[eBay.ca] Refurb Kobo Arc 7 HD w/ adapter and original box/ $40+$10 shipping! (w/ rooting guide)

https://www.ebay.ca/itm/Kobo-Arc-7-HD-7-16GB-Android-Tablet-With-NVIDIA-Tegra-3-Processor-Refurbished/162751871391

https://www.ebay.ca/itm/Kobo-Arc-7-HD-7-16GB-Android-Tablet-With-NVIDIA-Tegra-3-Processor-Refurbished/162751871391

The seller is highly rated. The price is $10 more than historical low, but the historical low DID NOT come with the Kobo official box (some even reported no adapter), so there was no way you could give it as a gift. This one, despite costing $10 more, has both adapter (2A) and original box.

Here is a detailed root + customization instruction written by me, follow it step-by-step, i.e., word by word, line by line, don't skip anything.:

I finally figured out this tablet, enjoy, guys!

Kobo 7 HD (K7H) is probably the cheapest (so far) FHD tablet that you can get in the history of tablets, I bought mine (refurbished 16GB, but appears to be brand new) a couple days ago for around $40 CAD.

Here are the steps I took to make my K7H into a bookreader with full browsing capabilities with a superb battery life.

***start of preparation***

(you need to re-perform preparation if you screw up and brick your K7H at any time during this guide)

download mfastboot-v2.zip from here

https://androidfilehost.com/?fid=95916177934532795

if this link above expires, google mfastboot-v2.zip and i am sure you can find a valid one somewhere.

the zip is 1.36MB and should contain the following 7 files:

AdbWinApi.dll
AdbWinUsbApi.dll
linux-fastboot
mfastboot.exe
osx-fastboot
aapt.exe
adb.exe

**extract all contents to a new folder on your desktop, let's call this folder HOME folder from now on.**

next, download

http://download2.kobobooks.com/apollohd/update-ota339.zip

if this link above expires, google update-ota339.zip and i am sure you can find a valid one somewhere. it is 382MB.

and copy/move it into HOME folder

fully charge your kobo

reset your kobo by pressing the power on (PO) button and then immediately pressing the volume down (VD) button, you should then be brought to K7H's system recovery interface, choose wipe data / factory reset by pressing VD twice, and then press PO. then pressing VD 7 times until you are at "Yes", then press PO again. then wait for it to finish.

next connect your kobo to your PC with the USB cable that came with K7H. on K7H, press VD once to select "apply update from ADB", press PO, and you are brought to a waiting screen, at the same time, the computer will install necessary drivers needed. on PC, hold down Shift key and right mouse click in HOME folder and select "Open command window here" (make sure you don't have any file highlighted), in the command window, type

**adb sideload update-ota339.zip**

this should bring you to this screen within the command window on your PC

https://i.imgur.com/WxsAxGH.jpg

one comment: feel free to disconnect and reconnect K7H to your PC a couple times if you encounter error messages such as "error: device not found" "daemon not running" etc after you type adb sideload update-ota339.zip

on K7h, it will install the firmware and a couple of yellow lines will appear and the final yellow line should say "Install from ADB complete."

https://i.imgur.com/JhWHt2U.jpg

next, reboot system now should be automatically selected, simply press PO to restart your K7H.

***end of preparation***

your K7H will be stuck at the Kobo screen for a while, be patient. once your tablet is booted up, you need to go through the whole registration/update process. this part doesn't require any guidance, although it may appear you can only do this with a kobo account, so register one on your PC.

once you are in, press the bottom right icon to go to apps, select settings, scroll to the bottom, select

"about kobo arc 7HD", tap on "build number" 7 times to activate developer options.

go back to settings by press the back-up key at the bottom left corner, scroll to bottom

select "developer options"

checkmark "USB debugging"

uncheck "verify apps over USB"

go back to settings by press the back-up key at the bottom left corner, scroll to bottom,

select "security"

checkmark "Unknown sources"

uncheck "verify apps"

now download **tr_old.apk** from here and save it into HOME folder.

https://forum.xda-developers.com/attachment.php?attachmentid=2843562&d=1404980556

if this link above expires, google tr_old.apk and i am sure you can find a valid one somewhere.

on pc, hold down Shift key and right mouse click in HOME folder and select "Open command window here"(make sure you don't have any file highlighted), in the command window, type

**adb install tr_old.apk**

again, feel free to disconnect and reconnect K7H to your PC a couple times if you encounter error messages such as "error: device not found" "daemon not running" etc. please note that, you can use this method to install WHATEVER app onto your K7H, even ones not meant for android 4.2.2, as long as you can download the apk of the app, you can get apk of apps by using google or from certain reputable sites like https://www.apkmirror.com/ or https://apkpure.com/ or https://www.apk4fun.com/ and etc.

now go to apps on K7H, open the new app towelroot, press the "make it rain" button and wait for K7H to reboot, **now your K7H is rooted.**

now on K7H, search for **SuperSU** by CodingCode from the google **play store** that you can access by going into apps (again, press the bottom right icon to go to apps), sign in using your google account, it should be the first result returned. please note that, your Kobo might restart on its own, as it is busy updating all kinds of softwares now that you signed into the playstore, as its CPU is quite slow and is easily overwhelmed. once things settle down, open SuperSU, press start, choose continue when it asks for binary needs update, choose normal when it asks the other question.

next, download **recovery.img - [Click for QR Code] (6.54 MB)** from here into HOME folder.

https://forum.xda-developers.com/showpost.php?p=47024957&postcount=4

assuming your K7H is still connected to your PC, on PC, hold down Shift key and right mouse click in HOME folder and select "Open command window here"(make sure you don't have any file highlighted), in the command window, type

**adb push recovery.img /sdcard/**

then type in the command window

**adb shell**

then type in the command window (make sure the screen of your K7H is turned on)

**SU**

a box will popup on K7H (i.e., look at your tablet), make sure you select "GRANT"

then type in the command window (by the way, you can always right click and select paste when you are in the command window)

**dd if=/sdcard/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS**

Next, in the command window press Ctrl key and C key as if you are copying something

then type in the command window

**adb reboot recovery**

now your K7H will restart

you will notice that the interface is different from earlier during the preparation step, "reboot system now" should be highlighted, press PO button, press VD 7 times to highlight

"Yes, disable recovery flash"

then press PO button.

**now your K7H has the Recovery Mod.**

next. search for nova launcher from the play store that you can access by going into apps

(again, press the bottom right icon to go to apps) and install the free one.

once it's installed, press the HOME folder button of your K7H (middle button of the three virtual buttons on bottom left), select Nova launcher and make sure you select Always.

now go to play store and search for **titanium backup** install it. run it and select "GRANT".

go through some menus where you always press "OK".

if you ever get stuck at the Kobo screen with three dots for a while, just connect K7H to your PC, hold down Shift key and right mouse click in HOME folder and select "Open command window here" (make sure you don't have any file highlighted), in the command window, type :

**adb shell input keyevent KEYCODE_HOME**

please note that the above command is case sensitive, i.e., KEYCODE_HOME must be capitalized

last thing, the screen is really bright at night, even when i adjust the brightness to minimum. so i figured out a way to adjust it further. install **f.lux** either through adb install or through app store, change the color driver to **tegra** and you are good to go.


if you are an advanced user, you can use **titanium** to uninstall A LOT of things.

i am not advanced, but through some trial and error, i managed to delete a lot of things, such as the drop down menu when you swipe at the top, and a lot of other things. doing this helped me extend the battery life to 10 days ([2 day 14 hour * 4](https://i.imgur.com/YNBwXMk.jpg)) with daily book reading and / or light browsing before bed, the standby battery life is around 20 days.

the system navigation bar also takes up a lot of screen real estate with its default status bar(top) and navigation bar(bottom), the difference is night and day, compare the following two images:

first is on a K7H where I got rid of both the top bar (no need for it really), and bottom bar (replaced system UI with [this app](https://play.google.com/store/apps/details?id=com.dogusumit.ortatus&hl=en))

second is on a regular K7H.

(don't pay attention to the large font, I set my text to large under accessibility)

https://i.imgur.com/WsH7IDC.png

https://i.imgur.com/HrcMsC7.png

the top bar and bottom bar together take up around 13% of screen real estate by my calculation.

btw, I learnt how to take SS of your tablet screen under adb (the above 2 SS are not taken with a camera like earlier), hold down Shift key and right mouse click in HOME folder and select "Open command window here"(make sure you don't have any file highlighted), in the command window, paste the following code and the screenshot should be under your HOME folder.

adb shell screencap -p /sdcard/screen.png
adb pull /sdcard/screen.png
adb shell rm /sdcard/screen.png

here is a SS of K7H running Moon+ Reader Pro

WARNING do not buy. These are double refurbs. Kobo originally fixed these returned tablets to sell
Them, some were lemons and didn't work. They resold these total duds to this company and they quick fix fixed them and now are selling them. Source : I called kobo and gave them a co workers doa tablet Seriel number,

RETURN shipping will be ur problem if u get a dead unit.

Some users report not getting ax adapters or usb cables

Software limitation and ancient and may no longer be supported



AVOID AVOID

Regularly goes on sale for $29.99 or even lower if u catch the 1 day sales.

My co worker is filing a cc dispute because this company is making her pay for a doa lemon and then 20% restocking fee. Very poor experiences do not give to ur co workers or anyone as gift please.

Your instructions provide Root capabilities, do you know of any ROM of higher Android version?

Also, do you know if Netflix works on the tablet after rooting?
I'm looking for a tablet with the Android version 4.4.2+ for offline Netflix download capability.


Thanks for the detailed guide

See post quote below, you probably need to use the adb install method mentioned in OP to install netflix. I recommend following the instruction in OP line-by-line, as my set-up at the end is pretty spectacular (maximized screen estate, before vs. after)

Did root and remove lot of stuff + nova, flex, etc Does it make the tablet not sluggish? No. Does it make less sluggish? Yes very much. Don't expect keep many apps open at all but for $40 after tax and ship? It's damn amazing even as purely netflix/ereader (but it can do more!). I bought one, arrived in two days, then bought two more was so impressed.

After rooting, removing stuff, etc though the battery life improved dramatically. Like easily 2x+ on screen and more then that in idle. Kobo app that is constantly running really kills the thing.

Netflix is horrible on this. Slow and choppy. Save your money. My screen has a yellow hue as well.

My experience is that it plays 4k youtube videos smoothly, i don't see how it's even possible to be slow and choppy with netflix.

You need to spend some time to customize your unit to make it snappier, this tablet isn't for starters, see the following post for reference:

Thanks, this looks promissing,

But how about offline downloading of shows/movies on Netflix
It is only supported on Android 4.4.2 and I think this one comes with 4.2.2

Have you ever tried it?

Compared to the prior listings: 30% more, shipping is also higher, not manufacturer refurbished, buyer pays return, 30 days warranty (vs. 1 year from Kobo the last time around).

For general usage, the Amazon fire is much better deal at $60 (2017 build, current OS, free shipping, free return, 1 year amazon warranty), unless you only need a tablet to use as a picture frame, there is a little good the extra resolution would do when you have to struggle everyday to keep apps running on it, as app support keeps on dropping for the ancient OS running on the arc.
