[Q] Getting back to 2e recovery on xxJPC ? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
I've been reading and searching here and on other forums for a while now and there seems to be no answer.
Got my new Orange branded SGS I9000, tried rooting using z4, which took ages then did the vibrate hang thing and rebooted the phone, unrooted. I assumed the z4 exploit was patched out in froyo. A few minutes on XDA and I succeeded rooting with SuperOneClick. Backed up efs, Installed ROM manager, tried and failed to install CWM.
It seems that in order to be able to install CWM (or any kernel/rom updates really), I need to go back to 2e recovery.
Multiple threads discuss this exact issue and many users report success in downgrading to 2e recovery using Chainfire's CF-Root. The thing is, that thread (http://forum.xda-developers.com/showthread.php?t=788108) does not have a xxJPC version.
It's very frustrating. In order to be able to safely play around with interesting roms and perhaps solve my nerve shattering lag issue, I need to do a nandroid backup, which requires CWM or a similar recovery, which are all signed using an old signature thus requires stock 2e recovery, which requires a JPC CF-Root, which.. does not exist
Is there anything I can do to go back to 2e?
Ever since I rooted the phone feels much more laggy. There's a frequent keyboard lag and booting takes about 7 minutes till the homescreens fully appear
According to everything I read here, just about any of the newer roms will most likely fix the lag. Even voodoo on it's own should do wonders, right? I just need help getting to a proper 2e recovery to be able to get there. Curse samsung for adding yet another hurdle on the way to freedom.
Suggestions or insight of any kind would be greatly appreciated.

There are other kernels that include 2e recovery like speedmod.

Will 3e let me install speedmod just like that? Is it signed differently than CF-Root?
Thanks for the unexpectedly quick response!

Installing Update using Clockwork and OTA JH7 taking an hour?

The bar has not filled up...What to do? Quit and try again?
USed Clockwork mod to find and install OTA'JH7.zip
Searched for it
found it
Installing hangup and nothing in the bar indicating anything is being done
Did you have any lagfixes installed prior to trying to update?

My history is as follows:
Stock to Root
Back to stock
Installed JH7 via mini Kies
BAck to stock
(Learned how to use adb to get into download mode)
Loaded Froyo "Officical beta"
Wanted to try the Clockwork mod so I went back to stock using ODIN
Installed the Zip files in proceeded to install Clockwork then searched for and found the OTA file
There are two files out there. JH7_OTA.zip and JTA_OTA_STOCK.zip
The latter did not work and hung up on install..I loaded the former and it installed.
Now a few questions regarding Clockwork
I dropped the Cognition 2.2 5 in my root directory..Can I load that in the same way? Then go back to the JH7 when the Official 2.2 froyo comes out? Whether rooted or not?
If I want to root the phone I will have two update.zips in the root directory (Clockwork and the root upadate.zip)...Must I remove Clockwork? IS it loaded or does it execute from the zip every time? Can I rename the Root update.zip to something else now that I can "find" it with Clickwork?
I like the clockworkmod and will definitely pay for it if it allows me to change ROMS I place on the SD on the fly rooted or unrooted (would never need to go back to JH6 and deal with adb if so)
Final question,,,Shoudl I use clockwork to "reset the battery?"
I do not intend to do any lagfixing beyond whatever is in Cognition since that seems to be more of a problem than it may be worth
Thanks...Its been two weeks since i became an Andriod fan and i have learned alot.....and still am
Read the Cog wiki, there have been so many versions I can't remember all of them and the install instructions, some you needed to flash through Clockwork. Cog 2.2 5 Is Froyo whicj means you can not use Clockwork to flash anything with Froyo running because Froyo is not an official release and is BETA it is not signed, Koush hasn't found a way to sign it in order for Clockwork to work with it yet. Clockwork is worth having the paid version yes. You must be rooted to use ROM Manager so unrooting you loose access.
If you are using JH7 that you flashed check if you have SuperUser in your apps drawer, if so you are rooted. Get used to Odin if you are going to mod your phone you will use it more than you think and it becomes less scarey the more you use it.
You've already modded your phone so OTA updates will not work for you, mini kies will so go ahead and flash away, you will eventually have to flash with Odin to update with mini kies so go have fun. Also, those guys on the dev section will have the official up as soon as it comes out. We had JH7 within a few hours, none of us could do the OTA and AT&T bricked a lot of phones so I will only use stuff from Samsung anyways.

Yeah I have two phones and one is the guinea pig. I have my main phone on the pre release of Froyo. I am practicing getting the second phone eventually from Cognition2.2 5 to Samsung's official release. I have used ODIN probably 10 times to get back to JH6 where I have to use the adb SDK to get into recovery/Download modes.
The OTA updates did not work for either phone which is why I began modding and learning, Mini Kies was the only way to get JH7 until now with Clockwork.

Root and stay on stock 2.2.1?

Hello,
I read most of the guide but couldn't find certain answers there nor by search, but apologies if I missed them elsewhere.
1) I'm happy with my SGS, I always used stock ROMs and am now on 2.2.1. I'd like to get root access and leave the rest as it is, however.
Is there any way to get root access with the stock 2.2.1 ROM without switching to a completely different ROM (as said, I like the stock ROM and don't feel like changing the layout, features and all that come with a new ROM)?
I saw that superoneclick thread but apparently it didn't work for everyone and questions are usually not answered there if people run into trouble so I didn't dare that yet.
2) Still a bit confused about the 2 modes. Do I need recovery mode to work? Or will download mode do to flash (if I have to) and rescue/fix my phone if something goes wrong?
My 3 combo button never worked so I bought a JIG dongle on ebay which gets my phone into download mode at least, but I still have no recovery mode yet that's why I'm asking.
Thanks!
There's an app called Quick Boot which will allow you to get into recovery mode but you need to have phone rooted.
Note though that Froyo uses 3e and I've tried to use update zips, wont take without going down to 2e recovery.

Warning etc I take no resposibility if you break something etc
First of all fix your 3 button for recovery, there should be some guides around here.
1. Try that superoneclick you posted the link to. If it wont work it wont work... But it will.
2. Recovery you need only if you want to tinker with the rom a little more and to do nice stuffs like backup. Or for a recovery
Oh and I am on stock rom + custom kernel + another modem and happy with it.
First I was rooted and the rest was as it is and I rooted with the super one click root . Dont forget USB debugging on. Once you root though I think wont be long till you start customizing a little . Good start is a nice good custom kernel
If you want to stick with stock you could try these stock roms which come pre-rooted, zip-aligned and deodexed (making them smoother and allowing the application of themes).
http://forum.xda-developers.com/showthread.php?t=948790
To fix the three button combo have a read of this thread. The OP of this one is really helpful if you're not sure what to do. I had to do this and it was the most nerve racking thing i've done to my phone as if this screws up you'll be sending it for repair.
http://forum.xda-developers.com/showthread.php?t=821698
Thanks a lot to all of you for your answers!
Had my first successful flash today (3 button combo mode) and will now take a more in depth look at rooting etc.
So far, I feel more comfortable to try a rooted stock kernel maybe instead of superoneclick.
However, if I had to unroot for any reason, how can I do that if I flashed the kernel?
The way I understood about ROMs and Kernels is that ROMs already contain kernels. So flashing a stock ROM would get me back to a stock kernel and the phone would be unrooted again?
you can also just flash a kernel and root such as cfroot or speedmod..

To un-root you can just flash a stock ROM (look in the general section to find them).
If you like stock ROMS then like the person above stated you can just flash a pure stock ROM then flash a new kernel (i.e. speedmod, voodoo etc.).
Good to hear the 3-button flash worked for you, now it is very difficult to brick your phone as you should always have the 3-button download mode which enables flashing with Odin.
Just be careful when picking a stock ROM, especially if its new, to check if it includes a new bootloader!!
Thanks all again!
and good on you for being sensible enough to get a jig.....best fiver I spent in ages. Every time I flashed back to an early stock it trashed my bootloader.
no worries about flashing now

Mate if you just want a simple to apply root access I would just use Z4root... its not used so much anymore but it works well and can be installed by just installing the app(can't be obtained from android market, internet only)..
Link: http://forum.xda-developers.com/showthread.php?t=833953
otherwise you can just use Odin to flash CF-Root ( I do this all the time on stock firmware and works perfectly every time).

I used z4root on 2.2 but afaik z4root no longer works with 2.2.1.
I did flash the CF Kernel now and quite happy with it so far.
By the way, is it a bad idea trying to flash with Odin if the phone is connected via a USB hub instead of connecting it to the direct usb port? Each flashing failed on the 1st attempt (worked on the 2nd), no matter what I flashed so far. Some searching here indicates a hub is not recommended.
If that's the case, why is that not mentioned in all those read-me-first guides (or maybe I missed it somewhere)? Not every first-flash user will have a JIG at hand.
You're right you should have the USB cable plugged into a USB port on the motherboard (not a port in your pc case or a hub) for the least chance of flash failure.
Not sure why though tbh, I think it may have something to do with the Samsung USB drivers that get installed with Kies being a bit flaky.

[Q] Docomo SC-02B 2e recovery and CWM

I have the Docomo version of the Galaxy S, SC-02B running 2.2.1 OMKA5 build. I have rooted the phone via Superoneclick. I have read through many posts but I have not really found a solid process or even if it is possible to get 2e recovery and CWM without having sim card or modem troubles.
Also, to my knowledge custom kernel and rom flashing cause similar issues. I would really like to do more with my phone, so if anyone has had stable success could you please post your method?

Follow this link if your not a Japanese reader use Google translate http://komugi.net/archives/2011/03/07104838.php
Thank you, I appreciate the response. I can read Japanese I will check it out and get to testing it out. I am surprised for the SC-02B being most popular phone in Japan, from what I have noticed not too many ppl are really doing much past rooting
Boo, he/she is basically confirming the same issues that the users on this forum encountered with their s-02b's.... Summarized from him other than getting 2e recovery on the phone, it does nothing
Actually you can have clockwork it is just inconvinient because it takes two steps to get to clockwork instead of one. Once you have 2e just download rom manager and your off and running. I'm doing nanodriod backups almost everyday so I can recover after I've failed to make a theme work or screwed up the phone in some other way. The big problem is their are no Japanese developers work on our phone and the other dev's are reluctant to develop for a platform that they don't have to test on.
According to that link the person said Rom manager didn't work...
If it does, than be able to make nandroid backups would definitely help me out a lot. Did you use his method to get 2e recovery, or another?
I used a different method but the results are the same. Can't find the link to the one I used. When he says it doesn't work I think he means that ROM manager doesn't boot directly into clockwork it boots into recovery and then you have to apply an update zip that puts you into clockwork the very first time you do it doesn't work and you have to apply it a second time. This is clearly explained somewhere deep in the ROM manager thread.
In his post shows clockwork running and mentions how long it takes to do the backup if your running OCLF.
Thanks for helpful information.

[Q] Need help with ROM Manager

Hi Everyone,
I bought ROM Manager Premium v4.5.0.1, in order to do a Nandroid backup on my I896 running stock I896UXJL1.
I ran "Flash ClockworkMod Recovery", and it said my Current Recovery 2.5.1.2 was the same as the Latest Recovery. So far so good.
Then I ran "Backup Current ROM." Instead of doing a backup, it rebooted my phone into Recovery "3e" every time. I tried it many times and got the same result.
This is so confusing. For whatever reason the app decides to boot my phone into recovery instead of doing the backup, I would expect it to at least go into CWM Recovery instead of the stock 3e.
Questions:
1. Has any of you gotten rebooted when you try to do a Nandroid backup?
2. Has any of you gotten rebooted into stock recovery even when CWM is installed?
Thanks.
KK
In general ROM manager is trash for SGS. Don't bother with them. I would say find a kernel with CWM cooked in it but JL1 is a rogers only and I don't know any for that.

froyo wasnt so damn kenel picky. any froyo kernel will work.
Doesn't work with any ROM
I've tried ROM manager after flashing KH3 and KJ3, and the "Reboot into Recovery" still doesn't work. I get the triangle-exclaimation-droid screen with nothing else, and it stays that way until I use the 3-button reboot.
Since the app can't even perform one of the more basic functions, I am afraid to let it do anything else. I wish I hadn't paid for the premium version.
ROM manager doesn't work on Gingerbread..... Rom manager isn't very good for Samsung phones

Stop what you are doing and read. ROM Manager sucks basically. Very few people on here actually use it. If you keep just throwing things at your phone though without knowing what you are doing you are going to end up with a shiny, expensive, paperweight. Then you get to spend upwards of 50$ getting that fixed. So please, for me, the forum, and your phone just read. Or at very least ask a directed, detailed question. As in: my phone is here, im trying to get to there, this is what im doing and this is where and how its failing.
Flashing using an app
I actually did weeks of reading before flashing my phone for the first time. I got scared by potential problems such as USB interruptions.
This is where I am at: I've been using mostly Odin to flash. I have successfully flashed KH3 and then KJ3 (with KF1 bootloaders and Boog's kernel); however, I am still nervous each time I do anything.
This is where I hope (or used to hope) to get to: I keep looking for a way to minimize the probability of human errors and technical hiccups. (It's a habit I've picked up while working as a software manager.)
I went for ROM Manager because the same developer wrote CWM. I do appreciate you guys sharing your opinion of the app's effectiveness with the SGS. I only wish I had been warned sooner (ideally by the app's developer).
Find ODIN packages that don't inlcude bootloaders. That will only minimize your risk to soft bricks wich can be recovered with a jig that are easy to make and only cost ~ $10 if you choose to buy them. I personally use KH3 as my "stock" setting when I need to flash to stock. I use Cezar's KH3 .tar that doesn't include them but there are atleast 1 1 click around.
CWM for Captivate Gingerbread UCKJ2
Sorry in advance for the noob question. I have read many posts but can't find my answer. I've installed the leaked gingerbread rom from Samsung called uckj2. I was trying to change the modem by flashing a zip file using clockworkmod recovery. I've heard the way to do it is by using a kernel that already has cockworkmod already baked in. Which kernel should I use?
Thanks in advance
KJ2 have 3 kernels that should work. Corn kernek, Samurai and Boog's kernel.

[Q] Rooting my captivate, can't copy root file to phone

Hey folks. I'm bailing on Gingerbread because it was causing me too many problems. I'm trying to get back on Firefly 3.0 and I'm stuck at getting the phone rooted.
Whenever I try to copy the Root.zip from the AIO folder over to the phone's root folder, I get an error about the parameter being incorrect. I'm not sure what to do at this point.
Use Fugu root? Easier.... Also depending on what Gingerbread you are on there are kernels that have the root scrip baked in them.
^ you misread he's not on gingerbread, he wants to flash firefly.
You don't need root to flash a ROM. Odin a kernel that has cwm baked in. boot into recovery and flash the ROM.
Thought he was on GB trying to get on... you know what ya I missread. @OP do what Studa said xD. Wonder why people think they need root to flash roms..... I blame Rom Manager.
I know I don't need to root the phone, but in order to get certain things done on the phone, it's necessary.
I'm actually at a wall right now. I used SamsungCaptivate-SGHi897-UCKB2-Rooted-One-Click which successfully booted my phone to ATT 2.2 firmware, but I can't get any Odin to pick up on it now. I've tried five different Odins.
At this point, I think once I get the phone up and running on Firefly, I'll be walking away from flashing until I get another phone. Then I can use this for testing, etc.
On a side note, before I started this project yesterday, my modem was messed up. Now it would seem I have a successful connection to wifi, which I couldn't get.
As great as that is, I still can't get Odin to pick up my phone. Any thoughts?
Was that kb2 package heimdall?
If so you have to uninstall the heimdall driver and reinstall the Samsung driver.
Either way I would reinstall the Samsung drivers but it is a must if you used heimdall add the drivers conflict.
Alright. That's done, but I'm on I896UXJL1-stock now, and I'm pretty sure in doing that through Odin 1.85 I unrooted the phone. Correct me if I'm wrong. That's why I used the ATT stuff, because it auto-rooted the phone.
So it would seem I have some issues to work through. I can either root my phone and be stuck with ATT firmware that I don't want, or I can unroot the phone and use Rogers stock and hope for the best with Firefly.
This is by far the most confusing computer-related issue I've ever worked with. There's too many options to play with and they all work differently.
Why would you be stuck on at&t firmware? Why do you need to root before flashing firefly? Why don't you root Rogers stock?
you're confusing everyone involved lol
Okay, so maybe I'm a little in the dark on the rooting issue. Basically, I'm going back to Firefly because I thought it was amazing. Fast, responsive, and no issues I can think of on my phone.
I'm rooting the phone because it's my understanding that in order to spoof my location in order to get certain apps (Google Music), I'd need to be rooted.
I'm having a hell of a time trying to get this done, and my biggest problem, to reiterate, is that I have about fifteen different Roms, all either ATT or Rogers, three different Pit files, and so, so many Odin programs.
I'm now on 2.1 with that Toronto stock firmware, in order to work around the 3e error in recovery mode when trying to put on Clockwork. Unfortunately, now I'm getting some other error in regards to the Update.Zip file, Status 7.
I apologize for confusing people, but I promise I've read as much as I can about the tools I'm using, but I'm running in circles, flashing back and forth trying to find solutions.
you do not need to root before flashing the rom. it will be rooted after and then you can do what you need to do to get your apps working if you need to (firefly contains canadian locale cause its based off of rogers froyo firmware) changing stuff before you flash so apps can work is a waste of time as the flash will overwrite the firmware you just tweaked.
now, since your on eclair i'm attaching an update.zip that contains cwm, put it in the root folder of your sdcard boot into recovery select reinstall packages twice and it should boot into cwm where you can then flash firefly.
You're a frickin' genius, Studa. Don't let anyone tell you otherwise. I've got Firefly on thanks to that Update file, and I'm getting the ball rolling on everything else. If I wasn't so broke, I'd donate, but I hope my thanks is good enough. I really appreciate the help. It cut through twelve hours of stupid.
