[Q] Gv-21/Kimdecent T21/intcrown T9/ZW608/T301 Firmware Rollback/Downgrade - Android Q&A, Help & Troubleshooting

Hi, I'm hoping that somebody could help me here as i am in a real pickle.
I bought a Kimdecent T21, Which i believe is the same as the Intcrown T9, the GV-21, the ZW608 and theT301, with the last two looking unlike the others.
Anyway, I had one before Christmas, and loved it. I could use BiggiFi VMG on my phone and control it, the WiFi was excellent as was XBMC. My sister came home from abroad for Christmas and she loved it, needless to say, i no longer have it.
So i bought a new one. But the new one arrived with the latest firmware, and a version of XBMCAndroid installed on it, but it doesn't work. It just loads into a black screen with the cursor. The WiFi is atrocious and sometimes other apps just load as a black screen (I think that's when XBMC is 'running' in the Background).
I have looked everywhere for the old firmware but i can't find it. I found a version of it on the Kimdecent website, but every time i try to 'Make' the Firmware card, i get an error saying - CopyFile "bootfs" error error code=1005 firmware. So i think that version is corrupt.
I also found a version on the intcrown website, that one worked, but it is the same firmware i have on the stick already.
The old version had two XBMC apps, i can't remember what they did, i think one was a server or something, and the other a remote? I'm not sure. I had to install XBMCAndroid myself. So this one is different.
I have uninstalled it, installed versions i know work on it, and i have factory resetted it, and installed XBMC on top of the existing version, still nothing helped.
Does anyone know what i can do to fix this, or maybe somebody can help me find an old firmware. I've looked everywhere i can think of, and more, and i found nothing. I am about to fly an email off to Kimdecent again, but they don't seem to reply to them.
I'm really sorry for the long post. Hope someone can help, and thanks for reading.

I've killed it

In the words of Homer DOH!!!!!!!!!!! I have killed me new MDA III
Last night I was trying to get the sync software to work and it didn’t so I have a look round the net for some upgrades, found one which sorted 50% of the problems so carried on looking.
Well I ended up downloading something which I though was a upgrade to the windows software but not (trouble is I now can’t find the site I got it from), I have killed it BIG time, Windows has gone and the only thing that come up on the screen is “Serial 2.05” had a look on the windows CD that came with it and it’s just a help file the O/S is not on there.
Now this is my first PDA and in 2 days I have managed to kill it, how do I get the O/S back on?
Your device is in the bootloader mod.
Download one of the ROM packages here and execute. This will load the ROM into the MDA.
hi
i killed mine as well but what you need to do is find the same rom that was on it and try upgrading it i did a few till it finally worked also there is a previous tread on hit. http://forum.xda-developers.com/viewtopic.php?t=12101&highlight=

Camera not working :(

Hey Guys,
So I just received my prime and I updated it to ICS. I opened up the camera app to play with it and both cameras work. But about 20 minutes later I open up the camera app and I see a bunch of green lines in the "viewfinder". It then forceclosed.... I now am unable to open the camera app. I have tried to video chat and only the frontfacing camera works. I have also tried to use "Retro Camera" and it does not work either. I did a factory reset and nothing changed...

Any ideas?

rear camera not working after firmware update???
I'm having the same issue. I received my 32gb Gold prime from amazon yesterday and immediately update to ICS and camera update and now experiencing the same issue as your. I did not test the camera before the update and so i'm not sure if the update cause it or if the camera was bad right out of the box. I did factory reset twice but the problem still remains
Looks like you guys both need to send them back in for replacement.
That sucks. The sooner we get bootloader unlocked the better.

ASUS response: Um...yeah...some update screw up the camera...we are sorry, we know the problem. We are going to update our spec to say that the cameras does not exist. Please ignore the 2 lens sticking out from your tablet. Thank you for buying our product.
Same problem
Anyone found a fix? I have the exact same issue. I will try to restore it to factory default settings tonight and let you know if it helps.
Just to test, has anyone with this issue tried to clear the data from the camera app... settings > apps > camera
OR, try and download a different camera app and test and see and if it works. I use Camera Zoom personally and not the stock camera.
Guys......there is a firmware update specifically for the camera. Go into settings and check for updates. If nothing shows up you will have to wait until Asus posts direct links on the site. I'm surprised I'm the only one that knows us.
Your not the only one who knows this. I have received 2, maybe 3 in total.
But, I assumed they already got their updates as the moment you turn on your device, these are shown to you so you cannot miss them when they come around. If they went to ICS, they should have gotten a notice for the camera at the same time. There was another under HC as well.

Good point. Now the question is if you guys have gotten the camera update as well?
Update
I just did a factory reset and it doesn't work. Its weird that I cannot find many cases of this happening from forums online, so here are a few details that might help clarify things:
First, yes I have upgraded to the latest firmware and tried clearing the data for the camera and anything that could even remotely be related (media processes etc). And yes I have tried using other apps that use the camera, and it still doesnt work.
Second, the camera worked before. It worked prior to and after the ICS upgrade, and prior to/after the firmware upgrade for the camera. It just stopped one day for no reason.
Lastly, its only the rear facing camera. Most of the time it is just a blank black screen, but every once in a while it comes up with a green screen with what looks like the ghost of some of my desktop icons. Ill post a screen shot.
I would really rather not have to send in my TFP but im starting to come to the realization I may have to. Its frustrating because I know it worked after the most recent update, so it must be a software issue and not an issue with the camera itself. 2 weeks is a long time to live without my baby...
Any help would be greatly appreciated.
Android version: 4.0.3
Camera Version:TF201-0x9900
If you cleared data, reset, tried other cams, updated firmware, what more can one do? Sorry man it sounds like some sort of defect.
firmware
Does doing a factory reset re-install my camera firmware? Is there anyway I can reset to prior to the ICS or camera firmware update and reinstall it?
No, once firmware is onboard it is onboard, it is not undone via a reset.
One last update
One last update on my problems. Got off the phone with ASUS a while ago and they had me do a full data wipe. Volume down/power and everything. Didn't fix the issue. Gave me an RMA and a sad heart for two weeks.
Looks like Ive joined the ranks of those who had a problem with my TFP. Shucks, things were going so well...
Best buy
I have spoken with Best Buy, and they are willing to send me a new one when they are in stock.... I didn't want to mess with Asus and this way, I won't need to send mine in.

Maybe if we both return ours to bestbuy at the same time they will just swap them . I have a skinomi on mine, Im going to call ASUS and see if I can avoid removing my bubble free masterpiece.
Hey guys did anyone find a fix for this ? I just got this problem.. or do i really have to contract asus..
Same prob. Here and I just try to correct it with rom manager and reset permisions. A downgrade to honeycomb doesen't helped 'cause the camera firmware dosen't go down, so there is no way to correct it, so i wolud say that the driver's a broken...
Not sure how I missed this thread before.
The exact same thing happened to me. Called ASUS, they had be send it to them (at my expense, of course). Sent it in late January, sat in TX "waiting for repair/testing" according to the RMA status site. After a month of nothing being done I sent an upset but not irate email, and they "fixed" it and sent it out the next day. Got my tablet back a few days later (roughly March 1st), everything was working fine. Now, not even three weeks later, the problem is happening again. I called, they want to fix it again. At least they're paying for shipping this time, supposedly.

[Q] Stuck at boot "Password Failure"? Please advices

Hi everyone, I've been lurking around here unregistered since I got my first Android device last year, namely the ZTE Blade.
Now however, I'd love to get help because somehow I've managed to make my brand-new tablet not to boot, and I seek expertise from the experts.
I've searched around both Google and here on XDA, but haven't found anything because I don't know how to search for it, due to the fact that the error is in Chinese.
So to make a story short I just arrived today from a trip in HongKong.
I was very pleased with my ZTE Blade so I decided I'd buy a cheap Android-running tablet during my stay, and so I did.
I got myself an "Acho C908", which I tested in the store first. May be an unknown brand, but it's a really nice tablet.
It sure has nice specifications and I was pleased with the performance for the price I payed, however I managed to make things worse.
Everything was going good except I couldn't install any apps in Playstore, I always got the “Error Processing Purchase DF-BPA-09″. So I searched this error up and found the guide: ...technipages.com/google-play-error-processing-purchase.html
I followed the guide and cleared the data from Google Services Framework. However, after doing so things got bad. My tablet began to freeze so I restarted it. After it booted the "explorer" (forgot the name in Android, refering to Windows-term) didn't answer and crashed and the tablet froze again.
So I rebooted it again and here's where I got stuck.
The thing is that I don't seem to have bricked my tablet, because I'm able to pass the boot logo, however I'm getting stuck at something else. The worse thing is that because of the tablet being a Chinese one, the text is in Chinese! However, this happened to me at the airport when I was heading back from HongKong so I managed to ask some Chinese people.
Here's the "error".
XXX.img692.imageshack.us/img692/4594/tableth.jpg
(please replace the XXX with WWW)
From what the Chinese people I asked told me, it says something about "Password Failure" and that I would need to "Reset to Default Settings"?
I have tried to enter some sort of Factory Settings/Hard Reset mode, but holding Volume+ or Volume- or both together during turn on of the device yielded nothing but getting stuck at the first logo during start-up, namely "ACHO".
So do you have any guesses on what to do?
I actually bought two of these tablets, one for me and one for my father. So if there's any information on the working tablet you would need to help me, I would be able to provide you with that.
I'd love to get my new tablet working.
Thank you very much in advance.
Best Regards

Nokia Lumia 920 Screen Shimmering/Flickering

I cant find a straight answer anywhere. I bought a Nokia Lumia 920 a week and a half ago and I'm on my third handset. This is because each one has been apparently faulty.
The first handset I had was great until the screen started to flicker/shimmer to the point where it hurt to look at it. I got that one replaced with a second device, which was better, up to the point the flickering returned and it froze, shut off and wouldn't turn again. I got this one replaced with a third device and this one was flickering/shimmering straight out of the box.
I have looked on google followed tips and tricks to try and get this phone working but to no avail. So I just wondered if you guys knew of anything im missing or a ROM I can install to fix these problems or future updates which will fix these problems because I am going into the EE store tonight to get my money back. I am so annoyed because its a beautiful phone and I would like to keep it.
Thanks
Sam

Sounds to me you have something in your area causing it. Maybe a very strong electrical/magnetic field. Just seems odd three in a row would have the same issue and so far I am pretty sure you are the only one to report this since you found no answers as well.
Keep in mind that per FCC rules your phone must accept interference but may not cause interference. So if there is something in your area causing it then you are out of luck as it is not an issue with the phone.
Unless its the entire area of bristol or im just magically electro magnetically charged i dont think its that. I'm not the only one who is getting this problem, I said I cant find a definitive answer. I cant find an answer about updates or patches that would fix this problem. I understand that phones and radiowaves are very susceptible to interferance but this problem is happening in different places and at different times.
I've managed to find that the shimmering will happen more while multi tasking so having headphones plugged in, music and trying to access the xbox app.

Lots of issues with LG V600TM

Hi guys.
I'm quite new here so forgive me if I put the post in the wrong place.
Let me try to describe my issues with my phone.
A couple months ago I got a new LG V60 from my wife (brand new but without warranty).
The first problem I noticed after a few days was that the fingerprint scanner wasn't working properly. I mean everyone can unlock my phone after a few tries placing finger on the scanner at an angle.
When I try to unlock the phone by fingerprint it takes ages (it's very difficult to unlock the phone for the first time). I was trying remove saved fingerprint and create a new one but the problems is still there.
Another problem is with losing signal from satellites when using navigation. I was trying Google maps, Sygic and TomTom and it's look like the Google works best but there is still problem with signal, quite often I get information about 'searching position'.
Next one is that the phone is freeze sometimes and I have to restart it to work properly. It's happening around once a week.
I was trying hard reset but it didn't fix it, then I downloaded the original firmware with android 10. I don't know if it helped because I got lots of updates and it ended up on the Android 12 again. At the beginning of use after this operation the phone was working better but after a couple of weeks the same problems came back.
I'd like to add if I want to do a back up I get information like this "the required google certificate has been deleted". On Android 10 this information wasn't appearing.
Do you have guys any idea what's wrong with this phone?
Thank you in advance.

I also have the v600TM on Android 10. I have had no problems with the fingerprint except after the first time I unlocked the bootloader (see 1st post for the fix). I did not allow an update to Android 11 or 12. Maybe you should try the fingerprint on A10 for awhile before moving to 12.
Hopefully you don't have one of those Chinese refurbs pretending to be new!

Hi
Thank you for the reply.
Maybe you right and I should try to use the phone on android 10 and see if it's works properly. I'll see what happens.
Do you know when android 13 will be available for V60?
As a owner of the V30, V40 I'm really disappointed of the V60 now.

Hi,
You're welcome. When you are new to a forum or group, its like you are invisible.
My current main phone is the V30. The V60 has been more difficult than past phones to configure the way I want. When I installed TWRP a few months ago it was a DISASTER! Installing MicroG (to replace google play services) has also not worked out well. I have limited funds and I am beginning to wonder if the V60 was a good choice.
There is already an Android 13 beta for some versions of the V60.
The thing with V60 is that it is newer than V30. So a lot of fixes are not fully cooked. With LG gone from the scene, there is no incentive for developers to pursue it with any dedication. I don't know if TWRP will be fully built for this phone.

I do remember how slow the V30 was in the beginning. Now the V30 has a bunch of ROMs and an OFFICIAL LineageOS! I hope the V60 goes the same way. I doubt it, though.

Hi guys
It's me again with another problem
As for the above problems that I wrote about, I decided not to do anything about it for now and patiently wait for the android 13 update and see what happens.
How happy I was when two days ago I received the opportunity to download the update.
The joy did not last long, as it turned out that I'm unable to download the update.
Previously, I got information like 'The phone is being use and update will be downloaded later' (or something similar). Now the update downloads for a while and pops up 'Installation problem' and cannot be downloaded (always in the same time). I restarted the phone, deleted apps, changed from WiFi to mobile data and still the same.
Do you have guys any ideas what can I do with it?
As far as I know the phone is from US (T-mobile) and I live in the UK.
Thank you in advance for your help

How to check if the bootloader is unlocked?
As I said before I haven't done anything yet with the phone as I was waiting for the update but I'd like to check it, maybe the bootloader was already unlocked

When the phone is starting up (after being off or rebooting) it will say something like: This phone cannot be checked for corruption. Lock the bootloader.
If the bootloader is locked I suggest you backup before doing a factory reset.
