How to update or reinstall my Android phone's Android - Android Q&A, Help & Troubleshooting

Hey there
I am using this phone called Gionee CTRL V5. I couldnt post the GSMArena link as I am a new user here.
I got it from a friend. He installed a custom ROM of Android 4.3.3. He is out of town now and I cannot ask for his assistance.
I am finding slight bugs and lags with this custom rom. Can anyone help me install either the stock 4.2.2 or Android 4.4 on this phone?
I am a complete newbie to Android. So it will be great if anyone could help me out!

Make sure the device is rooted before going forward for custom ROM installation.
This new Android 4.4.4 BSZ KitKat custom ROM has to be installed on the Google Nexus 7 (2012) model only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >>*About phone >>*model number]
Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
Users make sure they have installed USB drivers on the PC, or else your tablet (Google Nexus 7 2012) will not be recognised by the computer.
Make sure your device has more than 80% battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.

[Q] Virgin (ZTE) Awe ROM?

Hi there,
I just obtained a new Moto G which I am planning to use from now on, and I decided it would be beneficial to root my old phone -- Virgin (ZTE) Awe (N800) -- and try to gain some experience in the field of development. Mainly, however, I just wanted to upgrade the OS. I successfully rooted the phone using Kingo Android root; then I went on to try to install Cyanogenmod 11. However, it said my phone was unsupported.
Next step -- do it manually. So I downloaded the Android SDK and tried to get ABD running -- with no luck -- as I was trying to use abd sideload to load the OS file for Android 4.2 (but for Nexus 7). However, with failure after failure of trying to load abd, I has to ask myself: Will I brick my phone?
So, any thoughts? Are ROMs phone-specific? Can I get a better ROM for this phone? Would I brick it if I tried to load another phone's rom?
Any help/advice greatly appreciated!

ROMS are phone specific do your research google your phone virgin mobile awe n800 and after you type that just type xda there are roms for uour phone but after you root you need a recovery make sure your sd card will be sufficient to hold all of your backups and data

[Q] how to install android from scratch literally

Hi,
Currently i am struck at a situation where i need to do a fresh install of complete rom. The problem is as below
I own lenovo A6000 which is new in indian market with firmware kraft-A6000. I was frustated with the custom vibe ui given by lenovo and i started to install custom rom. So i booted temporarily into CWM and installed some other lenovo ROM which resulted in disaster. I have restored it back by using the backup taken using CWM. This restoration lead to complete failure of the phones signal reception. I mean literally cell is not able to register to network and catch any signals. So i got little bit frustated and booted into CWM temporarly using ADB and Fastboot and formated system files. (/system). I was aware that it will compelete wipe up the system but one thing which i was not aware that time was i haven't flashed the custom recovery over stock one. So now i am stuck at a point where i cannot install custom ROM zip through stock recovery since signatures and firmware mismatches are happening. I cannot fastboot the phone using debug mode as my stock rom is wiped off completely and my device is unauthorised when i listed it with "adb devices" command. So I came to the conclusion that i need install the stock rom zip using the stock recovery. When i googled for it, i could not find it available and got git-hub link for the same firmware code. So i am hoping to rebuild it into zip and install it using stock recovery.
After good effort of search, i am still left with questions as well as confusions.
1. Is there any way to make my device autherised and make signature check OFF using adb commands so that i can install custom rom -- my guess is probably no, but please confirm
2. I some how got the code of Kraft-A6000 ROM from git-hub and from lenovo site. I would like to know the steps (or any links if already posted) on how to make a zip out of it using linux shell or using eclipse without installing android sdk studio. (i am a bit skeptical as i saw in some of the xda forums stating the code is not building properly as it is missing some files but just wanted to give it a try myself)
3. If any pre-loading methods exist that factories use to install android for first time please suggest.
My last option is to go for a lenovo service center and check with them if they can get it back working but i really want to give it a complete try before going to them.
Note: i am not a core linux user and to my knowledge i tried my level best to resolve the issue myself. Please do also let me know if any extra information is needed. Any help on this is highly appreciated.
How the hell was this posted in 1970.? And can you share the source links you find with me.? I'm building my own source right now, but a completed one would be helpfull

Nabi Big Tab 20 Stock Rom Request.

Long story short I modded my stock rom and only made a backup after I removed a bunch of system apps I knew were safe. Well youtube stopped working and my children like to watch you tube and Nabi release an update to patch their system to fix the youtube issue but I can not flash due to missing system files. Looking for stock unupdated or even updated rom for the nabi big tab 20 and help would be great. TWRP is the only recovery that I am aware of for this tablet.
Thanks in Advanced!

Still Needing That Stock Rom?
I kinda did the same thing. So I just bought another Big Tab 20 to flash TWRP and backup the stock rom. I must mention at some point the Twrp Backups did not restore properly on the previous device. Dont know what happened. Im scared as hell to do this because it seems like theres no turning back to stock and this one cost me a cool $100.
Where I may find the stock rom or TWRP backup for this tablet?
I bricked this, just doing root and rename launcher and chrome apk in system folder, after this I get a bootloop.
And I need pinout a nabi connector, don`t have a usb cable..
Bringing this back from the DEAD
Hello,
I just got this Nabi BIG TAB HD - Model on device is bgtab-nv20a.
I am able to access recovery and select to wipe it, however when booting into Android it will ask for you to connect to the internet, regardless if you do it or not, a message will appear not allowing me to proceed, the error will be that it cannot connect to the FUHU server or that it cannot perform update and therefore cannot continue.
I am looking for either a way of rooting and flashing a custom ROM or simply get it to boot with the already installed Android system.

Huawei ShotX / Honor 7i (ATH-UL01)Android/TWRP/BOOTLOOP/XPOSED Problem(STUCK IN TWRP)

Hello and i wish you all a good Day and i really appreciate the time you are giving to help me.
But before i Start, here the Data about my Phone:
Name
Huawei Shot X / Honor 7i runs actually on Android 5.1.1 & EMUI 3.1
CPU
Qualcomm® MSM8939™, Octa-core 1.5 GHz
Operation System
HUAWEI Emotion UI 3.1(on Android™ L)
Root: Yes
Bootloader: Unlocked
TWRP: Yes
So, this gona be a little bit complicated as you can see in the Titel that i got 4 Problems at the same time so i complety messed up. I'm sitting here 2 Days and Night trying to work on my Phone and im so desperate that i created a Account here.
And the site also says, no low quality Questions here and i guess that's not a low quality question because theres less then 5 Theards/Questions about my Phone. Another Point wich makes it so difficul to can fix all by myself. But to get all things clear i will tell what i did and how it started, because im still confused after Hours of Searching and downloading.
It first started whit Pokemon Go I wanted to Install Xposed on my Huawei Shot X, so i can Play the Game while im in Brazil spending my Holidays. But the First Problem was, that the Modules was not compatible whit my Xposed. I had Problems such like XposedBridge.jar. Or when I read about that the Version 2.7 would fix it i had a Problem that Xposed was not compatible whit my processor Architektur. So i searched till i found those links:
http://forum.xda-developers.com/android/general/guide-workaround-running-xposed-t3338765
And especially before my Phone nuked i followed this Link (Click on "Link").
I already noticed that to Install Xposed on my Device will be Tricky on a Huawei, it's not like on a Samsung where Hunderts of Tutorials and solutions ect. Fast i noticed i need TWRP. Sadly i found nothing really matching whit my Phone i downloaded over here, over there img 3.0.0 all didnt work well or not correctly till after Hours i feelt trolled finding Twrp in the App Store. And while my Search i found a Guide giving me a Link how to Install TWRP on my Huawei Shot X. They linked me to a Download for TWRP Huawei G8 wich i did. The Download didn't worked but the App on my Phone did pretty well an installed Version 3.0.0 for Huawei G8 (like the Guide sad). I trusted the Guide because theres no Guide, especially for my Phone. So it looked like the Huawei G8 might be the only and closes Choice. I fail to install a File Manager from a Indonesian Devoloper and i know there are newer Version of TWRP but i didn't wanted to run risks. I had Install the Huawei Driver on my Pc and runed ADB but i can't remember in wich oder anymore because of the huge stress. TWRP started succesfully, at least that but when i noticed something is missing, i wanted to move some files for to install Xposed correctly. Andoird didn't started anymore . It wasn't a actually "Bootloop". TWRP Starts till now all the Time and it's functional but i didn't get "into my Android". I saw some Codes ect that i can entre in CMD , something about ADB that would make it possibel to get into Android again. After all, nothing was deleted, the Data was still there (I made a Back Up on my PC before, so no Problem). But there was no was to get into my System. So i tryed to take this as a Chance to install Android again, but better as Android 6.0 and i found this Update (Click on Update). This Update didn't work i get a Red Clored Text and the last Zip i tried to Install Android 5.1.1 for Huawei ShotX EMUI 3.1 fom the Huawei Site, TWRP sad the Files are corupt. And i aslo tried a Guide from "HighOnAndroid", explainding how to install Android 6.0 from TWRP, wich didn't work too. Im finding no probly ROM wich match. I finding nothing really compatible or working. Not a simpel way to install Android on my Phone im just stuck in TWRP. I hope for someone how give me straight/save links for my Huawei Shot X about how to Install Android 5.1.1 & EMUI 3.1 and if it's possibel to install maybe Android 6.0. And of course, the Reason why this Chaos just started how to install Xposed. Perfectly would be to Connect my Phone to my PC and a Programm wich simply installs Android. Thank's for helping and you time.
PS: A really other Important Point, theres no Data on my Phone anymore Expect TWRP and some failed to install Zips.
PSPS: 2.6 Xposed wasnt working to..
No anyone?
At least tell me how to install Android from TWSP
dear friend.you must flash stock recovery through fastboot then install stock rom
I got it fixed by just flashing the stock recovery.

Alba 5 - Global Android?

So my LG broke. In the meantime until i get a new proper phone, i bought a cheap off-brand android phone. However, when attempting to root it, i bootlooped it, and like an idiot; i realised i forgot to make any backups of any partitions. So my question is, are there any universal versions of android i can flash over using the abd that will make the phone work again?
Thanks
No each kernel for the device is built just for it. You will need to stock room from the oem. Good luck as normally it is not available
Alba
I have an alba 10" ac101cplv2 and have successfully rooted it with super su but can't seem to find a custom ROM for it. Would like to install twrp but unable to find a version for my tablet. I'm hoping that someone could point me in the right direction. Just a cheap tablet I know but would like to open it to new possibilities like using SD card as storage for apps like have done with my s5 mini that runs beanstalk 7.1.2.
Can not root Alba 5
Does anyone know how to root Alba 5, i'am finding it really difficult. It is on Marshmallow 6.0 i have tried many rooting apps and have attempted to root through pc and through the phones recovery mode. Also when i go in to recovery mode a broken android logo comes up and it says something in chinese under it. The phone still works perfectly fine would really appreciate some help thanks.
