[One (M8) Q&A, Help & Troubleshooting] DrWu:
New day, new problem.

I have an M8 (Vzw) on LOS 14.1 that I'm using on Page Plus Cellular, an MVNO of Verizon. I only noticed a couple of days ago that cellular data is very sporadic, more off than on. I searched for people with similar problems and naturally none of them matched my exact circumstance but I did try bits and pieces of their solutions. A lot of what I have tried got cellular data working briefly but all of them fail again in seconds to minutes. Mostly I tried swapping about the settings under "Cellular networks."

Before resorting to asking for help here, I did a factory reset, and it worked, but only for a while. I didn't spend too much time working with it in bare-bones condition before beginning adding apps and configurating (if that isn't a word, it should be) but I stayed away from anything cellular-data related. For instance I didn't change the phone app or the contacts app. But before I even finished side-loading my apps (through adb), I was losing cellular data connectivity.

So I am spent. Shot my wad. Outta bullets.

Figuring anyone who might have an idea how to correct this might also have need of what settings I have available in my particular phone, so here's what I'm looking at. These are all the selections that I thought might be pertinent. If I've missed any you need, please ask.

Under 'Cellular Networks'> 'Preferred network type', the choices are:

Global

LTE/CDMA

LTE/GSM/UMTS

The default setting was 'Global.'

Under 'CDMA subscription' the choices are:

RUIM/SIM

NV

The default was RUIM/SIM.

Under 'Access Point Names',

StraightTalk Verizon [TRACFONE.VZWENTP]

Verizon [VZWADMIN]

Verizon [VZWAPP]

Verizon [VZWIMS]

Verizon [VZWINTERNET]

None were selected by default. Oddly there are two sections for APNs, both offer the same identical and a change to one also changes the other.

That's all that are under 'Cellular networks' but I found other fiddly bits in the "Phone info" service menu code (*#*#4636#*#*). I have all the options under 'Set Preferred Network Type':

WCDMA only

GSM only

WCDMA only

GSM only (PRL)

CDMA only (PRL)

CDMA only

EvDo only

Global auto (PRL)

LTE/CDMA auto (PRL)

LTE/UMTS auto (PRL)

LTE/CDMA/UMTS auto (PRL)

LTE only

LTE/WCMDA

TD-SCDMA only

TD-SCDMA/WCDMA

LTE/TD-SCDMA

TD-SCDMA/GSM

TD-SCDMA/UMTS

LTE/TD-SCDMA/UMTS

Global/TD-SCDMA

Unknown

The default is LTE/CDMA/UMTS/auto (PRL)

And while I have the 'Phone info' window open, 'Data Service' reads: Disconnected

I don't even want to think about how many permutations that makes but it's too many to sort through by hand, so I'm hoping somone here has a better idea than I do how to proceed.

HTC one M8 not flashing

Hello,

I have tried to root HTC One M8 (European Edition) ( CID-032) with one in all tootlkit but somehow can't root it properly. Then decided to get back to stock rom and unroot it. But while flashing the stock rom I got error 12 signature verification failed. Tried to flash by unlocking bootloader again but failed and got message 32 header zip error. From thread tried CWM and TWRP recovery but can't install any RUU.zip. Got message that zip is corrupted. Tried couple of zips matching CID but all shows corrupted. Tried ADB Sideload also but got error message there. Is the phone completely dead? Is there any solution?

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You're doing this all wrong. Seems like a huge lack of understanding and research regarding the right steps for this device.

1) Do

NOT

use the toolkit to root. It is very outdated, and contains all the wrong files (TWRP, SuperSU) for any but the oldest configuration M8 versions (which the huge majority do not meet that definition).

2)

Before

trying to root, you should have made a backup of the stock ROM. That way, once the root attempt failed, you could have just restored the stock ROM.

3) Using the correct version TWRP and SuperSU (or recommended Magisk instead) to root may fix the problem, without having to restore the stock ROM. The correct versions will depend on your current firmware version. Tell us what OS number is says on the bootloader screen, or alternately, the radio number. The OS number will most likely be blank (known bug with old/obsolete TWRP versions).

4) You can just run "any" RUU. It has to match the CID and version number (cannot flash older versions than firmware installed on the device) for your device. That is the reason for header error.

5) You can't run RUU.zip with TWRP or CWM. The RUU is encrypted (and does not have the ability to decrypt it), and that is why TWRP is saying it is corrupt. It will only flash with htc_fastboot or alternately with SD card method.

6) You must relock the bootloader to flash RUU (reason for signature error). But I would suggest trying bullet #3 above first, since that is what you were trying to do in the first place.

7) CWM never officially supported this device. The only "working" CWM builds for the M8 were unofficial ports. All are extremely old and obsolete, and will not work on my M8 versions (maybe only Kitkat firmware?). I don't recommend using any CMW for the M8. Stick to TWRP, which is known good.

---------- Post added at 09:36 AM ---------- Previous post was at 09:32 AM ----------

This is one way for the user to get back to stock. However, they will probably need to update TWRP version, as the TWRP version flashed by the toolkit is no longer compatible with most firmware configurations.

Also, the user will probably not be able to tell what OS (firmware) version is currently installed on the device. Since the obsolete TWRP version will cause OS number to show as blank on the bootloader screen, and getvar.

User should tell us what radio number is shown on the bootloader screen; so we can advise further. Or better yet, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

first OS was 6.12.401.4 and then I install TWRP 3.2.3.0 and flashed a rom through sd card and got back to stock rom but unfortunately OS got blanked and can't lock bootloader now. But anyway thanks.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Need more details, if you want some meaningful help:

- What ROM exactly did you flash? How did you flash it?

- Are you trying to lock bootloader to flash RUU? How did you try to lock it (exact commands, error messages or other outputs, etc.).

- It's unclear what you are trying to do exactly (based on the above quote). If you returned to stock ROM, why lock the bootloader?

How do I change the font in Settings app?

Dear good fellows,

I've been a flash maniac for some time but I always reverted back to Sense based ROM due to my age weakened eyes no matter how good AOSP /AOKP/AICP based ROM's are.

My question is simple:

How to change the font in the Settings app to resemble like the attached. It is a screen shot from my Sense based ROM.

I want other non Sense based ROM to have that exact size and style, especially for the Settings app. AOSP has been a torment to my eyes.

I've tried many font apps in store but to my dismay I haven't found it to suit my needs. Is there any tweak that I could employ be it configuration text files, xposed or magisk modules or anything? I'm rooted.

Thanks and have a great day.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Not sure why you are responding to a post from January 2016.

In any case, s-off does not prevent updates.

But the only way this device would get updates at this point, is if it was still on a really old version (like Lollipop or earlier) and returned to that same stock.
[One (M8) Q&A, Help & Troubleshooting] DrWu:
I bought an HTC One M8 specifically to load LineageOS on, and I love the phone and the OS but the phone speaker is too weak (and so are my ears). Because of the low volume, in best of cases I strain to understand and when I'm talking to a younger person (so many of whom use the speaker phone by default) I feel like I'm talking to Charlie Brown's school teacher.

I bought a JLab (corded) ear bud thinking that might ameliorate the problem but if anything it's slightly worse. I don't do BlueTooth ear buds any more because they got too expensive (I kept leaving them in my shirt pocket and washing them).

I know about ZeroInfinity's IntenseBLAST speaker volume enhancer, and I wasn't as much put off by the fact that it's unmaintained (it is a 4-year old phone, after all) but I couldn't find a copy of the file. All the links appear to be dead. Plus I'm not clear on whether it will even work on the LineageOS ROM.

Anybody know how I can get a skosh more volume out of my M8?

If it matters, I'm running LineageOS 14.1.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You might search around the M8 forum, if anyone has modded the mixer paths xml file to increase call volume. This is a pretty common way to increase call volume on other Android devices. Although I'm not sure how exactly to implement this on the M8/Lineage, or whether or not it is confirmed to work for this specific device.

I hear you there! I've sent one Bluetooth earpiece through the wash, and lost 2 others. But still using them, I still find them the best solution for all the work conference calls I have.

I recently switched from crDroid to Xenon. One feature that I miss is when the phone was connected to a power source, a small red light visible in the top speaker grill lit up, and it turned green when fully charged.

Is that a feature of the ROM or the kernel? If it's a feature of the kernel, since both roms are Android 8.1, is it risky (in terms of the likelihood of bricking) to install the crDroid kernel on top of the Xenon kernel?

Thanks in advance for any/all replies.

People, currently I am running a 4.4 version modified stock rom on my m8, and I want to upgrade to 6.0. Also, I have SuperCID(I don't know what my original CID was) with S-OFF and Unlocked Bootloader. Since my current rom is modified I can't install the OTA that I am receiving, so I want to know what should I do to upgrade my phone? Should I do a nandroid backup restore and then apply the updates? Or should l directly flash through the RUU method?

Can you clear me up on TWO things?

One, I would like to know if it is safe to take OTA with SuperCID?

Second, Do I need to upgrade the "firmware" of my phone to MM (as currently, I am running KitKat) and then flash the MM RUU on my phone? Or does the RUU upgrade the firmware by itself?
[One (M8) Q&A, Help & Troubleshooting] Einwod:
Of course it's safe, but you must be stock and not rooted. If you have root, the update will not install. Go to the version of the stock ROM that you wish and then update as normal. Once updated, you can re root again.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Either method is fine; with differences noted:

Stock nandroid method will be more steps. In fact, after you have restored the 4.4 stock nandroid, you will need to do multiple OTA updates to get to 6.0. Otherwise, flash the MM firmware and then restore MM stock nandroid.

RUU will wipe data, so you will need to prepare accordingly. But honestly, with such a big update; I would plan to backup all your data, anyway, just in case.

This is assuming your version has an RUU. You realize the RUUs are CID/MID specific? Even though you are SuperCID, you will still want to us the correct RUU for your MID and current firmware version number.

---------- Post added at 02:22 PM ---------- Previous post was at 02:18 PM ----------

Mostly, only US variants need to flash MM firmware before flashing MM RUU. Specific to MM RUU (updating from older Android versions) and again, only applies to US carrier M8 versions. For other carrier versions, as long as an RUU is available, you should just be able to flash it (without flashing firmware first).

You haven't stated what M8 version you have (or any other specific info about your device. So I don't know if the above caveat applies to you, or not. For the best info, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

---------- Post added at 02:35 PM ---------- Previous post was at 02:22 PM ----------

I don't know much about those specific ROMs; or whether the kernels are interchangeable (or for that matter, if this will have any effect on the charge LED). Just a

guess

, since they are both 8.1 AOSP ROMs, they kernels

may

be interchangeable.

But what I can say, is that you will not brick from flashing a kernel. Even if the phone doesn't boot to OS after flashing the crDroid kernel (probably the worst case), just reboot to recovery, and reflash the Xenon kernel. Or even dirty flash the whole Xenon ROM.

Make a backup in TWRP of your current Xenon ROM, including boot.img (which is the kernel) before flashing a new kernel.

Hi, new member, basic skills! I have an HTC one M8, which has been stuck on second boot screen (where the one scrolls on) won't turn off, I have to force restart. I finally got the timing right to turn on with fastboot menu.

When the screen goes to the "Red Triangle", you have to press both, the power and the increasing volume button, simultaneously to go to the recovery.

Can anybody tell me if it is safe to flash a "Signed RUU; One that is not decrypted " on an unlocked bootloader ?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You can bring up the stock recovery options with the button combo mentioned in the last response. But all you can do there, is factory reset, or wipe cache. Those might help, and certainly worth trying (obviously, if you factory reset, you will lose your personal data). But it's more possible that some portion of the OS has become corrupt/damaged, and restoring by means or RUU or other method is required.

---------- Post added at 12:57 PM ---------- Previous post was at 12:56 PM ----------

RUU will fail to install with unlocked bootloader, by definition. The exception, is if you have s-off.

I have S - Off & an Unlocked Bootloader, so I can flash a "Signed RUU" ? The CID AND MID match with the RUU.

Also, my HTC One M8 got updates (OTA) to Lollipop and after that it has stopped receiving updates. I receive the message that my phone is up to date, although I know there is a Marshmallow update available.

- What do you think the reason could be? Its an European Model btw.

- I don't want to wipe the internal storage of the phone, and I want to to update the phone as well. How should I go about updating the phone?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Yes, you can flash a signed RUU (that matched devic CID/MID) with unlocked bootloader and s-off.

Same as with s-on. The only difference is that s-off bypasses the requirement to relock the bootloader.

I believe a signed RUU will wipe the phone, regardless of whether the bootloader is locked or not (if keeping data is what you were hoping for).

Since you want to keep data, then a modified "No Wipe" RUU is probably what you want: https://xdaforums.com/htc-one-m8/development/progress-fuu-m8-t2813792

Another method: Since you have s-off, if you can find the correct OTA file for your CID, you can put it on the phone and update it what way.

But honestly, for any major update, I always backup my personal data just in case. Never assume your data will survive an update. By that point (backed up your data), then a full wipe (such as by RUU) and restoring your data, isn't that much more work (although that may depend on your specific configuration). And makes for a much cleaner install.

Hey Guys,

I was on ARHD 53.1, it was functioning normally, until last time use, that rom got very slow and I selected "Restart" button in power menu in order to get a fresh boot again and to fasten apps like before (I thought that slow speed of rom was due to some software issues or something),,, after that guess what? not only can I load the ARHD rom, but also I can't boot into TWRP !!!

My phone is shutted down, it doesn't respond to power button pressing. after about a min to turns on in respond to power button pressed, and it enters FASTBOOT. after changing to HBOOT menu and selecting RECOVERY, it doesn't enter twrp recovery at all, just 3 android icons beside each other appear and after that it enters FASTBOOT again.

and when it is shutted down when plugged into charger, it starts with battery icon with lightning within it (but without any red written lines at bottom or HTC logo) and then it boots into FASTBOOT AC menu again!

As it doesn't show any HTC logo, I presume that my device is broken.

in FASTBOOT menu it shows "INVALID_VER_INFO" in-front of RADIO and OpenDSP.

my m8 doesn't boot android ROM (ARHD 53.1), it doesn't boot TWRP recovery neither.
