well in the file of the ROM there is all u need to install the rom

ROM - SP FLASH

but there is no the PRELOADER DRIVER so u need to download the other Flash tools to install just search it inside the folder and install it

and a couple contacts in the top ( for speaker maybe)

i'm going to see what i can do with it

Any one that has posted a review of this tablet? I'm considering to buy this one but not many reviews out there. I had the A1000-F but because of the USB port I have to update and planning to stick with Lenovo.

i been using it for a out 1 year and it can handle everithing

SONIC RACING sinc the last update is not woking but i dot play too much so is not a problem to me

But my little cusings does so i have instaled a few games to let them play

i use it mostly for reading and broswing , FB , Camera, Mail Checker , music

adn like a mini laptoy i just attach my usb cable via OTG and works just fine

and as u can see u got everything to mod it ( if u r thinking aboit do it ) u got ROOT RECOVERY UNBRINK

and w hope that some developer add to this an try to compile a new rom for it ( i'm learnig how to complile to but its goint to take a wile cuz mediatec devices are a little bit tricky to do some mods, but are cool and u can test if u want cuz if u kill it u can restore via the UNBRINK precedure

the sound is not pretty loud u have to set a ew value in ingeniering mode and u get better sound and louder

( i'm goit to post how soon so if u want to buy it and u want to do so.. ))

Drivers not working

When I try installing the drivers on my Win7 64-bit machine, it says there are no drivers available. When I've gone to the device manager and found the Lenovo device, it states that no drivers are currently installed. I've tried telling it to update the driver and manually pointed to the unzipped folder, but it says no drivers could be found. The end result is KingoROOT doesn't see the device, even if debugging mode is enabled.

Any ideas?
[Android General] Zoidiano0:
well u need to install not only compressing and setting the folder

u need to install it from the .ini file so u can install it as android adb devices

i think it says android debug bridge or something try to install it that way and

it would be ok

if not let me know ;)
[Android General] Zoidiano0:

[Android General] terra_zg:
Hi everybody!

I wonder if any of you with rooted Lenovo A5500F running Kitkat 4.4.2 can create and send me a backup (like Titanium or similar) of 4 Lenovo system apps - LenovoID, Lenovo Weather, Lenovo Weather Service and Lenovo A8-50

I'd like to return my tablet to it's original state, but have accidentally deleted those .apk files, and now factory reset cannot reinstall them :(

[Android General] KokaiBalazs- dev:
OK, so I have figured out this tablet... .

So to install custom ROM on it do:

Install kingroot apk(on the website)

Root it using that

Install twrp official app(on the website)

Flash the recovery.IMG(on the website)

Download a ROM from there: https://balazs-kokai.github.io/

Download the fix-boot.zip from the website

Reboot to recovery using twrp app or hardware buttons

Wipe: Dalvik ART Cache, Cache, Data, System

Install the ROM what you downloaded

After that install fix-boot.zip

Install gapps (additional)

Reboot and enjoy!
[Android General] bumba1:
i have that tablet but its not rooted and dont wish to root as use for sky-go so please advise best way to make firmware copy and i will try to help
[Android General] terra_zg:
:good: :D

Could you please check if your ROM build number is A5500F_A442_000_029_150408_ROW

Anyway, even without root you'd probably be able to locate and send me the relevant apk/odex files if you have ES File Explorer or similar tool on you device (at least, I can do that on my unrooted samsung device). This might be a trial-and-error procedure, as I've never done it before, but if you're willing to try, I am too.

And thanks for the offer, whatever comes out of it :P

Stock boot animation

Hello,

Could you please upload the stock boot animation of the Lenovo A8 A5500-F?

Cause last night I changed it and was kinda excited and didn't back up the stock (Original) boot animation either I renamed it to : bootanimation.zipbak

The bad thing is that the Rom Toolbox Pro didn't warn me that I'll lose it and that I need to make a backup. And I kinda want the original back so it wouldn't missing from my tab.

Although is there any problem if it will be missing or there could be any problems in the long run? Cause after a reboot last night it jammed on the lockscreen but I've pressed sound button down (-) & power button and it rebooted normally and it seems to be working just fine. I would appreciate if someone help me with this. I also need help in couple of other things and I can help with any files that someone may need from this device.

Thank you in advance ☺?

the factory reset does nothig to the system partition so if u have root an install xposed framework its going to fail

i used to have the same problem so i copy the update file from the sd card ( or whatever is placed ) and open it an and edit the update-script file

by deleting the security checks

if u can please upload the update file

and i can show u the lines that u need to edit and to have a backup of the file to use for other people
[Android General] Zoidiano0:
its the same problem that i have

i try to flash he system with flash tool but not work stops at 28-33% and never works that i did was buy a new mainboard

hello i am facing challenge with the drivers can you please give me the files, i have tried so many versions even from mtk but the drivers are not working. On the tab i just need to root it only??? or i need to put in recovery?
[Android General] Zeitkind:
Well, yeah, anything other than the broken original 4.4.2 ROM would be nice. Lenovo never fixed the WIFI problems many owners have. I tried several access points, tried proxies, tried without WPA/WPA2, tried with IPv6 off, .. still no luck. After a few minutes WIFI keeps dropping off and using the tablet is just a pita. As there will be no new ROM from Lenovo (and no Andoid 5.x) I already decided that this will be my last product from Lenovo. But I already have 3 of those A5500, so any progress will be nice.
[Android General] Zeitkind:
Finally found a solution for my constantly dropping wifi connections.

After searching for months now and trying _a_lot_, I stumbled upon a post somewhere about a different model of Lenovo - and a fix. Seems that Kitkat & Lenovo has a problem with AES encryption and WPA2. Switching to the more unsafe WPA & TKIP my connection is now stable for several days. I use an old Dlink AP for this and it is connected to my DMZ network. For I use this tablets just for surfing the net and such, it's not a problem for me to seperate that WPA/TKIP-WiFi and my Lenovo A5500's from my LAN.

But a newer firmware would be nice nevertheless - prob. with a fix for this AES-problem. Many newer home routers and access points can't switch back to the older WPA/TKIP-encryption, so it's a fix - but not for everyone I guess.
[Android General] tagilbo:
My daughter in law has updated the a5500-f (untouched) and the process is failed. (switch on->lenovo logo->android figure with some red something- with "no command" line under it.)

Now can't boot the device, but it can reach factory-recovery.

The MTP, and fastboot not work. (code 10, the computer cant't reach the tablet).

What can i do with it?

Maybe it have ADB-connection. Isn't some update zip, which i can push to device via adb?

Sry for bad english.

Thanks.

[Android General] Canary5:
Zoidiano0, you are awesome. Just fixed my wife's bricked tablet. Had to figure out how to install a driver without signature first, and then plug in the tablet AFTER the flash tool did its initial stuff.
[Android General] nannycrick:
Hi guys! I'm new to this forum but not a noob. my last tablet was the bigger sister of this tablet.....the Tab2 A10-70F rooted & smoothed thanks to Tzul & folks over at that forum. my beloved baby met with an unfortunate accident. I bought this A8-5500F off of Craigslist for $75 with a nice fitted case and no issues. I rooted it using Kingroot, then app!ied the SuperSU conversion. No problems but.... can't get bootloader unlocked to install TWRP!

I can tell you from my experience that the most important step to "hacking" a MTK device is the installation of the unsigned drivers. Here are driver download links for Windows 10 x64 and x32....

http://tehnotone.com/windows-10-mtk-vcom-usb-drivers-for-32-64-bit-drivers-installation-tutorial/

With drivers correctly installed, you'll be able to crash, reflash, customize, reset your A8 until the proverbial cows come home! I've been able to reset, revert, downgrade my A10-70F tons of times using the latest SP Flash Tool. Don't worry about a bricked tablet cause the SPFT WILL unbrick it ....IF....the drivers are correctly installed. Good luck guys!
[Android General] nannycrick:
I have one question......

How do you unlock the bootloader in order to install TWRP recovery. I have root. I used King root , then ran the conversion to SuperSU. Everything works BUT......no unlocked bootloader via adb.

Tried the adb command... fastboot oem unlock which didn't work. TWRP won't install unless there's a patched bootloader flashed first . That's what I had to do for the A10. Any advice or ideas.

The running info....

build....A5500_442_000_029_150408.ROW

rooted success w/ SuperSU 2.65 Pro installed

Busybox Pro installed.

Flashify installed.

TWRP WILL NOT FLASH THRU FLASHIFY!?! Stumped!

Nevermind! The bootloader is already unlocked, and the TWRP recovery I tried wasn't correctly ported.
[Android General] nannycrick:
Did some research into the TWRP issue. It isn't for the A8-5500F s/n 59407798 tablet running A5500_442_000_029_150408_ROW. Either the porting was done incorrectly or not for this particular tablet. Still rooted & looking for recovery.
[Android General] nannycrick:
Okay.... here's the result of my experience trying to get root & twrp installed in my A8-5500F....

Use Zen Tool to do initial rooting but unhook before the SuperSU install. You just want King root. Then hookup to MTK Droid Tool and let it read the device. Push the ROOT button when device info shows in window on left. Let it do it thing. If it asks to create CWM recovery, say yes. If it asks to patch the bootloader say no as it isn't needed. Download the Easy Magic TWRP Installer by Yuweng from XDA. Open the download, with the device turned on. Run as administrator the TWRP.exe. It will auto port your recovery to TWRP. Reboot into TWRP, set your settings, make a backup. Have a much better day! Enjoy! Here's a link to the Easy Magic installer

http://xdaforums.com/showthread.php?t=2798257

Was able to install Xposed , Viper4AndroidFX by GuitarHero, Sony Walkman Player ported by Ibanez, Fonter module, KitKat write fix module, Flat Style Keyboard module. All working beautifully to custom tweak this baby!
