[Q] Samsung Galaxt Tab 2 7.0 GT-P3100 bootloop issue - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi,
I have a problem with my Samsung Galaxy Tab 2 (GT-P3100) that has it in a constant boot loop. PLEASE NOTE: I have gone through and tried all the different fixes here and from youtube and nothing seems to work.
TRIED:
- I have tried a hard reset & have wiped cache- to no avail.
- I am not able to uninstall NoRoot firewall or the AVG anti-virus or any application. I suspect that it has something to do with the NoRoot firewall, but even if I uninstall it in the few minutes between boot loops, when it reboots this as well as all the other apps I uninstalled and their cache are intact!
- I have tried changing the developer option to "USB debugging" and "use mock locations", however the moment it reboots or I am in download or recovery mode the setting is back to normal.
- I have flashed different recoveries using Odin but to no avail.
The recovery packages I have used:
1) P3100_CWM_RECOVERY-6.0.1.3_SUPERSU-0.96_BUSYBOX-1.20.2.tar.md5
2) philz_touch_6.57.8-p3100.tar.md5
3) CF-Auto-Root-espressorf-espressorfxx-gtp3100
4) kyleopen-cwm5-v3.tar.md5
Another thing that might be of help is that if I try to install a recovery from external storage, I get the error "E:signature not verified".
Seriously frustrated now! Could someone please help me sort this out?
Thanks a lot!

In cases of constant bootloops, I go back to stock and do all over again. Maybe something is corrupted there.

Pls help!!! Battery mod bricked my phone :( PLS!!

Hey guys
I have a Samsung Galaxy S. Last week I tried installing a battery icon and after installation, it rebooted my phone. It's now stuck giving me the message titled, "Factory Test Failed" w/ error,"no package was found that provides the factory_test action‏" I have the "Confirm" button, but everytime I click it, the same msg pops up again. This happens after the Galaxy and rogers logo loads. I tried going to recovery mode and clean up my user data and cleaned up the internal SD, but nothing seems to work.
I don't have my USB in debugging mode, so I am not sure if Odin is going to work on it. Any help? I did upgrade it to 2.2.
You may have to reflash 2.2 to get everything back to stock and/or do a factory reset within recovery if you can
You crashed your phone - try to reinstall the software.

Weird problem. Cannot factory Reset. Phone keeps restoring previously installed apps.

Hi There,
I have been having the Samsung Galaxy Sl for 2 months now and the software kept crashing. I went to privacy and opted for a factory reset. Funny thing is no matter how many times I do a factory reset the phone restarts, and installs all the apps which i personally installed again. This is not a google recovery problem where all data is backed up in google. But the apps just magically reappear even after formatting the internal sd in recovery mode and reflashing it to the latest firmware. I am at a loss. I got a shock that even after reflashing my firmware to the latest 2.3.4 JKPJ5 it still reinstalls apps such as AVG, the BBC News, Cool reader.. And even my old wallpaper again.
Steps I have taken:
1) Formatted internal sd
2) Used recovery mode and wiped partition and cleared cache
3) Did factory reset and even installed a new firmware.
I have done everything. Pls help. My home button is also not working and the all the corrupted data from my old installation also comes back
Even when I restart my phone, any new apps i install vanish and are again replaced by the old apps.

Thanks.
Funny thing is i tried the reset codes. And only some work. I tried the reset code *2627*3855# . But I get an error saying its a connection probelm or invalid MMI code.
Sorry bangalorerohan. But I am not getting any replies in the Q&A section. I will just continue here for now..
Tell me the method you used to flash the new FW! I will tell you your error!
The probelm began before I even considered flashing my firmware. The sd card will be unexpectedly removed causing forced closes. Did a factory reset using the privacy menu quite a number of times for a few weeks. It helped for a while but the problem will always reocurred though. Then suddenly, factory resets stopped working alltogether. The phone will delete new apps i install every time i reinstall them and reinstall apps which i uninstall every time i restart the phone.
I thought flashing the firmware will fix the problem. But even after flashing the old apps and settings keep coming back.
Here are the steps I used to flash.
1) Removed sim card and micro sd card.
2) Restarted phone in download mode.
3) Run odin and plugged phone in Usb port
4) Checked Repartition, Auto Reboot, and Reset Time boxes.
5) Downloaded pit files.
6) Waited for it to pass
7) Pressed reset
8) Took phone out from usb port, took out battery and turned on download mode.
9) Flashed PDA, PHONE, AND CSC files. By ticking Auto reboot and reset time checkboxes.
10)Clicked Start
11) Waited for pass and started again.
I even tried using the recovery mode to wipe everything but still had the same problem. Apps and settings still keep reocurring from the corrupted android 2.2
I have done everything and am hoping for a solution for this frustrating problem. THinking of reflashing to android 2.2 and sending my phone to samsung for warranty.

I think you have done everything correctly. Maybe it's a hardware problem because your sd card keeps unmounting. Have you dropped it? They best way is to send it to service center for repair.

reflashing back to froyo
Hey guys thanks for your help. but the problem seems to be related to the hardware. I am reflashing my phone back to froyo and sending it to get the warranty. But after reflashing there seems to be another problem. I cant receive calls anymore. But i can make calls..
I need to know if samsung can find out if I have reflashed my phone because I am afraid that my warranty will be void. Is there anyone with experiece regarding samsung warranty?

play dumb, dont mention you flashed, tell them you tried to update with kies and since then the FW is acting up, you can't make calls anymore etc
Interestingly... i have exactly the same problem. I have had this problem for abt 4 months now and i have tried everything (except sending it back to the repair centre). I don't think its a hardware problem but more of a bad flash somewhere in between.
i have been searching the net for ages for a solution... have yet to find any.
Hi all:
I've got the same problem!!
Has any one a solution? I'm crazy with this.
Why do i keep posting on threads that have already been resolved!!

Samsung Unusual Between Boot loop and Softbrick? Data recovery.

Hey guys,
Is data recovery possible after a flash? Also, what is wrong? I have searched but no answer directly hits on this. I am not a tech guy- Biology- sorry for that ahead. To the issue, I dlowded a software update to my Galaxy s3.....and boom froze on Samsung screen. I can turn phone off and on. It would not boot past Samsung. So I went into cache partrition, and tried a system reboot- cannot. So then I seen a program that supposively recovers data after factory reset if you do nothing else to the phone. However, problem I hit te dreaded factory reset- nothing. Over a software update? My computer is not recognizing the device. So I went to Samsung, they tried installing software, however, the computers were recognizing, but not connecting. One tech said they did not have flash- I went back again, the othertech said they did. Anywho, after 4 days, I forked my phone over to a repair guy. He I believe tried Odin- as it currently sits in odin mode. Now it was getting into download mode- but ow I have this message- " Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." A samsung guy mentioned it might be able to be flashed, as my concern data- not backed up. This info is pretty important, as I have several contacts and mssgs. The two modes my phone can go into: Odin and recovery. I could really use the help, on both saving data, and getting the phone to fire- as it might be able to- but data?
Thanks in advance.

Before or after the a Flash? Thanks for the reply.

Ready to throw my phone in a river.

I've come across a problem that's frustrating me to no end. I've been rooting phones for a few years now, usually older models. A friend asked me to root his newly aquired S6 (canadian model, eh), shouldn't be an isssue. I do the standard issue Enable Developer, wipe data/cache, install root and rom, and call it a day. I go to reboot it, and it's in a boot loop for the Samsung screen. I've had boot loops occur before, I'll take care of it.
I've been at this all day (10+ hours), and still don't have a way to escape this boot loop. Problem is that I didn't know about the Reactivation Lock that was still active when I attempted to root. Here' what I've attempted:
- Uninstall/Reinstall USB drivers several times and different versions. Phone will still not show up under ADB Devices and not detected by windows or toolkits (but will still register via Odin).
- Restore from backup: will only boot into stock recovery mode, no option for restore.
- Reinstall Firmware via USB OTG - "USB access is disabled"
- Install other roms, always fail or are denied access
- Update/Change kernel , see above
I could list on and on all the little tricks and toips i've tried from the internet, but what it essentially comes down to is I can't install anything onto the device due to the device not being recognized or being blocked by a permission, and yet I can't get into the actual Android OS to disable/Enable any permissions. Factory reset does not fix this loop, nor does clearing caches. I've tried sideloading, pushing, and various other means to get into Android, but nothing is working. Help?

When connected to Wifi apps download and install automatically

I have a Sprint Samsung Galaxy SPH-P500 Android ver. 4.1.2 Build JZO54K.P500VPBMB3 Kernel 3.0.31-929664.
It was never activated. I tried to have Ting and Sprint activate but both were unable to. One day it started downloading an upgrade. Since then every time I connect to Wifi it downloads and installs dozens of apps. I have uninstalled them and have done a factory reset 3 times. I have installed Malwarebytes but it doesn't find any malware. Nothing I do seems to stop the downloads. So many apps are downloaded it makes it hard to use the tablet and it slows it down. This tablet was rooted before trying to activate and I thought that may be the reason we couldn't so I unrooted it. I have tried to root it again but it won't root. I have tried to boot into safe mode but it doesn't work by holding the power and volume down buttons. When Ting was troubleshooting, they had me use the calculator to boot into the safe mode but I forgot how we did it. I think I may need to flash the factory rom but I not quite sure where to start. Please help!! I am just learning where things are on the tablet even though I have had it for a couple of years so please don't use too technical terms.
Thanks
this is done by google play
go in parameters & disable this option

Thanks for your reply. Is this Google Play Store that does this? Sorry to be a noob but how do I get to parameters to disable this.
Thanks for your patience.
start google play (not wifi connected)
choose parameters option
regards
I have rooted the tablet with Kingroot and have uninstalled or disabled almost everything, but still have the issue. Everytime I connect to wifi, apps are downloaded and installed automatically. Does anyone have any suggestions? If I should install the factory rom, please direct me to where I can get the file and the directions to install. Thanks
OK
Thanks for all the suggestions. Nothing is working. Now when I turn off Wifi, after a second of two, it comes back on so I can't stop all the apps from downloading and installing. The apps use all my memory so if I try to do anything the tablet is slow and there is always some screen popping up. If I install the factory rom, will that get rid of everything and put it back to original? Doing a factory reset doesn't help.
