Newcomer!

Hi, I´m a new and glad teclast p98 4g owner from Spain.

I´ve been following your developments on this questions. A little sadly, in the first place, because i found this when the order was done, but received them yesterday (2 of them, more data to gather :D), and found that mine had the deep sleep issue, twice. Ota was and is not working yet, so I started removing the chinese apps for optimization. Day was over, firmware downloading on pc for manual procedure, and this morning the deep sleeper was me, perfectly waking up, the tablet :). So I put my money on the chinese apps creating the issues. Also I came across another forum with other teclast tablet with different specs doing the same, on android 4.4.2 or 4.2, I think the circle gets narrower.

Mine came with dry battery, when it started i saw bluetooth on, so I´m guessing they left it on in the shop´s pre shippment chek, no worries. The other one came with battery at 70% and as for now is doing fine. No chinese things removal, no deep sleeping. Will tell you any change.

Aprox. 10% battery off in one hour series playback, max brightness, max volume (not too loud at street ussage, btw). A little slow charging, but I think that is just getting the pace. It´s a big one, nonetheless.

And last, but not least, taking in to account that I come from an ipad 1 wifi + 3g, this is just awesone, 32 gb, sd card, pendrives with otg cable, maybe external hard drive? have to try.., potential for android 5.x, and many more. Off course is not replacement for ipad air 2, but in my more than humble opinion, it gets damn close (for the price).

Summarizing: Good hardware, improvable software.

It´s a new model so that does not surprise me. In the meantime, I think it gives a good average user experience.

Just a thought, the more we have it, the more we encourage the company to upgrade and support it, no?

Hope my experience helps.

Will post any change.

Hi again.

I have been using it for two days and had the sleeping issue several times. First I thought it had something to do with wifi, as it would only sleep with it on, but today i saw the other i bought and was used by my mother without a issue. So, what was different? Me, as well as hendrickson, had turned on Airplane mode, as you can see on the pics in the first page. Logical decision if you still don´t have a sim to try 4g, trying to save some battery.

Made a lot of tests and it´s there: airplane mode + wifi= deep sleep, no matter time, seconds or hours. No airplane + wifi, perfect wake up, no matter time.

Confirmed in the two tablets i have.

Also found something about run time dalvik and ART in kit kat 4.4.4, beeing ART better and beeing used as default run time in 5.x. Allready changed, I think it runs better, but have no proof.

So, there you have it, I think is a minor bug with plane mode and wifi.

Hope it helps!

Can´t post screenshots

"Too young" member, can´t post links to screenshots showing my battery status with and without sleeps.

I feel tempted to spam 8 more posts to avoid anti-spam .... :D If someone wants to put them I´ll share the links.
[Android General] ippocampos:
I'll do it for you (send me email).

I really interesting about this tablet, but im not sure if its worth it ot buy ...or i have to search for another one like Onda V919 4G Air Octa Core MTK8752 9.7 Inch Retina Screen 4K GPS Tablet.What is your opinion???
[Android General] madhatterone:
re

Hi, I sent you the links, thanks again for your help.

About your question, seems to me that onda has taken good note of teclast´s work with this tablet, and made a model to compete, same hardware, same screen (¿4k?).

I see some differences betwen them:

- The casing: Onda´s has plastic in the corners, teclast´s has a full metal casing. My p98 already made a dive to the floor and only had a little mark in one of the corners. I´m not sure if it´s alluminium or an alloy, I have read both, but it´s sturdy.

- Fisical home button: It is what it is :laugh: Sorry, forgot to mention that only onda has it.

- Camera: Onda: 5mp, Teclast: 8mp More numbers doesn´t have to mean more quality, better wait for some upload..

- Software: Someone with more experience and knowledge could help with this, but, from reviews, videos and comparisons I have seen, I would say that onda´s SO, or Rom, seems better than teclast´s. As far as I´ve seen, they bring kit kat 4.4 (not sure) and 4.4.4 (confirmed), respectivelly.

Both of them are hardware compatible with android 5.x lollipop.

I´m always watching for updates and stuff even in chinesse and I did see today something about 5.5 in teclast. com. Not sure what it is or how long will take them to translate it, but seeing movement is a good thing. I hope that beeing "chased" by a rival makes them a little more competitive with updates. The english version of their home page seems outdated since 2014, not to much info there..

So the choice is yours, in my opinion, both of them are really good, two lollipops, different flavours. Once they run on 5.x, I think is going to be a estetics vs funcionality question. And price and abailability, of course.

Hope it helps!

[Android General] madhatterone:
Thank you

Here they are. The first two are with plane mode and lots of deep sleeps, and the other four, long periods of normal sleep and use without plane mode or issues. Remarkable thing is that without wifi, 3g/4g, bluetooth, when it sleeps, it drains no battery at all. If you let it at 71%, 71% you get hours later, nice.

And you ippocampos, have you decided yet?
[Android General] ippocampos:
Almost sure but still have some issues.....

Does it have gps?

Also do you know whitch is the difference with TECLAST P98 AIR Allwinner A80T?

can you suggest any store with good prices (i have found this 225$-10%=200$ if you take it from android app store http://www.banggood.com/Teclast-P98-4G-MT8752-Octa-Core-9_7-Inch-Android-4_4-Tablet-p-973198.html)??
[Android General] madhatterone:
Doubts

Let´s see if I can post a link, if not sending you pm.

Not working, I can´t fool the antispam.....

There you have a good technical camparison betwen the 2 mt8752.

Sorry forgot to mention the gps, working well in Spain.

The allwinner seems to be outdated, the models I can find have the intel baytrail.

Either way, it´s an octa ARM A53 64bits (mt8752) versus 4 A7/ 4 A15, 32 bits (allwinner).

Hey there.

I am just about to get a P98 tablet and I have been wondering about this 4G but the SW bugs are putting me off slightly....

Would you say (if you know?) whether the P98air (that use the A80T) is any better? I am not too bothered about the lack of a built in modem and the 5G wifi as I will mostly be using the tablet for video playback and I would put gizchinas custom ROM on the P98air of course as that seems to have fixed some issues... There are however not many custom ROMs available for P98 4G as far as I have seen...

Any ideas? Thanks

Hello. I just got a teclast p98 4g. I didn't succeed to upgrade the firmware 1.16 using instructions here 'techtablets.com/2015/04/teclast-p98-4g-rom-firmware-1-16-update/'or using archive from teclast web site.

I am running on windows 7. The flash tool doesn't seem to see the tablet when tablet is connected and is off and download can't start. (I don't see the chip info). I installed the pdanet driver. I also tried to read the PDF instructions....

How do you know that the tablet is correctly recognized? Can you sum up the instructions that you performed. Many thanks.

p98 4G Sp Flash tool NIGHTMARES!!!

I've been trying to flash RileyRom for my P98 4G (A8H6).

So far i've tried everything, read posts, forums, Tut, and random spelunking through google.

Tried MTKtools, ADB sideload, dissabled signature verification, installed all the VCOM/Preload and DA VCOM. Even if I do succeed to get the drivers installed and accepted, the SP Flashtool still wont flash. It will recognize the files, but I wont get any progress bar or error. :crying:

Tried multiple versions of SP Flash tool. Tried on Windows 8.1 x64 (HP laptop) and windows 7 x64 (Desktop PC) with all the same steps. I actually installed windows 7 just to see if it was my hardware. I tried with bare windows drivers, after no luck, updated my drivers with windows, and then the Motherboard release drivers.

But two completely different machines giving me the same issue. :mad:

I even tried my Linux Mint 17.1 but cant get it to recognize either.

So i'm wondering if its some sort of locked bootloader or a error in the code. Maybe its something completely different (new or different drivers?). :confused:

I would really like to get TWRP or CWM installed but I can't even get that far.

I'm stumped :eek: :( and have spent the last 4 days and nights trying to crack this problem.

I really wish Google made a mandatory Universal lib for all android devices running their OS so things could be ported easier.

choose Build(OS) + Manufacturer + Drivers (verify) = cook/compile or install ....what a dream :angel:

if anyone has any pointers or tips, i'm all ears. PLEASE!!!

Note: I can't even flash the stock 1.16 Firmware update due to this issue.

Hello I finally was able to update... The error was really stupid. You have to click download and then, only then, plug the telcast. Telcast has to be plugged switched off. The upload starts just after.

Hi guys,

I'm very interested of buying this table but i'm scared by the sleep issue. Is it solved by the last firmware update?

Thanks
[Android General] lore-mordred:
The issue goes away if you change the screen sleep settings and take off airplane mode... I don't have those issues anymore. Didn't have them in the first place until I reset my device. The update corrects it.

Beeping P98 tablet

Hi All

I have just received my Teclast P98 4G. I realized it has a silent beeping when I push any button, or start a program. Anyone experienced it? If yes, any solution? Thanks! (A similar problem can be found on youtube. Just search this: Teclast P98 4G annoying "beeep")
[Android General] lore-mordred:
Yes, I have this issue as well. It seems to be primarily a issue with the touch sounds. If you put the sound profile on silent or mute.... the issue goes away. With some audio there is no issue. But will come back if you hit a sound key or volume.

Seems like its a kernel or sound file issue in the rom. Wondering if a custom rom or kernel will fix it.

I just keep my volume muted for the android settings.
[Android General] Kollim:
It is a good idea to switch it off. Thanks!

However it is trange beeping, because it is not hearable with earphone.

If it is caused by kernel or sound file, isn't it necceary to hear it in earphone too?

(It is only logic, i am not an android "guru". ?)
[Android General] lore-mordred:
I haven't had as much noise with headphones either. As I read into it it also seems to be a grounding issue with the on-board speaker (back speaker and moatherboard wire). Maybe someone can do a tare down of their device and fix the speaker grounding wire... a video would help. Or a link for a DIY.

When I contacted the website support, I was told that they would credit back the price for a local repair. So I am assuming a local phone electronics repair place could do something, or local electrician. May have a easy fix as soldering or adding a grounding wire. Something like Galaxy S/ S2 antenna fix.

The tablet in itself is amazing. If a local Dev or Custom Rom unlocks this device, it is a master tablet. I haven't given the LTE radio a spin yet. Besides the sound issue, its a Monster!!!:cowboy::)

Trying to root Teclast P98-4G Lollipop

Hello,

Bought a P98-4G (A8H8), loaded with Android 5.0 Lollipop and a whole load of bloatware. Other than the limited cellular frequencies (it does not do 2G 850MHz and this is what my provider offers around my home, it is OK for the price I paid.

Unfortunately I have not been able to root the P98-4G, at least not completely, and I am still cautious and trying to backup IMEI, NVRAM, and everything else before wrecking it.

I found Vroot here on XDA and downloaded version 1.8.5.15285 with a little translation help from Google Chrome. It recognized the tablet, did some work, but in the end failed. A second and third attempt did not improve the result.

Was Hendrickson's P98-4G running Android 4.4 Kit Kat? It could also be that my different outcome is caused by an idiosyncrasy of my PC setup. My operating system is Xubuntu. I don't normally run Windows software and when I do I use a Windows 7 image provided by Microsoft in an Oracle VirtualBox. Everything played nicely, recognizing the P98-4G immediately, making installation of Vroot, and of PdaNetA4150 and its drivers a breeze.

Before Vroot, I attempted rooting on Linux. I found an su binary (su-new), connected the P98-4G to my Xubuntu, used adb to push the su binary it to the Download folder, gained shell root access, found that I can't change the executable bit on files in /sdcard but I can in other areas of the file system, and replaced the system's own su binary:

adb devices
adb push su-new /sdcard/Download
adb root
adb shell
mount -o remount,rw /system
mv -p /system/xbin/su /system/xbin/su-orig
mv /sdcard/Download/su-new /system/xbin/su
chmod 6755 /system/xbin/su

It is only partial and it seemed to be going well, but when I tried the new su binary:

error: only position independent executables (PIE) are supported

I guess that's Lollipop. I found many posts on PIE. I am still collecting the knowledge and trying to understand. The last time I cooked a ROM is more than a year ago.

Can't trust my current backup to be complete:

adb backup -all -apk -shared -system -f 150706teclast.ab

Replaying it after a factory reset put all my stuff back in place but does not remove some of the bloat I did remove.

adb restore 150706teclast.ab

I also tried MTK_root_update.zip and still have to analyze the resulting error:

Opening update package...
Error: Partition table not match
Update.zip is not correct
installation aborted

I'll have to analyze in more detail. Maybe on the weekend I will have time. In the meantime, I do not contemplate downgrading to the A8H6 Firmware. No newer firmware for A8H8 on Teclast's download page. I read about RileyROM. Anything else I am missing?

The bottom line is that I am not able to root yet, and any help is appreciated.

Thanks,

Yuv
[Android General] yuv4L:
You should be aware that there are two very similar models: P98-4G and T98-4G.

The merchants and even the manufacturers are quite sloppy with the published specifications. Depending on your circumstances, you may want to select the one or the other. If the intended use is on a cellular network, check against the local operators frequencies.

Also, depending on the use you are going to make of it, the following are details that may or may not be important to you:

Negatives:

The stereo loudspeakers position: aligned with the short edge. When watching movies in landscape orientation, the sound comes either from the left or form the right. Solution: bluetooth headset.

No vibrating ringtone possible. Don't expect discretion from this device as a phone.

No flash. Photo quality is anyway mediocre at best. If you are looking for a good camera, this one will not cut it. It is good enough for video conferencing.

Battery. Watching DVD quality H.264 encoded movies at middle brightness it barely last past three hours.

Positives:

Sturdy case. I bought this for a kid and am less worried about the occasional drop on the floor than with flimsier cases I have seen in the past.

GPS is fast and picks up signal much better than the other MTK-based gadgets laying around here.

The display is very comfortable for indoor use, with a wide dimming range that makes it a comfortable bedtime and daytime reading. I have not tested it outdoor in bright sun yet.

Microphone and speakers. I tested VoIP calling with Linphone and the quality was good enough to leave the tablet in the middle of a board room table and hold a conference call.

The weight of all of these factors depends, of course, on your circumstances, needs, and intended use.

For me, the biggest negative of all those Chinese gizmos is flaky support. Manufacturers and suppliers are more interested selling the next piece of *c* instead of supporting what they have already sold. For lack of software update, the devices become obsolete on security grounds, which is usually earlier than ageing-grounded obsolence. A Google Nexus might cost 3x more, but it will be supported 3x longer and with the source code freely available, users can self-support until the useful life of the hardware has been fully exploited.

Teclast P98 A8H8 Android 5.0 Lollipop

Hello everyone.

I have the Teclast P98 A8H8 with Lollipop too.

How is your tablet? My is slow for a 8 cores 2gb RAM tablet. :confused:

I have something about 400 mb of free ram and the rom is generally slow.

Do you think is a software problem or a hardware problem?

Did you ever tried Lollipop 5.0 on H8A6? If you did, how did it go?
[Android General] lore-mordred:
I had a similar issue. I'm not in lollipop but I noticed that iPhone headphones don't fully work on this tablet, but some larger stereo headphones I have work. So you may need to change to a basic aux jack, one with less functions perhaps out get a adapter.

It seems to be registered to the way the aux jack is composed.

Android 5.0, rooting, ...

Android 5.0 Lollipop ROM 1.04 can be download from here: pan.baidu.com/s/1qW0zMGk

(I'm sorry I cannot post links here since this is my first post, just put the http url stuff in front)

The "download" button is the one with the downwards pointing arrow saying "下载(595.9M)". Don't touch anything else or you will land in some kind of chinese Nirwana ;)

There is also a link to this on the offical chinese Teclast site (not on the english translated pages) but I couldn't find it again.

Rooting:

Since my previous attempts to create a working custom recovery failed I rooted manually through adb.

This works since root access from adb is enabled in the ROM. Just do "adb root" or call "su" from an "adb shell".

What you basically have to do is to remount "/system" in "rw" mode and follow the instructions given in the latest SuperSU (2.49 BETA) "update-binary" script.

I would create a "su.orig" from the original su to be able to use it from "adb shell" if anything goes wrong. Make sure it has the same access mode and Selinux context as the original "su", you can use "chmod" and "chcon" to accomplish that. Maybe just a "mv su su.orig" will just work. I used "cp" and had thus had to restore those things afterwards.

After rooting you should also apply an SD-FIX (just google it, you can do it manually by editing "/system/etc/permissions/platform.xml") to enable the root user to write to the external SD-Card which becomes handy e.g. with Titanium Backup.

The same way you can install e.g. Xposed framework or Viper4Android. Just unzip the flashable zip and do the stuff that's in the respective installer script by hand from the rooted adb shell.

Btw, F-Droid more recent than v0.83 will only work on this Lollipop ROM after you have installed Xposed.

Of course you can also modify the "system.img" from the stock ROM and include those features directly into it and reflash it using SP-Flashtool.
