Here are the details of my tab
Firmware Version: 2.2
Baseband Ver: I987UCJK1
Kernel Ver: 2.6.32.9 [email protected] #1
Build Number: FROYO.UCJK1
Carrier: At&t US
So I managed to root my device using Superoneclick but I'm having trouble running clockworkmod because of a package verification error. I've realized that I need to upgrade my kernel to make it work. But I'm having trouble finding the right kernel/rom. I'd prefer to flash a new rom using ODIN but I'm unable to figure out which rom to use. Can anyone suggest me a rom to choose? I'm confused by jk,jv,ja terminology
Flash the rotohammer JME version 4. Then flash chainfire cf root to get CWM. BE SURE TO USE FROYO VERSIONS NOT THE GINGERBREAD VERSION.
I believe AT&T is a GSM tab, uses a sim card, so any GSM roms will work. If its doesn't use a sim card look for the CDMA roms.
I would suggest upgrading to gingerbread as that works really well.
The best advice I could give is read any guides on updating REALLY well, go slow, doublecheck what you've done and DON'T skip steps because you read through already.
If you want to keep all your Contacts, Apps ETC... then backup with Titanium Backup before you flash as this will clear it out...
GSM ROM
Go here - http://forum.xda-developers.com/showthread.php?t=888071 it will give you an app thay allows you to check your bootloader.
You may have to go to settings>Applications>unknown sources needs a tick to install.. This allows the installation of 3rd party apps using file manager. Run the app, it will tell you if the bootloaders are locked or ask if you want to unlock... Use at your own risk...
So saying, this was the first gingerbread rom I flashed - http://forum.xda-developers.com/showthread.php?t=1073854
Instructions were - Procedure (ODIN !):
- Download and extract the firmware zip
- Download and extract the attached gt-p1000_mr_PIT.zip
- Download and extract the attached dbdata.zip
- Flash the firmware tar as PDA, repartition enabled, use the attached PIT
- After flash immediately boot into download mode again - wait for it to go to the samsung LOGO here as a whole heap of writing goes up the screen then it reboots. DO NOT TURN OFF UNTIL IT REBOOTS TO THE SAMSUNG LOGO...
- Flash dbdata.tar as PDA (NO repartition) in ODIN again.
- After flash immediately boot into recovery mode
- Wipe cache
- Wipe data / factory reset
- Wipe Dalvick cache
Then flash this in ODIN - http://forum.xda-developers.com/attachment.php?attachmentid=593112&d=1305133135
This will root your device.
I then updated to this - http://forum.xda-developers.com/showthread.php?t=1074759

Added this set of instructions, it has pictures, remember there will be some differences... - http://forum.xda-developers.com/attachment.php?attachmentid=596770&d=1305467639
Before you flash anything, kindly check if you have protected/locked/signed bootloaders.
Thanks for the quick replies guys. Do appreciate it. So regarding the bootloaders, what should I milk for?signed, secured??
Just a comment about the procedure above.....unless you have CWM you will not see an option for dalvick cache in the default recovery,at least for mine the last entry was for cache-no advanced features like battery wipe and dalvick......

Hello,
I am completely new to flashing roms on android devices and i am just trying to understand the basics behind the process.
- Installing custom roms
- reverting back to stock firmware after installing a rom
I read the 4th post in this thread : http://forum.xda-developers.com/showthread.php?t=991792
i kinda have some understanding about flashing roms now but i still dont fully understand it.
My device is a Samsung Galaxy S i9000.
Thanks
What exactly do you want to know?
1. Installing custom roms is pretty easy the hard part is choosing the rom and to flash a rom you need to have the cwm recovery and like be on the base you need. ex: lets say you are on a jvt rom and you want to flash a jw1 rom, well in this case you dud need to flash jw1 from odin and then flash the rom from recovery...., but if you are on a jw1 custom rom, then in that case you can just flash the rom from recovery with wipe (recommended).
2. To flash back to stock: you dud need the stock file from sammobile or from wherever you get it and you would need odin, you place your phone in download mode then you put 512pit in the pit section/ code in the pda section/ modem in the phone section/ and csc in csc. then you have to make sure that repartition is ticked and all the others. make sure that the download is not interrupted for that would brick the phone.
-to flash a kernel you dud need to put the tar file in pda and Don't check repartition and click start.
I hope this helped a little
and remember to do this at your own risk.
Sorry for the noob questions but im just trying to understand haha
1. what are jvt and jw1 roms?
2. When you say be on the base you need do you mean the base firmware required for the rom?
3. How would i know which rom i have now, JVT or Jw1?
4. Whats the thing u mentioned whipe in "you can just flash the rom from recovery with wipe (recommended).?
last.5. I already found the stock firmware i have now and ive downloaded it for later if i need to restore it. but what is the tar file you mentioned in the end?
Thanks Man. I appreciate it.

sorry, this is not meant to be offensive but you have a lot to read. There're some good tutorials on how to flash your phone here on xda. search for it.
short answers to your questions:
1. jvt or jw1 are versions of stock samsung roms
2. I think he means if you are on a jvt rom you should only flash custom roms for jvt
3. settings>about phone
4. wipe means resetting the phone, deleting cache and dalvik-cache
no matter what u know u first should know about flashing stock roms..in case u mess something up u will need to flash the stock roms,its a good thing that u have already downloaded these..then u should know how to install kernels to root n have Clockworkmod recovery,then u will be able to flash custom roms..u should serach the net for these questions with a 'How to' at first...
Instruction for new ROM installation
There are basically 2 methods for flashing a ROM
1. CWM recovery menu mode
2. Download mode.
1. For CWM recovery mode you phone must be rooted with CWM, just put the ROM zip file in sdcard of your phone of your choice. then power off the phone. Then you may want to boot in reovery mode for this use pressing and holding 3 button combination simultaneaously as Volume UP + Home key + Power key now you should be booted in to recovery mode there just wipe data/factory reset then wipe cache from option then find and select install from sdcard -> chose file zip from sdcard and press power key to selct and start flashing. wait max 5 min and your phone will be booted with new rom of your choice.
2. Boot in to download mode by pressing and holding 3 button combination simultaneaously as Volume down + Home key + Power key now you should be booted in to download mode now connect your phone with PC and open odin in PC then select ROM file as PDA, PHONE & CSC under propoer boxes then click start - wait max 5 min and you phone will be booted in to new rom.

But I could not find out the way.
Even I checked Kernel Version, LA2 there is no way to root.
Finally, I think my phone is a kinds of Not Directly ROM.
So, I will downgrade my ROM.
Before that, I would like ask if there is anyone who succeed to root this model.

hi gang.
I have a bone stock gn 7000 in the US on ATT.
my kernel and build is XXLA6.. baseband is XXLA4
I plan on using PC Odin to flash the German ICS.
I've already installed Kies and PC Odin recognizes my device.
I have been told to do a 'nandriod back up' first..
And been told That I need CWM first to do this nandriod backup.
Can anyone tell me "how to" get CWM on my phone?
where to get the software and how to install it.
And finally how to do the back up.
I'm green as grass and have never flashed before anything
thanks for all your help.
all replies are.welcomed and encouraged.
thanks again.

thank you, david
I've been all over your first link a few times before.
I've seen no clear and direct link to CWM and intructions to CWM only... without root.
I don't believe that I need root or do I?
I just need to to a nandroid back up.
I believe that my rom XXLA6 is non rootable anyways..
I only need CWM only and cannot find the software and instructions.
and your other link covers the 9 inch tablet...
thanks again
A NANDROID is a master backup tool which is available through the CWM Recovery's "backup and restore" menu. It stores everything in the ROM except the kernel. It's more like this analogy: a photograph which captured the exact state of your ROM, apps and all at the moment of backup. It is recommended in case of emergency and in case you need to go back to the latest working ROM. How-To section below.
You need CWM Recovery for this one. Once you're in CWM Recovery, the process is straightforward. Look for the "backup and restore" menu, access it and you will see two options: "backup" and "restore". Select "backup" and wait until the system gathers all data and packs it as a backup located in your internal memory, inside a folder called "clockworkmod".
For restoring the process is the same. You need to do the following to ensure a proper restore and prevent issues that might pop up: Wipe your system using CWM Recovery's "wipe data/factory reset" and after that go to "advanced" and now "wipe dalvik cache". Now go to the "mounts and storage" menu and select "format /system". That was a full wipe. Now proceed to the "backup and restore" menu, select "restore" to select your backup. Remember to reflash the kernel if you had one that didn't come with the ROM (like _motley's for example). The linck of tablet is used to know what are the permissions of root end CWM recovery...
Again, David thanks for your response. You seem to be the only one willing to help..
I do believe that you are missing my point..
"I need CWM ONLY". I need the software and instructions to install CWM only.
Your links and your instructions do tell me what to do once CWM is installed..
BUT.. HOW TO get CWM in the first place??
Once CWM is on my phone.. then yes.. I can use your instructions.
BUT FIRST... I need to install CWM on the phone..
Can you tell me HOW TO get and install CWM..
We have to start at the beginning..
Where to get CWM ONLY... How to install it (CWM)?
Ive given thanks again.. please help with the first steps in this process..
I dont want to brick just trying to
INSTALL CWM
only then I can use your instructions on what to do with it..
FIRST I need CWM....
HOW to get CWM on the phone is the question.
thanks alot

Flash this from Samsung recovery (Volume up + power + home). This is an extremely unstable kernel. DO NOT WIPE ANYTHING from this kernel. ONLY use this version of CWM to install a safe GB or ICS kernel first. After this, you are free to flash anything you'd like.
The simplest way to get CWM and start flashing ROMS.

my father has a stock samsung galaxy tab (p1) running the horrible android 2.2 with touchwiz all over it
he asked me to update the device so it can run ICS
i've done that with my SGS1 which was easy, but now i have a problem.
when reading the guide for installing cm9, its says "This guide applies to a Samsung Galaxy Tab (GSM) on the stock 2.3 release"
my sgs1 was already running 2.3.4, so i just followed the instruction and that was that, but my fathers tab is stuck on 2.2 and has never been rooted or anything
my question is can i simply just apply the steps or do i have to update the device to 2.3 and then follow the instruction
i cant afford to brick the device or i'll never hear the end of it, he love his tab as if it was his child or something
PS. I've learnt how to root the device using (superoneclick) and i've also found how to flash CWM on it, can i do that and then flash the CM9 Rom to it.
im sorry if missed a similar post somewhere but im still a noob at this and i really wanna do it (froyo + touchWiz is a recipe for a crappy device :silly: )

Stop there and you will have Gingerbread
But since you want ICS, continue reading the guide.
- download ICS (CM9 or AOKP) and gapps-ics and put in external sd card.
- boot to download mode
- you need to use Odin to flash Overcome kerner tar
- once flashed the tab reboots.
- ignore the robotic voice, just force the tab to off
- boot to CWM recover (press vol-up and power )
- flash ICS (CM9 or AOKP)
- after flashing the system will convert your tab to MTD partition, but it will probably bring you to recovery or stuck at boot.
- force reboot to recovery again
- flash ICS again
- immediate after complete, flash gapps

Hi, yes, same thing as before
use the guide, start from page 7 where the Odin screen shot is
GB-stock-safe, with pit file selected and "repartition" ticked.
But hang on, you are from middle east.
Do you have wifi cut out when a SIM card is inserted?
That is a known issue with middle eastern tab due to some wifi country code, that affects all Android 4.0
But I could be wrong, you may not have the issue.

Back to stock usually solves most issues. Please check your IMEI number given in the About Device page (do not post it here) with the number printed in the back of your phone to see if they match.
IMEI numbers match. Thank you for your reply.

@wnb_jr: Take a look at this sticky thread for a flashing guide, and attached to Post 1 is the Odin software you would need: [Stock ROMs](OneClicks Master Collection)+[Kernels (Stock & w/ CWM)]+[Modems] UPDATED. Links in my signature I would recommend following: Stock GB ROM+ Kernel, Modems. The ROM and Corn Kernel are Ginger Bread stock release KK4, and the Modems sticky thread has a link to a map where users tag which modem worked for them and in what area. And as always, have fun.
Quick version flashing to stock (mostly):
1. Download "I897UCKK4 Odin One Click - Stock, NO Bootloaders, Re-partition, Full Wipe" and extract. (Stock GB ROM link)
2. Follow instructions from 4-2ndtwin contained in the txt file to flash the stock rom.
3. Download "Odin3v1.85.zip" and extract. (Stock ROMs OneClicks Master Collection post #1)
4. Download Odin flashable version of Corn Kernel 7.06. (Kernel link)
5. Run Odin3 v1.85.exe. Load Corn kernel into the PDA slot of Odin. Connect your phone in Download Mode to your computer, wait until Odin recognizes it, and click Start. When Odin displays the big green PASS, disconnect the micro USB from your phone.
6. Reboot your phone into Recovery (typically holding down three buttons Volume Up, Down, and Power until the phone reboots, then when you see the initial splash screen come up let go of the buttons). Navigate the Recovery menus and find the option to Root and install SuperUser.
7. Profit. Now that you're back to Stock with root and SU, you can go anywhere from there- flash other ROMs if you want (now on you can flash them through Recovery instead of Odin). Backup options in Recovery are referred to as 'Nandroid backup'. Recovery is also known as CWM or ClockWorkMod recovery. If necessary check out the Modems thread. Any issues connecting your phone may be answered in 4-2ndtwin's thread Captivate - PC Connection Issues, Download Mode and Recovery Mode Help.
