I restore My X820 32GB using qloader but the fp dont work..

I dont tried the fp after restore but after flash a custom rom after restore.

I tried unbrick method, and switching modems on my x829 but got no luck.

Now I have ordered new FP sensor from Aliexpress and planing to replace it when arrives.

I received mine two days ago, and the FP its working well and fast, just changed the 16s to indian 19s and still working.
[LeEco Le Max 2 Guides, News, & Discussion] zeffiro:
What custom ROM did you flashed? Did you try to recalibrate and then test fingerrpint?

There are some custom ROMs that do not have the option to recalibrate the fingerprint. That may have been it.
[LeEco Le Max 2 Guides, News, & Discussion] onecryon:
First rom cuoco 16s after 20s after madmax 20s and now madmax 23s.. Always i tried with recalibrate and try to add new fp

Also tried with different modem china and dev

Initially when i recived the device the fp working wery well but after the 2 or 3 flash rom (if i remember from cuoco 20s to madmax 20s) stop working
[LeEco Le Max 2 Guides, News, & Discussion] zeffiro:
I use the Small EUI v12.

If you can, do this:

- do the unbrick procedure

- install the Small EUI v12

- install patchfix v12

- recalibrates the fingerprint and restarts

- try adding a new digital

The Cuoco92 includes some things that Small EUI not "include" in the base system.

I have 2 x829 4/64 GB Gold and Grey. One with fingerprint problem and the other works perfectly. I did the steps below:

1) unbrick proc. reboot to dev rom, calibrate FP and test FP - not working.

2) install TWRP, Wipe Sys, Cache, Dalvik, Data, Storage and then Format Data (I found Format Data is necessary or else the partition only shows 10 GB instead of 64 GB after the unbrick proc).

3) install Small EUI v12, patch v12, recalibrate, restart and add fingerprint.

FP still not working. CatLog is showing errors on the qfingerprintservice on the problematic phone but not the other. I think it must be hardware. I have configured both identically but no luck. My next step would be to replace the fingerprint button purchased from AliExpress.

Does he give no signal when he tries to register a fingerprint?

If this procedure did not work for you, unfortunately it must be hardware itself.

In my case, whenever it was bugged (which seemed to be software) this always solved.

Sorry for not helping anymore.

I got X829 bought it last week, after 2-3 days Fingerprint stop working. I installed TWRP and backup rom that come with the phone (5.8 (16S)

I flashed this rom:

- Revolution 23S by Steve Mars, FP still working

- SmallEui v12 by Aurel, FP was working and later stopped working on this rom

- I flash Madsurfer (23S) Sense rom, FP never work, the sensor is just not functioning, no vibrate nothing

I think most people aware Fingerprint is problematic on this Le Max 2. If its working its good if not for me it's ok.

I received two of they grey 4GB/64GB X829s from Banggood yesterday and the fingerprint reader works well on mine so far. I'll wait a few days before I start unlocking the bootloader, rooting, or flashing ROMs, so that I can get a good feel of the phone in general and fingerprint sensor.

I haven't tried the other one bought because it was supposed to be for my mom who lost her phone, but someone returned it to her, so I am selling a sealed Le Max 2 if anyone is interested. I even have a new black case for it, that's pretty much a Spigen Rugged Armor quality and material wise. I ship from Los Angeles, California.

Just recieved third Le max 2 ("new" 6/64gb X820 variant), from banggood again with dead Fp sensor ?. Thats 2 out of 3 phones with dead sensor.Only x820 4/32gb variant works like a charm.
[LeEco Le Max 2 Guides, News, & Discussion] rickyx32:
That's crazy man, I've just received two grey 4/64GB X829s and the one I chose works as it should... I'm going to have to open the other one to check. So they're completely dead? No response at all when you try to register your finger? What have you done to the other ones?

Edit: I just opened the second one I bought and I was able to register my fingerprint on it without issue.
[LeEco Le Max 2 Guides, News, & Discussion] sepacek:
Yes,its completely dead,no response at all if i try add fingerprint. I have to Wait for new Fp sensor from Ali.

My first one x829's Fp sensor stopped working after few hours usage.

You're such a lucker :laugh:
[LeEco Le Max 2 Guides, News, & Discussion] rickyx32:
Well I've only used it for about a day... I'll wait a week before I start flashing anything on them, then I'll only flash on one to see if it really is a hardware defect, or just a software issue, or both. It sounds like you have several of these devices... Do you return them? Where do you buy them from, or do you sell them?
[LeEco Le Max 2 Guides, News, & Discussion] sepacek:
All of them are from banggood, they gave me 20usd discount coupon for each because shipping cost Back to China is too high.I m not a (Re)seller, its Just for my family's personal use only.
[LeEco Le Max 2 Guides, News, & Discussion] DJ_BARO:
A Modem can improve this!

This helps for some people who have software related problems!

Hi Guys i had the same problem with my X829 Device. But i got a solution to highly improve this:

Download the uploaded Modem from here

https://goo.gl/i1iDq9

And flash it after installing your rom (or if you want to stick with your current rom, just install it and reboot)

Now the fingerprint with X829 Device at least is much more responsive and quicker: Yes it's not perfect and sometimes after a long period of time you wanna unlock your phone with fingerprint (after couple hours) it needs for the first time a couple of secs to be waken up (i mean that the sensor looks like gonna sleeping after not been used more than one hour and it takes some sec, to recognize your finger when pressing it but after that fine :) ) But otherwise its now pretty reliable.

This works with STOCK and CUSTOM ROMS like CM 13/14.x, tested!

Tell me if it improved for your device too

:fingers-crossed:
[LeEco Le Max 2 Guides, News, & Discussion] diabolyk34:
Hi,

I have already tested it with no amelioration...

Mine was working well as yesterday.

It was working at 10:00AM and 1 hour later no more working... without doing anything...

just a question, you just flash without wiping anything ?

:'(
[LeEco Le Max 2 Guides, News, & Discussion] DJ_BARO:
Hmm thats a bummer. But how i said: It looks like after not using it for more than a hour, the FP is going to sleep: It will wake up though if you put your finger on for maybe 3 secs.

But could also be i'm wrong and you have an hardware related issue

:(
[LeEco Le Max 2 Guides, News, & Discussion] diabolyk34:
yes but it's not due to that because it was well working before... also after an hour of inactivity...

I have many nandroid and all i need but i don't think it will help me for that.

i think also a HW issue...

here the video i made for banggood to show them the problem : https://www.youtube.com/watch?v=BFGVySygpjI

the sensor detect nothing, no vibration...

just taking multiple photos if i activate the sensor for camera...

Any feedbacks of the replacement sensor on aliexpress?
[LeEco Le Max 2 Guides, News, & Discussion] jklph:
My fingerprint sensor finally arrived from AliExpress. I was able to replace it and confirm that it was a hardware issue.

The hardest part was extracting the LCD/Digitizer. Go slow and gentle. I broke the LCD in the process and had to order from AliExpress for around $35. It just arrived yesterday. I put it all back together and everything works fine except magnetometer/compass is no longer working. I'll do some more troubleshooting later.

FP works fast and flawlessly now.

Part and Tools I used:

FP button - https://www.aliexpress.com/item/f/32797969465.html

Suction (use gently, this is too powerful) - https://www.aliexpress.com/item/s/32668307812.html

Adhesive and pryer - http://a.co/cB7Rvjw

Spudger, screwdriver and scraper to remove old adhesive - http://a.co/5Hn4l9I

>90%+ alcohol for cleaning sticky residue.

LCD/Digitzer (since I broke mine) - https://www.aliexpress.com/item/1/32772784644.html

The cover between LCD and motherboard is also held by few sticky tapes so you'll have to pry it out slowly.

Both gray and gold variants uses the same silver color FP button part. I know since I have a gold and gray version.

How i "made" my fingerprint sensor to work

Before a few minutes (it's never too late) i realized that there was no problem with my fingerprint sensor but in fact with the way i was trying to register my fingerprint. Until now i was putting my finger on the sensor waiting for "the vibration" in order to understand that the registration was completed. Of course this "method" always failed. So before a few minutes i found out that i have to tap and remove my finger from the sensor continuously until the registration is completed (maybe this procedure is well known to the most of the people here but i assume that there is also people like me who also tried to make the registration the wrong way). FP sensor is working now and quite fast i think. I don't know that it will keeps working for a long time but i know for sure that the sensor was not defected for the start

[LeEco Le Max 2 Guides, News, & Discussion] davidnewton:
Fingerprint on my Le Max2 is dead for over 3 months. After installing Lineage OS14.1, it starts to have response. When I try to register fingerprint, it can get first read, then no more response again, and stuck as the attached screen shot. So it might be hopeful that hardware may still work.

My sensor stoped one week after I received the phone.

Until now, even trying to flash many roms or modems, nothing happens. Sometimes the FP worked strange taking pictures randomly.

But now, two months after, the FB is working normal. I tried to register a fingerprint and it is working pretty good.

Maybe is a software problem.

Hello. I followed this thread since my fingerprint on a X829 quit working just after 2 days of opening the box. Tried all the software tricks and no one worked. As I got it for a real bargain price and loved screen, camera and performance, decided to keep and ordered a fingerprint reader replacement. Ordered it from Aliexpress for less than $10, took almost a month to receive. I repair phones as a hobby, i have to say this phone is REALLY hard to open, as screen is fragile and only glued, no screws to open. Replaced the sensor, (had to disassembly all the phone). Worked like a charm!... I was able to register fingerprints, etc. But.... again 2 days after, having my phone in jeans pocket, took it out, felt the sensor area REALLY hot for a while, and then, no response. Again, no fingerprints registered, try calibration, no response, exactly same as before replacement. Phone has electrical-electronical issues with fingerprint. So sad... =(
