Edit: OMG Kingo Root worked!!! (sorry guys, I was asking about root help for my zeepad 9xn and it had been about 3 years of struggling with this as no other solutions worked). Tried it once before, didn't work, I guess just recently it became compatible >o< soooo relieved.... OK You can still help me I AM still looking for a clean image that doesn't come bloated with malware. (yes malware, these built in apps which could only be removed by root privilage downloaded junk by the hour and popped up ads etc..)
A clean image would be very welcome for my tablet
Tablet info:
DualCore-a23
Zeepad 9xn
android 4.2.2
firmware v2.0.8
kernel
3.4.39
build: polaris_eng 4.2.2 JDQ39 20140325 test-keys
in recovery mode, it says Android sdk reversion: 2.2_r1-a23-v2.0
I have a Zeepad 9xn with a lost pin. I cannot get to the maintenance screen. I have pushed power + Up volume, little green light comes on screen stays black, tried power + Up and Down volume, same results, power and Down volume, same results. I can start it and it goes to the pin screen, I hold in the power it goes to shutting down screen with a choice. How do I get to the maintenance screen? HELP!!!!!

Firstly hey I'm new here Long time "lurker" & user of XDA for both Desire HD & Atrix
The RAZR HD I purchased off ebay is being a little dicky, I'll run you through the process
-- Unboxed , plugged it in , green LED light is on
-- Try to turn it on , LED light is gone and will not return
----End up having to enter recovery mode to boot into android
-- Phone works fine , installing apps etc ( used for about 6-7 hours)
--LED is working for sms etc
--Turn it off this morning to check that it is okay now (It's not).
So when i try to turn it on normally a green wind-up droid with a spinning blue sphere inside of it appears with a blue loading bar.... this goes on for a minute before the green droid appears on it's back with a error sign above it (The phone then turns off)
From there the only way i can actually turn on the phone is the hold power+Down volume and then switch to up volume to enter recovery which stays for a second and then boots up into a reset phone (Due to the hard reset of power+Down volume i guess?)
When it was running it was going fine!, I can't really be bothered sending it back & would rather fix it myself
I'm thinking the error has something to do with the battery? (e.g corrupted battery stats?)

Hey
I had this problem with 2 razr HD telstra phone after Updated to JB and after factory reset exact thin happened.they replaced the first one and sent the second one to repair.
Im 100% sure that this issue is with Telstra JB update.
I stl waiting for device!!!!
cheers
Would reflashing the Telstra JB Rom fix the problem??
[solved]
I had exactly the same problem with a brand new unused RAZR HD,
here is the solution (maybe for all RAZR phones?) [german]
I try to translate in a few words:
Code:
you need to hold down the reset IMMEDIATELY both volume keys
until the boot loader (I hope I do not rename the whole thing wrong now) appears.
In the menu that appears choose the recovery point, after which
first the screen goes black and then the Android males appear.
Now press again BOTH volume buttons and the menu (similar to the
ClockworkMod Recory menu) to reset the device is displayed.
[it took me some tries to figure out the right point of time]
Here you have the menu option to reset the data and cache
area [ I did this twice ]
and then perform a reboot of the Razr.
After performing these steps in the Bootloop kicked me on and
I could no longer continue with the set.
ATTENTION: When resetting all the data in the internal memory
(contacts, SMS, calendar entries, etc.) will be deleted ...
the Micro SD should remain untouched!

I think NO,
because there must be some error on data partition, flashing an new ROM afaik touches only the system partition
Hello guys, I got Blueberry Netcat M-25 as a gift on elementary school graduation, I like this device really, it is wi-fi tablet.
Specs link is attached!
So the thing I hate about this device is that it sometime crashes, like screen freezes and ANR dialogue pops up and says SystemUI not responding. Battery drains really fast.
So here is Kernel version: 3.3.0 [email protected] #1
Build number: fiber_q7s-eng 4.2.2 JDRQ39 20140312 test-keys.
So if you guys can find a custom ROM, and btw I have problem with going in recovery mode, i hold power+vol. down and when Netcat logo appears I hold vol.dn. key and nothing happens, just android logo and system loads. I would appreciate 4.4.x versions if possible. Thanks for feedback!
Hi
I'm using my phone (Lenovo A660) since more than two years.
Usually, I do not boot the phone to often (approximately once a month).
However, I recently realized when I turned of the phone, that the battery image is not shown when I charge my phone. Instead the screen is completely white.
When I booted the phone again, the screen remained white all the time until I pressed 3 times the power button.
Then my standard launcher (Hola) gets started normally.
However, the screen remains white when I start into bootloader mode or into recovery mode.
Hence, I cannot select anything in a menu (e.g., to perform factory reset or to wipe cache etc...), as I have only a white screen.
May someone has already seen the same behavior and knows where I can search for a solution.
Many thanks in advance for all tips that get posted
Compact problem description:
White screen under the following circumstances:
Charging while phone is off
normal boot until I press 3 times the power button (has to be done after the phone vibrates shortly)
booting into recovery mode (either with the keys or with adb command)
booting into bootloader mode (either with the keys or with adb command)
Information about the phone:
Brand: Lenovo
List item
Model: A660
Android: 4.0.4 Rom: Stock ROM with build number A660_S025_121122
Recovery image: Stock image or CMW
Kernel version: 3.0.13 #1 Rooted: Yes with SuperSU v2.01 Fastboot: not supported
Approaches tried so far:
flashed recovery rom with CMW and with stock ROM. No improvement
Change /system/media/bootanimation.zip and /system/media/images/boot_logo. No improvement
added and removed again "debug.sf.nobootanimation=1" in the file /system/build.prop. Changes at least that at shutdown an animation is shown or not.
resetted the /system/fonts folder with a copy of the stock rom
physically cleaned display contacts according to "Android Tablet White Screen fix" on youtube from My Tablet Guru
performed a complete dd image of /dev/block/mmcblk0 in order to be able to restore all partitons if something goes wrong
so far I spent approximately 2 days googling for related problems. However, may someone can provide a key word that I was missing in my search
I attached the output of logcat. May it helps at least to debug the white screen during the boot process.
Once again many thanks for any comment and suggestion.
Hi, thank you for using XDA Assist. You've tried a number of things and i don't have any further suggestions. It's most likely a hardware failure and I'm afraid you're not going to be able to fix it. You could take it to a cell repair shop and see if they have any ideas.
Ok
I think i have done it this time, my tells me not to mess around but i cant help it, anyway i decided to root my lenovo s856 to remove some of the preloaded apps etc and generally improve performance.

Asus Transformer TF 101… Was lying for a few years in the drawer.
Have decide to start using it for my daughter.
Had KatKiss rom 5.1 installed and was working fine.
Tried to upgrade to KatKiss 6.0.1 when troubles started.
Upgrade went OK but when was looking for the Google Play app (and service) and tried to install it, something went wrong…
At the moment, after spending a few hours with "POWER + VOLUME DOWN" and / or "POWER + VOLUME UP" I get stuck on splash screen with the KitKiss logo (the dog with the 4 balls) unable to do anything (trying to turn off, it starts automatically – the only way I can get it off is by letting the battery to runout) – Any advise would be appreciated !!!
I just got mine going again and had the same issue. I have re-flashed the latest ROM and the SU that was still on the system. GAPS is working but I am going to try to get something else on there like MicroG.
So re-flash it and see how it goes.
i cannot get into recovery.
Did you do it via ADX and ADB?
