[Galaxy Tab 3 10.1 Android Development] dale_para_bajo:
I am new to TWRP and infarct I even got scare my self once by deleting the system partition. I did not new how to navigate to get to my External SDcard. Things that we learn.

In the CWM tread a friend ask how to do exactly the same in CWM. But since I am not using CWM any more I will post the answer here with TWRP solution. I hope you forgive me.

I used CWM to root my device first time. It work perfect. But I could not obtain a full backup so I stop using it. And I start using TWRP. TWRP response very slow some time you have to wait 3 seconds after you press a button. And it tend to bring you to Home Screen when you are trying to press buttons!

You can easily change the recovery with ODIN. So moving from CWM to TWRP or the other way is easily done even if you have problems with the rest. I my self lock me out when I deleted the system with TWRP so the P5210 did not boot.

If you decide to use TWRP remember to place the P5210 on a Flat surface not on your hands. With at least 50% Charge. TWRP is Laggy! So use only one finger and carefully press Firmly for your selection. Then wait for the tablet to respond. Most of the time you have to wait 3 seconds. Do not Press twice, wait. Clearly is it pass let say about 10 seconds you can try again. If you are slow the from time to time a Lock image Pops up and you have to Firmly Press in the Blue AREA and Slide you finger on a moderate speed.

Enabling External SDCARD

*Using TWRP I enable the reading of the SDCARD (external SDCARD). To do this PRESS [Mount] in the Home Screen. In my case <cache> and <Data> partitions where already selected. To Enable "External SDCARD" I selected <Micro SDcard>. Then hit BACK Button in the White Border Area of the P5210.

But the first time I found my self unable to select the zip file from the external SDCARD to Install! What I did was Copy the File from the External SCARD to the INTERNAL so that I could install the zip. But this should not be required. I guess you could boot again in recovery to see if it get mounted. Please see at the end How to copy a file from external to internal if you need it.

Installing ZIP from external Sdcard

* Now Press [Install]

A windows Pop up withe a message "Select Zip to Install" You should be at "\emmc" directory. But if you need to used the zip in the external navigate to "\sdcard". yes in my case Internal is mounted at "\emmc" and external Sdcard is at "\sdcard".

*So Press <(Up A Level)>

*Use 1 finger to swipe in the Up direction in the Folder area to be able to rool up and look at the area where the "\sdcard is located"

*Press <\sdcard>

In the right side are the files so select the zip you need to install

* Press over the zip File in my case "BinDroid_ONE_P5210_V3.0.0.zip".

A new windows pop with message "Warning this Operation may install ..."

You should select the "zip signature verification" ( Clearly is your file is not signed then you do not used it)

* Press firmly in the Blue area and "Swipe to Confirm"

There are other options to cancel or add more zip. Amusing you confirm then you need to wait. Do Not Touch your screen until it finished. And when Reboot let the device initialized. Until it requires input from you.

Copy Method

*To Copy the ZIP I Press: [Advance]+[ File Manager]

Then Navigate to "\sdcard" this the directory that TWRP is mounting my External SDCARD! I know confusing no! Why it does not use "\extSdcard" I do not know! But maybe that is where you have to look in CWM.

I then copy the ZIP, in my case I used "BinDroid_ONE_P5210_V3.0.0.zip". But I guess you could use "GRIEVOUS STOCK.zip". You can find it in his thread http://xdaforums.com/showpost.php?p=48956466&postcount=42 But I have not use that one my self yet!

*To copy the file from the external to the internal while in the "\scdacrd" select the zip file ( I selected BinDroid_ONE_P5210_V3.0.0.zip) by presing over the file <BinDroid_ONE_P5210_V3.0.0.zip> on the right side where the files are. Left are for folders.

A Window Pop up with header "File Selected /sdcard/BinDroid_ONE_P5210_V3.0.0.zip"

*I Press [Copy File].

A Window Pop up with Header "Browse to destination Folder & Press Select"

* So I Press "<Up A Level>"

* Then Select </emmc> folder, again I know weird no! But that is what I use. Please verify that that is where your "Internal SDCARD" is mounted.

* While inside "/emmc" PRESS [Select Folder]

A Windo Pop Up "Copying /sdcard/BinDroid_ONE_P5210_V3.0.0.zip to /emmc" "Press back to cancel"

*To execute Press Firmly in the Blue and "Swipe to Confirm"

A new window "Copying" "Updating partition details"

If everything goes right you will see "File Operation complete Successful".

*Press [Back]

You can then navigate to select another file. In my case I navigate again to "\emmc" to double check that the BinDroid_ONE_P5210_V3.0.0.zip was copied.

Now we can install the zip

*Press Back button in the white area(Border of P5210) near the Home to go to Home. We are in the Advance menu. Press again to go to home.

I guess the Back Icon is in the Top Window too! And there is a Home Icon too!. But There is a Square icon with dots that when press the screen kind of freezes! I am no TWRP user I guess that is for system messages, I have move out by pressing that button again. But Since I am not sure I try to be away of it.

* Now I can use the Install. PRESS [Install] Explain before
