Rooting Allview Speed City

I was looking for a budget tablet with decent hardware (except for the screen which is crappy) so I settled on the Allview Speed City. This tablet is similar to the Chinese Onda 701 with the small difference that the Speed City does not have Volume Up/Down hardware buttons. The same hardware may be marketed and sold under other names in various countries, so check the specs before attempting to root it.

The tablet is running a custom ROM based on Android 4.1.1 that includes some bloatware (like an antivirus) next to the standard apps. Fortunately, it has a recovery ROM that lets you install zip files, so, it doesn't appear to be fully locked.

So, as any power user, I wanted to root the tablet and be the master of the software installed. Problem is - there was no known root available when I bought it.

Note: before proceeding make sure you understand the risks of rooting, and also be advised that you may lose your warranty.

Rooting instructions for the impacient

So without much ado, to root the tablet, you will need to follow these steps:
  1. Download the root + google apps package: http://www.mediafire.com/download.php?bbuqt6rwxou7cw2 (if the link is no longer valid drop a comment and I will re-upload it)
  2. Unzip the archive downloaded above (Root_Gapps_complete.zip) to an external SD card in the root of that card. You will get two files:  factory_update_param.aml and root.zip.
  3. Plug in the SD card into the tablet (the procedure requires an external SD card; internal storage doesn't work).
  4. Turn off the tablet
  5. Turn on the tablet in recovery mode. You do this by holding the HOME button and the POWER button pressed until you will see a big green android on the screen. You can release the buttons now. (the screen looks like the following image - sorry for the quality)
  6. Once the update is complete, the tablet will reboot automatically and you will get a message "Updating system apps". Once it's finished, you are rooted (if Superuser is not installed, you can install it from the market).
  7. Profit! :)

 The emergency ROM

All Android devices have a recovery ROM that allows you to unbrick your device if tragedy strikes. For the Allview Speed City you can enter in the Recovery ROM by holding the HOME and POWER buttons pressed at startup. You will be presented with something like this:



Since unlike the Onda 701 you do not have hardware keys for Volume Up/Down, you'll need to use the HOME button as DOWN ARROW and the POWER button as ENTER.

Other than that, the Recovery ROM is pretty functional.

As vrea sa pun un o versiune mai noua de android ( ea are vers 4.0)

Salut,

Am rootat tableta, dar am facut o prostie.. Am instalat un dpi changer si acum nu mai porneste. In recovery mode, cand apas pe "home", imi stinge si imi aprinde ecranul, asa ca nu am cum sa navighez prin meniu. Ma poti ajuta, te rog, sa o deblochez?

Pe threadul de discutie de pe xda mai era cineva care se plangea de acelasi comportament in recovery. Teoretic, chiar daca busesti partitia de date nu afectezi recovery-ul si nu ar trebui sa se modifice modul de functionare al butoanelor.

Eu am incercat sa vad daca pot sa o bootez in recovery intr-un fel incat HOME sa-mi inchida ecranul, dar nu mi se intampla. Ma gandesc ca e posibil sa fie un bug - cateodata sa nu mapeze corect butoanele, asa ca mai incearca sa dai reboot si sa retestezi...

O alta varianta ar putea fi sa incerci sa conectezi o tastatura usb printr-un cablu otg, dar n-am testat

Eu eram persoana de pe xda.. Aseara m-am mai documentat putin si am incercat sa fac un zip flashabil, dar cand se instaleaza, imi da install aborted.. zip-ul este semnat cu un programel, dar nu imi dau seama de ce nu merge.. In zip am bagat fisierul build.prop de la Onda 701, ar fi bine daca as gasi unul de la Speed City.. zip-ul de rootare pe care l-ai pus la dispozitie cu ce este semnat? ma gandesc ca de la certificat sa fie problema cu instalarea..
crs said…
Functioneaza tastatura in recovery, dar din pacate factory reset nu a rezolvat problema.. Se pare ca tot prin metoda cu zip-ul trebuie sa incerc.. Acum doar sa fac rost de fisierul respectiv original. Tu detii Speed City?
Adrian Popa said…
Nu am experienta cu tableta respectiva, dar ideal ar fi sa aflii care e firma chinezeasca care o face si sa vezi daca au ceva rom-uri mai noi.
Alta alternativa e sa incerci un AOSP sau CyonagenMod, dar exista riscul sa nu ai drivere pt tot hardware-ul si sa nu poti folos wifi, bluetooth sau camera.
Orice ai incerca fa un backup nandroid al romului curent sa nu plangi dupa el...
crs said…
pai cum ii fac backup daca nu o pot porni?
Adrian Popa said…
Da, e mai greu sa faci backup acum, dar teoretic iti pot trimite o imagine nandroid a sistemului. E posibil sa o poti flashui prin adb in recovery.

Zipul de rootare nu stiu cu ce a fost semnat... am presupus ca nu a trebuit sa fie semnat...
crs said…
ok.. Mersi. Ai adresa mea de email in al doilea comentariu.. Te rog sa imi trimiti zip-ul acela..
crs said…
Salut,
Te rog, ma poti ajuta si pe mine cu zip-ul acela? Multumesc!

Man...dar ce root e asta ca vad prin comentarii ca daca instalezi unele aplicatii se blocheaza tableta :|..
Adrian Popa said…
Dupa ce faci root bunastarea tabletei e doar responsabilitatea ta :) Root iti da posibilitatea sa faci ce vrei, inclusiv sa te impusti in picior :)
Eu, personal, n-am avut probleme cu aplicatiile instalate dupa root...

Salut,eu cand sunt in recovery mode pe Speed city nu ma lasa sa dau in jos cand apas pe home button.
Adrian Popa said…
@Robert: Nu merge întotdeauna. Încearcă să intrii în recovery fără un card microsd conectat și fără cablu USB conectat. După ar trebui să-ți meargă tasta.
Baftă!

Buna! Am o tableta Allview speed city si am apasat pe cele 2 butoane pana cand mi-a aparut ce trebuia sa imi apara pentru a alege :)) Problema este ca nu am tasta volume up si down ca sa o manevrez iar cu celelalte 2 butoane(home si power) nu prea cred ca functioneaza deoarece am incercat si nu a mers....Ce trebuie facut in acest caz? Si pe ce sa apas ca sa pot sa-mi aleg optiunea dorita?
Adrian Popa said…
Ca să poți naviga în recovery trebuie să folosești tasta Home. Ca să selectezi folosești Power. Am văzut că tastele pot să nu funcționeze dacă pornești în recovery cu un card SD atașat sau cu tableta conectată pe USB.

Deci, intră în recovery fără card SD și fără cablu USB și ar trebui să meargă.
Unknown said…
Cand apas pe butonul home imi apare un fundal negru dar luminos ca si cum ar trebui sa apara ceva dar tot nu apare si dupa ceva timp de stat...nu inteleg..exista alta metoda?
Adrian Popa said…
@Gabrii Ela: Deci când intrii în recovery nu se vede nimic pe ecran? Sau se vede, dar se stinge ecranul când apeși Home?

Alte metode nu știu (din păcate recovery-ul lor stock nu are adb să poți intra așa).
Dacă chiar vrei root în situația asta poți încerca să flash-uiești ROM-ul de la Onda (pentru v701-v5). Am impresia că vine root-at (dar nu l-am încercat). Dacă nu, ar trebui să poată fi rootat cu aceeași metodă ca în thread.
Unknown said…
Trebuia sa spui si ca dupa manevra cu Root_Gapps_complete.zip se schimba versiunea de android, nu doar rooteaza tableta. Daca ar fi doar rootul s-ar putea reveni la versiunea unroot, dar asa ai un android 4.1.1 cu baseband version 2.1 bulid number sv1.1 fata de version 2.0 build number sv1.0 cum era. Asa ca nu mai ai speranta de garantie.
A facut cineva rost de varianta originala pentru ROM ?
Adrian Popa said…
@Prong Man: Nu am fost atent la modificările de versiune raportate, dar din experiență proprie ele apar pentru că se modifică build.prop. Cu un editor de build.prop poți să rescrii vechile valori (în mod normal fără nici o consecință).
Unknown said…
@Adrian Popa: am incercat sa intru in bootloader fara card si fara cablu date in tableta. La fel. se face ecranul negru cand apas butonul home. Daca incerc reset din setari se inchide total. Alte solutii?
Adrian Popa said…
Hmm, din pacate n-am alte solutii - poti incerca daca ai o tastatura usb si cablu otg, dar nu stiu sa mearga...

Home Assistant + Android TV = fun

Here's a quick setup guide for controlling your Android TV from within Home Assistant. I've used it to control a genuine Android TV (Philips 7304) and an Odroid N2 running Android TV. For this to work you need ADB access. It can usually be enabled from within Developer Settings. The great part is - you don't need root access! The most important things are described in the androidtv component for Home Assistant: https://www.home-assistant.io/integrations/androidtv/ Make sure you go through the adb setup. My configuration is simple (inside configuration.yaml): media_player:   - platform: androidtv     name: TV Bedroom ATV     host: 192.168.1.61     device_class: androidtv Once Home Assistant restarts, your TV might require you to accept the connection (adb authentication). This happens only once (or until you reset your ATV to factory settings). Once running the integration will show you the current ATV state (on or off) and allows you to turn it on or off.

SmokePing + InfluxDB export + docker + slaves + Grafana = fun

I've been working for a while on this project - with the purpose of getting SmokePing measurements from different hosts (slaves) into InfluxDB so that we can better graph them with Grafana. The slaves run multiple Smokeping instances inside Docker so that they have separate networking (measure through different uplinks, independently). This will not be a comprehensive configuration guide, but a quick "how to" to handle setup and basic troubleshooting. It assumes you already know how to set up and operate a regular Smokeping install with or without slaves and that you are fluent in Smokeping configuration syntax, know your way around Docker and aren't a stranger from InfluxDB and Grafana (sorry, there's a lot of information to take in). 1. Getting Smokeping with InfluxDB support - you can get it either from the official page (most changes have been merged) - https://github.com/oetiker/SmokePing (PR discussion here: https://github.com/oetiker/SmokePing/issues/

Installing Home Assistant Supervised on an old 32bit HP laptop

 I've received a challenge from my former boss: an old HP laptop that was born in 2005:  an HP-Compaq NC6220 ( https://www.pocket-lint.com/laptops/reviews/hp/68181-hp-compaq-nc6220-notebook-laptop/ ). The specs are abysmal: So, i386, 1.7GHz single-core CPU (remember those?), 1G of DDR2 RAM (2x512M) and a 40GB ATA (not SATA!) drive. But hey, at least it has a serial port!  The challenge is to install HomeAssistant ( https://www.home-assistant.io/ ) on it so that he can monitor some Zigbee temperature sensors and relays (via a gateway). The first hurdle was to remove the BIOS password - following this nice guide: https://www.youtube.com/watch?v=ZaGKyb0ntSg Next-up - install HASSOS. Unfortunately, it doesn't support i386, but only x86_64... So, I went the Home Assistant Supervised route, and installed Debian 11 i386 edition from a netinstall USB ( https://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-11.6.0-i386-netinst.iso ).   Once Debian was up and running (didn't
