[Q] Is my Lenovo A850+ bricked? If not how can I fix it?

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/

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....

HTC DesIre 320 Bricked, no boot, only recovery...

Hello, I'm about to giving up,
Something happened to the phone and now it won't boot, it barely show the "ANDROID" logo when it restart itself. I can enter to the recovery menu, it doesn't have clockwork recovery nor twrp, just the basic recovery. So far I tried:
wipe data/factory - didn't work.
wipe cache partition - didn't work
apply update from adb: Adb just work with sideload and that's it, for everything else it shows closed. I tried sending the rom with sideload and it fails every time:
* failed to write data 'protocol fault (couldn't read status): Invalid argument' *
So I took my sdcard and copied the room there, so I tried
apply update from sdcard, it starts and in no time it says:
Installation aborted (APPLY_EXT).
I'm very frustrated right now, nothing works, it seems that the manufacturer did great effort on being the only one who can recover this phone, who appears to be from China, the MTK6582.
Fastboot? it doesn't show the device, it would be my last hope but no, since there is no adb, I cannot call fastboot, and the apply update from adb only work with sideload (yeah, f**k me).
The best course of action would be to throw it to the trash?
Thanks!

Hey, I'm in a similar position to you. However, I went about it with a slightly different route. The chip used in this phone is the MediaTek 6582 (I think?). I downloaded some tools from a thread on here that includes the 320 rom and the necessary software for flashing. I've flashed MediaTek devices before, the Huawei Ascend G610 and G700, both successfully. This one is giving me headaches, the damn device keeps disconnecting. HOWEVER, if you're lucky and you don't have the same problem with disconnecting hardware, you should be able to flash a new rom via the software. It'll take a while though. Also, I don't know what'll happen to your IMEI afterwards, so that's another possible headache (both the G610 and the G700 lost their IMEI info, but I'd taken steps to back them up beforehand so I could just restore them; here, there's no option to backup).
Here's the thread: http://forum.xda-developers.com/android/general/htc-mtk-cpu-flash-files-flashtool-t3114271
Let me know if you need help. I'm screwed in that the damn phone keeps disconnecting. Similar to you, no fastboot either. Plus, no RUU for this HTC. Hell, the internet barely knows this flipping phone.
Cheers, and good luck.

Ditto!!!
Hey guys I am having the exact same issue, luckily for me it is my Mrs who done her phone in and not mine . She has the HTC Desire 320, I believe she tried to root it on her own without even asking for advice, I think she used the app Kingo Root, she said she went to remove the root but when she uninstalled the app it didn't remove it. (LOL I told her well perhaps that's because there will be some way of removing it, aside from just uninstalling the app), anyway she proceeded not to care and carried on using her phone as normal for maybe a week or two at most, then about midnight one night, came down and said to me,
"my phone had an update and on restarting I just get a dead android, if you press the power button you get some options so I clicked erase"
Click to expand...
Click to collapse
I was like nice so basically you F***ed it!!!!, and for about 2 weeks now I have been endlessly reading post after post, forum after forum, trying rom after rom, RUU, all kinds of things.
Here is the situation, the phone will boot as far as the HTC logo, it will get stuck in a short loop and reset itself 4/5 times repeating the HTC logo, eventually it will end up at the dead android pic (the android on his back with the red exclaimation mark triangle) with the words 'no command'. From here I can press the power button once to get a list/menu of items (What I assume to be the recovery menu). I can backup data, I can restore the backed up data (both of which do nothing as I guess there is nothing really to back up), There is an option to restore from sd card (which I have tried numerous roms and to no avail have any been successful), I can erase the cache and I can also erase everything and recover, the erase side works fine, I did notice in each of these menu that if you press volume up to activate them and then press the power button once, then the writing dissapears and the android proceeds to have his moving atom type thing in his belly, saying 'erasing..', however even with them completed successfully, it still does not restore.
NOTE!!! If you choose the erase and restore method, once activated with volume up, press the power button to get the spinning atom and erasing... message, when this finishes the phone will reboot, it goes to the htc logo, resets itself, goes to the logo again and then just stays at a black screen (almost like a frozen state, I left it for quite some time and it never changed).
I should also note, which I didn't to begin with, but no matter how long I hold the volume down and power button, there is no such hboot/fast boot menu at all, if you hold the volume down and power button even after it displays the htc logo, the phone just proceeds to endlessly reset and loop through the same process forever.
The only thing I can seem to access with little success, is the ADB CMD prompt through the Android SDK,
Code:
adb devices
will indeed return the device (a set of numbers with the word sideload beside it)
Code:
adb usb
Apart from the odd fluke, this has seemed to fail everytime with either an error about a protocol or an error stating 'closed'
Code:
adb sideload "ROM_FILENAME.ZIP OR .IMG
Occasionally this will throw the protocol error, but generally succeeds and displays the 100% most of the time, however the phone doesn't even try, it just almost instantaniously returns the error message :
Code:
[B][I]Installation Aborted (APPLY_ADB_SIDELOAD)[/I][/B]
NOTE!!! That the android lays on his back with this error, but it only says error below not no command.
I am pretty sure that I already came across a solution very similar to the one you posted above, and I just couldn't get it to recognise the phone, the only way the RUU would work, was by completely removing the battery and plugging in the usb, however without the battery in the phone, it just constantly beeps via usb, so I guess it turns on, then off, then on, then off, forever!!! So the RUU fails everytime, if I leave the battery in and try, the RUU program does nothing whatsoever! So I am at a complete loss with it now.

Any luck with unbriking the HTC?

Maybe this is the solution, good luck.

I think that you no tell true because I tried this method with volume keys and nothing. Flash tool still show error. Its impossible to write android without battery. I think really put your phone to rubbish or sell as lcd+digitizer parts I think just we must waiting for new custom rom flashable via stock recovery. 320 is still new model and developers no moke any custom rom. So maybe only HTC service may help, only in HTC Factory peoples know how install android and bootloader on hard bricked device.

Acer Iconia One (B1-770) - How to reset to factory? (no recovery and forgot pin)

Hi All,
Doing a favour for a friend whose son keeps changing his pin on his tablet and has been changing it so often (to keep parents out no doubt) he has forgotten the pin and cannot get into the tablet.
His father doesn't really care to lose what's on the tablet as it's the kids own fault and has asked if I could restore it to factory.
In trying to do so i have encountered a litany of issues which i will describe below:
1. I have tried holding Volume Up + Power - This takes me to a screen that just says something to the effect of "Fastboot mode" and nothing else and it essentially just hangs there until batteries run out or I hit the reset pin.
2. I have tried flashing it over ADB using my laptop but also no luck as the device is "unauthorized" since I can't get in to the device with my laptop connected and hit the "authorize" button that comes up when you connect to an ADB interface.
This also means I cannot root the device and flash a recovery on to it.
3. They did not have a google account so restoring via the google account is also a no-go.
I'm not sure what other options there are but I find it very odd that there is no way to get around this. I do realize it's a form of security, but this is a legitimate scenario where one needs to flash the device and there is no way to do so. In any case, i know this is a hairy topic so just my .02, dont want to have a debate lol
Is there any way for me to reset this device to factory or at least flash some form of android os on this tablet?
Thanks to all who read and especially to those who assist!

Still no luck, any thoughts, anyone?

for the life of me I cannot put this device into recovery mode.... i've tried all combinations of buttons but at most it always goes into safemode.... i don't feel like there is recovery on this device even though that probably doesn't make sense.. i simply cannot get INTO revovery.
Has anyone been successful getting into recovery on this device model?

Have you tried on fastboot mode? fastboot -w

New Samsung Update for A51 is Bricking phones

Good evening folks. Over the Past week, for some reason, people who downloaded the new Samsung update for A51 have had their phones bricked. FOR SOME REASON, this seems to only be happening here in South Australia. I haven't seen anywhere reporting on this issue other than local news. I have had three A51 phones come into my IT store, all with the same problem.
here is a link to one article talking about it: https://7news.com.au/technology/sam...ng-priceless-photos-vital-contacts--c-9340963
Upon installing the update, their phone will restart then it will not progress past the SAMSUNG logo. I have been able to get each and every phone into recovery mode however I when I try and reboot the phones into bootloader, they simply say "entering fast boot" and then don't progress any further.
Since I have been unable to boot the phone to bootloader I don't have many solutions in front of me, I can either factory reset the phone which has been proven to work, or I can try some alternative method. Simply put, I refuse to take the simple way out and simply factory reset the phone, I don't want my customers to go through the trouble of losing their photos.
The only real option I see is using ADB to install either a new update or new firmware, however, I have had ALOT of trouble finding the necessary software. I have been able to get ADB to detect the devices with a USB connection, so I tried installing some firmware, I found for my device. I didn't trust that this was the correct software, but it couldn't hurt to see if it worked.
Using a515fxxu5gvk6, I was able to find a website where I could download Firmware https://samfw.com/firmware/SM-A515F/TEL I don't believe this to have the correct software but it was the only option I could find that didn't require money or an account.
upon extracting the zip file and typing ADB sideload <file name> it would start the process of installing the software however, it would only install for a single second and then stop working. I would be greeted with the messages: "footer is wrong", "update package took 0.3s", and "signature failed". I believe this means I have either grabbed the wrong software or I have tried installing the software wrong
I really don't know where to find the correct software, and I don't even know if I will be able to update the phone using ADB since I never was able to enable developer tools.
I have already spent quite a few hours on this, and it's starting to drive me insane. I have gone down so many rabbit holes researching different options only to come back up empty-handed. Im lost and really don't know where to turn.
any help would be literally amazing, if someone could even point me in the right direction that's all I need. even if you tell me there is nothing that can be done and I need to factory reset the phone I can at least go to sleep knowing I god damn tried.

Well, one thing you should know is that Samsung doesn't use fastboot to flash software like many other brands. It's unfortunate to say that a lot of the guides you read online are just copy-paste of guides that do use fastboot. Adb doesn't really flash software without elevated permissions afaik.
You can flash firmware using Odin for Samsung devices. There should be plenty of guides online on how to use it, your main goal right now is figuring out how to boot into download mode for Samsung.
What I would do is try to turn the phone off completely if you've been able to boot to recovery. After that, hold both the volume buttons and while you're holding them, connect your phone to a PC. This should force the phone to boot to download mode. Read the screen as it may ask you to press VOL + to proceed.
After that, you can flash the files
AP_XXXX
BL_XXXX
CP_XXXX
HOME_CSC_XXXX (Use HOME_CSC instead of CSC_ so that the phones don't lose any data)
And after that, you should be able to flash firmware

Thank you so much for your reply. I have spent the past few hours setting up Odin and installing the firmware.
I have run into another problem, I select all the firmware I wish to install then click start. It loads for two seconds then says "PASS!". However the phone is still stuck in a boot loop
I believe this is because I haven't turned in USB debugging, since I can't get into the phone I can't turn it on even if I want to.
Is there another option?

USB debugging isn't needed when flashing through Odin. You're most likely just missing the Samsung dev drivers. Try and installing them: https://developer.samsung.com/android-usb-driver

Question HELP PHONE STUCK ON BOOTLOOP AT GOOGLE WRITING AND CANT GET DATA OUT

Hi all,
Im in a desperate and urgent need of help.
My Mrs pixel 7 pro is stuck in a boot loop that restarts 5 seconds after the google writing appears when starting. I wasn't home when it happened but she doesnt really make sure her phone has some battery before turning it on, as soon as she sees 2% she starts it, so im guessing maybe she bricked it while the phone was trying to apply an update when turning it on as she said that the external battery didnt have any juice left inside.
Anyway,
I know i can wipe the phone from recovery mode and make it into a factory reset phone. The issue here is we have over 6000 photos and videos of our son in that phone that she hasnt copied to the external hard drive i gave her for months due to her not liking that her little laptop is slow.
I tried recovery mode Reboot, i tried going into safe mode (no luck as it will go straight into fastboot mode). She doesnt care about a lot of things and obviously she never unlocked the developer setting or bootloader so device state is also locked.
I am begging you, anything any info or advice on how i can get those pictures out of the phone. Is there any way i can flash the stock firmware just to make the phone start and copy them after?
Any possibility or chance or retrieval?
I am willing to pay anyone that can guide me in the right direction as there are over 6 months worth of photos and memories.
Thanks in advance and may the luck be on my side.

If you can enter recovery mode try to sideload the same exact ota package of the rom she's running, maybe that can help. Good luck!

As @acuicultor said;
Here's Googles official OTA updates and instructions etc.
From what i've read briefly and as far as i can gather (still running a stock pixel 7 pro - for the first phone in god knows how long, so i'm not well read on this device but...) if you can sideload the latest OTA update via sideload then you should in theory be able to save the data and boot again. But if you flash full firmware then your device will be wiped in the process (if that's even possible with a locked bootloader).
Very best of luck
EDIT: hmm thinking about it, you won't have enabled USB debugging in dev options, hang on, i'll reboot direct to recovery to see if i can get the device recognised without USB debugging enabled. Sorry to be vague (hopefully someone more experienced with this device will chime in with more advice), like i say, i'm not rooted, flashed with custom rom - nothing, just plain old stock so i've not read up much on proceedures for this device. Bare with me!!

Had another thought, do you or have you been using Google photos to view your images on the device. If so, did you enable backup photos online when you first set the app up? If so, they could be backed up automatically...
Edit: my bad..
Try this link
If that fails just Google 'Google photos sign in'

Just tried from recovery to run some adb cmd's, no joy without enabling debugging 1st
There may be hope... If your photos aren't backed online already from above link...
EDIT:
1. From power off state (make sure the device is charged before apply any ota update) Press vol down and power together. As soon as it boots to google logo, let go of vol down, then power. That will put you in fastboot mode where you use the vol up/down to navigate to Recovery mode and power button to select.
2. Then when you have the screen that says 'no command', press power button and CLICK vol up (releasing vol up straight away but keeping power pressed). That'll take you a blue menu at top of screen.
3. Use vol buttons to navigate to 'apply update from adb'. I have checked using 'adb devices' and 'adb reboot sideload' cmd's on PC and the device is now recognised...
Will write further instructions shortly. (no guarantees this will work tho without losing data...or even if it'll work at all - i suspect the OTA update with just fail to transfer)
OR there is another option, using the same instructions above (1) in fastboot mode use the volume buttons to navigate the menu, power button to select Rescue mode. Then contact your service center for support who will advise/offer support - hopefully, which may end up having to send the device in and still offers no guarantee of preserved data

Following the link it's all explained there:
- no USB-Debugging needed
- booting recovery by key combo
- no loss of any data when using the OTA files
Also turning on USB-Debugging in developer options is not necessary for the recovery. It's enabled by default and moreover the recovery doesn't consider any system settings like disabled/enabled USB-Debugging.
