[Q] Q: How do I install a kernel?

I am trying to install 2.5.4test4 kernel. Is there anything special I need to do like I did for the root and rom installation??

Nothing special, just boot into ClockworkMod Recovery, flash from zip and select the kernel zip on your SD card!

thankkk youuuu

I usually wipe just the dalvik cache under the advanced setting in cmw too. Seems to cut down on the bugs I run into.

It's common sense, but make sure you do a nandroid backup before you flash anything.

+1 on the backup and wipe. You dont have to clear data.

[Q] Full wipe before flashing backups?

Do I need to format / wipe anything in the CWM screen before restoring a flashed backup?

This is my personal procedure evertime I install a new rom, or revert to a saved backup. I am a noob, so I don't know if it's necessary, but I do it by habit now, and it seems to work for me.
1.wipe dalvik (in advanced menu)
2.wipe cache
3.wipe data/factory reset x 2
4.wipe system (in mounts and storage menu) x 2
5.(optional) wipe dalvik,wipe cache
6. Install zip or backup depending on what my intention is
7. fix permissions
reboot
edit: Actually, this isn't "MY PERSONAL" procedure...this is what was recommended to me from other valued members of this forum. I have simply adopted it into my routine.

That's a whole lotta wiping... wont hurt anything but very redundant.

I thought dalvik couldn't be wiped in Recovery- it gets an error message.

I have external recovery... I haven't updated CM maybe it will take care of it... could it be an SD card issue? I mean I haven't seemed to have had any issues... dunno...

It depends on what the backup is. If the backup is just an older version of the same rom I will just flash right over sometimes. If you are trying to restore a gb rom over a froyo, you will have to wipe first. Any time you are in doubt, just wipe.

I get the same path error to sd-ext. I've wondered what sd-ext even is, there is nothing in it and it is not my external or internal memory because they are in different directories.

Wiping dalvik & cache and all partitions except sd card.

Is it correct that you wipe all partitions except sd card and dalvik & cache before you install a new Rom.and after the Rom is installed do you wipe the dalvik & cache again one more time.If you do wouldn't wiping the dalvik & cache after your new Rom is installed erase,remove the new Rom that you just installed.Is it alright to just wipe the partitions except the sd card before installing a sense Rom over a sense Rom or vice-versa going from a sense to a nonsense Rom and or nonsense to a sense Rom. Thanks...

Hi,
If you want a clean install ,then it is correct to wipe all the partitions except the sd card.
A simpler way is to use a SuperWipe zip.
This does it all for you.
You only need to do it once,before installation of the ROM.

When I change Roms, Iwipe cash, then wipe dalvik cash, then I wipe data factory reset, then install zip from SD , reboot, and I'm finished. I don't format all partitions except sd. Maybe I should be doing that. I only wipe BEFORE installation and not after. It's been working for me I've never had a problem yet thank God! Usually I pay attention to what the developer says to do on the Rom site. Each Rom has specific flashing instructions. If the Developer asks to format partitioning of sd card I would do it because every Rom is different.
I just have not came across those instructions yet. I suppose everyone does things a little differently also. This is just the way I do it. Others might do it differently. I have not had any problems yet and I flash a lot! Just follow recommended instructions and you will be fine. Best wishes. Happy flashing !

Check your rom thread before using superwipe as it causes issues with some builds. An alrernative is to wipe user data/factory reset, then wipe both caches using 4ext recovery.

If i do factory reset in setting in custom rom rooted will l i lose root?

if I do factory reset in fryrom for p-5100 which is already rooted will I lose root or brick the tab ?

Nope.

No. You can do it on the stock ROM and keep root too. Just removes user files and settings.

Does it wipe the internal SD card?

I think so... I believe /sdcard is in /data... and a factory reset wipes /data
A stupid way to do it, but yeah...
EDIT: yup, it's /data/media

The i705 has the SD card in /data/media/ also, and wiping data from cwm does not touch the SD.

We're talking about doing it in the phones settings not in a custom recovery.

I believe what the option in settings does is sets a command to /cache/recovery and then boots the phone into recovery where it executes the "wipe data" command. It wouldn't be able to delete everything if it didn't go into recovery as some stuff would be in use.

Oh so MrHyde03 is right and it doesn't wipe the internal SD card?

I remember doing a wipe on my tab before I ever rooted it. Select wipe from the settings menu and it reboots into stock recovery and does a data/cache wipe. It never erased my SD. Not saying his won't, just stating mine didn't.

@SHELDON COOPR This might work.
1. Install latest Android-Andi TWRP recovery.
2. Check the md5 of the ROM and Gapps and copy them to your tablet (if you have a microSD card put them on that instead and insert it into your tablet.
3. Boot into TWRP and make a backup.
4. Click Wipe > Advanced wipe. Select system, data, cache, dalvik. If the ROM and backup are on your external SD card then wipe internal SD also.)
5. Flash ROM.zip and gapps.zip and any other addons.
6. Click "Wipe Cache/Dalvik."
7. After the wipe is completed, click "Back" then "Reboot."
8. Once the ROM reboots to the setup screen, let it sit for 5 minutes and then reboot back into recovery.
9. Click Wipe > Advanced Wipe
10. Select Dalvik Cache and Cache.
11. Click "Home" at the top of the screen and then click Reboot > System.
12. The ROM will go into "Android is Upgrading. Optimizing Apps"
13. Go through setup like normal and enjoy the ROM.

Wow, that could be a problem. I found this article that might work. http://www.digitalreborn.com/fix-samsung-galaxy-unable-mount-efs/
One other thing that I thought of was to Odin back to stock, but that might not work if what I said above didn't. So I would recommend looking at the link above.

Ignore what I just said about re-flashing stock with Odin.
efs is a partition on the phone's internal memory that is used to store important information (like the IMEI - the unique serial number of the phone). It's not accessible to a normal user and shouldn't get corrupted under regular use.*
With all of that said, you're apparently having such a problem, but I'm pretty sure that simply rewriting the firmware isn't going to fix this - that partition isn't included in the stock firmware files.

Quoted from http://forums.androidcentral.com/samsung-galaxy-s3/377195-what-does-failed-mount-efs-mean.
One thing I make sure I always do is make a backup of EFS before I flash anything. (The latest @Android-Andi TWRP will do this)

HI everyone
is there any chance to restore efs to my tablet, which i accidentally deleted while installing new os.....
thanks

You may have installed the wrong rom like P3100 instead of P3110?
Happened to me with my P5113, instead of P5110 , I did P5100.
Was able to go into D/L mode and odin flash correct rom.
