which firmware did you use for the update?

That is really amazing!!

I hope it works on AT&T too.

Which firmware did you use for the upgrade?

There are some beta versions and Sprint, Telus versions.
[Essential Phone Questions & Answers] ttn1185:
I used the version Open Market / Sprint | Android 8.1 Oreo (OPM1.180104.141 OTA) on https://www.essential.com/developer/current-builds
[Essential Phone Questions & Answers] tony424:
I used the same version.

Here are few updates since Yesterday.

1. Tried Sprint SIM card. I got a Chameleon as a phone network. But it didn't work. Contacted with Sprint to activate the phone. They said the phone IMEI is not registered under Sprint, may be an international version, and asked me to go to Store.

2. I was about to try this, then I saw this. I don't have AT&T sim but an expired H2O sim. I inserted H2O sim and the phone immediately showed AT&T then H20.

3. Then I tried my TMobile SIM. It worked.

Conclusion: It seems AT&T SIM card will activate this phone. Not sure about Verizon SIM. Anyone who has this one upgrade the OS to the latest version (Open Market / Sprint | Android 8.1 Oreo (OPM1.180104.141 OTA)), then insert any AT&T card, then try any other SIM. Seems this makes the phone usable and unlocked. At least I'm able to use T-Mobile sim.

Thank you ttn1185 for sharing. Your post helped solving my issue.

Essential ph 1 on Sprint network

On the Sprint network not all the SIM cards are the same. The essential ph1 needs a special SIM card. The part number is (SIMOLW416Q). Hope this helps.

---------- Post added at 09:07 PM ---------- Previous post was at 08:59 PM ----------

They sell the Sprint SIM cards at Best Buy. Their part number is different,Just give them the SIMOLW416Q part number. They will cross reference it for you.

I used a sim card used previously on an Essential Phone.
[Essential Phone Questions & Answers] OwenRW:
I'll add that mine arrived yesterday, I updated to Android 8.1 via recovery/adb and it works fine on T-Mobile. SIM was recognized straight away, no problems.
[Essential Phone Questions & Answers] baozijianke:
I guess these seller also read our posts and then decided to change their prices hahahaha
[Essential Phone Questions & Answers] stinger4321:
yeah.. just through a Verizon sim in mine.. fired right up on the network.. no issues
[Essential Phone Questions & Answers] Butter7790:
Got it. Called sprint an had them add it to their network and installed my SIM card. Working beautiful. Best deal ever.

[Essential Phone Questions & Answers] tero2012:
Hello,

I bought one of these phones but the one listed as factory unlocked (GSM) not the WiFi only version from same seller (349 USD minus 20% eBay father's day discount). I read somewhere else that essentiall mentioned those were demo units and won't receive OTA updates. Anyways, just wondering if I should not even open it and return it right away or if it is worth giving it a try.

I am planning to use it internationally on a band 4 LTE carrier. I am not even in the US, a friend will receive it and bring it overseas.

If I decide to keep it, should I care of current build installed on the device or just upgrade to the latest build available on essentiall repository page?

My doubt is if I can install latest Oreo update 8.1 having any previous 7.1.1 build.

Which upgrade method should I follow, adb sideload or the flash-all.sh one?

Thank you very much for your help.
[Essential Phone Questions & Answers] tero2012:
Hi, did you check before which build you were on before installing it, or it does not matter?

Now, from the link, which one did you use?

April 2018 Release | Oreo 8.1 - OPM1.180104.141 | Open Market / Sprint / Telu

Download (OTA) | Download (Fastboot)

The one under OTA or Fastboot?

Thanks
[Essential Phone Questions & Answers] sarfdawg:
I bought one from, I think, the same seller in Ft. Lauderdale about a month ago. I popped a Verizon SIM in, and it works perfectly. It updated immediately to Oreo 8.1, and just Friday received the latest secrity update as well as the MQA (audio) update. The only thing I can't get working correctly is WiFi calling, but HD calling just started working in the last day or two. I like it so much that I bought another one for my wife just the other day. The only thing that I would have liked to have is the USB-C to AUX adapter, but otherwise, this has been perfect. I would have thought mine would have been an international version as well, but when it identifies and works perfectly on Verizon (CDMA), that leads me to believe it's a legitimate US version.
[Essential Phone Questions & Answers] tero2012:
Did you receive OTA update or is it on the latest build?
[Essential Phone Questions & Answers] sarfdawg:
Everything has been OTA...

I'm on OPM1.180104.234. Haven't checked to see if that's the latest build, but now I'm curious.
[Essential Phone Questions & Answers] tero2012:
Yes, that is the latest build as per essentiall page.

And you bought the gsm unlocked version or the wifi only listed version?

Thanks
[Essential Phone Questions & Answers] sarfdawg:
GSM...

Not sure if I'm supposed to post the link to the listing (below). Apologies if not...

https://goo.gl/CkMYHS
[Essential Phone Questions & Answers] tero2012:
Yeah, same one I bought. Thanks for your replies. Just curious as I sent the phone to a friend who will bring it overseas and hence not easy to return back.

Will cross my fingers then
[Essential Phone Questions & Answers] sarfdawg:
Yeah, this guy is a good seller. I do wonder how he sells them NIB for so much lower than everyone else. He also only has this color (no gray or white), and they have no audio adapter. They may have come off the back of a truck, but mine has worked great, and the seller's rating is darn-near perfect.
[Essential Phone Questions & Answers] tero2012:
I read somewhere he sells demo phones without warranty.
[Essential Phone Questions & Answers] sarfdawg:
Well, if that's the case, I feel much better about the $45 I spent on the Assurant warranty. I know that works!
[Essential Phone Questions & Answers] ttn1185:
Fastboot if you want clean install.

OTA if you already setup the phone and don't want to go through it again.
[Essential Phone Questions & Answers] :
The link shows the essential for 2000$. I see a similar item for 259... Which is the one u guys all got? I may buy an essential on FB from a Sprint employee for 160$ mint condition, but I'm waiting to see if he can Sim unlock it. I have tmobile. If that deal falls through, I will definitely order one of these.. any help is appreciated. Thanks everyone
[Essential Phone Questions & Answers] sarfdawg:
Yes, that's the one, but I don't know what's going on with that price. He must have sold out his allotment and jacked up the price to keep the listing until he gets more in stock. Then again, from what I read on this thread, the two phones I have and others he sells are demos anyway; so there's no telling if he's getting any more in.

I have purchased my last carrier-branded phone; however, $160 would be tempting.
[Essential Phone Questions & Answers] :
Exactly.. well thanks for the reply.. hope this deal makes it through... I just don't wanna buy an expensive paperweight
[Essential Phone Questions & Answers] tero2012:
I got mine two days back and phone looks brand new. Everything works perfect and device got all OTA updates up to the latest one. No idea how he is selling them at this price. I bought it when it was at 349.99 and applied the eBay 20% discount for Father's day. Payed 280$ for a brand new Essential. Not bad.
[Essential Phone Questions & Answers] eKeith:
Nice move. What's the discount code?
[Essential Phone Questions & Answers] eKeith:
It's expired...
[Essential Phone Questions & Answers] tero2012:
One thing I did notice today on my device coming from this seller is that on the top of the screen (specilly top left corner) I can barely see a little of the LCD backlight soming out in between of the LCD and frame. Same where the earpiece is. Not sure f this is normal or somehow this device had a screen replacement. When pressing down the LCD glass on those corners there is little movement. Not bad, just wanted to point it out.

Only thing I am worried about is that dust can eventually go thru this little gap and affect LCD visibility. Just guessing
[Essential Phone Questions & Answers] Infect_Ed:
Are you positive that this phone doesn't have a mobile data capabilities? Because I know a way to get mobile data working on locked Essentials. It may be that the modem is just locked. If you're interested then feel free to shoot me a message.
[Desire 816 Q&A, Help & Troubleshooting] Alaxmofo:
Just got this phone about a week a ago, and figured I'd check out rooting it and such. And figured out this phone didn't have a stock recovery when I got it but boot loader was never unlocked until I did it. Now I have twrp on a stock rooted nandroid backup android 4.4.2. Can't do a OTA to lollipop says I have a variant system. My cid doesn't match there system update sent to the phone lmfao. And no ruu matched my phone found in these forums.

The reasoning I need this firmware is I'm having touch screen. Issues such as mirrored touches sometimes. Other times the phone will run good. Can't run lollipop roms or marshmallow cause my firmware isn't updated for it smh. I messaged HTC about this and sent a request to there team in charge and will give me an update in 7-10 business days.

[Samsung Galaxy S7 Questions and Answers] beevme:
I currently have a Samsung Galaxy S7 (Exynos Version) and been thinking of switching to the Blu Vivo X for the 4010+ mah battery, 64gb internal storage, and 4 cameras. Both phone has 4 GB and rams and an Octacore CPU. The Blu Vivo X is currently more than a $100 less than the Samsung Galaxy S7 (Exynos Version).

What's your thought on the Blu Vivo X and would it be worth switching to it from a Samsung Galaxy S7 (Exynos Version), even though the Blu Vivo X uses a 720p screen, and Blu has been known for having adwares in their phones in the past?

[Samsung Galaxy S7 Questions and Answers] cristiandiaconu6:
No way!!! Why you would do that? It`s more like a downgrade.. If you really want a change, something stock, more storage, more ram, quickly software updates and maybe a better battery backup, you can change the s7 for a OnePlus 5T, or simply you can wait for OnePlus 6 which is launching in june..
[Samsung Galaxy S7 Questions and Answers] Meshuggahblast:
Yes it's true, these are the best alternative to my point of view too, but the only thing is that it's not on the same budget level (250$ for the Blu Vivo X and 500$ or more for the OnePlus phones). Though, you summed up all I said very well, S7 to Vivo X is a downgrade.
[Samsung Galaxy S8 Questions and Answers] wezzel98765:
Hello everybody, I have got a wireless in car charging dock and when the phone is in use for example when using satellite navigation or whilst I have Pokemon go on the screen and the screen lit up, the phone discharges. It is charging but at a slower rate than it would be if it wasn't on screen on. I have tried three charging docks and four in car chargers including quick charge chargers and just standard two amp chargers and it still has exactly the same effect. It always seems to charge fine for the first 4 or 5 minutes but then after it takes down to an average use of minus 100 - 200 milliamps. I assume there is a restriction on the phone to reduce heat or something and the only option I have when using the phone whilst in the car, not physically using but rather using the phone to display sat nav etc is to use a cable rather than wireless charging?

It frustrates me that it charges correctly to start with, but then it gets to the point where it is discharging rather than charging. It is much more convenient than having to keep unplugging and plugging in the phone

I'm the newbiest of them all, I think I bricked my brand new Excalibur!!!

Sorry if I'm posting in the wrong place, but I need heeeelp!

O.K., here it is:

I just downloaded kavana's 080314 WM6.1 installer for the HTC Excalibur, I ran the exe and followed instructions, afterwards, the ROM app opened and started upgrading the phone but it got stuck at 1%, it made be go thru the recovery process several times (unplug, turn off, disconnect battery, turn on) but it always started on tricolor mode and always got stuck on 1%, after a third recovery process the ROM app just quit and left me hanging on tricolor mode!!!

Activesync won't connect now, I try to run kavana's exe again but it doesn't recognize the phone either, the phone is on, conected (windows makes the usb sound for connection) but it is not recongized, it's as if it's not plugged.

It is stuck on tricolor mode and I don't know what to do!

Please help me!!!
[HTC Excalibur] glenbo:
Try the dicussion thread "Bricked my T Mobile phone" there are plenty of answers there.
[HTC Excalibur] velascoperroni:
Will this work?

I saw this on said thread, but I presume it applies for a Herald phone, will it work?

The tricolor mode is "bootloader mode"?

Isn't there some sort of restart that can fix it?

Can someone elaborate on this? I'm really a super-noob!!!

"Try a SD card flash to unbrick your device

This is how:

MAKE SURE THE HERALD IS FULLY CHARGED BEFORE STARTING THE PROCES

#01 Download your original RUU

#02 Download (if not yet installed) WinRar and install

#03 Copy your full sd micro card to your harddisk and format your card with FAT 32

#04 Rightclick the downloaded exe file with your original RUU, click Unpack here

#05 In the map the will be created you will find a file (or similar) called RUU_signed.nbh. Copy this file to your formated sd microcard.

#06 Rename the file to Heraimg.nbh

#07 Get your Herald into bootloader modus by pressing the comm manager button and the camera button and pressing the reset button at the same time. Do not release both buttons until your in bootloader.

#08 Once in bootloader pop in your sd micro card.

#09 As soon as your card is popped in the screen will say something like "Reading SD card". Wait it out till it says "Push button to start" and slide the indicated volume slider down.

#10 The Herald will start the flashing proces. Wait it out till it says "Press any button" and hit the send button.

#11 Perform a hard reset

#12 Voila! Your back in business"
[HTC Excalibur] timothyjok:
I believe you didn't application unlock it first. I had same issues. I finally got it to load. I don't think you bricked it. Remove battery wait a few seconds and restart phone
[HTC Excalibur] velascoperroni:
Already did that... still on "brick" mode...

Question: is my warranty still valid? I bought it 3 days ago.
[HTC Excalibur] cicciocant:
you can solve simply to launch original upgrade to wm6 rom
[HTC Excalibur] pfunkside:
Do try these procedures first. I'm just throwing it out there but if you try again it is probably a better choice to flash to WM6 first. Then try flashing to the 6.1.

I'm sure you can return it but come up with a believable excuse.
[HTC Excalibur] Technology:
Yes, You Are Correct!

Yes, that is the correct path for him to take, install a 6.0 ROM first, before installing a 6.1 ROM. I suggest he install the T-Mo official wm6, just to get things started in the right direction again.

(1) If the device is still in the tri color mode (bootloader mode), that's a very good sign, it's not bricked. Connect the device to your PC via active sync in the tri color mode, you may think that the device is not connected to Your PC but it is, it may not look like it's connected, run the official T-Mo wm6 ROM RUU WWE, it will install on your device as long as your device is in the tri color mode.

(2)Once you get the wm6 ROM installed on your device, you must first SDA_ApplicationUnlock your device, next you want to Certificate AppUnlock and SurrealApplication Unlock your phone. Now, the reason you are doing all these unlocks are because you coming off the T-Mo wm6 ROM.

(3)After all this have been done, it now ok to try to install the 6.1 ROM on your device.......!
[HTC Excalibur] velascoperroni:
Great support!!! But now comes the obvious question from the n00b of the n00bs!!!

Got it, now the big question is: how to flash to WM6?

Is it done by the steps I posted early? (formatting SD, etc.)

Also, where do I get the T-mobile RUU?

Finally, there are a few things you should know, my phone was bought in Mexico, under the cellphone company Movistar (Spain's Telefonica and I've heard U.S. AT&T), it had WM5 before I "bricked" it (hehehe).

When I turn it now, a few miliseconds before the tricolor screen I can read in the phone a "waiting for SD card" message when the tricolor screen comes on, I get this version of RUU 1.15.000.

I appreciate all your help, as a contribution to this amazing community, when I get thru this, I hereby commit myself to write a fully understandable guide for noobs with the same problem (not too long).
[HTC Excalibur] Technology:
T-Mo Wm6

Is your mobile device still in the tri color mode, if so just connect it back to your PC via active sync, It will accept the download! OK you can get the T-Mo wm6 at T-Mo's website, if not I will send you a link with the T-Mo wm6 RUU. Don't panic, you are still in the game.......!
[HTC Excalibur] velascoperroni:
Update!! Phone unbricked but still on WM5!

Ok... I used this ROM: HTC_S620_WWE_1.27.405.1_4.1.13.44_02.94.90_Ship.exe

It went thru the upgrading process but got stuck at 3%, anyway, it finished with a message like "this ROM cannot be used for your phone" or something and restored WM5.

Now I will follow instructions on the thread: "The Full Guide To Upgrading From Windows Mobile 5 to 6" and I'll be posting my acomplishments on this thread.

Question: The reasons for me not being still able to upgrade may be:

1. I haven't unlocked phone,

2. My phone is for Mexico and cellphone co. "Movistar", or

3. I'm running Windows XP as a virtual machine (via parallels) on an intel Macintosh and somehow there's a problem with the USB drivers.

I'm rooting for option 1 (but kavana's upgrade was supposed to already unlocked it). Option 3 maybe but then, why do I get Activesync to run? Option 2 would be a bummer!

A easy frix, but read the instructions very carefully, jockyw2001 thread is located in the sticky section. What you are looking for will be in post #1.........!
[HTC Excalibur] Technology:
New Instructions

Run the Excalibur Uspl-CID ByPass.zip, extraxt on your PC and open it there, you will see several file folders. Open the one that say (uspl) MS-Dos batch File, follow on screen instructions by pressing any key. This time when you see the white screen on your device do not panic! Run the HTC WM 6 ROM, this is done while the screen is still white on your device. Just follow the on screen instructions on your PC.............!
[HTC Excalibur] velascoperroni:
Now I definitively bricked it!

I ran the CID unbloker, screen went blank, ran the ROM, it got to 16% and made me do a recovery, after the recovery it gave me the same "invalid vendor id" message and it automatically restarted the phone, but...

The restart stopped at the HTC intro screen!! I've restarted it several times and it just stops on the first HTC logo screen... even a hard reset won't fix it!!!

HEEEEEEEEEEEEEEEEEELP!!!
[HTC Excalibur] pfunkside:
Here is a visual aid.

Still Bricked!!!

Yeah!!! superb visual aid!!!

I just wish I had seen it before I bricked it!!!!

This is the current state of my phone: I press power, I see a white screen with the HTC logo in the middle, the phone vibrates, still the same HTC logo... and it is stuck that way! I can't turn it off, I have to take out the battery!!

I've tried a hard reset, same thing happens! It stays stuck on the HTC logo screen and I'm forced to pull the battery out for the phone to shut down.

It is obviously not recognized in any way when I plug it to the PC's USB.

What made this happen? HTC Generic ROM got stuck on 16% before telling me "invalid vendor id", restarted the phone and voila: brick!!

Boy, I wish I was back in the tricolor mode!!!

IS THERE NOTHING I CAN DO?

I'm seriously thinking about going back to the vendor on monday and saying: It was like this when I woke up (I just bought it three days ago!!!)
[HTC Excalibur] ashasaur:
If it gets that far, it doesnt seem totally bricked, ima PC man, so this may be off, but it seems like some kinda bootloader error on the phone itself....IE, the HTC screen is all that the bootloader tells the phone to load. Have you tried forcing the phone into bootloader mode?
[HTC Excalibur] velascoperroni:
I Looooooove Google!!!

OK... I found a turnaround for the problem... got it to go to bootloader mode!!!

Whenever something like these happens to you this is the hard way to put your excalibur/dash in bootloader mode:

1. Take out battery and sd card;

2. Plug your USB cable to your PC (not yet to the phone)

3. Press and keep holding the SIMB. key (the one with the camera next to the space bar)

4. Plug your USB cable to your phone (while still pressing the SIMB. key)

5. Voila: You are in bootloader mode!!

This was gotten for a 15 min. search in google!!

Now... I'll keep going with my WM5 to WM6 upgrade...
