A972T01本地降级测试已砖，无法开机
最近家里的电视广告越来越多，系统也频繁升级，于是着手降级和精简，发现帖子下载了对应机芯的固件，由V8-A972T01-LF1V396系统内降级V8-A972T01-LF1V093
结果走完进度条直接黑屏没反应了，降级过程中没有人为干预断电重启，
[升级&刷机] TCL电视 部分机芯固件最全集合+刷入教程 继前日发叻一篇关于“TCL电视 系统降级、屏蔽广告与升级、免root精简系统并刷入第三方内置应用...”旳帖，发现自从TCL铁粉社区关闭不再开放后，寻找各类机芯旳固件已然成叻一大难题，现网上提供旳大部分固件又是需要付费购买旳，这就让人很不开心叻~{xiaolu8}下面将本人现有旳库存..固件包/强刷包全部分享给大家，机芯适配且有需求旳可取走啦 ↓ ↓ ↓
于是找了一个强刷包
V8-A972T01-LF1V358_less_impdata zip
断电，插U盘，按住机身电源按钮，插电。等了几十秒同样还是没有反应
电源指示灯也不闪，屏幕也不亮
请求支招！！！
活该。你不是 第一个被坑的。你是 第30+后面的坏电视 。还会有更多人被坑。 {znds8}{znds8}感谢楼主分享 TL1:BL:c60c31:eab5ad;FEAT:E0F97180:20282000;POC:F;RCY:0;EMMC:0;READ:0;pbl2_stage_init1L0:00000000 L1:00000700 L2:00008000 L3:00000000 S1:00000000 B2:20282000 B1:e0f97180TE: 105388BL2 Built : 18:07:14, Sep 27 2019. tl1 g8337d09 - niko.he@droid05-szBoard ID = 2 Set cpu clk to 24M Set clk81 to 24M Use GP1_pll as DSU clk.
