Hi! My first post here (and not a pleasant one).
I bricked my phone by trying to sideload the android 7 september ota update.
I had root and TWRP recovery installed and I thought it would be ok to sideload the update from TWRP thinking that will erase system and recovery. But what I faced was adb sideload to stop to about 30% on pc and the options to go back or reboot system on TWRP.
So being afraid of a brick I didn't reboot and I flashed a nandroid backup (didn't have a vendor backup). After it finished I rebooted system to find out that the phone goes up to 4 dots and reboots.
The next thing I did was to flash a factory image. I flashed both the september and august images by running flash-all.sh with success (no errors) but still the device is in bootloop.
The last thing I tried was this: http://forum.xda-developers.com/nexus-5x/help/fix-nougat-bricked-phones-n6-thread-t3449640
but made things worse and then I could reach up to Google logo. So I flashed back the factory image of Android N August and I can reach again the 4 dots.
The odd thing is that when I flash TWRP I see a supersu folder in /. Do you think it affects anything? But system, boot, cache, sdcard, recovery, vendor are formatted during flashing the factory images.
I have the 32gb model and unlocked bootloader.
This drives me crazy since it's a soft brick and I should be able to recover from this.
Any help will be much appreciated!
Thanks in advance!

Just press the volume down and power button at the same time. Should get you into TWRP and then transfer the file you want to install the ROM on and flash it. That should do it. Hopefully this helps.

I did flash the factory image from fastboot successfully without errors but it doesn't boot. Do you mean a custom rom? Im afraid that may do things worse.

If you have your userdata backed up, I suggest you flash everything including letting it factory reset your userdata.
Keep in mind your nandroid backups are on userdata, so move those off the phone first.
One other thing, when you restored nandroid backup, did you use TWRP 3.0.2-1 and did you restore EFS partition? There was a bug in TWRP where it would crash your phone because it overwrote an EFS partition with the contents of another EFS partition due to incorrect filenames.

Yes i used TWRP 3.0.2-1 to restore EFS. Was the bug to that version? Is there any way to fix it?
EDIT: I downloaded and installed twrp 3.0.2-2 and when I try to restore the efs it says "efs2 no such file or directory". The previous version of twrp doesn't semm to have backed up this partition. I only find efs1 in the backup folder. @sfhub can you plz help me? How am I going to find the second partition of efs. Can you plz provide me a backup?

There is some info about this over on the TWRP thread.
Essentially if you write all zeros into the efs partitions, the phone will recreate the data (if you instead of non-zero data, it will think things are corrupted)
I suggest you read very carefully erverything you can about recovering from the TWRP EFS bug. This post will get you started, but I suggest you read the original thread from the 6p forum that is referenced in this post. I haven't done this myself nor have I read that carefully so don't want to give you bad advice and make your situation worse.

Thank you very much! I'll read it first thing tomorrow and I'll let you know what happened.
@sfhub thank you so much!!!! That was it! The dd commands fixed my problem. I didn't know that the EFS partitions could be reconstructed by the system. I thought I was done. Thank you for indicating the TWRP bug. I was not aware of it. I couldn't understand what could have possibly went wrong since everything was flashed successfuly from the factory images.

Apparently, TWRP v2.8.6.2 compressed images to external SD cards are damaged, and it wiped my Recovery Mode and part of my previous Stock OS LRX22G.T800XXU1BOE2 installation.
I was able to Odin a Canadian copy of T800XXU1BOCC_T800XAC1BOC4_XAC, but it isn't working properly on my SM-T800.
Can somebody please point me to a US LRX22G.T800XXU1BOE2?

What do you mean the backup was damaged, what failed and which partition?
You can reflash recovery then just restore system. No need to do a full restore.

Unfortunately. @ashyx - I'm not sure exactly where now. The recovery failure was almost instant (within the first 5 to 10 steps), and I remember that the error occurred right after a progress comment about EXT4. I lost the capability to boot up, and I lost the capability to get into Recovery Mode. My only option was to stay stuck in Download Mode, and hope that my battery didn't die before I was able to get a Odin image re-installed.
It was nerve-wracking.
I wasn't sure if the tablet would be charging while in Download Mode, and there was no way (that I knew of) to get out of Download Mode. I thought there was a high probability that I was about to permanently lose my brand-new tablet.
I paid for a subscription to Sammobile to get an older image installed until someone was able to get me the more recent stock image.
I'm too nervous to try and restore the image again without need, but I will definitely do it if you want me to. I understand the urgency to make sure that TWRP makes good images 100% of the time, and I am reluctant to do anything future to my tablet if I can't make a reliable back-up.
¿GJ?
Maybe your backup somehow got corrupted.
Which partitions were you actually trying to restore? For future reference if you made a backup of recovery don't restore it. Only restore it if you want to revert to a different version.
Also don't worry about bricking your device. As long as you still get download mode you will always be able to recover. I soft brick my tablet on a daily basis lol.
The only thing you need to flash to get into a bootable state is recovery. From recovery you can usually solve most issues. Even if your battery had died you would have been able to charge it and then power it back on. Also the tablet does charge in recovery mode.
Twrp can be a funny so and so sometimes. You just get the one time when it doesn't t behave as you expect. 99% of the time though its pretty solid.
I always find its good practise to restore a backup immediately after making it to ensure its sound. You don't want to wait until its too late to find out its corrupt.

Thanks, @ashyx - Good advice on the partition recovery steps. Normally, I have automatically accepted the three defaults, and swiped. I will not do that anymore.
I have found TWRP to be very reliable in the past: If it's working fine, I always get a good backup. If it's failing on something, I always get a bad backup image, or always can't restore. I haven't had a random corruption yet. There was a problem I saw with TWRP and my Samsung GS3 a few years back where it would corrupt compressed archives, but uncompressed archives were fine. Maybe this is a replay on that problem.
I will backup my current CM12.1 image uncompressed, and then try just restoring my system & data partitions from the previous backup, and let you know what happens.

I can assure you compressed backups should work fine. I have done it countless times. Probably just a one off for whatever reason, could be a failing sd card. You may find the backup is fine and will be ok to restore. I wouldn't be afraid to try again. When a backup fails to restore you usually only get an error message not a sudden crash and reboot.
Try making a compressed test backup by just backing up the cache partition then restore.

Is this backup also encrypted. I have seen that error with encrypted backups in the official twrp. However this was fixed with an update pushed to the twrp repo which I have incorporated into the latest build.

No, it just shows Team Win Recovery Project v2.8.6.2. It doesn't show any Samsung model numbers (If that is what you are asking).
I installed it using your All-In-One Root/Recovery tool.
Ok I think you're actually running an earlier build. I have updated builds below.

Thanks, @ashyx! I'll download the SM-T800 F2FS version right now.
BTW, I've been really interested in installing F2FS. One thing I have been worried about, though, is that once I go down the F2FS path, it may be easy to really mess things up. For example, if I update a ROM, I would always need to use a F2FS ROM, or I might lose all my data - is that right?
Normally you would only format the data and cache partition to f2fs. There isn't much point formatting system to f2fs.
Also f2fs requires a special kernel. Myself and Tkkg1994(Iron Rom) have been working together to get this working properly. Still testing.
We are almost there.
Once formatted to f2fs you would need to reformat back to ext4 and flash a kernel to return back to normal. You could then flash your backup.
I was doing normal stuff when I noticed that for some reason my google account had dissapeared from the device. It is not the first time that happens not only in my N5X, but also on an old S2 so since I'm paranoid instead of just putting it again, though of some malware and decided to restore a nandroid backup I did few days ago after reflashing august v6.0.1.
I was using @jollaman999 's multirom and it's recovery, and the recovery gave some strange errors (got an screenshot but on the device..), after reboot I was stuck on Google logo, after that, the bootanimation dots appear but they dont move, and the device resets.
I tested entering bootloader then recovery, and the original TWRP 3.0.2-1 from the backup had recovered and was working, so I decided to restore the very same backup from there. Checked md5s and all good (only a warning about a ' ' or something but all the md5s were good, it asked me to disable the md5 checking option). Restored everything without a single problem, wiped caches and rebooted.. in the very same situation.
I decided to just sideload the last full OTA from August security patches, and I sideloaded it normally. After sideload, not only the problem persisted, but also the original image that appears when turning on the phone (the warning about unlocked bootloader, which usually is orange) was red and talked about corrupted phone. I just flashed TWRP with fastboot and flashed ElementalX kernel and the turn-on screen turned to be orange ok (wtf?), but nothing got fixed and I was in the very same situation.
I decided to do a complete wipe after saving the data on TWRP, including formatting system, and then sideloaded the full OTA again, again without errors, but I appear in the same Bootanimation start-bootlop status than before.
So I have access to aboot (fastboot) and can flash TWRP and use it, but something is wrong and I am kinda lost, never been on this situation. What would you do guys? The OTA supposedly flashed Bootloader, Radio, Boot, System and Vendor and checked that everything flashed OK, yet the boot animation doesn't even start moving...
The Nandroid restore image doesn't have MultiRom.
Thanks for the help guys.

I'm stuck with the same issue. I suspect the power button, seems like a lot of users have problems with that.
I opened my phone and took a look, but the button seems fine..
Okay, issue fixed.
The problem was the EFS partition. When I restored the backup, it included entire backup (EFS) and for some reason EFS backup on that nandroid does not work, and kills my phone..
I tested restoring everything but EFS from that backup, and then EFS from an old copy... and SUCCESS.
I didn't think EFS could literally kill the phone, but apparently it does.
Also TWRP has some nice bugs, if you restore an entire nandroid backup, it says OK including EFS (but after reboot its stuck). If you restore only EFS, it FAILS (cause /efs2 is not found or something like that.)
@Dees_Troy this happened with both TWRP 3.0.2-0 and 3.0.2-1, I had a nandroid backup where restoring everything (including EFS) gave a success but killed the phone, while trying to restore only EFS gave something like (/efs2 not found) and made the phone not boot. In a rage impulse I deleted that backup -.-, I shouldn't probably if you needed some data, but I was so damn nervous, sorry.

If it was the problem button, you couldn't be on aboot (fastboot) or recovery and do stuff .
In my case it was all TWRP+EFS problem.

If you aren't in my case (didn't try to restore also EFS.. dunno why but last time), your problem isn't probably EFS.
Anyway, don't you have an old backup of EFS? It's the first thing I do when getting a phone, boot TWRP, backup EFS, then backup the rest and save those like gold.

Send it to Google for repairs lol.. (it's a Nexus, a lot of people have sent it unlocked and everything and Google covers it, it's a dev device after all).
Also, thereis a thread from bitdomo in this subforum to flash the N5X with stock LG software, that fixes bootloader problems but not sure EFS, try asking him if he could solve your problem?
I have a backup of my EFS that I made with TWRP, but my bootloader is now locked and I've flashed the LG TOT. I've been trying to fix this phone for days. It's stuck bootlooping at the Google logo/4 colored dots animation.
Is there any way for me to restore my EFS partition? Or am I screwed?

I did it and I must restore the system_image and the stock recovery as written in point 8.
But according to this other thread https://forum.xda-developers.com/showpost.php?p=64299835&postcount=4
in Hidden Content point 13, I must backup the system_image, the stock recovery and the boot image.
I have only backupped system_image and recovery and I can download boot.emmc.win from the second thead, but I wish to ask:
Is it really necessary to restore boot.emmc.win? Now I'm on ViperOneM9 4.3.0
Why @Captain_Throwback didn't mention it in his official TWRP thread?

If I didn't mention it, then you don't have to do it .
@Captain_Throwback can you maybe explain that a little further? I made the experience that people are facing problems if they return from a custom rom to a stock rom and don't wipe their phone. That's why I added the wiping step to my instructions. After that several users reported that their phones didn't boot after they restored the first version of my backups (which lacked the boot.img). Therefore, I thought the boot.img is needed as well and all backups got replaced over a year ago with the current version which includes the boot.img.
However, all this is based on the reports of users who had problems with returning back to stock. I've never faced these issues myself. So if there is anything wrong with my instructions I'll correct them, of course.

I thought it's impossible to backup the stock recovery seeing as twrp is needed to be flashed to make the backup..

Since firmware 3.x you can boot TWRP via fastboot from the bootloader without overwriting the currently installed stock recovery.

@Captain_Throwback can you maybe explain that a little further? I made the experience that people are facing problems if they return from a custom rom to a stock rom and don't wipe their phone.

Not sure what to explain - OTA does no verification on boot.img. So it doesn't have to be stock for an OTA to install. It's that simple.

OK. I guess there was a little misunderstanding.
The current version of my instructions is meant to be used if you want to return to a clean stock system. (In other words the ability to install OTAs, again, is only a side effect.) I never was talking about the boot.img being necessary for being able to install the OTA. I thought you were saying that the boot.img wouldn't be needed inside a backup if you do a full wipe before the restoration and that the phone would still boot.

I'm little confused now.
For installing an OTA update I MUST have an untouched system partition and stock recovery.
But the steps I need to do are:
1) backup apps and settings
2) restore untouched system partiton and stock recovery partition from TWRP, doing a factory reset (wipe data, dalvik and cache)
3) boot the original stock OS, configure wifi and go to Software Update
4) download OTA(s)
5) apply update and reboot phone
6) with ADB start TWRP recovery and backup the new stock recovery and the new stock system_image
7) flash TWRP and new custom ROM
8) restore apps and settings from point 1)
So, is it possible that at step 3 my HTC cannot boot because I didn't restore the boot partition (I'm coming from ViperOneM9 4.3.0)?
Or is there a simpler method, without backuping, wiping, restoring?

Anyone can confirm me that my previous steps are right?
So I may uodate to Android n without doubt
Thank you very much
I accidentally flashed an image to the super partition with twrp thinking it was the system partition (it technically is tho) and it bricked my phone and messed up twrp.
Only stock recovery works but the stock recovery cannot fix it by installing a full ota from a otg drive.
I do have a backup on my phone but it is inaccessable.
Could anyone please send me a backup of the super partition or have any idea on how to fix this?
(I tried to use edl and backup my data to recover my backup of the super partition but it seemed like it needed a programmer binary from qualcomm)

Don't suppose you figured this out, I'm having a similar issue.... Have just seen TWRP now supports dynamic partitions which I guess might help?

If you fastboot to TWRP you can install one of the full updates from the site. The update zips ( at least the full versions downloadable from the red magic.gg site will be enough to get your phone's working again.
The zips are official, so they will overwrite your recovery when flashed, but flash just the same without error over TWRP. Make sure you backup your data partition, and do a full wipe before so you can start fresh.
Thanks for that, I don't actually have the Red Magic, I did a forum wide search for the issue. Was hoping the fix would be similar for my device.
My phone doesn't have TWRP yet (Oppo Find X2 pro) ?
My Question is About Twrp, if i make a Back-up of my system completery, and install a ROM and not liked her or bricked my device (Mi a2 Lite) i can take back again, right? without install a ROM stock? Thansk for Answering ? i make one time but Using a Clockwordmod on samsung Old i bricked the device and i Restore a Backup and Back
Sorry about My english bad
Yes, but use unofficial TWRP from ROM section not the official one.
Backup boot, system image, vendor image and data.
Works for custom ROMs, not sure about stock ROM.
Also backup EFS and persist once in case you lost IMEI or sensors.

I'm surprised that unlocking didn't delete your data, for me it did and it usually does.
For TWRP use fastboot boot <filename>.img to boot it and then flash the zip.
Normally that doesn't delete data, but always backup important data first.
I'm not sure how good TWRP handles encrypted data...I'm always unencrypted.
Before TWRP backup people say to remove pins and maybe fingerprints first (there are zip files for that) because then restoring will work better.
Good luck, happy flashing and first search and read if you are unsure.
