[Help] Galaxy Tab 2 P3100 randonly rebooting. Can't flash roms or factory reset. - General Questions and Answers

Hi,
I'm having hard times trying to fix my tablet. Here are the specs:
Model: GT-P3100
Android: 4.2.2
Kernel: 3.0.31-CM
Cyanogenmod v.: 10.1.2-p3100
Recovery: 6.0.1.0
OEM Data Cable
The problem is: The tablet is randomly restarting. So I've tried to flash some roms (Cyanogen12, 13, STOCK Rom) via External SD Card. None of them worked. (Installation aborted, no error messages). Whenever I uninstall any app using the Android App Manager, it uninstalls but then installs again after a few seconds. I already did factory reset, wipe cache, dalvik, .. and even wipe /system, /sd, .. partition didn't work. It always boots on Cyanogen with the same apps installed. Inside the '0' folder there are other folders just like an infinite loop(the same folders I have in the root folder, I have inside the '0' folder, and inside that folder, another '0' folder containing the same files.
Then I did install TWRP using Odin, the device was recognized and the PASS message appeared sucessfully. After the reboot, CWM was still installed and I couldn't load the TWRP Recovery.
Whenever I try to use Kies, a connecting message appears but never ends.
Can anybody help?

my beloved friend,
in odin options remove the Auto reboot option
then flash the twrp
( the device wont reboot)
when it goes PASS

Still got CWM installed...
It seems my SD is somehow write-protected. I've tried to do a "NAND erase all" but it fails after the "erase..." message.
When I connect the tablet to my Notebook, I can delete/write files. in the Internal Storage. Very weird

I've done the following steps:
1 - Turned the Tablet On in Download Mode.
2 - Unticked Auto Reboot.
3 - Selected the TWRP file in "AP".
4 - Plugged the USB Cable.
5 - Clicked on Start.
6 - Waited for the "Pass" message.
7 - Unplugged the USB Cable.
8 - Removed the battery plug.
9 - Waited 10 seconds and plugged in again.
10 - Restarted in Recovery mode.
But I still got the CWM installed.
The pictures of the procedures that I did are attached.

Yes, I'm rooted. Sadly, the tablet reboots whenever I try to install an Application (Via Playstore or Apk).
I already did try installing TWRP using ADB Shell(direcly inside the mmc block) but CWM keeps being the recovery.
Trying to do a Nand erase, I've got an error, as you can see in the attachment.

Mate, pit may kill your device or mess up the phone it it was lucky to boot.
To let you know, nand erase will require you to load the firmware
Please don't do an erase, lucky that your phone booted, please uncheck repartition
And band erase
You said you are having problem installing apps,
When did this happen?
After flashing pit?

No, it was included in the initial problem(random reboots), that's why I'm trying to recovery the Tab. This is my uncle's tablet, he said he didn't do anything unusual lately. The cyanogen mod was installed by a technician, a long time ago.

I'm 99% sure it's EMMC problem related, as -Hope- told me via Discord.
For more information, see: https://forum.xda-developers.com/galaxy-tab-2/general/discussion-alternative-tab-2-emmc-bug-t3306862
I would like to thanks -Hope- for all the efforts trying to revive my Tablet . I said before and I'll say again, you are a GREAT person!! Really thanks buddy!

[ODIN][UCKD5] Odin - Stock (100% or Root+3e) - (Update 06/05/11)

This will flash the stock kernel, modem, system, dbdata and cache. There's no need for a pit since we do not have any other OS versions to flash yet that would re-partition your device.
Instructions:
1) Make sure the drivers for the Infuse 4G are installed.
2) Please unzip the .zip file.
3) Run Odin3 v1.81.exe (as administrator if you are on Windows 7)
4) Place your phone into download mode (pull battery, press and hold both Volume keys, put battery in and plug the USB cable in)
5) Make sure your phone shows up in Odin as COM##
5) Click the PDA button and choose the .tar.md5 file in the .zip.
6) Press Start.
7) After it completes, it will reboot your device and should boot up like normal. If it fails on flash see FAQ Question 4 below!
There is ALWAYS risk when flashing your device. Unfortunately, I will not be held responsible. Please use this as a means to get back to stock if something happens.
* DO NOT FLASH PIT (PIT not included).
* DO NOT CHECK ANYTHING IN ODIN EXCEPT "AUTO-REBOOT" AND "F. RESET TIME" (should be checked by default)
FAQ:
Question 1: Why does it have .md5 at the end?
Answer: Its in md5 format so in case your download is corrupted, you dont brick your phone.
Question 2: Can I rename it to just .tar and flash?
Answer: DO NOT rename it from md5 format. If it says the md5 sum is invalid, then it will not flash. Just re-download again and try again.
Question 3: Why does it give an error if i try to open in in 7zip/WinRAR/WinZip?
Answer: It should! Windows doesn't recognize when an md5sum is written to the end of a file. Don't panic!
Question 4: It passed the md5sum check, but failed writing on factoryfs. What do I do?!?
Answer: This is exactly what happened to me. Don't panic. Follow these steps exactly:
* Hold the power button to turn off.
* Make sure Odin is still open.
* Plug the USB cable in and hold the volume keys down at the same time. You will be on the screen with a "Phone ! PC" screen.
* Press Start on Odin.
* Once it completes, it will boot up into recovery. Don't worry about wiping cache or user data. Just choose "Reboot Device".
This flash takes quite a long period of time due to the size of the files. I'd say it took me 5 - 10 minutes for the flash to complete. Be patient! Afterwards it booted up with recovery, and chose Reboot Now.
Thanks:
* codeworkx - for the advice and assistance!
* beatblaster - First tester after a bad framework-res update.
* Realityfalse - Second tester
* dotsad - Third tester
* imnuts - Very Helpful advice and instructions for Odin installations!

Can you wipe all user data and wipe cache from recovery (power phone off via power button or battery pull, hold both volune keys down, then hold power down until samsung appears on the screen and let go of ONLY power)? That should get you to boot.
This happened to beatblaster when we tested. Then he did the data wipes in recovery and booted up fine.
cant get recovery at all. tried all above. pit doesnt work
Thanks
Thanks for doing this, I am trying to learn how to dev on android and Ubuntu and was installing and also waiting for a way back before doing anything.

Was your phone bricked before trying this? If so, how did you brick it?
Sent from my SAMSUNG-SGH-I997 using XDA App
wasnt bricked. wanted to try odin restore.
how can I clear data and cache without recovery? is there a way in ODIN?

TO get into recovery to wipe data and cache, unplug your phone from the USB cable then make sure the phone is powered off. While the device is powered off press and hold the 2 volume buttons then while holding those 2 volume buttons down press and hold the power button. That will get you into recovery. WHile in there, you can wipe user data and wipe cache. Give that a go.
understood. However, as I was able to successfuly get into recovery by that method before attempting the ODIN restore, It will not enter recovery after ODIN flashed the stock.

Whoa. The only thing I can recommend from here is to try to flash via ODIN again or take the brick back to the store and swap for new. Next time, I'd recommend not fixing anything unless it's broken

Is there any good reason to convert these apps to system?????????????????????????????
Factory reset will reset DATA (user apps) but not SYSTEM. The only way is to install TWRP, delete the converted apps via TWRP recovery file manager OR flashing a full stock firmware via ODIN.

Flash TWRP via ODIN. Start TWRP and select "advanced" --> "file manager" . Navigate to your system apps folder and delete the converted apps. Then perform a factory reset again
Here are the firmware files for your phone. Official release is Android 4.0.4. Just flash the downloaded file via ODIN. You need to pick the right "region" for your phone.

after installing via Odin, TWRP doesn't start !!

YU Yureka with no OS stuck on a Bootloop and unable to enter recovery mode.

Hey guys!
So, i was trying to install CM13 unofficial version, and wiped the system and internal storage using TWRP recovery. I was supposed to install the rom from a zip file i had placed in the external memory card. What i did, was, i rebooted the phone by mistake, after wiping it from the recovery without installing the ROM and now the phone is caught in a bootloop. I know i am an idiot to do that. I tried removing the battery and reboot it in recovery mode using the key combination with no luck. It just starts the boot loop. I tried using fastboot and adb from pc to push files into the internal memory, but my device is not getting detected on the adb anymore (maybe the usb debugging is disabled now?).
What i guess is stopping TWRP recovery from showing up is the lack of twrp/themes folder in the internal memory since i wiped it. But there might be some other cause that i am unaware of. What do i do now? Any help will be greatly appreciated!
Hey! I'm having the same problem with my yu yureka.. Can anyone help me please!

Hi! I'm having the same problem with this post... Does anyone knows the solution of this problem. I'd be really glad if anyone could help me with this..please!
Hey are you able to boot into fastboot mode? If you can....
Prerequisites –
1. Make sure that you have 70-80% battery on your phone.
2. You need a PC and a USB cable to connect your phone to the PC.
3. Flashing the factory firmware will wipe all the data present in the internal memory. So, make a backup of that if you can.
4.Install all the necessary Device drivers.
DOWNLOADS -
1. Download the flash tools from here . http://www.mediafire.com/download/87gfz7mdch188an/Flashtools_For_Yu_Yureka.zip
2. Download the factory firmware from Here (cm 12.1) . http://builds.cyngn.com/factory/tomato/cm-12.1-YOG4PAS3JM-tomato-signed-fastboot.zip
Steps To Flash Factory Firmware –
1. Extract the flashtools zip in a new folder on the desktop.
2. Extract the factory firmware zip in the same folder and make sure that all of the flashtools files are also present.
3. Now, power off your phone. If you are stuck in a bootloop, then pull out the battery and reinsert it. (Do not switch on the phone.)
4. While pressing the Volume Up key, connect your phone to the PC with the help of a USB cable.
5. You should now see the fastboot logo on your device. If you did, leave the Volume Up key. (If you do not see the logo, retry the process.)
6. Now go to the folder where you extracted the flash tools and factory firmware and run the flash-all.bat by double clicking on it.
7. A command window will open and the flashing procedure will start. (Make sure that your device does not disconnect from your PC during the procedure.)
8. The command window will automatically close once the procedure is completed.
9. Disconnect your device and boot it up by pressing the Power button. (Since this is first boot after flashing the firmware, it may take upto 5 minutes.)
Done you should be back on cm 12.1

Sorry to hear that anyway,
By stock lolipop you mean you had the yureka plus with Volte From factory right!!...if so the twrp might have been for the yureka plus with the cm bootloader which got replaced in the new Devcice
I am facing the same problem and in my case I dont think its an battery issue...I was happily using the CM 13.0 Snapshot Rom since a long time...but today morning when I did a soft reset by going into the settings in my yureka...the phone has gone in bootloop...and nothing is working...using fastboot I even flashed the twrp again and also flashed the CM 12.0 Stock firmware..but nothing is working...after the YU logo it restarts....please help...
I am also facing problem maybe worst
I dont know what wrong I am doing but I am getting "FAILED (remote: unknown command)".
Few info:
1. I get my device ID when I do "fastboot devices" but nothing on fastboot -i 0x1ebf oem device-info".
2. Also for my YU5510A fastboot screen doesnt say' "fastboot" it says "Information do not unplug the cable - Secure Phone".
3. I have red light on, phones keeps rebooting 4-5 times than red light goes off and charging stops.

Ignore that and use other fastboot commands and go ahead, as your device is being detected in fastboot mode.

But when I am executing other fastboot commands it halts the process between with error "FAILED (remote: unknown command)".
I have read about this error and people suggested that I need to get into "Download mode" not "fastboot/bootload". To get into "download" mode I tried pressing "VoulumeDown+Power+Home", but nothing happened, it simply restarted the phone.
Please advise.

ROOT J2 PRIME (SM-G532 F/M/G) SUPEREASY 5 steps

now i was looking for how to root my j2 prime because its what i use to login with my vpn then i use a proxy server on it to route all traffic connected to it while its in hotspot mode but it seems proxy servers have their limitations and so im forced to root so i can just hotspot the vpn directly with an app, but after searching i found 3 methods all using superSU which im not comfortable with anymore, all with many steps but in my experice since this phone has got nothing to lose i decided to experiment and boom it worked...

STEPS
1. BOOT PHONE IN DOWNLAOD MODE (power+vold-down+home)
2. FLASH TWRP in the AP OPTION in ODIN (untick auto reboot;very important) then after flash succeeds
3. Pull out battery and boot to recovery (power+vol-up+home)
4. FLASH MAGISK.zip from your SDCARD (Recovery wont be able to mount internal storage so make sure to put the MAGISK.zip in your SDCARD)
5. Reboot and Hello systemless root
credits to this thread where i was searching for root, includes link to 3 methods but mine is the shortest and easiest

I'm unable to start recovery mode. I pull out the battery and after pressing the keys the phone simply goes off. Also I'm unable to enter recovery mode anyway (after turning it off and not flashing anything). That's it, I can't enter stock recovery either.
I tried all button combinations and it just doesn't enter recovery mode.
Never mind, it was probably a faulty button. Pressing with force did the trick. I however employed a bit different path (or perhaps I wrote it down more detailed), which come out more noob like, I'll leave them here for anyone that might use them
Noob, baby steps to root the Samsung Galaxy J2 Prime SM-G532M:
1. Enable developer mode and selected OEM unlocking and USB debug, dunno if it's needed but I did it because in all roots I have seen this is a must.
2. Put the Magisk zip onto a SD card (currently Magisk-v18.0) and put the SD card into the phone. Then I turned off the phone.
3. Turn on the phone into download mode (power+vold-down+home), connect the phone to the PC.
4. Open ODIN and FLASH TWRP file using the AP button (VERY IMPORTANT, uncheck the auto reboot in options, otherwise the recovery goes back to stock I think and the phone will boot into the regular OS, and you'll have to flash TWRP again), wait a few seconds to the flash to finish (odin says PASS! in green).
5. From this screen without touching anything reboot the phone into recovery mode (power+vol-up+home) (just in case press hard the vol+ key). If it boots the phone in regular mode, do steps 2 , 3 and 4 again.
6. FLASH MAGISK.zip from the microSD. When finished wipe Delvik/Cache.
7. Reboot the system. Open the Magisk app (you might have to wait a few seconds for it to appear among on the apps) then press yes when prompted to finish installation as many times (2 times I think). And done, you have your phone rooted.
PD: Magisk can be found here: https://github.com/topjohnwu/Magisk/releases/
As for the TWRP file (twrp_3.1.0-1_sm-g532_5617b.tar), use the one in the link on the OP.

why am i getting an error? it says
"Updater process ended with ERROR: 1
Error installing zip file '/external_sd/Magisk-v17.1.zip' "
can i get some help here?
Good day!
Is disabling dm-verity and force encryption included in the process?
And also, everything works fine but how is that i cannot delete system apps manually? They're returning back after reboot.
Thanks.
Unable to detect the phone -win nor Lin
Hello guys
Something really extrange is happening.
My j2 prime -532G- can't be detected by Windows nor Linux.
The usb is working because it charges the phone, but I can't access the phone at all. I checked all the drivers in Win -google/adb and samsung- and in Linux libmtp/heimdall/etc.
I have tryed different usb -not the original one since i lost it-
Even when i start the download mode, nothing happens.
it there a way to root the phone without a PC? i have tryed also kingroot apk but it is useless.
Thanks

I can't seem to get this phone to go into recovery after flashing TWRP. It always goes into a normal reboot no matter how hard i press the button combination.
Any idea about how to make it reboot to recovery any other way
BTW I was aable to make it go to TWRP Once but forgot to insert the SD card that time and had to repeat the process again and haven't been able to see that TWRP screen agin
Any ideas

J4 plus (J415GB) bricked

Is there anyone here facing same with my situation? today i bricked my J4 plus, Dunno if its hard bricked or soft brick, I can't enter to download mode and system restore anymore. Im just trying to get oreo back because i fell little laggy on my current os (pie). I went to samsung service center and they told to use JTAG to get it fix but its too expensive for me to pay hundreds buck for this.
Thank you
its not bricked. your battery is full drained. i had the same problem and how i fixed!!! i presed all 3 buttons and put usb cable to my pc and my phone. it goes like bootloop starts and shuts. you will wait with pressed buttons from 5 to 10 mins depend how low is your battery. and finaly will go to download mode and you can flash it then!!!
Bricked my J4+
Can someone help me with a bricked J4+?
I wanted to install TWRP, I followed the guide to the letter on how to install TWRP.
After successfully flashing TWRP 3.2.3-0 and flashing RMM bypass zip (without booting to the OS) I also performed a Wipe Cache in TWRP.
I booted to the Samsung OS and the system overall felt laggy.
I performed a Factory Reset, still the system felt laggy.
I decided to use Odin and install the Samsung factory system (thus go back to Samsung OS).
I booted successfully and decided to give TWRP 3.2.3-0 another chance.
Odin resulted in FAIL when trying to flash with the following error: Can't open the specified file (line: 1892)
I tried different versions of Odin (from last to previous ones), different USB ports, I even tried another PC but no success.
I performed another factory reset and now the phone is hard bricked I guess because it will power on...try to get in stock recovery and Erase...and then power off. I can't get to download mode or stock recovery.
Any help I would highly appreciate it.
Thanks.

The part where I had to format the data...I have missed that. Thanks for pointing it out.
I took the phone to a repair shop because it is hard bricked and it needs jtag to unbrick it.
As soon as I have it back I will try again to install TWRP.
Thanks for the help, I appreciate it.

This is a phone from work and I did toggle EOM unlock and USB debugging in order to flash TWRP.
I did not enter any password, face unlock, pattern or sign in to google....nothing of the sort. As soon as I opened the phone from the box tried to install TWRP knowing it will erase everything after TWRP installation. I really hate Samsung UI and wanted to try Lineage OS or another custom ROM which is not laggy like ONE UI.
After installing TWRP the phone became very laggy (obviously I did not perform a format data...my bad) I did use Odin and flashed the corresponding firmware of the phone and it did that successfully.
I tried to give TWRP another shot by flashing it again but I was getting a FAIL in Odin with the following error: Can't open the specified file (line: 1892)
After this I tried to flash again the same Samsung firmware but kept getting the same FAIL and the same error: Can't open the specified file (line: 1892)
I have tried all versions of Odin but the same FAIL and same error.
Now I can't even get into Download mode or Samsung recovery mode.
I press Volume Up + Volume Down and insert the micro USB cable....the phone takes at least 10 seconds to power up (Samsung logo) and then I see a blue screen with Android robot trying to perform an Erase and then fails and the phone powers off immediately.
As soon as I get the phone I will check your link on XDA and try a GSI ROM.
Which one do you recommend...this is a work phone, all I care about is speed and fluidity and it has to be a daily driver.

yeeeahhh. i am knowing that in hard way. you can check user data only if you have ORIGINAL firmware and not rooted phone(mean twrp),if you have rooted(twrp) then flash with or without user data. some firmwares on web can flash with user data, some cant.anyway as i say you can always ask for help.i will gladly help if i can. good luck.

What you're describing are symptoms of a flat battery and a direct boot to recovery.
To boot to download mode plug in the USB cable first then hold vol up, vol down and power until download mode appears.
There is absolutely no way TWRP caused the lag. TWRP runs in its own minimal OS environment and has no effect on a booted android OS whatsoever.
Lastly your device wasn't hard bricked, a device that powers on even if it doesn't boot is only soft bricked.
Usually recoverable using the right procedure.

I managed to boot into the Revovery and perform a factory reset, now the phone booted normally.
I will try and install TWRP.
When these strange things happened the device had over 80% battery...at least that's what it showed on screen.
Now I see that indeed it was flat 0% and you were right to point out that this is a flat battery problem.
Thanks for the help I really appreciate it.

Yes Thanks. I am at 100% battery. Can I ask a few questions on how to install TWRP?
I am on Android 9.x.x PIE.
Install TWRP and immediately force reboot to recovery.
Flash the RMM bypass.
Format data
Boot to Samsung OS.
Is this procedure correct?
Thanks.

It's correct, but if you want access to the data partition in twrp you need to also install the encryption patch.
You will also need to either install magisk or some other patch that disables dmverity.
