upload to some image sharing site (like imgur etc.), and send me in private message. It's really hard to guess without such info, and thus, hardly to say which exact rom fit in that particular phone. there are flashes for these hardware codes : A7020a48_S420_160928_TRUE_TH - HW 52 A7020a48_S318_161128_ROW - HW 50, 51, 52, 53 A7020a48_S312_160926_ROW - HW 50, 51, 52 A7020a48_S259_160721_ROW - HW 50, 51, 52 A7020a48_S236_160708_ROW - HW 50, 51, 52 A7020a48_S234_160621_ROW_IN - HW 50, 51, 52 A7020a48_S125_160419_ROW - HW 50 and few lower versions also HW code 50. p.s. You can try flashing with some of below ROM's, to see if baseband will get back to normal : A7020a48_S318_161128_ROW - ROW/EU version with FP scanner A7020a40_S318_161128_ROW(A40) - ROW version without FP scanner archive pass: lenovo-forums.ru p.s.2 As already stated before, device may be Chinese version K52e78, and conversion ROM can be found here : K52e78_china_to_A7020_S318 or K52t38_USR_ST1610 (with FP scanner) p.s.3 Useful explanation how to fix imei, wifi/bt/mac addresses, serial number, etc. How to restore nvram using Maui META 3G and SP META (use google translate. ALSO - TO BE ABLE TO FIX, when baseband is ok, you will probably need to erase nvram+nvdata partitions) b.r. Alex

Post #27. Reflash some of those rom's. If baseband returns, rest is trivial (fixing imei/sn/bt/wifi). All you need to see is that baseband appears under settings/about phone/software information If that is okay - rest can be fixed with MauiMeta and SNWriter. *** EDIT: Found some alive links : K52e78_USR_ST1615_5.518.1_1604171517_MP10V1_CN (android 5.1) K52e78_USR_ST1626_5.106.1_1606230955_mp7V2.3_CN (Android 6) Flash it and check baseband. If comes back ... you are on a good track. b.r. Alex

is to flash that "conversion rom" - K52e78_china_to_A7020_S318 - make backup of BOTH - NVRAM and NVDATA partitions - flash conversion rom with "Firmware Upgrade" in SPFT - in SPFT, with CRTL+ALT+V, write memory, write both nvram and nvdata NVRAM readback address: - start : 0xD780000 - length: 0x500000 NVDATA readback address: - start: 0x4BC8000 - length: 0x2000000 when you write nvram or nvdata, no need to input length, only start address. with this method, baseband, imei and rest should be okay. b.r. Alex

Member: 1153350 Status: Offline Thanks Meter: 0 | Can convert k52t38 or k52t58 model to get FDD-LTE B1/B3 and W-CDMA B1/B5 ? Both model can get only TDD-LTE B40 for me. Or it is network hardware alias number. Or only k52t58 model suit for my country network ? (FDD-LTE B1/B3 and TDD-LTE B40) Last edited by kaew158; 07-10-2019 at 10:01. |
