Firmware updater: bypass version checks?
Hello!
I recently purchased a PRS-T2 (European version) with firmware 1.0.04.11081... and, obviously, immediately tried to root it. However, it seems locked. I seem to have found a way to bypass version and model checks in PRS-T2_UPDATER_*.EXE but... now I am stuck again: - Re-installing 1.0.04.11081 (whether EN or US) works, but doesn't allow jailbreaking. - Actual downgrading seems to work at first, but displays an error message after automatically rebooting the device. I guess a second set of version or checksum verifications is happening on-device; any thoughts? Here is the method I used: 1. Do not run the executable; instead, unpack it with 7zip. 2. Edit "PRS-T2_UPDATER_*\eBookUpdater\scripts\updater.xml" : Remove "// check model name and is specified revision as well" and the following 4 lines. Remove "if (this.isNewerOrEqualVersion(version)) {" and the following 5 lines. Don't touch the next few lines (Starting with "this.") but remove the two lines containing only "}". 3. Launch upgrade using "PRS-T2_UPDATER\Reader Updater.exe"! |
