Downloader
[optional, removes all data, even wipes internal sdcard] once on the stock rom with debugging enabled you can preform a master clear with the oneclick installer. it does a factory format of the entire sdcard. oneclick is found in this thread
http://forum.xda-developers.com/showthread.php?t=731989
sbl.bin 3-button fixes can be found in these threads:
http://forum.xda-developers.com/showthread.php?t=812434&highlight=3button+fix
http://forum.xda-developers.com/showthread.php?t=818439
if you need one of ^these^ you will also need to use adb or a jig to get into download mode. there is likely an explanation in each thread somewhere in the replies, also the adb commands are outlined in the "safe" jf6 odin thread above. if you avoid odin oneclick you will only need 3-button fix once.
rogers roms are here:
http://forum.xda-developers.com/showthread.php?t=979133
now you can use update.zip files in stock recovery.
REPLACING 3e WITH CWM:
if you intend to flash a custom rom it will be rooted so there is no need to root. instead you can fast forward to replacing 3e recovery by odin flashing a kernel, for this i use speedmod kernel. which kernel you use is irrelevant because it is only temporary. instructions for odin are all over but in the case of flashing a kernel there is no need for any pit file or repartitioning. make sure repartition is not selected, place the kernel in the pda slot, it must be in ".tar" format. put the phone in download mode and press start. this takes no more than 3 seconds and is what i use most often.

did you root before you tried manually? you will need superoneclickroot if not. make sure you properly change the file system to read write. are you using adb? or working from the phone?
if all else fail you can swap kernels right from the phone in sgskernel flasher(after you have root that is), just download a kernel that is built off kb1 and has cwm baked in

I was working from the phone, without adb because I didn't see that in the OP. I am rooted with superoneclick root already...Where can I find the sgskernel? (I really should have payed closer attention in those programming classes). I apologize for the newbie questions...I have had my Cappy awhile just decided to start modding it.
EDIT: I have the sgs kernel flasher... it dawned on me to check the market.

Dani897 thanks a MILLION! I have it figured out! I am now running Phoenix Ultimate! I am so excited...I truly appreciate it. I am going back to see if you have a donate button to donate to you!

I haven't tried this yet but expect it's exactly my issue since my phone is only a few weeks old. The update.zip file gave that exact error and I had to use SuperOneClick to root my phone.
After I try this I might get brave enough to load a new fancy rom but we shall see. I'm in no hurry.

[Q] I need to make "update.zip" working from stock ICS recovey..

Hello
I need to create "update.zip" file that I can apply (flash) using the stock recovery that comes with stock ICS 4.0.3 .. Changing some wallpaper files and notifications....
I found this link :

But I am afaraid that this will not work in ICS , or at least it needs CWM ...
I don't want to use CWM recovery , reason = I have to unlock the bootloader and loose all my data ...
Thanks

You can try to root your device with SuperOneClick and install ROM Manager in order to install CWM.

Now back to topic question :
I need to make "update.zip" working from stock ICS recovey..any tool or how to ?

To my knowledge it needs to be signed by google to do it through stock recovery. We have no current way to sign something like that, which is why we use custom recoveries.

Can't the dev gurus "imitate" the signature from a stock ROM zip ?

Wouldn't it be a whole lot easier to root with SuperOneClick, install Titanium Backup, unlock the bootloader, install ClockworkMod and then restore all your data?
So far Google's signatures haven't been cracked as far as I know, and doing so would probably only cause them to change them. Also, the stock recovery has far less features, such as nandroid capabilities which are very useful if you want to tweak your ROM every now and then.
I know losing the data can be annoying, but if you back it up properly it won't be too bad. Now you're just waiting for the point to bite the bullet and do an oem unlock, because you know that deep down inside you want to. =)

Can I install SuperOneClick from the phone ? Have you got a link ?
Actually I unlocked the bootloader and used CWMR before when I downgraded from ICS to GB (then went back to ICS by the way) , but locked the bootloader again after that ....
Can you please post me a "problem free" root method for stock ICS ROM 4.0.3 ? is it the superoneclick ?

Unable to install CWM Recovery on rooted stock rom, a little help please?

Hello!
I just got a pretty good deal on a stock Froyo Infuse 4G, so I bought it.
A little help please! I would love to have the stock ATT rom with the ability to overclock the processor. This is was I have done so far.. plrease don't be so hard on me since this is my first non-HTC device lol.
So the first thing I did was install a "leaked" Gingerbread ATT stock rom using a program called Odin. Then, I root it using that Superoneclick software... I actually clicked a million times instead trying to get it working because I had GingerBread instead of Froyo ... but somehow managed to do it, it is properly rooted and well tested. So! now with my rooted device, I downloaded Rom Manager from the market, flashed it succesfully (at least that's what the screen said)... and when trying to boot into CWM Recovery I got the following errors:
verifying update package...
E:failed to verify whole-file signature
E:signature verification failed
installation aborted.
I tried to flash it via RomManager several times, also did it via SD-Card renaming it to Update.zip and flashing it with the stock recovery.. same error. I searched for more information, someone in the forum said the reason could be an incompatible Kernel, so I flashed the Community V8 Kernel... and my device didn't boot past the Samsung screen... but somehow if I tried manaully to get into CWM recovery, it worked! (just the recovery). Flashed a custom rom that I didn't like... then suddenly I lost the CWM Recovery and cannot then bricked it and was unable to flash it again..
I managed to restore the phone to ATT factory condition using a guide here on Xda (this time the phone kept the leaked GB rom)... then rooted it again and haven't done anything else. Mu question is:
How can I keep this stock rom with the ability to overclock the processor? (flashing different kernels just makes it freeze on boot at Samsung logo).
Thanks for your help!::

here a good start by me:

1. You need to restore you phone back to stock using gtg's unbrick or heimdall 1 click. (See my post)
2. ATT's GB latest is not rootable thru SOC. You can use odin to flash an insecure kernel (http://forum.xda-developers.com/showthread.php?t=1212485) but you will also need to update superuser binaries and busybox as well. Running the insecure kernel for OC, you will lose the video recorder and video player.
It doesn't sound like you can understand enough yet to do this.
3. If you want a stock att and rooted, go to the dev section:
check out zeus stock 5.2, vagabond or victory. These are GB stock base roms with root already done. There is also dman's deodexed, rooted gb uclb3 already with oc kernel...no video

The first step has been done, restored the phone using Heimdall one click after bricking it, the phone was restored with a UCKJ4 2.36 GingerBread stock ATT rom (Kernel 2.6.35.7-I997uckj4-cl694350) and I am also rooted using SuperOneClick.
I don't fully understand step two, will try it once I get some more knowledge.
Question about the third step... does HDMI work in any of those custom stock roms? I use HDMI a lot.

{ROM}{STOCK}{ICS} Rogers Official UXLF3 - UNTOUCHED - CWM5 flashable

THIS IS NOT A CUSTOM ROM. THIS IS STOCK OFFICIAL ROGERS ICS UXLF3 FIRMWARE. PLEASE DO NOT ASK FOR MODS, I HAVE PROVIDED THIS UPON REQUEST.​
INTRODUCTION
Click to expand...
Click to collapse
This is the Stock Official ROGERS/Samsung Released Firmware for the SGH-I727R (Skyrocket) based on Android Platform 4.0.4 aka ICS. It is targeted for:
* Anyone who wants to be on the stock release, doesn't want to use ODIN.
* Wants to build a custom rom, and needs an official base. (see post #2)...
* Or, you just want a baseline.
PACKAGING

Well it is Stock, untouched, except for the deodexing and zipaligned. Your kernel and radios will be updated as in the official update. The only thing I have left out is the recovery, and I can provide a flashable one later, if you really really want to be stock for any future OTA update. See the optional flash if you need busybox and su.
- DeOdexed as per my stringent process, no using Kitchen or any other nonsense. Every apk get's what it needs in the classpath.
- zipaligned.
- all ownsership and permissions exactly as in stock install.
- Untouched UXLF5 boot image (i.e kernel + ramdisk).
- Your radio/modem will be updated to UXLF3.
- [OPTIONAL] If you want to flash busybox/su see the ADD-ONS. This will effectively root your install.
- [OPTIONAL] If you want the modified boot.img that enables init.d scripts, bootanimation, insecure boot, then flash the boot.img listed in the add-ons
INSTALLATION
Click to expand...
Click to collapse
Pretty straight forward. The only requirement is you need CWM 5 and above (I have tested with the touch recovery). NOTE: THIS WILL WIPE DATA.
1) Backup, Nandroid preferred.
2) Download and Copy the ROM to your device. (Please make sure you check the MD5SUM, the dowload link has the correct one).
3) Copy any additional add-ons you want to your devices, internal or external sdcard.
4a) Boot into CWM recovery (remember that is the requirement).
4b) In your recovery format /system (in touch recovery it is under: "mounts and storage)
4c) wipe data and cache partition
5) Flash the ROM.
6) [OPTIONAL] If you want busybox and su (binaries only). This will ROOT your phone. Flash it now.
7) [OPTIONAL] If you WANT the modified boot.img (modified ramdisk + stock kernel) flash that.
8) [OPTIONAL] If you want to flash a *different* radio, flash it now.
9) reboot

Yup just deleting the binaries is enough to "unroot". I may update the op with the revert script (busybox and su) and the respective stock recovery, when i get chance..

Very nice work, Maybe I should give it a try lol.

i have installed this on my SGH-i727 ATT handset.
By far this rom gives the best battery and performance...

But this rom is having shutdown/reboot freeze issue.
Embryo 4.1 is discharging battery than any other roms, otherwise it is also ok.

Hi mohan,
Is there any way you could do the same for Rogers GB? It would be a great help for me. As ICS is crap I get RR and freezes. It doesn't get the right time zones and etc.

Incredible rom! Just had my skyrocket for 2 weeks, flashed 5-6 jb roms, vincoms the best imo, seanscreamz close behind.
I thought I'd come back to stock for a couple reasons. One, to get a baseline and see how good stock Rogers ics is battery wise, two, I can't seem to get nfc figured out and want to see if stock will do it. A co-worker has a stock ics sgs3, we can transfer apps, web addresses etc., but where he transferred a feature film to a different co-worker with a stock Rogers ics sgs3, via nfc in about 30 seconds, it fails with my skyrocket. I notice that their phones have sbeam in addition to nfc and android beam, maybe that's the difference. But I was wondering if there's issues transferring between ics and jb?
Thanks!

Sorry to double post but I thought this would be as good a place as any to post this. Went in to Rogers today to get my lte SIM card, to my surprise they didn't even charge me! I can't believe these speeds the screen shot shows the speed is double my Wi-Fi speeds at home! And look at the comparison to the 3g or H+ too, that's just sad. I'm expecting to pay for it battery wise but I can live with that for these speeds!

[Q] CWM Touch Issue

I first want to start off that I am brand new to all of this. I have been reading up about this for a while and finally decided to root my Galaxy S3 the other night. I followed the instructions by Phone Rebel in his Youtube video. I used these files: Download and Install Samsung Official USB Drivers - Link
Download and extract ODIN v3.07 - Link
Download the Zip Below
For Both Root and Unlocked Bootloader ***RECOMMENDED*** – Download SuperSU + Unlocked Bootloader to your SD Card - Link
Download the VRALEC Bootchain - Link
Download one of the below
For ClockworkMod Touch Recovery 6.0.1.2 (Download this to your computer) - Link
For TWRP Recovery 2.3.1.0 (Download this to your computer) - Link
Download the VRBLK3 Bootchain - Link
After completing the root, it automatically installed SuperSU. (not quite sure what it does, again, i'm very new to all of this) After reading up on what to do after you root, I read that it is a good idea to download ROM Manager as well as Mobile ODIN. I installed both, difference being I bought Mobile ODIN Pro.
Using ROM Manager, I tried flashing CWM Touch, I was successful in doing so. However, when I boot into recovery, I get a message stating that ROM will flash back to stock after boot. Do you want to fix? Yes= this can not be undone. No. Or Go Back. I was scared to press yes because I didn't know what it would do. I have not installed any custom ROM because I'm not 100% sure on how to do it so I am not going to take the plung until I know.
Any suggestions or answrs on how to fix this issue would be appreciated. I do want to flash a custom ROM like Cyanogenmod. I've just read that it's a really good custom ROM. Any ROM suggestions will be greatly appreciated as well.
Also, I've read that you have to back up IEML or IMEL? ( I probably butchered that all up, again i'm sorry) I have Titanium Backup, can i do it with that? And if you install a custom ROM do you have to do a wipe of your phone? If so, how do i do that? And if Verizon releases another OTA update, can I accept it or will it brick my device?
Thank you in advance for all your help.

It will ask disable stock recovery flash. You have to say yes else it will flash stock recovery and you will loose the cwm touch recovery which you flashed.
Thanks doesn't hurt....

As for the imei backup, you can not use Titanium Backup. There is a thread which talks about the imei backup and restore process. Try searching for it.
