Sorry for the late reply,
If you still have TWRP and can boot it, you can just flash a rom via it.
Something like >this< (Renovate Ice)

As jaannnis suggested, boot into TWRP. Load up a custom rom onto your phone, and flash from TWRP. Then proceed with the (custom ROM) OP's instructions on completing the rom install. After that you can boot into system.

First download the ROM (custom Exynos only) you want to flash. You must have Exynos phone, yes? . . . Yes. Do not attempt with Snapdragon phone and custom ROM. You will fook your phone up.
Download any supporting files the ROM OP advises you will need.
Read the instructions from the OP about the flashing/installation order. Perhaps have the web page in front of you, or print out the basic instructions.
As you shared, you can boot into TWRP, so do so and then connect your phone to your computer. When in TWRP, mount your external SD card if the computer does not see the external SD card. Alternatively you can use your internal storage, equally as easy.
Copy over the ROM and supporting files.
Then, in TWRP, go to Wipe menu, and choose to format Data, type yes and that will then formate your data sector area.
Then go back into Wipe/Advanced, and wipe Dalivik/cache, data, system
Now to to the Install menu of TWRP, top left of TWRP main screen, and follow the directions the OP provided for the custom ROM you selected.
After flashing by OP's directions, go back to Wipe/Advanced wipe, and wipe Dalvik/cache.
I am assuming SU or Magisk was installed by the custom ROM, or the OP's directions should have outlined how to install one of the two.
Boot to system, after you followed all of the OP's directions on installing the custom ROM, and wiped Dalvik/cache at the end of all installed files.
Some folks may short cut a few steps here and there, but I'd not worry about that.
If you need more info, it ought to be in the OP's custom ROM thread.

Possible Bricked G2x No NV Flash Back Up

I was flashing CM 7 nightly 49 and now my phone is stuck on the LG logo, how do I fix?

After going through the NV flash process and getting to the last step that says
Keep holding them, as soon as you see "ANDROID" in Green with the new boot logo let go of the buttons.
From there it goes into boot recovery. I then choose from one of the roms I have on my SD card, it loads okay but then when I try to reboot it hangs up on the LG logo again
What am I doing wrong
we def need more info then that like what recovery how did u install the rom did u wipe data then cache then dalvik? then install rom and gapps? did u install any kernels previously? and this is probably going to get moved it should be in general
ok when u go into recovery do u wipe data factory reset, then cache, then go to advanced and wipe dalvik then install rom and gapps and it should boot up fine, did u make a backup of ur stock rom first?

Damn. for one month on XDA you sure do have a lot of posts
On topic: I'm assuming you forgot to fully wipe before flashing the new rom.
If you can get into recovery, it's not bricked.
Read the install directions, you missed a step or got a bad download.. Or a bad build, as they are nightlys...
In recovery, do factory reset, then mounts and storage, select format system. Then install the rom.
Also, get the stock nandroid and put it on your card so you can drop to a known good setup.
I had back it up using rom manager but its on another computer. I took had gotten a SD card with more storage and never transferred it.

You could copy the backup from your computer and make a folder called clockworkmod/backup/ on your new SD and put the backup file in that folder. When you go into recovery, backup and restore. restore - it should be visible. Select it and you should be OK - IF your backup is good.
If not, download a ROM and Gapps with your computer and put them in the root of your SD. Then after a full wipe, flash them.
If you have the latest Recovery, you can mount storage and then cut and past to your device while connected. If not, or if you have any problems moving them, just take it out and do it while it is plugged in your computer.
You have several options - so one of them will work.
Want to thank all you guys. I got it working again.

[Q] First time flashing NS i9023 (serious flasher from SGS,SGS2)

Hey!
First let me say that I know all about flashing SGS and SGS2. Im a proud owner of SGS1 from day 1.
Last week I decided to finally flash my brothers i9023 so I flashed stock 4.0.3 with stock recovery. Then we wanted to flash some XDA stuff and I don't understand these guides...
I found one guide where you get superuser access with one click and usb cable, I did that, then I flashed CWM through Rom manager and flashed 4.0.4 from evilisto (v1.1) and it worked. Now I'm trying to flash some others, like nuhetri reloaded or pixel rom and I'm always getting stuck at boot animation. It just keeps "working" and nothing happens for 5+ minutes.
What am I doing wrong? Please help!
Best Regards
Luka
(in general)in recovery wipe data factory reset, format cache, davlik cache, system, boot. then flash new rom.
with nuhetri i think there is a bug where your not supposed to wipe data coming from another rom only davlik cache and cache then flash nuhetri

I did all that before... Im going to redownload, maybe its corrupted but I doubt it. Is it maybe because I have locked bootloader or something? Beacause I didnt use that long guide with "android SDK" in General, but some other very quick guide. Just plug USB, enable debugging and run some script and thats it.

do yourself a favor, do it the right way the first time and save yourself headaches in the future. its not hard. fastboot oem unlock(bootloader), flash a custom recovery, flash a custom rom(and gapps) via the recovery, then boot up. thats it.
If you are more of a visual type of guy I suggest going on YouTube and search "zedomax". He has some really simple videos on how to root your nexus s, he has a couple videos on how to root but make sure its for a GSM nexus.
Simms got all in a simply way.
Unlock boot loader
Install or flash cwm
install the new stuff from SD card
reboot
Can anyone tell me or please provide a link to what unlocking bootloader does please.
Best Regards
Excuse my ignorance, I'm pretty new to this and I might not be of any help at all... but is it even possible to flash a custom recovery without unlocking the bootloader on the Nexus S?
I followed the instructions found on the NexusShacks.com website (How to root Nexus S or Nexus S 4G on ICS or Gingerbread) without any issues at all (sorry, can't post links due to low postcount :/)
No problems for me, I had zero experience with this sort of stuff but I have flashed a new ROM a every few days now without any issues whatsoever.

I have a custom rom, no Gapps, no root. please help

So my cousin had the this tablet she hadn't us for a while and she asked to to fix it up. Root it put some apps on it blah blah blah. So i rooted it using this: http://forum.xda-developers.com/showthread.php?t=1681155/
Everything was fine and it went smoothly, I had root access, TWRP recovery that it came with and it was working fine.
I wanted to put a ROM on it for my cousin to match her phone so I found this: http://forum.xda-developers.com/showthread.php?t=2584265
So, I flashed the Rom and it was fine. Then I flashed the Gapps and it said that the system partion didn't have enough space.
Here is where I screwed up (I think). TWRP said that I lost root access and i had to fix it BUT i had to swipe a bar at the bottom to fix it. My dumbass pressed the button in the middle of the screen which was to ignore it. I didn't see what i was doing and i messed up
So I lost root or something and when i turn on the device and try to boot into recovery by holding the Power + Vol Down keys it does not work!
Now I have a tablet with android 4.4.3, no Gapps, no root, no recovery. I have tried to factory reset it but the one in settings do not work.
I'm stuck and I need help from someone smarter. Thank you for anything.
Id start again, sounds like something in recovery got messed up if it thinks the system partition is not big enough for gapps

Factory reset & Wipe everything except External Storage from TWRP
Flash ROM
Flash Gapps
Wipe Cache & Dalvik Cache
Reboot
Nothing more nothing less is needed, so if it doesn't work by doing the above, there are other problems
ok so i installed the drivers it easyflasher was asking for and now it asks whether the device is SBK1 or SBK2, how do i find out whether the device is B70 or above... I feel dumb again... It also asks if its in APX mode... i need help again
ok i figured out the easyflasher and i get the recovery but, when im done flashing all the files and boot the device it says that i have to repair root, like before and even if i say to do so i lose the recovery every time meaning i have to go and put the recovery back onto it and do everything again.....
alrighty so ive got the recovery to stick, and i got the KitKatKiss rom which is actually really nice, however i don't have root, i keep trying to flash the supersu file but it does not work. thanks for everything already. it would be nice to have it rooted.......

KatKiss is already rooted by default, you should not flash an additionnal supersu zip.
Just Flash the rom then gapps from the KatKiss thread
wipe cache + dalvik-cache
then reboot.
If you're coming from another rom version, a full wipe / factory reset is recommended before flashing too.

[Completed] Can't boot into my Custom ROM

Hi! I just installed a new Custom ROM for my phone. After 5 minutes I wanted to create a backup. So I started ROM Manager. I entered the name, and hit OK. The phone booted into a crashed recovery mode. So I took the battery out and rebooted the phone. It didn't boot into my Custom ROM. It booted into recovery. So I am stuck inside the recovery mode and can't boot normally.
Phone: Samsung Galaxy Mini (GT-S5570)
Recovery: CWM Recovery
Custom ROM: CyanogenMod
Hello,
If you can boot into the recovery, do a factory reset and flash back the custom rom. And then reboot the device, once you rebooted the device will boot into system. And then you're done!
Good luck!

It still puts me into recovery

Hi, i would like help you with this problem as I myself have experienced it. The things that you should have done are:
1. Always make the backup early on before installing the Custom ROM.
2. When installing a Custom ROM, make sure you have not replaced core system apps
3. Make sure your there are complete symlinks in your ROM otherwise it be hard bricked. Ouch.
4. Before installing a Custom ROM, make sure they are from experts, like CyanogenMOD, and sure your device is supported for updates.
5.[Most Important] The only things to wipe when installing a ROM are : 1. Cache 2. Dalvik Cache 3. User Data, never ever ever ever WIPE your system folder with root access on it. This will always ensure that you will reboot into recovery, and it will be annoying to root your device w/o ADB USB Debugging on.
6. Make sure that there are no system apps missing on your Custom ROM, check for the legibility of the Custom apps installed. Are they pirated perhaps?
7.[Very Important]Always watch a video tutorial for it's errors, and search how to Unbrick your device first before proceeding with an installation.
So that if any problem arises, you will be sure to restore it to it's Stock experience.
8.[Absolutely Important]Make sure that your software counterparts on the PC are compatible and functioning well first before you proceed.
Now tell, me which of the following did you not do?
And if this really helped you a lot, please like. For the sake of those who did their research.

Try fastboot?
Hi,
No one seems to have suggested using a program called fastboot. It involves just installing some essential software on a PC, then running the program "Fastboot" along with the desired options.
I strongly suggest trying this: http://forum.xda-developers.com/showthread.php?t=2277112
I am always flashing ROMs and then trying to tweak them and end up messing up the bootloaders, or somehow breaking the system. And then i try using CWM or TWRP and still there remain issues. However, fastboot has always done the job for me.
Hope this helps.
Someone help me with my problem please ??
Use Fastboot!!!

[Completed] Verizon LG G3 Cyanogenmod Recovery To TWRP

I have Cyanogenmod recovery so that updates auto install. I downloaded the 20151005 update, and hit install. Things went fine until the part where apps optimize. It would finish, then show the Cyanogenmod boot logo for a few minutes and restart optimizing, over and over. I tried downloading the update on my computer and putting it on my SD card to see if it was just the download was messed up, and it did the same thing. I downloaded a previous update the same way, because my phone can't boot into android, and it did the same thing again. So now I want to get TWRP to see if the recovery is the problem, but I don't know how. That's where your help comes in. (hopefully!) Or, if there is a way to fix this without that, that would be preferable. And yes, I already wiped the media partition, cache partition, and did a data/factory reset, which are the only things I can wipe in Cyanogenmod recovery.
Hi
Thank you for using XDA Assist.

TWRP is better recovery. I do recommend it
Yes, I agree. But if you read my post, or at least understood it fully, you would know that I was asking how to install TWRP from the Cyanogenmod Recovery. It only lets you flash Cyanogenmod update zips, and it replaces the stock bootloader as well, so I don't know if the regular ADB method of flashing TWRP will work. I can't break this phone, you see.

I guess you can since CM Recovery is almost a stock recovery.
Since you have 10 posts now, you can directly have a confirmation by posting in the above thread.
