Your record shows" Posts: 138 and Join Date: Feb 2010". So you should have some experience. But you are sounding so afraid that I wonder.

Most of us here take risk, you know thinks can go wrong. The important is to try to be prepare, Read, read and read. Then make sure you have the appropriate tools and files to recover in case of trouble. Understand that if something goes wrong you and only you is responsible. Do not blame anyone else. At this point you should had check what firmware is your device, and had downloaded you OWN particular 4.2.2 Stock Recovery from Samsung. Do you have?

Please tell us the the firmware version of you device. Just to at least force you to look at it. jijij

Most important, Are you in original 4.2.2? For me this is important. I personally do not trust 4.4.2.

Please tell us that you have ODIN 3.07 and that you have downloaded your correct stock rom from samsung.

Please tell me that at this point you had backup all essential information from your P5220.

Please tell me you have an External Sdcard with at least 4g for ease zip installations.

I am an unemployed user. I have some technical background. I have a GT-P5210 -Tab3 10 wifi.

I like to help people but please understand I am no expert. I do know that I learn a lot while helping others.

moonbutt74

There a bunch of good I mean good developers here that I bet you are double as smart as moonbutt74. jijiji I am kidding I do not know.

But what I know is that moonbutt74 will take a problem by himself and spent hours, days,weeks.. until hi find the solution. I admire him.

I do not know why any of the developers had comment yet, I can assume that the lack of FEEDBACK from P5220 owners reporting the result make us be in safe mode. But believe they are out there watching us. jijiji

You know moonbutt74 had read this, look at the thanks. He has been around. But please understand that he has not commit to create for you a new recovery!! I have faith that he will help P5220 in the near future. But when I do not know. So if you what to wait, that is smart. I just do not know when it will happen.

Listen this is what I am going to do. I am going to test the P5220 4G Stock Recovery I downloaded in my P5210 wifi. I see how it behaves. This is not a fill probe that it can work, but at least we can see if the TAB bootloop failing!

As for procedures.

Remember I am no expert!!! If you want to follow me is at you own risk.

Please understand the difference in installing a Custom recovery.img (TWRP) vs root process.

*Just installing Custom recovery.img (TWRP).

First booting in recovery do not affect normal boot process(Android). Is like a X-ray, you can inspect and take x-rays ( backups) without injury Android OS. You cam always replace the original recovery.img and no harm done.

** rooting - Is like an organ replacement operation at the table, you are installing new software that Android could reject and bootloop!!

A) So first step:

Download and have ready all tools and files. No harm done to the TAB3.

B)Watch this video: it is for TAB3 7" but give you an Idea of the procedure you need to follow:

[RECOVERY][TWRP_2.7] SGT3 Recovery[FINAL]=>http://xdaforums.com/showthread.php?t=2442915

1) Once you download file you received:

recovery.tar.zip

2) Unzip you will see:

recovery.tar.md5.tar

this is the file will be using with Odin.

If you let the TAB to reboot automatically after you install recovery with Odin, chances are that su or recovery will fail. So I suggest you deselect "Auto Reboot" only let "F.Reset Time" This is not a tutorial in ODIN I suggest anyone read more about it. In particular DO NOT mark "RE-Partition" it is very dangerous. That is there for very Special occasions.

Odin

1) Turn Off your TAB.

2) Run Odin 3.07

3) Hook the cable to the TAB3

4) Press Just [Power]+[Volume Down] this is enogth in my tab. But if you Prefer [Power]+[Volume Down]+[Menu] Your Tab should Show the Warning! Screen and the Yellow Triangle. Nothing should be shown in Odin yet.

5) As the test read [Volume Up] to Continue. Your Tab3 shows now the Android and read Downloading. Your PC did a "Beep" acknowledging the Driver is ready. Odin now shows in First Slot of "ID:COM" a Blue data that Reads "0:[COMx]" where x is a number for comport. Number does not mater. This tell you ODIN as recognized your Device.

6) Options: Now make sure check-mark ONLY for "F.Reset Time" is selected. Nothing more. Please read my warning before.

7) Files [Download] select check mark of PDA

8) Press PDA and Navigate to where you have your recovery in you case "recovery.tar.md5.tar"

9) "Message" window . Odin tell you the status in this window. you should see

<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..

So be smart wait!!

10) Then is file is validated you will see

<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> recovery.tar.md5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS.

11) Now after you see Successful Odin is ready. If you do not see there is something wrong.

12) Now we can press "START"

13) You should see ID:COM with progress bar. TAB3 shows a progress bar too. On top it reads "Recovery". With time you should read in Message

<ID:0/011> Odin v.3 engine (ID:11)..
<ID:0/011> File analysis..
<ID:0/011> SetupConnection..
<ID:0/011> Initialzation..
<ID:0/011> Get PIT for mapping..
<ID:0/011> Firmware update start..
<ID:0/011> recovery.img
<ID:0/011> NAND Write Start!!
<ID:0/011> RQT_CLOSE !!
<ID:0/011> RES OK !!

14)You need to wait until Blue "Recovery" change to "Reset". Remember TAB3 will not boot automatically since we deselect. So Once we see reset we know it is ready.

15) Now we go to the TAB3 and press [Power]+[Volume UP] to get into recovery. This is important since some time recovery fails if we let the TAB3 reboot in to OS.

16) navigate if you like to see your new recovery

Now do not install root yet. Just use TWRP to backup to External SDCARD. yes external so that if something fails you still have recovery files in your External SDCARD.

So once you have done this report to us.

Good luck.
