    Connect via ISP, start jtagmanager -> emmc plugin
    Click "parse connected"
    Click "display android info".

    I think that something is either broken or shorted during soldering or shield removal.

            Sorry I havent seen this in time.

            Onclite is what is in repair pack, I'll see to download Onc_EEA and prepare repair pack with bootloader files. Please DO NOT try to flash any firmware until I prepare new pack.

              Download repair pack from beta_sw folder:
              Link
              Xiaomi_Redmi_7_ONC_EEA_V10.2.8.0.PFLEUXM_ISP.riffp kg
              Select "repair bootloader" and let it finish. At this point you should be able to enter recovery and flash recovery firmware from this link:
              Link

              You can also try unlock bootloader but I'm not sure it will work. onc_eea.jpg

                Thank you very much for the work done. I restored the bootloader and the phone started. Then I downloaded the firmware through fastboot, for some reason I did not see the firmware in the recovery. It is interesting that I did not unlock the bootloader, but the bootloader was unlocked, although it was locked from the beginning. So robot bootlocker works.

                  Ok, nice to hear that phone is working now. It was version mismatch from beginning so I'm sorry that I didn't suspected it from very start.

                    Hi, I have a similar problem, I have a Device Model : Redmi 7
                    Device Name : onc
                    Architecture ABI : arm64-v8a
                    Architecture ABI List : arm64-v8a,armeabi-v7a,armeabi
                    Build Description : onc-user 9 PKQ1.181021.001 V11.0.5.0.PFLMIXM release-keys

                    I have used the files to unlock bootloader, and then the device went to 9008 mode and wonīt go out of it, if I adjust GPT will make device work again?
                    Device was perfect before writing files.

                      Yes, gpt adjusting should fix the problem.

                        Really impressed, I was using another tool and even doing a partition resize I couldnīt make it boot, so I modified my old V1 Riff with 3 100ohm resistors, then connected adjusted gpt and phone worked great.

                        Thank you.

                            resistor from vccq to dat0
                            resistor from vccq to cmd
                            resistor from vccq to clk

                            All three are 100ohm x 0.25w

                            Another way I found working excellent is like Legija says, using just one 4.7kohm resistor betwen clk and vccq, it worked for me on Qualcomm, I think a perfect solution is to put a 4.7k ohm potentiometer so you can adjust resistance, without soldering any time you want to use it.

                              I used a Bootloop on Xiaomi once. To carry out recovery work, you must install the TWRP program, which allows you to switch to the Recovery mode. You sould also have a backup copy with an earlier and workable firmware version at hand. It turned out to be the easiest way to restore the smartphone's functionality. But a few months ago, I switched to a degoogled privacy phone. Crashes occur much less frequently on this device. I hope I was able to help you. If you can't recover the data, try contacting a specialist.
