Wifi issue is when the firmware is lower than expected.

Once the firmware is lollipop firmware, there should not be a Wifi problem when flash a lollipop custom ROM.

Also note, make a backup of your internal storage files like photos, musics & etc to PC ... some time updating to lollipop you will need to reformat data partition (but this unlikely to happen when doing upgrades from version to version)

[One (M8) Q&A, Help & Troubleshooting] ariebower:
Hi ckpv5,,

I get OTA updates from my device, i already download and install OTA, success installed but bootloop (stuck on HTC logo). Before install OTA, I already backup current ROM via TWRP, after finish backup I flash stock recovery to install OTA. After cannot boot (stuck on HTC Logo), I wipe factory reset and still stuck on HTC Logo.

I restore last backup from TWRP, finally my device can boot again, but when i check software update my phone is up to date but I check my software version on bootloader 4.19.841.7, in About phone software version 4.19.841.5.

It's will affect my device with different firmware like that ?? Later my devices still get OTA update ??

Thanks for help :)
[One (M8) Q&A, Help & Troubleshooting] ckpv5:
Yeah .. it will affect next OTA because the system will still notify you OTA 4.19.841.7 because your current version still 4.19.841.5 even though the bootloader updated to 4.19.841.7

You need to restore 4.19.841.7 backup .. I will see in next few days whether I can upload an updated version for Telstra.

[One (M8) Q&A, Help & Troubleshooting] ckpv5:
Do you have OTA notification ?

You can do this only when you have OTA.

Download OTA, select install later

Connect device to PC

Browse Internal Storage/Download

Copy the OTA.zip to PC

Open the OTA.zip with 7-zip, open firmware.zip and extract out the recovery.img inside the firmware.zip

You can upload to me the OTA.zip, I'll extract the recovery.img for you if you still can't handle this
[One (M8) Q&A, Help & Troubleshooting] Hazem99922:

There isn't much to explain, the RUU is a Windows executable program, and pretty much self explanatory. Just launch the RUU, and it will guide you through the rest.

That sounds very bad mate. Maybe you can uninstall HTC drivers on your system and install them again? Normally windows is picking up your phone and gonna install some files. Sometimes this takes a while. When you have no OS only intalling the OTA doenst work. It's not a full RUU.

When I get into bootloader I can see phone is

software official

S-on

locked

hboot 3.19.0.000

radio 1.29214500021.12g

OS 6.12.161.4

doubt i'm supercid but can be last resort i suppose.

I did put the OTA and renamed 0p6bdiag.zip but same thing happened as a factory reset...

optimising apps 168 etc

then reboots

optimising apps 1

then continual reboot...i'm guessing the bootloader is corrupted somhow...or hardware issue...but im no expert..so yeah

ultimately my other uk m8 connects with win10 and win7 in fastboot usb but this one does not.(using exact same equipment)

it's looking for like for parts :)

EDIT UPDATE: Progress of sorts

I tried changing OTA to 0P6DIAG.zip and also fw_6.12.161.4.zip to 0P6DIAG.zip....resulted in bootloop

messed about on the bootloader. The last thing I remember doing was trying to do a ramdump on to sd card...i think it rebooted again. I tried powering off but missed it.. Anyway i might have rebooted again but it booted into system

I am currently charging the phone on vodafone OS 6.12.161.4 booted into system official but have no idea what this actually means, because I guess i may still be able to boot into bootloader but still not be able to fastboot usb. (rememeber I can get into bootloader and load fastboot, it's just that) fastboot usb is never recognised. Is there anything i can do from system? I think I may need to try root via kingroot and perhaps see if i can install twrp recovery via terminal as I am unsure if phoen will reboot back into system...any pointers?

[One (M8) Q&A, Help & Troubleshooting] wowaneek:
Fixed my phone finally htc__621 - No IMEI

Hi All,

First of all, a big salute to "ckpv5". The only thread I could find in the whole internet to solve the firmware issue I had with HTC M8.

Summary:

I am from Sri Lanka (Asia). My phone is HTC M8, model HTC__621 with S-On. Which is Taiwan (figured out after 2 days of study). Phone did not show Imei number or did not get coverage on sim card. Searched whole of internet to find the solution, tried downloading 6 different roms, flashed it tried it, tried different recoveries etc. Did not have luck. Imei showed on ADB bootloader info, but not on phone. I followed as this thread instruction and got it working at last.

Here are the problems and errors I found while following the instructions in this thread. Then I figured out solutions to overcome it:

Problem 1 - Step 6: I did not see backup folder inside TWRP folder on PC. So I had to manually go to file manager inside TWRP recovery and copy files inside the folder. (if u had this problem, wait, read below for solution on next step for this).

Problem 2 - Step 9: After somehow copying the files and restoring it, after 99% I get restore failed because of some "extract error : 255". Error code was 255.

Solution for above 2 problems: So after hours of figuring out, the solution was to install TWRP 2.8.7.0 recovery as recommended on thread. IF you have 3.0 + TWRP and have any problems, I too recommend to go back and flash older and recommended version of TWRP 2.8.7.0 (which worked well for me). After flashing this, I did the steps again, and restored the files and 2.25GB of restoration completed successfully. Also I could see the folders of TWRP/Backup on PC as well after this.

Let me come to the main problem I had - No Imei number, no coverage (incase if anyone like me wanted to find a solution for not showing Imei or sim card):

Solution

After following all steps in the thread such as flashing TWRP recovery, flashing correct CID backup ROM. Then flash the correct firmware. For me it was HTC__621 firmware of taiwan. Here it had marshmallow version of the firmware, I had a doubt and still flashed the firmware through ADB as instructed, and it successfully flashed the firmware finally. And now all is well, showing IMEI successfully and got coverage + 4g.

So big thanks for ckpv5 for providing all the files and instructions. Cheers! :victory:
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Just a few comments that may clear up what you experience, or help others:

I think you may have skipped Step 5. The sole purpose of that step (for those that have never made a TWRP backup on the device) is to do sort of a "dummy" backup for no other purpose, except to create the required TWRP folder structure, in which to place the downloaded backup.

Backing up boot.img in this case, doesn't server any actual purpose to this process (except to create the folder structure). Its just the easiest partition to pick, as its only a few MB versus over 1 GB for system or data.

Yes, the guide highly recommends 2.8.7 for reason that its very reliable on LP and MM.

I think you may have the sequence mixed up a bit here. AFAIK, flashing firmware results in no OS. So the typical sequence would be to flash firmware,

then

restore the TWRP backup. I'd be surprised if it worked the other way around.
[One (M8) Q&A, Help & Troubleshooting] wowaneek:
Hi,

Thanks for the response.

1st point: I did get a backup, as mentioned on instructions, but still did not see the folders after connecting to PC. I don't know why, but after installing TWRP 2.8.7.0 I could see the folders and all worked well.

2nd point: Yes, 2.8.7.0 worked very well for me!

last point: Yes, Sorry I did not mention the installing rom again part. After flashing firmware, I installed the the rom again and then I got back the IMEI and coverage. Also after this I could install any ROM, so cheers! :)

6(b). For those with no OS, connect device to PC. In TWRP recovery go to mount, make sure MTP is enabled.

Then you can open Internal Storage - TWRP/BACKUPS/SerialNo./ (if backup is set to internal storage)

7. Transfer the extracted x.xx.xxx.x folder (not x.xx.xxx.x_ckpv5 folder) and its content to the backup path on your device, so it looks like this :

TWRP/BACKUPS/SerialNo./x.xx.xxx.x

I went to Mount > Enable MTP

Then my PC recognized it.

I went to the Internal Storage of the phone on my PC, but whenever I go to any folder, It's empty.

I cannot move the img file to Backup because there is no such folder when i browse the TWRP folder on my PC

I'm lost :(
