[Q] JH7 Odin?

Ok, so I have Froyo on my Captivate from a looong time ago, but now I want to put in Andromeda 2.0. I followed the directions but then it says i have to get back to stock firmware. I got my Captivate on October 25, so it had the JH7, so now I need to get back to that firmware. Anything before that would brick my phone, so I'm trying to find an Odin restore that will get me back to JH7. And yes, I have googled it up a lot. Could you tell me or post a link, where I might find it?

1) Wrong section
2) You really do not need to go back to stock, that is just a disclaimer used. If you understand you have the possibility of bricking your phone than just flash the ROM. I will help you search but if you search the Dev forum rather than google you will find the thread for JH7 Odin. The only time you really need to go back to stock is with a bad flash, which sometimes can be fixed by flashing the ROM a second time.

Ok thanks, sorry for the wrong thread I'm just about to do the Andromeda 2.0 now.
Also, so it doesn't matter that I have the leaked 2.2 firmware, I can still download it with that rather than the 2.1?

yes you can flashhhhhhhhhhhhh if you don't make your phone into a paperweight

I got a replacement 1010 with jh7 installed and had no issues using the odin ji6 one click restore on it.

Write lets get since information in here...
No technically you do not need to go back to stock but it is always a good idea. No matter what phone model or what stock it came with going back to jh6 is the best bet. It is the tried and true method and better then jh7.so just use the normal common odin

You could just flash over but the thing you would have to get past is 3e recovery there is a fix for that. I think there was a time when all new roms in xda were based on official 2.2 software back in october and november of last year and it had 3e, and the easiest way to get past it was to flash stock first. also there are two versions of odin you should try to get familiar with and a recently updated wiki sorta thread should be useful for up to date info. Hope this helps.

Go ahead and bring it to stock + update to Froyo.
Also, so it doesn't look so weird, use it for a couple days so there's data and cache lol

lol yeah probably a good idea. although i hate the idea of running it stock for more then 2 minutes

Running it for a few days and adding froyo probably not necessary. I would reformat my phone to stock in order to remove all personal data before i send it in.

i was thinking the same in that most people would factory reset before sending phones in but i was thinkin froyo might be smart because it would be 100% stock then im not sure if our 1 click stock is 100% in their eyes

Idk how much they actually check it - I assume it's kinda random so I wouldn't take any chance.
Odin3 one click does bring it to stock but having Froyo might look better and show that it wasn't just brought back to stock (along with some cache and data).

While we are on the subject, IS there a 1-click for Froyo (stock)? I ask because i've been hearing rumors of it, and i just havent had the time to investigate.
If there WASN'T a 1 click stock (froyo) then disregard my question. However, does that mean the only way to upgrade to Froyo (stock) is through CWM? I know people have been doing it through Kies, but i'm not a big fan.

Idk if there is but tbh it wouldn't be so useful as 2.2 as recovery problem which requires 3e recovery fix so makes flashing more painful.
There's although Odin 1.81 which you can flash Rogers (I896) version of Eclair (duno if there's one for 2.2 - haven't really looked into it as Kies mini works well)

Thanks!

there have been several threads on this
ODIN ONE CLICK (and the other) CAME FROM SAMSUNG
so YES the odin one click is STOCK. ITS WHAT THEY USE to refurb ATT phones.
there has been no ODIN one click 2.2 leaked to the net.
we dont have the source code so we cant update the 2.1
how much do they check your phone? very little. the internal guts to replace at their cost is less than 50$. They have dozens of phones from each different model come in every day. They have about 10 minutes to hook it up to a machine that runs hardware tests for them. then it gets gutted. It is not worth their time to *see* what is on the phone. They only care if it works or not. so they can move to the next phone in the bin.
stock 2.1 is fine if it came with 2.1
2.2 if it came with 2.2. there are CWM 2.2 upgrade flashes available. use rom manager/ the update.zip method of CWM to install 2.2 then delete the update.zip and rom manager app.

Not necessary. Just odin and kies.
I would master clear anyway if I were stock. Just go back to stock, update froyo and that's it.

If he flashes 2.1 (JF6), couldn't he run the software update to get JH7?

Help on analyzing brick

Hey guys I hard bricked my captivate and need help evaluating what I did wrong so I can prevent it from happening in the future. I just received the device in the mail (it was a replacement device) and tried to use odin one click JF6 to flash it to eclair. I've done this process 100's of time with my previous captivate but with my new one I saw that it was hanging at sbl.bin and my device turned off. I unplugged the usb, did a battery pull, and used my jig and the phone went into download. PHEW... Thinking that my JF6 odin was corrupt or something I decided to use Odin One click JI6 and the odin hung again but this time I wasn't so lucky. The phone wasn't showing any thing and the jig was infective. The phone hard bricked. My question is how did I brick it and why did it hang when I tried odin one click,. (Odin one click has always worked flawlessly for me in the past). Also are froyo and eclair bootloaders the same? If were to flash JF6 2.1 eclair using odin3 over Rogers Froyo should that work?l (BTW my device is 10.11 build)
edit: I understand that odin one click always has a risk involved because your flashing boot loaders but I just want to distinguish whether it was just an unlucky odin flash or something to do with the build number. Thanks

thats a good question. As far as I know Froyo and Eclair have the same bootloaders, but as far as the Odin problem- im sorry I have no idea.

A lot of people on here have bricked their captivates by using OneClick Odin. What happened was that your replacement captivate came with stock froyo which does not work with OneClickOdin. You were on the right track by going to stock JF6. Not sure why it failed for you but if you would have tried it again I'm betting money it would have successfully flashed. Sorry to hear about your troubles.

Yes search for other threads about oneclick NOT being cooperative with newer model captivate sthat came with stock froyo. I said he was on the right track because the correct method to go back to stock is JF6. Which can be found in Icezar1's continuum thread which requires odin 1.3, the pda file, etc. If he would have simply tried the JF6 process again it would have completed rather than using 1 click odin and messing up everything. Read the second post of this thread where ZELENDEL says that newer captivates with froyo don't work with oneclick

First of all JF6 is NOT a "method" of going back to stock. JF6 is stock firmware. And I could be wrong but I thought icezars program gave you
Stock firmware 'JI6'? I'm not next to my computer so I do t really know off the top of my head.
*EDIT* Your right, icezars1 program is JF6 firmware. However it is only given as an alternative. Even states in his OP the only reason why Odin3 Oneclickdownload would not work would be because of an unreliable USB driver. So this is indeed a safer way to get back to stock JF6. Odin3 one click should work too. It's unfortunate that it doesn't "always" work.

I'm sure you understood what I meant when I said JF6. It is certainly a rom and the process mentioned in Icezar's thread is one of the preferred methods of downgrading a newer model captivate that is on stock froyo. Let's hope that we have answered and clarified all questions for the OP.

i actually didn't understand what you meant. You make 2 refrencses to using JF6 as a method. First you said the correct method to go back to stock is "JF6", then you said the JF6 process. Again...both refrences to a single JF6 method, when that is not the case. Both methods used to get back to JF6 stock firmware use Odin. One is a one click program, the other a manual flash using .tar.md5 file.

Duuhdave, if im on stock froyo (im in canada btw, so rogers) and use cezars method of flashing stock firmware through full blown odin, should I be flashing jf6(i897 2.1) or rogers 2.1? I ask this because ussualy they want you to on jf6 before flashing.

As far as flashing to stock with Odin 1click from stock Froyo, it has worked fine for me MANY times. Bricking using the odin 1click may be related to build number. I went from a 1007 (with stock 2.1) to a warranty repacement 1008 with froyo stock. I flashed 2.1 without a problem, and have several other times.

Using Odin 3 one-click, and icezar1's stock rom will both take you to I-897 AT&T stock JF6. If you want to return to Rogers stock 2.1 without flashing bootloaders, use TRusselo's Rogers Captivate Stock ROMS no ATT logo!.

Thanks for the help!
Sent from my SAMSUNG-SGH-I897 using XDA App

its the build number that caused it

More than likely it was something about the phone having stock froyo with the 3e recovery. I have never had the issue with any of my 2 captivates 1007's and wife's 1010 build but they came with stock eclair. I know many people have had issues due to the stock froyo with 3e recovery as why there is a modded 3e recovery how to somewhere on this forum. Since he laready had froyo boot loaders it has nothing to do with that, and either was a fubar flash due to 3e recovery, bad USB cable, etc that messed things up.

This happened on one of my old cappies that i got replaced. It was a 1008 build. It's an error in the efs folder. Did you make a backup of your efs folder before you started flashing?
If you didn't here's a method that worked for me that might get you back to normal. What i did was use Kies mini to upgrade to stock 2.2 then make sure the botton combos were working (vol up+dwn/plug usb to get to download mode, and vol up+vol dwn + power to get to recovery.) If those are working, now flash back to stock using Odin 1 click.
This wokred for me. hope it helps.
If you have your original efs folder, use Root Explorer to place the original folder ni place of the current one while on stock 2.1, then reboot to see if it worked.

What Gingerbread Roms did you "play" around with, I'm guessing you used the I9000 bootloaders also?

Your going to want to flash back to eclair (imho) or froyo if you'd rather, but it will have to be done through odin without a 1 click method. If you know what I'm talking about all good. If not lemme know and I'll help ya to the links, cleaning the kitchen atm but its all good

Op if everything works after you rom it and you have no plans to go to stock does it matter?
It could just be how the phone acts with the jf6 modem as its a signal problem...
And what exactly are you doing when trying to master clear and what happens?

Couple things for the Master Clear
1. Make sure to shut down Odin then restart it without the phone connected
2. If that doesn't work restart your PC
3. If all else fails, root, install ROM Manager, get into CWM and do a factory reset
Like Studacris said, Odin to JF6 flashes the proper bootloaders, so you dont need to worry there. I've done it TONS of times
Edit** Are you using this Odin?
http://www.mediafire.com/?0w2y31maz8mdom4 If not, I would HIGHLY recommend using it

Ok, but that would be a good thing, you can just use the signal problem as an added reason for sending it in. If you can flash stock and it boots, all is well. Anything else just goes in your favor of why you deserve a new one.
Plus, if the phone stops working to the point it does not boot they will have no real way of telling what was running before, nor will they waste the time to find out. It will get tossed into the re-write pile, and go thru the paces for becoming a referb.

You do realize that the phone has to be regularly on to do a master clear and not be in download mode right?

One click gingerbread question

So I accidently bricked a build #1010 phone using oneclick to revert to stock, not realizing it wasn't compatible. I found this today on XDA:
http://forum.xda-developers.com/showthread.php?t=1127249&page=29
My phone currently is build 1009, got it through a warranty exchange, came with froyo pre-installed. Is it compatible or will I brick trying to run? I am also aware of the recovery and the "unsigned packages" thing...do I need to change the recovery first before I run? Thanks

You would brick if you went to 2.1, but that is totally compatible! Have fun and. After flashing that go look for. Stock KH3 and you have to flash KF1 then KH3. Just a min I will link you to everything.

Thanks for the quick response! Yes my previous phone was build #1008 and I ran oneclick several times on it with no issues. My wife made a warrenty claim on hers, and I thought i'd be nice and install cog on it, and I couldn't get the recovery to work so without even thinking about it I ran one-click on it, and I bricked it. Honestly I had no idea what build number my phone was back then, but after the brick I found out her new warranty exchanged phone was build #1010
Ever since I've been deathly afraid of running anything with bootloaders. When my speaker died on my original captivate I didn't run one-click, instead i used Odin3 and found a CWM flashable eclair rom, and ran that instead, and then used kies mini to go to froyo. I've had my newer captivate since July, and been running stock since, getting sick of all the issues it has, none of which i noticed in cognition. I actually logged on to get Froyo Cognition, but the links are all broke to it, so I figure I might as well try gingerbread out.

I'm on KH3 stock right now and its great! And it's the GB bootloaders that fix the 3button fix, no need for eclair bootloaders since they are backwards compatible!

Well I'm pretty sure it was hardbricked. It wouldn't do anything, no 3 button, no trick anyone suggested to try, it just stayed black and unresponsive.

Nope nothing. Basically half way through it just stopped responding and i eventually gave up and unplugged. It wouldn't do anything. It happened to a friend of mine too but luckily for him when he pushed the power button he got the warning sign on the screen. My phone was completely dead and wouldn't respond at all

all you have to do use the odin one click to go back to stock which is jf6 then use odin 3 and you can goto kh3. no other flashes are needed. ive done it this way 10 times and no bricks.
