Hello, after playing with a tablet I got boot loop so below is solution for this.
This is what I wrote first:
I purchased Chinese tablet called CyberNav, there is link to the website with specs http://www.dracotek.com/cybernav-7-...ps-navigator-ultra-slim-wifi-8gb-gps70yw.html It works great and is worth the money. I received- on request- firmware for it, but it is with .img extension and I have no idea how to get to the files. Attached application PhoenixCard should install it on sd card but it does nothing. So there is my question- can anyone help me with it? Possibly root it? Or update to newer firmware version? I'll post a link to, just need to upload it to my dropbox on my next break at work.

im pretty sure you need a 3rd party application to flash that firmware, i think you load the .img file into the software on your pc, connect tablet in flash/recovery mode then flash it that way, dont know which software you would need to use though , sorry i cant help further
There is link to rar package http://db.tt/jm7eHfbq
If there is someone who wants to spend some time... Please help.

Some new infos:
As far I found out tablet is detectable during boot in adb, but it stays in boot loop. I think I've got right usb drivers.
I tried unyaffs the .img file using C:/unyaffs/unyaffs pw08.img but it shows file corrupted (might be wrong method?).
Logcat attached.
Maybe there is someone who will find what it's missing...
I see there is nobody who can help me, so... If some of u have similar problem with chinese tablet- bootloop, can't flash it with LiveSuit our update from sdcard, I found solution which worked for me. Using adb, pulled catalog /dev/data/ to hard disk, then deleted all dalvik cache, installed by me apps and almost every other file from /data on my hard disk. Then typed adb remount, then adb shell rm -r /dev/data/* to delete all data catalog on tablet. Then pushed /data catalog from my hard disk to tablet, and finally adb reboot. And it WORKS! Booting without problems. I wasted 4 days on research how to turn it in flash mode etc. But it was very simple.
Cheers

Hi, sek111
It was necessary to use the LiveSuite to flash through usb.
Thank you very much, from your post, I found the firmware for my tablet.
An experience with another low cost tablet with Bootloop
I happen to got my tab (Wammy from WickedLeak.org) stuck in BootLoop and was struggling to get a way out for the past 3 days, checking almost all of the posts for this issue!
The tab would stuck on the android loading animation despite running for 2-3 hours and after several hard reboots, it throw-ed following error-
Encryption Unsuccessful
encrytion was interupted and cant complete. as a result the data on your tablet is no longer accessible
to resume using your tablet, you must perform a factory reset. when you set up your tab after the reset, u'll hav an opportunity to restore any data that was backed up to ur google account
Click to expand...
Click to collapse
Despite going for the factory reset, it still didn't workout as the reset activity never completed or proceeded. I happen to be a beginner/noob and was trying my luck with possible solution but was comfortable with ADB stuff and workaround. Well i checked the solution which sek111 offered in this post and it was most closely helped me out. So i would like to Thank him a ton for sharing his solution.
Another method for few others if you don't get through the technical stuff and handling all the flashing tools, i was successful in bringing up the setting window of my tab and chose to do Reset via GUI which worked. Actually my battery got drained out to 7% and a popup message for same displayed while i was on the above error page. I selected the "check battery" option from that pop up and got my way out via factory "Backup and Reset" option under settings.
I hope this might help few people if not all! But the XDA forum is great and everyone will find a solution here. Cheers!!!
So I got this wm8850 chinese generic tablet. The camera is in the front in the middle (wide). It was shipped to me with 4.0.3 in boot loop. I soon found out that it boots into safe mode when I usb to pc. This is the furthest I've gotten with it so far. I can adb into it and have already tried to wipe data. It seems like since its from factory screwed up that a may need to reload the firmware or the os or something. Im kind of a noob because I only have my droid x. I've gotten it out of a boot loop before but I also knew what I had done to cause it so I fixed it. I tried to follow seks adb commands but im too noob to do it I guess. I was able to wipe data and dalvik-cache. Issue still occurs . If anybody can give me some adb commands than can help I would greatly appreciate it. Im fairly sure that I found the firmware elsewhere on xda. I thank you guys for any help at all you can give. I don't wanna send it back without trying everything software related as I can, but ill send it back if I can't fix it or if I brick it
Sent from my DROIDX using xda app-developers app
i have same problem in my china mobile.. dupad k1 ... after in installed new boot screen, device stuck in boot... please help to recover my device in step by step....
I've had this phone for 6 odd months now. It was cheap and it was both a phone and tablet in one. Apart from the camera data being deleted somehow it has worked fine up until last night.
It crashed and went to reboot randomly and got stuck in a boot loop. Seeing as it is a very uncommon phone, (I'm certain I am the only person with one in the whole of New Zealand) there are no custom roms and anything at all. So there are no custom recoveries.
I was going to look up make one but that is pointless with it stuck in a boot loop. I have tried going into stock recovery and wiping cache. No change, so I factory reset it. No change. I let it sit, off to let it die completely and clear cache/factory reset
I'm at a loss at what I can do. I really need the phone going but to my knowledge I cant get it running. I'm hoping some of the smart minds on here can help. I will provide any detail/media that people may require if they have any idea what to try to get it going.
Thanks for your time

Here is my full story
I have a huawei y300 with no Os, how did the OS got wiped? I was in twrp and was doing a factory reset where i select advance reset and end up wiping the entire system alone with my files, Os, apps etc... after which when i turn on the phone it wont boot up.
I then realise that i could still access twrp so i search everyone it but could not find away to restore my OS and solve the problem, bare in mine that i rooted the phone.
At that point when i plugged in the phone and search for adb devices my phone was shown after a few research and attends i failed in fixing the problem. I then did something while using the push function to send clockwork recovery to the phone or something like that after which i realise that twrp stop showing on the phone i then realised that i was not seeing my devices on the list of adb. after a few attempts and i kept on trying i saw it came up as offline but now its not showing again.
Hope you all understand the issue now
So like wat i need is a software that can program the OS straight to the phone is such software does exist but in fact should because how the OS came on in the first place, i dont know a thing about phones but i know a little to help myself but i have reached my limit
Please help
I have been reading everything I can find and tried to figure it out myself but the more I read the more questions I have and the less sure I am about trying any of the things I have read.
My problem is with an lg tribute from the company called Textnow. My friend ordered the phone from them and was having some issue she decided to try to fix by doing a factory reset which caused it to be stuck on the Lg boot logo. I tried booting to recovery to fix it. The recovery was TWRP. I was under the impression that Twrp was a custom recovery program that was installed after unlocking boot loader. Best I can tell is the phone was already rooted by the company. Does this sound right?
I messed with it for while but couldn't get anywhere with it because I haven't any knowledge of rooting except what I read . I noticed it kept saying something about simulating actions and figured that out but now after trying to back up and restore and poking around that it says there is no os , I was hoping someone could help me figure out where to go from here as it isn't my phone and I would hate to damage it although my friend keeps telling me to just try whatever no big loss because she can't use it like it is so.
I am not sure what the phone had for firmware because I cant get it on. I only know that it had twrp 2.8.5.0 as recover not the usual android. I can access the phone internal and external through twrp and though pc and adb. I made sure to get drivers updated. I tried to flash the stock rom from its forum but it failed,. any info would be mush appreciated
HI All
Have a Honor 7 PLK-L01, stock ROM, never modified in any way, now stuck on boot logo. Windows 10 pings to say phone is connected but nothing visible/accessible on computer.
I can enter boot EMUI screen with 3 options. I know I can try factory reset etc. but really need to recover some data on the phone (contact numbers/texts/pictures).
Any advice on the possibilities of achieving this?
Searching I have come across the Android Data Recovery Toollkit (drfone.wondershare.com/android-data-recovery.html)
Anyone used this, does it do what it says on the tin?
Any other software/services people can advise for me to access my data?
Regards
Hello,
Annoying situation, not really much you can do.
I don't even know if you could use that drfone recovery toolkit in the EMUI recovery.
Your best shot is to take out the SD Card and recover some from there, if you're using one.
If you meant using the recovery toolkit after you do a factory reset, you might still be able to get quite a few images and videos back, but the important part is that you don't record any other videos or take any other pics meanwhile.
Also don't download anything or don't watch any videos either, because that will overwrite the deleted files and corrupt them.
But then still, you have the problem that you need your phone to be rooted if you want to recover anything, which is very hard at this point for any Huawei device, since Huawei doesn't let you unlock the bootloader anymore.
Not really much you can do, sorry, good luck anyway.
