$20 to anyone that solves my problem.. (will pay through paypal)
I have a Verizon Galaxy tab that I had received for free from Verizon on a concession line.
Model: SCH-I800
Frimware: 2.2
I know my way around Android and rooting, but I had NOT yet rooted the Tab. Everything was going fine up until two nights ago when applications started to force close all the time. So I backed up my stuff and went to Settings -> Privacy -> Factory Reset. The Tab restarted itself and brought me to a black screen with blue text that says "Android System Recovery <3e>" at the top. I scroll down to where it says "wipe data/factory reset" and "wipe cache partition". I select both of these and then restart the tab.
The Tab restarts and looks almost exactly as before. All of my data and programs are on there, except it makes me go through the user setup like I was turning it on for the first time. Almost any program you go into at this point causes a force close.
So I went online and found that I could flash the stock firmware back on with Heimdall. I flashed the stock firmware on and figured all was fixed. When the tab booted it looked the exact same.. Still had all the programs on it from before, but this time made me call Verizon to activate the Tab. Then it forced me through the initial user setup again..
I went and deleted all third party apps of the device and simply turned it off. When I turned it on, it had reverted back and had ALL of the apps installed again!
It is obviously booting up some sort of saved image every time I boot it up.. Anyone that can accurately get me to get this thing back to factory will receive the $20 reward via paypal.
Cheers

If you haven't already, try this:
Remove your memory card.
Press and hold the Power button until device powers off.
Press and hold the Volume Up key then press and hold the Power button (simultaneuously).
When the Samsung logo appears, release the Power button only.
When the Android system recovery screen appears, release the Volume key.
Press the Volume down key to select wipe data / factory reset.
Select Home.
Press the Volume Up key to continue.
Ensure reboot system now is selected.
Select Home.
Yes, I have tried that. Tried it again without the SD card and the same thing happens. It restarts at some sort of image that was saved on there from a few days ago. It makes me go through the user setup but it still has all of my old apps.
I personally use Odin not heimdall and not sure if Odin works with vzw tabs but I assume it does. When you reflash make sure you have a full reflash (pit/PDA/CSC/modem) and make sure repartittion is checked. I don't see any way info could be left after this

I looked into trying to flash the Verizon Tab with Odin, but couldn't figure it out. The stock firmware files from Verizon are:
zImage
system.rfs
Param.lfs
cache.
I followed these steps in Heimdall..
The zImage goes in both the Kernel AND Recovery slot.
The system.rfs goes in Factoryfs
The Param.lfs goes in Param.lfs
and the cache goes in the cache slot.
What slots do these files go into in Odin?
$30 for fix.
I'm in the same boat, any help would be appreciated..
I've been through the heimdal process with no luck. My tab does not fully wipe/reset. It retains root and 3rd part applications that constantly force close.
If this is a recovery file in the system, can someone help locate it? I've tried everything I can think of.
I've got this same issue. Heard somewhere I need to "fix permissions" on all the apps... uhm, time to go digging through XDA!
You need to flash the kernal to something that supports CWM ... that will allow you to wipe the Davlik Cache .... all my issues with FC have been solved by doing that
I used this kernal - KhasMek.Voodoo.Plus.CDMA.Tab.v5.OC

Well this is my 1st post so first of all hey everyone
I just spent a week in Amsterdam and my phone restarted twice, different times different days and I dont remember what I was doing with it back then.
But as I landed back home I put the phone back from "Airplane Mode" and went on to toggle "Cellular Data" on.
The second I pressed the cellular data shortcut on my the phone restarted itself but this time whenever it would finish the screen would be on but fully black and sometimes it'll show battery precentage at the top but then will restart again in an infinite loop.
Sometimes it'll pop up the "Optimizing Apps" window and will go through all 24, upon finishing it will restart once more and do the same.
I tried using the bootloader and it worked (the bootloader that is) but the phone would do the same thing even after Rebooting from there or shutting down from there and then turning back on.
I contacted tech support on chat but they couldnt help past telling me to go to bootloader and reboot, said I should factory wipe when it failed.
Also tried wiping cache but to no avail.
I have no backup of my phone (wanted to do one before the flight but got lazy and I suck for not doing one sooner) since probably October and google doesnt backup my contacts properly for some unknown reason.
I already downloaded Android Studio with everything included for me to try using adb to sideload stock without wiping but its my first time and I couldnt get it to do anything at all...
I already got the official stock .gz file from the motorola website.
Anyway here are the specs to my phone:
XT1575
Everything is stock. didn't root or change recovery once in my life.
Was fully updated and had plenty of drive space (I have almost 128GB with the 64GB version + 64GB SD)
I'm really lost here so help will be very appreciated.
Thanks in advance,

Start with a full wipe and if that doesn't work flash the stock image. Not sure what your question is though as you never really say. Once fixed I would unlock and make a backup so you don't have to deal with this again.

The thing I pretty much want to know is if theres a way to either backup the phone now with it connected to the computer while in bootloader or recovery. or a way to flash the stock rom without wiping which I read someone did with his tablet. I cant post source normally because I'm a new user so here it is but change spaces to dots: schnouki net/posts/2014/08/13/flashing-a-stock-android-image-without-wiping-user-data/
Also while in recovery I noticed 2 options under wipe: 1. userdata only. 2. userdata+(insert something I dont remember here) and I was wondering what gets deleted in both? if I delete only userdata what data will remain? something helpful?
Sure you can try flashing without wiping data but being locked I personally wouldn't risk it. No idea about backing up in your state... somewhere I remember a thread on backing up without root try searching in q&a.

Out of curiosity why shouldnt I try flashing with no wipe if ill lose the data anyway? worst case wont I just have to wipe after it fails and flash again?
And I will try thank you
Do you have any knowledge about the 2 wipe options?
Thanks in advance
Well I tried turning the phone on and it took a couple of minutes before loading to a fresh start. It apparently wiped itself on its own. Managed to restore almost everything.
Anyhow the phone takes too long to boot now. Was even stuck at boot and I had to restart it.
Anyway to fix my software? Or at least check for corruption?

Just posted this on Lenovo forums, if someone here can help me i would appreciate :
Finally received the Nougat update today via OTA, I had enough battery and space internally and SD so i decided to download and install.
After the install finalized the phone is boot looping, it won't stop, i cant even turn off the phone! I already tried removing the SD and SIM card but it keeps boot looping!
What can I do? I waited ages to receive Nougat and my phone is bricked!
Very important note: XT1572 (Style) I never installed any custom ROM, i never rooted my phone, i don't even know how to do it...so that is not the problem.

Press the power button. Keep it pressed for about 10-12 seconds. Maybe this will help. If this doesn't help press the volume down button and keep it pressed (while phone is bootlooping) it will take you to bootloader menu then press volume down button until you see recovery. When you see recovery press the power button. It will show "no command" then press the power button,keep pressed and press the volume up button twice it will now show you recovery menu. Then navigate using volume button and erase all data. Maybe this will help.

Looks like your bootloader is locked. Sorry but with an locked bootloader i can't think of any ideas.( Don't try to unlock your bootloader unlocking it will erase all your data and void your warranty). You can wait for official fix or take it to a Motorola official repair center. I am not sure that erasing all data will fix your device. And erasing your data won't restore marshmallow (did you write lolipop by mistake? Because you can ota to nougut only from marshmallow i think). It will still be nougut.
Can you tell me how much it boots before restarting. does it shows the boot animation fully?
If it shows boot animation fully than maybe erasing all data can fix it.(I can't say for sure)
I will recommend you to wait for official fix.(If the data on internal storage is very important).

Sadly, warranty expired and here in Mexico will cost me tons of money to repair, I would rather buy a new phone.
About your question:
1. It shows boot animation fully, I can even see the main screen for at least 1.5 seconds (where it asks me for password)
I'll have to try to erase all data, i need my phone for work purposes i cant wait Lenovo for an official fix, im sure it will take AGES for that...f*ck them.
By the way, here's the official response of Motorola Support in Lenovo forums:
It's correct to try removing the SD and SIM cards to attempt to recover the phone. Since it did not work, the next step is factory reset. Are you still able to access wipe data/factory reset in recovery?

JM

Again, thank you mate for trying to help me, i really appreciate :good:
A factory reset may fix it if borked data already on the phone from the previous version or an app is the cause.
I'm gonna have to say a factory reset is going to be the best route as I've had bootloops before with this phone and factory reset has always fixed it.
You "could" try plugging the phone to a computer to see if you can get MTP running and access to the partition and maybe that might stop the loop. During my WM/WP days when flashing my roms and radios, accessing the partition via MTP mode stopped the bootloop.

So far you are the first with bootloop - will not be a fix.
I haven't stock recovery and don't remember - is there option "backup"?
Did you have "google photos app"? You should have all photos on google drive. Check it with pc(www.google..).
Only factory reset you can do for help.
More option has authorized service.
With locked bootloader you can't do anything more.
Thank you all, you were right, I just wiped data and phone is working again, unfortunately lost many important pictures that wasn't saved in the Drive :'(
Anyway, I'm testing nougat, looking good atm
You learned a valuable lesson. Always have more than one backup and always use an SD for the camera. Glad your phone is working again .

^^^ THIS!!!
People need to consider phones for what they are... a big chunk of plastic, metal, and GLASS that we fumble with hundreds of times a day. You need to anticipate it will break, brick, bootloop, get lost, stolen, have an update fail, or whatever once in a while, they are not infallible and neither are we. Be prepared, it doesn't take much and it isn't complicated.
Pictures seem to be the most important things to people... INSTALL GOOGLE PHOTOS and set them to backup automatically, it is super easy, and assuming most people charge at home every night, the most photos you would ever lose are 1 days worth. And go to https://photos.google.com once in a while and open the app once in a while and see if they are backing up.
Install an SD card in your phone, even if it's a little 16GB or something, set it up as portable storage (important), and set the camera to save items there instead of internal memory... This in combination with the above measure will be a 99.9% guarantee you won't lose any pictures or videos.
People seem to really like having SMS and MMS copies, then INSTALL SMS BACKUP & RESTORE by Carbonite and setup daily, weekly, or monthly backups of all your text and picture messages to your online service of choice (I recommend Google Drive). Then log into Drive and check it once in a while.
Use Google's Backup Transport, it's built into Android... it will maintain a list of apps you have installed and if the app developer is relatively current with the features of Android, it will backup your settings too, and in the event you need to restore, factory reset, move to another device, or whatever, you can restore all your apps pretty quickly.
Use the Google services and your account, when creating contacts, calendar appointments, notes, etc... Use the Google account option so contacts and appointments are saved permanently to Google and you can access them from anywhere. Use cloud based services like Keep, Drive, etc. so you always have backups of stuff and avoid apps that don't support Google (or other cloud based) storage for important data.
Other apps have some facilities to backup settings, data, and other things related to the app.
Oh, and keep your Google account secure... know the password, have your backup and recovery information up to date so if you lose the password you can reset it via your work email, a SO's phone number, etc. Your Google account is your key to everything if you follow my suggestions.
All of these things can be done a stock device, without root or anything else special... As much as I hate to say it, if you lose data on your device it isn't Moto's fault, Google's fault, or anything/anyone else's issue, but it's your fault. This is no different than the data on your computer, laptop, tablet, or anything else you might own, it takes a little bit of prep and planning to keep from losing anything.
I have thought to myself many times I should write a tutorial on doing these things, and some other common apps and Android tools to backup data and maintain it automatically, but with the way people blame me sometimes for bricking their device with my other tutorials I have decided not to do so.
It always blows my mind how many of my students post on Facebook that they got a new phone and need them.digits. millennials who are sposed to be so tech savvy cannot turn on the features to backup their address book much less anything else.
Maybe as an early genx myself as I grew up with DOS and windows 1.1 beta o better understand the need for a backup....lol
Guys,
I bought used Note 4, that was "broken" in a way that it shutters. Sometimes I have to wait ~1 sec until it responses.
It was with some stock rom 5.1, glitches ware unbearable. Factory reset didn't help.
So I decided to go with other roms. And I found "dm-verity verification failed" and "Need to check DRK first" errors:
Could this have anything to do with it shuttering??
Then I installed TWRP and went with clean Dalvik / Art Cache, System, Data, Internal Storage, Cache.
Installed [ROM][UNOFFICIAL][9] LineageOS 16.0 [tblte][trlte][trlteduos]
Issue still occurs but it's less often. Sometimes it doesn't occurs at all.
And then I ried Havoc-OS
And again issue still occurs but it's less often. Sometimes it doesn't occurs at all.
I have no issues with reboots or permanent hangs. Just those shuttering/glitches/response hangs.
I tried to check logcat but there's to much information and I don't know what to look for.
Guys do you have any suggestions what to look for ?
So I found this video about emmc issue:
https://www.youtube.com/watch?v=5pJ7s9RBtdQ
And I ran this benchmark twice:
And those results seems to be fine, only random read little bit slow, but overall looks good I think.
I also rebooted device and benchmarked it for the third time, just after booting up and results are very similar.
Any ideas what's causing this issue?

Over the years, I've had quite a few N4's. Lost a couple and bought I a couple just for parts. One of then worked well eight months when suddenly it began to has issues for no apparent reason. Even after a complete wipe and a clean official firmware flahing via Odin the issues continued. It wasn't until my N4 suddenly turned off and rebooted inyo a screen I had never seen before. It said "fail to read internal " and "emmc" or "mmc".
With stock recovery you might find some useful information checking "recovery logs"
DM-Verity stands for Device Maper Verification and DRK stands fot Device Root Key. They are part of the security of your phone's deap level software. The common believe that flashing the official factory firmware is a "fix all" is not completely true. It doesn't fix or replace dm-verity or drk issues . However, there are exceptions with mixed results flashing what they call "4files" or in this case 5 files witch includes the PIT ( Partition Information Table) file. I wouldn't recommend this as its a very risky endeavor. The PIT partitions will likely wipe you imei and without that you will not be able to carrier connect your device or even worse heard bricking your device. Its certain not for the novice. This would be my very, very, very last resort if all else fails and if my phone was in worse condition than what you have described.
Before you continue, I strongly recommend making a complete back up to external sd. By complete, I mean checking all boxes when in TWRP. The EFS is not part of a TWRP standard backup.
PS. Its unfortunate the no-opt-encrypted. zip did not have positive results as it did on my Note 4. Even so, its more like a patch .zip than a complete fix.
