[Asus Zenfone 5Z  Questions & Answers] fundo81:
Until 3 days back, the Asus 5z (Non-rooted) was charging fast with Original Asus quick charger. But then it got FOTA update to ww_ZS620KL_90.10.138.181_20190202

(build number: PPR1.180610.009.WW_user_90.10.138.181_20190202)

(Baseband ver: M3.15.35.23-Draco_000621)

After the update, there is a weird behavior seen while charging. After charger is switched on, charging go upto 1580ma (measured using "Ampere" app) and then gradually, the charging gets reduced to 680ma-720ma within next 4-5 seconds and then the phone charges constantly at this speed. If i switch-off the charger and then again switch it on, then again the charging go upto 1580ma, then to 700ma. Now it takes 150min-180min to fully charge the phone. Earlier it was just 100min at ~2500ma speeds.

Its like there is some kind of capping enabled via this FOTA update, which is not allowing fast charging. As soon as the phone detects fast charging, it reduces it to normal speeds, due to some unknown reason.

Charger is not faulty, i have checked it using Original Asus charger, Tronsmart QC3.0 , Poco F1 original QC3.0 charger, Motorola original QC2.0 charger. All yields the same result, It goes upto 1580ma and then reduced to ~700ma.

Things i've tried:

Enable/disable AI charging

Rebooting

Different chargers/Different electrical sockets

Discharging completely and then charging

Things i've NOT tried yet:

Battery calibration (don't know if it will actually works)

Factory reset (have a lot of data to backup before doing so)

Do you think the issue is related to January security patch? My phone is not rooted.

Please Help.

Mines still fast charges but I notice it stops fast charging at 70% instead of 80 with ai charging on

Yes i have also noticed this...its taking almost 3 hrs now....after the update... seriously asus all software updates were crap... ?

No Bro, no reply from ASUS forum too. Since many of us are experiencing this issue, i hope ASUS may resolve this in their security update.

same issue, powe off phone before charge and power on during charge let the phone charge at fast charging speed but this is very inconvenient
[Asus Zenfone 5Z  Questions & Answers] nadeem1991.na:
I also facing same issue but when I reverse the type C cable sometimes it charges fast.

May Asus solv it
[Asus Zenfone 5Z  Questions & Answers] Evil Eye:
Many people are facing the same and have reported it in Zentalk forums.

I request you all to report it too so that it comes in the notice of asus devs and they fix it asap.

[Asus Zenfone 5Z  Questions & Answers] babaibhat:
I believe this is due to loose connection or lose contact in wall socket. I have seen, if you remove the wall socket and then reattach again, it charges fast.

Maybe it detected some sparks/surges in USB output and kept going to safe mode.
[Asus Zenfone 5Z  Questions & Answers] geekdeepak:
no that's not the case. Many people has reported it already.
[Asus Zenfone 5Z  Questions & Answers] Chavinash2004:
Hi All,

I too facing the same problem and complained in ASUS twitter site and they told to go to the Service Center. If i restart the phone before charging then my phone is charging fast.
[Asus Zenfone 5Z  Questions & Answers] nshreenath:
I too have this problem. I use this workaround.

Connect the charger to the phone and let the current reading come down in the ampere app. After that, keeping the charger connected, restart the phone. You'll see that now your phone is fast charging. The current goes up to 2500 ma now.
[Asus Zenfone 5Z  Questions & Answers] ranajitojha786:
Then you mean Every time I chargey phone I have to restart? What kinda solution is this?
[Asus Zenfone 5Z  Questions & Answers] geekdeepak:
issue fixed with the 92 mb update i got last night
[Asus Zenfone 5Z  Questions & Answers] Mustajab Is'haq:
For me the 90mb update reversed the charging speed. The update prior to this update fixed fast charging for me, but after this 90mb update the phone stops fast charging at 70%. I measured the time it takes to go from 6% to 100% (with AI charging ON), it took about 1 hour and 15 minutes. So it doesn't bother me that much as it's still plenty fast for me. I hope Asus fixes the issue permanently.

Given high popular demand for Fire TV stick 4K unlock, there is now a separate thread in the appropriate FireTV location:

https://xdaforums.com/fire-tv/general/please-donate-to-k4y0z-bl-unlock-twrp-t3913935

March 24th, 2019 post

The HD10 2017 fundraising effort had been a huge success, and [MENTION=7104332]k4y0z[/MENTION] had delivered an unlock for the device - link. Many thanks to everybody who contributed funds to the undertaking!!! Enjoy the unlocked device! Custom ROMs will be forthcoming!

Now, given that a few other devices don't have an unlock yet, we shall keep this thread open as a place to express those wishes. If the wishes are matched by funds, [MENTION=7104332]k4y0z[/MENTION] may spend a bit of his time to acquire the requested older device on eBay, and unlock it ;)

At present, there is quite a bit of interest to support HD8 devices. Chances are if [MENTION=7104332]k4y0z[/MENTION] acquired one of HD8 devices, he would be able to support all vintages (2016-2018). Let's make it happen!

March 5th, 2019 post

Update: We need to secure sufficient funding for [MENTION=7104332]k4y0z[/MENTION] to acquire an HD10, and work to unlock it! The donation PayPal account is in his profile. Given [MENTION=7104332]k4y0z[/MENTION]'s excellent track record in unlocking, the delivery of HD10 unlock is not in question !!! :D

For my own very selfish interest, I have the oldest bootloaders known - 5.5.0.0. As such, I want a purely dd based method, where the exploit resides strictly within the official boot0 region, which would be no more than 1 Mb :D
[Fire HD 8 and HD 10 General] k4y0z:
I would rather use the newest exploitable LK to ensure compatibility with the newest boot-images.

The HD10 forces 64-Bit kernel which makes the exploit more difficult and also requires repartitioning the device.

This would also mean decreasing the size of userdata-partition by about 110MiB and an increased boot-time of about 10 seconds.

It also requires a factory-reset since userdata needs to be reformatted.

I actually have a working exploit for another device that also forces 64 bit, so I know it's possible.

Unfortunately I don't own a Fire HD10, which I would need to work on it.
[Fire HD 8 and HD 10 General] bibikalka:
Do you care to set up an account on GoFundMe or Fundly? They will eat about ~10% of donations for processing. Once a few people pitch in a few bucks, you could purchase a device or two.

Fire HD 10 is a pretty capable device, so needs some good software as well! There are also a few Fire models that are totally unloved (HD6/7 2014, HD8/10 2015) - those could use some BootRom hacking too ! :D
[Fire HD 8 and HD 10 General] dbnaruto:
Heck, I'm so impressed with how easily for my Fire 7 unlocked, that if one of the people who got the other Fire tablets unlocked commits to getting the Fire 10 working, I'd just buy them the refurb'ed tablet to work on. It's what Amazon wish list are made for ;)

[Fire HD 8 and HD 10 General] bibikalka:
There is a German PayPal email in your profile, would you be interested to work on this if you got an HD10?
[Fire HD 8 and HD 10 General] DragonFire1024:
I have a few HD 10s with plans for another. I need mother nature to cooperate with me for at least two days and I can build and compile the fastboot binary for the mt8173, it at least try. Yes mediatek has their own binary, their own command line for it. The structure is not much different from ADB, and I'm not sure amazon even knows it exists. I'm not even sure if any of you knew it. If I or anyone else can build it, all we need are the mediatek drivers we use currently to get to bootrom, and the binary to run the commands and we're in.
[Fire HD 8 and HD 10 General] DragonFire1024:
P.S. I have seen echos of fastboot being used to flash images. We know that's not possible as the current setup stands. So if my research in the past year was at all right, then we can use the kit I have to build and sign factory images (with official tools and official signatures included), to our hearts content. It just so happens I have the kit with everything needed to do just that, including the source code to the bootloaders and kernel (mediatek) as well as other proprietary things. We just need to get.this fastboot built.
[Fire HD 8 and HD 10 General] DragonFire1024:
Having trouble compiling the binaries. This is my first time using gcc. Here is the link to the stuff the mt8173 needs that's we can build. If you click the bootloader/lk link then bootloader, lk, app and mt_boot, you'll see fastboot, mt_boot, the command lines etc. https://github.com/Goayandi/mediatek_mt8176_development

Also in the platform folder in bootloader, lk, target, whiskey, Inc, is a hex OEM public key the private key verifies. https://github.com/Goayandi/vendor_...p-7.0/bootloader/lk/target/wisky8176_tb_n/inc What do we need to don't format this key into a bin file we can flash in fastboot?
[Fire HD 8 and HD 10 General] Agrajag27:
I donated, so I'd clearly love to see this happen. Best of luck guys.
[Fire HD 8 and HD 10 General] GuyInDogSuit:

Thanks everyone for your donations, especially [MENTION=2382323]dbnaruto[/MENTION] for your VERY generous donation!

I nearly got the funds together, so I went ahead and ordered a HD10.
[Fire HD 8 and HD 10 General] DB126:
Although I don't (yet) use your exploits and will likely never own a HD 10 I tossed in a few shillings as a token of appreciation for all you have done. Hopefully will help close the gap on your recent Amazon acquisition. :)
[Fire HD 8 and HD 10 General] bibikalka:
Excellent!!!

I say we shall keep going ! There are other Fire devices out there that need some loving & TWRP!

Any nominations for other Fires amongst XDA frequent flyers? Shall we set up a poll? Fire stick 4K? Fire HD8/10 2015? What should the additional funds be collected for?

[MENTION=7104332]k4y0z[/MENTION] - HD10 2017 is a nice device, hopefully, you can do your hacking without opening the case! Please put exploit at 512k in boot0, this way we can dd everything in!
[Fire HD 8 and HD 10 General] obvious:
Would HD8 2017 be a suitable candidate?
[Fire HD 8 and HD 10 General] bibikalka:
Sure! Donate a few coins ! :D

Btw, it's almost done, given it's the same chipset as hd8 2018:

https://xdaforums.com/hd8-hd10/orig-development/fire-hd8-2017-amonet-debrick-root-t3897841

But putting things together competently will still take effort. That's why you want [MENTION=7104332]k4y0z[/MENTION] to have funds to purchase the device!
[Fire HD 8 and HD 10 General] DragonFire1024:
I've been trying to build the mt_boot binary separately. It doesn't look like it's going to happen. Even if I can, the source isn't properly formatted so the compiler can't detect the files the scripts call for. So I have to rebuild the directories and put the files where they belong. If I don't do that, then I will have to rebuild the scripts...all of them. And that is going to take a lot of time. If that doesn't work, then it would mean rebuilding the LK from the source. But we can't flash a working LK, unless it's stock.
[Fire HD 8 and HD 10 General] GuyInDogSuit:
Lean Kernel?
[Fire HD 8 and HD 10 General] DragonFire1024:
I'm sorry I don't understand your question. If you are referring to what LK is, it's supposed to mean Little Kernel. However, I don't know if it's pieces of hardware, but I have found serial numbers in the LK (one of those like minded partitions), that traced back to a Lenovo Kernel. I would have to try and find them again, but I did make a brief post about it somewhere between the couple of threads talking about unlocking.
[Fire HD 8 and HD 10 General] obvious:
Little kernel
[Fire HD 8 and HD 10 General] DB126:
Why are you hijacking this thread with your own woes? Title suggests this is about collecting funds another member to tackle the task you struggling with. If you have something to contribute to that effort (funds, knowledge, sources) please do so.
[Fire HD 8 and HD 10 General] DragonFire1024:
Apologies. But the original title and basis was discussion of the topic of unlocking this device.
[Fire HD 8 and HD 10 General] DB126:
Focus has (apparently) changed. There are other threads dedicated to general bootloader unlocking. Probably best to continue discussion there.
[Fire HD 8 and HD 10 General] laidbackcloud:
Hey everyone,

So what's the status on fire HD 10? Is it being worked on? Nothing about it has been posted for few days. Hope everything is ok!?
[Fire HD 8 and HD 10 General] bibikalka:
At the moment, [MENTION=7104332]k4y0z[/MENTION] is working on HD10. Unlocking HD10 is a bit more involved, it appears it would need shrinking /data by ~100 Mb, and then creating a couple of additional partitions behind /data. For convenience, it may be of value to try to port the /system located TWRP to HD10 as per this FireTV method by [MENTION=3991724]rbox[/MENTION] ( [MENTION=3497316]retyre[/MENTION] ?):

https://xdaforums.com/fire-tv/development/firetv-2-recovery-t3309780

(any itchy developers out there up for the task? in case of a failure one would only have to sideload a fresh ROM and get temp root via mtk-su)

Anyway, please feel free to donate to [MENTION=7104332]k4y0z[/MENTION] in order to raise funds for other devices listed in this thread!
[Fire HD 8 and HD 10 General] DragonFire1024:
I may be willing. I'll need instructions. There is a TWRP build for the HD 10 already so that's not an issue.
[Fire HD 8 and HD 10 General] bibikalka:
Sure! Feel free to try to get this working! If you succeed, there will be a simple and safe TWRP way to shrink /data and reformat to accommodate the full unlock!

Rules of engagement:

1) Start a brand new thread for your effort

2) Minimize questions to [MENTION=3991724]rbox[/MENTION] and [MENTION=7104332]k4y0z[/MENTION] and other developers as much as possible

Original pointers from FireTV2, basically, you need to reverse engineer this approach and apply to HD10 (everything you will need is in these threads):

https://xdaforums.com/fire-tv/orig-development/firetv-2-recovery-installer-t3309785

https://xdaforums.com/fire-tv/development/firetv-2-recovery-t3309780

https://xdaforums.com/fire-tv/development/firetv-2-sloane-prerooted-stock-images-t3309783

For reference, Fire TV 2 has MT8173C, while HD10 has MT8173. So the chipsets are practically identical. There could be slight differences in FireOS, but both devices still use Lollipop, so there is a good match there.

Some words of wisdom on how to load TWRP from /system (with some clarifying edits of mine):

These days mtk-su root is so quick, that a few sideloads during the development (& bricking) may not be too time consuming.

[Fire HD 8 and HD 10 General] DragonFire1024:
I looked at the Amazon kernel source and the file folders say mt8173B. Not sure if that's a fluke if amazon just doing their move around or if that's an official designation. I'll look over everything in the next day or two. However I won't be able to do much until mid week when I have my two days off work.
[Fire HD 8 and HD 10 General] Murcielagoz99:
Hey guys, I've been looking into this for a while now and have practice in reverse engineering and have worked with lk's before. I currently own a fire HD10 (7th gen).

https://xdaforums.com/fire-tv/general/please-donate-to-k4y0z-bl-unlock-twrp-t3913935

It's actually quite rare when with such a relatively moderate level of donations we can achieve so much !

[MENTION=7104332]k4y0z[/MENTION] lives in Europe, and Amazon devices seem to be quite a bit pricier over there. But still - we can overcome that with some purposeful crowd funding.

I have an extra HD 8 7th Gen (2017) motherboard and battery I'd be happy to send you if that would help. When we were doing the hardware rooting I thought I broke my original board so I ordered one with a shattered screen from eBay but then revived mine.

Let me know.

ps. After connecting the battery and powering on the board responds to adb commands as if it were a complete device.

There's nothing yet for the bootloader unlock.

And I agree, I'd be interested in helping the cause as well. I imagine plenty of others feel the same. It's the last of the recent bunch without an unlock.

Plus, Lineage 14.1 could likely be ported from the 2018 HD 8.

Is the bounty completely over? Or is there still an active one for unlocking the HD8 2017?

It would be amazing if you can figure out a bootloader unlock. I guess there are more differences than I thought between the 2018 vs 2017 HD8... Unfortunately, I am stuck with two of the older models that I was planning to wall mount in my home, but the old webview that fireOS uses many of my home assistant cards are broken...

My HD10 with lineageos is working great though and I would love to give the HD8 the same treatment.

Hi guys,

I got my OP6 from a friend who has lost his original charger. I didn't have any issues charging it with Anker (https://www.amazon.com/gp/product/B016LO4UTA/ref=oh_aui_search_asin_title?ie=UTF8&psc=1) as it was done pretty quickly. Do I really need to buy the official version of the charger to get better performance ? What do you all recommend?

Currently there are no deals running for OP6. Speaking of the official charger, it is pretty expensive ($33.15 for 100cm & $37.90 for the 150 cm)...ouch!

So please advice me, i really appreciate it!

Many thanks! :D
