Restoring backup - what went wrong? - G2 Q&A, Help & Troubleshooting

Hello,
today I managed to brick my device and restore it to working state, and I wonder at what point I made an error.
So here's what I did:
Had stock lollipop 30b
Rooted using oneclick root+recovery
Installed twrp using autorec
Xposed etc. and used it for a while without problem
Decided to flash something new
AOSPA 5.1.1 seemed like a good choice
Flashed bootstack, that was mentioned in aospa thread, system and gapps
Wow, that was smooth, but I needed my apps next day so I decided to restore my stock backup
Restored backup and ended up with phone in 9006 mode
Later I did some stupid moves that made whole situation worse, but that's not the point.
I backed up and restored everything that twrp allowed me to, so not only system and data, but also boot, efs, modem, recovery, sns etc. Could this be the cause? I didn't change bootstack, because I thought, that I had the needed one (autorec puts kk bootstack, right? and aosp roms also require this).
What should I do to avoid such problems in the future? I'll probably flash a lot, trying to find best possible rom for me, so it's neccesary to now whatto avoid.
And tip for future newbies like I was: if you can enter download mode, then use it, flash tool won't wipe your device data when you're using normal flash. When you've got normal working system to begin with then you can tinker further.
(Also there seems to be no way to recover from demigod critical error, even though it says it enters recovery. Then it's only this method with shorting capacitors on motherboard (fix real hardbrick)).
Cheers,
Marmelada

You can flash the patch (go back to LP from Sombons), flash, reboot recovery, restore stock rom and reboot.

Did anyone's TWRP become broken after updating to 4.4.2?

Did anyone's TWRP become broken after updating to 4.4.2? Thought I'd ask because everytime I attempted to gain access to Recovery Mode, I would get an error (it said something like "No connecrtion"). I had to manually flash TWRP with Wugs and was able to successfully gain access to Recovery Mode again.

I've not updated my Nexus 7 to KitKat yet, but I just noticed on my Nexus 5 that TWRP is broken after updating to the 4.4.2 OTA. I don't get the "No connection" error, I just get the little dead android icon with the red exclamation point. Too bad I'm at work and won't be able to re-flash it until I get home.
You're not alone.

Lacking any and all details about how you upgraded, I would have to say that is to be expected. The OTAs usually directly overwrite the recovery with a new version of the stock recovery.
Moreover, the most recent OTA used that "/system/recovery-from-boot.p" patch file and associated script "/system/etc/install-recovery.sh" mechanism that automatically overwrites the recovery by patching the boot partition image; I think this happens either on every boot (or maybe during a clean shutdown).
So, not having noticed that, I flashed a custom recovery & booted the stock ROM... and next time I rebooted into recovery, I was back at the stock recovery ... WTF?, right?
I renamed those files to stop that from happening. I think some of the recoveries are aware of this and perform similar tricks on your behalf when they "install root" for you, but if you continue to get your recovery overwritten by stock, this is the place to look.
FYI I capture a full nandroid backup of every new stock release, whether or not I plan on using stock. I set them aside (copy them to a PC) so that they are always available.
I do this by:
- TiBu user app & data backup
- make a nandroid backup of my current ROM
- restore a nandroid backup of the prior release of the pure Stock ROM including it's matching stock recovery
- take the OTA and apply it (note everything is COMPLETELY, 100% stock during this operation)
- soft-boot a custom recovery via fastboot ("fastboot boot ...")
- make a nandroid backup of the new pure Stock ROM, including it's matching stock recovery
- flash a custom recovery and either restore a different ROM, or root the stock ROM and move forward with TiBu
This may seem like a lot of work, but it preserves maximum flexibility and safety:
(a) I can roll back to pure stock (any version!) any time I please from my archive of stock nandroid backups.
(b) I never - ever - have problems with OTA installation (including hazardous things like bootloader installs)
(c) I never need to go begging on the internet "please anybody, can you send me file "xxxx" from the stock release "xyz" ? I already have them - all of them.**
hope that helps
** note that TWRP's ".win" files are just tar archives. You don't even need to restore prior ROMs to pluck out individual stock ROM files.

[Q] N910G won't boot after TWRP restore?

Hi All,
Just wondering what's going on with my phone - it's a Galaxy Note 4 SM-N910G with Optus Australia.
Here's the situation:
I rooted my phone using Chainfire method from 5.1.1 Optus firmware.
Then, I installed TWRP, backed up all partitions (INCLUDING EFS).
After that, installed Cyanogenmod. Holy damn, I need to go back to stock...
so...
I booted back into TWRP
I reset phone as usually would to restore/install ROM.
I restored firmware backup in TWRP.
Reboot to system
-- BOOTLOOP --
happens every time i try to restore, and the only way I can use my phone right now is to reflash Cyanogenmod 12.1 nightlies onto it - which have problems (such as I cannot reboot with CM12.1 because if I do after installing it, the phone app breaks and I cannot get past anything because of toast message "com.android.phone" has stopped..., so then only way to get it to work again is to reflash CM12.1 again - this happens about twice daily...)
-- -- PLEASE HELP!
What happens to TWRP backups that mean i cannot restore my stock backup without it bootlooping? and why can devs not post a clean stock flashable ZIP copy of stock firmwares? Its great having all these mods, but how about something that doesn't require umpteen thousand bloody applications to reflash your phone with? Whatever happened to a simple ZIP? when I see ZIPs, devs see thanks buttons being pushed!
-- THANKS

This http://forum.xda-developers.com/note-4/help/n910c-to-stock-rom-cm13-t3321132 :good:
One possible solution is to flash the appropriate stock rom via odin. After booting, install twrp and root your phone. After this you can restore your previously saved stock rom via twrp.

Sorry no help from me but I have a similar problem. At some point mine quit booting to TWRP and I got a huge OTA update a few days ago and every time I try to boot into recovery it ends up in Stock Recovery only after going to little android saying installing updates(it fails & eventually goes to stock recovery.) I did a reset and still have 5.1.1 installed and still have the same behavior.
I have the professional version of the unified toolkit and it says if it is still booting into stock recovery select options 7, 3 which I did but it didn't fix the problem. I think what's getting me is it thinks there are still system updates to install.

TWRP or Other issue?

I"m having issue with flashing roms, kernels and restoring on my device and i'm not sure if its cause a process was done incorrect and/or a TWRP.
I have a 2017U. Bootloader is unlocked, TWRP 3.1.0, and currently on stock B19 (no root, via TWRP with Draken's Stock system).
Here are the issues I"m facing:
1. Unable to Restore backup. I've made a backup and selected Boot, System and data. Also selected "compression". Restore shows complete, but device freeze on boot screen (the one says hit vol for more options).
2. Issue flashing kernel. I tried flashing Beastmode (a couple of previous versions up to the most currect R45). I keeps booting back into Recovery. I then tried flashing the stock kernel from Freeza and it still boots into recovery.
3. Flashing Roms. This one is possibly a rom issue, but just wanted to throw it out there any ways in case it's not. Flashed Bad Boys rom. Works fine when installing with SU or Magik, but doesn't boot if it select "no root"...
Any help/advice is appreciated.
You either need to flash supersu, or no-dmverity to patch the kernel to bypass this security feature.
3.1 is also not ready according to twrp thread.

Thanks guys.
Just having a difficult time with TWRP recently. I wasn't able to restore properly on 3.0.4.
Every time i tried to restore, it says i need to uncheck mount system partition read only. Do need to flash the no-dmverity after i restore?

TWRP not booting system

I tried to factory reset a custom ROM, got sent to TWRP then I can't reboot to system from there. Tried a clean install but to no avail. I've looked around on the internet and I think I have to reinstall stock ROM and then reinstall custom recovery and ROM, except if I were to install the stock ROM once again (with sp tools) I need my phone to be turned off, not in recovery mode. So how exactly should I proceed now?
EDIT: Managed to get rid of the TWRP bootloop by restoring from a stock nandroid I've found on the forums, coupled with flashing a stock recovery image using TWRP. Reunlocked bootloader, flashed TWRP all over again and then flashed custom ROM and Gapps. Everything running fine now.
Mods feel free to delete this post since it's solved itself, or leave it in case anyone needed help concerning the same issue, up to you.

can you put a link where you find the stock recovery, cos i've restore stock recovery on twrp but my device keep booting to twrp

Sistem Destroyed

Hey there!
I'll be honest, I don't even know how to start but here I go:
I have a MIA1 since a year ago aprox. when I bought it I rooted it and flashed a couple roms, I usually flash roms mostly beacause of "the volume buttons to skip tracks thing" and I root it beacause I can't live without Viper4Android, so several months ago I flashed Resurrection Remix, wich I believe have the Treble partition system that only works with CoscmicDans twrp. So I think I did everything right and flashed it, but now I wanted to change roms(even to stock as I saw gravitybox runs again) and I couldn't, I got the "unable to mount vendor" Message.
I tried everything, even flashed stock with MIflash and seemed that that did the trick, but... now I can boot twrp through fastboot but when I flash it through twrp and restart to recovery I get "The system is destroyed" wich seems like a very bad message, Its weird but the stock rom runs anyway.
So here comes the question: Can someone tell me what to do to have my phone back to stock, then root it again and be able to flash other roms again? I'm quite sure that it has something to do with the "vendor thing" ,maybe I didn't reverse the treble-conversion or something? with that thing my head just doesn't get it....
Well thanks for reading, have a nice day!
Look, same thing happened to me with that recovery, currently I have no TWRP installed (actually no recovery installed) and I ignore it. If I want to do anything with recovery, I just boot it with fastboot and do what I want because I heard most users can't install TWRP since Pie (or you can, I don't really know).
To flash custom ROM I did following:
If you have any TWRP backup, restore "vendor" partition and untrebalize.
Flash all Pie stock ROMs since January to get modem properly working.
After done, just boot TWRP and flash what you want.
I had few problems with it, but that's how I came from full stock to EvolutionX w/ Magisk and ExtremeKernel
Thanks, I'll do that but, how do I "untrebalize"?
I guess you have to manual load the TWRP on both slots. And make sure you use one with persist function
Thanks, I just read in cosmicdan post that in order to untreble I have to flash in EDL mode with MIFLASH, I'll try that, also, this is weird but I can't find the nandroid backup I made so to restore the vendor part would it work flashing the resurrection remix again? so it creates it again?
For a full stock flash, just use the fastboot version ROM. It takes about 15-20min but will work for sure
