Remove Red Text from HTC One M8’s HBOOT Screen (Int/Vzw/Spr/Rogers/AT&T/Telus)

 

 

The HTC One M8 is definitely the most beautiful and premium-looking Android smartphone. I has been catching the fancy of users since it launch the last month. As it usually happens, our developer community gather its tools and weapons to come with different hack and mods as soon a significant device is lost. The HTC one M8 is no exception as we already have a plethora of custom development going round the device.

Just a few days ago, we shared a trick to remove the TAMPERED banner from One M8’s bootloader screen. Taking the development further, santod040 from XDA forum has prepared a mod that can remove red text from HTC One M8 HBOOT screen.

While the tampered flag is shown only when you boot the device in Bootloader mode, the red development text scowls at us each time we reboot the phone. The red text message begins to show on all HTC device after unlocking the device bootloader using HTC Dev method and runs like this:

This build is for development purposes only. Do not distribute outside of  HTC without HTC’s written permission. Failure to comply may lead to legal action.

If you want to get rid of this red warning on your shiny HTC One M8 with unlocked bootloader, you can easily do it flashing santod040’s modified HBOOT. The developer has release his HBOOT mod for 8 variants of the HTC One M8, including-

• International HTC One M8 (WWE)


• International HTC One M8 (GER)


• AT&T HTC One M8


• Sprint HTC One M8


• Verizon HTC One M8


• Telus HTC One M8


• Rogers HTC One M8


• HTC One M8 Developer Edition

 

Warning!

You must S-OFF your HTC One M8 before trying the mod since it is all about replacing the original HBOOT with the modded one. In case you device is still S-ON, do not proceed!

How to Reset UNLOCKED Status to LOCKED on HTC One M8

 

 

All HTC phones come with locked bootloaders that needs to be unlocked before involving into any custom development activity. If you got a brand new HTC device with locked bootloader, just press and hold the Volume Down + Power keys to get into the bootloader mode on your phone and you would see *** LOCKED *** banner at the top the screen.

Once you unlock the bootloader of your HTC device via HTC Dev portal or gain S-OFF using Firewater method, the *** LOCKED *** flag disappears and your device status begins to show as *** UNLOCKED *** and *** TAMPERED ***. These flags are deliberately put by HTC to show that you have done something that the OEM does not want its users to do. If there occurs some problem with your phone and you submit it to the service center, your phone is likely to be rejected the HTC guys notice 3 things:

1. Red development text on the bootscreen.


2. And, the *** TAMPERED *** flag.


3. The *** UNLOCKED *** status of the device.

The customary way of regaining the stock *** LOCKED *** status, you will have to unroot your HTC phone and relock the bootloader. Luckily Android is an open source platform and fortunately we have so many talented developers with itching palms who won’t sit calmly at the state of things.

If you own a brand new HTC One M8 with an unlocked bootloader or S-OFF, you can easily get rid of all 3 signs of having a tampered device we mentioned above. Just a few days ago, we covered two hacks to remove the TAMPERED flag and the red development message on the boot screen of the One M8:

Enjoy Louder Speaker & Headphone Volume with Galaxy S5 Volume Boost Mod

 

Personally, I never have had the luck to feel happy about two things on the Android devices I have owned so far: the battery life and the speaker volume output. Being a regular commuter, these two things have always been a matter of concern for me. Nobody likes his/her phone to run out of battery on the mid way, nor does anybody feels good when he/she misses a call or mail notification.

I see Samsung’s latest flagship, the Galaxy S5, as a device that fails to impress the users on many fronts, especially when you compare it to phones like LG G2 and HTC One M8. The volume output of the phone’s speakers is one of the things many of its owners might not feel pleased with. If you own the Samsung Galaxy S5 and are not quite satisfied with the loudness of its built-in speaker volume, we have a good news for you.

XDA member stalli0nUK has prepared a volume boost mod for the Galaxy S5 that significantly increases the speaker volume of the device. His mod is available in three loudness levels: lite, medium and high. Besides, stalli0nUK has also released another mod for those who feel that their Galaxy S5’s headphone volume is not enough loud. Not happy with any of the volume mods? Don’t worry, as there is a restore version too installing which you can return back to stock volume intensity.

All four Galaxy S5 Volume Boost mods are available in recovery flashable Zips. It simply means that to be able to install the mod, you must not only have Galaxy S5 with root access but also a custom recovery like CWM or TWRP installed on it. If your phone meets both these requirements, you can download the desired Volume Boost mod file from below and flash it right away to enjoy louder volume.

Compatibility:

The mod has been tested successfully on the international Galaxy S5 LTE SM-G900F, T-Mobile S5 SM-G900T, Canadian Galaxy S5 G900W8, etc. However, it should work on all Qualcomm models of the Galaxy S5.

Download Galaxy S5 Volume Boost Mod

Warning: Do not try the Loud version of the mod to avoid audio distortion. Go with either version 1, 2 or 4.

Volume Mod Lite: S5_Volume_Boost_Version_v1.zip

Volume Mod Medium: S5_Volume_Boost_Version_v2.zip

Volume Mod Loud: S5_Volume_Boost_Version_v3.zip

Volume Mod Lite Speaker+Headphone: S5_Volume_Boost_Version_v4.zip

Restore Stock Volume: S5_Volume_RESTORE.zip

Link to the latest version: Click here

How to Install:

1. Download the mod file and copy the Zip to your phone.


2. Reboot your Galaxy S5 into CWM/TWRP recovery mode. You do it by turning of the device and then holding the Volume Up+Home+Power buttons together for 4-5 seconds.


3. Do not forget to backup your current ROM before flashing any mod or ROM on your device so that you can restore it in case of a mishap.


4. Use the Install option in the recovery, navigate to the volume mod Zip file and select it.


5. Confirm the installation and wait till it is installed.


6. Finally, reboot your phone using the Reboot system option.

When your Galaxy S5 boots up, you should feel noticeably louder speaker volume on it. Enjoy and do not forget to share your feedback with us!
