Twrp makes a full backup of the rom so if u do already a backup or stock rom you can restore it from twrp this app has those options

[HELP] Need help is flashing my Phone - Note II

Hello all,
I tried to flash CM 11 nightly version on my Galaxy Note 2 but is unable to do so.
When I try to flash, I get an error message that "This package is for device: t03g, n7100, GT-N7100; this device is t03gub"
I am sure that I have downloaded the correct version but from the above message it seems that I am trying to flash different version.
Please help!!! As I have cleared all the cache and memory, I even cannot boot into system. Cleared all the data for flashing the new CM11 but as I cannot flash now, I am stuck with a dead phone which I cannot use.
Please Help!!!!!!!
Flash Stock
Kindly go to www.sammobile.com and download the correct stock firmware for your phone.
Follow the instructions over there on how to flash. Or Google how to flash with Odin.
Once you get your phone live with stock OS you can go for Custom Rom.
As per my opinion DN4 by Electron Team is the best custom ROM.
Thanks for the help...... I did figure it out.... I had the flashed the wrong TWRP file initially and now rectified it.
Was able to install the CM on my phone.
Have a another problem though..... Phone network is not recognized. I mean by default, the mobile network is turned off and when I turn it on manually, it turns off the mobile network automatically.
Not sure how to rectify it..... everything else seem to be working fine.
Please help!!!
Anyone Help please....
The EFS partition is the culprit. I do not get ant IMEI no. on the phone.
Worst part is that I dont have the back-up too....
Any way by which I can bring back the phone to life?
Please help!!!!

Varun Did you ensure your phone is still rooted ?
Since you Install a stock rom form sams I assue its not Rooted or deodexed coz its stock rom ofcource..
Unless u are rooted you cannot install a good custom rom
Do a CF auto rooting using Odin
Reflash TWRP
Then Enjoy a new Custom rom
Go for DN 4 2.1 with mod v11 :good::good:

You simply dont want tot do that you need to wait for a original ROM that is modded ( just a simpel ROM with root en some uptions disabled like update ets ) why ??? Tot keep your bootloader the way it is now . if you still want original lg ROM you still can like always ( you can always flash a original ROM aslong you dont have a hardware failure ALWAYS !
If iets still locked if flashed normale ROM i dont know , i never go to original.( first thing i do is removing original ROM for ever !)

[SOLVED] Cannot boot into Cyanogenmod, only TWRP. No ROM's working

Edit: Problem has been solved based on instructions provided here.
Long story short I had problems with the newest Cyanogenmod 14 nightly today and had to Factory Reset my phone. Since then I have spent hours installing different ROM's and have been unable to get any to work. They all install just fine, no errors. However I cannot boot into the OS at all. Every time I try to I am automatically booted into TWRP. I don't understand why this is happening after I have repeatedly wiped my entire phone. There is literally nothing on it, I install from scratch, restart... and am booted right back into recovery mode :crying:
Any help is greatly appreciated. I have a reddit thread going on right now as well regarding my problems earlier today but haven't gotten any help.
TWRP Version 3.0.2
Various ROM's I have tried:
cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J9-Z00T.zip
cm-14.1-20161202-NIGHTLY-Z00T.zip
cm-14.1-20161201-NIGHTLY-Z00T.zip
hmm.. try to reboot into bootloader either from recovery or with help of volume plus power button. then flash ifwi, boot, droidboot, recovery and dnx, then install firmware again. if no luck with that. then you have to flash raw firmware using commands

Thank you for the reply!
Rebooting into either bootloader or with the button commands always brings me into TWRP. Nothing else appears to be possible.
Is there another way I can flash what I need? I am not familiar with flashing firmware and am not sure what ifwi droidboot etc. mean, is there a guide you could point me to for this?
Thanks!

Holy **** it worked!!! Thanks so much man!!!
If you were on cm14 then you are on an mm based bootloader. You can only install roms based on that. All of the lp bootloader based roms will do exactly what you described. The other alternative is to downgrade the bootloader to lp.

There is or at least was a bug in CM 14.1 within settings , if did a factory reset within settings ...whether it still there today with latest build ? I've not tested
What it does or did, is render your twrp ineffective , you cannot flash or restore.
Above solution fixed or fixes it fast and you can then restore or install cm14.1

[Help me!] My Zenfone 2 always brick when I try to install a ROM

Hey! I have a Zenfone 2 ZE551ML (Z00A) which always brick when I try installing a new rom. The first time I tried installing RR and so, I downgraded to Lollipop so that could use Asus official tool to unlock my bootloader, then I flashed a TWRP recovery (I'll post the file here) through fastboot and booted to recovery mode. I used the TWRP recovery to then install ASUS rom for Android 6.0 (because the RR thread says I must have Android 6 previously installed) then I restarted and.... got bricked. To unbrick, I used this tutorial from here (one that teached me how to use xFSTK and fastboot to bring my phone back to life) and then unlocked the bootloader and flashed the TWRP recovery, did the update to 6.0 then when I tried to flash RR TWRP says I can't install it (I got error 7) the I reboot and got bricked again. Can someone here please help me?

There's a lot going on here. You need to spend some time reading through the threads. Basically, you can't flash the official asus rom with twrp. It requires stock recovery. And you need to be sure to have the correct bootloader for the custom rom you are installing. Basically, Lollipop roms based on stock rom and Cm13 based roms need Lollipop bootloader. Marshmallow roms based on stock mm rom and LinOS 14.1 based roms need the Marshmallow bootloader. That's where your error 7 was coming from.
Again, read the first post of the Rom you want to install carefully. It should tell you what you need.

The RR rom tells me I need Android 6 but the Official way to unlock the bootloader doesn't work with Android 6. How am I supposed to unlock it? If it helps, here is the link to rom I'm trying to install: https://forum.xda-developers.com/zenfone2/development/rom-resurrection-remix-m-5-8-0-t3507247.

Like I said, you need to read through the threads. Go to the resources and the index threads in the general section. And look at the first posts there. Also find the modder tool thread. It's a very useful multipurpose tool for all kinds of things.

Flashing back stock kernel will fix wifi
Just do it with fastboot
Code:
fastboot flash boot boot.img
Hi, I am facing a similar problem, installed a couple of treble pie roms, all of them had issues last installed one had wifi not working, so I flashed stock from a twrp backup that I had created earlier but wifi kept on not working for some reason .... I tried flashing the original boot.img from my backup as the previous post had suggested but same issue persists .... any ideas how to fix it please??
