[Q] GT-N7100 multiple issues

Hi guys, first of all this is my first post here and won't be my last.
I am an Apple/iPhone long time user and want to tryout Android, just because I think it's time for a change , without knowing if I could get used to the new OS and wanting to spend as less as possible on this "endeavor" I bought a second hand Galaxy Note 2 GT-N7100 from a friend, the phone worked perfectly when I bought it, it had Android 4.1.2 on it and I wanted to update it to 4.4.2, did some research on the net about this (learned about the locked bootloader - this wasn't an issue for me coming from the iPhone) and updated the phone using Kies - and this is were the fun begins.
The update failed, and the phone was softbricked but could still go into download and recovery mode, after reading a few hours on the internet, I used Odin to flash a 4.3 stock rom for the n7100 which I downloaded from samsung-updates, the software got installed on the phone but it was very laggy (with the phone opened but locked, when I pressed the power button it took about 7-8 seconds for the display to light-up, the animations were very sluggish and phone was unusable).
I installed another ROM, using Odin, this time a 4.4.2, with the same results (every time I reset to factory setting and wipe cache from recovery - this didn't help).
I then installed clockwork recovery and rooted the phone then installed cyanogenmod 10.1 which worked almost ok but if i locked the phone after a few seconds the phone would restart, wipe cache/restore factory settings didn't help, i installed it again hoping it would be just an issue with the installation but had the same result, phone would restart.
I've followed all tutorials I could find related to this phone and this issue, installed several patches, reinstalled several stock roms, installed Criskelo rom, all with the same result, the phone is very very very slow and freezez after a while or it restarts after i lock the phone.
So, let me just give u some history on the phone, enumerate the symptoms and where I am right now:
History:
The phone was bought from Vodafone Romania, was never rooted and was never updated (before me ) and still has 3 months warranty.
Symptoms:
- Phone is very slow, unusable
- Freezes after the display is locked
- it is not recognized in windows, when I connect it i can hear the windows connect chime but the phone storage is not mounted, in device manager the phone is recognised as "cdc communication interface" which is not installed - i have the samsung drivers installed, and i have tried on other PC's with the same result, I also tried with several data cables - same thing - the phone works ok when in recovery/download mode
- sometimes when the phone is connected to the PC and the screen goes dark a gray battery appears with a "wait circle" and the phone freezes
- in recovery the phone displays 14 bynaries downloaded and also knox warranty void 1
- most of the roms freez in the language selection screen - i boot-up the phone (after i do a restore factory settings) the installing application dialog appears and then the language selection screen appears, then after 5-6 seconds the phone freezes - the freeze is not triggered by something I do it's triggered by time, after 5-6 seconds no matter what I do with the phone the phone freezes, if it makes any difference, exactly before the phone freezes the display brightness goes to the maximum setting.
Where I am right now
- I installed another stock rom, 4.4.2, it worked acceptable for a few minutes (it got passed the initial setup with no issues) then i left it on the desk, the display went dark and the battery thing happened again and the phone froze, i restarted the phone in recovery, did a factory reset, when the phone started it froze on the language selection screen.
I am at this for about a week now and I have no more ideas and no more patience, and run out of threads and tutorials to read, I am 1 step away of using the phone as a paperweight so please help, any idea would be appreciated, even if it's to enlighten me about what happened and telling me that the phone is bricked.
I am willing to try anything even if it is risky and can totally brick the phone, this is not my main phone and it's purpose is to help me understand android, and help me not make the same mistakes next time.
But, if it's possible I would like to fix the phone because even though it's pretty old it's still an ok phone.

Sorry wrong forum. You need N7100, not the n7000. Good luck.

Phone do not boot after Oreo update

As i installed update and clicked reboot to apply it, now my system do not boot. Phone always stuck on white NOKIA logo boot screen forever. I tried few times to restart it via VOL-UP + POWER, but it always have same result - never boots. Please give me advice how to deal with it

It happened to me too, in December already. Mobile is in service now.
They flashed original fw, tested and returned it with results no fault. Right after switch on and new Oreo update it starts to freeze and produce various mistakes again, so I have returned phone to service. Will complain with seller about exchange.

That really sucks. But what do you mean by various mistakes? Like your system boots, but some functionality is not working? As i said in my case it totally cannot boot and recovery mode i can't enter factory recovery mode by VOLUME UP + POWER on start.

Ach yes, sorry. First it stucked in logo Nokia and rebooting again... VolumeUp+Power does not work normally on Nokia.
It helped procedure found here:
https://forum.xda-developers.com/showpost.php?p=74406267&postcount=34
Then I was able to make factory reset and mobile booted, but worked with various faults.

Did you unlock your bootloader , flashed TWRP and then changed the slot? Slot A to B or vice versa?
If so, then the solution is
How to solve!
I simply waited until the battery ran out
When battery was completely dead and no Nokia-logo appear any more >>
Then I charged the battery 3% juice without booting
and from there I entered recovery-mode with the help of a USB cable.
Holding the volume+ button while connecting the USB-cable
From TWRP-recovery I changed to the other inactive slot
and whooala, that's it!
Edit: I sucked the juice (mAh electric-capasity) out of the battery quicker with help of OTG-cable and an external USB-powerd fan.
Use almost any external max 5volt USB-powered devices available at home, even charging another phone unless the second phone doesn't reverse-charge, this Nokia can be used as a power-bank.

Need help factory resetting my Samsung Galaxy Tab S2(tab has security pin that idk)

Hey everyone,
So I've searched far and wide for a solution but can't seem to find one, anyways my problem is, I bought a tablet(Samsung Galaxy Tab S2 SM-T819Y) off my friend(he didn't know the security pin but he sold it to me for $50 so I thought why not) so now I'm trying to factory reset it so I can use it.
I've let the battery drain overnight(couldn't turn it off before due to the needing the security pin) managed to get into recovery mode once it was off & I charged it a little so I could boot into recovery mode, once booted into recovery mode I continue to select wipe data/factory reset & get this error "MDM does not allow factory reset"
I've attempted to root the device with no success, every solution I've looked at requires me to access into the actual phone & go into settings to change USB debugging, OEM unlock etc. but obviously I can't do that because I can't get passed the security PIN so please if anyone could help me out it would be much appreciated.
Peace out ladies & gents.

Bro i have also same problem when I was flashing twrp through Odin .
My phone is stucking on twrp twrp is blinking again and again.also when I try to go to the download mode it automatically comes to bootloader and then to twrp please bro help if have fixed it

I was just speaking to a phone retailer and he told me how Shamshung M-series phones are getting locked by OEM manufaturer automatically within 6-7 months of usage (he was ready to show me evidence also so I believed him) , he said there is no solution to this So pls guys just an advice DO NOT CONNECT YOUR PHONE TO INTERNET FOR ANY OEM UPDATES,
1> TRY TO BUY PHONE FROM ONLINE STORE (BECAUSE RETAILER WILL FORCEFULLY UPDATE THE PHONE EVEN IF YOU TELL THEM NOT TO UPDATE)
2> FIRST, DONT PUT IN ANY SIM CARD IN SIM TRAY
3> SECOND, DISABLE WiFi (DONT SAVE ANY WiFi PASSWORDS) & TURN ON AIRPLANE MODE
4> THIRD, TURN ON DEVELOPER OPTIONS- USB DEBUGGING "ON" & DISABLE "KEEP MOBILE DATA ALWAYS ON" UNDER DEVLOPER OPTIONS
5> FOURTH, USE "DEBLOAT LIST" ATTACHED BELOW TO UNINSTALL INSTALLED APPS USING ADB
6> FIFTH, ONLY CONNECT TO WiFi FOR FEW SECONDS SO THAT THE OEM UNLOCK OPTION IN DEVELOPER OPTIONS GETS GREYED OUT.
7> SIXTH, FLASH ODIN-TWRP TAR FILE, WIPE/FORMAT DATA, BOOTLOGO PATCHER ZIP, MAGISK 24.3 ZIP, PRISH KERNEL (OR ANY KERNEL OF CHOICE), THEN FLASH TOTSUKA/PIXIE/CLEAN_OS/CrDroid10 (ONLY 3 STOCK-BASED ONEUI ANDRO 11 ROMS AVAILABLE, NO CUSTOM-BUILT NON-ONEUI ANDRO 11 ROMS AVAILABLE NOT EVEN M30S PORT ROM), VBMETA IMG
8> REBOOT TO TWRP, WIPE DATA
9> AFTER DEVICE BOOTS FIRST THING IS DISABLE WiFi & TURN ON AIRPLANE MODE, INSTALL NETGUARD FIREWALL APK THROUGH PACKAGE INStALLER (ALWAYS KEEP NETGUARD ON THROUGHOUT THE PHONE LIFETIME OTHERWISE SHAMSHUNG OTA MIGHT KILL THE DEVICE),
10> DEBLOAT BUILT-IN GAPPS USING ADB
11> INSTALL MICRO-G FROM TWRP
#NOTE: FOR FACTORY RESET SCENARIO REPEAT STEPS 10 & MAYBE 11 TOO.
AVOID VISITING OR USING OEM WEBSITES AND APPS. REMEMBER, FOR GUGLE EVERYONE IN THE WORLD IS A POTENTIAL TERRORIST.

Question Redmi Note 10 Pro stuck in a boot loop

Today I left my phone in a cab and got it back in the evening. But after I got my phone it was stuck in a boot loop (after force restart - power button press and hold - it will go to battery icon and automatically restart after a few minutes and again goes to battery icon). Please see the video to understand the boot loop. Unfortunately, Developer options of the phone were not enabled.
Can boot to recovery but can boot to fastboot.
Can you please help me to boot my phone back to normal or sideload a ROM via adb.
tia

Was able to fix the issue. Followed below steps,
1. Kept phone until the battery fully drains
2. Plugged into the charger and charged the phone up to around 65% while the phone is switched off.
3. Switched on the phone when the cable is disconnected.
4. This time the phone was booted to recovery. No battery logo anymore
5. From recovery, rebooted the phone. But again it was booted to recovery.
6. Wiped all data and rebooted.
7. Phone was booted to MIUI os but had to set up the phone again from the beginning.

Same problem bro, did u resolve it???

I think your battery is empty. Leave it on power for a while and check if its charging. Maybe the charginglevel is too low for booting up.

I hope it was that simple ..it seems probably like a bad update. My gfs phone did the similar today
The digitizer stopped working, I force reset the phone and boom ..recovery mode - Trying everything but it doesn't work. Wipe surely would work but she has pictures and videos so I'm trying to avoid that. Plug it to charging but she remembers it had like 75% of battery ...geez (hoping for a miracle)
EDIT: Probably this happen from the bad xiaomi update, anyway I did wipe the data and as expected it work without an issue, I'll unlock this phone and ditch MIUI (I mean I did it to my phone Xiaomi Mi Mix 2S from day 1 - I hate miui) ..now my gf has a reason to hate it too

A factory reset could be painful, since you would lose everything on the device. I saw a guy tap all over the back of the phone with two fingers, and boom! The Redmi Note 10 Pro boot normally! I tried it on a friend's phone, and it worked.

Hello,I had a kind of a similar thing.
I left my phone to charge and when I was back it seems to be stuck in a boot loop(MIUI14)
Well,I tried to force restart but the same.
Before I go to recovery mode,accidently,I putted the phone in fastboot mode.I restarted it in the try to go to recovery mode but the phone started normally.After boot,it's shows an update compete message,so te problem was from an android security path update whatever.

I have important apps on the phone and I wasnt thinking about a factory reset anyway but hopefully it worked in that way
