htc desire 820 network carrier unavailable - Desire 820 Q&A, Help & Troubleshooting

Please I need help, I don't know much about this.
My SIM works on other phones but not in this HTC. I researched and found out I have to go through fastboot and boot loader processes to unlock SIM but the phone won't enter fastboot (the white background with red,yellow highlighting options). All it does with vol down + power is "android system recovery" (with a dead android icon).
Please I need a walk through on getting my SIM to work please anyone, I'm a novice in this.
Phone is not rooted too.
Thanks a lot.

this means that your device is sim unlocked .. no need to use the code
you only use it if you insert a sim from another company and THEN it will ask you for the code

this when the code comes in handy , you should enter the code then.
where did you get this code from ?
i am not sure about this .but. if you tried unlocking it with any other software like lokiwiz then "maybe" you should hard reset your device before trying again .

I never said tap on the emergency . you are going to get yourself into trouble man .. really calling 911 to unlock your device ..
the steps are
1- turn off device .
2- put "another" sim from "another" compay"
3- turn on the device
4- enter you unlock code in the "TEXT box" -i missed the t before the ext sorry-
5-press ok
if the code is not right you will get an "invalid code " message
where did you get your code from ?
Thank you for your big help
sorry to bother you. probably I'm getting yourself into trouble...
I got a code from tupisdin, then,
I enter the code into text box for emergency number,
but OK was not appeared, just emergecy button is dimmed.
Just in case, write under what I did.
1- turn off device .
2- put "another" sim from "another" compay"
3- turn on the device (of course, I'm sure that it is not fright mode)
4- wait for a while, then it was displaied TEXT box under "SIM Lock, You can still make emergency calls if your service..."
5- enter unlock unlock code in the "TEXT box"
6- keep to dim "Emergency" button...
I probably mistook right?

[Q] Forgot Pattern Lock

Hi there,
I owned a Galaxy Nexus running Jelly Bean 4.2.1 version, yakjuxw (Not rooted), GSM. I activated the Pattern Lock to prevent the kids at my relatives house messing my phone. Unfortunately, I forgot the pattern and the phone stays locked out. I have tried the pattern combinations for days but failed.
I have tried to key in my Gmail account username/password but since my phone is wifi/data switched off, I cant sign in. Moreover, I am not sure whether the USB Debugging is enabled.
I have tried some 'hole' methods recommended at some forums, but it didnt work on my phone.I hope to get access to my messages/images/some files and transfer them to my pc before reset the phone to factory setting. Please help! :-|

You can reset the phone to Factory settings.
1. Turn off your phone.
2. Press vol up+vol down+power buttons till it vibrates. Now you see a dead android.
3. Navigate with your volume buttons to "Recovery Mode" and select it with the power button.
4. When its booted you should see a soort of menu.
5. Select "wipe data" (or something like that). THIS WIPES YOUR DATA AND YOUR INTERNAL STORAGE (music, pictures etc..)
6. Select reboot system now.
7. Done.

Call yourself from another phone and answer, after that your phone will probably get unlocked.
In ADB or some other way to access the file system in Recovery Mode
navigate to /data/system and
delete password.key and/or gesture.key
- reboot.
Password/Gesture Lock gone.
You can use AROMA File Manager in Recovery (would have to sideload it if you didn't pre-install it)

cant disable fast boot

hi everyone, i received today my phone, it seems to be a korean import unlocked for sims but not rooted.
i had a galsaxy s2 for a few years and know how to root and flash a rom, but problem is, on my htc one m8 there is no option to disable fast boot in the battery menu
i looked everywhere on the phone, it's just not there. i looked on the net and somebody suggested CleanFLASH 1.0 just to start the phone in hboot, but can't manage to find the file anymore, links are dead, any suggestion?
thanks
anybody can help with this? I'm bloody stuck without a rooted phone!!!! thank you

Is your main problem not being able to get into bootloader (I don't see how else the fast boot power option would prevent you from rooting)? Just hold the power button until the options come up, select Restart, then when the screen goes black, immediately (before the white HTC boot screen) hold the power down rocker, and don't let go until hboot appears.
Alternately, hold power and vol up to force a reboot of the phone, then when the screen goes dark, switch to holding the vol down rocker.
Why are you worry so much on "fast boot" ?
You don't necessarily need to press power + volume down to go to hboot/bootloader.
I never disable "fast boot". Just simply restart, wait for the downanimation complete (it turn black screen) then press volume down (no holding power button) ... it will go to hboot.
Or you can plug in your device to PC with USB debugging enabled. Open a command prompt from your adb folder, type command adb reboot bootloader
thank you. i've tried all the above all afternoon, including all the tools available but phone will only either reboot, sometimes in safe mode, or reboot regularly.
I think I know what I'm doing. I need to unlock bootloader to root, but this is not possible. When connecting to pc by usb, and using tools, from comand line, computer screen just hangs and nothing else happens. with another program I can only see a tiny "fast boot...." on the bottom left corner of the screen. I cannot basically unlock the bootloader hence root the device.
another few things i notice you may be able to double check.
trying to reboot in standard recovery, the android buddy comes up on the screen, like dead, with "no command" message. then pressing volume up will take to recovery screens, never seen this before.
And last, but not least, checking the serial number from the menu > about phone > status the serial number comes as
0123456789ABCDEF
I checked with HTC support on chat and they basically gave me the registered serial number for this IMEI and told me of course that it is impossible that it has another number as this cannot be changed.
Question is... Have I got a clone here??
edit: sorry about the data, it was not set the apn, now it works. normally used to have automatically apn from sim card, but it's not the case for this phone/sim
I bet you do have a clone, does the phone has a playstore ? Install some phone specs app and see what it comes up with.

thanks guys, i've haven't been rooting for a couple of years, but really thougt something was wrong, terribly wrong. ok, will check back here when i get a real one, if needed.
I think he was talking about "Fast boot" option in battery settings and not the "Fastboot" everybody is talking about here. Nevermind. And yes, that phone is/was a clone

The subsequent responses by clpv5 and myself understood that he was talking about "Fast boot" in Settings.
The only reason the "old" root guides instructed to turn off "Fast boot" in power settings, is that this mode enabled would prevent you from entering bootloader from a "powered down" conditon (since with the "Fast boot" option enabled, the phone was never actually powered down, just a deep sleep mode).
But as we pointed out, you could always enter bootloader from a reboot, since a reboot is always a true reboot. This would work regardless of whether "Fast boot" was enabled or not in power settings.
Although it should be noted this thread is from July 2014, and the "Fast boot" option was removed some time ago.

Thanks. I was looking for an explanation like that; in fact, somehow that's why I ended up in this thread. Though, it's useful yet, since there must be lots of devices still running the 'Fast boot' option due to certain manufacturer's lack of firmware updates and because not every device in need for support out there is actually a new device

oh man, i thought i was the only one !
i have the same exact phone !
my serial number is exactly 123456789ABCDEF !!!
mine is a chinese mtk htc one m8. after hours of search i figured my phone name is alps_htc one m8 and yes my friend, is a fu..... clone !!!
i tried everything ! and search whole bunch of websites and forums like xda and xda itself, nothing happened !
i also get the => fastboot....... every time i try to go to bootloader !
this is something that you guys who trying to help here had to understand, these clone phones settings is completely different from other phones and even the original one ! hold power button then hold volume up or down, doesn't work !
every time it stock in => fastboot..... none of the buttons of the damn phone works and i have to wait until the battery drain ! real pain in the ass !!! because you know, htc one m8 does not have battery removing option, another pain in the ass !!!!!!!!!
i had a another problem too, when i wipe this clone phone, amazingly, the IMEI was gone !!! the phone said "invalid IMEI" !!! witch after hours of search i flashed it with an app from mobileuncle tools, thank to them amazing app allowed me to flash a custom IMEI from a unused phone.
now i use another htc device from the original manufacturer.
a little piece of advice, do not buy a clone phone ! cause it's going to piss you off !!!
and if you don't know how to recognize a clone from a original phone, its simple, just check the serial number, if it's feel weird, just give back the phone to seller, smile, and run out of the store !
thanks to XDA btw.

One M8 (Three UK) network unlocked - can't root?

I want to use the Root call blocker app which requires root access.
HTCdev instructions for root emphasise that 'OEM unlock' should be ticked in developer options before proceeding further. This option is not shown in my developer options screen & when I look at the bootloader screen the top item shows **LOCKED**
I guess this is why OEM unlock isn't shown.
I'm a complete novice & my only reason to root (so far....) is to use that particular call blocker. I have called HTC & they don't seem to know what i'm talking about...they think i'm asking how to get into developer options screen! Any help will be appreciated & explanations in simple terms also
Ah.. you don't reply in other thread but you open a new one.. and I asked moderator to move this to Q&A section.
Why don't you use any call blocker apps that don't require root access ? There are many of them on Play Store.
Anyway .. to root your M8, you need :
1. unlock the bootloader thru http://www.htcdev.com/
2. install TWRP recovery
3. install SuperSU.zip
There is no such thing "OEM unlock" on M8
Hi, Thanks for reply & sorry for posting in wrong section earlier.
The reason I want to use 'root call blocker' is because unlike other such apps it doesn't use the ring & hang up or divert to voicemail method. It kills the call completely & as such avoids the single ring scam which has just started to affect some phones here....mostly Vodaphone users. As yet no one is sure how the scam works but the victims are left with huge phone bills & have never called the number itemised on the bill. So......that's why I want to use that app.
Regarding Htcdev.....I have registered with them, having researched them as probably being the safest for someone with no experience & it is the reason for this post as I quote below step 2 of their instructions
''Step 2
Use the Volume buttons to select up or down. Highlight Fastboot and press the Power button.
NOTE: All new HTC devices shipped since One M9 support download mode instead of bootloader mode for this step. And for select HTC devices with Android Lollipop and all devices that receive Marshmallow, you will need to first manually enable OEM unlocking in Developer options in order to allow the bootloader to be unlocked and proceed with the next steps.''
The reason I can't proceed is because my device does not show the option for OEM unlocking....yes I do know how to get to developer options.
I have tried all the ''one click root'' methods & they haven't worked........so......any help?
There is no OEM UNLOCKING on HTC M8, only certain/newer devices have that.
In step 2, they explain how to get to fastboot screen. If your current screen show hboot (highlighted in blue) -- press power once to get to fastboot screen
As long as your screen now is showing fastboot usb (highlighted in red) when connected to PC .. you can proceed to step 5 to run command

All you have to do is:
-power off device
-insert GSM compatible SIM
-power on device
-navigate to Settings->Mobile Data->GSM/UMTS Options->Access Point Names
-in the 3 dot context menu at the top right of the APNs settings screen, you should have the option to create a new APN
Worked on mine without root. I'm rooted, now; still works.
