[Q] Cannot boot after factory reset (everything stock) - E 2015 Q&A, Help & Troubleshooting

This is a totally stock XT1527 - never been connected to a computer, never been connected to the Internet. I did a factory reset from the Backup & Reset menu. Now when starting the phone it takes me into fastboot. Checking the logs I see "Failed to validate boot image". I scroll to recovery and it takes me back to fastboot and I see "failed to validate recovery image" in the logs. The bootloader is currently locked and I'd like to keep it that way if possible, because in this case I would like a totally stock phone. What is my best course of action from here? Unfortunately, the phone has been sitting in it's box for over a month since I bought it, so I doubt if I can exchange it for a new one from Amazon.
Edit: I've obtained a copy of "SURNIA_RETUS_5.0.2_LXI22.50-24.1_cid9_subsidy-DEFAULT_CFC.xml.zip" which, if I understand correctly, I should be able to install without unlocking the bootloader. Does this file look correct for an XT1527 purchased from Amazon unlocked? I also notice one command in the installation process is "mfastboot oem config carrier vzw". This doesn't seem correct for my phone as it is GSM. Should I use this command, omit it, or replace vzw with something else?
Edit: Should I be worried about the hardware? As far as I can see there is absolutely no reason this should have happened. For the OS and Recovery to be wiped out during normal operation of a standard feature straight out of the box is pretty worrisome.
Update: This just keep getting stranger. After get thing error and rebooting the phone multiple times I decided to wait until later to do more work. I shut off the non-functional phone as well as an identical phone which did not have this problem. I put the phones in their original boxes and put them in my backpack. About seven hours later I take out the phones and they were both turned on and in the bootloader. I choose the start normally option and they both fully booted into the operating system. The phone which was previously reporting "failed to validate boot image" completely returned to the state it was in before I used the factory reset function. Can anyone explain what has happened here?

[Q] Screwed up my WP 7.5 boot, now what?

Hello everyone.
I ran into a serious mishap with my brand new work phone. I was handed a HTC radar c110 with Windows phone 7.5 to work with, but the phone had a little issue with calls and I decided to do a factory reset to see if it would sort it out.
So I searched on how to do a factory reset, and took a quick run to the bathroom before I could complete it. But my friend decided to finish it off for me, and somehow mispressed some button I guess, because a screen saying "Omega system loader menu" came up instead, with "FFU method" and 2 options, "MTPz" and "TFTP protocol". She took a blind guess at TFTP protocol, and when I came back the phone wouldn't turn on, it keeps resetting every few seconds and only says "TFTP protocol" on the bottom of the screen. Sometimes an image asking to connect the phone to the pc comes up.
I have tried the factory reset after this a couple of times, but when the phone restarts, this TFTP protocol image still comes up and the phone won't start. My guess is I have effed up the OS. What do I do now? Any guess? I don't want to go to my new job on monday and say that I screwed up the phone they gave me yesterday :S.
Any help is very appreciated. Thank you very much.
EDIT: I can get to USB host mode screen (white screen with "enter usb host mode"), and the white screen where you can "image crc" and "factory reset", not sure if it's called bootloader screen? I'm pretty sure I can get somewhere from one of these screens, but I'm not familiar with rom flashing and bootloaders at all.
EDIT2: I have been investigating further and I can now access the bootloader mode (the factory reset one), update mode (the omega system loader one) and usb host mode. I just need to figure out how to flash a rom (preferably an official one, as it's a company phone) into it now.
EDIT3: I got it fixed, not really sure how, but trying different things ended up booting the phone as normal. I am back to having the same problem as before though, but better than having a bricked phone I guess.
any idea what the solution ended up being?
I think reverting back to my original stock rom might be the answer for me, how did you do it?
I've just managed to do the same..
Any help as to how to sort out this issue? TFTP Protocol appears at the bottom of the screen with all the other symptoms referred above.. PLEASE SOMEONE HELP.

Verizon Note 2 MDM lockout...

So i'm helping a buddy out that was having an issue with several Note 2's that were purchased from a company that restricted their employees access to a lot of things on the phone. My friend handed a couple off to me. The first one was not passcode locked and it was a breeze (Basically just enabled USB Debugging). It is up and running. The other ones are passcode locked and when you try to go into wipe the data/factory reset from recovery it says "MDM does not allow factory reset". The Note 2 I'm having issues with in particular has a locked bootloader on KitKat 4.4.2 through Verizon.
I've spent almost literally every waking moment trying to find a way around this issue. I may have compounded it though. I discovered ODIN, flashed the stock firmware in the hopes that it would clear the phone. It did not (password was still in place). I then decided to flash the stock firmware with the .Pit file for an SCH-I605 and made sure re-partition was checked as well as erase nand. After the process completed successfully and the phone rebooted it will no longer boot beyond the Verizon screen. I still have access to recovery and download mode but in recovery its throwing out a bunch of command lines such as E:failed to mount /data etc. I've tried to reflash the stock firmware with and without the .pit file to no avail.
In the mean time I've tried to unlock the bootloader, attempted auto root, and install custom recoveries to see if I could some how get around the MDM issue. I've also attempted to install or flash from ADB and its still the same deal.
Anyway I'm tired, kind of exhausted, and not really sure what avenues I have left. That's where I'm hoping some of you guys come in. If you have any questions for me let me know and I'll try to shed some more light on it for you. Data DOES NOT matter to me so if you can think of anyway I can get this thing completely wiped out it so I can start from scratch it would be greatly appreciated, Thanks.
Is it just one phone with this problem or several? The mounting issues are becoming more common around here, and seem to be internal memory failure.

Well tonight I'll be getting my hands on a couple other test SCH-i605 phones that are in the same situation (Password locked and no ability to wipe from recovery) and I'll put them through the paces to see if I wind up with the same issue and get back with you on it.
The basic issue with this phone is just after trying that repartition with the pit file it doesn't want to boot beyond the verizon logo anymore and thats when it started throwing those errors in recovery. It could be a coincidence I guess.
I've been messing with Heimdall today to see if I could get a custom recovery flashed that way but the phone fails protocol initialization. The only thing I can get to flash to this phone is 4.4.2 and the i605 pit file through ODIN. Nothing else will budge.
I guess the question I really need answered, is there another way to wipe data/factory reset without the option in the stock Samsung recovery and no access beyond the lock screen?
What I have to work with is ODIN mode and whatever is in recovery that is not wipe data/factory reset.
So I did get my hands on a couple other phones with passcode locks that have the MDM lockout within the stock recovery that still fails to flash anything in Odin except the stock 4.4.2 firmware. So I can eliminate the idea its hardware. I have 4 phones here 3 of which have the same issue and the 4th I was lucky enough to not have a passcode. Quick fix to get MDM removed that way.
Again any ideas that are slightly more outside the box would be appreciated. Thanks.
Edit: If this helps the phone that is working that I manage to clean all of that stuff off of also throws the same error in ODIN with or without USB debugging so it leads me to believe there is something I'm actually missing... Time to go read more.
Well, sound like it is more than coincidence. Maybe you should contact Samsung and see if they can help?
Yeah I might do that. I'd just hope they have a one size fits all solution because I have about 600 to 1000 phones to tackle... Hahaha.
The conundrum here is that for the MDM company to release the lock on the phone I have to be able to get beyond the lock screen for the phone to process the request. To get beyond the lock screen I need the psswords that the previous company allowed their employees to put on the phones that for some odd reason they didn't have remove.
Anyway if I get this figured out i'll let you guys know how I got it. Thanks for the suggestion.

Rebooting at HTC screen

Hello. I have a Sprint M9. It had been acting flaking lately (I would try to install the latest update, and it would reboot without installing and report that the phone had recovered from an error and ask if I wanted to send to HTC). Tonight, I was trying to use DLNA to play video from my phone to my TV, I was in settings and gave DLNA permission to access my storage. As soon as I did that the phone rebooted without warning and continues in a loop of displaying the HTC logo, then restarting over and over.
I can get into bootloader, download, and recovery mode by holding down the volume down key. I have tried Wipe Cache Partition and Wipe Data, but the phone still will not get out of the loop.
Phone is stock. I have never tried to root or disable S-on or load my own recovery.
What, if anything, can I do to get my phone working again?
Just tried doing what I think is called RUU? I downloaded the .exe from this site:
http://www.htc.com/us/support/htc-one-m9-sprint/news/
It found my phone, and rebooted into download mode. It tried to flash my rom, but shortly after trying to send the file (progress bar jumped from 0% to 100% in 1/2 second). The utility gives me a Error [155]: Unknown Error. I've tried a couple times and get the same problem each time.
The utility reports I have version 3.41.651.21 and tries to flash to 3.41.651.31
Great, now it is telling me my software has been modified. (it hasn't) The only things I've done is run the RUU and reboot into recover to clear cache/data. Bad NAND?
Well, found out why RUU wouldn't work. Low battery. Apparently it ate a lot more battery than I realized while it was in the reboot cycle. Tried manually flashing the firmware and fastboot told me the reason it was failing. C'mon HTC, if the CLI can tell me there's not enough battery to proceed, your GUI utility should be able to as well.
Still leads to the question of:
- Why did this happen in the first place
- This is actually the second time I've had a problem with OTA, with the phone thinking the system had been modified. So either the OTA failing somehow modified the system before failing, or there's a bigger issue afoot. (as noted above, this phone is stock, I've never tried to root, install a custom recovery, or anything else)

Same thing happened to me. The update that Sprint pushed last Wednesday completely bricked my HTC One M9. Same failure mode that you experienced. Sprint technical center was unable to do anything with it, so they are replacing it, allegedly ( been waiting a week for said replacement ).
I talked to a few other people who had the same problem, by the way. Someone in Sprint's QA team completely dropped the ball on this update.
Well, even after RUU it says my system has been modified and the phone will no longer boot into recovery. Just errors back to Download with the message that recovery couldn't launch.
I've also now got intermittent problems with the com.android.settings crashing. So I've thrown in the towel and purchased my first non HTC phone since the original Windows Mobile days.
Hello there. The same problem has come to my mind and the phone has been off for almost a month. Did you solve your problem? If you could solve it, how did you do it? I sent you above the original stock rom set. Nothing changed. The phone developer rum works. but the original 0pja200 rom is starting again.
my phone soft bricked, unlocked bootloader and S-off. Whether it is possible without blocking bootloader flashed RUU rom?

Stuck in bootload/"Encryption unsuccessful", how to flash/root/unlock?

Hey,
I'm pretty new here, so don't hate on my lack of knowledge^^
Maybe I'm even in the wrong sub-forum
(I think there was a sub-forum dedicated to moto x, but this isn't a device-specific issue, so here should be fine - no?)
Got the following problem:
My moto x (2nd gen) is stuck in a loop. I get to the logo-screen, then it goes to "Encryption unsuccessful" and when I click "Reset", it restarts and fails upon trying to reset.
How I got here:
1) A while ago I wanted to encrypt the phone for the lulz (using its' own encryption-tool)
Followed the simple steps, as in having it charged up, but the encryption did not go through.
Don't remember having it to reset at first, it just booted, even though it had bugs after that:
-whenever I charged it, I had problems turning it back on after charging, had to turn off and back on for it to actually work.
-those notifications on top which one can normally open via sliding down, that sliding down did not work after that.
Eventually I did a hard-reset and it fixed the sliding-problem.
Charging also worked fine at first until it did not.
2) I ended up stuck in a boot-loop that went to the logo-screen back and forth (got to logo-screen, restarted, got to logo-screen, restarted, ...)
Tried to soft-/hard-reset using the VOL- and POWER combo.
The hard-reset itself threw some errors at me, something like "can't delete [whatever]".
Still, after a few tries it eventually went past the logo-screen to the encryption-step.
After another few failed resets and emptied cache via recovery-screen, it somehow ignored the encryption-step and turned on the phone (was a fresh version).
3) Worked fine for 1 whole evening, no crashes/glitches/anything until I had to charge it up.
Then it was back to the broken state.
Note: during 2) I tried to boot with a custom recovery-mode(TWRP), but couldn't get it running.
Then I tried to flash it, but anything I tried to install failed.
I had my suspicions, but eventually I got it straightened out: my phone isn't rooted, and the bootloader is locked.
I did get the code to root it via some steps and the motorola service, but the code did not work as it wanted me to unlock the phone first.
From what I've read, to do that I need to get into the settings and unlock/root it...
Funny thing: I can not turn on the phone to get into the settings.
So - anyone got ideas?
Warranty is gone since apparently my tinkering with the locked bootloader and unrooted phone still was visible and they voided the warranty.
Not sure I broke much/anything with that, though, since it DID work at some point after that (even if it was for a few hours before needing recharging)
Therefore I'm open to any suggestions since the alternative stop would be throwing it into the bin^^
Can I unlock the bootloader without having a working system?
Can I root it somehow without having to get into settings (since I can not turn it on in the first place)?
I did a fair share of reading, but most times the guides just assumed that I already rooted it, or forwarded me to a guide where it said "go into settings and spam the build to get advanced options, then simply root/unlock that damn thing". Tried to find a way to unlock/root it without being able to turn it on, but did not get lucky with the search.
If I could unlock and root it, I probably could go from there. Guides are pretty specific and seem to work for most.
Also, I would try the original android version first before searching for any custom systems.
(that is the smartest way to do, right? since I'm just a user and dont plan on doing more hacking/breaking)
Hope all that above wasn't too much to read
Thx for any advice in advance.
Edit:
Well, after what feels like 50 restarts it miraculously did not send me to the "Encryption unsuccessful" but instead booted like it should (as a fresh version, though - so had to backup).
Now I've turned on the thing in the settings so next time it breaks, which I expect to happen by tomorrow, I can flash that sucker.
Still - anyone knows how to enable all that stuff one normally does via settings some way that does not involve successfully booting it?
I mean, there should be a way to root/unlock it without having to turn it on first, right?
Edit2:
As expected, the flashing part was pretty easy, so I'm now sitting with a fresh android 6.0.
Two days in and it's still working fine, haven't had any complications (except battery draining faster then at the very beginning, but I think that's due to it hanging too much on the usb-cable during all those sessions of me trying to fix it - and generally I've had it charge over night a few times to often)
Still would appreciate any advice on how to unlock developer mode and usb-debugging within the bootloader or recovery-mode.

Samsung Galaxy Tab S6 Lite (LTE) Bricked? Bootloop HELP

Hello, I am new here and I made a huge mistake!
I purchased Samsung Galaxy Tab S6 Lite (LTE) literarally 1-2 days ago and I wanted to root it, I had my smart phone rooted which did not have Knox protections, it was as straight forward as flashing TWRP and use Magisk via instructions I followed.
I make use of "Root" privileges a lot when using my device, I find it very important to my daily life so I decided to risk rooting it, after doing so my tablet was showing 2 errors, that its not using official samsung software and that the boot loader is unlocked, when I unlocked the boot loader using OEM Unlock everything went fine, the option was greyed out and checked afterwards.
During the boot process, it reboots 2 times and it shows a integrity error, integrity and some very long number, I am assuming its a integrity check? I have the exact matching firmware, so I flashed back the stock firmware and... the "not using official samsung software" warning disappeared, it boots me into recovery mode, I choose "reboot" and the device goes to boot looping with the same error.
I was following this tutorial: https://forum.xda-developers.com/galaxy-tab-s6-lite/how-to/howto-unlock-root-galaxy-tab-s6-lite-t4132289
But there are some things I skipped, here the exact steps I took:
Unlocking Boot Loader:
Followed all the steps from 1 to 4 but I skipped the 5th step entirely, the step where it asks you to mess with firmware date and twrp, I did none of that, I will mention that when I was looking for stock firmware to download before doing anything, I was not able to understand the CSC so I didn't know which firmware to exactly use until a software update came up which told me the exact firmware, I accepted the update and download that stock firmware, because my firmware was updated I didn't think that following the few steps of the step 5 would've done everything as I was already off the path.
I didn't do the 6th step as I just checked of the OEM Unlock is greyed out and still checked in the "developer options" section, I assumed that it was a success, not to mention the boot loader unlocked warning that was showing up and yes, all the data was erased and was forced to go through the setup process again as expected.
Root the tablet:
1. I have downloaded the firmware as it says not just for the purpose of rooting, the firmware that the software update told me about, this is the firmware I downloaded, the firmware is a exact match, everything is matching: https://samfrew.com/download/Galaxy__Tab__S6__Lite__-LTE-__/xs5l/SEB/P615XXU3BTI3/P615OXM3BTI3/
2. I follow all the steps from 2 to 11 from here.
3. When I reached step 12, I went to download mode and I look for any messages regarding it only allowing for official samsung images, but I saw no such message, didn't really pay attention to anything else, I just glossed over things, considering there was no such message I assumed that KG/RMM state was good, don't know what it was but it might not have been "prenormal" because there was no message regarding official samsung images, from here I falshed the boot.tar file like in the instructions, that lead me to my current problem I mentioned at the very start of this post.
4. There was no step 13 as I can't boot into android due to "integrity" error I have, right now I have my tablet turned off (thank god I can do that) via the recovery that shows up after flashing stock firmware.
Addition Info:
1. I don't have any data to lose, if I need to do a factory reset or something of that sort, I have no problems doing that.
2. As I mentioned at top, I do have a stock firmware downloaded from this link here: https://samfrew.com/download/Galaxy__Tab__S6__Lite__-LTE-__/xs5l/SEB/P615XXU3BTI3/P615OXM3BTI3/
3. The tablet is: SM-P615 (Samsung Galaxy Tab S6 Lite (LTE), I bought the LTE so I could use it as my phone)
4. At the download mode, the OEM (Boot Loader) state is set to NO and the FFS (I don't remember if its FFS exactly at the moment, something FF I believe, I don't want to turn on my tablet at the moment) was set to NO.
5. The KG (No RMM mention that I could see anywhere) state is showing up as "Checking..."
What do I need to do to fix my tablet? do I need to wait for 7 days? if so how do I do so, like does leaving my tablet off count or not?
PS: I am a self-thought experienced low-level windows programmer, I've been doing programming for over 10 years now, never have worked with Android development but I can attempt to build something from source if necesarry, I know very little about Linux OS as I purely work with Windows and use Windows for everything including servers.
I have done some research regarding that "integrity" error and I can't find any screenshot in google images that matches how it looks on my screen, but there are a lot of them quite similar to it, which basically says "verification failed, factory data reset your phone", in my case I don't have that message, it just says "integrity", but when the boot looping stops and shows that failure I do have 3 options, "try again" and "Factory data reset" and the 3th one I don't remember, I am suspecting that this could be my problem! I believe the samsung just changed the way that particular message is shown (visual change), so I just need a factory data reset and it will work, most likely with the rooted boot.img file! I will attempt this after a few hours of this reply, I may have panicked too early.
The issue has been fixed
Well this is surprising, I was about to do the factory reset but before doing so I decided to flash the same magisk patched boot.img file, when I flashed I saw seeing those 2 warning messages as expected, I was expecting for it to fail after 2 boot loops so I can do the factory reset as intended but on the 3th boot loop the tablet booted up! I was brought at the android setup screen, once I was done with that I checked the OEM Unlock, it was still checked and greyed out, downloaded Magisk Manager and to my surprised it worked! Magisk Root latest version is installed and working, it asked me to allow magisk do some "additional setup", the tablet booted up perfectly fine after that "additional setup", I check root privileges using "Root Checker" and it worked, I have root privileges! I most likely have panicked too soon, sorry for wasting your time! Hopefully this post will be useful to someone in the future looking to root their tablet.
My assumption of what happened: When I flashed the stock firmware AP a second time so I can turn off my tablet, it most likely did a factory reset without me knowing, so when I flashed magisk again before letting it try boot up again, the tablet booted perfectly fine because factory reset has already occured, which brought me to the android setup screen.
