I'm trapped in a phone's uncomplete rom - General Questions and Answers

hi i have gfive g9 handset and i rooted it and installed recovery in it, it was working fine and i flashed some custom roms in it too, they all went fine.
but
until now, i found a custom rom and installed it, problem is that this rom has no file manager in it, no keyboard, only google voice keyboard which is not working
and this phone doesn't go in recovery mode by hard keys combinations, it has to rebooted from some apps into recovery then it goes into recovery.
and this phone also don't have gapps in it
so i'm stuck, i can't go in recovery, can anyone tell me how can i access it's adb shell from my pc and give it command to reboot in recovery please?

You know there is a guide in the same section where you posted your question.

[Q] [HELP] How to back up stock rom (& upgrade) for UNKNOWN brand tablet

Hi guys.
I've recently bought a android tablet,
the brand was MBI and the model was i7
(which is a not known brand ... can't find much info about it).
In my quest of rooting it, I've lost the bundled disc (with Win32 driver). after reading up tons of articles. I've decided to download google's USB driver and edit the .inf, the the tablet's VID & PID info. Somehow I managed to get adb working.
And for rooting, I've tried .apk and none of them work, then I proceed to SuperOneClick and it hung. Lastly I've tried the Easy Rooting Kit by ZoomLord and ta-da, my device is rooted!
Then I attempt to back up the stock rom in case of anything. But Rom Manager kept restarting the device whenever I run 'Back up current ROM'. And when I try to flash the ClockWork Recovery Rom .. the only option was 'Nook Color' & version 3.2.0.1, even Rom Manager reported recovery rom flash successfully, but whenever I try to boot to recovery mode, CWR is not running... and default recovery image doesn't allow me to back up my rom either.
So, in short, I hopes any of you could help me out on following:
1) How do I backup stock rom? or get any recovery rom working?
2) After that, can I just flash to any custom rom? e.g., CM7 Gingerbread ROM? although my device isn't in their supported list?
any help will be appreciated, thanks.
Now I'm trying this fastboot,
somehow when I entered fastboot mode (hold Vol+ & power the device on).
"FastBoot" was showed on center of the screen,
but whenever I issue # fastboot devices
the device will reboot itself ....
any idea? I was trying to flash recovery image via fastboot here
hello
did you manage to root your phone as I too got this tablets thanks
I have a same problem too.. can't use cwm after rooting. Now my mbi i7 tablet can't be used anymore. It just show blank screen after boot up. I can't revert it back to factory setting because the rom is corrupted & the update.zip file is missing. Can anybody upload the update.zip for mbi i7 tablet please.. - sorry 4 my bad english..

Blu Elite 3.8 CWM Problem...

Hello Forum people:
I have a strange problem with my Blu Elite 3.8, aka karbonn a9.
I have followed the Karbonn A9 process of rooting and it worked perfectly.
But ater following the CWM installation to the letter I cant seem to get the phone into CWM recovery using the key combinations.
Things I have tried:
I've installed various versions of CWM getting the same results.
Tried different key combinations such as Power+Volume UP, Power+Volume Down, Power+Volume Up + Home
I can report a workaround, install CWM Rom Manager from playstore, then I open the app and it inmediatly wants to install a CWM version for your phone model.
Naturally I choose the last option: "Not Listed"
then the app asks if you have installed CWM manually, I choose yes.
I can now reboot into CWM via the CWM app but I really wish I could to this without booting into the rom itself.
Sure I can install custom roms but if i end up with a faulty/non working rom im screwed because i wont be able to use the CWM app to boot into recovery to flash a backup.
Any Ideas?

I need help with this tablet - few questions

Background:
I attempted to root the device. so I installed CWM... Well it doesnt stick. once you boot it never stays. When I go into recovery mode from the boot loader it says "no command" But if I flash it and then reboot right into the bootloader then go into recovery it works fine.
First issue: CWM doesnt stick
which led me to another issue..
ADB doesnt work in CWM (which I thought). So I decided to flash PhilZ recovery and found it didnt work there either! So I figured it had to be my drivers - but they worked fine in Windows and when the device is booted normally in the OS. (I am using Nvidia latest drivers)
Then I figured let me restore the unit back to the original image (i signed up as a developer) downloaded the Nvidia 1.2 Image and reflashed everything using fastboot (system, boot, recovery, data, etc.)
Since I had never tried to go into the stock recovery maybe it was CWM or PhilZ...
Leads to my next issue:
The stock recovery doesnt work no matter how many times I flash it. When I go into the bootloader and click on recovery mode I get "no command" with the andorid guy dead.
1. How can I get back the stock recovery using Nvidia's image. The recovery is not working
2. How can I get CWM to stick?
3. Why isnt ADB working in recovery mode but working fine when booted in the device?

All has been fixed except for #2. Cant get CWM to stick... but for 1 and 3:
OK.. got the stock recovery - I didnt actually know you had to do volume up when at the "no command" screen..
and also I figured out how to fix the driver issue...
For anyone else having the issue you need to uninstall the driver until it shows up as Shield with the exclamation. You must be in the recovery in an area like sideload.. (Not in android OS)
Then Update Driver, Browser and then click on "Let Me Pick from a list on my computer"... find Android then select "Android Composite ADB Interface".
Now the driver works in ADB and in the OS
Same Problem
I'm having the same problem with CWM reverting to stock recovery after system boot. I didn't see your post until after I posted my own thread -- I probably should have titled it specifically about the stock recovery reversion so others will find it. Anyway, not that there's at least one other person besides me having this problem, I'm less worried that it's just me being stupid. Although that's always a possibility. Maybe someone will come along and help.
Recovery Reversion Problem Solved
Okay, I solved my recovery reversion problem -- I wasn't using either a custom boot.img or the Beta SuperSu (currently BETA-SuperSU-v2.42.zip), one of which is needed to keep root on Lollipop. (Apparently I knew this a month ago when I first went to 5.0.)

[Completed] [GT-N7000] Stuck in manufacturer Logo, unable to enter recovery can enter download.

Is my device soft bricked?
I flashed PhilZ-cwm6-XXLTA-ATL-5.15.0.tar which worked, then I started up the phone and tried to flash CWM 6.0.4.3 touch using ROMManager, the process was a "success" but after the reboot attempt the phone was unable to boot OS nor is it able to go to Recovery mod. I am still able to enter download mod.
I tried flashing PhilZ-cwm6-XXLTA-ATL-5.15.0.tar again, but it didn't work. I can detect my phone in ADB devices and in Odin3. I am currently searching for a stock ROM for my device.
If anyone has experienced this before and knows the result already, could you tell me whether my device is lost or I can revive it somehow? Thanks in advance.
EDIT: My phone doesn't seem to go into recovery, stuck at manufacturer Logo(Not restarting); but in ADB devices I can see it in recovery mod and can see its contents in adb devices.
Solved: It booted normally after deleting update.img and cache via ADB.
Thread completed as user already founded the solution.

Hi I have tried so many times using the instructions all over the internet that says you have to use power volume up to get into recovery for flash mode but it never works just keeps loading into Android. Am I doing it wrong or is there a video or other way to get to stock recover. need to do this so I can install custom recovery and rom
Thanks

No you didnt do anything wrong. Some h/phone models do not respond to Vol+/- + Power. Out of the 11 device I owned my latest MTK powered phone do not respond to the hardware button.
But you did not describe your phone completely.
What SoC? Kirin, Exynos or MTK? (I assume it is MTK)
Are you rooted?
Do you want to access customs recovery or stock recovery?
If you are not rooted and on stock recovery, you can only access (for these problematic models) via "fastboot recovery"
command. It is not hard install adb driver on your PC, and your device driver. search for "fastboot adb" installer from the web. It is less than 1 Mb size and your USB cable from PC to device. End users cant do much when facing this problem.
If you are rooted and on customs recovery all you need to do is to install "Rebooter" from Playstore and click the rebooter from Android homescreen to get into TWRP recovery. (this doesnt work if you dont have root and on stock recovery).
I rooted , install customs recovery, by using fastboot and my device ROM flasher everything works well for me. And I enter TWRP via "Rebooter" and clear my dalvik and cache. Try it.
