[Q]MTK6572 - Does not boot - Android Q&A, Help & Troubleshooting

Hello,
I have got a COSMO Mini S4 and it suddenly does not boot. The last time I did see it work, it was hanging on the boot screen (suddenly, I did not make it reboot). So I did pull the battery out. After that it did not turn on again. So I looked on the interweb, and found that I still should be able to flash it. It is recognized by the PC.
So does anyone know where to get the firmware files (a dump of someone else's would be fine by me). And some help flashing the phone.
Every firmware that would work is fine by me, I just want my phone to work again. I have some experience flashing cellphones, but never had a chinese one before, so no manuals availible allmost.
Thanks in advance!

[Q] Please tell me I didn't brick this...

So I know how annoying the "help me, I'm bricked" threads are but I really couldn't find the answer to my problem anywhere. I tried to flash the Euro firmware on a Chinese Ace. I've done this several times before on other phones and have never hit these types of bumps. It started with me trying to flash from froyo, I didn't see anywhere in the tutorial saying not to but because I couldn't find any firmwares that weren't just a onepackage I ended up just trying that. Well now I'm aware that was stupid because the flash never went through after a long time of waiting and now the phone hangs at a screen with a computer and a phone on it with a yellow ! sign. Pretty sure that's bad. I tried the tutorial on here about unbricking but its not working. I eventually found the right files to flash that weren't onepackage but now its too late because even those wont take. What can I do here? Anything? I really don't know what to do, its not my phone and I was just doing it as a favour for a friend because the phone was pretty useless with the Chinese firmware, but not this useless...
Does phone start in downloading mod?
And you write lots thing but not understand properly that you flashed one package or need one package firmware.
Onepackage firmware for galaxy ace you will find at samfirmware.com or sammobile.com
I can start in Download mode but its still not letting me flash anything with odin.
I never was able to get any firmware on it and now its not starting up.
remove ur battery, press the three button combination for download mode, and while u push those three button just insert the battery again. now it should magically go into download mode and u can flash other rom. u should ask someone to help u tho, its damn hard to do this alone
fixed!
Fixed it! So here's what I did for anyone who gets into a similar problem. First off, I never had a problem getting into downloading mode, so this wasn't a full blown brick I guess. I couldn't get Odin to finish the transfer, always hung at the beginning. So after going a little crazy I just kept doing it over and over, couldn't hurt, and then I started moving to one of the different USB ports. I have 7 and just kept trying them. Finally on the very last one it worked. Full transfer and this Chinese brick thinks I'm in the UK sippin on tea and crumpets! It sounds crazy but just moving around to different USB's did it!
Well, I can add up some more info about this case. I bought my Ace from China and i have never stumbled upon any problem flashing other firmwares.

[Q] Samsung Galaxy Tab 10.1 Verizon LTE (sch-i905) bricked, no recovery

Verizon Galaxy Tab 10.1 4G LTE (sch-i905)
So I got this tablet from a friend who said it was bricked, said I could have it if I got it working. So I plug it in and it turns on no problem, strange. wiped tablet and added a couple apps. Got busy at work and the tablet drain power. That's when I got to see it bricked, but still not sure why it booted for a bit for me.
Symptoms:
Boots to Samsung Galaxy Tab 10.1 splash screen (not the animated one after), sits there for ever.
Boots to Odin update mode
When booting to recovery I get a blank, back lit screen and nothing ever.
I've tried:
-Pushing clockwork mode to fix recovery
-I've had a hell of a time finding stock firmware for some reason (it isn't on sammobile), but I did find one eventually. I pushed it to the tablet via Odin, and it was successful, but rebooted to blank black back-lit screen. Have to hard boot and hold power buttun until I see the splash screen to get that far. I followed the guide on rootzwiki reposted on icsforums - www icsforums com/forum/showthread / 13525 (sorry new member can't post links)
-Followed another guide that involved draining battery completely, no go.
I don't care what firmware I end up on, or if I can use LTE (I won't anyway)
I'm a network engineer so I'm tech savy, but not heavy on Android OS. I'm looking for anything else I can try. I saw another method involving heimdall suite, but can't find the files for my model.
Any help or guidance is greatly appreciated.

I had this problem on my gt-p7510...
What I ended up doing was wiping my sdcard..I must have had something corrupt in my file system or a kernel issue( still not sure which )..
Since you have no recovery..I think you can use odin to repartition ( I CAN NOT STRESS ENOUGH THAT THIS IS JUST A GUESS )..I have not tried it..but i will search after this post to confirm..I also believe there is a way using ADB..again not sure..
I just wanted to post this so you would know somebody was looking and to maybe give you a couple ideas to follow up on...I'll search around and see what I find
Edit...I believe ADB will only work with usb debugging checked...But you can flash a stock rom in odin with re-partition checked..you need a .pit file....I think...
Edit...Here is a link to a stock rom thread for you're device..It seems to have helped a couple people with their soft-bricked devices..just follow directions in OP..no repartition checked. I cant even find a .pit file to do a re-partition with for you're device..
http://forum.xda-developers.com/showthread.php?t=1342995 Let me know if this works for you..
Thanks for the post!! Really appreciate it.
That firmware is the one I found in the end and tried. Odin pushes it ok, but then still doesn't boot. In fact after pushing that firmware it boots to backlit blank screen, but when hard reset boots to splash screen.
I tried a pit file I found that I thought was the right one, but it failed when I used that so it must have been wrong.

I have the exact same problem as you, except sometimes I can't my tablet to boot. I know it is a software problem because before I was messing with recovery yesterday, everything was working just fine. All I wanted to do was restore to factory settings and instead ended up bricking the device... If you find / know the answer, please do share.

Did you ever get this fixed? I've had the same problem for months. I just gave up and put it away. I recently fixed a Galaxy Tab 2 and now I want to see if anyone else was able to fix this i905 not booting issue.
did anyone know the solution of this question

No matter what, LG D620k keeps bricking

Hello all.
I´m pretty desperated at this point. No matter what, my phone (LG G2 mini D620k, I have 2 years with it) keeps bricking. Keep in mind I´m a noob in this world, so I´m looking for help here.
This started like 2 months ago, it bricked so I searched on Internet and did the hard reset. It worked well, for a while. I downloaded all my usual apps without rooting it, then suddenly: bricked.
Another hard reset, and again, it worked. So someday it started freezing, apps closing, so in like a week I used 10 times the LG Mobile support tool to fix errors. It fixed the phone but just for 1-2 days. So again, I did factory reset (this time from the phone, it wasn´t bricked), rooted it, debloated it, and worked fine for 48 hours. Last night it again, from nothing, bricked.
Did hard reset again. I'm asking here: what is wrong with the phone? What is causing this? Is an app? Too many apps? Hardware? Battery?
I love my phone but I´m tired of sitting 3 hours every 2 days fixing it. Cannot afford a new phone or looking for specialized help, so I´m asking here for help.
Keep in mind I´m a noob in this. Can someone help me?
Sorry if this matter is already answered, I did a search and found nothing like this.
Sorry for my bad english.
When you say "bricking" do you mean bootlooping (the LG boot animation keeps playing)?
If so, try to capture a logcat while it's bootlooping via adb. Let it capture for a minute, or so. Then send it to me.
Then, pull out the battery for a couple of seconds, put it back in and power up the phone. Does it still bootloop?

I have the same issue!! I've tryed every CM Rom, custom roms, stock roms and now latest RR, and still the same problem. After flash I install only FB, Messenger and Insta (it's girlfriend's phone) and after 1-2 days phone gets bootloop (only RR logo). I have to do hard reset and flash again whole system to work properly again (for a few days).
I gave my G2Mini to service (not LG Service) but they said that its motherboard issue (probably some boot memory is broken and has memory "leaks") But I think that it cant be this. If this is possible I would try to flash whole system on SD card not internal memmory, maybe this will work
help!

Grab a logcat via adb.
Install adb and Google's drivers (for custom ROMs, LG's for stock ROMs).
Let it record for a minute and give it to us.
I managed to install CM13, worked fine for a month I guess... started with random bugs "x app stopped working". So I restarted the phone and it's in eternal logo when I turn it on.
Since I'm a totally noob at this, I can't find a noob-friendly guide to make it work again.
:crying:

Wipe /data in recovery.
If that doesn't work, reinstall the ROM and 'pico' OpenGApps

Managed to connect it to my laptop (I could't before), used LGMobile support tool, back to original rom. I guess it will be matter of time to get same errors as before. At least it works again... idk for how long :s
Hard life for a android n00b :x
update:
it freezes suddenly (started in the middle of a skype videocall).
I'm starting to suspect it's a ram problem. Any ideas?
I have the same problem. Did you find any solution?

Need help with Samsung Galaxy tab 3 lite T110

I had rooted my T110, but it was still very slow. I took everything I didn't use out of there, including the default keyboard. I ended up getting a new tablet through a Verizon promotion, so decided to sell the T100. A friend was looking for one for her son, I told her to look at it and if he wanted it, to let me get it ready. I explained I had done a few things that needed to be undone before he could reset it. She either didn't listen or didn't understand. When he said he wanted it, she factory reset it. It started up and all seemed fine until she found there was no keyboard.
I have used Odin 3.09 and tried to put stock firmware on it. Odin says it was successful but it was still coming up without a keyboard. Now I can only boot into download mode. It only stays on for a couple seconds in any mode except download mode, and even then if it is not connected via usb to the computer it shuts down. I can't get it into recovery mode at all and as I said, to try to just start it, it gets to the first page saying Samsung Tab 3 Lite, then almost immediately shuts down.
Can anyone help me find an answer for this? I might be wrong, but keep thinking since I am able to get it to work with Odin, it is possible that I haven't totally lost it and still may be able to get a few bucks out of it.
Any help would be GREATLY appreciated!!!

Wogiz WX40 not working properly after flash with "stock" rom.

I only want my Wogiz WX40 to work properly again. It somehow got into a booting loop and I spent many hours figuring out how to flash it due to drivers acting unexpectedly, incorrect instructions for my device and so on.
I finally got it to flash with stock software I got from needrom using SP Flash Tool. However 1) none of the bottom keys work now and 2) it looks as if the resolution is set too high for the device and I think there is also some slowness when using the phone. I have tried clicking upgrade firmware and formatting the entire flash and using different versions of the software and the result is always the same - the bottom keys not working in particular makes it unusable. I tried downloading the stock rom from another location but after downloading it said I needed a password.
So what is the next thing I can try? I'm at my wit's end here and just want it to work again. Thanks for all help.
Anyone know what I should try? For example what custom RAM + firmware might I want to try? At this point I don't care what it is as long as it works. It's a MT6580 device if that helps.
God, I FINALLY got it working.
In case there's anyone else that runs into this: My mistake was getting the stockrom from needrom, every one of those roms for this phone is bad. Get the rom from shareas.us and use SP Flash Tool to flash it, and even then you have to try to get the one that isn't password protected with no password. Leave the battery in, turn the phone off, use option "format + download" in the software and click download BEFORE you connect the phone, NOW connect the phone and after a little while it will start downloading. Disconnect the phone when it's done and switch it on, it will take a REALLY long time to boot up the first time but it should then work.
That's what came from hours of trying to get it to work. The tutorials etc. online are so confusing, even some incorrect instructions like saying I should take out the battery that are completely false and I would never have gotten it to work if I paid more attention to them. I don't ever want to go through something like that again. I finally have my phone back.
