Have you used any kernel tweaks or anything of that sort before? L-speed maybe?

If I am honest I am not sure ..I ran a couple of different roms then when trying to get back to stock this is where it all has gone wrong

I think the roms I used were leedroid and then viper
I think when installing viper it asked to tweak things that I oked

I occasionally get the same error but it has never stopped me from installing a ROM.

could it be because my phone is s on

when i try to instal a rom using fastboot abd i get the eror (9 ru_security_fail zip from usb command ion download mode)

just tried running this ..........TWRP Backup (Untouched System Image + Boot)
all installed then at very end got this .failed to mount '/devlog (invalid argument)
now just boot looping
Does anyone have any ideas before i skim the phone out the window

progress i have reinstalled a rom called rr-n-v5.8.4 resurection or something
i think this is the last rom that broke my phone i can run this now but it seems i cant go back to stock from here
can anyone help or tel;l me how to get to stock from here

I'm honestly not sure but I've had that devlog error before but like @lightweaponx said it never stopped me from flashing a rom. It happened when I kept messing with kernels and i think it has to do with disabling logging (stops device from creating logs to increase performance) but even then that error never caused me issues. Id suggest trying different twrp version if that doesnt work then perhaps you should RUU and retry it all from scratch.
There are a lot of threada and posts to get back to stock search arounr and im sure youll find it

Flash RUU and stay stock untill you actually know what your doing. Post your CID.

I have tried flashing stock ruu using the zip file but it wouldn't work
I managed to change Karnak last night and install leedroid everything went through but then on booting up it asked for decryption

How are you flashing RUU? You need to format data if you get that message. Can you please post your CID? I have a feeling your trying to either flash the wrong RUU or your trying to do it in twrp which you can't.

thats because the rom you are trying to flash has no signature, all you have to do is use a recovery that lets you flash unsigned .zip's, the latest version of clockworkmod recovery that comes with the unrevoked flash tool lets you do this
I did what you said and it worked from what i can tell and it loaded on AuraxTSense. The problem is at start up now it just says loading, this may take a few minutes to complete and just hangs there. I can't do anything with it and i can't change the rom from the recovery menu so now i'm even more stumped.

at witch part is it saying please wait? has the rom booted? did you do a full wipe before flashing? try doing a full wipe from the partitions menu in recovery and re flashing the rom
rebooted it and this time it just loaded up properly. Strange but hey.
Thanks for you help on my previous problem. It's basically the same issue but i've also tried deleting the partitions in the recovery menu. I've tried changing the rom from clockworkmod, nothing is working. It just puts AuraxTSense back to default.

[Q] TWRP unable to find partition size for

Hello Everybody,
i am using this rom 4.3 from a while ago and i wanted to change it to the 4.4 rom
i decided to flash Omni 4.4.2 new rom from this url
http://forum.xda-developers.com/showthread.php?t=2487526
As per the installation instructions i went to download TWRP ver. 2.6.3.1 from here
http://techerrata.com/browse/twrp2/t03g
and i installed it through Odin, and when i tried flashing the rom through TWRP it says successful when i do factory reset and when i try to format data it says failed and when i try to flash the rom it says failed
it keep saying
e:/ unable to find partition size for "/data"
am not developer or expert, but i used to flash many roms for all my past android devices and this is my first time to see such error
well, the device still working when i exit TWRP and do system reboot my rom boot up normally and the device is perfectly working on my phonix 4.3 rom
but i noticed that Odin can not detect my device on the downloading mode anymore but it still can detect it if the device is turned on
So, could you guys advise about what exactly i had missed or damaged here? can i flash other roms? or recovery?
please give me some help here in deep details as am really new to such errors
Thanks a lot in advance and Happy New year for everybody

[Q] ANYONE KNOW GOT TO FIX E:failed to mount /efs (invalid argument)

Ok I have the Galaxy S4 T Mobile Version, I flashed a Kernel that wasn't for the phone accidentally and now im getting this Error E:failed to mount /efs (invalid argument)
Is there anyway of fixing this, Unfortunately i dont have an EFS backup, the phone does work on stock rom, but as soon as i try putting Cynogen Mod on it i get through the install but then im stuck on the boot image.
Ive looked up almost everything on the internet, but cant find anything
Please help me, your my only hope
Try flashing stock Samsung firmware using odin, with a full wipe. That's the good thing about stock, you don't have to install kernels because it always works right.

Yes, ive done that but i dont want to use Stock firmware, and thats why i have a problem, i cant install other ROMS
You flashed stock firmware, is the phone working properly?
Does Wifi, data , Bluetooth work? Can you access stock recovery and download mode?

I guess that would work but if your up and running and you can get into download mode or stock recovery without getting the message about efs and invalid arguments then you should root install a custom recovery and install the ROM of your choice.
If your not getting a message in recovery your done . just pay attention to all details and instructions in op so you don't mess things up.

Cannot mount system/cannot install rom

I just recently got an HTC one m7 that I've fully unlocked, s-off'd, and rooted and now when I try to install a Rom it fails or I should say it hangs on 1% never advancing. Furthest I've gotten is 7% on santod's nusensesixMAX Rom but it wouldn't finish. Is it my recovery? I'm on the latest TWRP. Anyone with any input please
Have you tried the No data Wipe RUU and see if it takes?
No I haven't
I would suggest doing that RUU. it is the one @dottat made where he says it will not wipe SD card that way you do not lose anything on the card. If it is a borked emmc chip and needs fixing, Dottat has some tricks up his sleeve that may work.

Update your twrp recovery to the latest. That is why system won't mount in recovery.

[Help me please] Htc 10 doesnt boot wth custom rom

I apoogize if I asking this in the wrong thread, however I do really need help with my device, I have a Htc 10 S-off with locked bootloader, I already installed twrp, however for some reason every time that I install a custom rom, lets say for example Viper or leedroid, the device gets stuck in bootloop, and I dont really undestand why, everyhting always go well, however the device for some reason its incapable of booting with a custom rom.
Please someone help me :crying::crying:
(Sorry for my bad english)
Did you do full wipe on install? Also it takes Really long time to boot first time on fresh install.
Sent from my HTC 10 using Tapatalk
if you have a backup I suggest using that. if not, then youll have to unlock your boot loader and try re-installing rom, fresh wipe, make sure your also installing the latest stable version and that your model is compatible I'm currently running purefusion OS and I prefer that over stock anyday, easy updates, and bugs are mostly smoothed out now
Thank you so much for answe me, and yes I did full wipe and waited for around 20-25 minutes however for some reason it doesn't boot, and no the phone it's not bricked I flashed the ruu trough the download mode so I have the stock room again, my problem is with the custom roms, for some reason they just don't work with my device

He has S OFF so no need to unlock bootloader as S OFF locked acts the same way

It must be a bad download or something you are doing wrong. Try redownloading ROM and check the md5.
Thank you for answering me, I will try to download the roms again, however I tried different roms and none of them worked, may I ask if anyone knows another reason for this to happen? I will like to try all my options, again thank so much everyone for helping me with my problem and sorry for my bad English.
I just realized something, its not the roms its the twrp that says finished, however actually it hasnt done anything, I tried to flash magisk, super su, and even try to update twrp, and every time says : "finished succesfully" but in reality it didnt flash anything, twrp doesnt work propely with my device is broken, I tried different versions (flashed trough download mode with adb fastboot) and all of them arent working properly with my device, please help me how can I fix this?

I tried with all of them, the unofficial, de latest official twrp and with an older official version (all flashed trough the download mode with adb fastboot) , none of them worked, the worse part is that every time that I flash something trough the recovery it's says that it was successful but unfortunately for me it's a lie, it doesn't do anything xD, I don't even know what to think anymore (lol) this is the first device that does this to me :crying:

I could be wrong but maybe its because its a verizon phone. Im pretty sure theres another forum for verizon. But then again i think people on verizon have used leedroid ROM and in his OP it says its supported. Have you tryed his ROM? Do you get to aroma installer? Make sure your using the latest TWRP and your firmware is up to date aswell. Thats all the help i can give you sorry. Hopefully you can get it sorted.

By any chance did you make sure that TWRP has permission to write to system!? Please excuse me if this has been asked and answered already, but I didn't see such kind of question on a quick glance.

No worries, thank you for trying to help me, about you question, you mean what twrp ask every time you go to recovery? Because I always swipe "to allow modifications" if its that then yes twrp does have permission to write the system.
I believe the encryption is causing bootloop. Try formatting data in TWRP to wipe encryption then install the rom. You will know you are in the right place if you have to type "yes" to proceed.
