Google Nexus 6p Boot Loop Again
Nexus 6P Bootloop Fix Has Been Found, Makes Your Phone Employ 4 Cores
Have y'all been affected by the Nexus 6P Bootloop of Death? If you are i of the unlucky few with a Nexus 6P tucked away in some drawer, you'll be happy to know that a fix has been constitute that'll enable you to fully boot up your device over again.
This has been achieved by disabling the big cluster of the device's Snapdragon 810 SoC, which then allows the device to finally reach its lockscreen. In order to revive your Nexus 6P, you'll need to flash modified files provided past XDA Member XCnathan32 (with the help of XDA Senior Member rchtk) in gild to become your ROM and recovery working again.
Context
Near the end of 2016, we saw a volley of reports from multiple users claiming their Nexus 6P units were inexplicably entering random bootloops, a problem seemingly separate from the early shutdowns that plagued the phone around the aforementioned time. This was unlike, and while reduced bombardment life is certainly bad, the bootloops essentially turned the smartphone into paperweight.
Users who faced this issue quickly sunk into despair as there was no remedy in sight. No corporeality of data wiping or re-flashing of manufacturing plant images seemed to solve the trouble, indicating that the consequence was hardware-related, mayhap a trouble in the SoC. This wouldn't exist the first time for i of Google's devices to enter devastating brick or bootloop states: the Nexus vii saw widespread bricks upon receiving its original Lollipop OTA, and the LG-manufactured Nexus 5X suffered the same fate every bit many LG phones with a hardware-related bootloop as well.
The Nexus 6P bootloop issue had been confirmed by a Google representative who suggested users should contact their place of purchase for warranty or repair options. Users attempted to get a better solution out of Google, reaching out by starting a conversation in the AOSP consequence tracker, then we began hearing about a potential lawsuit being filed confronting Google and Huawei for both the early shutdown and bootloop issues. A class action lawsuit was ultimately filed and and so amended, with claimants in more ten states. While Google and Huawei were clearly made aware of the effect, we however oasis't seen them accost the trouble beyond replacing Nexus 6p bootloop devices covered under warranty.
Nexus 6P Bootloop of Expiry, Bypassed
XDA Member XCnathan32 has posted a guide and modified files that reportedly fixes the Nexus 6P bootloop issue. The instructions are quite elementary and they only involve flashing modified images for the kick.img and also a modified build of TWRP so you lot can flash other files afterwards. These builds accept been changed to only use the little cluster of the Snapdragon 810 SoC, finer disabling the A57 performance cores that are seemingly preventing the device from booting. While we won't speculate as to why this is, it does mean that you'll encounter noticeable lag, though the A53 piddling cores are besides more power efficient. It's quite the tradeoff, but information technology's certainly better than nothing.
Multiple users have reported that the modified images provided in the opening post are working and allow the device to boot, and I tried it myself on a Nexus 6P bootloop unit to confirm also. I was able to revive my younger blood brother's Nexus 6P using this method, even when Google's factory image was non working. Here are some instructions you tin can follow forth if you are looking to revive your device:
Tutorial
- Download the latest ADB and Fastboot binaries and extract them to an easily accessible folder on your computer.
- Download and install the Google USB Driver if you are running Windows.
- Download N2G48B_4Cores.img and save it to the same directory where you saved the ADB and Fastboot binaries.
- Optional: If you want to use TWRP recovery on your stock-still Nexus 6P, y'all will demand to apply a modified version. Download twrp3_1_1_4Cores.img and save it to the directory where y'all saved the ADB and Fastboot binaries.
- Optional: If y'all want to speed up your stock-still Nexus 6P, y'all can wink a modified version of XDA Recognized Developer flar2's Elemental X Kernel. Download EX4_1_1_4Cores.naught and salve it to your downloads directory.
- Plug your phone in to your computer.
- Open upwardly a command prompt or terminal in the aforementioned directory where you saved the ADB and Fastboot binaries. On Windows, you lot can hands practise this by holding shift and correct-clicking, and then selecting "open command prompt here."
- Enter the following command:
fastboot devices
- If y'all run across your device'due south series number, you are ready to motion on. If not, yous will demand to try re-installing the drivers.
- Important: your phone's bootloader MUST be unlocked in order to flash these modified images. If your bootloader is already unlocked, skip the following 2 steps.
- First the process to unlock your phone's bootloader past entering the post-obit command:
fastboot flashing unlock
- Using the volume and power keys, ostend that you want to unlock the bootloader.THIS Volition WIPE EVERYTHING ON YOUR Telephone'S INTERNAL STORAGE. But information technology's either this or bargain with a multi-hundred dollar brick. Your option!
- At present enter the following control to flash the modified boot image:
fastboot flash boot N2G48B_4Cores.img
- Optional: If you lot want to flash TWRP, then enter:
fastboot flash recovery twrp3_1_1_4Cores.img
- Optional: If you lot want to flash TWRP, then enter:
- Reboot your telephone by typing:
fastboot reboot
- After some minutes (it may have awhile), y'all should run into your phone's boot animation and eventually the lockscreen. Congrats, yous've saved your phone!
- Optional: If you want to improve the performance and yous flashed TWRP, copy the modified Elemental Ten kernel over to your telephone'southward storage, kick into TWRP, and flash the custom kernel. You tin choose to overclock the little cluster during setup to squeeze a bit more than performance out of your phone as well.
XCnathan32 does notation that root works by flashing SuperSU in TWRP. He too offered a few suggestions to become more functioning out of your device, such as disabling animations or changing the CPU governor to an aggressive 1. While he tested the modified boot.img on a stock ROM, other ROMs such as PureNexus should be able to work as well. Y'all merely demand to make sure you are running a kernel that'south modified to employ the iv little cores.
This is an impressive development and Nexus 6P owners are now able to revive their first-class device, fifty-fifty if there are compromises to this solution. Given there are many users who were unable to get their units replaced under warranty, they can now put the phone to adept employ instead of having it sit dead in a corner or drawer.
We advise you lot read the thread below in full also, and to search the thread for any questions you might have alee of posting them. Give your cheers to XCnathan32 and, if you can, help him debug the bootlooping Nexus 6P equally he'southward looking for a mode to get the large cores working as well.
