[Q] CWM ROM kernel updating? - Epic 4G General

Apologies if this question is fundamentally stupid, I am a noob and have never tried modifying a ROM.
My question is if I can copy a CWM kernel zip file contents into a CWM ROM zip file and flash my phone without breaking / bricking my phone.
Background Info
I typically try and run the latest leaked stock ROM.
At the moment it is EH17.
I swap out the kernel for the plus kernel so that I can run ext4
I'm looking to start trying out some themes
I recently watched qbking77's video on how to uninstall a theme
Its essentially just just re-flash your CWM ROM
I would like to be able to flash without having to swap file systems every time.
Will extracting the ROM zip, overwriting files with kernel zip contents, rezipping, and flashing my phone cause problems?
Thanks for any help you can offer

Hmm, if you are just running a stock rom, you dont need to uninstall anything. You can just download a EH17 theme (or whatever type of ROM you are on), boot into CWM, wipe cashe and dalvik cashe 3 times each and then choose install from sdcard and choose the theme you want to flash.
Now if you want to try another one after that, do the same process. Wiping the cashes and flashing the theme is all you need to do.

[TUT] Flashing your first A500 custom ROM

Well, flashing a custom ROM on our beloved Iconias became quite easy now thanks to developers on xda. Most of you are quite familiar with the procedure but there are still people that ask basic things all over the ROM developement threads. This is just a beginner's guide, an attempt to collect all the procedures and tools in one thread. Nothing of this is my work and I would like to say THANK YOU to sc2k, thor2002ro, Euclid's Brother, Chainfire, monki-magic, drellisdee, ezterry, Skrilax_CZ, gersma and all A500 developers for making this possible.
You will need the following: external SD card, root rights, unlocked bootloader (if you're on stock ICS), custom recovery and a custom ROM of your choice.
Well lets start by placing an SD card in the SD card expansion slot. Its file system should be FAT32!
*This is optional: To be sure it is recognized later in CWM, format it first with SD Formatter - a tool that can be downloaded from here. Use your home computer / notebook with a card reader for this procedure. Alternatively you can do this using an ANDROID phone.
1.ROOT
Root for Honeycomb 3.0.1 by monki-magic
original thread by Slowie911 here
1. Make sure usb debugging is turned on and unknown sources is selected in Applications settings.
2. Have a micro sd card inserted and turn the tablet on portrait mode and lock it with the switch to fix it in portrait.
3. Download and execute the attached apk. (i had to download from my comp and transfer to the tablet for it to work).
4. Once the apk is installed run the root procedure within the app which was installed
5. Wait and you will receive full root access.
Download Gingerbreak 1.20
Root for Honeycomb 3.1 by sc2k thread here
1. Goto Settings->Applications and enable "Unkown sources"
2. Download the attached APK file
3. Copy the file to your Iconia
4. Install the APK & start the tool
5. Click "root"
6. Enjoy

Download Iconiaroot 1.3
Root for Honeycomb 3.2.x OTA
Unfortunately there's no dedicated rooting app yet developed for HC3.2. It also comes with a new bootloader. In order to get root you need to revert to an older version of Honeycomb first where Iconiaroot works. How to do that is explained in details in this thread
UPDATE: if you're on OTA HC 3.2.x then you can just update to ICS and use the method for rooting ICS - links posted below
Root for ICS 4.x.x OTA

or
Full root for A500 ICS 4.0.3 - Simple method, posted by ZeroNull
2. Bootloader
Since there are many new ICS custom ROMs and custom recoveries, please read in their dedicated threads if they require ICS bootloader. Some of the ROMs can recognize the version of your bootloader and load the proper boot.img during boot. In general - if you're on Honeycomb - you have HC bootloader. If you've updated OTA to ICS, then you have stock ICS bootloader, that is unusable for flashing custom ROMs and therefore you need the unlocked bootloader. A guide on how to install it read here - thanks civato. This thread links to a nice little piece of software (option 1) by gersma that can automatically do all the job for you - install ICS unlocked bootloader and custom recovery. Read and download here - AfterOTA by gersma
3.Custom recovery
original thread with clockworkmod recovery by thor2002ro here
1. Open Market app with your tablet and search for Acer Recovery Installer.
Acer recovery installer
2. Install it and then open it. It has ClockworkMod Recovery by thor2002ro rev1.3.4 built-in.
3. Select "ClockworkMod Recovery rev.1.3.4 by thor2002ro". Tap on install Recovery Image. A popup offering to backup current recovery image will appear. Surely, buckup! Thus you can restore your original recovery image in case of need. Then CWM will be installed. Once it is installed you can remove Acer Recovery Installer tool from your system if you want.
thor2002ro updated CWM to 1.7.3. You can download the zip from tegraowners.com. Later versions of his recovery does not meet GPL because of the "mini" kernel of his - sources not being released. It supports flashing both from internal memory and the external SD card. In order to update your CWM to this latest version, place the downloaded ZIP on your external sd card and update from your CWM by choosing install zip from sd card. Alternatively you can extract the recovery.img from the zip, place it on your external sd card and install it through Acer Recovery Installer by choosing Custom or Stock recovery.img from micro sdcard.
GPL compliant recoveries
RA Revamped for Iconia
TeamWin Recovery Project (twrp) - needs ICS bootloader
A500 Public Recovery
Since the creation of AfterOTA by gersma, you can use his software to install both the bootloader and CWM before flashing the ROM. Get it HERE
4. Flashing custom ROM
Download the ROM of your choice which should be a zip file. Place the zip on your EXTERNAL SD card. Power off your device. Now hold volume down and power buttons together until you see text appearing on the top left corner of the screen - you can release both buttons now. Wait until CWM loads. Volume keys (Up and Down) are used to navigate the CWM menu. Power button is uded as "Enter" i.e. to proceed with your selection. Before going on to install your ROM do a full backup of your system first. Navigate to "backup and restore" and then select Full Backup. Wait untill the operation completes.
Now do the following:
Wipe menu:
- wipe data/factory reset -> navigate to "Yes - delete all user data"
this should format you data partition and cache partition (dalvik cache is gone as well)
Mounts and storage menu
- Format System
this should format your system partition
The above commands are presented in thor's CWM. There are slightly different menus and sub-menus in the other custom recoveries but if you dig a little you'll find that they do the same things and you'll get the idea of what you're doing.
Now you're ready to install your ROM. Get back to the main CWM menu and select
- Install zip from sdcard -> choose zip from sdcard.
Navigate to your zip on the SD card and install it - choose "Yes" again to install. Wait untill installation is complete, return to the main CWM menu and choose "reboot system now".
You're done, enjoy your first custom ROM. Take time for its initial configuration.
5. Flashing custom KERNEL
Flashing custom kernel is as same as custom ROM. You place the zip (Kernels come in zip files as well) on your external SD card and:
- Install zip from sdcard -> choose zip from sdcard.
It is recommended before flashing a new kernel to wipe cache partition and dalvik cache. And of course first you flash the ROM and then the desired Kernel
6. UNBRICKING by flashing a stock ROM
thanks to vache we have full packages shared in his topic
vache said:
Once the desired file downloaded, you have to use Acer Update Decryter by thor2002ro to decrypt them.
After decrypting the file, you have to extract the update.zip from it, put it on an external SDCard (does not work on internal memory) and boot your tablet with Vol- & Power. The update will launch automatically.

This is fantastic. Thank you. I have had my iconia for a month now and been looking at flashing a custom rom but kept backing out. Just a couple of questions for clarification:
(1). Does wiping data erase the internal sd?
(2). If by some stroke of bad luck a flash is unsuccessful and a boot loop or similar occurs, am I right in my understanding that you can just go straight back into recovery and re-flash?
(3). What are the chances of bricking the tablet?
Sorry for noon questions, please just wanna certain because my gf bought me this tablet under the condition I don't do anything risky like on my x10 that I flash almost daily haha

1. No, it doesn't.
2. Yes. You can do that. There's another option in mounts and storage -> format system - that will format even your system partition and leave your device bare with no ROM files on it. That would be a really clean install I guess
EDIT: I just saw that system is formatted during ROM installation. So no need to do that
3. Always read first what option you've selected and be sure you understand what it does. If you have CWM successfully installed, you have a powerfull tool to restore reflash, wipe, format etc. I've flashed my HD2 hundreds of times and now my Iconia is on the run Never ever had a boot failiure.

VERY good information here. Thank you very much for taking the time.
I've flashed ROMS on my last two "chinatabs" but haven't gotten into it with my A500 yet. (To be frank, I'm still thrilled with the prospect of OTA updates from a manufacturer after my last experiences.)
It looks like the process is very similar to my Rena3 tablet.

Thank you, that lays it out all nice and precise for us all. Like strider_mt2k, I have been holdng off on the custom ROMs, because my first tablet was a Gtab, and while it became a pretty awesome tablet, it had to be flashed with a custom ROM to be really usable. The OTA thing was holding me back. But I think that I may try to flash the thing this weekend if I get the chance.
Thanks. Glad it could be of use.
nice tutorial dude! thanks!!
could you please make another tutorial to return back to stock?
specially to return back to stock te kernel.
thanks!!!
As mentioned, best case is if you've backed up your device before flashing any ROM or Kernel. Thus you can restore to your country specific version.
Otherwise its pretty simple - its just like flashing any other ROM following the steps described.

Unfortunately I can not tell you for sure. I haven't tried all of the custom ROMs but in most cases - no you won't be able. I've tried Tabooney, Honeyvillain, Virtuous Picasso, Virtuous Galaxy. ROM developers usually update their ROMs to the latest base available. I think it depends on many things - base, kernel, stock apps removed etc.
Maybe someone who have succeeded with custom ROM updating would share his experience.
Can anyone tell me if there is a version of ROM manager that supports the version of CWM that there is for the Iconia. I would love to be able to simplify my ability to backup my ROM's before flashing.

You can install a clockworkmod for Iconia no matter of the version of ROM manager. But it is much much easier to use Acer Recovery Installer. I recommend you using it instead of playing with recovery img files. It is a one time procedure after all
Anyway - here's what you need to do if you don't want to use Acer recovery installer, or you don't want to use ADB:
http://www.addictivetips.com/mobile/how-to-install-clockworkmod-recovery-3-using-rom-manager/
instead of CWM 3.x you will need to get CWM from thor2002ro In this guide you substitute the recovery that ROM Manager is about to flash with thor's CWM. I haven't tried this method myself but it should work.
With Acer Recovery Installer you can flash custom recovery as well. As long as you have it in IMG format you can be flashed from within the app - "install custom or stock recovery image from sd card".
great thread.
thanks!!!
Great Tutorial!!!
Just a couple of doubts:
First question: Backup files.
3. Flashing custom ROM
"...Before going on to install your ROM do a full backup of your system first. Navigate to "backup and restore" and then select Full Backup. Wait untill the operation completes. "
Where do the backup files go in the system? On internal or external SD card? Is it an *.img file extension?
Should i move it to my computer to keep it save, or just leave it where ever they are?
Second question: Kernel.
4. Flashing custom KERNEL
"Flashing custom kernel is as same as custom ROM. You place the zip (Kernels come in zip files as well) on your external SD card and:
- Install zip from sdcard -> choose zip from sdcard.
It is recommended before flashing a new kernel to wipe cache partition and dalvik cache. And of course first you flash the ROM and then the desired Kernel"
I am on Stock 3.1 ROM with original Kernel, if i want to try Virtuos Picasso, do i have to flash a new Kernel? And if yes, shouldn't i do it before flashing the ROM? Or just flash the ROM and then the Kernel? What happens if i just flash the Rom and use the stock kernel?
Thank you..
Your backup goes to your external SD card in a folder named clockworkmod\backup\2011-XX-XX.HH.MM.SS
As you can guess the name of the backup corresponds to the time it is created. This backup can be used to restore your system through CWM in case of need.
CWM does not backup /data/media folder. Additionally: you should also delete .android_secure.img from your backup set or a full restore will fail before it restores flexrom.
The last is an issue described by Euclid's brother:

No, of course! Your custom ROM (Virtuous Picasso in your example) and any ROM comes with its Kernel. Its up to you to decide wheather to change it or not after that by flashing another Kernel. Follow every Kernel developer's notes for ROM compatibility. So, that answers the last part of your question - you cannot flash Virtuous Picasso and still think you're on stock kernel

Oh, i see...i thought that the flashing ROM procedure of a custom ROM, would just flash the ROM and not the Kernel...so in this case i just have to choose the ROM that i want to flash and do not have to pay attention about the Kernel compatibility...unless i flash a Kernel only. Right?
Thank you very much!!
That is correct

[Q] Superclean MS2

Hello all. Somewhat new to flashing ROM's but not rooting. I'm wanting to flash the SC MS2. I've got a good backup using the CWM without issue. But now kind of looking for straight-forward info on the ROM flash. I've looked at the SC MS2 thread from skynet11 and I'm not sure what Atlas is for so I'm hesitant to move on.
I'd like to think that since I've got my backup of the ROM and data/apps, I can just use three-button on the phone and flash from the SD.
Any suggestions/guidance is appreciated.
Cheers

What rom/kernel are you currently running? That will determine how you proceed with flashing SC MS2.
The Atlas file is for getting your phone back to stock and will come packaged with the stock rom - and you flash stock roms via Odin. Custom roms are flashed via cwm. Place .zip on SD card, boot to recovery, wipe data, cache, and dalvik cache, and flash
Its on EH03 and kernel version is 2.6.35.7
How should I proceed? Wipe and then Flash with cwm? Or do I even need to wipe the data?
Thanks again for your help. Hopefully as I learn more I can contribute back as well.

Once you have CWM properly installed, download the Superclean MS2 .zip file into your SD card. (Make sure the .zip is OK, first).
Then go into CWM and wipe data/factory reset 1st. Then select "install zip from SD card". Then select "choose zip from SD card" and find the file. Select "Yes" to flash. I suggest you also wipe Dalvik Cache by going into the Advanced menu.
After everything is done, reboot, and if you want , you can flash a kernel like KBG.
Enjoy!
Thanks!
Although, What benefits are there to flashing the kernel?
Also, and sorry if I'm being a bother, but I "thought" I did a backup this morning and I'm looking at my SD card in the cwm->backup folder and I don't see the timestamp I thought I'd see from today - there's one there but from 2000-01-01 - is that one it?
Thanks so much!
Once last thing - the gapps.zip - how's that installed? Thanks

It's just flashed the same way as any .zip file, like the SuperClean.
Benefits of using KGB? Many... like being able to overclock and undervolt, back light notifications, and enabling Voodoo lag fix.
I haven't done that many CWM backups, because.. they are not that useful, IMHO. I don't have anything worth backing up in my phone anyway. (All my contacts are in Exchange) and your SD card contents are untouched. Plus, I can get all my apps back from Android Market in no time. If there are some specific apps (and its data) that you want to backup, I would use Titanium backup.
Perfection! Thanks so much!! now on SC without issue. Was a bit concerned when I didn't know how long it would take to wipe the data (seemed forever but in reality only a few mins), but flashed it, then the gapps and have restored the apps I wanted using Titanium. CLEAN!!!!!!!!!!!!!!! Thanks again very much!
Great thread, I am in the same situation: currently on SC3 M1 with KGB kernel and EH03 radio.
I want to flash to SC3 M2, keep the KGB kernel, and possibly try different radio. I just want to make sure I have my steps in the correct order:
1. Download SC3 M2 .zip to SD card
2. Download KGB .zip to SD card
2. Backup apps to SD card (with Ti or Astro)
4. Reboot into CWM recovery (red)
5. Wipe data, cache partition, dalvik cache
6. Disable Voodoo Lagfix and /System lagfix???
7. Install SC3 M2 from ZIP
8. Boot up into SC3 M2
9. Reboot into CWM recovery
10. Wipe cache partition and dalvik cache
11. Install KGB from ZIP
12. Boot into SC3 M2, then reboot back into CWM recovery
13. Enable voodoo lagfix and /system lagfix
14. Reboot
Am I correct about the points where I would disable lagfix?
At what point would I flash a different radio?
Thanks!

clockwork mod recovery question when installing roms

Hey guys, just a quick question, do I have to wipe userdata when installing a new ROM? Should I install a rom and hope it works? And then suffer the consequences? I'm running stock with Trinity kernel, trying to go to latest cm 10 or whatever it is.
Thanks
-Micro
You can get away with over-flashing (or "dirty flashing") very closely related ROMs.
For instance if you were testing CM nightlies from night to night.
In general though it is not a good idea, and even in the case of closely-related ROMs there really are no guarantees. It is certainly not a good idea for a random pairing of before/after ROMs.
BTW the "wipe" that you want is a wipe of /data that clears everything but /data/media (so the "/sdcard" doesn't get nuked), plus a wipe of /cache. In TWRP this is called "factory reset"; I'm not sure what it is called by CWM (note that in the stock recoveries all of /data gets wiped by the "factory reset", so the term means slightly different things in different contexts)
good luck
Hey thanks a lot. Did not know it would't erase the "sdcard" so I installed cwm cm and trinity kernel. Then reinstalled all my apps with titanium. Okay one more question. How exactly do I install cm and trinity kernel? Here's how I did it. I went into ROM manger, downloaded cm, added gapps and then clicked the add zip and selected trinity kernel.. Is this right? Does it matter what order you go in? How would I get rid of trinity kernel? If I were to get rid of trinity kernel, I would have to install a different kernel right? Cm doesn't come with a kernel since its just a ROM right? Also does the cm 10 come with a boot animation? Since I installed trinity second, I have trinity boot animation..
Thanks again!
-Micro
Whew that's a lot of questions - I'll answer a few but not all. (I don't ever use ROM manager.)
By convention, all dev ROMs come with a boot image (which contains a kernel and ram disk), so if you combine an arbitrary ROM and kernel, the kernel needs to be flashed after the ROM.
If you don't like that kernel and want to revert to the one the comes with the ROM, just dirty-flash the ROM again. (This is an example where dirty-flashing should be completely safe - it's the identical ROM! /system won't change even though it is being flashed... unless you customized the ROM since you installed it. FYI some root-aware apps & even TiBu can do this depending how you use it... so dirty-flashing could bust things in that circumstance).
An even safer method would be to get a nandroid backup of the ROM before you flash the kernel mod. TWRP allows you to the option to restore only individual partitions, and this would allow you to restore only the boot partition. I'm not sure if you have this kind of flexibility in CWM or ROM manager.
Backups give you freedom and confidence. Make sure you are making them, and getting copies of them off the tablet, as it is easy to make a mistake and accidentally wipe all of /data including the pseudo-SD card.

urgent! stuck on splash!

hey all,
so i am incredibly new to this scene and just recieved my s4. i was preparing to flash a ROM onto my phone, and got it rooted and installed CWM.
I forgot to download the actual ROM zip file, and went into CWM via goo manager, wiped factory/data and cache. It was only AFTER i wiped everything that i realised i didnt download the ROM zip file, so i rebooted the phone and now it is stuck on the start-up splash screen where it displays "Samsung galaxy S4 GT-I9505" and will not continue :crying:
I was running on stock, and had only rooted the phone.
PLEASE i urgently need to fix this ASAP. Help!
Hi,
is there a Odin Version of the Rom you tried to flash? If yes, you could simply bring your device to download-mode and flash the Rom with Odin.
Alternatively search for a odin flashable Recovery and flash this first. Then you could boot to recovery and flash the zip of the Rom.
Sent from my GT-I9505 using xda app-developers app
i tried installing the liquid smooth rom, and from what i can see there is no odin version of the rom :\
Are you able to direct me to an Odin flashable recovery I can use?
im really stressing out about this
i'm in the process of downloading a stock firmware and will try to flash it on, but it's taking forever to download
I don't see why you can't boot again if you have only wiped the user data and cache, just press the home button for 10 seconds and see if it restarts with your reset stock firmware. Otherwise you can reboot into recovery and do the wipes again (not the option to install a new ROM), or put the ROM zip you want to flash on an SD card and then flash from the SD.
I hope this helps.

hey all,
so i am incredibly new to this scene and just recieved my s4. i was preparing to flash a ROM onto my phone, and got it rooted and installed CWM.
I forgot to download the actual ROM zip file, and went into CWM via goo manager, wiped factory/data and cache. It was only AFTER i wiped everything that i realised i didnt download the ROM zip file, so i rebooted the phone and now it is stuck on the start-up splash screen where it displays "Samsung galaxy S4 GT-I9505" and will not continue :crying:
I was running on stock, and had only rooted the phone.
PLEASE i urgently need to fix this ASAP. Help!

You should of made a backup with CWM. That's what it's used for also, besides flashing .zips. Always make a backup that you can restore and keep an extra copy on ur computer and/or a usb drive.
You have to use Odin to flash a stock firmware from Sammobile website. Make sure you download the correct firmware for your phone.
Dont worry, your phone isn't brick.
when i first did the wipe, i chose the option that i was going to install a new ROM. I'm now assuming that's where i made a mistake.
I did make a backup before i wiped everything onto my SD card, but now i can't even access that backup because it's saying there's nothing.
I've tried flashing a ROM onto it, but it says aborted.
Yes SORF ist right. It should boot into resetted stock firmware.
First try to copy the Rom to SD and then boot to recovery an try flashing it.
If booting to recovery doesn't work (but it should work if you just wiped user data and cache) you should try flashing new recovery with odin.
You could use Philz recovery for GT-I9505 from here http://forum.xda-developers.com/showthread.php?t=2281367
Installation Instructions for installation with odin you find here http://forum.xda-developers.com/showpost.php?p=39433857&postcount=4

Thanks, that's what I'm doing right now, but the file is about 1.8GB and taking so long to download...
i wish there was a faster server, but this is the only option i could find :\
Have you tried to boot into recovery again and then flash your already downloaded rom from sd? So you don't have to download a complete sammy rom.

yes i have tried that, and it says that install aborts.
Also when i re-wipe everything and then try to reboot, it says my device is missing root.
When i try to re-root, and the device reboots, it gets stuck on the intro screen again so the root doesn't actually complete installing
have you fixed it yet?
so im going to try a different ROM other than the liquid smoothe one i wanted (since it keeps saying aborted)
question: does it matter if i use ANY s4 ROM regardless of carrier? I'm from Australia and there is no specific carrier for my phone on xda
Why does it fails to install? Are there any more error messages?
Also you can try the point "Fix Permissions" under Advanced Options. This could help.

try something lite like miui - it will save you time on download and is a good solid base to work from. dont flash the lite gapps without a reboot.
for a solid Sami based rom then i suggest using GoldenEye.

ok so i went ahead and found the cyanogenmod one
http://forum.xda-developers.com/showthread.php?t=2317040
and installed this and it works
though i dont like the look of this ROM lol, i prefer something a little more stock looking.
Any recommendations?
When reflashing a new ROM, what is the process i need to follow?
Cyanogenmod is themeable. So you could search for a stock like theme and install that.
If you like an overall more stock rom try scottyf79's recommendation.
If you want to flash a complete new Rom first copy zip onto sd, then boot into recovery, wipe data and cache, then falsh zip file.
Try the Omega Roms. They are close to stock.
Closest to stock are the prerooted DJembey ROMs (the CWM ones) or the Wanam Lite ROM (it's what I am on now)

personally -
i use Philz recovery
before install of a new rom - i use the "new rom" wipe option rather than the normal data,cache and dalvik wipe (it does this but adds in some extra steps)
then flash the rom of choice
if you get any other messages before reboot - select no
like i said before, if you want a stock looking Sami rom then try Golden Eye.

Procedure to go back to MIUI from CM13

Hi. I'm using the 18/Redmi2Prime and I was thinking of reverting back to MIUI and I'm on CM13. I'm kind of confused with all the threads here because it's been a while since I was active here in the forums. Can't I just flash the MIUI ROM over CM13 using TWRP 2.8.7 with a clean install?
I wanted a rooted lollipop miui hence I am reluctant of choosing this. And I donno which ROM to choose either. Any help would be greatly appreciated!
Grab a copy of the stock recovery from here, and follow the instructions to install it onto your device. Basically, download the file, extract the .img file from it, and install the .img file using TWRP. Then boot to recovery.
Then, download a copy of the official MIUI ROM (beta, release or otherwise), from here, rename it as update.zip, copy paste it to your SD card (internal/external), and from the stock recovery, wipe all existing data (cache and user data - SD card can stay). Install the update.zip from the recovery from the options shown.
Done.
Additional notes -
1. If you are plan to go back to a custom ROM, then install a pre-lollipop based MIUI ROM, or backup your EFS, Modem, Boot partitions prior to wiping the existing recovery - this will save you a lot of trouble, and perhaps opening another thread.
2. It is preferable to download the MIUI ROM and rename it as update.zip before you restore to stock recovery, should anything go wrong down the lane. (That is, without a ROM installed, and the computer just not willing to recognize your device, you might end up in a small soup - you cannot access the files on the phone using the stock recovery easily.)
3. If anything goes wrong, check for instructions on how to install the MIUI ROM using fastboot.
Hey thanks for the quick reply. Will do the mentioned and will get back to you if need be. Thanks again!
But wait. It isn't prerooted right?
