So I got a tablet for free: Allview 3 Speed Quad HD (specifications)

When I received it someone tried to install another ROM to "update" it, but the wi-fi wasn't working anymore, which probably means it was the wrong ROM for it. I tried finding the stock ROM for it, but ended up only finding an update for the stock ROM, not the ROM itself.

Contacting the Allview company, they told me they're not making public the stock ROMs anymore, the only way to get it is to go to their service and pay them for the reflash. I would do this, but I'm not in the country anymore, not even on the same continent.

So apparently this Allview company tends to clone cheap tablets from China, then make modifications and ROMs for them, so I ended up flashing a ROM for an Onda v975s tablet, which was the only ROM that I was able to flash successfully, but the wi-fi still wasn't enabling. Everything else pretty much works and performance is actually pretty good.

Apparently this tablet has a very rare wi-fi chipset, because Onda uses another chipset on their tablets, so I assume Allview changed it.

So I opened it up and took some pictures, maybe this could help me identify what wi-fi drivers this ROM could need?

Someone was saying that the only way to get this is to find another tablet like this with working wi-fi and extract the wi-fi driver/source code or just copy that entire ROM. Is that the only way? Because that's pretty unlikely since this is a pretty old piece of hardware.

So, does anyone have any idea if this is solvable or should I just give up? I'm a complete newbie, I only know the basic of flashing/rooting, so I apologise if this was a stupid thing to do. But I honestly don't know where else to ask about this. I know it's a long shot with these ****ty cheap tablets.

Please tell me if I should provide anything else.

Cheers
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
I recently pulled the trigger on the MPHS25.200-23 official Android N software update for the Moto X Pure Edition. Aside from the concerns I listed among the release notes in the rollout discussion thread, I have been reasonably satisfied with the update. However, battery life absolutely plummeted after installing it. A hard reset was executed before (and after) the update and a cache/dalvik/art wipe was completed a couple days after getting everything set up.

Battery percentage drops at record speeds while the screen is on (although standby time is still okay). Using a Nexus 6 for reference, I compared results using Ampere and didn't notice any significant difference in power use (at least while idling with the screen on). Using the CPU usage monitor tool found under the debugging panel, nothing seems out of the ordinary here either (idling and light use shows a figure in the 9s, typically).

At this point, I figured misbehaving software could be ruled out, so I turned my attention to the battery. On my laptops, I can use either the OEM's power manager application or a Windows commandline tool (in Windows 8 and newer) to generate a battery health report, showing the "design capacity" and the actual "full charge capacity" in mah, which is a very good indicator of a battery's health. I struggled to find an equivalent to this on Android, but, after some digging, did find some promising leads

The trouble is that the results aren't consistent. On the Nexus 6, running "dumpsys batterystats | grep "Capacity"" shows a "Capacity" of 3220, which just happens to match the design capacity of the Nexus 6's internal battery. Running "dumpsys batteryproperties" shows "2910000" at the bottom next to "Full charge." Since the Nexus 6 is close to 3 years old now, it would make sense that the battery is only good for 2900 mah. Everything makes sense so far...

On the Moto X Pure Edition, however, "dumpsys batterystats | grep "Capacity"" yields a puzzling "Capacity: 1948." "dumpsys batteryproperties" yields "Full charge: 1948000". This makes no sense. If "Full charge" represents the design capacity, (not taking usage into account) why would it show as only 1948 on the Moto X?

Now, I'm opening this up to the community. What do you see when you run the first command?

dumpsys batterystats | grep "Capacity"

Do you see the expected design capacity of 3000 or do you also get a small (or smaller) number like I did?

Either way, I'd like to see people's results for the second command as well:

dumpsys batteryproperties

How close is the resulting "Full charge" value to the rated 3000?
[X Style (Pure) Q&A, Help & Troubleshooting] autosurgeon:
The battery never was a 3000mah. That was a lie.

Have you done a factory reset since the update?
[X Style (Pure) Q&A, Help & Troubleshooting] roozbeh101:

although my battery misbehaves big time ! from full charge to 80 in less than 10 minutes.
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
Thank you for the input

I figured as much, but not a value nearly half that! Definitely performed a hard reset, both before and after the update.

Interesting. This is more in line with what I was expecting to see on my own system, although it's surprising to hear that your phone still misbehaves as it does.

Going to try battery replacement

At this point, I'm going to chalk the issues up to a failing battery and simply consider this a coincidence. Does anybody who has done a battery replacement recently recommend any good brands or vendors who sell a decent battery that I won't have to bend to make fit? One eBay seller who I have contacted says that he normally sells the flat ones, but will provide a curved battery in its place if the customer specifically asks for it at checkout.
[X Style (Pure) Q&A, Help & Troubleshooting] roadrun777:
It may not be a bad battery, as I had the same issues and I recently replaced my battery with a battery the seller swears is brand new, and again it is behaving exactly like the old battery.

So I am at a loss as to what to try. How do you fool the system into thinking the battery is brand new?

I just decided to check the dumpsys batterystats and it shows absolutely nothing

dumpsys does not give me any information at all, is this a permission problem?
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
The plot thickens...

Interesting. What time of runtime (screen-on time) are you seeing? Do you remember what seller/store you got the replacement from? Was the replacement flat or curved, like the original battery?

Don't try "dumpsys batterystats" without the "grep "Capacity"," else you'll get so much output that the device might freeze and then reboot.

The fact that you're getting no output with either command seems unusual though. I don't know if it'd make a difference for sure, but, out of curiosity, do you have busybox installed?
[X Style (Pure) Q&A, Help & Troubleshooting] roadrun777:
Yes I have busybox installed, let me go check version.

busybox 1.27.2

I thought maybe it was because I was plugged in but I installed a terminal app get root and check it internally without it being plugged in and nothing, there is absolutely no data.

So I am at a loss as how to fix this. Something is either hijacked the system and is hiding the data or there is no data and the processes that create it have not run correctly, which then means I will have to hunt down exactly what processes create the info.

Any help would be appreciated as I've been doing stuff like this without help for decades and it gets very time consuming to track down bugs for developers that are too busy driving around in their humvee's and flying to Europe to care.
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
Strange output; are you running the stock rom?

That's really weird that the command takes, but displays no output. My Samsung Epic (with a CyanogenMod build of Ice Cream Sandwich) simply scolds me when trying to put the commands in. The only time when I can achieve no output (on the Pure Edition or Nexus 6) is if I forget to go root before typing the commands. Are you on the stock rom?
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
No good, it seems

Well, I received the replacement battery today and installed it. To my surprise, however, there was almost no measurable change in runtime; I charged it up and burned down half a tank with only about 45 minutes of screen-on use! I ran those commands again, and this time, both values indicate a touch over 3000. I'll give it a few cycles to see if things return to normal, but if not, then I'm at a loss. Are there any negative consequences to "downgrading" to Marshmallow?
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
Unusually high power draw spotted, as reported by Ampere

Quick addendum: I tested again using a program called Ampere, and found that current draw is actually a bit on the high side. Comparing alongside the (nearly identically-configured) Nexus 6, using multi-window, I found that current draw is actually often doubled, and sometimes even tripled.

For example, when playing an HD YouTube video, the Nexus 6 maintained a draw of around 330, give or take a few dozen (fluctuating between around 300 and 430). However, the Pure Edition was between 800 and 1400, typically settling at around 1100 to 1300. Thinking that there may be some kind of software issue after all, I rebooted into "Safe Mode" and tried using the device that way, but saw no perceptible change (at least as best as I could tell without being able to run Ampere).

With that in mind, I'd like to pivot more to a discussion of what kind of power draw everybody is seeing in Ampere under light usage and video watching, regardless of what Rom or kernel you're running. Is anyone else seeing high power draw while doing relatively little?
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
200-22 was the ticket!

Well, this will be the second time that a weird, untraceable issue wound up being solved by flashing back to stock and upgrading. I installed that 200-22 factory image, took the new update, (October security level) and everything appears to be fine and dandy once again. Runtimes are much better and Ampere reports much lower power consumption (idling below 250ma and light use in the mid-to-low hundreds; which is much less than half of what I was seeing before).

Idle power draw (prior to restoring most of my apps) was holding steady at around 1.4% per hour, averaged over about 24 hours of non-use. And that's without any of the Amplify or Greenify tweaks.

I'll have to withhold final judgement until all of my data and software is restored, but things are looking really good so far. That "Sprint" factory image appears to have saved this Verizon-network-user's bacon.
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
Update...

Maybe that wasn't it after all. Battery life started tanking again within a couple of weeks after the operation, so there must be some software I'm installing that isn't playing nice somehow (even though Wakelock Detector shows no noteworthy periods of unrest). It's odd because I have almost the exact same software load on my backup phone (the Nexus 6) and can leave that thing in the backpack for days on end without it losing much charge at all, while the Pure Edition is managing to run down at a rate of about 4 percent per hour, screen-off and unused.

While the device is awake and running, Ampere shows an idle power draw of between 450 and 1000 mah, which, while (probably) not as bad as before, is still consistently higher than it should be.

The silver lining to this whole thing is that I now have so little time in the day to actually use the phone that it usually doesn't matter. If I get the chance again, I might switch back to the Nexus 6 temporarily again to troubleshoot the Pure Edition more carefully. There has to be something that I'm missing.
[X Style (Pure) Q&A, Help & Troubleshooting] hagi_mostafa:
same issue here after updating to NPHS25.200-15-3, i have to charge the phone almost twice as before. looking at apps usage shows nothing unusual. i'm checking battery performance using accubattery:eek:

[X Style (Pure) Q&A, Help & Troubleshooting] hagi_mostafa:
Check these two shots
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
Going to have to find the answer the hard way

Are you running stock rooted? At this point, I'm beginning to wonder if I got a bum replacement battery, since the whole thing just shut down spontaneously on me one day at around 20%. I'll try switching back to the Nexus 6 and start over with the Pure Edition again, this time installing things one-at-a-time (or in waves while making liberal use of backup images) to see what (if anything) is not sitting right with it. The most perplexing thing of all is that I have the Pure Edition configured almost identically to the Nexus 6 in terms of tweaks and software, and yet the Nexus lasts 2-4 times longer.

Even right now, I'm sitting at 4% with about 32 minutes of screen-on time and 36 minutes of background audio playback over about 12 hours. In contrast, the Nexus 6 is at 74% with just over 1 hour of screen-on time and 52 minutes of screen-off audio playback (and yes, I do have an active Sim card installed in it too, albeit on a different carrier). In essence, the Nexus managed to do twice as much with one quarter the power draw, so I know for a fact that something is wrong, either in hardware or in software, and my experiments over the course of the coming weeks will confirm, one way or another, which is the case.

This whole experience really has soured my whole opinion of this phone. I still believe that it's one of the best smartphones ever made, but there's no doubt that it has a serious problem, and I'm disappointed by both possible outcomes. If it ends up being software, then it'll be plain that Lenovo screwed up in a big way to make it so that I could duplicate the same weird bug twice in a row with a fairly common/minimal setup that should not cause any problems. On the other hand, if it ends up being hardware, then that'll be the end of the line for this phone, plain and simple, seeing as few of the available battery replacements don't completely suck. Honestly, I'd have replaced this phone sooner, given how much time it's cost me, but there's just nothing affordable I could go to that wouldn't be a compromise. I guess the dream of "decent smartphone" just wasn't meant to be for any longer than that first year :(.
[X Style (Pure) Q&A, Help & Troubleshooting] hagi_mostafa:
after several cycles accubattery shows that a full battery just works no more than 3 hours. in some cases it even lasted for just one hour or less!

so of course there's something wrong here.

the issue has appeared exactly since i upgraded from 6.0.1 to version 7, both official xt1572 asia ds. just flashing boot and system files. no root custom recov or else.

so i really doubt that this could be of a hardware failure. also i'm using the same collection of apps as in rom 6.0.1 so this is not an app issue.

as accubattery shows battery health and power usage, battery health is 80% at 2580mah and power usage is high, something between 500 up to 700 mah.

the only possible cause resides in rom or flashing. i'm gonna try flashing us rom and if the problem continued, i'm gonna flashing latin ds with boot system and modems.
[X Style (Pure) Q&A, Help & Troubleshooting] Bill720:
Gratitude for the information

Good to know. Mine is the North American XT1575 variant, but I'm in the same boat otherwise. The trouble seemed to start almost immediately after installing the new 7.0-based update, so there's a good chance that it's related to this in some way. Mine is rooted, (stock rom/kernel, however) but it's good to know that somebody running stock is seeing the same thing.

I don't think that it has anything to do with the software region. I'm on the standard North American build with the same problem, so the issue (if in software) must be a broader one. I'm going to try to switch back to the Nexus 6 today so that I can start the long process of starting over on the Pure Edition and getting to the bottom of just what causes things to crash & burn.
