A820 BOOT LOOP Problem
I have an A820 that suddenly became unresponsive , crashed and all it did was to boot with the logo screen and then restart to the same screen and nothing more.
I have tried to reflash with original FW but nothing. Tried even an MIUI version but with the same result ( this time showing MI logo ) I have the correct drivers and tried with more than one version of Flash tool all to no avail. I dont know how to fix this phone. I cant get into recovery although factory and meta mode do show up if I flash original FW but no recovery , and tried to flash more than one version of that as well to no effect. This phone wont budge further than the logo screen and just keeps looping. Is there a fix at all for this ? Someone mentioned the PDA NET fix, still nothing with that.
Please help... i'm losing my mind.

If your phone can go into the factory mode, then try to use adb command line for debugging: you mentioned that there is not recovery. To be sure that the recovery does not work, use the
Code:
adb reboot recoveryThis is what I would do if I were you.
using sp tool:-there are certain rules with regards to posting external links. that is standard in most sites.
but again, i m not quite sure..couldnt check the rules and stuff
fORMAT (Auto)
Check the (DA DL Checksum) option
Select Firmware Upgrade
then click download.
Repair Nv data with other tools if you have no backups and youare good togo
Reboot after Meteos
HI i used meteos apk and set partition to 2.7 gb on my lambda last version firmware.Very nice til now in recovery i wiped the data and after restart all god.I installed some apps from google play and the phone worked great but after a while i tried to swipe the unlock sceen to call somebody and the phone restarted and it makes like this on and on when i unlock the screen.
Also it see only one SIM and that is on roaming but the roaming is deactivated.
Any help will be verry apreciated.

Hi again. I managed to "brick" my lenovo A820 again, just by doing a factory reset from Miui rom that actually worked a few months ago. Now I get a boot loop and can't find my way into flashing it again. I'm running windows 10 now. Might this be the issue? I tried flashing with SP_Flash_Tool_v5.1352.01 and the original 139 rom from here: http://www.needrom.com/download/lenovo-a820-11/
It does nothing, like it does not even connect to it. In device manager I see it like Lenovo A820 but with the warning icon.
Thanks!

I would suggest use win-xp or x7. They are more reliable for flashing MTK phones (even if the w8 works for me for it).
The flashtool does not do anything if the driver is not correctly installed.
(I'm a fogy person, so I use w7)
Be careful with the preloader!
Use your own preloader, if you have that. If not, do an MTKDroidTools backup in factory mode.
There are 4 different preloaders for A820; if you choose a non-proper for yout phone, it will be a half-brick, which can be recovered with another (or your original) preloader.
Hey Cappa, thanks for your reply. I managed to get it working on win 10 with the same drivers. Just had to connect it only after hitting "Download" or"Firmware Upgrade".
Best!

5Lenovo A820
So I solved the issue and got everything I actually wanted.
So after some flashes and reformats (of the same rom as I didnt have other) I finaly checked the DA DL All with Check Sum in the upper right corner and reflashed again. Then the phone started ok with the custom rom however with some issues, 1.Invalid IMEI , 2.Play store not actually working , 3. Even more preinstalled chinese apps.
However my concern at this point was the imei. I dont know if the imei was lost after the first reflash or because I formated the flash, all of it in Flash Tools. What I mean is I dont know if youll experience this too, but you should backup your imei(there is some info on the net about a file you should backup, didnt look much into it as it was too late for me) before flashing > I read that some people lost the imei even after factory resetting their lenovo phone (wasnt my case, I actually resetted it bunch of times ahter I fixed the imei).
Because I didnt like the rom, kept looking and finally found the official lenovo one on a russian site (used google translate). I flashed this rom with Flash tools and the phone was back to factory state - IMEI.
Rewriting the IMEI was kind of a pain (not because was finally hard, but because I found the info hard). Its a dual sim phone so it has 2 imei, one of them was below the battery written and the other one dont know. So I wrote the same imei for both (doesnt bother me as I wont use the dual sim function, just the on).
At this point the phone was exactly how I received it , so far I only repaired the damaged I made.
Then I went back in Flash tools and this time I only flashed the recovery and boot image (from the recovery-a820 archive found on needrom site and with the instructions there) - BTW: First time I didnt do this because the custom rom I found there was flashable with flash tools and it contained recovery allready. But now I decided not to install the custom rom anymore, so I just flashed the recovery mode.
Started the phone and discovered Root Explorer and superuser (both in chinese, but figured them out).
Then I reboted in recovery mode because I was curious what the is , also was in chinese.
My next goal was to get google play working. So downloaded google play apk, google services framework apk and google login services apk from different sources and placed them on the sd card. The point was to move those 3 apk files to system/app but since root explorer was in chinese I douwnloaded some other file manager that could access root also, moved the files to system/app and restarted the phone but nothing happened. Checked again to see if the files were still in the system/app folder, they were, but the permission was 600(I belive thats corect , superuser had read/write and the others nothing). So I downloaded a bunch of other file manager so I can change those file permissions but none of the ones I downloaded worked(I mean to change permissions). Eventually I downloaded link2sd , uninstalled the chinese root explorer and with this oportunity all the other chinese built in apps I had no interest in (not the lenovo ones, the woo ones and the ones that didnt even had title in english). Then I installed root explorer in english , and managed to change the permissions on those files to 644 then restarted my phone.
Google play store installed at boot and appeared in the menu (so did the root explorer in chinese, I belive I shouldve replace its apk in the superboot folder, but whatever, dont need it anymore). Runned Play store but it didnt actually start (Kept on saying Google play has stopped working), so I went in settings > apps to clear the cache for the play store app and noticed there the play store size was 00 everywhere so I guess the installation wasnt so successfull. However I then went to the play store apk from sd card and installed it again (normally like any apk), warned me it is going to replaced a system app , I agreed and it installed successfully. Now Play store runs perfectly , downloaded a bunch of apps for testing and really runs perfectly.
So as it turns out to root the phone and install Play store isnt as hard as I made it be. Good luck to you and I hope this info will help you.5Non-Lenovo rom for A820
If anybody is interested, I made a non-Lenovo based rom for this phone.
It can be installed through CWM.
Thanks - again - for bgcngm http://forum.xda-developers.com/showthread.php?t=2246874 for the base of the rom.
The rom is available here
Please note that this update really change your phone's appearance.
This is rooted, and does not contain Chinese suspicious softwares.
It is simple as possible, so if you want to use googleapps, then you shall install it from CWM.5A820 JB 4.2.1 port from ZTE V987.
Many thanks to bruno, it's based on his B01 ROM!
The ROM is permanently rooted, multilanguage and has the stock Android look and feel.
Gapps not included, but you can install through CWM/TWRP, this package works fine: http://goo.im/devs/UniqueDroid/gapps/gapps-4.2.1/gapps-jb-4.2.1-20121129-signed.zip
Keep in mind this is in alpha stage, although everything seems to work. I've verified it doesn't mess up the touchscreen, so it is safe to flash.3If you look some post up you will see some links you can use.
@TheTen: If you have root you can remove the start and shutdown movie and sound (4 files). It will boot an shutdown with the stock Android animated text logo.
