[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] dh350nwo:
Had the same error pop up. Did all the recommended fixes (new battery, wake Locke, etc.) and the phone finally quit after the new battery fully did charged. Tried like hell to get it to boot. No joy. Seems to be a common issue.

Had a glimmer of hope today when I plugged it in and the charging battery display popped up, but my dumb ass couldn't leave well enough alone and I unplugged it and held the power button to start it up. Nope. Fully dead again. Going to leave it plugged in and see if any life is left. Would really love to get some data off the internal memory.

And no, trying to Odin into it provides no results. Windows just sees a dead device and cannot communicate with it.

***Edit***

I've seen some posts saying that this may be related to updated firmware. I can say that in my specific case I have very old firmware and haven't updated to 6.01 as many suspect caused the failure. Pretty sure this is flat out hard ware failure on behalf of Samsung.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
Have you tried removing battery and letting it sit without battery for a while? May take hours, longer or just minutes. Remove the battery and try later if it doesn't boot.

There's a chance you might get a boot to transfer some data from internal memory. I believe the battery pull plus cooling may increase likelihood of boot. IMO, an A.C. register blowing cool air on it or forced air from a fan may be better than fridge or freezer; the condensation should be avoided.

Ultimately you likely need a repair. Samsung Support may be offering eMMC replacement for $75 USD but turnaround may take a week or more.

holding the power button for 30+ seconds or repeatedly for 10-15sec at a time without any power source has the same effect, if not better. the technique is called "static discharge"

it's an old fix for BIOS issues on old laptops

Many Thanks for your rlp, i have tried each and every method but all in vain, got repair @ 20$ it run flawless for max 3 days then he turned off permanently :(:( . They suggest me to change it's motherboard, it will cost 80$ with no warranty. As i already spent 20$ so i decided move on to NOTE 5.

I Sold Note 4 for its LCD Panel at 100$. Now Enjoying NOTE 5 Dual with 7.0 Nougat. :cool::cool::cool:

Peace ...
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Sterist:
I would say that was a bad idea because

1. slower cpu

2. replacing battery = repair center visit (and it's probably already seen a lot of use!)

3. no sdcard slot

4. no IR blaster
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] rassel2k:
This is 100% Hardware Issue not Software. Easy Fix! To get proof yourself:

1. Disassemble the phone, Re-Solder the IC: U3002 Section (Under the SIM and SD Flex) works 100%. "ddi...Error" gone for mine & still now Ok (two weeks running), except a little Lagging & Restart detected some times. I just ignore them

2. After just Disconnecting the SIM & SD Card flex from MB also worked as reported some other devices! (Flex Issue???)

Another interesting thing is, most of those phones goes to QHS_USB Download mode when Restarted and bricked! 10 Seconds of Battery removal solve the issue too....

Anyway, none of the above solutions are guaranteed. I Just identify the real problem, real solutions depends on real Exparts.

Thanks.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] celticpride:
Hello, I have this exact issue going on with my phone. Here's the rundown to how it started. (Btw, this is a non-rooted Note 4)

I was using the phone as normal and it was pushing for the G1 Firmware update, but I had delayed in order to run a backup of my stuff. A few days went by, and the 2 days before this started the phone began lagging heavily, and then would reset itself a few times. Then I made the mistake of accidentally hitting the update button. It ran its update, and came back and said the update failed.

Since then, I have been experiencing the exact issue that OP wrote about, whereas I can get it working briefly to recover some internal storage information, but that's about it. Any ideas?
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Death-Dealer:
Move on to the note 8. I've been with the note 4 since launch day and the emmc read fail is exactly y it's time to move on. I'm on my 3rd note 4 because of the emmc read fail and was just waiting for the note 8. Anything you find online to help with this is pretty much bs as this is a internal mem failure. The N4 is such a great phone and I wish Samsung didn't F it up up like this. Sorry, but grab what data you can off it. I didn't get that chance the second time this happened.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] shapechanger:
I have run into a similar issue with my phone, and was looking for some advice. It started with my phone running really really slow, and it would freeze when typing. Eventually i would turn it on and get the weird mmc_read error. After resetting it a couple times,m it would boot in the Welcome Samsung screen, and get a continuous force close of random thing and it will not stop. I installed the Samsung drives and was able to pull up my phone, but the folder is empty. Does this mean my phone deleted everything on the phone? I had pulled the sd card soon after it started messing up, but the internal memory was nearly full, and was wondering if there was another way to attempt to get my information off of the device.

thanks in advance

Hi!

did you change the charging jack or just removed it from the motherboard? can you charge your phone in both turnet on and off state? can you boot the phone into recovery mode or download mode if you want to or they don't work anymore?﻿

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] pandit:
I did and it is the solution :) But I broke one flatcable from the screen and the digitizer is not working anymore. my stupid fault. Lucky the screens are inexpensive on ebay and Aliexpress. But which one is good? they say Burn Shadow AMOLED LCD , Is this bad?

Some advise?

After almost six months of waiting, here it is: the first stable release of Nougat for our Elephone P9000 European and Asian variant (there's no support for US model in this ROM)

Original thread: http://bbs.elephone.hk/thread-13393-1-1.html

Firmware Download (MEGA)

SPFlashTool (MEGA)

Elephone MTK drivers (Driver Test Signing required) (MEGA)

--- First Impressions ---

- Installation was OK. Did a dirty flash over the previous BETA without overwriting USERDATA.

- Had to reflash TWRP, even if I unchecked RECOVERY while flashing.

- Magisk 12 is working like a charm, with ROOT support.

- Laser focus is working, option is now in camera app instead of a global setting.

- Fingerprint reader is working, feels faster but still lacks a little precision.

- Users report that fast charging is working.

- SafetyNet still reports CTS profile mismatch.

- This version is not available as OTA, but next one should be OTA compatible.

ok flashed it looks great.

BUT when i make a phonecall the screen sensor is not working propperly.

my screen goed on and of so when on the phone you press different things on the screen with your cheek.

20% in 16 minutes... looks like it's working fine for me. The screen just wasn't updated...

View attachment 4135078 View attachment 4135079

BTW, I'm using Elephone's original fast charger and cable...

---

2:31 an is fully charged. 75 minutes for 85%... I remember that before it did 100% in about 70 minutes. Good thing, even if it's a little slower, it didn't get insanely hot... so in the end they changed the fast charge function, or it's just charging really quick with the standard 5V2A mode... Maybe they just limited it to 9V fast charging instead of the full 12V? Any ideas?
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] DonMagnifico:
Whats your definition of fast charging? For me fast charging is working:

from 20% to 80% about 45min with original Elephone fast charger and original Elephone cable

Usually i charge the battery only up to about 80%
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Pro4TLZZ:
Fast charging with pump express has not worked since the 20160608 ROM, if you really want to see how fast pump express plus is then flash 20160531 which charges a whole 100 in 67 minutes. On this ROM it takes me 2 hours to charge from 30 to 100. Before on pump express it would take 55 minutes and without it before this ROM it would take 90 minutes. This ROM charges even slower. And you can't check the voltage since the power is not present in this mtk app
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] matov3:
What is the battery life?
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] DonMagnifico:
Pump express never works until 100%! For me a full charge with nougat needs about 90 min (from 10 to 100%), for me and on my P9000, fast charging is working

Battery Life is like in marshmallow
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Pro4TLZZ:
It does not work. The phone doesnt even charge above 5v and 8w in this ROM. If you don't know how to check it then turn off your phone whilst charging and see if it has a 3d battery animation instead of the 2d one
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] DonMagnifico:
I do not care about a missing animation. I see the reality on my p9000, as i have already said, charging time in real life from 20 to 80% is about 45min on my phone.

If you say fast charging is not working on your phone i do accept this, on my phone its working!
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
It's not about how quickly your phone charges, it's about the technology involved.

I think mine is not fully working, as it still is charging fast, but not as fast as before in last the Nougat beta (That's why I think it may be working at up to 9V). I'll try to get an USB power meter, but here in my country and city they're really scarce... and the few that I've found are for 5V operation only...

What is this animation like? Is it like waving blue water (I remember that in the latest beta)? Here at work, with normal charger I get calm blue water filling the battery. I'll check with the PE+ charger when I get home.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Pro4TLZZ:
It's a 3d image of the battery rather than the flat 2d one which is perfectly rectangular
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
I think I've never seen it, even with the latest Nougat beta where PE+ was definitely working... as my phone charged full in about 70 minutes and got hot as hell in the oven. For my it always has been a rectangular battery with waving blue water inside.

---

Factory Mode reports charging voltage of 4.7 volts with the PE+ charger, almost the same as the standard 5.0V2A charger included with my P9000 or the P5000's charger... so at least in Factory Mode PE+ is not working. Also I got blue slooshing water in the OFF battery indicator with the 3 chargers tested. So I bet it's a systemwide issue unless PE+ doesn't activate itself in Factory mode.

BTW, a fun fact: I've never could get OTG to work with my phone, and in Factory Mode there is an OTG test marked in red instead of the green of all the other options... OTG Status: FAIL... I'll try Factory Mode later with something connected in OTG mode...

---

OTG Confirmed working :D

View attachment 4136102

Check the mouse pointer just around the Whatsapp icon...

BTW, OTG only works with USB type C OTG adapters; I tried to use an microUSB OTG adapter (the one included with my P5000) with a microUSB to Type C adapter, and it didn't work and also prevented OTG from working until a reboot. With the Type C OTG adapter it even pass the Factory Mode OTG test :D
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Fran Montero:
Does the cable make a difference while charging in order to fast charge or just the charger itself???
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
I understand that you need a good quality cable for PumpExpress+ to work. I remember that when PE+ was working for me, it didn't work with a generic cable and just worked with the original cable included with my phone and with another good quality cable that I bought...
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Pro4TLZZ:
I used a USB c cable with a 56k resistor. It worked fine on the ROMs that worked with pe+. The included one in the box shouldn't be plugged in the PC since it doesn't have the 56k resistor
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] abadjavier2001:
Could we install it on P9000 Lite versión??
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
I think it isn't compatible. Latest rom was 2016/06/21 I think... but as there is supposedly just minor differences between P9000 and Lite *wink*wink*build.prop*wink*wink, once the Nougat release goes gold you should have a Nougat rom too, official or not.

Hi guys,

I've also posted this question in Elephone Forum, but maybe here I'm getting more qualified informations:

I've updated my P9000 with this 7.0 nougat version and everything is working smooth except my GPS. It's really crap since the update, even more unstable than in 6.0 marshmallow.

I've flashed without userdata in "Download Only" mode.

Could a flash with overwriting the userdata fix the GPS problem?

And should I flash in mode "Firmware Upgrade" or is "Downlod Only" sufficient?
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] moonwonder:
Good evening,

everithing works fine here.

Installed using "format all + download" on sp flash tool.

- gps working better than 6.0

- Bluetooth work

- fingerprint was better (8/10 working)

- battery was worse till re-calibration (maked by advanced battery calibrator)

Sometimes system UI crash.

Regards

So you guys have a good and acourate working GPS?

Did you flash with userdata?

What mode did you use?
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Hexyl:
I did format+download because normal flash corrupted the nvram. After that I used Maui meta to restore my imei numbers.

Unticking user data may cause problems. Best is to do a clean flash. So backup your data.

And yes my GPS is working better than in previous stock ROM. I use Sygic for navigation and it works perfectly.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] giniman:
THX for the info.

How did you backup your nvram?

With flash tools and read back or did you use any other program?

Did you also backup userdata and other partitions?
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] Hexyl:
I did not backup nvram. It was corrupted during flash. I do not know how to backup nvram but have seen some tutorials. Searching mtk nvram backup should give you enough information. I did a backup of my apps in titanium backup. For pictures etc, Just put them on your SD card or PC.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] giniman:
Ah OK, I see.

Will try to flash with userdata in mode firmware update and will hopefully get a better working GPS.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
You can Backup your NVRAM with TWRP. BUT that doesn't mean that you can restore between different android versions, as the changes in the kernel sometimes makes the restore impossible.

Some time ago I did a NVRAM backup of my Android Marshmallow 6.0 system, and upgraded to the Nougat 7.0 beta. When I tried to restore Marshmallow it was impossible UNLESS I flashed the older 6.0 ROM before attemping the restore.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
I think the "No Userdata" flash is only working for the people coming from the earlier 7.0 betas. I did it that way and I've had no problems, no FC's, just a couple of reboots while using USB tethering for WiFi...
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] giniman:
Well I flashed from 6.0 to 7.0 without user data and everything seems to run smooth without FC's except GPS, which is really crap! Had to clear some app caches in order to get them running, but the overall impression of this rom is pretty good.

Will try to flash with userdata on weekend and will give feedback whether there has been an improvement of the GPS or not.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
GPS is working better the ever for me. Very quick fixes​ and good accuracy.

As for the userdata, I think the best way to keep your apps and data is the trusty old Titanium Backup. I bought it and have been using it from the old Eclair Android days...

Hey guys!

I got some news in the PumpExpress+ side of things. I received my USB Multi Tester in the mail, so the first thing I did was to check whether PumpExpress+ was really working or not, or if it was just a placebo effect or something.

The thing is, it 'is' working, but it isn't working as intended. With my original Elephone PE+ charger and my original Elephone Cable, I could check that indeed, the phone was charging at up to 12V, as expected for PE+. BUT it is just charging at about 0.8-0.9 Amps of current. So that's why it isn't burning like a supernova when charging as it was with 7.0 earlier betas or 6.0 stable... but even if it's charging at 12V it is still about a good 30-35% below its maximum potential speed (The charger is rated for up to 1.25A at 12V) and that explains the 80+ minutes for a full charge. What still puzzles me is why some users are experiencing 2+ hours charging times, when even with a regular 2A charger you get almost the same charge times as with the PE+ charger... and that in itself is puzzling... as 5V 2A is almost as fast as the PE+ charger... weird. Still I prefer my Elephone charging a little slow than melting :cool:

[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] djelloul:
Hi JocPro.

Could you tell us which ROM version did you use to confirm that the Pump Express + is working properly?

I'm using last stable 7.0 Android stock ROM currently and PE+ is not working with the P9000.

I'm using Elephone original PE+ charger as you do and I'm using a USB voltmeter too, but the voltage never goes over 5V during a charging session.

I tought my charger was probably broken, but when I use it with a Vernee Apollo Lite, the charger goes up to 12V then 9V and so on until full charge.

Definitely, it's not a charger issue...

I'll be glad to check the difference between us to understand why my phone is not acting as yours.

Thank you for your kind help.
[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] JocPro:
I'm using the international P9000 ("Euro") version. The ROM is the official Nougat First Stable 20170418. I'm running Magisk 12 with MagiskSU with the SafetyNet module (Oneplus2: fix uncertified play store error v1)

Kernel Version is 3.18.35 from April 18 of 2017. Build version is Elephone_P9000_20170418. Security Patch version is March 5,2017.

The power meter is a cheap one from Aliexpress but re-reading the description in very broken engrish got me thinking... what if the power meter is forcing PE+? The answer is no. Tried charging a big powerbank and it charged at 5V with 1.6 A.

Another charger? Tried charging the phone via a generic Wireless Qi charger - still 5V but only 0.98 A.

Back to the phone, Factory Mode (Power + Vol-) charge test goes to only 4.8V and 1.2 A. Reboot the phone from Factory Mode, with the cable still plugged and after some 10 seconds of booting Wham! Charge voltage goes to 12V, current hovering about 0.8 A.

In the end, until someone with more hardware or more experience with these little power meters proves me wrong, I say that PE+ is working - with limited current, but working.

P.S.: I haven't tried with other ROMS. I think that in the weekend *maybe* I could do a full backup a give it a shot with CM13 and/or Eragon.
