[Q] Help. Lenovo S820 won't power on - Android Q&A, Help & Troubleshooting

Greetings there fellow xda members...
Yesterday a friend of mine gave me her Lenovo s820 (MT6589) to change her ROM.
It came rooted so I just downloaded from play store 'Mobileuncle MTK tools' and selected update recovery.
I flashed it and then rebooted. The recovery was in Chinese so I rebooted again and searched for an english copy of cwm.
I found a guide here about how to flash a custom ROM on this device and downloaded 'CWM_v6.0.3.4_S820_ROW' that was provided.
I flashed the .img file using mobileuncle but after I pressed reboot the phone wouldn't turn on. Not a boot loop, just nothing.
After a couple of hours searching and trying different solutions the phone powered on and I have no idea how I did it.
Now sometimes it boots, sometimes it doesn't.
Most of the times it boots it's after running memory test using the 'SP Flash Tool v5.1352.01' but I don't thing they are somehow related.
Also, Flash tool displays the following error in memory test "ERROR: NAND Flash was not detected!"
but I had no luck finding a solution for that either or if it is somehow related with the problem since most of the people facing that error had formatted NAND something I didn't.
Thanks for reading, I hope someone can help me fix it otherwise I'm in some serious trouble :fingers-crossed::fingers-crossed::fingers-crossed:

[Q] Allwinner clone. Soft bricked: black screen, reboot loop, recovery corrupted!

Hi I have an Allwinner A10 clone (Kurio 7), it is designed for kids but otherwise a standard android tablet.
After hours of googling I rooted and installed CWM & Gapps (not included in the stock ROM). So far so good.
The stock ROM was causing issues with some apps, it needed to go.
I flashed CM10 and it worked but no touch screen. It needed a compatibility flash to make it work. You can guess what's coming. I picked the wrong one and now the device does the following:
Reboot loop
Black screen (backlight though)
PWR+Vol up no longer gets to recovery
Vibrates constantly between reboots (due to wrong patch I'm guessing)
ADB picks up the device for a split second between reboots but "adb reboot recovery" does nothing. Even when using wait command.
Tried "fastboot flash recovery cwm.img" after wait command, no luck.
Is there anything else I can try?
I fixed this.
I used the GoClever TAB A73 ROM and instructions in their support/update/download area.
Sorry I cannot post links as I am still a newbie.
Anyway flashing using Livesuit this fixed the problem.

Hi, can you please share with me how you manage to unbrick your Kurio 7. I had just bricked mine trying to install CM10.
Thanks.

I guess this is the site he is refering to:
http://www.goclever.com/uk/support,c3/software-update,a28.html?aic=5&aia=185&ail=10
The LiveSuit pack is there for download, as well as the roms.
But there are three different 4.0 roms to choose from, and also a couple of 2.3 roms. I dont know which one he did use.
Since your Kurio 7 is bricked anyway, I guess you can try one by one and see if any of them work.
Please tell which one, if you succeed.

[BRICKED] Need help!! Alcatel One Touch S'Pop (4030x)

Hi guys, new to the forum, but been reading for a while now.
I need some help with my gf's device which i got messed.. So here is the problem:
Device: Alcatel One Touch S'Pop (4030x)
Carrier: Globul(Bulgarian)
Root: YES
SU Status: Installed SuperSU
Stock firmware: latest ver of Android JB 4030x modded for globul
Recovery: Selfmade CWM.
So the problem is that the device was stock and sim locked by carrier globul, what i was trying to do is root inastall cust recovery and install new rom, hoping that this will debloat the device and eventualy sim unlock it, now i am stuck with a white screen every time i try to boot it, juat after the first boot animation. Tried to go to recovery - work flawlessly. Tried re-installing the custom ROM several times with no luck.. Here is what i done:
Rooted with VRoot, then installed CWM recovery via MTK Droid Root & Tools, all worked fine, the stock (rooted) ROM booted with no problems at all (restarted couple o times)
Then i downloaded to my SD the last version of GE-Rom from MXDevelopers blog and tried to flash it via recovery, following their guide(only difference that i used CWM instead of TWRP) everything went well and nice, then i pressed "Reboot device now" option in the recovery and it rebooted, shown the 1st bootlogo and than that white screen (ofdeath) and it doesn't do anything except when i press volume down and hold it, it vibrates as when you switch silent mode on with the vol keys, also i noticed that the power button works as supposed (locks unlocks).
What i need to do is getting a custom rom working on the device, or at least a stock (non globul) rom working on it..
I tried to flash thru recovery the X9 ROM in hope it will do the job but null... I tried several times to install and re install the rom with no succes so far. What i am thinking is that i somehow damaged the boot image ( i havent touched it but i dont know if the custom rom had tried to modify it. )
Please help!!
Will click the thanks button, i promise

[Q] Star n800+ after rom flash shows only white screen

Hello guys, i need little help with my phone, so here is what happened: Two days ago i tried to turn on my phone, it started booting but the cycle repeated again and again so I got in recovery and wiped data/catche, but that didn`t helped. I thought that if i change the rom maybe I can fix the problem so I downloaded my rom from needrom (there were 2 roms for my device) and started flashing with Flash tool. I downloaded the first rom to my phone and tried to turn the phone on but nothing happened.. I downloaded the second rom and it worked, the phone booted but the only think that I can see is blank white screen, the touch is working and the buttons, when i click somewhere i feel the device vibrating but thats it. One time i managed to make the device appear in my computer as a normal android phone, dont know how this happened. So can someone help me please, if you have a phone like mine can you backup your rom and send it to me or help me find a working one, or some idea how to fix the blank screen. Thanks in advance

[Q] Help Reflashing Doogee F1 Turbo

Hi I really need some help unbricking my phone.
I have a doogee Mini F1 Turbo which was rooted. Today I did an OTA update (bad idea).
During the update the word ERROR appeared on the screen. When the phone rebooted it was stuck on the white boot logo screen.
I've downloaded the SP Flash tool and rom from the doogee website
When I try and re-flash I get the Message "Error initializing scatter file failed. Please check the name of scatter file you load is legal"
Hopefully some body can point me in the right direction and help me get my phone working again.
Thanks for your time,
Gavin
Hi Gavin,
I'd you get a solution to this? I'm facing the same issue.

Hi Denclan,
Sorry about the delay inb replying.
Yes I found a solution to my reflashing problem. What I had to do was move the contents of the ROM Download into to same folder as the Flashing program. This then worked.
I would be carefull with the R07 update.
After reflashing my phone I updated it before rooting. Then rooted it. Everything seemed fine but the battery drain was shocking so I've flashed it back to R05 and that works a treat.
Hope this helps you out.
Gavin

Lenovo Tab3 (TB3-710I) bricked!

Yesterday, I flashed Tzul's S000031 ROM for the Lenovo Tab3 7 Essential (TB3-710I). It was a successful root, until after I started the tablet again, it only let out a long vibrate, with short vibrate intervals after about 5 seconds.
I first flashed TWRP on the tablet yet I think it did not load, as I started into recovery yet saw the Android Stock Recovery running.
I've been looking at guides, flashing other versions to no avail. SP Flash Tool always shows that it cannot load DRAM (4032 error or 0xFC0 error).
This happened for the first time that I've been flashing and rooting phones. I hope you help me out here.

Hi, did you find anything?
I have three TB3-710l (they are the company I work for), I have successfully root 2 of them but the newest tablet doesn't have the same luck.
First I install TWRP by Tzul, but the TWRP have an error never mount anything.
Second I try to flash stock firmware (Lenovo_Tab_3_TB3-710I_MT6580_S000032_160921) then the same happened, never turn on and just vibrates.
Always using SPFT, and now I have the same problem has you: always shows that it cannot load DRAM (4032 error or 0xFC0 error).
EDIT: Hi, for everyone who get in here with this problem, please read all this thread.
I unbrick my tablet with this answer in specific.
Good Luck!
