[Upgrading, Modifying and Unlocking] dolorespark:
We've got a bunch of interlocking issues with this ROM, and I'd like to get them sorted out so we can conclude this ..umm.. project.

The biggest problem is that I don't know what fixed your WiFi: my changes to your bootloader or the new kernel and drivers I used to get the capacitive buttons working. There are two ways I can go to resolve the crashes we're seeing with the current package but I have to know which piece contains the fix. To get there, we have to mess with the Volume buttons first.

In /system/usr/keylayout you'll find sun4i_keyboard.kl (once again, I'm doing this from memory, so some names or details may be slightly off). When you open it, you'll see it has key values and the function assigned to each. Change the values for Volume Up and Down from 115 and 114 to 158 and 217. Save your changes, then reboot and retest the Volume buttons. Regardless of whether this fixes the problem, continue to the next step.

Go here[edit: file deleted] and download script.bin-158. Push it to nanda as usual, then reboot and retest.

Now, for the BIG test. I have to ask you to reinstall my original update.zip for this tab: trio7-a10-jb-dopa.zip. It will erase /cache and dalvik-cache but not /data so all your apps and settings should still be in place. After it boots up, does WiFi still work and/or do you get this line in dmesg: ehci_irq: port change detect.

Two caveats for this test:

1) be sure to install script.bin-158 before proceeding. Beside changing the Volume buttons, it also includes additional parameters for this version of the touchscreen driver - without these in place, your touchscreen won't work

2) do

not

flash any of the LiveSuit images - they'll wipe out the stuff this test depends on.

With the results of these tests, we should be able to come up with something that works without crashing.
[Upgrading, Modifying and Unlocking] kevmodee:
After edit of sun4i-keyboard.kl - no change

after script.bin-158 i have vol+ as a back button and vol- launches google search and that reboots the tablet.

I decided not to do update from original trio7-a10-jb-dopa.zip as I am thinking maybe with these results on the first 2 tests the "BIG" test may not turn out too well.

It's late - I will revert to previous script.bin-mma7660 and wait for your comments.

If you think doing all 3 steps is still a valid test I will repeat and go with the trio7-a10-jb-dopa.zip tomorrow.
[Upgrading, Modifying and Unlocking] dolorespark:
After you change the kernel by reinstalling the original update.zip, the crashes will be gone. The question is, will the wifi be gone too? Getting other stuff working correctly is secondary and can be fixed later. One exception is the touchscreen - it's hard to test your wifi if the screen doesn't work. The real purpose of installing script.bin-158 was to ensure it worked after your reinstalled trio7-a10-jb-dopa.zip.

Based on your results, I'd ask you to install script.bin-115[edit: file deleted] instead, then trio7-a10-jb-dopa.zip[edit: file deleted]. After doing so, you'll have a kernel that doesn't crash, a touchscreen that works, and maybe keys that work correctly.

The great unknown is whether the wifi will work. If it does, we're almost done (we may still have to fix the gsensor). If it doesn't, I have a "Plan B" that shouldn't be too painful to implement, given all the info we've gathered so far.
[Upgrading, Modifying and Unlocking] kevmodee:
I should be able to try it tonight.
[Upgrading, Modifying and Unlocking] malmostoso:
This can be done quite easily by

# adb shell "svc wifi enable"

and then by checking the resulting dmesg.

I'll do my best to test stuff tonight, I am crazy busy at the moment, sorry!
[Upgrading, Modifying and Unlocking] dolorespark:
Now I know! Thanks for that.
[Upgrading, Modifying and Unlocking] malmostoso:
Alright, I had the time to try out your 2 fixes (script-115 and JB image). I installed both, and the wifi was broken:

The volume buttons did not work either.

EDIT: I'll shut my face. Changing the script makes the volume buttons work, but the wifi does not work with the new update.zip. Right now I have script-115 and the zip of Feb 22nd (should start versioning them maybe) and I'm in a good place. Also no settings went lost in all these changes.

Kevmodee, can you confirm everything works?
[Upgrading, Modifying and Unlocking] kevmodee:
I just installed script.bin-115 and after 2 reboots the volume buttons work (after first boot they were working but ui slider didnt move as i pressed)

Still cannot use vol+ to boot into recovery

I'll try zip later if I can

EDIT : I used Feb 22nd zip - WIFI is still ON, UI seems sluggish but all apps stayed on and volume still works - you said crashes will be gone - I still reboot if i launch google search as before. My extsd was whiped also. Only has LOST.DR and I had the zips there that I installed from.

UI is quicker after reboot from crash.
[Upgrading, Modifying and Unlocking] dolorespark:
OK, so the kernel is (seemingly) the key to having the WiFi detected.

It seems odd that you haven't had any crashes. One of them destroyed my data partition, requiring a "factory reset".

Ummm... that's because you reinstalled the update.zip you already had installed. No big deal - installing the other one would only have broken wifi.

Now for the good news (I hope): one more update.zip and we should be all done. I'm going to pair the kernel and drivers that seem to give you wifi with another Android build that doesn't crash despite the bug in this kernel. Like the other update.zips, this new one should preserve all your apps and data.

There are two possibilities here - let's try the simpler fix first. With the tablet booted normally, press and hold the power button until it turns off. IGNORE the shutdown popup because using it will force the tablet to boot normally the next time you power on. Now try to get into CWM. If that doesn't work (after several tries), the problem is in script.bin.
[Upgrading, Modifying and Unlocking] malmostoso:
I think that's rather safe to say.

Never had crashes. It gets painfully slow sometimes if some sort of background activity is going on, but as long as I stay in one app it all works fine. I guess the fact that it has a single core CPU is the main cause for that.

I was wondering why it's /so/ bad though. The ARM architecture is actually worse than x86 at multitasking? Or is it Android that sucks donkey balls? Or maybe has it been so long since I had to deal with single core device? Anyway, that's all besides the point.
[Upgrading, Modifying and Unlocking] dolorespark:
Not necessarily... This kernel was taken from the Seby Speed 4.1.1 ROM mentioned earlier in this thread. Given that several people reported that ROM failed to restore WiFi, the fix appears to involve several components, only one of which is this kernel. The other components that may have contributed to the fix are: the two bootloader files taken from your GB ROM, and the script.bin you're using which contains a setting copied from your GB version that I've never seen in any other version.

Just to recap: the problem was never a driver issue. Rather, the kernel failed to recognize the wifi module attached to one of the USB ports. My guess is that it wasn't being properly powered up by other ROMS. Some combination of these 3 components (kernel/bootloader/script.bin) work around this hardware problem and enable the wifi module.

I should have a replacement update.zip ready within the next day. Assuming that everything still works (and it doesn't crash), we'll be done.
[Upgrading, Modifying and Unlocking] kevmodee:
Not sure why I did not get this response the other day but . . . . I flash speed seby411 image and then booted into recovery and mounted system.

Then pushed script.bin-115 as you instructed previously. Rebooted and on the lock screen I selected google search by accident and it crash/rebooted like your version has been for me.

It came up again so I thought I'd try wifi and IT STARTED!

I swear I tried these steps the other day on a wild thought this might work. Well anyway - tonight it did start wifi with script.bin-115.

I thought you might find this useful in focusing on what really is the key factor.

EDIT: Same reboot crashes as with yours - google search and voice search

NO gsensor - no option in display setting - shows as selected on the widget bar but on or off screen will not rotate any direction.

Cannot get into recovery from Vol+ and power.

in key test

vol - = 72

vol + = 73

power = 74

so vol - is navigating and vol+ is selecting and power works like BACK

vol - and + work correctly still

WIFI is staying on after multiple reboots
[Upgrading, Modifying and Unlocking] dolorespark:
Well, we've got a good news/bad news situation then. The good news is obviously the wifi. The bad news is that my fix for the crashes was simply to switch to that ROM's version of Android because it doesn't crash for me. I'm still going to package it up for you to try - I make

far

more changes to a stock ROM than anyone else does, so maybe you'll have the same good results I do. It should also fix your gsensor.

Even if you force the tablet off as I described - is that correct?

The values are now what they should be (which is why they do what they should when booted normally). The navigation issues in CWM occur (I think) because you're now using his package of it, not mine. I'll post mine which, oddly enough, you can install as an update.zip while booted into CWM. Beside the physical buttons working correctly (I hope), you'll be able to use the capacitive buttons as Back keys.
[Upgrading, Modifying and Unlocking] kevmodee:
I could always boot into recovery but on seby ROMs with novo tools I seem to remember not being able to before. I tried a few more tries with + & - and neither got me in.
[Upgrading, Modifying and Unlocking] malmostoso:
Just as a reference, you can reboot into recovery even if your touchscreen isn't working by using

# adb reboot recovery

Very handy.
[Upgrading, Modifying and Unlocking] Joshdmo:
Hey bros, i was ginving a shot to dopa jb rom, and no wifi, my trio never had this problem, i return to sebys0.7.1 ROM and i have WiFi back, dopa ROM loocks good, don't you get the fix for WiFi yet¿? Sorry for my english, thansks
[Upgrading, Modifying and Unlocking] dolorespark:
I've posted that ROM - it's Trio-A10-JB-mma7660.zip. I've had no problem with voice search but after using it enough, it eventually crashed and rebooted. The cause is associated with sound, and since each crash I got occured when tapping on something, I turned off "touch sounds" on my tab. I have no idea if this actually has any benefit but you may want to try it.

I also posted script.bin-115-v2. This one has the same recovery-key settings as your GB ROM, so maybe it will let you use Vol+ to get in (after forcing the tablet off).

If everything works (wifi, touch, gsensor), I'll post a final LiveSuite image and update.zip.

Note: this update.zip is based on the worst stock ROM I've ever encountered (I only have limited experience, so there are probably much worse). If you feel like it, try installing other ROMs, then pushing our customized script.bin. If the WiFi works, I'll be happy to construct a new update.zip based on that ROM.
[Upgrading, Modifying and Unlocking] kevmodee:
So first I flashed back to seby411 - I cannot get into recovery on it with Vol+ - I tried Google search and no crash.

Then I flashed to your livesuit CWM recovery with all the extra files - an I immediately push script.bin-115v2

Then updated from the new zip.

wifi is good

gsensor is good

touch is good

NOTE: - i did not back out the other files yet. (boot.axf drv_de.drv and sprite.axf)

It can still crash on Google search but in language&input if I turn off Google voice typing (after reboot that setting is back on) - then search will open - but still when I type there it crash/rebooted.

Another test is to use sound recorder. On seby411 i can record sound. On yours as soon as I press record it starts the microphone and crashes - that's why Google search and Skype also crash/reboot - i am sure it is the microphone starting.

Still no boot into recovery with vol+ but I really don't care because your nifty reboot button and now novo tools added - I use these anyway.
[Upgrading, Modifying and Unlocking] dolorespark:
The mic was causing a crash for me with my original Android but not Seby's - it seems like the crashes I get are the result of generating sound, not creating it. One difference between the two is that mine has all the latest updates to the GApps - I don't know if that matters.

It will never work while the GB files are still in place - guaranteed. Once you revert to the JB versions it may work.

I'm going to put together a new LiveSuite image with the latest script.bin & a copy of CWM with buttons that should work correctly. Then I'll release it and the current update.zip - along with a warning to avoid this package unless you have no other options. I sure wish it worked better...
[Upgrading, Modifying and Unlocking] Goes1967:
You can easily change the language of the original LY-F1 from settings to English and you will be fine.:cyclops:

Now, as WIFI didn't work on any of the ROMs you tried, I think that it is not the software that is causing the problem, it will be either the WIFI on the tablet itself (hardware issue), or your router settings, I suggest taking your table to a public WIFI and give it a try and see what happens.
[Upgrading, Modifying and Unlocking] Goes1967:
I posted a link to an original LY-F1 firmware here, look for it. It is in Chinese, but you can change the language to English from the language settings first option on the right. If you ever need to re-flash it, you have to do it suing livesuite.

Wifi Doesn't Return

Hey guys,

first of all, thanks for the people who are helping us "newbs" in getting our tablets set up, your posts have helped me very much in getting my tablet to CM9.

now to my issue, I have a Trio Stealth Pro 4.0 and it came rooted without Google Play, I sideloaded Google Play and subsequently installed CWM 5.5.

Afterwards, I installed CM9 and once it booted it up it was all good but I lacked Wifi and the soft keys. Using the LY F1 third party 1.2 zip got the soft keys to work but Wifi was still off.

At this point I read around the net and found a repository with LyF1 stock firm ware and proceeded to install the latest version (0.7.1) for board version (A710) and still lacked wifi. At this point I wondered if my wifi adapter had died in the transition from stock to CM9. I reverted to stock and Wifi still did not return.

At this point I managed to install the Gingerbread version of the LY F1 firmware and WIFI Is back! From here, I tried the firmware posted earlier based of ICS and WIFI has disappeared again.

Seems to be a driver issue.

What data can I provide to better resolve this problem. I just wanted CM0 working! Thanks in advance.
[Upgrading, Modifying and Unlocking] Goes1967:
I never had a problem with WIFI connection unless i put it on anything other than always enabled in its advance settings.

The problem with the WIFI connection as you said, is a driver issue, from what it seems based on your experience. If someone can crate a compatibility zip specifically for this tablet from its original firmware, this would solve all of the problems regarding this tablet.

Wifi lost

Hello and thanks for the help. I’m in the same situation that you with my Trio Stealth 7 pro. I have installed CM9 and once it booted it up it was all good but I lost the Wifi too so I reverted to stock recovery image that I had created and Wifi still did not return. I’m thinking as well that is driver issue. How can I help to solve this problem? Thanks.
[Upgrading, Modifying and Unlocking] Goes1967:
This is strange, because if you reverted back to the stock image, the WIFI issue should have been solved, this also happened with another user and it was only solved with the Gingerbread version. It looks like the gingerbread version of the drivers are much better than the ICS ones.

As for how to compile a compatibility zip file for this tablet, I don't know how to do that, maybe if we ask Christian Troy, the guy who is providing CM9 will be able to tell us how to do so.
[Upgrading, Modifying and Unlocking] travisc:
I'm in the exact same boat also! if someone could make a compatibility zip that'd be awesome!
[Upgrading, Modifying and Unlocking] jaylawery:
did your sound work when reverted to gingerbread?

[/COLOR]

Did you lose sound when you reverted to gingerbread? I did the exact same thing as you but when on gingerbread I had no sound. If I go back to ICS I have sound but no WiFi.

I have some logcats of the WiFi turning on when it works, and when it doesn't if anyone is interested in seeing them. I hope we can get this figured out soon, I'm going to be flying a lot over the next year lol.

Hallo

Have tryed diverent roms , everything that has to do with android 4 gives me no wifi , but sound .

2.3.4 gives me back wifi but NO Sound .

So oure Hardware is fine but the drivers are not right .

I have a backup of my stockrom but I cannot use it from 2.3.4 have to flash another 4.xx rom first to get cwm to run and read back my backup with the result nor Wifi

I am very close to put the tablet in the trash , specialy because I dont get any support from Machspeed , a downloadlink to the official 4.0.4 would be enough but nothing , that company is a piece of Sh.....

:eek:

Hope we get help here .

Thanks in advance to everybody who is willing to help .

Info

Hi. I have been trying some roms, with the gingerbread LY-F1 2.3.4 20120207 0.7.1, I have the same problem; I have wifi but not sound. Looking if in this tablet works the usb host, I installed the application USB HOST CONTROLLER and I found that the tablet has 8176:0bda realtek 802.11n Wlan adapter more specific I think: vendor: 10ec ("Realtek Semiconductor Co., Ltd."), device: 8176 ("RTL8188CE 802.11b/g/n WiFi Adapter"). I did this on gingerbread.

Might anyone confirm this on their tablet please? Just to check if it’s the same chip and try to look for help or a solution.

Something else does anyone has this firmware F1-2.3.4-20120312-0.9.1-a721574 installed just to know if happen the same with the audio I think is the last one 2.3.4 for the LY-F1 but I can’t downloaded in the official page is everything in Chinese.

Thanks to everybody I hope we could figure out something.
[Upgrading, Modifying and Unlocking] xtreme113:
Same on my tablet , usb host controller shows under 2.3.4 8176:0bda , Realtek 802.11n WLAN Adapter.

Another thing . installed the last build CM10 , its not working at all , without any compatibility file it is starting up to the locksceen , but no touchsreenfunktion

with compatibility 1.2 0r 1.1 or 1.2-cbw it starts to boot but then it hangs at the circle boot animation.
[Upgrading, Modifying and Unlocking] Goes1967:
This happened to me too when tried Christian's CM10, but with this one everything works, but it looks that the ROM overlooked the system partition all together, as I only had the internal 2GB storage adn the external SD card only seen by the tablet.http://xdaforums.com/showthread.php?t=1662324 see if this ROM will fix your WIFI guys.
