Those checks are the system checking to see if there is a file to flash on the external SD card. usually used for flashing firmware and sometimes RUU files. It has no bearing on your problem.

Back to kernel stock and unroot for OTA s-on

Hi

I'm root and s-on.

I flashed ElementalX kernel and as I wrote I rooted my phone . now I want to get the new updates ( Marshmallow ) when it arrive but Im not really know how to go back to stock :confused:

How and which kernel should I flash ?

Is this going to delete all my data ?

What is the best way to backup all things (Titanium ? )

What is the full process ?

Thanks a lot !!
[One (M8) Q&A, Help & Troubleshooting] _purple_:
I'm in the same position as you. Root, S-On, ElementalX and of course I want the OTA updates. You should have taken a full backup right after you flashed a custom recovery and before rooting. If you didn't you might be able to find the proper twrp backup for your device in the amazing thread of ckpv5. An update to marshmallow is not recommended without a factory reset. Doing so, very often causes problems. But to answer to your question, I believe it might be possible to update without losing your data by restoring a system backup which is in stock condition and the stock recovery. Then you can proceed with OTA.

Hi. Im using an HTC One M8 international version. I just want to ask. Do people here still use the power saver option of M8?

Because there is an option there which conserves cpu usage. Ive read some threads that it reduces the clock to 1.1ghz tops. Does this function significantly improves battery while screen ON? Because im thinking maybe if for the whole time the m8 is using 2.3ghz it will consume a lot of battery. Correct me if im wrong guys. I just want to make the most out of my phone and also for those people who will be asking the same question.

Thank you very much!

Thanks for the quick replay .

I didn't quit understand . unfortunately I have not take full backup after I flashed the TWRP ,

Can you be more specific about the process ?

Im not familiar with ckpv5 thread ... :(

And what is this part that you wrote : "restoring a system backup which is in stock condition and the stock recovery"

Thanks a lot !! :)
[One (M8) Q&A, Help & Troubleshooting] _purple_:
In order to update Over The Air you need to have the stock recovery. Also the system partition needs to be in a stock state, unaltered, unmodified. Things like root access, custom kernels, Ad block apps, etc modify the system partition. With modified system the OTA fails and the device gets stuck in a bootloop. When you restore the stock boot backup, as far as I know (but I might be wrong) the stock kernel is restored. But custom kernels also make modifications in the system partition that you need to undo in order for the stock kernel to work properly. So you will have to restore the system partition by using a recovery backup of the system. It has to be a clean backup with unmodified system.

Here is the thread I mentioned before:

I use it along with Gsam battery monitor to keep battery consumption down. Every little bit of power helps. I'm not a gamer, so I don't use a lot of battery for graphics etc. I'm more than happy with my battery life, which can be great. To be honest, I haven't looked at the exact figures for a while.
[One (M8) Q&A, Help & Troubleshooting] pnm3049:
Do you still use amplify? Or greenify?

As i can see you are currently using arhd 43.0? Ive been to that rom. Works great. I just switched because it was not updating anymore. Anyway, thats a very good rom. Along with xposed and xtended settings. I just dont know about the elementalx kernel. Ive heard about it a lot of times but what do you with these kernels if you dont overclock or underclock your device.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You're wrong. The CPU cores don't constantly run at 2.3 GHz. The clock speed goes up and down as needed, and as controlled by the governor. 2.3Ghz is just the maximum clock speed.

In theory, yes limiting the max clock speed (underclocking) will save some battery. But it will also make the phone perform slower. You'd probably save a lot more battery by turning down screen brightness and disabling unneeded services.
[One (M8) Q&A, Help & Troubleshooting] Einwod:
I use Greenify. The only reason I have ElementalX is for the fast charge capability. I have it on default settings. I don't need over or underclocking.
[One (M8) Q&A, Help & Troubleshooting] pnm3049:
But using the option of power saver "conserve cpu usage" it somehow limits the cpu to 1.19ghz I think. But it still works with intensive tasks like gaming. Does this contribute a lot to the battery?

[One (M8) Q&A, Help & Troubleshooting] xunholyx:
CPU is always running as long as your device is powered up. It sleeps of course, but it has to be fully dormant. That means no apps running in the background. That never happens.
[One (M8) Q&A, Help & Troubleshooting] Einwod:
Personally I prefer the .exe version. That way I know that everything has been done correctly. One never really knows what files a .zip contain or what may have been added during its creation. The RUU.exe has all necessary files onboard, including recovery. Simply run the RUU and when it's finished, you have your phone back to out of box state. You will of course lose everything stored on the device, so backup all your pictures etc before you start.
[One (M8) Q&A, Help & Troubleshooting] mrrocketdog:
cant you rename the RUU to 0P6BIMG (thats a 0 not an "o") put it on externalSD boot to bootloader and follow the prompts? but as [MENTION=3741261]Einwod[/MENTION] says "you will lose everything". i've done the 0P6BIMG method with RUU , superSU and twrp (credit to [MENTION=4987085]xunholyx[/MENTION] for figuring that out) with success. afterwards make sure you delete the 0P6BIMG or everytime you go to bootloader it will try to run it.

"all i can really do , is stay out of my own way and let the will of heaven be done"
[One (M8) Q&A, Help & Troubleshooting] Einwod:
You can rename the .zip version and place it on the external SD card then run it from bootloader screen, but not a proper .exe file. Try the RUU after this command: fastboot oem rebootRUU
[One (M8) Q&A, Help & Troubleshooting] ckpv5:
To run a RUU .. you need USB2.0 and latest HTC USB driver installed. If not sure, download HTC Sync Manager - http://www.htc.com/us/support/software/htc-sync-manager.aspx

install it as it will install the latest HTC USB driver then uninstall the HTC Sync Manager but leave the driver.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
That doesn't make much sense to me. The very point of limiting CPU clock is to avoid "intensive tasks". What you are saying, is that its limited . . . except when it isn't. So it defeats the purpose.

I'm not too familiar with the specifics of the power save function. But if there are some sophisticated rules on what tasks gets throttled, and what doesn't; it would seem that the "solution" is more complicated (and needlessly so) than the "problem". If you are trying to save battery, you shouldn't be playing games in the first place. Games are one of the fastest way to drain battery.
[One (M8) Q&A, Help & Troubleshooting] Einwod:
When you place the renamed .zip file on the external SD card, remove the device from USB. Go to hboot screen and follow the prompts from there. It will take time to flash, so be patient. The phone may reboot also.
[One (M8) Q&A, Help & Troubleshooting] Einwod:
From what I see, these files are only the smaller update for the stagefright patch. They are not a full RUU. What is it you are trying to achieve here? Are you wanting to go back to a completely stock device and can your device take the necessary RUU? What was your original version of M8 before you went S-OFF? Do you remember the original CID?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
There is no such RUU zip to download, at least not from HTC (you might find one posted by users here). I've never personally done it this way (always by RUU.exe via PC). But from what others have written, once you open the RUU.exe, there will be a file in your PC's temp folder (I believe named ROM.zip). Find that, rename it, and copy it to the phone's internal storage. Reboot bootloader, and the phone will auto detect it and install.

I believe this is essentially the same as the RUU.exe goes in the background. the RUU.exe just gives a GUI to the process.

Installed a 5.1 ROM (rooted) on my HTC One M8 from kitkat (rooted) earlier today, I can boot to Lollipop but I can't access my phone's OS. It's stuck on this download the update screen.

Carrier: ATT

First and foremost I'm updating over cellular, the update is 600~ MB.

I cannot connect to Wi-Fi because I'm unable to access the phone at all until I've downloaded the update.

Secondly I've noticed that at the bottom of the "Download Update" screen it says Via Wi-Fi only until Oct 9.

I'm guessing that there's no way to update until tomorrow, but I was hoping someone had a way to bypass the update information.

I've factory restored as well.

Also, is there anyway to install another ROM via TWRP without being able to go into developer options?...

Stock ATT M8 Stuck in Boot Loop

I am hoping someone can point me in the right direction to attempt to fix my phone. It is a completely stock ATT HTC M8. I have not done anything to unlock it or modify it anyway other than installing standard Google play apps.

Problem: When I took it out of my pocket today, it was on the white boot screen. I have tried to restart/reset it using all of the different power button and volume button holding suggestions I could find. I tried to use recovery mode. I tried to use the factory reset option. The power button/volume button reset turns the phone off, but when it comes back on it is still stuck on the boot screen. All of the other options just cause the phone to reboot and return to the boot screen. I also tried downloading the HTC ROM update from their website and installing it. Its the same version that is currently on the phone 4.28.502.2. The phone just restarts as soon as I start the update and disconnects from the computer causing the update to fail.

Everything else I have seen online talks about using TWRP or other tools, but the guides are geared towards rooted phones and custom ROMs. I have never done any of those things on this phone. I have also never installed TWRP on this phone, so my question is: Is there any way to reload the stock ROM/ reset this phone using the tools described by those guides if my phone is locked, S-ON, stock rom, and no recovery software currently installed? Any other suggestions on how to get my phone out of this loop?

That's because you are trying to flash something not made for Verizon, probably.

Download this.

Rename it to 0P6BIMG.zip and place it onto your extSD

Boot to bootloader and select hboot if it doesn't do that automatically.

Follow the prompts (vol up to flash, power button to reboot)

After it is finished delete the renamed file from your extSD, otherwise every time you boot to hboot it'll try to update again.

Was the device rooted before installing the OTA? Most probably it was or you made some other change in the system partition.

That youtube guy is irresponsible. He has ads enabled to make money from a video that bricks people's devices. Unroot does not always restore the system in a factory state. So the system partition remains modified and the OTA fails. For starters, do you have any pre OTA backup that has a clean system partition?

[One (M8) Q&A, Help & Troubleshooting] _purple_:
You will most certainly need twrp to restore your device and make it boot again. There is one thing for sure. You will lose your data unless you have a very recent backup. Actually it is easy to make your device work again but you need to provide more info if you want help. I asked you if you have a clean backup of your device. But even if you have a backup, you have to know if it is recent. You are not supposed to restore a backup with (quite) old OS version because that might cause problems. If you are not sure then go to the link I provided before. Did you bother to open the link, did you read the first post? If not then please do. And if there is still a problem, maybe seek help there. Because what you need to do to make your device work again is simply use the restore function of twrp. And what you need to do for the OTA update to work is go back to stock with the appropriate backup.
