My A850 is not reacting - Lenovo A850

Hello,
I have Lenovo A850 mobile. There was soft A850_203, which wasn't good translated into Polish and it was unable to mount SD Card(phone had not seen it). With FlashTool I upgrade firmware to the same A850_S203 soft from "needrom", everything was OK byt the SD Card problem was still there. Reading posts on forums I found that I should upgrade firmware to stock ROM. I did it wit ROM A850-Stock-S123, Flashtool ends with green light... and when I try to power on phone there was no reaction. I was trying with all buttons combinations and nothing. When I plug in the USB cable computer doesn't see my phone. I'm not able to use again Flashtool. Red light only appears when I plug in USB cable without battery. When the battery is inserted into the phone red light is off. I there possibility to fix this problem on its own? Thanks for any hints.

60% probability of softbricked(may bootloop), 20% hardbrick, 10% hardware prob and 10% USB port defected a bit. No possibility of fixing its own, you have to work on it.
Try seeking help from a local phone service, if he's unable to fix it via flashing (or somewhat identical), you may have to search for a JTAG professional, yes if it's HARDBRICKED.

[Q] Totally bricked XPERIA X10 Mini Pro (U20)

Hi there.
Yesterday, for no apparent reason de device stopped syncing my Gapps data. OEM 2.1 ROM. I did a backup and reset the device to factory defaults. Even if battery went to 100% and the USB cable were connected, the phone did not finished the process and now I have a non turning on mini pro. Mac does not feel it, neither Windoze or Linux with dmesg. PC Companion won´t see it neither. Neither FlashTool. I tried to flash it with the original ftf but the phone do not turn on and of course FlashTool won't see it. Tried pressing home and on/off but nothing. I searched like a dork for "bricked xperia x10 mini pro" but there´s a lot of crowd calling a semi-bricked, bricked. Which is not, because a semi-bricked can be repaired with SEUS or even FlashTool.
I know is a whole different animal, but once I bricked a Nokia and with some trickery the device came to life.
Guys, you`re my only hope. I really like this phone for texting and everything.
Thank you for reading. Best regards.
Bump!
Please help me out! At least tell me anything.
Thanks.

What do you mean?
When PC Campanion says "hold back key and connect phone to USB" then It detects the device.
I have bricked SE Xperia X10 mini pro, same simptoms phone doesn't react to anything it's absolutely silent, no image, no text.
And yes I tried SEUS, PC Companion, Flashtool (with ggsetup) and Omnius. Nothing hepled.
May be a battery is down but I can't check it as well.
Same here. The phone doesn't react to "off" button, No LEDs, no display, no sound, won't get recognized by Flashtool when USB plugged in with "back" held, a total, real brick, dark and dead and invisible to all software.
The battery was full - it was full when the phone got bricked by installing a kernel for ICS.

I have the same problem please help:crying:
When you put the tick called "preloader" in Flashtools - then the phone is dead... now only jtag method may can help you(in some phone service)
I remember that one morning I found my Xperia Arc S with stock GB 2.3.4 rom like dead although it was fine when I plugged the charger in before I slept. In the morning I couldn't turn it on, removing and replacing battery did nothing. No light when I charged it. It was really looking like it was forever dead. After a few days, in despair, I tried every reset method I could find about Xperia phones, except the one that finally worked:
I holded the back or menu button (I forgot which one) then plugged in the USB cordon to the computer. I got a green or blue light! I learned later that it was Fastboot mode or Flash mode. Then I unplugged the device, and it started like if nothing happened. I only had this problem once again. Since I rooted it and installed a custom rom, I never had this issue again.
If you didn't try this yet, that is worth trying

This is a clear guide
http://androidmtk.com/fix-huawei-ascend-g700-bootloop
it's for bootloop, but works for bricked also.
(obviously) Hints:
->Flash the RIGHT rom for you mobile
=>Flashing a wrong ROM or wrong PRELOADER results bricked mobile more difficult to unbrik, requires mobile to be open and access the so-known TestPoint on motherboard.
->Ensure your battery is charged enough
Maintain mobile connected to the pc until the end of process
May be you have to swith off Antivirus
Better run FlashTool as administrator (move mouse on file .exe, right click, run as administrator)
(please report if success or not)
Good Luck!
M.A.
P.S.: My mobile is dead now, I suppose due of static electricity of my body/jumper replacing ON/OFF & VOL+/- flex cables...:crying:
didn't work for me

maybe you have flashed wrong ROM. be careful not to confuse with ROW or CN rom. try press VOLUME UP + VOLUME DOWN and connect usb cable to your PC. works with mine.

Emish X700 Android TV box KK 4.4.04

Hi I bought on ebay android tv box called Emish X700. Once i went for holiday and disconnected TV box from power outlet. After 2 weeks i came back home and when i turned it on TV box get stucked with picture of dead android without any option. I tried to do reset with toothpick for 10 sec in hole but with no change. when i googled a bit i found tools and firmware which helped me to restore this TV box to factory state and to be able to use it again. That's why i'd like to share it with users with same or similar problem.
Firmware + Flash tools + Drivers
Steps.
1. download attached files
2. unpack it
3. follow instructions from document in "X700 upgrade" folder
4. in case your PC can't detect your device use "Android Tool" flasher with firmware from "X700 upgrade" folder
5. after successful flashing device will reboot and will be booting for about 15 mins, so be patient
Where can I find Android Tool?
I did the step but in the program for firmware update the label does not become Green, so can't detect the device
Android tool is possible to download from link in 1st post. to get green status in program you have to plug usb cable connected already to your computer to your box with pressed resset button for abbout 5 secs.
I did for 10 seconds but nothing happens
Edit: it work, thank you very much for the guide!!
need you help

You have to use the tool for flash, not the program where the label should become green.

I get the error IDB failed in android tools, what can I do?
Thanks for this! I've been searching everywhere.
Device not recognized using the tools.
I have an Emish 700 android box. Works great WHEN it's working.What I mean is that now and again the red light simply won't click on to blue? I've tried switching it off and on and disconnecting it, reconnecting it... over and over again. After a day or so, all of a sudden, poof it comes on blue when connected. I'm ready to throw it out and buy something new. I tried the tools above, but my computer won't recognize the device? Does it need to be plugged in and turned on showing the blue light to work? Thanks!
Thanks for the software and drivers, my device now is alive again.
for those who don't work properly the reset button, I was in the same situation, searching on google reset for RK3128 devices, I find a solution, do a short circuit between 8-9 Pin on NAND chip with the USB connected.
Install the drivers attached at the link from djmaj0, flash the update image with Android Tools, and now working perfectly.
PD: i flashed with Win10 x64 and no problems, don't need W7 or W8
Thanks again djmaj0!
After flash
After the flash, is the Android still 4.4.1? or updated to 5.0 or higher?
I have emish x700. However unable to identify the toothpick hole as no click on/off apparent. Im assuming the hole on back between the usb ports. Can you confirm this or where it is. My device is frozen on the emish screen and will not proceed further. Thanks

Yes you're right. The reset button is hidden in hole between 2 USB ports.

Hi. After flashing kitkat will remain as the rom is almost same as original. Unfortunately its not pre-rooted, but i have done it with kingroot app after flashing.

Thanks Djamjo
On my device unable to feel any pin through that hole. Saw posts elsewhere that you can use the on/off switch and volume control. Do you / any one know about this, also hole underneath the box whick on left out of line to other holes??.
Have downloaded the files. Can you confirm unpacking is same as extracting or unzipping ?. And as havent got to instructions yet do I need to copy the files to a usb or do everything from the laptop.
What is a short circuit between 8/9 pins on nand chip as advised above, and roughly how one would one do it.?
Sorry this is all a learning curve, hence delay. Thanks
For flashing firmware is required the DC-IN 5V to be connected?
So I found out that we have to connect the box with USB3. But in the flash process I get the errore Download IDB Fail. Anyone had this?
I know it's an old post, I successfully upgraded my emish x700 who had power on issues, now I see two types of memory partitions, phone about 1GB and internal_sd about 6GB. Why? Before upgrade I remember I had only one memory (think so) and I didn't have full memory issues when installing new apps. Who can help me?

D6603 Downgrade red light

hello my cell was in mashmallow , but ive wifi issues and get back to Lollipop, after this , the phone show battery low and dont boot or enter flashmode , only red led on plug usb or charge, anyone helps me?
UP - Anyone can helps me ?
Please only use your own thread instead of posting "Up" in a thread from 2015 and commenting in another one for the same reason.
As you may have noticed it seems to be a quite rare problem. If you can't turn it on and the pc doesn't recognize it in any way,
there's probably just one final step to try and that's Sony Repair Service (if they even try to fix a device that old).
But first make sure you got the right drivers installed as the device isn't gonna be recognized by the pc if they aren't installed correctly.
