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.
Sek
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.
Bump
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

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

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....
Hello,
I have a Asus zenfone 6 however my problem also occurs on the zenfone 5 phones.
The poblem is as follows,
After updating from stock to latest android (v1,18 at the time) the phones battery display became incorrect making the Phone unreliable at bestand nothing seems to help fixing the problem.
I have tried a million calibratnig apps with zero success as suspect the phones software doesnt actualy understand that it has a 3230 mah battery.
I have found and compared files with a working zenfone6 where the file displays 2070mah for me and 3230 for the working Phone.
I then tried to manualy change this file had no acces even with root but every reboot or unplug it just resets the file anyway as it gets its data elsewhere.
I have tried a factory reset but not everything was actualy reset it just deleted my data but roo and all othr crap that the update screwed up was still there.
I tried ADB sideload but that didnt work and udupdates as ota so will not factory reset and remove root anyway.
I contaced asus but they are as clueless as a goats rear and just say a future update will adress it...Which we al know isnt going
to happen as this has bin a issue for some users for over half a year and they didnt fix it.
So as a final attempt to fix this Phone im planning on unlocking the botloader which i really didnt want to do as im new to all that and just want a rooted stock rom...
So to my question.
If i unlock the bootloader i know the Phone will be wiped. Will i just be able to flash any version of the stock rom via ADB or is there other things i need to do to either the Phone or the rom?
I cant go screw up my Phone without knowing how to fix and flash it again directly.
And do apps like the one asus provide usualy also allow relocking of he bootloader again after flashing the rom as i dont want to leave it open if there is no need to?
Any other ideas are welcome aswell but i have bin trying to solve this for over a month.
Heres a screenshot of the error i get when i try to reflash current rom with ADB.
http://oi60.tinypic.com/2eefzuv.jpg
But as long as that doest a full clean rom install its not helping me anyway.
i really hope someone has a easy and quick way to do a fresh install that will really make the Phone like it was just out
of the box software wise. no root no changes or anything as factory reset is not doing that for me.
Thanks in advance.
Hutjeflut.
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 hello
So here’s a head scratcher I hope someone can help me with that won’t involve replacing my main board.
Got myself the p20 lite (ANE-LX1 C432) - Single Sim.
I unlocked the bootloader with Huawei just before they stopped handing out the codes. All was good and happy with the world.
Rooted with Magisk and Was busy messing around With Termux, Linux deploy, Mobile Terminal and some pretty basic stuff. I’ve been out of the android scene for a while so was getting reacquainted with the scene.
Anyway. I was messing around in the terminal in a root shell just fixing basic permissions after messing up my termux environment as root. Phone randomly rebooted (I must’ve messed with the wrong folder -no idea which) came back on and my IMEI and baseband were gone.
No worries, I thought. Happened tonnes of times with my previous Devices (looking at you Samsung) just a quick restore or flash and all will be happy again.
Yeah, not quite.
Note that up until this point I hadn’t touched the system partition (probably besides the mobile terminal mishap -no idea)
So over the last week or so I have tried everything. Restore from Twrp backup. Flashed stock through fastboot, through erecovery. Those flashed ok but didn’t fix it.
Putting numerous different update.app FULL & OTA updates in dload folder on SD and internal all failed. Only used my builds version of course and only ones firmware finder deemed compatible/available
Then I got desperate (read: stupid) Decided to take the unpacked firmware files and flash whichever ones twrp would let me. First tried just the modem files. Didn’t help. Then just went through the list and flashed all I could.
I think the kicker came in when I installed the Trustfirmware.img because once I did that I rebooted and now I was stuck in an endless boot loop. No way to get into recovery. Not with their ton combo nor adb/fastboot.
I still had access to fastboot at this point at least and started doing every single thing suggested all over the net just trying to get back to stock.
Tried the unbrick option on The Huawei Multi-Tool. Flashed ok. Phone still wouldn’t boot. Did it a few times with 3 approved versions. Nothing. Only access to fastboot otherwise I was in a boot loop with error mode error no 15 and the verification failure (Attached below)
Last thing I tried after reading online was to relock my boot loader and flash stock. So I locked it with Huawei Multi-Tool. Reboot......
Now I don’t even have access to fastboot. My PC’s (windows and Linux) don’t even acknowledge it and holding volume down in all the weird and wonderful ways and times does nothing. All I get is startup Huawei Logo, Error Mode as per pic Below and then reboot. That’s it.
I’m assuming it’s trying to do a factory reset after relocking the bootloader (if it even locked properly, can’t check) but it can’t get into recovery/erecovery. I dunno ?
That’s my essay of where I’m at. Warranty is already void so not an option and I don’t want to buy a new mainboard (may as well buy a new phone).
So here I am. Is this my life now or does anyone have any magic tricks to possibly suggest?

Thanks for this.
The battery discharged fully about two days ago.
I haven’t tried plugging it in and out as/if it turns on immediately (though even though it shows dead without charger it still comes on immediately).
I’m gonna get a weaker lower amp charger and see if that maybe helps. Fml ?
***UPDATE***
Been at it for hours. Battery is completely flat. But h second I plug it in the the Black Huawei logo comes up ten a few seconds later it’s on the same error screen for a little longer then boot loops like that constantly.
The error isn’t the same as the post in that link though. And I am FRP unlocked.
Eh.

I guess your previous error was related to ramdisk...
Now what is your current situation?
-What error is showed in the Error mode?
-Can you reach FASTBOOT&RESCUE MODE menu?
-What is your current recovery?

As it stands I cannot enter fastboot or recovery mode. Update from SD also doesn’t do anything. Battery is completely discharged. And if I leave it on the charger it doesn’t charge, only boot loops.
So with all that the ONLY thing this phone does now is:
- Starts up Showing Huawei logo
- Error Mode Screen with Func No: 15 (bl31 image) & Error No: 1 (security verify failed)
- Reboots
Ths happens whether it’s plugged into the pc’s usb or the charger. Tried all combinations of buttons too.
It has stock recovery as I flashed that back when trying to revert back to stock.
I lost access to fastboot after I locked the bootlaoder again using the Huawei Multi Tool. It’s like it trying to do the factory wipe that it usually would after locking/unlocking the bootloader but is unable to due to the error mode screen.

I see, it is really bad
My last hope is to be able to do a forced Firmware upgrade. Press power button and VOL + and VOL- simultaneously. Do you see the same as the attached image?

Ah man, I wish it would even do that. It makes no attempt to even pretend to see the sd card update. If I hold all the buttons in it still only comes up with the error mode and reboots.
I popped it open and connected a charger up battery to see if that would help but it doesn’t.
Do you maybe know the pin layout on the inside or know where I could get schematics? Been looking everywhere.
I’m almost done building my own Jtag box and am hoping to bring it back to life by writing straight to the damn thing.

That is sad!!!
With JTAG and schematics stuff I cannot help you.
What I found recently and it was new for me (I didn't tested yet) is a possibility to install firmware via "dload" folder, but to start installation the stock recovery have to be full functional.
If I found something interesting for you I'll post here.

To my knowledge the recovery is installed. Well erecovery. It was working up until I locked the bootloader again and it went into a boot loop instead of doing the factory reset.
Is there any other way to force sd update other than with the dload folder?
Thanks for tying to help, I appreciate it.

You can check the official documentation about that.
Please let us know how you solved this problem.

Still unsolved as of yet.
I’ve finished building my own version of the Riff/Octoplus box as well as a makeshift Jtag. I’m still trying to find and piece together some firmware files and other board software I think I need.
Also, if anyone has any idea where the test point is on this board I’d really appreciate you pointing it out. I cannot find the schematics or any solid documentation anywhere.
I will attach the pics I have of both sides of the board as soon as I get home.

well, try to restore your device using dload method. It needs you to copy the UPDATE.APP in dload folder of an external sd card(formated in NTFS format) and then just press both vol up+down along with power button for a few seconds. It will auto launch huawei e-recovery and will try to flash the UPDATE.APP you stored in ext sd card. This should definitely work.
Dload method doesn't need you to unlock your device or bootloader.
Maybe?
I know it’s a long shot but I still have this phone. If anyone maybe knows if there’s been a way to fix this as of yet please let me know. ?
Lol. Still got this damn thing. Been searching around and seen a few people reporting similar errors. Never find out if they ever solve it though.
So. Anyone maybe have any knowledge to share? Anything at all.
I don't know if you still have your device, but I had the exact same issue with a P10 (VTR-L09)
I was able to fix fastboot using https://github.com/mashed-potatoes/PotatoNV
That tool was designed to unlock the bootloader, but I noticed that It actually flashes a slightly modified version of fastboot.
PotatoNV can also unlock P20 lite bootloader, so you should give it a shot.
Good luck!
If it works, you should be able to flash stock recovery image and then restore the system using the dload folder.
you can Repair it with Software Testpoint and Full Bootloader Unlock ,and then flash a Board Software via Software Testpoint, that helps 100%!!!
use this Firmware Download ANE-LX1
use the Software with logins and you have all what you need.
you must start the Software Testpoint so!!
VIDEO : how to start Software Testpoint P20 Lite
than in Software Testpoint you flash the included Board Software with DC-Phoenix and after that use the included dload update via sdcard and eRecovery mode and your Phone is running!!!
I would unlock the bootloader via Software Testpoint with DC-Phoenix, then the FBLock is unlocked and you can flash as you wish!!!! And the great thing about it is that you don't need an UnlockKey either, you can then read this with HCU client software, the only thing that's stupid is that you need a time-based license for the two programs, which you have to buy.
HCU client download
https://hcu-client.com
DC Phoenix download
https://forum.dc-unlocker.com/forum/modems-and-phones/huawei/155916-dc-phoenix
Since I accidentally bought a 3-day license twice and my P20 Lite is now completely rooted on Lineage 19.1, I can give away 2 access data, which are still valid for 2 days.
you can edit your smartphone with it.
