[Q] Stuck at Samsung logo during boot even on stock rom - Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting

I have soft bricked and then recovered a lot of devices but this one has me stumped. I tried to install a custom kernel that I compiled myself using odin. When that didn't work I tried to copy the image using dd. My theory is that I wrote to the wrong block device and broke something. When it wouldn't boot I figured it was no big deal, I'll just revert to stock. I have tried flashing the stock rom with Odin and by using Kies emergency recovery. Both seem to succeed but whenever I boot I just get stuck at the samsung logo which displays on the screen forever. I can still get into download mode and recovery mode just fine.
Things I have tried:
- Factory reset (I've done this many times from stock recovery and TWRP)
- Cache wipe (Also tried several times from stock recover and TWRP - in TWRP I tried all the different wiping options)
- Flash stock ROM
- Turn off device and wait for more than an hour (since there is no way to do a battery pull)
My understanding is that the bootloader must be functioning otherwise I would not be able to get as far as I do. And since flashing stock ROM doesn't do anything there must be a partition with corrupt data that is not being rewritten when I install the ROM. Any ideas what this might be? Are there any resources I can use to completely repartition the device?
Any ideas are appreciated.

I fixed my problem so I just though I'd post the solution here in case someone finds this on Google or something.
It seems that I did indeed corrupt a partition that is not rewritten when you flash a stock rom or do an emergency system restore with kies (which I believe does nothing more than download the stock rom and then flash it). I actually had to buy a second device and use dd to copy over all the partitions and then returned the second device
So if you have this problem you might have to ask someone on this forum to give you an image of whichever partition you broke.

weird boot loop issue

ok. the phone will not completely boot into a rom (stock or custom). but i have wiped all data, cache, dalvik MANY times, i have flashed stock kernel and rom from samsung. this will start to load the 4G LTE boot animation and just hangs there all night. i have tried the [ROOT] VRALEC Bootchain - Allows us to Odin a custom recovery method and flashed a stock rooted rom also, just either hangs at the 4glte boot screen or just reboots over and over never getting passed the samsung logo at initial power up.
I have tried beanstown, i have tried everything i can seem to find on the forums. same 2 outcomes. I am using ODIN, and i have never had issues with this before (usually test something out every 2-3 days tops).
is there a chance somehow my partition table is all screwed up? i am lost with ideas at the moment.
lol. has this scared everyone off?
does any one have a stock backup of the NANDROID from their phone? i would be great if they could hook me up as i am in desperate need of one.
bump for ANYONE with any ideas on this first post
did you make a back-up? if not, download root66 to your computer and ODIN to that, if you can get into download mode

i can get into download mode, and i have used odin to do root66. reboot and same thing happens and hangs. also flashed stock kernel.
I do not have my backup because either it has erased my internal sd card, or it is not accessing it.

Cannot get rid of CM10 / cannot reset the device (Samsung Galaxy Tab 2, GT-P5110)

Samsung Galaxy Tab 2
GT-P5110
Android version: 4.2.2.
Hi there, I have a rooted device running on CyanogenMod 10.1.3-p5110, with a custom recovery CWM 6.0.2.7
After 3 years (or so) of smooth operation it started to slow down and getting unstable from time to time, so I decided to factory reset.
I did the factory reset from CWM following the regular regular instructions, however after reset completion the devices booted back to the original CM10, with all the original data (nothing was cleaned at all or reset). I tried several times from - cleaning cache, date, system, dalvik cache, factory reset ... still the same result.
I also tried to replace the CWM with TWRP (GT-P5110_TWRP_3.0.0-0.tar.md5) - same result, it shows success but if I restart to recovery, it goes to CWM 6.0.2.7
If I boot into recovery (CWM) and flash any rom, it shows success and then reboots (guess what) into the original CM 10 like nothing happened.
I tried to flash the stock firmware using Odin. I got an original firmware "P5110XXDMI1_P5110OXXDMJ1_HOME.tar.md5" from a reliable source (sammobile)
Model:GT-P5110, Model name:GT-P5110, Country:Czech Republic, Version:Android 4.2.2, Changelist:1709803, Build date:Wed, 18 Sep 2013 06:13:11 +0000, Security Patch Level: N/A, Product code:XEZ, PDA: P5110XXDMI1, CSC5110OXXDMJ1
Every time I flash the original stock rom with Odin, the ID:COM box in Odin goes green and everything looks just fine but after reboot the tablet restarts to the original CM10. I was using Odin3-v1.85, as well as newer versions of the tool - namely Odin3_v3.07, Odin3_v3.11.1, all with the same result.
I even tried form very scratch - repartitioning the device using a .pit file "signed_espresso_20120220_16G.pit", flashing stock using Odin, same result.
I also tried flashing rom Heimdall Suite - same result
I have no problem to connect to the device using ADB shell and communicate with the device ...
However, I am not any Android guru, so I cannot "decode" what I get.
To me it seems like I somehow messed up my partitions or mounts and thats the reason for the strange behaviour.
So now I am stuck in strange state, which I cannot call a bootloop ... seems like I am running some sort of cached system or someting and I am unable to get out of with any standard tool available. As I said ... device is rooted, running CWM and I can boot to any mode I want ... download, recovery, system.
Any help will be more than appreciated.
You could have an faulty emmc firmware or your emmc reached end of life.
You are from europe? I know someone who can fix it for you.
You can also read the faq on my github userpage for more information about your bug.

Once I had same problem with Motorola xoom and guess what was realy the problem. It was the external SD memory remove it then flash the stock rom.. If problem persists see with Andi
Thank you for your response. To me it also seems like faulty emmc. I have check the frequently asked questions on your blog and the description there exactly matches with what I'm experiencing on my device. Yes I am from Europe, Czech Republic. I have already tried to get in touch with two people who have the proper tooling to flash the firmware (JTAG). Hope I get some response fast and the solution is going to work. Still if you have someone in the CZ that you can recommend I'm grateful for any advice.
@zidane: All of the above steps where performed without external SD card.

@zidane01: thanx for cheerin' up
I have tried to replace my CWM 6.0.2.7 with TWRP 3.0.2.5, 3.0.2.6. from a .zip file using current recovery. Result is the same as described - after I reboot to recovery (using advanced option in CWM) it boots back to the original CWM 6.0.2.7. Flashing latest CM13 (as of 27/9/2016, downloaded from Andi's site) from CWM 6.0.2.7 ends with error. The tablet seems like READ ONLY not matter what I do. Maybe I am doing something wrong. I can describe the procedure step by step in detail, if you wish.

[HELP] Remove boot loop without root & USB debugging?

Hi,
this is my first post on this forum, so please let me know if you are missing any information …
My problem: I'm experiencing a boot loop with my Nexus 5 after having changed its damaged battery. I didn't use it for a long time because of this damage. Now, it does start the boot sequence again, but only to the "circle" animation which it keeps showing indefinitely.
The circumstances:
I never tried to root the phone
USB debugging is not (and cannot be) enabled
I'm completely sure the problem is not caused by the power button (seems to be a common cause)
stock recovery is reachable
an old version of ClockWorkMod Recovery (from this thread) is bootable
three tested versions of TWRP won't boot
What I tried:
I unlocked the bootloader. With both the stock recovery and CWM, I tried to
wipe the device / the cache partition
flash a stock image (directly downloaded from the Google developer page)
flash a ResurrectionRemix image
None of these worked. It seems that the recovery systems are not able to write on or even to mount the necessary partitions. As the stock recovery apparently needs access to /cache for adb sideload, any attempt to flash anything results in an error message. CWM is able to sideload the zip file, but writing the image fails.
I furthermore tried the "factory" (not OTA) image from Google with its flash-all.sh script which tries to also update boot loader and other things via fastboot – every single one of these update attempts failed as well.
So, my question is: Does anyone of you know of a way to get my phone working again?
Many thanks in advance, best regards

Ever fix it?

Need help recovering my phone from bootloop after trying to update custom rom

Today I tried to finally update to the latest version of crDroid, but ended up having a bunch of issues doing so, and after a lot of troubleshooting and trying to fix it, I ended up putting it into a bootloop of some sort instead.
I'm pretty sure the last thing I tried was installing a different version of TWRP to see if that version would let me properly install the rom, and stop my phone from always rebooting into recovery mode.
Trying to turn it on normally or boot into TWRP leaves it hanging on the "Redmi" boot screen, it can boot into fastboot mode though.
I'm guessing that the only way to recover my phone at this point is to flash the Official MIUI rom back onto the phone, but that also involves wiping Data and losing pretty much everything I've put on the phone.
I was smart enough to make a TWRP of the Data folder, but while making the backup, the console said it doesn't include all personal files or something.
How much of my personal data and files can I rescue from the phone in this state, and how can I do that before it gets wiped when fixing it?
Also, I think I really need some help in actually restoring my phone and flashing the custom rom properly.
No matter how much effort I put into figuring out how to do this stuff, unexpected issues always seem to happen, and turns something that initially seemed so simple into multiple hours of troubleshooting.
The only way I think i've gotten rom flashing to work at all was by wiping everything and installing the official MIUI rom, but I don't want to be losing my data every month when an update comes out.
So, could someone please help me get my phone working again?
Edit: I ended up fixing my own issue by ADB flashing on a different release of TWRP, and then installing fcrypt disabler after the rom but before everything else.

Unfortunately, I can't.
Trying to boot into TWRP just gets stuck on the 'Redmi' boot logo.
I just remembered that you can install TWRP over ADB, and that Peter's one says it works even when the system partition is empty, so maybe the issue is the TWRP I installed and could possibly undo this part of the issue over ADB.
It won't fix the issue preventing my from updating my rom, but recovery only is still better than a soft brick.
Edit: That worked, i've put Peter's TWRP back on, and it's launching into recovery mode/TWRP again now
twrp not boot after successfully flash in this rom

In the end, I did try orangefox, and it might have been part of why it worked.
However, the crDroid installation instructions specifically mentions using Peter's TWRP, so I initially used that one.

Thank you for the effort you put into typing up a guide to help me, but I ended up fixing my own problem.
I was able to use fastboot to flash on a better TWRP release, and then get the rom to install properly by installing fcrypt-disabler just after it.

If you can access fastboot, then flash TWRP.... Enter recovery, wipe your system partitions and then flash the Stock MIUI ROM or use the MiFlash tool. Make sure you aren't flashing an older version of the ROM than the onle already installed.

Question Can't boot into anything whatsoever?

resolved​
I was trying to flash a gsi but when I boot into twrp it just goes back to the booting screen again when I press anything, I tried reformatting in wipe before it went back to booting but after that it's even worse. I went into odin and reflashed twrp but same thing. I flashed its firmware from samfx but one ui doesn't even want to boot, it just shows an endless charging logo. The only thing I can boot to currently is the default recovery and download mode. I really need help quick because I need to do some work on my phone.

When you install a GSI, the only partitions you should be messing with are /system and /data.
Did you mess with anything else?
Use Odin to perform a clean flash of the firmware, including a data wipe.

No I don't think I messed with anything else. Also flashing stock firmware again works somehow even though I already tried flashing it before, anyhow, I greatly appreciate your help
PS still not sure what caused twrp to bootloop
