Kernel question - Verizon HTC One (M8)

I recently had to get a replacement phone sent to me from verizon. I'm on 4.4.4 I bought and used sunshine for unlock and s-off. I have flashed twrp and super su for root. I have not touched the kernel so I am still on stock kernel which has write protection. There are kernels out that have this disabled. What I'm trying to find information on is how do I flash one of these. I can't seem to find info on this. I got the original m8 on launch day and have done this months ago and I remember having to put certain things on the SD card and renaming them to something along the lines of (0BP6.img).
Is this correct. I also remember having to adb certain things to the phone. I'm just trying to avoid a brick. Any help is appreciated

So I should just be able to download a sense 4.4.4 kernel and flash in recovery then I can nandroid backup and then start flashing custom roms? I just didn't know if I was able to flash one in recovery coming from stock which is write protected without problems.

have you tried to flash a ROM already? Cause I have been with HTC sense way way back. An I never have had this issue...I just pick a stock ROM an flash it... But you could fast boot a stock insecure boot using fast boot I guess if that's what you want to do.

I haven't tried to flash a stock rom no because I wasn't sure. And I don't want to wipe system and data with a write protected kernel because I'll be screwed. Or do you mean dirty flash a stock rom with the insecure kernel? I just don't want to not have write protection removed and then wipe and soft brick because I can't write to the system with a new rom

If you r s-off unlocked an flashed twrp then flashed SuperSU zip. Myself I just back a backup now verify backup is there an flash a ROM...or you could flash a stock insecure kernel 1st if you want to be extra safe.

Thing is I bricked my last m8 because I flashed a stock recovery and rom to get the 4.4.4 update. And I wiped system and data to re install a rom and couldn't write to system and the phone wouldn't do anything but sit at the HTC screen because it was bricked. That's why I'm concerned with the kernel.

You should be able to just flash pretty much any sense based rom and have what you want. Write protection is removed in all of them, or, at least in all the ones I've tried.
That said, if you've already flashed a kernel that has write protection removed, you should be able to check it by just copying any file to the system folder. A text file, picture, anything. Then reboot the phone and check to see if the file you copied to the system folder is still there. If so, you're good to go. If not, write protection is still being enforced.

[Q] JB update and custom kernel

Hi all,
I'm sorry about my stupid question but I really don't know nothing about that . I had rooted and flashed my NS and installed the matr1x kernel (very good btw), and now I knew that JB will be available to NS. My question is, need I back to stock kernel to receive the update?
Thanks

You have to understand that installing an OTA (official update) on a rooted device regardless of what kernel can cause problems, as it did with my Nexus S before. I suggest you make a NANDroid backup at all times before you install any ROMs, official or Custom. You can also use Titanium backup and others.
There's still a slight while until the new JB 4.1 comes out. It's suggested that you install a Custom JB 4.1 ROM for your Nexus S as though you don't cause any problems. I think it's OK if you do it with the kernel pre-installed. But people always install the Custom ROM THEN they install the Kernel, I think installing a new ROM always overwrites the kernel, if it comes with it.
EDIT:
In short, wait for the JB Custom ROM and you don't have to revert back to stock kernel, when you do the update it will automatically overwrite. Most Custom ROMs come with Stock/ordinary kernels. So then the user can flash whatever kernel they like in your case, matr1x.
Wish you the best of luck, and I am waiting for the Nexus S JB to come out as soon as possible
Ota binary patches the boot image iirc. So it can get all messed up.

A NANDroid backup is a internal memory backup. You can create one by booting into Recovery (Power off your phone and Hold Power and Down on your volume buttons.) If you rooted your phone and unlocked your bootloader (that's what you had to do to flash a new kernel), you should be able to load ClockworkMod or TeamWin Recovery and do a backup of your phone.

There's one rom but it's a port from the SDK and the amount of major bugs is high so it's not recommended but you could try another custom rom meanwhile, I can't go back to stock after trying custom roms, like AOKP and Cyanogenmod 9. Make sure you backup your apps and some settings (not everything will be compatible between stock and custom so pay close attention to which system setting you'll backup) with Titanium Backup.
To sum it all up for you
There's a Jelly Bean release which is unstable and has no sound, and will not be fixed until the REAL version comes out.
NANDroid backs up the whole internal memory on the phone including the system, it can be done from clockworkmod recovery.
Titanium backup, backs up specific settings and information that you choose, available from the playstore.
You don't need to unroot or go back to a STOCK kernel in order to flash a CUSTOM ROM. DO not however flash a STOCK rom after rooting, as at times that can cause problems.
If you want to go back to a STOCK ROM after rooting a device, there's a way, check this guide
http://forum.xda-developers.com/showthread.php?t=1063664
and choose your Nexus S model: To acquire model, go to Settings - About - Baseband version. if it says I9023 at the start that's your Nexus S's model
Choose one of the Fastboot Stock ROMs and use the Fastboot method to flash the ROM. That is a good way to go back to STOCK ROM if anything bad happens
By the way you should expect the new OTA official 4.1 update for the Nexus S to be on your model's page.
NOTE: Using Fastboot to flash a ROM is very clean. However this will delete all your data and if you do everything correctly will lock your bootloader and unroot your phone. So use Fastboot only when you really feel the need to.
Cheers
and stay tuned for Jelly Bean :victory:

That means, when I receive the official 4.1 update notification, I should unroot my phone first and just install it after?

OK first off, do not install the update using the system update method from about, as that is a 100% stuff up if you're still rooted or on a Custom ROM.
However to update I think flashing a stock ROM but USING Clockworkmod works fine!
Someone please confirm, as I am not 100% sure
However what I am sure about is that if you run into any troubles installing your STOCK ROM using Fastboot is very very good and clean, however there are 2 things:
1. You will wipe everything COMPLETELY
2. You need the ROM to be in a fastboot format kind of way for you to flash it
There's a guide and everything for fastboot.
---------- Post added at 12:35 AM ---------- Previous post was at 12:33 AM ----------
Personally I will wait for a custom ROM for 4.1 if it doesn't take too long as that's guaranteed and will obviously be faster and safer to install on a ROOTED device.
Someone still confirm if installing Stock ROM while over Custom ROM while ROOTED through CWM is OK or not!?
Hummm, ok...
I'm already using the Stock ROM, I just flashed a new kernel, and I prefer install the stock kernel and unroot my phone. Just to let it clean.
After I install the JB official update, maybe I flash and root again, depends of Google :laugh:
Do you know where can I download a trust official 4.0.4 kernel from the forums? My phone is a Nexus S I9020AUCKJ1, Version Number: IMM76D
Thanks!!!

Rooting Nexus S [Help]

A while back, I always rooted and unrooted my Nexus S with no problems at all. Now whenever I try to root it, it just goes wrong. I've tried TWRP & CWM, CWM used to always work but now it just messes up. Both TWRP and CWM both give me an error that say Installation Aborted when I try to install a custom rom. I've redownloaded the rom from different browsers and even different PCs but nothing working, still that same error. Does anyone have a guide that is 100% to work without any errors during the process?
What guide are you using?

1. Make sure you're running one the more recent versions of the custom recovery. You probably are but there are issues with older versions so just make sure.
2. Boot into what ever recovery you pick and do a full wipe. That is everything gets wiped but your SD card. Factory reset. Format /system etc.
3. Flash your ROM and gapps if they are seperate.
You should not get any errors. If your recovery is current and your flashing a new rom onto a fully wiped system and you still get a error either you're screwing something up or you may have a hardware problem.
To rule out a hw problem flash the factory images with fastboot. If those flash normally and everything works it is almost certainly user error.

Alright, thanks Do you recommend that I root my Nexus S or should I wait for the Jelly Bean update? I've rooted before and I enjoyed it but now I don't see that many reasons to root, do you have any good reasons?
I have many. My reasons for root don't matter. If you don't have a reason for root then don't root. Its that simple really.
Make sure you're on a stock 4.0.4 rom. When the ota is out install it.
If you want just root on either os at any time just flash su.zip from custom recovery. Its that simple. Having root on a stock rom does not affect the ota process.

What are your reasons for root? Please share?
Getting rid of stuff I don't want in a ROM.
Apps that do things that require root.Titanium backup/autoruns adaway ( ad blocker app alone could be its one point) etc
Changing kernel settings. Bid/bin clocks volts etc.
Being able to have a replacement launcher use the ICS style widget drawer.
Lastly , I simply just can't see having a computer that I don't have root/admin rights to. Its my damn device and I do what I want.

Oh cool. There is this project that some members from XDA are working on called Sense4All and they are porting Sense to many devices. Im probably going to wait until a fully functionable release is available for the Nexus S. I do like AOKP a lot, so that might be a reason for why I'll root.
You seem to be a little confused with some terms. Root is simply being able to grant superuser permission.
You don't need to root to flash a custom rom on a nexus. Just a unblocked bootloader. You could run aokp or any other rom without root if you wanted to.

Oh, I never knew that, haha. Is it possible to flash a custom kernel with an unlocked bootloader or does that require root access?

No you just need a custom recovery. But using that kernel's mods, like BLN, OC, UV, touchwake, etc, requires apps that need root, like NSTools, SetCPU, etc.

What methode did you use to unlock it? I'm running the stock no nonsense rom and I belive unlocked with no problems
Do other roms boot? Will the newest CM10 nightly boot? Will anything boot?
Did you flash a different recovery? If you were using kexec roms before (beans is one, so is synergy with imo's kernel) and then flashed a non-kexec-supporting recovery, that'd explain not being able to boot. If you're unlocked, you don't have to flash a new recovery.
If you did the unlock correctly, you should be able to boot whatever you were able to before. If you can't get anything at all to boot, it's possible you flashed a bad aboot image.

Yep, that's exactly the problem. You installed a non-kexec recovery and your roms still use kexec.
You're sure you selected the right options in EZ recovery? Open it, scroll to the recovery pane, select the "recovery" radio button, change the drop down menu next to it to CWM 6.0.1.0, click the "Flash!" button. That should let you install whatever roms or kernels you like.

Being unlocked shouldn't have any impact on being able to flash using ez-recovery. One thing you can try is use EZ-Recovery to flash stock recovery, odin back to the stock verizon image which should relock the bootloader and start all over.

Why do you need to flash stock recovery to use Odin to flash stock Verizon rom? Odin has nothing to do with what recovery you have installed. I flashed stock unrooted rom while rooted and having CWM recovery, it worked just fine. Once you flash stock rom, it restores the stock recovery too anyway. I'm fairly sure of this, but if I'm wrong, please correct me anybody.

Just to be safe. Wanted to get rid of the sprint related elements from the original root so I Odin'd back to stock with cwm installed using the VRALF2 tar found here. Tried to boot into recovery to factory reset prior to first boot and had 0 recovery (not stock nor cwm). Luckily the rom booted and I used the simple root method to root and install EZ-Recovery to install CWM.
If I flashed synergy v1.7 and used rom manager v5.x.x and then unlocked the boot loader how would I flash a new rom? Do I have to use ez recovery with clockwork mod v6.x.x since it is now unlocked or can I continue using rom manager with clockwork mod 5.x.x. I'm a noob and won't be looking to switch roms until synergy gets jellybean. Thanks for the help and hopefully I made sense with my question
synergy to beans to synergy bootloop
I think my issue might be related to the issues stated above.
So after after having unlocked my bootloader with EZ unlock & installing beans custom Rom via TWRP , I decided to go back to synergy. I made a nandroid of my synergy which was origianlly installed with CWM and figured I could just wipe and restore that with TWRP. Total bootloop.
OK, so I pulled the battery, tried it again...bootloop.
SO I pulled the battery, wiped and installed the synergy zip thinking I could try a fresh install. I got a message in TWRP that E:sd-ext was not found, but wipe seemed to happen so I continued the process.
installation said it was successful but now when I try to boot up, I either get stuck in the android is upgrading applications (looping over and over) or it gets through there and tells me all teh com.android.xxxx applications unexpectedly stop.
is this a soft brick? can I recover from this? are there incompatibilities between the kernels of bean's custom rom and synergy for verizon samsung galaxy s3?

Viper XL and boot.img

Hey guys I just wanna to check and make sure I'm doing everything right before I flash cause I don't need anymore paperweights
1.I have successfully unlocked my bootloader and installed twrp recovery and rooted.
2. Now I want to back up my entire setup: rom, apps, setting, data, everything so that if I ever want to return to stock then I can. I have booted into twrp and ran backup and selected all options. Is that how you perform a nandroid backup in twrp or is there more to it?
3. I want to install team venom viper xl rom. Do I have to first flash boot.img first or is the kernel the same in stock and viper xl so that isn't necessary? Do I have to do I factory reset first or what?
I'm still new to this stuff so please bear with me. Thank for all your help!!

Different kernel. it is using the 2.41 RUU. So go ahead and flash the boot.img
Here's what you should do for any new ROM with a different kernel.
Wipe System
Factory Reset
Flash boot.img
Flash the ROM
flash gapps (if AOSP based)
reboot and have fun
When doing a nandroid backup, it is only necessary to backup
System
Data
Boot
Ok thanks for your response but I'm still a little confused. First did I back up my current rom properly so that I can return to it later on? Secondly does viper and boot img have to be flashed or can they be installed from sdcard via twrp? If they have to be flashed whats the fastboot command.?

You backed up fine, it just takes up a little more space.
You have to extract the boot.img from the ROM and put it in the same folder as fastboot.exe
open command prompt, and navigate to the folder fasboot.exe is in and do the following command
fasboot flash boot boot.img
If it gets stuck at waiting for device, reboot into your bootloader, boot into fastboot from there. and then try again.

Ok thanks for your response but I'm still a little confused. First did I back up my current rom properly so that I can return to it later on? Secondly does viper and boot img have to be flashed or can they be installed from sdcard via twrp? If they have to be flashed whats the fastboot command.?

Viper is the Rom u flash it from twrp it's. azip file that's fkashable so make it easy and flash viper there and than flash the boot IMG from fastboot the command is all over the forums I thinks it fastnoot flash boot.img
don't be confused. read.
you always have to flash boot.img in fastboot "fastboot flash boot boot.img" then flash the zip in twrp make sure to wipe, and don't download international roms. you still have to flash the boot.img from your backed up rom.
like a hundred threads asking the same stuff because no one wants to read

I'm sorry but I did read. I saw that if you have the same kernel as that of the rom you're flashing you don't have to flash boot.img. So I asked to see if stock and viper have the same kernel. I don't want to flash anything that will brick my phone.
Now one more question if you don't mind answering. I also saw that you can't downgrade RUU. So if viper is based on 2.41 RUU and stock is 2.20 RUU then will I be able to go stock after flashing viper?
I really do appreciate yalls help. i would be where I am if it weren't for you.

Yes. Just wipe you system and do a factory reset , and flash the boot.IMG for 2.20 and then flash the Rom.
If you want true stock 2.20 then you will have to relock your bootloader and then run the 2.20 RUU. You would only want to do this if making a warranty claim or something. If you want stock rooted, then yes, do what I said above

Ok got it. I do appreciate your help. Flashing now.
downgrading only refers to the ruu not the zipped roms. so you can't run 1.85 ruu after running 2.20 ruu/ota but you can still flash a rom based on 1.85.
if you are reflashing the same rom you don't have to reflash boot.img but if you are flashing a new rom then you need to flash boot.img. 7-zip will tell you the crc32 of files so you see tell if it's a different checksum.
Viper Xl's great. Seems to be slightly slower than stock on some task, but the lack of bloatware, and the extensive customization is worth it. Haven't found any bugs or nothing so far. If anyones familiar with viperxl though what is the last app in the app drawer? Its got a chinese name? When it loads it says Dolby Surround but all the writing is in chinese?

That's because you flashed the Voodoo mod, it's apart of the mod, theres a chinese part and a english one called "Dolby Digital" or "Dolby Surround"
When I flash ViperXL 3.1.0 JB do I need to flash a radio too? My phone has hboot 1.4 and software 2.2, so I understand that I cant flash radio with hboot 1.4? Does this mean I need to downgrade my hboot/software version?

Hmm. Might there be a patch I'm missing out on? I just flashed one file -ViperXL 3.1.0 JB - Android File Host (692MB)
edit- Works now after another reinstall installed boot image first this time.

[Q] Changing Stock kernels

Hi,
I have managed to put on a kernel that's not working. Is there a way to revert back to the original kernel? I do have a nandroid backup, but re-installing that didn't put on the old kernel.
I am using Liquidsmooth ROM. Any help would be appreciated.
Thanks.
if you can boot into the rom use flashimagegui, if not do the normal fastboot the boot.img then do it again with flashimagegui to get the modules.
what kernel did you try to flash? the only kernel that will work with new liquidsmooth is cm10.1_vz-oc-linaro.3.zip. it contains modules, if you aren't s-off then you need to flash boot.img in fastboot then flash again in recovery for the modules.

I did exactly that, presuming that it was working... But I have been facing issues. The phone restarts every once in a while and I have managed to get to this condition after multiple wipes and restoring a backup. Anyways I don't know what the issue is I was just wondering how to revert back to the original kernel.
im running Liquid-JB-v2.1-RC2-evita.zip and cm10.1_vz-oc-linaro.3.zip. there seem to be some general issues with the rom that present as basically glitching and gets worse overtime atleast for me. im pretty sure it isnt related to the kernel. but to revert kernel just load the liquidsmooth zip into flashimagegui and itll pull the needed files, let it wipe cache and dalvik then reboot.

yes, Flash Image GUI
you should also s-off your phone it will make life ALOT easier and the process is simple take like 2 minutes.

Thanks I'll make sure I do that..
also new stable build of liquidsmooth just got released. you should flash it. imma flash it with a clean full wipe. but you should s-off first so you dont have to flash boot.img separately every rom.

Ya, I saw the new version wanted to try that which is why I wanted to got to the old kernel version. I had tried installing it with the linaro kernel but it gets stuck on the boot screen.
Update: - I installed the flash gui image, then extracted and installed the kernel , factory reset the phone, then installed the latest liquid smooth build. But it is still not going ahead of the boot animation.
Update 3 :- Got the old kernel back. Did a restore. Working fine now . But still for some reason I cannot install the new ROM yet.

you need everything. you don't need to extract the kernel. just load the whole zip file.

I did load the full file and the flash gui image extracted the kernel. The thing is I have the kernel now, but still I can't seem to be able to install the new version of the LiquidSmooth build. I am doing a nandroid backup of this thing and try installing it again.
well new liquidsmooth is nice, im using cwm now as recovery since ive had tons of issues with twrp since version 2.2.2.0
