Downgrade to older bootloader / rom - Nexus 7 General

I think that my nexus 7 became more and more slow when installing new android updates. So I want to give it a try and flash a 4.1 rom, just for curiosity.. I can find older roms but I can't find older version of bootloaders. Is there any dedicated thread with older downloadable version of bootloaders? Can I extract those from factory images?
So far I learned that to downgrade I have only to flash an older bootloader and then the older rom. Is that correct? Thanks for the help.

Yes, you just need to flash bootloader, system and boot images via fastboot.. To get them just download the full 4.1 factory image from the official website

Ok I understand the point, thanks. It's the same to flash rom from internal memory or sdcard external after flash recovery?

You're posting in the wrong place. You shouldn't post here, you should post at s3 mini q&a, help and troubleshooting.
Waiting for a moderator I told it before

have you perhaps taken the time to look at the various ROMs available?
there are a few that might have the look and feel you are looking for
Only stock but AOSP themed is Enox, but it has not been updated from may last year. So..... Maclaw's AOKP.
Do you say this? http://maclaw.pl/s3-mini
Last one ?? Cm 11 right?

cm13 nightly 20131201 gapps loopboot.

i've installed cm13 nightly today and after flash the rom i've flashed gapps but when i reboot the phone he loop it. i've tested without the gapps and the phone start it on boot. what could be the problem? thanks for helps
Try factory reset, clear dalvik and cache.
It's still new, so nobody can guarantee that it will actually work, nobody tests nightlies, but those who download them.
I've tried but is the same. Surely is a ROM problem. I will be wait next month for a stable ROM

There are no official stable versions anymore (called snapshots), not for all versions (for shamu there isn't).
But for sure in a month it will be more stable.

If it boots without the gapps, try different gapps. I use http://opengapps.org/ 6.0 Stock on my personal CM 13 builds without issue.
These was the gapps that i've used. But nothing is changed

You might try re-downloading the gapps and the cm rom, one of them might be corrupted somehow.
When i can surely i will try to download the ROM. Now i remain with the cm 12.1.

Could be a file system problem?

Root + Recovery

Hi i have z3 compact d5803 with original firmware 23.4.a.1.264 and with lock bootloader. I want only root d5803 and install recovery TWRP, Where i can found guide?
Well it is pretty easy to do,basically you download Kingroot and Supersu-me,and you firstly root your phone with Kingroot and then you open up the Supersu-me app and it will remove Kingroot and it will put SuperSU,and then you just need to download XZDualRecovery and install it and that's it!

I had to do it with king root desktop app (it is on chinese or something i dunno, i clicked all the blue buttons until i managed it to work). It all worked until I decided to reboot. Got stuck on a bootloop until i flashed the stock firmware again.

I need FW stock WAS-LX1AC02B113, P10 Lite

I need the stock firmware WAS-LX1AC02B113 to restore my Huawei p10 lite because it does not update anymore and reports an error in the installation. Please help me find this firmware.

Thanks for having responded, i've already tried the b114 but the problem does not work after a hard reset i get the update ota B120 and when i start the installation fails and says the package is corrupt. I would need the stock firmware to reset the phone to factory conditions

How are you trying to install?
Choose full firmware not ota.
Check if the firmware are approved before installing.

I tried the full ota b114, the B115 and the B120 are not approved, but the odd thing is that after hard resetting, I get an update via Ota the B120, which if I try to install I'm out of this screen (photo Of example) and when I start the phone I will also see this screen
Inviato dal mio WAS-LX1A utilizzando Tapatalk
Yes it seems you need the same firmware you have b113 to fix it.
You can try erecovery, while usb connected hold volume up + power.
Or use this methodhttps://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
But p10 lite not supported yet hope it will be soon.

So without the b113 stock firmware I can install another version after unlocking the bootloader and should I fix the problem?

Yes you can with this tool.
Okay, but is it okay if firmware finder says it is not approved? So in theory could I also make the debrand with this method?
I could also use the Huawei Multi Tool that is compatible with the P10 Lite

Yes you can install any firmware with this tool even if it's not approved and you can rebrand to any region.

I tried to flash a version of Europe so no brand and unfortunately nothing happens I think I go into a kind of bootloop, I do not know if there is a specific firmware or it's all worthless and you have to wait for some other method, anyway I will try again Flash the latest update of my B120 brand
Inviato dal mio WAS-LX1A utilizzando Tapatalk
Ehy and what do you tell me about the oeminfo c432? However I tried to flash a couple of different European firmware and did not work, the only one that worked is the WAS-LX1AC02B114, I do not understand why
