[Q] How to repair/unbrick Android Tablet? - Android Q&A, Help & Troubleshooting

Hello,
I Got a question about the tablet. I experimented a bit with the settings and I adapted the tablet one file in ROM (Data / system / etc) vold.fstab.
Unfortunately tablet not working, only show android logo and then nothing. In recovery I got it, wipe data / factory reset and wipe cache partition but without result, that result is the same.
Is there any way to copy original file or modify the edited file in ROM?
I suppose some way by cable and ADB, Google wants to help me somehow ...
Firmware unfortunately I do not and I did not find him anywhere.
It is a tablet with Rockchip RK3188 -> 3Q RC1025F
Sorry for the translation...

Doesn't seem like the company itself has the firmware available for download on their site. You might want to contact them directly:

[Q] help slidepad NG 808 bricked

Hello everybody,
I'm new on this forum, and you are my last chance. I searched for a long time on the net, but nothing can help me. I bought a memup slidepad NG 808 a year ago (MID rk2918-based, 8" screen, HDMI, 1024 Mo RAM, 6470 Mo stockage) and i wanted to change the ROM because of the low of the official ROM. I searched how to root the tablet, i found and rooted it. After that, i tried to find files to install custom ROM in the tablet. I found a zip from OMA, and i tried to install the ROM via Rkandroidtool. But i made two mistakes. Mistake one, i don't make a backup of the original ROM (oups), and mistake two i don't install the ROM adapted to my tablet specs. When i reboot the tablet after install, the odys loox page appears ont he screen, and after the OMA screen, whith the lightning , appears, but the tablet freezes. I must push the reset button to make reboot the tablet. I can access to the CWM , but anything else. My question is, is it possible to reinstall a ROM from the CWM, and if it's possible,where can i download the file. If it's possible, i would want to install a custom ROM, but if it's not possible, the official ROM works well.
Thank you to welcome me to your forum,
Hello,
I searched on the net, and found some people who has the same problem than me, but no one can help us. I tried to connect my tablet to a ubuntu PC and i have access to the microsd content and the backup file stored in the storage memory of the tablet, with several files in .img. I imagine this is possible to replace this img files by non corrupted files and reboot the tablet. But where can i find this files?

[Q] My Guophone I9600 android 4.2.1 is fully bricked. can someone help me, please?

Hello,
I am contacting you to see if someone can help me.
I have a Chinese phone. It is a Guophone i9600, MT6589 CPU quad core 1.2 GHz with 1 GB RAM.
This week it began to continuously display messages “memory full” and it told me to uninstall applications. I looked in settings options and it really showed internal memory was fully occupied ... when it wasn't true. There aren’t no applications installed nor data (including whatsapp app).
I restored the phone to factory defaults and it worked well. Now there was a lot of internal free space. After this, I installed lnk2sd app and I started uninstall applications that came with me smartphone ... but the phone has been bricked.
When I turn it on, it hangs in the original logo GUOPHONE. I don’t have any backup.
My laptop doesn’t recognize it. I have downloaded MT65xx drivers and when I try to connect the smartphone, it tells me not receive reply from the peer (I guess it will be smartphone). Therefore, I can’t use all that solutions that need to connect mi smartphone to my laptop (flash tool, CWM, TWRP, ROM manager ...). I think the only solution is to load a ROM file in ZIP format from the factory recovery menu.
I searched ROMS and I only found one in needrom.com (for Guophone I9602 (I guess you can be the same as mine, i9600)). I've downloaded it from a web page link and a mirror link, and one is a single file with img extension and the other one is a .rar. I have unzipped it and it has a few files with extension tar and img. I've tried everything, zip them, unzip them, renamed file extension... and nothing have worked.
I have also tried to generate a zip with the two img file (I think they're called recovery and boot) as someone said in some websites and it didn’t work. They said I have to include a META_INF folder, but I have no idea where to get it.
I have even located the manufacturer's website, I sent them an e-mail to ask them smartphone`s ROM zip file and they didn’t reply me.
One more thing, I bought two identical phones, one for a friend and one for us. Is there any way to get from me friend’s smartphone a file from ROM ZIP file to use it in our smatphone from recovery menu?
From my friend's phone I have downloaded (in "backup user data" option from original recovery menu) a file with backup extension. But when I try to restore it in me phone, it shows me a checksum error.
Thanks in advance. Excuse my poor English, please.
Best regards

Use DroidTool to to copy ROM from your Friend... i realy need that stock ROm .. i have same phone but i cant use it because i bricked and i dotn have ROM.

Can i edit the wifi section of an *.img with Dragonface??

Hi.. I have been trying to fix a tv stick for a few months now (basically is more about the knowledge i am getting - I am not desperate in fixing it). It is a strange piece, probably clone that i have been tricked in buying. It has an Allwinner A20 dual core cpu with an AP6210 wifi module...
Tried to flash another firmware ti improve it, ended up with the wifi problem. Wifi (and bleutooth) will not start. When i press the button, it just slides back to off... I have read and tried anything i could find on the internet. I have also tried tens of firmwares, but the wifi problem persisted (the original firmware is nowhere to be found).. To cut the story short, the device will not connect to a computer through ADB (it just doesn't seem to support this function - is not a matter of drivers). So everything i have been trying did not include this option...Also the recovery can not be changed to support backup and restore from custom recoveries (i.e CWM, or TWRP)..
What i did manage was to extract a backup from the rom, of another identical device, with the Nandroid App (online version, not through the recovery). Then i used the Dragonface program to edit another similar firmware (MK808C). While loaded, i open the FSOP folder which is the folder that dragonface collapses the loaded firmware for editing and then, i replaced the existing system folder with the one i had backed up trough the Nandroid procedure... Then hit the save button of the Dragonface...
I flashed the new *.img to my tv stick with the phoenix tool, and the tv stick booted normally, looking EXACTLY the same as when i first bought it. I even managed to get the bleutooth going this time, BUT, the bloody wifi still refuses to come on :-/
I must tell you, I know my way through some computer technical stuff but I am not an expert into the coding level and i haven't had the experience of Linux systems (thus i don't really understand coding). I really thought all settings and drivers are included in the system file and copying the original system file into another firmware, would do the trick.. but i guess is not that simple... The thing is that, the way i see it, the problem is probably hidden at the booting level... hitting the system configuration in the advance settings of the Dragon face, will open some coding thing which i don't understand.. but i do see the AP6210 module in that coding, which means that the new firmware includes those drivers..If anybody have any idea or can point me to the right direction I would really appreciate it.. Thanks
I have the same problem with AP6210 on H3 Allwinner STB box. After firmware ugrade from Android 4.4.2 to Android 10 Wifi just don't work, button slides back to off. Drivers are present. Have both firware files unpacked.
Please help! What i have to do? Sys_config? Init.rc?

(Re-post :) RK3126 - yk98vq-rk3126-v2.1 - Over-bricked ! (Yes, it's possible :D)

(this is a re-post of a new thread in a wrong section, thank the Merovingian who leads me here ! http://forum.xda-developers.com/general/xda-assist/rk3126-yk98vq-rk3126-v2-1-bricked-yes-d-t3505962 )
Dear people all over the world, it's from far far away I write to you !
I tried to change the /system partition of the tablet, after several "auto-reflash" of the partition (the system on reboot deleted always my job), I flashed again and came directly in the "Loader" mode.
I don't know how, the parameter partition became altered, begin with a double "..Param..Param" and made the system unbootable.
From now, I wasn't able to write on the parameter partition any more.
Worst, I don't know how, the tablet start now in a MASKROM mode... The IDBLOCK and nandinfo are not available any more (not downloadable).
All software like "upgrate_tool", "batch tool" "android tool" "rkflashtool"... can neither upload data, nor download.
But the system still recognises the PID and VID (0x2207 & 0x310d), and the flash manufacturer (Samsung), it means, he can still communicate with the µC.
Is there still something to do ?
All ideas are welcome ! (From JTAG reprogramation, re-soldering to simple HW manipulation like pressing 2seconds the reset button ^^ I'm an adventurer ! And I can easily access to a small well provided lab...)
Wish you all the best,
me

Zebra TC-51 rooting or Possibly custom firmware help?

I have a zebra tc51.
I have all the images roms , reset files etc
Iv been trying to root the device for such time
Iv tried it on android 6.0.1 and android 7.0.1
Unsure if it's possible to root or allow much via the update.zip ( images of the device ) using there update-script
Reasons , debloatware it, we use our devices to emulate NFC to access doors etc for the functions we need , we change a lot of the operating system on our other devices to have. Better user function and ease of access , some functions and features of our software we run don't work due to having no access to parts of the system we have a device we can hardly use I have a another device with 5.0.1 from zebra but it's a older one that is rooted but it dose not have the hardware support we have
If someone is happy to help me unlock this device I'm happy to help pay some kind of support for your effort or send you a old zebra m40 something (haha)
But endless web hours on this topic for me , been looking at editing the update.zip
And allowing root support but I'm unsure
It's going on eBay shortly
TC51
I have a zebra tc 51 and tc70, both of which I have to unlock/reset to factory. Could you provide me with the files you have for your tc51? It would be greatly appreciated.

I reset TC 51 successfully a week ago. Just go to zebra site under support for mobile computers and then into android 6 OS and the third "+Full Image"
and download: Atlas_Ent_Reset.zip. place in a FAT32 SC card in root dir, hold down power and scan (top left) buttons concurrently til logo. Select flash via SC card and hit power. 6 min later, full reset to all default apps.

Hi, Sorry for not being more clear regarding the file I mentioned above. The reset file I stated to download and flash to phone is not a firmware image for the TC51. It is a file that when applied to the phone via updating from the SD card. It is instructions to the phone to commanding it to hard rest itself. It is a very small file, I dont remember, but I think like 15mb, whereas firmware img files are far larger.
The are to versions, one being enterprise - it will reset with enterprise partition not being wiped and the non enterprise reset file will wipe all.
8 or so minutes later, you will have a TC51 booted into its default state, apps and all. Any passcodes locking it are cleared. The above enterprise/nonenterprise reset files are available for google services or none.
Once you click the one of the full image "+" symbols to expand the subtree, you will see the files I mention. You will also see the full image files you are asking about but you cannot download them without permission.
Sorry for the long msg, but one last point is, the small reset files that do not require password verif to download, I guess basically the phone is reset as if the stock rom was reflashed to it, but without the img flash. I did this week ago and works well. I am new to this forum, joining only to state the easy reset of the TC51 and have not seen any rules as to what types of uploads are permitted here, if all cool, I can upload the files here.
Hello
I am also in need of the 6.0 or 7.0 firmware pls nd thank u
My guy you are freaking money. I have been trying to unlock mine for like a year and have constantly gotten stumped.
Thanks very much for the help. Sending massive good juju your way.

I think I may have misunderstood. I thought these files were for rooting. Not just for resetting. It will still be nice to get a copy of them though.

Were you ever able to get root access? I am in the same boat, I have reached out to Zebra for assistance in unlocking the bootloader but they have not responded.
I did search in the software license which (according to their site ) says:

I have not written to them on this matter through snail-mail. Perhaps that is the next step. As an indie dev its was hard enough to get access the the software revisions. I had to jump many hoops and it took over 6 months to get access the GMS and non-GMS versions for Marshmellow, Nougat, and Oreo.
