Hello, after playing with my z90 (with the original rom that was Z90a40_USR_S118 international, bought in october 2015) I wanted to clean it up and make some updates. So I made my backups etc... Entered the recovery (not the green lenovo one wich is very limited) with hold vol - , I choosed to wipe (the phone was encrypted just to mention) all that I can and reset to factory, all was done but when it finished, it reboot and it stuck to initializing just after lenovo logo it reboot... initializing... and it s an inifinite loop. So I retryed to go to the maintenance recovery but it s not possible a black screen come and it reboot, I can go to the limited lenovo green recovery, but no factory reset, so I make the wipe datas etc... nothing... infinite reboot loop!
So I found some rom put them in the micro SD, go for an update.zip with the recovery, update work well but... initializing.... reboot...
Grrr, lenovo... So I take the big tools, installed a minimal win7 with qualcom drivers, lenovo ones, qpst. I tried many manipulation to enter the download mode with port com (I finaly managed multiple times with not the exact manipulation it s vol- + power + 10s and multiple spanning of the vol - button....) And I have succefully flashed multiple roms with qfil but with always the same results... initializing, reboot... I don t know where to search now, I someone can help me to find where to go, perhaps reflashing the recovery or I saw the .qnc in a russian forum but I can t understand one word.... 2 days of flashing make me hate my lenovo, my first brick with a phone :( . Any help?

Thanks,
sorry for my bad english

Hi,

here is my solution if can help.

I had on my vibe shot s208 rooted ROW. It stacked after SU update in boot loop.
1. I did wipe data without formatting from recovery mode (Vol+ and Vol- and Power button. When Logo is on release power button and hold Vol+ and Vol - until you are in recovery mode). STILL boot loop.
2. I did wipe data with formatting from the same menu. - STILL boot loop.
3. I did factory reset from recovery menu (Vol - and Power after logo is on release Power and hold Vol - until you get recovery mode) - STILL boot loop.

Then I did next:

1. I downloaded and installed QFIL (QPST_2.7.422) - I am not allowed to post links yet.
2. I have connected OTG adapter to phone. Phone was off.
3. then connected OTG to PC. It was some HDD activities but I did not hear any sound.
4. press Vol- for as long as something is going on - HDD activities. Then I think came up sound too - but not sure.
5. I had installed Qualcomm USB drivers from before I suppose.
6. Because I couldn't see my device as ...908 I disconnected and connected again usb cable... then I got my device as ...908 in device manager, but it was written "RECONNECTED" or similar in front of word "QUALCOM".
7. Then just follow instructions for QFIL. and ROM will be installed.

First I have installed INTERNATIONAL no root ROM. But because I needed phone to be rooted in order to use data recovery software I flashed again with s240 ROOTED. When I flashed second time I did not use OTG, just direct usb cable connection to PC, and my phone was again recognized after I reconnected usb cable and in device manger was "RECONNECTED" in front of word "QUALCOM".

Hello, thanks for replying. But I already tried all the roms with qfil, they were successfully installed as wtih miflash but I always got a initializing boot loop... Unfortunately I tried some other method, I successfully erase all partitions, I m now in 9006 mode with a long vibration on start and I cant do anything now :) No flashing works anymore... I ll try some stuff when I had a little time.

did you find a solution ?? , cause I have the same problem :( ... tried everything, adb or cwm recovery won't work cause my device is not rooted nor the usb debugging is on .. so am stuck with this "initializing loop".. flashing didn't solve it for me, I tried every ROM I could find, rooted or not .. nothing .... this problem happened with my phone after wiping user data and trying to restore QCN, cause before this problem I had another one with network services, tried to solve it, and here I am, from bad to worse

I reinstalled the drivers QDLoader HS- USB Driver. I maintained volume + for 3 seconds , however, nothing happens ! (Before it worked ) I also tried adb reboot eld the prolème is the USBport phone is not known ! :(
I followed the procedure of DejXDA carefully until the end staying press the VOL- the phone starts to recharging battery ... have you others sollutions ? thanks in advance.

Hey there !
Same problem for me... The solution may be to rebuild the partition table, but we need a working phone, and a backup with QPST.
Would anyone post a *.qcn file from his phone, made with QPST Software Download ? or a *.hex ?
And the user partitions ? Or a factory image (*.mbn) ?

Any gurus here, what would you advise for that problem ? Would using QPST properly work ?

Cheers !

Z90-7 (Z90a40) unbricked (at last...)

Hello!
After days and days of fails, my Z90-7 is unbricked!
How?
Just follow the OTG cable method, but copy in the SD card, in the sdfuse folder, this image:
Z90a40_S209_150716_ROW.qsb
You can download it from russian forum*, freely.

*I'm not allowed to post links, but enter the exact reference (Z90a40_S209_150716_ROW.qsb) in Google search (don't accept the Google's proposition to correct it), the link is the first answer. Use Google trad as I did if you don't speak russian .
:)

Hello ,

I wanted to set an international Rom 5.1 and now since it gets stuck on initializing indefinitely.

I have access to the recovery mode so I spend not to turn off the phone.

I Agency will proceed as this I put out the létélphone I press the volume + and I connect it to the ordidateur to put in download mode, but there is nothing after it launches in initializing .

So I essyer with presses of flight - and connects to the PC and it remains on the Lenovo logo.

In prériphérique manager there wrote lenovo ADB android.
Can not have Qualcomm hs -usb in the Port . even after installing the driver.
