[Q] Lenovo A830 Boot Loop No Recovery

I have a problem with one of my Lenovo A830 phones.
I bought it from Etotalk, so it came rooted, and with their custom version of the Lenovo Stock ROM and their custom version of CWM 5.5 installed.
I tried formatting my SD card and then doing a factory data reset from within the operating system. (I was intending to install MIUI V5 after rebooting into recovery).
However, on rebooting, the device is now caught in an infinite boot loop, and I am not able to boot into recovery mode (by holding down power and both volume keys). It loads the initial splash screen, then shows a few seconds of the Android character and some whirring cogs before rebooting.
I am able to boot into Factory mode (power and volume up) or Meta mode (power and volume down). Factory mode has a number of options, but they are all in Chinese characters, which I am unfortunately not able to read.
I did notice that my SD card seemed to be write protected when I tried to format it in my computer and to copy on the new ROM - I solved this by putting it in a different phone and reformatting it. I wonder whether the factory reset process has write protected something it shouldn't have?
Does anyone know how I might best proceed? I've been digging around on the forums, and tried a few things, but there's nothing which seems to provide a coherent solution for this problem.
I've got the latest Android SDK Tools, MTK Droid Tools 2.4.8, SP Flash Tool 3.1312, some additional ADB drivers (120827 v3.7) that I'm not sure how to install, the latest MIUI V5 ROM (3.8.16), and the latest stock Lenovo ROM (S118 from Need A ROM, just in case I need it).
Maybe different SP Flash Tools version?
I had trouble using SP Flash Tools v3.1312 with A830. Once I switched to v3.1304.0.119 I was able to flash both the original ROM and the custom MIUI one without serious issues. I'm unable to post the download link but google it.
One other thing is that when connecting the phone, it usually loads the something something Preloader driver, which is no good (even if it gives you Download OK). When attempting to flash either ROM, try pressing both the power and volume up buttons while connecting the phone (after pressing Download), only way it worked for me.
Good luck!
I managed to sort this out quite simply in the end!
On the Lenovo A830 (and presumably other Lenovo Android phones?), you enter recovery by pressing power and then pressing volume up / down together after a short pause. The short 1 - 2 second pause is important, because if you try and press them at the same time or in quick succession it doesn't seem to work.
I then installed MIUI V5 from the SD card followed by Google Apps after a reboot. In order to get MIUI to install, I had to remove the assert check at the top of the update script, because this seems to erroneously check for the A820 (even though there isn't currently a port for this device?). It's working excellently with two exceptions - I am unable to select the SD card as a storage device, and Google Play store is not searchable (it causes a Force Close).

Hi I had similar "reboot loop" problem this morning after a phone factory reset.
I have no idea how I solved that but the following was the steps I tried:
1. Install the MTK6589_PdaNET_ADB_VCOM_Drivers. Skip the USB connection during setup. Start the PdaNET after setup finished.
2. Insert battery inside the phone and connect the phone with the computer by USB
In my case, the phone reboot loop once, and the lenovo screen appeared in the second restart. The phone hanged. I unplugged the cable, took out the battery, insert the battery again and start the phone normally again and it is working now.
I recommend installing the recovery rom after you have fixed the phone.
Goodluck

Download Odin. http://www.android.gs/download-odin-3-07/
Find the original firmware for your device and download to your PC. (I can't help you with this)
Turn your phone off.
Boot into download mode on your phone (volume down + power button; hold for about 3 seconds whilst it boots).
Plug your phone into your PC via USB. Wait for the ID:COM message to show in Odin.
Follow the instructions here to flash the firmware onto your device: http://forum.xda-developers.com/galaxy-s3/help/guide-odin-flash-guide-t1671969
Reboot.
You WILL lose any data you have that isn't on an external SD card. That is the only data which will be safe.

Lenovo vibe Z90-7 brick - stucking at initializing

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
Hello,
I had the same problem. I tried with QFile and MiFlash but unfortunately without success. will you a track ?
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 .
