I guess this is something you might have to test yourself. There is as many opinions

about the tweaks as there is those trying them. Sometimes benchmark apps say

that there has been improvement but the feeling is the opposite, and sometimes its

other way around. Also people value different things.

But the tweaks aren't my thing really. Very few actually work, IMO..

And not necessarily because of them being totally wrong but the tablets differ

and therefore the coding is also wrong, paths differ and also native programs.

The only tweak I have made was the boost patch, and I made it only because

Kernel Tuner didn't work in the newest firmwares at that time.

Anyway let those speak who maybe have tested tweaks more than me...

All these bugs are totally contrary to my experience. I've had no battery issues at all with mine, and in fact the only thing I think could be improved (given the hardware) is the auto-rotation. Of course I am not using [MENTION=4218632]steve30x[/MENTION]'s repartitioning, just his port of C. Troy's AOKP ROM. And I installed it with CWM only. I have to think one of these things must make the difference. There was another member who had similar results to mine, somewhere in the middle of this thread, but I'm too lazy to dig for his comments.
[General Questions and Answers] steve30x:
I tried it on the T71 but it didn't help. I flashed it on my new tablet and it makes a big difference. My battery lasts a whole lot longer and apps load faster.
[General Questions and Answers] dr_bowtie:
I flashed the wacelock fix CXZ posted and I am not sure if that fixed the issue or it resolved itself. Common sense would tell me that when a device is powered OFF it should use NO battery and should remain in the last charge state. When I flashed CM 10.1 through CWM it had pretty rapid battery drain and even when fully charged it would drain about 10% an hour with WiFi OFF. charging it and turning the unit OFF and checking it the next morning it would not even power on the battery had drained so much. Other than the battery drain issue in CM 10.1 it ran pretty flawless (other than the browser being very laggy).

Installing AOKP through CWM sort of exhibited the same issue but not as pronounced. I could charge the battery and it would drain but over night it would still have 70% battery just sleeping. Charging and powering off the device it still drained battery but I could power it on and charge it. Now the next cycle of charging and powering it OFF it still had full battery the next day and has since.

I probably should have tried CM 10.1 a few cycles to see if the drain fixed itself or there was an issue but, AOKP doesnt do it especially since I flashed the wakelock fix. But after 4 days its dead.
[General Questions and Answers] kevinthefixer:
As I think I said in an earlier post, I ignored mine for a good long while, maybe a month--and still had 100% battery. I don't think I'll be changing ROMs anytime soon, I like this one.
[General Questions and Answers] dr_bowtie:
just seems weird it sat in a cabinet for months on end and held a charge but after flashing the rom a few times wont hold a charge more than a few short days. took over 12 hours to charge about a 1/4 charge. I think the battery is giving up the ghost. and it's had less than a dozen charges.

Hi man, long time no talk, have an issue to see if you can help me solve it, here is the deal, my friend finally brought his Hanspree for repairs after all this time, 2 day ago he told me the tablet turned off itself while he left it charging, now it won't boot, if you turn it on normally you can see the screen turn on the backlight but nothing else happens, not even the logo shows up, if I boot into CWM recovery with volume down and power I see the Hanspree logo and it enters the recovery, BUT, I can't move in it and looks weird (see the attached screen), volume buttons don't do anything so the only option I can select with power button is restart.

If I power up into download mode I get the item in the device manager (worked on a Win 7 laptop, failed to install drivers in XP or Win10) but ADB can't see the tablet in any way, no devices attached.

I ran out of ideas on what to try to do to revive it, I'm all ears for suggestions, thanks. :fingers-crossed:

Update:

Told him to let the tablet drain the battery and then try to boot it again, miraculously it worked!
[General Questions and Answers] dr_bowtie:
Today I decided to flash the stock recovery and the latest stock rom. For anyone considering Rashr will flash recoveries and works well on this tablet. Flashify would not.

I could have loaded the Pad Tools and hooked it to the PC and did it that way but I just couldnt bring myself to spend 20 minutes doing all that when I did it in less than 5 this way. Both flashed with ease and the stock rom is much faster than AOKP. although I do miss the options and root I can live without it.

I am thinking something was not right with the flashing of the AOKP. I have re-done it about 6 times trying different things and it always ended up the same. Shortly after booting it turns into a sluggish turd. Updating apps made the tablet unusable. It would work fine at first boot and maybe one after but every use after that it got slower. Wiping the cache and dalvik fixed it but you started with a clean slate to set up all over again.

I wish either CM or AOKP would have worked better but they did not. I may try again over this rom but after a few days of playing with the stock rom.
[General Questions and Answers] CXZa:
Which firmware this you now have is exactly? Link?
[General Questions and Answers] dr_bowtie:
I did a google search for Hannspree Hannspad 10.1 and forund this .eu link

https://www.hannspree.eu/en/faq-tablet/hannspad-10-1-sn1at71

The first FAQ I hit the second line and got the .pdf and there is a link in it for the latest firmware.

Android version 4.2.2

Kernel version 3.4.0 Tue January 7 16:58:21 CST 2014

Build Number 20140515E-V1.3.0_HJT-FW8963-10.1-0x27-0x06

That was different looking than what I already had which was the latest the OTA said and I cant remember what version it was.

I left friday and turned the tablet off and came back today and turned it on and it still had 99% battery. So the drain issue is now fully gone and it holds a charge while off...

I am not sure how easy it would be but if a port to CM 10.1 from this rom could be made it should be pretty good. I thought about trying it as there are many ways it can be done according to Google and youtube.
[General Questions and Answers] CXZa:
For that there should be one minor(?) ota update available. (140515to141016)

CM, looks easy-peasy (not really.)

https://wiki.cyanogenmod.org/w/Doc:_porting_intro

As you might have noticed Troy's old source is available so it's possible to use it as a guidance.

Also the latest Actions' source 20141224 for 702a tablets can be found. So it's possible...

The kernel source isn't open though. 702c kernel's source is, but can it be used?

I tried once converting a newer boot into CM boot but it didn't start. Should try doing it

manually if there is some more differences other than the kernel and the modules.

That auto-rotating recovery is odd as init doesn't load the module. Is it baked into kernel? IDK.

What if you use portable over it. Does it still rotate?
[General Questions and Answers] dr_bowtie:
TWRP portable and permentized Auto Rotated. CWM did not. I have not tested it since flashing the stock recovery or rom.

This version rom works very well. zero battery loss when sleeping long period of time. Tablet has been ON over 24 hours but sleeping and has had zero battery loss. Prior roms it would have been dead after 8-10 hours.
[General Questions and Answers] CXZa:
After some manual work I did today I found out that it's galcore.ko module that causes the issue. At least in my tablet.

One can change pretty much all misc/boot files (including ramdisk) except that one. It can be some minor value somewhere or maybe one have to change some system files to make it work. I don't know - yet....

So newer kernel etc, can be used with those older Troy ROMs, but does it help anything. IDK.

My Ainol Crystal 2 has worked quite well so far. Only browsing starts to get slower and

then much slower over the time. Restoring a backup fixes it. (as well as some other tricks).

So, other that browsing my 7029 tab has served me relatively well....

What is the best update today for a tablet having Actions' 7029 SOC?

- A new tablet.
[General Questions and Answers] dr_bowtie:
Agreed.

As previously stated I only bought the tablet, like others have, because it was cheap and supposed to be decent. Something cheap for the job I was doing at the time. I didnt want to use my good tablet and risk getting it broke or worse, stolen.

Beings I havent worked at that job in over 2 years I've not needed the tablet and just tossed it in the cabinet. I would get it out time to time and just check the charge or charge it every couple months. I only get it out when I'm slow and just need something to tinker with.

I had always hoped there would be a custom rom that would "magically" fix the tablet much like it has other tablets. The only way I can see to fix the sluggishness after a few uses is to do what Lenovo did for the A2107 and clear the Cache on every boot but then you get the irritating Optimizing Android on every boot but that pretty much fixed the issue on that sluggish turd.

After not touching the tablet for a long period I was surprised to finally find custom roms for this tablet and hoped that would help but for me they did not. They wouldn't have been bad but for the battery drain issues. I was optimistic that they would fix some performance issues but I am surprised how well this stock rom works from a very clean flash.

So far the tablet has been on since Sunday and it is now friday and other than me playing some games from the SNES9x app it still has 80% battery. It looses no battery while sleeping. Before it would have been long dead after 8-12 hours. This thing really goes into a deep sleep on the stock rom and has stellar battery life right out of the gate.
[General Questions and Answers] steve30x:
I'm curious but is there an app I could use to reside the navigation bar and keyboard. The navigation bar and keyboard are absolutely huge on this new tablet. The navigation bar at the bottom is especially way too big.
[General Questions and Answers] wyelkins:
Just a side note. I have had this tablet for 2 years and never liked it except for the big screen. I recently moved and got a roommate and fast Xfinity Wi-Fi.

Gave the Hannspree to my roommate and she loves it. She uses Facebook and plays games. Lol. Not computer savvy but it works great for her.
[General Questions and Answers] steve30x:
I'm the same. The T71 is terrible. I hated the thing and the so called IPS screen had horrible colour reproduction. I gave the tablet to my sister and she loves it too. This Hannspree Titan 13.3" tablet is a whole lot better though. I compared it to my Samsung Galaxy tab 4 last night and this tablet is slightly faster. If you are looking for a good big screen tablet I highly recommend the Hannspad Titan T72 2015 model once you don't mind being stuck with android 4.4.4.
[General Questions and Answers] dr_bowtie:
you cant even get that tablet currently. At least not in the USA.
[General Questions and Answers] steve30x:
Holy crap when I was buying this there was no problem in finding it. Almost every place had loads of stock> I was cautious when I bought the Titan because of my bad experience with the T71 but it turned out to be a gem for the price. They say nobody likes tablets anymore well maybe people want bigger tablets by the looks of it because the 13.3" titan can't be found anywhere. Its well worth the money.
[General Questions and Answers] dr_bowtie:
Or maybe a smaller run number? After you posted I thought about trying to nab one.... no such luck.
[General Questions and Answers] CXZa:
Is there such roms out there really? Maybe - after several versions...

The thing with these custom roms was that people didn't make enough

donations to Mr. Troy and therefore he dropped the development in very

early stage.

Last time I tested his CM 10.2 to see if TRIM was supported. It was last summer.

I probably used some newer firmware as the base and maybe that's why there was

some issues like battery draining. Anyway I didn't continue using it. And the TRIM

didn't work either. Now using the last kernel and modules etc. there diffidently

is a battery issues so I'm back using the 4.11 stock. I remember using Troy's PA 4.3

one summer when it was a newer thing and I liked it, but I changed it to 4.11

because I needed ad-hoc working at that time.

[General Questions and Answers] dr_bowtie:
Oh speaking of stock.... I checked for OTA updates on the T71 and it says cannot connect to server or something like that so it cant check for updates. But this one from the official site works very well for stock. as long as you dont use WiFi the battery last an amazingly long time... 7 days now still at 80% sleeping. I've checked it every couple of days.
[General Questions and Answers] dr_bowtie:
14 days later and it was still at 80% so I decided to play a few games on it with SNES9X and add a bluetooth gamepad.... seems the only thing that kills this tablet faster than WiFi is Bluetooth..... bout 30 minutes and the tablet just shut off. It was dead.
[General Questions and Answers] steve30x:
I have PurePerformance flashed to my Titan and it turns off WIFI when the tablet sleeps. When I got the tablet new I was getting four hours of video playback and just barely eighteen hours idle battery life from the tablet. Now I can play 1080P movies for eight hours and I get three days from the tablet if I use the tablet occasionally. When I use bluetooth though the WIFI gets FLAKY with the tablet.
[General Questions and Answers] dr_bowtie:
I was very surprised to get 14 days idle/sleep time out of this rom on the tablet and still have above 50% battery. honestly I dont find the tablet to be much use if it cant live on WiFi or bluetooth very long. Tablets arent much good if you cant surf the web without killing the battery quickly.
[General Questions and Answers] steve30x:
Turning on WIFI is the biggest problem with tablets second to that is facebook. The WIFI drains the battery a lot in all tablets I own. I just wish they could fix this problem.

[General Questions and Answers] steve30x:
My 4 gen 10.1" and 7" galaxy tab , Acer A500 ,Hannspree TITAN 13.3" 2015 tablet and Sony E1 phone has the problem. My phone lasts up to a week with WiFi turned off. My Acer A500 four year old tablet lasts two days with WiFi turned off. The galaxy Tab 4 tablets lasts four to five days with WIFI turned off and this Titan tablet lasts just over three days with WIFI turned off. So its not just this Hannspree HSG1279 that has the problem. Most mobile devices has the same problem.
[General Questions and Answers] CXZa:
Here is a xmas "hack" if you want that the TWRP uses the same properties as the stock.

Before "permanentizing" just delete the file "/res/twrpdefault.prop".

Then it should work when flashing stock packages if the reason is

the checks in the edify script (sometimes it's e.g. the update bin used).
[General Questions and Answers] dr_bowtie:
every phone I had has the issue as well...

I can get up to 4 days on my one-plus from a full charge with wifi on but sometimes in airplane mode it seems like it uses more battery. My S3 only last a day with wifi on. That has drain fast.
[General Questions and Answers] CXZa:
It's not an issue, it's a feature... The way draining now happened in CM was that

it stayed like 80% very well even if screen was just closed, but it went down

quite fast if I used it after that. I assume it just took time to show the real percentage

(although I didn't made any comparison to see if there was any difference between

using after-screen-closed (over night) and right after recharging).

Hi,

I have ressurected the T71 to give it to my daughter (rooted, CWM last stock ROM), and not a surprise, the stock ROM sucks.

Reading through this thread, it looks like AOKP 4.2 ROM is the most suitable for this tablet. There is a download link for it (CWM backup file) in post #915, but it is dead. Does someone still have it and can reuploat the ROM CWM backup?

[General Questions and Answers] steve30x:
If there is one bit of advice I would give anybody is don't buy Hannspree tablets. I have a Hannspree Titan tablet from 2015 and they refuse to upgrade its os to KitKat. Theres nobody working on an OS for it and I've broken the damn thing a few times just reinstalling the OS that came with it because after a few months the thing slows to a crawl and the only thing that makes it run at a semi decent pace again is a clean install. Then to reflash the tablet after it soft bricks I need to install windows 7 which is a complete pain to do with this new motherboard and CPU I got three months ago. Theres no windows 10 drivers for the tablet. I even tried running the windows 7 driver in compatibility mode but that doesn't work. So it would be a pain to try and create a new OS on the tablet when I use it every day. I would need a second tablet to work on.

They also brought a Titan 2 last year (2016) with Lolipop on it and they are not upgrading it to Marshmallow which is a 2016 OS. They make tablets with an old OS and never upgrade them. When I can I am buying a Yoga Tab 13.3" tablet which is far better (I know its only marshmallow but it is a much better tablet)
[General Questions and Answers] tamelion:
Is there please anyone who can post a dump of the recovery partition of the T74 model? I have screwed my recovery (white screen) and don't have a backup :(

Something like this should do the trick:

cat /dev/block/acta > /sdcard/recovery.img

Would really appreciate it if anyone can help!
[General Questions and Answers] CXZa:
The firmware for T74 can be found from my blog. (And for T71 too.)

http://cxzstuff.blogspot.com/2016/11/some-of-firmware-and-tool-packages-i.html

You can split the firmware using the Pad Modify Tool (see my signature).

Find the img under C:\ProgramData\PadModify or use its command line tool

like this: ExtractFWData.exe "thebigfirmwarefwfile.fw" "outdir"

edit: or you also just copy files from the misc partition if recovery.img or its bak is ok.

Copy everything except the boot and modules.
[General Questions and Answers] tamelion:
Wow, thanks CXZa! I had indeed totally lost the recovery.img and bak. I had previously found that firmware and was put off by the naming of the file ("jellybean" etc.), but since you seem to be well respected around here I gave it a go -- recovery.img now back where it belongs! :D

My outstanding (and actually original) issue now is that when I rooted it seems to have broken bluetooth. Would love to be able to flash the whole firmware without using that pad tool (I have been running it in a VM and it's crazy slow, I'm quite worried about using it to flash).

edit: Just tried - my VM can't handle the USB device directly anyway, so it is definitely not possible for me to use the pad tool

I was thinking I could do something similar to this, with the system.img and OTA.zip I've extracted from the .fw -- but I don't think this tab lets me load to bootloader for fastboot?

fastboot flash system system.img
fastboot flash misc misc.img
adb sideload OTA.zip

Any other suggestions would be greatly appreciated!

P.S. -- not sure what the PAD.fw is -- would I need that too?
[General Questions and Answers] CXZa:
With what you rooted that? My package uses the edify script which has code from the ota.zip.

Done lazy way - I admit - but it should not mess the rights and such.

>Would love to be able to flash the whole firmware without using that pad tool

Are you using linux? There is also a version for linux.

>I was thinking I could do something similar to this, with the system.img and OTA.zip I've extracted from the .fw --

The edify script inside is for traditional update.zip. But the update-binary (and recovery) tend to develop in these.

Basically you could try flash it in recovery and it might write the img files put to /mnt/sdcard/burn/ folder.

Check update-binary with a hex editor for more info, also stock recovery gives some clues what's might work.

I have done some experimental packages for Actions' SOCs having kitkat firmwares but that was before I ported

KK to 7029. And I haven't really tested them in kitkat myself yet. Like my Images2partitions tool which is made

for 7029 might work in this case too. But it needs keys file changer flashed before. It needs some testing.

You can also just cat the system and misc to their partitions by hand. Just simg2img that system file first.

> I don't think this tab lets me load to bootloader for fastboot?

Your thinking is correct, AFAIK.

>not sure what the PAD.fw is -- would I need that too?

Nope if you are just pushing img files to partitions.
[General Questions and Answers] tamelion:
>With what you rooted that?

Totally nothing you've done at all. Unfortunately I used KingoRoot when I was feeling particularly lazy -- no idea what it did to my system, which is why I'm keen to start fresh!

> Are you using linux? There is also a version for linux.

Yes -- however it uses python script (for python2 as far as I can tell) and it just segfaults before it can even do anything. No idea how to debug.

> Basically you could try flash it in recovery and it might write the img files put to /mnt/sdcard/burn/ folder. Check update-binary with a hex editor for more info, also stock recovery gives some clues what's might work.

The burn folder is referenced, but not for those images. I tried it anyway, but it flags the OTA.zip as not being signed, so it wouldn't use it -- any way around that?

> You can also just cat the system and misc to their partitions by hand. Just simg2img that system file first.

Are you sure about that? Via ADB on a running system, I can just wipe the system partition??

I've also made a diff of the system and misc partitions in case I can copy/remove files manually, but I have the same reservations about doing this on a running system (and it'll be quite a convoluted task).

EDIT: I managed to use ADB in recovery (pretty sure I couldn't do this before, perhaps it's enabled in the new recovery?!) and used busybox to cat the (raw) system and misc partitions over! :D SOOOO happy right now! Thanks for all your support CXZa. Would love to understand -- is there a reason why people don't/wouldn't use this technique? And are we "lucky" here that the system partition is ext4 instead of yaffs?
