[Q] Is my Lenovo A850+ bricked? If not how can I fix it? - General Questions and Answers

Hello all.
I just received my Lenovo A850+ today that I bought from China (via ebay). After charging it to full I put in my o2 Sim and blank micro-SD card and started having a play with the phone. (It worked fine before I started messing). Noticing there was no google play store I set about finding a way to put it on. The first thing (perhaps wrongly) i did was install some lenovo usb drivers that some site told me to use with the idea I would flash a custom rom (which i never did in the end) and enabled usb debugging.
I tried to root the phone with a program called Xroot, which unsuccessfully rooted the phone, then I downloaded a new version which updated to Xroot 1.7.7 and that supposedly successfully rooted the phone. It also installed a new app with a name similar to xroot which i then opened. It has what looked like an app manager so i started deleting apps that i thought were unnecessary (bloatware). Suddenly the list of apps changed and the phone froze. I took out the battery and attempted to restart the phone. I now have the following problem:
After hitting the power button the phone it vibrates once, plays an animation and then gets stuck on the logo screen:
Left like this it occasionally vibrates once every 20secs or so but doesnt load any further. When plugged into my PC via usb, after a minute or so my pc recognises the device (but not removable storage and CD Drive (D Lenovo Suite (an exe) pops up. after installing a chinese software suite is installed, which does pop up when my phone is plugged in.
The phone only responds when i hold the power button, which turns it off. Basically I want to fix my phone, hopefully without sending it back to china. I assumed I could just get into a recovery menu and factory reset it. I dont think I can. I can get into the following 3 menus:
factory mode: (power+volumeUp) I dont read chinese, the top few seem to be info/component checks, the bottom one restarts the phone and the eMMC option doesn't fix anything.
recovery mode: (power+volumeUp+volumeDown)Has a menu with power off, reboot, wipe user data (didnt fix anything) and install update package (i tried copying an official rom onto root of sd card but it doesnt recognise it (it looks like it specifically wants a zip called update.zip) i even renamed but didnt help.
meta mode: (power+volumeDown) Doesn't appear to do anything and has no options.
Does any1 have suggestions on how I can perform a factory reset/install a rom or fix my phone or is it just bricked? If you want me to try anything just post and I will give it a go.
Thankyou.

you can go download a rom from needrom dot com.
there two roms there.
the official older is multilaguage and the newer is english/chinese.
sorry, but cannot post a link.

You need:
1. Flash tool
2. ROM (official or custom)
see instructions here: www*needrom*com/mobile/lenovo-a850/

thanks fixed now

You need to install the ADB drivers and the Drivers for your device. If they are both installed you can check if your device is recognised by PC by typing this command: "adb devices". If you don't know how to use ADB I posted a helpful tool.
Then you need to download a ROM on your PC and then flash it via Sideload to your device.

Possible bricked A850+
Have a possible bricked A850+ I tried to install custom recovery as I wanted a custom rom and it wanted SuperSU we installed but it failed to update binary 3 times on normal, when turned I it off and back on again it was stucked in the boot screen.:crying:
I have tried to wipe all date via Recovery which I can access but still no luck with the ordinary boot, when trying to use flash tool absolutely nothing happens when the phone is connected, so can anybody in here help with my problem?
Thanks in advance

Im trying to fix my GFs phone its stuck on the boot screen when the phone got turned off during an update
I got ADB installed and can see it in the CMD but its not showing my phone as connected,
I suspect this is because I dont have USB debugging enabled but seems the phone cant turn on i cant enable it, ive spent a few hours googling and googling but i cant find any way to get anything to work seems it wont connect to the phone
The phone does show up on my drives list when plugged in but it does not show up as an android device in the device manager. Am i screwed or is there another way to fix this?
Every single thing i try has "Make sure USB Debugging is enabled." ......
is there some way to enable it when i cant get the phone turned on....

Mega brick
Hi all,

stuck during boot, do not know what to do

hi all...
...I hope that you can help. Some years ago, I have flashed my polaris from o2. i then got myself an iphone and some new computers (using vista now instead of xp), so that I do not have any of the old files that I used back then to flash the phone. my father was using the xda for quite a while now. however, suddenly the device is not working any more: if you turn it on, the boot screen will appear, but then it is stuck and nothing is happening (even no rom info in the lower right corner). also a hard reset doesn't help to overcome this problem.
what I am trying now is to flash it, because I guess (and hope) that this might help. But, to be honest, I completely forgot how this works. I downloaded an original rom from this website today, but I cannot flash it to the device (stuck at 0%, getting an communication problem error). If I turn on the phone with camera button pressed down, the tricolor-screen appears reading POLA200, SPL-3.13.0000, CPLD-2. what am I doing wrong? your help is greatly appreciated.
Try flashing the rom from the tricolour-screen just make sure at the bottom of the tricolour-screen it say's usb not serial.
You will only be able to flash official roms as you don't have a stock spl not hard-spl.
thanks. I tried this one from this forum: RUU_Polaris_o2_GER_1.24.207.2_withSplash_noRadio_schaggo_[fixed]
but it did not work.
however, I now downloaded the rom from the original o2-site and it is at the moment in the process of flashing it - let's cross fingers.
damn, it did not work. I mean, the flashing succeeded, but the problem still persists: if I start the device, the start-screen appears, but that's it - nothing happens afterwards, and after some seconds, the device turns itself off again.
what could that be?
Could be the battery if the device turns itself off,try booting with the charger or usb still in.Or flash hard spl and try a different rom.
hi all friends if you are stuck on 0% and u cant install spl then do this ,,,
You can try this:
1. Stop ActiveSync
2. Open Task Manager (press Ctrl + Alt + Delete) on your PC and
stop these two processes rapimgr.exe and wcescomm.exe
3. Plug in your device via USB. Your computer should be asking install a driver. Install and continue.
4. Now Run mtty and choose USB in 'PORT'
4. type "set 16 0" without the quotes to tell bootloader to boot the OS after reset.
5. type "task 8" to get your device formatted.
6. Now unplug your device and manually reset it.
i hope you will be happy after .. thanks

[Q] A CHallenge for Developers (partial brick) Please Help

[SOLVED]
MESSAGE TO DEVELOPERS/ANYONE WHO CAN HELP
Long story short, i edited my build.prop incorrectly and reset (yes i know very stupid) now my motorola cliq opens up to the motoblur screen but repeated messages saying "Sorry! the process X has shut down" show up.
Literaly, nearly nothing can open up but i am able to enter usb mode if i fight with the endless popups. i can also enter recovery mode because my phone was rooted before this. The problem is that my recovery image doesnt have any options that could help me
(reboot, apply sd card:update.zip, and wipe data/factory reset)
i've tried putting an official motorola update.zip onto my sd card then running the apply.. but like i told you before my build.prop is messed up a little so an error shows up saying:
Installing update...
E/:Failure at line 1: assert file_contains("SYSTEM:build.prop", "ro.build.fingerprint=motorola/morrison_two_us/morrison/morrison:1.5/CUPCAKE/1.4.8:user/rel-keys" == "true" || file_contains("SYSTEM:build.prop", "ro.build.prop", "ro.build.fingerprint=MOTO/morrison_two_us/moInstallation aborted
Press Menu+Back to reboot
All i need to do is fix the line of code i messed up but i cant reach my systems files,...i attached my original build.prop and a copy of my corrupted one to show you.. I also cannot use the phone service or network service (even wifi) because like i said, nearly ALL the services are unable to stay on, they immediately shut off at startup.
Ways to fix this would be to REACH/EDIT THE SYSTEMS FILES
1. I cant use an app like root explorer since i cant access any apps on my phone even things like my settings
2. Turn on usb debugging somehow (I cant access my settings app so im lost on this one)
1. ingenious DESKTOP program that can somehow access my phone's system files without adb (if it can access the sd there has to be a way..)
3. Ive looked around to maybe find a custom image recovery that had options like editing system files (shouldn't be hard to make..) but ive found none with that option and im not sure how i would install it without adb...
What i CAN do
1. ENTER USB MODE (that has to count for something so Developers Please help me)
2. I can play with the motoblur intro screen to some degree to make it go away, then a blank black home menu appears. If i wait a while for the popups to stop at the motoblur screen, i follow the instructions but it gets stuck at registering a new account or existing one since you need network access.
3. ENTER REVOVERY MODE (but the only option that looks helpful is the sdcard update which gave me an error...) I havent tried the wipe data/factory reset because the factory reset doesnt touch the build.prop so its pointless
WHat should I do? WHoever sees this please give me advice or direct me somewhere to get it... THANK YOU
[EDIT]
BTW what i was trying to do on the build.prop was replace this line (ro.build.fingerprint=generic/sdk/generic:3.2/HTJ85B/140714:eng/test-keys)
with (ro.build.fingerprint=verizon/voles/sholes/sholes:2.1-update1/ESE81/29593:user/release-keys)
but i messd up and put
(ro.build.fingerprint=verizon/voles/sholes/sholes:2.1-update1/ESE81/29593:user/rel)
youll see this in the attachments...what this does is unlock my 1.5 firmware market to ALL the apps (updating to the official 2.1 using recovery wouldve handled this but i didnt even know of this update till after my mistake)
I just thought id mention...
if you have adb abilities you can push the old build.prop. If you do not know a out this then post back and I will help you.You said you can enter recovery, but that is stock original recovery that anyone can get access to. If you ever bootstrapped your phone you can try pull the battery out, wait about 10 seconds, then plug your phone charger in without the battery in. If your bootstrappped this will pull you into a more advanced recovery mode. The last option is to use rsd lite to flash an sbf to your phone if nothing else works. If you have never done this just look up sbfing motor cliq to stock.
Good luck, and remember to thank me if this helped
SOLVED!!
I fixed my phone on my own but THANKS to rootfan for being the first to answer.
HERES HOW:
I was able to access recovery mode and from there i discovered the sd update option.
It took hours of research and work but i learned alot about adb,motorola, cliq, etc.
Anyway, i originally found the Blur_Version.2.1.5.MB200.T-Mobile.en.US.zip and i tried to put that in my sd card (i could get into it from the phone) but when i tried to update using recovery it gave me an error so i decided to try the "latest 1.5 with Blur 1.6.1" which was actually very hard to find... you can get it here
motorola. com/staticfiles/Support/Experiences/sdcards/US-EN/tmo/cliq/downgrade-to-cupcake .html
Lastly, i put that on my sd as update.zip, went into recover, and the update was SUCCESSFUL! MY PHONE REBOOTED AND NOW IS ACTING NORMAL AGAIN. Now, im trying to update to the Androidâ„¢ 2.1 (Eclair):
motorola. com/staticfiles/Support/Experiences/sdcards/US-EN/tmo/cliq/2-1_index. html
but im still getting that error whether i update using recovery or the settings/about phone/system update option... Thats strange but my phone is still working normally and ill find a way to update to 2.1...
ONCE AGAIN THANKS TO ROOTFAN AND HOPEFULLY THIS POST WILL WORK FOR SOMEONE ELSE WHO MAY BE HALF-BRICKED (no adb, no usb debug, no root explorer) THERS STILL HOPE IN RECOVERY+USB DRIVE+BLUR VERSION SOFTWARES
Thanks man, now this is probabaly a redicilous reply, since im sure you would have already tried this, but you can try going into settings, about phone, and click on update and see if the 2.1 eclair ota update will work on your phone.

lg mytouch c800 bricked?

hi im pretty new here a friend of mine gave me her lg c800 mytouch to try and fix it for her.. not sure what she did she said she rooted the phone and the root was successful but i have a good idea that she doesnt know what she was doing..i will post a pic of the error screen im getting. but it says
E:Cant find misc
E:cant find misc
Finding update package...
E:unknown volume for path [sd:/download/adb_fastboot_and_other_tools.Zip]
E:Cant mount SDCARD:/download/adb_fastboot_and_other_tools.zip
Installation aborted
facory reset failed
restart factory reset..
now im far from a pro at this i know a lil more about computers and Ios devices..but ive rooted a few phones and to me it looks like she unzipped adb fastboot on her phone from her sd card??
ive tried holding F..A..vol down..and power..Nothing..
ive tried volume up .volume down and power still nothing..
BUT if i hold E..vol UP and power it brings me to a white screen that says S/W update
the big problem is the phone wont stay on long enough to do anything on the computer it stays on 3 sec. then reboots to same screen (computer says phone is unplugged) then phone just keeps restarting.
but the phone WILL stay on when i put it on the S/W update screen..but computer wont recognize the phone at all on that screen
ive tried the adb and fastboot commands but the phone wont stay recognized..it will recognize the phone and say thats its in recovery mode but when phone restarts it dont see phone no more..
well thanks ahead of time if anyone has any input or solution
and hopefully all this will make sense to someone lol
i think this pic will work.. if not ill try again
any ideas please?? or am i completely out of luck?

...do you mean that you can successfully communicate with the phone over USB, but you only have 3 seconds? What way is the phone recognized? Is it visible to adb/fastboot?

Yes In Adb device list it shows the phone and then says recovery..but after that I don't have enough time to type any other commands ..the phone is also recognized in "my computer" as removable device then when the phone restarts seconds later it says device unplugged ..and just keeps restarting on its own till I remove the battery...I just read on the forum in a post that Adb will recognize the phone if it's off but I remove the battery and put it back in and plug in USB and phone turns on and keeps restarting won't even let me turn it off!! I'm losing patience with this thing lol
But I don't get why the error mentions fastboot? Not my phone so if it's not fixable I don't really care but I'm just the stuborn type when it comes to fixing electronics ..again thanks ahead of time to anyone that helps cuz I'm completely lost on this one
Have you tried timing it to send a quick "adb reboot recovery"? If you can use fastboot, you can tell it to boot off a new, custom recovery img, without actually flashing it.
i have the same problem

i used an app on the market to remove bloatware. i removed slacker and the app stated that after two reboots that everything would be fine and the app would be gone. after one reboot the phone has the same screen this gentlemans lady friend has. it looks like the app its looking for is no longer zip aligned properly. someone told me to rename a recovery image the error message to trick the bootloader into thinking the missing app is there. hes an app dev so i figured he knows whats what. ive tried everything the gentleman in this post said and more. hell i have two of these phones and rooted the other and made a backup of that phone and dragged the backup to an sd card and rebooted to see if any of the backed up system apks would trigger a successful reboot but to no avail. i have all the drivers i need and adb commands but nothing works because the phone doesnt stay connected to my pc long enough for anything. please reply with some knowledge. ive been scouring the web for at least a month. i was so happy when i came across this. i actually became a member just to post about this erroer (look up diabolus ae in the forum search field. my post is about 3 days old with a better pic of the screen message. i bought a galaxy s II but i want to give the lg to my son. please help or respond:cyclops:

Normally, if you want to flash a custom recovery through fastboot, people will tell you to run 2 commands:
fastboot flash recovery nameofimagefile.img
fastboot reboot recovery
Since you don't have time to execute those 2 commands, you can tell it to just boot from the .img file, without flashing over your current recovery. (This is actually proper form, as you can test if the .img file works properly without damaging your existing recovery.) The way you do that is to 1st copy a recovery .img file to the root of your SD card, then execute the following 1 command:
fastboot boot nameofimagefile.img
Since you only have ~3 seconds, type the command in, and wait for the right instant to hit enter on the keyboard. If the command is successfully sent to the phone, it will reboot into that .img.
See if that works for you. Good luck.

Root Status = ROOTED
I cannot boot into recovery mode (but when i try i get this, look in pic 2&3)
Tablet Type = HKC (NOT HTC) p776a
ANDROID Version I think (98% shure) is 4.1.1 beta JB
What happened = A few years ago 2013 i think a got this tablet then i learned about rooting, roms, and such so i spent the next year or two trying to root the tablet. I finally got it rooted with a chinese root program and all was well (i don't remember the name of the program) then there was a update for su and i pressed the twrp/cwm mode on accident (I think I was talking to someone at the time) and now it does what is shown in the image 1 it is on some boot loop. When I try to access the hboot menu it does what is shown in these images 2&3. Also my tablet has a MicroSD card slot and the battery can not be taken out. the regular bootloop picture is image file 1 that is what it looks like when it does its continuous bootloop and P.S. the tablet turns off and on automatically during the bootloop. To try and fix it i have let it do its bootloop for hours on end turn it on and off tried looking for a compatible rom (to no avail) and let the battery completely die that is about it.

Okay. Just a few more questions.
Does your tablet boot into recovery (picture 1) even if you try to boot normally? (fastboot maybe)
Can you boot into anything else other than recovery? (try different button combinations)
Does ADB recognise your tablet when it's in recovery mode? (if you don't know about this, just post your computer OS and if you have ADB/Fastboot drivers installed on your PC)
If the anwser the the first question is no:
Does ADB recognise the device while it's in the bootloop.

sorry, i forgot to clarify the hboot. it pops up the "words" or whatever then automatically reboots there is no way to select options or keep the device on so i cant use fastboot unless there is a way i dont know of. P.S. the tablet restarts automatically so it is on for like 25 maybe 30 seconds then shuts off then turns back on and repeats till the battery is dead. My thought originally to fix it was to get a rom put it on the sdcard and see if that works but the manufacture does not supply the rom for my model only the p771a. and the only physical buttons are the home, power, the pinhole reset button, the volume and such buttons are virtual on the screen when it is fully on. And picture 1 i dont fully know what that screen symbol is the hboot one is similar but not that but yes it does but to picture 1 nomadder what i do even if i try to get to hboot menu. Sorry if this is a "little" scattered having explaining it. If it would help i can make a video and rar it and upload it here.

And picture 1 i dont fully know what that screen symbol is the hboot one is similar but not that but yes it does but to picture 1 nomadder what i do even if i try to get to hboot menu. Sorry if this is a "little" scattered having explaining it. If it would help i can make a video and rar it and upload it here.

sorry, i forgot to clarify the hboot. it pops up the "words" or whatever then automatically reboots there is no way to select options or keep the device on so i cant use fastboot unless there is a way i dont know of.

1. Download fixcache.bat.zip on your computer. Extract cachefix.bat from the file.
2. Run it. It should say just "Waiting for device..."
3. Now reset your tablet with the reset button and QUICKLY plug it into the computer and wait a few minutes.
Now try to get to that text in picture 1 and tell me what happends.
Also post the text you see on the computer from the file I sent you.
Tell me if

Umm, you said there is a reset button on the tablet so pressing that would probably reset it.
The error you are getting is because adb is not installed on your PC. Use this simple adb installer to instal adb. When installing just press yes to everything. MAKE SURE THE PHONE IS PLUGGED IN THE COMPUTER WHILE INSTALLING AND THAT IT'S ON!
Now run the file again.
If you want you can add me on Skype: janekmuric

If you want to know what is happening:
You are in what's called a recovery bootloop. It's when you can't get out of the recovery. What is happening in this case is that Superuser app tried to install it's binaries via recovery. Because some people don't know how to install binaries manually, the app puts a file on the cache partition so the recovery automaticly installs the zip upon booting. Now, this would be good so you don't mess up your device, but the zip file it's trying to install is faulty so it just breaks the device.
My attept at fixing this is to delete the /cache/recovery folder so it doesn't just install the file, and instead boots into a working recovery.

30 seconds is more than enough. Especally with an automated script like the one I sent you.
The first thing we have to do to fix your tablet is to establish a working ADB connection. Use the ADB installer i sent you. And look up on how to install Google USB driver for ADB.

PLEASE HELP ME with galaxy S2 SHW-M250K Boot problem

Please guys, my galaxy S2 SHW-M20K (Korean) is in trouble.
I bought it from a 2nd hand shop , and it was runing Android 4.1.2 Jelly Bean (rooted stock rom). I had no problem with it till today when I tried to install "CWM Recovery", After searching the web i found a post with two files that supposedly could do the task. These files are:
1. CWM_KT_M250K.tar
2. Tegrak-Kernel-Build-39-for-SHW-M250K-UE18.tar
Using Odin, I triedd the first file but it couldn't work, and the phone could not boot so i downloaded the "rooted factory firmware" and flashed the phone. Everything was ok. Later I tried the second file. Again the phone could not boot and stuck at the logo with a yellow triangle. After waiting for about 5 minutes I tried to shut it down by pressing the power button it did'nt respond. (Now this is a point that I regret), I removed the battery as a way of forcing to turn it off.
Now my phone cannot boot. It doesn't respond to power button, neither does it allow me to enter recovery mode nor download mode. But When i connect to the charger or pc, it start charging and keeps cutting off the charging frequently. But it only allows me to enter download mode when connected to pc. When I tried to flash the "rooted factory firmware", again, the flashing goes smoothly but when the phone starts rebooting it fails as if there is a power cut. Is my battery damaged? Can someone give me a guide on how to fix it?
I need your help gus, I am not an expert in the rootings and roms,
Pardon My English. It's a foreign language to me.

As u mentioned, I think that your phone has gone to a Soft Brick. I don't know much about the Korean build, so Google it to solve the Soft Brick. Try flashing the stock rom via odin but I don't recommend it since it may cause your phone to be hard bricked if not done properly.
So go to the service centre, you'll get more help there

I thank you sir for responding to this. From what you have said, I think the best decision is to take it to Samsung service center. (For I have tried to google it but I couldn't get a solution). I would also like to know if it is repairable, and about the cost, is it worth repairing or should I think of buying a new phone?
I am stranded.
