Hi fellas,
I'm trying to flash my mt6573 device because of some mistake i made and my phone is now in a bootloop. I am using Sp flash tool but it gives me the [BROM] Can not pass bootrom start command via usb cable. Does this mean i have to use another cable like serial to usb?. I have attached a screenshot so you can see the details
Thanks

I've seen nothing on the 1050F or any of the Android based tablets (even numbers). The Russian forum has a guide for the Windows tablets (odd numbers). I'm trying to keep up on what they are doing. I'm collecting files to help us later on...
I'm proud to have contributed to this tip section .
Note that this trip works on majority of 5.0x devices.
One question : is there a 830f version with windows, as suggests :
http://shop.lenovo.com/fr/fr/yoga-tablet-2/
It's in french but selecting 8" let me thinl there's a windows 8 version
I'd ne happy to give it a try... after having succesfully rooted my 830, as i'm stuck with the E: error

When downgrading from 5.0 to 4.4 but fails to enter into the UEFI interface, how to return from UEFI interface to the Android interface.
1, if the BIOS settings have changed, please return all changes, so you need to write down what options were changed.
2, long press the power button to shut down, press and hold the volume + and volume - and power on, enter the FastBoot mode, using data cable connection computer.
3, extract droidboot.img and bootx64 from 5.0 OTA update package, this forum post has given the web link of the firmware, please download it.
4, create a folder named “flash” in the desktop, and then put the extract bootx64 and droidboot.img into the folder, and then create a text document, input “CMD” in the text document and then save, Modify text file txt suffix for bat. Turn off all the useless software!
5, open the new text document.bat, then there will be CMD interface, input
fastboot flash osloader bootx64.efi
and then input
fastboot boot droidboot.img
6, Then the tablet into the driodboot interface, and then in accordance with the downgrade tutorial directly degraded. Be sure to remember to delete a little something in the flash-LtoKK-PVT-810.xml:
Code:
<command>
<string>fastboot erase data</string>
<timeout>120000</timeout>
<retry>2</retry>
<description>Erasing 'data' image.</description>
<mandatory>1</mandatory>

<string>fastboot format data</string>
<timeout>120000</timeout>
<retry>2</retry>
<description>Formating 'data' image.</description>
<mandatory>1</mandatory>
</command>
, and then flash flash-LtoKK-PVT-810.xml use flash-LtoKK-PVT-810.xml,
7, when flashed (flash-LtoKK-PVT-810.xml), you will find that the tablet restart card in the logo interface, neglect it and forced shutdown, then press the volume+ and volume- and power to reenter the fastboot mode,
8, and then flash flash.xml, you will return to 4.4.
Thanks Tang1331726 for this detailled tutorial !!
I'm downloading the 1.15GB file over a poor wifi link... but as I understand you are proposing me to downgrade to kitkat.
As I've never rooted my 830F before when in 4.X nor mdified the bios of it, and updated only thru OTA to 5.01 last week, I'm a little confused about what you propose me.
I should use the proposed rooting technique for 5.0

To be clear. This is to fix the bios error when you upgrade to Lollipop and try to downgrade to KitKat? Also this worked on your 830F?
What's the fuss?!

This. I had rooted kitkat on a pal's 830LC. He update to an OTA (lollipop according to him) and got stuck in vicious boot loop. I downloaded YT2-830LC_S0184_150422_ROW and whatever I'd do, flashing system image would fail. Finally, changed force sparcing to 500MB, and suddenly, it's what's all the fuss?!? By the way, Windows 10 x64, used IntelAndroidDrvSetup1.9.0.
Thanks a ton :good:

Thanks Workdowg, and Thanks tang1331726 for your patience.
My english might be incorrect, but as I per my understanding this fix is when you are stuck and only solution is downgrading from KK to LL.
My situation is somewhat different as I've succesfully ugraded, without any glitch, thanks to the timming Tip warnig (this is a gold one, I wonder how many RMA Lenovo will have to deal with !!)
My exact situation :
830-F
Lollipop OTA succesfully installed (5.01 July 10 2015)
Problem occur using SuperSU (2,40, 2,46, 2,49) after successfully booted tethered recovery.
Can you confirm me that I've to do the process described by tang1331726 to fix the E: signature error, and that I'll still be under Lollipop ?
ps: I guess there's noway to get Windows 8 or 10 on my 830F, altough 851F seems very, not to say tottally, hardawre similar.

You are very welcome!
As far as the "E: signature error" please try posting in the Intel tethered recovery thread. Those guys should be able to help. Some people had luck by placing the SuperSU zip on the MicroSD and installing from there. Also try using the another recovery. I use TWRP on my 1050F.
We are trying to get Windows and/or Linux running on these Android based YT2's. Keep looking back here for more info...
So i rooted my Yoga tab just a few hours ago and it went great. Booted back in and installed some apps and started to remove some apps. I rebooted the tablet shortly after and got stuck in some bootloop at the title screen. (Lenovo for those who do) It boots three times and then its just black with some flickering.
I got in to recovery and did (probably really, really stupid) a reset of data and cache. figure that will solve everything. It didn't. But it did not however make it works. Still the same bootloop.
if i leave it on for like 10 minutes, the screen where you choose language and time comes up but i can't press anything. Then everything goes black and flickers.
I was on stock kitkat when this happened and I've searched all around the internet for answers. I don't understand half of the things a read. Reflashing a new bios and fastboot what not. Almost every link in every thread is dead.
I need help and i hope you can help me with a solution too how i can get my tab up and running.
I have no back ups what so ever because i'm stupid so i need just hard reset everything not worrying about saving anything. (didnt have anything on the tab anyways)

Hello !
You should try to flash stock KitKat Lenovo Firmware with IntelFlashTool !
Also, you should install some intel drivers : Intel® USB Driver for Android* Devices & iSocUSB-Driver-Setup .
KitKat Firmware must be available under Lenovo site !
Put your device in DNX mode ( press & keep at the same time all three hardware buttons , when device reboot just release power button ... you will see soon "Fastboot starting..." , right now you can release volume up & down ) - connect your device via USB with your desktop and start Intel Flash Tools . Just unpack stock KitKat Lenovo Firmware and select under Intel Flash Tools , Flash file : "flash.xml" from Lenovo Firmware !
Good luck !

Thanks for your help.
Unfortunately, i think it made i made it worse
The flash stopped at 70% and now i'm stuck in a bootloop at the first power up screen.
Can you still get in to fast boot,and are you sure you were on KitKat rom.
try and start your tab in normal fastboot mode (from the recovery console select 'reboot to bootloader' or use from power off the combo keys Pwr & Vol+ or Pwr & vol- one of these two should bring you to the Fastboot/Droidboot menu) and from there tell me what the ifwi entry says... BLADE_21....
Problem solved!
I had to check "Force fastboot sparsing" and change it to 500MB in FlashTool and then it worked. Everything is now up and running.
Thanks for your replies.

Bios Downgrade Tool Query
Hi mate, sorry for such a late reply but I'm struggling trying to get the bios downgrade tool to work on my tablet. Its plugged in and the "fast boot starting" message is showing but when I click on the tool on my pc and start it, nothing changes with the tablet. Is there an obvious step I am missing? Kind of new to this.
Thanks
Hello chaps. Random question. I have searched and searched for an answer but cant find a 100% reliable one. Can our 1050F 10.1 inch run Ethernet on the OTG? I have been liaising with Lenovo tech support via email for 5 weeks now and they are certain it can but I cant get it going with my Plugable OTG/Ethernet adaptor. So, what say you folks? Thanks.
On the Lollipop.

I have this Lenovo A328 which suddenly had multiple and continuous gapps crashes. I tried to do a factory reset but the problem still existed. I decided to flash the stock rom using SP Flash Tool. Flashing the stock rom succeeded but then after, the device does not charge nor boot up. It does not even respond to vol up(or down) + power which brings up a menu for testing the device(not recovery). I tried to format it first before flashing but the result is still the same. I also tried flashing stock rom from different source. Any idea on this one?
Update
I tried to flash a stock rom on my Lenovo A328 with SP Flash Tool but the process was interrupted and now after I flashed the stock rom successfully, the phone won't charge nor boot, not even to recovery. I noticed in my EMMC Flash that the sizes of GP1 - 4 are all 0x0.
I found a solution in here,
http://forum.xda-developers.com/show....php?t=2792667
It says that I have to flash the rom using DOWNLOAD first and then flash it again with FIRMWARE UPGRADE. I'm already at the FIWMWARE UPGRADE process but I got this error
Failed to get PMT info.

Hi, I am having the same problem. Could you help?
Hello everyone!
I am facing the same problem!!!
Tried almost all the solutions suggested on different sites or forums, nothing works, still no charge and no start...
Change the PC, the USB cables, drivers, ROM's, you name it... Someone said this MTK devices are hard to brick but still, why we cannot revive our devices??? Hardware failure? Not really according to some technicians as long your phone is detected by the pc in device manager, the phone CAN be "unbricked".
SO, we are missing something, we doing something wrong???
We need help.... SOMEONE???
please send me the firmware
I have the same problem about my lenovo a328. After flashing, it's not booting and turning on. It's not even charging. So what I did is I tried to firmware upgrade it and I got this ''failed to get PMT info'' alert. Someone know how to revive this phone?
I got 2 phones and they've bricked themselves
Hi,
I got 2 Lenovo A328s and they've bricked themselves, having the same symptoms.
I can get them to boot in Recovery, and I am waiting to download an image to sideload with ADB, which seems to work.
One of them was still in use, but had software glitches, like the camera driver not working in any app.
The other one was replaced 10 months ago, but after long time, it also bricked.
I haven't attempted any flash of new firmware.
I have the same problem, the phone isn't charging and I can't use vol up+ power buttons.
Can you send me the software please and some instructions?
Flashing Stock ROM failed.
Now won't boot of course, nor I can access fastboot. It's gone.
After turning Tablet on shows: "Boot Failed. EFI Hard drive"
and straight after that: "Boot Succeeded - Enter Setup"
Then BIOS like or actually BIOS shows - Title - VALLEYVIEW CO PLATFORM...
How can I fix fastboot? Or Droid Boot? I didn't even know I had BIOS in background?
I guess all blame me because I had Rooted... Is it trashing Tablet next step? Cause I couldn't find anything. I just wanted to go back to Stock ROM.
Anyone saw somewhere how to bring back fastboot? Or make it boot-able anything useful?
In that BIOS there is Boot Manager option and offers
- EFI Hard drive - Device path : PciRoot (0x0) /Pci (0x17, 0x0) /Ctrl (0x0)
- EFI Internal Shell - Device path : MemoryPapped (0xB,0xFFF50000,0xFFF8FFFF) /FvFile(C...
Can I somehow go somewhere from here?
Device Manager
Boot Maintenance Manage - has option Boot From FIle
- Boot Next Value... I'm lost.
I'm browsing that bios all possible ways to find something useful, but with no success.. Please help.
EDIT1: I find out that holding Power button and BOTH volume keys will start FastBoot - But mine stucks on "FastBoot Starting..."
There is already thread on xda discussing what to do when you got UEFI screen. restore-kitkat-bios-830-1050-v2 tool is the answer.
I lost that thread, so I'll answer to mine thread:
My state was - tablet ended up in UEFI. Couldn't get through but I did on the end with novice mistakes. So, here is advice and mistakes which cost me some time.
Spot that you need to be in DnX mode - kk-tool says that - pressed Volume keys and power button. Then tablet says FastBoot Starting...
Do not run KK bios restore tool with Intel Phone Flash Tool opened. Close Intel Phone Flash Tool. Then run kk-tool and follow instructions.
Then use Intel Platform Flash Tool to flash ROM (you need android driver and USB driver). I have used and working (not first image but some other second download worked): YT2-1050F_S0198_150422_ROW. Then I have tried to update to Android Lollipop but install failure.. Killed KitKat.. I'll google more tomorrow.
Let me know if you find working ROM able to update all the way successfully to Lollipop.
Looks scary when you see grey-blue UEFI screen - Oh, I must screwed up pretty bad if I lost FastBoot... You might think something like that, like I did. But kk tool really kick-off and helped.
I have searched quite thoroughly in this forum but I can not seem to find the restore-kitkat-bios-830-1050-v2 tool . I have this same problem and can not get my 830LC running.
