Hi ZhenMing, I tried this, the usb drive could recognize my p6800 but when I tried to ADB devices, that could not list anything, while KIES is not able to connect to my phone while during the download mode either.
Here is the result i got from ODIN:
<ID:0/004> Odin v.3 engine (ID:4)..
<ID:0/004> File analysis..
<ID:0/004> SetupConnection..
<ID:0/004> Can't open the serial(COM) port.
Please help :crying:

Galaxy Fit GT-S5670 - MIBIB Download & SETUP CONNECTION

This thread is for those friends who are new to android.
I found that many of us, who wants to move from custom roms to stock roms through odin, have faced some big problems like MIBIB download or SETUP CONNECTION . This happened with me as well... when I moved from cyanogenmod to froyo. So, based on my experience, here are some suggestions which may help you:-
When you select the OPS file, check its name. Its name should be "BENI_v1.0.ops" (without quotes) otherwise odin will not show your device's model number at the top and will stop at MIBIB Download. Please Note that as soon as you select the ops file, odin will show the model number of the device in its title bar regardless of whether the phone is physcally connected to PC or not. In my case, the mbib download problem is solved by renaming the OPS file. You can now install the stock firmware as normal.
If odin is showing the message "setup connection" and your Galaxy Fit is still connected to PC (i.e. COM port mapping box is yellow), then try another stock firmware. In my case, odin stopped at setup connection when I was installing froyo, so then I tried the One Package Gingerbread firmware. And Odin successfully installed it(you can also try another usb port). After then, I went for Froyo once again & Odin successfully installed it too.
Please remember that doing things unknowingly may damage your device. Once the phone is in DOWNLOAD MODE, it can not be switched on either normally or in recovery. It can only enter in DOWNLOAD MODE. I had the two firmwares when I did all this.
Hope this helps...
Press thanks if I helped you...

U saved my day ....

Note that if ur usb port malfunctions then odin will not proceed further. I recently noticed this major issue. Other errors like "checking plact platform verification" appear due to usb error. Try another pc or laptop(recommended).
1st & 4most, it's necessary that u tick "USB debugging" under "Android Settings->Application Development" b4 going to download mode.
Also, disable any antivirus, firewall...uninstall kies...& at last install/re-install ur Samsung Mobile Drivers. Use Odin 4.38.
The screen u mentioned appears when u exit download mode & try to switch it on either normally or in recovery. Don't worry...!!
1. Take out & re-insert battery.
2. Press "Volume Down & Home & Power button" & you'll again enter downloading mode.
If u want...I can provide u the firmware files that I always use
Hope this helps...!!!

Screwed something up, HELP needed please

Howdy,
I've screwed up with installing a custom rom over another custom.
Now I'm getting an error:
Firmware upgrade encountered an issue. Please select recovery mode in kies & try again.
It's a tablet:
Samsung Galaxy Tab 2 10.1 (p5100)
In my computer im using windows 10 pro, and adb device is not regonized.
What I neeed to do to get pasted that error?
Thanks for the help!

There is nothing to worry.
It is easy to solve this.
Just download Odin in your pc.
Download the official firmware if your device here.
http://www.sammobile.com/firmwares/database/GT-P5100/
Now open Odin In pc
Connect your device to the pc .
Now in the app under PDA browse for the firmware you have downloaded and click start.
Wait till it says pass.
That's it you have successfully solved your problem.
Now it will take some time to boot.
In case you feel that you are in a bootloop just go to recovery and perform a factory reset .
Odin download http://odindownload.com/download/Odin3_v3.10.6.zip

Greetings;
I don't know if you already entered Download Mode...
Most problems accessing Recovery and Download Modes are due to having the USB Cable connected.
Remove the cable; press the key combination; and it will boot.
(Except if there's some incompatible ROM flashed by mistake).
After that plug the USB Cable again (if your USB Drivers have also installed for Download Mode) Odin will recognize it (like shown in your Screen Shot).
REMEMBER:
While Flashing do NOT Remove USB Cable, untill Odin Displays "Pass" message.
Further issues: Let us know. We're would be Glad to help.

Is it fixable? Bricked S6 won't boot or accept ROM flashes.

Previously, I've talked about how I bricked my G920T by using an apk to try to root my phone.
Then I tried to do a factory reset with the stock recovery but it wouldn't even go into the stock recovery. So I flashed TWRP and wiped the whole phone including the system partition.
Then I tried to flash a stock 6.0.1 firmware to the phone but doing so did not improve the situation as my phone still won't boot. Even worse, when I power my phone, all I see is the blue LED indicator, no Samsung logo, nothing.
Then I tried to flash a custom ROM like XtreStoLite but that didn't fix anything either.
When I use TWRP or the stock recovery, the error "failed to mount /efs (invalid argument)" comes up on the log. I tried using the ADB method to fix it but my phone would not get recognized by ADB probably because USB debugging isn't on by default.
I cannot shut down the phone without having it charged to a power source then holding down PWR+DOWN VOLUME+HOME until the screen shuts off.
When I enter download mode, I don't see the warning screen, I enter the download mode directly.

It will warm you when you enter download. Or use TWRP and reboot into Download.Once in download flash the ROM using Odin. Get the latest one from SamFirm.
P.S. Next time root using CF Auto Root

It doesn't warn me when I enter download mode, that's one of the problems.
I tried flashing the official ROM using ODIN, it still won't boot because of the efs error.

1) Download the latest SmartSwitch
2) Click on more -> Emergency software recovery and initialization
3) Go into Device initialization, enter your model name, search for it and proceed as advised by the assistant
That should fix everything, otherwise:
1) Download the latest official firmware for your model, the 4-File (or 3-File) Version
2) Use latest ODIN, check repartition in options
3) Select all the files and flash it

If EFS or DRK is corrupted, flashing roms, custom or not won`t help, it can be fixed via repair box maybe (Octoplus/Z3X)
Try to flash CF auto root for your model, if it still won`t boot, then find someone with a box to try to help you remotely or not.
But Smart Switch emergency initialization with phone sn would be the first thing I would try.

Which mode should I be in when using SmartSwitch? No devices are shown when I have it plugged in during the bootup, and is so too in download mode but shows a not supported message.

Well if you know someone who have a box, it doesn`t have to be remotely.
If not, it is possible to fix it remotely, with help of usb hub (FlexiHub or similar), tunneling (TeamViewer or similar) and box software (you connect phone to your computer, the other guy connects box to his computer, both of you are connected through a gateway to a wonderfull thing called internet, and everybody is happy ) .
Same as on site, just with few more things in between the phone, and the box.

The S/N sticker on the back of the phone is long gone, is there any other way I can find it besides from going into settings because I can't do that?
EDIT: I am able to borrow a friend's serial and got the firmware installed.
The Samsung boot logo is back now, however, the device still won't boot. The efs error is still there but the download mode warning sign came back.
EDIT #2: Okay, I flashed TWRP now and ADB is working once again. Can I utilize this to fix the efs error?

Galaxy Tab 2 GT-P5110 Restarting and does not install stock or any other rom.

Hi guys, after many tries, many googling and youtube research, I dicided to share my problem with our community
1. At sunday, my galaxy tab started to restart continuously, It was recharging and I took some time to see.
2. I tried to activate USB DEBUGGING but when It Restarts, it's usb debugging is disabled again.
3. I'm using Stock Rom Again...was;
4.Using Stock Recovery.
5. Tried to install many others recovery's with odin and it seems to be ok but after a restart, its all back to stock recover.
6. Tried to install Stock FW again by Odin and its stuck about 50% FAIL
7. Tried to install CFW and Other Roms by SD Card but it shows a messege "Failed to check Signature" aborting... maybe because of stock recover.
8. Not rooted, usb debugging DISABLE
9 Tried to activate USB Debugging by odin, installing a patch, without success.
10 Samsung KIES does not recognize it in Download Mode.
11. I have samsung drivers installed.
one more information, when I start in recovery Mode, it shows first an android pic and a messege NO COMMAND, then proceeds to RECOVERY(STOCK).
What Can I do?? I Did Everything I can find on Internet. Is there a phisical problem??
Best Regards!!

Seems like a similar issue like mine. Check my post about behavior of my tab 2 7" (P3100) at https://forum.xda-developers.com/galaxy-tab-2/help/p3100-16gb-bricked-emmc-bug-to-t3707134
If you have symptoms similar to mine or any mentioned in the links in the post, then it seems you have a faulty emmc (internal memory).
The only solution i get to hear up till now is either to get motherboard replaced from service center or get emmc replaced from repair shop or get it jtag'ed.
Other solutions, which would avoid jtag or other service, like dual booting from SD card existed here in xda for p3100 but having stuck in stock recovery brought limitations.
If possible share all things you tried and solution if you found any.

Tks for the answer, I guess we have the same problem, by the way, I already read your topic (lol), Surelly I'm gonna find some technical assistance , the hard thing is to find these kind of stuff, but let's see. I'm gonna share any solution, see ya!

If you install a custom recovery and then reboot to system, it will automatically install the stock recovery again unless you are rooted. To avoid this uncheck the "reboot system when finished" box in odin and after installing the recovery boot directly into it.
Stock recovery is only for installing official updates, not for custom roms. You need a custom recovery for that.

Thanks, but we I tried this too. The issue is possibly our emmc is gone into permanant write protection state as far as i have studied. i tried unchecking the "reboot system when finished" box and even pulling battery after getting odin status as success for recovery as suggested in some threads but nothing helped.
Even if i do a factory reset from recovery all data would remain as is, nothing deleted!
@blankfile99 i agree its hard to find stuff, for me jtag service is more than 500kms from my place!
I am searching for any possibility to boot from external sd card. The thing existed for p3100 (one mentioned here https://forum.xda-developers.com/showthread.php?t=1866675 which allows sd boot) and the other is the blackhawk NEXT https://forum.xda-developers.com/showthread.php?t=2285366 but this is not suitable for our case where no modifications in emmc contents are possible. Devs were able to carry out sd boot for nook color tab .
But again I am stuck trying the dual boot mentioned above at how to flash the sd boot build rom zip file to sd card since stock recovery gives signature verification failure....
Great struggle to keep the tab working...

I had the same issue - here is what I did (I'm writing this as much for me later on, as for you!). This should be fine for your device - but of course, the usual "no guarantees" applies.....
I assume you have downloaded the appropriate files ?
- I used philz_touch_6.57.8-p5100.tar.md5 (google it)
- Odin3 v1.85
1) Install / Start Odin on computer
2) Start device in download mode For my P5100 - I held down power and the UP volume button.
3) Connect USB cable to computer. In ODIN, Click PDA and select the downloaded philz_touch_6.57.8-p5100.tar.md5 (or whatever you're going to use).
4) in ODIN - UNTICK "Auto- Reboot" and Re-Partition is unticked - leave Reset Time ticked.
5) Click start. you should get the "PASS" All threads completed.
6) Disconnect USB cable
7) - important bit - Press and hold down POWER and Volume DOWN together at same time for about 15 seconds. This hopefully will restart into PhilZ mod.
Let me know how it goes.

I have decided to install custom rom on my Samsung tab 2. but it's not connecting with my laptop(not recognized).I think there's a driver problem because in device manager It is showing "Unknown USB DEVICE". Can anyone please send me the Samsung tab 2 gt p5110 driver software or any folders which are use to connect. (I have tried many times but I can't find a good solution )

@Sura 102005
Have you tried reading and following this - also read the older threads
You may need to install Samsung kies
You should also try with a newer / different cable as that could be the issue. I had this same problem and when I swapped to newer cable it solved the issue. Just try different things.

Hi clappertrap, Thank you for your kindness. I have tried Samsung Kies but I haven't tried a different cable I have order for OTG cable and USB male-male cable. I think this will work.
