Downgrade Lenovo A7000 from Marshmallow to Lollipop - Possible - Lenovo A7000 Guides, News, & Discussion

Hi everyone,
I was fed up with marshmallow and had wanted to downgrade to Lollipop 5.0 searched the internet but found no supporting evidence of anyone successfully downgrading. Even people updated stating the official status is that you CANNOT downgrade.
I today took the risk and tried to downgrade to Lollipop S136 version using SP flash method (download only).
I confirm that the downgrade was successful and now my phone is on Lollipop S136 version. Just thought of sharing to all who desperately wanted to downgrade. Hit thanks if you find it helpful

Hi! I succesfully downgraded my phone to android 5.0 lollipop. Everything works fine except my sd card -it says my sd is corrupted but that's not true because on android 6.0 marshmallow that sd worked. I also tried different sd card but nothing changed. I even tried to format sd card but it still doesn't work. Is there some way how to fix it ?

Same problem here

Anyway to Downgrade from 5.1.1 (COJ5) to 5.0.1 ?! N910C

can i downgrade from 5.1.1 N910CXXU2COJ5 to any 5.0.1 ?
If Yes , How can i do so please
Why i want to do so , i want to run MIUI :angel:
no one knows !
I'm having the same problem here. After the OTA update to COJ5, Odin always fail to flash any ROM before COJ5 (device display the message sw rev.check fail device 2 binary 1). Also, all the root methods that worked on COJ4 stopped working in this new version, always resulting in a infinite bootloop forcing me to reflash COJ5 in Odin. I even went to TWRP and completely wiped my phone (including system) but still coudn't install any previous version (installing the SuperSU through TWRP also results in infinite bootloop now). Did anyone find a solution for this yet? I'm guessing that this won't be a problem for just Galaxy Note 4....

Well, while [5.1.1 COJ4] can be downgraded to 5.0.1, [5.1.1 COJ5] can't. The problem may be exactly the bootloader that cannot be downgraded through ODIN. I don't believe that any common procedure will work for this downgrade. We will likely need a different approach.
I also read in some forum that while Odin won't work anymore, TWRP (or CWM) still will. So this leads to other two questions:
* Is there any place we can download stock roms in recovery format instead of ODIN's?
* If not, is there any way we can convert Stock Roms from ODIN's format to TWRP's?

if that is the case get a backup from your friend or someone with the same model like you and make sure they have a kitkat or 5.0.1 version
I have the same problem, after updade coj5 I can not downgrade to kitkat 4.4.4
@amidsal and @kirbiii, did you try this and get it to work? If so, how did you do it?

Sadly no. I'm still believe that the best (if not the only way) right now is through JTAG.
Excluding direct access to the internal SD Card, the only way to overwrite the protected memory in the device is through the bootloader, which is protected itself.
I did managed to downgrade my note 4 N910U from 5.1.1 to 5.0.1.

Upgrading to Marshmallow without using OTA

Is it possible to install Marshmallow on my device without using the standard OTA? I have a device I would like to upgrade to the latest android OS, however it has no sim card (testing device)

Sure, you can update to Marshmallow v6.0 using Odin3.
You don't need a sim card to Odin flash firmware.
You need to go to http://sammobile.com and download
the official samsung S6 Edge firmware for your phone's
specific model and flash it using odin3.
Good luck,
Have a great day!
You must wait for others suggestions but I think you can root and flash via g928f method and firmware. Your model is 928X?

As far as i remember there should be an option to disable the checking for updates.
Go to about device then software update, uncheck auto update

Unfortunately, there isn't any way to downgrade as far as I know. It only happened for J500H and there is a warning thread, but not all people are aware of that...
You gotta blame Crapsung...

you want to go back to nougat from oreo , am i right ? Then try this video, if it doesnt help please reply to me and i am gonna find a solution to you ASAP
1) https://www.youtube.com/watch?v=qqpucWXyfqY
hi. thx, but i did this right (like in the video) many times, and it worked perfectly. now is not working cuz the bootloader was updated, and it won't let me downgrade the firmware anymore. i am still trying to find a way but i don't know if is possible.
i am searching a way to downgrade bootloader and then downgrade the firmware, but i dunno if is possible to downgrade bootloader once it was updated.
i am looking for the same solution. i managed to downgrade to Nougat but cant install custom rom
Can someone help me? I have G950FD which Firmware should I flash for my phone? I am using this model in the US
So no solution to downgrade bootloader version?
Bootloader downgrade for U6 is not available yet (For free)

I have searched the whole web. but, I haven't find the solution to downgrade the bootloader for Binary 6. Well, my phone's OS is dead after upgrading to pie. So, apparently the only way for me and to others who are facing the similar issue is to wait until someone releases Binary 6 combination firmware for SM-G950FD.
Good news: It's easy to get your phone running if your bootloader is not upgraded to binary 6. Cuz, Binary 5 firmwares and combination files are available out there and they are 100% working unless your MB is dead.
Note: I have flashed following stock firmwares successfully through ODIN [INS-G950FXXU6DSK9-20191231094010 and INS-G950FXXS6DTA1-20200120123810] yet no luck. Can't boot the OS. Tried to root the phone, cant able to flash the custom recovery. Nothing just works.
Someone, please tag me if ever finds U6 combination file. That's the only hope to bring back my phone to life.
