Please tell me your exact phone model.

You can find all that's needed to flash an 816g (MT6592) dual-SIM device on this site.
If your device is in bootloop, watch this video to learn how to disconnect the battery, so your device can be shut down. SP Flash Tools will only work, if your phone is completely shut-down, otherwise it will continue to bootloop and your pc/the flashtool won't connect.

Under Desire 816, there are many variants... @nemesis666999 will have to tell his EXACT phone model..which a5_xxx model do you have?

There is no other variant of desire d816G. This device is one of a few other models with an mtk processor.
If it's really a desire d816G dual sim, only the method I posted before will work.
Besides, he posted in the wrong thread to begin with. 816G is dual sim, he posted he's got a single sim version.

Htc desire 816 (A5_DWG) stuck in bootloop.
hey there, just wanted to know is this helpful for my htc d816 a5_dwg as well. cause even its stuck in a boot loop. for some reason I don't know what my phone goes black every time I try to enter recovery mode. I flashed a twrp.image file and since then its stuck in a boot loop. please help. and also if u could comment on the blank screen problem.

HELP PLEASEEEE Excalibur S621 DATA CRASHES

I'm having troubles with my HTC Excalibur S621, i'm from Mexico.
The problem is that when I put a SIM on it, the screen gets locked with the next window:
FATAL ERROR
DATA CRASHES. PLEASE CONTACT SERVICE.
It only happens when I boot my HTC with a SIM and radio ON, if the radio is OFF or the HTC without SIM it boots ok and can work it without any trouble. I hope you can help me, i'm new to this forum. I've managed to re flash it with several flashes but it keeps the same. Thanks in advance

Have you tried another sim from your carrier? or from any other carrier? is your phone sim unlock?

[Q] Unalble to sim-unlock even when using the "Sim unlock utility"

Good morning,
I know that the issur have been treated many times in the forum, but I hope that I can get the answer of an expert for my case.
I'm trying to sim-unlock a HTC Desire smartphone (locked to the french operator bouygue telecom). I've tried to use the sim unlock utility, explaned in one of the forum's threads, the phone restarts but the sim still unlocked.
My question is: flashing a new stock radio would solve my issue? I'm ready to do some advanced manipulations to resolve this issue, but needs more help to find the way to do it.
Thanks folks.
Should have posted in the utility thread as opposed to here - not as many people will look at it

I've seen many members succeed using the utility thread, but that wasn't my case, so I wanted to know if flashing a new radio would resolve the problem.
Have you tried this? No further than yesterday I unlocked my Desire from Vodafone network. Just download the iso, burn it to a cd, boot your computer from it, restart your phone in hboot (power and volume down) then connect it to the pc - wait for a few seconds and voila! your phone is unlocked.

hello,
i have the same problem and i have asked HTC assistance, they told me that its normal, and when it will be our devices turn , update will show up by itself.
im not sure that its possible but anyway i share my experience with desire 816 dual sim
I don't think that's true because I have seen that option on my friends HTC even without any updates available.
Btw do you think flashing the stock Rom will fix that??

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.
U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.
Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...
Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Thanks for your reply...
Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?
Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?
Please help.....
I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help
Any idea's?
Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.
Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help
Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).
Maybe it will help ... LG G4 CAM

If already tried all and still no movement, pls take it to Lenovo Service Center and let them sort this... just flash the stock roms via QFIL to get locked status so that warranty is valid.
PS: This is wrong sub-forum...it is for discussion and not Q&A.
